Description
Technical Field
The present invention relates to a toothbrush sterilizer, and more particularly, to a toothbrush sterilizer for a plurality of toothbrushes capable of accommodating a plurality of toothbrushes.
Background
Modern people brush their teeth several times per day with toothbrushes for oral health.
However, in many cases, toothbrushes are stored in bathrooms with high humidity and poor ventilation, and the toothbrushes are naturally dried, so that the toothbrushes are not individually sterilized.
Therefore, harmful microorganisms such as bacteria are bred by moisture or nutrients remaining after the toothbrush is used, and thus the hygienic condition of the toothbrush is generally in a poor state.
Thus, if a contaminated toothbrush is used, there is an increased risk of suffering from various oral diseases such as periodontitis, especially those with weaker immunity than healthy persons, being more susceptible to infection with pneumonia, bronchitis, hepatitis, cold, etc., and thus it is necessary to keep the toothbrush clean after use to prevent bacterial growth.
Accordingly, toothbrush sterilizers using ultraviolet sterilization have been recently developed and used.

Therefore, the bacteria in the toothbrush bristle is greatly inhibited from breeding, and the cleaning state of the toothbrush is further improved.
At this time, the toothbrush holder is formed in a stepped shape having different heights from each other when air is introduced from the side of the toothbrush holder. The bristle parts of toothbrushes placed in the layers of the toothbrush holder also have a height difference. Accordingly, the wind blown to the bristle part side is stably sent to the bristle part side of the brush holder without being hindered by other bristle parts, and thus a more rapid and efficient drying operation of the bristle part is achieved.
In addition, in the case where the brush holder is formed in the shape of parallel strips, the air blown toward the bristle part side is blown from the upper side toward the lower side, and is not blown from the side surface portion of the bristle part, so that the air is blown safely and effectively toward all the bristle parts placed on the brush holder.
In addition, since ultraviolet sterilization of the bristle part is performed by the ultraviolet irradiation unit, bacterial growth of the bristle part can be prevented or suppressed.

In addition, the terms used in the present specification are terms used in order to appropriately describe the embodiments of the present invention, and may be different according to persons or practices associated with the field. Accordingly, the definitions for this term should be defined based on the content of the entire specification.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. The use of "including" in the specification is intended to specify the presence of stated features, regions, integers, steps, actions, components, and/or groups thereof, but does not preclude the presence or addition of other features, regions, integers, steps, actions, components, and/or groups thereof.
Hereinafter, a toothbrush sterilizer according to an embodiment of the present invention will be described with reference to the accompanying drawings.
First, referring to fig. 1 to 4, a toothbrush sterilizer according to an embodiment of the present invention is described.
Referring to fig. 1 to 3, a toothbrush sterilizer of an embodiment of the present invention may have: a housing 1 having a main body 11, a motor mounting portion 12, and a power supply mounting portion 13; a drive module 2 to which a plurality of ultraviolet irradiation units 21 are mounted, the plurality of ultraviolet irradiation units 21 irradiating ultraviolet rays to the inside of the main body 11 of the housing 1; a toothbrush holder 3; a fan 4 coupled to a motor (not shown) which is located at the motor mounting portion 12 and is electrically connected to the driving module 2; a power supply unit 5 mounted on the power supply mounting unit 13; a first side cover 61 and a second side cover 62 located on respective sides of the motor mounting portion 12 and the power supply mounting portion 13; a front cover 71 and a rear cover 72 respectively located at the front and rear of the main body 11 to cover the open front and rear faces of the main body 11, respectively; the mounting portion 8 is attached to the rear cover 72.
The casing 1 has a plurality of air inlets H113 and H61 at one side thereof, and external air is introduced into the casing through the plurality of air inlets, thereby being able to be blown toward the bristles 110 of the toothbrush 100 positioned in the casing 1.
In addition, as shown in fig. 2 to 4, the housing 1 may have a first space S11 and a second space S12 inside, the first space S11 being a toothbrush placement space in which a plurality of toothbrushes 100 are placed, the second space S12 may be provided with a driving module 2, etc. Thus, the drive module 2, the brush holder 3, the fan 4, the power supply portion 6, and the like can be protected from these empty spaces S11, S12.
As described above, such a housing 1 may have: a main body 11; a motor mounting portion 12 located at one side (e.g., left side) of the main body 11; the power supply mounting portion 13 is located at the other side portion (e.g., right side portion) of the main body 11.
In this example, the shape of the toothbrush sterilizer generally has a hexahedral shape such as a rectangular hexahedron, but may have various shapes such as a cylindrical shape, unlike this.
The shape of the body 11 may also be based on the shape of the toothbrush sterilizer, and the body 11 of the present example may generally have a hexahedral shape with open front and lower faces.
Thus, the present example body 11 may have: an upper face 111, a rear face 112, a first side face (e.g., left side face) 113, and a second side face (e.g., right side face) 114.
The width W11 of the upper surface portion 111 is smaller than the width of each of the side surface portions 113, 114, and thus the first side surface portion 113 and the second side surface portion 114 may protrude forward from the front-side end of the upper surface portion 111. Thus, the respective edge portions (i.e., upper edge portions) of the first and second side face portions 113, 114 connected with the upper face portion 111 may exist without the upper face portion 111.
Accordingly, a portion of the respective edge portions of the first and second side portions 113, 114 may be exposed, not covered by the upper face portion 111.
The rear surface portion 112 may have a plurality of windows WD112, and the plurality of windows WD112 expose the respective ultraviolet irradiation units 21 so that ultraviolet rays outputted from the plurality of ultraviolet irradiation units 21 are outputted forward. Thus, the number of windows WD112 may be the same as the number of ultraviolet irradiation units 21.
Such respective windows WD112 may be blocked with a protective film WD113 composed of a transparent material that transmits ultraviolet rays. Thus, foreign substances such as water or dust can be prevented from entering the driving module 2 to which the ultraviolet irradiation unit 21 is mounted through the open window WD 112.
In this example, although the shapes of the respective windows WD112 are all the same, the heights may be different from each other, and the heights of the respective windows WD112 may be determined according to the heights of the bristle parts 110 of the respective toothbrushes 100 placed in the toothbrush holder 3. Thus, each window WD112 may be located at a height corresponding to each of the bristle sections 110 located on the brush holder 3.
Such each window WD112 has a quadrangular planar shape such as a rectangular quadrangle, but is not limited thereto, and may have various planar shapes according to the shape of the plurality of ultraviolet irradiation units 21.
The first side surface portion 113 may have a plurality of air holes H113.
Such a plurality of air holes H113 may be distributed along the planar shape of the first side surface portion 113.
In this example, the diameters of the plurality of air holes H113 located at the first side surface portion 113 and the interval distance between the adjacent two air holes H113 may be the same or different. Here, the separation distance may be a distance connecting the center points of the two air holes H113 in a straight line.
The diameters of the plurality of air holes H113 may be different depending on the positions, for example, the diameter of a portion corresponding to the bristle part 110 of the toothbrush 100 placed in the toothbrush holder 3 may be larger than the diameter of the other portion.
In addition, for the interval between the adjacent two air holes H113, the diameter of the portion corresponding to the bristle part 110 may be smaller than the interval between the other portions.
Accordingly, the portion of the first side surface portion 113 corresponding to the bristle portion 110 may be provided with more dense and larger air holes H113 than the portion not so, and thus air may smoothly circulate through the portion of the first side surface portion 113 corresponding to the bristle portion 110.
Unlike the first side surface portion 113, the second side surface portion 114 may have a plate shape with a plane surface that is entirely blocked.
Because of this structure, there may be a first space S11 surrounded by the upper face 111, the rear face 112, the first side face 113, and the second side face 114 and opened at the lower face and the front face in the main body 11.
The motor mounting portion 12 may have a hexahedral shape with an open one-side surface portion (e.g., left-side surface portion).
As shown in fig. 2 and 3, such a motor mounting portion 12 may be attached to the first side surface portion 113.
At this time, the first side surface 113 may be extended rearward by a predetermined length. Accordingly, as shown in fig. 2 and 3, the width W12 of the motor mounting portion 12 may be larger than the width W11 of the main body 11, and thus the motor mounting portion 12 may protrude rearward from the rear face portion 112 of the main body 11.
The motor mounting portion 12 may provide a space in which the fan 4 combined with a motor (not shown) may be placed. For this purpose, a mounting bracket 121 may be provided inside the motor mounting portion 12, and the mounting bracket 121 mounts the fan 4 coupled to the rotation shaft of the motor.
The mounting bracket 121 may be provided along the width direction of the motor mounting portion 12, and a mounting hole H121 for mounting the fan 4 may be provided at a middle portion.
The motor mounting portion 12 may include: a drive switch SW1 for driving the fan 4; an operation display LD1 configured with at least one light emitting diode or the like having at least one color to indicate at least one of an operation state and a power supply charge state of the driving switch SW1; a time display LD2 displays at least one of a current time and a reserved time.
At this time, the time display LD2 may have 7 segments, but is not limited thereto.
Unlike the present example, in the alternative example, at least one of the action display LD1 and the time display LD2 may be omitted as needed.
Similar to the motor mounting portion 12, the power source mounting portion 13 may be attached to the second side surface portion 114 of the main body 11, and may extend rearward from the second side surface portion 114. Thus, as with the motor mounting portion 12, the width W13 of the power supply mounting portion 13 may be greater than the width W11 of the main body 11, and thus the power supply mounting portion 13 may protrude rearward from the rear face portion 112 of the main body 11.
At this time, the width W12 of the motor mounting portion 12 and the width W13 of the power supply mounting portion 13 may be the same as each other.
A mounting groove P13 for mounting the power supply portion 5 may be provided in the power supply mounting portion 13.
In this way, since the motor mounting portion 12 and the power supply mounting portion 13 extend rearward from the rear face portion 112 of the main body 11, a blank space, that is, the second space S12, may exist between the rear face portion 112 of the main body 11 and the motor mounting portion 12 and the power supply mounting portion 13 protruding rearward from the rear face portion 112 of the main body 11. At this time, a bottom plate (not shown) blocking the lower portion of the empty space S12 may exist between the motor mounting portion 12 and the power supply mounting portion 13, and the lower portion of the empty space S12 is blocked by such a bottom plate.
Thus, such a second space S12 may be a sealed space surrounded by the motor mounting portion 12, the power supply mounting portion 13, a bottom plate, not shown, and the rear cover 72.
In the present example, the first side 113, the motor mounting portion 12, and the first side cover 61 on the first side constitute one side portion of the housing 11, and the second side 114, the power mounting portion 13, and the second side cover 62 on the opposite side of the first side, that is, the second side, may constitute the other side portion of the housing 11, centering on the rear surface portion 112 of the main body 11.
The driving module 2 serves as a control module for controlling the operations of the plurality of ultraviolet irradiation units 21, the fans 4, and the displays LD1, LD2, and the driving module 2 may mount electronic components necessary for the operations, such as a fan driving part (not shown) for operating the fans 4, and the like.
Such a driving module 2 may be constituted by a printed circuit board and may be located in the second space S12 at the rear side of the main body 11.
The electronic components located in the driving module 2 are electrically connected to at least one of the devices related to the electronic components, i.e., the power supply unit 5, the driving switch SW1, the operation display LD1 and the time display LD2, so that the operation of the devices can be controlled.
Accordingly, the driving module 2 receives power necessary for operation from the power supply unit 5, and can control the operation of the fan driving unit and the operation display LD1 according to the operation state of the driving switch SW 1.
The driving module 2 controls the number of lights or the brightness of the operation display LD1 according to the charging state of the power supply 5, and the user can confirm the amount of electricity charged to the power supply 5 by using the lighting state of the operation display LD 1.
The driving module 2 controls the lighting state of the time display LD2 according to the operation of the user by the driving switch SW1 or the like, and further can set the current time or the reserved time of the ultraviolet irradiation unit 21.
In the case where the motor drive for rotating the fan and the operation of the time display LD2 are controlled by the drive switch SW1, as an example, if the drive switch SW1 is operated for less than a set time (for example, 3 seconds), the drive module 2 sets the motor operation for rotating the fan for a period of time.
However, if the driving switch SW1 is operated for a set time or longer, the driving module 2 may determine that the time display LD2 is used for a time setting operation.
Accordingly, when the driving switch SW1 is operated for a set time or longer, the "hour" display portion of the time display LD2 is turned off by the operation of the driving module 2 to display a time setting state, and in this time setting state, the driving switch SW1 is briefly operated for a time shorter than the set time to adjust to a desired time, and then the driving switch SW1 is operated for a set time or longer to set the adjusted time. When the hour adjustment is completed, the time display device automatically changes to the minute setting state, and the "minute" display portion of the time display LD2 turns off the light to display the minute setting state, and the drive switch SW1 is operated in the same manner as the hour setting operation, so that the "minute" setting operation can be completed.
For each ultraviolet irradiation unit 21 attached to the driving module 2, at least one ultraviolet light emitting diode (UV LED) may be provided as an example, but not limited thereto, but at least one ultraviolet lamp or the like may be provided.
Each of the ultraviolet irradiation units 21 may be lighted to irradiate ultraviolet rays by an operation of a driving part (not shown) attached to the driving module 2.
In this example, each of the ultraviolet irradiation units 21 may be located at a position corresponding to each of the windows WD112 located in the main body 11, and as described above, the heights of the respective windows WD112 are different from each other, and thus the positions of the plurality of ultraviolet irradiation units 21 located at positions facing each other with the respective windows WD112 may also be respectively different.
Thus, the ultraviolet rays irradiated from the respective ultraviolet irradiation units 21 can be irradiated into the first space S11 where the toothbrush holder 3 is located through the respective corresponding windows WD112 formed in the rear face 112 of the main body 11.
As described above, the height of each window WD112 is a height that can face the bristle portion 110 of the toothbrush 100 placed on the brush holder 3, and thus the ultraviolet rays passing through each window WD112 can be directly irradiated to the corresponding bristle portion 110 side.
Accordingly, the ultraviolet light outputted from the ultraviolet light irradiation unit 21 is irradiated to the brush part 110 having bristles, i.e., the brush part 110 having bristles, which is the brush part of each of the toothbrushes 100 facing each other, through the corresponding window WD112, and the operation of sterilizing the brush part 110 is performed by the ultraviolet light.
At this time, the ultraviolet rays irradiated from the respective ultraviolet irradiation units 21 are directly irradiated to the corresponding bristle part 110 side, so that the ultraviolet sterilization effect and drying effect on the bristle part 110 can be further improved.
In the case where each of the ultraviolet irradiation units 21 has a plurality of ultraviolet light emitting diodes or ultraviolet lamps arranged in parallel in at least one of the vertical direction and the horizontal direction intersecting the vertical direction (i.e., the extending direction of the housing 1), the number of ultraviolet light emitting diodes or ultraviolet lamps arranged in parallel in the vertical direction may be determined according to the length of the bristle part 110, and the number of ultraviolet light emitting diodes or ultraviolet lamps arranged in parallel in the horizontal direction may be determined according to the diffusion range of the light outputted from the ultraviolet irradiation unit 21 and the maximum number of toothbrushes to be mounted.
The brush holder 3 may be located in the first space S11 of the main body 11, and may be mounted on the first and second side portions 113 and 114, respectively, which are spaced apart in the horizontal direction, for example. Thus, one end (e.g., left end) of the toothbrush holder 3 is mounted to the first side surface portion 113, and the other end (e.g., right end) located at the opposite side of the one end may be mounted to the second side surface portion 114.
Such a brush holder 3 has the same width regardless of the position, but may have a stepped shape having a plurality of layers ST31, ST32 having mutually different heights according to the position.
As an example, the toothbrush holder 3 may have a first layer ST31 and a second layer ST32, the first layer ST31 having a first height and the second layer ST32 having a second height higher than the first height, and toothbrush insertion grooves H31, H32 into which one toothbrush 100 is inserted may be provided at each layer ST31, ST 32.
In the case of the present example, one toothbrush insertion groove H31, H32 is provided in each layer ST31, ST32, but a plurality of toothbrush insertion grooves may be provided unlike this. In this case, two or more toothbrushes 100 may be inserted in parallel in each of the layers ST31 and ST 32.
At this time, the heights of the first layer ST31 and the second layer ST32 different from each other may be determined by considering the air passage through which the air flows by the operation of the fan 4 located at the first side surface portion 113.
Although the heights of the respective layers ST31, ST32 of the brush holder 3 have been determined, the mounting positions of the window WD211 and the ultraviolet irradiation unit 21 may be determined in correspondence with the heights of the bristle parts 110 of the respective toothbrushes 100 placed in the layers ST31, ST 32.
The brush holder 3 may be formed of an elastic material having elasticity.
Thus, the user can insert the brush neck portion of the toothbrush 100 into the insertion grooves H31, H32 or remove it from the insertion grooves H31, H32.
As shown in fig. 4, by such a shape of the brush holder 3, the plurality of bristle parts 110 located at the brush holder 3 may also be located at mutually different heights, and thus two bristle parts 110 adjacent in the horizontal direction may have portions that do not overlap each other in the horizontal direction.
Accordingly, since each of the bristle parts 110 is directly faced with the plurality of air holes H113 located in the first side surface part 113, the air flowing in through the air holes H113 is not blocked by the other bristle parts 110, but is directly blown to the side of each of the bristle parts 110, and thus the drying efficiency of each of the bristle parts 110 can be improved.
That is, since the overlapping area between the horizontally adjacent bristle sections 110 is not present or is reduced to the maximum extent by the step-shaped brush holder 3, the wind entering through the plurality of air holes H113 of the first side surface section 12 is directly dispersed toward the respective bristle sections 110 at different heights from each other, and thus the operation of drying the bristle sections 110 by the air can be smoothly performed.
As described above, the fan 4 coupled to the motor is mounted on the motor mounting portion 12, and can be rotated in a corresponding direction by operating the drive switch SW 1. External air is sucked into the motor mounting portion 12 by the rotation operation of the fan 4, and the sucked air can be injected into the first space S11 of the main body 11 through the plurality of air holes H113.
The driving time of the fan 4 may be set in advance, and may be rotated only for a set time every time the driving switch SW1 is operated.
The power supply portion 5 is mountable in a mounting groove P13 located in the power supply mounting portion 13.
Such a power supply section 5 may be a battery charged by a power supply applied from the outside through the second side cover 62 facing each other, and may supply power to components necessary for the operation of the toothbrush sterilizer, such as the driving module 2, the operation display LD1, the time display LD2, and the motor.
The first side cover 61 serves as a cover covering the open face of the motor mounting portion 12, that is, a cover covering the side face, and protects the motor and the fan 4 located in the motor mounting portion 12.
As shown in fig. 2 and 3, the first side cover 61 may be formed in a net shape having a plurality of ventilation holes H61.
The second side cover 62 is a cover that covers the side surface, which is the open surface of the power supply mounting portion 13, and protects the power supply portion 5 located in the power supply mounting portion 13.
Such a second side cover 62 has a terminal connection hole H62 for charging the power supply portion 5, and thus may be formed in a planar shape in which all but the terminal connection hole H62 is blocked.
As such, the first and second side covers 61 and 62 are mounted at left and right sides of the housing 1, respectively, and thus the first and second side covers 61 and 62 may constitute left and right sides of the housing 1, respectively.
As described above, since the plurality of ventilation holes H61 are provided in the first side cover 61 covering and mounting the motor mounting portion 12 of the fan 4, the outside air can enter the motor mounting portion 12 through the ventilation holes H61 of the first side cover 61 by the rotation operation of the fan 4.
As described above, the plurality of air holes H113 located at the first side 113 of the housing 11 and the plurality of ventilation holes H61 located at the first side cover 61 may constitute a plurality of air inlets located at one side of the housing 1.
Thus, the external air can be blown to the brush holder 3 side located in the main body 11 of the housing 1 through the plurality of air inlets H61, H113 by the rotation of the fan 4.
The air introduced into the motor mounting portion 12 can be blown into the first space S11 in the main body 11 where the bristle part 110 is located through the plurality of air holes H113 formed in the side surface portion 113 of the main body 11, and the bristle part 110 located in the first space S11 can be dried.
As described above, since the respective bristle parts 110 placed on the brush holder 3 are dried together by the wind flowing in by the rotation operation of the fan 4 in addition to the ultraviolet sterilization by the ultraviolet irradiation unit 21, the bristle parts 110 placed in the first space S11 can be kept clean and hygienic.
The front cover 71 may have a hexahedral shape with both side faces and a rear face open as a cover for covering the front face of the main body 11 of the open casing 1, and the rear cover 72 is a cover for covering the rear face of the main body 11 of the open casing 1.
As shown in fig. 1, the rear cover 72 is located above the motor mounting portion 12 and the power supply mounting portion 13 in addition to the open rear portion of the housing 1, and may be in contact with these upper portions to cover the upper portions of the motor mounting portion 12 and the power supply mounting portion 13.
Thus, such a rear cover 72 may also have a hexahedral shape with both side faces and a rear face open.
However, the front cover 71 and the rear cover 72 have shapes according to the shapes of the opened front and rear surfaces to which they are attached, respectively, and thus may have various shapes.
With such a front cover 71, the first space S11 may be a sealed space having an open lower face and a plurality of air holes H113 at one side (e.g., left side), and with the rear cover 72, the second space S11 may be a space having four sides completely sealed.
In this example, the front cover 71 and the main body 11 may be coupled to each other using grooves (or holes) and protrusions, and for this purpose, protrusions and grooves may be provided at the corresponding portions of the front cover 71 and the main body 11, respectively.
Accordingly, the front cover 71 is opened and closed in the up-down direction centering on the groove or the hole by a force applied by the user.
In contrast, the rear cover 72 may be mounted at the corresponding portion by an adhesive or the like, and the opening and closing action cannot be performed unlike the front cover 71.
Thus, the user opens the front cover 71 in an upward direction to put the toothbrush 100 on the brush holder 3 of the main body 11 or can take out the toothbrush 100 for brushing teeth.
In addition, in order to store the used toothbrush 100 in the toothbrush sterilizer of the present example, the user opens the front cover 71 to put the toothbrush 100 in the toothbrush holder 3, and then operates the driving switch SW1 to sterilize and dry the toothbrush 100.
In accordance with such a user's operation, the driving switch SW1 transmits a signal of this state to the driving module 5, and the driving module 2 can output driving signals to the fan driving part 41 and the ultraviolet irradiation unit 21, respectively.
Thus, the fan 4 rotates in a corresponding direction to allow outside air to enter the inside of the main body 11, and thus the bristle part 110 of the set toothbrush 100 can be dried.
The ultraviolet irradiation unit 21 is turned on to irradiate ultraviolet rays to the bristle sides of the toothbrushes 100 facing each other, and irradiates ultraviolet rays passing through the window WD112 of the rear face 112 of the main body 11 to the bristle 110 side of each toothbrush 100 to perform a sterilizing operation of the toothbrushes 100.
In this case, the operation time of the fan 4 and the respective ultraviolet irradiation units 21 may be set in advance, and thus, if the operation time of the fan 4 and the ultraviolet irradiation units 21 is set, the operation of the fan 4 and the ultraviolet irradiation units 51 may be stopped under the control of the driving module 2 without separate switching operations.
In an alternative example, each ultraviolet irradiation unit 21 is operable in conjunction with the closing operation of the front cover 71 instead of the drive switch SW 1. For this purpose, a sensing portion for sensing the open/close state of the front cover 71 may be provided, and the driving module 2 may output a driving signal to the ultraviolet irradiation unit 21 by using a signal output from such a sensing portion.
The mounting portion 8 may be mounted with the rear cover 72, and may have an attachable or mountable setting tool, such as an adhesive film, on the setting surface of the toothbrush sterilizer, with which the toothbrush sterilizer may be set on a desired setting surface.
In an alternative example, the positions of the motor mounting portion 13 and the power supply mounting portion 14 are interchanged, in which case the second side surface portion 114 where the motor mounting portion 13 is located has a plurality of air holes, and air can be blown from the second side surface portion 114 side to the inner space S11 side.
In addition, unlike the present example, the plurality of windows WD112 may be located at the same height, in which case the plurality of ultraviolet irradiation units 21 corresponding to the respective windows WD112 may also be located at the same height.
Next, referring to fig. 5 to 8, a toothbrush sterilizer according to another embodiment of the present invention will be described.
In the toothbrush sterilizer of the present example, members having the same structure and performing the same function are given the same reference numerals as those of the toothbrush sterilizer of fig. 1 to 4, compared to the toothbrush sterilizer of fig. 1 to 4, and detailed description is omitted.
Referring to fig. 5 to 7, the toothbrush sterilizer of the present example may also have: a housing 1a having a main body 11a, a motor mounting portion 12a, and a power supply mounting portion 13a; a driving module 2a to which a plurality of ultraviolet irradiation units 21 are mounted, the plurality of ultraviolet irradiation units 21 irradiating ultraviolet rays to the inside of the main body 11a of the housing 1 a; a brush holder 3a; a motor 41 located at the motor mounting portion 12a and electrically connected to the driving module 2a; a fan 4a electrically connected to the motor 41; a power supply unit 5 mounted on the power supply mounting unit 13a; a first side cover 61a and a second side cover 62 located on respective sides of the motor mounting portion 12a and the power supply mounting portion 13a; the front cover 71a and the rear cover 72a are respectively located at the open front face and rear face of the main body 11 a; a mounting portion 8a attached to the rear cover 72a; and an upper cover 73 positioned at an upper portion of the main body 11.
The housing 1a of the present example may also have a first space S11 and a second space S12 inside, the first space S11 being located on the front face side and the second space S12 being located on the rear face side.
The main body 11a may also be set based on the shape of the toothbrush sterilizer of the present example, and the main body 11a of the present example may have a substantially hexahedral shape with open front and lower faces.
The main body 11a of the present example has a first space S11 in which the bristle part 110 is placed, and may further have a fan mounting groove P11 in which the fan 4a is provided.
Thus, referring to fig. 6 and 7, the body 11a may have: the upper surface portion 111a, the rear surface portion 112a, the first side surface portion (for example, left side surface portion) 113a, and the second side surface portion (for example, right side surface portion) 114 are different from the rear surface portion 112, the first side surface portion 113, and the second side surface portion 114 of fig. 1 to 3 only in shape, and can actually perform the same function.
Referring to fig. 6 and 7, a portion (first portion) 1c1 of the upper surface portion 111a covers a part of the upper front surface of the main body 111a, and the remaining second portion 1c2 is connected to the first portion 1c1 and can extend to the rear side from a position lower than the first portion 1c 1.
Thus, because of the difference in height between the first portion 1c1 and the second portion 1c2, the inside of the second portion 1c2 of the upper face portion 111a may have a fan mounting groove P11, which fan mounting groove P11 extends in the extending direction of the main body 111a, i.e., laterally.
At this time, a lower portion, for example, a lower middle portion, of the second portion 1c2 of the upper surface portion 111a may have a plurality of air holes H11 in a band shape along the extending direction of the first portion 1c2, and thus the fan mounting groove P11 is provided to be contactable with the plurality of air holes H11.
Thus, the fan 4a of the present example may be located at the upper face 111a of the main body 11a instead of the motor mounting portion 12a, and thus the wind flowing in by the operation of the motor 41 is blown at the upper portion of the main body 11a instead of the side facing the first space S11 side of the housing 1 a.
The rear surface portion 112a may extend downward from the second portion 1c2 of the upper surface portion 111 a.
In this example, the rear surface portion 112a extends substantially from the middle portion of the second portion 1c2 of the front surface portion 111a rather than the distal end to the lower side, and therefore the second space S12 surrounded by the rear portion of the upper surface portion 111a, the motor mounting portion 12a, and the power supply mounting portion 13a can be formed. At this time, the lower portion of the second space S12 may also be blocked by the bottom plate 1c 3. Such a bottom plate 1c3 may constitute a part of the rear face portion 112 a.
Thus, if the rear cover 72 is attached to the housing 1a, the second space S12 in which the driving module 2a is attached can become a space closed by the rear cover 72.
The rear surface portion 112a may have a plurality of windows WD112, and the plurality of windows WD112 expose the respective ultraviolet irradiation units 21 so that the ultraviolet rays outputted from the plurality of ultraviolet irradiation units 21 are outputted forward. The number of windows WD112 may be the same as the number of ultraviolet irradiation units 21.
However, in the toothbrush sterilizer of the present example, the shape and height of each window WD12 may be all the same.
As described above, the height of each window WD12 may be a height corresponding to each bristle portion 110 located on the brush holder 3 a.
The first and second side portions 113a and 114 may be connected to both side ends of the front portion 111a and both side ends of the rear portion 112a, respectively. In this example, the first side surface portion 113a and the second side surface portion 114 may all be a blocked plane.
Thus, the first space S11 can be surrounded by the upper surface 111a, the front portion of the rear surface 112a, the motor mounting portion 12a, and the power supply mounting portion 13 a.
The motor mounting portion 12a may have a hexahedral shape with an open side portion (e.g., left side portion), and as shown in fig. 6 and 7, is attached to the first side portion 113a of the main body 11a, and may extend rearward from the first side portion 113a by a set length.
At this time, the extension length of the motor mounting portion 12a extending rearward from the first side surface portion 113a may exceed the end of the second portion 1c2 of the upper surface portion 111a, but is not limited thereto.
Accordingly, the motor mounting portion 12a may protrude rearward from the rear surface portion 112a of the main body 11a, and the drive switch SW1, the operation display LD1, and the time display LD2 may be provided on the front surface portion 111 a.
Accordingly, the motor 41 and the first driving module portion 2a1 of the driving module 2a may be provided in the motor mounting portion 12a, and the driving module 2a controls the operations of the motor 41, the operation display LD1, and the time display LD 2.
At this time, as shown in fig. 7, the motor mounting portion 12a is a portion of the open rear surface so that the motor 41 mounted on the motor mounting portion 12a can be electrically and physically connected to the fan 4a mounted on the fan mounting groove P11.
The power supply mounting portion 13a is also attached to the second side surface portion 114 of the main body 11a, and may extend rearward from the second side surface portion 114. Accordingly, the power supply mounting portion 13a may also protrude rearward from the rear face portion 112a of the main body 11 a.
At this time, the length of the power supply mounting portion 13a extending rearward of the second side surface portion 114 may exceed the end of the second portion 1c2 of the upper surface portion 111a, but is not limited thereto.
Accordingly, as described above, the second space S12 surrounded by the second portion 1c2 of the upper surface portion 111a, the rear surface portion 112a, the motor mounting portion 12a, and the power supply mounting portion 13c can be formed.
A second driving module part 2a2, i.e., a part of the driving module 2a, may be provided in the second space S12.
The power supply mounting portion 13a may have a mounting hole H13 for mounting the second drive module portion 2a2 in addition to the mounting groove P13 for mounting the power supply portion 5.
Thus, the power supply portion 5 is mounted in the mounting groove P13, and the second driving module portion 2a2 located in the second space S12 can be located in a part of the power supply mounting portion 13a through the mounting hole H13.
As described above, the driving module 2a may have the first driving module part 2a1 and the second driving module part 2a2.
The first driving module portion 2a1 and the second driving module portion 2a2 may be entirely constituted by a printed circuit board, and electronic components and the like necessary for respective operations may be mounted.
The first driving module unit 2a1 is mounted on the motor mounting unit 12a, and is configured to operate the motor 41 to rotate the fan 4a in response to an operation of the driving switch SW1, and to control the lighting states of the operation display LD1 and the time display LD2 provided on the motor mounting unit 12 a.
The second driving module part 2a2 is located in the second space S12 behind the housing 1a, and can control the lighting and lighting-off operation of the ultraviolet irradiation unit 21 attached to itself.
The ultraviolet irradiation units 21 located in the second driving module part 2a2 are provided corresponding to the windows WD112 located in the rear surface 112a of the housing 1a, and can irradiate ultraviolet rays into the first space S11 through the open windows WD 112.
As described above, in the present example, the heights of the respective windows WD112 are the same as each other, and thus the heights of the ultraviolet irradiation units 21 mounted on the second drive module section 2a2 may also be the same as each other.
The brush holder 3a is located between the first side portion 113a and the second side portion 114 of the housing 1a, and may be installed to be in contact with the rear portion 112 a.
The toothbrush holder 3a of the present example may be a plate having a set width and elongated in an extending direction (e.g., a lateral direction), and may have a plurality of toothbrush insertion grooves H31 to H34 along the extending direction.
At this time, the heights of the plurality of toothbrush insertion grooves H31-H34 may be the same as each other, and thus the heights of the bristle parts 110 of the toothbrushes 110 inserted into the toothbrush insertion grooves H31-H34 of the toothbrush holder 3a of the present example may be the same or similar as shown in FIG. 8.
However, as described above, the fan 4a is located in the fan mounting groove P11, and the fan mounting groove P11 is located at the upper portion of the bristle part 110, that is, the upper surface portion 111a of the main body 11a.
Thus, the toothbrush sterilizer of the present example can blow air from the upper portion of the main body 11 to the lower side, i.e., the first space S11 side of the main body 11, as compared to the toothbrush sterilizer of fig. 1 to 4 which blow air from one side surface portion of the main body to the other side surface portion, i.e., the first space S11 side.
Accordingly, air is uniformly blown to all the bristle parts 110 located at the same or similar height in the first space S11, and thus, even if the bristle parts 110 are overlapped in the horizontal direction, stable drying operation can be performed to all the bristle parts 110.
The motor 41 mounted on the motor mounting portion 12a is physically connected to the fan 4a located in the fan mounting groove P11, and further, the rotation operation of the fan 4a can be controlled.
The driving time of the motor 41 may be set in advance, and the fan 4 may be rotated for a set time each time the driving switch SW1 is operated.
As shown in fig. 2 and 3, the fan 4a of the fan installation groove P11 located at the upper portion of the main body 11 may be a cross flow fan having a laid down elliptical shape, such as a cylinder shape, instead of a fan having a rotary fin protruding to the outside.
Accordingly, the fan 4a is positioned in the fan mounting groove P11 formed in the upper surface portion 111a so as to extend in the extending direction of the main body 11a, and the air can be blown downward uniformly regardless of the position by the air blowing port positioned in the predetermined section in the extending direction of the fan 4 a.
Therefore, the drying operation can be effectively performed on a plurality of toothbrushes without increasing the size of the toothbrush sterilizer.
For example, in the case of using toothbrush holders having stepped shapes with different heights, as the number of steps increases, the size of the toothbrush sterilizer increases in the up-down direction in addition to the extending direction.
However, in the case of the toothbrush sterilizer of the present example, the size of the toothbrush 100 in the vertical direction is not increased, but only the size in the extending direction is increased to greatly increase the number of toothbrushes 100, and the air can be uniformly blown to the respective bristle parts 110, so that the drying time of the respective bristle parts 110 can be greatly shortened.
The power supply portion 5 located in the mounting groove P13 of the power supply mounting portion 13a serves as a battery, and supplies power to components necessary for the operation of the toothbrush sterilizer, such as the first and second driving module portions 2a1 and 2, the motor 41, the driving switch SW1, and the displays LD1 and LD 2.
The first side cover 61a and the second side cover 62 are covers that cover the open side surfaces of the power supply mounting portion 13a of the motor mounting portion 12a, respectively.
As described above, the fan 4a injecting air into the inside of the main body 11a is located at the upper portion of the main body 11a, and thus no ventilation hole may be present in the first side cover 61a of the present example, the first side cover 61a being mounted on the motor mounting portion 12a, the motor mounting portion 12a being mounted with the motor 41.
The front cover 71a and the rear cover 72a are respectively mounted on the corresponding portions of the body 11a, and thus can cover the front and rear faces of the opened body 11a.
When compared with the front cover 71 of fig. 1 to 3, the front cover 71a is only different in shape, and can perform the same function.
Thus, the front cover 71a is openably mounted on the upper face 111a of the main body 11a by a user.
Further, the ultraviolet radiation device further includes a sensing unit for sensing the opening/closing state of the front cover 71a, and the on/off state of the ultraviolet radiation unit 21 can be controlled based on the sensing state of the sensing unit.
The rear cover 72a may have a shape of inverted "ㄈ", with the front face portion and the left and right side face portions being open, and having an upper face portion 721, a rear face portion 722, and a lower face portion 723. Therefore, the rear surface of the main body 11a can be covered by the motor mounting portion 12a and the power source mounting portion 13a.
As described above, the rear cover 72a is located above the motor mounting portion 12a and the power supply mounting portion 13a in addition to the open rear portion of the housing 1a, and can be provided in contact with these upper portions, so that the upper portion 721 of the rear cover 72a can cover the motor mounting portion 12a and the power supply mounting portion 13a.
The upper surface 721 of the rear cover 72a is positioned on the second portion 1c2 of the upper surface 111a of the main body 11a, and may be overlapped with the second portion 1c2.
Thus, the open upper portion of the fan mounting groove P11 is covered by the upper face 721 of the rear cover 72a, and the second space S12 may also be closed by the rear cover 72 a.
At this time, in the upper portion of the fan 4a located in the fan mounting groove P11, a plurality of ventilation holes H72 may be provided in the upper face 721 of the rear cover 72a facing the fan 4 a.
The plurality of ventilation holes H72 are located on the plurality of ventilation holes H11 so as to face the plurality of ventilation holes H11, and the plurality of ventilation holes H11 are located on the second portion 1c2 of the upper surface portion 111a of the main body 11 a. Therefore, the plurality of ventilation holes H72 and the plurality of ventilation holes H11 can overlap each other in the vertical direction.
Accordingly, the wind entering through the plurality of ventilation holes H72 can be rapidly blown into the first space S11 through the plurality of ventilation holes H11 located at the lower portion.
Each ventilation hole H72 may have a planar shape such as a quadrangle, and is elongated in a direction along which the width of the upper surface 721 of the rear cover 72a is elongated, i.e., in the width direction (for example, the longitudinal direction) into a straight line or a diagonal line.
As described above, the plurality of ventilation holes H72 are located on the fan 4a mounted in the fan mounting groove P11 instead of the first side surface portion 113a, so that the outside air is stably blown into the fan mounting groove P11 through the ventilation holes H72 according to the operation of the fan 4a, and then enters the first space S11 in the main body 11a, and thus the air can be smoothly circulated.

However, the mounting portion 8a is positioned on the upper surface portion 721 of the rear cover 72a so as to overlap the upper surface portion 721 in order to function as a top cover for the plurality of ventilation holes H72a, and further, can completely cover the plurality of ventilation holes H72 positioned on the upper surface portion 721.
In this way, the plurality of ventilation holes H72 are completely covered by the upper surface 81 of the mounting portion 8a, so that it is possible to prevent contaminants such as water and dust falling from the upper side of the toothbrush sterilizer from entering the plurality of ventilation holes H72.
As described above, the mounting portion 8a has a setting means such as the adhesive film 84 to set the toothbrush sterilizer at the setting surface, and is associatively mounted to the rear cover 72a using magnetic force or the like.
In the respective embodiments of the present invention, the housing 11, 11a has a plurality of windows WD112 and a plurality of ultraviolet irradiation units 21 corresponding to the respective windows WD 112.
However, in an alternative example, the number of windows WD112 is one, and at least one ultraviolet irradiation unit 21 may be provided corresponding to the open windows WD 112. At this time, one window WD112 may have the same height or a stepped shape regardless of the position.
In other alternative examples, there may be a plurality of windows WD112 in one ultraviolet irradiation unit 21, and each window WD112 may be provided corresponding to the bristle section 110 of the toothbrush 100 placed in the brush holder 3, 3 a.
