Description

Smell remover

Technical Field

The utility model relates to a deodorizer, in particular to a deodorizer which comprises an anion generator and can accommodate air fresh material bags.

Background

With the improvement of living standard, people put higher requirements on air purification under the conditions of families, work, trips and the like. Due to air pollution, daily decoration, and problems of automobiles and household appliances, various unpleasant and harmful odors or odors are often generated in rooms, toilets, vehicles, and refrigerators. In order to remove such odor or bad smell, various air purification techniques such as physical filter screen, ozone, deodorizing catalyst, negative ion, etc. are used in the prior art.

The most common air purification technique is to use a fan to draw air and use a physical filter screen to filter tiny particles in the air to purify the air. However, such physical filters need to be replaced periodically and good filters are expensive.

The other air purifying technology is to use an ozone generator to generate ozone, and to oxidize harmful components in the air by using the strong oxidizing property of the ozone, so as to achieve the purpose of purifying the air. However, ozone itself is harmful to human body, and if more ozone is discharged into the air, it can cause poisoning.

Still another air purification technique employs a deodorizing catalyst, typically involving noble metals such as palladium, platinum, and the like. However, this solution is expensive, has a poor deodorizing effect, and is easily deteriorated and saturated.

Compared with the above technology, the anion air purifier is a more ideal choice. The negative ions generated by the negative ion generator can be used for dedusting, deodorizing and sterilizing air, and actively capturing harmful substances in the air (most of odor, peculiar smell, bacteria, smoke particles and the like in the air are provided with positive charges, so that the negative ions can be neutralized with the odor, the peculiar smell, the bacteria, the smoke particles and the like) without frequently replacing consumables. However, the negative ion air cleaner may generate a small amount of ozone while generating negative ions due to its own mechanism.

Therefore, there is a need for further improvement in the related art air purifier or deodorizer to purify air more effectively and enrich its function.

Referring to fig. 9, the annular light guide plate 4 is arranged around the air guide mesh enclosure 3 and includes an annular body 41, a central opening 42, and a rectangular tab 43 extending rearward from a rear edge of the annular body 41, the annular body 41 being provided with an annular projection 45 for surrounding and contacting the air guide mesh enclosure 3. On the rear edge of the rectangular tab 43, there is provided a rectangular strip-like projection 44 projecting upward and downward, the two rectangular strip-like projections 44 extending in the lateral direction perpendicular to the front-rear direction and serving together as a light incident portion 48 of the annular light guide plate 4. As described later, the light of the row of light source LEDs 87 vertically arranged on the rear surface of the PCB control board 86 in the second accommodation area 22 will be incident from this light incident portion 48 into the annular light guide plate 4, the light traveling within the annular light guide plate 4 to form the illumination ring or the light emitting ring 45 around the air guide mesh enclosure 3, that is, in this case, the annular projection 45 of the light guide plate 4 arranged around the air guide mesh enclosure 3 appears as the illumination ring or the light emitting ring 45.

An annular resting portion (fig. 9) slightly recessed from the top surface thereof is provided on the inner periphery of the annular body 41 for placing the air guiding mesh enclosure 3. Four corners of the ring body 41 are provided with four screw holes (i.e., two first screw holes 46 at the front edge and two second screw holes 47 at the rear edge) for fastening the ring-shaped light guide plate 4 to the bottom case 2 and the top case 1 by screws.

The control device of the deodorizer of the present invention is described below. The control device includes a PCB control board 86 (fig. 8) vertically accommodated in the second accommodation region 22, the PCB control board 86 being provided with various electronic components such as a microprocessor, a chip resistor, a chip capacitor, a chip MOS transistor, a chip diode, a chip triode, a chip key, and the like on a front surface, and a row of light source LEDs 87 horizontally arranged on a rear surface, the light source LEDs 87 serving as incident light sources of the ring-shaped light guide plate 4 and being adjacent to the light incident portion 48 of the ring-shaped light guide plate 4, incident light from the light source LEDs 87 being incident to the light incident portion 48 and traveling within the ring-shaped light guide plate 4, thereby being capable of forming an illumination ring or a light emitting ring 45 around the air guide mesh enclosure 3 when energized. The microprocessor, the chip resistor, the chip capacitor, the chip MOS transistor, the chip diode, the chip transistor, the chip button, and the LED are well known to those skilled in the art, and will not be described in detail herein.

As best shown in fig. 2 and 4, the control device also includes three function switches 81, 82 and 83, which may be function buttons or control buttons, such as an anion switch 81 on the right side of the figure, a middle fan switch 82, and a sleep mode switch 83 (also referred to as a night light mode switch) on the left side, and an LED-based fan speed indicator 84.

Referring to the above and fig. 2 and 9, the three function switches 81, 82 and 83 are mounted to the three circular apertures 25 on the rear wall of the bottom case 2 by three transparent or translucent button mounting rings (not shown) made of PC material, respectively, and will cooperate with the three patch keys on the front face of the PCB control board 86 to control the ionizer 6, the fan 7 and the LEDs for the sleep mode, respectively. Around these three function switches 81, 82 and 83, an indicator light ring 85 can be arranged for each function switch 81, 82 and 83. The indicator light ring 85 may be formed of a translucent light guide post made of a PC material arranged around the function switches 81, 82, and 83. Similar to the principle of the annular light guide plate 4, when light of the corresponding LED is incident to the light guide lamp post, the light will travel within the light guide lamp post and form an indicator lamp ring 85 around each of the function switches 81, 82 and 83, thereby enabling indication of the operating state of the respective function switches 81, 82 and 83.

As shown in fig. 2 and 4, the LED fan speed indicator 84 includes three LED indicator lights for indicating the rotation speed of the fan 7, for example, four speeds (0-3) are provided, which correspond to a strong wind screen, a medium wind screen, a weak wind screen, and a power off. Different gears can light different numbers of indicator lamps, for example, three LED indicator lamps are simultaneously turned on to indicate a strong windshield, two LED indicator lamps are simultaneously turned on to indicate a medium windshield, only one LED indicator lamp is turned on to indicate a weak windshield, and three LED indicator lamps are completely turned off to indicate that the fan 7 is turned off.

The power supply device of the deodorizer of the present invention is described below. The power supply device includes a PCB power board (not shown) provided with components for various voltage conversions, such as a chip rectifier bridge, a chip resistor, an electrolytic capacitor, a rectifier diode, a high frequency transformer, etc., which are accommodated in the second accommodation area 22. The power strip can receive alternating current (e.g. 110V or 220V) in the range of 100V-240V and convert it to, for example, 5V output voltage to power the PCB control board, the ionizer 6, the fan 7. These are well known to those of ordinary skill in the art and will not be described in detail herein.

As shown in fig. 3, 7 and 8, the power supply device further includes a power plug provided at the bottom case 2, which is a replaceable power plug and has a body 91 and pins 92. Triangular alignment indicators 93 are provided on the body 91 and the power supply unit accommodating portion 26 of the bottom case 2, respectively. When the two alignment indicators 93 are aligned with each other, it indicates that the body 91 of the power plug has been mounted in place in the power supply unit accommodating portion 26 of the bottom case 2. Specifically, referring to fig. 8 and 9, the bottom surface of the power supply device accommodating portion 26 of the bottom case 2 may be provided with one or more arc-shaped grooves 261, for example, two arc-shaped grooves spaced 180 degrees apart from each other in the circumferential direction. One or more annular protrusions 94 corresponding to the arc-shaped grooves 261 may be provided on the upper surface of the body 91. The annular projection 94 can be inserted into the arcuate slot 261 and rotated by hand through an angle to align the two alignment indicators 93 with each other.

The assembly of the deodorizer of the present invention is described below.

First, the PCB power supply board of the power supply device is disposed in the second receiving area 22 of the bottom chassis 2, and the lower end of the PCB control board 86 of the control device is vertically inserted into the PCB receiving portion 28 of the bottom chassis 2 from above. Three function switches 81, 82 and 83 are mounted into the three circular apertures 25 on the rear wall of the bottom case 2 by the button mounting rings (not shown) described above and are electrically connected to the PCB control board 86 and the PCB power board, respectively. The three LED indicator lights of the LED fan speed indicator 84 are also electrically connected to the PCB control board 86 and the PCB power board. Then, the ionizer 6 and the fan 7 are placed in the first accommodation area 21 of the bottom case 2 and are also electrically connected to the PCB control board 86 and the PCB power board. Note here that the vertical position of the ionizer 6 with respect to the fan 7 may be different from that in fig. 8, and may be slightly shifted upward from the position in fig. 8, for example.

Then, the air guiding mesh enclosure 3 is placed in the annular rest portion of the annular light guide plate 4 from above and pressed downward, so that the four hooks 32 of the air guiding mesh enclosure 3 extending downward from the front edge, the rear edge, the left edge, and the right edge of the body 31 are snapped into the four notches 49 of the annular light guide plate 4 as described earlier and hook the bottom surface of the annular light guide plate 4 (see fig. 8, 9). Thereby, the air guide mesh enclosure 3 and the annular light guide plate 4 are assembled and fixed together.

Then, the two first screw holes 46 of the ring-shaped light guide plate 4 are aligned with and connected to the two first support posts at the front of the top case 1, and the two second screw holes 47 of the ring-shaped light guide plate 4 are aligned with and connected to the two second support posts 15 of the top case 1. Thus, the assembly composed of the air guide mesh 3 and the annular light guide plate 4 is fixed to the top case 1 together. In this state, the light incident portion 48 of the annular light guide plate 4 is adjacent to and substantially between the two PCB receipt portions of the top case 1 in the lateral direction.

Then, the top case 1 is placed over the bottom case 2 with the continuous annular groove 14 on the bottom surface of the top case 1 aligned with the annular continuous projection 24 on the top surface of the bottom case 2, and the projection 24 is inserted into the groove 14 by pressing down, thereby preliminarily fixing the top case 1 and the bottom case 2 together. At this time, the central screw holes of the two first supports 23 of the bottom case 2 at the front are aligned with the central screw holes 46 of the ring-shaped light guide plate 4 and the central screw holes of the two first supports of the top case 1 at the front, and the central screw holes of the two first supports 23 of the bottom case 2 at the rear are aligned with the central screw holes of the two first supports of the top case 1 at the rear. Therefore, four screws may be screwed into these screw holes from below the bottom surface of the bottom case 2, thereby completely fixing the top case 1 and the bottom case 2 together. In this state, referring to fig. 8, the fan 7 and the ionizer 6 are disposed in the air flow passage 10. The annular light guide plate 4 and the air guide mesh enclosure 3 are on top of the fan 7 with sufficient clearance left therebetween to facilitate rotation of the blades of the fan 7. The ring-shaped light guide plate 4 is at the top surface of the bottom chassis 2, and the light incident parts 48 of the rectangular tabs 43 of the ring-shaped light guide plate 4 are adjacent to and at substantially the same height as the row of light source LEDs 87 of the PCB control board 86, so that the light incident parts 48 receive incident light from the light source LEDs 87. The top case 1 downwardly presses the periphery of the annular light guide plate 4 and the periphery of the air guide net 3, and the air guide net 3, the grip bracket 11 and the four walls of the top case 1 together define a charcoal pack/perfume pack accommodating portion in the form of a basin, so that the air freshener pack 20 can be placed in the charcoal pack/perfume pack accommodating portion and gripped between the grip bracket 11 and the air guide net 3.

Then, the power plug is inserted into the power supply device receiving portion 26 of the bottom case 2. In the case where the power plug is a replaceable power plug, the replaceable power plug may be rotatably connected to the power supply device receiving portion 26 of the bottom case 2. Specifically, the annular projection 94 (fig. 8) of the body 91 of the power plug is inserted into the arc-shaped groove 261 of the power supply device accommodating portion 26 of the bottom case 2 and rotated by hand by a certain angle until the two alignment indicators 93 are aligned with each other.

Finally, the decorative sheet 5 is fitted into the decorative sheet accommodating recess 12 of the holding bracket 11. Specifically, the hook portion of the decorative sheet 5 as described above is inserted into the groove 17 with the hook portion (fig. 8) of the clip bracket 11 and the two hook portions are engaged with each other (fig. 8). The assembly of the deodorizer is now complete. The user may then selectively place the cartridge/flavor pack 20 (i.e., the "air freshener cartridge") in the cartridge/flavor pack receptacle of the deodorizer, as desired by the user.

It can be seen that the holding bracket 11 serves primarily to receive an air freshener bag or charcoal/perfume bag 20, so that it can be arranged at the air outlet 104 of the air flow channel 10, in particular it can be held between the holding bracket and the air deflection screen 3.

The working principle and process of the deodorizer of the present invention are described below.

The deodorizer operates when a power plug is plugged into a 110V or 220V power outlet on a wall, for example. In operation, external air can be drawn into the air flow passage 10 from the air inlet (including the air inlet 102 in the bottom surface and the air inlet 103 in the side surface) of the air flow passage 10 within the main body of the deodorizer by the fan 7. The air drawn in from the air inlets 102,103 of the air flow channel 10 then flows through the ionizer 6, the fan 7 disposed in the air flow channel 10, and finally passes through the charcoal pack/perfume pack 20 in this order.

More specifically, external air is drawn into the air flow passage 10 from a grill-like air inlet 102 (see fig. 7, which is similar in shape to the air guide net 3) at the front of the bottom surface of the bottom case 2 and side air inlets 103 at the front of the front surface and both side surfaces of the bottom case 2. Then, the air passes through the negative ion generator 6, and the negative ion generator 6 can generate ≧ 300 ten thousand/cm³As mentioned above, these negative ions can neutralize the odor, bacteria, smoke particles, etc. in the air, and primarily purify and deodorize the air. The air then passes through the fan 7 to and through the elongate gaps between adjacent grills of the body 31 of the air guiding net 3. Finally, the space isThe air passes through the charcoal bag/perfume bag 20 disposed above the air guide net cover 3 at the air outlet 104 and accommodated in the charcoal bag/perfume bag accommodating part, thereby adsorbing peculiar smell, odor and harmful gas in the air by using the carbon particles/air freshener in the charcoal bag/perfume bag 20 to secondarily purify and deodorize the air.

Referring to fig. 2 and 4, the fan 7 has four states of strong damper, medium damper, weak damper, and off, and the fan switch 82 and the anion switch 81 are turned on simultaneously at the factory or by default, and the fan 7 is in strong damper and provides an air flow of, for example, 12CFM (cubic feet per minute) to maximize air purification using the charcoal pack/spice pack 20 and the anion generator 6 simultaneously. Of course, the fan state may also be adjusted to take the appropriate gear depending on the particular application. For example, one fan gear may be shifted per press of fan switch 82, thereby switching from a high wind gear to a medium gear (e.g., 9CFM airflow), a low wind gear (e.g., 6CFM airflow), or a shut down state. At the same time as each switch, a corresponding number of LED indicator lights of the LED fan speed indicator 84 are illuminated to indicate the current fan gear or current operating condition.

When the fan 7 is turned on, the operation state of the ionizer switch 81 is switched every time the ionizer switch 81 is pressed, for example, the ionizer switch 81 is switched from the on state to the off state or from the off state to the on state. Therefore, in the state where the fan 7 is turned on, the ionizer 6 can be turned off so as to adsorb the bad smell, and the harmful gas in the air only by the charcoal pack/perfume pack 20. When the fan 7 is turned off (for example, when absolute silence is required, noise of the fan 7 may cause interference), the ionizer 6 may be turned off or may be in an operating state, that is, the ionizer 6 may be operated alone with the fan 7 turned off, so as to remove odor, bacteria, smoke particles, etc. from the air by using the negative ions generated by the ionizer 6. Therefore, the fan 7 and the ionizer 6 can be operated at the same time to improve the purifying effect, and only one of them can be turned on according to the situation.

When the sleep mode switch 83 is pressed in the operating state, the sleep mode can be turned on or off (the state of the sleep mode switch 83 is switched every time it is pressed). After entering the sleep mode, only the indicator light of the sleep mode switch 83 is retained and all other indicator lights are turned off. The fan 7 is turned to a weak windshield or turned off to reduce noise, and the working state of the ionizer 6 is not affected. In the sleep mode, when any one of the ionizer switch 81, the fan switch 82, and the sleep mode switch 83 is pressed, the sleep mode is released and the previous operation state is restored.

In addition, a timer may be provided on the PCB control board 86 to provide an on-duty timing function. For example, the fan 7 may be set on for about 30 days in a timer, and when the time reaches 30 days, a warning light (not shown) is illuminated to prompt replacement of the charcoal/spice bag 20. If no replacement is desired, fan switch 82 may be pressed, for example, for a long time of 2 seconds to clear the alarm and start a new cycle of timing from scratch.

In addition, a power-down memory device may be provided on the PCB control board 86 to provide a power-down memory function so as to continue the previous operation mode and operation timing in case of power restoration after power failure or careless power failure.

Modified embodiment

In addition to the above embodiments, the present invention may have the following modified embodiments:

1) although the power plug is shown in the drawings as being swivel mounted, this need not be the case. For example, it may also be directly insertable, so as to be directly inserted into the bottom shell 2. Also, although the pin 92 is shown in the drawings as a round euro pin, this need not be the case. For example, it may also be the most common flat shape of the American-style pin.

2) Although the alignment indicators 93 are shown as triangular in the drawings, this is not necessarily so. It may also be other suitable shapes such as arrows, dots, rectangles, trapezoids, straight lines, etc. Of course, the alignment indicator 93 may also be omitted. In this case, an internal stop may be provided to achieve a similar function.

3) Although shown as two separate components in the top and bottom shells 1, 2, this need not be the case. For example, they may be integral.

4) Although the function switches 81, 82 and 83 are shown in the figures as being in the circular aperture 25 of the rear wall of the bottom shell 2, this is not necessarily the case. For example, these function switches 81, 82 and 83 and the aperture 25 may also be provided in the front wall or side wall of the bottom case 2 or in the wall of the top case 1. Also, the arrangement order of the function switches 81, 82, and 83 may be different from that shown in the drawing.

5) Although the air guide mesh enclosure 3, the annular light guide plate 4, the decorative sheet 5, and the holding bracket 11 are shown in the drawings, their shapes and structures may be different from those shown in the drawings as long as their respective functions are achieved. Further, these components may even be omitted.

6) Although the annular groove 14 of the top shell 1 and the annular projection 24 of the bottom shell 2 are shown as continuous in the figures, this is not necessarily the case. For example, they may each be composed of a plurality of discrete portions.

7) Although the air inlet is shown in the drawings as being provided on the bottom surface and the side of the bottom case 2, it is not necessarily so. For example, air may be admitted from above or from any side, as desired.

8) Although the charcoal/fragrance packet 20 is shown in fig. 10 as a charcoal packet, it may also be other fragrance packets or fragrances, such as pacific flax, fresh grapefruit, soothing lavender, pet soothing agents, and the like. The contents may also be liquid rather than solid particles.

9) Although the deodorizer is powered by an external power supply, the deodorizer can be powered by an internal battery without a power plug. In addition, the power plug can be changed into a USB interface or other types of power interfaces to adapt to the occasions of low-voltage application (such as 5V, 12V and 24V).

Various embodiments of the present invention have been described in detail above with reference to the accompanying drawings. It will be understood that various modifications and changes may be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims, all of which are intended to be included within the scope of the invention.
