Referring to fig. 3 specifically, in order to enable the airflow flowing into the second gap 40 and the airflow flowing into the third gap 50 to more quickly change from the original airflow flowing into the tail end of the air duct 1 to the head end of the air duct 1, and finally flow out of the head end of the air duct 1 sequentially through the inner cavity of the first duct 12 and the inner cavity of the first duct body 11, in this embodiment, the dust removing device 100 further includes a first auxiliary guide member 60 disposed in the air duct 1, the outer diameter of the first auxiliary guide member 60 gradually converges from one end near the tail end of the air duct 1 to one end near the head end of the air duct 1, and the bottom surface of one end (i.e. the converging end) of the first auxiliary guide member 60 near the tail end of the air duct 1 is connected with the tail end of the air duct 1, so that the airflow flowing into the second gap 40 and the airflow flowing into the third gap 50 flow to the tail end of the air duct 1 more quickly turn to the front end of the air duct 1 under the stop action of the outer wall surface of the first auxiliary guide member 60.
Referring to fig. 1 and 3, in order to make the blowing function of the dust removing apparatus 100 better, it is necessary to properly enhance the blowing function of the dust removing apparatus 100, i.e. reduce the opening size of the first air duct body 11, in this embodiment, the dust removing apparatus 100 further includes a second auxiliary guide 111 disposed at one end of the first air duct body 11 near the end of the air duct 1, and the outer diameter of the second auxiliary guide 111 gradually converges from one end near the end of the air duct 1 to one end far from the end of the air duct 1.
Referring to fig. 1 and fig. 3, in order to make the air suction function of the dust removal device 100 better, the air suction function of the dust removal device 100 can be properly enhanced, i.e. the opening size of the second air duct body 21 is increased, in this embodiment, the dust removal device 100 further includes a third auxiliary guide 211 disposed at one end of the second air duct body 21 near the head end of the air duct 1, and the outer diameter of the third auxiliary guide 211 gradually expands from one end near the head end of the air duct 1 to one end far from the head end of the air duct 1.
Referring to fig. 1 and fig. 2, since the surface of the object to be cleaned has relatively firm adsorption of the impurities such as the fimbriae and the dust, the dust removing effect may not be good due to the blowing air flow and the suction air flow of the dust removing device 100, in order to make the dust removing effect of the dust removing device 100 better, in this embodiment, the dust removing device 100 further includes a first brush 112 disposed at the end of the second auxiliary guide 111 far from the head end of the air duct 1, and a second brush 212 disposed at the end of the third auxiliary guide 211 far from the head end of the air duct 1. Of course, in other embodiments, the first brush 112 and the second brush 212 may be added alternatively.
It should be noted that, first, when the dust removing device 100 works, the first brush 112 and the second brush 212 can disturb the sundries on the surface of the article, and cooperate with the disturbing effect of the blowing air flow and the absorbing effect of the air suction air flow to clean and tidy the sundries on the surface of the article together, so as to effectively improve the dust removing effect of the dust removing device 100. Meanwhile, in order to avoid the contact mechanical damage that the first brush 112 and the second brush 212 may have to be caused to the articles, the bristles of the first brush 112 and the second brush 212 may be made of ultra-soft antistatic artificial fiber bristle material capable of directly contacting the skin of the human body.
Second, referring to fig. 1 specifically, in the present embodiment, the first brush 112 is a brush having a cross shape including a brush body and bristles, so as to more conform to the action habit of the wrist of the human body when swinging, thereby improving the dust disturbance efficiency and the controllability of the manual operation. Meanwhile, as the first air duct body 11 is arranged at the center of the air duct 1, sundries can be reduced from adhering to the first hairbrush 112. The cross-shaped brush may be integrally formed or may be formed by splicing and fixing two straight-line brushes, however, in other embodiments, the first brush 112 may be a "m" shaped brush formed by splicing and fixing a plurality of straight-line brushes, provided that the first air duct body 11 or the second auxiliary guide member 111 cannot be excessively blocked, so as to avoid excessively weakening the blowing function of the dust removing device 100.
Third, referring to fig. 3 in detail, the second brush 212 is an annular brush including a brush body and bristles, and the bristles of the first brush 112 are slightly longer than the bristles of the second brush 212, so that the second brush 212 can function to block the dust escaping and spreading caused by the air blowing flow of the dust removing device 100 and the disturbance of the first brush 112 when the first brush 112 is in a curved working state. Wherein, the brush bodies of the first brush 112 and the second brush 212 can be detachably connected with the third auxiliary guide 211 by means of a buckle, a thread, etc., so that the brush can be selectively added or removed according to the actual situation when cleaning the objects.
Referring to fig. 1, in order to further see the impurities on the surface of the object, to avoid damaging the fragile object or cleaning the object in place in the dark, in this embodiment, the dust removing device 100 further includes an illumination lamp 213 disposed at an end of the third auxiliary guide 211 far from the head end of the air duct 1. Of course, in other embodiments, the illumination lamp 213 may be disposed at other positions of the dust removing device 100, such as the end of the second auxiliary guide 111, the air duct 1, or the handle 8, but the end of the third auxiliary guide 211 can obtain a larger and better illumination effect without affecting the dust removing function.
It should be noted that, compared with the manner of adding other lighting tools such as a flashlight, the manner of directly adding the lighting lamp 213 to the dust removing device 100 can further liberate the hands of the operator, so that the operator can leave the hands free for other tasks. The illumination lamp 213 may be an LED (chinese full name: light emitting diode, english full name: light Emitting Diode) lamp, so that the dust removing device 100 is more energy-saving and environment-friendly.
Referring to fig. 3 specifically, in order to achieve a filtering function for impurities in the external environment sucked into the dust removing device 100 through the third gap 50, the air flow containing impurities sucked from the third gap 50 can be changed into a clean air flow, so as to avoid secondary suspension pollution of dust particles caused by scattering of impurities such as dust around and possible adverse effects on the health of operators, in this embodiment, the dust removing device 100 further includes a filtering device 70 disposed in the air duct 1, and the first air duct assembly 10 is connected to the tail end of the air duct 1 through the filtering device 70, so that the air flow flowing into the third gap 50 flows out of the head end of the air duct 1 through the third filtering layer 73, the second filtering layer 72, the first filtering layer 71, the inner cavity of the first air duct 12 and the inner cavity of the first air duct body 11, so as to avoid the impurities flowing out of the head end of the air duct 1 along with the air flow flowing into the third gap 50, so as to avoid the pollution to the surrounding air when the dust removing objects are removed by the dust removing device 100, prevent the operators from sucking the impurities blown up through the air duct 100, and to protect the health and safety of operators.
In order to further improve the filtering effect, in this embodiment, the filtering device 70 includes a first filtering layer 71, a second filtering layer 72, and a third filtering layer 73 that are sequentially disposed from the head end of the air duct 1 to the tail end of the air duct 1, where the first filtering layer 71, the second filtering layer 72, and the third filtering layer 73 are three filtering boxes that are sequentially connected, and the filtering boxes include a box body and a filter screen that is disposed in the box body, and the filtering boxes can be detached and replaced to ensure the normal filtering function of the dust removing device 100. Of course, in other embodiments, the filter device 70 may further include more filter layers, and three filter layers are preferably provided here in consideration of the size and weight of the dust removing device 100 and the filtering effect.
The air flow sucked through the third gap 50 flows from the tail end of the air duct 1 to the front end of the air duct 1 under the action of the second guide duct 22 and the first auxiliary guide 60, so that the filter mesh sizes of the first filter layer 71, the second filter layer 72 and the third filter layer 73 can be different along the outflow direction of the air flow flowing into the third gap 50, so that each filter layer can effectively aim at sundries with different particle sizes. Specifically, in the present embodiment, the screen aperture of the first filter layer 71, the screen aperture of the second filter layer 72, and the screen aperture of the third filter layer 73 are sequentially increased. By such arrangement, the first filter layer 71 can be directed against microorganisms having the smallest particle diameter, the second filter layer 72 can be directed against fine dust having a medium particle diameter, and the third filter layer 73 can be directed against coarse dust having a larger particle diameter. Wherein, because of the specificity of cultural relics, the filter layer after use can be collected intensively to sterilize the adsorbed microorganisms.
Of course, in other embodiments, the filter apertures of the three filter layers may be all the same or two by two according to practical situations, for example, the filter aperture of the first filter layer 71 and the filter aperture of the second filter layer 72 are the same, and are both smaller apertures, and the filter aperture of the third filter layer 73 is larger, or the filter aperture of the first filter layer 71 is smaller, and the filter aperture of the second filter layer 72 and the filter aperture of the third filter layer 73 are the same, and are both larger apertures.
In this embodiment, the dust removing device 100 further includes a controller, a power supply device 84 and a fan 85, which are disposed in the handle 8, where an air outlet of the fan 85 is communicated with the main air duct 80, the power supply device 84 is electrically connected with the controller, and an output end of the power supply device 84 is connected with an input end of the fan 85, and is used to drive the fan 85 to start and stop according to a first control signal of the controller. The power supply device 84 may be a storage battery, which has the advantages of convenient assembly and disassembly and repeated charging. Of course, in other embodiments, the power supply 84 may also use an external power source or use both a battery and an external power source.
In this embodiment, a first valve 86 is disposed at a connection position between the first branch 81 and the main air duct 80, the first valve 86 is electrically connected to the controller, and is configured to control opening and closing of the first valve 86 according to a second control signal of the controller, a second valve 87 is disposed at a connection position between the second branch 82 and the main air duct 80, and the second valve 87 is electrically connected to the controller, and is configured to control opening and closing of the second valve 87 according to a third control signal of the controller, so that the first branch 81 and the second branch 82 of the dust removing device 100 can be selectively opened and closed, that is, the first valve 86 and the second valve 87 are both in an opened state, or the first valve 86 is in a closed state and the second valve 87 is in an opened state. Wherein, the first valve 86 and the second valve 87 are both solenoid valves.
For example, when the first valve 86 is closed and the second valve 87 is opened, the air flow flowing out of the main air duct 80 flows into the second gap 40, the air flow flowing into the second gap 40 is firstly directed to the tail end of the air duct 1, and negative pressure is formed at the tail end of the air duct 1, so that the air flow with lighter external environment or object surface quality is firstly sucked into the dust removing device 100 through the third gap 50, and although the air flow flowing into the second gap 40 is blown out through the inner cavity of the first guide pipe 12 and the inner cavity of the first air duct body 11 after the tail end of the air duct 1 is turned, the suction and the blowing have a certain time difference, so that the problem that the air flow directly flowing out of the main air duct 80 through the first branch 81 and the inner cavity of the first air duct body 11 blows out the air flow with lighter weight in the main air duct 80 when the first valve 86 is simultaneously opened can be avoided, and the negative pressure formed at the tail end of the air duct 1 is not easy to suck.
It should be noted that, the above selective opening and closing of the first branch 81 and the second branch 82 does not include the case that the first valve 86 is in the open state and the second valve 87 is in the closed state, that is, only when the controller controls the second valve 87 to open, the first valve 86 can be opened, so as to avoid the phenomenon that the dust removing device 100 only blows out and does not suck.
In order to accurately control the sizes of the blowing air flow and the suction air flow, dust with different specific gravities can be removed conveniently, in this embodiment, the dust removing device 100 further includes an adjusting knob electrically connected to the controller, and the adjusting knob is used for adjusting the opening and closing degrees of the first valve 86 and the second valve 87. Specifically, in the present embodiment, the adjusting knob includes a first adjusting knob 88 and a second adjusting knob 89, the first adjusting knob 88 is used for adjusting the opening and closing degree of the first valve 86 to control the magnitude of the blowing air flow, and the second adjusting knob 89 is used for adjusting the opening and closing degree of the second valve 87 to control the magnitude of the suction air flow.
Of course, in other embodiments, the adjusting knob may be the same knob, so that the opening and closing degree of the first valve 86 and the second valve 87 can be directly adjusted, for example, the adjusting knob is located at the 0 gear under the normal state, at this time, the opening and closing degree of the first valve 86 and the second valve 87 are the same, when the blowing air flow needs to be increased and the suction air flow needs to be decreased, the adjusting knob is located at the-1, -2, -3 gear like one side deflection, and when the blowing air flow needs to be decreased and the suction air flow needs to be increased, the adjusting knob is located at the +1, +2, +3 gear like the other side deflection.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
