For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.
[0031] Referring to Figure 1 、 Figure 2 and Figure 3 , the utility model discloses an automatic vacuum adsorption equipment, it includes: electric appliance main body 100, the bottom of electric appliance main body 100 is equipped with the side opening suction cavity 110 of air;Air suction pipe 210, be located in electric appliance main body 100, one end of air suction pipe 210 extends to the inside of suction cavity 110, the other end of air suction pipe 210 is connected with suction pump 220;Door plate 300, it is movably arranged in electric appliance main body 100, door plate 300 is connected with the drive that it opens or closes the side opening of suction cavity 110 and drives;Photoelectric sensor 400, be located in the inner side wall of suction cavity 110, for detecting the foreign matter entering the suction cavity 110;Control module, with photoelectric sensor 400, the drive and suction pump 220 electric connection, for controlling suction pump 220 and drive work or stop.
[0032] When needing to carry out vacuum adsorption work, user inputs instruction to control module to make drive open the side opening of suction cavity 110 with door plate 300, when the foreign matter on the ground enters suction cavity 110, photoelectric sensor 400 senses foreign matter and passes information to control module, thereby controlling suction pump 220 to work to make foreign matter be sucked away by air suction pipe 210, and when stopping vacuum adsorption work, drive makes door plate 300 close the side opening of suction cavity 110, thereby avoiding pet accidentally touching photoelectric sensor 400 and causing suction pump 220 to start, which saves electric energy and helps to prevent pets from being accidentally injured. Wherein, the input instruction mode of user to control module can adopt key switch or through bluetooth, wireless communication and the like start mode.
[0033] Referring to Figure 2In some embodiments of the utility model, the electric appliance body 100 includes base 101 and the shell 102 that is established in base 101, the side wall of base 101 is concave and is formed with the suction cavity 110, the input port of suction pipe 210 is obliquely downwardly arranged to the side opening of suction cavity 110. It can be understood that when the vacuum adsorption work is needed, the control module controls the driver to open the side opening of suction cavity 110 of door plate 300, then the user can push electric appliance body 100 to the place where the foreign matter needs to be adsorbed close to suction cavity 110, or the user uses a broom to sweep the foreign matter into suction cavity 110, at this time, the foreign matter on the ground triggers photoelectric sensor 400, and the control module controls the working start of air suction pump 220, wherein the input port of suction pipe 210 is obliquely downwardly arranged to the direction of the side opening of suction cavity 110, that is, the input port of suction pipe 210 is inclined relative to the ground, and the inclined direction of the input port of suction pipe 210 is towards the side opening of suction cavity 110, so as to facilitate the foreign matter to be quickly sucked in when entering from the side opening of suction cavity 110, and also can ensure that the foreign matter on the ground corresponding to suction cavity 110 can be fully sucked away. In the embodiment, the base 101 is concave and formed with the suction cavity 110 by the way of integral injection molding, which is conducive to reducing the production and processing difficulty.
[0034] Referring to Figure 2 and Figure 4In some embodiments of the utility model, the inner circumferential wall of the air suction cavity 110 includes a circular arc surface 111 perpendicular to the ground and an inclined top surface 112 intersecting with the circular arc surface 111, the inclined top surface 112 is perpendicular to the input port of the air suction pipe 210, and the photoelectric sensor 400 is arranged at a position of the circular arc surface 111 close to the side opening of the air suction cavity 110. It can be understood that the circular arc surface 111, the inclined top surface 112 and the ground can jointly enclose the air suction cavity 110, the input port of the air suction pipe 210 is located on the side of the inclined top surface 112 away from the side opening of the air suction cavity 110, the photoelectric sensor 400 is triggered when the foreign matter enters the air suction cavity 110 to control the starting of the air suction pump 220, and the foreign matter can flow along the circular arc surface 111 and the inclined top surface 112 to the input port of the air suction pipe 210, thereby forming the effect of guiding the foreign matter to converge at the input port of the air suction pipe 210. Moreover, the circular arc surface 111 of the inner circumferential wall of the air suction cavity 110 can prevent fine particles such as dust from hiding. Of course, in other embodiments, the shape of the air suction cavity 110 can also be replaced by other shapes, for example, the air suction cavity 110 is trumpet-shaped, the larger end of the trumpet-shaped air suction cavity 110 constitutes the side opening of the air suction cavity 110, and the same effect of guiding the foreign matter to converge at the input port of the air suction pipe 210 can also be achieved. The photoelectric sensor 400 is arranged at a position of the circular arc surface 111 close to the side opening of the air suction cavity 110, and the photoelectric sensor 400 can be triggered when less foreign matter enters the air suction cavity 110, thereby avoiding the insufficient vacuum adsorption function.
[0035] Referring to Figure 2 and Figure 4 In some embodiments of the utility model, the base 101 is provided with two vertical wall plates 103 connected with two ends of the circular arc surface 111, both ends of the door plate 300 are respectively provided with a rotating shaft part 310 penetrating through the two vertical wall plates 103, the driver is a stepping motor connected with one rotating shaft part 310, and the photoelectric sensor 400 is located in a space enclosed by the door plate 300 and the air suction cavity 110. It can be understood that the two vertical wall plates 103 and the door plate 300 can cooperate to completely close the side opening of the air suction cavity 110, and also provide a reliable mounting position for the rotating connection of the door plate 300 to the base 101. Specifically, when a user inputs an instruction to the control module to open the side opening of the air suction cavity 110, the stepping motor drives the door plate 300 to flip upwards around the rotating shaft part 310 to expose the air suction cavity 110, and when the automatic vacuum adsorption equipment stops working, the stepping motor drives the door plate 300 to flip downwards around the rotating shaft part 310 to close the side opening of the air suction cavity 110. Of course, in other embodiments, the door plate 300 can also adopt a translation mode, and the driver is replaced by a pneumatic cylinder or an electric push rod driving the door plate 300 to reciprocate.
[0036] Referring to Figure 2 andFigure 3 In some embodiments of the present application, the door plate 300 is provided with a plug 320 capable of blocking the input port of the air suction pipe 210, and when the door plate 300 closes the side opening of the air suction cavity 110, the plug 320 blocks the input port of the air suction pipe 210. It can be imagined that when the automatic vacuum suction equipment of the present application stops working for a long time, animals such as cockroaches and mosquitoes may crawl into the inside of the air suction pipe 210 through the input port of the air suction pipe 210, thereby causing pollution. The door plate 300 with the above structure has a plug 320, and when the door plate 300 closes the side opening of the air suction cavity 110, the plug 320 blocks the input port of the air suction pipe 210, thereby avoiding the above problem. Of course, in other embodiments, a one-way valve plate capable of turning towards the inside of the air suction pipe 210 can also be provided at the input port of the air suction pipe 210, but a corresponding sealing structure needs to be configured between the one-way valve plate and the input port of the air suction pipe 210.
[0037] Referring to Figure 3 to Figure 5 In some embodiments of the present application, the air suction port of the air suction pump 220 is connected with a collection barrel 230, and the output port of the air suction pipe 210 communicates with the collection barrel 230. In order to facilitate cleaning of the collection barrel 230, the side of the shell 102 is provided with a drawer cavity 120, the collection barrel 230 is slidingly inserted into the drawer cavity 120, and the air suction port of the air suction pump 220 and the output port of the air suction pipe 210 are both arranged on the bottom wall of the drawer cavity 120. The bottom wall of the collection barrel 230 is provided with a fluid outlet 231 corresponding to the air suction port of the air suction pump 220 and a fluid inlet 232 corresponding to the output port of the air suction pipe 210, and a sealing ring 240 is arranged between the air suction port of the air suction pump 220 and the fluid outlet 231 and between the output port of the air suction pipe 210 and the fluid inlet 232. It should be noted that when the collection barrel 230 is slidingly pulled out of the drawer cavity 120, since the air suction pipe 210 and the air suction pump 220 are fixed relative to the electric appliance main body 100, the air suction port of the air suction pump 220 and the output port of the air suction pipe 210 are both separated from the collection barrel 230. When the collection barrel 230 is slidingly inserted into the drawer cavity 120, the sealing ring 240 between the air suction port of the air suction pump 220 and the fluid outlet 231 and between the output port of the air suction pipe 210 and the fluid inlet 232 can prevent gas leakage and ensure the effectiveness of the vacuum suction function.
[0038] Referring to Figure 3In some embodiments of the utility model, the lower part in the shell 102 is provided with a partition 700, the air suction pipe 210 and the air pump 220 are located below the partition 700, the collection barrel 230 and the drawer cavity 120 are located above the partition 700, the above structure is favorable to the rational division of the internal space of the shell 102, under the premise of ensuring that the vacuum adsorption and air purification functions do not interfere with each other, the utilization rate of the internal space of the shell 102 is further improved, and the compactness of the automatic vacuum adsorption equipment is improved to a greater extent.
[0039] Referring to Figure 4 And Figure 5 In some embodiments of the utility model, the collection barrel 230 includes a box body 233 with an upward opening and a cover plate 234 covering the opening of the box body 233, a feed pipe 235 is fixedly arranged in the box body 233, the lower end of the feed pipe 235 penetrates the bottom wall of the box body 233 to form the fluid inlet 232, the upper end of the feed pipe 235 extends upward to the middle upper part of the box body 233, an air exhaust pipe 236 is fixedly arranged in the box body 233, the lower end of the air exhaust pipe 236 penetrates the bottom wall of the box body 233 to form the fluid outlet 231, and the upper end of the air exhaust pipe 236 is detachably sleeved with a dust filter net pipe 500. It can be understood that when the air pump 220 works, the gas in the collection barrel 230 located outside the dust filter net pipe 500 penetrates the dust filter net pipe 500 into the air exhaust pipe 236, and then is sequentially discharged to the outside of the electric appliance main body 100 through the air pump 220, at this time, the air suction pipe 210 can suck the foreign matters in the air suction cavity 110 into the collection barrel 230, the foreign matters are isolated by the dust filter net pipe 500, a large amount of dust or hair is easy to block the dust filter net pipe 500, the dust filter net pipe 500 is detached from the air exhaust pipe 236 to facilitate replacement or cleaning, and use is convenient. In addition, the upper end of the feed pipe 235 extends upward to the middle upper part of the box body 233, which can avoid the backflow phenomenon of hair, dander or fine particles, thereby ensuring the cleaning effect of the vacuum adsorption work.
[0040] It can be imagined that when the purpose of separating the foreign matters and gas sucked into the collecting barrel 230 is needed to be achieved, in addition to the scheme of adopting the dust filter screen pipe 500, the dust filter screen pipe 500 can also be replaced by a screen cover arranged outside the upper end of the feeding pipe 235, or a net-shaped guardrail is arranged inside the collecting barrel 230, the inside space of the collecting barrel 230 is separated into two independent parts by the net-shaped guardrail, and the feeding pipe 235 and the gas suction pipe 236 are respectively located on the two sides of the net-shaped guardrail. The screen cover is a cloth bag made of non-woven fabric or a cage composed of nylon material, the cloth bag and the cage have small apertures to accommodate dust, hair and other particulate matters, the dust, hair or particulate matters sucked by the air suction pipe 210 will enter the screen cover, and when the screen cover is filled, the screen cover can be detached from the upper end of the feeding pipe 235 to be replaced, or the screen cover is reinstalled on the feeding pipe 235 after the foreign matters are emptied.
[0041] Referring to Figure 4 and Figure 5 In the embodiment, the box body 233 is provided with an L-shaped recess 238 on the side wall away from the drawer cavity 120, and a decorative plate 180 is buckled and connected to the opening of the drawer cavity 120, the L-shaped recess 238 is used for the four fingers of a user's hand to stretch in to pull out the box body 233 outward, forming a pull-free hand design, and after the opening of the drawer cavity 120 is covered by the decorative plate 180, the drawer cavity 120 can not protrude from the surface of the electric appliance main body 100, and when the collecting barrel 230 needs to be pulled out of the drawer cavity 120, the decorative plate 180 can be detached from the opening of the drawer cavity 120.
[0042] Referring to Figure 3 and Figure 4 In some embodiments of the utility model, the dust filter screen pipe 500 comprises a straight cylinder filter screen 510, the two ends of the straight cylinder filter screen 510 are respectively fixedly connected with a connecting sleeve 520 and a mounting end cover 530, the connecting sleeve 520 is detachably inserted into the upper end of the air suction pipe 236, the cover plate 234 is provided with a mounting opening 237 corresponding to the mounting end cover 530, and the mounting end cover 530 is connected with the mounting opening 237 through a rotating buckle structure 540. It can be understood that when the straight cylinder filter screen 510 needs to be replaced or cleaned, the mounting end cover 530 is only needed to be detached from the mounting opening 237, the connecting sleeve 520 is pulled upward to be separated from the air suction pipe 236, and the straight cylinder filter screen 510 and the connecting sleeve 520 can be pulled out of the mounting opening 237, so that the mounting and dismounting of the dust filter screen pipe 500 is very convenient, the rotating buckle structure 540 is used to realize the detachable mounting operation of the mounting end cover 530, which can also avoid that the dust filter screen pipe 500 is easily separated from the air suction pipe 236 when the dust filter screen pipe 500 is vibrated or touched by mistake, and the rotating buckle structure 540 is a common structure of household appliances, which will not be described further.
[0043] Referring to Figure 3In some embodiments of this utility model, the housing 102 is provided with an air duct 130, a filter element 140, and a fan 150 located on the air duct 130. The housing 102 is provided with an air inlet 160 and an air outlet 170 connected to the air duct 130. The air inlet 160 is located above the input port of the suction pipe 210. The automatic vacuum adsorption device with the above structure uses the suction pipe 210 to absorb foreign objects such as dander and hair on the ground. The fan 150 drives the air located above the input port of the suction pipe 210 to be drawn into the air duct 130 inside the housing 102. After being filtered by the filter element 140, it is discharged outward. Thus, it can purify the surrounding air while adsorbing foreign objects on the ground, resulting in good hygiene and cleaning effect. It can also filter hair, particulate matter, etc. floating in the air. Moreover, it integrates the functions of cleaning the ground and purifying the air, has a compact structure, and helps to reduce the cost of using household cleaning tools. Of course, it is conceivable that the control module can independently control the opening and closing of the air pump 220 and the fan 150, thereby achieving single-function use.
[0044] Referring to 4, in some embodiments of this utility model, in order to facilitate the replacement of the filter element 140, the main body of the appliance 100 is provided with a sliding mounting groove 190 with a side opening above the drawer cavity 120. The filter element 140 is slidably disposed in the sliding mounting groove 190 and can enter and exit the sliding mounting groove 190 along the side opening. The middle part of the sliding mounting groove 190 is hollowed out so that airflow can pass through most of the area of the filter element 140. When the filter element 140 is installed in place, the sliding mounting groove 190 only supports the outline edge of the filter element 140. A decorative plate 180 is snapped onto the main body of the appliance 100. The decorative plate 180 can simultaneously close the opening of the drawer cavity 120 and the side opening of the sliding mounting groove 190. When the decorative plate 180 is removed, the collection bucket 230 and the filter element 140 can be pulled out for replacement. Specifically, the interior of the housing 102 has two U-shaped frame strips spaced apart along the height direction, and the sliding mounting groove 110 is located between the two U-shaped frame strips. The middle part of the U-shaped frame strips constitutes the central hollow of the sliding mounting groove 110.
[0045] See Figure 4In some embodiments of the utility model, the air outlet 170 is arranged on the top wall of the shell 102 and opposite to the fan 150, the filter element 140 is below the fan 150, the air inlet 160 is arranged on the opposite two side walls of the shell 102 below the filter element 140, and the air inlet 160 is detachably connected with the primary filter screen 600. It can be understood that the fan 150 drives the gas in the air duct 130 to flow upwards, the external gas enters the air duct 130 from the air inlet 160, then passes through the filter element 140 below, and then is vertically discharged from the air outlet 170, so that the purified gas is discharged from the top of the shell 102 to avoid direct blowing to the human body, and is also beneficial to diffuse into the indoor space. The primary filter screen 600 has larger pores and is mainly used for blocking larger particles and dust to prevent the filter element 140 from being blocked, so as to prolong the service life of the filter element 140. The primary filter screen 600 is detached from the air inlet 160 to facilitate cleaning and avoid reducing the air intake and affecting the air purification efficiency after being used for a period of time. Specifically, the above-mentioned drawer cavity 120 is located between the two air inlets 160, that is, the air inlets 160 are located on the opposite sides of the drawer cavity 120, so that the collection barrel 230 can be taken out without affecting the normal work of the air purification assembly, and the machine does not need to be stopped for operation. Moreover, the drawer cavity 120 occupies a part of the air duct 130, thereby further improving the utilization rate of the internal space of the shell 102 and being beneficial to improving the structural compactness of the automatic vacuum suction equipment to the greatest extent. In the embodiment, the shell 102 is obtained by injection molding, and the drawer cavity 120, the partition plate 700, the sliding installation groove 190 and other corresponding structural features are formed at the same time of injection molding.
