[0002] As people's living standards gradually improve, purifiers that can purify the kitchen environment are also widely used in people's homes. Purifiers are mainly used to treat kitchen fume exhaust gas. Electrostatic purifiers are one of the most widely used purifiers. Its advantages are high purification efficiency, which can reach 90%-97%, and good treatment effect on fume. However, due to the high adsorption capacity of the electric field plate, the filter element in the equipment needs to be cleaned regularly, otherwise the purification efficiency will be reduced. Therefore, regular cleaning of the electrostatic purifier is not only conducive to improving the purification efficiency, but also can extend the service life of the product.

[0003] In view of the above situation, there are two main traditional cleaning methods:

[0004] The first is to directly disassemble the cleaning device for cleaning. This method is not only time-consuming and laborious, but also may damage the equipment and cause unnecessary losses if the operator is not familiar with the internal parts of the equipment.

[0005] The second method is to only install a nozzle inside to spray cleaning fluid to achieve the cleaning effect, but the cleaning range of this method cannot cover the entire filter element, and the equipment cannot be cleaned properly. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0026] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0027] See also Figure 2 and Figure 5 The purifier 1 includes a filter element 102, and the cleaning device 101 includes a first driving component 1011, a second driving component 1012, a spray component 1013 and a rotating screw 1014. The spray component 1013 includes a water pipe 10133, a swing shaft 10131 fixed at the bottom of the water pipe 10133, and a plurality of spray heads 10132 fixed at the bottom of the swing shaft 10131. The first driving component 1011 drives the water pipe 10133 and the swing shaft 10131 to rotate and swing, thereby driving the spray head 10132 to swing and spray the cleaning liquid toward the filter element 102;

[0028] Specifically, the second driving component 1012 controls the spray component 1013 to rotate along the axial direction of the rotating screw 1014 by driving the rotating screw 1014 to rotate.

[0029] The present application adopts a design in which the nozzle 10132 rotates and swings with the swing shaft 10131 as a fulcrum and rotates along the axial direction of the rotating screw 1014, so that the cleaning liquid flowing through the swing shaft 10131 and sprayed from the nozzle 10132 arranged at the bottom of the swing shaft 10131 can not only fully cover the filter element 102 without dead angles, but also when the cleaning liquid is sprayed onto the filter element 102, the cleaning liquid will splash back inside the filter element 102, continuously impacting the oil stains, thereby achieving large-scale cleaning of the filter element 102 and improving the cleaning efficiency.

[0030] like Figure 3 and Figure 4 As shown, the first driving component 1011 includes a first driving motor 10111, and a motor shaft 101111 is arranged on the side of the first driving motor 10111 close to the water pipe 10133. A connecting piece 10112 is sleeved on the end of the motor shaft 101111 close to the water pipe 10133. The connecting piece 10112 of the present application plays the role of a coupling, which can transmit torque to the cam shaft 101121, thereby extending the service life of the cleaning device 101.

[0031] Specifically, the connecting member 10112 is provided with a convex shaft 101121, one end of the convex shaft 101121 is connected to the connecting member 10112, and the other end is provided with a slot member 10114 near the water pipe 10133. After assembly, the slot member 10114 is fixedly matched with the water pipe 10133.

[0032] When the present application is working, the motor shaft 101111 will drive the slot part 10114 to rotate together. Since the slot part 10114 is tightly matched with the water pipe 10133, the slot part 10114 makes the water pipe 10133, the swing shaft 10131 connected to the bottom of the water pipe 10133, and the nozzle 10132 fixed at the bottom of the swing shaft 10131 also swing under the drive of the motor shaft 101111.

[0033] like Figure 5 As shown, the water pipe 10133 is provided with a water inlet end 101331, and the water inlet end 101331 is arranged in the horizontal direction and away from the first driving component 1011. The water inlet end 101331 includes a water inlet 113311 and a water outlet 113312. By arranging the water inlet end 101331 in the horizontal direction, the water pipe 10133 can be conveniently connected to the water delivery device, which not only reduces the difficulty of installation and maintenance, but also prevents the equipment from being too large and bloated due to the tilt or vertical arrangement of the water pipe 10133, thereby affecting the aesthetics of the equipment. The water inlet 113311 is connected to a booster pump and a solenoid valve. The booster pump can increase the water pressure when flowing through a low-pressure area, thereby improving the overall water pressure effect. The solenoid valve can open or close the water flow when needed, thereby accurately controlling the amount of water entering the device, which helps to ensure the safe and stable operation of the water inlet end 101331.

[0034] The boost pump and the solenoid valve are conventional means that are easily conceived by those skilled in the art and will not be described in detail here.

[0035] like Figure 6 As shown, the cleaning device 101 includes a first drive fixing component 1015, the first drive fixing component 1015 includes a drive motor fixing part 10151, the second drive component 1012 includes a second drive motor 10121, a screw nut 10152 is arranged on one side of the drive motor fixing part 10151, and a first optical axis sleeve 10153 is arranged on the other side near the second drive motor 10121, the first optical axis sleeve 10153, the drive motor fixing part 10151 and the screw nut 10152 are all connected to the rotating screw 1014, the screw nut 10152 is concentrically matched with the rotating screw 1014, and the first optical axis sleeve 10153 is beneficial to reducing the wear degree of the rotating screw 1014. This friction reduction effect helps to improve the operating efficiency of the present application and extend the service life of the equipment.

[0036] Specifically, the cleaning device 101 also includes a second driving and fixing component 1016, which includes an optical axis 10162 and a fixing plate 10161 arranged on both sides of the cleaning device, and the optical axis 10162 is used to connect the fixing plate 10161, and the optical axis 10162 is parallel to the rotating screw 1014, which can not only further expand the cleaning range, but also improve the overall structural stability of the cleaning device 101, and a second optical axis sleeve 10163 is arranged at the connection position between the optical axis 10162 and the driving motor fixing part 10151, and the optical axis 10162 is concentrically matched with the second optical axis sleeve 10163, and the second optical axis sleeve 10163 has a similar function to the above-mentioned first optical axis sleeve 10153, which will not be elaborated here.

[0037] like Figure 1 As shown, the purifier 1 further includes a drying device 103 , and the drying device 103 is used for drying the filter element 102 .

[0038] Optionally, the drying device 103 may be a hot air dryer. After the filter element 102 is cleaned, the air is heated by a heating system, and the heated air is then transported to the filter element 102 by a ventilation system, thereby reducing the drying time compared to natural drying.

[0039] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
