[0057] In the related art, a mite remover includes a base and a dust cup assembly mounted on the base. The dust cup assembly includes a dust cup and a cyclone cone located inside the dust cup. A cyclone channel is formed between the cyclone cone and the inner wall of the dust cup. Filter holes are provided on the side wall of the cyclone cone. A dust suction port is provided on the base, and an air inlet communicating with the dust suction port is provided on the side wall of the dust cup. When the mite remover operates, dust particles are sucked in from the dust suction port and enter the cyclone channel through the air inlet for dust-gas separation to achieve the purpose of dust suction. However, the dust particles entering the cyclone channel are likely to be adsorbed in the filter holes on the side wall of the cyclone cone in the air duct, resulting in blockage of the filter holes, thereby causing the suction force to decay during dust suction of the mite removal device, affecting the dust suction performance of the mite removal device, and leading to the technical problem of the decline in the dust suction performance of the mite removal device.

[0058] To solve the above problems, the present application provides a dust cup assembly and a mite removal device. By providing a guiding structure in the air duct, the dust-gas entering the air duct from the air inlet is guided to the inner wall of the dust cup, so that the dust-gas entering the air duct moves along the inner wall of the dust cup in the air duct, making the dust-gas away from the side wall of the cyclone cone, thereby preventing the dust particles in the dust-gas from blocking the filter holes on the side wall of the cyclone cone, ensuring that the suction force does not decay during dust suction, and further ensuring the dust suction performance and dust suction effect.

[0059] In order to make the above objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0060] The embodiments of the present application provide a dust cup assembly. The dust cup assembly includes but is not limited to being applied to a mite removal device to achieve the function of dust suction. For example, the dust cup assembly can also be applied to devices such as vacuum cleaners.

[0061] Hereinafter, the case where the dust cup assembly is applied to a mite removal device will be taken as an example for introduction.

[0062] Please refer to Figure 1As shown in the figure, the mite removal device 10 provided in the embodiment of the present application has functions including but not limited to mite removal by beating, sterilization, and dust collection. The mite removal device 10 includes a device body 200 and a dust cup assembly 100 disposed on the device body 200. A dust suction port is provided at the bottom of the device body 200. The dust cup assembly 100 has an air inlet 111, an air duct 130, and an air outlet. The air inlet 111 is communicated with the dust suction port, and the air duct 130 is communicated with the air inlet 111 and the air outlet respectively. In this way, when the mite removal device 10 operates, by moving the mite removal device 10, dust particles can be sucked into the air duct 130 through the dust suction port and the air inlet 111, and after dust-air separation in the air duct 130, the purified air is discharged into the air through the air outlet to achieve the purpose of dust collection.

[0063] Among them, the structure of the device body 200 of the mite removal device 10 can refer to the related art and will not be elaborated here.

[0064] Next, the dust cup assembly 100 provided in the embodiment of the present application will be introduced in detail with reference to the accompanying drawings.

[0065] Please refer to Figure 2 and Figure 3 As shown in the figure, the dust cup assembly 100 provided in the embodiment of the present application includes a dust cup 110 and a cyclone cone 120. The cyclone cone 120 is disposed in the dust cup 110. It can be understood that the dust cup 110 has a receiving cavity, and the cyclone cone 120 is located in the receiving cavity. An air duct 130 is formed between the outer wall of the cyclone cone 120 and the inner wall of the dust cup 110. It can be understood that the air flow carrying dust particles flowing in the air duct 130 can be called dust-air. Under the action of the driving force, the air duct 130 can separate the gas and dust particles in the dust-air. Exemplarily, an annular air duct 130 is formed between the outer wall of the cyclone cone 120 and the inner wall of the dust cup 110, and the air flow runs along the annular air duct 130 in the air duct 130, for example, from bottom to top. In this way, when the dust-air runs, the gas and dust particles are separated by centrifugal force.

[0066] Among them, the side wall of the dust cup 110 has an air inlet 111 communicated with the air duct 130. When the dust cup 110 is disposed on the device body 200 of the mite removal device 10, the air inlet 111 is arranged facing the dust suction port on the device body 200 so that the dust-air sucked by the dust suction port can enter the air duct 130 through the air inlet 111 for dust-air separation.

[0067] In addition, the side wall of the cyclone cone 120 is provided with filter holes 121. The cyclone cone 120 encloses to form a filter chamber. A HEPA 170 is arranged in the filter chamber. The HEPA 170 is fixed on a HEPA frame 180. The HEPA frame 180 can be connected to the cyclone cone 120 to provide a support base for the HEPA 170. A seal 190 is also arranged at the connection between the HEPA 170 and the HEPA frame 180 to improve the sealing performance between the HEPA 170 and the HEPA frame 180. Exemplarily, the seal is a sealing structure such as a sealing ring, a gasket, or a sealing strip made of materials such as rubber or silica gel. In addition, one end of the cyclone cone 120 far from the air inlet 111 also has an air outlet. The dust cup assembly 100 further includes a blower. When the blower operates, it provides an adsorption force flowing from the air inlet 111, the air duct 130 to the air outlet direction, so that the air flow carries dust particles to form dust-laden air, which enters the air duct 130 through the dust suction port and the air inlet 111. Dust-air separation is carried out in the air duct 130. The gas after dust-air separation enters the filter chamber through the filter holes 121 on the side wall of the cyclone cone 120 for rough filtration, and is finely filtered by the HEPA 170 in the filter chamber. The filtered clean gas is discharged through the air outlet, and the separated dust particles are collected in the dust cup 110 to achieve the purpose of dust suction.

[0068] When dust-air separation is carried out in the air duct 130, the dust particles in the air duct 130 are easily adsorbed on the filter holes 121 on the side wall of the cyclone cone 120 under the action of the adsorption force of the blower, resulting in the filter holes 121 being easily blocked. In this way, the dust suction wind force in the air duct 130 will be weakened, resulting in a problem of decreased dust suction ability.

[0069] Based on the above problems, please continue to refer to Figure 2 and Figure 3 As shown, in the embodiment of the present application, a guiding structure 140 is provided at a position corresponding to the air inlet 111 in the air duct 130 to guide the dust-laden air entering the air duct 130 from the air inlet 111 to the inner wall of the dust cup 110 (as shown in Figure 5 ), that is, to guide the dust-laden air in the air duct 130 to a position close to the inner wall of the dust cup 110 and far from the cyclone cone 120. In this way, under the suction force of the blower, the dust-laden air in the air duct 130 moves along the wall surface close to the inner wall of the dust cup 110 in the air duct 130, so that the dust-laden air in the air duct 130 is far from the side wall of the cyclone cone 120, thereby avoiding the problem that the dust particles in the air duct 130 are adsorbed in the filter holes 121 on the side wall of the cyclone cone 120 and causing the filter holes 121 to be blocked.

[0070] It can be understood that, as shown in Figure 2As shown, the air duct 130 is an annular air duct 130 formed between the outer wall surface of the cyclone cone 120 and the inner wall surface of the dust cup 110. When the suction force provided by the fan is, for example, located at the top of the cyclone cone 120, in this way, when the dust-laden air moves in the air duct 130, it performs a spiral motion with the axis of the cyclone cone 120 as the center of rotation (the direction of motion is as shown by the arrows in Figure 4 and Figure 5 . When the dust-laden air in the air duct 130 moves, it will generate a centrifugal force, so that under the action of the centrifugal force, the dust particles and the gas are separated. And through the guiding structure 140, the dust-laden air just entering the air duct 130 from the air inlet 111 is guided to a position close to the inner wall of the dust cup 110, so that the dust particles move along the inner wall surface of the dust cup 110 under the action of the centrifugal force and will not approach the side wall of the cyclone cone 120, thereby avoiding the problem that the dust particles block the filter holes 121.

[0071] It can be seen that in the dust cup assembly 100 provided by the embodiment of the present application, by arranging a guiding structure 140 in the air duct 130 to guide the dust-laden air entering the air duct 130 from the air inlet 111 to the inner wall of the dust cup 110, so that the dust-laden air entering the air duct 130 moves along the inner wall of the dust cup 110 in the air duct 130, making the dust-laden air away from the side wall of the cyclone cone 120, thereby avoiding the dust particles in the dust-laden air from blocking the filter holes 121 on the side wall of the cyclone cone 120, ensuring that the suction force during dust collection does not decay, and further ensuring the dust collection performance and dust collection effect.

[0072] In some embodiments, as shown in Figure 4 , the guiding structure 140 is arranged on the side wall of the cyclone cone 120 facing the air inlet 111. In this way, the cyclone cone 120 can provide a support basis for the guiding structure 140, and there is no need to specially arrange a structure in the air duct 130 to provide a support basis for the guiding structure 140, so as to ensure the stability and guiding reliability of the guiding structure 140.

[0073] In addition, by arranging the guiding structure 140 on the side wall of the cyclone cone 120 corresponding to the air inlet 111, all the dust-laden air entering the air duct 130 from the air inlet 111 can be guided, so as to avoid the problem that the filter holes 121 on the side wall of the cyclone cone 120 are blocked due to incomplete guiding of the dust-laden air, thereby further ensuring the dust collection performance of the dust cup assembly 100 and improving the dust collection effect.

[0074] In some embodiments, the guiding structure 140 and the cyclone cone 120 can be formed into an integral structure by an integral molding process. In this way, the manufacturing process of the dust cup assembly 100 can be reduced, thereby reducing the process cost.

[0075] In order to further improve the guiding property of the dust-laden air entering the air duct 130 from the air inlet 111, in some embodiments, as shown in Figure 4 andFigure 5 As shown, the guiding structure 140 has a guiding portion 141. The guiding portion 141 is arranged facing the air inlet 111. The guiding portion 141 is configured to guide the dust-laden air entering the air duct 130 from the air inlet 111 to the inner wall of the dust cup 110, so as to improve the guiding reliability of the dust-laden air through the guiding portion 141 and avoid dust particles from clogging the filter holes 121 on the side wall of the cyclone cone 120.

[0076] In some embodiments, the guiding portion 141 is at least one of a guiding inclined surface and a guiding arc surface having an included angle with the air inlet direction of the air inlet 111. By setting the guiding portion 141 as at least one of the guiding inclined surface or the guiding arc surface, while guiding the dust-laden air, the structure is simple, easy to implement, and has a low cost.

[0077] In one example, the guiding portion 141 is a guiding inclined surface arranged on the side wall of the cyclone cone 120 and facing the air inlet 111. There is an included angle between the guiding inclined surface and the air inlet direction of the air inlet 111, so as to guide the dust-laden air entering the air inlet 111 to move towards the inner wall of the dust cup 110, so that the dust-laden air moves along the inner wall surface of the dust cup 110 when moving in the air duct 130. The guiding method is simple, easy to process, and has a low process cost.

[0078] Another exemplary, the guiding portion 141 is a guiding arc surface arranged on the side wall of the cyclone cone 120 and facing the air inlet 111. Wherein, the guiding arc surface can be an arc surface, an elliptical arc surface, etc., and there is an included angle between the tangent direction of the guiding arc surface and the air inlet 111. The tangent direction of the guiding arc surface faces the inner wall surface of the dust cup 110, so as to guide the dust-laden air entering the air inlet 111 to move along the inner wall surface of the dust cup 110 and prevent dust particles from clogging the filter holes 121 on the side wall of the cyclone cone 120.

[0079] Exemplarily, as Figure 4 and Figure 5 shown, the guiding portion 141 is a guiding arc surface. In this way, while guiding the dust-laden air, the processing difficulty of the guiding structure 140 is reduced.

[0080] In some embodiments, please continue to refer to Figure 4 and Figure 5As shown, a wind shield 150 is further provided in the dust cup 110. The wind shield 150 is disposed on one side of the air inlet 111 and is connected between the cyclone cone 120 and the inner wall of the dust cup 110. The wind shield 150 is configured to direct the dust-laden air entering from the air inlet 111 to move along a preset direction in the air duct 130. That is to say, by providing the wind shield 150 on one side of the air inlet 111, the dust-laden air entering the air duct 130 from the air inlet 111 moves in one direction along the air duct 130, so as to improve the dust-air separation efficiency and effect, and avoid the problem that the dust-laden air moves to both sides of the air inlet 111 after entering the air duct 130 from the air inlet 111, resulting in poor dust suction effect.

[0081] For example, in Figure 4 and Figure 5 the dust-laden air entering the air duct 130 from the air inlet 111 moves in the direction indicated by the arrow in the figure under the blocking action of the wind shield 150, so as to improve the consistency of the movement direction of the dust-laden air in the air duct 130, and further improve the dust-air separation efficiency and dust suction effect.

[0082] In some embodiments, as shown in Figure 4 and Figure 5 the wind shield 150 is connected to the guiding structure 140, so that the wind shield 150 and the guiding structure 140 jointly guide the dust-laden air entering the air duct 130, so as to improve the separation efficiency and dust suction effect of the dust-laden air in the air duct 130.

[0083] Exemplarily, the wind shield 150, the guiding structure 140 and the cyclone cone 120 may also be an integral structure formed by an integral molding process such as injection molding or casting, so as to reduce the processing process and lower the process cost.

[0084] In some embodiments, please continue to refer to Figure 2 As shown, a wind guiding member 160 is further provided on the side wall of the cyclone cone 120. The wind guiding member 160 spirally extends along the first direction on the outer peripheral side of the cyclone cone 120, so that the air duct 130 is formed into a spiral air duct extending along the first direction; the guiding structure 140 is disposed on the wind guiding member 160 and is connected to the side wall of the cyclone cone 120, wherein the first direction is the axial direction of the cyclone cone 120 (as shown in Figure 4 ).

[0085] In the embodiments of the present application, the air duct 130 is guided to be formed into a spirally extending air duct 130 through the wind guiding member 160, so as to improve the efficiency of the movement of the dust-laden air in the air duct 130, thereby improving the dust-air separation efficiency.

[0086] In some embodiments, such as Figure 2 and Figure 3As shown, the air inlet 111 is provided at a position near the bottom of the dust cup 110, and the guiding structure 140 is provided at a position of the air guiding member 160 near the air inlet 111 and faces the air inlet 111, so as to guide the dust-laden air just entering the air duct 130 to the inner wall of the dust cup 110 through the guiding structure 140, and prevent the filter holes 121 on the side wall of the cyclone cone 120 from being blocked.

[0087] Among them, the contour shape of the air inlet 111 can be a circular hole, an oval hole, a rectangular hole, a trapezoidal hole or any other shape, and no specific limitation is made here.

[0088] In some embodiments, as Figure 4 shown in, the air guiding member 160 includes a first air guiding portion 161, a second air guiding portion 162 and a spiral connecting portion 163. Along the first direction, the first air guiding portion 161 and the second air guiding portion 162 are arranged at intervals and respectively surround the outer peripheral side of the cyclone cone 120. The spiral connecting portion 163 is spiral along the first direction, winds around the outer peripheral side of the cyclone cone 120, and is connected between the first air guiding portion 161 and the second air guiding portion 162. The second air guiding portion 162 is arranged at one end of the cyclone cone 120 close to the air inlet 111, so that through the guiding of the first air guiding portion 161, the second air guiding portion 162 and the spiral connecting portion 163, the dust-laden air moves spirally in the first direction in the air duct 130, so as to improve the effect of separating the dust-laden air in the air duct 130.

[0089] In addition, the guiding structure 140 can be arranged on the second air guiding portion 162 and face the air inlet 111, so as to jointly guide the dust-laden air entering the air duct 130 through the guiding structure 140 and the air guiding member 160, thereby improving the dust-laden air separation effect while preventing dust particles from blocking the filter holes 121 on the side wall of the cyclone cone 120, and thus ensuring the dust suction performance of the dust cup assembly 100.

[0090] In some embodiments, the guiding structure can be integrally formed with the air guiding member 160, the cyclone cone 120, the wind shielding member 150, etc. through an integral molding process such as injection molding and casting, so as to reduce the processing process and lower the process cost.

[0091] Exemplarily, as Figure 4 shown in, the first air guiding portion 161 is a first air guiding plate, the second air guiding portion 162 is a second air guiding plate, the spiral connecting portion 163 is a spiral connecting plate, and the first air guiding plate and the second air guiding plate respectively have an inclined angle with the first direction. In this way, while ensuring the dust-laden air separation effect, the structures of the first air guiding portion 161, the second air guiding portion 162 and the spiral connecting portion 163 are simple, easy to implement, and have low processing costs.

[0092] In some embodiments, please refer to Figure 3 and Figure 6As shown, a partition wall 112 is provided in the dust cup 110. The partition wall 112 divides the dust cup 110 in the second direction to form a dust suction cavity 113 and a dust collection cavity 114, that is, the partition wall 112 divides the accommodation cavity of the dust cup 110 into a dust suction cavity 113 and a dust collection cavity 114. The cyclone cone 120 is disposed in the dust suction cavity 113. At a position near the top of the partition wall 112, there is a dust outlet 1121 communicating with the air duct 130, so that the dust particles after dust-gas separation in the air duct 130 enter the dust collection cavity 114 through the dust outlet 1121; wherein, there is an included angle between the second direction and the axial direction of the cyclone cone 120 (as Figure 6 shown).

[0093] In the embodiment of the present application, by providing a partition wall 112 in the dust cup 110, the dust cup 110 is divided into a dust suction cavity 113 and a dust collection cavity 114 by the partition wall 112. In this way, the dust particles separated in the air duct 130 can be deposited in the dust collection cavity 114 through the dust outlet 1121, which can prevent the separated dust particles from being repeatedly blown up in the dust suction cavity 113 under the action of the wind force in the air duct 130 and blocking the filter holes 121 on the side wall of the cyclone cone 120, thereby ensuring the dust suction performance and effect.

[0094] In some embodiments, the dust outlet 1121 is provided in the moving direction of the dust particles after dust-gas separation in the air duct 130. In this way, it is convenient for the separated dust particles to directly enter the dust collection cavity 114 through the dust outlet 1121, so that the separated dust particles are deposited in the dust collection cavity 114, avoiding the separated dust particles from being repeatedly rolled up under the action of the wind force in the air duct 130, thereby improving the user experience.

[0095] Among them, the dust outlet 1121 can be a notch of any shape such as a rectangle, a circle, an ellipse, a trapezoid, etc. provided at the top of the partition wall 112, as long as it is convenient for the dust particles to enter the integration cavity, and no specific limitation is made here.

[0096] In order to further prevent the dust particles from blocking the filter holes 121 on the side wall of the cyclone cone 120, in the embodiment of the present application, as Figure 3 shown, the dust outlet 1121 and the filter holes 121 are located on different sides of the cyclone cone 120, so that the dust particles are away from the filter holes 121 on the side wall of the cyclone cone 120, preventing the problem of blockage of the filter holes 121, ensuring the suction of the dust cup assembly 100, and ensuring the dust suction performance and effect.

[0097] Exemplarily, while the dust outlet 1121 and the filter holes 121 are located on different sides of the cyclone cone 120, the dust outlet 1121 is also arranged in the tangential direction of the air outlet direction of the spiral air duct, so that the separated dust particles can more easily enter the dust collection cavity 114, preventing the dust particles from blocking the filter holes 121 and improving the efficiency of the dust collection cavity 114 in collecting dust particles.

[0098] In summary, the dust cup assembly provided in the embodiment of the present application includes a dust cup and a cyclone cone. The cyclone cone is arranged in the dust cup, and a air duct is formed between the outer wall of the cyclone cone and the inner wall of the dust cup. An air inlet communicated with the air duct is provided on the side wall of the dust cup; a guiding structure is provided at a position corresponding to the air inlet in the air duct, and the guiding structure is configured to guide the dust-laden air entering from the air inlet to the inner wall of the dust cup, so that the dust-laden air entering the air duct moves along the inner wall of the dust cup in the air duct for dust-air separation. It can be seen that by providing a guiding structure in the air duct to guide the dust-laden air entering the air duct to the inner wall of the dust cup, so that the dust-laden air moves along the inner wall of the dust cup in the air duct, the dust-laden air is kept away from the side wall of the cyclone cone, thus preventing the dust particles in the dust-laden air from blocking the filter holes on the side wall of the cyclone cone, ensuring that the suction force during dust collection does not decay, and further ensuring the dust collection performance and effect.
