Description

Technical Field

[0001] This application relates to the technical field of mite removal and vacuuming equipment, and in particular to a mite removal and vacuuming device. Background Art

[0002] The mite removal and vacuuming device, also known as a mite remover, can be used to clean dust, as well as bacteria, viruses, mites and other allergens breeding on beds, sofas, carpets and other household items.

[0003] The mite removal and vacuuming device includes a base, a roller brush, a dust collection cup and a negative pressure fan. The dust collection cup, the negative pressure fan and the roller brush are all installed on the base. The negative pressure fan is used to provide suction for the dust collection cup. The roller brush is arranged at the bottom of the base. When the base moves on the household surface, the roller brush can roll relative to the household surface and beat the household surface to expose the hidden dust mites. Then, the dust mites and the like are sucked into the dust collection cup through suction for recycling.

[0004] However, the cleaning effect of the mite removal and vacuuming device in the related art is not good. Summary of the Utility Model

[0005] Based on this, this application provides a mite removal and vacuuming device to solve the problem of poor cleaning effect of the mite removal and vacuuming device in the related art.

[0006] The mite removal and vacuuming device provided by this application includes a housing, a roller brush assembly and a fan assembly. The fan assembly is connected to the housing. The housing has a first roller brush cavity and a second roller brush cavity. The first roller brush cavity and the second roller brush cavity are arranged along the traveling direction of the mite removal and vacuuming device, and the first roller brush cavity is located in front of the housing along the traveling direction of the mite removal and vacuuming device.

[0007] The roller brush assembly includes two roller brushes. One roller brush is arranged in the first roller brush cavity, and the other roller brush is arranged in the second roller brush cavity. The distance between the two roller brushes is less than the rotation diameter of the roller brush. The first roller brush cavity, the second roller brush cavity and the fan assembly are connected in sequence.

[0008] The mite removal and dust suction device provided in the embodiment of the present application is provided with a fan assembly for providing suction force, and two roller brushes are provided, so that one of them is used to pat the surface to be cleaned, thereby causing dust mites hidden deep inside to be fully exposed, and the other roller brush is used to sweep and suck dust mites to collect dust mites. In this way, the cleaning effect of the roller brush assembly can be improved through the coordinated operation of the two roller brushes. A first roller brush chamber and a second roller brush chamber are provided for installing two roller brushes respectively, and the air flow is caused to flow along the first roller brush chamber, the second roller brush chamber and the fan assembly in sequence, so that the dust mites on the surface to be cleaned are fully patted and lifted up by the roller brushes and then uniformly sucked away, thereby improving the cleaning effect of the mite removal and dust suction device. By making the spacing between the two roller brushes smaller than the rotation diameter of the roller brushes, the distance between the first roller brush chamber and the second roller brush chamber is shortened, thereby shortening the distance that the dust mites in the first roller brush chamber move to the second roller brush chamber, and shortening the distance between the first roller brush chamber and the fan assembly, thereby improving the suction force of the first roller brush chamber, thereby improving the cleaning effect of the mite removal and dust suction device. In this way, the cleaning effect of the mite removal and dust suction device provided in the embodiment of the present application is better.

[0009] In a possible implementation, a first air inlet is provided between the first roller brush chamber and the second roller brush chamber, and the first roller brush chamber and the second roller brush chamber are connected through the first air inlet.

[0010] In this way, the first roller brush chamber, the first air inlet, the second roller brush chamber and the fan assembly are connected in sequence, and the airflow flows along the first roller brush chamber, the first air inlet, the second roller brush chamber and the fan assembly in sequence, and finally is discharged out of the shell from the fan assembly. This can better control the flow direction of the airflow, so that the roller brush located in the first roller brush chamber and the roller brush located in the second roller brush chamber perform the operation sequence of front beating and back suction.

[0011] In a possible implementation, the second roller brush chamber is provided with a second air inlet, the second air inlet is located on a side of the second roller brush chamber away from the first roller brush chamber, and the second air inlet is connected to the fan assembly.

[0012] In this way, the first roller brush chamber, the first air inlet, the second roller brush chamber and the second air inlet are arranged in sequence from front to back along the traveling direction of the mite removal and dust suction device, and the first roller brush chamber, the first air inlet, the second roller brush chamber, the second air inlet and the fan assembly are connected in sequence, so that the airflow flows along the first roller brush chamber, the first air inlet, the second roller brush chamber, the second air inlet and the fan assembly in sequence, so that after the roller brush located in the first roller brush chamber hits the surface to be cleaned, the dust mites raised enter the second roller brush chamber through the first air inlet, and then leave the second roller brush chamber through the second air inlet, thereby facilitating the collection of dust mites.

[0013] In a possible implementation, a cross-sectional area of the second air inlet is larger than a cross-sectional area of the first air inlet.

[0014] In this way, the pressure of the first air inlet can be made greater than that of the second air inlet, so as to efficiently suck the lifted dust mites from the first air inlet into the second roller brush cavity, which is conducive to cleaning the dust mites through the roller brush in the second roller brush cavity and finally collecting the dust mites.

[0015] In a possible implementation, the mite removal and dust suction device further includes a dust cup assembly, the dust cup assembly is connected to the housing, and the first roller brush cavity, the second roller brush cavity, the dust cup assembly and the fan assembly are communicated in sequence;

[0016] The fan assembly has a third air inlet, the third air inlet is communicated with the dust cup assembly, and the cross-sectional area of the third air inlet is larger than that of the second air inlet.

[0017] In this way, the cross-sectional areas of the first air inlet, the second air inlet and the third air inlet increase in sequence, and the air flow flows along the first air inlet, the second air inlet and the third air inlet in sequence. Along the flow direction of the air flow, the pressure decreases step by step. The pressure of the first air inlet is relatively large, which can make it more efficient to suck the dust mites from the first air inlet into the second roller brush cavity, and then suck them into the dust cup assembly through the second air inlet.

[0018] In a possible implementation, the rotation directions of the two roller brushes are the same.

[0019] In this way, the two roller brushes can collect the dust mites in one direction, and then be uniformly sucked into the dust cup assembly through the second air inlet.

[0020] In a possible implementation, the two roller brushes both rotate counterclockwise.

[0021] In this way, when the mite removal and dust suction device moves forward on the surface to be cleaned, the two roller brushes can both sweep the dust mites to the rear of the mite removal and dust suction device, which is conducive to collecting the dust mites into the second roller brush cavity, and then being uniformly sucked into the dust cup assembly through the second air inlet.

[0022] In a possible implementation, the two roller brushes include a first roller brush and a second roller brush. The first roller brush is arranged in the first roller brush cavity, the second roller brush is arranged in the second roller brush cavity, and the turning diameters of the first roller brush and the second roller brush are different.

[0023] In this way, when the first roller brush and the second roller brush rotate synchronously, if the turning diameters of the first roller brush and the second roller brush are different, the linear velocities of the first roller brush and the second roller brush are different, which can enhance the beating effect of the first roller brush or the cleaning effect of the second roller brush.

[0024] In a possible implementation, the turning diameter of the first roller brush is larger than that of the second roller brush, and the distance between the first roller brush and the second roller brush is less than the turning diameter of the second roller brush.

[0025] Thus, when the first roller brush and the second roller brush rotate synchronously, the first roller brush has a larger diameter, which can increase the linear speed of the first roller brush, and further improve the beating effect of the first roller brush, thereby improving the cleaning effect of the mite removal and dust suction device. Moreover, the distance between the first roller brush and the second roller brush is small, which can effectively shorten the distance between the first roller brush chamber and the second roller brush chamber, as well as the distance between the first roller brush chamber and the fan assembly.

[0026] In a possible implementation manner, in the height direction of the mite removal and dust suction device, the second air inlet is higher than the rotation axis center of the second roller brush.

[0027] In this way, when the dust mites move to the second air inlet, the inertial force of the dust mites themselves is directed obliquely backward and upward, and the direction of the suction force is also directed obliquely backward and upward. In this way, the directions of the two forces are the same, and then a resultant force is formed, so that the dust mites on the surface to be cleaned can be more efficiently sucked into the dust cup assembly.

[0028] In a possible implementation manner, the first roller brush includes a first cylinder body and a first cleaning member disposed on the outer peripheral surface of the first cylinder body, the second roller brush includes a second cylinder body and a second cleaning member disposed on the outer peripheral surface of the second cylinder body, and the hardness of the second cleaning member is greater than that of the first cleaning member.

[0029] Thus, when the first cylinder body rotates, it can drive the first cleaning member to rotate synchronously, and then the first cleaning member beats the surface to be cleaned to expose the hidden dust mites. When the second cylinder body rotates, it can drive the second cleaning member to rotate synchronously, and then the second cleaning member sweeps the dust mites on the surface to be cleaned. Moreover, the first cleaning member is relatively soft compared to the second cleaning member, which can effectively improve the beating effect of the first roller brush.

[0044] The mite removal vacuum cleaner includes a base, a roller brush, a dust collection cup and a negative pressure fan. The dust collection cup, the negative pressure fan and the roller brush are all installed on the base. The negative pressure fan is used to provide suction for the dust collection cup. The roller brush is arranged at the bottom of the base. When the base moves on the home surface, the roller brush can roll relative to the home surface and beat the home surface to expose the hidden dust mites. Then, the dust mites are sucked into the dust collection cup through suction for recycling. However, the cleaning effect of the mite removal vacuum cleaner in the related art is not good.

[0045] In view of the above problems, the embodiments of the present application provide a mite removal and dust suction device. Two roller brushes are arranged at intervals along the traveling direction of the mite removal and dust suction device. The two roller brushes are respectively arranged in a first roller brush cavity and a second roller brush cavity, so that one of the two roller brushes is located in front of the traveling direction of the mite removal and dust suction device. This roller brush is used to beat the surface to be cleaned, so as to fully expose the hidden dust mites. The other roller brush is located behind the traveling direction of the mite removal and dust suction device. This roller brush is used to clean the dust mites on the surface to be cleaned and assist the fan assembly to suck away the dust mites on the surface to be cleaned. Moreover, the distance between the two roller brushes is less than the turning diameter of the roller brush, so as to reduce the distance between the first roller brush cavity and the second roller brush cavity, so that the dust mites in the first roller brush cavity can be fully sucked into the second roller brush cavity and then recycled together. In this way, the mite removal and dust suction device can realize the function of front beating and rear suction. After fully raising the dust mites on the surface to be cleaned, the dust mites are recycled through greater suction, and the cleaning effect of the mite removal and dust suction device is better.

[0046] The following will describe in detail the specific implementation manners of the mite removal and dust suction device provided in the embodiments of the present application in conjunction with the accompanying drawings.

[0047] Referring Figures 1 to 5 As shown, the mite removal and dust suction device provided in the embodiments of the present application includes a housing 100, a roller brush assembly 200, and a fan assembly 300. The fan assembly 300 is connected to the housing 100. The housing 100 has a first roller brush chamber 110 and a second roller brush chamber 120. The first roller brush chamber 110 and the second roller brush chamber 120 are arranged along the traveling direction of the mite removal and dust suction device, and the first roller brush chamber 110 is located in front of the housing 100 along the traveling direction of the mite removal and dust suction device. Among them, the traveling direction of the dust suction device can be referred to Figure 1 and Figure 4 the X direction in

[0048] The roller brush assembly 200 includes two roller brushes 210. One roller brush 210 is arranged in the first roller brush chamber 110, and the other roller brush 210 is arranged in the second roller brush chamber 120. The distance between the two roller brushes 210 is less than the rotation diameter of the roller brush 210. The first roller brush chamber 110, the second roller brush chamber 120, and the fan assembly 300 are communicated in sequence.

[0049] In the present application, the housing 100 is used to install the roller brush assembly 200, the fan assembly 300, etc., and moves on the surface to be cleaned under the push of an external force. The roller brush assembly 200 is used to roll and contact the surface to be cleaned to beat the surface to be cleaned, so that the dust mites hidden deep inside are fully exposed. Moreover, the roller brush assembly 200 can sweep the dust mites, so that the dust mites are separated from the surface to be cleaned under the suction of the fan assembly 300 and then recovered, thereby realizing the deep cleaning of the surface to be cleaned.

[0050] In order to improve the cleaning effect of the roller brush assembly 200, two roller brushes 210 can be arranged at intervals along the traveling direction of the mite removal and dust suction device. That is, one roller brush 210 is arranged in front of the traveling direction of the mite removal and dust suction device, and the other roller brush 210 is arranged behind the traveling direction of the mite removal and dust suction device. Correspondingly, the housing 100 is provided with a first roller brush chamber 110 and a second roller brush chamber 120. The first roller brush chamber 110 is located in front of the housing 100 along the traveling direction of the mite removal and dust suction device, and the second roller brush chamber 120 is located behind the housing 100 along the traveling direction of the mite removal and dust suction device, so as to respectively arrange the two roller brushes 210 in the first roller brush chamber 110 and the second roller brush chamber 120, and the first roller brush chamber 110, the second roller brush chamber 120, and the fan assembly 300 are communicated in sequence.

[0051] In this way, when the user pushes the mite removal and dust suction device forward on the surface to be cleaned, the roller brush 210 in the first roller brush chamber 110 can first pat the surface to be cleaned to fully expose the dust mites hidden deep inside. After being fully patted by the roller brush 210, the dust mites are lifted up. The dust mites in the first roller brush chamber 110 enter the second roller brush chamber 120 under the suction of the fan assembly 300. Then, the roller brush 210 in the second roller brush chamber 120 is used to clean the dust mites on the surface to be cleaned. Finally, the suction provided by the fan assembly 300 is used to suck away the dust mites. In this way, the air flow flows sequentially along the first roller brush chamber 110, the second roller brush chamber 120 and the fan assembly 300, thereby sucking away the dust mites. Moreover, the two roller brushes 210 perform separate operations with clear division of labor. One roller brush 210 focuses on patting, and the other roller brush 210 focuses on cleaning and suction. Thus, the mite removal and dust suction device realizes the function of front patting and rear suction. After fully lifting the dust mites on the surface to be cleaned, the dust mites are collected by a greater suction, which can effectively improve the cleaning effect of the mite removal and dust suction device on the surface to be cleaned.

[0052] Since the first roller brush chamber 110 needs to be connected to the fan assembly 300 through the second roller brush chamber 120, and the second roller brush chamber 120 is closer to the fan assembly 300 than the first roller brush chamber 110, therefore, in order to increase the suction of the first roller brush chamber 110, the distance between the two roller brushes 210 can be made smaller than the rotation diameter of the roller brush 210, so as to shorten the distance between the first roller brush chamber 110 and the second roller brush chamber 120, and further shorten the distance between the first roller brush chamber 110 and the dust cup assembly, thereby increasing the suction of the first roller brush chamber 110. Moreover, after the distance between the first roller brush chamber 110 and the second roller brush chamber 120 is shortened, the distance that the dust mites move from the first roller brush chamber 110 to the first roller brush chamber 110 can be shortened, which is convenient for more efficiently sucking the lifted dust mites into the second roller brush chamber 120.

[0053] The mite removal and dust suction device provided by the embodiment of the present application includes a housing 100, a roller brush assembly 200, and a fan assembly 300. The housing 100 includes a first roller brush chamber 110 and a second roller brush chamber 120. The roller brush assembly 200 includes a roller brush 210. By providing the fan assembly 300 to provide suction force, and by providing two roller brushes 210, one of which is used to pat the surface to be cleaned, so as to promote the full exposure of dust mites and the like hidden deep inside, and the other roller brush 210 is used to sweep and suck dust mites, so as to facilitate the collection of dust mites. In this way, the cleaning effect of the roller brush assembly 200 can be improved through the collaborative operation of the two roller brushes 210. By providing the first roller brush chamber 110 and the second roller brush chamber 120 to respectively install the two roller brushes 210, and making the air flow sequentially along the first roller brush chamber 110, the second roller brush chamber 120, and the fan assembly 300, so that after the dust mites on the surface to be cleaned are fully patted and lifted by the roller brush 210, they are then uniformly sucked away, thereby improving the cleaning effect of the mite removal and dust suction device. By making the distance between the two roller brushes 210 less than the rotation diameter of the roller brush 210, the distance between the first roller brush chamber 110 and the second roller brush chamber 120 is shortened, and then the distance for the dust mites in the first roller brush chamber 110 to move to the second roller brush chamber 120 is shortened, and the distance between the first roller brush chamber 110 and the fan assembly 300 is shortened, thereby improving the suction force of the first roller brush chamber 110, and thus improving the cleaning effect of the mite removal and dust suction device. In this way, the mite removal and dust suction device provided by the embodiment of the present application has a good cleaning effect.

[0054] Referring to Figures 2 to 5 As shown, in a possible implementation manner, there is a first air inlet 130 between the first roller brush chamber 110 and the second roller brush chamber 120, and the first roller brush chamber 110 and the second roller brush chamber 120 are connected through the first air inlet 130.

[0055] That is to say, the first roller brush chamber 110, the first air inlet 130, the second roller brush chamber 120, and the fan assembly 300 are connected in sequence, and the air flow sequentially flows along the first roller brush chamber 110, the first air inlet 130, the second roller brush chamber 120, and the fan assembly 300, and finally discharges from the fan assembly 300 outside the housing 100. In this way, the flow direction of the air flow can be better controlled, so that the roller brush 210 located in the first roller brush chamber 110 and the roller brush 210 located in the second roller brush chamber 120 execute the operation sequence of patting in the front and sucking in the back.

[0056] It should be noted that the bottoms of the first roller brush chamber 110 and the second roller brush chamber 120 are open. When the bottom surface of the shell 100 is attached to the surface to be cleaned, the bottoms of the first roller brush chamber 110 and the second roller brush chamber 120 are blocked by the surface to be cleaned. When the roller brush 210 located in the first roller brush chamber 110 lifts up the dust mites on the surface to be cleaned, the dust mites in the first roller brush chamber 110 can enter the second roller brush chamber 120 through the first air inlet 130. After the roller brush 210 located in the second roller brush chamber 120 continues to clean the dust mites, the dust mites are sucked away and recycled along with the airflow, and the airflow enters the fan assembly 300 and then is discharged.

[0057] Reference Figure 3 With Figure 5 As shown, in some embodiments, the second roller brush chamber 120 is provided with a second air inlet 140 , which is located on a side of the second roller brush chamber 120 away from the first roller brush chamber 110 , and the second air inlet 140 is connected to the fan assembly 300 .

[0058] In this way, the first roller brush chamber 110, the first air inlet 130, the second roller brush chamber 120 and the second air inlet 140 are arranged in sequence from front to back along the traveling direction of the mite removal and dust suction device, and the first roller brush chamber 110, the first air inlet 130, the second roller brush chamber 120, the second air inlet 140 and the fan assembly 300 are connected in sequence, so that the airflow flows along the first roller brush chamber 110, the first air inlet 130, the second roller brush chamber 120, the second air inlet 140 and the fan assembly 300 in sequence, so that after the roller brush 210 located in the first roller brush chamber 110 taps the surface to be cleaned, the dust mites raised enter the second roller brush chamber 120 through the first air inlet 130, and then leave the second roller brush chamber 120 through the second air inlet 140, thereby facilitating the collection of dust mites.

[0059] In a possible implementation, the cross-sectional area of the second air inlet 140 is greater than the cross-sectional area of the first air inlet 130 .

[0060] It can be understood that the second air inlet 140 is closer to the fan assembly 300, while the first air inlet 130 is farther away from the fan assembly 300. Therefore, in order to increase the pressure at the first air inlet 130, the cross-sectional area of the second air inlet 140 can be made larger than the cross-sectional area of the first air inlet 130. In this way, the pressure of the first air inlet 130 can be greater than the pressure of the second air inlet 140, thereby efficiently sucking the raised dust mites from the first air inlet 130 into the second roller brush chamber 120, which is conducive to cleaning the dust mites through the roller brush 210 in the second roller brush chamber 120 and finally collecting the dust mites.

[0061] Reference Figures 2 to 5As shown, in a possible implementation, the mite and dust suction device further includes a dust cup assembly. The dust cup assembly is connected to the housing 100, and the first brush roller chamber 110, the second brush roller chamber 120, the dust cup assembly, and the fan assembly 300 are communicated in sequence. The fan assembly 300 has a third air inlet 310, and the third air inlet 310 is communicated with the dust cup assembly. The cross-sectional area of the third air inlet 310 is larger than the cross-sectional area of the second air inlet 140.

[0062] In this way, the cross-sectional areas of the first air inlet 130, the second air inlet 140, and the third air inlet 310 increase in sequence, and the air flow flows along the first air inlet 130, the second air inlet 140, and the third air inlet 310 in sequence. Along the flowing direction of the air flow, the pressure decreases step by step. The pressure of the first air inlet 130 is relatively large, which can make it more efficient to suck dust mites from the first air inlet 130 into the second brush roller chamber 120, and then suck them into the dust cup assembly through the second air inlet 140.

[0063] It should be noted that when the axis of the fan assembly 300 is perpendicular to Figure 4 the XY plane in Figure 4 and the mite and dust suction device is cut by the XY plane in

[0064] the cross-sectional areas of the first air inlet 130, the second air inlet 140, and the third air inlet 310 described in the above embodiments can be obtained. Figure 4 Or, when the axis of the fan assembly 300 is consistent with the traveling direction of the mite and dust suction device, and the mite and dust suction device is cut by a plane perpendicular to the axis of the fan assembly 300, the cross-sectional area of the third air inlet 310 described in the above embodiments can be obtained. Then, when the mite and dust suction device is cut by the XY plane in

[0065] In a possible implementation, the rotation directions of the two brush rollers 210 are the same.

[0066] It can be understood that since the air flow flows along the first brush roller chamber 110, the first air inlet 130, the second brush roller chamber 120, the second air inlet 140, the dust cup assembly, and the fan assembly 300 in sequence, the dust mites in the first brush roller chamber 110 need to enter the second brush roller chamber 120 before they can enter the dust cup assembly. When the mite and dust suction device is moving forward, it is necessary to collect dust mites in one direction and finally suck them into the dust cup assembly through the second air inlet 140. Therefore, the rotation directions of the two brush rollers 210 need to be the same so that the two brush rollers 210 can collect dust mites in one direction.

[0067] In some embodiments, both of the two brush rollers 210 rotate counterclockwise.

[0068] That is to say, when the mite removal and dust suction device is working, with the horizontal surface to be cleaned as a reference, both of the two rotary brushes 210 rotate counterclockwise. In this way, when the mite removal and dust suction device moves forward, both of the two rotary brushes 210 can sweep the dust mites to the rear of the mite removal and dust suction device, which is conducive to collecting the dust mites into the second rotary brush chamber 120, and then being uniformly sucked into the dust cup assembly through the second air inlet 140.

[0069] Refer to Figure 3 And Figure 5 As shown, in a possible implementation manner, the two rotary brushes 210 include a first rotary brush 211 and a second rotary brush 212. The first rotary brush 211 is arranged in the first rotary brush chamber 110, and the second rotary brush 212 is arranged in the second rotary brush chamber 120. The rotary diameters of the first rotary brush 211 and the second rotary brush 212 are different.

[0070] That is to say, the first rotary brush 211 is used to pat the surface to be cleaned, so that the dust mites hidden in the surface to be cleaned are fully lifted. The second rotary brush 212 is used to sweep and assist in sucking the dust mites, so that the dust mites are collected into the dust cup assembly. When the first rotary brush 211 and the second rotary brush 212 rotate synchronously, if the rotary diameters of the first rotary brush 211 and the second rotary brush 212 are different, the linear speeds of the first rotary brush 211 and the second rotary brush 212 are different, which can enhance the patting effect of the first rotary brush 211 or enhance the cleaning effect of the second rotary brush 212.

[0071] Among them, the first rotary brush 211 and the second rotary brush 212 can be driven by the same driving motor to make the first rotary brush 211 and the second rotary brush 212 rotate synchronously, thereby simplifying the structure of the mite removal and dust suction device. Or, the first rotary brush 211 and the second rotary brush 212 can also be driven by two driving motors respectively. The embodiments of the present application do not make specific limitations on this.

[0072] In a possible implementation manner, the rotary diameter of the first rotary brush 211 is greater than that of the second rotary brush 212, and the distance between the first rotary brush 211 and the second rotary brush 212 is less than the rotary diameter of the second rotary brush 212.

[0073] In this way, when the first rotary brush 211 and the second rotary brush 212 rotate synchronously, the first rotary brush 211 has a larger diameter, which can increase the linear speed of the first rotary brush 211, thereby improving the patting effect of the first rotary brush 211 and improving the cleaning effect of the mite removal and dust suction device. Moreover, the distance between the first rotary brush 211 and the second rotary brush 212 is small, which can effectively shorten the distance between the first rotary brush chamber 110 and the second rotary brush chamber 120, and shorten the distance between the first rotary brush chamber 110 and the fan assembly 300.

[0074] In some embodiments, when the first rotary brush 211 and the second rotary brush 212 are driven by the same drive motor, considering the load state of the drive motor, the difference between the turning diameter of the first rotary brush 211 and the turning diameter of the second rotary brush 212 can be greater than or equal to 5 mm, thereby improving the beating effect of the first rotary brush 211. For example, the turning diameter of the first rotary brush 211 is 35 mm, and the turning diameter of the second rotary brush 212 is 30 mm.

[0075] In a possible implementation manner, in the height direction of the mite removal and dust suction device, the second air inlet 140 is higher than the axis of rotation of the second rotary brush 212. Wherein, the height direction of the mite removal and dust suction device can refer to Figure 4 the Y direction in

[0076] When the mite removal and dust suction device moves forward, it is necessary to sweep the dust mites to the rear of the mite removal and dust suction device. In this way, the dust mites can be efficiently collected into the second rotary brush chamber 120, and then uniformly sucked into the dust cup assembly through the second air inlet 140. Moreover, the rotation directions of the first rotary brush 211 and the second rotary brush 212 are both counterclockwise. When the dust mites move to the second air inlet 140, the inertial force of the dust mites themselves is directed obliquely rearward and upward, and the direction of the suction force is also directed obliquely rearward and upward. In this way, the directions of the two forces are the same, and thus a resultant force is formed, so that the dust mites on the surface to be cleaned can be more efficiently sucked into the dust cup assembly.

[0077] In a specific implementation, the first rotary brush 211 includes a first cylinder body and a first cleaning member disposed on the outer peripheral surface of the first cylinder body, the second rotary brush 212 includes a second cylinder body and a second cleaning member disposed on the outer peripheral surface of the second cylinder body, and the hardness of the second cleaning member is greater than the hardness of the first cleaning member.

[0078] In this way, when the first cylinder body rotates, it can drive the first cleaning member to rotate synchronously, thereby causing the first cleaning member to beat the surface to be cleaned so as to expose the hidden dust mites. When the second cylinder body rotates, it can drive the second cleaning member to rotate synchronously, thereby causing the second cleaning member to sweep the dust mites on the surface to be cleaned. Moreover, the first cleaning member is relatively soft compared to the second cleaning member, which can effectively improve the beating effect of the first rotary brush 211.

[0079] Exemplarily, the first cleaning member can be made of rubber or soft rubber so that the first cleaning member is relatively soft and heavy, thereby making the beating force of the second cleaning member acting on the surface to be cleaned relatively large, so as to improve the beating effect of the first cleaning member. The second cleaning member can be made of relatively hard bristles, which is beneficial to collecting dust mites and thus improving the cleaning effect of the second cleaning member.

[0080] Wherein, the second cleaning member can protrude from the bottom surface of the housing 100, and the height by which the second cleaning member protrudes from the bottom surface of the housing 100 is greater than or equal to 2 mm. Further, when the bottom surface of the housing 100 is attached to the surface to be cleaned, the second cleaning member has a sufficient interference amount relative to the surface to be cleaned, and the end of the second cleaning member can be partially deformed, thereby improving the cleaning effect of the second rotary brush 212.

[0081] It should be noted that, in the above embodiments, the turning diameter of the second rotary brush 212 described is the radial distance from the end of the second cleaning member to the axis of rotation of the second cylinder.

[0082] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
