DETAILED DESCRIPTION

[0038] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways beyond the specific embodiments described herein and by one of ordinary skill in the art without departing from the spirit and scope of the present application, and it is therefore intended that all such variations be considered as falling within the scope of the present application.

[0039] In the description of the present application, it should be understood that if these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated brush head or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0040] In addition, if these terms "first", "second" appear, these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implying the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, if the term "multiple" appears, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0041] In this application, unless otherwise expressly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like shall be understood broadly. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise expressly limited. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, if there is a description such as "on" or "below" the first feature of the second feature, it means that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0043] It should be noted that if an element is referred to as "fixed to" or "provided on" another element, it can be directly on another element or there can be a middle element. If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element. If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are for illustrative purposes only and are not the only embodiment.

[0044] As in the background art, the acarid removing device is a device specially used to clean dust and allergens such as bacteria and mites breeding on the surface of textiles such as beds, sofas and carpets. When the user uses the acarid removing device for cleaning, it is in contact with the surface to be cleaned. The acarid removing device removes dust and mites on the surface or deep layer of the textile on the bed by beating with a roller brush or a beating block, and then sucks the dust and mites (hereinafter referred to as medium) through a suction port, thereby achieving the purpose of removing mites.

[0045] However, in the existing acarid removing device, for example, when the acarid removing device is placed on the ground, the roller brush generally extends in the horizontal direction at this time. At this time, the suction port of the acarid removing device for dust collection needs to be close to the ground to smoothly suck the dust and mites shaken by the roller brush into the suction port. However, when the suction port needs to be set higher, because the suction port is higher, the dust and mites entering the suction port will not be smooth.

[0046] In order to solve the above problems, refer toFigures 1 to 4 The application provides a dust removal structure 100 for dust removal of a surface to be cleaned. Specifically, the dust removal structure 100 comprises a housing 20 and a brush head assembly 10. The housing 20 has a receiving space 21 and an opening 22 communicating with the receiving space 21. The brush head assembly 10 is arranged in the receiving space 21 and rotationally connected with the housing 20. The brush head assembly 10 can rotate around the axial direction L of the receiving space 21. At least part of the brush head assembly 10 extends out of the receiving space 21 through the opening 22.

[0047] In the embodiment, the brush head assembly 10 has a guide channel 14 extending along the axial direction L of the receiving space 21. The housing 20 further has a dust suction port 23. The dust suction port 23 and the opening 22 are located on both sides of the axial direction L of the receiving space 21. The guide channel 14 is configured to guide the medium on the side of the opening 22 to the dust suction port 23 when the brush head assembly 10 rotates.

[0048] In the actual dust removal process, the part of the brush head assembly 10 extending out of the receiving space 21 through the opening 22 can directly contact the surface to be cleaned. During the rotation of the brush head assembly 10 around the axial direction L of the receiving space 21 in the receiving space 21 relative to the housing 20, the surface to be cleaned is continuously or indirectly hit to form dust medium. The dust medium enters the guide channel 14 through the opening 22 and is guided by the guide channel 14 to the dust suction port 23 away from the surface to be cleaned, thereby completing the dust removal process. In this way, even if the dust suction port 23 is arranged far away from the opening 22 and the surface to be cleaned, such as when the dust suction port 23 is arranged at a high position, efficient dust removal can still be achieved through the guide channel 14.

[0049] Specifically, the guide channel 14 originally exists on the brush head assembly 10. One end of the guide channel 14 extends to one side of the opening 22, and the other end extends to one side of the dust suction port 23. When the dust removal structure 100 needs to remove dust, the brush head assembly 10 is controlled to rotate around the axial direction L of the receiving space 21. At this time, the guide channel 14 actively guides the dust, dirt and other media on the side of the opening 22 to the side of the dust suction port 23, thereby achieving dust removal.

[0050] In a specific embodiment, when the surface to be cleaned is clothes placed on the ground, the opening 22 faces the ground, and the dust suction port 23 is arranged at a high position away from the ground. The guide channel 14 guides the medium near the ground to the high position of the dust suction port 23, thereby achieving dust removal.

[0051] In one embodiment, referring to Figure 1The shell 20 comprises an upper shell 20a and a lower cover 20b. The upper shell 20 forms a receiving space 21. The lower cover 20b covers one end of the upper shell 20a and forms an opening 22 communicating with the receiving space 21. A dust suction port 23 is arranged on the upper shell 20a and located at one end of the receiving space 21 away from the lower cover 20b. Further, a fan can be arranged outside the upper shell 20a to facilitate dust suction through the dust suction port 23.

[0052] In one embodiment, referring to Figure 3 The axial direction L of the receiving space 21 is arranged at an acute angle with a first direction L1 perpendicular to the plane of the opening 22, and the range of the acute angle A is 8-25 degrees.

[0053] For example, when the opening 22 is parallel to the ground, the first direction L1 is the direction of gravity at this time, and the axial direction L intersects the plane of the opening 22. At this time, the brush head assembly 10 is arranged at an angle relative to the ground. When the part of the brush head assembly 10 extending out of the opening 22 abuts against the surface to be cleaned, the brush head assembly 10 is arranged at an angle (not perpendicular) relative to the surface to be cleaned to adjust the abutting area between the part of the brush head assembly 10 extending out of the opening 22 and the surface to be cleaned, so as to avoid the case that the abutting area is too large to cause too much resistance when the brush head assembly 10 strikes the surface to be cleaned, and the case that the abutting area is too small to cause too little contact when the brush head assembly 10 strikes the surface to be cleaned, resulting in poor striking effect.

[0054] In one embodiment, the receiving space 21 comprises two, and each receiving space 21 is provided with a brush head assembly 10, and the dust suction port 23 communicates with the guide channels 14 of the two brush head assemblies 10.

[0055] It can be understood that the more the brush head assemblies 10, the better the cleaning effect on the surface to be cleaned. However, if the brush head assemblies 10 are arranged too much, it will have a great impact on the size and overall structure of the dust removal structure 100. Therefore, in order to ensure the dust removal effect of the dust removal structure 100 on dust and mites on the surface to be cleaned, while ensuring the compact structure of the dust removal structure 100, two brush head assemblies 10 are arranged in the present application.

[0056] Specifically, the brush head assemblies 10 in the two receiving spaces 21 can rotate along different circumferences, one brush head assembly 10 rotates clockwise and one brush head assembly 10 rotates counterclockwise, and the relative rotation of the two brush head assemblies 10 continuously strikes the surface to be cleaned in all directions, thereby improving the dust removal efficiency.

[0057] In one embodiment, referring to Figure 4 and Figure 5The brush head assembly 10 comprises a main body 11, a guiding portion 12 and a dust raising portion 13. The main body 11 is rotatably connected with the shell 20 along the axial direction L of the accommodating space 21. It can be understood that the axial direction L of the accommodating space 21 is the axial direction L of the main body 11. The guiding portion 12 is arranged on the main body 11 and defines a guide channel 14 extending along the axial direction L of the accommodating space 21 together with the main body 11. The dust raising portion 13 is arranged on the side of the main body 11 facing the opening 22 and extends out of the accommodating space 21 through the opening 22.

[0058] The brush head assembly 10 has a working state and a non-working state. When the brush head assembly 10 is in the working state, the brush head assembly 10 rotates in the accommodating space 21 relative to the shell 20 along the axial direction L of the accommodating space 21. When the brush head assembly 10 is in the non-working state, the brush head assembly 10 is stationary in the accommodating space 21.

[0059] Specifically, when the brush head assembly 10 is in the working state, the part of the dust raising portion 13 extending out of the accommodating space 21 through the opening 22 continuously vibrates and hits the surface to be cleaned. At this time, a dust raising area (which can have no clear boundary) with medium is formed between the surface to be cleaned and the brush head assembly 10. The dust raising area is in communication with the guide channel 14 through the opening 22. The guide channel 14 forces the medium in the dust raising area to rotate and flow along the spiral extending guide channel 14 until it reaches the dust suction port 23 at the other end and is sucked away.

[0060] In this way, based on the same concept, the dust raising portion 13 raises dust on the surface to be cleaned to form a dust raising area. The medium in the dust raising area enters the guide channel 14 through the opening 22 and is guided to the dust suction port 23 along the axial direction L of the main body 11. The brush head assembly 10 provides a push to the medium, so that the dust, dust mites and other medium on the surface to be cleaned can be pushed to the dust suction port 23 for dust collection, thereby improving the dust removal efficiency.

[0061] In one embodiment, the main body 11 is conical in shape. On the side in the axial direction L and pointing to the opening 22, the cross section of the main body 11 gradually increases, forming a large size at the bottom (the side close to the opening 22) and a small size at the top (the side close to the dust suction port 23), thereby forming a spiral guide channel 14 to more smoothly guide the medium at one end of the main body 11 to the other end.

[0062] In one embodiment, referring to Figures 1 to 6 The main body 11 comprises a connecting portion 111. The main body 11 is rotatably connected with the shell 20 through the connecting portion 111. The guiding portion 12 comprises a spiral structure 121 protruding from the outer surface of the main body 11. One end of the spiral structure 121 is connected with the connecting portion 111, and the other end extends to the opening 22 along the axial direction L of the accommodating space 21. The spiral structure 121 defines the guide channel 14 together with the main body 11.

[0063] When the main body 11 rotates, the guide channel 14 formed between the helical structure 121 and the main body 11 guides the medium on the opening 22 side to the side close to the connecting part 111. Understandably, at this time, the dust suction port 23 can be arranged on the side close to the connecting part 111, so as to realize the transmission of the medium by the brush head assembly 10 itself.

[0064] In other embodiments, the guide part 12 can also be directly grooved on the outer circumferential surface of the main body 11, which has the same effect as the helical structure 121, which is not limited in the present application.

[0065] In one of the embodiments, the connecting part 111 includes a first connecting end 111a and a second connecting end 111b, and the helical structure 121 includes a first helical column and a second helical column, which are arranged at intervals and connected with the first connecting end 111a and the second connecting end 111b respectively. The first helical column, the second helical column and the main body 11 jointly define the guide channel 14.

[0066] In this way, the brush head assembly 10 of the present application forms a double helical structure 121, which ensures that the distance between the two helical columns is not too far. On the one hand, it ensures the helical guiding effect of the guide channel 14, and on the other hand, it can ensure the pushing efficiency of the medium by the helical structure 121.

[0067] Further, the protrusion height of the first helical column and the protrusion height of the second helical column can be the same, forming two side walls of the guide channel 14, and at this time, the outer circumferential surface of the main body 11 forms the bottom wall of the guide channel 14.

[0068] In one of the embodiments, in the axial direction L, the distance between the connecting part 111 and the plane where the opening 22 is located is greater than the farthest distance between the inner wall of the dust suction port 23 and the plane where the opening 22 is located.

[0069] Understandably, the dust suction port 23 has a certain area, and in the axial direction L, the inner wall of the dust suction port 23 has a part closest to the plane where the opening 22 is located (defined as the nearest end) and a part farthest from the plane where the opening 22 is located (defined as the farthest end), and at this time, the other areas of the dust suction port 23 are all located between the nearest end and the farthest end.

[0070] In the working process of the brush head assembly 10, the medium in the dust raising area can enter the guide channel 14 through the opening 22 and be guided along the helical extension direction of the guide channel 14. If the guide channel 14 guides it to the position of the connecting part 111, the substances such as hair in the medium will directly wind around the connecting part 111, thereby affecting the normal work of the brush head assembly 10.

[0071] Therefore, in order to avoid this situation, the distance between the connecting portion 111 and the plane where the opening 22 is located is greater than the distance between the farthest end of the dust suction port 23 and the plane where the opening 22 is located, so that the dust suction port 23 is closer to the opening 22 than the connecting portion 111, and the medium is sucked through the dust suction port 23 before reaching the connecting portion 111, thereby ensuring that the rotation of the brush head assembly 10 is not affected by the transmission of the medium.

[0072] In one embodiment, the dimension of the main body 11 in the axial direction L is in the range of 40mm-70mm. The pitch of the spiral structure 121 is in the range of 25mm-60mm. Moreover, the distance between the connecting portion 111 and the plane where the opening 22 is located in the axial direction L is greater than the difference between the farthest distance between the inner wall of the dust suction port 23 and the plane where the opening 22 is located and 4mm.

[0073] It can be understood that the axial dimension of the main body 11 basically determines the height of the dust removal structure 100 in the axial direction L, and therefore, in order to ensure that the volume of the dust removal structure 100 is not too large while ensuring the efficient transmission of the guide channel 14, the dimension of the main body 11 in the axial direction L is limited to the range of 40mm-70mm. The pitch of the spiral structure 121 is in the range of 25mm-60mm.

[0074] Further, the distance between the connecting portion 111 and the plane where the opening 22 is located is greater than the difference between the farthest distance between the inner wall of the dust suction port 23 and the plane where the opening 22 is located and 4mm, and less than the pitch of the spiral structure 121, thereby further ensuring the normal operation of the brush head assembly 10 for a long time.

[0075] It is worth noting that the pitch of the spiral structure 121 refers to the distance between adjacent threads of the same spiral structure 121, and when the spiral structure 121 includes a first spiral column and a second spiral column, the pitch of the spiral structure 121 refers to the pitch of the first spiral column and the pitch of the second spiral column, respectively.

[0076] In one embodiment, the dust raising portion 13 includes a beating member 131 and a sweeping member 132, at least a part of the beating member 131 extends out of the receiving space 21 through the opening 22, and the beating member 131 is used to beat the surface to be cleaned. The sweeping member 132 rotates with the main body 11 and forms a dust raising area.

[0077] The part of the beating member 131 extending out of the opening 22 can directly abut against the surface to be cleaned, and with the rotation of the main body 11, the beating member 131 continuously or intermittently beats the surface to be cleaned to beat the medium on the surface to be cleaned off the surface to be cleaned. At the same time, the sweeping member 132 rotates with the main body 11 and forms a rotating airflow, so that the medium separated from the surface to be cleaned rotates and forms a dust raising area, and then enters the guide channel 14 through the opening 22.

[0078] Further, the main body 11 has an action surface at one end of the axial direction L, and the connecting portion 111 is disposed at the other end of the axial direction L of the main body 11, and the beating member 131 is disposed on the action surface to directly abut against the surface to be cleaned when the brush head assembly 10 is in the working state. The cleaning member 132 includes a plurality of brush strips 132a, which are disposed at the outer edge 151 of the action surface in the circumferential direction and are disposed at an obtuse angle with the plane in which the opening 22 is located in the axial direction of each brush strip 132a, forming a cleaning member 132 that expands outward in the circumferential direction, so as to ensure that the medium dust separated from the surface to be cleaned can be carried into the guide channel 14 in a large range.

[0079] Specifically, referring to Figure 7 , a virtual surface is defined, the plane of the virtual surface is perpendicular to the axial direction L of the main body 11, and the brush head assembly 10 is orthogonally projected on the virtual surface. At this time, the action surface and the brush strip 132a extending away from the center of the circle from the outer edge 151 of the action surface can be seen (or the outer edge 151 of the action surface, the connecting portion 111 and the brush strip 132a extending away from the center of the circle from the outer edge 151 of the action surface) and each brush strip 132a has an intersection with the outer edge 151 of the action surface. The axial direction L of the brush strip 132a extends in a direction opposite to the direction of rotation of the main body 11.

[0080] In one embodiment, the beating member 131 includes a plurality of beating strips 131a, which are protrudingly disposed on the side of the main body 11 facing the opening 22, and the plurality of brush strips 132a are circumferentially disposed outside the beating strips 131a.

[0081] When the brush head assembly 10 is in the working state, at least part of the plurality of beating strips 131a contacts and beats the surface to be cleaned, and the brush strip 132a is circumferentially disposed to form a dust lifting area. Each beating strip 131a has a beating surface. Understandably, since the brush head assembly 10 is obliquely disposed, the beating surface is also not disposed in close contact with the surface to be cleaned.

[0082] Further, the specific shape and protrusion height of the beating strip 131a can be set such that the included angle between the beating surface and the surface to be cleaned is set to be 2-8 degrees, so as to ensure that the contact area between the beating strip 131a and the surface to be cleaned is within a suitable range, and the resistance is not too large, while the beating strip 131a can effectively beat.

[0083] In one embodiment, the height of the beating strip 131a in the axial direction L of the main body 11 is 7-12 mm, and the thickness of the beating strip 131a is 1.5-4.5 mm, so as to ensure the beating effect of the beating strip 131a.

[0084] In one of the embodiments, the dust removal structure 100 further comprises a driving assembly 30, which is arranged in the housing 20 and outside the receiving space 21, and is drivingly connected with the connecting portion 111 of the brush head assembly 10 and used to drive the circumferential rotation of the main body 11.
