Dust removal structure and cleaning device

Abstract

The application relates to a dust removal structure and a cleaning device, which comprises a shell and a brush head assembly. The shell has a receiving space and an opening communicating with the receiving space. The brush head assembly is arranged in the receiving space and rotationally connected with the shell. The brush head assembly can rotate around the axial direction of the receiving space, and at least part of the brush head assembly extends out of the receiving space through the opening and is arranged to intersect the plane of the opening in the axial direction. The brush head assembly has a guide channel extending in the axial direction of the receiving space. The shell also has a dust suction port. The dust suction port and the opening are located at the two ends of the axial direction of the receiving space. The guide channel is configured to guide the medium on the side of the opening to the dust suction port when the brush head assembly rotates. In this way, the brush head assembly pushes the medium, such as dust and dust mites, on the surface to be cleaned to the side of the dust suction port far away from the opening, so that dust suction can be facilitated, and the dust removal efficiency is improved.

Description

Technical Field

[0001] This application relates to the field of household dust removal technology, and in particular to a dust removal structure and cleaning equipment. Background Technology

[0002] A mite remover, also known as a mite vacuum cleaner, is a device used on textiles such as beds, sofas, and carpets to clean small-diameter impurities, as well as bacteria, viruses, mites, and other allergens that breed there.

[0003] Generally, when using a mite-removing vacuum cleaner for cleaning, the dust and dust mites on the surface or deep layers of the bedding are shaken up by the roller brush or the beating block, and then sucked away through the suction port, thereby achieving the purpose of removing mites.

[0004] However, when the suction port of an existing mite-removing vacuum cleaner is set too high, dust and dust mites cannot enter the suction port smoothly, resulting in a reduction in the dust removal effect of the mite-removing vacuum cleaner. Summary of the Invention

[0005] Based on this, this application addresses the problem of poor dust removal and cleaning effects in existing mite removal and dust collection systems by proposing a dust removal structure and cleaning equipment that has a good dust removal and cleaning effect.

[0006] A dust removal structure for removing dust from a surface to be cleaned, comprising:

[0007] The housing has a receiving space and an opening communicating with the receiving space;

[0008] A brush head assembly is disposed within the receiving space and rotatably connected to the housing. The brush head assembly is rotatable about the axial direction of the receiving space, and at least a portion of the brush head assembly extends out of the receiving space through the opening. The axial direction intersects the plane of the opening.

[0009] The brush head assembly has a guide channel extending axially along the receiving space, and the housing also has a suction port. The suction port and the opening are located at both ends of the receiving space along the axial direction. The guide channel is configured to guide the medium on the opening side to the suction port when the brush head assembly rotates.

[0010] In one embodiment, the axial direction of the receiving space is set at an acute angle to a first direction perpendicular to the plane of the opening, and the acute angle is in the range of 8 degrees to 25 degrees.

[0011] In one embodiment, the receiving space includes two, and each receiving space is provided with a brush head assembly;

[0012] Furthermore, the suction port is connected to the guide channels of both brush head assemblies.

[0013] In one embodiment, the brush head assemblies within the two said receiving spaces rotate in different circumferential directions.

[0014] In one embodiment, the brush head assembly includes a body, a guide portion, and a dust-generating portion, wherein the body is rotatably connected to the housing about the axial direction of the receiving space;

[0015] The guide portion is disposed on the main body, and the guide portion and the main body define a guide channel that extends spirally along the axial direction of the receiving space; the dust-generating portion is disposed on the side of the main body facing the opening, and extends at least partially through the opening into the receiving space.

[0016] In one embodiment, the body is cone-shaped, and the cross-section of the body gradually increases in the axial direction and towards the side pointing to the opening.

[0017] In one embodiment, the main body includes a connecting portion, through which the main body is rotatably connected to the housing;

[0018] The guide portion includes a spiral structure that protrudes from the outer peripheral surface of the main body. One end of the spiral structure is connected to the connecting portion, and the other end extends along the axial direction of the receiving space to the opening.

[0019] The spiral structure and the outer peripheral surface of the main body define the guide channel.

[0020] In one embodiment, in the axial direction, the distance between the connecting portion and the plane where the opening is located is greater than the farthest distance between the inner wall of the suction port and the plane where the opening is located.

[0021] In one embodiment, the axial dimension of the main body ranges from 40mm to 70mm, and the pitch of the helical structure is from 12.5mm to 30mm.

[0022] Furthermore, the difference between the distance between the connecting portion and the plane where the opening is located in the axial direction and the farthest distance between the inner wall of the suction port and the plane where the opening is located is greater than 4mm and less than the pitch of the spiral structure.

[0023] In one embodiment, the dust-generating part includes a flapping component and a sweeping component, at least a portion of the flapping component extending out of the receiving space through the opening:

[0024] The tapping component is used to tap the surface to be cleaned, and the sweeping component rotates with the main body to form a dust-raising area. The dust-raising area is connected to the guide channel through the opening.

[0025] In one embodiment, the main body has an action surface located at one end of the axial direction, the tapping member is disposed on the action surface, and the cleaning member includes a plurality of brush strips, which are circumferentially spaced and disposed on the outer edge of the action surface and inclined relative to the action surface.

[0026] The multiple brush strips rotate with the main body and form the dust-generating area.

[0027] In one embodiment, the striking element includes a plurality of striking strips disposed on the working surface;

[0028] Furthermore, the brush strip is arranged around the outer periphery of the tapping strip.

[0029] According to another aspect of this application, a cleaning device is also provided, including the dust removal structure in any of the above embodiments.

[0030] In one embodiment, the cleaning device is a mite remover.

[0031] The aforementioned dust removal structure allows the portion of the brush head assembly extending out of the housing to directly contact the surface to be cleaned, creating a dust-raising area. The media within this area enters the guide channel through the opening and is guided axially to the suction port. The brush head assembly pushes the media, thereby pushing dust, dust mites, and other media from the surface to be cleaned to the side of the suction port, which is farther from the opening, to facilitate suction and improve dust removal efficiency.

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0042] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the brush head or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0047] As described in the background section, a mite remover is a device specifically designed to clean dust and remove bacteria, mites, and other allergens from textiles such as beds, sofas, and carpets. When a user uses a mite remover, it comes into contact with the surface being cleaned. The mite remover uses a roller brush or beating blocks to beat the surface of the bedding or deep layers of the fabric, stirring up dust and dust mites. These are then sucked away through the suction port, thus achieving the purpose of mite removal.

[0048] However, in existing mite removal devices, taking the device placed on the ground as an example, the roller brush generally extends horizontally. In this case, the suction port of the mite removal device needs to be relatively close to the ground to smoothly suck in the dust and dust mites agitated by the roller brush. However, when the suction port needs to be set higher, the dust and dust mites will not be able to enter the suction port smoothly due to the higher position.

[0049] To solve the above problems, see Figures 1 to 4 This application provides a dust removal structure 100 for removing dust from a surface to be cleaned. Specifically, the dust removal structure 100 includes a housing 20 and a brush head assembly 10. The housing 20 assembly has a receiving space 21 and an opening 22 communicating with the receiving space 21. The brush head assembly 10 is disposed within the receiving space 21 and rotatably connected to the housing 20. The brush head assembly 10 is rotatable about the axial direction L of the receiving space 21, and at least a portion of the brush head assembly 10 extends out of the receiving space 21 through the opening 22.

[0050] The brush head assembly 10 has a guide channel 14 extending along the axial direction L of the receiving space 21, and the housing 20 also has a suction port 23. The 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 suction port 23 when the brush head assembly 10 rotates.

[0051] In actual dust removal, the portion of the brush head assembly 10 extending from the opening 22 into the receiving space 21 can directly contact the surface to be cleaned. As the brush head assembly 10 rotates relative to the housing 20 within the receiving space 21 around its axial direction L, it continuously or indirectly taps the surface, creating a dust-generating medium. This medium enters the guide channel 14 through the opening 22, and the guide channel 14 guides the medium from the opening 22 to the suction port 23, which is located away from the surface to be cleaned, thus completing the dust removal process. Therefore, even if the suction port 23 is positioned far from the opening 22 and the surface to be cleaned, such as when the suction port 23 is positioned high, efficient dust removal can still be achieved through the guide channel 14.

[0052] Specifically, the guide channel 14 on the brush head assembly 10 is originally present, with one end extending to one side of the opening 22 and the other end extending to one side of the suction port 23. When the dust removal structure 100 needs to remove dust, the brush head assembly 10 is controlled to rotate circumferentially around the axis 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 suction port 23, thereby achieving dust removal.

[0053] In one specific embodiment, when the surface to be cleaned is clothing or other items placed on the ground, the opening 22 is facing the ground, and the suction port 23 is positioned at a higher position away from the ground. The medium near the ground is guided to the higher suction port 23 position through the guide channel 14 to achieve dust removal.

[0054] In one embodiment, see Figure 1 The housing 20 includes an upper housing 20a and a lower cover 20b. The upper housing 20 forms a receiving space 21. The lower cover 20b covers one end of the upper housing 20a and forms an opening 22 communicating with the receiving space 21. A dust suction port 23 is disposed on the upper housing 20a and located at the end of the receiving space 21 away from the lower cover 20b along the axial direction L. Furthermore, a fan can be provided outside the upper housing 20a to facilitate dust suction through the dust suction port 23.

[0055] In one embodiment, see Figure 3 The axial direction L of the receiving space 21 is set at an acute angle with the first direction L1 perpendicular to the plane where the opening 22 is located, and the acute angle A is in the range of 8 degrees to 25 degrees.

[0056] For example, when the opening 22 is parallel to the ground, the first direction L1 is the direction of gravity, and the axial direction L intersects the plane where the opening 22 is located. At this time, the brush head assembly 10 is tilted relative to the ground. When the part of the brush head assembly 10 extending through the opening 22 abuts against the surface to be cleaned, the brush head assembly 10 is tilted relative to the surface to be cleaned (not perpendicular) to adjust the contact area between the part of the brush head assembly 10 extending through the opening 22 and the surface to be cleaned. This avoids situations where the contact area is too large, resulting in too much resistance when the brush head assembly 10 taps the surface to be cleaned, or too small, resulting in too little contact and poor tapping effect.

[0057] In one embodiment, the receiving space 21 includes two, each receiving space 21 is provided with a brush head assembly 10, and the suction port 23 is connected to the guide channel 14 of the two brush head assemblies 10.

[0058] Understandably, the more brush head assemblies 10 there are, the better the cleaning effect on the surface to be cleaned. However, if too many brush head assemblies 10 are set, it will have a significant 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 the surface to be cleaned, while also ensuring the compact structure of the dust removal structure 100, this application sets two brush head assemblies 10.

[0059] Specifically, the brush head assemblies 10 in the two receiving spaces 21 can rotate in different circumferential directions, so that one brush head assembly 10 rotates clockwise and the other brush head assembly 10 rotates counterclockwise. The two rotate relative to each other to continuously beat the surface to be cleaned in all directions, thereby improving the dust removal efficiency.

[0060] In one embodiment, see Figure 4 and Figure 5 The brush head assembly 10 includes a main body 11, a guide portion 12, and a dust-spraying portion 13. The main body 11 is rotatably connected to the housing 20 about the axial direction L of the receiving space 21. Understandably, the axial direction L of the receiving space 21 is the same as the axial direction L of the main body 11. The guide portion 12 is disposed on the main body 11, and the guide portion 12 and the main body 11 define a guide channel 14 that extends spirally along the axial direction L of the receiving space 21. The dust-spraying portion 13 is disposed on the side of the main body 11 facing the opening 22 and extends at least partially through the opening 22 out of the receiving space 21.

[0061] The brush head assembly 10 is defined to have 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 relative to the housing 20 about the axis L of the housing space 21 within the housing space 21. When the brush head assembly 10 is in the non-working state, the brush head assembly 10 is stationary within the housing space 21.

[0062] Specifically, when the brush head assembly 10 is in operation, as the brush head assembly 10 rotates, the dust-raising part 13, which extends through the opening 22, continuously vibrates and pats the surface to be cleaned. At this time, a dust-raising area with a medium is formed between the surface to be cleaned and the brush head assembly 10 (this area may not have a clear boundary). The dust-raising area is connected to 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 spirally extended guide channel 14 until it reaches the suction port 23 at the other end and is drawn away.

[0063] Thus, based on the same concept, the dust-raising section 13 raises dust on the surface to be cleaned to form a dust-raising area. The media in the dust-raising area enters the guide channel 14 through the opening 22 and is guided to the suction port 23 along the axial direction L of the main body 11. The brush head assembly 10 provides the pushing of the media, thereby pushing the dust, dust mites and other media on the surface to be cleaned to the suction port 23 for vacuuming, thereby improving the dust removal efficiency.

[0064] In one embodiment, the main body 11 is cone-shaped, and the cross-section of the main body 11 gradually increases in the axial direction L and towards the side of the opening 22, forming a large bottom (the side near the opening 22) and a small top (the side near the 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.

[0065] In one embodiment, see Figures 1 to 6 The main body 11 includes a connecting part 111, which is rotatably connected to the housing 20. The guide part 12 includes a spiral structure 121 protruding from the outer surface of the main body 11. One end of the spiral structure 121 is connected to the connecting part 111, and the other end extends along the axial direction L of the receiving space 21 to the opening 22. The spiral structure 121 and the main body 11 define a guide channel 14.

[0066] When the main body 11 rotates, the spiral guide channel 14 formed between the spiral structure 121 and the main body 11 guides the medium on the side of the opening 22 toward the side closer to the connecting part 111. Understandably, at this time, the suction port 23 can be set on the side closer to the connecting part 111, thereby realizing the transmission of the medium by the brush head assembly 10 itself.

[0067] In other embodiments, the guide portion 12 may also be formed by directly cutting a groove on the outer peripheral surface of the main body 11, and its function is the same as that of the spiral structure 121. This application does not limit it here.

[0068] In one embodiment, the connecting portion 111 includes a first connecting end 111a and a second connecting end 111b, and the spiral structure 121 includes a first spiral post 121a and a second spiral post 121b. The first spiral post 121a and the second spiral post 121b are spaced apart and respectively connected to the first connecting end 111a and the second connecting end 111b. The first spiral post 121a, the second spiral post 121b, and the main body 11 together define and form a guide channel 14.

[0069] Thus, the brush head assembly 10 of this application forms a double helix structure 121, ensuring that the distance between the two helical columns is not too far. On the one hand, this ensures the helical guiding effect of the guide channel 14, and on the other hand, it ensures the pushing efficiency of the helical structure 121 for the medium.

[0070] Furthermore, the protrusion height of the first spiral column 121a and the protrusion height of the second spiral column 121b can be the same, forming the two side walls of the guide channel 14. At this time, the outer peripheral surface of the main body 11 forms the bottom wall of the guide channel 14.

[0071] In one embodiment, in the axial direction L, the distance between the connecting portion 111 and the plane where the opening 22 is located is greater than the farthest distance between the inner wall of the suction port 23 and the plane where the opening 22 is located.

[0072] Understandably, the suction port 23 has a certain area. In the axial direction L, the inner wall of the suction port 23 has a part that is closest to the plane where the opening 22 is located (defined as the nearest end) and a part that is farthest from the plane where the opening 22 is located (defined as the farthest end). At this time, all other areas of the suction port 23 are located between the nearest end and the farthest end.

[0073] During the operation of the brush head assembly 10, the medium in the dust-generating area can enter the guide channel 14 through the opening 22 and be guided along the spiral extension direction of the guide channel 14. If the guide channel 14 guides it to the connection part 111, substances such as hair in the medium will directly wrap around the connection part 111, thus affecting the normal operation of the brush head assembly 10.

[0074] Therefore, in order to avoid this situation, the distance between the connecting part 111 and the plane where the opening 22 is located is limited to be greater than the distance between the farthest end of the suction port 23 and the plane where the opening 22 is located, so that the suction port 23 is closer to the opening 22 than the connecting part 111. The medium is sucked away through the suction port 23 before reaching the connecting part 111, thereby ensuring that the rotation of the brush head assembly 10 is not affected by the transmission of the medium.

[0075] In one embodiment, the dimensions of the main body 11 in the axial direction L range from 40mm to 70mm. The pitch of the spiral structure 121 is 25mm to 60mm. Furthermore, the difference between the distance between the connecting portion 111 and the plane containing the opening 22 in the axial direction L and the farthest distance between the inner wall of the suction port 23 and the plane containing the opening 22 is greater than 4mm.

[0076] Understandably, the axial dimension of the main body 11 basically determines the height of the dust removal structure 100 in the axial direction L. Therefore, in order to ensure that the volume of the dust removal structure 100 is not too large while ensuring the effective transmission of the guide channel 14, the dimension of the main body 11 in the axial direction L is limited to 40mm-70mm. The pitch of the spiral structure 121 is 25mm-60mm.

[0077] Furthermore, at this time, the difference between the distance between the connecting part 111 and the plane where the opening 22 is located and the distance between the farthest end of the suction port 23 and the plane where the opening 22 is located is B, 4mm < B < the pitch of the spiral structure 121, thereby further ensuring the normal operation of the brush head assembly 10 for a long time.

[0078] It is worth noting that the pitch of the helical structure 121 refers to the distance between two adjacent threads of the same helical structure 121. When the helical structure 121 includes a first helical post 121a and a second helical post 121b, the pitch of the helical structure 121 refers to the pitch of the first helical post 121a and the pitch of the second helical post 121b, respectively.

[0079] In one embodiment, the dust-generating section 13 includes a striking member 131 and a sweeping member 132. At least a portion of the striking member 131 extends out of the receiving space 21 through the opening 22. The striking member 131 is used to strike the surface to be cleaned, and the sweeping member 132 rotates with the brush head body 11 and forms a dust-generating area.

[0080] The part of the striking component 131 extending out of the opening 22 can directly abut against the surface to be cleaned. As the main body 11 rotates, the striking component 131 continuously or intermittently strikes the surface to be cleaned, knocking the medium on the surface to be cleaned off the surface. At the same time, the sweeping component 132 rotates with the main body 11 and forms a rotating airflow, causing the medium that has detached from the surface to be cleaned to rotate and form a dust area, which then enters the guide channel 14 through the opening 22.

[0081] Furthermore, the main body 11 has an action surface 15 located at one end of the axial direction L. The action surface 15 and the connecting part 111 are respectively disposed at both ends of the main body 11 in the axial direction L. The striking member 131 is disposed on the action surface 15 so as 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. The plurality of brush strips 132a are circumferentially spaced on the outer edge 151 of the action surface 15 and are arranged at an obtuse angle to the plane where the opening 22 is located along the axial direction L of each brush strip 132a, forming a circumferentially outward expanding cleaning member 132 to ensure that the media dust detached from the surface to be cleaned can be agitated and conveyed to the guide channel 14 over a large area.

[0082] Specifically, see Figure 7 A virtual surface is defined, and the plane containing the virtual surface is perpendicular to the axis L of the main body 11. The brush head assembly 10 is projected onto this virtual surface, revealing the working surface 15 and brush strips 132a extending from the outer edge 151 of the working surface 15 away from the center (or the outer edge 151 of the working surface 15, the connecting portion 111, and the brush strips 132a extending from the outer edge 151 of the working surface 15 away from the center). Each brush strip 132a intersects the outer edge 151 of the working surface 15. The axial extension direction L of the brush strip 132a forms an inclination angle G with the diametrical direction passing through this intersection point, with the inclination angle ranging from 10 degrees to 30 degrees. Furthermore, the inclination direction of the brush strip 132a can be set opposite to the rotation direction of the main body 11.

[0083] In one embodiment, the tapping member 131 includes a plurality of tapping strips 131a, the plurality of tapping strips 131a protruding from the side of the main body 11 facing the opening 22, and a plurality of brush strips 132a surrounding the outer periphery of the tapping strips 131a.

[0084] When the brush head assembly 10 is in operation, at least a portion of the plurality of tapping strips 131a contact and tap the surface to be cleaned, and the brush strips 132a surround the periphery to form a dust-generating area. Each tapping strip 131a has a tapping surface, and it is understood that, due to the inclined arrangement of the brush head assembly 10, the tapping surface is not in close contact with the surface to be cleaned.

[0085] Furthermore, by setting the specific shape and protrusion height of the tapping strip 131a, the angle between the tapping surface and the surface to be cleaned can be set to 2-8 degrees, so as to ensure that the contact area between the tapping strip 131a and the surface to be cleaned is within a suitable range, and that effective tapping can be achieved without excessive resistance.

[0086] In one embodiment, the height of the tapping strip 131a ranges from 7mm to 12mm, and the thickness of the tapping strip 131a ranges from 1.5mm to 4.5mm, in order to ensure the tapping effect of the tapping strip 131a.
