As background art, mite-removing instruments are devices specially used for cleaning dust on textiles such as beds, sofas, carpets and the like and allergy sources such as bacteria, mites and the like which are bred. When a user uses the mite removing instrument to clean, the mite removing instrument is contacted with a cleaned surface, and the mite removing instrument beats or beats through the rolling brush or the beating block to flap dust, dust mites and the like on the surface of a fabric on a bed or in a deep layer of the fabric, and then the dust and the dust mites (hereinafter, referred to as medium) are sucked away through the dust suction opening, so that the purpose of removing mites is achieved.

However, in the conventional mite removing device, for example, the mite removing device is placed on the ground, at this time, the rolling brush generally extends along the horizontal direction, and at this time, the dust collection opening of the mite removing device for dust collection needs to be close to the ground to smoothly suck dust, dust mites and the like generated by the rolling brush. However, when the dust suction port needs to be set high, dust mites, and the like are not smoothly introduced into the dust suction port due to the high dust suction port.

In order to solve the above-mentioned problems, referring to fig. 1 to 4, the present application provides a dust removing structure 100 for removing dust from a surface to be cleaned. Specifically, the dust removing structure 100 includes a housing 20 and a brush head assembly 10, the housing 20 has an accommodating space 21 and an opening 22 communicating with the accommodating space 21, the brush head assembly 10 is disposed in the accommodating space 21 and rotatably connected with the housing 20, the brush head assembly 10 can rotate around an axial direction L of the accommodating space 21, and at least a portion of the brush head assembly 10 extends out of the accommodating space 21 through the opening 22.

The brush head assembly 10 has a guide channel 14 extending along an axial direction L of the accommodating space 21, the housing 20 further has a dust collection opening 23, the dust collection opening 23 and the opening 22 are located at two sides of the accommodating space 21 along the axial direction L, and the guide channel 14 is configured to guide a medium at the side of the opening 22 to the dust collection opening 23 when the brush head assembly 10 rotates.

In the actual dust removal process, the part of the brush head assembly 10 extending out of the accommodating space 21 from the opening 22 can be directly contacted with the surface to be cleaned, and in the process that the brush head assembly 10 rotates around the axial direction L of the accommodating space 21 in the accommodating space 21 relative to the shell 20, the surface to be cleaned is continuously or indirectly flapped to form dust-raising media, the dust-raising media enter the guide channel 14 through the opening 22, and the media on the side of the opening 22 are strongly guided to the dust collection opening 23 far away from the surface to be cleaned through the guide effect of the guide channel 14, so that the dust collection process is completed. In this way, even if the dust collection opening 23 is provided at a position farther from the opening 22 and the surface to be cleaned, such as when the dust collection opening 23 is positioned higher, efficient dust collection and removal can be achieved through the guide passage 14.

Specifically, the guiding channel 14 on the brush head assembly 10 is originally present, one end of the guiding channel extends to one side of the opening 22, the other end extends to one side of the dust collection opening 23, when the dust collection structure 100 needs to collect dust, the brush head assembly 10 is controlled to rotate circumferentially around the axial direction L of the accommodating space 21, and at this time, the guiding channel 14 actively guides the medium such as dust and dirt on the side of the opening 22 to one side of the dust collection opening 23, so as to achieve dust collection.

In a specific embodiment, when the surface to be cleaned is clothes placed on the ground, and the opening 22 faces the ground, the dust collection opening 23 is arranged at a higher position away from the ground, and the medium near the ground is guided to the higher position of the dust collection opening 23 through the guide channel 14, so that dust collection and dust removal are realized.

In one embodiment, referring to fig. 1, the housing 20 includes an upper housing 20a and a lower cover 20b, the upper housing 20 forms a housing space 21, the lower cover 20b covers one end of the upper housing 20a and forms an opening 22 communicating with the housing space 21, and the dust collection opening 23 is disposed on the upper housing 20a and is located at one end far from the lower cover 20b in an axial direction L of the housing space 21. Further, a fan may be provided outside the upper case 20a to facilitate dust collection through the dust collection port 23.

In one embodiment, referring to fig. 3, the axial direction L of the accommodating space 21 and the first direction L1 perpendicular to the plane of the opening 22 form an acute angle, and the acute angle a ranges from 8 degrees to 25 degrees.

For example, when the opening 22 is parallel to the ground, the first direction L1 is the gravity direction, and the axial direction L intersects the plane of the opening 22, so that the brush head assembly 10 is disposed obliquely with respect to the ground. When the brush head assembly 10 is abutted against the surface to be cleaned through the portion extending out of the opening 22, the brush head assembly 10 is obliquely arranged (non-perpendicular) relative to the surface to be cleaned, so that the abutting area between the portion extending out of the brush head assembly 10 through the opening 22 and the surface to be cleaned is adjusted, the situation that the resistance is too large when the brush head assembly 10 flaps the surface to be cleaned and the contact is too small when the brush head assembly 10 flaps the surface to be cleaned due to too large abutting area is avoided, and the flapping effect is poor is avoided.

In one embodiment, the accommodating spaces 21 include two brush head assemblies 10, and each accommodating space 21 is provided with a dust collection opening 23 communicated with the guide channels 14 of the two brush head assemblies 10.

It will be appreciated that the more the brush head assembly 10 is, the better the cleaning effect of the surface to be cleaned is, however, if the brush head assembly 10 is too much, the larger the size and the overall structure of the dust removing structure 100 will be affected, so that the dust removing structure 100 can ensure the dust removing effect of dust and mites on the surface to be cleaned, and the dust removing structure 100 is compact in structure.

Specifically, the brush head assemblies 10 in the two accommodating spaces 21 can rotate along different circumferential directions, so that one brush head assembly 10 rotates clockwise, and one brush head assembly 10 rotates anticlockwise, and the two brush head assemblies rotate relatively to continuously flap the surface to be cleaned in all directions, and the dust removal efficiency is improved.

In one embodiment, referring to fig. 4 and 5, the brush head assembly 10 includes a main body 11, a guiding portion 12 and a dust raising portion 13, the main body 11 is rotatably connected with the housing 20 around an axial direction L of the accommodating space 21, it is 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 disposed on the main body 11, the guiding portion 12 and the main body 11 define a guiding channel 14 extending along the axial direction L of the accommodating space 21 in a spiral manner, and the dust raising portion 13 is disposed on a side of the main body 11 facing the opening 22 and extends out of the accommodating space 21 at least partially through the opening 22.

Definition the brush head assembly 10 has an operative state and an inoperative state, the brush head assembly 10 rotates within the housing space 21 about the axial direction L of the housing space 21 relative to the housing 20 when the brush head assembly 10 is in the operative state, and the brush head assembly 10 is stationary within the housing space 21 when the brush head assembly 10 is in the inoperative state.

Specifically, when the brush head assembly 10 is in the working state, along with the rotation of the brush head assembly 10, the part of the dust raising portion 13 extending out through the opening 22 continuously oscillates to flap the surface to be cleaned, at this time, a dust raising area with medium (the area may be free of clear boundary) is formed between the surface to be cleaned and the brush head assembly 10, the dust raising area is communicated with the guide channel 14 through the opening 22, and the guide channel 14 forces the medium in the dust raising area to rotationally flow along the spiral extending guide channel 14 until reaching the dust collection opening 23 at the other end to be pumped away.

Thus, based on the same concept, the dust raising part 13 is used for raising 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 collection opening 23 along the axial direction L of the main body 11, and the brush head assembly 10 is used for pushing the medium, so that the dust, dust mites and other mediums on the surface to be cleaned can be pushed to the dust collection opening 23 for dust collection, and the dust collection efficiency is improved.

In one embodiment, the main body 11 is tapered, and in the axial direction L and directed to one side of the opening 22, the cross section of the main body 11 is gradually increased, the size of the bottom (the side near the opening 22) is formed to be large, and the size of the upper (the side near the dust suction opening 23) is formed to be small, so that the spiral guide passage 14 is formed to guide the medium at one end of the main body 11 to the other end more smoothly.

In one embodiment, referring to fig. 1 to 6, the main body 11 includes a connection part 111, the main body 11 is rotatably connected with the housing 20 through the connection part 111, the guide part 12 includes a spiral structure 121 protruding from an outer surface of the main body 11, one end of the spiral structure 121 is connected with the connection part 111, and the other end extends to the opening 22 along an axial direction L of the receiving space 21; the spiral structure 121 defines a guide channel 14 with the body 11.

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 to the side close to the connecting portion 111, and it can be appreciated that the dust suction opening 23 may be disposed on the side close to the connecting portion 111, so as to implement the transmission of the medium by the brush head assembly 10 itself.

In other embodiments, the guide portion 12 may be directly formed by grooving the outer peripheral surface of the main body 11, and the function thereof is the same as that of the spiral structure 121, which is not limited herein.

In one embodiment, the connection portion 111 includes a first connection end 111a and a second connection end 111b, and the spiral structure 121 includes a first spiral pillar 121a and a second spiral pillar 121b, where the first spiral pillar 121a and the second spiral pillar 121b are spaced apart and connected to the first connection end 111a and the second connection end 111b, respectively. The first helical post 121a, the second helical post 121b and the body 11 together define a guide channel 14.

Thus, the brush head assembly 10 of the present application forms a double helix 121 that ensures that the distance between the two helical studs is not too great. On the one hand, the spiral guiding effect of the guiding channel 14 is ensured, and on the other hand, the pushing efficiency of the spiral structure 121 on the medium can be ensured.

Further, the protrusion height of the first screw column 121a and the protrusion height of the second screw column 121b may be the same, forming both side walls of the guide channel 14, while the outer circumferential surface of the body 11 forms the bottom wall of the guide channel 14.

In one embodiment, in the axial direction L, the distance between the connecting portion 111 and the plane of the opening 22 is greater than the furthest distance between the inner wall of the dust collection opening 23 and the plane of the opening 22.

It will be appreciated that the suction opening 23 has an area, and in the axial direction L, the inner wall of the suction opening 23 has a portion closest to the plane in which the opening 22 is located (defined as the proximal end) and a portion farthest from the plane in which the opening 22 is located (defined as the distal end), and that the other areas of the suction opening 23 are all located between the proximal end and the distal end.

During operation of the brush head assembly 10, the medium in the dust-raising region can enter the guide channel 14 through the opening 22 and is guided along the spiral extending direction of the guide channel 14, and if the guide channel 14 guides the medium to the position of the connecting portion 111, the substance such as hair in the medium can be directly wound on the connecting portion 111, thereby affecting normal operation of the brush head assembly 10.

Therefore, to avoid this, the distance between the connection portion 111 and the plane of the opening 22 is defined to be greater than the distance between the most distal end of the suction opening 23 and the plane of the opening 22, so that the suction opening 23 is closer to the opening 22 than the connection portion 111, and the medium is sucked through the suction opening 23 before reaching the connection portion 111, thereby ensuring that the rotation of the brush head assembly 10 is not affected by the transfer of the medium.

In one embodiment, the body 11 has a dimension in the axial direction L in the range of 40mm-70mm. The pitch of the helical structure 121 is 25mm-60mm. And, the difference between the distance between the connecting portion 111 and the plane of the opening 22 in the axial direction L and the farthest distance between the inner wall of the dust collection opening 23 and the plane of the opening 22 is greater than 4mm.

It will be appreciated that the axial dimension of the body 11 substantially determines the height of the dust extraction structure 100 in the axial direction L, and therefore, in order to ensure that the volume of the dust extraction structure 100 is not excessive while ensuring efficient transport of the guide channel 14, the body 11 is limited to a dimension in the range 40mm-70mm in the axial direction L. The pitch of the helical structure 121 is 25mm-60mm.

Further, at this time, the difference between the distance between the connecting portion 111 and the plane of the opening 22 and the distance between the most distal end of the dust collection opening 23 and the plane of the opening 22 is B, and the pitch of the spiral structure 121 is 4mm < B, so that the long-term normal operation of the brush head assembly 10 is further ensured.

It is noted that the pitch of the spiral structure 121 refers to the distance between two adjacent threads of the same spiral structure 121, and when the spiral structure 121 includes a first spiral pillar 121a and a second spiral pillar 121b, the pitch of the spiral structure 121 refers to the pitch of the first spiral pillar 121a and the pitch of the second spiral pillar 121b, respectively.

In one embodiment, the dust-raising portion 13 includes a beating member 131 and a cleaning member 132, at least a portion of the beating member 131 extends out of the accommodating space 21 through the opening 22, the beating member 131 is used for beating a surface to be cleaned, and the cleaning member 132 rotates along with the brush head body 11 and forms a dust-raising area.

The part of the beating member 131 extending out of the opening 22 can be directly abutted against the surface to be cleaned, and as the main body 11 rotates, the beating member 131 continuously or intermittently beats the surface to be cleaned to beat the medium on the surface to be cleaned until the medium is separated from the surface to be cleaned, and meanwhile, the cleaning member 132 rotates along with the main body 11 and forms a rotating air flow, so that the medium separated from the surface to be cleaned rotates along with the rotating air flow to form a dust raising area, and then enters the guide channel 14 through the opening 22.

Further, the main body 11 has an acting surface 15 at one end in the axial direction L, the acting surface 15 and the connecting portion 111 are disposed at two ends in the axial direction L of the main body 11, and the beating member 131 is disposed on the acting surface 15 to directly contact with 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, and the plurality of brush strips 132a are circumferentially disposed at intervals on the outer edge 151 of the acting surface 15 and form an obtuse angle with the plane of the opening 22 along the axial extending direction of each brush strip 132a, so as to form the cleaning member 132 that expands circumferentially and outwardly, so as to ensure that the medium separated from the surface to be cleaned can raise dust and be conveyed into the guide channel 14 in a large range.

Specifically, referring to fig. 7, a dummy surface is defined, the plane of the dummy surface is perpendicular to the axial direction L of the main body 11, and the brush head assembly 10 is projected on the dummy surface, so that the active surface 15 and the brush bar 132a extending from the outer edge 151 of the active surface 15 in a direction away from the center of the circle can be seen, (or the outer edge 151 of the active surface 15, the connecting portion 111 and the brush bar 132a extending from the outer edge 151 of the active surface 15 in a direction away from the center of the circle) are seen, each brush bar 132a has an intersection point with the outer edge 151 of the active surface 15, and an inclination angle G is formed between the axial direction L of the brush bar 132a and a diameter direction passing through the intersection point, and the inclination angle ranges from 10 degrees to 30 degrees. Further, the inclination direction of the brush bar 132a may be opposite to the rotation direction of the main body 11.

In one embodiment, the beating member 131 includes a plurality of beating bars 131a, the plurality of beating bars 131a are protruded at a side of the main body 11 facing the opening 22, and the plurality of brush bars 132a are circumferentially provided around the beating bars 131 a.

When the brush head assembly 10 is in an operating state, at least part of the plurality of beating strips 131a is contacted with the surface to be cleaned and beats, and the periphery of the brush strips 132a forms a dust raising area. Each of the beater bars 131a has a beater face, and it will be appreciated that the beater faces are not in close proximity to the cleaning to be performed due to the inclined arrangement of the brush head assembly 10.

Further, the specific shape and the protrusion height of the flapping strip 131a can be set, so that the included angle between the flapping surface and the surface to be cleaned is set according to 2-8 degrees, the contact area between the flapping strip 131a and the surface to be cleaned is ensured to be in a proper range, and effective flapping can be realized while the resistance is not too large.

In one embodiment, the height of the tapping rod 131a in the axial direction L of the main body 11 ranges from 7mm to 12mm, and the thickness of the tapping rod 131a ranges from 1.5mm to 4.5mm, so as to ensure the tapping effect of the tapping rod 131 a.
