Description

Technical Field

[0001] The utility model relates to the field of cleaning tools, in particular to an anti-entanglement hair rolling brush mechanism and a cleaning device. Background Art

[0002] As people's living standards continue to improve, their requirements for living environment are getting higher and higher. Cleaning tools are being used more and more widely, and have a very broad market prospect. Sweeping robots, also known as sweeping machines, automatic sweeping machines, smart vacuum cleaners, etc., are a type of cleaning tool that can automatically clean the floor in the room with a certain degree of artificial intelligence. At present, some sweeping robots have dust collection functions to reduce the frequency of users cleaning garbage in the sweeping robots.

[0003] At present, most of the roller brushes of sweeping machines are single-bristle roller brushes, rubber-bristle integrated roller brushes and pure rubber stick roller brushes. The existing roller brushes on the market have different degrees of hair entanglement problems; or the roller brush is implanted with a powered blade structure. Although it solves the hair entanglement problem to a certain extent, it is relatively complex in structure and has a high cost. Utility Model Content

[0004] In order to overcome the deficiencies in the prior art, the utility model provides an anti-entanglement roller brush mechanism, which has a main knife structure arranged on the cleaning roller brush and an auxiliary knife structure arranged in a roller brush mounting groove. When the cleaning roller brush rotates, the hair wound around the cleaning roller brush is supported by the main knife structure and rubs against the auxiliary knife structure when passing through the auxiliary knife structure, thereby cutting off the hair and realizing the anti-entanglement function. The structure is simple, the operation is reliable, the actual production is convenient, and the cost is low. The utility model also provides a cleaning device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hair-tangle-proof roller brush mechanism comprises a mounting base and a cleaning roller brush structure, wherein the mounting base is provided with a roller brush mounting groove matching the cleaning roller brush structure, and the cleaning roller brush structure is installed in the roller brush mounting groove; the cleaning roller brush structure comprises a cleaning roller brush rotatable around its axis, and the cleaning roller brush is provided with a main knife structure, and the main knife structure is extended along the axial direction of the cleaning roller brush; the roller brush mounting groove is provided with an auxiliary knife structure opposite to the cleaning roller brush, and the auxiliary knife structure is extended along the axial direction of the cleaning roller brush; when the cleaning roller brush rotates so that the main knife structure passes through the auxiliary knife structure, the side of the main knife structure facing the auxiliary knife structure is in contact with or has a clearance fit with the side of the auxiliary knife structure facing the main knife structure.

[0007] With the above structure, when the cleaning roller rotates to perform cleaning work, the main blade structure will rotate synchronously with the cleaning roller brush, so that the main blade structure passes through the auxiliary blade structure again and again; due to the contact fit or clearance fit between the main blade structure and the auxiliary blade structure, the hair wrapped around the cleaning roller brush is supported by the main blade structure and rubs against the auxiliary blade structure when passing through the auxiliary blade structure, thereby cutting off the hair and realizing the anti-winding function; the above structure can simplify the structure, making the structure simple and reliable in operation, convenient for actual production, and low in cost.

[0008] Furthermore, the cleaning roller brush rotates so that when the main knife structure passes through the auxiliary knife structure, a side of the main knife structure facing the auxiliary knife structure contacts and cooperates with a side of the auxiliary knife structure facing the main knife structure;

[0009] The auxiliary knife structure is rotatably arranged in the roller brush installation groove, and the rotation axis of the auxiliary knife structure is located on a side of the auxiliary knife structure away from the cleaning roller brush and is parallel to the axis of the cleaning roller brush.

[0010] With the above structure, the contact and cooperation between the main blade structure and the auxiliary blade structure makes the cooperation between the main blade structure and the auxiliary blade structure more reasonable, which is convenient for friction cutting of hair; the clearance cooperation between the main blade structure and the auxiliary blade structure realizes friction cutting of hair, and a certain thickness of hair needs to be wound around the cleaning roller brush before the hair can contact and rub against the auxiliary blade structure; the contact and cooperation between the main blade structure and the auxiliary blade structure realizes friction cutting of hair, which does not require the thickness of hair winding, and is more practical;

[0011] The main knife structure and the auxiliary knife structure are generally made of rigid materials. The rotation setting of the auxiliary knife structure enables the main knife structure to drive the auxiliary knife structure to rotate when passing through the auxiliary knife structure, so that the auxiliary knife structure moves toward the side of the cleaning roller brush and away from the cleaning roller brush, so that the main knife structure can smoothly pass through the auxiliary knife structure, that is, when the main knife structure and the prime auxiliary knife structure are in contact and cooperation, the rotation of the cleaning roller brush and the main knife structure is not affected, thereby ensuring the operation of the structure.

[0012] If the auxiliary knife structure is arranged above the cleaning roller brush, after the main knife structure completely passes through the auxiliary knife structure, the auxiliary knife structure can be reset under the action of gravity;

[0013] Or further, the anti-entanglement roller brush mechanism includes a reset member;

[0014] When the cleaning roller brush rotates along the first roller brush rotation direction to perform normal cleaning work, the main knife structure contacts the auxiliary knife structure and causes the auxiliary knife structure to rotate along the first knife rotation direction, and the auxiliary knife structure has a first auxiliary knife working position when it just contacts the main knife structure during the rotation along the first auxiliary knife rotation direction, and a second auxiliary knife working position when it is separated from the main knife structure;

[0015] The reset member acts on the auxiliary knife structure to prevent the auxiliary knife structure from rotating along the first auxiliary knife rotation direction, and makes the auxiliary knife structure have a tendency to move toward the first auxiliary knife working position side.

[0016] With the above structure, the reset member is arranged so that in the process of the main knife structure driving the auxiliary knife structure to rotate from the first auxiliary knife working position to the second auxiliary knife working position, the force acting on the auxiliary knife structure by the reset member needs to be overcome. Therefore, in the process of the main knife structure passing through the auxiliary knife structure, the acting force between the main knife structure and the auxiliary knife structure is greater, so that the friction between the hair wrapped around the cleaning roller brush and supported by the main knife structure and the auxiliary knife structure is also greater, which is conducive to frictional cutting of the hair;

[0017] Furthermore, the reset member is configured so that after the main knife structure has completely passed through the auxiliary knife structure, it can act on the auxiliary knife structure to move it to the first auxiliary knife working position, thereby resetting the auxiliary knife structure so that it can cooperate with the main knife structure to rub and cut hair next time.

[0018] Furthermore, the reset member is an elastic member, the elastic member has a first elastic end and a second elastic end, and the elastic member is deformed when the first elastic end and the second elastic end are close to each other;

[0019] Along the first knife rotation direction of the auxiliary knife structure, the two sides of the auxiliary knife structure respectively form a first auxiliary knife side surface and a second auxiliary knife side surface, and the first elastic end and the second elastic end of the elastic member respectively abut against the second auxiliary knife side surface and the inner wall of the roller brush mounting groove located on the side of the second auxiliary knife side surface.

[0020] With the above structure, the reset member adopts an elastic member so that the reset member can realize its function; specifically, when the cleaning roller brush rotates, the main knife structure will contact the auxiliary knife structure side of the auxiliary knife structure and drive the auxiliary knife structure to rotate from the first auxiliary knife working position to the second auxiliary knife working position. At this time, the auxiliary knife structure will act on the second elastic end of the elastic member to make it close to the first elastic end. Correspondingly, the elastic member will react on the auxiliary knife structure due to deformation to hinder its rotation to the second auxiliary knife working position; when the main knife structure has completely passed through the auxiliary knife structure, the force of the main knife structure acting on the auxiliary knife structure is removed, and the elastic member recovers under the action of elasticity, thereby driving the auxiliary knife structure to move back to the first auxiliary knife working position to achieve reset; specifically, the elastic member is a spring.

[0021] Furthermore, the auxiliary knife structure is provided with an elastic member matching through-hole penetrating the first auxiliary knife side surface and the second auxiliary knife side surface above or below the matching point with the first elastic end; the elastic member includes an elastic connecting part for connecting the first elastic end and the second elastic end, one end of the elastic connecting part is connected to the second elastic end, and the other end passes from the second auxiliary knife side surface through the top of the second auxiliary knife structure to the first auxiliary knife side surface, then bends and is connected to the second elastic end through the elastic member matching through-hole.

[0022] By adopting the above structure, the elastic member can be better arranged on the auxiliary knife structure, so that the elastic member can better act on the auxiliary knife structure; and the elastic member can be effectively prevented from being displaced, thereby reducing the effect of its force on the auxiliary knife structure; specifically, the elastic member is arranged in cooperation with the perforation on the auxiliary knife structure above the place where it cooperates with the first elastic end.

[0023] Furthermore, the reset member is provided with one or more;

[0024] When there is one reset member, the reset member is distributed at a position corresponding to the midline of the auxiliary knife structure;

[0025] When the number of the reset members is multiple and even, the multiple reset members are symmetrically distributed on both sides of the midline of the auxiliary knife structure, and the multiple reset members are spaced apart along the axis direction of the auxiliary knife structure.

[0026] When the number of the reset members is multiple and odd, one of the multiple reset members is distributed at the position corresponding to the center line of the auxiliary knife structure, the remaining reset members are symmetrically distributed on both sides of the center line of the auxiliary knife structure, and the multiple reset members are spaced apart along the axial direction of the auxiliary knife structure.

[0027] By adopting the above structure, the auxiliary knife structure is subjected to more balanced force under the action of the multiple reset members, so that the cooperation force between the various positions of the auxiliary knife structure and the main knife structure is more balanced, so as to facilitate frictional cutting of hair; because the auxiliary knife structure has a certain length, the above effect can be better when multiple reset members are provided.

[0028] Furthermore, along the first knife rotation direction of the auxiliary knife structure, the two sides of the auxiliary knife structure respectively form a first auxiliary knife side surface and a second auxiliary knife side surface, and the inner wall of the roller brush mounting groove is provided with abutment protrusions on the side protrusions of the first auxiliary knife side surface of the auxiliary knife structure, and when the auxiliary knife structure abuts against the abutment protrusions, the auxiliary knife structure is in the first auxiliary knife working position.

[0029] With the above structure, the setting of the abutment protrusion makes the structural setting more reasonable, so as to facilitate the resetting of the auxiliary knife structure; under the action of the resetting member, the auxiliary knife structure moves toward the working position side of the first auxiliary knife, and will eventually abut against the abutment protrusion to avoid the auxiliary knife structure from rotating too much, thereby realizing the resetting of the auxiliary knife structure, and the above structure is more reliable.

[0030] Furthermore, a mounting shaft is provided on the side of the auxiliary knife structure away from the cleaning roller brush, and along the extension direction of the auxiliary knife structure, both sides of the mounting shaft protrude from both sides of the auxiliary knife structure; along the axial direction of the cleaning roller brush, the inner walls on both sides of the roller brush mounting groove are recessed at the corresponding positions for installing the auxiliary knife structure and are matched with the two sides of the mounting shaft; the two sides of the mounting shaft are respectively rotatably engaged in the auxiliary knife mounting grooves on both sides.

[0031] By adopting the above structure, the two sides of the installation shaft cooperate with the auxiliary knife installation groove to realize the rotational installation of the auxiliary knife structure in the roller brush installation groove; the above structure is simple in structure, convenient for actual production, and reliable in operation.

[0032] Furthermore, the cleaning roller brush rotates along the first roller brush rotation direction during normal cleaning operation; along the first roller brush rotation direction, the roller brush mounting groove is provided with a comb tooth structure protruding in front of the auxiliary knife structure toward the cleaning roller brush side, and the comb tooth structure is extended along the axial direction of the roller brush mounting groove; when the cleaning roller brush rotates so that the main knife structure passes through the comb tooth structure, there is a gap between the side of the main knife structure facing the comb tooth structure and the side of the comb tooth structure facing the main knife structure;

[0033] The comb tooth structure is provided with a comb tooth groove on one side facing the cleaning roller brush and recessed toward the side away from the cleaning roller brush, and along the extension direction of the comb tooth structure, the comb tooth structure is provided with a plurality of comb tooth grooves arranged at intervals, and comb teeth are formed between two adjacent comb tooth grooves.

[0034] Along the rotation direction of the first roller brush, the comb tooth structure is arranged in front of the auxiliary knife structure, which can be understood as follows: when the cleaning roller brush rotates along the rotation direction of the first roller brush, a point on the cleaning roller brush first passes through the comb tooth structure and then passes through the auxiliary knife structure;

[0035] With the above structure, the arrangement of the comb tooth structure can reduce the entanglement of hair when the cleaning roller brush rotates, and can comb the hair entangled on the cleaning roller brush, so that the main blade structure and the auxiliary blade structure cooperate with each other to cut off the hair by friction;

[0036] Since the comb-tooth structure is located in front of the auxiliary blade structure along the rotation direction of the first roller brush, that is, the comb-tooth structure is located on the first auxiliary blade side surface of the auxiliary blade structure, the comb-tooth structure is formed as the abutting protrusion.

[0037] Further, along the rotation direction of the first roller brush, the comb tooth structure includes a first comb tooth side surface and a second comb tooth side surface, and along the direction from the comb tooth structure away from the cleaning roller brush to the cleaning roller brush, the first comb tooth side surface gradually inclines toward the rotation direction of the first roller brush.

[0038] By adopting the above structure, the comb tooth structure can better reduce the entanglement of hair when the cleaning roller brush rotates, and can better comb the hair entangled on the cleaning roller brush, so that the main knife structure and the auxiliary knife structure can cooperate and rub to cut off the hair.

[0039] Furthermore, a dust collecting chamber for collecting dust is provided in the mounting base, and the dust collecting chamber is provided with a dust inlet and an air duct opening, the dust inlet is connected to the roller brush mounting groove, and the air duct opening is connected to the air suction port of the fan.

[0040] With the above structure, when the cleaning roller brush rotates, the fan works at the same time, and air is sucked from the dust collecting chamber through the air duct opening, so that the dust collecting chamber is under negative pressure, and the external dust or small garbage is swept up by the cleaning roller brush and enters the dust collecting chamber through the dust inlet for collection; and the hair cut by friction under the cooperation of the main knife structure and the auxiliary knife structure also enters the dust collecting chamber through the dust inlet for collection.

[0041] Furthermore, the dust collecting chamber is movably provided with a dust inlet opening and closing component for opening and closing the dust inlet at the dust inlet, and when the fan draws air through the air duct opening, the dust inlet opening and closing component opens the dust inlet; when the fan stops drawing air through the air duct opening, the dust inlet opening and closing component closes the dust inlet.

[0042] With the above structure, when the fan is not working, the dust inlet opening and closing member closes the dust inlet to prevent the garbage in the dust collecting chamber from being discharged to the outside through the dust inlet; when the fan is working, the dust inlet opening and closing member opens the dust inlet to facilitate the garbage to enter the dust collecting chamber through the dust inlet; the above structure is reasonably designed.

[0043] Furthermore, the dust inlet opening and closing member is rotatably arranged in the dust collecting chamber.

[0044] With the above structure, when the fan is working to draw air from the dust collecting chamber so that the dust collecting chamber is at negative pressure, the dust inlet opening and closing member can automatically rotate under the action of the pressure difference to open the dust inlet; when the fan stops working, the dust inlet opening and closing member is reset under the action of gravity to close the dust inlet.

[0045] Furthermore, the mounting base is provided with an exhaust passage, one end of which is connected to the air duct opening, and the other end of which is connected to the air suction port of the fan.

[0046] The above structure makes the structural arrangement of the mounting base more reasonable and the internal space planning of the mounting base more reasonable, so as to facilitate the installation of the fan.

[0047] Furthermore, a filtering structure is provided at the air duct opening.

[0048] By adopting the above structure and the setting of the filtering structure, when the fan is working to draw air into the dust collecting chamber, the garbage in the dust collecting chamber can be effectively prevented from being sucked into the fan. The above structure is reasonably designed and reliable in operation. Specifically, the filtering structure adopts a filter net.

[0049] Further, the mounting base includes a mounting base body and a dust box having the dust collecting cavity, and the dust box is detachably mounted in the mounting base body.

[0050] With the above structure, the dust box is arranged in a detachable form, so that the user can empty the dust and clean the dust box; specifically, the roller brush installation groove is arranged in the installation base body.

[0051] Furthermore, the cleaning roller brush structure is detachable and can be installed in the roller brush installation groove.

[0052] The above structure is adopted to facilitate the user to replace and maintain the cleaning roller brush structure.

[0053] Furthermore, the cleaning roller brush structure comprises a first support member and a second support member, one end of the cleaning roller brush in the axial direction is fixedly connected to the first support member, and the other end is rotatably connected to the second support member;

[0054] A support through hole is provided on one axial end side wall of the roller brush mounting groove for the first support member to pass through and drive connected to the driving structure, and a support receiving groove is provided on the other end with an open bottom surface for receiving the second support member.

[0055] The above structure makes the structural design of the cleaning roller brush structure more reasonable and easy to replace; when installing, it is only necessary to insert the first support member through the support member through the support member hole to connect with the driving structure, and then place the second support member in the support member accommodating groove; when disassembling, just reverse the operation.

[0056] Furthermore, the anti-entanglement roller brush mechanism includes a cover plate that matches the opening of the roller brush mounting slot, the cover plate is removably arranged on one side of the bottom surface of the mounting base where the roller brush mounting slot is set, and the cover plate is provided with a roller brush exposure opening for exposing the cleaning roller brush.

[0057] With the above structure, the setting of the cover plate can prevent the cleaning roller brush structure from falling off from the roller brush installation groove, thereby ensuring reliable and stable operation.

[0058] Furthermore, the cleaning roller brush is a bristle roller brush; the main blade structure is a blade without an edge; the auxiliary blade structure is a rigid friction plate; specifically, the auxiliary blade structure is a stainless steel plate.

[0059] The above structure makes the structural design of the anti-entanglement roller brush mechanism more reasonable.

[0060] A cleaning device comprises a driving structure and the above-mentioned anti-tangling roller brush mechanism, wherein the mounting base forms a shell of the cleaning device, the driving structure is arranged in the shell and is connected to the cleaning roller brush to drive it to rotate.

[0061] By adopting the above structure and the anti-entanglement roller brush mechanism, the structure can be simplified while achieving the effect of cutting hair to prevent entanglement, so that the structure is simple, the operation is reliable, the actual production is convenient, and the cost is low.

[0062] Specifically, the cleaning device is a sweeping robot.

[0081] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0082] See also Figures 1 to 6The utility model provides an anti-hair entanglement roller brush mechanism, including an installation base 1 and a cleaning roller brush structure 2, the installation base 1 is provided with a roller brush installation groove 101 matching the cleaning roller brush structure 2, the cleaning roller brush structure 2 is installed in the roller brush installation groove 101; the cleaning roller brush structure 2 includes a cleaning roller brush 201 rotatable around its axis, the cleaning roller brush 201 is provided with a main knife structure 3, and the main knife structure 3 is extended along the axial direction of the cleaning roller brush 201; the roller brush installation groove 101 is provided with an auxiliary knife structure 4 opposite to the cleaning roller brush 201, and the auxiliary knife structure 4 is extended along the axial direction of the cleaning roller brush 201; when the cleaning roller brush 201 rotates so that the main knife structure 3 passes through the auxiliary knife structure 4, the side of the main knife structure 3 facing the auxiliary knife structure 4 is in contact with or clearance-fitted with the side of the auxiliary knife structure 4 facing the main knife structure 3.

[0083] With the above structure, when the cleaning roller rotates to perform cleaning work, the main blade structure 3 will rotate synchronously with the cleaning roller brush 201, so that the main blade structure 3 passes through the auxiliary blade structure 4 again and again; due to the contact fit or clearance fit between the main blade structure 3 and the auxiliary blade structure 4, the hair wrapped around the cleaning roller brush 201 is supported by the main blade structure 3 and rubs against the auxiliary blade structure 4 when passing through the auxiliary blade structure 4, thereby cutting off the hair and realizing the anti-winding function; the above structure can simplify the structure, make the structure simple, and have reliable operation, facilitate actual production, and have low cost.

[0084] Furthermore, the cleaning roller brush 201 rotates so that when the main blade structure 3 passes through the auxiliary blade structure 4, the side of the main blade structure 3 facing the auxiliary blade structure 4 contacts and cooperates with the side of the auxiliary blade structure 4 facing the main blade structure 3;

[0085] The auxiliary knife structure 4 is rotatably disposed in the roller brush installation groove 101 , and the rotation axis of the auxiliary knife structure 4 is located on a side of the auxiliary knife structure 4 away from the cleaning roller brush 201 and parallel to the axis of the cleaning roller brush 201 .

[0086] With the above structure, the contact and cooperation between the main knife structure 3 and the auxiliary knife structure 4 makes the cooperation between the main knife structure 3 and the auxiliary knife structure 4 more reasonable, which is convenient for friction cutting of hair; the clearance cooperation between the main knife structure 3 and the auxiliary knife structure 4 realizes friction cutting of hair, and a certain thickness of hair needs to be wound around the cleaning roller brush 201 before the hair can contact and rub against the auxiliary knife structure 4; the contact and cooperation between the main knife structure 3 and the auxiliary knife structure 4 realizes friction cutting of hair, which does not require the thickness of hair winding, and is more practical;

[0087] The main knife structure 3 and the auxiliary knife structure 4 are generally made of rigid materials. The rotation setting of the auxiliary knife structure 4 enables the main knife structure 3 to drive the auxiliary knife structure 4 to rotate when passing through the auxiliary knife structure 4, so that the auxiliary knife structure 4 moves toward the side of the cleaning roller brush 201 and away from the cleaning roller brush 201, so that the main knife structure 3 can smoothly pass through the auxiliary knife structure 4, that is, when the main knife structure 3 and the auxiliary knife structure 4 are in contact and cooperation, it does not affect the rotation of the cleaning roller brush 201 and the main knife structure 3, thereby ensuring the operation of the structure.

[0088] If the auxiliary blade structure 4 is disposed above the cleaning roller brush 201, after the main blade structure 3 completely passes through the auxiliary blade structure 4, the auxiliary blade structure 4 can be reset under the action of gravity;

[0089] Or further, the anti-entanglement brush mechanism includes a reset member 5;

[0090] When the cleaning roller brush 201 rotates along the first roller brush rotation direction to perform normal cleaning work, the main knife structure 3 contacts the auxiliary knife structure 4 and causes the auxiliary knife structure 4 to rotate along the first knife rotation direction, and the auxiliary knife structure 4 has a first auxiliary knife working position when it just contacts the main knife structure 3 and a second auxiliary knife working position when it separates from the main knife structure 3 during the process of rotating along the first auxiliary knife rotation direction;

[0091] The reset member 5 acts on the auxiliary knife structure 4 to prevent the auxiliary knife structure 4 from rotating along the first auxiliary knife rotation direction, and makes the auxiliary knife structure 4 have a tendency to move toward the first auxiliary knife working position side.

[0092] With the above structure, the reset member 5 is arranged so that in the process of the main knife structure 3 driving the auxiliary knife structure 4 to rotate from the first auxiliary knife working position to the second auxiliary knife working position, the force acting on the auxiliary knife structure 4 by the reset member 5 needs to be overcome. Therefore, in the process of the main knife structure 3 passing through the auxiliary knife structure 4, the acting force between the main knife structure 3 and the auxiliary knife structure 4 is greater, so that the friction between the hair wound on the cleaning roller brush 201 and supported by the main knife structure 3 and the auxiliary knife structure 4 is also greater, which is conducive to frictional cutting of the hair;

[0093] Furthermore, the reset member 5 is configured so that after the main knife structure 3 has completely passed through the auxiliary knife structure 4, it can act on the auxiliary knife structure 4 to move it to the first auxiliary knife working position, thereby resetting the auxiliary knife structure 4 so that it can cooperate with the main knife structure 3 to rub and cut off hair next time.

[0094] Furthermore, the reset member 5 is an elastic member 501, and the elastic member 501 has a first elastic end 5011 and a second elastic end 5012, and when the first elastic end 5011 and the second elastic end 5012 are close to each other, the elastic member 501 is deformed;

[0095] Along the first knife rotation direction of the auxiliary knife structure 4, the two sides of the auxiliary knife structure 4 respectively form a first auxiliary knife side surface 401 and a second auxiliary knife side surface 402, and the first elastic end 5011 and the second elastic end 5012 of the elastic member 501 respectively abut against the second auxiliary knife side surface 402 and the inner wall of the roller brush mounting groove 101 located on the side of the second auxiliary knife side surface 402.

[0096] With the above structure, the reset member 5 adopts an elastic member 501, so that the reset member 5 can realize its function; specifically, when the cleaning roller brush 201 rotates and works, the main knife structure 3 will contact the auxiliary knife structure 4 side of the auxiliary knife structure 4, and drive the auxiliary knife structure 4 to rotate from the first auxiliary knife working position to the second auxiliary knife working position, at this time, the auxiliary knife structure 4 will act on the second elastic end 5012 of the elastic member 501 to make it close to the first elastic end 5011, correspondingly, the elastic member 501 will react on the auxiliary knife structure 4 due to deformation to hinder it from rotating to the second auxiliary knife working position; when the main knife structure 3 completely passes through the auxiliary knife structure 4, the force of the main knife structure 3 acting on the auxiliary knife structure 4 is removed, and the elastic member 501 recovers under the action of elasticity, thereby driving the auxiliary knife structure 4 to move back to the first auxiliary knife working position to achieve reset; specifically, the elastic member 501 is a spring.

[0097] Furthermore, the auxiliary knife structure 4 is provided with an elastic member matching through hole 403 that passes through the first auxiliary knife side surface 401 and the second auxiliary knife side surface 402 above or below the matching position with the first elastic end 5011; the elastic member 501 includes an elastic connecting portion 5013 for connecting the first elastic end 5011 and the second elastic end 5012, one end of the elastic connecting portion 5013 is connected to the second elastic end 5012, and the other end passes from the second auxiliary knife side surface 402 through the top of the second auxiliary knife structure 4 to the first auxiliary knife side surface 401, then bends and is connected to the second elastic end 5012 through the elastic member matching through hole 403.

[0098] By adopting the above structure, the elastic member 501 can be better arranged on the auxiliary knife structure 4, so that the elastic member 501 can better act on the auxiliary knife structure 4; and the elastic member 501 can be effectively prevented from being displaced, thereby reducing the effect of its force on the auxiliary knife structure 4; specifically, the elastic member cooperates with the through hole 403 to be arranged on the auxiliary knife structure 4 above the place where it cooperates with the first elastic end 5011.

[0099] Further, the reset member 5 is provided with one or more;

[0100] When there is one reset member 5, the reset member 5 is distributed at a position corresponding to the midline of the auxiliary knife structure 4;

[0101] When the number of the reset members 5 is multiple and even, the multiple reset members 5 are symmetrically distributed on both sides of the center line of the auxiliary knife structure 4, and the multiple reset members 5 are spaced apart along the axis direction of the auxiliary knife structure 4.

[0102] When the number of the reset members 5 is multiple and odd, one of the multiple reset members 5 is distributed at the position corresponding to the center line of the auxiliary knife structure 4, the remaining reset members 5 are symmetrically distributed on both sides of the center line of the auxiliary knife structure 4, and the multiple reset members 5 are distributed at intervals along the axial direction of the auxiliary knife structure 4.

[0103] By adopting the above structure, the auxiliary knife structure 4 is subjected to more balanced force under the action of the multiple reset members 5, so that the cooperation force between each position of the auxiliary knife structure 4 and the main knife structure 3 is more balanced, so as to facilitate frictional cutting of hair; since the auxiliary knife structure 4 has a certain length, the above effect can be better when multiple reset members 5 are provided.

[0104] Furthermore, along the first knife rotation direction of the auxiliary knife structure 4, the two sides of the auxiliary knife structure 4 respectively form a first auxiliary knife side surface 401 and a second auxiliary knife side surface 402, and the inner wall of the roller brush mounting groove 101 is protruded on the side of the first auxiliary knife side surface 401 of the auxiliary knife structure 4 with abutment protrusion 6, and when the auxiliary knife structure 4 abuts against the abutment protrusion 6, the auxiliary knife structure 4 is in the first auxiliary knife working position.

[0105] With the above structure, the setting of the abutment protrusion 6 makes the structural setting more reasonable, so as to facilitate the resetting of the auxiliary knife structure 4; under the action of the resetting member 5, the auxiliary knife structure 4 moves toward the first auxiliary knife working position side, and will eventually abut against the abutment protrusion 6 to prevent the auxiliary knife structure 4 from rotating too much, thereby realizing the resetting of the auxiliary knife structure 4, and the above structure is more reliable.

[0106] Furthermore, a mounting shaft 404 is provided on the side of the auxiliary knife structure 4 away from the cleaning roller brush 201, and along the extension direction of the auxiliary knife structure 4, both sides of the mounting shaft 404 protrude from both sides of the auxiliary knife structure 4; along the axial direction of the cleaning roller brush 201, the inner walls on both sides of the roller brush mounting groove 101 are recessed at the corresponding positions for installing the auxiliary knife structure 4 and are provided with auxiliary knife mounting grooves 1011 matching the two sides of the mounting shaft 404; the two sides of the mounting shaft 404 are respectively rotatably engaged in the auxiliary knife mounting grooves 1011 on both sides.

[0107] With the above structure, the two sides of the mounting shaft 404 cooperate with the auxiliary knife mounting groove 1011 to realize the rotational installation of the auxiliary knife structure 4 in the roller brush mounting groove 101; the above structure is simple in structure, convenient for actual production, and reliable in operation.

[0108] Furthermore, the cleaning roller brush 201 rotates along the first roller brush rotation direction during normal cleaning operation; along the first roller brush rotation direction, the roller brush mounting groove 101 is provided with a comb tooth structure 7 protruding in front of the auxiliary knife structure 4 toward the cleaning roller brush 201 side, and the comb tooth structure 7 is extended along the axial direction of the roller brush mounting groove 101; when the cleaning roller brush 201 rotates so that the main knife structure 3 passes through the comb tooth structure 7, there is a gap between the side of the main knife structure 3 facing the comb tooth structure 7 and the side of the comb tooth structure 7 facing the main knife structure 3;

[0109] The comb tooth structure 7 is provided with a comb tooth groove 701 which is recessed on one side facing the cleaning roller brush 201 and away from the cleaning roller brush 201 , and along the extension direction of the comb tooth structure 7 , the comb tooth structure 7 is provided with a plurality of the comb tooth grooves 701 which are arranged at intervals, and comb teeth 702 are formed between two adjacent comb tooth grooves 701 .

[0110] Along the rotation direction of the first roller brush, the comb tooth structure 7 is arranged in front of the auxiliary knife structure 4, which can be understood as follows: when the cleaning roller brush 201 rotates along the rotation direction of the first roller brush, a point on the cleaning roller brush 201 first passes through the comb tooth structure 7 and then passes through the auxiliary knife structure 4;

[0111] With the above structure, the arrangement of the comb tooth structure 7 can reduce the entanglement of hair when the cleaning roller brush 201 rotates, and can comb the hair entangled on the cleaning roller brush 201, so that the main blade structure 3 and the auxiliary blade structure 4 cooperate to rub and cut off the hair;

[0112] Since the comb tooth structure 7 is located in front of the auxiliary blade structure 4 along the rotation direction of the first roller brush, that is, the comb tooth structure 7 is located on the first auxiliary blade side surface 401 side of the auxiliary blade structure 4, the comb tooth structure 7 is formed as the abutting protrusion 6.

[0113] Furthermore, along the rotation direction of the first roller brush, the comb tooth structure 7 includes a first comb tooth side 703 and a second comb tooth side 704, and along the direction from the comb tooth structure 7 away from the side of the cleaning roller brush 201 to the side close to the cleaning roller brush 201, the first comb tooth side 703 gradually tilts toward the rotation direction of the first roller brush.

[0114] By adopting the above structure, the comb tooth structure 7 can better reduce the entanglement of hair when the cleaning roller brush 201 rotates, and can better comb the hair entangled on the cleaning roller brush 201, so that the main knife structure 3 and the auxiliary knife structure 4 can cooperate and rub to cut off the hair.

[0118] With the above structure, when the fan 100 is not working, the dust inlet opening and closing member 8 closes the dust inlet 1021 to prevent the garbage in the dust collecting chamber 102 from being discharged to the outside through the dust inlet 1021; when the fan 100 is working, the dust inlet opening and closing member 8 opens the dust inlet 1021 to facilitate the garbage to enter the dust collecting chamber 102 through the dust inlet 1021; the above structure is reasonably designed.

[0119] Furthermore, the dust inlet opening and closing member 8 is rotatably disposed in the dust collecting chamber 102 .

[0120] With the above structure, when the fan 100 is working to draw air from the dust collecting chamber 102 so that the dust collecting chamber 102 is at negative pressure, the dust inlet opening and closing member 8 can automatically rotate under the action of the pressure difference to open the dust inlet 1021; when the fan 100 stops working, the dust inlet opening and closing member 8 is reset under the action of gravity to close the dust inlet 1021.

[0124] By adopting the above structure, the setting of the filtering structure 9 can effectively prevent the garbage in the dust collecting chamber 102 from being sucked into the fan 100 when the fan 100 is working to draw air into the dust collecting chamber 102. The above structure is reasonably designed and reliable in operation. Specifically, the filtering structure 9 adopts a filter net.
