Description

[Technical Field]

[0001] This application claims priority to a Chinese patent application bearing application number "202223054347.3" and entitled "Hair Cutting Assembly and Cleaning Device" filed with the State Intellectual Property Office of the People's Republic of China on November 17, 2022, the entire contents of which are incorporated herein by reference.

[0002] FIELD OF THE INVENTION This application relates to the technical field of cleaning appliances, and more particularly to hair cutting assemblies and cleaning appliances. [Background technology]

[0003] Currently, cleaning appliances such as vacuum cleaners are widely used and are gradually becoming more common in homes. The main working part of the cleaning head of a vacuum cleaner is a rotating roller brush, which comes into contact with the ground and knocks and sweeps up dust on the ground. However, long, thin fibrous debris such as hair tends to get entangled in the roller brush, which affects the cleaning effect of the roller brush and makes cleaning difficult. Summary of the Invention [Problem to be solved by the invention]

[0004] In cleaning devices of the related art, fibrous debris tangled in a roller brush is cut with a blade, which disentangles the debris and sucks it up. However, when the cleaning device performs cleaning work, the debris rotating with the roller brush worsens damage to the blade and affects the blade's ability to cut fibrous debris.

[0005] SUMMARY OF THE INVENTION In order to solve or ameliorate at least one of the above technical problems, one object of the present application is to provide a hair-cutting assembly.

[0006] Another object of the present application is to provide a cleaning appliance having the above hair-cutting assembly. [Means for solving the problem]

[0007] In order to achieve the above object, a first aspect of the present application provides a hair-cutting assembly including a housing, a roller brush connected to the housing and rotatable relative to the housing about a rotation axis, a blade assembly connected to the housing, and comb tines connected to the housing, wherein the blade assembly and the comb tines are adjacent to each other in the circumferential direction of the roller brush, and when a plane on which the rotation axis is located rotates together with the roller brush in a first rotation direction, the plane passes through the comb tines and the blade assembly in sequence.

[0008] According to the embodiment of the hair-cutting assembly provided by the present application, when the dirt rotates along the roller brush in the direction of rotation, it first comes into contact with the comb teeth, which capture and cut off some of the dirt, and then the blade assembly cuts off the dirt that has adhered to or become entangled in the roller brush. The provision of the comb teeth can greatly protect the blade assembly, reduce damage to the blade assembly caused by dirt, ensure the effective use of the blade assembly, and be advantageous in improving the cutting effect of fibrous dirt by the blade assembly.

[0009] Specifically, the hair-cutting assembly includes a housing, a roller brush, a blade assembly, and comb teeth. Here, the roller brush, the blade assembly, and the comb teeth are all connected to the housing, which mainly serves as a mounting carrier. Furthermore, the roller brush is rotatable relative to the housing about a rotation axis. Optionally, the roller brush includes a roller and multiple rows of bristles provided on the circumferential side wall of the roller. The rotation axis of the roller brush can be understood as the rotation axis of the roller. The rotation of the roller brush actually refers to the roller driving the bristles to rotate. When the cleaning device performs cleaning work, the roller brush comes into contact with the ground, and the bristles of the roller brush knock dust off the ground, sweeping up the dirt, and rolling it into the housing.

[0010] Further, a blade assembly is connected to the housing. Optionally, the blade assembly includes a fixed blade and a movable blade. The fixed blade is fixed relative to the housing. The movable blade is movable relative to the fixed blade. Optionally, the movable blade abuts against the fixed blade. Relative movement between the movable blade and the fixed blade creates an effective shearing action to cut fibrous debris (e.g., hair tangled in the roller brush). Optionally, the housing includes a mounting housing, a first support housing, and a second support housing. The roller brush is connected to the mounting housing and is rotatable relative to the mounting housing about a rotation axis. The fixed blade is connected to the first support housing, and the movable blade is connected to the second support housing. The first support housing is connected to the mounting housing, and the second support housing is connected to the mounting housing. The first support housing and the mounting housing are connected by adhesive or welding, etc., and the second support housing and the mounting housing are connected by adhesive or welding, etc.

[0011] Furthermore, the blade assembly and the comb teeth are adjacent to each other in the circumferential direction of the roller brush. The blade assembly and the comb teeth are located on the same side of the plane on which the rotation axis of the roller brush is located. As the plane on which the rotation axis of the roller brush is located rotates together with the roller brush in a first rotational direction, the plane passes through the comb teeth and the blade assembly in sequence. As debris rotates together with the roller brush in its rotational direction, it first comes into contact with the comb teeth, which capture and cut off some of the debris. The blade assembly then cuts off any debris that has adhered to or become entangled with the roller brush. The provision of the comb teeth significantly protects the blade assembly, reduces damage to the blade assembly caused by debris, ensures the effective use of the blade assembly, and is advantageous in improving the blade assembly's effectiveness in cutting fibrous debris.

[0012] A second aspect of the present application provides a cleaning appliance including a hair-cutting assembly according to any of the above embodiments; a first drive member connected to the roller brush of the hair-cutting assembly and used to drive the roller brush to rotate about a rotation axis; a second drive member connected to the movable blade of the hair-cutting assembly and used to drive the movable blade to move relative to the fixed blade of the hair-cutting assembly; and a controller connected to the first drive member and the second drive member.

[0013] According to an embodiment of the cleaning device of the present application, the cleaning device includes the hair-cutting assembly of any of the above embodiments, a first drive member, and a second drive member. Specifically, the first drive member is connected to the roller brush of the hair-cutting assembly and is used to drive the roller brush to rotate about its rotation axis. The first drive member drives the roller brush to rotate along a first rotation direction or a second rotation direction. Selectively, when the roller brush rotates along the first rotation direction, the roller brush rotates forward, and when the roller brush rotates along the second rotation direction, the roller brush rotates backward. When the cleaning device performs cleaning work, the roller brush comes into contact with the ground, and the bristles of the roller brush knock dust off the ground, sweeping up the dirt and trapping it in the cavity of the housing.

[0014] Furthermore, the second drive member is connected to the movable blade of the hair-cutting assembly, and the second drive member is used to drive the movable blade to move relative to the fixed blade of the hair-cutting assembly, the relative movement between the movable blade and the fixed blade creating an effective shearing action to cut fibrous debris (e.g., hair tangled in the roller brush), thereby enhancing the cleaning effect.

[0015] Furthermore, a controller is connected to the first driving member, and the controller is connected to the second driving member, and the control method of the controller is as follows: when it is determined that the roller brush is in an operating state, the controller controls the movable blade to be in a constant moving state, or when it is determined that the roller brush is in an operating state, the controller controls the movable blade to move intermittently, or when it is determined that the roller brush is in an operating state, the controller controls the movable blade to be in a moving state and to stop moving the movable blade after a time threshold, or when it is determined that the roller brush is not in an operating state, the controller controls the movable blade to be in a moving state, or when controlling the movable blade to be in a moving state, the controller controls the roller brush to rotate in a reverse direction.

[0016] The cleaning appliance includes a hair-cutting assembly according to any of the first aspects above, and therefore has the beneficial effects of any of the above embodiments, and will not be described in detail here.

[0017] Additional aspects and advantages of the present embodiments will be set forth in part in the description that follows, or may be learned by practice of the present invention. [Brief explanation of the drawings]

[0019] In order to more clearly understand the above objects, features and advantages of the present application, the present application will be described in more detail below with reference to the drawings and specific embodiments. It should be noted that, if there is no conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0020] In the following description, numerous specific details are set forth to provide a thorough understanding of the present application, but the scope of protection of the present application is not limited to the specific embodiments disclosed below, as the present application may be implemented in other ways different from those described.

[0021] A hair-cutting assembly 100 and a cleaning device 200 according to some embodiments of the present application will now be described with reference to FIGS.

[0022] In one embodiment of the present application, as shown in FIG. 1, a hair-cutting assembly 100 includes a housing 110, a roller brush 120, a blade assembly 130, and comb teeth 140. Here, the roller brush 120, the blade assembly 130, and the comb teeth 140 are all connected to the housing 110, which mainly functions as a mounting carrier. Furthermore, the roller brush 120 is rotatable relative to the housing 110 about a rotation axis. Optionally, as shown in FIGS. 1, 2, and 3, the roller brush 120 includes a roller 121 and multiple rows of bristles 122 provided on a circumferential side wall of the roller 121. The rotation axis of the roller brush 120 can be understood to be the rotation axis of the roller 121. The rotation of the roller brush 120 actually occurs when the roller 121 drives the bristles 122 to rotate. When the cleaning device 200 performs cleaning work, the roller brush 120 comes into contact with the ground, and the brush bristles 122 of the roller brush 120 knock dust off the ground, sweep up the dirt, and catch it in the housing 110.

[0023] Further, the blade assembly 130 is connected to the housing 110. Optionally, as shown in FIG. 1 , the blade assembly 130 includes a fixed blade 131 and a movable blade 132. The fixed blade 131 is fixed relative to the housing 110. The movable blade 132 is movable relative to the fixed blade 131. Optionally, the movable blade 132 abuts against the fixed blade 131. Relative movement between the movable blade 132 and the fixed blade 131 creates an effective shearing action to cut fibrous debris (e.g., hair entangled in the roller brush 120). Optionally, the housing 110 includes a mounting housing 111, a first support housing 112, and a second support housing 113. The roller brush 120 is connected to the mounting housing 111, and the roller brush 120 is rotatable relative to the mounting housing 111 about a pivot axis. The fixed blade 131 is connected to the first support housing 112, and the movable blade 132 is connected to the second support housing 113. The first support housing 112 is connected to the mounting housing 111, and the second support housing 113 is connected to the mounting housing 111. The connection between the first support housing 112 and the mounting housing 111 is by adhesive bonding or welding, and the connection between the second support housing 113 and the mounting housing 111 is by adhesive bonding or welding.

[0024] Furthermore, the blade assembly 130 and the comb teeth 140 are adjacent to each other in the circumferential direction of the roller brush 120. The blade assembly 130 and the comb teeth 140 are located on the same side of the plane on which the rotation axis of the roller brush 120 is located. When the plane on which the rotation axis of the roller brush 120 is located rotates together with the roller brush 120 in the first rotation direction, the plane passes through the comb teeth 140 and the blade assembly 130 in sequence. As the debris rotates together with the roller brush 120 in the rotation direction, it first comes into contact with the comb teeth 140, which capture and cut off some of the debris. The blade assembly 130 then cuts off any debris that has adhered to or become entangled with the roller brush 120. The installation of the comb teeth 140 significantly protects the blade assembly 130, reduces damage to the blade assembly 130 caused by debris, ensures the effective use of the blade assembly 130, and is advantageous in improving the cutting effect of the blade assembly 130 on fibrous debris.

[0025] 1 , the blade assembly 130 includes a fixed blade 131 and a movable blade 132. Specifically, the fixed blade 131 is connected to the housing 110. The fixed blade 131 is fixed relative to the housing 110. Furthermore, the movable blade 132 is connected to the housing 110. The movable blade 132 is movable relative to the fixed blade 131. Optionally, the movable blade 132 has a first operating position and a second operating position. The movable blade 132 can move from the first operating position to the second operating position, or from the second operating position to the first operating position, thereby moving the movable blade 132 closer to or further away from the roller brush 120. The movable blade 132 moves relative to the fixed blade 131 between the first and second operating positions, and the relative movement between the movable blade 132 and the fixed blade 131 creates an effective shearing action to cut fibrous debris (e.g., hair tangled in the roller brush 120).

[0026] In some embodiments, the movable blade 132 and the fixed blade 131 are selectively adjacent to each other in the circumferential direction, with the movable blade 132 being disposed on one side of the fixed blade 131 in the circumferential direction of the roller brush 120 and the comb teeth 140 being disposed on the other side of the fixed blade 131 in the circumferential direction of the roller brush 120. In other words, the fixed blade 131 is located between the movable blade 132 and the comb teeth 140. When the plane on which the rotation axis of the roller brush 120 is located rotates together with the roller brush 120 in the first rotation direction, the plane passes through the comb teeth 140, the fixed blade 131 of the blade assembly 130, and the movable blade 132 of the blade assembly 130 in that order. When dust rotates together with the roller brush 120 in the rotation direction, it first comes into contact with the comb teeth 140, then the fixed blade 131, and finally the movable blade 132. The comb teeth 140 and fixed blade 131 capture and cut off a portion of the dirt, and then the relative movement between the movable blade 132 and the fixed blade 131 cuts off the dirt that has adhered to or become entangled in the roller brush 120. The comb teeth 140 and fixed blade 131 greatly protect the movable blade 132, reducing damage to the movable blade 132 caused by dirt, ensuring the effective use time of the blade assembly 130 and advantageously improving the cutting effect of fibrous dirt by the blade assembly 130.

[0027] In some embodiments, optionally, at least one fixed blade 131 is provided on one side of the movable blade 132 in the circumferential direction of the roller brush 120, and at least one fixed blade 131 is provided on the other side of the movable blade 132 in the circumferential direction of the roller brush 120. When the plane on which the rotation axis of the roller brush 120 is located rotates together with the roller brush 120 in the second rotation direction, this plane passes through at least one fixed blade 131 before passing through the movable blade 132. The second rotation direction is opposite to the first rotation direction. At least one fixed blade 131 is provided on each side of the movable blade 132 in the circumferential direction of the roller brush 120. Optionally, the first rotation direction is forward rotation, and the second rotation direction is reverse rotation. Regardless of whether the roller brush 120 rotates forward or backward, when the plane on which the rotation axis of the roller brush 120 is located rotates together with the roller brush 120, this plane will pass by at least one fixed blade 131 and one movable blade 132 in sequence, ensuring that the dust rotating together with the roller brush 120 first comes into contact with the stationary fixed blade 131, protecting the movable blade 132 and reducing damage caused by the dust to the movable blade 132. Taking into consideration the cutting effect of the fixed blade 131 and the movable blade 132 on fibrous dust, the size of the space occupied, the degree of protection for the movable blade 132, costs, and other factors, the number of fixed blades 131 and the number of movable blades 132 can be flexibly determined according to actual needs.

[0028] In another embodiment, at least one comb tooth 140 is provided on the fixed blade 131 on the side opposite the movable blade 132, and at least one comb tooth 140 is provided on the movable blade 132 on the side opposite the fixed blade 131. When the plane on which the rotation axis of the roller brush 120 is located rotates together with the roller brush 120 in the second rotation direction, the plane passes through at least one comb tooth 140 before passing through the fixed blade 131 or the movable blade 132. The second rotation direction is opposite to the first rotation direction. At least one comb tooth 140 is provided on each of both sides of the blade assembly 130 in the circumferential direction of the roller brush 120. Optionally, the first rotation direction is forward rotation, and the second rotation direction is reverse rotation. Regardless of whether the roller brush 120 rotates forward or backward, when the plane on which the rotation axis of the roller brush 120 is located rotates together with the roller brush 120, the plane passes through at least one comb tooth 140 and the blade assembly 130 in sequence, ensuring that dust rotating together with the roller brush 120 first comes into contact with the comb tooth 140, protecting the blade assembly 130 and reducing damage to the blade assembly 130 caused by dust. The comb teeth 140 can be flexibly installed according to actual needs, taking into account the degree of protection for the blade assembly 130, the size of the space occupied, cost, and other factors.

[0029] In some embodiments, when the plane on which the rotation axis of the roller brush 120 is located passes through the comb teeth 140, the roller brush 120 can be rotated by a first angle so that the plane on which the rotation axis of the roller brush 120 is located passes through the blade assembly 130. By controlling the first angle to 25 degrees or less, on the one hand, there is a certain gap between the comb teeth 140 and the blade assembly 130, which ensures the effectiveness of the comb teeth 140 themselves and the fixed blade 131 themselves in capturing and cutting off dirt, and on the other hand, the gap between the comb teeth 140 and the blade assembly 130 is not excessive, which ensures that dirt rotating with the roller brush 120 first comes into contact with the comb teeth 140, protecting the blade assembly 130 and reducing damage to the blade assembly 130 caused by the dirt.

[0030] Optionally, a movable blade 132 and comb teeth 140 are provided on both sides of the fixed blade 131. The circumferential angle formed by one end of the comb teeth 140 facing the roller brush 120 and one end of the fixed blade 131 facing the roller brush 120 and the rotation axis of the roller brush 120 is 25 degrees or less. In other words, the relative positions of the comb teeth 140 and the fixed blade 131 are offset by 25 degrees, thereby providing an appropriate space and making it easier to collect objects such as dust and hair.

[0031] In another embodiment, the distance between the comb teeth 140 and the fixed blade 131 is 7 mm or less. By controlling the distance between the comb teeth 140 and the fixed blade 131 to 7 mm or less, the distance between the comb teeth 140 and the blade assembly 130 is prevented from becoming excessively large, and dust rotating with the roller brush 120 first comes into contact with the comb teeth 140, protecting the first blade teeth of the fixed blade 131 and reducing damage to the blade assembly 130 caused by dust.

[0032] Furthermore, the fixed blade 131 has a plurality of first blade teeth, and the comb teeth 140 have a plurality of second blade teeth. By setting the number of second blade teeth of the comb teeth 140 to be multiple and matching the number of second blade teeth to the number of first blade teeth, it is advantageous to improve the dust capturing and cutting effect of the comb teeth 140 itself. Furthermore, each second blade tooth is installed corresponding to one first blade tooth of the fixed blade 131, ensuring that the comb teeth 140 can protect each comb tooth 140 of the fixed blade 131, further reducing damage to the movable blade 132 by dust, and improving the cutting effect of the blade assembly 130 on fibrous dust.

[0033] 1 , the tooth tip side of the fixed blade 131 is selectively arranged toward the roller brush 120, and the tooth tip side of the movable blade 132 is arranged toward the roller brush 120. By arranging the tooth tip side of the blade toward the roller brush 120, some of the dirt adhering to or entangled in the roller brush 120 can be cut off by the blade on the tooth tip side of the blade, thereby releasing the entanglement and sucking it up, which is advantageous for improving the cleaning effect of the cleaning device 200. Furthermore, the movable blade 132 has a first operating position and a second operating position, and the movable blade 132 can move from the first operating position to the second operating position or from the second operating position to the first operating position. The movable blade 132 moves along the rotation axis of the roller brush 120 to shear it. The movable blade 132 moves relative to the fixed blade 131 between a first operating position and a second operating position, and the relative movement between the movable blade 132 and the fixed blade 131 forms an effective shearing action, which is advantageous for cutting fibrous debris (e.g., hair tangled in the roller brush 120) and increasing the cutting effect of the blade assembly 130, further enhancing the cleaning effect of the cleaning device 200.

[0034] Furthermore, the distance between the tooth tip side of the fixed blade 131 and the rotation axis of the roller brush 120 is a first distance. The distance between the tooth tip side of the movable blade 132 in the first operating position and the rotation axis of the roller brush 120 is a second distance. The distance between the tooth tip side of the movable blade 132 in the second operating position and the rotation axis of the roller brush 120 is a third distance. The second distance is larger than the first distance, i.e., the distance between the tooth tip side of the movable blade 132 in the first operating position and the rotation axis of the roller brush 120 is larger than the distance between the tooth tip side of the fixed blade 131 and the rotation axis of the roller brush 120. The third distance is larger than the first distance, i.e., the distance between the tooth tip side of the movable blade 132 in the second operating position and the rotation axis of the roller brush 120 is larger than the distance between the tooth tip side of the fixed blade 131 and the rotation axis of the roller brush 120. In other words, whether the movable blade 132 is in the first operating position or the second operating position, the distance between its tooth tip side and the rotation axis of the roller brush 120 is greater than the distance between the tooth tip side and the rotation axis of the fixed blade 131. Dust that adheres to or becomes entangled in the roller brush 120 first comes into contact with the stationary fixed blade 131, which is advantageous in protecting the movable blade 132 and reducing damage to the movable blade 132 caused by dust. The tooth tip side of the fixed blade 131 protrudes further than the tooth tip side of the movable blade 132 (closer to the roller brush 120), preventing injury to the human body from coming into direct contact with the cutting edge of the movable blade 132.

[0035] In another embodiment, the distance between the comb teeth 140 and the rotation axis of the roller brush 120 is a fourth distance, which is greater than the first distance. The distance between the comb teeth 140 and the rotation axis of the roller brush 120 is greater than the distance between the tooth tips of the fixed blade 131 and the rotation axis of the roller brush 120. In other words, the tooth tips of the fixed blade 131 protrude beyond the comb teeth 140 (are closer to the roller brush 120). On the one hand, this ensures that the fixed blade 131 itself can cut off dust that has adhered to or become entangled in the roller brush 120, and on the other hand, this is advantageous for protecting the movable blade 132 and reducing damage to the movable blade 132 caused by dust.

[0036] In another embodiment, the second spacing is greater than the third spacing, i.e., the spacing between the tip of the movable blade 132 in the first operating position and the rotation axis of the roller brush 120 is greater than the spacing between the tip of the movable blade 132 in the second operating position and the rotation axis of the roller brush 120. When the movable blade 132 moves from the first operating position to the second operating position, the movable blade 132 gradually approaches the roller brush 120, and when the movable blade 132 moves from the second operating position to the first operating position, the movable blade 132 gradually moves away from the roller brush 120. By making the difference between the third distance and the first distance 0.1 mm or more, i.e., by making the difference between the third distance and the first distance 0.1 mm or more, on the one hand, it is ensured that the third distance is larger than the first distance, so that dirt adhering to or entangled in the roller brush 120 first comes into contact with the stationary fixed blade 131, thereby protecting the movable blade 132, and on the other hand, it is ensured that the difference between the third distance and the first distance is not excessive, thereby ensuring the effectiveness of the movable blade 132 in cutting fibrous dirt.

[0037] In one embodiment of the present application, as shown in Figures 4, 5, 6 and 7, a cleaning device 200 includes the hair-cutting assembly 100 of any of the above embodiments, a first driving member 211 and a second driving member 212. Specifically, the first driving member 211 is connected to the roller brush 120 of the hair-cutting assembly 100 and is used to drive the roller brush 120 to rotate about its rotation axis. The first driving member 211 drives the roller brush 120 to rotate along a first rotation direction or a second rotation direction. Selectively, when the roller brush 120 rotates along the first rotation direction, the roller brush 120 rotates forward, and when the roller brush 120 rotates along the second rotation direction, the roller brush 120 rotates backward. When the cleaning device 200 performs cleaning work, the roller brush 120 comes into contact with the ground, and the brush bristles 122 of the roller brush 120 strike dust on the ground, sweep up the dirt, and catch it in the cavity 114 of the housing 110 .

[0038] Furthermore, the second driving member 212 is connected to the movable blade 132 of the hair-cutting assembly 100, and the second driving member 212 is used to drive the movable blade 132 to move relative to the fixed blade 131 of the hair-cutting assembly 100. The relative movement between the movable blade 132 and the fixed blade 131 creates an effective shearing action to cut fibrous debris (e.g., hair tangled in the roller brush 120), thereby enhancing the cleaning effect.

[0039] Furthermore, the controller 220 is connected to the first driving member 211, and the controller 220 is connected to the second driving member 212. The control method of the controller 220 is as follows: if it is determined that the roller brush 120 is in an operating state, it controls the movable blade 132 to be in a constant moving state, or if it is determined that the roller brush 120 is in an operating state, it controls the movable blade 132 to move intermittently, or if it is determined that the roller brush 120 is in an operating state, it controls the movable blade 132 to be in a moving state and to stop moving the movable blade 132 after a time threshold, or if it is determined that the roller brush 120 is not in an operating state, it controls the movable blade 132 to be in a moving state, or if it controls the movable blade 132 to be in a moving state, it controls the roller brush 120 to rotate in a reverse direction.

[0040] 6 and 7 , the cleaning device 200 optionally further includes a detection device 230. Specifically, the detection device 230 is connected to the controller 220. The detection device 230 is used to detect the amount of dirt attached to or entangled in the roller brush 120. The controller 220 can control the movement state of the movable blade 132 based on the information on the amount of dirt provided by the detection device 230. A specific control method is as follows: When the controller 220 determines that the roller brush 120 is in an operating state and determines based on the detection device 230 that the amount of dirt on the roller brush 120 is greater than a first threshold, the controller 220 controls the movable blade 132 to be in a moving state; alternatively, when the controller 220 determines based on the detection device 230 that the amount of dirt on the roller brush 120 is less than a second threshold, the controller 220 controls the movable blade 132 to stop moving. The second threshold is equal to or less than the first threshold. It can be understood that the first threshold may be the same as or different from the second threshold.
