Description

TECHNICAL FIELD

[0001] The present application relates to a hair cutting device, a cleaning device and a base station, and belongs to the technical field of cleaning devices. BACKGROUND

[0002] The cleaning device mainly uses the rotation of the roller brush at the bottom of the cleaning device to clean the garbage on the ground. When the cleaning device is working, the hair on the ground is easy to entangle on the roller brush, affecting the cleaning effect of the roller brush. Moreover, as the roller brush rotates, the hair on the roller brush will entangle more and more tightly, causing the roller brush to be deformed, which will cause damage to the roller brush motor and affect the service life of the base station if not cleaned in time.

[0003] Because the hair is relatively soft and entangled on the roller brush, and the bristles and rubber strips on the roller brush cannot fix or support the hair, the existing hair cleaning device has poor hair cleaning effect. In addition, multiple motors need to be set in the existing sweeping robot for driving, which has complex structure and low reliability.

[0027] In order to make the object, technical scheme and advantages of the application more clear, the application is described in detail below with reference to the drawings and specific embodiments.

[0028] Here, it should be noted that, in order to avoid the unnecessary details from blurring the application, only the structures and / or processing steps closely related to the scheme of the application are shown in the drawings, and other details not closely related to the application are omitted.

[0029] In addition, it should be further noted that the term "comprise", "include" or any other variant thereof is intended to cover the non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0030] As Figures 1 to 5 shown in the drawings, the present application discloses a cleaning device (not shown in the drawings) and a base station (not shown in the drawings) cooperating with the cleaning device. The base station is provided with a hair cutting device 100 capable of cutting the hair in the roller brush of the cleaning device. It should be noted that when the cleaning device returns to the base station, the hair cutting device 100 works and cuts in the axial direction of the roller brush, and when the cleaning device goes out, the hair cutting device 100 stops working and is retracted.

[0031] It can be understood that the hair cutting device 100 can also be provided in the cleaning device and cut the hair in the roller brush during the operation gap of the cleaning device, so as not to affect the operation efficiency of the cleaning device.

[0032] For the sake of clarity, the following description is based on the hair cutting device 100 being provided in the base station, but those skilled in the art will know that this is not limiting.

[0033] As Figures 1 to 5 shown in the drawings, in this embodiment, the base station includes a base 101, the base 101 has a ramp 102 for the cleaning device to travel, the ramp 102 is provided with a speed bump for increasing the friction with the cleaning device, so that the cleaning device can stop on the ramp 102, the ramp 102 is provided with an opening 103, the hair cutting device 100 is provided on the base 101 and located below the opening 103, so as to facilitate the contact with the cleaning element through the opening 103, thereby cleaning the hair on the cleaning element. Of course, in other embodiments, the base 101 can also not be provided with the ramp 102, but has a parking position for the cleaning device to park, at this time, the opening 103 can also be provided at the parking position.

[0034] The hair cutting device 100 includes a housing 10, a driving assembly 20, a blade assembly 30 and a guide 40, the driving assembly 20, the blade assembly 30 and the guide 40 are all provided in the housing 10. The housing 10 is provided below the opening 103 to improve the aesthetics of the base 101.

[0035] The housing 10 has a rectangular structure, and has a length direction parallel to the blade assembly 30 and a width direction perpendicular to the length direction. The housing 10 comprises a bottom plate 11 and a side wall 12 surrounding the bottom plate 11, and the bottom plate 11 and the side wall 12 are formed with a receiving groove 13. The driving assembly 20, the blade assembly 30 and the guide 40 are received in the receiving groove 13. In addition, the receiving groove 13 can also collect the hair cut by the blade assembly 30, so as to facilitate the hair to be sucked by a suction device (not shown) and improve the cleaning efficiency. The peripheral wall of the housing 10 extends outwardly and is provided with a fixing portion (not shown), and the housing 10 is fixedly connected with a base station or a cleaning device through the fixing portion, so that the hair cutting device 100 can be fixedly connected with the base station or the cleaning device.

[0036] The driving assembly 20 is fixed on the bottom plate 11 of the housing 10. The driving assembly 20 comprises a driving device and a driving shaft 21. Preferably, the driving device is an electric motor 22, and the driving shaft 21 is located on the same straight line as a motor shaft of the electric motor 22, and the driving shaft 21 is driven to rotate by the motor shaft. Preferably, the rotating direction of the electric motor 22 is opposite to the rotating direction of the cleaning member (for example, a roller brush), so that when the roller brush is in a rotating state, the hair can also be pulled off the roller brush by the blade assembly 30 for cleaning. Of course, when the cleaning member is in a stationary state, the rotating direction of the electric motor 22 is not limited, or when the cleaning member is in a rotating state, the rotating direction of the electric motor 22 can also be the same as the rotating direction of the cleaning member, and the present application does not limit this.

[0037] The hair cutting device 100 further comprises a rotating plate 50, which is sleeved on the driving shaft 21 to rotate synchronously with the driving shaft 21. The rotating plate 50 is provided to provide a mounting base for the blade assembly 30. In addition, the rotating plate 50 has a length extending in the axial direction of the driving shaft 21, so as to effectively protect the blade assembly 30, thereby avoiding deformation of the blade assembly 30 during pulling and cutting.

[0038] The blade assembly 30 is fixed on the rotating plate 50 and rotates synchronously with the driving shaft 21 under the driving of the driving shaft 21, so as to clean the hair wound on the roller brush during rotation, thereby realizing dynamic cleaning of the hair on the roller brush, effectively solving the problem of hair winding, and avoiding cutting the roller brush.

[0039] The blade assembly 30 has a first position and a second position. The first position is a position where the blade assembly 30 is completely accommodated in the receiving groove 13 of the housing 10, and the second position is a position where the blade assembly 30 is at least partially exposed to the receiving groove 13 and at least partially exposed to the opening 103 on the base 101.

[0040] In other words, when the blade assembly 30 is in the first position, the blade assembly 30 is fully accommodated in the accommodation groove 13 of the housing 10, i.e. in an accommodation state, at this time, the blade assembly 30 is not working, and the blade assembly 30 can be hidden in the housing 10 to make the surface of the ramp 102 of the base 101 flat and improve the appearance. When the blade assembly is in the second position, the blade assembly 30 is at least partially exposed to the accommodation groove 13 and at least partially exposed to the opening 103 on the base 101, so that the blade assembly 30 can extend out of the opening 103 to clean the hair on the cleaning member. Preferably, when the blade assembly 30 is in the second position, the first blade 31 and the second blade 32 do not deviate at the second position, i.e. at this time, the blade assembly 30 only pulls the hair off the cleaning member, without relative movement for shearing, and during the rotation of the blade assembly 30 from the second position to the first position or from the first position to the second position, relative displacement occurs in the axial direction of the drive shaft 21, so as to realize shearing of the hair. In this way, the hair on the roller brush can be dynamically cleaned, effectively solving the problem of hair entanglement, and at the same time, shearing work does not occur when the distance from the cleaning member is relatively close (second position), and during rotation, hair shearing work is performed, so that the blade assembly 30 can be effectively prevented from cutting the cleaning member, improving the user experience.

[0041] The first position and the second position have an included angle, and the included angle is less than 180°. In combination Figure 2 As shown, the housing 10 is also provided with a second limiting portion 14 for limiting the rotation angle of the blade assembly 30.

[0042] Preferably, the second limiting portion 14 is provided with two, and the two second limiting portions 14 are distributed along the axial direction of the drive shaft 21 (also the axial direction of the cleaning member). When the blade assembly 30 rotates to abut against the second limiting portion 14, the blade assembly 30 is in the second position, i.e. at the maximum rotation angle. In the present application, the motor is preferably a stepper motor, and by controlling the motor to reverse, the blade assembly 30 can return from the second position to the first position, and at the same time, the blade assembly 30 performs shearing. That is, the blade assembly 30 can shear the hair in the roller brush during the reciprocating process between the first position and the second position.

[0043] In some embodiments, the first position is a horizontal position, and the second position is a vertical position. In the first position, the blade assembly 30 is flat in the housing 10, and in the second position, the blade assembly 30 is vertically erected, and the tooth edge portion of the blade assembly 30 faces the opening.

[0044] The blade assembly 30 comprises a first blade 31 and a second blade 32. The first blade 31 is a fixed blade, which is fixedly connected with the driving shaft 21 and rotates with the driving shaft 21. The second blade 32 is a movable blade, which can reciprocate relative to the first blade 31 along the axial direction of the driving shaft 21 under the action of the guide column and the guide groove, so as to shear the hair.

[0045] Further, the tooth edge portions of the first blade 31 and the second blade 32 are sawtooth-shaped, so as to facilitate pulling the hair out of the cleaning element for shearing.

[0046] Further, the second blade 32 and the first blade 31 are provided with rotating plates 50 on both sides, i.e., the second blade 32 and the first blade 31 are clamped between the two rotating plates 50. When the driving shaft 21 drives the blade assembly 30 to rotate, i.e., the second blade 32 and the first blade 31 rotate synchronously around the driving shaft 21. Preferably, the first blade 31 and the second blade 32 rotate around the driving shaft 21 by an angle less than 180°, i.e., the motor 22 drives the first blade 31 and the second blade 32 to repeatedly switch between the first position and the second position through the driving shaft 21.

[0047] In order to enable the second blade 32 to relatively displace relative to the first blade 31 during rotation, the application provides a guide 40, which is fixedly arranged in the housing 10 and rotationally connected with the driving shaft 21.

[0048] In the embodiment, the guide 40 is arranged in the middle of the driving shaft 21, and the guide 40 is provided with a rotating hole, and the driving shaft 21 penetrates the rotating hole to penetrate the guide 40. When the driving shaft 21 rotates, the guide 40 is stationary. Of course, in other embodiments, the guide 40 can not be arranged in the middle of the driving shaft 21, or the driving shaft 21 does not penetrate the guide 40, as long as the guide 40 is arranged on the driving shaft 21 and rotationally connected with the driving shaft 21.

[0049] Since the guide 40 is arranged on the driving shaft 21, i.e., the guide 40 is equivalent to being embedded in the blade assembly 30, the blade assembly 30 is provided with a avoiding portion for avoiding the guide 40. And in the embodiment, the first blade 31 and the second blade 32 are divided into two parts by the guide 40.

[0050] In some embodiments, the guide 40 has an arc surface between the first position and the second position, and the guide groove 41 is formed on the arc surface. The guide groove 41 has a displacement distance in the axial direction of the driving shaft 21. In this way, the relative movement of the second blade 32 relative to the first blade 31 in the axial direction of the driving shaft 21 is provided.

[0051] In some embodiments, the guide groove 41 is in a spiral shape, and the guide groove 41 can just make the first blade 31 and the second blade 32 not relatively deviate at the second position, so as to avoid hurting the cleaning member. In other embodiments, the guide groove 41 can also be in a polyline shape, and the present application is not limited in this regard.

[0052] In combination with Figure 3 and Figure 4 As shown in the figures, the second blade 32 has a guide column 321 extending towards the driving shaft 21, and the guide column 321 can extend into the guide groove 41 and move along the guide groove 41. Since the guide groove 41 has a displacement distance in the axial direction of the driving shaft 21, when the second blade 32 rotates following the first blade 31, the guide column 321 moves along the guide groove 41 and generates a movement component in the horizontal direction (the axial direction of the driving shaft 21), so that the second blade 32 generates relative displacement in the horizontal direction relative to the first blade 31, that is, the second blade 32 can relatively move in the axial direction of the driving shaft 21 relative to the first blade 31, so as to form a shear between the first blade 31 and the second blade 32.

[0053] Of course, in other embodiments of the present application, the driving assembly 20 can also be provided with additional control structures for separately controlling the second blade 32 to work independently, which can be set as required and is not limited herein.

[0054] In the present embodiment, the guide column 321 is arranged on the guide strip 322 and extends from the guide strip 322 towards the guide groove 41. The guide strip 322 is clamped between the first blade 31 and the second blade 32 and is fixedly connected with the second blade 32. In this way, the relative sliding of the second blade 32 relative to the first blade 31 is ensured, which is similar to a hair clipper.

[0055] Further, since the side of the second blade 32 away from the first blade 31 is provided with a rotating plate 50, the second blade 32 is clamped between the rotating plate 50 and the guide strip 322, so that the hardness of the second blade 32 can be improved to prevent the second blade 32 from being bent or broken during the relative movement relative to the first blade 31, thereby affecting the shearing effect.

[0056] Further, the rotating plate 50 is provided with a limiting groove 51 on the side facing the guide strip 322, and the guide strip 322 is provided with a first limiting part 323 corresponding to the position of the limiting groove 51, the first limiting part 323 abuts against the groove wall 511 of the limiting groove 51 and reciprocates along the groove wall 511 to limit the movement direction of the second blade 32 relative to the first blade 31.

[0057] Further, in the axial direction of the driving shaft 21, the projection length of the limiting groove 51 is greater than the width of the guide groove 41. In this way, the relative displacement between the second blade 32 and the first blade 31 is provided with the possibility.

[0058] In order to further enhance the shearing effect between the first blade 31 and the second blade 32, the first blade 31 should be closely attached to the second blade 32. The shaving device 100 further comprises a resilient member 60 provided on the driving shaft 21, the end of the resilient member 60 abutting against the side of the second blade 32 away from the first blade 31, configured to make the second blade 32 and the first blade 31 closely arranged to improve the shearing effect.

[0059] Preferably, the resilient member 60 is provided with two groups, and each is a torsion spring. The resilient member 60 is wrapped around the driving shaft 21, and the two ends of the resilient member 60 abut against the first blade 31 and the second blade 32 respectively, and are used to press the first blade 31 and the second blade 32 tightly.

[0060] Further, when it is necessary to clean the cleaning member on the cleaning device, the shaving device 100 is rotated synchronously with the driving shaft 21 under the driving of the motor 22, from the first position to the second position, and then to the second position, the motor 22 is reversed to drive the driving shaft 21 to rotate reversely, at this time, the blade assembly 30 will pull the hair on the cleaning member when it is wrapped in the second position, and then in the process of reverse rotation, the second blade 32 can be relatively displaced along the axial direction of the driving shaft 21 relative to the first blade 31 under the action of the guide groove 41 and the guide column 321, thereby realizing the shearing of the hair. After reaching the first position, the motor 22 is reversed again to make the blade assembly 30 rotate from the first position to the second position, at this time, the second blade 32 can be relatively displaced along the axial direction of the driving shaft 21 relative to the first blade 31 under the action of the guide groove 41 and the guide column 321, and continue to shear the hair. When the cleaning is completed, the motor 22 drives the blade assembly 30 to return to the first position, thereby realizing the storage of the shaving device 100 and preventing the cleaning member from being cut.

[0061] In summary, the hair cutting device 100 of the present application, by setting the driving shaft, the blade assembly 30 follows the driving shaft to rotate, to pull out the hair wound on the cleaning piece, by setting the guide column and the guide groove, and the guide groove has a displacement distance in the axial direction of the driving shaft, so that the second blade can relatively displace in the axial direction of the driving shaft relative to the first blade in the process of rotation, to realize shearing hair in the process of rotation, while avoiding cutting the rolling brush, improving the user experience.

[0062] The above examples are only used to illustrate the technical solutions of the present application and not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application.
