Description

Technical Field

[0001] The utility model relates to a carding device which is convenient to operate. Background Art

[0002] When a user uses a carding device such as a comb to card hair, the teeth of the comb will entangle the hair dropped by the user. The hair entangled on the teeth of the comb will affect the use of the comb. Therefore, some existing combs are provided with a panel assembly and a button unit for driving the movement of the panel assembly. The panel assembly can be sleeved on the teeth of the comb. When the button unit is pressed by the user, the button unit will drive the panel assembly to move. The panel assembly will move relative to the teeth of the comb and push the hair entangled on the teeth of the comb to separate from the teeth of the comb.

[0003] The overall length direction of the multiple teeth of the existing comb is the same as or close to the extension direction of the handle. The panel assembly is correspondingly arranged with the length direction the same as or close to the extension direction of the handle. In order to make the driving force generated by the button unit be evenly applied to the panel assembly, the button unit is generally arranged in the middle of the panel assembly. However, the length of the panel assembly is relatively long, which will make the button unit located in the middle of the panel assembly have a relatively long distance from the handle on one side of the panel assembly, resulting in that the user cannot or is relatively difficult to press the button unit with a relatively long distance from the handle after holding the handle with one hand, affecting the user experience.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0038] As Figure 1 and Figure 2 shown, corresponding to a carding device with convenient operation according to a preferred embodiment of the present utility model, it includes a housing 1, a handle joint 2, a panel assembly 3, a button 4 and a hinge member 5; it may also include a push plate 6. Among them, the carding device can specifically be a comb.

[0039] The handle joint 2 is connected to the housing 1, and after the handle joint 2 is connected to the handle ( Figure 9 shown), it can be held by the user. Among them, the handle joint 2 can be fixedly connected to the housing 1, and the handle joint 2 is detachably connected to the handle, so as to facilitate the user to replace different - function joints, and then drive the housing 1 to meet the user's usage requirements. The handle joint 2 can specifically be fixedly connected to the housing 1 through fasteners such as screws and pins.

[0040] Further referring to Figure 3 and Figure 6The housing 1 includes a main body shell 11, a button cover 12 and a tooth comb bottom plate 13. Both ends of the main body shell 11 are open, for example, the main body shell 11 is provided with openings at two opposite ends along the thickness direction thereof, and the main body shell 11 can be connected to the handle joint 2. Specifically, the main body shell 11 is roughly rectangular, which conforms to the usage habits of most users for the shape of the comb, and the handle joint 2 is connected to one end of the main body shell 11 in the length direction.

[0041] The button cover 12 can be covered on an opening of the main housing 11. The button cover 12 is provided with a through hole 121. The through hole 121 can be adapted to the end surface of the button 4 for the user to press, so that the pressing end surface of the button 4 can be exposed to the outside through the through hole 121, thereby facilitating the user to press the button 4. The tooth comb bottom plate 13 can be covered on another opening of the main housing 11. The tooth comb bottom plate 13 is provided with a plurality of mounting holes, each of which can be used to mount a comb tooth; for example, the mounting hole and one end of the comb tooth are interference fit, so that one end of the comb tooth is fixedly connected to the tooth comb bottom plate 13; the main body of the comb tooth is arranged on the side of the tooth comb bottom plate 13 away from the main housing 11, so that the main body of the comb tooth is exposed to the outside.

[0042] The main housing 11 is also provided with an air flow channel, and the comb bottom plate 13 is also provided with an air outlet. The air flow from the handle enters the air flow of the main housing 11 from the handle joint 2, flows out from the air outlet of the comb bottom plate 13 after passing through the air flow channel, reaches the surface of the user's hair, and has the effect of blowing and caressing the hair.

[0043] The panel assembly 3 is arranged on the side of the tooth comb base plate 13 away from the main body shell 11. The panel assembly 3 is provided with comb holes corresponding to the comb teeth, for example, the comb holes are slightly larger than the comb teeth. When the panel assembly 3 moves relative to the comb teeth, the wall forming the comb holes will contact the hair attached to the comb teeth, and will be pushed out as the panel assembly 3 moves. The hair on the comb teeth will be driven by the panel assembly 3 and pushed, thereby removing the hair on the comb teeth. In addition, the panel assembly 3 is also provided with a through opening corresponding to the air outlet of the tooth comb base plate 13 for air flow outflow. Among them, the panel assembly 3 can specifically include a panel 33 and a panel cover 34, and the panel cover 34 can be covered on the side of the panel 33 away from the tooth comb base plate 13.

[0044] The button 4 is arranged at one end of the housing 1 in the length direction near the handle joint 2, and the end surface of the button 4 for the user to press is exposed to the outside through the through hole 121 of the button cover 12. After the user holds the handle, since the button 4 is arranged at one end of the housing 1 near the handle joint 2, that is, the button 4 is near the handle joint 2, the user can press the button 4 with one hand after holding the handle, which is convenient to operate and improves the user's experience.

[0045] Among them, when the button 4 is pressed by the user, it can cooperate with the hinge member 5 to drive the panel assembly 3 (to be described later). To facilitate the cooperation between the button 4 and the hinge member 5, one end of the button 4 facing the hinge member 5 is formed with a pressing portion 41 protruding towards the hinge member 5, and the pressing portion 41 is used to cooperate with the hinge member 5. For example, the pressing portion 41 is used to abut against the hinge member 5.

[0046] Further referring to Figure 7 , the hinge member 5 may include a body portion 54, and a hinge portion 51, an abutting portion 52 and a driving portion 53 connected to the body portion 54. For example, the body portion 54, the hinge portion 51, the abutting portion 52 and the driving portion 53 are of an integral structure. The hinge portion 51 can be hinged to the housing 1 to achieve the rotational connection between the hinge member 5 and the housing 1. For example, the hinge portion 51 is a rotating shaft protruding from the body portion 54, and the housing 1 is provided with a rotating hole cooperating with the rotating shaft. The rotating shaft is inserted into the rotating hole of the housing 1 to achieve the rotational connection between the hinge member 5 and the housing 1. At this time, the hinge member 5 can form a lever structure, and the rotating shaft forms the fulcrum of the lever structure. Among them, two hinge portions 51 can be provided, and the two hinge portions 51 are arranged on opposite sides of the body portion 54. Both of the two hinge portions 51 can be rotating shafts, and the housing 1 is correspondingly provided with rotating holes located on both sides of the body portion 54. Each rotating shaft cooperates with a rotating hole to make the relative rotation between the hinge member 5 and the housing 1 more stable. Specifically, the hinge portion 51 can be provided at the end of the body portion 54. For example, the hinge portion 51 is provided at one end of the body portion 54 close to the handle joint 2.

[0047] The abutting portion 52 can be formed by protruding towards the button 4 at one end of the hinge member 5 facing the button 4. Specifically, the abutting portion 52 is formed by protruding towards the button 4 at one end of the body portion 54 facing the button 4. The abutting portion 52 can abut against the pressing portion 41 of the button 4. When the button 4 is pressed, the pressing portion 41 of the button 4 will abut against the abutting portion 52 and apply a pressing force to the abutting portion 52 to drive the abutting portion 52, and make the abutting portion 52 form the force-receiving end of the lever structure, thereby driving the hinge member 5 to rotate around the hinge portion 51. Among them, two abutting portions 52 can be provided, and the two abutting portions 52 are arranged on opposite sides of the hinge member 5, specifically on opposite sides of the body portion 54. Correspondingly, preferably two pressing portions 41 are provided, and the two pressing portions 41 are arranged on opposite sides of the button 4. Each abutting portion 52 is used to correspondingly abut against one pressing portion 41, so that when the pressing portion 41 abuts against the hinge member 5 and applies a pressing force to opposite sides of the hinge member 5, the pressing force can act on the hinge member 5 evenly.

[0048] The driving part 53 can serve as the force - applying end of the lever structure formed by the hinge 5, and the driving part 53 can be used to drive the panel assembly 3 to move. Specifically, when the button 4 abuts against the abutting part 52 of the hinge 5 and applies a pressing force to the abutting part 52, the driving part 53 of the button 4 will rotate around the hinge part 51. For example, the driving part 53 rotates towards the panel assembly 3 to drive the panel assembly 3 to move. Among them, the driving part 53 can apply a driving force to the middle position of the panel assembly 3 to improve the smoothness of the movement of the panel assembly 3.

[0049] Compared with the situation where the button is set in the middle of the panel assembly 3, which is inconvenient for users to operate (when the user holds the handle, the finger for pressing, generally the thumb, is far from the button, making it inconvenient to apply force for pressing. Therefore, two hands need to be used in cooperation, the operation is cumbersome, and the experience is poor), the present utility model sets the hinge 5 to form a lever structure. By pressing the button 4 that is not in the middle of the panel assembly 3 (but near the handle 2) to apply pressure, the lever structure will cause a movement at another position (the driving part 53) of the lever structure, and then apply pressure to the middle of the panel assembly 3. Therefore, the user can apply a pressing force to the position near the handle joint 2 with one hand while holding the handle to press the button 4, and apply pressure to the middle position of the panel assembly 3 through the hinge 5 to drive the panel assembly 3 to move smoothly.

[0050] In some specific embodiments, the driving part 53 and the hinged part 51 are arranged at opposite ends of the abutting part 52. For example, the hinged part 51 and the driving part 53 are arranged at two ends of the body part 54. Specifically, the abutting part 52 is arranged at the middle position of the body part 54, the hinged part 51 is arranged at one end of the body part 54 close to the handle joint 2, and the driving part 53 is arranged at the end of the body part 54 away from the hinged part 51. Therefore, the distance from the driving part 53 to the hinged part 51 is more than the distance from the abutting part 52 to the hinged part 51, and the moment at the driving part 53 is larger. At this time, the lever structure formed by the hinge 5 is a form of a laborious lever. Since the driving part 53 is farther from the hinge than the abutting part 52, when the hinge 5 rotates by a certain angle around the hinged part 51, the rotation path of the driving part 53 is more than that of the abutting part 52. Therefore, the abutting part 52 is driven by the button 4 to move a smaller displacement, and the driving part 53 can achieve a larger displacement. The moving amount of the abutting part 52 is proportional to the moving amount when the button 4 is pressed, and the moving amount of the driving part 53 is proportional to the moving distance of the panel assembly 3. That is, a small moving amount when the button 4 is pressed can drive the panel assembly 3 to move a longer distance. Specifically, after the button 4 moves one unit distance along the pressing direction, the abutting part 52 of the hinge 5 is pressed by the button 4 and moves one unit distance along the pressing direction of the button 4, while the driving part 53 moves 1.6 - 5 unit distances along the pressing direction of the button 4. At this time, the panel assembly 3 is driven by the driving part 53 to move 1.6 - 5 unit distances along the pressing direction of the button 4, that is, the distance that the panel assembly 3 moves along the pressing direction of the button 4 is 1.6 - 5 times the distance that the button 4 moves along its pressing direction.

[0051] In the existing comb, the moving distance of the panel assembly 3 is the same as or close to the distance that the button 4 is pressed. The maximum displacement when the button 4 is pressed is generally about 4 mm, and the maximum displacement of the panel assembly 3 in the existing comb is also about 4 mm. The maximum displacement of about 4 mm of the panel assembly 3 reduces the cleaning effect on the hair attached to the comb teeth. In this application, by forming a laborious lever structure with the hinge 5, a smaller amount of pressing of the button 4 can make the panel assembly 3 move a longer distance, so as to improve the cleaning effect of the panel assembly 3 on the hair attached to the comb teeth. Specifically, the maximum displacement of the panel assembly 3 along the pressing direction of the button 4 is 1.6 - 5 times the maximum displacement of the button 4 along the pressing direction of the button 4 when the button 4 is pressed. Specifically, the maximum displacement of the button 4 along the pressing direction of the button 4 when the button 4 is pressed can be 2 - 6 mm, preferably 4 mm, and the maximum displacement of the panel assembly 3 along the pressing direction of the button 4 can be 6 - 14 mm, preferably 10 mm.

[0052] The push plate 6 can be fixedly connected to the panel assembly 3, and the push plate 6 is connected or abutted against the driving part 53 of the hinge member 5, so that the driving force of the driving part 53 of the hinge member 5 can be applied to the push plate 6, and then act on the panel assembly 3 fixedly connected to the push plate 6, that is, the driving part 53 can drive the push plate 6 to make the panel assembly 3 move synchronously.

[0053] Further referring to Figure 8 , for facilitating the application of force from the driving part 53 to the push plate 6, the push plate 6 is provided with a groove 61. For example, the surface at one end of the push plate 6 facing the hinge member 5 is recessed to form the groove 61. The groove 61 can be used to accommodate the driving part 53 of the hinge member 5. Among them, the groove 61 is located at the middle position of the push plate 6. Specifically, the groove 61 can be provided at the central position of the push plate 6, and the central position of the push plate 6 can coincide with the central position of the panel assembly 3. Therefore, the acting force applied by the driving part 53 can act on the central position of the panel assembly 3 through the push plate 6, realizing the application of a balanced driving force to the panel assembly 3, so that the panel assembly 3 moves smoothly.

[0054] In some specific embodiments, to achieve the fixed connection between the push plate 6 and the panel assembly 3, the end of the push plate 6 facing the panel assembly 3 is provided with fixing holes 62. The fixing holes 62 are symmetrically located on both sides of the groove 61. The end of the panel assembly 3 facing the push plate 6 is provided with fixing posts 31. The fixing posts 31 of the panel assembly 3 can form an interference fit with the fixing holes 62 to achieve the fixed connection between the push plate 6 and the panel assembly 3. Among them, two fixing posts 31 and two fixing holes 62 can be respectively provided. Each fixing post 31 and a fixing hole 62 form an interference fit. The two fixing posts 31 can be symmetrically arranged relative to the central position of the push plate 6, that is, relative to the groove 61. The two fixing holes 62 are symmetrically distributed relative to the central position of the panel assembly 3 respectively to increase the stability during movement. It should be noted that in other embodiments, the fixing holes 62 can also be provided on the panel assembly 3, and the fixing posts 31 can be provided on the push plate 6. In addition, the push plate 6 and the panel assembly 3 can also be fixedly connected by fixing parts such as screws or buckles, which are not limited herein.

[0055] Further referring to Figure 3 and Figure 6 , in some specific embodiments, to enable the panel assembly 3 and the button 4 to automatically reset when the button 4 is released later, the carding device can also be provided with an elastic member 32. The elastic member 32 is sleeved on the fixing post 31, and one end of the elastic member 32 abuts against the push plate 6, and the other end of the elastic member 32 abuts against the housing 1. For example, the other end of the elastic member 32 abuts against the main body housing 11 or the comb base plate 13. Further referring to Figure 4 and Figure 5, when the button 4 is pressed, the push plate 6 will move relative to the housing 1 from the initial position. Specifically, the push plate 6 moves towards the panel assembly 3, and the fixed column 31 is provided at one end of the panel assembly 3 facing the push plate 6. When the push plate 6 moves towards the panel assembly 3, the push plate 6 will squeeze the elastic member 32 and drive the panel assembly 3 to extend. Further refer to Figure 1 and Figure 2 , when the button 4 is released, the elastic member 32 is elastically reset by itself to drive the push plate 6 to move to the initial position. When the push plate 6 is reset, it will drive the hinge member 5 and the button 4 in contact with the hinge member 5 to move, thereby driving the button 4 and the hinge member 5 to reset. Among them, when there are two fixed columns 31, there can also be two elastic members 32, and each elastic member 32 is sleeved on one fixed column 31. The elastic member 32 can specifically be a spring.

[0056] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
