Description

Technical Field

[0001] The invention relates to a pet grooming tool, in particular to a pet comb for removing shed or tangled hair from the fur of a pet. Background Art

[0002] With the improvement of living standards, people's demand for pets has gradually increased, and pets have become a part of our lives.

[0003] The fur of pets may have hair that is shed on the skin, that is, hair that is not attached to the skin. Currently, there are grooming tools on the market that are specifically used to clean the shed hair or comb the hair of pets. The grooming tool has a comb on the head, and the comb has a row of teeth. However, the hair of pets often gets tangled, and the above-mentioned traditional pet combs will be stuck by the tangled hair when combing the pet's hair.

[0004] In order to solve the above technical problem, the patent document of US Patent No. US7077076B2 in Document 1 discloses a pet grooming tool, which discloses a comb with a blade, the front end of the comb is comb teeth, and the roots of the comb teeth have blades for cutting tangled hair. When combing the pet's hair, the blade can cut off the tangled hair, so that the pet's hair can be combed with the comb teeth.

[0005] Document 2, with publication number CN108990827A, discloses a pet comb and hair removal mechanism, which discloses a hair removal part, which includes a pushing portion that can move between the root of the comb teeth and the front end of the comb teeth, the pushing portion includes a back pushing portion that can remove hair on the back of the strip-shaped comb teeth and a gap pushing portion that can remove hair in the gaps between the comb teeth, and tooth gaps for the strip-shaped comb teeth to pass through are provided between the gap pushing portions on the pushing portion.

[0006] The button is connected to the push plate and the push part through a rotating part, and the push plate can be controlled to move up and down by sliding the button forward and backward. Due to the movable connection between the rotating part, the button and the push plate, there is a certain gap between the rotating part and the button or the push plate; when the user uses the comb, the force applied by the finger on the button is transmitted to the hair removal push part, and there is a delay caused by the above gap; in addition, the hair removal push plate of the conventional comb is reset by a spring, and the thrust will gradually increase when the hair removal push plate is pushed. After long-term use, the fingers are prone to fatigue, which reduces the user experience. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a pet hair removal comb, in which a hair removal push plate is sensitively responsive when a button is pushed and relatively labor-saving when started, so as to improve the user's hair combing experience.

[0008] The technical solution adopted by the present invention to solve the above technical problems is: a pet hair removal comb, characterized by comprising a comb head with a knife holder assembly installed, a handle assembly and a hair removal push plate; the comb head is installed at the front end of the handle assembly, and the hair removal push plate is installed on the comb head and located at the rear side of the knife holder assembly;

[0009] The handle assembly is provided with a button assembly that can slide forward and backward, and the hair removal push plate includes a push plate that can move up and down and a push portion at the front end of the push plate;

[0010] A connecting rod is provided between the button assembly and the back of the push plate, and the two ends of the connecting rod are movably connected to the button assembly and the push plate respectively, and the sliding of the button assembly pushes the movement of the push plate through the connecting rod;

[0011] A force arm is provided on the connecting rod, and a force-bearing arc surface is provided on the back of the hair removal push plate. The front end of the force arm is pressed tightly on the force-bearing arc surface. When the button assembly slides back and forth, the front end of the force arm can slide in close contact on the force-bearing arc surface.

[0012] A further preferred solution of the present invention is that the front end of the force-applying arm is a first cylinder, and the first cylinder is tightly pressed against the force-bearing arc surface.

[0013] A further preferred embodiment of the present invention is as follows: the connecting rod comprises two connecting arms and a rear arm, the force arm is located in the middle of the two connecting arms, the front end of the connecting arm is a second cylinder, the rear end of the rear arm is a third cylinder, the second cylinder is inserted into the shaft connection hole of the shaft connection seat provided on the back of the push plate, and the third cylinder is clamped in the clamping slot of the button assembly.

[0014] A further preferred solution of the present invention is: the button assembly comprises a button which can slide on the surface of the handle assembly and a connecting locking block, the button is engaged with the connecting locking block, and the slot is provided on the connecting locking block.

[0015] A further preferred embodiment of the present invention is that the front end of the force applying arm is located above the front end of the connecting rod, and the line between the center of the first cylinder and the center of the third cylinder and the line between the center of the second cylinder and the third cylinder form an angle A.

[0016] A further preferred solution of the present invention is that the force-bearing arc surface and the second cylinder have the same center.

[0018] A further preferred embodiment of the present invention is as follows: the tool holder assembly comprises a plate-like base and a row of strip-like comb teeth made of metal at the front end of the plate-like base.

[0019] A further preferred embodiment of the present invention is that the pushing portion includes a gap pushing portion capable of removing hair from the gaps between the comb teeth.

[0020] A further preferred solution of the present invention is: the shell includes a bottom shell and a head cover connected to the handle assembly, and the bottom shell and the head cover are fixed by fasteners.

[0021] Compared with the prior art, the advantage of the present invention is that a force arm is provided on the connecting rod between the button assembly and the push plate, and the front end of the force arm is pressed tightly against the force-bearing arc surface of the push plate. When the button assembly slides back and forth, the front end of the force arm can slide in close contact on the force-bearing arc surface, so that the action on the button assembly can be transmitted to the hair removal push plate without delay, and respond instantly, so as to improve the user experience of the pet hair removal comb.

[0022] Since the force arm bears part of the force exerted by the connecting rod on the push plate, the button assembly can save more effort when driving the push plate through the connecting rod; especially when the button assembly is in the starting position, the effort-saving effect is more obvious; as the inclination of the connecting rod and the force arm increases, the effort-saving effect is relatively less.

[0033] The present invention is further described in detail below with reference to the accompanying drawings.

[0034] A pet comb is a pet hair grooming tool that can be used to comb a pet's hair, cut tangled pet hair, or thin out overly dense pet hair.

[0035] like Figures 1 to 3 As shown, it is a structural schematic diagram of the pet hair removal comb 100 in this embodiment. The pet hair removal comb 100 includes a comb head 10 with a blade holder assembly 30 installed, a handle assembly 20 and a hair removal push plate 40; the comb head 10 is installed at the front end of the handle assembly 20, and the hair removal push plate 40 is installed on the comb head 10 and is located at the rear side of the blade holder assembly 30.

[0036] A button assembly 50 is provided on the handle assembly 20 and can slide forward and backward. Figure 7 As shown, the hair removal push plate 40 includes a push plate 41 that can move up and down and a push portion 42 at the front end of the push plate 41.

[0037] A connecting rod 60 is provided between the button assembly 50 and the back of the push plate 41 , and both ends of the connecting rod 60 are movably connected to the button assembly 50 and the push plate 41 , respectively. The sliding of the button assembly 50 pushes the push plate 41 to move through the connecting rod 60 .

[0038] like Figure 2 and Figure 3 As shown, a force arm 61 is provided on the connecting rod 60, and a force-bearing arc surface 43 is provided on the back of the hair removal push plate 40. The front end of the force arm 61 is tightly pressed against the force-bearing arc surface 43. When the button assembly 50 slides back and forth, the front end of the force arm 61 can slide in close contact on the force-bearing arc surface 43.

[0039] A force arm 61 is provided on the connecting rod 60 between the button assembly 50 and the push plate 41, and the front end of the force arm 61 is pressed tightly against the force-bearing arc surface 43 of the push plate 40. When the button assembly 50 slides back and forth, the front end of the force arm 61 can slide in close contact on the force-bearing arc surface 43, so that the action on the button assembly 50 can be transmitted to the hair removal push plate 40 without delay, and respond instantly to improve the user experience of the pet hair removal comb.

[0040] Since the force arm 61 bears part of the force exerted by the connecting rod 60 on the push plate 40, the button assembly 50 can save more effort in the process of driving the push plate through the connecting rod 60; especially when the button assembly 50 is in the starting position, the effort-saving effect is more obvious; as the inclination degree of the connecting rod 60 and the force arm 61 increases, the effort-saving effect is relatively less.

[0041] Specifically, Figure 2 , Figure 3 and Figures 8 to 10 As shown, the front end of the force arm 61 is a first cylinder a1, and the first cylinder 1 is pressed tightly against the force arc surface 43. A boss b is provided on the back of the push plate 41, and the force arc surface 43 is provided on the boss b. Specifically, the boss b is located at the center of the two shaft seats c, and the height of the boss b is greater than the height of the shaft seats c, so that the first cylinder a1 on the force arm 61 is further back than the second cylinder a2 on the connecting arm 62, that is, the force arm 61 is shorter than the connecting arm 62.

[0042] The connecting rod 60 includes two connecting arms 62 and a rear arm 63. The force arm 61 is located in the middle position of the two connecting arms 62. The front end of the connecting arm 62 is a second cylinder a2, and the rear end of the rear arm 63 is a third cylinder a3. The second cylinder a2 is inserted into the shaft connection hole c1 of the shaft connection seat c on the back side of the push plate 41, and the third cylinder a3 is clamped in the clamping slot 52 of the button assembly 50.

[0043] The force arm 61 is integrally formed with the connecting rod 60, and the second cylinder a2 on the connecting arm 62 is located in the shaft connection hole c1; when the button assembly 50 pushes the connecting rod 60, the second cylinder a2 will rotate relative to the shaft connection seat c, and therefore the second cylinder a2 needs to have a certain amount of clearance movement in the shaft connection hole c1, and this clearance movement is exactly the delayed response of the button assembly 50 when pushing the push plate 41, and is the core element of the first cylinder a1 on the force arm 61 of the present invention in close contact with the force-bearing arc surface 43, which enables the button assembly 50 to push the push plate 41 without gap through the force arm 61, thereby improving the user experience of the comb responding promptly when the button assembly 50 controls the hair removal push plate 40.

[0044] like Figure 2 , Figure 3 and Fig. 9 , Fig.10 As shown, the button assembly 50 includes a button 51 that can slide on the surface of the handle assembly 20 and a connecting lock block 53 . The button 51 is engaged with the connecting lock block 53 , and a slot 52 is provided on the connecting lock block 53 .

[0045] The third cylinder a3 on the rear arm 63 is clamped in the clamping slot 52 of the connecting lock block 53 . When the button assembly 50 is pushed, the connecting rod 60 will change its angle, and the third cylinder a3 can rotate relative to the clamping slot 52 of the connecting lock block 53 .

[0046] like Fig.10 As shown, the front end of the force-applying arm 61 is located above the front end of the connecting rod 60, and the line between the center of the first cylinder a1 and the center of the third cylinder a3 and the line between the center of the second cylinder a2 and the third cylinder a3 form an angle A. The angle between the line between the center of the first cylinder a1 and the center of the third cylinder a3 and the longitudinal moving trajectory of the push plate 41 is B. When the push plate 41 moves downward to push out the hair, the angle B gradually decreases. The force-bearing arc surface 43 and the second cylinder a2 have the same center. With the above-mentioned structure, the first cylinder a1 at the front end of the force-applying arm 61 can always be in contact with the force-bearing arc surface 43, and when the push plate 41 and the connecting arm 62 are displaced, the force-applying arm 61 will not interfere with the connecting arm 62.

[0047] It should also be noted that as the button 51 on the button assembly 50 moves at a constant speed from the starting point to the end point, the moving speed of the push plate 41 gradually decreases; as the angle B gradually decreases, the component force applied to the push plate by the force arm 61 gradually increases, which will make the pushing force required for the button 51 at the starting point slightly larger, and the pushing force required when approaching the end point slightly smaller.

[0048] During the movement of the connecting rod 60, the first cylinder a1 on the force-applying arm 61 contacts the force-bearing arc surface 43 on the hair removal push plate 40 and applies a thrust on the force-bearing arc surface 43; and the second cylinder a2, as a fixed position, does not directly participate in the action of pushing the push plate 41. When the push plate 41 moves downward, the third cylinder a3 rotates in the slot 52. As the angle B gradually decreases, the thrust required to be applied to the button 51 gradually decreases.

[0049] On the other hand, as the push plate 41 moves downward, the rebound force applied by the return spring 80 on the push plate 41 gradually increases, thereby reconciling the gradual decrease in the force of the force arm 61 in the above analysis. Ultimately, the force applied by the user when pushing the button 51 remains basically consistent, further improving the thrust stability of the user when operating the button, thereby improving the comfort of the user pushing the button.

[0050] The comb head 10 includes a housing 11, and two return springs 80 are arranged between the housing 61 and the push plate 41. When the force applied to the button assembly 50 by the user is removed, the push plate 41 will return to the initial position under the action of the return springs 80.

[0051] Preferably, if Figure 6 As shown, the tool holder assembly 30 in this embodiment includes a plate-shaped base 31 and a row of strip-shaped comb teeth 32 made of metal at the front end of the plate-shaped base 31 .

[0052] like Figure 7As shown, the push portion 42 includes a gap push portion p that can remove the hair in the comb teeth gap. The push portion 42 moves downward to remove the pet hair stuck in the middle of the strip-shaped comb teeth 32.

[0053] The housing 11 includes a bottom shell k2 and a head cover k1 connected to the handle assembly 20 , and the bottom shell k2 and the head cover k1 are fixed by fasteners.

[0054] The pet hair removal comb provided by the present invention is introduced in detail above. The principle and implementation mode of the present invention are described in detail using specific examples herein. The description of the above embodiments is only used to help understand the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, the present invention can also be improved and modified in a number of ways without departing from the principle of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
