Description

Technical Field

[0001] The present disclosure relates to pet grooming tools, and particularly to a pet comb for removing fallen or tangled pet hair.

Background Art

[0002] With the improvement of living standards, more and more people are raising pets, and pets have become a part of people's lives.

[0003] Pets often shed hair. Specialized grooming tools are available on the market to remove the fallen hair of pets or to comb the pet's hair neatly. The grooming tool has a comb at the top, and the comb has teeth arranged side by side. However, pet hair is often tangled, and conventional pet combs become immobile in the tangled hair when combing the pet's hair.

[0004] To solve the above technical problems, the pet grooming tool described in Patent Document 1 has a comb with a blade tip. The tip of this comb is provided with teeth, and a blade tip for cutting tangled hair is provided at the root part of the teeth. When this tool is used for pet grooming, the blade tip cuts the tangled hair, so that the teeth can smoothly comb the pet's hair.

[0005] Patent Document 2 discloses a pet comb and a hair removal mechanism. According to Patent Document 2, a hair removal part including an extrusion part movable between the root part and the tip of the teeth is provided. The extrusion part has a rear extrusion part for removing hair from the rear side of the strip-shaped teeth and a gap extrusion part for removing hair from the gaps between the teeth. A tooth gap is provided between the gap extrusion parts of the extrusion part, and the strip-shaped teeth can pass through it.

[0006] [Patent Document 1] U.S. Patent No. 7077076 [Patent Document 2] Chinese Patent Application Publication No. 108990827 Specification [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] The button is connected to the extrusion plate and extrusion mechanism via a rotating member, and the extrusion plate can be controlled to move up and down by sliding the button back and forth. Because the rotating member is movably connected to the button and the extrusion plate, a certain gap exists between the rotating member and the button or extrusion plate. When the user operates the comb, the force applied by the finger on the button is transmitted to the hair removal extrusion mechanism, but there is a delay due to the gap. In addition, the hair removal extrusion plate of conventional combs returns to its original position due to a spring. When the hair removal extrusion plate is pressed, the pushing force gradually increases, and with prolonged use, the finger can easily become fatigued, making it inconvenient for the user.

[0008] This disclosure aims to solve the aforementioned technical problems and provides a pet hair removal comb that pushes a hair removal extrusion plate via a button, which features a highly sensitive response and easy starting, thereby improving user convenience in hair grooming. [Means for solving the problem]

[0009] To solve the above technical problems, this disclosure employs the following technical solution. The pet hair removal comb includes a comb head to which a blade holder is attached, a handle, and a hair removal extrusion plate, the comb head being attached to the tip of the handle. The hair removal extrusion plate is attached to the comb head and is located behind the blade holder.

[0010] The handle portion is provided with a button portion that can slide in the front-to-back direction. The hair removal extrusion plate includes an extrusion plate that can move in the vertical direction and an extrusion portion provided at the tip of the extrusion plate.

[0011] A connecting rod is provided between the button portion and the back surface of the extrusion plate. Both ends of the connecting rod are movably connected to the button portion and the extrusion plate, respectively. The button portion is configured to slide and move by pushing the extrusion plate via the connecting rod.

[0012] The connecting rod is installed together with the force-applying arm. An arc-shaped force-bearing surface is provided on the back of the hair-removing extrusion plate. The tip of the force-applying arm is firmly pressed against the arc-shaped force-bearing surface. When the button slides back and forth, the tip of the force-applying arm can slide while in close contact with the arc-shaped force-bearing surface.

[0013] In a more preferred embodiment of the present disclosure, a first cylinder may be provided at the tip of the load-bearing arm. The first cylinder may be pressed firmly against the arc-shaped force-bearing surface.

[0014] In a more preferred embodiment of the present disclosure, the coupling rod may include two coupling arms and a rear arm. The load-bearing arm may be located in the center between the two coupling arms, and a second cylinder may be provided at the end of each coupling arm, and a third cylinder may be provided at the rear end of the rear arm. The second cylinder passes through a coupling hole in a coupling socket provided on the back of the extrusion plate, and the third cylinder can be engaged with a groove in the button portion.

[0015] In a more preferred embodiment of the present disclosure, the button portion may include a button slidable on the surface of the handle portion and a coupling locking member. The button may be coupled to the coupling locking member, and a groove may be provided in the coupling locking member.

[0016] In a more preferred embodiment of the present disclosure, the tip of the load-applying arm may be located above the tip of the connecting rod. The line connecting the center point of the first cylinder and the center point of the third cylinder, and the line connecting the center point of the second cylinder and the center point of the third cylinder, form an angle A.

[0017] In a more preferred embodiment of the present disclosure, the arcuate force-bearing surface and the second cylinder have the same center.

[0018] In a more preferred embodiment of the present disclosure, the comb head may include an outer shell, and two return springs may be positioned between the outer shell and the extrusion plate.

[0019] In a more preferred embodiment of the present disclosure, the blade holder portion may include a plate-shaped base and a strip-shaped row of metal comb teeth provided at the tip of the plate-shaped base.

[0020] In a more preferred embodiment of this disclosure, the extruder may include a gap extruder for removing hair from the gaps between the comb teeth.

[0021] In a more preferred embodiment of the present disclosure, the outer shell may include a bottom outer shell coupled to the handle portion and a head cover, the bottom outer shell and the head cover may be fastened together with fasteners. [Effects of the Invention]

[0022] Compared to conventional technology, this disclosure offers the following advantages: A force-applying arm is provided on the connecting rod between the button portion and the extrusion plate, and the tip of the force-applying arm is firmly pressed against the arc-shaped force-bearing surface of the extrusion plate. As the button portion slides back and forth, the tip of the force-applying arm can slide in close contact with the arc-shaped force-bearing surface, so that the force applied to the button portion is transmitted to the hair-removing extrusion plate without delay. Therefore, this disclosure can provide a timely response and improve the user's ease of use of the pet hair-removing comb.

[0023] Since the boosting arm partially bears the force of the connecting rod on the extrusion plate, it can save effort in the process of moving the extrusion plate through the connecting rod by the button part. In particular, when the button part is at the starting position, the effort-saving effect becomes prominent. When the inclination of the connecting rod and the boosting arm increases, the effort-saving effect decreases.

[Figure 5] It is an exploded view of a pet hair comb. [Figure 6] It is a diagram showing the overall configuration of the blade holder part. [Figure 7] It is a diagram showing the overall configuration of the hair removal extrusion plate. [Figure 8] It is a diagram showing the overall configuration of the connecting rod. <000011​​​​​​​​​​​​​​​​​​​Figures 1-3 show a pet hair removal comb 100 according to an embodiment of the present disclosure. The pet hair removal comb 100 comprises a comb head 10 to which a blade holder portion 30 is attached, a handle portion 20, and a hair removal extrusion plate 40. The comb head 10 is attached to the tip of the handle portion 20. The hair removal extrusion plate 40 is attached to the comb head 10 and is located behind the blade holder portion 30.

[0028] The handle portion 20 is equipped with a button portion 50 that is slidable in the front-to-back direction. As shown in Figure 7, the hair removal extrusion plate 40 includes an extrusion plate 41 that is movable in the vertical direction and an extrusion portion 42 provided at the tip of the extrusion plate 41.

[0029] A connecting rod 60 is provided between the button portion 50 and the back surface of the extrusion plate 41. Both ends of the connecting rod 60 are movably connected to the button portion 50 and the extrusion plate 41, respectively. The button portion 50 slides, pushing and moving the extrusion plate 41 via the connecting rod 60.

[0030] As shown in Figures 2 and 3, the connecting rod 60 is positioned together with the force-bearing arm 61. An arc-shaped force-bearing surface 43 is provided on the back of the hair-removing extrusion plate 40. The tip of the force-bearing arm 61 is pressed firmly against the arc-shaped force-bearing surface 43. When the button portion 50 slides back and forth, the tip of the force-bearing arm 61 can slide while in close contact with the arc-shaped force-bearing surface 43.

[0031] The connecting rod 60 is positioned between the button portion 50 and the extrusion plate 41 together with the force-applying arm 61, and the tip of the force-applying arm 61 is firmly pressed against the arc-shaped force-bearing surface 43 of the extrusion plate 41. When the button portion 50 slides back and forth, the tip of the force-applying arm 61 slides in close contact with the arc-shaped force-bearing surface 43, so that the movement of the button portion 50 is transmitted to the hair-removing extrusion plate 40 without delay. Therefore, this disclosure can provide a timely response and improve the user experience of the pet hair-removing comb.

[0032] The force-applying arm 61 partially bears the force of the connecting rod 60 to the extrusion plate 41, thus reducing the effort required to move the extrusion plate via the connecting rod 60 using the button portion 50. The effort-saving effect is particularly pronounced when the button portion 50 is in the starting position. The effort-saving effect decreases as the inclination between the connecting rod 60 and the force-applying arm 61 increases.

[0033] Specifically, as shown in Figures 2, 3, and 8-10, a first cylinder a1 is provided at the tip of the load-bearing arm 61. The first cylinder a1 is strongly pressed against the arc-shaped force-bearing surface 43. A boss b is provided on the back of the extrusion plate 41. The arc-shaped force-bearing surface 43 is provided on the boss b. Specifically, the boss b is located in the center between the two coupling sockets c. By making the height of the boss b greater than the height of the coupling sockets c, the first cylinder a1 provided on the load-bearing arm 61 is positioned behind the second cylinder a2 provided on the coupling arm 62. In other words, the load-bearing arm 61 is shorter than the coupling arm 62.

[0034] The coupling rod 60 includes two coupling arms 62 and a rear arm 63. The load-bearing arm 61 is located in the center between the two coupling arms 62. A second cylinder a2 is provided at the tip of each coupling arm 62. A third cylinder a3 is provided at the rear end of the rear arm 63. The second cylinder a2 passes through a coupling hole c1 of a coupling socket c provided on the back of the extrusion plate 41. The third cylinder a3 engages with a groove 52 of the button portion 50.

[0035] The force-applying arm 61 and the connecting rod 60 are integrally molded, and the second cylinder a2 provided on the connecting arm 62 is inserted into the connecting hole c1. When the button part 50 presses the connecting rod 60, the second cylinder a2 rotates relative to the connecting socket c. Therefore, it is necessary to allow the second cylinder a2 to move with a certain amount of clearance within the connecting hole c1. This clearance allows the delayed response of the button part 50 to press the extrusion plate 41. It is essential that the first cylinder a1 of the force-applying arm 61 is in close contact with the arc-shaped force-bearing surface 43. This allows the button part 50 to press the extrusion plate 41 without any gaps via the force-applying arm 61, thereby enabling a timely response from the button part 50 and controlling the hair-removing extrusion plate 40, improving the user experience for the comb user.

[0036] As shown in Figures 2, 3, 9, and 10, the button portion 50 comprises a button 51 that is slidable on the surface of the handle portion 20 and a coupling locking member 53. The button 51 is coupled with the coupling locking member 53. The coupling locking member 53 is provided with a groove 52.

[0037] The third cylinder a3 of the rear arm 63 is engaged with the groove 52 of the coupling lock member 53. When the button portion 50 is pressed, the coupling rod 60 pivots, and the third cylinder a3 can rotate relative to the groove 52 of the coupling lock member 53.

[0038] As shown in Figure 10, the tip of the force-bearing arm 61 is located above the tip of the connecting rod 60. The line connecting the center point of the first cylinder a1 and the center point of the third cylinder a3 and the line connecting the center point of the second cylinder a2 and the center point of the third cylinder a3 form an angle A. The line connecting the center point of the first cylinder a1 and the center point of the third cylinder a3 and the line of the longitudinal movement trajectory of the extrusion plate 41 form an angle B. As the extrusion plate 41 moves downward to extrude the hair, angle B gradually decreases. The arc-shaped force-bearing surface 43 and the second cylinder a2 have the same center. Due to this structure, the first cylinder a1 located at the tip of the force-bearing arm 61 is always in contact with the arc-shaped force-bearing surface 43. When the extrusion plate 41 and the connecting arm 62 are displaced, the force-bearing arm 61 does not interfere with the connecting arm 62.

[0039] It should be noted that as the button 51 of the button section 50 moves at a constant speed from the starting point to the ending point, the movement speed of the extrusion plate 41 gradually decreases. As angle B gradually decreases, the component of the force applied to the extrusion plate by the force-applying arm 61 gradually increases, and as a result, the button 51 requires a slightly larger pressing force at the starting point and a slightly smaller pressing force near the ending point.

[0040] While the connecting rod 60 moves, the first cylinder a1 of the force-applying arm 61 is in contact with the arc-shaped force-bearing surface 43 of the hair-removing extrusion plate 40, applying a pressing force to the arc-shaped force-bearing surface 43. The second cylinder a2 acts as a positioning point and is not directly involved in the action of pushing the extrusion plate 41. As the extrusion plate 41 moves downward, the third cylinder a3 rotates in the groove 52. As the angle B gradually decreases, the pressing force required to be applied to the button 51 gradually decreases.

[0041] Furthermore, as the extrusion plate 41 moves downward, the restoring force applied by the return spring 80 of the extrusion plate 41 gradually increases, thereby adjusting the force on the loading arm 61 in the above analysis to gradually decrease. As a result, the force applied by the user to press the button 51 remains essentially the same, which further improves the stability of the pressing force applied by the user to press the button, thereby improving the operability of pressing the button by the user.

[0042] The comb head 10 includes an outer shell 11. Two return springs 80 are positioned between the outer shell 11 and the extrusion plate 41. When the force applied to the button portion 50 by the user is released, the extrusion plate 41 returns to its initial position due to the action of the return springs 80.

[0043] Preferably, as shown in Figure 6, the blade holder portion 30 in this embodiment comprises a plate-shaped base 31 and a row of strip-shaped metal comb teeth 32 at the tip of the plate-shaped base 31.

[0044] As shown in Figure 7, the extrusion section 42 includes a gap extrusion section p for removing hair from the gaps between the comb teeth. As the extrusion section 42 moves downward, it can remove pet hair that has become stuck between the strip-shaped comb teeth 32.

[0045] The outer shell 11 includes a bottom outer shell k2 connected to the handle portion 20 and a head cover k1. The bottom outer shell k2 and the head cover k1 are secured together with fasteners.
