The lever 11 is mounted on the main shaft of the ending gear 52. When the motor 4 rotates, it drives the starting gear 51 to rotate, which in turn drives the ending gear 52 to rotate. The ending gear 52 then drives the lever 11 to rotate, ensuring that one motor 4 simultaneously drives the levers 11 on both sides to rotate, and that the left and right levers 11 are synchronized, allowing both ends of the comb 10 to start synchronously, effectively reducing the torque borne by the comb 10.

[0057] Furthermore, the water tank assembly of this utility model patent, such as Figure 3 As shown, the comb consists of a bracket 1, a drain valve 2, a water inlet valve 6, a water tank 7, a water pump 8, a hair dryer 9, and a guide rail 12. The bracket 1 supports the person's head, maintaining a suitable height. The drain valve 2 and the water inlet valve 6 control the water inlet and outlet of the water tank. The water pump 8 draws water from the tank and sprays it onto the person's head to keep it moist. The hair dryer 9 blows hot air onto the head to dry the hair. The guide rail 12 controls the movement trajectory of the comb.

[0058] Furthermore, such as Figure 4 As shown, the guide plate 12 has two equally spaced, closed annular grooves of uniform width. One groove is located on the outer ring and is called the outer groove 121, and the other groove is located on the inner ring and is called the inner groove 122. Both the outer groove 121 and the inner groove 122 are composed of the following six tangent straight grooves and arc grooves: groove a1 in the upper horizontal straight groove of the outer groove 121 and groove b1 in the inner groove 122; groove a5 in the lower horizontal straight groove of the outer groove 121 and groove b5 in the inner groove 122; groove a3 in the outer groove 121 and groove b3 in the inner groove 122 located on one side of the concave groove; groove a6 in the outer groove 121 and groove b6 in the inner groove 122 located on the other side of the convex groove; grooves a2 and b2 that transition from grooves a1 and b1 to grooves a3 and b3 respectively; and grooves a4 and b4 that transition from grooves a3 and b3 to grooves a5 and b5 respectively. The transition between adjacent straight grooves and circular grooves, or between circular grooves, is smooth. When the outer groove 121 and the inner groove 122 are straight lines, they are parallel to each other, i.e., a1 is parallel to b1, and a5 is parallel to b5. When the outer groove 121 and the inner groove 122 are circular arcs, their arcs share the same center, i.e., a2 and b2, a3 and b3, a4 and b4, and a6 and b6. With this structure, the spacing between different positions of the outer groove 121 and the inner groove 122 is equal.

[0059] Furthermore, the cross-sectional view of Comb 10 is as follows: Figure 5 Enlarged view of point A as shown Figure 6 As shown, the 3D diagram is as follows Figure 7 Enlarged view of point B as shown Figure 8 As shown, the comb 10 includes a comb frame 101 and a plurality of comb teeth 102 disposed on the inner surface of the comb frame 101. A comb frame shaft 103 is disposed at each end of the comb frame 101. A dial shaft 104 is disposed at the outer end of the comb frame shaft 103. A connector 105 is disposed at the end of the dial shaft 104. The connector 105 is connected to the comb frame shaft 103 by a pin 108. An outer shaft 106 and an inner shaft 107 are disposed at each end of the connector 105. The outer shaft 106 is coaxial with the dial shaft 104 and the comb frame shaft 103. The center distance between the outer shaft 106 and the inner shaft 107 is equal to the center distance between the outer groove 121 and the inner groove 122. The comb frame 101 is arched. The comb teeth 102 are made of a material with a certain elasticity. The top of the comb teeth 102 is arc-shaped.

[0060] Furthermore, a balance block 109 is provided on the other side of the comb frame shaft 103 to keep the weight on both sides of the comb frame shaft 103 balanced, ensuring that the center of gravity of the comb 10 is on the center line of the comb frame shaft 103.

[0061] Furthermore, a three-dimensional view of lever 11 is shown below. Figure 9 As shown, a rotating shaft 111 is provided at one end of the lever 11, and a receiving groove 112 is provided on the lever 11.

[0062] Furthermore, the installation method of the lever 11 with the comb 10 and the guide plate 12 is as follows: Figure 10 As shown, the enlarged view at point C is as follows: Figure 11 As shown, the outer shaft 106 is disposed in the outer groove 121, the inner shaft 107 is disposed in the inner groove 122, and the dial 104 passes through the receiving groove 112.

[0063] Furthermore, a three-dimensional diagram showing the installation method of drain valve 2, water tank 7, gear 5, long shaft 41, motor 4, comb 10, guide rail plate 12, and lever 11 is shown below. Figure 12 As shown, a guide rail plate 12 and a lever 11 are installed on the inner sidewalls of the left and right sides of the water tank 7. A set of gears 5 are installed on the outer sidewalls of the left and right sides of the water tank 7. The starting gears 51 of the two sets of gears 5 are connected by a long shaft 41. A motor 4 is installed at one end of the long shaft. The main shaft of the ending gear 52 is coaxial with the main shaft 111 of the lever. The guide rail plate structure, gears, levers and other structures on the left and right sides of the water tank are symmetrical to each other.

[0064] Furthermore, when the motor 4 rotates, it drives the lever 11 to rotate through the gear 5. The receiving groove 112 drives the lever shaft 104 to move. The lever shaft 104 drives the outer shaft 106 and the inner shaft 107 to move in the outer groove 121 and the inner groove 122, respectively.

[0065] Furthermore, the center distance between the outer groove 121 and the inner groove 122 is equal to the center distance between the outer shaft 106 and the inner shaft 107. When the outer shaft 106 and the inner shaft 107 move along the straight groove 1, the comb 10 moves in a translational manner, and the direction of the comb teeth 102 remains unchanged. When the outer shaft 106 and the inner shaft 107 move along the arc groove of the guide plate 12, since the arcs of the inner and outer grooves are concentric, the direction of the comb teeth 102 (or the direction of the reverse extension line) always points to the center of the arc, causing the comb 10 to swing, thereby completing the shampooing and combing actions.

[0066] Furthermore, when motor 4 changes its rotation direction, comb 10 will change the direction in which it combs the hair.

[0067] Furthermore, the controller 15 selects different speed settings, and the comb 10 will change the speed at which it combs the hair.

[0068] The comb's movement process:

[0069] Motor 4 drives gear 5 to rotate, gear 5 drives lever 11 to rotate, lever 11 drives shaft 104 to move, and shaft 104 drives the outer shaft 106 and inner shaft 107 at both ends of comb 10 to move in the outer groove 121 and inner groove 122 of guide plate 12, respectively. When the outer groove 121 and inner groove 122 are straight grooves, comb 10 moves parallel. When the outer groove 121 and inner groove 122 are arc grooves, comb 10 also flips during the movement, thus completing the combing action. One rotation of lever 11 drives comb 10 to complete one cycle. The movement process of comb is shown below.

[0070] Step 1: As Figure 13 As shown, the comb 10 is in the starting position, the outer shaft 106 is located at the right end of the straight groove a1 of the outer groove 121, the inner shaft 107 is located at the right end of the straight groove b1 of the inner groove 122, and the comb teeth 102 are facing upward.

[0071] Step 2: As Figure 14 As shown, the outer shaft 106 moves parallel to the left along the straight groove a1 of the outer groove 121 to the point where the straight groove a1 and the circular groove a2 are tangent, and the inner shaft 107 moves parallel to the left along the straight groove b1 of the inner groove 122 to the point where the straight groove b1 and the circular groove b2 are tangent, with the comb teeth 102 facing upward.

[0072] Step 3: As Figure 15 As shown, the outer shaft 106 rotates along the transition arc groove a2 of the outer groove 121 to the tangent point of the arc groove a2 and the arc groove a3, and the inner shaft 107 rotates along the transition arc groove b2 of the inner groove 122 to the tangent point of the arc groove b2 and the arc groove b3, with the comb teeth 102 facing the head.

[0073] Step 4: As Figure 16As shown, the outer shaft 106 rotates along the arc groove a3 of the outer groove 121 to the midpoint of the arc groove a3, and the inner shaft 107 rotates along the arc groove b3 of the inner groove 122 to the midpoint of the arc groove b3. The comb teeth 102 are oriented towards the head in the horizontal direction.

[0074] Step 5: As Figure 17 As shown, the outer shaft 106 rotates along the arc groove a3 of the outer groove 121 to the tangent point of the arc groove a3 and the arc groove a4, and the inner shaft 107 rotates along the arc groove b3 of the inner groove 122 to the tangent point of the arc groove b3 and the arc groove b4, and the comb teeth 102 face the head obliquely upward.

[0075] Step 6: As Figure 18 As shown, the outer shaft 106 rotates along the transition arc groove a4 of the outer groove 121 to the tangent point of the arc groove a4 and the arc groove a5, and the inner shaft 107 rotates along the transition arc groove b4 of the inner groove 122 to the tangent point of the arc groove b4 and the arc groove b5, with the comb teeth 102 facing downward.

[0076] Step 7: As Figure 19 As shown, the outer shaft 106 moves parallel to the right along the straight groove a5 of the outer groove 121 to the point where the straight groove a5 and the circular groove a6 are tangent, and the inner shaft 107 moves parallel to the right along the straight groove b5 of the inner groove 122 to the point where the straight groove b5 and the circular groove b6 are tangent, with the comb teeth 102 facing downwards.

[0077] Step 8: As Figure 20 As shown, the outer shaft 106 rotates along the arc groove a6 of the outer groove 121 to the midpoint of the arc groove a6, and the inner shaft 107 rotates along the arc groove b6 of the inner groove 122 to the midpoint of the arc groove b6.
