[0018] The working principle of this utility model:

[0019] The outer casing of the connecting part has holes through which the sliding block passes and is installed in the sliding groove. The rotating shaft passes through the holes and is installed inside the casing. When the drive shaft rotates, it drives the reciprocating screw to rotate. Because the sliding block is located in the sliding groove and is constrained by the guiding restriction of the casing, it will drive the sliding block to reciprocate along the axis of the drive shaft. Since the sliding block is fixed to the bottom surface of the translation brush head, it will drive the translation brush head to reciprocate.

[0020] When the drive shaft rotates, the first gear at the top of the reciprocating lead screw also rotates. Since the first gear is perpendicular to and meshes with the second gear, the first gear transmits the force of the drive shaft's rotation to the second gear. Because the second gear is fixed to the 360° rotating brush head, the 360° rotating brush head also rotates when the second gear rotates.

[0021] Furthermore, due to the groove design inside the translation brush head, the 360° rotating brush head remains inside the translation brush head as the translation brush head moves.

[0022] The distance of the reciprocating motion of the translational brush head is 5–12 mm. The distance of the reciprocating motion of the translational brush head is adjustable, simulating the distance of manual brushing of teeth, which is 5–12 mm.

[0023] The advantages of this utility model are:

[0024] 1. This utility model combines a horizontal brush head with a 360° rotating brush head, which can achieve a multi-directional teeth cleaning effect. The horizontal brush head will collect and push back the toothpaste that is thrown out by the 360° rotating brush head, which can prolong the time that the toothpaste remains on the 360° rotating brush head and more effectively improve the teeth cleaning effect.

[0025] 2. The translational brush head of this utility model can be U-shaped, which can effectively wrap around three surfaces of the teeth, and the brush head can reciprocate, which can effectively clean teeth;

[0026] 3. The brush head of this invention is elastic, which allows it to better conform to the tooth surface;

[0027] 4. This utility model has a simple structure and low production cost, and can be quickly launched to the market. Attached Figure Description

Detailed Implementation

[0037] Example 1: As shown in Figures 1-3, a 360° rotating reciprocating electric toothbrush head includes a handheld part 1 and an electric toothbrush head 2. The electric toothbrush handheld part 1 includes a power supply, a motor, and a control button. The control button controls the motor's start and stop, the power supply provides electrical energy to the motor, and the motor provides power to the drive shaft 8 of the connecting part of the electric toothbrush head 2.

[0038] The electric toothbrush head 2 includes a brush head and a connecting part. The brush head includes a translating brush head 3 and a 360° rotating brush head 4. The translating brush head 3 is slidably connected to the connecting part, and the 360° rotating brush head 4 is rotatably connected to the connecting part.

[0039] The connecting part includes a housing 5, a reciprocating lead screw 6, and a drive shaft 8. The reciprocating lead screw 6 is fixedly mounted on the end of the drive shaft 8. A sliding groove 12 is provided on the reciprocating lead screw 6, and a first gear 9 is provided at the end of the reciprocating lead screw 6.

[0040] The 360° rotating brush head 4 is located inside the translation brush head 3. The translation brush head 3 has a groove 10, which cooperates with the 360° rotating brush head 4.

[0041] The translation brush head 3 is a U-shaped brush head 7. A sliding block is fixedly installed at the bottom of the translation brush head 3, and the sliding block cooperates with the sliding groove 12.

[0042] The 360° rotating brush head 4 includes a circular base plate 13, a second gear 14, and a rotating shaft 15. The circular base plate 13 and the rotating shaft 15 are respectively fixed on both sides of the second gear 14. The circular base plate 13, the second gear 14, and the rotating shaft 15 are coaxially arranged. The end of the rotating shaft 15 is rotatably connected to the inside of the outer casing 5. The second gear 14 meshes with the first gear 9.

[0043] The end of the rotating shaft 15 can be rotatably connected to the housing 5 using a bearing. The first gear 9 and the second gear 14 are perpendicular to each other and mesh.

[0044] The U-shaped brush head 7 includes a bottom surface and two side surfaces arranged parallel to the connecting part. The two side surfaces are fixedly arranged on both sides of the bottom surface to form a U-shape. Brush bristles are evenly arranged on the bottom surface and side surfaces, and the brush bristles are all arranged inward to form a U-shape.

[0045] The bottom and sides of the brush head are made of elastic plastic, providing a degree of flexibility during use and effectively wrapping around the teeth. The bristles are made of soft rubber, nylon fibers, and other materials.

[0046] It includes an auxiliary slider 11, which is fixed to the bottom of the translation brush head 3. The auxiliary slider 11 has a concave arc surface, which cooperates with the reciprocating lead screw 6. The sliding block is fixed on the arc surface.

[0047] How to use this embodiment:

[0048] The outer casing 5 of the connecting part has a hole through which the sliding block is installed in the sliding groove 12, and the rotating shaft 15 is installed inside the outer casing 5 through the hole. When the control button on the handheld part 1 is activated, the drive shaft 8 rotates. When the drive shaft 8 rotates, it drives the reciprocating screw 6 to rotate. Since the sliding block is set in the sliding groove 12 and is restricted by the guide of the outer casing 5, it will drive the sliding block to reciprocate along the axis of the drive shaft 8. Since the sliding block is fixed to the bottom surface of the translation brush head 3, it will drive the translation brush head 3 to reciprocate.

[0049] When the drive shaft 8 rotates, the first gear 9 at the top of the reciprocating lead screw 6 also rotates. Since the first gear 9 is perpendicular to and meshes with the second gear 14, the first gear 9 transmits the force of the rotation of the drive shaft 8 to the second gear 14. Since the second gear 14 is fixed to the 360° rotating brush head 4, when the second gear 14 rotates, the 360° rotating brush head 4 also rotates.

[0050] Furthermore, due to the setting of the groove 10 inside the translation brush head 3, when the translation brush head 3 is displaced, the 360° rotating brush head 4 remains inside the translation brush head 3.

[0051] In this embodiment, the combination of the U-shaped brush head 7 and the 360° rotating brush head 4 allows for brushing of three surfaces of the teeth simultaneously, and the translational brush head 3 has good effective displacement, resulting in excellent teeth cleaning effect.

[0052] Since the 360° rotating brush head 4 is always located inside the translational brush head 3, the translational brush head 3 will collect and push back the toothpaste that is flung out by the 360° rotating brush head 4, which can prolong the time that the toothpaste remains on the 360° rotating brush head 4, thereby achieving a better cleaning effect.

[0053] Example 2, as Figure 4-6 As shown, a 360° rotating reciprocating translation electric toothbrush head differs from Embodiment 1 in that the translation brush head 3 is a flat brush head 17, including a base plate arranged parallel to the connecting part, and bristles are evenly arranged on the base plate.
