[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Please see Figures 1-6 This utility model provides a technical solution: a multi-functional flushing toothbrush, including a handle 1, and further comprising:
[0025] Brush head 2 is fixedly installed at one end of handle 1. Brush bristles 3 are fixedly installed inside brush head 2. Brush bristles 4 are fixedly installed on both sides of brush bristles 3 inside brush head 2. Top brush 5 is fixedly installed on top of brush head 2. Water channel 6 is opened inside brush head 2 above brush bristles 3. Water outlet holes 8 are symmetrically opened at the bottom of water channel 6. Connecting grooves 9 are symmetrically opened on both sides of water outlet holes 8 inside brush head 2. Water outlet hole 10 is opened on one side of connecting groove 9. Water inlet groove 7 is opened inside handle 1 and communicates with water channel 6.
[0026] When using the brush, the user can hold the handle 1 and brush their teeth using the bristles 3 and 4 on the brush head 2. Since the two bristles 4 are inclined, the bottom of the bristles 3 will rest against the top surface of the teeth, while one side of each bristle 4 will rest against the two sides of the teeth. This allows the bristles 3 and 4 to brush all three surfaces of the teeth at once when the brush head 2 moves, thus speeding up the brushing process and cleaning the teeth more thoroughly.
[0027] Meanwhile, the water in the inlet tank 7 enters the flow tank 6, and the water in the flow tank 6 flows into the four connecting tanks 9. At the same time, the water in the flow tank 6 also flows into the bristles 3 through the two water outlet holes 8. The water in the four connecting tanks 9 flows out through the four water outlet holes 10, and then flows into the two bristles 4. This ensures that the bristles 3 and the two bristles 4 can be rinsed, and that the three sides of the teeth can be rinsed, so that the teeth can be brushed more clean.
[0028] This embodiment also includes:
[0029] Water inlet pipe 15 is fixedly installed at the other end of handle 1. Connector 16 is fixedly installed at one end of water inlet pipe 15. Sealing cap 11 is fixedly installed on the top of connector 16. Insertion plate 12 is fixedly installed on one side of sealing cap 11. Sealing ring 13 is fixedly installed on one side of sealing cap 11 and on the periphery of insertion plate 12.
[0030] Personnel can connect the connector 16 to a water source, allowing water to flow sequentially through the connector 16, the inlet pipe 15, and the inlet tank 7 into the water tank 6. When not in use, personnel can rotate the sealing cover 11 and insert the plug plate 12 into one end of the connector 16. At this time, the sealing ring 13 will adhere to one end of the connector 16, thereby sealing one end of the connector 16 and ensuring that no dust enters the connector 16 when it is not in use.
[0031] In this embodiment, the plug plate 12 is plugged into one end of the connector 16, and the diameter of the sealing ring 13 is equal to the diameter of the connector 16.
[0032] Specifically, this ensures that the plug plate 12 can be inserted into the connector 16, and that the sealing ring 13 can seal one end of the connector 16.
[0033] In this embodiment, several anti-slip rings 14 are fixedly installed around the handle 1.
[0034] Among them, several anti-slip rings 14 can increase friction when the person holds the handle 1, so as to prevent the handle 1 from slipping.
[0035] In this embodiment, the handle 1 and the brush head 2 are integrally formed.
[0036] This includes ensuring the structural stability of the handle 1 and the brush head 2.
[0037] In this embodiment, the second bristle 4 has an inclined structure.
[0038] This ensures that the two bristles can brush both sides of the teeth.
[0039] In this embodiment, the water trough 6 is connected to the four connecting grooves 9, the second water outlet 10 is connected to the second bristle 4, and the first water outlet 8 is connected to the first bristle 3.
[0040] Specifically, it ensures that the water in the water tank 6 can flow into the four connecting tanks 9, that the water flowing out of the second water outlet 10 can rinse the second bristle 4, and that the water flowing out of the first water outlet 8 can rinse the first bristle 3.
[0041] Working principle: When in use, the user can hold the handle 1 and brush their teeth through the bristles 3 and 4 on the brush head 2. Since the two bristles 4 are inclined, the bottom of the bristles 3 will press against the top surface of the teeth, while one side of each bristle 4 will press against the two sides of the teeth respectively. This allows the bristles 3 and 4 to brush all three surfaces of the teeth at once when the brush head 2 moves, thus speeding up the brushing efficiency and cleaning the teeth more thoroughly. The top bristles 5 can also be used to brush the tongue.
[0042] Meanwhile, personnel can connect the connector 16 to a water source, allowing water to flow sequentially through the connector 16, the inlet pipe 15, and the inlet tank 7 into the water flow tank 6. The water in the water flow tank 6 will then flow into the four connecting tanks 9, and simultaneously, the water in the water flow tank 6 will flow into the brush bristles 3 through the two outlet holes 1 8. The water in the four connecting tanks 9 will then flow out through the four outlet holes 2 10, flowing into the two brush bristles 2 4. This ensures that the brush bristles 1 3 and the two brush bristles 2 4 can be rinsed, and that the three surfaces of the teeth can be rinsed, resulting in cleaner teeth.
