[0031] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0032] See also Figure 1 to Figure 2 As shown, the utility model is an automatic toothpaste squeezing toothbrush with a teeth washing function, comprising a brush head 1 and a handle 2 detachably connected to the brush head 1; the brush head 1 is provided with a nozzle 11 for spraying water, a liquid outlet 12 for outputting toothpaste, a first pipe 13 connected to the nozzle 11, and a second pipe 14 connected to the liquid outlet 12; the handle 2 is provided with a water spraying device 3, a toothpaste squeezing device 4 and an electric control device 5, the electric control device 5 is electrically connected to the water spraying device 3 and the toothpaste squeezing device 4 respectively, the water spraying device 3 is connected to the nozzle 11 via the first pipe 13, and the toothpaste squeezing device 4 is connected to the liquid outlet 12 via the second pipe 14. In this embodiment, the brush head 1 is detachable and replaceable, and when the bristles 17 are worn, a new matching brush head 1 can be replaced. The nozzle 11 can be arranged at the top of the brush head 1 or between the bristles 17, and the liquid outlet 12 is arranged between the bristles 17. The electric control device 5 is a control system of a common electric toothbrush. The difference is that the control modes of the electric control device 5 are a toothpaste squeezing mode and a teeth washing mode. The priority selection button 27 triggers the electric control device 5 to switch the mode and turn it on.

[0033] Before brushing teeth, the toothpaste squeezing device 4 can be controlled by the electronic control device 5 to squeeze out toothpaste, and the toothpaste is squeezed out of the brush head 1 from the liquid outlet 12 through the second pipe 14, so as to brush teeth; if teeth washing is required, the water spraying device 3 can be controlled by the electronic control device 5 to spray high-pressure water flow, and the high-pressure water flow is ejected from the nozzle 11 through the first pipe 13, which can further clean the user's teeth. The automatic toothpaste squeezing toothbrush with teeth washing function combines a tooth washer with a toothbrush that automatically squeezes out toothpaste, solves the problem that the tooth washer is separated from the toothbrush and toothpaste, occupies a large space and is inconvenient to carry and use, and achieves the effect of one thing with multiple uses, saving space and being convenient to use and carry.

[0034] See also Figure 2As shown, the brush head 1 includes a rod body 15, a head 16 of an integral structure with the rod body 15, and bristles 17 arranged on the head 16. The nozzle 11 and the liquid outlet 12 are both arranged on the head 16 and located between the bristles 17. The first pipe 13 and the second pipe 14 are arranged inside the rod body 15. The bottom of the rod body 15 is provided with a first hook 18, which protrudes from the bottom of the rod body 15, and the hook tip of the first hook 18 is arranged outward. The first pipe 13 and the second pipe 14 are parallel to each other, with the bristles 17 side as the front side. Preferably, the first pipe 13 and the second pipe 14 are arranged in front and back positions, and the first pipe 13 is located at the rear side so that the nozzle 11 can be located above the liquid outlet 12 to avoid mutual interference between the first pipe 13 and the second pipe 14. The inner diameter of the lower end of the first pipe 13 is larger than the inner diameter of the upper end, so that the lower end is plugged with the water suction pipe 32; the inner diameter of the lower end of the second pipe 14 is larger than the inner diameter of the upper end, so that the lower end is plugged with the infusion pipe 43.

[0035] See also Figure 2 As shown, the handle 2 includes a main body, which is provided with a housing chamber 21 for accommodating a water spray device 3, a toothpaste squeezing device 4 and an electronic control device 5. The upper and lower ends of the housing chamber 21 are waterproof and sealed to prevent water vapor from entering the housing chamber 21 during use, thereby causing a short circuit in the electronic control device 5; the upper end of the main body is provided with a first card slot 22 for accommodating a first card hook 18. When the brush head 1 and the handle 2 are installed, the first card hook 18 is inserted into the first card slot 22, so that the brush head 1 is firmly connected to the handle 2. When the brush head 1 needs to be replaced, the old brush head 1 only needs to be unplugged from the handle 2, and then the new brush head 1 can be inserted; the lower end of the main body is provided with a second card slot 23, and the second card slot 23 is used to clamp the water bottle 31 and the toothpaste bottle 41.

[0036] See also Figure 2 As shown, the water spray device 3 includes a water bottle 31, a water suction pipe 32 and a high-pressure water pump 33. The water bottle 31 is clamped at the lower end of the main body. The upper section of the water suction pipe 32 is connected to the first pipeline 13 and the high-pressure water pump 33 respectively, and the lower section of the water suction pipe 32 is connected to the high-pressure water pump 33 and the water bottle 31 respectively.

The upper section of the water suction pipe 32 protrudes from the top of the accommodating cavity 21 for plugging into the first pipeline 13. The lower end of the water suction pipe 32 protrudes from the bottom of the accommodating cavity 21 for extending into the water bottle 31, and the end of the water suction pipe 32 directly reaches the bottom of the water bottle 31 so as to fully suck out the toothwashing liquid in the water bottle 31. When using the teeth cleaning function of the toothbrush, the water bottle 31 can be removed from the handle 2, and then the water bottle 31 is filled with tooth cleaning liquid (such as clean water), and the water bottle 31 is reinstalled on the handle 2. The high-pressure water pump 33 is controlled by the electronic control device 5 to operate. The high-pressure water pump 33 draws the tooth cleaning liquid in the water bottle 31 through the suction pipe 32 to form a high-pressure water flow and reaches the nozzle 11 through the first pipe 13, and is finally sprayed out from the nozzle 11 and sprayed onto the user's teeth for rinsing and cleaning.

[0037] See also Figure 2 As shown, the toothpaste squeezing device 4 includes a toothpaste bottle 41, a foam pump 42 and an infusion tube 43.

The foam pump 42 is installed in the accommodating cavity 21. The upper section of the infusion tube 43 protrudes from the top of the accommodating cavity 21 for plugging into the second pipeline 14. The lower end of the infusion tube 43 protrudes from the bottom of the accommodating cavity 21 for extending into the toothpaste bottle 41, and the end of the infusion tube 43 directly reaches the bottom of the toothpaste bottle 41 so as to fully suck out the toothpaste in the toothpaste bottle 41. When using the toothbrush daily, the toothpaste bottle 41 can be filled with toothpaste at one time. Each time you brush your teeth, you only need to control the foam pump 42 through the electronic control device 5 to extract an appropriate amount of toothpaste in the toothpaste bottle 41 and turn it into foam, and then output it from the liquid outlet 12 through the second pipe 14 to fill between the bristles 17, and then you can use the bristles 17 to brush your teeth; when the toothpaste in the toothpaste bottle 41 is used up or the remaining amount is small after using it for a period of time, the toothpaste bottle 41 can be disassembled to refill the toothpaste.

[0038] See also Figure 2 As shown, the shape of the water bottle 31 and the shape of the toothpaste bottle 41 are both semi-cylindrical, and the water bottle 31 and the toothpaste bottle 41 are combined to form a complete cylinder.
