[0023] In order to better understand the technical solution of the present invention, the embodiments provided by the present invention are described in detail below with reference to the accompanying drawings.

[0024] See Figure 1-3 The embodiment of the utility model provides an electric toothbrush that can spray water, including an electric toothbrush head and a driven toothbrush handle 08. The electric toothbrush head includes a brush head shell 01, a tail cover 02, a brush head shell waterproof cover 03 and a brush head bristle 04. The brush head shell waterproof cover 03 is arranged outside the brush head shell 01. The brush head bristles 04 are planted on the brush head shell 01 through a copper sheet. The tail cover 02 is flush with the circumferential surface of the brush head shell 01. The stainless steel shaft 09 of the driven toothbrush handle 08 is inserted into the tail cover 02. A water outlet 01-1 is provided in the bristle area of ​​the brush head shell 01. The water outlet 01-1 is provided with a cylindrical step, and high-speed water pressure rushes out through the water outlet 01-1.

[0025] Therefore, the brush head shell of the electric toothbrush that can spray water provided by the utility model is provided with a water outlet in the hair-planting area, so that the user can also rinse the teeth with water while brushing. Specifically, the water outlet 01-1 is located at the front end of the hair-planting 04 part of the brush head, which is deeper into the mouth. The water outlet 01-1 does not require additional soft colloid to cooperate with. The water outlet 01-1 is 1-2 mm higher than the outer surface of the brush head, so that the water column is not easy to disperse, and the brush head has a good cleaning effect.

[0026] Based on the above embodiments, in other embodiments, further, refer to Figure 4 , the brush head housing 01 is provided with a water flow channel (see Figure 4(As shown by the arrow), an annular groove 01b is provided at the lower part of the brush head shell 01, and an open cavity 01c is provided at the upper part. The water outlet 01-1 is connected to the open cavity 01c. Specifically, the purpose of the open cavity 01c is to allow the water outlet 01-1 at the front of the mold to collide with the steel material of the open cavity at the rear, so that the mold has a long service life and will not be deformed due to the injection pressure during injection molding.

[0027] Based on the above embodiments, in other embodiments, further reference is made to Figure 6 The brush head shell waterproof cover 03 is provided with a silicone waterproof ring 05 and an ultrasonic line. The brush head shell waterproof cover 03 is provided with a circumferential bone position, and the silicone waterproof ring 05 is sleeved in the circumferential bone position. The rear part of the open cavity 01c is sealed by the ultrasonic line and the silicone waterproof ring 05. With such a double waterproof design, the product is not easy to leak, and the water will only be discharged through the water outlet 01-1.

[0028] Based on the above embodiments, in other embodiments, further reference is made to Figure 5 The tail cover 02 is provided with a rubber-coated soft body 06 and a stainless steel buckle spring piece 07. The rubber-coated soft body 06 is injection-molded on the tail cover 02 through a mold, and the stainless steel buckle spring piece 07 is inserted into the slot of the tail cover 02.

[0029] Based on the above embodiments, in other embodiments, further reference is made to Figure 7-8 The rubber-coated soft body 06 is provided with an inner annular convex rib 06a and an outer annular convex rib 06b. The inner annular convex rib 06a is sleeved on the stainless steel shaft 09 that drives the toothbrush handle 08. The convex rib on the rubber-coated soft body 06 is interference fit with the brush head shell to ensure that the high-pressure water flow will not leak. The stainless steel shaft 09 is the power transmission shaft. The stainless steel shaft 09 is provided with a stainless steel shaft hole 09a, and the high-speed water flow can rush out from the stainless steel shaft hole 09a.

[0030] On the basis of the above embodiments, in other embodiments, further, an annular ridge 02a is provided on the tail cover 02, and an annular groove 01b is provided on the brush head shell 01. The annular ridge 02a of the tail cover 02 is buckled in the annular groove 01b of the brush head shell 01, so that the tail cover 02 cannot be pulled out from the brush head shell 01.

[0031] On the basis of the above embodiments, in other embodiments, further, the stainless steel snap spring piece 7 adopts a convex design, and the buckle point can be deformed up and down. Specifically, the stainless steel snap spring piece 07 is provided with a buckle point 07a, and the buckle point 07a is engaged with the groove 09b on the stainless steel shaft 09 to prevent the entire toothbrush head from rotating, and the toothbrush head will not be washed out due to the high-pressure water outlet in the water outlet hole 09a of the stainless steel shaft 09.

[0032] Therefore, through the above structure, the stainless steel buckle spring piece cooperates with the groove of the driving handle, and the annular convex bone on the tail cover cooperates with the annular groove of the brush head shell, which effectively transmits the mechanical vibration energy of the driving handle to the toothbrush head and reduces noise. The insertion and removal of the stainless steel buckle spring piece is conducive to improving the service life of the electric toothbrush. The cooperation between the rubberized soft body in the tail cover and the drive shaft can also achieve better water leakage prevention, effectively solving the problems of water leakage and easy falling off of the buckle during use of the existing electric toothbrush, and the short service life of the mold.

[0033] The above is a detailed introduction to an electric toothbrush capable of spraying water provided by an embodiment of the present invention. For a person skilled in the art, according to the concept of the embodiment of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
