The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.

This embodiment relates to a handle structure of a toothbrush, which is mainly used for a toothbrush capable of automatically squeezing toothpaste, as shown in fig. 1 to 5, the toothbrush comprising: a cover body 500, a toothpaste barrel 100, a flow stopping valve 200 and a brush handle structure.

Specifically, the cap body 500 is assembled with the toothpaste barrel 100 by insertion. The toothpaste barrel 100 is integrally cylindrical, and the toothpaste barrel 100 and the brush handle structure are arranged to serve as a handle of a toothbrush for use, so that the toothpaste barrel 100 is convenient for a user to hold. The bottom of the toothpaste barrel 100 is detachably provided with a bottom cover 110, and a piston 120 is arranged in the toothpaste barrel 100, and the piston 120 is positioned between the toothpaste and the bottom cover 110. When the toothbrush is used for squeezing toothpaste, a negative pressure environment is formed in the brush holder structure, so that toothpaste in the toothpaste barrel 100 is sucked into the brush holder structure, at the moment, the air pressure in the toothpaste barrel 100 is reduced, and the bottom cover 110 and the toothpaste barrel 100 are not in sealed assembly, so that the piston 120 moves towards one side of the brush holder structure along the toothpaste barrel 100 under the pushing of the atmospheric pressure, and the toothpaste is squeezed towards one side of the brush holder structure until the toothpaste in the toothpaste barrel 100 is completely used up. The flow stopping valve 200 is disposed between the toothpaste barrel 100 and the brush holder structure, and the flow stopping valve 200 is used for preventing the toothpaste body flowing into the brush holder structure from flowing back into the toothpaste barrel 100.

Further, as shown in fig. 1-5, the handle structure includes: a brush bar 300 and a flexible lead-out member 400. Specifically, one end of the brush bar 300 is detachably assembled with the toothpaste barrel 100, and the other end is provided with bristles 310. And a hollow cavity is provided in the brush rod 300. The flexible guide 400 is mounted within the hollow cavity. A portion of the flexible guide 400 protrudes from the brush bar 300 to be pressed by a user, and another portion of the flexible guide 400 penetrates through the hollow cavity and extends toward the bristles 310 to squeeze toothpaste toward the bristles 310 when the flexible guide 400 is pressed.

Further, as shown in fig. 1 to 5, a through hole is formed at a side of the brush stick 300 adjacent to the bristles 310, and the flexible lead-out member 400 includes: a pressing section 410, a lead-out section 420, a paste outlet section 430 and a check valve 440.
