Description

Toothbrush capable of rapidly ejecting toothbrush head Technical Field The utility model relates to the technical field of toothbrushes, in particular to a toothbrush capable of rapidly ejecting a toothbrush head. Background Toothbrushes, which have been an important tool for personal oral care, have been traced back to thousands of years, early people used various natural materials such as wicker, animal bristles, etc. to clean teeth, and until the 15 th century, china Ming dynasty began to fix animal bristles (typically, pig bristles) to handles made of bamboo or bone, which is considered as a prototype of modern toothbrushes, however, until 1938, the invention of nylon fibers has led toothbrushes to a new era, dupont developed the first nylon toothbrushes, which have been rapidly popularized because of their soft and uniform characteristics. The existing toothbrush is convenient to carry, and the accommodating cavity is designed to store the brush head and the brush hair, however, when the toothbrush is needed to be used, a user needs to manually pull the brush head and the brush hair out of the accommodating cavity, the process cannot realize automatic ejection, and the use experience of the user is influenced due to lower efficiency of pulling out the brush head and the brush hair. Disclosure of utility model The utility model mainly aims to provide a toothbrush capable of rapidly ejecting a toothbrush head, and aims to solve the technical problem that when the existing toothbrush is needed to be used, a user needs to manually extract the toothbrush head and bristles from a containing cavity, and automatic ejection cannot be achieved in the process. In order to achieve the above purpose, the toothbrush provided by the utility model comprises a toothbrush handle, wherein a cavity is formed in the toothbrush handle, the toothbrush head is arranged in the cavity, and a limiting component which can facilitate the rapid ejection of the toothbrush head is arranged on the toothbrush handle; The utility model discloses a brush handle, including spacing subassembly, including the brush handle, spacing subassembly, including spacing hole, spacing groove, spout, fixed slot, stopper, gag lever post, extension spring, turn-button, thread groove and lead screw, the spacing hole set up in the inside of brush handle, and with the spacing hole is linked together, the spout set up in the inner wall of cavity, the fixed slot set up in the inner wall of cavity, and with the spout is linked together, the stopper is located on the brush head, and with the inner wall sliding connection of spout, the gag lever post is located on the brush head, and the other end runs through and extend to the inside of spacing hole, extension spring locates between the inner wall of cavity with the brush head, and the cover is located on the gag lever post, the turn-button is located on the spacing groove, and the other end extends to the outside of brush handle, the thread groove set up in the inside of turn-button, and with the spacing hole is linked together, the lead screw is located on the gag lever post. Optionally, the outer wall of the brush head is slidably connected with the inner wall of the cavity. Optionally, the height of the fixing groove is matched with the height of the limiting block.
