[0002] A toothbrush is a cleaning product, a handle-type brush that is used to add toothpaste to the brush and then repeatedly brush various parts of the teeth to maintain oral hygiene. Generally speaking, as long as a toothbrush is used for a period of time, a large number of bacteria will grow and multiply on the brush head of the toothbrush. These bacteria include Candida albicans, hemolytic streptococci, pneumococci, etc. In the process of using a toothbrush to clean the mouth, these bacteria will directly invade the human digestive tract and respiratory tract through the mouth, which may cause enteritis and lung infections, etc. At the same time, if they enter the human blood through the damaged oral mucosa, they will cause serious blood diseases; in addition, after a long period of use, the bristles on the toothbrush head will be worn short or worn off, and it is no longer suitable for continued use, so the toothbrush must be replaced every once in a while.

[0003] However, most of the current toothbrushes are of one-piece design, and all of them need to be discarded when they are replaced. This not only causes a waste of resources, but is also not conducive to recycling and increases the user's purchase cost. Later, some manufacturers developed a toothbrush with a replaceable brush head, but the replacement brush head still has a rod. When the service life of the brush head is reached, the rod also needs to be discarded. Compared with traditional toothbrushes, although it reduces a certain amount of resource waste and user purchase costs, it still causes a large waste of resources, and the reduction in user purchase costs is quite limited. Therefore, it is necessary to propose a new solution to solve the above problems. Utility Model Content

[0004] In view of this, the present invention aims to solve the deficiencies in the prior art and its main purpose is to provide a detachable brush head, which can effectively solve the problem that the brush head of the existing replaceable toothbrush still has a rod, which still causes a large waste of resources when discarded and the reduction of user's purchase cost is quite limited.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A detachable brush head comprises a rod and a brush head body; the rod is made of elastic material, the lower end surface of the rod is provided with an assembly cavity for assembly with a brush handle, the upper end of the rod is provided with an installation cavity, the inner side wall of the installation cavity is provided with a clamping portion; the brush head body comprises a fixing plate and bristles, the fixing plate is detachably installed in the installation cavity, a buckle portion is provided on the side of the fixing plate, and the buckle portion is buckled with the clamping portion; the bristles are arranged on the fixing plate.

[0007] As a preferred solution, the clamping portion is a convex portion, and the buckle portion is a clamping groove.

[0008] As a preferred solution, the clamping parts are multiple and spaced apart from each other, and correspondingly, the buckle parts are multiple and spaced apart from each other, and each buckle part is snap-fitted with the corresponding clamping part, so that the installation of the rod and the brush head body is more firm and reliable.

[0009] As a preferred solution, an inner wall of the installation cavity is concave to form a positioning cavity, and the side of the fixing plate is convex to form a positioning portion, which cooperates with the positioning cavity to prevent the position of the brush head body from shifting, and also prevents the user from installing the brush head body in the opposite direction.

[0010] As a preferred solution, the installation cavity is a cavity that runs through the front and rear surfaces. When the brush head body is installed, all the air in the installation cavity can be discharged, which is more conducive to the installation of the brush head body.

[0011] As a preferred solution, the cross-section of the installation cavity is T-shaped, and a limiting portion extends from the peripheral edge of the surface of the fixing plate, and the limiting portion abuts against the inner end surface of the installation cavity for limiting.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] By opening an assembly cavity for assembling with the brush handle on the lower end face of the rod, the brush head can be detachably installed on the brush handle, and the upper end of the rod is provided with an installation cavity, and the fixing plate is detachably installed in the installation cavity. When the service life of the brush head is reached, only the brush head body needs to be replaced, which further reduces resource waste and greatly reduces the user's purchase cost.
