Description

Technical Field

[0001] The utility model relates to the technical field of brushes, in particular to a brush which is convenient for switching between different brush heads. Background Art

[0002] A brush generally refers to a tool made of hair, palm, plastic wire, metal wire, etc. for removing dirt or applying ointment. It is usually long or oval in shape, and some have handles. Brushes are also called hair brushes. Brushes are divided into industrial brushes and civilian brushes according to their areas of use.

[0003] For example, a Chinese patent (publication number: CN201814083U) discloses a brush whose handle is vertically curved, which solves the problem of difficulty in applying force when brushing the inside of shoes; at the same time, the handle is provided with anti-slip particles to facilitate a firmer grip when the brush is used. At the same time, the handle and the brush handle are connected by a groove, so that the brush holder with different bristles can be easily replaced.

[0004] During the use of the brush, the bristles of the cleaning brush head are very easy to fall off after repeated use, thus affecting the use effect of the cleaning brush. The above-mentioned brush is convenient for replacing the brush head by providing a movably connected handle and brush handle. However, the stability of the above-mentioned brush for limiting the handle and brush handle by only providing a groove is too poor. If too much force is applied during use, the handle and brush handle are easy to fall off. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 In this embodiment, a brush that is convenient for switching between different brush heads includes a handle 1. A non-slip cover 2 is fixed to the outer surface of the handle 1, which can increase the friction between the handle 1 and the hand, making the hand more firmly hold the handle 1. A brush head 3 is arranged at the right end of the handle 1, and a hanging ring 5 is rotatably connected to the left end of the handle 1, so that the brush can be hooked up to be more tidy when not in use. An auxiliary mechanism 4 for switching different brush heads 3 is provided on the handle 1.

[0021] See also Figure 1-3 In order to facilitate switching of different brush heads 3, the auxiliary mechanism 4 includes an auxiliary component arranged on the brush head 3, a positioning component arranged on the auxiliary component, a supporting component arranged on the auxiliary component, and a limiting component arranged on the auxiliary component.

[0022] The auxiliary component includes a fixing seat 401 fixed on the left side of the brush head 3, a fixing groove 402 opened on the left side of the fixing seat 401 and into which the right end of the handle 1 is inserted, and the right end of the handle 1 is inserted into the fixing groove 402 and fits with the gap.

[0023] At the same time, the positioning component includes positioning grooves 403 which are opened at the upper and lower ends of the right side of the inner wall of the fixing seat 401 and are connected to the fixing groove 402. The positioning component also includes positioning blocks 407 fixed at the upper and lower ends of the right side of the handle 1. The two positioning blocks 407 are respectively inserted into the two positioning grooves 403 and matched with their gaps. The two positioning blocks 407 are symmetrically distributed up and down. The handle 1 can be positioned by using the positioning blocks 407 in conjunction with the positioning grooves 403, which is convenient for subsequent limiting of the handle 1.

[0024] In addition, the support assembly includes a groove 404 opened at the center of the right side of the inner wall of the fixing seat 401 and connected to the fixing groove 402, a support spring 405 fixed at the upper and lower ends of the groove 404, and a support plate 406 fixed on the left side of the two support springs 405. The elastic potential energy of the support spring 405 is used to act in reverse on the handle 1, thereby improving the stability of the handle 1 after being fixed.

[0025] It should be noted that the support plate 406 is a circular plate, and the left side of the support plate 406 fits tightly with the center of the right side of the handle 1. When the handle 1 is pushed into the fixing groove 402, the support plate 406 is squeezed to the left and the support spring 405 has elastic potential energy.

[0026] It can be understood that the limiting assembly includes a threaded groove 408 opened at the center of the right side of the front side of the handle 1, and the limiting assembly also includes a threaded hole 410 opened at the center of the left side of the front side of the fixing seat 401, a threaded rod 409 threadedly connected to the threaded hole 410 and extending into the threaded groove 408, and a screw handle 411 fixed to the front side of the threaded rod 409. By rotating the threaded rod 409 into the threaded groove 408 opened on the handle 1, the handle 1 can be limited, thereby fixing the brush head 3 and the handle 1 together.

[0027] The working principle of the above embodiment is:

[0028] If it is necessary to switch to a different brush head 3 during use, the threaded rod 409 can be rotated by the screw handle 411 to completely rotate the threaded rod 409 out of the threaded groove 408 of the handle 1, and then the brush head 3 can be separated from the handle 1 to remove the old brush head 3, and then the right end of the handle 1 can be inserted into the fixing groove 402 provided on the fixing seat 401 on the new brush head 3. In this process, the positioning block 407 is aligned with the positioning groove 403, and the positioning block 407 is completely pushed into the positioning groove 403. At the same time, the right end of the handle 1 squeezes the support plate 406, and the support plate 406 squeezes the support spring 405 and makes it have elastic potential energy in the left direction to act in the reverse direction on the handle 1, and then the threaded rod 409 is rotated by the screw handle 411 to rotate the back of the threaded rod 409 into the threaded groove 408, so that the new brush head 3 can be fixed, and its fixing effect is better, firmer and less likely to fall off.
