Description

Technical Field

[0001] The utility model belongs to the technical field of dental brushes, in particular to a novel dental brush. Background Art

[0002] A dental brush is a tool used to apply various dental materials, such as desensitizing agents such as fluoride. Dental brushes are produced in Germany and are mainly composed of a brush handle and a brush head. The brush head is made of fiber material, and the brush handle is made of polypropylene material.

[0003] Today's dental brushes consist of two parts: a brush handle and a brush head. Most dental brushes connect the brush handle and the brush head through a threaded connection, making it easy to replace the brush head. There is no complete fixing mechanism inside. When a dentist uses a dental brush to apply dental materials, the brush head is prone to rotation. Since the brush handle and the brush head are connected through a threaded connection, it is easy for the connection to loosen during use, which greatly reduces the physical feel of the dental brush when in use and results in poor results. Utility Model Content

[0004] The purpose of the present utility model is to solve the problem that the current dental brush consists of a brush handle and a brush head. Most dental brushes connect the brush handle and the brush head by a threaded connection, so that the brush head can be easily replaced. There is no perfect fixing mechanism inside the brush. When the dentist uses the dental brush to apply dental materials, the brush head is prone to rotation. Since the brush handle and the brush head are connected by a threaded connection, it is easy to cause the connection to loosen during use, which greatly reduces the physical feel of the dental brush when in use and the use effect is poor. A new dental brush is proposed.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a new dental brush, comprising a brush handle and a brush head, wherein the side wall of the brush handle is provided with an anti-slip component, and the bottom end of the brush head is provided with a fixing component;

[0006] The fixing assembly includes a threaded barrel, which is fixedly installed on the bottom end of the brush head. A threaded column is fixedly installed on the top end of the brush handle. A fixing block is fixedly installed on one end of the threaded column. A socket is provided on the side wall of the fixing block. A telescopic connecting rod and a spring rod are fixedly installed on the inner wall of the threaded barrel.

[0007] As a further description of the above technical solution:

[0008] A first long plate and a second long plate are fixedly mounted on the other end of the telescopic connecting rod and the other end of the spring rod, and a first clamping plate is fixedly mounted on the side wall of one end of the first long plate.

[0009] As a further description of the above technical solution:

[0010] A second clamping plate is fixedly mounted on the side wall of one end of the second long plate, and latches are fixedly mounted on the outer walls of the first clamping plate and the second clamping plate.

[0011] As a further description of the above technical solution:

[0012] A first pressure rod is fixedly mounted on the outer wall of the first long plate. The first pressure rod passes through a through hole provided on the outer wall of the second long plate. The first pressure rod passes through a through hole provided on one side of the threaded barrel.

[0013] As a further description of the above technical solution:

[0014] A second pressing rod is fixedly mounted on the outer wall of the second long plate. The second pressing rod passes through a through hole provided on the outer wall of the first long plate. The second pressing rod passes through a through hole provided on the other side of the threaded cylinder.

[0015] As a further description of the above technical solution:

[0016] The anti-slip component includes a sponge sheet, a mounting groove is provided on the side wall of the brush handle, the sponge sheet is fixedly installed on the inner wall of the mounting groove, a rubber sheet is fixedly installed on the outer wall of the sponge sheet, and anti-slip convex particles are provided on the outer wall of the rubber sheet.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. In the utility model, a fixing assembly is provided. First, by pressing the first pressure rod and the second pressure rod, the first pressure rod passes through the through hole provided on the second long plate. When the first pressure rod is displaced, the first long plate is displaced, and the first long plate drives the first clamping plate provided at one end thereof to displace. The second pressure rod passes through the through hole provided on the first long plate. When the second pressure rod is displaced, the second long plate is displaced, and the second clamping plate provided at one end thereof is displaced, so that the first clamping plate and the second clamping plate are displaced toward each other, and the gap between the first clamping plate and the second clamping plate is expanded. At this time, the first long plate and the second long plate will press against the clamping plate installed on the side wall of the threaded cylinder. The spring rod is squeezed to form a compressed state, and the threaded cylinder set at the bottom end of the brush head and the threaded column set at the top end of the brush handle are threadedly installed. After the installation is completed, the first pressure rod and the second pressure rod can be loosened, and the first splint and the second splint are reset by the elastic force of the spring rod to clamp the fixed block. The pins set on the side walls of the first splint and the second splint are inserted into the sockets set on the side walls of the fixed block to complete the installation of the dental brush. Through this design, the connection between the brush handle and the brush head is effectively fixed, and the loosening of the connection during use is avoided, which greatly improves the physical feel of the dental brush during use and has a good use effect.

[0019] 2. In the present invention, an anti-slip component is provided, and a sponge sheet is installed on the mounting groove provided on the side wall of the brush handle, so that when the dentist holds the brush handle, the sponge sheet fits the dentist's hand, and the sponge sheet has a certain softness to prevent the brush handle from causing discomfort to the hand. A rubber sheet is provided on the sponge sheet, and a number of anti-slip protrusions are provided on the rubber sheet to prevent the brush handle from slipping. Through this design, the comfort of the brush handle when held by the dentist is effectively enhanced, and the anti-slip property of the brush handle is also enhanced, which greatly improves the user experience of the dental brush and has a good use effect.
