Description

Technical Field

[0001] The utility model relates to the technical field of oral cleaning, in particular to an interdental brush with a replaceable brush head. Background Art

[0002] Interdental brushes are similar to ordinary toothbrushes, with a brush head and a handle. The biggest difference is the design of the brush head. The brush head of an interdental brush is cone-shaped and has different sizes. It is suitable for different widths of interdental gaps. You can choose different specifications of brush heads to clean the gaps and tooth surfaces according to your needs. The handle of an interdental brush has different lengths. When the handle of the interdental brush is not damaged, you only need to replace the brush head regularly, which is very convenient and affordable.

[0003] An interdental brush described in publication number CN219614078U includes a toothbrush handle, a brush head and a fixing part. A fastener is provided on the toothbrush handle, and the end of the brush head can extend into the fastener. The fixing part is detachably connected to the fastener, and the fixing part can exert a force on the fastener so that the fastener clamps the brush head. When the brush head of the interdental brush is damaged, the user only needs to replace the brush head, and the use cost is low.

[0004] Although the above interdental brush solves certain problems, it still has the following disadvantages:

[0005] When replacing the brush head, you need to first unscrew the nut from the toothbrush handle, remove the brush head and then tighten the nut again. If the nut is not tightened enough, the brush head may fall off, making it more troublesome to replace. Utility Model Content

DETAILED DESCRIPTION

[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] 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. 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.

[0039] Embodiment 1:

[0040] like Figures 1 to 10 As shown, this embodiment provides an interdental brush with a replaceable brush head, including a brush handle 1, a mounting block 2, an insert block 3, a brush head 4, a sleeve 5, a clamping tube 6, a control assembly 7 and two positioning blocks 8 arranged at the front end of the sleeve 5.

[0041] Among them, the upper end of the brush handle 1 is connected to a mounting block 2, a circular mounting groove 201 is provided at the upper end of the front side of the mounting block 2, a plug block 3 with a conical front end is inserted into the mounting groove 201, the plug block 3 is fixed to the front side of the mounting block 2 through the mounting groove 201, a movable groove 301 is provided at the rear end of the plug block 3, a card slot 302 is provided on the front side of the movable groove 301, a socket 303 is provided on the front side of the card slot 302, the entire plug block 3 passes through the movable groove 301, the card slot 302 and the socket 303 from front to back, and the diameters of the movable groove 301, the card slot 302 and the socket 303 are smaller and smaller in sequence, and the rear end of the brush head 4 is inserted into the plug block 3 through the inside of the socket 303.

[0042] A sleeve 5 is inserted into the slot 302 inside the insert block 3, and the outer rear end of the sleeve 5 is connected to the retaining ring 501. The retaining ring 501 is stuck in the front end of the movable slot 301, and a clamping tube 6 with a chamfered front end is inserted into the sleeve 5. Deformation slots 601 are provided on the front halves of both sides of the clamping tube 6, so that the upper and lower parts of the front half of the clamping tube 6 can be deformed, and the internal aperture can be changed in size. After the rear end of the brush head 4 is inserted into the clamping tube 6, the clamping tube 6 moves backward, and the sleeve 5 tightens the front half of the clamping tube 6 to reduce the aperture of a section of the deformation slot 601 in the front half of the clamping tube 6, thereby clamping the rear end of the brush head 4, thereby realizing the function of clamping the brush head 4.

[0043] In order to facilitate the operation of moving the clamping cylinder 6 forward and backward, a control component 7 is set between the clamping cylinder 6 and the mounting block 2, and the control component 7 includes a button 701, a connecting hole 702 and a spring 703 in a compressed state. The rear end of the clamping cylinder 6 is connected to a circular baffle 602, which is inside the movable groove 301 and against the rear side of the mounting groove 201. There is a spring 703 between the baffle 602 and the baffle ring 501 and is sleeved on the outside of the clamping cylinder 6. The spring 703 pushes the baffle ring 501 against the front end of the movable groove 301 and the baffle 602 against the rear end of the mounting groove 201. A button 701 is installed at the rear end of the baffle 602. The rear end of the button 701 extends from the inside of the connecting hole 702 opened on the rear side of the mounting block 2 to the rear side of the outside of the mounting block 2. The rear end of the button 701 is rounded to avoid scratching the oral cavity during use.

[0044] By pressing the button 701, the clamping tube 6 can be pushed forward, and the clamping tube 6 with the deformation slot 601 is not restricted by the clamping of the sleeve 5, and the rear end of the brush head 4 can be inserted into the interior of the clamping tube 6. When the pressure on the button 701 is removed, the compressed spring 703 will automatically rebound the baffle 602 backward, and the baffle 602 moves backward with the clamping tube 6. The sleeve 5 "closes" the front end of the clamping tube 6 and clamps the rear end of the brush head 4, thereby realizing the function of pressing the button 701, removing the old brush head, replacing it with a new brush head, and then releasing the button 701 to automatically clamp the brush head.

[0045] Embodiment 2:

[0046] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0047] Positioning blocks 8 are installed on both sides of the front end of the sleeve 5. The ends of the positioning blocks 8 that are close to each other slightly block the opening of the front end of the sleeve 5, and the rear end of the part that blocks the opening is chamfered. In this way, the positioning blocks 8 are aligned with the deformation slot 601. When the clamping tube 6 moves forward, the positioning blocks 8 can assist the clamping tube 6 to open the front half of the deformation slot 601 to separate the upper and lower parts, so that the rear end of the brush head 4 is easier to insert into the interior of the clamping tube 6, thereby realizing the function of separating the front end of the clamping tube 6 from top to bottom.

[0048] Embodiment 3:

[0049] The solution in Example 2 is further introduced below in combination with a specific working method, as described below:

[0050] A plurality of evenly distributed anti-skid grooves 9 are provided in the front half of the interior of the clamping tube 6 to increase the friction between the interior of the clamping tube 6 and the exterior of the brush head 4 so that the brush head 4 can be clamped more firmly.

[0051] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
