Description

Technical Field

[0001] The utility model relates to the technical field of tooth care, in particular to a pull-out type dental irrigator. Background Art

[0002] Food debris stuck between teeth, besides making people uncomfortable and carrying bacteria itself, has a greater harm in that it provides nutrients for dental plaque. Dental plaque is very easy to calcify and turn into dental calculus, which accumulates at the tooth root, compresses and stimulates the periodontal environment, causing periodontal atrophy. Therefore, a dental irrigator has been developed on the market, which is a tool that uses pulsed water flow to clean teeth and tooth gaps. The water flow with appropriate pressure can effectively clean people's teeth and oral cavity.

[0003] Some existing dental irrigator heads are connected to the dental irrigator through threads to facilitate the replacement of different dental irrigator heads. However, during the use of the threaded dental irrigator head, the thread may become loose, affecting the water output of the dental irrigator head. Therefore, how to design a pull-out type dental irrigator has become a problem that needs to be solved currently. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides the following technical solutions:

[0005] A pull-out type dental irrigator includes a body. A threaded opening is provided at the top of the body, and a dental irrigation tube is threadedly connected to the inner wall of the threaded opening provided at the top of the body. A first spring is fixedly installed inside the body, and a clamping block is fixedly installed at one end of the first spring. An annular sliding groove adapted to the clamping block is provided on the outer surface of the dental irrigation tube;

[0006] A pull-out water tank is slidably connected to the outer surface of the body. A second spring is fixedly installed inside the body, and a limiting block is fixedly installed at one end of the second spring. A limiting groove adapted to the limiting block is provided inside the pull-out water tank, and a pressing block is slidably connected to the inner wall of the limiting groove provided inside the pull-out water tank.

[0007] Preferably, a rubber anti-slip pad is fixedly installed at the bottom of the pull-out water tank.

[0008] Preferably, sliding blocks are fixedly installed on opposite sides of the pressing block, and sliding grooves are provided on the inner wall of the limiting groove provided inside the pull-out water tank. The sliding blocks are adapted to the sliding grooves.

[0009] Preferably, an observation window is provided inside the pull-out water tank, and scale lines are provided on the outer side of the observation window.

[0010] Preferably, a push rod is fixedly installed at the top of the clamping block, and a long strip-shaped sliding hole is provided at the top of the body. The push rod penetrates to the outside of the long strip-shaped sliding hole.

[0011] Preferably, a sealing plug is arranged inside the drawable water tank, an elastic cord is fixedly installed on one side of the sealing plug, and one end of the elastic cord is connected to the outer surface of the drawable water tank.

[0012] Advantages of the present utility model:

[0013] First: When replacing the dental irrigator tube, the dental irrigator tube can be threadedly connected inside the body. During the installation process of the dental irrigator tube, the push block can be pushed to compress the first spring. When the annular sliding groove on the dental irrigator tube corresponds to the push block, the first spring can push the push block to be fixed with the annular sliding groove, thereby limiting the dental irrigator tube and reducing the looseness of the dental irrigator tube during use.

[0014] Second: After use, the user can push the extrusion block to move. The extrusion block can push the limiting block to compress the second spring and separate from the limiting groove, so that the drawable water tank can move upward, enabling the body to enter the drawable water tank, thereby reducing the overall length of the dental irrigator and facilitating the user to carry it when going out.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] As Figures 1 - 3 shown, the present utility model provides a technical solution:

[0021] A pull-out type dental irrigator, comprising a body 1. A threaded opening is provided at the top of the body 1. The inner wall of the threaded opening provided at the top of the body 1 is threadedly connected to a dental irrigation tube 2. A first spring 3 is fixedly installed inside the body 1. One end of the first spring 3 is fixedly installed with a clamping block 4. An annular sliding groove adapted to the clamping block 4 is provided on the outer surface of the dental irrigation tube 2. A push rod 12 is fixedly installed at the top of the clamping block 4. A long strip sliding hole is provided at the top of the body 1. The push rod 12 penetrates to the outside of the long strip sliding hole. The push rod 12 facilitates the user to push the clamping block 4 to move.

[0022] Furthermore, a pull-out water tank 5 is slidably connected to the outer surface of the body 1. A rubber anti-slip pad 9 is fixedly installed at the bottom of the pull-out water tank 5. The rubber anti-slip pad 9 can increase the anti-slip performance of the pull-out water tank 5 and facilitate the placement of the dental irrigator after use. An observation window 11 is provided inside the pull-out water tank 5. Scale lines are provided on the outer side of the observation window 11. The observation window 11 and the scale lines can facilitate the user to view the remaining amount of water inside the pull-out water tank 5 in real time. A sealing plug 13 is provided inside the pull-out water tank 5. One side of the sealing plug 13 is fixedly installed with an elastic cord 14. One end of the elastic cord 14 is connected to the outer surface of the pull-out water tank 5. When opening the sealing plug 13 to inject water into the pull-out water tank 5, the elastic cord 14 can restrain the sealing plug 13 and reduce the situation of the sealing plug 13 being lost.

[0023] Furthermore, a second spring 6 is fixedly installed inside the body 1. One end of the second spring 6 is fixedly installed with a limiting block 7. A limiting groove adapted to the limiting block 7 is provided inside the pull-out water tank 5. An extrusion block 8 is slidably connected to the inner wall of the limiting groove provided inside the pull-out water tank 5. Sliding blocks 10 are fixedly installed on both opposite sides of the extrusion block 8. A sliding groove is provided on the inner wall of the limiting groove provided inside the pull-out water tank 5. The sliding blocks 10 are adapted to the sliding groove. The sliding blocks 10 and the sliding groove can limit the moving range of the extrusion block 8 and at the same time make the extrusion block 8 move more smoothly.

[0024] The working process of the present utility model: When replacing the dental irrigation tube 2, the dental irrigation tube 2 can be threadedly connected inside the body 1. During the installation process of the dental irrigation tube 2, the clamping block 4 can be pushed to compress the first spring 3. When the annular sliding groove on the dental irrigation tube 2 corresponds to the clamping block 4, the first spring 3 can push the clamping block 4 to be fixed to the annular sliding groove, thereby limiting the dental irrigation tube 2 and reducing the loosening of the dental irrigation tube 2 during use; when it is necessary to remove the dental irrigation tube 2, only need to push the push rod 12 to move. The push rod 12 can drive the clamping block 4 to compress the first spring 3, so that the clamping block 4 is separated from the annular clamping groove, and then the dental irrigation tube 2 can be unscrewed.

[0025] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it.
