Description

Technical Field

[0001] The utility model relates to the technical field of electric toothbrushes, in particular to a bubble electric toothbrush. Background Technique

[0002] An electric toothbrush is a toothbrush that makes the brush head generate high-frequency vibration through the rapid rotation or vibration of the motor core. It can instantly decompose toothpaste into fine bubbles and deeply clean the tooth gaps. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and has a massage effect on the gingival tissue. Electric toothbrushes are widely used in urban families, and many consumers with certain consumption power prefer electric toothbrushes. However, the existing electric toothbrushes remove stains on the tooth surface by the reciprocating movement of the brush head, causing the bristles to rub on the tooth surface.

[0003] During the reciprocating movement of the brush head, the toothpaste will become diluted and swollen to fill the entire tooth cavity. The reciprocating movement of the brush head drives the swinging of the bristles. The swelling of the toothpaste fills the tooth surface, and the reciprocating movement of the bristles on the tooth surface achieves the effect of brushing teeth. If air flow bubbles are introduced during the swelling of the toothpaste and the reciprocating movement of the bristles, it will undoubtedly enhance the cleaning effect of the teeth.

[0004] In view of the above problems, the present utility model is proposed. Content of the Utility Model

[0028] As Figures 1-4 shown, a bubble electric toothbrush includes a handle 1, a brush handle 2, a bottom cover 3 and a sleeve 4. The brush handle 2 is located at the upper end of the handle 1. The lower end of the brush handle 2 is movably connected to the upper end of the handle 1. The upper end of the brush handle 2 is provided with a brush head 21. The bottom cover 3 is movably installed at the lower end of the handle 1;

[0029] A plurality of brush bristles 22 perpendicular to the brush head 21 are evenly arranged at equal intervals on the front surface of the brush head 21. Two exhaust holes 24 are symmetrically arranged up and down on the front surface of the brush head 21. Airflow can be ejected from the exhaust holes 24. The exhaust holes 24 are symmetrically located in the middle area of the brush bristles 22. In this way, the ejected airflow can make the brush bristles 22 swing. An air passage 23 communicating with each other is provided in the brush handle 2 and the brush head 21. The exhaust holes 24 communicate with the air passage 23. The airflow in the air passage 23 is ejected from the exhaust holes 24;

[0030] A pump body 13, an air outlet pipe 14 and an air inlet pipe 15 are arranged inside the handle 1. The lower end of the air outlet pipe 14 is connected to the pump body 13. The upper end of the air outlet pipe 14 is located on the upper surface of the handle 1. The upper end of the air inlet pipe 15 is connected to the pump body 13. The lower end of the air inlet pipe 15 is located on the lower surface of the handle 1. When the pump body 13 works, external air enters the inside of the handle 1;

[0031] The bottom cover 3 is provided with an air inlet hole 31, the sleeve 4 is threadedly connected to the inner wall of the air inlet hole 31, the air inlet hole 31 faces the lower end of the air inlet pipe 15, and external air enters the air inlet pipe 15 through the air inlet hole 31.

[0032] The lower surface of the pump body 13 is provided with an air inlet interface 131, the upper surface of the pump body 13 is provided with an air outlet interface 132, the lower end of the air outlet pipe 14 is connected to the air outlet interface 132, and the upper end of the air inlet pipe 15 is connected to the air inlet interface 131.

[0033] The lower end of the air duct 23 is located on the lower surface of the brush handle 2. The cross-sectional dimension of the air duct 23 gradually decreases from bottom to top. In this way, during the upward flow of the air current, the internal pressure gradually increases and the flow rate will increase. In this way, when it sprays out from the exhaust holes 24, it has a certain speed.

[0034] The bottom surface of the bottom cover 3 is provided with a concave cavity, the air inlet hole 31 is arranged on the inner bottom surface of the concave cavity, and the bottom surface of the sleeve 4 is flush with the outlet plane of the concave cavity.

[0035] The middle of the sleeve 4 is hollow and a central ring 41 is arranged at the middle position. A filter net 42 is arranged inside the central ring 41. The filter net 42 is parallel to the horizontal cross-section of the sleeve 4, and the filter net 42 plays a role in filtering the incoming gas.

[0036] Two control buttons 11 are arranged on the front surface of the handle 1, and the two control buttons 11 are aligned vertically.

[0037] A plurality of vertically arranged working indicator lights 12 are also arranged on the front surface of the handle 1.

[0038] To sum up: When the pump body 13 works, external air enters the air inlet pipe 15 through the inside of the sleeve 4 and the air inlet hole 31. The air flows upward in the air inlet pipe 15, enters the air outlet pipe 14, then enters the air duct 23, and finally sprays out from the two exhaust holes 24;

[0039] During the process of brushing teeth, the sprayed air current helps the bristles 2 to swing. On the basis that the bristles 2 reciprocate with the brush head 21, the bristles 2 can also swing up, down, left and right. In this way, the contact area and contact force between the bristles 2 and the tooth surface can be enhanced, which helps the bristles 3 to clean the stains on the tooth surface;

[0040] The sprayed air current can quickly expand the toothpaste into a foamy shape, which is beneficial for the foamy toothpaste to quickly and comprehensively cover the surfaces of all teeth. Collaborating with the reciprocating and swinging bristles 2, it can quickly and effectively clean the teeth;

[0041] When the gas passes through the sleeve 4, it can pass through the filter screen 42. The filter screen 42 can filter small particulate matter in the air, preventing the small particulate matter from clogging the intake pipe 15, the exhaust pipe 14 and the air passage 23, and making the whole toothbrush not easily damaged.

[0042] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
