[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0023] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] refer to Figure 1-6 Now, the efficient cleaning ultrasonic toothbrush provided by the embodiment of the utility model is described. The efficient cleaning ultrasonic toothbrush comprises an electric toothbrush body 1, the output end of the electric toothbrush body 1 is fixedly connected to a transmission rod 12, a connecting tube 3 is slidably connected to the circumferential surface of the upper end of the electric toothbrush body 1, a brush head 2 is rotatably connected inside the connecting tube 3, a plug-in slot 11 is provided on the lower end surface of the brush head 2, and the plug-in slot 11 is movably connected to the transmission rod 12; a cavity 5 is arranged inside the upper end of the electric toothbrush body 1, and a limiting component 4 is arranged inside the cavity 5.

[0026] Specifically, the insertion slot 11 of the brush head 2 is first matched with the transmission rod 12, so as to facilitate the connection tube 3 to be sleeved on the upper end of the electric toothbrush body 1. After the connection tube 3 is sleeved on the upper end of the electric toothbrush body 1, the connection tube 3 can be limited with the cooperation of the limiting component 4, so as to prevent the connection tube 3 from being separated from the electric toothbrush body 1, and then prevent the brush head 2 from being separated from the electric toothbrush body 1, so that the brush head 2 can work stably, which is conducive to improving the experience.

[0027] The limiting assembly 4 includes a limiting rod 401, an auxiliary rod 402 and a spring 403. The limiting rod 401 and the auxiliary rod 402 are slidably connected inside the cavity 5. The lower end of the limiting rod 401 is fixedly connected to the auxiliary rod 402. The spring 403 is fixedly connected between the limiting rod 401 and the inner wall of the cavity 5. A limiting hole 6 is opened on the circumferential surface of the connecting cylinder 3. The limiting hole 6 cooperates with the limiting rod 401. When working, when the connecting cylinder 3 contacts the limiting rod 401, it will squeeze the limiting rod 401 to shrink into the cavity 5, and at the same time The spring 403 is compressed. As the connecting tube 3 moves downward, when the limiting hole 6 of the connecting tube 3 corresponds to the limiting rod 401, the limiting rod 401 can be driven to be stuck into the limiting hole 6 under the action of the compression spring 403, thereby realizing the limitation of the connecting tube 3; when the brush head 2 needs to be replaced, the limiting rod 401 is driven to disengage from the limiting hole 6 by pressing the auxiliary rod 402, thereby releasing the limitation on the connecting tube 3, and then it is convenient to remove the brush head 2 from the electric toothbrush body 1, so as to facilitate the replacement of the new brush head 2.

[0028] The limiting rod 401 is in an L-shape, and an end of the limiting rod 401 close to the limiting hole 6 is provided with an upwardly inclined surface, which facilitates squeezing the limiting rod 401 into the cavity 5 during operation.

[0029] An annular groove 7 is provided on the inner wall of the connecting tube 3, and a limiting ring 8 is slidably connected inside the annular groove 7. The limiting ring 8 is fixedly connected to the brush head 2, which can prevent the brush head 2 from detaching from the connecting tube 3 during operation, thereby enhancing the stability of the connection between the brush head 2 and the connecting tube 3.

[0030] A limiting groove 9 is provided on the inner wall of the connecting tube 3, and a limiting strip 10 is slidably connected inside the limiting groove 9. The limiting strip 10 is fixedly connected to the electric toothbrush body 1, and the installation position of the connecting tube 3 can be limited during operation, which is conducive to the cooperation between the limiting rod 401 and the limiting hole 6.

[0031] The end surface shapes of the transmission rod 12 and the end surface shapes of the insertion slot 11 are both hexagonal, which is convenient for driving the brush head 2 to work.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
