Technical Field
[0001] The utility model relates to the technical field of toothbrush manufacturing, in particular to a waterproof mechanism for an electric toothbrush base. Background Technique
[0002] With the progress of modern life, more and more people attach great importance to dental health. Therefore, most people will choose an electric toothbrush to clean their teeth. An electric toothbrush generally consists of two parts, a charging stand and a toothbrush body. Generally, the charging stand and the toothbrush body are movably plugged together. Therefore, the charging stand generally also has a certain storage capacity.
[0003] When the charging stand is actually used, it is usually placed beside the washbasin for the convenience of the user to charge after use. However, since the washbasin is usually used for face washing and cleaning operations, water stains are likely to splash beside most washbasins. Therefore, the charging stand generally has a certain waterproof ability. However, the charging connection port of most charging stands is always exposed on the surface of the air, making it possible for the charging connection port to be eroded by water droplets, which easily oxidizes the surface of the connecting rod, and further reduces the service life of the electric toothbrush when in use.
[0004] In view of the above situation, we propose a waterproof mechanism for an electric toothbrush base. Content of the Utility Model
[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a waterproof mechanism for an electric toothbrush base.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A waterproof mechanism for an electric toothbrush base, including a toothbrush main body and a brush handle movably plugged above the toothbrush main body. The top of the brush handle is fixedly connected with a toothbrush head. The bottom of the toothbrush main body is provided with a base for positioning the toothbrush main body. The inside of the base is provided with a rebound waterproof mechanism for preventing water from entering the inside of the base. The rebound waterproof mechanism includes:
[0008] A waterproof board, which is slidably connected inside the base, and a waterproof gasket is wrapped around the outside of the waterproof board;
[0009] An upper splicing board, with a lower splicing board arranged below the upper splicing board. The bottoms of the upper splicing board and the lower splicing board are fixedly connected to the outer surface of the waterproof board;
[0010] A spring, the top of which is fixedly connected to the bottom of the waterproof board, and the bottom of the spring is fixedly connected to the inner wall of the base.
[0011] Preferably, a clamping platform is fixedly connected to the top of the waterproof plate, and the clamping platform is used to increase the contact area with the toothbrush body.
[0012] Preferably, a positive magnetic attraction plate is fixedly connected to the bottom of the waterproof plate, a negative magnetic attraction plate is arranged directly below the positive magnetic attraction plate, and the bottom of the negative magnetic attraction plate is fixedly connected to the outer surface of the base.
[0013] Preferably, an electric connecting rod is arranged inside the negative magnetic attraction plate, and the bottom of the electric connecting rod is electrically connected to the internal structure of the base.
[0014] Preferably, the electric connecting rod is movably clamped to the bottom of the toothbrush body, a switch is arranged on the outer surface of the toothbrush body, and the electric connecting rod is arranged directly below the upper splicing plate and the lower splicing plate.
[0015] The present utility model discloses a waterproof mechanism for an electric toothbrush base, and the beneficial effects thereof are as follows:
[0016] For the waterproof mechanism of the electric toothbrush base, when the user stores and charges the toothbrush, the user first places the toothbrush downwardly against the base, so that the waterproof plate is pressed downwardly. During the downward pressing process, the top of the electric connecting rod will pass through between the upper splicing plate and the lower splicing plate, so that the electric connecting rod is connected to the toothbrush body. At the same time, the positive magnetic attraction plate and the negative magnetic attraction plate are attracted and connected, which can make the connection between the electric connecting rod and the toothbrush body tighter. When the charging is completed, the toothbrush body is picked up, so that the spring rebounds to drive the waterproof plate to rise. When the waterproof plate rises, the upper splicing plate and the lower splicing plate inside the waterproof plate will slide upwardly accordingly. At the same time, the upper splicing plate and the lower splicing plate are made of soft silicone. When leaving the electric connecting rod, they will be spliced and connected again, so that the electric connecting rod is in a relatively sealed space, preventing water from entering the inside of the base, and thus reducing the probability of water ingress and damage to the base.
