Description

Electric toothbrush inner plug type switch key

Technical Field

The utility model relates to an electric toothbrush technical field, more specifically relates to electric toothbrush switch button structure field.

Background

Electric toothbrushes are new products that have emerged in recent years. The investigation shows that the electric toothbrush is more scientific and effective than the common toothbrush; the electric toothbrush can more thoroughly remove dental plaque and reduce gingivitis and gingival bleeding, is also a popular daily article in many countries in Europe and America at present, and the electric toothbrush drives the metal shaft to rapidly vibrate through the vibrating motor, so that the toothbrush head generates high-frequency vibration, toothpaste is instantly decomposed into fine foam, and the fine foam deeply cleans teeth; at the same time, the vibration of the bristles promotes blood circulation in the oral cavity, resulting in an unexpected massaging effect on the gum tissue.

The electric toothbrush comprises a handle, wherein a press-type switch key is arranged on the handle, and the switch key is pressed to control the on/off gear switching and other operations of the electric toothbrush; the electric toothbrush is easy to contact with water in the using process, so that the requirement on the waterproof property of the switch button is high in practical use. During present traditional way, directly mould plastics above-mentioned switch button on toothbrush handle through materials such as plastics, however above-mentioned process is more loaded down with trivial details, is unfavorable for the improvement of efficiency and the reduction of cost to, the switch button operation that the secondary was moulded plastics and is obtained feels not good. Further, although the sealing performance of the switch knob may be improved by a process using a gasket, the above structure is disadvantageous for reducing the installation space.

For the foregoing reasons, there is a need for improvements in the prior art.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide an electric toothbrush inner plug type switch key.

The utility model discloses a realize through following technical scheme: the utility model provides an electric toothbrush internal plug formula switch button, includes the handle main part be provided with the button hole in the handle main part be provided with switch button on the button hole, switch button includes the roof and connects the round lateral wall of roof one side, the roof periphery is provided with the round turn-ups the outside protrusion in lateral wall middle part forms the sealing washer the afterbody shaping of lateral wall has the round locking ring, and the lateral wall of handle main part is located the turn-ups with between the locking ring.

In the technical scheme, the switch key is made of LDPE or POM.

In the above technical scheme, the slope of the locking ring at the side close to the tail part of the locking ring is smaller than the slope of the slope at the side far away from the tail part of the locking ring.

In the technical scheme, the top wall of the switch key is an arc surface, and the end face of the turned edge is an arc surface.

In the technical scheme, the middle part of the top wall is formed with the pressing piece, and the pressing piece is positioned in the lantern ring surrounded by the side wall.

In the technical scheme, the middle part of the top wall is provided with an inward concave groove.

The utility model discloses following beneficial effect has: the utility model discloses switch button has saved the process and the product space that other electric toothbrush adopted the sealing washer, perhaps utilizes the secondary to mould plastics and realizes the loaded down with trivial details technology of sealed reassembling button, practices thrift the cost. The structure is simple to assemble, and the control hand feeling of the switch key is extremely good.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 3, the electric toothbrush inner plug type switch key comprises a handle body 1, a key hole is formed in the handle body 1, a switch key 2 is arranged on the key hole, the switch key 2 comprises a top wall 20 and a circle of side wall 21 connected to one side of the top wall, a circle of flanging 3 is arranged on the periphery of the top wall 20, a sealing ring 4 is formed in the middle of the side wall 21 in a protruding mode, a circle of locking ring 5 is formed at the tail portion of the side wall, and the side wall of the handle body is located between the flanging and the locking ring. The switch key is made of plastic (such as LDPE or POM) with toughness and ductility through injection molding, and the handle body 1 is made of a material (such as plastic and other metals) with rigidity higher than that of the switch key.

In the structure, through the injection molding material and the structure, in the process of assembling the handle main body and the switch key, the rigidity of the handle main body is stronger than that of the switch key, so that the switch key is forced to be compressed and deformed, and the trend sealing ring is tightly attached to the main body matching surface due to the reaction force of the structure and the material of the switch key, so that the sealing and waterproof effects are realized. In a similar way, the locking ring is attached to the matching surface of the handle body, so that the fastening effect is realized.

The slope of the locking ring 5 close to the tail part side is smaller than that of the slope far away from the tail part side, so that the switch key 2 can be pressed in along the key hole, and the position in the key hole is limited and is not easy to fall off.

The top wall of the switch key 2 is set to be an arc surface, and the end face of the flanging 3 is set to be an arc surface, so that the hand feeling of a user when the user presses the switch key is improved. The middle part shaping of roof 20 has a pressing member 200, pressing member 200 is located the lantern ring that the lateral wall encloses, and when using, through above-mentioned pressing member 200 and the inside main control board (current structure, not repeated herein) cooperation that sets up of handle, the realization is to the control of electric toothbrush, because pressing member 200 is set up in being located the lantern ring that the lateral wall encloses, has guaranteed that electric toothbrush can not unexpected open under the condition that is dabbed pressing member 200. The middle part of the top wall is provided with an inwardly recessed groove 201 for positioning the switch button 2.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The foregoing embodiments and description of the invention have been provided in the present application for the purpose of illustrating the principles of the invention and is subject to various changes and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be within the scope of the claimed invention.
