Description

Electric toothbrush waterproof construction

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the toothbrush field, concretely relates to electric toothbrush waterproof construction.

[ background of the invention ]

The electric toothbrush is a toothbrush invented by Philippe-Guy Woog, the brush head generates high-frequency vibration through the extremely-fast rotation or vibration of the motor core, toothpaste is instantly decomposed into fine foam to deeply clean slits between teeth, and meanwhile, the vibration of the bristles can promote the blood circulation in the oral cavity and has a massage effect on gum tissues.

The electric toothbrush motor is located inside the toothbrush handle, and the outside fixed brush head is stretched out to the transmission shaft, in order to place inside waterproof sealing's of water entering brush holder processing of carrying out usually, has now to add waterproof circle and axle sleeve in brush holder front end outside, drops easily under high-frequency vibration, causes waterproof inefficacy, and the reliability is poor and use inconveniently.

[ Utility model ] content

In order to solve the existing problem that exists among the background art, the utility model provides a charging case.

The utility model adopts the following technical proposal:

a waterproof structure of an electric toothbrush, which is located at the front end of a brush handle, comprises:

the shaft sleeve is embedded and attached to the interior of the containing groove which is designed in a concave manner at the front end of the brush handle;

the waterproof ring is arranged on the shaft sleeve, and the end face of the waterproof ring is flush with the front end face of the brush handle and is matched with and seals the accommodating groove;

the transmission shaft inside the brush handle penetrates through the shaft sleeve in a matching mode and extends out of the brush handle.

Furthermore, the axle sleeve is the silica gel axle sleeve.

Furthermore, the waterproof ring is a silica gel waterproof ring.

Furthermore, an outward convex circular rib position is arranged on the large end face of the shaft sleeve, an annular groove is formed in one face opposite to the rib position, the front end of the shaft sleeve is an extending portion, and a protruding portion is arranged in the extending portion and just covers the outer edge face of the transmission shaft.

Furthermore, the bottom of the accommodating groove is provided with a fixing groove matched with the rib position, and the shaft sleeve is just attached to the bottom surface of the accommodating groove.

Furthermore, the waterproof ring is detachably arranged in the annular groove and is hermetically connected with the outer part of the shaft sleeve.

The utility model has the advantages as follows:

the utility model discloses with waterproof construction setting in the inside of brush holder front end, its middle shaft cover and waterproof circle all adopt silica gel to make, the axle sleeve inlays to be established inside the brush holder front end, waterproof circle and axle sleeve form sealed waterproof construction, can not cause to drop and influence the use because of the vibration when the toothbrush uses, promote the reliability.

[ description of the drawings ]

FIG. 1 is an exploded view of the waterproof structure of the electric toothbrush of the present invention;

FIG. 2 is a schematic view of the structure of the brush handle of the present invention;

fig. 3 is an assembly schematic diagram of the waterproof structure of the present invention.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

As shown in fig. 1-3:

the utility model particularly relates to an electric toothbrush waterproof construction, it is different from the outside of current waterproof construction setting at the brush holder front end, the utility model discloses a waterproof construction sets up inside 1 front ends of brush holders, and concrete structure is including axle sleeve 2 and waterproof circle 3.

Referring to fig. 2, first, an indent receiving groove 4 is formed in the front end of the brush handle 1 for tightly receiving the shaft sleeve 2 and the waterproof ring 3, and a fixing groove 41 is formed at the bottom of the receiving groove 4, wherein the fixing groove 41 has a circular track and a rectangular cross section.

The axle sleeve 2 selects to be the silica gel axle sleeve, the silica gel axle sleeve has elasticity and the characteristic of deformation, be well logical structure in the middle of the axle sleeve 2, as shown in fig. 3, and be equipped with the circular muscle position 21 of evagination on the big terminal surface, set up ring channel 22 in the one side that is carried on the back the muscle position, during the equipment, 2 big terminal surfaces of axle sleeve are packed into towards fixed slot 41, guarantee that muscle position 21 is in the chucking fixed slot 41 just, and big terminal surface laminating in storage tank 4 terminal surface, in addition, axle sleeve 2 outer periphery has the sand grip, make things convenient for axle sleeve 2 to pack into and take out, simultaneously, the inside bulge 24 that establishes of the extension 23 at axle sleeve 2 front end, when packing into, the sunken part that the bulge 24 was established just withstoo.

Then, as figure 1, this waterproof circle 3 also selects the waterproof circle of silica gel, waterproof circle 3 is the same detachable dress and becomes sealed integrative with the ring channel 22 on the axle sleeve 2, the back of packing into, flush on waterproof circle 3's the terminal surface and the brush holder 1 preceding terminal surface and seal storage tank 4 and play waterproof function, all design waterproof circle 3 and axle sleeve 2 and carry out the installation back of fastening in the inside of brush holder 1, can not drop easily because of vibrations when brushing teeth, improve the use reliability, carry out effectual water proof protection to motor and internal circuit, and service life is prolonged.

The utility model has the advantages that:

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
