Damage.
Utility model content
The purpose of this utility model is to provide a kind of waterproof construction of electric toothbrush, and its is simple in construction, firm, water resistance
Good, security performance is high, service life length.
The utility model can be achieved through the following technical solutions：
The utility model discloses a kind of waterproof construction of electric toothbrush, including handle cylinder, the interior motor placed of handle cylinder
Component, electric machine assembly are provided with rotating shaft bar, and described rotating shaft bar one end is connected with brush, it is characterised in that：The electric toothbrush is prevented
Water-bound is double layer water-proof structure, and the inside on the handle cylinder top is provided with the projection of rotating shaft bar, the handle cylinder top
Projection and rotating shaft bar between be provided with the first water proof ring, the second waterproof layer is provided with below first water proof ring, described second prevents
Water layer is arranged between rotating shaft bar, electric machine assembly and handle cylinder.This electric toothbrush is provided with two layers of waterproof layer so that water resistance
Greatly promote；First water proof ring is arranged between internal protrusion and the rotating shaft bar on handle cylinder top, such waterproof construction
Setting is very firm, is less prone to and the phenomenon that water infilters its interior is produced because of structural stability difference；Second waterproof layer
Between rotating shaft bar, electric machine assembly and handle cylinder, further prevent from seeping water；Because the setting of this waterproof construction is very
Firm and good seal performance, so the security performance of electric toothbrush is high, service life length.
Further, groove is provided with outside first water proof ring, utilizes the groove outside the first water proof ring and handle cylinder
The raised engaging on top, allows the first water proof ring to be more firmly installed between handle cylinder and rotating shaft bar, makes electric toothbrush
Waterproof construction it is more firm, water resistance is more excellent.
Preferably, the groove is distributed in the first water proof ring space outside, and such structure setting causes the first water proof ring
It is more firm with the engaging of handle cylinder so that the water resistance of whole waterproof construction greatly improves.
Preferably, the groove forms a circumference outside the first water proof ring, and such structure setting make it that first is anti-
Hydrosphere increases with the engaging area of handle cylinder so that engaging is more firm, and whole waterproof construction is also more firm, so that can also
Improve the water resistance of total.
Further, the shape of the handle cylinder upper lobes is corresponding with the first water proof ring exterior groove shape, such
Structure setting so that the groove of the first water proof ring engages completely with the projection on handle cylinder top so that whole waterproof construction is more
Stable, the water resistance of whole electric toothbrush greatly improves.
Further, first water proof ring by be interference fitted installed in handle cylinder top projection with rotating shaft bar it
Between, such fit system causes waterproof layer to be fitted close with handle cylinder, rotating shaft bar so that the water resistance of electric toothbrush is more
It is good.
Further, the umbrella that second waterproof layer stands upside down into circle, the second waterproof layer are arranged on by interference fit
Between rotating shaft bar, electric machine assembly and handle cylinder, the second waterproof layer is set below the first water proof ring, strengthens the waterproof of electric toothbrush
Function；Second waterproof layer is installed by the way of interference fit, the sealing effectiveness of structure can be improved, is that waterproof effect is more preferable；
Second waterproof layer is arranged to the umbrella of circular handstand, infiltration phenomenon is generated because usage time is long even in toothbrush,
Certain cushioning effect can be played by the umbrella of this handstand, extend the service life of electric toothbrush.
Further, first water proof ring and the second waterproof layer are flexible material, such material selection, not only may be used
To improve the installation capability of waterproof layer so that interference fit is easier to realize, more preferable to improve the anti-of electric toothbrush waterproof construction
Water-based energy, and the sealing property of waterproof construction can be improved.
A kind of the utility model handset mounting hot melt rubber stick processing unit (plant), there is following beneficial effect：
Firstth, waterproof construction consolidates, and this waterproof construction sets double-deck anti-using the first water proof ring and the second waterproof layer
Shield, and the waterproof layer is made of flexible material, first water proof ring is matched somebody with somebody using groove with the raised interference on handle cylinder
Engaging is closed, is interference fitted between second waterproof layer and electric machine assembly, rotating shaft bar, handle cylinder, the fixation of this two layers of waterproof layer
Mode is all very firmly, so the waterproof construction of whole electric toothbrush is all very firm.
Secondth, water resistance is fine, this waterproof construction set using this waterproof construction using the first water proof ring and
Second waterproof layer Double-protection so that water resistance greatly improves；First water proof ring and the second waterproof layer all use interference
The mode of cooperation is fixed so that the sealing property of waterproof construction is fine, so water resistance also greatly improves；Described second
Waterproof layer is provided in round the umbrella stood upside down, and infiltration phenomenon occurs because usage time is long even in electric toothbrush, so
The umbrella-shaped structure of handstand can also play certain cushioning effect.
3rd, security performance is high, because the water resistance of this electric toothbrush is fine, is less prone to infiltration phenomenon,
So security performance greatly improves.
4th, service life is grown, because the water resistance of this electric toothbrush is fine, its security performance is also very high,
So its service life is very long, because the second waterproof layer is provided in round the umbrella stood upside down, even if electric toothbrush service life mistake
Grow and cause electric toothbrush infiltration phenomenon occur, as certain cushioning effect is played in the setting of the second waterproof layer, extend
The service life of electric toothbrush.
