Abstract
The utility model is related to Low Voltage Electrical Apparatus, are related specifically to a kind of waterproof press-button structure.Including button 1, permanent magnet 2, shell 3, magnetic induction switch 4, shell 3 has one to recessed button cavities, and permanent magnet 2 is fixed on button 1, and button 1 and permanent magnet 2 are arranged in 3 button cavities of shell, magnetic induction switch 4 is arranged in shell 3, below 3 button cavities of shell.The beneficial effects of the utility model：Using non-contacting magnetic induction pattern, be directly interposed between button and switch using shell, make button and switch it is completely isolated come, play the role of effectively anti-gas, waterproof and dustproof, protection circuit plates.
Description
Technical field
The utility model is related to Low Voltage Electrical Apparatus, are related specifically to a kind of waterproof press-button structure.
Background technology
Currently, the low-voltage electrical apparatus waterproof press-button used in wet condition, usually contact button, mainly by button,
Shell, rubber seal, switch composition, wherein switch is arranged in shell, button is located at hull outside, shell corresponding button
Position is provided with hole, and rubber seal is fixed in hole, is interposed between the waterproof work for reaching seal isolation between button and key switch
With rubber seal has projection contacts on switch.When needing trigger switch, button press is acted via rubber seal
Protrusion be transmitted to key switch, trigger switch motion.In order to effectively transmit the action of button, the thickness of rubber seal
Degree can be also easy to produce aging breakage, cause gas outside button and liquid close by rubber than relatively thin, in the long-term use
The gap of sealing reaches at switch, makes the seal failure of waterproof press-button.
Invention content
The purpose of this utility model is to provide a kind of waterproof press-button structure.The shell button position of the structure does not have hole, presses
Button puts capable triggering into using non-contacting magnetic induction pattern is split, due to not having hole and rubber seal, button and switch complete
Kept apart by shell, effectively plays the role of waterproof and dustproof, anti-gas, protection inside electric appliance, solve in background technology
There are the problem of.
The technical solution of the utility model is：
A kind of waterproof press-button structure, including button, permanent magnet, shell, magnetic induction switch.Permanent magnet is fixed on button,
Button is arranged outside shell, and magnetic induction switch is correspondingly placed in shell, below button.
Button press, when button drives permanent magnet to run to magnetic induction switch distance of reaction, magnetic induction switch is triggered.
It is not the through-hole set by waterproof press-button on the shell.
The button and magnetic induction switch is completely isolated by shell.
The triggering of the magnetic induction switch can also be that button drives permanent magnet to leave magnetic induction switch distance of reaction
When, magnetic induction switch is triggered.
The utility model has the beneficial effects that：
A kind of waterproof press-button structure provided by the utility model triggers pattern using non-contacting magnetic, directly uses shell
Be interposed between button and switch, make button and switch it is completely isolated come, play effective waterproof and dustproof, anti-gas, in protection
The effect of portion's electric appliance.
Description of the drawings
Attached drawing 1 is the schematic diagram of existing waterproof press-button structure.
Attached drawing 2 is the assembling schematic diagram of the embodiments of the present invention.
Attached drawing 3 is the action schematic diagram of the embodiments of the present invention.
In figure：Button 1, permanent magnet 2, shell 3, magnetic induction switch 4, key switch 5.
Specific implementation mode：
The realization method of the utility model is further illustrated below in conjunction with attached drawing：
A kind of waterproof press-button structure, including button 1, permanent magnet 2, shell 3, magnetic induction switch 4, shell 3 have one to recessed
Button cavities, permanent magnet 2 is fixed on button 1, and button 1 and permanent magnet 2 are arranged in 3 button cavities of shell, and magnetic induction switch 4 is set
It sets in shell 3, below 3 button cavities of shell.
When button press 1, the drive permanent magnet 2 of button 1 runs to the induction range of magnetic induction switch 4, and magnetic induction switch 4 is
It is triggered.
Since shell 3 is interposed between button 1 and switch 4, shell 3 is closed without hole and existing waterproof press-button knot
Structure compares, and eliminates hole and rubber membrane seal, and button 1 and switch 4 are kept apart by shell completely, plays effective anti-
The effect of water, dust-proof, anti-gas, protection inside electric appliance.
The above is the utility model preferred embodiment, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations also should be regarded as the scope of protection of the utility model.
Claims (2)
