Description

A kind of dustproof device for water outlet of water dispenser

Technical field

The present invention relates to a kind of dust guard, is specifically a kind of dustproof device for water outlet of water dispenser.

Background technology

Along with the raising of people's living standard, city dweller progressively changes drinking pure water into from original boiling water with running water voluntarily, and water dispenser enters the family of ordinary people as a kind of novel home appliance.Existing water dispenser, all with the mode water outlet of tap, outside its delivery port is chronically exposed to, fills the air above aerial dust and bacterium be easy to stick to, thus causes secondary pollution to the water of releasing, constitute a latent danger to the health of people.Solution conventional at present has two kinds, and one is periodic cleaning, because the smaller cleaning up of spout member compares effort.So there has been the second solution, exactly dust-proof cover for drinker (patent CN201119775Y Qian Peidong) is set at water outlet.But dust cover needs manual folding, operate comparatively loaded down with trivial details in actual use, and the closedown of dust cover also have difficulties, so be restricted in actual applications when both hands all hold water tumbler time.

Summary of the invention

The object of the invention is to, be exposed to outer easily contaminated and existing dirt-proof boot for current water outlet of drinking machine and cannot apply inconvenient practical problem by automatic open-close, a kind of delivery port dust guard with automatic open-close ability is provided.

The object of the present invention is achieved like this: provide a kind of dustproof device for water outlet of water dispenser, the dust-proof slide plate control system comprising dust cover, dust-proof slide plate and be made up of iron core, spring, controller; Controller comprises optocoupler, single-chip microcomputer, driving chip, relay and o; One end of dust-proof slide plate is directly connected with iron core, and the other end is connected with dust cover by spring, and iron core and o connect; Controller opens startup by switch of water dispenser, and signal is delivered to single-chip microcomputer by optocoupler, and is opened by driving chip control relay, and then makes solenoid, controls iron core to a lateral movement, and iron core drives whole dust-proof slide plate to remove; Controller is by the closed cut out of switch of water dispenser, signal is delivered to single-chip microcomputer by optocoupler, and within 3 ~ 5 seconds, closed by the time delay of driving chip control relay, and then make o power-off, o disappears to the control action of iron core, and the effect that dust-proof slide plate is subject to other end spring is returned to home position.

In actual applications, this dustproof device for water outlet of water dispenser is work like this:

First, when switch of water dispenser is opened time, optocoupler perceives signal and this signal is sent to single-chip microcomputer, single-chip microcomputer to obtain this signal transmission after signal to driving chip, and control relay is started working, thus make o pull iron core toward a lateral movement, force the dust-proof slide plate with iron core is fixing also to be followed together to a lateral movement, originally, after the dust-proof slide plate blocking outlet pipe is removed, water just to flow out from water pipe.Meanwhile, due to the movement of dust-proof slide plate, the spring be connected with the dust-proof slide plate other end is elongated.After water has connect, switch of water dispenser has disconnected, and optocoupler passes to single-chip microcomputer this information, single-chip microcomputer again by signal transmission to driving chip, driving chip cuts off the circuit of o and discharging device by relay.Because o loses magnetic field, so iron core disappears to the pulling force of dust-proof slide plate, dust-proof slide plate restores to the original state because of the restoring force of the spring be opened, and has again blocked water pipe.

In sum, the invention has the beneficial effects as follows apparent.Owing to having set up a dust guard at water outlet, so effectively can prevent from filling the air aerial dust and bacterial adsorption on delivery port, ensured the clean hygiene of delivery port, stopped to pollute the second time of pure water, guarantee is drunk water the health of people.Simultaneously, owing to have employed the dust-proof slide plate control system be made up of iron core, spring, controller, specifically by the dust-proof slide plate control system of optocoupler, single-chip microcomputer, driving chip, relay and o composition control device, thus ensure that the dust-proof slide plate in this dust guard can slide automatically according to the folding of switch of water dispenser.Due to the folding not needing people's manual operation just can complete whole protective cover, make in the middle of practical application convenient, health.

Component of the present invention comprises 1-dust cover, 2-spring, 3-water pipe, the dust-proof slide plate of 4-, 5-iron core, 6-o, 7-relay, 8-driving chip, 9-single-chip microcomputer, 10-optocoupler, 11-switch of water dispenser.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is further explained

Embodiment

When not using, whole device as shown in Figure 2, forms a closed protective cover, effectively prevents from filling the air aerial dust and bacterial adsorption on delivery port.When needs are drunk water, switch of water dispenser 11 is opened as shown in Figure 4, and optocoupler 10 perceives signal and this signal is sent to single-chip microcomputer 9, and single-chip microcomputer 9 to obtain this signal transmission after signal to driving chip 8, and control relay 7 is started working, thus o 6 is made to produce magnetic field.As shown in Figure 1, the magnetic field that o 6 produces pulls iron core 5 toward a lateral movement, and iron core 5 motion forces dust-proof slide plate 4 also and then together to a lateral movement, and the dust-proof slide plate 4 originally blocking outlet pipe 3 is removed, as shown in Figure 3, water just to flow out from water pipe 3.Meanwhile, due to the movement of dust-proof slide plate 4, the spring 2 in Fig. 1 is elongated.There is deformation.After water has connect, switch of water dispenser disconnect, optocoupler 10 passes to single-chip microcomputer 9 this information, single-chip microcomputer 9 again by signal transmission to driving chip 8, driving chip 8 cuts off the circuit of o 6 and discharging device by relay 7.Because o 6 loses magnetic field, so disappear to the pulling force of iron core 5, and then disappear to the pulling force of dust-proof slide plate 4, dust-proof slide plate 4 restores to the original state because of the restoring force that the spring 2 of deformation occurs, and has again blocked water pipe 3.

In the middle of this process, the speed removed due to dust-proof slide plate 4 is very fast, so do not have water before removing from water pipe 3 out.When water has connect, when switch of water dispenser 11 disconnects, because the circuitry cuts of o 6 is than discharging device circuit delay 3 ~ 5 second, thus the water droplet do not dripped off in anti-antipriming pipe is on dust-proof slide plate 4, ensures the cleaning of the especially dust-proof slide plate 4 of whole dust guard.
