Embodiment

[0015] When the entire device is not in use as figure 2 As shown, a closed protective cover is formed to effectively prevent the dust and bacteria in the air from being adsorbed on the water outlet. When drinking water is required, such as Figure 4 The shown water dispenser switch 11 is turned on, the optocoupler 10 perceives the signal and sends the signal to the single-chip microcomputer 9, and the single-chip microcomputer 9 transmits the signal to the driver chip 8 after receiving the signal, and controls the relay 7 to start working, so that the electromagnetic helix Tube 6 generates a magnetic field. Such as figure 1 As shown, the magnetic field generated by the electromagnetic solenoid 6 pulls the iron core 5 to move to one side, and the movement of the iron core 5 forces the dust-proof slide 4 to move to one side together, so that the dust-proof slide 4 that originally blocked the water outlet pipe 3 move away, such as image 3 Shown, water has just flowed out fr...

Abstract

The invention provides a dustproof device for a water outlet of a water dispenser. The dustproof device comprises a dustproof shell, a dustproof slip sheet and a dustproof slip sheet control system, wherein the dustproof slip sheet control system consists of an iron core, a spring and a controller; the controller comprises an optical coupler, a singlechip, a driving chip, a relay and an electromagnetic solenoid; one end of the dustproof slip sheet is directly connected with the iron core, the other end of the dustproof slip sheet is connected with the dustproof shell through the spring, and the iron core is connected with the electromagnetic solenoid; and the controller is controlled by a water dispenser switch. The dustproof device can effectively prevent dust and bacteria in the air from being adsorbed on the water outlet and ensure cleanness and sanitation of the water outlet; and because the dustproof slip sheet in the dustproof device can automatically slip according to on and off of the water dispenser switch, the dustproof device is more convenient and sanitary in practical application.

Description

technical field [0001] The invention relates to a dustproof device, in particular to a dustproof device for a water outlet of a water dispenser. Background technique [0002] With the improvement of people's living standards, urban residents have gradually changed from boiling water with tap water to drinking pure water. Water dispensers have entered the families of ordinary people as a new type of household electrical appliance. Existing water dispensers all discharge water in the form of a faucet. The water outlet is exposed to the outside for a long time, and the dust and bacteria permeating the air are easy to adhere to it, thereby causing secondary pollution to the released water and posing a hidden danger to human health. . There are two commonly used solutions at present, one is regular cleaning, because the water outlet components are relatively small and it is more laborious to clean. So there is a second solution, which is to set the water dispenser dust cover at...
