Description

Infrared rays active electric magnet valve automatic flushing device

The utility model is a kind of health, water saving device that is used on public place and the family's supply channel.

The infrared rays active electric magnet valve automatic flushing device that adopts both at home and abroad is divided into the formula of blocking and reflective by its controller detection mode at present.The former is restricted the application scenario, and complexity is installed, and latter's controller adopts resolution element, circuit complexity, is prone to misoperation; Electromagnetic valve does not seal again, prap corrosion-vulnerable and clashing and breaking, and it is the external screw thread interface that valve body has only water inlet, and delivery port is a threadless garden pipe end, can not carry out being spirally connected of sealing with pipeline, so it the terminal of pipeline can only be connected on, the stage casing of pipeline can not be connected on.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the new infrared control electromagnetic valve that a kind of application scenario is unrestricted, easy for installation, controller circuitry is simple, antijamming capability is strong automatic flushing device is provided.

The technical solution that the utility model is taked is that infrared rays active electric magnet valve automatic flushing device is made up of controller and closed two ends external screw thread interface plastics electromagnetic valves (abbreviation electromagnetic valve), is connected by lead therebetween.Infrared processor switch, delay circuit, drive circuit, relay and the resistance that controller is made up of devices such as having infrared emission tube, receiving tube, electric capacity assembling constitute.Closed two ends external screw thread interface plastics electromagnetic valve is by valve body, be contained in electromagnet on the valve body, be contained in spool and spring in the electromagnet inner chamber, be contained in through hole lid under the spool and rubber diaphragm and valve bonnet and form, there is interface at the valve body two ends, there are two valve pockets to communicate with two interfaces respectively, two valve pockets are lived by rubber diaphragm and through hole cap seal at the top, and spool is pressed on the through hole lid flow-out hole.Six sides that one section card spanner is respectively arranged in the valve body both sides, its outer end is the external screw thread interface, valve bonnet is installed on the valve body, and the valve upper body is sealed.

That the utility model has compared to existing technology is simple in structure, easy for installation, antijamming capability is strong, is widely used.

The utility model will be described in further detail in conjunction with the accompanying drawings.

Fig. 1 is closed two ends external screw thread interface plastics electromagnetic valve structure figure.

Fig. 2 is the A-A sectional drawing among Fig. 1.

Fig. 3 is the top view of Fig. 1.

Fig. 4 is the application illustration of infrared rays active electric magnet valve automatic flushing device.

Fig. 5 is the controller electrical schematic diagram of infrared rays active electric magnet valve automatic flushing device.

In Fig. 1, load onto electromagnet with screw 10 on plastics valve body 11, the constituting of electromagnet: be wound with coil 8 on the valve upper body 4, valve upper body 4 is made of plastics, and magnetic conductor 3 and last magnetic conductor 6 are housed down in it, and upper and lower magnetic conductor all is a cylindrical shell annular shape; Valve upper body 4 also is equipped with two praps 12, and prap connects with coil 8 by lead; Top on the magnetic conduction sheet 5 is sleeved on the magnetic conductor on 6, and the bottom is plugged on valve upper body 4 and the following magnetic conductor 3.Three screws 10 of valve upper body 4 usefulness are contained in (see figure 3) on the valve body 11.Valve upper body inside is hollow.One spring 7 is housed in hollow, spring bottom is a spool 9, spool 9 is pressed on the through hole N of through hole lid 2, valve pocket E in through hole N and the valve body 11 communicates, through hole lid 2 is placed on the rubber diaphragm 1, rubber diaphragm is contained between valve upper body 4 valve bodies 11, also has a through hole H on the through hole lid 2, and this through hole is communicated with the valve pocket C in the valve body with the cavity M of valve upper body.The six side F that one section card spanner is respectively arranged in the valve body both sides, its outer end is external screw thread interface B, D, and hickey B communicates with valve pocket C, and hickey D communicates with valve pocket E, and valve bonnet 13 is installed on the valve body 11, with 4 sealings of valve upper body.

The course of work of closed two ends external screw thread interface plastics electromagnetic valve shown in Figure 1 is, when fluid enters the C chamber from hickey B, enters the M chamber through through hole H, because spool is closed through hole N, makes fluid can not enter the E chamber, and electromagnetic valve is in closed condition.When the connection power supply, work of electromagnet, spool 9 moves upward under the effect of electromagnetic force, opens through hole N, and fluid enters the E chamber, enters the hypomere pipeline through hickey D, at this moment, the state that electromagnetic valve is out.After cutting off the electricity supply, spool 9 is closed through hole N, and electromagnetic valve is in closed condition.

In Fig. 4, controller is arranged on out the below or the top of glassware for drinking water, and its window is towards the water personnel, and closed two ends external screw thread interface plastics electromagnetic valve is serially connected on the pipeline of water pipe, is connected by lead therebetween.

In Fig. 5, the infrared processor switch I C7 that controller is made up of devices such as having infrared emission tube, receiving tube, delay circuit (CIR4) IC5, (C2R7) IC6, drive circuit (R8, D1,9013) IC3, relay K 2 and resistance, electric capacity assembling constitute.Below in conjunction with Fig. 4, Fig. 5 the course of work of the present utility model is described.Working method is a batch (-type), whenever the receiving tube of infrared switch receive through obstruction reflect transmit the time, infrared switch is output signal just, electromagnetic valve is opened a period of time, closes automatically then.

In Fig. 4, the transmitting tube of infrared switch, receiving tube be all towards the water personnel, as stand out glassware for drinking water the place ahead or when stretching out one's hand to before the glassware for drinking water, receiving tube is just received through transmitting that it reflects of people.Through amplifying, relatively, give IC6 pin 5 by IC5 pin 10 output signal high level, after handling, delay circuit (C2, R7) IC6 drives 9013 triodes again by pin 6 output signal high level, drive relay K 2 work, connect power of electromagnetic valve, then electromagnetic valve is opened, and goes out the outside water outlet of glassware for drinking water, time delay at the end, relay K 2 disconnects power of electromagnetic valve, and closed electromagnetic valve goes out glassware for drinking water and stops water outlet.
