Description

Infrared rays passive electromagnetic 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.

What adopt both at home and abroad at present is infrared rays active electric magnet valve automatic flushing device, is divided into the formula of blocking and reflective by its controller detection mode.The former is restricted the application scenario, and complexity is installed, and latter's controller circuitry 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 provide that a kind of application scenario is unrestricted, easy for installation, controller circuitry is simple, resist in the strong new infrared control electromagnetic valve automatic flushing device of the ability of disturbing.

The technical solution that the utility model is taked is that infrared rays passive electromagnetic valve automatic flushing device is made up of therebetween with closed two ends external screw thread interface plastics electromagnetic valves (abbreviation electromagnetic valve) controller and is connected by lead.Controller is made of P2288 Thermoelectric Infrared Sensor, SNS9201 infrared ray sensing signal processor, delay circuit, drive circuit, relay and resistance, electric capacity assembling.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 of one segment length's spanner are respectively arranged in the valve body both sides, and its outer end is the external screw thread interface, and valve is put and 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 passive electromagnetic valve automatic flushing device.

Fig. 5 is the controller electrical schematic diagram of infrared rays passive electromagnetic 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 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, a spring 7 is housed in hollow, and 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, and through hole lid 2 is placed on the rubber diaphragm 1, and rubber diaphragm is contained between valve upper body 4 valve bodies 11.Also have a through hole H on the through hole lid 2, 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, enter the M chamber through through flow hole H, because spool is closed through flow hole N, make fluid can not enter the E chamber, 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 flow 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 flow hole N, and electromagnetic valve is in closed condition.

In Fig. 4, controller is arranged on the top of urinal, and its window is towards the urinal forward position, and closed two ends external screw thread interface plastics electromagnetic valve is serially connected on the flushing pipe of urinal and is connected by lead therebetween.

In Fig. 5, controller is by P2288 Thermoelectric Infrared Sensor V1, and (R2, C2) V2, drive circuit (R3,9013) V3, relay J 1 and resistance, electric capacity assembling constitute for SNS9201 infrared ray sensing signal processor IC1, delay circuit.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), and whenever P2288 Thermoelectric Infrared Sensor V1, when accepting a human body infrared energy, electromagnetic valve is just opened a period of time, closes automatically then.

In Fig. 5, P2288 Thermoelectric Infrared Sensor V1, monitor space, urinal forward position by window, then just receive the faint infrared energy of 7-14 μ m that human body distributes as the people station, and make it to convert to 14 pin that voltage signal is defeated by SNS9201 infrared ray sensing signal processor IC1, amplification through its inside, the comparison output signal high level, again after delay circuit V2 handles, drive 9013 triodes by the output of 2 pin and drive relay J 1 work, connect power of electromagnetic valve, then electromagnetic valve is opened, and jet water spout is outwards washed by water.Time delay, at the end relay disconnected power of electromagnetic valve, and closed electromagnetic valve, jet water spout stop bath.
