Abstract
The utility model relates to an electronic timing gas pressure-reducing valve, which is characterized in that an electronic timer is arranged on a general gas pressure-reducing valve; a power switch of the electronic timer is formed by a pressure sensing switch arranged on the gas pressure-reducing valve. The utility model can automatically time and remind a user after gas is opened; simultaneously, the timer can be restarted at any time after the gas is used; the timing time can be arbitrarily regulated. If the timing can not be required, the timer can also be turned off. The utility model has the advantages of convenient operation, flexibility and safety.
Description
The utility model is a kind of electronic timing combustion gas reduction valve.It can be after combustion gas be opened, and regularly newspaper is the user.
In prior art, Chinese patent has been announced the combustion gas reduction valve that several timings are closed, and their mentality of designing mainly is the function that the realization timing automatic is closed combustion gas.Regularly closing is a kind of compulsory safety measure, for the user, not necessarily needs enforceable closing sometimes, and only needs suitably regularly to remind, and like this, can guarantee safety, can continue follow-up culinary art again, need not drive valve again again.Therefore, the combustion gas reduction valve that this timing is closed needs the users that regularly remind just not too suitable to those, can not reach not only convenient, but also the application requirements of safety.
The purpose of this utility model is at the problem in the prior art, and a kind of electronic timing combustion gas reduction valve that can regularly remind the user is provided.
For achieving the above object, solution of the present utility model is as shown in Figure 1: it has a combustion gas reduction valve, its key structure is to be provided with an electronic timer on described combustion gas reduction valve, and the power switch of this electronic timer is made of the pressure-sensitive switch that is located on the combustion gas reduction valve.
By above-mentioned solution as can be seen, the utility model has been set up a kind of electronic timer on existing combustion gas reduction valve, and the power switch of this electronic timer has adopted a kind of pressure-sensitive switch by the control of combustion gas reduction valve, and it can be closed by promoting behind the combustion gas reduction valve pressurized.After the power switch closure, timer begins to start, and when timing one arrives, it just sends tweeting sound and reminds the user, realizes the timing of whole cooking time; Simultaneously, the user also can restart timer and regulate timing arbitrarily in any moment of using combustion gas, to realize the timing of a certain Stewed Dish of cooking process; If need not regularly can also turn-off timer.The utility model has realized that the automatic timing newspaper is user's function, and easy to operate, flexible, safety.
Describe structure of the present utility model and working principle in detail according to embodiment below.
Fig. 1, functional-block diagram of the present utility model.
Fig. 2, embodiment's 1 pressure-sensitive switch structural representation.
Fig. 3, embodiment's 2 pressure-sensitive switch structural representation.
The enlarged view of I portion among Fig. 4, Fig. 2.
The circuit theory diagrams of Fig. 5, the utility model electronic timer.
Referring to Fig. 2, the combustion gas reduction valve adopts a kind of manometric combustion gas reduction valve that has, and described pressure-sensitive switch can constitute by being located at pointer contact 1 in the combustion gas reduction valve pressure gauge outfit and the conducting plate 2 that is located on the dial plate.When combustion gas reduction valve pressurized, the clockwise deflection of meter pointer, then pointer contact 1 contacts with conducting plate 2, thereby makes the power switch closure of electronic timer, electronic timer work.
Referring to Fig. 3,4, if the combustion gas reduction valve is a kind of manometric general gas reduction valve of not being with, then described pressure-sensitive switch is made of the piston-type pressure switch that is located in the combustion gas reduction valve, this pressure switch is made of piston cavity 3, piston 4, piston stopper 5 and a spring 6 that is located in the combustion gas reducing valve body (17), wherein piston 4 and piston cavity diapire or be located at conducting plate 7 on the diapire switch contact that partners.When combustion gas reduction valve pressurized, piston 4 contacts with piston cavity diapire or conducting plate 7 along upwards operation of piston cavity, switch on then, electronic timer work.
The circuit form of electronic timer described in the utility model is a lot, and in general, existing timing, delayer can both be applicable to the utility model, only the power switch of timing or delayer need be changed to above-mentioned gang switch and get final product.This example has adopted one than general purpose timer, its structure is referring to Fig. 5, it is is mainly connected and composed by delay circuit 8, oscillator 11 and the loudspeaker 12 that is connected on oscillator output end, and wherein the potentiometer in the delay circuit 9 is used to regulate delay time, and button 10 is the knobs that reset of this delay circuit; Oscillator 11 also can adopt integrated devices such as various music, voice; Switch 13 in the circuit is aforesaid combustion gas reduction valve pressure-sensitive switch, and in parallel with it is self check push switch 14, series connection with it be normally closed switch 15.Its working principle is: when gas is opened certainly, and combustion gas reduction valve pressurized, then power switch 13 closures, delay circuit 8 triggers, delay time one arrives, and it is just from trigger signal of 3 pin output, make oscillator 11 work, the oscillator signal of its output drives the tweeting sound that loudspeaker 12 sends interruption.In when culinary art, can press knob 10 at any time, then delay circuit restarts and carries out new time-delay; Can change delay time by regulator potentiometer 9.In addition, when right gas is not opened, can press 14 pairs of these time circuits of self check knob and carry out self check; Disconnect normally closed switch 15 electronic timer is quit work, recover common combustion gas user mode.
