Abstract

The utility model belongs to a shutter for a gas burner, which is especially suitable for an automatic timing shutter for a domestic gas burner. The switch automatic timing shutter is composed of three portions, wherein, the first portion is a gas inlet and outlet shutter, the basic structure of the gas inlet and outlet shutter is the same as the structure of a shutter of an existing gas burner, only a main shaft rod of the shutter is lengthened according to the requirements, and moreover, the main shaft rod is sheathed with a combining part; the second portion is a mechanical type timer, the basic structure of the mechanical type timer is the same as the structure of an existing mechanical type timer, an original solid shaft is designed into a hollow shaft according to the requirements, and the hollow shaft is sheathed with a cam; the third portion is a combining part which combines the gas shutter and the timer into integration, and the combining part comprises eight components. The third portion is the core portion of the utility model; the shutter of an original gas burner and the timer are organically combined into integration through the design of the third portion, and therefore, the function that a gas burner can be automatically closed within the specified time is realized. The principle and the realization method of the utility model are detailed in the specification and the accompanying drawing.

Description

The timing automatic switch of closing of gas burner

The utility model relates to a kind of can the unlatching or the timing automatic gas burner device of closing.Its device is to constitute with mechanical part.

At present, known gas cooker switch structure is to be made of assemblies such as party, piezoelectric ceramics, spring, main shaft, shell in the turnover coal gas mouth of pipe, the switch.Its effect can only be manually opened or be closed gas burner, does not have the timing automatic gas burner function of closing, and people can only keep marquis's operation.Yet how people need to close gas burner is timing automatic when using gas burner to boil thing in daily life, so that find time do other thing, or avoid causing accidents such as fire when serious because of the not careful paste thing that boils.

The purpose of this utility model provides a kind of mechanical gas cooker switch, and it can not only finish function manually opened, that close and regulate gas burner, and can realize the timing automatic gas burner of closing.

The purpose of this utility model is achieved in that the timing automatic switch of cutting out of gas burner is made up of three parts: one, jet, two, mechanical timer, three, the bonded block of jet and timer.Wherein first be to existing jet the axle carried out adding long process, be convenient to combine with timer.Second portion is that the solid shafting to the prior mechanical timer is modified into hollow shaft, and the axle of being convenient to jet passes.Third part is the innovation parts.When need open gas burner, pin the jet handle under the drive of switch spindle, closed disk is closed in starting and half tooth positioning disc leaves original position 8mm synchronously left, rotates counterclockwise 90 degree simultaneously, lights gas burner.Make the stressed elongation of return spring, the protruding top on the closed disk of starting pass has also rotated counterclockwise 90 degree with disk and has left original position.Keep 90 degree to loose one's grip subsequently, this moment the shell fragment card head into make starting close closed disk in the half tooth positioning disc tooth can not return, keep gas burner opening.If need the timing automatic gas burner of closing, then hold regularly and press regularly disk after the disk handle clockwise rotates setting-up time, make the cam on the timer and the protruding top that resets be moved to the left 8mm, make timer cam and shell fragment card at grade.When the timer cam slowly returned to original position with timer, the timer cam backed down the shell fragment card and makes and leave half tooth positioning disc tooth, and starting this moment is closed closed disk and clockwise rotated 90 degree and close gas burner under the effect of return spring.Close in starting and to withstand the timer protruding top that resets after protruding top on the closed disk resets and make timer move right 8mm and restore.Treat to use next time.Thereby reach timing automatic purpose of closing gas burner.But this novel switched also manual-lock or regulated at will gas burner.

Owing to adopt such scheme, on the basis of improving existing jet and mechanical timer, increase some bonded blocks, make it to form a novel gas switch.Technology maturation, simple in structure, do not need other power drive.It can not only be finished hand switch and regulate the gas burner function, and can the timing automatic gas burner of closing.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is left TV structure figure.

Fig. 2 is plan structure figure.

Fig. 3 is main TV structure figure.

Fig. 4 is the A--A cutaway view.

Fig. 5 is the B--B cutaway view.

Among the figure 1, jet 2, mechanical timer 3, starting close reset protruding top 8, starting of closed disk 4, half tooth positioning disc 5, return spring 6, shell fragment card 7, timer and close the protruding top 9 of closed disk, timer cam 10, regularly disk handle 11, jet handle 12, jet main shaft 13, jet spring 14, timer positioning screw 15, fixed head 16, standing screw 17, coal gas turnover pore 18, timer hollow shaft

In the embodiment shown in fig. 1, be connected with an end stay column of shell fragment card (6) and return spring (5) on the fixed pan of jet (1), and fix tightly.Be with jet spring (13), starting pass closed disk (3), half tooth positioning disc (4), mechanical timer (2), timer cam (9), timing disk handle (10), jet handle (11) on the jet main shaft (12).Wherein starting pass closed disk (3), half tooth positioning disc (4) and jet handle (11) are fixed on the jet main shaft, rotate with main shaft.And timer cam (9) and timing disk handle (10) are fixed on the timer hollow shaft (18), rotate with hollow shaft.Two startings are closed the protruding tops of closed disk (8) and are fixed on starting symmetrically and close on the closed disk (3), and two timers protruding top (7) that resets is fixed on the back cover of timer (2) symmetrically.Timer positioning screw (14) passes timer (2) locating hole and is fixed on the fixed head (15), and the locating hole diameter on the timer (2) should be greater than the diameter 1mm of timer positioning screw (14), and making timer can be a move left and right 8mm with the jet main shaft.The internal diameter of timer hollow shaft should be greater than the diameter 1mm of jet main shaft, so that timer hollow shaft (18) drives timer cam (9) and whole timer (2) move left and right.One end of return spring (5) colludes on the stay column on jet (1) fixed pan, and the other end colludes in starting and closes on the closed disk (3).

In the embodiment shown in Figure 2, overlook starting to close the protruding top of closed disk (8) be that triangle is upright and close on the closed disk (3) in starting admittedly, the timer protruding top (7) that resets also is that triangle is upright solid on the back cover of timer (2).

In the embodiment shown in fig. 3, the main front of disk handle (10) of looking regularly is marked with regularly minute numerical value (numerical values recited can according to the maximum timing value nominal of timer).

In the embodiment shown in fig. 4, can see that it is to be with arc shape that the protruding top of closed disk (8) is closed in starting, jet main shaft diameter is less than timer hollow shaft (18) internal diameter 1mm.

In the embodiment shown in fig. 5, the number of teeth on the half tooth positioning disc (4) can regulate as required gas burner flame size shelves a number determine that a teeth groove can be regulated one grade of flame.It also is to be with arc shape that the protruding top of closed disk (8) is closed in starting.
