Problems solved by technology

In fact, there are many disadvantages in the existing gas leakage detection scheme: firstly, a leak detection process hole is reserved on the injector tube, which has high requirements on the manufacturing process, which increases the manufacturing cost of the injector tube to a certain extent; Second, during leak detection, it is necessary to insert a special clip into the leak detection process hole, and then block the nozzle, which is inconvenient to operate and takes a long time for the leak detection process

Embodiment 1

[0047] An embodiment of a gas leakage detection system for a gas cooker proposed by the present invention, such as figure 2 shown. The gas cooker to which the embodiment of the gas leakage detection system is applied also includes two injection pipes 1, such as Figure 7 As shown, the two ejector tubes 1 each include an inlet port 1-1, and the two ejector tubes 1 adopt an integrally formed structure.

[0048] The embodiment of the gas leakage detection system includes: a gas valve 7; two nozzles 5 respectively provided with a first end portion 5-1 and a second end portion 5-2; two gas supply pipes 6, the two supply pipes The air pipes 6 are respectively arranged between the nozzle 5 and the gas valve 7; two dampers 3; two springs 4;

[0049] Each of the two injection tubes 1 corresponds to an intermediate element 2 . Each intermediate element 2 includes: two air inlets 2-1; a threaded hole 2-2 for installing the nozzle 5; The two intermediate elements 2 adopt an integral ...

Embodiment 2

[0057] The present invention also proposes another embodiment of a gas leakage detection system for a gas stove. The gas cooker to which the embodiment of the gas leakage detection system is applied also includes two injection pipes 1, such as Figure 8 As shown, the two ejector tubes 1 each include an inlet port 1-1, and the two ejector tubes 1 adopt an integrally formed structure.

[0058] The only difference between this embodiment 2 and embodiment 1 is that in order to further enhance the fixing effect between the intermediate element 2 and the inlet end 1-1 of the ejector tube 1, this embodiment further sets a fourth element on the intermediate element 2. Mounting holes. Correspondingly, a third installation hole 1-1-3 is further provided on the transverse end face of the inlet end 1-1 of the injection pipe 1, as Figure 8 shown. The third installation hole 1 - 1 - 3 and the fourth installation hole are used to fix the intermediate element 2 on the inlet end 1 - 1 of t...

Embodiment 3

[0060] The present invention also proposes another embodiment of a gas leakage detection system for a gas stove. The gas cooker to which this embodiment of the gas leakage detection system is applied also includes two injection pipes 1, such as Figure 9 As shown, the two ejector tubes 1 each include an inlet port 1-1, and the two ejector tubes 1 adopt an integrally formed structure.

[0061] The difference between this embodiment 3 and embodiment 1 mainly lies in:

[0062] One, only one air inlet 1-1-1 is set at the air inlet 1-1 of each injection pipe 1, as Figure 9 shown.

[0063] Second, the intermediate element 2 adopts a sheet structure, and the ears of the intermediate element 2 are provided with screw installation holes, and the air inlet end 1-1 of the ejector tube 1 is also provided with corresponding screw installation holes. After the gas leakage detection is completed, the assembly of the gas cooker can be further completed, that is, a screw is sequentially pa...

Abstract

The invention provides a gas stove and a gas leakage detection system for the gas stove. The gas leakage detection system for a gas cooker proposed by the present invention includes: a gas valve; a nozzle provided with a first end portion and a second end portion; an air supply pipe, the air supply pipe is arranged on the nozzle and the gas between the valves; air flaps; an intermediate element connected to the intake end of the ejection pipe, the intermediate element includes an air inlet, and the air inlet matches the air flaps; the air flaps and nozzles are fixed on On the intermediate element; the first end portion of the nozzle is configured to be closed for gas leakage detection. By adopting the technical solution of the invention, the leak detection process can be simplified and the leak detection speed can be improved.

Description

【Technical field】 [0001] The invention relates to the field of gas cookers, in particular to a gas leakage detection technology for the gas cooker. 【Background technique】 [0002] Existing gas cooker, must carry out gas leakage detection after main components such as gas supply pipe, injection pipe and gas valve are assembled. A structural schematic diagram of an existing gas stove gas supply system, such as figure 1 As shown, a leak detection process hole must be reserved on the injection pipe for gas leakage detection. After the detection is completed, the leak detection process hole should be sealed with screws. In fact, there are many disadvantages in the existing gas leakage detection scheme: firstly, a leak detection process hole is reserved on the injector tube, which has high requirements on the manufacturing process, which increases the manufacturing cost of the injector tube to a certain extent; Second, during leak detection, it is necessary to insert a special c...
