Description

Technical Field

[0001] The present disclosure relates to the technical field of household appliances, and in particular to a device for testing the lower pressure of a gas cooker and a gas cooker. Background Art

[0002] The gas stove switch is equipped with a child lock. A certain amount of downward pressure is required to open the child lock, and then the valve can be rotated to open the ignition operation. The child lock mechanism is set on the valve body. If the downward pressure is not large enough, the valve cannot be opened, and the gas cannot come out and the ignition will fail. At present, the downward pressure is tried by the user. After success, they will get used to this downward pressure. If they don’t know the specific value, the situation will occur that if someone else operates the gas stove, the gas stove will still fail to ignite.

[0003] Moreover, in order to test whether the valve body that controls the gas intake in the stove is qualified, a push-pull force gauge is needed to test whether the valve body can be rotated to 90° when the force is ≤20N (or other values). If it can be rotated, it is qualified, and if it cannot be rotated, it is unqualified. In the process of this method of testing, since the push-pull force gauge is held by hand and the push-pull force gauge itself is relatively heavy, it is difficult to ensure the pressure when using the switch gas stove, and the speed of the hand pressing down is also difficult to be consistent with the user's usage scenario. It is impossible to identify whether the gas valve is actually opened in the user's usage scenario, and whether it can be ignited normally. In actual use, it is easy to let go and turn off the fire.

[0038] The present disclosure will be further described below by way of embodiments, but the present disclosure is not limited thereto within the scope of the described embodiments.

[0039] In the embodiments of the present disclosure, prefix words such as "first" and "second" are only used to distinguish different described objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of ordinal numbers and other prefix words for distinguishing described objects in the embodiments of the present disclosure does not constitute a limitation on the described objects. The statements of the described objects refer to the descriptions in the context of the claims or embodiments, and should not constitute unnecessary limitations due to the use of such prefix words. In addition, in the description of this embodiment, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0040] Example 1

[0041] Figure 1 This is a schematic diagram of the modules of a test device for the downward pressure of a gas stove provided by an exemplary embodiment of the present disclosure. The test device includes: a pressure tester 1 and a display screen 2; in the figure, the dashed line represents a communication connection, and the solid line represents an electrical connection.

[0042] The pressure tester 1 is communicatively connected to the display screen 2.

[0043] The pressure tester 1 is disposed between the switch and the valve body of the gas stove, and the switch is drivingly connected to the pressure input end of the pressure tester 1.

[0044] The pressure tester 1 is used to detect the downward pressure applied by the switch and send the downward pressure to the display screen 2.

[0045] The display screen 2 is used to display the downward pressure.

[0046] Among them, the pressure tester can be an elastic pressure gauge, an electrical pressure gauge, a bourdon tube pressure gauge, a diaphragm pressure gauge, an electric pressure transmitter, a pneumatic pressure transmitter, etc. according to the actual situation.

[0047] The display screen 2 can be placed or fixed on the panel of the gas stove, or can be set at other positions convenient for the user to view.

[0048] During actual use when the user presses down the switch to ignite, the display screen shows in real time the downward pressure of the switch detected by the pressure tester.

[0049] In a test scenario, if the downward pressure falls within a preset downward pressure value range, the valve can open (rotate), the fire can be ignited normally, and continuous combustion can prove that this valve body meets the requirements; if the downward pressure exceeds this preset downward pressure value range (such as being greater than the maximum required pressure value as the upper limit value) and still cannot rotate, or the fire goes out when the hand is released, then this valve body is unqualified. The preset downward pressure value range is related to the actual structure of the stove.

[0050] In the daily use scenario, the user can view in real time the current downward pressure of the switch, clearly master the current downward pressure value, which is convenient for judging the specific downward pressure value range required to open the valve. When the downward pressure falls within this range, the valve can open (rotate), the fire can be ignited normally, and when the downward pressure exceeds this range, the fire cannot be ignited normally.

[0051] In this embodiment, a pressure tester is installed between the switch and the valve body of the gas stove, and a pressure display screen is installed on the panel. During the process of pressing the switch down, the pressure tester is used to accurately measure the downward pressure of the switch in an actual usage scenario, and the downward pressure is displayed in real time on the pressure display screen, so that the user can clearly grasp the current downward pressure value and judge the specific downward pressure value range required to open the valve. If the downward pressure falls within this range, the valve can be opened (rotated) and ignited normally. If the downward pressure exceeds this range, it cannot be ignited normally. In the test scenario, if the downward pressure falls within the preset range and the valve cannot be rotated or the flame is extinguished when the hand is released, the valve body is unqualified.

If the downward pressure falls within this range, the valve can be opened (rotated) and ignited normally. If the downward pressure exceeds this range, it cannot be ignited normally. In the test scenario, if the downward pressure falls within the preset range and the valve cannot be rotated or the flame is extinguished when the hand is released, the valve body is unqualified.
