Description

A leakage-proof charging device for a gas stove

technical field

The invention relates to a gas stove, in particular to a leakage-proof charging device for the gas stove.

Background technique

The power supply used by the existing gas stove pulse igniter, flameout protection device, etc. generally uses batteries, but the battery power is limited. Therefore, when the gas stove has been used for a period of time, when the battery power is lower than a certain value, the gas stove ignition and other functions will not work. If the gas stove cannot work normally, the user needs to replace the battery during the use of the gas stove. On the one hand, it increases the cost of use. On the other hand, the improper recycling of the replaced battery will also cause pollution to the environment. Therefore, it is very necessary to improve the power supply structure of the gas stove. Patent Publication No. CN209462068U A gas stove battery self-charging device, which provides a technical solution, which uses a thermocouple beam to convert the thermal energy of the flame when the gas stove is working into electrical energy, and charges the battery to achieve the purpose of requiring no or less replacement of the battery , but this solution also has a technical defect. Since the battery is directly connected to the charging device, there is no switch in the middle. Therefore, when the gas stove is working, the voltage output by the charging device is higher than the battery voltage. At this time, the battery can be charged, but when the gas stove is working When it is not working, because the thermocouple beam has no flame heating, it cannot generate voltage. Since the battery voltage is higher than the charging device, the battery will in turn supply power to the charging device, resulting in leakage. Since the non-working time of the gas stove is much longer than the working time, Therefore, it is very necessary to solve this technical problem.

Detailed ways

The following is a specific embodiment of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to this embodiment.

As shown in Figures 1 and 2, the present invention provides a leakage-proof charging device for a gas stove, comprising: a gas stove burner 1, a thermocouple bundle 2, a booster voltage regulator circuit board 3, a plug valve 4, a micro-motion The switch 5 and the battery assembly 6 are composed, the thermocouple bundle 2 is installed on the gas stove burner 1, the micro switch 5 is installed on the plug valve 4, the thermocouple bundle 2, the booster voltage regulator circuit board 3 , the micro switch 5 , and the battery assembly 6 are connected in sequence through the connecting wire 7 . The plug valve 4 includes: a main body 410, a rotating shaft 420, a cover plate 430, a return spring 440, a pressure plate 450, a positioning plate 460, a circlip 470, and a fixing bracket 480. The cover plate 430, return spring 440, The pressing plate 450 , the positioning plate 460 and the fixing bracket 480 are sequentially sleeved on the rotating shaft 420 , and the retaining spring 470 is installed in the positioning groove 4202 of the rotating shaft 420 . A driving plane 4201 is machined on the rotating shaft 420, and a hollow hole matching plane 4601 is provided on the positioning plate 460. The driving plane 4201 of the rotating shaft 420 and the hollow hole matching plane 4601 of the positioning plate 460 are mutually limited, so that the positioning plate 460 and the rotating shaft 420 can rotate synchronously; there is a positioning boss 4801 on the fixed bracket 480, the pressure plate 450 is provided with a positioning hole 4501 for the positioning boss 4801 to pass through, and the positioning plate 460 is provided with a positioning hole 4501 for positioning The positioning hole 4602 through which the boss 4801 passes.

The working principle of the above-mentioned anti-leakage charging device for gas stoves is that when the rotary shaft 420 of the plug valve 4 is pressed down, the retaining spring 470 disposed in the positioning groove 4202 of the rotary shaft 420 simultaneously presses down the positioning plate 460 and the pressing plate 450 , at this time, the pressure plate 450 presses the micro switch pressure reed 510, the micro switch 5 is turned on, and at the same time, the positioning hole 4602 on the positioning plate 460, the positioning hole 4501 on the pressure plate 450 and the positioning boss 4801 on the fixing bracket 480 Disconnect, in the next step, the rotating shaft 420 of the rotary plug valve 4 rotates at a certain angle to open the air flow channel in the plug valve body 410, the gas stove burner 1 is ignited, the flame heats the thermocouple bundle 2, and the thermocouple bundle 2 generates a current through the After the voltage regulator circuit 3 boosts and stabilizes the voltage, it flows through the connected micro switch 5 to charge the battery pack 6. During the rotation of the rotating shaft 420, due to the difference between the driving plane 4201 of the rotating shaft 420 and the positioning plate 460 The hollow holes cooperate with the planes 4601 to limit each other, so that the positioning plate 460 and the rotating shaft 420 rotate synchronously, the positioning holes 4602 of the positioning plate 460 are staggered from the positioning bosses 4801 on the fixed bracket, and the positioning bosses 4801 bear against the upper surface of the positioning plate 460 , the return spring 440 cannot push the positioning plate 460 and the pressure plate 450 back. When there is no external force to press down the rotating shaft 420, the micro switch pressure spring 510 is also always pressed by the pressure plate 450, and the micro switch 5 is kept connected. ,As shown in Figure 4. When the gas stove is turned off, the rotating shaft 420 of the plug valve 4 is rotated to the closed position. For the same reason that the driving plane 4201 of the rotating shaft 420 and the hollow hole matching plane 4601 of the positioning plate 460 are mutually limited, the positioning plate 460 is synchronized. Rotate to the closed position. At this time, the positioning hole 4602 on the positioning plate 460 is aligned with the positioning boss 4801 on the fixing bracket 480. The pressure plate 450 and the positioning plate 460 are pushed away from the micro switch pressure spring 510 by the return spring 440. When the switch 5 is turned off, the circuit between the battery pack 6 and the booster voltage regulator circuit 3 is disconnected, and the battery pack 6 cannot supply power to the booster regulator circuit 3, so as to prevent the charging device from leaking electricity when the gas stove is not working. .

In this embodiment, the thermocouple bundle 2, the booster voltage regulator circuit board 4, the air circuit structure in the plug valve body 410, and the microswitch 5 all use the existing conventional technology, so the structure is here No further details.
