[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Example 1

[0026] Reference Figure 1-7A leak-proof and air-sealing mechanism for a cartridge stove, comprising a fixing frame 1 fixed to the inner wall of the gas tank installation space of the cartridge stove, two micro switches 9 and a connected warning light 12, a connecting tube 2 is installed at the other end of the fixing frame 1, and the two ends of the connecting tube 2 are respectively connected to the gas tank joint and the gas tank of the cartridge stove, a sealing plug 4 is slidably provided in the middle of the connecting tube 2, the upper end of the sealing plug 4 extends to the outside of the connecting tube 2 and is connected to a roller 6, a compression spring 7 is sleeved on the rod body of the sealing plug 4 located inside the connecting tube 2, a rocker 8 is hingedly connected to the rear side of the connecting tube 2 corresponding to the roller 6, a guide shell 3 is fixed to the upper surface of the fixing frame 1, and the inside of the guide shell 3 is opposite to the roller 6. A linkage plate 5 is provided at the end of the seesaw 8 away from the roller 6, and micro switches 9 are respectively installed on the upper end of the linkage plate 5 and at the external cassette stove gas switch. The external gas switch is provided with a trigger block 10 corresponding to the micro switch 9. The two micro switches 9 and the prompt light 12 are connected in series, and when the external cassette stove is not in use, that is, the gas switch is in the off state, the trigger block 10 arranged on the gas switch presses and triggers the adjacent micro switch 9. There is a labor-saving lever between the linkage plate 5 and the seesaw 8, that is, the distance from the hinge of the seesaw 8 to the roller 6 is much smaller than the distance to the linkage plate 5, so as to facilitate overcoming the elastic force of the compression spring 7.

[0027] Example 2

[0028] Reference Figure 1-7 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0029] A roller 13 is rotatably mounted on the middle of the upper end of the linkage plate 5. The outer ring surface of the roller 13 is a smooth surface. The setting of the roller 13 allows the protective cover to press the upper end of the linkage plate 5 when the protective cover on the gas tank on the cartridge furnace is reset after the gas tank is replaced by the external cartridge furnace, thereby pushing the linkage plate 5 to move downward. In this process, the setting of the roller 13 can reduce the friction resistance between the linkage plate 5 and the external protective cover, that is, when the protective cover is turned over, the linkage plate 5 can be easily pushed to move downward; the lower end of the linkage plate 5 is rotatably mounted with a roller 14, and the seesaw 8 The end away from the roller 6 is arc-shaped and contacts with the outer ring surface of the roller 14. The setting of the roller 14 makes the linkage plate 5 and the seesaw 8 in rolling contact, that is, the friction resistance between the linkage plate 5 and the seesaw 8 is smaller, so that it is convenient for the linkage plate 5 to push the seesaw 8; the outer ring surface of the lower end of the sealing plug 4 is provided with a sealing sleeve 15, and the sealing plug 4 contacts with the inner wall of the connecting tube 2 through the sealing sleeve 15. The setting of the sealing sleeve 15 improves the sealing between the connecting tube 2 and the sealing plug 4, that is, it prevents the gas in the gas tank from leaking from the gap between the two.

[0030] An arc groove is provided on the rod body of the roller 6, and an externally smooth rod-shaped connecting end is provided at the end of the seesaw 8 corresponding to the arc groove. The setting of the arc groove makes it easier to make the connection between the seesaw 8 and the roller 6 more stable; a connector 11 is installed at one end of the connecting tube 2, and the end of the connecting tube 2 away from the connector 11 is connected to the gas tank joint in the external cassette furnace. The connector 11 is an existing joint for connecting the gas tank, which facilitates the connection between the gas tank and the connecting tube 2; the warning light 12 has its own power supply, and the warning light 12 is installed on the bottom surface of the gas tank installation space of the external cassette furnace. Since the warning light 12 has its own power supply (which can be a rechargeable electronic device or a rechargeable battery), the warning light 12 installed in the gas tank installation space can provide a more conspicuous reminder to personnel when they replace the gas tank.

[0031] Using principle and advantages: During the use of the utility model, the two ends of the connecting tube 2 are respectively connected to the external gas tank and the gas tank joint in the cassette stove, that is, the gas in the gas tank can enter the gas tank joint of the cassette stove through the connecting tube 2, and then flow to the subsequent stove head through the gas tank joint, thereby realizing gas supply. In the above process, since the microswitch 9 is a normally open switch, that is, when the microswitch 9 is not triggered, the microswitch 9 and the prompt light 12 in series are in a passage state, and then the prompt light 12 can be turned on.

[0032] Therefore, when personnel replace the gas cylinder, if the personnel do not turn off the gas switch, the trigger block 10 on the gas switch cannot trigger the microswitch 9 at the gas switch at this time, that is, this microswitch 9 is in a passage, and then when the personnel open the protective cover at the gas cylinder on the gas stove, due to the lack of the pressure of the protective cover, the microswitch 9 on the upper end of the linkage plate 5 is in an untriggered state, that is, it is in a passage, so that the two microswitches 9 are connected with the prompt light 12, that is, the prompt light 12 lights up to prompt the personnel, and in this process, when the protective cover is removed from the upper end of the linkage plate 5, its compression spring 7 pushes the sealing plug 4 to move downward until the inside of the connecting tube 2 is blocked, that is, the inside of the connecting tube 2 is cut off at this time, and the gas cannot circulate. At the same time, when the sealing plug 4 moves downward, it drives the seesaw 8 to rotate, that is, the end of the seesaw 8 away from the roller 6 pushes the linkage plate 5 to move upward.

[0033] When the gas cylinder is replaced, the personnel reset the external protective cover. In the process, the protective cover squeezes the upper end of the linkage plate 5, that is, the protective cover pushes the linkage plate 5 to move downward, and when the linkage plate 5 moves downward, the sealing plug 4 is lifted upward through the seesaw 8 and the roller 6, that is, the inside of the connecting tube 2 is unobstructed at this time; in summary, when the present scheme is used, through the setting of the two micro switches 9, the prompt light 12 and the linkage plate 5, when the personnel replace the gas cylinder, the present mechanism can confirm the on-off position of the gas switch on the external cassette stove, so as to remind the personnel in time when the personnel forget to turn off the gas switch, so as to avoid the gas leakage in the gas cylinder after the gas cylinder is replaced, resulting in waste of resources and danger to the personnel, and under the action of the linkage plate 5, the seesaw 8 and the sealing plug 4, the connecting tube 2 can be automatically blocked when the gas cylinder is replaced, so as to avoid gas leakage when the tank is replaced, and since there are no other electrical components except the micro switch 9 and the prompt light 12 in the present scheme, the influence of the high temperature generated when the cassette stove is used on the present mechanism can be effectively avoided.

[0034] It should be further explained that the setting of the roller 13 can reduce the friction resistance between the linkage plate 5 and the external protective cover, that is, when the protective cover is flipped, the linkage plate 5 can be easily pushed downward; the setting of the roller 14 makes the linkage plate 5 and the seesaw 8 in rolling contact, that is, the friction resistance between the linkage plate 5 and the seesaw 8 is smaller, so that it is convenient for the linkage plate 5 to push the seesaw 8; the setting of the sealing sleeve 15 improves the sealing between the connecting tube 2 and the sealing plug 4, that is, it prevents the gas in the gas tank from leaking from the gap between the two; the setting of the arc groove makes it easier to make the connection between the seesaw 8 and the roller 6 more stable; the setting of the connector 11 makes it easier to connect the gas tank to the connecting tube 2; the warning light 12 installed in the gas tank installation space can serve as a more conspicuous improvement for personnel when they replace the gas tank.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
