Description

Technical Field

[0001] The invention relates to the technical field of gas stove installation, in particular to an explosion-proof alarm device for a gas stove. Background Art

[0002] When the gas stove is in use, it needs to be connected to the gas main through pipe fittings. During the connection of the gas pipe fittings, the sealing of the connection is very important. Once the sealing is insufficient, it is easy to cause gas leakage and explosion.

[0003] When the existing gas stove is in use, it lacks a device for detecting gas. When the gas is not burning completely, the user cannot find it in time. If a gas alarm needs to be installed, it needs to be purchased temporarily. At the least, it is easy to cause gas poisoning, and at worst, it is easy to cause an explosion, and the safety factor is low. Summary of the invention

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-6 A gas stove explosion-proof alarm device of the present invention comprises a gas stove body 1, wherein a mounting groove 2 is arranged inside the gas stove body 1, a shell 3 is drawn out and arranged inside the mounting groove 2, a box 8 and a gas leakage detector 7 are fixedly arranged inside the shell 3, a negative pressure fan is arranged inside the box 8, an air outlet end of the negative pressure fan is provided with an air outlet pipe penetrating the box 8, an air suction end of the negative pressure fan is provided with an air suction pipe 9 penetrating the box 8, a transfer tube 10 is arranged at one end of the air suction pipe 9, a detection end of the gas leakage detector 7 is installed inside near the air outlet pipe, an alarm 6 is fixedly arranged outside the shell 3, and the alarm 6 is electrically connected to the gas leakage detector 7;

[0028] The upper end of the gas stove body 1 is provided with a groove 11, the interior of the groove 11 is provided with a fixing plate 12, the fixing plate 12 is provided with a plurality of air inlet holes 13, the lower end of the fixing plate 12 is provided with a bottom shell 15, the lower end of the bottom shell 15 is provided with a butt joint 16, the interior of the butt joint 16 is provided with a sealing ring 17, the transfer tube 10 can be inserted into the interior of the butt joint 16, and the bottom shell 15, the butt joint 16 and the positioning block 19 are connected;

[0029] In this embodiment, the gas leakage detector 7 and the box body 8 are both installed in the shell 3. The gas leakage detector 7 is very common nowadays and has the same principle as the gas detectors on the market. It is not necessary to describe it too much here. When the gas stove body 1 is in use, the negative pressure fan in the box body 8 is started. At this time, the gas at the gas stove body 1 will enter the suction pipe 9 through the air inlet 13, and then be discharged at the air outlet pipe, so that the gas leakage detector 7 can detect the gas. When it is detected that the gas concentration in the gas is too high, the control circuit will trigger the alarm 6, and the alarm can be sent to the outside through the alarm 6. At this time, the excess gas in the shell 3 will be discharged through the exhaust hole 5. When the gas is not fully burned, the user can find it in time, and the safety factor is high. The gas leakage detector 7 is used as a set with the gas stove body 1, and there is no need to temporarily purchase the gas leakage detector 7. The installation position of the gas leakage detector 7 is not considered, thereby improving the safety factor of the gas stove body 1 when in use;

[0030] When the intake pipe 9 is docked with the docking pipe 16 , the friction between the adapter pipe 10 and the sealing ring 17 can make the adapter pipe 10 more firmly inserted into the docking pipe 16 .

[0031] Furthermore, the alarm 6 includes a sound alarm and a light alarm. After receiving the signal from the gas leak detector 7 , the light alarm will emit a warning light, and after receiving the signal from the gas leak detector 7 , the sound alarm will emit a warning sound.

[0032] Furthermore, a guide groove is provided on the inner wall of the installation groove 2, and guide blocks 4 cooperating with the guide groove are provided on both sides of the shell 3. Through the cooperation between the guide blocks 4 and the guide groove, the shell 3 can be more stable when being pulled out in the installation groove 2.

[0033] Furthermore, a dustproof net 14 is bonded to the inside of the air inlet hole 13, and the bottom shell 15 is fixed to the lower end of the fixing plate 12 by screws. The dustproof net 14 prevents dust and impurities from easily entering the inside of the bottom shell 15 through the air inlet hole 13, making the inside of the bottom shell 15 tidier.

[0034] There are two methods for assembling the bottom shell 15:

[0035] The first method is that the fixing plate 12 is fixed inside the groove 11 by screws. When the bottom shell 15 needs to be assembled, the screws on the fixing plate 12 can be operated.

[0036] The second type: the bottom shell 15 is threadedly connected to the gas stove body 1. In this case, when the bottom shell 15 needs to be assembled, the bottom shell 15 can be rotated. The structure is simple and the operation is convenient.

[0037] The housing 3 lacks a limiting structure in the mounting groove 2, which will cause the housing 3 to be installed loosely in the mounting groove 2. A positioning groove 18 is provided inside the mounting groove 2, and a card slot 20 is provided on the inner wall of the positioning groove 18. A positioning block 19 inserted into the positioning groove 18 is provided at the rear end of the housing 3. A cavity is provided on both sides of the positioning block 19, and a spring is provided inside the cavity. A card block 21 that cooperates with the card slot 20 is provided at one end of the spring. When the housing 3 is inserted into the mounting groove 2, the positioning block 19 is inserted into the inner wall of the positioning groove 18. At this time, the block 21 will enter the interior of the slot 20. Through the cooperation of the block 21 and the slot 20, a limiting effect can be provided to the positioning block 19 in the positioning slot 18, thereby providing a limiting structure for the shell 3 in the installation slot 2, which can make the shell 3 installed more firmly in the installation slot 2. When the pulling force provided to the shell 3 is greater than the elastic force of the spring, the block 21 can compress the spring, so that the shell 3 can be pulled out of the installation slot 2. There is no mandatory regulation on the length of the intake pipe 9, and the intake pipe 9 can be made of a rubber tube.

[0038] Furthermore, an electromagnet 22 is embedded inside the positioning groove 18, and an iron block 23 cooperating with the electromagnet 22 is embedded at the rear end of the positioning block 19. Specifically, a switch for controlling the electromagnet 22 can be installed at the front end of the shell 3 to energize and disconnect the electromagnet 22. When the electromagnet 22 is energized, a suction force is generated between the iron block 23, so that the shell 3 can be installed more firmly in the installation groove 2.

[0039] In the description of this article, it should be noted that relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
