[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-6 This utility model provides a gas sampling device for gas detection, including a housing body 1;

[0037] The suction mechanism 2 is located inside the storage body 1;

[0038] A storage component 3, which is connectable and detachable and located at the air outlet of the suction mechanism 2, includes an air inlet pipe 31, which is detachable and connectable and located at the air outlet of the suction mechanism 2; a first valve 32, located on the outside of the air inlet pipe 31; and an air storage tank 33, which is connectable and located at the lower end of the air inlet pipe 31.

[0039] In this embodiment, a gas sampling device for gas detection according to the present invention is provided. The suction mechanism 2 can extract the gas sampled from the outside, and then the suction mechanism 2 can send the extracted gas into the storage component 3, so that the storage component 3 can store the gas, thereby facilitating the delivery of the gas to the gas detection equipment for detection.

[0040] Furthermore, such as Figure 3 As shown, the preferred embodiment of the present invention includes a storage body 1, which further includes a sealing door 11 hinged to the front surface of the storage body 1; an air inlet 12 opened on the front surface of the sealing door 11; a door lock 13 located on the front surface of the sealing door 11; and two storage racks 14 symmetrically arranged on the inner side of the storage body 1.

[0041] In this embodiment, several preferred embodiments of the storage body 1 are provided. The storage rack 14 enables multiple storage components 3 to be placed inside the storage rack 14, thereby improving the convenience of carrying the storage components 3. The sealing door 11 can seal the storage body 1, thereby ensuring the safety of the storage components 3 and the suction mechanism 2 inside the storage body 1. Furthermore, under the action of the door lock 13, the sealing door 11 can be limited to the front surface of the storage body 1, thereby ensuring the stability of the sealing door 11 during use.

[0042] Furthermore, such as Figure 4 As shown, the suction mechanism 2 in the preferred embodiment of this utility model includes a mounting rod 21 located inside the housing body 1; a guide pipe 22 located on the lower end face of the mounting rod 21; a suction fan 23 located on the front end face of the guide pipe 22 and inside the air inlet 12; a connecting pipe 24 located on the lower end face of the guide pipe 22, and an air inlet pipe 31 detachably located on the outside of the connecting pipe 24; and two first limiting rods 25 symmetrically located on the outside of the connecting pipe 24.

[0043] In this embodiment, several preferred embodiments of the suction mechanism 2 are given. The suction fan 23 can draw in the outside air and send the drawn air into the air duct 22. Then the air in the air duct 22 will enter the air storage tank 33 through the air inlet pipe 31 connected to the connecting pipe 24, so that the air storage tank 33 can sample the air.

[0044] Furthermore, such as Figure 5-6As shown, the storage component 3 in the preferred embodiment of this utility model further includes two connecting plates 34 symmetrically arranged on the upper end face of the gas storage tank 33; two L-shaped holes 35 respectively and symmetrically opened on the outer side of the two connecting plates 34, and two first limiting rods 25 respectively located on the inner side of the two L-shaped holes 35; a gas outlet pipe 36 connected to the lower end face of the gas storage tank 33; a second valve 37 located on the outer side of the gas outlet pipe 36; and two second limiting rods 38 symmetrically arranged on the outer side of the gas outlet pipe 36.

[0045] Furthermore, the lower end of the first limiting rod 25 is located inside the short end of the L-shaped hole 35; the sealing ring is located inside the air inlet pipe 31, and the outer side of the air outlet pipe 36 is in contact with the inner side of the sealing ring. In this way, the sealing performance between the air inlet pipe 31 and the connecting pipe 24 and the air outlet pipe 36 can be improved under the action of the sealing ring.

[0046] Preferably, there are several storage components 3, and the several storage components 3 can be placed inside the storage rack 14.

[0047] Furthermore, the outer side of the gas tank 33 and the inner side of the storage rack 14 are interference-fitted, which improves the stability of the gas tank 33 when placed inside the storage rack 14.

[0048] This embodiment provides several preferred embodiments of the storage component 3. By sleeved the air inlet pipe 31 on the outside of the connecting pipe 24, and with the two first limiting rods 25 respectively located in the L-shaped holes 35 opened on the two connecting plates 34, and then rotating the air tank 33, the first limiting rods 25 can be located inside the short end of the L-shaped hole 35. In this way, under the action of the first limiting rods 25, the air tank 33 can be more stably set on the outside of the connecting pipe 24. Furthermore, the air inlet pipe 31 of another storage component 3 can be sleeved on the outside of the air outlet pipe 36 of the storage component 3, and the two second limiting rods 38 of the storage component 3 can be placed into the L-shaped holes 35 opened on the two connecting plates 34 of the other storage component 3. Then, the air tank 33 of the other storage component 3 can be rotated, so that the second limiting rods 38 can be located inside the short end of the L-shaped hole 35. In this way, multiple storage components 3 can be spliced ​​together and interconnected. Then, the first valve 32 and the second valve of the lowest storage component 3 can be connected. Valve 37 is in the open and closed states respectively. The first valve 32 and the second valve 37 of the other storage components 3 are both in the open state. In this way, the suction mechanism 2 can send the external gas into the gas storage tank 33 through the air inlet pipe 31 connected to the connecting pipe 24. Since the gas storage tanks 33 of multiple storage components 3 are interconnected, gas can be sent into multiple gas storage tanks 33 at the same time. This allows for simultaneous gas sampling, which not only improves the convenience of gas sampling but also improves the accuracy of gas detection. After sending gas into the gas storage tank 33 for a period of time, the first valve 32 and the second valve 37 of all storage components 3 can be closed. Then, the connected storage components 3 can be separated, thus completing the gas sampling. When the gas needs to be sent to the gas detection equipment for testing, the second valve 37 of the storage component 3 is opened, which releases the gas stored in the gas storage tank 33 into the gas detection equipment, allowing the gas detection equipment to detect the sampled gas.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
