[0026] Please see Figure 1 , Figure 2 As shown, this application embodiment provides a flow regulating device, which includes a main body 100 and an adjusting rod 104. The main body 100 has a cylindrical structure. One end of the main body 100 is provided with a connecting hole 103, and the other end of the main body 100 is provided with an air inlet 101. An air outlet 102 penetrating the main body 100 is also provided on the side wall of the main body 100. The adjusting rod 104 is connected to the connecting hole 103 and can be moved and adjusted within the main body 100.

[0027] The flow regulating device of this utility model has a simple overall structure. The flow rate of the gas path is adjusted by changing the position of the adjusting rod 104. The operation is simple and improves the convenience of adjusting the flow rate of the gas path.

[0028] According to some embodiments of this utility model, the flow regulating device further includes an air inlet pipe 105, which is inserted into the air inlet port 101. An air supply device is connected via the air inlet pipe 105 to allow gas to enter the flow regulating device.

[0029] According to some embodiments of this utility model, the flow regulating device further includes an outlet pipe 106, which has an L-shaped structure and is inserted into the outlet hole 102. The outlet pipe 106 is provided to facilitate the output of gas regulated by the flow regulating device.

[0030] According to some embodiments of this utility model, the side wall of the adjusting rod 104 is provided with an external thread 107, and the inner side wall of the main body 100 is provided with an internal thread 108. The adjusting rod 104 and the main body 100 are threadedly connected by the external thread 107 and the internal thread 108. Through this threaded connection, the position of the adjusting rod 104 within the main body 100 can be changed by rotating the adjusting rod 104, thereby achieving the adjustment effect.

[0031] According to some embodiments of the present invention, the adjusting rod 104 is provided with a first annular groove 109, and a first sealing ring 110 is sleeved inside the first annular groove 109.

[0032] According to some embodiments of the present invention, the adjusting rod 104 is provided with a second annular groove 111, and a second sealing ring 112 is sleeved inside the second annular groove 111.

[0033] By setting the first sealing ring 110 and the second sealing ring 112, the sealing performance of the adjusting rod 104 within the main body 100 is improved, thereby enhancing the adjusting effect of the adjusting rod 104.

[0034] According to some embodiments of this utility model, at least a portion of the adjusting rod 104 is exposed outside the main body 100. The portion of the adjusting rod 104 exposed outside the main body 100 is provided with a rotating part 113, which has a prism-shaped structure. The portion of the adjusting rod 104 exposed outside the main body 100 facilitates rotation by the operator. The rotating part 113 is used to connect a knob structure, making it convenient for the operator to rotate the adjusting rod 104.

[0035] According to some embodiments of the present invention, the adjusting rod 104 has a first state, a second state, and a third state. In the first state, one end of the adjusting rod 104 located inside the main body 100 blocks the vent 102. In the second state, one end of the adjusting rod 104 located inside the main body 100 partially blocks the vent 102. In the third state, one end of the adjusting rod 104 located inside the main body 100 avoids the vent 102.

[0036] In the first state, the adjusting rod 104 blocks the vent 102, preventing gas from flowing out of the vent 102. In the second state, the adjusting rod 104 partially blocks the vent 102, allowing a small amount of gas to flow out. By changing the position of the adjusting rod 104, the amount of the vent 102 blocked by the adjusting rod 104 is changed, thereby changing the gas flow rate output by the flow regulating device. In the third state, the adjusting rod 104 avoids the vent 102, at which point the gas flow rate output by the flow regulating device reaches its maximum value.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
