[0021] Embodiment 2 Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the specific improvements are as follows: both sides of the inner wall of the upper cylinder 101 are provided with limit plates 14, the inclined plates 9 are fixedly installed inside the upper cylinder 101 through the limit plates 14, and multiple inclined plates 9 are respectively arranged between the two limit plates 14 from top to bottom, and the bottoms of the inner sides of the two limit plates 14 are threadedly connected with hand bolts 15, and the threaded ends of the hand bolts 15 penetrate into the interior of the upper cylinder 101, and the hand bolts 15 are used to fix the limit plates 14; A convex plate 16 is fixedly connected to the bottom of the upper cylinder 101, and an L-shaped plate 17 is fixedly connected to the top of the lower cylinder 102.

After the plug rod 18 is pulled out, the mixer 1 can be easily disassembled, and the special-shaped channel 3 and the swirl plate 2 can be taken out from the lower cylinder 102. It is also convenient to screw the hand-tightening bolt 15 out of the limit plate 14, and the inclined plate 9 can be taken out of the upper cylinder 101 as a whole, so as to facilitate the cleaning of the interior of the mixer 1 and structures such as the special-shaped channel 3, the swirl plate 2 and the inclined plate 9, thereby reducing the generation of cleaning dead corners and achieving a better cleaning effect.

[0023] Embodiment 3 In conjunction with Example 1 and Example 2, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the specific improvements are as follows: the top of the upper cylinder 101 is connected to the air outlet pipe 19, the bottom and both sides of the lower cylinder 102 are connected to the air inlet pipe 20, and the outer side of the air inlet pipe 20 is provided with a gas flow sensor 21 for detecting the gas flow, so as to adjust the size of the air inlet 30 according to the detection result, and one side of the air inlet pipe 20 is fixedly connected to a frame 22, and a through groove is opened on the side of the frame 22 for facilitating the entry and exit of the connecting plate 23, and the interior of the frame 22 is provided with a connecting plate 23 through a gear assembly; The gear assembly includes a motor 24 fixed to the outside of the frame 22, the output end of the motor 24 is fixedly connected to a rotating rod 25 that rotates with the inner wall of the frame 22, and a gear 26 is fixedly connected to the surface of the rotating rod 25, and a toothed plate 27 is meshed on the top of the gear 26. A baffle 28 is fixedly connected to one side of the connecting plate 23 that passes through the inside of the air intake pipe 20, and the connecting plate 23 and the baffle 28 are combined to open or seal the air inlet 30, the top of the toothed plate 27 is fixed to the bottom of the connecting plate 23 and the baffle 28, a fixed plate 29 is fixedly connected to one side of the inner wall of the air intake pipe 20, and an air inlet 30 adapted to the baffle 28 is opened on the top of the fixed plate 29, a support rod 31 is fixedly connected to one side of the inner wall of the air intake pipe 20, and a movable groove 32 adapted to the support rod 31 is opened on one side of the baffle 28, and the support rod 31 and the movable groove 32 are set to support and limit the combination of the connecting plate 23 and the baffle 28.

[0024] Through the arrangement of the above structure, when the gas enters the mixer 1, the gear assembly drives the baffle 28 to reciprocate, which is convenient for adjusting the size of the air inlet 30, thereby being able to control the gas flow and effectively controlling the flow ratio of different gases.

[0025] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0026] When in use, different gases enter the mixer 1 through different air inlet pipes 20 respectively, the gas flow sensor 21 monitors the gas flow in real time, and drives the rotating rod 25 and the gear 26 to rotate by starting the motor 24, and the gear 26 drives the baffle 28 to reciprocate under the fixed plate 29 through the tooth plate 27, and the support rod 31 plays a role in supporting and stabilizing the baffle 28. When the baffle 28 moves back and forth, the size of the air inlet 30 can be adjusted, so as to control the gas flow; After multiple gases enter the mixer 1, they pass through the swirl plate 2, which guides the gases to produce a rotating motion. In the process of rotating and rising, different gases are caused to intertwine and mix with each other. After the gases are initially mixed, they enter the special-shaped channel 3. Through the design of the narrow mouth 4 and the wide mouth 5, multiple gases can be gathered or diffused. At the same time, when passing through the narrow mouth 4 and the wide mouth 5 in turn, the blades 7 are driven to rotate under the impact of the gas to further mix the gases. The surface of the blades 7 is also provided with multiple through holes 8, which can allow the gas to pass through and shear the mixed gas to improve the uniformity of the mixing. After the gas flows out of the special-shaped channel 3, it passes through multiple inclined plates 9 and the air outlet 10 in turn, collides with the gas, and further improves the uniformity of the mixing, so that the gas is fully contacted and mixed during the mixing process, and the mixing efficiency is improved. The gas after mixing is discharged through the outlet pipe 19; When not in use, the mixer 1 is laid on the ground, the motor 112 is started, and the threaded rod 113 is driven to rotate. Under the guidance of the slider 115, the clamping rod 114 moves on the threaded rod 113 into the sleeve 111, so that the clamping rod 114 moves out of the insertion rod 18, and then the insertion rod 18 is pulled out of the L-shaped plate 17 and the convex plate 16, and the mixer 1 can be disassembled, and then the special-shaped channel 3 and the swirl plate 2 can be pulled out of the lower cylinder 102, and the hand-tightening bolt 15 is screwed at the same time. After the hand-tightening bolt 15 is screwed out of the limit plate 14, the multiple inclined plates 9 can be taken out of the upper cylinder 101 as a whole, and the internal mixing components can be taken out separately, which is convenient for cleaning and has a better cleaning effect.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
