[0030] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Reference Figure 1 As shown, this utility model provides an exhaust structure, including a water tank 10, a water pump 20, and a pipe assembly 30, wherein:

[0032] The water tank 10 provides an expansion chamber, which causes the liquid flow rate to drop sharply, giving the bubbles time to rise; the water tank 10 is provided with an exhaust port 11, which is located above the highest liquid level, allowing the gas to continuously overflow to the outside.

[0033] The water pump 20 provides power to the venting structure to extract liquid from the water tank 10, allowing the liquid to flow within the pipe assembly 30.

[0034] The piping assembly 30 includes a first pipe 31, a second pipe 32, and a third pipe 33. The first pipe 31 is connected to the water tank 10; one end of the second pipe 32 is connected to the water tank 10, and the other end of the second pipe 32 is connected to one end of the water pump 20; the third pipe 33 is connected to the other end of the water pump 20. The water pump 20 acts as the circulation power source, drawing the initially degassed liquid out of the water tank 10 and returning it to the system, establishing a closed-loop circulation.

[0035] The first pipe 31 has an inlet 311 and an outlet 312. A puncturing element 50 is provided inside the outlet 312 to puncture the air bubbles delivered from the outlet 312 of the first pipe 31. Preferably, the puncturing element 50 is located in the area of ​​the first pipe 31 where the liquid is about to leave the pipe opening and the air bubbles have not yet diffused, so as to increase the probability of contact with the air bubbles.

[0036] The above embodiment, by setting a puncturing element 50 at the outlet 312 of the first pipe 31, can mechanically puncture the air bubbles before the liquid enters the water tank 10, so that the gas is released quickly and automatically discharged through the exhaust port 11 of the water tank 10. It eliminates the need for frequent manual pipe checks and gas release, realizes continuous, efficient, and unattended online degassing, and has a simple exhaust method, which improves exhaust efficiency.

[0037] In one feasible implementation, refer to Figure 3 as well as Figure 4 As shown, the piercing element 50 extends at least partially into the first pipe 31. The piercing element 50 has a receiving cavity 51, with an opening 52 formed on the side near the water inlet 311. Several protruding structures 53 and several through-holes 54 are provided on the inner wall of the piercing element 50 facing the opening 52. Each protruding structure 53 has a cutting edge 55 on the side facing the opening 52. Using the cutting edge 55 of the protruding structure 53, the liquid film is pierced instantly upon contact with the air bubble, releasing the gas inside the bubble. The liquid is then discharged into the water tank 10 through the drains 54.

[0038] In the embodiments provided in this application, reference is made to Figure 1 and Figure 2As shown, an adjustment component 40 is provided on the first pipe 31 and / or the third pipe 33. The function of the adjustment component 40 is to accelerate the flow speed of the liquid in the pipe assembly 30 to increase the exhaust speed. The adjustment component 40 includes a positioning member 41 and an adjustment member 42. The positioning member 41 is connected to the first pipe 31 and / or the third pipe 33, and the adjustment member 42 is disposed on the positioning member 41. The adjustment member 42 can move along a preset path. When the adjustment member 42 moves to the end of the preset path, the adjustment member 42 presses against the first pipe 31 or the third pipe 33. As the adjustment member 42 continues to move, the force exerted by the adjustment member 42 on the first pipe 31 and / or the third pipe 33 gradually increases.

[0039] The preset path is a movement path in which the adjusting member 42 squeezes the first pipe 31 or the third pipe 33, so that the cross-sectional area of ​​the first pipe 31 or the third pipe 33 gradually decreases.

[0040] According to the exhaust requirements, the adjusting component 40 is first fixed to the position on the first pipe 31 or the third pipe 33 by the positioning component 41. After the position is determined, the adjusting component 42 is controlled to move along the preset path. When the adjusting component 42 is at the beginning of the preset path, the adjusting component 42 has no contact with the first pipe 31 or the third pipe 33, or there is no force between the adjusting component 42 and the first pipe 31 or the third pipe 33, or the adjusting component 42 applies a small force to the first pipe 31 or the third pipe 33. During the movement of the adjusting component 42 to the end of the preset path, the adjusting component 42... 2. The force applied by the adjusting member 42 to the first pipe 31 or the third pipe 33 gradually increases, which gradually increases the degree of compression of the first pipe 31 or the third pipe 33. As a result, the cross-sectional area of ​​the corresponding pipe section of the first pipe 31 or the third pipe 33 gradually decreases. Under the condition that the liquid flow rate in the exhaust structure is the same, the narrower the pipe section through which the liquid flows, the faster the liquid flow rate, thereby accelerating the flow speed of the liquid in the exhaust structure. When the accelerated liquid flows through the air blockage space, it can quickly carry away the air bubbles, thereby improving the exhaust efficiency.

[0041] The preset path can be a linear path or a non-linear path, and can be set according to actual needs and exhaust structure.

[0042] In one feasible embodiment, the adjusting member 42 is provided with a first sliding portion 421, and the positioning member 41 is provided with a first sliding engagement portion 411. The first sliding portion 421 and the first sliding engagement portion 411 can form a sliding engagement, so that the adjusting member 42 can move along a preset path. After the adjusting assembly 40 is positioned on the first pipe 31 or the third pipe 33 by the positioning member 41, the sliding engagement of the first sliding portion 421 and the first sliding engagement portion 411 can be used to make the adjusting member 42 slide on the positioning member 41, so that the adjusting member 42 moves along the preset path in a sliding manner.

[0043] Furthermore, the first sliding part 421 includes a slider 4211, and the first sliding engagement part 411 is a groove 4111 provided on the positioning member 41. The slider 4211 can move in the groove 4111. The extension direction of the groove 4111 has a preset angle with the extension direction of the first pipe 31 or the third pipe 33. That is, relative to the first pipe 31 or the third pipe 33, the groove 4111 is provided on the positioning member 41 in an inclined posture.

[0044] The chute 4111 has a first end and a second end. The first end of the chute 4111 is further away from the first pipe 31 or the third pipe 33. The starting end of the preset path is the position of the first end of the chute 4111, and the ending end of the preset path is the position of the second end of the chute 4111. The preset path is the path along which the slider 4211 slides from the first end of the chute 4111 to the second end of the chute 4111. As the slider 4211 moves along the preset path, the distance between the slider 4211 and the first pipe 31 or the third pipe 33 gradually decreases, and the sliding force on the first pipe 31 or the third pipe 33 gradually increases, so that the cross-sectional area of ​​the first pipe 31 or the third pipe 33 gradually decreases, thereby increasing the flow rate of the liquid flowing through the first pipe 31 or the third pipe 33.

[0045] When the slider 4211 slides to a position where the cross-sectional area of ​​the pipe can meet the flow rate requirements of the liquid, the position of the slider 4211 needs to be fixed so that the liquid can maintain a stable flow rate. In the embodiment provided in this application, a limiting part 412 is also provided in the groove 4111, and a limiting fitting part 422 is provided on the slider 4211. The limiting part 412 and the limiting fitting part 422 can form a limiting fit to restrict the movement of the slider 4211 in the groove 4111.

[0046] After the slider 4211 moves to a suitable position, the slider 4211 is fixed in the groove 4111 by the limiting part 412 and the limiting mating part 422, thereby fixing the position of the adjusting member 42 and keeping the cross-sectional area of ​​the first pipe 31 or the third pipe 33 at a suitable size, thereby keeping the liquid flow rate stable.

[0047] Since the liquid flow rate needs to be adjusted according to the bubble situation, the slider 4211 needs to be able to be fixed at any position in the groove 4111 for easy adjustment. In one feasible embodiment, the limiting part 412 is provided along the extending direction of the groove 4111. When the limiting mating part 422 abuts against the limiting part 412, the slider 4211 can be restricted from continuing to move. The limiting parts 412 are arranged in the extending direction of the groove 4111, so that when the slider 4211 moves to any position in the groove 4111, the limiting mating part 422 can abut against the limiting part 412 to fix the slider 4211 in the corresponding position.

[0048] Specifically, the limiting part 412 is a limiting groove 4121 located at the top of the slide 4111, and the limiting mating part 422 is a limiting block 4221 located on the slider 4211. The limiting block 4221 can be inserted into the limiting groove 4121 so that the limiting part 412 and the limiting mating part 422 form a limiting fit. After the slider 4211 moves to a suitable position, the slider 4211 is released, so that the limiting block 4221 is inserted into the limiting groove 4121, thereby fixing the position of the slider 4211.

[0049] Furthermore, the limiting groove 4121 includes multiple limiting grooves 4121, which are sequentially arranged on the top of the slide groove 4111. That is, along the extension direction of the slide groove 4111, multiple limiting grooves 4121 are sequentially arranged on the top of the slide groove 4111. When the slider 4211 moves to any position, the limiting block 4221 can correspond to the limiting groove 4121, so that the limiting block 4221 can be embedded in the corresponding limiting groove 4121, so that the slider 4211 can be fixed at any position of the slide groove 4111.

[0050] In order to improve the applicability of the exhaust structure and enable the adjustment component 40 to be fixed at any position of the first pipe 31 or the third pipe 33, in the embodiments provided in this application, the positioning member 41 includes a second sliding part, which allows the positioning member 41 to reciprocate along the axial direction of the first pipe 31 or the third pipe 33.

[0051] Under the action of the second sliding part, the positioning member 41 can reciprocate along the axial direction of the first pipe 31 or the third pipe 33, thereby driving the adjusting member 42 to move synchronously, and can adjust the pipe cross-sectional area at any position on the first pipe 31 or the third pipe 33, so as to facilitate the installation of the adjusting component 40 in any convenient position.

[0052] The second sliding part can be a through hole provided on the positioning member 41. The adjusting component 40 is sleeved on the first pipe 31 or the third pipe 33 through the through hole. The through hole can realize the reciprocating movement of the positioning member 41 in the axial direction of the first pipe 31 or the third pipe 33.

[0053] The second sliding part may also be other structures or components that enable the positioning member 41 to move in the axial direction of the first pipe 31 or the third pipe 33, and there is no limitation here.

[0054] The aforementioned positioning element 41 is an integral structure. In other embodiments, the positioning element 41 may also be a split structure. In one feasible implementation, the positioning element 41 includes a first positioning block and a second positioning block. The first positioning block and the second positioning block can be joined together radially along the first pipe 31 or the third pipe 33 so that the positioning element 41 is fitted onto the first pipe 31 or the third pipe 33. The surface shapes of the first positioning block and the second positioning block are respectively adapted to the shape of the outer peripheral surface of the first pipe 31 or the third pipe 33, so that after the first positioning block and the second positioning block are joined together, the first pipe 31 or the third pipe 33 can be fitted into the space enclosed by the first positioning block and the second positioning block, thereby ensuring the stability of the position of the adjusting component 40 on the pipe.

[0055] Based on the above embodiments, the exhaust principle of the exhaust structure of this application is as follows: First, the position of the adjusting component 40 on the first pipe 31 or the third pipe 33 is determined, the adjusting slider 4211 is moved in the slide groove 4111 to a suitable position corresponding to the required flow rate of the liquid, and then the slider 4211 is released so that the limiting block 4221 on the slider 4211 is embedded in the corresponding limiting groove 4121, thereby fixing the position of the slider 4211.

[0056] Next, the water pump 20 is started to draw liquid from the bottom of the water tank 10. The liquid flows into the water tank through the second pipe 32 and the third pipe 33 and then into the water tank through the outlet 312 of the first pipe 34. Since the puncturing element 50 is set in the water tank 10 near the outlet 312 of the first pipe 31, the air bubbles can be mechanically punctured before the liquid enters the water tank 10, so that the gas is released quickly and automatically discharged through the exhaust port 11 of the water tank 10. There is no need for frequent manual pipe checking and gas release, realizing continuous, efficient, unattended online degassing. The exhaust method is simple and the exhaust efficiency is high.

[0057] The above description of the structure, features and effects of this utility model is based on the embodiments shown in the drawings. The above are only preferred embodiments of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings.
