Description

Technical Field

[0001] The utility model belongs to the technical field of injection devices, and in particular relates to an ejector. Background Art

[0002] An ejector is a device used to accelerate and eject a fluid into a jet, and is commonly used in various industrial and scientific applications. Its main function is to accelerate a fluid (liquid or gas) to high speed and release it through a nozzle to produce a jet with specific properties and applications. The invention and application of ejectors provide an important technical means for improving industrial automation and production efficiency. Through the application of ejectors, many industrial production processes can be automated and precisely controlled, greatly improving production efficiency and product quality.

[0003] Disinfectants are usually introduced when disinfecting water. Spraying disinfectants into water through an ejector can quickly kill bacteria, viruses and other microorganisms in the water, thereby effectively eliminating pathogens in the water and improving the disinfection effect. The ejector can effectively disperse the disinfectant evenly into the water, allowing it to fully contact the target substance in the water, thereby achieving a better disinfection effect. However, when adding, the water in the pipe must be at normal pressure. If the pipe water is greater than 0.1Mpa, the water will be pressed to the ejector water inlet and flow to the disinfection purification device, causing equipment corrosion or electrical damage.

[0004] In summary, the existing ejectors have the problem that water easily flows back. Utility Model Content

[0005] In view of this, the utility model provides an ejector, which can solve the problem of easy backflow of water in the existing ejector.

[0006] The utility model is achieved in this way:

[0007] The utility model provides an ejector, comprising a water inlet pipe, an air inlet pipe, a disinfection and purification device, a mixing chamber and a water outlet pipe, wherein one end of the water inlet pipe and the air inlet pipe are respectively fixedly connected to the mixing chamber, the water outlet pipe is fixedly connected below the mixing chamber, the water inlet pipe is used to deliver water into the mixing chamber, the disinfection and purification device is fixedly connected to the other end of the air inlet pipe, the water outlet pipe is used to discharge mixed liquid, wherein a self-adjusting structure is provided in the air inlet pipe, and the self-adjusting structure is used to prevent backflow of water.

[0008] The technical effects of an ejector provided by the utility model are as follows: by setting a water inlet pipe, high-pressure water can be continuously delivered to provide power for the ejector, and negative pressure is formed in the mixing chamber to attract the disinfectant in the air inlet pipe to mix with the water flow; by setting an air inlet pipe, the introduction of additional gas can increase the kinetic energy of the ejector, improve the injection speed and efficiency; by setting a disinfection and purification device, the oxidation effect of the jet can be enhanced, which can help remove pollutants in the environment and improve the quality of air and water. By setting a water outlet pipe, the dependence on and intervention of personnel can be reduced. This reduces operating costs and reduces the risk of potential problems caused by human errors. At the same time, the self-adjusting structure can prevent water backflow from contacting the disinfection and purification device.

[0009] On the basis of the above technical solution, an ejector of the utility model can also be improved as follows:

[0010] Wherein, a limiting ring is fixedly connected in the air intake pipe, and the limiting ring is arranged above the self-adjusting structure.

[0011] Furthermore, the self-adjusting structure includes a spring and a sealing member, one end of the spring is fixedly connected to the inner wall of the air intake duct, and the other end of the spring is fixedly connected to the sealing member.

[0012] Furthermore, the number of the springs is two, and the two springs are arranged in an eight-shaped shape.

[0013] Furthermore, the size of the sealing member is smaller than the size of the inner wall of the air intake pipe, and the size of the sealing member is larger than the size of the inner ring of the limiting ring.

[0014] Furthermore, the angle between the water inlet pipe and the air inlet pipe is a right angle.

[0015] Furthermore, the angle between the water inlet pipe and the water outlet pipe is a right angle.

[0016] Furthermore, a rebound base is sleeved on the other end of the water inlet pipe, and the rebound base is fixedly connected to the water inlet pipe.

[0017] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting a rebound base, it can be expanded and contracted under the impact of water flow, thereby maintaining the stability of the negative pressure value.

[0018] Compared with the prior art, the beneficial effects of the ejector provided by the utility model are: by setting a water inlet pipe, high-pressure water can be continuously delivered to provide power for the ejector; by setting a disinfection and purification device, the oxidation effect of the ejector can be enhanced. This reduces operating costs and reduces the risk of potential problems caused by human errors. At the same time, the self-adjusting structure can prevent water from flowing back and contacting the disinfection and purification device. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] During use, water flows through the rebound base 17 and the water inlet pipe 10 in turn into the mixing chamber 13; when the inflowing water flow is less than 2kg, the water flows directly out from the water outlet pipe 14; when the inflowing water flow is greater than 2kg, negative pressure is generated in the mixing chamber 13, and the substances produced by the disinfection and purification device 12 continue to flow downward, and the compression spring 151 drives the seal 152 to move downward and smoothly enters the mixing chamber 13 through the air inlet pipe 11 and the limit ring 16 to mix with the water flow and flow out from the water outlet pipe 14; when the inflowing water flow continues to decrease to less than 2kg, the internal and external pressures gradually balance, the disinfection and purification device 12 stops working, and the spring 151 rebounds to drive the seal 152 to reset and block the limit ring 16 so that the disinfectant no longer flows into the mixing chamber 13; if there is a tendency for the water flow to flow to the air inlet pipe 11, the spring 151 is driven to extend, and the seal 152 blocks the limit ring 16 to prevent the water flow from flowing to the disinfection and purification device 12.

[0027] Among them, in the above technical solution, a limit ring 16 is fixedly connected in the air intake pipe 11 , and the limit ring 16 is arranged above the self-adjusting structure 15 .

[0031] Furthermore, in the above technical solution, the size of the sealing member 152 is smaller than the size of the inner wall of the air intake pipe 11 , and the size of the sealing member 152 is larger than the size of the inner ring of the limiting ring 16 .

[0035] A rebound device is arranged inside the rebound base 17, and the rebound device can drive the rebound base 17 to extend and retract.

[0036] Specifically, the principle of the utility model is: when in use, the water flows through the rebound base 17 and the water inlet pipe 10 in turn into the mixing chamber 13; when the inflowing water flow is less than 2kg, the water flows directly out from the water outlet pipe 14; when the inflowing water flow is greater than 2kg, a negative pressure is generated in the mixing chamber 13, and the disinfectant produced by the disinfection and purification device 12 continues to flow downward, and the compression spring 151 drives the seal 152 to move downward and smoothly enters the mixing chamber 13 through the air inlet pipe 11 and the limit ring 16 to mix with the water flow and flow out from the water outlet pipe 14; when the inflowing water flow continues to decrease to less than 2kg, the internal and external pressures are gradually balanced, the disinfection and purification device 12 stops working, and the spring 151 rebounds to drive the seal 152 to reset and block the limit ring 16 so that the disinfectant no longer flows into the mixing chamber 13; if there is a tendency for the water flow to flow to the air inlet pipe 11, the spring 151 is driven to extend, and the seal 152 blocks the limit ring 16 to prevent the water flow from flowing to the disinfection and purification device 12.
