Abstract
Description
Technical Field
[0001] This utility model relates to the field of air compressor technology, and more specifically to a combined structure for quantitative drainage of a dental air compressor. Background Technology
[0002] Dental air compressors on the market typically use either manual or timed drainage. Manual drainage requires regular checks, which is inconvenient and prone to internal corrosion due to human error if drainage is neglected for extended periods. Furthermore, high water levels and high humidity can lead to excessive moisture discharge from the air outlet, causing malfunctions. Timed drainage, on the other hand, is set to automatically drain at fixed intervals. However, even with low water levels, it can continue to discharge compressed air, potentially causing low pressure and affecting performance. Additionally, low pressure can trigger the pump to automatically restart, reducing its lifespan. Therefore, a design is needed that drains water only when the tank is empty and shuts off immediately when water is gone.
[0003] Insufficiency of existing technology: Both existing manual drainage and timed drainage methods have certain shortcomings and are not conducive to the long-term use of the air compressor. There is a need to provide a structure that can automatically detect the water level in the tank and determine whether drainage is required based on the water level. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a combined structure for quantitative drainage of a dental air compressor to solve the problems existing in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined structure for quantitative drainage of a dental air compressor, including an air tank, and further including: a support mechanism, an automatic drainage mechanism, a power mechanism, and an oil-water separation mechanism. The support mechanism is fixedly connected to the top of the air tank, and an automatic drainage mechanism is provided inside the air tank. The power mechanism is fixedly connected to the top of the support mechanism, and an oil-water separation mechanism is fixedly connected to one side of the power mechanism. The automatic drainage mechanism includes a one-way valve fixedly connected to the side of the air tank and an internal water inlet pipe. An inlet pipe is fixedly connected to the side of the one-way valve, and a quantitative drainage valve is fixedly connected to one end of the inlet pipe. A drainage pipe is fixedly connected to the bottom side of the quantitative drainage valve.
[0006] Furthermore, the quantitative drainage valve includes a water limiting pipe, the top end of which is fixedly connected to one end of the inlet pipe. A through water trough is opened inside the water limiting pipe, and a piston is installed at the bottom of the water trough. A spring is ringed around the side of the piston. A water storage tank is fixedly connected to the bottom end of the water limiting pipe. An upper liquid level sensor and a lower liquid level sensor are respectively installed on the upper and middle parts of the inner wall of the water storage tank. An outlet is provided on the side of the water storage tank. The outlet is slightly lower than the horizontal height of the lower liquid level sensor. A sealing gasket is provided inside the water storage tank at the same position as the opening at one end of the outlet.
[0007] Furthermore, a support plate is fixedly connected to the side of the water storage tank, and annular brackets are fixedly connected to both sides of the support plate. Diagonal bracing plates are fixedly connected to the long sides of the annular brackets at symmetrical positions. One side of the diagonal bracing plate is fixedly connected to the side of the gas storage tank through a fastener.
[0008] Furthermore, a motor is fixedly connected to the top of the support plate, and compressors are symmetrically arranged at both ends of the motor. An air valve is fixedly connected to the top of the compressor, and a connecting plate is fixedly connected to the side of the motor through a fixing plate.
[0009] Furthermore, an oil-water mixing chamber is fixedly connected to the side of the compressor on the motor side, an oil-water separation filter chamber is fixedly connected to the side of the oil-water mixing chamber, and an oil cup is fixedly connected to the bottom of the oil-water separation filter chamber.
[0010] Furthermore, end caps are fixedly connected to both ends of the gas storage tank, and supports are fixedly connected to the four corners of the bottom end of the gas storage tank.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. This utility model features an automatic drainage mechanism. Utilizing the pressure difference between the inside and outside of the tank, water inside the tank flows through the water inlet pipe at the bottom of the tank towards the one-way valve. After passing through the one-way valve, the water flows through the inlet pipe into the quantitative drainage valve. When the capacitance of the upper liquid level sensor inside the quantitative drainage valve changes due to water injection, it will open the sealing gasket of the quantitative drainage valve, allowing water to drain out of the equipment through the drain pipe. When the water level drops to the lower liquid level sensor, the capacitance changes, and the sealing gasket will automatically close. This facilitates automatic drainage of the air compressor and ensures that the pressure inside the tank does not leak out.
[0013] 2. This utility model, through the combined application of a one-way valve and a quantitative drain valve, achieves automatic drainage based on the water volume in the tank, which helps to increase the life of the pump head. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The combined structure for quantitative drainage of a dental air compressor involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Reference Figures 1 to 7This utility model provides a combined structure for quantitative drainage of a dental air compressor, including an air tank 1, and further including: a support mechanism 2, an automatic drainage mechanism 3, a power mechanism 4, and an oil-water separation mechanism 5. The support mechanism 2 is fixedly connected to the top of the air tank 1, and the automatic drainage mechanism 3 is provided inside the air tank 1. The power mechanism 4 is fixedly connected to the top of the support mechanism 2, and the oil-water separation mechanism 5 is fixedly connected to one side of the power mechanism 4. The automatic drainage mechanism 3 includes a one-way valve 301 fixedly connected to the side of the air tank 1 and an internal drain valve. Water pipe 302 and one-way valve 301 are fixedly connected to a water inlet pipe 303. One end of the water inlet pipe 303 is fixedly connected to a metering drain valve 304. The bottom side of the metering drain valve 304 is fixedly connected to a drain pipe 305. When there is a certain amount of water inside the gas storage tank 1, the pressure difference between the inside and outside of the tank will force the water inside the tank to flow through the water inlet pipe 302 toward the one-way valve 301. The one-way valve 301 only allows the water to flow in one direction. The water flows through the water inlet pipe 303 to the metering drain valve 304. The metering drain valve 304 automatically drains water according to the amount of water.
[0024] The quantitative drainage valve 304 includes a limiting pipe 3041, the top end of which is fixedly connected to one end of an inlet pipe 303. A through-flow water trough is formed inside the limiting pipe 3041, and a piston 3042 is installed at the lower part of the trough. A spring 3043 is annularly mounted on the side of the piston 3042. A water storage tank 3044 is fixedly connected to the bottom end of the limiting pipe 3041. An upper liquid level sensor 3045 and a lower liquid level sensor 3046 are respectively installed on the upper and middle parts of the inner wall of the water storage tank 3044. An outlet 3047 is provided on the side of the water storage tank 3044, slightly lower than the horizontal height of the lower liquid level sensor 3046. A sealing gasket 304 is provided inside the water storage tank 3044 at the same position as the opening at one end of the outlet 3047. 8. Water flows through the inlet pipe 303 to the limiting pipe 3041 of the quantitative drain valve 304. When the water pressure reaches a certain level, the piston 3042 will drop, and the water will flow through the limiting pipe 3041 into the water storage tank 3044. When the water level in the water storage tank 3044 reaches the upper liquid level sensor 3045, the sealing gasket 3048 will open, and the water will be discharged from the outlet 3047 through the drain pipe 305. The water will continue to be discharged. When the water level in the tank drops to a level that prevents the water from passing through the one-way valve 301, the water pressure will be insufficient to make the piston 3042 drop. The spring 3043 will reset the piston 3042, closing the limiting pipe 3041. The water level in the water storage tank 3044 will continue to drop. When the water level drops to the lower liquid level sensor 3046, the sealing gasket 3048 will close, stopping the drainage.
[0025] Among them, a support plate 201 is fixedly connected to the side of the water storage tank 3044, and annular brackets 202 are fixedly connected to both sides of the support plate 201. Diagonal bracing plates 203 are fixedly connected symmetrically to the long sides of the annular brackets 202. One side of the diagonal bracing plate 203 is fixedly connected to the side of the gas storage tank 1 via a fastener 204. A motor 401 is fixedly connected to the top of the support plate 201. Compressors 402 are symmetrically arranged at both ends of the motor 401. A gas valve 403 is fixedly connected to the top of the compressor 402. The side of the motor 401 is fixedly connected to the gas storage tank 1 via a fastener 204. A connecting plate 405 is fixedly connected to a fixed plate 404. An oil-water mixing chamber 501 is fixedly connected to the side of the compressor 402 on one side of the motor 401. An oil-water separation filter chamber 502 is fixedly connected to the side of the oil-water mixing chamber 501. An oil cup 503 is fixedly connected to the bottom of the oil-water separation filter chamber 502. The air is compressed by the compressor 402 to increase the pressure to the required level. Then the air passes through the oil-water separation mechanism 5 to remove impurities and oil vapor, ensuring that the output air is clean and oil-free. Finally, the pure compressed air is stored in the air storage tank 1.
[0026] Among them, the two ends of the gas storage tank 1 are fixedly connected with end caps 101, and the four corners of the bottom end of the gas storage tank 1 are fixedly connected with supports 102.
[0027] The working principle of this utility model is as follows: After the motor 401 starts, the compressor 402 compresses the air. Impurities and oil vapor in the air are removed through the oil-water mixing chamber 501 and the oil-water separation filter chamber 502, which are fixedly connected to the side of the compressor 402. The pure compressed air is stored in the air storage tank 1. Due to factors such as the condensation of moisture in the air and temperature changes during the compression process, moisture accumulates in the air storage tank 1. When the amount of water stored in the air storage tank 1 reaches a certain level, the pressure difference between the inside and outside of the tank will force the water in the tank to flow through the water inlet pipe 302 towards the one-way valve 301. The one-way valve 301 only allows water to flow in one direction. The water flows through the water inlet pipe 303 to the limit valve 304. When the water pressure in water pipe 3041 reaches a certain level, piston 3042 will descend, and water will flow through water limiting pipe 3041 into water storage tank 3044. When the water level in water storage tank 3044 reaches the upper liquid level sensor 3045, sealing gasket 3048 will open, and water will be discharged from outlet 3047 through drain pipe 305. Water will continue to be discharged. When the water level in the tank drops to a level that prevents water from passing through one-way valve 301, the water pressure will be insufficient to descend piston 3042. Spring 3043 will reset piston 3042, closing water limiting pipe 3041. The water level in water storage tank 3044 will continue to drop. When the water level drops to the lower liquid level sensor 3046, sealing gasket 3048 will close, stopping drainage.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
