Description

Technical fields:

[0001] This invention relates to the field of lubrication systems, and specifically to an atomizing oil injection device and an atomizer for the device. Background technology:

[0002] Oil injectors are common components in equipment lubrication systems. Their main function is to atomize and spray lubricating oil into the corresponding working mechanism to reduce friction during operation and extend the service life of the equipment.

[0003] Currently, the atomizer of traditional fuel injectors is installed inside the fuel tank. Because the fuel tank has a large volume, high air pressure and a large amount of fuel are required for atomization before the fuel can reach the lubrication point. Due to the severe atomization, the oil mist fills the entire fuel tank and diffuses into the air, causing a certain amount of waste and endangering personal safety. Therefore, traditional fuel tanks have high requirements for airtightness, which makes manufacturing difficult, increases production costs, and poses a risk of explosion due to excessive air pressure during atomization.

[0004] Specifically, see the appendix. Figure 1 and attached Figure 2 As shown, a traditional fuel injector includes an oil cup 81, an atomizer 2, an oil suction nozzle 82, an oil suction chamber 12, a fuel nozzle 11, a first air intake pipe 31, a second air intake pipe 83, an aluminum oil suction pipe 84, a copper oil suction pipe 85, and an oil guide pipe 86. The entire fuel injector is mounted on the top of an oil tank container and forms a seal around the container. Its working principle is as follows: The aluminum suction tube 84 is used to introduce oil from the tank into the oil cup 81. High-speed airflow is introduced into the aluminum suction tube 84 through the second air intake pipe 83, thereby generating negative pressure to draw oil from the tank upward into the oil cup 81. The copper suction tube 85 connects the oil cup 81 and the suction chamber 12. The increase in air pressure in the tank forces the oil in the oil cup 81 into the suction chamber 12. The first air intake pipe 31 introduces high-pressure airflow into the atomizer 2, thereby generating negative pressure to draw oil from the suction chamber 12 into the atomizer 2 through the oil guide pipe 86. The oil is then dispersed and atomized in the atomizer 2 and sprayed through the nozzle 11 to each working mechanism. Therefore, the atomizer 2 works directly inside the tank, which causes a large amount of oil mist to fill the tank, further changing the pressure inside the tank. The oil mist will also continuously diffuse outside the tank with the airflow, resulting in a certain amount of waste.

[0005] In view of the above, the inventors propose the following technical solution. Summary of the Invention:

[0006] The first technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an atomizing oil spraying device.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the atomizing oil spraying device includes: an oil spray nozzle, an atomizing chamber connected to the oil spray nozzle, an atomizer installed in the atomizing chamber and connected to a first air inlet pipe, an oil suction chamber for supplying oil to the atomizer, and an oil supply device for supplying oil to the oil suction chamber. The atomizer and the oil suction chamber are connected by an oil suction pipe, and the oil suction chamber and the oil supply device are connected by an oil supply pipe.

[0008] Furthermore, in the above technical solution, a flow stabilizer for regulating flow rate is installed on the oil supply pipe.

[0009] Furthermore, in the above technical solution, the atomizer includes a connector for connecting the first air inlet pipe and the oil suction pipe, and an atomizing block disposed on the connector, the atomizing block being located directly in front of the air outlet of the connector.

[0010] Furthermore, in the above technical solution, the atomizing block is formed with a first atomizing groove and a second atomizing groove facing different directions, and a first connecting hole is formed between the first atomizing groove and the second atomizing groove. The first connecting hole is directly opposite the air outlet, and the diameter of the first connecting hole is smaller than that of the air outlet.

[0011] Furthermore, in the above technical solution, the communicating vessel is provided with a first channel that is linearly connected to the air outlet and connected to the first air inlet pipe, and a second channel that is perpendicular to the first channel and connected to the oil suction pipe. The first air inlet pipe is installed and connected to the first channel through a first connecting nozzle, and the oil suction pipe is installed and connected to the second channel through a second connecting nozzle.

[0012] Furthermore, in the above technical solution, the feeding device is a pulse pump, the oil inlet of the pulse pump is immersed in oil, and a flow stabilizer for adjusting the flow rate is installed on the oil supply pipe.

[0013] Furthermore, in the above technical solution, the fuel injector, the oil suction chamber, and the atomizing chamber are all installed on the oil cup head. The oil suction pipe is connected to the bottom of the oil suction chamber through a third connecting nozzle and is connected to the upper end of the oil suction chamber. An oil sight cap is installed on the upper end of the oil suction chamber.

[0014] Furthermore, in the above technical solution, the oil cup head is also provided with an oil filling port, which is located next to the oil sight cap, and the oil cup head is installed on the oil tank.

[0015] Furthermore, in the above technical solution, a plurality of the fuel injectors are installed on the oil cup head, and the fuel injectors are evenly distributed in a circumferential shape on the oil cup head.

[0016] Furthermore, in the above technical solution, an air filter for providing high-speed airflow to the first air intake pipe is provided on one side of the oil cup head, and a third channel for connecting the air filter is formed on one side of the oil cup head. The first air intake pipe is installed and connected to the third channel through a fourth connecting nozzle.

[0017] The second technical problem to be solved by the present invention is to provide an atomizer for the above-mentioned atomizing oil injection device.

[0018] The atomizer for the atomizing oil spraying device includes: a connector for connecting an external air passage and an oil passage, and an atomizing block disposed on the connector. The connector has an air outlet, and the external air passage and oil passage are connected and sprayed out through the air outlet. The atomizing block is formed with a first atomizing groove and a second atomizing groove facing different directions. A first connecting hole is formed between the first atomizing groove and the second atomizing groove. The first connecting hole is directly opposite the air outlet, and the diameter of the first connecting hole is smaller than that of the air outlet.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0020] 1. In this invention, by installing the atomizer inside the atomization chamber, the oil mist generated by the atomizer cannot diffuse into the fuel tank, thus preventing the oil mist from diffusing out of the fuel tank into the air, reducing unnecessary waste, and protecting the personal safety of workers. Secondly, by installing the atomizer inside the atomization chamber, the high-speed airflow flows directly from the atomization chamber through the nozzle, no longer entering the fuel tank. Therefore, no pressurization occurs inside the fuel tank, preventing the fuel tank from exploding due to excessive pressure. This also significantly reduces the airtightness requirements of the fuel tank, lowers the difficulty of the fuel tank manufacturing process, and reduces production costs.

[0021] 2. In this invention, a pulse pump is used to gradually pump oil through the oil supply pipe to the oil suction chamber, so that the oil supply is stable and not affected by the pressure change in the oil tank. This ensures that the oil volume in the oil suction chamber is in dynamic balance, so that the amount of oil drawn into the atomizer by the first air inlet pipe through the oil suction pipe remains constant, and the amount of oil mist produced by atomization remains constant.

[0022] 3. The atomizer in this invention uses dual atomization, which results in better atomization effect. Attached image description:

[0032] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0033] See Figures 3 to 9 The image shows an atomizing oil spraying device, characterized by comprising: an oil spray nozzle 11, an atomizing chamber 7 communicating with the oil spray nozzle 11, an atomizer 2 installed in the atomizing chamber 7 and connected to a first air intake pipe, an oil suction chamber 12 for supplying oil to the atomizer 2, and an oil supply device for supplying oil to the oil suction chamber 12. The atomizer 2 and the oil suction chamber 12 are connected by an oil suction pipe 32, and the oil suction chamber 12 and the oil supply device are connected by an oil supply pipe 33. By installing the atomizer 2 in the atomizing chamber 7, the oil mist generated by the atomizer 2 cannot diffuse into the oil tank, preventing oil mist from diffusing out of the oil tank into the air, thereby reducing unnecessary waste and protecting the personal safety of workers. Secondly, the atomizer 2 is installed inside the atomizing chamber 7, so that the high-speed airflow flows directly from the atomizing chamber 2 through the nozzle 11 and no longer enters the fuel tank. Therefore, the fuel tank will not be pressurized, avoiding the fuel tank from exploding due to excessive air pressure. It also greatly reduces the airtightness requirements of the fuel tank, reduces the difficulty of fuel tank processing, and reduces production costs.

[0034] A flow stabilizer 5 for regulating flow rate is installed on the oil supply pipe 33. By installing the flow stabilizer 5 on the oil supply pipe 33, the flow rate of the pulse pump 4 can be adjusted by controlling the flow rate of the oil supply pipe 33, while also ensuring that the oil supply rate is constant each time.

[0035] The atomizer 2 includes a connector 21 for connecting the first air inlet pipe 31 and the oil suction pipe 32, and an atomizing block 22 disposed on the connector 21. The atomizing block 22 is located directly in front of the air outlet 211 of the connector 21. High-speed airflow is injected into the atomizer 2 through the first air inlet pipe 31, creating a negative pressure in the connector 21 to draw oil from the oil suction chamber 12 into the atomizer 2. The oil then hits the atomizing block 22 with the high-speed airflow, forming an oil mist. The oil mist then flows out from the nozzle 11 with the airflow and sprays onto the working mechanism for lubrication, reducing friction between parts and increasing the service life of the equipment.

[0036] The atomizing block 22 is formed with a first atomizing groove 221 and a second atomizing groove 222 facing different directions. A first connecting hole 223 is formed between the first atomizing groove 221 and the second atomizing groove 222. The first connecting hole 223 is directly opposite the air outlet 211, and the diameter of the first connecting hole 223 is smaller than that of the air outlet 211. By using a double-layered atomizing block 22 with two atomizing grooves, the first atomizing groove 221 and the second atomizing groove 222 are connected by a first connecting hole 223. The first connecting hole 223 is positioned directly at the air outlet 211 and is smaller than the air outlet 211. This allows a high-speed airflow from the air outlet 211 to carry a portion of the oil, which then hits the first atomizing groove 211 to generate oil mist. The remaining oil, carried by the airflow, passes through the first connecting hole 223 and hits the second atomizing groove 222 to generate oil mist. This increases the atomization volume, ensuring all the oil is atomized. There is no need to reserve a return oil channel in the atomizer 2, and it can produce finer oil mist particles that adhere to the lubrication points with the airflow and can enter smaller gaps for lubrication, resulting in better lubrication. In contrast, traditional injector atomizers cannot completely convert oil into oil mist and require a channel for oil to return to the fuel tank in the atomizer.

[0037] The communicating vessel 21 is provided with a first channel 212 that is linearly connected to the air outlet 211 and the first air inlet pipe 31, and a second channel 213 that is perpendicular to the first channel 212 and connected to the oil suction pipe 32. The first air inlet pipe 31 is connected to the first channel 212 via a first connecting nozzle 311, and the oil suction pipe 32 is connected to the second channel 213 via a second connecting nozzle 321. The second channel 213 is perpendicular to the first channel 212, so that when airflow passes through the first channel 212, it creates a negative pressure on the second channel 213, thereby drawing oil from the oil suction chamber 12 into the first channel 212 through the oil suction pipe 32 and allowing it to flow with the airflow.

[0038] The feeding device is a pulse pump 4, with its inlet 41 immersed in oil. A flow stabilizer 5 for adjusting the flow rate is installed on the oil supply pipe 33. By using the pulse pump 4 to gradually pump oil through the oil supply pipe 33 to the oil suction chamber 12, the oil supply is stabilized and unaffected by pressure changes in the oil tank. This ensures that the oil volume in the oil suction chamber 12 is in dynamic equilibrium, thereby keeping the amount of oil drawn into the atomizer 2 by the first air inlet pipe 31 through the oil suction pipe 32 constant each time, and keeping the amount of oil mist produced by atomization constant.

[0039] The fuel injector 11, the oil suction chamber 12, and the atomizing chamber 7 are all mounted on the oil cup head 1. The oil suction pipe 32 is connected to the bottom of the oil suction chamber 12 via a third connecting nozzle 322 and to the upper end of the oil suction chamber 12. A sight cap 121 is installed on the upper end of the oil suction chamber 12. By opening the sight cap 121, the oil level in the oil suction chamber 12 can be observed to determine whether the fuel injector is working properly. At the same time, it is possible to observe whether the oil supply of the pulse pump 4 is stable and whether it meets the current lubrication requirements, so as to adjust the flow regulator 5 to change the oil supply in the future.

[0040] The oil cup head 1 is also provided with an oil inlet 13, which is located next to the oil sight cap 121. The oil cup head 1 is installed on the oil tank.

[0041] The oil cup head 1 is equipped with a plurality of oil nozzles 11, and the oil nozzles 11 are evenly distributed in a circumferential shape on the oil cup head 1. The oil cup head 1 is also provided with two lugs 14.

[0042] An air filter 6 is provided on one side of the oil cup head 1 to provide high-speed airflow to the first air intake pipe 31. A third channel is formed on one side of the oil cup head 1 to connect to the air filter 6. The first air intake pipe 31 is connected to the third channel via a fourth connecting nozzle 312. The air filter 6 filters out the high-speed airflow generated by the air compressor, ensuring that the airflow does not contain impurities and guaranteeing the quality of the high-speed airflow.

[0043] Traditional spray-type oilers operate on a negative pressure spray principle. Before normal oil spraying, the sprayer housing must be filled with a mixture of compressed air and grease at a certain pressure. For example, a typical housing volume is 2L. Each time the machine is stopped and started, 2L of compressed air is lost. The oil tank of this invention does not require inflation; only the 0.02L carburetor chamber requires gas. Under the same stop-and-start conditions, this invention can save 90% of the wasted compressed air compared to existing technologies. Furthermore, the number of stop-and-start cycles varies greatly depending on the weaving material, with some exceeding 100 cycles per day. Based on this calculation, assuming a company has 100 knitting machines * 100 stop-and-start cycles * 2L * 0.9 = 18,000m³ / day could be saved. 3 Compressed air.

[0044] In summary, the working principle of this invention is as follows: First, sufficient oil is added to the oil tank, submerging the oil inlet 41 of the pulse pump 4 in the oil; then, the pulse pump 4 pumps the oil into the oil suction chamber 12 through the oil supply pipe 33, so that a certain amount of oil is stored in the oil suction chamber 12; then, a high-speed airflow is sprayed into the atomizer 2 through the first air inlet pipe 31. Under the action of the high-speed airflow, the atomizer 2 generates negative pressure, drawing the oil from the oil suction chamber 12 through the oil suction pipe 32, and hitting the atomizing block 22 with the airflow, thereby generating tiny oil mist; then, after the oil mist is formed in the atomizing chamber 7, it flows out through the nozzle 11 with the airflow, and finally sprays and adheres to the lubrication point.

[0045] By adopting the above solution, the oil is mixed with compressed gas using an electronic pump, making the oil quantity adjustment and control of the moving parts more intuitive, convenient, and scientific. This reduces lubricant waste, saves energy and is environmentally friendly, and improves weaving quality.

[0046] In terms of environmental protection: it greatly reduces the waste of lubricating oil and compressed air, achieving energy conservation and environmental protection.

[0047] In terms of improving weaving quality: Electronic pumps can precisely control the amount of oil and gas mixed, avoiding the instability caused by various factors in modern products that rely on gas flowing through pipes to deliver oil, such as changes in air pressure or oil level in the tank, which can lead to poor oil-gas mixing. Excessive oil-gas mixture concentration will contaminate the woven fabric, affecting quality and wasting lubricating oil; insufficient oil will result in inadequate lubrication of moving parts, causing damage, and in severe cases, leading to excessive heat or machine seizure.

[0048] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of the present invention.
