[0001] This utility model relates to the field of atomizing pump technology, and in particular to an atomizing pump with an adjustment mechanism. Background Technology

[0002] In industrial production, atomizing pumps are frequently used to atomize media such as adhesives and lubricants for spraying. Existing atomizing valves typically use high-pressure gas to drive a reciprocating motion of a striker, opening and closing the nozzle to break the media into atomized particles for spraying. However, these devices usually have the following problems: First, the stroke of the striker is often fixed, making it impossible to flexibly adjust according to the viscosity of different media or the required atomization precision, resulting in poor adaptability; second, the adjustment mechanism is prone to loosening due to vibration during equipment operation, affecting process stability; finally, the traditional atomizing gas flow channel design is simple, unable to form vortices or perform secondary shaping, limiting the control over atomization effect and spray shape.

[0003] Therefore, there is an urgent need for an atomizing pump with adjustable striker stroke, stable operation, and excellent atomization effect. Utility Model Content

And an atomizing needle, which is disposed in the needle assembly cavity, with a through medium output channel in the middle, and an airflow output channel formed between its outer side wall and the inner side wall of the needle assembly cavity, and its lower end is tapered. The first air intake channel is connected to the lower part of the stroke cavity, the first high-pressure gas channel is connected to the airflow output channel, and the second high-pressure gas channel is connected to the external gas output channel; the lower end of the valve body striker is inserted into the upper end of the medium output channel and blocks or opens it.

[0005] Preferably, the stroke adjustment mechanism includes: Adjust the mounting base and fix it to the upper end of the atomizing pump body. It has an internal thread groove on its inner side and a fitting groove around its upper circumference. The adjusting rod is fitted onto the adjusting mounting base, and its outer side wall is provided with an external thread groove that mates with the internal thread groove. Its lower end abuts against the pneumatic piston. An adjusting cap is fixedly mounted on the upper end of the adjusting rod; A tensioning pin is provided on the adjusting cap; A tension spring is fitted onto the adjusting cap to press the tension pin into the mating groove.

[0006] Preferably, an air guide groove is provided on the upper side of the atomizing needle, and the air guide groove is located at the connection between the first high-pressure gas channel and the airflow output channel.

[0007] Preferably, the air guide groove is a vertical groove, used to allow the airflow to enter the airflow output channel vertically.

[0008] Preferably, the air guide groove is an inclined groove, used to make the airflow form a vortex and enter the airflow output channel.

[0009] Preferably, the lower end of the external gas output channel is inclined toward the atomizing needle.

[0010] Preferably, the axes of the stroke cavity, the medium channel, the valve body striker, the pneumatic piston, the needle assembly cavity, and the atomizing needle are all on the same straight line.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this solution achieves atomized injection of the medium by driving and controlling the movement of the atomizing pin using gas. The atomizing pump body forms the basic framework of the entire device, with complex internal channels and cavities. The stroke cavity accommodates the pneumatic piston and provides it with space to move. The first air inlet channel guides high-pressure gas from the valve opening inlet to the lower part of the stroke cavity, pushing the pneumatic piston upward against the force of the piston spring. The valve body atomizing pin, fixed to the lower end of the pneumatic piston, rises accordingly, thereby opening the medium output channel at the center of the atomizing needle, allowing the medium to flow out from the medium inlet through the medium channel. When the pneumatic piston rises to expose the exhaust port, the gas in the cavity is discharged, the pressure drops rapidly, and the elastic force of the piston spring pushes the pneumatic piston to drive the valve body atomizing pin to quickly descend and reset, resealing the medium output channel, completing one injection cycle. Continuous input of control gas enables pulse injection.

[0014] Secondly, the atomizing sleeve in this solution can be adapted to the specifications of the atomizing needle to meet different customer needs. Furthermore, the inclination angle of the airflow output channel inside the atomizing sleeve and the external gas output channel can be set in different sizes to achieve atomization effects with different widths.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0024] like Figures 1 to 6 As shown, an atomizing pump with an adjustment mechanism mainly includes an atomizing pump body 1, a stroke adjustment mechanism 2, a pneumatic piston 3, a valve body striker 4, a piston spring 5, an atomizing sleeve 6, and an atomizing needle 7.

[0025] The atomizing pump body 1 has a stroke cavity 11, a first air inlet channel 12, a medium channel 13, a first high-pressure gas channel 14, and a second high-pressure gas channel 15. Correspondingly installed on the atomizing pump body 1 are a valve-opening air inlet 16 communicating with the first air inlet channel 12, a medium inlet 17 communicating with the medium channel 13, a first high-pressure gas connector 18 communicating with the first high-pressure gas channel 14, and a second high-pressure gas connector 19 communicating with the second high-pressure gas channel 15. An exhaust port is also provided within the stroke cavity 11.

[0026] The stroke adjustment mechanism 2 is located above the atomizing pump body 1. The pneumatic piston 3 is slidably disposed within the stroke cavity 11. The valve body striker 4 is fixedly installed at the lower end of the pneumatic piston 3. The piston spring 5 is installed between the stroke adjustment mechanism 2 and the pneumatic piston 3.

[0027] The atomizing sleeve 6 is installed on the lower side of the atomizing pump body 1. A needle assembly cavity is centrally located on its inner side, and an external gas output channel 61 is located on its outer side. The atomizing needle 7 is located in the needle assembly cavity, with a through medium output channel 71 in its middle. Its outer wall and the inner wall of the needle assembly cavity form an airflow output channel 72. The lower end of the atomizing needle 7 is tapered.

[0028] The first air intake channel 12 connects to the lower part of the stroke cavity 11, and is used to introduce high-pressure gas to push the pneumatic piston 3 upward. The first high-pressure gas channel 14 connects to the airflow output channel 72, and is used to provide the main airflow required for atomization. The second high-pressure gas channel 15 connects to the external gas output channel 61, and is used to provide the auxiliary forming airflow. The lower end of the valve body striker 4 is inserted into the upper end of the medium output channel 71, and its up-and-down movement can block or open the medium output channel 71.

[0029] Preferably, the stroke adjustment mechanism 2 includes an adjustment mounting base 21, an adjustment rod 22, an adjustment cap 23, a tensioning pin 24, and a tensioning spring 25. The adjustment mounting base 21 is fixedly mounted on the upper end of the atomizing pump body 1, with an internal threaded groove on its inner side and a mating groove around its upper circumference. The adjustment rod 22 is fitted onto the adjustment mounting base 21, with an external threaded groove on its outer wall that mates with the internal threaded groove, and its lower end abuts against the pneumatic piston 3. The adjustment cap 23 is fixedly mounted on the upper end of the adjustment rod 22. The tensioning pin 24 is mounted on the adjustment cap 23. The tensioning spring 25 is sleeved on the adjustment cap 23, pressing the tensioning pin 24 into the mating groove. Rotating the adjustment cap 23 drives the adjustment rod 22 to move up and down, thereby precisely limiting the upward endpoint of the pneumatic piston 3 and achieving stepless adjustment of the striker stroke. The engagement of the tension pin 24 with the matching groove provides a clear adjustment damping feel and sound, and effectively prevents the mechanism from rotating and loosening due to equipment vibration.

[0030] Preferably, an air guide groove 73 is provided on the upper side of the atomizing needle 7, and the air guide groove 73 is located at the connection between the first high-pressure gas channel 14 and the airflow output channel 72. The air guide groove 73 can be designed as a vertical groove, so that the airflow enters the airflow output channel 72 vertically downward; or it can be designed as an inclined groove, so that the high-pressure gas forms a swirling flow before entering the airflow output channel 72, thereby performing more thorough shearing of the medium and obtaining a finer atomization effect.

[0031] Preferably, the lower end of the external gas output channel 61 is inclined toward the atomizing needle 7. This auxiliary airflow can reshape and guide the atomized medium ejected from the atomizing needle 7 to meet the process requirements of different spraying shapes and ranges.

[0032] Preferably, it also includes a striker limiting sleeve 8. The striker limiting sleeve 8 is fixedly installed inside the atomizing pump body 1 and below the pneumatic piston 3, and the valve body striker 4 passes through the striker limiting sleeve 8. The striker limiting sleeve 8 guides and limits the movement of the valve body striker 4, ensuring the linear accuracy of its movement. At the same time, the sliding sealing fit between it and the valve body striker 4 improves the airtightness of the lower part of the stroke cavity 11.

[0033] Preferably, the axes of the stroke cavity 11, the medium channel 13, the valve body striker 4, the pneumatic piston 3, the needle assembly cavity, and the atomizing needle 7 are all on the same straight line. This coaxiality design ensures smooth movement of each component and reliable sealing, reducing the risk of uneven wear and leakage.

[0034] Preferably, the atomizing pump body 1 is further provided with a second air intake channel 121 and a valve-closing air intake port 122 connected to the second air intake channel 121. The second air intake channel 121 is connected to the upper part of the stroke cavity 11. Through this gas path, high-pressure gas can be introduced into the upper part of the stroke cavity 11, which assists the piston spring 5 in pushing the pneumatic piston 3 to quickly move downward to close the valve port, further improving the response frequency and closing reliability of the spray valve.

[0035] In this solution, the atomizing sleeve 6 can be adapted to the specifications of the atomizing needle 7 to meet different customer needs. Furthermore, the inclination angles of the inner airflow output channel 72 and the outer gas output channel 61 of the atomizing sleeve 6 can be set to different sizes to achieve atomization effects with different widths.

[0036] Working principle: This scheme achieves atomized injection of the medium by driving and controlling the movement of the impact pin with gas. The atomizing pump body 1 forms the basic framework of the entire device, with complex channels and cavities machined inside. The stroke cavity 11 is used to accommodate the pneumatic piston 3 and provide its movement space. The first air inlet channel 12 guides the high-pressure gas from the valve opening air inlet 16 to the lower part of the stroke cavity 11, pushing the pneumatic piston 3 to move upward against the force of the piston spring 5. The valve body impact pin 4, fixed to the lower end of the pneumatic piston 3, rises accordingly, thereby opening the medium output channel 71 in the center of the atomizing needle 7, allowing the medium to flow out from the medium inlet 17 through the medium channel 13. When the pneumatic piston 3 rises to expose the exhaust port, the gas in the cavity is discharged, the pressure drops rapidly, and the elastic force of the piston spring 5 pushes the pneumatic piston 3 to drive the valve body impact pin 4 to quickly move downward to reset, re-sealing the medium output channel 71, completing one injection cycle. Continuous input of control gas can achieve pulse injection.

[0037] The atomization process is assisted by two high-pressure gas streams. The first stream of gas enters through the first high-pressure gas connector 18, passes through the first high-pressure gas channel 14, and reaches the gas guide groove 73 on the upper part of the atomizing needle 7. The gas guide groove 73 can be inclined, such as... Figure 3 As shown, the gas forms a high-speed swirling flow and enters the airflow output channel 72, which is formed by the outer wall of the atomizing needle 7 and the inner cavity of the needle assembly. This swirling flow closely adheres to the medium flowing out from the medium output channel 71, shearing and breaking it into fine mist particles. The second gas enters from the second high-pressure gas connector 19, passes through the second high-pressure gas channel 15, and enters the outer gas output channel 61 outside the atomizing sleeve 6. The outlet of this channel is inclined towards the center, and the ejected gas envelops, concentrates, and directionally guides the atomized particle cloud, thereby controlling the shape and range of the spray.

[0038] The stroke adjustment mechanism 2 operates on the principle of threaded transmission: rotating the adjusting cap 23 causes the adjusting rod 22 to screw into or out of the adjusting mounting seat 21, thereby changing the height position of its lower end face in the stroke cavity 11. This lower end face determines the final upward position of the pneumatic piston 3. Therefore, the raising and lowering of the adjusting rod 22 directly changes the opening stroke of the valve body striker 4, achieving precise control of the medium flow rate. The tension spring 25 presses the tension pin 24, causing it to engage in the matching groove of the adjusting mounting seat 21, producing a noticeable damping sensation and a "click" sound. This facilitates the operator's perception of the adjustment amount and firmly locks the current position, preventing loosening.

[0039] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
