[0002] In modern industrial manufacturing, vacuum machines are widely used in the preparation and processing of liquid materials (such as adhesives and coatings). Their core purpose is to effectively reduce or eliminate residual bubbles in the material by removing gas from inside the container, thereby improving the density, uniformity, and long-term storage and use performance of the final product. In recent years, vacuum machines have continued to develop towards automation and intelligence, significantly improving the efficiency and ease of operation of degassing operations.

Existing vacuum machines only have one set of piston pumps, resulting in slow vacuuming speeds and poor sealing, making it difficult to guarantee the vacuuming effect and affecting the performance. Therefore, we have proposed a new type of vacuum machine. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A novel vacuum machine includes a cylinder 1, a top cover 2 mounted on the top of the cylinder 1, a sealing ring 1 between the cylinder 1 and the top cover 2, a display screen 21 fixedly connected to the top of the top cover 2, buttons fixedly connected to the surface of the display screen 21, a circuit board 22 mounted on the bottom of the top cover 2, the circuit board 22 including a control circuit, a connector and a USB socket, a buzzer 23 fixedly connected to the surface of the circuit board 22, a mounting hole 24 fixedly connected to the bottom of the top cover 2, a mounting bracket 3 mounted on the bottom of the top cover 2, a mounting hole 31 fixedly connected to the surface of the mounting bracket 3, mounting seats 32 fixedly connected to both sides of the mounting hole 31, a solenoid valve 33 fixedly connected inside one mounting seat 32, a valve inlet pipe 34 fixedly connected to the surface of the solenoid valve 33, and the other... A solenoid valve 2 35 is fixedly connected inside the side mounting base 32. A negative pressure exhaust pipe 36 is fixedly connected to the surface of the solenoid valve 2 35. A negative pressure exhaust port 37 and a suction port 38 are fixedly connected to the surface of the mounting bracket 3. A negative pressure sensor PCBA 39 is fixedly connected to the surface of the mounting bracket 3. A sealing ring 2 is provided at the bottom of the negative pressure sensor PCBA 39. A mounting hole 310 is fixedly connected to the surface of the mounting bracket 3. A connecting structure 4 is provided at the top of the mounting bracket 3. The connecting structure 4 includes a piston pump rubber bracket 41. Two sets of piston pump bodies 42 are fixedly connected to the surface of the piston pump rubber bracket 41. A piston pump through hole 43 is fixedly connected to the surface of one set of piston pump bodies 42. A piston pump is connected to a second connecting hole 44. A connecting pipe 45 is fixedly connected to the surfaces of the first connecting hole 43 and the second connecting hole 44. Another piston pump body 42 is fixedly connected to a third connecting hole 46. A tee 47 is fixedly connected to the surface of the third connecting hole 46. One end of the tee 47 is fixedly connected to a pump exhaust pipe 48. A one-way valve is fixedly connected to the surface of the pump exhaust pipe 48. The other end of the one-way valve is fixedly connected to a suction pipe 49. A solenoid valve 33, a second solenoid valve 35, and a connecting structure 4 are provided. The first solenoid valve 33 is connected to the piston pump body 42 through a valve inlet pipe 34. It can release the negative pressure on the valve inlet pipe 34 during vacuuming, preventing the piston pump body 42 from malfunctioning due to excessive negative pressure. The second solenoid valve 35 is connected to the negative pressure exhaust port 37 via the negative pressure exhaust pipe 36, which can release the negative pressure inside the cylinder 1. The two sets of piston pump bodies 42 are connected to each other via the connecting pipe 45, which can increase the pressure of the piston pump body 42 during vacuuming and improve the vacuuming effect. Through the one-way valve at the suction pipe 49, air can only be drawn out through the piston pump body 42 at the suction pipe 49, and gas cannot enter the cylinder 1 from the suction pipe 49 through the suction port 38, which improves the sealing performance. The vacuuming speed is fast and the sealing performance is good, which can ensure the vacuuming effect and avoid affecting the use effect. Anti-slip pad 11, display screen 21, buzzer 23 and negative pressure sensor PCBA 39 are set. The anti-slip pad 11 can increase the stability of the cylinder 1 when it is placed.To increase friction with the ground and prevent slipping due to shaking during use, a negative pressure sensor PCBA39 monitors the internal pressure of the cylinder 1 in real time, and displays the result on the display screen 21 via circuit board 22, providing a clear and intuitive view of the current pressure. When the pressure approaches a critical value, an alarm is triggered by buzzer 23, ensuring safety during use.

[0024] Furthermore, an anti-slip pad 11 is fixedly connected to the bottom of the cylinder 1. The anti-slip pad 11 is made of rubber. The anti-slip pad 11 can increase the stability of the cylinder 1 when it is placed and increase the friction between it and the ground to prevent it from slipping due to shaking during use.

[0025] Furthermore, four sets of mounting holes 24 are provided on the bottom circumference of the top cover 2, and four sets of mounting holes 310 are provided on the top circumference of the mounting bracket 3. The four sets of mounting holes 24 and the four sets of mounting holes 310 correspond to each other. The top cover 2 and the mounting bracket 3 are connected and installed together by bolts, mounting holes 24 and mounting holes 310, which facilitates the installation and disassembly of both and makes maintenance and repair more convenient.

[0026] Furthermore, the display screen 21, solenoid valve 1 33, solenoid valve 2 35, negative pressure sensor PCBA 39, and piston pump body 42 are all electrically connected to the circuit board 22. The circuit board 22 is electrically connected to an external power source. The bottom of the negative pressure sensor PCBA 39 passes through the mounting bracket 3, and the circuit board 22 is powered by an external power source. The control circuit on the circuit board 22 provides unified control of the display screen 21, solenoid valve 1 33, solenoid valve 2 35, negative pressure sensor PCBA 39, and piston pump body 42. The circuit board 22 is connected to other devices or power sources via a USB connector. The negative pressure sensor PCBA 39 monitors the pressure inside the cylinder 1 in real time. The sealing ring 2 ensures the seal between the negative pressure sensor PCBA 39 and the mounting bracket 3. The display screen 21 is operated via buttons on its surface.

[0027] Furthermore, the piston pump through hole 43 is connected to a set of piston pump bodies 42, and the piston pump connecting hole 44 and piston pump connecting hole 3 46 are connected to another set of piston pump bodies 42. The two sets of piston pump bodies 42 are connected in series through connecting pipe 45, and the two sets of piston pump bodies 42 are connected to each other through connecting pipe 45. This can increase the pressure of the piston pump body 42 when drawing a vacuum and increase the vacuuming effect. By installing the piston pump body 42 in the piston pump rubber bracket 41, vibration can be reduced when the piston pump body 42 is running.

[0028] Furthermore, the two ends of the suction pipe 49 are fixedly connected to the one-way valve and the suction port 38, respectively. The three ends of the tee 47 are fixedly connected to the solenoid valve 33, the one-way valve, and the piston pump connecting hole 46, respectively. The two ends of the negative pressure exhaust pipe 36 are fixedly connected to the negative pressure exhaust port 37 and the solenoid valve 35, respectively. The solenoid valve 33 can release the negative pressure on the valve inlet pipe 34 during vacuuming to avoid the piston pump body 42 from malfunctioning due to excessive negative pressure. The solenoid valve 35 can release the negative pressure inside the cylinder 1. When in use, the piston pump body 42 draws gas from the cylinder 1 through the air extraction port 38, enters the piston pump body 42 through the air extraction pipe 49, and then discharges it outward through the pump exhaust pipe 48. The one-way valve on the air extraction pipe 49 ensures that the gas can only be drawn out of the cylinder 1 by the action of the piston pump body 42, preventing gas from entering from here. When the piston pump body 42 is drawing gas, the one-way valve on the pump exhaust pipe 48 prevents external gas from entering. At the same time, when the piston pump body 42 is venting gas, the gas can be discharged from the pump exhaust pipe 48.

[0029] Furthermore, the pump exhaust pipe 48 is fixedly connected to the three-way valve 47 and the solenoid valve 33. One end of the pump exhaust pipe 48 is fixedly connected to the top of the solenoid valve 33. The solenoid valve 33 can release the negative pressure on the valve inlet pipe 34 when vacuuming, so as to avoid the situation where the piston pump body 42 cannot be used normally due to the large negative pressure.

[0030] Working principle: When in use, the liquid to be defoamed is placed inside the cylinder 1, and connected to the adapter via the USB connector on the top of the cover 2. The display screen 21 enters standby mode and automatically shuts off after ten minutes of inactivity. Operation is performed via the buttons on the display screen 21. Upon startup, one set of piston pump bodies 42, solenoid valve one 33, solenoid valve two 35, and negative pressure sensor PCBA 39 work together to begin drawing air out of the cylinder 1. After sixty seconds of operation, another set of piston pump bodies 42 starts working. To prevent excessive current from excessive starting current when both sets of piston pump bodies 42 start simultaneously, the adapter is protected against overcurrent. The pump bodies 42 are interconnected by connecting pipe 45, which can increase the pressure of the piston pump body 42 when drawing a vacuum and improve the vacuuming effect. Solenoid valve 33 can release the negative pressure on the valve inlet pipe 34 during vacuuming to avoid the piston pump body 42 from failing to work properly due to excessive negative pressure. The pressure inside the cylinder 1 is monitored in real time by negative pressure sensor PCBA39 and displayed on display screen 21 via circuit board 22. After the countdown ends, the pump stops working and the negative pressure inside the cylinder 1 is released by solenoid valve 35. After the pressure is released, the top cover 2 can be opened to take out the defoamed liquid.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
