Description

At present, mechanical vacuum pumps on the market generally have only one vacuum output source. In some specific places, when multiple vacuum output sources are required, it is necessary to equip multiple mechanical vacuum pumps at the same time, or use some relatively complex and large mechanical multi-source mechanical vacuum pumps.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] like Figures 1 to 4 As shown, an integrated vacuum generator described in the utility model includes an integrated air circuit board 1, a vacuum generator 2, a detection mechanism 3 and an adjustment mechanism 4. A main air flow channel 11 and a secondary air flow channel 12 are provided in the integrated air circuit board 1. One end of the secondary air flow channel 12 is connected to the main air flow channel 11, and the other end of the secondary air flow channel 12 is connected to the vacuum generator 2. The detection mechanism 3 and the adjustment mechanism 4 are arranged in the secondary air flow channel 12. The detection mechanism 3 is used to detect the amount of air flow flowing in the secondary air flow channel 12, and the adjustment mechanism 4 is used to adjust the amount of air flow flowing in the secondary air flow channel 12. The integrated air circuit board 1 has at least one vacuum generator 2, and the number of the secondary air flow channels 12, the detection mechanism 3 and the adjustment mechanism 4 is the same as the number of the vacuum generator 2.

[0026] The utility model realizes independent detection and adjustment of the air flow of each vacuum generator 2 by setting a detection mechanism 3 and an adjustment mechanism 4 in the secondary air flow channel 12 of each vacuum generator 2. It enables users to quickly adjust the negative pressure value and flow rate of different vacuum generators 2 according to the needs of different working environments, workloads or work objects. Whether it is necessary to increase or decrease the flow rate, it can be achieved through the adjustment mechanism 4, thereby improving the flexibility and adaptability of the integrated vacuum generator. At the same time, the flow rate of each vacuum generator 2 can be adjusted independently, avoiding the problem of the entire integrated vacuum generator being affected by excessive or insufficient flow of a certain vacuum generator 2. This design makes the entire integrated vacuum generator more stable and reliable, reduces the possibility of failure, and increases the service life of the integrated vacuum generator.

[0027] Further, refer to Figure 2 and Figure 3 As shown, the regulating mechanism 4 includes a movable chute 41 and a movable slider 42, wherein the movable chute 41 is connected to the secondary airflow channel 12, and the movable slider 42 is slidably disposed in the movable chute 41. Specifically, the movable slider 42 is slidably disposed in the movable chute 41, and by sliding the slider, the cross-sectional area of ​​the secondary airflow channel 12 can be effectively changed, thereby accurately regulating the amount of airflow flowing in the secondary airflow channel 12. This mechanical regulating method is intuitive and reliable, and can achieve continuous and stepless regulation of the flow rate, thereby improving the accuracy of flow regulation.

[0028] Further, refer to Figure 2 and Figure 3 As shown, the adjustment mechanism 4 also includes a rotating shaft 43, which is rotatably arranged in the movable chute 41, and the outer side of the rotating shaft 43 is provided with an external thread, and the movable chute 41 is provided with a rotating hole, and the inner side of the rotating hole is provided with an internal thread that matches the thread of the rotating shaft 43. Specifically, by arranging a rotatable rotating shaft 43 in the movable chute 41, and the outer side of the rotating shaft 43 is provided with an external thread, which matches the rotating hole provided with an internal thread in the movable chute 41, the position of the movable slider 42 in the chute is precisely adjusted by rotating the rotating shaft 43. This thread matching method makes the flow adjustment more continuous and smooth, and can achieve more precise fine-tuning, thereby improving the accuracy and stability of flow control. At the same time, since the adjustment of the rotating shaft 43 has the characteristics of high precision, high stability and easy operation, the integrated vacuum generator can adapt to more complex and changeable working environments and workloads.

[0029] Further, refer to Figure 2 and Figure 3 As shown, the regulating mechanism 4 also includes a rotating motor 44, and the output end of the rotating motor 44 is coaxially fixedly connected to the rotating shaft 43. The regulating mechanism 4 also includes a control terminal, and the control terminal is electrically connected to the rotating motor 44 and the detection mechanism 3. Specifically, through the control terminal, the user can conveniently remotely operate and control the regulating mechanism 4 without manually adjusting the slider or rotating the rotating shaft 43. At the same time, the control terminal can also display the current negative pressure value and flow data in real time to help users better understand the working status of the integrated vacuum generator. This operation method is not only simple and intuitive, but also improves the user experience. At the same time, the control terminal can adjust the operating status of the rotating motor 44 in real time according to the feedback data of the detection mechanism 3, so that the regulating mechanism 4 can respond to flow changes more quickly and make corresponding adjustments. In addition, by accurately controlling the rotation angle and speed of the rotating motor 44, the accuracy and stability of flow regulation can be further improved.

[0030] Further, refer to Figure 2 and Figure 3As shown, the detection mechanism 3 includes an airflow sensor 31, the detection end of the airflow sensor 31 is arranged in the secondary airflow channel 12, and the airflow sensor 31 is electrically connected to the control terminal. Specifically, the airflow sensor 31 can detect the airflow volume in the secondary airflow channel 12 in real time and accurately, convert the flow data into an electrical signal and transmit it to the control terminal. This enables the control terminal to grasp the current flow situation in real time and provide accurate data support for subsequent adjustment actions. At the same time, the airflow sensor 31 can not only detect the flow data, but also monitor abnormal conditions in the airflow channel, such as blockage, leakage, etc. When an abnormality occurs, the airflow sensor 31 will send a corresponding fault signal to the control terminal, so that the control terminal can issue an early warning in time and take corresponding diagnostic measures to improve the reliability and maintainability of the integrated vacuum generator.

[0031] Further, refer to Figure 2 and Figure 3 As shown, the regulating mechanism 4 also includes a sealing groove 45, which is arranged in the secondary airflow channel 12, and the sealing groove 45 is located opposite to the movable slide groove 41. Specifically, an effective sealing structure is formed by the cooperation between the sealing groove 45 and the sliding slider. When the sliding slider moves to the position of the sealing groove 45, its end can be tightly embedded in the sealing groove 45, thereby effectively blocking the secondary airflow channel 12 and preventing airflow leakage. At the same time, through the cooperation between the sliding slider and the sealing groove 45, the secondary airflow channel 12 is reliably closed. This makes it possible to quickly and accurately cut off the airflow channel when it is necessary to reduce or stop the airflow, thereby enhancing the stability and reliability of flow regulation.

[0032] Further, refer to Figure 2 and Figure 3 As shown, the regulating mechanism 4 also includes a sealing ring 46, which is arranged between the movable chute 41 and the movable slider 42. Specifically, by adding a sealing ring 46 between the movable chute 41 and the movable slider 42, the small gap between the movable chute 41 and the movable slider 42 can be effectively filled, thereby greatly enhancing the sealing performance. It can effectively prevent the airflow in the secondary airflow channel 12 from leaking from the gap between the movable chute 41 and the movable slider 42, ensuring the precise control of the flow rate and the efficient operation of the integrated vacuum generator. At the same time, the sealing ring 46 not only improves the sealing performance, but also reduces the friction and wear between the movable chute 41 and the movable slider 42 to a certain extent. This helps to reduce the maintenance frequency of the integrated vacuum generator, extend the service life of the integrated vacuum generator, and improve the overall economic benefits. Secondly, by enhancing the sealing performance, the noise and vibration caused by airflow leakage are reduced, the stability and quietness of the operation of the integrated vacuum generator are improved, thereby enhancing the user experience. In addition, reducing airflow leakage also helps to reduce potential safety risks.
