[0027] In the description of the present utility model, the terms "second" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "second" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0028] A major problem faced by existing vacuum sealers during the vacuuming process is that if the packaged items contain liquid or have a high water content, too much liquid is easily extracted together, resulting in incomplete sealing or poor sealing effect.

[0029] Reference Figure 1-4 As shown, a vacuum sealer with pressure-reducing stable wet extraction comprises:

[0030] A vacuum chamber 2 is arranged inside the main body 1, and a vacuum bag 3 whose opening is inserted into the vacuum chamber 2;

[0031] A monitoring component 4, a blowing component 5, a main control board 6, a vacuum pump 7, and a switching component 8 are arranged in the main body 1, wherein the monitoring component 4 is located on one side of the vacuum bag 3, and the vacuum pump 7 / blowing component 5 is connected to the vacuum chamber 2 through the switching component 8;

[0032] The main control board 6 is electrically connected to the detection component, the blowing component 5, the vacuum pump 7, and the switching component 8;

[0033] The vacuum pump 7 cooperates with the vacuum chamber 2 to form a negative pressure state, and the gas inside the vacuum bag 3 is extracted. The liquid inside the vacuum bag 3 flows through the preset area 9, and the monitoring component 4 identifies and feeds back to the main control board 6. Through the cooperation of the main control board 6 and the switching component 8, the vacuum pump 7 is switched to the blowing component 5 to transport gas toward the vacuum chamber 2, so that the liquid inside the vacuum bag 3 retreats.

[0034] By setting the monitoring component 4 and the switching component 8 in the vacuum chamber 2, and cooperating with the vacuum pump 7 and the blowing component 5. During the vacuuming process, the monitoring component 4 monitors the liquid situation in the vacuum bag 3 in real time. Once it is detected that the liquid is extracted and approaches the opening of the vacuum bag 3, the main control board 6 switches to the blowing mode through the switching component 8, blows part of the gas back to the vacuum chamber 2, and adjusts the negative pressure inside the vacuum chamber 2. The reduced negative pressure will cause the liquid inside the vacuum bag 3 to retreat and prevent the liquid from being extracted. It can effectively prevent the liquid from entering the vacuum pump 7 and the sealing area, ensure the integrity and effect of the sealing, and improve the sealing quality and reliability of the equipment.

[0035] The main body 1 includes a lower body 11 and a cover 12 rotatably mounted on one side of the lower body 11 , and the cover 12 rotatably covers the lower body 11 to form a vacuum chamber 2 inside.

[0036] The vacuum bag 3 is provided with a sealing portion 31 near the opening side;

[0037] The main body 1 further includes a sealing assembly 10 disposed inside the main body 1 , and the sealing assembly 10 abuts against the sealing portion 31 .

[0038] Among them, the sealing assembly 10 generally includes a heating bar: used to heat the sealing part 31 of the vacuum bag 3 to melt and bond it together, thereby achieving sealing. Pressure strip: works with the heating bar to ensure that the sealing part 31 can fit tightly when heated to ensure the firmness of the seal. Temperature sensor: used to monitor the temperature of the heating bar to ensure that the heating temperature is within an appropriate range to avoid overheating or underheating. Cooling system: after the sealing is completed, the sealing is quickly solidified by cooling the heating bar and the sealing part 31 to increase the sealing effect. These components work together to ensure that the sealing part 31 of the vacuum bag 3 can be quickly and firmly sealed after the vacuuming is completed, avoiding problems such as incomplete sealing or poor sealing.

[0039] Since the sealing assembly 10 is provided in every vacuum sealing machine and is not the focus of this solution, it will not be described in detail.

[0040] In order to accurately prevent liquid from entering the sealing portion 31 that is in contact with the sealing assembly 10 , the preset area 9 is located in the area of ​​the sealing portion 31 facing outward.

[0041] Since this area is close to the sealing portion 31, the location of liquid outflow can be detected more accurately and timely, and identification and feedback can be performed before the liquid reaches the sealing portion 31, so that measures can be taken quickly to prevent the liquid from affecting the sealing effect.

[0042] By monitoring this area, the blowing mode can be switched to before the liquid approaches the sealing portion 31, and the liquid can be retracted to prevent the liquid from entering the sealing portion 31. This effectively reduces the impact of the liquid on the sealing quality and ensures the firmness and integrity of the sealing.

[0043] Preventing liquid from entering the sealing portion 31 can not only ensure the quality of each seal, but also reduce the damage of the liquid to the internal components of the sealing machine, thereby extending the service life of the equipment and improving the reliability of the sealing machine.

[0044] In order to detect the dynamics of the liquid more sensitively, the monitoring component 4 includes an infrared sensor 41, which is installed on the cover 12 / lower body 11 close to the outside of the vacuum chamber 2. The infrared sensor 41 monitors the outer portion of the sealing portion 31.

[0045] The infrared sensor 41 has high sensitivity and can detect the presence of liquid quickly and accurately, ensuring timely feedback of information and preventing liquid from entering the sealing portion 31 .

[0046] The infrared sensor 41 is non-contact, which means that it does not come into direct contact with the liquid, thereby avoiding the problem of the sensor being damaged or contaminated by contact with the liquid and improving the durability and reliability of the sensor.

[0047] Installing the infrared sensor 41 on the cover 12 or the lower body 11 outside the vacuum chamber 2 can better protect the sensor from the high pressure and liquid environment in the vacuum chamber 2, thereby extending its service life.

[0048] By monitoring the portion of the sealing portion 31 facing outward, the infrared sensor 41 can accurately identify the location where the liquid flows out, and take measures before the liquid reaches the sealing portion 31 to prevent the liquid from entering the sealing area, thereby ensuring the sealing effect.

[0049] Through efficient and accurate liquid monitoring and feedback mechanism, it can effectively prevent the interference of liquid on the sealing process, ensure the integrity and quality of the seal, and improve the overall performance of the sealing machine.

[0050] The blowing assembly 5 includes a blowing motor 51 , and the blowing motor 51 is electrically connected to the main control board 6 .

[0051] The main function of the air blowing motor 51 in the vacuum sealer is to remove liquid or impurities by blowing air, thereby ensuring the cleanliness and dryness of the sealing portion 31, thereby improving the quality and effect of the sealing.

[0052] The blowing motor 51 generates airflow, and the blowing motor 51 is electrically connected to the main control board 6. Accurate blowing operation can be achieved through the control of the main control board 6, and the blowing process can be performed in time in conjunction with the monitoring of the sensor.

[0053] In this embodiment, a micro motor is used, which is small in size and easy to install inside the device without taking up too much space. The micro motor usually has low power consumption, and has low energy consumption while maintaining an effective blowing function.

[0054] The micro motor is small in size and can be easily integrated into the equipment without taking up too much space. It is light in weight and has little impact on the overall weight of the equipment, which is conducive to the lightweight design of the equipment.

[0055] Usually, the noise is low during operation, which improves the silent effect of the device and enhances the user experience. In addition, the micro motor has a fast response speed and can quickly start blowing when liquid is detected to prevent liquid from entering the sealing portion 31.

[0056] The shell of the air blowing motor 51 adopts a commercially available motor. For example, a commonly seen micro air blowing motor 51 on the market is Nidec24H700S001:

[0057] Size: 24mm diameter, voltage: 12V, power: 1.2W, features: high efficiency, low noise, low power consumption, suitable for a variety of small household appliances and industrial equipment.

[0058] Mabuch i FA-130RA: Size: 20mm diameter, 15mm thickness, Voltage: 3-6V, Power: 0.5W, Features: Widely used in toys, power tools, household appliances and other fields, with high reliability and long life.

[0059] Maxon 110191: Size: 22mm diameter, Voltage: 24V, Power: 2.4W, Features: high efficiency, precision control, commonly used in medical equipment and precision instruments.

[0060] In this embodiment, a micro motor can be selected as the blowing motor 51, and a suitable model can be selected according to specific needs to realize the blowing function, thereby ensuring the stable operation and efficient sealing effect of the vacuum sealing machine.

[0061] The switching assembly 8 includes a solenoid valve 81 , which is electrically connected to the main control board 6 , and the blowing motor 51 is connected to the vacuum chamber 2 via the solenoid valve 81 .

[0062] By controlling the electromagnetic valve 81 through the main control board 6, the start and stop time of the blowing motor 51 can be accurately adjusted to achieve accurate control of the blowing process. This control method can flexibly adjust the intensity and duration of the blowing according to actual needs to ensure that the liquid at the sealing part 31 is completely removed.

[0063] The solenoid valve 81 can open the blowing channel only when needed according to the detected liquid conditions, thereby reducing unnecessary blowing operations, reducing energy consumption, and improving the energy utilization efficiency of the equipment.

[0064] By controlling the opening and closing of the electromagnetic valve 81, the air blowing motor 51 can be prevented from running continuously for a long time, thereby reducing wear and tear and extending the service life of the motor. At the same time, this arrangement can also prevent liquid from flowing back to the air blowing motor 51, protecting the motor from liquid erosion.

[0065] The entire system is automatically controlled by the main control board 6 without manual intervention, which greatly improves the automation and intelligence level of the equipment, making user operation easier and providing a better experience.

[0066] Among them, the main control board 6 is an IC board.

[0067] The liquid and impurities in the sealing portion 31 can be effectively removed through the precisely controlled blowing process, ensuring that the sealing area is dry and clean, thereby improving the sealing quality and sealing effect and preventing sealing failure or leakage.

[0068] In order to more accurately determine the liquid flow dynamics, the monitoring component 4 also includes a visual sensor 42, which is installed on the outer side of the cover 12 close to the vacuum chamber 2. The visual sensor 42 monitors the vacuum bag 3 toward the outer side of the main body 1.

[0069] The combination of the visual sensor 42 and the infrared sensor 41 can provide more comprehensive monitoring data. The visual sensor 42 is good at capturing detailed images, while the infrared sensor 41 can detect in low light or obstructed conditions. The two complement each other and improve the accuracy and reliability of monitoring.

[0070] The visual sensor 42 can accurately detect the position, shape and liquid overflow of the vacuum bag 3, while the infrared sensor 41 can detect temperature changes or other physical characteristics, thereby providing double verification to ensure the correctness of the state of the vacuum bag 3 during the sealing process.

[0071] The infrared sensor 41 can quickly respond to the approach of an object or temperature changes, while the visual sensor 42 provides detailed image data. The combination of the two can more quickly feedback abnormal conditions of the vacuum bag 3, and the main control board 6 can make timely adjustments to improve the response speed and sealing efficiency of the equipment.

[0072] A higher level of automatic monitoring and control can be achieved through the coordinated work of the visual sensor 42 and the infrared sensor 41. The main control board 6 can perform a comprehensive analysis based on the data provided by the two sensors, automatically adjust the sealing parameters, reduce manual intervention, and improve production efficiency.

[0073] Dual sensor monitoring can detect potential problems earlier, such as liquid overflow or abnormal position of vacuum bag 3, and issue alarms or take measures in time to prevent equipment failure or operating accidents and protect the safety of equipment and operators.
