[0002] A vacuum sealer is a device used to package products such as food, medicine, and electronic components in plastic bags or aluminum foil bags. It forms a vacuum by pumping out the air inside the bag and then heat-seals the bag opening, thereby extending the shelf life of the product and preventing problems such as oxidation, mildew, and decay.

[0003] The existing thermal sensitive temperature control component of the vacuum sealer requires multiple connection lines, which increases the complexity of the internal structure. The complex thermal sensitive temperature control system increases the production cost. The numerous lines not only make assembly and maintenance difficult but also increase the probability of failures.

[0004] Moreover, due to the large number of thermal sensitive temperature control components and the required lines, they occupy a relatively large amount of internal space. This poses a significant challenge for small vacuum sealers with limited volume because the limited space needs to be utilized efficiently. Summary of the Utility Model

[0036] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0037] The thermal sensitive temperature control components of existing vacuum sealers require multiple connection lines, which increases the complexity of the internal structure. The complex thermal sensitive temperature control system increases the production cost. The numerous lines not only make assembly and maintenance difficult but also increase the probability of failures.

[0038] Moreover, due to the large number of thermal sensitive temperature control components and the lines they require, they occupy a relatively large amount of internal space. This poses a significant challenge for small vacuum sealers with limited volume, as the limited space needs to be utilized efficiently.

[0039] Refer to Figures 1-4 As shown, a vacuum sealer with a thermal sensitive temperature control component includes:

[0040] A main body 1, and a cover body 2 rotatably mounted on the main body 1;

[0041] A thermal sensitive temperature control component disposed inside the cover body 2, and a heat seal strip 31 disposed between the main body 1 and the cover body 2. The thermal sensitive temperature control component includes:

[0042] A heat conducting sheet 32 with one end abutted against the heat seal strip 31, and a temperature sensor 33 abutted against the other end of the heat conducting sheet 32;

[0043] An adjustment module 34 for regulating the temperature of the heat seal strip 31;

[0044] It also includes an IC board 35, which is electrically connected to the temperature sensor 33, the heat seal strip 31, and the adjustment module 34;

[0045] Through the cooperation of the heat conducting sheet 32 and the temperature sensor 33, the heating temperature of the heat seal strip 31 is monitored, and the temperature of the heat seal strip 31 is regulated through the cooperation of the IC board 35 and the adjustment module 34.

[0046] Place the item to be packaged into the vacuum bag, and then place the bag opening on the heat seal strip 31. Rotate and close the cover on the main body 1 so that it fits closely with the main body 1. At this time, the thermosensitive temperature control component inside the cover will start to work.

[0047] Start the vacuum sealer. The device will first extract the air inside the bag to form a vacuum environment. Next, the heat seal strip 31 heats up and starts to seal the bag opening.

[0048] During the heat sealing process, the heat conducting sheet 32 arranged inside the cover will transfer the temperature of the heat seal strip 31 to the temperature sensor 33. The temperature sensor 33 monitors the temperature of the heat seal strip 31 in real time and transmits the data to the IC board 35.

[0049] After receiving the temperature data transmitted by the temperature sensor 33, the IC board 35, through cooperation with the adjustment module 34, adjusts the temperature of the heat seal strip 31 in real time to ensure that the temperature of the heat seal strip 31 is maintained within the optimal range, thereby achieving an accurate heat sealing effect.

[0050] After the heat sealing is completed, the device automatically stops heating. At this time, the cover can be opened and the sealed vacuum bag can be taken out.

[0051] By integrating the temperature sensor 33, the adjustment module 34, and the IC board 35 inside the cover, the number of external wires to be connected is reduced, the complexity of the wiring and the occupation of the internal space are decreased. This makes the design more suitable for small vacuum sealers with limited volume. Integrating the temperature sensor 33 and the heat conducting sheet 32 directly inside the cover and making them work in cooperation with the heat seal strip 31 reduces the number of additional components and wiring requirements. This integrated design simplifies the structure of the device, improves the reliability and the convenience of maintenance.

[0052] The cooperation between the IC board 35 and the temperature sensor 33 enables the temperature of the heat seal strip 31 to be accurately controlled, avoiding problems such as poor sealing or bag damage caused by too high or too low temperature. This not only improves the sealing quality but also extends the service life of the device.

[0053] By integrating the key components inside the cover, the external connections and redundant components are reduced, making the structure of the device more compact and suitable for application scenarios with limited volume.

[0054] The integrated design not only improves the reliability of the equipment, but also makes the operation more convenient. The user only needs to close the cover to complete the vacuum pumping and heat sealing processes.

[0055] Through the precise cooperation of the IC board 35 and the adjustment module 34, the stability and consistency of the heat sealing temperature can be ensured under different environmental conditions, thus improving the quality of the seal.

[0056] The integrated design reduces the failure points of the equipment, makes maintenance more convenient, and simplifies the troubleshooting and repair processes.

[0057] The heat sealing strip 31 is embedded inside the cover, and the opening end of the vacuum bag is heat sealed through the heat sealing strip 31.

[0058] The heat conducting sheet 32 includes a positioning portion 321 penetrating through the IC board 35 and an abutting portion 322 abutting above the IC board 35. The heat conducting sheet 32 is fixed on the IC board 35 through the cooperation of the positioning portion 321 and the abutting portion 322. The end of the positioning portion 321 is connected to the temperature sensor 33.

[0059] Embedding the heat sealing strip 31 inside the cover can make the contact between the heat sealing strip 31 and the opening end of the vacuum bag closer and more uniform, thus ensuring that the bag mouth can be completely sealed during the vacuum pumping and heat sealing processes. It can also effectively utilize the space inside the cover, making the overall structure of the equipment more compact.

[0060] The embedding design ensures that the heat sealing strip 31 can uniformly heat the bag mouth, avoiding the problem of poor sealing caused by uneven heating.

[0061] Effectively utilize the space inside the cover, reduce the use of external components, improve the compactness and aesthetics of the equipment. Reduce heat loss, improve heat sealing efficiency, shorten the heat sealing time, and improve work efficiency.

[0062] The design of the heat conducting sheet 32 includes a positioning portion 321 penetrating through the IC board 35 and an abutting portion 322 abutting above the IC board 35, aiming to fix the heat conducting sheet 32 on the IC board 35 and ensure that the heat conducting sheet 32 can effectively transfer heat from the heat sealing strip 31 to the temperature sensor 33. Precise temperature monitoring and regulation can be achieved.

[0063] Through the cooperation of the positioning portion 321 and the abutting portion 322, the heat conducting sheet 32 can be stably installed on the IC board 35, ensuring the accuracy of its position and avoiding temperature sensing errors caused by loosening or displacement. The heat conducting sheet 32 can quickly and accurately transfer the temperature of the heat sealing strip 31 to the temperature sensor 33, ensuring the real-time and accuracy of temperature monitoring, and thus achieving precise temperature control.

[0064] The end of the positioning part 321 is connected to the temperature sensor 33. This fixing method ensures the close contact between the heat conducting sheet 32 and the temperature sensor 33, improving the reliability and sensitivity of temperature sensing. The close fit between the heat conducting sheet 32 and the IC board 35 helps reduce the interference of environmental factors on temperature sensing, enhancing the stability and accuracy of the system.

[0065] The heat conducting sheet 32 further includes a heat conducting part 323 abutting against the surface of the heat seal strip 31, and a guiding part 324 connecting the abutting part 322 and the heat conducting part 323. Heat is transferred through the heat conducting part 323, guiding part 324, abutting part 322, and positioning part 321. There is also a connecting part 325 between the guiding part 324 and the abutting part 322 below, and the guiding part 324 is extended through the connecting part 325 to increase heat attenuation.

[0066] Among them, by closely adhering to the surface of the heat seal strip 31, the heat conducting part 323 can efficiently absorb the temperature of the heat seal strip 31 to ensure the accuracy of temperature sensing. The guiding part 324 transfers the absorbed heat to the abutting part 322 and the positioning part 321, and then to the temperature sensor 33 to achieve real-time temperature monitoring.

[0067] The connecting part 325 extends the path of the guiding part 324, which helps increase the attenuation during the heat transfer process and prevent the temperature from being directly transferred to the temperature sensor 33 too high. This design can avoid errors caused by overheating of the temperature sensor 33 and improve the accuracy and stability of the temperature control system.

[0068] The designs of the guiding part 324, abutting part 322, and positioning part 321 enable heat to be transferred through a clear path. Such a design not only ensures the efficiency of heat transfer but also effectively controls the process of heat transfer.

[0069] The introduction of the connecting part 325 further optimizes the heat transfer process. By appropriately increasing heat attenuation, it ensures that the temperature signal received by the temperature sensor 33 is more stable and accurate.

[0070] Through the optimization of the heat transfer path and the heat attenuation design, component losses and failures caused by overheating are reduced, improving the stability and service life of the entire device. The heat attenuation design also improves the safety of the device, avoiding potential safety hazards caused by overheating, such as problems like overheating and damaging components.

[0071] It also includes a display board for displaying temperature, and the display board is electrically connected to the IC board 35. The heat conducting sheet 32 is made of a metal material. The heat conducting sheet 32 is made of aluminum material.

[0072] The secondary adjustment of the attenuated heat is carried out by the adjustment module 34, and the adjusted temperature is displayed through the display board. The specific operations of this process are as follows:

[0073] Assume that the temperature of the heat conduction part 323 of the heat conduction sheet 32 is 80 °C, and heat attenuation is carried out through the guiding part 324 and the connecting part 325 of the heat conduction sheet 32. For example, if the attenuation is 60%, then the temperature of the positioning part 321 in contact with the temperature sensor 33 is 32 °C.

[0074] The adjustment module 34 receives the temperature signal transmitted by the temperature sensor 33 and makes a secondary adjustment to the attenuated heat.

[0075] The adjustment module 34 precisely controls the heat to ensure that the temperature signal finally transmitted to the temperature sensor 33 is accurate.

[0076] The adjustment module 34 transmits the temperature data after the secondary adjustment to the display board.

[0077] The display board displays the temperature of the heat seal strip 31 and the adjusted temperature in real time, enabling the operator to intuitively understand the working state of the equipment.

[0078] The secondary heat adjustment mechanism can ensure that the temperature signal received by the temperature sensor 33 is more accurate, thereby achieving more precise temperature control. This precise control can further improve the heat seal effect and ensure the consistency of the quality of each seal.

[0079] The display board displays the temperature data in real time, and the operator can monitor the working state of the equipment at any time to ensure that the heat seal strip 31 works within the optimal temperature range. The real-time display function improves the operation convenience and safety of the equipment.

[0080] By adjusting the heat twice, the problem of temperature fluctuations caused by direct high-temperature transfer is avoided, and the stability and reliability of the system are improved. The adjustment module 34 can dynamically adjust the temperature according to the actual situation to ensure that the equipment can operate stably under different environmental conditions. The secondary heat adjustment reduces the potential damage to other components of the equipment caused by excessive temperature and extends the service life of the equipment. The real-time temperature display function enables the operator to discover and handle abnormal situations in a timely manner and prevent potential safety hazards.

[0081] Among them, the temperature sensor collects the temperature data of the positioning part of the heat conduction sheet in real time and transmits the data to the controller.

[0082] The controller compares the received temperature data with the preset temperature range. If the actual temperature deviates from the preset range, the controller will calculate the temperature value that needs to be adjusted.

[0083] The controller adjusts the power output of the heating module by adjusting the actuator, thereby adjusting the temperature of the heat seal strip.

[0084] The adjusted temperature change is collected again by the sensor and fed back to the controller to form a closed-loop control.

[0085] The heating module in the heat seal is the key part that provides the heat source, and its output power determines the temperature of the heat seal.

[0086] In addition, it also includes a heat insulation sheet 36. The heat insulation sheet 36 is embedded on the IC board 35 and is in contact with the heat conduction sheet 32. The purpose is to protect the IC board 35 from the heat transferred by the heat conduction sheet 32. The heat insulation sheet 36 is made of aerogel, and this material has excellent heat insulation performance. Aerogel is a lightweight and efficient heat insulation material with low thermal conductivity, which can effectively block the heat transfer and protect the IC board 35 from high-temperature damage.

[0087] The presence of the heat insulation sheet 36 effectively prevents the heat transferred by the heat conduction sheet 32 from directly acting on the IC board 35 and avoids the damage of the IC board 35 caused by high temperature. As a heat insulation material, aerogel has an extremely low thermal conductivity and can block the heat transfer to the greatest extent.

[0088] The heat conduction sheet 32 is in contact with the heat insulation sheet 36, which helps to evenly distribute the heat and reduce the thermal stress caused by local high temperature. This uniform heat distribution can reduce the stress generated by the temperature difference on the IC board 35 and lower the risk of structural damage.
