[0002] A household vacuum heat sealer is a small household kitchen appliance. The seal on the upper cover and the seal on the base are arranged correspondingly. The vacuum packaging bag to be heat-sealed is placed between the upper cover seal and the base seal, and then the upper cover and the base are clamped, and the air in the vacuum packaging bag is extracted through the built-in small vacuum pump and the exhaust groove. In actual use, after the vacuuming is completed, the bag opening of the vacuum packaging bag is hot-melted and solidified through the heat sealing component installed on the front side of the base seal to form a sealing strip that seals the bag opening, so that the items in the packaging bag can be stored, especially the food can be vacuum-preserved and stored.

[0003] In actual use, in order to successfully complete the vacuuming of the vacuum packaging bag, the base seal needs to be provided with an exhaust groove. Once the food in the vacuum packaging bag overflows, the exhaust groove will be contaminated.

[0004] At present, the household vacuum heat sealing machines on the market set the vacuum pump, heat sealing components and the exhaust trough together, and the vacuum pump and the heat sealing components need to be powered on to work. This makes it difficult to completely disassemble and clean the exhaust trough, which easily causes dirt accumulation. In serious cases, it will affect the performance and life of the household vacuum heat sealing machine.

[0005] Moreover, if the vacuum tank is cleaned directly, it is easy to cause a short circuit in the circuit, or water ingress may damage the electrical connection, shortening the life of the product and easily causing a leakage hazard. Utility Model Content

[0058] Optionally, a locking member 132 is further provided on the connecting shaft 133 , and the locking member 132 is used to further stabilize the connection and prevent the lower shell 12 from making unnecessary movements.

[0059] In one embodiment, the locking member 132 is a spring, and the spring is sleeved on the connecting shaft 133 .

[0060] Optionally, a locking mechanism is further provided on the connecting member 131. When the connecting member 131 is connected to the base 2, the locking mechanism can be used to lock the connecting member 131 so that the connecting member 131 will not be accidentally separated from the base 2, and the connection is very reliable.

[0061] Specifically, after installing components such as the circuit board 14, the first seal 15, the vacuum pump 18, the air pipe 17 and the heat sealing assembly 19 on the lower shell 12, the connecting shaft 133 is then installed into the corresponding mounting hole on the lower shell 12, and then the locking piece 132 is sleeved on the connecting shaft 133. At this time, the locking piece 132 will be squeezed to generate elastic force, and the connecting shaft 133 cannot move left and right, so that the entire connecting mechanism 13 cannot move left and right. When disassembling the connecting mechanism 13, you only need to remove the locking piece 132 from the connecting shaft 133, and then take the connecting shaft 133 out of the mounting hole of the lower shell 12.

At this time, the upper cover 1 and the base 2 can only rotate relative to each other, and no other movement will occur.

[0069] When the base 2 needs to be disassembled and cleaned, the connecting member 131 only needs to be rotated in the opposite direction until the locking mechanism leaves the connecting groove 21, and the connecting member 131 can be disconnected from the connecting groove 21, so that the base 2 can be taken out for disassembly and cleaning.

[0070] Optionally, the connection mechanism 13 is further connected to a sealing block 134 for maintaining the sealing performance of the inner space of the upper cover 1 .

[0071] Optionally, in order to facilitate the use of the utility model anytime and anywhere, a battery is further provided in the upper cover 1 to supply power to the circuit board 14 .

[0081] Optionally, the sealing strip 24 is made of rubber.

[0082] Specifically, when vacuum heat sealing operation is required, first click the corresponding switch button on the control panel 16 to power on the circuit board 14, and then place the vacuum packaging bag to be vacuum heat sealed on the second sealing member 23, manually or by clicking the corresponding button on the control panel 16, so that the first sealing member 15 is rotated in the direction close to the second sealing member 23 until the first sealing member 15 moves to the heat sealing position, the lock 110 is engaged with the lock groove, and the upper cover 1 and the base 2 are fastened. At this time, the first sealing member 15 and the second sealing member 23 are squeezed while clamping the vacuum packaging bag to form a sealed cavity, and then the vacuum pump 18 evacuates the vacuum packaging bag through the air pipe 17. After the evacuation is completed, the heat sealing component 19 is instructed to vacuum heat seal the vacuum packaging bag. After the preset vacuum heat sealing time, the operation can be completed, which is very simple and efficient.

[0083] Furthermore, since no parts requiring electricity are arranged on the base 2, the base 2 does not need to be connected to a power source. Therefore, the base 2 and the upper cover 1 are detachably connected without affecting the vacuum heat sealing performance.

[0084] At the same time, with such an arrangement, the entire base 2 can be disassembled and cleaned with water or detergent. When the air extraction groove 25 is dirty and needs to be disassembled and cleaned, the base 2 can be directly disassembled and then thoroughly disassembled and cleaned with a detergent, and there will be no situation where dirt accumulates in the air extraction groove 25.

[0085] Optionally, since the base 2 and the upper cover 1 of the utility model are detachably connected, the base 2 and the upper cover 1 can be repaired and replaced separately, further reducing the cost of repair.

[0086] Furthermore, the upper cover 1 and the base 2 can be used in combination with other components that can be used in combination, thereby further improving the flexibility and practicality of the utility model.

[0087] Furthermore, a TYPE-C charging port can be added to the upper cover 1. When there is no external power supply, it can be powered by a spare rechargeable battery, making the usage scenario more flexible.

[0088] The utility model has the characteristics of stable structure, small size, convenient disassembly and cleaning, flexible use and high practicality.
