A mason jar sealing device comprises a mason jar main machine. The main machine includes a side wall and an isolation plate connected to the side wall, the isolation plate and a portion of the side wall disposed at a side of the isolation plate away from the mason jar body define a receiving cavity. A vacuum pump is arranged in the receiving cavity, another portion of the side wall is used to install the mason jar body. The mason jar body is arranged with a circular lid which is spaced apart from the isolation plate. When the mason jar body is installed to the side wall, the vacuum pump draws out air in the mason jar body to enable the circular lid to be attached to the mason jar body. The disclosure can seal the mason jar by the self-contained vacuum pump.
A food thermometer includes: a circuit board, a charging assembly, an energy storage element, an insulating member, a first metal housing, and a first temperature detection unit configured to detect a temperature of food. The circuit board is electrically connected to the charging assembly and the energy storage element; and the circuit board, the charging assembly and the energy storage element are disposed on one side of the insulating member. The first metal housing is electrically connected to the circuit board and is disposed on the other side of the insulating member. The first temperature detection unit is electrically connected to the circuit board to transmit a temperature signal to the circuit board, and the first metal housing is configured to transmit the temperature signal, as a wireless signal, to an external terminal.
A Mason jar sealing device includes: a mounting shell, a connection assembly, and an air pumping-inputting assembly. The mounting shell or the connection assembly defines an air inlet. An end of the connection assembly is connected to the mounting shell, and the other end of the connection assembly is connected to the Mason jar body. When in use, a sealing cavity is formed between the connection assembly and the Mason jar body, and the opening of the Mason jar body is located in the sealing cavity. The air pumping-inputting assembly is mounted on the mounting shell, the air pumping-inputting assembly is communicated with the air inlet and the sealing cavity, the air pumping-inputting assembly is configured to extract air out of the Mason jar body to enable the jar lid to seal to the Mason jar body.
B65D 81/20 - Containers, packaging elements, or packages, for contents presenting particular transport or storage problems, or adapted to be used for non-packaging purposes after removal of contents providing specific environment for contents, e.g. temperature above or below ambient under vacuum or superatmospheric pressure, or in a special atmosphere, e.g. of inert gas
B67B 3/24 - Special measures for applying and securing caps under vacuum
A mason jar sealing device comprises a mason jar main machine and a sealing converter; the mason jar main machine comprises an isolation plate and a first sleeve, an other side of the isolation plate is arranged with a receiving cavity, and a vacuum pump is arranged in the receiving cavity, the first sleeve is used to install the first mason jar body; both ends of the seal converter are respectively arranged with a connecting part detachably connected with the first and second sleeve, and a circle lid is arranged in the second sleeve; when the mason jar body extends into the sleeve, the vacuum pump draws out the air in the mason jar body and the sleeve to seal the mason jar body and the circular lid. The disclosure can seal the mason jar by the self-contained vacuum pump, and seal the mason jars of different diameters.
