The utility model discloses a constant temperature heat preservation container, which comprises a cavity structure which is composed of a heat preservation shell 1 and a liner wall 3 which are sleeved together and has an upward opening, a container cover 13 is arranged above the heat preservation shell 1 and the liner wall 3, the space between the heat preservation shell 1 and the liner wall 3 is divided into a vacuum chamber 2 and an air chamber 4, the wall of the heat preservation shell 1 corresponding to the air chamber 4 is provided with an air hole 5, the air chamber 4 is provided with an opening and closing structure of the air hole 5, the opening and closing structure comprises a bimetallic strip structure and a sealing pad 9 which are connected with the air chamber 4 or the liner wall 3, the bimetallic strip structure is respectively an inner metal strip 81 close to the liner wall 3 and an outer metal strip 80 far away from the liner wall, the free ends of the bimetallic strips are connected with the sealing pad 9 together, the bimetallic strips extend out from one end of the air chamber 4 close to the liner wall to the direction of the heat preservation shell, the thermal expansion coefficient of the outer metal sheet 80 is greater than that of the inner metal sheet 81, the sealing gasket 9 is aligned with the air hole 5, and the air hole 5 is opened and closed through expansion or contraction of the bimetallic strip.
Preferably, the opening and closing structures are more than two groups and are uniformly distributed at the same height of the air chamber 4 around the wall surface 3 of the inner container, and all the opening and closing structures at the same height form an opening and closing structure unit layer.
Preferably, the opening and closing structure unit layers are more than two layers and distributed at different heights around the wall surface 3 of the inner container.
In order to arrange more than two opening and closing structure unit layers conveniently, the space between the heat-insulating shell 1 and the wall surface 3 of the inner container is divided into an upper part, a middle part and a lower part, the upper part and the lower part are air chambers 4, one opening and closing structure unit layer is arranged in each air chamber, and the middle part is a vacuum chamber 2.
Further, as shown in fig. 1, vacuum chambers 2 are further provided above and below the upper and lower air chambers, so that the outer air chamber of the whole inner container wall is divided into five parts, which are, from top to bottom, a vacuum chamber, an air chamber and a vacuum chamber.
The bimetallic strip structure is connected with the wall surface 3 of the liner through a movable seat 7 and a fixed seat 6, the fixed seat 6 is fixedly sleeved outside the wall surface of the liner and has a certain width in the radial direction, the movable seat horizontally slides on the fixed seat 6 through a sliding groove structure, and one end of the bimetallic strip is connected with the fixed seat; the middle of the movable seat 7 is provided with a rotating shaft 10, the outer end of the movable seat is provided with an adjusting rod 12 connected with the rotating shaft 10, the adjusting rod 12 penetrates through the outer portion of the heat preservation shell 1, the adjusting rod 12 is sleeved with an adjusting valve 11, and the adjusting rod 12 is pushed and pulled through the adjusting valve 11 so as to adjust the position of the rotating shaft 10 in the sliding groove.
The utility model discloses a theory of operation:
when hot water is filled in the container, the container cover 13 is tightly screwed, and the heat of the liquid in the container is mainly transferred to the inner container wall surface 3 in a heat conduction mode.
Bimetallic strip stretches out from the one end that air chamber 4 is close to the inner bag wall to the direction of lagging casing and forms the bent arm structure, when the temperature is higher than the temperature of settlement, bimetallic strip 8 is heated the expansion and is crooked, because bimetallic strip 8 thermal expansion coefficient is different, outer sheetmetal 80 expansion coefficient is greater than the expansion coefficient of interior sheetmetal 81, then the crooked range of outer sheetmetal 80 is bigger, drive interior sheetmetal and sealed pad 9 syntropy and remove to the direction of inner bag wall 3, gas pocket 5 is opened, outside air current and 4 interior air intercommunications of air chamber, can with the contact heat transfer of inner bag wall 3, the temperature reduction with higher speed, hot-water heat passes through inner bag wall 3 at this moment and mainly transmits outside air with heat-conducting mode, realize temperature rapid cooling.
When the temperature is gradually reduced to the set temperature, the bimetallic strip 8 is restored and deformed to gradually restore the original position, when the temperature is reduced to the set temperature range, the air hole 5 is blocked by the sealing gasket 9, the external air flow is isolated from the wall surface 3 of the liner, and the heat of the hot water is hardly transferred to the outside, so that the function of keeping the temperature of the container at the set temperature is achieved. The vacuum chamber 2 is used for reducing the heat transfer of the inner container wall surface 3 through the air between the inner container and the shell as much as possible and enhancing the heat preservation effect.
When the constant temperature value needs to be increased, the adjusting valve 11 rotates the movable seat 7 to enable the sealing gasket 9 to be far away from the inner container, and the adjusting rod 12 and the adjusting valve 11 can adopt simple screw and nut structures, so that the sealing gasket 9 seals the air hole 5 in advance in the process that the bimetallic strip 8 is restored by the reduction of the temperature of the liquid; when the constant temperature value needs to be reduced, the adjusting valve 11 rotates the movable seat 7 to enable the sealing gasket 9 to be close to the inner container, so that the sealing gasket 9 delays to seal the air hole 5 in the process that the bimetallic strip 8 is restored due to the reduction of the temperature of the liquid, and the adjustment of the constant temperature value is further realized.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
