Description

Heat-insulating container

Technical Field

The utility model belongs to the technical field of heat preservation container, a heat preservation container is related to.

Background

The heat-insulating container is a water-holding container made of ceramic or stainless steel and vacuum layer, and its top portion is equipped with cover, and is tightly sealed, and the vacuum heat-insulating layer can make the liquid of water, etc. placed in the interior delay heat-radiation so as to attain the goal of heat-insulating. The heat preservation container is developed from a vacuum flask, the heat preservation principle is the same as that of the vacuum flask, and people only make the vacuum flask into a cup conveniently. There are three ways thermal power can be transmitted: radiation, convection, and transfer. The silver cup liner in the heat preservation container can reflect the radiation of hot water, and the vacuum of the cup liner and the cup body can block the heat transfer. The improvement of the heat preservation effect of the existing heat preservation container is always a main technical problem in the field, the breakthrough opening is always searched in the field of heat preservation materials, the heat preservation material with outstanding effect is provided, and when the material is applied to the heat preservation container to keep the overall conformity of the heat preservation container, a series of technical problems that the color and luster of the existing heat preservation container are not beautiful enough, the sealing effect is not good, tea leaves are easily left on a cup body, a base is easily broken and the like are also needed to be overcome. The problem to be solved is that the problem to be solved is not easy to be solved at present.

SUMMERY OF THE UTILITY MODEL

Not enough to current technique, the utility model provides a heat preservation container. The technical problem to be solved is how to improve the knock resistance of the bottom of the heat-preservation container and improve the safety.

In order to realize the purpose, the utility model adopts the technical scheme that:

the utility model provides a heat preservation container, includes the upper cover, inner bag and shell, the shell has the inner chamber, be equipped with the opening on the shell up end, opening threaded connection has the upper cover, the inner chamber just with inner chamber wall fixed connection including the inner bag sets up, the shell lower extreme is sealed and has linked firmly the heelpiece, be equipped with logical groove on the upper cover up end, it runs through upper cover and shell inner chamber intercommunication to lead to the groove, it is provided with discharge valve to lead to the inslot, still have the flange on the upper cover outer peripheral face, the annular has on the flange, be equipped with the handle that matches with the ring groove shape in the annular, still be equipped with the mounting hole on the annular, the handle passes through spring locating pin and mounting hole fixed connection, and the handle can be followed spring locating pin circumference and rotated, be equipped.

The lower end of the shell is sealed and fixedly connected with a bottom pad, the bottom pad plays a role in protecting the bottom surface of the shell, the bottom surface of the shell can be effectively protected from collision, and the wear resistance is improved. The upper end surface of the upper cover is provided with a through groove which penetrates through the upper cover to be communicated with the inner cavity of the shell, and an exhaust valve is arranged in the through groove. The through groove and the exhaust valve are arranged to play the following roles: when the heat preservation container is used, people usually make tea or carry hot water, and for any reason, the heat preservation container is always filled with the hot water, the hot water can form hot air, the heat preservation container is a closed space, and when people open the cup cover, water drops can splash. The temperature of the water drops is very high, the water drops can cause serious scald when being sputtered to the skin of people and can scald water bubbles, and the safety performance is not good. The through groove and the exhaust valve on the heat preservation container can exhaust high-temperature and high-pressure gas in the liner, so that the air pressure in the heat preservation container is kept equal to other outside air. The water drops that can not produce when we open the upper cover splashes for this heat preservation container security performance obtains great promotion.

The flange is provided with a ring groove, a lifting handle matched with the ring groove in shape is arranged in the ring groove, the ring groove is further provided with a mounting hole, the lifting handle is fixedly connected with the mounting hole through a spring positioning pin, and the lifting handle can rotate along the circumferential direction of the spring positioning pin. The design of handle makes us have had one more way of holding and pinching when carrying the insulated container at ordinary times, prevents that we from holding hard. The outer peripheral surface of the shell is provided with the sunken part, and the shell is smooth due to the fact that the heat preservation container is generally cylindrical, and the shell can easily slide out of a palm when being held and pinched, so that the shell is broken. The design of the concave part greatly increases the friction force between the shell of the heat preservation container and the palm of the user, and prevents the shell from falling out. The arrangement greatly improves the knock resistance and safety of the heat-insulating container.

In the above thermal insulation container, the lower end of the flange of the upper cover is provided with a threaded connection part, a sealing washer is sleeved on the outer peripheral surface of the threaded connection part, and the threaded connection part is in threaded connection with the upper end of the shell.

The sealing performance between the upper cover and the shell is greatly improved due to the arrangement of the sealing washer.

In the above thermal insulation container, a diversion trench is further arranged on the upper end surface of the upper cover.

The effect of guiding gutter groove is that the vapor in the inner bag discharges through logical inslot, meets that external temperature is lower and can condense into the drop of water and attach to near the outer notch of logical groove. The guide groove is used for enabling the condensed water drops to flow out along the guide groove.

In the above thermal insulation container, the exhaust valve is made of a silica gel material, and the bottom pad is made of a silica gel material.

The bottom pad is made of silica gel materials, so that the safety of the heat-insulating container is greatly improved, and the silica gel has good shock resistance. When the heat preservation container is placed on a table at ordinary times, the silica gel bottom pad can play a role in damping and preventing noise.

In the above thermal insulation container, the outer shell is made of stainless steel, the inner container is made of stainless steel, and the handle is made of stainless steel.

(claim of the specification)

The utility model has the advantages that: the design of depressed part makes heat preservation container shell and our palm frictional force greatly increased, sets up like this and has promoted heat preservation container's resistant nature and security of knocking over greatly. The bottom pad is made of silica gel materials, so that the safety of the heat-insulating container is greatly improved, and the silica gel has good shock resistance. When the heat preservation container is placed on a table at ordinary times, the silica gel bottom pad can play a role in damping and preventing noise.
