Description

a heating vessel

Technical field:

The invention relates to a portable heating container, in particular to a container that can be self-heated or heated with solid alcohol.

Background technique:

There are many forms of self-heating container solutions. According to its basic working principle, it is basically divided into three categories. The most common one is that two substances capable of exothermic reaction (usually water and quicklime) are separately placed at the bottom of the tank with a diaphragm, and the diaphragm is broken when needed. , to make it mix and generate an exothermic reaction for heating; the second is to directly use an open flame to heat at the bottom of the tank.

However, the disadvantage of the first solution is that it is easy to misuse, cause the two substances to be accidentally mixed for heating or easily cause the reaction substance to fail, and generally can only be used once, and when the reaction substance mixes and produces an exothermic reaction, it can cause danger. The pressure of the accumulated steam. For example, CN2734667Y discloses a kind of canned food with heating device, and it is only one example of adopting this type of heating method. The second kind of scheme has the defect that self-heating cannot be carried out. For example, CN201362446Y discloses a kind of canned hot pot, and CN101342972A discloses a cooking bowl with its own heating device.

Invention content:

In view of the above disadvantages, the present invention has been made. The object of the present invention is to provide a portable heating container aimed at the deficiencies of the prior art, which can be self-heated, is not prone to misoperation, is not easy to cause the reaction substance to fail, also increases the heating area, and avoids the The steam generated by the reaction creates excessive pressure, and solid alcohol can also be used for heating.

In order to achieve the above object, the present invention is achieved through the following technical solutions: the container of the present invention includes a first cavity and a second cavity, the first cavity is used to hold the contents of the container, and the second cavity is used to hold Put the heating body, a base is used to close the second cavity, a container cover is used to close the first cavity, the first cavity is made of heat-conducting material, and its peripheral wall has a spiral groove, the first cavity The inner wall of the second cavity is coated with a flame-retardant and heat-insulating layer, the outer wall of the second cavity is provided with a handle, the base is sealed and engaged on the lower end of the second cavity and recessed upward, and the inner wall of the second cavity There are upper and lower layers of protrusions protruding radially inward. The upper layer of protrusions is used to assist the first cavity. A pointed screw that can be rotated by a nut located in the center of the base is also provided in the base. A small hole is arranged on the upper part of the second cavity, and the small hole is closed by a one-way closure before heating, and the one-way closure is opened when the pressure in the second cavity reaches 12 kPa after heating.

The heating body is water contained in a water bag and quicklime.

The lower protrusion is used to support the water bag, and the water bag will be punctured when the pointed screw rotates.

A gasket for sealing is provided between the base and the lower end of the second cavity.

Beneficial effects of the present invention: self-heating is possible, misoperation is not easy to occur, and the reaction substance is not easy to fail, and the heating area is increased, and excessive pressure of steam caused by the reaction is avoided. Solid alcohol can also be used for heating after self-heating.

Detailed ways:

Accompanying drawing 1 is the schematic structural view of the container of the present invention, including a first cavity 1 and a second cavity 2, the first cavity is used to hold the contents of the container, and the second cavity is used to hold a heating body. The base 3 is used to close the second cavity 2, and the container cover 4 is used to close the first cavity. The first cavity is made of heat-conducting material, and has a helical groove on its peripheral wall, and the groove increases the contact area of the first cavity, so that heat is received more rapidly and the heat exchange speed is accelerated. The inner wall of the second cavity is coated with a flame-retardant and heat-insulating layer to prevent heat loss through the wall of the second cavity. In addition, a handle 5 is also provided on the outer wall of the second cavity, so that the user can hold it more easily. The base 3 is threaded on the lower end of the second cavity and is recessed upwards. Because the base is recessed upwards, the nut is positioned higher than the lower end of the second cavity and hidden therein, so it is not easy to be accidentally rotated when not in use.

More preferably, a cover can be installed under the base to protect it, or a limiting element that can be removed during use can be installed between the nut and the base to prevent the nut from moving upward.

A pointed screw 9 that can be rotated by a nut 8 located at the center of the base is also provided in the base, and a small hole 10 is provided on the upper part of the second cavity, and the small hole is closed by a one-way closure 11 before heating. Closed, when the pressure in the second cavity reaches 12 kPa by heating, the one-way closure is opened so that the excessive pressure is released.

As shown in Figures 1 and 2, the inner wall of the second cavity is provided with upper and lower layers of protrusions 6 and 7 protruding radially inward, and the upper layer of protrusions 6 is used for auxiliary support of the first cavity. The lower protrusions are used to support the water bag, and the protrusions can be evenly distributed on the inner wall of the second cavity along the circumference.

The heat conducting material may be metal materials such as aluminum and stainless steel.

When performing self-heating, first open the container cover 4, then turn the nut 8, so that the pointed screw 9 turns upwards, pierces the water bag 12, makes the water flow down, mixes with the quicklime in the base, and releases heat reaction. When the released heat makes the pressure in the second cavity reach 12 kPa, the one-way closure 11 that seals the small hole 10 on the upper part of the second cavity is opened outwards to release the pressure until the heating is completed.

When used next time, the base can be unscrewed and solid alcohol or other fuels can be put in, and the one-way closure can be kept open for heating.

The above are only preferred embodiments of the invention, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the invention patent application are included in the invention patent application scope.
