As shown in fig. 1 to 4, an embodiment of the present application provides a heat preservation bowl, which includes a casing 1 and an inner container 2, wherein the inner container 2 is sleeved in the casing 1, and an interlayer 3 is formed between the inner container 2 and the casing 1. The shell 1 is connected with a sealing plug 4, the shell 1 is provided with a pressure relief hole 11, and the sealing plug 4 can block the pressure relief hole 11 when the air pressure in the interlayer 3 is balanced with the external air pressure; the sealing plug 4 is also capable of opening the pressure relief hole 11 when the air pressure in the interlayer 3 is lower than the external air pressure.

In the heat preservation bowl that this application embodiment provided, inner bag 2 can be stainless steel material to make inner bag 2 have the heat conductivility of preferred. The shell 1 can be made of plastic materials, so that the shell 1 is not easy to conduct heat, and the purpose of heat preservation of the inner container 2 is achieved.

The heat preservation bowl that this application embodiment provided, when needs heat/keep warm to inner bag 2, can pour into hot water into to the intermediate layer 3 between shell 1 and the inner bag 2 to the food heating in the inner bag 2. When the inner container 2 and the outer shell 1 need to be detached along with the cooling of the hot water to respectively clean the inner container and the outer shell, at the moment, because the air pressure in the interlayer 3 is lower than the external air pressure, the sealing plug 4 can be pushed away from the pressure relief hole 11 under the action of the air pressure difference to open the pressure relief hole 11, so that the external air is communicated with the air in the interlayer 3. After the air pressure reaches balance, the inner container 2 can be easily taken down due to the fact that negative pressure does not exist in the interlayer 3, and cleaning is facilitated.

In addition, the sealing plug 4 and the cooperation of pressure release hole 11 can not need manual plug sealing plug 4 just can realize the intercommunication of air in the intermediate layer 3 with outside, has more made things convenient for the user to wash the heat preservation bowl.

In a specific embodiment, the sealing plug 4 comprises a sealing skirt 41, the sealing skirt 41 being capable of sealing against the inside of the casing 1 when the air pressure inside the interlayer 3 is greater than the external air pressure; the sealing skirt 41 is also capable of opening the pressure relief hole 11 when the air pressure in the sandwich 3 is lower than the external air pressure.

When food needs to be heated/insulated, hot water is injected into the shell 1, the inner container 2 is placed on the shell 1, the hot water is stored in the interlayer 3, the inner container 2 and the shell 1 are sealed, the air pressure in the interlayer 3 is larger than the external air pressure, and the sealing skirt edge 41 is pressed on the inner side of the shell 1, so that the sealing skirt edge 41 can well seal the pressure relief hole 11.

Further, the sealing plug 4 comprises a sealing post 42, and the housing 1 is provided with a fixing hole 12. The sealing post 42 cooperates with the fixing hole 12 to connect the sealing plug 4 to the housing 1.

Through setting up sealing post 42 and the cooperation of fixed orifices 12, connect sealing plug 4 on shell 1, when needing to dismantle the washing to inner bag 2, can need not to take off sealing plug 4 from shell 1. When it is desired to clean the sealing plug 4, the sealing post 42 can be removed from the mounting hole 12 and the sealing plug 4 can be cleaned after the sealing plug 4 is removed from the housing 1. The sealing column 42 is simple in structure matched with the fixing hole 12 and reliable in connection.

Furthermore, the sealing post 42 is provided with a limiting protrusion 421, and the limiting protrusion 421 is clamped and fixed with the fixing hole 12. The connection reliability of the sealing plug 4 and the shell 1 is further improved by the clamping fit of the limiting protrusion 421 and the fixing hole 12, and the sealing plug 4 is prevented from falling off due to overlarge air pressure difference.

In a specific embodiment, the heat preservation bowl further comprises a handle 5 which is sleeved on the outer side of the shell 1 and abuts against and presses the inner container 2.

When food needs to be heated/insulated, hot water is injected into the shell 1, then the liner 2 is placed on the shell 1, the hot water is stored in the interlayer 3, the handle 5 is sleeved on the shell 1 and abuts against and compresses the liner 2, and therefore the liner 2 is fixed. In particular, the handle 5 may be detachably connected to the housing 1, for example, a threaded connection, a snap connection, or the like may be provided. The handle 5 can also cover the pressure relief hole 11, so that the heat in the interlayer 3 is reduced to be dissipated. Due to the sealing effect of the handle 5, the air pressure in the interlayer 3 can be kept larger than the external air pressure, the sealing plug 4 can stably plug the pressure relief hole 11, and the heat preservation effect is improved. Moreover, the handle 5 covers the position of the pressure relief hole 11, and scalding caused by misoperation can be prevented.

Further, the housing 1 is provided with a limit step 13 to limit the handle 5.

In a specific embodiment, the sealing plug 4 further comprises a body portion 43, the body portion 43 blocks the fixing hole 12, the sealing post 42 is connected to the body portion 43, and the sealing skirt 41 is connected to the body portion 43 along the circumferential direction of the body portion 43.

This body part 43 can block the fixed hole 12, when food needs to be heated, the sealing performance in the interlayer 3 is ensured, on one hand, heat loss is avoided, on the other hand, pressure relief can be prevented, and the sealing skirt 41 of the sealing plug 4 blocks the pressure relief hole 11.

In a specific embodiment, the housing 1 is provided with a recessed surface 14 recessed from the outside to the inside, and the fixing hole 12 is opened on the recessed surface 14.

The fixing hole 12 is formed in the recessed surface 14, so that the fixing hole 12 can be spaced apart from the handle 5, and the sealing post 42 can be inserted through the fixing hole 12 without interfering with the handle 5 and affecting the assembly.

Further, referring to fig. 4, after the inner container 2 is placed on the outer container 1, a gap still remains between the outer container 1 and the inner container 2, so that a sealing ring 7 may be disposed between the inner container 2 and the outer container 1 to seal the interlayer 3 at the upper opening of the outer container 1. The handle 5 is sleeved on the shell 1, and the end part of the handle 5 can abut against and press the outer side of the inner container 2, so that the inner container 2 is fixed.

In a specific embodiment, as shown in fig. 1, the heat preservation bowl further includes an upper cover 6 fastened to the inner container 2, and the upper cover 6 is provided with an exhaust valve 61. After the food in the heat preservation bowl is heated, the exhaust valve 61 can be opened, the air pressure in the inner container 2 of the heat preservation bowl is released firstly, and then the upper cover 6 is opened, so that the risk of scalding caused by directly opening the upper cover 6 is avoided.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
