Description

Technical Field

[0001] The utility model belongs to the technical field of travel kettles, and specifically refers to a portable vacuum travel kettle. Background Art

[0002] For vacuum insulation, due to the reduction of gas pressure, the gas density will also decrease, the mean free path of gas molecules will increase, and the collision frequency and intensity between gas molecules and between gas molecules and the container wall will relatively weaken. In a vacuum, there is no medium to prevent the occurrence of convective heat transfer and contact heat transfer, so heat can be insulated. Vacuum insulation technology is widely used in the production of thermos cups to improve the heat preservation effect of thermos cups.

[0003] However, the existing portable vacuum travel kettles only have the function of heat preservation. When traveling in the wild in winter, after drinking the water in the thermos cup, it is impossible to obtain new hot water and gain heat. The lack of hot water for a long time will cause physical discomfort. Content of the Utility Model

When traveling in the wild in winter, after drinking the water in the thermos cup, it is impossible to obtain new hot water and gain heat. The lack of hot water for a long time will cause physical discomfort.

[0005] The technical solution adopted by the present utility model is as follows: A portable vacuum travel kettle provided by the present utility model includes a housing, a handle, a heating structure, and a heat preservation structure. The handle is arranged on the housing, the heating structure is arranged on the housing, the heat preservation structure is arranged on the housing. The heating structure includes an inner container, a vacuum chamber, a sealing seat, a battery, a control switch, a charging interface, and a heating copper ring. The inner container is arranged inside the housing and forms a sealed space with the housing. The vacuum chamber is arranged between the housing and the inner container. One end of the sealing seat is hermetically arranged on the inner container and the other end is hermetically arranged on the housing. The battery is fixedly arranged below the housing. The control switch penetrates through the housing and is electrically connected to the controller on the battery. The charging interface penetrates through the housing and is electrically connected to the controller on the battery. The heating copper ring penetrates through the heat preservation structure and is electrically connected to the controller on the battery.

[0006] Preferably, the heat preservation structure includes a heat preservation cover and a protective shell. The heat preservation cover is threadedly arranged outside the opening of the housing and the inner rubber plug is inserted into the inner container. The protective shell is threadedly arranged outside the housing and covers the heat preservation cover.

[0007] In order to better achieve the effect of vacuum sealing, the connection part of the heating copper ring to the power supply is sealed and connected by a sealing seat.

[0008] To achieve the purpose of heating faster, the battery is set as a charging power source and charged through a solar panel.

[0009] Furthermore, the inner liner is made of 304 stainless steel material.

[0010] The beneficial effects achieved by the present utility model with the above structure are as follows: A portable vacuum travel kettle proposed by this solution can add cold water into the inner liner and heat the cold water in the inner liner through a heating copper ring to obtain hot water.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, a portable vacuum travel kettle proposed by the present utility model includes a housing 1, a handle 2, a heating structure 3 and a heat preservation structure 4. The handle 2 is arranged on the housing 1, the heating structure 3 is arranged on the housing 1, and the heat preservation structure 4 is arranged on the housing 1. The heating structure 3 includes an inner container 5, a vacuum chamber 6, a sealing seat 7, a battery 8, a control switch 9, a charging interface 10 and a heating copper coil 11. The inner container 5 is arranged inside the housing 1 and forms a sealed space with the housing 1. The inner container 5 is made of 304 stainless steel material. The vacuum chamber 6 is arranged between the housing 1 and the inner container 5. One end of the sealing seat 7 is hermetically arranged on the inner container 5 and the other end is hermetically arranged on the housing 1. The battery 8 is fixedly arranged below the housing 1. The battery 8 is set as a charging power source and is charged by a solar panel. The control switch 9 penetrates through the housing 1 and is electrically connected to the controller on the battery 8. The charging interface 10 penetrates through the housing 1 and is electrically connected to the controller on the battery 8. The heating copper coil 11 penetrates through the heat preservation structure 4 and is electrically connected to the controller on the battery 8. The connection part of the heating copper coil 11 to the power supply is hermetically connected by the sealing seat 7.

[0019] As Figure 1 , Figure 2 and Figure 3 shown in the figure, the heat preservation structure 4 includes a heat preservation cover 12 and a protective shell 13. The heat preservation cover 12 is screwed on the outside of the opening of the housing 1 and the inner rubber plug is inserted into the inner container 5. The protective shell 13 is screwed on the outside of the housing 1 and covers the heat preservation cover 12.

[0020] During specific use, when the user uses this device, first put cold water into the inner container 5, then screw the heat preservation cover 12 onto the housing 1 to block the heating structure 3, and then screw the protective shell 13 onto the outside of the housing 1. Press the control switch 9 to connect the heating copper coil 11 and the battery 8 to the circuit. At this time, the heating copper coil 11 is energized to generate heat, thereby heating the water in the inner container 5. When it is heated to 60 degrees, the power is automatically cut off. Thus, the vacuum chamber 6 between the inner container 5 and the housing 1 reduces the heat molecule exchange and realizes the heat preservation effect, so that continuous hot water can be obtained in the wild. The above is the entire use process of the portable vacuum travel kettle.
