[0001] The utility model relates to the technical field of liquid heating, in particular to a split-type portable induction heating thermos cup. Background Art

[0002] Portable heating cups are popular in the market due to their advantages of being easy to carry, heating and heat preservation. Existing portable heating cups generally include a cup body and a heating component, wherein the bottom of the cup body is open, and the heating component is fixedly connected to the bottom of the cup body. The heating component generally uses a PTC or other resistive heating component, but the above structure has at least the following disadvantages:

DETAILED DESCRIPTION

[0031] In order to make the present invention more clear, a split portable induction heating thermos cup of the present invention is further described below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0032] like Figures 1 to 4As shown, a split portable inductive heating thermos cup includes a cup body 100 and a base 200, and the cup body 100 and the base 200 are connected in a detachable manner by a screw-on structure. The cup body 100 has a container 110 that can hold liquid, and the container 110 is a cylindrical container with an upper opening, and a cup cover 103 can be sealed and connected at the opening. An inductive heating element 120 containing an iron-based material is provided at the bottom of the container 110. The inductive heating element 120 can be directly attached and connected to the bottom of the cup body 100 in a physical manner, or can be directly connected to the bottom of the container 110 as a substrate to form an integral connection. For example, the container 110 itself is made of food-grade stainless steel, and the inductive heating element 120 uses the bottom wall of the container 110 as a stainless steel substrate 121, and a food-grade titanium-containing metal coating 122 is provided on the inner wall (inner side of the container) of the stainless steel substrate 121. In this way, the inductive heating element 120 is in direct contact with the liquid inside the container 110 to improve the heat exchange efficiency and reduce heat loss. A temperature probe 101 for sensing the liquid temperature is also provided at the bottom of the container 110, and is electrically connected to the upper coupler 102 at the bottom of the cup body 100. The temperature probe 101 is preferably a non-contact infrared temperature probe, and the temperature compensation setting in the program can also meet the requirement of accurate temperature measurement of the water temperature of the thermos cup. Of course, the temperature probe 101 can also be an NTC probe directly in contact with the container 110.

[0033] The base 200 is provided with an induction coil 201, a control module 300 and a power module 400. The upper side of the base 200 is provided with a lower coupler 202 which can be electrically connected to the upper coupler 102. The induction coil 201, the power module 400 and the lower coupler 202 are electrically connected to the control module 300 respectively. The induction coil 201 is in the form of a sheet as a whole, and is formed by spirally winding a copper wire with an insulating layer to minimize the height of the device as much as possible. Its shape is adapted to the shape of the bottom of the container 110. In this embodiment, both are circular. The control module 300 selects the set heating temperature and the whole machine switch through the control panel. When the cup body 100 is connected to the base 200, the induction heating element 120 is located directly above the induction coil 201, and the distance between the two is between 0-10mm to reduce the attenuation loss of the electromagnetic energy. At the same time, this distance range makes the overall height of the device more suitable and also better in portability.

[0034] like Figure 5The screw-on structure is a screw groove 501 and a screw-on head 502 respectively arranged on the cup body 100 and the base 200. Specifically, a circular mounting groove 140 is provided at the bottom of the cup body 100, and a mounting boss 210 is provided on the upper part of the base 200, which is clearance-matched with the mounting groove 140. The outer contour of the mounting boss 210 is adapted to the notch shape of the mounting groove 140. The screw groove 501 is located on the inner wall of the mounting groove 140, and the screw groove 501 has a spiral diameter structure, and its lower end is open for the insertion of the screw-on head 502; the screw-on head 502 is located on the outer peripheral side of the mounting boss 210, and the screw-on head 502 is inserted into the screw groove 501. When the two rotate relative to each other, the connection and disassembly of the cup body 100 and the base 200 can be realized. It should be emphasized that the contour shapes of the screw groove 501 and the screw-on head 502 are adapted, the clearance between the two is moderate, and the sliding smoothness is good. Considering that the cup body 100 and the base 200 have relative movement when connected and disassembled, the upper and lower couplers are 2-pin magnetic connectors, which can be stably connected in the relative movement structure to maintain the stability of the electrical signal connection.

[0035] Recombination Figure 1 , Figure 2 As shown, the cup body 100 further includes a metal shell 130, the container 110 is located inside the metal shell 130, and the side of the container 110 forms a vacuum isolation with the metal shell 130, and the temperature conduction is reduced by the vacuum to improve the heat preservation and heat insulation effect of the cup body 100. Of course, without considering the physical heat preservation performance, the cup body 100 can also have some other shell structures, such as silicone, plastic and other shell forms, and the control module 300 of the device controls the operation of the induction coil 201 to maintain the temperature within a certain range.

[0036] Since this device uses electromagnetic induction to generate eddy current heating to achieve liquid heating, in order to reduce electromagnetic interference with the normal use and operation of electrical components, combined with Figure 1 As shown, an electromagnetic shielding body 203 is provided in the base 200, the control module 300 and the power module 400 are both located at the lower side of the electromagnetic shielding body 203 and in the lower shell 204 of the base 200, and accordingly, the induction coil 201 is located at the upper side of the electromagnetic shielding body 203 to ensure that the electromagnetic effect generated upward by the induction coil 201 is not shielded, and the electromagnetic shielding body 203 also serves as a supporting structure for the induction coil 201. Here, the electromagnetic shielding body 203 is a conventional structure of an induction cooker in a small household appliance and is not described in detail.

[0037] Taking into account the portability and multi-scenario application requirements of the device, the power module 400 is a 220V plug-in power module or an adapter plug-in power module, which has an exposed socket and can be used as a heating container in a place with a fixed power supply. In addition, the power module 400 can also preferably adopt a rechargeable battery module, which includes a rechargeable battery 401, and the rechargeable battery 401 is located in the lower shell 204 in the base 200, and is fixedly connected by gluing, clamping, etc. In this way, the device can be used when going out, and is powered by a rechargeable battery, which solves the problem of power supply mobility and is more convenient to use. More importantly, the device is a detachable structure, which is more conducive to storage and carrying.

[0038] Before the device is working, the cup body 100 needs to be installed on the base 200 to ensure electrical conduction between the two. Then operate the control panel to control the heating water temperature, and the control module 300 controls the induction coil 201 to work. Under the action of magnetic induction, the induction heating element 120 is heated and heats the liquid in the container 110. When the liquid temperature reaches the set temperature, the control module 300 receives the signal of the temperature probe 101, and controls the induction heating element 120 to stop working after judging through its internal program; when the water temperature drops below the set temperature, the control module 300 controls the induction coil 201 to work again, repeats the above steps, and maintains the water temperature within a certain range to achieve the heating and heat preservation functions. Of course, according to the specific program setting of the device, the above working process is only an illustrative description. The specific operation is not limited.

[0039] The above embodiments of the utility model are merely examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the utility model still belong to the protection scope of the utility model.
