DETAILED DESCRIPTION

[0030] To make the present application clearer and more understandable, the portable waterless milk warmer is further described below in combination with the drawings, and the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0031] As shown in Figure 1 , Figure 2 , a portable waterless milk warmer includes a seat body 100, the top of the seat body 100 has an upper open groove 101, the groove 101 forms a containing space for placing a milk bottle and other milk storage containers, the containing space can adapt to most of the milk bottle shapes on the market, and the space should not be too large. Among them, the seat body 100 is composed of upper and lower shells made of plastic material, which has a cavity inside, and an electromagnetic generating device 200 is arranged in the cavity. Here, the electromagnetic generating device 200 as prior art includes a control circuit 201, a power supply 202 and an electromagnetic emitting end 203, the power supply 202 and the electromagnetic emitting end 203 are respectively electrically connected with the control circuit 201. The power supply 202 can be external power or a rechargeable lithium battery, and the electromagnetic emitting end 203 is a group of conductive coils. A magnetic induction heating body 300 is arranged on the outer surface of the milk bottle 900 used in cooperation with the device, and the magnetic induction heating body 300 is preferably a metal with good magnetic conductivity or a medium containing metal powder. When the milk bottle 900 is placed in the containing space of the seat body 100, the electromagnetic emitting end 203 of the electromagnetic generating device 200 corresponds to the position of the magnetic induction heating body 300 and matches it. When the electromagnetic generating device 200 works, the electromagnetic emitting end 203 generates an alternating magnetic field, the magnetic induction heating body 300 induces the magnetic field and generates heat, and the heat is transmitted to the liquid (such as milk) in the milk bottle 900 to realize the function of warming the milk.

[0032] Since the device is mainly used in the scene of warming milk, and most of the milk bottles on the market are columnar, the electromagnetic emitting end 203 is a group of coils that can be spaced around the outer sidewall of the milk bottle 900, and the coil is located in the inner cavity of the sidewall of the groove 101 to realize isolation. Correspondingly, the magnetic induction heating body 300 is connected to the side wall of the milk bottle 900. In this way, the magnetic induction heating body 300 has a larger contact surface with the milk bottle and can fully utilize the magnetic field work to improve the efficiency of heating the milk.

[0033] In some embodiments, the magnetic induction heating body 300 includes a first magnetic induction heating body 310 connected to the side wall of the milk bottle 900, and the first magnetic induction heating body 310 is a structural layer 301. For example, the structural layer 301 is a metal coating or a metal plating layer attached to the side wall of the milk bottle 900 by spraying or electroplating.

[0034] In other embodiments, the first magnetic induction heating body 310 is a flexible body, which can also be connected to the side wall of the milk bottle 900 in a detachable manner. Here, the flexible body refers to a sheet body that can have a certain bending elasticity and at the same time has a magnetic induction function, such as a flexible metal film or a sheet body with conductive materials such as metal powder. Specifically, one of the detachable structures is as follows: Figure 3As shown, one side (inner side) of the first magnetic induction heating body 310 is provided with a negative pressure suction disc 302, which can be made of soft materials such as silica gel or rubber. The negative pressure suction disc 302 is an array of multiple negative pressure suction discs arranged along the inner wall of the first magnetic induction heating body 310. The wall thickness of each negative pressure suction disc 302 should not be too thick, and the opening should not be too large, so as to prevent poor heat conduction and poor air tightness of the first magnetic induction heating body 310 when it is bent and attached to the side wall of the feeding bottle 900. When the first magnetic induction heating body 310 is attached to the side wall of the feeding bottle 900 along its length direction, the negative pressure suction disc 302 is pressed to discharge the excess gas in its cavity to form a negative pressure effect. Under the common negative pressure suction of multiple negative pressure suction discs 302, the first magnetic induction heating body 310 can be tightly connected to the side wall of the feeding bottle 900. Since the temperature of the device during use should not be too high, the air in the negative pressure suction disc 302 is not heated too much when the first magnetic induction heating body 310 is heated, which does not affect its negative pressure suction force too much, so that the phenomenon of the first magnetic induction heating body 310 falling off during device operation does not occur.

[0035] Another detachable structure is as follows: Figure 4 As shown, one side (inner side) of the first magnetic induction heating body 310 has an adhesive layer 304, which can be composed of adhesive glue. The first magnetic induction heating body 310 is connected to the side wall of the feeding bottle 900 through the adhesive layer 304 to realize detachable connection.

[0036] Another detachable structure is as follows: Figure 5 As shown, the two ends of the first magnetic induction heating body 310 are respectively provided with a hook-faced magic tape 305 and a fuzzy-faced magic tape 306. When the first magnetic induction heating body 310 is wrapped around the side wall of the feeding bottle 900, the detachable connection between the first magnetic induction heating body 310 and the feeding bottle 900 is realized under the interaction of the hook-faced magic tape 305 and the fuzzy-faced magic tape 306.

[0037] As shown in the figure, Figure 6 The first magnetic induction heating body 310 can also have a ring structure, i.e. a ring-shaped flexible body 303, which has elastic deformation capability on the ring path. That is, the caliber of the first magnetic induction heating body 310 has elastic deformation capability. For example, the ring-shaped flexible body 303 itself has elastic deformation capability, or a section or multiple sections of elastic body with elastic extension capability are separately provided on the ring path. When it is sleeved on the outer wall of the feeding bottle 900, it is tightly attached to the feeding bottle 900 through its own elastic deformation, and when it is removed, it can be realized by stretching the ring-shaped flexible body 303 through external force.

[0038] The detachable first magnetic induction heating element 310 allows it to be used with different sized baby bottles within a certain range, thus improving the applicability of the device. Furthermore, multiple detachable first magnetic induction heating elements 300 can be provided, with no limit on their shape, facilitating DIY design by customers. The first magnetic induction heating element 300 can be connected to any position on the side wall of the baby bottle, increasing the fun of using the device.

[0039] To meet the temperature control requirements for warming milk, a temperature sensor 102 for measuring the liquid inside the bottle 900 is also provided at the bottom of the groove 101. The temperature sensor 102 is electrically connected to the control circuit 201 inside the base 100. When the temperature signal emitted by the temperature sensor 102 is greater than the threshold set in the control circuit 201, the control circuit 201 controls the electromagnetic transmitter 203 to stop working. Here, the temperature sensor 102 can be a non-contact infrared temperature sensor.

[0040] like Figure 7 As shown, based on the above structure, the magnetic induction heating element 300 also includes a second magnetic induction heating element 320 located on the bottom wall of the baby bottle 900. The second magnetic induction heating element 320 has the same structure as the first magnetic induction heating element 310.

[0041] In addition, if the second magnetic induction heating element 320 is not provided on the bottom wall of the bottle 900, a third magnetic induction heating element 330 can be provided on the bottom surface of the groove 101. The third magnetic induction heating element 330 can be connected to the bottom surface of the groove 101 using the structure of the above-mentioned structural layer 301. Of course, the third magnetic induction heating element 330 should avoid the detection path of the temperature sensor 102.

[0042] This device improves milk warming efficiency by incorporating an electromagnetic generator 200 and a magnetic induction heater 300. Under the influence of an induced magnetic field, the magnetic induction heater generates heat and directly transfers it to the liquid in the bottle.

[0043] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
