[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4A liquid heating device that can be powered by a battery includes a heating device body 1 and a battery compartment 2 that is detachably connected to the heating device body 1, and the battery compartment 2 has a connection state relative to the heating device body 1 and a detachment state relative to the heating device body 1.

[0028] The battery compartment 2 has at least two power terminals 3, and the heating device body 1 has corresponding milk-warming terminals 4. When the battery compartment 2 is connected, the power terminals 3 come into contact with the corresponding milk-warming terminals 4, enabling the battery 203 in the battery compartment to supply power to the electrical components of the heating device body 1. In other words, at least one power terminal is a positive terminal, and at least one power terminal is a negative terminal.

[0029] Specifically, the battery compartment 2 has a connection end 201 for detachably connecting the battery compartment to the heating device body, and the heating device body 1 has a corresponding joining end 101 detachably connected to the connection end, so that the battery compartment forms a connection state relative to the heating device body and a detached state relative to the heating device body.

[0030] In some embodiments, the top of the heating device body 1 has a joint 102 that is detachably connected to the bottle mouth of the user's feeding bottle, such as by screwing it to the bottle mouth with an external thread in a more common screw connection manner.

[0031] In some embodiments, when the heating device body 1 is connected to the bottle mouth of a user's milk bottle through the joint and used to warm milk, the heating device body 1 can also be called a milk warmer body. The liquid heating device corresponds to a milk warmer.

[0032] In some embodiments, the heating device body 1 has an electric heater 103 corresponding to the joint 102. Figure 1 As shown, the electric heater 103 can be, for example, a heating plate. After the bottle mouth of the user's feeding bottle is connected to the joint, the heating plate can contact and heat the milk in the feeding bottle.

[0033] In some embodiments, the joining end 101 is located at the bottom of the heating device body 1, and the connecting end 201 is located at the top of the battery compartment 2. When the battery compartment 2 is connected to the heating device body 1, the battery compartment 2 is correspondingly at the bottom of the heating device body 1, and the battery compartment 2 forms the base of the milk warmer, thereby increasing the bottom stability during use.

[0034] When the milk warmer terminal 4 is arranged on the bottom surface of the bottom of the heating device body 1, the bottom of the heating device body 1 may preferably be provided with a downwardly arranged protective frame 104. The protective frame 104 can protect the milk warmer terminal 4 when the heating device body 1 (without the battery compartment connected) is placed on the work surface, thereby reducing the possibility of the milk warmer terminal 4 directly contacting the work surface or reducing the possibility of the milk warmer terminal 4 contacting the water stains remaining on the work surface.

[0035] In this case, the protection frame 104 can also be called a support, which is used to support the heating device body 1 together with the milk warmer terminal 4.

[0036] Preferably, the battery compartment 2 has a positioning groove 202 corresponding to the protection frame 104 , and when the battery compartment 2 and the heating device body 1 are engaged up and down, the protection frame 104 correspondingly enters the positioning groove 202 downward.

[0037] In some embodiments, the power terminal 3 can be a metal sheet, a spring sheet type terminal, a spring pin type terminal, a gold finger, etc. arranged on the top of the battery compartment 2; the milk warmer terminal 4 can be a spring pin type terminal, a gold finger, a metal sheet, a spring sheet type terminal, etc. arranged on the bottom of the heating device body 1.

[0038] In this embodiment, the detachable connection between the connecting end 201 and the engaging end 101 includes a magnetic connection.

[0039] In some embodiments, a first magnetic component is installed on the connecting end near the joining end, and a second magnetic component that cooperates with the first magnetic component is installed on the joining end near the connecting end. At least the first magnetic component or the second magnetic component is a magnet.

[0040] If the first magnetic member is a magnet, the second magnetic member can be a non-magnetic component such as an iron block that can be magnetically attracted by the first magnetic member; or if both the first and second magnetic members are magnets, when connecting, simply bring the connecting end of the battery compartment close to the mating end to complete the connection.

[0041] In this embodiment, the detachable connection between the connecting end 201 and the engaging end 101 includes a screw connection.

[0042] For example, the connection end has a screw thread and the connection end has a corresponding connection screw hole; or Figure 2 、 3 As shown, the connecting end 201 has a screw-on male buckle 2011, and the coupling end 101 has a corresponding screw-on female buckle 1011; when connecting, first move the connecting end 201 of the battery compartment upward close to the coupling end 101 and move it to the screw-on position, and then tighten it to complete the convenient connection.

[0043] When the above-mentioned rotation connection is selected and the protective frame 104 and the positioning slot 202 are provided, the protective frame 104 is configured to be able to perform a certain degree of follow-up rotation in the above-mentioned positioning slot 202 , for example, the protective frame 104 is an annular protective frame.

[0044] In some embodiments, the rotational connection and the magnetic connection can be provided at the same time, and the magnetic attraction position can be made to correspond to the rotational connection position during design.

[0045] In this embodiment, the connection mode between the connection end and the engagement end is a detachable plug-in connection, a detachable snap-in connection, or other convenient detachable connection mode.

[0046] In some embodiments, the heating device body 1 is provided with a PCBA, and is configured with a power supply circuit module and a control unit.

[0047] In some embodiments, the heating device body 1 is further provided with a charging interface 105 , which can be used to supply power with commercial electricity, or to charge the battery 203 in the battery compartment through the charging interface 105 .

[0048] In some embodiments, a snap-action thermostat is connected in series to one of the power terminal 3 of the battery compartment. For example, a snap-action thermostat is connected in series to the power terminal that serves as the negative terminal. The snap-action thermostat can protect the battery compartment from over-temperature, making it safer to use. Moreover, with the series snap-action temperature control, the battery output only has positive and negative poles, eliminating the need for additional auxiliary temperature control circuits such as NTC. If a processor is provided in the battery compartment, the circuit structure becomes complex. If the control unit is not provided in the battery compartment, but the NTC signal is electrically connected to the control unit of the milk warmer body, then in addition to the positive and negative terminals of the battery, the battery compartment also needs to be provided with corresponding NTC signal terminals, both of which lead to reduced safety and increased costs.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
