Detailed Description

In order to make the technical solution of the present invention better understood, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiments.

Referring to fig. 1 to 4, the embodiment provides a heating cup, which includes a cup 50 and a heating assembly, the heating assembly is located at the bottom of the cup 50, and the cup 50 is heated by the heating assembly, wherein the heating assembly includes a heating element and a control circuit board 70 connected with the heating element, and a shell 80 and a cup cover 90 located at an opening of the cup 50 cover the outside of the cup 50. The heating cup adopts a plug power supply mode to supply power, a change-over switch component is arranged at the bottom of the cup body 50 and comprises a plug, a socket 10 and a change-over switch 20, the plug comprises a direct current plug 30 and an alternating current plug 40, the direct current plug 30 is externally connected with a direct current power supply or a direct current adapter, the alternating current plug 40 can be directly connected with alternating current power supply, and the socket 10 is compatible with the direct current plug 30 and the alternating current plug 40. The switch 20 is used for switching direct current and alternating current power supply, a toggle slide block 21 is arranged on the switch 20, the socket 10 is connected with a control circuit board 70 through the switch 20, wherein the heating element is arranged at the bottom end of the cup body 50, and the structure of the heating element is not shown in the drawing.

In the embodiment, the control circuit board 70 is provided with a dc power supply circuit and an ac power supply circuit inside, and the slider 21 is toggled to control the connection between the dc power supply circuit and the ac power supply circuit and the socket 10, so that when the dc power supply is needed, the slider 21 is toggled to move to the right side, and when the ac power supply is needed, the slider 21 is toggled to move to the left side.

In order to avoid that the toggle sliding block 21 can still be operated when the plug is plugged, a first limiting block 31 is arranged on the direct current plug 30, a second limiting block 41 is arranged on the alternating current plug 40, when the direct current plug 30 is plugged with the socket 10 for power supply, the first limiting block 31 limits the toggle sliding block 21 to be incapable of moving, and at this time, the change-over switch 20 is in a direct current power supply mode, as shown in fig. 3; when the ac plug 40 is plugged into the socket 10 for power supply, the second limiting block 41 limits the toggle slider 21 to make it unable to move, and the switch 20 is in the ac power supply mode at this time, as shown in fig. 4, that is, the toggle slider 21 cannot be operated after the socket 10 is plugged into different plugs, so as to limit and select the corresponding power supply mode, thereby avoiding the power supply mode being switched in the plugging process to cause the mismatching of the power supply circuit, and being beneficial to protecting the power supply circuit.

Referring to fig. 5 and 6, in this embodiment, the socket 10 is an 8-shaped socket, the conductive pins 11 are disposed in the socket 10, the dc plug 30 and the ac plug 40 are both 8-shaped plugs matched with the socket 10, the dc plug 30 is disposed with first conductive holes 32 corresponding to the conductive pins 11, and the ac plug 40 is disposed with second conductive holes 42 corresponding to the conductive pins 11. The first stopper 31 is provided on the sidewall of the dc plug 30, the second stopper 41 is provided on the sidewall of the ac plug 40, the switch 20 is fixed above the socket 10, and the switch 20 may be provided at the bottom of the socket 10. The connection position of the switch 20 and the socket 10 can satisfy that the socket 10 can block the toggle sliding block 21 from being plugged by corresponding limiting blocks of different plugs, so that the toggle sliding block 21 cannot move.

In addition, the socket 10 can adopt a delta-shaped socket with a ground wire, the direct current plug 30 and the alternating current plug 40 are both delta-shaped plugs matched with the delta-shaped socket, and considering that the delta-shaped plugs have an upward protruding structure, therefore, the limit blocks are arranged on the lower sides of the delta-shaped plugs, namely, the first limit block 31 is arranged on the lower side of the delta-shaped direct current plug 30, the second limit block 41 is arranged on the lower side of the delta-shaped alternating current plug 40, and the change-over switch 20 is arranged below the socket 10, so that the limit functions of the first limit block 31 and the second limit block 41 are not limited by the delta-shaped plug structure.

Wherein, first stopper 31 is the arch of vertical extension and with the integrative injection moulding of direct current plug 30, second stopper 41 is the arch of vertical extension and with the integrative injection moulding of alternating current plug 40, the bellied distance that highly is greater than socket 10's jack and stir between the slider 21 on two plugs, like this, first stopper 31 and second stopper 41 can satisfy and play the effect that blocks when pegging graft and stir the slider 21 and remove. Of course, the first limiting block 31 and the second limiting block 41 are not limited to the vertical direction extension of this embodiment, and may be disposed obliquely, so long as the corresponding limiting blocks are limited to the toggle sliding block 21 when the socket 10 is plugged with different plugs, so that the toggle sliding block 21 cannot move, and both belong to the same technical means.

In this embodiment, as shown in fig. 3, when the direct current is supplied, the toggle sliding block 21 moves to the right side, the first limit block 31 is located at the left end of the direct current plug 30, and the first limit block 31 is located at the left side of the toggle sliding block 21 after the direct current plug 30 is inserted into the socket 10; as shown in fig. 4, when the alternating current is supplied, the toggle slider 21 moves to the left, the second limiting block 41 is located at the right end of the alternating current plug 40, and the second limiting block 41 is located at the right side of the toggle slider 21 after the alternating current plug 40 is inserted into the socket 10. It is easy to understand that when the toggle sliding block 21 is located on the left side, the toggle sliding block is switched to the ac power supply mode, and the first limiting block 31 is abutted to the position of the toggle sliding block 21, so that the dc power plug 30 cannot be inserted into the socket 10; similarly, when the toggle sliding block 21 is located on the right side, the second limiting block 41 is abutted to the position of the toggle sliding block 21, and the ac electrical plug 40 cannot be inserted into the socket 10, so that a wrong plug is avoided.

Further, referring to fig. 3 and 4, in order to prevent the dc plug 30 or the ac plug 40 from being inserted into the socket 10 in a reversed manner, that is, the first stopper 31 or the second stopper 41 faces downward, the socket 10 is fixed on the mounting bracket 60 at the bottom of the cup 50, the bottom end of the mounting bracket 60 is connected to the bottom plate 61 through the upright post 62, and the socket 10 is tightly fixed on the bottom plate 61, so that the first stopper 31 and the second stopper 41 do not have enough space to insert, thereby limiting the insertion of the plug in the reversed manner and improving the protection performance. In addition, the housing 80 is provided with an opening corresponding to the diverter switch assembly.
