Detailed Description

As a specific embodiment, the heating base of the present invention includes a carrier 1 with a power connection port 11 on a side surface, and a heating plate 18 and/or an electric coupler 19 on a top end surface of the carrier 1.

The heating plate 18 is an electrical member for generating heat, such as a sheet of a PTC heater, an electromagnetic generating device, or the like.

The electric coupler 19 is a device for coupling and supplying power to an electric kettle or the like (not shown in the drawings) placed on the electric coupler 19.

The power connection 11 is an electrical connection for supplying power to the heating base, such as for connecting to mains electricity to provide 220V ac power. In a specific embodiment, an electrical converter 119 is electrically connected to the power interface 11 to supply a direct current of 5V or the like to a control device 3 described later and supply an alternating current to the heating plate 18 and/or the electric coupler 19 via the control device 3.

In one specific embodiment, the heating plate 18 and the electric coupler 19 are coaxially disposed.

The cross section of the carrier 1 is rectangular as a whole, and may be circular, elliptical or other polygonal.

The carrier 1 is provided with a control device 3, and the power interface 11, the heating plate 18 and/or the electric coupler 19 are respectively electrically connected with the control device 3. The control device 3 is a device used for realizing electric control in the prior art, such as a circuit board, a PLC controller, and the like. As a specific embodiment, the electrical conversion device 119 for converting between ac and dc may be integrated with the control device 3.

As one specific embodiment, the carrier 1 is hollow so as to be box-shaped as a whole. Adjustment electric elements 29, control devices 3, and the like, which will be described later, can be accommodated in the carrier 1.

The rear side of the top end surface of the carrier 1 is hinged with an adjusting device 2, and the adjusting device 2 is connected with an adjusting electric part 29 electrically connected with the control device 3. For example, the control electronics 29 are fixedly connected to the control device 2. The adjustment electric component 29 is a potentiometer or the like, such as a potentiometer or the like, which can output a signal by rotation.

The adjusting device 2 is provided with an extension rod 21, and the front end of the extension rod 21 extends to the front side beyond the top end face of the carrier 1. The rear side of the top end face of the carrier 1 refers to a central plane passing through the heating disk 18 and the axis of the electric coupler 19 and located on the side of the central plane close to the power receiving port 11. Conversely, the front side of the top end face of the carrier 1 refers to a central plane passing through the heating plate 18 and the axis of the electric coupler 19 and located on the side of the central plane away from the power receiving port 11.

As a specific embodiment, the top end surface of the carrier 1, on which the front end of the extension rod 21 is directly opposite (in other words, the area corresponding to the projection on the top end surface of the carrier 1), is provided with the mark area 12, and the mark area 12 is provided with a mark. The identification area 12 is provided with identifications of '45 degrees, 85 degrees, 100 degrees', 'big fire, small fire, closing, heat preservation' and the like. So as to confirm the position of the extension bar 21. As a specific embodiment, one end of the extension rod 21 is provided with a knob.

As a specific embodiment, the front side of the top end face of the carrier 1 is provided with a main electric switch 31 and/or a function switch 32, and the main electric switch 31 and/or the function switch 32 are electrically connected with the control device 3. The function switch 32 is used to implement a function other than heating of the heating plate 18 and/or the electric coupler 19 by the control device 3, for example, to implement a water adding function by controlling a solenoid valve (not shown in the drawings) of a faucet. The total electric switch 31 is used to effect the control of the total electricity either directly or indirectly through the control device 3.

The working principle is that before use, the carrier 1 is placed on a re-table or the like so that the user is in front of the carrier 1 and the front side of the top end face of the carrier 1 is close to the user. In this case, the power supply line such as commercial power is connected to the carrier 1 from the power receiving port 11 on the rear side surface of the carrier 1, and the power supply line such as commercial power does not interfere with the use of the heating base by the user.

When the heating plate 18 and/or the electric coupler 19 needs to be adjusted, the front end of the extension rod 21 is shifted, so that the adjusting device 2 rotates, the adjusting electric part 29 sends a signal changed by the rotation to the control device 3, and the control device 3 controls the heating plate 18 and/or the electric coupler 19 to change the state.

When heating plate 18 and/or electrical coupler 19 are adjusted, the user's hand may extend a short distance, facilitating adjustment of heating plate 18 and/or electrical coupler 19.

As a specific embodiment, the control device 3 is arranged on the rear side of the carrier 1 and is located entirely within the rear region of the carrier 1. The circuit structure of the heating base is relatively simple, the function of the control device 3 is relatively simple, and therefore the volume is small, and the projection of the control device 3 on the top end surface of the carrier 1 is completely positioned in the rear area of the carrier 1 when the control device 3 is a circuit board. In view of electrical safety, the wires between the power connection port 11 and the control device 3 must be thicker wires, which are less expensive than the wires between the control device 3 and the main electrical switch 31, plus the wires between the control device 3 and the function switch 32; thereby can reduce manufacturing cost through reasonable wiring. Of course, the production costs can of course also be reduced for embodiments in which the total electrical switch 31 and the functional switch 32 are not present.

The electric wire between the electric interface 11 and the control device 3 is short, which is beneficial to reducing the cost.

In a specific embodiment, the adjusting device further includes a speed increasing device 22, and the adjusting device 2 is connected to the adjusting electrical component 29 through the speed increasing device 22. A small rotational angular velocity is input to the input speed increasing device 22, and a large rotational angular velocity is output from the speed increasing device 22, thereby increasing the rotational linear velocity. The adjustment electrical component 29 can rotate by a larger angle by pulling the extension rod 21 by a smaller angle, and the adjustment electrical component 29 does not need to select an electrical component with higher precision, such as a potentiometer with higher precision, in other words, the adjustment precision is improved, or the adjustment electrical component 29 can select an electrical component with lower precision, such as a potentiometer with lower precision, so that the production cost is reduced (generally, the cost of adding two gears is lower than the cost increased by selecting a potentiometer with higher precision).

In a specific embodiment, the speed increasing device 22 includes a first speed increasing gear 221 and a second speed increasing gear 222 that are engaged with each other, a diameter of a reference circle of the first speed increasing gear 221 is smaller than a diameter of a reference circle of the second speed increasing gear 222, and the first speed increasing gear 221 and the second speed increasing gear 222 are connected to the adjustment electric component 29 and the adjustment device 2, respectively.

In a specific embodiment, the length of the extension rod 21 (the distance from one end of the extension rod 21 to the rotation axis of the adjusting device 2) is the extension rod length 211, and the diameter of the reference circle of the second speed-increasing gear 222 is smaller than the extension rod length 211. When one end of the control device 3 is shifted, a larger moment can be provided, so that the control device 3 is shifted more easily and conveniently.
