Description

Technical Field

[0001] The utility model belongs to the technical field of electric kettles, and particularly relates to a temperature controller of an electric kettle with a water filling function. Background Art

[0002] In traditional electric kettles with a water filling function, the water pump is generally installed on the base, making the base structure larger. Generally, it can only be installed on a table or a tea table during factory production. It is very difficult to modify an ordinary table or tea table to install the electric kettle, making the modification inconvenient. For example, an electric kettle with a combined automatic water filling structure and a temperature controller disclosed in the patent No. CN204146860U has a large power socket size that exceeds the size of the kettle. If modification is needed, a large hole needs to be cut in the existing table, which undoubtedly incurs high costs and is inconvenient, and will also affect the strength of the table. The industry has also considered setting the water pump in the hot water kettle in this case, but the problems of water filling and the over-large water path size in the hot water kettle cannot be solved. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is how to design the automatic water filling part in the hot water kettle so that the base of the hot water kettle can be made smaller and the size of the water path part in the hot water kettle will not be too large.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A temperature controller with a water filling function comprises an upper coupler and a lower coupler. Both the upper coupler and the lower coupler are provided with circuit parts. When the upper coupler is coupled with the lower coupler, the two circuit parts are in contact and conduct electricity. A water pump connecting piece is installed in the upper coupler. The water pump connecting piece includes a water inlet end, a water outlet end and a water pump connecting end. A first sealing assembly is arranged at the water inlet end of the water pump connecting piece, and a second sealing assembly is arranged at the water outlet end of the water pump connecting piece.

[0006] Preferably, the water pump connecting end of the water pump connecting piece has two channels, the two channels are respectively communicated with the water inlet end and the water outlet end of the water pump connecting piece, and the two channels are respectively connected to the water inlet and outlet of the water pump through pipelines or directly.

[0007] Preferably, the first sealing assembly includes a flexible sleeve and a first spherical ball. The flexible sleeve is embedded at the water inlet port of the water pump connecting piece. The first spherical ball is movably arranged inside the water inlet end, and the first spherical ball is arranged above the flexible sleeve. When the first sealing assembly is in a sealed state, the first spherical ball abuts against the flexible sleeve.

[0008] Preferably, a spring is further arranged inside the water inlet end. One end of the spring abuts against the first spherical ball, and the other end abuts against the inner wall of the upper end of the water inlet end.

[0009] Preferably, the flexible sleeve is made of silica gel, and the upper end of the flexible sleeve gradually decreases in diameter from top to bottom to form a tapered hole. The diameter of the first spherical ball is larger than the minimum diameter of the tapered hole, and the diameter of the first spherical ball is 0-2 mm smaller than the diameter of the water inlet end.

[0010] Preferably, the second sealing assembly includes a water inlet cap. The upper end of the water inlet cap extends into the inner cavity of the kettle, and a sealing ring is provided between the lower end of the water inlet cap and the water outlet end of the water pump connecting piece.

[0011] Preferably, a bimetal mounting plate is provided on the upper coupler. A through hole for the water pump connecting piece to pass through is provided on the bimetal mounting plate. The upper end of the water pump connecting piece penetrates through the bimetal mounting plate and protrudes above the upper surface of the bimetal mounting plate. A ring groove for the upper end of the water pump connecting piece to be embedded is provided on the water inlet cap, and the sealing ring is arranged in the ring groove.

[0012] Preferably, the water pump connecting piece is an integrally formed one-piece structure.

[0013] Preferably, the water pump connecting piece is made of plastic or metal.

[0014] Preferably, a second spherical ball is provided at the channel where the upper end of the water inlet cap communicates with the hot water kettle. The second spherical ball is in sealing cooperation with the water inlet cap when the water pump stops pumping water. When the water pump pumps water, the water pressure pushes open the second spherical ball to create a gap for the water flow to pass through between the second spherical ball and the water inlet cap.

[0015] The beneficial effects of the present utility model are as follows: The water pump of the present utility model is arranged inside the hot water kettle. Through the setting of the water pump connecting piece, the pipeline inside the hot water kettle is simple, occupying less space.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1-4 , as shown in the figure, a temperature controller with a water supply function is shown. It is a temperature controller for an electric kettle with a water supply function whose base is fixed on a tea table or a table, and is also called a coupler in the industry. It is used to connect the power supply and water source of the kettle. The temperature controller includes an upper coupler 1 and a lower coupler 2. Both the upper coupler 1 and the lower coupler 2 are provided with circuit parts. When the upper coupler 1 is coupled with the lower coupler 2, the two circuit parts are in contact and conduct. The circuit parts of the upper coupler 1 and the lower coupler 2 are prior art and will not be elaborated here. In this embodiment, the water pump for pumping the water from the water source to the hot water kettle is installed inside the hot water kettle (not shown in the figure). This structure only installs the water pump inside the hot water kettle and has no technical difficulties, belonging to conventional technology and will not be elaborated here. In addition, a water inlet pipe 21 is provided on the lower coupler. It should be noted that a water pump connector 11 is installed inside the upper coupler 1. The water pump connector 11 includes a water inlet end 111, a water outlet end 112, and a water pump connection end 113. A first sealing assembly is provided at the water inlet end 111 of the water pump connector 11, and a second sealing assembly is provided at the water outlet end 112 of the water pump connector 11. The water pump connection end 113 of the water pump connector 11 has two channels, and the two channels are respectively connected to the water inlet end 111 and the water outlet end 112 of the water pump connector 11. The two channels are respectively connected to the water inlet and outlet of the water pump through pipes or directly. The original temperature controller with a water supply function also has a water pipeline inside. For example, the water outlet pipe in a double-sealed temperature controller with a water supply function disclosed in the publication number CN113838704A is a water pipeline, but it is a vertically through type with a relatively simple structure. In this embodiment, the water pump connector 11 replaces the original pipeline, and only has two additional channels for connecting the water pump on the side. The overall size is almost exactly the same as the original one. Because there is spare space inside the original hot water kettle, the water pump of this application can be installed in the original spare space. Therefore, the size of the overall hot water kettle has not changed. On the contrary, the size of the base part of the hot water kettle has been greatly reduced, making the modification more convenient and easier to implement, and having a wide range of adaptability.

[0024] In this embodiment, the first sealing assembly includes a flexible sleeve 12 and a first spherical ball 13. The flexible sleeve 12 is embedded at the mouth of the water inlet end 111 of the water pump connector 11. The first spherical ball 13 is movably arranged inside the water inlet end 111. The first spherical ball 13 is arranged above the flexible sleeve 12. When the first sealing assembly is in a sealed state, the first spherical ball 13 abuts against the flexible sleeve 12. The flexible sleeve 12 is made of silica gel. In existing thermostats, there is also such a flexible sleeve 12 made of silica gel. For example, in a double-sealed thermostat with a water filling function disclosed in the patent with the publication number CN113838704A, the sealing sleeve is equivalent to the flexible sleeve 12 in this embodiment. Of course, the flexible sleeve 12 can also be designed into other structures, which are all within the protection scope of this application. Therefore, its specific structure will not be elaborated in detail here.

[0025] In this embodiment, in order for the first spherical ball 13 to better seal with the flexible sleeve 12, a spring 14 is further arranged inside the water inlet end 111 in this embodiment. One end of the spring 14 abuts against the first spherical ball 13, and the other end abuts against the inner wall of the upper end of the water inlet end 111. In order for the first spherical ball 13 to better seal with the flexible sleeve 12, the flexible sleeve 12 is designed to be made of silica gel material in this embodiment, and the diameter of the upper end of the flexible sleeve 12 gradually decreases from top to bottom to form a tapered hole. The diameter of the first spherical ball 13 is larger than the minimum diameter of the tapered hole, and the diameter of the first spherical ball 13 is 0 - 2 mm smaller than the diameter of the water inlet end 111, further ensuring that the first spherical ball 13 can seal well with the flexible sleeve 12.

[0026] In order to seal between the upper end of the water pump connector 11 and the kettle, the second sealing assembly in this embodiment is designed to include a water inlet cap 15. The upper end of the water inlet cap 15 extends into the inner cavity of the kettle. There is a sealing structure between the water inlet cap 15 and the inner cavity shell of the kettle. This sealing structure is a prior art and will not be elaborated in detail here. It should be noted that a sealing ring 17 is provided between the lower end of the water inlet cap 15 and the water outlet end 112 of the water pump connector 11. A bimetal mounting plate 16 is provided on the upper coupler 1. A through hole for the water pump connector 11 to pass through is provided on the bimetal mounting plate 16. The upper end of the water pump connector 11 penetrates through the bimetal mounting plate 16 and protrudes above the upper surface of the bimetal mounting plate 16. A ring groove 151 for the upper end of the water pump connector 11 to be embedded is provided on the water inlet cap 15. The sealing ring 17 is arranged in the ring groove 151. An annular protrusion 152 is provided in the middle of the ring groove 151 of the water inlet cap 15. This protrusion is inserted into the water outlet end 112 of the water pump connector 11 to form multi-point positioning. In this embodiment, the water pump connector 11 is an integrally formed one-piece structure. The water pump connector 11 is made of plastic or metal material, and plastic material is preferably used in this embodiment.

[0027] Embodiment Two

[0028] As another preferred embodiment, the difference between this embodiment and the first embodiment is that: in this embodiment, a second spherical ball 18 is provided at the channel where the upper end of the water inlet cap 15 communicates with the hot water kettle. The second spherical ball 18 is in sealing cooperation with the water inlet cap 15 when the water pump stops pumping water. When the water pump pumps water, the water pressure pushes open the second spherical ball 18 to create a gap through which the water supply flows between the second spherical ball 18 and the water inlet cap 15. The setting of the second spherical ball makes the upper end of the water inlet cap sealed when there is no water pumping, preventing the hot water in the hot water kettle from flowing into the water pump and preventing the high-temperature hot water from damaging the internal parts of the water pump, thereby improving the service life of the water pump.
