Description

Technical Field

[0001] The utility model relates to the field of electrical connectors, in particular to a connector with a weighing function. Background Art

[0002] Existing electric kettles generally consist of a base and a kettle body. The base is provided with a control circuit, and a heating element is provided at the lower part of the kettle body. The kettle body and the control circuit are connected through a coupler. The kettle body is also provided with a water level sensor. When in use, just place the kettle body on the base, and the control circuits of the base and the kettle body can be connected. The water level sensor and the water pump in the base can be linked to control the maximum water level in the kettle body. However, the electric kettle with this structure has the following defects:

[0003] Defect 1: The signal output end of the water level sensor in the kettle body is commonly connected to the ground wire of the electric kettle. This setting method causes the water body in the kettle body to inevitably carry a weak current. Existing electric kettles on the market have certain potential safety hazards during use and do not meet the current safety regulations requirements for electric kettles.

[0004] Defect 2: Even some electric kettles are equipped with a water level sensor, but this water level sensor only monitors whether there is no water or a very low water level in the kettle body. After the user touches the boiling water command, when it is judged that there is no water or a very low water level in the kettle body, the water pump is automatically started to add water to the kettle body. Therefore, when there is a certain amount of water in the kettle body and the user manually triggers the water addition command, the electric kettle will only add water to the kettle body according to the preset water addition time. Finally, when the original amount of water in the kettle body is added to the added amount of water, it is easy to cause the water to overflow from the kettle mouth or spout, thus affecting the user experience.

[0005] Defect 3: Since the water level sensor is an external part and is mostly assembled on the heating plate at the bottom of the kettle body, the heating plate must be perforated, which seriously affects the appearance. After long-term use, it also affects the sealing performance and is not easy to clean. At the same time, the price of the water level sensor is relatively high, which affects the manufacturing cost.

[0006] Therefore, the applicant provides a new technical solution to solve the above multiple defects for consumers to choose and use by improving and perfecting the electrical connector and combining the above existing technologies. Summary of the Invention

[0007] The purpose of the utility model is to solve the above existing problems and provide a connector with a weighing function that has a simple and reasonable structure.

[0008] A connector with a weighing function, comprising a connection base and a connector. The connector is movably assembled above the connection base and can move up and down relative to the connection base. A sensor support frame is connected below the connector, and a movable sensor for electrically connecting with a control system is connected to the sensor support frame. A contact support frame is connected below the connection base, and a fixed contact point is arranged on the contact support frame below the movable sensor. The movable sensor moves up and down with the connector and movably presses on the fixed contact point. The connector sinks or rises according to different bearing weights, so that the movable sensor increases or decreases the acting force applied to the fixed contact point, causing the movable sensor to deform and its resistance value to change.

[0009] The object of the present utility model can also be solved by adopting the following technical measures:

[0010] As a more specific solution, the movable sensor is a full crossbeam type sensor, which includes a fixed connection frame, a load-bearing deformation frame connected to the fixed connection frame, a load-bearing deformation part connected to the load-bearing deformation frame, and a strain gauge connected to the load-bearing deformation frame. The fixed connection frame is assembled and connected with the sensor support frame, and the load-bearing deformation part presses on the fixed contact point.

[0011] As a further solution, a upper threaded hole is opened on the strain gauge, and a connection through hole corresponding to the upper threaded hole is opened on the fixed contact point. The fixed contact point and the strain gauge are firmly connected by a screw passing through the connection through hole and the upper threaded hole.

[0012] As a further solution, the connection base includes a support disc and a fixed disc. The support disc is firmly connected below the fixed disc, and a clamping gap for clamping an installation panel is formed at the edge between the two. The contact support frame is fixedly connected below the support disc, and the fixed contact point is arranged at the center of the support disc through the contact support frame.

[0013] As a further solution, the contact support frame includes several first connection columns vertically extending downward from the support disc and a balance beam firmly connected to the bottom ends of the several first connection columns. The center of the balance beam forms a fixed contact point by upward stretching.

[0014] As a further solution, the sensor support frame includes a connection bottom plate placed directly below the connector. The movable sensor is fixed on the lower side of the connection bottom plate. Several connection support feet are circumferentially and evenly distributed on the upper side of the connection bottom plate. Several second connection columns extend corresponding to the number of the connection support feet on the bottom surface of the connector. The connection support feet are firmly connected to the bottom ends of the second connection columns.

[0015] As a further solution, a circumferential water collecting groove is provided on the top surface of the fixed disk, and several uniformly distributed drain holes are opened on one side of the groove bottom close to the inner groove wall; a connector upper shell circumferentially located on the outer periphery of the connector is connected to the connector, and the connector upper shell movably covers above the water collecting groove along with the connector, and a water discharge gap is formed between the outer groove wall of the water collecting groove.

[0016] As a further solution, several circumferentially uniformly distributed positioning and connecting columns extend downward from the bottom surface of the fixed disk, and several positioning grooves corresponding to the number of the positioning and connecting columns extend from the top surface of the support disk. The positioning and connecting columns are inserted and matched with the positioning grooves; and at least part of the groove bottom of the positioning grooves is provided with connecting through holes corresponding to the positioning and connecting columns, and the support disk and the fixed disk are firmly connected by screwing through the connecting through holes and the positioning and connecting columns.

[0017] As a further solution, a limiting fence extending to the outer side of the second connecting column is extended at the upper end of the connecting support leg.

[0018] As a further solution, a central through hole is opened on the connector, and an automatic water inlet pipe is installed in the central through hole.

[0019] The beneficial effects of the present utility model are as follows:

[0020] A connector with a weighing function of the present utility model changes the traditional way of automatically adding water by probe induction. By replacing the induction probe with a movable inductor in the inductor, the production cost can be saved. The heating disk therein no longer needs to be perforated, ensuring the integrity of the heating disk at the bottom of the electric kettle, making it more beautiful and convenient to clean. By utilizing the expansion and contraction effect of the strain gauge in the inductor, when water is injected into the kettle, the strain gauge will generate corresponding strain, which will cause a change in its resistance value to control the water injection timing and time of the kettle, improving the automation degree of the kettle and enhancing the user experience.

[0028] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. Embodiment 1:

[0029] As Figures 1 to 6 shown, a connector with a weighing function includes a connection base 1 and a connector 2. The connector 2 is movably assembled above the connection base 1 and can move up and down relative to the connection base 1. A sensor support frame 3 is connected below the connector 2, and a movable sensor 4 for electrically connecting to a control system is connected to the sensor support frame 3. A contact support frame 5 is connected below the connection base 1, and a fixed contact point 501 is provided on the contact support frame 5 and is located below the movable sensor 4. The movable sensor 4 moves up and down with the connector 2 and presses against the fixed contact point 501. The connector 2 sinks or rises according to different bearing weights, so that the movable sensor 4 increases or decreases the force applied to the fixed contact point 501, causing the movable sensor 4 to deform and its resistance value to change.

[0030] This connector 2 changes the traditional way of automatically adding water by a probe sensor. By replacing the induction probe with the movable sensor 44, the production cost can be saved. The heating plate therein no longer needs to be perforated, ensuring the integrity of the heating plate at the bottom of the electric kettle, making it more beautiful and convenient to clean.

[0031] During use, set the no-load value of the electric kettle as a fixed value within a certain range of data A, the low water level fixed value as a certain range of data B, and the high water level fixed value as a certain range of data C. When exceeding this range of values, the movable sensor 4 will be affected by stress changes and then converted into an output signal to achieve the function of automatic water injection control.

[0032] The movable sensor 4 is a full-beam sensor, which includes a fixed connection frame 41, a load-bearing deformation frame 42 connected to the fixed connection frame 41, a load-bearing deformation part 43 connected to the load-bearing deformation frame 42, and a strain gauge 44 connected to the load-bearing deformation frame 42. The fixed connection frame 41 is assembled and connected to the sensor support frame 3, and the load-bearing deformation part 43 presses against the fixed contact point 501. Utilizing the stretching effect of the strain gauge 44 in the movable sensor 4, when water is injected into the kettle, its strain gauge 44 will generate corresponding strain, thereby causing a change in its resistance value to control the water injection timing and time of the kettle, improving the automation degree of the kettle and enhancing the user experience.

[0033] The motion sensor 4 of this structure measures by combining four resistors to form a bridge; when the water in the kettle decreases and increases, the bridge will generate a different output voltage signal, thereby reflecting the water level and weight in the kettle.

[0034] An upper threaded hole 431 is provided on the load-bearing deformation part 43, and a connection through hole 511 corresponding to the upper threaded hole 431 is provided on the fixed contact point 501. By passing a screw through the connection through hole 511 and the upper threaded hole 431, the fixed contact point 501 is firmly connected to the load-bearing deformation part 43; through the above structure, the fixed contact point 501 is kept connected to the load-bearing deformation part 43, improving the stability of the touch pressure.

[0035] The connection base 1 includes a support disk 6 and a fixed disk 7. The support disk 6 is firmly connected below the fixed disk 7, and a clamping gap 101 for clamping the mounting panel is formed at the edge between the two. The contact support frame 5 is fixedly connected below the support disk 6, and the fixed contact point 501 is arranged at the center of the support disk 6 through the contact support frame 5;

[0036] By firmly connecting the support disk 6 and the fixed disk 7, the mounting panel in the base is clamped between the clamping gaps 101, thereby fixing the entire electrical connector; and by arranging the motion sensor 4 at the center position, the force on the motion sensor 4 is uniform, and the connector 2 will not tilt due to the support of the motion sensor.

[0037] The contact support frame 5 includes several first connection columns 51 vertically extending downward from the support disk 6 and a balance beam 52 firmly connected to the bottom ends of the several first connection columns 51. The center of the balance beam 52 forms the fixed contact point 501 by upward stretching; the structure is simple and the installation is fast.

[0038] The sensor support frame 3 includes a connection bottom plate 31 placed directly below the connector 2. The motion sensor 4 is fixed on the lower side of the connection bottom plate 31. A plurality of connection support feet 32 are circumferentially and evenly distributed on the upper side of the connection bottom plate 31. The bottom surface of the connector 2 extends a plurality of second connection columns 21 corresponding to the number of the connection support feet 32, and the connection support feet 32 are firmly connected to the bottom ends of the second connection columns 21.

[0039] A plurality of upper connection holes 311 are provided on the connection bottom plate 31. Hexagonal nuts are fixedly placed in the upper connection holes 311. Lower connection holes 411 corresponding to the upper connection holes 311 are provided on the fixed connection frame 41. After the screw section of the hexagonal nut passes through the lower connection holes 411, a nut is screwed in to fix the motion sensor 4 on the lower side of the connection bottom plate 31.

[0040] The top surface of the fixed disk 7 is provided with a circumferential water collecting groove 71, and a plurality of uniformly distributed drain holes 72 are formed on one side of the groove bottom close to the inner groove wall; a connector upper shell 8 circumferentially disposed on the outer periphery of the connector 2 is connected to the connector 2. The connector upper shell 8 movably covers above the water collecting groove 71 along with the connector 2, and a water discharge gap 701 is formed between the outer groove wall of the water collecting groove 71;

[0041] The connector upper shell 8 slopes downward from the center to the edge. When water overflows from the electric kettle and drips onto the surface of the connector upper shell 8, the water flows into the water collecting groove 71 through the water discharge gap 701, and finally the water is drained through the drain holes 72, preventing the connector 2 from contacting water and causing electric leakage and short - circuit accidents;

[0042] In addition, the connector upper shell 8 is embedded in the water collecting groove 71, which can prevent foreign objects on the base from being stuck between the connector upper shell 8 and the fixed disk 7, resulting in abnormal weighing caused by the inability of the connector 2 to move up and down.

[0043] A number of circumferentially uniformly distributed positioning and connecting columns 73 extend downward from the bottom surface of the fixed disk 7, and a number of positioning grooves 61 corresponding to the number of the positioning and connecting columns 73 extend from the top surface of the support disk 6. Through the insertion and cooperation of the positioning and connecting columns 73 and the positioning grooves 61, the fixed disk 7 can be positioned and assembled above the support disk 6;

[0044] During further assembly, and at least some of the bottom surfaces of the positioning grooves 61 are provided with connecting through - holes 611 corresponding to the positioning and connecting columns 73. By screwing through the connecting through - holes 611 and the positioning and connecting columns 73, the support disk and the fixed disk are firmly connected, thereby clamping the mounting panel in the clamping gap 101.

[0045] The upper end of the connecting support leg 32 extends with a limiting fence 33 that is limited to the outer side of the second connecting column 21. When the sensor support frame 3 is assembled to the bottom surface of the connector 2, by using the cooperation of the limiting fence 33 and the second connecting column 21, each connecting support leg 32 can be quickly aligned with the second connecting column 21, preventing the sensor support frame 3 from shaking left and right after single - point fixing, resulting in misalignment of other connecting support legs 32 and the second connecting column 21, which helps to improve the assembly efficiency.

[0046] A central through - hole 201 is formed on the connector 2, and an automatic water inlet pipe 9 is installed in the central through - hole 201. This structure enables the connector 2 to have the function of water inlet or outlet at the bottom. Embodiment Two:

[0047] The difference between Embodiment Two and Embodiment One is that as Figure 7As shown, the connection base 1 is the mounting panel 10. An assembly hole 1001 for accommodating the connector 2 is formed in the mounting panel 10. A number of first connecting columns 51 are connected to the bottom surface of the mounting panel 10. The balance beam 52 is fixedly connected to the mounting panel 10 through the first connecting columns 51, and the balance beam 52 is tightly connected to the movable inductor 4 and supports the connector 2, so that the connector 2 is suspended above the mounting panel 10 and can move up and down relative to the assembly hole. The remaining structures such as the connector upper shell 8 are the same as those in the first embodiment and will not be repeated here.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
