Description

Technical Field

[0001] The utility model relates to a coupler and a cooking vessel using the coupler. Background Art

[0002] In the prior art, cooking utensils typically use a coupler to connect the pot and the base, transmitting electrical energy through a conductive structure to power the heating element in the pot. However, the coupler structure in the prior art has the following problems:

[0003] First, existing coupler designs lack safety. When the cookware is seated on the base, the conductive structure is easily exposed to the outside environment, posing a safety hazard of electric shock. Furthermore, coupler connections typically rely on mechanical interlocking or simple elastic contact structures. These structures are prone to wear with increased use, resulting in unstable or poor contact, which in turn affects the stability and reliability of power transmission.

[0004] Secondly, the existing coupler is not easy to operate when connecting the cookware to the base. In the existing technology, connecting and disconnecting the coupler requires relatively complex operation steps, and the user needs to accurately align the position when using it, which increases the difficulty of operation, is not conducive to the user's quick operation, and affects the user experience.

[0005] In addition, the coupler structure in the prior art often lacks an effective power-off protection mechanism when disconnecting the circuit, which means that the circuit may not be completely disconnected when the cookware is disassembled, further increasing the safety risks during use. Utility Model Content

[0006] The first purpose of the utility model is to provide a coupler with high safety performance and easier operation.

[0007] The second object of the present invention is to provide an electrically heated cooking vessel with higher safety performance, easier operation, and suitable for cooking vessels that require frequent connection and disconnection.

[0008] The first purpose of the utility model is achieved in this way:

[0009] A coupler includes an upper connecting base and a lower connecting base, wherein the lower connecting base includes a base, a first conductive spring, a second conductive spring, a first elastic member, and a pressing member, wherein the first conductive spring and the second conductive spring are disposed within the base, the first conductive spring is connected to a power source, and the first elastic member is disposed within the base, wherein the elastic force of the first elastic member pushes the first conductive spring away from the second conductive spring;

[0010] The pressing component is movably disposed in the base, and the pressing component controls the first conductive spring to move away from or contact the second conductive spring;

[0011] The base is provided with a socket at a position corresponding to the pressing component, and the base is provided with a power supply opening at a position corresponding to the second conductive spring;

[0012] The upper connecting seat includes a column for pushing the pressing component to move and a conductive pin for connecting to the electrical device and for contacting the second conductive elastic sheet;

[0013] When the upper connecting seat and the lower connecting seat are connected, the conductive needle enters the power supply opening and contacts the second conductive spring sheet. The column moves downward to push the pressing component, so that the pressing component drives the first conductive spring sheet to contact the second conductive spring sheet. The power supply supplies power to the electrical equipment through the first conductive spring sheet, the second conductive spring sheet and the conductive needle.

[0014] The coupler design uses the elastic force of the first elastic member to keep the first conductive spring sheet and the second conductive spring sheet separated when not connected, thereby automatically disconnecting the circuit when not engaged, avoiding the risk of electric shock caused by accidental contact with conductive parts, and greatly improving safety during use.

[0015] When the upper connecting seat and the lower connecting seat are connected, the circuit can be automatically connected through the automatic docking of the conductive needle and the conductive spring sheet, and the closing of the conductive spring sheet by the column pushing the pressing component; when the upper connecting seat and the lower connecting seat are separated, the elastic part automatically pushes the conductive spring sheet to separate, realizing automatic disconnection of the circuit, without the need for manual operation by the user, making it more convenient and quick to use.

[0016] The design of the pressing component ensures precise contact and separation between the first conductive spring and the second conductive spring during connection and disconnection, reduces the risk of poor contact, and enhances the stability and reliability of power transmission.

[0017] The coupler design uses the combination of the column and the pressing component to eliminate the need for complicated alignment and adjustment when performing coupling operations. The connection process is smooth, greatly simplifying the operation steps and improving the user experience.

[0018] This coupler design is suitable for a variety of scenarios that require frequent disconnection and connection, especially in electric heating cooking appliances. Through reliable power control and grounding protection design, it can effectively improve the safety and service life of the equipment.

[0019] The first purpose of the present invention can also be solved by the following technical measures:

[0020] Furthermore, it also includes a second elastic member, which is placed in the base. One end of the second elastic member abuts against the pressing member, and the other end of the second elastic member abuts against the inner wall of the base. The second elastic member constitutes a reset mechanism of the pressing member.

[0021] The second elastic member serves as a reset mechanism, which can automatically reset the pressing component when the upper connecting seat is separated from the lower connecting seat, thereby avoiding poor contact or leakage problems caused by the failure of the pressing component to be reset.

[0022] Furthermore, the first conductive elastic sheet is provided with a first contact, and the second conductive elastic sheet is provided with a second contact. When the first conductive elastic sheet moves, the first conductive elastic sheet drives the first contact to contact or move away from the second contact of the second conductive elastic sheet.

[0023] By setting up dedicated conductive contacts, the conductive area can be effectively increased and the contact resistance can be reduced, thereby improving the efficiency and stability of power transmission and ensuring smooth current transmission when the equipment is working.

[0024] The contact point arrangement can enhance the contact stability between the first conductive spring and the second conductive spring, avoiding circuit breakage or current instability caused by poor contact. This design ensures that the circuit can maintain good conductivity even when it is frequently opened and closed.

[0025] The special contact design can reduce the wear caused by direct contact of the conductive springs and slow down the aging of the material, thereby extending the overall service life of the coupler and improving its reliability.

[0026] The contact design makes the contact of the conductive spring more sensitive during connection operations, and the circuit can be reliably connected and disconnected even with slight operations, improving the user experience.

[0027] Furthermore, the pressing component is provided with a first inclined surface, the upper section of the first conductive spring sheet is bent to form a pressure-receiving portion, the pressure-receiving portion is provided with a second inclined surface, the second inclined surface is tightly attached to the first inclined surface, and when the pressing component moves up or down, the first inclined surface slides along the second inclined surface and pushes the first conductive spring sheet to swing through the pressure-receiving portion.

[0028] Through the inclined surface design, the up and down movement of the pressing component can more efficiently transmit force to the first conductive spring, causing it to swing precisely, achieving smooth contact and separation between the conductive sheets, and making the operation more sensitive and reliable.

[0029] The inclined sliding structure provides a more stable force path, avoiding the uneven force or friction jamming caused by direct pressure in traditional designs, and ensuring the stability and smoothness of the conductive sheet during swinging.

[0030] The inclined sliding design not only disperses the force, but also reduces the direct friction between the pressing parts and the conductive sheets, which reduces the wear of these key components under frequent use and extends the overall service life of the coupler.

[0031] The inclined surface structure makes the swinging process of the conductive sheet more controllable, and can accurately control the contact or distance position of the conductive sheet, ensuring the reliability of circuit connection and disconnection during the opening and closing process.

[0032] The inclined sliding provides a natural and smooth operating feel. Users can feel the smooth process of connection or disconnection during use, which improves the overall operating experience.

[0033] Furthermore, the first elastic member and the second elastic member are both springs.

[0034] Furthermore, the upper connecting seat also includes a conductive column for grounding, the lower connecting seat is provided with a grounding terminal, and the base has a grounding opening corresponding to the position of the grounding terminal. When the upper connecting seat and the lower connecting seat are connected, the conductive column passes through the grounding opening to connect to the grounding terminal.

[0035] An independent grounding structure effectively prevents the risk of electric shock from equipment leakage, providing enhanced user safety. This structure directs excess current to the ground, protecting users from electric shock in the event of equipment anomalies or malfunctions.

[0036] This design complies with the grounding requirements of relevant electrical equipment, enabling the product to meet safety certification standards and market access conditions in application, and has a broader application prospect.

[0037] The coordinated use of the grounding column and the grounding terminal can effectively reduce electromagnetic interference in the circuit, improve the stability of equipment operation, and ensure the normal operation of electrical appliances in complex electromagnetic environments.

[0038] The grounding column and grounding terminal are designed to be compact and occupy little space, without affecting the overall appearance and installation layout of the coupler. At the same time, the position setting of the grounding opening also facilitates the smooth insertion and connection of the conductive column.

[0039] The grounding process is completely dependent on the normal connection between the upper and lower connectors. Users can achieve the grounding function without additional operation, which improves the convenience of use and the safety of equipment operation.

[0040] The second purpose of the present invention is achieved in this way:

[0041] A cooking vessel further includes a pot and a base, wherein a heating element is provided at the bottom of the pot, a conductive pin of the upper connecting base is connected to a power supply end of the heating element, and a column of the upper connecting base and a conductive column are provided at the bottom of the pot;

[0042] The machine base is provided with a pot accommodating cavity, and the bottom of the pot accommodating cavity is provided with the lower connecting seat;

[0043] The cookware is placed in the cookware accommodating cavity, the conductive needle enters the power supply opening and contacts the second conductive spring sheet, the column moves downward to push the pressing component, so that the pressing component drives the first conductive spring sheet to contact the second conductive spring sheet, the conductive column passes through the grounding opening and connects to the grounding terminal, and the power supply supplies power to the heating element through the first conductive spring sheet, the second conductive spring sheet and the conductive needle.

[0044] When the cookware is placed in the housing, the conductive pin automatically enters the power supply opening and contacts the second conductive spring. Simultaneously, the cylinder moves downward, pushing the pressing component to complete the circuit. This entire process eliminates the need for complex user operations, simplifying the connection between the cookware and the housing and making it more convenient to use.

[0045] The separation of the first and second conductive springs automatically disconnects the circuit when not connected, preventing accidental electric shock. The circuit connects only when the cookware is properly placed, ensuring a safe power supply.

[0046] When connected, the conductive column at the bottom of the cookware passes through the grounding opening and is reliably connected to the grounding terminal of the lower connecting base, realizing independent grounding protection, effectively preventing safety problems caused by leakage, and complying with safety regulations for electrical equipment.

[0047] The contact between the conductive pin and the spring is optimized through an elastic structure and bevel design, ensuring contact stability and transmission efficiency even after long-term use. Whether it is frequent use or high power output, the device can maintain a stable power supply.

[0048] The elastic design of key structures such as pressing parts and elastic conductive sheets not only reduces wear, but also ensures the durability of the equipment and extends the service life of the coupler and the overall cooking vessel.

[0049] Moreover, the design of the utility model is applicable to various pots and pans that require electric heating, such as boiling pots, frying pans, etc., and can provide a safe, efficient and convenient cooking experience in different home and commercial environments.

[0050] The second purpose of the present invention can also be solved by the following technical measures:

[0051] Furthermore, the machine further comprises a control panel, the control panel being arranged on a side wall of the machine base, a thermostat being arranged at the bottom of the pot accommodating cavity, a temperature sensing portion of the thermostat facing the open opening of the pot accommodating cavity, and the thermostat, the heating element and the control panel being electrically connected;

[0052] The pot is placed in the pot accommodating cavity, and the temperature sensing portion of the thermostat is in close contact with the bottom wall of the pot.

[0053] The temperature-sensing part of the thermostat is in close contact with the bottom wall of the pot, and can sense the temperature changes in the pot in real time and accurately. The temperature is adjusted and displayed through the control panel to ensure temperature stability during the cooking process, thereby achieving more precise cooking results.

[0054] The control panel is linked with the thermostat to automatically adjust the heating power according to the set temperature, realizing intelligent temperature control function. Users do not need to make frequent manual adjustments, and the user experience is more convenient and intelligent.

[0055] The real-time monitoring function of the thermostat can effectively prevent the temperature of the pot from being too high. Once the temperature exceeds the safe range, the system can automatically reduce the power or cut off the power to provide overheating protection and prevent safety hazards caused by abnormal temperature.

[0056] Through the control panel, users can select corresponding modes according to different cooking needs, such as boiling, frying, stewing, etc., further improving the diversity and convenience of cooking.

[0057] The temperature-sensing part of the thermostat is close to the bottom of the pot, and can quickly detect temperature changes and feed back to the control panel. The system can respond in a short time to ensure instant temperature adjustment during the cooking process and avoid the impact of temperature fluctuations on the cooking effect.

[0058] Through the combined design of the control panel and thermostat, the device becomes more intelligent in heating and temperature control, and the user experience becomes more humane, which is in line with the development trend of smart home appliances.

[0059] The beneficial effects of the utility model are as follows:

[0060] In the present utility model, the coupler design uses the elastic force of the first elastic member to keep the first conductive spring sheet and the second conductive spring sheet separated when not connected, thereby automatically disconnecting the circuit when not engaged, avoiding the risk of electric shock caused by accidental contact with the conductive parts, and greatly improving safety during use.

[0061] The utility model can automatically complete the connection of the circuit by automatically docking the conductive needle with the conductive spring sheet when the upper connecting seat and the lower connecting seat are connected, and the column pushes the pressing component to close the conductive spring sheet; when the upper connecting seat and the lower connecting seat are separated, the elastic member automatically pushes the conductive spring sheet to separate, thereby automatically disconnecting the circuit without the need for manual operation by the user, making it more convenient and quick to use.

[0062] In the present invention, the design of the pressing component ensures the precise contact and separation of the first conductive spring sheet and the second conductive spring sheet during the connection and disconnection process, reduces the risk of poor contact, and enhances the stability and reliability of power transmission.

[0063] The utility model adopts a coupler design that cooperates with the column and the pressing component, so that the user does not need complicated alignment and adjustment when performing the coupling operation. The connection process is smooth, which greatly simplifies the operation steps and improves the user experience.

[0064] In the present invention, through the inclined surface design, the up and down movement of the pressing component can more efficiently transmit force to the first conductive spring sheet, causing it to swing accurately, thereby achieving smooth contact and separation between the conductive sheets, and making the operation more sensitive and reliable.

[0065] When the cookware is placed in the housing, the conductive pin automatically enters the power supply opening and contacts the second conductive spring. Simultaneously, the column moves downward, pushing the pressing component to complete the circuit. This entire process eliminates the need for complex user operations, simplifies the connection between the cookware and the housing, and makes it more convenient to use.

[0066] The utility model uses a separate design of the first conductive spring and the second conductive spring, which automatically disconnects the circuit when not connected, preventing accidental electric shock. The circuit is only connected when the pot is correctly placed, ensuring the safety of the power supply process.

[0067] The utility model realizes accurate control of the temperature of the pot by combining the thermostat and the control panel in the design of the cooking utensil, thus avoiding the problem of overheating and ensuring the cooking effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0080] Example, combined with Figures 1 to 11 As shown, a coupler includes an upper connecting base 1 and a lower connecting base 2. The lower connecting base 2 includes a base 3, a first conductive spring 4, a second conductive spring 5, a first elastic member 6, and a pressing component 7. The first conductive spring 4 and the second conductive spring 5 are placed in the base 3. The first conductive spring 4 is connected to a power source. The first elastic member 6 is placed in the base 3. The elastic force of the first elastic member 6 pushes the first conductive spring 4 away from the second conductive spring 5.

[0081] The pressing component 7 is movably disposed in the base 3 , and the pressing component 7 controls the first conductive spring 4 to move away from or contact the second conductive spring 5 ;

[0082] The base 3 has a socket 31 at a position corresponding to the pressing component 7, and the base 3 has a power supply opening 32 at a position corresponding to the second conductive spring 5;

[0083] The upper connecting seat 1 includes a column 11 for pushing the pressing component 7 to move and a conductive pin 12 for connecting to an electrical device and for contacting the second conductive elastic sheet 5;

[0084] When the upper connecting seat 1 and the lower connecting seat 2 are connected, the conductive needle 12 enters the power supply opening 32 and contacts the second conductive spring piece 5. The column 11 moves downward to push the pressing component 7, so that the pressing component 7 drives the first conductive spring piece 4 to contact the second conductive spring piece 5. The power supply is supplied to the electrical equipment through the first conductive spring piece 4, the second conductive spring piece 5 and the conductive needle 12.

[0085] Furthermore, it also includes a second elastic member 8, which is placed in the base 3, with one end of the second elastic member 8 resting on the pressing member 7 and the other end of the second elastic member 8 resting on the inner wall of the base 3. The second elastic member 8 constitutes a reset mechanism of the pressing member 7.

[0086] Furthermore, the first conductive elastic sheet 4 is provided with a first contact 41 , and the second conductive elastic sheet is provided with a second contact 42 . When the first conductive elastic sheet 4 moves, the first conductive elastic sheet 4 drives the first contact 41 to contact or move away from the second contact 42 of the second conductive elastic sheet.

[0087] Furthermore, the pressing component 7 is provided with a first inclined surface 71, the upper section of the first conductive spring sheet 4 is bent to form a pressure-receiving portion 421, and the pressure-receiving portion 421 is provided with a second inclined surface 43, and the second inclined surface 43 is close to the first inclined surface 71. When the pressing component 7 moves up or down, the first inclined surface 71 slides along the second inclined surface 43 and pushes the first conductive spring sheet 4 to swing through the pressure-receiving portion 421.

[0088] Furthermore, the first elastic member 6 and the second elastic member 8 are both springs.

[0089] Furthermore, the upper connecting seat 1 also includes a conductive column 13 for grounding, the lower connecting seat 2 is provided with a grounding terminal, and the base 3 has a grounding opening 33 corresponding to the position of the grounding terminal. When the upper connecting seat 1 and the lower connecting seat 2 are connected, the conductive column 13 passes through the grounding opening 33 to connect to the grounding terminal.

[0090] Working principle of coupler:

[0091] When the upper connecting seat 1 and the lower connecting seat 2 are connected:

[0092] The pillar 11 and the conductive pin 12 in the upper connector 1 work together, and the specific process is as follows:

[0093] The column 11 pushes the pressing component 7 : the column 11 in the upper connecting seat 1 moves downward, enters the socket 31 of the lower connecting seat 2 , and pushes the pressing component 7 in the lower connecting seat 2 .

[0094] The pressing member 7 drives the conductive springs to contact: as the pressing member 7 moves, the originally separated first conductive spring 4 moves downward under the action of the pressing member 7 and contacts the second conductive spring 5. At this time, the first elastic member 6 is compressed.

[0095] The conductive needle 12 contacts the second conductive spring 5 : the conductive needle 12 in the upper connecting base 1 simultaneously enters the power supply opening 32 of the lower connecting base 2 and directly contacts the second conductive spring 5 to form a conductive path.

[0096] Power supply: Power is transmitted to the electrical equipment connected to the upper connecting base 1 through the first conductive spring piece 4, the second conductive spring piece 5 and the conductive needle 12 to complete the power supply.

[0097] Grounding protection: During the connection process, the conductive column 13 passes through the grounding opening 33 and connects to the grounding terminal in the lower connection base 2, providing grounding protection and enhancing equipment safety.

[0098] When the upper connecting seat 1 and the lower connecting seat 2 are separated:

[0099] The column 11 rebounds: as the upper connecting seat 1 is removed, the column 11 withdraws from the socket 31, and the pressing component 7 automatically resets under the action of the second elastic member 8 (such as a spring).

[0100] The conductive spring is disconnected: after the pressing component 7 is reset, the first conductive spring 4 rebounds under the action of the first elastic member 6 and breaks away from the contact with the second conductive spring 5, the circuit is disconnected, and the power supply is stopped.

[0101] The conductive needle 12 and the conductive spring are separated: the conductive needle 12 withdraws from the power supply opening 32 and breaks contact with the second conductive spring 5 .

[0102] Safe power off: The coupler returns to the power off state, ensuring the safety of the equipment in the non-working state.

[0103] Example, combined with Figures 1 to 11 As shown, a cooking vessel also includes a pot 9 and a base 10, a heating element 91 is provided at the bottom of the pot 9, a conductive pin 12 of the upper connecting base 1 is connected to the power supply end of the heating element 91, and a column 11 and a conductive column 13 of the upper connecting base 1 are provided at the bottom of the pot 9;

[0104] The base 10 is provided with a pot accommodating cavity 101, and the bottom of the pot accommodating cavity 101 is provided with the lower connecting seat 2;

[0105] The pot 9 is placed in the pot accommodating cavity 101, the conductive needle 12 enters the power supply opening 32 and contacts the second conductive spring 5, the column 11 moves downward to push the pressing component 7, so that the pressing component 7 drives the first conductive spring 4 to contact the second conductive spring 5, and the conductive column 13 passes through the grounding opening 33 to connect to the grounding terminal. The power supply supplies power to the heating element 91 through the first conductive spring 4, the second conductive spring 5 and the conductive needle 12.

[0106] Furthermore, the machine further includes a control panel 200, which is disposed on a side wall of the base 10. A thermostat 300 is disposed at the bottom of the pot accommodating cavity 101, with a temperature sensing portion of the thermostat 300 facing the open opening of the pot accommodating cavity 101. The thermostat 300, the heating element 91, and the control panel 200 are electrically connected.

[0107] The pot 9 is placed in the pot accommodating cavity 101 , and the temperature sensing portion of the thermostat 300 is in close contact with the bottom wall of the pot 9 .

[0108] Working principle of the connection and separation of the pot 9 and the base 10:

[0109] When the pot 9 and the base 10 are connected:

[0110] When the pot 9 is placed in the receiving cavity of the base 10, the connection process is as follows:

[0111] Automatic docking: The upper connecting seat 1 at the bottom of the pot 9 automatically docks with the lower connecting seat 2 at the bottom of the machine base 10. At this time, the weight of the pot 9 causes the column 11 to move downward, pushing the pressing component 7.

[0112] The conductive needle 12 contacts the conductive spring: the conductive needle 12 at the bottom of the cookware 9 enters the power supply opening 32 of the lower connecting seat 2 and contacts the second conductive spring 5 to form a conductive loop.

[0113] The pressing component 7 drives: the column 11 moves downward to push the pressing component 7, driving the first conductive spring 4 to contact the second conductive spring 5, and the power supply is supplied to the heating element 91 at the bottom of the pot 9 through the coupler.

[0114] Grounding protection is achieved: the conductive column 13 at the bottom of the pot 9 passes through the grounding opening 33 and is connected to the grounding terminal of the lower connecting base 2 to form grounding protection and ensure safe use.

[0115] The thermostat 300 monitors the temperature: The temperature sensing portion of the thermostat 300 is in close contact with the bottom wall of the cookware 9, monitors the temperature in real time, and adjusts and controls the working state of the heating element 91 through the control panel 200 to ensure accurate temperature control.

[0116] When the pot 9 and the base 10 are separated:

[0117] The column 11 rebounds: the column 11 and the conductive needle 12 automatically withdraw from the lower connecting seat 2, the pressing component 7 is reset under the action of the second elastic member 8, the first conductive spring 4 is separated from the second conductive spring 5 under the action of the first elastic member 6, and the circuit is disconnected.

[0118] The conductive path is cut off: the conductive needle 12 is separated from the second conductive spring 5, the power supply stops, the heating element 91 is powered off, and cooking is finished.

[0119] Grounding disconnection: The conductive column 13 is separated from the grounding terminal, disconnecting the grounding path.

[0120] Thermostat 300 recovers: The temperature sensing portion of the thermostat 300 separates from the bottom wall of the cookware 9 and stops monitoring the temperature.

[0121] Through the above design, whether it is the connection and disconnection of the coupler or the connection and disconnection of the cookware 9 and the base 10, safe, reliable and convenient circuit control and grounding protection are achieved, ensuring the efficiency and safety of the equipment during use.
