Description

Technical Field

[0001] The embodiments of the present invention relate to the field of household appliance technology, and more specifically, to a liquid measuring device and a cooking utensil. Background Technology

[0002] Currently, automatic cooking machines require a fixed amount of water to be added when cooking food. However, the current technology typically uses flow meters and volume meters to measure the amount of water added, which results in a complex structure and high cost for the automatic cooking machine. Summary of the Invention

[0003] The embodiments of the present invention are intended to at least solve one of the technical problems existing in the prior art.

[0004] Therefore, a first aspect of the embodiments of the present invention provides a liquid measuring device.

[0005] A second aspect of the present invention provides a cooking utensil.

[0006] In view of the above, according to a first aspect of the present invention, a liquid measuring device is provided, the liquid measuring device comprising: a housing having a receiving cavity; an inlet and an outlet disposed on the housing, the inlet and outlet respectively communicating with the receiving cavity; and a switching assembly movable relative to the housing between a first position and a second position; wherein, based on the switching assembly being in the first position, the switching assembly opens the inlet and closes the outlet; and based on the switching assembly being in the second position, the switching assembly closes the inlet and opens the outlet.

[0007] The liquid measuring device provided in this embodiment of the invention includes a housing, a liquid inlet, a liquid outlet, and a switching assembly. Specifically, the housing is provided with a receiving cavity, which is capable of containing liquid. The housing is also provided with a liquid inlet, which communicates with the receiving cavity, meaning that liquid enters the receiving cavity through the liquid inlet. The housing is also provided with a liquid outlet, which communicates with the receiving cavity, meaning that after the receiving cavity is filled with liquid, it is discharged from the receiving cavity through the liquid outlet.

[0008] The switching assembly is movable relative to the housing and controls the opening and closing of the inlet and outlet during its movement, thereby achieving quantitative liquid delivery. Specifically, the switching assembly can move between a first position and a second position. When the switching assembly is in the first position, it opens the inlet and closes the outlet, allowing liquid to enter the receiving cavity from the inlet. When the receiving cavity is full of liquid, the switching assembly moves from the first position to the second position. At this time, it opens the outlet and closes the inlet, allowing liquid in the receiving cavity to flow out from the outlet, thus achieving quantitative liquid delivery.

[0009] It's understandable that the volume of the receiving cavity is fixed. When the liquid fills the measuring cavity, the volume of the liquid is deterministic. Therefore, the total volume of liquid delivered can be calculated based on the number of times liquid is poured into the receiving cavity, thus achieving precise control over the delivered liquid volume. When delivering cooking water, this effectively prevents the problem of reduced rice texture due to excessive water volume delivered to the cooking pot. Furthermore, it effectively prevents the problem of undercooked rice due to insufficient water volume delivered to the cooking pot, thereby improving the user experience of the cooking appliance.

[0010] Furthermore, by controlling the opening and closing of the inlet and outlet during movement using a switching assembly, a quantitative liquid delivery can be achieved. This eliminates the need for components such as flow meters used in related technologies to measure liquid volume, simplifying the structure of the liquid measuring device and reducing the production cost of the liquid measuring device and cooking appliances equipped with it.

[0011] In practical applications, the liquid inlet is located above the receiving cavity, the liquid outlet is located below the receiving cavity, and the liquid storage tank is located above the liquid inlet. Thus, when the liquid inlet is opened, the liquid enters the receiving cavity through the liquid inlet due to gravity, eliminating the need for components such as water pumps in related technologies to pump the liquid. This further simplifies the structure of the liquid measuring device and reduces the production cost of the liquid measuring device and the cooking utensils with the liquid measuring device.

[0012] The pot body of the cooking appliance is located below the outer shell. When the liquid outlet is opened, the liquid in the receiving cavity flows out from the outlet into the pot body due to gravity, thus achieving a metered liquid delivery. Furthermore, it eliminates the need for components such as water pumps used in related technologies to pump the liquid, further simplifying the structure of the liquid measuring device and reducing the production cost of the liquid measuring device and the cooking appliance incorporating it.

[0013] It should be noted that when this measuring device is applied to cooking utensils, the volume of the receiving cavity is the minimum amount of water that needs to be added during cooking. In other words, the volume delivered by the measuring device at one time is the minimum amount of water required for cooking, thus preventing the problem of excessive water intake due to an overly large receiving cavity, which could affect the taste of the cooked food.

[0014] In addition, the liquid measuring device provided by the above-described technical solution of the present invention also has the following additional technical features:

[0015] In one possible technical solution, the switching assembly includes a first switching element, a second switching element, and a movable element. The first switching element is located at the liquid inlet, the second switching element is located at the liquid outlet, and at least a portion of the movable element is located within the receiving cavity and is movable relative to the housing between a first position and a second position. When the movable element is in the first position, the first switching element opens the liquid inlet, and the second switching element closes the liquid outlet; when the movable element is in the second position, the first switching element closes the liquid inlet, and the second switching element opens the liquid outlet.

[0016] In this technical solution, the switching assembly includes a first switching element, a second switching element, and a movable element. Specifically, the first switching element is located at the liquid inlet, meaning it can open or close the liquid inlet. The second switching element is located at the liquid outlet, meaning it can open or close the liquid outlet. Furthermore, the movable element can move relative to the housing, and during its movement, it can drive the first and second switching elements to move, thereby enabling the first and second switching elements to control the opening and closing states of the liquid inlet and outlet, achieving the delivery of a fixed quantity of liquid.

[0017] Specifically, when the movable part is in the first position, the first switch opens the liquid inlet and the second switch closes the liquid outlet, allowing liquid to enter the receiving cavity from the liquid inlet. When the receiving cavity is full, the movable part moves from the first position to the second position, the first switch closes the liquid inlet, and the second switch opens the liquid outlet, allowing the liquid in the receiving cavity to flow out from the liquid outlet, thus achieving quantitative liquid delivery. The total volume of liquid delivered is calculated based on the number of times liquid is delivered to the receiving cavity, thereby achieving precise control of the delivered liquid volume. When delivering cooking water, this effectively prevents the problem of reduced rice texture due to excessive water volume delivered to the cooking pot. Furthermore, it effectively prevents the problem of undercooked rice due to insufficient water volume delivered to the cooking pot, improving the user experience of the cooking appliance.

[0018] Furthermore, by controlling the opening and closing of the inlet and outlet during movement using a switching assembly, a quantitative liquid delivery can be achieved. This eliminates the need for components such as flow meters used in related technologies to measure liquid volume, simplifying the structure of the liquid measuring device and reducing the production cost of the liquid measuring device and cooking appliances equipped with it.

[0019] In practical applications, the first switching element is a first check valve, and the second switching element is a second check valve. The movable element is located within the receiving cavity, and a portion of both the first and second check valves is also located within the receiving cavity. During the movement of the movable element, it pushes both the first and second check valves to move away from the receiving cavity. Specifically, when the movable element contacts the first check valve, it can push the check valve to move, causing the first check valve to open the inlet. When the movable element disengages from the first check valve, the first check valve resets and closes the inlet. Similarly, when the movable element contacts the second check valve, it can push the check valve to move, causing the second check valve to open the outlet. When the movable element disengages from the second check valve, the second check valve resets and closes the outlet.

[0020] In detail, when the movable part is in the first position, it abuts against the first one-way valve, but not against the second one-way valve. The first one-way valve opens the inlet, and the second one-way valve closes the outlet. Liquid enters the receiving chamber through the inlet. When the receiving chamber is full of liquid, the movable part moves from the first position to the second position, disengaging from the first one-way valve. The first one-way valve closes the inlet, and simultaneously, the movable part abuts against the second one-way valve, opening the outlet. This achieves the delivery of a fixed quantity of liquid.

[0021] Additionally, a first magnet may be provided on the side of the first switching element facing the receiving cavity, and a second magnet may be provided on the side of the second switching element facing the receiving cavity. A first magnetically conductive part is provided on the side of the movable element facing the first switching element, and a second magnetically conductive part is provided on the side of the movable element facing the second switching element. The first magnet and the first magnetically conductive part are magnetically repelled, and the second magnet and the second magnetically conductive part are magnetically repelled. Specifically, when the movable element is in the first position, the first magnetically conductive part on the movable element and the first magnet on the first switching element are magnetically repelled, thereby pushing the first switching element to move away from the receiving cavity to open the liquid inlet. Simultaneously, the second magnet on the second switching element and the second magnetically conductive part on the movable element do not contact each other, and the liquid outlet is closed.

[0022] When the receiving cavity is filled with liquid, the movable component moves from the first position to the second position. The second magnetic conductive part on the movable component repels the second magnet on the second switching component, thereby pushing the second switching component to move away from the receiving cavity to open the liquid outlet. At the same time, the first magnet on the first switching component does not contact the first magnetic conductive part on the movable component, and the liquid inlet closes. This achieves the delivery of a fixed amount of liquid.

[0023] The specific structure of the switching and moving parts can be set according to actual needs.

[0024] In one possible technical solution, the first switching element is a first check valve, and the second switching element is a second check valve; wherein, when the movable element is in the first position, the movable element abuts against the first check valve, the first check valve opens the inlet, and when the movable element disengages from the second check valve, the second check valve closes the outlet; when the movable element is in the second position, the movable element abuts against the second check valve, the second check valve opens the outlet, and when the movable element disengages from the first check valve, the first check valve closes the inlet.

[0025] In this technical solution, the first switching element is defined as a first check valve, and the second switching element is defined as a second check valve. A movable element is located within a receiving cavity, and portions of both the first and second check valves are located within the receiving cavity. During the movement of the movable element, it pushes both the first and second check valves to move away from the receiving cavity. Specifically, when the movable element contacts the first check valve, it can push the check valve to move, causing the first check valve to open the inlet. When the movable element disengages from the first check valve, the first check valve resets and closes the inlet. Similarly, when the movable element contacts the second check valve, it can push the check valve to move, causing the second check valve to open the outlet. When the movable element disengages from the second check valve, the second check valve resets and closes the outlet.

[0026] In detail, when the movable part is in the first position, it abuts against the first one-way valve, while simultaneously not abutting against the second one-way valve. The first one-way valve opens the inlet, and the second one-way valve closes the outlet. Liquid enters the receiving cavity through the inlet. When the receiving cavity is full of liquid, the movable part moves from the first position to the second position, disengaging from the first one-way valve. The first one-way valve closes the inlet, and simultaneously abuts against the second one-way valve, opening the outlet. This achieves quantitative liquid delivery. The total volume of liquid delivered is calculated based on the number of times liquid is delivered to the receiving cavity, thus achieving precise control of the delivered liquid volume. When delivering cooking water, this effectively prevents the problem of reduced rice texture due to excessive water volume delivered to the cooking pot. Furthermore, it effectively prevents the problem of undercooked rice due to insufficient water volume delivered to the cooking pot, improving the user experience of the cooking appliance.

[0027] Furthermore, the elimination of the need for components such as flow meters in related technologies to measure liquid volume simplifies the structure of the liquid measuring device and reduces the production cost of the liquid measuring device and cooking appliances equipped with it.

[0028] In one possible technical solution, the liquid measuring device further includes a driving element connected to a movable element, which is capable of driving the movable element to move between a first position and a second position.

[0029] In this technical solution, the liquid measuring device is further defined as including a driving component. Specifically, the driving component is connected to the movable component, so that the movable component can move relative to the housing under the drive of the driving component, thereby enabling the first and second switching components to control the opening and closing states of the liquid inlet and the liquid outlet, and realizing the delivery of a quantitative liquid.

[0030] Driven by the driving component, the movable component can move between a first position and a second position. Specifically, when the movable component is in the first position, the first switch opens the inlet and the second switch closes the outlet, allowing liquid to enter the receiving cavity from the inlet. When the receiving cavity is full, the movable component moves from the first position to the second position, the first switch closes the inlet, and the second switch opens the outlet, allowing liquid in the receiving cavity to flow out from the outlet, thus achieving a quantitative liquid delivery. The total volume of liquid delivered is calculated based on the number of times liquid is delivered to the receiving cavity, thereby achieving precise control of the delivered liquid volume. When delivering cooking water, this effectively prevents the problem of reduced rice texture due to excessive water volume delivered to the cooking pot. Furthermore, it effectively prevents the problem of undercooked rice due to insufficient water volume delivered to the cooking pot, improving the user experience of the cooking appliance.

[0031] Furthermore, by controlling the opening and closing of the inlet and outlet during movement using a switching assembly, a quantitative liquid delivery can be achieved. This eliminates the need for components such as flow meters used in related technologies to measure liquid volume, simplifying the structure of the liquid measuring device and reducing the production cost of the liquid measuring device and cooking appliances equipped with it.

[0032] In practical applications, the first driving component is a motor, which is located outside the housing. Specifically, the housing has a transmission hole, through which the movable component is connected to the motor, so that the movable component can move between a first position and a second position under the drive of the motor.

[0033] In addition, the liquid measuring device may include a transmission gear set, and the moving parts are connected to the motor through the transmission gear set, thereby enabling precise control of the movement position of the moving parts, and thus improving the stability and reliability of quantitative liquid delivery.

[0034] In one possible technical solution, the liquid measuring device further includes a detection device, which is located in the housing and connected to the drive component. The detection device can detect the movement position of the moving component and control the working state of the drive component based on the movement position of the moving component.

[0035] In this technical solution, the liquid measuring device is further defined as including a detection device. Specifically, the detection device is installed on the housing and is connected to the driving component. The working state of the driving component is controlled by detecting the position of the moving part, so as to realize the quantitative liquid delivery and facilitate the control of the moving position of the moving part. The structure is simple and the operation is convenient.

[0036] Specifically, when the detection device detects that the movable part has moved to the first position, it controls the drive to stop driving the movable part, thus stopping the movable part in the first position. This causes the first switch to open the inlet and the second switch to close the outlet, allowing liquid to enter the receiving cavity through the inlet. When the receiving cavity is full of liquid, the drive continues to drive the movable part. When the detection device detects that the movable part has moved to the second position, it controls the drive to stop driving, thus stopping the movable part in the second position. This causes the first switch to close the inlet and the second switch to open the outlet. Thus, by controlling the position of the movable part detected by the detection device, the operating state of the drive is controlled, achieving quantitative liquid delivery while facilitating the control of the movable part's movement. The structure is simple and the operation is convenient.

[0037] In one possible technical solution, the detection device includes a control module, a third switch, and a fourth switch. The control module is connected to a drive unit, and the third and fourth switches are mounted on the housing. When the movable part is in a first position, a portion of the movable part triggers the third switch, causing the drive unit to stop operating. When the movable part is in a second position, a portion of the movable part triggers the fourth switch, causing the drive unit to stop operating.

[0038] In this technical solution, the detection device includes a control module, a third switch, and a fourth switch. Specifically, the drive component is connected to the control module, and the third and fourth switches are mounted on the housing. Specifically, when the movable component moves to the first position, a portion of the movable component triggers the third switch, which sends a signal to the control module. The control module then controls the drive component to stop driving. This causes the movable component to stop at the first position, thereby causing the first switch to open the liquid inlet and the second switch to close the liquid outlet, allowing liquid to enter the receiving cavity through the liquid inlet.

[0039] When the receiving cavity is filled with liquid, the driving component drives the movable component to continue moving. When the movable component moves to the second position, a portion of it triggers a fourth switch. The fourth switch sends a signal to the control module, which then stops the driving component, causing the movable component to stop at the second position. This, in turn, causes the first switch to close the inlet and the second switch to open the outlet. Thus, by detecting the position of the movable component, the operating state of the driving component is controlled, achieving quantitative liquid delivery while facilitating the control of the movable component's movement. The structure is simple and the operation is convenient.

[0040] Specifically, the third and fourth switching elements can be microswitches, springs, or other structures capable of performing the above functions.

[0041] In one possible technical solution, the movable component includes a movable part and a trigger part. The movable part is located inside the receiving cavity, and the trigger part is connected to the movable part and located outside the receiving cavity. The movement of the movable part can drive the movement of the trigger part. Specifically, when the movable component is in a first position, the trigger part triggers a third switch, and the driving component stops working. When the movable component is in a second position, the trigger part triggers a fourth switch, and the driving component stops working.

[0042] In this technical solution, the movable component includes a movable part and a trigger part. Specifically, the movable part is connected to the trigger part, and under the drive of the driving component, the movable part can drive the trigger part to move. Specifically, when the movable component moves to the first position, the trigger part can trigger the third switch, which sends a signal to the control module. The control module controls the driving component to stop driving. This causes the movable component to stop at the first position, thereby causing the first switch to open the liquid inlet and the second switch to close the liquid outlet, allowing liquid to enter the receiving cavity through the liquid inlet.

[0043] When the receiving cavity is filled with liquid, the driving component drives the movable component to continue moving. When the movable component moves to the second position, the triggering unit activates the fourth switch. The fourth switch sends a signal to the control module, which then controls the driving component to stop, causing the movable component to stop at the second position. This, in turn, causes the first switch to close the inlet and the second switch to open the outlet. Thus, by detecting the position of the movable component, the operating state of the driving component is controlled, achieving quantitative liquid delivery while facilitating the control of the movable component's movement. The structure is simple and the operation is convenient.

[0044] It should be noted that the movable part is located inside the receiving cavity, while the trigger part is located outside the receiving cavity. This means that the housing has a mounting hole through which the movable part and the trigger part connect. The measuring device also includes sealing silicone, which seals the mounting hole to prevent liquid leakage from the receiving cavity.

[0045] In one possible technical solution, the movable part is provided with a connecting cavity, and at least part of the driving member extends into the connecting cavity. The driving member is capable of driving the movable part to rotate around the axis of the connecting cavity.

[0046] In this technical solution, the structure of the movable part is further defined. The movable part has a connecting cavity located on the side of the movable part facing the driving member. The driving member has a driving shaft that can extend into the connecting cavity, thereby connecting the driving shaft to the movable part through the connecting cavity. The driving shaft can drive the movable part to rotate. As the driving shaft rotates, it can cause the movable part to rotate around the axis of the connecting cavity, which in turn causes the movable part to move the trigger part, thereby realizing the movement of the movable member between a first position and a second position.

[0047] In one possible technical solution, the movable part is further provided with a positioning protrusion, which is located at the end of the movable part away from the connecting cavity. The housing is provided with a positioning groove that matches the positioning protrusion, and at least part of the positioning protrusion extends into the positioning groove.

[0048] In this technical solution, to ensure the stability of the movable part during rotation, a positioning protrusion is also included in the movable part for positioning. Specifically, the positioning protrusion is located at the end of the movable part away from the connecting cavity, and a positioning groove adapted to the positioning protrusion is provided on the housing. At least a portion of the positioning protrusion extends into the positioning groove, thereby enabling the positioning of the movable part through the cooperation of the positioning protrusion and the positioning groove, preventing instability of the movable part during rotation. In one possible design, the detection device includes:

[0049] The control module is connected to the drive component. When the moving component is in the first or second position, the control module can control the drive component to stop for a preset time.

[0050] In this technical solution, the detection device includes a control module connected to a driving component. The control module can control the stopping duration of the driving component. Specifically, when the movable component is in the first or second position, it can open or close the inlet or outlet. Therefore, while keeping the flow rates at the inlet and outlet constant, the inflow rate at the inlet and the outflow rate at the outlet can be controlled by controlling the stopping duration of the movable component in the first or second position.

[0051] In one possible technical solution, the measuring device also includes a vent, which is located in the housing and communicates with the receiving cavity.

[0052] In this technical solution, the measuring device also includes a vent. Specifically, the vent is located on the housing, with one end connected to the receiving cavity and the other end connected to the outside. By providing the vent, the air pressure inside the receiving cavity can be kept balanced with the outside, thereby ensuring that liquid can enter the receiving cavity from the inlet. This prevents the receiving cavity from failing to fill due to trapped air, thus improving the reliability of quantitative liquid delivery.

[0053] In practical applications, the vent is located at the top of the housing to ensure that the liquid can fill the containment cavity and achieve quantitative liquid delivery.

[0054] It should be noted that the number of vents can be set as needed.

[0055] In one possible technical solution, the liquid measuring device further includes an venting component and a float. The venting component is connected to the housing and has a mounting cavity inside. The first end of the mounting cavity is connected to the vent hole, and the second end of the mounting cavity is connected to the outside. The float is located inside the mounting cavity and can float with the liquid surface to open or seal the second end of the mounting cavity.

[0056] In this technical solution, the liquid measuring device is further defined as including an venting component and a float. Specifically, the venting component is mounted on the housing, and a mounting cavity is provided inside the venting component. Specifically, one end of the mounting cavity is connected to the vent hole, and the vent hole is connected to the receiving cavity. That is, one end of the mounting cavity is connected to the receiving cavity through the vent hole. The other end of the mounting cavity can be connected to the outside, thereby ensuring that liquid can enter the receiving cavity from the inlet, preventing the receiving cavity from not being filled due to trapped air, and improving the reliability of quantitative liquid delivery.

[0057] Furthermore, the float is located inside the mounting cavity and can float with the liquid surface. Specifically, when the receiving cavity is filled with liquid, the liquid flows out from the vent hole into the mounting cavity. After the float floats to a preset position with the liquid surface, it seals the end of the mounting cavity that is connected to the outside. That is, the float seals the mounting cavity, so that the liquid no longer enters the receiving cavity. This achieves quantitative liquid delivery while sealing the receiving cavity and preventing liquid leakage from the vent hole and the mounting cavity.

[0058] When the liquid in the receiving cavity is discharged from the outlet, the liquid in the receiving cavity gradually decreases. Some of the liquid in the mounting cavity flows back into the receiving cavity. The float opens the mounting cavity, so that the air pressure in the receiving cavity is balanced with the outside, ensuring that the liquid flows out smoothly from the outlet and improving the stability and reliability of quantitative liquid delivery.

[0059] It should be noted that the second end of the mounting cavity is provided with a mounting port that communicates with the outside. The width of the float is greater than the width of the mounting port, so that when the float floats to the position of the mounting port with the liquid surface, the float can be stuck at the position of the mounting port, thereby achieving the sealing of the mounting cavity and the receiving cavity.

[0060] In one possible technical solution, the float is a buoyancy ball; the venting component is provided with an venting channel, which is connected to the second end of the mounting cavity, and the width of the venting channel is smaller than the diameter of the buoyancy ball.

[0061] In this technical solution, the float is specified as a buoyancy ball. It is understood that the buoyancy ball has a symmetrical structure, and when it floats on the liquid surface, it easily mates with the connection between the exhaust channel and the second end of the mounting cavity. This ensures the flow of gas inside and outside the cavity while simultaneously sealing the mounting cavity and the receiving cavity. This further prevents liquid leakage and improves the stability and reliability of quantitative liquid delivery.

[0062] Furthermore, the venting component is equipped with an venting channel, which connects to the second end of the mounting cavity. In other words, the second end of the mounting cavity is connected to the outside via the venting channel. The width of the venting channel is smaller than the diameter of the buoyancy ball, so that when the buoyancy ball floats to the connection point between the venting channel and the second end of the mounting cavity, the float can be engaged at this connection, ensuring gas flow between the inside and outside of the cavity while simultaneously sealing the mounting cavity and the receiving cavity. This further prevents liquid leakage and improves the stability and reliability of quantitative liquid delivery.

[0063] In one possible technical solution, the measuring device further includes a first pipeline, which is connected to the end of the venting component away from the vent hole and is connected to the venting passage.

[0064] In this technical solution, the liquid measuring device is further defined as including a first pipeline. Specifically, the first pipeline is connected to the end of the venting component away from the vent hole, and the first pipeline is connected to the venting channel. Thus, when the liquid fills the receiving cavity and the second end of the float sealing installation cavity is filled, the first pipeline can receive the liquid that seeps out between the float and the venting component, thereby preventing the seeping liquid from flowing to other parts of the cooking appliance and reducing the user experience.

[0065] In practical applications, one end of the first pipe is connected to the exhaust channel, and the other end is connected to the rice-washing water drain channel of the cooking appliance, allowing any leaked liquid to drain out along with the rice-washing water. This further prevents leaked liquid from flowing to other parts of the cooking appliance and thus reducing the user experience.

[0066] In one possible technical solution, the float includes a pressing part; the liquid measuring device also includes a fifth switching element, which is located in the mounting cavity. When the float floats with the liquid surface to a preset position, the pressing part can trigger the fifth switching element to make the first switching element close the liquid inlet.

[0067] In this technical solution, the liquid measuring device also includes a fifth switching element. Specifically, the fifth switching element is disposed within the mounting cavity. When the float floats to a preset position with the liquid level, the contact part on the float can trigger the fifth switching element, thereby closing the liquid inlet and stopping liquid from entering the receiving cavity. This prevents leakage from the vent hole after the receiving cavity is full. Furthermore, when the receiving cavity is full, the contact part can trigger the fifth switching element, enabling detection of whether the receiving cavity is full, achieving precise control of quantitative liquid intake, and improving the user experience.

[0068] Specifically, the fifth switch can be connected to the control module. When the pressure point triggers the fifth switch, it transmits a signal to the control module. The control module then controls the drive unit to operate, which in turn moves the movable part from the first position to the second position. The first switch then closes the liquid inlet, preventing further liquid from entering the container and thus preventing leakage from the vent after the container is full. Furthermore, when the container is full, the pressure point can trigger the fifth switch to detect whether the container is full, enabling precise control of the liquid flow and improving the user experience.

[0069] In one possible technical solution, the liquid measuring device further includes a first electrode and a second electrode, which are disposed in the housing and located at the vent hole; wherein, based on the liquid filling the receiving cavity, the liquid is connected to the first electrode and the second electrode, and the first switch closes the liquid inlet.

[0070] In this technical solution, the liquid measuring device further includes a first electrode and a second electrode. Specifically, the first and second electrodes are mounted on the housing and located at the vent. Specifically, when the liquid fills the receiving cavity, the liquid becomes conductive to the first and second electrodes. This closes the inlet, preventing further liquid intake and thus preventing leakage from the vent after the receiving cavity is full. Furthermore, the conductive connection between the liquid and the first and second electrodes when the receiving cavity is full allows for detection of whether the cavity is full, achieving precise control of the quantitative liquid intake and improving the user experience.

[0071] Specifically, the first and second electrodes have opposite polarities and are connected to the control module. When the liquid is connected to the first and second electrodes, the control module controls the driving component to operate. The driving component drives the movable component from the first position to the second position, and the first switch closes the liquid inlet, thus preventing liquid from entering the container and preventing leakage from the vent after the container is full. Furthermore, when the container is full, the liquid is connected to the first and second electrodes, allowing for detection of whether the container is full, achieving precise control of quantitative liquid intake and improving the user experience.

[0072] In one possible technical solution, the housing includes a first housing body, a second housing body, and a sealing element, wherein the liquid inlet is located on the first housing body, the second housing body is located below the first housing body and connected to the first housing body to form a receiving cavity, the liquid outlet is located on the second housing body, and the sealing element is located between the first housing body and the second housing body.

[0073] In this technical solution, the housing is defined as including a first housing body, a second housing body, and a sealing element. Specifically, the second housing body is connected to the first housing body and is located below the first housing body. The liquid inlet is located on the first housing body, and the liquid outlet is located on the second housing body. That is, the liquid inlet is located above the receiving cavity, and the liquid outlet is located below the receiving cavity. Thus, when liquid enters or exits through the liquid inlet and outlet, the quantitative liquid delivery can be achieved by utilizing gravity, eliminating the need for components such as water pumps used in related technologies for liquid pumping. This further simplifies the structure of the liquid measuring device and reduces the production cost of the liquid measuring device and the cooking appliance incorporating it.

[0074] Furthermore, a seal is provided at the connection between the first shell body and the second shell body to prevent liquid from leaking from the connection between the first shell body and the second shell body, thereby improving the sealing performance of the receiving cavity.

[0075] In practical applications, the first shell body and the second shell body are detachably connected, which allows for regular cleaning of the receiving cavity and improves the user experience.

[0076] Furthermore, the first and second shell bodies can be a single integrated structure. It is understood that a single integrated structure possesses superior mechanical properties, thereby ensuring the airtightness of the cavity. In addition, a single integrated structure facilitates manufacturing, thus reducing the production cost of the liquid measuring device and the cooking appliance incorporating it.

[0077] In one possible technical solution, the liquid measuring device also includes a liquid storage tank located above the housing, and the liquid storage tank has an outlet that can be connected to the liquid inlet.

[0078] In this technical solution, the liquid measuring device further includes a storage tank. Specifically, the storage tank is located above the housing and has an outlet that connects to the inlet. Thus, when the inlet is open, the liquid in the storage tank can enter the receiving cavity through the outlet and the inlet. Furthermore, because the storage tank is located above the housing, gravity can be used to achieve the quantitative entry of liquid, eliminating the need for pumps or other components used in related technologies. This further simplifies the structure of the liquid measuring device and reduces the production cost of the device and the cooking appliance incorporating it.

[0079] In practical applications, the outlet and inlet are designed to be directly connected. This reduces the liquid's flow path and improves the efficiency of quantitative liquid delivery. A sealing silicone sealant can be installed on the outside of the outlet-inlet connection to prevent leakage at the connection point as the liquid flows from the outlet to the inlet into the receiving cavity, thus improving the user experience.

[0080] It should be noted that the storage tank can be a water tank.

[0081] In one possible technical solution, the liquid measuring device also includes a support frame located between the housing and the liquid storage tank, and connected to both the housing and the liquid storage tank.

[0082] In this technical solution, the liquid measuring device also includes a support frame. Specifically, the support frame is positioned between the housing and the liquid storage tank, and is connected to both the housing and the liquid storage tank. This secures the housing and the liquid storage tank, improving the installation stability of the liquid measuring device. Furthermore, the liquid storage tank is located above the support frame, allowing the support frame to provide support for the liquid storage tank, thereby ensuring the installation stability and reliability of the liquid storage tank.

[0083] According to a second aspect of the present invention, a cooking appliance is provided, comprising a liquid measuring device as provided in any of the above-described technical solutions, and thus possessing all the beneficial technical effects of the liquid measuring device, which will not be elaborated further here.

[0084] Furthermore, the cooking appliance also includes a pot body and a second pipeline, wherein the pot body is located below the liquid measuring device and has a cooking chamber, and the two ends of the second pipeline are connected to the liquid outlet and the cooking chamber, respectively.

[0085] The cooking appliance provided in this invention includes a liquid measuring device, a pot body, and a second pipeline. Specifically, the pot body is located below the liquid measuring device, so that when the liquid filling the receiving cavity is completed, the inlet is closed, and the outlet is opened, the liquid in the receiving cavity flows out from the outlet to the pot body due to gravity, achieving quantitative liquid delivery. Furthermore, it eliminates the need for components such as water pumps used in related technologies to pump the liquid, further simplifying the structure of the cooking appliance and reducing its production cost. Further, the pot body has a cooking cavity, and one end of the second pipeline is connected to the outlet, while the other end of the second pipeline is connected to the cooking cavity, so that when liquid flows out from the outlet, it can flow into the cooking cavity through the second pipeline, achieving quantitative liquid delivery.

[0086] In one possible technical solution, the cooking appliance also includes a cleaning chamber that can communicate with the cooking cavity and can be used to clean food.

[0087] In this technical solution, a cleaning chamber is included to enable automatic cooking. Specifically, the cleaning chamber is connected to a water inlet device. After the user places the food into the cleaning chamber, the water inlet device automatically supplies water to clean the food. The cleaning chamber also has a drainage device to drain dirty water after cleaning. Furthermore, the cleaning chamber has a food conveying channel that connects to the cooking cavity. Cleaned food is then conveyed into the cooking cavity for further cooking. This achieves automatic cooking functionality and enhances the user experience.

Detailed Implementation

[0106] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0107] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0108] The following reference Figures 1 to 14 To describe the liquid measuring device 100 and cooking utensil 300 provided according to some embodiments of the present invention.

[0109] Example 1:

[0110] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, an embodiment of the first aspect of the present invention provides a liquid measuring device 100, which includes: a housing 110 having a receiving cavity 111; an inlet 120 and an outlet 130 disposed on the housing 110, the inlet 120 and the outlet 130 respectively communicating with the receiving cavity 111; and a switching assembly 140 movable relative to the housing 110 between a first position and a second position; wherein, based on the first position, the switching assembly 140 opens the inlet 120 and closes the outlet 130; and based on the second position, the switching assembly 140 closes the inlet 120 and opens the outlet 130.

[0111] The liquid measuring device 100 provided in this embodiment of the invention includes a housing 110, a liquid inlet 120, a liquid outlet 130, and a switching assembly 140. Specifically, the housing 110 is provided with a receiving cavity 111, which can contain liquid. The housing 110 is also provided with a liquid inlet 120, which is connected to the receiving cavity 111, that is, liquid enters the receiving cavity 111 through the liquid inlet 120. The housing 110 is also provided with a liquid outlet 130, which is connected to the receiving cavity 111, that is, after the receiving cavity 111 is filled with liquid, it is discharged from the receiving cavity 111 through the liquid outlet 130.

[0112] The switching assembly 140 is movable relative to the housing 110 and controls the opening and closing states of the inlet 120 and outlet 130 during its movement, thereby achieving quantitative liquid delivery. Specifically, the switching assembly 140 can move between a first position and a second position. When the switching assembly 140 is in the first position, it opens the inlet 120 and closes the outlet 130, allowing liquid to enter the receiving cavity 111 from the inlet 120. When the receiving cavity 111 is full of liquid, the switching assembly 140 moves from the first position to the second position. At this time, it opens the outlet 130 and closes the inlet 120, allowing liquid in the receiving cavity 111 to flow out from the outlet 130, thus achieving quantitative liquid delivery.

[0113] It is understandable that the volume of the receiving cavity 111 is fixed. When the liquid fills the measuring cavity, the volume of the liquid is deterministic. Therefore, the total volume of liquid delivered can be calculated based on the number of times liquid is delivered to the receiving cavity 111, thereby achieving precise control over the volume of liquid delivered. When delivering cooking water, this effectively prevents the problem of reduced rice texture due to excessive water volume delivered to the pot 310 of the cooking appliance 300. Furthermore, it effectively prevents the problem of undercooked rice due to insufficient water volume delivered to the pot 310 of the cooking appliance 300. This improves the user experience of the cooking appliance 300.

[0114] Furthermore, by controlling the opening and closing states of the inlet 120 and outlet 130 during the movement of the switch assembly 140, a quantitative liquid delivery can be achieved. This eliminates the need to use components such as flow meters in related technologies to measure the liquid volume, simplifying the structure of the liquid measuring device 100 and reducing the production costs of the liquid measuring device 100 and the cooking appliance 300 equipped with the liquid measuring device 100.

[0115] In practical applications, the inlet 120 is located above the receiving cavity 111, the outlet 130 is located below the receiving cavity 111, and the storage tank 200 is located above the inlet 120. Thus, when the inlet 120 is opened, the liquid enters the receiving cavity 111 through the inlet 120 due to gravity, eliminating the need for components such as water pumps in related technologies to pump the liquid. This further simplifies the structure of the liquid measuring device 100 and reduces the production cost of the liquid measuring device 100 and the cooking appliance 300 with the liquid measuring device 100.

[0116] The pot body 310 of the cooking appliance 300 is located below the housing 110. When the liquid outlet 130 is opened, the liquid in the receiving cavity 111 flows out from the liquid outlet 130 to the pot body 310 due to gravity, thus achieving the delivery of a fixed amount of liquid. Furthermore, it eliminates the need for components such as water pumps used in related technologies to pump the liquid, further simplifying the structure of the liquid measuring device 100 and reducing the production cost of the liquid measuring device 100 and the cooking appliance 300 equipped with it.

[0117] It should be noted that when the measuring device 100 is applied to the cooking appliance 300, the volume of the receiving cavity 111 is the minimum amount of water that needs to be added when cooking. In other words, the volume delivered by the measuring device 100 at one time is the minimum amount of water that needs to be added when cooking, thereby preventing the problem of excessive water intake due to an overly large volume of the measuring cavity 111, which would affect the taste of the cooked food.

[0118] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, based on the above embodiment, the switch assembly 140 further includes a first switch element 141, a second switch element 142, and a movable element 143. The first switch element 141 is located at the liquid inlet 120, the second switch element 142 is located at the liquid outlet 130, and at least a portion of the movable element 143 is located within the receiving cavity 111 and is movable relative to the housing 110 between a first position and a second position. When the movable element 143 is in the first position, the first switch element 141 opens the liquid inlet 120, and the second switch element 142 closes the liquid outlet 130; when the movable element 143 is in the second position, the first switch element 141 closes the liquid inlet 120, and the second switch element 142 opens the liquid outlet 130.

[0119] In this embodiment, the switch assembly 140 includes a first switch element 141, a second switch element 142, and a movable element 143. Specifically, the first switch element 141 is located at the liquid inlet 120, and it is understood that the first switch element 141 can open or close the liquid inlet 120. The second switch element 142 is located at the liquid outlet 130, and it is understood that the second switch element 142 can open or close the liquid outlet 130. Further, the movable element 143 is movable relative to the housing 110, and during the movement of the movable element 143, it can drive the first switch element 141 and the second switch element 142 to move, thereby enabling the first switch element 141 and the second switch element 142 to control the opening and closing states of the liquid inlet 120 and the liquid outlet 130, realizing the delivery of a quantitative amount of liquid.

[0120] Specifically, when the movable part 143 is in the first position, the first switch 141 opens the liquid inlet 120, and the second switch 142 closes the liquid outlet 130. Liquid enters the receiving cavity 111 from the liquid inlet 120. When the receiving cavity 111 is full, the movable part 143 moves from the first position to the second position. The first switch 141 closes the liquid inlet 120, and the second switch 142 opens the liquid outlet 130. Liquid in the receiving cavity 111 flows out from the liquid outlet 130, achieving quantitative liquid delivery. The total volume of liquid delivered is calculated based on the number of times liquid is delivered to the receiving cavity 111, thus achieving precise control of the delivered liquid volume. When delivering cooking water, this effectively prevents the problem of reduced rice texture due to excessive water volume delivered to the pot 310 of the cooking appliance 300. Furthermore, it effectively prevents the problem of undercooked rice due to insufficient water volume delivered to the pot 310 of the cooking appliance 300. Improve the user experience of cooking appliance 300.

[0121] Furthermore, by controlling the opening and closing states of the inlet 120 and outlet 130 during the movement of the switch assembly 140, a quantitative liquid delivery can be achieved. This eliminates the need to use components such as flow meters in related technologies to measure the liquid volume, simplifying the structure of the liquid measuring device 100 and reducing the production costs of the liquid measuring device 100 and the cooking appliance 300 equipped with the liquid measuring device 100.

[0122] In practical applications, the first switching element 141 is a first check valve, the second switching element 142 is a second check valve, and the movable element 143 is located within the receiving cavity 111. A portion of both the first and second check valves is located within the receiving cavity 111. During the movement of the movable element 143, it pushes the first and second check valves to move away from the receiving cavity 111. Specifically, when the movable element 143 contacts the first check valve, it can push the check valve to open the inlet 120. When the movable element 143 disengages from the first check valve, the first check valve resets and closes the inlet 120. Similarly, when the movable element 143 contacts the second check valve, it can push the check valve to open the outlet 130. When the movable element 143 disengages from the second check valve, the second check valve resets and closes the outlet 130.

[0123] In detail, when the movable part 143 is in the first position, it abuts against the first check valve, while simultaneously not abutting against the second check valve. The first check valve opens the inlet 120, and the second check valve closes the outlet 130. Liquid enters the receiving chamber 111 through the inlet 120. When the receiving chamber 111 is full of liquid, the movable part 143 moves from the first position to the second position, disengaging from the first check valve. The first check valve closes the inlet 120, and simultaneously abuts against the second check valve, opening the outlet 130. This achieves the delivery of a fixed quantity of liquid.

[0124] Additionally, a first magnet may be provided on the side of the first switch 141 facing the receiving cavity 111, a second magnet may be provided on the side of the second switch 142 facing the receiving cavity 111, and a first magnetic conductive part may be provided on the side of the movable part 143 facing the first switch 141, and a second magnetic conductive part may be provided on the side of the movable part 143 facing the second switch 142. The first magnet and the first magnetic conductive part are magnetically repelled, and the second magnet and the second magnetic conductive part are magnetically repelled. Specifically, when the movable part 143 is in the first position, the first magnetic conductive part on the movable part 143 and the first magnet on the first switch 141 are magnetically repelled, thereby pushing the first switch 141 to move away from the receiving cavity 111 to open the liquid inlet 120. Simultaneously, the second magnet on the second switch 142 and the second magnetic conductive part on the movable part 143 are not in contact, and the liquid outlet 130 is closed.

[0125] When the receiving cavity 111 is filled with liquid, the movable member 143 moves from the first position to the second position. The second magnetic part on the movable member 143 magnetically repels the second magnet on the second switch member 142, thereby pushing the second switch member 142 to move away from the receiving cavity 111 to open the liquid outlet 130. At the same time, the first magnet on the first switch member 141 does not contact the first magnetic part on the movable member 143, and the liquid inlet 120 is closed. This achieves the delivery of a fixed amount of liquid. The specific structure of the switch member and the movable member 143 can be set according to actual needs.

[0126] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, in a specific embodiment, the first switching element 141 is a first check valve, and the second switching element 142 is a second check valve. Specifically, when the movable element 143 is in the first position, it abuts against the first check valve, opening the inlet 120; when the movable element 143 disengages from the second check valve, the second check valve closes the outlet 130. When the movable element 143 is in the second position, it abuts against the second check valve, opening the outlet 130; when the movable element 143 disengages from the first check valve, the first check valve closes the inlet 120.

[0127] In this embodiment, the first switching element 141 is defined as a first check valve, the second switching element 142 as a second check valve, and the movable element 143 is located within the receiving cavity 111. A portion of both the first and second check valves is located within the receiving cavity 111. During the movement of the movable element 143, the first and second check valves are pushed to move away from the receiving cavity 111. Specifically, when the movable element 143 contacts the first check valve, it can push the check valve to move, causing the first check valve to open the inlet 120. When the movable element 143 disengages from the first check valve, the first check valve resets and closes the inlet 120. Similarly, when the movable element 143 contacts the second check valve, it can push the check valve to move, causing the second check valve to open the outlet 130. When the movable element 143 disengages from the second check valve, the second check valve resets and closes the outlet 130.

[0128] In detail, when the movable part 143 is in the first position, it abuts against the first one-way valve, while simultaneously not abutting against the second one-way valve. The first one-way valve opens the inlet 120, and the second one-way valve closes the outlet 130. Liquid enters the receiving cavity 111 through the inlet 120. When the receiving cavity 111 is full of liquid, the movable part 143 moves from the first position to the second position, disengaging from the first one-way valve. The first one-way valve closes the inlet 120, and simultaneously abuts against the second one-way valve, opening the outlet 130. This achieves the quantitative delivery of liquid. The total volume of liquid delivered is calculated based on the number of times liquid is delivered to the receiving cavity 111, thus achieving precise control of the delivered liquid volume. When delivering cooking water, this effectively prevents the problem of reduced rice texture due to excessive water volume delivered to the pot 310 of the cooking appliance 300. Furthermore, it can effectively prevent the problem of undercooked rice due to insufficient water volume in the pot 310 of the cooking appliance 300, thus improving the user experience of the cooking appliance 300.

[0129] Furthermore, the liquid volume measurement can be simplified by eliminating the need for components such as flow meters in related technologies, thereby reducing the production costs of the liquid measuring device 100 and the cooking appliance 300 equipped with the liquid measuring device 100.

[0130] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, based on the above embodiment, the liquid measuring device 100 further includes a driving member 150, which is connected to the movable member 143. The driving member 150 can drive the movable member 143 to move between a first position and a second position.

[0131] In this embodiment, the liquid measuring device 100 is further defined as including a driving member 150. Specifically, the driving member 150 is connected to the movable member 143, so that under the drive of the driving member 150, the movable member 143 can move relative to the housing 110, thereby enabling the first switch member 141 and the second switch member 142 to control the opening and closing states of the liquid inlet 120 and the liquid outlet 130, and realize the delivery of a quantitative liquid.

[0132] Driven by the driving component 150, the movable component 143 can move between a first position and a second position. Specifically, when the movable component 143 is in the first position, the first switch 141 opens the liquid inlet 120, and the second switch 142 closes the liquid outlet 130. Liquid enters the receiving cavity 111 from the liquid inlet 120. When the receiving cavity 111 is full, the movable component 143 moves from the first position to the second position. The first switch 141 closes the liquid inlet 120, and the second switch 142 opens the liquid outlet 130. Liquid in the receiving cavity 111 flows out from the liquid outlet 130, realizing the quantitative delivery of liquid. The total volume of liquid delivered is calculated based on the number of times liquid is delivered to the receiving cavity 111, thereby achieving precise control of the delivered liquid volume. When delivering cooking water, this effectively prevents the problem of reduced rice texture due to excessive water volume delivered to the pot body 310 of the cooking appliance 300. Furthermore, it can effectively prevent the problem of undercooked rice due to insufficient water volume in the pot 310 of the cooking appliance 300, thus improving the user experience of the cooking appliance 300.

[0133] Furthermore, by controlling the opening and closing states of the inlet 120 and outlet 130 during the movement of the switch assembly 140, a quantitative liquid delivery can be achieved. This eliminates the need to use components such as flow meters in related technologies to measure the liquid volume, simplifying the structure of the liquid measuring device 100 and reducing the production costs of the liquid measuring device 100 and the cooking appliance 300 equipped with the liquid measuring device 100.

[0134] In specific applications, the first driving component 150 is a motor and is disposed outside the housing 110. Specifically, the housing 110 is provided with a transmission hole, through which the movable component 143 is connected to the motor, so that under the drive of the motor, the movable component 143 can move between a first position and a second position. In addition, the liquid measuring device 100 may include a transmission gear set, through which the movable component 143 is connected to the motor, thereby enabling precise control of the movement position of the movable component 143, thereby improving the stability and reliability of quantitative liquid delivery.

[0135] Example 2:

[0136] Based on the above embodiments, the liquid measuring device 100 further includes a detection device, which is disposed in the housing 110 and connected to the drive member 150. The detection device can detect the movement position of the movable member 143 and control the working state of the drive member 150 according to the movement position of the movable member 143.

[0137] In this embodiment, the liquid measuring device 100 is further defined as including a detection device. Specifically, the detection device is disposed on the housing 110 and is connected to the drive member 150. The working state of the drive member 150 is controlled by detecting the position of the movable member 143, thereby realizing quantitative liquid delivery and facilitating the control of the movement position of the movable member 143. The structure is simple and the operation is convenient.

[0138] Specifically, when the detection device detects that the movable part 143 has moved to the first position, the control drive 150 stops driving the movable part 143, causing the movable part 143 to stop at the first position. This causes the first switch 141 to open the inlet 120 and the second switch 142 to close the outlet 130, allowing liquid to enter the receiving cavity 111 through the inlet 120. When the receiving cavity 111 is full of liquid, the drive 150 continues to drive the movable part 143. When the detection device detects that the movable part 143 has moved to the second position, the control drive 150 stops driving, causing the movable part 143 to stop at the second position. This causes the first switch 141 to close the inlet 120 and the second switch 142 to open the outlet 130. Thus, by controlling the position of the movable part 143 detected by the detection device, the working state of the drive 150 is controlled, achieving quantitative liquid delivery while facilitating the control of the movable part 143's movement. The structure is simple and the operation is convenient.

[0139] Example 3:

[0140] like Figure 4 As shown, based on the above embodiments, the detection device further includes a control module, a third switch 161, and a fourth switch 162. The control module is connected to the drive unit 150, and the third switch 161 and the fourth switch 162 are disposed on the housing 110. When the movable member 143 is in a first position, a portion of the movable member 143 triggers the third switch 161, and the drive unit 150 stops working. When the movable member 143 is in a second position, a portion of the movable member 143 triggers the fourth switch 162, and the drive unit 150 stops working.

[0141] In this embodiment, the detection device includes a control module, a third switch 161, and a fourth switch 162. Specifically, the drive unit 150 is connected to the control module, and the third switch 161 and the fourth switch 162 are disposed on the housing 110. Specifically, when the movable member 143 moves to the first position, a portion of the movable member 143 can trigger the third switch 161, which sends a signal to the control module. The control module then controls the drive unit 150 to stop driving. This causes the movable member 143 to remain in the first position, thereby causing the first switch 141 to open the liquid inlet 120 and the second switch 142 to close the liquid outlet 130, allowing liquid to enter the receiving cavity 111 through the liquid inlet 120.

[0142] When the receiving cavity 111 is filled with liquid, the driving component 150 drives the movable component 143 to continue moving. When the movable component 143 moves to the second position, a portion of the movable component 143 can trigger the fourth switch 162. The fourth switch 162 sends a signal to the control module, which controls the driving component 150 to stop driving, thereby causing the movable component 143 to stop at the second position. This causes the first switch 141 to close the inlet 120 and the second switch 142 to open the outlet 130. Thus, by detecting the position of the movable component 143, the working state of the driving component 150 is controlled, achieving quantitative liquid delivery while facilitating the control of the movable component 143's movement. The structure is simple and the operation is convenient.

[0143] like Figure 4 and Figure 10 As shown, based on the above embodiment, the movable member 143 further includes a movable part 1431 and a trigger part 1432. The movable part 1431 is located inside the receiving cavity 111, and the trigger part 1432 is connected to the movable part 1431 and located outside the receiving cavity 111. The movement of the movable part 1431 can drive the movement of the trigger part 1432. Specifically, when the movable member 143 is in the first position, the trigger part 1432 triggers the third switch 161, and the drive member 150 stops working; when the movable member 143 is in the second position, the trigger part 1432 triggers the fourth switch 162, and the drive member 150 stops working.

[0144] In this embodiment, the movable member 143 is defined as including a movable part 1431 and a trigger part 1432. Specifically, the movable part 1431 is connected to the trigger part 1432. Under the drive of the driving member 150, the movable part 1431 can drive the trigger part 1432 to move. Specifically, when the movable member 143 moves to the first position, the trigger part 1432 can trigger the third switch 161. The third switch 161 sends a signal to the control module, and the control module controls the driving member 150 to stop driving. This causes the movable member 143 to stop at the first position, thereby causing the first switch 141 to open the liquid inlet 120 and the second switch 142 to close the liquid outlet 130, allowing liquid to enter the receiving cavity 111 through the liquid inlet 120.

[0145] When the receiving cavity 111 is filled with liquid, the driving component 150 drives the movable component 143 to continue moving. When the movable component 143 moves to the second position, the triggering part 1432 can trigger the fourth switch 162. The fourth switch 162 sends a signal to the control module, which controls the driving component 150 to stop driving, thereby causing the movable component 143 to stop at the second position. This causes the first switch 141 to close the liquid inlet 120 and the second switch 142 to open the liquid outlet 130. Thus, by detecting the position of the movable component 143, the working state of the driving component 150 is controlled, achieving quantitative liquid delivery while facilitating the control of the movable component 143's movement. The structure is simple and the operation is convenient.

[0146] It should be noted that the movable part 1431 is located inside the receiving cavity 111, and the trigger part 1432 is located outside the receiving cavity 111. It is understood that the housing 110 has a mounting hole through which the movable part 1431 and the trigger part 1432 are connected. The measuring device 100 also includes sealing silicone, which seals the mounting hole to prevent liquid in the receiving cavity 111 from leaking from the mounting hole.

[0147] Example 4:

[0148] like Figure 9 Furthermore, based on the above embodiment, the movable part 1431 is provided with a connecting cavity 1433, and at least a portion of the driving member 150 extends into the connecting cavity 1433. The driving member 150 can drive the movable part 1431 to rotate around the axis of the connecting cavity 1433.

[0149] In this embodiment, the structure of the movable part 1431 is further defined. The movable part 1431 is provided with a connecting cavity 1433, which is located on the side of the movable part 1431 facing the driving member 150. The driving member 150 is provided with a driving shaft, which can extend into the connecting cavity 1433, thereby connecting the driving shaft to the movable part 1431 through the connecting cavity 1433. The driving shaft can drive the movable part to rotate. As the driving shaft rotates, it can drive the movable part 1431 to rotate around the axis of the connecting cavity 1433. In turn, the movable part 1431 drives the trigger part to move, thereby realizing the movement of the movable member 143 between a first position and a second position.

[0150] Furthermore, the movable part 1431 is also provided with a positioning protrusion 1434, which is located at one end of the movable part 1431 away from the connecting cavity 1433. The housing 110 is provided with a positioning groove 115 that is adapted to the positioning protrusion 1434, and at least part of the positioning protrusion 1434 extends into the positioning groove 115.

[0151] In this embodiment, to ensure the stability of the movable part 1431 during rotation, a positioning protrusion 1434 for positioning is also included in the movable part 1431. Specifically, the positioning protrusion 1434 is located at the end of the movable part 1431 away from the connecting cavity 1433. A positioning groove 115 adapted to the positioning protrusion 1434 is provided on the housing 110. At least part of the positioning protrusion 1434 extends into the positioning groove 115, thereby enabling the positioning of the movable part 1431 through the cooperation of the positioning protrusion 1434 and the positioning groove 115, and preventing the movable part 1431 from becoming unstable during rotation.

[0152] Example 5:

[0153] Based on Embodiment 2, in one possible design, the detection device includes:

[0154] The control module is connected to the drive component 150. When the movable component 143 is in the first position or the second position, the control module can control the drive component 150 to stop for a preset time.

[0155] In this design, the detection device includes a control module connected to the drive component 150. The control module can control the stopping duration of the drive component 150. Specifically, when the movable component 143 is in the first or second position, the movable component 143 can open or close the inlet 120 or the outlet 130. Therefore, while keeping the flow rates of the inlet 120 and the outlet 130 constant, by controlling the stopping duration of the movable component 143 in the first or second position, the inlet flow rate of the inlet 120 and the outlet flow rate of the outlet 130 can be controlled.

[0156] Example 6:

[0157] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 13 As shown, based on the above embodiment, the liquid measuring device 100 further includes an exhaust port 170, which is disposed in the housing 110 and communicates with the receiving cavity 111.

[0158] In this embodiment, the liquid measuring device 100 further includes a vent 170. Specifically, the vent 170 is disposed on the housing 110, with one end connected to the receiving cavity 111 and the other end connected to the outside. By providing the vent 170, the air pressure inside the receiving cavity 111 can be kept balanced with the outside, thereby ensuring that liquid can enter the receiving cavity 111 from the inlet 120. This prevents the receiving cavity 111 from failing to fill due to trapped air, thus improving the reliability of quantitative liquid delivery.

[0159] In practical applications, the vent 170 is located at the top of the housing 110 to ensure that the liquid can fill the receiving cavity 111, thereby achieving the delivery of a fixed quantity of liquid. It should be noted that the number of vents 170 can be set as needed.

[0160] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 13 As shown, based on the above embodiments, the liquid measuring device 100 further includes an exhaust member 180 and a float 190. The exhaust member 180 is connected to the housing 110, and the exhaust member 180 has a mounting cavity 181. The first end of the mounting cavity 181 is connected to the exhaust port 170, and the second end of the mounting cavity 181 can be connected to the outside. The float 190 is located in the mounting cavity 181 and can float with the liquid surface to open or seal the second end of the mounting cavity 181.

[0161] In this embodiment, the liquid measuring device 100 further includes an vent 180 and a float 190. Specifically, the vent 180 is disposed on the housing 110, and the vent 180 has a mounting cavity 181. Specifically, one end of the mounting cavity 181 is connected to the vent hole 170, and the vent hole 170 is connected to the receiving cavity 111. That is, one end of the mounting cavity 181 is connected to the receiving cavity 111 through the vent hole 170. The other end of the mounting cavity 181 can be connected to the outside, thereby ensuring that liquid can enter the receiving cavity 111 from the liquid inlet 120, preventing the receiving cavity 111 from not being filled due to air trapped inside, and improving the reliability of quantitative liquid delivery.

[0162] Furthermore, the float 190 is located inside the mounting cavity 181 and can float with the liquid surface. Specifically, when the receiving cavity 111 is filled with liquid, the liquid flows out from the vent hole 170 into the mounting cavity 181. After the float 190 floats to a preset position with the liquid surface, it seals the end of the mounting cavity 181 that is connected to the outside. That is, the float 190 seals the mounting cavity 181, so that the liquid no longer enters the receiving cavity 111. While realizing the quantitative liquid delivery, the receiving cavity 111 is sealed to prevent the liquid from leaking from the vent hole 170 and the mounting cavity 181.

[0163] When the liquid in the receiving cavity 111 is discharged from the outlet 130, the liquid in the receiving cavity 111 gradually decreases. Some of the liquid in the mounting cavity 181 flows back into the receiving cavity 111. The float 190 opens the mounting cavity 181 to keep the air pressure in the receiving cavity 111 balanced with the outside, ensuring that the liquid flows out smoothly from the outlet 130 and improving the stability and reliability of quantitative liquid delivery.

[0164] It should be noted that the second end of the mounting cavity 181 is provided with a mounting port that communicates with the outside. The width of the float 190 is greater than the width of the mounting port. Therefore, when the float 190 floats to the position of the mounting port with the liquid surface, the float 190 can be stuck at the position of the mounting port, thereby achieving the sealing of the mounting cavity 181 and the receiving cavity 111.

[0165] In one specific embodiment, the float 190 is further a buoyancy ball; the venting component 180 is provided with an venting channel, which is connected to the second end of the mounting cavity 181, and the width of the venting channel is smaller than the diameter of the buoyancy ball.

[0166] In this embodiment, the float 190 is defined as a buoyancy ball. It is understood that the buoyancy ball has a symmetrical structure, and when it floats on the liquid surface, it facilitates cooperation with the connection between the exhaust channel and the second end of the mounting cavity 181. This ensures gas flow inside and outside the receiving cavity 111 while simultaneously sealing the mounting cavity 181 and the receiving cavity 111. This further prevents liquid leakage and improves the stability and reliability of quantitative liquid delivery.

[0167] Furthermore, the venting component 180 is provided with an venting channel, which is connected to the second end of the mounting cavity 181. In other words, the second end of the mounting cavity 181 is connected to the outside through the venting channel. The width of the venting channel is smaller than the diameter of the buoyancy ball, so that when the buoyancy ball floats to the connection between the venting channel and the second end of the mounting cavity 181, the float 190 can be engaged at the connection, ensuring gas flow inside and outside the receiving cavity 111 while simultaneously sealing the mounting cavity 181 and the receiving cavity 111. This further prevents liquid leakage and improves the stability and reliability of quantitative liquid delivery.

[0168] In another specific embodiment, the liquid measuring device 100 further includes a first conduit connected to the end of the vent 180 opposite to the vent hole 170 and connected to the vent passage.

[0169] In this embodiment, the liquid measuring device 100 is further defined as including a first pipe. Specifically, the first pipe is connected to the end of the vent 180 away from the vent hole 170, and the first pipe is connected to the vent passage. So when the liquid fills the receiving cavity 111 and the float 190 seals the second end of the mounting cavity 181, the first pipe can receive the liquid that seeps out between the float 190 and the vent 180, thereby preventing the seeping liquid from flowing to other parts of the cooking appliance 300 and reducing the user experience.

[0170] In practical applications, one end of the first pipe is connected to the exhaust channel, and the other end is connected to the rice-washing water drain channel of the cooking appliance 300, allowing the leaked liquid to be drained along with the rice-washing water. This further prevents the leaked liquid from flowing to other parts of the cooking appliance 300 and thus reducing the user experience.

[0171] In a specific embodiment, the float 190 further includes a pressing part; the liquid measuring device 100 also includes a fifth switch element located in the mounting cavity 181. When the float 190 floats to a preset position with the liquid surface, the pressing part can trigger the fifth switch element to close the liquid inlet 120.

[0172] In this embodiment, the liquid measuring device 100 further includes a fifth switching element. Specifically, the fifth switching element is disposed within the mounting cavity 181. When the float 190 floats to a preset position with the liquid surface, the pressing part on the float 190 can trigger the fifth switching element, thereby closing the liquid inlet 120 and stopping liquid from entering the receiving cavity 111. This prevents leakage from the vent 170 after the receiving cavity 111 is full. Furthermore, when the receiving cavity 111 is full, the pressing part can trigger the fifth switching element, thereby enabling detection of whether the receiving cavity 111 is full, achieving precise control of quantitative liquid intake, and improving the user experience.

[0173] Specifically, the fifth switch can be connected to the control module. When the pressure point triggers the fifth switch, it transmits a signal to the control module. The control module then controls the drive unit 150 to operate. The drive unit 150 drives the movable part 143 from the first position to the second position, and the first switch 141 closes the liquid inlet 120, thus preventing liquid from entering the receiving cavity 111. This prevents leakage from the vent 170 after the receiving cavity 111 is full. Furthermore, when the receiving cavity 111 is full, the pressure point can trigger the fifth switch, enabling detection of whether the receiving cavity 111 is full, achieving precise control of quantitative liquid intake, and improving the user experience.

[0174] In another specific embodiment, the liquid measuring device 100 further includes a first electrode and a second electrode, which are disposed in the housing 110 and located at the vent 170; wherein, based on the liquid filling the receiving cavity 111, the liquid is connected to the first electrode and the second electrode, and the first switch 141 closes the liquid inlet 120.

[0175] In this embodiment, the liquid measuring device 100 further includes a first electrode and a second electrode. Specifically, the first electrode and the second electrode are disposed on the housing 110 and located at the vent hole 170. Specifically, when the liquid fills the receiving cavity 111, the liquid is connected to the first electrode and the second electrode. This closes the inlet 120, preventing further liquid from entering the receiving cavity 111 and thus preventing leakage from the vent hole 170 after the receiving cavity 111 is full. Furthermore, when the receiving cavity 111 is full, the liquid is connected to the first electrode and the second electrode, enabling detection of whether the receiving cavity 111 is full, achieving precise control of quantitative liquid intake, and improving the user experience.

[0176] Specifically, the first and second electrodes have opposite polarities and are connected to the control module. When the liquid is connected to the first and second electrodes, the control module controls the drive unit 150 to operate. The drive unit 150 drives the movable part 143 from the first position to the second position, and the first switch 141 closes the liquid inlet 120, thereby preventing liquid from entering the receiving cavity 111 and thus preventing leakage from the vent 170 after the receiving cavity 111 is full. Furthermore, when the receiving cavity 111 is full, the liquid is connected to the first and second electrodes, allowing for detection of whether the receiving cavity 111 is full, achieving precise control of quantitative liquid intake and improving the user experience.

[0177] Example 7:

[0178] like Figure 4As shown, based on the above embodiment, the housing 110 further includes a first housing body 112, a second housing body 113, and a sealing member 114. The liquid inlet 120 is located on the first housing body 112, the second housing body 113 is located below the first housing body 112 and is connected to the first housing body 112 to form a receiving cavity 111, the liquid outlet 130 is located on the second housing body 113, and the sealing member 114 is located between the first housing body 112 and the second housing body 113.

[0179] In this embodiment, the housing 110 is defined as including a first housing body 112, a second housing body 113, and a sealing member 114. Specifically, the second housing body 113 is connected to the first housing body 112 and is located below the first housing body 112. The liquid inlet 120 is located on the first housing body 112, and the liquid outlet 130 is located on the second housing body 113. That is, the liquid inlet 120 is located above the receiving cavity 111, and the liquid outlet 130 is located below the receiving cavity 111. Thus, when liquid enters or exits through the liquid inlet 120 and the liquid outlet 130, a quantitative liquid can be delivered by gravity, eliminating the need for components such as water pumps used in related technologies to pump the liquid. This further simplifies the structure of the liquid measuring device 100 and reduces the production cost of the liquid measuring device 100 and the cooking appliance 300 having the liquid measuring device 100.

[0180] Furthermore, a sealing element 114 is provided at the connection between the first shell body 112 and the second shell body 113, thereby preventing liquid from leaking from the connection between the first shell body 112 and the second shell body 113 and improving the sealing performance of the receiving cavity 111.

[0181] In practical applications, the first shell body 112 and the second shell body 113 are detachably connected, allowing for regular cleaning of the receiving cavity 111 and improving the user experience. Alternatively, the first shell body 112 and the second shell body 113 can be a single integrated structure. This integrated structure provides superior mechanical properties, ensuring the sealing of the receiving cavity 111. Furthermore, the integrated structure facilitates manufacturing, thereby reducing the production costs of the liquid measuring device 100 and the cooking utensil 300 incorporating it.

[0182] Example 8:

[0183] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, based on the above embodiments, the liquid measuring device 100 further includes a liquid storage tank 200, which is located above the housing 110. The liquid storage tank 200 has an outlet that can be connected to the liquid inlet 120.

[0184] In this embodiment, the liquid measuring device 100 further includes a liquid storage tank 200. Specifically, the liquid storage tank 200 is located above the housing 110 and has an outlet that can communicate with the liquid inlet 120. Thus, when the liquid inlet 120 is open, the liquid in the liquid storage tank 200 can enter the receiving cavity 111 through the outlet and the liquid inlet 120. Furthermore, since the liquid storage tank 200 is located above the housing 110, gravity can be used to achieve the quantitative entry of liquid, eliminating the need for pumps or other components used in related technologies. This further simplifies the structure of the liquid measuring device 100 and reduces the production cost of the liquid measuring device 100 and the cooking appliance 300 incorporating it.

[0185] In practical applications, the outlet and inlet 120 are connected. This reduces the liquid flow path and improves the efficiency of quantitative liquid delivery. A sealing silicone sealant can be installed on the outside of the connection between the outlet and inlet 120 to prevent leakage from the connection point during the liquid flow from the outlet to the receiving cavity 111, thus improving the user experience. It should be noted that the storage tank 200 can be a water tank.

[0186] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, based on the above embodiments, the liquid measuring device 100 further includes a support frame 210, which is located between the housing 110 and the liquid storage tank 200 and is connected to the housing 110 and the liquid storage tank 200.

[0187] In this embodiment, the liquid measuring device 100 further includes a support frame 210. Specifically, the support frame 210 is disposed between the housing 110 and the liquid storage tank 200, and is connected to both the liquid storage tank 200 and the housing 110. This secures the housing 110 and the liquid storage tank 200, improving the installation stability of the liquid measuring device 100. Furthermore, the liquid storage tank 200 is located above the support frame 210, allowing the support frame 210 to provide support for the liquid storage tank 200, thereby ensuring the installation stability and reliability of the liquid storage tank 200.

[0188] Example 9:

[0189] According to a second aspect of the present invention, a cooking utensil 300 is provided, which includes a liquid measuring device 100 as provided in any of the above-described technical solutions, and thus possesses all the beneficial technical effects of the liquid measuring device 100, which will not be repeated here.

[0190] like Figure 14 As shown, the cooking appliance 300 further includes a pot body 310 and a second pipeline. The pot body 310 is located below the liquid measuring device 100 and has a cooking chamber. The two ends of the second pipeline are connected to the liquid outlet 130 and the cooking chamber, respectively.

[0191] The cooking appliance 300 provided in this embodiment of the invention includes a liquid measuring device 100, a pot body 310, and a second pipeline. Specifically, the pot body 310 is located below the liquid measuring device 100, so that when the liquid filling the receiving cavity 111 is completed, the liquid inlet 120 is closed, and the liquid outlet 130 is opened, the liquid in the receiving cavity 111 flows out from the liquid outlet 130 to the pot body 310 due to gravity, thus realizing the delivery of a fixed amount of liquid. Furthermore, it eliminates the need for components such as water pumps used in related technologies to pump the liquid, further simplifying the structure of the cooking appliance 300 and reducing its production cost.

[0192] Furthermore, the pot body 310 is provided with a cooking chamber, one end of the second pipe is connected to the liquid outlet 130, and the other end of the second pipe is connected to the cooking chamber, so that when the liquid flows out from the liquid outlet 130, it can flow into the cooking chamber through the second pipe to realize the quantitative delivery of liquid.

[0193] It is understandable that the volume of the receiving cavity 111 is fixed. When the liquid fills the measuring cavity, the volume of the liquid is deterministic. Therefore, the total volume of liquid delivered can be calculated based on the number of times liquid is delivered to the receiving cavity 111, thereby achieving precise control over the volume of liquid delivered. When delivering cooking water, this effectively prevents the problem of reduced rice texture due to excessive water volume delivered to the pot 310 of the cooking appliance 300. Furthermore, it effectively prevents the problem of undercooked rice due to insufficient water volume delivered to the pot 310 of the cooking appliance 300. This improves the user experience of the cooking appliance 300.

[0194] Furthermore, by controlling the opening and closing states of the inlet 120 and outlet 130 during the movement of the switch assembly 140, a quantitative liquid delivery can be achieved. This eliminates the need to use components such as flow meters in related technologies to measure the liquid volume, simplifying the structure of the liquid measuring device 100 and reducing the production costs of the liquid measuring device 100 and the cooking appliance 300 equipped with the liquid measuring device 100.

[0195] In practical applications, the pot body 310 has a cooking cavity, which can be understood as a washing cavity. Materials can be washed through the cooking cavity of the pot body 310. After washing, the wastewater is drained, and cooking water is introduced back into the cooking cavity for direct cooking. Compared to related technologies that use a rice washing box to wash rice and then drain the washed rice into the inner pot, this effectively prevents the problem of residual rice remaining in the rice washing box, saving ingredients. Furthermore, using the cooking cavity of the pot body 310 for rice washing eliminates the need for a rice washing box or similar components on the cooking appliance 300, effectively simplifying the structure of the cooking appliance 300, reducing its space requirements, and improving the user experience.

[0196] In another possible embodiment, the cooking appliance 300 has a separate cleaning chamber, which is independent of the cooking chamber.

[0197] In this embodiment, to enable automatic cooking, the cooking appliance 300 also includes a cleaning chamber. Specifically, the cleaning chamber is connected to a water inlet device. After the user places the food into the cleaning chamber, the water inlet device automatically supplies water to the cleaning chamber to clean the food. The cleaning chamber also has a drainage device to drain dirty water after the food is cleaned. Furthermore, the cleaning chamber has a food conveying channel that connects to the cooking cavity. The cleaned food can be conveyed into the cooking cavity through the food conveying channel for the next step of cooking. Thus, the automatic cooking function of the cooking appliance 300 is realized, improving the user experience.

[0198] The cooking appliance 300 also includes a storage tank, specifically located above the pot body 310 and connected to the cooking chamber. The storage tank can hold ingredients such as rice grains. When it is necessary to transfer these ingredients to the cooking chamber, the storage tank can be opened to deliver them. By placing the storage tank above the pot body 310, gravity can be used to allow the ingredients to flow into the cooking chamber, eliminating the need for components such as fans to blow the ingredients. This simplifies the structure of the cooking appliance 300, reduces its space requirements, and consequently lowers its production costs. If the cooking appliance 300 includes a cleaning chamber, the storage tank and liquid storage tank can also be connected to the cleaning chamber.

[0199] In practical applications, the liquid storage tank is a water tank, and the material storage tank is a rice tank.

[0200] Furthermore, the cooking appliance 300 also includes a heating device, specifically located on the outside of the pot body 310, or more specifically, at the bottom of the pot body 310. The heating device can heat the cooking cavity, thereby heating the food inside and cooking it. By incorporating the heating device, after the food has been washed, it can be turned on to cook the food inside the cooking cavity, thus realizing the process of washing rice and cooking, improving the convenience of using the cooking appliance 300.

[0201] Furthermore, the cooking appliance 300 also includes a temperature detection device. Specifically, the temperature detection device is installed on the pot body 310 and can detect the temperature inside the cooking cavity. Therefore, it can control the heating power and heating time of the heating device based on the detected temperature inside the cooking cavity, further enhancing the intelligence of the cooking appliance 300. Specifically, the temperature detection device can directly detect the temperature inside the cooking cavity, or it can detect the temperature inside the cooking cavity by detecting the temperature of the inner pot of the pot body 310, which can be set according to actual needs.

[0202] In practical applications, the temperature detection device can be a temperature sensor. The temperature sensor can detect the temperature inside the inner pot or cooking cavity, and then control the heating power and heating time of the heating device based on the detected temperature, further enhancing the intelligence of the cooking appliance 300.
