[0037] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.

[0038] The magnetic valve assembly, a key component in the control system of a high-pressure cooker, is responsible for controlling the pressure within the cooker. In related technologies, magnetic valve assemblies for high-pressure cookers typically utilize a rigid package. Due to the significant differences in thermal expansion and contraction coefficients between different materials, the pressure cooker experiences unpredictable deformation during use, leading to uneven stress in the rigid package. This accumulated stress can eventually cause cracking, damaging and failing the magnetic valve.

[0039] For this reason, Figures 1 to 6 The figure shows the magnetic valve assembly proposed by the present invention, which includes a magnetic valve 100, a control assembly 200, and a floating assembly 300. The magnetic valve 100 is used to adjust the internal pressure of the electric pressure cooker, and the control assembly 200 is used to control the sealing and exhaust switching of the magnetic valve 100. When the control assembly 200 is energized, a magnetic field is generated. The magnetic valve 100 is located in the magnetic field generated by the control assembly 200. The magnetic valve 100 switches the sealing or exhaust state under the action of the magnetic field force of the control assembly 200, thereby adjusting the internal pressure of the electric pressure cooker and realizing precise control of the pressure in the pot. So that users can adjust the electric pressure cooker according to the different cooking pressure requirements of different ingredients and different tastes, the magnetic valve 100 and the control component 200 are encapsulated by the floating component 300. The floating component 300 includes an elastic connector 310. The elastic connector 310 is sleeved on the magnetic valve 100 and in contact with the control component 200. The magnetic valve 100 and the control component 200 are deformed due to thermal expansion and contraction. The elastic connector 310 can elastically deform to absorb the deformation of the magnetic valve 100 and the control component 200, thereby extending the service life of the magnetic valve component.

[0040] In some embodiments of the present invention, the elastic connector 310 can absorb deformation of the magnetic valve 100 and the control assembly 200. It can be made of an elastic material such as rubber, silicone, or a thermoplastic elastomer. The specific material used for the elastic connector 310 is not limited, as long as the material has sufficient elasticity and high temperature resistance to meet the deformation absorption function. In the present invention, the elastic connector 310 is preferably made of silicone. Silicone has a buffering effect and can effectively absorb deformation of the magnetic valve 100 and the control assembly 200. It can also effectively block the intrusion of moisture, preventing damage to components within the magnetic valve assembly due to moisture, thereby improving the reliability and stability of the magnetic valve assembly.

[0041] In some embodiments of the present invention, Figure 2 As shown, the floating assembly 300 includes a sealing cover 320, which is sleeved around the periphery of the control assembly 200 and abuts the bottom of the control assembly 200. A transverse buffer structure is provided between the sealing cover 320 and the outer wall of the control assembly 200. It should be noted that after the sealing cover 320 is assembled with the elastic connector 310, the elastic connector 310 can absorb longitudinal deformation of the control assembly 200, while the transverse buffer structure can absorb transverse deformation of the control assembly 200 and the magnetic valve 100, thereby achieving multi-directional deformation absorption of the control assembly 200 and the magnetic valve 100 and improving the reliability of the magnetic valve assembly. Optionally, the transverse buffer structure is a gap between the sealing cover 320 and the outer wall of the control assembly 200. The sealing cover 320 and the elastic connector 310 cooperate to form a buffer cavity. When the magnetic valve 100 or the control assembly 200 expands or contracts due to heat or cold, the buffer cavity can effectively absorb the deformation of the magnetic valve 100 and the control assembly 200. The sealing cover 320 can play a good waterproof and sealing role, effectively preventing the steam generated in the electric pressure cooker from entering the control component 200, avoiding the occurrence of problems such as the control component 200 getting damp or the control component 200 not working properly due to the humid environment in the electric pressure cooker, thereby improving the working stability of the control component 200.

[0042] In some embodiments of the present invention, referring to Figure 1 、 Figure 2 and Figure 5The sealing cover 320 includes a valve cover 3201 and a sealing bracket 3202. The valve cover 3201 is made of a material with magnetic conductivity, which can further enhance the magnetic field strength generated by the control component 200, thereby increasing the magnetic field force on the magnetic valve 100. The lateral buffer structure includes a first buffer cavity 340 and a second buffer cavity 350. The valve cover 3201 is sleeved on the control component 200 and forms a first buffer cavity 340 between the valve cover 3201 and the control component 200. The valve cover 3201 abuts the bottom of the control component 200 and there is a gap between the valve cover 3201 and the outer wall of the control component 200, that is, the first buffer cavity 340 is formed between the valve cover 3201 and the control component 200. When the control component 200 is deformed by thermal expansion and contraction, the first buffer cavity 340 can effectively absorb the deformation of the control component 200. The sealing bracket 3202 is mounted on the valve housing 3201, forming a second buffer chamber 350 between the sealing bracket 3202 and the outer wall of the valve housing 3201. This means that a gap exists between the sealing bracket 3202 and the outer wall of the valve housing 3201, with the bottom of the sealing bracket 3202 abutting the valve housing 3201. The sealing bracket 3202 protects the valve housing 3201 and the control assembly 200, while the second buffer chamber 350 acts as a dual buffer, absorbing deformation of the valve housing 3201. When the solenoid valve 100 assembly is operating, the internal components of the sealing bracket 3202 expand and contract due to heat and cold. The presence of the second buffer chamber 350 effectively prevents damage to the outermost sealing bracket 3202 caused by deformation of these components, effectively preventing the intrusion of external moisture and ensuring the reliability of the magnetic valve assembly.

[0043] In some embodiments of the present invention, referring to Figure 1 and 2 The floating assembly 300 includes an iron core 330. The iron core 330, the control assembly 200 and the sealing cover 320 are all annular structures. A hollow cavity is provided in the middle of the iron core 330. The magnetic valve 100 is connected to the control assembly 200 and the floating assembly 300 through the hollow cavity. The control assembly 200 is located between the iron core 330 and the sealing cover 320. The elastic connector 310 is provided with an annular groove, which is provided on the end face of the elastic connector 310. A corresponding limit portion is provided at one end of the iron core 330. One end of the iron core 330 is connected to the inner side of the elastic connector 310, and the sealing cover 320 is connected to the outer side of the elastic connector 310. In the combined structure of the elastic connector 310 and the iron core 330, the inner side of the elastic connector 310 refers to the side facing the center of the iron core 330 and the peripheral part connected thereto. The outer side of the elastic connector 310 is opposite to the inner side, and refers to the side facing away from the iron core 330 and its peripheral part. The other end of the iron core 330 is closed and connected to the sealing cover 320. The closed connection method is active riveting. The riveting can form a tight fit between the iron core 330 and the sealing cover 320, and can effectively resist the relative displacement under the action of external force, making the connection part very firm and able to withstand large loads, ensuring that the floating component 300 and the control component 200 remain stable during long-term use.

[0044] Further, in some embodiments of the present invention, referring to Figure 1 、 Figure 4 and Figure 5 The magnetic valve 100 includes an exhaust valve core 110 and a magnetic valve cap 120 movably connected to the end of the exhaust valve core 110. The exhaust valve core 110 is provided with a steam channel, and the magnetic valve cap 120 is movably connected to the steam channel. A hollow cavity is provided in the middle of the iron core 330, and the exhaust valve core 110 is installed on the iron core 330. If the exhaust valve core 110 passes through the hollow cavity of the iron core 330, the magnetic valve cap 120 cooperates with the control component 200 to control the sealing and exhaust of the exhaust valve core 110. In some applications, the exhaust valve core 110 has a first state and a second state. When the exhaust valve core 110 is in the first state, the magnetic valve cap 120 is pressed against the steam channel by its own gravity or the magnetic field force of the control component 200, and the exhaust valve core 110 is sealed, thereby ensuring that the pressure in the pot can steadily rise, so that food can be cooked in a suitable high-pressure environment; when the exhaust valve core 110 is in the second state, the magnetic valve cap 120 is acted upon by the magnetic field repulsion force of the control component 200, driving the magnetic valve cap 120 to move away from the steam channel, the steam channel is opened, the exhaust valve core 110 is exhausted, and when cooking is completed or the pressure in the pot reaches the set safety upper limit and needs to be released, the pressure in the pot can be quickly reduced by exhausting.

[0045] In a further embodiment of the present invention, referring to Figure 1 、 Figure 3 and Figure 5The control component 200 includes an inductor component 210 and a packaging cover 220. The packaging cover 220 is mounted on the periphery of the inductor component 210 and packages the inductor component 210. The packaging cover 220 is used to protect the inductor component 210 to prevent the inductor component 210 from being affected by external factors such as water vapor or dust impurities and unable to work normally, thereby improving the working stability of the inductor component 210 and extending its service life. The inner side wall of the elastic connector 310 is provided with a mounting groove 3101, and the packaging cover 220 is provided with a first mounting portion 2201. The outer dimensions of the mounting groove 3101 correspond to those of the first mounting portion 2201, and the first mounting portion 2201 is embedded and installed in the mounting groove 3101. On the one hand, the embedded installation method enables the packaging cover 220 to achieve a stable connection with the elastic connector 310. The elastic connector 310 moves due to the deformation of the control component 200, and the packaging cover 220 can move together with the elastic connector 310. On the other hand, the packaging cover 220 and the elastic connector 310 are interference fit. When the control component 200 and the magnetic valve 100 are deformed, the elastic connector 310 can absorb these deformations through its own elasticity. The embedded installation connection method ensures that the packaging cover 220 and the elastic connector 310 will not easily undergo relative displacement or loosening during the operation of the magnetic valve assembly, thereby ensuring the integrity and stability of the entire device structure.

[0046] In some embodiments of the present invention, reference Figure 1 、 Figure 3 and Figure 5 The inductor component 210 includes a fixed bracket 2101 and an inductor coil 2102. An annular groove is defined in the middle of the outer wall of the fixed bracket 2101. The inductor coil 2102 is sleeved around the fixed bracket 2101 and wound within the annular groove. It is understood that the inductor coil 2102 exhibits electromagnetic induction properties. When current passes through the inductor coil 2102, it generates a magnetic field around it, thereby controlling the magnetic valve 100. The outer periphery of the fixing bracket 2101 protrudes beyond the outer periphery of the inductor coil 2102, facilitating the encapsulation of the inductor component 210 by the encapsulation cover 220. The fixing bracket 2101 is provided with a second mounting portion 21011, which extends into the mounting groove 3101 and abuts against the groove wall of the mounting groove 3101. The second mounting portion 21011 is annular, with its inner sidewall abutting against the groove wall of the mounting groove 3101 and its outer sidewall abutting against the first mounting portion 2201 of the encapsulation cover 220. The first mounting portion 2201, the second mounting portion 21011, and the mounting groove 3101 cooperate to form a stable connection structure. Furthermore, when the control assembly 200 deforms due to thermal expansion and contraction, the elastic connector 310 can more efficiently absorb the deformation of the control assembly 200.

[0047] In a further embodiment of the present invention, referring to Figure 1 and Figure 3 The packaging cover 220 is provided with a wire outlet 2202 for connecting to external wires. The wire outlet 2202 is disposed within the float assembly 300 and forms an elastic seal therebetween. For example, the elastic seal may be made of silicone. This elastic seal provides a buffer between the wire outlet 2202 and the float assembly 300 and effectively prevents external impurities such as moisture and dust from entering the device through the gap between the wire outlet 2202 and the float assembly 300. This ensures the stability and reliability of the wire connection and the stable operation of the inductor component 210. In other embodiments, the wire outlet 2202 and the float assembly 300 are sealed with glue.

[0048] like Figure 6 As shown, the cooking appliance 500 according to the embodiment of the second aspect of the present invention includes the magnetic valve assembly according to the embodiment of the present invention.

[0049] According to the cooking appliance 500 of the embodiment of the present invention, by adopting the magnetic valve assembly of the embodiment of the present invention, when the cooking appliance 500 is in use or under the influence of ambient temperature, the magnetic valve 100 and the control component 200 will expand and contract due to temperature factors. Due to the presence of the elastic connecting member 310, the deformation of the control component 200 and the magnetic valve 100 under the influence of thermal expansion and contraction can be absorbed, and the floating component 300 can be prevented from being cracked due to stress, thereby improving the reliability of the magnetic valve assembly, thereby improving the stability of the cooking appliance 500 and extending the service life of the cooking appliance 500.

[0050] Other structures and operations of the cooking appliance 500 according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
