Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] Existing food processors capable of making soy milk typically have a pressure relief vent in the lid. This vent maintains pressure balance between the inside and outside of the cup during the high-speed rotation of the grinding blades and the high-temperature cooking process. Therefore, existing soy milk makers, food processors, and other similar machines lack a high-pressure cooking function, resulting in a less smooth soy milk texture. Furthermore, even with increased grinding speed or cooking time to improve fineness, the average particle size rarely increases beyond 100-120µm, leaving a grainy texture when consumed.

[0003] Patent CN219782248U discloses a pot lid and a food processor. The pot lid includes a lid body, a locking assembly, and a float assembly. The locking assembly includes a push plate bracket and a locking push plate. The push plate bracket has an upper limit hole and a lower limit hole. The locking push plate can move laterally on the push plate bracket. The float assembly includes an upper float on the locking push plate and a lower float on the lid body. The float assembly can adjust according to the pressure changes inside the pot. When the pressure inside the pot is higher than a preset value, the top and bottom of the upper float will extend into the upper limit hole and the lower limit hole respectively to restrict the lateral movement of the locking push plate, avoid the risk of forcibly opening the lid, and achieve a simmering effect.

[0004] However, if the pressure continues to rise during the cooking process, a pressure relief device needs to be installed independently in other locations on the pot body or lid. The pressure relief device and the float assembly are installed independently, which makes the structure complex and inconvenient to install. In addition, there are many openings, which can lead to pressure leakage and instability during the pressure holding stage of the cooking process. Utility Model Content

[0005] This utility model provides a food processing machine that expands the function of cooking soy milk on the basis of existing food processing machines, solves the problem of soy milk not having a smooth texture, and also solves the problem of complex structure and inconvenient installation caused by the need to arrange the float valve and pressure relief valve independently in the existing technology.

[0006] The technical solution adopted in this utility model is as follows:

[0007] This utility model provides a food processing machine, including a cup body and a cup lid that enclose a sealed pulping chamber. A pulverizing device is installed inside the pulping chamber. The cup lid includes an inner lid with an installation hole, an outer lid, a float valve that can be lifted and lowered within the installation hole, and a push plate installed between the inner and outer lids. The push plate has a locking pin. The float valve cooperates with the push plate to lock and unlock the cup lid relative to the cup body via the locking pin. The float valve includes a valve body and a sealing ring that seals the valve body to the installation hole. A pressure relief valve communicating with the outside is provided inside the valve body. The valve body has a pressure relief hole on its bottom wall that connects the pulping chamber to the pressure relief channel. The float valve also includes a pressure relief valve movably disposed in the pressure relief channel. The pressure relief valve is pressed against the bottom wall of the valve body to seal the pressure relief hole. The float valve has a first state and a second state. In the first state, the valve body rises to lock the push plate, thereby locking the cup lid relative to the cup body, and the pressure relief valve seals the pressure relief hole. In the second state, the valve body remains locked to the push plate, and the pressure relief valve moves relative to the valve body to open the pressure relief hole.

[0008] The food processor provided by this utility model achieves structural integration by incorporating a float valve in the cup lid and integrating a pressure relief valve into the float valve. This simplifies the overall structure and the installation process of the float valve and pressure relief valve. When the cup lid of a food processor for making soy milk is relatively small, the placement of the float valve eliminates the need for additional space on the lid for the pressure relief valve, resulting in a compact lid structure and fewer openings. This ensures stable pressure during the high-pressure cooking stage, preventing pressure leakage and ensuring structural reliability. Furthermore, the float valve and pressure relief valve change state according to pressure variations within the cup, expanding the high-pressure cooking function of the food processor and preventing safety hazards caused by excessive pressure. The float valve has a first state and a second state. In the first state, the pressure inside the cup reaches a first preset value, and the valve body rises to lock the push plate, locking the cup lid relative to the cup body. The pressure relief valve seals the pressure relief hole, thereby realizing the high-pressure cooking function of the cup. The high pressure in the cup body promotes water molecules to penetrate into the soybeans more quickly, increasing the water absorption rate of soybeans and further softening the cell walls of soybeans. Accompanied by the crushing device, the cell walls of soybeans are fully broken, thereby reducing soybean residue and making the slurry delicate and smooth, achieving the taste of soy milk and reducing the grainy feeling when drinking it. The soy milk boils under high pressure, fully cooking and promoting the release and fusion of flavor substances, making the soy milk more flavorful. Moreover, the push plate is locked in the first state to prevent the user from opening the lid, improving operational safety. In the second state, the pressure inside the cup increases further, reaching a second preset value higher than the first preset value. The valve body remains locked to the push plate, and the pressure relief valve moves relative to the valve body to open the pressure relief hole, thereby connecting the pulping chamber with the outside world. This causes the air pressure inside the cup to drop rapidly, avoiding safety issues such as the cup lid bulging and pulp overflow caused by the high air pressure inside the pulping chamber. It also reduces the user's waiting time to open the lid, improves safety, and enhances ease of operation.

[0009] In a preferred embodiment, the pressure relief valve includes a spring and a valve core. The valve body has an abutment portion located above the valve core. One end of the spring, which is in a compressed state, abuts against the abutment portion, and the other end abuts against the valve core, so as to press the valve core tightly to seal the pressure relief hole.

[0010] The pressure relief valve includes a spring and a valve core. The valve body has an abutment portion. One end of the spring, in a compressed state, abuts against the abutment portion, and the other end abuts against the valve core. The spring's preload seals the valve core at the pressure relief port, ensuring structural stability. When the pressure inside the cup exceeds the spring's preload, the valve core is pushed up, opening the pressure relief port and releasing the pressure inside the cup quickly, maintaining the cup pressure within a safe range. The spring and valve core are compact, allowing for flexible pressure adjustment within the cup. The pressure relief pressure can be flexibly adjusted by changing the spring's preload, providing flexible and accurate control. When the pressure inside the cup drops to a first preset value, the valve core can be reset by the spring to seal the pressure relief port.

[0011] In a preferred embodiment, the valve body includes a lower valve sleeve and an upper valve sleeve. The lower valve sleeve has a bottom wall for providing the pressure relief hole. The valve core is accommodated in the lower valve sleeve. The bottom end of the upper valve sleeve is inserted and fixed in the lower valve sleeve. The abutting portion is the bottom end face of the upper valve sleeve.

[0012] By configuring the valve body into separate lower and upper valve sleeves, the valve core can be easily installed in the lower valve sleeve. The bottom end of the upper valve sleeve is inserted and fixed in the lower valve sleeve to limit the installation of the valve core. At the same time, the abutting part is the bottom end face of the upper valve sleeve that abuts against the spring, so that the valve core and the pressure relief hole are tightly fitted and the pressure relief hole is sealed.

[0013] In a preferred embodiment, the valve core includes a body and an elastic sealing head fixed to the bottom of the body, the spring abutting against the body, and the elastic sealing head sealing the pressure relief hole.

[0014] By using an elastic sealing head, such as silicone or fluororubber, a flexible dynamic sealing surface can be formed under the action of spring preload, thanks to the elastic deformation capability of the sealing head. This avoids the problem of unreliable sealing caused by unevenness of the bottom wall of the valve body due to processing errors. After the cup body is depressurized to the first preset value, the elastic sealing head can quickly reset to seal the pressure relief hole.

[0015] In a preferred embodiment, the valve body includes a valve body and a locking body separately disposed above the valve body. The float valve also has a third state in which the locking body is unlocked relative to the push plate, and the valve body is in a state separated from the locking body. In the first state, the locking body is pushed by the rising valve body to lock the push plate.

[0016] By setting the valve body as a separate valve body and locking body, in the third state, the locking body is unlocked relative to the push plate, and the valve body is in a state separated from the locking body. That is, there is a buffer gap between the valve body and the locking body. The locking body is pushed to move synchronously after the valve body moves upward by the distance of the buffer gap, so as to switch to the first state. This reduces the movement stroke of the locking body between the third state and the first state, reduces the resistance to the upward movement of the valve body, and makes the state switching of the float valve smooth and flexible.

[0017] In a preferred embodiment, the float valve further includes a valve housing fixed to the mounting hole, the valve housing having a first channel for accommodating the valve body and a second channel for accommodating the locking body, a step being provided between the first channel and the second channel, and in a third state, the locking body being supported by the step.

[0018] By configuring a valve shell, which is fixed to the mounting hole, the valve body can be stably installed on the cup lid. The valve shell has a first channel and a second channel, which guide the movement of the valve body and the locking body, respectively, ensuring smooth movement without jamming and smooth pressure relief. By setting a step between the first and second channels, in the third state, the locking body is supported by the step, allowing it to separate from the valve body. This makes the state switching of the float valve smooth and flexible, while the step structure is simple, simplifying the internal structure of the float valve.

[0019] In a preferred embodiment, the pressure relief channel includes an exhaust channel disposed in the valve body and communicating with the pulping chamber, and a connecting channel passing through the locking body. The outer cover has an exhaust port, and the exhaust channel, the connecting channel, and the exhaust port are connected.

[0020] By opening an exhaust port on the outer cover, which includes an exhaust channel and a connecting channel, the exhaust channel, the connecting channel, and the exhaust port are connected. The pressure relief channel is straight, the pressure relief is smooth, and the cup body can be quickly depressurized.

[0021] In a preferred embodiment, the float valve further includes a valve housing, the valve body being fitted onto the valve housing, the valve housing including a shell and a flange that expands radially relative to the shell, the shell being locked through a mounting hole by a nut and the flange being pressed against the edge of the mounting hole, the inner edge of the sealing ring being fixedly connected to the valve body, and the outer edge of the sealing ring extending to be clamped by the flange and the edge of the mounting hole.

[0022] The valve body includes a housing and a flange. The flange is used to limit the movement of the valve body by means of the edge of the mounting hole. The upper end of the housing is locked with a nut to achieve reliable fixation of the valve body. The inner edge of the sealing ring is fixed to the valve body, and the outer edge extends to be clamped by the flange and the edge of the mounting hole. The clamping of the flange and the mounting hole achieves reliable installation and sealing connection of the valve body. At the same time, the shape of the sealing ring can flexibly deform when the pressure inside the cup changes, and the valve body floats, thereby locking the cup lid and regulating the air pressure inside the cup.

[0023] In a preferred embodiment, the push plate is provided with a locking hole, the outer cover is provided with a guide groove corresponding to the upper part of the valve body, the upper part of the valve body includes a guide part that cooperates with the guide groove, a locking part that locks with the locking hole, and a contraction part connected between the guide part and the locking part, the contraction part being unlocked with the locking hole.

[0024] By providing a guide groove on the outer cover corresponding to the valve body, and a guide part on the upper part of the valve body, the valve body can reliably move up and down along the guide groove, avoiding deviation, thereby achieving sensitive adjustment of the gas pressure inside the cup, with rapid response and reset, and accurate adjustment. By providing a locking part that engages with the locking hole, and a contraction part connecting the guide part and the locking part, the contraction part engages with the locking hole. When the gas pressure inside the cup reaches a first preset value, the locking part of the valve body limits the locking hole of the push plate, locking the push plate and preventing the user from opening the cup, ensuring safety. Simultaneously, after the gas pressure inside the cup drops, the valve body returns to its original position, and the contraction part moves to engage with the locking hole, releasing the lock on the push plate, allowing the user to open the cup.

[0025] In a preferred embodiment, the pressure relief valve includes a silicone plug and a bellows integrally connected above the silicone plug. The valve body is provided with an abutment portion located above the silicone plug, and the upper end of the bellows abuts against the abutment portion.

[0026] The pressure relief valve is designed with a silicone plug and a bellows integrally connected above the silicone plug, which further simplifies the valve structure. Moreover, the pressure relief valve can maintain its integral movement for a longer period of time, allowing for flexible adjustment based on the pressure inside the cup and achieving rapid pressure relief.

[0042] like Figure 1-8 As shown, in a preferred embodiment, this utility model provides a food processing machine, such as... Figure 1 As shown, the food processing machine includes a cup body 10 and a cup lid 20 that enclose a sealed pulping chamber. A pulverizing device 30 is installed inside the pulping chamber. The pulverizing device 30 is a pulverizing blade, or it may include a moving grinding head and a stationary grinding head. The food processing machine also includes a motor 70 for driving the pulverizing device 30 and a heating tube 80 for heating the cup body 10. The cup lid 20 includes an inner lid 22 with an installation hole, an outer lid 21, a float valve 50 that can be lifted and lowered within the installation hole, and a push plate 40 installed between the inner lid 22 and the outer lid 21. The push plate 40 is provided with a locking pin 41, and a corresponding pin hole is provided in the cup body 10 for the locking pin 41 to be inserted. The float valve 50 cooperates with the push plate 40 to lock and unlock the cup lid 20 relative to the cup body 10 through the locking pin 41. Figure 2As shown, the float valve 50 includes a valve body 51 and a sealing ring 52 that seals the valve body 51 to the mounting hole. The valve body 51 is provided with a pressure relief channel 514 that communicates with the outside. The bottom wall of the valve body 51 is provided with a pressure relief hole 513 that communicates the pulping chamber with the pressure relief channel 514. The float valve 50 also includes a pressure relief valve 53 that is movably disposed in the pressure relief channel 514. The pressure relief valve 53 is pressed against the bottom wall of the valve body 51 to seal the pressure relief hole 513.

[0043] In this embodiment, the float valve 50 has a first state, a second state, and a third state:

[0044] like Figure 1 , Figure 2 As shown, in the third state, the air pressure inside the cup body 10 does not reach the first preset value, and the valve body 51 is in the normal position.

[0045] like Figure 3 As shown, in the first state, as the air pressure inside the cup body 10 increases, when the air pressure inside the cup body 10 reaches the first preset value, the valve body 51 floats upward to lock the push plate 40, so that the cup lid 20 is locked relative to the cup body 10, and the pressure relief valve 53 seals the pressure relief hole 513.

[0046] like Figure 4 As shown, in the second state, as the air pressure inside the cup 10 increases, when the air pressure inside the cup 10 reaches a second preset value higher than the first preset value, the valve body 51 remains locked to the push plate 40, and the pressure relief valve 53 moves relative to the valve body 51 to open the pressure relief hole 513.

[0047] This invention provides a food processor that integrates a float valve 50 into the cup lid 20, and simultaneously integrates a pressure relief valve 53 into the float valve 50, achieving structural integration, simplifying the overall machine structure, and simplifying the installation process of the float valve and pressure relief valve. When the cup lid of a food processor for preparing soy milk is relatively small, the placement of the float valve 50 eliminates the need for additional space on the cup lid for the pressure relief valve 53, resulting in a compact cup lid structure and reducing the number of openings in the cup lid 20. This ensures stable pressure during the high-pressure cooking stage of the food processor, preventing pressure leakage and ensuring structural reliability. Furthermore, the float valve 50 and pressure relief valve 53 change state according to the pressure changes within the cup body 10, not only expanding the high-pressure cooking function of the food processor but also utilizing the pressure relief valve 53 to prevent safety hazards caused by excessive pressure within the cup. In the first state, the pressure inside the cup body 10 reaches the first preset value. The valve body 51 rises to lock the push plate 40, locking the cup lid 20 relative to the cup body 10. The pressure relief valve 53 seals the pressure relief hole 513, thus realizing the high-pressure cooking function of the cup body 10. The high pressure of the cup body 10 further softens the cell walls of the soybeans. Accompanied by the crushing of the crushing device 30, the cell walls of the soybeans are fully broken, thereby reducing soybean residue and making the soy milk smooth and delicate, achieving the taste of soy milk. This reduces the grainy feeling when drinking the soy milk, and the average particle size of the soy milk decreases to 80um. Moreover, the temperature of the pressure-cooked soy milk exceeds the boiling point of 100℃, resulting in more thorough cooking. Proteins and fats are fully decomposed, releasing free amino acids, peptides, and fatty acids, making the nutrients easier to absorb. The hydrogen bonds between soybean fiber molecules are broken, causing the cellulose network structure to become loose. Boiling under high pressure promotes the release and fusion of flavor substances, producing fatty acids and esters, making the flavor of the soy milk richer. High pressure fully hydrolyzes proteins, fats, and starches, releasing aroma and sweetness, thus enhancing the rich and mellow taste of the soy milk. In the first state, the push plate 40 is locked to prevent the user from opening the lid, improving operational safety. In the second state, the pressure inside the cup body 10 further increases, reaching a second preset value higher than the first preset value. The valve body 51 remains locked to the push plate 40, and the pressure relief valve 53 moves relative to the valve body 51 to open the pressure relief hole 513, thereby connecting the pulping chamber with the outside. This allows the air pressure inside the cup body 10 to drop rapidly, preventing safety issues such as explosions caused by high air pressure in the pulping chamber. It also reduces the user's waiting time to open the lid, improving safety and ease of operation.

[0048] This utility model does not limit the specific structure of the valve body, for example, such as Figure 1-4 As shown, the valve body 51 includes a valve body 511 and a locking body 512 separately disposed above the valve body 511.

[0049] Of course, in another preferred embodiment, the valve body 51 includes a valve body 511 and a locking body 512 integrally connected to the valve body, wherein the locking body 512 is locked in place with the locking hole of the push plate.

[0050] Preferably, the pressure relief channel 514 includes an exhaust channel disposed on the valve body 511 and communicating with the pulping chamber, and a connecting channel that passes through the locking body 512. The outer cover 21 has an exhaust port 211, and the exhaust channel, the connecting channel, and the exhaust port 211 are connected.

[0051] By including an exhaust channel and a connecting channel in the pressure relief channel 514, and opening an exhaust port in the outer cover 21, the exhaust channel, the connecting channel, and the exhaust port are connected, the pressure relief channel 514 is straight, the pressure relief is smooth, and the cup body 10 is quickly depressurized.

[0052] In other embodiments, the pressure relief passage 514 may also communicate with the outside through a gap formed between the pressure relief valve and the valve body.

[0053] like Figure 2 As shown, in a preferred embodiment, the pressure relief valve 53 includes a spring 531 and a valve core 532. The valve body 51 is provided with an abutment portion 510 located above the valve core 532. One end of the spring 531 in the compressed state abuts against the abutment portion 510, and the other end abuts against the valve core 532, so as to press the valve core 532 tightly to seal the pressure relief hole 513.

[0054] As a preferred option, such as Figure 5 As shown, the valve body 51 includes a lower valve sleeve 5111 and an upper valve sleeve 5112. The lower valve sleeve 5111 has a bottom wall with a pressure relief hole 513. The valve core 532 is accommodated in the lower valve sleeve 5111. The bottom end of the upper valve sleeve 5112 is inserted and fixed in the lower valve sleeve 5111, for example, by thread. The abutment portion 510 is the bottom end face of the upper valve sleeve 5112. In this embodiment, the locking body 512 can be integrally formed on the upper valve sleeve 5112; of course, the locking body 512, the lower valve sleeve 5111, and the upper valve sleeve 5112 can also be separately provided.

[0055] By setting the valve body 51 as a separate lower valve sleeve 5111 and upper valve sleeve 5112, the valve core 532 can be easily installed in the lower valve sleeve 5111. The bottom end of the upper valve sleeve 5112 is inserted and fixed in the lower valve sleeve 5111, thereby limiting the installation of the valve core 532. At the same time, the abutting part 510 is the bottom end face of the upper valve sleeve 5112, which abuts against the spring 531, so that the valve core 532 and the pressure relief hole 513 are tightly fitted and the pressure relief hole 513 is sealed.

[0056] The pressure relief valve 53 includes a spring 531 and a valve core 532. The valve body 51 has an abutment portion 510. One end of the spring 531, in a compressed state, abuts against the abutment portion 510, and the other end abuts against the valve core 532. The preload of the spring 531 seals the valve core 532 at the pressure relief hole 513, ensuring structural stability. When the pressure inside the cup 10 exceeds the preload of the spring 531, the valve core 532 is pushed up, opening the pressure relief hole 513, releasing the pressure inside the cup, quickly relieving pressure, and maintaining the pressure inside the cup 10 within a safe range. The spring 531 and valve core 532 are compact, allowing for flexible pressure adjustment of the cup 10. The pressure relief pressure can be flexibly adjusted by adjusting the preload of the spring 531, providing flexible and accurate control. When the pressure inside the cup 10 drops to a first preset value, the valve core 532 can be reset by the spring 531 to seal the pressure relief hole 513.

[0057] Of course, in another preferred embodiment, the pressure relief valve 53 includes a silicone plug and a bellows integrally connected above the silicone plug, and the valve body 51 is provided with an abutment portion 510 located above the silicone plug, and the upper end of the bellows abuts against the abutment portion 510.

[0058] The pressure relief valve 53 is configured as a silicone plug and a bellows integrally connected above the silicone plug, which further simplifies the structure of the pressure relief valve 53. Moreover, the pressure relief valve 53 can maintain integral movement for a longer period of time, so as to flexibly adjust according to the pressure inside the cup 10 and achieve rapid pressure relief.

[0059] like Figure 5 As shown, in a preferred embodiment, the valve core 532 includes a body 5321 and an elastic sealing head 5322 fixed to the bottom of the body 5321. The spring 531 abuts against the body 5321, and the elastic sealing head 5322 blocks the pressure relief hole 513.

[0060] By using an elastic sealing head 5322, such as silicone or fluororubber, a flexible dynamic sealing surface can be formed under the pre-tightening force of the spring 531 by utilizing the elastic deformation capability of the sealing head. This can avoid the problem of unreliable sealing caused by unevenness of the bottom wall of the valve body 51 due to processing errors. After the cup body 10 is depressurized to the first preset value, the elastic sealing head can quickly reset to seal the pressure relief hole 513.

[0061] like Figure 1 , 2 As shown, in a preferred embodiment, the valve body 51 includes a valve body 511 and a locking body 512 separately disposed above the valve body 511. The float valve 50 also has a third state in which the locking body 512 is unlocked relative to the push plate 40, and the valve body 511 is in a state of separation from the locking body 512. In the first state, the locking body 512 is pushed by the rising valve body 511 to lock against the push plate 40.

[0062] Optionally, such as Figure 2 As shown, the float valve 50 also includes a valve housing 54 fixed to the mounting hole. The valve housing 54 has a first channel for accommodating the valve body 511 and a second channel for accommodating the locking body 512. A step 515 is provided between the first channel and the second channel. In the third state, the locking body 512 is supported by the step 515.

[0063] By setting the valve body 51 as a separate valve body 511 and locking body 512, in the third state, the locking body 512 is unlocked relative to the push plate 40, and the valve body 511 is in a state separated from the locking body 512. That is, there is a buffer gap between the valve body 511 and the locking body 512. The locking body 512 is pushed to move synchronously after the valve body 511 moves upward by the distance of the buffer gap, so as to switch to the first state. This reduces the movement stroke of the locking body 512 between the third state and the first state, reduces the resistance of the valve body 511 moving upward, and makes the state switching of the float valve 50 smooth and flexible.

[0064] By setting a valve housing 54, which is fixed to the mounting hole, the valve body 51 can be stably installed on the cup cover 20 through the valve housing 54. The valve housing 54 is provided with a first channel and a second channel, which respectively guide the movement of the valve body 511 and the locking body 512, ensuring smooth movement without jamming and smooth pressure relief. By setting a step between the first channel and the second channel, in the third state, the locking body 512 is supported by the step, allowing it to separate from the valve body 511. The state switching of the float valve 50 is smooth and flexible, and the step structure is simple, simplifying the internal structure of the float valve 50.

[0065] Of course, in addition to using the step-supported locking body 512 described above, in other preferred embodiments, an extension post extending downward can be provided on the outer cover, and a support flange can be provided on the outer periphery of the extension post. In the third state, the locking body 512 is supported by the support flange.

[0066] Alternatively, a dragging step can be provided in the inner cover at the mounting hole, and the locking body 512 can be dragged by the dragging step.

[0067] like Figure 6 As shown, in a preferred embodiment, the float valve 50 further includes a valve housing 54, with the valve body 51 inserted into the valve housing 54. The valve housing 54 includes a housing 541 and a flange 542 that expands radially relative to the housing 541. The housing 541 passes through a mounting hole and is locked by a nut 60, with the flange 542 pressed against the edge of the mounting hole. A gasket 61 is clamped between the nut and the upper wall of the inner cover 21. Figure 2 The inner edge of the sealing ring 52 is fixedly connected to the valve body 51, and the outer edge of the sealing ring 52 extends to be held by the flange 542 and the edge of the mounting hole.

[0068] The valve housing 54 includes a housing 541 and a flange 542. The flange 542 is used to limit the movement of the valve housing 541 by means of a nut 60 to lock the upper end of the housing 541 to achieve reliable fixation of the valve housing 54. The inner edge of the sealing ring 52 is fixed to the valve body 51, and the outer edge extends to be clamped by the flange 542 and the edge of the mounting hole. The clamping of the flange 542 and the mounting hole achieves reliable installation and sealing connection of the valve body 51. At the same time, the shape of the sealing ring 52 can flexibly deform when the pressure inside the cup 10 changes, and the valve body 51 floats, thereby locking the cup lid 20 and regulating the air pressure inside the cup.

[0069] In addition to the above-mentioned structure, the float valve can also be installed by interfering with the valve body 54 in the mounting hole.

[0070] This invention does not limit the locking method between the valve body and the push plate. In a preferred embodiment, such as... Figure 7 , 8 As shown, the push plate 40 extends to correspond to the valve body 51 and has a through-hole 42. The outer cover 21 has a guide groove corresponding to the upper part of the valve body 51. The upper part of the valve body 51 includes a guide part 516 that cooperates with the guide groove, a locking part 518 that locks with the lock hole, and a contraction part 517 that connects the guide part and the locking part. The contraction part 517 unlocks with the lock hole 42.

[0071] By providing a guide groove on the outer cover 21 corresponding to the upper part of the valve body 51, and a guide part on the upper part of the valve body 51, the valve body 51 can reliably move up and down along the guide groove, avoiding deviation, thereby achieving sensitive adjustment of the gas pressure inside the cup, with rapid response and reset, and accurate adjustment. By providing a locking part that engages with the lock hole, and a contraction part connecting the guide part and the locking part, the contraction part engages with the lock hole for unlocking. When the gas pressure inside the cup reaches the first preset value, the locking part 518 of the valve body 51 limits the locking hole 42 of the push plate 40, such as... Figure 7 As shown, the push plate 40 is locked to prevent the user from opening the lid, ensuring safety. Simultaneously, after the pressure inside the cup decreases, the valve body 51 returns to its original position, and the contraction part 517 movably engages with the locking hole 42. Figure 8 As shown, the lock on the push plate 40 is released, allowing the user to open the cover.

[0072] More specifically, such as Figure 1 , 5 As shown, a horizontally arranged pressure spring 43 abuts between the push plate and the outer cover. When the push plate is unlocked, it can move horizontally. The user rotates the cup lid, and the outer peripheral wall of the cup body presses against the locking pin to overcome the elastic force of the pressure spring, so that the locking pin exits the locking hole of the cup body to open the cup lid.
