Description

Technical Field

[0001] The present application relates to the field of smart home technology, and in particular to an intelligent pressure-controlled pressure cooker. Background Art

[0002] A pressure cooker, also known as a pressure cooker, is a cooking pot that uses the physical phenomenon that the boiling point of liquid increases under high pressure to increase the efficiency of cooking food by applying pressure to water so that the water can reach a higher temperature without boiling. In actual applications, as the water in the pressure cooker gradually turns into gas, the pressure in the pressure cooker will gradually increase. In order to avoid over-pressure explosion, the pressure cooker is equipped with a safety valve.

[0003] The safety valve is usually set on the lid of the pressure cooker and is a pressure safety valve. When the air pressure in the pot exceeds the upper pressure limit, the safety valve automatically opens to release part of the gas in the pot and reduce the air pressure in the pot. The pressure cooker is usually also provided with an exhaust valve, which is used to manually open the exhaust valve after cooking to release the gas in the pot so that the air pressure inside and outside the pot remains constant. Avoid over-pressure explosion or scalding the user at the moment of opening the pressure cooker. It can be seen that the existing pressure cooker needs to be equipped with a safety valve and an exhaust valve on the lid at the same time, which reduces the reliability of the cooker, and it is easy to scald the user when releasing the gas after cooking. Summary of the invention

[0004] The present application provides an intelligent pressure-controlled pressure cooker to solve the problem that traditional pressure cookers have low reliability and are prone to scalding users.

[0005] The intelligent pressure-controlled pressure cooker provided in the present application comprises a cooker body and a cooker cover, wherein the cooker cover is provided with a safety valve, a linkage mechanism connected to the safety valve is provided inside the cooker cover, and an electromagnetic attraction mechanism is provided on the side wall of the cooker body;

[0006] The safety valve comprises a valve body shell; a vent hole is provided at the top of the valve body shell, and a step pipe is provided at the bottom of the valve body shell; a return spring, a vent gas and a pressure relief body are provided in sequence from top to bottom inside the valve body shell; a first vent hole is provided inside the vent gas, and a second vent hole is provided inside the pressure relief body; the vent gas can rotate relative to the pressure relief body so that the first vent hole and the second vent hole are interconnected or misaligned; a rotating part is provided on the side of the vent gas to drive the vent gas to rotate; one end of the return spring is connected to the top inner side surface of the valve body shell, and the other end contacts the vent gas; the bottom of the pressure relief body contacts the step pipe through the elastic force of the return spring; and when the air pressure inside the pot body exceeds a preset value, the pressure relief body is lifted up to discharge excess gas through the vent hole;

[0007] The linkage mechanism includes a transmission rod group and a magnetic float; one end of the transmission rod group is hinged to the rotating part, and the other end is connected to the magnetic float; the transmission rod group transmits the movement of the magnetic float to drive the gas release gas to rotate; the magnetic float is arranged on the edge of the pot cover, and after the pot cover is installed on the pot body, the magnetic float is located directly above the electromagnetic attraction mechanism, so that the electromagnetic attraction mechanism drives the magnetic float to move through magnetic attraction.

[0008] It can be seen from the above technical solutions that when the intelligent pressure-controlled pressure cooker provided by the present application is actually used, if the gas pressure generated in the pot body during cooking is higher than the preset value, the pressure relief body in the safety valve is lifted up, and a gap is formed between the pressure relief body and the valve body shell, so that the gas in the pot body is discharged from the pot body through the formed gap and the exhaust hole. When the gas pressure in the pot body is lower than the preset value, the pressure relief body is restored to its original position by the reset spring to maintain the high pressure in the pot body.

[0009] When the gas needs to be released after cooking, the electromagnetic attraction mechanism is started to generate magnetism, adsorb the magnetic float to form a movement, and transmit the formed movement to the gas release gas through the linkage mechanism, so that the gas release gas rotates, so that the first gas release hole in the gas release gas and the second gas release hole in the pressure relief body are connected to form a gas release channel, so as to release the gas in the pot body and reduce the air pressure in the pot body.

[0010] The present application can complete both pressure control and air release operations through a safety valve, avoids the need to set multiple valve bodies on the pot cover, improves the reliability of the pressure cooker, and releases gas in the pot body through electromagnetic adsorption, avoids manual opening of the air release valve, and reduces the chance of scalding.

[0017] See also Figure 1 , is a schematic diagram of the structure of an intelligent pressure-controlled pressure cooker in this application, comprising Figure 1 It can be seen that the intelligent pressure-controlled pressure cooker provided in the present application includes a pot body 1 and a pot cover 2. The pot body 1 and the pot cover 2 are used together, and the sizes of the pot body 1 and the pot cover 2 are adapted so that the pot cover 2 can be installed on the pot body 1 to maintain sufficient sealing.

[0018] Generally, the pot body 1 is a cylindrical structure, and the pot cover 2 is a disc-shaped structure adapted to the pot body 1. In actual application, the pot body 1 is used to hold food to be stewed. According to different heating principles of the pressure cooker, the pot body 1 should also have different structures. For example, when the pressure cooker is an electric pressure cooker, a heating liner and an outer shell can be provided in the pot body 1, and a corresponding electric heating device is provided in the outer shell, and the heating liner is used to hold food.

[0019] In the technical solution provided in the present application, the pot cover 2 is provided with a safety valve 3, the pot cover 2 is provided with a linkage mechanism 4 connected to the safety valve 3, and the side wall of the pot body 1 is provided with an electromagnetic attraction mechanism 5. In practical applications, in order not to affect the cooking process of the food in the pot body 1 and the action accuracy of the linkage mechanism 4, the pot cover 2 can have a double-layer structure. The safety valve 3 runs through the double-layer structure of the pot cover 2, and the linkage mechanism 4 is arranged between the outer layer and the inner layer of the pot cover 2. The action transmission is realized by the rod structure, and the linkage mechanism 4 can extend from the position of the safety valve 3 to the electromagnetic attraction mechanism 5. In the present application, the pot cover 2 with a double-layer structure can not only isolate the linkage mechanism 4 from the cooking space in the pot body 1, but also reduce the heat dissipation during the stewing process, so that the food can absorb more heat, thereby improving the stewing efficiency of the food. In addition, the double-layer structure can also reduce the temperature of the outer layer of the pot cover 2, so as to prevent the user from being scalded by the pot cover 2 when touching or opening the pot cover 2.

[0020] Furthermore, if Figure 1 As shown, the safety valve 3 is arranged at the center of the pot cover 2, and two linkage mechanisms 4 are symmetrically arranged on both sides of the safety valve 3. Correspondingly, two electromagnetic attraction mechanisms 5 are symmetrically arranged on the side wall of the pot body 1. On the one hand, the safety valve 3 is arranged at the center of the pot cover 2 to improve the overall aesthetics of the pot cover; on the other hand, the safety valve 3 is arranged at the center to facilitate the symmetrical arrangement of the linkage mechanisms 4 from two directions. The symmetrically arranged linkage mechanisms 4 can jointly initiate an action to rotate the gas release 34, thereby reducing the adsorption force requirements of the electromagnetic attraction mechanism 5 and reducing the suction force requirements of the electromagnetic attraction mechanism 5.

[0021] like Figure 2As shown, the safety valve 3 includes a valve body shell 31 located at the outermost side. The function of the valve body shell 31 is to facilitate the installation of the entire safety valve 3 on the pot cover 2. Since in actual application, the safety valve 3 is directly exposed to the cooking space, and there is a large amount of steam and a high temperature in the cooking space, in order to avoid scalding the user, the surface of the valve body shell 31 should be provided with a protective layer of non-metallic material (such as resin). An exhaust hole 311 is provided at the top of the valve body shell 31, and a step pipe 312 is provided at the bottom of the valve body shell 31. The exhaust holes 311 can be evenly distributed in the center of the safety valve 3 to form an exhaust channel for the pot.

[0022] The valve body shell 31 is provided with a return spring 33, a gas release gas 34 and a pressure relief body 35 in order from top to bottom. In practical applications, the return spring 33, the gas release gas 34 and the pressure relief body 35 are encapsulated inside the valve body shell 31, and only a hole for the linkage mechanism 4 to pass through is provided on the side of the valve body shell 31. The hole should ensure sealing performance while ensuring that the linkage mechanism 4 slides in the hole, that is, to prevent the gas from entering the gap between the valve body shell 31 and the gas release gas 34 and the pressure relief body 35, so as not to affect the action of the linkage mechanism 4.

[0023] A first air release hole 361 is provided inside the gas release body 34, and a second air release hole 362 is provided inside the pressure relief body 35; the gas release body 34 can rotate relative to the pressure relief body 35 so that the first air release hole 361 and the second air release hole 362 are connected to or misaligned with each other. In the present application, the gas release body 34 and the pressure relief body 35 can both be cylindrical structures, and there is a coaxial relationship between the gas release body 34 and the pressure relief body 35, so that the positions of the first air release hole 361 and the second air release hole 362 are more convenient to correspond to each other, forming a connected or misaligned relationship. Among them, the first air release hole 361 and the second air release hole 362 can be circular through holes or arc-shaped strip holes that penetrate the gas release body 34 and the pressure relief body 35 respectively. In order to improve the gas release efficiency, the number of the first air release hole 361 and the second air release hole 362 are both multiple, and the number is the same.

[0024] In practical applications, in the initial state or during the cooking process, such as Figure 4 As shown in FIG. 1 , the positions of the first air release hole 361 and the second air release hole 362 are staggered, and the gas in the pot body 1 will not enter the cavity inside the valve body shell 31 through the second air release hole 362, that is, no passage is formed. When the gas in the pot body 1 needs to be released, the air release hole 34 is rotated to make the positions of the first air release hole 361 and the second air release hole 362 coincide with each other, as shown in FIG. Figure 2 As shown, a gas passage is formed, and the gas in the pot body 1 enters the cavity inside the valve body shell 31 from the second air release hole 362 through the first air release hole 361, and is then released into the external environment through the exhaust hole 311.

[0025] In order to facilitate the rotation of the gas discharge 34, as Figure 3 As shown, a rotating part 37 is provided on the side of the exhaust gas 34 to drive the exhaust gas 34 to rotate. In practical applications, if the safety valve 3 is set at the center of the pot cover 2, and through two linkage mechanisms 4 and an electromagnetic attraction mechanism 5, the rotating part 37 can be two symmetrically arranged, respectively connected to the two linkage mechanisms 4, so as to rotate the exhaust gas 34 through the two linkage mechanisms 4, thereby reducing the driving force requirement; if the safety valve 3 is not set at the center of the pot cover 2, the safety valve 3 can be as close to the electromagnetic attraction mechanism 5 as possible to shorten the length of the linkage mechanism 4.

[0026] In some embodiments of the present application, the safety valve 3 further includes a valve body shaft 32, which is arranged inside the valve body shell 31, perpendicular to the top of the valve body shell 31, and penetrates the reset spring 33 and the venting gas 34, and the bottom of the valve body shaft 32 extends into the pressure relief body 35; the venting gas 34 and the pressure relief body 35 can slide along the valve body shaft 32. In this embodiment, the valve body shaft 32 is fixed inside the valve body shell 31, so that the venting gas 34 rotates around the valve body shaft 32.

[0027] Furthermore, the portion where the valve body shaft 32 contacts the gas release body 34 is a cylindrical structure, so that the gas release body 34 rotates with the valve body shaft 32 as the rotation axis; the portion where the valve body shaft 32 contacts the pressure relief body 35 is provided with a protrusion to prevent the pressure relief body 35 from rotating. In this embodiment, the protrusion can prevent the pressure relief body 35 from rotating with the gas release body 34 during the rotation of the gas release body 34, thereby facilitating the positions of the first gas release hole 361 and the second gas release hole 362 to be staggered with each other.

[0028] In the technical solution provided by the present application, one end of the return spring 33 is connected to the top inner side of the valve body housing 31, and the other end contacts the discharge body 34. The elastic force of the return spring 33 causes the bottom of the pressure relief body 35 to contact the stepped pipe 312.

[0029] In order to control the pressure in the pot body 1 during cooking and avoid danger caused by excessive pressure, automatic pressure relief can be achieved through the pressure relief body 35. That is, when the pressure in the pot body 1 does not exceed the designed maximum pressure value, the bottom of the pressure relief body 35 contacts the valve body shell 31. Figure 4 When the gas pressure inside the pot body 1 exceeds the designed maximum pressure value, that is, in the pressure relief state, the gas inside the pot body 1 will push up the pressure relief body 35 to form a gap, as shown in FIG. Figure 5 As shown, excess gas is discharged through the exhaust hole 311 .

[0030] In actual use, due to the continuous heating of food, the air pressure in the pot is getting higher and higher. When the pressure in the pot is too high, the sealing performance of the pot will be seriously damaged, and even dangerous. Therefore, when the pressure in the pot body 1 exceeds the designed maximum pressure value, the pressure relief body 35 is lifted up by the pressure in the pot body 1, so that a gap is generated between the pressure relief body 35 and the bottom of the valve body shell 31, and part of the gas is released to reduce the air pressure in the pot body 1. Obviously, the size of the designed maximum pressure value depends on the sum of the elastic force of the reset spring 33 and the gravity of the pressure relief body 35. When the preset pressure value is high, a reset spring 33 with a larger elastic force can be used or the weight of the pressure relief body 35 can be increased, so that the pressure relief body 35 will not be easily lifted up; when the designed maximum pressure value is low, a reset spring 33 with a smaller elastic force can be used, or the weight of the pressure relief body 35 can be reduced, or the reset spring 33 is not used, so that the pressure relief body 35 can be lifted up by a smaller pressure.

[0031] like Figure 6 , Figure 3 As shown, the linkage mechanism 4 includes a transmission rod group 41 and a magnetic float 42. The transmission rod group 41 is used to transmit the action of the magnetic float 42 to the safety valve 3. The magnetic float 42 is made of magnetic material, such as an alloy material of iron, cobalt, and nickel, and is used to generate movement under the magnetic force of the electromagnetic attraction mechanism 5. In order to realize the action control of the gas release 34, one end of the transmission rod group 41 is hinged to the rotating part 37, and the other end is connected to the magnetic float 42. The magnetic float 42 is arranged on the edge of the pot cover 2. After the pot cover 2 is installed on the pot body 1, the magnetic float 42 is located directly above the electromagnetic attraction mechanism 5, so that the electromagnetic attraction mechanism 5 drives the magnetic float 42 to move through the magnetic attraction, and then transmits the movement of the magnetic float 42 through the transmission rod group 41 to drive the gas release 34 to rotate.

[0032] In some embodiments of the present application, Figure 3 , Figure 6 As shown, the transmission rod group 41 includes a first connecting rod 411, a transmission rod 412 and a second connecting rod 413. One end of the first connecting rod 411 is hinged to the rotating part 37, and the other end is connected to the transmission rod 412, so as to convert the movement of the transmission rod 412 into the rotation of the discharge body 34; one end of the second connecting rod 413 is connected to the magnetic float 42, and the other end is connected to the transmission rod 412, so as to transmit the movement of the magnetic float 42 to the transmission rod 412.

[0033] In this embodiment, the movement of the magnetic float 42 can be transmitted through the interaction between the first connecting rod 411, the transmission rod 412 and the second connecting rod 413. That is, the movement of the magnetic float 42 in the vertical direction is first transmitted to the transmission rod 412 through the second connecting rod 413, so that when the magnetic float 42 moves in the vertical direction, the transmission rod 412 also moves. Then, through the first connecting rod 411, the movement of the transmission rod 412 is transmitted to the rotating part 37, so that the movement of the transmission rod 412 is converted into the rotation of the discharge gas 34.

[0034] In some embodiments of the present application, Figure 6 As shown, the magnetic float 42 further includes a floating shaft 421, a floating block 422 and a floating spring 423; the floating block 422 has a block structure made of magnetic material; the floating shaft 421 penetrates the floating block 422 and the floating spring 423. In this embodiment, the floating shaft 421 can make the floating block 422 move along the floating shaft 421, so the floating shaft 421 can be set to a vertically placed state, thereby making the floating block 422 move in the vertical direction. In addition, the floating shaft 421 can also facilitate the realization that after the pot cover 2 is installed on the pot body 1, the position of the floating block 422 corresponds to the position of the electromagnetic attraction mechanism 5, so that the floating block 422 is easily attracted by the magnetic force generated by the electromagnetic attraction mechanism 5.

[0035] The lower end of the floating spring 423 is connected to the floating block 422, and the upper end is fixed to the outer shell of the pot body 1, so that the floating block 422 is reset by the elastic force of the floating spring 423. When the electromagnetic attraction mechanism 5 does not attract the floating block 422, the floating spring 423 can restore the position of the floating block 422 to the initial position through its elastic force, so that the pot cover 2 can be opened.

[0036] Furthermore, if Figure 6 As shown, the electromagnetic attraction mechanism 5 includes an electromagnetic coil 51 and an adsorbent 52; the adsorbent 52 is arranged on the top of the electromagnetic coil 51, so that after the electromagnetic coil 51 is energized, the adsorbent 52 produces an adsorption effect on the magnetic float 42. In this embodiment, the adsorbent 52 can be a cylindrical structure made of soft magnetic material. The electromagnetic coil 51 is wound around the adsorbent 52. Through the magnetic effect of the current, the electromagnetic coil 51 generates magnetism after being energized, and adsorbs the floating block 422. Due to the use of soft magnetic materials, after the electromagnetic coil 51 is powered off, the magnetism on the adsorbent 52 will quickly disappear, so that the floating block 422 returns to its initial position.

[0037] In some embodiments of the present application, the pressure cooker further includes a controller 6 and a pressure sensor 7; the pressure sensor 7 is disposed on the inner side wall of the pot body 1, and the controller 6 is respectively connected to the electromagnetic attraction mechanism 5 and the pressure sensor 7, so as to detect the air pressure inside the pot body 1 through the pressure sensor 7, and control the electromagnetic attraction mechanism 5 to stop attracting the magnetic float 42 when the air pressure is balanced with the outside. By providing the controller 6 and the pressure sensor 7, when the pressure cooker is deflated, it can be automatically determined whether the pressure inside the pot body 1 is balanced with the outside, so as to automatically control the magnetic force of the electromagnetic attraction mechanism 5 on the magnetic float 42, so that the pot cover 2 can be opened manually.

[0038] Furthermore, the pressure cooker provided in the present application may also include a communication module, which can establish a communication connection between the user's smart terminal device, such as a mobile phone, a tablet computer, etc., and the electromagnetic attraction mechanism 5 or the controller 6, so as to control the electromagnetic attraction mechanism 5 using the smart terminal device, that is, the communication module can send the operation instruction on the user terminal to the controller 6 or the electromagnetic attraction mechanism 5, so that it produces a corresponding action. For example, when the user is about to perform a deflation operation, a control instruction can be issued through the smart terminal device, and after receiving the control instruction, the controller 6 or the electromagnetic attraction mechanism 5 controls the electromagnetic coil 51 to be energized to form a magnetic attraction effect.

[0039] It can be seen from the above technical solutions that when the intelligent pressure-controlled pressure cooker provided by the present application is actually used, if the air pressure generated in the pot body 1 during cooking is higher than the preset value, the pressure relief body 35 in the safety valve 3 is lifted up, and a gap is formed between the pressure relief body 35 and the valve body shell 31, so that the gas in the pot body 1 is discharged from the pot body 1 through the formed gap and the exhaust hole 311. When the air pressure in the pot body 1 is lower than the preset value, the return spring 33 returns the pressure relief body to its original position to maintain the high pressure in the pot body 1.

[0040] When the cooking is finished and the gas needs to be released, the electromagnetic attraction mechanism 5 is started to generate magnetism, and the magnetic float 42 is attracted to form a motion, and the motion formed is transmitted to the gas release body 34 through the linkage mechanism 4, so that the gas release body 34 rotates, so that the first gas release hole 361 in the gas release body 34 and the second gas release hole 362 in the pressure relief body 35 are connected to form a gas release channel, and the gas in the pot body 1 is released to reduce the air pressure in the pot body 1. The present application can complete the pressure control and gas release control through a safety valve 3, avoid setting multiple valve bodies on the pot cover 2, improve the reliability of the pressure cooker, and realize the release of gas in the pot body 1 through electromagnetic adsorption, avoid manually opening the gas release valve, and reduce the chance of scalding.
