Description

Technical Field

[0001] The present invention relates to the technical field of electric pressure cooker performance detection, and in particular to an electric pressure cooker component performance detection device and method. Background Art

[0002] An electric pressure cooker is a kitchen appliance that combines traditional pressure cookers with modern electronic technology. It can cook food quickly by precisely controlling internal pressure. Common electric pressure cookers are mainly composed of key components such as an inner pot, a heating base, a lid and an air pressure valve.

[0003] Among these components, the air pressure valve is the core component to ensure the safe operation of the electric pressure cooker. It has the important responsibility of releasing the internal pressure in a timely manner during operation. To ensure that the newly manufactured air pressure valve can reliably perform this task, it is usually subject to a series of rigorous tests before being put into use to verify that its performance meets the usage standards.

[0004] The air pressure valve generally consists of an air outlet pipe with a threaded groove on the outer wall (not shown in the figure), a cylindrical shell with a plurality of strip-shaped through grooves on the end face, and a conical shell with a plurality of exhaust grooves on the outer wall. The cylindrical shell is fixedly connected to the exhaust pipe (such as Fig.14 shown).

[0005] The performance test of the air pressure valve is mainly to test its functionality. Specifically, by adding liquid to the inner pot and heating it, it is observed whether the conical shell of the exhaust valve can automatically rise and lock as the temperature and pressure rise, so as to judge whether the air pressure valve meets the use requirements. However, in actual applications, since the inner pot may contain food with different viscosities or shapes, the existing testing methods are difficult to fully cover all usage scenarios, which affects the accuracy and completeness of the test results. When faced with liquid levels at different heights, it is difficult to ensure that the air pressure valve can operate normally under various conditions by relying solely on heated liquid testing.

[0020] S1: Pour different detection liquids into different detection areas, seal the storage shell into a whole through the rotation of the annular support sleeve and the fan-shaped block, and heat the detection liquid inside the storage shell through the heating belt.

[0021] S2: While the heating work is in progress, the stirring part 1 and the stirring part 2 inside the storage shell are driven by the external drive motor to work, so as to achieve the stirring work of the detection liquid, and ensure that the detection liquid is intermittently in contact with the air pressure valve.

[0025] 1. The present invention divides the storage housing into several detection areas by a partition plate, and injects liquids of different forms or heights into the several detection areas, so as to meet the diversity of the air pressure valve detection work and improve the efficiency of the air pressure valve detection work.

[0026] 2. In the present invention, the heating belt that moves back and forth up and down is used to heat the detection liquid inside the storage shell, thereby ensuring the uniformity of the heating effect. At the same time, during the heating process, different stirring devices inside each detection area are used to stir the detection liquid. By simulating the different cooking states of different liquids in the electric pressure cooker, the diversity of the air pressure valve detection work and the accuracy of the detection results are further improved.

[0027] 3.

[0046] Please refer to Figure 3 and Figure 6 The storage mechanism 2 includes a storage shell 21, a circular column 22 is fixedly arranged in the vertical direction at the center position inside the storage shell 21, and a plurality of partition plates 221 are fixedly arranged in the circumferential direction on the outer wall of the circular column 22. The partition plates 221 divide the storage shell 21 into a plurality of detection areas. The inner wall of the storage shell 21 is also provided with a matching groove group 24 corresponding to the plurality of detection areas. The lower end surface of the storage shell 21 is also provided with a discharge groove 211 corresponding to the plurality of detection areas. The storage mechanism 2 also includes a heating portion 23 which is matched with the outer wall of the storage shell 21.

[0047] Please refer to Figure 7 and Figure 8 The stirring mechanism 3 includes a stirring part 1 31 and a stirring part 2 32 , and the stirring part 1 31 and the stirring part 2 32 are alternately arranged in different detection areas in sequence, and the stirring part 1 31 and the stirring part 2 32 are both arranged on the driven gear 133 .

[0048] Please refer to Figure 1 , Fig.13 and Fig.14 The protection mechanism 4 includes an annular supporting sleeve 41 rotatably arranged on the upper end surface of the storage shell 21, and a sector block 42 with an internal cavity and a threaded groove in the center is fixedly arranged on the inner wall of the annular supporting sleeve 41 corresponding to a plurality of detection areas, and a mounting through groove is opened on the sector block 42, and a side of the lower end surface of the sector block 42 away from the circular column is also provided with a yield groove 421 upwardly, and a protection part 43 matching with the matching groove group 24 is installed inside the sector block 42.

[0049] Please refer to Fig.14The air pressure valve 5 is composed of an air outlet pipe (not shown in the drawings) with a threaded groove on the outer wall, a cylindrical shell 51 with a plurality of strip-shaped through grooves 511 on the end face, and a conical shell 52 with a plurality of exhaust grooves 521 on the outer wall. The cylindrical shell 51 is fixedly connected to the exhaust pipe.

[0050] During the specific operation, different types of detection liquids are first manually introduced into the detection area in the storage shell 21. At the same time, the air pressure valve 5 is screwed and fixed through the cooperation of the threaded groove on the exhaust pipe and the threaded groove on the fan block 42. Then, the conical shell 52 to be detected is pressed on the top of the exhaust pipe, and then the protection mechanism 4 is placed on the top of the storage shell 21 and the storage shell 21 is sealed into a whole through the annular supporting sleeve 41 and the fan block 42. Then, the external drive motor is controlled to drive the active gear 132 and the driven gear 133 to engage and rotate. At this time, the stirring part 1 31 and the stirring part 2 32 are driven by the corresponding driven gears 133 to rotate and stir the liquids inside their respective detection areas. At the same time, the heating belt 231 is started and the heating belt 231 heats different liquids in the detection area to simulate the normal heating environment of the pressure cooker.

[0051] When the external driving motor drives the driving gear 132 to rotate, the annular shell 11 also rotates under the meshing of the ring gear 12 and a plurality of driven gears 133, and the heating part 23 is driven to move back and forth up and down through the rotation of the annular shell 11, and the heating part 23 is driven to move back and forth up and down through the spiral groove 111 of the annular shell 11 to ensure the uniformity of the heating effect and avoid the problem that the pressure cooker cannot simulate the real usage environment due to local overheating.

[0052] As the heating part 23 continues to work, the air pressure inside different detection areas gradually increases. At this time, the stirring part 1 31 and the stirring part 2 32 continue to work to stir the liquid inside each of them upward and make it contact with the corresponding air pressure valve 5. Through the continuous heating of the heating part 23 and the continuous contact between the detection liquid and the air pressure valve 5, the influence of different liquids in contact with the air pressure valve 5 on the air pressure valve 5 during the use of the pressure cooker is simulated, and the exhaust of the air pressure valve 5 is used to judge how long the heating will take before the air pressure valve 5 will be blocked.

[0053] When the air pressure valve 5 is blocked and the air pressure inside the detection area is too high, the air pressure will push up the protection part 43 and release the air pressure inside the detection area, thereby preventing the detection equipment from exploding due to excessive air pressure.

[0054] It should be noted that, when the air pressure valve 5 is in the initial state and the air pressure inside the detection area is low, the lower end surface of the conical shell 52 of the air pressure valve 5 fits with the upper end surface of the sector block 42 .

[0055] Please refer to Figure 1 , Figure 3 and Figure 4 The teeth of the gear ring 12 are arranged on the inner wall and four connecting plates 121 are fixedly arranged on the outer wall of the gear ring 12 in a circular array. The upper end surfaces of the four connecting plates 121 are fixedly connected to the annular shell 11, and the lower end surfaces of the four connecting plates 121 are rotatably mounted with an annular connecting platform 122, and four supporting seats 14 are fixedly arranged on the lower end surface of the annular connecting platform 122 in a circumferential direction.

[0056] Please refer to Figure 6 and Figure 7 The mating groove group 24 includes a vertical avoidance groove 241 and an arc-shaped sliding groove 242 connected to the avoidance groove 241. A strip sliding groove 243 is also provided on the inner wall of the storage shell 21 and located above the arc-shaped sliding groove 242. The strip sliding groove 243 is connected to the arc-shaped sliding groove 242. The inner wall of the storage shell 21 is connected to the strip sliding groove 243, and the end face of the strip sliding groove 243 is provided with three locking grooves 244 in the vertical direction. The upper and lower corners of the locking groove 244 are both set as inclined surfaces. Rubber expansion blocks (not shown in the drawings) are slidably provided inside the avoidance groove 241, the arc-shaped sliding groove 242 and the locking groove 244.

[0057] Please refer to Fig. 9 , Fig.13 and Fig.14 The protection portion 43 includes two circular plates 431 fixedly arranged inside the mounting groove in the up and down directions, and the end surface of the circular plate 431 is provided with a plurality of tapered grooves 432 with diameters gradually decreasing downward in the circumferential direction, and a tapered plug 433 is arranged inside the tapered groove 432, and the upper and lower tapered plugs 433 are fixedly connected by a circular rod 434, and a plurality of circular rods 434 are fixedly connected with a linkage plate 435, and the linkage plate 435 is located between the two circular plates 431, and an inverted Z-shaped rod 436 is fixedly connected to the linkage plate 435, and the side of the inverted Z-shaped rod 436 away from the linkage plate 435 is set as a spring expansion section, and the upper and lower corners of the spring expansion section away from the linkage plate 435 are set in an inclined shape and located inside the locking groove 244.

[0058] After the detection liquid is poured into the corresponding detection area, the annular supporting sleeve 41 and the fan-shaped block 42 are manually placed on the storage shell 21, so that the inverted Z-shaped rod 436 pushes the rubber expansion block inside the avoidance groove 241 and slides downward along the avoidance groove 241. Then, the annular supporting sleeve 41 and the fan-shaped block 42 are rotated to make the spring expansion section of the inverted Z-shaped rod 436 rotate and slide along the arc-shaped sliding groove 242, and finally get stuck in the corresponding locking groove 244, thereby completing the sealing work of the storage shell 21.

[0059] Please refer to Fig. 9 , Fig.10 and Fig.11 The stirring part 31 includes a support column 311 which is fixedly connected to the corresponding driven gear 133 and has a plurality of teeth 3111 on the outer wall. The outer wall of the support column 311 is fixedly sleeved with two annular rings 312 in the up and down directions. The outer wall of the annular ring 312 is fixedly provided with three stirring blades 313 in the circumferential direction. The stirring part 31 also includes a stirring group 314 matched with the stirring blades 313.

[0060] Please refer to Fig.10 and Fig.11 The stirring group 314 includes an annular mounting platform 3141 which is rotatably arranged inside the detection area and has a cavity at the bottom. The inner side wall of the cavity of the annular mounting platform 3141 is fixedly provided with a plurality of teeth 2 along the circumferential direction. The support column 1 311 passes through the annular mounting platform 3141, and is located in the cavity part of the annular mounting platform 3141 and is rotatably provided with three matching gears 3142 which are always meshed with the teeth 1 3111 and the teeth 2. The upper end surface of the annular mounting platform 3141 is also provided with three slide grooves in the circumferential direction. The interior of each of the slide grooves is provided with a telescopic support block 3143 through spring sliding. The stirring group 314 also includes an arc-shaped mounting plate 3144 whose side wall is set as an inclined surface. Three arc-shaped mounting plates 3144 are provided corresponding to the telescopic support blocks 3143 and are respectively fixedly connected to the corresponding telescopic support blocks 3143. A side wall of the arc-shaped mounting plate 3144 close to the telescopic support block 3143 is fixedly provided with multiple stirring blades 3145 in the up and down directions. The multiple stirring blades 3145 are staggered with the stirring blade 1 313.

[0061] Please refer to Fig.12 The second stirring part 32 includes a second support column 321 fixedly connected to the corresponding driven gear 133, and the outer wall of the second support column 321 is fixedly provided with a spiral blade 322 spirally upward.

[0062] Please refer to Figure 6 The heating part 23 includes a heating belt 231 sleeved on the outer wall of the storage shell 21, and the outer wall of the heating belt 231 is fixedly provided with two annular supporting strips 232 in the up and down directions. The outer wall of the annular supporting strip 232 is fixedly provided with a spherical block 233 corresponding to the intersection of the two spiral grooves 111. The spherical part of the spherical block 233 is always located inside the spiral groove 111. The heating part 23 also includes a limiting rod 234 that movably passes through the two spherical blocks 233, and the limiting rod 234 is fixedly connected to the storage shell 21 upward.

[0063] When the storage shell 21 is sealed into a whole, the external drive motor is started to drive the active gear 132 and the driven gear 133 to rotate. At this time, the support column 1 311 and the support column 2 321 corresponding to the driven gear 133 rotate synchronously, and then the stirring blade 1 313 arranged on the support column 1 311 is used to stir the liquid in the corresponding detection area, and the spiral blade 322 arranged on the support column 2 321 is used to stir the liquid inside the corresponding detection area upward. When the support column 1 311 rotates, a plurality of teeth 1 3111 arranged on its outer wall engage with three matching gears 3142. The three matching gears 3142 drive the annular mounting platform 3141 to realize the mutual reversal with the stirring blade 3145 through the principle of planetary gears. The detection liquid inside the corresponding detection area is driven to continuously surge upward and contact the corresponding air pressure valve 5 through the rotation of the stirring blade 1 313 and the stirring blade 2 3145 in opposite directions.

[0064] While stirring the detection liquid inside several detection areas, the heating belt 231 is controlled to heat up and heat the detection liquid inside the storage shell 21. When the annular shell 11 rotates under the meshing of the driving gear 132, the driven gear 133 and the ring gear 12, the annular shell 11 drives the spherical block 233 and the heating belt 231 to slide back and forth up and down along the spiral groove 111 and the limit rod 234.

[0065] It should be noted that the detection liquid introduced into the detection area of ​​the stirring part 31 is more viscous. When the stirring blade 313 and the stirring blade 3145 are rotating in opposite directions for stirring, the telescopic support block 3143 and the arc-shaped mounting plate 3144 arranged inside the slide groove intermittently contact and cooperate with the partition plate 221. The scraping work of the detection liquid on the side wall of the partition plate 221 is realized by the inclined surface arranged on the side wall of the arc-shaped mounting plate 3144, so as to prevent the detection liquid hanging on the wall from adhering to the partition plate 221 after being heated. The purpose of setting the limit rod 234 on the two spherical blocks 233 is to ensure the direction in which the heating belt 231 slides up and down.

[0066] As the heating belt 231 heats the detection liquid inside the storage shell 21, the detection liquid inside each detection area gradually boils. At this time, the water vapor inside the detection area will pass through the strip groove 511 and the exhaust pipe. At this time, the water vapor will push up the conical shell 52 when passing through the exhaust pipe, and exhaust work will be performed through the exhaust groove 521 opened on the conical shell 52.

[0067] As the stirring work inside each detection area continues, the detection liquid will intermittently contact the cylindrical shell 51 of the air pressure valve 5. By simulating the extreme usage scenarios of the air pressure valve 5, that is, the contact between liquids of different viscosities and the cylindrical shell 51, it is possible to determine whether the air pressure valve 5 will be blocked during actual use.

[0068] When the heating time and stirring time are too long, resulting in blockage of the cylindrical shell 51 of the air pressure valve 5, the water vapor cannot be quickly discharged from the exhaust pipe and the exhaust groove 521, and the pressure of the water vapor pushes the spring expansion section of the inverted Z-shaped rod 436 to move upward to the locking groove 244 in the middle. When the inverted Z-shaped rod 436 moves upward, the linkage plate 435 and the circular rod 434 also move upward under the drive of the inverted Z-shaped rod 436. At this time, the conical plug 433 is separated from the conical groove 432 and a certain gap is generated between the conical plug 433 and the conical groove 432, and the excess water vapor inside the detection area will be discharged along the gap.

[0069] As the heating and stirring work continues, when the cylindrical shell 51 is completely blocked and the gap on the circular plate 431 can no longer meet the discharge of water vapor, the spring expansion section on the inverted Z-shaped rod 436 is continued to be pushed upward, and then the spring expansion section moves to the top locking groove 244. At this time, a larger gap is generated between the conical plug 433 and the conical groove 432 to meet the normal discharge of water vapor, ensure the safety of the detection work of the air pressure valve 5, and avoid explosions due to excessive water vapor inside the detection area.

[0070] Finally, after the detection of the air pressure valve 5 is completed, an external cleaning device is used to connect to the plurality of discharge slots 211 , and the residual detection liquid inside the detection area is cleaned by the cleaning device and finally discharged through the discharge slots 211 .

[0071] In addition, the present invention also provides a method for detecting the performance of an electric pressure cooker assembly, comprising the following steps:

[0072] S1: Pour different detection liquids into different detection areas, seal the storage shell 21 into a whole through the rotation of the annular support sleeve 41 and the sector block 42, and heat the detection liquid inside the storage shell 21 through the heating belt 231.

[0073] S2: While the heating work is in progress, the stirring part 1 31 and the stirring part 2 32 inside the storage shell 21 are driven by the external drive motor to work, so as to achieve the stirring work of the detection liquid, and ensure that the detection liquid is intermittently in contact with the air pressure valve 5. While the external drive motor is working, the driven gear 133 engages with the ring gear 12 to drive the annular shell 11 to rotate, so that the heating belt 231 reciprocates along the spiral groove 111 and the limit rod 234 to ensure the uniformity of heating.

[0074] S3: After heating and stirring for a period of time, observe whether the water vapor in each detection area is discharged smoothly from the air pressure valve 5. Through the continuous stirring of the stirring part 1 31 and the stirring part 2 32, simulate the contact between the liquids of different viscosities and the cylindrical shell 51 under extreme conditions. After a period of heating and stirring, the air pressure inside the detection area gradually increases, and the excess air pressure will be discharged from the exhaust pipe and push up the conical shell 52, and at the same time be discharged from several exhaust grooves 521. At this time, observe whether the exhaust of the exhaust groove 521 is smooth. If, with the increase of heating and stirring time, the exhaust grooves 521 on the conical shell 52 are still able to exhaust smoothly, and the conical plugs 433 in the two circular plates 431 are not lifted up by the air pressure, it means that the functionality of the air pressure valve 5 is normal. On the contrary, after a period of heating and stirring, it is obviously observed that the exhaust grooves 521 on the conical shell 52 are difficult to exhaust, a small number of exhaust grooves 521 are not ventilated, and the conical plugs 433 inside the two circular plates 431 are lifted up and participate in the exhaust work, which means that the functionality of the air pressure valve 5 is abnormal.

[0075] S4: Finally, after the detection is completed, the air pressure valve 5 is connected to a plurality of discharge slots 211 using an external cleaning device, and the residual detection liquid inside the detection area is cleaned by the cleaning device and finally discharged through the discharge slot 211.
