Description

Technical Field

[0001] This invention relates to the field of air fryer technology, specifically to an integrated suction and exhaust pump and an air fryer system thereof. Background Technology

[0002] Air fryers are common kitchen appliances used for baking food. During the baking process, air fryers typically use nozzles to spray water mist onto the food to prevent it from burning. The nozzles deliver water through a pump and a water outlet pipe. However, after the food is baked, the pump stops pumping water, leaving residual water in the water outlet pipe and nozzle. Currently, the pumps in air fryers only have a one-way pumping function, which prevents them from sucking out the residual water in the water outlet pipe and nozzle. As a result, the residual water inside the nozzle drips onto the food after baking, causing a decrease in food quality and affecting its taste. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated suction and exhaust pump and an air fryer system thereof. The integrated suction and exhaust pump has the dual functions of water suction and water pumping. When applied to an air fryer, it can pump the water remaining at the outlet pipe and nozzle back into the water tank after the food is baked, preventing residual water droplets from falling onto the baked food and effectively ensuring the taste of the food after baking.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A pump integrating suction and discharge includes an upper pump head body and a lower pump head body distributed vertically. The upper pump head body has a first water outlet chamber and a first water passage chamber, and the lower pump head body has a second water outlet chamber and a second water passage chamber. The first water passage chamber is connected to the water inlet, and the second water passage chamber is connected to the water outlet. A first water sealing ring and a second water sealing ring are respectively provided on the water passage connecting the first water outlet chamber and the second water passage chamber, and the second water outlet chamber and the first water passage chamber. A water control component is provided on the water passage connecting the first water sealing ring and the second water sealing ring to alternately seal or block the water passage. A first pumping component is provided on the water passage connecting the water inlet and the first water outlet chamber, and a second pumping component is provided on the water passage connecting the second water passage chamber and the second water outlet chamber. The pump also includes a power mechanism with two output ends. The two output ends are respectively connected to a first driving component and a second driving component to drive the first pumping component and the second pumping component to alternately operate.

[0006] Due to the adoption of the above technical solution, this integrated pump has two pumping parts: an upper pump head and a lower pump head. The upper pump head can pump water from the inlet to the outlet: the power mechanism drives the first drive assembly to operate, at which time the second drive assembly stops operating. The first drive assembly drives the first pumping assembly to draw in source water from the inlet, and then pumps it to the first outlet chamber. The water control assembly controls the water passage at the first sealing ring to be connected, and the water passage at the second sealing ring to be blocked. The water in the first outlet chamber enters the second water passage chamber and is finally discharged from the outlet. The lower pump head can pump water from the outlet to the inlet: when there is residual water at the rear end of the pump outlet, the power mechanism drives the second pump head... When the drive component is activated, the first drive component stops operating. The second drive component drives the second water pump component to draw in the residual water from the outlet and pump it to the second water outlet chamber. The water control component controls the water passage at the second sealing ring to be connected, while the water passage at the first sealing ring is blocked. The water in the second water outlet chamber enters the first water passage chamber and is finally discharged from the clean water outlet, achieving a bidirectional water pumping effect. The integrated suction and discharge pump has the dual functions of water suction and water pumping. When applied to an air fryer, it can pump the residual water at the outlet pipe and nozzle back into the water tank after the food is baked, preventing residual water droplets from falling onto the baked food and effectively ensuring the taste of the baked food.

[0026] Example 1

[0027] A pump integrating suction and discharge includes an upper pump head body 32 and a lower pump head body 57 distributed vertically. The upper pump head body 32 has a first water outlet chamber 35 and a first water passage chamber 34, and the lower pump head body 57 has a second water outlet chamber 55 and a second water passage chamber 49. The first water passage chamber 34 is connected to the water inlet 31, and the second water passage chamber 49 is connected to the water outlet 56. A first sealing ring 44 and a second sealing ring 45 are respectively provided on the water passage connecting the first water outlet chamber 35 and the second water passage chamber 49, and the second water outlet chamber 55 and the first water passage chamber 34. The water ring 41 and the water control component that controls the alternating sealing or blocking of the water passages at the first sealing ring 44 and the second sealing ring 41 are provided with a first water pump component on the water passage connecting the inlet 31 and the first outlet chamber 35, and a second water pump component on the water passage connecting the second water passage 49 and the second outlet chamber 55. The system also includes a power mechanism with two output ends, which are respectively connected to a first drive component and a second drive component that drive the first water pump component and the second water pump component to operate alternately.

[0028] In this embodiment, existing pumps all have a pump head body and can only pump water in one direction, such as... Figure 1 , Figure 2 , Figure 3As shown, the integrated pump 83 has two pumping components: an upper pump head body 32 and a lower pump head body 57. The two pump head bodies are sealed together by a first sealing ring 46. The power mechanism has two output ends, which are used to alternately drive the first drive assembly and the second drive assembly. The two drive assemblies are symmetrically distributed at the upper and lower ends of the power mechanism. The first drive assembly and the second drive assembly drive the first pumping assembly and the second pumping assembly to pump water alternately. The two pumping assemblies are symmetrically distributed vertically. Specifically, the upper pump head 32 can pump water from the inlet 31 out of the outlet 56: the power mechanism drives the first drive assembly to operate, at which time the second drive assembly stops operating. The first drive assembly drives the first pump water assembly to draw in source water from the inlet 31 and then pump it to the first outlet chamber 35. The water control assembly controls the water passage at the first sealing ring 44 to be connected and the water passage at the second sealing ring 41 to be blocked. The water in the first outlet chamber 35 enters the second water passage chamber 49 and is finally discharged from the outlet 56. The lower pump head 57 can pump water from the outlet 56 out of the inlet 31: when there is residual water at the rear end of the pump outlet 56, the power mechanism drives the second drive assembly to operate, at which time the first drive assembly... When the component stops operating, the second drive component drives the second water pump component to draw in the residual water from the outlet 56 and then pump it to the second water outlet chamber 55. The water control component controls the water passage at the second sealing ring 41 to be connected and the water passage at the first sealing ring 44 to be blocked. The water in the second water outlet chamber 55 enters the first water passage chamber 34 and is finally discharged from the clean water outlet, achieving the effect of bidirectional water pumping. The integrated suction and discharge pump 83 has the dual functions of water suction and water pumping. When applied to the air fryer system, it can pump the residual water at the outlet pipe 84 and nozzle 85 back into the water tank 81 after the food is baked, preventing residual water droplets from falling on the baked food and effectively ensuring the taste of the baked food.

[0029] Example 2

[0030] Preferably, the water control assembly includes an integrally formed left end cap 42, a right end cap 40, a pressure-sensitive diaphragm 48, and a return spring 43. The pressure-sensitive diaphragm 48 is disposed circumferentially at the connection between the left end cap 42 and the right end cap 40. The pressure-sensitive diaphragm 48 is circumferentially pressed between the pressure plate 54 and the upper pump head body 32 and the lower pump head body 57. The right side of the pressure plate 54 is clamped with a sealing plate 47. One end of the return spring 43 acts on the pressure-sensitive diaphragm 48, and the other end acts on the pressure plate 54. The left end cap 42 seals the first water sealing ring 44, and the right end cap 40 seals the second water sealing ring 41. The left end cap 42 and the right end cap 40 move laterally under the combined action of the water pressure in the first water outlet chamber 35, the water pressure in the second water outlet chamber 55, and the return spring 43 to form a water control assembly that controls the alternating sealing or blocking of the water passages at the first water sealing ring 44 and the second water sealing ring 41.

[0031] Preferably, the upper pump head body 32 is provided with a first water passage 45 that communicates with the second water outlet chamber 55. The left end cap 42 is located on the water path that connects the first water passage 45 and the first water outlet chamber 35. A second water passage 50 is formed between the sealing plate 47 and the pressure plate 54. The inner side of the pressure plate 54 has a third water outlet chamber 53 that communicates with the second water outlet chamber 55. The lower side of the pressure plate 54 is provided with a second water passage hole 51 that communicates with the third water outlet chamber 53 and the second water outlet passage. The first water passage chamber 34 and the inlet 31 are located between... The water passage is provided with a first water passage hole 33 located on the pressure plate 54, and a third water passage hole 39 connected to the second water passage channel 50 is provided in the middle of the second water sealing ring 41. The pressure plate 54 and the pressure-sensing diaphragm 48 form a third water passage cavity 37. The inner side of the pressure plate 54 is provided with a sleeve that is slidably connected to the right end cap 40. The side wall of the ring sleeve is provided with a fourth water passage hole 38 that connects the third water passage cavity 37 and the third water passage hole 39. The upper side of the pressure plate 54 is provided with a water passage groove 36 that connects the third water passage cavity 37 and the first water passage cavity 34.

[0032] The specific working principle of the water control component is as follows: When the power mechanism drives the first drive component to operate, the second drive component stops operating. When the first drive component drives the first water pump component to operate, the first water pump component draws in source water from the inlet 31. Some water also enters the first water passage chamber 34 and enters the third water passage chamber 37 from the water passage trough 36. After passing through the first water pump component, the source water is pumped to the first water outlet chamber 35. The water pressure in the first water outlet chamber 35 overcomes the elastic force of the return spring 43 and squeezes the pressure-sensitive diaphragm 48 to the right. The return spring 43 is compressed to the right. The pressure-sensitive diaphragm 48 is integrally formed with the two end caps. The left end cap 42 is smaller on the left end than on the right end. When the cone-shaped column is reached, the pressure-sensitive diaphragm 48 drives the two end caps to move to the right. After the left end cap 42 moves to the right, a gap is created between it and the inner wall of the upper pump head body 32, so that the left end cap 42 releases the seal on the water passage at the first water sealing ring 44. The water passage between the first water outlet chamber 35 and the first water passage 45 is connected. The source water enters the first water passage 45 from the first water outlet chamber 35 through the first water sealing ring 44, then enters the second water passage chamber 49, and finally exits from the water outlet 56, realizing positive pumping of water and delivering it to the nozzle 85 of the air fryer. The nozzle 85 sprays the source water in the form of water mist onto the food being baked in the pot body 86. After the left end cap 42 moves to the right, the side wall of the right end cap 40 seals the fourth water passage, and the end of the right end cap 40 presses and seals the second water sealing ring 41, sealing the third water passage hole 39 in the middle of the second water sealing ring 41, so that the source water in the third water passage cavity 37 will not flow into the flow channel.When residual water at the front end of outlet 56 needs to be treated, the power mechanism drives the second drive assembly to operate. At this time, the first drive assembly does not operate, and the first pump assembly also stops operating. At this time, there is no water pressure in the first outlet chamber 35, which cannot overcome the elastic force of the return spring 43. The return spring 43 resets and drives the pressure-sensing diaphragm 48 to move to the left, causing the left end cap 42 to move to the left to reseal the water passage at the first water sealing ring 44. The right end cap 40 moves to the left to release the seal on the water passage at the second water sealing ring 41. The water passage between the third water passage 39 and the fourth water passage 38 is connected. The second pump assembly operates to draw residual water from outlet 56 and then pumps it to the second outlet chamber 55 and the third outlet chamber 53. The third outlet chamber 53 is formed by the inner recess of the pressure plate 54. The third outlet chamber 53 and the second outlet chamber 55 are connected. The residual water then enters the second water passage 50 through the second water passage hole 51. The second water passage 50 is formed by the gap between the sealing plate 47 and the pressure plate 54. The pressure plate 54 has a second sealing ring 52 embedded on its outer side to prevent water from leaking to the outside. Then, the residual water in the second water passage 50 enters the third water passage cavity 37 through the third water passage hole 39 and the fourth water passage hole 38. The fourth water passage hole 38 is opened on the sleeve side wall formed by the pressure plate 54 protruding to the left. The inner cavity of the sleeve is adapted to the size of the right end cap 40 and plays a guiding role in the lateral movement of the right end cap 40. The residual water then enters the first water passage cavity 34 through the water tank 36 and is finally pumped out through the water inlet 31 to achieve reverse pumping. This pumps the residual water in the water outlet pipe 84 and nozzle 85 of the air fryer system back into the water tank 81 to prevent dripping water from affecting the taste of the baked food.

[0033] Example 3

[0034] Preferably, the first water pumping assembly includes a first water pumping section and a first transmission section, and the second water pumping assembly includes a second water pumping section and a second transmission section. The first water pumping section and the second water pumping section are symmetrically arranged, and the first transmission section and the second transmission section are symmetrically arranged. The power mechanism is located between the first transmission section and the second transmission section. The two output ends of the power mechanism drive the first transmission section and the second transmission section to rotate eccentrically through the first drive assembly and the second drive assembly, respectively, and control the first water pumping section and the second water pumping section to pump water alternately. Specifically, depending on the actual needs, whether to pump water in the forward or reverse direction, in the forward pumping direction, the power mechanism only drives the first drive component to operate. The first drive component drives the first transmission part to rotate eccentrically, and the eccentric rotation of the second transmission part drives the first pumping part to draw in the source water from the inlet 31 and pump it out from the outlet 56. In the reverse pumping direction (water suction), the power mechanism only drives the second drive component to operate. The second drive component drives the second transmission part to rotate eccentrically, and the eccentric rotation of the second transmission part drives the second pumping part to draw in the residual water at the front end of the outlet 56 (inlet pipe 82, nozzle 85) and pump it out from the inlet 31, thus achieving the bidirectional pumping function.

[0035] Preferably, the first pumping part and the second pumping part are respectively embedded in the side of the upper pump head body 32 and the lower pump head body 57. The upper housing 30 and the lower housing 09 are snapped onto the left side of the upper pump head body 32 and the lower pump head body 57. The top of the upper housing 30 and the bottom of the lower housing 09 are respectively provided with mounting cavities for installing the first transmission part and the second transmission part. The top of the upper housing 30 is snapped onto the matching upper cover plate 29, and the bottom of the lower housing 09 is snapped onto the matching lower cover plate 02. A cavity for installing the power mechanism is formed between the upper housing 30 and the lower housing 09.

[0036] Preferably, the power mechanism is a dual-head motor 16. A first drive assembly is connected to the upper end of the output shaft 15 of the dual-head motor 16. The first drive assembly includes a first nut 19, a first screw 18, a first active magnet ring 21, a first driven magnet ring 24, and a first rotating shaft 22. The middle part of the first screw 18 is fixedly connected to the upper end of the output shaft 15. A first limiting pin 20 and a second limiting pin 17 are distributed on the side wall of the first screw 18. The first nut 19 is threadedly connected to the first screw 18 and located at the first limiting pin 20. 0. Between the second limiting pins 17, the first active magnet ring 21 is fixed in the groove at the top of the first nut 19 and located in the cavity.

A second outlet check valve 60 is provided on the water path connecting the second pressurizing chamber 62 and the second outlet hole 61.

[0040] The specific working principle of the bidirectional water pump in this embodiment is as follows: Figure 1-3As shown, when forward pumping is required (from inlet 31 to outlet 56), the output shaft 15 of the dual-head motor 16 rotates forward. The two ends of the output shaft 15 drive the first screw 18 and the second screw 13 to rotate respectively. Both the first screw 18 and the second screw 13 are threaded rods. The T-shaped first nut 19 is threadedly connected to the first screw 18, and the inverted T-shaped second nut 11 is also threadedly connected to the second screw 13. A first active magnet ring 21 and a second active magnet ring 10 are fixed to the top of the first nut 19 and the bottom of the second nut 11 respectively. The first nut 19 and the second nut 11 are relatively heavy, and their gravity can act as a vertical limit. Therefore, when the output shaft 15 rotates forward, the first nut 19 will move along the output shaft... The first screw 15 moves upward along its length until the first nut 19 contacts the first limit pin 20. The first nut 19 then rotates synchronously with the first screw 18. Simultaneously, the second nut 11 also moves upward along the length of the output shaft 15. The second active magnet ring 10 moves away from the second driven magnet ring 08 until the second nut 11 contacts the third limit pin 14, causing the second nut 11 to rotate with the second screw 13. Because the distance between the second active magnet ring 10 and the second driven magnet ring 08 is greater after the second active magnet ring 10 moves upward, they are no longer within the range of mutual induction, causing the second driven magnet ring 08 to lose its power source. Consequently, the second transmission unit will not drive the second pumping unit. At this time, the first active magnet ring 21 approaches... The first driven magnet ring 24 is not in contact with the first driven magnet ring 24, reaching a distance range where they can sense each other. The first active magnet ring 21 and the first driven magnet ring 24 have opposite polarities. Rotation of the first active magnet ring 21 will drive the first driven magnet ring 24 to rotate accordingly. The first driven magnet ring 24 will then drive the first turntable 25 to rotate, and the first turntable 25 will also drive the first rotating shaft 22 to rotate. The upper end of the first rotating shaft 22 is eccentrically connected to the first fixed block 28 after passing through the first eccentric seat 23. The first fixed block 28 is fixed in the mounting groove on the bottom surface of the upper cover plate 29. The first fixed block 28 can ensure the stability of the first rotating shaft 22. The inner ring of the first bearing 26 is sleeved on the first eccentric seat 23, and the outer ring of the first bearing 26 is sleeved with the first fixed sleeve 2. 7. Thus, the eccentric rotation of the first eccentric seat 23 will drive the eccentric rotation of the first fixed sleeve 27. The first fixed sleeve 27 is fixedly connected to the left end of the first diaphragm 80 by the first screw 79, the first U-shaped sleeve 78, and the circumferential of the first diaphragm 80 is pressed between the first partition 77 and the upper housing 30. The first partition 77 and the upper pump head body 32 are pressed together by the fourth sealing ring 70, which can improve the sealing of the connection and prevent water leakage. The eccentric rotation of the first fixed sleeve 27 drives the volume change of the first pressurizing chamber 87. When the volume increases, the source water in the inlet 31 is sucked into the eighth water passage 76. The water pressure in the eighth water passage 76 pushes open the first inlet one-way valve 75, and the source water enters the first pressurizing chamber 87 through the first inlet 74.When the volume of the first pressurizing chamber 87 decreases, the water pressure inside the first pressurizing chamber 87 pushes open the first outlet one-way diaphragm. Source water enters the first outlet chamber 35 from the first pressurizing chamber 87 through the first outlet hole 73 and the seventh water passage hole 71. Then, controlled by the water control assembly, the water path at the first sealing ring 44 is connected and the water is pumped out through the outlet 56, completing the forward pumping process.

[0041] When reverse pumping is required (from outlet 56 to inlet 31): the output shaft 15 of the dual-head motor 16 rotates in reverse, driving the first screw 18 and the second screw 13 to rotate in reverse at both ends of the output shaft 15. The first nut 19 then moves downward along the length of the output shaft 15 until it contacts the second limit pin 17. The first nut 19 then rotates synchronously with the first screw 18. Because the distance between the first active magnet ring 21 and the first driven magnet ring 24 is greater after the first active magnet ring 21 moves downward, it is no longer within the range of mutual induction, causing the first driven magnet ring 24 to lose its power source. Consequently, the first transmission unit will not drive the first pumping unit. At the same time, the second nut 11 also rotates along the length of the output shaft 15. Moving downwards, the second active magnet ring 10 moves closer to the second driven magnet ring 08 until the second nut 11 contacts the fourth limiting pin 12, causing the second nut 11 to rotate with the second screw 13. At this point, the second active magnet ring 10 is close to the second driven magnet ring 08 but not in contact, reaching a distance range where they can sense each other. The polarities of the second active magnet ring 10 and the second driven magnet ring 08 are opposite. The rotation of the second active magnet ring 10 can drive the second driven magnet ring 08 to rotate as well. The second driven magnet ring 08 will then drive the second turntable 07 to rotate, and the second turntable 07 will also drive the second rotating shaft 05 to rotate. The upper end of the second rotating shaft 05 eccentrically passes through the second eccentric seat 03 and rotates with the second fixed block 01. The connection is as follows: the second fixing block 01 is fixed in the mounting groove on the top surface of the lower cover plate 02. The second fixing block 01 ensures the stability of the second rotating shaft 05. The inner ring of the second bearing 04 is sleeved on the second eccentric seat 03, and the outer ring of the second bearing 04 is sleeved with the second fixing sleeve 06. Thus, the eccentric rotation of the second eccentric seat 03 will drive the eccentric rotation of the second fixing sleeve 06. The second fixing sleeve 06 is fixedly connected to the left end of the second diaphragm 69 by the second screw 68, the second U-shaped sleeve 67, and the second diaphragm 69 is pressed circumferentially between the second partition plate 66 and the lower housing 09. A third sealing ring 58 is pressed between the second partition plate 66 and the lower pump head body 57 to improve the sealing of the connection and prevent water leakage. The second fixing sleeve 06... The eccentric rotation causes a change in the volume of the second pressurizing chamber 62. When the volume increases, water from the outlet 56 is drawn into the second water passage chamber 49 and then into the sixth water passage hole 65. The water pressure in the sixth water passage hole 65 opens the second inlet one-way valve 64, and the water enters the second pressurizing chamber 62 through the second inlet hole 63. When the volume of the second pressurizing chamber 62 decreases, the water pressure in the second pressurizing chamber 62 opens the second outlet one-way diaphragm, and the water enters the second outlet chamber 55 and the third outlet chamber 53 from the second pressurizing chamber 62 through the second outlet hole 61 and the fifth water passage hole 59. Then, the water is transported to the first water passage chamber 34 after the water passage is connected by the water control component at the second sealing ring 41, and then pumped out from the inlet 31, completing the reverse pumping.

[0042] Example 4

[0043] An air fryer system includes a water tank 81, a nozzle 85, and a pot body 86. A suction pump 83 is provided on the water line connecting the water tank 81 and the nozzle 85. An inlet pipe 82 is provided between the inlet 31 of the suction pump 83 and the outlet of the water tank 81. An outlet pipe 84 is provided between the outlet 56 of the suction pump 83 and the nozzle 85. The nozzle 85 is located inside the upper part of the pot body 86.

[0044] In this embodiment, as Figure 1 and Figure 4 In this system, the integrated suction and exhaust pump 83 is installed between the nozzle 85 and the water tank 81 of the air fryer system. During the air fryer system's baking process, the output shaft 15 of the dual-head motor 16 of the integrated suction and exhaust pump 83 rotates in the forward direction, starting to pump water in the forward direction. The second active magnet ring 10 then moves away from the second driven magnet ring 08, and the second transmission unit loses its power source. The first active magnet ring 21 moves closer to the first driven magnet ring 24. Once the distance between them reaches the sensing distance, the first active magnet ring 21 will drive the first driven magnet ring 24. When the moving magnet ring 24 rotates, the first driven magnet ring 24 drives the first transmission part to rotate eccentrically, thereby changing the volume of the first pressurizing chamber 87. When the volume increases, the source water in the water tank 81 is drawn into the first pressurizing chamber 87 through the water inlet pipe 82 and the water inlet 31, and then pumped to the first water outlet chamber 35. The water control component then controls the water circuit at the first water sealing ring 44 to be connected, and then pumped to the water outlet 56. The water outlet pipe 84 then delivers the water to the nozzle 85, and the nozzle 85 sprays water mist onto the food in the pot body 86. To prevent the food surface from burning; once the food inside the pot 86 is cooked, the suction and discharge pump will stop pumping water in the forward direction. Residual water will remain in the nozzle 85 and water outlet pipe 84. At this point, the suction and discharge pump will start pumping water in the reverse direction, the output shaft 15 of the dual-head motor 16 will reverse, and the first active magnet ring 21 will move away from the first driven magnet ring 24. The first transmission unit loses its power source, and the second active magnet ring 10 will move closer to the second driven magnet ring 08. Once the distance between them reaches the sensing distance, the second active magnet ring 10... This will cause the second driven magnet ring 08 to rotate, which in turn will cause the second transmission part to rotate eccentrically, thereby changing the volume of the second pressurizing chamber 62. When the volume increases, the residual water in the water outlet pipe 84 and nozzle 85 is sucked into the second pressurizing chamber 62 through the water outlet 56, and then pumped to the second water outlet chamber 55 and the third water outlet chamber 53. Then, the water control component controls the water circuit at the second water sealing ring 41 to be connected, and then pumped to the water inlet 31 and transported back to the water tank 81, realizing reverse water pumping. This invention can achieve the effect of bidirectional water pumping. The integrated suction and discharge pump 83 has the dual functions of water suction and water pumping. After its application in the air fryer system, it can pump the residual water in the water outlet pipe 84 and nozzle 85 back to the water tank 81 after the food is baked, avoiding residual water droplets falling on the baked food and effectively ensuring the taste of the baked food.
