Description

Technical Field

[0001] This utility model relates to the field of oil fume purification technology, specifically to an oil fume purification kitchen device. Background Technology

[0002] Oil fume purification equipment is mainly used for the purification and treatment of oil fumes emitted at low altitudes in kitchens. In modern kitchens, almost every household has oil fume purification equipment installed, which can extract, transport and purify the oil fumes generated during kitchen use.

[0003] According to publicly available patent CN221197512U, a kitchen fume purification device includes a shell, a telescopic pipe fixedly connected to the bottom of the shell, an activated carbon layer and a fiber pad arranged sequentially from top to bottom inside the shell, and a gathering hood fixedly connected to the end of the telescopic pipe away from the shell. A cleaning brush is provided at the bottom of the fiber pad. When fumes enter the shell from the gathering hood, they blow against the buffer blades, causing a rotating shaft to rotate, achieving a buffering effect and preventing direct impact on the fiber pad and damage. The rotating shaft drives a gear to rotate, and a second gear engages, causing the second rotating shaft to rotate. The rotation of the second rotating shaft drives a half-gear to rotate, engaging with two racks. At this time, a rectangular frame moves back and forth, causing several cleaning brushes to clean the bottom of the fiber pad, thereby reducing the probability of fiber pad blockage. This solves the problem in the prior art where a large amount of continuous fumes impacting the fiber pad easily leads to blockage at the bottom, and in severe cases, the fume purification work cannot be achieved. In the process of realizing this utility model, the inventors discovered that the prior art has at least the following... The problem remains unresolved. While the surface of the fiber pad used for filtering oil fumes can be cleaned using a corresponding cleaning mechanism, in actual use, the aforementioned patent only uses a gathering hood at its bottom to collect and absorb external oil fumes. However, the amount of oil fumes produced varies depending on the usage conditions within the kitchen, and the range of fumes that the gathering hood can collect cannot be adjusted for suitability. Consequently, when the amount of oil fumes is excessive, the gathering hood cannot quickly extract and collect them, leading to the oil fumes still scattering and adversely affecting the kitchen environment and the health of the users. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a kitchen fume purification device to solve the technical problem that the amount of oil fume generated varies depending on the different usage conditions inside the kitchen, and the range of fume that the collecting hood can collect during absorption cannot be adjusted for applicability. As a result, when the amount of oil fume is too large, the collecting hood cannot quickly extract and collect the oil fume, which will still cause the oil fume to scatter and have an adverse effect on the kitchen environment and the health of the users.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design an oil fume purification kitchen device, including a first gas collection pipe, a second gas collection pipe is slidably inserted through both sides of the first gas collection pipe, a first air inlet groove is opened inside the side of the first gas collection pipe, a second air inlet groove is opened inside the side of the second gas collection pipe, and the number of the first air inlet groove and the second air inlet groove are the same.

[0006] A transmission plate is fixedly installed on the side of each second gas collecting pipe away from the first gas collecting pipe. A fixed frame is fixedly installed at the middle of the side of the first gas collecting pipe. A bidirectional synchronous drive mechanism is provided inside the fixed frame, and the bidirectional drive mechanism is connected to the transmission plate on the outside.

[0007] The fixed frame is equipped with a synchronization mechanism, which is connected to the bidirectional drive mechanism.

[0008] Preferably, the bidirectional drive mechanism includes a rotating lead screw, and rotating lead screws are rotatably mounted on both sides of the inside of the fixed frame via bearings. A transmission plate is movably sleeved on the outside of each rotating lead screw via a thread, and the transmission plate is movably mounted inside the fixed frame. The transmission plate has a thread inside that matches the outside of the rotating lead screw. A transmission block is fixedly mounted on both ends of the side of each transmission plate. Guide grooves are provided on both sides of the outside of the fixed frame, and the transmission blocks are slidably mounted inside the guide grooves.

[0009] Preferably, a transmission slide plate is slidably installed on both sides of the outer side of the fixed frame, and the side of the transmission block away from the transmission sleeve is fixedly connected to the outer side of the transmission slide plate. A push rod is fixedly installed on the outer side of each transmission slide plate, and the top edge of the push rod is fixedly connected to the outer side of the transmission plate.

[0010] Preferably, the synchronization mechanism includes a transmission bevel gear and a follower bevel gear. A rotating rod is rotatably mounted on the middle side of the fixed frame via a bearing. A transmission bevel gear is fixedly sleeved on the top side of the rotating rod. The transmission bevel gear is rotatably mounted inside the fixed frame. A follower bevel gear is fixedly sleeved on the side of each rotating screw away from the transmission plate, and the outer sides of the transmission bevel gear and the outer sides of the follower bevel gear mesh with each other. A servo motor is fixedly mounted on the middle side of the outer side of the fixed frame, and the side of the servo motor transmission shaft is fixedly connected to the top side of the rotating rod via a coupling.

[0011] Preferably, a support column is fixedly installed on the outer side of the top of the first gas collecting pipe, and a vacuum pump is fixedly installed on the top of the support column. There are four sets of support columns, which are located at the four corners of the bottom surface of the vacuum pump and installed on the upper side of the first gas collecting pipe. An air inlet pipe is vertically fixedly connected to the middle of the top of the first gas collecting pipe, and the air inlet pipe is connected to the air inlet at the bottom of the vacuum pump. An exhaust pipe is fixedly connected to the outer side of the top of the vacuum pump, and the exhaust pipe is fixedly connected to the exhaust port at the top of the vacuum pump.

[0012] Preferably, connecting plates are vertically fixedly installed on both sides of the outer side of the fixed frame, and an installation plate is movably installed on the outer side of each connecting plate. A fixed suction cup is fixedly installed on the side of each installation plate, and the number of fixed suction cups is several sets. An adjusting bolt is screwed to the middle of the side of each connecting plate, and the top of the side of the adjusting bolt is rotatably installed on the outer side of the installation plate through a bearing. A guide rod is fixedly installed on the top of the outer side of each installation plate, and the guide rod is slidably inserted into the top of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves slidingly connecting a second gas collecting pipe to both sides of the first gas collecting pipe, and connecting a transmission plate located at the side end of the second gas collecting pipe to a transmission sliding plate located outside the fixed frame via a push rod. When the servo motor rotates, driving the rotating rod and transmission bevel gear to rotate synchronously inside the fixed frame, the meshing transmission action of the transmission bevel gear and the follower bevel gear drives the rotating screws located on both sides of the fixed frame to rotate synchronously. Furthermore, the rotational transmission action of the rotating screws on the transmission plates causes the transmission plates on both sides of the fixed frame to move synchronously horizontally towards or relative to each other. The movement, coupled with the transmission action of the transmission block and the push rod, provides a corresponding horizontal pushing and pulling force to the second gas collecting pipe. This allows the two sets of second gas collecting pipes to move horizontally towards or relative to each other on both sides inside the first gas collecting pipe, adjusting the overall length of the first and second gas collecting pipes. This, in turn, changes the number of air inlet slots exposed to the outside of the first and second gas collecting pipes, thereby adjusting the suction range of the first and second gas collecting pipes. This allows the first and second gas collecting pipes to be adjusted according to the different amounts of oil fumes inside the kitchen, improving the efficiency of oil fume suction and purification inside the kitchen.

[0015] 2. This utility model features connecting plates at both ends of the rear side of the first gas collecting pipe, and fixed suction cups on the surface of the mounting plate on the outer side of the connecting plates. Combined with the tightening action of the adjusting bolts and the guiding and limiting action of the guide rod on the horizontal movement of the mounting plate, the mounting plate can drive the fixed suction cups to move horizontally back and forth synchronously on the outer side of the connecting plate. This allows the fixed suction cups to be pushed and firmly adhered to the kitchen wall, providing auxiliary installation and fixation for the overall suction and purification mechanism. This improves the stability of the overall mechanism when suctioning and transporting oil fumes, preventing arbitrary shaking of the entire mechanism when the air pump is running and suctioning oil fumes, which would affect the efficiency of oil fume suction and purification.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] Example 1: A kitchen fume purification device, see [link / reference] Figures 1 to 3A second gas collecting pipe 11 is slidably inserted through both sides of the first gas collecting pipe 1. A first air inlet groove 16 is formed inside the side of the first gas collecting pipe 1, and a second air inlet groove 17 is formed inside the side of the second gas collecting pipe 11. The number of first air inlet grooves 16 and second air inlet grooves 17 is the same. A support column 12 is fixedly installed on the outer side of the top of the first gas collecting pipe 1. A vacuum pump 13 is fixedly installed on the top of the support column 12. There are four sets of support columns 12, which are located at the four corners of the bottom surface of the vacuum pump 13 and installed on the upper outer side of the first gas collecting pipe 1. The first gas collection pipe 1 has an air inlet pipe 14 vertically fixedly connected to the middle of its top end, and the air inlet pipe 14 is connected to the air inlet at the bottom of the air pump 13. The air pump 13 has an exhaust pipe 15 fixedly connected to the outer side of its top, and the exhaust pipe 15 is fixedly connected to the exhaust port at the top of the air pump 13. Through the operation of the air pump 13 and the flow and transmission of the first air inlet groove 16 and the second air inlet groove 17 with the outside air, the outside air can be sucked up, thereby realizing the suction, transportation and purification of the oil fume inside the kitchen.

[0025] For details, see Figures 1 to 3 The fixed frame 2 has vertically fixed connecting plates 4 on both sides. Each connecting plate 4 has a movable mounting plate 42 on its outer side. Each mounting plate 42 has a fixed suction cup 41 fixedly installed on its side. There are several sets of fixed suction cups 41. Each connecting plate 4 has an adjusting bolt 43 screwed into the middle of its side by a thread. The top of the adjusting bolt 43 is rotatably mounted on the outside of the mounting plate 42 by a bearing. Each mounting plate 42 has a guide rod 44 fixedly installed on its top outer side. The guide rod 44 is slidably inserted into the top of the connecting plate 4. Under the structural action of the fixed suction cup 41 and the tightening action of the adjusting bolt 43, the fixed suction cup 41 can be squeezed and stably adsorbed onto the wall surface, thereby improving the stability of the overall mechanism during operation.

[0026] Further, see Figures 1 to 3Each second gas collecting pipe 11 has a transmission plate 21 fixedly installed on the side away from the first gas collecting pipe 1. A fixed frame 2 is fixedly installed at the middle of the side of the first gas collecting pipe 1. Rotating screws 24 are rotatably installed on both sides of the inside of the fixed frame 2 via bearings. The transmission plate 21 is movably sleeved on the outside of each rotating screw 24 via threads, and the transmission plate 21 is movably installed inside the fixed frame 2. The transmission plate 21 has threads inside that are adapted to the outside of the rotating screw 24. Transmission blocks 27 are fixedly installed at both ends of the side of each transmission plate 21. Guide grooves 31 are provided on both sides of the outside of the fixed frame 2. The transmission block 27 is slidably installed inside the guide groove 31. Transmission slide plates 28 are slidably installed on both sides of the fixed frame 2. The side of the transmission block 27 away from the transmission sleeve is fixedly connected to the outside of the transmission slide plate 28. A push rod 29 is fixedly installed on the outside of each transmission slide plate 28. The top edge of the push rod 29 is fixedly connected to the outside of the transmission plate 21. Under the rotational transmission action of the rotating screw 24 on the transmission plate 21 and under the connecting transmission action of the push rod 29, the power required for the second gas collecting pipe 11 to move horizontally inside the first gas collecting pipe 1 can be provided.

[0027] It is worth noting that, see Figures 1 to 3 The synchronization mechanism includes a transmission bevel gear 23 and a follower bevel gear 25. A rotating rod 22 is rotatably mounted on the middle side of the fixed frame 2 via a bearing. The top side of the rotating rod 22 is fixedly sleeved with the transmission bevel gear 23. The transmission bevel gear 23 is rotatably mounted inside the fixed frame 2. Each rotating screw 24 is fixedly sleeved with a follower bevel gear 25 on the side away from the transmission plate 21. The outer sides of the transmission bevel gear 23 and the follower bevel gear 25 mesh with each other. A servo motor 3 is fixedly mounted on the middle side of the outer side of the fixed frame 2. The side of the transmission shaft of the servo motor 3 is fixedly connected to the top side of the rotating rod 22 via a coupling. Under the meshing transmission action of the transmission bevel gear 23 and the follower bevel gear 25, the servo motor 3 can drive the two sets of rotating screws 24 to rotate synchronously when it is running, thereby driving the two sets of second gas collection pipes 11 to move horizontally synchronously inside the first gas collection pipe 1.

[0028] During operation, after connecting the exhaust pipe 15 and the corresponding fume filter mechanism, the adjusting bolt 43 is then tightened. Combined with the limiting sliding action of the guide rod 44 by the sliding groove inside the connecting plate 4, the mounting plate 42 can drive the fixed suction cup 41 to move horizontally on the outside of the connecting plate 4 until the fixed suction cup 41 adheres to the kitchen wall. The adjusting bolt 43 is then continuously tightened to press and fully adhere the fixed suction cup 41 to the wall surface. The suction pump 13 is then started, generating negative pressure suction through the first and second gas collection pipes 1 and 11 to extract and discharge the fumes generated by kitchen use. When the fume concentration is too high, the servo motor 3 is turned on via an external control switch, causing the rotating rod 22 and the transmission bevel gear 23 sleeved on its surface to rotate synchronously inside the fixed frame 2. The meshing transmission action of the transmission bevel gear 23 and the follower bevel gear 25 drives the rotating screw 24 located on both sides inside the fixed frame 2 to rotate synchronously. The rotation, combined with the rotational transmission of the screw 24 to the transmission plate 21 and the guiding and limiting effect of the guide groove 31 on the transmission block 27, allows the two sets of transmission plates 21 to move horizontally relative to each other within the fixed frame 2. Subsequently, under the connecting transmission action of the transmission block 27, the transmission slide plates 28 located on the upper and lower sides of the fixed frame 2 can move horizontally relative to each other synchronously. Combined with the connecting transmission action of the push rod 29, the horizontal movement force of the transmission slide plate 28 is converted into a horizontal pushing force on the transmission plate 21 and the second gas collection pipe 11, so that the second gas collection pipe 11 can move horizontally within the first gas collection pipe 1. While adjusting the number of the second air inlet slots 17 located outside the first gas collection pipe 11, until the first air inlet slot 16 and the second air inlet slots 17 located inside the first gas collection pipe 1 overlap and do not obstruct each other, the overall length of the first gas collection pipe 1 and the second gas collection pipe 11 is increased, and the suction range of external oil fumes is increased simultaneously, thereby improving the oil fume suction and purification efficiency inside the kitchen.
