Description

Technical Field

[0001] This utility model relates to the field of smoke purifier technology, and in particular to a structure for sealing a smoke purifier filter element. Background Technology

[0002] Smoke purifiers are used to purify smoke in various environments to improve local air quality. The filter element inside the smoke purifier needs to be sealed. Some existing devices use screws to hold the filter element in place, which is not very convenient. Others place the filter element directly on top of the air vent, relying on its own weight for sealing. This weight-based sealing method is not very effective and may shift, causing polluted gas to be discharged without treatment. Chinese patent CN211159032U discloses a top-plate type lifting mechanism for the main filter of a smoke purifier, including a purifier cabinet and a lifting structure. Two crossbeams are positioned in the middle of the interior of the purifier cabinet, corresponding to the front and rear ends of the cabinet. The lifting structure is mounted on the crossbeams. The main filter is housed within the purifier cabinet above the crossbeams. The lifting structure includes a U-shaped top plate, a grooved rod, and a crank handle. The grooved rod is positioned in the middle of the two crossbeams, with both ends rotatably connected to the two crossbeams. The U-shaped top plate is located in the middle of the upper part of the two crossbeams, and top grooves are formed on both sides of the grooved rod. This invention solves the problem of existing technologies failing to achieve a good seal between the main filter and the machine body by incorporating a lifting structure, a sponge sealing strip, and a guide rail.

[0003] The aforementioned patent uses a groove to lift the U-shaped top plate during use. However, the contact between the groove and the U-shaped top plate during rotation is not smooth enough, which can easily lead to jamming and over-rotation. Therefore, in view of the above situation, there is an urgent need to develop a handle that rotates 90° to seal, which can not only seal the surface but also prevent the filter element from slipping when the device is tilted. The internal limiting plate limits the eccentric wheel, which can prevent it from sliding back and forth and also prevent the handle from falling downwards. The eccentric wheel has a right angle on one side and a rounded corner on the other. The rounded corner can smoothly lift the object, while the right angle can prevent the handle from rotating excessively and affecting the sealing structure of the smoke purifier filter element, so as to overcome the shortcomings of the current practical application and meet the current needs. Utility Model Content

[0004] The purpose of this invention is to provide a sealing structure for a smoke purifier filter element to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A structure for sealing a smoke purifier filter element includes a housing, a door, a primary filter element, load-bearing beams, a lifting mechanism, a secondary filter element, a sealing top cover, a sealing strip, and filter element sliding guide rails. One end of the door is rotatably connected to the housing via a hinge, and the other end is fixed to the housing via screws. The primary filter element is installed inside the lower part of the housing. Two load-bearing beams are fixed above the primary filter element inside the housing, and two filter element sliding guide rails are fixed on the load-bearing beams. The secondary filter element is slidably installed between the two filter element sliding guide rails. The lifting mechanism is installed between the two load-bearing beams and is used to control the vertical displacement of the secondary filter element. The lifting mechanism includes: a rotating shaft, a handle, a lifting platform, eccentric wheels, thickened fixing plates, and a limiting plate. There are two thickened fixing plates, each fixed within a load-bearing crossbeam. The rotating shaft is rotatably connected to the two thickened fixing plates via bearings. A handle is fixed to one end of the rotating shaft, and a nylon protective sleeve is fixed to the outside of the handle. Two eccentric wheels are fixed on the rotating shaft, and a lifting platform is provided on the upper side of each eccentric wheel. Each lifting platform is slidably mounted on a load-bearing crossbeam. The top half of each eccentric wheel is rounded, and the other half is right-angled. The limiting plate is fixed within the load-bearing crossbeam.

[0007] Preferably, the lifting platform is provided with a U-shaped groove.

[0008] Preferably, an air inlet is provided at the lower side of the chassis, and an air outlet is provided at the upper rear of the chassis.

[0009] Preferably, a sealing top cover is fixed to the upper side of the secondary filter element inside the casing, a sealing strip is fixed to the lower side of the sealing top cover, and an air vent is provided on the sealing top cover.

[0010] Preferably, a limit baffle is fixed on the inner side of the door, and the limit baffle is used to block the handle.

[0011] The beneficial effects of this utility model are as follows: The sealed structure of the smoke purifier filter element allows for easy operation. When the user rotates the handle, the handle drives the rotating shaft and eccentric wheel to rotate. As the eccentric wheel rotates upwards, its rounded corner contacts the lifting platform first, making the lifting process smoother. Once the eccentric wheel is fully rotated, its right angle contacts the lifting platform, providing greater friction and preventing excessive rotation by the user. After full rotation, the handle is in a vertical position. During the upward movement of the lifting platform, the secondary filter element is lifted upwards, ensuring a tight seal between the upper end of the secondary filter element and the sealing strip, thus achieving a seal. Then, close the door and use the limiting baffle to block one side of the handle, preventing it from rotating back to its original position due to vibration or other external interference. During purification, the flue gas enters through the inlet, passes through the primary filter, then the secondary filter, and finally exits through the outlet at the top of the sealed top cover, exiting from the back of the casing. When the handle is rotated from a vertical to a horizontal position, the eccentric wheel enters the limiting plate. The limiting plate prevents the eccentric wheel from shifting forward or backward and also prevents accidental downward rotation of the handle and eccentric wheel by the user. The lifting platform slides back to its original position under the weight of the secondary filter. In summary, this utility model seals the handle by rotating it 90°, which not only seals the surface but also prevents the filter from slipping when the equipment is tilted. The internal limiting plate limits the eccentric wheel, preventing forward or backward sliding and preventing the handle from falling downward. The eccentric wheel has a right angle on one side and a rounded corner on the other. The rounded corner smoothly lifts objects, while the right angle prevents the handle from rotating excessively and affecting the seal. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] See Figures 1-9 In this embodiment of the present invention, a structure for sealing a filter element in a smoke purifier includes a housing 1, a door 2, a primary filter element 4, a load-bearing crossbeam 5, a lifting mechanism 6, a secondary filter element 7, a sealing top cover 8, a sealing strip 9, and filter element sliding guide rails 10. An air inlet 101 is provided at the lower side of the housing 1, and an air outlet 101 is provided at the upper back of the housing 1. One end of the door 2 is rotatably connected to the housing 1 via a hinge, and the other end is fixed to the housing 1 via screws. The primary filter element 4 is installed inside the lower part of the housing 1. Two load-bearing crossbeams 5 are fixed above the primary filter element 4 inside the housing 1, and two filter element sliding guide rails 10 are fixed on the load-bearing crossbeams 5. The primary filter element 7 is slidably installed between two filter element sliding guide rails 10. The two filter element sliding guide rails 10 limit the left and right positions of the secondary filter element 7. A baffle is fixed at the rear end of the filter element sliding guide rail 10 so that the secondary filter element 7 will be blocked by the baffle after sliding into position within the filter element sliding guide rail 10. The lifting mechanism 6 is installed between two load-bearing crossbeams 5. The lifting mechanism 6 is used to control the up and down displacement of the secondary filter element 7. A sealing top cover 8 is fixed to the upper side of the secondary filter element 7 inside the housing 1. A sealing strip 9 is fixed to the lower side of the sealing top cover 8. An air outlet is provided on the sealing top cover 8 so that the flue gas in the secondary filter element 7 can be discharged through the air outlet.

[0026] The lifting mechanism 6 includes: a rotating shaft 601, a handle 602, a lifting platform 603, eccentric wheels 604, thickened fixing plates 605, and a limiting plate 606. There are two thickened fixing plates 605, each fixed within one of the two load-bearing beams 5. The rotating shaft 601 is rotatably connected to the two thickened fixing plates 605 via bearings. A handle 602 is fixed to one end of the rotating shaft 601, and a nylon protective sleeve is fixed to the outside of the handle 602. When the handle 602 is rotated to a vertical position, it is in the lifting state. Two eccentric wheels 604 are fixed on the rotating shaft 601. A lifting platform 603 is provided on the upper side of each eccentric wheel 604. Each lifting platform 603 is slidably mounted on a load-bearing beam 5. The top half of the eccentric wheel 604 is rounded (6041) and the other half is right-angled (6042). When rotating upwards, the rounded corner 6041 contacts the lifting platform 603 first, making the lifting process smoother. After the eccentric wheel 604 rotates to its position, the right angle 6042 contacts the lifting platform 603. The contact between the right angle 6042 and the lifting platform 603 provides greater friction, preventing the user from rotating excessively. The limiting plate 606 is fixed inside the load-bearing crossbeam 5. When the eccentric wheel 604 is rotated into the limiting plate 606, it will be limited by the limiting plate 606, which can prevent the eccentric wheel 604 from shifting back and forth, and can also prevent the user from continuing to rotate the handle 602 and the eccentric wheel 604 downwards by mistake. The lifting platform 603 is provided with a U-shaped groove 6031. The design of the U-shaped groove 6031 can prevent the secondary filter element 7 from shifting and becoming unsealed due to the lateral pushing force during the upward movement of the secondary filter element 7 caused by the rotation of the handle 602.

[0027] A limit stop 3 is fixed on the inside of the door 2. The limit stop 3 is used to block the handle 602. When the handle 602 is rotated to the vertical position, the door 2 is closed. The limit stop 3 blocks one side of the handle 602 to prevent the handle 602 from rotating back due to vibration or other external factors.

[0028] Working Principle: The smoke purifier features a sealed filter element structure. During use, the user manually rotates the handle 602, which in turn rotates the shaft 601 and the eccentric wheel 604. When the eccentric wheel 604 rotates upwards, the rounded corner 6041 contacts the lifting platform 603 first, making the lifting process smoother. Once the eccentric wheel 604 has rotated to its final position, the right angle 6042 contacts the lifting platform 603. This contact provides greater friction, preventing excessive rotation by the user. After rotation, the handle 602 is in a vertical position. As the lifting platform 603 rises, it lifts the secondary filter element 7 upwards, ensuring a tight seal between the upper end of the secondary filter element 7 and the sealing strip 9, thus achieving a seal. Then, close the door 2 and block one side of the handle 602 with the limit baffle 3 to prevent the handle 602 from rotating back due to vibration or other external factors. During purification, the flue gas enters from the air inlet 101, passes through the primary filter element 4, then through the secondary filter element 7, and then exits from the air outlet at the top of the sealed top cover 8 and finally exits from the back of the casing 1. When the handle 602 is rotated from the vertical position to the horizontal position, the eccentric wheel 604 enters the limit plate 606. The limit plate 606 can prevent the eccentric wheel 604 from moving back and forth and can also prevent the user from continuing to rotate the handle 602 and the eccentric wheel 604 downwards by mistake. The lifting platform 603 slides down and returns to its original position under the gravity of the secondary filter element 7.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
