Description
Technical Field
[0001] This utility model relates to the field of shock-absorbing and sealing structure technology, and more specifically, to an automatic compensation shock-absorbing and sealing structure for an air purifier. Background Technology
[0002] With the widespread use of air purifiers in various enclosed spaces such as homes, offices, and vehicles, users are increasingly demanding more and more from them in terms of purification efficiency stability, quiet operation, and long-term reliability. However, traditional air purifiers are mostly fixed and integrated, which cannot dynamically cope with fan vibration, component thermal expansion and contraction, and installation gaps caused by long-term wear and tear during equipment operation. This can easily lead to sealing failure, resulting in air leakage after purification or the infiltration of external pollutants, directly reducing the purification effect. The existing publication number CN205876298U discloses a sealing and vibration damping structure for components under high temperature and high pressure environments, transforming a non-magnetic drill collar into a cylindrical structure. Through calculation and simulation, a series of standardized cylindrical structure designs were developed for drill collars of different sizes, ensuring maximum installation space for sensors and circuits while optimizing the mechanical performance of the drill collar. A dual vibration damping method, employing a vibration-damping encapsulation process to package the circuit (sensor) and the vibration-damping frame, ensures reliable operation of the circuit and sensor under extreme vibration and shock environments. The proposed cylindrical sealing and vibration damping structure provides a modular approach to drill collar design, significantly shortening the product design cycle and improving the reliability and success rate of new products. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: Traditional shock-absorbing and sealing structures mostly adopt a fixed integrated connection structure, lacking an upper and lower split pressure adjustment mechanism. During operation, the installation gap caused by vibration and component wear can easily lead to air leakage due to poor sealing surface fit. In addition, the fixed connection directly transmits the vibration of core components such as the fan, causing structural resonance. After long-term use, the sealing and shock absorption performance will continue to decline as the gap increases and the components age. Therefore, an automatic compensation and shock absorption sealing structure for air purifiers is proposed to address the above problems. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic compensation and shock absorption sealing structure for an air purifier to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic compensation and shock absorption sealing structure for an air purifier, comprising an upper shell, a lower shell mechanism, a fan body, and a connecting component. The lower shell mechanism is installed below the upper shell, and the connecting component is installed above the inner wall of the lower shell mechanism. The fan body is installed above the connecting component, and the lower shell mechanism includes a main body component and a sound insulation component. The sound insulation component is installed on the side of the main body component.
[0005] Preferably, the main component includes a main support steel bar, a secondary support steel bar, and a caster wheel, with the main support steel bar installed above the caster wheel and the secondary support steel bar installed on the side of the main support steel bar.
[0006] Preferably, the sound insulation component includes a sealing sponge pad, sound-absorbing cotton, and a sealing steel plate, wherein the sealing sponge pad is installed on the side of the sealing steel plate, and the sound-absorbing cotton is installed on the side of the sealing sponge pad away from the sealing steel plate.
[0007] Preferably, the upper housing includes a baffle, a protective bracket, and a protective pad, and the protective pad is installed on the upper part of the inner wall of the protective bracket, and the baffle is installed on the upper part of the protective pad.
[0008] Preferably, the connecting assembly includes a fan damping pad, a clamping threaded rod, and a clamping adjusting nut, and the clamping threaded rod is installed above the fan damping pad, and the clamping adjusting nut is installed on the outer diameter surface of the clamping threaded rod.
[0009] Preferably, the main support steel bar and the secondary support steel bar are connected by welding, and the main support steel bar and the caster wheel are connected by bolts, and two sets of secondary support steel bars are provided.
[0010] Preferably, the sealing steel plate and the sealing sponge pad are bonded together, and the sealing sponge pad and the sound-absorbing cotton are bonded together, and the sealing steel plate is provided in five sets.
[0011] Preferably, the fan vibration damping pad and the clamping threaded rod are connected by threads, and the clamping threaded rod and the clamping adjusting nut are connected by threads, and four sets of clamping threaded rods are provided.
[0012] The technical effects and advantages of this utility model are as follows: 1. Compared with the prior art, the automatic compensation and shock absorption sealing structure of the air purifier is based on the split structure of the upper shell and the lower shell mechanism. It relies on the clamping threaded rod, the clamping adjusting nut and the fan shock absorption pad of the connecting component to form a downward clamping system. By rotating the clamping adjusting nut, the stroke of the clamping threaded rod can be changed, thereby adjusting the clamping force on the fan body and the compression of the fan shock absorption pad, and dynamically compensating for the displacement changes caused by vibration during equipment operation.
[0013] 2. Compared with the existing technology, the automatic compensation and shock absorption sealing structure of this air purifier directly wraps the bottom of the fan body with an elastic material through the fan shock absorption pad of the connecting component, which absorbs the vibration energy generated by the operation of the fan and reduces the transmission of vibration to the main support steel bar and the lower shell mechanism, thereby weakening the noise caused by structural vibration from the source. Secondly, the sealing steel plate of the sound insulation component on the side of the lower shell mechanism acts as a rigid barrier to block noise penetration, and the sealing sponge pad fills the gaps with elasticity to prevent airflow noise from leaking out of the gaps. The sound-absorbing cotton, relying on its porous structure, absorbs and attenuates the high-frequency noise generated by airflow and component friction in the cavity. Attached Figure Description

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1 As attached Figures 1 to 4The air purifier automatic compensation shock absorption sealing structure shown includes an upper shell 1, a lower shell mechanism 2, a fan body 3, and a connecting component 4. The lower shell mechanism 2 is installed below the upper shell 1, the connecting component 4 is installed on the upper inner wall of the lower shell mechanism 2, the fan body 3 is installed above the connecting component 4, the lower shell mechanism 2 includes a main body component 5 and a sound insulation component 6, and the sound insulation component 6 is installed on the side of the main body component 5.
[0021] Among them: when the upper shell 1 and the lower shell mechanism 2 form the main frame of the air purifier through the layered design, the connecting component 4 connects the fan body 3 and the lower shell mechanism 2, and at the same time serves as a shock-absorbing and sealing connecting carrier; the main component 5 of the lower shell mechanism 2 undertakes the structural support function, and the sound insulation component 6 is wrapped around the side of the main component 5 to absorb the noise generated by the fan body 3 during operation.
[0022] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, the main component 5 includes a main support steel bar 7, a secondary support steel bar 8, and casters 9. The main support steel bar 7 is installed above the casters 9, and the secondary support steel bar 8 is installed on the side of the main support steel bar 7. The main support steel bar 7 serves as the core load-bearing component. The secondary support steel bar 8 is welded to strengthen the lateral structural strength, forming a stable support frame. The casters 9 are connected to the main support steel bar 7 by bolts. The rigid support of the steel bar enables convenient movement of the equipment and provides stable support for the upper structure.
[0023] In a preferred embodiment, the sound insulation component 6 includes a sealing sponge pad 10, a sound-absorbing cotton 11, and a sealing steel plate 12. The sealing sponge pad 10 is installed on the side of the sealing steel plate 12, and the sound-absorbing cotton 11 is installed on the side of the sealing sponge pad 10 away from the sealing steel plate 12. The sealing steel plate 12 serves as a rigid base layer to provide an initial sealing surface and structural support. The sealed sponge pad 10, through its elastic deformation, fills the gaps to achieve physical sealing. The sound-absorbing cotton 11, relying on its porous structure, absorbs noise generated by airflow and structural vibration.
[0024] In a preferred embodiment, the upper housing 1 includes a baffle 13, a protective bracket 14, and a protective pad 15. The protective pad 15 is installed on the upper inner wall of the protective bracket 14, and the baffle 13 is installed on the upper protective pad 15. The protective bracket 14 provides rigid structural support for the upper housing 1. The protective pad 15 uses a buffer material to absorb external pressure or vibration, reducing the vibration transmitted to the upper housing 1. The baffle 13 further seals the space above the protective pad 15, preventing dust and debris from entering the interior of the lower housing mechanism 2 through the gap connecting the upper housing 1 and the lower housing mechanism 2.
[0025] In a preferred embodiment, the connecting assembly 4 includes a fan damping pad 16, a clamping threaded rod 17, and a clamping adjusting nut 18. The clamping threaded rod 17 is installed above the fan damping pad 16, and the clamping adjusting nut 18 is installed on the outer diameter surface of the clamping threaded rod 17. The fan damping pad 16 absorbs the vibration generated by the operation of the fan with an elastic material to achieve vibration isolation. The clamping threaded rod 17 is engaged with the fan damping pad 16 and the clamping adjusting nut 18 through threads. Rotating the adjusting nut can change the clamping stroke of the threaded rod, thereby adjusting the clamping force on the fan and the compression of the damping pad, and dynamically optimizing the damping and sealing pressure.
[0026] In a preferred embodiment, the main support steel bar 7 and the secondary support steel bar 8 are connected by welding, the main support steel bar 7 and the caster wheel 9 are connected by bolts, and two sets of secondary support steel bars 8 are provided.
[0027] In a preferred embodiment, the sealing steel plate 12 and the sealing sponge pad 10 are bonded together, the sealing sponge pad 10 and the sound-absorbing cotton 11 are bonded together, and the sealing steel plate 12 is provided with five sets.
[0028] In a preferred embodiment, the fan damping pad 16 and the clamping threaded rod 17 are connected by threads, and the clamping threaded rod 17 and the clamping adjusting nut 18 are connected by threads. The clamping threaded rod 17 is provided in four sets.
[0029] The working process of this utility model is as follows: First, the equipment achieves shock absorption and noise reduction through the coordinated action of multiple components. The upper shell 1 and the lower shell mechanism 2 form an overall frame. The main component 5 in the lower shell mechanism 2 is the core support, and the main support steel bar 7 is the load-bearing core. The lateral strength is strengthened by welding the secondary support steel bar 8. The caster wheel 9 is connected to the main support steel bar 7 by bolts, which not only ensures the stability of the overall structure but also enables the flexible movement of the equipment. The fan body 3 is installed on the upper inner wall of the lower shell mechanism 2 through the connecting component 4. In the connecting component 4, the fan shock absorption pad 16 directly absorbs the vibration generated by the operation of the fan body 3 with elastic material, realizing vibration isolation. At the same time, the pressing threaded rod 17 is connected to the fan shock absorption pad 16 and the pressing adjustment nut 18 through threads. Rotating the pressing adjustment nut 18 can change the pressing stroke of the threaded rod, dynamically adjusting the pressing force on the fan body 3 and the compression of the fan shock absorption pad 16, thereby automatically compensating for the displacement changes caused by installation gaps or vibrations, and completing automatic compensation and shock absorption.
[0030] Furthermore, in the sound insulation component 6 of the lower housing mechanism 2, the sealing steel plate 12 serves as a rigid base layer to provide an initial sealing surface, and the sealing sponge pad 10 bonded to its side uses elastic deformation to fill the gaps. The protective bracket 14 inside the upper housing 1 provides rigid support for the structure, and the protective pad 15 weakens external pressure and vibration transmission through the buffer material. The baffle 13 above further blocks dust and debris from entering from the gap between the upper housing 1 and the lower housing mechanism 2. Noise reduction is achieved by the sound-absorbing cotton 11 of the sound insulation component 6 relying on its porous structure to absorb the noise generated by the fan operation, air flow, and structural vibration. At the same time, the fan vibration damping pad 16 reduces the transmission of vibration to the housing, avoiding additional noise caused by vibration. The above is the working principle of this automatic compensation vibration damping sealing structure of an air purifier.
