Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a sheet metal filtering slideway. Background Art

[0002] As people's demand for air quality increases, many families install high-efficiency filters in their rooms to purify the air entering the room. To ensure the purification effect of the filter, the filter needs to be removed from the installation slide regularly for maintenance. However, due to the limitation of the manufacturing process, there is a certain distance between the installation slide and the filter. The high-efficiency filter is equipped with multiple filter structures to purify the air, so the resistance of air circulation here is less than that of the high-efficiency filter. Therefore, when the equipment is used, some unpurified air will flow directly into the room from the gap, resulting in the indoor air not reaching the proper purification level, reducing the effect of the high-efficiency filter. In view of this, we propose a sheet metal filter slide. Utility Model Content

[0003] The utility model aims to solve the defect that the unpurified air from the outside easily enters the room from the assembly gap when the existing high-efficiency filter is in use, and proposes a sheet metal filtering slideway.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A sheet metal filtering slideway comprises a slideway and a high-efficiency filter slidably mounted on the inner side of the slideway, wherein a sealing component for isolating an assembly gap between the slideway and the high-efficiency filter is provided inside the slideway;

[0006] The sealing assembly includes mounting protrusions fixedly mounted at both ends of the slideway, an extrusion plate is rotatably mounted between the two mounting protrusions, a sealing strip is slidably mounted between the extrusion plate and the slideway, and one end of the sealing strip is in contact with the high-efficiency filter, and a driving assembly for driving the extrusion plate to rotate is provided in the mounting protrusion.

[0007] Preferably, the driving assembly includes a driving screw threadedly installed inside the mounting protrusion, one end of the driving screw slidingly extends to the outside of the mounting protrusion and is coaxially fixed with a driving end, and the other end is coaxially fixed with a guide block, and the rotating end of the extrusion plate is provided with a guide groove for the guide block to slide.

[0008] Preferably, the cross sections of the guide block and the guide groove are both cross-shaped.

[0009] Preferably, the cross section of the sealing strip is V-shaped.

[0010] Preferably, the contact end of the sealing strip and the high efficiency filter is configured to be in an arc shape.

[0011] Preferably, the slideway is provided with friction-reducing balls in contact with the high-efficiency filter.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model achieves the effect of isolating the assembly gap between the high-efficiency filter and the slideway by setting the sealing component, preventing the outside air from entering the room from there, improving the air purification quality, and under the setting of the extrusion plate, the sealing strip can still fit closely with the high-efficiency filter when it is worn, further improving the isolation effect of the sealing strip.

[0014] 2. The utility model increases the contact area between the sealing strip and the high-efficiency filter by setting the arc-shaped contact end of the sealing strip, thereby improving the fit between the sealing strip and the high-efficiency filter.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] People have higher and higher requirements for indoor air quality. To meet the demand, many people will install high-efficiency filters indoors to allow air to pass through the high-efficiency filters before entering the room. However, due to the limitations of the manufacturing process, a lot of air will bypass the high-efficiency filters and enter the room from the gaps when the high-efficiency filters are used, thereby reducing the indoor air quality. In order to solve the above defects, improve indoor air quality, and meet people's demand for indoor air quality, we propose the following solutions.

[0023] Embodiment 1

[0024] Since the unpurified air from the outside can easily enter the room through the assembly gap, refer to Figure 1-Figure 5 The present embodiment proposes a sheet metal filter slideway, which achieves the effect of isolating the assembly gap between the high-efficiency filter and the slideway, preventing outside air from entering the room from here, and improving the air purification quality. It is mainly composed of a slideway 1 and a high-efficiency filter 2 slidably installed on the inner side of the slideway 1. A sealing component 3 is provided inside the slideway 1 for isolating the assembly gap between the slideway 1 and the high-efficiency filter 2. When the high-efficiency filter 2 is installed, the slideway 1 can be installed in a fixed position first, and then the high-efficiency filter 2 can be installed on the slideway 1. Then, the assembly gap between the high-efficiency filter 2 and the slideway 1 is isolated by the sealing component 3 to prevent outside air from entering the room from here, thereby improving the air purification effect.

[0025] In order to facilitate the inspection and maintenance of the high-efficiency filter 2, an installation slide is generally provided between the high-efficiency filter 2 and the installation position. There are generally two types of installation slides on the market: foam slides, sheet metal or plastic slides. However, due to the limitations of the manufacturing process, there is a certain assembly gap between these slides 1 and the high-efficiency filter 2, but the size is different. Because the high-efficiency filter 2 is provided with multiple filtering structures to purify the air, the resistance to air circulation here is less than that of the high-efficiency filter 2. Therefore, when the equipment is in use, some unpurified air will flow directly into the room from the gap, resulting in the indoor air not being able to reach the desired purification level, reducing the effect of the high-efficiency filter 2. In order to solve the above-mentioned defects, in this embodiment, the sealing component 3 is provided to achieve the effect of isolating the assembly gap between the high-efficiency filter 2 and the slide 1, thereby ensuring the quality of the indoor air. The specific implementation method is as follows:

[0026] The sealing assembly 3 includes mounting protrusions 31 fixedly mounted at both ends of the slideway 1, an extrusion plate 32 is rotatably mounted between the two mounting protrusions 31, a sealing strip 33 is slidably mounted between the extrusion plate 32 and the slideway 1, and one end of the sealing strip 33 is in contact with the high-efficiency filter 2, and a driving assembly 34 for driving the extrusion plate 32 to rotate is provided in the mounting protrusion 31. After the high-efficiency filter 2 is installed, the sealing strip 33 can be inserted into the gap between the extrusion plate 32 and the slideway 1. At this time, one end of the sealing strip 33 is in contact with the high-efficiency filter 2, and the other end is in contact with the side wall of the slideway 1, thereby isolating the gap between the filter 2 and the slideway 1. The effect is to prevent outside air from entering the room without being filtered, thereby improving the quality of indoor air. Many similar products on the market also achieve the isolation effect by setting the sealing strip 33, but after repeated pulling of the high-efficiency filter 2, these sealing strips 33 will be worn, so that the fit with the high-efficiency filter 2 will become loose, resulting in a certain reduction in the isolation effect. The present embodiment can rotate and extrude the sealing strip 33 when the sealing strip 33 is not tightly fitted, thereby ensuring the tight fit between the sealing strip 33 and the high-efficiency filter 2, and further improving the isolation effect of the sealing strip 33.

[0027] The driving assembly 34 includes a driving screw rod 341 threadedly installed inside the mounting protrusion 31, one end of the driving screw rod 341 slides and extends to the outside of the mounting protrusion 31 and is coaxially fixed with a driving end 342, and the other end is coaxially fixed with a guide block 343, and the rotating end of the extrusion plate 32 is provided with a guide groove 344 for the guide block 343 to slide. When the extrusion plate 32 is rotated, the driving screw rod 341 can be rotated by rotating the driving end 342. Since the guide block 343 is coaxially fixed at one end of the driving screw rod 341, the extrusion plate 32 will be driven to rotate synchronously with the cooperation of the guide block 343 and the guide groove 344. At the same time, under the influence of the self-locking performance of the thread between the driving screw rod 341 and the mounting protrusion 31, the extrusion plate 32 will not loosen easily, thereby ensuring the stability of the extrusion plate 32 in extruding the sealing strip 33.

[0028] The cross-sections of the guide block 343 and the guide groove 344 are both set to be cross-shaped. The setting of the cross-shaped cross-section can optimize the force transmission path of the guide block 343, reduce energy loss, and achieve higher transmission efficiency. In addition, this design can effectively withstand forces and loads from different directions, making the mechanical transmission more stable and reliable.

[0029] Embodiment 2

[0030] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the shortcoming that when the existing high-efficiency filter 2 is in use, the unpurified air from the outside can easily enter the room through the assembly gap. However, the existing sealing strip 33 is mainly installed on the slide 1 through interference fit. In order to prevent it from falling off due to external forces such as vibration, many manufacturers will apply glue in the edging groove of the sealing strip 33 so that it can be firmly fixed on the slide 1. However, the sealing strip 33 has a service life. After a certain period of use, it will age and cannot fit the high-efficiency filter 2 well. At this time, it needs to be replaced, but the setting of glue will increase the difficulty of replacing the sealing strip 33.

[0031] Reference Figure 1-Figure 5 The cross section of the sealing strip 33 is V-shaped. In this embodiment, the special setting of the cross section of the sealing strip 33 makes the gap of the edge groove of the sealing strip 33 smaller and smaller. When the extrusion plate 32 is extruded, it can be firmly attached to the slide 1. When replacing, it is necessary to separate the extrusion plate 32 from the sealing strip 33, and the sealing strip 33 can be easily removed from the slide 1, thereby reducing the difficulty of replacing the sealing strip 33.

[0032] The contact end between the sealing strip 33 and the high efficiency filter 2 is configured to be arc-shaped. The configuration of the arc-shaped contact end increases the contact area between the sealing strip 33 and the high efficiency filter 2, thereby improving the degree of fit between the sealing strip 33 and the high efficiency filter 2.

[0033] The slide 1 is provided with anti-friction balls 4 in contact with the high-efficiency filter 2. The anti-friction balls 4 convert the sliding friction between the slide 1 and the high-efficiency filter 2 into rolling friction, thereby reducing the friction loss between the high-efficiency filter 2 and the slide 1 and extending the service life of the device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
