Description

Technical Field

[0001] This invention relates to the field of fiber filter technology, specifically to a multilayer nanofiber filter structure. Background Technology

[0002] Nanofiber filters are a type of high-efficiency filtration material composed of ultrafine fibers with diameters ranging from tens to hundreds of nanometers. Their dense fiber structure and high porosity effectively intercept tiny particles, bacteria, and viruses while maintaining low airflow resistance. Their advantages lie in high filtration efficiency, lightweight design, and customizability, making them an important area of ​​development in current filtration technology.

[0003] Existing multilayer nanofiber filters typically consist of an outer nanofiber filter cartridge and an inner nanofiber filter cartridge. However, the outer and inner nanofiber filter cartridges are mostly fixedly installed, which is inconvenient for disassembly and installation. This makes subsequent cleaning of the outer and inner nanofiber filter cartridges difficult and affects the filtration effect of the nanofiber filter. Therefore, based on actual usage, we have improved the above-mentioned existing technology. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-layer nanofiber filter structure includes an outer nanofiber filter cartridge and an inner nanofiber filter cartridge. Mounting seats are connected to the top of both side walls of the outer nanofiber filter cartridge, and a through hole communicating with the mounting seat is formed on the outer nanofiber filter cartridge. Connecting grooves communicating with the through hole are formed on the top of both side walls of the inner nanofiber filter cartridge. An operating rod is slidably connected inside the mounting seat. A sliding plate is mounted on the outer wall of the operating rod, and a connecting strip adapted to the connecting groove is connected to the end of the operating rod near the inner nanofiber filter cartridge. A limiting component for limiting the sliding plate is provided on the front end face of the mounting seat.

[0008] Furthermore, the outer wall of the control lever is fitted with a compression spring, which is located between the outer side of the slide plate and the inner wall of the mounting base.

[0009] Furthermore: Side guide grooves are provided on both inner walls of the mounting base, and sliders are slidably connected in both sets of side guide grooves, with the sliding plate located between adjacent sliders.

[0010] Furthermore: the limiting component includes a fixed cylinder mounted on the front end face of the mounting base, and a pin is slidably connected inside the fixed cylinder, and a socket for connecting the pin is provided on the front slider.

[0011] Furthermore: the outer nanofilter cartridge has two sets of slots, and the outer wall of the inner nanofilter cartridge is connected to two sets of blocks that are compatible with the slots.

[0012] Furthermore: a pull ring is installed at the end of the operating lever away from the connecting bar, and the handheld end of the pull ring is covered with an anti-slip rubber sleeve.

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

[0014] This invention allows the sliding plate to move by pulling the operating rod inside the mounting base. Combined with the elasticity of the compression spring, the connecting strip can be connected or disconnected from the connecting groove on the outer wall of the inner nanofiber filter cartridge, realizing quick assembly and disassembly of the outer and inner nanofiber filter cartridges and facilitating the assembly and disassembly of the multi-layer nanofiber filter structure. By sliding the pin inside the fixing cylinder, it can be connected to the insertion hole on the front slider. When the connecting strip is installed in the connecting groove, it can reinforce the position of the sliding plate, thereby limiting the position of the connecting strip and improving the stability of the installation of the outer and inner nanofiber filter cartridges.

[0027] Example 1:

[0028] Please see Figure 1This utility model provides a technical solution: a multi-layer nanofiber filter structure, including an outer nanofiber filter cylinder 1 and an inner nanofiber filter cylinder 2. The top of both sides of the outer nanofiber filter cylinder 1 are connected to mounting bases 3, and the outer nanofiber filter cylinder 1 has through holes 11 communicating with the mounting bases 3. The top of both sides of the inner nanofiber filter cylinder 2 are provided with connecting grooves 6 communicating with the through holes 11. An operating rod 7 is slidably connected inside the mounting base 3. A sliding plate 8 is installed on the outer wall of the operating rod 7, and a connecting strip 10 adapted to the connecting groove 6 is connected to the end of the operating rod 7 near the inner nanofiber filter cylinder 2. The front end face of the mounting base 3 is provided with a limiting component for limiting the sliding plate 8.

[0029] The mounting base 3 is fixedly connected to the outer nanofiber filter cartridge 1, and the operating rod 7 is fixedly connected to the connecting strip 10. The inner nanofiber filter cartridge 2 is installed inside the outer nanofiber filter cartridge 1. By pulling the operating rod 7 inside the mounting base 3, the connecting strip 10 can be connected to or disconnected from the connecting groove 6 opened on the outer wall of the inner nanofiber filter cartridge 2, realizing the quick assembly and disassembly of the outer nanofiber filter cartridge 1 and the inner nanofiber filter cartridge 2, which facilitates the assembly and disassembly of the multi-layer nanofiber filter structure. When the connecting strip 10 is installed in the connecting groove 6, the position of the sliding plate 8 can be reinforced by the limiting component, that is, the position of the connecting strip 10 is limited, which improves the stability of the installation of the outer nanofiber filter cartridge 1 and the inner nanofiber filter cartridge 2.

[0030] Preferably, the outer wall of the operating rod 7 is fitted with a compression spring 9, which is located between the outer side of the slide plate 8 and the inner wall of the mounting base 3. When the inner nano-filter cartridge 2 is installed inside the outer nano-filter cartridge 1, the operating rod 7 is pulled outward, and the slide plate 8 moves outward. The compression spring 9 is in a compressed state. When the inner nano-filter cartridge 2 is installed inside the outer nano-filter cartridge 1, the connecting groove 6 is aligned with the through hole 11. The operating rod 7 is released, and the compressed spring 9 automatically returns to its original position. The slide plate 8 moves towards the inner nano-filter cartridge 2, so that the connecting strip 10 is connected to the connecting groove 6 through the through hole 11, thus completing the installation of the inner nano-filter cartridge 2 and the outer nano-filter cartridge 1.

[0031] Preferably, the inner walls on both sides of the mounting base 3 are provided with side guide grooves 12, and sliders 13 are slidably connected in both sets of side guide grooves 12. The slide plate 8 is located between adjacent sliders 13. Through the sliding connection between the side guide grooves 12 and the sliders 13, the movement of the slide plate 8 is guided and limited.

[0032] Preferably, the limiting component includes a fixed cylinder 15 installed on the front end face of the mounting base 3, and a pin 16 is slidably connected inside the fixed cylinder 15. The front slider 13 has an insertion hole 14 for connecting with the pin 16. When the connecting strip 10 is installed in the connecting groove 6, the insertion hole 14 on the slider 13 is aligned with the through hole in the fixed cylinder 15. The pin 16 moves to connect with the insertion hole 14, which fixes the position of the front slider 13, fixes the position of the slide plate 8, and limits the position of the connecting strip 10, thereby improving the stability of the installation of the outer nano-filter cylinder 1 and the inner nano-filter cylinder 2.

[0033] Preferably, the outer nanofilter cartridge 1 has two sets of slots 4, and the outer wall of the inner nanofilter cartridge 2 is connected to two sets of blocks 5 that are compatible with the slots 4; the blocks 5 are fixedly connected to the inner nanofilter cartridge 2, and the connection between the blocks 5 and the slots 4 plays a limiting role in the installation of the outer nanofilter cartridge 1 and the inner nanofilter cartridge 2.

[0034] Example 2:

[0035] Reference Figure 3 The difference between this embodiment and the first embodiment is that: a pull ring is installed at the end of the operating lever 7 away from the connecting bar 10, and the hand-held end of the pull ring is covered with an anti-slip rubber sleeve; the pull ring facilitates the movement of the operating lever 7, and the anti-slip rubber sleeve plays an anti-slip role, preventing the hand from slipping off when holding the pull ring.

[0036] It should be noted that the electrical component of this utility model is used to organize the wire harness during operation, and will not cause the wire harness to become tangled.

[0037] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
