Abstract
Description
Technical Field
[0001] This application relates to the field of curtain accessories technology, and in particular to a dustproof window covering. Background Technology
[0002] Roller blinds are a common light-blocking device widely used in various indoor light-blocking situations. Their basic structure includes a roller tube and a curtain body. The curtain body is raised and lowered by rotating the roller tube, and the roller tube is positioned and supported by a cover device.
[0003] In the application of existing roller blind covers, the surface of the roller blind closest to the outside of the window easily attracts a lot of dust, and the dust is rolled into the inside of the cover along with the roller blind. This not only makes cleaning inconvenient, but also increases friction between the curtain fabrics, causing blockages when opening and closing the blinds and affecting the smoothness of their use. Utility Model Content
[0004] In order to improve the technical problem of inconvenient cleaning of roller blind covers and increased friction between the curtain fabrics leading to blockage during opening and closing, this application provides a dustproof window cover.
[0005] The dustproof window cover provided in this application adopts the following technical solution:
[0006] A dustproof window cover includes a mounting base, on the surface of which the dustproof cover is mounted, and inside the dustproof cover is a dust removal component for removing dust from the surface of the roller shutter.
[0007] The dust removal assembly includes a strip-shaped limiting shell fixedly installed on the inner wall of the dust cover, a movable support frame slidably installed on the inner wall of the strip-shaped limiting shell, a dust removal roller rotatably installed on the surface of the movable support frame, and a limiting guide roller rotatably installed on the inner wall of the dust cover.
[0008] By adopting the above technical solution, the dust cover is fixed by the external mounting base and can be firmly installed on the window covering to form a closed structure, preventing dust from entering. The internal dust removal components, including the limiting shell, the movable support frame, and the dust removal roller, can automatically clean the surface of the roller blind during use. The sliding of the movable support frame and the rotation of the dust removal roller work together to enable the dust removal roller to effectively brush away the dust on the surface of the roller blind. The rotation of the limiting guide roller ensures the smooth operation of the dust removal roller and prevents it from deviating, thereby improving the dust removal effect and stability. Users do not need to manually clean the curtains, reducing the trouble of manual cleaning, and at the same time, effectively extending the service life of the window covering and keeping the surface of the curtains clean and tidy.
[0009] Optionally, the lower surface of the dust cover is provided with a roller shutter storage hole, which is located directly below the dust removal assembly, and the position of the dust removal roller corresponds to the limiting guide roller.
[0010] By adopting the above technical solution, the position of the dust removal roller corresponds to that of the limiting guide roller during the cleaning operation, ensuring the accurate movement of the dust removal roller on the roller shutter surface, avoiding deviation, and improving the cleaning effect.
[0011] Optionally, the inner wall of the strip-shaped limiting shell is provided with a plurality of support springs, one end of the support spring being fixedly connected to the surface of the movable support frame, and the other end of the support spring being fixedly connected to the inner wall of the strip-shaped limiting shell.
[0012] By adopting the above technical solution, the support spring installed inside the strip-shaped limiting shell can provide additional elastic support force, making the movable support frame more stable during sliding. One end of the support spring is fixedly connected to the movable support frame, and the other end is connected to the inner wall of the limiting shell, forming an elastic buffer mechanism to avoid excessive shaking or displacement of the movable support frame, thereby ensuring the smooth rotation of the dust removal roller and the stability of the dust removal effect.
[0013] Optionally, the movable support frame has a U-shaped structure, and both ends of the movable support frame are provided with limit slots. Both ends of the dust removal roller are fixedly provided with positioning shafts, and the positioning shafts are inserted and installed inside the limit slots.
[0014] By adopting the above technical solution, the limiting slots opened at both ends can cooperate with the positioning shafts at both ends of the dust removal roller to ensure that the dust removal roller is correctly positioned in the movable support frame, avoid its displacement or loosening, improve the rotation accuracy of the dust removal roller, make the dust removal process more efficient and stable, and at the same time enhance the service life and reliability of the entire dust removal component.
[0015] Optionally, the inner wall of the limiting slot is fixedly connected to two arc-shaped protrusions. The two arc-shaped protrusions are symmetrically distributed on the inner wall of the limiting slot. The arc-shaped protrusions are made of rubber and are used to prevent the positioning shaft from detaching.
[0016] By adopting the above technical solution, the two arc-shaped protrusions set on the inner wall of the limiting slot can effectively prevent the positioning shaft from falling off and being deviated during the rotation of the dust removal roller. The arc-shaped protrusions are made of rubber, which has good elasticity and friction, enhances the stable connection between the positioning shaft and the slot, effectively reduces friction damage, and extends service life.
[0017] Optionally, the surface of the mounting base is provided with a snap-fit mechanism, which is used to install and position the dust cover and the mounting base.
[0018] By adopting the above technical solution, the snap-fit mechanism on the surface of the mounting base can achieve quick installation and stable positioning between the dust cover and the mounting base. The snap-fit mechanism ensures that the dust cover is firmly fixed on the mounting base through simple snap-fit connection, preventing loosening or falling off, and providing a convenient installation method.
[0019] Optionally, the buckling mechanism includes two positioning boxes fixedly connected to the surface of the mounting base. A compression spring is fixedly installed inside the positioning box, and a positioning block is fixedly connected to the end of the compression spring. Positioning holes are provided on both the left and right sides of the dust cover. The position of the positioning holes corresponds to the positioning block, and the size of the positioning holes matches the positioning hole.
[0020] By adopting the above technical solution, the buckle mechanism uses the compression spring and positioning block inside the positioning box to ensure precise docking between the dust cover and the mounting base. The function of the compression spring is to provide elasticity so that the positioning block can automatically insert into the positioning hole of the dust cover, achieving firm fixation and accurate positioning. The matching of the positioning hole and the block makes the connection between the dust cover and the mounting base more stable and reliable. At the same time, it can be easily released during disassembly, which is convenient for maintenance and replacement.
[0021] Optionally, the mounting base has an L-shaped structure, and two T-shaped blocks are fixedly connected to the surface of the mounting base. Two limiting plates are fixedly connected inside the dust cover, and the surface of the limiting plates is provided with strip-shaped fixing holes that match the T-shaped blocks.
[0022] By adopting the above technical solution, the L-shaped mounting base and the dust cover are connected more securely through T-shaped clips and limiting plates. The T-shaped clips fixed on the mounting base can be accurately inserted into the strip-shaped fixing holes of the limiting plates inside the dust cover, ensuring that the dust cover is accurately and securely positioned during installation, effectively preventing the dust cover from loosening or shifting, and improving the stability and durability of the entire system.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By installing a dust removal component inside the roller blind casing, the dust removal roller on the surface of the movable support frame can be driven by the support spring to slide against the outside of the blind during the rolling process. The dust removal roller can then clean the surface of the roller blind, especially the side of the roller blind that is closest to the outside of the window. This prevents dust from being collected inside the dust cover along with the roller blind, thus improving the smoothness of the curtain's opening and closing process.
[0025] 2. By setting a snap-fit mechanism between the mounting base and the dust cover, the dust cover can be directly inserted into the surface of the mounting base when it is installed and fixed. The positioning blocks are inserted into the positioning holes on both sides of the dust cover, and the positioning blocks are tightened and limited by compression springs. No bolts or other tools are needed, which makes it easy to install and disassemble. At the same time, the T-shaped blocks and limiting plates can be used to reinforce and stabilize the dust cover and the mounting base, further improving the sturdiness of the curtain cover.

[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0035] This application discloses a dustproof window cover. (Refer to...) Figure 1 and Figure 2 It includes a mounting base 1, a dust cover 2 is mounted on the surface of the mounting base 1, and a dust removal component 3 is provided inside the dust cover 2. The dust removal component 3 is used to remove dust from the surface of the roller shutter.
[0036] Reference Figure 4 and Figure 6 A latching mechanism 4 is provided on the surface of the mounting base 1. The latching mechanism 4 is used to install and position the dust cover 2 and the mounting base 1. The latching mechanism 4 includes two positioning boxes 401 fixedly connected to the surface of the mounting base 1. A compression spring 402 is fixedly installed inside the positioning box 401. A positioning block 403 is fixedly connected to the end of the compression spring 402. Positioning holes 5 are provided on both the left and right sides of the dust cover 2. The position of the positioning hole 5 corresponds to the positioning block 403, and the size of the positioning hole 5 matches the positioning block 403. By providing a latching mechanism 4 between the mounting base 1 and the dust cover 2, when installing and fixing the dust cover 2, the dust cover 2 can be directly inserted into the surface of the mounting base 1. Under the action of the support spring 306, the positioning block 403 is driven to be inserted into the positioning holes 5 on both sides of the dust cover 2. The compression spring 402 is used to tighten and limit the positioning block 403. No bolts or other tools are needed, which achieves the purpose of convenient installation and disassembly.
[0037] Mounting base 1 has an L-shaped structure, and two T-shaped clips 6 are fixedly connected to its surface. Two limiting plates 7 are fixedly connected inside the dust cover 2. The surface of the limiting plates 7 has strip-shaped fixing holes 8 that match the T-shaped clips 6. By setting the limiting plates 7 and T-shaped clips 6, when installing the dust cover 2, the T-shaped clips 6 can be inserted into the strip-shaped fixing holes 8 on the surface of the limiting plates 7, thereby using the T-shaped clips 6 and limiting plates 7 to reinforce the dust cover 2 and mounting base 1, further improving the firmness of the curtain cover.
[0038] Reference Figure 5 The dust removal component 3 includes a strip-shaped limiting shell 301 fixedly installed on the inner wall of the dust cover 2. A movable support frame 302 is slidably installed on the inner wall of the strip-shaped limiting shell 301. Several support springs 306 are installed on the inner wall of the strip-shaped limiting shell 301. One end of the support spring 306 is fixedly connected to the surface of the movable support frame 302, and the other end of the support spring 306 is fixedly connected to the inner wall of the strip-shaped limiting shell 301. A dust removal roller 303 is rotatably installed on the surface of the movable support frame 302. A limiting guide roller 304 is rotatably installed on the inner wall of the dust cover 2. A dust removal cotton sleeve is fixedly sleeved on the surface of the dust removal roller 303. The dust removal cotton sleeve can be used to vacuum and clean the surface of the curtain, and the dust removal cotton sleeve on the surface of the dust removal roller 303 can be replaced. The limiting guide roller 304 can limit and guide the curtain, making the curtain smoother during opening and closing.
[0039] Reference Figure 7 The movable support frame 302 has a U-shaped structure, and both ends of the movable support frame 302 have limit slots 307. Both ends of the dust removal roller 303 are fixedly provided with positioning shafts 308. The positioning shafts 308 are inserted into the inside of the limit slots 307. Two arc-shaped protrusions 309 are fixedly connected to the inner wall of the limit slots 307. The two arc-shaped protrusions 309 are symmetrically distributed on the inner wall of the limit slots 307. The arc-shaped protrusions 309 are made of rubber and are used to limit the positioning shafts 308 to prevent them from falling out of the limit slots 307. By providing the limit slots 307 on the surface of the movable support frame 302, the positioning shafts 308 at both ends of the dust removal roller 303 can be inserted into the limit slots 307, and the positioning shafts 308 are limited by the arc-shaped protrusions 309 to prevent them from falling out of the limit slots 307. This also facilitates the disassembly, cleaning, maintenance and replacement of the dust removal roller 303.
[0040] Reference Figure 2 The lower surface of the dust cover 2 is provided with a roller blind storage hole 305, which is located directly below the dust removal component 3. The position of the dust removal roller 303 corresponds to the limiting guide roller 304. By setting the dust removal component 3 inside the roller blind cover, the curtain can pass over the surface of the dust removal roller 303 during the rolling process, and the dust removal roller 303 can limit and support the outside of the curtain. During the movement of the curtain, the dust removal roller 303 can contact and slide the outside of the curtain, and then use the dust removal roller 303 to clean the surface of the roller blind. The surface of the roller blind near the outside of the window can be cleaned and dusted, preventing dust from being collected into the inside of the dust cover 2 along with the roller blind, thus improving the smoothness of the curtain's opening and closing process.
[0041] The implementation principle of a dustproof window cover according to an embodiment of this application is as follows: When the curtain is rolled up, the dust removal roller 303 contacts the surface of the curtain, and can roll on the surface of the curtain as the curtain moves, thereby achieving the purpose of dust removal and cleaning of the curtain. This prevents dust adsorbed on the outside side of the curtain from being carried into the dustproof cover 2, thus preventing dust from being rolled into the curtain and facilitating subsequent curtain opening and closing operations.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
