Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and specifically to door and window cleaning components. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Aluminum alloy doors and windows refer to doors and windows made with aluminum alloy extruded profiles as frames, mullions, and sashes. They are also known as aluminum doors and windows, and include those using aluminum alloy as the load-bearing member (the member that bears and transmits its own weight and load) and those made of wood or plastic composites, referred to as aluminum-wood composite doors and windows or aluminum-plastic composite doors and windows. Most existing aluminum alloy doors and windows lack cleaning capabilities; after long-term use, the glass in the inner frame accumulates dust. Currently, this is done manually by wiping with a damp cloth, which is time-consuming, labor-intensive, and inefficient, failing to meet the required standards.

[0004] In related technologies, Chinese utility model patent CN221308066U discloses a window and door surface cleaning component, including a left column, a right column, a motor, and a screw. A screw block is threadedly connected to the outer side of the screw. A first forward linkage rod is fixedly installed on the front of the screw block, and a first back linkage rod is fixedly installed on the back of the screw block. A forward cleaning scraper is fixedly installed at one end of the first forward linkage rod, and a back cleaning scraper is fixedly installed at one end of the first back linkage rod. A sliding rod is fixedly installed inside the right column, and a slider is slidably connected to the outer side of the sliding rod. A second forward linkage rod is fixedly installed on the front of the slider, and a second back linkage rod is fixedly installed on the back of the slider. By scraping and cleaning the front and back of the glass window with the forward and back cleaning scrapers, the inner and outer surfaces of the glass can be cleaned simultaneously, resulting in a comprehensive and effective cleaning of the window and door. This saves time and effort, improves cleaning efficiency, and meets daily usage needs.

[0005] However, the aforementioned patented technology has certain drawbacks, namely:

[0006] After the squeegee scrapes the dirt on the glass window from top to bottom, if the next cleaning is needed, the squeegee needs to be driven back to the top of the glass window from bottom to top. However, since the squeegee is always attached to the surface of the glass window, during this process the squeegee will bring some dirt back to the cleaned surface of the glass window, causing re-contamination and resulting in poor cleaning effect on the glass window.

[0007] In response, this application proposes a door and window cleaning component to solve the aforementioned problems. Utility Model Content

[0008] The main purpose of this utility model is to provide a door and window cleaning component.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows: a door and window cleaning assembly, which is used to clean the main body of doors and windows installed on a bracket, includes two bases, which are vertically movable and respectively arranged on both sides of the bracket;

[0010] The two bases are equipped with the same scraper for cleaning the main surface of the doors and windows; the bracket is equipped with an actuating mechanism.

[0011] When the base moves vertically downward, the actuating mechanism can drive the scraper to adhere to the surface of the door / window body; when the base moves vertically upward, the actuating mechanism can cause the scraper to detach from the surface of the door / window body.

[0012] Furthermore, the actuation mechanism includes two first sliders, which are respectively disposed inside two bases and can move horizontally relative to each other in the corresponding bases, parallel to the surface of the door and window body.

[0013] Two second sliders are provided on opposite sides of the two bases, and each slider can move horizontally relative to the corresponding base in a direction perpendicular to the surface of the door or window body.

[0014] The scraper is fixed at both ends to the opposite sidewalls of the two second sliders;

[0015] The end of the first slider that is close to the scraper can press against the end of the corresponding second slider that is away from the scraper.

[0016] The base is provided with a driving component, which can drive the corresponding first slider to approach the corresponding second slider horizontally and press against it when the base moves vertically downward, thus pushing the corresponding second slider closer to the surface of the door and window body.

[0017] Furthermore, the base has a first groove that slides and engages with the first slider inside, and a second groove that slides and engages with the second slider on the side of the base near the scraper. The end of the first groove near the scraper is perpendicularly connected to the end of the second groove away from the door and window body.

[0018] Furthermore, a telescopic rod is provided between the side of the second slider facing the door / window body and the corresponding groove wall of the second slide. A spring is sleeved on the outside of the telescopic rod. When the first slider and the second slider are pressed together, the telescopic rod and the spring are in a compressed state.

[0019] Furthermore, the first slider has a first inclined surface that engages with the second slider upon contact.

[0020] Furthermore, the drive assembly includes a limiting rod vertically fixed on the bracket, a through groove for the limiting rod to move through on the base, and multiple movable blocks axially and equally spaced on the outer wall of the limiting rod, which are perpendicular to the axis of the limiting rod. The top of the movable blocks has a second inclined surface that faces the scraper direction and slopes downward.

[0021] The first slider has a connecting rod at the end away from the scraper. One end of the connecting rod extends into the through groove and is fixed with a transmission plate.

[0022] The bottom of the transmission plate contacts and engages with the second inclined surface. When the base moves vertically downward, the transmission plate pushes the first slider to move horizontally closer to the scraper via the connecting rod.

[0023] The top of the transmission plate contacts and engages with the bottom of the movable block. When the base moves vertically upward, it drives the movable block to deflect upward parallel to the limit rod, allowing the transmission plate to move upward synchronously with the base.

[0024] Furthermore, the vertical length of the transmission plate is greater than the vertical distance between the bottom walls of two adjacent moving blocks.

[0025] Furthermore, an ear block is fixed on the outer wall of the limiting rod, and a rolling hole is opened on the ear block. A scroll is inserted into the rolling hole, and a coil spring is sleeved on the outside of the scroll. The two ends of the coil spring are respectively connected to the wall of the rolling hole and the outer wall of the scroll. A connecting block is fixed on one end of the movable block near the limiting rod. The connecting block is sleeved and fixed on the outside of the scroll. When the movable block deflects upward to be parallel to the limiting rod, the coil spring is in a compressed state.

[0026] Furthermore, a support groove is provided on the bottom of the movable block near the limiting rod, and a support block that cooperates with the support groove is provided on the outer wall of the limiting rod.

[0027] Furthermore, two transmission rods are arranged vertically on the bracket, and two bases are threaded onto the outside of the two transmission rods respectively; a drive motor is installed on the top of the bracket, and the bottom of the output shaft of the drive motor is connected to the top of the corresponding transmission rod.

[0028] The beneficial effects of this utility model are reflected in:

[0029] The door and window cleaning component of this utility model adds an actuating mechanism to the original door and window bracket, so that the downward scraper is always attached to the surface of the door and window body, while it is detached from the surface of the door and window body when it moves upward, so as to avoid the stains being brought back and causing re-contamination, and to ensure the cleaning effect.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0041] Please combine Figures 1 to 7 .

[0042] A door and window cleaning assembly for cleaning door and window bodies 100 mounted on a bracket 1 includes two bases 2, which are vertically movable and respectively disposed on both sides of the bracket 1.

[0043] Two bases 2 are equipped with the same scraper 5 for scraping and cleaning the surface of the door and window body 100, which moves synchronously between them. The bracket 1 is equipped with an actuating mechanism.

[0044] When the base 2 moves vertically downward, the actuating mechanism can drive the scraper 5 to adhere to the surface of the door / window body 100. When the base 2 moves vertically upward, the actuating mechanism can cause the scraper 5 to detach from the surface of the door / window body 100.

[0045] In practice, when the base 2 moves the scraper 5 downward relative to the surface of the door and window body 100, the actuating mechanism can drive the scraper 5 to adhere to the surface of the door and window body 100 and scrape the door and window body 100 from top to bottom for cleaning. When the base 2 moves vertically upward, the actuating mechanism can make the scraper 5 detach from the surface of the door and window body 100, avoiding bringing back the dirt scraped during the downward movement to contaminate the cleaned surface of the door and window body 100. This allows for unidirectional scraping cleaning of the door and window body 100 from top to bottom.

[0046] In one embodiment, the actuation mechanism includes two first sliders 7, which are respectively disposed inside two bases 2 and can move horizontally relative to each other in the corresponding bases 2, parallel to the surface of the door and window body 100.

[0047] Two second sliders 9 are provided on opposite sides of the two bases 2, and can move horizontally relative to each other in the corresponding base 2, perpendicular to the surface of the door and window body 100.

[0048] The scraper 5 is fixed at both ends to the opposite side walls of the two second sliders 9.

[0049] The end of the first slider 7 near the scraper 5 can press and engage with the end of the corresponding second slider 9 away from the scraper 5.

[0050] The base 2 is provided with a driving component. When the base 2 moves vertically downward, the driving component can drive the corresponding first slider 7 to move horizontally close to the corresponding second slider 9 and press against it, pushing the corresponding second slider 9 close to the surface of the door and window body 100.

[0051] Thus, when the base 2 moves the scraper 5 downward, the first slider 7 can be moved horizontally towards the scraper 5 by the drive component to press the corresponding second slider 9, which forces the second slider 9 to move the scraper 5 towards the surface of the door and window body 100, so that the scraper 5 is attached to the surface of the door and window body 100, so that the surface of the door and window body 100 can be scraped and cleaned from top to bottom when it moves downward.

[0052] When the base 2 moves the scraper 5 upward, the drive component will not drive the corresponding first slider 7 to move horizontally close to the corresponding second slider 9. Thus, there is a gap between the scraper 5 and the surface of the door and window body 100, preventing the scraper 5 from moving upward and bringing the dirt scraped at its bottom back to the cleaned surface of the door and window body 100.

[0053] In one embodiment, the base 2 has a first groove 6 that slides with the first slider 7, and the base 2 has a second groove 8 that slides with the second slider 9 on the side near the scraper 5. The end of the first groove 6 near the scraper 5 is vertically connected to the end of the second groove 8 away from the door and window body 100.

[0054] Thus, the first slider 7 and the second slider 9 can move relative to each other in the base 2, and the first slider 7 can extend into the second groove 8 and press against the second slider 9.

[0055] In one embodiment, a telescopic rod 10 is provided between the side of the second slider 9 facing the door / window body 100 and the corresponding groove wall of the second slide groove 8, and a spring (not shown) is sleeved on the outside of the telescopic rod 10.

[0056] Thus, when the first slider 7 and the second slider 9 are in contact, the telescopic rod 10 and the spring are in a compressed state; when the first slider 7 is not in contact with the second slider 9, the telescopic rod 10 and the spring are in a non-deformed state.

[0057] In one embodiment, the first slider 7 has a first inclined surface 11 that engages with the second slider 9. When the first slider 7 is inserted into the second slide groove 8, it can press the second slider 9 through its first inclined surface 11, forcing the second slider 9 to move horizontally in the second slide groove 8 toward the direction of the door and window body 100.

[0058] In one embodiment, the driving assembly includes a limiting rod 4 vertically fixed on the bracket 1. A through groove 20 is provided on the base 2 for the limiting rod 4 to move through. Multiple movable blocks 16 are elastically arranged on the outer wall of the limiting rod 4 at equal intervals and perpendicular to the axial direction of the limiting rod 4. The top of the movable block 16 has a second inclined surface 17 that faces the scraper 5 and is inclined downward.

[0059] A connecting rod 12 is provided at the end of the first slider 7 away from the scraper 5. One end of the connecting rod 12 extends into the through groove 20 and is fixed with a transmission plate 13. The transmission plate 13 is parallel to the limiting rod 4.

[0060] The bottom of the transmission plate 13 contacts and engages with the second inclined surface 17. When the base 2 moves vertically downward, the transmission plate 13 pushes the first slider 7 to move horizontally closer to the scraper 5 via the connecting rod 12.

[0061] The top of the transmission plate 13 contacts and engages with the bottom of the movable block 16. When the base 2 moves vertically upward, the movable block 16 is driven to deflect upward parallel to the limit rod 4, so as to provide clearance space for the transmission plate 13 to move upward, thereby allowing the transmission plate 13 to move upward synchronously with the base 2.

[0062] Thus, when the base 2 moves the scraper 5 downward, the transmission plate 13 moves downward with the base 2. The bottom of the transmission plate 13 touches the second inclined surface 17 on the top of the movable block 16. Under the guidance of the second inclined surface 17, the transmission plate 13 will drive the first slider 7 to move towards the scraper 5 through the connecting rod 12, and complete the contact and cooperation with the second slider 9, so that the scraper 5 moves towards the door and window body 100. Since there are multiple movable blocks 16 on the outer wall of the limiting rod 4, the movable blocks 16 can contact and cooperate with the second inclined surface 17 of each movable block 16 in sequence in its moving direction, so that the scraper 5 can adhere to the surface of the door and window body 100 when it moves downward, and complete the top-to-bottom scraping cleaning of the surface of the door and window body 100.

[0063] Preferably, the vertical length of the transmission plate 13 is greater than the vertical distance between the bottom walls of two adjacent movable blocks 16.

[0064] Thus, when the transmission plate 13 moves from top to bottom between two adjacent movable blocks 16, except for the uppermost movable block 16, the side of the transmission plate 13 can always maintain sliding contact with the side wall of the other movable blocks 16 near the scraper 5, ensuring that the scraper 5 can always adhere to the surface of the door and window body 100 when it moves down. In addition, it prevents the transmission plate 13 from accidentally entering the gap between two adjacent movable blocks 16 and getting stuck when it moves down, and avoids interfering with the downward movement of the base 2 and the scraper 5.

[0065] In one embodiment, an ear block 14 is fixed to the outer wall of the limiting rod 4. The ear block 14 has a rolling hole (not shown), into which a scroll 15 is inserted. A coil spring (not shown) is sleeved on the outside of the scroll 15. The two ends of the coil spring are connected to the wall of the rolling hole and the outer wall of the scroll 15, respectively. A connecting block is fixed to one end of the movable block 16 near the limiting rod 4. The connecting block is sleeved and fixed to the outside of the scroll 15. When the movable block 16 deflects upwards to be parallel to the limiting rod 4, the coil spring is in a compressed state. Thus, the elastic force of the coil spring allows the transmission plate 13 to help the movable block 16 return to a horizontal state after disengaging from the movable block 16.

[0066] In one embodiment, a support groove 19 is provided on the bottom side of the movable block 16 near the limiting rod 4, and a support block 18 that cooperates with the support groove 19 is provided on the outer wall of the limiting rod 4. This not only limits the maximum rotation angle of the movable block 16 to ninety degrees, but also provides effective support for the movable block 16 when it is horizontal.

[0067] In one embodiment, two transmission rods 3 are vertically arranged on the bracket 1, and two bases 2 are threaded onto the outside of the two transmission rods 3 respectively. A drive motor 21 is installed on the top of the bracket 1, and the bottom of the output shaft of the drive motor 21 is connected to the top of the corresponding transmission rod 3.

[0068] The output shaft of the drive motor 21 drives the two transmission rods 3 to rotate so as to engage with the threaded holes on the corresponding base 2, thereby adjusting the position of the base 2 and the scraper 5 in the vertical direction.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0070] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0071] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
