Description

Technical Field

[0001] This utility model mainly relates to the field of furniture cleaning tools, specifically a folding window cleaner. Background Technology

[0002] Furniture cleaning supplies are specialized tools or equipment designed to keep furniture and home environments clean and hygienic. They cover a wide range of areas and have diverse functions.

[0003] Among the many furniture cleaning tools, window cleaners are a niche tool specifically designed for cleaning windows. A window cleaner is a tool or device specifically designed to clean window glass and frames. It removes dust, water stains, oil stains, and dirt from the glass surface through physical contact, adsorption, scraping, or spraying cleaning liquid to achieve a clean and transparent effect. However, most products have a straight rod structure, cannot be folded, are inconvenient to carry, and need to be placed vertically or occupy a large area when stored. Some products can only be folded at 90° on a single joint, and are still long and narrow after folding. Furthermore, the joints are prone to breakage due to frequent folding, and the straight rods are all thin and long, making them easy to break and lacking sufficient gripping points. Utility Model Content

[0004] This utility model addresses the problem that existing technical solutions are too simplistic by providing a folding window cleaner, which solves the technical problems mentioned in the background section regarding the inability to fold and the inconvenience of carrying.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A folding window cleaner includes a handle, a connecting seat, and a wiping frame. The handle and the wiping frame are rotatably connected via the connecting seat. A squeegee is slidably connected to one side of the wiping frame via a slider, and a cleaning brush is movably connected to one side of the squeegee.

[0007] The connecting seat includes a first base, a support rod, a second base, and a sleeve rod. One end of the second base is fixedly connected to the sleeve rod, and the other end is fixedly connected to the outer wall of the wiping rack. One end of the first base is rotatably connected to the support rod through a damping hinge.

[0008] The wiping rack includes a first wedge block, a second wedge block, and a limiting side plate. The limiting side plate is fixed to both ends of the edge of the wiping rack. One end of the first wedge block is movably connected to the inner side of the limiting side plate on the same side via a spring. The side of the first wedge block adjacent to the wiping rack is slidably connected to a corresponding groove on the surface of the wiping rack via a slider.

[0009] Furthermore, one end of the support rod is spherical and rotatably connected to a corresponding slot in the grip handle, and a slot plug that mates with the slot is fixed to the outer wall of the grip handle at the slot by a rubber band.

[0010] Furthermore, a bearing is provided on the inner side of the first base, and one end of the sleeve rod passes through the bearing and is fixedly connected to the inner ring of the bearing. The sleeve rod adopts an inner and outer nested telescopic structure, and its small diameter end is fixed to the axis of the second base. The outer wall of the second base is provided with an annular edge strip, and the surface of the first base is provided with a corresponding groove that engages with the annular edge strip.

[0011] Furthermore, fixed posts are symmetrically arranged at both ends of the top of the wiping rack surface. One end of each of the two compression springs is sleeved on the fixed posts and fixed, and the other end is fixedly connected to both ends of the top of the wiper frame. The second wedge block is fixed to the end of the wiper frame near the first wedge block, and the tangential angle between the second wedge block and the first wedge block is 45°. The end of the first wedge block away from the second wedge block forms an elastic reset structure through the compression spring.

[0012] Furthermore, limiting rods are provided on both sides of the cleaning brush holder, and compression springs are installed at corresponding positions on the surface of the wiping rack. One end of the spring is fixed to the wiping rack, and the other end is fixedly connected to the top of the limiting rod. The spring assembly at the top of the cleaning brush and the spring assembly at the top of the squeegee are staggered. At the same time, the surface of the limiting side plate is provided with slots for engaging the upper limiting rod of the cleaning brush holder.

[0013] Furthermore, the wiping rack, through the first base and support rod, forms a 180° rotating and folding mechanism with the grip handle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By using the ball joint of the support rod and the damping hinge of the first base, the wiping rack and the handle can be folded together at 180°, compressing the overall length from when unfolded to about 1 / 2, reducing the volume and making it easy to carry and store.

[0016] 2. The bearing connection between the sleeve and the first base supports 360° rotation of the wiping frame without dead angles, which facilitates the adjustment of the wiping frame angle and allows the squeegee or cleaning brush to be adjusted to the appropriate working angle. At the same time, a corresponding interlocking structure is provided to prevent accidental rotation. Both the cleaning brush and the squeegee are expanded and retracted by the elastic structure of the springs. The spring components of the two are staggered to ensure that they do not interfere with each other when operating simultaneously.

[0024] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0026] Please refer to the appendix carefully. Figure 1-4 A folding window cleaner includes a handle 1, a connecting seat 2, and a wiping frame 3. The handle 1 and the wiping frame 3 are rotatably connected through the connecting seat 2. A squeegee 4 is slidably connected to one side of the wiping frame 3 via a slider, and a cleaning brush 5 is movably connected to one side of the squeegee 4.

[0027] The connecting seat 2 includes a first base 201, a support rod 202, a second base 203 and a sleeve rod 204. One end of the second base 203 is fixedly connected to the sleeve rod 204, and the other end is fixedly connected to the outer wall of the wiping rack 3. One end of the first base 201 is rotatably connected to the support rod 202 through a damping hinge.

[0028] The wiping rack 3 includes a first wedge block 301, a second wedge block 302, and a limiting side plate 303. The limiting side plate 303 is fixed to both ends of the edge of the wiping rack 3. One end of the first wedge block 301 is movably connected to the inner side of the limiting side plate 303 on the same side by a spring. The side of the first wedge block 301 adjacent to the wiping rack 3 is slidably connected to the corresponding groove opened on the surface of the wiping rack 3 by a slider.

[0029] In this embodiment, as Figure 3 As shown, one end of the support rod 202 is spherical and is rotatably connected to the corresponding slot in the grip handle 1. The outer wall of the grip handle 1 at the slot is fixed with a slot plug that matches the slot by a rubber band.

[0030] With the above structure, when stored, the support rod 202 can be rotated 90° backward through the ball joint, and then combined with the folding joint of the first base 201, so that the wiping rack 3 and the handle 1 are finally in 180° contact, and the overall length is shortened to 1 / 2. The rubber strip fixes the slot plug and forms a limit, effectively preventing the support rod 202 from rotating accidentally.

[0031] In this embodiment, as Figure 3 As shown, a bearing is provided on the inner side of the first base 201, and one end of the sleeve rod 204 passes through the bearing and is fixedly connected to the inner ring of the bearing. The sleeve rod 204 adopts an inner and outer nested telescopic structure, and its small diameter end is fixed to the axis of the second base 203. The outer wall of the second base 203 is provided with an annular edge strip, and the surface of the first base 201 is provided with a corresponding groove that engages with the annular edge strip. The annular edge strip is made of nitrile rubber.

[0032] With the above structure, the sleeve 204 adopts an inner and outer nested telescopic structure. When it is necessary to adjust the angle of the wiping rack 3, the user holds the second base 203 and pulls it up to one side of the wiping rack 3. The small diameter end of the sleeve 204 extends outward from the inside of the large diameter end, so that the second base 203 disengages from the slot on the surface of the first base 201, preparing for subsequent rotation operation. When the user finishes using the sleeve or when it is necessary to fix the angle, the second base 203 is pushed into the first base 201, the sleeve 204 retracts, and the annular edge strip on the outer wall of the second base 203 is precisely inserted into the corresponding slot of the first base 201. The rubber edge strip generates a large friction force due to its elastic deformation, achieving a stable lock and preventing accidental rotation or loosening during the cleaning process.

[0033] In this embodiment, as Figure 4 As shown, fixed posts are symmetrically arranged at both ends of the top of the wiper rack 3. One end of each of the two compression springs is sleeved on the fixed posts and fixed, and the other end is fixedly connected to both ends of the top of the wiper plate 4. The second wedge block 302 is fixed to the end of the wiper plate 4 near the first wedge block 301. The angle between the tangent of the second wedge block 302 and the first wedge block 301 is 45°. The end of the first wedge block 301 away from the second wedge block 302 is formed by the compression spring to form an elastic reset structure.

[0034] With the above structure, when the wiper blade 4 is held and pulled down, the compression spring is stretched, causing the wiper blade 4 to slide down along the wiping frame 3. At the same time, the 45° wedge-shaped block slope pushes the first wedge block 301 to compress the spring and slide laterally until the second wedge block 302 completely passes over the first wedge block 301. After the second wedge block 302 passes, the first wedge block 301 instantly rebounds under the action of the return spring and locks on the top of the second wedge block 302, forming a mechanical self-locking mechanism. No manual buckle or button is required, and the extension and locking can be completed in a few seconds. One-handed operation is easy and convenient. After cleaning, the first wedge block 301 is pulled open by the pull rod set on the first wedge block 301, and the wiper blade 4 quickly returns to the initial position under the spring pull, realizing the retraction.

[0035] In this embodiment, as Figure 4 As shown, limiting rods are provided on both sides of the cleaning brush 5 frame, and compression springs are installed at corresponding positions on the surface of the wiping frame 3. One end of the spring is fixed to the wiping frame 3, and the other end is fixedly connected to the top of the limiting rod. The spring assembly at the top of the cleaning brush 5 and the spring assembly at the top of the squeegee 4 are staggered. At the same time, the surface of the limiting side plate 303 is provided with slots for engaging the upper limiting rod of the cleaning brush 5 frame.

[0036] With the above structure, by pulling down the cleaning brush 5, the elastic deformation of the spring causes the limiting rod to disengage from the initial slot. After rotating to the target position, it is released, and the limiting rod automatically snaps into the new slot under the spring tension. The cleaning brush 5 can be unfolded / folded without additional tools. The spring assembly at the top of the cleaning brush 5 is offset from the spring assembly at the top of the squeegee 4 to ensure that the two do not interfere with each other during unfolding or folding.

[0037] In this embodiment, as Figure 1 and Figure 2 As shown, the wiping rack 3 forms a 180° rotating and folding mechanism with the handle 1 via the first base 201 and the support rod 202.

[0038] With the above structure, in the unfolded state, the wiping rack 3 and the handle 1 extend in a straight line, making it easy for the user to grip and apply force, and also expanding the cleaning area. When storing, through two 90° folds, the wiping rack 3 is finally attached to the back of the handle 1, and the overall length can be reduced to 1 / 2 of the unfolded state. Compared with traditional fixed window cleaners, the "pole body + cleaning head" can be folded in one piece without disassembling parts, solving the pain point of "difficult to store" of traditional tools, and can be easily put into drawers, cleaning kits or car trunks.

[0039] The specific operating procedure of this utility is as follows: Before use, ensure that the slot plug on the side of the handle 1 is engaged in the corresponding slot of the support rod 202 to prevent the support rod 202 from rotating accidentally, thus preparing for stable operation in the future.

[0040] When the wiper blade 4 needs to be used to clean the glass, pull the wiper blade 4 down. The slider at the top of its frame slides down into the corresponding groove of the wiping frame 3. At the same time, the springs at both ends gradually stretch. During the sliding process of the wiper blade 4, the second wedge block 302 at one end gradually comes into contact with the first wedge block 301. The relative tangential angle between the two is 45°. When the wiper blade 4 slides toward the first wedge block 301, the tangential surface of the second wedge block 302 pushes the first wedge block 301 to compress the spring and slides along the horizontal groove on the surface of the wiping frame 3. At this time, the spring on one side of the first wedge block 301 is compressed.

[0041] When the second wedge 302 completely passes through the first wedge 301, it loses external force. The first wedge 301 is reset under the action of the spring and blocks the second wedge 302 from below, ensuring the stability of the wiper blade 4 after it is unfolded, which facilitates subsequent wiping of the glass window. The wiper blade 4 is made of PC material and gradually narrows at the bottom, which is conducive to adhering to the glass surface for wiping operation.

[0042] When cleaning the window track and other parts with the cleaning brush 5, pull the cleaning brush 5 down. Since the two ends of the cleaning brush 5 are movably connected to the wiping frame 3 by springs, when pulling down, the limiting rod on the top frame is engaged in the corresponding groove of the limiting side plate 303 to fix it. The bottom of the cleaning brush 5 is made of nylon fiber bundles, which are not easily deformed, fall off and have good elasticity, effectively removing stubborn stains such as dust in the window frame track.

[0043] If it is necessary to adjust the angle of the wiping frame 3 so that the squeegee 4 or cleaning brush 5 is at a suitable working angle, the user can hold the second base 203 and pull it up to one side of the wiping frame 3. The sleeve 204 is a telescopic structure. At this time, the sleeve 204 is unfolded and the length of the rod increases. With the help of the second base 203 which is fixedly connected to the sleeve 204, the wiping frame 3 can rotate on the surface of the first base 201 which is rotatably connected to the sleeve 204. After the user adjusts it to a suitable angle according to actual needs, he holds the second base 203 and pushes it to one side of the first base 201 so that the annular edge strip on the surface of the second base 203 is inserted into the corresponding slot of the first base 201. At the same time, the insertion strip of the second base 203 is made of rubber, which increases the friction and reduces the probability of the second base 203 rotating unnecessarily, ensuring the stability of the adjusted angle.

[0044] After use, the damping hinge between the support rod 202 and the first base 201 is used to make the first base 201 drive the wiping rack 3 to flip and fold 90°. Then, with the help of the rotation of the support rod 202 and the handle 1, it flips and folds 90° again, and finally achieves 180° rotation and folding of the wiping rack 3, which is convenient for storage and reduces space occupation. When the wiper blade 4 needs to slide and retract in the opposite direction, the first wedge block 301 is pulled away from one end of the second wedge block 302, and the wiper blade 4 at the end of the wiping rack 3 is reset and retracted by the spring and the slider through the two tension springs.

[0045] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
