Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to a double-sided cleaning device. Background Technology

[0002] Cleaning windows is an important part of daily life in homes and offices, especially cleaning exterior windows at high altitudes, which can be quite dangerous. Current technology generally uses magnetic window cleaners, where two cleaners are attached to the inside and outside of the glass using strong magnets and then moved along the glass surface to clean. However, this method relies on magnetic attraction; when the magnetic force is weak, the cleaners easily fall off, posing a significant danger; when the magnetic force is strong, the two cleaners are difficult to separate, making it inconvenient to use.

[0003] Therefore, Chinese patent application number 201821560075.5 proposed a double-sided glass cleaner, which uses a U-shaped rod with cleaning heads at both ends to clean both sides of the glass at the same time. However, this glass cleaner requires the user to lift the entire glass cleaner with the handle to clean it, which is quite strenuous. Especially when the cleaning head is wet or has a water storage device, the weight of the entire glass cleaner is heavy. Users are easily fatigued by holding the heavy glass cleaner for a long time, and it is inconvenient to clean different parts of the glass. Utility Model Content

[0004] In view of this, the present invention provides a double-sided cleaning device to solve the problem that in the prior art, double-sided glass cleaners that clean both sides in conjunction with each other require the user to hold the entire glass cleaner continuously, which can easily lead to fatigue and high workload.

[0005] This utility model provides a double-sided cleaning device, comprising:

[0006] The cleaning head has two sets, which are located on the inner and outer sides of the part to be cleaned.

[0007] The handle connects to the cleaning head located inside the item to be cleaned;

[0008] The inner and outer support rods are each connected to a set of cleaning heads at one end, and the other ends are connected to each other.

[0009] The adjustable fixing device is suitable for being adjusted and fixed at different positions on the part to be cleaned; the adjustable fixing device is rotatably connected to both the inner support rod and the outer support rod, so that when the handle drives the cleaning head located on the inner side of the part to be cleaned to move along the inner side of the part to be cleaned, the inner support rod rotates around the adjustable fixing device, and the outer support rod rotates accordingly, thereby driving the cleaning head located on the outer side of the part to be cleaned to move synchronously.

[0010] Beneficial effects: The double-sided cleaning device, with its adjustable fixing mechanism, can be fixed in different positions on the item to be cleaned without falling off. This allows for convenient cleaning of different areas of the item, and the item can support the weight of the device. Users only need to hold the handle and operate it to simultaneously rotate the inner and outer cleaning heads to clean both sides of the item synchronously. It is lightweight and convenient to use, eliminating the need for users to constantly hold the device up. The device can be stably maintained at the preset height, reducing user workload and improving the user experience. It effectively solves the problem of existing double-sided glass cleaners that require users to constantly hold the entire cleaner, leading to fatigue and high workload.

[0011] Furthermore, in this embodiment, the adjustable fixing device can not only be used to fix the entire double-sided cleaning device, but also its two ends are rotatably connected to the inner support rod and the outer support rod respectively. The adjustable fixing device is connected in the middle position of the inner support rod and the outer support rod. In this way, when cleaning the item to be cleaned, you only need to hold the handle and move the handle to clean the glass on the arc surface with the connection point between the adjustable fixing device and the inner and outer support rods as the center and the distance from the connection point to the cleaning head as the radius. It not only has a large cleaning range, but also has the advantages of flexible movement and not easy to fall off.

[0012] In one optional embodiment, the adjustable fixing device is provided with rotating connecting components on both sides. The inner support rod and the outer support rod are rotatably connected to the adjustable fixing device through a rotating connecting component, and the direction of the rotation axis is a first direction perpendicular to the inner or outer side of the part to be cleaned.

[0013] Beneficial effects: By setting rotating connecting components on both sides of the adjustable fixing device, the inner and outer support rods can be rotatably connected to the adjustable fixing device, thereby driving the cleaning head to rotate. The rotation axis of the rotating connecting components and the adjustable fixing device is perpendicular to the inner or outer side of the part to be cleaned, thus achieving the technical effect of driving the cleaning head to move along the surface of the part to be cleaned for wiping and cleaning.

[0014] In one alternative implementation, the rotary connection assembly includes:

[0015] Connecting seat, the connecting seat has a cavity inside, and one side is connected to the inner or outer support rod;

[0016] The rotating shaft has one end rotatably limited within the connecting seat, and the other end is limited by an adjustable fixing device to restrict the rotation of the rotating shaft in the first direction.

[0017] Beneficial effects: The rotary connection assembly adopts a design of a connecting seat and a rotating shaft. The connecting seat is connected to the inner and outer support rods and can rotate under the drive of the inner and outer support rods. The rotating shaft is designed with one end limited by an adjustable fixing device and the other end rotatably limited by the connecting seat. This design ensures that the connecting seat does not drive the rotating shaft to rotate when it rotates, and can rotate freely relative to the rotating shaft. This allows the inner and outer support rods to rotate freely relative to the adjustable fixing device.

[0018] In one optional embodiment, the rotating shaft includes a shaft body and a limiting plate fixedly disposed at one end of the shaft body;

[0019] The limiting plate is confined within the connecting seat, and the other end of the shaft extends out of the connecting seat and is connected to the adjustable fixing device;

[0020] The connecting seat includes a detachably connected seat body and a cover body, which interlock and enclose to form a cavity that can accommodate the limiting disc.

[0021] Beneficial effects: The rotating shaft adopts a design with a shaft body and a limiting plate fixed at one end of the shaft body. The cross-sectional area of ​​the limiting plate is larger than that of the shaft body. The limiting plate is limited in the cavity of the connecting seat and can rotate freely in the cavity. While realizing the rotational connection between the rotating shaft and the connecting seat, it can also effectively prevent the connecting seat from separating from the rotating shaft. The connecting seat adopts a design with a detachable seat body and cover body, which facilitates the assembly and connection between the rotating shaft and the connecting seat.

[0022] In one alternative implementation, the base and the cover are connected by screws.

[0023] Beneficial effects: The base and cover are connected by screws, which makes the connection reliable, stable, and easy to disassemble and assemble.

[0024] In one alternative embodiment, the inner support rod and the outer support rod are hinged to each other at the ends away from the cleaning head. The adjustable fixing device includes a linkage mechanism that is driven between the inner support rod and the outer support rod so that the two rods can simultaneously move closer to or further away from the part to be cleaned.

[0025] Beneficial effects: The inner and outer support rods, at their ends furthest from the cleaning head, are connected by a hinged joint. A linkage mechanism between the inner and outer support rods allows the inner support rod to rotate along the inner glass surface, driving the outer support rod to rotate as well. When the inner support rod moves away from the inner glass surface, the hinge point forms a fulcrum, which, through the linkage mechanism, pushes the outer support rod away from the outer glass surface as well. This allows both cleaning heads to simultaneously move away from or towards the inner and outer surfaces of the glass, achieving synchronized cleaning. Furthermore, the hinged connection ensures reliable connection and stable linkage, allowing the distance between the inner and outer support rods to be adjustable to accommodate glass of varying thicknesses. It also effectively avoids the structural damage that can result from rigid connections.

[0026] In one optional embodiment, the adjustable fixing device includes a support body, and the linkage mechanism includes:

[0027] The parallel four-bar linkage includes two first links and two second links arranged parallel to each other. The middle part of the first link is hinged to the support body, and both ends are hinged to the two second links respectively.

[0028] Two transition links, one end of which is hinged to the opposite corner of the parallel four-bar linkage, and the other end is movably connected to the inner and outer struts respectively.

[0029] Beneficial effects: The linkage mechanism, by adopting a parallel four-bar linkage and two transition links, has a simple structure, high stability, low cost, and high reliability of force transmission. The two transition links are connected at opposite corners of the parallel four-bar linkage, making it easier to pull the parallel four-bar linkage to move, further improving the reliability and synchronization of motion transmission between the inner and outer support rods.

[0030] In one optional embodiment, two hinge shafts are fixedly provided on the support body, and the middle of the two first connecting rods is provided with shaft holes corresponding to the two hinge shafts respectively.

[0031] Beneficial effects: The first connecting rod is connected to the hinge shaft on the support body by means of opening a shaft hole, so as to realize the rotational connection between the first connecting rod and the support body. The connection structure is simple and easy to process and form.

[0032] In one alternative embodiment, the adjustable fixing device further includes:

[0033] The first and second limiting components are fixedly installed on the support body and are respectively located on both sides of one of the first connecting rods to limit the stroke of the first connecting rod.

[0034] Beneficial effects: By setting the first limiting member and the second limiting member on both sides of the first link, the first limiting member and the second limiting member can limit the stroke of the first link, preventing the first link from rotating too much and causing interference or conflict between the linkage mechanism and other components or other components.

[0035] In one optional embodiment, the first limiting member and the second limiting member are limiting pins fixedly mounted on the support body.

[0036] Beneficial effects: The first and second limiting components adopt the structure of limiting pins, which is simple in structure. The outer circumference of the limiting pin is circular, which can effectively limit the stroke of the first link while forming a point-line contact with the first link. The contact area is small and the friction is small.

[0037] In one optional embodiment, when the adjustable fixing device is provided with rotating connecting components on both sides, and the rotating connecting components include connecting seats and rotating shafts, one end of the rotating shaft is rotatably limited in the connecting seat, and the other end is hinged to the end of the transition link away from the parallel four-bar linkage.

[0038] Beneficial effects: One end of the rotating shaft is rotatably limited within the connecting seat, while the other end is connected to the adjustable fixing device by hinged connection between the rotating shaft and the transition link, thus achieving a movable connection between the rotating shaft and the linkage mechanism, avoiding structural damage caused by hard connection, and improving the force transmission effect.

[0039] In one optional embodiment, the support body is a hollow shell structure with an internal cavity, the linkage mechanism is disposed inside the cavity, and through holes for the rotating shaft to pass through are respectively provided on the opposite side walls of the support body.

[0040] Beneficial effects: The support body adopts a hollow shell structure design and sets the linkage mechanism inside the support body, which hides the linkage mechanism and improves aesthetics. At the same time, the support body can also protect the linkage mechanism and prevent it from interfering with external parts or accumulating dust during operation.

[0041] In one alternative embodiment, the support body includes a first housing and a second housing that are interlocked with each other;

[0042] The first housing and the second housing each have two opening slots on their sides. After the first housing and the second housing are fastened together, the two opening slots on the first housing and the second housing are joined together to form two through holes for the rotating shaft to pass through.

[0043] Beneficial effects: The support body adopts a design of interlocking first and second shells, which facilitates the disassembly and assembly of the internal linkage mechanism. The through hole formed by splicing the opening slots on the first and second shells is more convenient for the installation of the rotating shaft than a one-piece circular through hole. During assembly, the rotating shaft is first placed in the opening slot on the first shell, and then the second shell is snapped onto the first shell, resulting in higher assembly efficiency.

[0044] In one alternative implementation, the inner diameter of the through hole is larger than the outer diameter of the shaft body.

[0045] Beneficial effects: By adopting a design where the inner diameter of the through hole is larger than the outer diameter of the shaft body, it is easier to install the shaft. At the same time, it can also ensure that the shaft can extend and retract in the axial direction of the through hole to drive the linkage mechanism, thereby realizing the synchronous movement between the inner and outer support rods.

[0046] In one alternative embodiment, the first housing and the second housing are fastened together and secured with screws.

[0047] Beneficial effects: The first and second housings are connected by screws, which makes the connection reliable, stable, and easy to disassemble and assemble.

[0048] In one alternative embodiment, the two sides of the adjustable fixing device are respectively connected to the inner support rod and the outer support rod via a first universal joint structure.

[0049] Beneficial effects: Through the first universal joint structure, when the linkage mechanism is activated, the inner and outer support rods can rotate relative to the main body. When the cleaning head is moved by rotating the handle, the rotation of the inner and outer support rods is convenient.

[0050] In one optional implementation, the first universal joint structure includes:

[0051] A sliding sleeve is slidably fitted onto the inner and outer support rods;

[0052] A first connecting block, the first connecting block being rotatably connected to the sliding sleeve in a first rotation direction;

[0053] The adjustable fixing device is provided with rotary connecting components at both ends, and the rotary connecting components are adapted to be rotatably connected to the first connecting block in the second rotation direction;

[0054] The first rotation direction is perpendicular to the second rotation direction.

[0055] Beneficial effects: The first universal connection structure employs a sliding sleeve design, with the sleeve slidingly fitted onto the inner and outer support rods. This sliding connection method is relatively simple. When adjusting the cleaning radius, the position of the sliding sleeve on the inner and outer support rods can be adjusted to change the cleaning radius of the cleaning head, allowing for cleaning of items within different radius ranges of the adjustable fixing device. Furthermore, the connection between the first connecting block and the sliding sleeve, as well as between the first connecting block and the rotating connecting assembly, allows the inner and outer support rods to rotate 360°, resulting in a larger cleaning range and greater practicality.

[0056] In one alternative embodiment, when the rotary connection assembly includes a connecting seat and a rotating shaft, the side of the connecting seat away from the rotating shaft is provided with a first rotary connection portion that is rotatably connected to the first connecting block.

[0057] Beneficial effects: The rotational connection between the rotating connection assembly and the first connecting block is achieved through the first rotating connection part, thereby realizing the connection between the inner support rod and the outer support rod and the adjustable fixing device.

[0058] In one alternative implementation, the first universal joint structure is connected to the inner and outer support rods via a sliding connection.

[0059] Beneficial effects: The first universal joint structure is connected to the inner and outer support rods via a sliding connection. By adjusting the position of the first universal joint structure on the inner and outer support rods, the distance between the cleaning head and the adjustable fixing device can be adjusted, thereby allowing for adjustment of the cleaning radius of the cleaning head to clean items within different radius ranges of the adjustable fixing device.

[0060] In one alternative implementation, the lengths of the inner and outer struts are adjustable.

[0061] Beneficial effects: The adjustable length design of the inner and outer support rods allows for adjustment of the cleaning head's position relative to the adjustable fixing device along the length of the inner and outer support rods, thereby adjusting the cleaning radius of the cleaning head.

[0062] In one alternative implementation, the inner and outer struts are telescopic rods or threaded multi-segment rods.

[0063] Beneficial effects: The internal and external support rods adopt a telescopic rod or a multi-segment rod structure with threaded connection, which makes it easy to adjust the position of the cleaning head relative to the adjustable fixing device in the length direction of the internal and external support rods.

[0064] In one alternative embodiment, the adjustable fixing device is adsorbed or clamped onto the part to be cleaned.

[0065] Beneficial effects: The adjustable fixing device can be adsorbed or clamped onto the part to be cleaned, making it easy to install and remove the adjustable fixing device, and also easy to adjust the fixing position of the adjustable fixing device on the part to be cleaned.

[0066] In one optional embodiment, the adjustable fixing device is clamped and fixed to the part to be cleaned by a clamping mechanism, the clamping mechanism comprising:

[0067] Clamping components, having two that are positioned opposite each other;

[0068] A locking element is provided on the clamping element. The locking element is used to adjust the clamping degree of the clamping mechanism when the two clamping elements are clamped on the workpiece to be cleaned, so as to accommodate workpieces of different thicknesses.

[0069] Beneficial effects: The clamping mechanism adopts a design with clamping and locking components. The two clamping components can clamp onto the part to be cleaned, and the locking component can adjust the clamping degree of the clamping mechanism, thus making it easy to adapt to parts of different thicknesses.

[0070] In one alternative embodiment, the clamping member is a clamping plate, and the locking member includes a locking bolt threaded onto the clamping plate;

[0071] One end of the locking bolt is adapted to pass through the clamping plate and abut against the part to be cleaned, while the other end is fixedly equipped with a knob.

[0072] Beneficial effects: The locking mechanism uses a locking bolt structure, achieving fixation through the contact force between the end of the locking bolt and the part to be cleaned. The structure is simple, and the connection offers high stability and reliability. It also facilitates adjustment of the clamping tightness. For example, when the clamping area of ​​the part to be cleaned is thicker, the locking bolt is screwed outwards so that the distance between the end of the locking bolt and the symmetrical clamping plates matches the thickness of the clamping area, thus achieving fixation. When the clamping area of ​​the part to be cleaned is thinner, the locking bolt is screwed inwards so that the end of the locking bolt firmly abuts against the part to be cleaned, achieving fixation. Furthermore, the addition of a knob makes the screwing operation even more convenient.

[0073] In one alternative embodiment, the locking element is disposed on the clamping element located inside the part to be cleaned.

[0074] Beneficial effect: By placing the locking element on the clamping element located inside the part to be cleaned, it is more convenient for users to perform the adjustment operation while standing indoors, compared to placing it on the outside of the part to be cleaned.

[0075] In one alternative implementation, the inner strut is connected to the cleaning head via a second universal joint structure.

[0076] Beneficial effects: The inner support rod and the cleaning head are connected by a second universal joint structure, which makes it convenient for users to clean the hard-to-reach areas of the item to be cleaned by operating the handle, resulting in better cleaning effect.

[0077] In one optional implementation, the second universal joint structure includes:

[0078] The second connecting block is rotatably connected to the cleaning head, and the second connecting block is adapted to rotate in a third rotation direction;

[0079] The end of the inner strut is rotatably connected to the second connecting block. The inner strut is adapted to rotate in a fourth rotation direction, and the fourth rotation direction is perpendicular to the third rotation direction.

[0080] Beneficial effects: The second connecting block is connected to the cleaning head and the inner support rod in the above manner, which allows the cleaning head to rotate 360° relative to the inner support rod, resulting in a larger cleaning range, more flexible cleaning operation, and better cleaning of hard-to-reach areas.

[0081] In one alternative embodiment, a connector is threaded onto the end of the inner strut, and the connector is provided with a second rotating connection portion adapted to rotatably connect with the second connecting block.

[0082] Beneficial effects: The connector threaded to the end of the inner strut facilitates disassembly and assembly, and also makes it easy to achieve a rotatable connection with the second connecting block. Since the entire inner strut is relatively long, the added connector facilitates the processing of the second rotatable connection part.

[0083] In one alternative implementation, the inner support rod is detachably connected to the cleaning head.

[0084] Beneficial benefits: The internal support rod and cleaning head are designed with a detachable connection, making it easy to separate the internal support rod, cleaning head, and handle when not in use, and facilitating storage.

[0085] In one alternative implementation, one end of the inner strut is secured to the cleaning head via a clamping sleeve to form a detachable connection.

[0086] Beneficial effects: The inner support rod and the cleaning head are detachably connected by a clamping sleeve, which is simple in structure and makes disassembly and assembly more convenient and efficient. The inner cleaning head and handle can be detached from the inner support rod as a whole through the clamping sleeve, making this part interchangeable with existing single-sided glass wipers with rods, thus improving the utilization rate of existing products.

[0087] In one alternative embodiment, when the inner support rod is connected to the cleaning head via a second universal joint structure, the second universal joint structure including a second connecting block, the second connecting block is hinged to the clamping sleeve to achieve a rotatable connection with the cleaning head.

[0088] Beneficial effects: The second connecting block is hinged to the clamping sleeve, so that the inner support rod, the second universal connecting structure and the clamping sleeve form a combined structure. Thus, the inner support rod can be separated from the cleaning head and handle by disassembling and assembling the snap-fit ​​sleeve, which is more convenient and efficient.

[0089] In one alternative implementation, the cleaning head includes:

[0090] Cleaning head body;

[0091] The cleaning head connecting rod is hinged to the cleaning head body;

[0092] The handle is fixedly connected to the cleaning head linkage, and the inner support rod is connected to the cleaning head linkage.

[0093] Beneficial effects: The cleaning head body and the cleaning head connecting rod are connected by a hinge, which makes the cleaning head body more flexible and convenient for cleaning hard-to-reach areas.

[0094] In one alternative embodiment, the handle and the cleaning head linkage are fixedly connected by a connecting elbow, and the inner support rod is clamped onto the connecting elbow by a clamping sleeve to form a detachable connection with the cleaning head.

[0095] Beneficial effects: Connecting the handle and cleaning head rod via the connecting elbow creates a set angle between them, facilitating handle operation and reducing the space occupied by the entire double-sided cleaning device. Furthermore, the clamping sleeve, secured to the connecting elbow, allows the handle, connecting elbow, and inner cleaning head to be detached as a whole from the inner support rod. This makes this part interchangeable with existing single-sided glass wipers with rods, improving the utilization rate of existing products.

[0096] In one alternative implementation, the cleaning head is fixedly connected to the external support rod.

[0097] Beneficial effects: The outer cleaning head is directly fixed to the outer support rod, without the need for a universal joint, making the connection simple and reliable. Attached Figure Description

[0129] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0130] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0131] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0132] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0133] The double-sided glass cleaner provided in the related technology uses a U-shaped rod with cleaning heads at both ends to clean both sides of the glass at the same time. However, this type of glass cleaner requires the user to lift the entire glass cleaner with the handle to clean it, which is quite strenuous. Especially when the cleaning head is wet or has a water storage device, the weight of the entire glass cleaner is quite heavy. Users are easily fatigued by holding a heavy glass cleaner for a long time, and it is also troublesome to clean glass of different thicknesses and different parts of the glass.

[0134] The following is combined Figures 1 to 14 The following describes embodiments of the present invention.

[0135] According to an embodiment of the present invention, the present invention provides a double-sided cleaning device 100, including: a cleaning head 10, a handle 20, an inner support rod 30 and an outer support rod 40, and an adjustable fixing device 50.

[0136] Specifically, the cleaning head 10 has two sets, which are respectively located on the inner and outer sides of the part to be cleaned 200; the handle 20 is connected to the cleaning head 10 located on the inner side of the part to be cleaned 200; one end of the inner support rod 30 and the outer support rod 40 are respectively connected to one set of cleaning heads 10, and the other end is connected to each other; the adjustable fixing device 50 is suitable for adjustable fixing at different positions of the part to be cleaned 200; the adjustable fixing device 50 is rotatably connected to both the inner support rod 30 and the outer support rod 40, so that when the handle 20 drives the cleaning head 10 located on the inner side of the part to be cleaned 200 to move along the inner side of the part to be cleaned 200, the inner support rod 30 rotates around the adjustable fixing device 50, and the outer support rod 40 rotates accordingly, thereby driving the cleaning head 10 located on the outer side of the part to be cleaned 200 to move synchronously.

[0137] In the above embodiments, the double-sided cleaning device 100, through the adjustable fixing device 50, can be fixed at different positions on the part to be cleaned 200, preventing it from falling off. This facilitates cleaning different positions on the part to be cleaned 200, and the part to be cleaned 200 can support the weight of the double-sided cleaning device 100. This allows the user to simply hold the handle 20 and operate the handle 20 to simultaneously rotate the inner and outer cleaning heads 10 to clean both sides of the part to be cleaned 200 synchronously. It is relatively lightweight and convenient to use. The user does not need to hold the double-sided cleaning device 100 continuously, as the double-sided cleaning device 100 can be stably maintained at a preset height position, reducing the user's labor intensity and improving the user experience. This effectively solves the problem of existing double-sided glass cleaners that require the user to hold the entire glass cleaner continuously, leading to fatigue and high labor intensity.

[0138] Furthermore, in this embodiment, the adjustable fixing device 50 can not only be used to fix the entire double-sided cleaning device 100, but also its two ends are rotatably connected to the inner support rod 30 and the outer support rod 40 respectively. The adjustable fixing device 50 is connected in the middle position between the inner support rod 30 and the outer support rod 40. In this way, when cleaning the part to be cleaned 200, you only need to hold the handle 20 and move the handle 20 to clean the glass on the arc surface with the connection point between the adjustable fixing device 50 and the inner support rod 30 and the outer support rod 40 as the center and the distance from the connection point to the cleaning head 10 as the radius. This not only has a large cleaning range, but also has the advantages of flexible movement and not easy to fall off.

[0139] It should be noted that the double-sided cleaning device 100 provided in this embodiment can be a glass cleaner, a door cleaner, or a wall cleaner, etc. The item to be cleaned 200 can correspond to glass, a door, or a wall, etc., and this embodiment does not limit it.

[0140] Preferably, in this embodiment, the double-sided cleaning device 100 is a double-sided glass cleaner, the item to be cleaned 200 is glass, and the cleaning head 10 is a glass cleaner. The specific implementation method of this embodiment and the accompanying drawings are also described using the double-sided cleaning device 100 as a glass cleaner and the item to be cleaned 200 as glass.

[0141] The following is combined Figure 1 , Figure 2 , Figures 4 to 7 , Figure 9 , Figure 10 , Figure 12 In this embodiment, the specific method by which the adjustable fixing device 50 rotates simultaneously with the inner support rod 30 and the outer support rod 40 will be described.

[0142] In some embodiments, the adjustable fixing device 50 is provided with rotating connection components 51 on both sides. The inner support rod 30 and the outer support rod 40 are rotatably connected to the adjustable fixing device 50 through a rotating connection component 51, and the direction of the rotation axis is a first direction perpendicular to the inner or outer side of the part to be cleaned 200.

[0143] In the above embodiment, by providing rotating connecting components 51 on both sides of the adjustable fixing device 50, the inner support rod 30 and the outer support rod 40 can be rotatably connected to the adjustable fixing device 50, thereby enabling the cleaning head 10 to rotate. The rotation axis of the rotating connecting component 51 and the adjustable fixing device 50 is perpendicular to the inner or outer side of the part to be cleaned 200, thus achieving the technical effect of moving the cleaning head 10 along the surface of the part to be cleaned 200 for wiping and cleaning.

[0144] Furthermore, in some embodiments, the rotating connection assembly 51 includes a connecting seat 511 and a rotating shaft 512. The connecting seat 511 has a cavity and is connected to the inner support rod 30 or the outer support rod 40 on one side. One end of the rotating shaft 512 is rotatably limited within the connecting seat 511, and the other end is limited and cooperated with the adjustable fixing device 50 to limit the rotation of the rotating shaft 512 along the first direction.

[0145] In the above embodiments, the rotating connection assembly 51 adopts a design of a connecting seat 511 and a rotating shaft 512. The connecting seat 511 is connected to the inner support rod 30 and the outer support rod 40 and can rotate under the drive of the inner support rod 30 and the outer support rod 40. The rotating shaft 512 is designed with one end limited by the adjustable fixing device 50 and the other end rotatably limited by the connecting seat 511. This design ensures that the connecting seat 511 will not drive the rotating shaft 512 to rotate when it rotates, and can rotate freely relative to the rotating shaft 512. This allows the inner support rod 30 and the outer support rod 40 to rotate freely relative to the adjustable fixing device 50.

[0146] Specifically, one end of the rotating shaft 512 is movably connected to the adjustable fixing device 50, and the other end is limited in the connecting seat 511. The connecting seat 511 can rotate freely relative to the rotating shaft 512 in the first direction, while the rotating shaft 512 will not rotate in the first direction under the limitation of the adjustable fixing device 50. The rotating shaft 512 serves to connect the stationary adjustable fixing device 50 and the moving connecting seat 511.

[0147] Furthermore, in some embodiments, the rotating shaft 512 includes a shaft body 5121 and a limiting disk 5122 fixedly disposed at one end of the shaft body 5121. The limiting disk 5122 is confined within the connecting seat 511, and the other end of the shaft body 5121 extends out of the connecting seat 511 and is connected to the adjustable fixing device 50. The connecting seat 511 includes a detachably connected seat body 5111 and a cover body 5112. The seat body 5111 and the cover body 5112 are interlocked and enclosed to form a cavity that can accommodate the limiting disk 5122.

[0148] In the above embodiments, the rotating shaft 512 is designed with a shaft body 5121 and a limiting disk 5122 fixedly disposed at one end of the shaft body 5121. The cross-sectional area of ​​the limiting disk 5122 is larger than that of the shaft body 5121. The limiting disk 5122 is limited in the cavity of the connecting seat 511 and can rotate freely in the cavity. While realizing the rotational connection between the rotating shaft 512 and the connecting seat 511, it can also effectively prevent the connecting seat 511 from separating from the rotating shaft 512. The connecting seat 511 is designed with a detachable seat body 5111 and a cover body 5112, which facilitates the assembly and connection between the rotating shaft 512 and the connecting seat 511.

[0149] In other alternative embodiments, the limiting plate 5122 may also be a limiting boss, a limiting plate, a limiting block, etc., or the rotating shaft 512 and the connecting seat 511 may be connected by a part such as a bearing. This embodiment does not limit this.

[0150] Furthermore, in some embodiments, the other end of the shaft 5121 is movably connected to the adjustable fixing device 50. The movable connection design can effectively prevent the inner support rod 30 and the outer support rod 40 from causing the adjustable fixing device 50 to move relative to the part to be cleaned 200 when they rotate, thus affecting the stability of the position of the adjustable fixing device 50 on the part to be cleaned 200 and consequently affecting the cleaning effect.

[0151] Furthermore, in some embodiments, the base 5111 and the cover 5112 are connected by screws. The connection between the base 5111 and the cover 5112 by screws is reliable, stable, and easy to assemble and disassemble.

[0152] Of course, in other alternative embodiments, the base 5111 and the cover 5112 can also be snapped together, and this embodiment does not limit this.

[0153] In this embodiment, the rotating connection assembly 51 includes a connecting seat 511 and a rotating shaft 512. The connecting seat 511 includes a seat body 5111 and a cover body 5112. The interior of the seat body 5111 has a recess with an open side. The cover body 5112 covers the open side of the seat body 5111 and together with the seat body 5111, forms a cavity that can accommodate the limiting disk 5122. The rotating shaft 512 includes a limiting plate 5122 and a shaft body 5121. The limiting plate 5122 is located inside the connecting seat 511. The seat body 5111 is located on the side near the adjustable fixing device 50. The cover 5112 is located on the side near the inner support rod 30 and the outer support rod 40. The seat body 5111 and the cover 5112 can be fastened together and connected by screws. The cavity formed after fastening can accommodate the limiting plate 5122. The shaft body 5121 passes through the seat body 5111, so that the connecting seat 511 formed after the seat body 5111 and the cover 5112 are fastened together can rotate relative to the rotating shaft 512 without causing the rotating shaft 512 to detach from the connecting seat 511.

[0154] Combination Figure 1 , Figure 2 , Figures 4 to 6 , Figure 11 The linkage method of synchronous movement of the inner support rod 30 and the outer support rod 40 in this embodiment will be described in detail.

[0155] In some embodiments, the inner support rod 30 and the outer support rod 40 are hinged to each other at the ends away from the cleaning head 10. The adjustable fixing device 50 includes a linkage mechanism 52, which is driven between the inner support rod 30 and the outer support rod 40 so that the two can simultaneously move closer to or further away from the part to be cleaned 200.

[0156] In the above embodiment, the ends of the inner support rod 30 and the outer support rod 40 furthest from the cleaning head 10 are connected by a hinge. The linkage mechanism 52, which connects the inner support rod 30 and the outer support rod 40, allows the outer support rod 40 to rotate as the inner support rod 30 rotates along the inner glass surface. When the inner support rod 30 moves away from the inner glass surface, the hinge point forms a fulcrum, and the linkage mechanism 52 pushes the outer support rod 40 away from the outer glass surface. This allows the two cleaning heads 10 to simultaneously move away from or near the inner and outer surfaces of the glass, achieving synchronous cleaning. Furthermore, the hinged connection between the inner support rod 30 and the outer support rod 40 ensures reliable connection and stable linkage, making the distance between them adjustable to accommodate glass of different thicknesses. It also effectively avoids structural damage caused by rigid connections.

[0157] Specifically, the ends of the inner support rod 30 and the outer support rod 40 furthest from the cleaning head 10 are connected by a hinge structure 90, making the linkage more stable.

[0158] Of course, in other alternative implementations, the ends of the inner support rod 30 and the outer support rod 40 away from the cleaning head 10 may not be connected by a hinge. For example, they may be connected by a hose or fixed connection. When the ends of the inner support rod 30 and the outer support rod 40 are fixedly connected, both the inner support rod 30 and the outer support rod 40 must have a certain bending deformation capability to match glass of different thicknesses.

[0159] Furthermore, in some embodiments, the adjustable fixing device 50 includes a support body 500, and the linkage mechanism 52 includes a parallel four-bar linkage 521. The parallel four-bar linkage 521 includes two first links 5211 and two second links 5212 arranged parallel to each other. The middle part of the first link 5211 is hinged to the support body 500, and both ends are respectively hinged to the two second links 5212. The linkage mechanism 52 also includes two transition links 522. One end of the two transition links 522 is respectively hinged to the diagonal of the parallel four-bar linkage 521, and the other end is respectively movably connected to the inner support rod 30 and the outer support rod 40.

[0160] In the above embodiment, the linkage mechanism 52 adopts a design of parallel four-bar linkage 521 and two transition links 522, which has a simple structure, high stability, low cost, and high reliability of force transmission. The two transition links 522 are connected at opposite corners of the parallel four-bar linkage 521, making it easier to pull the parallel four-bar linkage 521 to move, further improving the reliability and synchronization of motion transmission between the inner support rod 30 and the outer support rod 40.

[0161] Specifically, the two first links 5211 are parallel to each other, and the two second links 5212 are parallel to each other. The ends of the two first links 5211 are hinged to the two second links 5212 respectively, forming a parallelogram structure. The middle part of the first link 5211 is hinged to the support body 500 to ensure the stability of the entire linkage mechanism 52 during movement. One end of the two transition links 522 is hinged to the ends of the first link 5211 and the second link 5212 located at opposite corners of the parallel four-bar linkage 521. Specifically, the parallel four-bar linkage 521 includes a first hinge end and a second hinge end located at one of the diagonal ends. The two transition links 522 are hinged to the ends of the first link 5211 and the second link 5212 located at the first hinge end and the second hinge end respectively, thereby realizing the hinge between the two transition links 522 and the entire parallel four-bar linkage 521. All links are connected by hinges, which makes the entire linkage mechanism 52 more flexible and less prone to jamming during movement.

[0162] In some embodiments, two hinge shafts 501 are fixedly provided on the support body 500, and the middle of the two first connecting rods 5211 is provided with shaft holes corresponding to the two hinge shafts 501 respectively.

[0163] In the above embodiment, the first connecting rod 5211 is connected to the hinge shaft 501 on the support body 500 by means of opening a shaft hole, so as to realize the rotational connection between the first connecting rod 5211 and the support body 500. The connection structure is simple and easy to process and form.

[0164] In some modified embodiments, a hinge shaft 501 may be fixedly installed at the middle of the first connecting rod 5211, and a shaft hole that mates with the hinge shaft 501 may be opened on the support body 500.

[0165] In some embodiments, the adjustable fixing device 50 further includes a first limiting member 502 and a second limiting member 503, which are fixedly disposed on the support body 500 and respectively disposed on both sides of one of the first connecting rods 5211, for limiting the stroke of the first connecting rod 5211.

[0166] In the above embodiment, by providing a first limiting member 502 and a second limiting member 503 on both sides of the first link 5211, the first limiting member 502 and the second limiting member 503 can limit the stroke of the first link 5211, preventing the first link 5211 from rotating too much, so that the linkage mechanism 52 can interfere with or conflict with other components.

[0167] For example, the first limiting member 502 is disposed on the inner side of the parallel four-bar linkage 521, and the second limiting member 503 is disposed on the outer side of the parallel four-bar linkage 521. The first limiting member 502 and the second limiting member 503 are disposed on both sides of a first link 5211. The first limiting member 502 can effectively prevent the transition link 522 from colliding with the support body 500, and the second limiting member 503 can effectively prevent the seat 5111 of the connecting seat 511 from colliding with the outer wall of the support body 500.

[0168] In some embodiments, the first limiting member 502 and the second limiting member 503 are limiting pins fixedly disposed on the support body 500.

[0169] In the above embodiments, the first limiting member 502 and the second limiting member 503 adopt the structure of limiting pins, which is simple in structure. The outer peripheral surface of the limiting pin is circular, which can effectively limit the stroke of the first connecting rod 5211 while forming a point-line contact with the first connecting rod 5211. The contact area is small and the friction is small.

[0170] Of course, in other alternative implementations, the first limiting member 502 and the second limiting member 503 may also adopt structural forms such as limiting post, limiting block, and limiting plate.

[0171] In some embodiments, when the adjustable fixing device 50 is provided with a rotating connection assembly 51 on both sides, and the rotating connection assembly 51 includes a connecting seat 511 and a rotating shaft 512, one end of the rotating shaft 512 is rotatably limited in the connecting seat 511, and the other end is hinged to the end of the transition link 522 away from the parallel four-bar linkage 521.

[0172] In the above embodiment, one end of the rotating shaft 512 is rotatably limited within the connecting seat 511, and the other end is connected to the adjustable fixing device 50 by means of hinged connection between the rotating shaft 512 and the transition connecting rod 522. This achieves a movable connection between the rotating shaft 512 and the linkage mechanism 52, avoiding structural damage caused by hard connection, while also improving the force transmission effect.

[0173] In this embodiment, the ends of the rotating shaft 512 and the transition link 522 are respectively provided with shaft holes, and the ends of the first link 5211 and the second link 5212 are also respectively provided with shaft holes. The hinges between the rotating shaft 512 and the transition link 522, the first link 5211 and the second link 5212, and the transition link 522 and the first link 5211 and the second link 5212 are respectively realized by pins.

[0174] In this embodiment, the rotating shaft 512 is hinged to the linkage mechanism 52. The inner support rod 30 and the outer support rod 40 are linked together through the hinge between the rotating shaft 512 and the linkage mechanism 52. The linkage mechanism 52 mainly includes two transition links 522, two first links 5211, and two second links 5212. The two second links 5212 and the two first links 5211 form a parallelogram structure. Each first link 5211 is hinged to the support body 500 in the middle and to the two second links 5211 at both ends. The second link 5212 is hinged. At two opposite corners of the parallelogram, the first link 5211, the second link 5212, and the transition link 522 are hinged. The support body 500 is also fixedly provided with a first limit pin and a second limit pin. The first limit pin and the second limit pin are respectively located on both sides of a first link 5211 to limit the stroke of the first link 5211 and prevent the first link 5211 from rotating too much, which would cause the linkage mechanism 52 to conflict and interfere with other parts.

[0175] In some embodiments, the support body 500 is a hollow shell structure with an internal cavity, the linkage mechanism 52 is disposed in the cavity, and the opposite side walls of the support body 500 are respectively provided with through holes through which the rotating shaft 512 can pass.

[0176] In the above embodiment, the support body 500 adopts a hollow shell structure design and sets the linkage mechanism 52 inside the support body 500, thereby hiding the linkage mechanism 52 and improving its aesthetics. At the same time, the support body 500 can also protect the linkage mechanism 52, preventing the linkage mechanism 52 from interfering with external components or accumulating dust during movement.

[0177] Of course, in other alternative implementations, the support body 500 may also adopt a plate-like or block-like structural design.

[0178] In some embodiments, the support body 500 includes a first housing 504 and a second housing 505 that are fastened together; the first housing 504 and the second housing 505 are respectively provided with two opening slots on both sides. After the first housing 504 and the second housing 505 are fastened together, the two opening slots on the first housing 504 and the second housing 505 are joined together to form two through holes for the rotating shaft 512 to pass through.

[0179] In the above embodiment, the support body 500 adopts a design of interlocking first housing 504 and second housing 505, which facilitates the disassembly and assembly of the internal linkage mechanism 52. The through hole formed by splicing the opening slots on the first housing 504 and the second housing 505 is more convenient for the installation of the rotating shaft 512 than a one-piece molded circular through hole. During assembly, the rotating shaft 512 is first placed in the opening slot on the first housing 504, and then the second housing 505 is fastened to the first housing 504, which improves the assembly efficiency.

[0180] Specifically, the support body 500 includes a first end sidewall near the inner support rod 30 and a second end sidewall near the outer support rod 40. The first end sidewall and the second end sidewall are respectively provided with through holes. The first end sidewall and the second end sidewall are formed by splicing the end walls of the first housing 504 and the second housing 505. Semi-circular holes are respectively provided on the mating edges of the end walls of the first housing 504 and the second housing 505. The two semi-circular holes form a complete circular through hole after the first housing 504 and the second housing 505 are fastened together.

[0181] In some embodiments, semi-cylindrical guide ribs are fixedly provided on the outer sides of the two opening slots of the first housing 504 and the second housing 505, respectively. After the first housing 504 and the second housing 505 are fastened together, the two semi-cylindrical guide ribs enclose and form a cylindrical guide channel. The guide channel can guide the rotating shaft 512 to move in the thickness direction of the part to be cleaned, thereby realizing the synchronous movement of the inner support rod and the outer support rod 40 located on the inner and outer sides of the glass through the linkage mechanism 52.

[0182] In some embodiments, the inner diameter of the through hole is larger than the outer diameter of the shaft 5121 of the rotating shaft 512. This design makes it easier to install the rotating shaft 512, and also ensures that the rotating shaft 512 can extend and retract in the axial direction of the through hole to drive the linkage mechanism 52 to move, thereby realizing the synchronous movement between the inner support rod 30 and the outer support rod 40.

[0183] In some embodiments, the first housing 504 and the second housing 505 are fastened together and secured by screws.

[0184] In the above embodiments, the first housing 504 and the second housing 505 are connected by screws, which makes the connection reliable, stable and easy to disassemble and assemble.

[0185] Specifically, in this embodiment, the first housing 504 is located on the side close to the cleaning head 10. Two hinge pins 501 are fixedly provided on the inner wall of the first housing 504 for rotatably connecting with two first connecting rods 5211 respectively. The first housing 504 and the second housing 505 are respectively provided with two opening slots. When the two housings are fastened together, the opening slots form two through holes for the two shafts 5121 to pass through. The shafts 5121 can slide in the through holes. The two housings are locked together by screws.

[0186] In some embodiments, the two sides of the adjustable fixing device 50 are respectively connected to the inner support rod 30 and the outer support rod 40 via the first universal joint structure 60.

[0187] In the above embodiment, through the first universal connection structure 60, when the linkage mechanism 52 is activated, the inner support rod 30 and the outer support rod 40 can rotate relative to the supporting body 500. When the handle 20 is rotated to move the cleaning head 10, it facilitates the rotation of the inner support rod 30 and the outer support rod 40.

[0188] In some embodiments, the first universal joint structure 60 is slidably connected to the inner support rod 30 and the outer support rod 40. By sliding the first universal joint structure 60 to the inner support rod 30 and the outer support rod 40, the distance between the cleaning head 10 and the adjustable fixing device 50 can be adjusted by adjusting the position of the first universal joint structure 60 on the inner support rod 30 and the outer support rod 40. This allows for adjustment of the cleaning radius of the cleaning head 10, enabling cleaning of the parts 200 to be cleaned within different radius ranges of the adjustable fixing device 50.

[0189] Specifically, in some embodiments, the first universal joint structure 60 includes a sliding sleeve 61 and a first connecting block 62. The sliding sleeve 61 is slidably sleeved on the inner support rod 30 and the outer support rod 40. The first connecting block 62 is adapted to be rotatably connected to the sliding sleeve 61 in a first rotation direction. The adjustable fixing device 50 is provided with a rotating connecting component 51 at both ends. The rotating connecting component 51 is adapted to be rotatably connected to the first connecting block 62 in a second rotation direction. The first rotation direction is perpendicular to the second rotation direction.

[0190] In the above embodiments, the first universal connection structure 60 employs a sliding sleeve 61 design. The sliding sleeve 61 is slidably fitted onto the inner support rod 30 and the outer support rod 40. The sliding connection method is relatively simple. When it is desired to adjust the cleaning radius, the position of the sliding sleeve 61 on the inner support rod 30 and the outer support rod 40 can be adjusted to achieve the adjustment of the cleaning radius of the cleaning head 10, so as to clean the parts 200 to be cleaned within different radius ranges of the adjustable fixing device 50. In addition, the first connecting block 62 is connected to the sliding sleeve 61, and the first connecting block 62 is connected to the rotating connection assembly 51 in the above manner, so that the inner support rod 30 and the outer support rod 40 can rotate 360°, resulting in a larger cleaning range and greater practicality.

[0191] Specifically, the inner diameter of the sliding sleeve 61 is slightly larger than the outer diameter of the inner support rod 30 and the outer support rod 40, and it has a short cylindrical structure, which is sleeved on the inner support rod 30 and the outer support rod 40. The first connecting block 62 has a directional block structure, and the first connecting block 62 includes two first sidewalls located on the left and right sides. A first rotating shaft is fixedly installed on each of the two first sidewalls. Two opposing first connecting plates are fixedly installed on the side of the sliding sleeve 61 near the rotating connecting assembly 51, and the two first rotating shafts are rotatably connected between the two first connecting plates. The central axis of the first rotating shaft is parallel to the central axis of the main body of the inner support rod 30 and the outer support rod 40.

[0192] Furthermore, the first connecting block 62 also includes two second sidewalls located on the upper and lower sides, and a second rotating shaft is fixedly installed on each of the two second sidewalls. The central axis of the second rotating shaft is perpendicular to the axial direction of the inner support rod 30 and the outer support rod 40, and the central axis of the second rotating shaft is parallel to the cleaning surface of the part to be cleaned 200.

[0193] In some embodiments, when the rotary connection assembly 51 includes a connecting seat 511 and a rotating shaft 512, the side of the connecting seat 511 away from the rotating shaft 512 is provided with a first rotary connection portion 5113 that is rotatably connected to the first connecting block 62.

[0194] In the above embodiment, the first rotating connection part 5113 is provided to realize the rotating connection between the rotating connection assembly 51 and the first connecting block 62, thereby realizing the connection between the inner support rod 30 and the outer support rod 40 and the adjustable fixing device 50.

[0195] Specifically, the first rotating connection part 5113 is fixedly installed at the center of the outer wall of the cover 5112. The first rotating connection part 5113 includes two connecting ribs that are opposite to each other and spaced apart. The two connecting ribs are respectively provided with shaft holes that connect to the two second rotating shafts on the first connecting block 62. The distance between the two connecting ribs is greater than the thickness of the first rotating block, so as to avoid the first rotating block.

[0196] In this embodiment, the inner support rod 30 and the outer support rod 40 are respectively connected to the rotary connection assembly 51 through the first universal joint structure 60 (i.e., universal joint). The first universal joint structure 60 includes a cross block and a sliding sleeve 61. The sliding sleeve 61 is slidably connected to the inner support rod 30 and the outer support rod 40. The side of the sliding sleeve 61 closest to the rotary connection assembly 51 is rotatably connected to the first rotation axis of the cross block. The second rotation axis of the cross block is rotatably connected to the rotary connection assembly 51.

[0197] In some embodiments, the lengths of the inner strut 30 and the outer strut 40 are adjustable.

[0198] In the above embodiments, the inner support rod 30 and the outer support rod 40 are designed to be adjustable in length, so that the position of the cleaning head 10 relative to the adjustable fixing device 50 in the length direction of the inner support rod 30 and the outer support rod 40 can be adjusted, thereby adjusting the cleaning radius of the cleaning head 10.

[0199] In some embodiments, the inner support rod 30 and the outer support rod 40 are telescopic rods or multi-segment rods with threaded connections.

[0200] In the above embodiments, the inner support rod 30 and the outer support rod 40 adopt a telescopic rod or a multi-segment rod structure with threaded connection, which facilitates the adjustment of the position of the cleaning head 10 relative to the adjustable fixing device 50 in the length direction of the inner support rod 30 and the outer support rod 40.

[0201] In this embodiment, the inner support rod 30 and the outer support rod 40 can be connected by a multi-section detachable rod connection, or they can be connected by a telescopic sleeve rod.

[0202] In some embodiments, the adjustable fixing device 50 is adsorbed or clamped onto the part to be cleaned 200.

[0203] In the above embodiments, the adjustable fixing device 50 is adsorbed or clamped onto the part to be cleaned 200, which facilitates the installation and removal of the adjustable fixing device 50 and also facilitates the adjustment of the fixing position of the adjustable fixing device 50 on the part to be cleaned 200.

[0204] In this embodiment, the adjustable fixing device 50 is clamped onto the window frame 201. Alternatively, a suction cup or other method can be used, as long as the adjustable fixing device 50 can be fixed onto the window glass.

[0205] In some embodiments, combined with Figure 1 , Figure 2 , Figures 4 to 7 , Figures 9 to 11 As shown, the adjustable fixing device 50 is clamped and fixed on the workpiece 200 to be cleaned by the clamping mechanism 53. The clamping mechanism 53 includes a clamping member 531 and a locking member 532. The clamping member 531 has two members arranged opposite to each other. The locking member 532 is disposed on the clamping member 531. The locking member 532 is used to adjust the clamping degree of the clamping mechanism 53 when the two clamping members 531 are clamped on the workpiece 200 to be cleaned, so as to accommodate workpieces 200 of different thicknesses.

[0206] In the above embodiment, the adjustable fixing device 50 is movably connected to the inner support rod 30 and the outer support rod 40 on both sides, and the clamping mechanism 53 is clamped on the fixed object. The clamping mechanism 53 adopts the design of clamping member 531 and locking member 532. The two clamping members 531 can clamp on the part to be cleaned 200, and the locking member 532 can adjust the clamping degree of the clamping mechanism 53, so as to conveniently adapt to the part to be cleaned 200 of different thicknesses.

[0207] In some embodiments, the clamping member 531 is a clamping plate, and the locking member 532 includes a locking bolt 5321 threadedly connected to the clamping plate; one end of the locking bolt 5321 is adapted to pass through the clamping plate and abut against the part 200 to be cleaned, and the other end is fixedly provided with a knob 5322.

[0208] In the above embodiment, the locking member 532 adopts the structure of a locking bolt 5321, and the fixing is achieved by the abutment force between the end of the locking bolt 5321 and the part to be cleaned 200. The structure is simple, and the connection has high stability and reliability. It also facilitates the adjustment of the clamping degree of the clamping mechanism 53. For example, when the clamping position of the part to be cleaned 200 is thick, the locking bolt 5321 is screwed outward so that the distance between the end of the locking bolt 5321 and the symmetrical clamping plate matches the thickness of the clamping position of the part to be cleaned 200 to achieve fixing. When the clamping position of the part to be cleaned is thin, the locking bolt 5321 is screwed inward so that the end of the locking bolt 5321 is tightly abutted against the part to be cleaned 200 to achieve fixing. Moreover, the knob 5322 is provided to make the screwing operation more convenient.

[0209] In some embodiments, the locking member 532 is disposed on the clamping member 531 located inside the part to be cleaned 200.

[0210] In the above embodiment, by setting the locking member 532 on the clamping member 531 located inside the part to be cleaned 200, it is more convenient for the user to perform the adjustment operation while standing indoors compared to setting it on the outside of the part to be cleaned 200.

[0211] Preferably, in this embodiment, the component 200 to be cleaned includes a main body and a frame, and the clamping mechanism 53 clamps the outer frame of the component 200. For example, the component 200 to be cleaned is glass, the main body is a glass body, the frame is a window frame 201, and the clamping mechanism 53 clamps the glass window frame 201.

[0212] Specifically, in this embodiment, a U-shaped clamping mechanism 53 is fixedly provided on the side wall of the first housing 504 near the window frame 201. The clamping mechanism 53 includes two clamping plates arranged opposite each other, and a locking member 532 is installed on the clamping plates. When the U-shaped clamping mechanism 53 is clamped on the window frame 201, the clamping degree can be adjusted by operating the knob 5322 to adapt to window frames 201 of different thicknesses.

[0213] The following is combined Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 9 , Figure 13 , Figure 14 As shown, the connection method between the cleaning head 10 and the inner support rod 30 in this embodiment will be described.

[0214] In this embodiment, the inner support rod 30 is connected to the cleaning head 10 through the second universal joint structure 70.

[0215] In the above embodiment, the inner support rod 30 and the cleaning head 10 are connected by the second universal connection structure 70, which makes it convenient for the user to clean the dead corners and other areas of the part to be cleaned 200 by operating the handle 20, resulting in a better cleaning effect.

[0216] In some embodiments, the second universal joint structure 70 includes a second connecting block 71, which is rotatably connected to the cleaning head 10 and is adapted to rotate in a third rotation direction; the end of the inner support rod 30 is rotatably connected to the second connecting block 71 and is adapted to rotate in a fourth rotation direction, which is perpendicular to the third rotation direction.

[0217] In the above embodiment, the second connecting block 71 is connected to the cleaning head 10 and the inner support rod 30 in the above manner, so that the cleaning head 10 can rotate 360° relative to the inner support rod, resulting in a larger cleaning range, more flexible cleaning operation, and better cleaning of dead corners.

[0218] In some embodiments, a connector 72 is threaded to the end of the inner support rod 30, and a second rotating connection portion 721 adapted to be rotatably connected to the second connecting block 71 is provided on the connector 72.

[0219] In the above embodiment, the connector 72 threaded to the end of the inner support rod 30 facilitates disassembly and assembly, and also facilitates rotational connection with the second connecting block 71. Since the entire inner support rod 30 is relatively long, the added connector 72 facilitates the processing of the second rotating connection part 721.

[0220] Specifically, the second rotating connection part 721 includes a U-shaped connecting body formed on the connector 72, and shaft holes suitable for connecting with the second connecting block 71 are respectively provided on the opposite side walls of the U-shaped connecting body. The specific structure of the second connecting block 71 and the rotation method of the cleaning head 10 and the connector 72 are similar to those of the first connecting block 62, and will not be described again here.

[0221] In some embodiments, the inner support rod 30 is detachably connected to the cleaning head 10.

[0222] In the above embodiments, the inner support rod 30 and the cleaning head 10 are designed to be detachably connected, which makes it easy to separate the inner support rod 30, the cleaning head 10 and the handle 20 when not in use, and facilitates storage.

[0223] In some embodiments, one end of the inner support rod 30 is secured to the cleaning head 10 by a clamping sleeve 73 to form a detachable connection.

[0224] In the above embodiment, the inner support rod 30 and the cleaning head 10 are detachably connected by a clamping sleeve 73. The structure is simple and the disassembly and assembly are more convenient and efficient. The inner cleaning head 10 and handle 20 can be detached from the inner support rod 30 as a whole through the clamping sleeve 73, so that this part can be interchanged with the existing single-sided glass wiper with a rod, thereby improving the utilization rate of the existing product.

[0225] Specifically, the clamping sleeve 73 has a U-shaped clamping body. The U-shaped clamping body includes an arc-shaped sleeve portion whose inner circumference matches the outer circumference of the inner support rod 30. The corresponding central angle is greater than 180° to prevent the clamping sleeve 73 from separating from the inner support rod 30. The gap distance between the two ends of the arc-shaped sleeve portion is smaller than the diameter of the inner support rod 30, which can effectively prevent the clamping sleeve 73 from separating from the inner support rod 30 and improve the stability after the clamping sleeve 73 and the inner support rod 30 are engaged.

[0226] Preferably, the U-shaped clamping body further includes two guide parts fixedly disposed at both ends of the arc-shaped sleeve portion, wherein the distance between the two guide parts gradually increases from the arc-shaped sleeve portion outwards, playing a guiding role and improving assembly efficiency.

[0227] In some embodiments, when the inner support rod 30 is connected to the cleaning head 10 via the second universal joint structure 70, and the second universal joint structure 70 includes a second connecting block 71, the second connecting block 71 is hinged to the clamping sleeve 73 to achieve a rotatable connection with the cleaning head 10.

[0228] In the above embodiment, the second connecting block 71 is hinged to the clamping sleeve 73, so that the inner support rod 30, the second universal connecting structure 70 and the clamping sleeve 73 form a combined structure. Thus, the inner support rod 30 can be separated from the cleaning head 10 and the handle 20 by disassembling and assembling the snap-fit ​​sleeve, which is more convenient and efficient.

[0229] In some embodiments, the cleaning head 10 includes a cleaning head body 11 and a cleaning head connecting rod 12, which are hinged together; the handle 20 is fixedly connected to the cleaning head connecting rod 12, and the inner support rod 30 is connected to the cleaning head connecting rod 12.

[0230] In the above embodiment, the cleaning head body 11 and the cleaning head connecting rod 12 are connected by a hinge, which makes the cleaning head body 11 more flexible and convenient for cleaning dead corners.

[0231] In some embodiments, the handle 20 is fixedly connected to the cleaning head connecting rod 12 via a connecting elbow 80, and the inner support rod 30 is clamped onto the connecting elbow 80 via a clamping sleeve 73 to form a detachable connection with the cleaning head 10.

[0232] In the above embodiment, the handle 20 and the cleaning head connecting rod 12 are connected by a connecting elbow 80, so that the handle 20 and the cleaning head connecting rod 12 are connected at a set angle, which facilitates user operation of the handle 20 and reduces the space occupied by the entire double-sided cleaning device 100. In addition, the clamping sleeve 73 is attached to the connecting elbow 80 by a snap-fit, so that the handle 20, the connecting elbow 80, and the inner cleaning head 10 can be detached from the inner support rod 30 as a whole, so that this part can be interchanged with existing single-sided glass wipers with rods, improving the utilization rate of existing products.

[0233] Specifically, the connecting elbow 80 includes a hollow connecting rod with a set bending angle. The connecting rod includes a first rod body and a second rod body bent at a set angle. The first rod body is fixedly connected to the cleaning head connecting rod 12, and the second rod body is fixedly connected to the handle 20. Optionally, the first rod body and the cleaning head 10, and the second rod body and the handle 20, can be fixedly connected by a plug-in fit for easy assembly and disassembly. The first rod body and the cleaning head connecting rod 12 are on the same axis, and the second rod body and the handle 20 are on the same axis. The clamping sleeve 73 is fitted onto the first rod body near the cleaning head body 11.

[0234] In this embodiment, the inner support rod 30 is connected to the cleaning head 10 and the handle 20 through the second universal connection structure 70 and the connecting elbow 80. One end of the connecting elbow 80 is connected to the cleaning head 10 and the other end is connected to the handle 20. The second universal connection structure 70 includes a clamping sleeve 73, a cross-shaped second connecting block 71, and a connecting head 72. The second connecting block 71 includes two sets of rotating shafts that are perpendicular to each other. The connecting head 72 is threadedly connected to the inner support rod 30, and its other end is rotatably connected to one set of rotating shafts of the second connecting block 71. The other set of rotating shafts of the second connecting block 71 is rotatably connected to the clamping sleeve 73. The clamping sleeve 73 is clamped on the connecting elbow 80 for easy disassembly.

[0235] In some embodiments, combined with Figure 8 , Figure 9 , Figure 11 As shown, the cleaning head 10 is fixedly connected to the outer support rod 40. The outer cleaning head 10 and the outer support rod 40 are directly fixedly connected, without the need for a universal joint, making the connection simple and reliable.

[0236] The double-sided cleaning device 100 provided in this embodiment includes an inner support rod 30, an outer support rod 40, a handle 20, an adjustable fixing device 50, and a cleaning head 10. One end of the inner support rod 30 and the outer support rod 40 are rotatably connected by a hinge structure 90, and the other end is connected to a cleaning head 10. The clamping mechanism 53 is adjustablely clamped to a window frame 201, etc. The inner support rod 30 and the outer support rod 40 are also slidably connected to the adjustable fixing device 50. The adjustable fixing device 50 is connected to the inner support rod 30 and the outer support rod 40 through a rotating connection assembly 51, so that the inner support rod 30 and the outer support rod 40 can drive the cleaning head 10 to rotate relative to the adjustable fixing device 50. The handle 20 is also connected to the inner support rod 30, which is convenient for the user to operate while standing indoors.

[0237] Furthermore, the adjustable fixing device 50, through the design of the clamping mechanism 53, allows the adjustable fixing device 50 to be clamped onto the window frame 201, making it easy to install and remove from the window. Through the linkage mechanism design, the adjustable fixing device 50 allows the internal glass cleaner to be operated via the handle 20, enabling the internal and external glass cleaners to move simultaneously along various directions of the glass surface, facilitating simultaneous cleaning of various parts of the glass. Moreover, the two glass cleaners can simultaneously move closer to or further away from the window to accommodate different glass thicknesses.

[0238] This embodiment takes the double-sided cleaning device 100 for cleaning glass as an example to introduce its usage process, principle and other contents.

[0239] First, the adjustable fixing device 50 is clamped to fixed positions such as the window frame 201, glass, and wall using two clamping plates on the first housing 504. Then, the knob 5322 is adjusted to tighten the clamp, thus fixing the entire device to the building and preventing it from falling. After clamping, the two cleaning heads 10 are positioned on either side of the glass. The user cleans the window by holding the handle 20. Since the cleaning head body 11 and the cleaning head connecting rod 12 are rotatable, the plane of the cleaning head body 11 can be adjusted to be parallel to the glass surface. When rotation is needed, simply hold the handle 20 to clean the glass along an arc formed by the axis 5121 with a radius equal to the distance from the axis 5121 to the cleaning head 10. When cleaning areas of other radii on this arc are needed, the inner support rod 30 and the outer support rod 40 are slid along the sliding sleeve 61. When both cleaning heads 10 are simultaneously approaching or moving away from the glass surface, the user pulls the handle 20 away from the glass surface. The cleaning head 10 on the inner support rod 30 will move away from the glass surface. At the same time, since the inner support rod 30 and the outer support rod 40 can only slide relative to the sliding sleeve 61, the rotating shaft 512 drives the transition connecting rod 522 to rotate, which in turn drives the first connecting rod 5211 and the second connecting rod 5212 of the linkage mechanism 52 to rotate, which in turn drives the transition connecting rod 522 connected to the outer support rod 40 to rotate, which in turn drives the other shaft 5121 to rotate, which in turn drives the outer support rod 40 away from the glass surface, and thus drives the outer cleaning head 10 away from the outer glass surface. Conversely, when it is necessary to bring both cleaning heads 10 close to the glass surface at the same time, they can also be linked in the same way. This makes it easy for the user to adjust the force of cleaning the glass, making it easier and less strenuous to clean glass surfaces with different levels of dirt. Furthermore, the double-sided cleaning device 100 provided in this embodiment can be detached from the inner support rod 30 and the cleaning head 10, thereby achieving compatibility with household glass cleaners with rods, improving the utilization rate of existing products and reducing waste.

[0240] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
