Description

Technical Field

[0001] This technical solution relates to the field of window cleaners, specifically a window cleaner with a rotatable head. Background Art

[0002] A window cleaner is a tool specifically designed for cleaning windows. Its function is to remove dust accumulated on the glass, traces left by rain, stains, and other pollutants. Types of window cleaners include manual, electric, magnetic, and advanced window cleaners, etc., each having different characteristics and application scenarios.

[0003] Currently, there are obstructive factors in the use of existing window cleaners for wiping glass windows. Since glass windows are usually fixed inside the window frame, a cleaning blind spot is formed in the corner area where the edge of the window frame meets the glass. The cleaning is physically obstructed by the window frame structure, and current window cleaners are difficult to reach this corner for cleaning, resulting in incomplete cleaning and poor cleaning effects, which need to be improved. Summary of the Invention

[0004] This technical solution provides a window cleaner with a rotatable head to improve the poor cleaning effect of the window cleaner when wiping the corners of the window frame.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A window cleaner with a rotatable head includes a brush rod, the front end of which has a connecting head;

[0007] A brush plate is arranged at the front end of the brush rod and is rotatably connected relative to the brush rod;

[0008] The brush rod and the brush plate are adjusted by an adjusting structure to realize the adjustment of the fixed angle of the brush plate at the front end of the brush rod;

[0009] Among them, the adjusting structure includes a groove and a convex edge. Among the two components of the connecting head and the brush plate, the groove is arranged on one of the components, and the convex edge is correspondingly arranged on the other component. Through the fitting between different convex edges and grooves, the brush plate can be rotated and adjusted relative to the brush rod and positioned.

[0010] Through the above technical solution, when the window cleaner with a rotatable head is in normal use, the groove in the adjusting structure is arranged on one of the brush plate or the connecting head, and a matching convex edge is arranged on the other component. The user holds the brush rod for cleaning, inserts the brush plate into the window frame for corner cleaning, and the brush plate rotates and adjusts accordingly. Each convex edge corresponds to a specific rotation angle, and different convex edges are accurately inserted into grooves at different positions, so as to realize the flexible rotation and stable positioning of the brush plate among multiple preset angles, thereby improving the cleaning efficiency and making the cleaning effect better.

[0011] Preferably, the joint portion has a connecting portion, and the brush plate is provided with a connecting hole for the connecting portion to be embedded in, and can rotate in the connecting hole, so as to limit the brush rod from being separated from the brush plate.

[0012] Through the above technical solution, when the brush plate and the brush rod are installed, the connecting part can just pass through the connecting hole of the brush plate to be positioned, limiting the separation of the brush plate and the brush rod, so that the connection constitutes a rotational relationship that can be flexibly rotated, and the connection serves as the rotation axis to realize smooth rotation adjustment of the brush plate relative to the brush rod.

[0013] Preferably, the joint portion is protrudingly formed with a mounting portion, which is arranged along the edge of the joint portion, and the mounting portion is surrounded to form a mounting cavity;

[0014] The brush plate has a protruding portion embedded in the installation cavity and can rotate in the installation cavity. The adjustment structure is correspondingly arranged between the inner wall of the installation cavity and the outer wall of the protruding portion.

[0015] Through the above technical scheme, based on the matching of the shape of the mounting cavity surrounded by the mounting part and the raised part, the raised part is firmly embedded in the mounting cavity to form a tight embedded structure, so that the adjustment structure is built into the inner wall of the mounting cavity and the outer wall of the raised part, effectively preventing the intrusion of impurities such as dust, and at the same time strengthening the rotational connection relationship through embedding, thereby improving the structural strength and stability of use.

[0016] Preferably, the connecting portion is provided with a fastening hole, a fastener is connected in the fastening hole, and the protrusion is fixed in the installation cavity through the fastener;

[0017] The fastener has a limiting portion, which is arranged at the end of the fastener. The connecting portion is sleeved with an elastic member, one end of which abuts against the inner wall of the protruding portion, and the other end abuts against the limiting portion. The elastic force has a tendency to press the protruding portion tightly to fit into the installation cavity.

[0018] Through the above technical solution, the brush plate is opened and the fastener is connected to the fastening hole. The cross-sectional size of the limiting part at the end of the fastener is larger than the channel cross-sectional size of the connecting hole, so that the limiting protrusion is separated from the installation cavity, forming a reliable connection basis and improving stability.

[0019] An elastic member is also sleeved on the connecting portion, and the two ends of the elastic member respectively apply elastic force between the inner wall of the protrusion and the abutting portion, so that the protrusion is always subjected to an elastic force pressed against the bottom of the installation cavity. This trend enhances the stability of the connection and reduces looseness and shaking during use. When the brush plate rotates, the elastic member will be compressed after being subjected to force, so it is also easy for the convex edge to disengage from the groove, and the protrusion can rotate relatively in the installation cavity, further improving the stability of the rotation adjustment.

[0020] Preferably, the number of the convex edges is less than or equal to the number of the concave grooves.

[0021] Through the above technical solution, the number of convex edges is designed to be less than or equal to the number of grooves. At least one convex edge can achieve switching and fitting in multiple corresponding grooves. By increasing the number of convex edges, the maximum number of convex edges is the same as the number of grooves, ensuring that each convex edge can be embedded into the corresponding groove, making the adjustment more stable, avoiding unnecessary convex edges from touching the bottom of the installation cavity, and thus achieving precise adjustment and positioning of the brush plate.

[0022] Preferably, the brush plate is provided with an annular groove, which is arranged around the periphery of the bottom of the convex part for one end of the joint corresponding to the orifice of the installation cavity to be embedded.

[0023] Through the above technical solution, the annular groove is skillfully arranged around the periphery of the bottom of the convex part. Its main function is to provide an accurate embedding space for one end of the joint corresponding to the orifice of the installation cavity to be accurately and firmly embedded therein, so as to provide a space for yielding and strengthen the connection relationship.

[0024] Preferably, the groove is set as a long strip-shaped groove. A plurality of grooves are distributed around the rotation axis of the joint and the convex part. At least two groups of convex edges are distributed, and the two groups of convex edges are arranged perpendicular to each other and embedded into the corresponding grooves.

[0025] Through the above technical solution, the groove is optimized to be a long strip-shaped groove, providing a larger embedding space and adjustment range for the convex edge. At least two groups of convex edges are circumferentially distributed and cooperate with each other. After the convex edges arranged perpendicular to each other are embedded into the grooves, a more stable support structure can be formed, enhancing the stability of the adjustment to maintain a stable cleaning effect.

[0026] Preferably, the shape of the convex part is cylindrical, and the installation cavity is adapted to the convex part.

[0027] Through the above technical solution, the design of the cylindrical convex part is used to achieve smooth rotation adjustment and improve the smoothness of rotation after connection between the two.

[0028] The prominent and beneficial technical effects of this technical solution compared with the prior art are:

[0029] 1. In this technical solution, grooves or convex edges are respectively arranged between the joint and the brush plate. When the convex part rotates in the installation cavity, each convex edge corresponds to a specific rotation angle, and different convex edges are accurately embedded into grooves at different positions, realizing flexible rotation and stable positioning between multiple preset angles of the brush plate, thereby improving the cleaning efficiency and making the cleaning effect better;

[0030] 2. This technical solution provides an elastic member on the connecting portion, and the elastic force acts between the inner wall of the raised portion and the abutting portion, so that the raised portion is always subjected to a force pressing against the bottom of the installation cavity, thereby enhancing the stability of the connection. When the brush plate rotates, the elastic member will be compressed after being subjected to the force, causing the convex edge to disengage from the groove and causing the raised portion to rotate relatively in the installation cavity, thereby further improving the stability of the rotation adjustment.

DETAILED DESCRIPTION

[0036] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0037] Example:

[0038] See also Figure 1 A window cleaner with a rotatable head comprises a brush rod 1 in the shape of a rod body. The brush rod 1 is rotatably connected with a brush plate 4, which is arranged at the end of the brush rod 1. The brush plate 4 is provided with a brush cloth 14, which is arranged on the side of the brush plate 4 away from the connection with the brush rod 1. The brush cloth 14 is connected to the brush plate 4 through a clamping structure and can be replaced for cleaning. The adaptive rotation of the brush plate 4 can conveniently clean the corners of the window frame.

[0039] See also Figure 3 and Figure 4 The brush rod 1 has a joint portion 2, which is arranged at one end of the brush rod 1 close to the brush plate 4. The joint portion 2 is protruded with a mounting portion 15, which is arranged along the edge of the joint portion 2. The mounting portion 15 is surrounded by a mounting cavity 3, and its cavity opening is arranged toward the brush plate 4. The joint portion 2 is provided with a protruding portion 5, which is cylindrical in shape and has a size matching the mounting cavity 3. The protruding portion 5 is correspondingly embedded in the mounting cavity 3 and can rotate in the mounting cavity 3.

[0040] The brush plate 4 is provided with an annular groove 12 which is arranged around the periphery of the bottom of the protruding portion 5 and is used for one end of the joint portion 2 corresponding to the cavity opening of the installation cavity 3 to be embedded.

[0041] The specific rotational connection method between the brush plate 4 and the brush rod 1 can be that a connecting hole 8 is opened on the top of the protruding portion 5, and a connecting portion 7 embedded in the connecting hole 8 is correspondingly provided at the bottom of the mounting cavity 3, and a fastening hole 9 is opened on the end face of the connecting portion 7 facing away from the bottom of the cavity. A fastener 10 is provided in the fastening hole 9. The fastener 10 is preferably a fastening screw. The fastener 10 is threadedly connected in the fastening hole 9, and a limiting portion 13 is provided at its end. The cross-sectional size of the limiting portion 13 is larger than the channel cross-sectional size of the connecting hole 8. Axial positioning is achieved by the cooperation of the connecting portion 7 and the fastener 10. The limiting portion 13 serves to limit the protruding portion 5 from detaching from the mounting cavity 3.

[0042] The connecting portion 7 is sleeved with an elastic member 11, which is preferably a return spring. One end of the elastic member 11 abuts against the inner wall of the protrusion 5, and the other end correspondingly abuts against the limiting portion 13. Its elastic force presses the protrusion 5 tightly and makes it tend to be embedded in the installation cavity 3, thereby improving the rotation stability.

[0043] See also Figure 2 and Figure 3 The brush rod 1 and the brush plate 4 are provided with an adjustment structure 6, and the adjustment structure 6 is correspondingly arranged between the inner wall of the mounting cavity 3 and the outer wall of the raised portion 5 to realize the adjustment of the fixed angle of the brush plate 4 at the front end of the brush rod 1 to achieve the purpose of step-by-step positioning. The adjustment structure 6 includes a groove 61 and a convex edge 62. Among the two components of the joint part 2 and the raised portion 5, the groove 61 is arranged on one of the components, and the convex edge 62 is correspondingly arranged on the other component. This embodiment shows the situation where the convex strip is arranged on the bottom of the mounting cavity 3 and the groove 61 is arranged on the corresponding side end surface of the raised portion 5. Alternatively, the groove 61 can also be arranged on the bottom of the mounting cavity 3, and the convex strip is arranged on the corresponding side end surface of the raised portion 5.

[0044] The number of convex edges 62 is less than or equal to that of the grooves 61. In this embodiment, four convex edges 62 are shown. The convex edges 62 are strip-shaped protrusions. The four convex edges 62 are evenly spaced around the rotation axis of the connecting head 2 and the protruding part 5 and are distributed in at least two groups. The two groups of convex edges 62 are perpendicularly arranged in a "cross" shape. In this embodiment, eight grooves 61 are shown. Each groove 61 is a long strip-shaped groove, which is adapted to the convex edge 62. The eight grooves 61 are evenly spaced around the rotation axis of the connecting head 2 and the protruding part 5. The eight grooves 61 cooperate to form multiple "cross"-shaped structures, which can allow the four convex edges 62 to be inserted into the corresponding grooves 61 at different angles. Alternatively, the grooves 61 can be provided on the side wall of the protruding part 5, and the convex edges 62 can be protruded on the corresponding inner side wall of the installation cavity 3. Or, the grooves 61 are provided on the top end face of the protruding part 5 and extend to the side wall, and the convex edges 62 are protruded on the bottom of the installation cavity 3 and extend to the inner side wall of the installation cavity 3.

[0045] The specific working process of this solution is as follows:

[0046] In this technical solution, the protruding part 5 is embedded in the installation cavity 3, and the fastener 10 is connected to the connecting part 7 to form a rotatable relationship that can rotate flexibly. The connection part serves as the rotation axis to realize the smooth rotation adjustment of the brush plate 4 relative to the brush rod 1. The groove 61 in the adjustment structure 6 is provided on the protruding part 5, and the matching convex edge 62 is provided on the bottom of the installation cavity 3. The user holds the brush rod 1 for cleaning and inserts the brush plate 4 into the window frame for corner cleaning. The brush plate 4 rotates and adjusts accordingly. Each convex edge 62 corresponds to a specific rotation angle, and different convex edges 62 are accurately inserted into the grooves 61 at different positions, so as to realize the flexible rotation and stable positioning of the brush plate 4 among multiple preset angles, thereby improving the cleaning efficiency and making the cleaning effect better.
