Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning tools, and relates to a scrubbing tool, and more particularly to a multifunctional scrubbing tool. Background Technology

[0002] With advancements in productivity and changes in living environments, the market demand for mops is increasing. Certain specialized cleaning environments require the use of specialized mops. Common types of mops include: telescopic mops with extendable handles, mops with adjustable handle lengths, and mops with adjustable angles between the mop head and handle. There are many other types of these specialized mops.

[0003] However, as hospital support staff used the equipment, they found that cleaning glass doors and window sills was very inconvenient due to the height of the sills. Unless they climbed up to the top of the sills to clean them, they could not get them clean. There were also some exterior walls or glass facades with sills that were difficult to clean due to the angle and obstructions. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a multifunctional cleaning tool. It solves the technical problem of poor adaptability of existing mops during cleaning.

[0005] The objective of this utility model can be achieved through the following technical solutions: A multi-functional cleaning tool includes two hollow straight rods, a first rod and a second rod. The ends of the first rod and the second rod are fixedly connected, and the center lines of the first rod and the second rod are perpendicular to each other. A mop head is rotatably connected to the other end of the first rod, and a handle is rotatably connected to the other end of the second rod. A coupling assembly is provided on the inner side of the first rod and the second rod. The handle and the mop head are connected and linked through the coupling assembly. A limiting structure is provided on the second rod near the handle. The limiting structure is configured to lock the handle to restrict the rotation of the coupling assembly and the mop head.

[0006] The cleaning tool of this application includes a straight rod one and a straight rod two, which are connected vertically. The mop head is connected to the straight rod one, so that the mop head and the straight rod two are at a vertical angle. When the user holds the straight rod two, the mop head can extend laterally, i.e., towards the inside of the eaves, because it is connected to the straight rod one. Or, when the cleaning tool is extended from the window, the mop head on the straight rod one can be held towards the window glass. In this way, the straight rod two can be moved to clean the eaves or window glass, which can conveniently clean places with a certain height.

[0007] The cleaning tool of this application also includes a coupling assembly. The mop head is linked to the handle located on the straight rod two through the coupling assembly. When encountering some corners or special positions, the orientation angle of the mop head can be adjusted according to the situation on site. That is, by turning the handle, the mop head can be adjusted to the appropriate cleaning angle. Then, the handle is locked by a limiting structure to prevent the mop head from rotating due to force during cleaning. The on-site adjustment can flexibly change to adapt to the cleaning environment, allowing users to clean some special positions more easily.

[0008] In the aforementioned multi-functional cleaning tool, the coupling assembly includes connecting rod one, connecting rod two, and a universal joint coupling. The two ends of the universal joint coupling are fixed to connecting rod one and connecting rod two, respectively. Connecting rod one is located inside straight rod one, and connecting rod two is located inside straight rod two. The universal joint coupling is located at the junction where straight rod one and straight rod two are perpendicularly connected, and is used for reversing direction. Connecting rod one is fixed to the end of the mop head, and connecting rod two is fixed to the handle.

[0009] The coupling assembly of this application specifically includes connecting rod one, connecting rod two, and a universal joint coupling. The lengths of connecting rod one and connecting rod two roughly correspond to straight rod one and straight rod two. The universal joint coupling is mainly used to connect connecting rod one and connecting rod two so that they can rotate in conjunction. With this design, when the handle is turned, connecting rod two, universal joint coupling, connecting rod one, and mop head can rotate synchronously in sequence. When the handle is locked, connecting rod one, connecting rod two, and universal joint coupling can also be limited, so that the orientation angle of the mop head can be adjusted and changed according to needs, making it highly adaptable.

[0010] In the aforementioned multifunctional scrubbing tool, the limiting structure includes several limiting grooves circumferentially opened along the side of the handle and a sliding sleeve circumferentially fixed to the two ends of the straight rod. The sliding sleeve is provided with a limiting protrusion protruding towards the handle. The sliding sleeve can slide along the axial direction of the two straight rods so that the limiting protrusion and the limiting groove can be inserted and pulled together. The limiting structure also includes a blocking sleeve threadedly connected to the two straight rods. The blocking sleeve can move towards the sliding sleeve and abut against the sliding sleeve by rotating the thread.

[0011] This limiting structure includes a sliding sleeve and several limiting grooves. The sliding sleeve is fitted onto the second straight rod and is circumferentially fixed to the second straight rod. The sliding sleeve can slide relative to the second straight rod so that the limiting protrusion on it can be inserted into or pulled out of the limiting groove on the handle. After the handle is rotated and the angle is adjusted, the handle is locked by moving the sliding sleeve so that the limiting protrusion on it can be inserted into the limiting groove in the corresponding state. After the sliding sleeve locks the handle, the blocking sleeve is rotated by the thread to abut against the sliding sleeve to limit its axial movement. This design makes it very convenient to adjust the position of the handle and it is stable and reliable after adjustment.

[0012] In the aforementioned multi-functional scrubbing tool, the side of the blocking sleeve has a protruding mounting part, and an auxiliary handle is fixed at the mounting part. The auxiliary handle has a handle part, which is parallel to the straight rod and extends toward the handle direction.

[0013] In addition to preventing the sliding sleeve from sliding axially, the blocking sleeve of this application is also connected to an auxiliary handle. When cleaning, the user can hold the straight rod and the auxiliary handle with both hands to increase the stability during cleaning and prevent problems such as loss of control due to inertia during high-altitude operations.

[0014] In the aforementioned multifunctional cleaning tool, the mop head includes a connector and a mop head, which are fixedly connected. The connector is axially fixed to the end of a connecting rod and can rotate circumferentially relative to the connecting rod. The inner side of the connector has a prismatic inner hole. A prismatic block adapted to the inner hole is fixed on the connecting rod. The prismatic block is located inside the inner hole and is circumferentially fixed to the inner hole. The mop head has a long, strip-shaped rod, which is fixedly connected to the connector.

[0015] The mop head of this application is divided into a connector and a mop head. The connector and the connecting rod are engaged by a prism and a prism-shaped inner hole to achieve the effect of driving the mop head to rotate circumferentially. The mop head is fixedly connected to the connector. By rotating the connector, the position of the mop head can be adjusted to change the orientation angle to adapt to cleaning some corners or special locations.

[0016] In the aforementioned multifunctional scrubbing tool, an annular component is fitted onto the end of the straight rod, and the annular component is threadedly connected and fixed to the straight rod. An annular flange protrudes inward from the end of the annular component, and an annular limiting groove is formed between the annular flange and the end of the straight rod. An annular protrusion protrudes from the outer circumferential surface of the connector and is embedded in the annular limiting groove. The annular protrusion can rotate circumferentially relative to the side wall of the annular limiting groove.

[0017] The straight rod of this application is fitted with an annular component. The annular flange on the annular component and the straight rod form an annular limiting groove that can limit the annular protrusion on the connector, so that the connector can be both fixed to the straight rod and rotate circumferentially. This connection structure is ingenious and highly practical.

[0018] In the aforementioned multi-functional scrubbing tool, an annular groove is provided on the inner side of the end of the second connecting rod, and a clip protrudes from the handle, engaging with the annular groove and capable of moving along the annular groove.

[0019] The second connecting rod of this application is connected to the handle using a quick-release structure with a clip and a ring groove. This design makes the connection convenient and allows for stable rotation of the handle, making it very convenient and practical.

[0020] In the aforementioned multi-functional scrubbing tool, the clips are multiple and have a claw-like structure.

[0021] In the aforementioned multi-functional scrubbing tool, the scrubbing tool also includes a right-angle connector. The two ends of the right-angle connector are respectively connected to the ends of straight rod one and straight rod two, and the right-angle connector is fixedly connected to both straight rod one and straight rod two. The universal joint coupling is located in the internal channel of the right-angle connector.

[0022] In the aforementioned multi-functional scrubbing tool, the length of the second straight rod is much greater than the length of the first straight rod.

[0023] Compared with existing technologies, the advantages of this product are: 1. The cleaning tool of this application includes a straight rod one and a straight rod two, which are connected vertically. The mop head is connected to the straight rod one, so that the mop head and the straight rod two are at a vertical angle. When the user holds the straight rod two, the mop head can extend laterally, that is, to the inside of the eaves, because it is connected to the straight rod one. In this way, the eaves can be cleaned by moving the straight rod two. The length of the straight rod one corresponds to the width of the eaves. By extending the mop head into the inside of the eaves through the straight rod one, it is very convenient to clean the top of the eaves.

[0024] 2. The cleaning tool of this application also includes a coupling assembly. The mop head is linked to the handle located on the straight rod two through the coupling assembly. When the user holds the straight rod two to clean the corner between the eaves and the exterior wall, he / she can control the angle of the mop head by turning the handle to clean the exterior wall. It is very convenient to control and can achieve free switching of cleaning angle. Attached Figure Description

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] Example 1 like Figures 1-4 The multi-functional cleaning tool shown includes a hollow straight rod 1 and a hollow straight rod 2. The ends of straight rod 1 and straight rod 2 are fixedly connected, and the center lines of straight rod 1 and straight rod 2 are perpendicular to each other. A mop head 3 is rotatably connected to the other end of straight rod 1, and a handle 4 is rotatably connected to the other end of straight rod 2. A coupling assembly 5 is provided on the inner side of straight rod 1 and straight rod 2. The handle 4 and the mop head 3 are connected and linked through the coupling assembly 5. A limiting structure 6 is provided on straight rod 2 near the handle 4. The limiting structure 6 is configured to lock the handle 4 to restrict the rotation of the coupling assembly 5 and the mop head 3. Before cleaning, the position of the mop head 3 should be adjusted according to the site conditions, for example... Figure 4As shown, when starting to clean, adjust the mop head 3 to be arranged horizontally in a straight line. This can accommodate cleaning most window glass. When encountering a corner, adjust the mop head 3 to tilt so that one corner of the mop head 3 is angled to better suit the corner cleaning. At the same time, because the mop head 3 is tilted, the user holding the mop from behind does not need to make any special complicated movements to adapt to corner cleaning. Just push and pull the mop normally, which is very convenient. Similarly, when cleaning other special areas, simply adjust the mop head 3 to the optimal position before cleaning, which is also very convenient. The cleaning tool of this application includes a straight rod 1 and a straight rod 2, which are connected vertically. The mop head 3 is connected to the straight rod 1, so that the mop head 3 and the straight rod 2 are at a vertical angle. When the user holds the straight rod 2, the mop head 3 can extend laterally, i.e., towards the inside of the eaves, because it is connected to the straight rod 1. Or, when the cleaning tool is extended from the window, the mop head 3 on the straight rod 1 can be held towards the window glass. In this way, the straight rod 2 can be moved to clean the eaves or window glass, which can conveniently clean places with a certain height. The cleaning tool of this application also includes a coupling assembly 5. The mop head 3 is linked to the handle 4 located on the straight rod 2 via the coupling assembly 5. When encountering corners or special positions, the orientation angle of the mop head 3 can be adjusted according to the situation. That is, by rotating the handle 4, the mop head 3 can be adjusted to a suitable cleaning angle. Then, the handle 4 is locked by the limiting structure 6 to prevent the mop head 3 from rotating due to force during cleaning. This flexible adjustment allows the user to adapt to the cleaning environment and makes it easier to clean some special positions. The angle adjustment of the mop head 3 of this cleaning tool is as follows: First, extend the cleaning tool to the cleaning position for comparison to determine the approximate position where the mop head 3 needs to be adjusted. Then, unlock the limiting structure 6 to make the handle 4 free. Rotate the handle 4 to drive the coupling assembly 5 to rotate, which in turn drives the mop head 3 located at the end to rotate to the appropriate position. Lock the limiting structure 6 to lock the handle 4. Finally, clean. After cleaning special positions, adjust the mop head 3 back to the normal horizontal position.

[0029] The specific structure of the coupling assembly 5 in this embodiment includes connecting rod 1 51, connecting rod 2 52, and universal joint coupling 53. Universal joint coupling 53 is a mature existing technology and will not be elaborated upon here. Both ends of universal joint coupling 53 are fixed to connecting rod 1 51 and connecting rod 2 52 respectively. Connecting rod 1 51 is located inside straight rod 1, and connecting rod 2 52 is located inside straight rod 2. Universal joint coupling 53 is located at the junction where straight rod 1 1 and straight rod 2 2 are perpendicularly connected, and is used for reversing direction. Connecting rod 1 51 is fixed to the end of mop head 3, and connecting rod 2 52 is fixed to handle 4. To increase structural strength, bushings or similar annular limiting seats can be added at the ends of connecting rod 1 51 and connecting rod 2 52, at both ends of straight rod 1 1 and straight rod 2 2. These can circumferentially cooperate with connecting rod 1 51 and connecting rod 2 52 without affecting their rotation, but can provide support and positioning. The coupling assembly 5 of this application specifically includes a connecting rod 51, a connecting rod 52, and a universal joint coupling 53. The lengths of connecting rod 51 and connecting rod 52 roughly correspond to straight rod 1 and straight rod 2. The universal joint coupling 53 is mainly used to connect connecting rod 51 and connecting rod 52 so that they can rotate in conjunction. With this design, when the handle 4 is turned, connecting rod 52, universal joint coupling 53, connecting rod 51, and mop head 3 can rotate synchronously in sequence. When the handle 4 is locked, connecting rod 51, connecting rod 52, and universal joint coupling 53 can also be limited, so that the orientation angle of the mop head 3 can be adjusted and changed according to the needs, making it highly adaptable.

[0030] The specific structure of the limiting structure 6 in this embodiment includes a plurality of limiting grooves 61 circumferentially opened along the side of the handle 4 and a sliding sleeve 62 circumferentially fixed on the end of the straight rod 2. The sliding sleeve 62 is provided with a limiting protrusion 621 protruding toward the handle 4. The sliding sleeve 62 can slide along the axial direction of the straight rod 2 so that the limiting protrusion 621 and the limiting groove 61 can be inserted and pulled together. The limiting structure 6 also includes a blocking sleeve 63 threadedly connected to the straight rod 2. The blocking sleeve 63 can move toward the sliding sleeve 62 and abut against the sliding sleeve 62 by rotating the thread. This limiting structure 6 includes a sliding sleeve 62 and several limiting grooves 61. The sliding sleeve 62 is fitted onto the straight rod 2 and is circumferentially fixed to the straight rod 2. The sliding sleeve 62 can slide relative to the straight rod 2 so that the limiting protrusion 621 on it can be inserted into or pulled out of the limiting groove 61 on the handle 4. After the handle 4 is rotated and the angle is adjusted, the sliding sleeve 62 is moved so that the limiting protrusion 621 on it can be inserted into the limiting groove 61 in the corresponding state to lock the handle 4. After the sliding sleeve 62 locks the handle 4, the blocking sleeve 63 is rotated by the thread to abut against the sliding sleeve 62 to limit its axial movement. This design makes it very convenient to adjust the position of the handle 4 and it is stable and reliable after adjustment. A rib protrudes circumferentially from the end of the straight rod 2, and the ribs are arranged along the length of the straight rod 2. The inner side of the sliding sleeve 62 has a guide portion that mates with the rib. The structure of the rib and the guide portion is not shown in the attached drawing due to the angle, but this is a conventional mechanical structure that serves the function of circumferential fixation and axial sliding, so there is no objection to the overall understanding, and therefore it will not be elaborated further here. The cooperation between the rib and the guide portion allows the sliding sleeve 62 to be circumferentially fixed on the straight rod 2 and to move axially relative to the straight rod 2.

[0031] Preferably, the side of the blocking sleeve 63 has a protruding mounting portion 631, and an auxiliary handle 7 is fixed at the mounting portion 631. The auxiliary handle 7 has a handle portion 71, which is parallel to the straight rod 2 and extends towards the handle 4. In addition to preventing the sliding sleeve 62 from sliding axially, the blocking sleeve 63 of this application also has an auxiliary handle 7 connected to it. When cleaning, the user can hold the straight rod 2 and the auxiliary handle 7 with both hands to increase the stability during cleaning and prevent problems such as loss of control due to inertia during high-altitude operations.

[0032] Furthermore, the mop head 3 includes a connector 31 and a mop head 32, which are fixedly connected. The connector 31 is axially fixed to the end of the connecting rod 51 and can rotate circumferentially relative to the connecting rod 51. The inner side of the connector 31 has a prismatic inner hole 311. A prismatic block 511 adapted to the inner hole 311 is fixed on the connecting rod 51. The prismatic block 511 is located inside the inner hole 311 and is circumferentially fixed to the inner hole 311. The mop head 32 has a long strip-shaped rod 321, which is fixedly connected to the connector 31. The mop head 3 of this application is divided into a connector 31 and a mop head 32. The connector 31 and the connecting rod 51 cooperate through the prism block 511 and the prism-shaped inner hole 311 to achieve the effect of driving the mop head 32 to rotate circumferentially. The mop head 32 is fixedly connected to the connector 31. By rotating the connector 31, the position of the mop head 32 can be adjusted to change the orientation angle to adapt to the cleaning of some corners or special positions.

[0033] Furthermore, an annular component 8 is fitted onto the end of the straight rod 1. The annular component 8 is threadedly connected and fixed to the straight rod 1. An annular flange 81 protrudes inward from the end of the annular component 8, forming an annular limiting groove 82 between the annular flange 81 and the end of the straight rod 1. An annular protrusion 312 protrudes from the outer circumferential surface of the connector 31 and is embedded in the annular limiting groove 82. The annular protrusion 312 can rotate circumferentially relative to the side wall of the annular limiting groove 82. In this application, the straight rod 1 is fitted with an annular component 8, and the annular flange 81 on the annular component 8 and the straight rod 1 form an annular limiting groove 82, which can limit the annular protrusion 312 on the connector 31. This allows the connector 31 to be both fixed to the straight rod 1 and able to rotate circumferentially. This connection structure is ingenious and highly practical. When adjusting the angle of the mop head 3 in actual use, the ring part 8 can be rotated appropriately to loosen it, making the rear handle 4 easier to rotate. After the angle is adjusted properly, tightening the ring part 8 can also play a certain limiting role, and the friction can help the mop head 3 maintain its position better.

[0034] Furthermore, an annular groove 21 is formed on the inner side of the end of the second connecting rod 52, and a latch 41 protrudes from the handle 4, engaging with the annular groove 21 and movable along the annular groove 21. The connecting rod 52 and the handle 4 in this application are connected by a quick-release structure using the latch 41 and the annular groove 21. This design facilitates connection and ensures stable rotation of the handle 4, making it very convenient and practical. Preferably, the latch 41 has multiple latches and a claw-like structure.

[0035] Furthermore, this cleaning tool also includes a right-angle connector 9, with both ends of the right-angle connector 9 respectively connecting to the ends of straight rod 1 and straight rod 2, and the right-angle connector 9 is fixedly connected to both straight rod 1 and straight rod 2. The universal joint coupling 53 is located in the internal channel of the right-angle connector 9.

[0036] Furthermore, the length of straight rod 2 is much greater than the length of straight rod 1.

[0037] Example 2 This embodiment is another implementation of the coupling structure. The other structures are basically the same as those in the embodiment, except that the universal joint coupling 53 in this embodiment can be a flexible connecting part, such as a steel cable, as long as it can play a similar or equivalent coupling role.
