Description

Technical Field

[0001] This utility model relates to the field of home furnishing accessories technology, and in particular to a steering adjustment mechanism for a floor scrubber scraper. Background Technology

[0002] The squeegee is a crucial component of a floor scrubber, typically consisting of a squeegee frame, inner clamping strip, squeegee blade, and adjustment mechanisms. The squeegee blade is the part that directly contacts the floor or the roller brush; it is usually made of polyurethane or rubber, offering good elasticity and wear resistance. Based on design, it can be categorized as fixed or floating. Its main functions are squeegeeing and draining water, assisting in cleaning, and preventing debris from tangling with the roller brush. It squeegees wastewater towards the suction port or wastewater tank, working in conjunction with the roller brush to remove stubborn stains and keeping the roller brush clean, ensuring the floor scrubber's cleaning effectiveness and normal operation.

[0003] For example, patent publication number CN221750314U, entitled "Squeegee Assembly for a Floor Scrubber and a Floor Scrubber," includes a squeegee frame, an inner clamping strip, a squeegee blade, and an adjusting component. The squeegee frame includes an arc-shaped squeegee frame body and a snap-fit ​​portion protruding from the arc-shaped inner side of the squeegee frame body. The inner clamping strip is provided with a snap-fit ​​groove, in which the snap-fit ​​portion snaps into the snap-fit ​​groove. The end of the inner clamping strip is also provided with an adjusting portion protruding from the arc-shaped inner side of the squeegee frame. The squeegee blade is clamped between the inner clamping strip and the squeegee frame.

[0004] However, the squeegees on current floor scrubbers only have basic directional adjustment capabilities, and their ability to adjust the cleaning range is significantly limited. For example, when cleaning a large living room, because the cleaning range of the squeegee cannot be expanded, the floor scrubber needs to move back and forth repeatedly to complete the cleaning, which is time-consuming and laborious. When cleaning narrow passageways or under furniture, the cleaning range cannot be narrowed, making it easy to bump into surrounding items and miss some corners, which greatly reduces the cleaning efficiency of the floor scrubber and seriously affects the user experience. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art. When cleaning a large living room, the cleaning range of the squeegee cannot be expanded, so the floor scrubber needs to move back and forth repeatedly to complete the cleaning, which is time-consuming and laborious. When cleaning narrow passages or under furniture, the cleaning range cannot be reduced, which can easily cause collisions with surrounding items and miss some corners, resulting in a significant reduction in the cleaning efficiency of the floor scrubber and seriously affecting the user experience. Therefore, this utility model proposes a squeegee steering adjustment mechanism for floor scrubbers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steering adjustment mechanism for a floor scrubber scraper, comprising an arc-shaped plate and a main scraper, wherein secondary scrapers are respectively provided on both sides of the main scraper, and roller brushes are provided at the bottom ends of both the main scraper and the secondary scrapers. A rotating shaft is provided above the top of each of the two secondary scrapers, and a sliding plate is connected to the top of the rotating shaft. An arc-shaped groove is formed inside the arc-shaped plate, and the outer side wall of the rotating shaft is slidably connected to the inner side wall of the arc-shaped groove. The arc-shaped plate is fixedly installed at the bottom of the floor scrubber, and the sliding plate is slidably connected to the surface of the arc-shaped plate. A limit ring is rotatably connected to the outer side wall of the rotating shaft, and a support shaft is fixedly connected to the outer side wall of the limit ring. The support shaft is fixedly connected to the upper surface of the secondary scrapers.

[0007] Preferably, an arc-shaped rack is fixedly connected to the inner wall of the arc-shaped plate, and a gear is fixedly connected to the outer wall of the rotating shaft, with the gear meshing with the arc-shaped rack.

[0008] Preferably, a baffle is fixedly connected to the inner wall of the arc-shaped plate, and the upper surface of the baffle is slidably connected to the lower surface of the gear.

[0009] Preferably, the two inner sidewalls of the main scraper are provided with slots, and the two outer sidewalls of the sub-scraper are fixedly connected with strips, and the slots and strips are slidably connected.

[0010] Preferably, an elastic sheet is fixedly connected to the bottom end of the rotating shaft, and a vibration column is fixedly connected to the upper surface of the scraper.

[0011] Preferably, the outer side wall of the rotating shaft is provided with a circular groove, and the inner side wall of the limiting ring is fixedly connected with a circular retaining ring.

[0012] Preferably, the elastic sheet is an arched structure with a hollow interior, and the outer surface of the elastic sheet deforms due to mutual pressure with the vibrating column. The circular retaining ring is slidably connected to the inner wall of the circular groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this invention, the effective length of the squeegee can be changed by controlling the relative position of the two sub-squeegees to the main squeegee, thereby controlling the overlap length between the sub-squeegees and the main squeegee. When turning is required, the two sub-squeegees rotate in the same direction, pushing and pulling the main squeegee to achieve turning while maintaining the total length. To adjust the cleaning range, the two sub-squeegees are moved towards each other; moving them closer reduces the cleaning range, while moving them further apart increases the range. This greatly improves the cleaning adaptability of the floor scrubber in different scenarios and meets the usage needs of the floor scrubber in multiple scenarios.

[0015] 2. In this utility model, when adjusting the direction of the scraper, the meshing of the arc-shaped rack and gear drives the rotating shaft to rotate, causing the elastic sheet to periodically press the vibrating column, which causes the surface of the scraper to vibrate, shaking off the attached impurities, thus achieving self-cleaning of the scraper and reducing the frequency of manual cleaning and maintenance.

[0016] 3. In this utility model, the circular groove on the rotating shaft and the circular retaining ring on the limiting ring mutually limit each other, preventing the rotating shaft from shifting up and down and ensuring its stable connection with the dividing scraper; the retaining groove on the inner side wall of the main scraper and the retaining strip on the outer side wall of the dividing scraper are slidably connected to prevent the dividing scraper from detaching from the main scraper, thereby improving the stability of the entire equipment operation and extending the service life of the equipment.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1-5 As shown, this utility model provides a steering adjustment mechanism for a floor scrubber scraper, including an arc-shaped plate 1 and a main scraper 3. Sub-scrapers 4 are respectively arranged on both sides of the main scraper 3. Roller brushes are provided at the bottom ends of both the main scraper 3 and the sub-scrapers 4. A rotating shaft 6 is provided above the top of each of the two sub-scrapers 4. A sliding plate 5 is connected to the top of the rotating shaft 6. An arc-shaped groove 2 is formed inside the arc-shaped plate 1. The outer wall of the rotating shaft 6 is slidably connected to the inner wall of the arc-shaped groove 2. The arc-shaped plate 1 is fixedly installed at the bottom of the floor scrubber. The sliding plate 5 is slidably connected to the surface of the arc-shaped plate 1. A limiting ring 15 is rotatably connected to the outer wall of the rotating shaft 6. A support shaft 7 is fixedly connected to the outer wall of the limiting ring 15. The support shaft 7 is fixedly connected to the upper surface of the sub-scrapers 4.

[0026] The specific settings and functions of this embodiment will be described in detail below. The scraper consists of three parts, with two sub-scraper blades 4 connected by a main scraper blade 3. The effective length of the entire scraper blade is controlled by adjusting the overlap length between the sub-scraper blades 4 and the main scraper blade 3. When the entire scraper blade needs to be steered, both sub-scraper blades 4 are simultaneously rotated to the same side. One sub-scraper blade 4 pushes the main scraper blade 3, while the other sub-scraper blade 4 pulls the main scraper blade 3. This ensures that the total length between the two sub-scraper blades 4 and the main scraper blade 3 remains unchanged, but instead moves the position of the main scraper blade 3, thus achieving the desired scraper blade position. The adjustment function allows for the adjustment of the overall cleaning range of the scraper by moving the two sub-scrapers 4 towards each other. When the two sub-scrapers 4 approach each other, their inner ends retract into the main scraper 3, thus reducing the overall cleaning range. Conversely, when the two sub-scrapers 4 move away from each other, their inner ends protrude from the main scraper 3, thus increasing the overall cleaning range. By controlling the movement of the two sub-scrapers 4, not only is the scraper's direction adjustment function achieved, but also the scraper's cleaning range is adjustable.

[0027] Example 2: Figure 3 , Figure 4 and Figure 5As shown, an arc-shaped rack 10 is fixedly connected to the inner wall of the arc-shaped plate 1, and a gear 8 is fixedly connected to the outer wall of the rotating shaft 6. The gear 8 and the arc-shaped rack 10 mesh with each other. A baffle 9 is fixedly connected to the inner wall of the arc-shaped plate 1, and the upper surface of the baffle 9 is slidably connected to the lower surface of the gear 8. The two inner walls of the main scraper 3 are provided with slots 11, and the two outer walls of the dividing scraper 4 are fixedly connected with clips 12. The slots 11 and clips 12 are slidably connected. An elastic plate 14 is fixedly connected to the bottom end of the rotating shaft 6, and a vibration column 13 is fixedly connected to the upper surface of the dividing scraper 4. A circular groove 16 is provided on the outer wall of the rotating shaft 6, and a circular retaining ring 17 is fixedly connected to the inner wall of the limiting ring 15. The elastic plate 14 is an internally hollow arched structure. The outer surface of the elastic plate 14 is deformed by mutual pressure with the vibration column 13, and the circular retaining ring 17 is slidably connected to the inner wall of the circular groove 16.

[0028] The overall effect of this embodiment is as follows: To control the movement of the scraper 4, a rotating shaft 6 is provided at the upper end of the scraper 4. The top of the rotating shaft 6 is connected to a sliding plate 5, which is made of magnetic material. The sliding plate 5 is controlled to slide on the surface of the arc-shaped plate 1 by magnetic attraction, thereby controlling the movement of the two scraper 4. An arc-shaped rack 10 is installed on the inner wall of the arc-shaped plate 1, and a gear 8 is installed on the outer wall of the rotating shaft 6 to cooperate with it. During the movement of the rotating shaft 6, the gear 8 is rotated by the meshing effect of the arc-shaped rack 10, causing the gear 8 to drive the rotating shaft 6 to rotate spontaneously. The elastic plate 14 at the bottom of the rotating shaft 6 will rotate continuously. Every time the elastic plate 14 rotates, it will approach the vibrating column 13 and be compressed twice. After the elastic plate 14 is compressed by the vibrating column 13, it will deform. The elasticity caused by the deformation of the elastic plate 14 will cause vibration. This causes the scraper 4 to vibrate and shake off impurities adhering to its surface during subsequent rotation, thus providing a cleaning effect while adjusting the scraper's direction. Additionally, a circular groove 16 is formed on the surface of the rotating shaft 6, and a circular retaining ring 17 is provided on the inner wall of the limiting ring 15, allowing the circular groove 16 and the circular retaining ring 17 to mutually limit each other, preventing the rotating shaft 6 from shifting vertically and ensuring the connection between the rotating shaft 6 and the lower scraper 4. To further improve the structural connection stability of the main scraper 3 and the scraper 4, a slot 11 is formed on the inner wall of the main scraper 3, and matching retaining strips 12 are installed on both sides of the scraper 4, allowing the main scraper 3 and the scraper 4 to slide within a plane, preventing the scraper 4 from detaching from the main scraper 3 and improving the overall stability of the equipment operation.

[0029] The usage and working principle of this device are as follows: When steering adjustment is required, the magnetic sliding plate 5 is controlled to slide on the surface of the arc plate 1 by magnetic attraction, which drives the rotation shaft 6 at the upper end of the scraper 4 to move, controlling the two scrapers 4 to rotate to the same side. One pushes and the other pulls the main scraper 3, so that its position moves to achieve the direction of the scraper, while the total length remains unchanged.

[0030] When the cleaning range needs to be adjusted, the two scraper blades 4 are moved towards each other. When the two scraper blades 4 are close together, the cleaning range decreases, and when the two scraper blades 4 are far apart, the cleaning range increases. The groove 11 on the inner side wall of the main scraper blade 3 is slidably connected to the strip 12 on the outer side wall of the scraper blade 4, which improves the stability of the structural connection.

[0031] Meanwhile, the gear 8 on the rotating shaft 6 meshes with the arc-shaped rack 10 on the inner side wall of the arc plate 1, causing the rotating shaft 6 to rotate spontaneously. The elastic plate 14 at its bottom rotates accordingly. Every time it rotates once, it presses against the vibrating column 13 on the scraper 4 twice. The deformation of the elastic plate 14 causes vibration to strike the vibrating column 13, which in turn causes the surface of the scraper 4 to vibrate and clean impurities. The circular groove 16 on the rotating shaft 6 and the circular retaining ring 17 on the limiting ring 15 mutually limit each other, improving the stability of the structural connection.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
