Description
Technical Field
[0001] This utility model relates to the field of floor scrubber technology, and in particular to a vertical adjustment mechanism for the scraper of a floor scrubber. Background Technology
[0002] A floor scrubber is a cleaning device primarily used for cleaning floors, capable of simultaneously cleaning the floor and recovering wastewater. The scrubber is driven by a motor to rotate a brush disc, which is typically located at the bottom of the machine. The brush bristles contact the floor, effectively removing dust, stains, oil, and other grime as it rotates. Additionally, the scrubber is equipped with a clean water tank; during cleaning, clean water is sprayed onto the floor, helping to dissolve stains and reducing friction between the brush disc and the floor.
[0003] The squeegee (scraper) located behind the brush plate fits tightly against the ground. It scrapes the wastewater generated after the brush plate cleans the ground together, and then the water suction motor sucks the wastewater into the wastewater tank, so that the ground can dry quickly after cleaning, reduce water stains and avoid safety hazards such as pedestrians slipping.
[0004] However, existing technologies present a series of problems when floor scrubbers operate on uneven surfaces. Firstly, if the surface is concave, the wear between the scrubber blade and the surface will significantly increase. Secondly, if the surface is convex, the gap between the scrubber blade and the surface will widen, making wastewater collection more difficult. Currently available floor scrubber blades lack an effective vertical adjustment mechanism, making it difficult to solve these problems. Utility Model Content
[0005] The purpose of this invention is to address the problems in the existing technology where, on the one hand, if the ground is sunken, the wear between the scrubbing machine blade and the ground will be significantly aggravated; on the other hand, if the ground is convex, the gap between the scrubbing machine blade and the ground will increase, making it more difficult to recycle wastewater. Therefore, this invention proposes a vertical adjustment mechanism for the scrubbing machine blade.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vertical adjustment mechanism for a floor scrubber scraper, comprising a scraper connecting plate and a scraper connecting frame, wherein the scraper connecting frame is installed on the main body of the floor scrubber, a second locking block is fixedly connected to the inner bottom wall of the scraper connecting frame, a first locking block is fixedly connected to the inner top wall of the scraper connecting frame, guide blocks are fixedly connected to the top and bottom surfaces of the scraper connecting plate, an elongated groove is provided on the inner side wall of the scraper connecting plate, a positioning pin is fixedly connected inside the scraper connecting frame, the positioning pin is slidably connected to the scraper connecting plate through the elongated groove, and a scraper body is fixedly connected to one end of the scraper connecting plate.
[0007] Preferably, tension springs are connected to both sides of the scraper connecting frame, and one end of the tension spring is connected to the scraper connecting plate.
[0008] Preferably, an electromagnet is fixedly connected to the inner side wall of the scraper connecting frame, and a magnetic plate is fixedly connected to one end of the scraper connecting plate.
[0009] Preferably, a filter screen is installed inside the wastewater recovery port.
[0010] Preferably, the inclined surfaces of the first card block, the guide block, and the second card block are all polished.
[0011] Preferably, the top of the scraper body is connected to a sewage recovery port, and a roller is installed on one side of the scraper body.
[0012] Preferably, the bottom end of the scraper body is provided with an arc-shaped groove.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, an electromagnet is installed on the inner wall of the scraper connecting frame. The horizontal position of the scraper connecting plate is controlled by controlling the magnetic repulsion between the electromagnet and the magnetic plate at one end of the scraper connecting plate. The scraper connecting plate and the scraper connecting frame are limited in the height direction by a locking block one, a guide block and a locking block two, respectively, thereby driving the scraper body to move up and down. When the ground is uneven, the distance between the scraper body and the ground can be adjusted by adjusting the scraper connecting plate. When the distance between the scraper and the ground is close, the distance between them can be appropriately increased to reduce the wear of the scraper on the ground. When the distance between the scraper and the ground is far, the distance between them can be appropriately decreased to improve the sewage collection effect. This not only effectively extends the service life of the floor scrubber parts, but also improves the cleaning effect on the ground.
[0015] 2. In this utility model, by designing the scraper body as an arc-shaped structure, the wastewater from the floor scrubber can be effectively collected in the middle. The wastewater is then connected to the wastewater collection port of the floor scrubber's wastewater tank at the top of the scraper body, achieving centralized wastewater treatment and improving wastewater recovery efficiency and cleaning effect. Simultaneously, by setting elongated grooves, positioning pins, guide blocks, and locking blocks one and two on the scraper connecting plate, the distance between the scraper body and the ground can be vertically adjusted according to the flatness of the ground. When the scraper connecting plate retracts towards the scraper connecting frame, the scraper body moves closer to the ground, fully recovering the wastewater remaining on the ground and ensuring a clean cleaning effect.

[0022] 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.
[0023] 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.
[0024] Example 1: As Figure 1-5 As shown, this utility model provides a vertical adjustment mechanism for a floor scrubber scraper, including a scraper connecting plate 1 and a scraper connecting frame 2. The scraper connecting frame 2 is installed on the main body of the floor scrubber. A second locking block 7 is fixedly connected to the inner bottom wall of the scraper connecting frame 2, and a first locking block 5 is fixedly connected to the inner top wall of the scraper connecting frame 2. Guide blocks 6 are fixedly connected to the top and bottom surfaces of the scraper connecting plate 1. An elongated groove 9 is provided on the inner side wall of the scraper connecting plate 1. A positioning pin 3 is fixedly connected inside the scraper connecting frame 2. The positioning pin 3 is slidably connected to the scraper connecting plate 1 through the elongated groove 9. A scraper body 11 is fixedly connected to one end of the scraper connecting plate 1.
[0025] The specific settings and functions of this embodiment are described below. The floor scrubber squeegee is located behind the scrubber brush and is used to collect wastewater from the floor after scrubbing. The squeegee body 11 is connected to the floor scrubber body via a squeegee connecting plate 1. One end of the squeegee connecting plate 1 is mounted on the floor scrubber via a squeegee connecting bracket 2, and the other end of the squeegee connecting plate 1 is fitted with the squeegee body 11. The squeegee body 11 is designed with an arc-shaped structure, which effectively collects wastewater in the middle for better centralized collection. When the ground is uneven, the distance between the squeegee body 11 and the ground changes. If the distance between the squeegee body 11 and the ground is too close, then... This can cause unnecessary wear on the bottom of the scraper body 11, easily damaging parts. If the scraper body 11 is too far from the ground, it cannot fully absorb the sewage below, resulting in the scraper not achieving the desired cleaning effect. A long groove 9 is made on the surface of the scraper connecting plate 1, and a positioning pin 3 is inserted into the groove 9 for positioning, allowing the scraper connecting plate 1 to extend outwards or retract towards the detergent body. Simultaneously, guide blocks 6 are installed above and below the scraper connecting plate 1. One guide block 6 slides with the upper locking block 5, and the other guide block 6 slides with the lower locking block 7. (Refer to the attached document.) Figure 2 The description explains that when the scraper connecting plate 1 retracts towards the scraper connecting frame 2, the first locking block 5 and the guide block 6 limit the height position of the scraper connecting plate 1. The inclined surface of the first locking block 5 pushes the guide block 6 downward, causing the guide block 6 to move the scraper connecting plate 1 downward. At this time, the height position of the scraper connecting plate 1 will decrease, causing the scraper connecting plate 1 to move the scraper body 11 closer to the ground, completing the vertical adjustment of reducing the distance between the scraper body 11 and the ground, which facilitates the full recovery of sewage remaining on the ground. When the scraper connecting plate 1 moves outward, the guide block 6 and the second locking block 7 limit the height position of the scraper connecting plate 1. The inclined surface of the second locking block 7 pushes the guide block 6 upward, causing the guide block 6 to move the scraper connecting plate 1 upward. At this time, the position of the scraper connecting plate 1 will rise, causing the scraper connecting plate 1 to move the scraper body 11 away from the ground, realizing the vertical adjustment of increasing the distance between the scraper body 11 and the ground, reducing the wear of the ground on the scraper, and effectively extending the service life of the floor scrubber parts.
[0026] Example 2: Figure 3 and Figure 4 As shown, tension springs 4 are connected to both sides of the scraper connecting frame 2, and one end of the tension spring 4 is connected to the scraper connecting plate 1. An electromagnet 8 is fixedly connected to the inner side wall of the scraper connecting frame 2, and a magnetic plate 13 is fixedly connected to one end of the scraper connecting plate 1. An arc-shaped groove is opened at the bottom end of the scraper body 11. The inclined surfaces of the first locking block 5, the guide block 6, and the second locking block 7 are all polished. The top of the scraper body 11 is connected to a sewage recovery port 12, a roller 10 is installed on one side of the scraper body 11, and a filter screen is installed inside the sewage recovery port 12.
[0027] The overall effect of this embodiment is as follows: To control the horizontal position of the scraper connecting plate 1, an electromagnet 8 is installed on the inner wall of the scraper connecting frame 2. The electromagnet 8 is connected to the internal circuit system of the floor scrubber, and its magnetic field can be controlled. In addition, a magnetic plate 13 is installed at one end of the scraper connecting plate 1. A magnetic repulsion force is generated between the magnetic plate 13 and the electromagnet 8. When the electromagnet 8 is connected to the power supply, the magnetic repulsion force of the electromagnet 8 on the magnetic plate 13 causes the scraper connecting plate 1 to move outward. With the cooperation of the guide block 6 and the second locking block 7, the scraper connecting plate 1 and the scraper body 11 are lifted upward. When the electromagnet 8 is connected to the power supply... When disconnected, the electromagnet 8 no longer generates magnetic repulsion on the magnetic plate 13. At this time, the tension of the tension spring 4 pulls the scraper connecting plate 1 into the scraper connecting frame 2. With the cooperation of the locking block 5 and the guide block 6, the scraper connecting plate 1 and the scraper body 11 move downward. Rollers 10 are also installed on both sides of the scraper body 11 to provide some support for the scraper body 11 and reduce the friction generated by the scraper body 11 moving on the ground. The top of the scraper body 11 is connected to the sewage recovery port 12. One end of the sewage recovery port 12 is connected to the sewage tank of the floor scrubber to collect and treat the sewage after the floor is washed.
[0028] The operating method and working principle of this device are as follows: The squeegee of the floor scrubber is located behind the brush plate. The squeegee body 11 is connected to the floor scrubber body via the squeegee connecting plate 1. One end of the squeegee connecting plate 1 is installed on the floor scrubber via the squeegee connecting frame 2, and the other end is fitted with the squeegee body 11. The squeegee body 11 is designed with an arc-shaped structure, which can effectively collect the wastewater from the floor after the floor scrubber has treated it in the middle position. Then, the wastewater is introduced into the wastewater tank of the floor scrubber for centralized treatment through the wastewater collection port 12 connected above the squeegee body 11. The electromagnet 8 is connected to the internal circuit system of the floor scrubber and can control the on and off of the magnetic field. A magnetic plate 13 is installed at one end of the squeegee connecting plate 1, and a magnetic repulsion force is generated between the magnetic plate 13 and the electromagnet 8.
[0029] A long groove 9 is made on the surface of the scraper connecting plate 1, and a positioning pin 3 is inserted for positioning, so that the scraper connecting plate 1 can extend outward or retract towards the body of the floor scrubber. Guide blocks 6 are installed on both the top and bottom of the scraper connecting plate 1. One side of the guide block 6 is slidably engaged with the upper locking block 5, and the other side of the guide block 6 is slidably engaged with the lower locking block 7.
[0030] When the electromagnet 8 is disconnected from the power supply, the electromagnet 8 no longer generates magnetic repulsion on the magnetic plate 13. The tension of the tension spring 4 pulls the scraper connecting plate 1 into the scraper connecting frame 2. The locking block 5 and the guide block 6 limit its height position. The inclined surface of the locking block 5 pushes the guide block 6 downward. The guide block 6 drives the scraper connecting plate 1 to move downward, so that the scraper connecting plate 1 drives the scraper body 11 closer to the ground, reducing the distance between the scraper body 11 and the ground, which facilitates the full recycling of sewage.
[0031] When the electromagnet 8 is connected to the power supply, the magnetic repulsion of the electromagnet 8 on the magnetic plate 13 causes the scraper connecting plate 1 to move outward. The guide block 6 and the second locking block 7 limit its height position. The inclined surface of the second locking block 7 pushes the guide block 6 upward. The guide block 6 drives the scraper connecting plate 1 to move upward, so that the scraper connecting plate 1 drives the scraper body 11 away from the ground, increasing the distance between the scraper body 11 and the ground, reducing the wear of the ground on the scraper, and extending the service life of the parts.
[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.
