Description

Technical Field

[0001] This utility model relates to a squeegee, and more particularly to a squeegee for a floor scrubber. Background Technology

[0002] A squeegee is a device installed on a floor scrubber. After the floor scrubber finishes scrubbing, the squeegee can remove the water left behind by the scrubber.

[0003] A squeegee typically consists of a squeegee section and a pressure strip. The pressure strip is installed on the front and rear sides of the squeegee section. The lower end of the squeegee section is usually made of a soft material, such as rubber. A water inlet is often provided at the lower end of the squeegee section. When in use, the squeegee section is installed at the rear end of the floor scrubber. After the floor scrubber has finished scrubbing, the lower end of the squeegee section contacts the ground and can suck up the water from the ground.

[0004] Existing squeegees have the following problems: the squeegee is not easy to install, such as the strip not being able to press the lower end of the squeegee tightly, and there is a large gap between the lower end of the squeegee and the ground, resulting in poor water absorption and a lot of residual water on the ground, which affects the floor cleaning effect. Utility Model Content

[0005] The purpose of this utility model is to provide a squeegee for a floor scrubber to solve the technical problems existing in the squeegee of the prior art.

[0006] According to one aspect of the present invention, a squeegee for a floor scrubber is provided, including an arc-shaped squeegee section with a water inlet formed thereon and a suction fan provided thereon. Water from the floor scrubber enters the arc-shaped squeegee section through the water inlet and is sucked out by the suction fan. Pressure strips are provided on the front and rear sides of the arc-shaped squeegee section, and pressure plates are provided at the left and right ends of the arc-shaped squeegee section. The two pressure plates can hold the pressure strips on the front and rear sides.

[0007] In some embodiments, the pressure strip is arc-shaped, and the pressure plate is formed with a receiving groove. One pressure plate is locked at the left end of the arc-shaped wiper part through the receiving groove to lock the left ends of the two pressure plates. The other pressure plate is locked at the right end of the arc-shaped wiper part through the receiving groove to lock the right ends of the two pressure plates.

[0008] In some embodiments, positioning protrusions are formed on both the front and rear sides of the arc-shaped wiper section, and positioning grooves are provided at the corresponding positions of the pressure strips. The positioning grooves can be located at the positioning protrusions.

[0009] In some embodiments, the front side of the arc-shaped wiper is provided with multiple water inlets, which are evenly distributed.

[0010] In some embodiments, the lower end face of the arc-shaped wiper part forms a receiving cavity, which is connected to the water inlet, and the upper end face of the arc-shaped wiper part forms a water outlet, which is connected to the receiving cavity.

[0011] In some embodiments, a connecting part is connected to the water outlet, which can be connected to a water suction fan.

[0012] In some embodiments, the connecting part includes a base and a connecting rod, the base is located at the water outlet, the connecting rod is connected to the base, and a water outlet groove is formed on the base.

[0013] In some implementations, the arc-shaped wiper section is also provided with a guide wheel.

[0014] In this invention, a squeegee is installed behind a floor scrubber. After the floor scrubber finishes cleaning the floor, water remains on the floor. The squeegee moves with the floor scrubber. When the suction fan on the squeegee is started, the water remaining on the floor enters the receiving cavity through the water inlet and is discharged from the receiving cavity to the water outlet. The water at the water outlet reaches the suction fan through the connecting part. The suction fan discharges and collects the water, completing the entire water suction action.

[0015] The floor scrubber of this invention is equipped with a pressure strip, and two pressure plates can hold the pressure strip in place. The pressure strip can press the curved squeegee tightly, so that when the curved squeegee comes into contact with the ground, the lower end of the curved squeegee will not lift up, forming a relatively sealed structure between the bottom of the curved squeegee and the ground, resulting in better water absorption. In addition, the base of the connecting part of this invention is formed with a water outlet groove, which can prevent the absorbed water from flowing back onto the ground and affecting the water absorption effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Figures 1-4 The diagram schematically illustrates the structure of the squeegee of a floor scrubber according to one embodiment of the present invention.

[0024] like Figures 1-4 As shown, a floor scrubber's squeegee includes an arc-shaped squeegee section 1. A water inlet 11 is formed at the lower end of the arc-shaped squeegee section 1. A suction fan can be installed on the arc-shaped squeegee section 1. The arc-shaped squeegee section 1 scrapes residual water from the floor into a receiving cavity 16. The suction fan can extract the water from the receiving cavity 16. In this embodiment, the suction fan is a negative pressure fan, an existing power device. Its specific structure and principle will not be elaborated further. After the floor scrubber completes scrubbing, the residual water on the floor enters the arc-shaped squeegee section 1 through the water inlet 11 and is sucked out by the suction fan. Pressure strips 1 are installed on both the front and rear sides of the arc-shaped squeegee section 1. 2. Pressure plates 13 are installed at both ends of the arc-shaped wiper 1. The two pressure plates 13 can hold the pressure strips 12 on the front and rear sides of the arc-shaped wiper 1. The pressure strips 12 can press down the lower middle part of the arc-shaped wiper 1. The lower end face of the arc-shaped wiper 1 is a soft structure made of rubber material. When the lower end face of the arc-shaped wiper 1 is in contact with the ground, the lower end face of the arc-shaped wiper 1 can form a relatively sealed structure with the ground (of course, the water inlet 11 is not sealed with the ground, and residual water can enter the receiving cavity 16 of the arc-shaped wiper 1 from the water inlet 11). The pressure strips 12 can prevent the lower middle part of the arc-shaped wiper 1 from lifting up and affecting the water suction effect of the water suction fan.

[0025] like Figure 1 and Figure 4As shown, in this embodiment, the pressure strip 12 is arc-shaped, and a receiving groove 131 is formed in the middle of the pressure plate 13. The left pressure plate 13 is secured to the left end of the arc-shaped wiper part 1 through the receiving groove 131, and the left pressure plate 13 can secure the left ends of the two pressure plates 13. The right pressure plate 13 is secured to the right end of the arc-shaped wiper part 1 through the receiving groove 131, and the right pressure plate 13 can secure the right ends of the two pressure plates 13. Therefore, the two pressure plates 13 can secure the two pressure strips 12, preventing the pressure strips 12 from falling off the arc-shaped wiper part 1 on their own. This method also makes it easier to disassemble and install the arc-shaped wiper part 1. The two pressure plates 13 and the pressure strips 12 can press the lower middle part of the arc-shaped wiper part 1 tightly, preventing the lower middle part of the arc-shaped wiper part 1 from tilting up and affecting the water suction effect of the suction fan.

[0026] like Figure 4 As shown, in this embodiment, positioning protrusions 15 are formed on both the front and rear sides of the arc-shaped wiper part 1, and positioning grooves are provided at corresponding positions of the pressure strip 12. The positioning grooves can be locked onto the positioning protrusions 15. The positioning protrusions 15 are arranged along the length direction of the arc-shaped wiper part 1 (lateral), and similarly, the positioning grooves are also arranged along the length direction of the pressure strip 12 (lateral). By forming positioning protrusions 15 on the front and rear sides of the arc-shaped wiper part 1, the installation of the pressure strip 12 can be assisted. That is, the positioning grooves of the pressure strip 12 can be locked onto the protrusions 15. At the same time, the left and right ends of the pressure strip 12 are aligned, and then the pressure plate 13 is installed to complete the installation of the pressure strip 12.

[0027] like Figure 1 and Figure 4 As shown, in this embodiment, multiple water inlets 11 are integrally formed on the front side (i.e. the side facing the floor scrubber) of the arc-shaped squeegee 1. The multiple water inlets 11 are evenly distributed. When the squeegee of the floor scrubber of this invention is placed on the ground to absorb water, the rest of the arc-shaped squeegee 1 will form a relatively sealed structure with the ground, so that water can only enter the arc-shaped squeegee 1 from the water inlets 11, thereby improving the water absorption efficiency.

[0028] In this embodiment, as Figure 2 As shown, a receiving cavity 16 is formed on the lower end face of the arc-shaped wiper part 1, and the receiving cavity 16 is connected to the water inlet 11. A water outlet 17 is formed on the upper end face of the arc-shaped wiper part 1, and the water outlet 17 is connected to the receiving cavity 16. When the water suction fan is working, the water suction fan can suck water on the ground from the water inlet 1 into the receiving cavity 16. The water in the receiving cavity 16 enters the water suction fan from the water outlet 17 and is discharged by the water suction fan into the corresponding water receiving container, cleaning up the water remaining on the ground.

[0029] like Figure 3 and Figure 4As shown, in this embodiment, a connecting part 2 is connected to the water outlet 17. The connecting part 2 can be connected to the water suction fan. The structure of the connecting part 2 can be as follows: Figure 3 and Figure 4 As shown, the connecting part 2 can be fixedly installed on the upper end face of the arc-shaped wiper part 1 by screws. At the same time, the connecting part 2 can be connected to the water suction fan through a pipe.

[0030] like Figure 3 and Figure 4 As shown, the connecting part 2 in this embodiment includes a base 21 and a connecting rod 22. The base 21 can be fixedly installed at the water outlet 17. The base 21 can be fixed by welding or screws, etc. The connecting rod 22 can be connected to the base 21 by screws. The base 21 and the connecting rod 22 are connected as a whole. The base 21 can be integrally formed with a water outlet groove 211. When the water suction fan stops working, due to the loss of negative pressure, the residual water in the water suction fan pipe will flow from the end of the pipe into the water outlet groove 211. The water outlet groove 211 can hold a part of the water to prevent the water from flowing back from the water outlet 17 and falling back onto the ground, causing unnecessary trouble.

[0031] like Figures 1-3 As shown, the arc-shaped wiping section 1 is also equipped with a guide wheel 14. Therefore, by providing the guide wheel 14, the arc-shaped wiping section 1 will not directly collide with the wall or other surfaces during use.

[0032] In this invention, after the floor scrubber finishes washing the floor, water will remain on the floor. At this time, the squeegee will move with the floor scrubber. After the suction fan on the squeegee is started, the water remaining on the floor will enter the receiving cavity from the water inlet 11 and be discharged from the receiving cavity to the water outlet. The water at the water outlet will reach the suction fan through the connecting part 2. The suction fan will discharge and collect the water, completing the entire water suction action.

[0033] The floor scrubber of this invention is equipped with a pressure strip, and two pressure plates can hold the pressure strip in place. The pressure strip can press the curved squeegee tightly, so that when the curved squeegee comes into contact with the ground, the lower end of the curved squeegee will not lift up, forming a relatively sealed structure between the bottom of the curved squeegee and the ground, resulting in better water absorption. In addition, the base of the connecting part of this invention is formed with a water outlet groove, which can prevent the absorbed water from flowing back onto the ground and affecting the water absorption effect.

[0034] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
