Description

Technical Field

[0001] This utility model relates to the field of floor scrubber technology, specifically to a floor scrubber brush pressure adjustment mechanism. Background Technology

[0002] Floor scrubbers are commonly used cleaning equipment and are widely used in various scenarios such as shopping malls, factories, and stations. They clean stains by contacting and rubbing the brushes with the ground. The appropriateness of the brush pressure on the ground directly affects the cleaning effect and the protection effect of the ground. Therefore, adjusting the brush pressure on the ground is an important part of floor scrubbers.

[0003] Currently, most floor scrubbers rely solely on the weight of the brush assembly or a fixed pressure structure to achieve contact, making it impossible to flexibly adjust the pressure. When faced with different floor materials and diverse cleaning needs, fixed pressure can easily lead to uneven cleaning results. Soft floors may be damaged due to excessive pressure, while rough floors may be difficult to remove stubborn stains due to insufficient pressure.

[0004] Therefore, we propose a floor scrubber brush pressure adjustment mechanism to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a floor scrubber brush pressure adjustment mechanism to solve the problem mentioned in the background art that existing adjustment mechanisms cannot flexibly adjust the pressure when faced with different floor materials and diverse cleaning needs.

[0007] Preferably, there are two horizontal plates and two electric actuators symmetrically arranged about the axis of the mounting bracket, and the screw holes are symmetrically arranged about the horizontal plates.

[0008] Preferably, the floor cleaning assembly includes a motor fixed on the mounting cover, a drive shaft fixed to the output end of the motor, a turntable fixed to the bottom of the drive shaft, and a brush fixed to the bottom surface of the turntable.

[0009] Preferably, a sleeve is fixed inside the mounting cover, a groove is provided inside the sleeve, a sliding plate is engaged and slidable in the groove, a rotating rod is rotatable inside the sliding plate, a gear is fixed to the bottom surface of the rotating rod, and a brush is fixed to the bottom surface of the gear.

[0010] Preferably, a gear ring is fixed on the top surface of the turntable, and the gear ring meshes with the gear.

[0011] This utility model has the following beneficial effects: 1. This utility model allows for flexible adjustment of the contact pressure between the brush and the ground, adapting to different ground materials and diverse cleaning needs, effectively solving the problem of uneven cleaning results caused by fixed pressure in existing technologies. The force is evenly distributed and highly stable during adjustment, avoiding imbalance, ensuring smooth cleaning operations, and improving the overall cleaning experience and results.

[0012] 2. This utility model expands the cleaning coverage of the floor scrubber, reduces cleaning dead spots, and makes the cleaning process more even and comprehensive.

[0020] 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.

[0021] Example 1: This embodiment aims to address the problem of uneven cleaning results caused by the inability of existing floor scrubbers to flexibly adjust the contact pressure between the brushes and the floor. Please refer to [link / reference needed]. Figure 1 - Figure 4 A floor scrubber brush pressure adjustment mechanism includes a mounting cover 1, an adjustment component 2 on the mounting cover 1, the adjustment component 2 includes a horizontal plate 21, a screw hole 22 on the horizontal plate 21, an electric push rod 23 fixed on the bottom surface of the horizontal plate 21, and a mounting bracket 24 fixed at the output end of the electric push rod 23. The mounting bracket 24 is fixedly connected to the mounting cover 1.

[0022] There are two horizontal plates 21 and two electric actuators 23 symmetrically arranged about the axis of the mounting bracket 24, and screw holes 22 are symmetrically arranged about the horizontal plate 21.

[0023] In this embodiment: During use, the mounting cover 1 is fixedly connected to the floor scrubber via the screw holes 22 on the horizontal plate 21. After assembly, the floor scrubber can be started. After the floor scrubber is started, it drives the brush to rotate, and the stains are cleaned by the contact friction between the brush and the ground.

[0024] When pressure needs to be adjusted during the cleaning process, the electric actuator 23 can be operated. The horizontal plate 21 and the electric actuator 23 are symmetrically arranged about the axis of the mounting frame 24, and the screw holes 22 are symmetrically distributed on the horizontal plate 21, which can ensure the stability and uniform force distribution during the pressure adjustment process. After the electric actuator 23 is started, it drives the mounting frame 24 to rise and fall. When the mounting frame 24 moves down, the brush 1 34 and brush 2 311 installed at the bottom move down synchronously, increasing the contact pressure between the brush and the ground. When the electric actuator 23 retracts, the mounting frame 24 drives the brush to move up, reducing the contact pressure, thereby realizing flexible adjustment of the brush pressure on the ground to adapt to different ground conditions and cleaning needs.

[0025] Example 2: This embodiment aims to address the limitations of existing floor scrubbers in terms of cleaning coverage and effectiveness in removing stubborn stains. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1 - Figure 6 The mounting cover 1 is equipped with a floor cleaning component 3. The floor cleaning component 3 includes a motor 31 fixed on the mounting cover 1. A drive shaft 32 is fixed to the output end of the motor 31. A turntable 33 is fixed to the bottom of the drive shaft 32. A brush 34 is fixed to the bottom surface of the turntable 33.

[0026] A sleeve 36 is fixed inside the mounting cover 1. A groove 37 is provided inside the sleeve 36. A sliding plate 38 is engaged and slidable inside the groove 37. A rotating rod 39 rotates inside the sliding plate 38. A gear 310 is fixed to the bottom surface of the rotating rod 39. A brush 311 is fixed to the bottom surface of the gear 310. A gear ring 35 is fixed to the top surface of the turntable 33. The gear ring 35 and the gear 310 mesh with each other.

[0027] In this embodiment: After the overall assembly is completed by connecting the mounting cover 1 to the floor scrubber, the floor scrubber starts and enters the cleaning operation state. After the motor 31 starts, it drives the transmission shaft 32, which drives the turntable 33 to rotate synchronously. The brush 34 on the bottom surface of the turntable 33 rotates accordingly, realizing basic large-area cleaning.

[0028] The built-in bracket 36 of the mounting cover 1 provides sliding support for the slide plate 38, which can move flexibly within the groove 37 of the bracket 36. The rotating rod 39 rotates within the slide plate 38, ensuring that the gear 310 and the second brush 311 remain rotatable. The gear ring 35 on the top surface of the turntable 33 rotates with the turntable 33, meshing with the gear 310 and causing the gear 310 to rotate in the opposite direction, thus allowing the second brush 311 to rotate in the opposite direction with the first brush 34. The forward rotation of the first brush 34 and the reverse rotation of the second brush 311 work together to expand the cleaning coverage area and enhance the frictional cleaning power for stubborn stains on the floor, making the cleaning process more even and comprehensive, and effectively improving the overall cleaning quality.

[0029] During cleaning operations, the floor scrubber delivers cleaning fluid through its built-in water system. The fluid is then directed to the brush mounting area via a pre-designed guide channel in the mounting cover 1. The cleaning fluid directly wets the bristles of brush one (34) and brush two (311), achieving a simultaneous water output and brushing operation. It should be noted that the water output method and the connection structure between the brushes and the water system described above are existing technologies and not the main innovations of this solution; therefore, they will not be described in detail here.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
