Description

Technical Field

[0001] This utility model relates to the field of intelligent cleaning equipment technology, and in particular to a floating cleaning turntable and a cleaning robot including the turntable. Background Technology

[0002] The cleaning robot disclosed in Chinese patent document CN117484524A uses wheels to move across the surface to be cleaned. During the movement, a continuously rotating cleaning disc constantly wipes the surface to be cleaned to perform the cleaning function. The cleaning disc floats as a whole by using an elastic element (such as an elastic silicone ring) between the cleaning disc and the machine body. Because the cleaning disc can float upwards relative to the machine body, the wheels are also pressed firmly against the surface to be cleaned while the cleaning disc is in contact with it. Although this floating structure can ensure the cleaning effect and walking stability (preventing slippage) of the cleaning robot in the early stages, the elastic element that enables the cleaning disc to float is located inside the housing above the disc. The elastic material is prone to aging and deformation under compression during use. Users often cannot detect when the elastic element inside the housing needs replacement, inevitably leading to a decrease in the contact between the cleaning disc and the surface to be cleaned, and a decline in cleaning effect after a period of use. Even if users suspect that the elastic component supporting the cleaning turntable needs to be replaced, the need to disassemble the entire casing would still present inconvenience for maintenance. Utility Model Content

[0003] One of the purposes of this invention is to provide an improved floating structure cleaning turntable, which not only better ensures the cleaning effect of the cleaning robot, but also makes it easier for users to maintain and operate it during daily use.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a floating cleaning turntable, comprising:

[0005] Rotary chuck;

[0006] The cloth mounting base is installed below the rotating chuck via a hook structure and is configured to float upward relative to the rotating chuck.

[0007] The cloth, which is shaped like a bag, is fitted onto the outside of the cloth mounting base. The open end of the cloth is clamped between the rotating chuck and the cloth mounting base and is configured such that the clamped part can be compressed and deformed when the cloth mounting base floats upward relative to the rotating chuck.

[0008] Furthermore, the open end of the cloth is provided with a first anti-detachment structure to prevent the cloth from falling off when it is clamped between the rotating chuck and the cloth mounting base.

[0009] Furthermore, the first anti-detachment structure includes an anti-detachment protrusion located at the open end of the cloth.

[0010] Furthermore, the lower end of the rotary chuck is provided with multiple concentrically spaced annular pressing parts, which cooperate with the cloth mounting base to jointly clamp the open end of the cloth.

[0011] Furthermore, the cloth mounting base is a ring structure, and its inner sidewall is provided with multiple radially inward protrusions;

[0012] The lower middle part of the rotary chuck is provided with an axially extending mating part, and the outer peripheral surface of the mating part is provided with an axially extending sliding groove. The sliding groove is clearance-fitted with the protrusion so that the cloth mounting seat can float axially relative to the rotary chuck.

[0013] As a preferred embodiment, the hook structure includes a limiting flange located at the lower end of the mating portion. The limiting flange extends radially outward from the mating portion to form a blocking portion, which is used to prevent the protrusion from disengaging downward from the groove.

[0014] As another preferred embodiment, the mating part includes a plurality of mating blocks distributed circumferentially, the sliding groove is provided on the mating blocks, and an intermittent space is formed between adjacent mating blocks;

[0015] The protrusions on the inner wall of the cloth mounting base are set to correspond to the positions of each intermittent space, forming limiting protrusions;

[0016] The hook structure includes an axially extending extension located at the lower end of the rotating chuck and corresponding to each intermittent spatial position. The outer side of the extension is provided with a radially outward protruding anti-detachment boss, which forms an axial limiting fit with the limiting boss.

[0017] Another objective of this utility model is to provide a cleaning robot, which includes a body, and the bottom of the body is provided with a cleaning turntable with the above-mentioned floating structure.

[0018] This invention employs a floating connection structure between the rotating chuck on the outside of the casing and the cloth mounting base. During cleaning, the cloth mounting base moves upward under the reaction force of the surface to be cleaned, causing compression deformation of the clamped part of the cloth, thus achieving the floating function. Since the cloth is a consumable item during the use of the cleaning robot, users typically replace it monthly (usually once a month), thus avoiding problems such as poor adhesion between the cleaning turntable and the surface to be cleaned due to aging of the elastic components (insufficient elasticity). Even if poor adhesion does occur, users can simply replace the cloth located on the outside of the casing, making the operation very convenient. Attached Figure Description

Detailed Implementation

[0027] To facilitate a clearer understanding of the concept of this utility model by those skilled in the art, the following description, in conjunction with embodiments and accompanying drawings, will provide a further explanation. Example 1

[0028] like Figure 1-5As shown, this embodiment provides an improved floating structure cleaning turntable, mainly including a rotating chuck 1a, a cloth mounting base 1b, and a cloth 1c. The rotating chuck 1a serves as the main support structure of the cleaning turntable 1; the cloth mounting base 1b is installed below the rotating chuck 1a via a hook structure and can float upwards relative to the rotating chuck 1a; the cloth 1c is generally bag-shaped (also called a "cloth bag" or "cloth ring") and is fitted over the cloth mounting base 1b. Typically, the upper end of the cloth 1c is open, but depending on the requirements, the lower end of the cloth 1c can also be open, but it should ensure that it has the corresponding cleaning coverage capacity. The cloth mounting base 1b achieves axial floating through its cooperation structure with the rotating chuck 1a. The open end (upper end) of the cloth 1c is clamped between the rotating chuck 1a and the cloth mounting base 1b, and is configured such that the clamped part can be compressed and deformed when the cloth mounting base 1b floats upwards relative to the rotating chuck 1a. The cleaning turntable 1 is located at the bottom of the cleaning robot's body 2. The body 2 includes a housing, and the rotating chuck 1a and the cloth mounting base 1b are both located outside the housing. In this embodiment, a floating connection structure is used between the rotating chuck 1a and the cloth mounting base 1b outside the housing. During the cleaning operation, the cloth mounting base 1b moves upward under the reaction force of the surface to be cleaned, causing the clamped part of the cloth 1c to be compressed and deformed, thereby realizing the floating function. Since the cloth 1c is a consumable during the use of the cleaning robot, the user's usage cycle for the cloth 1c is relatively short (generally replaced once a month). Usually, there will be no problem of poor adhesion between the cleaning turntable 1 and the surface to be cleaned due to the aging of the elastic component (insufficient elasticity). Even if the adhesion between the cleaning turntable 1 and the surface to be cleaned becomes poor, the user only needs to replace the cloth 1c located outside the housing to solve the problem, which is very convenient.

[0029] To prevent the cleaning cloth 1c from detaching from the clamping point between the rotating chuck 1a and the cleaning cloth mounting base 1b during cleaning operations, this embodiment provides a first anti-detachment structure at the open end of the cleaning cloth 1c. This first anti-detachment structure includes, but is not limited to, an anti-detachment protrusion 1c1 located at the open end of the cleaning cloth 1c (see...). Figure 3-5 In addition, other equivalent anti-detachment designs (such as anti-detachment grooves, anti-detachment ribs, etc.) are used. Through the cooperation of the first anti-detachment structure with the rotating chuck 1a and the cloth mounting seat 1b, the external force during the cleaning process can be resisted, preventing the cloth 1c from accidentally falling off the mounting position, thereby improving the operational reliability and stability of the cleaning turntable.

[0030] In this embodiment, the lower end of the rotary chuck 1a is provided with a plurality of concentrically spaced annular pressing portions 1a1, see [reference]. Figure 2 , 45. These holding parts 1a1 cooperate with the cloth mounting base 1b to form a clamping space for fixing the open end of the cloth 1c. When pressure is applied during cleaning operations, the annular holding parts 1a1 and the cloth mounting base 1b work together to ensure that the cloth 1c is firmly clamped and prevent displacement or loosening.

[0031] In this embodiment, the cloth mounting base 1b has a ring-shaped structure, and its inner sidewall is provided with a plurality of radially inward protrusions 1b1, see [reference]. Figure 3 The lower middle part of the rotary chuck 1a has an axially extending mating part 1a2, and the outer peripheral surface of the mating part 1a2 has an axially extending sliding groove 1a2a1. See [reference needed]. Figure 2 The protrusion 1b1 and the slide groove 1a2a1 are fitted with a clearance, allowing the cloth mounting base 1b to float axially relative to the rotating chuck 1a. Furthermore, a second anti-detachment structure (i.e., the aforementioned hook structure) is provided between the cloth mounting base 1b and the rotating chuck 1a to prevent the protrusion 1b1 from detaching axially downwards from the slide groove 1a2a1, thus preventing separation during floating. Through the clearance fit between the protrusion 1b1 and the slide groove 1a2a1, the axial floating function of the cloth mounting base 1b relative to the rotating chuck 1a is achieved, allowing the cleaning turntable 1 (cloth mounting base 1b) to adaptively adhere to the cleaning surface while ensuring that the traveling wheels also stably press against the cleaning surface. Simultaneously, the second anti-detachment structure (hook structure) prevents the protrusion 1b1 from detaching from the slide groove 1a2a1 during floating, ensuring the connection stability between the cloth mounting base 1b and the rotating chuck 1a, and enhancing the reliability and durability of the entire cleaning turntable.

[0032] The second anti-detachment structure (hook structure) can be implemented in any of the following ways:

[0033] Option 1 (not shown in the figure): A radially outwardly extending (protruding) limiting flange is provided at the lower end of the mating part 1a2 to form a blocking part. The annular blocking surface of the limiting flange restricts the downward movement of the protrusion 1b1, preventing it from disengaging from the slide groove 1a2a1. The blocking part can adopt a continuous annular structure or an intermittent arc-shaped structure.

[0034] Method 2 (see Figure 2-5The mating part 1a2 is decomposed into multiple mating blocks 1a2a spaced circumferentially. A sliding groove 1a2a1 is provided on each mating block 1a2a, forming an intermittent space between adjacent mating blocks 1a2a. Some protrusions 1b1 on the inner wall of the cloth mounting base 1b are positioned corresponding to each intermittent space, forming limiting protrusions 1b1a. The remaining protrusions 1b1 form mating protrusions 1b1b that fit with the sliding groove 1a2a1 with clearance. An axially extending extension 1a3 is provided at the lower end of the rotating chuck 1a corresponding to each intermittent space. The outer surface of the extension 1a3 has a radially outwardly protruding anti-detachment boss 1a3a. The anti-detachment boss 1a3a and the limiting protrusion 1b1a can form an axial limiting fit. When the protrusion 1b1 (matching protrusion 1b1b) slides into the groove 1a2a1 on the mating block 1a2a, the anti-detachment protrusion 1a3a can block and limit the protrusion 1b1a from below, preventing the protrusion 1b1 (matching protrusion 1b1b) from disengaging downward from the groove 1a2a1.

[0035] This embodiment uses the second anti-detachment structure (hook structure) of method two. For example... Figure 3 As shown, the protrusions 1b1 (including limiting protrusions 1b1a and mating protrusions 1b1b) provided on the inner sidewall of the cloth mounting base 1b can be configured to be evenly distributed along the circumference, and each protrusion 1b1 is arranged at equal angles in the circumferential direction, so that the cloth mounting base 1b can be assembled with the rotating chuck 1a at multiple mounting phase angles, reducing the difficulty of assembly alignment. Example 2

[0036] This embodiment provides a cleaning robot that integrates the improved cleaning turntable of Embodiment 1 while maintaining the basic functional architecture of a traditional cleaning robot. Specifically, as... Figure 1-6 As shown, the cleaning robot includes a body 2 (including a housing) and a cleaning turntable 1 located at the bottom of the body 2 (as described in Embodiment 1). It also includes a suction module mounted on the body 2 for adsorbing the robot onto the surface to be cleaned, and a drive module (e.g., wheels 3) for propelling the robot along the surface. These functional modules and their working principles are similar to those of existing cleaning robots and will not be described in detail here for simplicity. The aforementioned surface to be cleaned includes, but is not limited to, the surface of a panel (e.g., floor, glass window, glass curtain wall, etc.).

[0037] The above embodiments are preferred implementations of this utility model. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
