Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning robot. Background Art

[0002] Existing cleaning robots, such as window cleaning robots, often moisten glass surfaces by spraying water mist to reduce cleaning effort. Because water needs to be supplied to the spray assembly, the machine requires a water tank, typically located internally. Sensors monitor the water level to indicate the amount of water being used. The need for sensors increases costs. Utility Model Content

[0003] The utility model aims to provide a cleaning robot which can facilitate observation of water volume and reduce costs.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a cleaning robot includes a body, on which is provided a spray assembly and a water tank connected to the spray assembly, the bottom of the water tank is transparent and close to or embedded in a transparent area provided at the bottom of the body, or passes through the bottom of the body and is exposed to the outside, so that the user can directly observe the amount of water in the water tank from the bottom of the body.

[0005] Furthermore, a negative pressure chamber is provided on the machine body and a suction module is provided in the negative pressure chamber for extracting air in the chamber so that the machine can be adsorbed on the surface to be cleaned. The water tank is close to the negative pressure chamber and dissipates heat by absorbing the heat emitted by the suction module through the water in the water tank.

[0006] Furthermore, the water tank surrounds the negative pressure chamber.

[0007] Furthermore, the negative pressure chamber is surrounded by a water tank from the top to the bottom.

[0008] Furthermore, the bottom of the water tank is a transparent bottom shell and an annular shell is installed on the bottom shell. The annular side wall in the middle of the shell surrounds the negative pressure cavity and a through hole is provided on the bottom shell.

[0009] Furthermore, the bottom of the water tank and the transparent area at the bottom of the body are both made of acrylic or polycarbonate.

[0010] Furthermore, the bottom of the water tank is embedded in the transparent area of the bottom of the body and is connected therewith as a whole.

[0011] The utility model makes the bottom of the water tank transparent and makes it close to or embedded in the transparent area of the bottom of the body or passes through the bottom of the body and is exposed to the outside, so that the user can intuitively observe the water level in the water tank (for example, when the cleaning robot is wiping the window glass, the user indoors can observe the water level in the water tank at the bottom of the machine through the glass), which improves the user experience. At the same time, there is no need to rely on electronic sensors, eliminating the use of sensors, thereby reducing production and maintenance costs, avoiding false alarms or missed alarms due to sensor failure, and improving the safety of the cleaning robot during use.

[0026] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0027] like Figure 1-8 As shown, this embodiment provides a cleaning robot, which includes a body 1, on which is disposed a cleaning portion for performing a cleaning function, such as a cleaning turntable or a cleaning rag 6, and a walking portion for driving the robot, such as a crawler structure 7 or walking wheels, at the bottom of the body 1. Since the cleaning principle, walking mechanism, and control principle of the cleaning robot of this embodiment are similar to those of existing cleaning robots, they will not be described in detail here.

[0028] Similar to existing cleaning robots, a spray assembly 2 is also provided on the body 1 of this embodiment. The spray assembly 2 can be used to spray water mist onto the surface to be cleaned (such as glass) to wet the surface to be cleaned. Of course, the spray assembly 2 can also be configured to spray water onto a rag to wet the rag for easier wiping of the glass. The spray assembly 2 is connected to a water tank 3 that supplies water to it. The spray assembly 2 and the water tank 3 can be connected via a pipeline (such as a hose), and the water tank 3 is provided in the body 1. Usually, a set of spray assemblies 2 is provided at the front and rear ends of the body 1, and these two sets of spray assemblies 2 can be connected to the pipeline interfaces at the front and rear ends of the water tank 3 respectively via pipelines. The spray assembly 2 involved can adopt existing technology, such as a piezoelectric ceramic microporous atomizer, and the atomizer is used to achieve water atomization. The improvement of this embodiment does not lie in this, so it will not be described in detail. Unlike existing cleaning robots, the bottom of the water tank 3 in this embodiment is transparent (of course, the entire water tank 3 can also be transparent). The water tank 3 can directly pass through the bottom of the body 1 and be exposed to the outside. In this way, the remaining water in the water tank 3 can be seen from the bottom of the body 1 directly through the transparent bottom of the water tank 3. Alternatively, a transparent area is provided at the bottom of the body 1, and the transparent bottom of the water tank 3 is close to or embedded in the transparent area at the bottom of the body 1. In this way, the remaining water in the water tank 3 can be seen from the bottom of the body 1 directly through the transparent area at the bottom of the body 1 and the transparent bottom of the water tank 3. There are many ways to expose the water tank 3 through the bottom of the body 1. For example, a penetrating installation port 1a is provided at the bottom of the body 1, and the bottom of the water tank 3 is installed in the installation port 1a. In this way, the installation port 1a forms a window for observing the water level, which can be seen in FIG. Figure 1 、 2. Among them, the water tank 3 and the body 1 can be two independent components, or they can be connected as one. For example, the bottom of the water tank 3 is embedded in the transparent area at the bottom of the body 1 and connected thereto as a whole. Then, when the shape, size and position of the transparent area at the bottom of the water tank 3 and the bottom of the body 1 are the same, the transparent bottom of the water tank 3 is the transparent area at the bottom of the body 1. Through the above-mentioned arrangement, the user only needs to observe from the bottom of the body 1 to intuitively see the amount of water in the water tank 3 without using any electronic equipment or sensors, which makes it convenient for the user to understand the water level in time and replenish water. For example, when the cleaning robot is wiping the window glass, the user in the room can see the water level in the water tank 3 at the bottom of the machine through the glass in real time. This intuitive feedback can improve the user's experience. Moreover, by reducing the use of electronic components, not only can the equipment cost be reduced, but also the risk of system failure due to sensor failure can be reduced, thereby improving overall reliability.

[0029] The cleaning robot of this embodiment can be used not only to clean floors and floors, but also to clean window glass. Since the cleaning robot needs to adhere to the glass when cleaning windows, it is necessary to equip it with a suction module 5. Specifically, a negative pressure chamber 4 is provided within the body 1, extending to the bottom of the body 1. The bottom of the body 1 is provided with numerous through-holes connecting the negative pressure chamber 4 with the outside world. The suction module 5 is disposed within the negative pressure chamber 4 of the body 1 and generates negative pressure suction by extracting air from the negative pressure chamber 4, allowing the cleaning robot to adhere to the surface to be cleaned. The suction module 5 includes, but is not limited to, a negative pressure blower or vacuum pump. During operation, it generates heat. To dissipate the heat generated by the suction module 5, a water tank 3 can be positioned close to the negative pressure chamber 4. This allows the water in the water tank 3 to absorb some of the heat dissipated by the suction module 5, thereby dissipating the heat. In this way, the water tank 3 not only stores water for spraying but also dissipates heat, achieving multiple uses and enhancing practicality.

[0030] The water in the water tank 3 of this embodiment can absorb the heat generated by the suction module 5 during operation, primarily through the natural cooling properties of water, achieving efficient water-cooling and heat dissipation, thereby ensuring the stability and safety of the robot during long-term operation. Furthermore, the water tank 3 can surround the negative pressure chamber 4. This not only fully utilizes the internal space of the machine body 1, making the machine structure more compact and the overall appearance more miniaturized, but also absorbs the heat generated by the suction module 5 within the negative pressure chamber 4 over a larger area and to a greater extent, further reducing the impact of heat on the internal components of the machine and extending the machine's life.

[0031] Furthermore, the water tank 3 can also extend from the top of the negative pressure chamber 4 to the bottom of the negative pressure chamber 4, so that the top to the bottom area of the negative pressure chamber 4 are surrounded by the water tank 3 (which can also be understood as covering). In this way, the water tank 3 can cover the entire height of the negative pressure chamber 4, which helps to more evenly disperse and absorb the heat generated by the suction module 5 and avoid local overheating. This design also increases the contact area between the water tank 3 and the negative pressure chamber 4, which can more effectively transfer heat from the suction module 5 to the water in the water tank 3, thereby accelerating the heat dissipation rate. Moreover, the vertical extension of the water tank 3 also provides additional structural support for the negative pressure chamber 4, enhancing the overall stability and durability.

[0032] In this embodiment, if Figure 4-8 As shown, the bottom of the water tank 3 is a transparent bottom shell 3a, on which an annular housing 3b is mounted (usually in a sealed connection). The cavity formed by the annular sidewall in the middle of the housing 3b serves as the negative pressure chamber 4, and a through hole is provided in the center of the bottom shell 3a. This further improves the heat dissipation effect and eliminates the need for a mounting shell that would otherwise serve as the negative pressure chamber 4. The suction module 5 can be directly mounted within the annular sidewall of the annular housing 3b, resulting in a more compact structure. To facilitate the installation of the suction module 5 within the negative pressure chamber 4, the housing 3b and bottom shell 3a can be configured as a detachable structure.

[0033] Among them, the bottom of the water tank 3 and the transparent area at the bottom of the machine can both be made of transparent materials such as acrylic or polycarbonate. Of course, the water tank 3 can also be made of transparent materials as a whole. Among them, the bottom of the water tank 3 is a transparent material, that is, the transparent bottom shell 3a is a transparent material, taking it as an example of acrylic material. Acrylic material has good transparency, allowing users to clearly observe the water level in the water tank 3, making it convenient to replenish water in time. Compared with traditional glass or other transparent materials, acrylic material is lighter, which helps to reduce the overall weight of the cleaning robot, and the cost of acrylic material is relatively low, which helps to reduce production costs. Moreover, acrylic material is easy to process and shape, and has high impact resistance and is not easy to break.

[0034] In general, this embodiment sets the bottom of the water tank 3 to be transparent, and sets the bottom of the body 1 at the corresponding position to be transparent or exposes the bottom of the water tank 3 outside the bottom of the body 1, so that the user can intuitively observe the water level in the water tank 3. Especially when the cleaning robot is wiping the window glass, the user in the room can intuitively observe the water level in the water tank 3 at the bottom of the machine through the glass, which improves the user experience. At the same time, there is no need to rely on electronic sensors, eliminating the use of sensors, thereby reducing production costs and maintenance costs, and avoiding false alarms or missed alarms due to sensor failures, thereby improving the safety of the cleaning robot during use.
