Description

Technical Field

[0001] This utility model relates to the field of cleaning robots, specifically a water leakage detection device for cleaning robots. Background Technology

[0002] Cleaning robots are automated home appliances that integrate intelligent control, sensor technology, and cleaning functions. Their core value lies in replacing manual labor to complete floor cleaning tasks through technological innovation. They are typically equipped with navigation systems (such as lidar and visual recognition), drive wheels, and various cleaning components, enabling them to autonomously plan paths and perform operations such as sweeping, vacuuming, and mopping. Some high-end models also have advanced functions such as automatic dust collection, wastewater separation, or UV disinfection.

[0003] In traditional cleaning robots, leaks can easily occur due to loose connections between the water pipe and the water tank during operation. This not only affects cleaning performance but may also damage internal components. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a water leakage detection device for cleaning robots. This device solves the technical problem that the interface between the water outlet pipe and the water tank is loose during the operation of current cleaning robots, which can easily lead to water leakage. This not only affects the cleaning effect but may also damage the internal components of the machine.

[0005] To achieve the objective of this utility model, the technical solution adopted is as follows: A water leakage detection device for a cleaning robot is designed, comprising:

[0006] The water outlet pipe is located at the water outlet end of the cleaning robot's water tank;

[0007] A leak detection mechanism is used to detect the sealing condition at the connection between the water outlet pipe and the water tank. The leak detection mechanism includes:

[0008] A sleeve is fitted onto the connection between the water outlet pipe and the water tank, with one end of it sealed and fixedly connected to the water tank.

[0009] The mounting cylinder has a hollow cylindrical structure with one end open. At the center of its bottom away from the open end, there is a through hole for the water outlet pipe to pass through. The mounting cylinder is coaxially sleeved on the outside of the water outlet pipe through the through hole, and the inner wall of the mounting cylinder and the outer wall of the sleeve are screwed together by a threaded structure.

[0010] A water level detection component is disposed at the bottom of the inner cavity of the sleeve and is used to detect changes in the liquid water level in the sealed cavity between the mounting cylinder and the sleeve.

[0011] Preferably, the water level detection component is a water level sensor, and the water level detection component is connected to an external alarm after the signal is processed by a control processor in the prior art.

[0012] Preferably, an exhaust pipe is fixedly installed on the top of the sleeve, the inner cavity of the exhaust pipe is connected to the inner cavity of the sleeve, and a water-stopping mechanism is provided on the top of the inner cavity of the sleeve.

[0013] Preferably, the water-stopping mechanism includes:

[0014] A water-stop block, wherein one end of the water-stop block has a circular hole, and the bottom of the inner cavity of the circular hole is hemispherical; the top of the water-stop block is fixedly connected to the top of the sleeve and is connected to the exhaust pipe; and the bottom of the water-stop block has a water inlet hole, and the water inlet hole is connected to the inner cavity of the circular hole.

[0015] A float is disposed inside a circular hole, and the diameter of the circular hole is the same as the diameter of the circular hole.

[0016] Preferably, a rubber ring is fixedly connected to the inner wall of the perforation, and the rubber ring is elastic.

[0017] Preferably, the outer periphery of the mounting cylinder is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are equidistantly distributed on the outer periphery of the mounting cylinder.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] By sealing and fixing the sleeve to the water tank and screwing the mounting sleeve to the sleeve, a sealed detection cavity is formed. When water leaks at the interface between the water outlet pipe and the tank, the liquid level change in the sealed cavity can be detected in real time with the water level sensor. This not only allows for real-time monitoring of leakage at the interface between the water outlet pipe and the water tank, but also avoids the risk of short circuit caused by the expansion of leakage, thus improving the timeliness of the device's fault response and the safety of the equipment.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: Leakage detection device for cleaning robots, see [link / reference] Figures 1 to 5 ,include:

[0028] Water outlet pipe 11 is located at the water outlet end of the water tank 1 of the cleaning robot;

[0029] A leak detection mechanism is used to detect the sealing status of the connection between the water outlet pipe 11 and the water tank 1. The leak detection mechanism includes:

[0030] Sleeve 2 is fitted at the connection between the water outlet pipe 11 and the water tank 1, with one end of it being sealed and fixedly connected to the water tank 1.

[0031] The mounting cylinder 21 has a hollow cylindrical structure with one end open. At the bottom center away from the open end, there is a through hole 23 for the water outlet pipe 11 to pass through. The mounting cylinder 21 is coaxially sleeved on the outside of the water outlet pipe 11 through the through hole 23, and the inner wall of the mounting cylinder 21 is screwed into the outer wall of the sleeve 2 through a threaded structure.

[0032] The water level detection component 4 is located at the bottom of the inner cavity of the sleeve 2 and is used to detect the change of liquid water level in the sealed cavity between the mounting cylinder 21 and the sleeve 2. The water level detection component 4 is a water level sensor. After the signal is processed by the control processor in the prior art, the water level detection component 4 is connected to an external alarm (not shown).

[0033] During operation, a sealed detection chamber is formed by the sealing and fixing of sleeve 2 and water tank 1, and the threaded connection between mounting cylinder 21 and sleeve 2. When water leaks at the interface between water outlet pipe 11 and the tank, water accumulates in the sealed detection chamber connected to mounting cylinder 21 and sleeve 2. The water level sensor can detect the liquid level change in the sealed chamber in real time. The control processor converts the liquid level signal into an alarm command, so that the external alarm can be triggered when water leakage occurs at the interface, reminding personnel to check the equipment. This not only allows for real-time monitoring of leakage at the interface between water outlet pipe 11 and water tank 1, but also avoids the risk of short circuit caused by the expansion of leakage, improving the timeliness of the device's fault response and the safety of the equipment.

[0034] For details, see Figure 3An exhaust pipe 3 is fixedly installed on the top of the sleeve 2. The inner cavity of the exhaust pipe 3 is connected to the inner cavity of the sleeve 2. A water-stopping mechanism 31 is provided on the top of the inner cavity of the sleeve 2. The exhaust pipe 3 allows the interior of the sealed cavity to be connected to the atmosphere, avoiding the impact of air pressure fluctuations inside the sealed cavity on the detection accuracy. The water-stopping mechanism 31 can automatically block the exhaust pipe 3 when the water level rises to a dangerous threshold, preventing water leakage from spreading to other areas of the robot through the exhaust pipe 3, thus forming a leak-proof barrier.

[0035] Further, see Figure 3 — Figure 5 The water-stopping mechanism 31 includes:

[0036] A water-stop block 311 is provided with a circular hole 313 at one end, and the bottom of the inner cavity of the circular hole 313 is hemispherical. The top of the water-stop block 311 is fixedly connected to the top of the sleeve 2 and communicates with the exhaust pipe 3. A water inlet hole 312 is provided at the bottom of the water-stop block 311 and communicates with the inner cavity of the circular hole 313.

[0037] A float 314 is installed inside a circular hole 313, and the diameter of the circular hole 313 is the same as that of the float 314. When water leakage causes the liquid level to rise, the float 314 blocks the exhaust pipe 3 under the action of buoyancy. Zero leakage sealing is achieved through the precise fit between the float 314 and the circular hole 313. This purely mechanical water-stopping structure does not require additional energy to drive, has high reliability and fast response, and can prevent the leakage diffusion path at the same time as the alarm is triggered.

[0038] It is worth noting that, see Figure 2 A rubber ring 22 is fixedly connected to the inner wall of the perforation 23. The rubber ring 22 is elastic. The elastic rubber ring 22 forms a radial sealing force during the tightening of the mounting cylinder 21, filling the assembly gap between the water outlet pipe 11 and the perforation 23. This can prevent liquid from seeping out along the pipe wall and absorb the vibration generated during the operation of the robot, avoid interface fatigue damage caused by rigid contact, and extend the service life of the sealing component.

[0039] It is worth noting that, see Figure 2 The mounting cylinder 21 has multiple anti-slip grooves 24 on its outer periphery, and the multiple anti-slip grooves 24 are equidistantly distributed on the outer periphery of the mounting cylinder 21. The anti-slip grooves 24 increase the friction between the hand and the surface of the mounting cylinder 21, making it easier for the operator to apply force during installation or disassembly, and ensuring that the threaded connection reaches the designed preload.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
