Description

Technical Field

[0001] This utility model relates to the field of swimming pool cleaning machine technology, specifically to a swimming pool cleaning machine wall contact detection device and a swimming pool cleaning machine. Background Technology

[0002] Many swimming pool owners consider using automated equipment to maintain water cleanliness. Among various types of equipment, pool cleaning machines are a common choice. These machines are primarily used to clean debris from the pool bottom and walls, reducing the need for manual operation. They differ from other cleaning methods in several ways.

[0003] Existing pool cleaning machines often use ultrasonic and infrared technologies for wall contact detection. However, ultrasonic wall contact detection has drawbacks: ultrasonic waves are easily absorbed in water, and the sound wave energy attenuates rapidly, affecting measurement accuracy. Infrared wall contact detection suffers from the disadvantage that infrared sensors are sensitive to ambient light, temperature, and humidity. Sunlight above the pool can interfere with the sensor signal, leading to decreased measurement accuracy. Based on these considerations, we propose a wall contact detection device and a pool cleaning machine. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems in the prior art and provide a wall contact detection device and a pool cleaning machine. This wall contact detection method is more accurate than the wall contact detection methods using ultrasonic and infrared technologies.

[0005] To solve the above-mentioned technical problems, this utility model proposes a wall contact detection device for a swimming pool cleaning machine, including a moving part, a fixed part and a spring. The moving part includes a magnet mounting block and a magnet, with the magnet installed inside the magnet mounting block.

[0006] The fixing part includes a sensor mounting block and a Hall sensor. The Hall sensor is installed inside the sensor mounting block, and a spring connects the magnet mounting block and the sensor mounting block.

[0007] Preferably, a cylinder one is provided on one side of the sensor mounting block, a cylinder two is provided in the magnet mounting block, and a spring is sleeved on cylinder one and cylinder two.

[0008] Based on the above technical features, this helps the spring to be compressed in a straight line.

[0009] Preferably, one end of the cylinder is provided with a fitting groove for mounting and cooperating with the magnet, and the other end of the cylinder is an integral structure with the magnet mounting block.

[0010] Based on the above technical features, the deep groove facilitates the fitting and installation of the magnet inside the magnet mounting block.

[0011] Preferably, a retaining ring is provided on the outer side of the end of the magnet mounting block that is close to the fixing part.

[0012] Based on the above technical features, this prevents the moving parts from detaching from the side wall of the fuselage.

[0013] Pool cleaning machine, including the aforementioned pool cleaning machine's wall contact detection device.

[0014] A pool cleaning machine, including the machine body, with a wall contact detection device installed on the front or rear side of the machine body.

[0015] The pool cleaning machine includes a body. The wall contact detection device of the pool cleaning machine is installed on the front or rear side of the body. The front or rear side of the body has a through hole that matches the magnet mounting block. The inner diameter of the through hole is smaller than the outer diameter of the retaining ring. The retaining ring is located inside the body. This facilitates the guidance of the extension and retraction of the magnet mounting block and prevents the moving part from falling off the body.

[0016] In summary, this utility model has at least one of the following beneficial effects:

[0017] When the pool cleaner touches the wall, the magnet mounting block is pushed against the wall, the spring contracts, and the magnet mounting block moves towards the sensor mounting block. The magnet approaches the Hall sensor, and the Hall sensor detects the magnet's proximity, indicating that the pool cleaner has touched the wall. This method of wall contact detection is more accurate than that using ultrasonic and infrared technologies. Attached Figure Description

[0030] A cylinder 403 is provided on one side of the sensor mounting block 401, and a cylinder 304 is provided in the magnet mounting block 301. The spring 5 is sleeved on the cylinder 403 and the cylinder 304, which helps the spring 5 to be compressed in a straight line.

[0031] One end of the cylinder 304 is provided with a fitting groove for mounting and cooperating with the magnet 302. The fitting groove facilitates the fitting and installation of the magnet 302 in the magnet mounting block 301. The other end of the cylinder 304 and the magnet mounting block 301 are an integral structure.

[0032] A retaining ring 303 is provided on the outer side of one end of the magnet mounting block 301 that is close to the fixing part 4. The retaining ring 303 is located in the body 1, which prevents the moving part 3 from falling off the side wall of the body 1.

[0034] The pool cleaning machine includes a body 1. The wall contact detection device of the pool cleaning machine is installed on the front or rear side of the body 1. The front or rear side of the body 1 has a through hole 101 that cooperates with the magnet mounting block 301. The inner diameter of the through hole 101 is smaller than the outer diameter of the retaining ring 303. The retaining ring 303 is located inside the body 1, which facilitates the guidance of the extension and retraction of the magnet mounting block 301 and prevents the moving part 3 from falling off the body 1.

[0035] The Hall sensor 402 is existing technology and is a mature technology mastered by those skilled in the art. In this embodiment, it is only used without changing its structure and function, and can be purchased directly from the market.

[0036] Working principle:

[0037] When the pool cleaner touches the wall, the magnet mounting block 301 is pushed against the wall, the spring 5 contracts, and the magnet mounting block 301 moves toward the sensor mounting block 401. The magnet 302 inside the magnet mounting block 301 approaches the Hall sensor 402 in the sensor mounting block 401. The Hall sensor 402 detects the approach of the magnet 302 and concludes that the pool cleaner has touched the wall. This method of wall contact detection is more accurate than the wall contact detection methods using ultrasonic and infrared technologies.
