Material and method for manufacturing waterway controller

Abstract

The utility model provides a cleaning device. The cleaning device comprises a water path controller and a capture assembly, wherein the water path controller forms a water flow passage, the capture assembly forms a first water inlet, the first water inlet is communicated with the water flow passage and the water path controller comprises an opening and closing part; when difference between external pressure and internal pressure applied to the opening and closing part is not smaller than a first preset value, the opening and closing part of the water path controller is closed to enable the water flow passage of the water path controller to be blocked; when the difference between the internal pressure and the external pressure applied to the opening and closing part is not smaller than a second preset value, the opening and closing part of the water path controller is opened to allow water to flow in the water flow passage of the water path controller; when the difference between the internal pressure and the external pressure applied to the opening and closing part is between the first preset value and the second preset value, the opening and closing part of the water path controller is kept in a natural state; the water path controller and a horizontal plane form an angle alpha and the magnitude of the angle alpha is 25-30 degrees.

Description

technical field [0001] The invention relates to a cleaner, in particular to a material and method for manufacturing a waterway controller of a cleaning device of the cleaner. Background technique [0002] Along with improving constantly of people's living standard, more and more people begin to like various wading sports such as swimming, rafting, surfing and boating. However, many wading sports places, such as swimming pools, will appear at the bottom of the pool after being used for a period of time, which will affect the quality of the pool water and the use experience, and even threaten human health seriously. Therefore, these wading sports places need to be cleaned and maintained after being used for a period of time. [0003] For wading sports places, such as swimming pools, manpower and cleaning equipment can be used for cleaning. Large objects or small and small items, such as stones, can be salvaged manually. But some dirt will be difficult to clean by manpower. ...

AI Technical Summary

Problems solved by technology

First of all, this type of waterway controller is mostly made of PP, TPR, TPE and other thermoplastic materials, which are prone to deformation when the ambient temperature is too high

The cleaning device is mostly used when the weather is hot in summer and generally needs to work continuously in the water for a long time. The long-term high-temperature and high-humidity environment causes the waterway controller to be prone to loss and aging and has a short service life.

Due to the above reasons, the service life of the existing waterway controller is generally not higher than 500 hours. Once it is used for more than 500 hours, the waterway controller will be deformed, damaged or broken due to the fatigue of the material. aging phenomenon

Secondly, the tensile performance of the existing waterway controller is relatively poor, and the waterway controller needs to be opened and closed repeatedly during use, so that the stress-bearing parts of the waterway controller are prone to cracking

Again, the existing waterway controller needs to be equipped with a high-power water pump of about 450 watts to start and operate the cleaning device to work, resulting in restrictions on the application of the cleaning device and inconvenience in use

In addition, the power of water pumps given to buyers by manufacturers of portable swimming pools is generally lower than 450 watts, but many existing cleaning devices require water pumps of more than 450 watts to drive, resulting in the disposal of the gifted water pumps.

Finally, this kind of traditional waterway controller generally requires a pump with a relatively high flow rate (such as a flow rate of not less than 4.5 cubic meters per hour) and a head (such as a head of not less than 3 meters) to start, with a large working power and high energy consumption.
