Now every family has a car, but cleaning the car is very troublesome. Every time we go to the car wash shop, we have to wait a long time. It is more convenient to buy a household high-pressure water gun and do it yourself. Today, I’ll teach you some buying skills for washing water guns
1. faucet connector
This is the most noteworthy issue for buyers. After a friend buys a water gun for car washing and takes it home, he will be unable to use it because the faucet connector and the faucet at home are not matched. In fact, at present, the faucet connector generally has screw type, fixed caliber type and universal type. Thread type designed for faucets with threads; Rubber faucets with fixed caliber are mostly 4mm, and rarely 6mm. In other words, a 4mm faucet connector can only connect to a 4mm faucet, and a 6mm faucet can only connect to a 6mm faucet.Universal faucet is a new type of faucet that has emerged recently. It can basically connect the above faucets.
2. water pipe joint
There are two types of water pipe joints: connected and removable. The integral connector and water pipe are connected with the water pipe when leaving the factory. It is troublesome if it breaks down, so we are not recommended to buy it; Then there is the detachable water pipe union, which is generally of the spring bayonet type, and is also divided into two types: water connected and water stop. Among them, water is the most common, and there is another kind that can stop water, which is generally used to connect to the end of the water gun. Its biggest advantage is that if you want to change a water gun or a water brush when you work, when you remove the connector of the water gun, the baffle inside will automatically turn off the water source under the thrust of the water flow, eliminating the trouble of turning off the faucet;
3. water pipe
Water pipes are the important components, which are generally divided into two categories: braided pipes and plastic pipes. As the name suggests, the braided pipe is generally made of nylon. Its main advantage is that it is cheap, but its disadvantage is that it has a short service life and is easy to leak; Generally, rubber is used as the main material for plastic pipes, which is relatively durable and not prone to water leakage, but there are also advantages and disadvantages. The quality of the pipes mainly depends on the smell, gloss, elasticity and the density of the middle screen;
4. water gun
There are many kinds of water guns with different quality. Generally speaking, there are the following types according to the material: zinc alloy copper head gun, plastic copper core gun, plastic galvanized gun and all plastic gun. The zinc alloy gun with good quality should be made of zinc alloy, wrapped with good plastic outside, and held with good PP plastic. The gun made of this method will never rust, is not easy to damage, has a long service life, and feels comfortable to hold. If we compare the quality of the above guns, zinc alloy gun is the best, plastic copper core gun is the second, and plastic gun is average. It is worth mentioning that the copper color of a good zinc alloy copper gun should be bright, not dark, not black. This is the high purity of copper.
