The arrangement, angle, number and aperture of the water nozzles will also directly affect the water outlet experience of the shower. Because the internal structure is invisible, the arrangement of the water nozzles cannot be quantitatively evaluated. Here we focus on the aperture and number of the water nozzles.
Number of water nozzles: Under the same shower head diameter, if the number of water nozzles is too small, although the pressure can be better, the cleaning area is small or the water column is prone to hollow in a large range, which affects the cleaning effect of the shower. If there are many water outlet holes, or the design of the water outlet holes is very small, such as less than 0.3, otherwise it is easy to have weak water outlet, which will also affect the cleaning effect. In addition, if the water outlet is less than 0.3MM, it can only be directly covered with the opening, which is difficult to design as a soft glue nozzle. In this case, the water quality is too hard and it is easy to cause the water nozzle to be blocked, and cleaning is troublesome. Therefore, the number and arrangement angle of the water nozzles need to be reasonably designed in combination with the diameter of the cover to ensure that the water outlet area is sufficient and the water outlet strength is good.
Outlet aperture: At present, the mainstream apertures on the market can be divided into three types
1. The apertures of the water outlet are all above 1.0MM. For example, Hansgrohe’s Raindance and Rainstorm will spray a larger amount of water. When the water pressure at the home is relatively high, the water from the shower with poor structural design will be heavy and some will feel tingling. In this state, the bathing experience will be very bad, especially if the skin is relatively delicate Children will feel uncomfortable, but the well-designed shower is full of water, and the cleaning and wrapping is in place. It is very easy to use for friends who like high-flow showers; but when the water pressure at the home is small, the shower with a large aperture will emit water. It is relatively soft and weak, the spray distance is short, and the shower experience is very general. The advantages of this type of soft glue nozzle with a larger aperture: it is relatively easy to block, if there is a blockage, the soft glue nozzle can generally be solved by rubbing it. The disadvantage is that the water outlet aperture is relatively large, the water outlet will be relatively weak and use a lot of water; and the number of water outlet holes arranged on the shower surface of the same diameter is relatively small, in this case, the coverage of the cleaning spray density will be sparse, and sometimes the cleaning efficiency It will be slower and more water-intensive.
2. Ultra-fine hard-hole faucets with a diameter of 0.3MM or less: showers with such diameters can be defined as ultra-fine sprays. The following Japanese-style ultra-fine showers and ultra-fine showers with stainless steel cover are common, with average apertures. At 0.3MM, the water outlet holes are extremely fine, which can play a good supercharging effect and can better solve the problem of low water pressure. However, the shortcomings of this type of shower are also obvious. The extremely fine hard-hole nozzles are easy to block, especially in areas with relatively hard water quality in China, such as the north, under normal use, one-third of the water nozzles may be blocked within a month (measured use ), it is very inconvenient to clean up after it is blocked. The advantage of this type of shower head is that the water outlet aperture is relatively small, and the shower head with the same diameter will have more water outlet holes. In the case of many water outlet columns, the cleaning coverage density will be higher, and the cleaning efficiency will be higher while saving water and pressurizing. high.
3. The diameter of the water nozzle is 0.4-0.5MM soft glue nozzle: this type of aperture shower can be defined as a fine spray, which is basically a shower newly developed in recent years. The big spray is much thinner, which can have a good supercharging effect. At the same time, the faucet is made of silica gel, and the aperture is relatively large (compared to the 0.3MM ultra-fine spray), which is not easy to block the hole and is easy to clean. It can be solved. This type of shower is the mainstream type of shower at present, and the water output effect is generally not bad. However, to design a shower that has both good pressure and a soft water discharge experience, it requires R&D personnel to have excellent design capabilities and rich practical design experience, and also requires a bit of luck.
