Air injection booster handheld shower head

Abstract

An air injection booster handheld shower head comprises a casing, a hollow handle, a Venturi tube and a water discharge assembly, wherein the water discharge assembly is arranged in a lower opening of the casing; the casing is formed integrally with the handle; a main body is provided with an axial air guide slot; the air guide slot ranges from the water intake interface end of the main body to an air intake hole, and is communicated with the air intake hole; and the air guide slot and the inner wall of the opening end of the handle form an air guide water channel. The air injection booster handheld shower head also comprises a water guide tube, wherein one end of the water guide tube is connected with a water discharge interface of the Venturi tube, and the other end is communicated with the hollow cavity between the top plate of the casing and the water discharge assembly.(A) Water introduces air when flowing through the Venturi tube, and the air is mixed fully with the water to form bubble water.(B) The air attracting capability of the shower head is improved greatly; and even if the multifunctional shower head switches gears, the water keeps flow speed unchanged and is injected along the water guide tube directly into the panel of the shower head to increase water discharge pressure. Therefore, water cannot flow out from air attracting holes even if the water discharge amount is decreased or increased, so as to really achieve the effect of air injection boosting.

Description

technical field [0001] The invention relates to a shower head for showering, in particular to a portable shower head. Background technique [0002] At present, there is an air-injected pressurized portable shower, which includes a housing, a hollow handle, a Venturi tube, a water guide pipe and a water outlet assembly arranged in the housing. The housing and the handle are integrally formed, and the Venturi tube Set at the end of the handle; one end of the Venturi tube communicates with the water source, and the other end communicates with the cavity between the top plate of the housing and the water outlet assembly; the Venturi tube includes a body, a water inlet interface and a water outlet interface, and the body There is an air inlet hole along the radial direction, and there are positioning ribs along the axial direction on the outer peripheral surface; there is a positioning groove on the inner wall of the opening end of the handle, and the positioning rib cooperates w...

AI Technical Summary

Problems solved by technology

The problem is: the air-injected pressurized hand showers on the market are only limited to the hand showers with relatively small water output. The Venturi principle is also applied to the hand showers larger than 4 inches (including 4 inches). (Including 4 inches) the handle chamber of the large portable shower has a large volume. When the water flows through the chamber, the water flow speed is greatly slowed down, which reduces the water outlet pressure of the shower. At the same time, the suction capacity of the shower is greatly reduced. Reduced air injection boost effect

When the multi-functional shower is switched to spray or massage water or bubble water, the water will flow back from the suction hole due to the reduced water output, and the effect of air injection and pressurization will not be formed.
