Description

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to Chinese Patent Application No. 202020715653.9 filed on May 6, 2020, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present invention relates to a sprayer face cap rotatably installed at a head part of a garden water gun and configured to switch sprayed water types, and more particularly, to a novel flexible spray nozzle sprayer face cap.

RELATED ART

At present, sprayed water types of garden water guns, such as a spray type, a linear type or a water bloom type, are switched by rotating a sprayer face cap installed at a head part of a garden water gun. The sprayer face cap is generally composed of structures such as a water division plate, a spray seat, and a main body sequentially fixed in a coaxial way. A plurality of water division holes are formed in the water division plate, a plurality of water passing structures are disposed on the spray seat, and a plurality of water outlet structures are disposed on the main body. Additionally, the plurality of water division holes are respectively communicated with the plurality of water passing structures in a one-to-one correspondence way, and the plurality of water passing structures are then respectively communicated with the plurality of water outlet structures in a one-to-one correspondence way. At the same time, one of the water outlet structures is formed by a plurality of water outlet small holes. The plurality of water outlet small holes are annularly and densely distributed in an outer end surface of the main body, so that when the sprayer face cap rotates and is switched to spray out water by the plurality of water outlet small holes, water sprayed in a sprinkling type can be formed for a user to use. However, garden water may be mixed with some fine sandy impurities, the particle size of these impurities is small, but the hole diameters of the water outlet small holes are often made smaller to ensure a longer spray range, so the water outlet small holes can be easily blocked by the fine sandy impurities, and the normal water outlet of the water outlet small holes is influenced. The water outlet small holes are directly designed on the main body made of hard plastics, so they are very difficult to clean even if they are blocked by the fine sandy impurities. Finally, the use quality of the whole sprayer face cap is reduced.

That is, the water passing cavity 22 is simultaneously communicated with the group of water outlet posts 43. Additionally, six sealing caps 12 corresponding to the water outlet posts 43 in positions are disposed on an outer end surface of the water division plate 1 relative to the spray seat 2. Each of the sealing caps covers an inner end of the corresponding water outlet post 43 in a sealed way, so that each of the water outlet posts 43 can form an independent water supply passage.

The plurality of flexible spray nozzles 6 are simultaneously formed on the flexible ring 61 in a connected way, and are simultaneously communicated with the outer ring cavity 96.

Therefore, one of the side holes 42 can be jointly communicated with the flexible spray nozzles 6 in the plurality of water outlet small holes 91 through the outer ring cavity 96. That is, one of the water division holes 11 in the water division plate 1 is supplied with water and is communicated with the corresponding side hole 42 on the spray seat 2, and then is communicated with the corresponding outer ring cavity 96 through this side hole. Therefore, the plurality of water outlet small holes 91 are simultaneously communicated. The water can be sprayed out from the flexible spray nozzle 6 in each of the water outlet small holes.
