Claims

[Claims for Utility Model Registration] A nozzle chip having a liquid spout in the center, a jet pipe having the nozzle chip at the tip and feeding liquid from the base end, one handle provided on the base end of the jet pipe, A partition wall provided in front of the nozzle tip, a liquid swirling chamber formed between the partition wall and the liquid jet port, a center hole provided in the center of the partition wall, and a partition wall located on the outer circumference of the center hole. A plurality of swirl holes are arranged in the partition wall and have a certain angle with the center axis of the center hole, a passage switching valve is provided in the middle part of the jet pipe, and a proximal opening communicates with the passage switching valve and the tip The end port includes an inner ejection pipe that is fitted into the center hole, and an operation handle for the passage switching valve that protrudes outside the ejection pipe and also serves as the other handle, and the inner ejection pipe is communicated with the passage switching valve. Then, the liquid on the proximal end side of the ejection pipe enters the inner ejection pipe from the passage switching valve, passes through the swirling chamber as a straight flow from the center hole, and is ejected as a straight flow from the liquid jet port, and When the inside of the jet pipe around the inner jet pipe is communicated with the passage switching valve, the liquid on the proximal end side of the jet pipe enters the jet pipe around the inner jet pipe from the passage switching valve and passes through the swirl hole. A two-handed nozzle, characterized in that the liquid swirls in the swirling chamber as a swirling flow and then is ejected from the liquid jetting port as a swirling flow.
