Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a two-handed nozzle that can be held with both hands and used by switching the flow of liquid between a straight flow and a swirling flow.

[Conventional technology]

A conventional two-handed nozzle of this type will be explained with reference to FIG. In the figure, 1 is a nozzle chip that has a liquid spout 1a in the center, and 2 is a nozzle chip 1.
A tip holder 3 holds the tip holder 2; 3 is a spouting tube to which the tip holder 2 is screwed; 4 is a partition plate pressed against the tip surface of the spouting tube 3 and held by the tip holder 2; 5 is a partition plate 4 and a liquid spout 1a; A liquid swirling chamber is formed between the nozzle tip 1 and the tip holder 3. 6
7 is the center hole provided in the center of the partition plate 4, and 7 is the center hole 6.
A plurality of pivot holes are arranged in the partition plate 4 so as to be located on the outer circumference of the center hole 6, and have a certain angle with the central axis of the center hole 6. Reference numeral 8 denotes a rod inserted into the ejection pipe 3, and is screwed onto the base end wall 3a of the ejection pipe 3.
Reference numeral 9 denotes an operating handle for the rod 8, and by turning this, the rod 8 moves forward and backward. 10 is one handle provided on the proximal end side of the jet pipe 3; 11 is a liquid feeding port provided on one handle 10; 12 is a liquid feeding port 11
A lever 13 for switching between sending and stopping the liquid sent into the ejection pipe 3 is the other handle provided at the middle part of the ejection pipe 3.

Next, the operation will be explained. Both handles 10, 13
When grasping with both hands and pulling the lever 12, the ejection pipe 3
The liquid sent inside passes through the swirling chamber 5 as a straight flow from the center hole 6, and is ejected as a straight flow from the liquid jet port 1a. Then, when the operation handle 9 is turned to close the center hole 6 with the tip of the rod 8, the ejection pipe 3
The liquid inside swirls in the swirling chamber 5 as a swirling flow from the swirling hole 7, and then jets out as a swirling flow from the liquid spouting port 1a.

[The problem that the idea aims to solve]

In the conventional two-handed nozzle as described above, the operating handle 9 must be turned to switch the jet flow between the straight flow and the swirling flow, so each time the switch is made, one of the handles 10 and 13 must be released. However, there were problems in that switching operability was poor and cleaning workability was also poor. In particular, poor switching operability is a major problem in cleaning operations such as those for automobiles, machinery, etc., in which it is necessary to frequently switch the jet flow between a straight flow and a swirling flow.

This idea was made in order to solve this problem, and the jet flow can be switched between a straight flow and a swirling flow while holding both handles without taking your hands off the handles. The purpose is to obtain a hand-held nozzle.

[Means to solve the problem]

The two-handed nozzle according to this invention includes a nozzle chip having a liquid jetting port in the center, a jetting tube having this nozzle chip at the tip and feeding liquid from the base end side,
One handle provided on the proximal end side of the ejection tube, a partition provided in front of the nozzle tip, a liquid swirling chamber formed between the partition and the liquid ejection port, and a center provided in the center of the partition. a hole, a plurality of turning holes arranged on the partition wall so as to be located on the outer circumference of the central hole and having a certain angle with the central axis of the central hole, a passage switching hole provided in the middle of the jet pipe; a valve, a proximal end communicating with the passage switching valve, and a distal opening having an inner ejection pipe fitted into the center hole, and an operation handle of the passage switching valve protruding to the outside of the ejection pipe and serving as the other handle. When the inner jet pipe is communicated with the passage switching valve, the liquid on the base end side of the jet pipe enters the inner jet pipe from the passage switching valve and passes through the swirling chamber as a straight flow from the center hole. The liquid is ejected from the liquid ejection port as a straight flow, and when the inside of the ejection pipe around the inner ejection pipe is communicated by the passage switching valve, the liquid on the proximal end side of the ejection pipe flows from the passage switching valve to the The liquid enters the jetting pipe around the inner jetting pipe, swirls in the swirling chamber as a swirling flow from the swirling hole, and then jets out as a swirling flow from the liquid jetting port.

[Effect]

In this invention, since the other handle also serves as the operating handle of the passage switching valve, the jet flow can be switched between the straight flow and the swirling flow by operating the other handle. Therefore, the jet flow can be changed while holding both handles without removing hands from both handles.

[Example of idea]

An embodiment of this invention will be described with reference to FIGS. 1 to 5. Figure 1 is an overall side view, Figure 2 is a vertical side view of the main parts, Figure 3 is a sectional view taken along the line in Figure 2, Figure 4 is a sectional view taken along the line in Figure 2, and Figure 5 is a sectional view taken along the line in Figure 2. The figure corresponds to FIG. 4 showing a state in which the flow has been switched to a swirling flow, and the same or corresponding parts as those in the conventional system are given the same reference numerals and the explanation thereof will be omitted. In the figure, 14 is a partition formed at the base end of the tip holder 2, and has a center hole 6 and a pivot hole 7. Reference numeral 15 denotes a passage switching valve provided in the middle part of the ejection pipe 3, which includes a cylindrical body 15a fixed to the ejection pipe 3 and a rotor 15b rotatably inserted into the cylindrical body 15a.
The rotor 15b and the cylindrical body 15a are penetrated by a straight flow passage 15c, and the straight flow passage 15c is formed at an angle with respect to the rotational direction. 1
Reference numeral 6 denotes an inner jet pipe fixed to the outer circumferential surface of the cylindrical body 15a so that its base end communicates with the straight flow passage 15c, and whose distal end is fitted into the center hole 6; 17 is an operating handle of the rotor 15b; It also serves as a handle. In addition, 18 in the figure is a nozzle tip cover.

In the states shown in FIGS. 1 to 4, the operating handle 17 is in the front (on the right side in the figure), so the passage switching valve 1
The inner jet pipe 16 is connected to the straight flow passage 15c of
The liquid sent into the jet pipe 3 enters the inner jet pipe 16 from the straight flow path 15c, passes through the swirling chamber 5 as a straight flow from the center hole 6, and flows straight through the liquid jet port 1a as a straight flow. gush. When the operating handle 17 is pushed forward (to the left in the figure), the rotor 15b rotates, and as shown in FIG. The liquid enters the jet pipe 3 around the inner jet pipe 16 from the swirl flow passage 15d, swirls in the swirl chamber 5 as a swirl flow from the swirl hole 7, and then jets out as a swirl flow from the liquid jet port 1a.

In this manner, by gripping and operating the operating handle 17 which also serves as the other handle, the ejected flow can be switched between a straight flow and a swirling flow. Therefore, the ejection flow can be changed while holding the handles 10 and 17 without removing the hands from the handles 10 and 17.

[Effect of idea]

As described above, according to this invention, it is possible to switch the jet flow between the straight flow and the swirling flow while holding both handles without taking your hands off the handles, and therefore the jet flow can be easily switched. This has the effect of improving cleaning workability.
