Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an attachment for a toothpaste faucet, which can adjust the amount of water to the toothpaste faucet.

(Prior Art) In recent years, tools such as toothpaste faucets are sometimes used as tools for simultaneously brushing teeth or rinsing the mouth. This toothpaste faucet is usually attached to the faucet of a faucet such as a toilet and used while flowing water.

(Problems to be solved by the invention) However, in the conventional case, the water faucet whose water spouting amount cannot be adjusted, that is, the spouting water amount is preset to a fixed amount, and only the water supply or the water stop is switched by the water fab knob. In the case of the type, there was a problem that the amount of water sent to the toothpaste faucet was always fixed and the amount of water could not be adjusted.
Further, even in a faucet having a water amount adjusting function, there is a problem that the adjustment range becomes rough because a fine adjustment cannot be made by operating the faucet knob.

(Means for Solving the Problem) In order to solve the problem, the present invention provides an attachment which is attached to a faucet and which allows a toothpaste faucet to be freely attached and detached, and a branch water channel is branched from a main water channel of the attachment. An opening / closing valve was provided in the branch water passage, and the opening / closing valve was configured to be opened / closed by attaching / detaching a toothpaste faucet. Further, the main water channel was provided with a flow rate adjusting member downstream of the branch point with the branch water channel, so that the water flow rate could be adjusted. Further, the flow rate adjusting member is provided with a flow passage so that a small amount of water can pass even when the main water passage is closed by the flow passage.

(Function) The water supplied from the faucet flows from the main canal into the branch canal and is sent to the toothpaste through the opening / closing valve opened by the attachment of the toothpaste. At this time, if the flow rate adjusting member downstream of the branch point adjusts the flow rate of the main water channel, the water flow rate to the branch water channel is inevitably adjusted. Even if the opening / closing valve is closed by removing the toothpaste faucet and the faucet knob is opened while the flow rate adjusting member is also in the closed position, the water slightly flows out from the flow passage of the flow regulating member. However, problems due to high water pressure in the attachment, such as damage to the faucet valve due to reverse pressure, do not occur.

An insertion hole 16 is provided at a position between the communication hole 14 and the water discharge port 13 in a direction orthogonal to the communication hole 14, and the insertion hole 16 is a sectional view taken along the line BB of FIG. 4-A. As shown in Fig. B, a groove for 0-ring fitting is provided at a position slightly separated from the main waterway 11.
16a is provided.

Ball catch body attached to the aforementioned recessed screw part 15
As shown in FIG. 5, 20 is provided with a threaded portion 21 on the outer circumference on one end side, and a through hole provided in the central axis is configured as a branch water passage 22.

An opening / closing valve 23 is incorporated in the branch water passage 22, and the water passage is opened / closed by removing the tip of the hose 51 of the toothpaste plug inserted from the protruding end side. That is, the opening / closing valve 23 is a ball portion that is biased forward by the spring 24.
The bush 26, which is provided with the ball portion 25 and is pushed forward by the ball portion 25, shuts off the water passage when the tip of the hose portion 51 is pulled out, and opens the water passage when pushed by the inserted hose. Further, 0-rings are fitted in front of and behind the bush 26 to maintain watertightness.

On the other hand, as shown in FIG. 6, the spindle body 30 as a flow rate adjusting member is provided with a shaft portion 31 inserted into the above-mentioned insertion hole 16, and the diameter of this shaft portion 31 is larger than the inner diameter of the main water passage 11. It is installed so as to block the waterway. Shaft facing this main waterway 11
As shown in FIG. C, which is a partial view from the Z direction of FIG. A, a substantially semicircular portion is cut out and formed as a cutout portion 32 in 31. Further, a small hole 33 as a flow passage is provided and penetrates from the bottom surface of the notch 32 toward the outer peripheral surface on the opposite side.

An engaging portion having a notch on the outer periphery on one end side of the shaft portion 31.
