Description

Technical Field

[0001] The utility model relates to a rotation switching device and a faucet. Background Art

[0002] People are paying more and more attention to oral hygiene, and the frequency of daily mouthwashing is increasing. Therefore, compared with traditional basin faucets, consumers are gradually more inclined to choose mouthwash faucets, because the water outlets of existing basin faucets are all facing downwards and cannot be rinsed, so people can only bend over and turn their heads, or collect water to rinse their mouths. However, the mouthwash outlets of most mouthwash faucets on the market are designed to face upwards, which also leads to problems such as dust falling at the water outlet when the mouthwash function is idle, unless a mechanism is added to hide the water outlet, making the faucet structure more complicated. In addition, most mouthwash outlets are fixedly designed on the faucet or pull-out head, and the water outlet angle cannot be adjusted. In order to switch between regular water splashes and mouthwash, a switch button is often required on the faucet, affecting the appearance of the product. Summary of the invention

[0044] The utility model relates to a rotary switching mechanism, which omits conventional switching structures such as buttons or push buttons, and realizes adjusting the water outlet angle, adjusting the flow rate, optional water pause function, and switching the water path by rotating the water outlet. The switching method is novel, easy to operate, and the appearance is more concise. The mouthwash outlet is designed in the same direction as the conventional water outlet, avoiding the problems of dust and residual water when the mouthwash function is idle.

[0045] The utility model is more specific: the rotating switching mechanism mainly includes a water inlet joint, a bushing, a locking piece, a connecting seat, a sealing piece, an elastic piece, a wear-resistant ring, a water inlet body, a water outlet body, etc. The water inlet body can be rotatably installed on the top of the seat body, and the water inlet joint is fixedly installed in the water inlet body; in addition, the spherical surface of one end of the water inlet joint is pressed into the spherical groove of the connecting seat through the internal thread connection of the locking piece and the water outlet body, and then the connecting seat is pressed into the water outlet body, and the connecting seat is then radially fixedly assembled with the water outlet body through the cooperation of the protrusion and the slot; at the same time, a bushing is also arranged between the locking piece and the water inlet joint to prevent the water inlet joint from falling out, and a wear-resistant ring for adjusting the rotation feel is arranged between the water inlet body and the water outlet body; a sealing piece is also arranged between the water inlet joint and the connecting seat, and the sealing piece is always tightly attached to the spherical surface of the connecting seat under the action of the elastic piece.

Two water outlets are arranged on the spherical groove of the connecting seat at the same time, and the first water outlet is arranged concentrically with the second water outlet; a water outlet for a water channel is arranged on the spherical surface of the water inlet joint, and is on the same arc surface relative to each water outlet of the chain on the connecting seat; that is, when rotated to a certain angle, the water channel can be connected to the two water outlets respectively. By driving the water outlet to drive the connecting seat to rotate radially around the water inlet joint, in the initial position, the water passage of the water inlet joint is connected to the second water outlet of the connecting seat, and the faucet emits the first water splash; as the rotation angle of the water outlet increases, the water outlet angle (i.e., the water drop point) of the second water outlet is adjusted, and at the same time, the water passage gradually moves away from the second water outlet, resulting in a decrease in the connecting cross-section, thereby achieving the effect of regulating the flow; until the water passage completely leaves the second water outlet, the water splash is closed, and the faucet enters the water pause state; as the water outlet is lifted upward, the water passage is connected to the first water outlet, and the faucet starts to emit the first water splash; at this time, the water outlet continues to be lifted upward, so that the water outlet angle of the first water splash can be adjusted, and the limiting ribs of the direct connecting seat abut against the limiting ribs of the water inlet joint. Note that the water pause state during the rotation process is optional. In other embodiments, it can be a small flow state to remind the user that the faucet handle needs to be closed in this state.
