Patent Description:
At present, to change the water outlet manner of a faucet, a water outlet device is generally arranged under the faucet to control or regulate the outlet flow and outlet state of the faucet.

To keep the outer diameter of the water outer device consistent with the outer diameter of the faucet, the applicant has applied for the following patents:
A water outlet control device (Authorized Publication No.<CIT>) discloses a water diversion body and a water guide body, wherein the water diversion body comprises a guide hole penetrating through the water diversion body; the water guide body comprises a first water inlet, a second water inlet, a first water outlet channel and a second water outlet channel, the first water inlet is communicated with an upper space of the second water inlet and is communicated with the first water outlet channel and the second water outlet channel, the second water inlet is communicated with the first water outlet channel, and a water outlet of the first water outlet channel surrounds a water outlet of the second water outlet channel; the water diversion body is rotatably connected to the water guide body, the guide hole is communicated with the first water inlet or the second water inlet when the water diversion body rotates with respect to the water guide body, and the upper space is defined by the water outlet end of the guide hole and the space between the first water inlet and the second water inlet.

In the above patent, the guide hole is switched to the first water inlet or the second water inlet through the planar rotation of the water diversion body with respect to the water guide body, and the first water outlet channel and the second water outlet channel of the water guide body respectively discharge one type of functional water, so the water outlet control device in this patent can realize the switching of two types of functional water.

The water outlet control device in this patent is small in size, but it can discharge only two types of functional water and thus cannot satisfy more requirements of users.

<CIT> discloses a water tap assembly comprising three different ports connectable each to a respective water supply line, and a control valve that selects whether mixed-water is discharged to a water discharge head of the water tap assembly. The discharge head includes a diverter which selects whether the mixed-water is to be outletted as an aerated stream or a spray.

There are devices that can discharge multiple types of functional water on the present market such as showers. Existing showers typically have three different water outlet manners and realize switching of multiple water passages by means of planar rotation of parts. During actual research and development, to make the showers small enough to be applied to faucets, the outer diameter of the showers can only be reduced to <NUM>, which mismatches the size of the faucets. Thus, it will be a great challenge to realize switching of multiple types of functional water within a limited space.

The technical issue to be settled by the invention is to provide a water outlet device to solve the problems that existing water outlet devices can discharge only a few types of functional water.

To settle the aforesaid technical issue, the technical solution adopted by the invention is as follows:.

The invention has the following beneficial effects: the diversion mechanism is arranged to realize different water outlet manners in the moving process of the guide mechanism and is additionally provided with the first water outlet channel within a limited space, so that compared with the prior art, one type of functional water is added without increasing the overall size of the water outlet device. When the water inlet channel is communicated with the first water outlet channel, a first type of functional water can be formed. When the water inlet channel is communicated with the second water outlet channel, a second type of functional water can be formed. When the water inlet channel is communicated with the third water outlet channel, a third type of functional water can be formed. These three types of functional water are suitable for different application scenarios to make it possible to use faucets or other bath products as multifunctional water outlet devices to meet daily requirements of users. Compared with the prior art, the water outlet device of the invention is simple in structure, occupies a small space, additionally realizes one type of functional water without increasing the occupied space, can switch different water outlet manners, and has higher practical value.

The technical contents, purposes and effects of the invention will be expounded below in conjunction with the implementations and accompanying drawings.

When water enters the second water outlet channel <NUM> from the transitional passage <NUM>, air is sucked in via the air inlet gap <NUM> to form aerated water.

To sum up, according to the water outlet deice provided by the invention, the diversion body, the barrier and the protrusions are matched with the steps to shift three gears to realize switching of different water outlet channels to obtain three different types of functional water. The linking process is simple, switching of three different types of water can be realized by means of rotation, so that operation is easy, the water outlet manners of the bathroom water outlet products are enriched, different using requirements of users are met; and by arranging the diversion body, one type of functional water, namely water mist or blade water, is added without increasing the space to wash objects with the surface stained by stubborn dirt.

Claim 1:
A water outlet device, comprising a water inlet mechanism (<NUM>), a diversion mechanism (<NUM>), and a guide mechanism (<NUM>) rotatably connected to the water inlet mechanism (<NUM>), wherein:
the diversion mechanism (<NUM>) is disposed in the water inlet mechanism (<NUM>) and penetrates coaxially through the guide mechanism (<NUM>);
the water inlet mechanism (<NUM>) comprises a water inlet channel (<NUM>);
the diversion mechanism (<NUM>) comprises a first water outlet channel (<NUM>);
the guide mechanism (<NUM>) comprises a second water outlet channel (<NUM>) and a third water outlet channel (<NUM>);
when the guide mechanism (<NUM>) moves with respect to the diversion mechanism (<NUM>), the water inlet channel (<NUM>) is communicated with the first water outlet channel (<NUM>), the second water outlet channel (<NUM>) or the third water outlet channel (<NUM>);
said water outlet device being characterized in that the diversion mechanism (<NUM>) comprises a diversion body (<NUM>) and a reset member (<NUM>); wherein a functional part (<NUM>) is disposed in the diversion body (<NUM>) and is suitable to form flow patterns of a flow of water; and in that one end of the reset member (<NUM>) abuts against the functional part (<NUM>), and another end of the reset member (<NUM>) abuts against one side of the water inlet mechanism (<NUM>).
