DETAILED DESCRIPTION

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The present invention relates to a water outlet device, comprising a base 100 and a water outlet member 200. The water outlet device is mainly used in water spraying equipment, and the water spraying equipment can be a shoulder spray, a waist spray, a shower head, etc.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the shape of the base 100 is not limited, and the base 100 can be box-shaped, rod-shaped, etc. A first water outlet 110 is provided on the base 100. The water outlet 200 is installed on the base 100, and at least two functional flow channels 300 are provided on the water outlet 200. Two, three or more functional flow channels 300 on the water outlet 200 can be provided. Each functional flow channel 300 can spray out different water shapes. It should be noted that the water shape can be a water splash shape such as granular water and columnar water. The water outlet 200 can move on the base 100, and the movement can be rotation, translation and other movements. Each functional flow channel 300 is formed with a second water outlet 310 on the water outlet 200. When the water outlet 200 moves on the base 100, each functional flow channel 300 changes position relative to the first water outlet 110 with the water outlet 200. The second water outlet 310 corresponding to each functional flow channel 300 will switch in turn to the position opposite to the first water outlet 110, and the first water outlet 110 is connected to the functional flow channel 300 through the second water outlet 310 currently in position. The other second water outlets 310 are staggered from the first water outlet 110, so that the other second water outlets 310 are temporarily connected to the first water outlet 110. An external water supply system such as a tap, a water heater, etc. supplies water to the base 100, and the water flows into the water outlet 200, and then flows through the functional flow channel 300 currently in position with the second water outlet 310. The water forms a corresponding water shape through the functional flow channel 300 and is sprayed out from the second water outlet 310. Users can quickly select different functional flow channels 300 to spray different water shapes by changing the relative position of the water outlet 200 on the base 100 according to usage needs. Fig.12 As shown, after the water outlet device is applied to water spraying equipment such as shoulder spray, waist spray, and shower, it can be combined with the original water spraying structure on the water spraying equipment to further increase the water shape selection function of the water spraying equipment and improve the user's shower experience. The overall structure is simple, and different functional flow channels 300 are integrated on the water outlet 200, which can simplify the other flow channel structures inside the water spraying equipment, and the operation is simple and the water output is stable.

[0039] In one embodiment, if Figure 2 and Figure 4As shown, a plurality of water outlets 200 are sequentially arranged on the same rotating shaft 210. The water outlets 200 can be directly formed on the rotating shaft 210, or can be sequentially installed on the rotating shaft 210. One, two, three or more water outlets 200 can be arranged on the rotating shaft 210. Each water outlet 200 is sequentially arranged in a straight strip shape along the axial direction of the rotating shaft 210 on the rotating shaft 210. The second water outlets 310 on each water outlet 200 are sequentially distributed around the central axis of the rotating shaft 210. The water outlet 200 is installed on the base 100 through the rotating shaft 210, and each water outlet 200 rotates synchronously relative to the base 100 using the rotating shaft 210. A plurality of first water outlets 110 are provided on the base 100, and the number of the first water outlets 110 is the same as the number of the water outlets 200. The distribution position of each first water outlet 110 is consistent with the distribution position of each water outlet member 200, and the water outlet members 200 and the first water outlet 110 are matched one by one. By rotating the rotating shaft 210 or one of the water outlet members 200, each water outlet member 200 rotates synchronously relative to the base 100, thereby synchronously changing the shape of water sprayed by each water outlet member 200 through each first water outlet 110. Specifically, a handle can be provided on the base 100, and the handle is connected to the rotating shaft 210, and each water outlet member 200 is rotated by turning the handle. A motor can also be provided in the base 100, and the motor is used to drive the rotation of each water outlet member 200 through an electric control method.

[0040] Based on the above embodiments, Figure 3 , Figure 4 and Figure 5 As shown, the outer wall of the water outlet 200 is provided with a spherical surface 220. The water outlet 200 can be set to be spherical as a whole, and the outer wall of the water outlet 200 is the spherical surface 220 as a whole; or the water outlet 200 can be set to be an incomplete spherical structure, and the spherical surface 220 is in the shape of a spherical crown. Each second water outlet 310 is opened on the spherical surface 220. A protrusion 120 extends from the periphery of each first water outlet 110, and the protrusion 120 protrudes in a hollow cylindrical shape along the axial direction of the first water outlet 110 toward the side where the spherical surface 220 is located. A sealing ring 130 is provided on the inner wall of the protrusion 120, and a mounting groove can be provided on the inner wall of the protrusion 120, and the sealing ring 130 is fixed in the mounting groove. Part of the spherical surface 220 of the water outlet 200 will extend into the protruding portion 120, that is, when the water outlet 200 rotates, each second water outlet 310 can rotate along with the spherical surface 220 to extend into the protruding portion 120. The spherical surface 220 abuts against the sealing ring 130, so that the sealing ring 130 surrounds the second water outlet 310 currently aligned with the protruding portion 120, ensuring that water flows out of the second water outlet 310 and then sprays out from the first water outlet 110.

[0041] In one embodiment, if Figure 5 and Figure 6As shown, the water outlet part 200 includes a water inlet 230 and a water outlet 240. The second water outlet 310 is provided on the water outlet 240. The above-mentioned spherical surface 220 can also be arranged on the surface of the water outlet 240. The interior of the water outlet 240 defines a mounting cavity 241. The water inlet 230 is detachably mounted in the mounting cavity 241. The water inlet 230 can be mounted in the mounting cavity 241 by plugging or the like. A plurality of water inlet channels 231 are provided in the water inlet 230, and the water inlet channels 231 are connected to the second water outlet 310 in a one-to-one matching manner, and the above-mentioned functional channel 300 is formed between the water inlet channels 231 and the second water outlet 310 that are matched with each other.

[0042] Based on any of the above embodiments, Figure 3 and Figure 5 As shown, a water inlet chamber 140 is provided on the base 100. The first water outlet 110 is provided on a side wall of the water inlet chamber 140. The water outlet 200 is installed in the water inlet chamber 140, and each functional flow channel 300 is connected to the water inlet chamber 140. Water enters the water inlet chamber 140. The water in the water inlet chamber 140 can enter each functional flow channel 300, but the water can only be ejected from the functional flow channel 300 aligned with the first water outlet 110, and the water flowing into other functional flow channels 300 misaligned with the first water outlet 110 can flow back into the water inlet chamber 140, and there is no need to set a corresponding closed structure for the second water outlet 310 misaligned with the other first water outlet 110. Among them, the water inlet end of each functional flow channel 300 can be separately arranged on the water outlet 200. In this embodiment, a first water inlet 250 is provided on the water outlet 200, and the first water inlet 250 remains connected to the water inlet chamber 140. At least two functional channels 300 on the same water outlet 200 are connected to the same first water inlet 250. That is, the same first water inlet 250 can serve as the water inlet end of at least two functional channels 300. Water flows into the water outlet 200 from the first water inlet 250 in the water inlet cavity 140, and then flows into each functional channel 300, and then sprays out from the second water outlet 310 aligned with the first water outlet 110, and the water of other second water outlets 310 flows back into the water inlet cavity 140.

[0043] The shape of the water sprayed from each functional channel 300 may be determined according to the structure of the water inlet channel 231 or the structure of the second water outlet 310. That is, different water inlet parts 230 and water outlet parts 240 may be used in combination to obtain more water shape options.

[0044] For example, Figure 7 and Fig. 9 As shown, the second water outlet 310 is set to be circular or slit-shaped. When water is ejected from the second water outlet 310 in a circular shape, the water is in a columnar shape. When water is ejected from the second water outlet 310 in a slit shape, the water is in a sheet shape. By setting the second water outlet 310 in different shapes, different water shapes can be obtained.

[0045] For example, Figure 7 and Figure 8 As shown, one of the functional flow channels 300 includes a first water channel 320, a second water channel 330, a third water channel 340 and a water passage chamber 350. The first water channel 320 and the second water channel 330 are used for water inlet. One end of the third water channel 340 away from the water passage chamber 350 is a second water outlet 310. The water passage chamber 350 is in a hollow cylindrical shape. The first water channel 320 and the second water channel 330 are respectively connected to the peripheral wall of the water passage chamber 350, and the water flow direction of the first water channel 320 and the second water channel 330 to the water passage chamber 350 is oriented to the eccentric position of the water passage chamber 350. The third water channel 340 is connected to the water passage chamber 350 along the axial direction of the water passage chamber 350. A water retaining block 360 extending in the axial direction is provided at the center of the water passage chamber 350. The water retaining block 360 can be arranged in a columnar shape, and the circumferential side wall of the water retaining block 360 is spaced from the circumferential side wall of the water passage chamber 350. The first water channel 320 and the second water channel 330 can be connected to the water inlet chamber 140, and the water in the water inlet chamber 140 flows in from the first water channel 320 and the second water channel 330 respectively. The water flow of the first water channel 320 and the second water channel 330 is sprayed into the water inlet chamber 140, and then flows along the interval between the water passage chamber 350 and the water retaining block 360. The water forms a rotating water flow in the water passage chamber 350 under the action of the water retaining block 360, and then flows to the third flow channel. When the water is sprayed out from the second water outlet 310 corresponding to the third flow channel, it forms granular water.

[0046] Based on the above embodiment, one end of the first water channel 320 away from the water passage chamber 350 is opened on the outer wall of the water outlet 200. One end of the second water channel 330 away from the water passage chamber 350 is connected to another functional flow channel 300. A part of the water in the water inlet chamber 140 directly enters the first water channel 320, and a part of the water first enters other functional flow channels 300 through the first water inlet 250, and then is transported to the second flow channel. The second flow channel uses other functional flow channels 300 for water flow input, optimizes the flow channel distribution inside the water outlet 200, and can reduce the space occupied by each flow channel as much as possible, thereby reducing the volume of the water outlet 200.

[0047] In one embodiment, if Fig.10 and Fig.11As shown, it also includes a main body 400. The main body 400 is provided with a second water inlet 410, a third water outlet 420 and at least two diverter channels 430. The third water outlet 420 is communicated with one of the diverter channels 430. The base 100 is mounted on the main body 400 and is communicated with one of the diverter channels 430. A switching valve 440 is mounted on the main body 400. The switching valve 440 is used to control the second water inlet 410 to be alternately communicated with each diverter channel 430. Through the control of the switching valve 440, water can be sprayed from the third water outlet 420 through a diverter channel 430, and the other diverter channels 430 are closed. After the switching valve 440 switches its position, water is transported from another diverter channel 430 to the base 100, and the water is sprayed from the second water outlet 310 after passing through each water outlet 200. The third water outlet 420 can form a water shape different from the functional flow channel 300, and further increase the water shape selection.
