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.

[0029] The present invention relates to a water outlet device, comprising a water outlet mechanism 100 and a driving assembly 200 .

[0030] As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the water outlet mechanism 100 includes at least two water rings 110, and the water rings 110 are sequentially arranged from the inside to the outside. The number of water rings 110 can be two, three, four or more. Two adjacent water rings 110 can move relative to each other in the axial direction. A plurality of water channels 120 are defined between adjacent water rings 110. One end of each water channel 120 serves as a water inlet end 122, and the other end serves as a water outlet end 121. When two water rings 110 are provided, a plurality of water channels 120 are defined between the inner wall of the water ring 110 located in the outer circle and the outer wall of the water ring 110 located in the inner circle. When the number of water rings 110 is three or more, as in the present embodiment, four water rings 110 are provided, each of which is in the shape of a hollow cylindrical ring. The four water rings 110 are defined as a first ring 111, a second ring 112, a third ring 113 and a fourth ring 114 from outside to inside, the first ring 111 has the largest inner diameter, the second ring 112 is the second, and the fourth ring 114 has the smallest inner diameter. The first ring 111 is sleeved outside the second ring 112, the inner wall of the first ring 111 and the outer wall of the second ring 112 are attached to each other and define a plurality of water channels 120 therebetween. The second ring 112 is sleeved outside the third ring 113, the inner wall of the second ring 112 and the outer wall of the third ring 113 are attached to each other and define a plurality of water channels 120 therebetween. The third ring 113 is sleeved outside the fourth ring 114, the inner wall of the third ring 113 and the outer wall of the fourth ring 114 are attached to each other and define a plurality of water channels 120 therebetween. In the direction shown in the figure, each water channel 120 is formed along the axial direction of the water ring 110. In the direction shown in the figure, the upper end of each water channel 120 is the water inlet end 122, and the lower end is the water outlet end 121. When the adjacent water rings 110 move axially relative to each other, each water channel 120 changes accordingly, and the aperture of the water outlet end 121 of each water channel 120 increases or decreases accordingly. The drive assembly 200 is used to control the axial movement between each water ring 110. Among them, the drive assembly 200 can use different shafts to control the asynchronous axial movement of each water ring 110, or it can control the synchronous axial movement of each water ring 110. It can be that when the drive assembly 200 changes the relative position of each water ring 110, each water ring 110 moves synchronously, that is, the aperture of the water outlet end 121 of each water channel 120 increases or decreases synchronously, so that the injection intensity of the formed water column increases or decreases synchronously. The water outlet device can be applied to spray guns, shower heads, etc., and the water outlet device in the present invention can be applied to water-using equipment such as faucets and shower heads. The water inlet end 122 of each water channel 120 is connected to the water inlet side of the water-using equipment. When water is passed, water flows into the water channel 120 from the water inlet end 122 of each water channel 120, and forms a water column and sprays out from the water outlet end 121 of each water channel 120. Initially, the lower end surfaces of each water ring 110 can be flush, at which time the apertures of the water outlet ends 121 of each water channel 120 are equal in size, and the water columns sprayed from each water channel 120 are of equal diameter. When adjustment is required, the water rings 110 are controlled to move relative to each other by the drive assembly 200.In this embodiment, as shown in FIG6 and FIG7, the first ring 111 is taken as a reference, the first ring 111 is relatively stationary in the axial direction, and then the second ring 112 is moved axially downward relative to the first ring 111, and the lower end surface of the second ring 112 protrudes downward from the lower end surface of the first ring 111; the third ring 113 is moved axially downward relative to the second ring 112, and the lower end surface of the third ring 113 protrudes downward from the lower end surface of the second ring 112; the fourth ring 114 is moved axially downward relative to the third ring 113, and the lower end surface of the fourth ring 114 protrudes downward from the lower end surface of the third ring 113. Adjacent water rings 110 are distributed in a stepped manner, and the water outlet 121 of the water channel 120 becomes larger after the relative axial movement. Under the condition of equal water supply, the water outlet 121 becomes larger, the sprayed water column becomes thicker, and the water spray intensity decreases. By adjusting the axial relative positions between adjacent water rings 110 through the driving assembly 200, the aperture change of the water outlet end 121 of the water channel 120 is flexibly controlled, thereby achieving stepless adjustment of the water column strength.

[0031] In some specific embodiments of the present invention, as shown in FIG. 5 and FIG. 7 , a water inlet cavity 130 is defined between each water ring 110, and the water inlet end 122 of each water channel 120 is connected to the water inlet cavity 130. In this embodiment, the first ring 111 is in a convex shape, and the first ring 111 is hollow inside and has openings at both ends. The second ring 112, the third ring 113 and the fourth ring 114 are located in the first ring 111, and a certain space is formed between the upper part of the second ring 112, the third ring 113 and the fourth ring 114 and the upper part of the first ring 111, and the space constitutes the water inlet cavity 130. The drive assembly 200 coaxially penetrates into the first ring 111 from the upper end of the first ring 111, and is connected to the second ring 112, the third ring 113 and the fourth ring 114. The upper end opening of the first ring 111 can be connected to a joint 300, and the joint 300 is used to connect to an external water supply pipe, etc. After water enters the water inlet chamber 130 , it is divided into the water channels 120 .

[0032] Wherein, a limiting structure is provided between adjacent water rings 110. The limiting structure includes a clamping protrusion 401 and a clamping groove 402, wherein the clamping groove 402 is provided on one of the two adjacent water rings 110, and the clamping protrusion 401 is provided on the other. The clamping protrusion 401 and the clamping groove 402 extend along the axial direction of the water ring 110. In this embodiment, as shown in FIG. 2 , a clamping protrusion 401 is provided on the inner wall of the first ring 111, and a clamping groove 402 is provided on the outer wall of the second ring 112, and the clamping protrusion 401 is slidably connected to the clamping groove 402. A clamping protrusion 401 is provided on the inner wall of the second ring 112, and a clamping groove 402 is provided on the outer wall of the third ring 113, and the clamping protrusion 401 is slidably connected to the clamping groove 402. A clamping protrusion 401 is provided on the inner wall of the third ring 113, and a clamping groove 402 is provided on the outer wall of the fourth ring 114, and the clamping protrusion 401 is slidably connected to the clamping groove 402. When two adjacent water rings 110 move axially relative to each other, the locking protrusion 401 slides axially along the corresponding locking groove 402. At the same time, the cooperation between the locking protrusion 401 and the locking groove 402 is used to limit the rotation of the water rings 110 around the axial direction.

[0033] In some specific embodiments of the present invention, as shown in FIG. 2 and FIG. 5 , the outer wall of the water ring 110 is provided with a plurality of water grooves 123 distributed in the circumferential direction. Each water groove 123 extends along the axial direction of the water ring 110. The water groove 123 is arranged to have a gradual depth change in the radial direction of the water ring 110. In this embodiment, the water groove 123 penetrates the water ring 110 from top to bottom along the axial direction of the water ring 110 on the circumferential side wall of the water ring 110. Moreover, the dimension of the water groove 123 along the radial direction of the water ring 110 is the depth dimension of the water groove 123, and the depth dimension of the water groove 123 gradually decreases from top to bottom. Alternatively, the depth dimension of the water groove 123 gradually increases from top to bottom. The water groove 123 is covered by the inner wall of the adjacent water ring 110 to form the waterway 120. Alternatively, an inclined wall 124 is arranged inside the water groove 123, and the inclined wall 124 is arranged obliquely along the axial direction of the water ring 110. The inclined wall 124 is opposite to the inner wall of the adjacent water ring 110. That is, the water groove 123 on the outer wall of the second ring 112 is covered by the inner wall of the first ring 111, and the water channel 120 is formed between the inclined wall 124 of the second ring 112 and the inner wall of the first ring 111. The water groove 123 on the outer wall of the third ring 113 is covered by the inner wall of the second ring 112, and the water channel 120 is formed between the inclined wall 124 of the third ring 113 and the inner wall of the second ring 112. The water groove 123 on the outer wall of the fourth ring 114 is covered by the inner wall of the third ring 113, and the water channel 120 is formed between the inclined wall 124 of the fourth ring 114 and the inner wall of the third ring 113. When the water ring 110 moves axially relative to the water ring 110, the lower end of the water groove 123 moves relative to the end of the adjacent water ring 110 as the water ring 110 moves axially. That is, when the second ring 112 moves downward relative to the first ring 111, the lower end of the water groove 123 on the second ring 112 gradually protrudes downward to the lower end surface of the first ring 111. As the second ring 112 moves downward, the aperture of the water outlet 121 formed between the water groove 123 of the second ring 112 and the inner wall of the first ring 111 gradually increases, and the change of the water column strength is realized in sequence. The water groove 123 between the second ring 112 and the third ring 113 and between the third ring 113 and the fourth ring 114 is also based on the same principle. Further, as shown in Figures 2, 5 and 7, the lower end of the inner wall of the water ring 110 is provided with a lip 140 protruding downward in the axial direction. The lip 140 is attached to the outer wall of the water ring 110 adjacent thereto. That is, the lip 140 of the first ring 111 is attached to the outer wall of the second ring 112, the lip 140 of the second ring 112 is attached to the outer wall of the third ring 113, and the lip 140 of the third ring 113 is attached to the outer wall of the fourth ring 114. The lip 140 and the corresponding water groove 123 form the water outlet 121 of the water channel 120.

[0034] In some embodiments of the present invention, as shown in FIG. 3, FIG. 5 and FIG. 7, the drive assembly 200 includes a plurality of groups of coaxially arranged drive segments 210. Each drive segment 210 is coaxially arranged in the water outlet mechanism 100. Each drive segment 210 is provided with an external thread 214, and each water ring 110 can rotate synchronously and coaxially relative to the drive assembly 200. Except for the water ring 110 located at the outermost side, the inner walls of the remaining water rings 110 are threadedly connected with the drive segments 210 in a one-to-one correspondence. In this embodiment, three drive segments 210 are arranged corresponding to the four water rings 110. The three drive segments 210 are respectively defined as the first segment 211, the second segment 212 and the third segment 213. The first ring 111 is the outermost water ring 110, and the first ring 111 is not connected to the drive segment 210. The first segment 211 can be provided with a long axis structure, the second segment 212 is provided with a hollow shaft body sleeved on the first segment 211, and the third segment 213 is provided with a hollow shaft body sleeved on the second segment 212. The first section 211, the second section 212 and the third section 213 are all provided with external threads 214, at least a portion of the external threads 214 on the first section 211 is not blocked by the second section 212, and at least a portion of the external threads 214 on the second section 212 is not blocked by the third section 213. The second ring 112 is threadedly connected to the first section 211, the third ring 113 is threadedly connected to the second section 212, and the fourth ring 114 is threadedly connected to the third section 213. The driving sections 210 will not rotate relative to each other around the axial direction, that is, the driving sections 210 rotate synchronously around the axial direction relative to the water outlet mechanism 100. The first section 211 can be fixedly connected to the joint 300. The first ring 111 is rotationally connected to the joint 300. When in use, the joint 300 and the driving section 210 are relatively fixed, and the first ring 111 is rotated by hand, and the first ring 111 drives the second ring 112, the third ring 113, and the fourth ring 114 to rotate synchronously. The first ring 111 is stationary relative to the joint 300 in the axial direction, and the second ring 112 rotates along the external thread 214 on the first section 211, so that the second ring 112 moves in the axial direction. The third ring 113 rotates along the external thread 214 on the second section 212, so that the third ring 113 moves in the axial direction. The fourth ring 114 rotates along the external thread 214 on the third section 213, so that the fourth ring 114 moves in the axial direction. Since each water ring 110 rotates synchronously around the corresponding driving section 210, the threads are used to drive each water ring 110 to move axially. At this time, the second ring 112 expands and contracts relative to the first ring 111, the third ring 113 expands and contracts relative to the second ring 112, and the fourth ring 114 expands and contracts relative to the third ring 113, thereby realizing the change in the aperture of the water outlet 121 of each waterway 120. By setting the pitch size on each driving section 210, the expansion and contraction amount of each water ring 110 when rotating can be controlled. The pitch size of each driving section 210 is set to be equal, so that the axial movement distance of each water ring 110 is synchronized. The driving assembly 200 also includes a limiter 500. The limiter 500 can be a plate, a shaft, etc.The limiting member 500 is inserted into each driving section 210 , and the limiting member 500 can be inserted into the ends of the first section 211 , the second section 212 and the third section 213 in the radial direction, so as to limit the relative rotation of each driving section 210 .

[0035] Among them, the water ring 110 can be directly connected to the corresponding driving section 210. For example, the second ring 112 and the third ring 113 extend out of the transverse plate in the radial direction, and the driving section 210 is penetrated by the corresponding transverse part. The inner wall of the transverse plate is provided with an internal thread and is threadedly connected with the external thread 214 of the driving section 210. Alternatively, the water ring 110 and the driving section 210 are indirectly threadedly connected through other components. For example, the water outlet mechanism 100 also includes a plurality of connecting seats 600. The second ring 112 is fixedly connected to a connecting seat 600, and the third ring 113 is fixedly connected to a connecting seat 600. The middle part of the connecting seat 600 is hollow, the driving section 210 is penetrated by the connecting seat 600, a through hole is formed in the middle part of the connecting seat 600, an internal thread is provided on the inner wall of the through hole, and the connecting seat 600 is threadedly connected to the driving section 210. The connection seat 600 is located above the water tank 123. The connection seat 600 is set as a hollow structure. The water in the water inlet cavity 130 can be diverted to each waterway 120 through the hollow part of each connection seat 600. The driving sections 210 can move relative to each other in the axial direction. Among them, a cover plate 700 can be installed at the bottom of the fourth ring 114, and the lower end of each driving section 210 can be abutted on the cover plate 700, and the cover plate 700 is used to limit the driving sections 210 from completely disengaging relative to the axial direction.
