Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] This utility model relates to a water outlet device, including a water outlet mechanism 100 and a drive assembly 200.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the water outlet mechanism 100 includes at least two water rings 110, which are nested sequentially from the inside out. The number of water rings 110 can be two, three, four, or more. Adjacent water rings 110 can move relative to each other axially. Multiple water channels 120 are defined between adjacent water rings 110. One end of each water channel 120 serves as an inlet end 122, and the other end serves as an outlet end 121. When two water rings 110 are provided, multiple water channels 120 are defined between the inner wall of the outer water ring 110 and the outer wall of the inner water ring 110. When the number of water rings 110 is three or more, as in this embodiment, four water rings 110 are provided. Each water ring 110 is a hollow cylindrical ring. The four water rings 110 are defined from the outside to the inside as the first ring 111, the second ring 112, the third ring 113, and the fourth ring 114. The first ring 111 has the largest inner diameter, followed by the second ring 112, and the fourth ring 114 has the smallest inner diameter. The first ring 111 is fitted over the second ring 112. The inner wall of the first ring 111 and the outer wall of the second ring 112 are in contact with each other, defining multiple water channels 120 between them. The second ring 112 is fitted over the third ring 113. The inner wall of the second ring 112 and the outer wall of the third ring 113 are in contact with each other, defining multiple water channels 120 between them. The third ring 113 is fitted over the fourth ring 114. The inner wall of the third ring 113 and the outer wall of the fourth ring 114 are in contact with each other, defining multiple water channels 120 between them. As shown in the diagram, each water channel 120 is formed along the axial direction of the water ring 110. As shown in the diagram, the upper end of each water channel 120 is the inlet end 122, and the lower end is the outlet end 121. When adjacent water rings 110 move axially relative to each other, each water channel 120 changes accordingly, and the diameter of the 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. The drive assembly 200 can control the asynchronous axial movement of each water ring 110 using different shafts, or it can control the synchronous axial movement of each water ring 110. Alternatively, when the drive assembly 200 changes the relative position of each water ring 110, the water rings 110 move synchronously relative to each other, that is, the diameter of the outlet end 121 of each water channel 120 increases or decreases synchronously, thereby causing the spray intensity of the formed water column to increase or decrease synchronously. The water outlet device can be applied to spray guns, shower heads, etc. In this utility model, the water outlet device can be applied to faucets, shower heads, and other water-using equipment. The inlet end 122 of each water channel 120 is connected to the water inlet side of the water-using equipment. When water is supplied, water flows into the water channel 120 from the inlet end 122 of each water channel 120 and forms a water jet from the outlet end 121 of each water channel 120. Initially, the lower end faces of each water ring 110 can be flush, at which time the orifice diameter of the outlet end 121 of each water channel 120 is equal, and the water jets sprayed from each water channel 120 are of equal diameter. When adjustment is required, the relative movement of each water ring 110 is controlled by the drive component 200. In this embodiment, as shown... Figure 6 and Figure 7 As shown, taking the first ring 111 as a reference, the first ring 111 remains relatively stationary in the axial direction. Then, the second ring 112 moves axially downward relative to the first ring 111, with the lower end face of the second ring 112 protruding downward from the lower end face of the first ring 111. The third ring 113 moves axially downward relative to the second ring 112, with the lower end face of the third ring 113 protruding downward from the lower end face of the second ring 112. The fourth ring 114 moves axially downward relative to the third ring 113, with the lower end face of the fourth ring 114 protruding downward from the lower end face of the third ring 113. Adjacent water rings 110 are distributed in a stepped pattern. After the relative axial movement, the outlet end 121 of the water channel 120 becomes larger. Under the condition of equal water supply, the larger outlet end 121 results in a thicker water jet, while the water spray intensity decreases. By adjusting the axial relative position between adjacent water rings 110 through the drive component 200, the aperture change of the outlet end 121 of the water channel 120 can be flexibly controlled, thereby achieving stepless adjustment of the water column intensity.

[0031] In some specific embodiments of this utility model, such as Figure 5 and Figure 7 As shown, each water ring 110 defines an inlet cavity 130, and the inlet end 122 of each water channel 120 communicates with the inlet cavity 130. In this embodiment, the first ring 111 is convex in shape, hollow inside and open 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 gap 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 interior of the first ring 111, forming the inlet cavity 130. The drive assembly 200 coaxially enters the first ring 111 from the upper end and connects to the second ring 112, the third ring 113, and the fourth ring 114. A connector 300 can be connected to the upper opening of the first ring 111, which is used to connect to an external water supply pipe, etc. After water enters the inlet cavity 130, it is diverted to each water channel 120.

[0032] A limiting structure is provided between adjacent water rings 110. The limiting structure includes a locking protrusion 401 and a locking groove 402. The locking groove 402 is disposed on one of the two adjacent water rings 110, and the locking protrusion 401 is disposed on the other. The locking protrusion 401 and the locking groove 402 extend along the axial direction of the water rings 110. In this embodiment, as... Figure 2As shown, the inner wall of the first ring 111 has a locking protrusion 401, and the outer wall of the second ring 112 has a locking groove 402, with the locking protrusion 401 slidingly engaging with the groove 402. The inner wall of the second ring 112 has a locking protrusion 401, and the outer wall of the third ring 113 has a locking groove 402, with the locking protrusion 401 slidingly engaging with the groove 402. The inner wall of the third ring 113 has a locking protrusion 401, and the outer wall of the fourth ring 114 has a locking groove 402, with the locking protrusion 401 slidingly engaging with the 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. Simultaneously, the engagement of the locking protrusion 401 and the locking groove 402 restricts rotation between the water rings 110 around the axial direction.

[0033] In some specific embodiments of this utility model, such as Figure 2 and Figure 5 As shown, the outer wall of the water ring 110 is provided with a plurality of circumferentially distributed water grooves 123. Each water groove 123 extends along the axial direction of the water ring 110. The water grooves 123 are configured to have a gradually changing depth in the radial direction of the water ring 110. In this embodiment, the water grooves 123 penetrate the water ring 110 from top to bottom along the axial direction of the water ring 110 on the circumferential sidewall. Furthermore, the dimension of the water groove 123 in 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 may gradually increase from top to bottom. The water grooves 123 are covered by the inner wall of the adjacent water ring 110 to form a water channel 120. Alternatively, the interior of the water groove 123 may be provided with an inclined wall 124, which is inclined along the axial direction of the water ring 110. The inclined wall 124 and the inner wall of the adjacent water ring 110 are opposite to each other. That is, the water trough 123 on the outer wall of the second ring 112 is covered by the inner wall of the first ring 111, and a 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 trough 123 on the outer wall of the third ring 113 is covered by the inner wall of the second ring 112, and a 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 trough 123 on the outer wall of the fourth ring 114 is covered by the inner wall of the third ring 113, and a 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, the lower end of the water trough 123 expands and contracts 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 face of the first ring 111. As the second ring 112 moves downward, the diameter of the outlet end 121 formed between the water groove 123 of the second ring 112 and the inner wall of the first ring 111 gradually increases, thereby realizing the change in water column intensity. 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, operates on the same principle. Furthermore, as... Figure 2 , Figure 5 and Figure 7 As shown, the lower end of the inner wall of the water ring 110 is provided with a lip 140 protruding downward along the axial direction. The lip 140 is attached to the outer wall of the adjacent water ring 110. 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 trough 123 form the outlet end 121 of the water channel 120.

[0034] In some embodiments of this utility model, such as Figure 3 , Figure 5 and Figure 7As shown, the drive assembly 200 includes multiple coaxially arranged drive segments 210. Each drive segment 210 is coaxially inserted into 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 outermost water ring 110, the inner walls of the other water rings 110 are threadedly connected to the drive segments 210 one by one. In this embodiment, three drive segments 210 are provided for the four water rings 110. The three drive segments 210 are defined as the first segment 211, the second segment 212, and the third segment 213, respectively. The first ring 111 is the outermost water ring 110 and is not connected to the drive segments 210. The first segment 211 can be provided with a long shaft structure, the second segment 212 is provided with a hollow shaft sleeved on the first segment 211, and the third segment 213 is provided with a hollow shaft sleeved on the second segment 212. The first segment 211, the second segment 212, and the third segment 213 are all provided with external threads 214. At least a portion of the external threads 214 on the first segment 211 are not obstructed by the second segment 212, and at least a portion of the external threads 214 on the second segment 212 are not obstructed by the third segment 213. The second ring 112 is threadedly connected to the first segment 211, the third ring 113 is threadedly connected to the second segment 212, and the fourth ring 114 is threadedly connected to the third segment 213. The drive segments 210 do not rotate relative to each other around the axial direction; that is, the drive segments 210 rotate synchronously around the axial direction relative to the water outlet mechanism 100. The first segment 211 can be fixedly connected to the connector 300. The first ring 111 is rotatably connected to the connector 300. In use, the connector 300 and the drive segment 210 are relatively fixed. Rotating the first ring 111 by hand causes the first ring 111 to drive the second ring 112, the third ring 113, and the fourth ring 114 to rotate synchronously. The first ring 111 remains stationary axially relative to the connector 300. When the second ring 112 rotates, it rotates along the external thread 214 on the first segment 211, thus moving axially. Similarly, the third ring 113 rotates along the external thread 214 on the second segment 212, moving axially. The fourth ring 114 rotates along the external thread 214 on the third segment 213, moving axially. Since each water ring 110 rotates synchronously around its corresponding drive segment 210, the threads 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 changing the diameter of the outlet end 121 of each water channel 120. The expansion and contraction of each water ring 110 during rotation can be controlled by setting the pitch size on each drive segment 210. The pitch of each drive section 210 is set to be equal to achieve synchronous axial movement of each water ring 110. The drive assembly 200 also includes a limiting component 500. The limiting component 500 can be a plate, shaft, etc.The limiting member 500 is inserted into each drive segment 210. The limiting member 500 can be inserted radially into the ends of the first segment 211, the second segment 212 and the third segment 213, thereby limiting the relative rotation of each drive segment 210.

[0035] In this design, the water ring 110 can be directly connected to the corresponding drive section 210. For example, the second ring 112 and the third ring 113 extend radially into horizontal plates, through which the drive section 210 passes. The inner wall of the horizontal plate has internal threads that connect with the external threads 214 of the drive section 210. Alternatively, the water ring 110 and the drive section 210 can be indirectly connected by threads through other components. For example, the water outlet mechanism 100 also includes several connecting seats 600. The second ring 112 is fixedly connected to one connecting seat 600, and the third ring 113 is fixedly connected to one connecting seat 600. The connecting seat 600 is hollow in the middle, through which the drive section 210 passes. A through hole is formed in the middle of the connecting seat 600, and internal threads are provided on the inner wall of the through hole. The connecting seat 600 is threadedly connected to the drive section 210. The connecting seat 600 is located above the water tank 123. The connecting seat 600 is designed with a hollow structure, allowing water from the inlet chamber 130 to flow into each water channel 120 through the hollow openings of each connecting seat 600. Each drive section 210 can move relative to each other axially. A cover plate 700 can be installed at the bottom of the fourth ring 114, and the lower end of each drive section 210 can abut against the cover plate 700, thereby preventing the drive sections 210 from completely disengaging relative to each other axially.
