[0056] Embodiments of this application provide a press-to-switch device, such as... Figures 1-17 As shown, the press-to-switch device includes a valve seat 1, a water circuit switching component 2, and a press-to-drive assembly. The water circuit switching component 2 is disposed in the valve seat 1 and is configured to perform a water circuit switch once every predetermined rotation angle. The press-to-drive assembly is configured to drive the water circuit switching component 2 to rotate.

[0057] The pressing drive assembly includes a rotor 4, a pressing element 5, and a first elastic element 6;

[0058] The rotor 4 is rotatably mounted on the valve seat 1 and connected to the water circuit switching component 2 to drive the water circuit switching component 2 to rotate; wherein, a plurality of guide structures 41 are arranged circumferentially at intervals on the outer peripheral surface of the rotor 4, each guide structure 41 including a helical surface 411; the pressing component 5 includes at least one sliding part 52, each sliding part 52 sliding in cooperation with one of the guide structures 41.

[0059] When the pressing member 5 is pressed, it can move downward along the axial direction of the rotor 4 from the initial position to the pressing position. The sliding part 52 slides from the first engagement position that cooperates with the guide structure 41 to the second engagement position. The sliding part 52 drives the rotor 4 to rotate by the predetermined angle through the cooperation with the spiral surface 411. The rotation of the rotor 4 drives the water circuit switching member 2 to rotate by the predetermined angle, so that the water circuit switching member 2 performs a water circuit switching.

[0060] After the pressing member 5 is released, the rotor 4 remains in its position. Under the action of the first elastic member 6, the pressing member 5 can move upward from the pressed position to the initial position, and each sliding part 52 moves upward to the first engaging position of the guide structure 41 corresponding to the position. The first elastic member 6 can be a spring or other elastic component.

[0061] It should be noted that the terms "upper" and "lower" as described in this application are defined based on the pressing force applied to the pressing member 5. The pressing force applied to the pressing member 5 is defined as downward. Therefore, the pressing member 5 moves downward from the initial position to the pressed position, and conversely, moves upward from the pressed position to the initial position.

[0062] In the technical solution provided by the embodiments of this application, by applying pressure to the pressing member 5, the rotor 4 can drive the water circuit switching member 2 to rotate, thereby realizing water circuit switching. After releasing the pressing member 5, the pressing member 5 returns upward to the initial position, while the rotor 4 remains in its current position, that is, the water circuit switching member 2 remains in the position after water circuit switching, and each sliding part 52 returns to its initial position and is located in the first engagement position of the guide structure 41 corresponding to one of the positions. In this way, when the pressing member 5 is pressed down again, the sliding part 52 moves from the first engagement position of the guide structure 41 to the second engagement position, thereby driving the rotor 4 to drive the water circuit switching member 2 to rotate by a predetermined angle, completing another water circuit switching. This process is repeated, and the water circuit switching device can perform one water circuit switching each time the pressing member 5 is pressed and released. Therefore, the water circuit switching is simple and convenient to operate using the driving component provided by the embodiments of this application.

[0063] In one embodiment of this application, the rotor 4 has the following structure: Figures 13-15 As shown, each guide structure 41 of the rotor 4 includes a helical surface 411 and a positioning groove 412 located at the lower end of the helical surface 411, the positioning groove 412 extending along the axial direction of the rotor 4; wherein, the second mating position is located within the positioning groove 412. The first mating position is the upper end position of the guide structure 41, and the first mating position can be located on the helical surface 411 above the positioning groove 412, or it can be located on a plane connected to the helical surface 411, etc.

[0064] As the pressing element 5 moves downward to the pressing position under the action of pressing force, the sliding part 52 moves along the spiral surface 411, thereby driving the rotor 4 to rotate at a predetermined angle. Then, it enters the positioning groove 412 from the spiral surface 411. Since the positioning groove 412 is axially arranged, the sliding part 52 will no longer drive the rotor 4 to rotate after entering the positioning groove 412. At this time, the rotor 4 and the water channel switching angle 2 are positioned at their respective locations, that is, maintaining the state after the water channel switching. The sliding part 52 entering the positioning groove 412 indicates that the pressing element 5 has moved to the pressing position. When the sliding part 52 enters the positioning groove 412 from the spiral surface 411, a certain amount of jumping will occur, so that the user can confirm by feel whether the pressing element 5 has been pressed to the pressing position when pressing the pressing element 5. Furthermore, by setting the positioning groove 412, it can be ensured that the water circuit switching component 2 switches the water circuit to the correct position. As long as the sliding part 52 enters the positioning groove 412 and moves linearly within the positioning groove 412, the water circuit switching component 2 is positioned in the position after the water circuit is switched. This can avoid the situation where the water circuit switching component 2 fails to switch to the correct position due to the pressing part 5 not being pressed down properly.

[0065] In one example, such as Figure 13 As shown, the helical surface 411 of each guide structure 41 of the rotor 4 faces upward, and the radially inner edge of the helical surface 411 gradually moves away from the central axis of the rotor 4 from top to bottom along the circumferential direction. The positioning groove 412 of each guide structure 41 is located below the helical surface 411 of the adjacent guide structure 41 and on the radially outer side, thereby forming a stepped structure above the positioning groove 412. When the pressing member 5 moves upward from the pressing position to the initial position, each sliding part 52 moves upward from the positioning groove 412 of the guide structure 41 to the helical surface 411 above the stepped structure, thereby returning to the first mating position of the other guide structure 41.

[0066] Figure 13 In the example shown, the rotor 4 is provided with three guide structures 41: a first guide structure 41a, a second guide structure 41b, and a third guide structure 41c. Figure 13 The arrow shown indicates that when the pressing member 5 moves upward from the pressed position to the initial position, one of its sliding parts 52 moves upward from the positioning groove 412 of the first guide structure 41a. As this sliding part 52 moves upward from the positioning groove 412 to the helical surface 411 of the second guide structure 41b, it simultaneously moves inward along the radial direction of the rotor 4, entering the second guide structure 41b. At this point, the sliding part 52 reaches the first engagement position of the second guide structure 41b. Pressing the pressing member 5 again moves the sliding part 52 along the second guide structure 41b back to the positioning groove 412. Releasing the pressing member 5 causes the sliding part 52 to move linearly upward to the first engagement position of the third guide structure 41c, and this cycle repeats.

[0067] In one embodiment, such as Figure 1 and Figure 2 As shown, the valve seat 1 includes a stator 13, and the rotor 4 is at least partially installed in the cavity of the stator 13. A sliding groove 132 is provided on the inner side of the stator 13. The pressing member 5 includes a pressing body 51 with a cylindrical body. Figure 11 and Figure 12 The pressing body 11 is shown as a cap-shaped structure including a cylindrical body (of course, the pressing body 11 is not limited to a cap-shaped structure). The cylindrical body is at least partially located inside the stator 13 and sleeved on the outside of the rotor 4. The sliding part 52 protrudes from the outside of the cylindrical body and is located within the slide groove 132. When the pressing member 5 moves between the initial position and the pressed position, the sliding part 52 moves linearly along the slide groove 132. The cross-sectional shape of the cylindrical body of the pressing body 11 is not limited and can be square or circular, etc. To facilitate the rotation of the rotor 4 and save space, the cylindrical body can be set to a circular cross-section, which also allows the pressing body 11 to fit into the inner cavity of the stator. In this way, the inner wall of the stator 13 can guide the movement of the cylindrical body to ensure stable movement.

[0068] Figure 8 A schematic diagram of the stator 13 in one example is shown. The stator 13 includes a sleeve portion 131, and a plurality of sliding grooves 132 are provided circumferentially spaced on the inner side of the sleeve portion 131. Each sliding groove 132 corresponds to and engages with a sliding part 52. A positioning connection portion 133 is provided below the sleeve portion 131. The positioning connection portion 133 is used to connect with the main structure of the valve seat 1 and can be fixed by welding. Figure 16 and Figure 17 The image shows the connection between the rotor 4 and the pressing member 5 within the sleeve portion 131, and the engagement of the sliding portion 52 with the groove 132.

[0069] In one example, the two sidewalls of the slide groove 132 are respectively provided with anti-detachment portions 1322 protruding towards each other at their upper ends to prevent the sliding portion 52 from detaching upward from the slide groove 132. The upper surface of each anti-detachment portion 1322 gradually slopes downward towards the other side, and the lower surface gradually slopes upward towards the other side, thus forming a roughly angular structure. This allows the sliding portion 52 to be engaged into the anti-detachment portion 1322 under pressure from above the slide groove 132. When the pressing member 5 moves upward from below to its initial position under the action of the first elastic member 6, the elastic force of the first elastic member 6 is insufficient to allow the sliding portion 52 to detach from the anti-detachment portion 1322. Therefore, when the pressing member 5 returns to its initial position from below, it will not detach from the slide groove 132.

[0070] In one embodiment, the sliding part 52 is configured to be movable in the radial direction of the rotor 4, and an elastic pressing member is provided on the stator 13. During the process of the pressing member 5 moving from the pressing position to the initial position, the elastic pressing member presses the sliding part 52 against the rotor 4 in the radial direction.

[0071] like Figure 1 and Figure 2 The example shown (reference) Figure 16 and Figure 17 The pressing component 5 includes a pressing body 51 and a plurality of sliding parts 52 spaced circumferentially along the pressing body 51; wherein, a plurality of mounting holes 511 are spaced circumferentially on the cylindrical body of the pressing body 51, the length direction of the mounting holes 511 is along the radial direction of the rotor 4 and penetrates the inner and outer sides of the cylindrical body, and each sliding part 52 is a sliding pin movably installed in the mounting hole 511, with both ends of the sliding pin extending out of the mounting hole 511 respectively.

[0072] refer to Figure 8 The bottom of the groove 132 is configured as an elastic arm 1321. The upper end of the elastic arm 1321 is fixed, and the lower end is configured to be able to swing elastically along the radial direction of the rotor 4. One end of the sliding pin is configured to contact the rotor 4, and the other end is configured to be located in the groove 132 and abut against the elastic arm 1321. The elastic pressure member is the elastic arm 1321.

[0073] As the sliding part 52 moves upward, the elastic arm 1321 applies a radially inward elastic force to the sliding part 52. Since the upper end of the elastic arm 1321 is fixed, the elasticity of the elastic arm 1321 gradually decreases from bottom to top. Thus, the higher up the sliding part 52 moves, the smaller the upward movement space of the elastic arm 1321 on the sliding part 52. In this way, when the sliding part 52 moves upward from the positioning groove 412 to the spiral surface 411 of another guide structure 41, it can move radially inward and abut against the rotor 4 under the action of the elastic arm 1321, so that the sliding part 52 can smoothly return to the initial position and engage with the first engagement position of the guide structure 41.

[0074] To clearly show the engagement state of the sliding part 52 with the rotor 4 and stator 13, Figure 18 and Figure 19 The press switching device shown conceals the press body 51 of the press member 5, showing only the sliding part 52. The sliding part 52 is a sliding pin that can move radially along the rotor 4, with one end abutting against the rotor 4 and the other end abutting against the elastic arm 1321 of the stator 13.

[0075] in, Figure 18The image shows the engagement state of the sliding part 52 and the guide structure 41 when the pressing member 5 is in the initial position. The sliding part 52 is located above the rotor 4, that is, the sliding part 52 is in the first engagement position with the guide structure 41. The anti-detachment parts 1322 on both sides of the slide groove 132 can prevent the sliding part 52 from detaching upward from the slide groove 132.

[0076] Figure 19 The image shows the state in which the sliding part 52 is located in the positioning groove 412 of the guide structure 41 when the pressing member 5 is in the pressed position, that is, the sliding part 52 is in the second mating position that mates with the guide structure 41. Figure 19 The image shows that one of the sliding parts 52 is located in the positioning groove 412 of the first guide structure 41a, and above it is the spiral surface 411 of the second guide structure 41b. When the sliding part 52 moves upward in a straight line to the initial position, it can move to the first mating position of the second guide structure 41b.

[0077] In one embodiment, the upper end of the rotor 4 is provided with a positioning hole 42 located at the center, one end of the first elastic member 6 is located in the positioning hole 42, and the other end rests on the pressing member 5.

[0078] Figure 11 and Figure 12 An example of a pressing member 5 is shown. The pressing body 51 of the pressing member 5 is a cap-shaped structure (including a top and sidewalls extending downward around the top, the sidewalls being formed as a cylinder that fits over the outside of the rotor 4). Multiple mounting holes 511 for mounting the sliding part 52 are provided on the sidewalls of the cap-shaped structure. A positioning post 512 is provided inside the pressing body 51 at a position corresponding to the positioning hole 42 of the rotor 4. The end of the first elastic member 6 away from the rotor 4 is positioned by fitting onto the positioning post 512.

[0079] In one embodiment, reference Figure 16 and Figure 17 The valve seat 1 is provided with a water chamber 17, a water inlet channel 121 and multiple water outlet channels 111. The water inlet channel 121 is configured to allow water to enter the water chamber 17, and the multiple water outlet channels 111 are configured to be able to connect and disconnect from the water chamber 17 by rotating the water circuit switching component 2.

[0080] The water circuit switching component 2 includes a switching body 21 located within the water cavity 17. The switching body 21 has at least one water passage hole 211. When the switching body 21 rotates to the point where the water passage hole 211 connects with the water outlet channel 111, the water outlet channel 111 connects with the water cavity 17, allowing water to flow from the water outlet channel 111. When the switching body 21 rotates to the point where the water passage hole 211 is misaligned with the water outlet channel 111, the water outlet channel 111 is blocked. The switching body 21 is configured such that for every predetermined angle rotation, for example, every 120° or 90° rotation, one of the water passage holes 211 rotates to connect with one of the water outlet channels 111. That is, for every predetermined angle rotation driven by the rotor 4, the water circuit switching component 2 performs one water circuit switching operation.

[0081] like Figure 10 As shown (in combination) Figure 16 and Figure 17 The water circuit switching component 2 also includes a connecting column 22 connected to the switching body 21. The connecting column 22 extends out of the valve seat 1 and connects to the rotor 4. For sealing, a shaft seal 15 is provided between the connecting body 22 and the valve seat 1. In order to enable the rotor 4 to drive the water circuit switching component 2 to rotate, the connecting column 22 can be connected to the rotor 4 to prevent rotation. Figure 10 The diagram shows that a flat connecting hole 221 is provided on the connecting column 22, and the lower end of the rotor 4 is set as a flat columnar body 43 that mates with the connecting hole 221, so that the two can be positioned in the circumferential direction, so that the rotor 4 can drive the water circuit switching component 2 to rotate.

[0082] In one embodiment, the valve seat 1 includes a first valve body 11 and a second valve body 12, which are fastened together to form a water cavity 17. The first valve body 11 has an outlet hole 112 corresponding to each water outlet channel 111. A second elastic element 3 is disposed between the second valve body 12 and the switching body 21, and the second elastic element 3 holds the switching body 21 against the first valve body 11. The second elastic element 3 can be a spring or other elastic component. Through the second elastic element 3, the switching body 21 remains against the first valve body 11 during rotation, thereby blocking the outlet hole 112 and disconnecting the water flow from the water outlet channel 111. The outlet hole 112 is only opened when the switching body 21 rotates to the point where the water passage 211 connects with the outlet hole 112.

[0083] In one example, a sealing gasket 14 is provided on the first valve body 11, and the switching body 21 is pressed against the sealing gasket 14. (Refer to...) Figure 4 and Figure 9 The first valve body 11 is provided with a sealing groove 114 that matches the shape of the sealing gasket 14, and the sealing gasket 14 can be installed in the sealing groove 114.

[0084] In one example, such as Figure 4 As shown, the first valve body 11 is provided with a plurality of support protrusions 117, which are used to support the switching body 21. By setting the support protrusions 117 to make point contact with the switching body 21, the first valve body 11 can avoid the sealing gasket 14 being flattened by the switching body 21 on the first valve body 11, and can ensure the balance of the switching body 21, so as to avoid the sealing gasket 14 being severely compressed due to uneven pressure on the switching body 21, thus affecting the sealing performance of the sealing gasket 14.

[0085] In one example, such as Figure 16 and Figure 17 As shown, a water pressure balancing chamber 115 is also provided between the switching body 21 and the first valve body 11, and the water pressure balancing chamber 115 is connected to the water chamber 17. To form the water pressure balancing chamber 115, a groove can be provided on the first valve body 11, and / or a groove can be provided on the switching body 21, the groove forming the water pressure balancing chamber between the first valve body 11 and the switching body 21.

[0086] After water enters the water chamber 17 through the water inlet channel 121, it will generate pressure on the side of the switching body 21 that is away from the first valve body 11, thereby generating a large pressure between the switching body 21 and the first valve body 11. This results in a large friction between the switching body 21 and the sealing gasket 14 during rotation, which will cause severe wear of the sealing gasket 14. By setting a water pressure balancing chamber 115 between the switching body 21 and the first valve body 11, the pressure on the side of the switching body 21 facing the first valve body 11 can be balanced with the pressure on the side away from the first valve body 11, thereby avoiding the problem of severe wear of the sealing gasket 14 due to water pressure.

[0087] The water pressure balancing chamber 115 and the water chamber 17 can be connected through a through hole on the switching body 21. This through hole can be a water passage hole 211 provided on the switching body 21, such as... Figure 16 and Figure 17 In the example shown, the switching body 21 is provided with two water passages 211. When one water passage 211 is connected to the water outlet channel 111, the other water passage 211 is connected to the water pressure balance chamber 115. Of course, other through holes can also be provided on the switching body 21 to achieve the connection between the water pressure balance chamber 115 and the water chamber 17.

[0088] Figures 3-5 A first valve body 11 is shown in one embodiment. Figures 6-7 A second valve body 12 is shown in one embodiment. A first valve body 11 is provided with a recessed first water groove 113, and a second valve body 12 is provided with a recessed second water groove 122. When the first valve body 11 and the second valve body 12 are fastened together, the first water groove 113 and the second water groove 122 together form a water cavity 17.

[0089] The second valve body 12 is provided with a water inlet channel 121, the first valve body 11 is provided with three water outlet channels 111, the first water tank 113 is provided with three water outlet holes 112 respectively connected to the water outlet channels, and the first water tank 113 includes a groove for forming a water pressure balance chamber 115.

[0090] When assembling the first valve body 11 and the second valve body 12, the switching body 21 of the water circuit switching component 2 is located between the first valve body 11 and the second valve body 12, and the connecting post 22 of the water circuit switching component 2 extends out of the central hole 116 of the first valve body 11 to connect with the rotor 4. The second elastic element 3 is installed between the switching body 21 and the second valve body 12. For positioning the second elastic element 3, as follows... Figure 6 and Figure 7 As shown, a first positioning hole 123 can be provided on the second valve body 12, and a second positioning hole 212 can be provided on the switching body 21. One end of the second elastic member 3 is located in the first positioning hole 123, and the other end is located in the second positioning hole 212. Then, multiple bolt connecting posts 119 provided on the first valve body 11 and multiple connecting ears 124 provided on the second valve body 12 are fixed together with bolts. For sealing, a sealing ring 16 is provided between the first valve body 11 and the second valve body 12.

[0091] The stator 13 is fixed to the side of the first valve body 11 opposite to the second valve body 12. A positioning mounting groove 118 can be provided on the first valve body 11. This positioning mounting groove 118 mates with the positioning connection part 133 of the stator 13. Because the pressing member 5 applies torque to the stator 13, the mating of the positioning mounting groove 118 and the positioning connection part 133 needs to be circumferentially positioned to prevent the stator 13 from rotating. The stator 13 can be fixed in the positioning mounting groove 118 by welding or other methods. The rotor 4 is inserted into the stator 13 and connected to the connecting post 22 of the water circuit switching member 2. Then, the pressing member 5 is installed, so that each sliding part 52 of the pressing member 5 mates with the sliding groove 132 of the stator 13 and with each guide structure 41 of the rotor 4.

[0092] The following is based on Figures 20-22 The process of water path switching component 2 rotating to switch water paths in a water path switching device in one embodiment is described.

[0093] In this example, the valve seat 1 is provided with three water outlet holes 112 that are connected to the respective water outlet channels 111. The three water outlet holes are the first water outlet hole 112a, the second water outlet hole 112b and the third water outlet hole 112c. The switching body 21 of the water circuit switching component 2 is provided with two water passage holes 211, namely the first water passage hole 211a and the second water passage hole 211b.

[0094] Figure 20The display shows that the switching body 21 is rotated to the state where the first water passage 211a is connected to the second water outlet 112b, and water flows out of the water outlet channel 111 corresponding to the second water outlet 112b.

[0095] After pressing the pressing element 5 to the down position and releasing it, the rotor 4 drives the switching body 21 to rotate 120 degrees counterclockwise, and the water circuit switching device... Figure 20 The state shown is transformed into Figure 21 In the state shown, the second water passage 211b is connected to the first water outlet 112a, so that water flows out of the water outlet channel 111 corresponding to the first water outlet 112a.

[0096] After pressing the pressing element 5 again and releasing it, the rotor 4 drives the switching body 21 to rotate 120 degrees counterclockwise, and the water circuit switching device moves from... Figure 21 The state shown is transformed into Figure 22 In the state shown, the second water passage 211b is connected to the third water outlet 112c, so that water flows out of the water outlet channel 111 corresponding to the third water outlet 112c.

[0097] This process is repeated. Each time the pressing part 5 is pressed, the switching body 21 rotates 120 degrees to perform a water circuit switch.

[0098] It is understandable that the number of water outlet channels 111 can vary and is not limited to three; four or more can be set. The predetermined angle at which the switching body 21 needs to rotate also needs to be adapted accordingly.

[0099] An embodiment of this application also provides a water outlet device, which includes the push-button switching device described above. The water outlet device can be a shower head, faucet, or overhead shower, or any other device requiring water path switching.
