[0002] As people's living standards improve, more and more water outlets are used in home decoration, such as kitchen showers, shower heads, countertop faucets, etc. These water outlets often have more than one water outlet gear and more than one water outlet flow rate. When using, users can switch the water spray and water outlet flow rate through various operating parts to meet people's needs in different usage scenarios. However, these functions also bring more operating buttons and more complicated operations.

[0003] After turning off the water, users often need to manually reset the button for controlling the water flow, otherwise the next time the water flows out, it is possible that the water will flow out at a large flow rate, causing some unnecessary trouble. However, it is often difficult for users to remember to manually reset the button for controlling the water flow after turning off the water, so the user experience is relatively poor.

For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] refer to Figure 1-Figure 20 This embodiment provides a water outlet device with automatic water shut-off and reset, including a water outlet device body 1, a water channel switching component 2 and a flow control component 3; the flow control component is a control structure 3 for automatic water shut-off and reset.

[0049] The water outlet device body 1 has a water inlet channel 11, a first water outlet channel 12 and a second water outlet channel 13; the water channel switching component 2 is used to connect the first water outlet channel 12 or the second water outlet channel 13 with the water inlet channel 11 to achieve the switching of the water spray of the water outlet device.

[0050] Specifically, the waterway switching assembly 2 in this embodiment specifically includes a boat-shaped switch 21 and a switching shaft 22. The switching shaft 22 is arranged along the axial direction of the water outlet device body 1, and the boat-shaped switch 21 is used to pull the switching shaft 22 to reciprocate along the axial direction of the water outlet device body 1. The first water outlet channel 12 and the second water outlet channel 13 are arranged in concentric circles, and a sealing member 23 is provided on the side wall of the switching shaft 22; in this way, the switching shaft 22 can seal the connection between the first water outlet channel 12 and the water inlet channel 11, or seal the connection between the second water outlet channel 13 and the water inlet channel 11 during the reciprocating motion, so as to realize the switching of the water spray. In this embodiment, the first water outlet channel 12 is a shower water outlet, and a bubbler is provided at the end of the second water outlet channel 13 to form a bubble water outlet.

[0051] The water shut-off automatic reset control structure 3 is arranged in the water inlet flow channel 11, and is used to control the water flow area of ​​the water inlet flow channel 11, so as to realize the switching of the water flow rate. After the water is shut off, the control structure automatically resets to the initial position, so that the water flow rate is roughly the same each time the water is turned on, and the user will not forget to reset the control structure, causing the flow rate to be too large or too small when the water is turned on next time, thereby improving the user experience.

[0052] In order to achieve the above-mentioned effect, the water-off automatic reset control structure 3 in this embodiment includes: an operating member 31, a movable member 32, a first elastic member 33, a fixed member 34 and a control member 35; in this embodiment, the operating member 31 is a button, and the movable member 32 has a translational freedom along the axial direction of the button; so that the movable member 32 moves from the first position to the second position under the action of water pressure when the water is turned on. Fig.11 This is a schematic diagram of the first position. Fig.13 It is a schematic diagram of one of the second positions, and the first elastic member 33 is squeezed to accumulate elastic restoring force. Thus, when the water is turned off, the movable member 32 is moved from the second position to the first position by the action of the first elastic member 33; when the movable member 32 is in the first position, the movable member 32 and the fixed member 34 form a first guide surface; the first guide surface is a continuous inclined surface.

[0053] The control member 35 cooperates with the first guide surface under the action of the second elastic member 36, so that the control member 35 moves along the extension direction of the first guide surface, and finally moves to the highest point of the first guide surface, thereby achieving the purpose of automatically resetting the control member 35 when the water is turned off. In this way, it can be ensured that the control structure is in the initial position after the water is turned off, and the occurrence of misoperation can be effectively avoided.

[0054] In order to form the above-mentioned first guide surface, the fixed member 34 is provided with a first inclined surface 341 on the side facing the control member 35, and the movable member 32 is provided with a second inclined surface 321 on the side facing the control member 35. When the movable member 32 is located at the first position, the first inclined surface 341 and the second inclined surface 321 are combined to form the first guide surface. Taking the water inlet channel 11 as the reference position, the higher end point of the first inclined surface 341 relative to the water inlet channel 11 is the first inclined surface high point 3411, and the lower end point relative to the water inlet channel 11 is the first inclined surface low point 3412. The higher end point of the second inclined surface 321 relative to the water inlet channel 11 is the second inclined surface high point 3211, and the lower end point relative to the water inlet channel 11 is the second inclined surface low point 3212. The first guide surface is combined by the first inclined surface 341 and the second inclined surface 321. The first guide surface may be a continuous slope, which may be understood as a completely continuous slope or an approximately continuous slope. The so-called completely continuous slope means that the first slope's low point 3412 is at the same height as the second slope's high point 3211. The so-called approximately continuous slope means that the first guide surface may have a first slope's low point 3412 higher than the second slope's high point 3212, such as Fig.11 Specifically, the fixing member 34 extends a plurality of first ribs 342 along the axial direction of the control structure from one side of the fixing member 34 facing the control member 35. The first ribs 342 include a first portion 3421 and a second portion 3422. The first portion 3421 is wider than the second portion 3422, so as to define a first region 34221 and a second region 34222 on both sides of the second portion 3422 along the width direction.

[0055] A plurality of second ribs 322 are extended, and a channel for inserting the second ribs 322 is formed between two adjacent first ribs 342. The second rib 322 includes an insertion portion 3221 having a width smaller than that of the channel and an extension portion 3222 having a width larger than that of the insertion portion 3221; the extension portion 3222 is placed in the first region 34221 relative to the protruding region 34221 of the insertion portion 3221, so that the portion 32222 of the extension portion 3222 placed outside the first region 34221 is combined with the second region 34222 to form a groove 37 for the control member 35 to enter and exit along the axial direction. In this way, when the control member 35 enters the groove 37, the control member 35 moves to the highest position, and at this time, the second elastic member 36 is in a restored state, thereby occupying part of the water inlet flow channel 11 and reducing the flow rate of the water inlet flow channel 11.

[0056] The bottom of the second part 3422 and the extension part 3222 are respectively provided with the first inclined surface 341 and the second inclined surface 321; when the movable part 32 is located in the first position, the top of the extension part 3222 is separated from the first part 3421 by a certain distance, and the first inclined surface 341 and the second inclined surface 321 are combined to form a first guide surface; in this way, the extension part 3222 can move upward under the action of water pressure when the water is turned on, so that when the movable part 32 is located in the second position, the top of the extension part 3222 and the first part 3421 are pressed against each other for limiting, and the first inclined surface 341 and the second inclined surface 321 form a second guide surface, and the second guide surface can be a stepped surface, with the water inlet channel 11 as the reference position, that is, the low point 3412 of the first inclined surface is lower than the high point 3211 of the second inclined surface.

[0057] The operating member 31 is linked with a pressing member 38, and a ratchet 381 is provided on the side of the pressing member 38 facing the control member 35; the control member 35 includes a flow-limiting rod 351 and a moving slider 352 connected to the flow-limiting rod 351 as a guide block, and a protrusion 3521 is provided on the outer periphery of the moving slider 352 to cooperate with the ratchet 381. When the pressing member 38 is driven downward by an external force, the ratchet 381 and the protrusion 3521 abut and cooperate to drive the moving slider 352 to rotate around the axis by a certain angle, and move downward along the axis to separate from the second guide surface. After the rotation, the protrusion 3521 of the moving slider 352 abuts against the second guide surface again under the action of the second elastic member 36, so as to enter the groove 37 along the second guide surface. When the operating member 31 is pressed again, the ratchet 381 and the protrusion 3521 abut against each other to drive the movable slider 352 to rotate around the axis at a certain angle, and move downward along the axis to separate from the groove 37. After the rotation, the movable slider 352 is abutted against the second guide surface again under the action of the second elastic member 36 by the protrusion 3521, so that the step abutting against the guide surface is at the lowest position. At this time, the flow limiting rod 351 will completely open the water inlet channel 11, causing the water flow area of ​​the water inlet channel 11 to become larger and the flow rate to become larger. When the user presses the operating member 31 again, the flow rate becomes smaller again, and this reciprocating cycle is formed. In this embodiment, the movable member 32 includes a movable step 323 and a movable frame 324 that are fixedly assembled together; the second rib 322 is provided on the movable step 323;

[0058] The movable step 323 extends radially outward to form a circle of convex edges 3231 , and the movable frame 324 has a cavity for accommodating the movable step, and the inner wall of the cavity extends radially inward to form a boss 3241 that abuts against the lower surface of the convex edge.

[0059] The lower end of the fixing member 34 passes through the moving step 323 and enters the cavity. One end of the first elastic member 33 abuts against the gasket 3242 at the bottom of the cavity, and the other end abuts against the lower end of the fixing member. The fixing member 34 is placed in the part outside the cavity, and protrudes radially outward to form a limiting wall 343 that limits the rising height of the movable member 32. When the movable member 32 is in the first position, there is a certain distance between the limiting wall 343 and the upper end surface of the movable frame 324. When water is flowing, the water pressure drives the movable member 32 to move upward along the axial direction until the limiting wall 343 and the upper end surface of the movable frame 324 abut against each other to limit the position. At this time, the movable member 32 moves from the first position to the second position and squeezes the first elastic member 33 to accumulate elastic reset force. In addition, in this embodiment, the side of the movable frame 324 and the water outlet device body are sealed by a first Y-shaped ring 3243, and the rod portion of the flow limiting rod 351 is inserted into the bottom of the movable frame 324 and is sealed and connected to the movable frame 324 by a second Y-shaped ring 3244.

[0060] The whole working process is as follows:

[0061] Initial state: Figure 4 As shown, the body 1 is provided with a first limiting portion 111, and the movable frame 324 is provided on the first limiting portion 111, so that the movable frame 324 can be fixed without the effect of water pressure, and a gasket 3242 is provided inside the movable frame 324, and a first elastic member 33 is provided on the gasket 3242, and the gasket 3242 provides a supporting force for the first elastic member 33. At this time, the first elastic member 33 is in a natural state without being acted upon by an external force, and the movable step 323 is provided with a convex edge 3231 provided on the top of the movable frame 324, and fixedly matched with the movable frame 324, so that the movable step 323 can move with the movable frame 324. A groove is provided at the bottom corresponding to the top of the movable frame 324, and the current limiting rod 351 passes through the groove, so that the movable frame 324 can move along the current limiting rod 351. The body 1 is provided with a limiting groove 113, the bottom of the current limiting rod is arranged in the limiting groove 113, a second elastic member 36 is arranged between the limiting groove 113 and the bottom of the current limiting rod 351, and the bottom of the current limiting rod 351 moves along the limiting groove 113 under the action of the second elastic member 36. The body 1 is provided with a second limiting portion 112, the flange of the fixing member 34 is arranged in the second limiting portion 112 and fixed in the body 1, the moving frame 324 is located below the flange of the fixing member 34, the moving frame 324 has a certain distance from the flange of the fixing member 34, or the moving step 323 has a certain distance from the flange of the fixing member 34, and the distance can be used for the moving frame 324 to move, and can also be understood as the maximum moving distance of the moving frame 324.

[0062] The fixed member 34 has a first rib 342, the first rib 342 has a first inclined surface 341, the movable member 32 has a second rib 322, the second rib 322 has a second inclined surface 321, the movable slider 352 is located in the groove 37 formed by the first rib 342 and the second rib 322, and the first inclined surface 341 and the second inclined surface 321 are combined to form a first guide surface. Fig.11 As shown, when the operating member 31 is pressed in the initial state, the movable slider 352 has an inclined surface that is compatible with the first inclined surface 341 and the second inclined surface 321. The movable slider 352 slides along the second inclined surface 321, then along the first inclined surface 341, and finally returns to the groove 37 again. At this time, the low point 3412 of the first inclined surface is at the same height as the high point 3211 of the second inclined surface, or, the first guide surface can be composed of two inclined surfaces in which the high point 3211 of the second inclined surface is lower than the low point 3412 of the first inclined surface (the height is relative to the water inlet channel 11). In this way, the movable slider 352 can smoothly move from the second inclined surface 321 to the first inclined surface 341, and finally return to the groove 37. Alternatively, the operating member 31 is pressed to make the movable slider 352 move up and down and stay in the original groove 37. At this time, no matter how the operating member 31 is pressed to switch the gear, the gear at the initial position is always maintained, thereby realizing the fixed setting of the initial gear.

[0063] Water flow status: Fig.13 As shown, a small amount of water can flow through at this time. Since the elastic coefficient of the second elastic member 36 is greater than the elastic coefficient of the first elastic member 33, the movable frame 324 is subjected to the water pressure of the water inlet channel 11 at this time, and cannot produce a compression effect on the second elastic member 36. Therefore, only the movable frame 324 is subjected to the water pressure and overcomes the elastic force of the first elastic member 33 to move upward, that is, it moves in the direction of the flange close to the fixing member 34. At this time, the relative positions of the first inclined surface 341 and the second inclined surface 321 are changed, that is, the second inclined surface 321 is raised relative to the water inlet channel 11, and the high point 3211 of the second inclined surface is higher than the low point 3412 of the first inclined surface. The side walls of the second inclined surface 321 and the first rib 342 form a second guide surface. The second guide surface can be a stepped step, and the movable slider 352 can be clamped on the step. The depth of the stepped step is less than the depth of the groove 37, which can be used for switching gears.

[0064] Gear switching: Fig.15 As shown, by pressing the operating member 31, the small flow rate in the initial state can be converted into a large flow rate state. By pressing the operating member 31, the second elastic member 36 is indirectly acted on, so that the movable slider 352 moves downward. The movable slider 352 completes a certain angle of rotation with the cooperation of the pressing member 38. The movable slider 352 can slide along the second inclined surface 321 and be fixed to the stepped step to complete the switching from small flow rate to large flow rate.

[0065] Pressing the operating member 31 again can switch from large flow to small flow. The movable slider 352 completes a certain angle of rotation with the cooperation of the pressing member 38. The movable slider 352 can slide along the first inclined surface 341 and be fixed in the groove 37 to complete the switch from large flow to small flow.

[0066] Water stop reset state: close the water inlet channel 11, at this time, the movable frame 324 is no longer affected by the water pressure, the first elastic member 33 has a downward restoring force, the movable frame 324 and the movable step 323 move downward, that is, move in the direction close to the water inlet channel 11, the movable frame pair 324 has a downward force on the movable slide 325, the movable slide 325 moves downward, the movable frame 324 returns to the first limit portion 111 of the body 1 to cooperate and fix, the second inclined surface 321 of the movable frame 324 is fixed with the first inclined surface 341 The first guide surface is assembled. Since the movable slider 352 is in contact with the second inclined surface 321, in order to push the movable slider 352 out of the second guide surface, that is, the stepped step, the second inclined surface 321 must move to form a continuous inclined surface with the first inclined surface 341, or the second inclined surface 321 is closer to the water inlet channel than the first inclined surface 341. With the cooperation of the pressing piece 38, a certain angle of rotation is completed, and the first movable slider 325 can slide along the first inclined surface 341 into the groove 37 and return to the initial state of small flow.

[0067] Example 2

[0068] The control member 35 in the first embodiment is used to control the flow rate. In this embodiment, the control member 35 is used to control the opening and closing of the water inlet flow channel 11. That is, when the water is turned off, the control member 35 opens the water inlet flow channel 11. After the water is turned on, the user can realize the cyclic switching between water stopping and water passing by pressing the operating member 31. When the water is stopped, it is only necessary to change the flow limiting rod 351 in the embodiment from opening part of the water inlet flow channel 11 to completely closing the water inlet flow channel 11.

[0069] Example 3

[0070] In Example 1, the movable part 32 moves from the first position to the second position along the axial direction of the control structure; in this embodiment, the movable part 32 moves from the first position to the second position along the radial direction of the control structure, which can also achieve the same effect as in Example 1. In general, it is sufficient to allow the movable part to be able to form a first guide surface with the fixed part after moving from the second position to the first position. To achieve radial movement of the movable part, the surface of the movable part 32 that is affected by water pressure can be changed from the bottom to the side, so that the moving direction of the movable part 32 after being affected by water pressure changes from axial to radial. It is also possible to set up another movable part that is affected by water pressure, and the movable part and the movable part 32 are reversingly matched, so that the moving part moves in the axial direction, and after reversing, the movable part 32 changes to move in the radial direction.

[0071] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this.
