[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] In the description of the present invention, it should be understood that the descriptions involving orientation, such as left, right, etc., the orientation or positional relationship indicated are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0047] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0048] In the related art, a water outlet device adopts a push-button water circuit switching structure, in which the valve core is locked to a set position or unlocked from a set position by a push button. After being unlocked, the valve core is reset to the initial position by a reset spring. However, due to the presence of a certain water pressure in the water outlet device, in order to ensure the water output, the water outlet device has a larger water sealing area of ​​the valve core, which also makes its pressure-bearing area large. The pressure of the water pressure acting on the valve core is relatively large. If the elastic force of the reset spring is not large enough, it is very easy to cause problems such as the valve core being unable to reset and the water outlet device failing. If a reset spring with a larger elastic force is set, the pressing force required to drive the valve core with the button is larger, which makes it more laborious for the user to use and the user experience is poor.

[0049] Reference below Figures 1 to 11 The water outlet switching device according to an embodiment of the utility model is described.

[0050] like Figures 1 to 5As shown, according to a specific embodiment of the first aspect of the utility model, the water outlet switching device comprises: a valve body 100, a main valve core 200, a control component, and a pressure relief component. The valve body 100 is provided with a valve cavity 101 and a water inlet 102, a first water outlet 103, and a second water outlet 104 respectively connected to the valve cavity 101; the main valve core 200 is movably arranged in the valve cavity 101, and the main valve core 200 can be moved to a first position connecting the water inlet 102 and the first water outlet 103, and the main valve core 200 is 00 can move to the second position connecting the water inlet 102 and the second water outlet 104; the control component is arranged on the valve body 100, including a driving mechanism and a reset mechanism, the driving mechanism can drive the main valve core 200 to move from the first position to the second position, and can lock the main valve core 200 in the second position or unlock the main valve core 200 from the second position, and the reset mechanism can drive the main valve core 200 to move from the second position to the first position; the pressure relief component is arranged on the main valve core 200 or the valve body 100.

[0051] Among them, the main valve core 200 or the valve body 100 is provided with a pressure relief channel connected to the outside of the valve cavity 101, and the pressure relief component can block or open the pressure relief channel. When the main valve core 200 is unlocked from the second position, the pressure relief component opens the pressure relief channel to reduce the water pressure in the valve cavity 101, reduce the water pressure on the main valve core 200, reduce the reset resistance of the main valve core 200, reduce the occurrence of abnormal reset of the main valve core 200, and improve the reliability of the use of the water outlet switching device.

[0052] Specifically, when the main valve core 200 is locked in the second position, the water inlet 102 and the second water outlet 104 are connected, and water flows out from the second water outlet 104. At the same time, the water pressure also acts on the main valve core 200 that blocks the first water outlet 103. When the main valve core 200 is unlocked, the pressure relief channel is opened, and part of the water is discharged from the pressure relief channel, reducing the water pressure in the valve cavity 101, so that the movement resistance of the main valve core 200 is reduced. The reset mechanism can reset the main valve core 200 to the first position by a smaller reset force, thereby reducing the occurrence of abnormal reset of the main valve core 200 and improving the reliability of the water outlet switching device. At the same time, a reset mechanism with a smaller reset force can be configured to facilitate user operation and be more convenient to use.

[0053] In some embodiments of the utility model, the control component is an unlocking mechanism, which includes a sliding seat 310, a sliding member 320, a locking member 330 and a reset spring 340. The sliding seat 310 is fixedly arranged on the valve body 100, the sliding member 320 is movably arranged on the sliding seat 310, the locking member 330 is connected to the main valve core 200, and the reset spring 340 forms a reset mechanism. Pressing the sliding member 320 can switch the locking member 330 among the initial position, the locking position and the unlocking position. When the locking member 330 moves to the unlocking position, it can trigger the pressure relief component to open the pressure relief channel, thereby meeting the pressure relief requirements.

[0054] Specifically, the unlocking mechanism is a self-locking button structure (such as a PUSH-PUSH unlocking mechanism), which can switch the locking member 330 between the initial position and the locked position by pressing the sliding member 320. When switching, the locking member 330 needs to move to an unlocking position that is farther away (relative to the sliding seat 310). In the utility model, the locking member 330 is connected to the main valve core 200, and the main valve core 200 can move to the first position and the second position as the locking member 330 switches between the initial position and the locked position, thereby satisfying the function of switching the water path. At the same time, during the process of switching the locking member 330 from the locked position to the initial position, when the locking member 330 moves to the unlocking position, it can trigger the pressure relief assembly to open the pressure relief channel through itself, the main valve core 200 or other components, thereby diverting part of the water in the valve cavity 101 to the outside of the valve cavity 101, thereby achieving the function of pressure relief, and water path switching and pressure relief can be achieved by pressing the sliding member 320, which is more convenient to operate.

[0055] It can be understood that in some embodiments of the present invention, the control component may also adopt other driving structures, such as configuring a main sliding key and a locking sliding key on the valve body 100, the main sliding key and the locking sliding key are configured with corresponding pin holes and pins, the main sliding key is connected to the main valve core 200, and after pushing the main sliding key to move the main valve core 200 to the second position, the locking sliding key slides to make the pin fit into the pin hole of the main sliding key, thereby locking the position of the main sliding key. When the locking sliding key is pushed in the reverse direction to make the pin withdraw from the pin hole, the backward action of the locking sliding key triggers the pressure relief component (such as pushing the pressure relief valve core) to open the pressure relief channel, thereby realizing the pressure relief function. At the same time, due to the action of the reset spring 340, the main sliding key and the main valve core 200 are reset to the first position, which can also meet the functions of water circuit switching and pressure relief.

[0056] like Figure 5 As shown, in some embodiments of the present invention, the pressure relief channel is arranged in the main valve core 200, and the pressure relief assembly includes a pressure relief valve core 410 movably arranged on the main valve core 200, and a pressure relief return spring 420 is arranged between the pressure relief valve core 410 and the sliding member 320 or the locking member 330 to be able to reset the pressure relief valve core 410 to a position that blocks the pressure relief channel, and the valve body 100 is provided with a top pressure structure, and the top pressure structure is arranged opposite to the pressure relief return spring 420. When the locking member 330 moves to the unlocking position, the top pressure structure pushes the pressure relief valve core 410 out of the position that blocks the pressure relief channel, thereby opening the pressure relief channel and meeting the pressure relief requirements.

[0057] Specifically, when the locking member 330 moves to the unlocking position, the main valve core 200 and the pressure relief valve core 410 (pushed and maintained in the blocking position by the pressure relief return spring 420) move accordingly. When the unlocking position is reached, the top pressure structure located on the valve body 100 (which has been in a relatively static state) presses the pressure relief valve core 410, causing the pressure relief valve core 410 to overcome the elastic force of the pressure relief return spring 420 and move out of the blocking position, thereby opening the pressure relief channel. When the main valve core 200 is moved to the first position by the return spring 340, the pressure relief valve core 410 is also driven to break away from the position matched with the top pressure structure. The pressure relief valve core 410 is pushed to the blocking position due to the elastic force of the pressure relief return spring 420, thereby closing the pressure relief channel.

[0058] like Figures 3 to 5 As shown, in some embodiments of the present invention, the pressure relief return spring 420 is disposed between the sliding member 320 and the pressure relief valve core 410 , which can meet the return and blocking requirements of the pressure relief valve core 410 .

[0059] Of course, in the specific implementation process, the pressure relief return spring 420 can be arranged between the locking member 330 and the pressure relief valve core 410, and can also meet the return and blocking requirements of the pressure relief valve core 410.

[0060] It is conceivable that in some embodiments of the present invention, the pressure relief channel may also be provided on the valve body 100, the pressure relief valve core 410 may be movably provided on the valve body 100, and the corresponding top pressure structure or driving structure may be provided on the main valve core 200 or the locking member 330. When the locking member 330 moves to the unlocking position, the top pressure structure or driving structure drives the pressure relief valve core 410 out of the blocking position, which may also meet the pressure relief requirements.

[0061] like Figure 5 As shown, in some embodiments of the present invention, the pressure relief channel communicates with the first water outlet 103 and the valve cavity 101 , so that part of the water in the valve cavity 101 can be discharged through the first water outlet 103 .

[0062] Of course, in the specific implementation process, the pressure relief channel can be configured to connect the valve cavity 101 with the outside of the valve body 100, which can also meet the pressure relief requirements.

[0063] like Figure 5As shown, in some embodiments of the utility model, the top pressure structure is a guide column 150 arranged in the valve body 100, a valve core through hole 201 for the guide column 150 to penetrate is provided in the main valve core 200, and the pressure relief valve core 410 is movably arranged in the valve core through hole 201, and there is a gap between the outer wall of the guide column 150 and the outer wall of the pressure relief valve core 410 and the inner wall of the valve core through hole 201 to form a pressure relief channel connecting the valve cavity 101 and the first water outlet 103. The pressure relief valve core 410 is provided with a pressure relief seal 411 capable of sealing the gap between the outer wall of the pressure relief valve core 410 and the inner wall of the valve core through hole 201. The pressure relief channel is sealed by the pressure relief seal 411. When the pressure relief valve core 410 moves and the pressure relief seal 411 moves away from the gap between the outer wall of the pressure relief valve core 410 and the inner wall of the valve core through hole 201, the pressure relief channel is opened, connecting the valve cavity 101 and the first water outlet 103, thereby achieving the pressure relief requirement.

[0064] Specifically, Figure 5 As shown, the valve body 100 includes a connecting body 110 and a water diversion body 120 that are interconnected, and a guide column 150 is arranged on the connecting body 110. The water in the valve cavity 101 enters the gap between the outer wall of the pressure relief valve core 410 and the inner wall of the valve core through hole 201 from the gap between the locking piece 330 and the main valve core 200, and finally enters the first water outlet 103 from the gap between the outer wall of the guide column 150 and the inner wall of the valve core through hole 201, thereby diverting the water in the valve cavity 101 to the first water outlet 103 for discharge.

[0065] It can be understood that in some embodiments of the present invention, a connecting channel can also be set in the main valve core 200, and the connecting channel connects the first water outlet 103, the gap between the outer wall of the pressure relief valve core 410 and the inner wall of the valve core through hole 201, and can also meet the function of pressure relief and water drainage. At this time, the gap between the outer wall of the guide column 150 and the inner wall of the valve core through hole 201 can be set to be smaller, and the guide column 150 can better guide the movement of the main valve core 200, thereby improving the position accuracy of the movement of the main valve core 200.

[0066] like Figures 3 to 8As shown, in some embodiments of the present invention, the sliding seat 310, the sliding member 320 and the locking member 330 are sequentially axially distributed, the sliding seat 310 is provided with a slide groove 311 for slidingly installing the sliding member 320, the inner wall of the slide groove 311 is provided with at least two convex ribs 312 at intervals, and a slideway 313 is formed between adjacent convex ribs 312, and a positioning inclined surface 314 is provided at one end of the convex rib 312 facing the locking member 330, and the sliding member 320 is provided corresponding to the slideway 313 and can slide in the slideway 313 The driving part 321 is movable, and a driving inclined surface 322 is arranged at one end of the driving part 321 facing the locking member 330. The locking member 330 can be partially or completely placed in the slide groove 311 and can rotate relative to the sliding seat 310. The locking member 330 is provided with a pressure-receiving part 331 corresponding to the slideway 313 and capable of sliding in the slideway 313. The pressure-receiving part 331 is provided with a pressure-receiving inclined surface 332 and a positioning groove 333 at one end facing the sliding member 320. The positioning groove 333 corresponds to the end of the rib 312 and can abut against each other.

[0067] When the sliding member 320 is pressed, the driving inclined surface 322 can press the pressed inclined surface 332 to make the locking member 330 rotate relative to the sliding seat 310, and at the same time push the locking member 330 to move axially. When the locking member 330 is pushed to the unlocking position,

[0068] The pressure-receiving portion 331 can be elastically pushed by the return spring 340 to slide into the slideway 313, so that the locking member 330 is reset to the initial position, or the pressure-receiving portion 331 can be elastically pushed by the return spring 340 to abut against the end of the rib 312, and the locking member 330 moves to the locking position.

[0069] When the locking rib 310 is in the unlocked position, the locking rib 330 is in the unlocked position and the pressing portion 331 is disengaged from the sliding path 313. The driving inclined surface 322 of the driving portion 321 presses against the pressing inclined surface 332 of the pressing portion 331 to rotate the locking rib 330 relative to the sliding seat 310, so that the locking rib 330 is rotated until the pressing portion 331 deviates from the sliding path 313. The locking rib 330 is reset by the reset spring 340 to move toward the sliding seat 310. The positioning inclined surface 314 cooperates with the positioning groove 333 to guide the end of the convex rib 312 to abut against the positioning groove 333, thereby The locking member 330 is positioned in the locking position, the main valve core 200 is in the second position, the sliding member 320 is pressed again, the pressure-bearing portion 331 is pushed away from the positioning groove 333, and the locking member 330 is pushed to the unlocking position. At the same time, the driving inclined surface 322 of the driving part 321 presses the pressure-bearing inclined surface 332 of the pressure-bearing portion 331 to rotate the locking member 330 relative to the sliding seat 310, so that the locking member 330 is rotated until the pressure-bearing portion 331 is aligned with the slideway 313, and the pressure-bearing portion 331 is elastically pushed by the return spring 340 to slide into the slideway 313, so that the locking member 330 returns to the initial position, and the main valve core 200 returns to the first position.
