The water outlet device 2000 according to an embodiment of the present invention may be a shower of a bathroom or a water outlet tap of a kitchen, for example, referring to fig. 1 and 2, the water outlet device 2000 is a shower, the shower includes a top spray 2100, a water outlet 2200 and a switch assembly 2300, two ends of the water outlet 2200 are respectively connected to the top spray 2100 and the switch assembly 2300, and water outlet or water shut off of the top spray 2100 can be controlled by the switch assembly 2300. In order to enable the top spray 2100 to discharge hot water more quickly when the top spray 2100 is next used, and reduce waiting time of a user, the drainage device 1000 of an embodiment of the present invention may be provided between the outlet pipe 2200 and the switch assembly 2300, and may drain excessive water in the outlet pipe 2200 when the top spray 2100 is closed. It should be noted that, the shower may further include a shower head, a shoulder spray, a waist spray, etc., and for convenience of explanation, the top spray 2100 is taken as an example in all the following embodiments.

Referring to fig. 3 and 4, in the embodiment of the present invention, the drainage device 1000 includes a housing 100, a mounting seat 200, a first piston 300, a first elastic member 310 and a blocking assembly 400, wherein the housing 100 is provided with a water passing cavity 110, a water inlet 120 and a water outlet 130 connected through the water passing cavity 110, the water inlet 120 is positioned at an upper end of the water passing cavity 110, and the water outlet 130 is positioned at a lower end of the water inlet cavity. For example, the housing 100 includes an upper end cap 101, a housing 102, and a lower end cap 103, the upper end cap 101 is formed with a water inlet 120 and connected to an upper end of the housing 102, the lower end cap 103 is formed with a water outlet 130 and connected to a lower end of the housing 102, a water passing cavity 110 is formed in the housing 102, and the water passing cavity 110 includes a water passing channel 140.

Referring to fig. 4, the mounting seat 200 is disposed in the water passing cavity 110, and a water passing channel 140 is formed between a sidewall of the mounting seat 200 and an inner wall of the water passing cavity 110, so that water flow can enter a space below the mounting seat 200 through the water passing channel 140 after passing through the water inlet 120, and finally water is discharged from the water outlet 130. The mounting seat 200 is provided with a first mounting cavity 210, the first piston 300 is slidably arranged in the first mounting cavity 210, and the first piston 300 can slide towards the bottom wall direction close to the first mounting cavity 210 under the action of water pressure during boiling water. The water pressure when boiled water refers to the water pressure when the switch assembly 2300 is opened, so that the water outlet pipe 2200 is filled with water.

The first elastic member 310 may be a spring, a rubber member having elasticity, a silicone member, or the like, and the first elastic member 310 is disposed in the first installation cavity 210 and connected to the first piston 300, for example, the first elastic member 310 is located between the first piston 300 and the bottom wall of the first installation cavity 210. The first elastic member 310 is configured to provide an elastic force to the first piston 300 that moves in a direction away from the bottom wall of the first installation cavity 210, and the elastic force provided by the first elastic member 310 is greater than the force of the water pressure on the first piston 300 when water is shut off. The water pressure at the time of closing refers to the pressure generated by the water in the outlet pipe 2200 under its own weight when the switch assembly 2300 is closed. The closure assembly 400 comprises a closure portion 410, the closure portion 410 being capable of opening or closing the water outlet 130 under the influence of the first piston 300.

It will be appreciated that, referring to fig. 5, the dashed arrows in fig. 5 indicate the flow direction of water, and the dashed arrows in other drawings are the same and will not be described again. When the switch assembly 2300 is opened to discharge water from the top spray 2100, a major portion of the water is discharged through the top spray 2100 and a minor portion of the water is introduced into the water chamber 110 through the water inlet 120. At this time, the water pressure in the outlet pipe 2200 is large, and the first piston 300 moves toward the bottom wall of the first installation cavity 210 under the action of the water pressure, so that the first piston 300 compresses the first elastic member 310, and the blocking portion 410 keeps blocking the outlet 130. I.e., top spray 2100, the drain 1000 does not continue to discharge water.

When the switch assembly 2300 closes the top spray 2100, referring to fig. 7, the water pressure in the water passing chamber 110 is reduced, and is smaller than the elastic force of the first elastic member 310, the first elastic member 310 pushes the first piston 300 to move in a direction away from the bottom wall of the first installation cavity 210, and simultaneously the first piston 300 can drive the blocking portion 410 to move when moving, so that the blocking portion 410 opens the water outlet 130. Thus, the water in the water outlet pipe 2200 is discharged through the water outlet 130, and the hot water can be discharged at a faster rate when the top spray 2100 is next used.

By adopting the scheme, the water in the water pipe 2200 can be automatically released by the water drainage device 1000, a mobile power supply or a power adapter is not needed, and operations such as battery replacement or strong electricity connection are not needed, so that the safety and the use convenience can be improved, and the use experience of a user is good. After the residual water in the water pipe 2200 is released, the situation that bacteria are greatly bred and the health of users is affected due to long-time water storage can be reduced.

Referring to fig. 5, in the embodiment of the present invention, the plugging assembly 400 further includes a connecting member 420, wherein one end of the connecting member 420 is disposed in the first installation cavity 210 in a penetrating manner and is fixedly connected with one end of the first piston 300, and the other end of the connecting member 420 is disposed in the first installation cavity 210 in a penetrating manner and is connected with the plugging portion 410. When the first piston 300 moves, the connecting piece 420 can be driven to move, so that the blocking part 410 is controlled to open or close the water outlet 130 through the connecting piece 420.

Since the user is in the process of showering, there may be multiple on-off top sprays 2100 or a shorter interval between showers. If the top spray 2100 is closed each time, the water drain device 1000 directly drains water, so that each time the top spray 2100 is opened, water is required to refill the water outlet pipe 2200, resulting in a slow water outlet speed of the top spray 2100, which may affect the user experience. Thus, a delayed drainage may be designed to ameliorate the above problems.

For example, referring to fig. 5, in the embodiment of the present invention, the first piston 300 has a sealing portion 301, and the sealing portion 301 is provided with a sealing ring so as to be in sealing engagement with the inner wall of the first mounting chamber 210. Along the movement direction of the first piston 300, both ends of the sealing part 301 divide the first mounting chamber 210 into a first sealing chamber 320 and a second sealing chamber 330, and the first sealing chamber 320 is located above the second sealing chamber 330. And the first seal chamber 320, the second seal chamber 330 and the water passing chamber 110 are blocked, i.e., the first seal chamber 320 and the second seal chamber 330 are not communicated with the water passing chamber 110. The first seal chamber 320 and the second seal chamber 330 are filled with a liquid, which may be water, oil, or the like. The first piston 300 is provided with a second installation cavity 340 therein, and the connecting member 420 is provided with a first communication port 421. The drainage device 1000 further includes a second elastic member 510 and a second piston 500 slidably disposed in the second installation cavity 340, and the second piston 500 can close the first communication port 421 under the elastic force of the second elastic member 510. And the second piston 500 is provided with a second communication port 520, and the flow area of the second communication port 520 is smaller than that of the first communication port 421. The second elastic member 510 may be a spring, a rubber member having elasticity, a silicone member, or the like.

Wherein the first piston 300 has a first position and a second position, the positions being shown in fig. 5 when the first piston 300 is moved to the first position in a direction approaching the bottom wall of the first mounting chamber 210. I.e., the first piston 300 moves downward by the water pressure such that the volume of the first sealing chamber 320 increases and the volume of the second sealing chamber 330 decreases. Referring to fig. 6, since the first and second seal chambers 320 and 330 are filled with liquid, the liquid in the second seal chamber 330 overcomes the elastic force of the second elastic member 510 to push up the second piston 500 and enters the first seal chamber 320 through the first communication port 421.

When the first piston 300 moves to the second position in a direction away from the bottom wall of the first mounting chamber 210, the position shown in fig. 7, i.e., the first piston 300 moves upward under the elastic force of the first elastic member 310, the second position is above the first position. At this time, the volume of the first seal chamber 320 is reduced, and the volume of the second seal chamber 330 is increased. Referring to fig. 8, since the force of the liquid acting on the second piston 500 and the elastic force of the second elastic member 510 are downward, the second piston 500 seals the first communication port 421, i.e., the liquid in the first sealing chamber 320 needs to flow back to the second sealing chamber 330 through the second communication port 520. But the flow area of the second communication port 520 is smaller than that of the first communication port 421 so that the upward moving speed of the first piston 300 is smaller than that of the downward moving speed. That is, when the first piston 300 moves upward, the excessive liquid in the first seal chamber 320 needs to be squeezed into the second seal chamber 330 to move, and the upward movement speed of the first piston 300 can be affected by providing different sizes of the second communication ports 520.

For example, when the top spray 2100 is opened to discharge water, the first piston 300 moves downward by the water pressure. When the top spray 2100 is closed Shui Shi, the first piston 300 needs to move upwards by 5mm, and then the blocking part 410 can open the water outlet 130 to drain water; while the first piston 300 is positioned between 0mm and 5mm, the closure portion 410 is always in sealing engagement with the outlet 130, such as a sliding seal. By properly sizing the second communication port 520, the time required for the first piston 300 to move up by 5mm is one hour. I.e., top spray 2100 turns off water for one hour, drain 1000 will drain water from outlet pipe 2200. And after one hour, the water temperature in outlet pipe 2200 drops to a temperature close to the ambient temperature, and water in outlet pipe 2200 is discharged at this time so that hot water is rapidly discharged at the next time of water consumption. The situation that the water outlet pipe 2200 needs to be refilled each time when a short-time shower is performed can be avoided, waiting time of a user is shortened, and use experience of the user is improved.

Because the water temperature in the outlet pipe 2200 is decreased at different room temperatures, the upward moving speed of the first piston 300 can be changed by adjusting the flow area of the second communication port 520, thereby meeting the use requirements under different conditions.

In order to enable the flow area of the second communication port 520 to be adjustable, referring to fig. 4 and 7, in the embodiment of the present invention, the drainage device 1000 includes an adjusting assembly 600, and the adjusting assembly 600 is connected to the second piston 500, and the adjusting assembly 600 is used for changing the flow area of the second communication port 520, so as to adjust the rising speed of the first piston 300, thereby meeting the use requirements under different conditions. For example, the adjusting assembly 600 includes an adjusting member 610, the adjusting member 610 is screwed with the second piston 500, the lower end of the adjusting member 610 is spherical or conical, and the lower end of the adjusting member 610 is disposed toward the second communication port 520. Through rotatory regulating part 610 for regulating part 610 can be along being close to or keep away from the relative position of second communication port 520 regulation and second piston 500, and the relative position of one end of regulating part 610 and second communication port 520 is different promptly, can change the flow area of second communication port 520 to adjust the speed that first piston 300 risees, satisfy the different user demand of user.

Referring to fig. 6, in another embodiment of the present invention, the adjusting assembly 600 may further include an adjusting member 610, a ball 620, and a third elastic member 630, wherein the third elastic member 630 is disposed in the second communication port 520, and the third elastic member 630 may be a spring, a silicone member having elasticity, a rubber member, or the like. The adjusting member 610 is in threaded connection with the second piston 500, a groove in limit fit with the ball 620 is formed at one end of the adjusting member 610 facing the second communication port 520, the ball 620 is connected with the third elastic member 630 and located between the adjusting member 610 and the third elastic member 630, and an arc surface matched with the ball 620 is formed at the inlet end of the second communication port 520. By rotating the adjusting member 610, the adjusting member 610 is enabled to adjust the relative position with the second piston 500 in a direction approaching or separating from the second communication port 520, thereby changing the size of the gap between the ball 620 and the second communication port 520 to adjust the flow area of the second communication port 520. The third elastic element 630 enables the ball 620 to be always located in the groove of the adjusting element 610, so as to avoid the situation that the ball 620 is dislocated and separated from the groove.

It can be appreciated that, by adopting the scheme of the sphere 620, the flow area of the second communication port 520 can be effectively changed, for example, the flow area of the second communication port 520 is linearly changed. When the adjusting member 610 drives the ball 620 to approach the second communication port 520, the flow area of the second communication port 520 is reduced, and the upward movement speed of the first piston 300 is reduced, i.e. the drainage device 1000 will drain after a longer time; when the adjusting member 610 moves in a direction away from the second communication port 520, the ball 620 also moves in a direction away from the second communication port 520 under the elastic force of the third elastic member 630, so that the flow area of the second communication port 520 increases, the upward movement speed of the first piston 300 increases, and the time required for draining the water by the drainage device 1000 decreases.

Referring to fig. 7, in the embodiment of the present invention, the drainage device 1000 further includes a sealing head 220, and the sealing head 220 is connected to an end of the first piston 300 near the water inlet 120, that is, an upper end of the first piston 300, to close an end of the second installation cavity 340. The seal head 220 and the first piston 300 are connected in a detachable manner, such as a threaded connection or a clamping connection. The seal head 220 is internally provided with the limiting cavity 221, the second elastic piece 510 is arranged in the limiting cavity 221, the limiting cavity 221 plays a role in limiting the position of the second elastic piece 510 and guiding, and the conditions of deflection, dislocation and the like of the position of the second elastic piece 510 are avoided. It can be appreciated that when the flow area of the second communication port 520 needs to be adjusted, the sealing head 220 and the upper end cover 101 can be disassembled, so that the head of the adjusting member 610 is exposed from the opening of the second mounting cavity 340, and the adjusting member 610 can be rotated by a tool such as a screwdriver to adjust the flow area of the second communication port 520.

With continued reference to fig. 7, in the embodiment of the present invention, the connecting member 420 is provided with a third installation cavity 422, a fourth elastic member 430 is disposed in the third installation cavity 422, and the upper end of the blocking portion 410 is slidably disposed in the third installation cavity 422 and connected to the fourth elastic member 430. The fourth elastic member 430 is configured to provide an elastic force for closing the water outlet 130 to the blocking portion 410, that is, the blocking portion 410 can close the water outlet 130 under the elastic force of the fourth elastic member 430, so that the tightness of the blocking portion 410 when closing the water outlet 130 can be improved, and the water leakage and seepage situation can be reduced. The fourth elastic member 430 may be a spring, a silicone member, a rubber member, or the like.

In order to enable the first piston 300 to drive the blocking portion 410 to open the water outlet 130, referring to fig. 7 and 10, in the embodiment of the invention, a clamping structure 440 is disposed on an outer wall of the connecting member 420, the clamping structure 440 includes a clamping pin 441, a protruding portion 411 is disposed on an outer side wall of the blocking portion 410, and a clamping portion 4412 of the clamping pin 441 can be clamped with the protruding portion 411, so as to drive the blocking portion 410 to move and open the water outlet 130. For example, when the first piston 300 moves upward, the locking pin 441 can be driven to move synchronously, and during the movement of the locking pin 441, the locking portion 4412 is locked with the protruding portion 411 of the blocking portion 410, so as to drive the blocking portion 410 to move upward together, and finally open the water outlet 130. By adopting the clamping structure 440, the blocking portion 410 can be effectively driven to move, and the success rate of the blocking portion 410 when the water outlet 130 is opened is improved.

In another embodiment, in order to enable the first piston 300 to drive the blocking portion 410 to open the water outlet 130, a first protrusion may be disposed on a side wall of the blocking portion 410 located in the third installation cavity 422, and a second protrusion is disposed on an inner wall of the third installation cavity 422, which is not shown in the scheme. When the blocking portion 410 closes the water outlet 130, the first protrusion and the second protrusion are separated; when the first piston 300 moves upward and synchronously drives the connecting piece 420 to move upward, the first protrusion and the second protrusion are abutted, so that the blocking portion 410 is driven to move upward to open the water outlet 130, and a proper scheme is selected according to practical situations.

Referring to fig. 9 and 10, in the embodiment of the present invention, the locking structure 440 further includes a connection base 442, where the connection base 442 is fixedly connected to the connection member 420, and the connection base 442 is formed with a fourth mounting cavity 443 for mounting the locking pin 441. When the first piston 300 moves downward to the first position, as shown in fig. 5, the catching portion 4412 of the catch 441 is separated from the protruding portion 411, and the blocking portion 410 closes the water outlet 130. When the first piston 300 moves upward to the second position, as shown in fig. 7, in the process of moving the first piston 300, the connecting piece 420 and the connecting seat 442 drive the bayonet 441 to move upward, so that the clamping portion 4412 and the protruding portion 411 are clamped and drive the blocking portion 410 to move upward together, and further the water outlet 130 is opened to drain the excessive water in the water outlet pipe 2200.

It can be appreciated that when the blocking portion 410 is in a state of opening the water outlet 130, if the blocking portion 410 is required to re-close the water outlet 130, the first piston 300 drives the blocking portion 410 to re-block the water outlet 130 through the connecting piece 420 under the action of the water pressure during the boiled water. However, in this process, the water outlet 130 needs to be closed after a certain period of time.

In order to automatically close the water outlet 130 after the blocking portion 410 is drained so that the water outlet 130 does not directly discharge water when the switch assembly 2300 is opened next time, referring to fig. 9 and 10, in the embodiment of the present invention, the lower end of the mounting base 200 is provided with the pushing portion 231, the latch 441 is provided with the guiding inclined surface 4411, the latch structure 440 further includes a fifth elastic member 444, which may be a spring, a silicone member, a rubber member, or the like, and the fifth elastic member 444 is configured to provide an elastic force to the latch 441 to move along the sidewall adjacent to the blocking portion 410.

The first piston 300 also has a third position, which is located on a side of the second position remote from the first position, i.e. above the second position. When the first piston 300 moves from the second position to the third position, the guide inclined surface 4411 abuts against the pushing portion 231, so that the blocking pin 441 moves in a direction away from the blocking portion 410, the blocking portion 410 moves downward and blocks the water outlet 130 under the elastic force of the fourth elastic member 430 after the restriction of the blocking pin 441 is lost by separating the blocking pin 441 from the protruding portion 411. When the water outlet 130 is plugged again, the situation that the water outlet 130 directly discharges water when the switch assembly 2300 is opened next time can be effectively reduced. By utilizing the cooperation of the guide inclined plane 4411 and the pushing part 231, manual control by a user is not needed, electric control is not needed, the convenience of use can be improved, strong electricity is not needed to be connected, and the safety is ensured.

For example, the movable stroke of the first piston 300 is 7mm or more, starting from the first position of the first piston 300, and when the upward movement distance of the first piston 300 is within 5mm, the blocking portion 410 keeps blocking the water outlet 130 all the time, and the blocking time is about one hour, so as to realize delayed drainage. When the first piston 300 continues to move upwards by a distance of more than 5mm and less than 7mm, the clamping pin 441 and the protruding portion 411 are clamped, so that the blocking portion 410 is driven to move and the water outlet 130 is opened. When the first piston 300 moves upward by a distance equal to or greater than 7mm, the blocking pin 441 moves in a direction away from the blocking portion 410 by the cooperation of the pushing portion 231 and the guide inclined surface 4411, so that the blocking portion 4412 and the protruding portion 411 are separated, and the blocking portion 410 re-blocks the water outlet 130 under the elastic force of the fourth elastic member 430. The time required for the first piston 300 to move from 5mm to 7mm is about 20 minutes, so that most of the water in the outlet pipe 2200 can be surely discharged, and the water outlet 130 is prevented from being closed when the water in the outlet pipe 2200 starts to be discharged. By adopting the scheme that the adjusting piece 610 is used for adjusting the flow area of the second communication port 520, the time required for the first piston 300 to move from 5mm to 7mm can be adjusted, so that the water storage amount of the water outlet pipe 2200 can be adjusted adaptively.

With continued reference to fig. 9, in an embodiment of the present invention, the mounting base 200 further includes a positioning portion 240, and when the first piston 300 and the positioning portion 240 remain in abutment, the first piston 300 is no longer lifted. The positioning portion 240 is used for limiting the position of the first piston 300, so as to play a role in positioning and prevent the first piston 300 from being separated from the first mounting cavity 210 under the elastic force of the first elastic member 310.

Referring to fig. 9, in the embodiment of the present invention, a sleeve 230 is disposed at the lower end of the mounting seat 200, the sleeve 230 is disposed through the bottom wall of the first mounting cavity 210, a portion of the side wall of the sleeve 230 forms a pushing portion 231, and an inclined surface matching with the guiding inclined surface 4411 is disposed at the outer side of the lower end of the pushing portion 231. The connecting piece 420 is arranged in the inner cavity of the sleeve 230 in a penetrating manner and is sealed with the inner cavity in a sliding manner, so that the connecting piece 420 can always keep the water passing cavity 110 and the second sealing cavity 330 in a separated state in the axial direction of the sleeve 230, and liquid in the second sealing cavity 330 is prevented from entering the water passing cavity 110.

Referring to fig. 1 and 2, in the embodiment of the present invention, the drainage device 1000 further includes an adapter 700, and the adapter 700 includes a first pipe section 710 and a second pipe section 720, wherein the first pipe section 710 is connected between the outlet pipe 2200 and the switch assembly 2300, and both ends of the second pipe section 720 are respectively connected with the sidewall of the first pipe section 710 and the water inlet 120. By adopting the scheme of the adapter 700, the original structure of the shower does not need to be changed too much, and the adapter 700 is connected between the water outlet pipe 2200 and the switch assembly 2300, so that the shower is flexible to install, convenient and quick to use and high in adaptability. For example, a drain 1000 may be installed between the outlet pipe 2200 of the top shower 2100, the shower head, the waist shower head, etc., and the switch assembly 2300.

The water outlet device 2000 according to an embodiment of the present invention includes the drainage device 1000 according to any one or more of the above embodiments, and the water outlet device 2000 may be a shower device, a kitchen faucet, or the like. With the water outlet device 2000 of the embodiment of the present invention, when the water outlet device 2000 is used for discharging water, a part of water enters the water passing cavity 110 from the water inlet 120 of the housing 100, under the action of water pressure, the first piston 300 can be pushed to slide along the direction close to the bottom wall of the first installation cavity 210 of the installation seat 200 and compress the first elastic member 310, and the first piston 300 can drive the blocking portion 410 of the blocking assembly 400 to move so as to block the water outlet 130, that is, when the water outlet device 2000 is used for discharging water, the water outlet device 1000 can not continuously discharge water. When the water outlet device 2000 is turned off, the water pressure in the water passing cavity 110 is reduced, and is smaller than the elastic force of the first elastic member 310, the first piston 300 can move in a direction away from the bottom wall of the first installation cavity 210 under the elastic force of the first elastic member 310, so as to drive the blocking portion 410 to move to open the water outlet 130, and drain the excessive water in the water outlet pipe 2200. Therefore, the drain device 1000 does not need to adopt a mobile power supply or a power adapter, does not need to replace a battery or connect with a strong current, and the like, can improve safety and convenience of use, and has better use experience for users.
