TECHNICAL FIELD

[0001] The utility model relates to the bathroom technical field, specifically, relates to a water outlet structure of quick water stop and shower thereof. BACKGROUND

[0002] In prior art, shower such as shower head, for example, top spray shower head, handheld shower, etc., after closing water outlet, a certain amount of water remains in the shower head, thus producing residual water drop leakage phenomenon, which not only wastes water resources but also affects customer experience.

[0003] To solve the problem, the existing shower that closes and stops immediately usually adopts water blocking design, when water flow is opened, the water blocking plate is moved upward under the action of water pressure and is lifted, realizing water outlet of the shower, when water flow is closed, the water blocking plate resets, realizing automatic water stop function.

[0004] However, since the water blocking plate has a certain weight, it needs to be lifted, and before water flows through the shower to the real water outlet of the shower, the water needs to be pressurized in the pressure chamber for a period of time to form sufficient buoyancy, so it has the defects of high starting water pressure and delayed water outlet. Therefore, it is urgent to provide a more novel and ingenious water stop design. SUMMARY

[0005] Therefore, the utility model aims at providing a water outlet structure of quick water stop and shower thereof to solve the above problems.

[0006] The utility model adopts the following scheme:

[0007] The application provides a water outlet structure of quick water stop, which comprises a water inlet end, a water channel and a water outlet end. The water channel is provided with a switch assembly, the switch assembly is controlled by water pressure, and the switch assembly is opened to connect the water inlet end and the water outlet end when water flows in the water inlet end, and the switch assembly is closed to close the water inlet end and the water outlet end when water flow in the water inlet end is cut off. The water outlet structure further comprises an internal chamber, the internal chamber is connected with the water outlet end, and the chamber is relatively closed and forms negative pressure after the switch assembly is closed. The switch assembly at least comprises a guide member. The guide member has a water inlet state of moving to a first position under the action of water pressure to open the switch assembly, a water cut-off state of resetting and moving upward to a second position to close the switch assembly after the pressure is released, and an air extraction state of continuing to reset and moving upward to a third position to extract air in the chamber to form negative pressure.

[0008] As a further improvement, the guide member comprises a seat body, a movable rod and a spring; the seat body is controlled to move relatively along the up and down direction of the water inlet under the action of water pressure; the movable rod is in linkage with the seat body; the spring is abutted below the seat body to keep the seat body and the movable rod at the third position when there is no water inflow; wherein, one side of the water outlet end is provided with a limiting member for quickly limiting the seat body to move downward to the first position, and the spring is abutted between the limiting member and the seat body; one side of the water inlet end is provided with a guide cylinder which is in plug-in fitting with the movable rod, and after moving to the second position, the movable rod is in contact with the guide cylinder to block the water flow entering the water inlet end along the guide cylinder, and after moving to the third position, the movable rod is in plug-in fitting in the guide cylinder.

[0010] As a further improvement, the delay member comprises a piston member movably clamped on the seat body and a reset member abutted below the piston member; the piston member and the seat body have a stroke allowance therebetween to enable the upward movement of the piston member after the seat body.

[0011] As a further improvement, the reset member shares the same limiting member with the spring, and the elastic force of the reset member is smaller than that of the spring, and after the pressure is released, the spring drives the seat body to quickly rebound to the second position and the third position.

[0012] As a further improvement, after the seat body rebounds to the second position or the third position, the reset member drives the piston member to rebound to the reset state immediately.

[0014] As a further improvement, opposite sides of the seat body are respectively provided with a bayonet fitting adapted to the respective piston member, and the body of the piston member is correspondingly provided with a lower flange and an upper flange; when moving under the action of water pressure, the bayonet fitting is abutted on the lower flange to enable the synchronous movement of the two, and after the pressure is released, due to the faster reset speed of the seat body than that of the piston member, the bayonet fitting moves relatively towards the upper flange to reduce the relative allowance therebetween.

[0015] As a further improvement, after the seat body moves to the third position, the reset member drives the piston member to delay moving to the reset state, and at this time, the lower flange is clamped on the bayonet fitting.

[0016] As a further improvement, a sealing member is arranged at the water outlet end to cooperate with the water outlet; the sealing member is configured to swing to a contracted state to avoid the water outlet under water flow, and to return to an expanded state to block the water outlet and cooperate with the guide member to seal the internal chamber under water cut-off.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment. Obviously, the described embodiment is a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model.

[0030] EMBODIMENT

[0031] In combination with Figures 1 to 6 , the embodiment provides a water outlet structure of quick water stop, which comprises a water inlet end 1, a water channel (such as Figure 1 the direction of the dashed arrow), and a water outlet end 2. The water channel is provided with a switch assembly 3, and the switch assembly 3 is controlled by water pressure, and is opened to connect the water inlet end 1 and the water outlet end 2 when water flows in the water inlet end 1, and is closed to close the water inlet end 1 and the water outlet end 2 when water stops flowing in the water inlet end 1.

[0032] The water outlet structure further comprises an internal chamber, and the internal chamber is in communication with the water outlet end 2. After the switch assembly 3 is closed, the chamber is relatively airtight and forms a negative pressure.

[0033] The switch assembly 3 at least includes a guide member 31. The guide member 31 has a water pressure-affected first position to open the switch assembly 3, a water pressure-removed second position to close the switch assembly 3, and a third position to extract air in the chamber to form a negative pressure.

[0034] The above-mentioned quick water-stopping water outlet structure, when the water inlet end 1 is connected to the water outlet end 2 for water supply, the switch assembly 3 is quickly opened to connect the water inlet end 1 and the water outlet end 2 for water supply, and when the water inlet end 1 is disconnected from the water outlet end 2, the switch assembly 3 is quickly closed to make the internal chamber relatively airtight and form a negative pressure, so that the water outlet end 2 connected to the internal chamber can be stopped immediately, and the residual water droplets in the water outlet end 2 are not leaked, especially, the guide member 31 of the switch assembly 3 can switch between the first position, the second position and the third position, corresponding to the first position after being affected by the water pressure, the water flow channel is opened to connect the water inlet end 1 and the water outlet end 2, corresponding to the second position after being reset to the upper position after the water pressure is removed, the water inlet end 1 and the water outlet end 2 are blocked and the internal chamber is kept relatively airtight, and after the guide member 31 is continuously reset to the third position, air in the chamber is extracted to form a negative pressure, so that the water outlet end 2 is quickly stopped in the air extraction state.

[0035] Therefore, the guide member 31 of the switch assembly 3 realizes the quick water-stopping function, avoids the phenomenon of water droplet leakage after the water flow of the shower device such as a shower head is closed, and thus not only saves water but also significantly improves the user's experience and reduces the problem of water stains and water droplet residues. The three-stage switching of the up-and-down movement of the guide member 31 not only improves the efficiency of the switch switching, but also ensures the accuracy and reliability of each operation stage, and provides the user with a more environmentally friendly, water-saving and comfortable use experience.

[0036] As shown in the figure, in the embodiment, the guide member 31 includes a seat body 311, a movable rod 312 and a spring 313. The seat body 311 is relatively guided to move in the up-and-down direction of the water inlet under the action of water pressure, the movable rod 312 is linked with the seat body 311, and the spring 313 abuts below the seat body 311 to keep the seat body 311 and the movable rod 312 at the third position when there is no water.

[0037] The water outlet end 2 is provided with a limiting member 21 for quickly limiting the seat 311 to move downward to the first position, and the elastic member 313 is abutted between the limiting member 21 and the seat 311. The water inlet end 1 is provided with a guide cylinder 11 which is adapted to the movable rod 312, and after moving to the second position, the movable rod 312 is in contact with the guide cylinder 11 to block the water flow along the guide cylinder 11 into the water inlet end 1, and after moving to the third position, the movable rod 312 is inserted into the guide cylinder 11.

[0038] In the above, the seat 311 is guided to move up and down by the water pressure, so that the movement of the seat 311 is accurately controlled, and the multi-stage operation can be realized, from boiling water to cutting off water, and then to the state transformation of negative pressure water stop. The elastic member 313 is abutted below the seat 311, and the purpose is to keep the seat 311 and the movable rod 312 at the third position until the water flow is opened. In the absence of water pressure, the seat 311 is kept at the default initial position, which ensures the reliable start of the structure and prevents accidental opening in the absence of water flow.

[0039] In addition, the limiting member 21 is arranged on the water outlet end 2 side to quickly limit the seat 311 to move downward to the first position, which ensures that the seat 311 will not move excessively due to water pressure fluctuations or other factors, and helps to accurately control the opening and closing operation. The guide cylinder 11 is arranged on the water inlet end 1 side and is adapted to the movable rod 312, which ensures the accurate movement of the movable rod 312. The guide cylinder 11 ensures the effective blocking or opening of the water flow in the water passage through the in-out movement of the movable rod 312. When moving to the third position, the movable rod 312 is completely inserted into the guide cylinder 11, and the movable rod 312 and the guide cylinder 11 form a piston type plug-in cooperation, which ensures that the air in the chamber is further removed.

[0040] As Figures 2 to 6As shown, in the present embodiment, the switch assembly 3 further comprises a delay component 32. The delay component 32 is capable of moving synchronously with the seat body 311 to the first position, and when the guide component 31 is reset to move to the second position or the third position, the delay component 32 is configured to delay the reset and further implement the extraction of air in the cavity to form another negative pressure superimposed. Thus, through the mutual cooperation between the guide component 31 and the delay component 32, when the guide component 31 is reset to the second position or the third position, the delay component 32 continues to remain in the original position for a period of time, and such a delay action will promote the further enhancement of the negative pressure in the cavity to form a superimposed negative pressure. The superimposed negative pressure effect can more effectively prevent water flow from remaining in the water outlet 2 after stopping or even dripping, thereby further reducing water dripping phenomenon and water resource waste, especially after the water flow is turned off, the residual water will be avoided from accumulating water droplets by the negative pressure effect. The delay component 32 can remain in the original position when the guide component 31 component is reset, delay its own reset process, and ensure that after the water flow is turned off, the air extraction state of the guide component 31 is executed, and through the further air extraction operation of the delay component 32 which is not too abrupt again, the negative pressure can be maintained for a certain period of time again, further enhancing the water stopping effect.

[0041] Specifically, the delay component 32 comprises a piston piece 321 movably clamped on the seat body 311, and a reset piece 322 abutting below the piston piece 321. The piston piece 321 and the seat body 311 have a stroke allowance therebetween to enable the upward movement of the piston piece 321 to lag behind the movement of the seat body 311. Thus, when the water flow is turned off, the movement of the piston piece 321 will lag behind the movement of the seat body 311, ensuring that the seat body 311 and the piston piece 321 will not reset at the same time. Such a lagging movement enables the piston piece 321 to apply an additional air extraction operation at the appropriate time, further enhancing the negative pressure effect in the cavity. It should be noted that the stroke allowance enables the reset actions of the seat body 311 and the piston piece 321 to be not completely synchronized, thereby making the effect of the delay reset more obvious. Through the lagging movement brought by the stroke allowance, the piston piece 321 can continue to apply pressure during the air gap period after the water flow is turned off, thereby increasing the negative pressure in the cavity and effectively providing negative pressure to the water outlet 2, making the negative pressure superimposed effect more continuous, the water stopping effect is also improved, and the water dripping phenomenon is completely inhibited.

[0042] It should be noted that the piston 321 can be achieved by adapting the breathing valve (not shown) used for exhaust, corresponding to the reset member 322 driven piston 321 reset movement, the chamber gas is discharged through the breathing valve, and when under pressure, the breathing valve is used to access the air into the chamber, so as to realize the piston reciprocating exhaust. And, the movable rod 312 of the guide member 31 is inserted into the guide cylinder 11, corresponding to the preliminary extraction of air in the chamber to form a negative pressure, which can at least ensure that the water in the water outlet 2 is kept from dripping. The lagging piston 321 again performs secondary extraction of air in the chamber to form a superimposed negative pressure, which can keep the water in the water outlet 2, and even can flow away from the water outlet 2.

[0043] Wherein, the reset member 322 and the elastic member 313 share the same limit member 21, and the elastic force of the reset member 322 is less than the elastic force of the elastic member 313. After the pressure is released, the elastic member 313 drives the seat 311 to quickly rebound to the second position and the third position. Preferably, after the seat 311 rebounds to the second position, the movable rod 312 is blocked with the guide cylinder 11, so that the chamber is at least closed at the top (corresponding to the lower part blocked by the sealing member 33 below), and after the seat 311 switches to the second position, the reset member 322 drives the piston 321 to reset and extract air.

[0044] Wherein, after the seat 311 rebounds to the second position or the third position, the reset member 322 drives the piston 321 to rebound to the reset state immediately. Obviously, after the piston 321 rebounds, it can at least extract air in the chamber. It can be understood that the piston 321 is movably inserted in the internal chamber and is coupled to the outside by the piston type. After the reset movement, the piston 321 extracts air in the chamber to the outside.

[0045] Further, the opposite sides of the seat 311 are respectively provided with the bayonet 314 adapted to the respective piston 321. The body of the piston 321 is correspondingly provided with the lower flange 323 and the upper flange 324. When the water pressure is removed, the bayonet 314 is abutted on the lower flange 323 to make the two synchronous movement. After the pressure is removed, because the reset speed of the seat 311 is faster than that of the piston 321, the bayonet 314 moves relatively towards the upper flange 324, so that the relative amount between the two is reduced. And, after the seat 311 moves to the third position, the reset member 322 drives the piston 321 to delay to the reset state, and at this time, the lower flange 323 is clamped on the bayonet 314.

[0046] When the water is on, the seat body 311 is pushed down by the water pressure, the bayonet 314 is in abutment with the lower flange 323 to drive the piston piece 321 to move together, ensuring the accuracy of synchronous movement. When the water is off, the pressure is released, the seat body 311 and the bayonet 314 move relatively towards the upper flange 324 until they reach the second position or the third position, at which time the reset piece 322 drives the piston piece 321 to reset and move until the lower flange 323 abuts the bayonet 314, which are limited and cooperated with each other and prepare for the next stage of synchronous movement.

[0047] As shown in Figure 2 , Figure 7 and Figure 8 , in the present embodiment, the water outlet end 2 is further provided with a sealing member 33 cooperating with the water outlet. The sealing member 33 is configured to swing to a contracted state to avoid the water outlet when the water is on, and reset to an expanded state to block the water outlet and cooperate with the guide member 31 to close the internal chamber when the water is off. Therefore, by configuring the sealing member 33 on the water outlet end 2, it automatically contracts when the water is on, and automatically resets to expand and block the water outlet after the water is off, so as to cooperate with the guide member 31 to reset to the second position, thereby achieving the upper and lower sealing of the chamber, effectively improving the water stopping effect and sealing performance. The adaptive switching state of the sealing member 33 can quickly respond to the water on and off, not only ensuring the accuracy of water flow control, but also avoiding residual water leakage and water retention.

[0048] Further, the sealing member 33 includes a silica gel sheet 331. The cross section of the silica gel sheet 331 is spread in a figure-eight shape to contain and support the circumference of the water outlet hole of the water outlet end 2. After the water is on, the water flow corresponds to press the silica gel sheet 331 to avoid the water outlet passage downward, and after the water is off, the silica gel sheet 331 resets to the initial state to block the water outlet hole. After the guide member 31 moves to the second position, the two cooperate with each other to relatively close the internal chamber, thereby facilitating the subsequent disengagement of the guide member 31 and the delay member 32 from the air.

[0049] In combination with Figure 7 and Figure 8 , the present embodiment further provides a shower, which includes a shower body 4 and a quick water stopping water outlet structure configured in the shower body 4. The shower body 4 is provided with a water inlet connector 5 forming the water inlet end 1, a water outlet panel 6 forming the water outlet end 2, and the waterway channel and the internal chamber are correspondingly formed in the shower body 4.

[0050] It can be understood that the shower body 4 is specifically a top spray shower piece (as shown in Figure 1 ), a handheld shower piece (as shown in Figure 7 ) and the like, which is used for users to shower.

[0051] The above are only preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical scheme falling within the concept of the present application belongs to the protection scope of the present application.
