Description

Technical Field

[0001] The present invention relates to the technical field of bathrooms, and in particular to a water outlet structure capable of being turned on and off immediately and a shower device thereof. Background Art

[0002] In the prior art, shower heads and other showerheads, such as overhead shower heads and handheld shower heads, still have a certain amount of water remaining in the shower head after the water flow is turned off, thereby causing residual water dripping, which not only wastes water resources but also affects the customer experience.

[0003] To solve this problem, existing instant-on stop shower heads usually adopt a water-blocking design. When the water flow is turned on, the water baffle moves upward under the action of water pressure and is lifted up, allowing the shower head to discharge water. When the water flow is turned off, the water baffle is reset to achieve the automatic water-stopping function.

[0004] However, due to the weight of the water stop, it must be lifted up. Before the showerhead is turned on and the water actually flows out, the water needs to be held in the pressure chamber for a period of time to generate sufficient buoyancy. This results in high starting water pressure and delayed water flow. Therefore, a more novel and ingenious water stop design is urgently needed. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide a water outlet structure and a shower device thereof that can be turned on and off immediately, so as to solve the above-mentioned problem.

[0006] The present invention adopts the following scheme:

[0007] The present application provides a water outlet structure that can be turned on and off immediately, including a water inlet, a water channel, and a water outlet; the water channel is provided with a switch assembly, and the switch assembly is controlled by water pressure. When water flows through the water inlet, the switch assembly opens to connect the water inlet and the water outlet, and closes to close the water inlet and the water outlet when water is cut off; the water outlet structure also includes an internal chamber, which is connected to the water outlet; after the switch assembly is closed, the chamber is relatively closed and negative pressure is formed; the switch assembly includes at least one guide member; the guide member has the function of moving downward to a first position under the action of water pressure to open the water inlet state of the switch assembly, and returning to a state of opening the water inlet state after the pressure is released. The water-cut state of the switch assembly is closed by the reset button, and the water-cut state is closed by the reset button. The water-cut state is closed by the reset button, and the water-cut state is closed by the reset button. The water-cut state is closed by the reset button, and the water-cut state is closed by the reset button. The delay component is configured to move synchronously with the guide component to the first position, and when the guide component is reset to the second position or the third position, the delay component is relatively delayed in resetting after the internal chamber is relatively closed, and further extracts the air in the chamber to form another superimposed negative pressure.

[0008] As a further improvement, the guide member includes: a seat body, a movable rod and an elastic member; the seat body is controlled by water pressure and can move relative to the guide in the up and down directions of water inlet; the movable rod is linked to the seat body; the elastic member abuts against the bottom of the seat body, and keeps the seat body and the movable rod in the third position when no water is entering; wherein, a limit member for quickly limiting the seat body to move down to the first position is provided on one side of the water outlet end, and the elastic member abuts between the limit member and the seat body; a guide cylinder that is plugged and adapted to the movable rod is provided on one side of the water inlet end, and after moving to the second position, the movable rod contacts 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 inserted and placed in the guide cylinder.

[0009] As a further improvement, the delay component includes a piston member movably engaged with the seat body, and a reset member abutting against the bottom of the piston member; there is a travel margin between the piston member and the seat body so that the two can form an upward movement one after the other.

[0010] As a further improvement, the reset member and the elastic member share the same limit member, and the elastic force of the reset member is smaller than the elastic force of the elastic member. After the pressure is released, the elastic member drives the seat to quickly rebound to the second position and the third position.

[0011] 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.

[0012] As a further improvement, after the piston member rebounds, it can at least extract the air in the chamber.

[0013] As a further improvement, the opposite sides of the seat body are respectively provided with bayonet sockets adapted for their respective piston members, and the main body of the piston member is correspondingly provided with a lower flange and an upper flange. When it moves downward under the action of water pressure, the bayonet socket abuts against the lower flange so that the two move synchronously. After the pressure is released, since the seat body resets faster than the piston member, the bayonet socket moves relative to the upper flange so that the relative margin between the two is reduced.

[0014] As a further improvement, after the seat body moves to the third position, the reset member drives the piston member to move to the reset state with a delay, and at this time the lower flange is clamped on the bayonet.

[0015] As a further improvement, the sealing component includes a silicone sheet; the silicone sheet has an eight-shaped cross-section and is supported around the water outlet at the water outlet end. After water is passed, the water flow presses the silicone sheet downward to avoid the water outlet passage. After the water is cut off, the silicone sheet elastically returns to its initial state to seal the water outlet, and after moving to the second position on the guide component, the two cooperate with each other to make the internal chamber relatively sealed.

[0016] The present application further provides a shower, comprising a shower body and a water outlet structure configured on the shower body that can be turned on and off immediately; wherein, a water inlet joint forming the water inlet end and a water outlet panel forming the water outlet end are provided in the top spray shower body, and the water channel and the internal chamber are correspondingly formed in the shower body.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0018] When the water inlet is closed, the switch assembly is quickly closed, so that the internal chamber is relatively sealed and negative pressure is formed, and the water outlet connected to the internal chamber can be closed and stopped immediately without causing residual water to drip at the water outlet. In particular, the guide member of the switch assembly can switch between a first position, a second position and a third position, and correspondingly moves downward to the first position after being acted upon by water pressure, opens the water flow channel to connect the water inlet and the water outlet, and resets and moves upward to the second position after the pressure is released, correspondingly blocking the water inlet and the water outlet and keeping the internal chamber relatively closed. After continuing to reset and move upward to the third position, the air in the chamber is extracted by the guide member to form negative pressure, and then the water outlet is quickly stopped in the exhaust state.

[0019] 2. Through the cooperation between the guide member and the delay member, when the guide member is reset to the second position or the third position, the delay member continues to remain in the original position for a period of time. This delayed action will further enhance the negative pressure in the chamber, forming a superimposed negative pressure. The superimposed negative pressure effect can more effectively prevent the water flow from being retained at the water outlet or even dripping after it stops, thereby further reducing water dripping and water resource waste. In particular, after the water flow is turned off, the residual water will be affected by the negative pressure to prevent water droplets from accumulating. The delay member can remain in place when the guide member is reset, delaying its own reset process, ensuring that after the water flow is turned off, the guide member's air pumping state is executed, and through another air pumping operation of the delay member that is not too hasty, the negative pressure can be maintained for a certain period of time again, further enhancing the water-stopping effect.

[0020] 3. By configuring a sealing component at the water outlet, it automatically contracts when water is flowing, and automatically returns to its original position after the water is cut off, thereby expanding and blocking the water outlet. In conjunction with the guide component resetting to the second position, the upper and lower closure of the chamber is achieved, effectively improving the water-stopping effect and sealing performance. The adaptive switching state of the sealing component can quickly respond to water flow and water cut-off, which not only ensures the accuracy of water flow control, but also avoids residual water dripping and water retention.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0031] Example

[0032] Combine Figures 1 to 6 This embodiment provides a water outlet structure that can be turned on and off, including a water inlet end 1, a water channel (such as Figure 1 The water channel is provided with a switch assembly 3. The switch assembly 3 is controlled by water pressure and opens when water flows through the water inlet 1 to connect the water inlet 1 and the water outlet 2, and closes when water flows through the water inlet 1 to close the water inlet 1 and the water outlet 2.

[0033] The water outlet structure further comprises an internal chamber, which is communicated with the water outlet end 2. When the switch assembly 3 is closed, the chamber is relatively sealed and forms a negative pressure.

[0034] The switch assembly 3 includes at least one guide member 31. The guide member 31 is capable of being moved downward to a first position under water pressure to open the switch assembly 3 for water inlet, reset to a second position after pressure is released to close the switch assembly 3 for water cutoff, and reset to a third position to extract air from the chamber to create a negative pressure in the air extraction state.

[0035] The above-mentioned water outlet structure that turns on and off immediately, when water flows through the water inlet end 1, the switch component 3 will quickly open, so that the water inlet end 1 and the water outlet end 2 are connected and water is supplied for use. When the water is cut off from the water inlet end 1, the switch component 3 will quickly close, so that the internal chamber is relatively closed and negative pressure is formed, and the water outlet end 2 connected to the internal chamber can be turned on and off immediately without causing residual water at the water outlet end 2 to leak. In particular, the guide member 31 of the switch component 3 can switch between the first position, the second position and the third position, and correspondingly move downward to the first position after being acted upon by water pressure, open the water flow channel to connect the water inlet end 1 and the water outlet end 2, and reset and move upward to the second position after the pressure is released, correspondingly blocking the water inlet end 1 and the water outlet end 2 and keeping the internal chamber relatively closed. After continuing to reset and move upward to the third position, the air in the chamber is extracted by the guide member 31 to form negative pressure, and then in the exhaust state, rapid water stopping is achieved at the water outlet end 2.

[0036] To this end, the guide member 31 of the switch assembly 3 achieves a rapid water-stopping function, preventing water dripping from showerheads and other shower equipment after the water flow is turned off. This not only saves water but also significantly improves the user experience by reducing water stains and residual water droplets. Furthermore, the three-stage switching of the guide member 31, which moves up and down, not only improves the efficiency of the switch, but also ensures the accuracy and reliability of each operation stage, providing users with a more environmentally friendly, water-saving, and comfortable user experience.

[0037] As shown in the figure, in this embodiment, the guide member 31 includes a base 311, a movable rod 312, and an elastic member 313. The base 311 is controlled by water pressure to move relative to the guide in the vertical direction of water inflow. The movable rod 312 cooperates with the base 311, and the elastic member 313 abuts against the bottom of the base 311, maintaining the base 311 and the movable rod 312 in the third position when no water is flowing.

[0038] A stopper 21 (which may be referred to as a water outlet cover below) is provided on one side of the water outlet end 2 for quickly limiting the downward movement of the seat body 311 to the first position. The elastic member 313 abuts between the stopper 21 and the seat body 311. A guide cylinder 11 is provided on one side of the water inlet end 1 to be plugged into and adapted to the movable rod 312. After moving to the second position, the movable rod 312 contacts the guide cylinder 11 to block the water flow along the guide cylinder 11 into the water inlet end 1. After moving to the third position, the movable rod 312 is plugged into the guide cylinder 11.

[0039] In the above description, the relative vertical movement of the seat 311 is controlled by water pressure, allowing precise control of its movement and enabling multi-stage operation, from turning on the water, to shutting off the water, and then to negative pressure water stopping. The elastic member 313 abuts against the bottom of the seat 311 to maintain the seat 311 and the movable rod 312 in the third position until the water flow is activated. In the absence of water pressure, the seat 311 remains in its default initial position, ensuring reliable activation of the structure and preventing accidental activation in the absence of water flow.

[0040] In addition, a limiter 21 is provided on one side of the water outlet 2 to quickly limit the seat 311 from moving down to the first position, ensuring that the seat 311 does not move excessively due to water pressure fluctuations or other factors, which helps to accurately control its switching operation. On the other hand, a guide cylinder 11 adapted to the movable rod 312 is provided on the side of the water inlet 1 to ensure the accurate movement of the movable rod 312. The guide cylinder 11 ensures the effective blocking or opening of the water flow in the waterway through the in-and-out movement of the movable rod 312. When moved to the third position, the movable rod 312 is fully inserted into the guide cylinder 11, and a piston-like plug-in fit is formed between the movable rod 312 and the guide cylinder 11, ensuring that the air in the chamber is further extracted.

[0041] like Figures 2 to 6 As shown, in this embodiment, the switch assembly 3 also includes a delay member 32. The delay member 32 can move synchronously with the base 311 to the first position, and when the guide member 31 is reset to the second position or the third position, the delay member 32 is configured to delay reset and further extract the air in the chamber to form another superimposed negative pressure. Thus, through the mutual cooperation between the guide member 31 and the delay member 32, when the guide member 31 is reset to the second position or the third position, the delay member 32 continues to remain in the original position for a period of time. Such a delayed action will further enhance the negative pressure in the chamber, forming a superimposed negative pressure. The superimposed negative pressure effect can more effectively prevent the water flow from being retained at the water outlet 2 or even dripping after it stops, thereby further reducing water dripping and water resource waste. In particular, after the water flow is turned off, the residual water will be affected by the negative pressure to prevent water droplets from accumulating. The delay component 32 can remain in place when the guide component 31 is reset, delaying its own reset process, ensuring that after the water flow is closed, the vacuum state of the guide component 31 is executed, and then another vacuum operation of the delay component 32 is performed again without being too hasty, which can maintain the negative pressure for a certain period of time again, further enhancing the water-stopping effect.

[0042] Specifically, the delay member 32 includes a piston member 321 that is movably engaged with the base 311, and a reset member 322 that abuts against the bottom of the piston member 321. There is a travel margin between the piston member 321 and the base 311, so that the two can form an upward tandem movement. Therefore, when the water flow is turned off, the movement of the piston member 321 will lag behind the movement of the base 311, ensuring that the base 311 and the piston member 321 do not reset at the same time. This tandem movement allows the piston member 321 to apply additional air extraction at the appropriate time, further enhancing the negative pressure effect in the chamber. It should be mentioned that the stroke allowance allows the reset actions of the seat body 311 and the piston member 321 to be not completely synchronized, thereby making the delayed reset effect more obvious. The successive movements brought about by the stroke allowance can enable the piston member 321 to continue to apply pressure during the idle period after the water flow is disconnected, thereby increasing the negative pressure in the chamber and effectively providing negative pressure to the water outlet end 2, making the negative pressure superposition effect more continuous, and the water-stopping effect is also improved, ensuring that the phenomenon of water dripping is completely suppressed.

[0043] It should be noted that the piston member 321 can be realized by a breathing valve (not shown) that is adaptive to exhaust use. After the reset member 322 drives the piston member 321 to reset and move, the gas in the chamber is discharged through the breathing valve, and when it moves downward under pressure, the breathing valve is used to connect air to the chamber, thereby realizing the reciprocating in and out exhaust of the piston. In addition, the movable rod 312 of the guide member 31 is inserted into the guide cylinder 11, and the air in the chamber is initially extracted to form a negative pressure. At this time, it can at least ensure that the accumulated water at the water outlet end 2 is maintained without dripping. The lagging piston member 321 extracts the air in the chamber for a second time to form a superimposed negative pressure, which can keep the accumulated water in the water outlet end 2 more tightly, and even flow back along the water channel away from the water outlet end 2.

[0044] The reset member 322 and the elastic member 313 share the same limiter 21, and the elastic force of the reset member 322 is less than that of the elastic member 313. After the pressure is released, the elastic member 313 drives the seat 311 to quickly rebound to the second and third positions. Preferably, after the seat 311 rebounds to the second position, the movable rod 312 and the guide cylinder 11 are sealed, so that the chamber is sealed at least at the top (the bottom is correspondingly sealed by the sealing member 33 described below). After the seat 311 switches to the second position, the reset member 322 drives the piston member 321 to return to its original position, thereby extracting air.

[0045] After the seat 311 rebounds to the second or third position, the reset member 322 drives the piston 321 to rebound to its reset state. Apparently, after the piston 321 rebounds, it can at least extract air from the chamber. It is understood that the piston 321 is movably inserted into the internal chamber and connected to the exterior through a piston-like plug-in connection. After the reset movement, the piston 321 correspondingly extracts air from the chamber to the exterior.

[0046] Furthermore, the seat body 311 is provided with respective retaining clips 314 on opposite sides thereof, adapted for use with the respective piston members 321. The piston member 321 is provided with corresponding lower and upper flanges 323 and 324 on its main body. When the seat body 311 moves downward under the action of water pressure, the retaining clips 314 abut against the lower flange 323, enabling the two to move synchronously. After the pressure is released, the seat body 311 returns to its original position faster than the piston member 321, causing the retaining clips 314 to move toward the upper flange 324, reducing the relative clearance between the two. Furthermore, after the seat body 311 moves to the third position, the return member 322 delays the movement of the piston member 321 to its original position, at which point the lower flange 323 is engaged with the retaining clips 314.

[0047] When the water is turned on, the water pressure pushes the seat 311 downward, and the bayonet 314 engages and cooperates with the lower flange 323 to drive the piston 321 to move together, ensuring accurate synchronous movement. When the water is turned off, the corresponding pressure is released, causing the seat 311 and bayonet 314 to move relative to each other toward the upper flange 324 until they reach the second or third position. At this time, the reset member 322 drives the piston 321 to return until the lower flange 323 abuts the bayonet 314, mutually limiting and cooperating, and preparing for the next stage of synchronous movement.

[0048] like Figure 2 、 Figure 7 and Figure 8 As shown, in this embodiment, a sealing member 33 is further provided at the water outlet end 2 to cooperate with the water outlet. The sealing member 33 is configured to swing to a contracted state under the action of water flow to avoid water outlet when water is flowing, and to reset to an expanded state to block water outlet and cooperate with the guide member 31 to seal the internal chamber when water is cut off. Therefore, by configuring the sealing member 33 at the water outlet end 2, it automatically contracts when water is flowing, and automatically elastically resets after water is cut off to expand and block water outlet, thereby cooperating with the guide member 31 to reset to the second position to achieve the upper and lower sealing of the chamber, effectively improving the water-stopping effect and sealing performance, and the adaptive switching state of the sealing member 33 can quickly respond to water flow and water cut-off, not only ensuring the accuracy of water flow control, but also avoiding residual water dripping and water retention.

[0049] Furthermore, the sealing member 33 includes a silicone sheet 331. The silicone sheet 331 has an eight-shaped cross-section and is supported around the water outlet of the water outlet end 2. When water is flowing, the water presses the silicone sheet 331 downward to avoid the water flow passage. When the water is cut off, the silicone sheet 331 elastically returns to its initial state, thereby sealing the water outlet. After moving to the second position on the guide member 31, the silicone sheet 331 and the guide member 31 cooperate to relatively seal the internal chamber, thereby facilitating the subsequent extraction of air by the guide member 31 and the delay member 32.

[0050] Combine Figure 7 and Figure 8 This embodiment further provides a shower, comprising a shower body 4 and an on-off water outlet structure disposed on the shower body 4. The shower body 4 is provided with a water inlet connector 5 forming the water inlet end 1 and a water outlet panel 6 forming the water outlet end 2, and the water channel and internal chamber are correspondingly formed within the shower body 4.

[0051] It is understandable that the shower head body 4 is specifically a top spray shower head (such as Figure 1 As shown), hand shower parts (as shown Figure 7 As shown), etc., for users to use for showering.

[0052] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
