Description

Technical Field

[0001] The invention relates to a control valve which is easy to use and a water outlet device having the control valve. Background Art

[0002] In buildings with a centralized water supply system, each water outlet (such as faucets and showers) is supplied by the central water supply. When hot water is needed, the cold water remaining in the pipe between the central water supply system and the outlet must be drained. This process, which often takes a long time for the outlet to drain the cold water and flow into hot water, requires users to constantly touch the draining water to check whether it has reached the desired temperature. This is inconvenient and does not guarantee that the water temperature has reached the desired level. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides an easy-to-use control valve and a water outlet device having the control valve, which can judge whether the water temperature reaches the predetermined value by observing the different water outlet states. Then, the user can use the water outlet terminal after confirming that the water temperature has reached the predetermined value. It is very convenient to use and has a very simple and reliable structure.

[0004] To achieve the above-mentioned purpose, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0005] A convenient control valve comprising:

[0006] A main body having a water inlet, a water outlet, a first water outlet channel, a second water outlet channel, and a third water outlet channel, wherein the first water outlet channel, the second water outlet channel, and the third water outlet channel are respectively connected to the water inlet and the water outlet;

[0007] a switching valve, for controlling the water inlet to switchably connect to the first water outlet channel or the second water outlet channel, the switching valve having an initial position and a use position, wherein when the switching valve is in the initial position, the water inlet is connected to the first water outlet channel, and when the switching valve is in the use position, the water inlet is connected to the second water outlet channel;

[0008] A temperature-sensing valve is provided in the first water outlet channel. When the temperature-sensing valve senses that the water temperature reaches a predetermined value, the temperature-sensing valve controls the first water outlet channel to close, thereby allowing the water at the water inlet to flow only from the third water outlet channel to the water outlet. The water outlet state of the water outlet is different before and after the temperature-sensing valve is closed.

[0009] In some preferred embodiments, the different water outlet states are manifested in different water outlet flow rates, different water outlet positions, different water outlet angles, or different water outlet splashes.

[0010] In some preferred embodiments, there is one water outlet, and the first water outlet channel, the second water outlet channel and the third water outlet channel are all connected to the water outlet, and the flow cross-sectional area of ​​the third water outlet channel is smaller than the flow cross-sectional area of ​​the first water outlet channel.

[0011] In some preferred embodiments, there are two water outlets, namely a first water outlet and a second water outlet, the first water outlet channel connects the water inlet and the first water outlet, the second water outlet channel connects the water inlet and the second water outlet, and the third water outlet channel connects the water inlet and the second water outlet.

[0012] In some preferred embodiments, there are three water outlets, namely the first water outlet, the second water outlet and the third water outlet. The first water outlet channel connects the water inlet and the first water outlet, the second water outlet channel connects the water inlet and the second water outlet, and the third water outlet channel connects the water inlet and the third water outlet.

[0013] In some preferred embodiments, a check valve is further provided on the first water outlet channel.

[0014] In some preferred embodiments, a temperature-sensitive valve port is formed on the first water outlet channel, and the temperature-sensitive valve includes a matching plug and a memory spring. The memory spring is in a contracted state when the water temperature has not reached a predetermined value, thereby driving the plug away from the temperature-sensitive valve port. The memory spring is in an extended state when the water temperature reaches a predetermined value, thereby driving the plug to seal the temperature-sensitive valve port.

[0015] In some preferred embodiments, when the switching valve is in the initial position, the water inlet is connected to the first water outlet channel and the third water outlet channel at the same time; when the switching valve is in the use position, the water inlet is connected to the second water outlet channel and the third water outlet channel at the same time.

[0016] In some preferred embodiments, a first switching valve port and a second switching valve port are formed in the body, and the switching valve includes a switching valve core and a return spring. When the switching valve is in the initial position, the switching valve core is in a position of opening the first switching valve port and closing the second switching valve port under the action of the return spring, and the water inlet is connected to the first water outlet channel and the third water outlet channel at the same time through the first switching valve port; when the switching valve is driven to the use position, the switching valve core is in a position of opening the second switching valve port and closing the first switching valve port, and the water inlet is connected to the second water outlet channel and the third water outlet channel at the same time through the second switching valve port.

[0017] In some preferred embodiments, the water outlet is provided with a threaded portion, and the control valve is connected to a water outlet terminal via the threaded portion.

[0018] According to another aspect of the present invention, the present invention provides the following technical solutions:

[0019] A water outlet device comprises a water outlet terminal and any one of the control valves described above, wherein the water outlet terminal is connected to the water outlet of the control valve.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention provides three water outlet channels, a switching valve and a temperature-sensing valve in the main body. When the switching valve is in the initial position, the water inlet is connected to the first water outlet channel. When the switching valve is in the use position, the water inlet is connected to the second water outlet channel. The temperature-sensing valve is provided in the first water outlet channel. When the temperature-sensing valve senses that the water temperature has reached a predetermined value, the temperature-sensing valve controls the first water outlet channel to close, thereby allowing the water at the water inlet to flow only from the third water outlet channel to the water outlet. The water outlet state is different before and after the temperature-sensing valve is closed, so that whether the water temperature has reached the predetermined value can be judged by observing the difference in the water outlet state. The user can use the water outlet terminal only after confirming that the water temperature has reached the predetermined value. The use is very convenient and the structure is very simple and reliable.

[0022] 2. By designing the flow cross-sectional area of ​​the third water outlet channel to be smaller than the flow cross-sectional area of ​​the first water outlet channel, it is possible to judge whether the water temperature has reached the predetermined value by observing the difference in water outlet flow rates. The structure is simple. For example, when water is outlet from the first water outlet channel, the water outlet flow rate is large, and the water outlet state is manifested as a continuous water flow. When only the third water outlet channel is outlet, the water outlet flow rate is very small, and the water outlet state is manifested as intermittent dripping, so that the judgment can be made very intuitively.

[0023] 3. By designing the first water outlet channel and the third water outlet channel to flow out from different water outlets, it is possible to judge whether the water temperature reaches the predetermined value by observing the difference in the water outlet positions, and the structure is simple.

[0024] 4. The temperature sensing valve includes a matching plug and memory spring with simple structure and reliable function.

[0025] 5. The control valve of the present invention can itself serve as a water outlet terminal (such as a shower, faucet, spray gun, etc.), and the water at the water outlet of the control valve flows directly outward for use by the user; alternatively, the control valve of the present invention can also be connected to a water outlet terminal, and the water at the water outlet of the control valve flows into the water outlet terminal and then flows outward through the water outlet terminal.

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Please refer to Figures 1 to 5A control valve that is easy to use according to an embodiment of the present invention includes a body 10, a switching valve 20, and a temperature-sensing valve 30. The body 10 has a water inlet 11, a water outlet 12, a first water outlet channel 13, a second water outlet channel 14, and a third water outlet channel 15. The first water outlet channel 13, the second water outlet channel 14, and the third water outlet channel 15 are respectively connected to the water inlet 11 and the water outlet 12; the switching valve 20 is used to control the water inlet 11 to switch between being connected to the first water outlet channel 13 or the second water outlet channel 14. The switching valve 20 has an initial position and a use position. When the switching valve 20 is in the initial position, the water inlet 11 is connected to the first water outlet channel 13. When the switching valve 20 is in the use position, the water inlet 11 is connected to the first water outlet channel 13. The water inlet 11 is connected to the second water outlet channel 14; the temperature sensing valve 30 is provided in the first water outlet channel 13. When the temperature sensing valve 30 senses that the water temperature has reached a predetermined value, the temperature sensing valve 30 controls the first water outlet channel 13 to close, thereby allowing the water from the water inlet 11 to flow only from the third water outlet channel 15 to the water outlet 12. The water outlet 12 has different water outlet states before and after the temperature sensing valve 30 is closed, so that it is possible to judge whether the water temperature has reached the predetermined value by observing the difference in water outlet states. The user can use the water outlet terminal only after confirming that the water temperature has reached the predetermined value. The use is very convenient and the structure is very simple and reliable. Among them, the different water outlet states can be manifested in different water outlet flow rates, different water outlet positions, different water outlet angles, or different water outlet splashes, etc., as long as the differences can be intuitively discovered through observation.

[0040] In this embodiment, a single water outlet 12 is provided, and a first water outlet channel 13, a second water outlet channel 14, and a third water outlet channel 15 are all connected to the water outlet 12. The flow cross-sectional area of ​​the third water outlet channel 15 is smaller than that of the first water outlet channel 13. By designing the flow cross-sectional area of ​​the third water outlet channel 15 to be smaller than that of the first water outlet channel 13, it is possible to determine whether the water temperature has reached a predetermined value by observing the difference in the water flow rate. This simple structure allows for, for example, when water is flowing from the first water outlet channel 13, the water flow rate is large, and the water flow is manifested as a continuous flow. When only the third water outlet channel 15 is flowing, the water flow rate is very small, and the water flow is manifested as intermittent dripping, making it very intuitive to determine whether the water temperature has reached a predetermined value.

[0041] In this embodiment, a check valve 40 is further provided on the first water outlet channel 13 to prevent water from flowing back into the water inlet 11 .

[0042] In this embodiment, a temperature-sensitive valve port 131 is formed on the first water outlet channel 13. The temperature-sensitive valve 30 includes a matching plug 31 and a memory spring 32. When the water temperature does not reach a predetermined value, the memory spring 32 is in a contracted state, thereby driving the plug 31 away from the temperature-sensitive valve port 131. When the water temperature reaches a predetermined value, the memory spring 32 is in an extended state, thereby driving the plug 31 to block the temperature-sensitive valve port 131. Specifically, in this embodiment, two memory springs 32 are provided, respectively abutting between the two sides of the plug 31 and the body 10. Of course, only one memory spring 32 may be provided. The memory spring 32 can be made of an existing temperature-sensitive memory metal.

[0043] In this embodiment, when the switching valve 20 is in the initial position, the water inlet 11 is connected to the first water outlet channel 13 and the third water outlet channel 15 at the same time; when the switching valve 20 is in the use position, the water inlet 11 is connected to the second water outlet channel 14 and the third water outlet channel 15 at the same time.

[0044] In this embodiment, a first switching valve port 16 and a second switching valve port 17 are formed in the body 10. The switching valve 20 includes a switching valve core 21 and a return spring 22. When the switching valve 20 is in the initial position, the switching valve core 21 is in a position to open the first switching valve port 16 and close the second switching valve port 17 under the action of the return spring 22. The water inlet 11 is connected to the first water outlet channel 13 and the third water outlet channel 15 through the first switching valve port 16. When the switching valve 20 is driven to the use position, the switching valve core 21 is in a position to open the second switching valve port 17 and close the first switching valve port 16. The water inlet 11 is connected to the second water outlet channel 14 and the third water outlet channel 15 through the second switching valve port 17.

[0045] In this embodiment, the water outlet 12 is provided with a threaded portion, and the control valve can be connected to a water outlet terminal through the threaded portion.

[0046] In this embodiment, a button 50 is movably provided on the body 10 , and the button 50 is linked to the switching valve core 20 to drive the switching valve core 20 to move from the initial position to the use position.

[0047] See also Figure 3 At this time, the switching valve 20 is in the initial position, the water inlet 11 is connected to the first water outlet channel 13 and the third water outlet channel 15 at the same time, and the water temperature entering the water inlet 11 is lower than the predetermined value, so that the temperature sensing valve 30 is in the position of opening the temperature sensing valve port 131. In this way, the water flow from the water inlet 11 can flow from the first water outlet channel 13 and the third water outlet channel 15 to the water outlet 12. Since the flow cross-sectional area of ​​the third water outlet channel 15 is much smaller than the flow cross-sectional area of ​​the first water outlet channel 13, most of the water will flow to the water outlet 12 through the third water outlet channel 15. Figure 3The dotted line with an arrow in the middle represents the path of water flowing out through the third water outlet channel 15, and the water outlet state is manifested as a continuous water flow.

[0048] See also Figure 4 When the temperature of the water entering the water inlet 11 reaches a predetermined value, the memory spring 32 is in an extended state, thereby driving the plug 31 to block the temperature sensing valve port 131. At this time, the water inlet 11 is only connected to the third water outlet channel 15. The water flow rate of the third water outlet channel 15 is much smaller than that of the first water outlet channel 13. The water outlet state is manifested as intermittent dripping, so that it can be very intuitive to judge that the water temperature has reached the predetermined value.

[0049] See also Figure 5 When the water temperature reaches the predetermined value, the user can press the button 50, which in turn links the switching valve core 20 to drive the switching valve core 20 to move from the initial position to the use position. When the switching valve 20 is in the use position, the water inlet 11 is connected to the second water outlet channel 14, so that water can flow out from the water outlet 12 for normal use.

[0050] A water outlet device includes a water outlet terminal and any of the above control valves, the water outlet terminal is connected to the water outlet 12 of the control valve, water from the water outlet 12 of the control valve flows into the water outlet terminal, and then flows out through the water outlet terminal.

[0051] It is understandable that the control valve of the present invention can also serve as a water outlet terminal (such as a shower, faucet, spray gun, etc.), and the water at the water outlet 12 of the control valve flows directly outward for use by the user. When the control valve directly serves as a water outlet terminal, the number of water outlets 12 can also be set to multiple, such as 2 or 3 or more. In some embodiments, the number of water outlets 12 can be set to 2, namely a first water outlet 12 and a second water outlet 12, a first water outlet channel 13 connects the water inlet 11 and the first water outlet 12, a second water outlet channel 14 connects the water inlet 11 and the second water outlet 12, and a third water outlet channel 15 connects the water inlet 11 and the second water outlet 12. By designing the flow cross-sectional area of ​​the third water outlet channel 15 to be smaller than the flow cross-sectional area of ​​the first water outlet channel 1313, it is possible to judge whether the water temperature reaches the predetermined value by observing the difference in water outlet flow rates. The structure is simple. For example, when water is outlet from the first water outlet channel 13, the water outlet flow rate is large, and the water outlet state is manifested as a continuous water flow. When only water is outlet from the third water outlet channel 15, the water outlet flow rate is very small, and the water outlet state is manifested as intermittent dripping, so that the judgment can be made very intuitively.

[0052] In some other embodiments, the number of water outlets 12 can be set to 3, namely the first water outlet 12, the second water outlet 12 and the third water outlet 12, the first water outlet channel 13 connects the water inlet 11 and the first water outlet 12, the second water outlet channel 14 connects the water inlet 11 and the second water outlet 12, and the third water outlet channel 15 connects the water inlet 11 and the third water outlet 12.

[0053] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the inventive concept described herein by the teachings above or by techniques or knowledge in the relevant art.
