Abstract
Description
Technical Field
[0001] This invention relates to the technical field of water circuit switching valves, and particularly to a safety valve and a water outlet device. Background Technology
[0002] Most existing shower faucets use ordinary valve cores and lack automatic temperature control. Since users frequently adjust the temperature and flow rate, accidental operation can easily lead to a sudden increase in water temperature, resulting in scalding. There is also the possibility of a sudden interruption of cold water flow, leaving only hot water flowing out, which can also cause scalding. Summary of the Invention
[0003] The main objective of this invention is to provide a safety valve designed to reduce the possibility of burns to the human body.
[0004] To achieve the above objectives, the safety valve proposed in this invention comprises:
[0005] The housing, having an inlet, a first outlet, and a second outlet; and
[0006] The valve core assembly includes a valve core, a temperature sensing element, and a return spring. The temperature sensing element is disposed between one end of the valve core and the housing, and the return spring is disposed between the other end of the valve core and the housing. The temperature sensing element deforms under temperature changes to change the total effect of the temperature sensing element and the return spring on the valve core, switching the blocking position of the valve core so that the safety valve has a first water outlet state and a second water outlet state. In the first water outlet state, the valve core is blocked at the second water outlet, and the water flowing in from the inlet flows out through the first water outlet. In the second water outlet state, the valve core is blocked at the first water outlet, and the water flowing in from the inlet flows out through the second water outlet.
[0007] Optionally, the temperature sensing element is a temperature sensing spring. In the first water discharge state, the elastic force of the temperature sensing spring is less than the elastic force of the reset spring; in the second water discharge state, the elastic force of the temperature sensing spring is greater than the elastic force of the reset spring.
[0008] Optionally, the safety valve further includes an adjustment component installed on the housing. The safety valve also has a third water outlet state. In the third water outlet state, the adjustment component drives the valve core to block the second water outlet, and the water flowing in from the inlet flows out sequentially through the first water outlet channel and the first water outlet.
[0009] Optionally, the housing is provided with mounting holes, the valve core is provided with an adjusting plate, and the adjusting assembly includes a rotating shaft. The outer peripheral surface of the rotating shaft near one end of the valve core is provided with an adjusting protrusion. In the first water outlet state or the second water outlet state, the adjusting plate and the adjusting protrusion are spaced apart. In the third water outlet state, the rotating shaft is rotated so that the adjusting protrusion lifts the adjusting plate, thereby causing the valve core to block the second water outlet. The water flowing in from the inlet flows out sequentially through the first water outlet channel and the first water outlet.
[0010] Optionally, the adjusting protrusion is a cam structure.
[0011] Optionally, the adjustment assembly further includes a handle, which is fixedly mounted on the rotating shaft, and the handle is provided with anti-slip markings.
[0012] Optionally, the rotating shaft is provided with a limiting protrusion, and the housing is provided with a limiting groove. The limiting groove is arc-shaped and extends circumferentially along the rotating shaft.
[0013] Optionally, the adjusting assembly further includes a retaining ring and a sealing joint. The sealing joint is installed at the mounting hole. The end of the rotating shaft away from the housing is provided with an annular abutment protrusion. The rotating shaft is inserted into the sealing joint from the inside out. The retaining ring is clamped on the rotating shaft and located between the abutment protrusion and the sealing joint.
[0014] Optionally, the valve core is a piston, and a first water outlet channel is formed inside the piston. In the first water outlet state, the return spring pushes one end of the piston to block the second water outlet. The water flowing in from the inlet flows out through the first water outlet channel and the first water outlet in sequence. In the second water outlet state, the other end of the piston is blocked at the first water outlet, so that the valve core is blocked at the first water outlet.
[0015] Optionally, the safety valve further includes a filter plate with multiple water passage holes. The valve core and the inner wall of the housing form a second water outlet channel. The filter plate is installed in the second water outlet channel, and both the water passage holes and the second water outlet channel are connected to the second water outlet.
[0016] Optionally, the safety valve further includes an inlet connector for connecting to the inlet pipe and an outlet connector for connecting to the outlet pipe. The inlet connector is sealed to the inlet and is connected to both the inlet and the first outlet channel. The outlet connector is sealed to the first outlet and is connected to the first outlet.
[0017] The present invention also proposes a water outlet device, including the safety valve described above.
[0018] The safety valve of this invention includes a housing and a valve core assembly. The housing has an inlet, a first outlet, and a second outlet. The valve core assembly includes a valve core, a temperature sensing element, and a return spring. The temperature sensing element is located between one end of the valve core and the housing, and the return spring is located between the other end of the valve core and the housing. The temperature sensing element deforms in response to temperature changes, altering the overall effect of the temperature sensing element and the return spring on the valve core, thereby switching the sealing position of the valve core. This allows the safety valve to have a first outlet state and a second outlet state. When the safety valve is in the first outlet state, the temperature of the water flowing into the inlet is lower than the preset temperature of the temperature sensing element. The return spring pushes the valve core to seal the second outlet. Water flowing in from the inlet flows out through the first outlet. When the water temperature of the water flowing in from the inlet suddenly rises or gradually rises, the safety valve is in the second outlet state. At this time, the temperature sensing element deforms due to heat, thereby pushing the valve core to seal the first outlet, and then the water flowing in from the inlet flows out through the second outlet. The water flowing out of the first outlet is for the user's use. The second outlet is deviated from the user's setting, so that water with a temperature higher than the preset temperature of the temperature sensing element will flow out from the second outlet, thereby reducing the possibility of the user being scalded and improving the user experience.

[0038] Reference Figure 1 , Figure 2 and Figure 7 This invention proposes a safety valve, comprising:
[0039] The housing 10 is provided with an inlet 101, a first outlet 102, and a second outlet 103; and
[0040] The valve core 21 assembly includes a valve core 21, a temperature sensing element, and a return spring 23. The temperature sensing element is disposed between one end of the valve core 21 and the housing 10, and the return spring 23 is disposed between the other end of the valve core 21 and the housing 10. The temperature sensing element deforms under temperature changes to change the overall effect of the temperature sensing element and the return spring 23 on the valve core 21, switching the blocking position of the valve core 21 so that the safety valve has a first water outlet state and a second water outlet state. In the first water outlet state, the valve core 21 is pushed to block the second water outlet 103, and the water flowing in from the inlet 101 flows out through the first water outlet 102. In the second water outlet state, the valve core 21 is blocked at the first water outlet 102, so that the valve core 21 is blocked at the first water outlet 102.
[0041] The safety valve of this invention includes a housing 10 and a valve core 21 assembly. The housing 10 is provided with an inlet 101, a first outlet 102, and a second outlet 103. The valve core 21 assembly includes a valve core 21, a temperature sensing element, and a return spring 23. The temperature sensing element is located between one end of the valve core 21 and the housing 10, and the return spring 23 is located between the other end of the valve core 21 and the housing 10. The temperature sensing element deforms due to temperature changes, thereby changing the overall action of the temperature sensing element and the return spring 23 on the valve core 21, and thus switching the blocking position of the valve core 21. This allows the safety valve to have a first outlet state and a second outlet state. When the safety valve is in the first outlet state, the temperature of the water flowing into the inlet 101 is lower than the preset temperature of the temperature sensing element. Temperature, return spring 23 pushes valve core 21 to block the second outlet 103, water flowing in from inlet 101 flows out through first outlet 102. When the water temperature of the water flowing in from inlet 101 suddenly rises or gradually rises, the safety valve is in the second outlet state. At this time, the temperature sensing element is heated and deformed, thereby pushing valve core 21 to block the first outlet 102, so that the water flowing in from inlet 101 flows out through second outlet 103. The water flowing out of first outlet 102 is for user use. Second outlet 103 is deviated from the user setting, so that water with a temperature higher than the preset temperature of the temperature sensing element will flow out from second outlet 103, thereby reducing the possibility of user being scalded and improving the user experience.
[0042] It should be noted that the preset temperature can be 35℃, 40℃, etc., and can be set according to user needs and seasonal changes such as summer and winter.
[0043] In this embodiment, the temperature sensing element is a temperature sensing spring 22. In the first water outlet state, the elastic force of the temperature sensing spring 22 is less than the elastic force of the return spring 23; in the second water outlet state, the elastic force of the temperature sensing spring 22 is greater than the elastic force of the return spring 23. Thus, in the first water outlet state, the return spring 23 pushes the valve core 21 to compress the temperature sensing spring 22, thereby causing the valve core 21 to block the second water outlet 103, so that the water flowing in from the inlet 101 flows out from the first water outlet 102. When the safety valve is in the second water outlet state, the temperature sensing spring 22 pushes the valve core 21 to compress the return spring 23, thereby causing the valve core 21 to block the first water outlet 102, so that the water flowing in from the inlet 101 flows out from the second water outlet 103.
[0044] Reference Figure 6Understandably, when a user needs to use water at a higher temperature to wash vegetables, the second water outlet 103 is not convenient to store because it is off-center from the user's settings. Therefore, in another embodiment, the safety valve also includes an adjustment component installed on the housing 10. The safety valve also has a third water outlet state. In the third water outlet state, the adjustment component drives the valve core 21 to block the second water outlet 103, and the water flowing in from the inlet 101 flows out sequentially through the first water outlet channel 211 and the first water outlet 102. This allows the user to use water at temperatures exceeding the preset temperature of the temperature sensor when the user needs it. The adjustment component forces the valve core 21 to adjust its position. At this time, the combined force of the adjustment component and the return spring 23 is greater than the force of the temperature sensor, causing the valve core 21 to block the second outlet 103. Thus, even if the water temperature flowing into the inlet 101 is higher than the preset temperature, the user can still use the water. It should be noted that in the third water outlet state, water at temperatures higher or lower than the preset temperature of the temperature sensor can flow out through the first outlet 102.
[0045] Reference Figure 1 , Figure 2 , Figure 8 and Figure 10 Specifically, the housing 10 is provided with mounting holes, the valve core 21 is provided with an adjusting plate 212, and the adjusting assembly includes a rotating shaft 31. The outer peripheral surface of the rotating shaft 31 near one end of the valve core 21 is provided with an adjusting protrusion 311. In the first water outlet state or the second water outlet state, the adjusting plate 212 and the adjusting protrusion 311 are spaced apart. In the third water outlet state, the rotating shaft 31 is rotated so that the adjusting protrusion 311 lifts the adjusting plate 212, thereby driving the valve core 21 to block the second water outlet 103. The water flowing in from the inlet 101 flows out sequentially through the first water outlet channel 211 and the first water outlet 102.
[0046] Understandably, when the water temperature flowing into the inlet 101 is higher than the preset temperature of the temperature sensing element, but the user still needs to use it, the user can rotate the rotating shaft 31 and use the adjusting protrusion 311 on the rotating shaft 31 to forcibly move the valve core 21 toward the second outlet 103, ultimately sealing the valve core 21 at the second outlet 103, so that water with a temperature greater than or equal to the preset temperature of the temperature sensing element can still flow out from the first outlet 102.
[0047] Furthermore, the adjustment protrusion 311 is a cam structure, that is, the adjustment protrusion 311 is arc-shaped. Compared with the technical solution of directly setting the adjustment protrusion 311 to a square shape, setting it to an arc shape makes it easier and more convenient for users to rotate the rotating shaft 31.
[0048] In this embodiment, the adjustment component further includes a handle 33, which is fixedly installed on the rotating shaft 31. The handle 33 is provided with anti-slip marking protrusions 331. The anti-slip marking protrusions 331 serve two purposes: firstly, to facilitate the user's rotation of the handle 33, and secondly, to provide a prompt to the user. By judging the position of the anti-slip marking protrusions 331, the user can determine whether the adjustment component is in the on or off state.
[0049] Reference Figure 1 , Figure 2 and Figure 11 Furthermore, the rotating shaft 31 is provided with a limiting protrusion 312, and the housing 10 is provided with a limiting groove 105. The limiting groove 105 is arc-shaped and extends circumferentially along the rotating shaft 31. Understandably, through the limiting protrusion 312 and the limiting groove 105, the rotating shaft 31 can be rotated by a predetermined angle, thereby preventing the rotating shaft 31 from rotating excessively, which would cause the adjusting protrusion 311 to disengage from the adjusting plate 212, thereby preventing the safety valve from switching from the third water outlet state to the first water outlet state, thereby improving the stability and reliability of the safety valve, and thus improving the user experience.
[0050] Furthermore, during installation, if the installation proceeds from the outside in, the limiting protrusion 312 will interfere with the sealing joint 32, making installation impossible. Therefore, in one embodiment, the user first inserts the rotating shaft 31 into the housing 10 and then pushes the rotating shaft 31 outward, thereby allowing the rotating shaft 31 to be installed at the mounting hole. However, the cross-section of the rotating shaft 31 facing the valve core 21 should be spaced apart from the valve core 21. This ensures that the valve core 21 does not rub against the end face of the rotating shaft 31 when it moves up and down, thus facilitating the adjustment of the valve core 21 and improving the stability of the safety valve.
[0051] Reference Figure 8 and Figure 9 Therefore, in this embodiment, the adjustment assembly further includes a retaining ring 34 and a sealing joint 32. The sealing joint 32 is installed at the mounting hole. The end of the rotating shaft 31 away from the housing 10 is provided with an annular abutment protrusion 313. The rotating shaft 31 is inserted into the sealing joint 32 from the inside out. The retaining ring 34 is clamped on the rotating shaft 31 and located between the abutment protrusion 313 and the sealing joint 32. When the rotating shaft 31 is inserted into the sealing joint 32, the retaining ring 34 is clamped between the abutment protrusion 313 and the sealing joint 32. When disassembly is required, the retaining ring 34 is removed, and then the rotating shaft 31 is pushed inward, thereby facilitating the installation and disassembly of the rotating shaft 31.
[0052] Specifically, the valve core 21 is a piston, and a first water outlet channel 211 is formed inside the piston. In the first water outlet state, the return spring 23 pushes one end of the piston to block the second water outlet 103. The water flowing in from the inlet 101 flows out through the first water outlet channel 211 and the first water outlet 102 in sequence. In the second water outlet state, the other end of the piston is blocked at the first water outlet 102, so that the valve core 21 is blocked at the first water outlet 102.
[0053] Furthermore, the safety valve also includes an inlet connector for connecting to the inlet pipe and an outlet connector for connecting to the outlet pipe. The inlet connector is sealed to the inlet 101 and is connected to both the inlet 101 and the first outlet channel 211. The outlet connector is sealed to the first outlet 102 and is connected to the first outlet 102.
[0054] It should be noted that the connection between the inlet and outlet connectors and the housing 10 is a sealed connection. This is to ensure the sealing of the safety valve, so that the water can flow in the predetermined direction and thus ensure the normal operation of the safety valve.
[0055] Reference Figures 1 to 10 The specific operation process of the safety valve is as follows: When the safety valve is in the first water outlet state, the temperature of the water flowing into the inlet 101 is less than the preset temperature of the temperature sensing spring 22. At this time, the elastic force of the return spring 23 is greater than the elastic force of the temperature sensing spring 22. Under the action of the return spring 23, the piston moves towards the inlet 101, thereby sealing the upper end of the piston with the inlet 101, and causing the water flowing into the inlet 101 to flow out sequentially from the first water outlet channel 211 and the first water outlet 102. When the safety valve is in the second water outlet state, the temperature of the water flowing into the inlet 101 is greater than or equal to the preset temperature of the temperature sensing spring 22. 2. When heated, the temperature-sensing spring 22 pushes the piston downward, thereby blocking the first outlet 102. This allows the water flowing into the inlet 101 to flow out sequentially from the second outlet channel 104 and the second outlet 103. When the safety valve is in the third outlet state, regardless of whether the temperature of the water flowing into the inlet 101 is greater than the preset temperature of the temperature-sensing spring 22, the adjusting protrusion 311 forcibly lifts the adjusting plate 212 and the piston, thereby sealing the upper end of the piston with the inlet 101. This allows the water flowing into the inlet 101 to flow out sequentially from the first outlet channel 211 and the first outlet 102.
[0056] In this embodiment, the safety valve further includes a filter plate 24, which has multiple water passage holes. The valve core 21 and the inner wall of the housing 10 form a second water outlet channel 104. The filter plate 24 is installed in the second water outlet channel 104, and both the water passage holes and the second water outlet channel 104 are connected to the second water outlet 103. By installing a filter in the second water outlet channel 104, the water flow rate of the second water outlet 103 is reduced, thereby allowing the water to flow out slowly from the second water outlet 103, preventing excessive hot water from spraying out of the second water outlet 103 at a high speed, and thus greatly reducing the possibility of scalding the user.
[0057] The present invention also proposes a water outlet device, which includes a safety valve. The specific structure of the safety valve is as described in the above embodiments. The water outlet device in this application can be a shower head, a faucet, etc. Since the water outlet device of this application adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0058] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
