Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to an anti-scalding faucet. Background Technology

[0002] A faucet is a common name for a water valve, used to control the flow of water. When a faucet is used as a water heater or other device that produces hot water, the temperature of the hot water is transferred to the surface of the faucet, causing the casing to become hot and potentially scalding the user. Therefore, a new type of faucet is needed to solve this problem. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a scalding-proof faucet.

[0005] To achieve the above objectives, the technical solution of this utility model is: an anti-scalding faucet, comprising a main body, wherein a cold water inlet, a hot water inlet, and a water outlet are provided on the main body, a cold water channel and a mixing channel are provided inside the main body, a cold water chamber is provided at one end of the main body, the cold water chamber is connected to the cold water channel, an anti-scalding valve is provided in the cold water chamber, the hot water inlet is connected to the mixing channel through the anti-scalding valve, there is a gap between the anti-scalding valve and the cold water chamber, the cold water chamber is connected to the mixing channel through the anti-scalding valve, and the water outlet is connected to the mixing channel.

[0006] By adopting the above technical solution, after cold water enters the main body through the cold water inlet, it will enter the cold water chamber through the cold water outlet, fill the cold water chamber, and then enter the anti-scalding valve. Hot water will directly enter the anti-scalding valve, mix with the cold water, and then be discharged into the mixing channel, and finally discharged through the outlet. In this way, direct contact between the main body and hot water is avoided. Since the anti-scalding valve is placed in the cold water chamber, it is surrounded by cold water, thereby preventing the heat of the high-temperature hot water from being transferred to the shell, thus achieving the anti-scalding effect.

[0007] Preferably, the anti-scalding valve includes an anti-scalding outer shell and a thermostatic valve core. The thermostatic valve core is fixedly connected to the main body and has an inlet 1 and an inlet 2. The anti-scalding outer shell covers the inlet 2 and the inlet 1 of the thermostatic valve core. The anti-scalding valve body has a connecting hole and a connecting port. The inlet 2 is connected to the hot water outlet through the connecting hole, and the inlet 1 is connected to the cold water chamber through the connecting port. The anti-scalding outer shell is fixedly connected to the main body through a connecting mechanism. This utility model's anti-scalding outer shell covers the thermostatic valve core, connecting it to the hot water outlet through the connecting hole and to the cold water chamber through the connecting port. This further isolates the heat of the hot water from the main body, further enhancing the anti-scalding effect. The thermostatic valve core then controls the temperature.

[0008] Preferably, the connecting mechanism includes a connector, a connecting seat, and a stud. The connector is fixedly connected to the anti-scalding shell, the connecting seat is fixedly connected to the main body, and the stud passes through the connecting seat and is threadedly connected to the connector. In this invention, when installing the anti-scalding valve, the axial positioning of the valve is achieved by the mutual abutment between the connector and the connecting seat when the valve is inserted into the main body. The circumferential positioning of the valve is achieved by the stud passing through the connecting seat and being threadedly connected to the connector. This method facilitates the assembly of the anti-scalding shell.

[0009] Preferably, the thermostatic valve core has an adjustment knob, and the main body is provided with a temperature adjustment handle. The temperature adjustment handle is connected to the adjustment knob via a transmission mechanism, and the thermostatic valve core is provided with a limiting mechanism to restrict the rotation of the temperature adjustment handle. This invention utilizes the temperature adjustment handle to enclose the adjustment knob of the thermostatic valve core, integrating it with the appearance of the main body, making the faucet more aesthetically pleasing and easier to operate. The limiting mechanism restricts the rotation of the temperature adjustment handle, thereby limiting the maximum temperature of the water output, ensuring that the temperature inside the thermostatic valve core does not exceed a certain value, further enhancing the anti-scalding effect.

[0010] Preferably, the transmission mechanism includes a transmission sleeve and a fixing bolt. The adjusting knob is connected to the transmission sleeve via a spline, and the transmission sleeve is connected to the temperature control handle via a spline. The fixing bolt passes through the temperature control handle and the transmission sleeve and is threadedly connected to the adjusting knob. This invention utilizes the transmission sleeve to increase the size of the spline teeth that contact the temperature control handle, thereby increasing the contact area during temperature control handle transmission and preventing the spline teeth on the thermostatic valve core's adjusting knob from being too small and failing after the temperature control handle wears down.

[0011] Preferably, the limiting mechanism includes a button, an elastic element, a limiting rod, and a limiting ring. The limiting ring is fixedly connected to the thermostatic valve core, the button is slidably connected to the temperature control handle, the elastic element is disposed between the temperature control handle and the button, the limiting rod is fixedly connected to the button, and a blocking element is fixedly connected to the limiting ring, with the limiting rod abutting against the blocking element. Under the elastic force of the elastic element, the limiting rod maintains contact with the blocking element, thereby restricting the rotation of the temperature control handle in one direction. This prevents the adjustment knob from rotating in the direction of increasing temperature, thus fixing the maximum temperature. Simultaneously, the direction of decreasing temperature can be rotated normally. When it is necessary to further increase the temperature, the button can be pushed to make the limiting rod avoid the blocking element, at which point the rotation of the temperature control handle is unrestricted, and the temperature can be adjusted normally.

[0012] Preferably, the mixing channel is connected to the water outlet via a switching valve, and the switching valve is fixedly connected to the main body. This invention utilizes a switching valve to control the water output, allowing it to be turned off or on and the water flow rate to be adjusted.

[0013] Preferably, the switch valve has a control knob, and the control knob is tractively connected to a switch handle. This invention utilizes the switch handle to enclose the adjustment knob of the thermostatic valve core, integrating it seamlessly with the main body's appearance, making the faucet more aesthetically pleasing and easier to operate.

[0014] Preferably, the cold water inlet, hot water inlet, and water outlet are respectively threadedly connected to a hot water pipe, a cold water pipe, and a water outlet pipe. This invention utilizes the hot water pipe, cold water pipe, and water outlet pipe to facilitate connection of the cold water inlet, hot water inlet, and water outlet to external pipes.

[0015] Preferably, the anti-scalding outer shell is provided with a slot, and the connecting hole is opened at the bottom of the slot, into which the hot water pipe is inserted. This invention, by inserting the hot water pipe into the slot, achieves a better seal between the hot water pipe and the anti-scalding outer shell.

[0016] In summary, the beneficial effects of this utility model are:

[0017] 1. The anti-scalding valve is placed inside the cold water chamber and is surrounded by cold water, which prevents the heat of the hot water from being transferred to the shell, thus achieving the anti-scalding effect.

[0018] 2. The anti-scalding outer shell covers the thermostatic valve core and the inlet for hot water. It is connected to the hot water outlet through the connecting hole on it, which can further isolate the heat of the hot water from the main body and further enhance the anti-scalding effect. The thermostatic valve core realizes temperature control.

[0019] 3. The limiting mechanism can restrict the rotation of the temperature control handle, thereby limiting the maximum temperature of the water output, so that the temperature inside the thermostatic valve core does not exceed a certain value, further enhancing the anti-scalding effect.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0032] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0035] like Figure 1-4 As shown, an anti-scalding faucet includes a main body 1, on which a cold water inlet 2, a hot water inlet 3, and a water outlet 4 are provided. A cold water channel 5 and a mixing channel 6 are provided inside the main body 1. A cold water chamber 7 is provided at one end of the main body 1, and the cold water chamber 7 is connected to the cold water channel 5. An anti-scalding valve is provided in the cold water chamber 7. The hot water inlet 3 is connected to the mixing channel 6 through the anti-scalding valve. There is a gap 8 between the anti-scalding valve and the cold water chamber 7. The cold water chamber 7 is connected to the mixing channel 6 through the anti-scalding valve. The water outlet 4 is connected to the mixing channel 6.

[0036] By adopting the above technical solution, after cold water enters the main body 1 through the cold water inlet 2, it will flow into the cold water chamber 7, fill the cold water chamber 7, and enter the anti-scalding valve. Hot water will directly enter the anti-scalding valve, mix with the cold water, and then be discharged into the mixing channel 6, and finally discharged through the outlet 4. In this way, direct contact between the main body 1 and hot water is avoided. Since the anti-scalding valve is placed in the cold water chamber 7, it is surrounded by cold water, thereby preventing the heat of the high-temperature hot water from being transferred to the shell, thus achieving the anti-scalding effect.

[0037] The anti-scalding valve includes an anti-scalding outer shell 9 and a thermostatic valve core 10. The thermostatic valve core 10 is fixedly connected to the main body 1. The thermostatic valve core 10 has an inlet 11 and an inlet 22. The anti-scalding outer shell 9 covers the inlet 22 and inlet 11 of the thermostatic valve core 10. The anti-scalding valve body has a connecting hole 27 and a connecting port 30. Inlet 22 is connected to the hot water port 3 through the connecting hole 27, and inlet 11 is connected to the cold water chamber 7 through the connecting port 30. The anti-scalding outer shell 9 is fixedly connected to the main body 1 through a connecting mechanism. The anti-scalding outer shell 9 covers the thermostatic valve core 10 and connects to the hot water port 3 through the connecting hole 27 and the cold water chamber 7 through the connecting port 30. This further isolates the heat of the hot water from the main body 1, further enhancing the anti-scalding effect. The thermostatic valve core 10 controls the temperature.

[0038] The connecting mechanism includes a connector 13, a connecting seat 14, and a stud 15. The connector 13 is fixedly connected to the anti-scalding outer shell 9, the connecting seat 14 is fixedly connected to the main body 1, and the stud 15 passes through the connecting seat 14 and is threadedly connected to the connector 13. When installing the anti-scalding valve, the anti-scalding valve can be axially positioned by the mutual abutment between the connector 13 and the connecting seat 14 when inserted into the main body 1. The anti-scalding valve is circumferentially positioned by the stud 15 passing through the connecting seat 14 and being threadedly connected to the connector 13. This facilitates the assembly of the anti-scalding outer shell 9.

[0039] The thermostatic valve core 10 has an adjustment knob 29, and the main body 1 is equipped with a temperature control handle 28. The temperature control handle 28 is connected to the adjustment knob 29 via a transmission mechanism. The thermostatic valve core 10 is equipped with a limiting mechanism to restrict the rotation of the temperature control handle 28. By using the temperature control handle 28 to enclose the adjustment knob 29 of the thermostatic valve core 10, it is integrated with the appearance of the main body 1, making the faucet more aesthetically pleasing and easier to operate. The limiting mechanism can restrict the rotation of the temperature control handle 28, thereby limiting the maximum temperature of the water output, ensuring that the temperature inside the thermostatic valve core 10 does not exceed a certain value, further enhancing the anti-scalding effect.

[0040] The transmission mechanism includes a transmission sleeve 16 and a fixing bolt 17. The adjusting knob 29 is connected to the transmission sleeve 16 via a spline, and the transmission sleeve 16 is connected to the temperature control handle 28 via a spline. The fixing bolt 17 passes through the temperature control handle 28 and the transmission sleeve 16 and is threadedly connected to the adjusting knob 29. The transmission sleeve 16 increases the size of the spline teeth that contact the temperature control handle 28, increasing the contact area when the temperature control handle 28 is in motion. This prevents the spline teeth on the adjusting knob 29 of the thermostatic valve core 10 from being too small and failing after the temperature control handle 28 wears out.

[0041] The limiting mechanism includes a button 18, an elastic element 19, a limiting rod 20, and a limiting ring 21. The limiting ring 21 is fixedly connected to the thermostatic valve core 10. The button 18 is slidably connected to the temperature control handle 28. The elastic element 19 is disposed between the temperature control handle 28 and the button 18. The limiting rod 20 is fixedly connected to the button 18. A blocking element 22 is fixedly connected to the limiting ring 21, and the limiting rod 20 abuts against the blocking element 22. Under the action of the elastic force of the elastic element 19, the limiting rod 20 maintains mutual abutment with the blocking element 22, thereby restricting the rotation of the temperature control handle 28 in one direction. This prevents the adjusting knob 29 from rotating in the direction of increasing temperature, thus fixing the maximum temperature. At the same time, the direction of decreasing temperature can be rotated normally. When it is necessary to continue to increase the temperature, the button 18 can be pushed to make the limiting rod 20 avoid the blocking element 22. At this time, the rotation of the temperature control handle 28 is unrestricted, and the temperature can be increased normally.

[0042] The mixing channel 6 is connected to the outlet 4 via a switch valve 23, which is fixedly connected to the main body 1. The switch valve 23 can be used to control the water output, allowing it to be turned off or on and the water flow rate to be adjusted.

[0043] The switch valve 23 has a control knob 24, which is connected to a switch handle 25. The switch handle 25 encloses the adjustment knob 29 of the thermostatic valve core 10, integrating it with the appearance of the main body 1, making the faucet more aesthetically pleasing and easier to operate.

[0044] Cold water inlet 2, hot water inlet 3, and outlet 4 are respectively threaded with hot water pipe, cold water pipe, and outlet pipe. The hot water pipe, cold water pipe, and outlet pipe facilitate the connection of cold water inlet 2, hot water inlet 3, and outlet 4 to external pipes.

[0045] The anti-scalding outer shell 9 is provided with a slot 26, and a connecting hole 27 is opened at the bottom of the slot 26. The hot water pipe is inserted into the slot 26. By inserting the hot water pipe into the slot 26, the sealing between the hot water pipe and the anti-scalding outer shell 9 can be improved.

[0046] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
