[0037] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0038] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0039] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0040] This application provides an anti-scalding faucet and water dispenser to solve the problem that pressing the anti-scalding button can easily tip over the water dispenser. The following description will be provided in conjunction with the accompanying drawings.

[0041] This application provides an anti-scalding faucet, including a valve body 1, a water control mechanism 2, and an anti-scalding mechanism 3. The valve body 1 has a first valve chamber 11 and a second valve chamber 12, which communicate with each other. The water control mechanism 2 is at least partially disposed within the first valve chamber 11 to open or close it. The anti-scalding mechanism 3 includes an anti-scalding valve core 31 and a sliding key assembly 32. The anti-scalding valve core 31 is disposed within the second valve chamber 12 to open or close it. The sliding key assembly 32 is slidably connected to the valve body 1, and the anti-scalding valve core 31 is rotatably connected to the sliding key assembly 32.

[0042] By setting a water supply mechanism and an anti-scalding mechanism 3 on the valve body 1, hot water can only pass through the anti-scalding faucet when the water control mechanism 2 opens the first valve chamber 11 and the anti-scalding mechanism 3 opens the second valve chamber 12. By sliding the sliding key assembly 32 to the valve body 1, the user can control the anti-scalding valve core 31 to open or close the second valve chamber 12 by sliding the sliding key 321, which reduces the occurrence of water dispenser tipping over due to pressing the anti-scalding button 238 and solves the problem that pressing the anti-scalding button 238 can easily push the water dispenser over.

[0043] In this embodiment, an inlet pipe 13 and an outlet pipe 14 are integrally formed on the valve body 1. The inlet pipe 13 is connected to the first valve chamber 11, and the outlet pipe 14 is connected to the second valve chamber 12, so that hot water can sequentially enter the first valve chamber 11 and the second valve chamber 12 from the inlet pipe 13, and then be discharged from the outlet pipe 14. In some embodiments of this application, the inlet pipe 13 is connected to the second valve chamber 12, and the outlet pipe 14 is connected to the first valve chamber 11, so that hot water can sequentially enter the second valve chamber 12 and the first valve chamber 11 from the inlet pipe 13, and then be discharged from the outlet pipe 14.

[0044] A connecting hole 15 is provided inside the valve body 1, through which the first valve chamber 11 communicates with the second valve chamber 12. In this embodiment, the second valve chamber 12 is located below the first valve chamber 11, so that when the water supply mechanism opens the first valve chamber 11, the water in the first valve chamber 11 can flow into the second valve chamber 12 under the action of gravity through the connecting hole 15. The water outlet pipe 14 is integrally formed at the bottom of the valve body 1, so that when the anti-scalding valve core 31 opens the second valve chamber 12, the water in the second valve chamber 12 can be discharged through the water outlet pipe 14 under the action of gravity.

[0045] Furthermore, by setting a first valve chamber 11 and a second valve chamber 12 that are interconnected on the valve body 1, and by controlling the opening or closing of the first valve chamber 11 through the water supply mechanism and the opening or closing of the second valve chamber 12 through the anti-scalding mechanism 3, the user can control the water supply mechanism and the anti-scalding mechanism 3 in any order to turn on the anti-scalding faucet. This avoids water dispensing failures caused by the need to control the water supply mechanism and the anti-scalding mechanism 3 in a specific order to turn on the anti-scalding faucet, simplifies the operation of the anti-scalding faucet, and improves the applicability and inclusiveness of the anti-scalding faucet.

[0046] The anti-scalding valve core 31 is used to open or close the connection between the second valve chamber 12 and the water outlet pipe 14, thereby opening or closing the second valve chamber 12. The anti-scalding valve core 31 includes an anti-scalding sealing sleeve 311, an anti-scalding valve stem 312, an anti-scalding spring 313, and an anti-scalding sealing cap 314. An anti-scalding mounting hole 315 is provided on the valve body 1, which communicates with the second valve chamber 12, so that the anti-scalding sealing sleeve 311, the anti-scalding valve stem 312, and the anti-scalding spring 313 can be inserted into the second valve chamber 12 through the anti-scalding mounting hole 315. The anti-scalding sealing sleeve 311 is disposed in the second valve chamber 12, and an anti-scalding receiving groove is provided on the anti-scalding sealing sleeve 311. In this embodiment, both the anti-scalding receiving groove and the anti-scalding mounting hole 315 are arranged facing upwards. The anti-scalding sealing sleeve 311 includes a first anti-scalding part 3111 and a second anti-scalding part 3112 connected in sequence. The first anti-scalding part 3111 is press-fitted with the cavity wall of the second valve chamber 12 to achieve a fixed connection between the anti-scalding sealing sleeve 311 and the valve body 1. The second anti-scalding part 3112 abuts against the end of the water outlet pipe 14 to block the second valve chamber 12 from the water outlet pipe 14, so as to realize the opening or closing of the second valve chamber 12.

[0047] One end of the anti-scalding valve rod 312 extends into the anti-scalding receiving groove, and the end of the anti-scalding valve rod 312 extending into the anti-scalding receiving groove is fixedly connected to the anti-scalding sealing sleeve 311. The other end of the anti-scalding valve rod 312 passes through the anti-scalding sealing cover 314, and the sliding key assembly 32 is rotatably connected to the end of the anti-scalding valve rod 312 that passes through the anti-scalding sealing cover 314. Specifically, the anti-scalding valve rod 312 includes an anti-scalding rod body 3121, a first anti-scalding limiting plate 3122, and a second anti-scalding limiting plate 3123. The first anti-scalding limiting plate 3122 and the second anti-scalding limiting plate 3123 are spaced and sleeved on one end of the anti-scalding rod body 3121. An anti-scalding locking block 3113 is integrally formed on the second anti-scalding part 3112, and the anti-scalding locking block 3113 is locked and fixed between the first anti-scalding limiting plate 3122 and the second anti-scalding limiting plate 3123. The anti-scalding spring 313 is housed in the anti-scalding receiving groove. One end of the anti-scalding spring 313 abuts against the first anti-scalding limiting plate 3122, and the other end abuts against the anti-scalding sealing cover 314. The anti-scalding spring 313 applies a force to the anti-scalding valve rod 312 in the direction of the water outlet pipe 14, so as to drive the anti-scalding valve rod 312 to drive the second anti-scalding part 3112 to abut tightly against the end of the water outlet pipe 14, and the second valve chamber 12 can be kept in the closed state.

[0048] In this embodiment, the anti-scalding sealing sleeve 311 is made of elastic material. By using elastic material to make the anti-scalding sealing sleeve 311, it is not only beneficial for the second anti-scalding part 3112 to fit tightly against the end of the water outlet pipe 14, thus improving the blocking effect between the second valve chamber 12 and the water outlet pipe 14, but also beneficial for the second anti-scalding part 3112 to deform when the anti-scalding valve rod 312 is subjected to force and moves upward, so as to realize the connection between the second valve chamber 12 and the water outlet pipe 14, thereby opening the second valve chamber 12.

[0049] The sliding key assembly 32 is used by the user to control the position of the anti-scalding valve stem 312, thereby controlling the opening or closing of the second valve chamber 12. The sliding key assembly 32 includes a sliding key 321, a connecting rod 322, and a return spring 323. A mounting block 16 is integrally formed on the valve body 1. A mounting groove 161 is formed on the mounting block 16. A mounting post 162 is integrally formed on the groove wall of the mounting groove 161. The return spring 323 is sleeved on the mounting post 162. One end of the return spring 323 abuts against the groove wall of the mounting groove 161, and the other end of the return spring 323 abuts against the end of the sliding key 321 that extends into the mounting groove 161. The return spring 323 is used to apply a vertically upward force to the sliding key 321. One end of the sliding key 321 extends into the mounting groove 161, and the sliding key 321 slides and engages with the mounting groove 161. In this embodiment, the mounting groove 161 extends vertically so that the sliding key 321 can slide vertically relative to the valve body 1. By making the sliding key 321 slide and engage with the mounting groove 161, it is beneficial to limit the sliding direction of the sliding key 321, thereby improving the stability of the sliding of the sliding key 321.

[0050] The sliding key 321 includes a sliding key body 3211, a connecting part 3212, and a sliding part 3213. The connecting part 3212 is integrally formed on the top of the sliding key body 3211. The connecting rod 322 is rotatably connected to the connecting part 3212 via a pin. The sliding part 3213 is integrally formed on the side of the sliding key body 3211 near the mounting block 16. The mounting block 16 has a notch for the connecting part 3212 to extend out of the mounting groove 161. The sliding part 3213 is provided with a sliding block 3214. The groove wall of the mounting groove 161 has a sliding groove 163 that slides and engages with the sliding block 3214. Through the sliding engagement of the sliding block 3214 and the sliding groove 163, the sliding engagement between the sliding key 321 and the mounting block 16 can be realized. The connecting rod 322 has a first connecting end 3221, a second connecting end 3222 and a fulcrum end 3223. The first connecting end 3221 is rotatably connected to the connecting part 3212 by a pin. The second connecting end 3222 is rotatably connected to the anti-scalding valve rod 312 by a pin. The fulcrum end 3223 abuts against the valve body 1.

[0051] When the sliding key 321 is not subjected to external force, the return spring 323 pushes the sliding key 321 up, and the anti-scalding spring 313 applies a downward force to the anti-scalding valve rod 312 to drive the anti-scalding valve rod 312 to tightly abut against the end of the water outlet pipe 14, thus closing the second valve chamber 12. When the sliding key 321 is subjected to external force and slides downward, the connecting part 3212 drives the first connecting end 3221 of the connecting rod 322 to move downward, and the second connecting end 3222 of the connecting rod 322 moves upward under the action of the fulcrum end 3223 of the connecting rod 322. The upward movement of the second connecting end 3222 drives the anti-scalding valve rod 312 to move upward, thereby causing the second anti-scalding part 3112 to deform, realizing the connection between the second valve chamber 12 and the water outlet pipe 14, and opening the second valve chamber 12.

[0052] The water control mechanism 2 includes a water control valve core 21 and a cup push assembly 22. The water control valve core 21 is disposed in the first valve chamber 11. The cup push assembly 22 is rotatably connected to the water control valve core 21 so as to open or close the first valve chamber 11 when the cup push assembly 22 rotates.

[0053] The water control valve core 21 is used to open or close the connection between the first valve chamber 11 and the water outlet pipe 14, thereby opening or closing the first valve chamber 11. The water control valve core 21 includes a water control sealing sleeve 211, a water control valve stem 212, a water control spring 213, and a water control sealing cover 214. A water control mounting hole 215 is provided on the valve body 1, which communicates with the first valve chamber 11, so that the water control sealing sleeve 211, the water control valve stem 212, and the water control spring 213 can be inserted into the first valve chamber 11 through the water control mounting hole 215. The water control sealing sleeve 211 is disposed in the first valve chamber 11, and a water control receiving groove is provided on the water control sealing sleeve 211. In this embodiment, both the water control receiving groove and the water control mounting hole 215 are arranged facing upwards. The water control sealing sleeve 211 includes a first water control part 2111 and a second water control part 2112 connected in sequence. The first water control part 2111 is press-fitted with the cavity wall of the first valve cavity 11 to achieve a fixed connection between the water control sealing sleeve 211 and the valve body 1. The second water control part 2112 abuts against the end of the water outlet pipe 14 to block the connection between the first valve cavity 11 and the water outlet pipe 14, thereby realizing the opening or closing of the first valve cavity 11.

[0054] One end of the water control valve rod 212 extends into the water control receiving groove, and the end of the water control valve rod 212 extending into the water control receiving groove is fixedly connected to the water control sealing sleeve 211. The other end of the water control valve rod 212 passes through the water control sealing cover 214, and the sliding key assembly 32 is rotatably connected to the end of the water control valve rod 212 that passes through the water control sealing cover 214. Specifically, the water control valve rod 212 includes a water control rod body 2121, a first water control limiting plate 2122, and a second water control limiting plate 2123. The first water control limiting plate 2122 and the second water control limiting plate 2123 are spaced and sleeved on one end of the water control rod body 2121. A water control latching block 2113 is integrally formed on the second water control part 2112, and the water control latching block 2113 is engaged and fixed between the first water control limiting plate 2122 and the second water control limiting plate 2123. The water control spring 213 is housed in the water control receiving groove. One end of the water control spring 213 abuts against the first water control limiting plate 2122, and the other end abuts against the water control sealing cover 214. The water control spring 213 applies a force to the water control valve rod 212 in the direction of the water outlet pipe 14, so as to drive the water control valve rod 212 to drive the second water control part 2112 to abut tightly against the end of the water outlet pipe 14, and the first valve chamber 11 can be kept in the closed state.

[0055] In this embodiment, the water control sealing sleeve 211 is made of elastic material. By using elastic material to make the water control sealing sleeve 211, it is not only beneficial for the second water control part 2112 to fit tightly against the end of the water outlet pipe 14, thus improving the blocking effect between the first valve chamber 11 and the water outlet pipe 14, but also beneficial for the second water control part 2112 to deform when the water control valve rod 212 is subjected to force and moves upward, so as to realize the connection between the first valve chamber 11 and the water outlet pipe 14, thereby opening the first valve chamber 11.

[0056] The cup push assembly 22 is used to control the position of the water control valve rod 212. The cup push assembly 22 includes a mounting base 221, a mounting plate 222, a connecting rod 223, and a cup push plate 224. The connecting rod 223 and the mounting base 221 are integrally formed on the bottom of the mounting plate 222. The mounting base 221 is rotatably connected to the water control valve core 21 via a pin. The cup push plate 224 is integrally formed on the end of the connecting rod 223 away from the mounting plate 222. The mounting base 221 includes a first mounting member 2211 and a second mounting member 2212, which are spaced apart. The end of the water control valve rod 212 away from the water control sealing sleeve 211 is inserted between the first mounting member 2211 and the second mounting member 2212. Both the first mounting member 2211 and the second mounting member 2212 are provided with pins that rotatably cooperate with the water control valve rod 212. The first mounting component 2211 is provided with a first support surface 2213 and a first support angle 2214, and the second mounting component 2212 is provided with a second support surface and a second support angle. In this embodiment, the distance from the core axis of the pin to the first support surface 2213 and the second support surface is the same, the distance from the core axis of the pin to the first support angle 2214 and the second support angle is the same, and the distance from the core axis of the pin to the first support surface 2213 is less than the distance from the core axis of the pin to the first support angle 2214, so that when the water control valve core 21 closes the first valve chamber 11, both the first support surface 2213 and the second support surface abut against the valve body 1, and when the water control valve core 21 opens the first valve chamber 11, both the first support angle 2214 and the second support angle abut against the valve body 1.

[0057] The cup push assembly 22 also includes a telescopic assembly 23, which is used to change the distance between the cup push plate 224 and the mounting plate 222, thereby meeting the needs of cups of different heights pushing the cup push plate 224. The telescopic assembly 23 includes a telescopic rod 231, a guide seat 232, an elastic buckle, a sliding frame 235, a push rod 236, and a connector 237. The elastic buckle includes a locking block 233 and a locking spring 234. A connecting hole 2231 is provided on the connecting rod 223, which extends through the bottom end of the connecting rod 223 along its length, and one end of the telescopic rod 231 extends into the connecting hole 2231. A receiving hole 2311 is provided on the telescopic rod 231, which extends through the telescopic rod 231 along its length.

[0058] The guide seat 232 covers the top opening of the receiving hole 2311. One end of the guide seat 232 extending into the receiving hole 2311 has a guide hole 2321, which is opened along the width direction of the telescopic rod 231. The locking block 233 is installed in the guide hole 2321 and slides with the guide hole 2321. One side of the locking block 233 has an integrally formed insertion part 2331. The telescopic rod 231 has an insertion hole 2312, and the insertion part 2331 passes through the insertion hole 2312. The locking spring 234 is housed in the receiving hole 2311. One end of the locking spring 234 abuts against the end of the locking block 233 away from the insertion part 2331, and the other end abuts against the hole wall of the receiving hole 2311 to drive the insertion part 2331 to extend out of the insertion hole 2312. Multiple locking holes 2232 are provided on the hole wall of the connecting hole 2231. In this embodiment, the number of locking holes 2232 is set to two. The two locking holes 2232 are opened sequentially along the length direction of the connecting rod 223. The insertion part 2331 is inserted and engaged with any locking hole 2232, which helps to limit the sliding of the telescopic rod 231 relative to the connecting rod 223.

[0059] The sliding frame 235 is located on the side of the locking block 233 away from the guide seat 232. The sliding frame 235 has an integrally formed slider 2351. The locking block 233 has a sliding groove 2332. The opening direction of the sliding groove 2332 forms an angle with the length direction of the telescopic rod 231 and the opening direction of the sliding groove 2332 forms an angle with the width direction of the telescopic rod 231. The slider 2351 slides and engages with the sliding groove 2332 so that when the sliding frame 235 moves toward the guide seat 232, it can drive the insertion part 2331 to disengage from the locking hole 2232, so that the telescopic rod 231 can slide relative to the connecting rod 223, thereby changing the distance between the cup push plate 224 and the valve body 1.

[0060] The push rod 236 is housed in the receiving hole 2311. One end of the push rod 236 abuts against the sliding frame 235, and the other end of the push rod 236 abuts against the connector 237. One end of the connector 237 extends into the receiving hole 2311 from the end of the telescopic rod 231 away from the guide seat 232. A sliding block 2371 is integrally formed on the connector 237. A through groove 2313 is formed on the wall of the receiving hole 2311 to slide and engage with the sliding block 2371, so that the connector 237 can slide relative to the telescopic rod 231 along the length direction of the telescopic rod 231.

[0061] The telescopic assembly 23 also includes a button spring 239 and a button 238. A sliding groove 2244 is provided on the cup push plate 224, with the opening of the sliding groove 2244 facing downward. One end of the button 238 extends into the sliding groove 2244 and slides in cooperation with the sliding groove 2244. The other end of the button 238 can extend out from the opening of the sliding groove 2244. The end of the connector 237 away from the push rod 236 passes through the cup push plate 224 and extends into the sliding groove 2244. The button 238 abuts against the end of the connector 237 away from the push rod 236. One end of the button spring 239 abuts against the groove wall of the sliding groove 2244, and the other end of the button spring 239 abuts against the side of the connector 237 away from the button 238. By pressing button 238 into sliding groove 2244, connector 237 moves upward relative to cup push plate 224. The upward movement of connector 237 drives push rod 236 to move upward. The upward movement of push rod 236 drives sliding frame 235 to move towards guide seat 232, causing insertion part 2331 to disengage from card hole 2232. This allows adjustment of the position of telescopic rod 231 relative to connecting rod 223, thereby realizing adjustment of the position of cup push plate 224 relative to valve body 1.

[0062] In addition, the cup pusher plate 224 includes a cup pusher upper plate 2241, a cup pusher middle plate 2242 and a cup pusher lower plate 2243 connected in sequence. By setting the cup pusher upper plate 2241, cup pusher middle plate 2242 and cup pusher lower plate 2243, it is beneficial to simplify the assembly of the button 238 with the cup pusher plate 224 and the connector 237 with the cup pusher plate 224, thereby improving the production efficiency of the cup pusher assembly 22.
