Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purification faucets, in particular to a pressurized boiling faucet for water purification machines. BACKGROUND

[0002] In the prior art, common instant heating faucets or instant heating drinking water devices usually use instant heating bodies (such as electric heating tubes, thick film heaters, etc.) to quickly heat the flowing water, so as to achieve the use experience of "instant heating and instant out". With the advantages of instant heating and no need to wait, the instant heating faucets and related instant heating drinking water devices are widely used in home, office and other scenes, and meet the needs of users to quickly obtain hot water. However, in actual use, the instant heating faucet and related instant heating drinking water device always has a core technical pain point, that is, it is difficult to achieve "true boiling" of hot water, and cannot provide boiling water that really reaches the boiling point for users.

[0003] Specifically, on the one hand, the waterway design of the traditional instant heating faucet is mainly straight-through or simple bending. The hot water is in a continuous flowing state in the pipeline before flowing out, and cannot accumulate and form a continuous rolling boiling phenomenon. Even if the water temperature reaches 100℃, due to the influence of the pressure and flow rate in the pipeline, the water often does not have obvious vaporization rolling, but is only high-temperature liquid water, rather than truly boiling water. On the other hand, the heated hot water is prone to heat loss during transmission, resulting in that the temperature of the outflowing hot water is always lower than the boiling point, and the use demand of users for boiling water cannot be met.

[0004] Therefore, how to design a faucet structure that can provide a dedicated boiling space for hot water, and through reasonable pressurization regulation, let the hot water really reach the boiling point and form a rolling boiling state during flowing, becomes a technical problem to be solved in the prior art. SUMMARY

[0005] The present application provides a pressurized boiling faucet for water purification machines, which can make hot water really reach the boiling point and form a rolling boiling state during flowing.

[0006] The technical scheme adopted by the present application is as follows: A pressurized boiling faucet for water purification machines, comprising: a housing having a housing body and a water outlet cantilever, the housing body extends longitudinally, and the water outlet cantilever is provided with a water outlet; a hot water pipeline comprising a water supply pipe longitudinally arranged in the housing body and a water outlet pipe arranged in the water outlet cantilever, the water inlet end of the water supply pipe being connected to an instant heating body, and the water outlet end of the water supply pipe being communicated with the water outlet pipe; a pressurization assembly comprising a connecting seat, a pressurization piece, and a boiling chamber, the connecting seat being provided at the bottom with a hot water inlet communicated with the boiling chamber, the hot water inlet being connected to the water outlet end of the water supply pipe, and the boiling chamber being provided with a hot water outlet connected to the water outlet pipe; The pressurizing member blocks the hot water inlet to pressurize the liquid in the water supply pipe and the instant heating body, and when the instant heating body is heated to the preset temperature, the pressure of the water supply pipe pushes the pressurizing member to open, so that the hot water boils and rolls in the boiling chamber.

[0007] In the scheme, the water flow is pressurized by the pressurizing assembly, so that the water is heated to a preset temperature (usually slightly higher than the normal pressure boiling point of 100 degrees, such as 102 degrees, 105 degrees, etc., affected by altitude, the preset temperature is not less than 80℃) in the instant heating body, so that the hot water reaches a saturated state in a high-pressure environment. When the pressurizing member is pushed open and the water flow enters the boiling chamber, the pressure is completely released, the hot water in the super-saturated state is instantly vaporized, and the rolling boiling phenomenon is formed. This "true boiling" design first pressurizes and stores energy, and then instantly releases pressure to boil, so that the hot water truly reaches the boiling point during the flow process and forms a rolling boiling state, providing users with a real and safe boiling water experience.

[0008] The top of the connecting seat is provided with a recess, the top surface of the recess has an open mouth, the open mouth is provided with a sealing cover, and the recess and the sealing cover form the boiling chamber.

[0009] In the scheme, the recess and the sealing cover form the boiling chamber, which can accurately build a sealed pressurized space to provide a stable pressure environment for boiling, avoid pressure leakage leading to boiling condition failure, and ensure that the hot water stably rolls and boils at the preset temperature. On the other hand, the design of the hot water inlet at the bottom and the outlet at the side wall promotes the flow of water from bottom to top, forms natural convection in the boiling chamber, enhances the rolling effect, and is beneficial to the realization of boiling.

[0010] The connecting seat is provided with a mounting area, and an upwardly arched sealing cover is arranged above the mounting area. The sealing cover is sealingly connected with the connecting seat to form the boiling chamber. The hot water inlet is arranged on the mounting area, and the hot water outlet is arranged on the side wall of the sealing cover.

[0011] In the scheme, the mounting area and the upwardly arched sealing cover are sealingly connected to form the boiling chamber. The upwardly arched structure provides a larger boiling space for the hot water, adapts to the volume change of the hot water during boiling, avoids overflow of the hot water due to boiling expansion, reduces pressure fluctuations caused by water flow impact, maintains a stable pressurized environment in the chamber, and ensures continuous boiling. The layout of the hot water inlet on the mounting area and the hot water outlet on the side wall of the sealing cover allows the hot water to form a smooth flow channel along the arched inner wall after entering the boiling chamber, increases the contact area between the hot water and the space in the chamber, and makes the boiling more uniform. At the same time, the arched sealing cover structure is beneficial to dispersing the water flow impact force during boiling, and improves the safety in use.

[0012] The water supply pipe supplies water from bottom to top, and after the water flow is deflected and reversed in the pressurization component, it flows out from the outlet pipe; the boiling chamber is located at the deflection and reversal point of the pressurization component, and the longitudinal water flow in the water supply pipe forms a rolling boiling at the top of the boiling chamber.

[0013] In this design, the flow reversal design within the pressurization component creates a local high-pressure zone at the reversal point, further enhancing the boiling trigger conditions and allowing the hot water to quickly enter the boiling state at the preset temperature. The boiling chamber is located at the flow reversal point to prevent the hot water from flowing out of the hot water outlet too quickly after entering from the hot water inlet. This design prolongs the boiling time of the hot water in the chamber and improves the boiling effect.

[0014] The boiling chamber is provided with a reversing channel that extends longitudinally along the side wall of the boiling chamber. The reversing channel has an inlet located above it and a hot water outlet located below the inlet. The inlet is higher than the hot water inlet of the boiling chamber.

[0015] In this design, the reversing channel extends longitudinally along the side wall of the boiling chamber, and its inlet is higher than the hot water inlet. This design allows the hot water to flow upwards after entering the boiling chamber, providing ample space and flow momentum for boiling and enabling the hot water to tumble more thoroughly. The layout of the inlet being higher than the hot water inlet prevents the hot water from flowing out directly as soon as it enters the chamber, ensuring the boiling effect. The longitudinally extending reversing channel guides the water flow in an orderly manner, reducing the interference of turbulence on the boiling effect. The vertical arrangement of the channel inlet and the hot water outlet allows the boiled hot water to flow out smoothly without affecting the boiling circulation within the chamber, ensuring that boiling occurs continuously and stably.

[0016] The ratio of the cross-sectional area of ​​the reversing channel to the cross-sectional area of ​​the hot water inlet is 0.7:1 to 0.9:1; the ratio of the cross-sectional area of ​​the reversing channel to the cross-sectional area of ​​the hot water outlet is 1:1.1 to 1:1.3.

[0017] In this design, the flow cross-sectional area gradients of the hot water inlet, reversing channel, and hot water outlet are amplified to achieve a slow release of pressure in the boiling chamber, resulting in optimal boiling effect. If the pressure release is too slow, the high pressure can easily cause deformation of components, and if the seals are not properly sealed, it can lead to hot water leakage. If the pressure release is too fast, the pressure accumulation is insufficient, the boiling effect is weak, and the purpose of the baffle outlet is diminished.

[0018] The pressurizing component is a gravity ball, which is installed inside the boiling chamber. The side wall of the boiling chamber has a flow gap. After the water supply pipe pressure pushes open the gravity ball, hot water flows through the flow gap to the hot water outlet; or... The pressurizing component is a spring pressure valve, which has a central flow channel. After the water supply pipe pressure opens the spring pressure valve, hot water flows from the central flow channel to the hot water outlet.

[0019] In this scheme, when the pressurizing piece adopts a gravity ball, automatic plugging of the hot water inlet is realized by relying on gravity, the structure is simple and reliable, no additional power control is needed, and the pressure change in the water supply pipe can be accurately responded to, when the pressure reaches the preset value, the gravity ball is pushed open, triggering boiling, ensuring the accuracy of the boiling opportunity; the design of the overflow gap makes the hot water evenly dispersed into the boiling bin, forming a soft rolling boiling state, avoiding boiling disorder caused by concentrated water flow impact, while ensuring the sufficiency of boiling, and the mechanical structure of the gravity ball is wear-resistant and less prone to failure, which can maintain the pressurized environment for a long time, ensuring the consistency of the boiling effect.

[0020] When the pressurizing piece adopts a spring pressure valve, the center flow channel design makes the hot water flow path smooth and has small resistance, which can quickly enter the boiling bin to realize rolling boiling; the spring elasticity force can be accurately adjusted to adapt to different boiling pressure requirements, and the trigger pressure can be flexibly set according to product design to expand the product application scenarios; the sealing performance of the spring pressure valve is excellent, which can effectively block the pressure leakage in the bin, ensure the pressurizing effect in the water supply pipe and the instant heater, and ensure the stable triggering of boiling, while the buffer effect of the spring can reduce the damage of water flow impact on the valve, prolong the service life, and ensure long-term stable boiling.

[0021] The faucet is provided with an instant heater, and the instant heater is longitudinally arranged in the shell body. The faucet is provided with an instant heater, and the instant heater is longitudinally arranged in the shell body.

[0022] In this scheme, when the instant heater is installed in the faucet, the path of hot water from the instant heater outlet to the water supply pipe is short, the heat loss is extremely low, the preset temperature required for boiling can be quickly reached, and the waiting time is shortened; the instant heater is directly connected with the water supply pipe, the pressure transmission is more direct, the pressure loss caused by long pipeline is avoided, the triggering efficiency of the pressurizing assembly on boiling is ensured, and the integrated design makes the faucet structure more compact, saves installation space, and reduces the leakage risk caused by external pipeline connection, ensuring the stability of the pressurized environment.

[0023] When the instant heater is installed outside the faucet, the instant heater can be individually maintained, repaired and replaced, different power instant heaters can be adapted according to user needs, the heating speed and boiling effect can be flexibly adjusted, and the product adaptability is improved; the external installation method reduces the structural complexity of the faucet, provides more layout space for core components such as the pressurizing assembly, and can avoid the influence of heat generated by the instant heater on other components inside the faucet, prolonging the service life of the whole product.

[0024] The faucet further comprises a cold water pipeline, and a bottom of the connecting seat is provided with an annular separation rib, which forms a central hot water interface and a cold water cavity surrounding the hot water interface, the hot water inlet communicates with the hot water interface, and the cold water pipeline communicates with the cold water cavity. A temperature sensor is mounted on a side wall of the connecting seat, and the temperature sensor detects the water temperature in the hot water interface.

[0025] In this scheme, the annular separation rib design realizes the physical separation of hot and cold water, avoids the interference of cold water with the pressurized environment on the hot water side, ensures the stability of the pressure in the water supply pipe and the boiling bin, and provides undisturbed conditions for boiling; the cooperation of the cold water cavity and the hot water cavity (boiling bin) can realize the mixing of hot and cold water, users can adjust the water temperature according to needs, enjoy boiling hot water, and flexibly adapt to different use scenarios such as washing and cleaning, thereby improving the practicality of the product; the temperature sensor can accurately feedback temperature data by detecting the water temperature in the hot water interface in real time, so that the control system can adjust the heating power of the instant heater, ensure that the water temperature accurately reaches the preset value of boiling, avoid boiling failure caused by excessively high or low water temperature, improve the use safety, avoid energy waste, and make the temperature control of boiling more accurate, thereby further optimizing the boiling effect.

[0026] A mounting hole is arranged on a top surface of the water outlet cantilever, a top of the boiling bin protrudes from the top surface of the water outlet cantilever from the mounting hole, and the top of the boiling bin is transparent and visible. A mounting hole is arranged on a top surface of the water outlet cantilever, a top of the boiling bin protrudes from the top surface of the water outlet cantilever from the mounting hole, and the top of the boiling bin is transparent and visible.

[0027] In this scheme, the top of the boiling bin is transparent, so that users can directly and intuitively observe the rolling boiling state of hot water in the bin, clearly confirm whether boiling is normally occurring, and enhance the trust in the use of the product; the design that the top of the boiling bin protrudes from the top surface of the water outlet cantilever expands the visible angle and makes observation more convenient, and the transparent material does not affect the pressure environment and boiling effect in the bin, thereby improving the interactive experience of the product on the basis of guaranteeing the core function and enabling users to directly and intuitively feel the advantages of boiling.

[0028] The outer cover is transparent and visible, the outer cover plays a protective role, can effectively block dust and foreign matter from entering the boiling bin, guarantees the stable boiling, and does not block the observation line of sight, and the outer cover can effectively insulate heat, thereby guaranteeing the safety of users.

[0029] Compared with the prior art, the application has the following beneficial effects: The water flow is pressurized by the pressurizing assembly, so that the water is heated to a preset temperature in the instant heating body, so that the hot water reaches a saturated state in a high-pressure environment. When the pressurizing part is pushed open, the water flow enters the boiling bin, and the pressure is completely released. The hot water in the supersaturated state is vaporized instantaneously, forming a rolling boiling phenomenon. The application makes the hot water truly reach the boiling point during the flow process and form a rolling boiling state, providing users with a real and safe boiling water experience.

DETAILED DESCRIPTION

[0032] In order to more clearly illustrate the overall concept of the present application, the following detailed description will be made in conjunction with the accompanying drawings.

[0033] In the following description, a number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced without the specific details, other than in the examples, and therefore the scope of the present application is not limited to the specific embodiments disclosed.

[0034] Reference Figures 1 to 7 The present application provides a pressurized boiling faucet for water purifiers, comprising a housing 1, a hot water pipeline 2 and a pressurizing assembly 3. The housing 1 has a housing body 11 and a water outlet cantilever 12, the housing body 11 extends longitudinally, and the water outlet cantilever 12 extends transversely, the housing body 11 and the water outlet cantilever 12 provide installation space for the hot water pipeline 2, the pressurizing assembly 3 and other components, and the top of the water outlet cantilever 12 can be used for display and human-computer interaction.

[0035] The hot water pipeline 2 comprises a water supply pipe 21 longitudinally arranged in the housing body 11 and a water outlet pipe 22 arranged in the water outlet cantilever 12, the water outlet cantilever 12 is provided with a water outlet 121, and the end of the water outlet pipe 22 extends to the water outlet 121 to facilitate water drainage. The water inlet end of the water supply pipe 21 is connected to the instant heater 4, and the water outlet end of the water supply pipe 21 is communicated with the water outlet pipe 22, after the water is heated by the instant heater 4, it passes through the water supply pipe 21 and the water outlet pipe 22 in turn, and is finally discharged through the water outlet 121. In actual arrangement, the end of the water outlet cantilever 12 can also be additionally provided with a water outlet box 5 for water type arrangement and air exhaust, the water outlet of the water outlet box 5 is correspondingly arranged with the water outlet 121, the water outlet pipe 22 is communicated with the water outlet box 5, and the water flowing through the water outlet pipe 22 will finally be discharged through the water outlet box 5.

[0036] The pressurizing assembly 3 comprises a connecting seat 31, a pressurizing piece 32 and a boiling bin 33, the bottom of the connecting seat 31 is provided with a hot water inlet 311 communicated with the boiling bin 33, the hot water inlet 311 is connected to the water outlet end of the water supply pipe 21, and the boiling bin 33 is provided with a hot water outlet 312 connected to the water outlet pipe 22.

[0037] The pressurizing piece 32 blocks the hot water inlet 311 to pressurize the liquid in the water supply pipe 21 and the instant heater 4, when the instant heater 4 is heated to a preset temperature, the pressure of the water supply pipe 21 pushes open the pressurizing piece 32, so that the hot water boils and rolls in the boiling bin 33.

[0038] This application utilizes a pressurizing component 3 to pressurize and depressurize the water flow. During pressurization, the water is heated to a preset temperature within the instantaneous heating element 4, causing the hot water to reach a saturated state under high pressure. This preset temperature is typically slightly higher than the normal boiling point by 100 degrees Celsius, such as 102 or 105 degrees Celsius. Due to altitude, the preset temperature is no lower than 80 degrees Celsius. During depressurization, the supersaturated hot water instantly vaporizes, resulting in a rolling boiling phenomenon. Specifically, the connecting seat 31 provides the foundation for the pressurizing component 32 and the boiling chamber 33. The boiling chamber 33 provides the environment for the rolling boiling of the liquid. The pressurizing component 32 seals the hot water inlet 311. Before the pressurizing component 32 is opened, the liquid in the water supply pipe 21 and the instantaneous heating element 4 remains under high pressure. The liquid eventually reaches a saturated state under high pressure. When a certain critical value (preset temperature) is exceeded, the pressurizing component 32 is opened, the pressure is completely released, and the supersaturated hot water instantly vaporizes, resulting in a rolling boiling phenomenon. This "true boiling" design first pressurizes and stores energy, then instantly releases pressure to boil, allowing the hot water to truly reach the boiling point and form a rolling boiling state during the flow process, providing users with a real and safe boiling water experience.

[0039] In actual use, the pressurized boiling faucet is paired with a water purifier. The filtration device inside the water purifier filters the raw water. The filtration device is connected to the inlet of the instant heating element 4 to deliver the filtered water to the instant heating element 4 for instant heating. Because the water flow rate and water pressure of the filtered water are small, the water supply power is not easy to create a boiling effect during the instant heating process. Therefore, the pressurization component 3 is set to pressurize the water in the instant heating element 4, and then combined with instantaneous pressure relief, a rolling boiling phenomenon is formed in the boiling chamber 33.

[0040] In other preferred embodiments, refer to Figures 3 to 6 The top of the connecting seat 31 is provided with a cavity 313, the top surface of the cavity 313 has an opening, and a sealing cover 34 is installed on the opening. The cavity 313 and the sealing cover 34 enclose each other to form a boiling chamber 33. The hot water inlet 311 is provided at the bottom of the cavity 313, and the hot water outlet 312 is provided on the side wall of the cavity 313.

[0041] In this embodiment, a boiling chamber 33 is constructed by enclosing a cavity 313 and a sealing cover 34 to provide a stable pressure environment for boiling. Specifically, the sealing cover 34 is placed on the cavity wall of the cavity 313. To ensure the sealing effect, at least one sealing groove 3131 is provided around the cavity wall of the cavity 313. A sealing ring is placed in the sealing groove 3131 to achieve a seal between the outer wall of the cavity 313 and the inner wall of the sealing cover 34, so as to construct a stable and sealed pressurized space, avoid pressure leakage that would cause the boiling conditions to fail, and ensure that the hot water boils stably at a preset temperature.

[0042] To further ensure the stability of the sealing cover 34 and the ease of installation, please refer to the following: Figure 6 andFigure 7 The bottom of the sealing cover 34 is provided with a skirt 341, and the connecting seat 31 is provided with a limiting groove 3143 matched with the skirt 341. The skirt 341 and the limiting groove 3143 can be designed as two groups, three groups or more, and the skirts 341 and the limiting grooves 3143 in each group are uniformly distributed in the axial direction. Specifically, the connecting seat 31 is provided with a buckle 314, and the limiting groove 3143 is formed in the buckle 314. The buckle 314 has a rotating port 3141 and a stop edge 3142 opposite to the rotating port 3141. The space between the rotating port 3141 and the stop edge 3142 is the limiting groove 3143. During installation, each skirt 341 falls into the space between adjacent buckles 314, and the sealing cover 34 is randomly rotated so that the stop edge 3142 enters from the rotating port 3141 until it abuts against the stop edge 3142. To prevent the stop edge 3142 from being pulled out in the reverse direction, a notch 3411 is arranged on the skirt 341, and a protruding rib 3144 is arranged in the limiting groove 3143. After the sealing cover 34 is rotated into place, the protruding rib 3144 is clamped into the notch 3411 to achieve reverse positioning.

[0043] In this embodiment, the hot water inlet 311 is located at the bottom, and the hot water outlet 312 is located at the side wall, which promotes the upward flow of water. The hot water enters from the hot water inlet 311 and rushes to the sealing cover 34, and then falls from a high place to form natural convection in the boiling chamber 33, thereby enhancing the rolling effect. In order to avoid the hot water rushing out of the hot water inlet 311 colliding with the falling hot water, causing water flow disorder and affecting the boiling effect, the top of the sealing cover 34 is designed as a concave shape, i.e., low in the middle and high on the periphery, forming a flow guide path. After the water flow enters from the hot water inlet 311 and rushes to the sealing cover 34, the water flow spreads to the periphery along the flow guide path and falls from the periphery of the sealing cover 34, successfully avoiding the water flow rushing in from the center hot water inlet 311, so that the rolling effect proceeds in an orderly manner.

[0044] In some alternative embodiments, the connecting seat 31 is provided with a mounting area, and the sealing cover 34 is arranged above the mounting area in an upward arch shape. The sealing cover 34 is sealingly connected with the connecting seat 31 to form the boiling chamber 33. The hot water inlet 311 is arranged on the mounting area, and the hot water outlet 312 is arranged on the side wall of the sealing cover 34.

[0045] In the foregoing embodiments, the recess cavity 313 structure serves as the main space of the boiling chamber 33. In this embodiment, the recess cavity 313 in the foregoing embodiments is cancelled, and the space in the upward arch-shaped sealing cover 34 serves as the main space of the boiling chamber 33. This design simplifies the structure of the connecting seat 31, and the upward arch-shaped structure of the sealing cover 34 provides more boiling space for hot water.

[0046] The hot water inlet 311 is arranged in the installation area, and the hot water outlet 312 is arranged in the side wall of the sealing cover 34, so that the hot water can form a smooth flow channel along the arched inner wall after entering the boiling bin 33, the contact area of the hot water with the space in the bin is increased, and boiling is more uniform; meanwhile, the arched structure of the sealing cover 34 is beneficial to dispersing the water flow impact force during boiling, and the use safety is improved.

[0047] In other preferred embodiments, referring to Figures 1 to 6 , the water flow direction in the water supply pipe 21 is from bottom to top, the water flow is changed direction in the pressurizing assembly 3 and then flows out from the water outlet pipe 22; the boiling bin 33 is arranged at the change direction position of the pressurizing assembly 3, and the longitudinal water flow in the water supply pipe 21 forms rolling boiling at the top of the boiling bin 33.

[0048] In this embodiment, the boiling bin 33 is arranged at the change direction position of the pressurizing assembly 3, the water flow is changed direction in the boiling bin 33 and then flows out from the water outlet pipe 22, that is, the water flow does not flow out immediately after entering the boiling bin 33, but forms a rotating and changing direction path from bottom to top and then from top to bottom, which avoids the hot water from flowing out from the hot water outlet 312 quickly after entering the hot water inlet 311, the design prolongs the boiling time of the hot water in the bin and improves the boiling effect. Meanwhile, the change direction design avoids the pressure in the bin from being released too quickly, and ensures the rolling boiling effect of the hot water.

[0049] In order to adapt to the structure of the longitudinally extending shell body 11 and the transversely extending water outlet cantilever 12, the pressurizing assembly 3 is arranged at the connection position of the shell body 11 and the water outlet cantilever 12, so as to ensure that the water flow directly enters the transverse water outlet pipe 22 after being changed direction in the boiling bin 33 and is discharged along the transverse water outlet pipe 22 without resistance, that is, the water flow only changes direction once in the boiling bin 33.

[0050] In other preferred embodiments, referring to Figure 5 and Figure 6 , the boiling bin 33 is provided with a change direction channel 351, the change direction channel 351 extends longitudinally along the side wall of the boiling bin 33, the change direction channel 351 has an inlet 3511 above the change direction channel 351 and a hot water outlet 312 below the inlet 3511, and the inlet 3511 is higher than the hot water inlet 311 of the boiling bin 33.

[0051] In this embodiment, the change direction channel 351 extends longitudinally along the side wall of the boiling bin 33, and the inlet 3511 is higher than the hot water inlet 311, which provides a stable change direction path for the change direction, the water flow enters the change direction channel 351 through the top inlet 3511 after entering the bottom hot water inlet 311 in the boiling bin 33, and then flows to the water outlet pipe 22 through the lower hot water outlet 312 after rotating and changing direction.

[0052] The reversing channel 351 is specifically formed in the surrounding rib 35 arranged around the hot water outlet 312. To ensure that the liquid has sufficient rolling boiling space and flow power, the surrounding rib 35 extends upward to a position close to the sealing cover 34. The excessively high design of the inlet 3511 can avoid the hot water from flowing out directly after entering the tank, thereby ensuring the boiling effect. The longitudinally extending reversing channel 351 guides the water flow to flow in an orderly manner, reduces the interference of turbulence on the boiling effect, and the upper and lower layout of the inlet 3511 and the hot water outlet 312 enables the hot water after boiling to flow out smoothly without affecting the boiling circulation in the tank.

[0053] In further preferred embodiments, the ratio of the cross-sectional area of the reversing channel 351 to the cross-sectional area of the hot water inlet 311 is 0.7:1-0.9:1, and the ratio of the cross-sectional area of the reversing channel 351 to the cross-sectional area of the hot water outlet 312 is 1:1.1-1:1.3.

[0054] The flow cross-sectional area gradient of the hot water inlet 311, the reversing channel 351 and the hot water outlet 312 in this embodiment is amplified, which realizes slow pressure release of the hot water in the boiling tank 33 and achieves optimal boiling effect. If the pressure is released too slowly, high pressure can cause deformation of parts, and if the sealing of the sealing member is poor, it can further cause hot water leakage. If the pressure is released too quickly, the pressure is not sufficient, the boiling effect is weak, and the deflection of the water is weakened.

[0055] In other preferred embodiments, with reference to Figures 3 to 5 The pressurizing member 32 is a gravity ball, which is installed in the boiling tank 33. The side wall of the boiling tank 33 is provided with an overflow gap 331. After the gravity ball is pushed open by the pressure of the water supply pipe 21, the hot water flows from the overflow gap 331 to the hot water outlet 312.

[0056] This embodiment realizes automatic plugging of the hot water inlet 311 by relying on the gravity of the gravity ball, which is simple and reliable in structure and does not require additional power control. It can accurately respond to the pressure change in the water supply pipe 21. When the pressure reaches the preset value, the gravity ball is pushed open, triggering boiling, and ensuring the accuracy of the boiling opportunity. Specifically, a circle of spaced-apart blocking ribs 36 is arranged around the hot water inlet 311 in the boiling tank 33. One end of the blocking rib 36 is connected with the inner wall of the boiling tank 33, and the other end extends towards the hot water inlet 311 to form a gravity tank 361 for accommodating the gravity ball. The adjacent blocking ribs 36 form an overflow gap 331, and the hot water flows into the boiling tank 33 from the overflow gap 331 after pushing open the gravity ball. In addition, the gravity tank 361 can radially position the gravity ball to avoid the gravity ball from deviating and being stuck under the impact of the water flow, thereby ensuring that the gravity ball always moves in the vertical direction to provide stable water flow pressure.

[0057] In some alternative embodiments, the pressurizing member 32 is a spring pressure valve. The spring pressure valve has a central flow channel. After the spring pressure valve is pushed open by the pressure of the water supply pipe 21, the hot water flows from the central flow channel to the hot water outlet 312.

[0058] The central flow channel design of the embodiment makes the hot water flow path smooth and small in resistance, enabling rapid entry into the boiling bin 33 to achieve rolling boiling. The elastic force of the spring can be accurately adjusted to adapt to different boiling pressure requirements, and the trigger pressure can be flexibly set according to product design to expand the product application scenarios. The spring pressure valve is of an existing structure, and therefore the specific structure thereof is not shown.

[0059] In other preferred embodiments, with reference to Figure 1 and Figure 2 , the instant heater 4 is installed in the faucet, and the instant heater 4 is longitudinally arranged in the shell body 11. The instant heater 4 has a water inlet at the lower portion and a water outlet at the upper portion. The water outlet of the instant heater 4 is connected to the water inlet end of the water supply pipe 21.

[0060] In the embodiment, the instant heater 4 is longitudinally arranged in the shell body 11, which shortens the path of hot water from the water outlet of the instant heater 4 to the water supply pipe 21, has extremely low heat loss, can quickly reach the preset temperature required for boiling, and shortens the waiting time. The instant heater 4 is directly connected to the water supply pipe 21, which makes the pressure transmission more direct, avoids pressure loss caused by long pipeline, and integrates the design to make the faucet structure more compact, save installation space, and reduce the leakage risk caused by external pipeline connection, thereby ensuring the stability of the pressurized environment.

[0061] In some alternative embodiments, the instant heater 4 is installed outside the faucet, and the water outlet of the instant heater 4 is connected to the water inlet end of the water supply pipe 21.

[0062] In the embodiment, the instant heater 4 is installed outside the faucet, for example, the instant heater 4 is arranged in the body of the water purifier, which facilitates the separate maintenance, repair and replacement of the instant heater 4, can adapt different power instant heaters 4 according to user needs, flexibly adjust the heating speed and boiling effect, and improve the product adaptability. The external installation method reduces the structural complexity of the faucet, provides more layout space for core components such as the pressurizing assembly 3, and can avoid the influence of heat generated by the instant heater 4 on other components inside the faucet during operation, thereby prolonging the service life of the overall product.

[0063] In other preferred embodiments, with reference to Figure 1 , Figure 5 and Figure 6 , the faucet further comprises a cold water pipeline 6. The bottom of the connecting seat 31 is provided with a ring-shaped separation rib 315, which forms a central hot water interface 316 and a cold water cavity 37 surrounding the hot water interface 316. The hot water inlet 311 communicates with the hot water interface 316, and the cold water pipeline 6 communicates with the cold water cavity 37.

[0064] The boiling cavity 33 (hot water cavity) above the connecting seat 31 and the cold water cavity 37 below the connecting seat 31 are separated by the partition rib 315. The hot water cavity and the cold water cavity 37 are arranged vertically, which greatly saves the horizontal installation space in the shell 1, and makes the overall structure of the faucet more compact. The hot water cavity and the cold water cavity 37 are vertically separated by physical structure, reducing heat conduction between cold and hot fluids, avoiding cold water interfering with the pressurized environment on the hot water side, and ensuring the stability of the pressure in the water supply pipe 21 and the boiling cavity 33, providing undisturbed conditions for boiling. The cooperation of the cold water cavity and the hot water cavity can realize the mixing of cold and hot water, and users can adjust the water temperature according to their needs, enjoy boiling hot water, and flexibly adapt to different use scenarios such as washing and cleaning, improving the practicality of the product.

[0065] The temperature sensor 7 is installed on the side wall of the connecting seat 31, and detects the water temperature in the hot water interface 316.

[0066] The hot water interface 316 is connected to the outlet of the heating body 4, and the temperature sensor 7 detects the water temperature in the hot water interface 316 in real time, that is, detects the temperature of the outlet of the heating body 4, which can accurately feedback temperature data, so as to facilitate the control system to adjust the heating power of the heating body 4, ensure that the water temperature accurately reaches the preset value of boiling, avoid boiling failure caused by too high or too low water temperature, improve the use safety, avoid energy waste, and the setting of the temperature sensor 7 makes the temperature control of boiling more accurate, further optimizing the boiling effect.

[0067] In a further preferred embodiment, the partition rib 315 extends into the cold water cavity 37 and is provided with a water inlet column 38 for connecting the water supply pipe 21, and the water inlet column 38 is provided with a hot water inlet channel 381 penetrating into the boiling cavity 33, and the two ports of the hot water inlet channel 381 are the hot water interface 316 and the hot water inlet 312. When the temperature sensor 7 is installed, the temperature sensing probe is inserted into the hot water inlet channel 381, ensuring accurate temperature measurement.

[0068] In a further preferred embodiment, the shell body 11 is further provided with an adapter seat 8, and the connecting seat 31 is rotatably connected to the adapter seat 8 to realize angle adjustment of the water outlet cantilever 12. The adapter seat 8 has a hot water adapter cavity 81 and a cold water adapter cavity 82 surrounding the hot water adapter cavity 81, and the hot water adapter cavity 81 is sealingly matched with the water inlet column 38, that is, the water supply pipe 21 is connected to the boiling cavity 33 through the hot water adapter cavity 81. The cold water pipe 6 includes a cold water supply pipe 61 longitudinally arranged in the shell body 11 and a cold water outlet pipe 62 arranged on the water outlet cantilever 12, and the cold water supply pipe 61 is connected to the cold water cavity 37 through the cold water adapter cavity 82.

[0069] In other preferred embodiments, referring to Figure 1 , Figure 2 and Figure 4The top surface of the water outlet cantilever 12 is provided with a mounting opening 122, and the top of the boiling bin 33 protrudes from the top surface of the water outlet cantilever 12 at the mounting opening 122. The top of the boiling bin 33 is transparent and visible.

[0070] In the embodiment, the top of the boiling bin 33 is transparent, specifically, the sealing cover 34 is made of transparent material, so that a user can directly observe the rolling boiling state of the hot water in the bin and clearly confirm whether boiling is normally occurring, thereby enhancing the trust of the user in the product. The design that the top of the boiling bin 33 protrudes from the top surface of the water outlet cantilever 12 expands the visible angle and makes observation more convenient.

[0071] In some alternative embodiments, with reference to Figures 1 to 3 The top of the boiling bin 33 is provided with an outer cover 9, and the top surface of the water outlet cantilever 12 is provided with a mounting opening 122. The outer cover 9 protrudes from the top surface of the water outlet cantilever 12 at the mounting opening 122. The top of the boiling bin 33 and the outer cover 9 are transparent and visible.

[0072] In the embodiment, the outer cover 9 is transparent and visible. Specifically, the outer cover 9 can be fixed to the top surface of the water outlet cantilever 12 by buckling, glue sealing or the like. The outer cover 9 not only plays a protective role and can effectively prevent dust and foreign matter from entering the boiling bin 33 to ensure stable boiling, but also does not block the line of sight for observation. At the same time, the outer cover 9 can effectively insulate heat, thereby ensuring the safety of the user.

[0073] In a further preferred embodiment, the thickness of at least one of the top of the sealing cover 34 and the top of the outer cover 9 gradually decreases from the center to the edge, that is, the thickness of the center is greater than the thickness of the periphery, so that the sealing cover 34 and the outer cover 9 form a convex mirror. The magnifying effect of the convex mirror can magnify the inside of the boiling bin 33, so that the observation effect is more obvious.
