[0002] With the improvement of people's living quality, there are higher requirements for the quality and convenience of water use. Water purifiers with the function of integrating purification and heating are more and more widely used in families and office places. At present, the purified water processed by the water purifier is usually divided into two paths for transportation. One path is to directly transport the normal-temperature purified water to the faucet, and the other path is to heat the water to hot water through a heater and then transport it to the faucet to meet the water use requirements of users at different temperatures.

[0003] Regarding the solution of mixing normal-temperature water and hot water (or boiling water) to provide warm water at an appropriate temperature, the conventional method is that the hot water outlet pipe and the normal-temperature water outlet pipe of the water purifier are independent of each other, and the water flows into the faucet separately and is simply mixed and then output. In this way, it is easy to have insufficient mixing of water, and there is a large temperature difference in each part, resulting in uneven cold and heat when the water is discharged (part of the water is cold and part of the water is hot at the same time when the water is discharged). For example, when consumers need to take warm water at 50-60°C, the local water temperature at the faucet may be as high as 80-90°C, which brings the risk of scalding to users and poses a safety hazard in the use of the water purifier.

[0037] In one embodiment, a water purifier faucet is proposed. Referring to Figures 1 to 4 , the water purifier faucet includes: a mixing cavity, a water outlet cavity, and two water pipe interfaces; wherein, the two water pipe interfaces are respectively connected to two inlets of the mixing cavity, and the two water pipe interfaces are respectively used for connecting to the normal temperature water pipe and the hot water pipe of the water purifier;

[0038] A circular cavity and a flow guiding structure are provided in the mixing cavity; the circular cavity is provided in front of the outlet of the mixing cavity, and the flow guiding structure is used to converge the water flows entering the mixing cavity and introduce them into the circular cavity to form a swirling water flow;

[0039] The water outlet cavity is connected to the outlet of the mixing cavity, and a bubbler is provided at the inlet of the water outlet cavity.

[0040] In this embodiment, there are a total of two water pipe interfaces of the water purifier faucet, which are respectively connected to two inlets of the mixing cavity. Their function is to serve as connection channels. One water pipe interface is used to connect to the normal temperature water pipe of the water purifier, and the other is used to connect to the hot water (or boiling water) pipe of the water purifier, responsible for introducing the normal temperature water and hot water into the faucet for subsequent processing.

[0041] The mixing cavity includes a circular cavity and a flow guiding structure; wherein, the flow guiding structure is located inside the mixing cavity and is the intermediate link connecting the two water pipe interfaces and the circular cavity. When the normal temperature water and hot water enter the mixing cavity through the two water pipe interfaces respectively, the flow guiding structure will guide them to avoid disordered collision or simple surface contact of the two water flows in the mixing cavity, but make them converge according to a predetermined path and manner. Through this orderly convergence, conditions are created for the formation of an effective swirling water flow in the circular cavity subsequently, enabling the two water flows to be better mixed.

[0042] A circular cavity is arranged in front of the outlet of the mixing cavity, which is a key area for the water flow in the mixing cavity to complete the final mixing. Its circular structure provides an annular movement path for the water flow, enabling the water flow to move in a circular motion around the center. When the guiding structure introduces the confluent water flow into the circular cavity, due to the circular restriction and the inertia of the water flow itself, a swirling water flow will be formed in the circular cavity. This swirling water flow has a powerful stirring effect, and the normal-temperature water and hot water are continuously tumbling, colliding and mixing under the drive of the swirl. During this process, the heat transfer between the hot water and cold water is more sufficient, and the two parts of water with a large original temperature difference can be mixed together more quickly and evenly, thus effectively reducing the temperature difference of each part of the water and avoiding the occurrence of uneven heating and cooling.

[0043] The outlet of the mixing cavity is connected to the water outlet cavity. After the water is fully mixed and flows out of the mixing cavity, it enters the water outlet cavity.

[0044] Among them, a bubbler is installed at the inlet of the water outlet cavity. The bubbler is a device with a porous structure. When the water flow passes through, it can disperse the water and mix in air to form a water flow with bubbles.

[0045] The working principle of the water purifier faucet is as follows:

[0046] When the user turns on the water purifier faucet to use water, the treated normal-temperature pure water and the heated hot water in the water purifier respectively pass through the corresponding normal-temperature water pipe and hot water pipe, and enter the mixing cavity through two water pipe interfaces. This is the starting stage of the entire water mixing process, ensuring that two kinds of water with different temperatures can smoothly enter the faucet for mixing.

[0047] After the normal-temperature water and hot water enter the mixing cavity, the guiding structure begins to play a role. It will guide the two water flows according to its own design, making them converge orderly. This orderly convergence avoids the disorderly collision and simple surface contact of the water flows, allowing the normal-temperature water and hot water to start contacting and exchanging heat more fully.

[0048] The confluent water flow enters the circular cavity under the guidance of the guiding structure. Due to the special structure of the circular cavity, the water flow will rotate around the center in it, forming a swirling water flow. Under the action of the swirl, the normal-temperature water and hot water are continuously tumbling, colliding and mixing. This violent movement greatly increases the contact area and contact time between the two kinds of water, enabling heat to be transferred more quickly and evenly between the hot water and cold water. After being processed by the circular cavity, the normal-temperature water and hot water with a large original temperature difference can be fully mixed, and the temperature difference of each part of the water is significantly reduced, thus effectively avoiding the situation of uneven heating and cooling.

[0049] The water that has been fully mixed in the mixing chamber flows into the water outlet chamber from the mixing chamber outlet. When entering the water outlet chamber, the water will first pass through the bubbler at the entrance. The porous structure of the bubbler divides the water into many tiny water droplets, and at the same time mixes air to form bubbles. On the one hand, this increases the surface area of ​​the water, so that the heat inside the water can be distributed more evenly; on the other hand, even if there are some slight temperature differences in the mixing chamber, the temperature of the water that finally flows out can be more uniform and stable after further blending by the bubbler. Finally, the optimized water flows out of the water outlet chamber for users to use. At this time, the water temperature is uniform, which reduces the risk of scalding users due to excessive local water temperature and ensures safety of use.

[0050] Moreover, the bubbler is cleverly placed at the entrance of the water outlet cavity connected to the outlet of the mixing cavity. This enables the bubbler to form a certain blocking effect on the mixed water flowing out of the mixing cavity. While effectively reducing the impact of the water flow, it also prolongs the residence time of the mixed water in the mixing cavity. In this way, the mixed water has more time to be fully mixed, thereby further improving the uniformity of water temperature and the mixing effect.

[0051] In addition, the bubbler can make the flowing water form more delicate and rich foam. Such water flow looks softer and has a larger flow rate, giving users a better visual and product experience.

[0052] In one embodiment, the water purifier faucet guides the room temperature water and hot water to merge through the guide structure in the mixing cavity, and forms a vortex water flow in the circular cavity. Combined with the joint action of the bubbler at the entrance of the water outlet cavity, the room temperature water and hot water can be fully mixed, avoiding the problem of uneven hot and cold water output from the water purifier, thereby providing users with water with uniform temperature, safety and appropriateness.

[0053] In one embodiment, based on the above embodiment, referring to Figure 3 and Figure 4 , the circular cavity is wrapped by the guide structure; the C-shaped outer wall opening of the circular cavity serves as the inlet of the circular cavity;

[0054] The guide structure is symmetrically provided with blocking members and guide members arranged in conjunction with the blocking members at the two entrances of the mixing chamber; wherein the blocking members are used to reduce the impact force of the water flow; and the guide members are used to guide the water flow to the C-shaped outer wall so that the water flow flows along the C-shaped outer wall to the guide entrance.

[0055] In this embodiment, the circular cavity is wrapped by a diversion structure. This design not only makes the mixing cavity structure compact, saves the faucet structure space and material costs (making the faucet particularly suitable for small and medium-sized water purifiers), but also the diversion structure can guide and control the water flow entering the mixing cavity to ensure that the water flow can accurately enter the circular cavity. The opening of the C-shaped outer wall of the circular cavity serves as the inlet. This special structural design provides a specific channel for the water flow to enter the circular cavity, which helps to form a specific water flow movement pattern.

[0056] Blocking members are symmetrically arranged at the two inlets of the mixing cavity in the diversion structure. This means that at the positions where the normal temperature water and the hot water enter the mixing cavity respectively, there are blocking members for corresponding treatment. The specific form of the blocking member can be a baffle, a protrusion, etc. Its main function is to change the flow direction and speed of the water flow.

[0057] When the normal temperature water and the hot water flow into the mixing cavity at high speed from their respective water pipe interfaces, the water flow has a certain impact force (especially for a water purifier with a small outlet pipe diameter, its water outlet flow rate is generally very large). The existence of the blocking member can reduce this impact force and prevent the water flow from entering the mixing cavity in too violent a manner, resulting in chaotic water flow, which is not conducive to the subsequent mixing process. By reducing the impact force, the water flow enters the mixing cavity more smoothly, creating good conditions for subsequent diversion and mixing.

[0058] The diversion member is arranged in cooperation with the blocking member and is also located at the two inlets of the mixing cavity. The diversion member can be in the shape of an arc (as shown in Figure 5 ), an inclined plate, etc. Its design purpose is to guide the direction of the water flow. After the blocking member reduces the impact force of the water flow, the diversion member begins to play a role. The diversion member can direct the water flow to the C-shaped outer wall of the circular cavity, making the water flow flow along the C-shaped outer wall and finally smoothly flow to the inlet. This guiding method enables the water flow to enter the circular cavity in an orderly manner, providing the necessary conditions for forming a swirling water flow. By flowing along the C-shaped outer wall, the water flow already has a certain tendency of circular motion (that is, the water flow has flowed along an arc for a certain distance) before entering the circular cavity. When it enters the circular cavity, it is easier to form a stable swirling water flow, thus promoting the full mixing of the normal temperature water and the hot water.

[0059] When the normal temperature water and the hot water enter the mixing cavity through the two water pipe interfaces respectively, they first encounter the blocking member. The blocking member reduces the impact force of the water flow and makes the water flow more stable. Then, the diversion member directs the stable water flow to the C-shaped outer wall of the circular cavity. The water flow flows along the C-shaped outer wall and flows to the inlet. At the inlet, the two water flows start to intersect and merge initially, and under the action of inertia and pressure, they enter the circular cavity together.

[0060] Inside the circular cavity, due to its circular structure and the inertia of the water flow, a swirling water flow is formed. Under the action of the swirling water flow, the normal temperature water and the hot water continuously tumble, collide and blend, achieving sufficient mixing.

[0061] In this way, through the synergistic effect of the blocking member and the guiding member, the water flow can enter the circular cavity in an orderly and stable manner, forming a stable swirling water flow, greatly improving the mixing effect of the normal temperature water and the hot water, and reducing the phenomenon of uneven heating and cooling. The design of wrapping the circular cavity with the guiding structure makes the structure of the entire mixing cavity more compact, the space utilization more efficient, and is conducive to the miniaturization design of the water purifier faucet. This structural design reduces the disorderly movement and impact of the water flow, reduces the risk of component damage, and improves the reliability and service life of the water purifier faucet.

[0062] In one embodiment, on the basis of the above embodiment, referring to Figure 2 , a temperature sensor is further provided in the mixing cavity, and the data terminal of the temperature sensor is used to connect to the temperature control module of the water purifier and feedback the water temperature data.

[0063] In this embodiment, the temperature sensor is installed in the mixing cavity and can directly contact the water flow in the mixing cavity, so as to accurately measure the real-time water temperature after the normal temperature water and the hot water are mixed. Its data terminal is connected to the temperature control module of the water purifier, and this connection method builds a channel for the transmission of temperature data, enabling the water temperature data collected by the temperature sensor to be timely and accurately fed back to the temperature control module.

[0064] The temperature sensor continuously monitors the temperature of the mixed water in the mixing cavity. When the normal temperature water and the hot water are mixed in the mixing cavity, the temperature sensor can quickly sense the change in the water temperature and convert it into a data form such as an electrical signal that can be transmitted.

[0065] The temperature sensor feeds back the collected water temperature data to the temperature control module of the water purifier. The temperature control module is the core of the water purifier temperature control. After receiving the water temperature data, it will compare and analyze it with the pre-set target water temperature.

[0066] If the actual water temperature is lower than the target water temperature: the temperature control module will issue an instruction to increase the water flow rate of the hot water pipe or increase the heating power of the hot water, so as to raise the temperature of the mixed water and make it close to the target water temperature.

[0067] If the actual water temperature is higher than the target water temperature: the temperature control module will correspondingly increase the water flow rate of the normal temperature water pipe or adjust the supply of hot water, thereby reducing the temperature of the mixed water and ensuring that the finally flowing out water temperature meets the user's requirements.

[0068] The combination of temperature sensors and temperature control modules enables the water purifier to accurately adjust the temperature according to the real-time water temperature, providing users with water with stable temperature and in line with their needs. Whether it is the appropriate hot water temperature for making tea or the mixed temperature of room temperature and hot water for daily drinking, it can be achieved through this precise control.

[0069] In this way, users do not need to manually adjust the water temperature or try multiple times to get water at the right temperature. The water purifier can automatically adjust according to the feedback data, greatly improving the convenience and comfort of use. By real-time monitoring and precise adjustment of water temperature, overheating or cooling is avoided, energy waste is reduced, and the energy efficiency of the water purifier is improved.

[0070] In one embodiment, based on the above embodiment, referring to Figure 5 The mixing cavity is provided with a detachable locking cover, in which a mounting position for the temperature sensor is provided; when the locking cover locks the mixing cavity, the detection end of the temperature sensor placed at the mounting position is inserted into the circular cavity, and the data end of the temperature sensor is located outside the mixing cavity.

[0071] In this embodiment, the detachable locking cover is a cover structure that can be connected to and separated from the mixing chamber. Although the locking cover is detachable, it can be firmly locked when installed on the mixing chamber. This locking can ensure a tight connection between the cover and the chamber, prevent water leakage, or prevent foreign matter from entering the chamber.

[0072] Optionally, the connection between the locking cover and the mixing chamber can be a snap connection, a threaded connection, a magnetic connection, etc. Preferably, the snap connection is used, and the snap connection is used as an example for explanation below: a snap is provided on the edge of the cover, and a corresponding slot is provided at the opening of the chamber. When installing, after aligning the cover with the chamber, rotate the cover so that the snap is snapped into the slot to achieve locking; when disassembling, the cover can be removed by rotating the cover in the opposite direction to move the snap so that it is disengaged from the slot.

[0073] The installation position of the temperature sensor is set in the locking cover to achieve the rational use of space and optimization of layout. The temperature sensor is an important component for monitoring the water temperature in the mixing chamber. If it is directly installed in the mixing chamber, it may occupy the internal space of the mixing chamber and affect the mixing effect and flow path of the water flow. Setting the installation position on the locking cover can ensure that the detection end of the temperature sensor can be inserted into the mixing chamber to accurately measure the water temperature, and will not interfere with the structure and water flow inside the mixing chamber, making the structure of the entire water purifier faucet more compact and reasonable.

[0074] An installation position for a temperature sensor is provided in the locking cover. Installing the temperature sensor on the installation position on the locking cover facilitates the installation and replacement operations of the temperature sensor. During installation, simply place the temperature sensor on the installation position and ensure that the detection end is inserted into the circular cavity to complete the installation. The operation is simple and fast. When the temperature sensor fails or needs to be calibrated or replaced, there is no need to perform complex disassembly on the mixing cavity. Just open the locking cover to easily operate the temperature sensor, improving the maintenance efficiency and convenience.

[0075] When the locking cover locks the mixing cavity, the detection end of the temperature sensor is inserted into the circular cavity and can directly contact the mixed water flow, thereby accurately measuring the temperature of the mixed water. The direct contact of the detection end can avoid measurement errors caused by the influence of intermediate media or environmental factors, ensuring the accuracy and reliability of temperature measurement. This is of great significance for application scenarios that require precise control of water temperature, such as making milk powder or brewing tea, and can provide users with more accurate water temperature information.

[0076] The data end of the temperature sensor is located outside the mixing cavity, facilitating connection with external control circuits or display devices. The data end can transmit the measured temperature data to the control module of the water purifier through wires or other means to achieve real-time monitoring and control of the water temperature. At the same time, the temperature data can also be transmitted to the display device for users to intuitively understand the temperature of the mixed water. This position setting avoids complex data transmission line layout inside the mixing cavity, reduces the possibility of line failures and interference, and improves the stability and reliability of data transmission.

[0077] In one embodiment, based on the above embodiment, refer to Figure 6 , the water purifier faucet is of an L-shaped structure; wherein, the angle between the direction in which the water pipe interface is connected to the mixing cavity and the direction in which the water outlet cavity is connected to the mixing cavity is 90°.

[0078] In this embodiment, the water purifier faucet adopts a unique L-shaped structure design. Among them, a 90° angle is formed between the direction in which the water pipe interface is connected to the mixing cavity and the direction in which the water outlet cavity is connected to the mixing cavity.

[0079] From the perspective of spatial layout, the L-shaped structure makes the faucet have a certain bend in the overall shape. The two water pipe interfaces are connected to the mixing cavity in a relatively horizontal (or nearly horizontal) manner, while the water outlet cavity is connected to the mixing cavity in a direction perpendicular (or nearly perpendicular) to the connection direction of the water pipe interfaces. Such a layout makes the faucet more compact in appearance and can better adapt to different installation environments.

[0080] Since the connection direction between the water pipe interface and the water outlet cavity forms a 90° angle, when normal temperature pure water and hot water flow into the mixing cavity from the water pipe interface, the water flow direction will change significantly. This makes the collision between the two water flows at different temperatures more intense in the mixing cavity, increasing their contact area and mixing opportunities. Compared with the traditional linear or small-angle connection method, the L-shaped structure enables the normal temperature water and hot water to form a more complex flow path in the mixing cavity, thereby promoting more sufficient heat exchange, further improving the mixing effect, and reducing the water temperature difference.

[0081] This structure makes the flow of water in the mixing cavity no longer a simple linear flow but requires a change in direction. During the process of changing direction, the speed of the water flow will slow down to some extent, thus prolonging the residence time of the mixed water in the mixing cavity. Just like the function of the bubbler mentioned before, a longer residence time means that the mixed water has more time for sufficient mixing, which helps to form water with a uniform temperature at the outlet.

[0082] The 90° angle design also helps to improve the stability of the water outlet to a certain extent. When the mixed water changes direction and flows into the water outlet cavity after passing through the mixing cavity, the impact force of the water flow will be buffered and adjusted during this process, making the water finally flowing out of the water outlet cavity more stable, reducing the situation of water splashing, and enhancing the user experience.

[0083] Optionally, in order to make the water purifier faucet more suitable for small and medium-sized household devices such as water purifiers with a compact space layout, with the direction of the water pipe interface connecting to the mixing cavity as the length direction, the direction of the water outlet cavity connecting to the mixing cavity as the height direction, and the direction perpendicular to both the length and height as the width direction, it is recommended that the size of the water purifier faucet be 45 - 50 mm in length, 35 - 40 mm in height, and 35 - 40 mm in width, and the diameter of the water pipe connected to the water pipe interface be within 10 mm.

[0084] In one embodiment, on the basis of the above embodiment, referring to Figure 2 , the water outlet side of the bubbler is arranged at the outlet of the water outlet cavity;

[0085] and / or, the water inlet side of the bubbler is a conical convex surface.

[0086] In this embodiment, the water outlet side of the bubbler is arranged at the outlet of the water outlet cavity. This design aims to further optimize the water outlet effect of the water purifier faucet. And setting the water outlet side of the bubbler at the outlet of the water outlet cavity enables the water outlet cavity to just accommodate the bubbler, which can save structural space and material costs.

[0087] Optionally, the water inlet side of the bubbler is designed as a conical convex surface, mainly based on the principle of fluid mechanics. This special shape can guide and adjust the water flow entering the bubbler.

[0088] When the mixed water flows from the mixing cavity into the bubbler, the conical convex surface can evenly disperse the water flow. Compared with the flat water inlet side, the conical convex surface can prevent the water flow from concentrating at a certain point and entering the bubbler, so that the water flow passes through the filter screen or other structures inside the bubbler more evenly, improving the bubbling effect and mixing uniformity.

[0089] Under the guidance of the conical convex surface, the water flow will form a more complex flow path, increasing the contact and mixing opportunities between waters of different temperatures and different components. This helps to further improve the uniformity of water temperature and the mixing effect of water quality, making the temperature of the finally discharged water more stable and the composition more uniform.

[0090] In one embodiment, on the basis of the above embodiment, the bubbler is threadedly connected to the water outlet cavity; wherein, an external thread is provided on the side wall of the bubbler; and an internal thread is provided on the inner wall of the water outlet cavity.

[0091] In this embodiment, the connection between the bubbler and the water outlet cavity adopts a threaded connection. When assembling the water purifier faucet, only need to align the side wall of the bubbler with the external thread to the inner wall of the water outlet cavity with the internal thread at the outlet of the water outlet cavity, and then rotate it according to the rotation direction of the thread, and the bubbler can be easily installed on the water outlet cavity. This installation method does not require complex tools and operation skills, and even ordinary users can complete it by themselves.

[0092] When it is necessary to clean, replace or maintain the bubbler, the bubbler can also be disassembled from the water outlet cavity by rotating it in the reverse direction.

[0093] The threaded connection has good self-locking performance, which can ensure the stability of the connection between the bubbler and the water outlet cavity. Under the continuous impact of the water flow and the pressure change, the friction between the threads can effectively prevent the bubbler from loosening or falling off. When the water flows out from the mixing cavity through the bubbler and the water outlet cavity, certain water flow impact force and pressure fluctuation will be generated. If other connection methods are adopted, such as simple snap connection or socket connection, loosening or even falling off may occur under the long-term water flow impact, resulting in problems such as water leakage. The tightness and stability of the threaded connection can ensure that the bubbler is firmly fixed on the water outlet cavity under various working conditions, ensuring the normal use and safety of the faucet.

[0094] Threaded connections can also provide good sealing performance. When the external threads of the bubbler tightly fit with the internal threads of the water outlet cavity, the gaps between the threads can form a certain sealing effect through the screwing action of the threads, reducing the possibility of water leakage from the connection part. To further improve the sealing performance, sealing materials such as PTFE tape can be wound around the threads to enhance the sealing effect, ensuring that water can only flow out of the bubbler along the designed path, improving the usage efficiency and reliability of the faucet.

[0095] In one embodiment, based on the above embodiment, a water pipe socket is built into the water pipe interface.

[0096] In this embodiment, building a water pipe socket into the water pipe interface can significantly improve the sealing performance between the water pipe and the interface. When the water pipe is inserted into the interface, the socket can closely fit the outer wall of the water pipe, filling the gap between the water pipe and the interface to prevent water leakage at the connection part.

[0097] The water pipe socket can play a role in protecting the water pipe. During the process of inserting the water pipe into the interface, the socket can reduce the friction between the water pipe and the edge of the interface, preventing the surface of the water pipe from being scratched or worn. Especially for some water pipes with relatively soft materials, such as plastic water pipes, this protective effect is more obvious.

[0098] The built-in water pipe socket can enhance the connection stability between the water pipe and the interface. It can provide additional friction force to fix the water pipe more firmly in the interface, preventing the water pipe from loosening or falling off under the action of water flow. Especially in the thin water pipes of water purifiers with relatively high water pressure, this stability is particularly important. If the water pipe connection is unstable, it may cause the water pipe to suddenly fall off, triggering safety accidents such as water disasters. The use of the water pipe socket can greatly improve the connection reliability and ensure the safe operation of the water circuit system.

[0099] In one embodiment, based on the above embodiment, a leak-proof gasket is provided between the water pipe socket and the inlet of the mixing cavity.

[0100] In this embodiment, setting a leak-proof gasket between the water pipe socket and the inlet of the mixing cavity can further enhance the sealing performance of this connection part. Although the water pipe socket itself can achieve sealing to a certain extent, with the increase of usage time and the influence of factors such as water flow impact and pressure change, fine gaps may appear at the connection, resulting in water leakage. The leak-proof gasket can fill these possible gaps, preventing water from seeping out from the connection part, ensuring that all water can flow into the mixing cavity for subsequent mixing treatment, avoiding waste of water resources and damage to the surrounding environment and equipment caused by water leakage.

[0101] When water flow enters the mixing cavity through a water pipe, it will generate a certain impact force and vibration. The leak-proof ring plug has a certain elasticity and can play a role in buffering and shock absorption. It can absorb the energy generated by the water flow impact, reduce the influence of vibration on the water pipe socket, the inlet of the mixing cavity and the entire connection structure, reduce the risk of component loosening and damage caused by vibration, and extend the service life of related components.

[0102] In addition, in the embodiments of the present application, a water purifier is also proposed. The water purifier includes a water purifier faucet, and the specific structure of the water purifier faucet refers to the above embodiments. Since this water purifier adopts all the technical solutions of the above all embodiments, it at least has all the technical effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0103] Among them, the hot water pipe outlet and the normal temperature water pipe outlet of the water purifier are respectively connected to two water pipe interfaces of the water purifier faucet.

[0104] In addition, in the embodiments of the present application, a control method for a water purifier is also provided. The water purifier is the water purifier described in the above embodiments; referring to Figure 7 , the control method of the water purifier includes:

[0105] Step S10: When receiving a warm water outlet instruction, control the water purifier to deliver normal temperature water and hot water to the faucet through the normal temperature water pipe and the hot water pipe respectively, so as to mix and output the normal temperature water and the hot water through the faucet;

[0106] Step S20: Based on the temperature sensor, monitor the mixed water temperature in the circular cavity of the mixing cavity of the faucet;

[0107] Step S30: If it is monitored that the mixed water temperature does not meet the preset condition, adjust the water outlet parameters of the water purifier until the mixed water temperature meets the target temperature; if it is monitored that the mixed water temperature has met the preset condition, keep the current water outlet parameters of the water purifier.

[0108] In this embodiment, when the user issues a warm water outlet instruction to the water purifier, the control system of the water purifier will immediately receive this instruction. This instruction can be issued in various ways, such as pressing the corresponding button on the operation panel of the water purifier, sending an instruction through the mobile phone APP, etc.

[0109] After receiving the instruction, the water purifier will control the normal temperature water pipe and the hot water pipe to deliver normal temperature water and hot water to the faucet respectively. The normal temperature water pipe draws water from the normal temperature water source of the water purifier, while the hot water pipe draws water from the hot water source that has been heated to the preset heating temperature. During the delivery process, the water flows through their respective pipes to the mixing cavity of the faucet, and through the diversion structure in the mixing cavity, the two water flows converge and are introduced into the circular cavity. Due to the circular structure and the inertia of the water flow, the normal temperature water and the hot water will form a swirling water flow. Under the action of the swirling water flow, the normal temperature water and the hot water continuously tumble, collide and blend, greatly increasing the contact area and mixing time between the two, thus achieving full mixing and effectively avoiding the phenomenon of uneven hot and cold.

[0110] At the same time, the temperature sensor of the water purifier starts to function, and will continuously sense the water temperature after the normal temperature water and the hot water are mixed in the circular cavity, and convert the water temperature information into data forms such as electrical signals. The data terminal of the temperature sensor transmits the collected water temperature data to the temperature control module of the water purifier. The temperature control module continuously monitors and analyzes these data in order to timely understand the change of the mixed water temperature.

[0111] The temperature control module compares the monitored mixed water temperature with the preset conditions. Among them, the preset conditions can be flexibly set according to different requirements. It is not limited to a single target temperature, but can also include temperature ranges, temperature fluctuation frequencies, etc. For example, the preset conditions can be set that the mixed water temperature is within the range of the target temperature ±1°C, and the temperature fluctuation does not exceed 0.5°C within a period of time. Such a setting can more comprehensively measure the temperature state of the mixed water, ensuring that the output warm water temperature meets the requirements and is stable.

[0112] Optionally, the temperature control module carefully compares the monitored mixed water temperature with the preset conditions. If the mixed water temperature is not within the preset temperature range, or the temperature fluctuation exceeds the allowed frequency, it means that the mixed water temperature does not meet the preset conditions.

[0113] Optionally, if the mixed water temperature is lower than the lower limit of the preset range, increase the water flow of the hot water pipe, and at the same time may appropriately reduce the water flow of the normal temperature water pipe to increase the overall temperature of the mixed water; if the mixed water temperature is higher than the upper limit of the preset range, increase the water flow of the normal temperature water pipe and correspondingly reduce the water flow of the hot water pipe to lower the temperature of the mixed water. The adjustment method is usually achieved by controlling the opening of the solenoid valve of the water pipe, for example, increasing or decreasing the opening of the solenoid valve to change the water flow.

[0114] Optionally, if it is detected that the temperature fluctuation frequency of the mixed water exceeds the preset value, it means that the mixing effect is not good, and there may be a situation of uneven hot and cold. At this time, the temperature control module can enhance the intensity of the swirling water flow in the circular cavity by adjusting the flow ratio of the normal temperature water and the hot water, changing the water flow speed, etc., to promote the full mixing of the water and reduce the temperature fluctuation.

[0115] After adjusting the water outlet parameters, the temperature sensor continuously monitors the temperature of the mixed water, and the temperature control module continuously compares the temperature of the mixed water with the preset conditions. If the temperature of the mixed water still does not meet the preset conditions, the above adjustment operations will continue until the temperature of the mixed water meets the preset conditions.

[0116] When the temperature control module monitors that the temperature of the mixed water has met the preset conditions, it will control the water purifier to maintain the current water outlet parameters. This means maintaining the current water flow rates of the normal temperature water pipe and the hot water pipe, as well as parameters such as the heating power of the hot water unchanged, to ensure that the temperature of the warm water output subsequently can be stably maintained within the preset condition range, providing a stable and uniform warm water supply for users.

[0117] In this way, while using the faucet structure with a unique structure to ensure the mixing effect of warm water and avoid uneven hot and cold, through real-time monitoring and precise adjustment, overheating or overcooling is avoided, energy waste is reduced, the energy utilization efficiency of the water purifier is improved, the warm water demand of users is met, and the user experience of using the water purifier is enhanced. At the same time, the optimized mixing process also helps to improve the effective utilization rate of energy, making the operation of the water purifier more economical and environmentally friendly.

[0118] In one embodiment, based on the above embodiment, the water outlet parameters include at least one of the following:

[0119] The water flow rate of the normal temperature water pipe and / or the hot water pipe;

[0120] The water flow velocity of the normal temperature water pipe and / or the hot water pipe;

[0121] The heating temperature of the hot water.

[0122] In this embodiment, the functions and adjustment methods of different water outlet parameters in adjusting the temperature of the mixed water are as follows:

[0123] (1) The water flow rate of the normal temperature water pipe and / or the hot water pipe

[0124] The water flow rates of the normal temperature water and the hot water directly affect the temperature of the mixed water. Increasing the water flow rate of the hot water pipe will increase the proportion of hot water in the mixed water, thereby increasing the temperature of the mixed water; conversely, increasing the water flow rate of the normal temperature water pipe will increase the proportion of cold water in the mixed water, reducing the temperature of the mixed water.

[0125] Optionally, the water flow rate is adjusted by controlling the opening degrees of the solenoid valves installed on the normal-temperature water pipe and the hot-water pipe. When the temperature control module determines that the mixed water temperature does not meet the preset conditions, if it is necessary to increase the temperature, the opening degree of the solenoid valve on the hot-water pipe can be increased, and / or the opening degree of the solenoid valve on the normal-temperature water pipe can be decreased; if it is necessary to decrease the temperature, the opening degree of the solenoid valve on the normal-temperature water pipe is increased, and / or the opening degree of the solenoid valve on the hot-water pipe is decreased. For example, when the preset temperature requirement is relatively high and the current mixed water temperature is relatively low, the temperature control module will gradually increase the opening degree of the solenoid valve on the hot-water pipe to allow more hot water to flow into the mixing cavity, causing the mixed water temperature to rise.

[0126] (2) Water flow rate of the normal-temperature water pipe and / or the hot-water pipe

[0127] The water flow rate affects the mixing effect and mixing time of water in the mixing cavity. A higher water flow rate can enhance the degree of water turbulence, enabling the normal-temperature water and hot water to mix faster and more fully, which helps improve the mixing uniformity and thus more accurately reach the preset temperature. At the same time, changing the water flow rate will also indirectly affect the temperature of the mixed water. For example, increasing the water flow rate in the hot-water pipe is equivalent to increasing the supply of hot water per unit time, which may cause the temperature of the mixed water to rise.

[0128] Optionally, the water flow rate can be changed by adjusting the power of the water pump. If it is necessary to increase the water flow rate, the temperature control module will increase the power of the water pump; if it is necessary to decrease the water flow rate, the power of the water pump is decreased. For instance, when it is detected that the mixed water temperature fluctuates greatly, indicating poor mixing effect, the temperature control module can appropriately increase the water flow rates of the normal-temperature water and the hot water to enhance the intensity of the swirling water flow in the mixing cavity and promote the full mixing of water.

[0129] (3) Heating temperature of the hot water

[0130] The heating temperature of the hot water directly determines the initial temperature of the hot water entering the mixing cavity. Increasing the heating temperature of the hot water can enable the mixed water to reach a relatively high temperature faster when mixed with the normal-temperature water; decreasing the heating temperature of the hot water will reduce the rising amplitude of the mixed water temperature.

[0131] Optionally, the heating temperature of the hot water is adjusted by controlling the power of the heating element (such as a heating pipe). When the mixed water temperature is lower than the preset conditions and simply adjusting the water flow rate and flow velocity has little effect, the temperature control module will increase the power of the heating element to raise the heating temperature of the hot water; when the mixed water temperature is too high, the power of the heating element is decreased to lower the heating temperature of the hot water. For example, in a relatively low ambient temperature in winter, it may be necessary to increase the heating temperature of the hot water to ensure that the mixed water can reach the preset temperature.

[0132] Optionally, by comprehensively adjusting multiple water outlet parameters such as water flow rate, water flow speed, and hot water heating temperature, the mixing temperature can be precisely adjusted from different perspectives. For example, when only adjusting the water flow rate cannot quickly meet the preset conditions for the mixing temperature, combining the adjustment of the water flow speed and the hot water heating temperature can more effectively achieve precise temperature control.

[0133] Optionally, considering that there are significant differences in different ambient temperatures and user demands for warm water. For example, in summer and winter, the ambient temperatures are different, and the initial water temperatures are also different. Comprehensively adjusting the water outlet parameters can better adapt to these changes. At the same time, different usage scenarios (such as making tea, brewing coffee, making milk powder, etc.) have different requirements for the temperature of warm water. By flexibly adjusting multiple water outlet parameters, diverse demands can be met.

[0134] Optionally, the adjustment of the water flow speed helps to enhance the mixing effect of water, enabling the cold water and hot water to fully blend and reducing the phenomenon of uneven hot and cold. The reasonable adjustment of the water flow rate and the hot water heating temperature can ensure that the temperature of the mixed water is stable within the preset condition range, providing users with a stable and uniform warm water output.

[0135] In one implementation, based on the above embodiments, when the mixing temperature fluctuates greatly and the mixing effect is poor within a certain period of time, the adjustment can start from the water flow speed of the cold water pipe and / or the hot water pipe. The following are the specific adjustment methods:

[0136] Optionally, increase the water flow speeds of both the cold water pipe and the hot water pipe simultaneously. A higher flow speed will enhance the turbulence degree of the water, enabling the cold water and hot water to interpenetrate and blend more fully. The increase in flow speed can be achieved by increasing the pump power. For example, increasing the original water flow speed of 1 m / s to 1.5 m / s, allowing the water to flow rapidly in the mixing cavity, increasing the contact area and mixing opportunities between them.

[0137] Optionally, make the water flow speeds of the cold water pipe and the hot water pipe form a certain gradient. For example, make the water flow speed of the hot water pipe 0.5 m / s faster than that of the cold water pipe. This flow speed difference will generate a shear force during the mixing process, further promoting the mixing of water. Moreover, the flow speed gradient can be dynamically adjusted according to the actual mixing effect until the fluctuation of the mixing temperature decreases.

[0138] In summary, for the water purifier faucet, water purifier, and control method provided in the embodiments of the present application, the water purifier faucet guides the cold water and hot water to converge through the diversion structure in the mixing cavity, forms a swirling water flow in the circular cavity, and together with the bubbler at the entrance of the water outlet cavity, can fully mix the cold water and hot water, avoiding the problem of uneven hot and cold in the water purifier outlet, thereby providing users with water with uniform temperature, safety, and suitability.
