Description

[0002] With the improvement of people's life quality, the quality and convenience of water have higher requirements, and the water purifier with the integrated function of purifying and heating is more and more widely used in families and offices. At present, the pure water treated by the water purifier is usually delivered in two ways, one way is that the normal temperature pure water is directly delivered to the faucet, and the other way is that the normal temperature pure water is heated into hot water (or boiling water) by the heater and then delivered to the faucet to meet the water demand of users with different temperatures.

[0003] However, for the scheme of mixing normal temperature water and hot water to provide warm water with appropriate temperature, the conventional way 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 respectively and is simply mixed and then output. In this way, the water mixing is not sufficient, the temperature difference of each part of the water is large, and the water output is prone to uneven cold and hot (part of the water is cold and part of the water is hot at the same time). For example, when the consumer needs to take 50-60 DEG C warm water, the local water temperature of the faucet port may be as high as 80-90 DEG C, which brings the risk of scalding to the user and causes safety hazards in the use of the water purifier.

Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the present application.

[0025] The present application provides a water purifier faucet, referring to Figure 1 and Figure 2 The water purifier faucet comprises 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 a normal temperature water pipe and a hot water pipe of the water purifier; the water outlet cavity is connected to an outlet of the mixing cavity, and a bubbler is arranged at an inlet of the water outlet cavity; a temperature sensor is arranged in the mixing cavity, and a data end of the temperature sensor is used for connecting a temperature control module of the water purifier.

[0026] In this embodiment, the water purifier faucet has two water pipe interfaces. These two interfaces are connected to two different inlets of the mixing chamber. The purpose of this dual-interface design is to introduce the normal-temperature pure water produced by the water purifier and the heated hot water (or boiling water) separately, just like two "channel gates", accurately guiding the water from different sources (normal-temperature water pipe and hot water pipe) into the mixing chamber, providing the basis for subsequent water temperature mixing.

[0027] The mixing chamber is one of the core components of the faucet, which is located between the two water pipe interfaces and the water outlet chamber. Its shape is a relatively closed chamber with enough space to accommodate normal-temperature water and hot water flowing in from the two water pipe interfaces.

[0028] When normal-temperature pure water and hot water flow into the mixing chamber through the two water pipe interfaces respectively, as the water flow enters from different directions, they will collide and intersect with each other in the chamber. This collision and intersection allows the two different temperature waters to fully contact and heat begins to transfer between them. As the water flow continues to flow and mix in the mixing chamber, the temperature of each part gradually tends to be consistent, thereby reducing the water temperature difference and reducing the possibility of uneven water temperature.

[0029] Among them, the mixing chamber can also be provided with corresponding flow guide structure to guide the normal-temperature water and hot water to fully mix and be guided to the water outlet chamber.

[0030] A temperature sensor is arranged inside the mixing chamber, and its data end is connected to the temperature control module of the water purifier, which will continuously transmit the detected temperature data to the temperature control module, providing the basis for subsequent temperature adjustment.

[0031] The water outlet chamber is connected at the outlet of the mixing chamber, which is the last stop for the mixed water to flow out of the faucet. Its role is to guide the fully mixed water to the outside of the faucet for user use.

[0032] A bubbler is installed at the inlet of the water outlet chamber. When the mixed water flows through the bubbler, it will disperse the water flow into many small water bubbles. This process not only further optimizes the mixing effect of the water, making the water temperature that has not been completely uniform in the mixing chamber more consistent, but also makes the touch of the water more soft and delicate. At the same time, the bubbler can also reduce the impact force of the water flow to some extent, making the water flow out of the faucet more stable.

[0033] Moreover, the bubbler is cleverly placed at the inlet of the water outlet chamber connected to the outlet of the mixing chamber. This allows the bubbler to form a certain blocking effect on the mixed water flowing out of the mixing chamber. While effectively reducing the impact force of the water flow, it also prolongs the residence time of the mixed water in the mixing chamber. In this way, the mixed water has more time to fully mix, thereby further improving the uniformity of the water temperature and the mixing effect.

[0034] In addition, the bubbler can make the water flow form more delicate and rich foam, and such water flow looks more soft and large in flow, and brings better visual and product use experience to the user.

[0035] The temperature control module, although not a physical component of the faucet itself, works closely with the faucet by connecting with the data end of the temperature sensor in the mixing cavity. The temperature control module receives real-time water temperature data from the temperature sensor and compares it with the pre-set target water temperature.

[0036] Optionally, if the detected water temperature is higher than the target water temperature, the temperature control module will issue an instruction to appropriately increase the water flow of the normal temperature water pipe and reduce the water flow of the hot water pipe; on the contrary, if the detected water temperature is lower than the target water temperature, the temperature control module will increase the water flow of the hot water pipe and reduce the water flow of the normal temperature water pipe. Through this intelligent adjustment mode, the temperature control module can accurately control the temperature of the mixed water to ensure that the user finally receives water at a suitable temperature, avoiding the safety hazard of scalding caused by local water temperature being too high.

[0037] In this way, when the user needs to use water at a suitable temperature, the normal temperature pure water and hot water of the water purifier flow into the mixing cavity through the two water pipe interfaces respectively. In the mixing cavity, the two kinds of water are mixed with each other, the temperature sensor monitors the water temperature in real time and transmits the data to the temperature control module. The water that has been fully mixed then flows into the water outlet cavity and further optimizes the mixing effect when passing through the bubbler, and finally flows out of the faucet at a temperature that is uniform, good in taste, safe and suitable, meeting the user's water demand.

[0038] In an embodiment, the water purifier faucet effectively solves the problem of insufficient mixing of normal temperature water and hot water and uneven cold and hot through the cooperative work of the mixing cavity, the bubbler and the temperature sensor and the temperature control module, thereby providing the user with water at a uniform temperature, which is safe and suitable.

[0039] In an embodiment, on the basis of the above-mentioned embodiment, with reference to Figure 3 , the water purifier faucet is of an L-shaped structure; wherein the included angle between the direction in which the water pipe interface connects the mixing cavity and the direction in which the water outlet cavity connects the mixing cavity is 90°.

[0040] In this embodiment, the water purifier faucet adopts a unique L-shaped structure design, in which the included angle between the direction in which the water pipe interface connects the mixing cavity and the direction in which the water outlet cavity connects the mixing cavity is 90°.

[0041] From the spatial layout, the L-shaped structure makes the faucet have a certain bending in the overall modeling. The two water pipe interfaces access the mixing cavity in a relatively horizontal (or close to horizontal) manner, while the water outlet cavity is connected with the mixing cavity in a vertical (or close to vertical) manner to the access direction of the water pipe interface. Such a layout makes the faucet more compact in appearance and better adapts to different installation environments.

[0042] Since the connection direction of the water pipe interface and the water outlet cavity forms a 90° angle, when the 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 of water flows of two different temperatures in the mixing cavity more intense, increasing the contact area and mixing opportunity between them. Compared with the traditional straight line type or small angle connection method, the L-shaped structure can make the normal temperature water and hot water 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.

[0043] This structure makes the water flow in the mixing cavity no longer a simple straight flow, but needs to change direction. In the process of changing direction, the speed of the water flow will slow down, thereby prolonging the residence time of the mixed water in the mixing cavity. As mentioned earlier, the role of the bubbler is the same, longer residence time means that the mixed water has more time to mix thoroughly, which helps to form water with uniform temperature.

[0044] The 90° angle design also helps to improve the stability of the water to some extent. When the mixed water changes direction after passing through the mixing cavity and flows into the water outlet cavity, the impact force of the water flow will be buffered and adjusted to some extent in this process, so that the water finally flowing out of the water outlet cavity is more stable, reducing the splashing of water, and improving the user's experience.

[0045] Optionally, in order to make the water purifier faucet more suitable for small and medium-sized household devices such as water purifiers with compact spatial layout, the direction in which the water pipe interface connects the mixing cavity is the length direction, the direction in which the water outlet cavity connects the mixing cavity is the height direction, and the direction perpendicular to the length and height is the width direction. It is recommended that the size of the water purifier faucet be 45-50mm in length, 35-40mm in height, and 35-40mm in width, and the water pipe diameter accessed by the water pipe interface be within 10mm.

[0046] In an embodiment, on the basis of the above-mentioned embodiment, with reference to Figure 2 , the water outlet side of the bubbler is arranged at the outlet of the water outlet cavity;

[0047] And / or, the water inlet side of the bubbler is a conical convex surface.

[0048] 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. By arranging the water outlet side of the bubbler at the outlet of the water outlet cavity, the water outlet cavity can be used to accommodate the bubbler, which can save structural space and material cost.

[0049] Optionally, the water inlet side of the bubbler is designed as a conical protruding surface. This special shape can guide and adjust the water flow entering the bubbler based on the principle of fluid mechanics.

[0050] When the mixed water flows from the mixing cavity into the bubbler, the conical protruding surface can make the water flow evenly dispersed. Compared with the flat water inlet side, the conical protruding surface can avoid the water flow concentrated in a certain point entering the bubbler, so that the water flow can pass through the filter screen or other structures inside the bubbler more evenly, improving the bubbling effect and mixing uniformity.

[0051] Under the guidance of the conical protruding surface, the water flow will form a more complex flow path, increasing the contact and mixing opportunities between water 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 finally flowing water temperature more stable and the components more uniform.

[0052] In an embodiment, on the basis of the above-mentioned embodiment, the bubbler is threadedly connected with the water outlet cavity; wherein the side wall of the bubbler is provided with external threads; and the inner wall of the water outlet cavity is provided with internal threads.

[0053] In this embodiment, the connection between the bubbler and the water outlet cavity adopts a threaded connection. When assembling the water purifier faucet, you only need to align the side wall of the bubbler with external threads with the inner wall of the water outlet cavity with internal threads from the outlet of the water outlet cavity, and then rotate according to the rotation direction of the threads. You can easily install the bubbler on the water outlet cavity. This installation method does not require complex tools and operating skills, even ordinary users can complete it by themselves.

[0054] When it is necessary to clean, replace or maintain the bubbler, it can also be disassembled from the water outlet cavity by reversing the rotation.

[0055] Threaded connections offer excellent self-locking properties, ensuring the stability of the connection between the aerator and the outlet chamber. Under continuous water flow impact and pressure changes, the friction between the threads effectively prevents the aerator from loosening or falling off. When water flows from the mixing chamber through the aerator and outlet chamber, it generates a certain amount of water flow impact and pressure fluctuation. If other connection methods are used, such as simple snap-fit ​​or sleeve connections, loosening or even falling off may occur under long-term water flow impact, leading to problems such as leakage. The tightness and stability of threaded connections ensure that the aerator remains firmly fixed to the outlet chamber under various operating conditions, guaranteeing the normal use and safety of the faucet.

[0056] Threaded connections also provide good sealing performance. When the external thread of the aerator and the internal thread of the water outlet chamber are tightly fitted, the gap between the threads can form a certain sealing effect through the screwing action, reducing the possibility of water leakage from the connection point. To further improve the sealing performance, sealing materials such as PTFE tape can be wrapped around the threads to enhance the sealing effect and ensure that water flows out of the aerator only along the designed path, improving the efficiency and reliability of the faucet.

[0057] In one embodiment, based on the above embodiments, referring to Figure 4 The mixing chamber is equipped with a detachable locking cover, and the locking cover has a mounting position for the temperature sensor. When the locking cover locks the mixing chamber, the probe end of the temperature sensor, which is located in the mounting position, is inserted into the mixing chamber, and the data end of the temperature sensor is located outside the mixing chamber.

[0058] In this embodiment, the detachable locking cover is a cover structure that can be connected and disconnected from the mixing chamber. Although the locking cover is detachable, it can achieve a secure lock when installed on the mixing chamber. This lock ensures a tight connection between the cover and the chamber, preventing water leakage or preventing external impurities from entering the chamber.

[0059] Optionally, the connection between the locking cover and the mixing chamber can be a snap-fit ​​connection, a threaded connection, a magnetic connection, etc. A snap-fit ​​connection is preferred, and the following explanation uses it as an example: The cover has snaps on its edge, and the chamber opening has corresponding slots. During installation, align the cover with the chamber, then rotate the cover to engage the snaps in the slots, thus locking it in place. During disassembly, rotate the cover in the opposite direction to disengage the snaps from the slots, allowing the cover to be removed.

[0060] By incorporating a temperature sensor mounting location within the locking cover, space is efficiently utilized and the layout is optimized. The temperature sensor is a crucial component for monitoring water temperature within the mixing chamber. Directly installing it inside the mixing chamber could occupy internal space, affecting water mixing and flow path. By placing the mounting location on the locking cover, the sensor's probe can be inserted into the mixing chamber for accurate temperature measurement without interfering with the internal structure or water flow, resulting in a more compact and rational design for the entire water purifier faucet.

[0061] The locking cover features a mounting position for the temperature sensor, facilitating easy installation and replacement. Installation is simple: just place the sensor in the mounting position and ensure the probe end is inserted into the mixing chamber. When the temperature sensor malfunctions or requires calibration or replacement, complex disassembly of the mixing chamber is unnecessary; simply open the locking cover to access the sensor, improving maintenance efficiency and convenience.

[0062] When the lid is closed to lock the mixing chamber, the probe of the temperature sensor is inserted into the mixing chamber, allowing direct contact with the water flow and thus accurately measuring the temperature of the mixed water. This direct contact avoids measurement errors caused by intermediate media or environmental factors, ensuring the accuracy and reliability of the temperature measurement. This is significant for applications requiring precise water temperature control, such as preparing formula or brewing tea, providing users with more accurate water temperature information.

[0063] The temperature sensor's data terminal is located on the outside of the mixing chamber, facilitating connection to external control circuits or display devices. The data terminal can transmit the measured temperature data to the water purifier's control module via wires or other means, enabling real-time monitoring and control of the water temperature. Simultaneously, the temperature data can also be transmitted to a display device, allowing users to intuitively understand the temperature of the mixed water. This placement avoids complex data transmission wiring within the mixing chamber, reducing the possibility of line faults and interference, and improving the stability and reliability of data transmission.

[0064] In one embodiment, based on the above embodiment, the water pipe interface has a built-in water pipe fitting.

[0065] In this embodiment, the built-in water pipe fitting in 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 fitting can fit tightly against the outer wall of the water pipe, filling the gap between the water pipe and the interface and preventing water leakage at the connection point.

[0066] Pipe fittings serve to protect water pipes. During the insertion of the pipe into the connector, the fitting reduces friction between the pipe and the connector edge, preventing scratches or wear on the pipe surface. This protective effect is particularly noticeable for softer materials such as plastic pipes.

[0067] Built-in pipe fittings enhance the stability of the connection between the water pipe and the interface. They provide additional friction, securing the pipe more firmly within the interface and preventing it from loosening or detaching under water flow. This stability is especially important in water purifiers, where the water pressure is high and the pipes are thin. An unstable pipe connection can lead to sudden pipe detachment, causing flooding and other safety hazards. The use of pipe fittings significantly improves connection reliability, ensuring the safe operation of the water system.

[0068] In one embodiment, based on the above embodiment, a leak-proof plug is provided between the water pipe fitting and the mixing chamber inlet.

[0069] In this embodiment, a leak-proof plug is installed between the water pipe fitting and the mixing chamber inlet to further enhance the sealing performance of the connection. Although the water pipe fitting itself can achieve a certain degree of sealing, with the increase of usage time and the influence of factors such as water flow impact and pressure changes, tiny gaps may appear at the connection, leading to leakage. The leak-proof plug can fill these potential gaps, preventing water from seeping out of the connection and ensuring that all water flows into the mixing chamber for subsequent mixing, avoiding water waste and damage to the surrounding environment and equipment caused by leakage.

[0070] When water flows through the pipe into the mixing chamber, it generates a certain amount of impact and vibration. The leak-proof plug has a certain degree of elasticity, which can act as a buffer and shock absorber. It can absorb the energy generated by the water flow impact, reduce the impact of vibration on the pipe fittings, the mixing chamber inlet, and the entire connection structure, reduce the risk of component loosening or damage caused by vibration, and extend the service life of related components.

[0071] This utility model further proposes a water purifier, which includes a water purifier faucet. The specific structure of the water purifier faucet is as described in the above embodiments. Since this water purifier adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0072] The hot water outlet and the normal temperature water outlet of the water purifier are respectively connected to the two water pipe interfaces of the water purifier faucet.

[0073] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
