Description

Technical Field

[0001] This application relates to the field of drinking water equipment technology, and in particular to a water outlet structure and drinking water equipment. Background Technology

[0002] Pipeline water dispensers, also known as piped water purifiers or wall-mounted piped water purifiers, are generally used in homes, offices, schools, etc., in conjunction with water purification equipment. They have a built-in water tank where clean water is pre-filled for drinking.

[0003] Currently, water dispensers have introduced a true boiling function, which means that the water temperature at the outlet of the water dispenser will reach 100 degrees Celsius, and a large amount of water vapor will be generated after the water temperature reaches 100 degrees Celsius.

[0004] To solve the aforementioned water vapor separation problem, a silicone vent pipe is typically connected to the water outlet for venting. This means that condensate produced inside the silicone pipe is discharged into the water tank. However, silicone pipes are prone to producing an odor at high temperatures, and this odorous condensate discharged into the tank can affect the water quality. Furthermore, due to the limitations of the silicone hose, it is not only prone to deformation, leading to loosening and detachment and leaks, but it is also easily damaged, causing numerous after-sales issues. Utility Model Content

[0005] Therefore, it is necessary to provide a water outlet structure and drinking water equipment to address the problem of odor caused by the traditional method of using silicone exhaust pipes to discharge steam into the water tank to solve the above-mentioned water vapor separation problem.

[0015] In one embodiment, a guide plate is also provided in the cavity of the body, and the guide plate is correspondingly arranged with the first water inlet connector to guide the liquid flowing from the first water inlet connector into the cavity into the fluid channel;

[0016] The main body is also provided with an auxiliary exhaust pipe. One end of the auxiliary exhaust pipe is located in the cavity and communicates with the exhaust channel, while the other end passes through the side wall of the main body and communicates with the outside. The guide plate is located between the first water inlet connector and the end of the auxiliary exhaust pipe located in the cavity along the axial direction of the first water inlet connector.

[0017] In one embodiment, the auxiliary exhaust pipe extends axially along the direction of gravity;

[0018] And / or, the guide plate extends toward the surface of the first water inlet connector in the direction of gravity.

[0019] In one embodiment, the body between the inlet and the outlet has a bend, the inner sidewall of the bend has a guide surface, and the outer sidewall of the bend has an overflow channel.

[0020] The water outlet structure also includes a water outlet nozzle, which is detachably connected to the water outlet of the main body. The inner wall of the water outlet nozzle forms a gap with the outer wall of the main body at the water outlet, and the gap connects the overflow channel and the outside.

[0021] In one embodiment, the water outlet structure further includes a temperature measuring element, which is inserted through the body and the measuring end of the temperature measuring element is located in the cavity. The distance between the measuring end and the guide surface is between 0.5mm and 1mm.

Additionally, by inserting the second end of the exhaust pipe into the exhaust pipe of the main body of the drinking water equipment, the entire structure is directionally guided to the water tank cavity for condensation, preventing steam from being directly emitted to the outside of the drinking water equipment and causing water condensation or scalding risks.

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] As mentioned in the background section, when a water dispenser supplies 100°C boiling water, the high-temperature water flow generates a large amount of steam. Currently, the industry commonly uses a silicone vent pipe connected to the outlet to achieve steam separation, allowing the steam to be guided through the silicone pipe into the water tank for condensation, preventing steam overflow. However, this solution has significant drawbacks. First, the silicone material is prone to aging after prolonged contact with 100°C high-temperature steam, releasing organic odor substances. Second, the condensate in the vent pipe carries these odor substances back into the water tank, contaminating the stored purified water. Furthermore, these odor substances may alter the taste of the water, and long-term accumulation could even affect drinking water safety.

[0049] To address the aforementioned problems, this application provides a water outlet structure and drinking water device. By dividing the cavity into exhaust channels and fluid channels with different paths, it ensures that the water flow and steam paths are independent, preventing water from flowing into the exhaust channel and avoiding steam affecting the stability of the water flow rate, thus ensuring the safety of the drinking water device. Furthermore, the exhaust pipe in this embodiment can be made of hard rubber or integrated with the main body. Compared to traditional silicone pipes, it is less prone to aging and decomposition under high-temperature steam, preventing condensate from carrying odors and contaminating the water in the tank, thus improving drinking water hygiene. Moreover, the exhaust pipe in this embodiment protrudes from the side wall of the main body, allowing for easy connection to the exhaust pipe inside the main body of the drinking water device via a plug-in method, facilitating installation and improving assembly efficiency. Additionally, by inserting the second end of the exhaust pipe into the exhaust pipe of the main body of the drinking water device, the entire structure is directionally guided to the water tank cavity for condensation, preventing steam from being directly emitted to the outside of the drinking water device and causing water condensation or scalding risks.

[0050] See Figure 1 and Figure 5 , Figure 1 This is a cross-sectional structural diagram of a water outlet structure provided according to some embodiments of this application. Figure 5 This is a disassembled structural diagram of the main body and water outlet structure of a drinking water device according to some embodiments of this application. One embodiment of this application first provides a water outlet structure applied to a drinking water device. The main body 700 of the drinking water device may include a heating element, an ice-making element, and a water tank, enabling instant heating and cooling of the liquid within the pipeline, thereby providing drinking water at multiple temperatures. In this embodiment, the water outlet structure is detachably connected to the main body 700 of the drinking water device, facilitating the discharge of liquid from the device for easy scooping. The water outlet structure may include a body 100 and an exhaust pipe 200.

[0051] The main body 100 has a cavity 110, within which an exhaust channel 111 and a fluid channel 112 are defined. The main body 100 has an inlet 120 and an outlet 130 connected to the cavity 110, and the fluid channel 112 connects the inlet 120 and the outlet 130. The first end of the exhaust pipe 200 is located on the side wall of the main body 100 and is connected to the exhaust channel 111. The second end of the exhaust pipe 200 protrudes from the outer wall of the main body 100 and is configured to be inserted into the exhaust pipe 720 of the main body 700 of the drinking water equipment to guide the steam in the cavity 110 into the exhaust pipe 720.

[0052] It is understood that the body 100 can be integrally formed by injection molding, and an inlet 120 and an outlet 130, as well as an exhaust port for installing the exhaust pipe 200, can be pre-reserved during the injection molding process. Of course, the body 100 can also be formed by splicing two symmetrical upper and lower body pieces. Regardless of the formation method, a cavity 110 is formed inside the body 100. The cavity 110 is mainly used to discharge water flow. Of course, in this embodiment, the upper part of the cavity 110 is also used to discharge water vapor.

[0053] For ease of understanding, the cavity 110 of the main body 100 is virtually divided into an exhaust channel 111 and a fluid channel 112. The specific ratio of the fluid channel 112 to the exhaust channel 111 needs to be defined according to the flow rate of the liquid and the amount of water vapor generated. In this embodiment, after the main body 100 is installed on the drinking water device, the cavity 110 is roughly divided into an exhaust channel 111 and a fluid channel 112 based only on the direction of gravity, and the exhaust channel 111 is located above the fluid channel 112.

[0054] The inlet 120 can be located on the side wall of the main body 100 to facilitate connection with the main body 700 of the drinking water device. Liquid within the drinking water device flows into the cavity 110 through the inlet 120 and out through the outlet 130, meaning the outlet 130 is located at the bottom of the main body 100. In this embodiment, multiple inlets 120 can be provided, for example, two: one for hot water and one for cold water; alternatively, three can be provided: one for hot water, one for room temperature water, and one for cold water. The specific number of inlets 120 is not specified here.

[0055] Correspondingly, in order to accelerate the discharge of water vapor in the cavity 110, the exhaust pipe 200 is set above the main body 100. At the same time, in order to ensure docking with the main body 700 of the drinking water equipment, the exhaust pipe 200 and the water inlet 120 can be set on the same side wall of the main body 100, or the exhaust pipe 200 can be oriented in the same direction as the water inlet 120, which is conducive to docking and installation, thereby improving assembly efficiency.

[0056] In this embodiment, the exhaust pipe 200 can be made of high-temperature resistant hard plastic (such as PP, PC, etc., which can withstand 100°C steam and does not easily produce odors). Its first end is fixed to the side wall of the main body 100, for example, by snap-fit ​​or threaded connection, and communicates with the exhaust channel 111 in the cavity 110. A sealing ring can be set at the interface to prevent steam leakage. The second end protrudes from the outer wall of the main body 100. This protruding section needs to be inserted into the exhaust pipe 720 of the main body 700 of the water drinking device to guide the steam in the cavity 110 into the exhaust pipe 720, specifically into the water storage cavity 710 of the main body 700 of the water drinking device. Of course, in addition to the above-mentioned method of separately setting the exhaust pipe 200 in the main body 100, the exhaust pipe can also be integrally formed with the main body 100. Since the main body 100 is usually made of high-temperature resistant hard plastic, the high-temperature (steam) resistance of the exhaust pipe 200 can also be guaranteed. The selection of the aforementioned exhaust pipe 200 eliminates the need for a flexible hose, thereby preventing steam from returning to the water storage chamber 710 and causing an unpleasant odor due to hose aging. Furthermore, it facilitates the installation of the water outlet structure and the main body 700 of the drinking water equipment.

[0057] More specifically, in this embodiment, the exhaust pipe 200 can be directly inserted near the water storage cavity 710 inside the main body of the water dispenser 700. For example, the exhaust pipe 200 can be tilted at a certain angle, with the second end of the exhaust pipe approaching the top of the water storage cavity 710. Guided by the exhaust pipe 720 inside the main body of the water dispenser 700, it can quickly guide the steam in the cavity 110 to the water storage cavity 710. This arrangement reduces the number of exhaust pipes 720 inside the main body of the water dispenser 700, which helps to reduce the design length of the exhaust pipe 720, freeing up more space inside the main body of the water dispenser 700 and saving volume. It should be noted that the exhaust pipe 720 inside the main body of the water dispenser 700 can be a channel (high-temperature resistant rigid plastic) integrally formed by the main body 700, or it can be a rigid pipe made of high-temperature resistant rigid plastic that is separately installed inside the main body of the water dispenser 700. This ensures that all channels through which water vapor flows are designed as high-temperature resistant rigid pipes, thereby solving the problem of odor after water vapor condensation.

[0058] It should be noted that the large amount of steam generated after boiling water flows out of the inlet 120 first passes through the exhaust pipe 200. The special design of the exhaust pipe 200 mentioned above can prevent it from producing odors under the action of high temperature water vapor.

[0059] In this embodiment, the water outlet structure needs to be used in conjunction with a water dispenser (such as a water purifier). When the water purifier's heating tank heats the water to 100°C, the water vaporizes to produce a large amount of steam. The steam enters the exhaust pipe 200 through the exhaust channel 111, flows into the pipe through the first end of the exhaust pipe 200, and then exits into the water storage chamber 710 through the second end. Because the temperature of the water storage chamber 710 is relatively low, the steam condenses into liquid water inside the chamber. The condensate is then stored in the water storage chamber 710, preventing direct discharge to the outside of the water dispenser that could cause scalding or water vapor condensation.

[0060] The water outlet structure provided in this embodiment divides the cavity 110 into an exhaust channel 111 and a fluid channel 112 with different paths. This ensures that the water flow and steam paths are independent, preventing water from flowing into the exhaust channel 111 and avoiding steam affecting the stability of the water flow rate, thus ensuring the safety of the drinking water equipment. Furthermore, the exhaust pipe 200 in this embodiment can be made of hard rubber or integrally formed with the body 100. Compared to traditional silicone pipes, it is less prone to aging and decomposition under high-temperature steam, preventing condensate from carrying odors and contaminating the water tank, thus improving drinking water hygiene. Moreover, the exhaust pipe 200 protrudes from the side wall of the body 100, allowing for easy connection to the exhaust pipe 720 inside the main body 700 of the drinking water equipment via a plug-in method, facilitating installation and improving assembly efficiency. Additionally, by inserting the second end of the exhaust pipe 200 into the exhaust pipe 720 of the main body 700 of the drinking water equipment, the entire structure is directionally guided to the water tank cavity for condensation, preventing steam from being directly emitted to the outside of the drinking water equipment and causing condensation or scalding risks.

[0061] Below, we will combine the appendix Figure 1 - Appendix Figure 3 The specific structure of the water outlet structure provided in the embodiments of this application will be described in detail.

[0062] like Figure 1 and Figure 2 As shown, Figure 2 This is a schematic diagram of the overall structure of the water outlet structure provided according to some embodiments of this application. In some embodiments, the water outlet structure further includes a water inlet pipe 500, which is disposed at the water inlet 120; an exhaust channel 111 and a fluid channel 112 are arranged sequentially along the direction of gravity; along the direction of gravity, the water inlet pipe 500 is located between the water outlet 130 and the exhaust pipe 200.

[0063] Specifically, the cavity 110 is divided into upper and lower regions along the direction of gravity. The upper part is the exhaust channel 111, and the lower part is the fluid channel 112, which connects the inlet 120 and the outlet 130.

[0064] The inlet pipe 500 can be made of high-temperature resistant rigid plastic. Based on the placement of the exhaust channel 111 and the fluid channel 112 in the above embodiment, the liquid flows downwards along the direction of gravity, while the steam flows upwards away from gravity. The inlet pipe 500 is positioned between the outlet 130 and the exhaust pipe 200, allowing for simultaneous liquid outflow from the outlet 130 and steam discharge from the exhaust pipe 200.

[0065] In this embodiment, the exhaust channel 111 and the fluid channel 112 are arranged in layers along the direction of gravity, utilizing gravity to naturally separate steam and water flow, reducing interference between the two and improving drainage and exhaust efficiency. Furthermore, the water inlet pipe 500 is located between the exhaust pipe 200 and the water outlet 130, which shortens the water flow path.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the first end of the water inlet pipe 500 is located on the side wall of the main body, and the second end of the water inlet pipe 500 protrudes from the outer wall surface of the main body. The second end of the water inlet pipe 500 is configured to be inserted into the liquid pipe of the drinking water device body 700. The axial direction of the exhaust pipe 200 is parallel to the axial direction of the water inlet pipe 500 and intersects the direction of gravity.

[0067] Specifically, the first end of the water inlet pipe 500 is fixed to the water inlet 120 on the side wall of the main body 100 by interference fit or threaded connection, and a sealing ring is provided at the interface. The second end of the water inlet pipe 500 protrudes from the outer wall of the main body 100 and is in the form of a tubular structure, which is used to insert liquid pipes into the main body 700 of the drinking water equipment, such as hot water connectors and cold water connectors of the water storage chamber 710 in the drinking water equipment.

[0068] The inlet pipe 500 and the vent pipe 200 can extend horizontally. This arrangement allows the vent pipe 200 and the inlet pipe 500 to be simultaneously inserted into the corresponding vent pipe 720 and liquid pipe when the water outlet structure is connected to the main body 700 of the drinking water equipment, thus improving assembly efficiency. More specifically, the vent pipe 200 and the inlet pipe 500 are axially parallel, and the orientation of the vent pipe 200 is the same as that of the inlet pipe 500. Installation can be completed through a single-direction insertion action, reducing assembly steps and improving assembly efficiency.

[0069] In some embodiments, the exhaust pipe 200 is detachably connected to the body 100; or, the exhaust pipe 200 is integrally formed with the body 100.

[0070] Specifically, an external thread can be provided at the first end of the exhaust pipe 200, and an internal thread can be provided at the exhaust port on the side wall of the body 100. The pipe can be tightened and fixed by the thread, and a high-temperature resistant sealing ring (such as fluororubber) can be installed at the connection. Alternatively, a snap-fit ​​structure can be adopted, with an elastic retaining ring at the end of the exhaust pipe 200, which can be fixed in conjunction with the retaining groove of the body 100 for easy maintenance and replacement.

[0071] In addition to the aforementioned detachable connection method, the main body 100 and the exhaust pipe 200 can also be integrally molded by injection molding, with the material being PP or PC. The whole structure is resistant to high temperature and has no assembly gaps 301, which avoids steam leakage and also helps to improve structural strength.

[0072] like Figure 1 As shown, in some embodiments, the water inlet pipe 500 includes a first water inlet connector 510 and a second water inlet connector 520, the first water inlet connector 510 being configured to deliver hot water and the second water inlet connector 520 being configured to deliver cold water.

[0073] It is understandable that the first water inlet connector 510 and the second water inlet connector 520 can be arranged side by side on the side wall of the main body 100, with the opening direction being the same, and respectively connecting to the hot water pipe and the cold water pipe inside the main body 700 of the drinking water equipment. The outer wall of the water inlet connector is provided with an annular groove to install a sealing ring to ensure a seal.

[0074] This embodiment supports independent supply of hot and cold water to meet the needs of drinking water at multiple temperatures, and the integrated design of the dual connectors reduces assembly errors.

[0075] like Figure 1 As shown, in some embodiments, a flow guide plate 140 is also provided in the cavity 110 of the body 100. The flow guide plate 140 is correspondingly provided with the first water inlet connector 510 to guide the liquid flowing from the first water inlet connector 510 into the cavity 110 to the fluid channel 112. The body 100 is also provided with an auxiliary exhaust pipe 150. One end of the auxiliary exhaust pipe 150 is located in the cavity 110 and communicates with the exhaust channel 111. The other end passes through the side wall of the body 100 and communicates with the outside. Along the axial direction of the first water inlet connector 510, the flow guide plate 140 is located between the first water inlet connector 510 and the auxiliary exhaust pipe 150 at the end of the cavity 110.

[0076] Specifically, the diversion plate 140 can also be understood as a baffle set corresponding to the first water inlet connector 510. The diversion plate 140 can be a straight plate structure, fixed in the cavity 110 of the body 100. More specifically, the first water inlet connector 510 is a hot water connector designed above the second water inlet connector 520 (cold water connector). Since the cold water flowing out of the second water inlet connector 520 does not contain steam, the cold water will flow directly out of the outlet 130 along the fluid channel 112. The hot water flowing out of the first water inlet connector 510 will generate a large amount of water vapor. In order to prevent some hot water from splashing out from the exhaust pipe 200 and the auxiliary exhaust pipe 150, the water flowing out of the first water inlet connector 510 will be blocked by the diversion plate 140 when it enters the cavity 110, restricting the water flow into the fluid channel 112 and preventing direct impact on the exhaust channel 111. In this embodiment, the diversion plate 140 is made of high-temperature resistant plastic, and the edges are rounded to reduce water flow resistance.

[0077] The auxiliary exhaust pipe 150 is installed at the bottom of the main body 100, with one end extending into the area of ​​the exhaust channel 111 and the other end located outside the main body 100, communicating with the outside air. It serves as a backup exhaust path; when the exhaust pipe 200 is blocked, steam can be discharged through the auxiliary exhaust pipe 150, thereby improving equipment reliability. In this embodiment, the outlet of the auxiliary exhaust pipe 150 is located at the bottom of the main body 100, which can prevent steam from scalding the user.

[0078] In addition, in this embodiment, the diversion plate 140 is placed between the first water inlet connector 510 and the inlet of the auxiliary exhaust pipe 150 to form a physical barrier between the two and prevent hot water from spraying into the auxiliary exhaust pipe 150.

[0079] like Figure 1 As shown, in some embodiments, the auxiliary exhaust pipe 150 extends axially along the direction of gravity. Specifically, the auxiliary exhaust pipe 150 extends along the direction of gravity, and its outlet is located on the lower side wall of the main body 100, which facilitates the natural dripping of condensate to the bottom of the water tank, avoiding water accumulation. Moreover, the vertical layout can reduce the residence time of steam in the auxiliary exhaust pipe 150 and improve condensation efficiency.

[0080] like Figure 1 As shown, in some embodiments, the guide plate extends along the direction of gravity toward the surface of the first water inlet connector 510. Specifically, the guide plate 140 extends vertically along the direction of gravity toward the surface of the first water inlet connector 510, with the plate surface perpendicular to the water flow direction, so that hot water falls vertically after hitting the plate surface and is accurately introduced into the fluid channel 112, reducing water flow scattering and ensuring that the exhaust channel 111 is free from water flow interference.

[0081] like Figure 1 and Figure 3 As shown, Figure 3This is a schematic diagram of the bottom structure of a water outlet structure provided according to some embodiments of this application. In some embodiments, the body 100 between the inlet 120 and the outlet 130 has a bend 160, the inner sidewall of the bend 160 has a guide surface 161, and the outer sidewall of the bend 160 has an overflow channel 170; the water outlet structure also includes a spout 300, which is detachably connected to the outlet 130 of the body 100, and the inner wall of the spout 300 and the outer wall of the body 100 at the outlet 130 form a gap 301, which connects the overflow channel 170 and the outside.

[0082] Understandably, the main body 100 forms a 90°-120° bend 160 near the outlet 130. The inner sidewall of the bend 160 is a smooth guide surface 161, guiding the water flow to the outlet 130. An overflow channel 170 is formed between the outer sidewall of the bend 160 and the outer wall of the main body 100. The function of the overflow channel 170 is that water flows out from the outlet 130 along the guide surface 161. When the outlet 130 is blocked by foreign objects or the water pressure is too high, water will flow into the overflow channel 170, and the water in the overflow channel 170 will flow out from the auxiliary outlet 130 (the aforementioned gap 301), thereby preventing damage caused by excessive water pressure in the cavity 110.

[0083] The water outlet 300 can be threaded to the water outlet 130 of the main body 100. Its inner wall and the outer wall of the water outlet 130 of the main body 100 form an annular gap 301. This gap 301 (auxiliary water outlet) is connected to the overflow channel 170, which can discharge the water in the overflow channel 170 in a timely manner. In this example, the auxiliary water outlet is coaxially arranged with the water outlet 130.

[0084] In this embodiment, the design of the bend 160 and the overflow channel 170 forms a redundant drainage path, preventing equipment damage due to blockage and improving operational safety. At the same time, the smooth guide surface 161 reduces water flow resistance, ensuring the main outlet 130 remains unobstructed, while preventing water flow from impacting the overflow channel 170 and causing abnormal drainage.

[0085] like Figure 1 As shown, in some embodiments, the water outlet structure further includes a temperature measuring element 400, which is inserted through the body 100, and the measuring end of the temperature measuring element 400 is located in the cavity 110, with the distance between the measuring end and the guide surface 161 being between 0.5mm and 1mm.

[0086] Specifically, the temperature measuring element 400 can be a thermistor, which is installed in the upper part of the body 100, with the measuring end extending into the cavity 110. The distance between the thermistor and the flow guiding surface 161 can be 0.5mm, 0.7mm, 0.9mm, or 1mm to ensure direct contact with the water flow. Of course, the temperature measuring element 400 can be wrapped with a high-temperature resistant protective sleeve to prevent steam corrosion.

[0087] In this embodiment, the temperature measuring device 400 can monitor the water temperature inside the cavity 110 in real time, providing data support for the heating control of the drinking water equipment.

[0088] In some embodiments, the exhaust pipe 200 is made of a rigid plastic material. Specifically, the exhaust pipe 200 can be made of a rigid plastic material such as PP or PC, which can withstand high temperatures of 120°C and a heat distortion temperature greater than or equal to 100°C. It does not release odors even after long-term contact with steam, ensuring the purity of the condensate and protecting the water quality in the water storage chamber 710.

[0089] Based on the same inventive concept, this application also provides a drinking water device, such as... Figure 4 and Figure 5 As shown, Figure 4 This is a cross-sectional structural diagram of a drinking water device according to some embodiments of this application. The drinking water device may include a main body 700 and the water outlet structure in the above embodiments.

[0090] The main body 700 has an interconnected water storage chamber 710 and an exhaust pipe 720 inside; the exhaust pipe 200 of the water outlet structure is inserted into the exhaust pipe 720; wherein, the exhaust pipe 720 is configured to guide the steam in the water outlet structure to the water storage chamber 710.

[0091] Understandably, the main body 700 can be injection molded from a high-temperature resistant rigid plastic material such as PP or PC, and it integrates a water storage chamber 710 and an exhaust pipe 720, which are connected through the exhaust outlet of the exhaust pipe 720. The water storage chamber is mainly used to store purified water, and the chamber wall is marked with a maximum liquid level line 711. The exhaust pipe 720, as an independent channel within the main body 700, can be integrally formed within the main body 700 or a rigid plastic pipe separately installed within the main body 700.

[0092] In the above embodiment, the exhaust pipe 200 of the water outlet structure is adapted to be inserted into the exhaust pipe 720, and the two can form a steam-sealed channel through the sealing ring.

[0093] It should be noted that in this embodiment, the exhaust pipe 720 can be horizontally installed within the main body 700, and the outlet of the inclined exhaust pipe 200 can be inserted into the exhaust pipe 720 to facilitate the diversion of steam to the water storage chamber 710. Of course, to save space and make the structural design more reasonable, the exhaust pipe 720 can be vertically installed within the main body 700, which can reduce the volume of the water outlet structure.

[0094] like Figure 4 As shown, in some embodiments, the exhaust pipe 720 includes an inlet end and an outlet end. The inlet end is configured to be sealed to the second end of the exhaust pipe 200; the outlet end is connected to the water storage chamber 710; the axial direction of the exhaust pipe 200 extends along the direction of gravity, and the outlet end is higher than the highest liquid level line 711 of the water storage chamber 710.

[0095] Specifically, the air inlet is located on the side wall of the main body 700 and has a circular interface. It is sealed to the second end of the exhaust pipe 200 of the water outlet structure by means of threads or snap-fit, and a fluororubber sealing ring is provided at the interface. The air outlet extends upward to the top area of ​​the water storage chamber 710, and the opening is a certain distance above the highest liquid level line 711 of the water storage chamber 710 to prevent water from flowing back into the exhaust pipe 720 when the water level in the water storage chamber 710 is too high.

[0096] The exhaust pipe 720 extends axially along the direction of gravity, with the air inlet located on the lower side wall of the main body 700 and the air outlet located on the top of the water storage chamber 710, forming a steam flow path that enters from the bottom and exits from the top.

[0097] In some embodiments, the exhaust pipe 720 is made of rigid rubber. Specifically, the exhaust pipe 720 may be made of food-grade rigid rubber to ensure high temperature resistance and chemical stability, and to prevent odor release. The rigid rubber pipe eliminates the odor problem caused by molecular chain breakage in silicone pipes at high temperatures, and prevents condensate from carrying odors and contaminating the water quality of the water storage chamber 710.

[0098] In some embodiments, the exhaust pipe 720 is an integrally formed channel within the main body 700. Specifically, the exhaust pipe 720 can be part of the injection molding mold of the main body 700, molded synchronously with the main body 700, without the need for subsequent assembly. This integrated design eliminates the assembly gap 301 between the exhaust pipe 720 and the main body 700, preventing the risk of steam leakage. Furthermore, this design is compact and saves internal space in the main body 700, which helps improve the overall sealing of the drinking water equipment and reduces the leakage failure rate.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
