It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0047] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0048] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0050] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0051] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0052] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0053] This disclosure provides a water outlet device and a water treatment device, wherein the water treatment device includes the water outlet device. For ease of understanding, the specific structure and working principle of the water outlet device will be described in detail below when describing the water treatment device of this disclosure, and will not be described separately.

[0054] The water treatment equipment disclosed herein can be various types of water treatment equipment such as water purifiers, ice makers, water heaters, integrated water purifiers and heaters, and sparkling water machines. This water treatment equipment has a water outlet device, which can be a faucet, specifically a smart faucet. In a specific application scenario where the water treatment equipment is an integrated water purifier and heater, the unit can be placed under the user's kitchen sink, and the water outlet device is a faucet placed above the countertop. The user can interact with the smart faucet to control whether it dispenses room temperature or hot water.

[0055] In one specific embodiment of this disclosure, the water treatment equipment may include a filtration device and a heating device. The filtration device is connected to both the heating device and a room temperature water pipe 61. The filtration device purifies tap water into pure water suitable for direct drinking. The pure water can be conveyed to the heating device for heating, or directly conveyed to the outlet device for discharge through the room temperature water pipe 61. The heating device is connected to a hot water pipe 62, thereby conveying hot water to the outlet device for discharge through the hot water pipe 62.

[0056] refer to Figure 1 The water outlet device includes a rocker arm 100 and a column 200, the rocker arm 100 being rotatably connected to the column 200. The rocker arm 100 extends horizontally, and the end of the rocker arm 100 away from the column 200 is used for water outlet; the column 200 extends vertically, such as... Figure 1 As shown, a mounting screw 91 is provided at its bottom end, and a threaded mounting nut 92 is provided on the mounting screw 91. The mounting nut 92 can be used to fix the entire water outlet device to the kitchen sink. By setting the mounting screw 91 and mounting nut 92 to be relatively adjustable, it can adapt to various installation scenarios of different sizes.

[0057] refer to Figure 2 and Figure 3 A water outlet assembly 1 is provided at the end of the rocker arm 100, with its outlet facing downwards. The rocker arm 100 is connected to the inner cavity of the column 200, which contains independent ambient temperature water pipes 61 and hot water pipes 62. The inlet ends of the ambient temperature water pipes 61 and 62 can be connected to the corresponding outlets on the water treatment equipment, and their outlet ends can be connected to the water outlet assembly 1, allowing the water outlet assembly 1 to selectively discharge ambient temperature water or hot water. It should be noted that this disclosure only takes ambient temperature water or hot water as an example. When the water treatment equipment is other equipment, the water outlet assembly 1 can also be used to discharge other types of liquids such as cold water or aerated water. In this case, the inner cavities of the rocker arm 100 and the column 200 should be equipped with corresponding pipelines.

[0058] refer to Figures 4 to 7 ,as well as Figure 10 and Figure 11 The water outlet assembly 1 includes a first water outlet 11, a second water outlet 12, and a grille assembly 16. The first water outlet 11 has a first flow channel 101 and is configured to fit within the inner cavity of the second water outlet 12, with the outer wall of the first water outlet 11 and the inner wall of the second water outlet 12 forming a second flow channel 102. The grille assembly 16 is configured to be positioned at the outlet of the second flow channel 102. The first flow channel 101 and the second flow channel 102 are separated from each other by the obstruction of the first water outlet 11, allowing different liquids to flow into each channel. For example, the first flow channel 101 can be used for room temperature water, while the second flow channel 102 can be used for hot water.

[0059] like Figure 6 and Figure 7 As shown, a pipe connector 110 communicating with the first flow channel 101 is provided on the side wall of the first water outlet 11. The pipe connector 110 is located in the second flow channel 102 and abuts against the inner wall of the second water outlet 12 to separate the first flow channel 101 and the second flow channel 102. Specifically, the second water outlet 12 is provided with a first water inlet 121. The pipe connector 110 is configured to extend in the second flow channel 102 to connect with the first water inlet 121. Liquid entering from the first water inlet 121 is configured to flow out after passing through the pipe connector 110 and the first flow channel 101. Taking the first water inlet 121 as a room temperature water inlet as an example, the inlet end of the first water inlet 121 can be interference-fitted to the room temperature water pipe 61 through a silicone tube. Room temperature water can flow into the first flow channel 101 sequentially through the room temperature water pipe 61, the first water inlet 121, and the pipe connector 110, and then be discharged.

[0060] In one specific embodiment of this disclosure, a water inlet sealing ring 13 may be provided at the position where the pipe connector 110 is connected to the first water inlet 121. The pipe connector 110 is configured to abut against the inner wall of the second water outlet 12 through the water inlet sealing ring 13. The water inlet sealing ring 13 can seal the position where the pipe connector 110 is connected to the first water inlet 121, thereby ensuring the isolation of liquids in the first flow channel 101 and the second flow channel 102 and preventing cross-contamination.

[0061] Furthermore, such as Figure 7 As shown, the second water outlet 12 is provided with a second water inlet 122 communicating with the second flow channel 102. The second water inlet 122 is configured to be located on one side of the pipe connector 110, and a water flow accumulation zone is formed in the area of ​​the second flow channel 102 corresponding to the other side of the pipe connector 110. Taking the second water inlet 122 as a hot water inlet as an example, the inlet end of the second water inlet 122 can be interference-fitted to the hot water pipe 62 through a silicone tube. Hot water can flow into the second flow channel 102 sequentially through the hot water pipe 62 and the second water inlet 122, and then be discharged through the position of the grille assembly 16.

[0062] The second flow channel 102 is an annular flow channel formed by the outer wall of the first water outlet 11 and the inner wall of the second water outlet 12. That is, hot water entering the second flow channel 102 will flow around the first water outlet 11. Since the pipe connector 110 is located in the second flow channel 102 and is adjacent to the second water outlet 12, the liquid flowing into the second flow channel 102 from the second water inlet 122 will flow around the first water outlet 11 in a direction away from the pipe connector 110. The pipe connector 110 located in the second flow channel 102 will block the liquid in the second flow channel 102, thus forming a water accumulation zone. The liquid pressure in this zone results in more liquid than in other areas of the second flow channel 102. (Reference) Figure 16 The simulation diagram on the left shows that in the prior art, the grids on the grid assembly 16 are evenly distributed, which causes the liquid in the water accumulation area to flow out at too fast a speed, which will interfere with the water flow in other areas, resulting in unstable water pattern, water flow disturbance, splashing, and intermittent water flow.

[0063] To address the aforementioned issues, this disclosure optimizes the structure of the grille assembly 16. Specifically, as follows: Figure 11 As shown, the grille assembly 16 includes a first grille 161 corresponding to the position of the pipe connector 110, and second grilles 162 distributed circumferentially around the first grille 161; wherein the spacing between the first grilles 161 is greater than the spacing between the second grilles 162. In a specific embodiment of this disclosure, the central angle between two adjacent first grilles 161 is 20° to 25°, as shown below. Figure 11As shown, this embodiment uses 22.5°; the central angle of two adjacent second grilles 162 is 10° to 15°, and this embodiment uses 15°. The grille assembly 16 can be an integral structure with the second water outlet 12, or it can be a component independent of the second water outlet 12. One end of the first grille 161 and the second grille 162 is configured to be connected to the inner wall of the second water outlet 12, and the other end is configured to extend towards the outer wall of the first water outlet 11.

[0064] refer to Figure 16 The simulation diagram on the right shows that by increasing the spacing of the first grid 161, the liquid can flow out of the first grid 161 more easily. By setting the grid assembly 16 with uneven distribution, the hot water flowing out of the second flow channel 102 can be rectified and stabilized, making the water flowing out of the second flow channel 102 more rounded, without splashing or splitting.

[0065] Furthermore, the first grid 161 is configured to at least partially overlap with the water flow accumulation zone in the axial direction of the second flow channel 102. Specifically, the area directly below the pipe connector 110 is within the water flow accumulation zone; therefore, the first grid 161 is configured to at least partially overlap with the pipe connector 110 in the axial direction of the second flow channel 102. This disclosure increases the grid gaps corresponding to the water flow accumulation zone to reduce the outflow velocity, thereby increasing the flow rate, reducing the flow velocity, and avoiding water flow impact caused by uneven velocity. Liquid will not accumulate excessively below the pipe connector 110, thus alleviating accumulation, resulting in a stable outflow pattern and less splashing.

[0066] This disclosure establishes a first flow channel 101 and a second flow channel 102, which are separated from each other, by setting a first water outlet 11 and a second water outlet 12. The two flow channels can discharge water flows of different temperatures, preventing cross-flow between water flows of different temperatures. Furthermore, liquid in the second flow channel 102 can be blocked by the outer wall of the pipe connector 110 during flow, leading to liquid accumulation in that area. This disclosure increases the spacing of the first grille 161 at the corresponding position of the pipe connector 110, making it easier for the liquid to flow out. The water flow rate at the first grille 161 position increases, and the flow velocity decreases, avoiding water flow impact caused by uneven water velocity. The grille assembly 16 of this disclosure plays a role in rectifying and stabilizing the liquid flowing out of the outlet of the second flow channel 102, resulting in a smoother, more rounded water flow without splashing or branching, thus improving the user experience.

[0067] In one embodiment of this disclosure, reference is made to Figure 6 and Figure 12The bottom of the second water outlet 12 is constructed in the shape of a frustum. Specifically, the upper part of the inner wall of the second water outlet 12 can be cylindrical, thus simplifying the structure of the upper part of the second water outlet 12 and facilitating better filling of the second flow channel 102 by liquid. The lower part of the inner wall of the second water outlet 12 is an inverted frustum, such as... Figure 12 As shown, the angle between the truncated cone and the horizontal plane is between 70° and 90°, preferably 85°, so that the hot water flowing out from the second flow channel 102 can be better gathered together, making the water flow smooth and not branched.

[0068] like Figure 6 As shown, a baffle 14 is provided on the first water outlet 11 at a position corresponding to the bottom of the second water outlet 12. The baffle 14 is configured to form a water outlet channel 103 between itself and the bottom of the second water outlet 12. Specifically, the baffle 14 includes a cylindrical section 141 and an arc section 142 with a decreasing inner diameter from top to bottom. The cylindrical section 141 and the inner wall of the second water outlet 12 form the first water outlet channel 1031, and the arc section 142 and the inner wall of the second water outlet 12 form the second water outlet channel 1032. The size of the second water outlet channel 1032 is larger than the size of the first water outlet channel 1031.

[0069] This disclosure achieves a gradual increase in the size of the outlet channel 103 from top to bottom by incorporating a flow deflector 14, with the lower arc segment 142 of the deflector 14 gradually decreasing in size. After flowing into the outlet channel 103, the liquid in the second channel 102 first flows into the smaller first outlet channel 1031, and then into the larger second outlet channel 1032. The flow velocity of the liquid decreases when flowing into the second outlet channel 1032, thereby stabilizing the water flow at the outlet, ensuring a smooth flow, and preventing splashing and branching.

[0070] In one embodiment of this disclosure, reference is made to Figure 5 , Figure 8 and Figure 9 The first water outlet component 11 includes a first pipe section 111 and a second pipe section 112 sleeved within the first pipe section 111; the portion between the first pipe section 111 and the second pipe section 112, and the inner cavity of the second pipe section 112, are configured to jointly form a first flow channel 101. Specifically, as shown... Figure 9 As shown, the inner wall of the first pipe section 111 and the outer wall of the second pipe section 112 are connected by a partition 113. The partition 113 is configured to extend along the axial direction of the first pipe section 111 and the second pipe section 112. At least two partitions 113 are provided, and the at least two partitions 113 are configured to be distributed in the circumferential direction of the second pipe section 112.

[0071] In this embodiment, four partitions 113 may be provided, which are evenly distributed in the circumferential direction of the second pipe section 112, thereby fixing the second pipe section 112 centrally within the inner cavity of the first pipe section 111. The first water outlet 11 of this disclosure adopts a "hole-in-hole" structure, that is, the smaller diameter second pipe section 112 is embedded in the larger diameter first pipe section 111, and the second pipe section 112 is connected to the first pipe section 111 through four evenly distributed partitions 113, thereby forming two relatively independent water flow channels, one being the inner cavity of the second pipe section 112, and the other being the chamber formed between the first pipe section 111 and the second pipe section 112. The liquid flowing into the first flow channel 101 through the pipe joint 110 can partially flow into the chamber between the first pipe section 111 and the second pipe section 112, and partially flow into the inner cavity of the second pipe section 112. This achieves the effect of rectifying the liquid in the first flow channel 101 while ensuring the water outlet area, avoiding the formation of vortices in the liquid in the first flow channel 101 during the flow process, so that the water flow from the first flow channel 101 is stable, smooth, and not prone to splashing or branching.

[0072] In one embodiment of this disclosure, such as Figure 9 As shown, at least one flow divider 114 extending axially is provided on the inner wall of the first pipe section 111. The flow divider 114 is configured to be spaced from the inner wall of the second pipe section 112, and the flow divider 114 and the partition 113 are configured to be distributed circumferentially at intervals. Two adjacent partitions 113 can divide a small chamber, and at least one flow divider 114 can be provided in each small chamber. The flow divider 114 protrudes from the inner wall of the first pipe section 111, and can guide the liquid to flow along the axial direction of the first pipe section 111. In this way, the liquid in the first flow channel 101 is further rectified, so that the water flow from the first flow channel 101 is smooth, without impurities or splashing.

[0073] After each water draw, a small amount of water may remain in the water outlet component 1. This consistently damp environment can easily lead to the growth of E. coli, potentially harming human health. To address this issue, refer to... Figures 4 to 6 The present disclosure includes a sterilization component 15 disposed at the top of the first flow channel 101. The light emitted by the sterilization component 15 is configured to irradiate the outlet position at the bottom of the first flow channel 101 through the first flow channel 101. Specifically, the sterilization component 15 can be a UVC-LED sterilization module, which can emit ultraviolet light to sterilize the water outlet component 1. The sterilization component 15 can operate intermittently, that is, it can be activated once every 3-5 hours, and the irradiation time is 3-5 minutes each time. Therefore, even if the water outlet device is not used for a long time, it is not easy for E. coli to grow at its outlet, thereby improving the hygiene of the water outlet device and enhancing the safety of the user's drinking water.

[0074] In one specific embodiment of this disclosure, the top of the first water outlet 11 is provided with a through hole 115, which extends to the first flow channel 101. The bottom of the sterilization component 15 includes a protrusion 151 for emitting ultraviolet light to sterilize. The protrusion 151 can be embedded in the top of the first water outlet 11 through the through hole 115, thereby completely irradiating the first flow channel 101 and improving the sterilization effect.

[0075] In one embodiment of this disclosure, the water outlet assembly 1 is fixed to the rocker arm 100. Specifically, the rocker arm 100 includes a faucet housing 10, and the water outlet assembly 1 can be fixed to the faucet housing 10. The faucet housing 10 can be used to fix a second water outlet component 12, the bottom of which is configured to protrude from the faucet housing 10, and other components of the water outlet assembly 1 can be fixed to the second water outlet component 12.

[0076] In one embodiment of this disclosure, reference is made to Figure 3 and Figure 6 The faucet housing 10 has a mounting groove at its bottom, and the side wall of the second water outlet 12 has a radially outwardly extending mounting protrusion 124. The mounting protrusion 124 is configured to be supported on the mounting groove by a sealing member 4, so that the bottom of the second water outlet 12 protrudes from the faucet housing 10. The sealing member 4 can be interference-fitted with the mounting groove of the faucet housing 10 and the mounting protrusion 124 of the second water outlet 12, thereby firmly installing the second water outlet 12 onto the faucet housing 10 and preventing water leakage between the installation gaps.

[0077] refer to Figure 1 and Figure 14 A light-emitting component 2 is fitted onto the outside of the second water outlet 12, with at least a portion of the light-emitting component 2 exposed outside the faucet housing 10. This component is configured to emit different colors of light when corresponding liquids flow from different channels. For example, the first channel 101 is for dispensing room temperature water, and the second channel 102 is for dispensing hot water. When the first channel 101 dispenses room temperature water, the light-emitting component 2 emits blue light; when the second channel 102 dispenses hot water, the light-emitting component 2 emits red light. The color of the emitted light can be controlled according to the opening and closing status of the upstream water path corresponding to each channel, or it can be controlled based on the water temperature. This disclosure improves the intelligence of the water outlet device by incorporating the light-emitting component 2, allowing users to intuitively observe the current water dispensing status and enhancing the user experience.

[0078] The light-emitting component 2 includes a decorative element 23, and a light-emitting PCB board 21 and a light guide 22 located on the decorative element 23. The light guide 22 and the decorative element 23 are partially exposed outside the faucet housing 10. The light-emitting PCB board 21 is installed between the faucet housing 10 and the light guide 22. The light-emitting PCB board 21 may have protrusions to mate with corresponding grooves on the faucet housing 10, thus preventing the light-emitting PCB board 21 from being installed backwards or incorrectly. The light-emitting PCB board 21 controls the light emission of the light beads within the light guide 22. The light guide 22 surrounds the bottom outer side of the second water outlet 12, and its outer wall is exposed outside the faucet housing 10. The decorative element 23 is located below the light guide 22 and is used to shield the bottom surface of the light guide 22, thereby improving the overall aesthetics of the water outlet device.

[0079] The decorative element 23 is configured to be fitted over the outer side of the second water outlet element 12, and a sealing ring 5 is provided between the decorative element 23 and the second water outlet element 12. Specifically, as shown... Figure 6 As shown, an annular groove 123 is provided at the lower part of the second water outlet 12, such as... Figure 3 As shown, an annular sealing ring 5 is provided in the annular groove 123. This sealing ring 5 can be press-fitted with the second water outlet 12 and the decorative part 23, which can effectively prevent the risk of liquid splashing from the outlet of the second water outlet 12 onto the light-emitting PCB board 21.

[0080] In embodiments where the water dispensing device is a smart faucet, the water dispensing device may include a display screen assembly 3. The top of the faucet housing 10 has a mounting slot in which the display screen assembly 3 can be mounted, such as... Figure 1 As shown, the display assembly 3 can be mounted on the top surface of the rocker arm 100, facilitating user interaction with the display. Understandably, the display assembly 3 on the smart faucet is the primary component for user interaction; with prolonged use, water may enter the display assembly 3, causing it to malfunction.

[0081] To solve the above problems, in one embodiment of this disclosure, reference is made to... Figure 3 and Figure 13 The display assembly 3 includes a display cover 31 and an adhesive coating 32 fitted over the outside of the display cover 31. The display cover 31 is configured to be mounted on a mounting groove in the faucet housing 10 via the adhesive coating 32. The adhesive coating 32 fills the gap between the display cover 31 and the mounting groove, thereby improving the tightness of the installation of the display cover 31 and preventing water from entering the display assembly 3.

[0082] Furthermore, the display assembly 3 also includes a display bracket 34, a diaphragm 33, and a display PCB board 35. The display PCB board 35 is configured to be mounted on the display bracket 34. The sidewall of the display cover 31 is provided with a downwardly extending flange 311. The display bracket 34 and the diaphragm 33 are configured to cover the flange 311 of the display cover 31. This disclosure optimizes the structure of the display assembly 3. The flange 311 of the display cover 31 can completely cover the diaphragm 33, the display bracket 34, and the display PCB board 35. At the same time, the display cover 31 is provided with a full-circle adhesive 32 for installation sealing, thereby effectively preventing liquid from seeping into the diaphragm 33 and reducing the risk of functional failure of the display assembly 3.

[0083] Specifically, the diaphragm 33 can be connected to the display cover plate 31 and the display bracket 34 respectively by double-sided adhesive, and the display PCB board 35 can be connected to the display bracket 34 by potting glue, thereby fixing the diaphragm 33, the display bracket 34 and the display PCB board 35 to the display cover plate 31. The front end and the left and right sides of the display cover plate 31 can each be provided with a buckle to connect with the faucet housing 10, and the rear end of the display cover plate 31 can be provided with a fastening screw to connect with the faucet housing 10, thereby improving the reliability of the connection between the display assembly 3 and the faucet housing 10.

[0084] In one embodiment of this disclosure, such as Figure 2 As shown, an exhaust pipe 72 can also be provided in the inner cavity of the rocker arm 100 and the column 200, and an exhaust port 71 connected to the end of the exhaust pipe 72 can be provided in the middle of the rocker arm 100. In an embodiment where the water treatment equipment has a hot water supply function, the hot tank of the water treatment equipment can be connected to the exhaust pipe 72, and the hot air in the hot tank can be transported to the exhaust port 71 through the exhaust pipe 72 for discharge.

[0085] In one embodiment of this disclosure, reference is made to Figure 2 and Figure 15A rotation stop assembly 8 is provided on the column 200 to restrict the degree of freedom of the rocker arm 100 to rotate relative to the column 200. Specifically, the rotation stop assembly 8 includes a rotary connector 81, a crescent ring 82, a cylindrical pin 83, a rotary sealing ring 84, and a stop ring 85. The rotary connector 81 can be fixed to the rocker arm 100, and the crescent ring 82 is rotatably connected to the rotary connector 81. The crescent ring 82 is provided with a pin hole, and the cylindrical pin 83 can pass through the outer shell of the column 200 and the pin hole of the crescent ring 82, thereby fixing the crescent ring 82 to the column 200. When the rocker arm 100 rotates under the action of an external force, the rotary connector 81 rotates with the rocker arm 100 relative to the crescent ring 82, thereby realizing that the rocker arm 100 can rotate around the column 200. The maximum relative rotation angle between the crescent ring 82 and the rotating connector 81 can be 180°, and at this time the maximum rotation angle of the rocker arm 100 relative to the column 200 is also 180°.

[0086] In addition, the rotating connector 81 is equipped with two rotating sealing rings 84. Under the friction of the rotating sealing rings 84, the rotation can be stopped immediately while ensuring continuous and smooth rotation. The stop ring 85 is fixed to the lower end of the rotating connector 81. By setting the stop ring 85, the gap between the rocker arm 100 and the column 200 can be controlled, ensuring that the gap between the rocker arm 100 and the column 200 remains stable during long-term rotation and improving the service life of the water outlet device.

[0087] Application scenarios

[0088] In home use, the water treatment equipment is a water purifier and heater combo unit, and the water outlet is a smart faucet. The water purifier and heater combo unit can be placed under the user's kitchen sink, and the smart faucet can be placed above the countertop. Users can interact with the smart faucet to control whether it dispenses room temperature or hot water.

[0089] When a user needs to access room temperature water, the integrated water purifier and heater can pump room temperature water into the room temperature water pipe 61. The first water inlet 121 on the side wall of the first water outlet 11 can be connected to the room temperature water pipe 61 via an interference fit through a silicone tube. Room temperature water can flow into the first flow channel 101 sequentially through the room temperature water pipe 61, the first water inlet 121, and the pipe joint 110, and then be discharged for the user's use.

[0090] When a user needs hot water, the integrated water purifier and heater can pump hot water into the hot water pipe 62. The second inlet 122 on the side wall of the first outlet 11 can be interference-fitted to the hot water pipe 62 via a silicone tube. Hot water can flow sequentially through the hot water pipe 62 and the second inlet 122 into the second flow channel 102, and then be discharged through the grille assembly 16. The second flow channel 102 is an annular flow channel formed by the outer wall of the first outlet 11 and the inner wall of the second outlet 12; that is, after entering the second flow channel 102, the hot water will flow around the first outlet 11. Since the pipe connector 110 is located in the second flow channel 102 and is adjacent to the second outlet 12, the hot water flowing into the second flow channel 102 from the second inlet 122 will flow away from the pipe connector 110 and around the first outlet 11. The pipe connector 110 located in the second flow channel 102 can cause blockage of the hot water in the second flow channel 102, thus forming a water accumulation zone.

[0091] The grille assembly 16 includes a first grille 161 that at least partially overlaps with the water flow accumulation zone in the axial direction of the second flow channel 102, and a second grille 162 distributed in the circumferential direction with respect to the first grille 161; wherein the spacing of the first grille 161 is greater than the spacing of the second grille 162. This disclosure increases the spacing of the first grille 161, making it easier for hot water to flow out of the first grille 161. By setting the grille assembly 16 with an uneven distribution, it rectifyes and stabilizes the hot water flowing out of the second flow channel 102, making the hot water flowing out of the second flow channel 102 more rounded, without splashing or branching.

[0092] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein. The scope of this disclosure is defined by the appended claims.
