Description

water purifier Technical Field

[0001] The present invention relates to the technical field of water purification, in particular to a water purifier. Background Art

[0002] As people's living standards improve, more and more people are pursuing a high-quality life, and water purifiers are undoubtedly one of the best choices. Water purifiers in related technologies usually include a heater and a water vapor separator. The filtered water is heated by the heater, separated by the water vapor in the water vapor separator, and then provided to the user through the water outlet of the water vapor separator, which is also the water intake of the water purifier. However, in the water vapor separators of related technologies, there is often a situation where some accumulated water frequently flows out of the water outlet of the water vapor separator at the moment of water outage, resulting in water leakage at the water intake of the water purifier.

[0003] Summary of the Invention

[0004] An embodiment of the present application provides a water purifier, which can prevent water leakage from the water inlet of the water purifier at the moment of water outage.

[0005] An embodiment of the present application provides a water purifier, including a water vapor separator and a heater connected to the water vapor separator; the water vapor separator includes a primary water vapor separation body and a secondary water vapor separation body for performing water vapor separation, and the primary water vapor separation body and the secondary water vapor separation body are respectively constructed with a primary water vapor separation chamber and a secondary water vapor separation chamber that are connected to each other; the primary water vapor separation body is provided with a water vapor separation water inlet and a first air outlet connected to the primary water vapor separation chamber, and the secondary water vapor separation body is provided with a water vapor separation water outlet connected to the secondary water vapor separation chamber, and the water vapor separation water inlet is used to be connected to a hot water supply source; the bottom wall of the secondary water vapor separation chamber is constructed with a retention groove arranged at a distance from the water vapor separation air outlet, and the top wall of the secondary water vapor separation chamber is further provided with a third guide pipe at the connecting port connected to the primary water vapor separation chamber, and the bottom end of the third guide pipe extends into the retention groove.

[0006] The water purifier provided in the embodiment of the present application has the bottom end of the third flow guide pipe extending into the retention tank N, that is, the height of the bottom end of the third flow guide pipe is lower than the height of the edge of the notch of the retention tank N. In this way, when water intake stops, the water flowing out of the primary water vapor separation chamber K will rush out of the third flow guide pipe due to the inertia of the water flow and the adhesion characteristics of water, so that the water level in the third flow guide pipe is lower than the water level in the retention tank N (which is full of water). As time goes by, the water in the third flow guide pipe gradually stabilizes, and some of the water in the retention tank N returns to the third flow guide pipe, so that the water level in the third flow guide pipe is equal to the water level in the retention tank N, so that the water level in the retention tank N is lower than the water level in the tank. The edge of the mouth is not full. At this time, if there are residual water droplets in the first-level water vapor separation chamber K and drip into the second-level water vapor separation body, the water level in the retention tank N and the third guide pipe will rise accordingly. However, due to the viscosity of water, it will adhere to the side wall of the retention tank N, that is, the water in the retention tank N will not flow out. Therefore, no water droplets will drip from the water vapor separation outlet. In this way, the effect of quickly sealing water when stopping water intake is achieved, which effectively improves the problem of water leakage at the water intake of the water purifier.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The water purifier 100 of the embodiment of the present application is described below with reference to the accompanying drawings.

[0037] Figure 1 is a structural schematic diagram of the water purifier 100 provided in an embodiment of the present application; Figure 2 is a decomposition structural schematic diagram of the water purifier 100 provided in an embodiment of the present application; Figure 3 is a decomposition structural schematic diagram of the water purifier 100 provided in an embodiment of the present application from another angle, and Figure 4 is a cross-sectional view of the liquid level box 10 in the water purifier 100 provided in an embodiment of the present application.

[0038] 1 , 2 , and 3 , an embodiment of the present application provides a water purifier 100 for purifying water from a water source to be filtered.

[0039] The water purifier 100 includes a housing 80, a filter 40, a manifold 30, a clean water tank 20, a liquid level box 10, a water pump 50, a heater 55, and a water vapor separator 60. The filter 40 is in communication with the manifold cavity C of the manifold 30, which is in communication with the clean water tank 20 and the liquid level box 10, respectively. The water pump 50 is in communication with the manifold cavity C of the manifold 30 and the heater 55, respectively. This allows the water pump 50 to pump water from the liquid level box 10 and clean water tank 20 to the heater 55 via the manifold 30. The heater 55 is in communication with the water vapor separator 60. It should be noted that the manifold 30 and the clean water tank 20 are detachably connected.

[0040] With this arrangement, when a user draws water, the water pump 50 draws water from the communicating vessel 30 , and the water in the liquid level box 10 and the clean water tank 20 passes through the communicating vessel 30 at the same time and flows into the water pump 50 . The water in the water pump 50 flows into the heater 55 , and after being heated by the heater 55 , flows into the water vapor separator 60 and flows out of the water vapor separator 60 .

[0041] The filter 40 is connected to a water source to be purified to facilitate filtering the water source. The clean water tank 20 is used to store the filtered clean water. The liquid level box 10 is equipped with a water level sensor 12. The clean water tank 20 is connected to the liquid level box 10 through a communication vessel 30. Both the clean water tank 20 and the liquid level box 10 are open to the atmosphere. According to the communication vessel principle, the water level in the liquid level box 10 can reflect the water level in the clean water tank 20.

[0042] The heater 55 is used to heat the purified water, and the water vapor separator 60 is used to separate the water vapor in the heated purified water. The water vapor separator 60 is provided with a water vapor separation outlet 61, which forms the water inlet of the water purifier 100.

[0043] 2 and 3 , when the user needs to take clean water, the water pump 50 works, and the water in the clean water tank 20 and the liquid level box 10 is synchronously drawn into the heater 55 through the communicating vessel 30 . After passing through the heater 55 , the water continues to pass through the water vapor separator 60 and is taken out from the water vapor separation outlet 61 .

[0044] When the water level in the liquid level box 10 is lower than the high liquid level described below, the filter 40 works to purify the water source to be purified, and the purified water enters the liquid level box 10 and the clean water tank 20 respectively through the communicating vessel 30.

[0045] The various parts of the water purifier 100 will be described in detail below with reference to the accompanying drawings.

[0046] 1 and 2 , the interior of the housing 80 is hollow and includes a rear panel 870, a top cover 871, a base 872, and a front panel 873. The rear panel 870, the top cover 871, the base 872, and the front panel 873 collectively enclose a housing cavity, within which the filter 40, the communicating vessel 30, the liquid level box 10, the water pump 50, and the heater 55 are disposed. The rear panel 870 and the front panel 873 are disposed to the sides of the base 872 to form the main body of the housing 80, and the top cover 871 covers the front panel 873 and the rear panel 870. A bearing member 81 is further provided on the outer wall of the housing 80, and the clean water tank 20 is detachably mounted on the bearing member 81. The supporting member 81 is constructed as a water collecting box 85 , which is detachably arranged outside the shell 80 , and the top wall of the water collecting box 85 is provided with a water collecting hole 82 connected to the inside, and the clean water tank 20 is supported on the top wall of the water collecting box 85 .

[0047] Like this, clean water tank 20 is detachably arranged on the outside of housing 80, makes the user when needing a large amount of water, can directly unload clean water tank 20 and take water.In addition, can conveniently remove clean water tank 20, carry out maintenance operation such as cleaning.

[0048] In addition, referring to Figures 1 and 2 , a portion of the structure of the water vapor separator 60 passes through the housing 80 and extends outside the housing 80. The water vapor separation outlet 61 is located on the portion of the water vapor separator 60 that extends outside the housing 80. This facilitates the user to draw water from the water vapor separation outlet 61 outside the housing 80. For example, a relief opening 8731 can be formed on the front panel 873, through which the water vapor separation outlet 61 extends to the outside of the housing 80.

[0049] In the embodiment of the present application, referring to FIG4 , the water level sensor 12 is configured as a float sensor and includes a first float 121 and a second float 122. The liquid level box 10 is provided with a first upper baffle 123, a first lower baffle 124, a second upper baffle 125, and a second lower baffle 126 in order along the height direction of the liquid level box 10. The first float 121 is located between the first upper baffle 123 and the first lower baffle 124, and the second float 122 is located between the second upper baffle 125 and the second lower baffle 126. The water level sensor 12 is configured to detect the liquid level (also referred to as the water level when the liquid level box contains water) within the liquid level box 10. When the first float 121 abuts the first upper baffle 123, the liquid level is determined to be at a high level. When the second float 122 abuts the second lower baffle 126, the liquid level is determined to be at a low level. With this arrangement, the corresponding float stroke is relatively short regardless of whether it is detecting high or low liquid levels. Compared with the solution of setting only one float, it avoids the situation where the float has a long stroke at different liquid levels, which makes it easy for it to get stuck and cause inaccurate detection results or float failure.

[0050] In an embodiment of the present application, the water purifier 100 also includes a controller (not shown), which is electrically connected to the water level sensor 12 and the booster pump. The controller is configured to control the booster pump to stop working and thus stop water production when the liquid level in the liquid level box 10 is at a high liquid level; when the liquid level in the liquid level box 10 is lower than the high liquid level, control the booster pump to start working to produce water; when the liquid level in the liquid level box 10 is at a low liquid level, control the water pump 50 to stop working to stop water discharge.

[0051] In the embodiment of the present application, the water purifier 100 further includes an exhaust member 70. The exhaust member 70 is configured with a first chamber E connected to the atmosphere, and the first chamber E is connected to the filter liquid outlet of the filter 40 (not shown). As previously mentioned, the manifold 30 is configured with a manifold inner cavity C, and the manifold inner cavity C is respectively connected to the clean water tank 20, the liquid level box 10 and the first chamber E. Exemplarily, the water filtered by the filter 40 can be sequentially input into the exhaust member 70 and the manifold 30, and flow into the liquid level box 10 and the clean water tank 20 through the manifold inner cavity C. In addition, the manifold 30 is also connected to the filter liquid outlet on the filter body 43 described later and the water inlet of the water purifier.

[0052] By providing the exhaust component 70, the air in the communicating vessel 30 during the initial water production and the air entering the filter 40 can be discharged through the exhaust component 70. In other words, the water filtered out of the filter 40 is directly exhausted through the exhaust component 70, reducing the amount of gas entering the communicating vessel 30. This not only solves the problem of hot water jetting, but also solves the problem of unstable water shape and slow water outlet speed at the water inlet of the water purifier 100, and further facilitates the smooth flow of water.

[0053] Continuing with FIG3 , the liquid level box 10 is provided with an air outlet 13 communicating with the atmosphere; the exhaust member 70 is provided on the liquid level box 10, and the first chamber E is communicated with the liquid level box inner cavity A of the liquid level box 10 to communicate with the atmosphere through the air outlet 13. In this way, the liquid level box 10 and the exhaust member 70 can be integrally provided, which can reduce the number of parts and save installation steps.

[0054] Further, referring to Figure 5, the exhaust member 70 is provided on the outer side wall of the liquid level box 10. The exhaust member 70 and the side walls of the liquid level box 10 facing each other are provided with a communication port 14 that communicates with each other so that the first chamber E communicates with the liquid level box inner cavity A. The liquid level box 10 is communicated with the atmosphere through the first chamber E and the liquid level box inner cavity A, and thus the first chamber E of the exhaust member 70 communicates with the atmosphere through the liquid level box inner cavity A.

[0055] As for the communication mode between the various components, with reference to Figures 3, 4, and 5, for example, the exhaust member 70 may be provided with an exhaust member liquid inlet 72 and an exhaust member liquid outlet 73, the communicating vessel 30 may be provided with a communicating vessel liquid inlet 33 communicating with the communicating vessel inner cavity C, the exhaust member liquid inlet 72 is communicated with the filter liquid outlet via a first pipe 101, and the exhaust member liquid outlet 73 is communicated with the communicating vessel liquid inlet 33 of the communicating vessel 30 via a second pipe 102;

[0056] The heights of the vent 70 and the communication port 14 on the liquid level box 10 relative to the bottom wall of the liquid level box 10 are higher than the height of the vent liquid inlet 72. This prevents water that enters the vent 70 through the vent liquid inlet 72 from entering the liquid level box 10 through the communication port 14.

[0057] 3 , further, the communicating vessel liquid inlet 33 is connected to the filter liquid outlet of the filter 40 through the vent 70 , the communicating vessel liquid inlet 33 has a diameter greater than 6 mm, and the inner diameter of the second pipe 102 is greater than 6 mm.

[0058] When the diameter of the communicating vessel liquid inlet 33, or the inner diameter of the second pipe 102 connected to the communicating vessel liquid inlet 33 is less than 6 mm, the process of the air in the communicating vessel 30 entering the exhaust component 70 through the second pipe 102 is hindered, and poor exhaust is likely to occur, making it difficult for water to flow from the exhaust component 70 to the communicating vessel 30 stably and smoothly, resulting in the possibility that the accumulated water in the exhaust component 70 directly enters the liquid level box 10 from the communicating port 14, causing the water level in the liquid level box 10 to be too high, affecting the judgment of the water level in the clean water tank 20.

[0059] FIG6 is a schematic diagram of the structure of the filter 40 in the water purifier 100 provided in an embodiment of the present application. Referring to FIG6 , the filter 40 includes a filter housing 42 and a filter body 43. The filter housing 42 is configured with a filter cavity 44 with one end open (open to the atmosphere). The filter body 43 is disposed within the filter cavity 44. The air outlet 13 provided on the liquid level box 10 is in communication with the interior of the filter housing 42 of the filter 40.

[0060] The interior of the filter housing 42, i.e., the filter lumen 44, is in communication with the atmosphere, and the air outlet 13 is in communication with the interior of the filter housing 42 of the filter 40, thereby allowing the liquid level box 10 to communicate with the atmosphere. In addition, the clean water tank 20 is also in communication with the atmosphere. Therefore, when the water purifier 100 draws water from the liquid level box 10 and the clean water tank 20 through the communicating tube 30, or when water filtered by the filter 40 enters the liquid level box 10 and the clean water tank 20 through the communicating tube 30, according to the communicating tube principle, the water level in the liquid level box 10 and the clean water tank 20 can remain approximately equal, so that the water level in the liquid level box 10 can more accurately reflect the water level in the clean water tank 20. The liquid level box 10 (air outlet 13) is in communication with the interior of the filter 40 (i.e., the filter lumen 44 inside the filter housing 42) via the third pipe 103. Furthermore, the liquid level box 10 includes a box body 15 and a box cover 16 with a sealing cover disposed on the box body 15 , and the air outlet 13 is provided on the box cover 16 .

[0061] In specific implementation, as mentioned above, the filter housing 42 is provided with a filter housing air inlet 41 connected to the filter inner cavity, and both ends of the third pipe 103 are respectively connected to the air outlet 13 and the filter housing air inlet 41 to connect the liquid level box 10 with the atmosphere.

[0062] It can be understood that in order to access the filter body 43, the filter cavity must be provided with an opening, and the filter cavity is also connected to the atmosphere. By connecting the air outlet 13 of the liquid level box 10 with the filter cavity of the filter 40 through the third pipe 103, without adding a new opening on the shell 80 of the water purifier 100, the overall appearance of the water purifier 100 is more beautiful.

[0063] For example, a filter extension tube 421 is provided on the filter housing 42, communicating with the interior of the filter housing 42 through the filter housing air inlet 41. A liquid level box extension tube 161 is provided on the box cover 16 at a position corresponding to the air outlet 13. The ends of the third pipe 103 are respectively connected to the filter extension tube 421 and the liquid level box extension tube 161. This arrangement facilitates the connection of the ends of the third pipe 103 to the filter housing 42 and the liquid level box 10.

[0064] Furthermore, a first mounting portion 162 is provided on the box body 15, and a second mounting portion 422 is provided on the filter housing 42. The first mounting portion 162 is connected to the second mounting portion 422 to connect the liquid level box 10 to the filter 40. It is understandable that the number of the first mounting portion 162 and the second mounting portion 422 may also be multiple. For example, a portion of the first mounting portion 162 may also be provided on the box body 15, and the second mounting portion 422 corresponding to the portion of the first mounting portion 162 is provided at a position on the filter housing corresponding to the first mounting portion 162.

[0065] In addition, as mentioned above, the water pump 50 is connected to the communicating vessel 30 and the heater 55 respectively, and is used to pump water in the liquid level box 10 and the clean water tank 20 to the heater 55 through the communicating vessel 30 .

[0066] The steam separator 60 includes a steam separation outlet 62 and the aforementioned steam separation water outlet 61. The steam separation outlet 62 is communicated with the interior of the filter housing 42. In this way, the steam discharged from the steam separation outlet 62 can be discharged into the atmosphere through the filter housing 42.

[0067] In the embodiment of the present application, the filter 40 includes three stages of filtration to achieve a better filtering effect. In specific implementation, the filter body 43 includes a primary filter 431, a secondary filter 432, and a tertiary filter 433 connected in sequence. The filter cavity 44 includes a primary filter cavity 441, a secondary filter cavity 442, and a tertiary filter cavity 443 connected in sequence. The primary filter 431 is accommodated in the primary filter cavity 441, the secondary filter 432 is accommodated in the secondary filter cavity 442, and the tertiary filter 433 is accommodated in the tertiary filter cavity 443. The air outlet 13 is connected to the primary filter cavity 441. By configuring the filter body 43 to be a primary filter 431, a secondary filter 432, and a tertiary filter 433 connected in sequence, the filtering effect can be improved.

[0068] Furthermore, the water purifier 100 also includes a booster pump, which is used to pump water to be purified into the filter body 43, where the water source is purified. By providing a booster pump as a power source for the purifier to produce water, in addition to water sources with a certain water pressure such as tap water pipes, it can be applied to different types of water sources, such as water sources in water storage tanks in daily life. In the embodiment of the present application, in conjunction with Figures 3 and 4, as described above, the water pump 50 is respectively connected to the manifold 30 and the heater 55, and is used to pump water from the liquid level box 10 and the clean water tank 20 to the heater 55 through the manifold 30. The water vapor separator 60 is connected to the heater 55 and is used to separate water vapor from the water heated by the heater 55. With this arrangement, when a user draws water, the water pump 50 draws water from the communicating vessel 30 , and the water in the liquid level box 10 and the clean water tank 20 flows into the water pump 50 at the same time. The water in the water pump 50 flows into the heater 55 , and after passing through the heater 55 , flows into the water vapor separator 60 and flows out of the water vapor separator 60 .

[0069] Continuing to refer to Figure 6, further, the water vapor separation outlet 62 is connected to the third pipe 103 through the fourth pipe 104. In this way, the steam separated by the water vapor separation outlet 62 can also be discharged into the atmosphere through the filter housing 42. The number of pipes can also be reduced, making the structure more compact. As for the connection between the clean water tank 20 and the atmosphere, for example, referring to Figure 4, the clean water tank 20 includes a clean water tank body 25 and a water tank cover 26 that can be opened and closed on the clean water tank body 25. A gap is provided between the clean water tank body 25 and the water tank cover 26 to connect the clean water tank 20 to the atmosphere. In this way, when the user needs a large amount of water, he can open the water tank cover 26 and pour it out to take it.

[0070] Furthermore, the water vapor separation outlet 62 is provided at the top of the water vapor separator 60, and the third pipe 103 and the fourth pipe 104 are located on one side of the top of the liquid level box 10 and the water vapor separator 60. In this way, the lengths of the third pipe 103 and the fourth pipe 104 can be set shorter, and combined with the upward trend of water vapor, the water vapor can be discharged more smoothly.

[0071] Figure 7 is a schematic cross-sectional view of the water purifier 100 provided in an embodiment of the present application. In the embodiment of the present application, as described above, the communicating vessel 30 is connected to the liquid level box 10 and the clean water tank 20, respectively. In specific implementation, referring to Figures 3 and 7, the liquid level box 10 is provided with a liquid level box communication port 11, and the clean water tank 20 is provided with a clean water tank communication port 21. The communicating vessel 30 is also provided with a second communication port 31 and a first communication port 32; the second communication port 31 is connected to the liquid level box communication port 11, and the first communication port 32 is connected to the clean water tank communication port 21. In this way, the communicating vessel 30 is connected to the liquid level box 10 and the clean water tank 20, respectively. Further, referring to Figures 3 and 4, the communicating vessel 30 is also provided with a communicating vessel liquid outlet 38, which is connected to the water inlet of the water purifier 100; the setting height of the liquid level box communication port 11 relative to the bottom of the water purifier 100 is higher than the setting height of the communicating vessel liquid outlet 38. With this arrangement, the liquid in the level box 10 can flow out of the manifold 30 relatively smoothly through the manifold outlet 38, thereby avoiding a situation where the liquid level box 10 is blocked from flowing out, causing water to accumulate in the level box 10, resulting in the clean water provided to the water intake being mixed with the accumulated water. Specifically, an extension tube 39 is provided on the manifold 30. The extension tube 39 extends from the outside (e.g., the top) of the manifold 30 through the wall of the manifold 30 and to the bottom of the manifold inner cavity C. The end of the extension tube 39 located within the manifold inner cavity C forms the manifold outlet 38.

[0072] Of course, the connection between the water pump 50 and the manifold 30 is achieved by connecting the manifold outlet 38 to the inlet of the water pump 50 through a pipe. The outlet of the water pump 50 is also connected to the heater 55 through another pipe to transport the clean water in the manifold 30 to the heater 55. The water pump 50 can be connected to the outer wall of the exhaust member 70 by fasteners such as screws.

[0073] Furthermore, the height of the manifold inlet 33 relative to the bottom of the water purifier 100 is higher than the heights of the liquid level box communication port 11, the clean water tank communication port 21, and the manifold outlet 38. The manifold inlet 33 can be located at the very top of the manifold 30. This allows the purified water entering the manifold 30 through the manifold inlet 33 to flow smoothly into the liquid level box 10 and the clean water tank 20.

[0074] FIG8 is a schematic diagram of another structure of the manifold 30 in the water purifier 100 provided in an embodiment of the present application. Referring to FIG8 , since the water production and water intake of the water purifier 100 must pass through the manifold 30, during the water production process, due to the small volume of the manifold 30, air cannot be discharged smoothly. It can be considered to connect the manifold inner cavity C with the filter liquid outlet of the filter 40. For example, the filter liquid outlet of the filter 40 can be connected to the manifold liquid inlet 33 through a pipe (not shown). At this time, the manifold liquid inlet 33 can be connected to the exhaust member 70 at the same time, or only connected to the filter liquid outlet, and not connected to the exhaust member 70. Furthermore, an exhaust portion 701 connected to the atmosphere is provided on the manifold 30, and the exhaust portion 701 is connected to the manifold inner cavity C, thereby facilitating the air to be discharged smoothly from the manifold 30 during the water production and water intake process of the water purifier 100, so that the water flow is smooth, so that the water levels of the clean water tank 20 and the float box can be in a balanced state in real time. When the manifold liquid inlet 33 is connected only to the filter liquid outlet but not to the exhaust member 70, water filtered by the filter 40 does not pass through the exhaust member 70 but instead enters the manifold inner cavity C directly from the manifold liquid inlet 33 and is exhausted by the exhaust portion 701. Specifically, the manifold 30 is provided with an exhaust port 301 at the top thereof, which is connected to the manifold inner cavity C. The exhaust port 301 forms the exhaust portion 701. Of course, to facilitate the smooth exhaust of air within the manifold 30, an exhaust pipe 302 is also provided on the exhaust port 301, which extends along the height of the water purifier 100.

[0075] It should be noted that, in another possible embodiment, the liquid inlet 33 of the communicating vessel can be simultaneously connected to the liquid outlet of the filter of the exhaust component 70. The water in the filter 40 can partially enter the communicating vessel 30 through the exhaust component 70, or can partially enter the communicating vessel 30 directly through the pipe connected to the liquid inlet 33 of the communicating vessel. At this time, exhaust can be carried out simultaneously through both the exhaust component 70 and the exhaust part 701.

[0076] The working process of the water purifier 100 according to the embodiment of the present application will be described below with reference to FIG3 and FIG7 . When the user needs to take clean water, as shown by the dotted arrow in Figure 3, the water pump 50 works, and the clean water in the clean water tank 20 enters the inner cavity C of the communicating vessel through the clean water tank connecting port 21 and the first connecting port 32. The clean water in the liquid level box 10 enters the inner cavity C of the communicating vessel through the liquid level box connecting port 11 and the second connecting port 31. Driven by the water pump 50, the clean water in the inner cavity C of the communicating vessel enters the water pump 50 through the liquid outlet 38 of the communicating vessel and enters the heater 55 connected to the water pump 50. When the clean water enters the heater 55, the heater 55 works to heat the clean water. If the heater 55 does not work, the clean water will not be heated. The water entering the heater 55 eventually enters the water vapor separator 60. After the heated clean water is separated from the water vapor by the water vapor separator 60, the clean water flows out from the water vapor separation outlet 61. If the clean water is not heated in the heater 55, it also flows out directly through the water vapor separation outlet 61. In this process, the water pump 50 serves as a driving source for the entire cycle.

[0077] During the water production process, as indicated by the solid arrows in Figures 3 and 4 , the booster pump (not shown) operates, the filter 40 purifies the water source to be purified, and the purified water is transported through the first pipe 101 to the first chamber E of the exhaust member 70. The purified water then enters the inner cavity C of the manifold through the exhaust member liquid outlet 73, the second pipe 102, and the manifold liquid inlet 33. A portion of the purified water entering the inner cavity C of the manifold enters the clean water tank 20 through the first connecting port 32 and the clean water tank connecting port 21, while the remaining portion enters the liquid level box 10 through the second connecting port 31 and the liquid level box connecting port 11. Specifically, during the water production process, when the water level in the liquid level box 10 falls below the high liquid level, the filter 40 operates to purify the water source to be purified. The purified water then enters the liquid level box 10 and the clean water tank 20, respectively, through the aforementioned process. During this process, the booster pump serves as the driving source for the entire cycle.

[0078] 3 and 7 , the volume of the clean water tank cavity B of the clean water tank 20 is greater than the volume of the liquid level box cavity A of the liquid level box 10. As previously mentioned, the water filtered by the filter 40 can flow into the liquid level box 10 and the clean water tank 20 through the inner cavity C of the communicating vessel.

[0079] 4 and FIG. 9 described later, the minimum cross-sectional area of ​​the first connecting channel P connecting the clean water tank connecting port 21 with the inner cavity C of the communicating vessel is greater than the minimum cross-sectional area of ​​the second connecting channel Q connecting the liquid level box connecting port 11 with the inner cavity C of the communicating vessel.

[0080] Since the volume of the clean water tank cavity B of the clean water tank 20 is larger than the volume of the liquid level box cavity A of the liquid level box 10, if the water inlet and outlet speeds of the clean water tank 20 are the same as those of the liquid level box 10, it is easy for the liquid level in the clean water tank 20 to temporarily be higher than that of the liquid level box 10 when the water purifier 100 is in use. In the present application, by making the minimum cross-sectional area of ​​the first channel P larger than the minimum cross-sectional area of ​​the second channel Q, the water inlet and outlet volume per unit time of the clean water tank 20 is greater than that of the liquid level box 10. That is, the water outlet speed of the larger clean water tank 20 is greater than that of the smaller liquid level box 10. This can compensate for the temporary liquid level difference caused by the volume difference between the two. When the water purifier 100 is in use, the liquid levels of the clean water tank 20 and the liquid level box 10 remain consistent in real time, so that the water level detected by the water level detector in the liquid level box 10 can always truly reflect the water level in the clean water tank 20, avoiding the occurrence of reverse water leakage.

[0081] Furthermore, the communicating vessel 30 is provided with a communicating vessel connecting pipe 34 communicating with the communicating vessel inner cavity C. The communicating vessel connecting pipe 34 is provided at a position corresponding to that of the first communicating port 32 .

[0082] The clean water tank 20 is provided with a clean water tank connecting pipe 22, which corresponds to the location of the clean water tank communication port 21 and communicates with the clean water tank inner cavity B of the clean water tank 20. When supported on the support member 81, the clean water tank connecting pipe 22 is configured to be partially inserted into the manifold connecting pipe 34, thereby connecting the manifold inner cavity C with the clean water tank inner cavity B. The portion of the manifold connecting pipe 34 not connected to the clean water tank connecting pipe 22 and the clean water tank connecting pipe 22 together define a first communication passage P. The cross-sectional area of ​​the first communication passage P is minimized at the portion of the manifold connecting pipe 34 not connected to the clean water tank connecting pipe 22.

[0083] Furthermore, the manifold 30 is provided with a manifold inserting tube 341 that communicates with the manifold inner cavity C. Manifold inserting tube 341 corresponds to the location of the second communication port 31. The liquid level box 10 is provided with a liquid level box inserting tube 17 that communicates with the liquid level box inner cavity A. This inserting tube 17 plugs into the manifold inserting tube 341. The portion of manifold inserting tube 341 not connected to the liquid level box inserting tube 17 together with the liquid level box inserting tube 17 defines a second communication channel Q. The smallest cross-sectional area of ​​the second communication channel Q is located within the liquid level box inserting tube 17.

[0084] In the embodiment of the present application, the cross-sectional area S1 of the inner cavity B of the water purification tank along the height direction of the water purifier 100, the minimum cross-sectional area S2 of the first communication channel P, the cross-sectional area S3 of the inner cavity A of the liquid level box along the height direction of the water purifier 100, and the minimum cross-sectional area S4 of the second communication channel Q meet the following requirements:

[0085] S3 / S4=K*S1 / S2, where K is the resistance coefficient of the fluid in the liquid level box communication port 11, and the cross-section of the water purification tank inner cavity B and the cross-section of the liquid level box inner cavity A remain unchanged along the height direction of the water purifier 100.

[0086] In addition, the value of the fluid resistance coefficient K will change with the depth or shape of the hole at the communication port 11 of the liquid level box.

[0087] In this way, when the water purifier 100 is in use, the liquid levels in the clean water tank 20 and the liquid level box 10 can always remain completely consistent, so that the water level detected by the water level detector in the liquid level box 10 can reflect the actual water level in the clean water tank 20 in real time, avoiding the occurrence of reverse water duplication.

[0088] Furthermore, the cross-sectional area S1 of the clean water tank cavity B along the height of the water purifier 100 and the cross-sectional area S3 of the liquid level box cavity A along the height of the water purifier 100 satisfy the following relationship: S1>S3; the bottom wall of the clean water tank cavity B is flush with the bottom wall of the liquid level box cavity A. In this way, the water level detected by the water level detector in the liquid level box 10 can be the actual water level in the clean water tank 20.

[0089] Furthermore, the cross-sectional area of ​​the first communication port 32 is greater than the cross-sectional area of ​​the second communication port 31. Furthermore, the cross-sectional area of ​​the liquid level box communication port 11 is greater than or equal to 4.5 mm 2 And / or the cross-sectional area of ​​the clean water tank communication port 21 is greater than 40mm 2 .

[0090] If the cross-sectional area of ​​the liquid level box communication port 11 is too large, that is, the diameter of the liquid level box communication port 11 is too large, the water flow rate in the liquid level box 10 is relatively fast, causing the water level in the liquid level box 10 to drop too quickly, resulting in the liquid in the liquid level box 10 dropping too quickly and the liquid level being lower than the clean water tank 20. As a result, the water level detected by the water level detector cannot reflect the actual water level in the clean water tank 20. When the cross-sectional area of ​​the liquid level box communication port 11 is too small, that is, the diameter of the liquid level box communication port 11 is too small, the water flow rate in the liquid level box 10 is relatively slow, causing the water level in the liquid level box 10 to drop too slowly. Similarly, the water level detected by the water level detector cannot reflect the actual water level in the clean water tank 20.

[0091] When the cross-sectional area of ​​the liquid level box communication port 11 is greater than or equal to 4.5 mm 2 , and / or the cross-sectional area of ​​the clean water tank communication port 21 is greater than 40mm 2 At this time, it can be ensured that the water in the liquid level box 10 enters and exits the communicating vessel 30 through the liquid level box connecting port 11, and when the water in the clean water tank 20 enters and exits the communicating vessel 30 through the clean water tank connecting port 21, the rise and fall of the water level in the liquid level box 10 and the rise and fall of the water level in the clean water tank 20 are carried out synchronously, so that the water level detection result in the liquid level box 10 detected by the water level detector can more accurately reflect the water level in the clean water tank 20.

[0092] Figure 9 is a schematic diagram showing the result of the cooperation between the first communication port 32 and the clean water tank communication port 21 in the water purifier 100 provided in the embodiment of the present application. In the embodiment of the present application, as mentioned above, a bearing member 81 is further provided on the outer wall of the housing 80, and the clean water tank 20 is detachably mounted on the bearing member 81.

[0093] 3 , 8 , and 9 , to connect the clean water tank 20 with the manifold 30, the first communication port 32 and the clean water tank communication port 21 are respectively provided with a manifold check valve 36 and a clean water tank check valve 27. Furthermore, as previously described, the manifold 30 is provided with a manifold connecting pipe 34 communicating with the manifold inner cavity C. The manifold connecting pipe 34 is disposed at a position corresponding to the first communication port 32. In a specific implementation, at least a portion of the manifold 30 is disposed within the housing 80. The manifold connecting pipe 34 extends from the interior of the housing 80 to the exterior of the housing 80 and extends to the load-bearing side of the carrier 81.

[0094] In this way, most of the communicating vessel 30 is accommodated in the shell 80, and only the communicating vessel connecting pipe 34 for connecting to the water purifier 100 is extended out of the shell 80. The clean water tank 20 can be placed on the supporting member 81 outside the shell 80 for easy access by the user.

[0095] Correspondingly, the clean water tank 20 is provided with a clean water tank connecting pipe 22, which is in communication with the clean water tank inner cavity B of the clean water tank 20 and is arranged at a position corresponding to the clean water tank communication port 21. The manifold check valve 36 is located in the manifold connecting pipe 34, and the clean water tank check valve 27 is arranged in the clean water tank connecting pipe 22.

[0096] The clean water tank connecting pipe 22 is configured to be able to be inserted into the communicating vessel connecting pipe 34 when it is carried on the supporting member 81 to connect the communicating vessel inner cavity C and the clean water tank inner cavity B. For example, when the clean water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the clean water tank check valve 27 pushes open the valve core 361 of the communicating vessel check valve to realize the water inlet and outlet of the communicating vessel 30 and the clean water tank 20.

[0097] More specifically, referring to Figures 3 and 8 , a valve seat 362 is provided in the communicating vessel connecting pipe 34. The valve core 361 of the communicating vessel check valve is elastically connected to the valve seat 362, for example, by an elastic member. When the clean water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the valve core 271 of the clean water tank check valve overcomes the elastic force of the elastic member and presses against the valve core 361 of the communicating vessel check valve to open the communicating vessel check valve 36. At the same time, the valve core 361 of the communicating vessel check valve also pushes open the valve core 271 of the clean water tank check valve to open the clean water tank check valve 27. When the clean water tank connecting pipe 22 is separated from the communicating vessel connecting pipe 34, the valve core 361 of the communicating vessel check valve returns to its original state under the action of the elastic member (not shown), closing the communicating vessel connecting pipe 34. Of course, when the clean water tank connecting pipe 22 is disconnected from the manifold connecting pipe 34, the valve core 271 of the clean water tank check valve also returns to its original state under the action of the elastic member, closing the clean water tank connecting pipe 22. For example, the cross-sectional area of ​​the valve core 361 of the manifold check valve is less than or equal to the cross-sectional area of ​​the valve core 271 of the clean water tank check valve. This allows the clean water tank connecting pipe 22 to be inserted into the manifold connecting pipe 34, and the valve core 271 of the clean water tank check valve can reliably press against the valve core 361 of the manifold check valve, smoothly opening the manifold check valve 36 and enabling water to flow in and out of the manifold 30 to the clean water tank 20.

[0098] Figure 10 is a schematic cross-sectional view of the structure in which the first communication port 32 and the clean water tank communication port 21 are separated in the water purifier 100 provided in an embodiment of the present application; Figure 11 is a partial enlarged view of the U portion of Figure 10; Figure 12 is a schematic cross-sectional view of the structure in which the first communication port 32 and the clean water tank communication port 21 are matched in the water purifier 100 provided in an embodiment of the present application; Figure 13 is a partial enlarged view of the V portion of Figure 12. Figure 14 is a schematic view of the structure in which the sealing ring 35 and the communicating vessel connecting pipe 34 are matched in the water purifier 100 provided in an embodiment of the present application. It should be noted that in Figures 12 and 13, the structure of the clean water tank check valve 27 is omitted for ease of observation.

[0099] In the embodiment of the present application, referring to Figures 9, 10, 11, 12 and 13, a sealing ring 35 is provided on the inner wall of the communicating vessel connecting pipe 34, and the axial ends of the sealing ring 35 abut against the inner wall of the communicating vessel connecting pipe 34. The first sealing section 353 between the axial ends of the sealing ring 35 and the inner wall of the communicating vessel connecting pipe 34 jointly define a water storage chamber F; the clean water tank connecting pipe 22 is configured to be inserted into the communicating vessel connecting pipe 34 when it is carried on the supporting member 81 so that the communicating vessel inner cavity C and the clean water tank inner cavity B are connected; and the first sealing section 353 is elastically deformed toward its own radial outside to squeeze the water in the water storage chamber F into the communicating vessel connecting pipe 34; and when it is separated from the communicating vessel connecting pipe 34, the first sealing section 353 is elastically reset toward its own radial inside to absorb the water in the communicating vessel connecting pipe 34 into the water storage chamber F.

[0100] In the above embodiment, the first sealing section 353 between the axial ends of the sealing ring 35 and the inner wall of the manifold connecting pipe 34 jointly define a water storage chamber F. This water storage chamber F has a certain water storage capacity. Because the clean water tank connecting pipe 22 can elastically return radially inward when it is separated from the manifold connecting pipe 34, the first sealing section 353 is attracted to the water storage chamber F. Therefore, when the clean water tank 20 is removed by the user and the clean water tank connecting pipe 22 is separated from the manifold connecting pipe 34, even if there is water in the manifold 30 that flows into the manifold connecting pipe 34, it will be partially or completely absorbed by the water storage chamber F, thereby alleviating the problem of some water flowing into the manifold connecting pipe 34 due to the momentary separation of the clean water tank connecting pipe 22 and the manifold connecting pipe 34 when the clean water tank 20 is removed.

[0101] Continuing with reference to Figures 11 and 13, further, of the two axial ends of the sealing ring 35, the end facing the clean water tank 20 is defined as the first end 351, and the end away from the clean water tank 20 is defined as the second end 352; the first end 351 is provided with an annular flange portion 3511, and the flange portion 3511 and the outer peripheral surface of the sealing ring 35 define a flange portion mounting groove G, and the end of the communicating vessel connecting pipe 34 facing the clean water tank 20 is snapped into the flange portion mounting groove G, so that the partial structure of the first end 351 abuts against the inner wall of the communicating vessel connecting pipe 34.

[0102] In this way, the first end 351 of the sealing ring 35 covers the end of the communicating tube 34 facing the clean water tank 20, thereby preventing the water in the water storage chamber F from leaking from the first end 351, that is, the side facing the clean water tank 20.

[0103] Furthermore, the second end portion 352 is provided with an annular protrusion 3521, which abuts against the inner wall of the communicating tube 34. The protrusion 3521, the outer peripheral surface of the first sealing section 353 and the flange portion 3511 jointly define a water storage groove, and the water storage groove and the inner wall of the communicating tube 34 jointly define a water storage chamber F.

[0104] Thus, by providing a water-retaining groove on the sealing ring 35 to form the water-retaining chamber F, the structure is relatively simple and easy to manufacture. Furthermore, the clean water tank connecting pipe 22 is easily inserted into the inner side of the sealing ring 35, pressing the inner circumference of the sealing ring 35 radially outward, causing the first sealing section 353 to elastically deform radially outward, thereby squeezing the water in the water-retaining chamber F into the communicating vessel connecting pipe 34.

[0105] In the embodiment of the present application, referring to Figure 11 , the inner circumferential surface of the first sealing section 353 is protrudingly provided with at least two annular interference fit portions 3531 , at least two interference fit portions 3531 are arranged at axial intervals along the sealing ring 35 , and at least two interference fit portions 3531 are used for interference fit with the clean water tank connecting pipe 22 .

[0106] In this way, when the clean water tank connecting pipe 22 is inserted into the manifold connecting pipe 34, it can be sealed with the sealing ring 35 to prevent water from leaking between the clean water tank connecting pipe 22 and the manifold connecting pipe 34. For example, the protrusion height of the interference fit portion 3531 from the inner circumferential surface of the sealing ring 35 gradually decreases along the direction from the first end 351 to the second end 352.

[0107] Along the direction from the first end 351 to the second end 352, that is, the direction in which the clean water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, during the above-mentioned insertion process, the clean water tank connecting pipe 22 first contacts the interference fit portion 3531 with a higher protrusion height, which can quickly seal the water and avoid water leakage. Continuing to insert, the clean water tank connecting pipe 22 cooperates with the interference fit portion 3531 with a lower protrusion height, and the interference is relatively small, which can reduce the difficulty of inserting the clean water tank connecting pipe 22 and increase the insertion feel. In the embodiment of the present application, referring to Figure 14, there are two interference fit portions 3531, and a support protrusion 354 is provided on the outer peripheral surface of the sealing ring 35 between the areas corresponding to the two interference fit portions 3531. In this way, when the clean water tank connecting pipe 22 is inserted into the inner side of the sealing ring 35, the interference fit portion 3531 elastically deforms toward the inner wall of the communicating vessel connecting pipe 34 under the pressure of the clean water tank connecting pipe 22, and the support protrusion 354 first contacts the inner wall of the communicating vessel connecting pipe 34. At this time, on the outer peripheral surface of the sealing ring 35, the areas corresponding to the two interference fit portions 3531 will form two avoidance spaces with the inner wall of the communicating vessel connecting pipe 34. The existence of the two avoidance spaces allows the two interference fit portions 3531 to still have room for elastic deformation radially outward or radially inward, thereby preventing the clean water tank connecting pipe 22 from being incompatible with the sealing ring 35 due to dimensional tolerance, etc., and can also solve the problem of poor hand feel during the insertion process of the clean water tank connecting pipe 22. Furthermore, there are two interference fit portions 3531. On the outer circumference of the sealing ring 35, areas corresponding to the two interference fit portions 3531 are each provided with an escape groove H. The escape groove H corresponding to the interference fit portion 3531 with a higher protrusion is deeper than the escape groove H corresponding to the interference fit portion 3531 with a lower protrusion. This ensures that the higher-protruding interference fit portion 3531 has a larger escape space, while the lower-protruding interference fit portion 3531 has a smaller escape space. This differentiated design maximizes the capacity of the water storage chamber F.

[0108] 3 , 9 , and 13 , when the clean water tank connecting pipe 22 of the clean water tank 20 is inserted into the manifold connecting pipe 34, the valve core 271 of the clean water tank check valve presses against the valve core 361 of the manifold check valve, opening the manifold check valve 36 and establishing communication between the clean water tank cavity B of the clean water tank 20 and the manifold cavity C of the manifold 30. At this point, the clean water tank connecting pipe 22 is inserted into the inner side of the sealing ring 35 and pushes the first sealing section 353 radially outward of the sealing ring 35, causing the outer wall of the first sealing section 353 to press against the inner wall of the manifold connecting pipe 34, thereby flattening the water storage cavity F. When the clean water tank connecting pipe 22 is drawn out from the communicating vessel connecting pipe 34, some water flows out from the valve core 361 of the communicating vessel check valve. At this time, the squeezing of the first sealing section 353 by the communicating vessel connecting pipe 34 disappears, the sealing ring 35 is restored, and the water storage chamber F returns to its original state. The water that has flowed out into the communicating vessel connecting pipe 34 will be squeezed into the water storage chamber F due to the action of atmospheric pressure and temporarily stored in the water storage chamber F.

[0109] FIG15 is a schematic structural diagram of the connection between the carrier 81 and the shell 80 in the water purifier 100 provided in an embodiment of the present application.

[0110] In the embodiment of the present application, referring to Figure 15, as described above, the supporting member 81 is detachably connected to the shell 80, for example, connected to the front panel 873. The supporting member 81 is constructed with a water collecting chamber D, and the top wall of the supporting member 81 is provided with a water collecting hole 82 connected to the water collecting chamber D. The clean water tank 20 is supported on the top wall of the supporting member 81. In this way, water leaking from the connection between the clean water tank 20 and the communicating vessel 30 can enter the water collecting chamber D through the water collecting hole 82. Alternatively, the user can also place a water cup on the supporting member 81, and the water outside the water cup and the outside of the clean water tank 20 can also be poured into the water collecting chamber D through the water collecting hole 82. Furthermore, the outer wall of the shell 80 is provided with a water guide portion 83, and the supporting member 81 is detachably connected to the shell 80 by plugging and fitting with the water guide portion 83. The water guide portion 83 has a guide surface 831 . A guide hole 832 communicating with the water collecting chamber D is defined on the guide surface 831 . The guide surface 831 is configured to guide water in the communicating vessel connecting pipe 34 to the guide hole 832 .

[0111] 15 , the water in the communicating vessel connecting pipe 34 can be guided to the guide hole 832 by the guide portion and finally flow into the water collecting chamber D. The user can remove the carrier 81 periodically and clean the water in the water collecting chamber D.

[0112] Furthermore, to better guide water flowing out of the manifold connecting pipe 34, the projection of the end of the manifold connecting pipe 34 facing the clean water tank 20 on a first plane is within the projection of the guide surface 831 on the first plane, where the first plane is perpendicular to the height direction of the water purifier 100. This allows water to leak from the end of the manifold connecting pipe 34 and fall under gravity, which in turn allows it to be completely caught by the guide surface 831 and collected in the water collection chamber D. In a specific implementation, the guide surface 831 is constructed as a conical surface centered on the guide hole 832. This inclined conical surface provides better water guidance.

[0113] Furthermore, the shell 80 is provided with a through hole 8733 for the communicating vessel connecting pipe 34 to pass through; the communicating vessel 30 also includes a pressure cap 37, which is connected to the edge of the hole 8733, and the pressure cap 37 is provided with a pressure cap opening 371 for the clean water tank connecting pipe 22 to be inserted into the communicating vessel connecting pipe 34, and the pressure cap 37 presses the end of the sealing ring 35 facing the clean water tank 20 onto the communicating vessel connecting pipe 34.

[0114] In this way, the sealing ring 35 can be fixed more reliably on the communicating vessel connecting pipe 34. For example, the end of the pressure cover 37 is provided with a bent portion bent inwardly, and the top end of the bent portion is pressed tightly on the sealing ring 35.

[0115] Correspondingly, referring to Figure 10 , the outer wall of the clean water tank 20 is constructed with a clean water tank installation groove 28. The clean water tank connecting pipe 22 is disposed on the bottom wall of the clean water tank installation groove 28. An accommodating space I is defined between the outer wall of the clean water tank connecting pipe 22 and the side wall of the clean water tank installation groove 28. The accommodating space I is used to accommodate the gland 37. This makes the surface of the clean water tank 20 relatively flat and the structure more beautiful.

[0116] In the embodiment of the present application, in conjunction with Figures 2 and 15, in order to detect whether the clean water tank 20 is located on the support member 81, the water purifier 100 also includes a sensor assembly 86. The sensor assembly 86 is disposed within the housing 80 and is configured to detect the relative position of the clean water tank 20 and the support member 81. Regarding the location of the sensor assembly 86, for example, it can be disposed inside the housing 80, so that the detection end of the sensor assembly 86 extends from the inside of the housing 80 to the outside of the housing 80 and extends to the support side of the support member 81. Of course, in order to trigger the sensor assembly 86, a trigger portion 861 is provided on the outer wall of the clean water tank 20 at a position corresponding to the detection end; the trigger portion 861 is configured to contact the detection end when the clean water tank 20 is supported on the support member 81, triggering the sensor assembly 86 to perform detection. In this way, it is convenient to determine whether the clean water tank 20 is located on the support member 81.

[0117] In a specific implementation, the sensor assembly 86 can be, for example, a micro switch. When the clean water tank 20 is placed on the carrier 81, the trigger part 861 triggers the detection end of the sensor assembly 86 to detect that the clean water tank 20 is in place.

[0118] Figure 16 is a cross-sectional view of the water purification tank 20 in the water purifier 100 provided in an embodiment of the present application, Figure 17 is a cross-sectional view of the water purification tank 20 in the water purifier 100 provided in an embodiment of the present application from another angle, Figure 18 is a partial enlarged view at X in Figure 17, and Figure 19 is a schematic diagram of the decomposed structure of the sterilization unit 90 in the water purifier 100 provided in an embodiment of the present application.

[0119] 16, 17, 18, and 19, in the embodiment of the present application, the water purifier 100 further includes a sterilization unit 90 for sterilizing and disinfecting the purified water retained in the purified water tank 20. Specifically, referring to FIG10 and FIG17, the purified water tank 20 further includes a first mounting groove 29, and a first mounting opening 291 is provided on the bottom wall of the first mounting groove 29. 18 and 19 , the sterilization unit 90 includes a lampshade 91, a lampshade positioning assembly 92, and a germicidal lamp 96. The lampshade positioning assembly 92 includes an annular first positioning member 93, a first sealing ring 94, and a second sealing ring 95. The lampshade 91 is positioned within the first mounting groove 29, with the head of the lampshade 91 exposed to the clean water tank 20 through the first mounting opening 291. The first positioning member 93 is sleeved around the outer periphery of the lampshade 91. The first sealing ring 94 is sealingly disposed between the first positioning member 93 and the side wall of the first mounting groove 29, and the second sealing ring 95 is sealingly disposed between the first positioning member 93 and the outer periphery of the lampshade 91. In a specific implementation, for example, the first sealing ring 94 is interference-fitted between the first positioning member 93 and the side wall of the first mounting groove 29, and the second sealing ring 95 is interference-fitted between the first positioning member 93 and the outer periphery of the lampshade 91. The germicidal lamp 96 is disposed on the outer wall of the housing 80 . When the clean water tank 20 is supported on the supporting member 81 , the germicidal lamp 96 can extend into the inner side of the lampshade 91 .

[0120] In the above solution, the clean water tank 20 is detachably mounted on the support 81 on the outer wall of the housing 80, and the user can take the clean water tank 20 at any time as needed. The first positioning member 93 is sleeved on the outer peripheral side of the lampshade 91, the first sealing ring 94 is sealed between the first positioning member 93 and the side groove wall of the first mounting groove 29, and the second sealing ring 95 is sealed between the first positioning member 93 and the outer peripheral side of the lampshade 91. In this way, the lampshade 91 can be installed in the first mounting groove 29. Since the head of the lampshade 91 is exposed to the clean water tank 20 through the first mounting opening 291, and the sterilizing lamp 96 extends into the inner side of the lampshade 91 when the clean water tank 20 is supported on the support 81, when the clean water tank 20 is supported on the support 81, the light emitted by the sterilizing lamp 96 located inside the lampshade 91 passes through the lampshade 91 and irradiates the clean water tank 20 to sterilize the water stored in the clean water tank 20.

[0121] In addition, the lampshade positioning assembly 92 includes a first positioning member 93, a first sealing ring 94 and a second sealing ring 95 respectively arranged on the outside and inside of the first positioning member 93. The first positioning member 93 serves as a supporting frame, and the first sealing ring 94 and the second sealing ring 95 mainly play a deformation sealing role. Compared with the related art that only uses a sealing ring 35 and the radial thickness of the entire sealing ring 35 is large, the radial thickness of the deformed first sealing ring 94 and the second sealing ring 95 is small, and the degree and speed of aging will be slowed down, thereby improving the reliability of the seal. As the use time increases, the possibility of water leakage is smaller. For example, the lampshade 91 is a light-transmitting structure. For example, the head of the lampshade 91 can be extended into the clean water tank 20 through the first mounting port 291 to allow the germicidal lamp 96 to irradiate as much water as possible. The germicidal lamp 96 can be, for example, an ultraviolet germicidal lamp.

[0122] In a specific implementation, the hardness of the first positioning member 93 is greater than the hardness of the first sealing ring 94 and the second sealing ring 95. In this way, the aging speed of the lampshade 91 installation assembly can be further reduced. And the overall strength of the lampshade 91 installation assembly can be improved. For example, the first positioning member 93 can be set as a metal member, and the first sealing ring 94 and the second sealing ring 95 can be set as rubber members. Of course, in order to increase the sealing performance, the number of first sealing rings 94 is at least two, and at least two first sealing rings 94 are arranged along the axial direction of the first positioning member 93. Similarly, the number of second sealing rings 95 is at least two, and at least two second sealing rings 95 are arranged along the axial direction of the first positioning member 93. In this way, multiple lines of defense are arranged in the axial direction of the first positioning member 93, which can minimize the occurrence of water leakage.

[0123] Continuing with reference to FIG19 , when there are multiple first sealing rings 94 and second sealing rings 95, in order to position them in the axial direction, it can be considered to provide at least one annular second mounting groove 932 on the outer circumference of the first positioning member 93, and the first sealing ring 94 is installed in the second mounting groove 932 in a one-to-one correspondence. In this way, the first sealing ring 94 can be prevented from moving in the axial direction of the first positioning member 93. The inner circumference of the first positioning member 93 is provided with at least one annular stopper 931. The stopper 931 and the inner circumference of the first positioning member 93 define a half-open annular mounting space J, and the second sealing ring 95 is installed in the annular mounting space J. In this way, the stopper 931 and the sealing member 97 together form an installation space for installing the second sealing ring 95.

[0124] In the embodiment of the present application, in conjunction with Figures 18 and 19, the lampshade positioning assembly 92 also includes a sealing member 97, which is connected to the end of the first positioning member 93 facing the clean water tank 20 and is blocked on the side of the second sealing ring 95 facing the clean water tank 20. In this way, the second sealing ring 95 is prevented from detaching from the gap between the first positioning member 93 and the lampshade 91. As for the connection method between the sealing member 97 and the first positioning member 93, for example, the sealing member 97 can be provided with a clamping arm 973, and the first positioning member 93 can be provided with a clamping groove 974, and the sealing member 97 and the first positioning member 93 are connected by the clamping fit of the clamping arm 973 and the clamping groove 974. In this way, the first positioning member 93 and the sealing member 97 can be reliably connected as a whole. Furthermore, the sealing member 97 is provided with an annular first abutting portion 971 and a second abutting portion 972 at the axial end of the first positioning member 93. The first abutting portion 971 is configured to abut the second sealing ring 95, and the second abutting portion 972 is configured to abut the end of the lampshade 91 facing the purified water tank 20. This prevents the second sealing ring 95 from moving axially in the first positioning member 93 and prevents the lampshade 91 from being separated from the first mounting groove 29.

[0125] Continuing with Figure 18 , the germicidal lamp 96 includes a lamp mounting bracket 961 and a lamp body 962. The lamp mounting bracket 961 is mounted on the outer wall of the housing 80 at a position corresponding to the first mounting opening 291, while the lamp body 962 is mounted on the end of the lamp mounting bracket 961 facing the clean water tank 20. This allows the germicidal lamp 96 to be installed in a position corresponding to the lampshade 91. Of course, a second mounting opening 8732 is provided on the housing 80, allowing the lamp mounting bracket 961 to pass through the second mounting opening 8732 and extend outside the housing 80. Continuing with Figure 17 , the first mounting opening 291 and the clean water tank connection opening 21 are both located between the top and bottom of the clean water tank 20, with the first mounting opening 291 positioned higher than the clean water tank connection opening 21. This ensures that the germicidal light emitted by the germicidal lamp 96 reaches as much of the water in the clean water tank 20 as possible.

[0126] FIG20 is a cross-sectional view of another structure of the water purification tank 20 in the water purifier 100 provided in an embodiment of the present application, FIG21 is a cross-sectional view of another angle of another structure of the water purification tank 20 in the water purifier 100 provided in an embodiment of the present application, and FIG22 is a partial enlarged view of the Y portion of FIG21. Referring to FIG20, FIG21, and FIG22, in the aforementioned solution, it is necessary to open a hole in the front panel 873 and install the germicidal lamp 96, which affects the user's visual experience. To this end, it is possible to consider setting the sterilization unit 90 to a wireless mode. In a specific implementation, the sterilization unit 90 may include a lamp holder 98, which is inserted into the first mounting opening 291 and is sealed to the first mounting opening 291. For example, the sealing connection method can be a flange portion 982 provided at the first end of the lamp holder 98, the flange portion 982 overlaps the edge of the first mounting opening 291, and the flange portion 982 and the edge of the first mounting opening 291 are provided with a third sealing ring 981. Now, the germicidal lamp 96 can be installed in the end portion towards the inner side of the clean water tank 20 of the lamp holder 98. Like this, the germicidal lamp 96 directly extends into the inside of the clean water tank 20, and compared with the previous scheme, the irradiation range in the clean water tank 20 is larger.

[0127] Continuing with Figure 22 , the sterilization unit 90 further includes a second mounting member 983 that fits over the lamp holder 98. This second mounting member 983 can be located outside the clean water tank 20, for example, within the first mounting groove 29. It is used to apply force toward the flange 982 toward the outside of the clean water tank 20, causing the flange 982 to press the third sealing ring 981 against the inner wall of the clean water tank 20. In practice, the second mounting member 983 can rest against the bottom wall of the first mounting groove 29. The second mounting member 983 and the lamp holder 98 can be threadedly engaged. In this case, the flange 982, the first sealing ring 94, and the second mounting member 983 press against the bottom of the first mounting groove 29 from both the inside and outside of the clean water tank 20. To position the germicidal lamp 96, a mounting groove is formed on the end of the lamp holder 98 facing the inside of the clean water tank 20, into which the germicidal lamp 96 is sealed.

[0128] In the embodiment of the present application, the sterilization unit 90 further includes a wireless component 99, which includes a wireless transmitting unit 991 and a wireless receiving unit 992. The wireless transmitting unit 991 is mounted on the inner wall of the housing 80 and is electrically connected to the power supply circuit board (not shown) of the water purifier 100. The wireless receiving unit 992 is mounted on the end of the lamp holder 98 facing the outside of the clean water tank 20. When the clean water tank 20 is supported on the support member 81, the wireless transmitting unit 991 and the wireless receiving unit 992 are arranged relative to each other to supply power to the sterilization lamp 96 via the wireless receiving unit 992.

[0129] Figure 23 is a schematic structural diagram of a water vapor separator provided in an embodiment of the present application; Figure 24a is a schematic cross-sectional structural diagram of a water vapor separator provided in an embodiment of the present application; Figure 24b is a schematic structural diagram of a water purifier provided in an embodiment of the present application from another angle; Figure 25 is a partial enlarged view of position Z in Figure 24a; Figure 26 is a schematic structural diagram of a water vapor separator provided in an embodiment of the present application from another angle; Figure 27 is a partial cross-sectional view of a water vapor separator provided in an embodiment of the present application; Figure 28 is a cross-sectional view of a water vapor separator provided in an embodiment of the present application from another angle. It will be understood that, in order to facilitate observation of the internal structure, Figure 26 shows a schematic diagram of the first-stage separator cover 641 in an open state relative to the first-stage separator main body 64.

[0130] In the embodiment of the present application, as described above, the water vapor separator 60 is used to separate the steam in the heated purified water. The water vapor separator 60 is provided with a water vapor separation outlet 61 , which forms the water inlet of the water purifier 100 .

[0131] The water vapor separator in the related art has the problem of poor steam separation effect. The water flowing out from the water vapor separation outlet contains a lot of steam. In order to avoid this problem, the water purifier in the related art often controls the outlet water temperature at around 93°C to reduce the steam content in the outlet water. Therefore, the water purifier in the related art has the problem that the outlet water temperature is not high enough.

[0132] In order to solve this problem, the embodiment of the present application further improves the structure of the water vapor separator 60.

[0133] Specifically, in combination with Figures 23, 24a, and 25, the water vapor separator 60 includes a primary water vapor separation body 63 and a secondary water vapor separation body 65 for performing water vapor separation. The primary water vapor separation body 63 and the secondary water vapor separation body 65 are respectively constructed with a primary water vapor separation chamber K and a secondary water vapor separation chamber L that are interconnected.

[0134] The first-level water vapor separation body 63 is provided with a water vapor separation water inlet 631 and a first air outlet 632 connected to the first-level water vapor separation chamber K, while the water vapor separation water outlet 61 and the water vapor separation air outlet 62 are arranged on the second-level water vapor separation body 65 and connected to the second-level water vapor separation chamber L. The water vapor separation water inlet 631 is used to connect to the hot water supply source.

[0135] The water vapor separation water inlet 631 is arranged on the bottom wall 633 of the first-level water vapor separation chamber. The bottom wall 633 of the first-level water vapor separation chamber is provided with a first guide tube 635 extending toward the top wall 634 of the first-level water vapor separation chamber. The first guide tube 635 is connected to the water vapor separation water inlet 631. The top wall 634 of the first-level water vapor separation chamber is also provided with a guide wall 66 extending toward the bottom wall 633 of the first-level water vapor separation chamber. The guide wall 66 is blocked on the circumferential outside of at least part of the pipe section of the first guide tube 635.

[0136] The water vapor separator 60 includes a primary water vapor separation body 63 and a secondary water vapor separation body 65 for water vapor separation. The primary water vapor separation chamber K in the primary water vapor separation body 63 and the secondary water vapor separation chamber L in the secondary water vapor separation body 65 are connected to each other. In this way, the water vapor mixture first enters the primary water vapor separation body 63 for a first water vapor separation, and then enters the secondary water vapor separation body 65 for a second water vapor separation, and the water vapor separation effect is better.

[0137] On the other hand, the water vapor separation water inlet 631 is set on the bottom wall 633 of the first-level water vapor separation chamber, and the bottom wall 633 of the first-level water vapor separation chamber is provided with a first guide tube 635 extending toward the top wall 634 of the first-level water vapor separation chamber. In this way, the water vapor mixture entering the first-level water vapor separation chamber K from the water vapor separation water inlet 631 enters the first guide tube 635. In addition, the top wall 634 of the primary water vapor separation chamber is further provided with a drainage wall 66 extending toward the bottom wall 633 of the primary water vapor separation chamber. The drainage wall 66 is disposed on the circumferential outer side of at least a portion of the first flow conduit 635. As a result, after the water vapor mixture in the first flow conduit 635 escapes from the first flow conduit 635, it rushes toward the top wall 634 of the primary water vapor separation chamber. The top wall 634 of the primary water vapor separation chamber can break up the water vapor mixture, separating some of the steam in the water vapor mixture from the water flow. The water then flows downward along the drainage wall 66 into the bottom of the primary water vapor separation chamber K, and the steam is discharged upward from the primary water vapor separation body 63 through the first outlet 632. As described above, when the water vapor separation effect is good, the amount of steam contained in the water is low, and the water outlet temperature of the water purifier can be set higher to meet the user's water needs.

[0138] The hot water source may be, for example, a heater 55, whose water outlet 551 may be connected to the water vapor separation water inlet 631 via the fifth pipe 105. Of course, in other embodiments, the water outlet 551 may also be directly connected to the water vapor separation water inlet 631.

[0139] In the embodiment of the present application, the setting height of the bottom end of the guide wall 66 facing the bottom wall 633 of the first water vapor separation chamber is lower than the setting height of the top end of the first guide pipe 635 facing the first water vapor separation chamber K.

[0140] By making the bottom end of the guide wall 66 lower than the top end of the first guide tube 635, it can be ensured that the water vapor mixture rushing out of the first guide tube 635 can be broken up by the top wall 634 of the first-level water vapor separation chamber, and the broken up water flow can reliably fall along the guide wall 66 onto the bottom wall 633 of the first-level water vapor separation chamber, and will not enter the first guide tube 635 from the top end of the first guide tube 635.

[0141] Further, referring to FIG. 27 , the guide wall 66 and a portion of the side wall 636 of the primary water vapor separation chamber define a scattered cavity M, and a portion of the top side of the first guide pipe 635 extends into the scattered cavity M.

[0142] In some embodiments, at least a portion of the outer tube wall of the first flow guide tube 635 and the inner wall of the first-stage water vapor separation chamber K are constructed as an integral piece to facilitate the processing and manufacturing process.

[0143] 24a and 27 , further, a first mounting pipe 637 is provided on the outer wall of the primary water vapor separator 63, which is coaxial with and communicates with the first flow conduit 635. This facilitates the introduction of the water vapor mixture flowing out of the water outlet 551 of the heater into the first flow conduit 635.

[0144] Furthermore, the first air outlet 632 is provided on a side wall 636 of the primary moisture separation chamber. A second flow guide tube 638 is provided on the side wall 636 of the primary moisture separation chamber, extending toward the top wall 634 of the primary moisture separation chamber. The second flow guide tube 638 is connected to the first air outlet 632. A flow guide wall 66 extends between the first flow guide tube 635 and the second flow guide tube 638. The top end of the first flow guide tube 635 is separated from the top end of the second flow guide tube 638 by the flow guide wall 66.

[0145] With such an arrangement, the bottom end of the guide wall 66 is actually arranged at a height lower than the top end of the second guide tube 638. After the water vapor mixture flushed out through the first guide tube 635 is broken up by the top wall 634 of the first-level water vapor separation chamber, the water flows downward from the guide wall 66 toward one side of the first guide tube 635. Due to the obstruction of the guide wall 66, it will not enter the second guide tube 638.

[0146] Similar to the first flow guide tube 635 , at least a portion of the outer tube wall of the second flow guide tube 638 and the inner wall of the first-stage water vapor separation chamber K are constructed as an integral piece, which facilitates the processing and manufacturing process.

[0147] In this embodiment, a second mounting tube 639 is provided on the outer wall of the primary vapor separator 63, coaxial with and interconnected with the second flow guide tube 638. This facilitates the degassing of steam out of the primary vapor separation chamber K. In a specific implementation, for example, referring to FIG. 24a , the second mounting tube 639 can be connected to the vapor separation outlet 62 on the secondary vapor separator 65 via the sixth conduit 106.

[0148] 26 and 27 , the primary water vapor separator 63 further includes a primary separator body 64 and a primary separator cover 641 covering the primary separator body 64. The guide wall 66 is provided on the primary separator cover 641. This arrangement can facilitate the processing.

[0149] 24a, 27 and 28, the first-level water vapor separation body 63 is provided with a first connecting port 642 communicating with the first-level water vapor separation chamber K, and the second-level water vapor separation body 65 is provided with a second connecting port 651 communicating with the second-level water vapor separation chamber L, and the first connecting port 642 is communicated with the second connecting port 651.

[0150] The top wall 652 of the secondary moisture separation chamber is further provided with a third flow guide tube 655 extending toward the bottom wall 653 of the secondary moisture separation chamber. The third flow guide tube 655 is connected to the second connection port 651. The bottom wall 653 of the secondary moisture separation chamber is provided with a stopper wall 654 extending toward the top wall 652 of the secondary moisture separation chamber. The stopper wall 654 is located between the circumferential outer side of the third flow guide tube 655 and the moisture separation outlet 61.

[0151] A third flow guide 655 extending toward the bottom wall 653 of the secondary water vapor separation chamber is provided through the top wall 652 of the secondary water vapor separation chamber. Water flowing out of the primary water vapor separation chamber K falls onto the bottom wall 653 of the secondary water vapor separation chamber and is broken up again, so that part of the steam mixed in the water flow is separated from the water flow. The bottom wall 653 of the secondary water vapor separation chamber is provided with a stop wall 654 extending toward the top wall of the secondary water vapor separation chamber. The stop wall 654 is provided around the third flow guide 655. The water flow, which has been dispersed and separated on the bottom wall 653 of the secondary water vapor separation chamber, hits the stop wall 654 as it flows toward the water vapor separation outlet 61, and is dispersed again, undergoing water vapor separation. The separated steam then flows out of the secondary water vapor separation chamber L through the water vapor separation outlet 62. The water flow, which has been dispersed again after passing through the stop wall 654, now contains a lower amount of steam and can flow out of the secondary water vapor separation chamber L through the water vapor separation outlet 61. In this way, the water flow entering the secondary water vapor separation chamber L, after undergoing two water vapor separations, is used in combination with the primary water vapor separator 63 to achieve a better water vapor separation effect on hot water.

[0152] 24a and 28 , further, the bottom wall 653 of the secondary water vapor separation chamber is constructed with a retention groove N spaced apart from the water vapor separation outlet, and the bottom end of the third guide pipe 655 extends into the retention groove N.

[0153] By making the bottom end of the third flow conduit 655 extend into the retention tank N, that is, the height of the bottom end of the third flow conduit 655 is lower than the height of the edge of the notch of the retention tank N. In this way, when water intake stops, the water flowing out of the primary water vapor separation chamber K will rush out of the third flow conduit 655 due to the inertia of the water flow and the adhesion of water, causing the water level in the third flow conduit 655 to be lower than the water level in the retention tank N (which is full of water). As time goes by, the water in the third flow conduit 655 gradually stabilizes, and some of the water in the retention tank N returns to the third flow conduit 655, making the water level in the third flow conduit 655 equal to the water level in the retention tank N, thereby lowering the water level in the retention tank N. The portion below the edge of the slot is not full. At this time, if there are residual water droplets in the first-level water vapor separation chamber K and they drip into the second-level water vapor separation body 65, the water levels in the retention slot N and the third guide tube 655 will rise accordingly. However, due to the viscosity of water, it will adhere to the side slot wall of the retention slot N, that is, the water in the retention slot N will not flow out. Therefore, no water droplets will drip from the water vapor separation outlet 61. In this way, the effect of quickly sealing the water when stopping water intake is achieved, effectively improving the problem of water leakage at the water intake of the water purifier 100.

[0154] In the prior art, air easily enters the inner cavity of the water vapor separator 60 through the water vapor separation outlet 61, which can easily breed bacteria over time. Furthermore, since this inner cavity is inaccessible to users, the retention groove N is provided. Therefore, after water withdrawal stops, the bottom end of the third flow guide tube 655 extends into the retention groove N, creating a liquid seal. This prevents outside air from entering the inner cavity of the water vapor separator 60, particularly the primary water vapor separator 63, inhibiting bacterial growth and ensuring cleaner and more hygienic water output from the water vapor separator 60.

[0155] In some embodiments, the stop wall 654 and a portion of the side wall 656 of the secondary water vapor separation chamber define the aforementioned retention groove N. This configuration can reduce the volume of the secondary water vapor separation body 65 compared to a groove formed on the bottom wall 653 of the secondary water vapor separation chamber.

[0156] In combination with Figures 23 and 24a, further, a first matching tube 657 connected to the first connecting port 642 is provided on the outer wall of the first water vapor separation body 63, and a first matching slot 658 connected to the second connecting port 651 is provided on the second water vapor separation body 65. The first matching tube 657 and the first matching slot 658 are plugged into each other to connect the first connecting port 642 and the second connecting port 651.

[0157] It can be understood that in order to avoid water leakage between the first mating tube 657 and the first mating slot 658, a seal 660 can be provided between the outer wall of the first mating tube 657 and the inner groove wall of the first mating slot 658. The seal 660 can be an annular sealing ring, which is mounted on the outer periphery of the first mating tube 657 and clamped between the first mating tube 657 and the first mating slot 658.

[0158] In this way, the primary water vapor separator 63 and the secondary water vapor separator 65 are plugged and mated, making the fit relatively secure. Of course, it is understood that, referring to Figure 23 , the primary water vapor separator 63 and the secondary water vapor separator 65 can also be fixedly connected by fasteners 643 to further secure the connection. The outer circumferential wall of the first mating tube 657 can also be provided with a plurality of circumferentially spaced positioning ribs 659. The positioning ribs 659 abut against the notches of the first mating slot 658 to assist in positioning the first mating tube 657 and the first mating slot 658.

[0159] In combination with Figures 23 and 24a, further, the secondary water vapor separation body 65 includes a secondary water vapor separation body 671 and a secondary water vapor separation cover body 673 covered on the secondary water vapor separation body 671, the first mating slot 658 is arranged on the top side of the secondary water vapor separation cover body 673, and the third guide tube 655 is arranged on the bottom side of the secondary water vapor separation cover body 673 and is connected to the first mating slot 658.

[0160] Thus, after the first matching tube 657 is inserted into the first matching slot 658, water flowing out of the first matching tube 657 can directly enter the third flow guide tube 655. In a specific implementation, the first matching tube 657 and the third flow guide tube 655 can be coaxially arranged.

[0161] Furthermore, the water vapor separation outlet 61 is disposed on the bottom wall 653 of the secondary water vapor separation chamber. The bottom wall 653 of the secondary water vapor separation chamber is configured as an inclined wall structure that tilts toward the water vapor separation outlet 61. In this way, water flowing out of the retention tank N can more easily flow along the inclined wall into the water vapor separation outlet 61.

[0162] 24a and 27 , further, the water vapor separation outlet 62 is provided on the bottom wall 653 of the secondary water vapor separation chamber and is located between the water vapor separation outlet 61 and the stop wall 654 ;

[0163] A fourth flow guide tube 672 extending toward the top wall 652 of the secondary water vapor separation chamber is provided on the bottom wall 653 of the secondary water vapor separation chamber. The fourth flow guide tube 672 is connected to the water vapor separation outlet 62, and a distance is provided between the top end of the fourth flow guide tube 672 and the top wall 652 of the secondary water vapor separation chamber.

[0164] In this way, the steam separated in the secondary water vapor separation chamber L rises upward and gathers at the top of the secondary water vapor separation chamber L. It can enter the fourth guide tube 672 from the top end of the fourth guide tube 672 and flow out of the secondary water vapor separation chamber L from the water vapor separation outlet 62.

[0165] Furthermore, the water vapor separation air outlet 62 is located on the bottom wall 653 of the secondary water vapor separation chamber near the water vapor separation water outlet 61 .

[0166] In the embodiment of the present application, an avoidance recess O is provided on the inner wall of the secondary water vapor separation cover 673 at a position corresponding to the fourth guide tube 672 , and the top end of the fourth guide tube 672 extends into the avoidance recess O.

[0167] In this way, even if the length of the fourth guide pipe 672 is longer, the external contour size of the secondary water vapor separation body 65 will not be increased.

[0168] Furthermore, the water vapor separation outlet 62 is located between the water vapor separation outlet 61 and the second connecting port 651 , and the first connecting port 642 corresponds to the second connecting port 651 .

[0169] Furthermore, the water vapor separation outlet 61 , the water vapor separation air outlet 62 and the first connecting port 642 are arranged in a row.

[0170] Referring to Figure 24b, as previously described, the outer wall of the housing 80 is provided with a carrier 81, on which a water collection box 85 is formed. When drawing water, the user can place a water container on the water collection box 85 to draw water from the water vapor separation outlet 61. The water vapor separator 60, particularly the water vapor separation outlet 61 and the water vapor separation air outlet 62, must be positioned above the carrier 81 (water collection box 85) and aligned with the position of the carrier 81.

[0171] Of course, as mentioned above, an avoidance gap needs to be set on the shell 80 to allow part of the structure of the water vapor separator 60 to be exposed to the outside of the shell 80. For example, the water vapor separation outlet 61 and the water vapor separation gas outlet 62 need to be located on the outside of the shell 80. On the one hand, it is convenient to take water, and on the other hand, it is also convenient to prevent the discharged gas from entering the interior of the shell 80 and affecting the various components inside the shell 80.

[0172] Furthermore, the first connection port 642 is disposed on the bottom wall 633 of the primary moisture separation chamber, which is configured as an inclined structure that slopes toward the first connection port 642. This allows water flowing downward from the drainage wall 66 to more easily flow out of the primary moisture separation chamber K through the first connection port 642. As previously described, the moisture separation water inlet 631 and the first connection port 642 are both located on the bottom wall 633 of the primary moisture separation chamber, but the moisture separation water inlet 631 is positioned higher than the first connection port 642, allowing the fluid flowing out of the first guide pipe 635 to be more easily directed from the bottom wall 633 of the primary moisture separation chamber to the first connection port 642.

[0173] Furthermore, as previously mentioned, the water vapor separation outlet 62 can communicate with the interior of the filter housing 42. Thus, the steam discharged from the water vapor separation outlet 62 can be discharged into the atmosphere through the filter housing 42. Of course, as another possible embodiment, the water vapor separator 60 can be partially disposed within the housing 80, with the water vapor separation outlet 61 and the water vapor separation outlet 62 both disposed outside the housing 80. This arrangement facilitates the dissipation of steam discharged from the water vapor separation outlet 62 outside the housing.

[0174] In addition, in the embodiment of the present application, the cross-sectional area of ​​the water vapor separation outlet 62 is greater than or equal to 22 mm 2 Since the steam discharged from the water vapor separation outlet 62 will form condensed water after contacting the outside air, the condensed water can directly flow into the water cup outside. If the cross-sectional area of ​​the water vapor separation outlet 62 is too small, the condensed water will form a water film when passing through the water vapor separation outlet 62, making it difficult to exhaust, causing the steam to be discharged from the water vapor separation outlet 61 together with the water flow, resulting in interruption and jetting. When the cross-sectional area of ​​the water vapor separation outlet 62 is greater than or equal to 22mm 2 This situation can be avoided.

[0175] Furthermore, the cross-sectional area of ​​the first connection port 642 is greater than or equal to 22 mm 2 This can prevent the water from forming a water film due to the small cross-sectional area when the water flows out of the first water vapor separation chamber M through the first connecting port 642, resulting in poor drainage.

[0176] The following describes the operation of the water shutoff operation of the water vapor separator 60 with reference to Figure 28 . In Figure 28 , the water shutoff process of the water vapor separator is divided into six states. State (a) represents the water level during water production. State (b) corresponds to the moment water withdrawal stops. Due to the inertia of the water flow and the adhesive properties of the water, the water flowing out of the first-stage water vapor separation chamber K rushes out of the third flow conduit 655, causing the water level in the third flow conduit 655 to fall below the level of the water in the retention tank N. State (c) represents the gradual stabilization of the water in the third flow conduit 655 over time, with some of the water in the retention tank N returning to the third flow conduit 655. This causes the water level in the third flow conduit 655 to be equal to the water level in the retention tank N, thereby lowering the water level in the retention tank N below the top of the stop wall 654. In state (d), if residual water droplets in the primary water vapor separation chamber K drip into the secondary water vapor separation body 65, the water level in the retention tank N and the third flow guide 655 will rise accordingly. However, due to the viscosity of water, it will adhere to the side of the stop wall 654 near the retention tank N. In other words, the water in the retention tank N will not flow over the stop wall 654, and thus no water droplets will drip from the water vapor separation outlet 61. This achieves the effect of quickly sealing the water supply when water withdrawal stops. State (e) corresponds to a schematic diagram of the stop wall 654 blocking the dripping water in the retention tank.

[0177] The technical features of the above-described embodiments can be combined arbitrarily.

Therefore, the scope of protection of the patent of this invention shall be based on the attached claims.
