Description

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 pursue a high-quality life, and water purifiers are undoubtedly one of the best choices. The water purifiers in the related art usually include a heater and a water vapor separator. The filtered water will be heated by the heater, separated by the water vapor in the water vapor separator, and then provided to the user. However, the water vapor separator in the related art has the problem of poor steam separation effect. The water flowing out of the water outlet of the water vapor separator often contains more steam. In order to avoid this problem, the water purifiers in the related art often control the outlet water temperature at around 93°C to reduce the steam content in the outlet water.

[0068] The water purifier 100 according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0069] Figure 1 A schematic diagram of the structure of a water purifier 100 provided in an embodiment of the present application; Figure 2 A schematic diagram of the exploded structure of a water purifier 100 provided in an embodiment of the present application; Figure 3 This is a schematic diagram of the exploded structure of the water purifier 100 provided in the embodiment of the present application from another angle. Figure 4 This is a cross-sectional view of the liquid level box 10 in the water purifier 100 provided in an embodiment of the present application.

[0070] Reference Figure 1 , Figure 2 , Figure 3 , an embodiment of the present application provides a water purifier 100 for purifying water from a water source to be filtered.

[0071] 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 pump 50, a heater 55 and a water vapor separator 60. The filter 40 is in communication with the manifold inner cavity C of the manifold 30, the manifold 30 is in communication with the clean water tank 20 and the liquid level box 10 respectively, and the pump 50 is in communication with the manifold inner cavity C of the manifold 30 and the heater 55 respectively, so that the pump 50 can pump water in the liquid level box 10 and the clean water tank 20 to the heater 55 through 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.

[0072] With such 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 simultaneously passes through the communicating vessel 30 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 from the water vapor separator 60 .

[0073] The filter 40 is used to connect with the water source to be purified so as to filter the water source to be purified. The clean water tank 20 is used to store the filtered clean water. The liquid level box 10 is provided with a water level sensor 12. The clean water tank 20 is connected with the liquid level box 10 through the communicating vessel 30. Both the clean water tank 20 and the liquid level box 10 are connected with the atmosphere. According to the communicating vessel principle, the water level in the liquid level box 10 can reflect the water level in the clean water tank 20.

[0074] 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 .

[0075] Reference Figure 2 , Figure 3 When the user needs to take clean water, the water pump 50 starts working, and the water in the clean water tank 20 and the liquid level box 10 is synchronously pumped 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.

[0076] When the water level in the liquid level box 10 is lower than the high liquid level described below, the filter 40 operates 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.

[0077] The various parts of the water purifier 100 will be described in detail below with reference to the accompanying drawings.

[0078] Reference Figure 1 and Figure 2 The shell 80 is hollow inside 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 together enclose a receiving cavity, and the filter 40, the communicating vessel 30, the liquid level box 10, the water pump 50 and the heater 55 are arranged in the receiving cavity. The rear panel 870 and the front panel 873 are arranged on the side of the base 872 to form the main body of the shell 80, and the top cover 871 covers the front panel 873 and the rear panel 870.

[0079] A bearing member 81 is further provided on the outer wall of the shell 80 , and the clean water tank 20 is detachably disposed on the bearing member 81 .

[0080] 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 .

[0081] In this way, the clean water tank 20 is detachably arranged outside the housing 80, so that when a user needs a large amount of water, he can directly remove the clean water tank 20 to get water. In addition, the clean water tank 20 can be easily removed for maintenance operations such as cleaning.

[0082] In addition, combined Figure 1 and Figure 2 , part of the structure of the water vapor separator 60 penetrates the housing 80 and extends to the outside of the housing 80, and the water vapor separation outlet 61 is located on the part of the water vapor separator 60 extending to the outside of the housing 80. In this way, it is convenient for the user to take water from the water vapor separation outlet 61 outside the housing 80. Exemplarily, a avoidance port 8731 may be formed on the front panel 873, and the water vapor separation outlet 61 extends to the outside of the housing 80 through the avoidance port 8731.

[0083] In the present application, refer to Figure 4 The water level sensor 12 is configured as a float sensor, and the water level sensor 12 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 sequence 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.

[0084] The water level sensor 12 is configured to detect the liquid level in the liquid level box 10 (also called the water level when the liquid level box contains water), and when the first float 121 abuts against the first upper baffle 123, it is determined that the liquid level is at a high level, and when the second float 122 abuts against the second lower baffle 126, it is determined that the liquid level is at a low level.

[0085] With this arrangement, whether it is detecting a high liquid level or a low liquid level, the corresponding float stroke is relatively short. Compared with the solution of setting only one float, it avoids the situation where the float has a long stroke at different liquid levels and is easily stuck, resulting in inaccurate detection results or float failure.

[0086] In the 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 when the liquid level in the liquid level box 10 is at a high liquid level, thereby stopping water production; 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.

[0087] In the embodiment of the present application, the water purifier 100 further includes an exhaust component 70 .

[0088] The exhaust member 70 is configured with a first chamber E communicating with the atmosphere, and the first chamber E is communicated with a filter liquid outlet of the filter 40 (not shown).

[0089] As mentioned above, the manifold 30 is configured with a manifold inner cavity C, which 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.

[0090] 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, thereby 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.

[0091] Continue to refer to Figure 3 The liquid level box 10 is provided with an air outlet 13 connected to the atmosphere; the exhaust member 70 is provided on the liquid level box 10, and the first chamber E is connected to the liquid level box inner cavity A of the liquid level box 10 to be connected to the atmosphere through the air outlet 13. In this way, the liquid level box 10 and the exhaust member 70 can be provided as one body, which can reduce the number of parts and save installation steps.

[0092] Further, refer to Figure 5 The exhaust member 70 is arranged on the outer side wall of the liquid level box 10, and the exhaust member 70 and the side walls facing each other of the liquid level box 10 are provided with communicating ports 14 communicating with each other so that the first chamber E is communicated with the inner chamber A of the liquid level box. The liquid level box 10 is communicated with the atmosphere through the first chamber E communicating with the inner chamber A of the liquid level box, and thus the first chamber E of the exhaust member 70 is communicated with the atmosphere through the inner chamber A of the liquid level box.

[0093] For the connection between the various components, combined Figure 3 , Figure 4 , Figure 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 may be communicated with the filter liquid outlet through the first pipe 101, and the exhaust member liquid outlet 73 may be communicated with the communicating vessel liquid inlet 33 of the communicating vessel 30 through the second pipe 102;

[0094] The heights of the communication port 14 on the exhaust member 70 and the liquid level box 10 relative to the bottom wall of the liquid level box 10 are higher than the height of the exhaust member liquid inlet 72. This can prevent water entering the exhaust member 70 from the exhaust member liquid inlet 72 from entering the liquid level box 10 from the communication port 14.

[0095] Reference Figure 3 Furthermore, the communicating vessel liquid inlet 33 is connected to the filter liquid outlet of the filter 40 through the exhaust member 70, the diameter of the communicating vessel liquid inlet 33 is greater than 6 mm, and the inner diameter of the second pipe 102 is greater than 6 mm.

[0096] 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 impossible for water to enter the communicating vessel 30 from the exhaust component 70 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 connecting 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.

[0097] Figure 6 This is a schematic diagram of the structure of the filter 40 in the water purifier 100 provided in an embodiment of the present application.

[0098] Reference Figure 6 The filter 40 includes a filter shell 42 and a filter body 43. The filter shell 42 is configured with a filter cavity 44 with one end open (connected to the atmosphere). The filter body 43 is arranged in the filter cavity 44. The air outlet 13 provided on the liquid level box 10 is connected to the inside of the filter shell 42 of the filter 40.

[0099] The inside of the filter housing 42, that is, the filter inner cavity 44 is connected to the atmosphere, and the air outlet 13 is connected to the inside of the filter housing 42 of the filter 40, so that the liquid level box 10 is connected to the atmosphere. In addition, the clean water tank 20 is also connected to the atmosphere. Therefore, when the water purifier 100 takes water from the liquid level box 10 and the clean water tank 20 through the communicating vessel 30, or the water filtered by the filter 40 enters the liquid level box 10 and the clean water tank 20 through the communicating vessel 30, according to the communicating vessel principle, the water level in the liquid level box 10 and the water level in the clean water tank 20 can be kept roughly 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.

[0100] The liquid level box 10 (the air outlet 13 ) is in communication with the interior of the filter 40 (that is, the filter inner cavity 44 inside the filter housing 42 ) through the third pipe 103 .

[0101] 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 opened on the box cover 16 .

[0102] In specific implementation, as mentioned above, the filter housing 42 is provided with a filter housing air inlet 41 communicating with 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.

[0103] It is understandable that the filter cavity must be provided with an opening in order to access the filter body 43, 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.

[0104] Exemplarily, the filter housing 42 is provided with a filter extension pipe 421 communicating with the inside of the filter housing 42 through the filter housing air inlet 41, the box cover 16 is provided with a liquid level box extension pipe 161 at a position corresponding to the air outlet 13, and the two ends of the third pipe 103 are respectively connected to the filter extension pipe 421 and the liquid level box extension pipe 161. Such an arrangement facilitates the connection of the two ends of the third pipe 103 with the filter housing 42 and the liquid level box 10.

[0105] Further, the box body 15 is provided with a first mounting portion 162, the filter housing 42 is provided with a second mounting portion 422, and 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 can be understood that the number of the first mounting portion 162 and the second mounting portion 422 can also be multiple, for example, part of the first mounting portion 162 can also be provided on the box body 15, and the second mounting portion 422 corresponding to the part of the first mounting portion 162 is provided at a position on the filter housing corresponding to the first mounting portion 162.

[0106] 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 .

[0107] The water vapor separator 60 includes a water vapor separation outlet 62 and the aforementioned water vapor separation water outlet 61, and the water vapor separation outlet 62 is communicated 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.

[0108] In the embodiment of the present application, the filter 40 includes three-stage filtration to achieve a better filtering effect.

[0109] In specific implementation, the filter body 43 includes a first-stage filter 431, a second-stage filter 432, and a third-stage filter 433 connected in sequence, and the filter cavity 44 includes a first-stage filter cavity 441, a second-stage filter cavity 442, and a third-stage filter cavity 443 that are connected. The first-stage filter 431 is accommodated in the first-stage filter cavity 441, the second-stage filter 432 is accommodated in the second-stage filter cavity 442, the third-stage filter 433 is accommodated in the third-stage filter cavity 443, and the air outlet 13 is connected to the first-stage filter cavity 441.

[0110] By configuring the filter body 43 to include a primary filter 431 , a secondary filter 432 , and a tertiary filter 433 which are connected in sequence, a better filtering effect can be achieved.

[0111] Furthermore, the water purifier 100 further includes a booster pump, which is used to pump the water to be purified into the filter body 43, and the water source is purified in the filter body 43. By providing a booster pump as a power source when the purifier makes water, in addition to a water source with a certain water pressure such as a tap water pipe, it can be applied to different types of water sources, such as water sources in water storage tanks in daily life.

[0112] In the present application embodiment, combined Figure 3 , Figure 4As mentioned above, the water pump 50 is connected to the communicating vessel 30 and the heater 55 respectively, and is used to pump the water in the liquid level box 10 and the clean water tank 20 to the heater 55 through the communicating vessel 30. The water vapor separator 60 is connected to the heater 55, and is used to separate the water vapor of the water heated by the heater 55.

[0113] With such arrangement, when the user draws water, the water pump 50 pumps 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 from the water vapor separator 60 .

[0114] Continue 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.

[0115] As for the connection between the clean water tank 20 and the atmosphere, for example, reference can be made to Figure 4 The clean water tank 20 includes a clean water tank body 25 and a water tank cover 26 which is openably and closably covered on the clean water tank body 25. A gap is provided between the clean water tank body 25 and the water tank cover 26 so that the clean water tank 20 is connected to the atmosphere. In this way, when a user needs a large amount of water, the user can open the water tank cover 26 to pour it out.

[0116] Furthermore, the water vapor separation outlet 62 is disposed at the top end of the water vapor separator 60 , and the third pipe 103 and the fourth pipe 104 are located at one side of the top end of the liquid level box 10 and the water vapor separator 60 .

[0117] In this way, the lengths of the third pipe 103 and the fourth pipe 104 can be set shorter, and combined with the upward characteristic of water vapor, the water vapor can be discharged more smoothly.

[0118] Figure 7 This is a schematic cross-sectional view of a water purifier 100 provided in an embodiment of the present application.

[0119] In the embodiment of the present application, as mentioned above, the communicating vessel 30 is respectively connected to the liquid level box 10 and the clean water tank 20. Figure 3 and Figure 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.

[0120] Further, refer to Figure 3 , Figure 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 connecting port 11 relative to the bottom of the water purifier 100 is higher than the setting height of the communicating vessel liquid outlet 38.

[0121] With such arrangement, the liquid in the liquid level box 10 can flow out of the communicating vessel 30 more smoothly through the communicating vessel liquid outlet 38, thereby avoiding the situation where the liquid level box 10 has poor liquid discharge and water accumulates in the liquid level box 10, resulting in the clean water provided to the water intake being water mixed with the accumulated water.

[0122] In a specific implementation, the communicating vessel 30 is provided with an extension tube 39, which passes through the wall of the communicating vessel 30 from the outside (e.g., the top side) of the communicating vessel 30 and extends to the bottom position of the communicating vessel inner cavity C. The end of the extension tube 39 located in the communicating vessel inner cavity C forms a communicating vessel liquid outlet 38.

[0123] 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, and 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.

[0124] Furthermore, the height of the communicating vessel liquid 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 communicating vessel liquid outlet 38. The communicating vessel liquid inlet 33 can be set at the top of the communicating vessel 30. Thus, the purified water entering the communicating vessel 30 from the communicating vessel liquid inlet 33 can smoothly enter the liquid level box 10 and the clean water tank 20.

[0125] Figure 8 This is a schematic diagram of another structure of the communicating vessel 30 in the water purifier 100 provided in an embodiment of the present application.

[0126] Reference Figure 8 Since the water production and water intake of the water purifier 100 must pass through the communicating vessel 30, during the water production process, the air cannot be discharged smoothly due to the small volume of the communicating vessel 30. It can be considered to make the inner cavity C of the communicating vessel communicate with the filter outlet of the filter 40. For example, the filter outlet of the filter 40 can be communicated with the communicating vessel inlet 33 through a pipeline (not shown). At this time, the communicating vessel inlet 33 can be communicated with the exhaust member 70 at the same time, or only communicated with the filter outlet, but not communicated with the exhaust member 70.

[0127] Furthermore, an exhaust portion 701 connected to the atmosphere is provided on the manifold 30, and the exhaust portion 701 is connected to the inner cavity C of the manifold, so that during the water making and taking process of the water purifier 100, air can be smoothly discharged from the manifold 30, so that the water flow can flow smoothly, 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 only connected to the filter liquid outlet but not to the exhaust member 70, the water filtered by the filter 40 does not pass through the exhaust member 70, but directly enters the inner cavity C of the manifold from the manifold liquid inlet 33, and is exhausted by the exhaust portion 701.

[0128] In specific implementation, the top of the communicating vessel 30 is provided with an exhaust port 301 connected to the communicating vessel inner cavity C, and the exhaust port 301 forms an exhaust portion 701. Of course, in order to facilitate the smooth discharge of air in the communicating vessel 30, the exhaust port 301 is also provided with an exhaust pipe 302, and the exhaust pipe 302 extends along the height direction of the water purifier 100.

[0129] 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, and can also 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.

[0130] Combine the following Figure 3 , Figure 7 , describing the working process of the water purifier 100 of the embodiment of the present application.

[0131] When users need to get clean water, Figure 3 As shown by the dotted arrow in the middle, the water pump 50 is working, 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 communicating vessel liquid outlet 38, and enters the heater 55 connected to the water pump 50. When the clean water enters the heater 55, the heater 55 can heat the clean water when it is working, and the clean water will not be heated when the heater 55 is not working. The water entering the heater 55 finally enters the water vapor separator 60. After the heated clean water is separated from 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.

[0132] In the water production process, Figure 3 , Figure 4As shown by the solid arrow, the booster pump (not shown) works, the filter 40 purifies the water source to be purified, and transports the purified water to the first chamber E of the exhaust member 70 through the first pipe 101, and enters the inner cavity C of the communicating vessel through the liquid outlet 73 of the exhaust member, the second pipe 102, and the liquid inlet 33 of the communicating vessel. Part of the purified water entering the inner cavity C of the communicating vessel enters the clean water tank 20 through the first communicating port 32 and the clean water tank communicating port 21, and the other part of the purified water enters the liquid level box 10 through the second communicating port 31 and the liquid level box communicating port 11. In the specific water production process, when the water level in the liquid level box 10 is lower than the high liquid level, 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 above process. In this process, the booster pump serves as the driving source of the entire cycle.

[0133] In the present application embodiment, combined Figure 3 and Figure 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 mentioned above, 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.

[0134] Furthermore, combined with Figure 4 and the following Fig. 9 The minimum cross-sectional area of ​​the first connecting passage 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 passage Q connecting the liquid level box connecting port 11 with the inner cavity C of the communicating vessel.

[0135] 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 speed of the clean water tank 20 is the same as that of the liquid level box 10, it is easy to cause the liquid level in the clean water tank 20 to be temporarily 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 larger than that of the liquid level box 10, that is, the water outlet speed of the clean water tank 20 with a larger volume is larger than that of the liquid level box 10 with a smaller volume, which can make up for the temporary liquid level height difference caused by the volume difference between the two, so that when the water purifier 100 is in use, the liquid levels of the clean water tank 20 and the liquid level box 10 are kept 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 duplication.

[0136] Furthermore, the communicating vessel 30 is provided with a communicating vessel connecting pipe 34 communicating with the communicating vessel inner cavity C, and the communicating vessel connecting pipe 34 is provided at a position corresponding to the first communicating port 32 .

[0137] The clean water tank 20 is provided with a clean water tank connecting pipe 22, which corresponds to the setting position of the clean water tank connecting port 21, and is connected to the clean water tank inner cavity B of the clean water tank 20; the clean water tank connecting pipe 22 is configured to be partially inserted into the communicating vessel connecting pipe 34 when carried on the supporting member 81 so that the communicating vessel inner cavity C and the clean water tank inner cavity B are connected.

[0138] The portion of the pipe section in the communicating vessel connecting pipe 34 that is not connected to the clean water tank connecting pipe 22 and the clean water tank connecting pipe 22 together define a first connecting channel P. The first connecting channel P has the smallest cross-sectional area at the portion of the pipe section in the communicating vessel connecting pipe 34 that is not connected to the clean water tank connecting pipe 22.

[0139] Furthermore, the communicating vessel 30 is provided with a communicating vessel plug-in tube 341 communicating with the communicating vessel inner cavity C, and the communicating vessel plug-in tube 341 corresponds to the setting position of the second communicating port 31 .

[0140] The liquid level box 10 is provided with a liquid level box plug-in tube 17 , which is in communication with the inner cavity A of the liquid level box; the liquid level box plug-in tube 17 is plugged into the communicating device plug-in tube 341 .

[0141] The portion of the communicating vessel plug-in tube 341 that is not plugged into the liquid level box plug-in tube 17 and the liquid level box plug-in tube 17 together define a second communicating channel Q. The smallest cross-sectional area of ​​the second communicating channel Q is located inside the liquid level box plug-in tube 17 .

[0142] 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 connecting 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 connecting channel Q satisfy:

[0143] S3 / S4=K*S1 / S2

[0144] Among them, K is the resistance coefficient of the fluid in the liquid level box connecting port 11, and the cross-section of the inner cavity B of the water purification tank and the cross-section of the inner cavity A of the liquid level box remain unchanged along the height direction of the water purifier 100.

[0145] In addition, the value of the resistance coefficient K of the fluid will change with the length or shape of the hole depth at the communication port 11 of the liquid level box.

[0146] 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 replication.

[0147] Furthermore, the cross-sectional area S1 of the inner cavity B of the water purification tank along the height direction of the water purifier 100 and the cross-sectional area S3 of the inner cavity A of the liquid level box along the height direction of the water purifier 100 satisfy: S1>S3;

[0148] The bottom wall of the inner cavity B of the clean water tank is arranged flush with the bottom wall of the inner cavity A of the liquid level box.

[0149] In this way, the water level detected by the water level detector in the level box 10 can be made the real water level in the clean water tank 20 .

[0150] Furthermore, the cross-sectional area of ​​the first communication port 32 is greater than the cross-sectional area of ​​the second communication port 31 .

[0151] 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 .

[0152] 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 flow rate of water in the liquid level box 10 is fast, causing the water level in the liquid level box 10 to drop too fast, resulting in the liquid in the liquid level box 10 dropping too fast, and the liquid level is lower than the clean water tank 20, resulting in the water level detected by the water level detector being unable to reflect the real 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 flow rate of water in the liquid level box 10 is slow, and the water level in the liquid level box 10 drops too slowly. Similarly, the water level detected by the water level detector cannot reflect the real water level in the clean water tank 20.

[0153] 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 connecting port 21 is greater than 40mm 2 At the same 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.

[0154] Fig. 9 This is a schematic diagram of the result of the coordination 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.

[0155] In the embodiment of the present application, as mentioned above, a supporting member 81 is further provided on the outer wall of the shell 80 , and the clean water tank 20 is detachably disposed on the supporting member 81 .

[0156] Combination Figure 3 , Figure 8 and Fig. 9 In order to connect the clean water tank 20 with the communicating vessel 30, the first communicating port 32 and the clean water tank communicating port 21 are respectively provided with a communicating vessel check valve 36 and a clean water tank check valve 27.

[0157] Further, as mentioned above, the communicating vessel 30 is provided with a communicating vessel connecting pipe 34 connected to the communicating vessel inner cavity C, and the communicating vessel connecting pipe 34 is arranged at a position corresponding to the first connecting port 32. In specific implementation, at least part of the structure of the communicating vessel 30 is arranged in the shell 80, and the communicating vessel connecting pipe 34 passes through the shell 80 to the outside of the shell 80 and extends to the load-bearing side of the supporting member 81.

[0158] In this way, most of the communicating vessel 30 is accommodated in the shell 80, and only the communicating vessel connecting pipe 34 used to connect with the water purifier 100 is extended out of the shell 80. The purified water tank 20 can be placed on the supporting member 81 outside the shell 80 for easy access by the user.

[0159] Correspondingly, the clean water tank 20 is provided with a clean water tank connecting pipe 22, which is connected to 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 connecting port 21. The communicating vessel check valve 36 is located in the communicating vessel connecting pipe 34, and the clean water tank check valve 27 is arranged in the clean water tank connecting pipe 22.

[0160] 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 inner cavity C of the communicating vessel and the inner cavity B of the clean water tank. 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.

[0161] More specifically, combined with Figure 3 , Figure 8 , a valve seat 362 is provided in the communicating vessel connecting pipe 34, and a valve core 361 of the communicating vessel check valve is elastically connected to the valve seat 362, for example, connected to the valve seat 362 through 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), and the communicating vessel connecting pipe 34 is closed. Of course, when the clean water tank connecting pipe 22 is separated from the communicating vessel 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.

[0162] Exemplarily, the cross-sectional area of ​​the valve core 361 of the communicating vessel check valve is less than or equal to the cross-sectional area of ​​the valve core 271 of the clean water tank check valve.

[0163] In this way, 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 can reliably press against the valve core 361 of the communicating vessel check valve to smoothly open the communicating vessel check valve 36, thereby realizing the water inlet and outlet of the communicating vessel 30 to the clean water tank 20.

[0164] Fig.10 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 the embodiment of the present application; Fig.11 for Fig.10 A local enlarged view of the U; Fig.12 A schematic cross-sectional view of the coordination 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; Fig.13 for Fig.12 A local enlarged view of V. Fig.14 This is a schematic diagram of the structure of the sealing ring 35 and the connecting pipe 34 of the water purifier 100 provided in the embodiment of the present application. Fig.12 and Fig.13 In order to facilitate observation, the structure of the clean water tank check valve 27 is omitted.

[0165] In the present application, refer to Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 A sealing ring 35 is provided on the inner wall of the communicating tube 34, and the axial ends of the sealing ring 35 abut against the inner wall of the communicating tube 34. The first sealing section 353 between the axial ends of the sealing ring 35 and the inner wall of the communicating tube 34 jointly define a water storage chamber F; the clean water tank connecting tube 22 is configured to be inserted into the communicating tube 34 when carried on the supporting member 81 to connect the communicating tube inner chamber C and the clean water tank inner chamber B; and to elastically deform the first sealing section 353 toward its own radial outer side to squeeze the water in the water storage chamber F into the communicating tube 34; and to elastically reset the first sealing section 353 toward its own radial inner side when detached from the communicating tube 34 to absorb the water in the communicating tube 34 into the water storage chamber F.

[0166] In the above scheme, the first sealing section 353 between the two axial ends of the sealing ring 35 and the inner wall of the communicating tube 34 define a water storage chamber F, which has a certain water storage capacity. Since the clean water tank connecting tube 22 can elastically reset toward the radial inner side thereof when it is separated from the communicating tube 34, the water in the communicating tube 34 is adsorbed into the water storage chamber F. Therefore, when the clean water tank 20 is taken by the user and the clean water tank connecting tube 22 is separated from the communicating tube 34, even if water in the communicating tube 30 flows into the communicating tube 34, it will be partially or completely adsorbed by the water storage chamber F, which alleviates the problem of partial water flowing into the communicating tube 34 due to the instantaneous separation of the clean water tank connecting tube 22 and the communicating tube 34 when the clean water tank 20 is taken.

[0167] Continue to refer to Fig.11 and Fig.13 Further, of the two axial ends of the sealing ring 35, the end facing the clean water tank 20 is defined as a first end 351, and the end away from the clean water tank 20 is defined as a second end 352;

[0168] The first end portion 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 installation groove G, and the end of the communicating vessel connecting pipe 34 facing the clean water tank 20 is snapped into the flange portion installation groove G so that the partial structure of the first end portion 351 abuts against the inner wall of the communicating vessel connecting pipe 34.

[0169] 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 .

[0170] 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.

[0171] In this way, the water storage chamber F is formed by providing a water storage groove on the sealing ring 35, which has a relatively simple structure and is easy to process. In addition, it is also convenient for the water purification tank connecting pipe 22 to be inserted into the inner side of the sealing ring 35, and the inner peripheral surface of the sealing ring 35 is pressed radially outward, so that the first sealing section 353 is elastically deformed radially outward, so as to squeeze the water in the water storage chamber F into the communicating vessel connecting pipe 34.

[0172] In the present application, continue to refer to Fig.11The inner circumferential surface of the first sealing section 353 is protrudingly provided with at least two annular interference fit portions 3531, and the at least two interference fit portions 3531 are arranged at intervals along the axial direction of the sealing ring 35, and the at least two interference fit portions 3531 are used for interference fit with the clean water tank connecting pipe 22.

[0173] In this way, when the clean water tank connecting pipe 22 is inserted into the inside of the communicating vessel 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 communicating vessel connecting pipe 34 .

[0174] Exemplarily, along the direction from the first end 351 to the second end 352 , the protrusion height of the interference fit portion 3531 from the inner circumferential surface of the sealing ring 35 gradually decreases.

[0175] 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 insertion process, the clean water tank connecting pipe 22 first contacts the interference fit portion 3531 with a higher protruding height, which can seal the water as soon as possible to avoid water leakage. Continue to insert, the clean water tank connecting pipe 22 cooperates with the interference fit portion 3531 with a lower protruding height, and the interference amount is relatively small, which can reduce the difficulty of inserting the clean water tank connecting pipe 22 and increase the feel of insertion.

[0176] In the present application, refer to Fig.14 There are two interference fit portions 3531 , and a support protrusion 354 is provided between the areas corresponding to the two interference fit portions 3531 on the outer circumferential surface of the sealing ring 35 .

[0177] In this way, when the water clean tank connecting pipe 22 is inserted into the inner side of the sealing ring 35, the interference fit portion 3531 is elastically deformed toward the inner wall of the communicating vessel connecting pipe 34 under the pressure of the water clean 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 area 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 water clean 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 water clean tank connecting pipe 22.

[0178] Furthermore, there are two interference fit parts 3531, and on the outer peripheral surface of the sealing ring 35, the areas corresponding to the two interference fit parts 3531 are respectively provided with avoidance grooves H; the groove depth of the avoidance groove H corresponding to the interference fit part 3531 with a higher protruding height is greater than the groove depth of the avoidance groove H corresponding to the interference fit part 3531 with a lower protruding height.

[0179] In this way, the interference fit portion 3531 with a higher protruding height has a larger avoidance space, and the interference fit portion 3531 with a lower protruding height has a smaller avoidance space. Such a differentiated design makes the capacity of the water storage chamber F as large as possible.

[0180] Combination Figure 3 , Fig. 9 and Fig.13 When the clean water tank connection pipe 22 of the clean water tank 20 is inserted into the communicating vessel connection pipe 34, the valve core 271 of the clean water tank check valve presses against the valve core 361 of the communicating vessel check valve, and the communicating vessel check valve 36 opens, so that the clean water tank cavity B of the clean water tank 20 and the communicating vessel cavity C of the communicating vessel 30 are connected. At this time, the clean water tank connection pipe 22 is inserted into the inner side of the sealing ring 35, and the first sealing section 353 is pushed toward the radial outer side of the sealing ring 35, so that the outer wall of the first sealing section 353 presses against the inner wall of the communicating vessel connection pipe 34, and the water storage cavity F is squeezed flat. 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 communicating vessel connecting pipe 34 on the first sealing section 353 disappears, the sealing ring 35 recovers, and the water storage chamber F returns to its original state. The water that flows out into the communicating vessel connecting pipe 34 will be squeezed into the water storage chamber F due to the atmospheric pressure and temporarily stored in the water storage chamber F.

[0181] Fig.15 This 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.

[0182] In the present application, refer to Fig.15 As mentioned 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, and the clean water tank 20 is supported on the top wall of the supporting member 81.

[0183] 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 place a water cup on the carrier 81, and water outside the water cup and the clean water tank 20 can also be poured into the water collecting chamber D through the water collecting hole 82.

[0184] Furthermore, a water guide portion 83 is provided on the outer wall of the shell 80 , and the carrier 81 is detachably connected to the shell 80 by plugging and fitting with the water guide portion 83 .

[0185] The water guide portion 83 has a guide surface 831 . A guide hole 832 communicating with the water collecting chamber D is formed 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 .

[0186] So, like Fig.15 As shown by the dotted line in FIG. 8 , the water in the communicating vessel connecting pipe 34 can be guided to the guiding hole 832 through the guiding part, and finally flows into the water collecting chamber D. The user can remove the bearing member 81 at regular intervals and clean the water in the water collecting chamber D.

[0187] Furthermore, in order to better guide the 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 the first plane is located within the projection range of the guide surface 831 on the first plane, wherein the first plane is perpendicular to the height direction of the water purifier 100. In this way, when water leaks out of the end of the manifold connecting pipe 34 and falls under the action of gravity, it can be completely caught by the guide surface 831 and collected in the water collection chamber D.

[0188] In a specific implementation, the guide surface 831 is constructed as a conical surface with the guide hole 832 as the center. Such an inclined conical surface has a better guiding effect on water.

[0189] 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.

[0190] 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 gland 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.

[0191] Correspondingly, refer to Fig.10 The outer wall of the clean water tank 20 is configured with a clean water tank installation groove 28, the clean water tank connecting pipe 22 is arranged at the bottom wall of the clean water tank installation groove 28, and an accommodating space I is defined between the outer wall of the clean water tank connecting pipe 22 and the side groove wall of the clean water tank installation groove 28, and the accommodating space I is used to accommodate the gland 37. In this way, the surface of the clean water tank 20 is relatively flat and the structure is relatively beautiful.

[0192] In the present application embodiment, combined Figure 2 and Fig.15 In order to detect whether the clean water tank 20 is located on the supporting member 81 , the water purifier 100 further includes a sensor assembly 86 . The sensor assembly 86 is disposed in the housing 80 and is configured to detect the relative position of the clean water tank 20 and the supporting member 81 .

[0193] The sensor assembly 86 can be set at the inner side of the housing 80, so that the detection end of the sensor assembly 86 passes through the housing 80 to the outside of the housing 80 and extends to the bearing side of the carrier 81. Of course, in order to trigger the sensor assembly 86, a trigger part 861 is provided on the outer wall of the clean water tank 20 at a position corresponding to the detection end; the trigger part 861 is configured to contact the detection end when the clean water tank 20 is carried on the carrier 81, triggering the sensor assembly 86 for detection. In this way, it is convenient to judge whether the clean water tank 20 is located on the carrier 81.

[0194] 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.

[0195] Fig.16 This is a cross-sectional view of the water purification tank 20 in the water purifier 100 provided in the embodiment of the present application. Fig.17 This is a cross-sectional view from another angle of the water purification tank 20 in the water purifier 100 provided in the embodiment of the present application. Fig.18 for Fig.17 A local enlarged view of X, Fig.19 This is a schematic diagram of the exploded structure of the sterilization unit 90 in the water purifier 100 provided in an embodiment of the present application.

[0196] Reference Fig.16 , Fig.17 , Fig.18 , Fig.19 In the embodiment of the present application, the water purifier 100 further includes a sterilization unit 90 to sterilize and disinfect the clean water retained in the clean water tank 20 .

[0197] Specific, combined Fig.10 and Fig.17 The clean water tank 20 is further provided with a first installation groove 29 , and a first installation opening 291 is provided on the bottom wall of the first installation groove 29 .

[0198] Combination Fig.18 and Fig.19The sterilization unit 90 includes a lampshade 91, a lampshade positioning assembly 92 and a sterilization 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 located in the first mounting groove 29, and the head of the lampshade 91 is exposed to the clean water tank 20 through the first mounting opening 291. 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 specific implementation, for example, the first sealing ring 94 is interference-fitted between the first positioning member 93 and the side groove 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 peripheral side of the lampshade 91.

[0199] 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 .

[0200] In the above scheme, the clean water tank 20 is detachably arranged on the bearing member 81 on the outer wall of the housing 80, and the user can take the clean water tank 20 at any time according to the needs. 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 installation 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, so that the lampshade 91 can be installed in the first installation groove 29. Since the head of the lampshade 91 is exposed to the clean water tank 20 through the first installation port 291, and when the clean water tank 20 is carried on the bearing member 81, the germicidal lamp 96 extends into the inner side of the lampshade 91. Therefore, when the clean water tank 20 is carried on the bearing member 81, the light emitted by the germicidal lamp 96 located on the inner side of the lampshade 91 passes through the lampshade 91 and irradiates into the clean water tank 20 to sterilize the water stored in the clean water tank 20.

[0201] 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 outer side and the inner side of the first positioning member 93. The first positioning member 93 is used 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 uses only the 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 small.

[0202] Exemplarily, the lampshade 91 is a light-transmitting structure, for example, the head of the lampshade 91 can extend into the clean water tank 20 through the first mounting opening 291, so that the germicidal lamp 96 can irradiate as much water as possible. The germicidal lamp 96 can be, for example, an ultraviolet germicidal lamp.

[0203] 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 mounting assembly can be further reduced. And the overall strength of the lampshade 91 mounting 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 a rubber member.

[0204] Of course, in order to improve the sealing performance, the number of the 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 the 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.

[0205] Continue to refer to Fig.19 In the case where 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 that at least one annular second mounting groove 932 is provided on the outer peripheral surface of the first positioning member 93, and the first sealing rings 94 are mounted in the second mounting grooves 932 in a one-to-one correspondence. In this way, the first sealing rings 94 can be prevented from moving in the axial direction of the first positioning member 93.

[0206] The inner circumference of the first positioning member 93 is provided with at least one annular stopper 931, and the stopper 931 and the inner circumference of the first positioning member 93 define a half-open annular installation space J, and the second sealing ring 95 is installed in the annular installation 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.

[0207] In the present application embodiment, combined Fig.18 and Fig.19 The lampshade positioning assembly 92 further 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 being separated from the gap between the first positioning member 93 and the lampshade 91.

[0208] As for the connection mode of the sealing member 97 and the first positioning member 93, for example, the sealing member 97 may be provided with a clamping arm 973, and the first positioning member 93 may be provided with a clamping groove 974, and the sealing member 97 and the first positioning member 93 are connected by the clamping cooperation 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 one body.

[0209] 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 being configured to abut against the second sealing ring 95, and the second abutting portion 972 being configured to abut against the end of the lampshade 91 facing the clean water tank 20. In this way, the second sealing ring 95 can be prevented from moving in the axial direction of the first positioning member 93, and the lampshade 91 can be prevented from being separated from the first mounting groove 29.

[0210] Continue to refer to Fig.18 The germicidal lamp 96 includes a germicidal lamp mounting frame 961 and a lamp body 962. The germicidal lamp mounting frame 961 is mounted on the outer wall of the housing 80 at a position corresponding to the first mounting opening 291, and the lamp body 962 is mounted at the end of the germicidal lamp mounting frame 961 facing the clean water tank 20. In this way, the germicidal lamp 96 can be installed at a position corresponding to the lampshade 91.

[0211] Of course, a second mounting opening 8732 is provided on the shell 80 , so that the germicidal lamp mounting bracket 961 can pass through the second mounting opening 8732 and extend out of the shell 80 .

[0212] Continue to refer to Fig.17 The first installation port 291 and the clean water tank connecting port 21 are both located between the top and the bottom of the clean water tank 20, and the first installation port 291 is located higher than the clean water tank connecting port 21. In this way, the sterilization light emitted by the sterilization lamp 96 covers the water in the clean water tank 20 as much as possible.

[0213] Fig. 20 This is a cross-sectional view of another structure of a water purification tank 20 in the water purifier 100 provided in an embodiment of the present application. Fig.21 This is a cross-sectional view from another angle of a water purification tank 20 of another structure in the water purifier 100 provided in an embodiment of the present application, Fig. 22 for Fig.21 A local enlarged view of the Y position.

[0214] Reference Fig. 20 , Fig.21 , Fig. 22 In the above-mentioned solution, it is necessary to open a hole on the front panel 873 and install the sterilization lamp 96, which affects the user's perception. Therefore, it can be considered to set the sterilization unit 90 to a wireless mode.

[0215] In a specific implementation, the sterilization unit 90 may include a lamp holder 98, which is inserted into the first installation opening 291 and sealed with the first installation opening 291. For example, a flange 982 may be provided at the first end of the lamp holder 98, the flange 982 overlaps the edge of the first installation opening 291, and a third sealing ring 981 is provided at the flange 982 and the edge of the first installation opening 291. At this time, the germicidal lamp 96 may be installed at the end of the lamp holder 98 facing the inner side of the clean water tank 20. In this way, the germicidal lamp 96 directly extends into the interior of the clean water tank 20, and compared with the previous solution, the irradiation range in the clean water tank 20 is larger.

[0216] Further, continue to refer to Fig. 22 The sterilization unit 90 further includes a second mounting member 983 sleeved on the lamp holder 98. The second mounting member 983 may be located outside the clean water tank 20, for example, in the first mounting groove 29, and is used to apply a force toward the outside of the clean water tank 20 to the flange portion 982, so that the flange portion 982 presses the third sealing ring 981 against the inner wall of the clean water tank 20. In actual application, the second mounting member 983 may rest on the bottom wall of the first mounting groove 29, and the second mounting member 983 and the lamp holder 98 may be threadedly matched. At this time, the flange portion 982, the first sealing ring 94, and the second mounting member 983 press against the bottom of the first mounting groove 29 from the inner and outer sides of the clean water tank 20, respectively.

[0217] In order to position the germicidal lamp 96, an installation groove is formed at the end of the lamp holder 98 facing the inner side of the clean water tank 20, and the germicidal lamp 96 is sealed and installed in the installation groove.

[0218] In the embodiment of the present application, the sterilization unit 90 further includes a wireless component 99, which includes a wireless transmission unit 991 and a wireless receiving unit 992. The wireless transmission unit 991 is installed 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, and the wireless receiving unit 992 is installed 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 bearing 81, the wireless transmission unit 991 and the wireless receiving unit 992 are arranged relative to each other to supply power to the sterilization lamp 96 through the wireless receiving unit 992.

[0219] Fig.23 A schematic diagram of the structure of a water vapor separator provided in an embodiment of the present application; Fig.24a A schematic cross-sectional view of a water vapor separator provided in an embodiment of the present application; Figure 24b A schematic structural diagram of the water purifier provided in an embodiment of the present application from another angle; Fig.25 for Fig.24a A local enlarged view of the Z position; Fig.26 A schematic structural diagram of a water vapor separator provided in an embodiment of the present application from another angle; Fig. 27 A partial cross-sectional view of a water vapor separator provided in an embodiment of the present application; Fig.28 This is a cross-sectional view of the water vapor separator provided in the embodiment of the present application from another angle. It can be understood that in order to facilitate observation of the internal structure, Fig.26 The diagram shows a state where the primary separation body cover 641 is opened relative to the primary separation body main body 64 .

[0220] In the embodiment of the present application, as mentioned above, the water vapor separator 60 is used to separate the steam in the heated purified water, and a water vapor separation outlet 61 is provided on the water vapor separator 60 , and the water vapor separation outlet 61 forms the water inlet of the water purifier 100 .

[0221] 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 of insufficient outlet water temperature.

[0222] In order to solve this problem, the embodiment of the present application further improves the structure of the water vapor separator 60.

[0223] Specifically, combined Fig.23 , Fig.24a , Fig.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 configured with a primary water vapor separation chamber K and a secondary water vapor separation chamber L that are interconnected.

[0224] The first-level water vapor separation body 63 is provided with a water vapor separation water inlet 631 and a first air outlet 632 which are 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, and the water vapor separation water inlet 631 is used to connect with a hot water supply source.

[0225] 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 outer side of at least a part of the pipe section of the first guide tube 635.

[0226] 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 interconnected. In this way, the water vapor mixture first enters the primary water vapor separation body 63 for a primary water vapor separation, and then enters the secondary water vapor separation body 65 for a secondary water vapor separation, thereby achieving a better water vapor separation effect.

[0227] On the other hand, a water vapor separation water inlet 631 is arranged 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 also provided with a guide wall 66 extending toward the bottom wall 633 of the primary water vapor separation chamber, and the guide wall 66 is arranged on the circumferential outer side of at least part of the pipe section of the first guide pipe 635, so that after the water vapor mixture in the first guide pipe 635 is separated from the first guide pipe 635, it rushes to the top wall 634 of the primary water vapor separation chamber, and the top wall 634 of the primary water vapor separation chamber can break up the water vapor mixture, so that part of the steam in the water vapor mixture is separated from the water flow, and the water flow flows downward along the guide wall 66 into the bottom of the primary water vapor separation chamber K, and the steam is discharged upward from the first outlet 632 out of the primary water vapor separation body 63. As described above, when the water vapor separation effect is good, the amount of steam contained in the water is small, and the water outlet temperature of the water purifier can be set higher to meet the user's water demand.

[0228] The hot water supply source may be, for example, a heater 55, and the water outlet 551 of the heater may be connected to the water vapor separation water inlet 631 through 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.

[0229] 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 primary water vapor separation chamber is lower than the setting height of the top end of the first guide pipe 635 facing the primary water vapor separation chamber K.

[0230] 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 after the water vapor mixture rushing out of the first guide tube 635 is broken up by the top wall 634 of the first-level water vapor separation chamber, the broken up water flow can reliably fall onto the bottom wall 633 of the first-level water vapor separation chamber along the guide wall 66, and will not enter the first guide tube 635 from the top end of the first guide tube 635.

[0231] Further, refer to Fig. 27The guide wall 66 and part of the side wall 636 of the primary water vapor separation chamber define a scattered chamber M, and a portion of the pipe section on the top side of the first guide pipe 635 extends into the scattered chamber M.

[0232] 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 primary water vapor separation chamber K are constructed as an integral piece to facilitate the processing and manufacturing process.

[0233] Combination Fig.24a and Fig. 27 Furthermore, the outer wall of the primary water vapor separation body 63 is provided with a first installation pipe 637 which is coaxial with the first flow guide pipe 635 and communicates with the first flow guide pipe 635. In this way, the water vapor mixture flowing out of the water outlet 551 of the heater is conveniently introduced into the first flow guide pipe 635.

[0234] Furthermore, the first air outlet 632 is disposed on the side wall 636 of the primary water vapor separation chamber, and the side wall 636 of the primary water vapor separation chamber is provided with a second flow guide pipe 638 extending toward the top wall 634 of the primary water vapor separation chamber, and the second flow guide pipe 638 is connected to the first air outlet 632. The flow guide wall 66 extends between the first flow guide pipe 635 and the second flow guide pipe 638, and the top end of the first flow guide pipe 635 and the top end of the second flow guide pipe 638 are separated by the flow guide wall 66.

[0235] In this way, the bottom end of the guide wall 66 is actually set at a height lower than the top end of the second guide tube 638. After the water vapor mixture rushing out of the first guide tube 635 is broken up by the top wall 634 of the primary 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.

[0236] 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 primary water vapor separation chamber K are constructed as an integral piece, which facilitates the processing and manufacturing process.

[0237] In the embodiment of the present application, the outer wall of the primary water vapor separation body 63 is provided with a second installation pipe 639 which is coaxial with the second guide pipe 638 and is in communication with each other. In this way, it is convenient to guide the steam after water vapor separation out of the primary water vapor separation chamber K. In specific implementation, for example, reference can be made to Fig.24a The second installation pipe 639 can be connected to the water vapor separation outlet 62 on the secondary water vapor separation body 65 through the sixth pipeline 106.

[0238] Continue to refer to Fig.26 and Fig. 27Further, the primary water vapor separator 63 includes a primary separator body 64 and a primary separator cover 641 covered on the primary separator body 64, and the guide wall 66 is arranged on the primary separator cover 641. Such an arrangement can facilitate the processing process.

[0239] Combination Fig.24a , Fig. 27 , Fig.28 The primary water vapor separation body 63 is provided with a first connection port 642 communicating with the primary water vapor separation chamber K, and the secondary water vapor separation body 65 is provided with a second connection port 651 communicating with the secondary water vapor separation chamber L. The first connection port 642 is communicated with the second connection port 651.

[0240] The top wall 652 of the secondary water vapor separation chamber is also provided with a third flow guide tube 655 extending toward the bottom wall 653 of the secondary water vapor separation chamber, and the third flow guide tube 655 is connected to the second connection port 651. The bottom wall 653 of the secondary water vapor separation chamber is provided with a stop wall 654 extending toward the top wall 652 of the secondary water vapor separation chamber, and the stop wall 654 is blocked between the circumferential outer side of the third flow guide tube 655 and the water vapor separation outlet 61.

[0241] A third flow guide tube 655 extending toward the bottom wall 653 of the secondary water vapor separation chamber is also 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 downward onto the bottom wall 653 of the secondary water vapor separation chamber and is dispersed again, so that part of the steam mixed in the water flow is separated from the water flow. A stop wall 654 extending toward the top wall of the secondary water vapor separation chamber is provided on the bottom wall 653 of the secondary water vapor separation chamber. The stop wall 654 is provided around the third flow guide tube 655. Toward the outside and between the water vapor separation outlet 61, in this way, the water flow that has been dispersed and separated on the bottom wall 653 of the secondary water vapor separation chamber hits the stop wall 654 in the process of flowing toward the water vapor separation outlet 61, and is dispersed again, and water vapor separation is performed. The separated steam flows out of the secondary water vapor separation chamber L from the water vapor separation outlet 62. The water flow dispersed again by the stop wall 654 has 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 is separated twice again, and is used in combination with the primary water vapor separation body 63, so that the water vapor separation effect of the hot water reaches a better degree.

[0242] Combination Fig.24a , Fig.28 Furthermore, 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.

[0243] The bottom end of the third flow guide pipe 655 is extended into the retention tank N, that is, the height of the bottom end of the third flow guide pipe 655 is lower than the height of the notch edge of the retention tank N. In this way, when the water intake stops, the water flowing out of the primary water vapor separation chamber K will rush out of the third flow guide pipe 655 due to the inertia of the water flow and the adhesion characteristics of the water, so that the water level of the third flow guide pipe 655 is lower than the water level in the retention tank N (full of water). As time goes by, the water in the third flow guide pipe 655 gradually becomes stable, and part of the water in the retention tank N returns to the third flow guide pipe 655, so that the water level in the third flow guide pipe 655 is level with the water level in the retention tank N, thereby the water level in the retention tank N is reduced. The water below the edge of the groove 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 65, the water level in the retention groove N and the third guide tube 655 will rise accordingly. However, due to the viscosity of water, it will adhere to the side groove wall of the retention groove N, that is, the water in the retention groove 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 water when stopping water intake is achieved, which effectively improves the problem of water leakage at the water intake of the water purifier 100.

[0244] In the related art, air easily enters the inner cavity of the water vapor separator 60 from the water vapor separation outlet 61, and in the long run, it is easy to breed bacteria, and because the inner cavity is an area that cannot be cleaned by the user. In view of this, through the setting of the retention groove N, after stopping the water intake, the bottom end of the third guide pipe 655 extends into the retention groove N, playing a liquid seal role, so that the outside air can be prevented from entering the inner cavity of the water vapor separator 60, especially the primary water vapor separation body 63, which can inhibit the growth of bacteria and make the water outlet of the water vapor separator 60 cleaner and more hygienic.

[0245] In some embodiments, the stop wall 654 and a portion of the side wall 656 of the secondary water vapor separation chamber define the above-mentioned retention groove N. Compared with the groove on the bottom wall 653 of the secondary water vapor separation chamber, this configuration can make the volume of the secondary water vapor separation body 65 smaller.

[0246] Combination Fig.23 and Fig.24a Furthermore, a first matching tube 657 communicating with the first connecting port 642 is provided on the outer wall of the first-level water vapor separation body 63, and a first matching slot 658 communicating with the second connecting port 651 is provided on the second-level 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.

[0247] 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 sleeved on the outer periphery of the first mating tube 657 and clamped between the first mating tube 657 and the first mating slot 658.

[0248] In this way, the primary water vapor separation body 63 and the secondary water vapor separation body 65 are plugged and matched, so that the two are matched more firmly. Of course, it can be understood that, referring to Fig.23 The primary water vapor separation body 63 and the secondary water vapor separation body 65 can also be fixedly connected by a fastener 643, so that the connection between the two is more secure. A plurality of positioning ribs 659 arranged at intervals along the circumferential direction can also be provided on the outer peripheral wall of the first matching tube 657. The positioning ribs 659 abut against the notch of the first matching slot 658 to assist in positioning the first matching tube 657 and the first matching slot 658.

[0249] Combination Fig.23 and Fig.24a Furthermore, the secondary water vapor separation body 65 includes a secondary water vapor separation main body 671 and a secondary water vapor separation cover body 673 covered on the secondary water vapor separation main body 671, the first matching slot 658 is arranged on the top end side of the secondary water vapor separation cover body 673, and the third guide tube 655 is arranged on the bottom end side of the secondary water vapor separation cover body 673 and is connected to the first matching slot 658.

[0250] Thus, after the first matching pipe 657 is inserted into the first matching slot 658, water flowing out of the first matching pipe 657 can directly enter the third flow guide pipe 655. In a specific implementation, the first matching pipe 657 and the third flow guide pipe 655 can be coaxially arranged.

[0251] Further, the water vapor separation outlet 61 is arranged on the bottom wall 653 of the secondary water vapor separation chamber, and the bottom wall 653 of the secondary water vapor separation chamber is configured as an inclined wall structure inclined toward the water vapor separation outlet 61. In this way, the water flowing out of the retention tank N can flow into the water vapor separation outlet 61 relatively easily along the inclined wall.

[0252] Combination Fig.24a and Fig. 27 , further, the water vapor separation outlet 62 is arranged 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;

[0253] A fourth flow conduit 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 conduit 672 is connected to the water vapor separation outlet 62, and a distance is provided between the top end of the fourth flow conduit 672 and the top wall 652 of the secondary water vapor separation chamber.

[0254] 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, can enter the fourth flow tube 672 from the top end of the fourth flow tube 672, and flow out of the secondary water vapor separation chamber L from the water vapor separation outlet 62.

[0255] 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 .

[0256] 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 air guide tube 672 , and the top end of the fourth air guide tube 672 extends into the avoidance recess O.

[0257] In this way, even if the length of the fourth air guide pipe 672 is longer, the external contour size of the secondary water vapor separation body 65 will not be increased.

[0258] Further, the water vapor separation air outlet 62 is located between the water vapor separation water outlet 61 and the second connecting port 651 , and the first connecting port 642 corresponds to the position of the second connecting port 651 .

[0259] Furthermore, the water vapor separation water outlet 61 , the water vapor separation air outlet 62 and the first connecting port 642 are arranged in a row.

[0260] Reference Figure 24b As mentioned above, the outer wall of the housing 80 is provided with a bearing member 81, and a water collecting box 85 is formed on the bearing member 81. When taking water, the user can place the water taking container on the water collecting box 85 to take water from the position of the water vapor separation outlet 61. The water vapor separator 60, especially the water vapor separation outlet 61 and the water vapor separation air outlet 62, needs to be located above the bearing member 81 (water collecting box 85) and also corresponds to the position of the bearing member 81.

[0261] 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.

[0262] Furthermore, the first connection port 642 is arranged on the bottom wall 633 of the primary water vapor separation chamber, and the bottom wall 633 of the primary water vapor separation chamber is constructed as an inclined structure inclined toward the first connection port 642. In this way, the water flowing downward from the guide wall 66 can flow out of the primary water vapor separation chamber K from the first connection port 642 more easily. As mentioned above, the water vapor separation water inlet 631 and the first connection port 642 are both located on the bottom wall 633 of the primary water vapor separation chamber, but the water vapor separation water inlet 631 is arranged at a higher position than the first connection port 642, so that the fluid flowing out from the first guide pipe 635 can be more easily guided from the bottom wall 633 of the primary water vapor separation chamber to the first connection port 642.

[0263] In addition, as mentioned above, the water vapor separation outlet 62 can be communicated with the interior of the filter housing 42, so that 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 implementation, part of the structure of the water vapor separator 60 can be arranged in the housing 80, and the water vapor separation water outlet 61 and the water vapor separation outlet 62 are both arranged outside the housing 80. Such an arrangement facilitates the steam discharged from the water vapor separation outlet 62 to escape to the outside of the housing.

[0264] 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.

[0265] 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 water discharge.

[0266] Refer to the following Fig.28 The working process of the water-steam separator 60 during the water-cut operation is described.

[0267] exist Fig.28 In the present invention, the water-cut-off process of the water-steam separator is divided into six states.

[0268] State (a) is the water level state during water production.

[0269] State (b) corresponds to the moment 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 water flow inertia and the adhesion characteristics of water, so that the water level of the third flow conduit 655 is lower than the water level in the retention tank N.

[0270] State (c) is that as time goes by, the water in the third flow conduit 655 gradually becomes stable, and part of the water in the retention groove N returns to the third flow conduit 655, so that the water level in the third flow conduit 655 is level with the water level in the retention groove N, so that the water level in the retention groove N is lower than the top end of the stop wall 654.

[0271] In state (d), 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 groove N and the third guide tube 655 will rise accordingly. However, due to the viscosity of water, it will adhere to the side of the stop wall 654 close to the retention groove N, that is, the water in the retention groove N will not exceed the stop wall 654. 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.

[0272] State (e) corresponds to a schematic diagram in which the stop wall 654 blocks the dripping water in the retention groove.

[0273] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0274] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
