Description

Technical Field

[0001] This invention relates to the field of water purification technology, and in particular to a water purifier. Background Technology

[0002] As people's living standards improve, more and more people are pursuing a high-quality life, and water purifiers are undoubtedly one of the best choices. Water purifiers in related technologies include filters, connectors, level boxes, purified water tanks, heaters, and water pumps. During water production, the filtered water is distributed to the level box and purified water tank via the connector. When a user draws water, the water pump draws water from the level box and purified water tank through the connector to the heater, and then supplies water to the user. However, during water production, air from the connectors and filters can enter the subsequent water circuit, including the heater. This causes air to be mixed with the water when it comes out of the water purifier's outlet. When using cold water, the water flow is unstable and slow; when using hot water, the air mixed in with the hot water causes steaming, resulting in poor water quality from the purifier.

[0089] The water purifier 100 of this application is described below with reference to the accompanying drawings.

[0090] Figure 1 This is a schematic diagram of the structure of the water purifier 100 provided in the embodiments of this application; Figure 2 This is an exploded structural diagram of the water purifier 100 provided in an embodiment of this application; Figure 3 This is an exploded structural diagram of the water purifier 100 provided in an embodiment of this application from another angle. Figure 4 This is a cross-sectional view of the level box 10 in the water purifier 100 provided in the embodiment of this application.

[0091] Reference Figure 1 , Figure 2 , Figure 3 This application provides a water purifier 100 for purifying water from a source to be filtered.

[0092] The water purifier 100 includes: a housing 80, a filter 40, a connector 30, a purified water tank 20, a level box 10, a water pump 50, a heater 55, and a water vapor separator 60. The filter 40 is connected to the inner cavity C of the connector 30. The connector 30 is connected to both the purified water tank 20 and the level box 10. The water pump 50 is connected to both the inner cavity C of the connector 30 and the heater 55, thus allowing the water pump 50 to pump water from the level box 10 and the purified water tank 20 to the heater 55 via the connector 30. The heater 55 is connected to the water vapor separator 60. It should be noted that the connector 30 and the purified water tank 20 are detachably connected.

[0093] With this setup, when a user draws water, the water pump 50 draws water from the connector 30. Water from the level box 10 and the clean water tank 20 simultaneously flows through the connector 30 into the water pump 50. The water from the water pump 50 flows into the heater 55, is heated by the heater 55, and then flows into the water vapor separator 60 and out of the water vapor separator 60.

[0094] The filter 40 is used to connect to the water source to be purified, so as to filter the water source. The purified water tank 20 is used to store the filtered purified water. The level box 10 is equipped with a water level sensor 12. The purified water tank 20 is connected to the level box 10 through a communicating vessel 30. Both the purified water tank 20 and the level box 10 are open to the atmosphere. According to the principle of communicating vessels, the water level in the level box 10 can reflect the water level in the purified water tank 20.

[0095] 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 intake of the water purifier 100.

[0096] Reference Figure 2 , Figure 3 When a user needs to obtain purified water, the water pump 50 operates, simultaneously drawing water from the purified water tank 20 and the liquid level box 10 through the connector 30 into the heater 55. After passing through the heater 55, the water continues to pass through the water vapor separator 60 and is then taken out from the water vapor separator outlet 61.

[0097] When the water level in the level box 10 is lower than the high level below, the filter 40 works to purify the water source to be purified. The purified water enters the level box 10 and the clean water tank 20 through the connector 30.

[0098] The following is a detailed description of each part of the water purifier 100 with reference to the accompanying drawings.

[0099] Reference Figure 1 and Figure 2 The housing 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, top cover 871, base 872, and front panel 873 together enclose a receiving cavity, in which the aforementioned filter 40, communicating vessel 30, liquid level box 10, water pump 50, and heater 55 are disposed. The rear panel 870 and front panel 873 surround the side of the base 872, forming the main body of the housing 80, and the top cover 871 covers the front panel 873 and rear panel 870.

[0100] The outer wall of the housing 80 is also provided with a support member 81, and the water tank 20 is detachably mounted on the support member 81.

[0101] The support member 81 is configured as a water collection box 85, which is detachably disposed on the outside of the housing 80, and the top wall of the water collection box 85 is provided with a water collection hole 82 communicating with the interior. The clean water tank 20 is supported on the top wall of the water collection box 85.

[0102] Thus, the water tank 20 is detachably mounted on the outside of the housing 80, allowing users to directly remove the water tank 20 to draw water when a large amount is needed. Additionally, the water tank 20 can be easily removed for cleaning and other maintenance operations.

[0103] In addition, combined Figure 1 and Figure 2 A portion of the structure of the water vapor separator 60 penetrates the housing 80 and extends to the outside of the housing 80, with the water vapor separator outlet 61 located on the portion of the water vapor separator 60 extending to the outside of the housing 80. This facilitates the user in drawing water from the water vapor separator outlet 61 outside the housing 80. For example, a clearance opening 8731 can be formed on the front panel 873, through which the water vapor separator outlet 61 extends to the outside of the housing 80.

[0104] In the embodiments of this application, reference is made to Figure 4 The water level sensor 12 is configured as a float sensor, and includes a first float 121 and a second float 122. Inside the liquid level box 10, along the height direction of the liquid level box 10, are arranged sequentially a first upper baffle 123, a first lower baffle 124, a second upper baffle 125, and a second lower baffle 126. 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.

[0105] The water level sensor 12 is configured to detect the liquid level in the liquid level box 10 (also referred to as the water level when the liquid level box contains water), and to determine that the liquid level is high when the first float 121 abuts against the first upper baffle 123, and to determine that the liquid level is low when the second float 122 abuts against the second lower baffle 126.

[0106] With this setup, the float travels are relatively short whether detecting high or low liquid levels. Compared to a solution with only one float, this avoids situations where the float travels too long at different liquid levels, making it prone to getting stuck and causing inaccurate detection results or float malfunction.

[0107] In this embodiment of the application, the water purifier 100 also includes a controller (not shown). The controller is electrically connected to the water level sensor 12 and the booster pump. The controller is configured to control the booster pump to stop working and thus stop water production when the liquid level in the liquid level box 10 is at a high level; to control the booster pump to start working and produce water when the liquid level in the liquid level box 10 is lower than the high level; and to control the water pump 50 to stop working and stop water output when the liquid level in the liquid level box 10 is at a low level.

[0108] In this embodiment of the application, the water purifier 100 also includes an exhaust component 70.

[0109] The exhaust component 70 is configured with a first chamber E that communicates with the atmosphere, and the first chamber E is connected to the filter outlet of the filter 40 (not shown).

[0110] As previously described, the communicating vessel 30 has an inner cavity C, which is connected to the purified water tank 20, the liquid level box 10, and the first chamber E. For example, water filtered by the filter 40 can be sequentially input into the exhaust vent 70 and the communicating vessel 30, and then flow into the liquid level box 10 and the purified water tank 20 through the inner cavity C. Furthermore, the communicating vessel 30 is also connected to the filter outlet on the filter body 43 (described later) and the water inlet of the water purifier.

[0111] By setting up the venting device 70, the air in the communicating vessel 30 and the air entering the filter 40 during the initial water production can be discharged through the venting device 70. In other words, the water filtered from the filter 40 is directly vented through the venting device 70, reducing the amount of gas entering the communicating vessel 30. This not only solves the problem of hot water jetting, but also solves the problem of unstable water form and slow water output speed at the water inlet of the water purifier 100, and further facilitates the smooth flow of water.

[0112] Continue to refer to Figure 3 The liquid level box 10 is provided with an outlet 13 that communicates with the atmosphere; the exhaust component 70 is provided on the liquid level box 10, and the first chamber E is connected to the inner cavity A of the liquid level box 10 so as to communicate with the atmosphere through the outlet 13. In this way, the liquid level box 10 and the exhaust component 70 can be installed as a single unit, which can reduce the number of parts and save installation steps.

[0113] Furthermore, referring to Figure 5 An exhaust vent 70 is disposed on the outer wall of the liquid level box 10. Both the exhaust vent 70 and the liquid level box 10 have interconnecting openings 14 on their facing side walls to allow the first chamber E to communicate with the inner cavity A of the liquid level box. The first chamber E communicates with the inner cavity A of the liquid level box, while the liquid level box 10 is connected to the atmosphere. Thus, the first chamber E of the exhaust vent 70 is connected to the atmosphere through the inner cavity A of the liquid level box.

[0114] Regarding the connection methods between the various components, combined with Figure 3 , Figure 4 , Figure 5 For example, the exhaust component 70 may be provided with an exhaust component inlet 72 and an exhaust component outlet 73, and the communicating vessel 30 may be provided with a communicating vessel inlet 33 that communicates with the inner cavity C of the communicating vessel. The exhaust component inlet 72 is connected to the filter outlet through the first pipe 101, and the exhaust component outlet 73 is connected to the communicating vessel inlet 33 of the communicating vessel 30 through the second pipe 102.

[0115] The connection port 14 on both the vent 70 and the liquid level box 10 is positioned at a higher height relative to the bottom wall of the liquid level box 10 than the liquid inlet 72 of the vent 70. This prevents water entering the vent 70 from the liquid inlet 72 from entering the liquid level box 10 through the connection port 14.

[0116] Reference Figure 3 Furthermore, the inlet 33 of the communicating vessel is connected to the outlet of the filter 40 through the exhaust 70. The diameter of the inlet 33 of the communicating vessel is greater than 6 mm, and the inner diameter of the second pipe 102 is greater than 6 mm.

[0117] When the diameter of the inlet 33 of the communicating vessel or the inner diameter of the second pipe 102 connected to the inlet 33 of the communicating vessel is less than 6mm, the process of air entering the exhaust 70 through the second pipe 102 in the communicating vessel 30 is obstructed, which can easily lead to poor exhaust. This makes it difficult for water to enter the communicating vessel 30 from the exhaust 70 to proceed smoothly and stably. As a result, water accumulated in the exhaust 70 may directly enter the liquid level box 10 from the connecting port 14, causing the water level in the liquid level box 10 to be too high and affecting the judgment of the water level in the clean water tank 20.

[0118] Figure 6 This is a schematic diagram of the structure of the filter 40 in the water purifier 100 provided in the embodiments of this application.

[0119] Reference Figure 6 The filter 40 includes a filter housing 42 and a filter body 43. The filter housing 42 has a filter cavity 44 with one end open (communicating with the atmosphere). The filter body 43 is disposed in the filter cavity 44. The air outlet 13 provided on the liquid level box 10 is connected to the inside of the filter housing 42 of the filter 40.

[0120] The filter housing 42, i.e., the filter cavity 44, is connected to the atmosphere, and the air outlet 13 is connected to the filter housing 42 of the filter 40, thereby allowing the liquid level box 10 to be connected to the atmosphere. In addition, the purified water tank 20 is also connected to the atmosphere. Therefore, when the water purifier 100 draws water from the liquid level box 10 and the purified water tank 20 through the communicating vessel 30, or when the water filtered by the filter 40 enters the liquid level box 10 and the purified water tank 20 through the communicating vessel 30, according to the principle of communicating vessels, the water level in the liquid level box 10 and the water level in the purified water tank 20 can be kept approximately equal, so that the water level in the liquid level box 10 can accurately reflect the water level in the purified water tank 20.

[0121] The liquid level box 10 (air outlet 13) is connected to the interior of the filter 40 (that is, the filter cavity 44 inside the filter housing 42) through the third pipe 103.

[0122] Furthermore, the liquid level box 10 includes a box body 15 and a box cover 16 with a sealing cover on the box body 15, and an air outlet 13 is opened on the box cover 16.

[0123] In a specific implementation, as mentioned above, the filter housing 42 is provided with a filter housing air inlet 41 that communicates with the filter inner cavity, and the two ends of the third pipe 103 are respectively connected to the air outlet 13 and the filter housing air inlet 41, so that the liquid level box 10 is in communication with the atmosphere.

[0124] It is understandable that the filter cavity must have 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 to the filter cavity of the filter 40 through the third pipe 103, the overall appearance of the water purifier 100 is more aesthetically pleasing without adding new openings to the housing 80 of the water purifier 100.

[0125] For example, the filter housing 42 is provided with a filter extension tube 421 that communicates with the interior of the filter housing 42 through the air inlet 41. The cover 16 is provided with a liquid level box extension tube 161 at the position corresponding to the air outlet 13. The two ends of the third pipe 103 are respectively connected to the filter extension tube 421 and the liquid level box extension tube 161. This arrangement facilitates the connection of the two ends of the third pipe 103 to the filter housing 42 and the liquid level box 10.

[0126] Furthermore, the housing 15 is provided with a first mounting portion 162, and the filter housing 42 is provided with a second mounting portion 422. The first mounting portion 162 is connected to the second mounting portion 422 to connect the liquid level box 10 to the filter 40. It is understood that there can be multiple first mounting portions 162 and second mounting portions 422. For example, some of the first mounting portions 162 can be provided on the housing 15, and the second mounting portions 422 corresponding to these first mounting portions 162 can be provided on the filter housing at the positions corresponding to the first mounting portions 162.

[0127] 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 from the level box 10 and the clean water tank 20 to the heater 55 through the communicating vessel 30.

[0128] The water vapor separator 60 includes a water vapor separation outlet 62 and the aforementioned water vapor separation outlet 61. The water vapor separation outlet 62 is connected to the interior of the filter housing 42. In this way, the steam discharged from the water vapor separation outlet 62 can be discharged into the atmosphere through the filter housing 42.

[0129] In this embodiment, the filter 40 includes three stages of filtration to achieve better filtration results.

[0130] In a specific implementation, the filter body 43 includes a primary filter 431, a secondary filter 432, and a tertiary filter 433 connected in sequence. The filter cavity 44 includes a primary filter cavity 441, a secondary filter cavity 442, and a tertiary filter cavity 443 that are connected in series. The primary filter 431 is housed in the primary filter cavity 441, the secondary filter 432 is housed in the secondary filter cavity 442, and the tertiary filter 433 is housed in the tertiary filter cavity 443. The air outlet 13 is connected to the primary filter cavity 441.

[0131] By setting the filter body 43 as a first-stage filter 431, a second-stage filter 432, and a third-stage filter 433 connected in sequence, the filtration effect can be improved.

[0132] Furthermore, the water purifier 100 also includes a booster pump, which is used to draw water to be purified into the filter body 43, where the water is purified. By setting up a booster pump as the power source for the purifier to produce water, it can be used for different types of water sources, such as water tanks used in daily life, in addition to tap water sources with a certain water pressure.

[0133] In this embodiment of the application, combined with Figure 3 , Figure 4 As mentioned above, the water pump 50 is connected to the connector 30 and the heater 55 respectively, and is used to pump water from the liquid level box 10 and the clean water tank 20 to the heater 55 through the connector 30. The water vapor separator 60 is connected to the heater 55 and is used to separate water vapor from the water heated by the heater 55.

[0134] With this setup, when a user draws water, the water pump 50 draws water from the connector 30, and the water in the level box 10 and the clean water tank 20 flows into the water pump 50 at the same time. The water from the water pump 50 flows into the heater 55, and after passing through the heater 55, it flows into the water vapor separator 60 and then flows out from the water vapor separator 60.

[0135] Continue to refer to Figure 6 Furthermore, the water vapor separator outlet 62 is connected to the third pipe 103 via the fourth pipe 104. In this way, the steam separated by the water vapor separator outlet 62 can also be discharged into the atmosphere through the filter housing 42. This also reduces the number of pipes, making the structure more compact.

[0136] Regarding the connection between the water purification tank 20 and the atmosphere, for example, you can refer to... Figure 4 The purified water tank 20 includes a tank body 25 and a tank lid 26 that can be opened and closed on the tank body 25. A gap is provided between the tank body 25 and the tank lid 26 to allow the purified water tank 20 to communicate with the atmosphere. Thus, when a user needs a large amount of water, the water can be taken out by opening the tank lid 26 and turning it upside down.

[0137] Furthermore, the water vapor separation outlet 62 is located at the top of the water vapor separator 60, and the third pipe 103 and the fourth pipe 104 are located on one side of the top of the liquid level box 10 and the water vapor separator 60.

[0138] This allows the lengths of the third pipe 103 and the fourth pipe 104 to be set shorter, and combined with the characteristic of water vapor rising, it allows water vapor to be discharged more smoothly.

[0139] Figure 7 This is a cross-sectional schematic diagram of the water purifier 100 provided in the embodiment of this application.

[0140] In this embodiment of the application, as described above, the communicating vessel 30 is connected to both the liquid level box 10 and the clean water tank 20. In specific implementation, it is combined with... Figure 3 and Figure 7 The liquid level box 10 is provided with a liquid level box connection port 11, and the purified water tank 20 is provided with a purified water tank connection port 21. The communicating vessel 30 is also provided with a second connection port 31 and a first connection port 32; the second connection port 31 is connected to the liquid level box connection port 11, and the first connection port 32 is connected to the purified water tank connection port 21. In this way, the communicating vessel 30 is connected to both the liquid level box 10 and the purified water tank 20.

[0141] Furthermore, referring to Figure 3 , Figure 4 The communicating vessel 30 is also provided with a communicating vessel outlet 38, which is connected to the water inlet of the water purifier 100; the liquid level box communicating port 11 is set at a higher height relative to the bottom of the water purifier 100 than the communicating vessel outlet 38.

[0142] With this configuration, the liquid in the liquid level box 10 can flow out of the communicating vessel 30 relatively smoothly through the liquid outlet 38, thereby avoiding the situation where the liquid level box 10 is not flowing smoothly and water accumulates in the liquid level box 10, resulting in the clean water supplied to the water intake being water mixed with the accumulated water.

[0143] In a specific implementation, the communicating vessel 30 is provided with an extension tube 39, which extends from the outside of the communicating vessel 30 (e.g., the top side) through the wall of the communicating vessel 30 and extends to the bottom of the communicating vessel cavity C. The end of the extension tube 39 located in the communicating vessel cavity C forms the communicating vessel outlet 38.

[0144] Of course, the connection between the water pump 50 and the communicating vessel 30 is achieved through a pipe connecting the outlet 38 of the communicating vessel to the inlet of the water pump 50. The outlet of the water pump 50 is also connected to the heater 55 through another pipe to deliver the clean water in the communicating vessel 30 to the heater 55. The water pump 50 can be connected to the outer wall of the venting component 70 by fasteners such as screws.

[0145] Furthermore, the height of the inlet 33 of the communicating vessel relative to the bottom of the water purifier 100 is higher than the height of the level box communicating port 11, the water tank communicating port 21, and the outlet 38 of the communicating vessel. The inlet 33 of the communicating vessel can be located at the very top of the communicating vessel 30. This allows the purified water entering the communicating vessel 30 from the inlet 33 to smoothly enter the level box 10 and the water tank 20.

[0146] Figure 8 This is a schematic diagram of another structure of the communicating vessel 30 in the water purifier 100 provided in the embodiments of this application.

[0147] Reference Figure 8 Since the water purifier 100 needs to pass through the communicating vessel 30 for both water production and intake, air cannot be easily discharged during the water production process due to the small size of the communicating vessel 30. It is advisable to connect the inner cavity C of the communicating vessel to the filter outlet of the filter 40. For example, the filter outlet of the filter 40 can be connected to the communicating vessel inlet 33 via a pipe (not shown). In this case, the communicating vessel inlet 33 can be connected to the venting device 70 simultaneously, or only to the filter outlet without connecting to the venting device 70.

[0148] Furthermore, an exhaust vent 701 connected to the atmosphere is provided on the communicating vessel 30. The exhaust vent 701 is connected to the inner cavity C of the communicating vessel, which facilitates the smooth discharge of air from the communicating vessel 30 during the water purification and water intake processes of the water purifier 100, ensuring smooth water flow and maintaining a constant water level in the water tank 20 and the float box. When the inlet 33 of the communicating vessel is only connected to the outlet of the filter and not to the exhaust vent 70, the water filtered by the filter 40 does not pass through the exhaust vent 70 but enters the inner cavity C of the communicating vessel directly from the inlet 33 and is vented using the exhaust vent 701.

[0149] In a specific implementation, the top of the communicating vessel 30 is provided with an exhaust port 301 that communicates with the inner cavity C of the communicating vessel, and the exhaust port 301 forms an exhaust section 701. Of course, in order to facilitate the smooth discharge of air from the communicating vessel 30, an exhaust pipe 302 is also provided on the exhaust port 301, and the exhaust pipe 302 extends along the height direction of the water purifier 100.

[0150] It should be noted that in another possible implementation, the inlet 33 of the communicating vessel can be connected to the outlet of the filter of the vent 70 at the same time. The water in the filter 40 can enter the communicating vessel 30 in part through the vent 70, or it can enter the communicating vessel 30 directly through the pipe connected to the inlet 33 of the communicating vessel. At this time, the vent can be vented at the same time through the vent 70 and the vent 701.

[0151] The following is combined with Figure 3 , Figure 7This describes the working process of the water purifier 100 in the embodiments of this application.

[0152] When users need to collect purified water, such as Figure 3 As shown by the dashed arrow, when the water pump 50 is working, the purified water in the purified water tank 20 enters the inner cavity C of the communicating vessel through the purified water tank connection port 21 and the first connection port 32. The purified water in the liquid level box 10 enters the inner cavity C of the communicating vessel through the liquid level box connection port 11 and the second connection port 31. Driven by the water pump 50, the purified water in the inner cavity C of the communicating vessel enters the water pump 50 through the liquid outlet 38 of the communicating vessel and then enters the heater 55 connected to the water pump 50. When the purified water enters the heater 55, the heater 55 is working and can heat the purified water. When the heater 55 is not working, the purified water will not be heated. The water entering the heater 55 eventually enters the water vapor separator 60. After the heated purified water undergoes water vapor separation in the water vapor separator 60, the purified water flows out from the water vapor separator outlet 61. If the purified water is not heated in the heater 55, it also flows out directly through the water vapor separator outlet 61. In this process, the water pump 50 serves as the driving source for the entire cycle.

[0153] During the water production process, combined with Figure 3 , Figure 4 Referring to the solid arrow, the booster pump (not shown) operates, the filter 40 purifies the water source, and the purified water is transported through the first pipe 101 to the first chamber E of the exhaust vent 70, and then through the exhaust outlet 73, the second pipe 102, and the inlet 33 of the communicating vessel into the inner cavity C of the communicating vessel. Part of the purified water entering the inner cavity C of the communicating vessel passes through the first connecting port 32 and the purified water tank connecting port 21 into the purified water tank 20, while the other part passes through the second connecting port 31 and the level box connecting port 11 into the level box 10. Specifically, during the water production process, when the water level in the level box 10 is lower than the high level, the filter 40 operates to purify the water source, and the purified water, after the above process, enters the level box 10 and the purified water tank 20 respectively. In this process, the booster pump serves as the driving source for the entire cycle.

[0154] In this embodiment of the application, combined with Figure 3 and Figure 7 The volume of the inner cavity B of the water purification tank 20 is greater than the volume of the inner 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 water purification tank 20 through the inner cavity C of the communicating vessel.

[0155] Furthermore, combined with Figure 4 and the following Figure 9 The minimum cross-sectional area of ​​the first connecting channel P, which connects the water tank connection port 21 to the inner cavity C of the communicating vessel, is greater than the minimum cross-sectional area of ​​the second connecting channel Q, which connects the liquid level box connection port 11 to the inner cavity C of the communicating vessel.

[0156] Because the volume of the inner cavity B of the water purification tank 20 is larger than the volume of the inner cavity A of the level box 10, if the inflow and outflow rates of the water purification tank 20 and the level box 10 are the same, the liquid level in the water purification tank 20 may temporarily be higher than that in the level box 10 when the water purifier 100 is in use. In this 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 inflow and outflow rate of the water purification tank 20 per unit time is greater than that of the level box 10 per unit time. That is, the outflow rate of the larger-volume water purification tank 20 is greater than that of the smaller-volume level box 10, which can compensate for the temporary difference in liquid level caused by the difference in volume. This ensures that the liquid levels of the water purification tank 20 and the level box 10 are kept consistent in real time when the water purifier 100 is in use, and that the water level detected by the water level detector in the level box 10 always accurately reflects the water level in the water purification tank 20, thus avoiding the occurrence of reverse water level.

[0157] Furthermore, the communicating vessel 30 is provided with a communicating vessel connecting pipe 34 that communicates with the inner cavity C of the communicating vessel, and the communicating vessel connecting pipe 34 corresponds to the setting position of the first communicating port 32.

[0158] The water purification tank 20 is provided with a water purification tank connecting pipe 22, which corresponds to the location of the water purification tank communication port 21. The water purification tank connecting pipe 22 is connected to the inner cavity B of the water purification tank 20. The water purification tank connecting pipe 22 is configured to be partially inserted into the communicating vessel connecting pipe 34 when it is supported on the support member 81 so that the inner cavity C of the communicating vessel and the inner cavity B of the water purification tank are connected.

[0159] The portion of the connecting pipe 34 that is not connected to the water tank connecting pipe 22, together with the water tank connecting pipe 22, defines the first connecting channel P. The point with the smallest cross-sectional area of ​​the first connecting channel P is located on the portion of the connecting pipe 34 that is not connected to the water tank connecting pipe 22.

[0160] Furthermore, the communicating vessel 30 is provided with a communicating vessel insertion pipe 341 that communicates with the inner cavity C of the communicating vessel, and the communicating vessel insertion pipe 341 corresponds to the setting position of the second communicating port 31.

[0161] The liquid level box 10 is provided with a liquid level box insertion pipe 17, which is connected to the inner cavity A of the liquid level box; the liquid level box insertion pipe 17 is inserted into the communicating vessel insertion pipe 341.

[0162] The portion of the pipe section in the communicating vessel connector 341 that is not connected to the level box connector 17, together with the level box connector 17, defines the second communicating channel Q. The point with the smallest cross-sectional area of ​​the second communicating channel Q is located inside the level box connector 17.

[0163] In this embodiment of the application, the cross-sectional area S1 of the inner cavity B of the water purifier 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 the following:

[0164] S3 / S4=K*S1 / S2

[0165] Wherein, K is the resistance coefficient of the fluid in the liquid level box communication 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.

[0166] Furthermore, the value of the fluid resistance coefficient K will vary depending on the length or shape of the hole depth at the liquid level box connection port 11.

[0167] In this way, when the water purifier 100 is in use, the liquid levels in the water tank 20 and the liquid level box 10 are always completely consistent, so that the water level detected by the water level detector in the liquid level box 10 can reflect the real water level in the water tank 20 in real time, thus avoiding the occurrence of reverse water replication.

[0168] Furthermore, the cross-sectional area S1 of the inner cavity B of the water purifier 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.

[0169] The bottom wall of the inner cavity B of the water purification tank is flush with the bottom wall of the inner cavity A of the liquid level box.

[0170] In this way, the water level detected by the water level detector in the liquid level box 10 can be the actual water level in the clean water tank 20.

[0171] Furthermore, the cross-sectional area of ​​the first connecting port 32 is greater than the cross-sectional area of ​​the second connecting port 31.

[0172] Furthermore, the cross-sectional area of ​​the liquid level box connection port 11 is greater than or equal to 4.5 mm². 2 ; and / or the cross-sectional area of ​​the water tank connection port 21 is greater than 40 mm². 2 .

[0173] If the cross-sectional area of ​​the liquid level box connection port 11 is too large, i.e., the diameter of the liquid level box connection port 11 is too large, the water flow rate in the liquid level box 10 will be too fast, causing the water level in the liquid level box 10 to drop too quickly. This results in the liquid level in the liquid level box 10 falling below the water purification tank 20, causing the water level detected by the water level detector to fail to reflect the true water level in the water purification tank 20. Conversely, if the cross-sectional area of ​​the liquid level box connection port 11 is too small, i.e., the diameter of the liquid level box connection port 11 is too small, the water flow rate in the liquid level box 10 will be too slow, causing the water level in the liquid level box 10 to drop too slowly. Similarly, the water level detected by the water level detector will fail to reflect the true water level in the water purification tank 20.

[0174] When the cross-sectional area of ​​the liquid level box connection port 11 is greater than or equal to 4.5 mm 2 And / or the cross-sectional area of ​​the water tank connection port 21 is greater than 40mm². 2 At the same time, it can ensure that the water in the liquid level box 10 enters and exits the connector 30 through the liquid level box connection port 11, and the water in the clean water tank 20 enters and exits the connector 30 through the clean water tank connection 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 synchronized, so that the water level detection result of the liquid level box 10 detected by the water level detector can accurately reflect the water level in the clean water tank 20.

[0175] Figure 9 This is a schematic diagram showing the result of the first communication port 32 and the water tank communication port 21 cooperating in the water purifier 100 provided in the embodiment of this application.

[0176] In this embodiment of the application, as described above, a support member 81 is also provided on the outer wall of the housing 80, and the water tank 20 is detachably mounted on the support member 81.

[0177] Combination Figure 3 , Figure 8 and Figure 9 In order to connect the water tank 20 with the communicating vessel 30, the first communicating port 32 and the water tank communicating port 21 are respectively provided with a communicating vessel check valve 36 and a water tank check valve 27.

[0178] Furthermore, as mentioned above, the communicating vessel 30 is provided with a communicating vessel connecting pipe 34 that communicates with the inner cavity C of the communicating vessel. The communicating vessel connecting pipe 34 is located at a position corresponding to the first communicating port 32. In a specific implementation, at least part of the communicating vessel 30 is located inside the housing 80, and the communicating vessel connecting pipe 34 extends from inside the housing 80 to outside the housing 80 and extends to the bearing side of the bearing member 81.

[0179] With most of the communicating vessel 30 housed inside the housing 80, only the communicating vessel connecting pipe 34 for connecting to the water purifier 100 extends outside the housing 80, allowing the water tank 20 to be placed on the support member 81 outside the housing 80 for easy access by the user.

[0180] Correspondingly, the purified water tank 20 is provided with a purified water tank connecting pipe 22, which communicates with the inner cavity B of the purified water tank 20. The purified water tank connecting pipe 22 is located at a position corresponding to the purified water tank communication port 21. The communicating vessel check valve 36 is located inside the communicating vessel connecting pipe 34, and the purified water tank check valve 27 is located inside the purified water tank connecting pipe 22.

[0181] The water tank connecting pipe 22 is configured to be inserted into the communicating vessel connecting pipe 34 when supported on the carrier 81 so that the inner cavity C of the communicating vessel and the inner cavity B of the water tank are connected. For example, when the water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the water tank check valve 27 opens the valve core 361 of the communicating vessel check valve to realize the inlet and outlet of water between the communicating vessel 30 and the water tank 20.

[0182] More specifically, in combination Figure 3 , Figure 8 The communicating vessel connecting pipe 34 is equipped with a valve seat 362. The valve core 361 of the communicating vessel check valve is elastically connected to the valve seat 362, for example, through an elastic element. When the water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the valve core 271 of the water tank check valve overcomes the elastic force of the elastic element 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 water tank check valve to open the water tank check valve 27. When the water tank connecting pipe 22 is disconnected 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 element (not shown), closing the communicating vessel connecting pipe 34. Of course, when the water tank connecting pipe 22 is disconnected from the communicating vessel connecting pipe 34, the valve core 271 of the water tank check valve also returns to its original state under the action of the elastic element, closing the water tank connecting pipe 22.

[0183] For example, 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.

[0184] Thus, when the water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the valve core 271 of the water tank check valve can reliably press against the valve core 361 of the communicating vessel check valve, so as to smoothly open the communicating vessel check valve 36 and realize the inlet and outlet of water from the communicating vessel 30 to the water tank 20.

[0185] Figure 10 A cross-sectional view of the water purifier 100 provided in this embodiment of the application, showing that the first communication port 32 and the water tank communication port 21 are separated. Figure 11 for Figure 10 A magnified view of the area at point U; Figure 12 This is a cross-sectional view of the first communication port 32 and the water tank communication port 21 in the water purifier 100 provided in the embodiment of this application. Figure 13 for Figure 12 A magnified view of a portion of point V. Figure 14 This is a schematic diagram illustrating the structure of the sealing ring 35 and the communicating vessel connecting pipe 34 in the water purifier 100 provided in this embodiment of the application. It should be noted that... Figure 12 and Figure 13 In order to facilitate observation, the structure of the check valve 27 of the clean water tank is omitted.

[0186] In the embodiments of this application, reference is made to Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 The inner wall of the connecting pipe 34 is provided with a sealing ring 35. The two axial ends of the sealing ring 35 abut against the inner wall of the connecting pipe 34. The first sealing section 353 between the two axial ends of the sealing ring 35 and the inner wall of the connecting pipe 34 together define the water storage chamber F. The water tank connecting pipe 22 is configured to be able to be inserted into the connecting pipe 34 when supported on the support member 81 so that the inner cavity C of the connecting pipe and the inner cavity B of the water tank are connected. The first sealing section 353 is elastically deformed radially outward to squeeze the water in the water storage chamber F into the connecting pipe 34. When it is removed from the connecting pipe 34, the first sealing section 353 is elastically reset radially inward to absorb the water in the connecting pipe 34 into the water storage chamber F.

[0187] In the above solution, the water storage chamber F is defined by the first sealing section 353 between the two axial ends of the sealing ring 35 and the inner wall of the connecting pipe 34. The water storage chamber F has a certain water storage capacity. Since the water tank connecting pipe 22 can elastically reset the first sealing section 353 radially inward when it is disconnected from the connecting pipe 34, the water in the connecting pipe 34 is absorbed into the water storage chamber F. Therefore, when the water tank 20 is taken away by the user and the water tank connecting pipe 22 is disconnected from the connecting pipe 34, even if water flows into the connecting pipe 34 from the connecting vessel 30, it will be partially or completely absorbed by the water storage chamber F. This alleviates the problem of some water flowing into the connecting pipe 34 due to the instantaneous disconnection of the water tank connecting pipe 22 and the connecting pipe 34 when the water tank 20 is taken away.

[0188] Continue to refer to Figure 11 and Figure 13 Furthermore, the end of the sealing ring 35 facing the water tank 20 is defined as the first end 351, and the end away from the water tank 20 is defined as the second end 352.

[0189] The first end 351 is provided with an annular flange 3511. The flange 3511 and the outer peripheral surface of the sealing ring 35 define a flange mounting groove G. The end of the communicating vessel connecting pipe 34 facing the water tank 20 is snapped into the flange mounting groove G so that the structure of the first end 351 abuts against the inner wall of the communicating vessel connecting pipe 34.

[0190] Thus, the first end 351 of the sealing ring 35 covers the end of the communicating vessel connecting pipe 34 facing the water tank 20, which can prevent water in the water storage chamber F from leaking from the first end 351, that is, the side facing the water tank 20.

[0191] Furthermore, the second end 352 is provided with an annular protrusion 3521, which abuts against the inner wall of the communicating vessel connecting pipe 34. The protrusion 3521, the outer peripheral surface of the first sealing section 353, and the flange 3511 together define a water storage groove, which together with the inner wall of the communicating vessel connecting pipe 34 defines a water storage cavity F.

[0192] Thus, by setting a water-storing groove on the sealing ring 35 to form the water-storing cavity F, the structure is relatively simple and easy to manufacture. Furthermore, it facilitates the insertion of the water tank connecting pipe 22 into the inner side of the sealing ring 35, pressing the inner circumferential surface of the sealing ring 35 radially outward, causing the first sealing section 353 to elastically deform radially outward, thereby squeezing the water in the water-storing cavity F into the communicating vessel connecting pipe 34.

[0193] In this embodiment, reference continues to be made to... Figure 11 The inner circumferential surface of the first sealing section 353 is provided with at least two annular interference fit parts 3531. The at least two interference fit parts 3531 are spaced apart along the axial direction of the sealing ring 35, and the at least two interference fit parts 3531 are used to interfere with the water tank connecting pipe 22.

[0194] In this way, when the water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, it can be sealed with the sealing ring 35 to prevent water from leaking between the water tank connecting pipe 22 and the communicating vessel connecting pipe 34.

[0195] For example, along the direction from the first end 351 toward 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.

[0196] Insert the water tank connecting pipe 22 into the communicating vessel connecting pipe 34 along the direction from the first end 351 to the second end 352, i.e., the direction from which the water tank connecting pipe 22 is inserted. During the insertion process, the water tank connecting pipe 22 first contacts the interference fit part 3531 with a higher protrusion, which can quickly seal the water and prevent leakage. Continuing to insert, the water tank connecting pipe 22 engages with the interference fit part 3531 with a lower protrusion. The interference amount is relatively small, which can reduce the difficulty of inserting the water tank connecting pipe 22 and improve the insertion feel.

[0197] In the embodiments of this application, reference is made to Figure 14 There are two interference fit parts 3531. On the outer peripheral surface of the sealing ring 35, there is a support protrusion 354 between the areas corresponding to the two interference fit parts 3531.

[0198] Thus, when the water tank connecting pipe 22 is inserted into the inner side of the sealing ring 35, the interference fit part 3531 elastically deforms towards the inner wall of the communicating vessel connecting pipe 34 under the pressure of the water tank connecting pipe 22. The support protrusion 354 first contacts the inner wall of the communicating vessel connecting pipe 34. At this time, on the outer circumference of the sealing ring 35, the area corresponding to the two interference fit parts 3531 will form two clearance spaces with the inner wall of the communicating vessel connecting pipe 34. The existence of the two clearance spaces allows the two interference fit parts 3531 to still have room for elastic deformation in the radially outward or radially inward direction, preventing the water tank connecting pipe 22 from being mismatched with the sealing ring 35 due to dimensional tolerances, and also solving the problem of poor feel during the insertion process of the water tank connecting pipe 22.

[0199] Furthermore, there are two interference fit parts 3531. On the outer peripheral surface of the sealing ring 35, there are relief grooves H in the areas corresponding to the two interference fit parts 3531 respectively. The groove depth of the relief groove H corresponding to the interference fit part 3531 with higher protrusion height is greater than the groove depth of the relief groove H corresponding to the interference fit part 3531 with lower protrusion height.

[0200] This design allows the high-protrusion interference fit part 3531 to have a larger clearance space, while the low-protrusion interference fit part 3531 has a smaller clearance space. This differentiated design maximizes the capacity of the water storage cavity F.

[0201] Combination Figure 3 , Figure 9 and Figure 13 When the water tank connecting pipe 22 of the water tank 20 is inserted into the communicating vessel connecting pipe 34, the valve core 271 of the 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 inner cavity B of the water tank 20 and the inner cavity C of the communicating vessel 30 are connected. At this time, the water tank connecting pipe 22 is inserted into the inner side of the sealing ring 35 and pushes the first sealing section 353 radially outward toward the sealing ring 35, so that the outer wall of the first sealing section 353 presses against the inner wall of the communicating vessel connecting pipe 34, and the water storage cavity F is flattened. When the water tank connecting pipe 22 is pulled 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 compression of the first sealing section 353 by the communicating vessel connecting pipe 34 disappears, the sealing ring 35 is restored, and the water storage chamber F returns to its original state. The water that flows out into the communicating vessel connecting pipe 34 will be squeezed into the water storage chamber F due to atmospheric pressure and temporarily stored in the water storage chamber F.

[0202] Figure 15 This is a schematic diagram of the connection between the support member 81 and the housing 80 in the water purifier 100 provided in the embodiments of this application.

[0203] In the embodiments of this application, reference is made to Figure 15 As mentioned above, the support member 81 is detachably connected to the housing 80, for example, to the front panel 873. The support member 81 is constructed with a water collection cavity D, and the top wall of the support member 81 is provided with a water collection hole 82 communicating with the water collection cavity D. The water tank 20 is supported on the top wall of the support member 81.

[0204] Thus, water leaking from the connection between the water tank 20 and the communicating vessel 30 can enter the water collection chamber D through the water collection hole 82. Alternatively, the user can place a water cup on the support 81, and water outside the water cup and outside the water tank 20 can also be poured into the water collection chamber D through the water collection hole 82.

[0205] Furthermore, the outer wall of the housing 80 is provided with a water guiding part 83, and the carrier 81 is detachably connected to the housing 80 by inserting and engaging with the water guiding part 83.

[0206] The water guiding part 83 has a guiding surface 831, and a guiding hole 832 communicating with the water collecting cavity D is provided on the guiding surface 831. The guiding surface 831 is configured to guide the water in the communicating vessel connecting pipe 34 to the guiding hole 832.

[0207] Thus, as Figure 15 As shown by the dotted line, water in the communicating vessel connecting pipe 34 can be guided to the guide hole 832 through the guide part, and finally flow into the water collection chamber D. The user can periodically remove the support member 81 and clean the water in the water collection chamber D.

[0208] Furthermore, to better guide the water flowing out of the communicating vessel connecting pipe 34, the projection of the end of the communicating vessel connecting pipe 34 facing the water purification tank 20 onto the first plane is located within the range of the projection of the guide surface 831 onto the first plane, wherein the first plane is perpendicular to the height direction of the water purifier 100. Thus, when water leaks from the end of the communicating vessel connecting pipe 34 and falls under gravity, it can be completely caught by the guide surface 831 and collected into the water collection chamber D.

[0209] In practice, the guide surface 831 is constructed as a conical surface centered on the guide hole 832. This inclined conical surface provides better water guidance.

[0210] Furthermore, the housing 80 is provided with a through hole 8733 for the connecting pipe 34 of the communicating vessel to pass through; the communicating vessel 30 also includes a pressure cap 37, which is connected to the edge of the opening of the through hole 8733, and the pressure cap 37 has a pressure cap opening 371 for the water tank connecting pipe 22 to be inserted into the connecting pipe 34 of the communicating vessel, and the pressure cap 37 presses the end of the sealing ring 35 facing the water tank 20 onto the connecting pipe 34 of the communicating vessel.

[0211] In this way, the sealing ring 35 can be reliably fixed to the connecting pipe 34 of the communicating vessel. For example, the end of the gland 37 is provided with an inwardly bent portion, and the top end of the bent portion is pressed against the sealing ring 35.

[0212] In contrast, referring to Figure 10 The outer wall of the water purification tank 20 has a water purification tank mounting groove 28. The water purification tank connecting pipe 22 is set on the bottom wall of the water purification tank mounting groove 28. A receiving space I is defined between the outer wall of the water purification tank connecting pipe 22 and the side wall of the water purification tank mounting groove 28. The receiving space I is used to receive the pressure cap 37. In this way, the surface of the water purification tank 20 is relatively flat and the structure is more aesthetically pleasing.

[0213] In this embodiment of the application, combined with Figure 2 and Figure 15 In order to detect whether the water tank 20 is located on the support member 81, the water purifier 100 also includes a sensor assembly 86, which is disposed inside the housing 80 and configured to detect the relative position of the water tank 20 and the support member 81.

[0214] The sensor assembly 86 can be positioned, for example, inside the housing 80, so that its detection end extends from inside the housing 80 to outside, and then to the bearing side of the support member 81. To trigger the sensor assembly 86, a triggering part 861 is provided on the outer wall of the water tank 20 at a position corresponding to the detection end. The triggering part 861 is configured to contact the detection end when the water tank 20 is supported on the support member 81, triggering the sensor assembly 86 to perform detection. This facilitates determination of whether the water tank 20 is located on the support member 81.

[0215] In a specific implementation, the sensor assembly 86 can be, for example, a micro switch. When the water tank 20 is placed on the support 81, the triggering part 861 triggers the detection end of the sensor assembly 86 to detect that the water tank 20 is in place.

[0216] Figure 16 This is a cross-sectional view of the purified water tank 20 in the water purifier 100 provided in the embodiments of this application. Figure 17 This is a cross-sectional view of the water purification tank 20 in the water purifier 100 provided in this embodiment of the application from another angle. Figure 18 for Figure 17 A magnified view of the area at point X. Figure 19 This is an exploded view of the sterilization unit 90 in the water purifier 100 provided in this embodiment of the application.

[0217] Reference Figure 16 , Figure 17 , Figure 18 , Figure 19In this embodiment of the application, the water purifier 100 further includes a sterilization unit 90 to sterilize and disinfect the purified water stored in the water tank 20.

[0218] Specifically, in combination Figure 10 and Figure 17 The water tank 20 is also provided with a first mounting groove 29, and the bottom wall of the first mounting groove 29 is provided with a first mounting port 291.

[0219] Combination Figure 18 and Figure 19 The sterilization unit 90 includes a lampshade 91, a lampshade positioning assembly 92, and a sterilizing 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 a first mounting groove 29, and the head of the lampshade 91 is exposed to the clean water tank 20 through a first mounting opening 291. The first positioning member 93 is fitted onto the outer periphery of the lampshade 91. The first sealing ring 94 is sealed between the first positioning member 93 and the side wall of the first mounting groove 29, and the second sealing ring 95 is sealed between the first positioning member 93 and the outer periphery of the lampshade 91. In a specific implementation, for example, the first sealing ring 94 is interference-fitted between the first positioning member 93 and the side wall of the first mounting groove 29, and the second sealing ring 95 is interference-fitted between the first positioning member 93 and the outer periphery of the lampshade 91.

[0220] The germicidal lamp 96 is located on the outer wall of the housing 80. When the water tank 20 is supported on the support member 81, the germicidal lamp 96 can extend into the inside of the lamp cover 91.

[0221] In the above scheme, the water purification tank 20 is detachably mounted on the support member 81 on the outer wall of the housing 80, allowing the user to remove the water purification tank 20 at any time as needed. A first positioning member 93 is fitted onto the outer periphery of the lampshade 91, a first sealing ring 94 is sealed between the first positioning member 93 and the side wall of the first mounting groove 29, and a second sealing ring 95 is sealed between the first positioning member 93 and the outer periphery of the lampshade 91. This allows the lampshade 91 to be installed in the first mounting groove 29. Since the head of the lampshade 91 is exposed inside the water purification tank 20 through the first mounting opening 291, and the sterilizing lamp 96 extends into the inner side of the lampshade 91 when the water purification tank 20 is supported on the support member 81, the light emitted by the sterilizing lamp 96 located inside the lampshade 91 passes through the lampshade 91 and illuminates the water inside the water purification tank 20 to sterilize the water.

[0222] Furthermore, the lampshade positioning assembly 92 includes a first positioning member 93, a first sealing ring 94 and a second sealing ring 95 respectively disposed on the outer and inner sides of the first positioning member 93. The first positioning member 93 serves as a supporting frame, while the first sealing ring 94 and the second sealing ring 95 primarily function as deformation seals. Compared to related technologies that simply use a sealing ring 35, where the radial thickness of the entire sealing ring 35 is relatively large, the radial thickness of the first sealing ring 94 and the second sealing ring 95, which undergo deformation, is smaller. This slows down the degree and speed of aging, thus improving the reliability of the seal. With prolonged use, the possibility of leakage is reduced.

[0223] For example, the lampshade 91 is a light-transmitting structure. For instance, the head of the lampshade 91 can extend into the clean water tank 20 through the first mounting port 291 to maximize the coverage of the water by the germicidal lamp 96. The germicidal lamp 96 can be, for example, an ultraviolet germicidal lamp.

[0224] In practice, the hardness of the first positioning member 93 is greater than that of the first sealing ring 94 and the second sealing ring 95. This can further reduce the aging rate of the lampshade 91 mounting assembly and improve the overall strength of the lampshade 91 mounting assembly. For example, the first positioning member 93 can be made of metal, and the first sealing ring 94 and the second sealing ring 95 can be made of rubber.

[0225] Of course, to increase sealing performance, at least two first sealing rings 94 are arranged along the axial direction of the first positioning member 93. Similarly, 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 along the axial direction of the first positioning member 93 to minimize the occurrence of water leakage.

[0226] Continue to refer to Figure 19 When there are multiple first sealing rings 94 and second sealing rings 95, in order to achieve axial positioning, at least one annular second mounting groove 932 can be provided on the outer peripheral surface of the first positioning member 93, and the first sealing rings 94 can be installed in the second mounting grooves 932 in a corresponding manner. In this way, it is possible to prevent the first sealing rings 94 from moving axially in the first positioning member 93.

[0227] The inner circumferential surface of the first positioning member 93 is provided with at least one annular stop portion 931. The stop portion 931 and the inner circumferential side of the first positioning member 93 define a semi-open annular mounting space J, and the second sealing ring 95 is installed in the annular mounting space J. In this way, the stop portion 931 and the sealing member 97 together form a mounting space for installing the second sealing ring 95.

[0228] In this embodiment of the application, combined with Figure 18 and Figure 19The lampshade positioning assembly 92 also includes a sealing member 97, which is connected to the end of the first positioning member 93 facing the water tank 20 and blocks the side of the second sealing ring 95 facing the water tank 20. This prevents the second sealing ring 95 from disengaging from the gap between the first positioning member 93 and the lampshade 91.

[0229] For example, the sealing member 97 and the first positioning member 93 can be connected by a snap-fit ​​arm 973 on the sealing member 97 and a snap-fit ​​groove 974 on the first positioning member 93. The sealing member 97 and the first positioning member 93 are connected by the snap-fit ​​engagement of the snap-fit ​​arm 973 and the snap-fit ​​groove 974. This allows the first positioning member 93 and the sealing member 97 to be reliably connected as one unit.

[0230] Furthermore, the sealing member 97 has an annular first abutment portion 971 and abutment portion 972 at its axial end along the first positioning member 93. The first abutment portion 971 is configured to abut against the second sealing ring 95, and the second abutment portion 972 is configured to abut against the end of the lampshade 91 facing the water tank 20. This prevents the second sealing ring 95 from shifting axially in the first positioning member 93 and prevents the lampshade 91 from dislodging from the first mounting groove 29.

[0231] Continue to refer to Figure 18 The germicidal lamp 96 includes a germicidal lamp mounting bracket 961 and a lamp body 962. The germicidal lamp mounting bracket 961 is installed on the outer wall of the housing 80 at a position corresponding to the first mounting opening 291, and the lamp body 962 is installed at the end of the germicidal lamp mounting bracket 961 facing the water tank 20. This allows the germicidal lamp 96 to be installed at a position corresponding to the lamp cover 91.

[0232] Of course, the housing 80 is provided with a second mounting port 8732 so that the germicidal lamp mounting bracket 961 can pass through the second mounting port 8732 and extend out of the housing 80.

[0233] Continue to refer to Figure 17 The first mounting port 291 and the water tank connection port 21 are both located between the top and bottom of the water tank 20, with the first mounting port 291 positioned higher than the water tank connection port 21. This ensures that the sterilizing light emitted by the sterilizing lamp 96 covers the water in the water tank 20 as much as possible.

[0234] Figure 20 This is a cross-sectional view of a water purification tank 20 with another structure in the water purifier 100 provided in this application embodiment. Figure 21 This is a cross-sectional view from another angle of the water purification tank 20 in the water purifier 100 provided in this application embodiment. Figure 22 for Figure 21 A magnified view of the area at point Y.

[0235] Reference Figure 20, Figure 21 , Figure 22 In the aforementioned solution, a hole needs to be drilled on the front panel 873 to install the germicidal lamp 96, which affects the user's viewing experience. Therefore, it is possible to consider setting the germicidal unit 90 to wireless mode.

[0236] In a specific implementation, the sterilization unit 90 may include a lamp holder 98, which passes through the first mounting opening 291 and is sealed to it. For example, the lamp holder 98 may have a flange 982 at its first end, which overlaps the edge of the first mounting opening 291. A third sealing ring 981 may be provided on both the flange 982 and the edge of the first mounting opening 291. In this case, the sterilization lamp 96 can be installed at the end of the lamp holder 98 facing the inside of the water purification tank 20. Thus, the sterilization lamp 96 extends directly into the interior of the water purification tank 20, resulting in a larger irradiation range within the water purification tank 20 compared to the previous solution.

[0237] Furthermore, continue to refer to Figure 22 The sterilization unit 90 also includes a second mounting member 983 sleeved on the lamp holder 98. The second mounting member 983 can be located outside the water tank 20, for example, inside the first mounting groove 29, and is used to apply a force toward the outside of the water tank 20 to the flange portion 982, so that the flange portion 982 abuts the third sealing ring 981 against the inner wall of the water tank 20. In practical applications, the second mounting member 983 can abut against the bottom wall of the first mounting groove 29, and the second mounting member 983 and the lamp holder 98 can be threaded together. In this case, the flange portion 982, the first sealing ring 94, and the second mounting member 983 abut against the bottom of the first mounting groove 29 from the inner and outer sides of the water tank 20, respectively.

[0238] To position the germicidal lamp 96, the end of the lamp holder 98 facing the inside of the water tank 20 is provided with a mounting groove, in which the germicidal lamp 96 is sealed and installed.

[0239] In this embodiment, the sterilization unit 90 further includes a wireless component 99, which includes a wireless transmitting unit 991 and a wireless receiving unit 992. The wireless transmitting unit 991 is installed on the inner wall of the housing 80 and electrically connected to the power supply circuit board (not shown) of the water purifier 100. The wireless receiving unit 992 is installed on the end of the lamp holder 98 facing the outside of the water tank 20. When the water tank 20 is supported on the carrier 81, the wireless transmitting unit 991 and the wireless receiving unit 992 are arranged opposite each other to supply power to the sterilization lamp 96 via the wireless receiving unit 992.

[0240] Figure 23 This is a schematic diagram of the structure of the water vapor separator provided in the embodiments of this application; Figure 24a This is a cross-sectional structural schematic diagram of a water vapor separator provided in an embodiment of this application; Figure 24bThis is a structural schematic diagram of the water purifier provided in an embodiment of this application from another angle; Figure 25 for Figure 24a A magnified view of the area at point Z; Figure 26 This is a schematic diagram of the water vapor separator provided in an embodiment of this application from another angle; Figure 27 A partial cross-sectional view of a water vapor separator provided in an embodiment of this application; Figure 28 This is a cross-sectional view from another angle of the water vapor separator provided in an embodiment of this application. It will be understood that this view is for ease of observation of the internal structure. Figure 26 The diagram shows the first-stage separator cover 641 in the open state relative to the first-stage separator body 64.

[0241] In this embodiment of the application, as described above, the water vapor separator 60 is used to separate the steam in the heated purified water. The water vapor separator 60 is provided with a water vapor separation outlet 61, which forms the water intake of the water purifier 100.

[0242] In the water vapor separators of the relevant technology, there is a problem with poor steam separation effect. The water flowing out of the water vapor separator outlet contains a lot of steam. In order to avoid this problem, the water purifiers of the relevant technology often control the outlet water temperature at about 93℃ to reduce the steam content in the outlet water. Therefore, the water purifiers of the relevant technology have the problem of insufficient outlet water temperature.

[0243] To address this issue, the present application also improves the structure of the water vapor separator 60.

[0244] Specifically, in combination Figure 23 , Figure 24a , Figure 25 The water vapor separator 60 includes a primary water vapor separator 63 and a secondary water vapor separator 65 for water vapor separation. The primary water vapor separator 63 and the secondary water vapor separator 65 are respectively constructed with a primary water vapor separation chamber K and a secondary water vapor separation chamber L that are interconnected.

[0245] The primary water vapor separator 63 is provided with a water vapor separation inlet 631 and a first air outlet 632 connected to the primary water vapor separation chamber K. The water vapor separation outlet 61 and the water vapor separation air outlet 62 are provided on the secondary water vapor separator 65 and connected to the secondary water vapor separation chamber L. The water vapor separation inlet 631 is used to connect with the hot water supply source.

[0246] The water vapor separation inlet 631 is located on the bottom wall 633 of the first-stage water vapor separation chamber. The bottom wall 633 of the first-stage water vapor separation chamber is provided with a first guide pipe 635 extending toward the top wall 634 of the first-stage water vapor separation chamber. The first guide pipe 635 is connected to the water vapor separation inlet 631. The top wall 634 of the first-stage water vapor separation chamber is also provided with a guide wall 66 extending toward the bottom wall 633 of the first-stage water vapor separation chamber. The guide wall 66 is blocked on the circumferential outer side of at least a portion of the first guide pipe 635.

[0247] The water vapor separator 60 includes a primary water vapor separator 63 and a secondary water vapor separator 65 for water vapor separation. The primary water vapor separation chamber K in the primary water vapor separator 63 and the secondary water vapor separation chamber L in the secondary water vapor separator 65 are interconnected. In this way, the water vapor mixture first enters the primary water vapor separator 63 for a first water vapor separation, and then enters the secondary water vapor separator 65 for a second water vapor separation, resulting in a better water vapor separation effect.

[0248] On the other hand, a water vapor separation inlet 631 is provided on the bottom wall 633 of the first-stage water vapor separation chamber, and the bottom wall 633 of the first-stage water vapor separation chamber is provided with a first guide pipe 635 extending toward the top wall 634 of the first-stage water vapor separation chamber. In this way, the water vapor mixture entering the first-stage water vapor separation chamber K from the water vapor separation inlet 631 enters the first guide pipe 635. In addition, the top wall 634 of the primary water vapor separation chamber is provided with a guide wall 66 extending towards the bottom wall 633 of the primary water vapor separation chamber. The guide wall 66 is positioned on the circumferential outer side of at least a portion of the first guide pipe 635. Thus, after the water vapor mixture in the first guide pipe 635 detaches from the first guide pipe 635, it rushes towards the top wall 634 of the primary water vapor separation chamber. The top wall 634 of the primary water vapor separation chamber can disperse the water vapor mixture, separating some of the steam from the water flow. The water flows downward along the guide wall 66 into the bottom of the primary water vapor separation chamber K, while the steam rises and exits from the first air outlet 632 into the primary water vapor separator 63. As described above, when the water vapor separation effect is good, the amount of steam in the water is small, and the outlet water temperature of the water purifier can be set higher to meet the user's water needs.

[0249] The hot water source can be, for example, a heater 55, whose outlet 551 can be connected to the water-vapor separator inlet 631 via a fifth pipe 105. Of course, in other embodiments, the outlet 551 can also be directly connected to the water-vapor separator inlet 631.

[0250] In this embodiment, the bottom end of the guide wall 66 facing the bottom wall 633 of the primary water vapor separation chamber is at a lower height than the top end of the first guide pipe 635 facing the primary water vapor separation chamber K.

[0251] By positioning the bottom end of the guide wall 66 lower than the top end of the first guide pipe 635, it can be ensured that after the water vapor mixture flushed out from the first guide pipe 635 is dispersed by the top wall 634 of the first-stage water vapor separation chamber, the dispersed water flow can reliably fall along the guide wall 66 onto the bottom wall 633 of the first-stage water vapor separation chamber, and will not enter the first guide pipe 635 from the top end of the first guide pipe 635.

[0252] Furthermore, referring to Figure 27 A dispersing chamber M is defined by the guide wall 66 and the side wall 636 of part of the first-stage water vapor separation chamber, and the top part of the first guide pipe 635 extends into the dispersing chamber M.

[0253] In some embodiments, at least part of the outer wall of the first guide tube 635 is integrally formed with the inner wall of the primary water vapor separation chamber K to facilitate the manufacturing process.

[0254] Combination Figure 24a and Figure 27 Furthermore, the outer wall of the primary water vapor separator 63 is provided with a first mounting pipe 637 that is coaxial with and communicates with the first guide pipe 635. This facilitates the introduction of the water vapor mixture flowing out of the heater outlet 551 into the first guide pipe 635.

[0255] Furthermore, the first air outlet 632 is disposed on the side wall 636 of the primary water vapor separation chamber. The side wall 636 of the primary water vapor separation chamber is provided with a second guide pipe 638 extending toward the top wall 634 of the primary water vapor separation chamber. The second guide pipe 638 is connected to the first air outlet 632. A guide wall 66 extends between the first guide pipe 635 and the second guide pipe 638, and the top ends of the first guide pipe 635 and the second guide pipe 638 are separated by the guide wall 66.

[0256] With this configuration, the bottom end of the guide wall 66 is actually lower than the top end of the second guide pipe 638. After the water vapor mixture flushed out by the first guide pipe 635 is dispersed by the top wall 634 of the first-stage water vapor separation chamber, the water flows downward from the side of the guide wall 66 toward the first guide pipe 635. Due to the obstruction of the guide wall 66, it will not enter the second guide pipe 638.

[0257] Similar to the first guide tube 635, at least part of the outer wall of the second guide tube 638 is integrally constructed with the inner wall of the primary water vapor separation chamber K, which facilitates the processing and manufacturing process.

[0258] In this embodiment, the outer wall of the primary water vapor separator 63 is provided with a second mounting pipe 639, which is coaxial with and communicates with the second guide pipe 638. This facilitates the extraction of steam after water vapor separation from the primary water vapor separation chamber K. For specific implementation, for example, refer to... Figure 24a The second installation pipe 639 can be connected to the water vapor separation outlet 62 on the secondary water vapor separator 65 through the sixth pipe 106.

[0259] Continue to refer to Figure 26 and Figure 27 Furthermore, the primary water vapor separator 63 includes a primary separator body 64 and a primary separator cover 641 covering the primary separator body 64, with a flow guide wall 66 disposed on the primary separator cover 641. This arrangement facilitates the processing.

[0260] Combination Figure 24a , Figure 27 , Figure 28 The primary water vapor separator 63 is provided with a first connection port 642 that communicates with the primary water vapor separation chamber K, and the secondary water vapor separator 65 is provided with a second connection port 651 that communicates with the secondary water vapor separation chamber L. The first connection port 642 and the second connection port 651 are connected.

[0261] The top wall 652 of the secondary water vapor separation chamber is also provided with a third guide pipe 655 extending toward the bottom wall 653 of the secondary water vapor separation chamber, and the third guide pipe 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 positioned between the outer circumferential side of the third guide pipe 655 and the water vapor separation outlet 61.

[0262] A third guide pipe 655 extending from the top wall 652 of the secondary water vapor separation chamber toward the bottom wall 653 of the secondary water vapor separation chamber is also provided. 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, separating the steam mixed in the water flow from the water flow. The bottom wall 653 of the secondary water vapor separation chamber is provided with a stop wall 654 extending toward the top wall of the secondary water vapor separation chamber. The stop wall 654 is arranged around the third guide pipe 655. The water flow, after being dispersed and separated on the bottom wall 653 of the secondary water-vapor separation chamber, flows towards the water-vapor separation outlet 61. Upon encountering the baffle wall 654, it is dispersed again, undergoing further water-vapor separation. The separated steam flows out of the secondary water-vapor separation chamber L through the water-vapor separation outlet 62. The water flow, dispersed again by the baffle wall 654, contains less steam and can then flow out of the secondary water-vapor separation chamber L through the water-vapor separation outlet 61. Thus, the water flow entering the secondary water-vapor separation chamber L undergoes two water-vapor separations before being combined with the primary water-vapor separator 63, achieving a better water-vapor separation effect for hot water.

[0263] Combination Figure 24a , Figure 28Furthermore, the bottom wall 653 of the secondary water vapor separation chamber is constructed with a retention tank N spaced apart from the water vapor separation outlet, and the bottom end of the third guide pipe 655 extends into the retention tank N.

[0264] By extending the bottom end of the third guide pipe 655 into the retention tank N, i.e., the height of the bottom end of the third guide pipe 655 is lower than the height of the edge of the retention tank N, when water intake stops, the water flowing out of the primary water vapor separation chamber K will be pushed out of the third guide pipe 655 due to water inertia and the viscosity of water, causing the water level in the third guide pipe 655 to be lower than the water level in the retention tank N (when it is full of water). As time goes on, the water in the third guide pipe 655 gradually stabilizes, and some of the water in the retention tank N returns to the third guide pipe 655, making the water level in the third guide pipe 655 equal to the water level in the retention tank N, thus lowering the water level in the retention tank N. If the water level is below the edge of the tank and not full, and if residual water droplets in the primary water vapor separation chamber K drip into the secondary water vapor separator 65, the water level in the retention tank N and the third guide pipe 655 will rise accordingly. However, due to the viscosity of water, it will stick to the side wall of the retention tank N, meaning that the water in the retention tank N will not flow out. Therefore, no water droplets will fall from the water vapor separator outlet 61. In this way, the effect of quickly sealing the water when water intake is stopped is achieved, effectively improving the problem of water leakage at the water intake of the water purifier 100.

[0265] In related technologies, air can easily enter the inner cavity of the water vapor separator 60 through the water vapor separator outlet 61. Over time, this can easily lead to bacterial growth, and since the inner cavity is an area that users cannot clean, this is addressed by the inclusion of a retention tank N. After water intake stops, the bottom end of the third guide pipe 655 extends into the retention tank N, acting as a liquid seal. This prevents external air from entering the inner cavity of the water vapor separator 60, especially the primary water vapor separator 63, inhibiting bacterial growth and making the water output from the water vapor separator 60 cleaner and more hygienic.

[0266] In some embodiments, the baffle wall 654 and the sidewall 656 of part of the secondary water vapor separation chamber define the aforementioned retention groove N. This configuration allows for a smaller volume of the secondary water vapor separator 65 compared to slotting the bottom wall 653 of the secondary water vapor separation chamber.

[0267] Combination Figure 23 and Figure 24a Furthermore, the outer wall of the primary water vapor separator 63 is provided with a first mating pipe 657 that communicates with the first connection port 642, and the secondary water vapor separator 65 is provided with a first mating slot 658 that communicates with the second connection port 651. The first mating pipe 657 and the first mating slot 658 are inserted and mated to connect the first connection port 642 and the second connection port 651.

[0268] It is understandable that, in order to prevent water leakage between the first mating pipe 657 and the first mating slot 658, a sealing element 660 can be provided between the outer wall of the first mating pipe 657 and the inner groove wall of the first mating slot 658. The sealing element 660 can be an annular sealing ring, which is sleeved on the outer periphery of the first mating pipe 657 and sandwiched between the first mating pipe 657 and the first mating slot 658.

[0269] This allows the primary water vapor separator 63 and the secondary water vapor separator 65 to be inserted and fitted together, resulting in a relatively secure connection. Of course, it is understandable that, referring to... Figure 23 The primary water vapor separator 63 and the secondary water vapor separator 65 can also be fixedly connected by fasteners 643, making the connection between the two more secure. Multiple locating ribs 659 arranged at intervals along the circumference can also be provided on the outer peripheral wall of the first mating pipe 657. The locating ribs 659 abut against the groove of the first mating slot 658 to assist in positioning the insertion and mating of the first mating pipe 657 and the first mating slot 658.

[0270] Combination Figure 23 and Figure 24a Furthermore, the secondary water vapor separator 65 includes a secondary water vapor separator body 671 and a secondary water vapor separator cover 673 covering the secondary water vapor separator body 671. A first mating slot 658 is provided on the top side of the secondary water vapor separator cover 673, and a third guide pipe 655 is provided on the bottom side of the secondary water vapor separator cover 673 and communicates with the first mating slot 658.

[0271] Thus, after the first mating pipe 657 is inserted into the first mating slot 658, the water flowing out of the first mating pipe 657 can directly enter the third guide pipe 655. In specific implementation, the first mating pipe 657 and the third guide pipe 655 can be arranged coaxially.

[0272] Furthermore, the water vapor separation outlet 61 is located 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 constructed as an inclined wall structure that slopes towards the water vapor separation outlet 61. In this way, water flowing out of the retention tank N can flow more easily along the inclined wall into the water vapor separation outlet 61.

[0273] Combination Figure 24a and Figure 27 Furthermore, the water vapor separation outlet 62 is located on the bottom wall 653 of the secondary water vapor separation chamber and between the water vapor separation outlet 61 and the baffle wall 654.

[0274] A fourth guide pipe 672 is provided on the bottom wall 653 of the secondary water vapor separation chamber, extending toward the top wall 652 of the secondary water vapor separation chamber. The fourth guide pipe 672 is connected to the water vapor separation outlet 62, and the top end of the fourth guide pipe 672 is spaced apart from the top wall 652 of the secondary water vapor separation chamber.

[0275] Thus, the steam separated in the secondary water vapor separation chamber L rises upward and gathers at the top of the secondary water vapor separation chamber L. It can then enter the fourth guide pipe 672 from the top end of the fourth guide pipe 672 and flow out of the secondary water vapor separation chamber L from the water vapor separation outlet 62.

[0276] Furthermore, the water vapor separation outlet 62 is located on the bottom wall 653 of the secondary water vapor separation chamber, near the water vapor separation outlet 61.

[0277] In this embodiment of the application, a relief recess O is provided on the inner wall of the secondary water vapor separation cover 673 at the position corresponding to the fourth guide pipe 672, and the top end of the fourth guide pipe 672 extends into the relief recess O.

[0278] In this way, even with a longer length of the fourth guide tube 672, the external profile dimensions of the secondary water vapor separator 65 will not increase.

[0279] Furthermore, the water vapor separation outlet 62 is located between the water vapor separation outlet 61 and the second connection port 651, and the positions of the first connection port 642 and the second connection port 651 correspond to each other.

[0280] Furthermore, the water vapor separation outlet 61, the water vapor separation gas outlet 62, and the first connection port 642 are arranged in a row.

[0281] Reference Figure 24b As mentioned above, the outer wall of the housing 80 is provided with a support member 81, on which a water collection box 85 is formed. When taking water, the user can place the water container on the water collection box 85 to take water from the water vapor separator outlet 61. The water vapor separator 60, especially the water vapor separator outlet 61 and the water vapor separator outlet 62, needs to be located above the support member 81 (water collection box 85) and also correspond to the position of the support member 81.

[0282] Of course, as mentioned above, clearance openings need to be provided on the housing 80 so that some structures of the water vapor separator 60 can be exposed to the outside of the housing 80. For example, the water vapor separator outlet 61 and the water vapor separator gas outlet 62 need to be located on the outside of the housing 80. This is to facilitate water intake and to prevent the discharged gas from entering the interior of the housing 80 and affecting the internal components of the housing 80.

[0283] Furthermore, the first connection port 642 is located 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 sloping towards the first connection port 642. Thus, the water flowing downwards from the guide wall 66 can more easily flow out of the primary water vapor separation chamber K through the first connection port 642. As mentioned earlier, both the water vapor separation inlet 631 and the first connection port 642 are located on the bottom wall 633 of the primary water vapor separation chamber, but the water vapor separation inlet 631 is positioned higher 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.

[0284] Furthermore, as mentioned earlier, the water vapor separator outlet 62 can communicate with the interior of the filter housing 42, allowing the steam discharged from the water vapor separator outlet 62 to be released into the atmosphere through the filter housing 42. Alternatively, as another possible implementation, the water vapor separator 60 can be partially housed within the housing 80, with both the water vapor separator outlet 61 and the water vapor separator outlet 62 located on the outside of the housing 80. This arrangement facilitates the escape of steam discharged from the water vapor separator outlet 62 to the outside of the housing.

[0285] In addition, in this embodiment, the cross-sectional area of ​​the water vapor separation outlet 62 is greater than or equal to 22 mm. 2 Because the steam discharged from the water vapor separator outlet 62 condenses upon contact with the outside air, and this condensate can flow directly into an external water cup, if the cross-sectional area of ​​the water vapor separator outlet 62 is too small, the condensate will form a water film as it passes through it, hindering the exhaust process. This causes steam to be discharged from the water vapor separator outlet 61 along with the water flow, resulting in flow interruption and jetting. When the cross-sectional area of ​​the water vapor separator outlet 62 is greater than or equal to 22 mm², the steam will condense. 2 This can prevent this situation from occurring.

[0286] Furthermore, the cross-sectional area of ​​the first connection port 642 is greater than or equal to 22 mm². 2 This prevents water from forming a water film due to the small cross-sectional area when it flows out of the first water vapor separation chamber M through the first connection port 642, which would otherwise cause poor drainage.

[0287] The following reference Figure 28 Explain the working process of the water-vapor separator 60 during water cut-off operation.

[0288] exist Figure 28 In this paper, the water cut-off process of the water vapor separator is divided into six states.

[0289] State (a) is the water level state during water production.

[0290] State (b) corresponds to the instant when water intake stops. The water flowing out of the first-stage water vapor separation chamber K will be flushed out of the third guide pipe 655 due to the inertia of the water flow and the adhesion properties of the water, so that the water level in the third guide pipe 655 is lower than the water level in the retention tank N when it is full of water.

[0291] State (c) is that as time goes on, the water in the third guide pipe 655 gradually becomes stable, and some of the water in the retention tank N returns to the third guide pipe 655, so that the water level in the third guide pipe 655 is the same as the water level in the retention tank N, and thus the water level in the retention tank N is lower than the top of the baffle wall 654.

[0292] In state (d), if residual water droplets in the primary water vapor separation chamber K drip into the secondary water vapor separator 65, the water levels in the retention tank N and the third guide pipe 655 will rise accordingly. However, due to the viscosity of water, it will adhere to the side of the stop wall 654 near the retention tank N. That is, the water in the retention tank N will not cross the stop wall 654, so no water droplets will fall from the water vapor separation outlet 61. In this way, the effect of quickly sealing the water when stopping water intake is achieved.

[0293] State (e) corresponds to a schematic diagram of the stop wall 654 blocking the dripping water in the retention tank.

[0294] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0295] The embodiments described above are merely examples illustrating several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
