Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purification, in particular to a water purifier. BACKGROUND

[0002] With the improvement of people's living standards, more and more people pursue high-quality life, and the water purifier is undoubtedly one of the best choices. The water purifier in the related art usually includes a heater and a water-vapor separator. The filtered water is heated by the heater and then separated by the water-vapor separator before being provided to the user. However, the water-vapor separator in the related art has the problem of poor separation effect of steam. The water flowing out of the water outlet of the water-vapor separator often contains a large amount of steam. In order to avoid this problem, the water purifier in the related art usually controls the outlet water temperature at about 93 DEG C to reduce the content of steam in the outlet water. However, this will cause the water purifier to have the problem of insufficiently high outlet water temperature. SUMMARY

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

[0069] Figure 1 The water purifier 100 of the present application is described below with reference to the accompanying drawings. Figure 2 The water purifier 100 of the present application is described below with reference to the accompanying drawings. Figure 3 The water purifier 100 of the present application is described below with reference to the accompanying drawings. Figure 4 The water purifier 100 of the present application is described below with reference to the accompanying drawings.

[0070] Referring to Figure 1 , Figure 2 , Figure 3 The water purifier 100 of the present application is described below with reference to the accompanying drawings.

[0071] The water purifier 100 comprises a housing 80, a filter 40, a communicating device 30, a purified water tank 20, a liquid level box 10, a water pump 50, a heater 55 and a water vapor separator 60. The filter 40 is in communication with a communicating device cavity C of the communicating device 30, the communicating device 30 is in communication with the purified water tank 20 and the liquid level box 10 respectively, the water pump 50 is in communication with the communicating device cavity C of the communicating device 30 and the heater 55 respectively, so that the water pump 50 can pump the water in the liquid level box 10 and the purified water tank 20 to the heater 55 through the communicating device 30. The heater 55 is in communication with the water vapor separator 60. It should be noted that the communicating device 30 and the purified water tank 20 are detachably connected.

[0072] 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.

[0073] 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.

[0074] The heater 55 is used to heat the purified water, and the water vapor separator 60 is used to separate the water vapor in the heated purified water. The water vapor separator 60 is provided with a water vapor separation outlet 61, which forms the water intake of the water purifier 100.

[0075] 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.

[0076] 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.

[0077] The following is a detailed description of each part of the water purifier 100 with reference to the accompanying drawings.

[0078] 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.

[0079] 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.

[0080] The bearing 81 is configured as a water collecting box 85 which is detachably arranged outside the shell 80, and the top wall of the water collecting box 85 is provided with a water collecting hole 82 which is communicated to the inside, and the water purifying tank 20 is borne on the top wall of the water collecting box 85.

[0081] In this way, the water purifying tank 20 is detachably arranged outside the shell 80, so that the user can directly unload the water purifying tank 20 to take water when a large amount of water is needed. In addition, the water purifying tank 20 can be conveniently unloaded for cleaning and other maintenance operations.

[0082] In addition, in combination with Figure 1 and Figure 2 , part of the structure of the water vapor separator 60 penetrates through the shell 80 and extends outside the shell 80, and the water vapor separation outlet 61 is located on the part of the water vapor separator 60 which extends outside the shell 80. In this way, it is convenient for the user to take water from the water vapor separation outlet 61 outside the shell 80. Exemplarily, an avoiding opening 8731 can be formed on the front panel 873, and the water vapor separation outlet 61 extends to the outside of the shell 80 through the avoiding opening 8731.

[0083] In the embodiment of the present application, referring to Figure 4 , the water level sensor 12 is configured as a float sensor, and the water level sensor 12 includes a first float 121 and a second float 122. The liquid level box 10 is sequentially provided with a first upper baffle 123, a first lower baffle 124, a second upper baffle 125 and a second lower baffle 126 along the height direction of the liquid level box 10, the first float 121 is located between the first upper baffle 123 and the first lower baffle 124, and the second float 122 is located between the second upper baffle 125 and the second lower baffle 126.

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

[0085] In this way, whether detecting a high liquid level or a low liquid level, the stroke of the corresponding float is relatively short, and compared with the scheme of only arranging one float, the situation that the float is easily stuck and thus causes inaccurate detection results or the failure of the float is avoided when the float is at different liquid levels.

[0086] In the embodiment of the present application, the water purifier 100 further comprises a controller (not shown) electrically connected with the water level sensor 12 and the booster pump, and the controller is configured to control the booster pump to stop working when the liquid level in the liquid level box 10 is at the high liquid level, thereby stopping water production; control the booster pump to start working when the liquid level in the liquid level box 10 is lower than the high liquid level, thereby producing water; and control the water pump 50 to stop working when the liquid level in the liquid level box 10 is at the low liquid level, thereby stopping water output.

[0087] In the embodiment of the present application, the water purifier 100 further comprises an air exhaust member 70.

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

[0089] As described above, the communicating vessel 30 is configured with a communicating vessel inner cavity C in communication with the water purifying tank 20, the liquid level box 10 and the first chamber E, respectively. Exemplarily, the water filtered by the filter 40 can be sequentially input into the air exhaust member 70 and the communicating vessel 30, and flow into the liquid level box 10 and the water purifying tank 20 through the communicating vessel inner cavity C. In addition, the communicating vessel 30 is also in communication with the filter outlet on the filter body 43 described later and the water outlet of the water purifier.

[0090] By arranging the air exhaust member 70, the air in the communicating vessel 30 and the air entering the filter 40 can be exhausted through the air exhaust member 70 when water is initially produced, in other words, the water filtered from the filter 40 is directly exhausted through the air exhaust member 70, thereby reducing the amount of gas entering the communicating vessel 30, which not only solves the problem of water jetting of hot water, but also solves the problems of unstable water form of the water outlet of the water purifier 100 and slow water output speed, and further facilitates smooth flow of water.

[0091] Continuing to refer to Figure 3 , the liquid level box 10 is provided with a gas outlet 13 in communication with the atmosphere; the air exhaust member 70 is arranged on the liquid level box 10, and the first chamber E is in communication with a liquid level box inner cavity A of the liquid level box 10 to communicate with the atmosphere through the gas outlet 13. In this way, the liquid level box 10 and the air exhaust member 70 can be integrally arranged, thereby reducing the number of components and saving installation steps.

[0092] Further, referring to Figure 5 , the air exhaust member 70 is arranged on the outer side wall of the liquid level box 10, and the air exhaust member 70 and the side wall of the liquid level box 10 facing each other are both provided with a communication port 14 in communication with each other to enable the first chamber E to communicate with the liquid level box inner cavity A. By communicating the first chamber E with the liquid level box inner cavity A, the liquid level box 10 is in communication with the atmosphere, and in this way, the first chamber E of the air exhaust member 70 is in communication with the atmosphere through the liquid level box inner cavity A.

[0093] For the communication mode between various components, combined withFigure 3 、 Figure 4 、 Figure 5 For example, the exhaust member 70 can be provided with an exhaust member liquid inlet 72 and an exhaust member liquid outlet 73, the communication vessel 30 can be provided with a communication vessel liquid inlet 33 communicating with the communication vessel cavity C, the exhaust member liquid inlet 72 communicates with the filter liquid outlet through a first pipeline 101, and the exhaust member liquid outlet 73 communicates with the communication vessel liquid inlet 33 of the communication vessel 30 through a second pipeline 102.

[0094] The communication port 14 on the exhaust member 70 and the liquid level box 10 is arranged at a height higher than the arrangement height of the exhaust member liquid inlet 72 relative to the bottom wall of the liquid level box 10. In this way, water entering the exhaust member 70 from the exhaust member liquid inlet 72 can be prevented from entering the liquid level box 10 from the communication port 14.

[0095] Referring to Figure 3 Further, the communication vessel liquid inlet 33 communicates with the filter liquid outlet of the filter 40 through the exhaust member 70, the diameter of the communication vessel liquid inlet 33 is greater than 6 mm, and the inner diameter of the second pipeline 102 is greater than 6 mm.

[0096] When the diameter of the communication vessel liquid inlet 33 or the inner diameter of the second pipeline 102 connected to the communication vessel liquid inlet 33 is less than 6 mm, the process of air in the communication vessel 30 entering the exhaust member 70 through the second pipeline 102 is hindered, and the exhaust member 70 is prone to poor exhaust, which makes the water entering the communication vessel 30 from the exhaust member 70 unstable and smooth, and causes water accumulation in the exhaust member 70 to directly enter the liquid level box 10 from the communication port 14, resulting in a high water level in the liquid level box 10, which affects the judgment of the water level in the water purifier 20.

[0097] Figure 6 The structure diagram of the filter 40 in the water purifier 100 provided by the embodiment of the present application is shown.

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

[0099] The air outlet 13 is in communication with the inside of the filter shell 42 of the filter 40, so that the liquid level box 10 is in communication with the atmosphere, and the clean water tank 20 is also in communication with the atmosphere. Therefore, according to the principle of the communicating vessel, the water level in the liquid level box 10 and the water level in the clean water tank 20 can be kept in a state of being substantially equal to each other, so that the water level in the liquid level box 10 can accurately reflect the water level in the clean water tank 20.

[0100] The liquid level box 10 (the air outlet 13) is in communication with the inside of the filter 40 (i.e. the filter cavity 44 in the inside of the filter shell 42) through the third pipeline 103.

[0101] Further, the liquid level box 10 comprises a box body 15 and a box cover 16 sealingly arranged on the box body 15, and the air outlet 13 is arranged on the box cover 16.

[0102] In a specific implementation, as described above, the filter shell 42 is provided with a filter shell air inlet 41 in communication with the filter cavity, and the two ends of the third pipeline 103 are connected to the air outlet 13 and the filter shell air inlet 41, respectively, so that the liquid level box 10 is in communication with the atmosphere.

[0103] It can be understood that the filter cavity is necessarily provided with an opening for accessing the filter body 43, and the filter cavity is also in communication with 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 pipeline 103, the appearance of the whole water purifier 100 is more beautiful without adding a new opening on the shell 80 of the water purifier 100.

[0104] Exemplarily, the filter shell 42 is provided with a filter extension pipe 421 in communication with the inside of the filter shell 42 through the filter shell air inlet 41, the box cover 16 is provided with a liquid level box extension pipe 161 at a position corresponding to the air outlet 13, and the two ends of the third pipeline 103 are connected to the filter extension pipe 421 and the liquid level box extension pipe 161, respectively. In this way, the two ends of the third pipeline 103 are connected to the filter shell 42 and the liquid level box 10.

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

[0106] In addition, as described above, the water pump 50 is in communication with the communicating vessel 30 and the heater 55 respectively, and is used to pump the water in the liquid level box 10 and the clean water tank 20 to the heater 55 through the communicating vessel 30.

[0107] The water vapor separator 60 includes the water vapor separation gas outlet 62 and the aforementioned water vapor separation water outlet 61, and the water vapor separation gas outlet 62 is in communication with the inside of the filter shell 42. In this way, the steam discharged from the water vapor separation gas outlet 62 can be discharged to the atmosphere through the filter shell 42.

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

[0109] In specific implementation, the filter body 43 includes a first-stage filter 431, a second-stage filter 432 and a third-stage filter 433 connected in sequence, the filter inner cavity 44 includes a first-stage filter inner cavity 441, a second-stage filter inner cavity 442 and a third-stage filter inner cavity 443 connected in communication, the first-stage filter 431 is accommodated in the first-stage filter inner cavity 441, the second-stage filter 432 is accommodated in the second-stage filter inner cavity 442, and the third-stage filter 433 is accommodated in the third-stage filter inner cavity 443, and the gas outlet 13 is in communication with the first-stage filter inner cavity 441.

[0110] By setting the filter body 43 as the first-stage filter 431, the second-stage filter 432 and the third-stage filter 433 connected in sequence, the filtration effect can be better.

[0111] Further, the water purifier 100 further includes a booster pump, which is used to pump the water to be purified into the filter body 43, and the water source is purified in the filter body 43. By setting the booster pump as a power source for water production of the purifier, it can be applied to various types of water sources, such as water sources in water storage tanks in daily life, in addition to water sources with certain water pressure such as tap water pipes.

[0112] In the embodiment of the present application, the filter 40 is combined with the liquid level box 10 to form a filter assembly. Figure 3 , Figure 4As mentioned above, the water pump 50 is in communication with the communicating device 30 and the heater 55 respectively, and is used to pump the water in the water level box 10 and the purified water tank 20 to the heater 55 through the communicating device 30. The water vapor separator 60 is in communication with the heater 55, and is used to separate the water vapor heated by the heater 55.

[0113] In this way, when the user takes water, the water pump 50 pumps water from the communicating device 30, and the water in the water level box 10 and the purified water tank 20 flows into the water pump 50 at the same time, and the water in the water pump 50 flows into the heater 55, and then flows into the water vapor separator 60 through the heater 55, and then flows out of the water vapor separator 60.

[0114] Continuing to refer to Figure 6 Further, the water vapor separation outlet 62 is in communication with the third pipeline 103 through the fourth pipeline 104. In this way, the steam separated by the water vapor separation outlet 62 can also be discharged to the atmosphere through the filter shell 42. The number of pipelines can also be reduced, and the structure is more compact.

[0115] As for the communication between the purified water tank 20 and the atmosphere, for example, refer to Figure 4 The purified water tank 20 includes a purified water tank body 25 and a water tank cover 26 which is openably and closably arranged on the purified water tank body 25. A gap is arranged between the purified water tank body 25 and the water tank cover 26, so that the purified water tank 20 is in communication with the atmosphere. In this way, when the user needs to take a large amount of water, the water can be taken by opening the water tank cover 26 and pouring.

[0116] Further, the water vapor separation outlet 62 is arranged at the top end of the water vapor separator 60, and the third pipeline 103 and the fourth pipeline 104 are located on the top end side of the water level box 10 and the water vapor separator 60.

[0117] In this way, the lengths of the third pipeline 103 and the fourth pipeline 104 can be set to be shorter, and in combination with the characteristics of the upward movement of the water vapor, the water vapor is more smoothly discharged.

[0118] Figure 7 A schematic view of a transverse section of the water purifier 100 provided in the embodiments of the present application.

[0119] In the embodiments of the present application, as mentioned above, the communicating device 30 is in communication with the water level box 10 and the purified water tank 20 respectively. In specific implementation, in combination with Figure 3 and Figure 7 The water level box 10 is provided with a water level box communication port 11, and the purified water tank 20 is provided with a purified water tank communication port 21. The communicating device 30 is further provided with a second communication port 31 and a first communication port 32. The second communication port 31 is connected with the water level box communication port 11, and the first communication port 32 is connected with the purified water tank communication port 21. In this way, the communication of the communicating device 30 with the water level box 10 and the purified water tank 20 is realized.

[0120] Further, referring to Figure 3 , Figure 4 , the communicating vessel 30 is further provided with a communicating vessel liquid outlet 38, which is in communication with the water outlet of the water purifier 100; the setting height of the liquid level box communication port 11 relative to the bottom of the water purifier 100 is higher than the setting height of the communicating vessel liquid outlet 38.

[0121] In this way, the liquid in the liquid level box 10 can flow out of the communicating vessel 30 more smoothly through the communicating vessel liquid outlet 38, thereby avoiding the situation that the liquid level box 10 cannot discharge liquid smoothly, water accumulates in the liquid level box 10, and the water provided to the water outlet is mixed with the accumulated water.

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

[0123] Of course, the communication between the water pump 50 and the communicating vessel 30 is realized by connecting the communicating vessel liquid outlet 38 with the inlet of the water pump 50 through a pipe, and the outlet of the water pump 50 is further connected with the heater 55 through another pipe to deliver the water in the communicating vessel 30 to the heater 55. The water pump 50 can be connected to the outer wall of the air exhaust member 70 by screws or other fasteners.

[0124] Further, the setting height of the communicating vessel liquid inlet 33 relative to the bottom of the water purifier 100 is higher than the setting heights of the liquid level box communication port 11, the water tank communication port 21, and the communicating vessel liquid outlet 38. The communicating vessel liquid inlet 33 can be arranged at the topmost position of the communicating vessel 30. Therefore, the water in the communicating vessel 30 from the communicating vessel liquid inlet 33 can smoothly enter the liquid level box 10 and the water tank 20.

[0125] Figure 8 Another structure of the communicating vessel 30 in the water purifier 100 provided by the embodiments of the present application is shown in the schematic view.

[0126] Referring to Figure 8 , because the water making and water taking of the water purifier 100 both pass through the communicating vessel 30, in the water making process, because the volume of the communicating vessel 30 is small, air cannot be smoothly discharged. It can be considered that the communicating vessel cavity C is in communication with the filter liquid outlet of the filter 40, for example, the filter liquid outlet of the filter 40 can be connected with the communicating vessel liquid inlet 33 through a pipe (not shown). At this time, the communicating vessel liquid inlet 33 can be in communication with the air exhaust member 70 at the same time, or only in communication with the filter liquid outlet and not in communication with the air exhaust member 70.

[0127] Further, the air exhaust part 701 which communicates with the atmosphere is arranged on the communicating vessel 30, and the air exhaust part 701 communicates with the communicating vessel inner cavity C, so that in the process of water production and water taking of the water purifier 100, the air is smoothly exhausted from the communicating vessel 30, the water flow is smooth, and the water level of the water purifier 20 and the float box can be in a real-time balanced state. When the communicating vessel inlet 33 only communicates with the filter outlet, but does not communicate with the air exhaust part 70, the water filtered by the filter 40 does not pass through the air exhaust part 70, but directly enters the communicating vessel inner cavity C from the communicating vessel inlet 33, and exhausts through the air exhaust part 701.

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

[0129] It should be noted that in another possible implementation, the communicating vessel inlet 33 can simultaneously communicate with the filter outlet and the air exhaust part 70, and the water in the filter 40 can partially enter the communicating vessel 30 through the air exhaust part 70, or can partially directly enter the communicating vessel 30 through the pipeline which communicates with the communicating vessel inlet 33, and at this time, the air can be exhausted through the air exhaust part 70 and the air exhaust part 701 simultaneously.

[0130] The working process of the water purifier 100 of the embodiment of the present application will be described below in combination with Figure 3 、 Figure 7 .

[0131] When the user needs to take the purified water, as shown by the dashed arrow in Figure 3 , the water pump 50 works, the purified water in the water purifier 20 enters the communicating vessel inner cavity C through the water purifier communicating port 21 and the first communicating port 32, and the purified water in the liquid level box 10 enters the communicating vessel inner cavity C through the liquid level box communicating port 11 and the second communicating port 31. Under the driving of the water pump 50, the purified water in the communicating vessel inner cavity C enters the water pump 50 through the communicating vessel outlet 38, and then enters the heater 55 which communicates with the water pump 50. When the purified water enters the heater 55, the heater 55 works to heat the purified water, and the purified water will not be heated when the heater 55 does not work. The water entering the heater 55 finally enters the water vapor separator 60. After the heated purified water is subjected to water vapor separation through the water vapor separator 60, the purified water flows out from the water vapor separation outlet 61, and if the purified water is not heated in the heater 55, it also directly flows out from the water vapor separation outlet 61. In this process, the water pump 50 is the driving source of the whole cycle.

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

[0133] In the embodiments of the present application, in combination with Figure 3 and Figure 7 , the volume of the purified water tank inner cavity B of the purified water tank 20 is greater than the volume of the liquid level box inner cavity A of the liquid level box 10. As described above, the water filtered by the filter 40 can flow into the liquid level box 10 and the purified water tank 20 through the communicating vessel inner cavity C.

[0134] Further, in combination with Figure 4 and the later described Figure 9 , the minimum cross-sectional area of the first communicating passage P for the communication between the purified water tank communicating port 21 and the communicating vessel inner cavity C is greater than the minimum cross-sectional area of the second communicating passage Q for the communication between the liquid level box communicating port 11 and the communicating vessel inner cavity C.

[0135] Because the volume of the purified water tank inner cavity B of the purified water tank 20 is greater than the volume of the liquid level box inner cavity A of the liquid level box 10, if the water in and out speed of the purified water tank 20 is the same as that of the liquid level box 10, it is easy to appear that the liquid level in the purified water tank 20 is temporarily higher than that in the liquid level box 10 when the water purifier 100 is used. In the present application, by making the minimum cross-sectional area of the first passage P greater than the minimum cross-sectional area of the second passage Q, in this way, the water in and out amount of the purified water tank 20 per unit time is greater than that of the liquid level box 10 per unit time, that is, the water out speed of the larger volume purified water tank 20 is greater than that of the smaller volume liquid level box 10, which can compensate for the temporary liquid level difference caused by the volume difference, so that the liquid levels of the purified water tank 20 and the liquid level box 10 are kept consistent in real time when the water purifier 100 is used, and the water level detected by the water level detector in the liquid level box 10 can always truly reflect the water level in the purified water tank 20, avoiding the repeated water making situation.

[0136] Further, the communicating vessel 30 is provided with a communicating vessel connecting pipe 34 in communication with the communicating vessel inner cavity C, and the communicating vessel connecting pipe 34 corresponds to the position of the first communicating port 32.

[0137] The water purifying tank 20 is provided with a water purifying tank connecting pipe 22 corresponding to the position of the water purifying tank communication port 21, and the water purifying tank connecting pipe 22 is in communication with the water purifying tank inner cavity B of the water purifying tank 20; when the water purifying tank connecting pipe 22 is carried on the carrier 81, it can be partially inserted into the communication device connecting pipe 34 to make the communication device inner cavity C and the water purifying tank inner cavity B in communication.

[0138] The part of the communication device connecting pipe 34 that is not inserted by the water purifying tank connecting pipe 22 and the water purifying tank connecting pipe 22 together define a first communication channel P, and the minimum cross-sectional area of the first communication channel P is located on the part of the communication device connecting pipe 34 that is not inserted by the water purifying tank connecting pipe 22.

[0139] Further, the communication device 30 is provided with a communication device insertion pipe 341 in communication with the communication device inner cavity C, and the communication device insertion pipe 341 corresponds to the position of the second communication port 31.

[0140] The liquid level box 10 is provided with a liquid level box insertion pipe 17 in communication with the liquid level box inner cavity A; the liquid level box insertion pipe 17 is inserted into the communication device insertion pipe 341.

[0141] The part of the communication device insertion pipe 341 that is not inserted by the liquid level box insertion pipe 17 and the liquid level box insertion pipe 17 together define a second communication channel Q, and the minimum cross-sectional area of the second communication channel Q is located in the liquid level box insertion pipe 17.

[0142] In the embodiments of the present application, the cross-sectional area S1 of the water purifying tank inner cavity B along the height direction of the water purifier 100, the minimum cross-sectional area S2 of the first communication channel P, the cross-sectional area S3 of the liquid level box inner cavity A along the height direction of the water purifier 100, and the minimum cross-sectional area S4 of the second communication channel Q satisfy:

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

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

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

[0146] In this way, the water level in the water purifying tank 20 and the liquid level box 10 can always be completely consistent when the water purifier 100 is in use, 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 purifying tank 20 in real time, and the repeated water making situation can be avoided.

[0147] 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.

[0148] 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.

[0149] 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.

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

[0151] 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 .

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

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

[0157] Further, as mentioned before, the communicating vessel 30 is provided with the communicating vessel connecting pipe 34 which communicates with the communicating vessel inner cavity C, and the communicating vessel connecting pipe 34 is arranged at the position corresponding to the first communicating port 32. In the specific implementation, the communicating vessel 30 is at least partially arranged in the shell 80, and the communicating vessel connecting pipe 34 penetrates from the shell 80 to the outside of the shell 80 and extends to the bearing side of the bearing member 81.

[0158] In this way, most of the communicating vessel 30 is accommodated in the shell 80, and only the communicating vessel connecting pipe 34 used for connecting with the water purifier 100 extends to the outside of the shell 80, and the clean water tank 20 can be placed on the bearing member 81 outside the shell 80, which is convenient for the user to take.

[0159] Correspondingly, the clean water tank 20 is provided with the clean water tank connecting pipe 22 which communicates with the clean water tank inner cavity B of the clean water tank 20, and the clean water tank connecting pipe 22 is arranged at the position corresponding to the clean water tank communicating port 21. The communicating vessel check valve 36 is located in the communicating vessel connecting pipe 34, and the clean water tank check valve 27 is arranged in the clean water tank connecting pipe 22.

[0160] The clean water tank connecting pipe 22 is configured to be capable of being inserted into the communicating vessel connecting pipe 34 when bearing on the bearing member 81 to make the communicating vessel inner cavity C and the clean water tank inner cavity B communicate. Exemplarily, when the clean water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the clean water tank check valve 27 pushes open the valve core 361 of the communicating vessel check valve to realize the water inlet and outlet of the communicating vessel 30 and the clean water tank 20.

[0161] More specifically, in combination with Figure 3 , Figure 8 The communicating vessel connecting pipe 34 is provided with the valve seat 362, and the valve core 361 of the communicating vessel check valve is elastically connected to the valve seat 362, for example, connected to the valve seat 362 through the elastic member. When the clean water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the valve core 271 of the clean water tank check valve overcomes the elastic force of the elastic member and presses against the valve core 361 of the communicating vessel check valve to open the communicating vessel check valve 36. At the same time, the valve core 361 of the communicating vessel check valve also pushes open the valve core 271 of the clean water tank check valve to open the clean water tank check valve 27. When the clean water tank connecting pipe 22 is separated from the communicating vessel connecting pipe 34, the valve core 361 of the communicating vessel check valve restores to the original state under the action of the elastic member (not shown) to close the communicating vessel connecting pipe 34. Of course, when the clean water tank connecting pipe 22 is separated from the communicating vessel connecting pipe 34, the valve core 271 of the clean water tank check valve also restores to the original state under the action of the elastic member to close the clean water tank connecting pipe 22.

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

[0163] In this way, when the clean water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the spool 271 of the clean water tank check valve can reliably abut against the spool 361 of the communicating vessel check valve, so as to smoothly open the communicating vessel check valve 36 and realize water in and out of the communicating vessel 30 to the clean water tank 20.

[0164] Figure 10 A cross-sectional structure schematic view of the first communicating port 32 and the clean water tank communicating port 21 separated from each other in the water purifier 100 provided in the embodiment of the present application; Figure 11 A partial enlarged view of U in Figure 10 A cross-sectional structure schematic view of the first communicating port 32 and the clean water tank communicating port 21 matched with each other in the water purifier 100 provided in the embodiment of the present application; Figure 12 A partial enlarged view of V in Figure 13 A cross-sectional structure schematic view of the first communicating port 32 and the clean water tank communicating port 21 matched with each other in the water purifier 100 provided in the embodiment of the present application; Figure 12 A partial enlarged view of V in Figure 14 A structure schematic view of the sealing ring 35 and the communicating vessel connecting pipe 34 matched with each other in the water purifier 100 provided in the embodiment of the present application. It should be noted that, in Figure 12 and Figure 13 , the structure of the clean water tank check valve 27 is omitted for easy observation.

[0165] In the embodiment of the present application, refer to Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , the communicating vessel connecting pipe 34 is provided with the sealing ring 35, the two axial ends of the sealing ring 35 abut against the inner wall of the communicating vessel connecting pipe 34, and the first sealing section 353 between the two axial ends of the sealing ring 35 and the inner wall of the communicating vessel connecting pipe 34 together define the water storage cavity F; the clean water tank connecting pipe 22 is configured to be capable of being inserted into the communicating vessel connecting pipe 34 when being carried on the carrier 81 to make the communicating vessel cavity C and the clean water tank cavity B communicate; and make the first sealing section 353 elastically deform towards the radial outer side of itself to extrude the water in the water storage cavity F to the communicating vessel connecting pipe 34; and capable of elastically resetting the first sealing section 353 towards the radial inner side of itself when being separated from the communicating vessel connecting pipe 34 to absorb the water in the communicating vessel connecting pipe 34 to the water storage cavity F.

[0166] In the above scheme, the first sealing section 353 between the axial two end portions of the sealing ring 35 and the inner wall of the communicating device connecting pipe 34 jointly define a water storage cavity F, which has a certain water storage capacity. Since the purified water tank connecting pipe 22 can be elastically reset to the radial inner side of the first sealing section 353 when it is separated from the communicating device connecting pipe 34, water in the communicating device connecting pipe 34 can be absorbed into the water storage cavity F. Therefore, when the purified water tank 20 is taken by the user and the purified water tank connecting pipe 22 is separated from the communicating device connecting pipe 34, even if water in the communicating device 30 flows into the communicating device connecting pipe 34, it will be partially or completely absorbed by the water storage cavity F, thereby reducing the problem of water flowing into the communicating device connecting pipe 34 due to the instantaneous separation of the purified water tank connecting pipe 22 and the communicating device connecting pipe 34 when the purified water tank 20 is taken.

[0167] Continuing to refer to Figure 11 and Figure 13 , further, the end portion of the axial two end portions of the sealing ring 35 toward the purified water tank 20 is defined as the first end portion 351, and the end portion away from the purified water tank 20 is defined as the second end portion 352;

[0168] The first end portion 351 is provided with an annular flange portion 3511, and the flange portion 3511 and the outer peripheral surface of the sealing ring 35 define a flange portion mounting groove G. The end portion of the communicating device connecting pipe 34 toward the purified water tank 20 is clamped into the flange portion mounting groove G, so that the first end portion 351 partially contacts the inner wall of the communicating device connecting pipe 34.

[0169] In this way, the first end portion 351 of the sealing ring 35 covers the end portion of the communicating device connecting pipe 34 toward the purified water tank 20, which can prevent water in the water storage cavity F from leaking from the first end portion 351, that is, from the side toward the purified water tank 20.

[0170] Further, the second end portion 352 is provided with an annular protrusion portion 3521, which abuts against the inner wall of the communicating device connecting pipe 34. The protrusion portion 3521, the outer peripheral surface of the first sealing section 353, and the flange portion 3511 jointly define a water storage groove, and the water storage groove and the inner wall of the communicating device connecting pipe 34 jointly define the water storage cavity F.

[0171] In this way, the water storage cavity F is formed by providing the water storage groove on the sealing ring 35, which has a relatively simple structure and is easy to process. Moreover, it is also convenient for the purified water tank connecting pipe 22 to be inserted into the inside of the sealing ring 35, and the inner peripheral surface of the sealing ring 35 is pressed outward along the radial direction, so that the first sealing section 353 is elastically deformed outward along the radial direction, so as to press the water in the water storage cavity F into the communicating device connecting pipe 34.

[0172] In the embodiments of the present application, continuing to refer to Figure 11The inner circumferential surface of the first sealing section 353 is protruded with at least two annular interference fit portions 3531, which are arranged at intervals along the axial direction of the sealing ring 35 and are used to interfere fit with the water tank connecting pipe 22.

[0173] 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 avoid water leakage between the water tank connecting pipe 22 and the communicating vessel connecting pipe 34.

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

[0175] In the direction from the first end portion 351 to the second end portion 352, i.e. the direction in which the water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the water tank connecting pipe 22 first contacts the interference fit portion 3531 with a higher protruding height during the above insertion process, so that water can be sealed as soon as possible to avoid water leakage. Continue to insert, the water tank connecting pipe 22 cooperates with the interference fit portion 3531 with a lower protruding height, and the interference amount is relatively small, which can reduce the insertion difficulty of the water tank connecting pipe 22 and increase the insertion feel.

[0176] In the embodiments of the present application, with reference to Figure 14 , the number of interference fit portions 3531 is two, and the outer circumferential surface of the sealing ring 35 is provided with a support protrusion 354 between the regions corresponding to the two interference fit portions 3531.

[0177] In this way, when the water tank connecting pipe 22 is inserted into the sealing ring 35, the interference fit portion 3531 is elastically deformed towards the inner wall of the communicating vessel connecting pipe 34 under the pressure of the water tank connecting pipe 22, and the support protrusion 354 first contacts the inner wall of the communicating vessel connecting pipe 34. At this time, the outer circumferential surface of the sealing ring 35 has two avoidance spaces corresponding to the two interference fit portions 3531 and the inner wall of the communicating vessel connecting pipe 34, and the existence of the two avoidance spaces allows the two interference fit portions 3531 to still have room for elastic deformation towards the radial outside or the radial inside, preventing the problem of the water tank connecting pipe 22 not fitting with the sealing ring 35 due to dimensional tolerance, and also solving the problem of poor insertion feel of the water tank connecting pipe 22.

[0178] Further, the number of interference fit portions 3531 is two, and the outer circumferential surface of the sealing ring 35 is provided with an avoidance groove H corresponding to each of the two interference fit portions 3531; the groove depth of the avoidance groove H corresponding to the interference fit portion 3531 with a higher protruding height is greater than the groove depth of the avoidance groove H corresponding to the interference fit portion 3531 with a lower protruding height.

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

[0180] In combination Figure 3 , Figure 9 and Figure 13 , when the water purifying tank connecting pipe 22 of the water purifying tank 20 is inserted into the communicating vessel connecting pipe 34, the valve core 271 of the water purifying tank check valve abuts against the valve core 361 of the communicating vessel check valve 36, the communicating vessel check valve 36 is opened, and the water purifying tank cavity B of the water purifying tank 20 and the communicating vessel cavity C of the communicating vessel 30 are communicated. At this time, the water purifying tank connecting pipe 22 is inserted into the inside of the sealing ring 35, and the first sealing section 353 is pushed towards the radial outside of the sealing ring 35, so that the outside wall of the first sealing section 353 abuts against the inner wall of the communicating vessel connecting pipe 34, and the water storage cavity F is squeezed. When the water purifying tank connecting pipe 22 is pulled out of the communicating vessel connecting pipe 34, part of the water flows out from the valve core 361 of the communicating vessel check valve. At this time, the communicating vessel connecting pipe 34 no longer squeezes the first sealing section 353, the sealing ring 35 returns to its original state, the water storage cavity F returns to its original state, and the part of the water flowing into the communicating vessel connecting pipe 34 is squeezed into the water storage cavity F due to the atmospheric pressure and temporarily stored in the water storage cavity F.

[0181] Figure 15 A structure diagram of connection between the carrier 81 and the shell 80 in the water purifier 100 provided in the embodiments of the present application.

[0182] In the embodiments of the present application, with reference to Figure 15 As described above, the carrier 81 is detachably connected to the shell 80, for example, to the front panel 873, the carrier 81 is configured with the water collecting cavity D, and the top wall of the carrier 81 is provided with the water collecting hole 82 communicating with the water collecting cavity D, and the water purifying tank 20 is carried on the top wall of the carrier 81.

[0183] In this way, the water leaking from the connection between the water purifying tank 20 and the communicating vessel 30 can enter the water collecting cavity D through the water collecting hole 82. Alternatively, the user can also place a water cup on the carrier 81, and the water outside the water cup and the water purifying tank 20 can also be poured into the water collecting cavity D through the water collecting hole 82.

[0184] Further, the outer wall of the shell 80 is provided with the water guide part 83, and the carrier 81 is detachably connected to the shell 80 through the plug-in cooperation with the water guide part 83.

[0185] The water guide part 83 has a guide surface 831, the guide surface 831 is provided with a guide hole 832 communicating with the water collecting cavity D, and the guide surface 831 is configured to guide the water in the communicating vessel connecting pipe 34 to the guide hole 832.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] 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.

[0196] Reference Figure 16 , Figure 17 , Figure 18 , Figure 19 In 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.

[0197] 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.

[0198] Combination Figure 18 and Figure 19The sterilization unit 90 comprises a lampshade 91, a lampshade positioning assembly 92 and a sterilization lamp 96. The lampshade positioning assembly 92 comprises a ring-shaped first positioning member 93, a first sealing ring 94 and a second sealing ring 95. The lampshade 91 is located in the first mounting groove 29, and the head of the lampshade 91 is exposed into the water purifying tank 20 through the first mounting opening 291. The first positioning member 93 is sleeved on the outer circumferential side of the lampshade 91. The first sealing ring 94 is sealingly arranged between the first positioning member 93 and the side groove wall of the first mounting groove 29. The second sealing ring 95 is sealingly arranged between the first positioning member 93 and the outer circumferential side of the lampshade 91. In specific implementation, for example, the first sealing ring 94 is interference-fitted between the first positioning member 93 and the side groove wall of the first mounting groove 29. The second sealing ring 95 is interference-fitted between the first positioning member 93 and the outer circumferential side of the lampshade 91.

[0199] The sterilization lamp 96 is arranged on the outer wall of the shell 80. When the water purifying tank 20 is carried on the carrier 81, the sterilization lamp 96 can extend into the inside of the lampshade 91.

[0200] In the above scheme, the water purifying tank 20 is detachably arranged on the carrier 81 on the outer wall of the shell 80. The user can take the water purifying tank 20 at any time according to the needs. The first positioning member 93 is sleeved on the outer circumferential side of the lampshade 91. The first sealing ring 94 is sealingly arranged between the first positioning member 93 and the side groove wall of the first mounting groove 29. The second sealing ring 95 is sealingly arranged between the first positioning member 93 and the outer circumferential side of the lampshade 91. In this way, the lampshade 91 can be mounted in the first mounting groove 29. Since the head of the lampshade 91 is exposed into the water purifying tank 20 through the first mounting opening 291, and the sterilization lamp 96 extends into the inside of the lampshade 91 when the water purifying tank 20 is carried on the carrier 81, when the water purifying tank 20 is carried on the carrier 81, the light emitted by the sterilization lamp 96 located in the inside of the lampshade 91 transmits through the lampshade 91 and irradiates into the water purifying tank 20 to sterilize the water in the water purifying tank 20.

[0201] In addition, the lampshade positioning assembly 92 comprises the first positioning member 93, the first sealing ring 94 and the second sealing ring 95 arranged on the outer side and the inner side of the first positioning member 93, respectively. The first positioning member 93 is used as a support framework, and the first sealing ring 94 and the second sealing ring 95 mainly play a deformation sealing role. Compared with the related art in which only the sealing ring 35 is used and the entire sealing ring 35 has a relatively large radial thickness, the first sealing ring 94 and the second sealing ring 95 have relatively small radial thicknesses and slow aging degree and speed, thereby improving the sealing reliability. With the increase of the use time, the possibility of water leakage is relatively small.

[0202] For example, the lampshade 91 is a light-transmitting structure. For example, the head of the lampshade 91 can extend into the water purifying tank 20 through the first mounting opening 291 to make the sterilization lamp 96 irradiate to more range of water as much as possible. The sterilization lamp 96 can be an ultraviolet sterilization lamp, for example.

[0203] In a specific implementation, the first positioning member 93 has a greater hardness than the first sealing ring 94 and the second sealing ring 95. In this way, the aging speed of the lampshade 91 mounting assembly can be further reduced, and the overall strength of the lampshade 91 mounting assembly can be improved. For example, the first positioning member 93 can be made of metal, and the first sealing ring 94 and the second sealing ring 95 can be made of rubber.

[0204] Of course, in order to increase the sealing performance, the number of the first sealing ring 94 is at least two, and the at least two first sealing rings 94 are arranged along the axial direction of the first positioning member 93. Similarly, the number of the second sealing ring 95 is at least two, and the at least two second sealing rings 95 are arranged along the axial direction of the first positioning member 93. In this way, multiple lines of defense are arranged in the axial direction of the first positioning member 93, so that the occurrence of water leakage can be minimized.

[0205] Continuing to refer to Figure 19 In the case where the number of the first sealing ring 94 and the second sealing ring 95 is multiple, in order to position in the axial direction, at least one annular second mounting groove 932 can be provided on the outer circumferential surface of the first positioning member 93, and the first sealing ring 94 is correspondingly installed in the second mounting groove 932. In this way, the first sealing ring 94 can be prevented from moving in the axial direction of the first positioning member 93.

[0206] The inner circumferential surface of the first positioning member 93 is provided with at least one annular stop portion 931, and the stop portion 931 and the inner circumferential surface 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.

[0207] In the embodiment of the present application, in combination with Figure 18 and Figure 19 The lampshade positioning assembly 92 further includes a sealing member 97, which is connected to the end of the first positioning member 93 facing the water tank 20 and is arranged on the side of the second sealing ring 95 facing the water tank 20. In this way, the second sealing ring 95 can be prevented from being separated from the gap between the first positioning member 93 and the lampshade 91.

[0208] For the connection mode of the sealing member 97 and the first positioning member 93, for example, the sealing member 97 can be provided with a clamping arm 973, and the first positioning member 93 can be provided with a clamping groove 974, and the sealing member 97 and the first positioning member 93 are connected through the clamping of the clamping arm 973 and the clamping groove 974. In this way, the first positioning member 93 and the sealing member 97 can be reliably connected as a whole.

[0209] Further, the sealing member 97 is provided with a first abutting portion 971 and a second abutting portion 972 at the end of the first positioning member 93 in the axial direction, the first abutting portion 971 is configured to abut against the second sealing ring 95, and the second abutting portion 972 is configured to abut against the end of the lampshade 91 facing the water tank 20. In this way, the second sealing ring 95 can be prevented from moving in the axial direction of the first positioning member 93, and the lampshade 91 can be prevented from being separated from the first mounting slot 29.

[0210] With reference to the foregoing Figure 18 , the germicidal lamp 96 comprises a germicidal lamp mounting frame 961 and a lamp body 962, the germicidal lamp mounting frame 961 is mounted on the outer wall of the shell 80 at a position corresponding to the first mounting port 291, and the lamp body 962 is mounted at the end of the germicidal lamp mounting frame 961 facing the water tank 20. In this way, the germicidal lamp 96 can be installed at a position corresponding to the lampshade 91.

[0211] Of course, the second mounting port 8732 is provided on the shell 80 so that the germicidal lamp mounting frame 961 penetrates the second mounting port 8732 and extends out of the shell 80.

[0212] With reference to the foregoing Figure 17 , the first mounting port 291 and the water tank communication port 21 are both located between the top and the bottom of the water tank 20, and the first mounting port 291 is located higher than the water tank communication port 21. In this way, the germicidal light emitted by the germicidal lamp 96 can cover as much water in the water tank 20 as possible.

[0213] Figure 20 is a sectional view of another structure of the water tank 20 in the water purifier 100 provided by the embodiment of the present application, Figure 21 is another angle sectional view of the water tank 20 in the water purifier 100 provided by the embodiment of the present application, Figure 22 is Figure 21 is a local enlarged view at Y.

[0214] With reference to the foregoing Figure 20 , Figure 21 , Figure 22 , in the foregoing scheme, the front panel 873 needs to be drilled and the germicidal lamp 96 needs to be installed, which affects the user's visual experience. Therefore, the germicidal unit 90 can be considered to be set in a wireless mode.

[0215] In a specific implementation, the sterilization unit 90 can include a lamp holder 98, the lamp holder 98 is arranged in the first mounting port 291 and is in sealing connection with the first mounting port 291. For example, a flange portion 982 can be arranged at a first end of the lamp holder 98, the flange portion 982 is overlapped with an edge portion of the first mounting port 291, and the flange portion 982 and the edge portion of the first mounting port 291 are provided with a third sealing ring 981. At this time, the sterilization lamp 96 can be arranged at an end of the lamp holder 98 which faces the inside of the water purifying tank 20. In this way, the sterilization lamp 96 directly extends into the inside of the water purifying tank 20, and compared with the previous solution, the irradiation range in the water purifying tank 20 is larger.

[0216] Further, with continuous reference to Figure 22 , the sterilization unit 90 further includes a second mounting member 983 which is sleeved on the lamp holder 98, the second mounting member 983 can be arranged outside the water purifying tank 20, for example, in the first mounting groove 29, and is used to apply a force to the flange portion 982 which faces outside the water purifying tank 20, so that the flange portion 982 tightly abuts the third sealing ring 981 against the inner wall of the water purifying tank 20. In actual application, the second mounting member 983 can abut against the groove bottom wall of the first mounting groove 29, and the second mounting member 983 and the lamp holder 98 can be in screw connection. At this time, the flange portion 982, the first sealing ring 94 and the second mounting member 983 are tightly abutted against the bottom of the first mounting groove 29 from the inside and outside of the water purifying tank 20 respectively.

[0217] In order to position the sterilization lamp 96, an end of the lamp holder 98 which faces the inside of the water purifying tank 20 is configured with a mounting groove, and the sterilization lamp 96 is sealingly arranged in the mounting groove.

[0218] In the embodiment of the present application, the sterilization unit 90 further includes a wireless assembly 99, the wireless assembly 99 includes a wireless sending unit 991 and a wireless receiving unit 992. The wireless sending unit 991 is arranged on the inner wall of the shell 80 and is electrically connected with a power supply circuit board (not shown) of the water purifier 100, and the wireless receiving unit 992 is arranged at an end of the lamp holder 98 which faces outside the water purifying tank 20. When the water purifying tank 20 is supported on the bearing member 81, the wireless sending unit 991 and the wireless receiving unit 992 are oppositely arranged to supply power to the sterilization lamp 96 through the wireless receiving unit 992.

It can be understood that, in order to facilitate observation of the internal structure, Figure 26 A schematic diagram showing the open state of the primary separation body cover 641 relative to the primary separation body main body 64.

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

[0221] In the water-vapor separator of the related art, there is a problem that the separation effect of steam is not good, and the water flowing out of the water-vapor separation water outlet contains a large amount of steam. In order to avoid this problem, the related art water purifier often controls the outlet water temperature at about 93℃ to reduce the content of steam in the outlet water, and therefore the related art water purifier has a problem that the outlet water temperature is not high enough.

[0222] In order to solve this problem, the structure of the water-vapor separator 60 is improved in the embodiment of the present application.

[0223] Specifically, in combination with Figure 23 , Figure 24a , Figure 25 , the water-vapor separator 60 includes a primary water-vapor separation body 63 and a secondary water-vapor separation body 65 for water-vapor separation, and the primary water-vapor separation body 63 and the secondary water-vapor separation body 65 are respectively configured with a primary water-vapor separation cavity K and a secondary water-vapor separation cavity L that are in communication with each other.

[0224] The primary water-vapor separation body 63 is provided with a water-vapor separation water inlet 631 and a first gas outlet 632 that communicate to the primary water-vapor separation cavity K, and the water-vapor separation water outlet 61 and the water-vapor separation gas outlet 62 are provided on the secondary water-vapor separation body 65 and communicate to the secondary water-vapor separation cavity L, and the water-vapor separation water inlet 631 is used to communicate with a hot water supply source.

[0225] The water-vapor separation water inlet 631 is provided on the bottom wall 633 of the primary water-vapor separation cavity, and the bottom wall 633 of the primary water-vapor separation cavity is provided with a first flow guide pipe 635 that extends towards the top wall 634 of the primary water-vapor separation cavity, and the first flow guide pipe 635 communicates to the water-vapor separation water inlet 631, and the top wall 634 of the primary water-vapor separation cavity is further provided with a drainage wall 66 that extends towards the bottom wall 633 of the primary water-vapor separation cavity, and the drainage wall 66 is arranged on the circumferential outer side of at least part of the pipe section of the first flow guide pipe 635.

[0226] The water vapor separator 60 comprises a first water vapor separation body 63 and a second water vapor separation body 65 for water vapor separation, a first water vapor separation cavity K in the first water vapor separation body 63 and a second water vapor separation cavity L in the second water vapor separation body 65 are in communication with each other, so that the water vapor mixture first enters the first water vapor separation body 63 for water vapor separation, and then enters the second water vapor separation body 65 for water vapor separation again, and the water vapor separation effect is better.

[0227] On the other hand, the water vapor separation inlet 631 is arranged on the bottom wall 633 of the first water vapor separation cavity, the bottom wall 633 of the first water vapor separation cavity is provided with a first flow guide pipe 635 extending towards the top wall 634 of the first water vapor separation cavity, so that the water vapor mixture entering the first water vapor separation cavity K from the water vapor separation inlet 631 enters the first flow guide pipe 635. In addition, the top wall 634 of the first water vapor separation cavity is also provided with a drainage wall 66 extending towards the bottom wall 633 of the first water vapor separation cavity, the drainage wall 66 is arranged on the outer side of at least part of the pipe section of the first flow guide pipe 635, so that the water vapor mixture in the first flow guide pipe 635 separates from the first flow guide pipe 635 and hits the top wall 634 of the first water vapor separation cavity, the top wall 634 of the first water vapor separation cavity can disperse the water vapor mixture, so that part of the steam in the water vapor mixture is separated from the water flow, the water flow flows down along the drainage wall 66 to the bottom of the first water vapor separation cavity K, and the steam is discharged from the first water vapor separation body 63 through the first gas outlet 632. As described above, in the case of good water vapor separation effect, the amount of steam contained in the water is small, and the outlet water temperature of the water purifier can be set to be relatively high to meet the water demand of the user.

[0228] The hot water supply source can be a heater 55, and the water outlet 551 of the heater can be connected to the water vapor separation inlet 631 through the fifth pipeline 105. Of course, in other embodiments, the water outlet 551 can also be directly connected to the water vapor separation inlet 631.

[0229] In the embodiment of the present application, the setting height of the bottom end of the drainage wall 66 towards the bottom wall 633 of the first water vapor separation cavity is lower than the setting height of the top end of the first flow guide pipe 635 towards the top of the first water vapor separation cavity K.

[0230] By making the bottom end of the drainage wall 66 lower than the top end of the first flow guide pipe 635, it can be ensured that the dispersed water flow after the water vapor mixture is dispersed by the top wall 634 of the first water vapor separation cavity can reliably fall onto the bottom wall 633 of the first water vapor separation cavity along the drainage wall 66, and will not enter the first flow guide pipe 635 from the top end of the first flow guide pipe 635.

[0231] Further, with reference to Figure 27The drainage wall 66 and the side wall 636 of the primary water-vapor separation cavity define a dispersing cavity M, and the top end side portion of the first flow guide pipe 635 extends into the dispersing cavity M.

[0232] In some embodiments, the first flow guide pipe 635 is at least partially formed as an integral part of the inner wall of the primary water-vapor separation cavity K, to facilitate the manufacturing process.

[0233] In combination with Figure 24a and Figure 27 Further, the outer wall of the primary water-vapor separation body 63 is provided with a first mounting pipe 637 coaxial with and in communication with the first flow guide pipe 635. In this way, the water-vapor mixture flowing out of the water outlet 551 of the heater can be guided into the first flow guide pipe 635.

[0234] Further, the first gas outlet 632 is arranged on the side wall 636 of the primary water-vapor separation cavity, which is provided with a second flow guide pipe 638 extending towards the top wall 634 of the primary water-vapor separation cavity, and the second flow guide pipe 638 is in communication with the first gas outlet 632. The drainage wall 66 extends between the first flow guide pipe 635 and the second flow guide pipe 638, and the top end portion of the first flow guide pipe 635 and the top end portion of the second flow guide pipe 638 are separated by the drainage wall 66.

[0235] In this way, the bottom end portion of the drainage wall 66 is actually arranged at a height lower than that of the top end portion of the second flow guide pipe 638. After the water-vapor mixture is dispersed by the top wall 634 of the primary water-vapor separation cavity, the water flow flows downward from the drainage wall 66 towards one side of the first flow guide pipe 635, and cannot enter the second flow guide pipe 638 due to the shielding of the drainage wall 66.

[0236] Similarly to the first flow guide pipe 635, the second flow guide pipe 638 is at least partially formed as an integral part of the inner wall of the primary water-vapor separation cavity K, to facilitate the manufacturing process.

[0237] In the embodiments of the present application, the outer wall of the primary water-vapor separation body 63 is provided with a second mounting pipe 639 coaxial with and in communication with the second flow guide pipe 638. In this way, the steam separated from the water-vapor can be guided out of the primary water-vapor separation cavity K. For specific implementation, reference can be made to Figure 24a The second mounting pipe 639 can be in communication with the water-vapor separation gas outlet 62 of the secondary water-vapor separation body 65 through the sixth pipeline 106.

[0238] Continuing to refer to Figure 26 and Figure 27Further, the first water-vapor separation body 63 comprises a first separation body main body 64 and a first separation body cover 641 covering the first separation body main body 64, and the guide wall 66 is arranged on the first separation body cover 641. In this way, the processing process is facilitated.

[0239] In combination Figure 24a , Figure 27 , Figure 28 The first water-vapor separation body 63 is provided with a first connecting port 642 communicating with the first water-vapor separation cavity K, the second water-vapor separation body 65 is provided with a second connecting port 651 communicating with the second water-vapor separation cavity L, and the first connecting port 642 communicates with the second connecting port 651.

[0240] The top wall 652 of the second water-vapor separation cavity is further provided with a third guide pipe 655 extending towards the bottom wall 653 of the second water-vapor separation cavity, and the third guide pipe 655 communicates with the second connecting port 651. The bottom wall 653 of the second water-vapor separation cavity is provided with a stop wall 654 extending towards the top wall 652 of the second water-vapor separation cavity, and the stop wall 654 is arranged between the circumferential outer side of the third guide pipe 655 and the water-vapor separation water outlet 61.

[0241] The top wall 652 of the second water-vapor separation cavity is further provided with a third guide pipe 655 extending towards the bottom wall 653 of the second water-vapor separation cavity, and the third guide pipe 655 communicates with the second connecting port 651. The bottom wall 653 of the second water-vapor separation cavity is provided with a stop wall 654 extending towards the top wall 652 of the second water-vapor separation cavity, and the stop wall 654 is arranged between the circumferential outer side of the third guide pipe 655 and the water-vapor separation water outlet 61.

[0242] In combination Figure 24a , Figure 28 Further, the bottom wall 653 of the second water-vapor separation cavity is constructed with a retention groove N arranged in a spaced manner with the water-vapor separation water outlet, and the bottom end of the third guide pipe 655 extends into the retention groove N.

[0243] By making the bottom end of the third flow guide pipe 655 extend into the retention groove N, i.e. the height of the bottom end of the third flow guide pipe 655 is lower than the height of the groove edge of the retention groove N. In this way, at the moment when the water taking stops, the water flowing out from the primary water vapor separation cavity K will rush out of the third flow guide pipe 655 due to the water flow inertia and the water cohesion characteristics, so that the water level in the third flow guide pipe 655 is lower than the water level in the retention groove N (filled with water). As time goes on, the water in the third flow guide pipe 655 gradually stabilizes, and part of the water in the retention groove N returns to the third flow guide pipe 655, so that the water level in the third flow guide pipe 655 is level with the water level in the retention groove N, so that the water level in the retention groove N is lower than the groove edge and is not filled. At this time, if there are residual water droplets in the primary water vapor separation cavity K falling into the secondary water vapor separation body 65, the water level in the retention groove N and the third flow guide pipe 655 will rise accordingly, but due to the water cohesion, it will adhere to the side wall of the retention groove N, i.e. the water in the retention groove N will not flow out, so that the water vapor separation outlet 61 will not have water droplets falling, in this way, the effect of quickly sealing water when stopping water taking is achieved, effectively improving the problem of water leakage at the water taking outlet of the water purifier 100.

[0244] In the related art, air is easy to enter the inner cavity of the water vapor separator 60 from the water vapor separation outlet 61, and over a long period of time, bacteria are easy to breed, and the above-mentioned inner cavity belongs to an area that cannot be cleaned by the user. In view of this, by providing the retention groove N, after stopping water taking, the bottom end of the third flow guide pipe 655 extends into the retention groove N, which plays a liquid sealing role, so that external air can be prevented from entering the inner cavity of the water vapor separator 60, especially the primary water vapor separation body 63, and the breeding of bacteria can be inhibited, so that the water output by the water vapor separator 60 is cleaner and more sanitary.

[0245] In some embodiments, the stop wall 654 and the side wall 656 of part of the secondary water vapor separation cavity define the above-mentioned retention groove N. In this way, compared with the groove on the bottom wall 653 of the secondary water vapor separation cavity, the volume of the secondary water vapor separation body 65 can be smaller.

[0246] In combination with Figure 23 and Figure 24a , further, the outer wall of the primary water vapor separation body 63 is provided with a first matching pipe 657 in communication with the first connecting port 642, and the secondary water vapor separation body 65 is provided with a first matching slot 658 in communication with the second connecting port 651, the first matching pipe 657 and the first matching slot 658 are inserted and matched to communicate the first connecting port 642 and the second connecting port 651.

[0247] It can be understood that, in order to avoid water leakage between the first matching pipe 657 and the first matching slot 658, a sealing member 660 can be arranged between the outer wall of the first matching pipe 657 and the inner slot wall of the first matching slot 658. The sealing member 660 can be an annular sealing ring, which is sleeved on the outer periphery of the first matching pipe 657 and clamped between the first matching pipe 657 and the first matching slot 658.

[0248] In this way, the primary water-vapor separation body 63 and the secondary water-vapor separation body 65 are plugged and matched, and the matching of the two is more firm. Of course, it can be understood that, referring to Figure 23 , the primary water-vapor separation body 63 and the secondary water-vapor separation body 65 can also be fixedly connected through the fastener 643, so that the connection of the two is more firm. A plurality of positioning ribs 659 can also be arranged on the outer peripheral wall of the first matching pipe 657 and spaced apart in the circumferential direction. The positioning ribs 659 abut against the slot of the first matching slot 658 to assist in positioning the plug-in matching of the first matching pipe 657 and the first matching slot 658.

[0249] In combination with Figure 23 and Figure 24a , further, the secondary water-vapor separation body 65 includes a secondary water-vapor separation main body 671 and a secondary water-vapor separation cover body 673 arranged on the secondary water-vapor separation main body 671. The first matching slot 658 is arranged at the top end side of the secondary water-vapor separation cover body 673, and the third flow guide pipe 655 is arranged at the bottom end side of the secondary water-vapor separation cover body 673 and communicates with the first matching slot 658.

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

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

[0252] In combination with Figure 24a and Figure 27 , further, the water-vapor separation air outlet 62 is arranged on the bottom wall 653 of the secondary water-vapor separation cavity and located between the water-vapor separation water outlet 61 and the stop wall 654;

[0253] The fourth flow guide pipe 672 is arranged on the bottom wall 653 of the secondary water-vapor separation cavity and extends towards the top wall 652 of the secondary water-vapor separation cavity, and the fourth flow guide pipe 672 is connected to the water-vapor separation outlet 62, and the top end of the fourth flow guide pipe 672 is spaced apart from the top wall 652 of the secondary water-vapor separation cavity.

[0254] In this way, the steam separated in the secondary water-vapor separation cavity L rises upwards, gathers at the top of the secondary water-vapor separation cavity L, enters the fourth flow guide pipe 672 from the top end of the fourth flow guide pipe 672, and flows out of the secondary water-vapor separation cavity L from the water-vapor separation outlet 62.

[0255] Further, the water-vapor separation outlet 62 is arranged on the bottom wall 653 of the secondary water-vapor separation cavity and is close to the water-vapor separation outlet 61.

[0256] In the embodiment, the fourth flow guide pipe 672 is arranged on the inner wall of the secondary water-vapor separation cover 673 and extends towards the top end of the fourth flow guide pipe 672.

[0257] In this way, the length of the fourth flow guide pipe 672 is relatively long, and the external contour size of the secondary water-vapor separation body 65 is not increased.

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

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

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

[0261] Of course, as described above, the shell 80 needs to be provided with the avoiding gap to expose part of the structure of the water-vapor separator 60 to the outside of the shell 80, for example, the water-vapor separation outlet 61 and the water-vapor separation outlet 62 need to be arranged on the outside of the shell 80, on the one hand, to facilitate water taking, and on the other hand, to facilitate the exhaust gas to not enter the inside of the shell 80 and affect the components in the inside of the shell 80.

[0262] Further, the first connecting port 642 is arranged on the bottom wall 633 of the first water-vapor separation chamber, and the bottom wall 633 of the first water-vapor separation chamber is configured as an inclined structure inclined towards the first connecting port 642. In this way, the water flow flowing downwards from the guide wall 66 can more easily flow out of the first water-vapor separation chamber K from the first connecting port 642. As mentioned above, the water-vapor separation inlet 631 and the first connecting port 642 are both arranged on the bottom wall 633 of the first water-vapor separation chamber, but the water-vapor separation inlet 631 is arranged higher than the first connecting port 642, so that the fluid flowing out of the first guide pipe 635 is more easily guided to the first connecting port 642 from the bottom wall 633 of the first water-vapor separation chamber.

[0263] In addition, as mentioned above, the water-vapor separation outlet 62 can be in communication with the interior of the filter shell 42, so that the steam discharged from the water-vapor separation outlet 62 can be discharged to the atmosphere through the filter shell 42. Of course, as another possible implementation, the water-vapor separation outlet 62 and the water-vapor separation outlet 62 can both be arranged outside the shell 80. In this way, the steam discharged from the water-vapor separation outlet 62 can be easily dissipated outside the shell.

[0264] In addition, in the embodiment of the present application, the cross-sectional area of the water-vapor separation outlet 62 is greater than or equal to 22mm 2 . Since the steam discharged from the water-vapor separation outlet 62 will form condensate water after contacting the ambient air, the condensate water can directly flow into the ambient water cup. If the cross-sectional area of the water-vapor separation outlet 62 is too small, the condensate water will form a water film when passing through the water-vapor separation outlet 62, causing poor exhaust, resulting in the phenomenon of steam being discharged from the water-vapor separation outlet 61 together with the water flow, causing water flow interruption and steam injection. When the cross-sectional area of the water-vapor separation outlet 62 is greater than or equal to 22mm 2 , this situation can be avoided.

[0265] Further, the cross-sectional area of the first connecting port 642 is greater than or equal to 22mm 2 . In this way, it can be prevented that the water flow passing through the first connecting port 642 to flow out of the first water-vapor separation chamber M forms a water film due to the small cross-sectional area, causing poor water discharge.

[0266] The working process of the water flow interruption operation of the water-vapor separation device 60 will be described below with reference to Figure 28 .

[0267] In Figure 28 , the water flow interruption process of the water-vapor separation device is divided into six states.

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

[0269] State (b) corresponds to the moment when the water taking stops, the water flowing out of the first water vapor separation cavity K will rush out of the third flow guide pipe 655 due to the water flow inertia and the water adhesion characteristics, so that the water level in the third flow guide pipe 655 is lower than the water level in the retention tank N filled with water.

[0270] State (c) is that with the increase of time, the water in the third flow guide pipe 655 gradually tends to be stable, part of the water in the retention tank N returns to the third flow guide pipe 655, so that the water level in the third flow guide pipe 655 is flat with the water level in the retention tank N, so that the water level in the retention tank N is lower than the top of the stop wall 654.

[0271] State (d) is that if there are residual water droplets in the first water vapor separation cavity K falling into the second water vapor separation body 65, the water levels in the retention tank N and the third flow guide pipe 655 will rise accordingly, but due to the viscosity of water, it will adhere to the side of the stop wall 654 close to the retention tank N, that is, the water in the retention tank N will not cross the stop wall 654, so the water vapor separation outlet 61 will not have water droplets falling, in this way, the effect of quickly stopping water when taking water is achieved.

[0272] State (e) corresponds to the schematic diagram of the stop wall 654 stopping the falling water in the retention tank.

[0273] The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0274] The above-described embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
