Description

Water purifier and UV sterilization module

[0001] This application claims priority to patent applications No. CN202311216005.3, CN202311216117.9, CN202322356914.9, and CN202322556286.9 filed with the State Intellectual Property Office of the People's Republic of China, all of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the field of water purification technology, and in particular to a water purifier and a UV sterilization module. Background Art

[0003] As people's living standards improve, more and more people pursue a high-quality life, and water purifiers are undoubtedly one of the best choices. In the water purifiers with external water purification tanks that appear in the related art, in order to sterilize the water stored in the water purification tank, most of them are equipped with a sterilization component on the water purification tank. In order to facilitate the power supply of the sterilization component, the sterilization component is usually installed on the wall of the water purification tank, with the sterilization light output end located on the inside of the water purification tank and the connection end exposed to the outside of the water purification tank. Of course, a sealing ring is usually set between the sterilization component and the wall of the water purification tank for sealing. However, as the use time increases, the sealing ring is prone to aging, resulting in water leakage at the installation site of the sterilization component.

[0004] A water purifier or a water dispenser is generally provided with a clean water tank inside, which is used to store purified water. The clean water tank is not a completely sealed structure, and a tank cover is generally provided on the top, which makes it difficult to completely isolate the clean water in the clean water tank from the air. During the long-term use of the clean water tank, bacteria will breed, which will pose a threat to the health of water users. In order to sterilize, the traditional practice is generally to use a tube or rope to hang the UV lamp module from the tank cover into the clean water tank to sterilize the water. This method has the following defects: the tube or rope hung in the clean water tank will block the tank cover, resulting in the tank cover not being completely closed. On the other hand, too many and too long tubes or wires look messy and not beautiful. In this context, the applicant is committed to developing a split UV sterilization module that does not affect the covering of the tank cover on the clean water tank and does not affect the aesthetics of the clean water tank.

[0005] In related art water purifiers with external water purification tanks, a float box connected to the water purification tank is typically installed, with a float sensor inside the float box. The water level inside the float box reflects the water level inside the water purification tank, and when the water level falls below a preset value, the water production process is activated. However, in most related art water purifiers, the water levels in the water purification tank and the float box cannot be kept consistent in real time. Often, if water accumulates or backflows in one of the float box and the water purification tank, the water level inside the float box cannot accurately reflect the water level in the water purification tank, causing the water purifier to overdub or even fail to start water production even when the water level in the water purification tank is low.

[0006] Water purifiers in related art include filters, manifolds, liquid level boxes, clean water tanks, heaters, and water pumps. During water production, filtered water from the filters is distributed through the manifolds to the liquid level boxes and clean water tanks. When a user draws water, the water pump pumps water from the liquid level boxes and clean water tanks through the manifolds into the heater, which then delivers it to the user. However, during water production, air within the manifolds, filters, and other components can enter subsequent water channels, including the heater. This can cause gas to be present at the water purifier's intake port when discharging water. This can lead to unstable water flow and slow water discharge when using cold water. When using hot water, gas trapped in the hot water can cause steam spurts, resulting in poor water discharge reliability.

[0158] The purpose of this application is to achieve a solution that does not affect the installation of the box cover on the water purification tank and does not affect the aesthetics of the water purification tank.

[0159] In order to achieve the above objectives, the technical solutions adopted in this application are as follows:

[0160] A split-type UV sterilization module includes a lampshade module and a sterilization module. The lampshade module includes a fixing ring, a transparent outer cover, a bottom cover, a first sealing ring, and a second sealing ring. The fixing ring is sleeved on the outer surface of the outer cover. The bottom cover is located at the lower end between the fixing ring and the outer cover. The first sealing ring is fixedly disposed between the fixing ring and the outer cover. The second sealing ring is located on the outer surface of the fixing ring.

[0161] The sterilization module includes a UV lamp and a fixing seat. The UV lamp is fixed on the fixing seat, and the UV lamp extends into the interior of the outer cover.

[0162] In one embodiment, the outer cover is made of quartz glass.

[0163] In one embodiment, a buckle groove is provided on the side surface of the fixing ring, and a clamping block is fixedly provided on the outer side of the bottom cover, and the clamping block is clamped in the buckle groove.

[0164] In one embodiment, a sealing groove is circumferentially formed on the outer surface of the fixing ring, and the second sealing ring is located in the sealing groove.

[0165] In one embodiment, the sterilization module further includes an inner cover and an inner silicone seat. The inner cover is fixedly disposed on the fixed seat, and an opening is provided at one end of the inner cover close to the fixed seat. The UV lamp is located inside the inner cover, and the inner silicone seat is fixedly disposed at the opening.

[0166] In one embodiment, the sterilization module further includes a wire, which passes through the fixing seat and the inner silicone seat in sequence and is electrically connected to the UV lamp.

[0167] In one embodiment, the interior of the fixing seat is filled with resin.

[0168] In one embodiment, a hanging ear is fixedly provided on the fixing seat, and a through hole is formed on the hanging ear.

[0169] The beneficial effects of the present application are as follows: the water clean tank of the present application is detachably arranged on the supporting member on the outer wall of the shell, and the user can take the water clean tank at any time according to needs. The first positioning member is sleeved on the outer peripheral side of the lampshade, and the first sealing ring is sealed between the first positioning member and the side groove wall of the first mounting groove. The second sealing ring is sealed between the first positioning member and the outer peripheral side of the lampshade. In this way, the lampshade can be installed in the first mounting groove. Since the head of the lampshade is exposed to the water clean tank through the first mounting port, and when the water clean tank is carried on the supporting member, the sterilization lamp extends into the inside of the lampshade. Therefore, when the water clean tank is carried on the supporting member, the light emitted by the sterilization lamp located on the inside of the lampshade passes through the lampshade to irradiate the water clean tank to sterilize the water stored in the water clean tank. In addition, the lampshade positioning assembly of the present application includes a first positioning member, a first sealing ring and a second sealing ring respectively arranged on the outer and inner sides of the first positioning member. The first positioning member serves as a supporting framework, and the first and second sealing rings mainly play a deformation sealing role. Compared with the related art that uses only a sealing ring and has a large radial thickness of the entire sealing ring, the radial thickness of the deformed first and second sealing rings is smaller, and the degree and speed of aging are slowed down, thereby improving the reliability of the seal. As the use time increases, the possibility of water leakage is reduced.

[0170] When installing the split-type UV sterilization module of the present application on the water clean tank, first drill a mounting hole at the corresponding position of the water clean tank, fix the lampshade module into the mounting hole on the water clean tank, and use the second sealing ring to achieve the seal between the fixing ring and the water clean tank, and use the first sealing ring to achieve the seal between the fixing ring and the outer cover. Then extend the UV lamp into the outer cover, and fix the fixing seat to the structure outside the water clean tank. When the UV lamp is working, the ultraviolet light emitted is shot into the water clean tank through the outer cover, sterilizing the water in the water clean tank. Since the lampshade module of the present application is directly embedded in the water clean tank, it will not have any effect on the box cover on the water clean tank, thereby achieving the purpose of not affecting the installation of the box cover on the water clean tank. On the other hand, since the fixing seat is arranged outside the water clean tank, the cables are routed from the outside of the water clean tank, which does not affect the aesthetics of the water clean tank. Compared with the traditional technology of hanging too many and too long pipes or wires into the water clean tank, the present application achieves the purpose of not affecting the aesthetics of the water clean tank.

[0171] The present application communicates with the atmosphere through the inside of the filter housing, that is, the inner cavity of the filter, and the air outlet is communicated with the inside of the filter housing of the filter, so that the liquid level box is communicated with the atmosphere. In addition, the clean water tank is also communicated with the atmosphere. Therefore, when the water purifier draws water from the liquid level box and the clean water tank through the communicating vessel, or the water filtered by the filter enters the liquid level box and the clean water tank through the communicating vessel, according to the principle of the communicating vessel, the water level in the liquid level box and the water level in the clean water tank can be kept roughly equal, so that the water level in the liquid level box can more accurately reflect the water level in the clean water tank. In the present application, by making the minimum cross-sectional area of ​​the first channel P larger than the minimum cross-sectional area of ​​the second channel Q, the water inlet and outlet volume of the clean water tank per unit time is larger than the water inlet and outlet volume of the liquid level box per unit time, that is, the water outlet speed of the clean water tank with a larger volume is greater than the water outlet speed of the liquid level box with a smaller volume, which can make up for the temporary liquid level height difference caused by the volume difference between the two, so that when the water purifier is in use, the liquid levels of the clean water tank and the liquid level box remain consistent in real time, so that the water level detected by the water level detector in the liquid level box can always truly reflect the water level in the clean water tank, avoiding the occurrence of reverse water duplication.

[0172] The present application provides an exhaust component, so that the air in the communication vessel during the initial water production and the air entering the filter can be discharged through the exhaust component. In other words, the water filtered out of the filter is directly exhausted through the exhaust component, reducing the amount of gas entering the communication vessel. This not only solves the problem of hot water jetting, but also solves the problems of unstable water shape and slow water outlet speed at the water purifier's water inlet, and further facilitates the smooth flow of water.

[0206] The water purifier 100 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0207] Figure 1 is a structural schematic diagram of the water purifier 100 provided in an embodiment of the present application; Figure 2 is a decomposition structural schematic diagram of the water purifier 100 provided in an embodiment of the present application; Figure 3 is a decomposition structural schematic diagram of the water purifier 100 provided in an embodiment of the present application from another angle, and Figure 4 is a cross-sectional view of the liquid level box 10 in the water purifier 100 provided in an embodiment of the present application.

[0208] 1 , 2 , and 3 , an embodiment of the present application provides a water purifier 100 for purifying water from a water source to be filtered.

[0209] The water purifier 100 includes a housing 80, a filter 40, a manifold 30, a clean water tank 20, a liquid level box 10, a water pump 50, a heater 55, and a water vapor separator 60. The filter 40 is in communication with the manifold cavity C of the manifold 30, which is in communication with the clean water tank 20 and the liquid level box 10, respectively. The water pump 50 is in communication with the manifold cavity C of the manifold 30 and the heater 55, respectively. This allows the water pump 50 to pump water from the liquid level box 10 and clean water tank 20 to the heater 55 via the manifold 30. The heater 55 is in communication with the water vapor separator 60. It should be noted that the manifold 30 and the clean water tank 20 are detachably connected.

[0210] With this arrangement, when a user draws water, the water pump 50 draws water from the communicating vessel 30 , and the water in the liquid level box 10 and the clean water tank 20 passes through the communicating vessel 30 at the same time and flows into the water pump 50 . The water in the water pump 50 flows into the heater 55 , and after being heated by the heater 55 , flows into the water vapor separator 60 and flows out of the water vapor separator 60 .

[0211] The filter 40 is connected to a water source to be purified to facilitate filtering the water source. The clean water tank 20 is used to store the filtered clean water. The liquid level box 10 is equipped with a water level sensor 12. The clean water tank 20 is connected to the liquid level box 10 through a communication vessel 30. Both the clean water tank 20 and the liquid level box 10 are open to the atmosphere. According to the communication vessel principle, the water level in the liquid level box 10 can reflect the water level in the clean water tank 20.

[0212] The heater 55 is used to heat the purified water, and the water vapor separator 60 is used to separate the water vapor in the heated purified water. The water vapor separator 60 is provided with a water vapor separation outlet 61, which forms the water inlet of the water purifier 100.

[0213] 2 and 3 , when the user needs to take clean water, the water pump 50 works, and the water in the clean water tank 20 and the liquid level box 10 is synchronously drawn into the heater 55 through the communicating vessel 30 . After passing through the heater 55 , the water continues to pass through the water vapor separator 60 and is taken out from the water vapor separation outlet 61 .

[0214] When the water level in the liquid level box 10 is lower than the high liquid level described below, the filter 40 works to purify the water source to be purified, and the purified water enters the liquid level box 10 and the clean water tank 20 respectively through the communicating vessel 30.

[0215] The various parts of the water purifier 100 will be described in detail below with reference to the accompanying drawings.

[0216] 1 and 2 , the interior of the housing 80 is hollow and includes a rear panel 870, a top cover 871, a base 872, and a front panel 873. The rear panel 870, the top cover 871, the base 872, and the front panel 873 collectively enclose a housing cavity, within which the filter 40, the communicating vessel 30, the liquid level box 10, the water pump 50, and the heater 55 are disposed. The rear panel 870 and the front panel 873 are disposed on the sides of the base 872 to form the main body of the housing 80, and the top cover 871 covers the front panel 873 and the rear panel 870.

[0217] A supporting member 81 is further provided on the outer wall of the shell 80 , and the clean water tank 20 is detachably disposed on the supporting member 81 .

[0218] The supporting member 81 is constructed as a water collecting box 85 , which is detachably arranged outside the shell 80 , and the top wall of the water collecting box 85 is provided with a water collecting hole 82 connected to the inside, and the clean water tank 20 is supported on the top wall of the water collecting box 85 .

[0219] Like this, clean water tank 20 is detachably arranged on the outside of housing 80, makes the user when needing a large amount of water, can directly unload clean water tank 20 and take water.In addition, can conveniently remove clean water tank 20, carry out maintenance operation such as cleaning.

[0220] In addition, referring to Figures 1 and 2 , a portion of the structure of the water vapor separator 60 passes through the housing 80 and extends outside the housing 80. The water vapor separation outlet 61 is located on the portion of the water vapor separator 60 that extends outside the housing 80. This facilitates the user to draw water from the water vapor separation outlet 61 outside the housing 80. For example, a relief opening 8731 can be formed on the front panel 873, through which the water vapor separation outlet 61 extends to the outside of the housing 80.

[0221] In the embodiment of the present application, referring to FIG4 , the water level sensor 12 is configured as a float sensor and includes a first float 121 and a second float 122. The liquid level box 10 is provided with a first upper baffle 123, a first lower baffle 124, a second upper baffle 125, and a second lower baffle 126 in order along the height direction of the liquid level box 10. The first float 121 is located between the first upper baffle 123 and the first lower baffle 124, and the second float 122 is located between the second upper baffle 125 and the second lower baffle 126.

[0222] The water level sensor 12 is configured to detect the liquid level in the liquid level box 10 (also called the water level when the liquid level box contains water), and when the first float 121 abuts against the first upper baffle 123, it is determined that the liquid level is at a high level, and when the second float 122 abuts against the second lower baffle 126, it is determined that the liquid level is at a low level.

[0223] With this arrangement, the corresponding float stroke is relatively short regardless of whether it is detecting high or low liquid levels. Compared with the solution of setting only one float, it avoids the situation where the float has a long stroke at different liquid levels, which makes it easy for it to get stuck and cause inaccurate detection results or float failure.

[0224] In an embodiment of the present application, the water purifier 100 also includes a controller (not shown), which is electrically connected to the water level sensor 12 and the booster pump. The controller is configured to control the booster pump to stop working and thus stop water production when the liquid level in the liquid level box 10 is at a high liquid level; when the liquid level in the liquid level box 10 is lower than the high liquid level, control the booster pump to start working to produce water; when the liquid level in the liquid level box 10 is at a low liquid level, control the water pump 50 to stop working to stop water discharge.

[0225] In the embodiment of the present application, the water purifier 100 further includes an exhaust component 70 .

[0226] The exhaust member 70 is configured with a first chamber E communicating with the atmosphere. The first chamber E is communicated with a filter liquid outlet (not shown) of the filter 40 .

[0227] As previously described, the manifold 30 is configured with a manifold inner cavity C, which is in communication with the clean water tank 20, the liquid level box 10, and the first chamber E. For example, water filtered by the filter 40 can be sequentially input into the vent 70 and the manifold 30, and then flow into the liquid level box 10 and the clean water tank 20 through the manifold inner cavity C. Furthermore, the manifold 30 is also in communication with the filter outlet on the filter body 43, described later, and the water inlet of the water purifier.

[0228] By providing the exhaust component 70, the air in the communicating vessel 30 during the initial water production and the air entering the filter 40 can be discharged through the exhaust component 70. In other words, the water filtered out of the filter 40 is directly exhausted through the exhaust component 70, reducing the amount of gas entering the communicating vessel 30. This not only solves the problem of hot water jetting, but also solves the problem of unstable water shape and slow water outlet speed at the water inlet of the water purifier 100, and further facilitates the smooth flow of water.

[0229] Continuing with FIG3 , the liquid level box 10 is provided with an air outlet 13 communicating with the atmosphere; the exhaust member 70 is provided on the liquid level box 10, and the first chamber E is communicated with the liquid level box inner cavity A of the liquid level box 10 to communicate with the atmosphere through the air outlet 13. In this way, the liquid level box 10 and the exhaust member 70 can be integrally provided, which can reduce the number of parts and save installation steps.

[0230] Further, referring to Figure 5, the exhaust member 70 is provided on the outer side wall of the liquid level box 10. The exhaust member 70 and the side walls of the liquid level box 10 facing each other are provided with a communication port 14 that communicates with each other so that the first chamber E communicates with the liquid level box inner cavity A. The liquid level box 10 is communicated with the atmosphere through the first chamber E and the liquid level box inner cavity A, and thus the first chamber E of the exhaust member 70 communicates with the atmosphere through the liquid level box inner cavity A.

[0231] As for the communication mode between the various components, with reference to Figures 3, 4, and 5, for example, the exhaust member 70 may be provided with an exhaust member liquid inlet 72 and an exhaust member liquid outlet 73, the communicating vessel 30 may be provided with a communicating vessel liquid inlet 33 communicating with the communicating vessel inner cavity C, the exhaust member liquid inlet 72 is communicated with the filter liquid outlet via a first pipe 101, and the exhaust member liquid outlet 73 is communicated with the communicating vessel liquid inlet 33 of the communicating vessel 30 via a second pipe 102;

[0232] The heights of the vent 70 and the communication port 14 on the liquid level box 10 relative to the bottom wall of the liquid level box 10 are higher than the height of the vent liquid inlet 72. This prevents water that enters the vent 70 through the vent liquid inlet 72 from entering the liquid level box 10 through the communication port 14.

[0233] 3 , further, the communicating vessel liquid inlet 33 is connected to the filter liquid outlet of the filter 40 through the vent 70 , the communicating vessel liquid inlet 33 has a diameter greater than 6 mm, and the inner diameter of the second pipe 102 is greater than 6 mm.

[0234] When the diameter of the communicating vessel liquid inlet 33, or the inner diameter of the second pipe 102 connected to the communicating vessel liquid inlet 33 is less than 6 mm, the process of the air in the communicating vessel 30 entering the exhaust component 70 through the second pipe 102 is hindered, and poor exhaust is likely to occur, making it difficult for water to flow from the exhaust component 70 to the communicating vessel 30 stably and smoothly, resulting in the possibility that the accumulated water in the exhaust component 70 directly enters the liquid level box 10 from the communicating port 14, causing the water level in the liquid level box 10 to be too high, affecting the judgment of the water level in the clean water tank 20.

[0235] FIG6 is a schematic structural diagram of the filter 40 in the water purifier 100 provided in an embodiment of the present application.

[0236] 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 having one end open (connected to the atmosphere). The filter body 43 is disposed in the filter cavity 44 . The air outlet 13 provided on the liquid level box 10 is connected to the interior of the filter shell 42 of the filter 40 .

[0237] The inside of the filter housing 42, that is, the filter inner cavity 44 is connected to the atmosphere, and the air outlet 13 is connected to the inside of the filter housing 42 of the filter 40, so that the liquid level box 10 is connected to the atmosphere. In addition, the clean water tank 20 is also connected to the atmosphere. Therefore, when the water purifier 100 takes water to the liquid level box 10 and the clean water tank 20 through the communicating vessel 30, or the water filtered by the filter 40 enters the liquid level box 10 and the clean water tank 20 through the communicating vessel 30, according to the communicating vessel principle, the water level in the liquid level box 10 and the water level in the clean water tank 20 can be kept roughly equal, so that the water level in the liquid level box 10 can more accurately reflect the water level in the clean water tank 20.

[0238] The liquid level box 10 (the air outlet 13 ) is in communication with the interior of the filter 40 (ie, the filter inner cavity 44 inside the filter housing 42 ) through the third pipe 103 .

[0239] Furthermore, the liquid level box 10 includes a box body 15 and a box cover 16 with a sealing cover disposed on the box body 15 , and the air outlet 13 is provided on the box cover 16 .

[0240] In specific implementation, as mentioned above, the filter housing 42 is provided with a filter housing air inlet 41 connected to the filter inner cavity, and both ends of the third pipe 103 are respectively connected to the air outlet 13 and the filter housing air inlet 41 to connect the liquid level box 10 with the atmosphere.

[0241] It can be understood that in order to access the filter body 43, the filter cavity must be provided with an opening, and the filter cavity is also connected to the atmosphere. By connecting the air outlet 13 of the liquid level box 10 with the filter cavity of the filter 40 through the third pipe 103, without adding a new opening on the shell 80 of the water purifier 100, the overall appearance of the water purifier 100 is more beautiful.

[0242] For example, a filter extension tube 421 is provided on the filter housing 42, communicating with the interior of the filter housing 42 through the filter housing air inlet 41. A liquid level box extension tube 161 is provided on the box cover 16 at a position corresponding to the air outlet 13. The ends of the third pipe 103 are respectively connected to the filter extension tube 421 and the liquid level box extension tube 161. This arrangement facilitates the connection of the ends of the third pipe 103 to the filter housing 42 and the liquid level box 10.

[0243] Furthermore, a first mounting portion 162 is provided on the box body 15, and a second mounting portion 422 is provided on the filter housing 42. The first mounting portion 162 is connected to the second mounting portion 422 to connect the liquid level box 10 to the filter 40. It is understandable that the number of the first mounting portion 162 and the second mounting portion 422 may also be multiple. For example, a portion of the first mounting portion 162 may also be provided on the box body 15, and the second mounting portion 422 corresponding to the portion of the first mounting portion 162 is provided at a position on the filter housing corresponding to the first mounting portion 162.

[0244] In addition, as mentioned above, the water pump 50 is connected to the communicating vessel 30 and the heater 55 respectively, and is used to pump water in the liquid level box 10 and the clean water tank 20 to the heater 55 through the communicating vessel 30 .

[0245] The steam separator 60 includes a steam separation outlet 62 and the aforementioned steam separation water outlet 61. The steam separation outlet 62 is communicated with the interior of the filter housing 42. In this way, the steam discharged from the steam separation outlet 62 can be discharged into the atmosphere through the filter housing 42.

[0246] In the embodiment of the present application, the filter 40 includes three stages of filtration to achieve a better filtering effect.

[0247] In specific implementation, the filter body 43 includes a first-stage filter 431, a second-stage filter 432, and a third-stage filter 433 connected in sequence, and the filter cavity 44 includes a first-stage filter cavity 441, a second-stage filter cavity 442, and a third-stage filter cavity 443 that are connected. The first-stage filter 431 is accommodated in the first-stage filter cavity 441, the second-stage filter 432 is accommodated in the second-stage filter cavity 442, and the third-stage filter 433 is accommodated in the third-stage filter cavity 443. The air outlet 13 is connected to the first-stage filter cavity 441.

[0248] By configuring the filter body 43 to include a primary filter 431 , a secondary filter 432 , and a tertiary filter 433 that are connected in sequence, a better filtering effect can be achieved.

[0249] Furthermore, the water purifier 100 includes a booster pump for pumping water to be purified into the filter body 43, where the water is purified. By providing a booster pump as a power source for the purifier's water production, it can be used with a variety of water sources, such as water tanks, in addition to water sources with a certain water pressure, such as tap water pipes.

[0250] In the embodiment of the present application, in combination with Figures 3 and 4, as described above, the water pump 50 is respectively connected to the communicating vessel 30 and the heater 55, and is used to pump the water in the liquid level box 10 and the clean water tank 20 to the heater 55 through the communicating vessel 30. The water vapor separator 60 is connected to the heater 55 and is used to separate the water vapor of the water heated by the heater 55.

[0251] With this arrangement, when a user draws water, the water pump 50 draws water from the communicating vessel 30 , and the water in the liquid level box 10 and the clean water tank 20 flows into the water pump 50 at the same time. The water in the water pump 50 flows into the heater 55 , and after passing through the heater 55 , flows into the water vapor separator 60 and flows out of the water vapor separator 60 .

[0252] 6 , the steam separation outlet 62 is further connected to the third pipe 103 via the fourth pipe 104. Thus, the steam separated by the steam separation outlet 62 can also be discharged into the atmosphere through the filter housing 42. This can also reduce the number of pipes, making the structure more compact.

[0253] As for the connection between the clean water tank 20 and the atmosphere, as shown in FIG4 , the clean water tank 20 includes a clean water tank body 25 and a water tank cover 26 that is openably and closably mounted on the clean water tank body 25. A gap is provided between the clean water tank body 25 and the water tank cover 26 to allow the clean water tank 20 to communicate with the atmosphere. In this way, when a user needs a large amount of water, he or she can open the water tank cover 26 and pour it out to use.

[0254] Furthermore, the water vapor separation outlet 62 is provided at the top end of the water vapor separator 60 , and the third pipe 103 and the fourth pipe 104 are located on one side of the top end of the liquid level box 10 and the water vapor separator 60 .

[0255] In this way, the lengths of the third pipe 103 and the fourth pipe 104 can be set shorter, and combined with the upward trend of water vapor, the water vapor can be discharged more smoothly.

[0256] FIG7 is a schematic cross-sectional view of the water purifier 100 provided in an embodiment of the present application.

[0257] In the embodiment of the present application, as previously described, the manifold 30 is connected to the liquid level box 10 and the clean water tank 20, respectively. Specifically, referring to Figures 3 and 7 , the liquid level box 10 is provided with a liquid level box communication port 11, and the clean water tank 20 is provided with a clean water tank communication port 21. The manifold 30 also has a second communication port 31 and a first communication port 32; the second communication port 31 is connected to the liquid level box communication port 11, and the first communication port 32 is connected to the clean water tank communication port 21. This ensures that the manifold 30 is connected to the liquid level box 10 and the clean water tank 20, respectively.

[0258] 3 and 4 , the communicating vessel 30 is further provided with a communicating vessel liquid outlet 38 , which is connected to the water inlet of the water purifier 100 ; the setting height of the liquid level box communicating port 11 relative to the bottom of the water purifier 100 is higher than the setting height of the communicating vessel liquid outlet 38 .

[0259] With such an arrangement, the liquid in the liquid level box 10 can flow out of the communicating vessel 30 more smoothly through the communicating vessel liquid outlet 38, thereby avoiding the situation where the liquid level box 10 does not discharge liquid smoothly and water accumulates in the liquid level box 10, resulting in the clean water provided to the water intake being water mixed with the accumulated water.

[0260] In a specific implementation, the manifold 30 is provided with an extension tube 39 that extends from the outside (e.g., the top) of the manifold 30 through the wall of the manifold 30 to the bottom of the manifold cavity C. The end of the extension tube 39 located within the manifold cavity C forms a manifold liquid outlet 38.

[0261] Of course, the connection between the water pump 50 and the manifold 30 is achieved by connecting the manifold outlet 38 to the inlet of the water pump 50 through a pipe. The outlet of the water pump 50 is also connected to the heater 55 through another pipe to transport the clean water in the manifold 30 to the heater 55. The water pump 50 can be connected to the outer wall of the exhaust member 70 by fasteners such as screws.

[0262] Furthermore, the height of the manifold inlet 33 relative to the bottom of the water purifier 100 is higher than the heights of the liquid level box communication port 11, the clean water tank communication port 21, and the manifold outlet 38. The manifold inlet 33 can be located at the very top of the manifold 30. This allows the purified water entering the manifold 30 through the manifold inlet 33 to flow smoothly into the liquid level box 10 and the clean water tank 20.

[0263] FIG8 is a schematic diagram of another structure of the communicating vessel 30 in the water purifier 100 provided in an embodiment of the present application.

[0264] 8 , since both water production and water intake of the water purifier 100 pass through the manifold 30, during the water production process, air cannot be discharged smoothly due to the small volume of the manifold 30. Therefore, it is possible to connect the manifold cavity C to the filter outlet of the filter 40. For example, the filter outlet of the filter 40 can be connected to the manifold inlet 33 through a pipe (not shown). In this case, the manifold inlet 33 can be connected to the exhaust member 70 at the same time, or only to the filter outlet without being connected to the exhaust member 70.

[0265] Furthermore, a vent 701 is provided on the manifold 30 to connect to the atmosphere. The vent 701 communicates with the manifold's inner cavity C, facilitating the smooth evacuation of air from the manifold 30 during water production and dispensing by the water purifier 100. This ensures smooth water flow and maintains a real-time equilibrium between the water levels in the clean water tank 20 and the float box. When the manifold's liquid inlet 33 is connected only to the filter's liquid outlet and not to the vent 70, water filtered by the filter 40 enters the manifold's inner cavity C directly from the manifold's liquid inlet 33, bypassing the vent 70, and is exhausted by the vent 701.

[0266] In a specific implementation, the top of the manifold 30 is provided with an exhaust port 301 connected to the manifold inner cavity C, and the exhaust port 301 forms an exhaust portion 701. Of course, in order to facilitate the smooth discharge of air in the manifold 30, the exhaust port 301 is further provided with an exhaust pipe 302, which extends along the height direction of the water purifier 100.

[0267] It should be noted that, in another possible embodiment, the liquid inlet 33 of the communicating vessel can be simultaneously connected to the liquid outlet of the filter of the exhaust component 70. The water in the filter 40 can partially enter the communicating vessel 30 through the exhaust component 70, or can partially enter the communicating vessel 30 directly through the pipe connected to the liquid inlet 33 of the communicating vessel. At this time, exhaust can be carried out simultaneously through both the exhaust component 70 and the exhaust part 701.

[0268] The working process of the water purifier 100 according to the embodiment of the present application will be described below with reference to FIG3 and FIG7 .

[0269] When the user needs to take clean water, as shown by the dotted arrow in Figure 3, the water pump 50 works, and the clean water in the clean water tank 20 enters the inner cavity C of the communicating vessel through the clean water tank connecting port 21 and the first connecting port 32. The clean water in the liquid level box 10 enters the inner cavity C of the communicating vessel through the liquid level box connecting port 11 and the second connecting port 31. Driven by the water pump 50, the clean water in the inner cavity C of the communicating vessel enters the water pump 50 through the liquid outlet 38 of the communicating vessel and enters the heater 55 connected to the water pump 50. When the clean water enters the heater 55, the heater 55 works to heat the clean water. If the heater 55 does not work, the clean water will not be heated. The water entering the heater 55 eventually enters the water vapor separator 60. After the heated clean water is separated from the water vapor by the water vapor separator 60, the clean water flows out from the water vapor separation outlet 61. If the clean water is not heated in the heater 55, it also flows out directly through the water vapor separation outlet 61. In this process, the water pump 50 serves as a driving source for the entire cycle.

[0270] During the water production process, as indicated by the solid arrows in Figures 3 and 4 , the booster pump (not shown) operates, the filter 40 purifies the water source to be purified, and the purified water is transported through the first pipe 101 to the first chamber E of the exhaust member 70. The purified water then enters the inner cavity C of the manifold through the exhaust member liquid outlet 73, the second pipe 102, and the manifold liquid inlet 33. A portion of the purified water entering the inner cavity C of the manifold enters the clean water tank 20 through the first connecting port 32 and the clean water tank connecting port 21, while the remaining portion enters the liquid level box 10 through the second connecting port 31 and the liquid level box connecting port 11. Specifically, during the water production process, when the water level in the liquid level box 10 falls below the high liquid level, the filter 40 operates to purify the water source to be purified. The purified water then enters the liquid level box 10 and the clean water tank 20, respectively, through the aforementioned process. During this process, the booster pump serves as the driving source for the entire cycle.

[0271] 3 and 7 , the volume of the clean water tank cavity B of the clean water tank 20 is greater than the volume of the liquid level box cavity A of the liquid level box 10. As previously mentioned, the water filtered by the filter 40 can flow into the liquid level box 10 and the clean water tank 20 through the inner cavity C of the communicating vessel.

[0272] 4 and FIG. 9 described later, the minimum cross-sectional area of ​​the first connecting channel P connecting the clean water tank connecting port 21 with the inner cavity C of the communicating vessel is greater than the minimum cross-sectional area of ​​the second connecting channel Q connecting the liquid level box connecting port 11 with the inner cavity C of the communicating vessel.

[0273] Since the volume of the clean water tank cavity B of the clean water tank 20 is larger than the volume of the liquid level box cavity A of the liquid level box 10, if the water inlet and outlet speeds of the clean water tank 20 are the same as those of the liquid level box 10, it is easy for the liquid level in the clean water tank 20 to temporarily be higher than that of the liquid level box 10 when the water purifier 100 is in use. In the present application, by making the minimum cross-sectional area of ​​the first channel P larger than the minimum cross-sectional area of ​​the second channel Q, the water inlet and outlet volume per unit time of the clean water tank 20 is greater than that of the liquid level box 10. That is, the water outlet speed of the larger clean water tank 20 is greater than that of the smaller liquid level box 10. This can compensate for the temporary liquid level difference caused by the volume difference between the two. When the water purifier 100 is in use, the liquid levels of the clean water tank 20 and the liquid level box 10 remain consistent in real time, so that the water level detected by the water level detector in the liquid level box 10 can always truly reflect the water level in the clean water tank 20, avoiding the occurrence of reverse water leakage.

[0274] Furthermore, the communicating vessel 30 is provided with a communicating vessel connecting pipe 34 communicating with the communicating vessel inner cavity C. The communicating vessel connecting pipe 34 is provided at a position corresponding to that of the first communicating port 32 .

[0275] The clean water tank 20 is provided with a clean water tank connecting pipe 22, which corresponds to the setting position of the clean water tank connecting port 21, and is connected to the clean water tank inner cavity B of the clean water tank 20; the clean water tank connecting pipe 22 is configured to be partially inserted into the communicating vessel connecting pipe 34 when carried on the supporting member 81 so that the communicating vessel inner cavity C and the clean water tank inner cavity B are connected.

[0276] The portion of the pipe in the communicating vessel connecting pipe 34 that is not connected to the clean water tank connecting pipe 22 and the clean water tank connecting pipe 22 together define a first communicating channel P. The smallest cross-sectional area of ​​the first communicating channel P is located on the portion of the pipe in the communicating vessel connecting pipe 34 that is not connected to the clean water tank connecting pipe 22.

[0277] Furthermore, the communicating vessel 30 is provided with a communicating vessel plug-in pipe 341 communicating with the communicating vessel inner cavity C, and the communicating vessel plug-in pipe 341 is provided at a position corresponding to the second communicating port 31 .

[0278] The liquid level box 10 is provided with a liquid level box plug-in tube 17 , which is in communication with the inner cavity A of the liquid level box; the liquid level box plug-in tube 17 is plugged into the communicating vessel plug-in tube 341 .

[0279] The portion of the communicating tube 341 not connected to the liquid level box tube 17 and the liquid level box tube 17 together define a second communicating channel Q. The smallest cross-sectional area of ​​the second communicating channel Q is located inside the liquid level box tube 17.

[0280] In the embodiment of the present application, the cross-sectional area S1 of the inner cavity B of the water purification tank along the height direction of the water purifier 100, the minimum cross-sectional area S2 of the first connecting channel P, the cross-sectional area S3 of the inner cavity A of the liquid level box along the height direction of the water purifier 100, and the minimum cross-sectional area S4 of the second connecting channel Q satisfy: S3 / S4=K*S1 / S2

[0281] Wherein, K is the resistance coefficient of the fluid in the liquid level box communication port 11 , and the cross-section of the inner cavity B of the water purification tank and the cross-section of the inner cavity A of the liquid level box remain unchanged along the height direction of the water purifier 100 .

[0282] In addition, the value of the fluid resistance coefficient K will change with the depth or shape of the hole at the communication port 11 of the liquid level box.

[0283] In this way, when the water purifier 100 is in use, the liquid levels in the clean water tank 20 and the liquid level box 10 can always remain completely consistent, so that the water level detected by the water level detector in the liquid level box 10 can reflect the actual water level in the clean water tank 20 in real time, avoiding the occurrence of reverse water duplication.

[0284] Furthermore, the cross-sectional area S1 of the inner cavity B of the water purification tank along the height direction of the water purifier 100 and the cross-sectional area S3 of the inner cavity A of the liquid level box along the height direction of the water purifier 100 satisfy: S1>S3;

[0285] The bottom wall of the inner cavity B of the clean water tank is flush with the bottom wall of the inner cavity A of the liquid level box.

[0286] In this way, the water level detected by the water level detector in the liquid level box 10 can be made the true water level in the clean water tank 20 .

[0287] Furthermore, the cross-sectional area of ​​the first communication port 32 is larger than the cross-sectional area of ​​the second communication port 31 .

[0288] Furthermore, the cross-sectional area of ​​the liquid level box communication port 11 is greater than or equal to 4.5 mm 2 And / or the cross-sectional area of ​​the clean water tank communication port 21 is greater than 40mm 2 .

[0289] If the cross-sectional area of ​​the liquid level box communication port 11 is too large, that is, the diameter of the liquid level box communication port 11 is too large, the water flow rate in the liquid level box 10 is relatively fast, causing the water level in the liquid level box 10 to drop too quickly, resulting in the liquid in the liquid level box 10 dropping too quickly and the liquid level being lower than the clean water tank 20. As a result, the water level detected by the water level detector cannot reflect the actual water level in the clean water tank 20. When the cross-sectional area of ​​the liquid level box communication port 11 is too small, that is, the diameter of the liquid level box communication port 11 is too small, the water flow rate in the liquid level box 10 is relatively slow, causing the water level in the liquid level box 10 to drop too slowly. Similarly, the water level detected by the water level detector cannot reflect the actual water level in the clean water tank 20.

[0290] When the cross-sectional area of ​​the liquid level box communication port 11 is greater than or equal to 4.5 mm 2 , and / or the cross-sectional area of ​​the clean water tank communication port 21 is greater than 40mm 2 At this time, it can be ensured that the water in the liquid level box 10 enters and exits the communicating vessel 30 through the liquid level box connecting port 11, and when the water in the clean water tank 20 enters and exits the communicating vessel 30 through the clean water tank connecting port 21, the rise and fall of the water level in the liquid level box 10 and the rise and fall of the water level in the clean water tank 20 are carried out synchronously, so that the water level detection result in the liquid level box 10 detected by the water level detector can more accurately reflect the water level in the clean water tank 20.

[0291] FIG9 is a schematic diagram showing the result of the cooperation between the first communication port 32 and the clean water tank communication port 21 in the water purifier 100 provided in an embodiment of the present application.

[0292] In the embodiment of the present application, as mentioned above, a supporting member 81 is further provided on the outer wall of the shell 80 , and the clean water tank 20 is detachably disposed on the supporting member 81 .

[0293] 3 , 8 and 9 , in order to connect the clean water tank 20 with the communicating vessel 30 , the first communicating port 32 and the clean water tank communicating port 21 are respectively provided with a communicating vessel check valve 36 and a clean water tank check valve 27 .

[0294] Furthermore, as mentioned above, the communicating vessel 30 is provided with a communicating vessel connecting pipe 34 connected to the communicating vessel inner cavity C, and the communicating vessel connecting pipe 34 is arranged at a position corresponding to the first connecting port 32. In specific implementation, at least part of the structure of the communicating vessel 30 is arranged in the shell 80, and the communicating vessel connecting pipe 34 passes through the shell 80 to the outside of the shell 80 and extends to the load-bearing side of the support member 81.

[0295] In this way, most of the communicating vessel 30 is accommodated in the shell 80, and only the communicating vessel connecting pipe 34 for connecting to the water purifier 100 is extended out of the shell 80. The clean water tank 20 can be placed on the supporting member 81 outside the shell 80 for easy access by the user.

[0296] Correspondingly, the clean water tank 20 is provided with a clean water tank connecting pipe 22, which is in communication with the clean water tank inner cavity B of the clean water tank 20 and is arranged at a position corresponding to the clean water tank communication port 21. The manifold check valve 36 is located in the manifold connecting pipe 34, and the clean water tank check valve 27 is arranged in the clean water tank connecting pipe 22.

[0297] The clean water tank connecting pipe 22 is configured to be able to be inserted into the communicating vessel connecting pipe 34 when it is carried on the supporting member 81 to connect the communicating vessel inner cavity C and the clean water tank inner cavity B. For example, when the clean water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the clean water tank check valve 27 pushes open the valve core 361 of the communicating vessel check valve to realize the water inlet and outlet of the communicating vessel 30 and the clean water tank 20.

[0298] More specifically, referring to Figures 3 and 8 , a valve seat 362 is provided in the communicating vessel connecting pipe 34. The valve core 361 of the communicating vessel check valve is elastically connected to the valve seat 362, for example, by an elastic member. When the clean water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the valve core 271 of the clean water tank check valve overcomes the elastic force of the elastic member and presses against the valve core 361 of the communicating vessel check valve to open the communicating vessel check valve 36. At the same time, the valve core 361 of the communicating vessel check valve also pushes open the valve core 271 of the clean water tank check valve to open the clean water tank check valve 27. When the clean water tank connecting pipe 22 is separated from the communicating vessel connecting pipe 34, the valve core 361 of the communicating vessel check valve returns to its original state under the action of the elastic member (not shown), closing the communicating vessel connecting pipe 34. Of course, when the clean water tank connecting pipe 22 is separated from the communicating vessel connecting pipe 34, the valve core 271 of the clean water tank check valve also returns to its original state under the action of the elastic member, closing the clean water tank connecting pipe 22.

[0299] Exemplarily, the cross-sectional area of ​​the valve core 361 of the communicating vessel check valve is less than or equal to the cross-sectional area of ​​the valve core 271 of the clean water tank check valve.

[0300] In this way, when the clean water tank connecting pipe 22 is inserted into the communicating vessel connecting pipe 34, the valve core 271 of the clean water tank check valve can reliably press against the valve core 361 of the communicating vessel check valve to smoothly open the communicating vessel check valve 36, thereby realizing the water inflow and outflow from the communicating vessel 30 to the clean water tank 20.

[0301] Figure 10 is a schematic cross-sectional view of the structure in which the first communication port 32 and the clean water tank communication port 21 are separated in the water purifier 100 provided in an embodiment of the present application; Figure 11 is a partial enlarged view of the U portion of Figure 10; Figure 12 is a schematic cross-sectional view of the structure in which the first communication port 32 and the clean water tank communication port 21 are matched in the water purifier 100 provided in an embodiment of the present application; Figure 13 is a partial enlarged view of the V portion of Figure 12. Figure 14 is a schematic view of the structure in which the sealing ring 35 and the communicating vessel connecting pipe 34 are matched in the water purifier 100 provided in an embodiment of the present application. It should be noted that in Figures 12 and 13, the structure of the clean water tank check valve 27 is omitted for ease of observation.

[0302] In the embodiment of the present application, referring to Figures 9, 10, 11, 12 and 13, a sealing ring 35 is provided on the inner wall of the communicating vessel connecting pipe 34, and the axial ends of the sealing ring 35 abut against the inner wall of the communicating vessel connecting pipe 34. The first sealing section 353 between the axial ends of the sealing ring 35 and the inner wall of the communicating vessel connecting pipe 34 jointly define a water storage chamber F; the clean water tank connecting pipe 22 is configured to be inserted into the communicating vessel connecting pipe 34 when it is carried on the supporting member 81 so that the communicating vessel inner cavity C and the clean water tank inner cavity B are connected; and the first sealing section 353 is elastically deformed toward its own radial outside to squeeze the water in the water storage chamber F into the communicating vessel connecting pipe 34; and when it is separated from the communicating vessel connecting pipe 34, the first sealing section 353 is elastically reset toward its own radial inside to absorb the water in the communicating vessel connecting pipe 34 into the water storage chamber F.

[0303] In the above embodiment, the first sealing section 353 between the axial ends of the sealing ring 35 and the inner wall of the manifold connecting pipe 34 jointly define a water storage chamber F. This water storage chamber F has a certain water storage capacity. Because the clean water tank connecting pipe 22 can elastically return radially inward when it is separated from the manifold connecting pipe 34, the first sealing section 353 is attracted to the water storage chamber F. Therefore, when the clean water tank 20 is removed by the user and the clean water tank connecting pipe 22 is separated from the manifold connecting pipe 34, even if there is water in the manifold 30 that flows into the manifold connecting pipe 34, it will be partially or completely absorbed by the water storage chamber F, thereby alleviating the problem of some water flowing into the manifold connecting pipe 34 due to the momentary separation of the clean water tank connecting pipe 22 and the manifold connecting pipe 34 when the clean water tank 20 is removed.

[0304] 11 and 13 , further, of the two axial ends of the sealing ring 35 , the end facing the clean water tank 20 is defined as a first end 351 , and the end away from the clean water tank 20 is defined as a second end 352 ;

[0305] 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 of the communicating vessel connecting pipe 34 facing the clean water tank 20 is snapped into the flange portion mounting groove G so that part of the structure of the first end portion 351 abuts against the inner wall of the communicating vessel connecting pipe 34.

[0306] In this way, the first end 351 of the sealing ring 35 covers the end of the communicating tube 34 facing the clean water tank 20, thereby preventing the water in the water storage chamber F from leaking from the first end 351, that is, the side facing the clean water tank 20.

[0307] Furthermore, the second end portion 352 is provided with an annular protrusion 3521, which abuts against the inner wall of the communicating tube 34. The protrusion 3521, the outer peripheral surface of the first sealing section 353 and the flange portion 3511 jointly define a water storage groove, and the water storage groove and the inner wall of the communicating tube 34 jointly define a water storage chamber F.

[0308] Thus, by providing a water-retaining groove on the sealing ring 35 to form the water-retaining chamber F, the structure is relatively simple and easy to manufacture. Furthermore, the clean water tank connecting pipe 22 is easily inserted into the inner side of the sealing ring 35, pressing the inner circumference of the sealing ring 35 radially outward, causing the first sealing section 353 to elastically deform radially outward, thereby squeezing the water in the water-retaining chamber F into the communicating vessel connecting pipe 34.

[0309] In the embodiment of the present application, referring to Figure 11 , the inner circumferential surface of the first sealing section 353 is protrudingly provided with at least two annular interference fit portions 3531 , at least two interference fit portions 3531 are arranged at axial intervals along the sealing ring 35 , and at least two interference fit portions 3531 are used for interference fit with the clean water tank connecting pipe 22 .

[0310] In this way, when the clean water tank connecting pipe 22 is inserted into the inside of the manifold connecting pipe 34 , it can be sealed with the sealing ring 35 to prevent water from leaking between the clean water tank connecting pipe 22 and the manifold connecting pipe 34 .

[0311] Illustratively, along the direction from the first end 351 to the second end 352 , the protruding height of the interference fit portion 3531 from the inner circumferential surface of the sealing ring 35 gradually decreases.

[0312] As the water tank connecting tube 22 is inserted into the communicating vessel connecting tube 34 from the first end 351 toward the second end 352, the water tank connecting tube 22 first contacts the interference fit portion 3531, which has a higher protrusion height. This quickly seals the water and prevents leakage. As the insertion continues, the water tank connecting tube 22 engages the interference fit portion 3531, which has a lower protrusion height. The interference fit is relatively small, which reduces the difficulty of inserting the water tank connecting tube 22 and improves the insertion feel.

[0313] In the embodiment of the present application, referring to FIG. 14 , there are two interference fit portions 3531 , and a support protrusion 354 is provided on the outer circumferential surface of the sealing ring 35 between the areas corresponding to the two interference fit portions 3531 .

[0314] In this way, when the clean water tank connecting pipe 22 is inserted into the inner side of the sealing ring 35, the interference fit portion 3531 elastically deforms toward the inner wall of the communicating vessel connecting pipe 34 under the pressure of the clean water tank connecting pipe 22, and the support protrusion 354 first contacts the inner wall of the communicating vessel connecting pipe 34. At this time, on the outer peripheral surface of the sealing ring 35, the areas corresponding to the two interference fit portions 3531 will form two avoidance spaces with the inner wall of the communicating vessel connecting pipe 34. The existence of the two avoidance spaces allows the two interference fit portions 3531 to still have room for elastic deformation radially outward or radially inward, thereby preventing the clean water tank connecting pipe 22 from being incompatible with the sealing ring 35 due to dimensional tolerance, etc., and can also solve the problem of poor hand feel during the insertion process of the clean water tank connecting pipe 22.

[0315] Furthermore, there are two interference fit parts 3531, and on the outer peripheral surface of the sealing ring 35, the areas corresponding to the two interference fit parts 3531 are respectively provided with avoidance grooves H; the groove depth of the avoidance groove H corresponding to the interference fit part 3531 with a higher protruding height is greater than the groove depth of the avoidance groove H corresponding to the interference fit part 3531 with a lower protruding height.

[0316] In this way, the interference fit portion 3531 with a higher protruding height has a larger avoidance space, and the interference fit portion 3531 with a lower protruding height has a smaller avoidance space. Such a differentiated design makes the capacity of the water storage chamber F as large as possible.

[0317] 3 , 9 , and 13 , when the clean water tank connecting pipe 22 of the clean water tank 20 is inserted into the manifold connecting pipe 34, the valve core 271 of the clean water tank check valve presses against the valve core 361 of the manifold check valve, opening the manifold check valve 36 and establishing communication between the clean water tank cavity B of the clean water tank 20 and the manifold cavity C of the manifold 30. At this point, the clean water tank connecting pipe 22 is inserted into the inner side of the sealing ring 35 and pushes the first sealing section 353 radially outward of the sealing ring 35, causing the outer wall of the first sealing section 353 to press against the inner wall of the manifold connecting pipe 34, thereby flattening the water storage cavity F. When the clean water tank connecting pipe 22 is drawn out from the communicating vessel connecting pipe 34, some water flows out from the valve core 361 of the communicating vessel check valve. At this time, the squeezing of the first sealing section 353 by the communicating vessel connecting pipe 34 disappears, the sealing ring 35 is restored, and the water storage chamber F returns to its original state. The water that has flowed out into the communicating vessel connecting pipe 34 will be squeezed into the water storage chamber F due to the action of atmospheric pressure and temporarily stored in the water storage chamber F.

[0318] FIG15 is a schematic structural diagram of the connection between the carrier 81 and the shell 80 in the water purifier 100 provided in an embodiment of the present application.

[0319] In an embodiment of the present application, referring to Figure 15, as described above, the supporting member 81 is detachably connected to the shell 80, for example, connected to the front panel 873, the supporting member 81 is constructed with a water collecting chamber D, and the top wall of the supporting member 81 is provided with a water collecting hole 82 connected to the water collecting chamber D, and the clean water tank 20 is supported on the top wall of the supporting member 81.

[0320] In this way, water leaking from the connection between the clean water tank 20 and the communicating vessel 30 can flow into the water collection chamber D through the water collection hole 82. Alternatively, the user can place a water cup on the carrier 81, and water outside the water cup and the clean water tank 20 can also flow into the water collection chamber D through the water collection hole 82.

[0321] Furthermore, a water guide portion 83 is provided on the outer wall of the shell 80 , and the supporting member 81 is detachably connected to the shell 80 by plugging and fitting with the water guide portion 83 .

[0322] The water guide portion 83 has a guide surface 831 . A guide hole 832 communicating with the water collecting chamber D is defined on the guide surface 831 . The guide surface 831 is configured to guide water in the communicating vessel connecting pipe 34 to the guide hole 832 .

[0323] 15 , the water in the communicating vessel connecting pipe 34 can be guided to the guide hole 832 by the guide portion and finally flow into the water collecting chamber D. The user can remove the carrier 81 regularly and clean the water in the water collecting chamber D.

[0324] Furthermore, to better guide water flowing out of the manifold connecting pipe 34, the projection of the end of the manifold connecting pipe 34 facing the clean water tank 20 on a first plane is within the projection of the guide surface 831 on the first plane, where the first plane is perpendicular to the height direction of the water purifier 100. This allows water to leak from the end of the manifold connecting pipe 34 and fall under gravity, which in turn allows it to be completely caught by the guide surface 831 and collected in the water collection chamber D. In a specific implementation, the guide surface 831 is constructed as a conical surface centered on the guide hole 832. This inclined conical surface provides better water guidance.

[0325] Furthermore, the shell 80 is provided with a through hole 8733 for the communicating vessel connecting pipe 34 to pass through; the communicating vessel 30 also includes a pressure cap 37, which is connected to the edge of the hole 8733, and the pressure cap 37 is provided with a pressure cap opening 371 for the clean water tank connecting pipe 22 to be inserted into the communicating vessel connecting pipe 34, and the pressure cap 37 presses the end of the sealing ring 35 facing the clean water tank 20 onto the communicating vessel connecting pipe 34.

[0326] In this way, the sealing ring 35 can be fixed more reliably on the communicating vessel connecting pipe 34. For example, the end of the pressure cover 37 is provided with a bent portion bent inwardly, and the top end of the bent portion is pressed tightly on the sealing ring 35.

[0327] Correspondingly, referring to Figure 10 , the outer wall of the clean water tank 20 is constructed with a clean water tank installation groove 28. The clean water tank connecting pipe 22 is disposed on the bottom wall of the clean water tank installation groove 28. An accommodating space I is defined between the outer wall of the clean water tank connecting pipe 22 and the side wall of the clean water tank installation groove 28. The accommodating space I is used to accommodate the gland 37. This makes the surface of the clean water tank 20 relatively flat and the structure more beautiful.

[0328] In the embodiment of the present application, in combination with Figures 2 and 15, in order to detect whether the clean water tank 20 is located on the carrier 81, the water purifier 100 also includes a sensor assembly 86, which is disposed in the shell 80 and is configured to detect the relative position of the clean water tank 20 and the carrier 81.

[0329] Regarding the placement of the sensor assembly 86, for example, it can be located inside the housing 80, such that the detection end of the sensor assembly 86 extends from inside the housing 80 to outside the housing 80 and extends to the support side of the carrier 81. Of course, to trigger the sensor assembly 86, a trigger portion 861 is provided on the outer wall of the clean water tank 20 at a position corresponding to the detection end. The trigger portion 861 is configured to contact the detection end when the clean water tank 20 is supported on the carrier 81, triggering the sensor assembly 86 to perform a detection. This facilitates determining whether the clean water tank 20 is positioned on the carrier 81.

[0330] In a specific implementation, the sensor assembly 86 can be, for example, a micro switch. When the clean water tank 20 is placed on the carrier 81, the trigger part 861 triggers the detection end of the sensor assembly 86 to detect that the clean water tank 20 is in place.

[0331] Figure 16 is a cross-sectional view of the water purification tank 20 in the water purifier 100 provided in an embodiment of the present application, Figure 17 is a cross-sectional view of the water purification tank 20 in the water purifier 100 provided in an embodiment of the present application from another angle, Figure 18 is a partial enlarged view at X in Figure 17, and Figure 19 is a schematic diagram of the decomposed structure of the sterilization unit 90 in the water purifier 100 provided in an embodiment of the present application.

[0332] 16, 17, 18, and 19, in the embodiment of the present application, the water purifier 100 further includes a sterilization unit 90 for sterilizing and disinfecting the purified water retained in the purified water tank 20. Specifically, referring to FIG10 and FIG17, the purified water tank 20 further includes a first mounting groove 29, and a first mounting opening 291 is provided on the bottom wall of the first mounting groove 29.

[0333] 18 and 19 , the sterilization unit 90 includes a lampshade 91, a lampshade positioning assembly 92, and a germicidal lamp 96. The lampshade positioning assembly 92 includes an annular first positioning member 93, a first sealing ring 94, and a second sealing ring 95. The lampshade 91 is located in the first mounting groove 29, and the head of the lampshade 91 is exposed to the clean water tank 20 through the first mounting opening 291. The first positioning member 93 is sleeved on the outer periphery of the lampshade 91. The first sealing ring 94 is sealingly disposed between the first positioning member 93 and the side groove wall of the first mounting groove 29. The second sealing ring 95 is sealingly disposed between the first positioning member 93 and the outer periphery of the lampshade 91. In a specific implementation, for example, the first sealing ring 94 is interference-fitted between the first positioning member 93 and the side groove wall of the first mounting groove 29, and the second sealing ring 95 is interference-fitted between the first positioning member 93 and the outer periphery of the lampshade 91.

[0334] The germicidal lamp 96 is disposed on the outer wall of the housing 80 . When the clean water tank 20 is supported on the supporting member 81 , the germicidal lamp 96 can extend into the inner side of the lampshade 91 .

[0335] In the above solution, the clean water tank 20 is detachably mounted on the support 81 on the outer wall of the housing 80, and the user can take the clean water tank 20 at any time as needed. The first positioning member 93 is sleeved on the outer peripheral side of the lampshade 91, the first sealing ring 94 is sealed between the first positioning member 93 and the side groove wall of the first mounting groove 29, and the second sealing ring 95 is sealed between the first positioning member 93 and the outer peripheral side of the lampshade 91. In this way, the lampshade 91 can be installed in the first mounting groove 29. Since the head of the lampshade 91 is exposed to the clean water tank 20 through the first mounting opening 291, and the sterilizing lamp 96 extends into the inner side of the lampshade 91 when the clean water tank 20 is supported on the support 81, when the clean water tank 20 is supported on the support 81, the light emitted by the sterilizing lamp 96 located inside the lampshade 91 passes through the lampshade 91 and irradiates the clean water tank 20 to sterilize the water stored in the clean water tank 20.

[0336] In addition, the lampshade positioning assembly 92 includes a first positioning member 93, a first sealing ring 94 and a second sealing ring 95 respectively disposed on the outer and inner sides of the first positioning member 93. The first positioning member 93 serves as a supporting framework, and the first and second sealing rings 94 and 95 primarily function as deformation seals. Compared with the related art that uses only a sealing ring 35, in which the entire sealing ring 35 has a larger radial thickness, the radial thickness of the deformed first and second sealing rings 94 and 95 is smaller, which slows down the degree and speed of aging, thereby improving the reliability of the seal. As the use time increases, the possibility of water leakage is reduced.

[0337] For example, the lampshade 91 is a light-transmitting structure, for example, the head of the lampshade 91 can be inserted into the clean water tank 20 through the first mounting opening 291, so that the germicidal lamp 96 can irradiate water in a wider range. The germicidal lamp 96 can be, for example, an ultraviolet germicidal lamp.

[0338] In a specific implementation, the hardness of the first positioning member 93 is greater than that of the first sealing ring 94 and the second sealing ring 95. This can further reduce the aging rate of the lampshade 91 mounting assembly and improve the overall strength of the lampshade 91 mounting assembly. For example, the first positioning member 93 can be configured as a metal member, and the first sealing ring 94 and the second sealing ring 95 can be configured as rubber members.

[0339] Of course, to enhance sealing, there are at least two first sealing rings 94, with at least two first sealing rings 94 arranged axially along the first positioning member 93. Similarly, there are at least two second sealing rings 95, with at least two second sealing rings 95 arranged axially along the first positioning member 93. This provides multiple lines of defense along the axial direction of the first positioning member 93, minimizing the occurrence of water leakage.

[0340] Continuing with FIG19 , when there are multiple first sealing rings 94 and second sealing rings 95, in order to position them in the axial direction, it is conceivable to provide at least one annular second mounting groove 932 on the outer circumference of the first positioning member 93, with the first sealing rings 94 being mounted in the second mounting groove 932 in a one-to-one correspondence. This prevents the first sealing rings 94 from moving in the axial direction of the first positioning member 93.

[0341] The inner circumference of the first positioning member 93 is provided with at least one annular stopper 931. The stopper 931 and the inner circumference of the first positioning member 93 define a semi-open annular installation space J. The second sealing ring 95 is installed in the annular installation space J. In this way, the stopper 931 and the sealing member 97 together form an installation space for installing the second sealing ring 95.

[0342] In the embodiment of the present application, referring to Figures 18 and 19 , the lampshade positioning assembly 92 further includes a sealing member 97. The sealing member 97 is connected to the end of the first positioning member 93 facing the clean water tank 20 and is disposed on the side of the second sealing ring 95 facing the clean water tank 20. In this way, the second sealing ring 95 is prevented from being separated from the gap between the first positioning member 93 and the lampshade 91.

[0343] Regarding the connection between the sealing member 97 and the first positioning member 93, for example, the sealing member 97 may be provided with a clamping arm 973, and the first positioning member 93 may be provided with a clamping groove 974. The sealing member 97 and the first positioning member 93 are connected by the clamping engagement between the clamping arm 973 and the clamping groove 974. In this way, the first positioning member 93 and the sealing member 97 can be reliably connected as one body.

[0344] Furthermore, the sealing member 97 is provided with an annular first abutting portion 971 and a second abutting portion 972 at the axial end of the first positioning member 93. The first abutting portion 971 is configured to abut the second sealing ring 95, and the second abutting portion 972 is configured to abut the end of the lampshade 91 facing the purified water tank 20. This prevents the second sealing ring 95 from moving axially in the first positioning member 93 and prevents the lampshade 91 from being separated from the first mounting groove 29.

[0345] Continuing with FIG18 , the germicidal lamp 96 includes a germicidal lamp mounting bracket 961 and a lamp body 962. The germicidal lamp mounting bracket 961 is mounted on the outer wall of the housing 80 at a position corresponding to the first mounting opening 291, and the lamp body 962 is mounted on the end of the germicidal lamp mounting bracket 961 facing the purified water tank 20. This allows the germicidal lamp 96 to be mounted at a position corresponding to the lampshade 91.

[0346] Of course, a second mounting opening 8732 is provided on the housing 80 so that the germicidal lamp mounting bracket 961 can pass through the second mounting opening 8732 and extend out of the housing 80 .

[0347] 17 , the first mounting opening 291 and the clean water tank communication opening 21 are both located between the top and bottom of the clean water tank 20, with the first mounting opening 291 being positioned higher than the clean water tank communication opening 21. This allows the germicidal light emitted by the germicidal lamp 96 to cover the water in the clean water tank 20 as much as possible.

[0348] Figure 20 is a cross-sectional view of another structure of the water purification tank 20 in the water purifier 100 provided in an embodiment of the present application, Figure 21 is a cross-sectional view of another angle of another structure of the water purification tank 20 in the water purifier 100 provided in an embodiment of the present application, and Figure 22 is a partial enlarged view of point Y in Figure 21.

[0349] 20, 21 and 22, in the aforementioned solution, it is necessary to drill a hole in the front panel 873 and install a germicidal lamp 96, which affects the user's visual experience. Therefore, it may be considered to set the sterilization unit 90 to a wireless mode.

[0350] In a specific implementation, the sterilization unit 90 may include a lamp holder 98, which is inserted into the first mounting opening 291 and sealed therewith. For example, a flange 982 may be provided at the first end of the lamp holder 98, which overlaps the edge of the first mounting opening 291, and a third sealing ring 981 is provided between the flange 982 and the edge of the first mounting opening 291. In this case, the germicidal lamp 96 may be installed at the end of the lamp holder 98 facing the inside of the clean water tank 20. This allows the germicidal lamp 96 to extend directly into the interior of the clean water tank 20, thereby providing a wider irradiation range within the clean water tank 20 than in the previous embodiment.

[0351] 22 , the sterilization unit 90 further includes a second mounting member 983 sleeved on the lamp holder 98. The second mounting member 983 can be located outside the clean water tank 20, for example, within the first mounting groove 29, and is used to apply a force toward the outside of the clean water tank 20 to the flange portion 982 so that the flange portion 982 presses the third sealing ring 981 against the inner wall of the clean water tank 20. In actual application, the second mounting member 983 can rest against the bottom wall of the first mounting groove 29, and the second mounting member 983 and the lamp holder 98 can be threadedly engaged. At this time, the flange portion 982, the first sealing ring 94, and the second mounting member 983 are respectively pressed against the bottom of the first mounting groove 29 from the inner and outer sides of the clean water tank 20.

[0352] In order to position the germicidal lamp 96, an installation groove is formed at the end of the lamp holder 98 facing the inner side of the clean water tank 20, and the germicidal lamp 96 is sealed and installed in the installation groove.

[0353] In the embodiment of the present application, the sterilization unit 90 further includes a wireless component 99, which includes a wireless transmitting unit 991 and a wireless receiving unit 992. The wireless transmitting unit 991 is mounted on the inner wall of the housing 80 and is electrically connected to the power supply circuit board (not shown) of the water purifier 100. The wireless receiving unit 992 is mounted on the end of the lamp holder 98 facing the outside of the clean water tank 20. When the clean water tank 20 is supported on the support member 81, the wireless transmitting unit 991 and the wireless receiving unit 992 are arranged relative to each other to supply power to the sterilization lamp 96 via the wireless receiving unit 992.

[0354] Figure 23 is a schematic structural diagram of a water vapor separator provided in an embodiment of the present application; Figure 24a is a schematic cross-sectional structural diagram of a water vapor separator provided in an embodiment of the present application; Figure 24b is a schematic structural diagram of a water purifier provided in an embodiment of the present application from another angle; Figure 25 is a partial enlarged view of position Z in Figure 24a; Figure 26 is a schematic structural diagram of a water vapor separator provided in an embodiment of the present application from another angle; Figure 27 is a partial cross-sectional view of a water vapor separator provided in an embodiment of the present application; Figure 28 is a cross-sectional view of a water vapor separator provided in an embodiment of the present application from another angle. It will be understood that, in order to facilitate observation of the internal structure, Figure 26 shows a schematic diagram of the first-stage separator cover 641 in an open state relative to the first-stage separator main body 64.

[0355] In the embodiment of the present application, as described above, the water vapor separator 60 is used to separate the steam in the heated purified water. The water vapor separator 60 is provided with a water vapor separation outlet 61 , which forms the water inlet of the water purifier 100 .

[0356] The water vapor separator in the related art has the problem of poor steam separation effect. The water flowing out from the water vapor separation outlet contains a lot of steam. In order to avoid this problem, the water purifier in the related art often controls the outlet water temperature at around 93°C to reduce the steam content in the outlet water. Therefore, the water purifier in the related art has the problem that the outlet water temperature is not high enough.

[0357] In order to solve this problem, the embodiment of the present application further improves the structure of the water vapor separator 60.

[0358] Specifically, in combination with Figures 23, 24a, and 25, the water vapor separator 60 includes a primary water vapor separation body 63 and a secondary water vapor separation body 65 for performing water vapor separation. The primary water vapor separation body 63 and the secondary water vapor separation body 65 are respectively constructed with a primary water vapor separation chamber K and a secondary water vapor separation chamber L that are interconnected.

[0359] The first-level water vapor separation body 63 is provided with a water vapor separation water inlet 631 and a first air outlet 632 connected to the first-level water vapor separation chamber K, while the water vapor separation water outlet 61 and the water vapor separation air outlet 62 are arranged on the second-level water vapor separation body 65 and connected to the second-level water vapor separation chamber L. The water vapor separation water inlet 631 is used to connect to the hot water supply source.

[0360] The water vapor separation water inlet 631 is arranged on the bottom wall 633 of the first-level water vapor separation chamber. The bottom wall 633 of the first-level water vapor separation chamber is provided with a first guide tube 635 extending toward the top wall 634 of the first-level water vapor separation chamber. The first guide tube 635 is connected to the water vapor separation water inlet 631. The top wall 634 of the first-level water vapor separation chamber is also provided with a guide wall 66 extending toward the bottom wall 633 of the first-level water vapor separation chamber. The guide wall 66 is blocked on the circumferential outside of at least part of the pipe section of the first guide tube 635.

[0361] The water vapor separator 60 includes a primary water vapor separation body 63 and a secondary water vapor separation body 65 for water vapor separation. The primary water vapor separation chamber K in the primary water vapor separation body 63 and the secondary water vapor separation chamber L in the secondary water vapor separation body 65 are connected to each other. In this way, the water vapor mixture first enters the primary water vapor separation body 63 for a first water vapor separation, and then enters the secondary water vapor separation body 65 for a second water vapor separation, and the water vapor separation effect is better.

[0362] On the other hand, the water vapor separation water inlet 631 is set on the bottom wall 633 of the first-level water vapor separation chamber, and the bottom wall 633 of the first-level water vapor separation chamber is provided with a first guide tube 635 extending toward the top wall 634 of the first-level water vapor separation chamber. In this way, the water vapor mixture entering the first-level water vapor separation chamber K from the water vapor separation water inlet 631 enters the first guide tube 635. In addition, the top wall 634 of the primary water vapor separation chamber is further provided with a drainage wall 66 extending toward the bottom wall 633 of the primary water vapor separation chamber. The drainage wall 66 is disposed on the circumferential outer side of at least a portion of the first flow conduit 635. As a result, after the water vapor mixture in the first flow conduit 635 escapes from the first flow conduit 635, it rushes toward the top wall 634 of the primary water vapor separation chamber. The top wall 634 of the primary water vapor separation chamber can break up the water vapor mixture, separating some of the steam in the water vapor mixture from the water flow. The water then flows downward along the drainage wall 66 into the bottom of the primary water vapor separation chamber K, and the steam is discharged upward from the primary water vapor separation body 63 through the first outlet 632. As described above, when the water vapor separation effect is good, the amount of steam contained in the water is low, and the water outlet temperature of the water purifier can be set higher to meet the user's water needs.

[0363] The hot water source may be, for example, a heater 55, whose water outlet 551 may be connected to the water vapor separation water inlet 631 via the fifth pipe 105. Of course, in other embodiments, the water outlet 551 may also be directly connected to the water vapor separation water inlet 631.

[0364] In the embodiment of the present application, the setting height of the bottom end of the guide wall 66 facing the bottom wall 633 of the first water vapor separation chamber is lower than the setting height of the top end of the first guide pipe 635 facing the first water vapor separation chamber K.

[0365] By making the bottom end of the guide wall 66 lower than the top end of the first guide tube 635, it can be ensured that the water vapor mixture rushing out of the first guide tube 635 can be broken up by the top wall 634 of the first-level water vapor separation chamber, and the broken up water flow can reliably fall along the guide wall 66 onto the bottom wall 633 of the first-level water vapor separation chamber, and will not enter the first guide tube 635 from the top end of the first guide tube 635.

[0366] Further, referring to FIG. 27 , the guide wall 66 and a portion of the side wall 636 of the primary water vapor separation chamber define a scattered cavity M, and a portion of the top side of the first guide pipe 635 extends into the scattered cavity M.

[0367] In some embodiments, at least a portion of the outer tube wall of the first flow guide tube 635 and the inner wall of the first-stage water vapor separation chamber K are constructed as an integral piece to facilitate the processing and manufacturing process.

[0368] 24a and 27 , further, a first mounting pipe 637 is provided on the outer wall of the primary water vapor separator 63, which is coaxial with and communicates with the first flow conduit 635. This facilitates the introduction of the water vapor mixture flowing out of the water outlet 551 of the heater into the first flow conduit 635.

[0369] Furthermore, the first air outlet 632 is provided on a side wall 636 of the primary moisture separation chamber. A second flow guide tube 638 is provided on the side wall 636 of the primary moisture separation chamber, extending toward the top wall 634 of the primary moisture separation chamber. The second flow guide tube 638 is connected to the first air outlet 632. A flow guide wall 66 extends between the first flow guide tube 635 and the second flow guide tube 638. The top end of the first flow guide tube 635 is separated from the top end of the second flow guide tube 638 by the flow guide wall 66.

[0370] With such an arrangement, the bottom end of the guide wall 66 is actually arranged at a height lower than the top end of the second guide tube 638. After the water vapor mixture flushed out through the first guide tube 635 is broken up by the top wall 634 of the first-level water vapor separation chamber, the water flows downward from the guide wall 66 toward one side of the first guide tube 635. Due to the obstruction of the guide wall 66, it will not enter the second guide tube 638.

[0371] Similar to the first flow guide tube 635 , at least a portion of the outer tube wall of the second flow guide tube 638 and the inner wall of the first-stage water vapor separation chamber K are constructed as an integral piece, which facilitates the processing and manufacturing process.

[0372] In this embodiment, a second mounting tube 639 is provided on the outer wall of the primary vapor separator 63, coaxial with and interconnected with the second flow guide tube 638. This facilitates the degassing of steam out of the primary vapor separation chamber K. In a specific implementation, for example, referring to FIG. 24a , the second mounting tube 639 can be connected to the vapor separation outlet 62 on the secondary vapor separator 65 via the sixth conduit 106.

[0373] 26 and 27 , the primary water vapor separator 63 further includes a primary separator body 64 and a primary separator cover 641 covering the primary separator body 64. The guide wall 66 is provided on the primary separator cover 641. This arrangement can facilitate the processing.

[0374] 24a, 27 and 28, the first-level water vapor separation body 63 is provided with a first connecting port 642 communicating with the first-level water vapor separation chamber K, and the second-level water vapor separation body 65 is provided with a second connecting port 651 communicating with the second-level water vapor separation chamber L, and the first connecting port 642 is communicated with the second connecting port 651.

[0375] The top wall 652 of the secondary moisture separation chamber is further provided with a third flow guide tube 655 extending toward the bottom wall 653 of the secondary moisture separation chamber. The third flow guide tube 655 is connected to the second connection port 651. The bottom wall 653 of the secondary moisture separation chamber is provided with a stopper wall 654 extending toward the top wall 652 of the secondary moisture separation chamber. The stopper wall 654 is located between the circumferential outer side of the third flow guide tube 655 and the moisture separation outlet 61.

[0376] A third flow guide 655 extending toward the bottom wall 653 of the secondary water vapor separation chamber is provided through the top wall 652 of the secondary water vapor separation chamber. Water flowing out of the primary water vapor separation chamber K falls onto the bottom wall 653 of the secondary water vapor separation chamber and is broken up again, so that part of the steam mixed in the water flow is separated from the water flow. The bottom wall 653 of the secondary water vapor separation chamber is provided with a stop wall 654 extending toward the top wall of the secondary water vapor separation chamber. The stop wall 654 is provided around the third flow guide 655. The water flow, which has been dispersed and separated on the bottom wall 653 of the secondary water vapor separation chamber, hits the stop wall 654 as it flows toward the water vapor separation outlet 61, and is dispersed again, undergoing water vapor separation. The separated steam then flows out of the secondary water vapor separation chamber L through the water vapor separation outlet 62. The water flow, which has been dispersed again after passing through the stop wall 654, now contains a lower amount of steam and can flow out of the secondary water vapor separation chamber L through the water vapor separation outlet 61. In this way, the water flow entering the secondary water vapor separation chamber L, after undergoing two water vapor separations, is used in combination with the primary water vapor separator 63 to achieve a better water vapor separation effect on hot water.

[0377] 24a and 28 , further, the bottom wall 653 of the secondary water vapor separation chamber is constructed with a retention groove N spaced apart from the water vapor separation outlet, and the bottom end of the third guide pipe 655 extends into the retention groove N.

[0378] By making the bottom end of the third flow conduit 655 extend into the retention tank N, that is, the height of the bottom end of the third flow conduit 655 is lower than the height of the edge of the notch of the retention tank N. In this way, when water intake stops, the water flowing out of the primary water vapor separation chamber K will rush out of the third flow conduit 655 due to the inertia of the water flow and the adhesion of water, causing the water level in the third flow conduit 655 to be lower than the water level in the retention tank N (which is full of water). As time goes by, the water in the third flow conduit 655 gradually stabilizes, and some of the water in the retention tank N returns to the third flow conduit 655, making the water level in the third flow conduit 655 equal to the water level in the retention tank N, thereby lowering the water level in the retention tank N. The portion below the edge of the slot is not full. At this time, if there are residual water droplets in the first-level water vapor separation chamber K and they drip into the second-level water vapor separation body 65, the water levels in the retention slot N and the third guide tube 655 will rise accordingly. However, due to the viscosity of water, it will adhere to the side slot wall of the retention slot N, that is, the water in the retention slot N will not flow out. Therefore, no water droplets will drip from the water vapor separation outlet 61. In this way, the effect of quickly sealing the water when stopping water intake is achieved, effectively improving the problem of water leakage at the water intake of the water purifier 100.

[0379] In the prior art, air easily enters the inner cavity of the water vapor separator 60 through the water vapor separation outlet 61, which can easily breed bacteria over time. Furthermore, since this inner cavity is inaccessible to users, the retention groove N is provided. Therefore, after water withdrawal stops, the bottom end of the third flow guide tube 655 extends into the retention groove N, creating a liquid seal. This prevents outside air from entering the inner cavity of the water vapor separator 60, particularly the primary water vapor separator 63, inhibiting bacterial growth and ensuring cleaner and more hygienic water output from the water vapor separator 60.

[0380] In some embodiments, the stop wall 654 and a portion of the side wall 656 of the secondary water vapor separation chamber define the aforementioned retention groove N. This configuration can reduce the volume of the secondary water vapor separation body 65 compared to a groove formed on the bottom wall 653 of the secondary water vapor separation chamber.

[0381] In combination with Figures 23 and 24a, further, a first matching tube 657 connected to the first connecting port 642 is provided on the outer wall of the first water vapor separation body 63, and a first matching slot 658 connected to the second connecting port 651 is provided on the second water vapor separation body 65. The first matching tube 657 and the first matching slot 658 are plugged into each other to connect the first connecting port 642 and the second connecting port 651.

[0382] It can be understood that in order to avoid water leakage between the first mating tube 657 and the first mating slot 658, a seal 660 can be provided between the outer wall of the first mating tube 657 and the inner groove wall of the first mating slot 658. The seal 660 can be an annular sealing ring, which is mounted on the outer periphery of the first mating tube 657 and clamped between the first mating tube 657 and the first mating slot 658.

[0383] In this way, the primary water vapor separator 63 and the secondary water vapor separator 65 are plugged and mated, making the fit relatively secure. Of course, it is understood that, referring to Figure 23 , the primary water vapor separator 63 and the secondary water vapor separator 65 can also be fixedly connected by fasteners 643 to further secure the connection. The outer circumferential wall of the first mating tube 657 can also be provided with a plurality of circumferentially spaced positioning ribs 659. The positioning ribs 659 abut against the notches of the first mating slot 658 to assist in positioning the first mating tube 657 and the first mating slot 658.

[0384] In combination with Figures 23 and 24a, further, the secondary water vapor separation body 65 includes a secondary water vapor separation body 671 and a secondary water vapor separation cover body 673 covered on the secondary water vapor separation body 671, the first mating slot 658 is arranged on the top side of the secondary water vapor separation cover body 673, and the third guide tube 655 is arranged on the bottom side of the secondary water vapor separation cover body 673 and is connected to the first mating slot 658.

[0385] Thus, after the first matching tube 657 is inserted into the first matching slot 658, water flowing out of the first matching tube 657 can directly enter the third flow guide tube 655. In a specific implementation, the first matching tube 657 and the third flow guide tube 655 can be coaxially arranged.

[0386] Furthermore, the water vapor separation outlet 61 is disposed on the bottom wall 653 of the secondary water vapor separation chamber. The bottom wall 653 of the secondary water vapor separation chamber is configured as an inclined wall structure that tilts toward the water vapor separation outlet 61. In this way, water flowing out of the retention tank N can more easily flow along the inclined wall into the water vapor separation outlet 61.

[0387] 24a and 27 , further, the water vapor separation outlet 62 is provided on the bottom wall 653 of the secondary water vapor separation chamber and is located between the water vapor separation outlet 61 and the stop wall 654 ;

[0388] A fourth flow guide tube 672 extending toward the top wall 652 of the secondary water vapor separation chamber is provided on the bottom wall 653 of the secondary water vapor separation chamber. The fourth flow guide tube 672 is connected to the water vapor separation outlet 62, and a distance is provided between the top end of the fourth flow guide tube 672 and the top wall 652 of the secondary water vapor separation chamber.

[0389] In this way, the steam separated in the secondary water vapor separation chamber L rises upward and gathers at the top of the secondary water vapor separation chamber L. It can enter the fourth guide tube 672 from the top end of the fourth guide tube 672 and flow out of the secondary water vapor separation chamber L from the water vapor separation outlet 62.

[0390] Furthermore, the water vapor separation air outlet 62 is located on the bottom wall 653 of the secondary water vapor separation chamber near the water vapor separation water outlet 61 .

[0391] In the embodiment of the present application, an avoidance recess O is provided on the inner wall of the secondary water vapor separation cover 673 at a position corresponding to the fourth guide tube 672 , and the top end of the fourth guide tube 672 extends into the avoidance recess O.

[0392] In this way, even if the length of the fourth guide pipe 672 is longer, the external contour size of the secondary water vapor separation body 65 will not be increased.

[0393] Furthermore, the water vapor separation outlet 62 is located between the water vapor separation outlet 61 and the second connecting port 651 , and the first connecting port 642 corresponds to the second connecting port 651 .

[0394] Furthermore, the water vapor separation outlet 61 , the water vapor separation air outlet 62 and the first connecting port 642 are arranged in a row.

[0395] Referring to Figure 24b, as previously described, the outer wall of the housing 80 is provided with a carrier 81, on which a water collection box 85 is formed. When drawing water, the user can place a water container on the water collection box 85 to draw water from the water vapor separation outlet 61. The water vapor separator 60, particularly the water vapor separation outlet 61 and the water vapor separation air outlet 62, must be positioned above the carrier 81 (water collection box 85) and aligned with the position of the carrier 81.

[0396] Of course, as mentioned above, an avoidance gap needs to be set on the shell 80 to allow part of the structure of the water vapor separator 60 to be exposed to the outside of the shell 80. For example, the water vapor separation outlet 61 and the water vapor separation gas outlet 62 need to be located on the outside of the shell 80. On the one hand, it is convenient to take water, and on the other hand, it is also convenient to prevent the discharged gas from entering the interior of the shell 80 and affecting the various components inside the shell 80.

[0397] Furthermore, the first connection port 642 is disposed on the bottom wall 633 of the primary moisture separation chamber, which is configured as an inclined structure that slopes toward the first connection port 642. This allows water flowing downward from the drainage wall 66 to more easily flow out of the primary moisture separation chamber K through the first connection port 642. As previously described, the moisture separation water inlet 631 and the first connection port 642 are both located on the bottom wall 633 of the primary moisture separation chamber, but the moisture separation water inlet 631 is positioned higher than the first connection port 642, allowing the fluid flowing out of the first guide pipe 635 to be more easily directed from the bottom wall 633 of the primary moisture separation chamber to the first connection port 642.

[0398] Furthermore, as previously mentioned, the water vapor separation outlet 62 can communicate with the interior of the filter housing 42. Thus, the steam discharged from the water vapor separation outlet 62 can be discharged into the atmosphere through the filter housing 42. Of course, as another possible embodiment, the water vapor separator 60 can be partially disposed within the housing 80, with the water vapor separation outlet 61 and the water vapor separation outlet 62 both disposed outside the housing 80. This arrangement facilitates the dissipation of steam discharged from the water vapor separation outlet 62 outside the housing.

[0399] In addition, in the embodiment of the present application, the cross-sectional area of ​​the water vapor separation outlet 62 is greater than or equal to 22 mm 2 Since the steam discharged from the water vapor separation outlet 62 will form condensed water after contacting the outside air, the condensed water can directly flow into the water cup outside. If the cross-sectional area of ​​the water vapor separation outlet 62 is too small, the condensed water will form a water film when passing through the water vapor separation outlet 62, making it difficult to exhaust, causing the steam to be discharged from the water vapor separation outlet 61 together with the water flow, resulting in interruption and jetting. When the cross-sectional area of ​​the water vapor separation outlet 62 is greater than or equal to 22mm 2 This situation can be avoided.

[0400] Furthermore, the cross-sectional area of ​​the first connection port 642 is greater than or equal to 22 mm 2 This can prevent the water from forming a water film due to the small cross-sectional area when the water flows out of the first water vapor separation chamber M through the first connecting port 642, resulting in poor drainage.

[0401] The working process of the water-cut-off operation of the water vapor separator 60 will be described below with reference to FIG. 28 .

[0402] In FIG28 , the water shutoff process of the water vapor separator is divided into six states.

[0403] State (a) is the water level state during water production.

[0404] State (b) corresponds to the moment when water intake stops. The water flowing out of the first-level water vapor separation chamber K will rush out of the third guide pipe 655 due to the water flow inertia and the adhesion characteristics of water, causing the water level of the third guide pipe 655 to be lower than the water level in the retention tank N.

[0405] State (c) is that as time goes by, the water in the third guide tube 655 gradually stabilizes, and part of the water in the retention tank N returns to the third guide tube 655, so that the water level in the third guide tube 655 is level with the water level in the retention tank N, so that the water level in the retention tank N is lower than the top end of the stop wall 654.

[0406] In state (d), if there are residual water droplets in the first-level water vapor separation chamber K and drip into the second-level water vapor separation body 65, the water level in the retention tank N and the third guide tube 655 will rise accordingly. However, due to the viscosity of water, it will adhere to the side of the stop wall 654 close to the retention tank N, that is, the water in the retention tank N will not exceed the stop wall 654, so no water droplets will drip from the water vapor separation outlet 61. In this way, the effect of quickly sealing the water when water extraction is stopped is achieved.

[0407] State (e) corresponds to a schematic diagram in which the stopping wall 654 blocks the dripping water in the retention groove.

[0408] A split-type UV sterilization module as shown in FIG. 29 to FIG. 31 includes a lampshade module 9 - 1 and a sterilization module 9 - 2 .

[0409] The lampshade module 9-1 includes a fixing ring 9-11, a transparent outer cover 9-12, a bottom cover 9-13, a first sealing ring 9-14 and a second sealing ring 9-15. The outer cover 9-12 is made of quartz glass. The fixing ring 9-11 is sleeved on the outer surface of the outer cover 9-12. The bottom cover 9-13 is arranged at the lower end between the fixing ring 9-11 and the outer cover 9-12. The first sealing ring 9-14 is fixedly arranged between the fixing ring 9-11 and the outer cover 9-12.

[0410] The second sealing ring 9-15 is located on the outer side of the fixing ring 9-11. The specific structure is: a sealing groove 9-111 is opened around the outer side of the fixing ring 9-11, and the second sealing ring 9-15 is located in the sealing groove 9-111.

[0411] A buckle groove 9-112 is provided on the side of the fixing ring 9-11, and a clamping block 9-131 is fixedly provided on the outer side of the bottom cover 9-13, and the clamping block 9-131 is clamped in the buckle groove 9-112.

[0412] During actual use, first drill a mounting hole at the corresponding position of the clean water tank, fix the fixing ring 9-11 in the mounting hole on the clean water tank, and use the second sealing ring 9-15 to achieve the seal between the fixing ring 9-11 and the clean water tank, then pass the outer cover 9-12 into the center of the fixing ring 9-11, and use the first sealing ring 9-14 to achieve the seal between the fixing ring 9-11 and the outer cover 9-12, and finally cover the bottom cover 9-13 between the fixing ring 9-11 and the outer cover 9-12, and make the block 9-131 on the bottom cover 9-13 be stuck in the buckle groove 9-112, so that the lampshade module 9-1 is fixed on the clean water tank as a whole.

[0413] The sterilization module 9-2 includes a UV lamp 9-21, a fixing seat 9-22, an inner cover 9-23, an inner silicone seat 9-24, and a wire 9-25. The UV lamp 9-21 is fixedly set on the fixing seat 9-22, and the UV lamp 9-21 extends into the interior of the outer cover 9-12. The specific structure is: the inner cover 9-23 is fixedly set on the fixing seat 9-22, and the inner cover 9-23 has an opening at one end close to the fixing seat 9-22. The UV lamp 9-21 is located inside the inner cover 9-23, and the inner silicone seat 9-24 is fixedly set at the opening.

[0414] Since the outer cover 9-12 is transparent, the UV lamp 9-21 extends into the interior of the outer cover 9-12. When the UV lamp 9-21 is working, the ultraviolet light emitted passes through the outer cover 9-12 and enters the interior of the clean water tank, thereby sterilizing the water in the clean water tank.

[0415] The wire 9-25 passes through the fixing seat 9-22 and the inner silicone seat 9-24 in turn, and is electrically connected to the UV lamp 9-21. The inside of the fixing seat 9-22 is filled with resin. After the resin solidifies, the wire 9-25 is fixed inside the fixing seat 9-22, and at the same time, the inner cover 9-23, the inner silicone seat 9-24 and the fixing seat 9-22 are fixed as one.

[0416] Since the sterilization module 9-2 is entirely arranged outside the water purification tank, the wire 9-25 is laid out from the outside of the water purification tank, which does not affect the aesthetics of the water purification tank. Compared with the traditional technology of hanging too many and too long pipes or wires into the water purification tank, this application achieves the purpose of not affecting the aesthetics of the water purification tank.

[0417] A hanging ear 9-221 is also fixedly provided on the fixing seat 9-22, and a perforation 9-222 is opened on the hanging ear 9-221. The sterilization module 9-2 can be fixedly set on the equipment outside the water purification tank through the hanging ear 9-221, thereby realizing the split installation of the lampshade module 9-1 and the sterilization module 9-2.

[0418] The working principle of the split-type UV sterilization module of this embodiment is as follows: in actual use, first drill a mounting hole at the corresponding position of the clean water tank, fix the fixing ring 9-11 in the mounting hole on the clean water tank, and use the second sealing ring 9-15 to achieve the seal between the fixing ring 9-11 and the clean water tank, then insert the outer cover 9-12 into the center of the fixing ring 9-11, and use the first sealing ring 9-14 to achieve the seal between the fixing ring 9-11 and the outer cover 9-12, and finally fix the bottom cover. 9-13 is covered between the fixing ring 9-11 and the outer cover 9-12, and the block 9-131 on the bottom cover 9-13 is clamped in the buckle groove 9-112, so that the lampshade module 9-1 is fixed on the clean water tank as a whole; then the inner cover 9-23 is extended into the outer cover 12, so that the UV lamp 9-21 is extended into the outer cover 9-12. When the UV lamp 9-21 is working, the ultraviolet light emitted is shot into the inside of the clean water tank through the outer cover 9-12, which has the effect of sterilizing the water in the clean water tank.

[0419] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, several variations and improvements can be made, which all fall within the scope of protection of the present application. Therefore, the scope of protection of the patent application of this application shall be based on the attached claims.
