[0033] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0034] The orientations or positional relationships described below are for the convenience of describing this disclosure and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this disclosure. Specifically, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly, for example, they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0036] Figure 1 This is a partial enlarged view of a drainage device according to an illustrative embodiment of the present disclosure. Figure 2 This is a perspective view of a water receiving tray according to an illustrative embodiment of the present disclosure.

[0037] Reference Figure 1 and Figure 2 As shown, this utility model provides a drainage device. The drainage device may include a water receiving tray 1, a connecting part 2, and a drainage pump 3. The water receiving tray 1 may form a receiving space 14 for containing liquid. The connecting part 2 may include an internal end 21 and an external end 22. The internal end 21 may be disposed within the receiving space 14. The external end 22 may be disposed on the outer wall 11 of the water receiving tray 1. The drainage pump 3 may be disposed within the receiving space 14 based on the connecting part 2. By operating the external end 22, the connecting part 2 and the drainage pump 3 can be connected to or disconnected from the water receiving tray 1. The drainage pump 3 can be used to drain the liquid in the water receiving tray 1.

[0038] In some illustrative embodiments, an external device can deliver liquid to be discharged into the water receiving tray 1. The water receiving tray 1 includes, but is not limited to, a cuboid structure configured with a water storage opening 15. (Refer to...) Figure 2 As shown, the water receiving tray 1 has a base plate 13 and an outer wall 11 extending upward from the outer periphery of the base plate 13. The upper edge of the outer wall 11 forms a water storage opening 15 on the side opposite to the base plate 13, allowing liquid to enter. It should be understood that the embodiments of this disclosure are not limited thereto.

[0039] For example, the water receiving tray 1 can also be configured as a cylinder, elliptical cylinder, or other body structure suitable for receiving and containing liquids, with a water storage opening 15.

[0040] In some illustrative embodiments, the drain pump 3 includes, but is not limited to, being configured as a cylinder.

[0041] For example, the drain pump 3 can also be configured as a cuboid, an elliptical cylinder, or other structures suitable for draining liquids.

[0042] According to the embodiments of this disclosure, by providing the connecting part 2, the drain pump 3 can be placed within the receiving space 14 of the water receiving tray 1, so as to discharge the liquid in the water receiving tray 1 using the drain pump 3. By providing the internal end 21 of the connecting part 2 within the receiving space 14 and the external end 22 of the connecting part 2 on the outer wall 11 of the water receiving tray 1, the connecting part 2 and the drain pump 3 can be connected or disconnected from the water receiving tray 1 by operating the external end 22. Thus, the drain pump 3 can be installed or removed from the outside of the water receiving tray 1 without having to extend into the inside of the water receiving tray 1, which improves the convenience and safety of installing or removing the drain pump 3.

[0043] In some illustrative embodiments, the bottom surface 12 of the water tray 1, facing the water inlet 311, has a recessed portion 121 that is recessed downward from the bottom surface 12.

[0044] Reference Figure 2As shown, a recess 121 can be formed within the receiving space 14. The drain pump 3 can be located above the recess 121. The recess 121 can be formed at the lowest point of the bottom surface 12 of the water receiving tray 1. Specifically, the bottom surface 12 of the water receiving tray 1 can be formed as an inclined surface sloping downward toward the recess 121. In this way, the liquid stored in the water receiving tray 1 can gather toward the recess 121 under the action of gravity and enter the drain pump 3 through the water inlet 311.

[0045] Figure 3 This is a perspective view of a flexible member and a drainage pump according to an illustrative embodiment of the present disclosure. Figure 4 yes Figure 3 A perspective view of another embodiment shown.

[0046] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some illustrative embodiments, the connecting portion 2 may include a flexible member 23 and a locking member 24. The flexible member 23 includes an internal end 21, a connecting end 25, and a fixing block 210. The connecting end 25 is connected to the locking member 24. The fixing block 210 may be located between the internal end 21 and the locking member 24. The fixing block 210 is connected to the drain pump 3 to house the drain pump 3 within the receiving space 14. The locking member 24 may include an external end 22 and a mating end 26 connected to the flexible member 23.

[0047] In some illustrative embodiments, the flexible element 23 can be made of flexible materials such as silicone, hydrogel, and fluororubber. Since the drain pump 3 is connected to the locking element 24 and the water receiving tray 1 based on the flexible element 23, the vibration of the drain pump 3 is transmitted to the flexible element 23 during operation. Because the flexible element 23 is made of a flexible material, it can release the force generated by the vibration through deformation, thus preventing the vibration from being transmitted to the water receiving tray 1 and reducing noise.

[0048] Reference Figure 3 and Figure 4 As shown, in some illustrative embodiments, a retaining block 210 surrounds the drain pump 3. An internal end 21 and a connecting end 25 are located on opposite outer sides of the retaining block 210. The retaining block 210 can be configured as an annular structure that matches the outer peripheral contour of the drain pump 3. It should be understood that the embodiments of this disclosure are not limited thereto.

[0049] Furthermore, the fixing block 210 can also be configured as other flexible structures suitable for connecting the drain pump 3 to the locking member 24 and the water receiving tray 1 respectively. For example, the fixing block 210 can be configured as a split structure comprising two parts, one part for connecting the drain pump 3 to the locking member 24 and the other part for connecting the drain pump 3 to the water receiving tray 1.

[0050] In some illustrative embodiments, the connecting portion 2 may be distinguished from the separate structure of the flexible member 23 and the locking member 24; the connecting portion 2 may be an integral rigid or flexible structure. The connecting portion 2 may be any structure capable of being installed at one end within the receiving space 14 and at the other end onto the outer wall 11 of the water receiving tray 1.

[0051] Figure 5 yes Figure 2 A partially enlarged view of the schematic embodiment shown.

[0052] Reference Figure 2 and Figure 5 As shown, in some illustrative embodiments, a fixing portion 4 extending perpendicularly to the bottom surface 12 of the water receiving tray 1 may be formed within the receiving space 14. The fixing portion 4 is formed with a first mounting ring 41 suitable for receiving the built-in end 21.

[0053] Reference Figure 1 and Figure 5 As shown, the fixing part 4 can be configured as a columnar structure. The flexible member 23 holds the drain pump 3 within the receiving space 14 via the fixing part 4. The opening profile of the first mounting ring 41 can match the outer profile of the built-in end 21. The first mounting ring 41 can be formed on the side of the fixing part 4 facing the drain pump 3.

[0054] Reference Figure 1 and Figure 5 As shown, in some illustrative embodiments, a guide wall 42 is formed on the periphery of the first mounting ring 41. The guide wall 42 may gradually narrow in the direction from the drain pump 3 to the first mounting ring to guide the built-in end 21 into the first mounting ring 41. The guide wall 42 may, but is not limited to, be configured as a ring structure. For example, see reference... Figure 5 As shown, the guide wall 42 can be formed as a split structure that is disposed on both sides of the first mounting ring 41.

[0055] Figure 6 This is a perspective view of a locking component according to an illustrative embodiment of the present disclosure.

[0056] Reference Figure 1 and Figure 6 As shown, in some illustrative embodiments, the external end 22 can be configured as a sheet-like structure. The external end 22 can be attached to the outer wall 11 of the water receiving tray 1, which is opposite to the fixing part 4. The external end 22 may be provided with mounting holes 222. The external end 22 can be mounted to the outer wall 11 of the water receiving tray 1 using screws through the mounting holes 222.

[0057] Reference Figure 1 and Figure 6As shown, in some illustrative embodiments, the mating end 26 may include a first bent wall 262 and a second bent wall 263. The first bent wall 262 may extend from the upper end of the external end 22 (e.g., Figure 6 The upper end of the external end 22 shown is bent vertically toward the inside of the water receiving tray 1 and supported on the upper end of the outer wall 11 (as shown). Figure 1 (The upper end of the outer wall 11 shown). The second bent wall 263 can extend from the end of the first bent wall 262 parallel to the outer end 22.

[0058] Reference Figure 1 and Figure 6 As shown in some illustrative embodiments, the mating end 26 of the locking member 24 is formed with a second mounting ring 261 suitable for receiving the connecting end 25. The second mounting ring 261 may be formed on the second bent wall 263. The second bent wall 263 may be perpendicular to the connecting end 25, and the connecting end 25 may extend beyond the second bent wall 263. The orthographic projection of the portion of the connecting end 25 extending out of the second mounting ring 261 falls within the orthographic projection range of the first bent wall 262, that is, the connecting end 25 does not protrude beyond the first bent wall 262, so that the connecting end 25 will not interfere with other components of the water receiving tray 1, thereby improving the safety of the flexible member 23. The orthographic projection can be characterized as the projection in the direction perpendicular to the first bent wall 262.

[0059] In some illustrative embodiments, the external end 22 has an engaging region 221. A support portion 112 matching the shape of the engaging region 221 is formed on the outer wall 11 of the water receiving tray 1. The support portion 112 is configured to support the external end 22.

[0060] Reference Figure 6 As shown, in some illustrative embodiments, the engaging region 221 can be configured as any protruding structure extending beyond other parts of the external end 22. For example, the engaging region 221 can be a fan-shaped structure or a semi-circular structure, etc.

[0061] Reference Figure 1 and Figure 6 As shown in some illustrative embodiments, the support portion 112 may include a first baffle 113 located below the engaging area 221, and a second baffle 111 connected to the first baffle 113 and extending upward. By providing the support portion 112, when installing the locking member 24, the operator can first place the engaging area 221 on the support portion 112. The support portion 112 can serve to position and support the external end 22. When the engaging area 221 of the locking member 24 engages with the support portion 112, the locking member 24 is prevented from shaking, making it easier for the operator to further install the locking member 24 onto the outer wall 11 of the water receiving tray 1 by means of screw connection, thereby improving installation accuracy and installation stability.

[0062] In some illustrative embodiments, at least one of the connecting end 25 and the built-in end 21 is formed with a base 27, an insert block 28, and a protruding block 29. The base 27 may be disposed on the outside of the fixing block 210. The insert block 28 may protrude from the end face of the base 27 away from the fixing block 210 and is configured to pass through the second mounting ring 261 or the first mounting ring 41. The protruding block 29 may be disposed on the side of the insert block 28. The first mounting ring 41 or the second mounting ring 261 is constrained between the protruding block 29 and the end face of the base 27.

[0063] Reference Figure 1 and Figure 3 As shown, the base 27 can extend radially from the outside of the fixing block 210 and abut against the side of the first mounting ring 41 or the second mounting ring 261 near the drain pump 3. The protruding block 29 can abut against the side of the first mounting ring 41 or the second mounting ring 261 away from the drain pump 3. Figure 3 As shown, two symmetrically arranged protruding blocks 29 can be provided on the embedded block 28. Further, as... Figure 3 As shown, the protruding block 29 can extend upwards at an angle toward the drain pump 3. Furthermore, the volume of the protruding block 29 can be small, and when the flexible member 23 is pulled, the protruding block 29 can deform, causing the embedded block 28 to disengage from the first mounting ring 41 or the second mounting ring 261.

[0064] In some illustrative embodiments, a spring may be connected below the protruding block 29. As the protruding block 29 passes through the first mounting ring 41 or the second mounting ring 261 along with the insert block 28, the protruding block 29 may elastically descend. After passing through the first mounting ring 41 or the second mounting ring 261, the protruding block 29 may elastically rise to abut against the first mounting ring 41 or the second mounting ring 261.

[0065] In some illustrative embodiments, the connecting end 25 may be provided with a base 27, an insert block 28, and a protruding block 29, while the built-in end 21 may not have a base 27, an insert block 28, and a protruding block 29. Since the external end 22 is located on the outer wall 11 of the water receiving tray 1, the external end 22 can prevent the connecting end 25 from moving towards the external end 22. Therefore, the first mounting ring 41 only needs to accommodate the built-in end 21; that is, the first mounting ring 41 only needs to form a placement space that matches the contour shape of the built-in end 21. For example, the first mounting ring 41 may be configured as a groove structure. In such an embodiment, when the flexible member 23 is pulled, the deformation of the protruding block 29 may not be sufficient to disengage the insert block 28 from the second mounting ring 261. Instead, the protruding block 29 and the insert block 28 may be disengaged from the second mounting ring 261 by pressing. In such an embodiment, when the external end 22 disengages from the outer wall 11 of the water receiving tray 1, the built-in end 21 can easily disengage from the first mounting ring 41.

[0066] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some illustrative embodiments, the drain pump 3 may include a housing 31 and a rotating part 32. A water inlet 311 is formed at the bottom of the housing 31. The water inlet 311 is spaced apart from the bottom surface 12 of the water receiving tray 1. The rotating part 32 may be disposed inside the housing 31. By rotating the rotating part 32, liquid enters the drain pump 3 through the water inlet 311 and is discharged from the drain channel 33 of the drain pump 3.

[0067] Figure 7 This is a cross-sectional view of a drainage pump according to an illustrative embodiment of the present disclosure.

[0068] Reference Figure 3 , Figure 4 and Figure 7 As shown, a motor 34 may be mounted on the upper part of the housing 31. The motor 34 is connected to the rotating part 32 via a transmission rod 35. The rotating part 32 may be configured as a turbine blade or other components suitable for driving fluid movement by rotation.

[0069] In some illustrative embodiments, a through hole 312 is formed in the middle of the housing 31. Liquid in the water receiving tray 1 flows into or out of the drain pump 3 through the through hole 312.

[0070] Reference Figure 3 , Figure 4 and Figure 7 As shown, the through hole 312 can be provided on the outer periphery of the transmission rod 35, that is, between the motor 34 and the rotating part 32. Specifically, the highest point of the through hole 312 can be provided near the lower part of the motor 34, and the lowest point of the through hole 312 can be provided near the upper part of the rotating part 32.

[0071] In this embodiment, by providing a through hole 312, liquid can enter the drainage pump 3 not only through the inlet hole 311 but also through the through hole 312. This increases the liquid flow rate into the drainage pump 3. Furthermore, when the drainage pump 3 stops draining, excess liquid in the drainage pump 3 and the drainage channel 33 can flow out through the through hole 312, preventing the transmission rod 35 from being submerged for extended periods and thus extending the service life of the drainage pump 3.

[0072] Furthermore, in some illustrative embodiments, a foot pad 36 may be provided at the bottom of the drain pump 3. The foot pad 36 may also be made of a flexible material, thereby further preventing the drain pump 3 from contacting the base plate 13 of the water tray 1 and generating noise.

[0073] Figure 8 This is a cross-sectional view of a humidification device according to an illustrative embodiment of the present disclosure. Figure 9This is a diagram showing the positional relationship between the humidifying water tray and the water receiving tray according to an illustrative embodiment of the present disclosure.

[0074] This disclosure also provides a humidification device 5. The humidification device 5 may include the aforementioned drainage device, humidification water tray 6, and humidification section. The humidification water tray 6 may be located above the drainage device. A portion of the liquid in the humidification water tray 6 is discharged to the drainage device. The humidification section is configured to draw in the liquid from the humidification water tray 6 and humidify the outside air.

[0075] Furthermore, the humidifying water tray 6 can be used to store liquid for humidifying the air. Besides entering the humidifying section, some of the liquid accumulated in the humidifying water tray 6 is discharged to the drainage device and then drained. The liquid stored in the humidifying water tray 6 can be water or other liquids that have a humidifying effect, such as liquids containing hypochlorous acid. Furthermore, liquid can be supplied to the humidifying water tray 6 via a water supply unit (not shown in the figure) located above or to the side of the humidifying water tray 6. The water supply unit and the humidifying water tray 6 can be connected via a water supply pipe (e.g., from a tap water pipe).

[0076] The humidifying unit (not shown) may include a water-absorbing section, a crushing wall, and a driving section. The driving section can be used to drive the water-absorbing section to rotate. When the water-absorbing section rotates, liquid near the water-absorbing section is drawn into the hollow space of the water-absorbing section. After being broken up inside the water-absorbing section, the liquid flies from the outlet of the water-absorbing section to the crushing wall, where it is further broken up, thereby mixing with the gas flowing through the humidifying device 5, and together they are blown out from the air outlet of the humidifying device 5.

[0077] Specifically, the lower end of the water-absorbing part can be located in the humidifying water tray 6. The water-absorbing part can draw liquid from the humidifying water tray 6 by rotating. The water-absorbing part can be a hollow rotating body composed of an upper part and a lower part. The upper part can be provided with a top opening, and the lower part can be provided with a water inlet. The upper and lower parts can be integrally formed. The diameter of the upper part is larger than the diameter of the lower part. The water-absorbing part can rotate under the drive of the drive unit, thereby drawing the liquid in the humidifying water tray 6 upward. That is, after the liquid in the humidifying water tray 6 enters the water-absorbing part through the water inlet, it flows from the lower part of the water-absorbing part to the upper part of the water-absorbing part. The lower end of the water-absorbing part being located in the humidifying water tray 6 can be characterized as the lower end of the water-absorbing part being immersed in the liquid when a certain amount of liquid is stored in the humidifying water tray 6. It should be noted that the lower end of the water-absorbing part refers to the section extending upward from the bottom of the water-absorbing part.

[0078] In some illustrative embodiments, the humidification device 5 may also be equipped with various functional units designed according to different product positioning, such as air dehumidification unit, air guiding unit, heat exchange unit, filtration unit, and sterilization unit. Detailed descriptions of other functional units are omitted in this utility model.

[0079] In some illustrative embodiments, the humidifying water tray 6 may include a main humidifying water tray 61 and an auxiliary humidifying water tray 62. The water receiving tray 1 includes a first water receiving tray 16 and a second water receiving tray 17 that are connected to each other. A partition plate 18 is provided between the first water receiving tray 16 and the second water receiving tray 17. Liquid in the main humidifying water tray 61 is discharged to the first water receiving tray 16, and liquid in the auxiliary humidifying water tray 62 is discharged to the second water receiving tray 17.

[0080] Furthermore, the main humidifying water tray 61 is used to store a larger amount of liquid, while the auxiliary humidifying water tray 62 is used to store a smaller amount of liquid. The first water receiving tray 16 receives more liquid than the second water receiving tray 17. The drainage device can be located on one side of the first water receiving tray 16. A partition plate 18 is provided between the first water receiving tray 16 and the second water receiving tray 17. The partition plate 18 has a connecting port 19 on the side opposite to the drainage device. Liquid can reach the first water receiving tray 16 from the second water receiving tray 17 through the connecting port 19. When the water receiving tray 17 is tilted towards the drainage device, the liquid will preferentially flow to the drainage device. When the water receiving tray is tilted towards the other side of the drainage device, the water in the first water receiving tray is blocked by the partition plate 18 and will not flow into the second water receiving tray, thereby preventing the liquid in the second water receiving tray 17 from exceeding the predetermined water level line.

[0081] The installation process of the drainage device will be described in detail below.

[0082] First, the built-in end 21 can be oriented towards the first mounting ring 41. Since the fixing part 4 is provided with a guide wall 42, after the built-in end 21 contacts the guide wall 42, it can be smoothly inserted into the first mounting ring 41 under the guidance of the guide wall 42. Thus, even in a small operating space, the operator can quickly insert the built-in end 21 into the first mounting ring 41. Furthermore, when the built-in end 21 is inserted into the first mounting ring 41, when the insert block 28 and the protrusion block 29 provided on the insert block 28 contact the first mounting ring 41, the protrusion block 29 will undergo slight deformation due to its flexibility. And because the protrusion block 29 is small in size, that is, the contact area between the protrusion block 29 and the first mounting ring 41 is small, the friction between the built-in end 21 and the first mounting ring 41 can be reduced, so that the protrusion block 29 and the insert block 28 can pass through the first mounting ring 41, so that the base 27 abuts against the first mounting ring 41, thereby realizing the insertion of the built-in end 21 into the first mounting ring 41.

[0083] After the built-in end 21 is inserted into the first mounting ring 41, the connecting end 25 is located on the outer wall 11 of the water receiving tray 1, which is opposite to the fixing part 4. To further secure the drain pump 3, the connecting end 25 can be inserted into the second mounting ring 261 based on the same principle. And since the connecting end 25 does not protrude from the first bent wall 262, the connecting end 25 will not interfere with other components of the water receiving tray 1.

[0084] Furthermore, to ensure that the mating end 25 can be accurately aligned with the second mounting ring 261, a support portion 112 can be provided on the outer wall 11 of the water receiving tray 1. When the engaging area 221 of the locking member 24 engages with the support portion 112, the support portion 112 can position and support the external end 22, thereby allowing the mating end 25 to be accurately aligned with the second mounting ring 261.

[0085] In some illustrative embodiments, the connecting end 25 can be connected to the second mounting ring 261 first, and then the built-in end 21 can be connected to the first mounting ring 41. In this way, connecting the connecting end 25 to the second mounting ring 261 first can increase the operator's grip space, thereby further improving the ease of installation.

[0086] Furthermore, the locking component 24 is installed flush against the outer wall 11 of the water receiving tray 1. Installers can secure the locking component 24 with screws from the side wall of the water receiving tray 1, i.e., in the lateral direction of the water receiving tray 1, to lock the drain pump 3. At this time, the drain pump 3 is installed inside the water receiving tray 1 by the connecting part 2, and a certain distance is formed between the drain pump 3 and the bottom surface 12 of the water receiving tray 1. This ensures sufficient installation space while improving the installation accuracy of the drain pump 3.

[0087] In some illustrative embodiments, when disassembling the drainage device, the locking member 24 can be separated from the outer wall 11 of the water receiving tray 1 first, and then the embedded block 28 and the protruding block 29 can be disassembled from the first mounting ring 41 by dragging the connecting part 2, thereby disassembling the drainage device.
