[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] like Figures 1 to 5 As shown, the upper cover assembly 10 of the embodiment of the present invention includes a cover plate 1 and a blocking member 2, which is movably connected to the cover plate 1. The cover plate 1 is provided with a water supply hole 111, and the blocking member 2 has a blocking portion 21. The blocking portion 21 blocks the water supply hole 111 when the tilt angle of the cover plate 1 is greater than or equal to a preset angle, and opens the water supply hole 111 when the tilt angle of the cover plate 1 is less than the preset angle. Figure 6 As shown, the upper cover assembly 10 is used to cover the opening 201 of the water tank 20.

[0038] It can be understood that when the upper cover assembly 10 is installed on the opening 201 of the water tank 20, when the water tank 20 tilts, the upper cover assembly 10 will also tilt with the water tank 20. At this time, if the water filling hole 111 is in the open state, the water in the water tank 20 will flow out through the water filling hole 111; if the water filling hole 111 is in the closed state, the water in the water tank 20 will not flow out through the water filling hole 111.

[0039] The upper cover assembly 10 of the embodiment of the present invention is provided with a blocking member 2 movably connected to the cover plate 1, so that when the water tank 20 with the upper cover assembly 10 is tilted, the cover plate 1 will be tilted at an angle greater than or equal to a preset angle. At this time, the blocking portion 21 of the blocking member 2 is used to block the water filling hole 111, so that the water filling hole 111 is in a closed state, preventing the water in the water tank 20 from flowing out through the water filling hole 111. When the water tank 20 with the upper cover assembly 10 is in normal use, the tilt angle of the cover plate 1 will be less than the preset angle. At this time, the blocking portion 21 is separated from the water filling hole 111, so that the water filling hole 111 is in an open state, and water can be added to the water tank 20 through the water filling hole 111.

[0040] Thus, when the water tank 20 falls over, the water in the water tank 20 can be prevented from flowing out through the water filling hole 111, thereby improving the user experience. In addition, when the water temperature in the water tank 20 is high, the risk of the user being scalded by hot water can also be reduced.

[0041] Optionally, the preset angle is 70° to 90°.

[0042] That is to say, when the inclination angle of the cover plate 1 is greater than or equal to 70°~90°, it is judged that the water tank 20 has tilted, and at this time, the blocking portion 21 blocks the water filling hole 111; when the inclination angle of the cover plate 1 is less than 70°~90°, it is judged that the water tank 20 has not tilted, and at this time, the blocking portion 21 leaves the water filling hole 111.

[0043] In some embodiments, as Figure 1 and Figure 3 As shown, there are multiple water adding holes 111 and multiple blocking members 2 , and each blocking member 2 is provided corresponding to at least one water adding hole 111 .

[0044] For example, the number of the water adding holes 111 and the number of the blocking members 2 are both four, and each blocking member 2 is provided corresponding to one water adding hole 111 .

[0045] By providing a plurality of blocking members 2 , the blocking members 2 may be provided only at positions corresponding to the water supply holes 111 , thereby saving material costs of the blocking members 2 and reducing the cost of the upper cover assembly 10 .

[0046] In other embodiments, the number of water supply holes 111 can be set to multiple, and the number of blocking members 2 can be set to only one, and the blocking member 2 has multiple blocking portions 21, each blocking portion 21 corresponding to a water supply hole 111. In this case, multiple water supply holes 111 are blocked by the same blocking member 2.

[0047] In some embodiments, the blocking member 2 is movably connected to the cover plate 1 along the extending direction of the water filling hole 111. The extending direction of the water filling hole 111 may be consistent with the height direction of the water tank 20.

[0048] In order to make the technical solution of the present invention easier to understand, the following takes the extension direction of the water adding hole 111 and the vertical direction as an example to further describe the technical solution of the present invention. Figures 1 to 7 shown.

[0049] For example, the blocking member 2 is movably connected to the cover plate 1 in the vertical direction. The blocking member 2 is disposed on the underside of the cover plate 1 and corresponds to the water supply hole 111. When the cover plate 1 is tilted at an angle greater than or equal to a predetermined angle, the blocking member 2 moves upward, and the blocking portion 21 abuts upward against the cover plate 1, thereby blocking the water supply hole 111. When the cover plate 1 is tilted at an angle less than the predetermined angle, the blocking member 2 moves downward, and the blocking portion 21 moves away from the cover plate 1, at which point the water supply hole 111 is open.

[0050] By movably connecting the blocking member 2 to the cover plate 1 along the extension direction of the water supply hole 111, the blocking member 2 can be moved along the extension direction of the water supply hole 111 to block or remove the water supply hole 111. The connection structure between the blocking member 2 and the cover plate 1 is simple, facilitating the processing and manufacturing of the upper cover assembly 10.

[0051] Optionally, the blocking member 2 is provided at the bottom of the cover plate 1, the blocking portion 21 is provided at the top of the blocking member 2, and a pushing portion 22 is provided at the bottom of the blocking member 2. When the tilt angle of the cover plate 1 is greater than or equal to a preset angle, the pushing portion 22 is pushed by the water in the water tank 20, causing the blocking member 2 to move toward the cover plate 1.

[0052] For example, when the inclination angle of the cover plate 1 is greater than or equal to the preset angle, the water in the water tank 20 flows to the pushing portion 22 and pushes the blocking member 2 toward the cover plate 1 under the action of water pressure, so that the blocking portion 21 blocks the water filling hole 111.

[0053] It is understood that when the water tank 20 is tilted, the water in the water tank 20 will move toward the water filling hole 111. By providing the push portion 22 on the blocking member 2, the water in the water tank 20 can be used to push the blocking member 2 to move, thereby avoiding the need for other structures on the blocking member 2 to push the blocking member 2 to move. This helps to simplify the structure of the blocking member 2 and further reduce the cost of the upper cover assembly 10.

[0054] Alternatively, as Figures 3 to 5 As shown, the blocking member 2 includes a blocking piece, the top surface of the blocking piece forms a blocking portion 21 , and the bottom surface of the blocking piece forms a pushing portion 22 .

[0055] For example, the upper surface of the blocking piece forms the blocking portion 21 , and the lower surface of the blocking piece forms the pushing portion 22 .

[0056] By configuring the blocking member 2 to include a blocking piece, with the top and bottom surfaces of the blocking piece forming the blocking portion 21 and the pushing portion 22 respectively, the structure of the blocking member 2 is simplified, and the cost of the upper cover assembly 10 is further reduced.

[0057] Alternatively, as Figure 2 、 Figure 4 and Figure 5As shown, the cover plate 1 includes a plate body 11 and a connecting portion 12. The connecting portion 12 is arranged at the bottom of the plate body 11 and is spaced apart from the plate body 11. A water supply hole 111 is provided on the plate body 11. The blocking member 2 is connected to the connecting portion 12. The blocking portion 21 is provided between the plate body 11 and the connecting portion 12.

[0058] For example, the connecting portion 12 is provided on the lower side of the plate body 11 , and the blocking portion 21 is provided between the plate body 11 and the connecting portion 12 in the vertical direction. The blocking portion 21 can move up and down between the plate body 11 and the connecting portion 12 .

[0059] By configuring the cover plate 1 to include a plate body 11 and a connecting portion 12 , arranging the water supply hole 111 on the plate body 11 , and connecting the blocking member 2 to the connecting portion 12 , the design and manufacture of the cover plate 1 are facilitated.

[0060] Optionally, the connecting portion 12 is a connecting piece.

[0061] Optionally, the connecting portion 12 and the plate body 11 are integrally formed.

[0062] For example, the connecting portion 12 and the plate body 11 are integrally injection molded.

[0063] Alternatively, as Figures 2 to 5 As shown, the connecting portion 12 is provided with a slot 121 , and the bottom of the blocking member 2 is provided with a connecting column 23 , which is connected to the slot 121 .

[0064] The slot 121 has an opening facing the outside of the plate 11 , so that the connecting post 23 can be inserted into the slot 121 from the outside to the inside.

[0065] By connecting the connecting column 23 with the card slot 121, the connection structure between the blocking member 2 and the connecting portion 12 is simplified, which is not only convenient for processing and manufacturing, but also convenient for connecting the blocking member 2 and the cover plate 1, which is conducive to further reducing the cost of the upper cover assembly 10.

[0066] Alternatively, as Figures 3 to 5 As shown, a limiting portion 24 is provided at the bottom of the connecting post 23 . The limiting portion 24 is disposed on a side of the connecting portion 12 away from the plate body 11 . The limiting portion 24 is used to abut against the connecting portion 12 .

[0067] For example, the limiting portion 24 is disposed at the lower side of the connecting portion 12 , and the limiting portion 24 is configured to abut against the connecting portion 12 upward.

[0068] By providing the limiting portion 24 , the connection column 23 can be prevented from falling out of the slot 121 , thereby improving the connection reliability between the blocking member 2 and the cover plate 1 , and improving the reliability of the upper cover assembly 10 .

[0069] Alternatively, as Figures 3 to 5As shown, the upper cover assembly 10 further includes a seal 3 , which is disposed on the blocking portion 21 , and is configured to seal with the cover plate 1 .

[0070] For example, Figure 3 As shown, the sealing member 3 is annular, and an annular sealing groove 25 is provided on the sealing portion 21 , and the sealing member 3 is installed in the sealing groove 25 .

[0071] By arranging a seal 3 on the blocking part 21, when the blocking part 21 blocks the water adding hole 111, the seal 3 can improve the sealing performance of the blocking part 21 on the water adding hole 111, thereby more effectively preventing the water in the water tank 20 from flowing out through the water adding hole 111, further improving the user experience.

[0072] like Figure 6 and Figure 7 As shown, the humidifier 100 of the embodiment of the present invention includes a water tank 20 and an upper cover assembly 10. The top of the water tank 20 is provided with an opening 201. The upper cover assembly 10 is the upper cover assembly 10 described in any of the above embodiments, and the upper cover assembly 10 is covered on the opening 201.

[0073] The humidifier 100 of the present invention can prevent the water in the water tank 20 from flowing out through the water filling hole 111 when the water tank 20 falls over, thereby improving the user experience. In addition, when the water temperature in the water tank 20 is high, the risk of hot water scalding the user can be reduced.

[0074] like Figures 3 to 5 As shown, the upper cover assembly 10 includes a mist outlet 5, which is connected to the cover plate 1 and has a mist outlet 51. Figure 7 As shown, the humidifier 100 includes a mist guide pipe 40 , and the upper end of the mist guide pipe 40 is connected to the mist outlet member 5 .

[0075] Thus, the water mist in the mist guide pipe 40 can flow out through the mist outlet 51 of the mist outlet member 5 .

[0076] like Figure 3 As shown, the upper cover assembly 10 further includes a sealing ring 4 , which is arranged circumferentially around the cover plate 1 . The sealing ring 4 is clamped between the water tank 20 and the cover plate 1 to improve the sealing between the water tank 20 and the upper cover assembly 10 .

[0077] Optionally, the water tank 20 is snap-connected to the cover plate 1 .

[0078] For example, Figure 6 As shown, the cover plate 1 is provided with an upper cover buckle 13 , and the water tank 20 is provided with a snap-fitting hole 202 , and the upper cover buckle 13 is snap-fitted with the snap-fitting hole 202 .

[0079] The water tank 20 is snap-fitted to the cover plate 1 , making it easy to connect and disassemble the cover plate 1 and the water tank 20 .

[0080] Optionally, the humidifier 100 is a steam humidifier, and a heating element 30 is provided in the water tank 20 .

[0081] The cup heating element 30 in the water tank 20 is heated into steam and then flows into the mist guide pipe 40 . The water mist (steam) in the mist guide pipe 40 flows out through the mist outlet 51 of the mist outlet 5 .

[0082] In the humidifier 100 of the embodiment of the present invention, the mist outlet member 5 is installed on the cover plate 1, the sealing ring 4 is fixed to the cover plate 1, and the sealing member 3 is fixed to the blocking member 2. The blocking member 2 is connected to the slot 121 of the cover plate 1 through the connecting column 23, so that the blocking member 2 can move along the extension direction of the water filling hole 111, and the blocking member 2 is limited by the limiting portion 24. The heating element 30 is fixed to the bottom of the water tank 20, and the mist guide pipe 40 is fixed to the water tank 20 and sleeved on the heating element 30. The cover plate 1 is clamped with the clamping hole 202 of the water tank 20 through the upper cover buckle 13, and the water tank 20 and the cover plate 1 are sealed with the sealing ring 4.

[0083] When the water tank 20 is in a normal state, the blocking member 2 leaves the water filling hole 111 under the action of its own gravity, and the water filling hole 111 is in an open state (such as Figure 4 As shown in FIG1 , water can be added to the water tank 20 through the water filling hole 111. When the water tank 20 is tilted, the water in the water tank 20 acts on the pushing portion 22 of the blocking member 2, causing the blocking member 2 to move toward the cover plate 1, so that the blocking member 2 blocks the water filling hole 111 (as shown in FIG1 ). Figure 5 As shown), the water in the water tank 20 will not flow out from the water filling hole 111.

[0084] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments made by ordinary technicians in this field are all within the scope of protection of the present invention.
