[0040] Although the present invention is susceptible of being embodied in different forms, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to that described herein.

[0041] Thus, a feature indicated in this specification is intended to illustrate one of the features of one embodiment of the present invention, rather than to imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations. Thus, unless otherwise noted, the described combinations are not intended to be limiting.

[0042] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0043] See also Figures 1 to 6 An air purifier humidifier provided in one embodiment of the present invention includes a housing 1 , an air outlet component 2 , a filter 4 , a humidifying component 5 , a movable component 9 and a water tank 14 .

[0044] The housing 1 is provided with an air inlet 112, an air outlet 111, and a water return hole 31. The air outlet assembly 2 is disposed within the housing 1, driving air into the housing 1 through the air inlet 112 and out through the air outlet 111. The filter element 4 is disposed within the housing 1. The humidification assembly 5 includes a humidifier 51, which is disposed within the housing 1, downstream of the filter element 4 in the direction of air flow from the air inlet 112 to the air outlet.

[0045] The movable assembly 9 is movably connected to the housing 1. When the movable assembly 9 is in the first position, the water return hole 31 is opened, and when it is in the second position, the water return hole 31 is closed. The water tank 14 is detachably connected to the housing 1 and forms a linkage with the movable assembly 9. When the water tank 14 is installed on the housing 1, the movable assembly 9 is moved to the first position. When the water tank 14 is removed from the housing 1, the movable assembly 9 is moved to the second position.

[0046] Among them, the humidifying component 5 also includes a water pump 52. When the water tank 14 is installed in the shell 1, the water pump 52 transports the water in the water tank 14 to the shell 1 and sprays it toward the humidifying component 51. The water in the shell 1 can flow back to the water tank 14 through the return hole 31.

[0047] With the above structural design, when the water tank 14 is mounted on the housing 1, the movable assembly 9 is moved to the first position, and the water tank 14 drives the movable assembly 9 to move to the first position and open the water return hole 31. The water pump 52 transports the water in the water tank 14 into the housing 1 and sprays the water toward the humidifying element 51 to wet it.

[0048] Air is driven by the air outlet assembly 2 into the housing 1 through the air inlet 112 and out through the air outlet 111. In this embodiment, the air outlet assembly 2 includes a wind wheel and a motor that drives the wind wheel. The filter element 4 disposed within the housing 1 filters the air, while the humidifier 51 humidifies the air, increasing its humidity. Residual water within the housing 1 flows back through the water return hole 31 to the water tank 14, enabling water recovery.

[0049] When the water tank 14 is removed from the housing 1, the water tank 14 links the movable assembly 9 to the second position and closes the water return hole 31. This prevents excess water in the housing 1 from flowing out through the water return hole 31 and causing a short circuit in the circuit components inside the air purifier.

[0050] Since the movable component 9 is linked with the water tank 14, the accuracy of the opening or closing of the return hole 31 is ensured, which not only ensures that the return hole 31 can be correctly opened when the air purifier humidifier is in working state, but also ensures that the return hole 31 can be correctly closed when the water tank 14 is disassembled for water filling.

[0051] It should be noted that if the return water hole 31 is opened or closed by a separately acting component such as a solenoid valve, since the solenoid valve is difficult to ensure a high degree of working stability, the solenoid valve may still keep the return water hole 31 open when the water tank 14 is removed from the shell 1, which will cause the water in the shell 1 to overflow and cause a short circuit in the circuit components.

[0052] The shell 1 is divided into an air outlet chamber 11, a ventilation chamber 12 and a water storage chamber 13 from top to bottom. The air outlet 111 is provided at the top of the air outlet chamber 11, the air inlet 112 is provided on the side wall of the ventilation chamber 12, and a window 131 is provided on the side wall of the water storage chamber 13. The air purifier humidifier also includes a partition 3, which is provided between the ventilation chamber 12 and the water storage chamber 13, and a return water hole 31 is provided on the partition 3. The air outlet assembly 2 is provided in the air outlet chamber 11. The filter element 4 and the humidifying element 51 are provided in the ventilation chamber 12. The movable assembly 9 is provided in the water storage chamber 13, and the water tank 14 can enter and exit the ventilation chamber 12 through the window 131.

[0053] Main references Figure 2 and Figure 4, the upper end of the movable component 9 is hinged to the shell 1, and the movable component 9 and the shell 1 are provided with a matching snap-fit ​​structure. A water inlet 141 is provided on the water tank 14, and an unlocking portion 142 and a pushing portion 143 are provided on both sides of the water inlet 141. When the water tank 14 is installed on the shell 1, the unlocking portion 142 unlocks the snap-fit ​​structure to allow the movable component 9 to rotate to the first position. When the water tank 14 is removed from the shell 1, the pushing portion 143 pushes the movable component 9 to rotate to the second position, and the movable component 9 and the shell 1 form a snap-fit ​​fit, and the movable component 9 is fixed in the second position through the snap-fit ​​fit, ensuring that the movable component 9 can stably close the return water hole 31. In this embodiment, the first position is a vertical position, and the second position is a horizontal position. When the unlocking portion 142 unlocks the snap-fit ​​structure, the movable component 9 can rotate to the first position under the action of gravity.

[0054] See also Figure 5 and Figure 6 The movable assembly 9 includes a valve 91 and an articulated arm 92. The valve 91 is arranged in the housing 1 so as to float up and down. When the valve 91 floats upward, the return water hole 31 is opened, and when the valve 91 floats downward, the return water hole 31 is closed.

[0055] The valve 91 includes a valve core 911, a base 912, a rod 913, and a second elastic member 914. The valve core 911 is positioned above the return hole 31. The base 912 is positioned below the return hole 31. The rod 913 extends through the return hole 31 and connects the valve core 911 and the base 912. The second elastic member 914 is sleeved onto the rod 913 and drives the valve core 911 to float downward, closing the return hole 31. The upper end of the articulated arm 92 contacts the base 912, pushing the valve core 911 upward to open the return hole 31. The second elastic member 914 enables the valve core 911 to more tightly close the return hole 31, preventing water leakage. In this embodiment, the upper end of the second elastic member 914 abuts the partition 3, while the lower end abuts the base 912, driving the base 912 to cause the valve 91 to float downward. The second elastic member 914 may be a spring.

[0056] See also Figures 7 to 11 , and combined with Figure 2 and Figure 4An articulated arm 92 is disposed below the valve 91, with its upper end hinged to the housing 1. A matching snap-fit ​​structure is provided between the lower end of the articulated arm 92 and the housing 1. When the articulated arm 92 rotates to a first position, the upper end of the articulated arm 92 contacts and pushes the valve 91 upward, opening the return water hole 31. When the articulated arm 92 rotates to a second position, the upper end of the articulated arm 92 separates from the valve 91, causing the valve 91 to float downward, closing the return water hole 31. When the water tank 14 is installed in the water storage chamber 13, the articulated arm 92 extends into the water tank 14 through the water filling port 141. When the water tank 14 is removed from the housing 1, that is, when the water tank 14 is pulled out of the water storage chamber 13 through the window 131, the pushing portion 143 can push the articulated arm 92 to rotate to the second position. At this time, the upper end of the articulated arm 92 is out of contact with the valve 91, and the valve 91 floats downward to close the return water hole 31. The lower end of the articulated arm 92 is connected to the housing 1. When the water tank 14 is pulled out of the water storage chamber 13 and the water is filled, and then inserted into the water storage chamber 13, the unlocking portion 142 unlocks the locking structure, so that the articulated arm 92 is released from the second position and rotates to the first position under the action of its own gravity, so that the upper end of the articulated arm 92 can push the valve 91 upward to open the return water hole 31.

[0057] The movable assembly 9 also includes a locking block 93 and a first elastic member 94. The locking block 93 is movably connected to the lower end of the hinged arm 92. The clamping structure includes a first hook 931 provided on the locking block 93 and a second hook 15 provided on the housing 1. The first elastic member 94 acts on the locking block 93. When the water tank 14 is installed on the housing 1, the unlocking portion 142 enables the locking block 93 to overcome the elastic force of the first elastic member 94 and unlock the first hook 931 and the second hook 15. When the water tank 14 is removed from the housing 1, the first elastic member 94 drives the locking block 93 to move and causes the first hook 931 to be clamped to the second hook 15. The first elastic member 94 can be a spring.

[0058] The pushing portion 143 includes an inclined plate arranged in an inclined manner, and the inclined plate facilitates pushing the hinge arm 92 to rotate from the first position to the second position.

[0059] See also Figure 3 and Figure 8 A guide rib 132 is provided in the water storage chamber 13, and a guide groove 144 is provided on the water tank 14. The guide rib 132 and the guide groove 144 guide the position of the water tank 14 entering the water storage chamber 13 through the window 131, ensuring that the water tank 14 can be installed in the correct position, so that the movable assembly 9 can be accurately linked to open or close the water return hole 31.

[0060] See also Figure 11 , and combined with Figure 2 and Figure 4The humidifying component 5 also includes a water inlet pipe 54 and a water inlet hose (not shown). The water inlet pipe 54 is fixed to the movable component 9 and extends in the same direction as the movable component 9. One end of the water inlet hose is connected to the water inlet pipe 54, and the other end faces the humidifying component 51. The water pump 52 transports the water in the water tank 14 to the shell 1 through the water inlet pipe 54 and the water inlet hose, and sprays it toward the humidifying component 51. The water inlet pipe 54 can rotate synchronously with the movable component 9. When the movable component 9 rotates to the first position, the water inlet pipe 54 rotates synchronously to the first position and is inserted into the water tank 14 to collect water. When the movable component 9 rotates to the second position, the water inlet pipe 54 rotates synchronously to the second position and moves above the water tank 14. Since the second position is horizontal, it can prevent the water in the water inlet pipe 54 from dripping down into the water storage chamber 13 and causing a short circuit in the electronic components. In this embodiment, the water inlet pipe 54 is fixed to the articulated arm 92 and rotates synchronously with the articulated arm 92.

[0061] See also Figure 2 and Figure 4 The humidifying assembly 5 also includes a diffuser plate 53 and a water spray pipe 55. The diffuser plate 53 is annular and has a flow groove 531 with an open top. The bottom of the flow groove 531 has water spray ports 532. Multiple water spray ports 532 are provided and spaced circumferentially. The diffuser plate 53 is located at the upper end of the humidifying element 51. The water spray pipe 55 is located above the flow groove 531. The water pump 52 pumps water from the water storage chamber 13 to the ventilation chamber 12, then fills the flow groove 531 with water. The water then flows through the multiple water spray ports 532 to the humidifying element 51 to wet it.

[0062] See also Figures 12 to 15 The filter element 4 is arranged in an annular shape. The humidifier element 51 is arranged in an annular shape and is located inside the filter element 4. The air purifier humidifier also includes a sterilization assembly 6, which includes a sterilization lamp 61 and a light shield 62. The sterilization lamp 61 is located in the ventilation cavity 12 and is located inside the humidifier element 51. The light shield 62 is located in the ventilation cavity 12 and covers the sterilization lamp 61. The light shield 62 has multiple ventilation openings 621 on its peripheral side.

[0063] The filter element 4, located within the ventilation chamber 12, filters the air and includes, but is not limited to, a filter mesh. The water pump 52 within the humidifier assembly 5 pumps water from the water tank 14 into the ventilation chamber 12 and sprays it toward the humidifier 51, causing it to humidify the air and increase its humidity. The humidifier 51 includes, but is not limited to, antibacterial, absorbent nonwoven fabric. Residual water within the water storage chamber 13 flows back into the water tank 14 through the return hole 31, thus recycling the water.

[0064] Multiple vents 621 are provided on the peripheral side of the light shield 62, allowing air to flow within the light shield 62 and the ventilation cavity 12. The sterilizing lamp 61 sterilizes and disinfects the air, enhancing the air purification effect. Furthermore, the light shield 62 prevents a large amount of light from directly impinging on the humidifier 51, which could cause it to age and fail. The small amount of light that passes through the vents 621 and reaches the humidifier 51 can at least partially sterilize and disinfect the humidifier 51. In this embodiment, the sterilizing lamp 61 is a UV lamp, and the light shield 62 is made of a UV-resistant material, such as, but not limited to, ASA plastic.

[0065] The partition 3 is also provided with a wire hole 32. The sterilization component 6 also includes a mounting seat 63, and a wire passage 631 is provided in the mounting seat 63. The mounting seat 63 is provided in the ventilation cavity 12 and is connected above the partition 3. The outlet of the wire passage 631 is connected to the wire hole 32, and the inlet of the wire passage 631 is higher than the return hole 31. The sterilization lamp 61 is supported above the mounting seat 63, and the electrical connection line of the sterilization lamp 61 passes through the wire passage 631 from the entrance of the wire passage 631, and passes out from the outlet of the wire passage 631 and the wire hole 32. By setting the entrance of the wire passage 631 at a position higher than the return hole 31, the electrical connection line of the sterilization lamp 61 prevents water from flowing out from the entrance of the wire passage 631, flowing along the electrical connection line into other electronic components inside the air purifier humidifier and causing a short circuit. It should be noted that if the valve 91 does not close the water return hole 31 when the water tank 14 is drawn out of the water storage chamber 13, the water flowing out of the water return hole 31 will also flow into other electronic components inside the air purifier humidifier and cause a short circuit.

[0066] See also Figure 2 and Figure 4 The electronic components inside the air purifier humidifier also include a control board 71 arranged at the top of the air outlet chamber 11, a sterilization lamp adapter board 72 arranged near the side wall of the shell 1, and a power supply 73 arranged at the bottom of the ventilation chamber 12. In this embodiment, the sterilization lamp adapter board 72 is arranged near the side wall of the ventilation chamber 12 and the side wall of the water storage chamber 13. The power supply 73 is electrically connected to the control board 71 for power supply. The electrical connection line of the sterilization lamp 61 passes through the wire hole 32 and is connected to the sterilization lamp adapter board 72. The sterilization lamp adapter board 72 is electrically connected to the control board 71. If the inlet of the threading channel 631 is not higher than the position of the return water hole 31, water may flow out from the inlet of the threading channel 631 and flow along the electrical connection line of the sterilization lamp 61 to the sterilization lamp adapter board 72, causing a short circuit.

[0067] See also Figures 14 to 16 A water passage 632 is further provided in the mounting seat 63, and the water return hole 31 is provided on the inner side of the water passage 632. The residual water in the ventilation cavity 12 enters the water passage 632 and flows back from the water return hole 31 to the water tank 14, thereby recycling water and effectively improving water utilization.

[0068] See also Figures 13 to 16 The light shield 62 includes an outer light-blocking strip 622 and an inner light-blocking strip 623. The outer light-blocking strips 622 are spaced apart circumferentially. The inner light-blocking strips 623 are spaced apart circumferentially, and the inner light-blocking strips 623 are disposed inside the outer light-blocking strips 622 and are disposed one-to-one between adjacent outer light-blocking strips 622. A vent 621 is formed between the outer light-blocking strips 622 and the inner light-blocking strips 623.

[0069] The light shield 62 is further positioned outside the mounting base 63 and connected to the partition 3. The connection between the partition 3 and the light shield 62 provides a more stable mounting for the light shield 62. A water hole 624 is also provided on the side surface of the light shield 62. The water hole 624 connects to the water return hole 31 via a water passage 632. Residual water in the ventilation chamber 12 flows through the water hole 624 into the water passage 632, and then flows back from the water return hole 31 into the water tank 14.

[0070] The light shield 62 has a step surface 625, and the sterilization component 6 also includes a first flexible sleeve 626 and a second flexible sleeve 627. The first flexible sleeve 626 and the second flexible sleeve 627 are both arranged in the light shield 62. The first flexible sleeve 626 is sleeved on the upper end of the sterilization lamp 61. The second flexible sleeve 627 is sleeved on the lower end of the sterilization lamp 61 and is clamped between the step surface 625 and the top of the mounting seat 63. The first flexible sleeve 626 and the second flexible sleeve 627 play a role in protecting and fixing the sterilization lamp 61, and also play a role in waterproofing. The first flexible sleeve 626 and the second flexible sleeve 627 can be rubber sleeves or silicone sleeves. The first flexible sleeve 626 is inserted into the top of the light shield 62 for fixation. The second flexible sleeve 627 is clamped between the step surface 625 and the top of the mounting seat 63 for fixation.

[0071] The partition 3 is recessed to form a water reservoir 33 and has a support surface 34 located outside the reservoir and higher than the bottom of the reservoir. The lower end of the humidifier 51 extends into the reservoir and is supported by the bottom of the reservoir. The filter element 4 is located outside the reservoir, with its lower end supported by the support surface 34. Any residual water in the ventilation chamber 12 is stored in the reservoir, preventing the filter element 4 from soaking and degrading the filtration effect.
