[0002] In various air outlet devices, such as air conditioners, air purifiers, and humidifiers, the water filling structure is a crucial component. As people's demands for comfortable living environments continue to increase, the functions of air outlet devices are becoming increasingly diversified, with humidity regulation being a particularly significant requirement. In traditional air outlet devices, the water filling structure often requires removing the water tank and then adding water through the tank's inlet. However, this design makes the water filling process too complex, and the overall structure appears somewhat redundant. Summary of the Invention

[0004] In particular, a first aspect of this application provides a water filling structure for an air outlet device, including a housing, a nozzle, and a water filling channel formed between the housing and the nozzle. The housing is used to generate an airflow, and the nozzle is located upstream of the airflow in the housing and is used to emit an airflow. The nozzle is rotatably disposed on the upper part of the housing, and a gap is formed between the nozzle and the upper part of the housing, which forms the water filling channel.

[0005] Optionally, the gap is annular.

[0006] Optionally, it also includes a water filling cover plate, which is disposed on the upper part of the housing and surrounds the periphery of the nozzle, and the inner circumferential surface of the water filling cover plate and the bottom outer wall of the nozzle form the gap.

[0011] Optionally, it also includes a water tank, which is located below the outer end of the guide portion inside the housing.

[0012] Optionally, the inner wall of the water tank in the radial direction is connected to the outer end of the guide.

[0013] Optionally, the inner bottom surface of the water tank has a low point area, the height of which is lower than the height of any other inner bottom surface area of ​​the water tank.

[0014] Optionally, it also includes a drain pipe for connecting the low point area of ​​the water tank and the water tank.

[0015] Optionally, the inner bottom surface of the water filling cover is further formed with a base plate, and the bottom surface of the base plate is sealed to the outer side wall of the water tank in the radial direction.

[0016] Optionally, the top opening of the water tank further includes a filter structure, which is disposed inside the housing and located between the opening of the water tank and the outer end of the guide portion.

[0017] Optionally, the filter structure includes a filter screen support and a filter screen body connected to the filter screen support. The filter screen support is connected to the outer end of the guide portion, the filter screen body is disposed on the outer end of the filter screen support, and the opening of the water tank is located below the filter screen body.

[0018] Optionally, the outer periphery of the filter support has a hollowed-out mounting area formed on the upper and lower surfaces along the thickness direction, and the filter body is disposed on the mounting area.

[0019] Optionally, a first baffle is formed at the outer end of the filter support, the first baffle extending along the thickness direction of the filter support and higher than the upper surface of the filter body.

[0020] Optionally, the width of the opening of the water tank in the radial direction is greater than or equal to the width of the filter screen body, so as to accommodate the portion of the filter screen support corresponding to the filter screen body.

[0021] Optionally, a second baffle plate extends upward along the thickness direction from the inner end of the guide portion in the radial direction, and the bottom of the nozzle is sleeved on the second baffle plate.

[0022] Optionally, the height of the second shield is greater than the height of the outer periphery of the water filling cover.

[0023] A second aspect of this application provides a water filling structure for an air outlet device, including a housing, a nozzle, and a water filling channel formed between the housing and the nozzle. The housing is used to generate an airflow, and the nozzle is located upstream of the airflow in the housing and is used to emit the airflow. The nozzle is located on the upper part of the housing and is an annular nozzle extending away from the upper part of the housing. A gap is formed between the nozzle and the upper part of the housing, and the gap forms the water filling channel.

[0024] A third aspect of this application provides an air outlet device, including a water filling structure and a water tank.

The water filling structure is any of the water filling structures described above. The water tank is disposed inside the housing and is used to receive water added through the water filling channel.

[0026] The water filling mechanism of the air outlet device of this application has a nozzle rotatably mounted on the upper part of the housing, and the gap formed between the nozzle and the upper part of the housing is used as a water filling channel. On the one hand, by cleverly setting the water filling structure in the limited space between the housing and the nozzle, the water filling method can be simplified, the user experience can be improved, and the functions of top water filling and nozzle rotation can be taken into account. On the other hand, by cleverly utilizing the connection structure between the nozzle and the housing in the air outlet device, the gap formed is used as a water filling channel, eliminating the need for an additional separate water filling structure, which can effectively reduce structural redundancy, while ensuring the integrity of the appearance and not increasing the overall size of the machine. Furthermore, in the air outlet device structure that includes both the nozzle and the housing, using the gap formed between the nozzle and the upper part of the housing as a water filling channel can provide users with intuitive water filling guidance. Moreover, setting the water filling channel at the top of the housing or the bottom of the nozzle can also prevent the water filling operation from affecting the air outlet of the nozzle.

Detailed Implementation

[0042] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0043] As a specific embodiment of this application, such as Figure 1 , Figure 2 As shown, a first aspect of this application provides a water filling structure for an air outlet device, which may include a housing 100, a nozzle 200, and a water filling channel formed between the housing 100 and the nozzle 200. The housing 100 is used to generate an airflow, and the nozzle is located upstream of the airflow in the housing 100 for emitting the airflow. The nozzle 200 is rotatably disposed on the upper part of the housing 100, and a gap 110 is formed between the nozzle 200 and the upper part of the housing 100, forming a water filling channel. The housing 100 may accommodate an airflow generating device for generating airflow, and the nozzle may include at least one air outlet, through which the airflow generated by the housing 100 can be emitted.

[0044] It is worth noting that the upper part of the housing 100 refers to the area corresponding to the upstream of the airflow. The accompanying drawings of this application embodiment are only for illustration with the nozzle 200 set on the top surface of the housing 100. In actual applications, the nozzle 200 can be set in other upper areas of the housing 100 other than the top surface, as long as the nozzle 200 can emit airflow. This application does not limit the position of the nozzle 200 on the housing 100.

[0045] Specifically, in this embodiment of the air outlet device, a nozzle 200 is rotatably mounted on the upper part of the housing 100, and the gap 110 formed between the nozzle 200 and the upper part of the housing 100 serves as a water filling channel. On the one hand, by cleverly arranging the water filling structure within the limited space between the housing 100 and the nozzle 200, the water filling method can be simplified, the user experience can be improved, and the functions of top water filling and nozzle rotation can be combined. On the other hand, by cleverly utilizing the connection structure between the nozzle 200 and the housing 100 in the air outlet device, the formed gap 110 is used as a water filling channel. 10 serves as a water filling channel, eliminating the need for a separate water filling structure, effectively reducing structural redundancy while maintaining aesthetic integrity and not increasing the overall size of the unit. Furthermore, in the air outlet device structure comprising the nozzle 200 and the housing 100, using the gap 110 formed between the upper part of the nozzle 200 and the housing 100 as a water filling channel provides users with intuitive guidance on water filling. Moreover, setting a water filling channel at the top of the housing 100 or the bottom of the nozzle 200 also prevents the water filling operation from affecting the airflow from the nozzle.

[0046] In one embodiment, the slit 110 may be provided around the outer wall of the bottom of the nozzle 200. The slit 110 may be a shape with a hollow region, such as an annular shape, a hollow rectangle, a hollow triangle, or other hollow polygons. Understandably, the shape of the slit 110 can be selected according to the actual situation. By providing the slit 110 around the outer wall of the bottom of the nozzle 200, a full-angle water filling function can be provided, allowing the user to add water from any position.

[0047] As a specific embodiment of this application, such as Figure 1 , Figure 2 As shown, the gap 110 can be annular.

[0048] In other words, an annular slit 110 is formed between the outer wall of the bottom of the nozzle 200 and the upper part of the housing 100. The slit 110 is arranged around the outer wall of the bottom of the nozzle 200, so that the user can apply water at any angle on the upper part of the housing 100 so that it can flow into the interior of the slit 110.

[0049] In another embodiment, the slit 110 may not necessarily surround the outer wall of the bottom of the nozzle 200; it may simply be formed between the outer wall of the bottom of the nozzle 200 and the upper part of the housing 100. In other words, the slit 110 may not have a hollow region, or the slit 110 may be part of a shape that has a hollow region. In one example, the slit 110 may be arc-shaped, and the arc center angle of the slit 110 may be set to 60°, 90°, 120°, etc., which can be selected according to the actual application. This application does not make specific limitations here. It is understood that, for ease of explanation, the accompanying drawings of this application only illustrate the slit 110 as an annular shape, and this is not a limitation.

[0050] As a specific embodiment of this application, combined with Figure 1 , Figure 2 as well as Figure 3 As shown, the water filling structure of the air outlet device may further include a water filling cover 300. The water filling cover 300 is located on the upper part of the housing 100 and is arranged around the periphery of the nozzle 200. The inner circumferential surface of the water filling cover 300 and the bottom outer wall of the nozzle 200 define a gap 110. By setting the water filling cover 300, it can be used to guide water to flow into the gap 110, improving the user's water filling experience.

[0051] In one example, a water inlet cover 300 is detachably installed on the upper part of the housing 100, and the nozzle 200 is located in the middle empty area of ​​the water inlet cover 300. The inner circumferential surface of the water inlet cover 300 and the bottom outer wall of the nozzle 200 form a gap 110 for adding water. The water inlet cover 300 serves as the water application point to guide water to the gap 110, and its detachability facilitates replacement and maintenance.

[0052] Preferably, combined with Figure 4 , Figure 5 as well as Figure 8 As shown, the height of the upper surface of the water filling cover 300 gradually decreases from the outer periphery to the inner periphery.

[0053] In other words, along the radial direction, from the outer circumferential surface of the water filling cover 300 to the inner circumferential surface, the height of the upper surface of the water filling cover 300 gradually decreases from the outer circumferential surface to the inner circumferential surface. Therefore, when water is applied to any position on the upper surface of the water filling cover 300, it can flow smoothly from the outer periphery to the central gap 110, preventing overflow or accumulation and improving water filling efficiency. As an example, the upper surface of the water filling cover 300 can be a sloping, straight, flat surface; or it can be an arc-shaped surface, the shape of which can be concave downwards or convex upwards relative to the upper part of the shell 100.

[0054] Preferably, combined with Figure 4 , Figure 5 as well as Figure 8 As shown, the upper surface of the water filling cover 300 has a downward concave arc shape in the radial direction.

[0055] In other words, the upper surface of the water filling cover 300 is concave towards the bottom of the shell 100, and the height of the water filling cover 300 gradually decreases from the outer peripheral end to the inner peripheral end. Specifically, according to the principles of fluid mechanics, when water flows through the concave arc surface, due to the shape of the concave arc surface itself, the water will be attracted inward at the edge of the arc surface. More specifically, the curvature of the arc surface causes the flow path of the water to bend at the edge. According to Bernoulli's principle, the pressure is low where the flow velocity is high, while the flow velocity is slower and the pressure is higher at the center of the arc surface compared to the edge. The water is forced towards the center of the arc surface, thus achieving water convergence. That is to say, designing the cross-section of the upper surface of the water filling cover 300 in the radial direction as an arc shape that is concave downward from the outer peripheral side to the inner peripheral side can improve the water collection effect, allowing the water applied to the upper surface of the water filling cover 300 to flow more quickly and effectively to the central gap 110.

[0056] As a specific embodiment of this application, combined with Figure 5 , Figure 9 , Figure 10 as well as Figure 11 As shown, the water filling structure of the air outlet device may also include an inclined guide 400, which is located below the opening of the slit 110 and connected to the bottom outer wall of the nozzle 200. The guide 400 is used to guide the water added through the opening of the slit 110 to the internal water channel.

[0057] It should be noted that the shape of the guide portion 400 is adapted to the opening form of the slit 110, ensuring that the water entering through the slit 110 can reach the guide portion 400. For example, it can be annular or arc-shaped, etc., and this application does not make specific limitations here. The guide portion 400 can be an inclined straight flat surface; or it can be an arc-shaped surface. The shape of the arc-shaped surface can be concave downward or convex upward relative to the upper part of the shell 100, which is not limited here, as long as it can ensure that the guide portion 400 can guide the water entering through the opening of the slit 110 to the internal water channel.

[0058] In one example, the internal water channel refers to a structure that can introduce water into the water tank, such as a water pipe or a water tank, and is not limited thereto. In another example, the internal water channel can also be a water tank. In this example, the outlet of the guide 400 can be set to correspond to the inlet of the water tank, so that the water can be directly guided into the water tank through the guide 400.

[0059] As a specific embodiment of this application, combined with Figure 5 , Figure 10 as well as Figure 11As shown, in this embodiment, the inner end of the guide portion 400 is higher than the outer end of the guide portion 400 in the radial direction, and the outer end of the guide portion 400 is located outside the opening of the slit 110 in the radial direction. Specifically, the guide portion 400 is provided corresponding to the slit opening 111 of the slit 110 (i.e., the cross-section perpendicular to the opening direction of the slit 11), and its inner end is located below the slit opening 111 of the slit 110. The inner end of the guide portion 400 is higher than the outer end of the guide portion 400 in the radial direction, which facilitates the guidance of water falling from the slit opening 111 from the inner end to the internal water channel corresponding to the outer end of the guide portion 400.

[0060] Specifically, an inclined guide portion 400 is provided inside the housing 100. For example, the guide portion 400 can be annular. The inner circumferential surface of the annular guide portion 400 is connected to the bottom outer wall of the nozzle 200, and the outer circumferential surface of the guide portion 400 is located at the end away from the bottom of the nozzle 200. Along the radial direction from the inner circumferential surface to the outer circumferential surface of the guide portion 400, the height of the upper surface of the guide portion 400 gradually decreases. Thus, the guide portion 400 is located below the slit opening 111 of the slit 110, and the water falling into the slit opening 111 is guided from top to bottom to a predetermined position, which is the aforementioned internal water channel.

[0061] As a specific embodiment of this application, the outer end of the guide portion 400 is located outside the slit opening 111 in the radial direction. That is, the outer end (i.e., the outer peripheral end) of the guide portion 400 is located on the side away from the slit opening 111 in the radial direction of the guide portion 400, so that the projected width of the radius length of the upper surface of the guide portion 400 relative to the reference plane where the slit opening 111 is located is greater than the width of the slit opening 111. As a result, when water falling into the slit opening 111 falls onto the guide portion 400, it is buffered by the distance between the inner end and the outer end of the guide portion 400 until it flows to the far end that is offset from the slit opening 111, which can effectively prevent the water falling into the slit opening 111 from directly impacting the inner end of the guide portion 400 and overflowing.

[0062] In one example, the guide 400 may be made of a light-transmitting material, and a light strip may be provided on the upper side of the guide 400 away from the housing 100. The light strip can illuminate the gap opening 111 through the guide 400, which can serve as an ambient light and also as a water-adding prompt to guide the user to add water.

[0063] As a specific embodiment of this application, such as Figure 5 As shown, the water filling structure of the air outlet device may also include a water tank 500, which is located below the outer end of the guide portion 400 inside the housing 100.

[0064] Specifically, in this embodiment, the water filling structure of the air outlet device also includes a water tank 500 inside the housing 100. The water tank 500 is located below the outer end of the guide section 400 to receive water discharged from the guide section 400. For example, the inner wall of the water tank 500 in the radial direction is connected to the outer end of the guide section 400. Water falling on the guide section 400 falls from its outer end into the inner wall of the water tank 500, thereby achieving water collection by the water tank 500. It should be noted that the arrangement of the water tank 500 is also adapted to the arrangement of the guide section 400, as long as the water on the guide section 400 can flow into the water tank 500. For example, it can be annular or arc-shaped, etc., and this application does not make specific limitations here. It is understood that the height or depth of the water tank 500 can be set according to the water filling requirements and the actual internal space of the housing 100. Generally speaking, when a higher water filling volume and a faster water filling speed are required, a deeper water tank 500 can be set.

[0065] As a specific embodiment of this application, such as Figure 6 and Figure 7 As shown, a low point area 520 is formed on the inner bottom surface of the water tank 500, and the height of the low point area 520 is lower than the height of any other inner bottom surface area of ​​the water tank 500.

[0066] Specifically, the bottom surface of the water tank 500 has a slope, with one side of the bottom surface being lower than the other, forming a low point area 520. The height of the low point area 520 is lower than the height of any other bottom surface area of ​​the water tank 500, so that the water collected by the water tank 500 is gathered in the low point area 520, making it easier to concentrate the water collected in the low point area 520 into the internal water channel, such as a water pipe or water tank.

[0067] Understandably, in practical applications, one or more low-point areas 520 can be set according to the shape of the water tank 500 and actual needs; this application does not impose any limitations. In one example, the water tank 500 is a closed ring, in which case one low-point area 520 can be set, the height of which is lower than the height of the inner bottom area of ​​any other water tank 500, thereby facilitating water drainage. In another example, the water tank 500 may be an open arc segment, in which case two low-point areas 520 can be set at the two ends of the water tank 500 to further increase the drainage speed. The height of each low-point area 520 is lower than the height of the other bottom areas of the water tank segment it is located in, and the heights of the various low-point areas 520 may or may not be the same.

[0068] In one embodiment, combined with Figure 6 and Figure 7As shown, the water filling structure of the air outlet device may also include a drain pipe 700, which is used to connect the low point area 520 of the water tank 500 and the water tank. That is, the water collected in the low point area 520 of the water tank 500 is transported to the water tank in the housing 100 through the drain pipe 700.

[0069] As a specific embodiment of this application, such as Figure 5 As shown, a bottom plate 310 is also formed on the inner bottom surface of the water filling cover 300, and the bottom surface of the bottom plate 310 is sealed to the outer side wall of the water tank 500 in the radial direction.

[0070] Specifically, such as Figure 5 As shown, a base plate 310 is provided on the inner bottom surface of the water filling cover 300. One end of the base plate 310 is connected to the inner circumferential surface of the water filling cover 300, and the other end is connected to the outer circumferential surface of the water filling cover 300. The bottom surface of the base plate 310 near the outer circumferential surface of the water filling cover 300 is sealed to the outer side wall of the water tank 500 in the radial direction, so that the water filling passage of the gap opening 111, the guide part 400 and the water tank 500 part forms a sealed channel, preventing water from leaking into the outer shell 100 of the guide part 400 and the water tank 500, thereby effectively protecting other components inside the shell 100 from damage.

[0071] In one instance, such as Figure 5 As shown, a sealing ring 311 can be provided on the upper part of the outer side wall of the water tank 500 in the radial direction. The bottom of the base plate 310 is sealed to the outer side wall of the water tank 500 by the sealing ring 311, thereby further improving the sealing performance of the water filling passage.

[0072] As a specific embodiment of this application, such as Figure 5 As shown, the water tank 500 has an opening at the top. The water filling structure of the air outlet device may also include a filter structure 600, which is disposed inside the housing 100 and located between the opening of the water tank 500 and the outer end of the guide portion 400.

[0073] Specifically, the top of the water tank 500 has an upward-facing opening 510. The water supply structure of the air outlet device includes a filter structure 600 inside the housing 100. This filter structure 600 is positioned above the water tank opening 510 and connects to the outer end of the guide portion 400. The filter structure 600 filters the water guided by the guide portion 400 before it enters the water tank 500, reducing the impurity content in the water and ensuring the air outlet device's performance. This also reduces damage to internal components of the air outlet device and extends its service life.

[0074] As a specific embodiment of this application, combined with Figure 5 , Figure 10 and Figure 11As shown, the filter structure 600 may include a filter support 610 and a filter body 620 connected to the filter support 610. The filter support 610 is connected to the outer end of the guide portion 400, and the filter body 620 is disposed on the outer end of the filter support 610.

[0075] As a specific embodiment of this application, such as Figure 5 As shown, the opening of the water tank 500 is located below the filter screen body 620.

[0076] In other words, the water tank opening 510 of the water tank 500 is located below the filter screen body 620 to ensure that the water filtered by the filter screen body 620 flows into the water tank 500. Preferably, the width of the opening of the water tank 500 in the radial direction is greater than or equal to the width of the filter screen body 620, so as to accommodate the portion of the filter screen support 610 corresponding to the filter screen body 620.

[0077] Specifically, the filter structure 600 may include a filter screen support 610 and a filter screen body 620. The filter screen support 610 is connected to the outer end of the guide portion 400 and is located above the water tank opening 510. The filter screen body 620 is detachably mounted on the filter screen support 610, so that the outer end of the guide portion 400 guides water to the filter screen body 620 on the filter screen support 610 for filtration. The filtered water enters the water tank 500 through the water tank opening 510. By designing the filter screen body 620 to be detachable, it is easy to remove and clean the filter screen body 620.

[0078] In one example, in conjunction with the design of the removable filter body 620, the water filling cover 300 can also be made removable to facilitate the removal of the filter body 620.

[0079] As a specific embodiment of this application, such as Figure 11 As shown, a hollow mounting area 611 is formed on the upper and lower surfaces of the outer periphery of the filter support 610 along the thickness direction, and the filter body 620 is disposed on the mounting area 611.

[0080] Specifically, the filter support 610 can be arc-shaped or annular. Hollow mounting areas 611 are formed on the upper and lower surfaces of the arc-shaped or annular filter support 610 along its thickness direction. There can be one or more mounting areas 611 circumferentially disposed on the filter support 610. The filter body 620 can also be one or more correspondingly detachably disposed on the mounting area 611. The structure is simple, reliable, and easy to replace and maintain. In one example, the filter body 620 can be magnetically connected to the mounting area 611.

[0081] As a specific embodiment of this application, such as Figure 7 and Figure 11As shown, a first baffle plate 612 is formed on the outer end of the filter support 610.

[0082] Specifically, a first baffle plate 612 extending along its thickness direction is formed on the upper surface of the outer end of the filter screen support 610. The first baffle plate 612 is located on the outer periphery of the filter screen body 620 and is used to block the water guided by the guide part 400 onto the filter screen body 620, preventing it from falling directly into the water tank 500 without being filtered by the filter screen body 620. Preferably, the first baffle plate 612 extends higher than the upper surface of the filter screen body 620 along the thickness direction of the filter screen support 610, thereby ensuring a blocking effect on the outer side of the filter screen body 620.

[0083] As a specific embodiment of this application, combined with Figure 5 , Figure 10 and Figure 11 As shown, a second baffle plate 420 extends upward along the thickness direction from the inner end of the guide portion 400 in the radial direction, and the bottom of the nozzle 200 is fitted onto the second baffle plate 420.

[0084] Specifically, a connecting bracket 410 is formed on the inner end of the guide portion 400. A second baffle plate 420 extends circumferentially upward from the connecting bracket 410. A recessed annular groove 210 is formed at the bottom of the nozzle 200. The bottom of the nozzle 200 is rotatably fitted onto the second baffle plate 420 through the annular groove 210, for example, with a clearance fit. The second baffle plate 420 is used to block water added at the slit opening 111 to prevent it from seeping into the nozzle 200. The second baffle plate 420 is configured to correspond to the arrangement shape of the slit 110, and can be arc-shaped or annular. Preferably, the height of the second baffle plate 420 is greater than the height of the outer peripheral end of the water filling cover 300, thereby further preventing water applied at the water filling cover 300 from overflowing the second baffle plate 420.

[0085] A second aspect of this application provides a water filling structure for an air outlet device, including a housing 100, a nozzle 200, and a water filling channel formed between the housing 100 and the nozzle 200.

A gap 110 is formed between the nozzle 200 and the upper part of the housing 100, and the gap 110 forms a water filling channel.

[0086] In one example, the bottom of the nozzle 200 can be fixedly disposed on the upper part of the housing, and the nozzle 200 can be an elliptical annular nozzle extending away from the upper part of the housing 100. It is understood that the water filling structure of this embodiment further defines the arrangement and structure of the nozzle compared with the water filling structure of the above embodiment, while other parts are the same and will not be described in detail here.

It is understood that this application does not limit the location of the water tank; it may be located at the bottom, middle, or other suitable position of the housing 100.

[0088] Since the air outlet device in this embodiment includes the water filling structure of the above embodiment, its features and corresponding beneficial effects are the same as those described above, and will not be repeated here.

[0089] A third aspect of this application provides a humidification device, including a water filling structure and a water tank. The water filling structure includes a housing 100, a nozzle 200, and a water filling channel formed between the housing 100 and the nozzle 200.
