[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] The air handling components and child vehicles of this application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0041] In existing technologies, air is treated using air handling components such as humidifiers. However, the air treatment effect is limited and the treatment range is small, which cannot meet the needs of users.

[0042] To address the aforementioned technical problems, this application provides an air handling assembly, including a mounting housing, an air purification structure, and an air humidification structure. The air purification structure and the air humidification structure are jointly disposed within the mounting housing, and the air outlet of the air purification structure is located at the top of the spray nozzle of the air humidification structure. This will be described in detail below.

[0043] See Figure 1 , Figure 3 as well as Figure 8 The air handling unit 20 includes a mounting housing 21, an air purification structure 23, and an air humidification structure 22. The air purification structure 23 and the air humidification structure 22 are both disposed in the mounting housing 21, and the air outlet 2311 of the air purification structure 23 is disposed on top of the spray nozzle 2211 of the air humidification structure 22.

[0044] The air humidification structure 22 is used to provide water mist to the air, humidify the air, and provide a comfortable environment; the air purification structure 23 is used to purify the air, ensure the air is fresh, and also provide a comfortable environment; in this application, the air humidification structure 22 and the air purification structure 23 are combined to provide both fresh air and ensure the air humidity, thus providing a comfortable environment and avoiding overly simplistic air treatment.

[0045] The air outlet 2311 of the air purification structure 23 is located on top of the spray nozzle 2211 of the air humidification structure 22. While the spray nozzle 2211 sprays water mist, the purified air can blow the water mist further (the air blown out of the air outlet 2311 can increase the flow rate of the water mist sprayed out of the spray nozzle 2211, so that the water mist can spread further), thereby increasing the coverage of water mist and purified air and expanding the range of air treatment.

[0046] It is worth mentioning that the air humidification structure 22 and the air purification structure 23 are both mounted on the mounting housing 21. Since they are mounted on the same component, during actual assembly, only the mounting housing 21 needs to be installed to assemble the air handling component 20, which helps to improve assembly efficiency. At the same time, it can ensure the accuracy of the relative position between the air outlet 2311 and the spray nozzle 2211, enhance the strengthening effect of fresh air on water mist (making the water mist travel further), and improve the air handling quality.

[0047] It should be noted that in actual use, the air purification structure 23 and the air humidification structure 22 can be installed in the required places by installing the housing 21, such as the support leg 10 of the child vehicle in some embodiments, and not limited to this.

[0048] See Figure 1 , Figure 3 , Figure 6 , Figure 8 as well as Figure 11 The mounting housing 21 has a accommodating groove 60 on its peripheral wall; the air purification structure 23 includes a fan 231 and a filter element 232. The fan 231 is connected to the top of the mounting housing 21, and the filter element 232 is accommodated in the accommodating groove 60. The filter element 232 has an air inlet 2321 and an air outlet 2322, and the fan 231 has an air inlet 2312 and an air outlet 2311. The air outlet 2322 of the filter element 232 is arranged opposite to the air inlet 2312 of the fan 231, and the air inlet 2321 of the filter element 232 and the air outlet 2311 of the fan 231 face the same direction.

[0049] The air inlet 2321 of the filter element 232 and the air outlet 2311 of the fan 231 face the same direction, meaning they both act on the air in the same area, which is referred to as the target area for ease of explanation. The air inlet 2321 faces the target area, meaning it is connected to the target area, and the air outlet 2322 is positioned opposite to the air inlet 2312. When the fan 231 is started, a negative pressure is formed near the air inlet 2312 of the fan 231. The air in the target area enters the air inlet 2321 of the filter element 232 under the action of air pressure, and after being filtered by the filter element 232, it is discharged from the air outlet 2322 of the filter element 232, forming fresh air. This fresh air is then re-entered into the target area from the air outlet 2311 of the fan 231 under the action of the fan 231, providing fresh air to the target area. The structure is simple and easy to use.

[0050] In this embodiment, the air purification structure 23 can circulate the air inside the target area, replacing the originally polluted air in the target area with treated fresh air. This cycle is repeated to ensure that the air inside the target area remains fresh. In the prior art, fresh air is often directly supplied to the target area, while the originally polluted air inside the target area still exists. Compared with the exhaust of polluted air in this application, the air treatment effect is poor, and the comfort level in the target area is generally low.

[0051] It is worth mentioning that the inclusion groove 60 enables quick assembly and disassembly of the filter element 232 and prevents leakage of the filter element 232, which is beneficial to the cleanliness of the filter material inside the filter element 232 and improves its service life. In addition, the top of the inclusion groove 60 is provided with an opening (as long as it does not obstruct the passage of gas, and in some embodiments it can be arranged in other forms), so that the fresh air discharged from the air outlet 2322 of the filter element 232 can enter the internal cavity of the mounting housing 21 and be discharged by the top fan 231 under the guidance of the internal cavity of the mounting housing 21 (entering the target area).

[0052] It should be noted that the peripheral wall of the mounting housing 21 is the side wall of the mounting housing 21 around the vertical direction (i.e., the direction of gravity).

[0053] Referring to 6-8, the receiving groove 60 has a first groove segment 61 and a second groove segment 62 in a first direction. The first groove segment 61 is disposed between the second groove segment 62 and the fan 231, and the filter element 232 is snapped into the first groove segment 61. The air inlet 2321 and the air outlet 2322 of the filter element 232 are disposed opposite to each other in a first direction, which is parallel to the direction of gravity.

[0054] In the first direction, the air inlet 2321 and the air outlet 2322 are arranged opposite to each other, that is, the air inlet 2321 and the air outlet 2322 are located inside the receiving groove 60, which is not easily affected by the outside (the outside is not easily contaminated by the filter material inside the filter element 232). The second groove section 62 provides air intake space for the air inlet 2321. The air inlet 2321 does not face the target area directly, which can also avoid the air inlet 2321 from being blocked and improve its service life.

[0055] In this embodiment, the filter element 232 is snapped into the first groove segment 61. The filter element 232 can be inserted into the first groove segment 61 in a manner similar to a drawer, but is not limited to this.

[0056] In some embodiments, the air inlet 2321 and the air outlet 2322 may not be arranged opposite each other. For example, the air inlet 2321 may be located on the surface of the filter element 232 facing the target area, and the air outlet 2322 may be located on the top of the filter element 232. This is not limited to the above and may be designed according to the specific use.

[0057] It should be noted that the filter material inside filter element 232 can be activated carbon, etc., and no specific limitation is made here.

[0058] In some embodiments, the surface of the filter element 232 away from the bottom of the receiving groove 60 is provided with a disassembly block 2323.

[0059] The disassembly block 2323 facilitates the gripping of the filter element 232 during disassembly and assembly, thus improving the ease of disassembly and assembly of the filter element 232.

[0060] It should be noted that the surface of the filter element 232 that is away from the bottom of the receiving groove 60 is the surface of the filter element 232 facing the target area. With this setting, the disassembly block 2323 will not affect the arrangement of other components, and the structural arrangement is reasonable.

[0061] In some embodiments, the air purification structure 23 further includes a negative ion generator 233, which is adapted to the fan 231.

[0062] Before being exhausted by the fan 231, the purified air passes through the negative ion generator 233 to ensure the freshness of the air entering the target area and improve the comfort level inside the target area.

[0063] In some embodiments, the negative ion generator 233 is disposed on the side of the fan 231, which has a compact structure and reasonable layout, reducing the space occupied by the negative ion generator 233.

[0064] In some embodiments, the air humidification structure 22 includes a humidifier 221, a water inlet 222, and a water tank 223. The water tank 223 is connected to the bottom of the mounting housing 21, the humidifier 221 is disposed on the top of the mounting housing 21, one end of the water inlet 222 is inserted into the inside of the water tank 223, and the other end of the water inlet 222 is housed inside the mounting housing 21 and connected to the humidifier 221.

[0065] The humidifier 221 and the water tank 223 are respectively located at the top and bottom of the mounting housing 21. That is, the air humidification structure 22 extends along the first direction (i.e., the vertical direction) and is installed using the longitudinal space. The longitudinal space is rationally utilized. The air handling component 20 has a compact overall structure and can be installed in a narrow space, which enhances the diversity of usage scenarios and has a reasonable structural layout.

[0066] Water in the top water tank 223 is guided to the top humidifier 221 by the water guide 222, and after being processed by the humidifier 221, it is sprayed out from the spray nozzle 2211. The water guide 222 can be a sponge column or the like, but is not limited to this.

[0067] In some embodiments, to prevent moisture from evaporating and being lost when passing through the interior of the mounting housing 21, a protective sleeve 2111 is provided inside the mounting housing 21, and a water guide 222 is inserted into the protective sleeve 2111. One end of the protective sleeve 2111 is connected to the water tank 223, and the other end is connected to the humidifier 221.

[0068] See Figure 9 The water tank 223 is snapped onto the bottom of the mounting housing 21, and the peripheral wall of the water tank 223 is provided with a gripping part 2231; a cross section λ is set perpendicular to the first direction, and the cross section obtained by the cross section crossing the gripping part 2231 is T-shaped, and the first direction is parallel to the direction of gravity.

[0069] By setting the gripping part 2231, it is convenient for operators to disassemble the water tank 223, reducing the difficulty of disassembling and assembling the water tank 223; and in this embodiment, the gripping part 2231 has a T-shaped cross section, which conforms to ergonomics and facilitates gripping force.

[0070] The water tank 223 is snapped onto the bottom of the mounting housing 21. The snap-fit ​​structure 50 between the water tank 223 and the mounting housing 21 can be a snap-fit ​​block 51 and a snap-fit ​​groove 52 (e.g., Figure 2 The specific settings, such as those shown, will not be explained here.

[0071] In some embodiments, the water tank 223 may also be integrally set with the mounting housing 21, and water replenishment can be performed through a reserved water inlet, but it is not limited to this.

[0072] It is worth mentioning that in some embodiments, the gripping part 2231 can be hollow and communicate with the inside of the water tank 223. The hollow part of the gripping part 2231 can hold water, which increases the capacity of the water tank 223 and helps to extend the service life of the air humidification structure 22 without the need for frequent water filling.

[0073] On the other hand, this application also relates to a child vehicle including any of the aforementioned air handling components 20.

[0074] Children's vehicles typically include playpens, strollers, and cribs. The following description uses a crib as an example: A crib typically includes support legs 10. The surface of the support legs 10 facing the inside of the crib has mounting grooves 11. The mounting grooves 11 extend along the length of the support legs 10, and the opening of the mounting grooves 11 faces the inside of the crib. A mounting housing 21 is embedded in the mounting grooves 11 (in some embodiments, the mounting housing 21 may also be located at other positions on the support legs 10, depending on the actual shape of the crib, and is not limited to this).

[0075] An installation groove 11 is provided on the support leg 10. The assembly difficulty is reduced by the mutual cooperation between the installation housing 21 and the installation groove 11. The installation housing 21 (air purification structure 23 and air humidification structure 22) is installed in the space of the support leg 10, which avoids encroaching on the internal space of the children's bed and improves the space utilization rate. In addition, children are less likely to touch it during use, avoiding collisions, scratches and other injuries to children, thus improving the safety of the children's bed.

[0076] It is worth mentioning that the mounting groove 11 is located on the surface of the support leg 10 facing the inside of the children's bed. That is, after the air handling unit 20 is installed, the air humidification structure 22 and the air purification structure 23 face the inside of the children's bed, which can better improve the humidity and freshness of the air inside the children's bed. The arrangement is reasonable. The mounting groove 11 is located inside the support leg 10, which can also effectively avoid external interference. The air handling unit 20 is not easily damaged by external forces. The support leg 10 can protect the air handling unit 20 well, which can effectively improve the service life of the air handling unit 20.

[0077] It should be noted that the interior of the children's bed refers to the internal space of the children's bed used by children, which is also the target area in the aforementioned embodiments.

[0078] See Figure 4 as well as Figure 5The support leg 10 is provided with a bearing portion 12, which is disposed on the top of the mounting groove 11; the mounting housing 21 includes a main body portion 211 and a fixing portion 212, which is disposed on the periphery of the main body portion 211 around a first direction, the first direction being parallel to the length direction of the support leg 10; the top of the mounting groove 11 is provided with an insertion opening 111, through which the main body portion 211 is inserted into the mounting groove 11, and the fixing portion 212 is fixedly connected to the top of the bearing portion 12.

[0079] The top of the mounting slot 11 is provided with an insertion opening 111, which means that the mounting housing 21 can be assembled from top to bottom. When the main body 211 is inserted into the mounting slot 11, the fixing part 212 is supported by the bearing part 12, which helps to improve the stability of the mounting housing 21 during the assembly process and facilitates the subsequent connection operation between the fixing part 212 and the bearing part 12. The mounting housing 21 is fixed through the fixed connection between the fixing part 212 and the bearing part 12. The structure is simple and easy to use.

[0080] In this embodiment, there are two fixing parts 212, which are symmetrically arranged on both sides of the main body 211. Correspondingly, there are also two supporting parts 12, which helps to improve the stability of the installation of the housing 21. In this embodiment, the fixing parts 212 and the supporting parts 12 can be fixedly connected together by screws. In some embodiments, they can also be connected by riveting or by adhesive, etc., and are not limited to these.

[0081] In some embodiments, the height of the support 12 on the support leg 10 can be changed to achieve different installation heights of the mounting housing 21 (i.e., air handling assembly 20). By changing the installation height, the positions of the spray nozzle 2211 and the air outlet 2311 can be adjusted. The height of the spray nozzle 2211 and the air outlet 2311 can be adjusted according to factors such as temperature and humidity in the actual use environment, so that the child in the crib is in a comfortable environment and the comfort of use is improved.

[0082] It should be noted that the mounting groove 11 also has a slot opposite to the bottom of the mounting groove 11. When installing the mounting housing 21, the mounting housing 21 can also be installed through this slot. Specifically, the mounting housing 21 is moved horizontally (perpendicular to the first direction, which is the vertical direction) toward the slot. The mounting housing 21 enters through the slot and is embedded in the mounting groove 11. At this time, the fixing part 212 is located above the supporting part 12. The mounting housing 21 can be moved downward until the fixing part 212 is placed on the supporting part 12. Finally, the fixing part 212 and the supporting part 12 are connected and installed.

[0083] In some embodiments, the surface of the support leg 10 facing the inside of the children's bed may also be provided with two protruding ridges, which are parallel to each other and define the mounting groove 11, and the bearing portion 12 is the top of the protruding ridges, but not limited thereto.

[0084] See Figure 10 The mounting groove 11 has a limiting wall 112 that is relatively arranged in the width direction, and the mounting housing 21 is sandwiched between the limiting wall 112. The children's bed also includes a railing mounting seat 30, which is connected to the support leg 10, and the fixing part 212 abuts against the side wall of the railing mounting seat 30 around the first direction. The side wall of the railing mounting seat 30 that abuts against the fixing part 212 is called the first surface 321. The first surface 321 intersects with the limiting wall 112 to form a limiting angle β, and the open end of the limiting angle β faces the outside of the children's bed.

[0085] The railing mounting base 30 is used to install the railings required for the children's bed. The railing mounting base 30 is set on the support leg 10, and the side wall of the railing mounting base 30 (i.e., the side wall around the first direction, i.e., the first surface 321; in this embodiment, there are two railing mounting bases 30, and the two railing mounting bases 30 are respectively set on opposite sides of the mounting groove 11, i.e., the side wall of the railing mounting base 30 facing the mounting groove 11 abuts against the fixing part 212) abuts against the fixing part 212. By setting the limiting wall surface 112 and the first surface 321, the relative position of the mounting housing 21 and the support leg 10 in a preset direction (any direction perpendicular to the first direction) can be limited, thereby improving the stability of the mounting housing 21 assembly and also improving the assembly efficiency of the mounting housing 21.

[0086] Specifically, the main body 211 is inserted between the limiting walls 112. The limiting walls 112 restrict the main body 211 (i.e., the fixing part 212). At this time, the main body 211 only tends to move towards the inside of the children's bed (movement in the first direction is not discussed here). At the same time, the fixing part 212 abuts against the first surface 321, and the first surface 321 and the limiting walls 112 are set at a limiting angle β. Since the open end of the limiting angle β faces the outside of the children's bed, the first surface 321 can block the fixing part 212 and prevent the fixing part 212 from moving towards the inside of the children's bed. That is, the setting of the limiting walls 112 and the first surface 321 restricts the relative position of the mounting housing 21 and the support leg 10 in the preset direction.

[0087] In actual installation, the mounting housing 21 can only be installed from top to bottom. It is embedded in the mounting groove 11 through the insertion opening 111, which simplifies the assembly steps. The installation can be completed simply by inserting the mounting housing 21 from top to bottom, thus improving the assembly efficiency of the mounting housing 21.

[0088] It should be noted that the width direction of the mounting groove 11 is the direction perpendicular to the limiting wall surface 112 (e.g., Figure 6 (middle horizontal); the open end of the limiting angle β corresponds to the closed end, and the closed end of the angle is the vertex end of the angle; the contact part between the fixing part 212 and the first surface 321 can be a surface, a line, etc., and is limited according to the specific shape required by the fixing part 212.

[0089] It is worth mentioning that the railing is generally set at the top of the children's bed, that is, the railing mounting base 30 is set at the top of the children's bed, which also means that the air handling unit 20 is set at the top of the children's bed. In actual use, the sprayed water mist and fresh air can gradually fall from above the children's bed and fill the entire interior of the children's bed, improving the comfort of using the children's bed.

[0090] In some embodiments, the water tank 223 is housed in the mounting groove 11, and in a first direction, the water tank 223 is detachably snapped onto the bottom of the mounting housing 21, the first direction being parallel to the length direction of the support leg 10; the bottom of the water tank 223 is spaced apart from the bottom of the mounting groove 11.

[0091] In the first direction, the water tank 223 is detachably snapped onto the bottom of the mounting housing 21, that is, the water tank 223 can be disassembled and assembled along the first direction. When there is no water in the water tank 223, the water tank 223 is disassembled for water replenishment. After water replenishment, the water tank 223 is then inserted back into the bottom of the mounting housing 21 along the first direction.

[0092] The bottom of the water tank 223 is spaced apart from the bottom of the mounting groove 11, providing space for the water tank 223 to move and facilitating its disassembly and assembly. Simultaneously, the water tank 223 is housed within the mounting groove 11, meaning that during disassembly and assembly, the water tank 223 moves vertically within the mounting groove 11. The mounting groove 11 provides lateral restraint for the water tank 223. During disassembly and assembly, the force direction of the water tank 223 is approximately along the first direction (i.e., the vertical direction), preventing excessive force deviation (an excessively large angle between the force direction and the first direction) from affecting the stability of the mounting housing 21 (i.e., the humidifier 221) during disassembly and assembly.

[0093] In some embodiments, the support leg 10 is further provided with a plug hole 13 facing the inside of the child bed, and the plug hole 13 extends along a first direction; the railing mounting base 30 includes a plug part 31 and a mounting part 32, the mounting part 32 is disposed on the top of the plug part 31, and a first surface 321 is disposed on the mounting part 32; the plug part 31 is plugged into the plug hole 13, and the end face of the mounting part 32 facing the plug part 31 abuts against the top of the bearing part 12.

[0094] The insertion hole 13 extends along the first direction, that is, the installation direction of the fence mounting block is also from top to bottom, which is consistent with the installation direction of the mounting housing 21. There will be no interference between the installation of the mounting housing 21 and the installation of the fence mounting seat 30, and the consistent installation direction simplifies the installation and helps to improve the overall installation efficiency.

[0095] It is worth mentioning that the installation direction of the housing 21 and the rod mounting base 30 is from top to bottom. They can be installed by simply moving them downwards from the top of the support leg 10, which will not damage the integrity of the support leg 10 and will help improve the overall aesthetics of the children's bed.

[0096] When the insertion part 31 is inserted into the insertion hole 13 and is in place, the mounting part 32 presses against the bearing part 12, allowing a direct view of whether the retaining rod mounting seat 30 is installed in place. As can be seen from the previous embodiment, the fixing part 212 also abuts against the top of the bearing part 12. That is, the mounting part 32 and the fixing part 212 abut against the top of the bearing part 12 at the same time. The two (the mounting part 32 and the fixing part 212, i.e., the mounting housing 21 and the retaining rod mounting seat 30) share a common reference (the bearing part 12), which helps to improve the installation accuracy between the two and ensures the limiting effect of the first surface 321 on the fixing part 212. For details, please refer to the previous embodiment, which will not be repeated here.

[0097] In the actual assembly process, the retaining rod fixing seat is first inserted into the insertion hole 13. The retaining rod fixing seat can be fixedly connected to the support leg 10 by screws or other fasteners to complete the installation of the retaining rod mounting seat 30. At this time, the first surface 321 and the limiting wall surface 112 together define the installation range of the mounting housing 21. The mounting housing 21 moves from top to bottom toward the mounting groove 11 until the fixing part 212 is pressed against the top of the bearing part 12, thus completing the installation of the mounting housing 21 (i.e., the air treatment assembly 20). The structure is simple and the installation is convenient.

[0098] In some embodiments, to facilitate the insertion of the plug-in part 31 into the plug-in hole 13, a guide structure 40 may be provided. For example, the guide structure 40 includes a guide groove 41 and a guide protrusion 42. Both the guide groove 41 and the guide protrusion 42 extend along a first direction. The guide groove 41 is disposed on one of the hole wall of the plug-in hole 13 and the plug-in part 31, and the guide protrusion 42 is disposed on the other. When the plug-in part 31 is inserted, the plug-in part 31 is guided into the plug-in hole 13 by the cooperation of the guide groove 41 and the guide protrusion 42, which improves the convenience of assembly, and is not limited to this.

[0099] In some embodiments, the support leg 10 is hollow, and the wire 80 of the air handling assembly 20 is housed inside the support leg 10, with the wire 80 extending from the top of the support leg 10 to the bottom of the support leg 10.

[0100] The support leg 10 is hollow, providing space for the wire 80 to run. The wire 80 is housed inside the support leg 10, preventing it from being exposed and messy, and extending its service life. In addition, the wire 80 provides power and signals to the air humidification structure 22 and the air purification structure 23. When connected to external cables, the connection point of the external cable (connection point with the wire 80) is low because the wire 80 is guided to the bottom of the support leg 10, making it less likely to be kicked by people outside the crib (parents). (If the position is higher, parents are more likely to bump into the external cable, causing the external cable to disconnect from the wire 80.) This ensures the smooth operation of the air humidification structure 22 and the air purification structure 23.

[0101] It should be noted that the conductor 80 extends to the bottom of the support leg 10 and has an interface 81, through which external cables are connected to the conductor 80.

[0102] In some embodiments, the top of the support leg 10 is provided with a cover plate 70, which can protect components such as the negative ion generator 233 and the fan 231, and can also limit the position of each component, which is beneficial to improving the stability of the installation.

[0103] In some embodiments, the air handling assembly 20 further includes a shield 24, which has an air outlet 241 and a spray hole 242. The air outlet 241 is arranged around the spray hole 242. The air outlet 241 is arranged in the air outlet direction of the air purifying structure 23's air outlet 2311, and the spray hole 242 is arranged in the spray direction of the air humidifying structure 22's spray outlet 2211.

[0104] The shield 24 provides protection for the air outlet 2311 and the spray nozzle 2211, preventing external collisions and pollution. In addition, the air outlet 241 and the spray nozzle 242 (smaller aperture, increased flow rate) help to increase the flow rate of the fluid (fresh air and mist required for humidification), ensuring that the fluid travels further and improving the coverage of the fluid inside the children's bed.

[0105] The technical solution provided in this application aims to combine the air humidification structure 22 and the air purification structure 23 to provide both fresh air and maintain air humidity, thus creating a comfortable environment and avoiding overly simplistic air treatment. The air outlet 2311 of the air purification structure 23 is located at the top of the spray nozzle 2211 of the air humidification structure 22. While the spray nozzle 2211 sprays water mist, the purified air can blow the water mist further, increasing the coverage of the water mist and the purified air, and expanding the range of air treatment.
