[0013] In one embodiment, the first reinforcing rib is connected to the end of the insertion rib away from the functional module and forms a first limiting step with the insertion rib, and the insertion port of the insertion groove abuts against the first limiting step.

[0014] In one embodiment, a second limiting step is formed at the lower edge of the first panel, the first reinforcing rib abuts against the second limiting step, and the outer side of the second panel is flush with the outer side of the first panel.

[0015] In one embodiment, the second panel is detachably disposed over the mounting port.

[0036] This utility model proposes an air supply device.

[0037] Please refer to Figures 1 to 3 In one embodiment of this utility model, the air supply device includes:

[0038] The housing 100 includes a first panel 110 and a second panel 120 distributed vertically. The housing 100 has a mounting opening 130. The second panel 120 is closable and covers the mounting opening 130, and its upper end is hooked to the first panel 110.

[0039] Functional module 200 is disposed on housing 100 and is disposed opposite to second panel 120.

[0040] The technical solution of this utility model connects the second panel 120 located below the first panel 110 to the first panel 110. When the second panel 120 repeatedly opens and closes the mounting port 130 to meet the needs of the functional module 200, the upper end of the second panel 120 is hung on the first panel 110. This reduces the gap between the upper edge of the second panel 120 and the first panel 110 caused by gravity pulling, thereby ensuring the stability of the gap between the second panel 120 and the first panel 110 when the mounting port 130 is closed. Furthermore, by connecting the second panel 120 to the first panel 110, the overall integrity of the first panel 110 and the second panel 120 in terms of stress or deformation is ensured, reducing the probability of deformation of the second panel 120 relative to the first panel 110, thereby improving the overall integrity and aesthetics of the air supply equipment.

[0041] It should be noted that the second panel 120 is closable and covers the mounting opening 130. The periphery of the second panel 120 can maintain a fixed connection with one of the periphery points of the mounting opening 130, while the other edges are detachably connected. This allows the second panel 120 to open and close the mounting opening 130 with its fixedly connected edge as the center. For example, the second panel 120 can be fixedly hooked to the first panel 110 with only its upper edge, while the other edges are detachably connected to the periphery of the mounting opening 130. This allows the second panel 120 to open and close the mounting opening 130 with its upper edge fixedly hooked to the first panel 110. Alternatively, the second panel 120 can be fixedly connected to the housing 100 with its horizontal side edge, while the other edges are detachably connected to the periphery of the mounting opening 130. This allows the second panel 120 to open and close the mounting opening 130 with its horizontal side edge fixedly connected to the housing 100. The single-sided fixed connection can be a hinged rotation connection or a snap-fit ​​movable connection. Alternatively, the periphery of the second panel 120 may be detachably connected to the mounting opening 130, ensuring the stability of the connection between the second panel 120 and the first panel 110. The edges of the second panel 120, excluding the upper edge, may be directly connected to the housing 100 or connected to the functional module 200, which then fixes it to the housing 100 to achieve a stable opening and closing mechanism covering the mounting opening 130.

[0042] In one embodiment, please refer to Figure 1 and Figure 3The functional module 200 is configured as at least one of the following: a fresh air module, a humidification module, a sterilization module, and a purification module. The fresh air module provides fresh air drawn in from outdoors; the humidification module adjusts the humidity of the air before blowing it into the room; the purification module purifies the air by removing odors or impurities before blowing it into the room; and the sterilization module sterilizes the air before delivering it into the room, improving air cleanliness. Generally, the functional module 200 is located at the lower part of the air supply equipment, while its air outlet can be located at the upper part of the casing 100. Correspondingly, a centrifugal fan component is provided at the upper part of the casing 100 to supply air to the room from the functional module 200. Alternatively, the air outlet of the functional module 200 can be located at the lower part of the casing 100, with the corresponding air outlet component also located at the lower part of the casing 100, allowing for independent operation of the lower part. Other modules can be installed at the upper part of the casing 100; for example, if the air supply equipment is configured as an air conditioner, a heat exchanger and a fan wheel can be installed at the upper part to achieve temperature regulation. In this embodiment, the functional module 200 is configured as a fresh air module, the air supply device is configured as an air conditioner, and the second panel 120 is used to open and close the cavity where the fresh air module is located so as to replace the filter components in the fresh air module. The air conditioner has a heat exchanger and a centrifugal fan wheel installed on the upper part of the casing 100. The fresh air module can supply air to the outside through the centrifugal fan wheel, or a separate centrifugal fan wheel can be installed on the lower part of the casing 100 to supply air to the room.

[0043] In one embodiment, please refer to Figures 3 to 5 The upper end of the second panel 120 is inserted into the lower edge of the first panel 110. It can be understood that when the second panel 120 opens and closes to cover the mounting opening 130, the upper end of the second panel 120 is connected to the lower edge of the first panel 110 via an insertion method. This ensures the connection stability between the second panel 120 and the first panel 110 and reduces interference with the smoothness of opening and closing the mounting opening 130. Thus, after the upper end of the second panel 120 is inserted into the lower edge of the first panel 110, the upper part of the second panel 120 is positioned to hang on the lower edge of the first panel 110, thereby overcoming the drooping effect of the second panel 120 due to its own weight and ensuring the stability of the gap between the second panel 120 and the first panel 110. Of course, in other embodiments, the upper end of the second panel 120 can also be connected to the first panel 110 via a hinge, allowing the second panel 120 to open and close the mounting opening 130 around its upper edge.

[0044] Furthermore, in this embodiment, please refer to Figures 3 to 5The second panel 120 has a connecting rib 123 at its upper end, and the first panel 110 has a connecting groove 113 at its lower edge. The connecting rib 123 is inserted into the connecting groove 113 along the opening direction of the mounting opening 130. The connecting rib 123 inserted into the connecting groove 113 forms a guiding fit structure, allowing the second panel 120 to smoothly complete the closing action along the original path during the closing process. This not only stabilizes the opening and closing of the mounting opening 130 but also effectively prevents the second panel 120 from shifting, misaligning, or jamming, improving the smoothness of user operation and the accuracy of closing. At the same time, the fit between the connecting rib 123 and the connecting groove 113 provides an upper and lower limit structure, allowing the second panel 120 to bear its own weight and remain stable in a hanging state. Furthermore, the sliding connection between the connecting rib 123 and the connecting groove 113 reduces the difficulty of opening and closing the mounting opening 130 of the second panel 120, ensuring a better user experience. Of course, in other embodiments, a connector groove 113 may be provided on the second panel 120, and a connector rib 123 may be provided on the lower edge of the first panel 110. The connector rib 123 and the connector groove 113 may be located inside the first panel 110 or the second panel 120, inside the housing 100, or they may be located outside the housing 100.

[0045] Regarding the horizontal stability of the first panel 110 and the connection stability of the first panel 110, in this embodiment, please refer to... Figure 1 , Figure 3 and Figure 5 The second panel 120 is provided with at least two insertion ribs 123, which are distributed on both horizontal sides of the second panel 120. It can be understood that by providing one insertion rib 123 on each horizontal side of the second panel 120, the second panel 120 can obtain a more balanced support force in the horizontal direction when connected to the first panel 110, helping to prevent the second panel 120 from tilting or wobbling during use. At the same time, the two insertion ribs 123 ensure that the second panel 120 can be positioned more accurately when the mounting opening 130 is closed, reducing the possibility of offset caused by the support of a single insertion rib 123, thereby improving the closing accuracy. The lengths of the two insertion ribs 123 can be similar, or they can be set according to the way the mounting opening 130 of the second panel 120 is opened and closed. For example, when the second panel 120 opens and closes the mounting opening 130 by rotating around the horizontal edge, the insertion rib 123 adjacent to the rotating side is shorter, and the insertion rib 123 farther from the rotating side is longer. Of course, in other embodiments, a connecting rib 123 may also be provided at the horizontal center of the second panel 120 to connect the upper horizontal center of the second panel 120 to the first panel 110.

[0046] In one embodiment, please refer to Figures 3 to 5The second panel 120 includes a panel body 121 and two connecting sub-plates 122 respectively connected to the horizontal sides of the panel body 121. The connecting sub-plates 122 and the panel body 121 are set at an angle. The insertion rib 123 extends inside the connecting sub-plate 122. The lower edge of the first panel 110 is provided with a downward protruding limiting rib 112. The insertion groove 113 is formed on the side opposite to the limiting rib 112 and the connecting sub-plate 122. It can be understood that the panel body 121 and the connecting sub-plates 122 on both sides form a U-shaped door-like structure. The angle between the connecting sub-plates 122 and the panel body 121 is generally an acute angle, which reduces the impact on the operation of the second panel 120 covering the mounting opening 130 in the opening direction of the mounting opening 130. Furthermore, the insertion rib 123 is located on the inner side of the connecting sub-plate 122 and extends therein. The insertion groove 113 is formed on the side of the limiting rib 112 facing the connecting sub-plate 122. Combined with the insertion rib 123 being inserted into the insertion groove 113 in the opening direction of the mounting opening 130, it can be understood that the insertion groove 113 is set through the limiting rib 112 on the side of the limiting rib 112 facing the connecting sub-plate 122. In this way, the limiting rib 112 provides a clear sliding path for the insertion process of the insertion rib 123, and provides a good guiding effect for the insertion process of the insertion rib 123 and the insertion groove 113, making the user's operation smoother and reducing the jamming phenomenon during the opening and closing of the mounting opening 130 of the second panel 120. Meanwhile, the lower edge of the second panel 120 is provided with limiting ribs 112 corresponding to the insertion ribs 123 on both horizontal sides. Insertion grooves 113 are opened on the opposite sides of the two limiting ribs 112. After the second panel 120 is covered by the mounting opening 130, the two connecting sub-plates 122 are in a state of clamping the two limiting ribs 112 on the horizontal side, thereby improving the connection stability between the upper end of the second panel 120 and the lower edge of the first panel 110. Of course, in other embodiments, a single-hole insertion groove 113 can also be opened on the lower edge of the first panel 110, and the single hole is set along the opening direction of the mounting opening 130. The insertion ribs 123 protrude from the inner side of the second panel 120 and are connected to the insertion groove 113 by plugging and unplugging.

[0047] In one embodiment, please refer to Figure 3 and Figure 5In the direction of the mounting opening 130, the vertical thickness of the insert rib 123 gradually increases, and the insert rib 123 is interference-fitted into the insert groove 113. It can be understood that in the direction away from the second panel 120, the vertical dimension of the insert groove 113 gradually decreases. Taking the insertion posture of the insert rib 123 into the insert groove 113 as a reference, at the same vertical position, the vertical thickness of the insert rib 123 is greater than the vertical dimension of the insert groove 113, presenting an interference fit between the insert rib 123 and the insert groove 113. Thus, during the process of the second panel 120 covering the mounting opening 130, the thinner part first enters the insert groove 113, gradually thickening as it goes deeper, forming a pressing transition from small to large, thereby achieving an interference fit, enhancing the friction between the insert rib 123 and the insert groove 113, and effectively preventing the second panel 120 from loosening or falling off due to vibration, gravity, or other reasons. Furthermore, initially, when the second panel 120 is placed over the mounting opening 130, the insertion slot 113 does not interfere with the movement of the insertion rib 123, facilitating the alignment and installation of the second panel 120. The insertion rib 123 can be positioned with its upper side horizontal and its lower side inclined downwards in the direction away from the functional module 200. Alternatively, the insertion rib 123 can be positioned with its upper side inclined upwards and its lower side inclined downwards in the direction away from the functional module 200. Or, the insertion rib 123 can have a certain curvature in its extension direction, exhibiting both an insertion relationship with the insertion slot 113 and a snap-fit ​​connection in the horizontal direction, thereby improving the stability of the second panel 120 relative to the first panel 110 in both horizontal and vertical directions. Of course, in other embodiments, a locking protrusion can be provided on the insertion rib 123, and a locking groove can be provided on the inner wall of the insertion slot 113. After the insertion rib 123 is inserted into the insertion slot 113, the locking protrusion and the locking groove cooperate to ensure the connection stability between the second panel 120 and the first panel 110.

[0048] Regarding the structural strength of the second panel 120, in one embodiment, please refer to... Figure 2 and Figure 3The inner side of the second panel 120 is also provided with a first reinforcing rib 124, which extends along the upper edge of the second panel 120. Since the upper edge of the second panel 120 and the lower edge of the first panel 110 are the main stress-bearing areas, the first reinforcing rib 124 is provided on the upper edge of the second panel 120 to improve its bending and torsional resistance, preventing warping, sagging, or even breakage of the upper edge due to long-term use. It also provides structural support for the insertion of the insertion rib 123 and the insertion groove, preventing plastic deformation or breakage at the location of the insertion rib 123 on the second panel 120, thereby ensuring the connection stability between the second panel 120 and the first panel 110. Simultaneously, while ensuring the structural strength of the second panel 120, the first reinforcing rib 124 can improve the flatness of the second panel 120, making the outer sides of the second panel 120 relatively consistent, thereby ensuring the overall appearance and aesthetics of the air supply equipment. Of course, in other embodiments, a reinforcing structure such as a metal rib can be embedded in the upper edge of the second panel 120 to ensure the structural strength of the upper edge of the second panel 120.

[0049] Furthermore, in this embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The first reinforcing rib 124 is connected to the end of the insertion rib 123 furthest from the functional module 200, and forms a first limiting step 125 with the insertion rib 123. The insertion opening of the insertion groove 113 abuts against the first limiting step 125. In conjunction with the above description of the insertion rib 123 extending along the inner side of the second panel 120, after the insertion rib 123 is inserted into the insertion groove 113, the first limiting step 125 abuts against the insertion opening of the insertion groove 113 to limit the insertion depth of the insertion rib 123, avoiding positioning deviations caused by excessive or insufficient insertion, and ensuring the accuracy and consistency of each operation of closing the mounting opening 130 of the second panel 120. Simultaneously, the first limiting step 125 provides an auxiliary support point for the insertion rib 123, helping to distribute the shear force and bending moment generated during insertion, reducing the possibility of breakage or deformation due to excessive stress concentration at the root of the insertion rib 123. Furthermore, the first reinforcing rib 124 and the connecting rib 123 are continuously arranged and both located at the upper edge of the second panel 120, thereby ensuring the structural strength of the upper edge of the second panel 120 and also enhancing the stability of the connection between the upper end of the second panel 120 and the first panel 110. Of course, in other embodiments, the connecting rib 123 may be disposed on the first reinforcing rib 124.

[0050] Regarding the mating relationship between the first reinforcing rib 124 and the first panel 110, in one embodiment, please refer to... Figure 1 , Figure 3 and Figure 4The lower edge of the first panel 110 forms a second limiting step 111, and the first reinforcing rib 124 abuts against the second limiting step 111. The outer side of the second panel 120 is flush with the outer side of the first panel 110. It can be understood that the second limiting step 111 acts as a mechanical stop, ensuring that each operation of closing the mounting opening 130 of the second panel 120 reaches the same position, improving closure consistency, and effectively preventing the second panel 120 from being inserted too deeply, which could cause interference with the functional module 200, uneven appearance of the air supply equipment, or deformation of the insertion structure. This improves the stability and durability of the second panel 120 during assembly and disassembly. Furthermore, the abutting relationship between the second limiting step 111 and the first reinforcing rib 124 can partially share the gravity load of the second panel 120, reduce the stress concentration phenomenon of the insertion rib 123, and enhance the anti-loosening ability of the second panel 120 after closing the mounting opening 130. This ensures the flatness of the appearance of the first panel 110 and the second panel 120, thereby improving the overall integrity of the air supply equipment and enhancing the connection stability between the second panel 120 and the first panel 110. Of course, in other embodiments, the lower edge of the first panel 110 may not be provided with the second limiting step 111 to ensure the size of the mounting opening 130; or, a groove may be formed on the second limiting step 111 to be configured with the first reinforcing rib 124, thereby improving the connection stability between the second panel 120 and the first panel 110.

[0051] Regarding the way the second panel 120 is connected to the mounting port 130, in one embodiment, please refer to... Figures 1 to 3 The second panel 120 is detachably mounted on the mounting opening 130. It is understood that the second panel 120 achieves a repeatedly detachable connection with the mounting opening 130 through methods such as plugging, snapping, and magnetic attraction. When the internal functional module 200 needs to be inspected or replaced, the user or technician can remove it without tools or with simple operation. This improves the convenience of cleaning, replacing, or upgrading the functional module 200. Regarding the force relationship between the second panel 120 and the first panel 110, it can be a plugging connection as described above, or a combination of magnetic attraction and hooking. Of course, in other embodiments, the second panel 120 can also maintain a fixed, movable connection between at least one edge and the housing 100, such as a louver, while the other edges are detachably connected, allowing it to open and close while covering the mounting opening 130.

[0052] Furthermore, in this embodiment, please refer to Figure 1 and Figure 3The second panel 120 is attached to the mounting opening 130 via magnetic attraction and / or plug-in connection. Alternatively, the upper edge of the second panel 120 may plug into the lower edge of the first panel 110, with other edges connected magnetically. Or, at least partially, the edges of the second panel 120 other than its upper edge may plug into the mounting opening 130. Alternatively, all edges of the second panel 120 may be magnetically connected to the periphery of the mounting opening 130, with the upper edge of the second panel 120 at least magnetically connected to the lower edge of the first panel 110. Thus, in the connection structure between the second panel 120 and the mounting opening 130, the magnetic structure allows for opening without manual rotation or pressing, and the plug-in structure supports quick insertion and removal, facilitating daily installation and removal of the second panel 120. Furthermore, the magnetic structure provides an "automatic suction feel," making opening and closing smoother, while the plug-in structure provides a "feeling of being in place," enhancing the user experience of installing and removing the second panel 120.

[0053] In one embodiment, for the second panel 120 and the mounting opening 130 to be connected by magnetic attraction, the second panel 120 is provided with first magnetic attraction portions 126 distributed on the horizontal side, and the housing 100 is provided with second magnetic attraction portions 140 at the horizontal edge of the mounting opening 130. The first magnetic attraction portions 126 and the second magnetic attraction portions 140 are magnetically attracted to each other. It can be understood that the magnetic attraction between the first magnetic attraction portions 126 and the second magnetic attraction portions 140 can provide a better closing force, making the second panel 120 more stable after the mounting opening 130 is closed, preventing loosening or accidental opening due to gravity or slight external force, thereby ensuring that the second panel 120 fits tightly against the periphery of the mounting opening 130 on the housing 100, reducing the contamination of the functional module 200 inside the housing 100 by external air, and ensuring the operational stability of the functional module 200. Thus, when the user approaches the closed position of the second panel 120, it automatically snaps into place without requiring force to press it. Opening the mounting port 130 is also relatively easy; simply applying appropriate pulling force is sufficient to release the magnetic fixation of the second panel 120, improving the user's operating experience. Specifically, a first magnetic suction part 126 is provided on the horizontal side of the second panel 120. Based on the above description of the interlocking between the second panel 120 and the first panel 110, it can be understood that the magnetic suction directions of the first magnetic suction part 126 and the second magnetic suction part 140, as well as the interlocking directions of the insertion rib 123 and the insertion groove 113, are consistent. This ensures the ease of assembling and disassembling the second panel 120 and also ensures the stability of the gap between the second panel 120 and the first panel 110 while stably covering the mounting port 130, improving the aesthetics of the air supply equipment. Of course, in other embodiments, the lower edge of the second panel 120 can also be magnetically connected to the lower periphery of the mounting port 130.

[0054] Specifically, in this embodiment, please refer to Figure 1 , Figure 3and Figure 4 The second magnetic suction part 140 includes a magnet part 141 adjacent to the upper part of the mounting port 130 and a fastener 142 adjacent to the lower part of the mounting port 130. The functional module 200 is connected to the housing 100 through the fastener 142. Alternatively, the second magnetic suction part 140 includes a magnet part 141 adjacent to the upper and lower parts of the mounting port 130. Alternatively, the second magnetic suction part 140 includes a fastener 142 adjacent to the upper and lower parts of the mounting port 130. The functional module 200 is connected to the housing 100 through the fastener 142. It is understood that the first magnetic attraction part 126 is also provided on the upper and lower parts of the second panel 120. In this way, the first magnetic attraction part 126 and the second magnetic attraction part 140 can achieve force balance at both ends of the vertical of the second panel 120. Combined with the second magnetic attraction part 140 being distributed on both sides of the mounting opening 130 and the first magnetic attraction part 126 being distributed on both sides of the second panel 120, the first magnetic attraction part 126 and the second magnetic attraction part 140 form a connection relationship on the housing 100 at the four corners of the second panel 120, thereby ensuring the stability of the second panel 120 on the housing 100. In the case where the second magnetic attraction part 140 at the lower part of the mounting port 130 is a fastener 142, the fastener 142 is configured as a galvanized screw or other metal screw and has magnetization capability. That is, at least one of the first magnetic attraction part 126 and the second magnetic attraction part 140 is a magnet or electromagnet, so that the first magnetic attraction part 126 and the second magnetic attraction part 140 have the ability to attract each other. Combined with the fastener 142 to fix the functional module 200 to the housing 100, the need for additional magnets for fixing the second panel 120 is reduced, saving space and cost. It should be noted that for the structure of the magnet part 141, the first magnetic attraction part 126, etc., a limiting bracket is provided on the housing 100 or the second panel 120. The limiting bracket limits the magnet in the mounting direction of the second panel 120, and the magnet is installed horizontally in the limiting bracket.

[0055] In one embodiment, please refer to Figure 2 and Figure 3The second panel 120 also has a second reinforcing rib 127 on its inner side, which extends along the lower edge of the second panel 120. The housing 100 has a recessed clearance groove 150 corresponding to the lower part of the mounting opening 130, and the second reinforcing rib 127 is fitted into the clearance groove 150. Referring to the above description of the first reinforcing rib 124, the second reinforcing rib 127 enhances the structural strength of the second panel 120 at its lower edge, preventing deformation or breakage caused by frequent opening and closing, handling vibration, or material aging. It also forms a force balance with the upper edge of the second panel 120, thereby ensuring the structural stability of the second panel 120. The clearance groove 150 provides a space for the second reinforcing rib 127, allowing the second panel 120 to maintain a vertical posture after being placed over the mounting opening 130, thus reducing the force between the second panel 120 and the first panel 110. This ensures the connection stability between the second panel 120 and the first panel 110 while also maintaining the overall appearance and aesthetics of the air supply equipment. The clearance groove 150 and the second reinforcing rib 127 are in an abutting relationship. Either the side wall of the clearance groove 150 abuts against the second reinforcing rib 127, or the bottom wall of the clearance groove 150 abuts against the second reinforcing rib 127. This provides support for the vertical force on the second panel 120, thereby balancing the force distribution of the second panel 120 around the mounting opening 130 and improving the installation stability of the second panel 120.

[0056] Regarding the force relationship between the horizontal side of the second panel 120 and the mounting opening 130, in one embodiment, please refer to... Figures 1 to 3 The inner side of the second panel 120 is also provided with a limiting buckle 128, which is distributed on the horizontal side of the second panel 120 and engages with the inner periphery of the mounting opening 130. Without loss of generality, the housing 100 is provided with a protrusion corresponding to the inner periphery of the mounting opening 130, and the limiting buckle 128 has a portion spaced from the inner side of the second panel 120. After the second panel 120 is closed on the mounting opening 130, the limiting buckle 128 engages with the protrusion on the inner periphery of the mounting opening 130, thereby forming a horizontal force balance on the horizontal side of the second panel 120, enhancing the closing stability of the second panel 120 when it is closed on the mounting opening 130, and reducing the probability of the second panel 120 accidentally opening the mounting opening 130 due to gravity, vibration or misoperation. Of course, in other embodiments, an abutment buckle can be provided on the mounting opening 130, and an abutment protrusion can be provided on the inner side of the second panel 120. After the second panel 120 is covered on the mounting opening 130, the abutment buckle abuts against the abutment protrusion, thereby forming a limiting effect between the second panel 120 and the mounting opening 130 in the horizontal direction.
