Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to a panel assembly and a fresh air device. Background Technology

[0002] A fresh air system is an effective air conditioning device that can expel stale indoor air to the outside and bring in fresh outdoor air, ensuring that the room is always filled with fresh air.

[0003] In related technologies, air vents are set on multiple side walls of the fresh air equipment, and the air vents on multiple side walls are directly connected to each other, so as to increase the air intake of the fresh air equipment and improve the user's comfort.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The air vents on multiple side walls are directly connected. After the multiple air vents are connected, their shape is no longer regular, making it difficult to set up air flaps to open or close the air vents. As a result, the air vents are set to be in a normally open state, which makes it easy for dust and other particles to enter the fresh air equipment through the air vents.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a panel assembly and a fresh air device to solve the problem in related technologies where the air vents are always open, causing dust and other substances to easily enter the fresh air device through the air vents.

[0009] According to a first aspect of the present invention, a panel assembly is provided, comprising: a panel surrounding an air outlet cavity, the sidewalls of the panel including a first sidewall and a second sidewall, the first sidewall and the second sidewall being connected and forming an angle at the connection point, the first sidewall having a first air inlet / outlet, the second sidewall having a second air inlet / outlet, both the first air inlet / outlet and the second air inlet / outlet communicating with the air outlet cavity; a grille movably disposed at the first air inlet / outlet to open or close the first air inlet / outlet; and an air guide plate movably disposed at the second air inlet / outlet to open or close the second air inlet / outlet.

[0010] Optionally, the first sidewall is the top wall of the panel, and the second sidewall is located below the first sidewall; or the first sidewall is the bottom wall of the panel, and the second sidewall is located above the first sidewall.

[0011] Optionally, there are two second sidewalls, which are arranged opposite to each other. One second sidewall is connected to one end of the first sidewall along its length and the connection point forms an angle, while the other second sidewall is connected to the other end of the first sidewall along its length and the connection point forms an angle.

[0012] Optionally, the air guide plate is rotatably connected to the panel to open or close the second air inlet / outlet.

[0013] Optionally, the panel assembly also includes a wheel, which is driven to rotate the air guide plate, thereby causing the air guide plate to rotate relative to the panel.

[0014] Optionally, the wheel may be at least partially exposed on the panel.

[0015] Optionally, the surface of the wheel has a textured surface.

[0016] Optionally, the concave-convex structure includes multiple grooves arranged sequentially along the circumference of the rotating wheel; the panel is provided with positioning posts, and when the rotating wheel is rotated, the positioning posts are sequentially inserted into their corresponding grooves; or

[0017] The concave-convex structure includes multiple protruding posts, which are arranged sequentially along the circumference of the rotating wheel; the panel is provided with a positioning groove, and when the rotating wheel is rotated, the protruding post corresponding to the positioning groove is inserted into the positioning groove.

[0018] Optionally, the panel is provided with a limiting part, which cooperates with the rotating wheel to limit the movement of the rotating wheel relative to the limiting part along the axial direction of the rotating wheel.

[0019] According to a second aspect of the present invention, a fresh air device is provided, comprising: a panel assembly as described in any of the above embodiments; and an outer tube disposed on the panel and communicating with the air cavity.

[0020] The panel assembly and fresh air device provided in this disclosure can achieve the following technical effects:

[0021] A first air inlet and a second air outlet are respectively provided on the first side wall and the second side wall. When the first air inlet and the second air outlet are used as air inlets, the air intake volume of the fresh air equipment can be increased to improve user satisfaction; when the first air inlet and the second air outlet are used as air outlets, the air outlet area of ​​the fresh air equipment can be increased and the gentleness of the air outlet can be improved to improve user satisfaction.

[0022] The junction of the first and second sidewalls forms an angle, resulting in angles at both the first and second air inlets / outlets. A grille is installed at the first air inlet / outlet to open or close it, preventing it from being normally open. A guide vane is installed at the second air inlet / outlet to open or close it, also preventing it from being normally open.

[0023] The first air inlet / outlet is opened and closed via a grille, while the second air inlet / outlet is opened and closed via a guide vane. Due to the different structures of the grille and the guide vane, their motion parameters, such as motion form or amplitude, differ when the grille opens or closes the first air inlet / outlet and when the guide vane opens or closes the second air inlet / outlet. This allows for better utilization of the panel space during their movement and avoids interference that would occur if their motion parameters were identical.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0047] Combination Figure 1-7 As shown, this disclosure provides a panel assembly for a fresh air system.

[0048] The panel assembly includes panel 10, grille 20 and air guide plate 30.

[0049] like Figure 1As shown, panel 10 surrounds air outlet cavity 118. Panel 10 includes front panel 111 and rear panel 112, which together surround air outlet cavity 118. The sidewalls of panel 10 include first sidewall 101 and second sidewall 106. First sidewall 101 and second sidewall 106 are connected and the connection point forms an angle. First sidewall 101 is provided with first air inlet / outlet 102, and second sidewall 106 is provided with second air inlet / outlet 113. Both first air inlet / outlet 102 and second air inlet / outlet 113 are connected to air outlet cavity 118.

[0050] The fresh air system includes a panel assembly, an outer duct 50, a heat exchange core, and a fan.

[0051] The outer duct 50 is located on the panel 10 and is connected to the air cavity 118, for example... Figure 1 In the middle, the outer tube 50 is connected to the rear plate 112. The fan and the heat exchange core are both located in the outer tube 50. The heat exchange core is used to exchange heat with the air flowing through the outer tube 50. Driven by the fan, air enters the outer tube 50 through the end of the outer tube 50 away from the air chamber 118, and flows out through the first air inlet / outlet 102 and / or the second air inlet / outlet 113. Alternatively, driven by the fan, air enters the air chamber 118 and the outer tube 50 in sequence through the first air inlet / outlet 102 and / or the second air inlet / outlet 113, and then flows out through the end of the outer tube 50 away from the air chamber 118.

[0052] The wall has a through hole, through which the outer tube 50 passes.

[0053] The panel 10 is located indoors. The first air inlet / outlet 102 and the second air inlet / outlet 113 are both connected to the indoor environment. The end of the outer pipe 50 away from the air cavity 118 is connected to the outside. Driven by the fan, outdoor air flows out to the indoor environment through the outer pipe 50, the air cavity 118, the first air inlet / outlet 102 and / or the second air inlet / outlet 113, or indoor air flows into the outside environment through the first air inlet / outlet 102 and / or the second air inlet / outlet 113, the air cavity 118, and the outer pipe 50.

[0054] Alternatively, panel 10 can be located outdoors, with the first air inlet / outlet 102 and the second air inlet / outlet 113 both connected to the outdoors, and the end of the outer pipe 50 away from the air chamber 118 connected to the indoors. Driven by the fan, indoor air flows out to the outdoors through the first air inlet / outlet 102 and / or the second air inlet / outlet 113, the outer pipe 50, and the air chamber 118, or outdoor air flows into the indoors through the air chamber 118, the outer pipe 50, the first air inlet / outlet 102 and / or the second air inlet / outlet 113.

[0055] like Figure 3 As shown, the grille 20 is movably disposed at the first air inlet / outlet 102 to open or close the first air inlet / outlet 102.

[0056] like Figure 1As shown, the air guide plate 30 is movably disposed at the second air inlet / outlet 113 to open or close the second air inlet / outlet 113.

[0057] A first air inlet / outlet 102 and a second air inlet / outlet 113 are respectively provided on the first side wall 101 and the second side wall 106. When the first air inlet / outlet 102 and the second air inlet / outlet 113 are used as air inlets, the air intake volume of the fresh air equipment can be increased to improve user satisfaction; when the first air inlet / outlet 102 and the second air inlet / outlet 113 are used as air outlets, the air outlet area of ​​the fresh air equipment can be increased and the gentleness of the air outlet can be improved to improve user satisfaction.

[0058] The connection between the first sidewall 101 and the second sidewall 106 forms an angle, resulting in angles also existing at the first air inlet / outlet 102 and the second air inlet / outlet 113. A grille 20 is provided at the first air inlet / outlet 102 to open or close it, preventing it from being normally open. A guide vane 30 is provided at the second air inlet / outlet 113 to open or close it, preventing it from being normally open.

[0059] The first air inlet / outlet 102 is opened and closed via a grille 20, while the second air inlet / outlet 113 is opened and closed via a guide vane 30. Due to the different structures of the grille 20 and the guide vane 30, their motion parameters, such as motion form or amplitude, differ when the grille 20 opens or closes the first air inlet / outlet 102 and the guide vane 30 opens or closes the second air inlet / outlet 113. This allows for better utilization of the space on the panel 10 during their movement, avoiding interference that would occur if their motion parameters were identical. Furthermore, it enables independent control of the first air inlet / outlet 102 and the second air inlet / outlet 113. This design not only increases the flexibility of controlling the opening and closing of the first air inlet / outlet 102 and the second air inlet / outlet 113 but also allows for adjustment of their opening and closing states according to actual needs.

[0060] like Figure 3 As shown, the grille 20 includes a grille body 201 and an operating part 203. The grille body 201 is movably disposed at the first air inlet / outlet 102 so as to move relative to the panel 10 between an open position corresponding to the first air inlet / outlet 102 and a closed position offset from the first air inlet / outlet 102.

[0061] The operating part 203 is connected to the grille body 201 and exposed on the panel 10. Operating the operating part 203 causes the grille body 201 to move between the open position and the closed position relative to the panel 10.

[0062] In the open position, the vent 202 corresponds to the first air inlet / outlet 102 to open the first air inlet / outlet 102; in the closed position, the vent 202 is offset from the first air inlet / outlet 102 to close the first air inlet / outlet 102. By providing the movable grille 20, flexible control over the opening and closing of the first air inlet / outlet 102 is achieved.

[0063] like Figure 4 and Figure 5 As shown, the first air inlet / outlet 102 includes multiple sub-air inlets 103. The number of sub-air inlets 103 is multiple, and the number of ventilation outlets 202 is equal to and corresponds one-to-one with the number of sub-air inlets 103. The multiple sub-air inlets 103 are arranged sequentially along the length of the first sidewall 101. In the open position, each ventilation outlet 202 corresponds to its corresponding sub-air inlet 103, and each sub-air inlet 103 is open; in the closed position, each ventilation outlet 202 is offset from its corresponding sub-air inlet 103, and each sub-air inlet 103 is closed. Figures 3 to 5 In the middle, the grille is in the closed position.

[0064] Users can easily switch the grille 20 between open and closed positions by operating the control part 203 of the extended panel 10, thereby opening and closing the first air inlet and outlet. This design enhances the user interactivity of the panel assembly, allowing users to manually and quickly adjust the ventilation status of the first air inlet and outlet 102 as needed. This eliminates the need for a drive mechanism, reducing the cost of the fresh air system and improving its reliability.

[0065] Optionally, the grille body 201 slides relative to the first air inlet / outlet 102.

[0066] Compared to other motion methods (such as rotation or oscillation), the sliding design has lower frictional resistance and higher motion precision, which can effectively reduce the jamming or wear problems that may occur during the movement of the grille 20, and extend the service life of the panel assembly.

[0067] The first air inlet / outlet 102 extends along the length of the first sidewall 101, and the grille body 201 extends along the length of the first air inlet / outlet 102. The sliding direction of the grille 20 relative to the panel 10 is the extension direction of the grille 20. Figure 3 Left and right directions.

[0068] It's understandable that the grille can also rotate relative to the panel.

[0069] Optionally, the grille 20 also includes a positioning part, and the panel 10 is provided with a positioning engagement part. In the open position and / or closed position, the positioning part engages with the positioning engagement part to restrict the movement of the grille 20 relative to the panel 10.

[0070] By incorporating a positioning part and a positioning mating part, the grille 20 is stably fixed in the open and / or closed positions, preventing it from moving relative to the panel 10. This design effectively prevents the grille 20 from accidentally moving due to external forces or vibrations during use, ensuring that the opening and / or closing state of the first air inlet / outlet 102 remains stable, thus improving the reliability and safety of the panel assembly.

[0071] Optionally, the positioning part includes a first sub-positioning part 204 and a second sub-positioning part 206, which are arranged sequentially along the direction from the open position to the closed position. In the closed position, the first sub-positioning part 204 cooperates with the positioning mating part to restrict the movement of the grille 20 relative to the panel 10. In the open position, the second sub-positioning part 206 cooperates with the positioning mating part to restrict the movement of the grille 20 relative to the panel 10.

[0072] By setting the first sub-positioning part 204 and the second sub-positioning part 206, which cooperate with the positioning mating part in the closed position and the open position respectively, the grille 20 can be positioned in both the closed and open positions, which further enhances the stability of the grille 20, ensures that it can maintain a precise position in both the closed and open positions, and improves the accuracy and reliability of the panel assembly.

[0073] Optionally, in the open or closed position, the positioning mating part is limited to between the first sub-positioning part 204 and the second sub-positioning part 206.

[0074] This arrangement ensures that, in the open or closed position, the positioning mating part is clamped between the first sub-positioning part 204 and the second sub-positioning part 206, thereby limiting the movement of the positioning mating part towards the first sub-positioning part 204 and towards the second sub-positioning part 206, further enhancing the stability of the grille 20 in the open or closed position. This design effectively prevents the grille 20 from shifting due to external forces or vibrations in the open or closed position, improving the accuracy of position control of the grille 20.

[0075] When the locating part is in the open position and is limited between the first sub-locating part 204 and the second sub-locating part 206, the locating part is limited between the grille body 201 and the first sub-locating part 204 in the closed position, thus restricting the reciprocating movement of the grille 20 along the length direction of the first sidewall 101 when in the closed position; when the locating part is in the closed position and is limited between the first sub-locating part 204 and the second sub-locating part 206, the locating part is limited between the grille body 201 and the second sub-locating part 206 in the open position, thus restricting the reciprocating movement of the grille 20 along the length direction of the first sidewall 101 when in the open position.

[0076] Optionally, the panel 10 is provided with a first through hole, through which the operating part 203 extends out of the panel 10.

[0077] The positioning part is located in the operating part 203, and the positioning mating part includes the wall of the first through hole.

[0078] By having the operating part 203 protrude through the first through hole of the panel 10, the operating part 203 is exposed on the panel 10, allowing the operator to hold the operating part 203 while sliding the grille 20. A positioning part is also positioned on the operating part 203, with the wall of the first through hole serving as a positioning mating part, simplifying the structural design of the panel assembly. This design not only reduces the number and complexity of parts, lowering production costs, but also makes the overall appearance of the panel assembly more concise and aesthetically pleasing, while ensuring the positioning function of the grille 20 in both open and closed positions.

[0079] Optionally, such as Figure 5 As shown, the positioning part includes a first positioning protrusion 205 and a second positioning protrusion 207, which are arranged sequentially along the direction from the open position to the closed position. The first sub-positioning part includes the first positioning protrusion, and the second sub-positioning part includes the second positioning protrusion.

[0080] In the closed position, the first positioning protrusion 205 abuts against the wall of the first through hole to restrict the movement of the grille 20 relative to the panel 10; in the open position, the wall of the first through hole is confined between the first positioning protrusion 205 and the second positioning protrusion 207 to restrict the movement of the grille 20 relative to the panel 10.

[0081] The grille body 201, the first positioning protrusion 205, and the second positioning protrusion 207 are arranged in sequence.

[0082] like Figure 5 As shown, in the closed position, the wall of the first through hole is limited between the grille body 201 and the first positioning protrusion 205. That is, the wall of the first through hole facing the grille body 201 abuts against the grille body 201, and the wall of the first through hole facing the first positioning protrusion 205 abuts against the first positioning protrusion 205, so as to restrict the reciprocating movement of the grille 20 along the line connecting the grille body 201 and the first positioning protrusion 205.

[0083] In the open position, the wall of the first through hole is limited between the first positioning protrusion 205 and the second positioning protrusion 207, that is, the wall of the first through hole facing the first positioning protrusion 205 abuts against the first positioning protrusion 205, and the wall of the first through hole facing the second positioning protrusion 207 abuts against the second positioning protrusion 207, so as to restrict the reciprocating movement of the grille 20 along the line connecting the first positioning protrusion 205 and the second positioning protrusion 207.

[0084] Optionally, the positioning mating part includes a first sub-positioning mating part and a second sub-positioning mating part, which are arranged sequentially along the direction from the open position to the closed position.

[0085] In the closed position, the positioning part engages with the first sub-positioning engagement part to restrict the movement of the grille 20 relative to the panel 10; in the open position, the positioning part engages with the second sub-positioning engagement part to restrict the movement of the grille 20 relative to the panel 10.

[0086] By setting the first sub-positioning mating part and the second sub-positioning mating part, two different mating positions are provided for the positioning part, which correspond to the open position and the closed position of the grille 20, respectively.

[0087] Optionally, the panel 10 is provided with a second through hole, and the grille 20 also includes a mounting portion 208.

[0088] The mounting part 208 is located on the side of the grille body 201 away from the operation part 203, and the mounting part 208 extends through the second through hole.

[0089] When installing the grille 20, insert the mounting part 208 into the second through hole and insert the mounting part 208 all the way into the second through hole along the length of the grille 20, such as... Figure 3 As shown, insert the mounting part 208 all the way to the left, and insert the operating part 203 into the first through hole. Press the mounting part 208 in the opposite direction to the insertion of the mounting part 208 into the second through hole, i.e. Figure 3 As shown, when the mounting part 208 is pressed to the right, the first positioning protrusion 205 and the second positioning protrusion 207 pass through the first through hole. The hole wall of the first through hole is limited between the grille body 201 and the first positioning protrusion 205. At this time, the grille 20 is in the open or closed position. Taking the grille 20 being in the closed position as an example, when it is necessary to put the grille 20 in the open position, the operating part 203 is pressed to the left. The first positioning protrusion 205 passes through the hole wall of the first through hole. When the hole wall of the first through hole is limited between the first positioning protrusion 205 and the second positioning protrusion 207, the grille 20 is in the open position.

[0090] The mounting section 208, the grille body 201, and the operating section 203 can be an integrated structure or a separate structure that is fixedly connected to each other.

[0091] Optionally, such as Figure 1 As shown, the first sidewall 101 is the top wall of the panel 10, and the second sidewall 106 is located below the first sidewall 101 to realize the top air intake and exhaust and the side air intake and exhaust of the panel 10.

[0092] Optionally, the first sidewall 101 is the bottom wall of the panel 10, and the second sidewall 106 is located above the first sidewall 101 to realize the bottom air inlet and outlet and the side air inlet and outlet of the panel 10.

[0093] Optionally, such as Figure 6 As shown, there are two second sidewalls 106, which are arranged opposite to each other. One of the second sidewalls 106 is connected to one end of the first sidewall 101 along its length and the connection point forms an angle. The other second sidewall 106 is connected to the other end of the first sidewall 101 along its length and the connection point forms an angle.

[0094] The two second sidewalls 106 are connected to the two ends of the first sidewall 101 along its length, forming an angled structure. This design not only makes the panel assembly more symmetrical and aesthetically pleasing, but also provides ventilation at both second sidewalls 106, increasing the selectivity of ventilation paths. At the same time, this structure also makes the panel assembly more stable during installation and use, better adapting to different installation spaces and usage requirements.

[0095] Panel 10 also includes a third sidewall 107, with the first sidewall 101 connected between one end of two opposing second sidewalls 106 and the third sidewall 107 connected between the other ends of two opposing second sidewalls 106, the first sidewall 101 and the third sidewall 107 being arranged opposite to each other.

[0096] Optionally, such as Figure 6 As shown, the air guide plate 30 is rotatably connected to the panel 10 to open or close the second air inlet / outlet 113.

[0097] The air guide plate 30 is rotatably connected to the panel 10, allowing the air guide plate 30 to flexibly open or close the second air inlet / outlet 113. This rotatable connection method is simple and convenient to operate. Users can easily adjust the opening and closing state of the first air inlet / outlet 102 by rotating the air guide plate 30, improving the ease of use of the panel assembly. At the same time, compared with other connection methods (such as sliding connection), the rotatable connection method has higher stability and reliability, which can effectively reduce wear and malfunctions of the air guide plate 30 during use and extend the service life of the panel assembly.

[0098] One of the air guide plate 30 and the panel 10 is provided with a rotating shaft 302, and the other is provided with a shaft hole. The rotating shaft 302 is inserted into the shaft hole. Alternatively, both the air guide plate 30 and the panel 10 are provided with shaft holes, and the rotating shaft 302 passes through the shaft holes on the air guide plate 30 and the panel 10. The rotating shaft 302 is adapted to the shaft hole and can rotate relative to the shaft hole.

[0099] The surface of the air guide plate 30 facing the air cavity 118 is provided with a first mounting protrusion 301, and the inner wall surface of the panel 10 is provided with a second mounting protrusion 108. The shaft hole or rotating shaft 302 on the air guide plate 30 is located on the first mounting protrusion 301, and the shaft hole or rotating shaft 302 on the panel 10 is located on the second mounting protrusion 108.

[0100] It's understandable that the air guide plate can also be slidably connected to the panel.

[0101] Optionally, such as Figure 6 As shown, the panel assembly also includes a rotating wheel 40, which is driven to connect with the air guide plate 30. Rotating the rotating wheel 40 causes the air guide plate 30 to rotate relative to the panel 10.

[0102] By connecting the rotating wheel 40 to the air guide plate 30, manually rotating the rotating wheel 40 can drive the air guide plate 30 to rotate relative to the panel 10, thereby opening or closing the second air inlet / outlet 113. This design not only improves the convenience and accuracy of operation but also makes the overall structure of the panel assembly more compact and aesthetically pleasing. Simultaneously, the rotating wheel 40 provides a stable driving force for the rotation of the air guide plate 30, ensuring its smoothness and reliability during rotation.

[0103] Optionally, the wheel 40 is at least partially exposed outside the panel 10.

[0104] The panel 10 is provided with a third through hole 114, and the rotating wheel 40 is located in the second through hole and partially protrudes outward from the third through hole 114. The direction closer to the air cavity 118 is the inside, and the direction farther away from the air cavity 118 is the outside.

[0105] The rotary wheel 40 is at least partially exposed on the panel 10, allowing users to directly operate the exposed portion of the rotary wheel 40 to control the rotation of the air guide plate 30. This design not only improves operational convenience but also allows users to intuitively see the rotation status of the rotary wheel 40, enhancing the interactivity between the user and the panel assembly. Simultaneously, the exposed portion of the rotary wheel 40 can also serve as a decorative element of the panel assembly, improving its overall aesthetics.

[0106] Optionally, such as Figure 7 As shown, the surface of the rotating wheel 40 is provided with a concave-convex structure 401.

[0107] The surface of the rotating wheel 40 is provided with a concave-convex structure 401. When the user places their hand on the concave-convex structure 401 to rotate the wheel 40, the friction between the user and the wheel 40 is increased, improving the operating feel. This design allows the user to apply force more easily when rotating the wheel 40, reducing the possibility of slippage and improving the accuracy and stability of operation. At the same time, the concave-convex structure 401 also provides a certain degree of anti-slip effect, further enhancing the safety of using the wheel 40.

[0108] Optionally, the concave-convex structure 401 is formed in a sawtooth shape, and the sawtooth shape is arranged sequentially along the circumference of the rotating wheel 40.

[0109] like Figure 7As shown, the concave-convex structure 401 includes multiple grooves 402, which are arranged sequentially along the circumference of the rotating wheel 40; the panel 10 is provided with positioning posts 110, such as... Figure 7 The middle and rear plate is provided with positioning posts. When the rotating wheel 40 is rotated, the positioning post 110 can move relative to the groove 402 between the insertion position in the groove 402 and the disengagement position in the groove 402, so that the positioning post 110 is inserted into the groove 402 corresponding to it in turn.

[0110] By setting multiple grooves 402 arranged sequentially along the circumference of the rotating wheel 40, and cooperating with the positioning post 110 on the panel 10, precise control of the rotation position of the air guide plate 30 is achieved. The positioning post 110 can move between the insertion position into the groove 402 and the disengagement position out of the groove 402. The positioning post 110 is adapted to the groove 402, so that the positioning post 110 can limit the groove 402. This design allows the air guide plate 30 to be stably fixed in different positions, avoiding accidental rotation caused by external force or vibration, and improving the reliability and stability of the panel assembly.

[0111] Alternatively, the concave-convex structure 401 includes multiple protrusions, which are arranged sequentially along the circumference of the rotating wheel 40; the panel 10 is provided with a positioning groove, and when the rotating wheel 40 is rotated, the protrusion corresponding to the positioning groove is inserted into the positioning groove.

[0112] By setting multiple protrusions arranged sequentially along the circumference of the rotating wheel 40, and cooperating with the positioning grooves on the panel 10, precise control of the rotation position of the air guide plate 30 is achieved. The protrusion corresponding to the positioning groove can be inserted into the positioning groove. As the rotating wheel 40 rotates, the protrusion disengages from the positioning groove, and another protrusion corresponding to the positioning groove inserts into the positioning groove. The positioning groove and the protrusion are adapted to each other, so that the positioning groove can limit the protrusion. This design allows the air guide plate 30 to be stably fixed in different positions, avoiding accidental rotation caused by external forces or vibrations, and improving the reliability and stability of the panel assembly.

[0113] Optionally, such as Figure 6 As shown, panel 10 is provided with a limiting part, which cooperates with the rotating wheel 40 to limit the movement of the rotating wheel 40 relative to the limiting part along the axial direction of the rotating wheel 40.

[0114] By providing a limiting part on the panel 10 and having it cooperate with the rotor 40, the axial movement of the rotor 40 is restricted. This design effectively prevents the rotor 40 from axial displacement due to external forces or vibrations during use, ensuring that the rotor 40 always maintains a stable driving connection with the air guide plate 30. At the same time, the setting of the limiting part also improves the overall structural stability of the panel assembly and extends its service life.

[0115] The limiting part includes a first limiting protrusion 115 and a second limiting protrusion 116. The first limiting protrusion 115 and the second limiting protrusion 116 are arranged opposite to each other and sequentially arranged along the axial direction of the rotating wheel 40, together defining a limiting space 117. The rotating wheel 40 is limited within the limiting space 117 to restrict the movement of the rotating wheel 40 along the axial direction.

[0116] Alternatively, the limiting part can be a buckle or a slot, with the rotating wheel 40 engaging with the air guide plate 30.

[0117] The rotor 40 is fixedly connected to the air guide plate 30.

[0118] The air guide plate 30 is provided with a connecting shaft 303. The cross-section of the connecting shaft 303 is non-circular and is adapted to the center hole of the rotating wheel 40. The connecting shaft 303 is inserted into the center hole of the rotating wheel 40 to prevent the rotating wheel 40 from moving relative to the air guide plate 30.
