Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a ventilation device. Background Technology

[0002] Currently, dust accumulates on the mesh components of air supply devices, which can easily lead to poor air quality. Therefore, the mesh components need to be disassembled for cleaning. However, the disassembly and assembly process of air supply devices in related technologies is quite complex, resulting in time-consuming and labor-intensive disassembly of the mesh components. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the present invention provides an air supply device.

[0005] In view of this, the present invention proposes an air supply device, comprising: a body, wherein a driving component is disposed within the body; a fan blade assembly connected to the driving component, the driving component being used to drive the fan blade assembly to rotate; and a mesh cover assembly detachably connected to the body, the mesh cover assembly comprising a first cover and a second cover, wherein an opening is provided on one side of the first cover, the second cover is disposed at the opening, and at least a portion of the second cover is movably connected to the first cover to open or close the opening; wherein, when the second cover closes the opening, the mesh cover assembly is connected to the body through the second cover, and the fan blade assembly is located inside the mesh cover assembly; when the second cover opens the opening, the second cover can be separated from the body.

[0006] The air supply device provided by this invention includes a body, a fan blade assembly, and a guard assembly. A drive component is disposed within the body, and the fan blade assembly is connected to the drive component. The drive component can drive the fan blade assembly to rotate, thereby realizing the air supply function of the air supply device. The guard assembly includes a first guard and a second guard. The second guard is disposed at the opening of the first guard, and at least a portion of the second guard is movable relative to the first guard, allowing the second guard to open or close the opening. When the second guard is closed, the guard assembly is connected to the body via the second guard, thus enabling the installation of the guard assembly. In this case, the fan blade assembly is located within the guard assembly, and the guard assembly provides protection for the fan blade assembly. With the second cover opening, the second cover separates from the main body, allowing the entire cover assembly to be separated from the main body, thus enabling the disassembly of the mesh assembly from the main body. At the same time, with the opening open, the fan blade assembly can be moved out of the first cover, so the user can disassemble the mesh assembly without removing the fan blade assembly, which is convenient, quick, and easy to clean. In addition, after the mesh assembly is removed, it is easy to disassemble and clean the fan blade assembly.

[0007] The air supply device provided by the present invention may also have the following additional technical features:

[0008] In some technical solutions, optionally, the second cover includes: a first baffle, disposed at the opening and connected to the first cover; and a second baffle, disposed at the opening, connected to the first cover, and disposed opposite to the first baffle, wherein at least one of the first baffle and the second baffle is closably connected to the first cover to open or close the opening; when the first baffle and the second baffle close the opening, the first baffle and the first cover enclose an installation port, and the mesh assembly is installed on the machine body through the installation port.

[0009] In this technical solution, the second cover includes a first baffle and a second baffle, both of which are connected to the first cover. At least one of the first and second baffles is movably connected to the first cover, allowing the first and second baffles to open or close the opening. When the opening is closed, the first and second baffles fit together at the opening, forming an installation port, allowing the second cover to be installed on the machine body through the installation port, thus installing the mesh assembly. When the opening is open, the first and second baffles separate, allowing the fan blade assembly to be removed from the first cover through the opening, thus achieving the overall disassembly of the mesh assembly.

[0010] In some technical solutions, optionally, at least one of the first baffle and the second baffle is rotatably connected to the first cover, so that at least one of the first baffle and the second baffle can be flipped outward of the first cover to open an opening.

[0011] In this technical solution, at least one of the first baffle and the second baffle is rotatably connected to the first cover, allowing the first baffle and the second baffle to flip outwards to open the opening. At the same time, the first baffle and the second baffle are disengaged, preventing them from enclosing the mounting opening used for limiting the position. Consequently, the mesh assembly can be separated from the machine body through the opening. When at least one of the first baffle and the second baffle rotates to the position of closing the opening, the first baffle and the second baffle are joined at the opening, thereby enclosing the mounting opening and connecting the mesh assembly to the machine body.

[0012] In some technical solutions, optionally, at least one of the first baffle and the second baffle is provided with a first limiting member, and the first baffle and the second baffle are fixed to the first cover by the first limiting member.

[0013] In this technical solution, at least one of the first baffle and the second baffle is provided with a first limiting member, so that the first baffle and the second baffle can be connected with the first cover, and the first baffle and the second baffle are kept in the closed opening state.

[0014] In some technical solutions, optionally, a second limiting member is provided on the first cover, and the first limiting member can be limited and cooperated with the second limiting member; or the first limiting member is rotatably provided on the side of the first baffle or the second baffle away from the first cover, for locking the first baffle and the second baffle when the opening of the first baffle and the second baffle are closed.

[0015] In this technical solution, a second limiting member is provided on the first cover. Through the limiting cooperation between the first and second limiting members, the connection between the first baffle and the first cover is achieved, ensuring the reliability of the first and second baffles in closing the opening. Alternatively, the first limiting member is rotatably disposed on the first or second baffle, and the first limiting member is located on the side opposite to the first cover. When the first and second baffles are closed, the first limiting member locks the first and second baffles together, preventing the first and second baffles from opening.

[0016] Optionally, the first limiting member is rotatable between a first state and a second state. When the first limiting member is in the first state, the first limiting member blocks the first baffle and the second baffle to close the opening. When the first limiting member is in the second state, the first limiting member avoids at least one of the first baffle and the second baffle to allow the first baffle or the second baffle to open the opening.

[0017] In some technical solutions, the first baffle and the second baffle may be arranged opposite each other along a first direction, or the first baffle and the second baffle may be arranged opposite each other along a second direction, wherein the first direction and the second direction are perpendicular.

[0018] In this technical solution, the first baffle and the second baffle can be arranged opposite each other along a first direction or along a second direction.

[0019] In some technical solutions, the air supply device may optionally include: a third limiting member, disposed on the body; and a fourth limiting member, disposed on the body, along the rotation axis of the fan blade assembly, with the fourth limiting member located on the side of the third limiting member away from the fan blade assembly. When the mesh assembly is connected to the body, the first baffle and the second baffle are engaged between the third limiting member and the fourth limiting member through the mounting port.

[0020] In this technical solution, the air supply device also includes a third limiting member and a fourth limiting member, both of which are installed on the machine body. The fourth limiting member is located on the side of the third limiting member away from the fan blade assembly. When the mesh cover assembly is connected to the machine body, the first baffle and the second baffle are engaged between the third limiting member and the fourth limiting member. The third limiting member and the fourth limiting member limit the second cover body, restricting the displacement of the first cover body along the rotation axis of the fan blade assembly, thereby achieving a reliable connection between the mesh cover assembly and the machine body.

[0021] In some technical solutions, optionally, the fourth limiting member includes: a first limiting part, disposed opposite to the first baffle, for limiting the first baffle; a second limiting part, disposed opposite to the second baffle, for limiting the second baffle; at least one of the first limiting part and the second limiting part is a movable member, the movable member being movably connected to the body so that the movable member can move between a first position and a second position; when the movable member is in the first position, the first baffle and the second baffle corresponding to the movable member are limited and engaged with the movable member so that the first baffle and the second baffle are joined at the opening; when the movable member is in the second position, the first baffle and the second baffle corresponding to the movable member are released from the limitation, so that at least one of the first baffle and the second baffle can rotate relative to the first cover.

[0022] In this technical solution, the fourth limiting member includes a first limiting part and a second limiting part. The first limiting part is disposed opposite to the first baffle and is used to limit the first baffle. The second limiting part is disposed opposite to the second baffle and is used to limit the second baffle. At least one of the first and second limiting parts is a movable member, which can move relative to the machine body between a first position and a second position. When the movable member is in the first position, it limits the corresponding first or second baffle, fixing the first or second baffle to the machine body in cooperation with the third limiting member. When the movable member is in the second position, it no longer limits the corresponding first or second baffle, allowing the first or second baffle to rotate and open, thus enabling the disassembly of the mesh assembly. By setting the movable parts, the rotation of the first or second baffle can be avoided when the opening needs to be opened, ensuring the reliability of the opening when the first or second baffle rotates. It can also limit the first or second baffle when the opening needs to be closed, so that the first or second baffle can cooperate with the body limit after rotation, realizing the installation of the mesh cover assembly.

[0023] In some technical solutions, optionally, one of the first baffle and the second baffle corresponding to the movable part is provided with a stop block, which can prevent the movable part from rotating.

[0024] In this technical solution, in the first baffle and the second baffle, the one opposite to the movable part is provided with a stop block, so that the stop block can cooperate with the movable part to achieve the limiting cooperation between the stop block and the movable part when the movable part is in the first position.

[0025] In some technical solutions, the movable component optionally includes a knob, which is rotatably connected to the machine body.

[0026] In this technical solution, the movable component includes a knob that can rotate between a first position and a second position to limit and release at least one of the first baffle and the second baffle, which facilitates operation and makes the assembly and disassembly of the mesh cover assembly more convenient, thus realizing quick disassembly of the mesh cover assembly.

[0027] Optionally, in some technical solutions, the first baffle is provided with a handle that protrudes from the surface of the first baffle.

[0028] In this technical solution, a handle is provided on the first baffle, which allows the user to open and close the first baffle by pulling the handle, making it easy to operate.

[0029] In some technical solutions, the handle may optionally be concealed on top of the movable part.

[0030] In this technical solution, the handle can cover the top of the moving part, thereby achieving dust and water protection for the moving part and preventing dust from entering the gap between the moving part and the body, which would affect the movement of the moving part.

[0031] In some technical solutions, the air supply device may optionally include: an electrical connection part disposed on the body; a switch part disposed on the body and connected to the electrical connection part, the switch part being disposed opposite to the movable part; when the movable part is in the first position, the switch part is triggered, and the electrical connection part is electrically connected to the drive part; when the movable part is in the second position, the switch part is in the open state, the electrical connection part is disconnected from the drive part, and the switch part is connected to the neutral wire and the live wire.

[0032] In this technical solution, the air supply device also includes an electrical connection part and a switch. The electrical connection part and the switch are located on the body. When the movable part moves between a first position and a second position, different triggering actions of the switch can be achieved, thereby realizing the electrical connection or disconnection between the electrical connection part and the drive component. Specifically, when the movable part is in the first position, the mesh assembly is connected to the body, and the movable part triggers the switch, making the electrical connection part electrically connected to the drive component, thus providing power to the drive component and driving the fan blade assembly. When the movable part is in the second position, the mesh assembly can be detached from the body. At the same time, the movable part touches the switch, making the switch open, thus disconnecting the electrical connection part from the drive component, thereby de-energizing the drive component and the fan blade assembly, making the disassembly of the mesh assembly safer.

[0033] In some technical solutions, the air supply device may optionally include a connector, wherein the first baffle and the second baffle are connected by the connector.

[0034] In this technical solution, the first baffle and the second baffle can be further connected using a connector when the opening is closed, thereby improving the connection strength between the two.

[0035] In some technical solutions, optionally, the first cover includes: a first mesh cover, the first mesh cover being annular; and a second mesh cover, along the rotation axis of the fan blade assembly, the second mesh cover being disposed on one side of the first mesh cover, and the second cover being disposed on the other side of the first mesh cover.

[0036] In this technical solution, the first cover includes a first mesh cover and a second mesh cover. The first mesh cover is ring-shaped, and the second mesh cover and the second cover are located on both sides of the first mesh cover. The second mesh cover provides protection on one side of the first mesh cover, and the second cover provides protection on the other side of the first mesh cover, and connects the mesh cover assembly to the machine body.

[0037] In some technical solutions, the first mesh cover and the second mesh cover may optionally be an integral structure or a separate structure.

[0038] In this technical solution, the first and second mesh covers are an integrated structure, which facilitates processing, reduces assembly steps, improves assembly efficiency, and lowers processing costs. Of course, the first and second mesh covers can also be separate structures for easier manufacturing.

[0039] In some technical solutions, the second cover and / or the first mesh cover may optionally be provided with air inlets.

[0040] In this technical solution, the second cover and / or the first mesh cover are provided with air inlets, which increases the flexibility of the air inlet position. At the same time, when both the second cover and the first mesh cover are provided with air inlets, the air volume can be increased and the air delivery effect can be improved.

[0041] In some technical solutions, the air supply device may optionally include a filter element located at the air inlet.

[0042] In this technical solution, the air supply device also includes a filter element, which is set at the air inlet to purify the airflow entering the mesh assembly. On the one hand, it can purify the airflow delivered by the fan assembly, improve the space quality, and avoid secondary pollution. On the other hand, it can also prevent dust from accumulating inside the mesh assembly and make it easier to clean the mesh assembly.

[0043] In some technical solutions, the filter element may optionally include: a first filter element surrounding the inner wall surface of the first mesh cover; and / or a second filter element disposed on the inner side of the second cover.

[0044] In this technical solution, the filter element includes a first filter element and / or a second filter element. The first filter element is disposed on the inner wall surface of the first mesh cover and surrounds the inner wall surface of the first mesh cover, so that the first filter element covers the air inlet on the first mesh cover, thereby improving the purification effect on the airflow. The second filter element is disposed on the inner side of the second cover body to purify the airflow entering through the air inlet on the second cover body.

[0045] In some technical solutions, the first filter element and the first mesh cover are optionally integrated into one structure, and / or the second filter element and the second cover body are optionally integrated into one structure.

[0046] In this technical solution, the first filter element can be integrated with the first mesh cover, which improves the connection strength between the first filter element and the first mesh cover. Correspondingly, the second filter element can also be integrated with the second cover, which improves the connection strength between the second filter element and the second mesh cover.

[0047] In some technical solutions, optionally, the body includes: a first housing, a portion of the drive component is disposed within the first housing; a second housing, along the rotation axis of the fan blade assembly, the second housing is disposed at one end of the first housing, the drive component includes a drive shaft, the drive shaft extends from the second housing to the outside of the first housing and is connected to the fan blade assembly, and the mesh assembly is detachably connected to the second housing.

[0048] In this technical solution, the body includes a first housing and a second housing. The second housing is located at one end of the first housing to block the first housing. The drive shaft of the drive component extends from the second housing to the outside of the first housing to connect with the fan blade assembly. The mesh assembly is detachably connected to the second housing to facilitate the disassembly and cleaning of the mesh assembly.

Detailed Implementation

[0076] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0077] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0078] The following reference Figures 1 to 23 A ventilation device is described according to some embodiments of the present invention.

[0079] like Figure 1 , Figure 2 , Figure 4 and Figure 9 As shown, according to one embodiment of the present invention, the present invention provides an air supply device 100, including: a body 1, a fan blade assembly 3 and a mesh cover assembly 4.

[0080] Specifically, the body 1 is equipped with a drive component 2; the fan blade assembly 3 is connected to the drive component 2, and the drive component 2 is used to drive the fan blade assembly 3 to rotate; the mesh cover assembly 4 is detachably connected to the body 1, and the mesh cover assembly 4 includes a first cover 40 and a second cover 41. The first cover 40 has an opening 400 on one side, through which the fan blade assembly 3 can extend into or out of the first cover 40. The second cover 41 is located at the opening 400, and at least a part of the second cover 41 is movably connected to the first cover 40 to open or close the opening 400. When the second cover 41 closes the opening 400, the mesh cover assembly 4 is connected to the body 1 through the second cover 41, and the fan blade assembly 3 is located inside the mesh cover assembly 4. When the second cover 41 opens the opening 400, the second cover 41 can be separated from the body 1.

[0081] The air supply device 100 provided by the present invention includes a body 1, a fan blade assembly 3, and a mesh cover assembly 4. A drive component 2 is disposed within the body 1, and the fan blade assembly 3 is connected to the drive component 2. The drive component 2 can drive the fan blade assembly 3 to rotate, thereby realizing the air supply function of the air supply device 100. The mesh cover assembly 4 includes a first cover 40 and a second cover 41. The second cover 41 is disposed at the opening 400 of the first cover 40, and at least a portion of the second cover 41 is movable relative to the first cover 40, allowing the second cover 41 to open or close the opening 400. When the second cover 41 closes the opening 400, the mesh cover assembly 4 is connected to the body 1 via the second cover 41, thus realizing the installation of the mesh cover assembly 4. In this case, the fan blade assembly 3 is located inside the mesh cover assembly 4, and the mesh cover assembly 4 provides protection for the fan blade assembly 3. With the second cover 41 opening 400, the second cover 41 separates from the body 1, thereby allowing the entire cover assembly to separate from the body 1, realizing the disassembly of the mesh assembly 4 from the body 1. At the same time, with the opening 400 open, the fan blade assembly 3 can be moved out of the first cover 40 through the opening 400. Thus, the user can disassemble the mesh assembly 4 without disassembling the fan blade assembly 3, which is convenient, quick, and easy to clean. In addition, after the mesh assembly 4 is disassembled, it is convenient to disassemble and clean the fan blade assembly 3.

[0082] It is understandable that when the second cover 41 has its opening 400 closed, the second cover 41 is connected to the body 1, thus achieving the connection between the entire mesh assembly 4 and the body 1; when the second cover 41 has its opening 400 open, the second cover 41 is separated from the body 1, thereby achieving the separation of the entire mesh assembly 4 from the body 1. That is, by opening and closing the second cover 41, the connection and separation of the mesh assembly 4 and the body 1 can be achieved.

[0083] In practical applications, the second cover 41 can be a single unit or comprise at least two parts. For example, when the second cover 41 is a single unit, the second cover 41 moves relative to the first cover 40 to open and close the opening 400, making the second cover 41 a single opening and closing component. When the second cover 41 comprises at least two parts, at least one part can be movably connected to the first cover 40 to open and close the opening 400. For example, at least one part can be an opening and closing component, or at least two parts can be opening and closing components. It is understood that the opening and closing components can open and close relative to the first cover 40 to open and close the opening 400.

[0084] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 13 and Figure 14 As shown, in some embodiments, optionally, the second cover 41 includes: a first baffle 42 disposed at the opening 400 and connected to the first cover 40; and a second baffle 43 disposed at the opening 400, connected to the first cover 40 and disposed opposite to the first baffle 42, wherein at least one of the first baffle 42 and the second baffle 43 is closably connected to the first cover 40 to open or close the opening 400; when the first baffle 42 and the second baffle 43 close the opening 400, the first baffle 42 and the second baffle 43 enclose an installation port 44, and the mesh assembly 4 is installed on the body 1 through the installation port 44.

[0085] In this embodiment, the second cover 41 includes a first baffle 42 and a second baffle 43. Both the first baffle 42 and the second baffle 43 are connected to the first cover 40, and at least one of the first baffle 42 and the second baffle 43 is closably connected to the first cover 40, allowing at least one of the first baffle 42 and the second baffle 43 to open or close the opening 400. When the first baffle 42 and the second baffle 43 close the opening 400, the first baffle 42 and the second baffle 43 fit together at the opening 400, thereby forming an installation port 44, allowing the second cover 41 to be fitted onto the outside of the body 1 through the installation port 44, thus enabling the installation of the mesh assembly 4. When at least one of the first baffle 42 and the second baffle 43 opens the opening 400, the first baffle 42 and the second baffle 43 separate, allowing the fan blade assembly 3 to be removed from the first cover 40 through the opening 400, thereby enabling the overall disassembly of the mesh assembly 4.

[0086] The air supply device 100 proposed in this application opens the opening 400 by the action of at least one of the first baffle 42 and the second baffle 43, thereby enabling the overall disassembly of the mesh cover assembly 4. This simplifies the disassembly and assembly process, improves assembly efficiency, and also reduces the number of parts, preventing the loss of parts during cleaning or drying.

[0087] In practical applications, the first baffle 42 and the second baffle 43 are both movably connected to the first cover 40, so that the first baffle 42 and the second baffle 43 can move relative to the first cover 40 to open the opening 400 together and increase the opening area of ​​the opening 400.

[0088] Optionally, both the first baffle 42 and the second baffle 43 are mesh structures or grid structures.

[0089] like Figure 14 As shown, in some embodiments, optionally, at least one of the first baffle 42 and the second baffle 43 is rotatably connected to the first cover 40 so that at least one of the first baffle 42 and the second baffle 43 can be flipped outward of the first cover 40 to open the opening 400.

[0090] In this embodiment, at least one of the first baffle 42 and the second baffle 43 is rotatably connected to the first cover 40, so that at least one of the first baffle 42 and the second baffle 43 can be flipped outward to open the opening 400. At the same time, the first baffle 42 and the second baffle 43 are disengaged, so that the first baffle 42 and the second baffle 43 cannot enclose the mounting port 44 used for limiting, and thus the mesh assembly 4 can be separated from the body 1 through the opening 400. When at least one of the first baffle 42 and the second baffle 43 is rotated to the position of closing the opening 400, the first baffle 42 and the second baffle 43 are joined at the opening 400, and thus the first baffle 42 and the second baffle 43 enclose the mounting port 44, realizing the connection between the mesh assembly 4 and the body 1.

[0091] Specifically, the first baffle 42 and the second baffle 43 along Figure 14 Open the opening 400 degrees in the direction indicated by the middle arrow.

[0092] like Figure 15 As shown, in some embodiments, optionally, at least one of the first baffle 42 and the second baffle 43 is provided with a first limiting member 45, and the first baffle 42 and the second baffle 43 are fixed to the first cover 40 by the first limiting member 45.

[0093] In this embodiment, at least one of the first baffle 42 and the second baffle 43 is provided with a first limiting member 45, so that the first baffle 42 and the second baffle 43 can be connected to the first cover 40, and the first baffle 42 and the second baffle 43 are kept in the closed opening 400 state.

[0094] In some embodiments, optionally, the first cover 40 is provided with a second limiting member 46, and the first limiting member 45 can be limited and engaged with the second limiting member 46; or the first limiting member 45 is rotatably provided on the side of the first baffle 42 or the second baffle 43 away from the first cover 40, for locking the first baffle 42 and the second baffle 43 when the opening 400 is closed by the first baffle 42 and the second baffle 43.

[0095] In this embodiment, a second limiting member 46 is provided on the first cover 40. Through the limiting cooperation between the first limiting member 45 and the second limiting member 46, the connection between the first baffle 42 and the second baffle 43 that are movably connected to the first cover 40 is realized, ensuring the reliability of the first baffle 42 and the second baffle 43 in closing the opening 400, preventing the first baffle 42 and the second baffle 43 that are movably connected to the first cover 40 from detaching from the first cover 40, and ensuring the reliability of the connection between the first baffle 42 and the second baffle 43 that are movably connected to the first cover 40 and the first cover 40. Alternatively, the first limiting member 45 is rotatably disposed on the first baffle 42 or the second baffle 43, and the first limiting member 45 is located on the side away from the first cover 40. When the first baffle 42 and the second baffle 43 close the opening 400, the first limiting member 45 locks the first baffle 42 and the second baffle 43 to prevent the first baffle 42 and the second baffle 43 from opening the opening 400.

[0096] Optionally, the first limiting member 45 is rotatable between a first state and a second state. When the first limiting member 45 is in the first state, the first limiting member 45 blocks the first baffle 42 and the second baffle 43 to close the opening 400. When the first limiting member 45 is in the second state, the first limiting member 45 avoids at least one of the first baffle 42 and the second baffle 43 to allow the first baffle 42 or the second baffle 43 to open the opening 400.

[0097] Optionally, a second limiting member 46 is provided on the first cover 40. When the first limiting member 45 can cooperate with the second limiting member 46 for limiting, one of the first limiting member 45 and the second limiting member 46 is a slot and the other is a buckle.

[0098] Optionally, if the first limiting member 45 is rotatably disposed on the side of the first baffle 42 or the second baffle 43 away from the first cover 40, the first limiting member 45 includes a stop bar or a locking structure.

[0099] In some embodiments, the first baffle 42 and the second baffle 43 are optionally disposed opposite each other along a first direction, or the first baffle 42 and the second baffle 43 are disposed opposite each other along a second direction, wherein the first direction is perpendicular to the second direction.

[0100] In this embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the first baffle 42 and the second baffle 43 can be arranged opposite to each other along the first direction, such as... Figure 11 and Figure 12 As shown, the first baffle 42 and the second baffle 43 can also be arranged opposite each other along the second direction.

[0101] Optionally, the first direction is perpendicular to the second direction.

[0102] Specifically, the first direction is the vertical direction, and the second direction is the horizontal direction.

[0103] Optionally, when the first baffle 42 and the second baffle 43 are arranged opposite each other along the second direction, along Figure 12 Open the opening 400 degrees in the direction indicated by the middle arrow.

[0104] like Figure 4 , Figure 5 and Figure 10 As shown, in some embodiments, optionally, the air supply device 100 further includes: a third limiting member 5, disposed on the body 1; and a fourth limiting member 6, disposed on the body 1, along the rotation axis direction of the fan blade assembly 3. The fourth limiting member 6 is located on the side of the third limiting member 5 away from the fan blade assembly 3. When the mesh cover assembly 4 is connected to the body 1, the first baffle 42 and the second baffle 43 are engaged between the third limiting member 5 and the fourth limiting member 6 through the mounting port 44.

[0105] In this embodiment, the air supply device 100 further includes a third limiting member 5 and a fourth limiting member 6. Both the third limiting member 5 and the fourth limiting member 6 are disposed on the body 1. The fourth limiting member 6 is located on the side of the third limiting member 5 away from the fan blade assembly 3. When the mesh cover assembly 4 is connected to the body 1, the first baffle 42 and the second baffle 43 are engaged between the third limiting member 5 and the fourth limiting member 6. The third limiting member 5 and the fourth limiting member 6 limit the second cover 41, restricting the displacement of the first cover 40 along the rotation axis of the fan blade assembly 3, thereby achieving a reliable connection between the mesh cover assembly 4 and the body 1.

[0106] like Figure 10As shown, in some embodiments, optionally, the fourth limiting member 6 includes: a first limiting part 60, disposed opposite to the first baffle 42, for limiting the first baffle 42; a second limiting part 61, disposed opposite to the second baffle 43, for limiting the second baffle 43; at least one of the first limiting part 60 and the second limiting part 61 is a movable member 62, which is movably connected to the body 1 so that the movable member 62 can move between a first position and a second position; when the movable member 62 is in the first position, the first baffle 42 and the second baffle 43 corresponding to the movable member 62 are limited to the movable member 62 so that the first baffle 42 and the second baffle 43 are joined at the opening 400; when the movable member 62 is in the second position, the first baffle 42 and the second baffle 43 corresponding to the movable member 62 are released from the limitation, so that at least one of the first baffle 42 and the second baffle 43 can rotate relative to the first cover 40.

[0107] In this embodiment, the fourth limiting member 6 includes a first limiting part 60 and a second limiting part 61. The first limiting part 60 is disposed opposite to the first baffle 42 and is used to limit the first baffle 42. The second limiting part 61 is disposed opposite to the second baffle 43 and is used to limit the second baffle 43. At least one of the first limiting part 60 and the second limiting part 61 is a movable member 62, which is capable of moving relative to the body 1 between a first position and a second position. Figure 3 As shown, when the movable part 62 is in the first position, the movable part 62 limits the corresponding first baffle 42 or second baffle 43, so that the first baffle 42 or second baffle 43 is fixed to the body 1 with the cooperation of the movable part 62 and the third limiting part 5. Figure 4 As shown, when the movable part 62 is in the second position, it no longer limits the corresponding first baffle 42 or second baffle 43, allowing the first baffle 42 or second baffle 43 to rotate and open the opening 400, thus enabling the disassembly of the mesh assembly 4. The movable part 62, by its design, can prevent the rotation of the first baffle 42 or second baffle 43 when the opening 400 needs to be opened, ensuring the reliability of the first baffle 42 or second baffle 43 in opening the opening 400. It can also limit the first baffle 42 or second baffle 43 when the opening 400 needs to be closed, allowing the first baffle 42 or second baffle 43 to engage with the body 1 after rotation, thus enabling the installation of the mesh assembly 4.

[0108] In practical applications, both the first baffle 42 and the second baffle 43 are rotatably connected to the first cover 40. The first limiting part 60 is a movable part 62. When the movable part 62 is in the first position, the first baffle 42 can be locked between the movable part 62 and the third limiting part 5, realizing the connection between the first baffle 42 and the body 1, thereby allowing the first baffle 42 and the second baffle 43 to be assembled at the opening 400. When the movable part 62 is in the second position, the movable part 62 no longer limits the first baffle 42, thereby allowing the first baffle 42 to move relative to the first cover 40, opening the opening 400 and enabling the disassembly of the mesh assembly 4.

[0109] When installing mesh assembly 4, such as Figure 4 As shown, first adjust the movable part 62 to the second position, then open the first baffle 42 and the second baffle 43, so that the mesh cover assembly 4 is fitted onto the outside of the fan blade assembly 3 (as shown). Figure 5 (as shown), then close the second baffle 43 (as shown). Figure 6 and Figure 8 As shown), the second baffle 43 is then positioned between the second limiting part 61 and the third limiting member 5 (as shown). Figure 7 (As shown), then close the first baffle 42 and rotate the movable part 62 to the first position (as shown). Figure 3 As shown), the first baffle 42 is limited, thereby allowing the mesh assembly 4 to be installed on the body 1.

[0110] Optionally, the second limiting part 61 includes a limiting block.

[0111] like Figure 5 As shown, in some embodiments, optionally, one of the first baffle 42 and the second baffle 43 corresponding to the movable member 62 is provided with a stop 47, which can prevent the movable member 62 from rotating.

[0112] In this embodiment, the first baffle 42 and the second baffle 43 are provided with a stop block 47 opposite to the movable member 62. The stop block 47 can cooperate with the movable member 62 to achieve a limiting cooperation between the stop block 47 and the movable member 62 when the movable member 62 is in the first position.

[0113] In some embodiments, the movable element 62 may optionally include a knob 63, which is rotatably connected to the body.

[0114] In this embodiment, the movable component 62 includes a knob 63, which can rotate between a first position and a second position to limit and release at least one of the first baffle 42 and the second baffle 43, making operation easier and making the assembly and disassembly of the mesh cover assembly 4 more convenient, thus realizing quick disassembly of the mesh cover assembly 4.

[0115] like Figure 2As shown, in some embodiments, optionally, the first baffle 42 is provided with a handle portion 48, which protrudes from the surface of the first baffle 42.

[0116] In this embodiment, the first baffle 42 is provided with a handle 48, which allows the user to open and close the first baffle 42 by pulling the handle 48, making it easy to operate.

[0117] In some embodiments, the handle 48 may optionally cover the top of the movable member 62.

[0118] In this embodiment, the handle 48 can cover the top of the movable part 62, thereby enabling the movable part 62 to be dustproof and waterproof, and preventing dust from entering the gap between the movable part 62 and the body 1, which would affect the movement of the movable part 62.

[0119] Optionally, the handle 48 includes a curved plate.

[0120] Understandably, with the first baffle 42 closing the opening 400, the handle 48 is obscured on top of the movable part 62.

[0121] like Figure 23 As shown, in some embodiments, optionally, the air supply device 100 further includes: an electrical connection part 7, disposed on the body 1; a switch 8, disposed on the body 1 and connected to the electrical connection part 7, the switch 8 being disposed opposite to the movable part 62, the switch 8 being triggered when the movable part 62 is in the first position, and the electrical connection part 7 being electrically connected to the drive part 2; when the movable part 62 is in the second position, the switch 8 is in the open state, the electrical connection part 7 is disconnected from the drive part 2, and the switch 8 is connected to the neutral wire and the live wire.

[0122] In this embodiment, the air supply device 100 further includes an electrical connection part 7 and a switch 8. The electrical connection part 7 and the switch 8 are disposed on the body 1. When the movable part 62 moves between a first position and a second position, it can realize different triggering actions of the switch 8, thereby realizing the electrical connection or disconnection between the electrical connection part 7 and the drive part 2. Specifically, when the movable part 62 is in the first position, the mesh assembly 4 is connected to the body 1, and the movable part 62 triggers the switch 8, making the electrical connection part 7 electrically connected to the drive part 2, thus providing power to the drive part 2 and driving the fan blade assembly 3. When the movable part 62 is in the second position, the mesh assembly 4 can be detached from the body 1. At the same time, the movable part 62 touches the switch 8, making the switch 8 in an open state, thus disconnecting the electrical connection part 7 from the drive part 2, thereby de-energizing the drive part 2 and the fan blade assembly 3, making the removal of the mesh assembly 4 safer.

[0123] In practical applications, the switch element 8 can be two microswitches, one for the neutral wire and one for the live wire. When the movable element 62 is in the first position, both microswitches are triggered, energizing the circuit. When the movable element 62 is in the second position, both microswitches are in the open state. The switch element 8 can also be a rocker switch, enabling simultaneous opening and closing of the neutral and live wires.

[0124] Optionally, the switch 8 is rotatably or slidably connected to the body 1, so that the switch 8 can rotate between the first position and the second position, or slide between the first position and the second position, thereby triggering the first end of the switch 8 at the first position and triggering the second end of the switch 8 at the second position.

[0125] In some embodiments, the air supply device 100 may optionally include a connector, wherein the first baffle 42 and the second baffle 43 are connected by the connector.

[0126] In this embodiment, the first baffle 42 and the second baffle 43 can be further connected using a connector when the opening 400 is closed, thereby improving the connection strength between the two.

[0127] like Figure 15 As shown, in some embodiments, optionally, the first cover 40 includes: a first mesh cover 401, which is annular; and a second mesh cover 402, which is disposed on one side of the first mesh cover 401 along the rotation axis of the fan blade assembly 3, and the second cover 41 is disposed on the other side of the first mesh cover 401.

[0128] In this embodiment, the first cover 40 includes a first mesh cover 401 and a second mesh cover 402. The first mesh cover 401 is annular, and the second mesh cover 402 and the second cover 41 are located on both sides of the first mesh cover 401. The second mesh cover 402 provides protection on one side of the first mesh cover 401, and the second cover 41 provides protection on the other side of the first mesh cover 401, and connects the mesh cover assembly 4 to the body 1.

[0129] In some embodiments, the first mesh cover 401 and the second mesh cover 402 may be an integral structure or a separate structure.

[0130] In this embodiment, when the first mesh cover 401 and the second mesh cover 402 are an integral structure, it is easier to process, reduces assembly steps, improves assembly efficiency, and reduces processing costs. When the first mesh cover 401 and the second mesh cover 402 are separate structures, it is possible to manufacture the first mesh cover 401 and the second mesh cover 402 separately, which facilitates maintenance, replacement, transportation, and storage.

[0131] like Figure 16As shown, in some embodiments, the second cover 41 and / or the first mesh cover 401 are optionally provided with air inlets 49.

[0132] In this embodiment, the second cover 41 and / or the first mesh cover 401 are provided with air inlets 49, which increases the flexibility of the air inlet position. When both the second cover 41 and the first mesh cover 401 are provided with air inlets 49, the air intake volume can be increased, and the air delivery effect can be improved.

[0133] In practical applications, the second cover 41 has a grid structure, which forms an air inlet 49 in the gap between the grids.

[0134] like Figure 18 and Figure 19 As shown, in some embodiments, the air supply device 100 may optionally include a filter element 9 disposed at the air inlet 49.

[0135] In this embodiment, the air supply device 100 also includes a filter element 9, which is disposed at the air inlet 49, thereby purifying the airflow entering the mesh assembly 4. On the one hand, it can purify the airflow delivered by the fan blade assembly 3, improve the space quality, and avoid secondary pollution. On the other hand, it can also prevent dust from accumulating inside the mesh assembly 4, making it easier to clean the mesh assembly 4.

[0136] like Figure 18 As shown, in some embodiments, the filter element 9 may optionally include: a first filter element 90 surrounding the inner wall surface of the first mesh cover 401; and / or a second filter element 91 disposed on the inner side of the second cover 41.

[0137] In this embodiment, the filter element 9 includes a first filter element 90 and / or a second filter element 91. The first filter element 90 is disposed on the inner wall surface of the first mesh cover 401 and surrounds the inner wall surface of the first mesh cover 401, so that the first filter element 90 covers the air inlet 49 on the first mesh cover 401, thereby improving the purification effect on the airflow. The second filter element 91 is disposed on the inner side of the second cover 41 to purify the airflow entering through the air inlet 49 on the second cover 41.

[0138] Optionally, the first filter element 90 and the second filter element 91 may include a common nylon filter or a high-efficiency particulate air (HEPA) filter, or other types of filters.

[0139] In some embodiments, the first filter element 90 and the first mesh cover 401 are optionally integrated, and / or the second filter element 91 and the second cover 41 are optionally integrated.

[0140] In this embodiment, the first filter element 90 can be integrated with the first mesh cover 401, which improves the connection strength between the first filter element 90 and the first mesh cover 401. Correspondingly, the second filter element 91 can also be integrated with the second cover 41, which improves the connection strength between the second filter element 91 and the second mesh cover 402.

[0141] Optionally, the first filter element 90 is integrally injection molded with the first mesh cover 401, and the second filter element 91 is integrally injection molded with the second cover body 41.

[0142] like Figure 9 As shown, in some embodiments, optionally, the body 1 includes: a first housing 10, a portion of the drive member 2 is disposed within the first housing 10; a second housing 12, along the rotation axis of the fan blade assembly 3, the second housing 12 is disposed at one end of the first housing 10, the drive member 2 includes a drive shaft 20, the drive shaft 20 extends from the second housing 12 to the outside of the first housing 10 and is connected to the fan blade assembly 3, and the mesh cover assembly 4 is detachably connected to the second housing 12.

[0143] In this embodiment, the body 1 includes a first housing 10 and a second housing 12. The second housing 12 is disposed at one end of the first housing 10 to block the first housing 10. The drive shaft 20 of the drive component 2 extends from the second housing 12 to the outside of the first housing 10 to connect with the fan blade assembly 3. The mesh cover assembly 4 is detachably connected to the second housing 12 to facilitate the disassembly and cleaning of the mesh cover assembly 4.

[0144] Optionally, the second cover 41 is detachably connected to the second housing 12.

[0145] Optionally, the air supply device 100 includes a fan.

[0146] like Figure 16 , Figure 17 , Figure 20 , Figure 21 and Figure 22 As shown, optionally, the air supply device 100 further includes: a support rod, with the body 1 located on top of the support rod; when the first baffle 42 and the second baffle 43 are arranged opposite each other in the vertical direction, the second baffle 43 is provided with a clearance opening 440, which communicates with the mounting opening 44 and is arranged opposite to the support rod, and the clearance opening 440 is used to avoid the support rod during the rotation of the second baffle 43.

[0147] In this embodiment, the air supply device 100 also includes a support rod, with the main body disposed on the top of the support rod so that the fan blade assembly 3 is in a higher position. When the first baffle 42 and the second baffle 43 are arranged vertically opposite each other, the second baffle 43 is provided with a clearance opening 440. This allows the second baffle 43 to avoid the support rod during rotation, ensuring the reliability of the second baffle 43's opening.

[0148] In some embodiments, optionally, the body 1 is provided with a stop portion, which is disposed opposite to the clearance opening 440 and is used to block the clearance opening 440.

[0149] In this embodiment, the stop is used to block the clearance opening 440 on the mesh assembly 4 to prevent the user's hand from reaching into the mesh assembly 4 through the clearance opening 440 and causing injury.

[0150] In specific applications, this application protects a mesh assembly 4, such as the assembly method of the front first cover (first mesh 401), the middle first cover (e.g., second mesh 402), and the rear first cover (e.g., second cover 41) with the body 1.

[0151] The mesh cover assembly 4 can be composed of a front first cover, a middle first cover, and a first baffle 42 and a second baffle 43 of a rear first cover. Alternatively, the second cover 41 can be changed from a top-bottom arrangement to a left-right arrangement. The second cover 41 can also be designed as a single, inseparable unit. Optionally, the front and middle first covers can be combined into a single component, which reduces the number of molds and parts, resulting in a more integrated appearance.

[0152] Objective: To facilitate quick disassembly and cleaning for users, and to comply with safety regulations, it may be necessary to design the location of fixing screws (e.g., screw connection at the junction of the first baffle 42 and the second baffle 43). To further facilitate quick disassembly and cleaning, another solution is designed: the mesh cover assembly 4 does not require screws. That is, when the user rotates the knob 63, the entire unit is completely disconnected (i.e., the live wire and the neutral wire). (There are several ways to disconnect the entire pole, such as adding two microswitches or directly connecting a rocker switch to achieve simultaneous disconnection and closure of the live and neutral wires). An example of the implementation method is as follows: When it is necessary to disassemble and clean the mesh cover assembly 4 and the fan blade assembly 3, simply turn the knob 63. At this time, the fan is completely disconnected (neutral wire and live wire), which ensures safety and avoids mechanical damage.

[0153] The assembly method of the first baffle 42 and the second baffle 43 of the rear first cover with the middle first cover is: rotational connection plus snap-locking limit.

[0154] The mesh cover assembly 4 itself is not electrified. After it is removed, it can be soaked and rinsed at will without worrying about affecting the performance of the whole machine. The main body 1 is electrified. After the non-electrified part (mesh cover assembly 4) is removed, the biggest remaining problem is to disassemble the fan blade assembly 3. Since the mesh cover assembly 4 has been removed, disassembling and cleaning the fan blade assembly 3 becomes very easy. Therefore, this embodiment has the advantages of simple operation, low cost and high modularity.

[0155] Optionally, this application also protects a quick-release filter (e.g., filter element 9) purification solution, wherein the filter can be a regular nylon mesh or a professional-grade HEPA filter, etc.

[0156] The purification positions are mainly arranged around the air inlet 49, and are divided into axial and circumferential directions. The filters for each direction can be either a separate filter or an integral part of the corresponding grille (e.g., the first shroud in the middle) through injection molding.

[0157] The air supply device 100 proposed in this application allows users to disassemble and clean the filter and mesh cover assembly 4 without disassembling the fan blade assembly 3. This is convenient, quick, and cost-effective. Moreover, after adding a filter at the air inlet 49, the cycle in which the fan blade assembly 3 gets dirty will be extended. Sometimes, it is not necessary to clean the fan blade assembly 3 at all, which reduces the difficulty and frequency of cleaning the fan for users.

The terms "installed," "connected," "linked," and "fixed," etc., should be interpreted broadly.
