Among them, at least one of the mesh cover assembly 4 and the main body 1 is provided with a buffer 5. When the mesh cover assembly 4 is installed on the main body 1, the mesh cover assembly 4 contacts the main body 1 through the buffer 5. The buffer 5 separates the mesh cover assembly 4 from the main body 1, so that the path for the driving member 2 to transmit vibration to the mesh cover assembly 4 when working is blocked, thereby preventing the vibration generated by the driving member 2 from being transmitted to the mesh cover assembly 4, thereby improving the overall vibration of the air supply device when working.

[0061] Optionally, the driving member 2 includes a motor. Optionally, the motor includes an output shaft, and the output shaft is connected to the fan blade 3 to drive the fan blade 3 to rotate.

[0062] Specifically, the buffer member 5 may be disposed on the main body 1 , or on the mesh assembly 4 , or the buffer member 5 may be disposed on the main body 1 and the mesh assembly 4 respectively, so as to enhance the blocking effect against vibration.

[0063] like Figure 3 As shown, in some embodiments, optionally, a mounting opening 40 is provided on the mesh cover assembly 4, the mesh cover assembly 4 is sleeved on the outside of the main body 1 through the mounting opening 40, and the buffer member 5 is at least provided between the inner wall surface of the mounting opening 40 and the main body 1.

[0064] In this embodiment, the mesh cover assembly 4 is provided with a mounting opening 40, and the mesh cover assembly 4 is sleeved on the outer side of the main body 1 through the mounting opening 40, thereby realizing connection with the main body 1. The buffer 5 is at least provided between the inner wall surface of the mounting opening 40 and the main body 1, thereby making the mesh cover assembly 4 contact with the main body 1 through the buffer 5, thereby preventing the vibration of the driving member 2 from being transmitted to the mesh cover assembly 4 during operation, thereby improving the vibration of the air supply device as a whole.

[0065] like Fig. 9 and Fig.12 As shown, in some embodiments, optionally, the main body 1 includes: a shell 10, a driving member 2 is arranged in the shell 10; a first limiting portion 11 is arranged in the shell 10; a second limiting portion 12 is arranged in the shell 10, along the rotation axis direction of the fan blade 3, the second limiting portion 12 is located on the side of the first limiting portion 11 away from the fan blade 3, and the buffer member 5 is arranged between the first limiting portion 11 and the second limiting portion 12; when the mesh cover assembly 4 is connected to the main body 1, the part of the mesh cover assembly 4 with the installation port 40 is clamped between the first limiting portion 11 and the second limiting portion 12.

When the mesh cover assembly 4 is connected to the main body 1, the part of the mesh cover assembly 4 provided with the mounting opening 40 is clamped between the first limiting portion 11 and the second limiting portion 12. The first limiting portion 11 and the second limiting portion 12 are used to limit the mesh cover assembly 4, so that the mesh cover assembly 4 is reliably installed on the main body 1, and the mesh cover assembly 4 is prevented from moving relative to the main body 1 along the rotation axis direction of the fan blade 3. At the same time, the buffer 5 is arranged between the first limiting portion 11 and the second limiting portion 12. The first limiting portion 11 and the second limiting portion 12 realize the fixation of the buffer 5, and also ensure the relative position of the mesh cover assembly 4 and the buffer 5, and prevent the relative position of the buffer 5 and the mesh cover assembly 4 from changing, resulting in the transmission of vibration to the mesh cover assembly 4.

[0067] In some embodiments, optionally, the buffer member 5 is attached to the first limiting portion 11 and the second limiting portion 12 .

[0068] In this embodiment, when the mesh cover assembly 4 is installed on the main body 1, the mesh cover assembly 4 is in contact with the shell 10, the first limit portion 11 and the second limit portion 12. Therefore, the buffer member 5 is attached to the first limit portion 11 and the second limit portion 12, which can reduce the direct contact area between the mesh cover assembly 4 and the main body 1, thereby improving the vibration reduction effect of the buffer member 5.

[0069] It can be understood that the buffer member 5 includes a portion that fits with the housing 10 , a portion that fits with the first limiting portion 11 , and a portion that fits with the second limiting portion 12 .

[0072] Optionally, a shaft hole is provided on the second shell 104 , and the output shaft of the driving member 2 passes through the shaft hole on the second shell 104 and extends out of the first shell 102 .

[0074] In this embodiment, the buffer 5 includes an elastic member, and along the circumference of the shell 10, the buffer 5 is a closed structure, so that the buffer 5 can be firmly mounted on the shell 10 through its own elasticity, so that the buffer 5 and the shell 10 have an interference fit, thereby improving the connection strength between the buffer 5 and the shell 10, ensuring the position of the buffer 5 relative to the mesh cover assembly 4, and further ensuring the vibration reduction effect.

[0075] It is understandable that the buffer 5 is a closed structure along the circumference of the second shell 104 , for example, the buffer 5 has an annular structure, or the buffer 5 has multiple annular structures, so that the buffer 5 is connected end to end along the circumference of the second shell 104 .

[0076] Specifically, the buffer 5 includes an elastic member, so that the buffer 5 has a certain elasticity. On the one hand, the buffer 5 can be tightly wrapped around the outer side of the second shell 104 through elasticity, and on the other hand, the buffer 5 can absorb vibrations, thereby preventing the vibrations from being transmitted to the mesh cover assembly 4.

[0080] In this embodiment, the mesh cover assembly 4 is detachably connected to the housing 10, so that the mesh cover assembly 4 can be disassembled as a whole for cleaning, thereby improving the cleaning effect. At the same time, the mesh cover assembly 4 is a non-electrical component and can be rinsed and soaked at will without affecting the use of the whole machine. In addition, the mesh cover assembly 4 is modularized, which improves the assembly efficiency, is not easy to be lost during the overall disassembly and washing process, and does not take up too much space during the drying process.

In this case, the fan blade 3 is located in the mesh cover assembly 4, and the fan blade 3 is protected by the mesh cover assembly 4. When the second mesh cover 42 opens the opening 410, the second mesh cover 42 is separated from the body, so that the entire cover body assembly can be separated from the body, and the mesh cover assembly 4 and the body can be disassembled. At the same time, when the opening 410 is opened, the fan blades 3 can be moved out of the first mesh cover 41 through the opening 410, and the user can complete the disassembly of the mesh cover assembly 4 without removing the fan blades 3. This is convenient and quick, and it is easy to clean the mesh cover assembly 4. At the same time, after the mesh cover assembly 4 is removed, the fan blades 3 can be easily disassembled and cleaned.

[0083] In a specific application, the second mesh cover 42 can be a whole or include at least two parts. For example, when the second mesh cover 42 is a whole, the second mesh cover 42 moves relative to the first mesh cover 41 to open and close the opening 410, so that the second mesh cover 42 is a whole opening and closing member; when the second mesh cover 42 includes at least two parts, at least one part can be movably connected to the first mesh cover 41 to open and close the opening 410, for example, at least one part is an opening and closing member, or at least two parts are opening and closing members.

When the first baffle 43 and the second baffle 44 are assembled at the opening 410, the first baffle 43 and the second baffle 44 enclose the installation opening 40, so that the mesh cover assembly 4 can be clamped between the first limiting portion 11 and the second limiting portion 12 through the installation opening 40, thereby realizing the installation of the mesh cover assembly 4 and the housing 10. When at least one of the first baffle 43 and the second baffle 44 moves relative to the first mesh cover 41 to open the opening 410, the first baffle 43 and the second baffle 44 cannot enclose the installation port 40, thereby releasing the coordination between the mesh cover assembly 4 and the shell 10, so that the mesh cover assembly 4 can be removed from the shell 10, thereby realizing the disassembly and cleaning of the mesh cover assembly 4.

[0115] In a specific application, the present application adds a buffer pad (e.g., buffer member 5) between the mesh cover assembly 4 and the body (e.g., main body 1) components to completely separate the two, so that the transmission path of the vibration is blocked, and the contact area between the mesh cover assembly 4 and the body is reduced compared to the conventional installation method, which is conducive to blocking and weakening the transmission of vibration. The buffer pad is a closed structure, so that the elastic deformation of the buffer pad can be used to firmly fix it on the front shell of the motor (e.g., the second shell 104). Since the main function of the mesh cover assembly 4 in contact with the buffer pad is to provide protection, specifically including protection against mechanical rotation damage and protection of the motor, therefore, minimizing the contact area of ​​the remaining body components or the mesh cover assembly 4 will significantly reduce the vibration of the entire machine, that is, blocking its transmission from the transmission path of the vibration. The present application proposes a vibration isolation solution based on a quick-release method. By designing a vibration reduction device for the fan, the vibration and jitter problems of the fan during operation are solved.
