[0052] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0053] Figure 1-Figure 3 FIG. 1 shows a structural diagram of an aeration device 100 according to an embodiment of the present application. Figure 1-Figure 3 As shown, the aeration device 100 may include:

[0054] Intake pipe 110;

[0055] an aeration plate 120 , wherein the aeration plate 120 is disposed on the air inlet pipe 110 ;

[0056] The connecting assembly 130 is disposed in the air inlet pipe 110 and passes through the air inlet pipe 110 to connect with the aeration plate 120;

[0057] an aeration membrane 140 , wherein the aeration membrane 140 is disposed on the aeration plate 120 ;

[0058] The mounting assembly 150 is disposed on the aeration plate 120 to fix the aeration membrane 140 on the aeration plate 120 . Gas is transported from the air inlet pipe 110 to the aeration plate 120 via the connecting assembly 130 and outputted through the aeration membrane 140 .

[0059] In this embodiment, during installation, after the connecting assembly 130 is passed through the air inlet pipe 110, the aeration plate 120 is installed on the air inlet pipe 110. After installation, the aeration membrane 140 is sleeved on the air inlet plate. After sleeved, the mounting assembly 150 is set on the aeration plate 120 so that the side of the mounting assembly 150 is in contact with the aeration membrane 140, and then the aeration membrane 140 is fixed to the aeration plate 120. After installation, gas is introduced into the air inlet pipe 110, and the gas is transported to the aeration plate 120 through the connecting assembly 130, and then transported to the aeration membrane 140 through the aeration plate 120 for aeration.

[0060] By setting up the connecting component 130, the gas is directly transported from the air inlet pipe 110 to between the aeration plate 120 and the aeration membrane 140, thereby avoiding gas leakage at the connection between the air inlet pipe 110 and the aeration plate 120, which affects the aeration effect. At the same time, by setting up the mounting component 150, the installation between the aeration membrane 140 and the aeration plate 120 is facilitated, thereby avoiding the aeration membrane 140 from falling off the aeration plate 120, which affects the use of the aeration device 100.

[0061] like Figure 1-Figure 2 As shown, in one embodiment,

[0062] The connection assembly 130 includes:

[0063] The base 131 is fitted with the air inlet pipe 110;

[0064] A connecting bolt 132 passes through the base 131 and extends to the aeration plate 120. The aeration plate 120 has a first groove 121. One end of the connecting bolt 132 away from the base 131 extends into the first groove 121. The connecting bolt 132 has a gas transmission channel therein. The connecting bolt 132 also has an air inlet hole 133. The air inlet hole 133 is connected to the gas transmission channel. The gas outlet of the gas transmission channel is located in the first groove 121.

[0065] The sealing member 134 is disposed in the first groove 121 , and one end of the connecting bolt 132 away from the base 131 is threadedly connected to the sealing member 134 .

[0066] In this embodiment, the cross-section of the connecting bolt 132 is T-shaped. The sealing member 134 is pre-placed in the first groove 121. After the connecting bolt 132 passes through the base 131, it is threadedly connected to the sealing member 134 in the first groove 121. Then, the connecting bolt 132 cooperates with the sealing member 134 to connect the aeration plate 120, the air inlet pipe 110, and the base 131.

[0067] Furthermore, the first groove 121 is in a square structure, and the shape of the sealing member 134 is adapted to the first groove 121. When the connecting bolt 132 passes through the intake pipe 110 and is placed in the first groove 121, the sealing member 134 is threadedly connected to the connecting bolt 132 by rotating the connecting bolt 132. The square shape of the sealing member 134 prevents the sealing member 134 from rotating with the connecting bolt 132.

[0068] A hole for the connecting bolt 132 to pass through is defined at the bottom of the first groove 121 .

[0069] The top of the connecting bolt 132 passes through the bottom of the first groove 121 and enters the first groove 121. The bottom of the first groove 121 is provided with a hole for the connecting bolt 132 to pass through.

[0070] It should be noted that both the base 131 and the aeration plate 120 are provided with arc-shaped grooves adapted to the air inlet pipe 110;

[0071] The arc grooves provided on the base 131 and the aeration plate 120 ensure that the base 131 and the aeration plate 120 can better fit with the air inlet pipe 110, thereby ensuring the sealing of the connection between the base 131, the aeration plate 120 and the air inlet pipe 110.

[0072] like Figure 1-Figure 2 As shown, in one embodiment,

[0073] The sealing member 134 has a plurality of through holes 135 . The gas in the air inlet pipe 110 passes through the air inlet holes 133 , is transported to the first groove 121 by the air delivery channel, and is output from the aeration plate 120 through the through holes 135 .

[0074] In this embodiment, the connecting bolt 132 has an air inlet hole 133, which is connected to the air hole. The air inlet hole 133 is located in the air inlet pipe 110, and the air outlet end is located on one end of the connecting bolt 132 located in the first groove 121. The gas is transported to the air inlet hole 133 through the air inlet pipe 110, and is transported to the first groove 121 through the connecting bolt 132, and finally output through the through hole 135 on the sealing member 134. Compared with the traditional air inlet pipe 110 directly connected to the aeration plate 120, the sealing performance is better, thereby preventing gas leakage from the connection between the aeration plate 120 and the air inlet pipe 110.

[0075] like Figure 1-Figure 2 As shown, in one embodiment,

[0076] The connection assembly 130 further includes:

[0077] The gasket 136 is detachably mounted on the sealing member 134 , and the plurality of through holes 135 are all located below the gasket 136 .

[0078] In this embodiment, the gasket 136 is provided on the sealing member 134 so as to cover the air hole, thereby improving the aeration effect of the air hole. The gasket 136 prevents the gas from flowing back, and has the same effect as a common check valve on the market.

[0079] Furthermore, the gasket 136 is arranged on the sealing member 134 through a connecting member, and the connecting member is a bolt.

[0080] like Figure 1-Figure 3 As shown, in one embodiment,

[0081] The aeration plate 120 includes:

[0082] Plate 122;

[0083] The boss 123 is provided on the plate body 122 . The opening of the first groove 121 is located on the boss 123 . The aeration membrane 140 is provided on the plate body 122 through the boss 123 .

[0084] In this embodiment, a boss 123 is provided on the plate body 122. When the aeration membrane 140 is installed, the aeration membrane 140 wraps the boss 123 inside, thereby ensuring the sealing when the aeration membrane 140 is connected to the plate body 122. The aeration membrane 140 is positioned before installing the connecting assembly 130 to avoid the aeration membrane 140 from being offset, which affects the airtightness between the aeration membrane 140 and the plate body 122. The connecting assembly 130 is detachably connected to the plate body 122, which facilitates fixing the aeration membrane 140 on the boss 123. This avoids damage to the aeration membrane 140 when directly fixing the aeration membrane 140 on the aeration plate 120, which affects the secondary use of the aeration membrane 140.

[0085] like Figure 1-Figure 3 As shown, in one embodiment,

[0086] The aeration plate 120 also includes:

[0087] The first protrusion 124 is arranged on the boss 123 in an annular manner, and the aeration membrane 140 is provided with a second groove 141 that matches the shape of the first protrusion 124 and the boss 123 .

[0088] In this embodiment, by providing the first protrusion 124 , when the aeration membrane 140 is sleeved on the boss 123 , the first protrusion 124 is located inside the aeration membrane 140 ;

[0089] Further,

[0090] The aeration membrane 140 has a second groove 141 that matches the shape of the boss 123. The first protrusion 124 ensures the stability of the connection between the aeration membrane 140 and the boss 123. While performing the preliminary positioning of the aeration membrane 140, the stability of the connection between the aeration membrane 140 and the aeration plate 120 is ensured.

[0091] like Figure 1-Figure 3 As shown, in one embodiment,

[0092] The mounting assembly 150 includes:

[0093] A pressure frame 151 is provided on the plate body 122 , and the inner area of ​​the pressure frame 151 is the same as the area of ​​the aeration membrane 140 ;

[0094] The second protrusion 152 is provided on the pressure frame 151 . The size of the second protrusion 152 is smaller than the size of the aeration membrane 140 .

[0095] In this embodiment, when the pressure frame 151 is installed on the aeration plate 120, the side of the aeration membrane 140 is in contact with the inner wall of the pressure frame 151. The second protrusion 152 is provided on the aeration membrane 140 to exert pressure on the aeration membrane 140, so that the aeration membrane 140 is in contact with the plate body 122.

[0096] Further,

[0097] The size of the aeration membrane 140 is larger than that of the second protrusion 152 and smaller than that of the pressure frame 151;

[0098] The size of the aeration membrane 140 is smaller than that of the pressure frame 151, which facilitates the pressure frame 151 to be mounted on the aeration membrane 140. When the pressure frame 151 is installed on the aeration plate 120, since the size of the aeration membrane 140 is larger than the size of the second protrusion 152, the second protrusion 152 can fix the aeration membrane 140 on the aeration plate 120, and cooperate with the first protrusion 124 to fix the aeration membrane 140 to prevent the aeration membrane 140 from falling off.

[0099] like Figure 1-Figure 3 As shown, in one embodiment,

[0100] The aeration membrane 140 has a plurality of pores.

[0101] In this embodiment,

[0102] When the aeration membrane 140 is connected to the boss 123, the gas in the air inlet pipe 110 enters the first groove 121 through the aeration holes on the boss 123 and is discharged through the plurality of air holes. The second protrusion 152 on the pressure frame 151 cooperates with the first protrusion 124 to ensure that the gas is located between the boss 123 and the aeration membrane 140 when it is discharged from the aeration holes on the boss 123 and is discharged through the air holes on the aeration membrane 140, thereby improving the aeration efficiency and reducing the occurrence of air leakage.

[0103] Furthermore, the plurality of air holes are connected to the second groove 141 .

[0104] like Figure 2 As shown, in one embodiment, it also includes:

[0105] A plurality of sealing rings 160 are respectively disposed between the base 131 and the air inlet pipe 110 , between the connecting bolts 132 and the base 131 , and between the plate 122 and the air inlet pipe 110 .

[0106] In this embodiment, sealing rings 160 are provided between the base 131 and the air intake pipe 110 , the connecting bolts 132 and the base 131 , and the plate 122 and the air intake pipe 110 , thereby ensuring the sealing of the connection between the air intake pipe 110 and the plate 122 .

[0107] Furthermore, recesses adapted to the sealing ring 160 are provided on the base 131 , the connecting bolts 132 , the air inlet pipe 110 and the plate body 122 .
