[0005] In order to solve the above technical problem, the utility model provides an aeration device, which is characterized by comprising a cavity joint, a gland arranged at two ends of the cavity joint and a sintered quartz aeration disc arranged between the cavity joint and the gland, the gland is provided with a closure, and the gland limits the position of the sintered quartz aeration disc.

[0006] Further, the cavity joint is a ring structure with open two ends and a hollow inside, one mounting position is designed at each end of the cavity joint, and the sintered quartz aeration disc is placed in the mounting position.

[0007] Further, the aeration device further comprises an air inlet pipe, and the air inlet pipe is arranged on one side of the cavity joint.

[0008] Further, the closure further comprises an inner sealing gasket, and the inner sealing gasket is wrapped around the outer circle of the sintered quartz aeration disc.

[0009] Further, the aeration device further comprises a ring-shaped sealing square gasket, and the ring-shaped sealing square gasket is sleeved into the outer sealing groove of the cavity joint from the outside of the cavity joint.

[0010] Further, the gland compresses the inner sealing gasket and the ring-shaped sealing square gasket, and is connected with the cavity joint through threads.

[0011] The aeration device provided by the utility model has the following advantages:

[0012] The utility model adopts a reasonable overall structure distribution, and the filter mesh structure of the sintered quartz aeration plate can automatically buffer the size of the air intake to ensure the uniformity of the air intake and improve the aeration efficiency; the sintered quartz aeration plate is wrapped with an inner sealing gasket, so that the quartz aeration plate is tightly sealed, and a good sealing performance is maintained from the inside to the outside. The connection avoids the inclusion of particles of liquid medicine and residual materials, eliminating cleaning dead corners; the thread is tightened and disassembled conveniently, and the sealing strength can be conveniently adjusted without worrying about the leakage of the seal. The sealing is high, and the assembly accuracy requirements are easier to achieve, and the effectiveness and adaptability are stronger. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] like Figures 1 to 2 As shown, the embodiment of the present utility model proposes an aeration device, including a gland 1, a sintered quartz aeration plate 2 and a cavity joint 4;

[0021] The cavity joint 4 is open at both ends and has a hollow interior, with a mounting position designed at each of the upper and lower ends; and an air inlet port 6 is also provided on the side of the cavity joint 4 for inputting gas.

[0022] The aeration device further comprises a gland 1 arranged at both ends of the cavity joint 4, which limits the position of the sintered quartz aeration disc 2; the gland 1 is provided with a closure part, which comprises an inner sealing gasket 3 wrapped along the outer circle of the sintered quartz aeration disc 2, so that the side wall and the upper and lower outer circle of the sintered quartz aeration disc 2 are tightly wrapped by the inner sealing gasket 3, and the inner sealing gasket 3 and the sintered quartz aeration disc 2 are installed in the flat and close-together installation position as a whole, which greatly improves the sealing performance and avoids the inclusion and residue of particles of the liquid medicine material, and eliminates the cleaning dead angle.
