Figure 10 to Figure 18 shows the 3rd preferred embodiment of this Diskus of the application, its structure and embodiment The structure of Diskus is essentially identical in one, and the main difference of the two is the following aspects：

First, the connected mode between upper casing 9, loading plate 1, suction nozzle 3 and lower casing 8 is different.

The sidepiece of loading plate 1 is integrally formed with two loading plate lug 1h being spaced apart, the two loading plate lugs 1h Inner side close to each other mutually deviates from integrally formed with coaxially arranged cylindrical inner convex platform 1j, the two loading plate lugs 1h Outside integrally formed with coaxially arranged cylindrical outer lug boss 1k.Foregoing inner convex platform 1j and outer lug boss 1k are also coaxially arranged.

The sidepiece of suction nozzle 3 is opened up together integrally formed with two suction nozzle lug 3a being spaced apart, the two suction nozzle lugs 3a Suction nozzle turn hole 3b that is that axle is arranged and matching with the inner convex platform 1j, the two suction nozzle turn holes 3b rotate be set in convex respectively Outside platform 1j.So realize being pivotally connected for suction nozzle 3 and loading plate 1.

Integrally formed with a upper casing lug 9c, the left and right sides one of upper casing lug 9c on the bottom opening side of upper casing 9 Body formed to have coaxially arranged cylindrical left boss 9f and right boss, left boss 9f and right boss rotate be set in suction nozzle respectively In two suction nozzle turn hole 3b on 3.So realize being pivotally connected for upper casing 9 and loading plate 1.

The open topped side of lower casing 8 is integrally formed with two lower casing lug 8d being spaced apart, the two lower casing lugs 8d Coaxially arranged lower casing turn hole 8e is opened up, the totally two lower casing turn hole 8e on two lower casing lug 8d are respectively sleeved at outer lug boss 1k Outward.When needing to clean lower casing 8 and capsule chamber 4, lower casing 8 is opened in upset, very convenient.

The relative inner of two suction nozzle lug 3a forms upper casing and installs guiding groove 3d on suction nozzle 3, and suction nozzle 3 and upper casing 9 are assembled When, left boss 9f and right boss are installed guiding groove 3d and are slipped into suction nozzle turn hole 3b by the upper casing, realize suction nozzle 3 and upper casing 9 It is pivotally connected.

The open topped side of lower casing 8 is integrally formed with two lower casing lug 8d being spaced apart, the two lower casing lugs 8d Coaxially arranged lower casing turn hole 8e is opened up, the totally two lower casing turn hole 8e on two lower casing lug 8d are respectively sleeved at outer lug boss 1k Outward, being pivotally connected for lower casing 8 and loading plate 1 is so realized.When needing to clean lower casing 8 and capsule chamber 4, under upset is opened Shell 8, it is very convenient.
