Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

FIG. 3 is a schematic structural view of the air intake device of the present invention; the air inlet device 7 comprises an air cylinder 71, one end of the air cylinder 71 is sleeved with a second sealing ring 72, the middle part of the second sealing ring 72 is sleeved with an air pressure gauge 73 extending outwards, and the middle part of the air pressure gauge 73 is provided with a communicating pipe 74. The second sealing ring 72 can ensure the sealing effect between the air cylinder 71 and the communicating pipe 74, the barometer 73 can monitor the air pressure at the communicating pipe 74 in real time, the air cylinder 71 is an important framework support for detecting the tightness of the valve 9, when the air cylinder 71 is continuously inflated, whether air leaks or not can be observed, and the tightness of the valve 9 can be detected through the change of the air pressure and whether bubbles emerge or not.

In this embodiment, the collar 8 includes a ring body 81, a rotating ring 82 is installed at the middle of the side surface of the ring body 81, a rubber layer 83 is fixedly connected to the inner side of the ring body 81, and a bolt 84 is sleeved on one end of the ring body 81 far away from the rotating ring 82 through a thread. The swivel 82 is an important structural support that the ring body 81 can turn over, the rubber layer 83 can improve the sealing effect of the lantern ring 8 and the valve 9, and after the ring body 81 is sleeved, the bolt 84 can be screwed to ensure the tightness of the sleeving of the lantern ring 8.

As shown in figure 4, the number of the supporting legs 1 is four, the four supporting legs 1 are respectively positioned around the bottom surface of the water tank 2, and the bottom surfaces of the four supporting legs 1 are positioned on the same horizontal plane. Through the design that adopts supporting leg 1 respectively around 2 bottom surfaces of basin to the bottom surface of four supporting legs 1 is on same horizontal plane, makes supporting leg 1 not only can provide the effort of support for the device, can also ensure the stability of device self.
