Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the utility model.
As shown in Figure 1, a kind of air respiratorresuscitator by floater seal, includes the sealing base 5 equipped with channel, described
The outer end in channel is sealed and installed with upper cover 1, and oily filter cylinder 4 is fixedly connected at the inner port in the channel, in the channel
It is sealed and installed with the fluted body lower cover 3 of outward opening, plate air filtering layer 6 is installed in the groove port of the lower cover 3,
3 bottom of the lower cover is provided with floating ball structure 2；
In conjunction with Fig. 2 as can be seen that the floating ball structure 2 includes the gland 22 of fluted body, the gland 22 tips upside down on described
On the bottom surface of lower cover 3, the edge of the gland 22 is connect with the sealing bottom surface of the lower cover 3, the company of being equipped in the gland 22
One end of extension bar 25, the connecting rod 25 is pierced by the bottom surface of the lower cover 3 and is connected with floating ball 27, the connecting rod 25 with it is described
Lower cover 3 is slidably matched；The other end of the connecting rod 25 is installed with baffle 24, the upper and lower ends face of the baffle 24 respectively with institute
The bottom surface for stating gland 22 is parallel with the bottom surface of lower cover 3, and the gear is corresponded on the bottom surface of the upper and lower lid in the bottom surface of the gland 22 3
The position of plate 24 offers oil gas through-hole 7, and gasket 23, the gasket 23 are installed on the end face of the baffle 24
Between the baffle 24 and the bottom surface of the gland 22, gasket 23 can be by the oil gas through-hole on gland compared to 24 face of baffle
7 sealings it is more tight；
When 24 block of the baffle is on the bottom surface of the gland 22, the upper surface of the baffle 24 passes through gasket 23
It is bonded with the bottom surface of the gland 22, the oil gas through-hole 7 on the gland 22 is located at the middle part of the baffle 24, in this way, baffle
24 and gasket 23 to the better tightness of oil gas through-hole 7, make the 7 not easy oil leakage oil gas of oil gas through-hole on gland 22；When described
When on the bottom surface of the lower cover 3, the lower face of the baffle 24 is bonded 24 block of baffle with the bottom surface of the lower cover 3, described
Oil gas through-hole 7 on lower cover 3 is located at the edge of the baffle 24, and baffle 24 is made to have at the oil gas through-hole 7 that can block lower cover 3
When splashing the function of fluid, while making the hydraulic oil being added into fuel tank by the utility model, hydraulic oil is more easy to pass through baffle
Gap between 24 and lower cover 3 enters the oil gas through-hole 7 of lower cover 3；
Kink has bearing 26, the bearing 26 to be fixedly connected on the outer wall of the lower cover 3 in the connecting rod 25, axis
Hold the stability of 26 guarantee connecting rods 25 movement；The connecting rod 25 is flexibly connected with floating ball 27, and floating ball 27 has certain swing
