It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Referring to fig. 1-3, a leakage-proof drainer comprises a drainer body 1, wherein the drainer body 1 comprises a first chamber 11, a second chamber 12, a third chamber 13 and a fourth chamber 14, each chamber is communicated with the other chamber through a communicating pipe 2, a downpipe 3 is further arranged on the first chamber 11, the downpipe 3 is communicated into the first chamber 11, a leakage-proof device 4 is fixedly arranged on a liquid discharge port of the drainer body 1, a drain pipe 5 is arranged at a liquid discharge port 41 of the leakage-proof device 4, and a leakage-proof mechanism 6 is further included, the leakage-proof mechanism 6 is fixed in the first chamber 11 and is fixedly connected with the communicating pipe in the first chamber 11, and is used for opening and closing the communicating pipe. By adding the leakage-proof mechanism 6 in the first chamber 11 of the drainer body 1, double protection is formed with the end leakage-proof device 4, and gas leakage is prevented. The leakage preventing device 4 in this embodiment is originally a device provided in the drainer itself, and for the prior art, the structure and the operation principle are not described in this application.

In this embodiment, the leakage preventing mechanism 6 includes a floating ball 61, a lever 62, a submerged valve 63, and a mounting seat 64, the mounting seat 64 is fixed on the inner wall of the first chamber 11, the lever 62 is movably disposed on the mounting seat 64 by a pin, one end of the lever 62 is fixedly disposed with the floating ball 61, the other end thereof is fixedly disposed with the submerged valve 63, the submerged valve 63 is opened and closed by the ascending and descending of the floating ball 61, and the submerged valve 63 is disposed inside the communicating pipe 2. The leakage-proof mechanism 6 utilizes the liquid level difference to make the floating ball 61 open and close the submerged valve 63 under the action of buoyancy and gravity; when the gas pressure is too high or the liquid level is reduced due to water shortage, the floating ball 61 is reduced under the action of gravity, the submerged valve 63 is closed, gas leakage is prevented, sealing is more reliable when the pressure is higher, and the pressure can reach 1.0 MPa; when the water level rises, the submerged valve 63 is opened under the action of the buoyancy of the floating ball 61, and the drainer drains water.

In this embodiment, the submerged valve 63 includes a valve body 631, a main valve core 632, an auxiliary valve core 633 and a sealing ring 634, the valve body 631 is disposed inside the communication pipe 2, the main valve core 632 is located inside the valve body 631, a through hole is formed in the valve core, the auxiliary valve core 633 is fixed on the lever 62, the auxiliary valve core 633 is matched with the main valve core 632 to abut against the through hole of the main valve core 632, and the sealing ring 634 is disposed between the main valve core 632 and the communication pipe 2 for sealing.

In this embodiment, the fulcrum of the lever 62 is located at an end away from the float 62. Through the amplification effect of the lever 62, the buoyancy and the gravity of the floating ball 61 are multiplied to open and close the submerged valve 63, so that the submerged valve 63 is more reliably sealed when closed and is lighter when opened, and the phenomenon that the submerged valve cannot be opened due to overlarge resistance is prevented.
