Meanwhile, the rotating shaft limiting parts 5 are arranged at the two ends of the handle rotating shaft 8, so that the handle rotating shaft 8 can be fixed, and the handle rotating shaft 8 is prevented from escaping and losing efficacy in use. The installed buckle 3 is hidden in the buckle groove 11 of the flip cover upper shell 1 and is integrated with the flip cover upper shell 1, so that the integrity of the appearance of the flip cover is maintained.

A jack catch cylinder 12 at one end of the jack catch 4 is penetrated with a spring 7 and passes through a round hole of a spring limiting plate 13 on the flip lower shell 2. The spring limiting plate 13 provides a limiting effect for the spring 7 and a guiding effect for the jaw 4. The flip lower shell 2 and the flip upper shell 1 are fixed together, the jaw poking plate 14 of the jaw 4 penetrates through the rectangular limiting hole 15 of the buckle groove 11, and the rectangular limiting hole 15 can limit the horizontal movement distance of the jaw poking plate 14. The jaw dialing plate 14 can contact with a buckle dialing plate 16 below the buckle 3, and when the outer part of the buckle 3 is pressed, the buckle 3 dials the jaw dialing plate 14 through the buckle dialing plate 16 to control the motion of the jaw 4. The handle groove 11 on the flip upper shell 1 and the groove for fixing the sealing rubber strip 6 on the flip lower shell 2 form a claw upper limiting bulge 17 and a claw lower limiting bulge 18 on the reverse side, and the claw 4 is limited in the space of the claw upper limiting bulge 17, the claw lower limiting bulge 18 and the rectangular limiting hole 15.

As shown in fig. 1-3, the flip hinge connector 9 is mounted on the flip fastener 10 of the flip lower housing 2, and the flip hinge 23 passes through the flip hinge connector 9 and is mounted on the tank housing 20, so that the entire flip can rotate around the flip hinge 23 along with the flip hinge connector 9, and the flip can rotate around the flip hinge 23 on the tank housing 20.

The flip fixing piece 10 is fixed on the flip lower shell 2, the flip rotating shaft connecting piece 9 is fixed on the flip fixing piece 10 and the flip lower shell 2, and the flip rotating shaft 23 passes through the flip rotating shaft connecting piece 9 and is installed on the water tank shell 20, so that the whole flip can rotate around the flip rotating shaft 23 along with the flip rotating shaft connecting piece 9.

As shown in fig. 3 and 4, the flip cover is closed and locked, when the flip cover is rotated and closed around the flip cover rotating shaft 23, the claw 4 will contact with the cistern housing 20, the position of the cistern housing 20 contacting the claw 4 has a guiding slope 21, and the bottom of the guiding slope 21 has a slot 22 for clamping the claw 4.

When the flip cover is in a locked state, the flip cover lower shell 2 extrudes the sealing rubber strip 6 on the water tank shell 20, and meanwhile, the water tank 19 and the water tank shell 20 are fixed together, so that the sealing rubber strip 6 seals the flip cover lower shell 2 and the water tank 19 together to form a closed space. Restarting the vacuum motor 24 on the water tank 19 will efficiently bring the water tank 19 into a vacuum state. In the whole closed locking process, the claw toggle plate 14 can be separated from the handle toggle plate 16 when the claw 4 moves towards the flip cover, so the handle 3 can not be influenced by the movement of the claw 4, the whole locking process is convenient and fast, and the handle 3 is always hidden in the handle groove 11 of the flip cover upper shell 1 and is integrated with the flip cover upper shell 1, so that the integrity of the appearance is kept.

As shown in fig. 3 and 5, the unlocking and opening process of the flip cover is that when the vacuum motor 24 stops working and the water tank 19 is depressurized, the outer side part of the handle 3 is pressed, the handle 3 rotates around the handle rotating shaft 8, the handle poking plate 16 pushes the jaw poking plate 14 to move the jaw 4 into the flip cover, and at this time, the jaw 4 and the spring limiting plate 13 compress the spring 7 on the jaw cylinder 12. When the claw toggle plate 14 contacts with the inner side edge of the rectangular limit hole 15, the turning of the buckle 3 reaches the limit, the claw 4 can be pushed out from the clamping groove 22 of the water tank shell 20, at this time, the inner side edge of the buckle 3 and the flip cover upper shell 1 form the largest gap, the flip cover is lifted upwards by pulling the inner side edge of the buckle 3, and the flip cover can be opened around the flip cover rotating shaft 23. When the buckle 3 is released, the claw poking plate 14 is not limited by the buckle poking plate 16 any more, the claw 4 is pushed to the outer side of the flip cover by the compressed spring 7, the claw poking plate 14 drives the buckle poking plate 16 to enable the buckle 3 and the flip cover upper shell 1 to be integrated, and the buckle 3 is hidden in the buckle groove 11 of the flip cover upper shell 1 again, so that the integrity of the appearance of the flip cover is maintained. The operation is convenient, and the hand-operated reset buckle 3 is not needed.

According to the invention, the flip cover and the water tank 19 can be locked by pressing the flip cover upper shell 1 downwards, the handle 3 does not need to be buckled, and the operation is convenient and quick. The hidden handle 3 is hidden in the flip cover in the locking process, and the integrity of the appearance is kept.
