Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1 to 3, a lifting mechanism of a drain valve includes:

a body 10 provided with a water outlet;

the valve core 20 is movably arranged in the body 10, and the upper end of the valve core 20 is provided with a butting part 21;

a driving unit movably mounted on the body 10 and provided with a driving part 31;

the driving portion 31 is in abutting transmission fit with the abutting portion 21, and the driving unit drives the valve element 20 to move vertically so as to open and close the water outlet.

In this embodiment, the driving unit includes a swing lever 30 rotatably attached to the body 10, and the driving portion 31 is provided on the swing lever 30.

In this embodiment, the driving unit further includes a key 40 movably attached to the body 10, one end of the swing link 30 is located below the key 40, and the other end of the swing link 30 is located below the abutting portion 21.

In this embodiment, the keys 40 include a large row of keys 40a40 and a small row of keys 40b 40.

In this embodiment, the driving portion 31 is a mounting groove provided on the swing link 30, and the abutting portion 21 and the mounting groove are in limited fit in the circumferential direction of the body 10.

In this embodiment, the swing link 30 is a closed ring structure.

In this embodiment, the valve element 20 includes a central shaft 20a vertically disposed, and the abutting portion 21 is disposed at an upper end of the central shaft 20 a.

In this embodiment, the abutting portion 21 is an extension arm provided perpendicular to the central axis 20 a.

In this embodiment, the valve core 20 further includes a sealing disc 20b for opening or closing the water outlet, specifically, the central shaft 20a and the sealing disc 20b are clamped and fixedly engaged, but the central shaft 20a and the sealing disc 20b may also be integrally formed.
