Drain valve lightly-pressing structure, closestool drain valve key and closestool
The invention discloses a drain valve lightly-pressing structure, a closestool drain valve key and a closestool. The drain valve lightly-pressing structure comprises a pressing rod, a transmission mechanism and a driving rod. The transmission mechanism is provided with a first transmission part, a second transmission part and a third transmission part, and the linear speed of the first transmission part is lower than the transmission linear speed of the second transmission part; the driving rod is at least provided with a starting section and a rear section, the starting section is provided with a first driving part, and the rear section is provided with a second driving part; the first transmission part is connected with the first driving part of the driving rod, the second transmission part is connected with the second driving part of the driving rod, and the third transmission part is connected with the pressing rod. At least two sets of transmission structures with different transmission parameters are arranged on the drain valve light pressing structure, slow light pressing of the initial pressing section of the drain valve is achieved, fast pressing of the rear half section of the drain valve is achieved, and it is guaranteed that under the condition that the total stroke of the drain valve is not changed, the situation that the drain valve fails due to the fact that the pressing stroke is not enough is avoided; meanwhile, the pressing force value of the drain valve is effectively reduced, and the light pressing function of the drain valve is achieved.
本发明公开了排水阀轻按结构、马桶排水阀按键及马桶，排水阀轻按结构包括：压杆、传动机构及驱动杆；传动机构具有第一传动部、第二传动部及第三传动部，第一传动部的线速度比第二传动部的传动线速度慢；驱动杆至少具有起始段和后段，起始段上设有第一驱动部，后段设有第二驱动部；第一传动部连接驱动杆的第一驱动部，第二传动连接驱动杆的第二驱动部，第三传动部连接所述压杆。本发明通过在排水阀轻按结构设置至少两组不同传动参数的传动结构实现排水阀起始按压段慢速轻按，后半段快速按压，保证排水阀在总行程不变的情况下，不会因按压行程不够导致排水阀未挂住浮筒摆杆而失效，同时有效降低排水阀的按压力值，实现排水阀轻按功能。
