Problems solved by technology

When the button is pressed down and the water stop mechanism is initially raised, the water flow enters the valve body of the drain valve from the water tank through the opening 2' of the base 1', and the top surface of the water sealing part of the water stop mechanism is subjected to the pressure in the water tank. Due to the hydraulic pressure of the water, when the water stop mechanism rises when the button is pressed manually, it needs to overcome the momentum of the water flow and the pressure of the water flow in the water tank, which increases the burden of pressing the button

Embodiment 1

[0036] Embodiment one, see Figure 2 to Figure 10 As shown, a soft-touch drain valve of the present invention includes a valve body 1, a base 2, a water stop mechanism 3 and a control mechanism 4. The valve body 1 is installed on the base 2, and the base 2 is provided with a side To the water inlet opening 8 and the water outlet 22, the valve body 1 is correspondingly provided with an inner chamber for accommodating a water stop mechanism 3, and the water stop mechanism 3 is movably socketed in the valve body 1, and the water stop mechanism 3 driven by the control mechanism 4 to rise. The present invention also includes a cover 7 , which is an annular structure, sleeved on the water stop mechanism 3 and located inside the lateral water inlet opening 8 of the base 2 . The cover 7 is driven to move by the water stop mechanism 3. When the drain valve is not draining, the cover 7 closes the lateral water inlet opening 8 of the base 2; when the water stop mechanism 3 rises from th...

Embodiment 2

[0045] Embodiment two, see Figure 11 to Figure 13 As shown, the soft-touch drain valve of the present invention differs from Embodiment 1 in that: the top surface of the water sealing part 32 of the water stop mechanism 3 is provided with a positioning rib 321, and the positioning rib 321 is connected to the The rib 73 of the cover 7 cooperates, and the height of the positioning rib 321 is not greater than the height difference between the top surface of the water sealing part 32 of the water stop mechanism 3 and the lower end surface of the rib 73 of the cover 7 . Then when the water stop mechanism is in a static state, there is a certain gap between the supporting rib 73 of the cover 7 and the positioning rib 321 of the water stop mechanism 3, as Figure 12 As shown, the water stop mechanism does not interact with the cover, which ensures the tightness of the drain valve. When the water stop mechanism 3 rises until the positioning rib 321 is in contact with the support rib...

Abstract

The invention discloses a touch drain valve and a method for reducing pressing force of the drain valve. The touch drain valve comprises a valve body, a pedestal, a water stopping mechanism and a control mechanism, wherein the valve body is mounted on the pedestal; a lateral water inlet and a water outlet are formed in the pedestal; a cavity for accommodating the water stopping mechanism is formed in the valve body correspondingly; the water stopping mechanism is movably sleeved and connected with the valve body; the water stopping mechanism is driven by the control mechanism to rise; during water stopping, the bottom surface of the water stopping mechanism is hermetically clung to the water outlet; the touch drain valve further comprises a cover; the cover is of an annular structure and is in movable sleeve joint with the pedestal; the cover is driven by the water stopping mechanism or a single driving mechanism to move; when the drain valve stops draining water, the cover can be used to seal the lateral water inlet of the pedestal. In the invention, the cover is added at the lateral water inlet of the pedestal, and in the initial rising phase of the water stopping mechanism, the cover can shield the lateral water inlet of the pedestal in order to prevent the upper end face of the water stopping mechanism from being influenced by water stream in the lifting process; a swing arm structure is optimized to increase the ratio of the actuating arm to the lifting arm of the swing arm; on the premise of ensuring the invariability of the pressing travel, the pressing force is reduced obviously.

Description

technical field [0001] The invention relates to a drain valve, in particular to a soft-touch drain valve capable of reducing pressing force and a method for using the drain valve to reduce the pressing force of the drain valve. Background technique [0002] The conventional drain valve uses the push button lever to press the driving arm of the swing arm to move downward. According to the principle of leverage, the driving arm of the swing arm goes down, and the lifting arm of the swing arm rises, driving the water stop mechanism to rise, and the water in the water tank passes through the base 1 The opening of '2' (eg figure 1 shown) enters the valve body and flows into the flushing pipe through the drain port of the base 1'. When the button is pressed down and the water stop mechanism is initially raised, the water flow enters the valve body of the drain valve through the opening 2' of the base 1' from the water tank, and the top surface of the water sealing part of the wat...
