Water drain valve with half exhaust device capable of being separated from full exhaust device

Abstract

The invention discloses a water drain valve with a half exhaust device capable of being separated from a full exhaust device, which includes a half exhaust device, a full exhaust device, a half exhaust lifting mechanism, a full exhaust lifting mechanism, an inner core tube and a drain seat; The half exhaust lifting mechanism and the full exhaust lifting mechanism are respectively arranged on the top of the inner core tube for lifting the inner core tube, and the bottom of the inner core tube and the bottom of the drain seat form a water seal. The full exhaust device passes through and sleeveson the inner core tube and is fixed on the drain seat, a full exhaust limit fitting is formed between the full exhaust device and the drain seat; the half exhaust device passes through and sleeves onthe inner core tube and is arranged above the full exhaust device. The half exhaust device is movably clamped with the full exhaust device so that the half exhaust device can be mounted on and removedfrom the inner core tube, and a half exhaust limit fitting is formed between the half exhaust device and the inner core tube. The valve has the advantages of flexible structure, convenient disassembly and installation, and is suitable for a hidden water tank.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a drain valve in which a half row device is detachable from a full row device. Background technique [0002] With the continuous updating and progress of the bathroom field, people pay more and more attention to the appearance of the water tank while it has the drainage function, especially the hidden water tank. For the sake of beauty, the design of the installation channel (hereinafter referred to as "side port") It is usually relatively small, so the drain valve that is disassembled through the side port often faces the problem of difficulty in taking it out. For example, patent 201510886945.2 discloses an inner core tube control device for a drain valve, which includes a drain valve body, an inner core tube, and a buoy. Bucket, the overall structure of the drain valve body has to be expanded accordingly, resulting in a larger drain valve body, which also means that the disassemb...

[0002] With the continuous updating and progress of the bathroom field, people pay more and more attention to the appearance of the water tank while it has the drainage function, especially the hidden water tank. For the sake of beauty, the design of the installation channel (hereinafter referred to as "side port") Usually relatively small, so the drain valve that is disassembled through the side port often faces the problem of difficult removal

For example, patent 201510886945.2 discloses an inner core tube control device for a drain valve, which includes a drain valve body, an inner core tube, and a buoy. Bucket, the overall structure of the drain valve body has to be expanded accordingly, resulting in a larger drain valve body, which also means that the disassembly and assembly of the drain valve is more difficult, and even the drain valve cannot be taken out from the side port.
