Flush valve and closestool
The invention discloses a flush valve and a closestool, and relates to the technical field of sanitary ware. The flushing valve comprises a valve body and an anti-siphon structure, a cavity is formed in the valve body, the valve body is further provided with a water inlet end and a water outlet end which are communicated with the cavity, a ventilation notch is formed in the end face of the water outlet end, and an air inlet channel communicated with the ventilation notch is further formed in the outer wall face of the water outlet end; the anti-siphon structure comprises a connector and a sealing piece, the connector is connected to the outer wall face of the water outlet end in a sleeving mode, and the sealing piece is fixed to the inner wall of the connector. The sealing piece has a first state that the sealing piece abuts against the outer wall face of the water outlet end to seal the air inlet channel, or the sealing piece has a second state that the sealing piece is separated from the outer wall face of the water outlet end to open the air inlet channel, and in the second state, outside air can enter the valve body through the air inlet channel and the ventilation notch. According to the technical scheme, the anti-siphon structure of the flush valve is simplified, and the stability of the flush valve is improved.
本发明公开一种冲洗阀和马桶，涉及卫浴洁具技术领域。该冲洗阀包括阀体和防虹吸结构，所述阀体内部形成有腔体，所述阀体还具有分别连通腔体的进水端和出水端，出水端的端面形成有透气缺口，出水端的外壁面还形成有连通所述透气缺口的进气通道；防虹吸结构包括连接头和密封件，连接头套接在所述出水端的外壁面，密封件固定在连接头的内壁；密封件具有与出水端的外壁面抵接以密封所述进气通道的第一状态，或者所述密封件具有与述出水端的外壁面分离以打开所述进气通道的第二状态，在第二状态下，外界空气可经由进气通道和透气缺口进入阀体内。本发明技术方案旨在简化冲洗阀的防虹吸结构，提升冲洗阀稳定性。
