1. The utility model provides a special exhaust closestool valve in bathroom field, includes closestool siphon pipeline, characterized by: the outlet of the end face of the rubber valve on the wall of the toilet bowl is tightly close to the elastic flat rubber tube and is parallel to the wall of the toilet bowl.

Technical Field

The invention relates to a closestool air valve in the field of bathrooms.

Background

Chinese patents CN102926450B, CN103114632B, CN106812197B, CN107514037B and CN106400923B adopt siphon pipes for exhausting gas at the rear part of the toilet, and compared with the structure in which exhaust nozzles of CN101476344B, CN102912839B, CN106337482B, CN109339173B and CN110273455A are arranged at the front part of the toilet pipe, the installation and maintenance are more convenient, the structure is simpler and the cost is lower. The common valve and the exhaust pipe opening of the exhaust toilet are arranged close to the toilet pipe wall, and are particularly easy to be blocked by dirt to cause failure, so that the valve fails to work, air is leaked, and the exhaust pipe opening is blocked by scaling and needs to be repaired frequently; especially, the valve on the exhaust pipeline is far away from the siphon wall, which seriously affects the siphon effect of the closestool and causes insufficient suction and water waste. The intelligent closestool for exhausting of the existing practical commodity selects a catalyst adsorption mode to filter the peculiar smell air firstly and then return the air to the room, so that the failure filter element must be replaced in time to exhaust and purify thoroughly.

Disclosure of Invention

The technical problem solved by the invention is as follows: the automatic air-discharging closestool has the advantages that specific rubber valves are arranged on the pipe wall of the air-discharging closestool to flexibly control air discharge and seal the pipe orifice, flushing and air discharge of a closestool siphon pipeline are smooth, practical and reliable, dirty air in the closestool pipeline is prevented from leaking, and waste water resources caused by functional failure of the siphon pipeline are avoided.

The technical scheme of the invention is as follows: the utility model provides a special exhaust closestool valve in bathroom field, includes closestool siphon pipeline, characterized by: the outlet of the end face of the rubber valve on the wall of the toilet bowl is tightly close to the elastic flat rubber tube and is parallel to the wall of the toilet bowl.

The invention has the beneficial effects that: the valve performance stability is ensured to be good, the sewage and waste gas flow is smooth, the cavity of the siphon pipe wall can be avoided, the reverse smell of the siphon pipe can be prevented from leaking, the function of the exhaust closestool is comprehensively improved, the product quality is improved, and the simple, reliable and durable excellent effect of matching the closestool exhaust device is realized.

FIG. 1 is a rubber valve; 2 siphon wall; 3 a siphon pipeline; 4, an air inlet joint; 5, an air valve end face; 6 flat rubber tube。

Detailed Description

Referring to the attached drawings, a rubber air valve 1 is arranged on the siphon wall 2 at the rear part of the closestool, an outlet joint of an exhaust pipeline of the closestool is connected with an air inlet joint 4 of a siphon pipeline 3, an elastic flat rubber tube 6 on the end surface 5 of the air valve of the closestool tightly blocks the air in the siphon pipeline 3 from escaping at ordinary times, and the elastic flat rubber tube 6 expands the air to be conveyed into the siphon pipeline when the closestool exhausts air.
