Description
Technical field
The present invention relates to energy-saving lavatory technical field, specially a kind of novel energy-conserving automatic flushing formula toilet seat.
Background technique
Closestool is also toilet seat, is the bucket for having lid of stool and urine, and the invention of closestool is referred to as a great invention, it
It solves the problems, such as that the disengaging spread is drawn in people itself food and drink, evolved as again utilize siphon, spiral siphon later, present newest spray
The water closet for penetrating the principles such as hydrocone type and super rotation hydrocone type, also it is believed that water closet is cause of all kinds of wickedness, because it is consumed
A large amount of domestic water, current most water closet directly by clean tap water access water tank, need to consume daily
Take a large amount of cleaning water source still not having although each water consumption can be limited within 4 liters by novel economical toilet
It solves the problems, such as to rinse closestool using cleaning water source.
Set forth above in order to solve the problems, such as, application No. is a kind of disjunctors of " CN201110395104.3 " in the prior art
Toilet flushes, closestool, hand basin and flushing valve, hand washing tap, effluent switch and connecting pipe including disjunctor, connecting tube
Road includes flush toilets pipeline, hand basin drainage pipeline, connecting pipe C and connecting pipe D, and there are three interfaces to distinguish for flushing valve tool
Connect with water inlet line, flush toilets pipeline and connecting pipe C, effluent switch tool there are two interface respectively with water inlet line and company
The D connection of adapter tube road, hand washing tap are connected with connecting pipe C by check valve A, and hand washing tap and connecting pipe D pass through check valve B
It connects, the opening direction of check valve A, B are directed toward hand washing tap water discharging direction, and hand basin drainage pipeline connects downwards flush toilets pipe
The advantages of road, above structure is: simplified pipeline distribution, water-saving, deodorization, flushing effect are good, easy to operate；It is also exactly to use
One-way valve structures are simple, and accessory is few, long service life, and sealing effect is good.
Although solving the problems, such as cleaning water source flushing toilet, the above-mentioned Interconnected-closestool flushing system is in use
There are still more apparent defects: 1, there is still a need for the unlatchings that valve is carried out with hand and the pressing of closestool to rush after user goes to the toilet
It washes, the degree of automation is not high；2, usual not lid toilet lid, is easy to cause the diffusion of bacterium and peculiar smell, shadow after user goes to the toilet
Ring the cleaning in lavatory.
