CN205024796U - Negative pressure formula water -saving pedestal pan that breathes in - Google Patents

Abstract

The utility model discloses a negative pressure formula water -saving pedestal pan that breathes in, including closestool body, negative pressure bottle, blow off pipe and U type pipe, downward and vertical the placing of the bottleneck of negative pressure bottle, the drain in the closestool body is located through pipe connection U type pipe, keeps away from one end exit sealing connection blow off pipe and the blow off pipe top surface of junction and the sealed intercommunication of bottleneck of negative pressure bottle of drain at U type pipe. This negative pressure formula water -saving pedestal pan that breathes in has added a negative pressure bottle at U type pipeline top position, when the bottleneck process of invering is followed to liquid, the pressure of bottleneck department will reduce, the inside and outside negative pressure that forms of bottle, atmosphere pressure forces partly liquid to get into in the negative pressure bottle, the velocity of flow is accelerated in impelling the blow off pipe, because the existence of excrement and urine solids, the air can get into the negative pressure bottle frequently, partly liquid flows out in impelling the bottle, thereby form the circulation of " suction - outflow " state, make the blowdown ability strengthen, thereby reach the function of more economizing on water and prevent pipe blockage.

Description

A kind of suction type air suction water-saving water closet

Technical field

The utility model relates to water closet technical field, is specially a kind of suction type air suction water-saving water closet.

Background technology

In today of freshwater resources day by day shortage, " using water wisely " has been risen to the key subjects of the relation people's livelihood by habits and customs problem, the structure difference of the various toilet that brand is numerous in the market owing to producing, so also there is difference in the function of water saving, such as ideal " hydrocone type water-saving toilet pan " reaches the life requirement of " quiet odorless of keeping a public place clean " substantially, but most products of this water closet each with hourly water consumption still more than 6 liters, compare water wasting comparatively speaking, waste water resource, and easily block during bath, for this reason, we propose a kind of suction type air suction water-saving water closet.

Utility model content

The purpose of this utility model is to provide a kind of suction type air suction water-saving water closet, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme:

A kind of suction type air suction water-saving water closet, comprise closestool body, negative pressure bottle, blow-off pipe and U-tube, the bottleneck of negative pressure bottle downwards and vertically place, sewage draining exit place in closestool body connects U-tube by pipeline, is communicated with away from be tightly connected blow-off pipe and the blow-off pipe end face of junction of the exit, one end of sewage draining exit in U-tube with the bottle sealing of negative pressure bottle.

Preferably, screen pack is provided with between the bottleneck inwall of described negative pressure bottle.

Preferably, the inwall of described negative pressure bottle is smooth surface, and the bottleneck of negative pressure bottle and blow-off pipe junction adopt arc transition.

Preferably, the top of described negative pressure bottle is communicated with pressurizing unit by wireway.

Preferably, described pressurizing unit is the air bag be made up of rubber.

Compared with prior art, the beneficial effects of the utility model are: this suction type air suction water-saving water closet has added a negative pressure bottle at U-tube road tip position, from the principle of fluid pressure and flow velocity, when liquid from inverted bottleneck through out-of-date, the pressure of bottle mouth position will reduce, bottle is inside and outside forms negative pressure, atmospheric pressure forces a part of liquid to enter in negative pressure bottle, flow velocity in blow-off pipe is impelled to accelerate, due to the existence of faecal solids thing, air can enter negative pressure bottle frequently, a part of liquid in bottle is impelled to flow out, thus form " suck-flow out " cycle of states, pollution discharge capability is strengthened, thus reach the function of more economizing on water and prevent line clogging.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

In figure: 1, closestool body, 2, negative pressure bottle, 3, blow-off pipe, 4, U-tube, 5, pressurizing unit.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of suction type air suction water-saving water closet, comprise closestool body 1, negative pressure bottle 2, blow-off pipe 3 and U-tube 4, sewage draining exit place in closestool body 1 connects U-tube 4 by pipeline, be communicated with the bottle sealing of negative pressure bottle 2 away from be tightly connected blow-off pipe 3 and blow-off pipe 3 end face of junction of the exit, one end of sewage draining exit in U-tube 4, the bottleneck of negative pressure bottle 2 downwards and vertically place and be communicated with blow-off pipe 3, be provided with screen pack between the bottleneck inwall of negative pressure bottle 2 to result in blockage for preventing larger particle from entering in negative pressure bottle 2, the inwall of negative pressure bottle 2 is smooth surface, and the bottleneck of negative pressure bottle 2 and blow-off pipe 3 junction adopt arc transition, for smooth surface and bottleneck adopt the foreign material that bottle interior is convenient in arc transition design to discharge in negative pressure bottle 2, prevent from piling up, the top of negative pressure bottle 2 is communicated with pressurizing unit 5 by wireway, pressurizing unit 5 is the air bag be made up of rubber, when negative pressure bottle 2 bottleneck is blocked, pressurizing unit 5 can be extruded obstruction is poured blow-off pipe 3 and discharge.

This suction type air suction water-saving water closet has added a negative pressure bottle 2 at U-tube 4 tip position, from the principle of fluid pressure and flow velocity, when liquid from inverted bottleneck through out-of-date, the pressure of bottle mouth position will reduce, negative pressure bottle is inside and outside forms negative pressure, atmospheric pressure forces a part of liquid to enter in negative pressure bottle, flow velocity in blow-off pipe is impelled to accelerate, pollution discharge capability is strengthened, thus reach the function of more economizing on water and prevent line clogging, due to the existence of faecal solids thing, air can enter negative pressure bottle frequently, a part of liquid in bottle is impelled to flow out, thus form " suck-flow out " cycle of states.

Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
