Abstract
The invention provides a foam generating device. The technical field is that: the invention belongs to a bathroom industry and relates to a foaming device, in particular to a foam generating device which is used for preventing a toilet from sputtering buttocks and avoiding emitting odor. The invention discloses the foam generating device which does not need electric energy and has a simple structure. The device takes a similar-venturi tube structure as a core and can take a tap water flow as the whole power, so as to realize that three components including air, water and foaming liquid are sufficiently mixed to finally form fine foams. The device solves the problem that the existing similar equipment needs complicated parts including electric energy, an air pump, a dispersing body, a foaming box and the like. Meanwhile, the device can be easily installed on a common toilet to be directly used and expands a use range of a foam-covering odor preventing method in a bathroom field.
Description
Technical field
The invention belongs to the bathroom industry, relate to a kind of foam device, relate in particular to a kind of for preventing that closet from spattering stern and the foam-making apparatus that gives an offensive smell and use.
Background technology
The water closet that trap is arranged at present; Pan all requires to possess the above water seal of 50mm, and the function of isolating pipelines peculiar smell is played in this water seal, and a ubiquitous stern problem of spattering---excreta falls into the spray that splashes after the water seal but also have; Make us very detesting, and bring bigger hygienic risk.In addition, common closet can distribute foul smell always in people's discharge process, make us unhappy.One of solution to this problem be with foam coverage in sanitary equipment, utilize its penetrability and barrier, thereby preventing that spray from splashing distributes with foul smell.Also there is patent to propose the method for in closet, using foam to economize on water, objectively says and also played splashproof stern and separated smelly effect.
More than all these methods all relate to the foam that will prepare a large amount of exquisitenesses fast.The patent of the overwhelming majority and product are like 200510117333.3 (foam type water saving toilets); (200520058382.x the energy-conservation flushing urinating bucket of foam type); (200520097919.3 toilet, the instant generator of urinal foam); (200520128981.4 the water closet that attaches foam-making apparatus), 200720128797.9 (toilet foam-generating devices and contain the toilet of toilet foam-generating device), 200920222973.4 (a kind of foam odor formula pans); The principle that its foaming produces is utilizes air pump to produce compressed air, produces bubble thereby through air conduit compressed air is imported the dispersion with fine pore size again.This foam producing method needs electric energy, and equipment is many, is not easy to installation and maintenance.Simultaneously, these foam devices have held blowing agent and the water that mixes since also needing the bigger foam box of volume to use, and this has also increased equipment volume and cost.In addition, air pump service time also can produce flow after long and reduce problem.Secondly, dispersion can be stopped up because foam solution sticks gradually, could use after needing to clean.
Application number is that the foam closet that the patent of 200720055617.9 (the toilet foam is towards dropping control devices) relates to is the water closet with trap; In order to produce and discharge foam; Need on the closet body, do bigger structural modification, and not consider and how foamite system is directly used on already installed common closet.
Application number is 99200682.1 the compressed-air actuated method generation of the manual generation of toilet foam producer patent end user foam, and the people that this method obviously is not suitable for will going to toilet uses at once.
The present invention has fundamentally solved above-mentioned these problems; Providing a kind of does not need electric energy or only needs little power; Do not need parts such as air pump, dispersion, foam box just can produce the equipment of required foam; Especially, the present device occasion that can be directly installed on most of closet or have this type of to need.
In addition, the inventive method adopted with fire-fighting with the approaching Venturi tube effect of air-foam fire extinguisher principle, but great difference is all arranged on structure design, application target and service condition with it:
1, the air generator used of fire-fighting; Must use specific blowing agent---reach the fire extinguishing purpose like protide blowing agent, fluorocarbon surfactant etc.; And the used blowing agent of the present invention can be the surfactant of any kind of; Especially the family expenses liquid detergent class surfactant that is easy to get, the purpose of its foaming are to prevent that spray spatters stern and separated smelly in the closet, rather than fire extinguishing.
2, air-foam fire extinguisher is used in fire-fighting; Generally needing hydraulic pressure to reach 0.3MP could use, and therefore must use the water pump pressurization, and the required minimum hydraulic pressure of present device is merely 0.05MP; The tap water of minimum pressure just can satisfy the foaming requirement, does not need a series of supporting equipment such as power supply, water pump.
3, the air generator bulky used of fire-fighting, and product involved in the present invention bubble equipment volume is minimum, can be installed in easily on any common closet.
Summary of the invention
The present invention proposes a kind of device that produces foam, and purpose is: do not needing electric energy or only needing little power, do not needing to utilize the power of tap water just can prepare the foam that meets instructions for use under the situation of parts such as air pump, dispersion, foam box.Simultaneously, this device can easily be installed on the common closet and directly use.
Technical scheme of the present invention:
A kind of foam-making apparatus especially refers to comprise for preventing that closet from spattering stern and the foam-making apparatus that gives an offensive smell and use,
