Abstract
The utility model discloses a manual negative pressure aspirator, which has the characteristics of simple structure, low cost and long service life, and the characteristic that the manual negative pressure aspirator is especially adapted to be used in the common family. The manual negative pressure aspirator contains an air aspirating tube, a one-way valve, a soft tube, a liquid tank and an aspirating head. A one-way leather bowl is provided on the front end of the pull handle to form the air aspirating tube together with a cylinder tube, which are connected with a handgrip; a spring is provided between the leather bowl and the handgrip; one end of the one-way valve composed of the spring and a ball is provided on the front end of the air aspirating tube, and the other end is provided with a joint; the air aspirating tube, the outlet and the inlet of the liquid tank are connected with the aspirating head together by the soft tube. The manual negative pressure aspirator can be used for aspirating the liquids of the baby or the old man having no ability of independent activity, such as nasal discharge, tears and sputum, etc. The manual negative pressure aspirator also can be used for aspirating the residual liquid which is not easy to be poured in the container.
Description
Technical field:
This utility model relates to family daily life articles for use technical field, and exactly, it is a kind of manual negative pressure-pumping device that is used to aspirate the baby or does not have autonomic activities ability old man's fraction such as nasal mucus, tear and sputum.
Background technology:
In our daily life through regular meeting run into need the suction small amount of liquid in, particularly nasal mucus and tear overflow morely when the baby catches a cold, people are generally with handkerchief or toilet paper wiping, this mode easy damaged nasal mucosa.The old man who does not have the autonomic activities ability in addition, fraction such as nasal mucus, tear and sputum also be very reluctant problem.Carry out wiping with toilet paper and can solve some problems to a certain extent, but think, gently then do not deal with problems during wiping in the person's of receiving aid angle, heavy then can cause the damage of human body skin; Especially the secretions in nostril, canthus or the oral cavity is to finish with the method for toilet paper wiping.So, a kind of small-sized, simple in structure, easy to use, be suitable for the liquid aspirator tool that family uses, be that people wish the family daily life articles for use that obtain always.In recent years, a lot of innovation and creation are appearring aspect the small-sized suction pump, as Chinese patent 01134810.0 disclosed portable suction unit, though it is small and exquisite, portable, can be fit to family uses, but battery-driven negative pressure pump is arranged by two, increased the production and the use cost of suction pump, aspect safeguarding, also increased certain degree of difficulty.In addition, Chinese patent 86204108 and 03214825.9 also discloses pocket attraction respectively and has robbed and manual two kinds of utility model patents of continuous negative pressure suction pump, they have all adopted the method for manual manufacturing negative pressure, but rubber sacculus, reciprocating-piston and double check valve etc. still make the structure of suction pump seem comparatively complicated.
Summary of the invention:
The purpose of this utility model solves the deficiencies in the prior art exactly, and a kind of simple in structure, low cost of manufacture, long service life are provided, and particularly adapts to the manual negative pressure-pumping device that average family uses.
The purpose of this utility model is to realize like this, manually the negative pressure-pumping device comprises pump bowl, check valve, flexible pipe, fluid reservoir and suction nozzle, unidirectional leather cup (8) is installed in the front end of handle (10), constitute pump bowl with cylinder barrel (9), and be connected on the handle (11), between leather cup (8) and the handle (11) spring (12) is housed, it is characterized in that: check valve one end of being made up of spring (7) and ball (4) is installed in the front end of pump bowl, the other end is equipped with joint (5), with flexible pipe (6) pump bowl and fluid reservoir (3) outlet are linked together, the inlet other end that flexible pipe (2) one ends connect fluid reservoir (3) links to each other with suction nozzle (1).
The utility model has the advantages that: check valve selects for use general part to get final product, and the pump bowl leather cup can utilize the unidirectional leather cup of similar bicycle pump leather cup, so its structure, manufacturing process are simple, cheap; Negative pressure pressure is easy to control, with after be convenient to cleaning, and its service life is longer relatively.
Description of drawings:
Fig. 1 is structure of the present utility model and connecting relation sketch map.
The specific embodiment:
Embodiment 1:
Most of part of the present utility model can be made with non-toxic plastic, check valve selects for use general stage clip and steel ball to get final product, the pump bowl leather cup can utilize the unidirectional leather cup of similar bicycle pump leather cup, answers the leather cup opening upwards during installation, by shown in the accompanying drawing parts is fitted together then.
During use suction nozzle is placed on the liquid that will aspirate, holds handle 11 and handle 10, and will shake hands gradually 10 to pull to handle 11, cause the space generation negative pressure under the leather cup; Under the effect of negative pressure, ball 4 leaves the port of joint 5, and through flexible pipe 6, fluid reservoir 3 and flexible pipe 2, the front end formation negative pressure at suction nozzle 1 is drawn onto liquid in the fluid reservoir 3.Decontrol handle 10, move downward at the effect down cup 8 of spring 12, negative pressure disappears, and ball 4 is shut the port of joint 5 under the effect of spring 7, guarantees that the liquid that can not in the pipeline flows backwards; Because the unidirectional opening of leather cup 8 upwards, the air of leather cup 8 lower space is discharged between leather cup 8 and cylinder barrel 9 inwalls.
