Abstract
A pedal type inflatable shoe is especially suitable for being installed on an inflated facility for long-time continuous operation, such as a knapsack steel cylinder sprayer for spraying pesticide and foliar fertilizer. The sole of the inflatable shoe is provided with an air chamber consisting of an upper sole 10, a lower sole 3 and an annular wall 4, an elastic body 1 is arranged in the air chamber, the air chamber is communicated with the outside through an air suction valve 2 and is communicated with an inflated facility through an air exhaust valve 8 and a three-way joint 6. The kinetic energy of the person who continuously steps on and lifts up the foot during walking is utilized to drive the inflatable shoes to generate continuous inflation power. The utility model discloses simple structure, practicality have easy and simple to handle, laborsaving, aerify advantages such as efficient.
Description
The utility model is a kind of dynamic power machine utensil, specifically a kind of footwear that aerification function is arranged.
Common inflation utensil, as, inflate the inflator of usefulness to bicycle, give and bear utensil that steel cylinder formula sprayer inflates etc., be mostly a kind of push-and-pull piston structure, that is: hold the handle of utensil, the piston rod that piston is equipped with in push-and-pull is given the facility that is inflated inflation.For example, the peasant uses and bears steel cylinder formula sprayer when the crop spraying pesticide, at first repeatedly the push-and-pull piston rod is inflated in sprayer, when treating that air pressure is enough high, stops inflation, the beginning spraying pesticide, along with the prolongation of the time of spraying, the air pressure in the sprayer reduces gradually, sprays efficient and also decreases, by the time efficient when very low, must stop the work of spraying and inflate to sprayer again.Therefore the work of spraying can only be carried out by spells, not only bothersome, effort, and inefficiency.
The purpose of this utility model is the shortcoming that solves background technology, design a kind of completely newly laborsaving, save trouble, high efficiency inflation utensil.
The utility model is to realize like this.Design a kind of foot-operated inflation footwear, " sole " of inflation footwear be one by following sole, go up the air chamber that sole and annular wall constitute, this air chamber communicates with the external world by inlet valve, links to each other by air bleeding valve, tracheae, three-way connection and the equipment that is inflated.Dedusting filter screen of using and the elastomer that upper and lower sole is separated are housed in the air chamber.This air chamber can have half sole and two parts of the back palm, links to each other by the tube connector that presses down air valve is housed therebetween, thereby forms two stages of compression, improves output pressure.During use, the three-way connection one of this footwear is terminated on the facility that is inflated, the operator walks as the common footwear of wearing, and both feet are put on the inflation footwear earlier, and when planting oneself, the air chamber of sole is in compressive state under the pressure of human body.When marking time or walk: after lifting pin, air cavity is pressurized no longer, and elastomer sole is up and down pushed open, and rarefaction of air is negative pressure in the chamber, and outside air is pushed admission air valve open and entered air chamber, and when directly only the chamber inner and outer air pressure equated, admission air valve was closed automatically.When treating that this pin that lifts depresses once more, operator's body weight is added on the sole, the volume-diminished of air chamber, and gas pressure increases and air bleeding valve is pushed open, has realized being inflated the inflation of facility.So, the operator only needs walking freely or remains where one is, one falling together of every pin, finish the program of air-breathing → inflation → air-breathing → inflation again and again, two pin are strolled and are alternately walked, the compressed air of two footwear generations is replacing the valve by three-way connection, just can realize continuous charge to the facility that is inflated.When the air pressure that is inflated facility reaches certain when setting value, the air pressure of turnover air bleeding valve equates that drain tap will be closed automatically, and then drives air intake valve and close, no matter operator's walking or whether mark time after this, and gas replenishment process is ended; Wait that the air pressure in the equipment that is inflated is lower than when setting value, the inflation procedure of inflation footwear will be recovered automatically.That this foot-operated inflation footwear has is laborsaving, save trouble, high efficiency advantage.
Accompanying drawing 1 has been described an embodiment of the present utility model---give the front elevational schematic and the schematic top plan view of foot-operated inflation footwear bearing steel cylinder formula sprayer inflation usefulness.It is made up of the filter screen 1 that filters dust, inlet valve 2, time sole 3, last sole 10, annular wall 4, upper of a shoe 5, three-way connection 6, tracheae 7, air bleeding valve 8, plastic foam elastomer 9.Between the upper and lower sole, formed half sole, two air chambers of the back palm, connected by the tube connector 11 that presses down air valve is housed therebetween.Inlet valve communicates with the external world, by air bleeding valve, tracheae, three-way connection and bear steel cylinder formula sprayer and link to each other.During work, operator's back is equipped with the sprayer of agricultural chemicals, puts on foot-operated inflation footwear, strolls in the fields, and sprayer just sprays out continuously agricultural chemicals.
Claims (1)
1, a kind of foot-operated inflation footwear is characterized in that sole is an air chamber of being made up of last sole (10), following sole (3), annular wall (4), and this air chamber has two parts in half sole chamber and palm chamber, back, therebetween by tube connector (11) connection that presses down air valve is housed.The screen pack (1) of isolating dust is housed in the air chamber and makes the elastomer (1) of sole disengaging up and down, air chamber communicates with the external world by inlet valve (2), and air chamber is communicated with the facility that is inflated by air bleeding valve (8), tracheae (7), three-way connection (6).
