Abstract
The utility model discloses a vacuum cupping extracting gun which comprises a grip (1), a handle (2), an extracting cylinder (3), a piston rod (4), a piston and a return spring (4), wherein the handle (2) is connected with the piston rod (4) into a whole, the extracting cylinder (3) is fixedly connected with a joint at the lower part of the grip (1), the piston rod (4) and the piston are arranged in the extracting cylinder (4), the return spring (5) is arranged on the piston rod (4) at the upper part of the piston, the piston comprises an upper piston ring (6), a packing cup (8) and a lower piston ring (9), the upper piston ring (6) and the lower piston ring (9) are fixed on the piston rod (4), the packing cup (8) is movably sleeved on the neck part between the upper piston ring (6) and the lower piston ring (9), and at least one notch (7) is arranged on a positioning ring of the upper piston ring (6). After the structure is adopted, the problems of large piston return air resistance and low speed are solved. The utility model has the advantages of simple and reasonable structure, convenient and flexible use, high extraction speed, high efficiency and the like.
Description
Technical field
This utility model relates to a kind of air extractor, the vacuum suction rifle that uses on particularly a kind of traditional Chinese medical science cup health-care physiotherapeutic.
Background technology
In traditional Chinese physical therapy, generally treat various diseases with the method for cupping, tend to receive beyond thought effect, but in use, the easy skin ambustion of comburant, the size of negative pressure is difficult to control, the excessive easy injured skin of negative pressure in jar, the too small therapeutic effect of negative pressure is not good, even carries out the operation second time.For this reason, people have successfully developed vacuum suction cup on the basis of theory of Chinese medical science, and vacuum suction cup is mainly bled two most of compositions of rifle and vacuum cupping by vacuum cupping, thereby has solved the easy skin ambustion of cupping, the unmanageable deficiency of vacuum magnitude.But in use, the vacuum cupping rifle of bleeding has the following disadvantages: the piston reset vapour lock is big in pumping process, speed slow, the weak effect of bleeding, and brings inconvenience to user; For this reason, many manufacturers and knowledgeable people have carried out the R and D of fruitful ground, but do not have rational product to emerge so far as yet.
Summary of the invention
In order to overcome the existing vacuum cupping above-mentioned disadvantage that rifle exists of bleeding, the purpose of this utility model provide a kind of simple and reasonable, use vacuum cupping light flexibly, that the speed of evacuation is fast, pumping efficiency the is high rifle of bleeding.
The technical scheme that its technical problem that solves this utility model adopts, it comprises handle, handle, pump bowl, piston rod, piston, back-moving spring, handle and piston rod are connected as a single entity, pump bowl is fixedlyed connected with the bottom joint of handle, piston rod and piston are arranged in the pump bowl, back-moving spring is arranged on the piston rod on piston top, described piston is made up of upper piston ring, leather cup, lower piston ring, piston ring is fixed on the piston rod up and down, on the cervical region about leather cup is movably set between the piston ring, be provided with a notch on the centring ring of upper piston ring at least.
Be evenly distributed with two or three notches on the centring ring of described upper piston ring.
Taking out of described pump bowl bottom is provided with the air extraction connector that is connected with vacuum cupping connection tube or vacuum cupping in a fit of anger.
After adopting said structure, this utility model has following advantage and effect: owing on the centring ring of upper piston ring notch is set, when piston reset, gas in the pump bowl of piston bottom is from the gap between the centring ring of leather cup and lower piston ring, via gap between leather cup and the cervical region, to discharge fast through the notch of the centring ring of upper piston ring again, gas circuit is unobstructed, vapour lock is little, piston reset speed is fast, the pumping efficiency height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Shown in Figure 1, be the bleed specific embodiments of rifle of this utility model vacuum cupping, it comprises handle 1, handle 2, pump bowl 3, piston rod 4, piston, back-moving spring 5, handle 2 is connected as a single entity with piston rod 4, pump bowl 3 is fixedlyed connected with the bottom joint of handle 1, piston rod 4 and piston are arranged in the pump bowl 3, back-moving spring 5 is arranged on the piston rod 4 on piston top, described piston is by upper piston ring 6, leather cup 8, lower piston ring 9 is formed, piston ring 6 up and down, 9 are fixed on the piston rod 4, leather cup 8 is movably set in piston ring 6 up and down, on the cervical region between 9, be provided with a notch 7 on the centring ring of upper piston ring 6 at least; Preferably be evenly distributed with taking out of two or three notch 7. described pump bowls 3 bottoms on the centring ring of described upper piston ring 6 and be provided with the air extraction connector 10. that is connected with cup connection tube or cup in a fit of anger
During this utility model work, air extraction connector 10 is connected with vacuum cupping, and vacuum cupping is close to affected part.User is held handle 1, pulling handle 2 drives piston rod 4 behind the elastic force that overcomes back-moving spring 5 and piston moves upward, because leather cup 8 can move relative to the cervical region between the piston ring 6,9 up and down, the bottom surface of leather cup 8 when piston moves upward and the centring ring of lower piston ring 9 be close to sealing, leather cup 8 outer rings are close to pump bowl 3 inwalls again, thereby make pump bowl 3 lower lumen form negative pressure, the distance that handle 2 drive piston rods 4 and piston move upward is long more, and the vacuum that pump bowl 3 lower lumen produce is high more.When user release handle 2, piston rod 4 and piston move downward under the elastic force effect of back-moving spring 5 and reset, because leather cup 8 can be relative to moving on the cervical region between the piston ring 6,9 up and down, in the piston folding process, make between the centring ring of the bottom surface of leather cup 8 and lower piston ring 9 and form the gap, gas in the piston bottom pump bowl 3 is from the gap between the centring ring of leather cup 8 and lower piston ring 9, via gap between leather cup 8 and the cervical region, discharge fast through the notch 7 of the centring ring of upper piston ring 6, the piston reset gas circuit is unobstructed, vapour lock is little, reset speed is fast thereby make again.Carry out above-mentioned action and so forth, then can make to form required negative pressure in the vacuum cupping, tightly inhale at affected part.
