As shown in Figure 3,4, described elastic telescopic gum cover 3 is made using soft rubber material, scalable in a tubular form, set Put outside core cylinder 2 and sleeve 4, its upper end is sealedly and fixedly connected with the lateral wall in edge portion 201, the outside of its lower end and sleeve 4 Wall is sealedly and fixedly connected, and it is used to seal sleeve 4 with the fit clearance of core cylinder 2, but without prejudice to sleeve 4 and core cylinder 2 Axially opposing movement, i.e., when the edge portion 201 of core cylinder 2 is drawn close to sleeve 4, elastic telescopic gum cover 3 is by natural resiliency and sends out The mode of raw fold deformation is shunk, when core cylinder 2 edge portion 201 and sleeve 4 away from when, elastic telescopic gum cover 3 gradually by Stretching.

As shown in Figure 3,4, the present invention is using after above-mentioned design, elastic telescopic gum cover 3 and core cylinder 2 and the common shape of sleeve 4 The Cheng Youyi cavity volume that only lower end communicates with the external world, and under portable suction cup compressive state and extended configuration, the cavity volume Volume size is different, to the cavity volume lower end closed after, when volume changes from small to big, internal pressure certainly will diminish and produce negative Pressure, technical requirements needed for so as to can reach cup.

The operation principle of this portable suction cup is：

First, this portable suction cup is adjusted to into compressive state, i.e., as shown in Fig. 3,5, by external device (ED) or operation The body gravity of person, the edge portion 201 for ordering about core cylinder 2 is drawn close to sleeve 4, and four high pressure springs 5 are compressed in spring base 402 And energy accumulating state is reached, when edge portion 201 and the upper end of sleeve 4 are supported, locking mechanism is by the relative position of core cylinder 2 and sleeve 4 Putting carries out provisional locking, now due to the fully-inserted sleeve 4 of core cylinder 2 among so that the most air quilts in sleeve 4 Discharge；Then, the body surface for treating cup position is cleaned process, and this portable suction cup is placed on into cup position, and really Protect the bottom of sleeve 4 to be in close contact with body surface；Finally, this device is reverted to into extended configuration, i.e., as shown in Fig. 4,6, by unblock Mechanism come the mechanism that unlocks to the locking between sleeve 4 and core cylinder 2, under the powerful thrust produced by four high pressure springs 5, Core cylinder 2 is moved up by thrust, and the cavity volume lower end that now core cylinder 2, sleeve 4 and elastic telescopic gum cover 3 are collectively forming is by suffering from Person's body surface is closed and is hedged off from the outer world, and the upper shifting of core cylinder 2 makes the cavity volume become big, so as to produce negative pressure, after staying tank for a period of time, i.e., Realize the purpose of negative-pressure cupping；Finally, manual unlocking breather valve 1 before tank is played, outside air is entered in negative pressure cavity volume, so as to This portable suction cup easily can be removed from patient body.

As shown in Fig. 1,3,5, in the structure of this portable suction cup, because it is without appurtenances such as piston, piston rods, Sleeve 4 and core cylinder 2 can be caused to design using short cartridge type so as to overall structure more compact；And in compressive state high pressure Spring 5 can be accommodated among the spring base 402 of guiding rib 401 so that the edge portion of core cylinder 2 201 can support with sleeve 4, so as to So that this portable suction cup is very frivolous under compression, its portability is increased.

As shown in Fig. 4,8,9, in the structure that sleeve 4 is adopted, the one side of guiding rib 401 is acted on guide-localization, On the other hand the effect of storage high pressure spring 5 is then served, so that the side wall of sleeve 4 can adopt lightening design；Further For, the upper end of guiding rib 401 is concordant with the upper end of sleeve 4, but the lower end of guiding rib 401 keeps spacing with the lower end of sleeve 4, thus Guarantee the ring surface that the lower surface of sleeve 4 is standard, it is tighter during so as to being conducive to being fitted with patient body-surface.

In the structure of above-mentioned portable suction cup, need to ensure that sleeve 4 and core cylinder 2 can occur axially opposing movement but all the time Without departing from realizing that the technical purpose can adopt multiple means；Due to core cylinder 2 along sleeve 4 move down when, the edge of its upper end Portion 201 can play position-limiting action, therefore only set up another position limiting structure on core cylinder 2 or sleeve 4 to prevent core cylinder 2 from moving upwards Slip from sleeve 4 when dynamic, and this position limiting structure is common, known in sliding pair.

At the same time, realize sleeve 4 and core cylinder 2 can occur axially opposing movement but all the time without departing from, may also be employed as Under means：As shown in Figure 3,4, the elasticity of described elastic telescopic gum cover 3 and length need to ensure：When high pressure spring 5 stretches, Elastic telescopic gum cover 3 is that sleeve 4 provides a traction force with core cylinder 2, prevents both from departing from.

In above-mentioned portable suction cup, the effect of locking mechanism and unlocking mechanism is that locking mechanism is used for core Cylinder 2 is locked with the relative of sleeve 4 for position, and the purpose of unlocking mechanism is can be released aforesaid locking, with Just core cylinder 2 can occur relative movement with sleeve 4, and based on above-mentioned purpose, locking mechanism has various common realities with unlocking mechanism Apply mode.Such as, as shown in Fig. 5,6,7, the pellet seat 206 of a blind hole shape, pellet are respectively provided with the bottom both sides of cylinder 202 It is installed on extrapolation spring 8 and positioning pellet 7 in seat 206 from inside to outside；The both sides of sleeve 4 are respectively provided with one and pierce determining for its side wall Position hole 403, is provided with slidable top bolt 6 in location hole 403；When edge portion 201 and 4 upper-end contact of sleeve, two positioning pellets 7 One part is set to penetrate in the corresponding location hole 403 of sleeve 4 by extrapolation spring pushing and withstanding, so as to by core cylinder 2 and the relative position of sleeve 4 Put and locked, and while push up bolt 6 be subject to positioning pellet 7 thrust and be displaced outwardly, its outer end finally with the lateral wall of sleeve 4 It is concordant or be higher by the lateral wall of sleeve 4；When two top 6 outer ends of bolt is pressed inward against manually, two positioning pellets 7 can be ordered about and be reset to pellet In seat 206, so as to solve the locking for decoring cylinder 2 and the relative position of sleeve 4.

As shown in Figure 5,6, when the locking mechanism and unlocking mechanism of portable suction cup adopt aforementioned structure, described bullet Property flexible gum cover 3 lower end should be positioned at the downside of location hole 403 with the position that is fixedly connected of sleeve 4；Thus can easily avoid The side wall of sleeve 4 due to location hole 403 presence and it cannot be guaranteed that air-tightness.

Because the purposes of two top bolts 6 is that, used as a kind of load transfer device, the force of operator is passed to positioning pellet 7 by it And promote the positioning movement realization of pellet 7 to unlock, by theory for, when positioning pellet 7 and being in positioning states, push up bolt 6 The more outside protrusion in outer end is more easily unlocked operation, but pushes up more, the one side shadow that such as protrudes from the side wall of sleeve 4 of bolt 6 The overall appearance of portable suction cup is rung, on the other hand is also unfavorable for implementing close to location hole 403 using elastic telescopic gum cover 3 Envelope.To overcome the problems referred to above, in the present invention, as shown in Fig. 7,12, the outer end of described location hole 403 is provided with tapered pit 404, when operator is with finger extruding top 6 outer end of bolt, moves inward can top bolt 6 and obtain bigger displacement, thus may be used Guarantee that push up bolt 6 realizes unlocking by the positioning pushing and withstanding of pellet 7 into pellet seat 206.After using above-mentioned improvement, when positioning pellet 7 when being in the lock state, the top outer end of bolt 6 without the need for the excessive lateral wall for protruding from sleeve 4, so as to ensure that portable suction cup Overall appearance, while being also beneficial to implement location hole 403 effectively sealing by elastic telescopic gum cover 3.

As shown in Fig. 4,6, in above-mentioned portable suction cup, elastic telescopic gum cover 3 is more prone to using straight-tube shape structure Make and be attached with other associated members, therefore described elastic telescopic gum cover 3 adopts straight tube structure, and the edge of core cylinder 2 Portion 201 is equal with the external diameter of sleeve 4, so as to be conducive to being stably connected with elastic telescopic gum cover 3；At the same time, due to core The edge portion 201 of cylinder 2 is equal with the external diameter of sleeve 4 so that entirely portable suction cup external structure more neatly with it is attractive in appearance.

It is to improve high pressure spring 5 therewith because the lower surface in the edge portion 201 of core cylinder 2 need to be supported with four high pressure springs 5 The stability of cooperation, the lower surface in described edge portion 201 is provided with four to be used to respectively carry out the upper end position of high pressure spring 5 The connected structure of restriction, as shown in Fig. 4,9, the connected structure is the convergence hole 205 for accommodating the upper end of high pressure spring 5；Also can be such as figure Shown in 13, the connected structure is to insert the engaging column 207 in the upper end of high pressure spring 5.

In this portable suction cup, the purposes of breather valve 1 is：Breather valve 1 is in cut-off state during cup, Outside air cannot be introduced in the negative pressure space in portable suction cup, breather valve 1 be adjusted to connected state when playing tank, make outer Boundary's air is entered in negative pressure cavity, thus makes the negative pressure needed for cup disappear, and whole portable suction cup just can easily from patient Remove with it, thus for, common manually-operated gate is capable of achieving the technical purpose.

But in the present invention, it is contemplated that another problem, because high pressure spring 5 has larger elastic force, and portable cup Device has preferable air-tightness again, will certainly produce larger negative pressure in cup, and it is that negative pressure is moderate that Chinese medicine cup is particular about, Not it is the bigger the better, such as during cup, negative pressure is excessive, larger injury can be caused to the body part of cup, therefore, It is very necessary to set up on portable suction cup to the relief valve that vacuum magnitude is controlled, but individually set up one it is adjustable The relief valve of control vacuum magnitude will certainly cause whole device complex structure, also be unfavorable for cost control.For this purpose, the present invention is right Vent valve structure has carried out scientific design so as to had negative pressure adjusted and controlled function concurrently.Specific embodiment is, as shown in Figure 10,11, Described breather valve 1 includes the valve pocket 111 of a bottom for being vertically installed in core cylinder 2, and the valve pocket of cylindricality is provided with inside valve pocket 111 108, the lower end of valve pocket 108 is provided with the air inlet 110 of the bottom 203 for piercing core cylinder 2, and the described upper end of valve pocket 111 is provided with once spiral shell Stricture of vagina seals against the bonnet 102 of combination, and the middle part of bonnet 102 is provided with passage 104, is pasted with ring on the lower surface of bonnet 102 First sealing gasket 103 of shape；An axially slidable plug 107, the lower section peace of the plug 107 are provided with described valve pocket 108 Pushing top spring 109 is provided with, the top of plug 107 is installed on depression bar 105, and the described upper end of depression bar 105 passes through the ventilation of bonnet 102 It is fixedly connected with a pressure handle 106 behind hole 104；The second sealing gasket in a ring is pasted with the upper surface of described plug 107 101；The first sealing gasket 103 is fitted with the second sealing gasket 101 and makes breather valve 1 be in cut-off state under naturalness；When first When the sealing gasket 101 of sealing gasket 103 and second has gap, breather valve 1 is in connected state, and outside air is through passage 104 The gap in gap, valve pocket 108 and plug 107 with depression bar 105, air inlet 110 are entered in the negative pressure cavity of portable suction cup.

Described breather valve 1, in cup, is pacified using after structure shown in Figure 11 when portable suction cup internal negative pressure is less than During total head, plug 107 orders about the second sealing gasket 101 in the presence of pushing top spring 109 and is brought into close contact with the first sealing gasket 103, Breather valve 1 is in cut-off state；When playing tank, pressing pressure handle 106 makes the second sealing gasket 101 separate with the first sealing gasket 103, ventilation Valve 1 is in connected state, and outside air Jing it enters in the negative pressure space of portable suction cup；The negative pressure produced when cup is big When safety value, the thrust that extraneous atmospheric pressure applies to plug 107 is close so as to order about second more than the thrust for pushing up spring 109 Packing 101 is moved down makes it separate with the first sealing gasket 103, and breather valve 1 is opened, outside air Jing its enter portable cup In the negative pressure space of device, when portable suction cup internal negative pressure weakens to safety value, pushing top spring 109 will order about the second sealing Pad 101 to the first sealing gasket 103 is moved, and finally ends breather valve 1, makes portable suction cup internal negative pressure maintain safety value On.Because bonnet 102 is threaded connection with valve pocket 111, i.e. the upper-lower position of bonnet 102 can be regulation, so as to pass through The upper-lower position of regulating valve bonnet 102 is come the purpose realizing setting safety value size.

In cupping therapy, due to making the rapid congested, congestion of body local, little blood capillary even break in negative pressure in tank Split, hematoclasis, haemolysises occur.The release of hemoglobin in erythrocyte is a kind of optimal stimulation to body, can be passed through Nervous system carries out two-ways regulation to the function of histoorgan, while promoting the phagocytosiss of leukocyte, improves skin to external world The sensitivity and tolerance of change, so as to the immunity of enhancing body.Existing cupping device to the stimulation of human body only with The negative pressure produced in tank, stimulates more single, and its congestion speckle for being formed often is limited only to the regional area at cup position, effect Fruit still has much room for improvement；At the same time, the structure of this portable suction cup tends to frivolous compact design, for producing the chamber of negative pressure Room is shallower, and such as in addition skin more relaxes patient's fat strand larynx, it is easy in the entrance sleeve excessive by vacuum suction so that Negative pressure is not enough and do not have expected cup effect.

For this purpose, in this portable suction cup, as shown in Figure 12,13, a grading shield 9 is placed with inside the lower end of sleeve 4, The grading shield 9 is made up of ring for fixing 902 and roundness mess cloth 901, outer rim and the ring for fixing 902 of described roundness mess cloth 901 It is fixedly connected, the inwall of sleeve 4 is close in the described lateral wall of ring for fixing 902, ring for fixing 902 is limited by the lower end of guiding rib 401 And without the movement of the top of normal direction sleeve 4.After using above-mentioned design, in cup, negative pressure provides a pull strength upwards to skin, And grading shield 9 provides skin a pressing force, it is to avoid skin excessive deformation, vacuum suction is thus served with physical depression Double stimuli, and it is more balanced to be conducive to negative pressure suffered by cup position to stimulate.In addition, roundness mess cloth 901 can also Jing medicines in advance Immersion is steeped, and thus by cup in combination with treatment by Chinese herbs, therapeutic effect is more preferably.
