Inventive embodiments

Embodiments of the present invention

For a better understanding of the invention, in conjunction with attached drawing, technical solution of the present invention is illustrated by embodiment, explanation When, it same parts and was described in embodiment before being formed in each embodiment, later in embodiment by the default narration, The not missing of technical characteristic, illustrates hereby.

Embodiment one, as shown in Figure 1, which is equipped with the closed housing 1 in front end, 1 front end of housing It is glans penis accommodating space at closing, glans penis overhead is in glans penis accommodating space when use；Flexible inner sleeve is equipped in housing 1 Pipe 2, inner sleeve 2 is roughly the same with 1 direction of housing, and in a ring, 2 front-end and back-end of inner sleeve are open, interior for 2 cross section of inner sleeve 2 point diameter of casing is less than its rear end diameter, and by front end, diameter is gradually increased the present embodiment inner sleeve 2 backward, and whole is in cone cylinder Shape；Inner sleeve 2 is located at glans penis rear portion, and at least point diameter of inner sleeve 2 is less than 1 diameter of housing, its own is leaned in 2 front end of inner sleeve Elastic force lock ring is on the penis at glans penis rear portion, and lock ring position does not have gap between 2 front end of inner sleeve and penis, and back segment gradually loosens To the lock ring degree of penis；2 rear end of inner sleeve is connected with 1 inner wall of housing, and an open front is formed between inner sleeve 2 and housing 1 Body fluid accommodation space 3, body fluid accommodation space 3 refer to the space for accommodating the body fluid that rear portion is flowed to along 1 inner wall of housing.Inner sleeve 2 can It is integrally formed with housing, seperated can also form and be bonded combination again.

When sheath structure is packed, rolled by 1 tail end crimping 6 of housing, until glans penis accommodating space, inner sleeve 2 has Elasticity, with crimping action by rear portion, be partly or entirely involved in wherein, place into packaging bag encapsulation.When 2 part of inner sleeve When being involved in, still there is the front end of inner sleeve 2 not roll, in use, wrapping glans penis, body after glans penis accommodating space is excluded air After glans penis was unfolded, body is slightly lifted, since housing and glans penis all have elasticity, it is easy to even if 2 front end of inner sleeve is fallen into Coronary sulcus loosens body and continues to be expanded to radix penis part, that is, can be used；This coiling method is relatively specific for 2 front end ratio of inner sleeve More forward body.

It when 2 front end of inner sleeve is compared rearward, can all be involved in, setting drawstring 41 on the outside of housing can be attached and rolled up together It rises, 41 front end of drawstring forms one and pulls and supports end 42, and housing can be all involved in by pulling and supporting end 42, and as shown in figure 25, body is in figure Drawstring not yet roll-up state, end 42 is pulled and supported after rolling will be involved in body；Housing, such as Figure 26 can not also be all involved in by pulling and supporting end 42 Shown, body is in drawstring roll-up state in figure, pulls and supports end 42 and is not involved in body；End 42 is pulled and supported to be involved in or non-involvement body, It must meet and pull and support end 42 before inner sleeve 2, drawstring rear end is located at after 2 front end of inner sleeve；Drawstring can be one It can be two or more, can be strip when being one, or tubular, when drawstring is two or more, rear end be can connect Together, it can also be multiple for pulling and supporting end 42；In use, wrapping glans penis, expansion curling after glans penis accommodating space is excluded air Part pulls and supports end 42 to exposing, then pulls back and pulls and supports end 42, drives the body of curling to be unfolded by drawstring, before making inner sleeve 2 End is ploughed under on the inside of housing, and lock ring is on penis, after drawstring is fully deployed, removes drawstring, continues to be unfolded body to radix penis part, It can be used.

It when 2 front end of inner sleeve is compared rearward, can all be involved in, lacing wire can be connected between 2 front end of inner sleeve and housing 1 44, as shown in figure 31, in use, wrapping glans penis, expansion curling body, inner sleeve 2 after glans penis accommodating space is excluded air Front end is under the drive of lacing wire 44 on turning unfolding to penis, and expansion body to radix penis part can be used, body fluid is by between lacing wire Window 45 flows to body fluid accommodation space 3 backward, this structure is simple compared with drawstring formula.

It, can also be on the housing body of housing 1 Yu 2 junction front of inner sleeve when 2 front end of inner sleeve is compared rearward Axial stacking is set, be that turnover type stacks at 46, Figure 33 stacking as shown in Figure 32,33, at Figure 32 stacking is wave stacking 47, as long as concrete mode can make the housing axially extensible shortening opened, nature fold such as also can be used and stack, is spiral Mode makes 2 front end of inner sleeve close to the glans penis accommodating space of 1 front end of housing, and the two can be fitted in one in the case that shape is coincide It rises, is rolled at stacking with housing 1, inner sleeve 2, be put into packaging after rolling.In use, glans penis accommodating space is excluded air After wrap glans penis, body stops expansion after stacked position is unfolded, and lifts body turned up portion undeployed, housing 1 backward Axially expanded at stacking, 2 deploying portion of inner sleeve is moved back by drawing entirety, since 2 front end of inner sleeve and glans penis all have elasticity, It is easy for the coronary sulcus for making 2 front end of inner sleeve fall into glans penis rear portion, then proceedes to expansion body turned up portion to radix penis part, It can be used；The method is succinct compared with drawstring mode.In order to judge stacked position well, can also further stack It is indicated on the outer inner sleeve for putting on or corresponding at stacking at place with the pattern of other colors.

In use, 2 front end lock ring of inner sleeve, on the penis at glans penis rear portion, the body fluid and sperm of wearer's secretion are pulling and pushing In the process, it is caudad flowed along 1 inside of housing, when liquid flows to 2 front end of inner sleeve, since 2 front end lock ring of inner sleeve is in penis On, the lock ring position very close to each other is in high-impedance state to liquid, and position is in low resistive state thereafter, low with outer inner room in inner sleeve Under the guidance for hindering channel, liquid flow posteriorly enclosure space is stored in body fluid accommodation space 3, will not be revealed by housing tail end Out, it prevents wearer's body fluid and sperm from contacting other side, can effectively improve the effect of contraception and the infection of anti-disease.

Meanwhile this structure effectively improves the accommodation space of sperm and body fluid, is not limited in 1 front end of housing, capacity Spatial loop first half spatial distribution in housing has stronger dispersibility, and it is broken in front extruding to be effectively prevented liquid accumulation It splits.

In addition, the position that penis is wrapped up by the housing 1 of inner sleeve 2,2 rear portion of inner sleeve, will not touch the body of wearer Liquid, when use, are not easily susceptible to the lubrication of body fluid and fall off, clean comfortable after taking off.

Since 2 front end of inner sleeve is strapped on penis by elastic force, the binding force is leaned on, is formed between 2 front end of inner sleeve and penis Biggish frictional resistance is influenced by the frictional resistance, when 1 tail end of housing being pulled to take off, drives inner sleeve 2 to turn up, inner sleeve 2 Penis is finally left under frictional resistance delay effect, and inner sleeve 2 turns over the body fluid of the non-sticky both sides in position, outside such housing 1 Other side's body fluid on surface is just not easy to be stained with the glans penis position of wearer, body fluid can be further prevented to intersect；And existing safety Set, not only wearer's body fluid is easy to have with other side's body fluid and intersect in tail end, also can be after other side's body fluid that condom tail end is infected with Glans penis position is arrived in contamination easily when taking off, and this technology can be efficiently reduced or be avoided in these problems.

Elastic binding force by 2 front end of inner sleeve, when wearer extracts out of other side body, the initial stage does not have to hand handle It holds, is also unlikely to whole and falls off in other side's body, but the process that inner sleeve 2 gradually turns up, 2 front end of inner sleeve move on to coronal Ditch, front end, in the case where glans penis edge outstanding stops, obviously add the delay effect of 2 front end of inner sleeve along being embedded in coronary sulcus Greatly, ensured that inner sleeve 2 is finally detached from.

When sexual life, feel to mostly come from glans penis with impulsion, inner sleeve 2 can't cover glans penis, therefore it will not influence Rubbing stimulates to glans penis bring, keeps glans penis to stimulate bring pleasant sensation, but inner sleeve 2 wraps secondary feeling and that gets excited comes The part penis at source glans penis rear portion, housing 1 constitute double-layer structure with it, can isolate decrease friction stimulation, can inhibit penis Pleasant sensation reaches some delay effects, reaches a climax more times to other side.

About inner sleeve tube shape, inner sleeve 2 is to be gradually increased by front end to rear end diameter change in example, and whole is in cone cylinder The other shapes of nonlinear change also can be used in addition to this linear change when implementation in shape, such as curvilinear motion, stepped change, and Be not limited to become larger always with it is diametrically minimum before inner sleeve, inner sleeve leading portion as shown in Figure 2 is in shown in outer gibbosity, Fig. 3 Casing leading portion is in inner concavity, inner sleeve leading portion shown in Fig. 4 is stepped, inner sleeve leading portion shown in Fig. 5 is wave-shaped, shown in Fig. 6 The non-minimum diameter in inner sleeve forward position need to only meet inner sleeve point diameter and be suitable for less than its rear end diameter, inner sleeve front end size The penis at lock ring glans penis rear portion, inner sleeve rear end size are suitable for connecting with housing, it is not limited to this several form；Inner sleeve Two parts can be divided axially into when managing axially longer, back segment is cylinder 201, and leading portion is reducing cylinder 202, as shown in Fig. 2 to 5, this Sample can not only keep forward end seal, but also can reduce back segment to the pressure of penis, also have biggish body fluid accommodation space 3； Diameter, which back and forth changes, can also be such that reducing cylinder 202 is preferably located on penis, hoop it is stronger, sealing is more preferable.

About the relative axial position of inner sleeve 2, it need to only meet 2 front end of inner sleeve when wearing uses and be located at glans penis rear portion On penis, inner sleeve is allowed to have a little fold or accumulation, it is preferable for being located at before penis midpoint with 2 front end of inner sleeve, with It is best that 2 front end of inner sleeve, which is located at coronary sulcus,；2 front end of inner sleeve can be located at coronary sulcus by different dimensional standards when implementation, In use, wrapping glans penis after excluding housing front end air, crimping portion is unfolded, falls in 2 front end of inner sleeve at coronary sulcus, by In user's size difference, if 2 front end of inner sleeve is fallen on glans penis when wearing, since housing and glans penis all have elasticity, set After glans penis was unfolded in body, slightly lifting body rear end can make it fall into coronary sulcus, in order to avoid lifting problem, when design It is contemplated that position is slightly stepped back a bit；It is mutated diminution along to coronary sulcus diameter after glans penis, can effectively anti-reversing be fallen off.

About the axial dimension of inner sleeve 2, body fluid accommodation space 3 of being subject to can meet receiving demand.In coitus, wear Wearer's humoral secretion is process lasting on a small quantity, and the scale of construction is little, and part body fluid can flow into body fluid accommodation space along 1 inner wall of housing 3, the scale of construction for sperm of ejaculating is opposite big, but the stage of ejaculating is in sexual intercourse latter stage, and movement range is obviously reduced, and also there was only part essence Liquid can be pressed into body fluid accommodation space 3, therefore body fluid accommodation space 3 requires lower, and general axial length is greater than 1 centimetre i.e. It can meet the requirements, size that however, it is not limited to this, body fluid accommodation space 3 is a little big, and there are certain redundancies to safety in utilization More preferably, inner sleeve is allowed to have a little accumulation.

Embodiment two, as shown in Fig. 7,8,9, the preventing humor safe cross set, 2 rear end of inner sleeve and 1 tail end of housing are closed Connection, inner sleeve 2 are divided axially into two sections, and back segment is cylinder 201, and leading portion is reducing cylinder 202, and 201 diameter of cylinder is equal to or less than 1 diameter of housing, it is as shown in the figure to be slightly less than 1 diameter of housing, the runner that a section is annular is formed between cylinder 201 and housing 1 8, which extends to the tail end of housing 1, which is also a part of body fluid accommodation space 3, which adds reducing cylinder Space between 202 and housing 1 is body fluid accommodation space 3, which refers to that receiving flows to rear portion along 1 inner wall of housing Body fluid space, Fig. 7 be half unfolded state structural schematic diagram and partial enlarged view.

Fig. 8 show semi-finished product after demoulding, and each section is integrally formed, then cylinder 201 and reducing cylinder 202 are folded to outside Inside set 1, above structure is formed.
