DETAILED DESCRIPTION OF THE INVENTION

[0026] In order to express the utility model more clearly, the utility model will be further described below in conjunction with attached drawings.

[0027] In the following description, details of generally selected examples are given to provide a deeper understanding of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, but not all of them. It should be understood that the specific embodiments are only used to explain the utility model, but not to limit the utility model.

[0028] It should be understood that when the terms “include” and/or “comprise” are used in this specification, they specify the presence of stated features, integers, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or their combinations.

[0029] The utility model discloses a multi-layer nested inner container easy to disassemble and clean. Refer to FIGS. 1-2, the inner container comprises a soft cup 1, a hard inner long cylinder 2 and an outer cylinder 3; the soft cup 1 is arranged in a cavity of the hard inner long cylinder 2 in an interference fit manner to form a detachable assembly; the soft cup can be well fixed by means of the hard inner long cylinder, and the soft material of the soft cup makes the interference fit structure easy to assemble and stable; the hard inner long cylinder is sleeved with the outer cylinder with a gap between the two; and at least part of an outer surface of the hard inner long cylinder 2 is provided with stoppers 4 which fill the gap between the hard inner cylinder and the outer cylinder, and due to the fact that the stoppers only generate snap-fit and stopping effects locally, the relative contact area is small, so while fixing is realized, the force required for pulling out during disassembly does not have to be very large. The stopper 4 abuts against the outer cylinder to form interference fit, so the stopper can be made of hard materials or malleable materials.

[0030] In this embodiment, a plurality of through holes 21 are formed at intervals on a side wall of the hard inner long cylinder 2, and the stoppers are embedded in the side wall between adjacent through holes. Because the soft cup is made of TPE/TPR/silicone, friction resistance tends to be generated when the soft cup is fit into the hard inner long cylinder, and a sealing structure may be formed so that part of the gas cannot be discharged from the cavity of the hard inner long cylinder, so assembly is very inconvenient. By arranging the through holes in this scheme, the gas can be discharged conveniently, and a user can reach to and hold the soft cup through the through holes to fit the soft cup into the hard inner long cylinder more easily, so that the soft cup can be better attached to an inner surface of the hard inner long cylinder.

[0031] In this embodiment, the stopper 4 is a silicone strip, and the silicone strip partially protrudes from a surface of the hard inner long cylinder. The silicone strip has certain ductility, so as to provide good friction, thus enhancing structural stability.

[0032] In this embodiment, a surface of the stopper facing the outer cylinder is a friction surface.

[0033] In this embodiment, the hard inner long cylinder and the outer cylinder are made of hard plastic.

[0034] A sperm extractor is further provided. Refer to FIGS. 3-4, the sperm extractor comprises the multi-layer nested inner container as described above, and further comprises an outer housing 5 and a control component 6, wherein the inner container is fixed in an inner cavity of the outer housing 5 in a snap fit manner, an opening of the outer housing 5 is in the same direction as an opening of the inner container, the inner cavity of the outer housing also contains the control component 6, and a vibration part of the control component 6 is connected with the soft cup to control the vibration of the soft cup. In this way, the structure of the inner container is better protected, and more functions are realized.

[0035] In this embodiment, the opening of the outer housing 5 is further provided with a guide ring 51 in a snap fit manner, and a protective cover 52 is arranged on the guide ring. The guide ring and the protective cover together form a closed protective structure, which protects the inner environment of the inner container.

[0036] In this embodiment, the control component 6 comprises a battery 61, a circuit board 62 and a vibration motor 63 which are electrically connected, the circuit board 62 and the battery 61 are fixed to the outer housing, and an output end of the vibration motor 63 is connected with a bottom of the soft cup. A button and a charging port of the circuit board are exposed from the outer housing.

[0037] The utility model has the following advantages.

[0038] The soft cup can be well fixed by means of the hard inner long cylinder, and the soft material of the soft cup makes the interference fit structure easy to assemble and stable; the hard inner long cylinder is sleeved with the outer cylinder with a gap between the two; and at least part of an outer surface of the hard inner long cylinder is provided with stoppers, and the stoppers abut against the outer cylinder to form interference fit. Through the stoppers, snap fit is realized, so when the soft cup is pulled out, the hard inner long cylinder can be used as an acting point, which facilitates assembly and cleaning. In addition, the snap fit assembly mode is simple, so assembly efficiency is improved. Further, in the optimized scheme, the hard inner long cylinder is provided with through holes, and a user can reach to and hold the soft cup through the through holes for assembly, so that the assembly process is simple and the structure is more stable.

[0039] Only a few specific embodiments of the utility model are disclosed above, and the utility model is not limited thereto. Any changes that can be thought of by those skilled in the art shall fall within the scope of protection of the utility model.
