Description

Technical Field

[0001] The present invention belongs to the technical field of massagers, and particularly relates to a manual massager. Background Art

[0002] In the field of male reproductive health diagnosis and treatment, when clinically conducting sperm quality detection, it is necessary to first collect sperm samples. Currently, the standardized collection of sperm samples usually relies on sperm collection massagers. By applying safe and appropriate physical stimulation to the external genitalia, a physiological ejaculation reflex is induced to obtain sperm specimens for detection.

[0003] Existing sperm collection massagers are divided into two types: electric and manual. Among them, the electric collection device, such as a telescopic and torsional massager disclosed in the publication number CN110664603B, although it can achieve multi-dimensional compound movement through motor drive, it relies on an internal power system, has disadvantages such as high battery life requirements, inconvenient charging, and high maintenance costs. Moreover, the complex electromechanical structure is easily affected by a humid environment, resulting in an increase in component failure rates and difficulty in ensuring reliability;

[0004] For the manual operation device, although it has the advantages of portability and cost, its movement form is limited by the characteristics of manual drive, and there are generally technical limitations in the way of realizing functions: problems such as uneven stimulation effects and poor user experience occur in clinical applications.

[0005] Therefore, we propose a manual massager to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems that existing electric massagers are costly and easily damaged, and existing manual massagers have too single a movement mode, and to propose a manual massager.

[0007] To achieve the above purpose, the present invention adopts the following technical scheme:

[0008] A manual massager includes an outer housing. An extension tube is provided at the upper part of the outer housing. An activity unit is disposed through the outer housing. The activity unit includes:

[0009] An inner housing, which is disposed inside the outer housing;

[0010] A screw rod, the lower end of which is fixedly connected to the upper end of the inner housing, the upper end of which passes through the extension tube and extends to the outside, and forms a threaded fit with the extension tube;

[0011] A sleeve, which is sleeved outside the extension tube. The upper end of the screw rod is rotatably connected to the inner top surface of the sleeve.

[0012] Preferably, a return spring is provided between the sleeve and the extension tube. The upper end of the return spring is fixedly connected to the sleeve, and the lower end abuts against the extension tube.

[0013] Preferably, a flexible sleeve is arranged inside the inner shell body. Both ends of the flexible sleeve are provided with openings. The screw rod is of a hollow structure. The lower opening of the screw rod is communicated with the inner opening of the flexible sleeve, and the upper opening of the screw rod is communicated with the outside.

[0014] Preferably, the flexible sleeve is made of silica gel material. A clamping groove is formed on the flexible sleeve, and a clamping ring is arranged on the inner wall of the inner shell body. Through the cooperation of the clamping ring and the clamping groove, the flexible sleeve is detachably connected to the inner shell body.

[0015] Preferably, an adjusting pipe is further included. The adjusting pipe is sleeved outside the extension pipe and is threadedly connected to the lower end of the sleeve.

[0016] Preferably, a shifting tooth is arranged at the lower end of the adjusting pipe.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] As Figures 1-5 shown, a manual massager includes a housing 1. An extension tube 11 is provided at the upper part of the housing 1. Both the housing 1 and the extension tube 11 are cylindrical structures, and the diameter of the extension tube 11 is smaller than that of the housing 1. At the same time, the extension tube 11 and the housing 1 are coaxially arranged. The lower end of the housing 1 is open and turned outwards to increase the contact surface with the human body.

[0028] An activity unit 2 is disposed through the housing 1, and relative movement can occur between the housing 1 and the activity unit 2. The activity unit 2 includes:

[0029] An inner housing 21 is disposed inside the housing 1. The inner housing 21 is also a cylindrical structure, and the outer sidewall of the inner housing 21 is attached to the inner sidewall of the housing 1. The lower end of the inner housing 21 is open. At the same time, in order to improve the user experience, a flexible sleeve 211 is provided inside the inner housing 21.

[0030] A screw rod 22, the lower end of which is fixedly connected to the upper end of the inner housing 21, and the upper end thereof passes through the extension tube 11 and extends to the outside, and forms a threaded fit with the extension tube 11. Threads 12 are provided on the inner wall of the extension tube 11. The screw rod 22 and the threads 12 cooperate with each other to connect the extension tube 11 and the screw rod 22 in a threaded manner. Further, it can be realized that when the extension tube 11 remains stationary, the screw rod 22 can rotate and slide to form a helical motion. When the extension tube 11 can rotate, the screw rod 22 can move along a straight line.

[0031] A sleeve 23 is sleeved outside the extension tube 11. The sleeve 23 is a sleeve structure with an open lower end. The upper end of the screw rod 22 is rotatably connected to the inner top surface of the sleeve 23. Specifically, the sleeve 23 and the screw rod 22 are rotatably connected through a bearing. When the screw rod 22 moves up and down, the lower end of the sleeve 23 can move relative to the upper end of the housing 1.

[0032] Among them, the connection relationship of the core components in this embodiment is as follows: the inner housing 21 and the screw rod 22 are fixedly connected, the screw rod 22 and the extension tube 11 are threadedly connected, the screw rod 22 and the sleeve 23 are rotatably connected, and the sleeve 23 and the extension tube 11 can rotate or slide.

[0033] In this embodiment, the user can place the organ in the flexible sleeve 211 of the inner housing 21. By fixing the outer housing 1 with one hand and pulling the sleeve 23 with the other hand, the inner housing 21 can perform a spiral movement relative to the user's organ to achieve the stimulation effect on the user.

[0034] As a further optimization and improvement, in another embodiment, a return spring 3 is provided between the sleeve 23 and the extension tube 11. The upper end of the return spring 3 is fixedly connected to the sleeve 23, and the lower end abuts against the extension tube 11. A thickened tube is integrally formed inside the lower side of the extension tube 11, and the thread 12 is provided at the thickened tube. The lower end of the return spring 3 abuts against the upper end surface of the thickened tube.

[0035] During use, the user can operate the sleeve 23 with one hand, directly abut the lower end of the outer housing 1 against the body surface, and by pressing the inner housing 21 inward, the inner housing 21 performs a spiral movement and the return spring 3 stores elastic potential energy. When the user releases the hand, the elastic potential energy of the return spring 3 is released, causing the inner housing 21 to reset.

[0036] It should be noted that according to different usage methods of the user, there are the following operation methods:

[0037] When the user releases the hand and does not quickly remove the outer housing 1 but slowly releases the sleeve 23, so that the outer housing 1 still remains in contact with the body surface. At this time, the outer housing 1 is affected by the frictional force with the body and still remains stationary, while the inner housing 21 will reset in a spiral movement.

[0038] When the user releases the hand and quickly removes the outer housing 1, separating the outer housing 1 from the body surface. At this time, the outer housing 1 is no longer affected by the frictional force with the body, enabling the outer housing 1 to rotate, while the inner housing 21 will reset in a linear movement.

[0039] At the same time, the user can also operate with one hand, holding the outer housing 1 with one hand and operating the sleeve 23 with the other hand. When the sleeve 23 resets, by controlling the rotation or fixation of the outer housing 1, the inner housing 21 can perform alternating spiral or linear movements, thereby deriving various operation combination methods.

[0040] That is to say, in this embodiment, according to different operation methods of the user, the inner housing 21 can move in different ways, thus bringing more experiences to the user.

[0041] As a further supplementary solution to the above scheme, in another embodiment, a limiting strip 111 is provided on the outside of the extension tube 11 along its length direction, and a limiting groove corresponding to the limiting strip 111 is opened on the inner wall of the sleeve 23 to limit the sleeve 23 to slide only along the axial direction of the extension tube 11.

[0042] When the user holds and operates the sleeve 23, after the user releases the hand, under the action of the limit strip 111, the outer housing 1 cannot rotate relative to the sleeve 23. At this time, regardless of the speed at which the user releases the hand, the inner housing 21 can only perform a spiral motion. This makes the movement process of the entire inner housing 21 more deterministic.

[0043] That is to say, the user can select and install the sleeve 23 with or without the limit strip 111 according to needs, so as to meet more requirements.

[0044] At the same time, in order to achieve the balance of internal and external air pressure, openings are provided at both ends of the flexible sleeve 211. The screw rod 22 is of a hollow structure. The lower opening of the screw rod 22 is connected to the inner opening of the flexible sleeve 211, and the upper opening of the screw rod 22 is connected to the outside.

[0045] The flexible sleeve 211 is made of silica gel material. A clamping groove is provided on the flexible sleeve 211, and a clamping ring 212 is provided on the inner wall of the inner housing 21. Through the cooperation of the clamping ring 212 and the clamping groove, the flexible sleeve 211 is detachably connected to the inner housing 21, so as to facilitate the disassembly and cleaning of the flexible sleeve.

[0046] Considering individual differences, in another embodiment, an adjustment tube 231 is further included. The adjustment tube 231 is sleeved outside the extension tube 11 and is threadedly connected to the lower end of the sleeve 23. By rotating the adjustment tube 231, the distance from the adjustment tube 231 to the sleeve 23 can be adjusted, so as to adjust the stroke of the inner housing 21. The specific adjustment range is 40 mm - 60 mm.

[0047] In order to facilitate the rotation of the adjustment tube 231, a toothed portion is provided at the lower end of the adjustment tube 231.

[0048] In order to facilitate the observation of the adjustment stroke, a perspective long hole is provided on the side wall of the sleeve 23. The perspective long hole is located at a position corresponding to the adjustment tube 231 and extends along the axis direction of the adjustment tube 231.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
