Description

Technical Field

[0001] This invention relates to the field of physiotherapy equipment technology, specifically to a massager based on the principle of vacuum negative pressure for external use by male primates (mainly referring to adult males). Background Technology

[0002] The principle of vacuum negative pressure has been applied to the field of physiological health care and rehabilitation for adult men, and has formed a mature product, usually called a vacuum bucket. This type of device mainly uses a negative pressure cup to generate a controllable negative pressure environment, which causes blood to gather in the external object, thereby achieving temporary size increase and auxiliary health care.

[0003] Currently, mainstream products on the market typically include a negative pressure cup made of rigid materials and a manual or electric air pump system to generate negative pressure. Although its basic physiological mechanism has been verified, there are still several shortcomings in user experience and product design: First, many existing products do not have a dedicated handle on the cup body, requiring users to hold the cup directly, which is not only difficult to apply force and prone to slipping, affecting the stability of negative pressure formation and operational safety, but also makes it impossible to observe the usage status due to the palm obstructing the view; Second, even if some products have a handle, the connection between the handle and the cup body is mostly fixed or structurally simple, and users cannot adjust or replace it according to usage scenarios or personal preferences, limiting the comfort and flexibility of operation; Third, the simplified one-piece design for portability often leads to incomplete cleaning and significant hygiene risks, especially since negative pressure cups have complex structures and are difficult to disassemble and maintain; In addition, the operation buttons (such as the suction and exhaust buttons) are usually fixed in a certain position on the cup body, which may be difficult to reach under different grip postures, affecting the convenience and timeliness of operation. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a vacuum barrel that is suitable for physiological massage and health care for adult men, is easy to operate, has a flexible and diverse handle connection structure, is easy to clean and maintain, and is ergonomic.

[0005] The technical solution of this invention is: Vacuum containers suitable for use outside primates include: A negative pressure cup has a sealable flexible inlet at one end for inserting an external object and transferring negative pressure energy from inside the cup to the external object. The handle is movably connected to the rigid shell of the negative pressure cup, allowing the user to flexibly operate the negative pressure cup.

[0006] Preferably, the negative pressure cup comprises: The rigid cup holder has a handle on its side wall for the user to hold; A rigid cup body, the bottom of which aligns with the rim of a rigid cup base; and The flexible sealing ring has its outer ring fixed to the edge of the mouth of the rigid cup body, and its inner ring forms a channel for external objects.

[0007] Preferably, a handle mounting base is provided between the base of the handle and the side wall of the hard cup holder, so as to facilitate the quick installation of the handle on the hard cup holder.

[0008] Preferably, the inner ring shape and elasticity of the flexible sealing ring adapt to the cylindrical contour of the external object, making it easy to form an airtight space inside the cup.

[0009] Preferably, the rigid cup body comprises: The bottom of the cup has a vacuum system installed on its outer side, which can generate negative pressure to reduce the vacuum level of the airtight space inside the cup on the inner side of the bottom of the cup. The cup is formed by sealing the periphery of its bottom end with the periphery of the cup base. A flexible sealing ring is installed at its mouth end, and the space inside the cup is used to accommodate external objects.

[0010] Preferably, the opening of the rigid cup holder is aligned with the annular periphery of the bottom end of the cup cylinder, thus enclosing the vacuum system within the space of the rigid cup holder.

[0011] Preferably, the operation keys of the vacuum system are located on the front side of the rigid cup holder; or, they are located on the outer side of the grip portion of the handle.

[0012] Preferably, the handle mounting base is a bowl-shaped column; the side wall of the rigid cup holder is provided with a countersunk hole for fixing the handle mounting base.

[0013] Preferably, the outer circular surface of the frustum extending from the base of the handle is axially and circumferentially slidingly fitted relative to the inner circular surface of the bowl-shaped column, which can change the extension direction of the handle relative to the extension direction of the negative pressure cup to adapt to different user needs.

[0014] Preferably, the circumferential limiting groove on the inner circular surface of the bowl-shaped column cooperates with the protrusion on the outer circular end of the frustum to complete the circumferential positioning between the frustum and the bowl-shaped column.

[0015] The beneficial technical effects of the vacuum chamber of the present invention suitable for use outside primates: 1. Significantly improves ease of operation and stability. By setting up a special handle and optimizing its connection with the cup body, it provides users with a stable and effortless grip point, thereby changing the inconvenience of users directly holding the smooth cup body, effectively preventing the risk of slippage during operation, making the vacuuming process more stable and easier to apply force, and greatly improving the safety and controllability of operation.

[0016] 2. It achieves flexibility and versatility in handle connection, conforms to ergonomics, and offers multiple optional modular handle installation solutions, overcoming the limitations of single and non-replaceable handle connection methods. Users can choose different installation modes according to personal habits or usage scenarios, meeting diverse user needs and improving product adaptability and user experience.

[0017] 3. Optimize human-computer interaction and operation experience by flexibly placing the operation buttons of the vacuum system in easily accessible locations such as on the hard cup base or on the outer side of the handle grip, ensuring that users can conveniently, quickly and accurately operate the buttons in any grip posture, thus solving the problem of inconvenient operation.

[0018] 4. Convenience of maintenance: The detachable and separable connection structure (such as the handle being movably connected to the cup body) makes the handle and even the entire vacuum bucket assembly easier to disassemble and reassemble. This facilitates thorough cleaning and disinfection of all parts, especially the inside of the negative pressure cup of the vacuum bucket and the connection points, solving the problem of difficult cleaning in traditional one-piece designs and reducing hygiene risks.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a vacuum barrel suitable for use outside primates, applicable to the physiological health care of male primates, specifically applicable to the physiological health care of adult male external objects, promoting blood to gather in the external object, thereby achieving temporary size increase and erection assistance.

[0024] The vacuum chamber mainly consists of a negative pressure cup 1 and a handle 2. The negative pressure cup 1 has a sealable flexible inlet at one end for inserting an external object and applying the negative pressure generated inside the cup to that object. The handle 2 is movably connected to the rigid shell of the negative pressure cup 1, allowing the user to easily manipulate the cup and increasing the user experience.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the negative pressure cup 1 includes: a rigid cup base 11, a rigid cup body 12, and a flexible sealing ring 13.

[0026] The rigid cup holder 11 has a handle 2 installed on its side wall for the user to hold, which can reduce the negative impact of the weight of the vacuum bucket on external objects.

[0027] A rigid cup body 12 has its bottom abutting the opening of a rigid cup holder 11. Specifically, the rigid cup body 12 includes a cup bottom 121 and a cup cylinder 122. A vacuum system 4 is installed on the outer surface of the cup bottom 121, which can generate negative pressure to reduce the vacuum level of the airtight space inside the cup body on the inner surface of the cup bottom 121. The periphery of the bottom end of the cup cylinder 122 is sealed to the periphery of the cup bottom 121 to form the cup body. A flexible sealing ring 13 is installed at its opening end, and the space inside the cup body is used to accommodate external objects. The cup cylinder 122 is made of transparent material, and its outer surface has graduations along its axial direction to indicate position dimensions. The opening of the rigid cup holder 11 abuts the annular periphery of the bottom end of the cup cylinder 122, covering the space of the rigid cup holder 11 with the vacuum system 4.

[0028] The flexible sealing ring 13 has its outer ring fixed to the edge of the mouth of the rigid cup body 12, and its inner ring forms a channel for the external object. The shape and elasticity of the inner ring of the flexible sealing ring 13 adapt to the cylindrical contour of the external object, making it easy to form an airtight space inside the cup.

[0029] like Figure 3 and Figure 4 As shown, a decorative ring 16 is provided at the connection between the mouth of the rigid cup holder 11 and the bottom of the cup cylinder 122. Preferably, the decorative ring 16 is an electroplated decorative part, which is used to increase the aesthetics of the vacuum barrel.

[0030] like Figure 4 and Figure 6 As shown, the handle 2 includes a gripping part 22 and a truncated cone 21 extending from its root. There are two handles 2, which are symmetrically and movably installed on both sides of the rigid cup base 11 of the negative pressure cup 1, and the gripping part 22 of each handle 2 extends toward the direction of the flexible sealing ring 13 of the negative pressure cup 1.

[0031] like Figure 4 As shown, a handle mounting seat 3 is provided between the base of the grip portion 22 of the handle 2 and the side wall of the hard cup holder 11, so that the handle 2 can be quickly installed on the hard cup holder 11.

[0032] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the handle mounting base 3 is a bowl-shaped column 3a; a countersunk hole 111 for fixing the handle mounting base 3 is provided on the side wall of the rigid cup seat 11. A frustum 21 extends from the base of the handle 2. The outer circular surface 21a of the frustum 21 is axially and circumferentially slidingly fitted relative to the inner circular surface 31 of the bowl-shaped column 3a, allowing the extension direction of the handle 2 to be changed relative to the extension direction of the negative pressure cup 1 to adapt to different user needs. Specifically, the extension direction of the gripping part 22 of the handle 2 is changed relative to the axial extension direction of the negative pressure cup 1 to adapt to different user needs. For example, in this embodiment, the extension direction of the gripping part 22 of the handle 2 is towards the flexible sealing ring 13 of the negative pressure cup 1.

[0033] The bowl-shaped column 3a's rim wall 32 abuts against the root wall 21b of the frustum 21, achieving axial positioning of the handle 2 relative to the negative pressure cup 1. A pair of circumferential limiting grooves 33 are provided on the inner circular surface 31 of the bowl-shaped column 3a. Each circumferential limiting groove 33 engages with a protrusion 21c on the outer circular end of the frustum 21 to achieve circumferential positioning between the frustum 21 and the bowl-shaped column 3a. A pair of axial straight slots 34 are provided on the inner circular surface 31 of the bowl-shaped column 3a. Each axial straight slot 34 communicates with the corresponding circumferential limiting groove 33, together forming an L-shaped sliding groove, creating a channel for different protrusions 21c. The axial straight slots 34 allow the protrusions 21c on the frustum 21 to be inserted along the axial direction of the bowl-shaped column 3a, and then slide along the circumferential limiting groove 33 to the locking position to achieve locking.

[0034] The bottom wall of the circumferential limiting groove 33 of the bowl-shaped column 3a is provided with a locking protrusion 35 extending along the axial direction of the bowl-shaped column 3a; the locking protrusion 35 cooperates with the locking groove 21d extending along the axial direction of the truncated cone 21 on the protrusion 21c of the truncated cone 21 to prevent loosening after the truncated cone 21 and the bowl-shaped column 3a rotate in opposite directions.

[0035] The notch 37 on the periphery of the bottom end 36 of the bowl-shaped column 3a cooperates with the protrusion 113 on the periphery of the bottom end of the countersunk hole 111 on the rigid cup seat 11 to achieve circumferential positioning between the bowl-shaped column 3a and the rigid cup seat 11 of the negative pressure cup 1.

[0036] The bowl-shaped column 3a, through a notch 37 at its bottom end 36, engages with a protrusion 113 within the countersunk hole 111 of the rigid cup holder 11, thus fixing it to the side wall of the cup holder. The frustum 21 at the base of the handle 2 forms a movable connection part by engaging with an L-shaped groove within the bowl-shaped column 3a via a pair of protrusions 21c. The L-shaped groove consists of an axial straight slot 34 and a circumferential limiting groove 33, enabling quick installation and locking of the handle 2. An anti-loosening design is employed, with a locking protrusion 35 on the bottom wall of the circumferential limiting groove 33, which engages with a locking groove 21d on the protrusion 21c to prevent reverse rotation and loosening during use.

[0037] The handle 2 is movably connected to the rigid cup body 12 of the negative pressure cup 1 via the handle mounting base 3. The working principle of its movable connection follows an intuitive push-in, rotation, and locking operation process, as follows: Alignment and insertion: Align the two protrusions 21c on the frustum 21 of handle 2 with a pair of axial straight slots 34 inside the bowl-shaped column 3a and push them in. At this time, the protrusions 21c slide in the axial straight slots 34 until the root wall 21b of the frustum 21 abuts against the bowl-shaped column 3a, completing the axial positioning.

[0038] Rotation and locking: After the protrusion 21c on the frustum 21 reaches the end of the axial straight slot 34, the handle 2 is rotated along the circumferential limiting groove 33. When rotated to the predetermined position (such as the end of the circumferential limiting groove), the locking groove 21d on the protrusion 21c engages with the locking protrusion 35 on the circumferential limiting groove 33, thus completing the locking.

[0039] When adjusting the direction of handle 2, the angle of handle 2 needs to be changed. The user can apply a certain operating force to disengage the locking protrusion 35 from the locking groove 21d, and rotate handle 2 in the opposite direction to drive the protrusion 21c back to the entrance position of the axial straight slot 34. Then, rotate the entire frustum 21 of handle 2 180° to exchange the directions of the two protrusions 21c, realign them with the corresponding axial straight slot 34 on the cup-shaped column 3a, and push them in. The protrusion 21c slides along the axial straight slot 34 until the root wall 21b of the frustum 21 abuts against the bowl wall 32 of the cup-shaped column 3a, achieving axial positioning. Continue to rotate handle 2 along the circumferential limiting groove 33. When the protrusion 21c reaches the locked position, the locking groove 21d on it engages again with the locking protrusion 35 on the circumferential limiting groove 33, thus completing the 180° direction change of handle 2.

[0040] It should be noted that, in addition to the handle 2 being able to be rotated 180°, the handle 2 can also be adjusted to a preset angle according to the user's needs, such as rotating 120°.

[0041] like Figure 1 , Figure 3 and Figure 5As shown, a vacuum system 4 is installed on the outer side of the bottom 121 of the rigid cup body 12, within the internal space of the rigid cup base 11, to generate and control the negative pressure in the sealed space inside the rigid cup body 12. The vacuum system 4 mainly includes an air passage 41, an air valve 42, an operation key 43, an air pump 44, a display panel 45, and a charging interface 46. The vacuum system 4 communicates with the sealed space through the air passage 41 that penetrates the bottom 121. The air valve 42 is located on the air passage 41 and is used to control the opening and closing of the air passage 41. The air inlet of the air pump 44 is connected to the air valve 42, and its outlet is open to the atmosphere, used to draw gas from the sealed space to create negative pressure. The operation key 43 is located on the front side of the rigid cup base 11 of the negative pressure cup 1 and is electrically connected to the air pump 44 to control its start and stop. The charging interface 46 is located at the top of the rigid cup base 11 of the negative pressure cup 1 and is used to charge the vacuum chamber. The display panel 45 is located on the upper front side of the rigid cup seat 11 of the negative pressure cup 1, and is used to display the pressure value in the sealed space in real time.

[0042] It should be noted that the specific arrangement of the vacuum system 4 within the space of the rigid cup base 11 of the negative pressure cup 1 in this invention is not limited to the structure described in the above embodiments. The layout and connection relationship of the air passage 41, air valve 42, operation key 43, air pump 44, display panel 45, and charging interface 46 described in the above embodiments are only a preferred embodiment. Those skilled in the art can, under the inspiration of the concept of this invention, adaptively adjust or reconfigure the relative positions, connection methods, and integration forms of the above components according to actual spatial layout, functional requirements, or production processes. For example, the vacuum system 4 may extend into the inner cavity of the handle 2. These variations and improvements that do not depart from the core design of this invention should all fall within the protection scope of this patent. Example 2

[0043] like Figure 11 As shown, the main difference between the second embodiment and the first embodiment is that the operation key 43 of the vacuum system 4 is located on the outer side of the grip portion 22 of the handle 2 for easy operation. Example 3

[0044] like Figure 12 As shown, the third embodiment differs from the first embodiment in the orientation of the handle 2. Specifically, in the first embodiment, the symmetrically arranged handle 2 has its grip portion 22 extending towards the flexible sealing ring 13 of the negative pressure cup 1; while in the third embodiment, the grip portion 22 of the handle 2 extends away from the flexible sealing ring 13 of the negative pressure cup 1. This change adapts to different gripping habits and force application directions. Example 4

[0045] like Figure 13As shown, the main difference between the fourth embodiment and the first embodiment is that the orientation of the handles 2 on both sides is asymmetrical. Specifically, the grip portion 22 of one handle 2 extends toward the flexible sealing ring 13 of the negative pressure cup 1, while the grip portion 22 of the other handle 2 extends in the opposite direction, which can accommodate different operating gestures and force requirements. Example 5

[0046] like Figure 14 and Figure 15 As shown, the main difference between the fifth embodiment and the first embodiment is that the handle mounting base 3 is an annular sleeve 3b. An annular groove 14 is provided at the annular connection between the rigid cup holder 11 and the rigid cup body 12. The annular groove 14 is formed by making the radial dimension of the connection smaller than the maximum radial dimension of the rigid cup holder 11 and the rigid cup body 12, and is used to fix the annular sleeve 3b.

[0047] The handle 2 has a ring structure, and the outer part of the ring forms the root of the handle 2 and is fixedly connected to the outer wall of the ring sleeve 3b. Example 6

[0048] like Figure 16 As shown, the main difference between the sixth embodiment and the fifth embodiment is that the number of handles 2 is reduced to one. This design provides another simpler structural option to meet different usage preferences. Example 7

[0049] like Figure 17 and Figure 18 As shown, the main difference between the seventh embodiment and the first embodiment is that the handle mounting base 3 uses an elastic open retaining ring 3c. A retaining groove 15 is provided circumferentially at the connection between the rigid cup holder 11 and the rigid cup body 12, and the elastic open retaining ring 3c is engaged in the retaining groove 15 at the connection. The base of the handle 2 is fixedly connected to the outer wall surface of the elastic open retaining ring 3c. Example 8

[0050] like Figure 19 and Figure 20 As shown, the main difference between the eighth embodiment and the first embodiment is that the handle mounting base 3 is an arc-shaped retaining plate 3d. The side wall of the rigid cup holder 11 is provided with an arc-shaped retaining groove 114 adapted to install the arc-shaped retaining plate 3d. The root of the handle 2 is fixedly connected to the outer wall surface of the arc-shaped retaining plate 3d.

[0051] On the inner side of the arc-shaped card plate 3d, there is an insert 38 extending axially along the rigid cup holder 11. Correspondingly, on the side wall of the arc-shaped card slot 114, there is an insertion port (not shown in the figure) extending axially along the rigid cup holder 11. The insert 38 is inserted into the insertion port to achieve positioning and fastening of the arc-shaped card plate 3d within the arc-shaped card slot 114. Example 9

[0052] like Figure 21 a and Figure 21 As shown in b, the main difference between the ninth embodiment and the first embodiment is that the handle mounting base 3 is a hinge 3e. A receiving groove 115 for the handle 2 is provided on the rigid cup holder 11 along its axial direction; the handle 2 is rotatably connected to the rigid cup holder 11 via the hinge 3e. When the handle 2 is in the extended state, the extension direction of the handle 2 is substantially perpendicular to the axial direction of the rigid cup holder 11; when in the retracted state, the gripping portion 22 of the handle 2 is accommodated within the receiving groove 115. Example 10

[0053] like Figure 22 As shown, the main difference between the tenth embodiment and the first embodiment is that the handle 2 is a single structure and is fixedly connected to the rigid cup holder 11. The bottom of the rigid cup body 12 is aligned with the opening of the rigid cup holder 11, thereby achieving a detachable connection between the negative pressure cup 1 body and the handle 2. Example 11

[0054] like Figure 23 As shown, the main difference between the eleventh embodiment and the tenth embodiment is that the operation key 43 of the vacuum system 4 is located on the outer side of the grip portion 22 of the handle 2 for easy operation. Example 12

[0055] like Figure 24 and Figure 25 As shown, the main difference between the twelfth embodiment and the first embodiment is that the extension direction of the grip portion 22 of the handle 2 is parallel to the axis of the negative pressure cup 1.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
