Description

Technical Field

[0001] The present invention relates to the technical field of massage devices, and in particular to a reciprocating massage device. Background Art

[0002] Reciprocating massage devices (also known as massage devices) are designed to produce a range of different motions, such as vibration, rotation, thrust and compression. The thrust and compression motions can be produced by a reciprocating motion action, where one element can move forward and backward in a line. Since such devices generally use an electric motor that can produce rotational motion, the reciprocating motion can be produced by mechanical elements such as cams (i.e., crank-connecting rod reciprocating mechanisms) that convert the rotational motion of the motor into reciprocating motion, or by mounting a push rod on a rotating disk or wheel that drives the push rod to push and pull in a roughly reciprocating direction.

[0003] However, such existing methods of providing reciprocating motion suffer from inefficient power utilization, requiring awkward device shapes to accommodate the required mechanical elements, limited stroke lengths, weak drive forces for portable arrangements, and asymmetric forces for ascending and descending strokes. Summary of the invention

[0004] The present invention aims to solve the technical problems existing in the above-mentioned prior art and provide a reciprocating massage device which has high transmission efficiency and occupies little space.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A reciprocating massage device described in the present invention comprises a handle portion and a massage body arranged on the handle portion, wherein a nut assembly and a screw rod which cooperates with the nut assembly and can rotate are arranged in the handle portion, and the screw rod is rotated to make the screw rod reciprocate relative to the nut assembly, thereby driving the massage body to reciprocate relative to the handle portion.

[0007] The reciprocating massage device described in the present invention realizes the reciprocating motion of the rotating screw along its own length direction through the cooperation of the screw and the nut assembly, and drives the massage body to reciprocate through the reciprocating motion of the screw, so as to realize the reciprocating stimulation of the massage body to the contact part with the human body. Compared with the crank connecting rod reciprocating mechanism in the prior art, the cooperation of the nut assembly and the screw in the present invention can greatly reduce the space occupied and has high transmission efficiency. In addition, the screw can be lifted and lowered in its length direction directly through the cooperation of the screw and the nut assembly, which can effectively avoid the problem of asymmetric ascending and descending stroke forces of the crank connecting rod reciprocating mechanism.

[0008] Furthermore, a stirring shaft is provided on the screw rod, and the stirring shaft is configured to drive the head of the massage body to swing during the rotation of the screw rod.

[0009] Furthermore, a massage component is connected to the free end of the stirring shaft, and the stirring shaft causes the massage component to swing when rotating, thereby driving the head of the massage body to swing.

[0010] Furthermore, the stirring shaft includes a first section of the rod body connected to the screw and a second section of the rod body connected to the first section of the rod body, and the first section of the rod body and the second section of the rod body are arranged at an angle.

[0011] Furthermore, the external thread on the screw is a double helical groove, and a portion of the nut assembly is located in the double helical groove. When the screw rotates, the nut assembly can continuously move in the double helical groove to cause the screw to rise and fall.

[0012] Furthermore, the double helical groove includes an ascending groove that drives the nut assembly to rise and a descending groove that drives the nut assembly to descend, the ascending groove and the descending groove are staggered with each other, and the top of the ascending groove is connected to the top of the descending groove, and the bottom of the ascending groove is connected to the bottom of the descending groove.

[0014] Furthermore, the reciprocating massage device also includes a torque receiving structure, which is driven to rotate by the rotary drive mechanism, and the torque receiving structure allows the screw to move freely up and down during rotation.

[0015] Furthermore, the reciprocating massage device also includes an outer sleeve, which surrounds the outer sleeve and rises and falls with the screw; a detection device for detecting the lifting stroke displacement of the outer sleeve is arranged between the outer sleeve and the inner sleeve.

[0016] Furthermore, the reciprocating massage device also includes a stretchable tube, which connects the outside of the handle part and the outside of the massage body.

[0029] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the relevant drawings.

[0030] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to another element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] Exemplary embodiments of the present invention provide a reciprocating massage device (i.e., a reciprocating massage device) that utilizes various screw, nut, or guide pin arrangements to generate a reciprocating motion from the unidirectional rotational motion of an electric motor, thereby providing the desired stimulation vectors in a compact and portable form factor while efficiently utilizing battery power.

[0033] For example, the reciprocating massage device (also known as a reciprocating massage device) may include a base assembly and a top assembly, and a stretchable tube connecting the base assembly and the top assembly. A screw can be driven by a rotary motor in the base assembly or a drive mechanism that outputs a rotary motion such as a motor. The screw can extend upward into the top assembly, but the screw is not directly connected to the top assembly. The top assembly may include a nut or guide pin fixedly connected to the base assembly, and the nut or guide pin can engage with the screw. Therefore, when the drive mechanism rotates the screw, the top assembly can be driven upward and / or downward by virtue of the cooperation of the nut / guide pin and the screw, and the stretchable tube can ensure that the top assembly remains connected to the base assembly. In this way, a reciprocating motion can be established.

[0034] The top component may include a stimulating shape on the outside, which is mainly used to be inserted into the female vagina or the male anus, and the reciprocating stimulation of the top component can sexually stimulate the aforementioned specific parts of the human body, so that the user can have a pleasant experience. It can be seen that the user of the reciprocating massage device can receive stimulation and produce a pleasant feeling through the reciprocating movement of the top component relative to the base component. The base component may include a mounting means so that it can be detachably mounted on a fixed object.

[0035] The directionality of the reciprocating motion can be alternated between expansion and contraction by one of several different means. For example, the rotation of the drive mechanism can be reversed to alternate the directionality of the reciprocating motion. Alternatively, the screw can be threadedly connected to a nut or guide pin with a double helical groove (including an ascending groove and a descending groove), the ascending groove being the groove responsible for driving the top assembly away from the base assembly, and the descending groove being the groove responsible for driving the top assembly toward the base assembly, so that the nut or guide pin will be set in the ascending groove of the screw and cooperate with the ascending groove of the screw to drive the top assembly away from the base assembly until the nut or guide pin reaches the top of the screw, at which time it enters the descending groove, and the nut or guide pin cooperates with the descending groove of the screw to drive the top assembly to move in the direction of the base assembly. When the nut or guide pin reaches the bottom of the screw, it enters the ascending groove again from the descending groove, and the top assembly is pushed up again. Through the cooperation of the nut or guide pin and the screw, when the nut or guide pin is driven by the double helical groove of the screw, the top assembly will exhibit reciprocating motion.

[0036] Various other components may be included to facilitate reciprocating motion or to add stimulation functionality to the device. Many of these components and their operation will be described in detail below. However, it should be understood that any combination of these various other components may be used with the basic operating method discussed above.

[0037] In the various figures, many of the same elements are shown in multiple figures but are not described again for each figure in which they appear. Therefore, it can be assumed that if an element is not described in one figure, it is at least similar to the corresponding element shown and described in another figure. Like reference numerals may represent similar elements throughout the specification and figures.

[0038] Figure 1 is a cross-sectional view of a reciprocating massage device 100 according to an exemplary embodiment of the present invention. The figure shows that the base assembly includes a removable housing 117 that engages with a fixed housing 119, for example, by screws. The removable housing 117 can be removed to expose the battery 110, the rotary motor 107 and various other components. The reciprocating massage device 100 may also include a charging port 120, a first button 111A and a second button 111B, and a printed circuit board (PCB) 118. See Fig.10 A first support structure 152 supporting the printed circuit board 118 is provided on the inner wall of the removable housing 117 and the inner wall of the fixed housing 119, and a support side plate 153 is provided on the side of the first support structure, wherein the top and bottom ends of the support side plate of the fixed housing 119 (the top and bottom ends are relative to each other) are Fig.10 In terms of the state in the embodiment, clamping grooves 154 are respectively provided opposite to each other, one side of the printed circuit board 118 abuts against the first supporting structure in the removable housing 117, and the other side abuts against the first supporting structure in the fixed housing 119. The top of the printed circuit board 118 is clamped in the clamping groove at the top of the supporting side plate in the fixed housing 119, and the bottom of the printed circuit board 118 is clamped in the clamping groove at the bottom of the supporting side plate in the fixed housing 119, so that the printed circuit board 118 is firmly installed in the housing formed by the fixed housing 119 and the removable housing 117. In addition, see Fig.10 A second supporting structure 155 for supporting the motor or the rotary motor is provided on the inner wall of the fixed shell 119 and the inner wall of the removable shell 117. An arc-shaped recess is provided on the second supporting structure to adapt to the contour of the motor or the rotary motor. The motor or the rotary motor is firmly clamped inside the shell formed by the fixed shell 119 and the removable shell 117 through the second supporting structure in the fixed shell 119 and the second supporting structure in the removable shell 117.

[0039] See also Figure 1, a wire trough 114 may be included behind the removable housing 117 as a protective passage for wires and / or other conductive elements extending from the rotating motor 107 to the printed circuit board 118. These wires and / or other conductive elements may also pass through an opening 115 arranged behind the removable housing 117.

[0040] See also Figure 1 The massaging body 102 (not shown) may contain a bearing component 103 and a massaging component 101 .

[0041] Figure 2 is a cross-sectional view of a reciprocating massage device 100A according to an exemplary embodiment of the present invention, Figure 7 The cross-sectional view of the reciprocating massage device according to the exemplary embodiment of the present invention is shown in FIG. Figure 8 yes Figure 7 It should be assumed that where one or more elements of the device are not described in detail with respect to the figure, these elements may be at least similar to corresponding elements described elsewhere in the present disclosure. Figure 2-6 as well as Figure 7 and Figure 8 , comprising a handle portion 108 and a massage body 102 disposed on the handle portion 108, wherein the handle portion 108 and the massage body 102 are assembled together to form a whole having a cavity inside, wherein a detachable housing 117 and a fixed housing 119 are disposed in the handle portion 108; a screw 124 and a nut assembly matched with an external thread of the screw 124 are disposed in the cavity; the screw 124 is connected to the massage body 102 through a massage component 101, and the nut assembly is coupled to the handle portion 108, and the screw 124 is configured to drive the reciprocating motion of the massage body 102, and when the screw 124 rotates, the massage body 102 is driven to reciprocate relative to the handle portion 108; The screw 124 cooperates with the nut assembly to realize the reciprocating motion of the rotating screw 124 along its own length direction. The reciprocating motion of the screw 124 drives the massage body 102 to reciprocate, thereby realizing reciprocating stimulation of organs such as the vagina or the anus through the massage body 102. Compared with the crank-connecting rod reciprocating mechanism in the prior art, the nut assembly and the screw 124 cooperate in the present invention, which can greatly reduce the space occupied and has high transmission efficiency. In addition, the screw 124 is directly lifted and lowered in the length direction through the cooperation of the screw 124 and the nut assembly, which can effectively avoid the problem of asymmetric ascending and descending stroke forces of the crank-connecting rod reciprocating mechanism.

[0042] Here, in Figure 2 In this embodiment and in Figure 7In this embodiment, the screw 124 may have the same double helical groove arrangement as described above, and the nut assembly is partially located in the double helical groove, and when the screw 124 rotates, the nut assembly continuously moves in the double helical groove 131, causing the screw 124 to rise and fall, wherein the double helical groove 131 includes an ascending groove that drives the nut assembly to rise and a descending groove that drives the nut assembly to descend, wherein the ascending groove and the descending groove have different rotation directions, which can be understood as one is left-handed and the other is right-handed, and the two are interlaced with each other, and the top of the ascending groove is connected to the top of the descending groove, and the bottom of the ascending groove is connected to the bottom of the descending groove, so that the nut assembly can enter the descending groove from the ascending groove, or enter the ascending groove from the descending groove, ensuring that the screw 124 can effectively achieve reciprocating motion when it rotates in one direction. In addition, this arrangement also includes a battery / power supply 110, a rotary motor 107 and a controller 109 disposed in the handle portion 108, but here, the nut assembly is fixed in the handle portion 108 because the nut assembly is fixed inside the handle portion 108 by using a fixing ring or an upper cover. The torque receiving structure can be used to couple the rotary motor 107 with the screw 124 so that the screw 124 is rotated by the rotation of the motor 107. However, here, since the nut assembly is stationary relative to the handle portion 108, when the screw 124 is rotated, the screw 124 reciprocates relative to the stationary nut assembly. Therefore, the torque receiving structure 150 is configured to transmit the rotational force to the screw 124, while the screw 124 remains free to move up and down.

[0043] A conductive subassembly 104 transfers power from the battery / power source 110 to a conductive subassembly 143 and from there to the massage element 101. A stretchable tube 106 again connects the exterior of the handle portion 108 to the exterior of the massage body 102. Figure 2 In this embodiment, the screw 124 is matched with a ball bearing 142, which is matched with the bearing member 103, so that the screw 124 can push and pull the bearing member 103 up and down, and the bearing member 103 does not have to rotate with the rotation of the screw 124. In this way, the reciprocating motion of the screw 124 can be transmitted to the bearing member 103, and the rotational motion of the screw 124 will not affect the bearing member 103. In addition, see Figure 7 and 8The reciprocating massage device also includes a stretchable tube 106, which connects the outside of the handle portion 108 and the outside of the massage body 102. It can be understood that the stretchable tube 106 is a soft sleeve, for example, made of silicone material. The soft sleeve is wrapped around the massage body 102 (i.e., the top component) and the handle portion 108 (i.e., the base component) to wrap the massage body 102 and the handle portion 108 and connect the two. Since the stretchable tube 106 is made of soft material, it can cooperate with the reciprocating massage device to achieve the functions of telescopic stimulation and stirring stimulation. At the same time, the soft material will not damage the skin of the user's vagina or anus, ensuring safe use. In addition, the handle portion 108 and the massage body 102 are sealed and wrapped as a whole by the soft material, which also prevents body fluids from entering the reciprocating massage device and contaminating or damaging the reciprocating massage device.

[0044] again, Figure 2 In this embodiment, the bearing member 103 cooperates with the massage body 102 to make the massage body 102 present a reciprocating motion. Figure 7 and 8 , the stirring shaft cooperates with the massage body 102, so that the massage body 102 simultaneously presents a reciprocating motion and a swinging state, that is: a stirring shaft is arranged on the screw 124, one end of which is connected to the screw 124, and the other end is abutted against the head of the massage body 102 through a vibration motor, wherein the vibration motor is the massage component 101, and the stirring shaft is configured to drive the head of the massage body 102 to swing during the rotation of the screw 124. When the massage body 102 is inserted into the vagina or anus of the user, as the stirring shaft rotates, the muscles of the vagina or anus of the user can be stirred and stimulated by the head of the massage body 102. It can also be understood that the massage body 102 changes the massage of the vagina or anus of the user in real time as the stirring shaft rotates. The invention provides a massage stimulation at different positions; a massage component 101 is connected to the free end of the stirring shaft, and the stirring shaft causes the massage component 101 to swing when rotating, so as to drive the head of the massage body 102 to swing, and the stirring shaft includes a first section rod body 1031 connected to the screw 124 and a second section rod body 1032 connected to the first section rod body 1031, and the first section rod body 1031 and the second section rod body 1032 are arranged at an angle, and the angle range is 90°<α<180°, preferably 110°≤α≤170°. Through the special structure of the stirring shaft, the stirring shaft can drive the massage component 101 to rotate and swing at the same time as the screw 124 rotates, thereby stimulating different positions of the vagina, that is, stirring stimulation. Figure 7The embodiment of the reciprocating massage device in the embodiment can achieve both telescopic stimulation and stirring stimulation. Through the combination of the two, different positions of the user's vagina or anus can be stimulated, and the intensity of the stimulation is further improved, and the user has a stronger sense of pleasure and a better experience; in addition, the length of the first section of the rod 1031 is longer than the length of the second section of the rod 1032, and the length ratio of the two is 10:1, that is, when the length of the first section of the rod 1031 is 10 cm, the length of the second section of the rod 1032 is 1 cm. Through the combination of the angle and length of the first section of the rod 1031 and the second section of the rod 1032, it can be ensured that the second section of the rod 1032 after being bent will not cause the head of the massage body 102 to extend too much in the lateral direction after being connected to the massage component 101, thereby affecting the user experience and the aesthetic appearance of the product.

[0045] Figure 3 yes Figure 2 100A. Here, the rotary motor 107 rotates the torque receiving structure 150, which in turn transmits the rotational force to the screw 124. A cylindrical body 149 having a hollow interior can be fixed by an annular base 151, and these components can be fixed together relative to the handle portion. A pair of conductive scrapers 147A and 147B can cooperate with the cylindrical body 149 and can carry power from a battery. Each conductive scraper 147A and 147B includes an arc-shaped contact 146 at its upper end. The arc contacts 146 establish electrical connections with the corresponding conductive strips 135A and 135B, which are part of the reciprocating structure, so that when the conductive strips 135A and 135B exhibit reciprocating motion, the arc contacts 146 of the conductive scrapers 147A and 147B scrape along the conductive strips 135A and 135B, thereby maintaining electrical connection and delivering power to the device 100A and the massage part 101. The conductive scrapers 147A and 147B and the conductive strips 135A and 135B can each be formed by a graphite brush (e.g., a carbon brush).

[0046] Figure 2 In this embodiment, the nut assembly includes a cylinder 149, brackets 128A and 128B, a guide pin 132, and an upper cover 129 / fixing ring 145 for fixing the guide pin 132 on the cylinder 149, and an annular base 151 for fixing the cylinder 149 on the handle portion 108, so that the nut assembly does not move relative to the handle portion 108. Of course, the nut assembly may also be fixed without brackets 128A and 128B, see Figure 7 and 8In this embodiment, the nut assembly includes an inner sleeve 136, a guide pin 132, an upper cover 129, and an annular base 151. The inner sleeve 136 is connected to the annular base 151 through a fastener, and the annular base 151 is coupled to the handle portion 108, so that the nut assembly cannot move relative to the handle portion 108. Grooves are respectively provided at the top of the inner sleeve 136 and the bottom surface of the upper cover 129. When the upper cover 129 is covered on the top of the inner sleeve 136, the grooves of the two are connected to form a clamping hole 173 for clamping the connecting column 1321 of the guide pin 132, so that the guide pin 132 is coupled to the handle portion 108 and cannot move; the inner sleeve 136 surrounds the periphery of the screw rod 124, The inner sleeve 136 is coupled to the handle portion 108, one end of the guide pin 132 is connected to the inner sleeve 136, and the other end extends into the double helical groove on the screw 124; the guide pin 132 includes a connecting column 1321, which extends into a clamping hole formed by the inner sleeve 136 and the upper cover 129 and is clamped, and the guide pin 132 also includes an arc portion 1322 connected to the connecting column 1321, and the curvature of the arc portion 1322 is adapted to the screw 124, so that the arc portion 1322 can fit the groove wall of the double helical groove as much as possible when extending into the double helical groove of the screw 124, thereby ensuring that the guide pin 132 cooperates with the screw 124 to achieve smooth rotation and lifting of the screw 124.

[0047] Figure 2 In this embodiment, the screw 124 is rotated by the rotary motor 107 or electric machine through the torque receiving structure 150, which allows the screw 124 to move freely up and down when rotating. The screw 124 cooperates with the carrier 103 through the ball bearing 142 so that the screw 124 can impart reciprocating motion to the carrier 103, and the screw 124 imparts its rotational motion to the carrier 103.

[0048] Figure 2 In this embodiment, the load-bearing member 103 includes an inner sleeve and an outer sleeve, the inner sleeve having an opening 156, and the outer sleeve having corresponding linear guide grooves 144, which engage with the guide protrusions 148 of the nut to provide additional stability when the load-bearing member 103 is pulled upward and downward. A pair of conductive strips 135A and 135B can be arranged along the outer surface of the inner sleeve, and a pair of conductive scrapers 147A and 147B can protrude between the inner sleeve and the outer sleeve of the load-bearing member 103. The nested nature of the inner sleeve within the outer sleeve can act to press the conductive scrapers 147A and 147B against the conductive strips 135A and 135B, thereby forming a good electrical connection. In another embodiment, see Figure 7 and 8The bearing component 103 includes an outer sleeve 126, which surrounds the outer sleeve 136 and rises and falls with the screw 124; a detection device 1491 for detecting the lifting and falling stroke displacement of the outer sleeve 126 is provided between the outer sleeve 126 and the inner sleeve 136, and the detection device 1491 can be a travel switch, etc. Specifically, the top section of the through hole in the outer sleeve 126 is provided with a connecting portion 1261 rotatably connected to the stirring shaft on the screw 124, and the stirring shaft passes through the connecting portion 1261 on the outer sleeve 126 and passes through the first rolling bearing 141 The stirring shaft and the outer sleeve 126 are relatively rotatably connected, so that the outer sleeve 126 does not rotate with the stirring shaft, and the outer sleeve 126 can be lifted and lowered under the action of the screw 124. By setting a detection device 1491 between the outer sleeve 126 and the inner sleeve 136, the lifting stroke displacement of the outer sleeve 126 can be detected to feedback the control board 109, so as to prevent the screw 124 from rising too far and separating from the transmission shaft 140 on the rotary motor 107, and to prevent the screw 124 from falling too far and being squeezed and damaged by the annular base 151. In addition, the stirring shaft is connected to the vibration motor through the second rolling bearing 157, so that the vibration motor can swing with the stirring shaft. In addition, the torque receiving structure 150 is connected to the rotary motor 107 through the transmission structure, and is driven by the rotary motor 107 to drive the screw 124 to rotate. The screw 124 cooperates with the nut assembly to achieve lifting during the rotation process. At the same time, the torque receiving structure 150 has an inner cavity, and the transmission shaft 140 is inserted into the inner cavity. The shape of the transmission shaft 140 and the shape of the inner cavity are elliptical or runway, so that the transmission shaft 140 can drive the torque receiving structure 150 to rotate, and at the same time, the torque receiving structure 150 can be lifted and lowered with the screw 124. Figure 7 The head of the massage body 102 matches the swing amplitude of the massage component 101 so that the top of the head of the massage body 102 can press the skin.

[0049] Figure 4 is a cross-sectional view showing Figure 2 and Figure 3 As can be seen from the figure, the handle portion 108 includes a battery 110, a printed circuit board 118, a housing 119, a charging port 120, buttons 111A and 111B, and a rotary motor 107. The torque receiving structure 150 transmits the rotational force from the motor 107 to the screw 124, while allowing the screw 124 to move freely up and down. Figure 7 and 8The screw 124 has a double helical groove 131, and a part of the nut assembly is located in the double helical groove 131, that is, the arc portion of the guide pin 132 is located in the double helical groove 131, and when the screw 124 rotates, the nut assembly can continuously move in the double helical groove 131, so as to promote the screw 124 to rise and fall. The double helical groove 131 includes an ascending groove that drives the nut assembly to rise and a descending groove that drives the nut assembly to fall. The ascending groove and the descending groove are interlaced with each other, and the top of the ascending groove is connected to the top of the descending groove, and the bottom of the ascending groove is connected to the bottom of the descending groove, so as to ensure that the screw 124 can be lifted and lowered when rotating in one direction. The stretchable tube 106 connects the outside of the handle part 108 with the massage body 102.
