[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. It should be understood that the specific embodiments described in this section are only used to explain the present invention and are not intended to limit the present invention.

[0032] In the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can be directly connected or indirectly connected through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature, as shown in the accompanying drawings.

[0033] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 As shown, a condom wearing device 100 provided by a preferred embodiment of the present invention is used to assist male users in wearing condoms 200 during sexual intercourse. The condom wearing device 100 includes a chuck 110, a sleeve assembly 120, a second transmission mechanism 130, a negative pressure assembly 140, a top cover 160, and a bottom cover 170. The chuck 110 is provided with a mounting hole 111, four clamping assemblies 112 (preferably at least three clamping assemblies 112), a first transmission mechanism 113, and a start switch 116. The four clamping assemblies 112 are evenly distributed around the mounting hole 111 for clamping the port 210 of the condom 200. The first transmission mechanism 113 can drive the clamping assemblies 112 to move radially toward the mounting hole 111 to slightly stretch the port 210. In other embodiments, the number of clamping assemblies 112 can also be three, five, or six.

[0034] like Figure 2 、 Figure 5 As shown, sleeve assembly 120 has a cavity 1211 for accommodating a human penis and an open end 1212. Open end 1212 is located within mounting hole 111 (or alternatively, below). The size of open end 1212 is smaller than the size of port 210 after it is stretched. Open end 1212 is provided with an opening 1213 that communicates with cavity 1211. Opening 1213 is used to allow a human penis to be inserted into cavity 1211.

[0035] like Figure 2 、 Figure 4 、 Figure 6As shown, the second transmission mechanism 130 is used to drive the sleeve assembly 120 to move along its axial direction so that the open end 1212 passes through the mounting hole 111 until the port 210 is separated from the clamp assembly 112 and buckled on the outer surface of the open end 1212 .

[0036] Specifically, if Figure 4 As shown, the second transmission mechanism 130 includes a second motor 131, a second gear 132 and a rack 133 meshing with the second gear 132. The rack 133 is fixed to the side of the outer sleeve 122. The second motor 131 drives the second gear 132 to rotate to move the sleeve assembly 120 along its axial direction.

[0037] like Figure 5 、 Figure 6 As shown, the negative pressure assembly 140 includes an air pump 141 and an air release valve 142, which are connected to the exhaust port 1214 via a pipe 150. The negative pressure assembly 140 is used to extract air from the cavity 1211 to deploy the condom 200 within the cavity 1211. Specifically, the air pump 141 is used to draw air from the cavity 1211, and the air release valve 142 is used to connect the cavity 1211 to the outside world after the air pump 141 has operated for a preset time (5 seconds), thereby preventing the condom 200 from being in a negative pressure environment for a long time.

[0038] like Figure 1 、 Figure 2 、 Figure 3 As shown, top cover 160 is used to cover chuck 110 to prevent dust from sticking to condom 200. In this embodiment, top cover 160 is provided with a through hole 161, located above mounting hole 111. Through hole 161 is larger than the size of open end 1212, allowing open end 1212 to extend out of through hole 161. Lower cover 170 is fixedly connected to the bottom of chuck 110. Second transmission mechanism 130, negative pressure assembly 140, and pipeline 150 are all concealed within lower cover 170.

[0039] like Figure 3 、 Figure 4 、 Figure 10 As shown, the chuck 110 further includes a base 114, a turntable 115 and a limiting block 119, wherein the limiting block 119 is used to limit the radial movement of the turntable 115. A slide rail 1141 is provided on the base 114, and the turntable 115 can be driven by the first transmission mechanism 113 to rotate relative to the base 114 at a predetermined angle. Figure 7 、 Figure 11As shown, the bottom of the clamp assembly 112 is provided with a slider 1121 and a connection point 1122 that mate with a slide rail 1141. Slider 1121 can move along the slide rail 1141, and connection point 1122 is movably connected to the turntable 115, allowing it to be moved radially toward the mounting hole 111 by the turntable 115. A slanted groove 1151 is provided on the turntable 115 that mates with connection point 1122. When the turntable 115 rotates, the force component of slanted groove 1151 causes connection point 1122 to move within slanted groove 1151, allowing slider 1121 to slide on the slide rail 1141. Slanted groove 1151 acts to reduce the force applied to port 210, preventing damage to port 210.

[0040] like Figure 4 As shown, the first transmission mechanism 113 includes a first motor 1131, a first gear 1132, and a plurality of meshing teeth 1133. The center of the first gear 1132 is connected to the output shaft of the first motor 1131. The plurality of meshing teeth 1133 are fixed to the turntable 115, and the tooth clearances of the plurality of meshing teeth 1133 match those of the first gear 1132. The first motor 1131 is configured to rotate the first gear 1132. When the first gear 1132 rotates, the engagement between the first gear 1132 and the plurality of meshing teeth 1133 rotates the turntable 115, thereby causing the clamp assembly 112 to move radially. In this embodiment, the plurality of meshing teeth 1133 are distributed around the periphery of the turntable 115.

[0041] like Figure 2 、 Figure 8 As shown, the sleeve assembly 120 also includes an inner sleeve 121, an outer sleeve 122 and a spring 123. The outer sleeve 122 is sleeved on the outside of the inner sleeve 121, and the outer sleeve 120 and the inner sleeve 110 are clearance-fitted. The cavity 1211 and the open end 1212 are both provided on the inner sleeve 121. The spring 123 is connected to the bottom space of the inner sleeve 121 and the outer sleeve 122 so that the open end 1212 extends out of the outer sleeve 122. After the spring 123 is compressed, the open end 1212 can extend into the outer sleeve 122. Specifically, as shown in FIG. Figure 5 、 Figure 10 As shown, the bottom of the inner sleeve 121 is provided with a guide column 1216, and the bottom of the outer sleeve 122 is provided with a receiving tube 1221 at a position corresponding to the guide column 1216. One end of the guide column 1216 is inserted into the receiving tube 1221. The spring 123 is sleeved on the outer surface of the guide column 1216. The two ends of the spring 123 are respectively in contact with the end surfaces of the inner sleeve 121 and the receiving tube 1221. When the spring 123 is compressed, the inner sleeve 121 is caused to perform telescopic movement relative to the outer sleeve 122. Figure 5As shown, the outer wall of the inner sleeve 121 is provided with a snap-fit ​​1215, located at the open end 1212. When the port 210 is buckled onto the outer surface of the open end 1212, the port 210 is snapped into the snap-fit ​​1215. An exhaust port 1214 is provided at the bottom of the inner sleeve 121. The negative pressure assembly 140 passes through the bottom of the outer sleeve 122 via a pipe 150 and is connected to the exhaust port 1214, thereby communicating with the cavity 1211 to extract air from the cavity 1211, creating a negative pressure within the cavity 1211 and causing the condom 200 to unfold.

[0042] Specifically, the steps for using the condom donning device 100 in this embodiment are roughly as follows:

[0043] a. Remove the top cover 160.

[0044] b. Take out the condom 200, and then clamp the end 210 of the condom 200 with four clamp assemblies 112 (e.g. Figure 9 shown).

[0045] c. After closing the top cover 160, press the start switch 116 (the start switch 116 is used to energize the first motor 1131 and the second motor 131 and start working according to the program settings). The first gear 1132 rotates the turntable 115 to a certain angle under the action of the first motor 1131. The four clamping assemblies 112 push the slider 1121 along the slide rail 1141 under the component force of the inclined slot 1151 until the port 210 of the condom 200 is slightly opened.

[0046] d. Driven by the second motor 131, the second gear 132 moves the outer sleeve 122 and the inner sleeve 121 upward along the axis. After the top of the inner sleeve 121 contacts the condom 200, it continues to move upward for 2 cm until the port 210 is separated from the clamp assembly 112 and buckled onto the outer surface of the open end 1212. At this time, the condom 200 is tightly combined with the open end 1212 of the inner sleeve 121, and the open end 1212 is in a sealed state.

[0047] e. The air pump 141 starts working to extract the air in the cavity 1211 , and the condom 200 unfolds along the inner wall of the inner sleeve 121 under negative pressure.

[0048] f. The air pump 141 stops working after working for 5 seconds, and the air relief valve 142 starts working (the air relief valve 142 opens), allowing the cavity 1211 to communicate with the outside world.

[0049] When using the condom donning device 100, the user simply aligns the penis with through-hole 161 and inserts it until the penis reaches the bottom, then pushes the inner sleeve 121 forward. Because the bottoms of the inner sleeve 121 and outer sleeve 122 are connected by spring 123, the inner sleeve 121 compresses the spring 123, causing the inner sleeve 121 to retract into the outer sleeve 122 until the condom 200, which is buckled against the open end 1212, falls off from the open end 1212 under the thrust of the end surface of the outer sleeve 122, and the condom 200 is firmly attached to the penis. After sensing that the penis has been removed from the cavity 1211, the condom donning device 100 controls the various transmission mechanisms to return to their original positions.

[0050] Since the chuck 110 can fix the condom 200, the sleeve assembly 120 rotates the condom 200 to the open end 1212 under the drive of the second transmission mechanism 130, and the negative pressure assembly 140 can extract the air in the cavity 1211 to make the condom 200 unfold in the cavity 1211, so the user does not need to find a condom to put on during sexual intercourse. He only needs to prepare the condom for next use on the chuck 110 in advance to quickly put on the condom, thereby solving the problem of the troublesome and unhygienic problem of putting on condoms during sexual intercourse.

[0051] The above specific examples illustrate the principles and implementation methods of the present invention. It should be understood that the above implementation methods are only used to facilitate understanding of the present invention and should not be construed as limiting the present invention. For those skilled in the art, any minor improvements or equivalent substitutions made to the structural form or construction of the present invention based on the principles of the present invention should be included within the scope of its protection.
