[0034] like Figures 1 to 6 As shown, the utility model provides a vagina care and flushing device.

[0035] Specifically, by Figure 1-3 The invention provides a squeezing bottle 1 and an inner nozzle 2, wherein a bottle cap 101 is arranged on the top of the squeezing bottle 1, one end of a connecting tube 102 is arranged on the bottle cap 101, the other end of the connecting tube 102 is connected to the inner nozzle 2, a side surface of the inner nozzle 2 is provided with a side spray hole 201, a top surface of the inner nozzle 2 is provided with a top spray hole 202, the outer side of the inner nozzle 2 is rotatably connected with a limiting sleeve 3, a side surface of the limiting sleeve 3 is provided with a side through hole 301 adapted to the side spray hole 201, a top through hole 302 adapted to the top spray hole 202 is provided on the top surface of the limiting sleeve 3, and a bottom through hole 303 is provided on the bottom surface of the limiting sleeve 3.

[0036] In the utility model, by adopting the above-mentioned design, when the user performs vaginal care, the care liquid can be sent into the connecting tube 102 by pressing the squeeze bottle 1, and then enters the inner nozzle 2 through the connecting tube 102, and finally sprayed out from the side spray hole 201 and the top spray hole 202 on the inner nozzle 2, and the surroundings and deep parts are flushed at the same time, which is faster and has a more comprehensive range. In addition, according to the needs of the user, the limit sleeve 3 can be selectively rotated to make the top through hole 302 and the top spray hole 202 misaligned to block the top spray hole 202, so that the care liquid can only be sprayed out from the side through hole 301, reducing the number of spray holes, making the care liquid flow faster at the same pressing force, so as to improve the flushing depth of the device, and after all the care liquid in the squeeze bottle 1 is sent out, the squeeze bottle 1 can be pulled in the opposite direction, so that most of the care liquid in the vagina will be sucked back by the squeeze bottle 1 through the side through hole 301, making the use of the device more convenient.

[0037] Furthermore, as a specific implementation of the present utility model, the present utility model provides a vaginal care and flushing device.

[0038] Specifically, Figure 1-3 As shown, the squeeze bottle 1 is made of medical plastic, and folds are arranged on the outer wall of the squeeze bottle 1.

A groove is arranged on the bottom surface of the bottle cap 101, and an internal thread adapted to the connecting block is arranged on the inner wall of the groove. The squeeze bottle 1 and the bottle cap 101 are threadedly connected via the connecting block and the groove.

[0039] In the utility model, by adopting the above-mentioned design, when the user presses the squeeze bottle 1, he can press along the direction in which the folds are set, flatten the folds to deliver all the care liquid in the squeeze bottle 1. The care liquid is delivered more thoroughly, and pressing along the folds also makes the process of delivering the care liquid more labor-saving. After use, the squeeze bottle 1 can be unscrewed from the bottle cap 101 and discarded, and then the bottle cap 101, the connecting tube 102, the inner nozzle 2 and the limiting sleeve 3 can be sent for cleaning and disinfection for next use, thereby saving costs.

[0040] Furthermore, as a specific implementation of the present utility model, the present utility model provides a vaginal care and flushing device.

[0041] Specifically, Figure 1-3 As shown, a connecting tube 102 is fixedly connected to the center of the top surface of the bottle cap 101, and a connecting hole adapted to the connecting tube 102 is opened at the center of the top surface of the connecting block.

[0042] In the utility model, by adopting the above-mentioned design, the care liquid in the squeeze bottle 1 can be sent into the connecting tube 102 from the connecting hole by squeezing, and the connection is sealed by the sealing gasket, so that the care liquid will not leak.

[0043] Furthermore, as a specific implementation of the present utility model, the present utility model provides a vaginal care and flushing device.

[0044] Specifically, Figure 1-3 As shown, the other end of the connecting pipe 102 is fixedly connected to the center of the bottom surface of the inner nozzle 2. A main water spray hole is opened in the inner nozzle 2, and the main water spray hole is connected to the side spray hole 201 and the top spray hole 202. The side spray holes 201 are divided into multiple groups in a circular array and are evenly spaced on the side of the inner nozzle 2, and each group includes multiple holes in a linear array and are evenly spaced on the side of the inner nozzle 2. The top spray hole 202 is divided into multiple groups in a circular array and are evenly spaced on the top surface of the inner nozzle 2, and each group includes multiple holes in a linear array and are evenly spaced on the top surface of the inner nozzle 2.

[0045] In the present invention, by adopting the above-mentioned design, the side spray hole 201 and the top spray hole 202 can spray the care solution from multiple positions at the same time, so that the range of a single care impact is improved, making the overall care flushing speed faster.

[0046] Furthermore, as a specific implementation of the present utility model, the present utility model provides a vaginal care and flushing device.

[0047] Specifically, Figure 1-3 As shown, the limiting sleeve 3 can only be rotated horizontally and is arranged on the inner nozzle 2. The opening position, number and size of the side through holes 301 are the same as those of the side spray holes 201. The top through holes 302 are divided into multiple groups and are evenly spaced in a circular array on the top surface of the limiting sleeve 3. Each group includes multiple holes evenly spaced in a linear array on the top surface of the inner nozzle 2. The number of groups of top through holes 302 is half of the top spray holes 202. The spacing between each group of top through holes 302 is four times the spacing between each group of side through holes 301. The bottom through hole 303 is opened at the center of the bottom surface of the limiting sleeve 3 for the connecting pipe 102 to pass through.

[0048] In the utility model, by adopting the above-mentioned design, the side spray hole 201 can be selectively completely blocked by rotating the limiting sleeve 3 by one-sixth of a circle to control the flushing range of the care solution, thereby better flushing and caring for the vagina. In addition, according to the user experience, the limiting sleeve 3 can be rotated a certain number of times to block part of the side spray hole 201 to adjust the flow rate of the care solution and improve the user experience.

[0049] Furthermore, as a specific implementation of the present utility model, the present utility model provides a vaginal care and flushing device.

[0050] Specifically, Figure 2-6 As shown, a positioning cavity 203 is provided on one side of the bottom surface, and two limiting grooves 204 are provided in the positioning cavity 203 along its center line.

A positioning plate 304 adapted to the positioning cavity 203 is provided on the inner bottom surface of the limiting sleeve 3.

[0051] In the present utility model, by adopting the above-mentioned design, the rotation range of the limit sleeve 3 is limited, and when the positioning plate 304 is rotated to the position where the side spray hole 201 can be blocked or opened at both ends of the positioning cavity 203, the positioning plate 304 will first contact the positioning protrusion 206, and then press the positioning protrusion 206 down along the arc surface on the positioning protrusion 206. At this time, the spring 207 will convert the force pressing down the positioning protrusion 206 into elastic potential energy and accumulate it. When the positioning plate 304 is fully advanced to one side of the positioning cavity 203, the spring 207 will convert the elastic potential energy accumulated previously into kinetic energy, driving the positioning protrusion 206 to reset until the limit block 205 conflicts with the limit groove 204, so that the position of the positioning plate 304 is fixed on one side of the positioning cavity 203 without human interference, which is further convenient for users.

[0053] By setting a limiting sleeve 3 that can only rotate horizontally on the inner nozzle 2, a side through hole 301 is opened on the limiting sleeve 3, and the opening position, number and size of the side through holes 301 are set in the same way as the side spray holes 201, and the top through holes 302 are divided into a plurality of groups that are opened in a circular array at equal intervals on the top surface of the limiting sleeve 3, each group of which includes a plurality of groups of top through holes 302 that are opened in a linear array at equal intervals on the top surface of the inner nozzle 2, and the number of groups of the top through holes 302 is half of the top spray holes 202, and the spacing of each group is four times that of the side through holes 301, so that the side spray holes 201 can be completely blocked by rotating the limiting sleeve 3 by one-sixth of a circle, so as to control the flushing range of the care solution and better flush and care the vagina, and the flow rate of the care solution can be adjusted according to the user experience by rotating the limiting sleeve 3 a certain number of times to block part of the side spray holes 201, thereby improving the user experience.

[0054] A positioning cavity 203 is provided on one side of the bottom surface of the inner nozzle 2, two limiting grooves 204 are provided in the positioning cavity 203 along its center line, a positioning protrusion 206 is provided in each limiting groove 204 so as to be only vertically slidable, the top of the positioning protrusion 206 is provided in a semicircular shape, a limiting block 205 is provided at the end of the positioning protrusion 206, one end of a spring 207 is fixedly connected to the bottom surface of the positioning cavity 203, the other end of the spring 207 is fixedly connected to the positioning protrusion 206, a positioning plate 304 adapted to the positioning cavity 203 is provided on the inner bottom surface of the limiting sleeve 3, so that the rotation range of the limiting sleeve 3 is limited, and when the positioning plate 304 is rotated to the positioning cavity 203, the limiting block 205 is provided at the bottom surface of the limiting sleeve 3. When the side spray hole 201 can be blocked or opened at both ends, the positioning plate 304 will first contact the positioning protrusion 206, and then press the positioning protrusion 206 down along the arc surface on the positioning protrusion 206. At this time, the spring 207 will convert the force pressing down the positioning protrusion 206 into elastic potential energy and accumulate it. When the positioning plate 304 is fully advanced to one side of the positioning cavity 203, the spring 207 will convert the elastic potential energy accumulated previously into kinetic energy, driving the positioning protrusion 206 to reset until the limit block 205 conflicts with the limit groove 204, so that the position of the positioning plate 304 is fixed on one side of the positioning cavity 203 without human interference, which further facilitates the user's use.
