The sanitary cup includes a cup for collecting liquid, and A discharge pipe communicating with the bottom of the cup body, a discharge hole provided on the side wall of the discharge pipe; and a switching device acting on the discharge pipe to control the flow of the liquid through the discharge pipe to be discharged from the discharge hole. It should be noted that the bottom of the cup in this embodiment is not limited to only the portion of the cup that is farthest from the mouth of the cup, but generally refers to the lower portion of the side wall of the cup. In the course of use, it generally includes a liquid collecting state (a state in which the sanitary cup is placed in the body to collect liquid such as menstrual blood) and a liquid discharging state (a state in which the liquid collected in the cup body is discharged); the specific use process is as follows:

In the liquid collecting state: the switching device is closed, so that the liquid cannot flow out through the discharge pipe from the discharge hole; then the cup body is placed in the human body, at this time, according to the specific setting of the switch device, the material selection and the user's usage habits, etc. The switch device portion is also placed in the human body. Of course, it is also possible to choose not to place the portion provided with the switch device in the human body. Similarly, the discharge hole provided on the discharge pipe can also be selected or placed in the human body according to the actual situation. However, in consideration of the comfort of use, the present embodiment can preferably use an elastic and flexible material to make a switch device, a discharge tube, etc., so that the entire sanitary cup can be placed in the human body so that the user does not touch the switch device. There is no foreign body sensation, and the reliability is improved, and the user experience is also improved. During the liquid collection process, liquid such as menstrual blood flows into and is stored in the cup of the sanitary cup. It can be understood that, depending on the position of the switch device, there may be part of the liquid stored in the discharge pipe above the switch device. . In the liquid discharging state, the user pulls the switch device out of the human body, and the user can pull the switch device out of the human body by pulling the discharge pipe.

It should be noted that in this embodiment, only the portion of the switch device and the discharge tube provided with the discharge hole can be pulled out of the human body, and the other parts of the cup of the sanitary cup can still stay in the human body, and then will be located outside the body. The switching device is turned on to allow the liquid stored in the cup to flow through the discharge pipe to be discharged from the discharge hole in the discharge pipe. After the liquid discharge of the cup body is completed, the user turns off the switch device, and then pushes the switch device into the human body, so that the cup body is located at the corresponding part of the human body. Of course, when the switch device is located outside the body during the liquid collection process, the switch device can be directly opened for draining, and the switch device can be turned off after the draining is completed.

It can be seen that when the sanitary cup is provided in the embodiment, the user only needs to pull the switch device out of the human body and turn it on or directly open the switch device located outside the body to discharge the liquid. After the draining is completed, the switch device is turned off and then It can be pushed back into the body, does not need frequent cleaning, and is not easy to soil the user's hand. It is easier and more convenient to use than the existing sanitary cup, and there is no restriction on the place to be used. The user does not need to carry the spare sanitary cup or Its replacement, while also avoiding the cleaning of the hygiene cup in public, can greatly improve the user's satisfaction and willingness to use, and is more conducive to the promotion of the health cup.

In the embodiment, the setting of the switch device can be performed by the discharge pipe to control the liquid flowing through the discharge pipe to discharge from the discharge hole on the discharge pipe. Preferably, the setting of the switch device can also be conveniently placed in the human body. The requirements to improve the user experience. In this embodiment, the specific position and form of the switch device are not strictly limited. For example, the installation position may be disposed in the pipe of the discharge pipe, or may be disposed outside the pipe of the discharge pipe, and may be disposed inside and outside the discharge pipe. The two side walls or a part thereof are disposed between the inner and outer walls; the arrangement may be a valve, a piston, a clamping device, a pressing device, a sleeve, a collar, or a magnetic switch, a flexible switch, etc.; Integrated with the discharge pipe, it can also be molded separately; the switch device can control whether the liquid can be removed from the discharge hole on the discharge pipe by controlling the closing and circulation of the discharge pipe hole above the discharge hole; The opening and closing of the discharge hole on the pipe to control whether the liquid can flow out from the discharge hole. Similarly, in this embodiment, there is no strict restriction on the number, position, shape, and the like of the discharge holes provided on the side wall of the discharge pipe; of course, when the discharge hole is opened on the side wall of the discharge pipe, according to the specificity of the switch device In the form of setting, etc., a discharge hole can also be opened at the bottom of the discharge pipe. For a better understanding, the present invention will be further described in detail below with reference to the accompanying drawings.

When the switching device is disposed in the discharge pipe and the fluid discharge is controlled by controlling the opening and closing of the discharge hole located above the discharge pipe, a closed area may be disposed in the discharge pipe above the discharge hole, and a discharge area is disposed below the discharge hole in the discharge pipe. An opening area; the switching device may include a piston disposed in the discharge pipe, and when the piston moves from the opening region in the discharge pipe to the closing region above the discharge hole, the piston partially closes the discharge pipe above the discharge hole, and the discharge pipe is disposed thereon The discharge hole is separated by the piston, and the switch device is in the closed state; when the piston moves from the closed area above the discharge hole to the open area below the discharge hole, the discharge pipe communicates with the discharge hole provided thereon, at this time, the switch The device is on. Specifically, the manner of setting the above switch device and the discharge hole will be described below with reference to specific drawings:

Referring to Figure 3, the sanitary cup includes a cup 31, a discharge tube 32 that communicates with the bottom of the cup 31, and the discharge tube 32 also functions as a pull handle provided on the existing sanitary cup. The discharge pipe 32 is further provided with a discharge hole 321 , and the discharge hole 321 can be provided one or two or more according to actual conditions. The discharge hole 321 can be specifically set as a circular discharge hole, or can be set as When any of the plurality of discharge holes 321 is provided in any other shape such as an elliptical shape, a rectangular shape, or a rhombus shape, each of the discharge holes may be disposed at the same height of the discharge pipe, and may be further disposed to be evenly distributed. The arrangement position and specific distribution of each discharge hole are not limited to this one. For better drainage, the discharge hole 321 in the present embodiment is preferably a through hole that extends obliquely downward from the inner wall of the discharge pipe 32 to the outer wall of the discharge pipe 32. Similarly, the shape of the discharge pipe 32 in this embodiment may also be selected according to actual conditions. For example, the discharge pipe 32 may preferably have a circular or elliptical cross section, and the pipe hole may be circular or elliptical. Moreover, for better drainage, the liquid in the cup 31 flows into the discharge pipe 32 more smoothly, and flows out from the discharge hole 321 . In the embodiment, the inner diameter of the nozzle at the end of the discharge pipe 32 communicating with the cup 31 can be The inner diameter of the nozzle is larger than the bottom end of the discharge pipe 32 to allow the liquid in the cup 31 to flow more smoothly into the discharge pipe 32. Referring to FIG. 3, the piston in this embodiment may be a spherical piston 33, specifically a spherical piston or an elliptical spherical piston. In order to form a close fit between the spherical piston 33 and the discharge pipe 32, the diameter of the spherical piston 33 is slightly larger than the discharge. The diameter of the tube 32. In the discharge pipe 32, a region above the discharge hole 321 and below the cup body 31 may be provided as a closed region, and a region below the discharge hole 321 and above the bottom end of the discharge pipe 32 may be provided as an open region.

In addition, in order to achieve better sealing performance and to make the operation more convenient, referring to FIG. 4 and FIG. 5, on the basis of the sanitary cup shown in FIG. 3, the switching device may further include at least one in the closed region of the discharge pipe 32. A first positioning groove 34 formed on the inner wall, the shape and size of the first positioning groove 34 is matched with the piston, that is, the spherical piston 33; the spherical piston 33 is moved from the opening region in the discharge pipe 32 to the closed region in the discharge pipe 32. When it falls into the first positioning groove 33, it forms a close fit with the first positioning groove 33. As shown in FIG. 4, only one positioning groove 33 is provided. According to actual needs, a plurality of first positioning grooves 33 may be selected, and when one of the first positioning grooves 33 is used for a long time, it cannot be guaranteed to form with the spherical piston 33. When the mating is tight, other spare first positioning grooves 33 can be used to cooperate with the spherical piston to improve the reliability. According to the sanitary cup shown in Figures 3 to 5, the bottom of the discharge tube 32 can be arranged to be packaged or open, i.e., the bottom of the discharge tube 32 can also be provided with the same opening as the tube hole. At the same time, in order to make the operation more convenient, it is further selected to form at least one second positioning groove 35 on the inner wall of the opening region of the discharge pipe, and the second positioning groove 35 can also have a size matching with the piston, that is, the spherical piston 33; When the spherical piston 33 moves from the closed region to the open region, it falls into the second positioning groove 35 to form a close fit with the second positioning groove. Further, in order to prevent the piston from moving into the cup 31 via the discharge pipe 32, a limiting member may be disposed on the first positioning groove 34, and the limiting member is arranged to block the piston from the discharge pipe 32 into the cup body. mobile. It can be understood that the limiting member can be arranged in a plurality of manners. For example, the limiting member can be a blocking member additionally disposed on the inner wall of the discharge pipe, or can be configured by directly setting the inner diameter of the pipe hole at the corresponding position of the discharge pipe. The action of the limit position, such as the limit member 36 in FIGS. 4 and 5, is only one of the arrangement manners, as long as the set limit member can block the spherical piston 33 from entering the cup body, and at the same time, the discharge pipe 32 can be set to the limit. The tube hole at the position of the piece is not completely closed.

The manner in which the piston is disposed in the discharge pipe is not limited to the manner shown in FIG. 3 to FIG. 5. For example, the present invention will be further described by taking another embodiment in which the switch device is disposed in the discharge pipe, as shown in FIG. 6 and Figure 7, the sanitary cup includes a cup 31, a discharge tube 32 that communicates with the bottom of the cup 31. The bottom of the discharge pipe 32 is provided with a discharge hole 37. Of course, the discharge hole can also be disposed on the side wall of the discharge pipe. In the embodiment, the lower end of the discharge pipe 32 is disposed above the discharge hole 37 and further has a receiving cavity 38. The diameter of the chamber 38 is larger than the diameter of the tube hole of the discharge tube 32 above the accommodating chamber 38; the piston included in the switching device may also be a spherical piston 33, specifically a spherical piston or an elliptical spherical piston, in order to make the spherical piston 33 The discharge tube 32 forms a tight fit. In the present embodiment, it is preferable to provide the diameter of the spherical piston 33 slightly larger than the diameter of the discharge tube 32 in the tube hole above the accommodating chamber 38, and smaller than the diameter of the accommodating chamber 38. A limiting member is disposed on the piston 33, and the limiting member is configured to position the piston in the hole above the accommodating cavity 38 when the switching device is in the closed state, and form a tight fit with the discharge pipe when the switch device is in an open state. The piston is placed in the accommodating chamber 38. As shown in the figure, the limiting member in the embodiment is provided as a connecting belt 331. One end of the connecting belt 331 is fixed on the inner wall of the cup body 31 or the inner wall of the discharge pipe 32, and the other end is fixed on the piston 33 in the closed state. When the piston 33 is engaged with the discharge pipe 32 in the pipe hole above the accommodating cavity 38, the pipe hole of the engaging portion is closed; in the open state, the piston 33 falls into the discharge pipe 32 under the action of the pressing force. In the lower accommodating chamber 38, and under the action of the connecting belt 331, it stays in the accommodating chamber 38. Since the diameter of the piston 33 is smaller than the diameter of the accommodating chamber 38, it cannot form a sealing fit with the accommodating chamber 38. The liquid can flow out from the gap between the piston 33 and the accommodating chamber 38 and is removed through the discharge hole 38. When it is necessary to close, the piston 33 is pressed from the accommodating cavity 38 to the upper side of the discharge pipe 32 to form a sealing fit with the pipe hole above the engaging and accommodating cavity 38.

Of course, as shown in FIG. 4, at least one first positioning groove 34 may be formed on the inner wall of the pipe hole above the receiving cavity 38. The shape and size of the first positioning groove 34 and the piston are spherical pistons. When the spherical piston 33 moves from the accommodating cavity 38 in the discharge pipe 32 to the pipe hole above it, it falls into the first positioning groove 33 and forms a close fit with the first positioning groove 33. This method is more convenient for user identification during positioning. In this embodiment, a limiting member for blocking the drop of the piston 33 to block the hole below the accommodating cavity 38 may be directly disposed in the accommodating cavity 38, for example, a mesh limit may be disposed in the accommodating cavity 38. The positional member or the like can ensure that the piston 33 finally stays in the accommodating chamber 38 and leaves a sufficient discharge gap between the accommodating chamber 38 and the accommodating chamber 38.

The above-described setting of the switching device is described by taking the piston method as an example, and the following description will be made in the form of a valve. When the switching device is set as a valve, the discharge hole may be disposed on the side wall of the discharge pipe or at the bottom of the discharge pipe, and may also be provided with a discharge hole at the side wall or the bottom of the discharge pipe. The switch device may include a switch valve disposed in the discharge pipe and located above the discharge hole. When the switch valve is in the closed state, the pipe hole of the discharge pipe is sealed to block the liquid in the cup body from flowing out of the discharge pipe and being discharged from the discharge hole; When it is in the open state, the pipe hole of the discharge pipe is not completely sealed, so that the discharge pipe is in a circulation state, and the discharge pipe is circulated between the discharge pipe and the discharge hole provided thereon. The switch valve in the embodiment is a specific elastic valve device, as shown in FIG. 8 : the sanitary cup includes a cup body 61, a discharge pipe 62 communicating with the cup body 61, and a discharge hole provided on the side wall of the discharge pipe 62 (not shown) It is shown that the bottom of the discharge pipe can be set to be closed at this time, and the opening and closing valve 64 is disposed in the discharge pipe 62. The opening and closing valve 64 is an elastic member, and when the switch valve 64 is pressed in one direction of the discharge pipe 62, the switch The valve 64 is in a closed state to completely close the tube bore of the discharge tube 62. When the switch valve 64 is squeezed in the other direction, the switch valve 64 is in an open state to allow the discharge tube 62 to be in a flow state. The specific setting form of the switch valve in this embodiment can also be selected according to actual conditions. The present invention will be further described below by taking a specific arrangement mode of the switch valve as an example.

Referring to FIG. 9 and FIG. 10, the switch valve 64 includes a valve seat 641. The valve seat 641 can be a spherical valve seat or a cylindrical valve seat matched with the shape and size of the discharge pipe hole; a through hole, the through hole is a flow hole 643; the side wall of the flow hole 643 is made of an elastic material, for example, a material such as silica gel, which is deformed when subjected to an external force; and the switch valve further includes a spring disposed on both sides of the flow hole The member 642; the elastic member 642 is in a contracted state when subjected to an external pressure, and the flow hole 643 is in a flow state at this time, as shown in FIG. 7; when the elastic member 642 is subjected to an external pressure, the inner wall of the flow hole 643 is received. The force is deformed under the pressing of the elastic member 642, so that the flow hole 643 is closed, as shown in FIG. Therefore, it is possible to control the flow of the liquid through the discharge pipe 62 from the discharge hole by controlling the circulation and closing of the flow hole 643 of the switch valve 64.

The switch valve can also be set as shown in Figure 11. The discharge hole is disposed at a side wall of the discharge pipe 62 and/or a bottom of the discharge pipe, and the switch device is a switch valve 65 disposed in the discharge pipe 62 above the discharge hole 63. The switch valve 65 is an elastic member and can be connected with the discharge pipe 62. It is integrally provided; it can also be separately provided separately from the discharge pipe 62. The switch valve 65 is an elastic member in which a flow hole is provided in the middle, and other portions can be solid. The opening 651 above the flow hole and the opening 652 below are closed under normal conditions. When the switch valve 65 is subjected to an intermediate pressing force, the opening 651 above the flow hole and the opening 652 below are opened, and the flow hole provided in the switch valve 65 is circulated, thereby allowing liquid to pass through the flow hole. The discharge hole 63 is discharged. Of course, it is also possible to provide only the opening 651 above the flow hole in a closed state in a normal state, and the lower opening 652 is in an open state at any time. At this time, it is only necessary to control the closing and opening of the opening 651 above the flow hole as described above. Just fine.

For another example, when the switching device is disposed in the tube to control the discharge state of the discharge hole by controlling the opening and closing of the pipe hole, the following arrangement may be further provided: the discharge hole is disposed on the side wall of the discharge pipe, and the switching device above the discharge hole includes a first elastic member and a second elastic member disposed in the discharge pipe, wherein the first elastic member and the second elastic member are provided with a circulation hole, and the circulation hole is always in an open state, and the first elastic member and the second elastic member are discharged The bottom surface of the first elastic member is closely matched with the top surface of the second elastic member. When the state is closed, there is no overlap between the flow hole on the first elastic member and the flow hole of the second elastic member. When opening, the first elastic member and the second elastic member have a relative pressing force, so that the flow holes on the first elastic member completely overlap or partially overlap the flow holes of the second elastic member, thereby realizing the discharge tube hole The portion through which the fluid flows through the flow hole on the first elastic member and the flow hole of the second elastic member is discharged through the discharge hole in the discharge pipe.

Each of the above examples is described by taking a control device provided in the discharge pipe as an example. The switching device of the present invention can also control the discharge of fluid by directly controlling the discharge holes provided at the side or bottom of the discharge pipe.

Blocking. When it is necessary to open, just move the piston down to let out the discharge hole. When a flow hole is provided in the middle of the piston, the piston can move up and down when it is opened, as long as the discharge hole can be given out.

The switch device of the present invention can be disposed outside the discharge pipe and disposed outside the discharge pipe, and can also control the discharge state of the fluid by controlling the pipe hole of the discharge pipe or directly controlling the discharge hole. The invention will be further described below by taking several kinds of switching devices to set the outside of the discharge pipe as an example.

One arrangement is as follows: a discharge hole is arranged at a side wall and/or a bottom of the discharge pipe, and the switch device is disposed above the discharge hole outside the discharge pipe, and when the switch device is in a closed state, the discharge pipe is forced by the switch device. The deformation is thereby formed into a closed state; when the switching device is in an open state, the discharge pipe is in a circulating state. Referring to Fig. 12, the sanitary cup includes a cup body 91, a discharge pipe 92 communicating with the cup body 91, and a discharge hole is provided on the side wall of the discharge pipe 92 (not shown in the drawing, and a discharge hole may be provided at the bottom of the discharge pipe 92). Alternatively, the bottom portion thereof is closed, and a switching device 94 disposed outside the discharge pipe 92 at the upper portion of the discharge hole 93 is provided. As long as the switching means 94 achieves a force to the discharge pipe 92, the portion where the discharge pipe 92 is in contact with the switching device 94 is deformed into a structure as shown in Fig. 13, that is, the partial discharge pipe 92 is closed. Therefore, the specific structure of the switching device 94 is not limited in the embodiment, as long as the above functions can be realized, for example, a dedicated soft clip or the like. When the liquid is collected, the switching device 94 is closed, so that the portion of the discharge pipe 92 that acts with it is closed as shown in FIG. 13; when the liquid is drained, the switching device 94 is opened, and the portion of the discharge pipe 92 that acts with it is returned to the normal state.

In order to make the closure more reliable, a ring can be arranged. The inner diameter of the package sleeve 113 is slightly smaller than the outer diameter of the discharge tube 112 where the discharge hole 1121 is provided. In this arrangement, the switching device can directly act on the discharge hole 1121 provided on the discharge pipe 112, and the design is simpler and more practical. When the sanitary cup is placed in the body to collect the liquid, the annular package sleeve 113 is placed on the discharge tube 112 at a position where the discharge hole 1121 is provided, the discharge hole 1121 is effectively closed, and the whole of the sanitary cup is placed in the human body. When the liquid discharge is required, the end of the discharge pipe 112 is pulled by hand, the annular package cover 113 is pulled out of the body, and then the annular package cover 113 is moved up or down along the discharge pipe 112 to expose the discharge hole 1121. The liquid in the cup body 111 flows through the discharge pipe 112 through the discharge hole 1121. Of course, in addition to moving the annular package sleeve 113 up or down along the discharge pipe 112 to open or close the discharge hole 1121, a through hole 1131 matching the discharge hole 1121 may be disposed at a corresponding position on the annular package sleeve 113, The inner diameter of the through hole 1131 is preferably larger than the discharge hole 1121. As shown in FIG. 15, this arrangement can rotate the annular package sleeve 113 back and forth along the axial direction of the discharge pipe 112 (see the direction indicated by the arrow in the figure). In order to achieve the purpose of opening or closing the discharge hole 1121, and this arrangement can also move the annular package sleeve 113 up or down along the discharge pipe 112, the purpose of opening or closing the discharge hole 1121 can also be achieved.

Of course, in addition to the above-mentioned collar, the discharge hole is directly closed by the control mode, and a piston of a size matching with each of the discharge holes can be provided to control the opening state of the discharge hole. At this time, when the discharge hole needs to be closed, the piston can be directly inserted into the discharge hole on the side wall, and when it is required to be opened, it can be removed.
