Specific embodiments

[0040] Next, the technical solutions in the embodiments will be clearly and completely described in conjunction with the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments, rather than all of the embodiments.

[0041] In the embodiments, it should be understood that the orientation or positional relationships indicated by terms such as "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0042] In addition, in the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. Without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0043] Specifically, in the statement that "the connecting pipe connecting the urine receiving funnel and the urine receiving container extends upward from the urine receiving funnel connection part", the "upward" in "extends upward" does not refer to the "upward" in the traditional sense relative to the earth's gravity, but the "upward" relative to the human body layout, that is, the head is "upward" and the feet are "downward". No matter whether the human body is standing, sitting or lying, this relative direction is maintained, that is, "upward" is the direction towards the head. Embodiment

[0044] As Figure 1 , it is a schematic diagram of the basic structure of a negative pressure urine receiving device. Taking a relatively simple female portable type as an example, it includes a urine receiving funnel 10 and a urine delivery pipe 11 extending upward closely from the bottom of the urine receiving funnel. There is a flanging with a certain width inward at the opening of the urine receiving funnel 10, and a fluffy water absorption layer 12 similar to the water absorption cotton material of a disposable diaper is pasted on this flanging; the urine delivery pipe 11 leads directly to the lowest depression at the bottom of the urine receiving funnel 10, and this place is set as the liquid suction port; the portable use scenarios are standing or sitting postures, and the urine receiving funnel 10 is in the posture shown in the figure.

[0045] The urine receiving container 20 is a formed and sealed container. After the urine delivery pipe 11 extends upward from the urine receiving funnel 10, it leaves the human body and leads to the upper side of one side of the urine receiving container 20; the negative pressure generator 30 leads to the upper side of the other side of the urine receiving container 20 through a negative pressure connecting pipe 31; when the negative pressure generator 30 works, a certain negative pressure is formed in the urine receiving container 20, and this negative pressure is then conducted to the liquid suction port of the urine receiving funnel 10 through the urine delivery pipe 11, forming a certain negative pressure in the cavity of the urine receiving funnel 10; under the action of this negative pressure, external air enters the cavity of the urine receiving funnel 10 through the fluffy gaps of the water absorption layer 12 to form an air flow and reach pressure balance, avoiding discomfort caused by excessive negative pressure in the cavity of the urine receiving funnel 10 to the traction of human tissues, and at the same time avoiding deformation of the urine receiving container 20 caused by excessive negative pressure. At the same time, this air flow is also very small and almost imperceptible; when urinating, the urine converges to this low-lying liquid suction port by gravity and is then taken away by the urine delivery pipe 11 under the action of negative pressure and sent into the urine receiving container 20.

[0046] A flange with a certain width is arranged inward at the opening of the urinal 10. In addition to being convenient for the water-absorbing layer 12 to be attached thereto, a more important function is that the groove formed by the flange in the cavity of the urinal 10 can accumulate a certain amount of urine, thereby preventing the urine from overflowing if it is not absorbed in time when urinating is urgent.

[0047] The flange surface of the urinal 10 is configured to fit the curved surface of the female vulva, the skin-friendly material of the water-absorbing layer 12 makes the body feel comfortable, and the water absorption of the material can absorb a small amount of splashed urine. When the urination is completed and the urine is taken out, the urine remaining on the hair can be removed at the same time.

[0048] Figure 2 The portable male urinal has a chili-shaped curved tip with a narrow curved bottom portion as the liquid suction port, and a urine delivery tube 11 is connected to it and led upward; a fluffy water-absorbing layer 12 is attached to the inner ring of the opening; when urinating, it is put on the front end of the penis, and urine is gathered to the liquid suction port at the bottom of the tip by gravity, and then is taken away by the urine delivery tube 11 under the action of negative pressure and delivered to the urine receiving container 20; when urinating is completed and taken out, the water-absorbing layer 12 can also remove the urine remaining on the side of the glans penis. The portable male and female urinals can be made of common materials such as PVC and PET by blow molding to reduce costs. Due to the low cost, the portable urinal and urine delivery tube can be used as disposable, eliminating the trouble of cleaning.

[0049] Figure 3 Another embodiment is a schematic diagram of the structure of a nursing male urinal; the nursing type, as the name implies, refers to people who cannot take care of themselves, especially those who are bedridden for a long time. Unlike the portable type, the posture of the urinal will change with the different lying positions of the patient, so its liquid suction port must also change with different lying positions; the main material of the urinal in this embodiment is a rubber material, preferably silicone, which has good elasticity and skin-friendliness. The liquid suction port near the bottom of the tip is gradually thinned to make this part have higher flexibility and freedom. At the same time, a counterweight is set at the liquid suction port. The narrowed bend in the figure of this embodiment is the liquid suction port. The liquid suction port counterweight ring 13 is set at this position so that this part always hangs in a low position under the action of gravity, whether lying flat or lying on the side, the urine can be effectively discharged. The liquid suction port counterweight ring 13 can be made of corrosion-resistant high-density material, such as a rust-proof metal ring.

[0050] Since the nursing type is worn almost 24 hours a day, it must have a cleaning function to remove residual urine. An additional flushing liquid delivery pipe 14 is provided to pass through the front end of the urine receiving hopper 10 to form a cleaning liquid nozzle for flushing residual urine near the liquid suction port of the urinal.

[0051] Figure 4Schematic diagram of the structure of a female urinal for nursing use. In the figure, A is a cross-sectional view in the lying position. To achieve a better hanging effect, a liquid suction hose 111 led out from the urine delivery pipe 11 is added, and its end is connected to a liquid suction port weight ring 13. Here, the liquid suction port weight ring 13 is made into a spherical shape with through holes, which is convenient for rolling along with the patient when changing positions. The liquid suction hose 111 passes through the through hole and is fastened. The mouth of the spherical liquid suction port weight ring 13 is the liquid suction port of this embodiment, and several tooth-shaped notches are provided to prevent blockage (not shown in the figure); a splash-proof net 15 is added to prevent high-speed urine from splashing to the female vulva when impacting the bottom of the urinal. It can be made of a light mesh material and is fastened under the flanging of the urinal 10. The liquid suction hose 111 can be made of silicone tube, and the main body of the urinal can also be made of silicone material, but its hardness must take into account both the flexibility of fitting the human body and the firmness of maintaining the shape.

[0052] During urination, the urine sinks into the bottom groove after being buffered by the splash-proof net 15. Under the action of negative pressure, it enters through the through hole (liquid suction port) of the weight ring 13 and is then discharged through the liquid suction hose 111 into the urine delivery pipe 11; C in the figure is a partial cross-sectional view at the a-a position of Figure A. The illustrated state is equivalent to the left lateral position of the wearing patient. By combining Figures C and D, it can be seen that the weight ring 13 together with the liquid suction hose 111 hangs to the groove at the lowest point of the side arc of the urinal. At this time, when urinating, the urine will sink into the groove there and then be discharged through the through hole (liquid suction port) of the weight ring 13 and then through the liquid suction hose 111 into the urine delivery pipe 11; the situation of the right lateral position is similar and will not be elaborated here; for the convenience of drawing, the splash-proof net 15 is hidden in Figures B and D.

[0053] The flushing liquid delivery pipe 14 leads to the upper end of the urinal 10 to form a cleaning liquid spray nozzle. Appropriate treatments such as flattening should be done at the positions of the cleaning liquid spray nozzles for both male and female urinals so that the cleaning liquid can flush as much as possible the areas with residual urine in the urinal 10 (not shown in the figure). This is not the focus of this utility model and will not be elaborated here.

[0054] Figure 5This is a schematic diagram of the basic structure of the nursing type of the present utility model. This embodiment also takes the female device as an example for illustration: A cleaning liquid delivery device is added, including a cleaning liquid storage tank 40, a control board 41 and a water pump 42; The urine receiving container 20 can adopt a closed container with a larger capacity such as a urine pot or a urine bucket, and the negative pressure generator 30 adopts a long-life vacuum pump, which must be kept working with long-term opening; A cleaning liquid containing cleaning and aromatic components can be placed in the cleaning liquid storage tank 40, or it can also be clean water, which is collectively referred to as cleaning liquid; The release of the cleaning liquid can be realized manually, and this embodiment adopts unattended automatic control; First, the urination process is detected through a sensor. A simple method can be to infer by detecting the change in the working current of the vacuum pump. During the process of pumping urine, the load increases, and the current will be slightly larger than when only air is flowing; A more accurate method is to detect the process of urine flowing through the transparent urine delivery pipe 11 through a photoelectric sensor. This detection means can be easily realized by ordinary technical personnel in the electronics industry, and will not be illustrated and described in detail here; The control board 41 detects the urination process through the above means. After urination is completed, after a few seconds of interval, the control water pump 42 to work to send the cleaning liquid into the urine receiving funnel 10 through the cleaning liquid delivery pipe 14 and spray it out from the cleaning liquid nozzle to wash the residual urine on the inner wall of the urine receiving funnel. The mixed liquid after washing then enters the urine delivery pipe 11 through the through hole of the counterweight ring 13 and is discharged into the urine receiving container 20 through the liquid suction port hose 111; After the flushing is completed, the control board 41 controls the water pump 42 to stop working; The splash-proof net 15 can prevent the cleaning liquid from directly splashing onto the vulva and causing discomfort. At the same time, the cleaning liquid hitting the splash-proof net 15 can also wash away the residual urine on the splash-proof net; To improve the comfort of the human body, a temperature control device can be set in the cleaning liquid storage tank 40 to keep the cleaning liquid at a comfortable temperature for the human body, which also belongs to mature prior art and will not be elaborated further. The working process of the male urine receiving funnel is similar and will not be described separately.

[0055] To prevent the stench of urine from permeating the room, deodorization treatment should also be carried out on the air inlet or outlet of the negative pressure generator 30. There are many ready-made solutions in the prior art and will not be described separately; For the scenario of use in a hospital, the negative pressure generator 30 can be omitted and directly connected to the vacuum negative pressure interface at the head of the bed through a connector.

[0056] Since the connecting tubes of this solution are all led out from above and can be led out from the waist, unlike the traditional bottom-out type which must be led out from the trouser cuffs, it is extremely troublesome to put on and take off clothes; the fixing method can directly fix the urine collector 10 to the inside of the elastic tight underwear by sewing, gluing, etc. The advantage is that it is relatively firm, but it is inconvenient to clean. Therefore, in this embodiment, it is fastened to the elastic tight underwear through Velcro, that is, the fastening surface of the urine collector 10 is pasted with the hook surface of Velcro, and the corresponding position of the elastic tight underwear is sewn with the loop surface of Velcro (a very common and mature prior art, not shown). Through the wearing of the tight underwear, it can be reliably positioned at the appropriate position of the vulva, which is convenient to wear and not easy to move. At the same time, the comfort is better than the conventional strap-type fixing method; the fluffy water-absorbing layer 12 is occasionally slightly wet, and the water vapor is taken away due to the continuous airflow passing through, so it dries again. The water-absorbing layer 12 is pasted on the flange at the opening of the urine collector 10 through self-adhesive, and a replacement operation can be carried out once a day to prevent it from accumulating too much urine and causing discomfort.

[0057] In the portable usage scenario, the small size and convenience of the negative pressure generator 30 become crucial. Figure 6 This is a schematic diagram of the structure of the portable negative pressure generator of the present utility model. Its core component is a micro electric suction pump 32. Its power supply can adopt the external power supply method, but considering the convenience of being available at any time when urgent, in this embodiment, a lithium battery 33 is configured, which can be used as soon as it is turned on; through the control board 34, the external power supply can charge the lithium battery 33; the control board 34 is also equipped with output ports such as USB sockets and indicator lights, and can also serve as a mobile power supply; the control board 34 can also control the power supply to the electric suction pump 32, and automatically cut off the power after being turned on for a certain time to prevent the power from being exhausted due to forgetting to turn off the machine. When in use, just connect the negative pressure connecting tube 31 to the air inlet nozzle 321 and then turn on the machine.

[0058] Figure 7 This is a schematic diagram of the structure of the vehicle-mounted negative pressure generator of the present utility model. Due to the narrow space in the vehicle, the odor needs to be treated. A filter 35 is provided at the front end of the electric suction pump 32. The negative pressure connecting tube 31 is connected to the air inlet nozzle 351 of the filter. After the odor is filtered by the filter 35, it is then connected to the air inlet nozzle 321 through the filter connecting tube 352; the power supply is completed by inserting the cigarette lighter power take-off head 36 into the vehicle-mounted cigarette lighter. When in use, just connect the negative pressure connecting tube 31 to the air inlet nozzle 351 of the filter and then press the switch (not shown) to turn on the machine; the vehicle-mounted urine collector is the same and universal as the portable type. The filter 35 can be filled with porous adsorbent materials such as activated carbon, which is a mature prior art and will not be elaborated.

[0059] When going out, it is extremely inconvenient to carry hard bottles and jars as urine collection containers, and ordinary soft urine bags cannot withstand negative pressure. This embodiment uses the form of an air column bag to solve this problem. As Figure 8The urine collecting container 20 is enclosed by three rows of parallel air columns 21 to form a triangular prism, each side of which is sealed tightly, and the upper sealing area 22 seals two pipe nozzles 26 at a large interval. Before the sealing operation, a package of polymer water-absorbing curing agent 23 is placed, and the curing agent is sealed by a water-soluble film bag; in addition, the air columns can also be arranged in a spiral shape to form a cylindrical shape, but the manufacturing process is complicated.

[0060] The bag is in a deflated bag shape for easy carrying in normal state; when urinating, first turn on the power of the negative pressure generator 30 to put its electric suction pump 32 into working state, then insert its exhaust nozzle 322 into the air inlet of the air column bag to act as an air pump, so that each air column is filled with air and stands upright as shown in the figure; the triangular column air column bag can withstand a certain atmospheric pressure in an upright state without shrinking; then the urine delivery tube 11 and the negative pressure connecting tube 31 are respectively connected to the pipe connector 26; after the urine enters the bag, the water-soluble film melts, and the water-absorbing curing agent 23 reacts with the urine to form a gel to prevent leakage and prevent odor at the same time. The working principle and structure of the air column bag are mature existing technologies and will not be repeated. There is also a simple way, which is to seal the urine delivery tube 11 and the negative pressure connecting tube 31 directly into the upper sealing area 22, and the urinal 10 (for men and women), the urine delivery tube 11, the air column bag and the negative pressure connecting tube 31 can be made into a disposable component. When in use, the urinal 10 is passed through the waistband and inserted into the underwear and placed in the urination position without taking off the pants. After use, the negative pressure connecting tube 31 can be pulled out from the air inlet nozzle and discarded; in order to protect privacy, a simple non-woven apron can be configured to avoid embarrassment in front of others. In summary, the portable negative pressure urine collecting device is equivalent to a portable mobile toilet, which solves the worries.

[0061] Another solution for portable urine collection container is Figure 9 The urine receiving container is in the shape of a bag. In order to prevent the urine receiving bag 20 from shrinking under negative pressure, a support frame 24 is specially provided. The small support frame 241 and the large support frame 242 made of hard material are riveted together in the middle by support frame rivets 243. When not in use, the state is as shown in Figure A, and the small support frame 241 is folded in the large support frame 242; when in use, the small support frame 241 is rotated 90 degrees around the support frame rivet 243 to form a cross with the large support frame 242, and buckle sleeves 25 are evenly distributed on the four sides of the urine receiving bag 20. The four buckle sleeves 25 are put on the four supporting feet of the opened support frame to support the urine receiving bag 20 to the maximum and tighten the four sides; the buckle sleeves on the four sides of the urine receiving bag are stretched open by the four supporting feet of the support frame so that the urine receiving bag is in a taut state and can withstand a certain atmospheric pressure without shrinking. The urine bag 20 is made of PVC or PP bag, and the upper sealing area 22 seals two pipe nozzles 26 with a large interval to respectively connect the urine delivery tube 11 and the negative pressure connection tube 31. Before the sealing operation, a bag of polymer water-absorbing curing agent 23 (not shown) is inserted. The support frame can also be set to 3 feet, corresponding to 3 buckle sleeves evenly distributed on the urine bag 20, but the volume of the urine bag is small after it is expanded, which is not preferred. This solution is suitable for vehicle use.

[0062] Another solution is to drill two round holes at the maximum interval on the mineral water bottle cap, which can be hermetically fitted with the urine delivery pipe 11 and the negative pressure connection pipe 31 respectively, and insert them; find an empty mineral water bottle, put a pack of polymer absorbent curing agent 23 in it, and cover the above-mentioned bottle cap.

[0063] When the cost is acceptable, a splash-proof net 15 can also be added to the portable female urinal, and the structure is the same as that of the nursing type, so it will not be described again.

[0064] This product can also be applied to special practitioners such as high-speed rail and subway drivers, fighter pilots, high-altitude workers, surgeons, cyclists, and marathon runners.

[0065] To solve the contradiction of a serious shortage of public toilets, especially female toilets (more than 90% of the toilet use needs are for urination), such as Figure 10 , a shared urine collection cabinet machine is specially launched. On the upper panel of the urine collection cabinet machine body 50, several urine absorption interfaces 51 are arranged, and then through the inhalation solenoid valve 52 and are converged to the liquid collection pipe 54 through each manifold 53 and connected to the urine collection container 20; the other end of the top of the urine collection container 20 is connected to the negative pressure generator 30 through a second connection pipe, which is called the negative pressure connection pipe 31 in the embodiment. In fact, there are simpler solutions, such as setting a rubber plug at the urine absorption interface 51, pulling it out when in use and plugging it back after use; using a manual valve, manually opening and closing, etc. However, since this urine collection cabinet machine is for shared use, there is a great uncertainty whether the user can consciously reset the device. Therefore, using solenoid valves and automatic control can provide greater guarantee and can be automatically closed after use.

[0066] The urine collection container 20 is placed at the lower part of the urine collection cabinet machine body 50, which is a large-volume tank. Its bottom discharge port is led to the outside of the machine body through a pipeline via the drain solenoid valve 55 to form a drain port 56; a flushing port is arranged at the top of the urine collection container 20, and is led to the outside of the machine body through a pipeline via the liquid inlet solenoid valve 57 to form a liquid inlet port 58.

[0067] The inhalation solenoid valve 52, the drain solenoid valve 55, the liquid inlet solenoid valve 57, the negative pressure generator 30, etc. are all coordinated and controlled by the preset program of the single-chip microcomputer built in the control board 59 in combination with the sensor signals and the manual switch; Figure 11 For Figure 10In the enlarged view of the middle A, several sealing rubber rings 511 are arranged in the hole of the urine absorption interface 51 to match the end of the urine delivery tube 11; during the urine collection operation, the end of the urine delivery tube 11 is inserted into the inner hole of the interface 51, and is covered by the sealing rubber ring 511, so that it will not fall off easily and is sealed; then the corresponding switch (not shown) is pressed, and under the control of the control board 59, the suction solenoid valve 52 is opened, and the negative pressure generator 30 works. Under the action of negative pressure, urine enters the bottom of the interface 51 from the urine delivery tube 11, and then is collected by the opened suction solenoid valve 52 through the manifold 53 to the liquid collecting pipe 54 to connect to the urine receiving container 20; after urination, the switch is pressed, and under the control of the control board 59, the negative pressure generator 30 stops working and the suction solenoid valve 52 is closed; if there is no manual operation, the control board 59 automatically closes the suction solenoid valve 52 after the set time is reached; if there are several urine collection operations at the same time, the negative pressure generator 30 will not stop working until the last one is completed. The negative pressure generator 30 uses a long-life vacuum pump, and the air inlet or exhaust port of the negative pressure generator 30 is also subjected to deodorization treatment (not shown).

[0068] The supporting urinal 10 (for men and women) and the urine delivery tube 11 can be made into a disposable component. If the material of the urine delivery tube 11 is strong enough, it can be directly inserted into the urine absorption interface 51. After use, the urine delivery tube can be pulled out from the interface 51 and discarded. This is the preferred solution of this embodiment with the lowest cost. However, in special cases, such as the material of the urine delivery tube 11 is not strong enough, the weather conditions are limited, etc., a nozzle can be added to the end of the urine delivery tube 11, and the nozzle is airtightly matched with the inner hole of the urine absorption interface.

[0069] When the amount of urine in the urine receiving container 20 reaches the set value, the sensor (not shown) transmits a signal to the control board 59 to control the discharge solenoid valve 55 to open, and the urine is discharged through the discharge port 56 by its own gravity; the urine can be directly connected to the sewer through the discharge port 56 to be discharged, or it can be discharged to the receiving container for recycling; the common properties of the urine collection cabinet make the urine storage and circulation volume in the urine container 20 relatively large. In order to avoid urine accumulation and residue, a flushing device is added, which can not only dilute the urine, but also help the urine to be discharged by the flushing water pressure; when the urine is about to be discharged, the control board 59 controls the liquid inlet solenoid valve 57 to open, and the tap water with its own pressure in the tap water pipe connected to the liquid inlet 58 enters the flushing port at the top of the urine receiving container 20 to flush the residual urine in the urine receiving container 20. After the flushing operation is completed, the control board 59 controls the liquid inlet solenoid valve 57 and the liquid discharge solenoid valve 55 to be closed successively, and return to the waiting state.

[0070] If the urine cannot be discharged by gravity due to space limitations, such as a long distance to the sewer, the discharge solenoid valve 55 can be replaced by a water pump to discharge the urine by power.

[0071] This urine collection cabinet machine can also be derived into a simplified version, which is used in some private occasions without toilets. For the simplified version, the inhalation solenoid valve can be replaced by a manual valve, or a rubber plug can be set at the urine absorption interface 51; the drain solenoid valve and the liquid inlet solenoid valve can also be replaced by manual valves to reduce costs. The simplified version is small and compact, can be placed under the washbasin without occupying space, and can be installed as long as there are upper and lower water conditions, bringing convenience for urination.

[0072] This urine collection cabinet machine can be placed in commercial pedestrian streets, tourist attractions, large gatherings and other places to meet the sudden increase in the urination needs of the crowd, and can be used as an effective supplement to public toilets; the simplified version can be applied to small studios, convenience stores, small stalls and other places.

[0073] As described above, it is only the implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that are thought of without creative work should be covered within the protection scope of the present utility model; unless otherwise clearly stated, any element, action or instruction used in this article should not be construed as critical or necessary.
