Description

[Technical field]

[0001] The invention relates to the technical field of medical nursing equipment, in particular to a water isolating device of a nursing machine. [Background technology]

[0002] The number of bedridden patients who cannot take care of themselves due to cardiovascular and cerebrovascular diseases is increasing year by year, which has brought great pressure to families and society. Since patients cannot take care of themselves, they need the assistance of caregivers, and the uncertainty of patients' defecation time increases the workload of caregivers, and causes great pain and burden to patients physically and especially mentally. Therefore, medical institutions and patients' families often equip patients with defecation and urination care machines.

[0003] The nursing machine in the prior art mainly includes a wearable toilet collector and a main unit. The toilet collector and the main unit are usually connected by a water supply pipeline, a sewage suction pipeline, etc. The toilet collector is provided with a toilet bowl, and the main unit is usually provided with a negative pressure source that provides power for suction and discharge of sewage, and a sewage bucket assembly for accommodating sewage. The negative pressure source includes an air inlet, an exhaust outlet, a motor, and an impeller driven by the motor to rotate. The motor drives the impeller to rotate to generate suction force. The process of sucking human excrement is roughly as follows: the human body defecates in the toilet bowl of the toilet collector, the nozzle of the toilet collector flushes the human body and excrement, the negative pressure source performs suction, and the excrement and sewage in the toilet bowl are sucked into the sewage bucket assembly through the sewage suction pipeline along with the suction airflow, and the suction airflow further flows from the sewage bucket assembly through the pipeline between the sewage bucket assembly and the water isolation device into the inner cavity of the water isolation device, and further flows from the water isolation device through the pipeline between the negative pressure source and the water isolation device into the negative pressure source, and then is discharged from the exhaust outlet of the negative pressure source.

[0004] Since the aforementioned airflow passing through the water-isolating device will inevitably carry more water vapor and a small amount of foreign matter (the foreign matter originates from human excrement, and in the whole process of the excrement being sucked away along with the airflow, the airflow and water vapor flowing to the water-isolating device will inevitably be slightly mixed with a small amount of foreign matter separated from the excrement, which also causes the airflow to be smelly. In order to deodorize, the nursing machine in the prior art generally has a deodorization unit at the exhaust outlet of the negative pressure source, such as a negative ion deodorization unit or a catalyst deodorization unit and other commonly used deodorization mechanisms), liquid (water and foreign matter) will gradually accumulate in the water-isolating device. As the water level of the water accumulated in the water-isolating device rises, when the negative pressure source is sucked normally, the water accumulated in the water-isolating device may be directly sucked into the negative pressure source and discharged, which will cause the water inlet of the negative pressure source to be damaged, and cause the main unit to discharge water and mess up the surrounding environment.

[0005] To this end, CN203829212 discloses a water-isolating device of the prior art: when the water level of the water accumulated in the water-isolating device reaches a certain preset height, the float provided in the water-isolating device floats up and is close to the air outlet pipe. When the negative pressure source is working, the float can be adsorbed and the air outlet pipe of the water-isolating device is blocked, thereby preventing the negative pressure source from absorbing the water accumulated in the water-isolating device. The air inlet pipe corresponds to the water storage cup above and below and is located above the water storage chamber. The foreign matter accumulated in the water storage cup is easy to accumulate water and foreign matter. The foreign matter accumulated in the water storage cup is easy to diffuse without hindrance along with the accumulated water, so that the foreign matter is easy to diffuse to the side where the float is located, resulting in more foreign matter attached to the float, which will greatly affect the normal floating of the float and the blocking of the air outlet pipe.

[0071] The upper cover 4 also includes a baffle 42, which extends downward into the inner cavity of the base 6. The baffle 42 extends downward beyond the air inlet port 40 and the air outlet port 41. The baffle 42 is located between the air inlet port 40 and the air outlet port 41. The baffle 42 blocks the side of the air inlet port 40 close to the air outlet port 41, so that the airflow of the air inlet port 40 needs to bypass the baffle 42 and flow to the air outlet port 41, which is conducive to more sewage, foreign matter, etc. carried in the airflow falling into the inner cavity of the base 6. The upper cover 4 further includes a bottom plate 43, an annular retaining rib protruding downward from the bottom plate 43, the air inlet port 40 and the air outlet port 41 respectively penetrate the bottom plate 43, the annular retaining rib surrounds the outer periphery of the air inlet port 40 and the air outlet port 41, the annular retaining rib includes a first rib segment 440 and a second rib segment 441 spaced apart, the air inlet port 40 and the air outlet port 41 are located between the first rib segment 440 and the second rib segment 441, the baffle 42 extends downward from the bottom plate 43, one end 420 of the opposite ends of the baffle 42 is integrally connected to the first rib segment 440, and the other end 421 of the opposite ends is integrally connected to the second rib segment 441. The first rib segment 440 and the second rib segment 441 are respectively straight. The annular retaining rib also includes a third rib segment 442 and a fourth rib segment 443 spaced apart, the third rib segment 442 and the fourth rib segment 443 are arc-shaped, the retaining plate 42 is located between the third rib segment 442 and the fourth rib segment 443, the third rib segment 442 is connected between the first rib segment 440 and the second rib segment 441, the fourth rib segment 443 is connected between the first rib segment 440 and the second rib segment 441, the third rib segment 442 has a hook 445 extending in a direction away from the fourth rib segment 443, the annular retaining rib matches the shape of the upper port 66 of the base 6 and is installed in the upper port 66 of the base 6, the base 6 is provided with a positioning port 67, and the hook 445 is embedded in the positioning port 67. The outer periphery of the annular retaining rib is sealed with glue and the base 6, so that the gap between the bottom plate 43 and the base 6 is sealed to ensure the sealing between the bottom plate 43 and the base 6. The positioning port 67 is a through hole, and the hook 445 is sealed with glue and the positioning port 67. The upper cover 4 also includes a cross 45, which is located in the air inlet port 40. A sponge block can be set on the upper side of the cross 45 in the air inlet port 40 to absorb water. The sponge block is cylindrical and matches the shape of the air inlet port 40. The sponge can be fixed in the air inlet port 40 by glue.

[0072] The base 6 is provided with a first screw hole 660 located at the periphery of the annular retaining rib, and the water-blocking device also includes a first screw 520 for fixing the upper cover 4 and the base 6. The first screw 520 is threadedly connected to the first screw hole 660. The first screw hole 660 and the positioning hole 67 are located at the periphery of the annular retaining rib and at opposite sides of the upper end 66 of the base 6. With such an arrangement, as long as only one screw, the first screw 520, is locked, the upper cover 4 and the base 6 can be relatively balanced in relative positioning on opposite sides (through the cooperation of the first screw 520 and the first screw hole 660 combined with the cooperation of the hook 445 on the other side and the positioning hole 67), and the upper cover 4 and the base 6 can be positioned on opposite sides respectively, which is also convenient for the subsequent locking of other screws and optimizes the screw locking process.

[0073] When installing the upper cover 4 on the base 6, first install the side where the third rib segment 442 is located into the upper port 66 of the base 6 and embed the hook 445 into the positioning port 67, so that the side where the third rib segment 442 is located is roughly positioned relative to the base 6, and then install the side where the fourth rib segment 443 is located into the upper port 66 of the base 6, and then pass the screws (the first screw 520, the second screw 521, the third screw 522) through the ears (the first ear 430, the second ear 431, the third ear 432) on the outer periphery of the bottom plate 43 and threadedly connect them to the screw holes (the first screw hole 660, the second screw hole 661, the third screw hole 662) of the base 6. Since the first screw 520 and the first screw hole 660 are both located on the opposite sides of the upper port 66 from the positioning port 67, after first locking the first screw 520, the upper cover 4 can be initially and balancedly positioned on the upper port 66, and then the other two screws are locked to speed up the installation.

[0075] The nursing machine host 10 also includes an air inlet pipeline for connecting the sewage bucket assembly 3 with the air inlet port 40 of the water isolation device, and an air outlet pipeline for connecting the negative pressure source 20 with the air outlet port 41 of the water isolation device. The air inlet pipeline includes an air inlet hose 54 (only a part of the air inlet hose 54 is schematically shown in the accompanying drawings, and in fact the air inlet hose 54 should be a longer curved shape), and a first connecting pipeline 55; one end 540 of the opposite ends of the air inlet hose 54 is connected to the air inlet port 40 and sealed with glue, and the other end of the opposite ends of the air inlet hose 54 is connected to one end 550 of the opposite ends of the first connecting pipeline 55 and sealed with glue, the first connecting pipeline 55 includes a second interface portion 22, and the air outlet pipeline includes an air outlet hose 56 (only a part of the air outlet hose 56 is schematically shown in the accompanying drawings, and in fact the air outlet hose 56 should be a longer curved shape), one end 560 of the opposite ends of the air outlet hose 56 is connected to the air outlet port 41, and the other end of the opposite ends of the air outlet hose 56 is connected to the air inlet 200 of the negative pressure source 20. The toilet collection tank 11 is provided with a toilet bowl 110, and the negative pressure source 20 also includes an exhaust outlet (not shown, usually arranged at the bottom of the negative pressure source 20), a motor (not shown, arranged inside the negative pressure source 20) and an impeller driven to rotate by the motor (not shown, arranged inside the negative pressure source 20), the motor drives the impeller to rotate to generate a suction force to drive the airflow to enter the negative pressure source 20 from the air inlet 200 and discharge the negative pressure source 20 from the exhaust outlet.

[0076] The water-isolating device further includes a first conductive probe 90 and a second conductive probe 91 respectively exposed in the water storage chamber 600, a first conductive line (not shown) connected to the first conductive probe 90, and a second conductive line (not shown) connected to the second conductive probe 91. The first conductive probe 90 and the second conductive probe 91 are at different heights. When the liquid collected in the water storage chamber 600 submerges at least a portion of the first conductive probe 90 and at least a portion of the second conductive probe 91, the first conductive line is electrically connected to the first conductive probe 90, the liquid collected in the water storage chamber 600, and the second conductive probe 91 in sequence. The second conductive circuit, at this time, indicates that the liquid collected in the water storage chamber 600 has reached a certain height. At this time, the control system can control the nursing machine to issue an alarm to remind the user that the liquid collected in the water storage chamber 600 exceeds the warning line and the water storage chamber 600 needs to be emptied; specifically, the first conductive circuit and the second conductive circuit can be wires, which are respectively connected to the control system of the nursing machine. Once the first conductive circuit and the second conductive circuit are electrically connected by the first conductive probe 90, the liquid collected in the water storage chamber 600, and the second conductive probe 91, they can form a conductive circuit with the control system and trigger the control system to issue an alarm. The first conductive probe 90 and the second conductive probe 91 are screws, respectively locked in the water storage cup 60, and the front end of the first conductive probe 90 and the front end of the second conductive probe 91 are respectively inserted into the water storage chamber 600, so as to make it easier to contact the liquid collected in the water storage chamber 600. The first conductive probe 90 and the second conductive probe 91 are arranged horizontally.

[0077] The present invention mainly realizes liquid level detection through the first conductive probe 90 and the second conductive probe 91. The height of the second conductive probe 91, the first conductive probe 90 and the second conductive probe 91 is only a little higher than the lower end of the float accommodating chamber 610 (less than 2 mm). In fact, the float 50 is a supplementary preparatory mechanical safety measure, which forms a double insurance with the liquid level detection of the conductive probe. If the liquid level detection of the first conductive probe 90 and the second conductive probe 91 is not invalid and the user promptly empties the water storage chamber 600 after receiving the liquid level alarm, the float 50 can be used to play a corresponding blocking role. When the liquid level detection of the first conductive probe 90 and the second conductive probe 91 fails, the float 50 can block the air outlet port 41 after the liquid level reaches a certain height, thereby playing its role in water isolation and overflow prevention.

[0078] The water-proof device also includes a vent 92 connected to the inner cavity of the base 6. The base 6 is fixed to the upper cover 4. The vent 92 passes through the bottom plate 43 respectively. The baffle 42 is located between the vent 92 and the air outlet port 41, and the vent 92 is located between the air inlet port 40 and the baffle 42. The nursing machine host 10 also includes an air duct (not shown) and an air pressure detection unit (not shown) for detecting the air pressure in the inner cavity of the base 6. One of the opposite ends of the air duct is connected to the vent 92, and the other end of the opposite ends of the air duct is connected to the air pressure detection unit, so that the air pressure in the inner cavity of the base 6 is reflected to the air pressure detection unit. The air pressure detection unit can adopt existing technology as long as it can detect air pressure, such as pressure detection equipment for detecting tire air pressure, pressure gauge of air compressor, etc., but the air pressure detection unit does not need to display the air pressure value, and the specific structure of the air pressure detection unit is not repeated. When the sewage suction pipeline between the toilet 11 and the main unit 10 is blocked and the negative pressure source 20 is sucking normally, the air pressure in the inner cavity of the base 6 will be low. It can be set that when the air pressure detection unit detects that the air pressure in the inner cavity of the base 6 is lower than a certain value (indicating that it is very likely due to the blockage of the sewage suction pipeline), the control system can issue a prompt to inform the user to check the sewage suction pipeline.

[0079] The host 10 is also provided with a first interface portion 21, which can be fluidically connected between the sewage suction hose 12 and the sewage bucket assembly 3, and the second interface portion 22 can be fluidically connected between the sewage bucket assembly 3 and the negative pressure source 20. Human excrement is sucked into the sewage bucket assembly 3, and the sewage bucket assembly 3 includes a sewage inlet port portion 30, an airflow outlet port portion 31, and an adapter 32. The adapter 32 includes a first adapter portion 320 docked with the sewage inlet port portion 30 and a second adapter portion 321 docked with the airflow outlet port portion 31. When the adapter 32 is in the first position, the first adapter portion 320 docks with the first interface portion 21 to connect the first interface portion 21 with the sewage inlet port portion 30, and the second adapter portion 321 docks with the second interface portion 22 to connect the sewage inlet port portion 30. The second interface portion 22 is connected to the airflow outflow port portion 31. At this time, the sewage flow passage of the sewage bucket assembly 3 is open, and the nursing machine can normally absorb excrement into the sewage bucket assembly 3; when the adapter device 32 is in the second position, the first adapter portion 320 is disengaged from the first interface portion 21 and blocks the dirt from entering the port portion 30, and the second adapter portion 321 is disengaged from the second interface portion 22 and blocks the airflow outflow port portion 31. At this time, the sewage flow passage of the sewage bucket assembly 3 is blocked, and the nursing machine cannot absorb excrement into the sewage bucket assembly 3. When the adapter 32 of the present invention is in the first position, the sewage bucket assembly 3 is docked with the corresponding interface, and the adapter 32 is in the second position, the aforementioned docking is released, the dirt inlet port 30 and the airflow outlet port 31 are blocked, and the odor, dirt, etc. are effectively isolated from the outside, and it is difficult for the dirt inlet port 30 and the airflow outlet port 31 to be released to the outside, and the user experience is good. The user does not have to worry about the stench of taking out the sewage bucket, and can calmly transport the sewage bucket assembly 3 to dump. In this embodiment, the adapter 32 can be switched between the first position and the second position by moving the adapter 32 forward and backward. Figure 8 , Fig. 9 The transfer device 32 is in the second position, and when the transfer device 32 is in the second position, it is suitable for taking out the sewage bucket assembly 3 to perform emptying operation, etc. The negative pressure source 20 is provided with a motor and an impeller driven to rotate by the motor. The toilet collecting tank 11 is provided with a toilet trough 110.

[0080] The first adapter portion 320 at least partially enters into the dirt inlet port portion 30, and the second adapter portion 321 at least partially enters into the airflow outlet port portion 31. The outer end 3200 of the first adapter portion 320 is provided for docking with the first interface portion 21, and the outer end 3210 of the second adapter portion 321 is provided for docking with the second interface portion 22. When the adapter device 32 is in the second position, the inner end 3201 of the first adapter portion 320 blocks the dirt inlet port portion 30 and the inner end 3211 of the second adapter portion 321 blocks the airflow outlet port portion 31. The blocked dirt inlet port portion 30 is blocked, and the blocked airflow outlet port portion 31 is blocked.

[0081] The first adapter part 320 is tubular, and an inner end 3201 of the first adapter part 320 is provided with a first inclined opening 3202. When the adapter device 32 is in the second position, the tube wall of the inner end 3201 of the first adapter part 320 located below the first inclined opening 3202 blocks dirt from entering the port part 30. The second adapter part 321 is tubular, and an inner end 3211 of the second adapter part 321 is provided with a second inclined opening 3212. When the adapter device 32 is in the second position, the tube wall of the inner end 3211 of the second adapter part 321 located below the second inclined opening 3212 blocks airflow from flowing out of the port part 31.

[0082] The waste inlet port 30 includes a first transverse pipe section 300 sleeved on the first adapter 320 and a first longitudinal pipe section 301 connected to the first transverse pipe section 300. The airflow outlet port 31 includes a second transverse pipe section 310 sleeved on the second adapter 321 and a second longitudinal pipe section 311 connected to the second transverse pipe section 310. When the adapter 32 is in the second position, the inner end 3201 of the first adapter 320 blocks the upper end of the first longitudinal pipe section 301 to achieve blocking of the waste inlet port 30 and the inner end 3211 of the second adapter 321 blocks the upper end of the second longitudinal pipe section 311 to achieve blocking of the airflow outlet port 31. The second longitudinal pipe section 311 is provided with a filter 3110, and the filter 3110 is located upstream of the second adapter 321. The upstream and downstream described in the present invention are defined according to the flow direction of the excrement being sucked and the flow direction of the airflow sucking the excrement.

[0083] The tube wall of the first longitudinal tube section 301 is provided with a notch 3010, and part of the tube wall of the first longitudinal tube section 301 separates the airflow inlet 3111 of the second longitudinal tube section 311 from the notch 3010, which can effectively prevent the excrement from being directly sucked into the airflow inlet 3111 from the notch 3010, and promote the excrement to fall into the bucket more directly. The first longitudinal tube section 301 extends downwardly beyond the second longitudinal tube section 311 by about 5 cm to 15 cm, which is conducive to guiding the excrement to fall into the bucket, and inhibiting the excrement from being sucked into the airflow inlet 3111 of the second longitudinal tube section 311 after coming out of the first longitudinal and transverse tube sections, and promoting the excrement to fall into the bucket more directly.

[0084] The first adapter part 320 is tubular, and the second adapter part 321 is tubular. When the adapter device 32 is in the second position, the inner end 3201 of the first adapter part 320 blocks the upper end of the first longitudinal tube section 301, and the inner end 3211 of the second adapter part 321 blocks the upper end of the second longitudinal tube section 311, thereby blocking dirt from entering the port part 30 and airflow from the port part 31. The first adapter part 320 is a straight tube, and the second adapter part 321 is a straight tube. The inner end tube wall of the first adapter part 320 that blocks the upper end of the first longitudinal tube section 301 generally belongs to the lower half of the tube wall of the first adapter part 320, and the inner end tube wall of the second adapter part 321 that blocks the upper end of the second longitudinal tube section 311 generally belongs to the lower half of the tube wall of the second adapter part 321.

[0085] The first adapter part 320 is also provided with a first sealing ring 3203, and the first sealing ring 3203 is sleeved on the first adapter part 320 to block the gap between the first adapter part 320 and the dirt inlet port part 30. The second adapter part 321 is also provided with a second sealing ring 3213, and the second sealing ring 3213 is sleeved on the second adapter part 321 to block the gap between the second adapter part 321 and the airflow outlet port part 31. The first sealing ring 3203 is located between the inner end and the outer end of the first adapter part 320, and the second sealing ring 3213 is located between the inner end and the outer end of the second adapter part 321. When the adapter device 32 is at any position between the first position and the second position, the first sealing ring 3203 is within the dirt inlet port 30 and the second sealing ring 3213 is within the airflow outflow port 31, so that the adapter 32 is at any position between the first position and the second position, the first sealing ring 3203 can maintain a good state of sealing the gap between the first adapter part 320 and the dirt inlet port 30, and the second sealing ring 3213 can maintain a good state of sealing the gap between the second adapter part 321 and the airflow outflow port 31, and it is always difficult for dirt to flow out of the sewage bucket assembly 3 from the gap between the first adapter part 320 and the dirt inlet port 30, and it is also difficult to flow out of the sewage bucket assembly 3 from the gap between the second adapter part 321 and the airflow outflow port 31.

[0086] The adapter 32 is closer to the dirt inlet port 30 and the airflow outlet port 31 in the second position than in the first position. During the movement of the adapter 32 from the second position to the first position, the first adapter 320 moves outside the dirt inlet port 30 and the second adapter 321 moves outside the airflow outlet port 31. During the movement of the adapter 32 from the first position to the second position, the first adapter 320 retreats into the dirt inlet port 30 and the second adapter 321 retreats into the airflow outlet port 31, so that the adapter 32 is closer to the dirt inlet port 30 and the airflow outlet port 31.

[0087] The adapter 32 also includes an outer frame portion 322 integrally formed with the first adapter portion 320 and the second adapter portion 321. When the adapter 32 is in the first position, the portion of the dirt inlet port portion 30 that enters between the first adapter portion 320 and the outer frame portion 322 is less than the portion of the dirt inlet port portion 30 that enters between the first adapter portion 320 and the outer frame portion 322 when the adapter 32 is in the second position. In short, more dirt enters the port portion 30 in the second position. When the adapter 32 is in the first position, the portion of the airflow outlet port portion 31 that enters between the second adapter portion 321 and the outer frame portion 322 is less than the portion of the airflow outlet port portion 31 that enters between the second adapter portion 321 and the outer frame portion 322 when the adapter 32 is in the second position. In short, more dirt enters the port portion 30 in the second position.

[0088] The outer frame 322 surrounds the first adapter 320 and the second adapter 321, the dirt inlet port 30 is partially inserted between the first adapter 320 and the outer frame 322, and the airflow outlet port 31 is partially inserted between the second adapter 321 and the outer frame 322. The outer frame 322 is provided with two cantilever arms 3220 for locking the adapter 32 in the first position. The two cantilever arms 3220 are located on the left and right sides of the outer frame 322. The two cantilever arms 3220 are respectively provided with barbs 3221 and inclined pressing portions 3222. The host 10 is also provided with a docking recess 13. When the pressing portion 3222 is pressed to unlock, the pressing force also produces the effect of pushing the adapter 32 out of the docking recess 13 due to the inclination of the pressing portion 3222. The dirt inlet port 30, the outer frame 322, and the airflow outlet port 31 are respectively provided with transversely extending guide ribs 323. The first interface portion 21 and the second interface portion 22 are respectively partially located in the docking recess 13. When the adapter 32 is in the first position, the outer frame portion 322 can be unlocked and locked to and at least partially accommodated in the docking recess 13. The docking recess 13 has locking grooves 130 on both sides. When the adapter 32 is in the first position, the barbs 3221 of the cantilever arm 3220 are embedded in the grooves 130 to lock the adapter 32 in the docking recess 13.

[0089] The host 10 is also provided with a button 14, which is pressed when the adapter 32 is in the first position to indicate that the adapter 32 is installed in place. The button 14 can rebound after being released from being pressed, and the button 14 protrudes into the docking recess 13. When the adapter 32 is in the first position, its outer frame 322 presses the button 14.

[0090] The first adapter part 320 is arranged in parallel with the second adapter part 321, and the first adapter part 320 is arranged in parallel with the second adapter part 321. The waste inlet port part 30 is arranged in parallel with the airflow outlet port part 31, and the waste inlet port part 30 and the airflow outlet port part 31 are integrally formed. The sewage bucket assembly 3 also includes a barrel body 37, an upper cover 33 arranged on the upper part of the barrel body 37, a handle 34 arranged on the upper cover 33 for moving the sewage bucket assembly 3, a sewage outlet 35 opened on the upper cover 33, and a barrel cover 36 detachably installed on the upper cover 33 and blocking the sewage outlet 35. The waste inlet port part 30, the airflow outlet port part 31 and the barrel cover 36 are integrally formed, and the waste inlet port part 30, the airflow outlet port part 31, the barrel cover 36, and the adapter 32 constitute a barrel cover assembly, and the waste inlet port part 30 and the airflow outlet port part 31 respectively penetrate the barrel cover 36. The barrel cover 36 is screwed and installed on the upper cover 33 .

[0091] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
