Medical personnel need clean both hands and apparatus after changing dressings, but both hands probably all are the filth this moment, in order to avoid polluting tap 43, in the optimization scheme, upper hose 2 and downcomer 15 between be equipped with time delay valve 13, its effect does, after the patient leaves after a period of time after standing up, the water tank begins automatic the draining, medical personnel need not to open tap's operation, just can obtain rivers, make the clearance work of outpatient service change dressings more convenient. As shown in fig. 2, the delay valve 13 includes a cylinder 22 and a linkage valve 20, and the linkage valve 20 is located on the downcomer 15 and controls the opening and closing of the downcomer 15. An upper piston 24 and a lower piston 26 are arranged in the cylinder body 22, the upper piston 24 is connected with a linkage valve 20 through a connecting rod 21, when the linkage valve 20 ascends, a waterway of a downcomer 15 is opened, and when the linkage valve 20 descends, the waterway is closed, and the linkage valve 20 is concretely the prior art, the internal structure is not described in detail, the upper piston 24 is connected with the lower piston 26 through the spring 25, the upper piston 24 and the lower piston 26 divide the cylinder 22 into an upper cavity, a middle cavity and a lower cavity together, the upper piston 24 and the lower piston 26 are respectively provided with a vertical pore 23, two adjacent cavities are connected through the vertical fine holes 23, a water inlet 27 and a water outlet 29 are respectively arranged on the lower cavity and the middle cavity, check valves 28 are respectively arranged at the positions of the water inlet 27 and the water outlet 29, the check valve 28 at the position of the water inlet 27 can only enable water to flow into the cylinder body 22 in a one-way mode, and the check valve 28 at the position of the water outlet 29 can only enable the water in the cylinder body 22 to flow out in a one-way mode. The one-way valve 28 at the water inlet 27 is connected with the upper water pipe 2 through a first water pipe, wherein the connection position is positioned between the manual valve 1 and the water turbine 11, the one-way valve 28 at the water outlet 29 is connected with the lower water pipe 15 through a second water pipe, and the connection position is positioned between the water tank 12 and the linkage valve 20.
The working principle of the delay valve 13 is as follows: in a natural state, the water pressure in the water feeding pipe 2 at the delay valve 13 is the same as that in the water discharging pipe 15, when the manual valve 1 is opened, the water pressure in the water feeding pipe 2 is increased, the water rapidly flows into the lower cavity of the cylinder 22 through the water inlet 27 of the cylinder 22 of the delay valve 13, the lower piston 26 is jacked upwards, the water in the middle cavity is discharged into the water feeding pipe 2 through the water outlet 29, and the spring 25 is compressed; after the manual valve 1 is closed, the water pressure at each position is restored to be balanced, the upper piston 24 is pushed upwards under the action of the spring 25, the lower piston 26 is pushed downwards, water in the upper cavity and the lower cavity respectively flows into the middle cavity through the vertical fine holes 23, so that the upper piston 26 and the lower piston 26 respectively and slowly move upwards and downwards, the upper piston 24 pushes the linkage valve 20 through the connecting rod 21 after a period of time, the linkage valve 20 is opened, and the water in the water tank 12 starts to be cleaned through the sewer pipe 15; the upper and lower pistons 26 then slowly fall by the action of gravity, and after a period of time the position of the upper piston 24 returns to its original position and the linked valve 20 closes.
The operation flow is as follows: sit on supporting mechanism during the use, push down supporting mechanism through self gravity, pull up the counter weight structure through chain 5 simultaneously, the effect through the counter weight structure can play the effect of energy storage, can play certain power effect when the patient stands through the action of gravity of heavy object 14 promptly, the effect through heavy object 14 also can slow down the speed of whereabouts when the patient sits to a certain extent simultaneously, the effect through accelerating gear 7 and speed limit fan speed limit 6 can prescribe a limit to the speed of whereabouts after sitting down the patient in the certain extent. The patient is relatively less to supporting mechanism's effort when just sitting by the posture of standing, and the human effort to supporting mechanism of whereabouts in-process crescent, and the whereabouts in-process passes through chain 5 pulling counter weight structure, and along with the pulling in-process, the pole at heavy object 14 place is gradually become the level by vertical gradually to counter weight structure is to the pulling force crescent of chain 5, suits with the change of human effort to supporting mechanism at this in-process, thereby can have better comfort.
Open manual valve 1 when the patient need stand, tap water is followed water pipe 2 internal flows into water tank 12, and drive hydraulic turbine 11 simultaneously is rotatory, is the power supply through the hydraulic turbine, drives sprocket 8 rotatory, mentions supporting mechanism through chain 5 to can help the patient to stand. Tap water company is in order to send the running water to higher floor, and the running water often has great pressure, and reduction gear set 10 can also enlarge strength through the gear train drive ratio in addition, can regard unnecessary water pressure as power drive device operation through this device, and the help patient stands, need not power consumptive to have energy-concerving and environment-protective characteristics, this device also can normal operating when having a power failure simultaneously. Besides, when the water tank 12 is full of water, the device can be driven to operate by the motor 9.
In a natural state, the water pressure of the water feeding pipe 2 and the water discharging pipe 15 at the position of the delay valve 13 is the same, the water pressure in each cavity in the sub-valve is also the same, under the combined action of gravity and the elastic force of the spring 31, the valve core 42 is positioned at the bottom of the cavity in the shell 40, at the moment, the water inlet 36 and the water outlet 37 of the first valve 38 are positioned at the middle cavity, the first valve 38 is in an open state, the piston 34 under the second valve 39 is positioned at the water inlet 36 and the water outlet 37 to block the water inlet 36 and the water outlet 37, the second valve 39 is in a closed state, and the whole delay valve 13 is in a. When the manual valve 1 is opened, the water pressure of the upper water pipe 2 is increased, so that the water pressure in the lower cavity of the sub-valve is increased, the valve core 42 is pushed upwards under the action of the water pressure, the water in the upper cavity is discharged into the lower water pipe 15 through the water outlet 30, the lower piston 34 of the first valve 38 blocks the water inlet 36 and the water outlet 37, the first valve 38 is closed, after the valve core 42 of the second valve 39 is moved upwards, the water inlet 36 and the water outlet 37 are positioned in the lower cavity, the second valve 39 is in an open state, and the whole delay valve 13 is in a closed state; the third spring 31 is elastically reset to cause the valve core 42 to fall, water in the middle cavity slowly enters the upper cavity through the vertical pore 41, and the space in the upper cavity is gradually increased, so that the valve core 42 can slowly fall, the first valve 38 has a larger diameter of the vertical pore 41, so that the first valve 42 can fall earlier after a period of time, after the first valve 42 falls, the first valve 38 is opened, and the second valve 39 is also opened, so that the delay valve 13 is opened to start flushing; after a period of time, the valve core 42 of the second valve 39 falls down, the second valve 39 is closed, and toilet flushing is finished.
It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
