Embodiment Construction

[0010] The mechanism uses tap water as power, and is designed as a special hydraulic transmission mechanism, which utilizes the area difference between the cavity of the piston rod 707 and the piston cavity to achieve rapid retraction of the piston rod even if the flow rate in the cavity of the piston rod is small. To achieve the purpose of quickly opening the drop door. The process is: the hydraulic water cylinder 709 is transformed from a listed pneumatic cylinder, the diameter of the piston rod 707 is close to the inner diameter of the cylinder barrel, the bottom of the piston chamber of the hydraulic water cylinder 709 is made with a large-diameter pipe thread, connected to the tee 703, and when the piston rod chamber enters the small Flow rate of tap water (with the transformed small diameter "electromagnetic, gas pilot control reversing water valve" 306 water supply, it has anti-corrosion capability.), the piston chamber is additionally connected with a large diameter ele...

Abstract

The invention discloses a hydraulic-water-cylinder piston rod rapid-retracting mechanism for an automatic-defecating-assisting lying toilet bowl. The hydraulic-water-cylinder piston rod rapid-retracting mechanism serves patients needing to go to a toilet with a lying gesture on a bed, wherein when feces and urine of patients lying in bed are discharged randomly, a monitoring mechanism can be triggered in time to obtain signals, a signal driving mechanism rapidly opens a fences falling door, and the patients enter the lying-gesture toileting mode. For furthest reducing pollution of urinating and defecating on bedding, after the mechanism receives an instruction for opening the fences falling door, if a conventional hydraulic pressure design is used, movement of the mechanism is slow, and the rapid requirement cannot be met. A hydraulic water cylinder in the mechanism is reconstructed through a marketed air cylinder, wherein the diameter of a piston rod of the hydraulic water cylinder isclose to the inner diameter of a cylinder barrel, and when a large-diameter electromagnetic water valve is additionally connected in a lower cavity of the water cylinder, the hydraulic-water-cylinderpiston rod can be rapidly retracted, and therefore it is achieved that the fences falling door is rapidly opened. The air cylinder is changed into a tap water cylinder, and a pneumatic reversing valve is changed into an electromagnetic pneumatic control water valve. Multiple small-diameter electromagnetic water valve factors are further omitted after replacement, and namely, small discrete valvesare merged into a reversing valve.

Description

technical field [0001] The invention belongs to a hydraulic water cylinder mechanism for opening a toilet drop door for an automatic defecation-assist recliner, in particular to a hydraulic water cylinder with the function of rapidly retracting a piston rod and a mechanism composed of supporting parts thereof. Background technique [0002] Among the existing hospital beds with falling doors, there is one with the fastest door opening speed, about 5 seconds. The opening time of other similar beds is two to three times that. Of course, under the premise of getting the patient's cooperation, the patient can endure the defecation door after expressing his desire to defecate, and a faster speed is not necessary. If it is faster, it must be supported by a sudden increase in motor power. But if there is no need to express and pull or can not carry out the control of a little longer, then the speed of opening the toilet door must be greatly accelerated. In the existing hospital b...
