Abstract

A scanning type bedpan flushing mechanism, the flushing main body is a semi-circular tubular hydraulic water cylinder type structure. The nozzle walking groove with the length of a half inner ring is arranged on the outer shape of the hydraulic cylinder, and the half ring section is also used as a semi-circular arc hollow piston running guide pipe of the semi-circular tubular hydraulic cylinder. When the semicircular tubular hydraulic water cylinder is filled with water, the pressure water overcomes the elasticity of the tension spring, pushes the semicircular tubular piston to move along the guide semicircular ring, and flushes water to the wall of the bedpan through the nozzle at the foremost end of the semicircular tubular piston, thereby forming scanning type semicircular arc flushing. When the water supply is stopped, the semi-circular tubular piston retracts under the pulling of the tension spring in the semi-circular tubular piston, and simultaneously extrudes the residual water in the hollow piston to the wall of the toilet bowl through the nozzle at the foremost end of the semi-circular tubular piston. A pair of the mechanisms are symmetrically stacked by the traveling grooves to form a full circle scanning type flushing mechanism, and the action of the scanning type flushing mechanism is like that of locking a bicycle. The flushing quantity required by the toilet bowl for achieving the flushing cleanness is much less than that of a toilet bowl.

Description

Scanning type bedpan flushing mechanism

Technical Field

The invention belongs to a scanning type flushing mechanism, in particular to a toilet flushing mechanism which is used for saving more water than the prior toilet when the flushing quantity of the toilet each time is required, for example, a water-saving flushing mechanism used on a bedpan which automatically assists the defecation.

Background

In the closest art of the related urinal flushing with water saving effect, the design of vacuum type flushing is required. However, the air conditioner has high operation and maintenance cost, high noise and large and expensive mechanism, so that although water is saved, the air conditioner is generally only used in specific places such as airplanes (the mixture can be sucked away by utilizing the difference between the air pressure inside and outside the airplane when the airplane flies in the air, and a vacuum pump is not required to be started), high-speed rails and the like, and the water saving requirement is high. Obviously, the design is not suitable for general sites. How to design the toilet bowl so as to achieve the purpose that the water quantity of the toilet bowl at each time needs to be more water-saving than that of the existing toilet bowl?

Disclosure of Invention

The technical problem to be solved by the invention is as follows: because the final treatment of the mixture of the excrement and the water of the bed pan with the automatic defecation assisting function adopts the form of manually pouring a 'closestool', the natural 'closestool' cannot be too heavy, and the problem that the water is saved when the bed pan is flushed by water compared with a closestool is solved. The measures are as follows: the flushing mechanism of the bed pan is preferably designed into a specially designed semicircular-ring-shaped hydraulic water cylinder type, the flushing mechanism is arranged at the upper edge of the bed pan in pairs and symmetrically in a stacked mode, the electromagnetic water valve controlled by a PLC supplies water to the flushing mechanism, under the action of water pressure during water supply, the semicircular-arc-shaped hollow piston with the sealing head moves in an arc shape towards the outside of the semicircular-ring-shaped hydraulic water cylinder on one side and sprays water outwards through the water spraying outlet groove from the nozzle positioned at the end of the semicircular-arc-shaped hollow piston on the other side, and the flushing mechanisms are symmetrically arranged and respectively arranged on the flushing half sides and together to flush the bed pan in a 360-degree scanning mode. The flushing mode not only achieves no dead angle, but also better utilizes the pressure of tap water during flushing, and compared with the indirect water supply of a water tank with small height difference relative to a urinal of a toilet, the flushing mode has much larger invariable flushing pressure, has better effect than the flushing effect of the toilet, can reduce the flushing time, naturally can reduce the water consumption, and is simple in principle. Water conservation is particularly important for the limited (artificially dumped, naturally limited) chamber pot capacity of the bed pan.

Has the advantages that: the flushing device can effectively flush the round bedpan in a water-saving way, and meets the flushing requirement of the bedpan with the automatic defecation assisting function. The design of the vacuum toilet for the bed pan with the automatic defecation assisting function is avoided, and the defects of the vacuum toilet are avoided. Thereby greatly improving the flushing environment. The bed pan with the automatic defecation assisting function has the following characteristics: because the pipe diameter of the sewage discharge pipe of the toilet bowl is not limited to be smaller, the pipe from the toilet bowl to the urinal can be designed to be much larger, so that excrement basically falls into the pipe, the excrement is rarely polluted on the wall of the toilet bowl, the flushing water is mainly used for flushing urine on the wall of the toilet bowl, the flushing difficulty is greatly reduced, and the water-saving toilet bowl is also beneficial to water saving. The action of the bicycle lock is like that of locking the bicycle. The flushing quantity required by the toilet bowl for achieving the flushing cleanness is much less than that of a toilet bowl. Because of this location, some internal leakage between the circular cylinder and the semi-circular hollow piston is of little consequence. Therefore, the shape of the arc cylinder barrel and the semi-arc hollow piston is not a perfect circle because the arc cylinder barrel and the semi-arc hollow piston are bent by the pipe bending machine, the stress is equivalent by the same process, only the circular hollow piston is bent by the die with different diameters, and the shape of the circular hollow cylinder barrel and the semi-arc hollow piston is basically matched, so that the requirements of form and position tolerance of the circular hollow cylinder barrel and the semi-arc hollow piston can be met. The process which is simpler in manufacturing can be adopted, and the cost is reduced. Because the invention and one of its served objects: the bedpan mechanism for automatically assisting defecation closely relates to the following service objects, namely the bedpan mechanism for automatically assisting defecation obtains the beneficial effects: the patient gets the automatic and fully pollution-controllable bed-lying toilet service, and the pollution caused by defecation is little. The bed toilet has unprecedented sanitary and comfortable experience; patient cooperation and attendance of nursing personnel are not needed, the operation is safe and stable, and the total nursing cost is the lowest in various modes; the diaper is thoroughly thrown away, the nursing environment is greatly improved, the nursing labor intensity is greatly reduced, the economic and mental burdens of children are reduced, the harmony of nursing is increased, and the physical and mental burdens of family members are released; the bedsore is effectively reduced, or the patient with the bedsore obtains the best treatment environment; the odor in the room is effectively restrained, and the air quality in the room is greatly improved. The quilt uncovering operation is greatly reduced, so that the cold, illness and cramping are reduced; the clean and graceful treatment mode maintains the dignity of the patient and enables the family members of the patient to be greatly soothed; effectively preventing the old people who abuse in extreme situations from happening and indirectly prolonging the service life of the patient; humanitarian and humanistic care are brought out better. The invention has great significance to the bed pan and is a basic part thereof. The invention is also used for a novel scanning type flushing toilet bowl, and achieves good effect.

Detailed Description

Can achieve the effect of saving more water than the prior toilet bowl and the like in each time of flushing water. The measures are as follows: the toilet flushing mechanism is preferably a specially designed scanning type 18-type toilet flushing mechanism, which is symmetrically stacked at the upper edge of the toilet and is supplied with water by an electromagnetic water valve controlled by a PLC (programmable logic controller), when water is supplied, under the action of water pressure, the semicircular arc-shaped hollow piston 183 with the sealing head moves towards the outside of the semicircular annular tubular hydraulic water cylinder in an arc way, and sprays water outwards from the water spraying hole 185 of the water spraying nozzle positioned at the end of the semicircular arc-shaped hollow piston through the nozzle outlet groove 187 with half the length of the inner ring, and the symmetrically arranged pair of scanning type toilet flushing mechanisms 18 are added at each flushing half edge to flush the toilet 3 in a 360-degree scanning type. The flushing mode not only achieves no dead angle, but also better utilizes the pressure of tap water during flushing, and compared with the indirect water supply of a water tank with small height difference relative to a urinal of a toilet, the flushing mode has much larger invariable flushing pressure, the effect is better than that of the toilet, the flushing time can be reduced with good effect, and the water consumption can be reduced naturally. Water conservation is particularly important for the limited (manual dumping, naturally limited) volume of the bed pan in the urinal (the bowl has to discharge the mixed waste into the urinal several times during a dumping cycle). The bed pan with the automatic defecation assisting function has the following characteristics: because the pipe diameter of the sewage discharge pipe of the toilet bowl is not limited to be smaller, the pipe from the toilet bowl to the urinal can be designed to be much larger, so that excrement basically falls into the pipe, the wall of the toilet bowl is very small in contamination, the flushing water is mainly used for flushing urine on the wall of the toilet bowl, the flushing difficulty is greatly reduced, and the water-saving toilet bowl is also beneficial to water saving. The preparation process brief introduction: because of this location, some internal leakage between the circular cylinder and the circular piston is of little consequence. Therefore, the shape of the arc cylinder barrel and the arc piston is not a perfect circle because the arc cylinder barrel and the arc piston are bent by the pipe bender, the arc cylinder barrel and the arc piston are bent by the same process but moulds with different diameters, and the shapes of the arc cylinder barrel and the arc piston are matched, so that the requirements of form and position tolerance of the arc cylinder barrel and the arc piston can be met.
