Abstract

A scanning flushing toilet has a main flushing body in the shape of a semicircular hydraulic water tank. 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 flushing toilet

Technical Field

The invention belongs to a toilet bowl flushed by a scanning flushing mechanism, and particularly relates to a flushing mechanism of a toilet bowl, which is more water-saving than the existing toilet bowl when the flushing amount of the toilet bowl is required.

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 internal air pressure and the external air pressure of the airplanes when the airplanes fly in the air, and a vacuum pump does not need to be started), high-speed rails and the like, and the places with high water saving requirements are provided. 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? Therefore, the water saving of the toilet bowl is a problem which is desired to be solved for a long time but not solved ideally, and the toilet bowl has small progress in water saving, so that the overall benefit of the society is huge.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: because a plurality of places need the toilet bowl which saves more water than the existing toilet bowl, for example, in a public place of a temporary large-scale meeting, the toilet bowl arranged in the temporary toilet bowl is actually a container type toilet bowl (sometimes the toilet is built on a high platform, and the toilet bowl is put on the ground), the container capacity is necessarily limited, and the requirement can be met only by saving water; water is also saved in passenger transport vehicles; the domestic toilet bowl is mostly the same toilet bowl of stool and urine sharing, and to the man when urinating, because the width of toilet bowl is shorter a lot than length, the urine can urinate to the urinal edge sometimes, even the outside. If a urinal with a circular diameter equivalent to the length of the urinal of the existing toilet bowl is used, men rarely urinate out of the urinal, and the like. The invention aims to solve the problem of water saving of the toilet bowl, and certainly, the problem of the condition that urine flows out of the toilet bowl is better solved. The measures are as follows: the flushing mechanism of the bedpan preferably adopts a specially designed semicircular-ring-shaped hydraulic water cylinder type design, the semicircular-ring-shaped hydraulic water cylinder type design is assembled at the upper edge of a circular urinal in pairs and symmetrically in a stacking mode, under the action of water pressure during flushing, a hollow-pipe-shaped semicircular-arc-shaped piston rod with a sealing head does circular arc motion towards the outside of the semicircular-ring-shaped hydraulic water cylinder, water is sprayed outwards from a nozzle positioned at the end of the hollow-pipe semicircular-arc-shaped piston rod through a water spraying groove, and each flushing half edge of the pair of flushing mechanisms is symmetrically installed and used for carrying out 360-degree scanning flushing on the bedpan (the bedpan is required to be. 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 the toilet, the flushing mode has much larger invariable flushing pressure, has better effect than the existing toilet, can reduce flushing time, naturally reduce water consumption, and is simple in principle. Water conservation is particularly important for temporarily erected toilet bowl volumes where the toilet is limited (temporary locations, naturally limited in toilet waste volume). The toilet of the invention is not provided with a water tank, which can save some space, the shape of the toilet seat is basically the same as that of the existing toilet seat, and the middle section of the toilet seat is suspended and can not be supported on the edge of the urinal like the toilet seat of the existing toilet seat when the toilet seat is in the use position. The pedestal pan is supported on a special edge of a urinal through a toilet seat rotating shaft, a supporting hinge and a convex edge at the front end of the toilet seat to form three-point support. Unlike available toilet, the toilet seat has hinges and toilet seat ring which are firm to bear the force and moment produced by great span, and the toilet seat cover is circular and matched with the mouth of the toilet seat. When the ring and the cover are opened, the urinal opening is round, which is much larger than the urinal opening of the prior toilet, thus effectively reducing the possibility that men urinate out of the urinal, and being particularly suitable for public places. Because the water tank is not arranged, the occupation of the water tank can be accepted. The flushing is preferably realized by an electromagnetic water valve, after a person presses a button once, the electric appliance is turned off in a delayed mode, and the flushing is determined to be carried out for several times, and the flushing can be adjusted and determined on the electric appliance. The flushing action is like the action when the bicycle is locked. The flushing quantity required by the toilet bowl for achieving the flushing cleanness is much less than that of a toilet bowl. The flush procedure is described briefly as: the flushing main body is a semicircular annular tubular hydraulic water cylinder type structure, the appearance of the flushing main body is provided with a nozzle walking groove with the length of a half inner ring, the semi-ring section is also used as a hollow pipe semi-circular arc piston rod running guide pipe of the semi-circular tubular hydraulic water cylinder, when the semicircular ring tubular hydraulic water cylinder is filled with water, the pressure water overcomes the elasticity of the tension spring, pushes the hollow tube semicircular arc-shaped piston rod 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 hollow tube semicircular arc-shaped piston rod, when the water supply is stopped, the hollow pipe semi-circular arc piston rod retracts under the pulling of the tension spring inside the hollow pipe semi-circular arc piston rod, and the residual water in the hollow pipe semi-circular arc piston rod is extruded out to the wall of the toilet bowl through the nozzle at the forefront end of the hollow pipe semi-circular arc piston rod. Because of the place, some internal leakage between the circular cylinder barrel of the semicircular tubular hydraulic water cylinder and the hollow pipe semicircular arc piston rod has no influence. Therefore, the arc cylinder barrel of the semicircular ring tubular hydraulic water cylinder and the hollow pipe semicircular arc piston rod are bent by the pipe bender, the circle is not a perfect circle, the same process is used, the stress is equivalent, only the moulds with different diameters are bent, and the shapes are matched, so that the requirements of form and position tolerance of the two can be met. The manufacture is simpler. The nozzle walking groove with the length of the half inner ring is externally provided with a water-retaining side edge which is rotated by 90 degrees, so that the elbow-shaped nozzle can be eliminated, and only the water spraying hole faces the water-retaining side edge, and water is turned under the action of the water-retaining side edge to impact the toilet bowl wall during flushing. Has the advantages that: the round toilet bowl is effectively and water-saving flushed, and the flushing requirement of the toilet bowl with high water-saving requirement is met. Certainly, water saving is a constant general topic, and in order to save water in places such as airplanes and the like, huge vacuum type facilities are used, so that the effect is obtained, and meanwhile, considerable cost is brought, and inevitable noise, difficult maintenance and other adverse factors are brought. Therefore, the vacuum toilet continues to save water. If the design of using a vacuum toilet is avoided, the disadvantages of the vacuum toilet are avoided. Thereby greatly improving the flushing environment. Under the condition of a toilet bowl for both urination and defecation in a family or a public place, the scanning type flushing toilet bowl of the invention enlarges the width of the urinal, thereby greatly reducing the condition that men urinate out of the urinal, having the same comfort level as the existing toilet bowl and effectively controlling the urine pollution. And because the water tank is not arranged, the actual space is not larger than that of the existing toilet. Therefore, the advantages are very outstanding.

Detailed Description

The toilet bowl flushing mechanism preferably adopts a specially designed semicircular-ring-shaped hydraulic water cylinder 18 type design, and is symmetrically stacked at the upper edge of a circular urinal (or an annular semicircular-arc hydraulic water cylinder flushing part is installed in the upper wall of the urinal specially designed for the toilet bowl flushing mechanism to be beneficial to cleaning). in flushing, under the action of water pressure, a hollow-tube semicircular-arc-shaped piston rod 183 with a sealing head performs circular-arc motion towards the outside of the semicircular-ring-shaped hydraulic water cylinder on one side and sprays water outwards from a water spraying hole 185 of a water spraying nozzle positioned at the end of the piston through a nozzle outlet groove 187, and a pair of symmetrically installed flushing mechanisms are added at each flushing half edge to carry out 360-degree scanning type flushing on the toilet bowl. 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 the toilet, the flushing mode has much larger invariable flushing pressure and better effect compared with the existing toilet. Water conservation is particularly important for temporarily erected toilet bowl volumes where the toilet is limited (temporary locations, naturally limited in toilet waste volume). The scanning flushing toilet 32 of the present invention has no cistern and can save some space, and its ordinary shape toilet seat 35 is basically the same as that of the existing toilet seat, but its middle section is suspended and can not be supported on the edge of the urinal like the toilet seat of the existing toilet seat. The pedestal pan of the invention is erected on a special edge of a urinal through a toilet seat rotating shaft, a supporting hinge 36 and a toilet seat supporting edge 34 at the front end of the toilet seat to form three-point support. Unlike available toilet, the toilet seat has hinges and toilet seat ring which are firm to bear the force and moment produced by great span, and the toilet seat cover is circular and matched with the mouth of the toilet seat. When the ring and the cover are opened, the urinal opening is round, which is much larger than the urinal opening of the prior toilet, thus effectively reducing the possibility that men urinate out of the urinal, and being particularly suitable for public places. Because the water tank is not arranged, the occupation of the water tank can be accepted. The flushing is preferably performed by using an electromagnetic water valve (certainly, the flushing can be manually controlled by a ball valve, and the flushing can be performed by a person who presses a button once, the electric appliance is closed in a delayed mode, and the flushing is determined for several times, and the flushing can be adjusted and determined on the electric appliance. The flushing action is like the action when the bicycle is locked. The flushing quantity required by the toilet bowl for achieving the flushing cleanness is much less than that of a toilet bowl. The flush procedure is described briefly as: the flushing main body is a semicircular annular tubular hydraulic water cylinder type structure, the appearance of the flushing main body is provided with a nozzle walking groove with the length of a half inner ring, the semi-ring section is also used as a semi-circular arc hollow tube semi-circular arc piston rod operation guide tube of the semi-circular ring tubular hydraulic water cylinder, when the semicircular ring tubular hydraulic water cylinder is filled with water, the pressure water overcomes the elasticity of the tension spring, pushes the hollow tube semicircular arc-shaped piston rod 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 hollow tube semicircular arc-shaped piston rod, when the water supply is stopped, the hollow pipe semi-circular arc piston rod retracts under the pulling of the tension spring inside the hollow pipe semi-circular arc piston rod, and the residual water in the hollow piston is squeezed out to the wall of the toilet bowl through the nozzle at the forefront end of the hollow pipe semi-circular arc piston rod. Because of the place, some internal leakage between the circular arc cylinder barrel of the semicircular annular tubular hydraulic water cylinder and the circular arc hollow tube semicircular arc piston rod has no influence. Therefore, the shape of the circular arc cylinder barrel of the semicircular ring tubular hydraulic water cylinder and the shape of the circular arc hollow tube semicircular arc piston rod are not a perfect circle because the circular arc cylinder barrel and the circular arc hollow tube semicircular arc piston rod are bent by the pipe bending machine, the circular arc cylinder barrel and the circular arc hollow tube semicircular arc piston rod are subjected to the same stress by the same process, only the circular arc cylinder barrel and the circular arc hollow tube semicircular arc piston rod are bent by dies with different diameters, and the shapes of the circular arc. The manufacture is simpler. The nozzle walking groove with the length of the half inner ring is externally provided with a water-retaining side edge which is rotated by 90 degrees, so that the elbow-shaped nozzle can be eliminated, and only the water spraying hole faces the water-retaining side edge, and water is turned under the action of the water-retaining side edge to impact the toilet bowl wall during flushing.
