Description

Lifting toilet

Technical Field

The invention relates to a closestool, in particular to a lifting closestool.

Background

The height of the toilet with the lifting function can be adjusted by a user according to the actual height of the user, and the toilet is particularly convenient for children to use.

The lifting mode of the existing lifting closestool mainly has two types: the first type is that a cylinder or a jack is arranged at the bottom of the closestool, the bedpan is driven to lift through the cylinder or the jack, and the cylinder, the jack and the bedpan are in transmission connection through a scissor type lifting frame. The scissor type lifting frame has a complex structure, a large size and a low lifting speed, and is used less and less; the other type is that a motor drives a screw rod to drive, and the screw rod drives the bedpan to lift together. Compared with the first type of products, the screw rod transmission structure is simple and compact, the lifting efficiency is good, and the first type of products are gradually replaced.

At present, the transmission structure of the screw rod is that a plurality of belts are transmitted in grades, a motor drives a first-stage belt to convey, the first-stage belt drives a plurality of second-stage belts to convey, and the second-stage belts drive the corresponding screw rods to rotate. However, the multi-stage belts are arranged in a layered manner, so that more installation space is occupied in the vertical direction, and corresponding transmission gears are required to be arranged at different heights, so that the height of the toilet bowl is large, and the toilet bowl still has a large sitting height even when the toilet bowl is lowered to the lowest position.

Disclosure of Invention

The invention provides a lifting closestool, which reduces the height of the closestool and overcomes the defects of the background technology. The technical scheme adopted by the invention for solving the technical problems is as follows:

a lifting closestool comprises a bedpan, a movable frame for supporting the bedpan, a base and a motor, wherein the base is of a shell-shaped structure with an open top surface, the bottom of the bedpan passes through the abdicating hole of the movable frame and extends into the base, the front part and the rear part of the left side and the right side inside the base are both provided with screw holes, the front part and the rear part of the left side and the right side below the movable frame are respectively provided with a screw rod, the screw rods are in one-to-one corresponding screw connection with the screw holes, the upper end of the screw rod extends out of the upper surface of the movable frame and is sleeved with a driven gear, the motor is arranged below the movable frame, the output shaft of the motor extends out of the upper surface of the movable frame and is sleeved with a driving gear, the driving gear and the driven gear are arranged on a plane with the same height, the motor also comprises a conveyor belt, the belt passes around the drive gear and all driven gears, which are driven by the belt to rotate synchronously.

Compared with the background technology, the technical scheme has the following advantages:

the motor is used for driving the screw rod to rotate to lift, and the screw rod is pivoted on the movable frame, so that the screw rod drives the movable frame to lift while lifting, and finally the bedpan is lifted. Because the driving gear connected above the motor is the same as the driven gear connected above the screw rod in height, and the driving gear and the driven gear are linked through the conveying belt, the occupied space height can be effectively reduced, the height of the closestool is reduced, and the lower sitting height can be obtained when the closestool descends to the lowest position.

The upper and lower portions of the outer surface of the control box 90 are respectively provided with a photoelectric switch 92, and the photoelectric switch 92 is connected to the circuit board. The base 30 is provided with a blocking sheet 39 for cutting off the signal of the photoelectric switch 92. When the control box 90 ascends, the movable frame 20 drives the control box 90 to ascend synchronously, when the photoelectric switch 92 below the control box 90 is aligned with the blocking piece 39, the blocking piece 39 cuts off a signal of the photoelectric switch 92, and the circuit board controls the motor 40 to stop working; when the control box 90 descends synchronously, the movable frame 20 drives the control box 90 to descend, and when the photoelectric switch 92 above the control box 90 is aligned with the blocking piece 39, the blocking piece 39 cuts off a signal of the photoelectric switch 92, and the circuit board controls the motor 40 to stop working. Therefore, the toilet bowl has a limiting function when ascending to the highest point and descending to the lowest point. In this embodiment, the stop 39 is attached to a nut 36 and the opto-electronic switch 92 is U-shaped.

Preferably, the opening direction of the sewage draining outlet 11 at the bottom of the bedpan 10 is deviated towards one side of the centerline of the bedpan in the front-back direction, the sewage draining pipeline 12 connected below the bedpan 10 extends along the direction of the sewage draining outlet 11 in a backward and oblique upward direction, passes through the vertex and then extends in a direction approaching the centerline in an oblique downward direction, and the pan is returned to the vicinity of the centerline. Because this sewage pipes 12 deviates from the central line of the bedpan 10 and extends backward first, and then the central line is coiled after passing through its vertex, compare with the existing straight line and extend backward and set up the C sewage pipes, this sewage pipes 12 is set up in a horizontal staggered manner in space, make full use of the horizontal space of this bedpan 10 rear side, can reduce the whole height of this sewage pipes 12 effectively, thus reduce the height of this bedpan 10 greatly, make the height of the closestool do littleer. In particular, the waste pipe 12 is divided into a front section, a middle section and a rear section, wherein the front section is obviously arranged at one side of the central line, and the rear section is detoured to the periphery of the central line and close to the side edge of the front section towards the central line, so that the outlet of the waste pipe 12 is still close to the central line, and the waste pipe can be better adapted to the existing installation requirements.

More preferably, the sewage pipe 12 comprises a trap 121, an ascending section 122, a siphon 123 and a descending section 124 which are connected in sequence, of course, the trap 121 is communicated with the sewage outlet 11, the descending section 124 and the ascending section 122 are arranged at left and right sides when viewed from the top, and the middle is connected through the siphon 123, so that the height of the sewage pipe 12 is basically determined by the heights of the ascending section 122 and the siphon 123, and the descending section 124 is arranged at the side of the ascending section 122, does not occupy the space in the height direction, and the height of the bedpan 10 is reduced to the maximum extent. To facilitate manufacturing, the drop leg 124 is separated from the bowl 10, i.e., the drop leg 124 is manufactured separately and the remainder of the waste pipe 12 is integrally sintered to the bowl 10. the drop leg 124 interfaces with the opening at the lower end of the siphon bend 123 via a fitting. In addition, the support 26 is connected between the descending section 124 and the movable frame 20, so that the descending section 124 can be prevented from loosening during the process of lifting the bedpan 10.

In this embodiment, the opening direction of the sewage draining exit 11 forms an angle of 18 degrees with the center line, preferably 10-30 degrees. The corrugated pipe 80 is connected to the end of the sewage pipeline 12, so that the installation is convenient, and particularly, the opening at the bottom of the corrugated pipe 80 is designed eccentrically, so that the sewage pipeline can meet more installation requirements.
