Description of the embodiments
The invention is further described below in connection with specific embodiments,
The lifting closestool comprises a closestool main body 2, wherein an upper column sleeve 11 is arranged at the rear part of the closestool main body, a lower column sleeve 5 is arranged at the lower part of the upper column sleeve 11, the lower column sleeve 5 is fixed on a base, and the upper column sleeve 11 and the lower column sleeve 5 are sleeved into a whole and can be relatively telescopic; the inner wall of the lower column sleeve 11 is provided with an internal thread part 21, and the internal thread part is screwed with a screw rod seat 9; the inner side of the upper column sleeve 11 is provided with a supporting part which is propped against the upper side of the screw seat 9; a driving motor is fixedly arranged in one of the upper column sleeve 11 and the lower column sleeve 5; the motor shaft of the driving motor is inserted into the center of the screw seat 9 and linked. The upper column sleeve 11 is adjusted to extend or retract into the lower column sleeve 5 through the up-and-down movement of the screw seat 9, so that the lifting of the toilet main body is controlled, and the structure is simple and stable.
The supporting part is a baffle ring 17 formed on the inner wall of the upper column sleeve; the driving motor is a stepping motor; the lower column sleeve 5 is arranged outside the upper column sleeve 11, and a motor shaft 16 of the stepping motor extends downwards and drives the screw rod seat 9.
A spring 10 is arranged in the lower column sleeve at the lower part of the screw seat, and the upper end of the spring is propped against the screw seat 9. The design of the spring can offset the downward pressure indirectly given to the screw seat 9 by the closestool body, so that the rotating effect of the screw seat is improved, and the noise is reduced.
The lower side of the screw seat 9 is provided with a second plane bearing 13, and the upper end of the spring is propped against the second plane bearing 13. The second plane bearing 13 can greatly reduce noise and prolong service life.
An inner hole 20 is formed in the middle of the lower side of the screw seat, and a second plane bearing 13 is arranged at the bottom of the inner hole; the upper end of the spring extends into the inner hole and abuts against the lower side of the plane bearing II 13.
The upper side of the screw rod seat is provided with a step part, the step part is provided with a first plane bearing 12, and the lower side of the supporting part is propped against the upper part of the first plane bearing 12. The planar bearing 12 can reduce noise.
The middle part of the screw rod seat is provided with a connecting hole 19, and the connecting hole 19 is a straight hole, a cross hole or a spline hole; the lower end of the motor shaft is matched with the connecting hole.
The connecting hole is a through hole. When the screw rod seat moves to one side where the motor is located, the motor shaft can conveniently extend out of the connecting hole, and the travel limit of the motor shaft given by the screw rod seat is relieved.
The screw seat on one side of the connecting hole is vertically provided with an air pressure balance hole 18 which communicates with the upper side and the lower side of the screw seat. The pressure of the inner cavities of the upper column sleeve and the lower column sleeve is balanced, so that the lifting resistance of the resistance screw seat is reduced, and the noise is reduced.
The outer side of the upper column sleeve 11 is provided with a dustproof and dampproof decorative tube 4. The inner diameter of the dustproof and dampproof decorative pipe is slightly larger than the outer diameter of the lower column sleeve, so that dust and liquid are not easy to enter the inner cavity of the lower column sleeve.
The toilet body 2 is a metal piece, so that the strength of the toilet body is improved.
The inside of the closestool body downwards extends out of a water draining hose 7, and the outer side of the water draining hose is sleeved with a corrugated pipe 3.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
