The specific embodiment

As shown in the figure, the cushion of toilet and the automatic closing device of lid comprise the controller of

seat cushion

1,2, two actuating units of lid, control actuating unit.

Among the embodiment 1 shown in Figure 1, the lid actuating unit comprises the gearbox 3A of micromachine 4A and this minitype motor driving, and the seat cushion actuating unit comprises the gearbox 3B of micromachine 4B and this minitype motor driving.By Fig. 3 and Fig. 4 as can be known seat cushion 1, lid 2 be separately fixed on seat pad axis 10 and the lid axle 5, seat pad axis 10 and lid axle 5 then are hinged on respectively on the base 11.Connect effect and moulding attractive in appearance for promoting, the utility model also is divided into two one-tenth two minor axises with seat pad axis 10 and lid axle 5 homogeneous; Lack

seat pad axis

10A, 10B coaxial line among Fig. 1 as can be known, and be separately fixed at two sides (becoming cantilever-shaped) of seat cushion, hinged with base 11;

Short lid axle

5A, 5B be coaxial line also, is separately fixed at two sides of seat cushion, and hinged with base 11.Also as can be known, gear 7A is equipped with in the end of the left end of seat pad axis 10 (or short seat pad axis 10A) among the figure, and this gear and gearbox 3A gears engaged realize transmission of power; Torsion spring 8B and protruding nail 12 are equipped with in the end of the right-hand member of seat pad axis 10 (or short seat pad axis 10B), and two ends of this torsion spring are separately fixed on base 11 and the protruding nail 12, to help the unlatching of seat cushion.In like manner, gear 7B is equipped with in the end of the right-hand member of lid axle 5 (or short lid axle 5B), and this gear and gearbox 3B gears engaged realize transmission of power; Torsion spring 8A and protruding nail 13 are equipped with in the end of the left end of lid axle 5 (or short lid axle 5A), and two ends of this torsion spring are separately fixed on base 11 and the protruding nail 13, to help the unlatching of lid.

For improving the engagement effect, the output of each gearbox has also adopted cog belt and seat pad axis gear and the engagement of lid shaft gear respectively.As seen, the gear 18 on the gearbox 3B output shaft 20 adopts cog belt 6B transferring power with lid shaft gear 7B among Fig. 2; In like manner, gear on the gearbox 3A output shaft and seat pad axis gear 7A also adopt cog belt 6A transferring power.

Also as can be known, gear on the output shaft 4-1 of motor 4B and gearbox gear also adopt cog belt 16 transmissions among Fig. 2, can significantly reduce running noise.

Among the embodiment 2 shown in Figure 5, only be that with the difference of aforementioned mechanism micromachine and gearbox in each actuating unit are replaced by variable speed electric motors, particularly 23A, 23B, all the other mechanisms are identical.

Also be provided with installing

hole

9A, 9B among the figure.

In addition, cushion and other components and parts that cover automatic closing device as integrated circuit controller, transformer, switch, infrared probe etc., all can be continued to use the described content of 03251196.5 patent; And the equal buyable of these components and parts obtains.

Operation principle of the present utility model is: when the toilet user walked close to toilet, infrared probe recorded signal, even the controller micromachine rotates, under the help of torsion spring, lid is opened slowly, and perhaps according to preestablishing, seat cushion is opened together; Go to toilet after the end, according to the signal command micromachine counter-rotating of infrared probe, simultaneously slowly close again by lid or lid and seat cushion for controller.
