Invention embodiment

Embodiments of the invention

The detailed description of the specific embodiments, structures, features and functions of the present invention in accordance with the present invention are set forth in the accompanying drawings and claims.

Fig. 1 is a structural view showing a toilet lid according to a first embodiment of the present invention. Referring to FIG. 1, the toilet cover includes a toilet cover main body 10 and a base 20. The toilet lid main body 10 includes an upper cover 11 and a seat 13 .

Fig. 2 is a partial enlarged view of a portion A of Fig. 1. Referring to FIG. 2, the upper cover 11 is fixedly coupled with the upper cover shaft 110. The upper cover shaft 110 is partially received in the upper cover shaft base 110a, and the upper cover shaft base 110a is fixedly connected to the toilet. As in the prior art, the upper cover 11 and the seat 13 can be rotated between the uncovered state and the covered state, that is, the upper cover 11 and the seat 13 can be uncovered for the user to use and cover the toilet. The covering direction is a direction in which the uncovering state is rotated toward the covering state, and the uncovering direction is a direction in which the covering state is rotated toward the uncovering state.

The seat ring 13 is connected and fixed with a seat shaft 130. The toilet cover further includes a torsion mechanism for twisting the seat shaft or the seat ring. The torsion mechanism includes a torsion spring sleeved outside the seat shaft, and a seat fixed to the toilet seat. The ring shaft base is partially accommodated in the seat shaft base 20, the seat shaft base 20 is used for supporting the rotation of the seat shaft 130, the seat shaft base 20 is fixedly connected with the toilet, and the seat shaft 130 is jacketed. There is a torsion spring 1301, one end of the torsion spring 1301 is fixedly connected with the seat ring 13, and the other end of the torsion spring 1301 is fixedly connected with the seat shaft base 20; during the rotation of the seat ring 13 from the uncovered state to the covering state, the torsion spring 1301 The deformation produces torque. The deformation of the torsion spring 1301 to generate torque can cause the race 13 to rotate from the covered state to the uncovered state, that is, the race 13 can be automatically raised. Avoid touching the gap between the seat and the toilet by hand. In other embodiments, one end of the torsion spring 1301 is fixedly coupled to the race shaft 130, and the other end of the torsion spring 1301 is fixedly coupled to the race shaft base 20.

The torque generated by the deformation of the torsion spring 1301 can be set or selected according to requirements, and is preferred in the present invention. The torque generated by the deformation of the torsion spring 1301 is greater than the lifting torque of the seat ring 13 and is smaller than the sum of the lifting torques of the upper cover 11 and the seat ring 13. Thus, when the upper cover 11 and the seat 13 are in the covering state, the upper cover 11 and the seat 13 cannot be lifted, and when only the seat 13 is covered, the seat 13 can be automatically raised.

3 is a structural view of a seat shaft base of the toilet lid of FIG. 1. Referring to FIG. 3, the lifting speed of the seat 13 is too fast, which may cause the seat 13 to collide with the upper cover 11 to generate noise and affect the user's use. In order to prevent the lifting speed of the seat 13 from rising too fast, the applicant performs the seat shaft base 20 on the seat shaft base 20 Improvements.

The seat shaft base 20 has a hollow structure, and the seat shaft base 20 has a casing 21 in which a sealed damping oil receiving chamber is formed, and the damping oil receiving chamber is filled with damping oil. A portion of the race shaft 130 is received within the damping oil receiving chamber, and the race shaft 130 extends out of the partition plate 1303 within the damping oil receiving chamber. The partition plate 1303 is in close contact with the race shaft 130 and the inner surface of the outer casing 21, that is, the partition plate 1303 and the race shaft 130 divide the damping oil receiving chamber into two chambers. The partition plate 1303 is provided with a through hole through which the valve 23 is accommodated.

Fig. 4 is a partial enlarged view of the portion B of Fig. 3. Fig. 4 is a partial enlarged view of the portion B of Fig. 3. Figure 5 is a perspective view of the valve of Figure 4. Fig. 6 is a cross-sectional structural view showing the valve of Fig. 5. Referring to FIGS. 4, 5, and 6, the damping oil between the two chambers can only pass through the valve 23, and the valve 23 includes a first enlarged end portion 231, a second enlarged end portion 232, and a hollow connecting tube 230.

The first enlarged end portion 231 is fixed to the one side of the hollow connecting pipe 230 to fix the limit projection 233b, and the second enlarged end portion 232 is provided with a small hole 232a communicating with the inside of the hollow connecting pipe 230 as a uncovering direction communicating portion.

The hollow connecting pipe 230 is located between the first enlarged end portion 231 and the second enlarged end portion 232 and is fixedly connected to the first enlarged end portion 231 and the second enlarged end portion 232. The hollow connecting pipe 230 has a passage 230a inside, and the side wall of the both ends of the hollow connecting pipe 230 is provided with a large hole 230b covering the directional communicating portion.

The working principle of the valve 23 is:

When the race 13 rotates from the uncovering state toward the covering state, the limiting protrusion 233b abuts against the partitioning plate 1303, and the two chambers communicate with each other through the large hole 230b, and the damping oil flows at a high speed, that is, the rotating speed of the seat shaft 130 is affected. Small buffer.

When the seat 13 rotates from the covering state to the uncovering state, the second enlarged end portion 232 is in contact with the partitioning plate 1303, and the two chambers communicate with each other through the small hole 232a, and the damping oil flow speed is limited by the size of the small hole 232a, that is, the seat ring The rotational speed of the shaft 130 is greatly affected by the cushioning.

In other embodiments of the invention, when the partitioning plate 1303 has a suitable space with the race shaft 130 and the outer casing 21 The damping oil between the two chambers through the gap can flow through the gap and the gap can serve as the uncovering direction communication portion. This eliminates the need to open the aperture 232a.

In other embodiments of the invention, the aperture 232a is defined in the divider 1303.

In other embodiments of the present invention, the first enlarged end portion 231 may not be provided, and the limiting protrusion 233b is fixed to the outer wall of the hollow connecting tube 230, and the hollow connecting tube 230 is opened only at the end near the second enlarged end portion 232. There are large holes 230b.
