Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1:

as shown in fig. 1-11: the embodiment discloses an improved damper for providing a damping force to a rotation of a toilet lid, comprising:

a housing 10 having an oil chamber 11;

a rotating shaft 20 which is in sealed rotating fit with the oil chamber 11 and is provided with a blade 21 extending outwards along the radial direction of the shell 10, wherein the blade 21 divides the oil chamber 11 into a first oil chamber and a second oil chamber;

the shifting piece 30 is matched with the blade 21 to form an oil passing gap 40 for communicating the first oil cavity and the second oil cavity, and the shifting piece 30 moves between positions for opening and closing the oil passing gap 40;

and an elastic member 50 provided between the vane 21 and the paddle 30, for providing an elastic force to the paddle 30 in a direction to close the oil passing gap 40.

In this embodiment, the elastic element 50 is an elastic arm disposed on the pick 30.

In this embodiment, the blade 21 is provided with a slope 22, and the elastic arm is elastically deformed along the slope 22.

In this embodiment, the blade 21 is provided with a groove 23 corresponding to the elastic arm, and the inclined surface 22 is located at one side of the groove 23.

In this embodiment, the pick 30 is provided with a protrusion 31, and the protrusion 31 provides a friction force for switching the pick 30 between the open position and the closed position.

In this embodiment, the inner wall of the housing 10 is provided with a baffle 12 extending inward along the radial direction of the housing 10, and an oil passage 60 is formed between the baffle 12 and the rotating shaft 20.

In this embodiment, the pick 30 is a concave structure inserted into the outer end of the blade 21.

The specific working process of this embodiment:

in the initial state, the elastic arm is matched with the inclined surface 22 on the blade 21 to form a supporting force, so that the shifting piece 30 is always attached to the blade 21;

when the rotating shaft 20 rotates forward (the cover plate is lifted), the elasticity of the elastic arm is overcome, and the attached poking sheet 30 moves from the position of closing the oil passing gap 40 to the position of opening the oil passing gap 40, so that the purpose of light opening is achieved;

when the rotating shaft 20 rotates reversely (the cover plate falls down), the elastic arm and the inclined plane 22 are matched and reset, the shifting sheet 30 moves from the opening position to the position for closing the oil passing gap 40 quickly and is attached to the blade 21 quickly, and therefore quick oil sealing is achieved, and the effect of slow descending and silencing is achieved; particularly, when the small angle is opened, the poking sheet 30 is affected by the elasticity of the elastic piece 50 and is quickly attached to seal oil, so that the requirement of quick response and slow descent function is met.
