Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0021] like figure 1 , 2 As shown, the present invention includes a pillow core frame 1 and a bottom plate 4 , the rear ends of the pillow core frame 1 and the bottom plate 4 are hinged to each other through a connecting shaft 5 , and the pillow core frame 1 can rotate around the connecting shaft 5 . Wherein, the back side of the pillow core frame 1 is provided with a tailgate 2, and the pillow core frame 1 is also provided with at least two side stop mechanisms 3 perpendicular to the direction of the tailgate 2. The concave portion surrounded by the side block mechanism 3 and the tailgate 2 is used for placing pillow cores. For a single pillow, there are two side block mechanisms 3, such as figure 1 shown. For the pillow for two persons, there are three side blocking mechanisms 3, which form two recessed parts for separately placing pillow cores respe...

Abstract

The invention discloses an automatic damped height regulating pillow. A spring is arranged between a spring support of a pillow lifting damping mechanism and a pillow bottom plate; a hydraulic cylinder sleeve is arranged in the spring, the upper end of a piston rod of a piston in the hydraulic cylinder sleeve is connected with the spring support; the upper end of the hydraulic cylinder sleeve is provided with an oil storing cylinder sleeve with internal diameter more than that of the hydraulic cylinder sleeve, an upper port of the oil storing cylinder sleeve is provided with an oil seal seat body and an oil seal; and the vertical distance from the lower end face of an oil seal assembly to the upper end face of the hydraulic cylinder sleeve is less than the thickness of the piston. The invention has the advantages of ensuring that the whole damped mechanism has a small structure and is convenient for assembly, eliminating the idle stroke of the operation of the piston, realizing the complete damping of the operation process of the piston, and ensuring that the pillow cannot have failed damping in the beginning of the dropping during the lifting.

Description

technical field [0001] The invention relates to a pillow, in particular to a pillow whose height is automatically adjusted according to the pressure change. Background technique [0002] When a person is lying on his side, due to the supporting effect of the shoulders, the requirement for the height of the pillow is higher than that when lying on his back. That is, under normal circumstances, people need pillows of two heights due to the change of prone position when sleeping, but the heights of most existing pillows cannot be automatically adjusted. [0003] The Chinese invention patent whose publication number is CN101773350A discloses a "damping type height-adjusting pillow automatically". By adopting a damping mechanism, the height of the pillow can be automatically adjusted as the pressure changes. The spiral damping mechanism in it ensures that the lifting movement is slow and soft when the height of the pillow changes. [0004] In practice, it has been found that th...
