Drop resistance type thermos bottle

Abstract

The invention discloses a drop resistance type thermos bottle which comprises a bottle shell and a liner in the bottle shell. A vibrating gap allowing the liner to vibrate up and down is formed between the bottom of the liner and the bottom of the bottle shell; a buffer component used for supporting the liner and buffering vibration of the liner is arranged on the inner circle of the bottle shell; the buffer component comprises a sliding sleeve fixed to the inner wall of the bottle shell along the radial direction, a sliding rod matched with the sliding sleeve, a connecting rod fixed at the outer end of the sliding rod and a damper pulley rotatably connected to the connecting rod and in rolling fitness with the outer wall of the liner; a torsional spring used for producing damping force to rotation of the damper pulley is arranged between the damper pulley and the connecting rod; a spring used for pressing the damper pulley on the outer wall of the liner is elastically abutted between the connecting rod and the sliding sleeve. By the arrangement, vibration on both the horizontal direction and the vertical direction can be buffered, and the liner is prevented from being broken when vibrated.

Description

technical field [0001] The invention relates to the field of thermos bottles, in particular to a drop-proof thermos bottle. Background technique [0002] The existing thermos bottle is made of a thermos shell and a thermos liner placed in the thermos shell. The thermos shell can be made of materials such as stainless steel, enamel, plastics, and bamboo chips. Its profile is generally cylindrical, and the profile of the thermos liner is also roughly Cylindrical, this thermos bottle is widely used in families and departments, but the existing thermos bottle has a drawback, when the thermos bottle is accidentally dropped when in use, the thermos bottle is easily broken. [0003] Therefore, need a kind of fall-proof type thermos bottle, this thermos bottle can buffer the vibration of horizontal and vertical direction, avoids bottle liner to break when being vibrated. Contents of the invention [0004] In view of this, the object of the present invention is to overcome the def...
