Abstract
The utility model discloses an electric cooker, comprising a cooker body, a cooker cover, a rotating shaft, a torsion spring and a damping device. The cooker body is hinged to the cooker cover via the rotating shaft. Both the torsion spring and the damping device are sleeved onto the rotating shaft, wherein legs at two ends of the torsion spring are connected respectively with the cooker body and the cooker cover. The damping device comprises an action component and a static component which are sleeved onto the rotating shaft, wherein the action component is sleeved into the static component to form a closed space filled with fillings. The external surface of the action component is provided with a screwed flange extending along the axial direction of the action component. When the action component rotates with respect to the static component, the screwed flange grinds and extrudes the fillings in the closed space formed by the action component and the static component to generate resistance. The resistance changes in a uniform manner and enables to realize the stable cover opening. Additionally, the damping device is simple in structure and low in cost.
Description
Technical field
The utility model relates to the cooking apparatus field, relates more specifically to a kind of electric cooker.
Background technology
Existing electric cooker generally comprises pot body and pot lid, and described pot lid is hinged by rotating shaft and described pot body, and the two ends of described rotating shaft are stuck in described pot body and pot covers in the set draw-in groove.Be arranged with some torsion springs in the described rotating shaft, the two ends leg of described torsion spring covers engagement connection with described pot body and pot respectively.When opening described pot lid, described pot covers under the effect of torsion spring and flicks.But because the problem of manufacturing process, therefore the torsion spring performance unanimity that each batch produced can exist difference between the torsion spring that batch process is come out.Such as, the torsion of some torsion spring is bigger, and the whole electric cooker of the stressed ambassador of mistake bounces when causing pot lid to be opened, thereby causes uncapping of electric cooker not steady; Otherwise the torsion of some torsion spring is less, thereby causes pot to cover stressed too small can not opening fully when opening.And in assembling process, correct above-mentioned bad phenomenon and need replace new suitable torsion spring, will cause the waste of resource and manpower like this.
In order to address the above problem, Granted publication number is " CN 201332940Y ", the Chinese patent that the utility model name is called " a kind of electric cooker " discloses following technical scheme: be arranged with damper in the rotating shaft, described damper comprises action piece and the static element that is placed on described rotating shaft.Radially be provided with a circle flange on the lateral surface of described action piece one end, when described action piece is inserted in described static element since described flange be arranged so that described action piece and and static element between constitute the confined space of obturator.In addition, be equipped with axial convex tendon on described action piece and the static element.When opening described pot lid, thereby described rotating shaft rotation drives described action piece and rotates relative to described static element, when relatively rotating between described action piece and the static element, described convex tendon friction and extruding are positioned at the described obturator of described confined space, thereby produce the resistance of uncapping, and overcoming the torsion deviation of torsion spring with this resistance, the speed that flicks that finally delays described pot lid is steadily uncapped realizing.But because described damper is provided with flange and convex tendon, make described damper structure complexity, cost is higher.In addition, because described convex tendon is along the axial setting of described action piece and static element, the change in resistance that is produced during the described obturator of friction extruding is inhomogeneous, can not well realize steadily uncapping.
Therefore, be necessary to provide a kind of improved electric cooker to overcome above-mentioned defective.
