Description
Technical Field
The invention relates to the technical field of kitchen appliances and parts thereof, in particular to a damping device and a device comprising the damping device.
Background
Containers such as electric cookers, which require frequent opening of the upper lid, often use structures such as torsion springs to drive the upper lid to open. In view of the fact that the driving structure still applies a relatively large pushing force when the upper cover is opened and is about to be in place, which causes the connection part of the upper cover and the pot body to be violently impacted, a damping device is usually needed. When the upper cover is opened to be in place, the damping device provides greater resistance, and the movement speed of the upper cover is slowed down until the upper cover stops.
The structure and installation position of the existing damping device are shown in fig. 1 and fig. 2, a first rotating shaft 140 is arranged between the upper cover 100 and the pan body 120, two torsion springs 180 and a driving structure 160 located between the two torsion springs 180 are sleeved on the first rotating shaft 140, and the damping device 200 is arranged on the pan body 120 and is independent with respect to the first rotating shaft 140. The damper device 200 includes an operating member 201, a stationary member 202, a second rotating shaft 203, and an annular cover 204. The static part 202 is arranged in the action part 201, the static part 202 and the annular cover 204 are all sleeved on the second rotating shaft 203, and the second rotating shaft 203 is arranged on the pot body 120. Two ends 181 of the torsion spring 180 are respectively installed on the upper cover 100 and the pot body 120, and the first rotating shaft 140 drives the driving structure 160 to rotate when the upper cover 100 is opened. The driving structure 160 is a gear engaged with the convex teeth 201a on the outer side of the operating member 201. When the driving structure 160 rotates, the driving structure 160 drives the actuating member 201 to move together, when the actuating member 201 rotates until the inner rib of the actuating member 201 abuts against the rib on the outer wall of the stationary member 202, the stationary member 202 starts to prevent the actuating member 201 from rotating, and then the actuating member 201 also starts to prevent the driving structure 160 from rotating, and the driving structure 160 transmits the blocking force to the torsion spring 180 through the first rotating shaft 140, so as to slow down the moving speed of the upper cover 100 until the movement is stopped.
The drawbacks of this structure include: 1. the driving structure 160 is required to transmit the thrust of the torsion spring 180 to the damping device 200, the driving structure 160 and the action member 201 are required to be processed into meshed gear structures, an independent second rotating shaft 203 is required to be added, the number of required parts is large, and the processing cost is high, the assembly workload is large and the occupied space is large; 2. the reaction force of the damping device 200 cannot directly act on the first rotating shaft 140, so that the damping device 200 cannot rapidly damp the first rotating shaft 140; moreover, the reaction force of the damping device 200 is lost in the intermediate transmission link, which affects the damping effect.

Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The invention provides a damping device and a device comprising the same, such as an electric cooker. The electric cooker comprises an upper cover and a cooker body, wherein a non-circular articulated shaft is arranged between the upper cover and the cooker body, and the upper cover rotates around the articulated shaft when opened. As shown in fig. 3 and 4, the damping device includes an outer shell cover 1, a cover 2, a damping ring 3, and an inner core 4. The outer shell cover 1 is used for installing the damping ring 3 and the inner core 4 and installing and fixing the integral device on the pot body; the sealing cover 2 is used for enclosing with the outer shell cover 1 to form a closed space, the damping ring 3 and the inner core 4 are positioned in the closed space, and substances such as viscous liquid and the like can be added into the closed space; the damping ring 3 is arranged in the shell cover 1, and the inner core 4 is arranged in the damping ring 3; inner core 4 is connected with the articulated shaft, and the articulated shaft rotates around the axis direction when the upper cover is opened, drives inner core 4 and rotates when the articulated shaft rotates, and inner core 4 can transmit the resistance for the articulated shaft when inner core 4 receives the resistance and can't continue former fast rotation, and the articulated shaft and then slows down the opening speed of upper cover. The dotted lines in fig. 4 show the orientation of the housing cover 1, the closure 2, the damping band 3 and the core 4 when installed.
The specific way of the inner core 4 receiving resistance when rotating is as follows: as shown in fig. 4, the damping ring 3 is provided with an outer ring protrusion 31 inside, the inner core 4 is provided with an inner core protrusion 41 on an outer wall thereof, and the outer ring protrusion 31 abuts against the inner core protrusion 41 when the inner core 4 rotates to a set position, so as to reduce the rotation speed of the inner core 4.
The hinge shaft and the damping device are directly installed together, so that the whole structure is simplified, the required parts are few, the cost is reduced, and the volume of the electric cooker is reduced; the inner core 4 is directly sleeved on the hinge shaft, so that the force is transmitted more directly, timely and efficiently, and the loss of force in the transmission process is avoided.
As shown in fig. 5, the main body of the inner core 4 is a hollow tubular structure, a plate-shaped structure is disposed at a position close to the middle part in the tube, a semicircular or polygonal inner core shaft hole 42 is formed in the plate-shaped structure, and a hinge shaft having a semicircular or polygonal cross section passes through the inner core shaft hole 42, and when the hinge shaft rotates around the axis, the inner core 4 is driven to rotate in the same direction.
As shown in fig. 5 and 6, two inner core protrusions 41 made of rubber or silicon rubber are symmetrically disposed on the outer wall of the inner core 4, and two or more outer ring protrusions 31 made of rubber or silicon rubber are equally spaced inside the damping ring 3. The inner core convex blocks 41 and the outer ring convex blocks 31 both have certain strength and certain deformation, when the hinge shaft drives the inner core 4 to rotate to a set position, the outer edges of the inner core convex blocks 41 contact the outer edges of the outer ring convex blocks 31, and then the outer edges of the inner core convex blocks 41 extrude the outer edges of the outer ring convex blocks 31, so that the inner core 4 is prevented from continuously rotating, and damping force is provided for the hinge shaft.
The number of the outer ring projections 31 is greater than the number of the inner core projections 41, and during the rotation of the hinge shaft, the rotation speed of the hinge shaft becomes slow (accordingly, the opening speed of the upper cover becomes slow) when the inner core projections 41 contact and press one outer ring projection 31, and the rotation speed of the hinge shaft becomes fast (accordingly, the opening speed of the upper cover becomes fast) after the inner core projections 41 pass over the outer ring projections 31; when the inner core projection 41 contacts and presses the next outer ring projection 31, the rotation speed of the hinge shaft is slowed again (correspondingly, the opening speed of the upper cover is slowed again), and the problems of humpback and take-off of the upper cover can be effectively solved.
In order to reduce the processing difficulty, reduce the weight and facilitate the installation, the length of the outer ring bump 31 is smaller than that of the damping ring 3 along the axial direction of the damping ring 3; the length of the core projection 41 is smaller than the length of the core 4 in the axial direction of the core 4. After installation, the outer ring projections 31 are aligned with the inner core projections 41, and it is ensured that the outer ring projections 31 can apply resistance after the inner core projections 41 rotate in place.
