Detailed Description
The embodiment of the invention provides an auxiliary pulling device for a power plug of a kettle, which comprises a plug 10 connected with the kettle, a sleeve 1, a pneumatic cavity 2, a wind wheel 4, a wire coil 6, a supporting plate 7, a sleeve die 9 and a pull rope 14, and is shown in figures 1-5. The sleeve 1 is used for being sleeved on the kettle cover, the air pressure cavity 2 is arranged on the sleeve 1, the wind wheel 4 is pivoted in the air pressure cavity 2, the sleeve 1 is communicated with the air pressure cavity 2 through the communicating pipe 3, and the top of the air pressure cavity 2 is provided with the exhaust pipe 5. The sleeve 1 is used for receiving steam emitted by the kettle cover, the steam enters the air pressure cavity 2 through the communicating pipe 3 and drives the wind wheel 4 to rotate, and finally the steam is discharged from the exhaust pipe 5.
The wire coil 6 is pivoted outside the air pressure cavity 2 and is coaxially connected with the wind wheel 4, and the wind wheel 4 rotates to drive the wire coil 6 to rotate synchronously. The front end of the supporting plate 7 is provided with a patch board 8 which can be inserted into a socket, and the structure of the patch board 8 is conventional for electrically conducting the socket and the plug 10. When in use, the patch board 8 on the supporting plate 7 is inserted into the socket to relatively fix the supporting plate 7. The cover die 9 is sleeved outside the plug 10, the plug 10 can be inserted into the patch board 8, and the cover die 9 is used for moving the linkage plug 10. The cover die 9 is concave, the two ends of the cover die 9 are pivoted with the baffle plates 20, and the baffle plates 20 can block the plug 10 after rotating. After the cover die 9 is sleeved on the plug 10, the baffle 20 is rotated to block the plug 10 to prevent the plug from falling off from the cover die 9.
Be provided with guide bar 11 along its length direction on the backup pad 7, sliding sleeve is equipped with guide block 12 and balancing weight 13 on guide bar 11, and guide block 12 links to each other with cover die 9, and guide block 12 drives cover die 9 synchronous motion. The guide block 12 is connected with a balancing weight 13 through a plurality of tension belts 15, and the balancing weight 13 can be made of metal. A plurality of tension bands 15 are equiangularly distributed around the center of the counterweight 13. The counterweight block 13 slides on the guide rod 11 to firstly stretch the tension belt 15, and when the tension belt 15 is stretched to the limit, the sleeve die 9 can be instantly pulled out of the patch board 8 under the action of potential energy of the counterweight block 13.
One end of the pull rope 14 is fixedly wound on the wire coil 6, and the other end of the pull rope is connected with the balancing weight 13. The pulling rope 14 is used for pulling the counterweight block 13 to slide on the guide rod 11.
As shown in fig. 4, when using, cover sleeve 1 on the top cover of kettle, wiring board 8 inserts on the socket, cover mould 9 covers on plug 10 simultaneously, insert plug 10 on wiring board 8, when water is boiled, the venthole of kettle top cover can spout a large amount of high atmospheric pressure gas and drive wind wheel 4 and rotate, wind wheel 4 drives drum 6 and rotates stay cord 14 winding above that, 14 pulling balancing weights 13 of stay cord, utilize the potential energy of balancing weights 13 and the tension of tension band 15 to pull cover mould 9 from wiring board 8 down, thereby plug 10 cuts off the power supply with the socket during, avoided owing to forget to pull out the produced potential safety hazard of plug 10.
In order to avoid that when water is not boiled, the pull rope 14 drives the balancing weight 13 to move, one end of the pull rope 14, which is far away from the wire coil 6, is connected with the balancing weight 13 through the non-Newtonian buffer mechanism 16, the non-Newtonian buffer mechanism 16 comprises a cylinder body 161 and a piston rod 162, the piston type sliding fit of the piston rod 162 is arranged in the cylinder body 161, the cylinder body 161 is filled with non-Newtonian fluid 163, the bottom of the cylinder body 161 is connected with the balancing weight 13, and the pull rope 14 is connected with the piston rod 162. When the pulling rope 14 slightly pulls the piston rod 162, the piston rod 162 can slide in the non-newtonian fluid 163 in the cylinder 161, and when the pulling force of the pulling rope 14 is large, the piston rod 162 is instantaneously squeezed to harden the non-newtonian fluid 163, so that the cylinder 161 moves synchronously with the piston rod 162.
As shown in fig. 5, when water is not yet boiled but gas slowly comes out from the kettle cover, the wind wheel 4 is only slowly driven to rotate due to low air pressure, at this time, the pull rope 14 drives the piston rod 162 to slowly slide in the non-newtonian fluid 163 in the cylinder body 161, and the cylinder body 161 does not displace, so that the plug 10 is firmly inserted into the socket; when the air pressure which is emitted from the kettle cover after the water is boiled is increased, the pull rope 14 can quickly pull the piston rod 162, and the non-Newtonian fluid 163 becomes hard after the displacement of the piston rod 162 is quickened, so that the cylinder body 161, the balancing weight 13 and the like are synchronously driven to synchronously move, and the plug 10 is triggered to be pulled out from the patch board 8; the plug 10 is prevented from falling off the patch board 8 when water is not boiled.
The counterweight block 13 is provided with a first magnetic sheet 18, the supporting plate 17 is provided with a second magnetic sheet 19 matched with the first magnetic sheet 18, and when the first magnetic sheet 18 and the second magnetic sheet 19 are attracted, the guide block 12 and the counterweight block 13 are in an unstrained state. The magnetic force between the first magnetic sheet 18 and the second magnetic sheet 19 is weak. When the water is not boiled, the counterweight block 13 can be fixed in place, and when the pulling force of the pulling rope 14 is large, the counterweight block 13 moves to enable the magnetic sheet I18 and the magnetic sheet II 19 to rub and displace with each other and finally separate from each other.
The support plate 7 is provided with at least one guide ring 17 along its length, the pull cord 14 passing through the guide ring 17. The guide ring 17 is used to move the pull cord 14 along the longitudinal direction of the guide bar 11.
The bottom of the sleeve 1 is provided with a cylindrical elastic cloth bag 21, and the bottom of the elastic cloth bag 21 is provided with a tightening belt 22 in the circumferential direction. Can remove to match according to the kettle lid that does not use the size of a dimension, no matter how the size of a dimension of kettle lid is, elasticity sack 21 can both overlap on it to through tightening belt 22 firmly locking, make sleeve 1 and kettle lid cooperation, the commonality is stronger.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
