Detailed Description

As shown in fig. 1, the cooker comprises a base 11 with a heating device, a cooker body 12 arranged on the base 11, a cooker liner arranged in the cooker body 12 and a cooker cover 13 covered on the upper end surface of the cooker body 12, wherein the cooker cover 13 is provided with a handle 14. And, be equipped with the joint switch that is used for realizing in the pot cover 13 electronic component and the control circuit board electrical connection in the pot shell 12 between pot cover 13 and the pot shell 12, this joint switch includes the plug that sets up on pot cover 13 and sets up the socket on pot body 12, thereby this joint switch connects reliably and can increase the reliability and the life of pan.

As shown in fig. 2, 3 and 4, the lid 13 is provided with a handle 14 having a handle connecting portion 15, and the plug 2 is provided on the lower end surface of the handle connecting portion 15. The plug 2 comprises a plug holder 21 having a receiving chamber 22, wherein at least one upper connecting rod 23 fixed on the plug holder 21 is arranged in the receiving chamber 22, and the upper end of the upper connecting rod 23 is electrically connected with an electronic component arranged in the pot cover 13 through a first wire 4.

As shown in fig. 5, 6 and 7, the upper end surface of the pan body 12 is annular, a boss 121 with inclination and protruding upward is provided on the upper end surface of the pan body 12, and the socket 3 is provided on the boss 121. Specifically, the receptacle 3 includes: a socket panel 30 protruding on the boss 121, the socket panel 30 having a socket 300 corresponding to the lower end of the upper link 23, the socket 300 having a chamfer structure to facilitate insertion of the upper link 23; a gasket 31 attached to the lower side of the socket panel 30, the gasket 31 being for preventing foreign matters such as water, dust, etc. from entering the socket 3 through the insertion hole 300 as much as possible, the gasket 31 being provided with a slot 311 (see fig. 11) corresponding to the lower end of the upper link 23, the slot 311 being preferably cross-shaped; a socket box 32 arranged below the sealing gasket 31, wherein the bottom of the socket box 32 is provided with at least one guide part 321, each guide part 321 is sleeved with a lower connecting rod 33, the lower connecting rod 33 is sleeved with an elastic part 34 (shown in fig. 10), the upper end of the lower connecting rod 33 is provided with a water guide end part 331, the water guide end part 331 is optimally conical, and the lower end of the lower connecting rod 33 is provided with a limit clamping groove 332 formed by abrupt size change (enlargement or reduction); a limit part 35 provided below the guide part 321; and each lower connecting rod 33 is electrically connected with the control circuit board in the pot body 12 through the second lead 5.

In a typical embodiment: the plug 2 has 2 upper links 23 electrically separated from each other, and the socket 3 also has 2 lower links 33 electrically separated from each other, each upper link 23 being electrically connectable to one of the lower links 33, respectively.

In addition, the elastic portion 34 is preferably a spring, the upper end of which is limited to the water guiding end 331 of the lower link 33, and the lower end of which may be disposed to abut against the upper end of the guide portion 321, the lower end of the guide portion 321, or the stopper portion 35. When the plug 2 is separated from the receptacle 3, as shown in fig. 7, the upper end of the elastic portion 34 abuts against the lower side surface of the water guiding end portion 331, and the stopper groove 332 is also separated from the stopper portion 35.

The working principle of the joint switch is further described with reference to fig. 8 and 9. When the pot cover 13 is covered on the upper end face of the pot body 12, the upper connecting rod 23 passes through the slot hole 311 on the sealing pad 31 from the jack 300 of the socket panel 30, contacts with the upper end face of the water guide end 331 at the upper end of the lower connecting rod 33, and applies downward force to the lower connecting rod 33, so that the lower connecting rod 33 moves downward until the limit clamping groove 332 abuts against the limit part 35, and at the moment, the lower end face of the plug fixing seat 21 of the plug 2 is just attached to the boss 121 of the pot body 12. During the downward movement of the lower link 33, the elastic portion 34 is compressed to generate an upward reaction force to the water guide end portion 331, which brings the upper end surface of the water guide end portion 331 into close contact with the lower end surface of the lower end of the upper link 23, thereby ensuring the reliability of the connection between the plug 2 and the receptacle 3. Conversely, when the pot cover 13 is separated from the pot body 12, the upper connecting rod 23 can be conveniently separated from the socket 3 along with the upward movement of the pot cover 13.

In addition, although the gasket 31 can substantially block water and foreign matters from entering the socket 3 through the insertion hole 300 during the use of the connector switch, the upper link 23 may still carry water or other liquid into the socket 3 through the slot 311 of the gasket 31 during the insertion of the plug 2 into the socket 3. To this end, the invention improves the receptacle 3 in two ways: the upper end of the lower connecting rod 33 is provided with a conical water guide end 331, the cross section of the water guide end 331 is far greater than that of the lower connecting rod 33 body, so that the liquid carried by the upper connecting rod 23 flows to the bottom of the socket box 32 through the water guide end 331 and cannot flow down all the way along the lower connecting rod 33; secondly, a drain groove 36 is further arranged at the bottom of the socket box 32, and the drain inlet position of the drain groove 36 is lower than the upper end surface of the guide part 321, so that water and other liquids can be smoothly discharged from the drain inlet through the drain groove 36, and the working reliability of the switch joint is further improved.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
