Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments and features of the embodiments described below can be combined with each other without conflict.

Example (b):

as shown in fig. 1 to 9, the present embodiment provides a coupler assembly including an upper cover 1 and a base 2; an upper contact piece 3 is arranged in the upper cover 1 in a sealing way, and a lower contact piece 4 is arranged in the base 2 in a sealing way; the upper contact piece 3 is provided with a contact part 30 exposed out of the upper cover 1, and the contact part 30 is used for being in contact connection with the lower contact piece 4 when the upper cover 1 is inserted into the base 2; a first drainage channel 10 penetrating through the top and the circumferential side wall of the upper cover 1 is arranged in the upper cover 1, and the first drainage channel 10 and the upper contact 3 are arranged in a separated manner; the base 2 is provided with a second drain passage 20 penetrating the top and bottom thereof, and the second drain passage 20 and the lower contact 4 are spaced apart from each other.

The coupler assembly provided by the embodiment can be applied to electric cooking appliances such as an electric food warmer, and at this time, the upper cover 1 can be fixed on the pan cover, and as shown in fig. 10 and 11, the base 2 can be fixed on the handle 5 of the pan body. When the coupler assembly is not in a working state and signal transmission is not needed, as shown in fig. 1 and 2, the upper cover 1 and the base 2 can be placed on the top of the base 2, or the upper cover 1 can be separated from the base 2; when the coupler assembly enters a working state and needs to transmit signals, as shown in fig. 3, the upper cover 1 can be inserted into the base 2 under the pushing of external force, and at the moment, the upper contact piece 3 in the upper cover 1 is in contact connection with the lower contact piece 4 in the base 2, so that the signals can be transmitted. The upper contact element 3 and the lower contact element 4 are both conductive elements, and both the upper contact element 3 and the lower contact element 4 can be of a plate-like structure.

When the electric food warmer needs to be cleaned, the pan cover and the pan body need to be cleaned respectively, the upper cover 1 is separated from the base 2, and when the electric food warmer is cleaned, even if water flows into the upper cover 1, the water can be discharged to the outside along the first water discharge channel 10 in the upper cover 1 and cannot be accumulated in the upper cover 1; similarly, even if water flows into the base 2, the water is discharged to the outside along the second drainage channel 20 inside the base 2 without accumulating in the base 2. In addition, since the upper contact 3 is hermetically disposed in the upper cover 1, the upper contact 3 and the first drain passage 10 are spaced from each other, and the lower contact 4 is hermetically disposed in the base 2, and the lower contact 4 and the second drain passage 20 are spaced from each other, the cleaning water is not only easily drained to the outside along the first drain passage 10 and the second drain passage 20, but also is not easily accumulated on the peripheral sides of the upper contact 3 and the lower contact 4.

When the electric cooker is used again and the upper cover 1 is inserted into the base 2 again, a large amount of moisture is not accumulated inside the upper cover 1 and the base 2, and cleaning water is not accumulated on the peripheral sides of the upper contact piece 3 and the lower contact piece 4, so that moisture is not easily accumulated inside the coupler assembly, and a short circuit is not easily generated.

Compared with the prior art, the coupler assembly provided by the embodiment can collect and discharge water flowing into the upper cover 1 during cleaning through the first water drainage channel 10 in the upper cover 1, and can collect and discharge water flowing into the base 2 through the second water drainage channel 20 in the base 2, so that moisture accumulation in the upper cover 1 and the base 2 can be respectively prevented through the first water drainage channel 10 and the second water drainage channel 20, and the coupler assembly can prevent moisture from existing around the upper contact 3 and the lower contact 4 by sealing the upper contact 3 in the upper cover 1 and sealing the lower contact 4 in the base 2, so that moisture can be prevented from existing inside the coupler assembly when the upper cover 1 is plugged in the base 2, and short circuit of the coupler assembly is prevented.

As shown in fig. 2, 3 and 7, the base 2 is a hollow structure, and an opening for the upper cover 1 to pass through is formed at the top of the base 2, so that the upper cover 1 can be inserted into the base 2; be equipped with sealing member 21 between the top of base 2 and the bottom, sealing member 21 and the sealed setting of the inner wall sliding connection of base 2, and the bottom lateral wall of sealing member 21 and base 2 all is equipped with the through-hole that communicates with second drainage channel 20.

When the coupler assembly does not enter the working state, as shown in fig. 1 and fig. 2, the upper cover 1 can be located on the top of the base 2 but is not inserted into the base 2, as shown in fig. 2 and fig. 6, at this time, the sealing member 21 is located at the opening of the top of the base 2, which can shield the devices inside the base 2 and prevent the outside cleaning water from flooding into the base 2 to contact with the lower contact member 4. However, since the sealing member 21 is provided with a through hole communicating with the second drainage channel 20, the sealing member 21, which serves as a shield, can still allow the external cleaning water to enter the second drainage channel 20 and flow out of the base 2 through the second drainage channel 20.

When the coupler assembly enters a working state, as shown in fig. 3, the upper cover 1 is inserted into the base 2, and at this time, the sealing member 21 is pushed by the upper cover 1 to move toward the bottom of the base 2, so that the sealing member 21 and the inner wall of the base 2 form a slot capable of accommodating the upper cover 1, and at the same time, the sealing member 21 allows the lower contact member 4 to be exposed in the slot, and at this time, the upper contact member 3 in the upper cover 1 entering the slot can be in contact connection with the lower contact member 4. Since the coupler assembly is in the working state, the coupler assembly does not contact cleaning water, the second drainage channel 20 does not need to drain water, the sealing member 21 does not need to play a role in shielding, and even if the lower contact 4 is exposed in the slot, a short circuit phenomenon cannot occur.

It should be noted that when the sealing member 21 is moved to a position close to the bottom of the base 2, the length of the second drain passage 20 is shortened along with the movement of the sealing member 21, but the second drain passage 20 is still spaced apart from the lower contact 4.

As shown in fig. 2, 3 and 7, the sealing member 21 is a plate-shaped structure, and a supporting pipe 22 is connected to one side of the sealing member 21 facing the bottom of the base 2; the supporting pipe 22 is communicated with the through hole of the sealing member 21, and the supporting pipe 22 is slidably connected in the bottom through hole of the base 2, and the through hole of the sealing member 21 and the supporting pipe 22 form the second drainage passage 20.
