[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1 to Figure 5 A fruit and vegetable washing machine includes a door structure 1 and a tank body 2. The door structure 1 covers the tank body 2. The door structure 1 and the tank body 2 are sealed and self-locked through a sealing self-locking structure 3.

[0031] The door structure 1 includes an upper cover 11 and a lower cover 12, and the upper cover 11 is arranged above the lower cover 12. The upper cover 11 is in the shape of a plate, and a handle 111 is arranged on its upper surface so that the door structure 1 can be operated by grabbing the handle 111. The lower cover 12 includes a lower cover body 121 in the shape of a plate, and a support wall 122 extending upward is formed around the lower cover body 121, and a position near the support wall 122 around the lower cover body 121 protrudes upward to form an annular first accommodating groove 123. A position around the lower cover body 121 located inside the first accommodating groove 123 protrudes upward to form an annular water storage tank 124.

[0032] The tank body 2 includes a tank body 21 with an upper opening, and a flange 22 is formed by extending outwards for a certain distance at the top of the tank body 21. The periphery of the flange 22 is bent upward to form a fold 23. The upper cover 11 and the lower cover 12 are both located on the inner side of the fold 23, and the lower cover body 121 of the lower cover 12 is supported on the flange 22. The top surface of the flange 22 and the position corresponding to the water storage tank 124 form an inclined surface 222 that gradually slopes downward from the outside to the inside. The arrangement of the water storage tank 124 on the lower cover 12 allows the splashed water to enter the water storage tank 124 when the cleaning machine is working, and has a buffering effect, so that the water will not leak directly from the gap between the lower cover 12 and the tank body 2. At the same time, the design of the inclined surface 222 of the tank body 2 in contact with the water storage tank 124 facilitates the water in the water storage tank 124 to flow back into the tank body 2, so as to improve the sealing performance of the door body structure 1.

[0033] The flange 22 has a second annular receiving groove 221 that is protruded downward, and the first receiving groove 123 of the lower cover 12 corresponds to the second receiving groove 221 of the flange 22 .

[0034] The sealing self-locking structure 3 includes a self-locking claw assembly 31 , a push plate 32 , a return spring 33 and a compression rod 34 arranged in the first accommodating groove 123 , and a sealing ring 35 and a magnet 36 arranged in the second accommodating groove 221 .

[0035] The self-locking claw assembly 31 includes a first self-locking claw 311 and a second self-locking claw 312. The first self-locking claw 311 includes two first locking claw plates 3111 (preferably, integrally formed) arranged at an angle, and the space formed between the two first locking claw plates 3111 opens downward. The second self-locking claw 312 includes two second locking claw plates 3121 (preferably, integrally formed) arranged at an angle, and the space formed between the two second locking claw plates 3121 opens downward. The first self-locking claw 311 and the second self-locking claw 312 are arranged side by side in the horizontal direction, and the first locking claw plates 3111 and the second locking claw plates 3121 that are close to each other are hinged by the positioning pin shaft 313.

[0036] The end of the first locking claw plate 3111 of the first self-locking claw 311 away from the second self-locking claw 312 is formed with a first clamping portion 3112 extending toward the second self-locking claw 312, and the end of the second locking claw plate 3121 of the second self-locking claw 312 away from the first self-locking claw 311 is formed with a second clamping portion 3122 toward the first self-locking claw 311.

[0037] The push plate 32 is arranged above the self-locking claw assembly 31, and the positioning pin shaft 313 passes through the bottom of the push plate 32 to connect the two. The top surface of the push plate 32 is provided with the above-mentioned telescopic rod 34, and the outer periphery of the telescopic rod 34 is sleeved with a return spring 33, and the top end of the telescopic rod 34 is connected and fixed with the top surface of the first accommodating groove 123. The bottom end of the return spring 33 abuts against the top surface of the push plate 32, and the top end of the return spring 33 abuts against the top surface of the first accommodating groove 123. When self-locking, the return spring 33 remains in a compressed state, so that the push plate 32 maintains a tendency to move downward. The top surface of the push plate 32 is also provided with a positioning pin 321, and a positioning hole 125 is opened at a corresponding position on the top surface of the first accommodating groove 124 of the lower cover 12, so that the positioning pin 321 can be inserted into the positioning hole 125 for matching, thereby improving the self-locking performance.

[0038] The sealing ring 35 is annular and fits with the second accommodating groove 221. The position of the sealing ring 35 near the top is recessed inward from both sides to form a clamping groove 351. A locking head 352 is formed above the clamping groove 351. Both sides of the locking head 352 are arc-shaped protruding outward, corresponding to the first self-locking claw 311 and the second self-locking claw 312, respectively, so that the first self-locking claw 311 and the second self-locking claw 312 can slide from top to bottom into the clamping groove 351. By providing the clamping groove 351, in cooperation with the self-locking claw assembly 31, the sealing performance of the cleaning machine during operation can be improved.

[0039] The bottom of the sealing ring 35 has an upwardly protruding portion to form a slot 353, and the magnet 36 is at least partially inserted into the slot 353. A magnet box 361 is arranged around the magnet 36. A coil 37 is arranged around the magnet box 361. In this embodiment, the coil 37 is located around the second accommodating groove 221.

[0040] The sealing self-locking structure 3 also includes a counterweight block 38 disposed above the first accommodating groove 123, and a pressure sensor 39 disposed at the bottom of the flange 22. The counterweight block 38 increases the gravity of the door body mechanism 1, so that when the cleaning machine is working, the lower cover 12 can be as close to the tank body 2 as possible. The pressure sensor 39 is used to detect the pressure applied by the lower cover 12 on the tank body 2.

[0041] In order to ensure that the door structure 1 and the trough body 2 are stably self-locked, the sealing self-locking structure 3 includes two structures, which are respectively arranged on two opposite sides of the door structure 1 and are symmetrical.

[0042] When the fruit and vegetable cleaning machine is working, the coil 37 is energized and the magnet 36 moves upward under the action of the electromagnetic field generated by the coil 37, thereby driving the sealing ring 35 to move upward and gradually enter the first accommodating groove 123. When the sealing ring 35 contacts the push plate 32, the sealing ring 35 continues to move upward to push the hinged part of the first self-locking claw 311 and the second self-locking claw 312 upward, thereby driving the push plate 32 to move upward (in this process, the return spring 33 is compressed and the telescopic rod 34 is contracted), and the positioning pin shaft 313 moves upward accordingly, thereby driving the first self-locking claw 311 and the second self-locking claw 312 to rotate, and the first self-locking claw 311 and the second self-locking claw 312 are rotated. The ends of the claw 311 and the second self-locking claw 312 connected to the positioning pin shaft 313 are lifted up, and the ends away from the positioning pin shaft 313 are rotated downward so that the two ends are close to each other, so that the first self-locking claw 311 and the second self-locking claw 312 are closed, and the first clamping portion 3112 of the first locking claw plate 3111 and the second clamping portion 3122 of the second locking claw plate 3121 located on the outside are clamped into the clamping groove 351 of the sealing ring 35 to complete the sealing and self-locking. At this time, the positioning pin 321 on the push plate 32 is inserted into the positioning hole 125 of the lower cover 12, which can improve the self-locking performance of the fruit and vegetable washing machine. Figure 8 and Fig. 9In the above process, the counterweight 38 applies downward pressure to the door structure 1 on the slot body 2, and cooperates with the force of the magnet 36 in the electromagnetic field to ensure that the door structure 1 is always in contact with the slot body 2. The pressure sensor 39 detects the pressure applied by the door structure 1 to the slot body 2 in real time. If it is less than the preset value (indicating that the self-locking has not reached the setting), an alarm is issued through the control module of the fruit and vegetable washing machine.

[0043] When the fruit and vegetable washing machine finishes working, the coil 37 is energized (the current direction is opposite to that during washing), and the magnet 36 moves downward under the action of the electromagnetic field generated by the coil 37, thereby driving the sealing ring 35 to move downward, and the push plate 32 moves downward under the action of the restoring force of the reset spring 33, and the positioning pin shaft 313 moves downward accordingly, so that the first self-locking claw 311 and the second self-locking claw 312 open in the opposite direction, and the first locking claw plate 3111 and the second locking claw plate 3121 located on the outside withdraw from the clamping groove 351 of the sealing ring 35, and the sealing ring 35 leaves the first accommodating groove 124 of the door body structure 1 and returns to the second accommodating groove 221 of the slot body 2, releasing the seal and self-locking, so that the user can remove the door body structure 1 conveniently, see Figure 6 and Figure 7 .
