Description

Technical Field

[0001] The utility model relates to the technical field of food processors, in particular to a waterproof mechanism and a food processor applying the same. Background Art

[0002] When processing food materials with a food processor, for example, when making soy milk with a soy milk machine, the soy milk may overflow from the cup mouth. When cleaning the soy milk machine, water easily enters the inside of the machine base from the ventilation opening of the machine base, causing the circuit board to short-circuit and resulting in damage to the machine. After retrieval, it is found that the Chinese patent document with the application number 202020450227.7 discloses a cooking machine. A wind guiding member is arranged in the machine shell of the cooking machine. When the wind guiding member is in the first position, the air inlet and the air outlet are opened. When the wind guiding member is in the second position, the air inlet and the air outlet are closed, so that the machine base of the cooking machine has a waterproof function during cleaning. However, during the actual cleaning process, a small amount of water still enters the machine base from the gaps between the air inlet and the air outlet and the wind guiding member, and the waterproof effect is not good. Summary of the Invention

[0025] Reference Figure 1 、 Figure 2 and Figure 3 and

[0026] The waterproof structure includes a housing 100, a baffle 200 and an elastic member 300 disposed inside the housing 100.

[0027] The housing 100 can be a rectangular frame, a circular frame or a frame of other shapes, and it can be the outer housing of the base of the food processor. The housing 100 includes a bottom cover 110 and side edges 120 surrounding the bottom cover 110. The bottom cover 110 and the side edges 120 can be integrally formed by injection molding, die casting, etc., or can also be connected by an assembly method. The bottom cover 110 is provided with a ventilation opening 111, and the ventilation opening 111 can be an air inlet or an air outlet.

[0028] The baffle 200 is slidably connected inside the housing 100 in the vertical direction. In a preferred embodiment, a guide plate 101 is provided inside the housing 100, and a guide hole 102 is opened on the guide plate 101. A guide post 201 is fixedly provided on the upper surface of the baffle 200, and the guide post 201 is slidably connected in the guide hole 102 to realize the slidable connection of the baffle 200 inside the housing 100. It can be understood that the baffle 200 can also be slidably connected to the housing 100 in other ways, which is not limited herein.

[0029] The projection of the baffle cover 200 on the bottom cover 110 covers the ventilation opening 111. The elastic member 300 applies an elastic force towards the ventilation opening 111 to the baffle cover 200. Without external force, the baffle cover 200 abuts against the ventilation opening 111 under the elastic force of the elastic member 300. There are support columns 202 on the bottom surface of the baffle cover 200, and the bottom cover 110 is provided with a through hole 112. The support columns 202 pass through the through hole and extend downward. When processing food, the food processor is placed on the workbench. Under the action of the workbench surface and the self-gravity of the food processor, the support columns 202 move vertically upward along the through hole 102, driving the baffle cover 200 away from the ventilation opening 111, allowing the external environment to exchange air flow with the inside of the housing 100 through the ventilation opening 111.

[0030] In order to prevent water from flowing into the housing through the gap between the baffle cover 200 and the ventilation opening 111 during cleaning, a first flexible seal 400 is provided between the baffle cover 200 and the ventilation opening 111. The first flexible seal 400 has a certain flexibility and can deform when subjected to external force. For example, the first flexible seal 400 can be made of rubber materials such as nitrile rubber, neoprene rubber, and silicone rubber. When the baffle cover 200 abuts against the ventilation opening 111 under the elastic force of the elastic member 300, the first flexible seal 400 is squeezed between the baffle cover 200 and the ventilation opening 111. Since the first flexible seal 400 can deform, an effective and reliable sealing plug can be formed between the baffle cover 200 and the ventilation opening 111, preventing water from entering the housing 100 through the gap between the baffle cover 200 and the ventilation opening 111 during cleaning.

[0031] In a preferred embodiment, the first flexible seal 400 is a rubber gasket, and the rubber gasket can be fixedly connected to the bottom surface of the baffle cover 200 by bonding. Of course, the first flexible seal 400 can also be fixedly connected to the bottom surface of the baffle cover 200 by other means. For example, in some other embodiments, the first flexible seal 400 is provided with insertion ribs 401, and the baffle cover 200 is provided with slot holes. The first flexible seal 400 is fixedly connected to the baffle cover 200 by clamping the insertion ribs 401 in the slot holes. To prevent the first flexible seal 400 from falling off the bottom surface of the baffle cover 200, the size of the insertion end of the insertion ribs 401 is slightly larger than the aperture of the slot hole.

[0032] In another embodiment, the first flexible seal 400 can also be a silicone gasket (not shown). The silicone gasket can be fixedly connected to the bottom surface of the baffle cover 200 or to the bottom cover 100. It can be understood that whether the silicone gasket is fixedly connected to the bottom surface of the baffle cover 200 or to the bottom cover 110, the silicone gasket should surround the ventilation opening 111 when the baffle cover 200 abuts against the ventilation opening 111.

[0033] In some embodiments, the cross-sectional area of the support column 202 gradually decreases from top to bottom. This setting enables the support column 202 to move upward more easily under the gravity of the food processor, preventing the support column 202 from being stuck by the through hole 112 and causing the ventilation opening 111 to be unable to open.

[0034] In the present application, the bottom cover 110 is provided with a boss 113, and the ventilation opening 111 is formed on the boss 113 to increase the distance between the ventilation opening 111 and the workbench surface, so that the food processor can smoothly exchange air flow with the outside during operation.

[0035] In the present application, a drain hole 114 is further provided near the boss 113 of the bottom cover 110, and the shielding cover 200 is provided with an extension portion 210. When the shielding cover 200 covers the ventilation opening 111, the extension portion 210 covers the drain hole 114. When the food processor is operating and the shielding cover 200 opens the ventilation opening 111, the extension portion 210 also opens the drain hole 114 simultaneously. If there is water in the housing 100, it will drain out through the drain hole 114, preventing water from remaining in the housing 100.

[0036] To prevent water from entering the housing through the gap between the drain hole 114 and the extension portion 210 during cleaning, a second flexible seal 211 is fixedly connected to the bottom surface of the extension portion 210. The structure of the second flexible seal 211 and its connection method to the extension portion 210 can refer to the first flexible seal 400 and will not be elaborated here.

[0037] It should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
