[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0023] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0024] Reference Figures 1 to 5 The utility model proposes an automatic sealing structure for the bottom cover hole of a kitchen appliance, including a bottom cover assembly 2 and a push plate 3. The bottom cover assembly 2 is provided with a medium through hole 201. The push plate 3 is provided with a sealing member 5 for closing the medium through hole 201. An elastic member 4 capable of exerting a downward elastic force on the push plate 3 is connected between the push plate 3 and the bottom cover assembly 2. The push plate 3 is provided with an ejector pin 31 passing through the bottom cover assembly 2 downward. The lower end of the ejector pin 31 is lower than the lowest point of the lower surface of the bottom cover assembly 2. When the push plate 3 and the sealing member 5 move upward relative to the bottom cover assembly 2, the medium through hole 201 is opened. The above-mentioned sealing member 5 can be made of elastic materials such as ordinary rubber and silicone.

[0025] There are two methods for the ejector pin 31 to penetrate the bottom cover assembly 2. First, the bottom cover assembly 2 is also provided with a guide hole 202, and the ejector pin 31 penetrates the guide hole 202. Second, the diameter of the ejector pin 31 is smaller than the diameter of the medium through hole 201, and the ejector pin 31 directly passes through the middle of the medium through hole 201.

[0026] When the automatic sealing structure is applied to kitchen appliances such as soybean milk makers, wall breaking machines 1, kettles, health pots, milk mixers, instant hot water dispensers, etc., if these kitchen appliances are placed on a horizontal support surface such as a desktop, a kitchen countertop, or the ground, the horizontal support surface will push the ejector pin 31 upward, so that the lower end of the ejector pin 31 is flush with the lowest point of the bottom cover assembly 2. At this time, the push plate 3 and the seal 5 are pushed open, so that the medium through hole 201 is opened, which can be used for drainage, exhaust or air intake. When the soybean milk maker or wall breaking machine 1 is lifted, the push plate 3 and the seal 5 are reset downward under the elastic force of the elastic member 4, and the medium through hole 201 can be closed. At this time, the product can be maintained and cleaned without worrying about liquids such as tap water entering the product through the medium through hole 201.

[0027] In a preferred embodiment of the present invention, a guide hole 202 is further provided on the bottom cover assembly 2, and the ejector pin 31 passes through the guide hole 202. The seal 5 is in close contact with the lower surface of the push plate 3, and a through hole for the ejector pin 31 to pass through is provided in the middle of the seal 5. The lower surface of the seal 5 is provided with a waterproof rib 51, and the waterproof rib 51 is surrounded by a first rib ring 501 surrounding the medium through hole 201 and a second rib ring 502 surrounding the guide hole 202. The provision of the waterproof rib 51 can improve the sealing effect. In a preferred embodiment of the present invention, two hole groups are provided on the bottom cover, each hole group includes two medium through holes 201 and a guide hole 202 located between the two medium through holes 201, and the number of seals 5 is also two and corresponds to the hole group one by one. On each seal 5, the number of sealing plugs 52 is two, and the waterproof ribs 51 on the bottom surface of the sealing plug 52 are surrounded by a mesh-shaped structure. The middle part of the .-shaped structure is the second convex rib ring 502 , and the two ends of the .-shaped structure are the two first convex rib rings 501 .

[0028] As a further improvement of the above scheme, a sealing plug 52 for blocking the medium through hole 201 is provided on the lower surface of the sealing member 5. The provision of the sealing plug 52 can further improve the sealing performance. The bottom cover assembly 2 includes a bottom cover plate 21, a pressure plate 22 fixed on the top of the bottom cover plate 21, and a foot pad 23 provided on the lower surface of the bottom cover plate 21, and the lowest point of the foot pad 23 is the lowest point of the lower surface of the bottom cover assembly 2. The elastic member 4 includes a spring provided between the pressure plate 22 and the push plate 3. When the bottom cover assembly 2 is placed on a horizontal support surface such as a desktop, a kitchen countertop, or the ground, these horizontal support surfaces will push the ejector pin 31 upward, so that the push plate 3 and the sealing member 5 move upward relative to the bottom cover assembly 2, so that the sealing plug 52 is pulled out of the medium through hole 201 and the waterproof rib 51 is removed from the bottom cover plate 21. Specifically, a spring mounting column 221 is provided on the lower surface of the pressing plate 22, a positioning column 32 is provided on the upper surface of the pushing plate 3, the upper end of the spring is sleeved on the spring mounting column 221, and the lower end of the spring is sleeved on the positioning column 32. A support column 211 is provided on the upper surface of the bottom cover plate 21, and the pressing plate 22 is mounted on the support column 211 and is screwed to the support column 211.

[0029] In some solutions of the utility model, the elastic member 4 and the sealing member 5 may also adopt other structural forms. For example, the elastic member 4 adopts a tension spring, an elastic rope or the like, which is installed between the push plate 3 and the bottom cover plate 21, and pulls the push plate 3 downward by its own elastic force to keep the sealing member 5 in a sealed state. The sealing plug 52 is removed from the sealing member 5, and only the convex rib is used to pull and compress the seal.

[0030] Reference Figure 6When the medium through hole 201 is used as an exhaust hole or an air inlet, the above-mentioned convex rib can be eliminated, and the lower surface of the seal 5 is set on a plane. At the same time, a first annular platform 213 surrounding the medium through hole 201 and a second annular platform 214 surrounding the guide hole 202 are set on the upper surface of the bottom cover plate 21, and the seal 5 is pressed and sealed by the first annular platform 213 and the second annular platform 214.

[0031] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
