Description

Technical Field

[0001] The utility model relates to the field of food covers, in particular to a connection structure of an intelligent self-sensing food cover. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] As for the existing dining covers, they are widely used in buffet restaurants, canteens, Western-style family dinners, buffets, etc. The dining covers keep food warm, prevent dust and separate it from the outside air, and prevent food from being exposed to the air for a long time and causing pollution to the food. For this reason, a dining cover is added on the top of the buffet stove to keep the food warm and isolate it from the outside air. However, for conventional dining covers (which cannot be opened automatically), it will add a lot of trouble to diners. When taking food, they need to open the dining cover with a clip in one hand or pick it up and then put it down, so that they can take the dish with a free hand and then take the food in the buffet stove. After taking the food, they need to close or put it back. Once they forget to close it, the food will still be exposed to the air, which will still cause an impact.

[0004] For the existing buffet stove, an automatic cover function is added, specifically the Chinese utility model patent with patent application number 200820212075.6, named as automatic cover stove with sensor, this patent has the following disadvantages and shortcomings: first, because the cover is directly applied to the buffet stove and is integrated with the buffet stove, its application scene is limited. Second, because the device is integrated with the buffet stove, it is very inconvenient to clean and it is easy to have a sanitary dead corner.

[0005] However, the self-sensing dinner cover in this application has been improved to solve the above problems: 1. The dinner cover is separated from the dinner plate or dinner stove, etc. 2. The flipping method is improved. The rotation axis of the above patent document is parallel to the ground. When placed on the dinner plate, the flipping process will affect the stability of the dish and the dinner cover. Therefore, it is improved to have the rotation axis perpendicular to the ground. However, after the improvement, attention should be paid to the stability of the dinner cover during rotation to prevent the dinner cover from shaking during rotation. Utility Model Content

[0025] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0026] The utility model is a connection structure of an intelligent self-sensing dinner cover. As a whole, the self-sensing dinner cover can be used as an independent dinner cover and applied in multiple scenes. It can be placed on the top of a buffet stove or dinner plate to facilitate recycling and cleaning. It is convenient to use and can cover the food inside to prevent the food from being polluted by the external environment and the rapid changes in temperature and humidity that affect the taste of the food. A shell is provided on the top of the support cover 1. An infrared proximity sensor is provided obliquely in the shell. A transparent cover is provided obliquely in the shell. The sensor detects and identifies the distance of the human body through the transparent cover, thereby controlling the driving component 5 to drive the transparent cover 3 to rotate, and realizing the automatic opening and closing of the dinner cover.

[0027] As shown in the attached figure of the instruction manual Figure 2 and Figure 3 As shown, the main structure includes a support cover 1, a first bracket 2 arranged on the support cover 1, and a transparent cover 3 rotatably connected to the first bracket 2;

[0028] The support cover 1 is placed on the top surface of the container for holding dishes. The transparent cover 3 and the support cover 1 mainly play the role of shielding the food. The support cover 1 is made of stainless steel, and the transparent cover 3 can be set to acrylic or glass. A non-fogging coating can be added inside the transparent cover 3 to prevent the steam of the dishes from affecting the perspective effect of the transparent cover 3. The transparent cover 3 and the support cover 1 are surrounded to form a hemispherical structure, and the inner diameter of the support cover 1 is adapted to the outer diameter of the transparent cover 3. The curvature range of the transparent cover 3 needs to be adapted to the curvature range of the support cover 1, that is, the sum of the two needs to be greater than 360 degrees, so as to play the effect of shielding the food. In order to prevent the transparent cover 3 from affecting the clamping of food after opening, and to prevent a gap between the transparent cover 3 and the support cover 1, the curvature range of the transparent cover 3 is 182°-185°, and the curvature range of the support cover 1 is 180°.

[0029] A support edge 13 is provided at the bottom of the support cover 1, and the support edge 13 is used to increase the contact area between the device and the buffet stove or dinner plate, thereby increasing the stability of the device. For the device as a whole, in order to prevent the transparent cover 3 from contacting the container dining stove, the top surface of the dinner plate or the tabletop when rotating, and to control the temperature of the food inside the dinner cover, the bottom surface of the transparent cover 3 is 0.5-2mm higher than the bottom surface of the support edge 13, and it can also prevent flies, insects, dust, etc. from directly entering the dinner cover. Therefore, only the support cover 1 plays a supporting role. In order to further improve the balance and stability of the device, the range of the support edge 13 is greater than 185° and less than 205°, that is, the range of the support edge 13 is greater than half of the circumference of the support cover 1, thereby achieving better support and fixing effects, so that the device as a whole can be stably placed on the dinner stove or dinner plate. A first bracket 2 is provided on the support cover 1, and the first bracket 2 is used to connect the support cover 1 with the transparent cover 3. The following is the specific structure of the first bracket 2:

[0030] First bracket 2:

[0031] As shown in the attached figure of the instruction manual Figure 3 — Figure 5 As shown, the fixed cover 10 is connected with a first bracket 2, the first bracket 2 is provided with a mounting groove 4, an axial hole is reserved in the mounting groove 4, the axial hole is matched with the main shaft of the driving component 5, and the driving component 5 is arranged in the mounting groove 4, the driving component 5 is a reduction motor, and a sealing gasket 12 is provided between the mounting groove 4 and the bottom surface of the driving component 5. Because water vapor may enter the shell at the top of the support cover 1 from the gap between the first bracket 2 and the transparent cover 3 described below, in order to prevent water vapor from affecting the detection accuracy of the sensor, a sealing gasket 12 is provided to achieve sealing of the upper half to prevent water vapor from entering.

[0032] As shown in the attached figure of the instruction manual Figure 3As shown, the driving assembly 5 serves as a power element for the rotation process between the transparent cover 3 and the first bracket 2, wherein the rotation connection structure of the transparent cover 3 and the first bracket 2 is as follows: the transparent cover 3 is provided with a fixing groove 6, and a bearing 7 is provided between the fixing groove 6 and the outside of the first bracket 2, and the outer diameter of the bearing 7 is adapted to the inner diameter of the fixing groove 6. When the driving assembly 5 rotates, the transparent cover 3 is driven to rotate with the support cover 1 as the center of the circle. However, it is insufficient to rely solely on the fastening force of the interference fit between the fixing groove 6 and the bearing 7 to achieve the connection and fixing function with the first bracket 2, which is likely to cause the transparent cover 3 to fall off as a whole after the device is impacted. Therefore, a matching hole and a connecting groove 14 are provided at the bottom of the fixing groove 6, and the matching hole is matched with the main shaft of the driving assembly 5. A protrusion 8 is provided at the bottom of the matching hole. A retaining spring 9 is provided between the main shaft of the driving assembly 5 and the protrusion 8, and the relative fixation of the transparent cover 3 and the first bracket 2 is achieved by clamping the shaft groove on the main shaft by the retaining spring 9, thereby improving the stability of the transparent cover 3 during the rotation process.

[0033] As for the rotation process of the transparent cover 3 and the first bracket 2 on the support cover 1, since the overall shape of the transparent cover 3 is not a complete hemispherical shape, the force between the transparent cover 3 and the support cover 1 after opening and closing is not balanced, and the force is always biased to one side of the transparent cover 3. If there is a gap between the fixing groove 6 of the transparent cover 3 and the bearing 7 and the bottom surface of the first bracket 2, and there is a gap between the top surface of the transparent cover 3, the bearing 7 and the support cover 1, it is likely to affect the stability of the transparent cover 3 during the rotation process, so further improvement: as shown in the attached manual Figure 2 , Figure 5 and Figure 6 As shown, the bearing 7 is selected as a flange bearing 7, and a notch 11 adapted to the flange ring of the flange bearing 7 is provided on the transparent cover 3 and the first bracket 2. The flange ring of the flange bearing 7 limits the position between the transparent cover 3 and the first bracket 2, thereby improving the stability during the rotation process. If a bearing 7 without a flange is selected, not only will the above-mentioned problem occur, but it will also lead to too high a processing accuracy requirement for the fixing groove 6 of the transparent cover 3 and the first bracket 2, and it will be difficult to assemble during assembly, thereby increasing the production cost.

[0034] The fixed cover 10 outside the connection groove 14 is mainly used to fix the thermoelectric power generation sheet 15 set in the connection groove 14. The bottom surface of the thermoelectric power generation sheet 15 is in contact with the space surrounded by the transparent cover 3 and the support cover 1. The thermoelectric power generation sheet 15 uses the heating temperature of the cafeteria's insulation furnace and the steam temperature of the dishes to replenish the battery. This function can be added according to different scenarios. Taking the buffet restaurant and family dinner as examples, the usage frequency and usage time of the two scenarios are quite different. The buffet has a high flow of people and the usage frequency and time are high, while the family dinner has a short usage time with few people. Therefore, when using it in a buffet restaurant, it is necessary to consider the battery life of the device. By taking advantage of the fact that the buffet restaurant will set up a heating furnace or insulation furnace under the dishes, the battery life of the self-sensing dinner cover can be improved.

[0035] In summary, the device is used on the smart self-sensing dinner cover to drive and connect the two cover bodies, and can make the overall rotation process of the smart self-sensing dinner cover stable when opening and closing without shaking, and can also block the influence of steam generated by dishes on the sensor.
