[0002] The traditional self-service fast food model in the catering industry is to place the cooked dishes on a tray on the self-service table for diners to choose and eat. The traditional self-service fast food model has many advantages: 1. There are many styles of dishes and they are rich in nutrition; 2. The diners decide whether to eat more or less, and they can choose more if they eat more, and they can choose less if they eat less; 3. Diners can eat as soon as they arrive, without waiting, saving dining time; 4. The dishes are prepared about 30 minutes in advance, so there is no problem of being hot just out of the pot; 5. The dishes are selected by diners and put on the plates, and the restaurant service staff does not need to pack the dishes, saving labor. However, the traditional self-service fast food model has a fatal disadvantage: it is very unhygienic. The prepared dishes are placed on the self-service table and are all exposed to the air. The dust in the air and foreign splashes will fall on the dishes and pollute the dishes. In particular, when diners choose dishes, the diners' saliva and dust on their bodies will fall into the dishes, causing secondary pollution to the dishes. Summary of the invention

DETAILED DESCRIPTION
[0039] The following is a further description of the improved scheme 1 of the present invention in conjunction with the accompanying drawings and embodiments:
[0040] Example 1: Hygienic fast food self-service station
[0041] like Figure 1 , Figure 2 As shown, a protective cover 2 is installed on the hygienic fast food self-service table. The protective cover 2 is composed of a 304 stainless steel frame and a glass surface. The glass is electrically heated glass with a demisting water function. The protective cover 2 is connected to a channel cover 1 through a hole. The channel cover 1 is made of food-grade nitrile (material for medical rubber gloves, a mature material on the market), which is thin, soft and elastic. The back of the protective cover 2 is composed of a glass window 10, which can be opened to facilitate the placement of trays 8-1 and dishes. Figure 6 As shown, the channel sleeve 1 is composed of two parts, the upper section is the handle sleeve 7, the shape of the handle sleeve 7 and the shape of the inner space correspond to the shape of the upper handle of the vegetable clip 4-1, the handle sleeve 7 is 1mm thick, the lower part is a truncated cone, the diameter of the upper bottom surface of the truncated cone is 120mm, the diameter of the lower bottom surface is 185mm, and the lower bottom edge protrudes outward to form a channel sleeve connecting edge 12, and the channel sleeve connecting edge 12 is evenly distributed with 6 screw holes, the top of the truncated cone is 1mm thick, the channel sleeve connecting edge 12 is 2mm thick, and the side of the truncated cone is 0.6mm thick. Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the top of the vegetable clip 4-1 is spherical, and the space inside the top of the grip sleeve 7 is also spherical. The size of the spherical space corresponds to the size of the spherical volume of the top of the vegetable clip 4-1. The top of the vegetable clip 4-1 is inserted into the top of the grip sleeve 7 (the grip sleeve has high elasticity), and the grip sleeve 7 tightly covers the handle of the vegetable clip 4-1. The middle of the lower part of the hook 5-1 is hollowed out, and the shape and size of the hollow space correspond to the shape and size of the top of the channel sleeve 1. The lower part of the hook 5-1 is divided into two halves, which are assembled together by screws and pins. The hook 5-1 is installed on the top of the channel sleeve 1 and is fastened to the top of the channel sleeve 1 and the top of the vegetable clip 4-1. Fig.10 , Fig.11 , Fig.12 As shown, the connection between the top of the channel sleeve 1 and the top of the vegetable clip 4-1 can also be connected by a screw fixing member. The top of the vegetable clip 4-1 is provided with a screw fixing member 20. The top surface of the channel sleeve 1 is made into a plane with a screw hole in the middle. The screw fixing member 20 passes through the screw hole on the top surface of the channel sleeve 1 and is fixed with a nut 21 with a hook. Fig. 9 As shown in the figure, the schematic diagram of the installation connection between the channel sleeve 1 and the hole interface on the protective cover 2 is shown. The screw hole on the channel sleeve connecting edge 12 at the bottom of the channel sleeve 1 is inserted into the stud 14 on the upper interface edge of the protective cover 2 below, and then the connecting pressure plate 13 is inserted on it, and the connecting nut 15 at the top is tightened, and the channel sleeve 1 is connected to the protective cover 2. Figure 1 , Figure 4 As shown, when no food is being picked up, the channel cover 1 and the food clip 4-1 are hooked on the suspension rod 6 above them through the hooking member 5-1 at the top thereof, and the channel cover 1 and the food clip 4-1 are suspended above the protective cover 2. Figure 2 As shown, when picking up food, the person holds the handle cover 7 on the channel cover 1, removes the hook 5-1 from the suspension rod 6, extends the food clip 4-1 into the protective cover 2, picks up the food on the tray 8-1 below, and puts it into the food box 9-1 below through the food outlet 11 between the front fast food self-service table and the front of the protective cover 2. After picking up the food, take out the channel cover 1 and the food clip 4-1 from the protective cover, and hook the hook 5-1 on the suspension rod 6. The channel cover 1 is thin, soft, elastic, and durable, and the food clip 4-1 can be flexibly moved over a large range and at multiple frequencies under the protective cover 2.
[0042] The protective cover 2 and the channel sleeve 1 fully cover the table top of the hygienic fast food self-service counter. The space enclosed by the protective cover 2 and the table top of the hygienic fast food self-service counter is connected to the outside only through the food outlet 11 at the front, and the food outlet 11 extends to the bottom of the table top of the hygienic fast food self-service counter. Dust, splashes, and diners' spit in the air are blocked outside the protective cover 2 and cannot fall on the dishes, thereby reliably ensuring the safety and hygiene of the dishes.
[0043] When hot dishes are placed on the hygienic fast food self-service table, water vapor will be generated in the protective cover 2. The water vapor contacts the glass surface of the protective cover 2 and forms small water droplets on the inner surface of the glass to form mist, which makes the glass surface of the protective cover 2 blurry. The dishes cannot be seen clearly from the outside, which is inconvenient for diners to choose and pick up dishes. The protective cover 2 is composed of electrically heated glass, which can prevent the formation of mist on the glass surface and ensure the transparency of the glass.
[0044] The method of using the hygienic fast food self-service table in this embodiment is as follows: the restaurant kitchen puts the fried dishes into the tray 8-1, pushes open the glass window 10 on the protective cover, puts the tray 5-1 on the table of the hygienic fast food self-service table, and then closes the glass window 10 until all the dish trays are placed on the table of the hygienic fast food self-service table. When the meal is ready, the diners take a look at the dishes, hold the handle cover on the channel cover 1 above the required dishes and the handle of the dish clip 4-1, take the channel cover 1 and the dish clip 4-1 off the suspension rod 6, reach into the protective cover 2, pick up the dishes on the tray 8-1 below, and put them into the dish box 9-1 below through the food outlet 11. After the dishes are picked up, take out the channel cover 1 and the dish clip 4-1, hang them on the suspension rod 6, and drag the dish box 9-1 to the front of other trays 8-1 with the left hand, then take off the channel cover 1 and the dish clip 4-1 from the top of other trays 8-1 with the right hand, and pick up other dishes. After the dishes are selected, take out the dish box 9-1 filled with dishes from the table below the food outlet 11, take the meal and pay.
[0045] Embodiment 1 The hygienic fast food self-selection station is also suitable for the self-selection and sale of cold dishes, which solves the hygienic problem of cold dishes that people have been worried about for a long time.
[0046] Embodiment 2: health soup pot
[0047] like Fig.13 , Fig.14 , Fig.19 As shown, the sanitary soup pot in this embodiment is mainly composed of a channel sleeve 1, a protective cover 2, a glass window 10 on the protective cover, a pot body 8-2, a soup ladle 4-2, a placing table 16, and a heating furnace 17. The overall shape of the protective cover 2 is a combination of two coaxial semi-cylinders of large and small, composed of a 304 stainless steel frame and an electric heating glass. The inner diameter of the inner ring frame 19 at the bottom of the cover is slightly larger than the diameter of the pot body 8-2. The inner ring frame 19 at the bottom of the protective cover 2 is inserted into the upper mouth of the pot body 8-2 and placed on the fixed edge 18 below the upper mouth of the pot body 8-2. Fig.13 , Fig. 20 , Fig.21 As shown, the protective cover 2 has a hole in the middle connected to a channel sleeve 1, and the upper section shape and inner space shape of the channel sleeve 1 correspond to the shape of the handle of the soup spoon 4-2, forming a grip sleeve 7. The channel sleeve 1 and the grip sleeve 7 thereon are made of the same material as in Example 1. The handle of the soup spoon 4-2 is placed in the grip sleeve 7. A hanging piece 5-2 is provided on the protective cover 2, and the grip sleeve 7 and the top of the handle of the soup spoon 4-2 are conveniently hung in the hanging piece 5-2. Fig. 22As shown, the channel sleeve 1 can also remove the upper section of the grip sleeve 7, and directly use the fixing ring 22 to fix the lower oblong cone channel sleeve to the lower end of the handle of the soup spoon 4-2, so that the human hand can directly hold the handle of the soup spoon 4-2. Fig.13 , Fig.14 , Fig.15 As shown, the right cylindrical surface of the protective cover 2 is composed of two glass windows 10, and the glass windows 10 can slide flexibly between the upper and lower inner ring frames 19 of the protective cover 2. When the two glass windows 10 are pushed to the left of the inner ring frame 19, the right side of the protective cover 2 is completely opened. Fig.13 , Fig.14 The left side of the inner ring frame 19 at the bottom of the protective cover 2 and the left side frame at the bottom of the protective cover 2 form a food outlet 11, and a placing table 16 is provided below the food outlet 11, and the placing table 16 is used to place the soup bowl 9-2. Fig.13 , Fig.16 As shown, when the two glass windows 10 are completely closed, the protective cover 2 and the channel sleeve 1 cover the upper opening of the pot body 8-2 in all directions, and the food outlet 11 is below the upper opening of the pot body 8-2, which reliably ensures that dust and splashes outside the protective cover 2 cannot enter the pot body 8-2, thereby ensuring the safety and hygiene of the soup.
[0048] The method of using the sanitary soup pot of this embodiment is explained in the self-selected fast food mode: Fig.15 As shown, in this state, the channel sleeve 1 and the soup spoon 4-2 are suspended above the protective cover 2, the two glass windows 10 are all pushed to the left side of the inner ring frame 19, and the right side of the protective cover 2 is fully opened. At this time, ingredients and water can be put into the pot body 8-2 to cook soup until the soup is cooked; Fig.13 As shown, after the soup is cooked, the two glass windows 10 are pulled out from the left side of the inner ring frame 19, and the two glass windows 10 are completely closed, waiting for the diners to arrive at meal time; Fig.16 As shown, when it is time to eat, the channel sleeve 1 and the soup spoon 4-2 are taken out from the hanging member 5-2, and the soup spoon 4-2 is put into the pot body 8-2 to prepare for the diners to scoop soup; Fig.16 , Fig.17 As shown, when the diner wants soup, the diner holds the grip cover 7 and the handle of the soup spoon 4-2, swings the soup spoon, scoops the soup from the pot body 8-2 to the top of the food outlet 11, and pours it into the soup bowl 9-2 below. After the soup bowl 9-2 is full of soup, the diner puts the soup spoon 4-2 into the pot body 8-2, and then takes the soup bowl filled with soup from the placing table 16.
[0049] Embodiment 2 The sanitary soup pot has a wide range of applications and can be used for supplying soup for sanitary self-service fast food, supplying nutritious soup for noodle soup, and supplying tea and sugar water.
[0050] The hygienic food protection cover of the present invention solves the "hygienic" problem of commercially sold food, which will bring about a revolution in the catering industry. The "hygienic fast food self-service station" model has core advantages:
[0051] 1. Clean and hygienic.
