The water-proof sheet 130 and the moisture-proof sheet 140 are both made of silicone material, which has good sealing performance and is durable in use; the water-proof sheet 130 is unfolded in an arc shape and is in sliding contact with the top edges and the outer edges of the two trays at the same time, and the moisture-proof sheet 140 is plate-shaped and is arranged between the tray placement port 101 and the tray discharge port 105, and is used to separate the washing and drying spaces in the cleaning box 100; a fixed plate column 240 is arranged at the center of the top surface of the rotating table 210, which is in sliding contact with the inner sides of the water-proof sheet 130 and the moisture-proof sheet 140, so as to form an all-round seal; thereby, the interior of the cleaning box 100 is divided into two closed spaces for washing and drying by the water-proof sheet 130, the moisture-proof sheet 140, the fixed plate column 240 and the tray.

[0037] Further, such as Figure 6 and Figure 7 As shown, a slide bar 102 is fixedly provided on the outer wall of the cleaning box 100 and located above and below the dish placement opening 101, and a slide cover 110 is slidably connected between a pair of slide bars 102. The cross section of the slide bar 102 is an inverted L-shape, so as to limit the slide cover 110; a silicone pad that is snap-fitted with the dish placement opening 101 is bonded to the inner wall of the slide cover 110 to play a sealing role.

[0038] It is worth mentioning that a self-opening cover 150 is hinged on one side of the dish outlet 105, the size of the self-opening cover 150 is larger than the size of the dish outlet 105, and a spring sheet 151 is sleeved on the middle part of the rotating shaft of the self-opening cover 150, and the two ends of the spring sheet 151 are respectively placed on the outer wall of the self-opening cover 150 and the cleaning box 100, and the self-opening cover 150 is squeezed by the elastic force of the spring sheet 151 to cover the outside of the dish outlet 105.

[0039] The top inner wall of the cleaning box 100 is provided with a ring platform 103 for supporting the water tank 310, and the guide ring 1031 is welded to the bottom of the ring platform 103 through a connecting strip; the side wall of the cleaning box 100 and the side of the heat dissipation cavity 311 are provided with a wiring hole 104 for passing the power line of the electric heating tube 312 to connect to the external power supply; the bottom of the cleaning box 100 is provided with a recovery box 120, the recovery box 120 is annular and its bottom surface is a conical surface with a downward convex middle part, and a recovery port 121 corresponding to the water leakage hole 221 is provided at the edge of the top surface of the recovery box 120, and a plurality of drainage ports 122 are provided at the bottom of the inner wall of the recovery box 120; so that the liquid in the annular groove flows into the recovery box 120 and then flows out from the plurality of drainage ports 122; the bottom center hole of the recovery box 120 is provided with a connector 123, and the bottom end of the connector 123 is provided with a water pipe, and the cleaned liquid can be discharged by leading the water pipe to the sewer.

[0040] Specifically, the cleaning section 300 includes a water tank 310 embedded in the top of the cleaning box 100, a plurality of spray parts 320 suspended at the bottom edge of the water tank 310, and a water pump installed inside the water tank 310 to pump liquid into the plurality of spray parts 320; a mixture of disinfectant and water is stored in the water tank 310; and the plurality of spray parts 320 are evenly spaced and distributed in the flushing space.

[0041] An electric heating pipe 312 is embedded in the water tank 310, and a heat dissipation cavity 311 is opened on one side of the water tank 310 and located in the drying space, and both ends of the electric heating pipe 312 extend into the heat dissipation cavity 311; the electric heating pipe 312 is energized to heat the liquid in the water tank 310, thereby increasing the cleaning and decontamination capabilities; at the same time, the part of the electric heating pipe 312 placed in the heat dissipation cavity 311 heats the other half of the space of the washing box 100, thereby drying the cleaned trays.

[0042] Furthermore, a plurality of water outlet pipes 313 are embedded at the bottom edge of the water tank 310 away from the heat dissipation cavity 311, and the output end of the water pump is connected to a pipe docking with the plurality of water outlet pipes 313; the spray cleaning part 320 includes a nozzle 321 movably sleeved with the water outlet pipe 313, and a plurality of nozzles 322 tangent to and connected with the side wall of the nozzle 321, at least every four nozzles 322 are distributed in a circular shape with equal intervals, and every four nozzles 322 form a group and are distributed in equal intervals along the axial direction of the nozzle 321, and the nozzle 322 is flat-mouthed and has an inner width of 1-2 mm; that is, the liquid pumped into the nozzle 321 is tangentially sprayed out through the plurality of nozzles 322 to wash the front and back of the tray that is constantly rotating.

[0043] Further, such as Figure 8-Figure 10As shown, the outer diameter of the rotating table 210 is smaller than the inner diameter of the supporting cover 220, thereby forming an annular groove for collecting liquid, and a plurality of leakage holes 221 are opened at the edge of the top surface of the supporting cover 220, so that the collected liquid leaks out of the cleaning box 100; the bottom of the spray pipe 321 extends to between the rotating table 210 and the supporting cover 220, and the bottom end of the spray pipe 321 is sleeved with a transmission gear 323, and the side wall of the rotating table 210 is sleeved with a gear ring 212 meshing with the transmission gear 323; that is, while the rotating table 210 drives a plurality of trays to pass through a plurality of spraying parts 320, the spray pipe 321 also rotates, and then the liquid sprayed from the nozzle 322 will be displaced and washed on the surface of the tray, thereby ensuring that the tray is fully washed.

[0044] Furthermore, the top surface of the rotating table 210 is conical and a fixed plate column 240 is vertically embedded in the center. The conical surface of the rotating table 210 is conducive to the flushing liquid flowing into the annular groove to avoid liquid accumulation; the fixed plate column 240 is a column with a large upper end and a small lower end, the slot 211 points to the central axis of the fixed plate column 240, and the slot 211 and the side wall of the fixed plate column 240 are vertically arranged, that is, the tray is placed in an inclined snap-fit ​​manner, so that the liquid on its surface is concentrated to flow toward the annular groove and gather.

[0045] Specifically, in order to allow the tray to be driven by the rotating table 210 to rotate for cleaning and drying and then be ejected out of the tray opening 105, a plurality of grooves 241 are provided in a circular shape at equal intervals on the middle outer wall of the fixed tray column 240. The plurality of grooves 241 correspond to the positions of the plurality of card slots 211 in a one-to-one manner. An elastic strip 250 is embedded in the groove 241, and sliding grooves 2411 are provided at the upper and lower ends of the groove 241.

[0046] The elastic strip 250 is made of stainless steel and has a V-shaped sheet structure. The elastic strip 250 is naturally V-shaped and bent at both ends. The elastic strip 250 is placed in the groove 241 and the bent section of the elastic strip 250 is plugged and moved with the slide groove 2411. The tray is inserted into the card slot 211 from the tray placement port 101 to squeeze the elastic strip 250 and smoothly expand it into the slide groove 2411, waiting for the rebound tray to pop out from the tray outlet 105.

[0047] Further, such as Figure 2-Figure 4As shown, in order to ensure that the tray is not ejected during the rinsing and drying process, a guide ring 1031 is suspended inside the top of the cleaning box 100 for limiting the tray to lean against the side wall of the fixed plate column 240. The guide ring 1031 is coaxially arranged with the cleaning box 100 and its inner diameter is equal to the outer diameter of the rotating table 210, so as to cooperate with the card slot 211 to limit the tray within the range directly above the rotating table 210, so as to avoid the tray from contacting and interfering with the cleaning part 300 when rotating; the guide ring 1031 is in a cut-off state at the tray placement port 101, the tray outlet 105 and the water-blocking sheet 130, so that the tray can be removed from the cleaning box 100. The tray enters from the tray placement opening 101 and is unloaded from the tray discharge opening 105; the guide ring 1031 is located at the end of the tray placement opening 101 and is bent and extended toward the inner wall of the cleaning box 100 to be provided with an inclined guide section 1032, which is used to guide the top side wall of the tray to slide along it to the inner side of the guide ring 1031. Since the inner diameter of the guide ring 1031 is equal to the outer diameter of the rotating table 210, the guide ring 1031 limits the position of the tray to compress the elastic strip 250, so that when the tray rotates to the tray discharge opening 105 with the rotating table 210, the elastic strip 250 loses the limit of the guide ring 1031 and releases the elastic force, so that the tray is ejected from the tray discharge opening 105.

[0048] The inner side edge of the moisture-proof sheet 140 is provided with an avoidance opening 141 which is adapted to be snapped with the elastic strip 250. A sealing sheet 260 is bonded to the middle outer wall of the fixed plate column 240 and between each adjacent two elastic strips 250. The sealing sheet 260 is adapted to be snapped and penetrated with the avoidance opening 141 to prevent water from the flushing space from escaping into the drying space.

[0049] When the tray is inserted into the card slot 211 from the tray placement opening 101, the sliding cover 110 is closed until the elastic strip 250 is inserted into one side of the top of the tray, and the elastic strip 250 is squeezed toward the inner end of the groove 241, so that the limiting groove 251 and the clamping strip 243 are engaged and limited. At this time, the elastic strip 250 is compressed to clamp the tray; at the same time, the elastic ring 253 is squeezed to become a vertical long axis, thereby storing elastic potential energy; when taking out the tray, the tray is quickly pushed toward the inner end of the groove 241, so that the limiting groove 251 and the clamping strip 243 slide off and separate, and the tray is released. Under the action of the larger rebound force of the elastic ring 253, the elastic strip 250 is ejected out of the groove 241, thereby bouncing the tray to expose the tray placement opening 101, and then it can be taken away.

[0050] When used, the tray cleaning device applicable to the infectious department of the present invention comprises the following steps: S1, first open the tray placement opening 101, and stand the tray with its wide side facing downward and insert it into the slot 211 through the tray placement opening 101; S2, then start the servo motor 230 to drive the rotating table 210 to rotate, and at the same time start the servo motor 230 and the water pump and connect the electric heating pipe 312, the rotating table 210 is driven to rotate and drive a number of trays to rotate in the cleaning box 100, the top of the tray is guided by the inclined guide section 1032 to slide to the inner range of the guide ring 1031 and limit the position, and the bottom of the tray will also slide synchronously along the card slot 211, so that the tray automatically squeezes the elastic strip 250 to deform, and slides into the slide slot 2411, accumulating power and ready to go; S3, the tray is washed when it passes through the spray cleaning parts 320 as the rotating table 210 rotates, and then dried when it passes through the area below the heat dissipation cavity 311; S4, when the first tray placed in rotates with the rotating platform 210 to the tray outlet 105, the elastic strip 250 rebounds and the tray pushes the self-opening cover 150 from the tray outlet 105, and the tray is automatically unloaded; S5, stop the servo motor 230, then open the tray placement port 101 to continue to place additional trays; S6. Clean the trays according to steps S1-S5 until all trays are unloaded.
