[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figures 1 to 4 As shown, a device for cleaning the interior of a clean bench described in an embodiment of the utility model comprises a clean bench body 1; a driving motor 11 is fixedly connected to the side wall of the clean bench body 1; a first bevel gear 12 is fixedly connected to the output end of the driving motor 11; a first pad 13 and a second pad 131 are fixedly connected to the bottom of the inner wall of the clean bench body 1; the first pad 13 and the second pad 131 are symmetrically arranged on both sides of the clean bench body 1; a screw rod 14 is rotatably connected to the side wall of the first pad 13; the end of the screw rod 14 away from the first pad 13 passes through the second pad 131, and is rotatably connected to the second pad 131; a second bevel gear 15 is fixedly connected to the end of the screw rod 14; the second bevel gear 15 and the first bevel gear 12 are meshed with each other; a guide rod 16 is fixedly connected to the bottom of the inner wall of the clean bench body 1; A first connecting plate 17 is connected to the middle part of the screw rod 14 through a ball screw nut pair; a second connecting plate 171 is slidably connected to the middle part of the guide rod 16; a fixing plate 18 is installed together at the bottom ends of the first connecting plate 17 and the second connecting plate 171; a cleaning sponge 19 is fixedly connected to the bottom of the fixing plate 18. During operation, when the clean bench is used and there is waste residue on the surface of the clean bench, the drive motor 11 is turned on to drive the screw rod 14 to rotate, so that the first connecting plate 17 slides on the screw rod 14, driving the cleaning sponge 19 located under the first connecting plate 17 to slide on the surface of the clean bench to clean up the residual impurities on the surface of the clean bench, wherein the guide rod 16 plays a guiding role, and reduces the corrosion of the clean bench by residual impurities by keeping the inner surface of the clean bench clean.

[0031] like Figure 5As shown, the cleaning sponge 19 is fixedly connected with an infusion tube 2; the infusion tube 2 passes through the wall of the fixed plate 18 and is fixedly connected to the fixed plate 18; a plurality of leakage holes 21 are provided in the middle part of the infusion tube 2 near the lower part. During operation, by providing the infusion tube 2 inside the cleaning sponge 19, when cleaning the surface of the clean bench, disinfectant is poured into the infusion tube 2 so that the disinfectant is evenly distributed into the cleaning sponge 19 through the leakage holes 21. When the cleaning sponge 19 cleans the clean bench, the disinfectant absorbed by the cleaning sponge 19 can be smeared onto the inner surface of the clean bench, thereby achieving a disinfection effect on the inner surface of the clean bench and reducing the impact of bacterial growth on the use of the clean bench.

[0032] like Figure 4 and Figure 7 As shown, the first connecting plate 17 and the second connecting plate 171 are both slidably connected with a slider 3 in the middle; a pair of clamping blocks 31 are symmetrically arranged on the side walls of the slider 3; the clamping blocks 31 are L-shaped. During operation, when the cleaning sponge 19 is used many times, the cleaning effect may deteriorate or be damaged. At this time, the staff lifts the slider 3 from the first connecting plate 17 and the second connecting plate 171, so that the clamping blocks 31 in the clamping state of the fixed plate 18 are detached from the fixed plate 18, and then the fixed plate 18 is replaced, and the new fixed plate 18 is placed under the slider 3, and the slider 3 is lowered so that the pair of clamping blocks 31 on the slider 3 are engaged with the two sides of the fixed plate 18, and the fixed plate 18 continues to be clamped and fixed, thereby realizing the convenient replacement of the cleaning sponge 19 and improving the cleaning effect of the cleaning sponge 19.

[0033] like Figure 6 As shown, a fixing frame 4 is fixedly connected to the side wall of the clean bench body 1; the fixing frame 4 is located above the fixing plate 18; a fixing rod 41 is rotatably connected to the middle part of the fixing frame 4; a fan 43 is fixedly connected to the end of the fixing rod 41; a reel 42 is fixedly connected to the other end of the fixing frame 4; a connecting rope 44 is fixedly connected between the middle part of the reel 42 and the side wall of the fixing plate 18. During operation, when the fixing plate 18 moves on the inner surface of the clean bench driven by the first connecting plate 17, the fixing plate 18 pulls the connecting rope 44 to drive the reel 42 to rotate through the connection of the connecting rope 44, thereby causing the fan 43 located at the other end of the fixing rod 41 to rotate, and the air flow above the inner surface of the clean bench is accelerated by the fan 43, so that the cleaning residual disinfectant can evaporate faster, thereby reducing the liquid residue on the inner surface of the clean bench.

[0034] like Figure 2 and Figure 6As shown, a pair of support frames 5 are fixedly connected to the side walls of the clean bench body 1; a rotating rod 51 is fixedly connected between the pair of support frames 5; a roller 52 is rotatably connected to the middle of the rotating rod 51. When working, the connecting rope 44 is passed through the roller 52 to connect with the fixed plate 18, so that when the fixed plate 18 pulls the connecting rope 44, the sliding friction between the connecting rope 44 and the edges of the device can be reduced, the possibility of the connecting rope 44 being worn and broken is reduced, and the service life and safety of the connecting rope 44 are improved.

[0035] like Figure 6 As shown, a groove 6 is provided in the middle of the roller 52; the connecting rope 44 is located inside the groove 6 when passing through the roller 52. During operation, by placing the connecting rope 44 inside the groove 6, the possibility of the connecting rope 44 falling off the roller 52 can be reduced, thereby achieving a limiting effect on the connecting rope 44 and improving the stability of the connecting rope 44 during operation.

[0036] like Figure 7 As shown, a rubber pad 7 is fixedly connected to the clamp block 31; the rubber pad 7 is arranged on the inner wall of the clamp block 31 close to the slider 3. When working, by arranging the rubber pad 7 on the clamp block 31, the friction force exerted on the fixed plate 18 can be increased when the clamp block 31 clamps the fixed plate 18, thereby improving the fixing effect of the clamp block 31 on the fixed plate 18 and reducing the possibility of the fixed plate 18 falling off from the clamp block 31 during the movement.

[0037] like Figure 7 As shown, the side wall of the clamp block 31 is provided with a plurality of groups of anti-skid grooves 8; the anti-skid grooves 8 are located on the side wall of the clamp block 31 away from the slider 3. When working, by providing the anti-skid grooves 8 on the clamp block 31, the slider 3 can be slid upward by holding the clamp block 31, thereby increasing the friction between the clamp block 31 and the hand and reducing the possibility of falling off.

[0038] like Figure 5 As shown, a protective cover 9 is hinged on the top of the fixing plate 18; the protective cover 9 is sleeved on the end of the infusion tube 2. When working, the protective cover 9 covers the port of the infusion tube 2 to reduce the corrosion of the infusion tube 2 caused by dust falling into the infusion tube 2, and at the same time reduce the volatilization of the disinfectant in the infusion tube 2.

[0039] like Figure 6 As shown, a torsion spring is installed at the connection between the fixing rod 41 and the fixing frame 4. During operation, by installing the torsion spring, when the fixing plate 18 is cleaned and moved to the original position, the reel 42 rewinds the connecting rope 44 under the action of the torsion spring, thereby achieving the effect of multiple uses.

[0040] During operation, when the clean bench has been used and there is waste residue on the surface of the clean bench, the drive motor 11 is turned on to drive the screw rod 14 to rotate, thereby causing the first connecting plate 17 to slide on the screw rod 14, driving the cleaning sponge 19 located below the first connecting plate 17 to slide on the surface of the clean bench to clean the residual impurities on the surface of the clean bench. By providing an infusion tube 2 inside the cleaning sponge 19, when cleaning the surface of the clean bench, disinfectant is poured into the infusion tube 2, so that the disinfectant is evenly distributed into the cleaning sponge 19 through the leakage hole 21, so that when the cleaning sponge 19 cleans the clean bench, the disinfectant absorbed by the cleaning sponge 19 can be discharged. The venom is smeared on the inner surface of the clean bench, thereby achieving the disinfection effect on the inner surface of the clean bench. When the cleaning sponge 19 is used many times, the cleaning effect will deteriorate or be damaged. At this time, the staff can lift the slider 3 from the first connecting plate 17 and the second connecting plate 171 to disengage the clamping block 31 in the clamping state of the fixed plate 18 from the fixed plate 18, and then replace the fixed plate 18, place the new fixed plate 18 under the slider 3, and slide the slider 3 down so that the pair of clamping blocks 31 on the slider 3 are engaged with the two sides of the fixed plate 18, and the fixed plate 18 continues to be clamped and fixed, so as to realize the convenient replacement of the cleaning sponge 19. When the fixed plate 18 is on the first connecting plate 1 7, when the clean bench moves on the inner surface of the clean bench, the fixed plate 18 pulls the connecting rope 44 through the connection of the connecting rope 44 to drive the reel 42 to rotate, thereby rotating the fan 43 at the other end of the fixed rod 41, and accelerating the air flow above the inner surface of the clean bench through the fan 43, so that the residual disinfectant can evaporate faster. By passing the connecting rope 44 through the roller 52 and connecting it to the fixed plate 18, the sliding friction between the connecting rope 44 and the edges of the device can be reduced when the fixed plate 18 pulls the connecting rope 44, and the possibility of the connecting rope 44 being worn and broken can be reduced. By placing the connecting rope 44 inside the groove 6, the connecting rope 44 can be reduced from the roller 52. The possibility of falling off is achieved by limiting the connection rope 44. By providing a rubber pad 7 on the clamp block 31, the friction force on the fixed plate 18 can be increased when the clamp block 31 clamps the fixed plate 18, thereby improving the fixing effect of the clamp block 31 on the fixed plate 18. By providing an anti-slip groove 8 on the clamp block 31, the clamp block 31 can be held when the slider 3 slides upward to increase the friction between the clamp block 31 and the hand. By covering the port of the infusion tube 2 with the protective cover 9, the corrosion of the infusion tube 2 caused by dust falling into the inside of the infusion tube 2 is reduced. By installing a torsion spring, when the fixed plate 18 is cleaned and moved to its original position, the reel 42 can rewind the connection rope 44 under the action of the torsion spring.
