Description

Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, and in particular to a disinfection device for irradiation sterilization. Background Technology

[0002] Irradiation sterilization equipment is a specialized device that uses ionizing radiation, such as ultraviolet rays and X-rays, to sterilize and disinfect items. Its core function is to destroy the nucleic acid structure of microorganisms through radiation energy, thereby achieving sterilization.

[0003] When using irradiation sterilization equipment, the ultraviolet light generated by the ultraviolet lamp tube is mainly used to sterilize the items. However, dust and other impurities will adhere to the outer surface of the lamp tube. Excessive dust accumulation will cause the outer surface of the ultraviolet lamp tube to be blocked by dust and other impurities, which will reduce the irradiation efficiency of the ultraviolet lamp tube and reduce the sterilization efficiency of the irradiation sterilization equipment. Utility Model Content

[0004] This invention addresses the problem that dust and other impurities adhere to the outer surface of the lamp tube, obscuring the outer surface of the ultraviolet lamp tube and thus reducing the irradiation efficiency of the ultraviolet lamp tube, which in turn reduces the disinfection efficiency of the irradiation disinfection equipment. Therefore, this invention provides an irradiation sterilization device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a disinfection device for irradiation sterilization, comprising a housing, a conveyor belt disposed inside the housing, a drive assembly disposed on one side of the housing, the drive assembly being capable of driving the conveyor belt to rotate inside the housing, a base mounted on the bottom of the housing, an irradiation chamber mounted in the middle of the top of the housing, ultraviolet lamps being evenly mounted on the top and both sides of the inner wall of the irradiation chamber, and a cleaning device disposed on the outer surface of several ultraviolet lamps, the cleaning device moving and cleaning the outer surface of several ultraviolet lamps by means of a U-shaped frame with a sponge board.

[0006] The effect achieved by the above components is as follows: by setting up a U-shaped frame with a sponge board, the U-shaped frame can be adjusted to move inside the irradiation chamber. When the U-shaped frame moves, it will drive the sponge board to move the outer surface of the ultraviolet lamp tube. When the sponge board moves, it will clean the outer surface of the ultraviolet lamp tube, so that impurities on the outer surface of the ultraviolet lamp tube are removed from the ultraviolet lamp tube. This helps to prevent dust and other impurities from blocking the ultraviolet lamp tube, and helps to prevent the irradiation efficiency of the ultraviolet lamp tube from decreasing, which would lead to a decrease in the disinfection efficiency of the irradiation disinfection equipment.

[0007] Preferably, the U-shaped frame is disposed inside the irradiation chamber, and the U-shaped frame is slidably installed on the top of the inner wall of the irradiation chamber. Sponge boards are fixedly installed on the top and both sides of the U-shaped frame. A wire is fixedly installed in the middle of one side of the U-shaped frame. An auxiliary frame is fixedly installed on one side of the irradiation chamber. A wire wheel is rotatably installed on the inner wall of the auxiliary frame through a bearing. One end of the wire is fixedly installed on the outer surface of the wire wheel.

[0008] The effect achieved by the above components is as follows: by setting up the spool, when the spool is rotated, the spool is wound around the outer surface of the spool, the spool will stretch the U-shaped frame, the U-shaped frame will drive the sponge plate to move, so that the sponge plate comes into contact with the ultraviolet lamp tube and moves on the outer surface of the ultraviolet lamp tube, thereby cleaning the impurities on the outer surface of the ultraviolet lamp tube.

[0009] Preferably, the horizontal cross-section of the sponge board is an isosceles trapezoid.

[0010] The effect achieved by the above components is as follows: by setting a sponge board with an isosceles trapezoidal cross section, both sides of the sponge board are inclined, which makes it easier for the sponge board to come into contact with and detach from the ultraviolet lamp when the U-shaped frame moves, and makes it easier to clean impurities on the outer surface of the ultraviolet lamp.

[0011] Preferably, rollers are rotatably mounted on the bottom of the U-shaped frame on the side closest to each other, and the outer surface of the rollers abuts against the outer surface of the conveyor belt.

[0012] The effect achieved by the above components is that by setting rollers, the rollers abut against the conveyor belt, which can support the U-shaped frame. At the same time, the friction of the rollers rolling on the conveyor belt is small, so they will not obstruct the movement of the U-shaped frame.

[0013] Preferably, springs are symmetrically fixedly installed on the top of one side of the U-shaped frame, and one end of the springs is fixedly installed on one side of the irradiation chamber.

[0014] The effect achieved by the above components is as follows: when the spool drives the spool to stretch the U-shaped frame, the U-shaped frame will compress the spring, causing the spring to deform. When the spool is rotated in the opposite direction, the spool will loosen on the outer surface of the spool, and the spring will reset, causing the U-shaped frame to move away from the spool until the U-shaped frame reaches one end of the ultraviolet lamp tube. This ensures that the spool is always taut throughout the process, which facilitates repeated cleaning of the outer surface of the ultraviolet lamp tube through the U-shaped frame.

[0015] Preferably, the spring has a round rod inside, with both ends of the round rod fixedly installed on both sides of the irradiation chamber, and the U-shaped frame is slidably installed on the outer surface of the two round rods.

[0016] The effect achieved by the above components is that by setting the round rod, the round rod can limit and guide the U-shaped frame and the spring, making the U-shaped frame more stable during movement, and at the same time helping to prevent the spring from bending during deformation.

[0017] Preferably, handwheels are rotatably mounted on both sides of the auxiliary frame, one end of the handwheel passes through one side of the auxiliary frame and is fixedly connected to one side of the reel, and the outer surface of the handwheel is provided with protrusions.

[0018] The effect achieved by the above components is as follows: by setting a handwheel, turning the handwheel can drive the thread wheel to rotate. At the same time, the outer surface of the handwheel is provided with protrusions, which can effectively increase the friction of the outer surface of the handwheel and have an anti-slip effect when turning the handwheel.

[0019] Preferably, a threaded pin is fixedly installed on one side of the handwheel, and round hole plates are provided on both sides of the handwheel. One end of the two round hole plates is symmetrically fixedly installed on the top of the inner wall of the irradiation chamber. The threaded pin is inserted into the inner wall of the round hole plate. Nuts are provided on the opposite sides of the two round hole plates, and the nuts are threadedly connected to the outer surface of the threaded pin.

[0020] The effect achieved by the above components is as follows: when the nut is rotated, the nut will move on the outer surface of the threaded pin, so that one side of the nut presses against the round hole plate until one side of the round hole plate is completely in contact with one side of the handwheel. Then the two round hole plates can fix the threaded wheels connected to the two handwheels. In turn, under the joint action of the spring, the U-shaped frame can be fixed in the designated position, which helps to prevent the U-shaped frame from shifting under the action of external force and blocking the ultraviolet lamp tube.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a U-shaped frame with a sponge board is installed. The U-shaped frame is adjusted to move inside the irradiation chamber. When the U-shaped frame moves, it causes the sponge board to move against the outer surface of the ultraviolet lamp tube. The sponge board cleans the outer surface of the ultraviolet lamp tube, removing impurities from the ultraviolet lamp tube. This helps prevent dust and other impurities from obscuring the ultraviolet lamp tube and thus prevents a decrease in the irradiation efficiency of the ultraviolet lamp tube, which would otherwise reduce the disinfection efficiency of the irradiation disinfection equipment.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] In the accompanying drawings of this embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0030] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] In this embodiment:

[0032] Reference Figure 1 The diagram shows a preferred embodiment of the present invention.

[0033] Reference Figures 1-3As shown, this embodiment discloses a sterilization device for irradiation, including a housing 1. A conveyor belt 2 is installed inside the housing 1. A drive assembly 3 is installed on one side of the housing 1, which drives the conveyor belt 2 to rotate inside the housing 1. (The drive assembly 3 can be a motor mounted on the housing 1 and two rollers on the inner wall of the conveyor belt 2. The motor is connected to one of the rollers via a reducer, and a power supply module powers the motor, driving one roller to rotate. This roller, in turn, drives the other roller and the conveyor belt 2 to rotate. Since motor-driven conveyor belt rotation is a conventional technique, it will not be elaborated upon here.) A base 4 is installed at the bottom of the housing 1, and an irradiation chamber 5 is installed in the middle of the top of the housing 1. Ultraviolet lamps 6 are evenly installed on the top and sides of the inner wall of the irradiation chamber 5. (The type of ultraviolet lamp 6 is...) The lamps (which may be Uvtrojan ultraviolet lamps) are equipped with cleaning devices 7 on their outer surfaces. The cleaning devices 7 move and clean the outer surfaces of the ultraviolet lamps 6 via a U-shaped frame 71 with a sponge plate 72. The U-shaped frame 71 is adjusted to move inside the irradiation chamber 5. When the U-shaped frame 71 moves, it moves the sponge plate 72 to clean the outer surfaces of the ultraviolet lamps 6, removing impurities from the outer surfaces of the ultraviolet lamps 6. This helps prevent dust and other impurities from obscuring the ultraviolet lamps 6 and reduces the irradiation efficiency of the ultraviolet lamps 6, thus reducing the disinfection efficiency of the irradiation disinfection equipment.

[0034] Reference Figure 2 and Figure 3 As shown, a U-shaped frame 71 is installed inside the irradiation chamber 5. The U-shaped frame 71 is slidably mounted on the top of the inner wall of the irradiation chamber 5. Sponge plates 72 are fixedly installed on the top and both sides of the U-shaped frame 71. A wire body 73 is fixedly installed in the middle of one side of the U-shaped frame 71. An auxiliary frame 75 is fixedly installed on one side of the irradiation chamber 5. A wire reel 74 is rotatably mounted on the inner wall of the auxiliary frame 75 via bearings. One end of the wire body 73 is fixedly mounted on the outer surface of the wire reel 74. By setting the wire reel 74, when the wire reel 74 is rotated, the wire body 73 is wound around the outer surface of the wire reel 74, and the wire body 73 will be attached to the U-shaped frame. When the U-shaped frame 71 is stretched, it will move the sponge board 72, causing the sponge board 72 to come into contact with the ultraviolet lamp tube 6 and move on the outer surface of the ultraviolet lamp tube 6, thereby cleaning the impurities on the outer surface of the ultraviolet lamp tube 6. The horizontal cross-section of the sponge board 72 is an isosceles trapezoid. By setting the sponge board 72 with an isosceles trapezoidal cross-section, both sides of the sponge board 72 are inclined, which makes it easier for the sponge board 72 to come into contact with and detach from the ultraviolet lamp tube 6 when the U-shaped frame 71 moves, and makes it easier to clean the impurities on the outer surface of the ultraviolet lamp tube 6.

[0035] Reference Figure 2 and Figure 3 As shown, rollers 76 are rotatably mounted on the bottom of the U-shaped frame 71 on one side. The outer surface of the rollers 76 abuts against the outer surface of the conveyor belt 2. By setting the rollers 76 and abutting against the conveyor belt 2, the rollers 76 can support the U-shaped frame 71. At the same time, the friction of the rollers 76 rolling on the conveyor belt 2 is small, so it will not obstruct the movement of the U-shaped frame 71. Springs 77 are symmetrically fixedly installed on the top of one side of the U-shaped frame 71. One end of the spring 77 is fixedly installed on one side of the irradiation chamber 5. The wire wheel 74 drives the wire body 73 to... When the U-shaped frame 71 is stretched, it compresses the spring 77, causing the spring 77 to deform. When the spool 74 is rotated in the opposite direction, the spool 73 will loosen on the outer surface of the spool 74, and the spring 77 will reset. This will cause the U-shaped frame 71 to move away from the spool 74 until the U-shaped frame 71 reaches one end of the ultraviolet lamp tube 6. This ensures that the spool 73 is always taut throughout the process, making it easy to clean the outer surface of the ultraviolet lamp tube 6 repeatedly through the U-shaped frame 71.

[0036] Reference Figure 2 and Figure 4 As shown, a round rod 78 is provided inside the spring 77. The two ends of the round rod 78 are fixedly installed on both sides of the irradiation chamber 5. The U-shaped frame 71 is slidably installed on the outer surface of the two round rods 78. By setting the round rods 78, the round rods 78 can limit and guide the U-shaped frame 71 and the spring 77, making the U-shaped frame 71 more stable during movement, and at the same time helping to prevent the spring 77 from bending during deformation.

[0037] Reference Figure 2 and Figure 4As shown, handwheels 79 are rotatably mounted on both sides of the auxiliary frame 75. One end of the handwheel 79 passes through one side of the auxiliary frame 75 and is fixedly connected to one side of the reel 74. The outer surface of the handwheel 79 has protrusions. By setting the handwheel 79, rotating the handwheel 79 can drive the reel 74 to rotate. At the same time, the protrusions on the outer surface of the handwheel 79 can effectively increase the friction of the outer surface of the handwheel 79, providing an anti-slip effect when rotating the handwheel 79. A threaded pin 711 is fixedly installed on one side of the handwheel 79. Circular perforated plates 710 are provided on both sides of the handwheel 79. One end of the two circular perforated plates 710 is symmetrically fixedly installed on the top of the inner wall of the irradiation chamber 5. The threaded pin 711 is inserted into the circular perforated plates. On the inner wall of 710, nuts 712 are provided on the opposite sides of the two circular plates 710. The nuts 712 are threadedly connected to the outer surface of the threaded pin 711. When the nuts 712 are rotated, they will move on the outer surface of the threaded pin 711, causing one side of the nuts 712 to press against the circular plates 710 until one side of the circular plates 710 is fully in contact with one side of the handwheel 79. Then, the two circular plates 710 can fix the threaded wheels 74 connected to the two handwheels 79. In turn, under the joint action of the spring 77, the U-shaped frame 71 can be fixed in the designated position, which helps to prevent the U-shaped frame 71 from shifting under the action of external force and blocking the ultraviolet lamp tube 6.

[0038] Working principle: Turning handwheel 79 causes the thread wheel 74 to rotate. As the thread wheel 74 rotates, the thread 73 wraps around its outer surface. The thread 73 stretches the U-shaped frame 71, which in turn compresses the spring 77, causing it to deform. Simultaneously, the U-shaped frame 71 moves the roller 76 against the outer surface of the conveyor belt 2 and the sponge plate 72, bringing it into contact with the ultraviolet lamp 6 and moving it along its outer surface until the thread 73 is completely wrapped around the outer surface of the thread wheel 74. Turning handwheel 79 in the opposite direction then loosens the thread 73 from the outer surface of the thread wheel 74, causing the spring 77 to reset and move the U-shaped frame 71 away from the thread wheel 74. Move in direction 4 until the U-shaped frame 71 reaches one end of the ultraviolet lamp tube 6. This keeps the line 73 taut throughout the process. Repeat the above operation, and the sponge plate 72 will clean the outer surface of the ultraviolet lamp tube 6 in a cycle. Rotate the nut 712, and the nut 712 will move on the outer surface of the threaded pin 711, so that one side of the nut 712 presses against the round hole plate 710 until one side of the round hole plate 710 is fully in contact with one side of the handwheel 79. Then the two round hole plates 710 can fix the line wheel 74 connected to the two handwheels 79. Then, under the joint action of the spring 77, the U-shaped frame 71 can be fixed in the designated position, which helps to prevent the U-shaped frame 71 from shifting under the action of external force and blocking the ultraviolet lamp tube 6.

[0039] It should be noted that the intermittent motion of the rotating and stopping conveyor belt 2 is a conventional technical method, so it will not be elaborated on here.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
