Description

Technical Field

[0001] This invention relates to the field of disinfection technology, and in particular to a dry ice spray cleaning and disinfection device. Background Technology

[0002] Dry ice is widely used in modern society due to its advantages such as good cold storage effect, no residue after heating, and environmental friendliness and non-toxicity. In particular, dry ice is used as the main component of cleaning machines. Its working principle is to spray dry ice particles from the dry ice cleaning machine onto the surface of the parts to be cleaned by high-pressure air. The physical reaction of temperature difference causes different substances to detach at different contraction rates, thereby cleaning the surface and achieving a fast, efficient, safe and energy-saving cleaning effect. Through combined operation, pre-cleaning is achieved: the combination of compressed air and enzyme solution generates a foam-type cleaning solution that covers the surface of the instrument, softening blood stains and inhibiting microorganisms; dry ice cleaning: the combination of compressed air and dry ice generates a bursting force to remove the contaminated foam cleaning agent from the surface of the instrument; disinfection: vaporized hydrogen peroxide is sprayed into the chamber for disinfection.

[0003] Existing tabletop dry ice cleaning and sterilizing devices either have a single function or achieve dry ice spraying and disinfectant spraying by adapting and adjusting multiple disinfection nozzle components with different functions. The latter approach involves a complex overall structure and high equipment manufacturing costs. The former, which uses a conventional single disinfection nozzle component for spraying, has a limited function. Therefore, we propose a dry ice spray cleaning and sterilizing device.

[0014] A method for using a dry ice spray cleaning and sterilizing device includes the following steps:

[0015] S100, Pre-treatment: Dry ice, clean water, disinfectant, and foam cleaner are manually poured into the dry ice crusher, clean water tank, foam cleaner tank, and disinfectant tank, respectively.

[0016] S200, Placement: The surgical and medical instruments are manually placed into the built-in disinfection and cleaning tank, and the transparent splash guard is closed.

[0017] S300, Level 1 Adjustment: Manually insert rubber protective gloves and manually rotate the adjustment turntable to lower the lifting adjustment frame, disengage the secondary bevel gear from the reciprocating toothed part, and engage the reciprocating toothed part with the input bevel gear and multi-stage bevel gear. Then, manually rotate the connecting threaded sleeve to separate the extrusion block from the force-bearing block.

[0018] S400, Pre-cleaning treatment: The foam cleaner in the foam cleaner tank is drawn in by a pump, and high-pressure air is delivered simultaneously by an air booster fan, so that the foam cleaner and high-pressure air are mixed and delivered to the central delivery pipe. Then, the drive rod is driven to rotate by a reciprocating drive motor, so that the drive base slides along the surface of the linear limit shaft. At the same time, the swing drive motor rotates to drive the reciprocating toothed part to drive the input bevel gear and multi-stage bevel gear to perform counter-transmission to form a reciprocating swing operation. At this time, one of the external spray holes coincides with the section groove A, so that the foam cleaner mixed with high-pressure air is evenly sprayed onto the surface of the surgical and medical instruments in the embedded disinfection and cleaning tank, and then returns to the initial position.

[0019] S500, Secondary Adjustment Processing: The lifting adjustment frame is raised by manually rotating the adjustment turntable through rubber protective gloves. The secondary bevel gear engages with the meshing cavity. Then, the extrusion block is squeezed and pressed against the force-bearing block by manually rotating the connecting threaded sleeve.

[0020] S600 Dry Ice Cleaning Process: The dry ice fed from above is pulverized by a dry ice pulverizer, and high-pressure air is simultaneously delivered by an air booster fan, causing the dry ice and high-pressure air to mix and be synchronously delivered to the central delivery pipe. Then, a reciprocating drive motor drives the drive rod to rotate, causing the drive base to slide along the surface of the linear limit shaft. At the same time, a swing drive motor rotates the secondary bevel gear, causing the outer adjustment pipe to rotate unidirectionally. At this time, several external spray holes coincide with the segment groove A in sequence. Simultaneously, the rotation of the outer pipe body synchronously drives the force-bearing shaft to rotate, causing the extrusion block to slide and extrude the peak force-bearing protrusion, thus moving and compressing the inner pipe body. The cavity space formed by the body and the inner wall of the central delivery tube, and based on the limiting cooperation of the extrusion groove and the rotating protrusion, causes the inner tube body to rotate synchronously during the compression process, causing the partition sealing block A and partition sealing block B to form a sealing effect. After continuous unidirectional rotation, the extrusion block slides to the peak point of the peak force protrusion, and the extrusion force gradually decreases. Under the action of the spring, the inner tube body returns to its original position, causing the partition sealing block A and partition sealing block B to overlap, so that the segment groove B and segment groove A are connected, and the connecting channel opens from small to large, effectively improving the initial stage pressure of the downward tilted dry ice spray, making it easier to maintain a good and stable impact bursting force to clean the surface of surgical and medical instruments. After the dry ice cleaning is completed;

[0021] S700, Flushing Treatment: Clean water is pumped in by a pump, and high-pressure air is simultaneously delivered by an air booster fan to rinse surgical and medical instruments;

[0022] S800 Drying process: The surgical and medical instruments are preheated and dried by electric heating through an embedded disinfection and cleaning tank.

[0023] S900, Disinfection Treatment: The pump delivers disinfectant and hydrogen peroxide solution into the embedded disinfection and cleaning tank for disinfection.

[0024] S1000, Suction Treatment: The negative pressure effect created by the fan suction draws the vaporized hydrogen peroxide in the embedded disinfection and cleaning tank from the long connecting tank to the outside by the fan.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. This invention utilizes a manually adjustable dual-mode angle adjustment structure for reciprocating oscillation, and manually adjusts the rotation of the following force structure to separate it from the internal pressure regulating component. The internal pressure regulating component, under the action of elastic force, maintains continuous communication with the interior of the central delivery tube. Driven by the dual-mode angle adjustment structure, it reciprocates downwardly pumping the sprayed foam cleaning agent, achieving a high degree of continuity while minimizing leakage to surgical instruments. In a unidirectional rotation adjustment operation, the manually adjusted dual-mode angle adjustment structure is used, and the following force structure rotates to contact and adhere to the internal pressure regulating component. This causes the internal pressure regulating component to rotate and slide, compressing and intermittently compressing the cavity formed between the internal pressure regulating component and the interior of the central delivery tube, creating a secondary pressurization effect. Therefore, in the unidirectional rotation state of the dual-mode angle adjustment structure, when the internal pressure regulating component is connected to the output end of the following force structure, the pressure of the dry ice in the initial connected state is effectively increased, facilitating... Figure 13 The tilted spray shown initially has relatively high pressure, which increases the impact and bursting force of the dry ice in contact with the foam stains, effectively improving the cleaning power of dry ice spray cleaning. Through the above two operation methods, the foam cleaner is adapted to continuous, efficient and full coverage contact, and the dry ice spray operation adapts to the spray distance changes caused by angle changes during actual operation, thus improving the cleaning effect of high-pressure dry ice spray operation.

[0027] 2. In this invention, an air booster fan serves as the primary power source, enabling the separate delivery of dry ice, foam cleaning agents, clean water, disinfectant, etc. The overall structure is as follows: Figure 11 As shown, the overall connection structure is compact and easy to control, making it effective and convenient to operate.

[0028] 3. In this invention, the dry ice storage box is positioned above the dry ice crusher to facilitate natural feeding for crushing operations; and the long connecting groove allows the fan to be activated when the transparent splash guard is closed to extract residual hydrogen peroxide gas from the embedded disinfection and cleaning tank for discharge, reducing the risk of operators inhaling excessively high concentrations of residual hydrogen peroxide gas by directly opening the transparent splash guard.

[0029] 4. This invention achieves the rotation of the drive rod by the unidirectional rotation of the reciprocating drive motor, and uses a linear limit shaft to limit the rotation of the dual-mode angle adjustment structure in the radial angle direction, causing the dual-mode angle adjustment structure to move linearly. At the same time, this method of operation does not require the reciprocating drive motor to adjust in both directions, thus optimizing the complexity of equipment operation.

[0030] 5. This invention enables the lifting and adjusting frame to move only up and down when it is limited by the lifting and adjusting adapter slot by manually rotating the adjustment turntable. During the descent operation, the reciprocating toothed part can intermittently engage with the outer adjusting tube to form an oscillating adjustment. During the ascent operation, the secondary bevel gear part continuously engages with the outer adjusting tube to form a unidirectional rotation adjustment. Through the above two operations, foam cleaning agent spraying operation is performed in a continuous reciprocating oscillating mode, and dry ice cleaning spraying operation is performed in a unidirectional rotation intermittent pressurized mode.

[0031] 6. This invention utilizes opposing input bevel gears, multi-stage bevel gears, and a dual-mode angle adjustment structure to achieve reciprocating toothed section meshing operation. This allows the outer tube body to perform intermittent opposing rotational motion during the unidirectional rotational motion of the reciprocating toothed section, creating a swinging effect. Through this swinging motion... Figure 13 The system demonstrates the operation of fully spraying foam cleaner into the embedded disinfection and cleaning tank. Based on a dual-mode angle adjustment structure, the reciprocating toothed portion of the adjustment mechanism separates, causing the secondary bevel gear to engage with the meshing cavity. The rotation of the secondary bevel gear drives the meshing cavity to continuously rotate the outer adjustment tube in one direction. This method allows for intermittent dry ice spraying, achieving efficient pressurization. Simultaneously, the meshing cavity, with its larger outer and smaller inner shape, reduces the space required for the secondary bevel gear's lifting and lowering movements, thus minimizing the overall size and manufacturing cost of the dual-mode disinfection and cleaning system.

[0032] 7. This invention, based on the central feeding pipe setup and the fixed, non-rotating operation, ensures that any external spray hole on the surface of the outer pipe body achieves communication when it coincides with the segment groove A, and achieves closure when misaligned. Simultaneously, the arc angle of the segment groove A is greater than the arc angle of the external spray hole to adapt to... Figure 13 The required spray range is shown.

[0033] 8. The present invention features a partition block B positioned at an offset position relative to the partition block A inside the segment groove B. This allows for relative sealing and pressure maintenance when the segment groove B overlaps with the segment groove A. Simultaneously, the spring force causes the inner tube body to expand and rotate along the rotating protrusion via a spiral extrusion groove, resulting in the partition block A overlapping with the partition block B. This connects the segment groove B and the segment groove A, with the connecting channel opening from small to large. This effectively increases the initial pressure of the downwardly sprayed dry ice, facilitating the maintenance of a good and stable impact bursting force.

[0034] 9. This invention uses manual rotation of the threaded sleeve to cause the locking block on the force-bearing shaft tube to slide linearly along the locking groove. Rotating the threaded sleeve allows the extrusion block to contact or move away from the force-bearing protrusion at the peak. Simultaneously... Figure 12 As shown, during the process of the compression block sliding from the peak point of the slope with a relatively large slope width to the valley point of the slope with a relatively large slope width, the compression protrusion at the peak is connected to the slope groove B and the slope groove A, and the sliding distance and time are adapted to the unfolding distance and time of the inner tube body by the spring. During the sliding process of the compression protrusion at the peak point from the valley point of the slope with a relatively small slope width to the peak point of the slope with a relatively large slope width, the smaller width effectively increases the sliding time of the compression block, accelerates the linear sliding of the compression block to push the inner tube body to spiral compression, and improves the compression ratio. In addition, the linear structure of the limiting groove and the limiting protrusion limits the sliding, avoiding the compression block from following the rotation and causing driving errors and motion interference.

[0058] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0059] Example 1: A dry ice spray cleaning and sterilizing device, see [link to example]. Figures 1 to 13The system includes a cabinet 1; an embedded disinfection and cleaning tank 2 is provided on the upper surface of the cabinet 1; the gap between the inner wall of the cabinet 1 and the outer wall of the embedded disinfection and cleaning tank 2 forms a multi-level operating chamber, and the embedded disinfection and cleaning tank 2 is an electrically heated structure; a multi-level cleaning component 5 is provided inside the multi-level operating chamber; and a dual-mode disinfection and cleaning system 6 is provided at the output end of the multi-level cleaning component 5; a transparent splash guard 3 is hinged to the outer wall of the cabinet 1 relative to the embedded disinfection and cleaning tank 2, and a perforation is provided on one side of the transparent splash guard 3. A perforated edge is fixedly fitted with a rubber protective glove; an operation panel assembly 4 is provided on one side of the transparent splash guard 3; the dual-mode disinfection and cleaning system 6 includes a reciprocating drive structure 7, a dual-mode angle adjustment structure 8, an external adjustment pipe 9, a central delivery pipe 10, an internal pressure regulating assembly 11, and a following force-adjusting structure 12; the reciprocating drive structure 7 is arranged in a multi-stage operating chamber, the dual-mode angle adjustment structure 8 is slidably arranged on the embedded disinfection and cleaning tank 2, the external adjustment pipe 9 is rotatably arranged on the dual-mode angle adjustment structure 8, and the central delivery pipe 10... The delivery pipe 10 is movably arranged inside the outer regulating pipe 9, and the inner pressure regulating component 11 is movably arranged inside the central delivery pipe 10. The following force-adjusting structure 12 is screwed to the end of the outer regulating pipe 9. The dual-mode angle adjustment structure 8 has a reciprocating swing state and a unidirectional rotation state. In the reciprocating swing state of the dual-mode angle adjustment structure 8, the following force-adjusting structure 12 rotates and separates from the inner pressure regulating component 11, so that the outside of the inner pressure regulating component 11 is continuously connected to the inside of the central delivery pipe 10. The outer regulating pipe 9 swings back and forth synchronously, causing one of the output ends of the outer regulating pipe 9 to connect with the output end of the central delivery pipe 10 to form a continuous reciprocating swing foam cleaning agent spraying structure. In the unidirectional rotation state of the dual-mode angle adjustment structure 8, the following force-adjusting structure 12 rotates and squeezes and adheres to the inner pressure regulating component 11, causing the outside of the inner pressure regulating component 11 to be intermittently connected to the inner wall of the central delivery pipe 10. The outer regulating pipe 9 rotates unidirectionally synchronously, causing several output ends of the outer regulating pipe 9 to be intermittently connected with the output end of the central delivery pipe 10 to form a pressurized dry ice cleaning spraying structure. This invention utilizes a manually adjustable dual-mode angle adjustment structure 8 for reciprocating oscillation, and a manually adjustable follower force structure 12 for rotational adjustment to separate from the internal pressure regulating component 11. The internal pressure regulating component 11 maintains continuous communication with the central delivery tube 10 under the action of elastic force. Driven by the dual-mode angle adjustment structure 8, it reciprocates downwardly tilting and pumping the sprayed foam cleaning agent, achieving a high degree of continuity while minimizing leakage to surgical instruments. In a unidirectional rotational adjustment operation using the dual-mode angle adjustment structure 8, the follower force structure 12 is manually adjusted to rotate and contact the internal pressure regulating component 11, causing the internal pressure regulating component 11 to rotate and slide, compressing and intermittently compressing the cavity formed between the internal pressure regulating component 11 and the central delivery tube 10, creating a secondary pressure boosting effect. This effectively increases the pressure of the dry ice in the initial state of connection when the internal pressure regulating component 11 is connected to the output end of the follower force structure 12, facilitating... Figure 13 The tilted spray shown initially has relatively high pressure, which increases the impact and bursting force of the dry ice in contact with the foam stains, effectively improving the cleaning power of dry ice spray cleaning. Through the above two operation methods, the foam cleaner is adapted to continuous, efficient and full coverage contact, and the dry ice spray operation adapts to the spray distance changes caused by angle changes during actual operation, thus improving the cleaning effect of high-pressure dry ice spray operation.

[0060] Specifically, the multi-stage cleaning component 5 includes an air booster fan 501, a wastewater tank 502, a blower 503, and a dry ice crusher 504.

Several branch pipes and solenoid valves connected to the branch pipes are installed on the pipe. The wastewater tank 502 is located on one side of the embedded disinfection and cleaning tank 2, and its output end is connected to the input end of the embedded disinfection and cleaning tank 2.

The invention comprises the following components: a blower 503 is arranged within a multi-stage operating chamber; a dry ice crusher 504 is arranged on the other side of the embedded disinfection and cleaning tank 2, and the output end of the dry ice crusher 504 is connected to one of the solenoid valves via a pipe; a clean water tank 505 is arranged below the embedded disinfection and cleaning tank 2, and a pump is installed at the output end of the clean water tank 505, with the pump output end connected to another solenoid valve via a pipe; a foam cleaner tank 506 is arranged on one side of the clean water tank 505, and a pump is installed at the output end of the foam cleaner tank 506, with the pump output end connected to another solenoid valve via a pipe. In this invention, the air booster blower 501 serves as a crucial power source, enabling the separate delivery of dry ice, foam cleaner, clean water, and disinfectant. The overall structure is as follows: Figure 11 As shown, the overall connection structure is compact and easy to control, making it effective and convenient to operate.

[0061] Furthermore, a dry ice storage tank 101 is provided in the cabinet 1 relative to the input end of the dry ice crusher 504, and the discharge end of the dry ice storage tank 101 is connected to the input end of the dry ice crusher 504; the inner wall of the embedded disinfection and cleaning tank 2 is provided with at least one elongated connecting groove 201 that communicates with the multi-stage operating chamber. In this invention, the dry ice storage tank 101 is positioned above the dry ice crusher 504 to facilitate natural discharge for crushing operations; and the elongated connecting groove 201 facilitates the activation of the fan 503 when the transparent splash guard 3 is closed to extract residual hydrogen peroxide gas from the embedded disinfection and cleaning tank 2 for discharge, reducing the risk of operators inhaling excessively high concentrations of residual hydrogen peroxide gas by directly opening the transparent splash guard 3.

[0062] Furthermore, the reciprocating drive structure 7 includes a drive rod 701 and linear limiting shafts 703. The drive rod 701 is arranged in the multi-stage operating cavity via a rotating seat, and a reciprocating drive motor 702 is provided at one end of the drive rod 701. The drive rod 701 has two symmetrically arranged threaded grooves on its surface, and the threaded grooves are connected end-to-end. The two linear limiting shafts 703 are arranged on one side of the outer wall of the embedded disinfection and cleaning tank 2 via mounting seats. This invention achieves the rotation of the drive rod 701 through the unidirectional rotation of the reciprocating drive motor 702, which, in conjunction with the linear limiting shafts 703, limits the radial angle of the dual-mode angle adjustment structure 8, causing the dual-mode angle adjustment structure 8 to move linearly. This method eliminates the need for forward and reverse adjustment by the reciprocating drive motor 702, thus optimizing the complexity of equipment operation.

[0063] It is worth noting that the dual-mode angle adjustment structure 8 includes a drive base 801, an adjustment turntable 802, a swing drive motor 803, a lifting adjustment frame 804, and an output gear shaft 805. The drive base 801 is slidably arranged on the elongated connecting groove 201, and the drive base 801 is slidably engaged with the linear limiting shaft 703. A drive block 8011, which meshes with a threaded groove, is rotatably arranged on the side of the drive base 801 closest to the drive rod 701. A plurality of rotating hook blocks 8012 are arranged in a ring at equal intervals on the upper surface of the drive base 801. The gaps between the inner walls of the plurality of rotating hook blocks 8012 form a lifting engagement adjustment cavity. At least two lifting adjustment adapter grooves 8013 are opened on the upper surface of the drive base 801. The adjustment turntable 802 is rotatably arranged within the lifting engagement adjustment cavity. The swing drive motor 803... The mounting base is arranged on the drive base 801, and the output of the swing drive motor 803 is provided with a key shaft sleeve 8031, wherein the key shaft sleeve 8031 ​​is provided with a key bolt 8032; the lifting adjustment frame 804 is movably inserted through the lifting adjustment adapter slot 8013, and the top of the lifting adjustment frame 804 is provided with an arc-shaped meshing thread block 8041, and the meshing thread block 8041 is threadedly connected to the adjustment turntable 802; the output gear shaft 805 is rotatably arranged on the lifting adjustment frame 804, and the output gear shaft 805 is composed of a connecting shaft part 8051, a reciprocating toothed part 8052, and a secondary bevel gear part 8053; wherein, the surface of the connecting shaft part 8051 is provided with a keyway 8054 that is limited and matched with the key bolt 8032 at the position opposite to the key bolt 8032; wherein, the reciprocating toothed part 8052 is a toothed gear structure. This invention enables the lifting and adjusting frame 804 to only move up and down when it is limited by the lifting and adjusting adapter groove 8013 by manually rotating the adjusting turntable 802. During the descent operation, the reciprocating toothed part 8052 can intermittently engage with the outer adjusting tube 9 to form an oscillating adjustment. During the ascent operation, the secondary bevel gear part 8053 continuously engages with the outer adjusting tube 9 to form a unidirectional rotation adjustment. Through the above two operations, foam cleaning agent spraying operation is performed in a continuous reciprocating oscillating mode, and dry ice cleaning spraying operation is performed in a unidirectional rotation intermittent pressurized mode.

[0064] It is worth noting that the external regulating pipe 9 is composed of an outer pipe body 9011, an input bevel gear 9012, and a multi-stage bevel gear 9013. The input bevel gear 9012 and the multi-stage bevel gear 9013 are meshed with the reciprocating toothed part 8052 to form a counter-transmission structure. The multi-stage bevel gear 9013 has a meshing cavity on the side closer to the input bevel gear 9012. The meshing cavity is meshed with the second-stage bevel gear part 8053 to form a unidirectional transmission structure. The meshing cavity is larger on the outside and smaller on the inside. The outer pipe body 9011 is composed of a connecting part and an expansion part. The connecting part is arranged at the bottom of the drive base 801 via a rotating seat. The expansion part has several external spray holes 9014 arranged in an annular pattern at equal intervals on its surface. The expansion part has a screw head 9015 on the end away from the input bevel gear 9012. The screw head 9015 has at least one groove 9016 on its surface. This invention utilizes an opposing input bevel gear 9012, a multi-stage bevel gear 9013, and a dual-mode angle adjustment structure 8 to adjust the reciprocating toothed section 8052 for meshing operation. This allows the outer tube body 9011 to perform intermittent opposing rotational motion during the unidirectional rotational motion of the reciprocating toothed section 8052, creating a swinging effect. Through this swinging motion... Figure 13 The embedded disinfection and cleaning tank 2 is shown to be fully sprayed with foam cleaning agent. Based on the dual-mode angle adjustment structure 8, the reciprocating toothed part 8052 is separated, causing the secondary bevel gear part 8053 to mesh with the meshing cavity. By rotating the secondary bevel gear part 8053, the meshing cavity continuously drives the outer adjustment tube 9 to rotate in one direction. This method enables intermittent dry ice spraying, thereby achieving efficient pressurization. At the same time, the meshing cavity, which is larger on the outside and smaller on the inside, reduces the space for the secondary bevel gear part 8053 to move up and down for meshing and separation. This dual-mode disinfection and cleaning system 6 has a smaller overall size and lower manufacturing cost.

[0065] It is worth noting that the central delivery pipe 10 is arranged at the bottom of the drive base 801 via a fixed seat, and the central delivery pipe 10 is movably inserted inside the outer regulating pipe 9. A segmented groove A1001 is formed on the outer surface of the central delivery pipe 10, and the arc angle of the segmented groove A1001 is greater than the arc angle of the outer spray hole 9014. A partition sealing block A1002 is provided inside the segmented groove A1001. At least one rotating protrusion 1003 and one limiting protrusion 1004 are provided on the inner wall of the central delivery pipe 10 from the inside out. Based on the arrangement of the central delivery pipe 10 and its fixed, non-rotating operation, this invention allows any one of the outer spray holes 9014 on the surface of the outer pipe body 9011 to connect when it coincides with the segmented groove A1001, and to close when it is misaligned. Simultaneously, the arc angle of the segmented groove A1001 is greater than the arc angle of the outer spray hole 9014 to adapt to… Figure 13 The required spray range is shown.

[0066] It is worth emphasizing that the internal pressure regulating assembly 11 includes an inner tube body 1101 and a force-bearing block 1105; the inner tube body 1101 is movably arranged inside the central feed pipe 10; and the inner tube body 1101 is elastically connected to the central feed pipe 10 via a spring 1109; and a spiral extrusion groove 1102 is provided on the outer surface of the inner tube body 1101 relative to the rotational protrusion 1003; and a segment groove B1103 is provided on the outer side of the inner tube body 1101; and the arc angle of the segment groove B1103 is the same as that of the segment groove A1001. The arc angles are the same, and the partition sealing block B1104 is provided at an alternating position with the partition sealing block A1002 inside the segment groove B1103; the force block 1105 is rotatably arranged at the end of the inner tube body 1101, and the force block 1105 is provided with a linear structured limiting groove 11051 with the limiting protrusion 1004 at the position of the limiting protrusion 1004. The end of the force block 1105 is provided with a peak force protrusion 11052, and the peak force protrusion 11052 has two slopes with the same length and different widths. This invention utilizes the staggered arrangement of partition blocking blocks B1104 within the segment groove B1103 relative to the partition blocking blocks A1002. This arrangement allows for relative sealing and pressure maintenance when the segment groove B1103 overlaps with the segment groove A1001. Simultaneously, the spring 1109 causes the inner tube body 1101 to expand and rotate along the rotating protrusion 1003 via the spiral extrusion groove 1102, resulting in the partition blocking blocks A1002 and B1104 overlapping. This connects the segment groove B1103 and the segment groove A1001, with the connecting channel opening from small to large. This effectively increases the initial pressure of the downwardly sprayed dry ice, facilitating the maintenance of a good and stable impact bursting force.

[0067] In addition, the following compound force structure 12 includes a force-bearing shaft tube 1201 and a connecting threaded sleeve 1205; the force-bearing shaft tube 1201 is movably arranged inside the central delivery tube 10, and the force-bearing shaft tube 1201 is composed of an adjusting shaft body 1202 and a number of extrusion blocks 1203; wherein, the end of the adjusting shaft body 1202 is provided with a snap groove 9016 to engage with a matching snap block 1204; wherein, the ends of the extrusion blocks 1203 are triangular, and the number of extrusion blocks 1203 is the same as the number of external spray holes 9014; the connecting threaded sleeve 1205 is rotatably arranged on the adjusting shaft body 1202, and the connecting threaded sleeve 1205 is threadedly connected to the screw head 9015. This invention uses manual rotation of the threaded sleeve 1205 to cause the locking block 1204 on the force-bearing shaft tube 1201 to slide linearly along the locking groove 9016. Rotating the threaded sleeve 1205 allows the pressing block 1203 to contact or move away from the peak force-bearing protrusion 11052. Simultaneously... Figure 12As shown, during the process of the peak-loaded protrusion 11052 connecting the segment groove B1103 and the segment groove A1001 and opening the connecting channel from small to large, the compression block 1203 slides from the peak point of the slope with a relatively large slope width to the valley point of the slope with a relatively large slope width. The sliding distance and time are adapted to the unfolding distance and time of the inner tube body 1101 by the spring 1109. During the sliding process of the peak-loaded protrusion 11052 from the valley point of the slope with a relatively small slope width to the peak point of the slope with a relatively large slope width, the smaller width effectively increases the sliding time of the compression block 1105, accelerates the linear sliding of the compression block 1105 to push the inner tube body 1101 to perform spiral compression movement, and improves the compression ratio. Furthermore, the linear limiting groove 11051 and the limiting protrusion 1004 limit the sliding, preventing the compression block 1105 from following the rotation and causing driving errors and motion interference.

[0068] Example 2: A method for using a dry ice spray cleaning and sterilizing device, comprising the following steps:

[0069] S100, Pre-treatment: Dry ice, clean water, disinfectant, and foam cleaner are manually poured into the dry ice crusher 504, clean water tank 505, foam cleaner tank 506, and disinfectant tank, respectively.

[0070] S200, Placement: The surgical and medical instruments are manually placed into the embedded disinfection and cleaning tank 2 and the transparent splash guard 3 is closed.

[0071] S300, First-level adjustment process: Manually put on rubber protective gloves and manually rotate the adjustment turntable 802 to lower the lifting adjustment frame 804, so that the second-level bevel gear part 8053 disengages from the reciprocating toothed part 8052, and the reciprocating toothed part 8052 engages with the input bevel gear 9012 and the multi-stage bevel gear 9013. Then, manually rotate the connecting threaded sleeve 1205 to separate the extrusion block 1203 from the force-bearing block 1105.

[0072] S400, Pre-cleaning treatment: The foam cleaner in the foam cleaner tank 506 is drawn out by the pump, and high-pressure air is delivered synchronously by the air booster fan 501, so that the foam cleaner and high-pressure air are mixed and delivered synchronously to the central delivery pipe 10. Then, the reciprocating drive motor 702 drives the drive rod 701 to rotate, so that the drive base 801 slides along the surface of the linear limit shaft 703. At the same time, the swing drive motor 803 rotates and drives the reciprocating toothed part 8052 to drive the input bevel gear 9012 and the multi-stage bevel gear 9013 to perform counter-transmission to form a reciprocating swing operation. At this time, one of the external spray holes 9014 coincides with the section groove A1001, so that the foam cleaner mixed with high-pressure air is evenly sprayed onto the surface of the surgical and medical instruments in the embedded disinfection and cleaning tank 2, and then returns to the initial position.

[0073] S500, Secondary Adjustment Processing: Manually rotate the adjustment turntable 802 by putting on rubber protective gloves to raise the lifting adjustment frame 804. The secondary bevel gear 8053 engages with the meshing cavity. Then, manually rotate the connecting threaded sleeve 1205 to press and adhere the extrusion block 1203 to the force-bearing block 1105.

[0074] S600, Dry Ice Cleaning Process: The dry ice fed from above is pulverized by the dry ice pulverizer 504, and high-pressure air is simultaneously delivered by the air booster fan 501, causing the dry ice and high-pressure air to mix and be synchronously delivered into the central delivery pipe 10. Then, the reciprocating drive motor 702 drives the drive rod 701 to rotate, causing the drive base 801 to slide along the surface of the linear limit shaft 703. At the same time, the swing drive motor 803 drives the secondary bevel gear 8053 to drive the outer adjustment pipe 9 to rotate unidirectionally. At this time, several external spray holes 9014 sequentially coincide with the segment groove A1001. Simultaneously, the rotation of the outer pipe body 9011 synchronously drives the force-bearing shaft pipe 1201 to rotate, causing the extrusion block 1203 to slide and extrude the peak force-bearing protrusion 11052, causing the inner pipe body 1101 to move and compress the inner pipe body. The cavity space formed by 1101 and the inner wall of the central delivery tube 10, and based on the limiting cooperation of the extrusion groove 1102 and the rotating protrusion 1003, causes the inner tube body 1101 to rotate synchronously during the compression process, causing the partition sealing block A1002 and the partition sealing block B1104 to form a sealing effect. After continuous unidirectional rotation, the extrusion block 1203 slides to the peak point of the peak force protrusion 11052, and the extrusion force gradually decreases. Under the action of the spring 1109, the inner tube body 1101 resets, causing the partition sealing block A1002 and the partition sealing block B1104 to overlap, so that the segment groove B1103 and the segment groove A1001 are connected, and the connecting channel opens from small to large, effectively improving the initial stage pressure of the downward inclined dry ice spray, making it easier to maintain a good and stable impact bursting force to clean the surface of surgical and medical instruments. After the dry ice cleaning is completed;

[0075] S700, Flushing treatment: Clean water is pumped in by a pump, and high-pressure air is simultaneously delivered by an air booster fan 501 to rinse surgical and medical instruments.

[0076] S800, Drying treatment: The surgical and medical instruments are preheated and dried by electric heating through the embedded disinfection and cleaning tank 2.

[0077] S900 Disinfection treatment: The pump pumps the disinfection solution hydrogen peroxide into the embedded disinfection and cleaning tank 2 for disinfection.

[0078] S1000, Suction Treatment: The negative pressure effect created by the suction of the blower 503 draws the vaporized hydrogen peroxide component in the embedded disinfection and cleaning tank 2 from the long strip connecting channel 201 to the blower 503 and then to the outside.

[0079] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.

S400, Pre-cleaning treatment: The foam cleaner in the foam cleaner bucket (506) is sucked out by the pump, and high-pressure air is delivered synchronously by the air booster fan (501) so that the foam cleaner and high-pressure air are mixed and delivered synchronously to the central delivery pipe (10). Then, the drive rod (701) is driven to rotate by the reciprocating drive motor (702) so that the drive base (801) slides along the surface of the linear limit shaft (703). At the same time, the swing drive motor (803) rotates to drive the reciprocating toothed part (8052) to drive the input bevel gear (9012) and the multi-stage bevel gear (9013) to perform counter-transmission to form a reciprocating swing operation. At this time, one of the external spray holes (9014) coincides with the section groove A (1001), so that the foam cleaner mixed with high-pressure air is evenly sprayed onto the surface of the surgical and medical instruments in the embedded disinfection and cleaning tank (2), and then reset to the initial position. S500, Secondary Adjustment Processing: The lifting adjustment frame (804) is raised by manually rotating the adjustment turntable (802) through rubber protective gloves. The secondary bevel gear (8053) engages with the meshing cavity. Then, the extrusion block (1203) is pressed and adhered to the force block (1105) by manually rotating the connecting threaded sleeve (1205). S600, Dry Ice Cleaning Process: The dry ice fed from above is pulverized by the dry ice pulverizer (504), and high-pressure air is synchronously delivered by the air booster fan (501) to mix the dry ice with the high-pressure air and deliver it synchronously to the central delivery pipe (10). Then, the drive rod (701) is driven to rotate by the reciprocating drive motor (702) to make the drive base (801) slide along the surface of the linear limit shaft (703). At the same time, the swing drive motor (803) drives the secondary bevel gear (8053) to drive the outer adjustment pipe (9) to rotate unidirectionally. At this time, several external spray holes (9014) are sequentially aligned with the segment groove A (1001). Simultaneously, the rotation of the outer tube body (9011) synchronously drives the force-bearing shaft tube (1201) to rotate, causing the extrusion block (1203) to slide and extrude the peak force-bearing protrusion (11052), so that the inner tube body (1101) moves and compresses the inner tube. The cavity space formed by the main body (1101) and the inner wall of the central delivery pipe (10), and based on the limiting cooperation of the extrusion groove (1102) and the rotating protrusion (1003), causes the inner tube main body (1101) to rotate synchronously during the compression process, causing the partition sealing block A (1002) and the partition sealing block B (1104) to form a sealing effect. After continuous unidirectional rotation, it slides through the extrusion block (1203) to the peak point of the peak force protrusion (11052), and is squeezed. As the force gradually decreases, the inner tube body (1101) is reset under the action of the spring (1109), causing the partition sealing block A (1002) and the partition sealing block B (1104) to overlap, so that the section groove B (1103) and the section groove A (1001) are connected, and the connecting channel opens from small to large, effectively increasing the initial stage pressure of the downward sprayed dry ice, which is convenient to maintain a good and stable impact bursting force to clean the surface of surgical and medical instruments. After the dry ice cleaning is completed; S700, Flushing treatment: Clean water is pumped in by a pump, and high-pressure air is simultaneously delivered by an air booster fan (501) to rinse surgical and medical instruments; S800, Drying treatment: The surgical and medical devices are preheated and dried by electric heating through the embedded disinfection and cleaning tank (2); S900, Disinfection treatment: The pump pumps the disinfectant hydrogen peroxide into the embedded disinfection and cleaning tank (2) for disinfection; S1000, Suction Treatment: The negative pressure effect is formed by the suction of the blower (503) to transport the vaporized hydrogen peroxide component in the embedded disinfection and cleaning tank (2) from the long strip connecting tank (201) to the blower (503) to the outside.
