[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0019] This invention provides an indoor spray-type disinfection device, such as... Figure 1-16As shown, the indoor spray disinfection device includes: a bottom shell 1 and a top shell 2. The top shell 2 is slidably and vertically mounted inside the bottom shell 1, and both are extendable to change the overall height as needed. The top shell 2 has a replenishment port 3 and is equipped with a top cover. A water pump 4 is installed inside the bottom of the bottom shell 1. A water inlet hose 5 is installed on the drain end of the water pump 4. The drain end of the water inlet hose 5 passes through the top of the top shell 2. The drain end of the water inlet hose 5 is a rigid pipe and is fixedly connected to the top shell 2. A spray rigid pipe 6 is installed on the top of the top shell 2. The spray rigid pipe 6 is connected to the water inlet hose 5. An extension pipe 7 is slidably installed inside the spray rigid pipe 6. The drain end of the extension pipe 7 extends to the outside of the spray rigid pipe 6 and is fixedly mounted with a nozzle 8 for extension and retraction as needed. A positioning bolt 9 is threaded on the spray rigid pipe 6 to abut against the positioning extension pipe 7. The top of the top shell 2 is fixedly mounted with... The system is equipped with a shaft tube 10, which is located outside the rigid pipe of the water supply hose 5. A cylindrical water guide shell 11 is rotatably installed inside the shaft tube 10. The cylindrical water guide shell 11 is rotatably sleeved outside the rigid pipe of the water supply hose 5. The top of the cylindrical water guide shell 11 is fixedly connected to the water inlet end of the spray rigid pipe 6, and the two are in communication. When the cylindrical water guide shell 11 rotates along the shaft tube 10 and the rigid pipe of the water supply hose 5, water is introduced into the spray rigid pipe 6 and then sprayed out through the extension pipe 7 and the nozzle 8. A middle bevel gear 12 is fixedly sleeved on the cylindrical water guide shell 11. A motor 13 is fixedly installed on the top of the top shell 2. A drive bevel gear 14 is fixedly installed on the output shaft of the motor 13. The drive bevel gear 14 meshes with the middle bevel gear 12 to drive the cylindrical water guide shell 11 and the spray rigid pipe 6 to rotate. Multiple universal wheels 36 are fixedly installed on the bottom of the bottom shell 1 for movement.
[0020] In this embodiment, when using this device, the telescopic cooperation state of the bottom shell 1 and the top shell 2 can be adjusted according to the height environment of the indoor disinfection space to change the overall height of the device and adapt to indoor scenarios with different floor heights. Staff can add disinfectant into the device through the replenishment port 3 on the top of the top shell 2 and seal the replenishment port 3 with the top cover. For different disinfection coverage requirements, the positioning bolt 9 on the water spray pipe 6 can be loosened, and the extension pipe 7 can be pulled to slide and extend inside the water spray pipe 6 to adjust the extension length of the nozzle 8. After adjustment, the positioning bolt 9 can be locked to fix the extension pipe 7 in place. The device can move freely in all directions with the help of multiple casters 36 at the bottom of the bottom shell 1 to achieve mobile disinfection throughout the indoor area. At the same time, the motor 13 installed on the top of the top shell 2 can be started to provide power for the rotation spray of the disinfection spray, adapting to the needs of fixed-point large-area disinfection operations. This device relies on the sliding, lifting, and telescopic structure of the bottom shell 1 and the top shell 2 to achieve adaptive adjustment of the overall height of the device, adapting to various restricted indoor spaces. The water pump 4 installed at the bottom of the bottom shell 1 serves as the power source for liquid transportation. When the water pump 4 is working, it continuously introduces disinfectant into the water supply hose 5. The water supply hose 5 adapts to the telescopic movement of the top shell 2, while its top rigid pipe section remains fixed to the top shell 2, ensuring the stability of the liquid transportation path. The disinfectant is introduced into the column water guide shell 11 through the water supply hose 5, and then flows into the spray hard pipe 6 connected to it. Finally, it is delivered to the nozzle 8 through the extension pipe 7 to complete the atomization spray. When the motor 13 is working, it drives the active bevel gear 14 on the output shaft to rotate. Through gear meshing, it drives the middle bevel gear 12 to rotate synchronously, thereby driving the column water guide shell 11 to rotate inside the shaft tube 10 and outside the rigid pipe of the water supply hose 5. This causes the spray hard pipe 6, the extension pipe 7, and the nozzle 8 to rotate circumferentially as a whole, realizing the rotary spray disinfection of the disinfectant, covering the indoor air and object surfaces in all directions. This device, through the telescopic structure design of the bottom shell 1 and top shell 2, can flexibly change the overall height of the device, effectively adapting to indoor disinfection scenarios of different heights. This solves the problem of traditional disinfection equipment having a fixed size and being unable to fit into low-ceilinged spaces, greatly improving the device's applicability to various scenarios. Through the telescopic cooperation structure of the water spray pipe 6 and the extension pipe 7, the spray extension distance of the nozzle 8 can be flexibly adjusted. Combined with the positioning and locking function of the positioning bolt 9, it can accurately adapt to the disinfection needs of different areas and distances, improving the flexibility and accuracy of disinfection operations. With the meshing transmission structure of the motor 13, the active bevel gear 14, and the middle bevel gear 12, the nozzle 8 can be driven to rotate and spray in a circumferential direction, breaking away from the limitations of traditional fixed-angle spraying, expanding the disinfection coverage area, and achieving disinfection without dead angles indoors. The universal wheels 36 set at the bottom of the bottom shell 1 allow the device to move and transport freely, accommodating both fixed-point rotational disinfection and all-area mobile disinfection operation modes, realizing flexible switching between mobile and fixed use conditions, and effectively meeting the needs of normalized and comprehensive indoor disinfection operations.
[0021] In a further preferred embodiment of the present invention, a circular track 15 is fixedly installed on the top of the top shell 2, and a sliding block 16 is rotatably installed on the circular track 15. The sliding block 16 is fixedly connected to the water spray hard pipe 6 and is used to guide the water spray hard pipe 6 to rotate stably.
[0022] In this embodiment, when the equipment is started to perform rotary spray disinfection, a circular track 15 is fixedly installed on the top of the top shell 2 to provide a dedicated guide reference for the rotational movement of the water spray pipe 6. When the water spray pipe 6 rotates circumferentially with the column water guide shell 11, the sliding block 16 fixed on the water spray pipe 6 can engage with the circular track 15 and slide synchronously. Relying on the ring structure constraint of the circular track 15, the movement trajectory of the sliding block 16 can be limited, thereby restricting the rotation path of the water spray pipe 6 and preventing the water spray pipe 6 from deviating, shaking or eccentrically swinging during high-speed rotation. This ensures that the water spray pipe 6 always maintains a regular circumferential rotation state, and helps to ensure the stability and coaxiality of the rotary spray structure transmission operation.
[0023] In a further preferred embodiment of the present invention, a bearing seat 17 is fixedly installed on the bottom inner wall of the bottom shell 1, and a splined cylinder 18 is rotatably installed on the bearing seat 17. Multiple stirring rods 19 are fixedly installed on the splined cylinder 18 for stirring disinfectant. A splined shaft 20 is rotatably installed on the top inner wall of the top shell 2. The bottom end of the splined shaft 20 extends into the splined cylinder 18 so that the two rotate synchronously and can follow the lifting and lowering extension of the top shell 2. The top end of the splined shaft 20 extends out of the top shell 2 and is fixedly installed with a driven bevel gear 21. The driven bevel gear 21 meshes with the middle bevel gear 12 so that spray disinfection and stirring are synchronized.
[0024] In this preferred embodiment, during the spray disinfection operation, the rotating conical gear 12 simultaneously drives the driven conical gear 21, causing the spline shaft 20 to rotate synchronously. The rotation of the spline shaft 20 drives the spline cylinder 18 at its bottom to rotate, causing the multiple stirring rods 19 fixed to the outside of the spline cylinder 18 to rotate synchronously, continuously stirring the disinfectant stored inside the bottom shell 1. When the top shell 2 adjusts the overall height of the equipment relative to the bottom shell 1, the spline shaft 20 can extend and retract relative to the spline cylinder 18, maintaining a constant transmission relationship with the spline cylinder 18, ensuring that both the stirring and spraying functions operate synchronously and normally under height adjustment conditions. The meshing transmission structure of the middle bevel gear 12 and the driven bevel gear 21 enables the spray rotation structure and the stirring structure to be linked by the same power source, eliminating the need for a separate drive power component, simplifying the overall structure of the equipment, and reducing the production and use costs. The telescopic fit structure of the spline shaft 20 and the spline cylinder 18 can be adapted to the telescopic adjustment of the top shell 2 and the bottom shell 1, ensuring that the stirring function can work normally under any height adjustment state, ensuring structural adaptability and functional integrity. The stirring rod 19 rotates continuously with the spline cylinder 18, which can uniformly stir the disinfectant water inside the bottom shell 1, effectively avoiding sedimentation and uneven concentration during the standing of the disinfectant water, ensuring that the concentration of the sprayed disinfectant is always uniform and stable during the disinfection process, and greatly improving the overall disinfection effect of indoor disinfection operations.
[0025] In a further preferred embodiment of the present invention, an isolation plate 22 is fixedly installed inside the bottom shell 1. The isolation plate 22 is located between the stirring rod 19 and the water supply hose 5, and is used to isolate the extension and retraction of the water supply hose 5 when the top shell 2 is extended or retracted.
[0026] In this embodiment, by fixing an isolation plate 22 inside the bottom shell 1, the isolation plate 22 is used to divide the bottom shell 1 into an independent pipeline movement area and a stirring operation area. The isolation plate 22 is stably set in the middle position between the stirring rod 19 and the water supply hose 5. It can limit and block the position of the rotating stirring rod 19, and at the same time shield and protect the water supply hose 5 which moves with the extension and retraction of the top shell 2. This completely isolates the movement space of the stirring structure and the water supply structure, prevents the two from interfering with each other or touching each other during the operation of the equipment, and ensures that each structure works independently according to the predetermined trajectory.
[0027] In a further preferred embodiment of the present invention, a rubber telescopic tube 23 is fixedly installed between the bottom inner wall of the bottom shell 1 and the bottom of the top shell 2 for sealing connection between the two. The rubber telescopic tube 23 has the same inner diameter as the top shell 2, and the inner diameter of the bottom shell 1 has the same outer diameter as the top shell 2.
[0028] In this embodiment, during equipment use, when the top shell 2 is raised or lowered relative to the bottom shell 1, the rubber telescopic tube 23 installed between the bottom inner wall of the bottom shell 1 and the bottom of the top shell 2 expands and contracts synchronously with the raising and lowering motion of the top shell 2. The rubber telescopic tube 23 always maintains a sealed connection between the bottom shell 1 and the top shell 2, continuously sealing the gap between the bottom shell 1 and the top shell 2 throughout the entire height adjustment process. This ensures that the equipment maintains an internal sealed environment at any height, guaranteeing the normal operation of equipment expansion and contraction adjustments and routine disinfection work.
[0029] In a further preferred embodiment of the present invention, a guide groove 24 is provided on the inner wall of the bottom shell 1, and a guide block 25 is slidably installed in the guide groove 24. The guide block 25 is fixedly connected to the side of the top shell 2 and is used to guide the lifting and stretching of the top shell 2.
[0030] In this embodiment, when adjusting the overall height of the equipment, the top shell 2 moves up and down relative to the bottom shell 1. During the up and down movement of the top shell 2, the guide block 25 fixedly connected to the side moves synchronously, causing the guide block 25 to slide vertically along the guide groove 24 opened on the inner wall of the bottom shell 1. The guide groove 24 and the guide block 25 work together throughout the process to limit and guide the up and down movement of the top shell 2, ensuring that the extension and retraction adjustment process of the top shell 2 is smooth and stable, and assisting in the adaptive adjustment of the overall height of the equipment.
[0031] In a further preferred embodiment of the present invention, at least two bearing seats 26 are fixedly installed on the inner wall of the top of the top shell 2. A lifting threaded cylinder 27 is rotatably installed on each of the at least two bearing seats 26. A lifting screw 28 is threadedly installed inside each of the at least two lifting threaded cylinders 27. The bottom ends of the at least two lifting screws 28 are fixedly connected to the inner wall of the bottom of the bottom shell 1, so that the lifting threaded cylinder 27 moves up and down along the lifting screw 28 when it rotates, thereby driving the top shell 2 to extend and retract within the bottom shell 1. A driven spur gear 29 is fixedly sleeved on each of the at least two lifting threaded cylinders 27. A circular track 3 is fixedly installed on the inner wall of the top shell 2. 0. A transmission ring 31 is rotatably sleeved on the circular track 30. A circular toothed assembly 32 is fixedly installed on the inner side of the transmission ring 31. The circular toothed assembly 32 meshes with at least two driven spur gears 29 to drive at least two lifting threaded cylinders 27 to rotate. An external toothed ring 33 is fixedly installed on the top of the transmission ring 31. A turning shaft 34 is rotatably installed on the inner wall of the top of the top shell 2. A driving spur gear 35 is fixedly installed at the bottom end of the turning shaft 34. The driving spur gear 35 meshes with the external toothed ring 33 to drive the external toothed ring 33 and the transmission ring 31 to rotate synchronously.
[0032] In this embodiment, when adjusting the overall height of the equipment, the operator can rotate the screw shaft 34 mounted on the inner wall of the top shell 2. During the rotation of the screw shaft 34, the drive gear 35 fixed at the bottom will rotate synchronously. The drive gear 35 meshes and drives the outer gear ring 33 to rotate, causing the transmission ring 31 to rotate along the circular track 30. The circular tooth group 32 on the inner side of the transmission ring 31 synchronously drives multiple driven gears 29 to rotate, causing each lifting screw cylinder 27 to rotate synchronously. During the rotation of the lifting screw cylinder 27, it moves vertically along the lifting screw 28, thereby driving the top shell 2 to complete the automatic extension and retraction adjustment relative to the bottom shell 1, realizing the stable and precise control of the equipment height, and meeting the height adaptation requirements of different disinfection scenarios. Multiple bearing seats 26 fixed to the inner wall of the top of the top shell 2 provide rotational support for the lifting threaded cylinder 27, enabling the lifting threaded cylinder 27 to rotate stably. The lifting threaded cylinder 27 and the lifting screw 28 form a threaded transmission engagement. The bottom end of the lifting screw 28 is fixed to the inner wall of the bottom of the bottom shell 1, maintaining a fixed and stationary state. When the lifting threaded cylinder 27 rotates, it can achieve vertical lifting displacement by relying on the threaded engagement. The driven round gears 29 fixed on the outer side of each lifting threaded cylinder 27 mesh with the circular tooth set 32 on the inner side of the transmission ring 31. The circular track 30 plays a role in limiting rotation and guiding support for the transmission ring 31, ensuring that the transmission ring 31 rotates smoothly in the circumference. The driving round gear 35 at the bottom of the turning shaft 34 forms a meshing transmission structure with the outer tooth ring 33 at the top of the transmission ring 31. By rotating the turning shaft 34, torque can be transmitted, driving the transmission ring 31 to rotate as a whole, synchronously driving all driven round gears 29 and lifting threaded cylinders 27 to rotate synchronously, thereby driving the top shell 2 to complete the overall telescopic lifting action.
[0033] In a further preferred embodiment of the present invention, the top end of the screwing shaft 34 extends to the outside of the top shell 2 and is fixedly mounted with a screwing block, the screwing block being located outside the circular track 15.
[0034] In this embodiment, when adjusting the height of the equipment, the operator can directly operate the screw block exposed outside the top shell 2. By rotating the screw block, the entire screw shaft 34 is rotated, thereby completing the telescopic adjustment of the equipment height. The screw block is arranged on the outside of the circular track 15, and the operator can completely avoid the circular track 15 when operating the screw block.
[0035] In a further preferred embodiment of the present invention, there is a gap between the bottom of the isolation plate 22 and the bottom inner wall of the bottom shell 1 for solution flow, and the top of the isolation plate 22 is arc-shaped and tilts to one side of the upward water hose 5 from the spline tube 18.
[0036] In this embodiment, by leaving a gap between the bottom of the isolation plate 22 and the inner wall of the bottom of the bottom shell 1, the flow channels of disinfectant on both sides of the isolation plate 22 are opened, the spatial obstruction of disinfectant by the isolation plate 22 is broken, and the disinfectant in the separated area can communicate with each other; the top of the isolation plate 22 is set as an arc-shaped structure inclined towards the water supply hose 5, which can guide the extension and retraction of the water supply hose 5.
[0037] In a further preferred embodiment of the present invention, the motor 13 is located inside the circular track 15, and the height of the motor 13 is lower than the height of the circular track 15.
[0038] In this embodiment, by limiting the installation position and height of the motor 13, the motor 13 is housed and arranged inside the inner area of the circular track 15, and the power components are arranged in the unused space inside the circular track 15. Based on the structural layout that the overall height of the motor 13 is lower than the height of the circular track 15, the motor 13 is completely housed below the vertical space of the circular track 15, completely avoiding the circular sliding motion path of the circular track 15 and the sliding block 16. This allows the fixed installation structure of the motor 13 and the track guiding motion structure to form a spatially layered layout, ensuring that each structure can independently complete the predetermined working stroke.
[0039] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a base plate 37 is vertically mounted on the bottom of the bottom shell 1. The base plate 37 has multiple clearance openings 38 for avoiding the casters 36 when it is raised or lowered. An outer shell 39 is fixedly mounted on the outside of the top shell 2. The outer shell 39 is slidably sleeved on the outside of the bottom shell 1. A single rubber telescopic tube 40 is fixedly installed between the bottom of the outer shell 39 and the top of the base plate 37. A support sleeve 41 is slidably sleeved on the bottom of the bottom shell 1. The bottom of the support sleeve 41 is fixedly connected to the top of the base plate 37 so that they rise and fall synchronously. The top shell 2, the base plate 37, and the support sleeve 41 rise and fall synchronously. At least two transmission blocks 42 are fixedly installed on the outer side of the support sleeve 41, and at least two assembly plates 43 are fixedly installed on the outer side of the bottom shell 1. Both assembly plates 43 are located inside the outer shell 39 and are respectively located vertically above the at least two transmission blocks 42. A lifting shaft 44 is rotatably mounted on each of the at least two assembly plates 43. Both lifting shafts 44 slide through the bottom inner wall of the outer shell 39 to prevent interference between them. The bottom ends of both lifting shafts 44 are threaded sections 45, which thread through the corresponding transmission blocks 42 to drive the support sleeve 41 and... The base plate 37 is raised and lowered. At least two connecting blocks 46 are fixedly installed on the outer side of the top shell 2. Mouth-shaped frames 47 are fixedly installed on each of the at least two connecting blocks 46. Lifting tooth assemblies 48 are fixedly installed on the outer side of each of the at least two mouth-shaped frames 47. At least two sets of fixing seats 1 49 and fixing seats 2 53 are fixedly installed on the outer side of the base shell 1. The fixing seats 2 53 are located between the corresponding assembly plates 43 and fixing seats 1 49, and are all located inside the outer shell 39. A limiting plate 50 that slides through the mouth-shaped frame 47 is fixedly installed on the fixing seat 1 49 for guiding the mouth-shaped frame 47 to rise and fall. A rotatable mounting plate is installed on the fixing seat 1 49. A drive shaft 51 is provided, on which a spur gear 52 is fixedly sleeved. The spur gear 52 meshes with a lifting gear assembly 48, so that the drive shaft 51 is driven to rotate when the top shell 2 is raised or lowered. A drive shaft 54 is rotatably mounted on a fixed base 53, on which a spur gear 55 is fixedly sleeved. The spur gear 55 meshes with the spur gear 52, so that the drive shaft 51 drives the drive shaft 54 to rotate. Synchronous bevel gears 56 are fixedly mounted on both the drive shaft 54 and the lifting shaft 44. The two synchronous bevel gears 56 mesh with each other, so that the drive shaft 54 drives the lifting shaft 44 to rotate.
[0040] In this embodiment, during equipment use, when the operator adjusts the top shell 2 by raising or lowering it, the top shell 2 will drive the outer fixed connecting block 46 and the mouth-shaped frame 47 to move up and down synchronously. The mouth-shaped frame 47 slides vertically along the limiting plate 50 mounted on the fixed seat 49 to complete the lifting and lowering guide. The lifting tooth assembly 48 on the outer side of the mouth-shaped frame 47 moves synchronously and drives the meshing spur gear 52 to rotate, which in turn drives the transmission shaft 51 to rotate. The transmission shaft 51 drives the transmission shaft 54 to rotate through the meshing relationship between the spur gear 52 and the spur gear 55. The transmission shaft 54 rotates synchronously through the meshing relationship between the spur gear 52 and the spur gear 55. The bevel gear 56 drives the lifting shaft 44 to rotate; the threaded section 45 at the bottom of the lifting shaft 44, in conjunction with the transmission block 42, drives the support sleeve 41 and the base plate 37 to complete the lifting action synchronously, so that the base plate 37 can follow the top shell 2 to achieve synchronous lifting and adjustment. After the base plate 37 is fully extended, it can be placed directly, so that the casters 36 can be stored and placed more stably; during the lifting and lowering process, the base plate 37 avoids structural interference of the casters 36 through the avoidance opening 38 it has opened. At the same time, the outer shell 39 moves synchronously with the top shell 2, and in conjunction with the rubber telescopic tube 40, it completes the full-range adaptive extension and retraction, ensuring that the overall lifting and adjustment operation of the equipment is completed smoothly. The mouth-shaped frame 47 is fixedly supported by the connecting block 46 on the outside of the top shell 2. The limiting plate 50 passes through the mouth-shaped frame 47 and vertically limits and guides the lifting and lowering movement of the mouth-shaped frame 47, ensuring that the mouth-shaped frame 47 can only make regular vertical displacement. When the mouth-shaped frame 47 is raised and lowered, the linear lifting and lowering movement of the top shell 2 is converted into the rotational movement of the transmission shaft 51 through the meshing of the lifting gear set 48 and the first spur gear 52. Then, through the meshing of the first spur gear 52 and the second spur gear 55, the power is transmitted to the second transmission shaft 54. The second transmission shaft 54 and the lifting shaft 44 realize the power reversal transmission through the meshing of two sets of synchronous bevel gears 56, driving the lifting shaft 44 to rotate. The threaded section 45 at the bottom end forms a threaded transmission structure with the transmission block 42, which converts the rotational motion of the lifting shaft 44 into the vertical linear motion of the transmission block 42, thereby driving the support sleeve 41 fixed to the transmission block 42 and the base plate 37 to rise and fall synchronously; the support sleeve 41 slidably sleeved on the outside of the bottom shell 1 supports and guides the rise and fall of the base plate 37, the outer shell 39 slidably sleeved on the outside of the bottom shell 1 to achieve follow-up adaptation, the rubber telescopic tube 40 between the outer shell 39 and the base plate 37 adaptively extends and retracts with the rise and fall action, and the base plate 37, through the structure setting of the avoidance opening 38, ensures that there will be no structural interference with the universal wheel 36 during the rise and fall process, and finally realizes the linkage and synchronous rise and fall function of the top shell 2 and the base plate 37; Through a multi-stage meshing transmission structure of gears and tooth sets, the mechanical linkage between the lifting action of the top shell 2 and the lifting action of the bottom plate 37 is realized. There is no need to set up a separate drive structure to control the lifting of the bottom plate 37. The state switching of the bottom support structure can be completed simultaneously while adjusting the overall height of the equipment, which greatly simplifies the equipment adjustment operation steps and improves the linkage and synchronization of the equipment height adjustment. The guide and limit function of the limit plate 50 on the mouth-shaped frame 47 can ensure the accuracy and stability of the overall transmission structure, avoid jamming and wear caused by transmission deviation, and improve the service life and transmission efficiency of the multi-stage transmission structure. The avoidance opening 38 set on the bottom plate 37 can effectively avoid structural interference between the bottom plate 37 and the universal wheel 36 during the lifting process, ensuring smooth lifting of the bottom support structure, and at the same time, it can provide protection for the universal wheel 36. The cooperation structure of the outer shell 39 and the rubber telescopic tube 40 can provide overall closed protection for the transmission structure and lifting structure on the outside of the bottom shell 1, preventing external dust and moisture from entering the internal transmission area and reducing the corrosion and dust accumulation of parts. The support sleeve 41 can improve the stability of the lifting support of the bottom plate 37.
[0041] In another embodiment of the present invention, at least two guide grooves 57 are provided on the outer wall of the bottom shell 1, and guide blocks 58 are slidably installed in each of the at least two guide grooves 57. The at least two guide blocks 58 are fixedly connected to the inner wall of the support sleeve 41 for guiding its stable lifting and lowering.
[0042] In this embodiment, a guide groove 57 is provided on the outer wall of the bottom shell 1 to provide a fixed vertical sliding trajectory for the lifting and lowering movement of the support sleeve 41; the guide block 58 is fixed to the inner wall of the support sleeve 41 and slidably embedded in the guide groove 57, so that a sliding fit structure is formed between the support sleeve 41 and the outer wall of the bottom shell 1; during the process of the support sleeve 41 following the bottom plate 37 to perform vertical lifting and lowering displacement, the guide groove 57 can constrain the movement direction and movement range of the guide block 58, restrict the support sleeve 41 to only perform linear lifting and lowering movement in the vertical direction, constrain the horizontal offset and radial swing of the support sleeve 41, and ensure that the support sleeve 41 maintains a regular vertical lifting and lowering state throughout the entire process.
[0043] In summary, compared with related technologies, this device, through the telescopic structure design of the bottom shell 1 and the top shell 2, can flexibly change the overall height of the device, effectively adapting to indoor disinfection scenarios of different heights. This solves the problem of traditional disinfection equipment having a fixed size and being unable to fit into low spaces, greatly improving the device's applicability to various scenarios. The universal wheels 36 at the bottom of the bottom shell 1 allow the device to move and be transported freely, accommodating both fixed-point rotational disinfection and all-area mobile disinfection operation modes. This enables flexible switching between mobile and fixed usage conditions, effectively meeting the needs of routine and comprehensive indoor disinfection operations.
