Abstract
Description
Technical Field
[0001] This application relates to the technical field of spray equipment, and more particularly to a disinfection and sterilization spray device. Background Technology
[0002] The disinfection and sterilization spray device is an automated / semi-automated equipment that integrates fluid delivery, atomization generation, disinfection medium storage, and control system. It converts liquid disinfection media (such as chlorine-containing disinfectants, hydrogen peroxide, quaternary ammonium salts, etc.) into droplets through mechanical or pneumatic means, and evenly disperses them in the target space or on the surface of the object. It utilizes the chemical properties of the disinfection medium to destroy the cell membrane, nucleic acid, or enzyme system of microorganisms (bacteria, viruses, fungi, etc.), thereby achieving sterilization and inactivation.
[0003] Currently, traditional disinfection spray devices mainly consist of components such as a liquid storage tank, atomizing nozzles, a moving mechanism, and a control system. The liquid storage tank stores the liquid disinfectant medium, which is then transported through pipelines and sprayed out through the atomizing nozzles, evenly dispersing the droplets into the target space to achieve disinfection. However, in practice, these devices still have the following shortcomings: Existing disinfection spray devices often employ fixed or single-dimensional oscillating nozzle designs, resulting in limited spray coverage. This is especially problematic in large-area disinfection scenarios, where frequent manual relocation of equipment is required to fill blind spots, leading to cumbersome operation procedures and reduced overall disinfection efficiency. Summary of the Invention
[0004] This application aims to at least partially address one of the technical problems in the related art.
[0005] Therefore, one objective of this application is to provide a disinfection and sterilization spray device that, by setting a multi-dimensional angle adjustment mechanism, allows the spray component to flexibly swing in both azimuth and pitch dimensions, thereby significantly expanding the spray coverage area, reducing the frequency of manual equipment movement, and improving the efficiency of disinfection operations.
[0006] To achieve the above objectives, the first embodiment of this application proposes a disinfection and sterilization spray device, characterized in that it includes a trolley, a liquid storage tank, a delivery pump, a spray assembly, and an angle adjustment mechanism. The liquid storage tank is mounted on the trolley and connected to the spray assembly via the delivery pump. The spray assembly is movably mounted on the trolley via the angle adjustment mechanism. The angle adjustment mechanism includes a rotating shaft, a base, an azimuth adjustment assembly, and a pitch adjustment structure. The bottom end of the rotating shaft is rotatably mounted on the base, and its top end is connected to the spray assembly.

The pitch adjustment structure includes a linkage assembly and a connecting assembly. The connecting assembly is connected to both the spray assembly and the linkage assembly, and the linkage assembly is connected to the rotating shaft.
[0007] The disinfection and sterilization spray device of this application embodiment, by setting an azimuth adjustment component, drives the spray component to swing back and forth in the horizontal direction to form a fan-shaped coverage area, effectively expanding the coverage range of the spray in the horizontal direction. At the same time, by setting a linkage component, the spray component can make pitching motion around the support axis, also forming a fan-shaped coverage area. Through this multi-dimensional swinging spraying method, the coverage range of the spray is greatly increased, the coverage blind spots are reduced, and the movement frequency of the equipment is reduced, enabling the disinfection and sterilization spray device to adapt to the disinfection needs in large-area disinfection scenarios and improve the efficiency of disinfection operations.
[0008] In addition, the disinfection and sterilization spray device proposed in this application may also have the following additional technical features: In one embodiment of this application, the spray assembly includes two support shafts, a support frame, a fan, a mounting ring, and a plurality of atomizing nozzles. The mounting ring is rotatably mounted within the support frame via the two support shafts. The plurality of atomizing nozzles are mounted on the mounting ring and are equidistantly distributed along the edge of the mounting ring. The fan is mounted within the mounting ring.
[0009] In one embodiment of this application, the azimuth adjustment assembly includes a gear ring, a gear plate, a sliding seat, a drive rod, a support seat, and a drive member. The drive member is disposed on the support seat, and its output shaft is provided with a first drive disk. The drive rod is eccentrically disposed on the first drive disk and located inside the sliding seat. The sliding seat is slidably disposed within the support seat. The gear plate is disposed on the sliding seat and meshes with the gear ring. The gear ring is disposed on the rotating shaft.
[0010] In one embodiment of this application, the linkage component includes a first bevel gear, a second bevel gear, a linkage shaft, and a support plate. The first bevel gear is rotatably mounted on the shaft, the second bevel gear is perpendicular to the first bevel gear and meshes with it, the second bevel gear is mounted on the linkage shaft, the linkage shaft is rotatably mounted on the support plate, and the support plate is mounted on the shaft.
[0011] In one embodiment of this application, the connecting assembly includes a connecting shaft, a connecting seat, a connecting frame, a connecting rod, and a second drive disk. The connecting shaft is disposed within the connecting frame and movably disposed within the connecting seat. One end of the connecting rod is rotatably disposed on the connecting frame, and the other end of the connecting rod is eccentrically disposed on the second drive disk.

[0016] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0017] The disinfection and sterilization spray device according to an embodiment of this application will now be described with reference to the accompanying drawings.
[0018] like Figure 1-6 As shown in the figure, a disinfection and sterilization spray device according to an embodiment of this application may include a handcart 1, a liquid storage tank 2, a delivery pump 3, a spray assembly 5 and an angle adjustment mechanism, wherein the liquid storage tank 2 is disposed on the handcart 1 and the liquid storage tank 2 is connected to the spray assembly 5 through the delivery pump 3.
[0019] It should be noted that the storage tank 2 is used to store liquid disinfectant, and the delivery pump 3 is responsible for delivering the disinfectant in the storage tank 2 to the spray assembly 5. The delivery pump 3 is installed on the protective cover 4. The inlet of the delivery pump 3 is connected to the storage tank 2 through a pipe, and the outlet of the delivery pump 3 is connected to the atomizing nozzle 55 in the spray assembly 5 through a pipe.
[0020] A protective cover 4 is provided on the handcart 1. The protective cover 4 is fitted outside the angle adjustment mechanism. The spray component 5 is located above the protective cover 4 and is movably mounted on the handcart 1 through the angle adjustment mechanism.
[0021] Understandably, the protective cover 4 can effectively protect the angle adjustment mechanism, preventing it from being interfered with or damaged by the external environment and extending the service life of the equipment. The top of the protective cover 4 is provided with a clearance groove, which can allow the angle adjustment mechanism to pass through during the disinfection operation.
[0022] The angle adjustment mechanism includes a rotating shaft 6, a base 10, an azimuth adjustment component 7, and a pitch adjustment structure. The bottom end of the rotating shaft 6 is rotatably mounted on the base 10, and its top end is connected to the spray component 5. The azimuth adjustment component 7 is mounted on the base 10 and is used to drive the spray component 5 to reciprocate along the circumference of the rotating shaft 6. The pitch adjustment structure includes a linkage component 8 and a connecting component 9. The connecting component 9 is connected to both the spray component 5 and the linkage component 8, and the linkage component 8 is connected to the rotating shaft 6.
[0023] It should be noted that the base 10 is fixedly installed on the handcart 1, providing stable support for the angle adjustment mechanism. The azimuth adjustment component 7 can adjust the spray angle of the spray component 5 in the horizontal direction by driving the rotating shaft 6 to rotate around its own axis, thereby expanding the coverage range of the spray in the horizontal direction. The pitch angle adjustment structure can adjust the spray angle of the spray component 5 in the vertical direction through the cooperation of the linkage component 8 and the connecting component 9, further enhancing the spray coverage range. Through the multi-angle adjustment method, the disinfection and sterilization spray device can adapt to the disinfection needs of large-area disinfection scenarios and improve the efficiency of disinfection operations.
[0024] In one embodiment of this application, such as Figures 1-3 As shown, the spray assembly 5 includes two support shafts 51, a support frame 52, a fan 53, a mounting ring 54, and multiple atomizing nozzles 55. The mounting ring 54 is rotatably mounted in the support frame 52 via the two support shafts 51. The multiple atomizing nozzles 55 are mounted on the mounting ring 54 and are equidistantly distributed along the edge of the mounting ring 54. The fan 53 is mounted inside the mounting ring 54.
[0025] It should be noted that the support frame 52 is U-shaped and is rotatably mounted on the protective cover 4. The top end of the rotating shaft 6 is fixedly connected to the lower surface of the support frame 52. The support shaft 51 is rotatably mounted inside the support frame 52 through bearings, and the adjacent ends of the two support shafts 51 are fixedly mounted on the outer wall of the mounting ring 54. The mounting ring 54 has a mounting groove inside, and the atomizing nozzle 55 is installed in the mounting groove. The liquid inlet of the atomizing nozzle 55 is connected to the delivery pump 3 through a pipe.
[0026] The fan 53 is a variable frequency fan. By controlling the wind speed of the fan 53, the distance of the droplets sprayed by the atomizing nozzle 55 can be adjusted to suit different working conditions.
[0027] Specifically, when the delivery pump 3 is working, it delivers the liquid disinfectant medium in the storage tank 2 to the atomizing nozzle 55. The atomizing nozzle 55 atomizes the liquid disinfectant medium into tiny droplets. At the same time, the fan 53 starts, and the airflow it generates will carry the droplets to spread in all directions, thereby achieving disinfection.
[0028] In one embodiment of this application, such as Figures 3-5As shown, the azimuth adjustment assembly 7 includes a gear ring 71, a gear plate 72, a sliding seat 73, a drive rod 74, a support seat 76, and a drive member 77. The drive member 77 is mounted on the support seat 76, and its output shaft is provided with a first drive disk 75. The drive rod 74 is eccentrically mounted on the first drive disk 75 and located inside the sliding seat 73. The sliding seat 73 is slidably mounted inside the support seat 76. The gear plate 72 is mounted on the sliding seat 73 and meshes with the gear ring 71. The gear ring 71 is mounted on the rotating shaft 6.
[0029] It should be noted that the gear ring 71 is fixedly installed on the outer wall of the rotating shaft 6, the driving component 77 is a geared motor, which is installed on the support seat 76 and fixedly connected to the first driving disk 75, the driving rod 74 is fixedly installed on the first driving disk 75 and is eccentrically set, the sliding seat 73 is provided with a sliding groove inside, and the outer wall of the driving rod 74 is in contact with the inner wall of the sliding groove.
[0030] In addition, a guide rod is fixedly installed inside the support base 76, and the sliding base 73 is slidably installed on the outer wall of the guide rod. The guide rod can guide the sliding base 73, making the sliding base 73 more stable during movement and preventing deviation. The toothed plate 72 is fixedly installed on the outer wall of the sliding base 73 and meshes with the toothed ring 71.
[0031] Based on this, when the drive component 77 is working, it drives the first drive disc 75 to rotate. The first drive disc 75 drives the drive rod 74 to make an eccentric motion. The drive rod 74 drives the sliding seat 73 to slide within the support seat 76. The sliding of the sliding seat 73 drives the toothed plate 72 to move. The toothed plate 72 drives the toothed ring 71 to rotate. When the toothed ring 71 rotates, it drives the rotating shaft 6 to rotate around its own axis. The rotating shaft 6 drives the spray assembly 5 to rotate in the horizontal direction, thereby adjusting the azimuth angle of the spray assembly 5, realizing the adjustment of the spray angle in the horizontal direction, and expanding the coverage range of the spray in the horizontal direction.
[0032] Understandably, driven by the first drive disc 75 and the drive rod 74, the sliding seat 73 can reciprocate linearly along the guide rod, and the rotating shaft 6 further drives the spray assembly 5 to swing back and forth along the axis of the rotating shaft 6. Through the reciprocating swing, the spray can form a fan-shaped coverage area in the horizontal direction, which greatly increases the coverage range of the spray and reduces the coverage blind spots in the disinfection operation.
[0033] In one embodiment of this application, such as Figure 6 As shown, the linkage assembly 8 includes a first bevel gear 81, a second bevel gear 82, a linkage shaft 83, and a support plate 84. The first bevel gear 81 is mounted on the rotating shaft 6, the second bevel gear 82 is perpendicular to the first bevel gear 81 and meshes with it, the second bevel gear 82 is mounted on the linkage shaft 83, the linkage shaft 83 is rotatably mounted on the support plate 84, and the support plate 84 is mounted on the rotating shaft 6.
[0034] It should be noted that the first bevel gear 81 is rotatably mounted on the outer wall of the rotating shaft 6 via a bearing and is fixedly connected to the protective cover 4. When the rotating shaft 6 rotates, the first bevel gear 81 will not rotate synchronously. The second bevel gear 82 is fixedly mounted on the linkage shaft 83. The linkage shaft 83 is rotatably mounted on the support plate 84 via a bearing. The support plate 84 is fixedly mounted on the outer wall of the rotating shaft 6. The support plate 84 can provide stable support for the linkage shaft 83.
[0035] Based on this, when the rotating shaft 6 rotates under the drive of the azimuth adjustment component 7, it will drive the support plate 84 to rotate synchronously. The support plate 84 drives the second bevel gear 82 synchronously through the linkage shaft 83. The second bevel gear 82 rotates around the circumference of the rotating shaft 6. Since the position of the first bevel gear 81 is fixed and it is meshed with the second bevel gear 82, the second bevel gear 82 rotates around its own axis as it follows the rotation of the support plate 84. In turn, the second bevel gear 82 synchronously drives the linkage shaft 83 to rotate within the support plate 84. Through the rotation of the linkage shaft 83, a power basis can be provided for the synchronous rotation of the subsequent drive connection component 9.
[0036] Specifically, the vertical rotation of the rotating shaft 6 can be synchronously converted into the horizontal rotation of the linkage shaft 83 through the linkage component 8, which provides effective power transmission for the subsequent connecting component 9 to drive the spray component 5 to adjust the angle in the vertical direction, so that the entire angle adjustment mechanism can operate in a coordinated manner.
[0037] In one embodiment of this application, such as Figure 6 As shown, the connecting assembly 9 includes a connecting shaft 91, a connecting seat 92, a connecting frame 93, a connecting rod 94, and a second drive disk 95. The connecting shaft 91 is disposed within the connecting frame 93 and is movably disposed within the connecting seat 92. One end of the connecting rod 94 is rotatably disposed on the connecting frame 93, and the other end of the connecting rod 94 is eccentrically disposed on the second drive disk 95.
[0038] It should be noted that the connecting seat 92 is rotatably mounted on the support frame 52 via a bearing, and the connecting shaft 91 passes through the connecting seat 92, allowing it to rotate and slide flexibly inside. The connecting frame 93 is fixedly connected to the connecting shaft 91, so that when the support frame 52 rotates, the connecting shaft 91 can slide accordingly, thereby avoiding motion interference.
[0039] One end of the connecting rod 94 is rotatably connected to the connecting frame 93 via a pin, and the other end is eccentrically rotated on the second drive disc 95 via a pin. The second drive disc 95 is fixedly connected to the linkage shaft 83.
[0040] Based on this, when the linkage shaft 83 rotates under the drive of the linkage component 8, it will drive the second drive disk 95 to rotate. The second drive disk 95 drives the connecting rod 94 to reciprocate. The connecting rod 94 pulls the connecting frame 93. The connecting frame 93 drives the connecting seat 92 through the connecting shaft 91, and then drives the support frame 52 of the spray component 5 to pitch around the axis of the support shaft 51 through the connecting seat 92, thereby adjusting the spray angle of the spray component 5 in the vertical direction.
[0041] Understandably, driven by the second drive disc 95 and the connecting rod 94, the connecting rod 94 reciprocates, which in turn drives the spray assembly 5 to swing back and forth around the support shaft 51. Through this reciprocating swinging motion, the spray can form a fan-shaped coverage area in the vertical direction. By combining this with the fan-shaped coverage area in the horizontal direction, the overall coverage range of the spray is further expanded, enabling the disinfection spray device to cover the target area more comprehensively and efficiently during disinfection operations, reducing blind spots and improving the disinfection effect.
[0042] In practical applications, when disinfection operations are required, the operator first pushes the disinfection spray device to the target location (such as an indoor space, outdoor area, or public place that needs to be disinfected), and then starts the delivery pump 3. The delivery pump 3 delivers the liquid disinfectant medium in the storage tank 2 to the atomizing nozzle 55. The atomizing nozzle 55 atomizes the liquid disinfectant medium into tiny droplets. At the same time, the fan 53 starts, and the airflow it generates drives the droplets to spread in all directions.
[0043] The drive unit 77 is started synchronously. The drive unit 77 drives the first drive disk 75 to rotate. The first drive disk 75 drives the drive rod 74 to make eccentric motion. The drive rod 74 drives the toothed plate 72 through the sliding seat 73. The toothed plate 72 drives the toothed ring 71 to rotate through the teeth. The toothed ring 71 drives the rotating shaft 6. The rotating shaft 6 drives the spray assembly 5 to reciprocate in the horizontal direction, so that the spray forms a fan-shaped coverage area in the horizontal direction.
[0044] At the same time, when the rotating shaft 6 rotates, it will drive the support plate 84 to rotate synchronously. With the cooperation of the first bevel gear 81 and the second bevel gear 82, the linkage shaft 83 drives the second drive disk 95 to rotate. The second drive disk 95 drives the connecting rod 94 to reciprocate, thereby driving the spray assembly 5 to pitch around the axis of the support shaft 51, so that the spray forms a fan-shaped coverage area in the vertical direction.
[0045] By combining horizontal and vertical angle adjustments, the spray coverage is significantly increased, enabling more comprehensive and efficient coverage of the target area and reducing blind spots in disinfection.
[0046] In summary, the disinfection and sterilization spray device of this application embodiment, by setting an azimuth adjustment component, uses a driving component to drive the first driving disc to rotate. Through the cooperation of structures such as the driving rod, sliding seat, toothed plate, and toothed ring, the spray component is driven to swing back and forth in the horizontal direction, forming a fan-shaped coverage area, which effectively expands the coverage range of the spray in the horizontal direction. At the same time, by setting a linkage component, the rotational motion of the rotating shaft is converted into the rotation of the linkage shaft. Then, through the cooperation of structures such as the second driving disc and connecting rod, the spray component is made to pitch around the support shaft, which also forms a fan-shaped coverage area. Through this multi-dimensional swinging spraying method, the coverage range of the spray is greatly increased, the coverage blind spots are reduced, and the movement frequency of the equipment is reduced. This enables the disinfection and sterilization spray device to adapt to the disinfection needs in large-area disinfection scenarios and improves the efficiency of disinfection operations.
