Description

Technical Field

[0001] The invention relates to the technical field of disinfection boxes, in particular to a disinfection box with a disinfectant spraying angle self-adjusting function. Background Art

[0002] With the improvement of public health awareness and the growing demand for clean environment, disinfection technology has been widely used in medical, food processing and public places. Traditional disinfection methods are mainly manual, inefficient and have the risk of human omissions. In order to meet the needs of efficient and comprehensive disinfection, automated and intelligent disinfection equipment has begun to appear on the market. These devices are developing in the direction of integrating multiple functions and improving disinfection effects, and have broad application prospects.

[0003] Current automatic disinfection equipment usually uses ultraviolet irradiation, ozone disinfection or a simple spraying system to disinfect the surface of items. These devices may be equipped with automatic door opening and closing, basic temperature control and timing functions to improve the convenience of operation. Some devices also use fixed-angle nozzles to spray disinfectant on items, but the spraying range and angle adjustment capabilities are limited, making it difficult to achieve full-scale disinfection.

[0004] Existing disinfection equipment has deficiencies in synchronous operation and disinfection efficiency. It is impossible to achieve the synchronization of the opening of the box door and the pre-spraying of the disinfectant, which makes cross-contamination possible. In addition, the angle of the spraying mechanism is fixed and cannot be adjusted according to the shape and position of the object, which easily leads to disinfection dead corners. The amount of disinfectant is not accurately controlled, which may cause waste or incomplete disinfection. The temperature control system also lacks precise adjustment of temperature and ultraviolet intensity, which affects the optimization of the disinfection environment. The above problems limit the disinfection effect and resource utilization efficiency of the disinfection equipment. Therefore, those skilled in the art provide a disinfection box with a self-adjusting function for the spraying angle of the disinfectant. Summary of the invention

[0005] The purpose of the present invention is to provide a disinfection box with a disinfectant spraying angle self-adjusting function to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

The temperature control mechanism and the angle adjustment mechanism are fastened together, the positioning mechanism and the box body are fastened together, the angle adjustment mechanism and the positioning mechanism are fastened together, the spraying mechanism and the angle adjustment mechanism are fastened together, the transmission assembly and the spraying mechanism are transmission-connected, the transmission assembly and the box door are transmission-connected, the transmission assembly and the box body are fastened together, and the box door and the box body are hinged.

[0008] By adopting the above technical solution, when the transmission component is started, the gear meshing transmission drives the box door to open or close, and drives the spraying mechanism to spray the disinfectant. At the same time, the quantitative spraying of the spraying mechanism is reset by opening the door. The angle adjustment mechanism can adjust the spraying angle of the spraying mechanism. The temperature control mechanism adjusts the temperature inside the box to provide the best disinfection environment. The positioning mechanism is used to fix the position of the items to be disinfected to prevent them from moving during the disinfection process. Through the above design, the synchronous operation of the box door opening and the spraying mechanism is realized, achieving an efficient and comprehensive disinfection effect.

[0009] Furthermore, the transmission assembly includes an opening and closing motor, a transmission gear, a gear rod, an inner ratchet, an outer ratchet, a rack, a transmission belt and a driven gear.

When the box door is opened or closed, the spraying mechanism is synchronously restored to achieve the effect of controlling the quantitative amount of the disinfectant, thereby improving the disinfection efficiency and reducing the loss of the disinfectant.

[0012] By adopting the above technical solution, the spraying mechanism realizes precise control and efficient spraying of disinfectant through the combination of pre-spraying assembly, quantitative spraying assembly and spray nozzle assembly. The pre-spraying assembly is tightly connected to the box body and driven by the driven gear. It automatically performs pre-spraying when the box door is opened to ensure that the disinfectant can cover the items to be disinfected at the first time, and at the same time disinfect the items disinfected last time to prevent cross contamination when they are taken out by clamping. The quantitative spraying assembly is connected to the inner ratchet transmission to ensure that the amount of disinfectant sprayed each time is accurate and consistent. The spray nozzle assembly cooperates with the angle adjustment mechanism to flexibly adjust the spraying angle to achieve a full range of disinfection effects without dead ends. Through the above design, the disinfection efficiency is improved and the comprehensiveness and reliability of the disinfection process are ensured.

[0013] Furthermore, the pre-spraying assembly includes a pre-spraying box, a pre-spraying nozzle, a magnetic strip, an opening and closing gear and a baffle plate.

[0014] By adopting the above technical solution, the pre-spraying component uses the magnetic strip to attract the magnetic poles of the box door. When the box door is opened, the magnetic strip triggers the pre-spraying nozzle to start working, realizing the automatic pre-spraying function. The opening and closing gear is driven by the driven gear to drive the semi-crescent-shaped baffle plate to rotate, controlling the opening and closing of the pre-spraying box, thereby accurately controlling the time and dosage of the pre-spraying. This design can perform preliminary disinfection on the items at the moment the box door is opened, thereby improving the timeliness and effectiveness of the disinfection process.

[0015] Furthermore, the quantitative spraying assembly includes a floating plate, a float, a sliding rod, a movable plate, a quantitative box, a spray box and a metering pump. The rack and the movable plate are drivingly connected, the sliding rod and the floating plate are fastened together, the sliding rod and the movable plate are fastened together, the float and the floating plate are fastened together, the quantitative box and the box body are fastened together, the floating plate and the quantitative box are slidingly connected, the spray box and the quantitative box are fastened together, the metering pump and the spray box are fastened together, the metering pump and the spray box are connected together, and the metering pump and the quantitative box are connected together.

[0016] By adopting the above technical solution, the quantitative spraying assembly drives the moving plate through the rack to move the sliding rod and the floating plate up and down, adjust the capacity of the disinfectant in the quantitative box, and the float is tightly connected to the floating plate to monitor the liquid level in real time. The metering pump accurately controls the output of the disinfectant in the spray box according to the feedback of the float. Through this combination of mechanical and liquid level feedback, the amount of disinfectant sprayed each time is ensured to be consistent, avoiding excess or insufficient amount, and improving the utilization rate of the disinfectant.

[0018] By adopting the above technical solution, the spray nozzle assembly drives the vertical gear and the horizontal gear through the vertical motor and the horizontal motor, so that the spray nozzle body can be flexibly adjusted in multiple directions; the design of the ball gear enables the movement of the vertical gear and the horizontal gear to be synchronously transmitted to the spray nozzle body, thereby realizing the spraying angle adjustment in three-dimensional space; the application of the angle block ensures the stability of the spray nozzle body when adjusting the angle, avoiding spraying deviation; through precise angle control, full coverage spraying of the items to be disinfected is achieved.

[0019] Furthermore, the angle adjustment mechanism includes an angle box, an angle motor, an angle rod, an articulated block, a ball rod, a connecting block, a connecting rod and a rotating block.

[0020] By adopting the above technical solution, when the angle motor is started, the angle rod is driven to rotate, and the rotation of the angle rod causes the ball rod to swing around the connection point through its rotational connection with the ball rod. The swing of the ball rod is transmitted to the hinge block through the rotational connection with the hinge block, and the hinge block transmits the movement to the connection block through the rotational connection with the connection block. Since the connection block and the angle box are also rotationally connected, the entire mechanical structure can be flexibly adjusted. The rotating block is fastened to the ball rod and moves with the swing of the ball rod, driving the spray nozzle body fastened thereto to change its angle. The rotational connection between the linkage rod and the spray nozzle body ensures the stability and positioning accuracy of the spray nozzle body during the angle adjustment process. The rotational motion of the angle motor is used to transmit and convert the power into the angle adjustment of the spray nozzle body through a series of rotationally connected rods (angle rod, ball rod, hinge block, connection block). This mechanical transmission relationship enables the spray nozzle body to accurately adjust the angle in multiple dimensions to adapt to the shape and position of the objects to be disinfected. Through the above structural design, the spray nozzle body can flexibly adjust the spraying angle to achieve all-round and dead-angle disinfection of the objects. The angle adjustment mechanism ensures that the spray nozzle body moves smoothly and accurately during the adjustment process, thereby improving the spraying effect and disinfection efficiency of the disinfectant and ensuring the comprehensiveness and reliability of the disinfection process.

[0022] By adopting the above technical scheme, the temperature control mechanism realizes all-round irradiation of the inside of the box with ultraviolet rays through the combination of ultraviolet light source and reflector, thereby enhancing the disinfection effect. The light control motor adjusts the position and angle of the reflector to control the intensity and coverage of the ultraviolet lamp. The cooperation of the heater, cooler and fan allows the air inside the box to circulate through the air guide cover and spiral air guide groove to accurately control the temperature. The design of the exhaust port ensures the temperature circulation of the box and provides a stable disinfection environment. On the other hand, the guidance of the air guide groove during the spraying process effectively controls the temperature while guiding the adhesion of the disinfectant spray. When spraying from the top, the fan at the bottom starts to guide, and when spraying from the bottom, the fan at the top starts to guide.

[0023] Furthermore, the positioning mechanism includes an annular guide rail, a slider, a clamping hydraulic cylinder, a supporting plate, a first elastic member, an electromagnetic block, an abutment column, a pressure sensor and an opening and closing plate.

[0056] By adopting the above technical solution, when the angle motor 42 is started, the angle rod 43 is driven to rotate, and the rotation of the angle rod 43 causes the ball rod 45 to swing around the connection point through its rotation connection with the ball rod 45. The swing of the ball rod 45 is transmitted to the hinge block 44 through the rotation connection with the hinge block 44, and the hinge block 44 transmits the movement to the connection block 46 through the rotation connection with the connection block 46. Since the connection block 46 and the angle box 41 are also rotationally connected, the entire mechanical structure can be flexibly adjusted. The rotating block 48 is fastened to the ball rod 45, and moves with the swing of the ball rod 45, driving the spray nozzle body 531 fastened thereto to change the angle. The rotation connection between the linkage rod 47 and the spray nozzle body 531 ensures the stability and positioning accuracy of the spray nozzle body 531 during the angle adjustment process. The rotational motion of the angle motor 42 is used to transmit and convert the power into the angle adjustment of the spray nozzle body 531 through a series of rotationally connected rods (angle rod 43, ball rod 45, hinge block 44, connection block 46). This mechanical transmission relationship enables the spray nozzle body 531 to accurately adjust the angle in multiple dimensions to adapt to the shape and position of the object to be disinfected. Through the above structural design, the spray nozzle body 531 can flexibly adjust the spraying angle to achieve all-round and dead-angle disinfection of the object. The angle adjustment mechanism 4 ensures that the spray nozzle body 531 moves smoothly and is accurately positioned during the adjustment process, thereby improving the spraying effect and disinfection efficiency of the disinfectant and ensuring the comprehensiveness and reliability of the disinfection process.

The heater 64, the cooler 65 and the fan 66 cooperate to circulate the air inside the box 1 through the air guide cover 67 and the spiral air guide groove 671, so as to accurately control the temperature. The design of the exhaust port 11 ensures the temperature circulation of the box 1 and provides a stable disinfection environment. On the other hand, the guidance of the air guide groove 671 during the spraying process effectively controls the temperature while guiding the adhesion of the sprayed disinfectant. When spraying from the top, the fan 66 at the bottom starts to guide, and when spraying from the bottom, the fan 66 at the top starts to guide.
