[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] like Figure 1-Figure 4 As shown, a screening instrument with automatic disinfection function includes a screening body 1, an upper inspection plate 2, a lower inspection plate 3, a disinfection mechanism and a driving assembly; the screening body 1 is provided with an upper mounting groove 11, the upper inspection plate 2 is slidably mounted in the upper mounting groove 11, and the lower inspection plate 3 is arranged at the bottom of the screening body 1; the disinfection mechanism is arranged at the screening body 1, and is located between the upper inspection plate 2 and the lower inspection plate 3; the upper inspection plate 2 is used to place the hands of the examinee, and is designed to be slidably mounted in the upper mounting groove 11, so that the upper inspection plate 2 can be folded up after use. The lower inspection plate 3 is directly arranged at the bottom of the screening body 1, and is used to place the feet of the examinee;

[0028] The driving component is arranged on the side wall of the upper mounting plate and is slidably connected with the disinfection mechanism. When the upper inspection plate 2 slides into the upper mounting groove 11, the driving component drives the disinfection mechanism to reciprocate and disinfect the upper inspection plate 2 and the lower inspection plate 3 at the same time; when the upper inspection plate 2 is used, the operator pushes the upper inspection plate 2 toward the mounting groove, and at the same time, the driving component and the upper inspection plate 2 instruments move synchronously, and the first driving plate 51 and the second driving plate 52 move in the mounting groove. When the driving component moves into the mounting groove, it is continuously slidably connected with the disinfection mechanism. Under the action of the sliding groove 6, the first driving plate 51 and the second driving plate 52 will drive the disinfection mechanism to perform a reciprocating spraying action, and then the disinfection mechanism releases the disinfectant to comprehensively and evenly disinfect the upper inspection plate 2 and the lower inspection plate 3.

[0029] The structure of the driving assembly includes a first driving plate 51 and a second driving plate 52, which are respectively installed on the left and right side walls of the upper inspection plate 2, and sliding grooves 6 are provided at both left and right ends of the first driving plate 51 and the second driving plate 52, and the sliding grooves 6 are used to guide the disinfection mechanism to perform reciprocating extrusion motion; as the first driving plate 51 and the second driving plate 52 move, the sliding grooves 6 begin to produce relative displacement with the disinfection mechanism. Since the sliding groove 6 is designed as a multi-stage repeated structure, the disinfection mechanism can perform multiple spraying actions to achieve comprehensive disinfection of the first inspection plate and the second inspection plate; the disinfection mechanism realizes up and down movement at the current position under the guidance of the sliding groove 6 of the first drive plate 51 and the second drive plate 52. During the up and down movement, the disinfection mechanism will release disinfectant to comprehensively and evenly disinfect the upper and lower inspection plates 3; in short, the operator only needs to simply push and pull the upper inspection plate 2 to simultaneously drive the disinfection mechanism to reciprocate and complete the disinfection operation without additional manual operation or adjustment, which greatly simplifies the operation process; through the guiding effect of the sliding groove 6, the disinfection mechanism can realize reciprocating motion in the vertical direction, thereby ensuring that the disinfectant can evenly and fully cover the entire board surface, thereby improving the disinfection effect.

[0030] In one embodiment, the sliding groove 6 is a structure with at least two crests and troughs, and any crest and trough are adjacent; when the operator pushes and pulls the upper inspection plate 2, the first drive plate 51 and the second drive plate 52 move accordingly, driving the sliding groove 6 thereon to contact the disinfection mechanism. Due to the crest and trough design of the sliding groove 6, the disinfection mechanism will move along the crest to the trough when squeezed. When the disinfection mechanism moves to the crest, it will be guided by the sliding groove 6 and begin to transition downward to the adjacent trough. When the disinfection mechanism reaches the trough, it will be guided by the sliding groove 6 again and begin to transition upward to the next crest; in this way, the disinfection mechanism forms a continuous reciprocating motion between the crests and troughs; in the process of the disinfection mechanism reciprocating along the crests and troughs of the sliding groove 6, it will continuously squeeze and release the upper and lower inspection plates 3, thereby releasing the disinfectant and achieving comprehensive disinfection of the plate surface.

[0031] In one embodiment, the disinfection mechanism includes a liquid storage box 41 and an upper disinfection assembly 42; the liquid storage box 41 is arranged on the screening body 1, and the liquid storage box 41 is two upper and lower accommodating spaces that are not connected to each other. The liquid suction end of the upper disinfection assembly 42 is connected to the upper part of the liquid storage box 41, and the liquid outlet end of the upper disinfection assembly 42 is arranged at one end of the upper mounting groove 11 close to the upper inspection plate 2; the upper disinfection assembly 42 is slidably connected to the first driving plate 51, and the first driving plate 51 is used to drive the upper disinfection assembly 42 to disinfect the upper inspection plate 2; the upper accommodating space is used to store the disinfectant to be used, and is connected to the upper disinfection assembly 42 through a specific pipeline; the liquid suction end of the upper disinfection assembly 42 is connected to the upper part of the liquid storage box 41, and the disinfectant is extracted from the liquid storage box 41 and transported to the liquid outlet end by using a pressure difference mechanism similar to that in a spray bottle. The liquid outlet end is arranged at one end of the upper mounting groove 11 close to the upper inspection plate 2 to ensure that the disinfectant can be directly and accurately sprayed onto the surface of the upper inspection plate 2. When the inspection is completed, the upper inspection plate 2 is pushed back into the installation slot. At this time, the first drive plate 51 moves forward with the upper inspection plate 2. When the first drive plate 51 moves inward, the wave crests and wave joints of the sliding groove 6 continuously guide the upper disinfection component 42 to perform an up and down squeezing movement. In this process, the liquid outlet end of the upper disinfection component 42 continuously sprays disinfectant to cover and wet the entire surface of the upper inspection plate 2; further, during the disinfection,

[0032] After the liquid spraying is completed, the upper inspection plate 2 may need to be further processed through an air drying system to remove residual liquid and ensure that the surface is dry and free of dirt.

[0033] In one embodiment, the disinfection mechanism also includes a lower disinfection component 43, the liquid suction end of the lower disinfection component 43 is connected to the lower portion of the liquid storage box 41, and the liquid outlet end of the lower disinfection component 43 is arranged at the front end of the lower inspection plate 3; the lower disinfection component 43 is slidably connected to the second drive plate 52, and the second drive plate 52 is used to drive the lower disinfection component 43 to disinfect the lower inspection plate 3; the lower disinfection component 43 is consistent with the upper disinfection component 42 in principle and will not be repeated.

[0034] In one embodiment, the upper disinfection assembly 42 includes a first liquid outlet pipe 421, a first sealing member 422, a first piston member 423 and a first toggle rod 424; the first liquid outlet pipe 421 is fixed to the groove wall of the mounting groove, the first liquid outlet pipe 421 is connected to the upper part of the liquid storage box 41, and the piston chamber of the first piston member 423 is connected to the first liquid outlet pipe 421; the front end of the first toggle rod 424 is hinged to the first liquid outlet pipe 421, the first toggle rod 424 is slidably connected to the first piston member 423, the rear end of the first toggle rod 424 is slidably connected to the sliding groove 6 of the first driving plate 51, and the first piston member 423 is used to change the pressure in the first liquid outlet pipe 421; the first liquid outlet pipe 421 is fixed to the groove wall of the mounting groove and is connected to the upper part of the liquid storage box 41, ensuring that the disinfectant can flow smoothly from the liquid storage box 41 into the first liquid outlet pipe 421. The piston cavity of the first piston member 423 is connected to the first liquid outlet pipe 421, forming a space that can be sealed and change the internal pressure. The front end of the first toggle rod 424 is hinged to the first liquid outlet pipe 421, allowing the first toggle rod 424 to rotate relative to the first liquid outlet pipe 421 within a certain range. The first toggle rod 424 is slidably connected to the first piston member 423. This design enables the first piston member 423 to slide in the piston cavity when the first toggle rod 424 moves. The rear end of the first toggle rod 424 is slidably connected to the sliding groove 6 of the first driving plate 51, ensuring that the first driving plate 51 can drive the first toggle rod 424 to move; the sliding groove 6 drives the first toggle rod 424 to move up and down. The movement of the first toggle rod 424 causes the first piston member 423 to slide in the piston cavity, thereby increasing the pressure in the first liquid outlet pipe 421, forcing the disinfectant to spray out from the outlet of the first liquid outlet pipe 421 (i.e., the end close to the upper inspection plate 2), thereby achieving the spraying of the disinfectant.

[0035] In one embodiment, the lower disinfection assembly 43 includes a second liquid outlet pipe 431, a second sealing member 432, a second piston member 433 and a second toggle rod 434; the second liquid outlet pipe 431 is fixed at the bottom of the screening body 1 and corresponds to the lower inspection plate 3, the second liquid outlet pipe 431 is connected to the lower part of the liquid storage box 41, and the piston chamber of the second piston member 433 is connected to the second liquid outlet pipe 431; the front end of the second toggle rod 434 is hinged to the second liquid outlet pipe 431, the middle end of the second toggle rod 434 is slidingly connected to the second piston member 433, and the rear end of the second toggle rod 434 is slidingly connected to the sliding groove 6 of the second driving plate 52 through the connecting rod 435, and the second piston member 433 is used to change the pressure in the second liquid outlet pipe 431; the second liquid outlet pipe 431 is fixed at the bottom of the screening body 1 and corresponds to the lower inspection plate 3, ensuring that the disinfectant can be directly sprayed onto the surface of the lower inspection plate 3. The second liquid outlet pipe 431 is connected to the lower part of the liquid storage box 41, so that the disinfectant can flow into the second liquid outlet pipe 431 from the lower part of the liquid storage box 41. The piston cavity of the second piston member 433 is connected to the second liquid outlet pipe 431, forming a space that can be sealed and change the internal pressure; the front end of the second toggle rod 434 is hinged to the second liquid outlet pipe 431, allowing the second toggle rod 434 to rotate relative to the second liquid outlet pipe 431 within a certain range; the middle end of the second toggle rod 434 is slidably connected to the second piston member 433, and this design enables the second piston member 433 to slide in the piston cavity when the second toggle rod 434 moves; the rear end of the second toggle rod 434 is slidably connected to the sliding groove 6 of the second drive plate 52 through the connecting rod 435, ensuring that the second drive plate 52 can drive the second toggle rod 434 to move; The sliding groove 6 and the connecting rod 435 drive the second toggle rod 434 to move; the movement of the second toggle rod 434 causes the second piston member 433 to slide in the piston cavity, thereby increasing the pressure in the second liquid outlet pipe 431, forcing the disinfectant to be sprayed out from the outlet of the second liquid outlet pipe 431 (i.e., one end close to the lower inspection plate 3), thereby achieving the spraying of the disinfectant on the lower inspection plate 3; it is worth noting that the first drive plate 51 and the second drive plate 52 are respectively installed on both sides of the upper inspection plate 2. When the upper inspection plate 2 is used up, it is necessary to retract the upper inspection plate 2 into the installation groove. Therefore, in the process of retracting the upper inspection plate 2 into the installation groove, the disinfection assembly can be driven to disinfect the upper inspection plate 2 and the lower inspection plate 3 at the same time.

[0036] In one embodiment, the first seal 422 and the second seal 432 have the same structure, and both the first seal 422 and the second seal 432 include a spring and a ball valve; the spring is arranged at the outlet end of the liquid storage box 41, and the ball valve and the spring are connected to block the outlet end of the liquid storage box 41; under normal circumstances, the spring is in a compressed state, and the ball valve is tightly pressed against the outlet port of the liquid storage box 41, forming an effective sealing barrier. Due to the elastic force of the spring, the ball valve can maintain a tight fit even in the absence of external pressure to prevent the disinfectant from leaking; when the disinfectant needs to be sprayed, the piston member of the upper disinfection assembly 42 or the lower disinfection assembly 43 will suck the disinfectant in the liquid storage box 41. As the piston member moves backward, the pressure at the outlet port of the liquid storage box 41 decreases, and the elastic force of the spring overcomes the gravity or external pressure of the ball valve, lifts the ball valve from the outlet port, and allows the disinfectant to flow out; when the piston member completes the suction action and starts to move forward, the pressure at the outlet port of the liquid storage box 41 gradually increases. At this time, the elastic force of the spring plus the gravity of the ball valve itself or the external pressure work together to press the ball valve back to the liquid outlet port, achieving a seal and preventing the disinfectant from continuing to flow out; during the spraying of the disinfectant, as the piston moves and the pressure of the liquid outlet port changes, the ball valve will continuously open and close to maintain the pressure balance in the system. This dynamic balance ensures the stable spraying of the disinfectant and the continuous operation of the system.

[0037] In one embodiment, the first driving plate 51 and the second driving plate 52 are both provided with a one-way motion assembly, and the one-way motion assembly is used to guide the first toggle rod 424 and the second toggle rod 434 to perform linear motion; the one-way motion assembly includes a linear groove 71 and a guide member 72; the linear groove 71 is connected to the sliding groove 6, and the linear groove 71 is located at the top of the sliding groove 6; the guide member 72 is arranged on the groove wall of the linear groove 71, and the first toggle rod 424 and the second toggle rod 434 are respectively abutted against their respective guide members 72, and the guide member 72 is used to guide the first toggle rod 424 and the second toggle rod 434 to move from the sliding groove 6 to the linear groove 71; the guide member 72 includes a guide spring 721 and a guide block 722; the guide spring 721 is connected to the guide block 722, and the guide block 722 is hinged to the groove wall of the sliding groove 6;

[0038] In the initial state, the upper inspection plate 2 is located in the installation groove. At this time, the toggle rod (taking the first toggle rod 424 as an example) is at the front end of the first driving plate 51 and is located in the sliding groove 6. Since the one-way motion component is located in the linear groove 71 and at the front end of the first toggle rod 424, when a person pushes the upper inspection plate 2 into the installation groove, the thrust generated causes the first toggle rod 424 to abut against the guide member 72. The first toggle rod 424 compresses the guide block 722, and the upper inspection plate 2 loses the thrust. Due to the guide spring 721 The elastic force of the guide spring 721 is large, and the guide block 722 is ejected. Under the elastic force of the guide spring 721, the guide block 722 provides an upward thrust to help the toggle rod to smoothly transition from the sliding groove 6 to the linear groove 71. Therefore, when the upper inspection plate 2 needs to be used and pushed out of the installation groove, since the first toggle rod 424 is located in the linear groove 71 at this time, the first toggle rod 424 slides with the linear groove 71 without generating vertical movement, which can be regarded as the first toggle rod 424 not moving.

[0039] When the use is finished, the upper inspection plate 2 is pushed back to the installation groove. At this time, the first toggle rod 424 is already at the end of the linear groove 71 away from the guide member 72, that is, the first toggle rod 424 is located at the front end of the linear groove 71. Since the linear groove 71 is connected to the sliding groove 6, under the action of the thrust, the first toggle rod 424 moves from the linear groove 71 to the sliding groove 6, so that in the process of pushing the upper inspection plate 2 back to the installation groove, the first toggle rod 424 reciprocates in the vertical direction to achieve synchronous disinfection of the upper inspection plate 2 and the lower inspection plate 3; in the above process, the actions of the first toggle rod 424 and the second toggle rod 434 are performed synchronously, so the disinfection principle of the lower inspection plate 3 is not repeated; therefore, through the setting of the one-way guide component, the disinfection component can be disinfected in time after use, and when the upper inspection plate 2 is used again, the disinfection component will not be triggered for disinfection, saving resources and optimizing the disinfection mechanism.

[0040] In one embodiment, the elastic force of the guide spring 721 is greater than the elastic force of the first piston member 423 and the second piston member 433; when the toggle rod moves to the connecting point of the sliding groove 6 and the linear groove 71, the elastic force of the guide spring 721 begins to play a key role. Since the elastic force of the guide spring 721 is greater than the elastic force of the piston member, it can overcome the resistance that may be generated by the piston member and guide the toggle rod from the sliding groove 6 to the linear groove 71; the larger elastic force of the guide spring 721 ensures that the toggle rod can smoothly enter the linear groove 71 from the sliding groove 6 and trigger the piston member to move, thereby improving the reliability and stability of the equipment.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
