Description

Technical Field

[0001] This utility model relates to a non-contact disinfection device, belonging to the field of medical equipment technology. Background Technology

[0002] Currently, the demand for contactless disinfection of hands and items is increasing in medical, public, and home environments. Traditional disinfection devices mostly adopt press-type or sensor-type designs, but they still have certain limitations. For example, press-type devices require manual operation, posing a risk of cross-contamination; while sensor-type devices can achieve contactless operation, their structure is complex, their cost is high, and their adaptability to the usage environment is poor. After searching, a Chinese patent with publication number CN221867095U was found to disclose a foot-operated disinfection device that can be drilled without drilling. In this patent, when the user presses the pedal, the pedal rotates around the pivot point between its middle part and the support, causing the end away from the elastic element to rise, driving the first and second transmission rods to move upward; the transmission rod pushes the long end of the pressing rod upward, using the lever principle to press down the switch of the disinfectant storage device, triggering the disinfectant to spray out; after releasing the pedal, the bottom elastic element rebounds to reset the pedal, the transmission rod descends accordingly, the short end of the pressing rod rises to release the switch, and the device returns to its initial state. However, this patent has many mechanical parts, and long-term stepping on it can easily lead to wear or jamming of the connecting parts, resulting in high maintenance costs; long-term pressing of the pump nozzle of the disinfectant storage device may damage the pump nozzle and increase the cost of use. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a non-contact disinfection device that can achieve non-contact control, simplify the mechanical structure, reduce maintenance costs, reduce direct pressure on the disinfectant storage device, and extend the service life of the equipment.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a non-contact disinfection device, comprising:

[0005] Support base;

[0006] A support bracket, which is mounted on the support base;

[0007] A storage tank is mounted on the support bracket. The storage tank has a storage cavity suitable for storing disinfectant. A nozzle is provided at the bottom of the storage tank. A pressure pump is provided in the storage cavity and connected to the nozzle.

[0008] The storage tank is equipped with a contact switch on top, which is connected to the pressurizing pump. The contact switch has an upper sensing part and a lower sensing part, which are hinged together. A return spring is provided between the upper sensing part and the lower sensing part.

[0009] A foot pedal drive assembly includes a foot pedal frame and at least one connecting rope. The foot pedal frame is hinged to the support base. One end of the connecting rope is connected to the foot pedal frame, and the other end of the connecting rope is connected to the upper sensing part. The foot pedal frame is adapted to rotate downward along the hinge point to drive the connecting rope to move downward, thereby driving the upper sensing part to rotate towards the lower sensing part.

[0010] Furthermore, in order to achieve automated operation, a contactless disinfection device also includes a controller, which is mounted on the support bracket and is connected to the contact switch and the pressure pump respectively. When the upper sensing part is rotated downward under pressure and the distance between it and the lower sensing part is less than a preset value, it sends a signal to the controller. After receiving the signal, the controller controls the pressure pump to spray disinfectant from the nozzle.

[0011] Furthermore, in order to detect the remaining amount of disinfectant in the storage tank in real time, a level gauge suitable for detecting the disinfectant level is also provided in the storage chamber. The level gauge is connected to the controller and is suitable for transmitting the disinfectant level data in the storage chamber to the controller.

[0012] Furthermore, to allow operators to intuitively understand the remaining status of the disinfectant, a contactless disinfection device also includes an indicator light, which includes a red LED and a green LED. The indicator light is connected to the controller. When the level gauge detects that the disinfectant level in the storage chamber is lower than a preset threshold, the controller controls the green LED to turn off and the red LED to remain on.

[0013] When the disinfectant level is higher than or equal to a preset threshold, the controller turns off the red LED and keeps the green LED on.

[0014] Furthermore, a counterweight is provided at the end of the foot pedal away from the connecting rope.

[0015] Furthermore, the connecting rope is a nylon rope.

[0016] Furthermore, to facilitate the adjustment of the equipment height, the bottom of the support base is provided with four adjustment seats, each with an adjustment hole. A movable foot cup is rotatably installed in the adjustment hole. The movable foot cup has a connecting part and a supporting part, which are integrally formed. The adjustment hole has an internal thread, and the connecting part has an external thread that matches the internal thread.

[0017] Furthermore, the bottom of the support is provided with an anti-slip rubber pad.

[0018] Furthermore, to facilitate the adjustment of the tension of the connecting rope, a non-contact disinfection device also includes at least one tensioning component. The tensioning component includes a lead screw and nut pair and a tensioning wheel. The lead screw in the lead screw and nut pair is mounted on the support bracket, and the nut in the lead screw and nut pair is mounted on the tensioning wheel. The tensioning wheel faces the connecting rope, and the surface of the tensioning wheel is provided with a V-shaped guide groove that contacts the connecting rope. Turning the lead screw drives the tensioning wheel to move to abut against the connecting rope and adjust the tension of the connecting rope.

[0019] After adopting the above technical solution, this utility model has the following beneficial effects:

[0020] 1. In this utility model, ensure that the disinfection device is installed correctly and that the storage tank contains an appropriate amount of disinfectant. When the user needs to perform disinfection, step on the foot pedal and drive the upper sensing part to rotate downwards through the connecting rope, approaching the lower sensing part, so that the contact switch closes and sends a signal to the controller. After receiving the signal, the controller controls the pressurization pump to start, and the disinfectant sprays out from the nozzle. The user can place their hands or items to be disinfected under the nozzle for disinfection.

[0021] When disinfection is no longer needed, release the foot pedal. The counterweight will cause the foot pedal to rotate in the opposite direction, which will release the contact switch and stop disinfection.

[0022] 2. In this utility model, the level gauge monitors the remaining amount of disinfectant in real time, and the controller determines whether the disinfectant is sufficient based on the level gauge data and controls the status of the indicator light. Users can understand the remaining amount of disinfectant through the indicator light color. Staff can also adjust the adjustment seat at the bottom of the support base to adapt to different height requirements. Attached Figure Description

[0033] The foot pedal drive assembly includes a foot pedal frame 51 and at least one connecting rope 52. The foot pedal frame 51 is hinged to the support base 1. One end of the connecting rope 52 is connected to the foot pedal frame 51, and the other end of the connecting rope 52 is connected to the upper sensing part 41. The foot pedal frame 51 is adapted to rotate downward along the hinge point to drive the connecting rope 52 to move downward, thereby driving the upper sensing part 41 to rotate at the lower sensing part 42.

[0034] Specifically, such as Figure 1-3 As shown, a contactless disinfection device also includes a controller 6, which is mounted on a support bracket 2. The controller 6 is connected to a contact switch and a pressure pump 33. When the upper sensing part 41 is rotated downward under pressure and the distance between it and the lower sensing part 42 is less than a preset value, it sends a signal to the controller 6. After receiving the signal, the controller 6 controls the pressure pump 33 to spray disinfectant from the nozzle 32.

[0035] Specifically, such as Figure 4 As shown, the storage chamber 31 is also equipped with a level gauge 71 suitable for detecting the level of disinfectant. The level gauge 71 is connected to the controller 6 and is suitable for transmitting the level data of disinfectant in the storage chamber 31 to the controller 6.

[0036] Specifically, such as Figure 1-3 As shown, a contactless disinfection device also includes an indicator light 72, which includes a red LED and a green LED. The indicator light 72 is connected to the controller 6. When the level gauge 71 detects that the level of disinfectant in the storage chamber 31 is lower than a preset threshold, the controller 6 controls the green LED to turn off and the red LED to stay on.

[0037] When the disinfectant level is higher than or equal to the preset threshold, the controller 6 controls the red LED to turn off and the green LED to stay on.

[0038] In this embodiment, the level gauge 71 monitors the remaining amount of disinfectant in real time. The controller 6 determines whether the disinfectant is sufficient based on the data from the level gauge 71 and controls the status of the indicator light 72. Users can understand the remaining amount of disinfectant by the color of the indicator light 72.

[0039] Specifically, such as Figure 1-3 As shown, a counterweight 53 is provided at the end of the footrest 51 away from the connecting rope 52.

[0040] Specifically, the connecting rope 52 is a nylon rope.

[0041] Specifically, such as Figure 1-3 As shown, the bottom of the support base 1 is provided with four adjustment seats 81. Each adjustment seat 81 has an adjustment hole. A movable foot cup is rotatably installed in the adjustment hole. The movable foot cup has a connecting part 82 and a support part 83. The connecting part 82 and the support part 83 are integrally set. The adjustment hole has an internal thread, and the connecting part 82 has an external thread that matches the internal thread.

[0042] Specifically, the bottom of the support part 83 is provided with an anti-slip rubber pad.

[0043] Specifically, such as Figure 1-3 As shown, a contactless disinfection device also includes at least one tensioning component. The tensioning component includes a lead screw and nut pair and a tensioning wheel 92. The lead screw 91 in the lead screw and nut pair is mounted on the support bracket 2, and the nut in the lead screw and nut pair is mounted on the tensioning wheel 92. The tensioning wheel 92 faces the connecting rope 52. The surface of the tensioning wheel 92 is provided with a V-shaped guide groove that contacts the connecting rope 52. Turning the lead screw 91 drives the tensioning wheel 92 to move to abut against the connecting rope 52 and adjust the tension of the connecting rope 52.

[0044] In this embodiment, the disinfection device is installed correctly and the storage tank 3 contains an appropriate amount of disinfectant. When the user needs to perform disinfection, he steps on the foot pedal 51, and the upper sensing part 41 rotates downward through the connecting rope 52 and approaches the lower sensing part 42, so that the contact switch closes and sends a signal to the controller 6. After receiving the signal, the controller 6 controls the pressurization pump 33 to start, and the disinfectant sprays out from the nozzle 32. The user can place his hands or the items to be disinfected under the nozzle 32 for disinfection.

[0045] When disinfection is no longer needed, release the foot pedal 51. The counterweight 53 will cause the foot pedal 51 to rotate in the opposite direction, which will release the contact switch and stop the disinfection.
