Description

Technical Field

[0001] This invention relates to the field of medical disinfection equipment technology, specifically a foot disinfection device. Background Technology

[0002] Hospital isolation and protection systems are typically divided into four levels: standard precautions, Level 1 protection, Level 2 protection, and Level 3 protection, each adapted to different infection risk scenarios. Currently, in professional scenarios such as medical epidemic prevention, isolation protection, and disinfection operations, medical and epidemic prevention personnel must wear sealed protective clothing throughout their work. The feet, as a critical area directly exposed to the external environment and at the highest risk of pathogen adhesion, require targeted foot disinfection, which has become a rigid part of routine epidemic prevention and control. Traditional disinfection spraying devices often use a fixed-range spraying method, which easily leads to uneven disinfection and excessive spraying of disinfectant. This not only causes unnecessary waste of disinfectant but also easily creates a slippery surface, increasing the safety hazard of medical personnel slipping while walking. Furthermore, existing foot disinfection devices cannot flexibly adjust the dispensing area according to the different foot sizes of individuals. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention utilizes the combined action of foot pressure and reverse support to ensure that disinfectant is only dispensed from the through-hole tube A in the foot contact area during use, while the non-contact areas are automatically sealed. This adapts to different foot sizes and dispenses disinfectant only from the effective contact area, reducing ineffective spraying and material costs, thus improving the economic efficiency of disinfection. Simultaneously, it prevents excessive disinfectant spraying and seepage into the shoe opening or interior, reducing skin irritation and infection risks, and enhancing disinfection safety and comfort. It is suitable for low-risk protection scenarios, such as routine outpatient and emergency care, general ward care, and Candida auris control in intensive care units.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a foot disinfection device, comprising a shell, two sets of top plates fixedly connected to the upper end of the shell, a protective cover connected between the two sets of top plates, a sliding plate slidably connected inside the shell via symmetrically arranged vertical sliding grooves, multiple sets of through-hole pipes A with independent return springs slidably connected vertically inside the sliding plate, multiple sets of telescopic rods symmetrically fixedly connected to the lower end of the sliding plate, two sets of sealed pressurized water storage tanks installed at the lower end inside the shell, multiple sets of through-hole pipes B fixedly connected to the upper end of each of the two sets of water storage tanks, and a constant pressure liquid supply device connected to one side of each of the two sets of water storage tanks via a connecting pipe; Both sides of the inner wall of the housing are equipped with spray pipes, and multiple sets of nozzles are provided on the outer side of the two sets of spray pipes, with the output ends of the multiple sets of nozzles facing the lower end of the two sets of top plates; each top plate has a slot inside, and an inclined block slides inside the slot, with one end of the inclined block connected to a horizontal plate through a top rod.

[0005] This invention utilizes the interaction between the pressure of the foot stepping on the through-hole tube A and the independent reset structure and reverse support force. Only the through-hole tube A in the area of ​​foot contact is pressed down to conduct liquid, while the uncontacted area is automatically kept closed. It can adapt to different users' foot sizes, achieving precise matching between the disinfection area and the foot contact area, and completely solving the defects of traditional disinfection devices that have a fixed spray range and cannot adapt to different foot shapes.

[0006] The present invention further defines the technical solution as follows: Preferably, the protective cover has two sets of through holes inside, which provide precise insertion and positioning for both feet, preventing foot deviation during use, ensuring accurate alignment between the sole of the foot and the liquid outlet structure, and guaranteeing reliable disinfection. In addition, the protective cover is made of elastic material without hard edges, so it will not scratch the protective clothing or skin, making insertion and withdrawal smoother and improving operating comfort and protective safety.

[0007] Preferably, the outer diameter of the through-hole pipe A matches the inner diameter of the through-hole pipe B, ensuring that the through-hole pipe A can be smoothly inserted into the through-hole pipe B when stepped on, and that the liquid outlet path is stable and reliable. In addition, each of the multiple sets of through-hole pipes B is equipped with a normally closed one-way sealing valve, so that the valve automatically closes when there is no stepping pressure. The multiple sets of water storage tanks and the multiple sets of through-hole pipes B are all located on the same vertical plane, ensuring that the force and the direction of liquid outlet are consistent, avoiding misalignment and jamming, and improving the stability of the structure during operation.

[0008] Preferably, multiple sets of springs A are fixedly connected to the lower end of the slide plate. The other end of each set of springs A is connected to the inner wall of the housing to provide a stable rebound force. When the user lifts his foot, the slide plate automatically returns to its original position without manual operation. Furthermore, the multiple sets of springs A are located on the outside of multiple sets of telescopic rods, working in conjunction with the telescopic rods to guide the slide plate vertically, ensuring that it does not tilt or jam. This allows the liquid to be cut off simultaneously during the reset, enabling the through-hole pipe A to quickly disengage from the through-hole pipe B, and the one-way valve to close in time, stopping the liquid discharge.

[0009] Preferably, one end of each of the two sets of nozzles is connected to a flexible hose, and the other end of the two sets of flexible hoses passes through the housing and extends to the outside of the housing to be connected to the hot air blower. This can provide directional hot air to quickly dry the residual disinfectant on the soles of the feet after disinfection, preventing the soles of the shoes from becoming slippery. At the same time, the hot air circulation drying can keep the inside of the device dry and inhibit bacterial growth.

[0010] Preferably, both sets of top plates have grooves at their upper ends, the grooves matching the dimensions of the horizontal plate. Two sets of top rods are fixedly connected to the upper end of the inclined block, and the other ends of the two sets of top rods are connected to the horizontal plate. Stepping on the horizontal plate will drive the inclined block to move through the top rods, triggering the hot air flow.

[0011] Preferably, two sets of springs B are fixedly connected to the lower end of the inclined block, and a support plate is fixedly connected to the other end of the two sets of springs B. The inclined block automatically resets when the pressure is lost, and quickly returns to its original position after the user leaves, closing the flow channel. The support plate is fixedly connected to the inner wall of the shell, and the support plate provides a rigid base for the springs B, resulting in high structural strength and resistance to deformation.

[0012] Preferably, the lower end of the top plate is an arc-shaped reflective surface, and the airflow from the nozzle is reflected to form a centripetal converging airflow that directionally wraps around the feet.

[0013] Preferably, the bottom of the housing is provided with a liquid collection tank and a drain outlet. The liquid collection tank can collect residual disinfectant in a concentrated manner to prevent liquid from accumulating inside the housing, and the drain outlet can ensure smooth discharge of waste liquid, keep the inside of the device dry and clean, and reduce the risk of bacterial growth and cross-infection.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a combination of foot pressure and an independent reset structure for the through-hole tube to ensure that liquid is dispensed only from the area in contact with the foot, while the non-contact areas are automatically sealed. This completely solves the problem of fixed spray range in traditional equipment, adapts to different foot shapes, and makes disinfection more targeted. Furthermore, liquid is dispensed only from the effective contact area, reducing ineffective spraying waste, lowering consumable costs, and improving the economic efficiency of disinfection. At the same time, the liquid volume is strictly matched with the contact area to prevent excessive spraying of disinfectant and to prevent liquid from seeping into the shoe opening or inside the shoe, reducing the risk of skin irritation and infection, and improving the safety and comfort of disinfection.

[0015] This invention uses a top plate to reflect and form a centrally converging directional airflow, directing the splashed disinfectant towards the instep, ankle, and surrounding area of ​​the foot, reducing blind spots in foot spraying. The airflow also carries the disinfectant, improving the adhesion and uniformity of the liquid on the protective clothing surface, preventing rapid dripping and loss of the disinfectant, and ensuring thorough disinfection.

[0016] This invention utilizes a method where, when a person steps down on the horizontal plate, the airflow from the hot air nozzle is guided upwards along the inclined surface of the ramp and blows vertically upwards from the slot in the top plate. This directs the hot air directly onto the protective clothing on the feet, quickly drying any residual disinfectant, preventing slippery soles, and ensuring safety while walking. After the person leaves, the ramp resets and closes the airflow, allowing the hot air to circulate inside the casing, drying any remaining disinfectant, preventing bacterial growth, maintaining cleanliness, and reducing the risk of cross-infection. Furthermore, the hot air works asynchronously with the disinfection process, avoiding accelerated evaporation and neutralizing the coldness of the disinfectant, thus improving the comfort level during use.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Reference Figure 1-7 This invention provides a foot disinfection device, including a housing 1. Two sets of top plates 14 are fixedly connected to the upper end of the housing 1, and a protective cover 2 is connected between the two sets of top plates 14. The protective cover 2 has two sets of through holes inside, which provide precise insertion and positioning for both feet, preventing foot displacement during use and ensuring accurate alignment between the sole of the foot and the liquid outlet structure. The protective cover 2 is made of elastic material without hard edges, so it will not scratch protective clothing or skin. The housing 1 is connected to a sliding plate 3 through symmetrically arranged vertical grooves, ensuring that the sliding plate 3 rises and falls smoothly only in the vertical direction without tilting or deviating. The slide plate 3 is vertically slidably connected to multiple sets of through-hole tubes A4 with independent return springs. There are independent return springs between the through-hole tubes A4 and the slide plate 3, so that the through-hole tubes A4 that are not stepped on are kept in an upward retracted state. Multiple sets of telescopic rods 5 are symmetrically fixedly connected to the lower end of the slide plate 3. Springs A6 are sleeved on the outside of the telescopic rods 5. The two ends of the springs A6 are respectively connected to the slide plate 3 and the inner wall of the shell 1, which are used to provide stable rebound force and realize automatic reset after lifting the foot. Two sets of sealed pressurized water storage tanks 7 are installed at the lower end of the shell 1. Multiple sets of through-hole pipes B8 are fixedly connected to the upper end of the two sets of water storage tanks 7. Through-hole pipes A4 and B8 are arranged coaxially. A normally closed one-way sealing valve 9 is installed inside the through-hole pipe B8. It only opens when subjected to mechanical pressure and automatically closes and seals when there is no external force. The water storage tanks and multiple sets of through-hole pipes B are all located on the same vertical plane to ensure that the force and liquid outlet direction are consistent, avoid misalignment and jamming, and improve the stability of the structure. One side of the two sets of water storage tanks 7 is connected to a constant pressure liquid supply device through a connecting pipe to ensure that the water storage tanks 7 maintain a stable liquid outlet pressure. Spray pipes 12 are installed on both sides of the inner wall of the housing 1. Multiple nozzles 13 are provided on the outer side of the two sets of spray pipes 12, and the output ends of the multiple nozzles 13 face the lower end of the two sets of top plates 14. The lower end of the top plate 14 is an arc-shaped reflective surface. The airflow from the nozzles is reflected to form a centripetal converging airflow that directionally wraps around the feet. One end of each spray pipe 12 is connected to a hose. The other end of the hose passes through the housing and extends to the outside of the housing to connect with a hot air blower, which can provide directional hot air to quickly dry the residual disinfectant on the soles of the feet after disinfection, so as to avoid the soles of the shoes from being slippery. At the same time, the hot air circulation drying can keep the inside of the device dry and inhibit bacterial growth. A liquid collection tank and a drain outlet are provided at the bottom of the housing to collect and discharge the residual disinfectant. The top plate 14 has slots inside, and inclined blocks 18 are slidably installed inside the slots. One end of the inclined block 18 is connected to the horizontal plate 16 through the top rod 17. Stepping on the horizontal plate will drive the inclined block to move through the top rod, triggering the hot air guide. The upper end of the top plate 14 has a groove 15 to accommodate the horizontal plate 16, and the lower end of the top plate is an arc-shaped reflective surface. The airflow from the nozzle is reflected to form a centripetal converging airflow that is directed to wrap around the feet. The other end of the inclined block 18 is fixedly connected to a spring B19. The lower end of the spring B19 is fixed to the support plate 20. The support plate 20 is fixedly connected to the inner wall of the shell 1, so that the inclined block 18 can automatically reset upward after losing pressure, closing the guide channel.

[0021] In this embodiment, when the user's feet are in use, they are inserted into the housing 1 through the two sets of through holes on the protective cover 2 and step on the sliding plate 3. Under the action of gravity, the sliding plate 3 slides down along the sliding groove 11, compressing the telescopic rod 5 and the spring A6. At this time, the through hole tube A4, which is pressed by the foot, is subjected to downward pressure and remains in a downward extended state. Its lower end extends into the through hole tube B8 and pushes open the one-way sealing valve 9. The disinfectant is sprayed out through the through hole tube A4 under pressure to disinfect the contact area of ​​the foot. The through-hole tube A4, which is not pressed by the foot, retracts upward under the independent reset action, and the lower end does not contact the one-way sealing valve 9. The valve remains closed, and no disinfectant flows out. This achieves liquid discharge only in the area where the foot contacts the foot and automatic sealing of the non-contact area, adapting to different foot sizes and avoiding ineffective spraying and excessive splashing. After disinfection, the user removes their foot from the slide plate 3. The slide plate 3 returns to its original position under the action of the spring A6, the through-hole tube A4 disengages from the through-hole tube B8, and the one-way sealing valve 9 automatically closes, stopping the liquid discharge. Then, the user steps on the horizontal plate 16 on the top plate 14. The horizontal plate 16 is pressed downward, and the top rod 17 pushes the inclined block 18 to move downward along the guide structure, opening the hot air guide channel. The hot air sprayed from the nozzle 13 is guided upward by the inclined block 18 and blown directly onto the sole of the foot, quickly drying the residual disinfectant, preventing the sole of the shoe from becoming slippery, and improving walking safety. After the user leaves, the pressure on the horizontal plate 16 disappears, and the inclined block 18 resets upward under the action of the spring B19, re-sealing the flow channel. Hot air circulates in the closed space formed by the protective cover 2 and the shell 1, quickly drying the residual liquid inside, avoiding the accumulation of liquid and the growth of bacteria, reducing the risk of cross-infection, and keeping the device clean.
