Description

Technical Field

[0001] The utility model relates to the technical field of protective doors, in particular to an antibacterial door. Background Art

[0002] In the current medical environment, hospital doors are primarily made of wood and steel. While these two materials meet basic hospital needs to a certain extent, they also face numerous challenges that require urgent resolution. First, medical doors, as areas frequently touched by patients, harbor high rates of bacterial survival and growth. This increases the risk of multiple infections, posing a significant threat to patients' health, particularly in hospitals, where cross-infection is a common occurrence.

[0003] Secondly, with the growing problem of antibiotic overuse, infections caused by drug-resistant bacteria are likely to spread more widely in the future. To effectively curb their spread, hospitals need to regularly disinfect their environments. However, while current chemical disinfection methods are effective to a certain extent, they inevitably lead to secondary environmental pollution. Furthermore, chemical disinfection methods cannot guarantee stable and efficient sterilization around the clock, leaving gaps in spraying frequency for bacterial infection and the risk of disease transmission. This not only increases hospital operating costs but also poses a potential threat to the health of patients and medical staff.

[0004] Therefore, there is an urgent need to find an effective and continuous way to kill common infectious bacteria on their own, so as to form a seamless supplement to traditional sterilization methods. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide an antibacterial door to improve the sterilization effect of existing hospitals and reduce the spread of pathogens.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An antibacterial door comprises a door leaf, the door leaf comprising a first substrate layer, a second substrate layer, a filling layer, and an antibacterial layer, the filling layer being provided between the first substrate layer and the second substrate layer, and the antibacterial layer being provided on surfaces of the first substrate layer and the second substrate layer;

[0008] The top end, the bottom end and both sides of the door leaf are provided with sealing structures, so that the door leaf and the door frame form a seal when in a closed state.

[0009] The aforementioned technical approach effectively achieves real-time sterilization and antibacterial effects by providing an antibacterial layer on the surface of the door leaf. This effectively blocks bacterial transmission even between spraying intervals. Using this antibacterial door as a hospital door effectively enhances the hospital's overall sterilization effectiveness. Furthermore, sealing structures are provided at the top, bottom, and both sides of the door leaf, creating an effective, all-around seal between the door leaf and the door frame when closed, reducing the spread of germs.

[0010] Preferably, the sealing structure at the bottom end of the door leaf comprises a shell, a sweeping sealing strip installed in the shell, and a spring pin installed on the shell;

[0011] The sweeping sealing strip is connected to the spring pin, so that when the door leaf is opened, the spring pin is stretched, driving the sweeping sealing strip to move upward; when the door leaf is closed, the spring pin abuts against the door frame, the spring pin is compressed, driving the sweeping sealing strip to move downward.

[0012] By cleverly setting a shell, a sweeping sealing strip and a spring pin installed in the shell at the bottom end of the door leaf, when the door leaf is opened, the spring pin is stretched, driving the sweeping sealing strip to move upward; when the door leaf is closed, the spring pin abuts against the door frame, the spring pin is compressed, driving the sweeping sealing strip to move downward, which not only achieves the smooth opening of the door leaf and avoids interference, but also ensures the sealing performance when the door leaf is closed, greatly reduces the spread rate of pathogens, improves the sound insulation effect, and thus better protects the privacy of patients.

[0013] Preferably, the shell is made of aluminum alloy.

[0014] Preferably, the top and both sides of the door frame are of stepped structure at the locations where they match with the door leaf.

[0015] By setting the top and both side ends of the door frame into a stepped structure, the contact area between the door frame and the door leaf is effectively increased, further improving the sealing performance, thereby further reducing the transmission rate of germs.

[0016] Preferably, a first sealing structure is provided on the first step of the door frame, and a second sealing structure is provided on the door leaf at a position corresponding to the second step of the door frame, so that the door leaf and the door frame form a double seal in a closed state.

[0017] Preferably, the first sealing structure is a sealing strip, and the cross section of the first sealing structure along the width direction is a D-shaped structure.

[0018] Preferably, the second sealing structure is a sealing strip, and the cross-section of the second sealing structure along the width direction is rectangular.

[0019] By setting the first sealing structure to a D-shaped structure and the second sealing structure to a rectangular structure, the sealing performance is ensured and the problem of difficulty in opening the door leaf due to excessive contact area is avoided.

[0020] Preferably, the first substrate layer and the second substrate layer are made of cold-rolled steel plates.

[0021] By making the first substrate layer and the second substrate layer from cold-rolled steel plates, the strength of the antibacterial door is ensured.

[0022] Preferably, the thickness of the first substrate layer and the second substrate layer is between 0.6 and 0.8 mm.

[0023] Preferably, the filling layer is made of environmentally friendly honeycomb paper core.

[0024] By using environmentally friendly honeycomb paper core as the filling layer, the cost of the antibacterial door is effectively reduced and the sound insulation effect of the antibacterial door is improved.

[0025] Preferably, the antibacterial layer is formed by electrostatic spraying of antibacterial powder;

[0026] The antibacterial powder is selected from at least one of a silver-based antibacterial agent, a zinc-based antibacterial agent, a copper-based antibacterial agent and an organic antibacterial agent.

[0027] The antibacterial powder is directly sprayed on the surfaces of the first substrate layer and the second substrate layer by adopting an electrostatic spraying process, which has the advantages of simple operation and good adhesion performance.

[0028] Preferably, the thickness of the antibacterial layer is between 60 and 100 μm.

[0029] Preferably, a handle is provided on the door leaf.

[0030] Beneficial effects of the utility model:

[0041] like Figures 1 to 6 As shown, an antibacterial door includes a door leaf 1, which includes a first substrate layer 11, a second substrate layer 12, a filling layer 13 and an antibacterial layer 14. The filling layer 13 is provided between the first substrate layer 11 and the second substrate layer 12, and the antibacterial layer 14 is provided on the surfaces of the first substrate layer 11 and the second substrate layer 12;

[0042] Sealing structures are provided at the top, bottom and both sides of the door leaf 1 so that the door leaf 1 and the door frame 2 form a seal when closed.

[0043] By applying an antimicrobial coating to the door leaf surface, the dual effects of real-time sterilization and antibacterial protection are successfully achieved, effectively blocking the path of bacterial transmission even during the intervals between disinfectant spraying. The application of this antimicrobial door in hospital environments significantly improves the hospital's overall sterilization efficiency. Furthermore, carefully designed sealing structures at the top, bottom, and sides of the door leaf ensure a comprehensive, highly effective seal between the door leaf and the door frame when closed, further reducing the risk of pathogen transmission.

[0044] In some embodiments, the sealing structure at the bottom end of the door leaf 1 includes a housing 3, a sweeping sealing strip 4 installed in the housing 3, and a spring pin 5 installed on the housing 3;

[0045] The sweeping sealing strip 4 is connected to the spring pin 5, so that when the door leaf 1 is opened, the spring pin 5 is stretched, driving the sweeping sealing strip 4 to move upward; when the door leaf 1 is closed, the spring pin 5 abuts against the door frame 2, the spring pin 5 is compressed, driving the sweeping sealing strip 4 to move downward.

[0046] By cleverly arranging a shell, a sweeping type sealing strip and a spring pin installed in the shell at the bottom end of the door leaf, when the door leaf is opened, the spring pin stretches, driving the sweeping type sealing strip to move upward, so that the sweeping type sealing strip leaves the ground 9, thereby achieving smooth opening of the door leaf and avoiding interference; when the door leaf is closed, the spring pin abuts against the door frame, the spring pin compresses, driving the sweeping type sealing strip to move downward, so that the sweeping type sealing strip abuts against the ground 9, ensuring the sealing performance when the door leaf is closed, greatly reducing the spread rate of pathogens, and improving the sound insulation effect, thereby better protecting the patient's privacy.

[0047] Exemplarily, the shell 3 is made of aluminum alloy.

[0048] In some embodiments, in order to increase the contact area between the door frame and the door leaf, to further improve the sealing performance and thus further reduce the transmission rate of germs, the top and both sides of the door frame 2 that cooperate with the door leaf 1 are provided with a stepped structure.

[0049] In some embodiments, a first sealing structure 6 is provided on the first step of the door frame 2, and a second sealing structure 7 is provided on the door leaf 1 at a position corresponding to the second step of the door frame 2, so that the door leaf 1 and the door frame 2 form a double seal when closed.

[0051] In some embodiments, the second sealing structure 7 is a sealing strip, and the cross-section of the second sealing structure 7 along the width direction is rectangular.

[0052] By setting the first sealing structure to a D-shaped structure and the second sealing structure to a rectangular structure, the sealing performance is ensured and the problem of difficulty in opening the door leaf due to excessive contact area is avoided.

[0053] For example, in order to ensure the strength of the antibacterial door, the first substrate layer 11 and the second substrate layer 12 are prepared using cold-rolled steel sheets.

[0054] In some embodiments, the thickness of the first substrate layer 11 and the second substrate layer 12 is between 0.6 mm and 0.8 mm.

[0055] In some embodiments, in order to reduce the cost of the antibacterial door and improve the sound insulation effect of the antibacterial door, the filling layer 13 is made of an environmentally friendly honeycomb paper core.

[0056] In some embodiments, in order to simplify the operation and ensure the adhesion performance of the antibacterial layer, the antibacterial layer 14 is formed by spraying antibacterial powder;

[0057] The antibacterial powder is selected from at least one of silver-based antibacterial agents, zinc-based antibacterial agents, copper-based antibacterial agents and organic antibacterial agents.

[0058] In some embodiments, the thickness of the antibacterial layer 14 is between 60 μm and 100 μm.

[0059] In some embodiments, a handle 5 is provided on the door leaf 1 .

[0060] In summary, the antimicrobial door of this utility model achieves the dual effects of real-time sterilization and continuous antibacterial protection during use by carefully applying a layer of special antimicrobial material to the door surface.
