Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical air purification and disinfection device. Background Technology

[0002] With the continuous advancement of medical technology, hospitals, clinics, and other medical facilities have increasingly stringent requirements for ambient air quality. In particular, pathogenic microorganisms, bacteria, and viruses in the air not only pose a threat to the health of patients but may also affect the working environment of medical staff. In order to effectively control these potential sources of air pollution, medical air purification and disinfection devices are needed. These devices integrate high-efficiency air filtration and disinfection technologies, which can effectively remove harmful substances such as particles, bacteria, and viruses from the air while ensuring fresh air, preventing the spread of diseases, reducing the risk of cross-infection, and enabling long-term stable operation in medical facilities to protect the health and safety of patients and medical staff.

[0003] Currently, there are various types of medical air purification and disinfection devices on the market. However, after long-term operation, the internal filters of these devices need to be replaced or cleaned regularly. Operators often need to perform complicated manual operations to disassemble and install them. The whole process is time-consuming and laborious, which increases the difficulty of operation and reduces maintenance efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a medical air purification and disinfection device.

[0005] This utility model is achieved by the following technical solution: a medical air purification and disinfection device, comprising a filter mechanism, an auxiliary mechanism and a body, wherein the filter mechanism is located on one side of the body and the auxiliary mechanism is located on the surface of the filter mechanism;

[0006] The filtering mechanism includes a protective shell, a limiting frame slidably connected to the surface of the protective shell, a filter screen fixedly connected to the inner wall of the limiting frame, a knob rotatably connected to the inner wall of the protective shell, a bidirectional threaded rod fixedly connected to the inner wall of the knob, a limiting plate threadedly connected to the surface of the bidirectional threaded rod, a limiting post slidably connected to the inner wall of the limiting plate, and a spring sleeved on the surface of the limiting post.

[0007] Through the above technical solution, the limiting column can enter the interior of the limiting frame, thereby effectively limiting it and ensuring that the internal filter screen is stably located inside the device.

[0008] As a further improvement to the above solution, the knob is located at the lower end of the limiting frame, and the surface of the bidirectional threaded rod is rotatably connected to the inner wall of the protective shell.

[0009] As a further improvement to the above solution, the limiting plate is located inside the protective shell, and the spring is located inside the limiting plate.

[0010] As a further improvement to the above solution, the auxiliary mechanism includes a baffle, a ventilation plate is fixedly connected to the inner wall of the protective shell, and an auxiliary groove is provided on the surface of the limiting frame.

[0011] Through the above technical solution, the baffle allows operators to easily restrict the position of the limiting frame during installation or disassembly, and ensures that no accidental sliding or loosening occurs during operation, thereby improving the safety of use.

[0012] As a further improvement to the above solution, the surface of the baffle is rotatably connected to the surface of the protective shell, the baffle is located at the upper end of the limiting frame, and the auxiliary groove is located at the upper end of the limiting frame.

[0013] As a further improvement to the above solution, the body includes a shell, a connecting plate is fixedly connected to one side of the shell, and a handle is fixedly connected to the upper end of the shell.

[0014] Through the above technical solution, operators can easily pick up the device using the handle, effectively adapting to the needs of different scenarios and improving the overall flexibility of use.

[0015] As a further improvement to the above solution, the connecting plate is located on the right side of the housing, the inner wall of the connecting plate is rotatably connected to the surface of the protective shell, and the baffle is snapped into the housing.

[0016] The above technical solution effectively ensures the stability of the protective shell by locking the baffle to the shell, preventing loosening due to improper operation.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model, through the setting of a filtration mechanism, allows the operator to push the limiting frame into the protective shell, causing it to contact the limiting post and generate a squeezing force. This causes the limiting post to retract inward and compress the spring. Once the limiting frame is fully inside the protective shell, the spring, through its restoring force, pushes the limiting post back, thus fixing the limiting frame and completing the installation of the filter screen. When the filter screen needs to be cleaned or replaced, the operator only needs to rotate the knob, which drives the bidirectional threaded rod to rotate, thereby moving the limiting plate outward. The movement of the limiting plate pushes the limiting post out of the protective shell, releasing the fixation of the limiting frame. The entire operation process is convenient and quick, effectively reducing the operator's working time and operational difficulty, improving work efficiency, and also facilitating daily maintenance, ensuring long-term stable operation.

[0019] This utility model, by setting up an auxiliary mechanism, allows the operator to effectively limit the top of the limiting frame by rotating the baffle, while simultaneously securing it to the housing. The ventilation plate guides outside air into the device, allowing the air to be effectively purified and disinfected as it passes through the filter. The auxiliary slot allows the operator to easily pull out the limiting frame, further improving operational convenience and maintenance efficiency. Attached Figure Description

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-7 The medical air purification and disinfection device of this embodiment includes a filter mechanism 1, an auxiliary mechanism 2 and a body 3. The filter mechanism 1 is located on one side of the body 3 and the auxiliary mechanism 2 is located on the surface of the filter mechanism 1.

[0032] The filter mechanism 1 includes a protective shell 11. A limiting frame 12 is slidably connected to the surface of the protective shell 11. A filter screen 13 is fixedly connected to the inner wall of the limiting frame 12. A knob 14 is rotatably connected to the inner wall of the protective shell 11. A bidirectional threaded rod 15 is fixedly connected to the inner wall of the knob 14. A limiting plate 16 is threadedly connected to the surface of the bidirectional threaded rod 15. A limiting post 17 is slidably connected to the inner wall of the limiting plate 16. A spring 18 is sleeved on the surface of the limiting post 17. The limiting post 17 can enter the interior of the limiting frame 12 to effectively limit it and ensure that the filter screen 13 inside the device is stably located inside.

[0033] The knob 14 is located at the lower end of the limiting frame 12, and the surface of the bidirectional threaded rod 15 is rotatably connected to the inner wall of the protective shell 11.

[0034] The limiting plate 16 is located inside the protective shell 11, and the spring 18 is located inside the limiting plate 16.

[0035] The auxiliary mechanism 2 includes a baffle 21, a ventilation plate 22 is fixedly connected to the inner wall of the protective shell 11, and an auxiliary groove 23 is opened on the surface of the limiting frame 12. The baffle 21 allows the operator to easily limit the position of the limiting frame 12 during installation or disassembly, and ensures that no accidental sliding or loosening occurs during operation, thereby improving the safety of use.

[0036] The surface of the baffle 21 is rotatably connected to the surface of the protective shell 11. The baffle 21 is located at the upper end of the limiting frame 12, and the auxiliary groove 23 is located at the upper end of the limiting frame 12.

[0037] The body 3 includes a housing 31, a connecting plate 32 is fixedly connected to one side of the housing 31, and a handle 33 is fixedly connected to the upper end of the housing 31. The operator can easily pick up the device using the handle 33, effectively adapting to the needs of different scenarios and improving the overall flexibility of use.

[0038] The connecting plate 32 is located on the right side of the housing 31. The inner wall of the connecting plate 32 is rotatably connected to the surface of the protective housing 11. The baffle 21 is snapped into the housing 31. The snapping of the baffle 21 into the housing 31 can effectively ensure the stability of the protective housing 11 and avoid loosening due to improper operation.

[0039] The implementation principle of a medical air purification and disinfection device in this embodiment is as follows: The operator pushes the limiting frame 12 into the protective shell 11. When the limiting frame 12 is pushed to move, its surface contacts and presses against the limiting post 17, causing the limiting post 17 to retract into the protective shell 11. At this time, the limiting post 17 presses against the spring 18, causing it to contract. When the limiting frame 12 is fully inside the protective shell 11, the spring 18 can push the limiting post 17 again, thus allowing the limiting post 17 to enter the limiting frame 11. Inside 2, the baffle 21 is rotated to block the top of the limiting frame 12, further ensuring the overall stability of the limiting frame 12. Then, the protective shell 11 is rotated, which causes the baffle 21 to rotate as well, thus engaging the baffle 21 with the shell 31, completing the installation of the filter screen 13. When the filter screen 13 needs to be cleaned or replaced, the operator pries the protective shell 11 outward to separate the baffle 21 from the shell 31, and then rotates it outward. The baffle 21 removes the restriction on the top of the limiting frame 12. By rotating the knob 14, the knob 14 drives the bidirectional threaded rod 15 to rotate, causing the limiting plates 16 on both sides to move outward continuously. The moving limiting plates 16 drive the limiting post 17 to move outward as well, until the limiting post 17 is completely inside the protective shell 11. At this point, the limiting post 17 no longer restricts the limiting frame 12, and the operator can easily remove the limiting frame 12 from inside the protective shell 11 to clean and replace the filter screen 13. The next time the limiting frame 12 is removed... Before installation, the operator needs to use the knob 14 to drive the limiting post 17 on the limiting plate 16 back to the initial position to ensure stable limiting. The operator can quickly and easily pull out the limiting frame 12 through the auxiliary slot 23. When the device is running, the ventilation plate 22 guides the outside air into the device, allowing it to come into contact with the filter screen 13 for filtration. The entire process of installing and removing the filter screen 13 is convenient and quick, further improving the operator's work efficiency. At the same time, the device is compact and can be lifted by the handle 33, making it easy to carry.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
