Description

Technical Field

[0001] The utility model belongs to the technical field of disinfection equipment, and in particular relates to a small air purification and disinfection device for a ward. Background Art

[0002] There are many types of disinfection equipment in hospitals, which can be roughly divided into instrument disinfection and environmental disinfection. For environmental disinfection, disinfectant is usually sprayed manually. In addition, there are also some disinfection robots or disinfection devices. For example, an ultraviolet lamp disinfection device is placed in the ward and disinfected after being turned on for a period of time. In the ward, the air quality will affect the health of the surrounding people. The air purification and disinfection devices currently used in wards have relatively simple functions, such as ultraviolet disinfection, ozone disinfection, air filtration, etc. In addition, this type of equipment is large in size, and generally has a movable roller at the bottom of the equipment, and can only be purified and disinfected periodically, and cannot work continuously. Therefore, a small, sustainable air purification and disinfection device is urgently needed for use in wards. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a small air purification and disinfection device for a ward, aiming to solve the above technical problems.

[0004] The utility model adopts the following technical solutions:

[0005] The small air purification and disinfection device for the ward includes a base and an intermediate shell installed on the top of the base. The outer wall of the base is provided with an air inlet hole. The top of the intermediate shell is provided with an air outlet hood. An annular sealing plate and an annular wind net are arranged above and below the intermediate shell. An annular filter element is arranged between the annular sealing plate and the annular wind net. An ultraviolet lamp is also arranged at the center of the annular filter element. A small fan is also arranged above the center of the annular filter element in the intermediate shell, and there is an upper filter element above the small fan.

[0006] Furthermore, a cylindrical table is provided in the base, the bottom of the ultraviolet lamp is installed in the cylindrical table, the upper part is located at the center of the annular filter element, and the top of the cylindrical table is located at the inner circle of the annular air network.

[0007] Furthermore, the center position of the annular filter element has an upper conduit pointing upwards and a lower conduit pointing downwards, wherein the lower conduit is matched and inserted into the cylindrical platform, and the upper conduit is inserted into the center of the annular sealing plate.

[0008] Furthermore, the top of the air outlet cover is an air outlet, and the inner wall is provided with a circle of pressure ring. The air outlet cover is screwed into the top of the intermediate shell, and the pressure ring presses the upper filter element.

[0009] The beneficial effects of the utility model are as follows: the purification and disinfection device can be placed on the bedside table of the ward. When the small fan is working, negative pressure is formed in the annular filter element. The air in the ward enters from the air inlet hole on the outer periphery of the base, and then passes through the annular wind net, the annular filter element, and the ultraviolet lamp. The purified and disinfected air then passes through the upper filter element and is finally discharged from the top of the air outlet hood. The device can work continuously, occupies a small area, and can realize two purification and filtration and one ultraviolet disinfection, which can form a better purification and disinfection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a cross-sectional view of a small air purification and disinfection device provided by an embodiment of the present utility model;

[0011] Figure 2 It is a partial enlarged view of the small air purification and disinfection device provided by an embodiment of the utility model. DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0013] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0014] like Figure 1-2 As shown, the small air purification and disinfection device for the ward provided in this embodiment includes a base 1 and an intermediate shell 2 installed on the top of the base 1, the outer wall of the base 1 is provided with an air inlet 11, and the top of the intermediate shell 2 is installed with an air outlet hood 3, and an annular sealing plate 4 and an annular wind net 5 are arranged above and below the intermediate shell 2, wherein an annular filter element 6 is arranged between the annular sealing plate 4 and the annular wind net 5, and an ultraviolet lamp 7 is also arranged at the center of the annular filter element 6, and a small fan 8 is also arranged above the center of the annular filter element 6 in the intermediate shell 2, and an upper filter element 9 is also arranged above the small fan 8.

[0015] In this structure, the annular filter element is a primary filter element, and the upper filter element is a medium-efficiency filter element (of course, high-efficiency filter elements can also be used). The filter elements are mainly used to filter dust, microorganisms and harmful substances in the air, ensuring the cleanliness and safety of the air in the ward. The primary filter element is the first stage of purification, mainly used to filter dust particles with a size of 5μm or more and various foreign matter. The medium-efficiency filter element improves purification efficiency.

[0016] In this embodiment, the annular filter element is located below an annular air mesh, which does not affect the upward flow of air into the annular filter element. The annular filter element is located above an annular sealing plate. The annular filter element is hollow inside and can accommodate a small ultraviolet lamp. When the small fan is turned on, negative pressure is generated at the position of the ultraviolet lamp. The air in the ward enters through the air inlet hole on the outer periphery of the base, and then passes through the annular air mesh and annular filter element for primary filtration and disinfection by the ultraviolet lamp. The purified and disinfected air is then filtered twice by the upper filter element and finally discharged from the top of the air outlet hood, ultimately achieving efficient purification and disinfection of the ward air.

[0017] As a specific structure, such as Figure 2 As shown, there is also a cylindrical table 12 in the base 1, and the bottom of the ultraviolet lamp 7 is installed in the cylindrical table 12, and the upper part is located at the center of the annular filter element 6. The top of the cylindrical table 12 is located at the inner circle of the annular wind net 5. The center position of the annular filter element 6 has an upper duct 61 upward and a lower duct 62 downward, wherein the lower duct 62 is matched and inserted into the cylindrical table, and the upper duct 61 is inserted into the center of the annular sealing plate. The annular filter element is made of cotton material and has a certain hardness. The annular filter element has upper and lower ducts and can be stably installed. In this structure, the base and the intermediate shell are also detachable and can be replaced after disassembly.

[0018] Finally, if Figure 1 As shown, the top of the air hood 3 is an air outlet 31, and the inner wall has a circle of pressure ring 32. The air hood 3 is screwed into the top of the intermediate housing 2, and the pressure ring 32 presses the upper filter element 9. The air hood can be disassembled by tightening and loosening. After removing the air hood, the upper filter element can be directly replaced.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
