Abstract
The utility model discloses an air exchange fan for a ward of an infectious department, which consists of an exhaust fan and an air filter, wherein an exhaust inlet of the exhaust fan is provided with a sealing cover; the sealing cover is provided with an air filter connection port; an air outlet of the air filter is connected with the air filter connection port; a sponge sterilizing filter core is arranged in the air filter; an air inlet of the air filter is provided with a filter screen; an ultraviolet lamp is also arranged in the air filter; and the ultraviolet lamp is connected with a power wire. The air exchange fan carries out improvement based on the original air exchange fan for the ward of the infectious department and additionally arranges the ultraviolet lamp in the air filter, so that the sponge sterilizing filter core can adopt lower density to reduce air inlet resistance and prolong the service life of the air exchange fan. Air entering the air filter from the outside by the filter screen is primarily sterilized by the sponge sterilizing filter core and then is further sterilized after being irradiated by the ultraviolet lamp, and thus, the sterilizing effect is better.
Description
Technical field
The utility model relates to the ventilation fan technical field, relates in particular to the clinical ventilation fan of a kind of Infectious Disease.
Background technique
The air germ content in hospital infection section ward is more, as untimely processing, environment around will polluting, and patient and staff exist together one relatively the sealing environment in, be very easy to cause the cross infection of disease through breathing, in the past, the sterilization treatment work in hospital infection section ward was the same with public ward, was not specifically designed to the facility of air-treatment in Infectious Disease's Ward.The someone has proposed design proposal preferably for this reason, disclosed by utility model patent Liu Hong, Wang Jingwei design, that the patent No. is 200720140690.6, name is called Infectious Disease's ward ventilation fan as State Intellectual Property Office on April 16th, 2008, it is made up of ventilating fan and air-strainer, the air sucking mouth of ventilating fan is provided with sealing cover, and sealing cover is provided with the air-strainer connection mouth; The air outlet of air-strainer is that wire connection cooperates with the air-strainer connection mouth, is provided with sponge disinfection filtering core in the air-strainer, and the suction port of air-strainer is provided with filter screen.Its overall structure is simpler, and dismounting, easy for installation is carried out sterilizing treatment when discharging indoor air.Its shortcoming be the density of sponge disinfection filtering core when too high the resistance of ventilation fan bigger, damage motor easily, and the too low bactericidal effect that can cause of the density of sponge disinfection filtering core is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of not fragile, long service life, Infectious Disease's ward ventilation fan that bactericidal effect is good.
The technological scheme that the utility model is adopted for achieving the above object is:
A kind of Infectious Disease ward ventilation fan is made up of ventilating fan and air-strainer, and the air sucking mouth of ventilating fan is provided with sealing cover, and sealing cover is provided with the air-strainer connection mouth; The air outlet of air-strainer is connected with the air-strainer connection mouth, be provided with sponge disinfection filtering core in the air-strainer, the suction port of air-strainer is provided with filter screen, it is characterized in that: also be provided with ultraviolet lamp in the described air-strainer, be connected with power line on the ultraviolet lamp.
The utility model improves on the basis of original Infectious Disease ward ventilation fan, in air-strainer, installed ultraviolet lamp additional, sponge disinfection filtering core can adopt than low density like this, to reduce the resistance of air inlet, improve its working life, earlier carry out preliminary sterilization by the outside through the air that filter screen enters air-strainer, shine the further sterilization of laggard row through ultraviolet lamp then, so bactericidal effect is better by sponge disinfection filtering core.
