Abstract
本实用新型公开了一种感染科病房换气扇。它由排风扇和空气滤清器组成，排风扇的吸风口上设有密封盖，密封盖上设有空气滤清器连接口；空气滤清器的出气口与空气滤清器连接口相连接，空气滤清器内设有海绵杀菌过滤芯，空气滤清器的进气口上设有滤网，空气滤清器内还设有紫外线灯，紫外线灯上连接有电源线。本实用新型在原有感染科病房换气扇的基础上进行了改进，在空气滤清器内加装了紫外线灯，这样海绵杀菌过滤芯可以采用较低密度，以减少进气的阻力，提高其使用寿命，由外部经滤网进入空气滤清器的空气先由海绵杀菌过滤芯进行初步杀菌，然后经过紫外线灯照射后进行进一步杀菌，因此杀菌效果更好。
The utility model discloses a ventilating fan for an infection department ward. It consists of an exhaust fan and an air filter. The suction port of the exhaust fan is provided with a sealing cover, and the sealing cover is provided with an air filter connection port; the air outlet of the air filter is connected with the air filter connection port, and the air A sponge sterilizing filter core is arranged in the filter, a filter screen is arranged on the air inlet of the air filter, an ultraviolet lamp is also arranged in the air filter, and a power line is connected to the ultraviolet lamp. The utility model is improved on the basis of the original ventilation fan in the infection department ward, and an ultraviolet lamp is installed in the air filter, so that the sponge sterilizing filter element can adopt a lower density to reduce the resistance of air intake and improve its service life , The air entering the air filter from the outside through the filter screen is first sterilized by the sponge sterilizing filter element, and then further sterilized after being irradiated by ultraviolet light, so the bactericidal 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.
