a timer is arranged outside the drying adjusting box (4), one end of the timer is connected with a power supply, the other end of the timer is connected with a suction fan (7), an air channel adjusting valve is arranged at the joint of the drying adjusting box (4) and the sterile air inlet pipe (2), and the air channel adjusting valve is communicated with the sterile air inlet pipe (2) so as to adjust the suction air volume; the timer adopts a knob timing mode; through the timer control suction fan (7) and wind channel governing valve work, come control drying process, include:
dividing the drying process into a pre-starting drying stage, a powerful drying stage and a pre-finishing drying stage, and setting corresponding working time through a timer according to the characteristics of the drying process in different stages;
in the pre-starting drying stage, the air duct regulating valve keeps a half-open state, and the suction fan (7) works according to first working time set by the timer; in the powerful drying stage, the air duct adjusting valve is kept in a fully-open state, and the suction fan (7) works according to the second working time set by the timer; in the pre-finishing drying stage, the air duct adjusting valve keeps a half-open state, and the suction fan (7) works according to the third working time set by the timer.
9. The drying apparatus for sterilization of medical instruments according to claim 8, wherein: the front of the drying cabinet body (1) is provided with a cabinet door (8) through a hinge, and an ultraviolet lamp panel (801) is embedded on the surface of one side of the cabinet door (8) close to the support rod (5).
10. A drying apparatus for sterilization of medical instruments according to claim 9, characterized in that the drying apparatus is operated as follows:
s1, before the drying equipment is used for providing sterilization treatment for medical instruments, the screen plate (503) is pushed into the accommodating groove (502) to enable the drying rack (501) to form a ventilated supporting structure, the sterilized and cleaned medical instruments are placed on the surface of a bracket formed by the combination of the drying rack (501) and the screen plate (503), and then the cabinet door (8) is closed to facilitate subsequent drying treatment;
s2, detecting the temperature and humidity conditions in the air at the back of the drying cabinet body (1) according to the temperature and humidity sensor (206), an electronic valve (205) and a suction fan (7) on the surface of the second air inlet pipe (204) are opened under the condition of higher air humidity, when the air at the back of the drying cabinet body (1) enters the drying adjusting box (4) through the sterile air inlet pipe (2), on the premise that the power of the suction fan (7) is constant, so that the suction wind speed is constant, the movement distance of the air entering the drying and adjusting box (4) through the second air inlet pipe (204) is longer, so that the time for sterilizing the air in the sterile air inlet pipe (2) is longer, relatively sufficient sterilization can be obtained, further reducing the content of harmful microbe in the humid air, so that the air sucked from the drying and adjusting box (4) is in a sterile state;
s3, after air enters the drying adjusting box (4) through the sterile air inlet pipe (2), the air is subjected to heating treatment through the heating frame (402) and is discharged to the inside of the drying cabinet body (1) in a one-way mode through the adjusting pipe (401) for heat drying treatment, according to the residual water quantity on the surface of an object on a bracket and the requirement of drying time, the air outlet force inside the drying adjusting box (4) is adjusted through the adjusting pipe (401) so as to accelerate the drying operation, the miniature electric telescopic rod (405) is started, then the conical air outlet pipe (403) is driven to move upwards and the rubber sleeve (407) is attached to the inner wall of the adjusting pipe (401), further the air inside the drying adjusting box (4) is changed from the original outlet discharge of the adjusting pipe (401) into the outlet discharge through the conical air outlet pipe (403), and under the conditions of unchanged air inlet amount and reduced air outlet area through the adjustment of the outlet area, hot air discharged by the conical air outlet pipe (403) is subjected to accelerated treatment, so that the blowing-off and volatilization of water drops on the surface of the medical instrument can be accelerated during drying, and the drying speed is improved;
s4, in the drying process, starting the electric telescopic sleeve rod (901) to reciprocate, further driving the detection ring (9) to reciprocate up and down along the surface of the sterile air inlet pipe (2), further utilizing the ultrasonic flaw detection probe (902) to detect cracks on the surface of the sterile air inlet pipe (2), thereby avoiding that the air transferred into the drying cabinet body (1) has harmful microbe bacteria due to the fact that the cracks exist, the external air enters the sterile air inlet pipe (2) through the cracks to cause that the air cannot be killed for sufficient time, further reducing the possibility of secondary pollution of medical instruments in the drying process, in addition, the air in the drying cabinet body (1) is conveyed to the rear part of the drying cabinet body (1) through the conveying pipe (6) to heat the air near the sterile air inlet pipe (2), further heating the harmful microbe bacteria in the air, the activity is reduced, so that death can be accelerated when the air enters the sterile air inlet pipe (2) subsequently, and the sterility of air suction inside the sterile air inlet pipe (2) is ensured;
s5, after the drying is finished, the cabinet door (8) is opened, the receiving utensil is supported below the bracket, and then the screen plate (503) is taken out from the inside of the receiving groove (502) by the convex strip (504), thereby realizing batch collection and reducing the labor load of the subsequent collecting and sorting operation.
