Technical Field
[0001] The utility model relates to the technical field of otolaryngology treatment, in particular to an ear canal aspirator for otolaryngology. Background Technique
[0002] Otitis externa or otitis media often causes an increase in external ear canal secretions. In severe cases, it may even block the external ear canal. If the secretions are not cleaned in time, it is not conducive to the normal recovery of the patient's disease, affects the patient's hearing, and is more likely to cause more serious cerumen impaction. Generally, when cleaning the external ear canal secretions, it usually needs to be completed by professional technicians in a dedicated treatment room. Patients need to frequently go to the hospital for medical treatment. When medical staff clean the secretions inside the patient's ear canal, they often use an ear canal aspirator. When the aspirator works, it is easy to adsorb dirt onto the motor and fan blades, which is likely to damage the motor. Therefore, some aspirators in the prior art are provided with filters to prevent dirt from entering the deep part of the device. However, such technologies have the problems of dirt fixation and filter blockage, which affect the air intake efficiency and the cleaning steps are cumbersome.
[0003] The prior art such as the publication number CN215839909U provides an ear canal aspirator for otolaryngology care, including: a box body, an exhaust fan, a suction head, a dirt filtering component, a motor, a driving wheel, a driven wheel, a filter belt, a cleaning brush, etc. When using this ear canal aspirator for otolaryngology care in the utility model, the dirt in the ear canal will also be sucked into the suction head by the negative pressure caused by the air flow. When the dirt enters the front end of the box body, it will be intercepted by the filter belt in the form of a filter mesh to prevent it from entering the deeper part of the box body. Since the filter belt will circulate with the driving wheel and the driven wheel, the dirt will adhere to the filter belt passing through the end of the suction head. The dirt will pass through the cleaning brush along with the movement of the filter belt. The top of the cleaning brush is in contact with the filter belt. Therefore, the dirt on the filter belt can be scraped off to prevent too much and too thick dirt from blocking the pores on the filter belt and affecting the air extraction efficiency.
[0004] When using this scheme, the dirt in the ear canal will also be sucked into the suction head by the negative pressure caused by the air flow. When the dirt enters the front end of the box body, it will be intercepted by the filter belt in the form of a filter mesh to prevent it from entering the deeper part of the box body and damaging the motor. The filter belt will circulate with the driving wheel and the driven wheel, and the dirt on the filter belt will pass through the cleaning brush along with the movement of the filter belt. The top of the cleaning brush is in contact with the filter belt. Therefore, the dirt on the filter belt can be scraped off. However, in actual use, during the long-term use of the filter belt, the tension may be insufficient, resulting in the obstruction of the movement of the filter belt and affecting the cleaning effect of the cleaning brush. Moreover, there may be some dirt in the pores of the filter belt that has not been removed by the cleaning brush. When the filter belt circulates to the inner side of the suction head at this time, it may cause the dirt to directly enter the deeper part of the box body and affect the operation of the motor. In view of this, we propose an ear canal aspirator for otolaryngology. Summary of the Invention
