The sound of the whistle can remind the operator that the pressure regulating valve 2 has worked, indicating that the suction pressure in the suction pipe 14 or 14' is too large or blocked, and the suction head 52 of the suction device 5 or the suction pipe must be checked. Whether it touches the nasal mucosa or oral mucosa and causes obstruction or other obstructions in the suction manifold 12. In this way, when the user's nasal mucus or phlegm is sucked, if the nasal mucosa or oral mucosa is accidentally touched, it is unknown. When the inhalation action is continued, the setting of the pressure regulating valve 2 of the new type can prevent injury to the nasal mucosa or oral mucosa of the user, so it is extremely safe in use; when the inhalation manifold 12 is blocked When it is released (for example, the suction head 52 or the suction catheter does not contact the nasal mucosa or oral mucosa) or when the pressure in the suction pipes 14 and 14' is reduced, the spring 24 is elastically restored, and the plug 25 is pushed back. until the valve is blocked The position of the air hole 231 of the body 23 can successfully perform the suction action from the suction manifold 12 again, so that the best pressure relief and whistle warning effect can be achieved.
