To the further description of the present invention, the cap is threadedly coupled to the body.

To the further description of the present invention, the main body is connected to the suction ball through a snap-in seal.

Right the utility model discloses further description, two one sides of check valve are equipped with the valve gap, the check valve two-way pass the valve gap with exhaust hole in the main part compresses tightly.

Right the utility model discloses further description, the spiral cover still is equipped with the shield, the shield through detain the position with spiral cover zonulae occludens, the shield covers the suction nozzle.

It is right to the utility model discloses further description, the spiral cover the main part the material that the valve gap adopted is PP and injection moulding, the suction nozzle the check valve one the check valve two the material that the suction ball adopted is solid-state silica gel and injection moulding.

Compared with the prior art, the utility model has the advantages that:

1. the anti-backflow double-valve device is provided, the valves of the air inlet hole and the air outlet hole are all one-way valves, the backflow situation is avoided, and the operation is safe and convenient.

2. The suction nozzle adopts soft silica gel, can avoid hindering baby's nasal mucosa, and the shield has guaranteed that the product suction head is sanitary clean, is difficult for hiding dirty and holding dirt.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1, as shown in fig. 2 to 3:

the lower end surface of the main body 5 is tightly connected with the upper port of the suction ball 8 through a buckling position, so that the suction ball 8 is partially connected with the main body 5, the one-way valve II 7 is tightly sleeved on the exhaust port of the main body 5, the valve cover 6 is connected with the exhaust hole of the main body 5 through the buckling position, and at the moment, the assembly of the one-way exhaust valve of the anti-reflux device is completed. The one-way valve I4 is tightly sleeved on the lower end face of the air inlet hole of the spiral cover 3 to form a closed one-way air inlet channel, the spiral cover 3 is tightly screwed with the main body 5, the one-way air inlet valve for preventing air and nasal discharge from flowing reversely is assembled, the suction nozzle 2 is tightly sleeved at the upper end of the air inlet hole of the spiral cover 3, the upper soft part is suitable for being used by a baby, and finally the dust cover 1 is tightly connected with the spiral cover 3 through the buckling position, so that the sanitation and cleanness of a product suction head are guaranteed.

When the suction device is used, the suction ball 8 is squeezed to enable air to enter the main body 5, at the moment, the air is discharged through the exhaust hole of the main body 5 and the check valve II 7, the check valve I4 is tightly connected to the lower end face of the spiral cover 3, the air cannot leak from the air inlet hole of the spiral cover 3, the squeezed suction ball 8 is released, the air and the snivel pass through the suction nozzle 2 and the air inlet hole of the spiral cover 3, then enter the main body 5 through the check valve I4 and are stored in the space of the main body 5, and the smooth and easy-to-operate snivel suction process is completed.

When the dust cap is not used, the dust cap 1 is tightly connected with the screw cap 3 through the buckling position. The anti-reflux device can prevent the air of the nasal discharge from flowing back into the nostril of the infant, and is simpler and quicker to operate, convenient and sanitary.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
