Description

A stroller with air purification function

technical field

The invention relates to the field of baby products, in particular to a baby carriage with an air purification function.

Background technique

Air quality issues are increasingly arousing widespread concern. Especially for infants, they have a fast metabolism and breathe more than adults, so poor air quality is more likely to cause greater harm to them. At present, most of the strollers on the market do not have the function of air purification, so they cannot provide effective protection for the baby to go out.

The Chinese invention patent application with the publication number CN104627228A discloses a baby stroller that can purify the air, and can pass the air to the baby rest room through the trachea after being purified. Feel to control the switch of the purification equipment, and the air outlet of the fan is facing the baby's head, which is likely to adversely affect the baby's sleep.

The Chinese utility model patent application with the authorization number CN207565664U authorizes an air purification device for a baby carriage. This design does not have an exhaust device, so that the air in the baby rest room cannot be circulated, and the waste gas in the baby rest room cannot be effectively discharged.

SUMMARY OF THE INVENTION

In view of the deficiencies in the prior art, the present invention provides a baby carriage with an air purification function.

In order to achieve the above purpose, the present invention provides the following technical solutions: a baby carriage with an air purification function, which includes a baby carriage body, an airtight outer cover, an air quality detection device, an air intake purification device, an air exhaust device, a device switch and a device switch. The power supply, the air quality detection device detects the air quality inside the stroller in real time. If the air quality is poor, the buzzer will give an alarm. At this time, the user needs to cover the airtight cover and turn on the device switch, and the air intake purification device will inhale the outside. The air is filtered, rectified and diverted into the baby rest compartment, and the exhaust gas in the baby rest compartment is exhausted by the exhaust device, so as to maintain the air circulation inside the stroller.
