Description

Seat part and smart stroller including the same {Seat part and mart stroller include the same}

The present invention relates to a seat portion and a smart stroller including the same, and more particularly, to a seat portion and a smart stroller having a structure capable of purifying air in a space in which an infant is seated.

Recently, fine dust generated due to climate change and industrialization has become a problem. As a person breathes, fine dust introduced into the body remains in the lungs, etc., and may adversely affect health.

Accordingly, dust-proof products such as masks are popularly sold to perform outdoor activities in a situation where fine dust is generated. However, there is a limit in that it is difficult to use dust-proof products such as masks for all age groups. This is due to the fact that you may feel stuffy when wearing a mask.

That is, in the case of adolescents or adults who can recognize the danger of fine dust, it is common to wear a mask even if it is stuffy. However, in the case of an infant who is difficult to recognize the risk, a lot of effort is required to maintain the state of wearing a mask.

Moreover, in the case of an infant who is difficult to walk on its own, it is common to ride on a stroller and the like to move. In this case, there is a difficulty in that the guardian drives the stroller in which the infant is boarded and at the same time checks the state of the infant wearing the mask.

Moreover, the concentration of fine dust can be changed in real time. That is, since the concentration of fine dust is high, the concentration of fine dust may decrease as time passes after a child wears a mask. Conversely, since the concentration of fine dust is not high, a child may go out without wearing a mask, but the concentration of fine dust may increase rapidly.

In this case, the guardian should change the child's mask wearing state according to the concentration of fine dust that changes in real time. Apart from decreasing the concentration of fine dust, if the concentration of fine dust increases rapidly, there is a risk that the infant may suffer from respiratory diseases if the mask is not worn at the appropriate time.

Korean Patent Document No. 10-2046253 discloses an air purifier for a stroller. Specifically, an air purifier provided in a canopy installed in a stroller to purify air flowing into the canopy is disclosed.

However, this type of air purifier for a stroller has a limitation in that it is provided integrally with the stroller. That is, in order to utilize the air purifier, there is a difficulty in that the entire stroller equipped with the air purifier must be purchased.

Moreover, the air purifier for a stroller suggested by the prior literature is not easy to separate from the stroller. Therefore, even when it is necessary to maintain only the air purifier, there is an inconvenience of maintaining the entire stroller.

Korean Patent Publication No. 10-2015-0142971 discloses a portable air purifier. Specifically, it discloses a mobile air purifier including a housing unit connected to the stroller and a filter unit installed in the housing unit to purify air.

However, this type of portable air purifier is premised on the premise that the cover part and the filter part for cleaning the air are integrally provided. That is, in order to provide the air purifier, the cover unit to which the air purifier is coupled must be provided together.

Furthermore, the above-mentioned prior documents have a limitation in that the provided air purifier purifies only air flowing in from a specific direction. That is, it does not suggest a method for purifying the air flowing in from various locations other than the location where the air purifier is provided.
