Description

[Technical field]

[0001] The present invention relates to a blower fan to be installed in a seat cover and a seat cover equipped with the blower fan. [Background technology]

[0002] When a seat or seat cover is used for a long time or when the surrounding temperature is high, such as in summer, heat and moisture tend to build up in the areas where the seat surface comes into contact with the user. In particular, if the user is an infant or small child, the build-up of heat can cause symptoms such as heatstroke.

[0003] For this reason, various strollers and seat covers have been proposed that are equipped with ventilation fans in the seat or seat cover to blow air onto the surface of the seat or seat cover, thereby expelling heat and moisture trapped between the user's body and the seat or seat cover.

[0004] For example, Patent Document 1 describes a stroller blower device that is positioned on the rear side of the backrest of a stroller, blows outside air in the direction of the backrest, and can be attached to the rear side of the backrest using multiple mounting members provided on the main body case.

[0005] For example, Patent Document 2 describes an infant cover that includes a cloth body that covers an infant in an infant carrier, a fan that supplies outside air into the cloth body, and a fastener that removably fixes the cloth body to the infant carrier.

[0058] In this way, the cover portion 2 can be attached to the blower fan body 1.

[0059] <Effects> According to this embodiment, by providing a plurality of through holes 21 in the raised surface S1, it becomes possible to draw air from a plurality of directions, and therefore the air can be drawn in more efficiently. In addition, it is possible to prevent an object from covering the air intake port 112.

[0060] Furthermore, because the cover part 2 is formed in a dome shape, it is possible to make the volume of the cover part 2 compact while easily distributing external loads and pressures throughout the cover part 2, thereby preventing damage to the cover part 2.

[0061] In addition, since the blower fan X further includes an attachment part 3 for attaching the cover part 2 to the blower fan body 1 in a freely detachable manner, it becomes possible to attach and detach the cover part 2 from the housing 11 depending on the damage state of the cover part 2 and the location where the blower fan X is installed.

[0062] Furthermore, since the exhaust port 113 is provided with a guard portion 112g, even when the cover portion 2 is removed from the housing 11, the blower fan X can be used safely.

[0063] In addition, the mounting portion 3 has an upright portion 31 and a groove portion 32, a notch 311 is provided at the end 31a of the upright portion 31, and a protrusion 321 that engages with the notch 311 is provided at the groove portion 32, thereby preventing the cover portion 2 from coming off the housing 11.

[0064] In addition, since the fan section 111 is a centrifugal fan and the exhaust port 113 is provided on the front side of the housing 11, it is possible to blow air stably and efficiently without depending on the wind conditions around the blower fan X.

[0065] In addition, the partition portion 12 extends from the side of the internal space of the blower fan body 1 in the opposite direction to the rotation direction of the fan portion 111 when viewed in a plane, thereby preventing the air blown by the fan portion 111 from being sucked back into the internal space of the housing 11.

[0066] <Example of change> The shapes and dimensions of the components shown in the above-described embodiment are merely examples and can be modified in various ways based on design requirements, etc.

[0067] For example, a plurality of cover parts 2 with different heights of the top surface S2 may be provided. With this configuration, it becomes possible to replace the cover portion 2 depending on the surrounding environment in which the blower fan X is installed.

[0068] For example, the standing portion 31 may be provided on the cover portion 2, and the groove portion 32 may be provided on the blower fan body 1.

[0069] For example, the protrusion 321 may be configured to be able to engage with the auxiliary hole h. In this way, the cover portion 2 can be fixed to the housing 11 more firmly.

[0070] For example, a battery for supplying electricity to the control unit 131 and the fan unit 111 may be provided inside the blower fan body 1. By doing so, the blower fan X can be made more compact. [Explanation of symbols]
