Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a ventilated cushion which can be used in combination with a baby crib, a baby carriage, a seat, a mattress and the like. Background Art

[0002] In order to sit more comfortably, a cushion is sometimes placed on products such as cribs, strollers, seats, mattresses, etc. Since sitting for a long time (or sleeping for a long time) can easily cause heat even with a cushion, especially in hot and humid weather, it will make people feel very uncomfortable. For this reason, people have invented cushions with ventilation functions, such as the children's ventilated cushion disclosed in patent CN201620710575.7, which has ventilation and cooling effects and can improve the comfort of children when riding in strollers or car safety seats. However, if the cushion is thicker in order to accommodate a fan, it needs to be thicker, otherwise the fan cannot be installed and its ventilation function cannot be achieved. But if the thickness is increased, the entire cushion will be too heavy, causing inconvenience to use. In addition, the fan of the existing ventilated cushion only has an ordinary protective structure, and when used in the field of infant and children's products, because the fingers of infants and children are thin, there is a safety hazard that the fingers may be inserted into the fan and cause personal injury accidents. If the mesh part of the protective structure is set densely, it will affect the air outlet effect. Utility Model Content

A fan installation area 11 is arranged near the front end (or lower end) of the flexible cushion body 1. The fan 2 is installed in the fan installation area 11 in an embedded manner. The air outlet of the fan 2 is exposed on the surface of the cushion body 1 so as to blow air upwards. The air inlet 6 of the fan 2 is exposed on the bottom surface of the cushion body 1. The fan 2 comprises an upper shell 3, a lower shell 4 and a cover 5. The blades of the fan 2 (not shown) are installed in the blade grooves 41 of the lower shell 4. The upper shell 3 covers the lower shell 4 to cover the fan blades, and the air inlet 6 is set on the lower shell 4; the upper shell 3 is provided with a meshed fan blade cover 31 at the position aligned with the fan blades, and the surface cover 5 is provided with a protective cover 51 at the position aligned with the fan blade cover 31. The surface cover 5 covers the upper shell 3, and the protective cover 51 covers the fan blade cover 31, so that there is a safety gap between the fan blade cover 31 and the protective cover 51, so that even if a finger is inserted into the protective cover 51, it will not touch the fan blade due to the long distance, thereby preventing accidents. The protective cover 51 is exposed on the surface of the cushion body 1, and the wind blown by the fan 2 passes through the protective cover 51 and blows upward.

[0020] An annular vertical wind guide cover 32 is arranged around the fan blade cover 31, and the wind guide cover 32 is separated between the upper shell 3 and the protective cover 51 to form an air outlet channel from the fan blade to the protective cover 51. In this way, it can prevent the wind from leaking out from between the upper shell 3 and the cover 5 to the surroundings, thereby increasing the air volume.

[0021] The air inlet 6 is arranged on the side wall of the lower shell 4 and communicates with the blade slot 41. A portion of the lower shell 4 is exposed below the bottom surface of the cushion body 1 so that the fan 2 forms a side air inlet structure. In this way, there is no need to set a large space under the fan 2 for air inlet, making it more convenient to use.

[0022] An opening (not shown) is provided on the side of the cushion body 1 through a zipper (not shown), and the entire fan 2 is installed in the cushion body 1 after the opening is opened through the zipper, making it very convenient to install and take out the fan 2.

[0023] A zipper installation position 12 extending toward both sides is provided on the cushion body 1 near the fan installation area 11 , and a zipper (not shown) is provided in the zipper installation position 12 , and the entire cushion can be conveniently installed on the stroller through the zippers on both sides.

[0024] An operation panel 33 is arranged on the surface of the upper shell 3, and a mounting hole 52 is arranged in the surface cover 5 at a position corresponding to the operation panel 33. The operation panel 33 is embedded in the mounting hole 52 to be exposed on the surface of the pad body 1 for easy operation and control.

[0025] A buckle 34 is provided at the edge of the upper shell 3, and a buckle hole 42 is provided at the edge of the lower shell 4. The upper shell 3 and the lower shell 4 are combined and fixed by buckling the buckle 34 and the buckle hole 42, making assembly and disassembly very convenient. The entire fan 2 can be fixed to the pad body 1 using screws or Velcro.

[0026] The fan 2 is provided with a lithium battery and a USB interface (not shown), and the fan can be driven by the lithium battery or directly connected to a charger using a data cable. The fan 2 includes two fan blades arranged side by side.

[0027] A clearance hole 13 is provided in the middle of the cushion body 1. When the seat cushion 1 is installed on the baby stroller, the middle tube of the baby stroller can pass through the clearance hole 13 for easy installation.

[0028] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
