Air blast building block unit

Abstract

An air blast building block unit comprises an air blast building block, a motor building block and at least one air collecting accessory. The air blast building block is provided with an air inlet and at least one air outlet. The motor building block is used for driving the air blast building block to produce air flow entering and exiting the air blast building block. The air collecting accessory is communicated with one out of the air inlet and the air outlet, and provided with a chamber communicated with outside, and the chamber forms a medium guiding the air flow to enter relative to the air inlet, and a medium guiding the air flow to exit relative to the air outlets. Therefore, the unit can be combined with several building blocks into a building block assembly according to different subjects, with the adoption of variability of effects of the air collecting accessory, the air inlet and the air outlet, a building block toy with an indraft effect (such as a dust collector) and an air exhaust effect (such as a hovercraft) can be created, a child can be taught to realize the effect of the air flow, the high originality can be exerted, and the purpose of teaching through lively activities can be reached.

Description

technical field [0001] The invention relates to a building block, in particular to an air blowing building block unit capable of creating a building block toy with air suction and air exhaust effects. Background technique [0002] refer to figure 1 , taking the hovercraft toy 1 of China Taiwan Early Publication No. 200944276 as an example, it mainly includes a base 11, a fan 12 arranged on the base 11, a motor 13 for driving the fan 12, and a supply for the fan 12. A battery 16 for required power, and a skirt 18 mounted on a periphery of the base 11 and defining a ventilation space 17 with the base 11 . The fan 12 has an air inlet 121 opposite to the ventilation space 17 . [0003] When the motor 13 drives the fan 12 to rotate, the air flow will flow from the front to the rear of the fan 12, and fill the skirt 18 from the air inlet 121, so that the skirt 18 will expand due to inflation. In this way, the whole is floated on a plane due to the effect of airflow, so as to ac...

Problems solved by technology

[0004] It is worth noting that the airflow in nature will produce different forces such as suction or blowing due to different flow directions. However, although the aforementioned early public case is a toy, it can only be limited to one shape and display one. The effect of airflow (blowing) not only has limited changes in shape, but also cannot achieve the purpose of teaching and displaying for the above-mentioned different airflow effects. Therefore, there is still room for great improvement in the creativity that can be exerted and the effect of entertaining and teaching
