Description

M407299 V. New description: [New technical field] This creation department is related to fans, especially the suction motor through the air inlets, and then the air outlets to blow air to form a leafless fan. [Prior Art] A general fan has a base on which a support frame is disposed. The support frame supports a motor and a plurality of leaf fans. The motor drives the fan blades to rotate, so that the nearby air is accelerated and flows. The cool breeze, while the motor drives several leaf blades to rotate at a very fast speed, due to the wounding of the leaf fan under high-speed rotation. Some people who have improved the above-mentioned fan have improved the outer casing of the fan blade to avoid direct damage. However, the child may still be curious to put his finger into the mesh casing, and the speed is very fast. Fan wounded. How to blow the cool breeze 'but not let the children accidentally touch and create safety concerns' is a big topic · [New content] The main purpose of this creation is to have no general fan, to avoid children accidentally touching Safety concerns can be seen as a safety fan. The secondary purpose of this creation is to have air intake and air outlets to increase air volume, reduce the burden on the pressurizing motor and extend the service life of the machine.良, ^ The above two, for providing a leafless fan structure modification includes a base, the base is provided with a receiving slot; a support frame, standing on the base 'support frame, the support frame has - accommodating space support control one complement B * Han Yi 恻 extends upwards, the other end of the air duct has - first air inlet and - air duct: sea air duct, the first air duct and the first Two-way second ventilation :一:::成ΐ通, in the first ventilation pipe and the

Extending a first ventilation pipe (2 4 ) and a second ventilation pipe (25), the = ventilation pipe (24) and the second ventilation pipe (25) are formed by the installation space (2 2) In the first ventilation pipe (24), the other end has a first air inlet (26), and the other end of the second air duct 25) has a first air outlet (27). s plus a frame (3 0 ), the frame (3 〇) is set on the support 々 = (2 0 ) 'the frame (3 〇) is a hollow annular body;; (2 ◦) is provided with a relative position - the second air inlet = two air outlets (1)), the second air inlet (3ι) ί: 兮: air outlet. (3 2 ) respectively connected to the first air inlet (, the first air outlet (27) , the 6 4). The air inlet (3 3 ) and the third air outlet (J motor (4〇) are disposed in the accommodating space: 'The pressure motor (4〇) has a 匕, (2 the locking stud runs through the bulge I 4 1 ), the spear makes the pressurizing motor (4 Q 疋 体 body (2 3 ) _ the pressurizing stirrup ( 4 〇)) and has a suction end in the accommodating space (2 2 ) ' ) (4 2 ) and a 5 M407299 = the pressurizing motor (4〇) controls the operation and the rotational speed of the pressurizing motor (4Q) by the control device (2 0 1). ...the second is an overview of the structure, location, and interconnection of each component of the creation; then, the combination of the various components of the creation and the expected benefits are stated as follows: =Following to continue to refer to the first to fourth In the figure, by using the above-mentioned component 2, the operation of the pressurization=4" is started by the control I (2 0 1 ), and the third air inlet (33) sucks in the air and enters the frame. ), and through the second air inlet (3 1 ), the first air inlet (263 to η ^ . μ, to the first air duct (24), from the wind end U2) The motor (4 〇) is pressurized, and the air is supplied from the air supply end (4 3 ) through the second air duct (2 5 ), the first air outlet (27), the flute - 4ικ?. The first air outlet (3 2 ) is blown out by the 5th second air outlet (34). Since the creation uses a pressurized motor to suck the air through the air inlets, and then the air outlets blow air to form a wind flow, the pressure motor is In the bracket, none of the fans with fan blades can prevent children from accidentally touching; the safety concerns can be regarded as a kind of safety fan. Wind and air outlets, increase air volume, reduce the burden on the pressurizing motor and extend the life of the creation. This creation can be set as shown in the fifth figure before the air supply end (4 3 ) and the second air outlet (3 2). A third ventilation pipe (5 〇) is provided. The third ventilation pipe (50) is formed in the second ventilation pipe (25) to reduce the noise and increase the wind speed and the wind pressure. In summary, the creation In line with the provisions of the Patent Law, Mai Yi went to 6 to apply, and hoped to grant patents as early as possible.
