Definitions
- This invention relates to a sleep fan, and more particularly to an energy-saving, quiet, and highly adaptable tool for generating flowing air to a specific location.
- the system has a base portion in which is housed a fan that allows at least one of the surrounding air to flow upward.
- the base portion has an inner hollow portion and at least one air inlet through which air flows in.
- the device can be used to generate flowing air to a desired location.
- the device has some drawbacks.
- the system can have more than one fan and an air inlet corresponding to each fan, all of the fans and air inlets must be disposed on one side of the base portion. The back of each fan must be closed to create air flow.
- each fan corresponds to one air inlet, and there should be no more or less, and the area of each air inlet must be substantially the same as the area of the corresponding fan.
- Larger air intakes reduce airflow formation, while smaller air intakes reduce fan efficiency.
- the resulting structure is that the airflow through the air inlet and the fan will be faster.
- the apparatus provided is capable of having a larger air intake area to enable reduced airflow speed.
- the larger air intake reduces the speed of the airflow, which reduces the noise generated by the airflow and saves the energy required by the fan to produce high velocity airflow.
- the main technical problem to be solved by the present invention is to provide a sleep fan with high applicability.
- an object in the surrounding environment obscures the side wall of the sleep fan, the user does not need to move or rotate the sleep fan.
- Another technical problem to be solved by the present invention is to provide an energy-saving and quiet sleep fan.
- the fan has a larger inlet area that is independent of the fan blade area.
- the fan achieves lower air flow rates for quietness and energy savings.
- the present invention provides a sleep fan, which
- the housing includes a base having a base and a body extending upwardly from the base.
- the base has a pair of side walls spaced apart from each other and a bottom surface that can be placed over the ground.
- the sleep fan further includes a cross flow fan disposed between the pair of side walls, the cross flow fan having an axis substantially parallel to the bottom surface and the pair of side walls.
- the sleep fan further includes a plurality of air inlets, which are opened on the side walls at positions corresponding to the cross flow fans.
- the sleep fan also includes a motor that is placed within the base and drives a cross flow fan.
- the sleep fan also includes an air guiding device having a body slidably disposed over the dry body and a head portion at an angle to the body.
- the beneficial effect of the invention is that the total area of the plurality of air inlets is no longer related to the area of the fan, and the total area of the air inlet becomes larger and flows through at the same time as the flow rate of the conventional fan.
- the airflow rate at the air inlet is greatly reduced. This significantly reduces the wind drying caused by the air flow.
- the speed of the intake air flow is reduced, the required cross-flow fan speed can also be reduced, and the power consumption of the motor can also be reduced.
- the position of the back of the conventional fan on the outer casing no longer needs to be closed, and the air inlet can be opened on both side walls. When an environmental object obscures the side wall of either side of the base, the user no longer needs to move or rotate the entire sleep fan.
- the sleep fan has a stronger ability to adapt.
- FIG. 1 is a perspective view of a preferred embodiment of a sleep fan of the present invention.
- Figure 2 is a cross-sectional view of the sleep fan shown in Figure 1. as well as,
- Figure 3 is a perspective view of the explosion of the sleep fan shown in Figure 1.
- a preferred embodiment of the sleep fan 1 of the present invention has a housing 10 and a housing 10 There is a base 11 and a dry body 12 extending upward from the base 11.
- the base 11 has a pair of side walls 13 spaced apart from each other and a bottom surface 14 that can be placed above the ground.
- a cross flow fan 20 is placed between a pair of side walls 13 of the base 11, and the cross flow fan 20 has an axis 21 which is substantially opposite to the bottom surface 14 and the two side walls 13 Parallel.
- a plurality of intake ports 15 are formed in the side wall 13 of the base 11 at a position corresponding to the cross flow fan 20.
- the cross flow fan 20 also has an air outlet conduit 22 in communication with the dry body 12 22 .
- the cross flow fan 20 is driven by a motor 23 placed in the base 11. Although in accordance with the principles of the present invention, cross flow blower 20 It can be driven by any motor, and it is preferable to use an energy-saving motor.
- the motor 23's switch, speed and or operating time can be installed in the sleep fan 1 housing 10
- the remote controller or remote control is used for control. Fan control belongs to the prior art and will not be described in detail herein.
- a bracket 30 is disposed between the cross flow fan 20 and each of the side walls 13. Each bracket 30 An air filter 31 can be mounted on the top.
- the present invention also has an air guiding device 40 having a body 41 slidably sleeved over the body 12 and a body 41 An angled head 42 that is used to direct air flow to a particular area.
- the user can place the sleep fan 1 of the present invention in a designated position and then adjust the height and direction of the head 42 to make the head 42 towards a specific area where air flow is required.
- the motor 23 is turned on, the cross flow fan 20 starts operating.
- the surrounding air enters the cross flow fan through the air inlet 15 opened on a pair of side walls 13 separated by a certain distance. 20, then the air flow flows upwards, through the air outlet duct 22, the dry body 12 of the outer casing 10, and the air guiding device 40, and finally flows out from the head 42 and blows toward a specific area.
