Description

本实用新型涉及一种改进的、具有自然风特点的电扇。 The present invention relates to an improved, having the characteristics of natural wind fan.

在现有的电扇中,模拟自然风的电扇有两种,一种是在普通电扇上加装电子开关,该开关以一定的规律给电扇的电机供电,使电扇时开时断,以形成时大时小的风量;另一种是在电扇的扇叶前加一个慢速转动的转叶,以改变风的角度。 In a conventional fan, the simulated natural wind, there are two fans, one is the installation of an electronic switch in the ordinary fan, the switching power supply to the motor of the electric fan to certain rules, so that when the fan off when open, to form large small air volume; the other is in front of the fan blades plus a slow rotation of the rotary vane, to change the wind angle. 上述电扇形成的风虽然有大小及方向的变化,但都是扇叶形成的风直接吹到人身上,风向前的速度较大,而对于某一空间位置,风持续的时间又较短。 Wind Wind fan formed although the magnitude and direction changes, but the blades are formed directly blown person, the larger the wind speed forward, while for certain spatial position, and a shorter duration of the wind. 因此,有风时则感到风很硬,无风时便感到很热。 Therefore, when the wind is very hard to feel the wind, it was very hot when there is no wind.

本实用新型目的是提供一种立体风源,使风向前吹的同时,又有一个大小可变的横向速度,犹如人工煽扇一样,使人处于徐徐和风之中;并且在电扇的四周均匀可吹到风,风也较凉快;该电扇也较一般电扇安全可靠。 The present invention aims to provide a three-dimensional air source, so that while the forward wind blowing, but also a lateral speed of variable size, like a fan as artificial fan, among people in the wind slowly; and four weeks may be uniform fan wind blowing, the wind is generally cooler; also secure the fan than the average fan.

本实用新型采用普通的电扇装置,即由扇叶和电机组成的装置,扇叶与送风管道一端相通,使风经过该送风管道,在送风管道的另一端接一个可左右转动的风柱,风柱的四周分布风口和隔室,顶部有顶盖,风从风口出来形成一股具有上下一定高度,左右一定宽度的气流。 The present invention means the ordinary fan, i.e. a fan and a motor means consisting of blades and the air supply duct communicating at one end, so that wind passes the air duct, the air duct at the other end around a rotatable wind column four weeks, air distribution and air column compartment, the top cover, out of the wind outlet is formed from an upper and lower having a height, a width of about airflow. 当风柱相对于送风管道左右转动时,这股风就象煽扇子的风一样,柔和地送到人体上,使人感到凉快和舒适,风柱相对于送风管道左右转动主要是通过风柱底部的一对永久磁铁与两对电磁铁之间的相互作用而实现的。 When the rotation of the wind relative to the column about air duct, which shares the wind like the wind, like a fan fan, gently onto the human body, people feel cool and comfortable, air column rotating relative to the left and right air duct mainly by wind pair of permanent magnets at the bottom of the column and the interaction between the two pairs of electromagnets realized. 两对电磁铁的极性和频率用电子控制器控制。 Two pairs of electromagnets controlled by the polarity and frequency of the electronic controller.

如图1所示,本实用新型的自然风电扇主要由电机[1]、扇叶[2]、送风管道[3]、电磁铁[4]、永久磁铁[6]、风柱[7]、顶盖[8]和电子控制器[12]组成。 1, the present invention is mainly composed of natural wind fan motor [1], the blade [2], the air supply duct [3], the electromagnet [4], the permanent magnets [6], the wind column [7] the top cover [8] and an electronic controller [12] the composition. 电机[1]、扇叶[2]安装在电扇的下部,电机[1]由支架[14]安装在底座[15]上,外用安全罩罩住,安全罩[11]上开有进风口[13]。 A lower motor [1], the blade [2] is mounted on the fan, motor [1] by the bracket [14] is mounted on the base [15], the external cover covers the safety, security cover has an air inlet opening [11] on [ 13]. 安全罩[11]上端通过螺纹与送风管道[3]连接,螺纹连接可调节电扇高度。 Safety cover [11] and an upper end by a threaded air supply duct [3], screwing the adjustable height fan. 送风管道[3]把风送至风柱[7]。 Air supply line [3] to the wind lookout column [7]. 送风管道[3]上部置有塑铸在磁靴[5]中的两对电磁铁[4]和风柱[7],风柱[7]下部塑铸有一对永久磁铁[6],这对永久磁铁[6]与其下面两对电磁铁[4]相互作用,即同时改变两对电磁铁[4]的极性,使永久磁铁[6]和两对电磁铁[4]在同性相斥、异性相吸的作用下,带动风柱[7]相对磁靴[5]左右转动。 Air supply duct [3] has set an upper magnetic piece plastic casting [5] in the two pairs of electromagnets [4] wind column [7], air column [7] a lower plastic cast having a pair of permanent magnets [6], which is permanent magnets [6] the following two pairs of electromagnets with their [4] interaction, i.e. while changing the polarity of the two pairs of electromagnets [4], the permanent magnets [6] and two pairs of electromagnets [4] in repel each other, under the action of opposites attract, driven by the wind column [7] is rotated relative magnetic piece [5] or so. 风柱[7]摆动的频率及幅度由电子控制器[12]控制。 Wind column [7] and the amplitude of the wobble frequency [12] controlled by the electronic controller. 电子控制器[12]是一双基极振荡线路(见图5),其负载为一个继电器,继电器的两组常开常闭外接点形成一个换极性开关,当继电器交替吸合与断开时,直流电压便交替地以不同的极性给电磁铁[4]的两组电磁线圈供电,致使电磁铁[4]的极性交替变化。 The electronic controller [12] is a pair of oscillating base line (see FIG. 5), the load is a relay, the two normally open normally closed relay external switching points form a polarity change, when the relay is disconnected alternately absorbed and two sets of solenoid power supply, a DC voltage will alternately different polarities to the electromagnet [4], resulting in the electromagnet [4] of alternating polarities. 风柱[7]转动的频率由振荡线路的频率决定,转动的角度由电磁铁的对数决定。 Wind column [7] rotational frequency determined by the frequency of the oscillation circuit, the angle of rotation is determined by the number of electromagnet. 当磁铁为两对时,风柱[7]转动45度角。 When the two pairs of magnets, the wind column [7] is rotated 45 degrees. 电子控制器[12]可安装在安全罩[11]内。 The electronic controller [12] may be installed in a safety cover [11] within. 风柱[7]四周均匀分布8个风口[9]和隔室[17],电扇的风经风口[9]吹出。 Wind column [7] four weeks uniformly distributed outlet 8 [9] and the compartment [17], the fan wind outlet through [9] is blown. 风柱[7]顶部有顶盖[8]。 Wind column [7] has a top cover [8]. 风口[9]的个数可视具体情况选择,亦可用档板调节风口[9]的大小和个数,档板可以安装成滑动式。 Tuyere [9] to select the number depending on the particular circumstances, also with adjustable air baffle [9] The size and number, baffles may be mounted slidably. 风柱[7]和磁靴[5]由送风管道[3]上部的凸台[18]和固定圈[10]固定在送风管道[3]的上部。 Wind column [7] and the magnetic piece [5] by the air supply duct [3] in the upper portion of the boss [18] and the retainer ring [10] fixed to the upper air supply duct [3]. 整个电扇安装在带有滚轮[16]的底座[15]上,滚轮[16]为4个。 Entire fan installed in [15] on a stand with rollers [16] and rollers [16] is four. 扇叶[2]中心轴与送风管道[3]中心轴垂直,送风效果较佳。 Blade [2] with the central axis of the air supply duct [3] a vertical center axis, the air blowing was better.

本实用新型的自然风电扇亦可制成台扇式和壁式,但不需要安装滚轮。 The present invention can also be made of natural wind FANS type fan and wall, but do not need to install the roller. 此外在风扇的高度上要作些调整,以适合台扇用。 In addition, in the height of the fan to make some adjustments to suit a desk fan.

本实用新型的扇叶[2]、风柱[7]、送风管道[3]、顶盖[8]、磁靴[5]、隔室[17]可用金属材料或塑料制成。 Blades of the present invention [2], the wind column [7], the air supply duct [3], a cap [8], the magnetic piece [5], the compartment [17] is made of metallic material or plastic. 扇叶形状可以是排风扇叶、亦可为其它形式的扇叶,如长距形等。 Exhaust fan blade shape may be, may also be other forms of blades, such as long distance shape.

综上所述,本实用新型形成的风从风口出来。 In summary, the present invention is formed by air from the air out. 具有纵向和横向两个速度,其中心运动轨迹不再是直线,而是曲线,所以就象风洒在人身上一样,很柔和;电机和扇叶封闭在安全罩内,使用安全;风通过风柱可实现360度立体送风;当电扇是落地型时,风从底部进入,吹出的风较凉快。 Having two longitudinal and lateral velocity, the central trajectory is no longer straight, but curved so as sprinkled in the human body, like wind, very soft; fan motor and enclosed within a safety cover, the use of safety; wind through the air column 360 may be implemented dimensional air; when the fan is a type of floor, air enters from the bottom, more cool air blown out.
