Description

Electric fan

Technical field

The utility model relates to an electric fan, in particular to a multifunctional electric fan which is convenient to operate and safe to use.

Background technique

At present, there is no remote control fan with directional, yaw, pitch, wave and other wind-like changes in the market, and the structure of the fan with the above-mentioned wind-changing is limited to the manual pump-type gear combination structure, and the pumping operation It is necessary to use the cooperation of the electromagnetic device to achieve the wind change by remote operation.

Utility model content

Although this design combines with the gearbox, it has the functions of directional, yaw, pitch, wave and other wind-like changes, but its structure can also completely or partially exclude the gear combination of the gearbox, and change it to a blower motor. Two gear motors, one of which is longitudinally driven, matched with the support, and the longitudinal plate sleeve and the connecting rod are pinned and then the center distance of the crank arm is taken as the pitching amplitude, and the front arm of the supporting seat is positioned on the motor Side as a pendulum positioning center. Another gear motor drive shaft positioned on the horizontal vertical plate horizontal plate seat is extended by the yaw shaft after the yaw arm is screwed through the guide groove or the duct group, and the yaw positioning is centered on the lower vertical axis of the support. The change in wind shape is determined by whether the conductor is electrically conductive or not. Exclude the original gear with the gearbox and the spring double ball from the drawbar of the tension bar. Although the market sells a single-shaped remote-controlled electric fan with a mouth-shaped or horizontal figure-eight shape, it also uses a blower motor to fix the two-gear motor, and the traverse arm of the traverse arm and the fulcrum are provided on the guide plate j 11 because the guide plate is not longitudinally elastic. The ditch moves forward and backward to solve the clever operation of the vertical and horizontal swing force conflicts, so the fans of other brands with gear motors cannot blow out the pendulum or the wavy wind.

The original gearbox structure and the multi-function fan driven by the gear motor are the creations of the same group of creators: In order to make the large, medium and small electric fans have the orientation, yaw, pendulum, wave blowing function, Two series of research and development of mechanical transmission and electronic transmission, among which the gear transmission series has entered the second application for rights, and the gear box type transmission fan adopts the pumping type shifting. If the remote control unit is equipped with two electromagnets and the gearbox and other related components, the price difference of the remote control structure using the gear motor is more than 50 yuan, and the cost of the creation of the product will be favored by consumers.

The air blower motor is fixed with two gear motors, wherein a gear motor is positioned at a rear side of the blower motor, and a longitudinally extending drive shaft is screwed by one end of the upper and lower links of the crank arm, and the other end is made of a front end The special screw with the teeth and the back tooth is positioned on the sleeve of the extension plate after the support, and the longitudinal structure is the same as the front side of the blower motor with the screw hole of the two front arms of the support The forwardly-extending twisting ring hooked under the front arm is screwed together by the above screws, and the front and rear weights of the pitching pitch are standardized by the combination of the middle portion of the extended inner spring and the upper end of the rear housing of the motor or the positioning of the lateral vertical plate slot. Balance, match the guide plate and the yaw arm to operate vertically and vertically. If the traverse arm and the guide groove form a curved angle, the vertical air blow will blow out the oblique vertical wind.

The blower motor is fixed to the two gear motors, and the horizontal plate seat which is located slightly below the center of the vertical plate seat, so that the lower end of the drive shaft is swayed by the yaw arm and the other end support shaft penetrates the guide groove. The front and rear extension ears of the guide plate are extended from the two sides toward the inner side of the guide plate, and the elastic force of the spring in the opposite pressure groove is centered on the screw, forcing the rear portion to be upturned, thereby preventing the guide plate and the rear portion of the base. Friction, at the same time, the support shaft penetrates the guide plate and fits the lower end of the copper tube, and is pinned by a padding screw under the guide plate for the yaw positioning and steering.

Although the creation of the two-gear motor replaces the structural function of the original gearbox set, the same wind-like change is achieved. Therefore, in addition to the front and rear grille, fan blades and related components of the fan assembly, the air blow is used. When the motor is used in a two-gear motor, the rear extension shaft is shortened and replaced, and the two gear motors replace the original gear assembly function. However, for the diversification of the model, the original blower motor can extend the rear shaft to engage the right clutch gear, so that the inner edge concave groove is engaged with the spring double of the middle of the vertical swing shaft relative to the cam. Bead drive, the outer flange of the lower part of the coaxial sleeve is fitted with the inner hole of the helical gear, and the meshing transmission arm of the top two helical teeth extends to the right end of the screw-joining link of the column, and the other end hole is screwed to the rear of the support. The structure of the plate sleeve is made up of the pitch of the pitching and steering, and can replace the transmission function of the original pendulum gear motor, and is matched with the yaw gear motor group and the guide plate of the horizontal plate seat device outside the gear box, that is, The yaw of the yaw gear motor can be yawed, matched with the pitch gear of the gearbox, and the wind speed of the blower motor is changed. The fixed speed yaw of the yaw gear motor is matched with three different numbers of rotations: high, medium and low speed. It can change with the wind speed, blowing different wave winds is an unprecedented function; the multi-function fan has up and down pitch, the wave swings back and forth, to avoid the front and rear of the first vertical neck against the front of the outer shroud base The gap is very easy for children's fingers or intrusion into the electric shock by the bar. For the safety concept, one of the four different types of skateboards is selected to prevent it.

The upturned skateboard is matched with the horizontally notched fan net holder: The difference between the skateboard and the original gearbox transmission is that the horizontal diameter of the front end of the skateboard is added, and the smooth and horizontal movement can be completely eliminated. The sharp angle of the front end of the original skateboard and the rough surface of the fixed seat and the abolition of the original track column and the up and down channel can improve the jerk problem, and increase the bank edge of the inner bank of the longitudinal groove on the two sides of the horizontal wall of the fan frame. The section is provided as a sliding path on the skateboard to completely solve the friction caused by the friction of the skateboard. The rear section of the skateboard is provided with a diameter hole and a sleeve is set, and the rear section of the skateboard is set to be front and rear to the Chuangou for the base. The extended T-shaped lip is used as a track to control the upturn of the skateboard.

Two-piece skateboard: It is composed of two front and rear slides stacked together. The front block skateboard front end can be fixed to the back side of the seat back, and the following horizontal notch can be used as the front and rear block skateboard front section telescopic track. It is equipped with a lip to prevent it from falling off when it is moved backwards. However, on the two sides of the rear section of the front skateboard, each of the front and rear channels is engraved, and the upper part of the front side of the skateboard is stretched with the τ word. The radial hole of the rear block is pierced by the first longitudinal neck of the sleeve, and the front and rear swinging process is performed, and the sliding plate can completely cover the U-shaped notch function of the front section of the base. Decomposed head: In order to insert the first longitudinal neck without the need for a cut in the above-mentioned slide hole, it is necessary to form a top cover portion and a lower neck portion, and the slide plate is firstly inserted from the upper portion of the neck, and then the top cover portion is extended. The positioning rod and the screw are screwed together, and as long as the lower part of the neck is replaced, it can be combined with the gap specifications of the upper end of each brand of the fan foot or the switch box.

Generally, the blower motor is used, although a gear motor is added, but the wind direction changes such as orientation, yaw, pitch, and wave are not always achieved, and the gear-driven fan or the blower motor back-fixed two-gear motor created by the creators respectively The components, because of the use of a guide (direction controller) can achieve the above functions, and other brands also use a blower motor to fix the two-gear motor can not achieve the above-mentioned wind shape is not added to the creation of the guide.

The function of the guide plate is in the present creation: the reason why the electric fan will reciprocate and yaw is that the front extension ear and the front extension ear are screwed by the two sides, and the front extension spring plate with the guide front is extended by the torsion spring. Press down on the two side screws to force the upper arm of the guide plate to lean against the bottom of the yaw arm. It can also be placed under the guide plate with the arc type gasket and the pad spring with the padding screw and the sleeve. The copper pipe positioning also has the same upturning function, and the yaw arm support shaft is positioned and positioned in the guide channel, so that the crank arm rotates once around the support shaft in the channel, that is, the reciprocating yaw once, but the horizontal The width of the pendulum is the radius of the distance between the axis of rotation of the crank arm and the fulcrum, and then the vertical line of the yaw center is the base point of the yaw and the position of the other side of the arm is centered on the lower vertical axis of the struts. The width of the blower stays in front of or behind the Chuangou is different. Therefore, when the wind contact point of the winder changes at any time, it feels cooler than the conventional fan. Therefore, when the fulcrum is turned at the front end of the Chuangou, the return stroke is particularly accelerated, that is, the radius between the fulcrum and the lower longitudinal axis is the shortest, that is, the yaw of the yaw is accelerated by the slow rush and then slowed down, and the yaw is generated in the first part. A yaw easing seat is arranged on one side or two sides, and a front and rear inclined lip is arranged under the horizontal plate of the struts to relatively relax the seat surface to be low and high, and the friction of the fan head is pressed from the yaw returning path. The problem of efficiency is solved. The yaw arm support shaft of the pendulum blowing process is continuously displaced back and forth between the guide groove and the pitch of the fan head The movement can make the fan head group make the above-mentioned wind-like change. On the other hand, if there is no positioning and steering of the guide plate and the swinging of the elastically-adjusted fan head, the wave-shaped wind cannot be blown by the fixed length, and if the hardness is to be blown by the wave, the card will be stuck. Live and malfunction. This creation has the configuration of the first guide plate, so that the wave swings smoothly, but with the configuration of the full-arc guide, when the yaw arm and the guide groove form a 90-degree angle, it is also the guide rear end when the yaw is extreme. The traverse to the widest position will result in the widening of the outer shroud and the rear end of the base. In order to prevent the front cover from following the hypertrophy, a protruding cup on the rear side of the rear section is provided with a curved guide. However, the smaller type, such as the 14-inch fan, is suitable for the telescopic guide plate, and the telescopic guide plate is made up of the inner and outer female guide plates. The front end of the female outer guide plate is provided with the front extension ear and the first part of the extension and the second ear. The special screw of the back section is screwed so that the spring plate in front of the ear of the guide plate is pressed by the opposite spring by the opposite spring, and then the upper part of the guide plate is pressed against the bottom of the curved arm with the screw as the center. However, the fulcrum of the yaw moment is not moved back to the rear end of the sub-guide plate that pushes the center, so the rear section of the hood can avoid the molding of the bulging cup, so the hood can be integrally formed and suitable for the configuration of the small-sized fan.

The circuit board is disposed in the switch box or is relocated in the foot socket, and is respectively extended by the power socket with the anode wire, that is, the anode wire is passed through the capacitor input motor, respectively, and is respectively outputted to the common end, and is transferred to the circuit board and further bifurcated. To two gear motors. The cathode wire directly enters the circuit board, but the circuit board that is respectively discharged by the blower motor is divided into low speed, medium speed, high speed, and the power switch is powered off by pressing the left button of the lower part of the circuit board as the power off button. There is a high-speed or medium-speed or low-speed conductive rotation speed change, the third button is a timing button, and the fourth button is a circuit board connected to the yaw gear motor, and each time the press is placed, there is a conductive and power-off rotation. The fifth button is the circuit board wiring. The pendulum gear motor, the sixth button is the temperature control rotary button, which can be rotated to set the lower limit temperature and automatically stop. The button can also be abolished and replaced with negative ion germicidal lamp.
