Description

a fan

technical field

The present invention relates to the field of household appliances, and more specifically relates to a fan.

Background technique

There are usually two types of fans, ceiling fans and floor fans. In order to facilitate people's use and portability, there are also miniature fans. No matter what kind of fan is, the rotation of the fan blades makes the air flow, thereby generating wind, but this wind is still the same as the air. The same temperature will not make the user feel cool.

I have designed a fan with a water spray device, which can spray mist water by extrusion. The water spray device includes a water spray pipe, a nozzle that is sleeved on the top of the water spray pipe and partially embedded in the bottom of the water spray pipe. Hole for suction hose. The water spray device is fixed in the casing of the fan, and the casing includes a front casing and a rear casing fixed by heat fusion, and the motor on the fan is directly fixed by the fixing of the front casing and the rear casing. This program is unpublished. Since the motor is fixed by the front shell and the rear shell, when the fan is working, the internal rotation of the motor will cause the motor to vibrate, and the fixation of the front shell and the rear shell to the motor is not firm enough to make the motor shake, which will cause the fan to vibrate. Work is unstable.

Contents of the invention

The technical problem to be solved by the present invention is to provide a fan firmly fixed to the motor.

The purpose of the present invention is achieved by the following technical solutions: a fan, the housing of the fan is provided with a placement slot for placing the motor, and the fan also includes a fixing device for fixing the motor.

Preferably, the fixing device includes a hardware piece arranged on one side of the placement groove for pressing the motor. The metal sheet presses one side of the motor, and the other side is close to the side wall of the placement slot, so that the metal sheet can make the fixing of the motor more firm.

Preferably, one end of the metal piece is in close contact with the motor, and the other end is fixed by a locking structure. The metal piece is first firmly fixed, and then cooperates with the motor to fix the motor.

Preferably, one end of the metal piece is outwardly provided with a fold close to the motor, and the fold and the body of the metal piece can be bent toward the fold direction. Put the side where the motor is in contact with the metal piece into the placement slot first, and put the other side of the motor into the placement slot by squeezing and folding it. The hardware piece has good elasticity in its folded part, so that the folding and hardware There is a certain shrinkage between the chip bodies, so that the motor will be firmly fixed in the placement slot to prevent the motor from shaking.

Preferably, the locking structure includes a baffle that is in close contact with the side wall of the hardware piece, a slot for placing the other end, and an opening for placing the middle part of the hardware piece. This is a specific structure of the clamping structure, so that the clamping structure is set so that the hardware piece is firmly fixed at the clamping structure.

Preferably, one side of the opening is the baffle plate, and the other side is a limiting column, and the hardware sheet is provided with a convex point corresponding to the limiting column, and the limiting column is provided with a point of depression. The metal piece is pressed downward from the opening and placed between the limit post and the baffle. The upper end of the limit post is set smaller to facilitate the insertion of the hardware piece; The other end of the piece is limited by the card slot, and then the fixing of the hardware piece is more firm through the limiting column, the depression and the card slot.

Preferably, the limiting column gradually increases from its top downwards. Enlarging the lower part can increase the strength of the limit column, and the upper part is provided with a small convenient hardware piece to be inserted from the opening.

Preferably, the bumps are hemispherical. This is a specific structure for setting bumps, so that the depression is also a hemispherical structure, so that the bumps and the depressions can be tightly matched; and the spherical structure has a certain arc shape, and the bumps of the arc-shaped structure have It is beneficial for the metal piece to be placed between the limit post and the baffle and to cooperate with the depression.

Preferably, the lower end of the limiting post is integrally connected with the baffle, and the hardware piece is placed at the connection. This setting is used to limit the position and prevent the hardware piece from being forced down too much due to excessive force, so that the folded part of the hardware piece can be located in the middle of the motor, so that the limit effect is better.

Preferably, the hardware sheet is provided with a hemispherical groove at the raised point. Provide grooves for weight reduction.

In the present invention, the motor in the fan is limited and fixed by the placement slot first, and then the motor is further fixed by the fixing device, so that the motor can be fixed more firmly, and the motor is not easy to shake during operation.

The reinforcement columns are cylindrical structures; the roots of the reinforcement columns are provided with reinforcement ribs, which can further increase its strength. The number of reinforcing ribs is two, and they are arranged oppositely. The structure of the reinforcing ribs is a right-angled trapezoid, and the longer right-angled side is in contact with the reinforcing column, so that the strength of the support plate can be increased. Of course, other numbers of reinforcing ribs, such as one, three, etc., can also be provided; the reinforcing ribs can also be provided in other structures, such as a bar-shaped structure. In contrast, setting the ribs with a right-angled trapezoidal structure can increase the strength of the roots more, so that the effect is better.

As shown in Figure 2, a handle 8 is provided on one side of the front shell 2. Referring to Figure 5, one end of the handle 8 is provided with a locking wall that cooperates with the protrusion 111, and the locking wall cooperates with the protrusion 111, so that it is convenient to press the nozzle 11 to spray. The water device 1 sprays mist water. The other end of the handle 8 is provided with a pin shaft, and the front shell 2 is provided with a groove matching with the pin shaft, so that the handle 8 can be rotated through the pin shaft. The outer surface of the middle part of the handle 8 is provided with an inward depression, and the depression is arranged in cooperation with people's fingers, so that it is convenient for the user to press the handle with fingers. The bump 111 is provided with a slot 112, which can reduce the weight, and a connecting plate 113 is provided at the slot 112, which can increase the intensity of the bump 111.

The front shell 2 and the rear shell of the present invention are fixed by hot-melt, and the hot-melt fixation is firm, and the sealing effect is good, so that the liquid in the water tank can be avoided from leaking out. As shown in FIG. 2 , the front shell 2 is provided with a liquid injection hole 23 at the water tank, and the liquid injection hole 23 is a through hole with a circular structure, which is convenient for injecting liquid into the water tank. The liquid described in the present invention is water, and perfume, toilet water and the like can also be added to the water. Therefore, when the liquid is blown to the user with the wind of the fan, not only can the user feel a cool feeling, but also can overflow with fragrance, giving people a sensory enjoyment.
