Description

Micro vacuum cleaner

[Technical Field]

The present invention relates to the field of vacuum cleaners and, more particularly, to a micro vacuum cleaner. 【Background technique】

With the improvement of people's living standards, the computer penetration rate has increased year by year, and it is inseparable from work and life. And the style of computers is now more and more, such as desktop, portable and so on. When the computer is in use, dust or other impurities in the air can easily enter the keyboard, the chassis or the display. Do not clean the dust for a long time will affect the normal operation of the computer. Both the main unit and the display are bulky, and dust can be removed using conventional methods. However, there are many gaps on the keyboard, and the gap is small, and it is difficult to remove the dust in the keyboard by a conventional method. However, when the user taps the keyboard, the dust in the gap of the keyboard may be taken out, so that the user's finger is contaminated with dust; and the dust in the gap of the keyboard may enter the inside of the keyboard, and the inside of the keyboard is set. The circuit, which in turn affects the life of the keyboard.

I have designed a micro vacuum cleaner comprising a body and a blade disposed inside the body, a motor driving the blade, a data line plug for supplying power to the motor, and a tip disposed at an end of the body, wherein the tip It is connected with the blade. The data cable plug is soldered to the motor through the wire. As long as the data cable plug is directly inserted into the data line interface, it can be used without other power supply. The motor includes the end of the motor. a rotating shaft, wherein the blade is provided with a shaft hole closely fitting with the rotating shaft, and the blade is thermally fixed on the rotating shaft of the motor; the motor is fixed in the main body with glue, and an air suction port is arranged at a corresponding blade position of the main body, so that the motor is arranged at the motor When the driving blade rotates, it can drive the rotation of the surrounding air to form a required negative pressure environment. This program is not public. Since the motor is fixed in the interior by using glue, the adhesiveness of the glue may be lowered for a long time, and the fixing of the motor inside the main body is not firm; and the micro vacuum cleaner needs to move frequently when used, once the motor is not firmly fixed. , it may affect the normal use of the vacuum cleaner.

[Summary of the Invention] The technical problem to be solved by the present invention is to provide a micro vacuum cleaner that securely fixes a motor. The object of the present invention is achieved by the following technical solutions: a micro vacuum cleaner comprising a main body and a blade disposed inside the main body and a motor for driving the blade, wherein the main body is internally provided to be adapted to the motor The limiting portion has a tight fit between the limiting portion and the motor.

Preferably, the limiting portion includes a first baffle and a second baffle disposed in parallel, and the first baffle and the second baffle are respectively in contact with both ends of the motor. This is the specific setting of the limiting portion. When the motor is placed between the limiting portion and the first baffle and the second baffle, the motor is defined between the first baffle and the second baffle.

Preferably, the height of the first baffle and the second baffle is greater than half of the thickness of the motor; the motor includes a rotating shaft protruding from one end of the motor, and the first baffle is disposed There is a shaft to avoid the space. The blade is fixed on the rotating shaft of the motor, and the rotating shaft avoiding the space fixes the blade in the body outside the limiting portion.

Preferably, a first protrusion is disposed between the rotating shaft and the motor, the first protrusion is integrally disposed with the motor, and the first baffle is disposed on the first baffle The first card position. When the micro vacuum cleaner is used, the rotating shaft is to be rotated, and when the rotating shaft rotates, it will rub against the rotating shaft avoiding position on the first baffle, which will affect the rotation of the rotating shaft; and the rotating shaft and the motor are disposed close to the motor end. The first bump of the portion is disposed on the first baffle on the first baffle, and the first bump is in direct contact with the first latch, and the rotating shaft does not contact the first baffle. There is no friction between the rotating shaft and the first baffle, which does not affect the rotation of the rotating shaft, and the first lug can also serve as a limiting structure to better define the motor in the first baffle and the second baffle. The location between.

Preferably, the first protrusion is in the shape of a disk, and the width of the first protrusion is larger than the diameter of the rotating shaft and smaller than the width of the motor. This is the specific shape of the first bump, and is of course not limited to a round cake shape, but the round cake shape facilitates fixing the first bump to the first card position on the first baffle.

Preferably, the length of the first bump is greater than the thickness of the first baffle. This facilitates that the first bump will protrude from the first baffle after being fixed. When the motor needs to be disassembled, the motor can be taken out from the first baffle and the second baffle by simply holding the first bump by hand. Preferably, the opposite ends of the first bumps of the motor are provided with second bumps, and the second baffle is provided with a second latching position that is matched with the second bumps. Providing the second bump can further fix the position of the motor between the first baffle and the second baffle.

Preferably, the length of the second protrusion is greater than the thickness of the second baffle, and the second protrusion is in the shape of a disk. This is the specific structure of the second limiting portion. The second projection is arranged in a round shape, which is also convenient for holding the second projection by hand when the motor is disassembled.

Preferably, the main body includes opposite front and rear shells, and the first baffle and the second baffle are disposed on the front and rear shells, and the front shell and the rear shell are combined The first baffle and the second baffle are overlapped together. This is a specific arrangement of the first baffle and the second baffle.

Preferably, the limiting portion is a card slot disposed inside the main body and adapted to the shape of the motor, and the card slot and the motor are closely matched. This is another way of setting the limiter. The motor is fixed inside the card slot that fits the shape of the motor. The card slot completely defines the position of the motor inside the body, so that the motor is firmly fixed inside the body.

The invention is provided with a limiting portion for fixing the motor and closely matching with the motor inside the main body, so that the motor is firmly fixed in the limiting portion inside the main body, and there is no glue fixing for the glue for a long time. The motor is not firmly fixed due to poor viscosity.
