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, handheld computers and so on. When the computer is in use, dust or other impurities in the air can easily enter the keyboard, chassis or display. Dust Uncleaning for a long time can 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. Just plug the data cable plug directly into the data cable interface and use it. No other power supply is needed. The motor is glued inside the main body and corresponds to the main body. The air inlet port is provided at the position of the blade, so that the rotation of the surrounding air can be driven when the motor drives the blade to rotate, thereby forming a required negative pressure environment. This program is not public. However, the suction head is provided with a plurality of suction holes which are outwardly convex, and the dust collection efficiency is low, so that when the dust on the keyboard is removed, it takes a long time to complete, which is time consuming.

[Summary of the Invention]

The technical problem to be solved by the present invention is to provide a micro vacuum cleaner with high dust suction efficiency.

The object of the present invention is achieved by the following technical solutions: a micro vacuum cleaner comprising a suction head, wherein the suction head is provided with at least two outwardly protruding suction holes, and the suction head is further provided with a suction nozzle Suction hole Use a matching brush.

Preferably, one side of the suction hole is provided with a plurality of brush insertion holes which are uniformly distributed, and the brush is inserted and fixed in the brush insertion hole. This is the specific way to fix the brush on the tip. Set the brush implant hole to fix the brush in the brush implant hole. Just fill the brush implant hole when fixing the brush. It does not fall off the brush insertion hole during normal use.

Preferably, the brush implantation hole and the suction hole are parallel to each other. In this way, the suction holes and the brushes are parallel to each other.

Preferably, the inside of the suction head is provided with a brush limiting portion that cooperates with the brush implantation hole, the brush limiting portion has a gap with the inner wall of the suction head and the suction A raised surface that completely conforms to the inner wall of the head. Setting the brush limiter can limit the distance that the brush is inserted into the inside of the tip when fixing the brush, so as to avoid the jaggedness of the brush.

Preferably, the width of the brush limiting portion is greater than or equal to the total width of the brush implantation hole. This ensures that the brush limiter can limit all the brushes installed on the tip.

Preferably, the brush is fixed on the brush limiting portion with glue. When assembling the brush, the glue is dripped in the brush limit portion, and then the brush is immediately inserted into the brush limit portion through the brush insertion hole, which can further prevent the brush from being implanted from the brush during use. The hole is detached.

Preferably, the end of the suction hole is provided with a slit inclined to one side. By setting the inclined slit, the contact area between the suction hole and the keyboard can be increased, and the dust collecting efficiency of the micro vacuum cleaner can be further improved.

Preferably, the brush implantation hole is located above a longer side of the suction hole. When the user uses the micro vacuum cleaner, the longer side of the suction hole is placed on the shorter side of the front suction hole, and the brush insertion hole is placed above the suction hole. In use, the brush is used. It will be located in front of the longer side of the suction hole, and the brush can achieve the maximum dust sweeping effect.

Preferably, the micro-suction device further includes a main body provided with a blade and a main body for driving the blade, wherein the main body and the suction head are in communication; the main body is hollow and one end is provided with an opening, the suction head The open end has the same shape as the open end of the main body, and the open end of the tip is provided with an insertion portion having an outer diameter equal to the inner diameter of the open end of the main body, and the suction head is inserted and fixed on the main body. Insert the tip The attachment is fixed to the main body, and the suction head can be removed from the main body when it is necessary to remove dust inside the suction head. Preferably, the tip gradually increases in width from the set end of the suction hole to the open end, and the height from the set end of the suction hole to the end of the opening gradually increases. This is advantageous for driving the air or dust outside the suction head to the inside of the main body, thereby further improving the dust suction effect of the micro vacuum cleaner.

In the present invention, since the micro-vacuum device is provided with a brush for use with the suction hole and the brush, the dust can be sucked while using the vacuum cleaner, and the dust on the keyboard is removed by the brush, compared to the micro vacuum cleaner provided only with the suction hole. , the efficiency of vacuuming has been improved.
