The present invention relates to a vacuum cleaner having an air injection function, and more specifically, to install an air injection pipe for injecting compressed air supplied from a compressor in a suction pipe to easily clean foreign matters or aggregated foreign matters in the corners. It relates to a vacuum cleaner having an air injection function that can be.

In general, a vacuum cleaner generates a vacuum inside a suction motor, and is configured to suck foreign substances such as dust from the outside through a pipe. It is applied to various fields. Among such vacuum cleaners, a technique for using compressed air has been proposed as a method for conveniently cleaning the corners or for easily treating the dusts.

Republic of Korea Utility Model Publication No. 1989-0006592 "Vacuum cleaner air injector" is a vacuum cleaner, in which a fixed plate and a ventilation control plate is installed inside the ventilation hole of the body and the air inlet is installed at the bottom of the opening and closing the suction pipe There is a suction hole and a spray hole formed in the lower part of the body to connect the air injection pipe to the injection hole and the air inlet to rotate the external adjustment knob, the ventilation control plate is slid from one side of the fixed plate to suck or spray air It proposes an air jet of the vacuum cleaner, characterized in that configured to be made.

Republic of Korea Utility Model Publication No. No.1990-0007527 "Vacuum cleaner combined with air filling" is to install a static and revolution rotating motor with a conventional fan inside the body and a front case for easy insertion and removal. It is proposed an air-filled vacuum cleaner by drilling guide grooves on both side walls of the tip opening of the case and installing a slide plate having an air outlet pipe.

Republic of Korea Utility Model Publication No. 95-428 "Vacuum suction and spray combined vacuum cleaner" is a combined suction and vacuum cleaner and air injector vacuum cleaner with a built-in compressor, the suction and power of the vacuum cleaner With a motor, a compressor power transmission device, and an air compression tank and an air device, it is proposed a vacuum suction combined use vacuum cleaner that can inhale dust at the same time as air spraying.

However, such a conventional vacuum cleaner has a problem in that it is simply configured to install a compressor to inject compressed air, or is configured to eject air by rotating the suction motor installed in the vacuum cleaner in a reverse direction, which does not substantially increase the cleaning effect. That is, according to the prior art, it is possible to blow the dust in the corners by blowing compressed air or to separate the agglomerated dust, but the dust or foreign matters are scattered in the air, which is accompanied by the difficulty of cleaning.

Therefore, the present invention has been proposed in view of the above, and an object of the present invention is to provide a vacuum cleaner having a new type of air injection function that can solve the problems of the prior art and increase the cleaning effect.

In particular, the present invention provides a vacuum cleaner having a new type of air jetting function that can easily clean the foreign matter and the condensed matter in the corner by installing an air injection pipe for injecting compressed air supplied from the compressor in the suction pipe. It aims to provide.

In addition, the present invention is to provide a vacuum cleaner having a new type of air injection function that can increase the use efficiency of the filter by preventing the foreign matter sucked into the vacuum cleaner by the suction pump to agglomerate on one side of the filter. It is done.

According to a feature of the present invention for achieving the above object, the present invention and the main body 20 is installed therein suction motor 30; It is connected to the main body 20, the suction opening 42 is formed at the end so that foreign matter is sucked into the main body 20 through the suction opening 42 by the operation of the suction motor 30. A suction pipe 40; The nozzle 62 is inserted into the suction pipe 40 so that the nozzle 62 is located in the suction pipe 40 in proximity to the suction opening 42, and is connected to the compressor 70 to be supplied from the compressor 70. It includes an air injection pipe 60 to allow air to be injected through the nozzle 62.

In such a vacuum cleaner having an air injection function according to the present invention, the air injection pipe 60 is provided with an air valve 64 for turning on / off the supply of air supplied from the compressor 70, the suction pipe The handle 50 is coupled to the 40, and the handle 50 may be provided with a switch 66 for turning on / off the air valve 64.

In the vacuum cleaner having an air injection function according to the present invention as described above, the body 20 is further provided with a foreign matter collector 32 to which the discharge opening 44 of the suction pipe 40 is connected, and the foreign substance collector 32 ) Vortex (80, 80 ', 80 ") is coupled to be located below the discharge opening 44 of the suction pipe 40 to be formed to hit the air sucked through the discharge opening 44 More can be installed.

1 is a view for explaining the technical idea of a vacuum cleaner having an air injection function according to the present invention.

Referring to Figure 1, the vacuum cleaner 10 having an air spraying function according to the present invention is characterized in that the inlet pipe 40 is installed in the suction pipe 40 to inhale the foreign material at the same time as the injection of the air do. That is, the conventional vacuum cleaner is usually configured to only have a suction function, or to separate the suction and air injection, but the vacuum cleaner 10 according to the present invention is compressed air by allowing the air injection pipe 60 is installed in the suction pipe 40 At the same time that the injection is to be sucked back into the interior through the suction pipe (40).

The vacuum cleaner 10 according to the present invention basically includes a main body 20, a suction pipe 40, and an air injection pipe 60. The main body 20 has a suction motor 30 installed therein to form a body, and a general vacuum cleaner may be applied.
