DETAILED DESCRIPTION

[0015] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts are within the protection scope of the utility model.

[0016] Please refer to Figure 1-4The utility model provides the following technical solution: a portable dust collecting device, comprising a suction head 1, a dust bin, and a fan, the suction head 1 being arranged at the end of the dust bin, the fan being provided with two, namely a first fan 4 and a second fan 5, a side wall of the dust bin being provided with a first air duct 6, an end of the dust bin away from the suction head 1 being provided with a second air duct 7, the air inlet of the first fan 4 being connected to the first air duct 6, the air outlet of the first fan 4 being connected to the second air duct 7 through a third air duct 8, the air inlet of the second fan 5 being connected to the end of the second air duct 7 away from the dust bin, the first fan 4 and the second fan 5 being connected to a switch through a wire, a battery being arranged near the fan, the switch being connected to the battery through a wire, and handles 13 being provided on the outer walls of the first fan 4 and the second fan 5.

[0017] With the above structure, the first fan 4 and the second fan 5 are both used to generate negative pressure to suck the dust into the dust bin. The first fan 4 is connected to the dust bin through its air inlet and air outlet, making full use of its suction and exhaust capabilities. The second fan 5 is used to reduce the load of the first fan 4 and improve the dust collection efficiency of the entire device; this dual-fan design not only enhances the dust collection capacity, but also ensures the stable operation of the device. When any fan is damaged, the device can still be used, which is more suitable for the working environment during blasting and drilling; the handle 13 on the first fan 4 is higher than the handle 13 on the second fan 5, and the user can carry the device with both hands. The reasonable force point design makes it easier for the user to carry and use.

[0018] In this embodiment, the dust bin includes a first bin body 2 and a second bin body 3 , and the first bin body 2 is connected to the second bin body 3 via a threaded ring 9 .

[0019] In the above structure, the dust bin is divided into a first bin body 2 and a second bin body 3, which are connected by a threaded ring 9; this design makes the disassembly and cleaning of the dust bin simple and quick, and the user can easily maintain and service the device, extending its service life.

[0020] In this embodiment, a first negative pressure port 10 is provided on the outer wall of the first warehouse body 2, the first air duct 6 is connected to the first negative pressure port 10, a second negative pressure port 11 is provided at the end of the second warehouse body 3 away from the threaded ring 9, and the second air duct 7 is connected to the second negative pressure port 11; a filter 12 is provided in the first negative pressure port 10 and the second negative pressure port 11.

[0021] The above structure is adopted, which not only improves the efficiency and range of dust collection, but also makes the suction force of the fan more evenly distributed in the dust bin, thereby improving the dust collection effect; the filter 12 in the negative pressure port effectively prevents large particles of dust from entering the fan, thereby protecting the normal operation of the fan.

[0022] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
