Wherein, the air jets 641 can be set as shown in Figures 5 and 6 in which one air jet 641 is arranged at the center of the circle, and the other air jets 641 are arranged in a double ring shape, but it can also be only set in a single ring shape. The total number of jet ports 641 can also be determined according to actual needs, and is not limited thereto.

In this way, the second embodiment can also achieve the same purpose and effect as the above-mentioned first embodiment, and by providing a plurality of air jets 641, a more uniform and comprehensive dust removal and cleaning effect can be achieved.

Referring to Figures 7, 8 and 9, it is a third embodiment of the new pen-type dust removal device. The third embodiment is similar to the first embodiment, and the third embodiment is similar to the first embodiment. The difference is:

The end of the jet rod 64 defines two jet ports 641.

The base 6 also includes a rotating member 66 rotatably arranged at the end of the air jet rod 64. Wherein, the rotating member 66 is configured to limit the rotating member 66 up and down by using two upper and lower clamp members 67 embedded at the end of the air-jet rod 64. However, other limiting methods that can allow rotating motion can also be used, and this is not a limitation. .

The rotating member 66 defines a rotating flow channel 661 connected to the air jets 641. The rotating flow channel 661 forms two side air ports 662 on the sides of the rotating member 66 and two air ports 663 below the bottom surface of the rotating member 66. And there is an airflow portion 664 of radiation that intersects the rotation axis of the rotating member 66 in two extending directions, and a communicating portion 665 that communicates the air jets 641 and the airflow portions 664, and the airflow portions 664 rotate in the rotation The openings on the sides of the member 66 are the side air ports 662.

In this embodiment, the rotating flow channel 661 forms two point-symmetrical side air ports 662, and forms two symmetrical lower air ports 663 and two point-symmetrical airflow portions 664. However, the rotating flow channel 661 can also form only a single side air port 662, and form a single lower air port 663 and a single air flow portion 664, or form more than three mutually matched side air ports 662, lower air ports 663 and air flow portions. 664, not limited to this.

Thereby, after the gas is ejected from the air jet ports 641, it will be ejected from the side air ports 662 and the lower air ports 663 through the communicating portion 665 and the air flow portions 664, and when the air flow is ejected from the side air ports 662 (As shown by the hollow arrows in Figures 8 and 9), because the ejection direction intersects the radiation of the rotation axis of the rotating member 66, it will drive the rotating member 66 to rotate around its own axis to generate a rotating jet of air flow .

In this way, the third embodiment can also achieve the same purposes and effects as the first embodiment, and by providing the rotating member 66 and the airflow parts 664, a rotating jet airflow can be provided to achieve a better dust removal and cleaning effect. .

In summary, the new pen-type dust removal device and its nozzle unit can indeed achieve the purpose of new cost.

However, the above-mentioned are only examples of the present model, and should not be used to limit the scope of implementation of the present model, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
