[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0028] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figure 1 As shown, a handheld vacuum cleaner gun includes a grip assembly 100, a charging base 200 at the bottom of the grip assembly 100, and a connecting seat 210 at the top of the charging base 200. The grip assembly 100 is composed of a first splicing component 110 and a second splicing component 120, which are detachably clamped to the side wall of the connecting seat 210. A first air duct 300 is detachably mounted on the top of the grip assembly 100. A connecting sleeve is detachably connected to the end of the first air duct 300 away from the grip assembly 100. A first air inlet 410 is provided on the connecting sleeve. An air outlet 310 is provided on the side of the grip assembly 100 away from the first air duct 300.

[0029] In the normal state of this application, the grip component 100 is connected to the charging base 200 by clamping. When it needs to be started, the fan inside the grip component 100 (not shown in the figure) is started, and the outside air is drawn into the connecting sleeve 400 through the first air inlet 410. After being filtered, the air enters the grip component 100 through the first air duct 300 and finally flows out through the air outlet 310.

[0030] Compared with the prior art, the grip component 100 of this application clamps the charging base 200 through the first splicing member 110 and the second splicing member 120. When it is necessary to replace the charging base 200 with a different label, it is only necessary to remove the first splicing member 110 and the second splicing member 120 from the connecting seat 210. While ensuring the reliability of the connection between the grip component 100 and the charging base 200, it can also adapt to different types of charging bases 200, and has a wider range of versatility.

[0031] Furthermore, based on the above embodiments, such as Figure 2 As shown, a first through hole 211 is provided on the connecting seat 210. The first through hole 211 is disposed opposite to each other on the side wall of the connecting seat 210. A hollow first fixing rod 111 and a second fixing rod 121 are provided on the bottom inner side of the first splicing member 110 and the second splicing member 120. The first fixing rod 111 can be inserted into the second fixing rod 121. When the first splicing member 110 and the second splicing member 120 are connected to the charging base 200, the first fixing rod 111 and the second fixing rod 121 are respectively inserted into the first through hole 211 on the side wall of the connecting seat 210, and then they are sleeved and fixed to each other in the connecting seat 210. Finally, a screw (not shown in the figure) passes through the first fixing rod 111 and the second fixing rod 121 to fix them.

[0032] Furthermore, based on the above embodiments, combined with Figure 3 and Figure 4 As shown, the grip assembly 100 includes a handle portion 130 and a receiving cavity 140. The receiving cavity 140 is used to configure a fan (not shown in the figure). The first air duct 300 and the air outlet 310 are respectively disposed on both sides of the receiving cavity 140. A connecting ring 150 is provided at one end of the receiving cavity 140 near the first air duct 300. The first air duct 300 is detachably connected to the receiving cavity 140 through the connecting ring 150.

[0033] Furthermore, based on the above embodiments, such as Figure 3As shown, the connecting ring 150 includes a ring body 151. A plurality of first slots 152 are provided along the outer ring surface of the ring body 151 at a predetermined interval. A plurality of second slots 320 that cooperate with the first slots 152 are provided on the inner wall of the first air duct 300. When it is necessary to connect the first air duct 300 to the receiving cavity 140, the first air duct 300 can be inserted into the outer ring surface of the connecting ring 150, and then the first slots 152 and the second slots 320 can be fixed by rotation to form a snap-fit, thereby fixing the first air duct 300 on the outer ring of the connecting ring 150.

[0034] Furthermore, based on the above embodiments, such as Figure 3 As shown, an air duct 330 is provided inside the first air duct 300. The air duct 330 communicates with the interior of the first air duct 300. The position of the first air inlet 410 corresponds to the air duct 330. A first filter screen 331 is provided on the air duct 330. When the fan is started, the outside air is drawn into the connecting sleeve 400 through the first air inlet 410, and after passing through the first filter screen 331 to remove impurities, it enters the first air duct 300 through the air duct 330, and finally flows out from the air outlet 310 after passing through the receiving cavity 140.

[0035] This application also employs a second method of dust collection, combined with... Figure 3 , Figure 4 and Figure 5As shown, the difference from the first embodiment is that a shaft connection is formed between the connecting sleeve 400 and the bottom of the first air duct 300, a buckle 420 is provided at the top of the connecting sleeve 400, and a fixing groove 340 that can cooperate with the buckle groove is provided on the top outer wall of the first air duct 300. In the first embodiment, one end of the connecting sleeve 400 and the first air duct 300 is connected to each other by the buckle 420 and the fixing groove 340, and the other end forms a shaft connection, so the connecting sleeve 400 and the first air duct 300 are connected to each other. In the second embodiment, by opening the buckle 420, the connecting sleeve 400 is disengaged from the first air duct 300, thereby forming a second air inlet 370 on one side of the first air duct 300. Clearly, the second air inlet 370 and its air intake area are much larger than the area of ​​the second air inlet 370, thereby increasing the air intake volume. In addition, in this embodiment, a filter disc 350 is provided inside the first air duct 300, and a threaded groove 351 is provided on the side wall of the filter disc 350. A limiting strip 360 that can cooperate with the threaded groove 351 is provided on the inner wall of the first air duct 300. Thus, the filter disc 350 can be fixed inside the first air duct 300 by tightening the threaded groove 351 onto the limiting strip 360. At this time, in this embodiment, the outside air first enters the first air duct 300 through the second air inlet 370, then is filtered by the filter disc 350, and flows out from the air outlet 310 after passing through the receiving cavity 140.

[0036] This application also provides a third method for dust collection, such as... Figure 6 As shown, the difference from the first embodiment is that a second air duct 500 is also installed on the connecting ring 150. One end of the second air duct 500 is provided with a third air inlet 510. Several fourth slots 520 are provided on the outer wall of the end of the second air duct 500 away from the third air inlet 510. Several third slots 153 are provided along the inner ring surface of the ring body 151 at predetermined intervals. When it is necessary to connect the second air duct 500 to the receiving cavity 140, the second air duct 500 can be inserted into the outer or inner surface of the connecting ring 150, and then rotated to... The third slot 153 and the fourth slot 520 form a snap-fit ​​fixation, thereby fixing the second air duct 500 on the outer ring of the connecting ring 150. When implementing this solution, the first air duct 300 and the outer surface of the connecting ring 150 are first removed, and then the second air duct 500 is fixed on the outer ring of the connecting ring 150 using the third slot 153 and the fourth slot 520. Compared with the first embodiment, the diameter of the second air duct 500 in this embodiment is significantly smaller than that of the first air duct 300, so this embodiment can extend into a smaller space to enter the dust collection.

[0037] This application also provides a third method for dust collection, such as... Figure 2As shown, a connecting plate 220 is provided at the bottom of the charging base 200. When charging is required, the charging base 200 is first connected to the grip component 100, and then the charging base 200 is inserted into the battery box, and the connecting plate 220 is connected to the battery box.

[0038] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
