[0024] Embodiment: As Figure 1-2 shown, the present invention discloses a first embodiment of a conductive component 140, which includes: a conductive member 142, a fixing member 144 that at least partially houses the conductive member 142 and allows the conductive member 142 to move relatively, and an elastic member 146 disposed between the conductive member 142 and the fixing member 144 and covered by the conductive member 142 or the fixing member 144. The conductive member 142, the fixing member 144, and the elastic member 146 are all made of conductive materials, and more preferably metal materials. The elastic member 146 is preferably a spring. The conductive component is an automated assembly component, which does not require human intervention, can improve the assembly efficiency, has high precision, and a long service life.

[0025] The conductive member 142 includes a head 1420, a tail 1424, and an intermediate portion 1422 located between the head 1420 and the tail 1424. The diameter of the head 1420 is larger than the diameter of the tail 1424 and smaller than the diameter of the intermediate portion 1422. The tail 1424 is sleeved with the elastic member 146.

[0026] The fixing member 144 includes a fixing front end 1440, a receiving cavity 1442 located inside the fixing front end 1440 and housing the intermediate portion 1422 and the elastic member 146, and a welding end 1444 that is integrally connected to one end of the fixing front end 1440 and welded to the circuit board at the other end. The fixing front end 1440 is provided with a riveting portion 1443 that can be in electrical contact with the head 1420. The riveting portion 1443 allows the head 1420 to be exposed and prevents the intermediate portion 1422 from detaching from the receiving cavity 1442. To further ensure the electrical conductivity, one end of the elastic member 146 remains in electrical contact with the fixing front end 1440. Moreover, the elastic member 146 is located inside the receiving cavity 1442, is not affected by the outside, and does not require manual assembly, with high assembly efficiency.

[0027] As Figure 3As shown, the present invention discloses a second embodiment of a conductive component 340, which includes: a conductive member 342, a fixing member 344 that at least partially houses the conductive member 342 and allows the conductive member 342 to move relatively, and an elastic member 346 disposed between the conductive member 342 and the fixing member 344 and jointly covered by the conductive member 342 and the fixing member 344. The conductive member 342, the fixing member 344, and the elastic member 346 are all made of conductive materials, more preferably metal materials, and the elastic member 146 is preferably a spring. The conductive component is an automated assembly component, which does not require human intervention, can improve the assembly efficiency, has high precision, and a long service life.

[0028] The conductive member 342 includes a head 3420, a tail 3422, and a receiving portion 3424 located between the head 3420 and the tail 3422 and at least receiving one end of the elastic member 346. The diameter of the head 3420 is greater than the diameter of the receiving portion 3424 and less than the diameter of the tail 3422. Since the receiving portion 3424 occupies most of the space of the conductive member 342, it can save material costs and the process is simpler.

[0029] The fixing member 344 is the same as the fixing member 144 in the first embodiment. It includes a fixing front end 3440, a receiving cavity 3442 located inside the fixing front end 3440 and housing the tail 3422 and the elastic member 346, and a welding end 3444 with one end integrally connected to the fixing front end 3440 and the other end welded to the circuit board. The fixing front end 3440 is provided with a riveting portion 3443 that can be in electrical contact with the head 3420. The riveting portion 3443 allows the head 3420 to be exposed and prevents the tail 3422 from detaching from the receiving cavity 3442. The other end of the elastic member 346 remains in electrical contact with the inner wall of the fixing front end 1440. Moreover, the elastic member 346 is located inside the receiving portion 3424 and the receiving cavity 3442, is not affected by the outside, and does not require manual assembly, so the assembly efficiency is high.

[0030] As Figures 4-8 shown, the present invention discloses a third embodiment of a vacuum cleaner, which includes a body 100, a dust cup 200 detachably fitted to the body 100, a motor 300 disposed inside the body 100, a power supply 400 that provides power to the motor 300 and is detachable, and a vacuum cleaner accessory 500 connected to the dust cup 200. The vacuum cleaner accessory 500 is a conductive telescopic tube in this embodiment, and can also be an electric floor brush or other electric accessories. The power supply 400 is a DC power supply such as a lithium battery or a nickel-metal hydride battery.

[0031] The body 100 includes a support portion 110, a grip portion 120 spaced apart from the support portion 110, and a connecting portion 130 connecting the bottoms of the support portion 110 and the grip portion 120. A contact surface 112 for supporting the dust cup 200 is provided at the top of the support portion 110. The contact surface 112 is preferably an arc surface to cooperate with the cylindrical dust cup. The conductive component 140 is located above the contact surface 112 and on one side of the air inlet end of the motor 300, and the number thereof is three, and is welded to the circuit board 150, while the circuit board 150 is snap-fixed by a pair of locking arms 162 of the fixing frame 160.

[0032] The dust cup 200 includes an air inlet 202 at one end, an air outlet 204 at the other end, a contact terminal 210 adjacent to the air outlet 204, a conductive terminal 220 adjacent to the air inlet, a cyclone air inlet assembly 230 therein, a cyclone air outlet assembly 240 connected to the cyclone air inlet assembly 230, and a filter element 250 downstream of the cyclone air outlet assembly 240. The cyclone air inlet assembly 230 is provided with a wire channel 232, and the contact terminal 210 and the conductive terminal 220 are connected by a wire 234. The wire 234 at least partially passes through the wire channel 232 and is independent of the cyclone air inlet channel.

[0033] The contact terminal 210 includes a contact portion 212, a first side portion 214 bent on one side of the contact portion 212, and a second side portion 216 bent on the other side of the contact portion 212. One end of the second side portion 216 is formed with an inverted buckle 218, and the other end is formed with a welding hole 219. There are also inverted buckles 218 inside the first side portion 214. The two inverted buckles 218 are oppositely arranged and are used to be embedded into the dust cup 200.

[0034] During operation, the head 1420 of the conductive member 142 abuts against the contact portion 212 under the action of the elastic member 146. Thus, the current of the power supply 400 passes through the circuit board 150, the fixing member 144, the conductive member 142, then through the contact portion 212 and the welding hole 219 of the contact terminal 210, and then is transmitted to the conductive terminal 220 through the wire 234, and finally transmitted to the vacuum cleaner accessory 500.

[0035] The advantages of the present invention are: realizing elastic contact between the conductive component and the contact terminal, and the conductive component is an automatic assembly component, which is small in size, does not require human intervention, can improve the assembly efficiency and has high precision and long service life.

[0036] Various modifications to these embodiments will be apparent to those of ordinary skill in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the invention. Thus, the invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
