[0002] There are many types of vacuum cleaners on the market, which are usually divided into upright, horizontal and handheld types according to usage habits. Among them, handheld vacuum cleaners have a large consumer market both at home and abroad due to their small size and flexible use. Existing handheld vacuum cleaners usually include a body and a dust cup. The body is battery-powered, and the dust cup collects the sucked dust through its suction port. Since the suction port needs to be connected to cleaning accessories such as floor brushes, a conductive structure needs to be provided at the suction port to power accessories such as floor brushes. The most common existing conductive structure is the combination of pins and sockets. When assembling the suction port, it is necessary to consider making way for the conductive structure. Multiple parts are often required for assembly, which is time-consuming and labor-intensive, and the production cost is relatively high. Utility Model Content

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] As Figure 1 shown, a handheld vacuum cleaner includes a handheld body assembly 1 and a dust cup assembly 2. For the convenience of cleaning, the dust cup assembly 2 is detachably connected to the front side of the handheld body assembly 1. The front end of the dust cup assembly 2 is provided with a suction port, and the suction port can be connected to cleaning accessories, such as a floor brush, a flat suction, etc. The handheld body assembly 1 is also detachably provided with a battery pack 4. In addition to supplying power to the motor inside the handheld body assembly, the battery pack 4 also needs to supply power to some cleaning accessories, such as a floor brush with a roller brush. Generally, the roller brush motor needs to be powered by the battery pack. Therefore, a conductive structure is usually provided at the suction port.

[0018] As Figures 2 - 6A conductive needle assembly structure at the position of the suction nozzle seat of a vacuum cleaner as shown, includes a suction nozzle seat 21 at the front end of the dust cup assembly 2 and a suction nozzle seat cover 3. The suction nozzle seat 21 and the dust cup assembly 2 are integrally injection-molded. The suction nozzle seat cover 3 is assembled outside the suction nozzle seat 21 and covers it. The suction nozzle seat cover 3 and the suction nozzle seat 21 are connected by a snap-fit method. This connection method is relatively common and will not be elaborated here. A conductive spring needle 5 is provided inside the suction nozzle seat 21. The conductive spring needle 5 is provided with a telescopic spring needle head 51. The conductive spring needle 5 is a component directly purchased on the market. The conductive spring needle 5 can be used for conduction and has a telescopic contact head by itself. The conductive spring needle 5 includes two positive and negative poles, and is symmetrically arranged on one side close to the dust cup assembly 2. In this embodiment, positioning posts 211 are provided inside the suction nozzle seat 21, and positioning holes 52 are provided on the conductive spring needle 5. The conductive spring needle 5 is fixed to the positioning posts 211 through the positioning holes 52, so that the conductive spring needle 5 is reliably fixed inside the suction nozzle seat 21. The suction nozzle seat cover 3 forms a snap-fit end 31, and a spring needle hole 311 corresponding to the spring needle head 51 is opened on the upper surface of the snap-fit end 31. After the suction nozzle seat cover 3 is assembled, the spring needle head 51 can telescopically move in the spring needle hole 311. As Figure 4 shown, when the dust cup assembly 2 is separated from the handheld body assembly 1, at this time, the spring needle head 51 protrudes from the spring needle hole 311; a contact end in contact with the handheld body assembly 1 is formed at the upper end of the dust cup assembly 2. A conductive sheet 6 is provided at the lower edge of the handheld body assembly 1. The conductive sheet 6 also includes two positive and negative poles, which are respectively arranged corresponding to the positive and negative conductive spring needles. The end of the conductive sheet 6 is embedded in the handheld body assembly 1 and is connected to the control circuit board (not shown in the figure) through this end. The control circuit board controls the battery pack 4 and the conductive sheet 6 to form electrical conduction. As Figure 6 shown, when the dust cup assembly 2 is connected to the handheld body assembly 1, at this time, the spring needle head 51 is compressed and forms a conductive connection with the conductive sheet 6.

[0019] Furthermore, the suction nozzle seat 21 is also provided with a conductive connection end (not shown in the figure) for connecting the floor brush accessory. The conductive connection end is connected to the conductive spring needle 5 through a wire 7. Thus, after the dust cup assembly 2 is connected to the handheld body assembly 1, the battery pack 4 can supply power to the connected floor brush accessory.

[0020] Furthermore, the suction nozzle seat cover 3 is integrally formed. When the suction nozzle seat cover 3 is sleeved and assembled into the suction nozzle seat 21 from the outside to the inside, the spring needle head 51 will interfere with the snap-fit end 31. Since the spring needle head 51 is telescopic, only by using a tool to press down the spring needle head 51 and then continue the assembly until the spring needle head 51 moves into the spring needle hole 311, and then the suction nozzle seat cover 3 and the suction nozzle seat 21 are snap-fitted and fixed, the assembly can be completed, which saves time and effort and effectively improves the assembly efficiency.

[0021] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
