Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to an anti-static vacuum cleaner. Background Technology

[0002] Handheld vacuum cleaners are popular due to their lightweight and flexible design. They can be used with various cleaning attachments to clean floors, furniture, and walls. Users can usually perform these operations by holding the device with one hand. However, the high-speed movement of dust inside the vacuum cleaner during operation can generate static electricity on its surface. If too much static electricity accumulates, users may experience hand injuries when touching the device. To avoid this, existing handheld devices typically add a metal conductive plate or ring to the handle grip area and then release static electricity through a grounding connection. This method requires a conductive plate mounting structure on the handle or the conductive ring to be integrally molded with the handle during injection molding. This not only increases the manufacturing difficulty but also the production cost, thus reducing the overall competitiveness of the product. Utility Model Content

[0003] The purpose of this invention is to provide an antistatic vacuum cleaner to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An antistatic vacuum cleaner includes a main body, a dust cup detachably mounted on the front side of the main body, a vacuum device built into the upper rear side of the main body, and a battery pack detachably mounted on the lower rear side of the main body. A handle is formed between the vacuum device and the battery pack. A main switch is movably connected to the inside of the handle. An opening groove is formed on the pressing surface of the main switch. A conductive element is provided inside the main switch. The front end of the conductive element is installed in the opening groove and is accessible. The rear end of the conductive element is abutted against the inside of the main body by a spring. The tail end of the spring is connected to the negative terminal of the battery pack by a wire. A micro switch is also installed inside the handle. A corresponding drive end for the micro switch is formed on the lower rear side of the main switch. The micro switch is electrically connected to a circuit board.

[0006] Preferably, the handle forms a horizontal boss at the lower end face of the main switch, and the connection between the handle and the main body also forms a horizontal limit on the upper end face of the main switch.

[0007] Preferably, an air duct is formed inside the handle, and the air duct is connected to the vacuum pump and the battery pack respectively.

[0008] Preferably, the front end of the lower rear side of the main body forms a square end cap, and the rear end of the lower rear side of the main body has a tail end adapted to the curvature of the handle, wherein the arc of the tail end includes at least a portion of straight lines.

[0009] Preferably, a locking groove is formed at the bottom of the square end cap, and the battery pack is provided with a corresponding latch and a latch button.

[0010] Preferably, the dust cup and the vacuum pump are arranged horizontally and coaxially.

[0011] This invention improves user experience by incorporating a conductive component on the main switch, which allows static electricity to be conducted to the negative terminal of the battery pack and released when the main switch is pressed, thus preventing hand injuries. The curved tail end of the main body is designed with a partial straight section, increasing the contact points between the tail end and the placement surface, making the main body more stable when placed horizontally.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4The illustrated antistatic vacuum cleaner includes a main body 1. A dust cup 2 is detachably mounted on the front side of the main body 1. A vacuum device 3 is built into the upper rear side of the main body 1. The vacuum device 3 can be a motor or a fan. The vacuum suction generated by the vacuum device 3 draws dust-laden air into the dust cup 2. The filtered clean air is discharged by the vacuum device 3, while the dust particles are collected in the dust cup 2. In this embodiment, the dust cup 2 and the vacuum device 3 are arranged horizontally and coaxially, which minimizes the airflow path and reduces suction loss. A battery pack 4 is detachably mounted on the lower rear side of the main body 1. The battery pack 4 powers the vacuum device 3. A handle 5 is formed between the vacuum device 3 and the battery pack 4. A main switch 6 is movably connected to the inner side of the handle 5. Pressing the main switch 6 starts the operation. The pressing surface of the main switch 6... An opening groove 61 is formed. The main switch 6 has a conductive element 7 inside. The conductive element 7 is made of metal. The front end of the conductive element 7 is installed in the opening groove 61 and can be touched. The rear end of the conductive element 7 is supported by the main body 1 through a spring 8. The tail end of the spring 8 is connected to the negative terminal of the battery pack 4 through a wire (not shown in the figure). A micro switch 9 is also installed inside the handle 5. The lower rear end of the main switch 6 forms a corresponding drive end 62 of the micro switch 9. The micro switch 9 is electrically connected to the circuit board 10 located inside the main body 1. This arrangement allows the user to touch the conductive element 7 when pressing the main switch 6, thereby conducting the static electricity carried to the negative terminal of the battery pack 4 for release. At the same time as pressing the main switch 6, the micro switch 9 is triggered. After receiving the signal from the micro switch 9, the circuit board 10 controls the vacuum device 3 to start and start the dust collection operation.

[0021] Furthermore, a horizontal boss 51 is formed on the lower end face of the handle 5 at the main switch 6, and the connection between the handle 5 and the main body 1 also forms a horizontal limit on the upper end face of the main switch 6, so that the main switch 6 is restricted from pressing in the horizontal direction after it is installed on the handle 5.

[0022] Furthermore, an air duct 52 is formed inside the handle 5. The air duct 52 is connected to the vacuum device 3 and the battery pack 4 respectively. The air duct 52 recovers part of the clean airflow discharged through the vacuum device 3 and brings it to the surface of the battery pack 4 to dissipate heat.

[0023] Furthermore, such as Figure 5-7 As shown, a square end cap 11 is formed at the lower rear end of the main body 1. The shape of the square end cap 11 is adapted to the upper part of the battery pack 4, and it is easy to place the main body 1 stably after the battery pack 4 is removed. The lower rear end of the main body 1 has a tail end 12 adapted to the curvature of the handle 5. The tail end curve includes at least a part of a straight line segment 121. When the main body 1 after removing the battery pack 4 is placed on a horizontal surface, the straight line segment 121 is in full contact with the horizontal surface, and the support for the tail end 12 is more stable than a single point contact.

[0024] Furthermore, a locking groove 111 is formed at the bottom of the square end cap 11, and the battery pack 4 is provided with a latch 41 and a latch button 42. The latch 41 is locked to the inside of the locking groove 111 by a snap-fit ​​connection, and is unlocked by the latch button 42, so that the battery pack 4 is separated from the main body 1. The snap-fit ​​connection is a mechanical connection method commonly used in the field, which will not be described in detail here. A ventilation opening 43 for connecting the air duct 52 is also formed on the upper surface of the battery pack 4.

[0025] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
