Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum cleaners and relates to an anti-static structure of a handle and a handheld vacuum cleaner. Background Art

[0002] In today's society, handheld vacuum cleaners are widely popular for their convenience and efficiency. The battery packs in handheld vacuum cleaners are typically equipped with over-temperature protection. To cool the battery pack, a cooling air duct is designed into the handle of the handheld vacuum cleaner to lower the temperature of the battery pack by blowing cool air.

[0003] However, the presence of the cooling duct introduces new challenges. When using a handheld vacuum cleaner, air flows through the cooling duct, and friction between the airflow and the duct generates static electricity. This static electricity poses a significant risk of damaging electronic components, potentially reducing the performance and lifespan of the vacuum cleaner.

[0004] To address this issue, a common approach is to design the handle of a handheld vacuum cleaner into two parts: a main handle and a cover. Conductive metal parts are pre-installed on the cover, electrically connected to the circuit, and then the cover is mounted on the main handle. This method can effectively discharge static electricity to a certain extent and is relatively easy to assemble. However, the split handle design also has significant shortcomings, significantly affecting the product's aesthetics and failing to meet people's demand for high-quality cleaning tools. The integrated handle design of handheld vacuum cleaners currently has problems with the conductive metal parts being difficult to install, and the anti-static connection to the circuit is difficult, failing to resolve the static discharge issue.

[0005] Therefore, it is necessary to improve the existing technology to overcome the defects in the existing technology. Utility Model Content

[0037] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0039] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention. Example

[0040] See also Figure 3-Figure 7 As shown, a handle anti-static structure is mainly used in handheld vacuum cleaners. Specifically, it is set on the integrated handle 1 of the handheld vacuum cleaner. The handle 1 is provided with a cooling air duct 2 for cooling the battery pack of the vacuum cleaner.

[0041] The handle's anti-static structure includes a slot 11 on the upper surface of handle 1, located near the battery pack. When a person grips handle 1, the wrist aligns with slot 11. A metal half-ring 4 fits within slot 11. When a person grips handle 1, the outer surface of the metal half-ring 4 contacts the wrist, ensuring optimal contact between the metal half-ring 4 and the body, facilitating static electricity conduction.

[0042] When the metal half-ring 4 is installed in the slot 11, one side of the metal half-ring 4 penetrates the cooling air duct 2, and the raised portion 41 on the metal half-ring 4 is exposed outside the cooling air duct 2. The raised portion 41 exposed outside the cooling air duct 2 is provided with an electrostatic mounting hole 42. The electrostatic mounting hole 42 can be connected to the circuit board in the handheld vacuum cleaner via an electrostatic wire, thereby transmitting static electricity generated in the handheld vacuum cleaner to the human body for discharge.

[0043] In this embodiment, by selecting the position of the slot 11 and applying the metal half ring 4, the metal half ring 4 is installed on the handle 1 in a plug-in manner, providing installation space for the installation of the electrostatic wire, thereby solving the problem of electrostatic discharge while maintaining the integrated design of the handheld vacuum cleaner handle.

[0044] Specifically, slot 11 is a flat, semicircular recess. This unique shape not only allows for seamless integration with the handle, but also provides ample space for the installation of metal half-ring 4. Metal half-ring 4 is also flat, and when installed into slot 11, its outer contour is flush with the upper end surface of handle 1, seamlessly blending into the overall appearance of the handle without detracting from its aesthetic appeal.

[0045] When a person grips handle 1, metal half-ring 4 effectively conducts away static electricity. This is due to its excellent electrical conductivity and close contact with the wrist. Furthermore, due to its rational design, the static electricity conduction process does not cause any discomfort or discomfort to the user.

[0046] In this embodiment, the outer wall of the cooling air duct 2 of the handheld vacuum cleaner is provided with a landing 21 corresponding to the slot 11. This landing provides a stable support for the metal half-ring 4. Furthermore, a notch 22 is provided on one side of the cooling air duct 2 for the protrusion 41 to insert into, and the notch 22 communicates with the landing 21. When the metal half-ring 4 is properly installed in the slot 11, the lower end surface of the metal half-ring 4 rests on the landing 21. This design ensures a more secure installation of the metal half-ring on the handle 1.

[0047] Specifically, the metal half-ring 4 has small protrusions 43, located on either side of the metal half-ring 4, along with the raised portion 41. Once the metal half-ring 4 is properly installed in the slot 11, the small protrusions 43 are exposed outside the bonding platform 21. The combined use of the small protrusions 43 and the raised portion 41 secures and supports the metal half-ring 4 from different positions. During use, these small protrusions 43 effectively prevent the metal half-ring 4 from shaking, ensuring the stability of electrostatic conduction and ensuring that static electricity is continuously and effectively conducted away, thus preventing damage to the electronic components within the vacuum cleaner.

[0048] In this embodiment, the slots 11 are arranged in two different configurations. One is horizontal, and the other is tilted downward from the outside inward. These two configurations ensure that the metal half-ring 4 placed on the handle is either horizontal or tilted downward, respectively. This design is of great significance. When the metal half-ring 4 is in either of these two configurations, it can better integrate with the handle, improving its stability on the handle 1. Whether it is subjected to slight vibrations during daily use or various movements during operation, the metal half-ring remains firmly fixed on the handle, ensuring stable electrostatic conduction.

[0049] In this embodiment, the area of ​​the cooling air duct in the cooling air duct tube 2 covered by the metal half-ring 4 is less than 1 / 3 of the cooling air duct. In actual application, this design has been carefully considered. On the one hand, the smaller the cooling air duct occupied by the metal half-ring, the better. Because this can minimize the obstruction to the cooling air blow, ensure that the airflow in the cooling air duct can flow smoothly, thereby avoiding affecting the heat dissipation effect of the battery pack. After all, good heat dissipation of the battery pack is crucial to the normal operation and service life of the handheld vacuum cleaner. On the other hand, when determining the proportion of the metal half-ring covering the cooling air duct, the rigidity and cost of the metal half-ring also need to be comprehensively considered. If the size of the metal half-ring is excessively reduced in order to reduce the obstruction to the cooling air duct, its rigidity may be affected, making it easy to deform during use, thereby affecting the effect of electrostatic conduction. At the same time, cost is also an important factor. It is necessary to optimize the cost while ensuring performance.

[0050] Combine Figure 1 、 Figure 2 、 Figure 8 As shown, a handheld vacuum cleaner comprises a handle 1, a main housing 5, a blower assembly, a dust collection assembly 7, and a battery pack 6. The blower assembly is housed within the main housing 5, and the blower therein blows air into the cooling air duct within the handle 1. This allows airflow through the cooling air duct, effectively dissipating heat from the battery pack 6, ensuring that the battery pack remains within a suitable temperature range during operation and extending its service life. The handle 1 features a specially designed anti-static structure that dissipates static electricity without affecting the overall aesthetics and functionality of the handheld vacuum cleaner. The battery pack 6 includes a battery pack mounting seat 61 at the lower end of the handle 1. This mounting seat is equipped with a mesh 611 that corresponds to the cooling air duct 2, providing a protective shield without obstructing airflow. The battery pack is mounted at the lower end of the battery pack mounting seat 61, and the bottom of the battery pack has cooling holes, further enhancing heat dissipation. The airflow from the cooling air duct 2 directly dissipates heat from the battery pack, ensuring that the battery pack temperature does not rise excessively during operation and ensuring stable operation of the handheld vacuum cleaner.

[0051] In this embodiment, a circuit board 3 is mounted on the upper end of the battery pack mounting base 61. The circuit board 3 is electrically connected to the electrostatic mounting hole 42 via an electrostatic conductor, ensuring that static electricity can be effectively conducted away. The raised portion 41 is exposed within the gap between the circuit board 3 and the cooling air duct 2. This design provides ample clearance for the electrostatic conductor. This ensures the convenience and stability of the electrostatic conductor connection while preventing the presence of the electrostatic conductor from affecting the normal operation of other components. This makes the overall structure of the handheld vacuum cleaner more rational and efficient, improving the product's reliability and practicality.

[0052] The product of this embodiment utilizes an integrated handle design, which not only ensures the product's aesthetics but also makes the handheld vacuum cleaner more concise and streamlined in appearance, elevating the overall quality of the product. Furthermore, this design does not in any way compromise its functionality, satisfying user needs in terms of both ease of operation and vacuuming effectiveness. The metal half-ring 4 is also carefully designed for installation, being installed as a plug-in on the handle 1. This is both simple and convenient, while ensuring structural stability. Furthermore, this installation method does not detract from the overall appearance of the handle, achieving a perfect combination of aesthetics and practicality.
