Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, specifically, it relates to a portable handheld vacuum cleaner. Background Technology

[0002] With the fast pace of modern life, people's demand for home cleaning is increasing. Although traditional upright or canister vacuum cleaners have good cleaning effects, they are large and heavy, which is not convenient for quickly cleaning small areas or for situations that require frequent movement. In addition, with the increase in the number of pets in the family and the increased demand for car interior cleaning, there is a demand in the market for lightweight and efficient cleaning tools such as handheld vacuum cleaners.

[0003] Chinese utility model patent CN221383416U discloses a handheld vacuum cleaner, including a main body with a dust collection bin. The dust collection bin has a suction inlet at its front end and a cyclone filter inside, arranged along the central axis of the dust collection bin. A HEPA filter is located above the dust collection bin inside the main body, and a motor and battery pack are arranged sequentially behind the HEPA filter inside the main body. This vacuum cleaner design optimizes the overall center of gravity by eccentrically positioning the HEPA filter and dust collection bin. However, it still has certain limitations in use. While the eccentric positioning and front-mounted motor optimize the overall layout, the internal structure still requires a relatively wide outer shell to accommodate all necessary components, resulting in a still large overall size. This large size makes the vacuum cleaner inconvenient to use and store in small spaces, especially in confined environments such as car interiors. Furthermore, the large size can easily affect the user's grip comfort during prolonged use. Utility Model Content

The placement seat 2 is fixed to the bottom of the grip rod 1, serving as the container for the vacuum cleaner during use. The locking block 3 is located on the upper part of the grip rod 1. It also includes: a vacuum hose 4, wound and coiled around the non-grip portion of the grip rod 1, serving as the main suction channel; the vacuum hose 4 can be detached from the grip rod 1 and extended for use; an air inlet pipe 5, located at the air inlet of the vacuum hose 4, which is a rigid pipe and secured to the locking block 3; and an air outlet pipe 6, located at the air outlet of the vacuum hose 4. It is also a rigid pipe; two mounting blocks 7 are respectively fixed to the outer sides of the pipe walls at both ends of the suction hose 4; a metal shaping hose 8 is set on the outer side wall of the suction hose 4 through the mounting blocks 7, and the metal shaping hose 8 is used to support the suction hose 4 and keep it in a certain shape when it is pulled out and bent into a certain shape; a dust hood 9 is installed at the inlet of the air inlet pipe 5; a dust collection cylinder 10 is set inside the pipe wall of the air outlet pipe 6, and the pipe walls of the dust collection cylinder 10 and the air outlet pipe 6 at corresponding positions are provided with matching ventilation holes 16 and filters (not shown in the figure), and the dust collection cylinder 10 is used to collect the sucked-in dust; a rotary... Button 11 is threaded onto the air outlet of the air outlet pipe 6. Button 11 is used to limit the dust collection cylinder 10 within the pipe wall of the air outlet pipe 6. Mounting housing 12 is fixedly installed within the pipe wall of the air inlet pipe 5. Impeller 13 is rotatably installed within the pipe wall of the air inlet pipe 5, and the impeller 13 is located between the mounting housing 12 and the dust collection hood 9. Motor 14 is sealed inside the mounting housing 12. The output shaft of motor 14 passes through the mounting housing 12 and is connected to the rotation shaft of impeller 13. After placing the vacuum cleaner stably using the placement seat 2, remove the air inlet pipe 5 from the locking block 3, and then remove the vacuum hose 4 from the handle. After removing the handle 1, the user holds the air inlet pipe 5 and brings the dust cover 9 close to the area to be vacuumed. The impeller 13 is driven by the motor 14 to rotate, causing the dust on the cleaning area to be drawn from the dust cover 9 into the vacuum hose 4. The sucked-in dust will be filtered by the dust collection cylinder 10, and the sucked-in air will be discharged from the ventilation hole 16. After use, the vacuum hose 4 is wound around the handle 1, which makes it convenient to quickly store the vacuum cleaner while reducing the space occupied by the vacuum cleaner. The surface of the handle 1 has a textured grip to improve the user's grip comfort when carrying the vacuum cleaner.

[0022] like Figure 1 and Figure 2 As shown, the grip 1 has a battery mounting slot 102 inside for installing the battery. The opening of the battery mounting slot 102 of the grip 1 is fitted with a battery cover 101 by threads. The battery installed in the grip 1 supplies power to the motor 14. It should be noted that the battery is a rechargeable battery. The power supply wire is built into the side wall of the vacuum hose 4. A hanging rope 17 is connected to the top of the battery cover 101. The hanging rope 17 can be used to hang the vacuum cleaner for easy storage, thereby saving the space occupied by the vacuum cleaner when it is not in use.

[0023] like Figure 3 and Figure 4 As shown, it also includes sound insulation cotton 15. A section of sound insulation cotton 15 is attached to the inner wall of the vacuum cleaner hose 4. The sound insulation cotton 15 tightly covers the inner wall of the vacuum cleaner hose 4. The sound insulation cotton 15 is used to reduce the noise when the vacuum cleaner sucks in dust and improve the user experience of the vacuum cleaner.

[0024] like Figure 2 As shown, a light 18 is installed on the vacuum hood 9. The light 18 is symmetrically distributed at both ends of the vacuum hood 9. The battery installed in the handle 1 powers the light 18. The light 18 is equipped with an easy-to-use switch. The light 18 is used to illuminate the area in front of the vacuum hood 9. In corners with poor lighting, when the user removes the vacuum hose 4, they can turn on the light 18 on the vacuum hood 9 to illuminate the dust or impurities in the corner, thereby improving the practicality of the vacuum cleaner.

[0025] like Figure 4 and Figure 5 As shown, the bottom surface of the base 2 at the bottom of the grip 1 is a flat surface. A suction cup 19 is provided inside the surface of the grip 1. The suction cup 19 is used to improve the stability of the vacuum cleaner when it is placed horizontally and to prevent the vacuum cleaner from tipping over and being damaged during use.

[0026] When using the vacuum cleaner, the user first places the entire device stably on the work surface using the base 2 at the bottom of the handle 1. The suction cup 19 built into the bottom of the base 2 is used to secure the vacuum cleaner and prevent it from tipping over during use. Next, the user can remove the air inlet pipe 5 from the latch 3 and unwrap the vacuum hose 4 from the handle 1 to lengthen and bend it into the desired shape. Because the vacuum hose 4 has a metal shaping hose 8 on its outer side wall, the vacuum hose 4 can maintain a specific shape according to the user's needs, thus facilitating access to... For hard-to-reach areas, the user holds the air inlet pipe 5 and brings the vacuum hood 9, installed at the inlet of the air inlet pipe 5, close to the area to be cleaned. Then, the motor 14 is started. The motor 14, located inside the mounting housing 12, begins to run, directly driving the impeller 13 to rotate at high speed through the output shaft. As the impeller 13 rotates, a strong negative pressure zone is generated inside the vacuum hose 4, thus creating suction at the vacuum hood 9. This suction is sufficient to suck up dust, debris, and other impurities from the floor or furniture surface into the vacuum hose 4. The sucked-in air and impurities then pass through the suction... The dust hose 4 and the exhaust pipe 6 then enter the dust collection cylinder 10. The dust collection cylinder 10 effectively separates dust from air, allowing clean air to be discharged through the ventilation hole 16, while the dust is retained in the dust collection cylinder 10. In addition, to reduce the noise of the vacuum cleaner during use, a section of sound-absorbing cotton 15 is attached to the inner wall of the suction hose 4, effectively absorbing and reducing the vibration sound caused by airflow. Furthermore, for corners with insufficient light or dark places, users can turn on the lights 18 installed at both ends of the vacuum cover 9. These lights 18 are located inside the handle 1. Powered by a battery, it can be easily controlled via a switch, providing users with a clear view for more accurate dust location and removal. After use, users simply need to turn off the motor 14, rewind the vacuum hose 4 onto the handle 1, and clip the air inlet pipe 5 back onto the clip 3. This not only facilitates storage but also reduces the space occupied by the vacuum cleaner. When carrying it, the textured surface of the handle 1 increases the comfort of holding it, while the hanging rope 17 connected to the top allows the device to be hung on the wall or other places, further saving storage space.
