Description

Technical Field

[0001] This utility model belongs to the technical field of handheld vacuum cleaners, and more specifically, it relates to an extension mechanism for handheld vacuum cleaners. Background Technology

[0002] A handheld vacuum cleaner is a common cleaning device that uses an electric motor to drive blades to rotate at high speed, creating negative air pressure inside a sealed housing. Under this pressure difference, air containing dust is drawn in through the suction hood. Dust and other debris pass through the roller brush and extension tube inside the suction hood and enter the filter cup for filtration. The dust and debris are retained in the filter cup, and the filtered air is discharged. The extension mechanism of a handheld vacuum cleaner refers to an additional device or structure designed to increase the suction range or suction power of the handheld vacuum cleaner. This extension mechanism can usually extend the vacuum cleaner's suction port to more distant or harder-to-reach areas, thereby improving the vacuum cleaner's practicality and flexibility.

[0003] However, existing handheld vacuum cleaners have a fixed suction nozzle that cannot be extended or adjusted, resulting in low efficiency and high labor intensity when cleaning large areas. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes an extension mechanism for a handheld vacuum cleaner to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an extension mechanism for a handheld vacuum cleaner, comprising a handheld vacuum cleaner body, a vacuum hood fixedly mounted on the handheld vacuum cleaner body, an extension mechanism provided on the vacuum hood, the extension mechanism including a dual-head motor mounted on the vacuum hood, the output shafts of the dual-head motors each being fixedly mounted with a threaded rod, the threaded rod being threadedly connected to the inside of a threaded cylinder, the threaded cylinder being fixedly mounted on a housing, the housing being provided with an extension hood, a roller brush cloth being rotatably mounted inside the vacuum hood, and retraction mechanisms provided at both ends of the roller brush cloth.

[0007] Furthermore, the dual-head motor is fixedly mounted on the dust collection hood, the housing is fixedly mounted with a connecting plate, and the end of the threaded cylinder away from the dual-head motor is fixedly mounted on the connecting plate.

[0008] Furthermore, one end of the extension cover is fixedly connected to the housing, and the other end is fitted to the dust collection cover.

[0009] Furthermore, there are two of each of the housing and the extension cover. One of the housings is fixedly mounted with a first protective shell, the first protective shell is slidably connected to a second protective shell, and the second protective shell is fixedly mounted on the other housing.

[0010] Furthermore, the first and second protective shells enclose the dual-head motor, threaded rod, threaded cylinder, and connecting plate.

[0011] Furthermore, the shrinking mechanism includes telescopic rods disposed at both ends of the roller brush cloth. One end of the telescopic rod is fixedly installed on the roller brush cloth, and the other end is rotatably installed on the housing. One end of the roller brush cloth is fixedly installed with a connecting cloth, and the other end of the connecting cloth is rotatably installed on the housing. The connecting cloth has a deformation force. Both the dust suction hood and the extension hood are provided with dust suction ports.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The handheld vacuum cleaner extension mechanism proposed in this utility model drives the threaded rod to rotate through a dual-head motor, which in turn moves the threaded cylinder, the housing, and the extension cover, realizing flexible adjustment of the suction length. Users can easily adjust the length of the suction cover according to their actual cleaning needs without having to replace vacuum cleaners of different sizes, thereby improving the convenience of use and suction efficiency. This design not only meets diverse cleaning needs but also enhances the user experience.

[0014] 2. This utility model effectively protects key components such as the dual-head motor, threaded rod, threaded cylinder, and connecting plate by setting a first protective shell and a second protective shell. When the housing and extension cover move, the second protective shell can slide inside the first protective shell, achieving continuous protection for internal parts and avoiding damage caused by external collisions or friction. This design not only extends the service life of the vacuum cleaner but also improves its overall durability and reliability, providing users with a more stable and safe cleaning experience.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0025] Please see Figures 1-4 As shown, this utility model is an extension mechanism for a handheld vacuum cleaner, including a handheld vacuum cleaner body 1, a vacuum cleaner cover 2 fixedly installed on the handheld vacuum cleaner body 1, an extension mechanism provided on the vacuum cleaner cover 2, the extension mechanism including a dual-head motor 3 installed on the vacuum cleaner cover 2, the output shafts of the dual-head motor 3 are both fixedly installed with threaded rods 4, the threaded rods 4 are threadedly connected to the inside of a threaded cylinder 5, the threaded cylinder 5 is fixedly installed on a housing 6, the housing 6 is provided with an extension cover 7, a roller brush cloth 8 is rotatably installed inside the vacuum cleaner cover 2, and the two ends of the roller brush cloth 8 are provided with retraction mechanisms.

[0026] In one embodiment, for the aforementioned dual-head motor 3, the dual-head motor 3 is fixedly mounted on the dust collection cover 2, the housing 6 is fixedly mounted with a connecting plate 9, and the end of the threaded cylinder 5 away from the dual-head motor 3 is fixedly mounted on the connecting plate 9.

[0027] In one embodiment, for the case where one end of the extension cover 7 is fixedly connected to the housing 6 and the other end is attached to the dust cover 2, one end of the extension cover 7 is fixedly connected to the housing 6 and the other end is attached to the dust cover 2.

[0028] In one embodiment, for the aforementioned housing 6, there are two housings 6 and two extension covers 7. One housing 6 is fixedly mounted with a first protective cover 10, and the first protective cover 10 is slidably connected to a second protective cover 11. The second protective cover 11 is fixedly mounted on the other housing 6.

[0029] In one embodiment, the first protective shell 10 and the second protective shell 11 enclose the dual-head motor 3, the threaded rod 4, the threaded cylinder 5 and the connecting plate 9.

[0030] The working principle of the extension mechanism for a handheld vacuum cleaner proposed in this utility model is as follows: when it is necessary to adjust the length of the vacuum cleaner, the dual-head motor 3 is started, which drives the threaded rod 4 to rotate, thereby driving the threaded cylinder 5 to move away from the dual-head motor 3. This causes the housing 6 and the extension cover 7 to move away from the dual-head motor 3, making it easier to adjust the length of the vacuum cover 2 according to the usage requirements. This makes it more convenient and faster to use and improves the vacuuming efficiency.

[0031] It is worth noting that the first protective shell 10 and the second protective shell 11 can protect the dual-head motor 3, the threaded rod 4, the threaded cylinder 5 and the connecting plate 9 from external damage. When the housing 6 and the extension cover 7 move away from the dual-head motor 3, the second protective shell 11 can slide inside the first protective shell 10 to achieve an extension effect, thereby continuing to protect its internal parts from external damage.

[0032] In one embodiment, the shrinking mechanism includes telescopic rods 12 disposed at both ends of the roller brush cloth 8. One end of the telescopic rod 12 is fixedly mounted on the roller brush cloth 8, and the other end is rotatably mounted on the housing 6. One end of the roller brush cloth 8 is fixedly mounted on the connecting cloth 13, and the other end of the connecting cloth 13 is rotatably mounted on the housing 6. The connecting cloth 13 has a deformation force. Both the dust suction hood 2 and the extension hood 7 are provided with dust suction ports 14.

[0033] The working principle of the extension mechanism for a handheld vacuum cleaner proposed in this utility model is that when the housing 6 and the extension cover 7 move away from each other, the telescopic rod 12 is deformed, and the connecting cloth 13 is deformed at the same time, thereby extending the length of the roller brush cloth 8. This makes it easier to adjust the length of the roller brush cloth 8 according to the usage requirements, making it more convenient and faster to use, and improving the cleaning efficiency.
