Description

Technical Field

[0001] This invention relates to the field of cleaning appliance technology, and in particular to a lightweight handheld vacuum cleaner. Background Technology

[0002] Vacuum cleaners are common household cleaning tools. Their working principle involves an electric motor driving blades to rotate at high speed, creating negative air pressure within a sealed casing to suck up dust and debris. Vacuum cleaners can be categorized by structure into upright, canister, and handheld types. Handheld vacuum cleaners are widely used due to their small size, light weight, and ease of use and storage. However, existing handheld vacuum cleaners still suffer from drawbacks such as insufficient portability and uneven weight distribution. Summary of the Invention

[0003] The purpose of this invention is to provide a lightweight handheld vacuum cleaner to solve the problems of existing vacuum cleaners being not lightweight and convenient to use.

[0004] To achieve the above objectives, the present invention provides a lightweight handheld vacuum cleaner, comprising: a dust cup assembly, a motor assembly, and a battery, wherein the motor assembly is detachably connected to the dust cup assembly;

[0005] The dust cup assembly includes a dust cup and a cyclone cone. The cyclone cone is built into the dust cup. At least two first slots are provided on the top inner side of the dust cup. The dust cup is arranged vertically and a second block is provided on the dust cup.

[0006] The motor assembly includes a housing and a motor. The housing has a plurality of first locking blocks that engage with first locking slots. The housing also has a second locking slot where the second locking blocks engage with second locking slots. The motor is built into the housing and is arranged vertically. The battery is located on one side of the motor and is arranged horizontally within the housing.

[0007] As a further description of the above technical solution:

[0008] The dust cup is equipped with a button, and the button is equipped with a limit block, which is inserted into a limit groove on the outer shell.

[0009] As a further description of the above technical solution:

[0010] The outer shell is provided with at least two third slots, and the cyclone cone is provided with a third block, which is engaged in the third slot.

[0011] As a further description of the above technical solution:

[0043] Example 1:

[0044] Please see Figure 1-7 The present invention provides a lightweight handheld vacuum cleaner, comprising: a dust cup assembly 1, a motor assembly 2 and a battery 3, wherein the motor assembly 2 is detachably connected to the dust cup assembly 1;

[0045] The dust cup assembly 1 includes a dust cup 11 and a cyclone cone 12. The cyclone cone 12 is built into the dust cup 11. At least two first slots 4 are provided on the inner side of the top of the dust cup 11. The dust cup 11 is arranged vertically and a second block 5 is provided on the dust cup 11.

[0046] The motor assembly 2 includes a housing 21 and a motor 22. The housing 21 is provided with a plurality of first locking blocks 6, which are engaged in the first locking slots 4. The housing 21 is provided with a second locking slot 7, in which second locking blocks 5 are engaged. The motor 22 is built into the housing 21 and is arranged vertically. The battery 3 is arranged on one side of the motor 22 and is arranged horizontally. The battery 3 is built into the housing 21.

[0047] Specifically, the outer shell 21 has a gripping part 212, which is arranged at an angle.

[0048] Specifically, the inner housing 15 of the motor is provided with a plurality of through holes 17, and a filter HEPA 18 is covered on the through holes 17, and the filter HEPA 18 is sleeved on the inner housing 15 of the motor. The through holes facilitate air circulation.

[0049] Specifically, a HEPA filter cover 19 is provided on the HEPA filter 18, and the HEPA filter cover 19 is inserted into the outer casing 21. A support ring 191 is provided on the HEPA filter cover 19, and the support ring 191 is engaged in the positioning groove 141 on the limiting plate 14. This facilitates the fixing of the HEPA filter cover and reduces the difficulty of disassembly.

[0050] Specifically, the inner housing 15 of the motor is provided with a plurality of first screw holes 151, and the outer housing 21 is provided with studs 211 at the positions corresponding to the first screw holes, and the studs 211 are provided with second screw holes. This makes the inner housing of the motor more secure, reduces vibration during motor operation, and thus reduces noise.

[0051] In summary, due to the adoption of the above technical solution, the beneficial effects of this invention are as follows: the battery is positioned above the grip and on one side of the motor. During use, the weight of the battery and motor shifts towards the suction pipe, transferring their weight to the ground, making the vacuum cleaner more convenient to use and achieving weight reduction. The grip is angled towards the motor, facilitating user operation. The dust cup assembly and motor assembly are two independent modules, allowing for seamless assembly and disassembly. Specifically, the outer shell of the components is engaged in a first slot via a first locking block, and the motor assembly can be detachably connected via a second locking block engaging with the second slot.

[0052] Example 2:

[0053] See Figure 1-7The figure shows a lightweight handheld vacuum cleaner provided by Embodiment 2 of the present invention. This embodiment further improves upon the previous embodiment by providing the following technical solution: A button 8 is provided on the dust cup 11, and a limiting block 81 is provided on the button 8. The limiting block 81 is inserted into a limiting groove 9 on the outer shell 21. The button is connected to the dust cup via a spring at its bottom. By pressing the button, the button can move downwards, causing the limiting block to exit the limiting groove. This allows the outer shell to rotate, separating the first locking slot from the first locking block, thus allowing the outer shell to be removed from the dust cup. The limiting block restricts the rotation of the outer shell. After releasing the button, under the action of the spring, the button moves upwards, and the limiting block inserts into the limiting groove.

[0054] Example 3:

[0055] See Figure 1-7 The figure shows a lightweight handheld vacuum cleaner provided by Embodiment 3 of the present invention. This embodiment further improves upon the previous embodiments by providing the following technical solution: At least two third slots 10 are provided on the outer shell 21, and a third block 13 is provided on the cyclone cone 12. The third block 13 engages within the third slots 10. Three third slots and three third blocks are provided, thus securing the outer side of the outer shell to the dust cup and the inner side of the outer shell to the cyclone cone, making the outer shell more firmly fixed, less prone to loosening, and less prone to noise during operation.

[0056] Example 4:

[0057] See Figure 1-7 The figure shows a lightweight handheld vacuum cleaner provided by Embodiment 4 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: A plurality of limiting plates 14 are provided inside the outer shell 21, and the limiting plates 14 are arranged circumferentially. The limiting plates are integrally formed with the outer shell, ensuring a stable and secure connection. The vertically arranged limiting rods increase the strength of the outer shell and enhance its resistance to deformation.

[0058] Example 5:

[0059] See Figure 1-7 The figure shows a lightweight handheld vacuum cleaner provided by Embodiment 5 of the present invention. This embodiment further improves upon the previous embodiments by providing the following technical solution: A motor inner shell 15 is provided on the motor 22, and a plurality of limiting notches 16 are provided on the motor inner shell 15. A limiting plate 14 is engaged within the limiting notches 16. This structural design allows for more stable motor mounting, reducing vibration during operation and thus minimizing noise.

[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
