Detailed Description of the Preferred Embodiment
[0016] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.
[0017] As Figure 1-2 shown, a stepless variable speed vacuum cleaner of the present utility model includes a vacuum cleaner body. The vacuum cleaner body includes a front shell 1, a rear shell 2, and a handle 3. The front shell 1 and the rear shell 2 are detachably connected. The front end of the front shell 1 is connected with an extension nozzle 4, and the front end of the extension nozzle 4 is detachably connected with an extension nozzle brush cap 5. The rear end of the rear shell 2 is provided with a blowing nozzle 6 and a blowing nozzle brush 7. A suction nozzle 8 is arranged inside the front shell 1. The rear end of the suction nozzle 8 is connected with the rear shell 2. A filter element 9 is arranged outside the rear end of the suction nozzle 8. A motor 10 and a blower 11 are arranged inside the rear shell 2. The blowing nozzle 6 is arranged on the rear shell 2 corresponding to the suction nozzle 8. A rotary switch 12 is arranged on the handle 3. A speed changer 13 connected to the rotary switch 12 is arranged inside the handle 3. A circuit board 14 connected to the speed changer is also arranged. A battery 15 is arranged inside the handle 3. The battery 15 is connected with the charging interface 16 on the handle 3.
[0018] The stepless variable speed vacuum cleaner of the present utility model mainly includes a front shell 1, a rear shell 2 and a handle 3. Among them, the front shell 1 and the rear shell 2 are detachably connected. The front shell 1 is equivalent to a dust collection shell. The garbage adsorbed by the vacuum cleaner will gather in the front shell 1. After it is full, it can be disassembled and emptied. The operation is simple and the use is convenient. This stepless variable speed vacuum cleaner is a small vacuum cleaner and can be applied in fields such as home and vehicle. By setting an extension nozzle 4 and an extension nozzle brush cap 5 on the front shell 1, it is ensured that small-volume garbage such as dust, paper scraps, and sundries can be accurately adsorbed into the vacuum cleaner; by setting a blowing nozzle 6 and a blowing nozzle brush 7 at the rear end of the rear shell, it is ensured that the scattered garbage can be blown together and then adsorbed, further facilitating dust collection; by setting a suction nozzle 8 in the front shell 1 and communicating it with the blowing nozzle 8, the vacuum cleaner not only has the function of sucking dust, but also has the function of blowing air, ensuring high dust collection efficiency; by setting a filter element 9 on the outer side of the rear end of the suction nozzle 8, garbage with a slightly larger volume cannot enter the interior of the vacuum cleaner and cause blockage, ensuring that the sucked garbage can only gather in the front shell 1 and will not damage the vacuum cleaner; by setting a motor 10 and a blower 11 in the rear shell 2 and connecting them to a circuit board 13, it is used to control the opening and closing of the vacuum cleaner; by setting a rotary switch 12 and a speed changer in the handle, it is ensured that this vacuum cleaner can adjust the adsorption power of the vacuum cleaner according to the quantity and volume of the garbage, with strong practicability, better adsorption effect, and more energy-saving and environmental protection; when the rotary switch 12 is in use, it can be rotated clockwise or counterclockwise. When the rotary switch 12 is rotated clockwise, the rotation speed of the blower 11 increases, and the suction force of the vacuum cleaner also increases synchronously. When the rotary switch 13 is rotated counterclockwise, the rotation speed of the blower 11 decreases, and the suction force of the vacuum cleaner also decreases synchronously, for adjusting the suction force of the vacuum cleaner; by setting a battery 14 in the handle, with two batteries, it is used to provide power for the vacuum cleaner. Among them, a charging interface 15 is installed on the handle and connected to the battery for facilitating charging of the vacuum cleaner.
[0019] In a preferred embodiment, referring to Figure 1 and 2, a limit block 16 is provided at the rear end of the extension nozzle 4 of the continuously variable transmission vacuum cleaner, and the limit block 16 is adapted to a card slot (not shown in the figure) inside the front shell 1. An "L"-shaped bayonet 17 is provided on the outer side of the rear end of the front shell 1, and a card block adapted to the bayonet (not shown in the figure) is provided on the inner side of the front end of the rear shell 2. A plurality of positioning posts 18 are provided at the bottom of the rear shell 2, and positioning holes 19 adapted to the positioning posts 18 are provided on the handle 3. The suction nozzle 8 and the blowing nozzle 6 are of a conical structure. The front shell 1 is made of a transparent plastic material. By providing the limit block 16 at the upper part of the rear end of the extension nozzle 4, the extension nozzle 8 is clamped on the limit block 16 on the inner wall of the front shell 1, ensuring that the extension nozzle 4 will not easily fall off and affect the use; by providing the bayonet 17 at the rear end of the front shell 1 and the card block at the front end of the rear shell 2, and setting the bayonet and the card block as an "L" shape, it is convenient for the front shell 1 and the rear shell 2 to be detachably clamped, and further convenient to pour out the dust in the front shell 1; by providing a plurality of positioning posts 18 at the bottom of the rear shell 2 and a plurality of positioning holes 19 on the handle 3, during installation, the positioning posts 18 are clamped in the positioning holes 19, ensuring that the handle 3 and the rear shell 2 are also detachably connected; by setting both the suction nozzle 8 and the blowing nozzle 6 as conical structures, specifically, the diameter of the end closer to the dust is smaller than the diameter of the end farther from the dust, further increasing the suction force and blowing force and improving the dust suction efficiency; by making the front shell 1 of a transparent plastic material, but not limited to plastic materials, it can also be acrylic or glass or other transparent materials, so that when the front shell 1 is filled with garbage, it can be poured out in time to ensure that the use effect of the vacuum cleaner is not affected.
