[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1:
[0023] Please see the appendix Figure 1 - Appendix Figure 5 A small handheld vacuum cleaner includes a front housing 1 and a rear housing 2. An extension assembly 4 is provided on the front side of the front housing 1, and a filter assembly 3 is located inside it. The filter assembly 3 includes a pre-filter 301 and a rear activated carbon filter 302. The rear activated carbon filter 302 is disposed inside the pre-filter 301. The pre-filter 301 has several sets of circumferentially distributed filter holes 305 on its circumferential surface. A mounting block 303 is fixedly installed at one end of the pre-filter 301, and a sealing ring 304 is fixedly installed at one end of the rear activated carbon filter 302. The front housing 1 and the rear housing 2 are connected by a snap-fit 10. The rear housing 2 has a motor mounting groove 8 inside, and an electric drive mechanism 7 is fixedly installed inside the motor mounting groove 8. Sound-absorbing cotton 9 is fixedly installed on the inner wall of the motor mounting groove 8, and a motor switch 11 is fixedly installed on the outer surface of the rear housing 2. The mounting block 303 is snapped into the inside of the front housing 1, and the sealing ring 304 is set in the slot of the mounting block 303. Several sets of activated carbon mesh 306 arranged in a circular array are fixedly installed on the circumferential surface of the rear activated carbon filter 302.
[0024] If unfiltered or insufficiently filtered air carrying a large amount of dust enters the vacuum cleaner, it will accelerate the wear of components such as the motor and fan in the electric drive mechanism 7. Dust accumulation on the motor windings will affect heat dissipation, causing the motor to overheat and thus shortening its lifespan. The sound-absorbing cotton 9 effectively blocks the noise generated by the motor starting from spreading outward. At the same time, a soundproof cover is also set on the outer surface of the fan. The soundproof cover is made of glass fiber sound-absorbing material, which can also play a sound insulation role. Usually, a metal mesh or a pre-filter with a large pore size 301 is used. Its main function is to perform preliminary filtration and intercept larger impurities such as dust, hair, and debris in the car. This pre-filter 301 can effectively reduce the burden on subsequent filters. The activated carbon mesh 306 in the post-activated carbon filter 302 has a highly developed pore structure and a huge specific surface area, which can adsorb a variety of harmful gases and odors.
[0025] Specifically, firstly, the electric drive mechanism 7 is activated, drawing in dust, hair, and other impurities from inside the vehicle through the suction port of the front housing 1. Larger impurities such as dust, hair, and debris are initially filtered through the filter holes 305 on the surface of the front coarse filter 301. Then, smaller dust particles and gases are effectively filtered through the activated carbon mesh 306 in the rear activated carbon filter 302. The front coarse filter 301 and the rear activated carbon filter 302 are tightly fitted together via a sealing ring 304, ensuring that air can only pass through the designated path and preventing unfiltered air from leaking out. Furthermore, the front coarse filter 301, the rear activated carbon filter 302, and the front housing 1 are all connected by snap-fit mechanisms, facilitating disassembly and cleaning and preventing excessive dust from causing blockages and affecting the suction effect.
[0026] Example 2:
[0027] Please see the appendix Figure 1 - Appendix Figure 4 and appendix Figure 6 Furthermore, based on Embodiment 1, the rear housing 2 has a handheld slot 6 on its rear side, and mounting bases 5 are fixedly installed on the bottom outer surfaces of both the front housing 1 and the rear housing 2. The extension assembly 4 includes an extension suction pipe 401, which is inserted into the suction port of the front housing 1. A mounting plate 402 is fixedly installed on the outer surface of the extension suction pipe 401. Insertion holes are provided at the four corners of the surface of the front housing 1. Insert pins 403 that are compatible with the insertion holes are fixedly installed on the four corners of the side surface of the mounting plate 402 near the front housing 1. A telescopic hose 404 is fixedly installed at the end of the extension suction pipe 401 away from the front housing 1, and a flat pressure head 405 is fixedly installed at the end of the telescopic hose 404 away from the extension suction pipe 401.
[0028] Meanwhile, the extension component 4 allows the operator to clean different areas inside the vehicle with little or no movement. For example, while sitting in the driver's seat, the operator can clean the area under the rear seats by extending the vacuum hose 401 without frequently getting up or changing positions. The flexible nature of the telescopic hose 404 prevents the vacuum cleaner from directly contacting some vulnerable parts or decorations inside the vehicle, thereby reducing the risk of collisions and scratches. The mounting base 5 makes the vacuum cleaner more stable after use, preventing damage to internal components caused by frequent shaking when the car is running. The handheld slot 6 makes it easier for the operator to pick up the vacuum cleaner.
[0029] Specifically, when it is necessary to clean all corners of the car interior, the extension vacuum hose 401 is inserted into the vacuum port of the front housing 1. At this time, the multiple pins 403 on the mounting plate 402 are inserted into the holes of the front housing 1, so that the extension vacuum hose 401 and the front housing 1 form a stable connection, preventing the extension vacuum hose 401 from falling off during use. The telescopic hose 404 is telescopic and, together with the flat pressure head 405, can be extended to various locations inside the car, such as narrow places like the bottom of the seats and the corners of the doors, to achieve comprehensive cleaning and improve cleaning efficiency.
[0030] Working principle of this utility model: This utility model is a small handheld vacuum cleaner. First, the extension suction tube 401 is inserted into the suction port of the front housing 1. At this time, the multiple pins 403 on the mounting plate 402 are inserted into the insertion holes of the front housing 1, so that the extension suction tube 401 and the front housing 1 form a stable connection. The motor switch 11 is turned on, so that the motor in the electric drive mechanism 7 drives the fan to rotate. At the same time, since the telescopic hose 404 is telescopic, it can be extended to various positions in the car with the flat head 405 to suck up dust, hair and other impurities in the car through the suction port of the front housing 1. Then, the pre-filter 301 first filters out larger impurities such as dust, hair, and debris by using the filter holes 305 on its surface. Then, the activated carbon mesh 306 in the post-filter 302 effectively filters out smaller dust particles and gases. The pre-filter 301 and post-filter 302 are tightly fitted together by a sealing ring 304 to ensure that air can only pass through the set path. At the same time, the pre-filter 301, post-filter 302 and the front housing 1 are all connected by a snap-fit method for easy disassembly and cleaning. The whole process is now complete.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
