[0002] A vacuum cleaner is a household appliance primarily used to remove dust and fine particles from floors, carpets, furniture, and other surfaces. It works based on vacuum suction, using a built-in motor to drive a fan at high speed, creating negative pressure inside the vacuum cleaner and drawing air, along with dust and debris, into a collection device. Vacuum cleaners typically come with different types of nozzles and attachments to suit various cleaning needs, such as floor brushes, crevice tools, and dust brushes. The invention of the vacuum cleaner has greatly simplified the process of household cleaning, reducing the labor intensity of using traditional brooms and dustpans. Modern vacuum cleaners come in a wide variety, including upright, canister, handheld, and cordless models. Cordless vacuum cleaners have become increasingly popular in recent years due to their portability and flexibility. Furthermore, some high-end vacuum cleaners are equipped with intelligent features such as automatic suction adjustment, dust full indicator lights, and HEPA filtration systems, further enhancing cleaning performance and user experience. Vacuum cleaners are not only widely used in homes but also play an important role in industrial, commercial, and medical fields. It effectively removes allergens such as bacteria, pollen, and pet dander, improving indoor air quality, and is especially suitable for people with allergies or respiratory diseases. With continuous technological advancements, the performance and functions of vacuum cleaners are constantly improving, bringing more convenience to daily life.

[0003] Currently, if dust and particles enter the motor or other mechanical parts of a vacuum cleaner, the airflow channels (such as fan blades and exhaust vents) may become clogged. This blockage restricts airflow, reduces suction power, and affects cleaning performance. In severe cases, it can lead to motor overheating and increase the risk of motor damage. Therefore, this solution does not meet current needs, and we propose an air-filtered vacuum cleaner. Utility Model Content

[0013] This utility model has the following beneficial effects:

[0014] 1. This air-filtered vacuum cleaner, through its filter plate, allows air to enter the air passage from the suction head when the vacuum cleaner is started. The air then flows through the filter plate to the connecting pipe. The filter plate prevents large particles from entering the internal components of the vacuum cleaner, reducing airflow blockage, ensuring smooth airflow, and extending the vacuum cleaner's lifespan. This solves the problem of dust and particles potentially clogging the airflow passages (such as fan blades and exhaust ports) if they enter the motor or other mechanical parts. Blockage restricts airflow, reduces suction power, and affects cleaning performance. In severe cases, it can lead to motor overheating and increase the risk of motor damage.

Detailed Implementation

[0022] 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.

[0023] Example 1: This example aims to address the issue that if dust and particles enter the vacuum cleaner's motor or other mechanical components, the vacuum cleaner's airflow channels, such as fan blades and exhaust vents, may become clogged. Clogging restricts airflow, reduces the vacuum cleaner's suction power, and affects cleaning performance. In severe cases, it may cause the motor to overheat, increasing the risk of motor damage. Please refer to [link to relevant documentation]. Figure 1-5 An air-filtering vacuum cleaner includes a device cylinder 110 and a main body 120. The main body 120 is installed on the side of the device cylinder 110. The main body 120 includes a suction head 121 and a connecting pipe 122. The suction head 121 is connected to the side of the device cylinder 110 through the connecting pipe 122. A filter plate 123 is detachably installed inside the suction head 121. A connecting bolt 124 connects the suction head 121 and the filter plate 123.

[0024] The suction head 121 has a suction port 125 on its side and an air passage chamber 130 inside. The suction port 125 and the air passage chamber 130 are connected to the connecting pipe 122. The suction head 121 has a sliding groove 131 on its side, and a slider 132 is connected to the side of the filter plate 123. The sliding groove 131 has a sliding channel 133 inside. The slider 132 is a wedge-shaped block, and the sliding channel 133 is a wedge-shaped groove. The slider 132 and the sliding channel 133 slide and engage, providing a tight engagement. When the slider 132 slides into the sliding channel 133, the wedge structure gradually tightens, ensuring a secure connection between the filter plate 123 and the suction head 121 and preventing loosening during use.

[0025] In this embodiment: With the filter plate 123, when the vacuum cleaner is started, gas enters the air passage chamber 130 from the suction head 121, flows through the filter plate 123 to the connecting pipe 122, and blocks large particles from entering the internal components of the vacuum cleaner, reducing airflow blockage, ensuring smooth airflow, and extending the vacuum cleaner's lifespan. This solves the problem that if dust and particles enter the vacuum cleaner's motor or other mechanical parts, the airflow channels such as fan blades and exhaust ports may become blocked. Blockage restricts airflow, reduces the vacuum cleaner's suction power, and affects cleaning performance. In severe cases, it may cause the motor to overheat, increasing the risk of motor damage.

[0026] Example 2 aims to address the issue of loose filter plate 123. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1-5 A fixed post 134 is connected to the inner wall of the sliding groove 131, and a fixed plate 135 is connected to the end of the fixed post 134. The fixed plate 135 is a threaded plate. A first rotating groove 140 is opened on the side of the suction head 121, and a second rotating groove 141 is opened on the side of the filter plate 123. The first rotating groove 140 and the second rotating groove 141 are respectively threaded grooves. The connecting bolt 124 is a threaded bolt, and the connecting bolt 124 is threadedly engaged with the first rotating groove 140 and the second rotating groove 141. A through groove 142 is opened inside the connecting bolt 124, and a rotating post 143 is slidably connected inside the through groove 142. The rotating post 143 is threaded inside, and the rotating post 143 is rotatably engaged with the fixed plate 135.

[0027] In this embodiment, the connecting bolt 124 is used to cooperate with the filter plate 123. During installation, the filter plate 123 is inserted into the sliding groove 131, and then the connecting bolt 124 is threaded into the first rotating groove 140 and the second rotating groove 141. The rotating column 143 is then threaded into the side of the fixed plate 135. The double-layer threaded connection, with multiple points of fixation, increases the stability of the structure. Both the filter plate 123 and the connecting bolt 124 are more firmly positioned in the designated location, reducing the risk of loosening or falling off during use.
