Description

Technical Field

[0001] This utility model relates to a cleaning device, and more particularly to a vacuum cleaner that automatically sorts and stores particles of different sizes. Background Technology

[0002] In the woodworking industry, a large amount of sawdust and dust are often generated. In the construction industry, after applying putty to walls, sanding, and laying tiles or wood flooring, a large amount of putty dust, cement dust, and sawdust are generated. Most existing vacuum cleaners suck up all the garbage they can within their suction range, which can easily cause large garbage to get stuck in the suction channel and unable to enter the garbage collection bag, thus blocking the suction channel and rendering the vacuum cleaner unusable. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a vacuum cleaner that can automatically sort and store particles of different sizes.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A vacuum cleaner for automatically sorting and storing particles of different sizes includes a frame on which a vacuum fan is mounted. The outlet pipe of the vacuum fan is connected to a collection bag for collecting small dust particles. The suction port of the vacuum fan is connected to a sealed collection bin for collecting large waste particles. The vacuum cleaner also includes a connection port communicating with the collection bin. A vacuum hose is detachably installed on the connection port. The collection bin has a waste outlet with an opening facing away from the suction port of the vacuum fan, and the waste outlet is connected to the connection port.

[0006] The vacuum cleaner is mounted on the top surface of the frame, and the frame is provided with a mounting part below the vacuum cleaner. The upper end of the collection bucket is sealed to the mounting part.

[0007] A sealing ring is provided between the mounting part and the collection bucket.

[0008] The outer edge of the mounting part extends downward with a retaining edge, and the inner side of the retaining edge abuts against the outer side of the collection bucket or is provided with a gap of 0.2-1mm.

[0009] The connection port is located on the side wall of the mounting part, and the waste outlet opening faces downward.

[0010] The suction port of the vacuum fan is equipped with a filter screen.

[0011] The bottom of the frame is equipped with casters.

[0012] The first handle is installed on the frame.

[0013] A second handle is installed on the side wall of the collection bucket.

[0014] The beneficial effects of this utility model are as follows: In this embodiment, a vacuum cleaner is installed on the frame. The outlet pipe of the vacuum cleaner is connected to a collection bag for collecting small dust particles. The suction port of the vacuum cleaner is connected to a sealed collection bin for collecting large waste particles. It also includes a connection port communicating with the collection bin. A vacuum suction pipe is detachably installed on the connection port. The collection bin has a waste outlet with an opening facing away from the vacuum cleaner's suction port. The waste outlet is connected to the connection port. After the vacuum cleaner sucks in waste particles of different sizes through the vacuum suction pipe, when it is discharged from the waste outlet, it will move away from the vacuum cleaner's suction port. The suction power of the vacuum cleaner is sufficient to re-suck in the small waste particles and discharge them into the collection bag, while the large waste particles are collected and stored in the collection bin. This achieves the effect of automatic sorting and storage of large and small particles, avoiding the situation where large waste particles enter the vacuum cleaner and block it.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0021] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0022] Reference Figure 1-3A vacuum cleaner for automatically sorting and storing particles of different sizes includes a frame 1, on which a vacuum fan 2 is mounted. The outlet pipe of the vacuum fan 2 is connected to a collection bag 14 for collecting small dust particles. The suction port of the vacuum fan 2 is connected to a sealed collection bin 3 for collecting large debris particles. The vacuum cleaner also includes a connection port 5 communicating with the collection bin 3. A suction pipe 4 is detachably mounted on the connection port 5. The collection bin 3 has an opening 6 facing away from the suction port of the vacuum fan 2. The waste outlet 6 communicates with the connection port 5. When the vacuum fan 2 sucks in debris of different sizes through the suction pipe 4, it discharges it from the waste outlet 6, moving away from the suction port of the vacuum fan 2. The suction power of the vacuum cleaner 2 is sufficient to re-inhale small particles of waste and discharge them into the collection bag 14, while large particles of waste are collected and stored in the collection bin 3, achieving the effect of automatic sorting and storage of particles of different sizes, and preventing large particles of waste from entering the vacuum cleaner 2 and clogging it.

[0023] In this embodiment, the diameter of the collection bin 3 is much larger than the diameter of the suction pipe 4. This is because the collection bin 3 needs to collect and store large particles of waste, requiring sufficient space. Furthermore, according to the principle of continuity, when the suction fan 2 draws air out of the collection bin 3, it creates a negative pressure inside. During this process, the airflow velocity is relatively low. The collection bin 3, under negative pressure, draws in external air through the suction pipe 4 (i.e., the suction process). With the same amount of air, because the diameter of the suction pipe 4 is smaller, the airflow velocity within the suction pipe 4 is faster, resulting in stronger suction for the waste. The suction is stronger, enabling it to suck up even large particles of trash. When trash enters the large-diameter collection bin 3 through the small-diameter suction pipe 4, the airflow speed decreases sharply, making it impossible to move the large particles of trash. This causes the large particles of trash to remain in the collection bin 3 and be stored there. Although the airflow speed inside the collection bin 3 is low, it is still sufficient to move small dust particles, causing them to move with the airflow towards the suction port of the suction fan 2. Finally, they pass through the suction duct inside the suction fan 2 and are discharged into the collection bag 14 through the exhaust port of the suction fan 2 for storage.

[0024] Furthermore, the direction of the waste outlet 6 is opposite to the air intake of the vacuum fan 2. Therefore, after the waste is discharged from the waste outlet 6, it will first decelerate to a stop, and then the suction force generated by the vacuum fan 2 will cause the waste to accelerate towards the vacuum fan 2.

[0025] In this embodiment, the connection port 5 is located on the side wall of the mounting part 7, and the waste outlet 6 opens downwards. Small particles of waste, due to their lower weight, move a relatively small downward distance when they decelerate to a stop. Large particles of waste, due to their greater weight, move a relatively large downward distance when they decelerate to a stop. The further away from the vacuum cleaner 2, the weaker the suction. Therefore, only small particles of waste are close to the vacuum cleaner 2 and within its suction range. Large particles of waste, being relatively far away, are not affected by the suction of the vacuum cleaner 2. Furthermore, the direction of gravity is opposite to the direction of the suction of the vacuum cleaner 2, further ensuring that large particles of waste are not sucked into the vacuum cleaner 2, thus preventing potential blockages (such as...). Figure 3 As shown, A represents the trajectory of small particles of waste, and B represents the trajectory of large particles of waste.

[0026] The vacuum cleaner 2 is installed on the top surface of the frame 1. The frame 1 is provided with a mounting part 7 below the vacuum cleaner 2. The upper end face of the collection bucket 3 is sealed to the mounting part 7. A sealing ring 8 is provided between the mounting part 7 and the collection bucket 3.

[0027] Since the collection bin 3 needs to be under negative pressure to properly suck up the garbage, the collection bin 3, the mounting part 7, and the vacuum fan 2 need to be sealed.

[0028] The outer edge of the mounting part 7 extends downward to form a retaining edge 9. The inner side of the retaining edge 9 abuts against the outer side of the collection bucket 3 or is provided with a gap of 0.2-1mm. The retaining edge 9 serves as a guide and positioning element for the installation of the collection bucket 3, so that the upper surface of the collection bucket 3, the mounting part 7, and the sealing ring 8 can make better contact and fit.

[0029] Furthermore, the collection bucket 3 is connected to the mounting part 7 by a snap-fit. During installation, the collection bucket 3 is placed under the mounting part 7 and lifted. By bending the snap-fit, the collection bucket 3 will move towards the mounting part 7. During this process, the sealing ring 8 is compressed, thereby further improving the sealing performance of the collection bucket 3. (This type of snap-fit ​​is a metal snap-fit, commonly used to fix buckets and lids together. In use, the snap-fit ​​is usually installed on the bucket. Bending the snap-fit ​​will press the lid against the bucket, thereby fixing it. This type of snap-fit ​​can be purchased directly from the market.)

[0030] The suction port of the vacuum fan 2 is equipped with a filter screen 10. The filter screen 10 allows some large but low-density debris, such as foam, to enter the interior of the vacuum fan 2, further reducing the possibility of the vacuum fan 2 being blocked.

[0031] The bottom of the frame 1 is equipped with casters 11, and the frame 1 is equipped with a first handle 12. By pulling the product with the first handle 12, it can clean a larger area. The side wall of the collection bucket 3 is equipped with a second handle 13 for easy access to the collection bucket 3.
