Description

Technical Field

[0001] This utility model relates to the field of dust and hair suction, specifically to a dust and hair suction structure using air multiplication technology. Background Technology

[0002] A vacuum cleaner or pet lint remover is a household appliance that uses a motor-driven fan to create negative pressure, thereby sucking in air and dust. It is mainly used to clean surfaces such as floors, carpets, and furniture, and can effectively remove dust, hair, debris, and other impurities.

[0003] The principle behind vacuum cleaners and lint removers is that the high-speed rotation of an internal motor drives the blades around the motor to rotate at high speed. At this time, a vacuum is created inside the vacuum cleaner, forming a negative pressure difference with the external atmospheric pressure. Under the action of the pressure difference, the vacuum cleaner will suck in air containing dust and debris from the ground, and the filtered clean air will be discharged from the air outlet at the rear of the vacuum cleaner's fan and motor.

[0004] Although existing vacuum cleaner and hair remover technology is relatively advanced, it still has some shortcomings: when used to remove hair, if there is a lot of hair, the suction power is insufficient, and the filter will become clogged when there is too much hair, further reducing the suction power and resulting in poor hair removal effect and low work efficiency. At the same time, if the hair storage compartment is not spacious enough, it needs to be emptied frequently, which greatly prolongs the hair removal time, resulting in poor hair removal effect and low efficiency.

[0005] Therefore, existing technologies need to be improved to enhance the suction power and efficiency of vacuum cleaners. Utility Model Content

[0006] To address the aforementioned technical challenges, a dust collection structure based on air multiplication technology was proposed, which boasts strong suction, excellent dust extraction performance, and high efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dust and hair suction structure using air multiplication technology, comprising an upper shell, a lower shell, a first air duct accessory, a second air duct accessory, a middle plate, and a fan motor.

[0008] The upper shell and the lower shell are fastened together to form the main body of the structure, which is an internal cavity structure.

[0009] The second air duct fitting is installed close to the inner wall of the main structure at the front end of the lower shell inner wall;

[0010] The first air duct accessory is installed close to the inner wall of the main structure behind the second air duct accessory;

[0011] The middle plate covers the lower shell and is tightly connected to the tail of the first air duct. The fan motor and circuit board are installed sequentially from front to back in the cavity formed by the middle plate cover and the lower shell.

[0012] The space formed by the first air duct accessory, the upper shell, the lower shell, and the rear end of the second air duct accessory forms the first air blowing duct. The front end of the upper shell has a round arch structure. The air suction duct is formed between the second air duct accessory and the round arch structure of the upper shell. The internal cavity of the first air duct accessory forms the second air blowing duct.

[0013] The front sidewall of the first air duct accessory is an arc-shaped upturn; the tail of the upper shell arch structure extends smoothly inward toward the second air blowing channel to form an arc-shaped surface, which covers the front of the arc-shaped upturn and is positioned opposite to the arc-shaped upturn to form a narrow gap.

[0014] Preferably, the bottom of the first air duct accessory is a flat structure, and the upper part is a semi-circular arched structure that matches the upper shell.

[0015] Preferably, the second air duct component includes a front rising arc surface and a rear slope.

[0016] Preferably, the arc of the curved section is in the range of 3-60 degrees.

[0017] Preferably, the arcuate cross-section of the arcuate surface has an arcuate radius of 120-200 degrees.

[0018] The feature is that the slit gap and the position of the second air blowing channel are set at an angle, and the angle range is 0-70 degrees.

[0019] Preferably, the slit gap width gradually narrows in the direction of wind speed.

[0020] Preferably, the width of the slit gap is in the range of 1-20 mm;

[0021] Preferably, the length of the slit gap is in the range of 5-50 mm.

[0022] Preferably, the main body of the structure has an air intake inlet and an air outlet in the air outlet direction. Both the air intake and air outlet sides are provided with spring clips for assembling accessory heads, and the spring clips have springs inside.

[0023] Preferably, the air intake can be configured as a vacuum cleaner head or a brush head, depending on different needs.

[0024] Preferably, the air outlet can be configured as a bag-covering head or a blower head depending on different needs.

[0025] The beneficial technical effects of this utility model are as follows: This utility model, through the cooperation of various components, forms a first blowing duct, a second blowing duct, and a suction duct. When the fan motor starts, it blows out a large volume of air through the narrow gap in the first blowing duct. A negative pressure zone is created behind the second blowing duct, resulting in a stronger suction force, greatly improving the dust and hair removal effect. Furthermore, the suction duct and the second blowing duct do not have filters, preventing the vacuum cleaner's suction power from being obstructed or weakened. The vacuum cleaner does not have an internal hair collection chamber; instead, an external bag attached to the air outlet is used to collect hair, greatly increasing the hair collection capacity. Therefore, the overall suction and dust removal effect is significantly improved, and efficiency is increased. Attached Figure Description

[0044] 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 the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0045] like Figure 1-11 As shown, a dust and hair suction structure with air multiplication technology includes an upper shell 1, a lower shell 2, a first air duct accessory 3, a planar structure 32, a second air duct accessory 4, a middle plate 5, and a fan motor 6.

[0046] The upper shell 1 and the lower shell 2 are fastened together to form the main body of the structure, which is an internal cavity structure.

[0047] The second air duct accessory 4 is installed close to the inner wall of the main structure at the front end of the inner wall of the lower shell 2;

[0048] The first air duct accessory 3 is installed close to the inner wall of the main structure behind the second air duct accessory 4;

[0049] The middle plate 5 covers the lower shell 2 and is tightly connected to the tail of the first air duct accessory 3. The fan motor 6 and the circuit board 7 are installed sequentially from front to back in the cavity formed by the middle plate 5 and the lower shell 2. The outer wall of the fan motor 6 is fitted with a silicone sleeve 15. A filter screen 16 is installed between the fan motor 6 and the circuit board 7. The fan motor 6 adopts a fan motor with the fan and motor integrated. The fan motor 6 adopts an existing high-speed brushless motor. The brushless motor has low noise when running, and because there is no carbon brush wear, its service life is longer than that of ordinary motors. Its speed is over 100,000 rpm, and it can generate a strong wind speed of over 65 m / s when in use. It achieves small size and high power. The circuit board 7 integrates various circuits and electronic components, and is connected to the fan motor 6 through electrical signals for controlling the fan motor 6.

[0050] The lower shell is equipped with an external power connector 8 and a power cord 14 at the rear. The power cord 14 and the external power connector 8 are used to connect to an external power source to provide electrical energy.

[0051] The space formed by the first air duct accessory 3, the upper shell 1, the lower shell 3 and the rear end of the second air duct accessory 4 forms a first blowing air duct 101. The front end of the upper shell is an arched structure 17. The second air duct accessory 4 and the arched structure 17 of the upper shell form a suction air duct 103. The internal cavity of the first air duct accessory 4 forms a second blowing air duct 102.

[0052] The front sidewall of the first air duct accessory 3 is a rounded, upturned shape 31, which allows air to pass through more quickly. The rear of the upper shell arched structure 17 extends smoothly inward toward the second air blowing channel 102, forming a rounded arc surface 171. This inward curve allows air to be blown out of the slit gap 9 in the direction of the inward curve toward the second air blowing channel 102, preventing air from being blown out of the suction channel 103. The rounded arc surface 171 covers the front of the rounded, upturned shape 31 and is positioned opposite to the rounded, upturned shape 31 to form the slit gap 9.

[0053] The slit gap 9 and the second air blowing channel 102 are positioned at an angle, with the angle ranging from 0 to 70 degrees. The arc of the cross-section of the arc-shaped protrusion 31 ranges from 3 to 60 degrees. The arc of the arc-shaped surface 171 ranges from 120 to 200 degrees. The width of the slit gap 9 gradually narrows in the direction of the wind speed. This gradually narrowing design, under the condition of stable air volume, will lead to an increase in wind speed due to the reduction in the outlet area. The high-speed airflow blown out from the slit gap 9 is ejected at high speed through the second blowing duct 102. Due to the fluid dynamic wall adhesion effect, the airflow will flow at high speed along the wall of the second blowing duct 102 when it is blown out. According to Bernoulli's principle, the high-speed air will create a negative pressure area behind the outlet of the second blowing duct 102, forming a suction channel 101. This negative pressure area (suction channel 101) will draw in outside air, and then the viscosity of the gas will drive this part of the air to move. During this process, a suction force will be generated in front of the suction channel 101, drawing in external objects from the suction channel 101. On the side of the second blowing channel 102, the total amount of moving air is much greater than the high-speed gas blown out from the slit gap 9 itself. The second blowing channel 102 will blow out a very strong airflow. Specifically, the width of the slit gap 9 ranges from 1 to 20 mm; the length of the slit gap 9 ranges from 5 to 50 mm.

[0054] Preferably, the bottom of the first air duct accessory 3 is a flat structure 32, and the upper part is a semi-circular arched structure 33 that mates with the upper shell. The second air duct accessory 4 includes a rising arc surface 41 at the front end and a sloping surface 42 at the rear end. The rising arc surface 41 at the front end of the second air duct accessory 4 is fastened to the arched structure 17 of the upper shell. The above structures of the first air duct accessory 3 and the second air duct accessory 4 are fully adapted to the main body of the structure, making the suction power of this utility model greater and the dust and hair removal effect better.

[0055] Control buttons 106 are provided on the surface of the upper shell. The control buttons 106 include at least a power button and a fan motor speed button. The inner side wall of the upper shell is provided with a button fixing bracket 107 for supporting the control buttons 106. In addition, air inlets 108 are evenly distributed on the tail side of the fan motor 6 of the lower shell 2 for air intake and heat dissipation.

[0056] Preferably, the main body of the structure has an air intake 104 and an air outlet 105. Both the air intake 104 and the air outlet 106 are provided with spring clips 10 for mounting the fitting head, and the spring clips 10 are provided with springs 11 inside.

[0057] The air intake 104 can be configured as a vacuum cleaner head or a brush head, depending on different needs. The air outlet 105 can be configured as a bag-covering head or a blower head, depending on different needs.

[0058] The dust collection structure in this embodiment can be used for daily dust collection, pet hair collection, and hair collection during haircuts. It is also suitable for any product or scenario that requires dust collection or hair collection.

[0059] Specifically, the working principle and process of this utility model are as follows:

[0060] When the fan motor 6 starts, a large amount of airflow is generated through the first air blowing channel 101 and then blown out through the end of the slit gap 9. As the airflow gradually narrows from the first air blowing channel 101 to the slit gap 9 and then blown out through the slit, the airflow will increase as the air outlet area decreases under the condition of stable airflow. The high-speed airflow blown out from the slit gap 9 is ejected at high speed through the second air blowing channel 102. Due to the fluid dynamics wall adhesion effect, the airflow will flow at high speed along the wall of the second air blowing channel 102 when it blows out from the slit. According to Bernoulli's principle, the high-speed air will create a negative pressure area behind the slit outlet, forming a suction channel 103. This negative pressure area (suction channel 103) will draw in the outside air, and then the viscosity of the gas will drive this part of the air to move. During this process, a suction force will be generated in front of the suction channel 103, drawing things from the outside into the suction channel 103. On the side of the second air blowing channel 102, the total amount of moving air is much greater than the high-speed gas blown out from the slit gap 9 outlet, and the second air blowing channel 102 will blow out a very strong airflow.

[0061] Circuit board 7 is located at the air inlet side of the fan motor 6. During operation, the fan motor 6 draws in a large amount of air, and the high-speed airflow can carry away the heat from the chips on circuit board 7, providing excellent heat dissipation for circuit board 7 and ensuring the normal operation of the circuit. When the accessory head is attached to the air intake 104 and air outlet 105, the spring clip 10 is compressed and then springs back to engage with the locking position on the accessory head, fixing the accessory head to the body. When the accessory head needs to be replaced, simply press the spring clip to remove the accessory head.

[0062] The air intake 104 can be equipped with different blow and suction heads, and the air outlet 105 is equipped with a matching bag head 110. A slag storage bag 117 is put on the bag head 110. The slag storage bag 117 has a large capacity and can store a large amount of hair. It is practical, convenient, and inexpensive. Even disposable slag storage bags 117 can be used. After use, the slag storage bag and hair can be thrown away together, which is convenient and quick.

[0063] When the brush head 111 is installed on the side of the air intake 104, it can be used to remove hair, dust and debris from the body, and can also be used to clean carpets and sofas in daily life.

[0064] When the comb head 112 is installed on the side of the air intake 104, it can be used for daily hair combing. During the combing process, some debris adhering to the body can be sucked into the slag storage bag through the hair combing process.

[0065] When the suction head 113 is installed on the side of the air intake 104, it can be used as a vacuum cleaner.

[0066] When the blower head 114 is attached to the side of the second air blowing channel 102, it can be used as a hair dryer. A protective cover is placed on the side of the air intake channel to cover and protect the motor copper shaft. The side of the second air blowing channel 102 can be equipped with either a cold air head 115 or a hot air head 116.

[0067] When equipped with the cold air head 115, it can only blow cold air. When equipped with the hot air head 116, it can blow both cold and hot air. The connection end of the hot air head 116 to the main structure is equipped with a power terminal. When in use, it is connected to the power external connector 8 on the main structure to provide power to the hot air head 116. The hot air head 116 is equipped with electronic components such as heating wire and negative ion generator. When the switch is turned on, it blows out hot air, and when the switch is turned off, it blows out cold air.

[0068] This invention utilizes various components to form a first blowing duct, a second blowing duct, and a suction duct. When the fan motor starts, it blows out a large volume of air through the gap between the first blowing duct and the slit, creating a negative pressure zone in the second blowing duct, thus generating a strong suction force that significantly improves dust and hair removal. Furthermore, the suction duct and the second blowing duct do not have filters, preventing any reduction in suction power. The vacuum cleaner does not have an internal hair collection chamber; instead, an external bag attached to the air outlet is used to collect hair, greatly increasing the hair collection capacity. This overall improvement in suction and dust removal efficiency is significant.

[0069] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are for convenience only and do not constitute any limitation on the utility model.
