Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaners and hair dryers, specifically to a non-cylinder vacuuming structure based on 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 lint remover technology is relatively advanced, it still has some shortcomings, such as: insufficient suction capacity, especially when vacuuming hair, because the dust box or lint collection compartment has a small capacity, requiring frequent emptying when cleaning large areas, affecting work efficiency; in addition, hair easily clogs the filter, further reducing capacity and increasing cleaning frequency; insufficient suction power: the machine power is insufficient, making it difficult to deal with deep hair or stubborn dirt, resulting in poor cleaning effect; and significant suction power decay, with suction power decreasing after prolonged use, affecting continuous cleaning ability.

[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 issues, a non-cylindrical vacuum cleaner structure was proposed, which offers superior suction power, effective cleaning, and high efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A non-cylinder type vacuum cleaner structure based on air multiplication technology includes a handle and a vacuuming part, wherein the handle is connected to the side wall of the vacuuming part and the included angle formed by the outer walls of the connection is 10-170 degrees.

[0009] Both the handle and the suction unit have hollow structures inside.

[0010] The handle cavity is equipped with an integrated fan motor at the rear end, and a first air blowing channel is formed at the front of the cavity. The width of the first air blowing channel gradually narrows along the direction of wind speed.

[0011] The first blowing channel is connected to the internal cavity of the dust collection unit through a slit gap. The internal cavity of the dust collection unit is divided into a suction channel and a second blowing channel. The air duct along the air outlet direction of the slit gap is the second blowing channel, and the other end is the suction channel.

[0012] The slit gap includes a first slit wall and a second slit wall. The first slit wall is the side wall of the dust suction part, which is curved upwards in an arc shape from the dust suction part toward the inner cavity of the handle part. The second slit wall is the inner wall of the handle part, which extends smoothly inwards toward the second blowing channel to form an arc-shaped surface. The first slit wall and the second slit wall are arranged opposite to each other to form the slit gap.

[0013] Preferably, the arcuate curvature of the first slit wall ranges from 3 to 60 degrees.

[0014] Preferably, the arcuate cross-section of the second slit wall has an arcuate radius of 120-200 degrees.

[0015] Preferably, 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.

[0016] Preferably, the slit gap width gradually narrows from the handle portion to the suction portion.

[0017] Preferably, the width of the slit gap is in the range of 1-20 mm;

[0018] Preferably, the length of the slit gap is in the range of 5-50 mm.

[0019] Preferably, a circuit board mounting area is provided on the side wall extending from the first slit wall and the side wall of the dust collection part. The circuit board mounting area is located in the cavity of the handle part and below the first air blowing channel. The circuit board mounting area is used to install a control circuit board.

[0020] Preferably, the suction direction of the dust collection unit is the suction port, and the outlet direction is the outlet. Both the suction port and the outlet side are provided with spring clips for attaching the accessory head, and the spring clips are provided with springs inside.

[0021] Preferably, the air intake can be configured as a vacuum cleaner head or a brush head, depending on different needs.

[0022] Preferably, the air outlet can be configured as a bag-covering head or a blower head depending on different needs;

[0023] Specifically, the dust extraction unit has an external power connector at the air outlet, which can provide power to the accessory head.

[0024] Specifically, the blower head can be a cold air head or a hot air head.

[0025] The beneficial technical effects of this utility model are as follows: A fan motor is set in the handle to form a first air blowing channel. The first air blowing channel is connected to the inner cavity of the dust collection part through a slit gap. When the fan motor is started, a large amount of air is blown out through the first air blowing channel and the slit gap, creating negative pressure in the second air blowing channel, thereby generating a strong suction force. In addition, the dust collection part is directly set as a cavity without a filter screen. The dust and hair sucked in are directly blown out from the air outlet through the suction channel, which can continuously suck up dust with a strong air force, greatly improving the suction efficiency and work efficiency.

Detailed Implementation

[0043] 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.

[0044] like Figure 1 As shown, a non-cylindrical vacuum cleaner structure based on air multiplication technology includes a handle 1 and a vacuuming part 2. The handle 1 is connected to the side wall of the vacuuming part 2, and the outer wall of the connection forms an angle 4. The angle 4 is 10-170 degrees. In this embodiment, the preferred value of the angle 4 is 35 degrees, which is the most convenient and comfortable to hold.

[0045] Specifically, both the handle part 1 and the dust collection part 2 have hollow cavity structures. A fan motor 11 integrated with the blower is installed at the rear of the cavity in the handle part 1. This fan motor uses a high-speed brushless motor, which operates with low noise and has a longer service life than ordinary motors due to the absence of carbon brush wear. Its speed exceeds 100,000 revolutions per minute, and it can generate a strong wind speed of over 65 m / s during use. The fan motor adopts an integrated motor and fan design. A first airflow channel 12 is formed at the front of the cavity. When the fan motor starts, a large amount of airflow is generated through the first airflow channel 12, which narrows in width along the wind direction.

[0046] The first blowing channel 12 is connected to the internal cavity of the dust collection part through a slit gap 3. The internal cavity of the dust collection part 2 is divided into a suction channel 21 and a second blowing channel 24. The air duct along the air outlet direction of the slit gap 3 is the second blowing channel 24, and the other end is the suction channel 21.

[0047] The slit gap 3 includes a first slit wall 31 and a second slit wall 32. The first slit wall 31 is the side wall of the suction part, which curves upwards in an arc shape from the suction part towards the inner cavity of the handle part. The second slit wall 32 is the inner wall of the handle part that smoothly extends inwards towards the second air blowing channel 24, forming an arc-shaped surface. This inward curve allows the air to blow out of the slit gap 3 in the direction of the inward curve towards the second air blowing channel 24, preventing the air from blowing out from the suction channel 21. The first slit wall 31 and the second slit wall 32 are arranged opposite each other to form the slit gap 3.

[0048] Specifically, the handle part 1 and the dust collection part 2 are assembled from a right cover 5, a left cover 6, an air duct accessory 7, an air intake accessory 8, an air blower accessory 9, and a lower shell 10. The left cover 6 is fitted onto the upper side of the right cover 5, the air intake accessory 8 is installed at the front end of the lower shell 10, the air blower accessory 9 is installed at the rear side of the air intake accessory 8, the air duct accessory 7 is installed inside the right cover 5, and the right cover 5 is fitted onto the upper part of the lower shell 10. The cavity formed between the right cover 5 and the air intake accessory 8 forms an air intake channel 21. The second slit wall 32 is formed on one side of the air intake channel 21 inside the right cover 5. The right cover 5, together with the air duct accessory 7, the air outlet accessory 9, the left cover 6, and the lower shell 10, forms a first air blower channel 12. The right cover 5, together with the air duct accessory 7 and the air outlet accessory 9, forms a second air outlet channel 24.

[0049] The suction duct accessory 8 has a semi-circular structure with its tail end curving inward into a trumpet shape. It is connected to a second slit wall 32. The internal cavity formed by the combination of the accessory 7 and the right cover 5 is the suction channel 21. The air duct accessory 7 and the blowing duct accessory 9 are combined to form a columnar hollow structure. The internal cavity is the second blowing air duct 24. The outer wall of this structure is inwardly curved to form an arc surface, which is the first slit wall 31.

[0050] Additionally, a control button 101 is conventionally provided on the outer shell of the handle section. The control button 101 includes at least a power button and a fan motor speed button. The rear of the handle section 1 cavity also contains a conventional filter 102, a metal sheet 103, a filter housing 104, and a power cord 105.

[0051] The arc-shaped raised section of the first slit wall 31 has an arc angle ranging from 3 to 60 degrees, and the arc-shaped design of the first slit wall 31 allows air to pass through more quickly. The arc-shaped curved surface of the second slit wall 32 has an arc angle ranging from 120 to 200 degrees. The width of the slit gap 3 gradually narrows from the handle to the suction section. Under stable airflow conditions, the narrowing design of the slit gap 3 reduces the air outlet area, leading to an increase in air velocity. The high-speed airflow blown out from the slit gap 3 is ejected at high speed through the second air duct 24. Due to the fluid dynamics wall adhesion effect, the airflow will flow at high speed along the wall of the second air duct 24 when it is blown out. According to Bernoulli's principle, the high-speed air will create a negative pressure area behind the air outlet of the second air duct 24, forming a suction channel 21. This negative pressure area (suction channel 21) 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 21, drawing in external objects from the suction channel 21. On the side of the second air duct 24, the total amount of moving air is much greater than the high-speed gas blown out from the slit gap 3 itself, and the second air duct 24 will blow out a very strong airflow. Specifically, the width of the slit gap 3 ranges from 1 to 20 mm; the length of the slit gap 3 ranges from 5 to 50 mm. A circuit board mounting area is provided on the side wall extending from the first slit wall and the side wall of the dust collection part. The circuit board mounting area is located in the cavity of the handle part and below the first air blowing channel. The circuit board mounting area is used to install the control circuit board 13.

[0052] The high-speed airflow blown out by the first air blowing channel 12 carries away a large amount of heat from the control circuit board 13, providing good heat dissipation conditions for the control circuit board 13 and ensuring the normal operation of the circuit.

[0053] Preferably, the suction unit 2 has an air intake 22 and an air outlet 23. Both the air intake 22 and the air outlet 23 are equipped with spring clips 24 for attaching accessory heads, and each spring clip 24 contains a spring 25. The air intake 22 can be configured with a vacuum cleaner head or a brush head, depending on the specific needs.

[0054] The air outlet 23 can be configured as a bag-covering head or a blower head according to different needs. The cover head is used to install the sludge bag 113. The size of the sludge bag 113 can be set according to actual needs. When vacuuming dust, a small sludge bag 113 can be used, and when vacuuming hair, a larger sludge bag 113 can be used. This eliminates the need to frequently empty the hair, greatly improving the efficiency of vacuuming dust and hair. At the same time, the bag-covering head is installed using a snap buckle 24 and a spring 25, making replacement more convenient and quick.

[0055] The dust extraction unit has an external power connector 5 at its air outlet, which can provide power to the accessory head. The blower head can be a cold air head or a hot air head.

[0056] 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.

[0057] Specifically, the working principle and process of this embodiment are as follows:

[0058] When the fan motor 11 starts, a large amount of airflow is generated through the air blowing channel 12 and then blown out through the slit gap 3 at the end of the air blowing channel 12. As the air duct of the slit gap 3 gradually narrows, the reduction in the air outlet area will lead to an increase in wind speed when the air volume is stable. The high-speed airflow blown out from the slit gap 3 is ejected at high speed through the second air blowing channel 24. Due to the fluid dynamic wall adhesion effect, the airflow will flow at high speed along the wall of the second air blowing channel 24 when it is blown out from the slit. According to Bernoulli's principle, the high-speed air will generate a negative pressure area behind the slit air outlet to form a suction channel 21. This negative pressure area (suction channel 21) 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 21, which will draw in the outside objects from the suction channel 21. On the side of the second air blowing channel 24, the total amount of moving air is much greater than the high-speed gas blown out from the slit gap 3 itself. The second air blowing channel 24 will blow out a very strong airflow, which greatly increases the suction power of dust collection.

[0059] The control circuit board 13 is located inside the air blowing channel 1. The high-speed airflow can carry away the heat of the control circuit board 13, providing good heat dissipation conditions for the control circuit board 13 and ensuring the normal operation of the circuit.

[0060] Both the suction port 22 and the exhaust port 23 of the vacuum unit are equipped with spring clips 25. Each spring clip 25 contains a spring 26. When an accessory head is installed, the spring clip 25 is compressed and then springs back to engage with the locking mechanism on the accessory head, securing it to the machine body. To replace the accessory head, simply press the spring clip to remove it. An external power connector is located at the exhaust port 23 at the rear of the vacuum unit 2, providing power to the accessory head.

[0061] This embodiment features the following effects when used with a blower / suction head: A matching bag head 112 is attached to the air outlet 23 side of the suction unit 1, and a dust collection bag 113 is placed on the bag head. When a brush head 106 is attached to the air inlet 22 side, it can be used to remove hair, debris, and dust from the body, and can also be used to clean carpets and sofas in daily life. When a comb head 107 is attached to the air inlet 22 side, it can be used for daily hair combing. During the combing process, some debris adhering to the body can be sucked into the dust collection bag. When a vacuum head 108 is attached to the air inlet 22 side, it can be used as a vacuum cleaner. When the blower head 109 is attached to the side of the blower channel 12, it can be used as a hair dryer. The side of the blower channel 12 can be equipped with either a cold air head or a hot air head. When the cold air head 110 is attached, it can only blow cold air. When the hot air head 111 is attached, it can blow both cold and hot air. The connection end between the hot air head 111 and the vacuum cleaner is equipped with a power terminal. When connected, it is connected to the external power connector on the vacuum cleaner to provide power to the hot air head. The hot air head is equipped with electronic components such as a heating wire and a 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.

[0062] This invention features a fan motor in the handle, forming a first airflow channel. The suction unit has a suction channel and a second airflow duct. The first and second airflow channels are connected by a slit. When the fan motor starts, a large volume of air is blown through the first airflow channel and the slit, creating a negative pressure zone behind the second airflow duct, resulting in a stronger suction force and significantly improving the vacuuming and shampooing effects. Furthermore, the suction and second airflow channels do not have filters, preventing a weakening of the vacuum cleaner's suction power. The vacuum cleaner does not have an internal hair collection compartment; instead, an external bag attached to the air outlet is used to collect hair, greatly increasing the hair collection capacity and thus significantly improving the overall suction and dust collection effect and increasing efficiency.

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.
