Description

Technical Field

[0001] This utility model relates to the field of vacuuming and hair removal, specifically to a hair-collecting shaver structure using air multiplication technology. Background Technology

[0002] A hair shaving and vacuuming device is a grooming tool specifically designed for trimming hair. It combines shaving and vacuuming functions, helping consumers easily address some hair trimming issues while maintaining a tidy home environment. Existing hair shaving and vacuuming devices typically feature a three-in-one design, allowing for simultaneous trimming, combing, and vacuuming of loose hair, effectively reducing hair scattering throughout the home.

[0003] Hair removal devices primarily use a motor to drive the blades to shave and trim hair, while simultaneously using the high-speed rotation of the motor to generate negative air pressure to remove hair.

[0004] Although existing hair removal and shaving technology is relatively advanced, it still has some shortcomings, such as: insufficient suction capacity, especially when cleaning large areas, as the dust box or hair collection compartment has a small capacity and needs to be emptied frequently, affecting work efficiency; the filter structure is designed, and if the filter is not cleaned for a long time, it may block the airflow, resulting in weakened airflow and insufficient suction. In addition, hair easily clogs the filter, increasing the cleaning frequency and affecting work efficiency; insufficient suction power: the motor power is insufficient to deal with deep hair or stubborn dirt, resulting in poor cleaning effect.

[0005] Therefore, it is necessary to improve the existing shaving and hair-collecting structure to enhance the shaving and hair-collecting power and improve the shaving and hair-collecting effect. Utility Model Content

[0012] 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.

[0013] 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 a first blowing air duct. The front end of the upper shell includes an arched structure and an upper shell bottom plate, and the cavity formed by the arched structure and the upper shell bottom plate forms a suction air duct. The internal cavity of the first air duct accessory forms a second blowing air duct.

[0014] The front sidewall of the first air duct accessory is arc-shaped and raised; the tail of the arched structure at the front end of the upper shell is provided with an arc-shaped surface around the air outlet of the first air duct, which covers the front of the arc-shaped raised part of the first air duct accessory and is arranged opposite to the arc-shaped raised part to form a narrow gap.

[0015] 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.

[0024] Preferably, the air intake can be configured as a blade assembly or a vacuum cleaner head, depending on different needs.

[0025] Preferably, the air outlet can be configured as a bag-covering head or a blower head depending on different needs.

[0026] 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 gap between the first blowing duct and the slit, creating a negative pressure zone behind the second blowing duct, thus generating a strong suction force, greatly improving the dust and hair removal effect.

[0045] 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.

[0046] like Figure 1-11 As shown, a hair-suction shaver 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.

[0047] 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.

[0048] 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. The blade motor 12 is installed in the space formed by the second air duct accessory 4 and the lower shell 2. The blade motor 12 is connected to the blade assembly 13 through a rotating shaft. Both the blade motor 12 and the blade assembly 13 are existing structures. Starting the blade motor 12 can drive the blade assembly to perform hair cutting operations.

[0049] 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;

[0050] The first air duct accessory 3 is installed close to the inner wall of the main structure behind the second air duct accessory 4;

[0051] 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.

[0052] 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.

[0053] 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 air blowing duct 101. The front end of the upper shell 1 includes an arched structure 17 and an upper shell bottom plate 18. The arched structure 17 and the upper shell bottom plate 18 are integral structures, and the cavity formed by the arched structure 17 and the upper shell bottom plate 18 forms an air suction duct 103. The internal cavity of the first air duct accessory 3 forms a second air blowing duct 102.

[0054] The front sidewall of the first air duct accessory 3 is a rounded upturned section 31, which allows air to pass through more quickly. The rear of the upper shell's arched structure 17 is surrounded by a rounded arc surface 171 around the air outlet of the first air duct 101. This arc surface covers the front of the rounded upturned section 31 of the first air duct accessory and is positioned opposite to the rounded upturned section 31, forming a narrow gap 9. The rounded arc surface 171 allows air to be blown inwards towards the second air duct 102 when it exits the narrow gap 9, preventing air from being blown out from the suction channel 103. The rounded arc surface 171 covers the front of the rounded upturned section 31 and is positioned opposite to the rounded upturned section 31, forming a narrow gap 9.

[0055] The slit gap 9 and the second air blowing channel 102 are positioned at an angle, the angle of which is 0-70 degrees. The arc of the cross-section of the arc-shaped protrusion 31 is in the range of 3-60 degrees. The arc of the arc-shaped surface 171 is in the range of 120-200 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.

[0056] 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 matches the upper shell. The second air duct accessory 4 includes a front flat cover 41 and a rear inclined surface 42, and the blade motor 12 is installed in the cavity formed by the front flat cover 41 and the front end of the lower shell 2. 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.

[0057] Control buttons 106 are provided on the surface of the upper shell. The control buttons 106 include at least a power button, a fan motor speed button, and a blade control 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.

[0058] 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.

[0059] The air intake 104 accessory head is configured as a vacuum cleaner head or a blower head. The air outlet 105 accessory head is configured as a bag cover head.

[0060] Specifically, the working principle and process of this utility model are as follows:

[0061] 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 is blown 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, which will draw in the outside objects from 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.

[0062] 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.

[0063] The air inlet 104 can be equipped with different blowing and suction heads, and the air outlet 105 is equipped with a matching bag head 110. A slag storage bag 109 is then placed on the bag head 110.

[0064] When the shaver head assembly 13 is installed on the side of the air intake 104, it is a hair suction shaver. When trimming hair, the trimmed hair will be sucked into the shaving bag, which can prevent hair from falling to the ground and reduce the user's subsequent hair cleaning work.

[0065] 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.

[0066] 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.

[0067] When the suction head 113 is installed on the side of the air intake 104, it can be used as a vacuum cleaner.

[0068] 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.

[0069] 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.

[0070] This utility model can be used with different accessory heads to meet different needs in the hair care process. It is multi-functional, easy to operate, and highly applicable, providing users with a better experience.

[0071] 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 a large volume of air through the first blowing duct and out through a narrow gap, creating a negative pressure zone behind the second blowing duct, thus generating a strong suction force that significantly improves dust and hair removal. Furthermore, the suction and second blowing ducts 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 capacity and thus significantly improving overall suction and dust removal efficiency.

[0072] 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.
