Description

A non-cylindrical hair-suction shaver structure based on air multiplication technology Technical Field

[0001] This invention relates to the field of vacuum cleaners and hair dryers, and specifically to a non-cylinder type hair-collecting shaver structure based on 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. Summary of the Invention

[0006] To address the aforementioned technical issues, a non-cylindrical hair-suctioning shaver structure was proposed, which features strong shaving and suction power, excellent shaving and suction effect, and high efficiency.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A non-cylindrical hair-suction shaver structure based on air multiplication technology includes a handle and a hair-suction part, wherein the handle is connected to the sidewall of the hair-suction part and the included angle formed by the outer walls of the connection is 10-170 degrees.

[0009] Both the handle and the shaving / sucking section have hollow internal structures.

[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 hair-shaving and hair-suction section is provided with a partition in the middle, which divides the hair-shaving and hair-suction section into an upper part and a lower part. The upper part of the hair-shaving and hair-suction section has a hollow structure, and the front end of the lower part of the hair-shaving and hair-suction section is equipped with a blade motor, and the rear end is equipped with a second circuit board.

[0012] The first blowing channel is connected to the upper cavity of the shaving and hair suction part through a slit gap. The upper cavity of the shaving and hair suction part 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.

[0013] The slit gap includes a first slit wall and a second slit wall. The first slit wall is the side wall of the shaving and hair-suction part, which curves upward in an arc shape from the shaving and hair-suction part toward the inner cavity of the handle part. The second slit wall is the inner wall of the handle part that extends smoothly inward toward the second blowing channel to form an arc-shaped surface. The arc cross-section of the arc-shaped surface of the second slit wall has an arc range of 120-200 degrees. The first slit wall and the second slit wall are arranged opposite each other to form the slit gap.

[0014] Preferably, the handle and the shaving and suction part are assembled from a right cover, a left cover, an air duct accessory, an outer shell, and a lower shell.

[0015] The left cover fits onto the upper side of the right cover, and the cavity between the left and right covers forms the first air blowing channel;

[0016] The air duct fittings are installed at the tail of the air intake channel of the right cover, and the fan motor is located at the rear of the first air blowing channel at the upper end of the right cover;

[0017] The lower shell is closed below the right cover, and the cutter head motor is installed at the front end of the cavity between the lower shell and the right cover.

[0018] 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.

[0019] Preferably, the arcuate curvature of the first slit wall ranges from 3 to 60 degrees.

[0020] Preferably, the slit gap width gradually narrows from the handle portion to the shaving and hair-absorbing portion.

[0021] Preferably, the width of the slit gap is in the range of 1-20 mm;

[0022] Preferably, the length of the slit gap is in the range of 5-50 mm.

[0023] Preferably, a circuit board mounting area is provided on the side wall extending from the first slit wall and the side wall of the shaving and hair-absorbing 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.

[0024] Preferably, the air inlet in the suction direction of the hair-shaving and suction section is an air inlet, and the air outlet in the outlet direction is an air outlet. Both the air inlet and the air outlet are provided with spring clips for attaching the accessory head, and the spring clips are provided with springs inside.

[0026] Preferably, the air outlet can be configured as a bag-covering head or a blower head depending on different needs;

[0027] Specifically, the air outlet of the shaving and suction unit is equipped with an external power connector, which can provide power to the accessory head.

[0028] Specifically, the blower head can be a cold air head or a hot air head.

[0029] The beneficial technical effects of this invention are as follows: This invention features an integrated fan motor with a first airflow channel in the direction of airflow. The first airflow channel is connected to the upper cavity of the shaving and hair-collecting part through a slit gap. When the fan motor starts, it blows out a large amount of air through the first airflow channel and out through the slit gap. This creates negative pressure at the front end of the second airflow channel, thereby generating suction. Furthermore, the upper part of the shaving and hair-collecting part is directly set as a cavity without a filter screen. The sucked-in dust and hair are directly blown out through the air outlet through the suction channel, allowing for continuous high-power suction without causing blockage. This results in good shaving and hair-collecting effect and high efficiency. Attached Figure Description

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments. However, the scope of protection of this invention is not limited to the specific embodiments described below.

[0044] As shown in Figure 1, a non-cylindrical hair-suction shaver structure based on air multiplication technology includes a handle 1 and a hair-suction part 2. The handle 1 is connected to the side wall of the hair-suction 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 30 degrees, which is the most convenient and comfortable to hold.

[0045] Specifically, both the handle part 1 and the shaving and hair-suction 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 is a high-speed brushless motor. Brushless motors have low noise during operation and, due to the absence of carbon brush wear, have a longer service life than ordinary motors. 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 direction of the wind speed.

[0046] The hair-shaving and hair-suction section 2 has a partition 27 in the middle, which divides the hair-shaving and hair-suction section into an upper part and a lower part. The upper part of the hair-shaving and hair-suction section has a hollow structure. The lower part of the hair-shaving and hair-suction section has a sealed front end with a blade motor 28 installed, and a sealed rear section with a second circuit board 29 installed. The second circuit board 29 is mainly used to control the start and stop of the blade motor 28.

[0047] The first blowing channel 12 is connected to the upper cavity of the shaving and hair suction part through a slit gap 3. The upper cavity of the shaving and hair suction 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.

[0048] 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 shaving and suction part, and it curves upwards in an arc shape from the shaving and suction part towards the inner cavity of the handle. The second slit wall 32 is the inner wall of the handle 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.

[0049] Specifically, the handle part 1 and the shaving and suction part 2 are assembled from a right cover 5, a left cover 6, an air duct accessory 7, a shell 8, and a lower shell 9. The left cover 6 is fitted onto the upper side of the right cover 7, and the shell 8 is fitted onto the right cover 5 and the left cover 6. A fan motor 11 is installed in the cavity between the left cover 6 and the right cover 5 to form a first air blowing channel 12. The front end of the right cover 5 is provided with an air suction channel 21. The connection between the air suction channel 21 and the first air blowing channel 12 is provided with a second slit wall 32 with an arc-shaped surface. The air duct accessory 7 is installed at the tail of the air suction channel 21 of the right cover 5. The upper outer wall of the air duct accessory 7 is curved upwards in an arc shape towards the inner cavity of the handle part to form a first slit wall 31. The first slit wall 31 and the second slit wall 32 are arranged opposite each other to form a slit gap 3. The hollow cavity inside the air duct accessory 7 is the second air blowing channel 24. The fan motor 11 is located behind the first air blowing channel 12 at the upper end of the right cover 5. The bottom of the suction channel 21 in the right cover 5 is connected to the bottom of the second air blowing channel 24 in the air duct accessory 7 to form a partition. The lower shell 9 is closed under the right cover 5. The partition 27 divides the cavity between the lower shell 9 and the right cover 5 into two parts. The upper part is provided with the suction channel 21 and the second air blowing channel 24. The lower part is provided with the blade motor 28, the spring buckle 25, the second circuit board 29, and the power external connector 5. The blade motor 28 is located on the front suction channel 21 side, the spring buckle 25 is located on both sides of the front and rear ends of the lower shell 10, and the power external connector 5 is located on the rear second air blowing channel 24 side.

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

[0051] The slit gap and the second air blowing channel are positioned at an angle, with the angle ranging from 0 to 70 degrees. The arc-shaped raised section of the first slit wall 31 has an arc angle ranging from 3 to 60 degrees, allowing 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 shaving and 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 blows out from the slit gap 3. 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 shaving and hair-absorbing 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 first circuit board 13. Electronic components that need heat dissipation can be installed on the first circuit board 13. The first circuit board 13 adopts an existing integrated circuit board and is mainly used to control the start and stop of the fan motor.

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

[0053] Preferably, the suction direction of the shaving and suction unit 2 is the suction port 22, and the outlet direction is the outlet 23. Both the suction port 22 and the outlet 23 are provided with spring clips 24 for attaching accessory heads, and each spring clip 24 contains a spring 25. The suction port 22 can be configured as a blade assembly or a vacuum head, depending on different 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] A power connector 5 is provided at the air outlet 23 of the shaving and suction section to provide power to the accessory head. The blower head can be a cold air head or a hot air head.

[0056] This embodiment of the hair-absorbing and shaving structure can be used for shaving and hair-absorbing pets, as well as for shaving and hair-absorbing during haircuts for people. It can also be used alone for daily dust and hair suction. Furthermore, this structure is applicable to any product and scenario that uses hair shaving, hair suction, and dust suction.

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

[0060] Both the suction port 22 and the exhaust port 23 of the shaving and suction unit are equipped with spring clips 25. Each spring clip 25 contains a spring 26. When the 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 shaving and suction unit 2, providing power to the accessory head.

[0061] This embodiment features the effect of not requiring a blower / suction head: a matching bag head 112 is installed on the side of the air outlet 23 of the shaving and suction unit 1, and a collection bag 113 is placed on the bag head. When the shaving head assembly 210 is installed on the air outlet side, it functions as a suction shaving device. During hair trimming, the trimmed hair is sucked into the collection bag 113, preventing hair from scattering on the ground and reducing the user's subsequent hair cleaning work.

[0062] When the brush head 106 is installed on the side of the air intake 22, it can be used to remove hair and dust from the body, and can also be used to clean carpets and sofas in daily life; when the comb head 107 is installed on the side of the air intake 22, it can be used to comb hair daily. During the combing process, some debris adhering to the body can be sucked into the dust collection bag 113; when the vacuum head 108 is installed on the side of the air intake 22, 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 hair removal part is equipped with a power terminal. When connected, it is connected to the power connector on the hair removal part 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.

[0063] This invention features a fan motor mounted on the handle, with a first airflow channel in the fan motor's blowing direction. The shaving and hair-collecting section has a suction channel and a second airflow duct. The first and second airflow channels are connected by a narrow gap. When the fan motor starts, it blows out a large volume of air through the first airflow channel and exits through the narrow gap, creating a negative pressure zone at the front end of the second airflow duct, thus generating significant suction and greatly improving the vacuuming and shampooing effects. Furthermore, the suction and second airflow channels do not have filters, preventing any reduction in 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 overall vacuuming and dust collection efficiency.

[0064] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are for convenience only and do not constitute any limitation on the invention.
