Detailed implementation manners

[0048] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments. However, the scope of protection required by the present invention is not limited to the specific embodiments described below.

[0049] Such as Figure 1As shown, a non-straight-tube hair-sucking shaver structure based on air multiplication technology includes a handle portion 1 and a shaving and hair-sucking portion 2. The handle portion 1 is connected to the side wall of the shaving and hair-sucking portion 2, and the outer walls of the connection form an angle 4, and the degree of the angle 4 is 10-170 degrees. In this embodiment, the preferred value of the angle 4 is 30 degrees, at which time the handle portion is most convenient and comfortable to hold.

[0050] Specifically, the handle part 1 and the shaving and suction part 2 are both hollow structures; a fan motor 11 with a blower is installed at the tail of the handle part 1 cavity. The fan motor adopts a high-speed brushless motor. The brushless motor has low noise during operation, and because there is no carbon brush wear, the service life is longer than that of ordinary motors. Its rotation speed is above 100,000 revolutions per minute, and it can generate a strong wind speed of more than 65m / s when in use. The fan motor adopts a motor and fan integrated design. A first blowing channel 12 is formed in the front of the cavity. When the fan motor is started, a large amount of airflow is generated through the first blowing channel 12, and the width of the first blowing channel 12 changes from wide to narrow along the wind speed direction.

[0051] A partition 27 is provided in the middle of the shaving and hair suction part 2, and the partition 27 divides the shaving and hair suction part into an upper part and a lower part. The upper part of the shaving and hair suction part is a cavity structure, and a cutter head motor 28 is installed at the front end of the lower sealed part of the shaving and hair suction part, and a second circuit board 29 is installed at the rear section. The second circuit board 29 is mainly used to control the start and stop of the cutter head motor 28.

[0052] The first blowing channel 12 is connected to the upper cavity of the shaving and sucking part through a slit gap 3. The upper cavity of the shaving and sucking part 2 is divided into a suction channel 21 and a second blowing channel 24. The air channel 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.

[0053] The slit gap 3 includes a first slit wall 31 and a second slit wall 32. The first slit wall 31 is a side wall of the shaving and sucking part, which is curved in an arc shape from the shaving and sucking part to the inner cavity of the handle part; the second slit wall 32 is an inner wall of the handle part that smoothly extends inwards toward the second blowing channel 24 to form an arc-shaped arc surface. The arc shape formed by the inward buckling here can make the wind blow out from the slit gap 3 along the inward buckling direction toward the second blowing channel 24, thereby preventing the wind from blowing out from the suction channel 21. The first slit wall 31 and the second slit wall 32 are arranged opposite to each other to form the slit gap 3.

[0054] Specifically, the handle part 1 and the shaving and suction part 2 are assembled by a right cover 5, a left cover 6, an air duct accessory 7, an outer shell 8 and a lower shell 9. The left cover 6 is closed on the upper side of the right cover 7, and the outer shell 8 is sleeved on the right cover 5 and the left cover 6. A fan motor 11 is arranged in the cavity between the left cover 6 and the right cover 5 to form a first blowing channel 12. A suction channel 21 is arranged at the front end of the right cover 5, and a second slit wall 32 with an arc-shaped surface is arranged at the connection between the suction channel 21 and the first blowing channel 12. The air duct accessory 7 is installed at the tail of the suction channel 21 of the right cover 5, and the upper outer wall of the air duct accessory 7 is tilted in an arc shape toward 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 to each other to form a slit gap 3. The hollow cavity inside the air duct accessory 7 is the second blowing channel 24, the fan motor 11 is arranged on the rear side of the first 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 blowing channel 24 in the air duct accessory 7 to form a partition, the lower shell 9 is covered under the right cover 5, and 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 blowing channel 24, and the lower part is provided with a cutter head motor 28, a spring buckle 25, a second circuit board 29, and a power plug-in connector 5, wherein the cutter head motor 28 is arranged on the front end suction channel 21 side, the spring buckle 25 is arranged on both sides of the front and rear ends of the lower shell 10, and the power plug-in connector 5 is arranged on the rear end second blowing channel 24 side.

[0055] In addition, a conventional control button 101 is arranged on the outer shell of the handle part, and the control button 101 at least includes a power button, a fan motor gear button and a cutter head control button, etc. A conventional filter 102, a metal sheet 103, a filter housing 104 and a power cord 105 are also arranged at the tail of the cavity of the handle part 1.

[0056] The slit gap and the second blowing channel are arranged at an angle, and the angle range of the angle is 0-70 degrees. The arc cross-sectional curvature of the arc-shaped raised first slit wall 31 ranges from 3 to 60 degrees, and the arc-shaped design of the first slit wall 31 allows wind to pass more quickly. The arc cross-sectional curvature of the arc-shaped arc surface of the second slit wall 32 ranges from 120 to 200 degrees. The width of the slit gap 3 becomes narrower from the handle part to the shaving and suction part. Under the condition of stable air output, the design of the slit gap 3 from wide to narrow and the reduction of the air outlet area will lead to an increase in wind speed. The high-speed airflow blown out from the slit gap 3 is ejected at high speed through the second blowing duct 24. Because of the fluid mechanics wall attachment effect, the airflow will flow at high speed along the wall of the second blowing duct 24 when it is blown out from the slit gap 3. According to Bernoulli's principle, a negative pressure area will be generated behind the air outlet of the second blowing duct 24 by the high-speed moving air to form a suction channel 21. This negative pressure area (suction channel 21) will suck in the outside air, and then drive this part of the air to move by the viscosity of the gas. In this process, a suction force will be generated in front of the suction channel 21, sucking in the outside things from the suction channel 21. On the side of the second blowing channel 24, the total amount of moving air is much larger than the high-speed gas itself blown out from the slit gap 3, and the second blowing channel 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 installation area is provided on the side wall extending from the first slit wall and the side wall of the shaving and hair suction part. The circuit board installation area is provided in the cavity of the handle part and below the first blowing channel. The circuit board installation area is used to install a first circuit board 13. Electronic components that need to dissipate heat can be provided on the first circuit board 13. The first circuit board 13 uses an existing integrated circuit board and is mainly used to control the start and stop of the fan motor.

[0057] The high-speed airflow blown out from the first blowing channel 12 passes through the first circuit board 13 and takes away a large amount of heat on the first circuit board 13, thereby providing good heat dissipation conditions for the first circuit board 13 and ensuring the normal operation of the circuit.

[0058] Preferably, the shaving and hair suction part 2 has a suction port 22 for suction and an outlet 23 for outlet. The suction port 22 and the outlet 23 are both provided with spring buckles 24 for assembling accessory heads, and springs 25 are provided inside the spring buckles 24. The suction port 22 can be configured as a cutter head assembly or a dust collector head according to different requirements.

[0059] The air outlet 23 can be configured as a bag - fitting head or a blowing head according to different accessory heads. The bag - fitting head is used to install the slag storage bag 113, and the size of the slag storage bag 113 can be set according to actual needs. When vacuuming, a small slag storage bag 113 can be used; when sucking hair, a larger slag storage bag 113 can be used. In this way, it is not necessary to frequently pour out the hair, greatly improving the efficiency of vacuuming and hair - sucking. At the same time, snap - fasteners 24 and springs 25 are used to install the bag - fitting head, making the replacement more convenient and fast.

[0060] A power external plug - in connector 5 is provided at the air outlet 23 of the hair - shaving and hair - sucking part, which can provide power for the accessory head. The blowing head can be a cold - air head or a hot - air head.

[0061] The hair - shaving and hair - sucking structure of this embodiment can be used for shaving and sucking hair of pets, can also be used for shaving and sucking hair during human hair - cutting, and can also be used alone for daily dust - sucking and hair - sucking. Further, this structure can be applied to any products and scenarios where hair - shaving, hair - sucking, dust - sucking, and hair - sucking are required.

[0062] Specifically, the working principle and process of this embodiment are as follows:

[0063] When the fan motor 11 starts, a large amount of air flow passes through the blowing channel 12 and then blows out through the slit gap 3 at the end of the blowing channel 12. Since the air duct of the slit gap 3 gradually narrows, with a stable air output, the reduction of the air outlet area will lead to an increase in wind speed. The high - speed air flow blown out from the slit gap 3 is ejected at high speed through the second blowing channel 24. Due to the fluid - mechanics wall - attachment effect, the air flow will flow at high speed along the wall of the second blowing channel 24 when blowing out from the slit. According to Bernoulli's principle, a negative - pressure area will be generated behind the slit air outlet of the high - speed moving air to form a suction air duct 21. This negative - pressure area (suction air duct 21) will suck in the outside air, and then drive the movement of this part of the air by the viscosity of the gas. During this process, a suction force will be generated in front of the suction air duct 21 to suck in the outside things from the suction air duct 21. On the side of the second blowing channel 24, the total amount of moving air is much larger than the high - speed gas itself blown out from the slit gap 3, and the second blowing channel 24 will blow out a very strong air flow, greatly increasing the suction force of dust - sucking and hair - sucking.

[0064] The first circuit board 13 is arranged in the blowing channel 1. The high - speed air flow can take 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.

[0065] The sides of the air inlet 22 and the air outlet 23 of the shaving and sucking part are both provided with spring buckles 25, and a spring 26 is provided inside the spring buckles 25. When the accessory head is assembled, the spring buckles 25 will be compressed and contracted, and then rebound to cooperate with the card position on the accessory head to fix the accessory head on the machine body. When the accessory head needs to be replaced, the accessory head can be removed by pressing the spring hook. A power external plug connector is provided at the air outlet 23 at the tail of the shaving and sucking part 2 to provide power for the accessory head.

[0066] The effect of this embodiment with or without the blowing and sucking head: the bagging head 112 is installed on the air outlet 23 side of the shaving and sucking part 1, and a residue storage bag 113 is put on the bagging head. When the shaving head assembly 210 is installed on the suction port side, it is a hair suction shaver. When trimming hair, the trimmed hair will be sucked into the residue storage bag 113, which can prevent the hair from scattering on the ground, and can reduce the subsequent hair cleaning work for the user.

[0067] When the brush head 106 is installed on the side of the air suction port 22, it can be used to remove hair debris and dust on the body, and can also be used to clean carpets and sofas in daily life; when the combing head 107 is installed on the side of the air suction port 22, it can be used for daily combing of hair. During the combing process, some debris adhering to the body can be sucked into the residue storage bag 113 through the process of combing hair; when the dust suction head 108 is installed on the side of the air suction port 22, it can be used as a vacuum cleaner. When a blower head 109 is provided on the side of the blower channel 12, it can be used as a blower. A cold air head and a hot air head can be provided on the side of the blower channel 12. When a cold air head 110 is provided, only cold air can be blown. When a hot air head 111 is provided, both cold air and hot air can be blown. A power terminal is provided at the connection end of the hot air head 111 and the shaving and hair suction part. When the hot air head 111 is matched with the power supply external plug-in connector on the shaving and hair suction part, electric energy can be provided for the hot air head. Electronic components such as electric heating wires and negative ion generators are provided on the hot air head. When the switch is turned on, hot air is blown out, and when the switch is turned off, cold air is blown out.

[0068] The present invention is provided with a fan motor on the handle part, a first blowing channel is provided in the blowing direction of the fan motor, a suction channel and a second blowing channel are provided on the shaving and hair suction part, the first blowing channel and the second blowing channel are connected through a slit gap, a large amount of wind is blown out when the fan motor is started, and the wind is blown out from the slit gap through the first blowing channel, a negative pressure area is generated at the front end of the second blowing channel, and a large suction force is generated, which greatly improves the dust collection and hair washing effects. In addition, the suction channel and the second blowing channel are not provided with a filter screen, which will not cause the suction force of the vacuum cleaner to be blocked and weakened; there is no hair storage bin inside the vacuum cleaner, and an assembly bag connected to the air outlet is used to store hair, which greatly increases the hair storage capacity, thereby greatly improving the overall suction and dust collection effects and improving the efficiency.
