[0045] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below in combination with examples, but the scope of protection of the utility model is not limited to the following specific examples.

[0046] As Figure 1 Shown, a non-cylinder type based on air multiplication technology's can suck hair shaver structure, including handle part 1 and shaving and hair suction part 2, the handle part 1 with the side wall of shaving and hair suction part 2 is connected and the angle 4 formed by the junction outside wall, the degree of the angle 4 is 10-170 degrees, in the preferred value of angle 4 in this embodiment is 30 degrees, when handle part is most convenient comfortable when holding.

[0047] Specifically, the handle part 1 and the inside of the shaving and sucking part 2 are both hollow structures; a fan motor 11 integrated with a fan is installed at the tail of the hollow part of the handle part 1, which is a high-speed brushless motor, and the brushless motor has low noise during operation and a longer service life than ordinary motors because of no carbon brush wear, and its rotating speed is above 100,000 rpm, and it can generate a strong wind speed of 65 m / s or above when in use, and the fan motor is designed in an integrated manner of motor and fan. The front part of the hollow part forms a first blowing channel 12, and a large amount of airflow generated when the fan motor is started passes through the first blowing channel 12, and the first blowing channel 12 narrows in width along the direction of the wind speed.

[0048] A partition 27 is arranged in the middle of the shaving and sucking part 2, which divides the shaving and sucking part into an upper part and a lower part, the upper part of the shaving and sucking part is a hollow structure, and the lower part of the shaving and sucking part is sealed at the front end with a cutter motor 28 and at the rear end with a second circuit board 29, which is mainly used to control the start and stop of the cutter motor 28.

[0049] The first blowing channel 12 is connected to the upper hollow part of the shaving and sucking part through a slit gap 3, and the upper hollow part of the shaving and sucking part 2 is divided into a suction channel 21 and a second blowing channel 24, the air duct along the blowing direction of the slit gap 3 is the second blowing channel 24, and the other end is the suction channel 21.

[0050] 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 and raised in the direction from the shaving and sucking part to the inner cavity of the handle part; the second slit wall 32 is a smooth extension of the inner wall of the handle part in the direction of the second blowing channel 24, which forms a circular arc surface, and the circular arc surface formed by the inner buckle can make the wind blow out of the slit gap 3 in the direction of the inner buckle to the second blowing channel 24, avoiding the wind blowing out of the suction channel 21. The first slit wall 31 and the second slit wall 32 are oppositely arranged to form the slit gap 3.

[0051] Specifically, the handle part 1 and the shaving and sucking part 2 are assembled by the right cover 5, the left cover 6, the air duct accessory 7, the outer shell 8 and the lower shell 9. The left cover 6 is combined with the upper side of the right cover 7. The outer shell 8 is sleeved on the right cover 5 and the left cover 6. The fan motor 11 is arranged in the cavity between the left cover 6 and the right cover 5 and forms the first blowing channel 12. The right cover 5 is provided with the air suction channel 21 at the front end. The second slit wall 32 with a circular arc surface is arranged at the connection position of the air suction channel 21 and the first blowing channel 12. The air duct accessory 7 is arranged at the tail of the air suction channel 21 of the right cover 5. The outer wall of the air duct accessory 7 is circularly arched upward to the inner cavity of the handle part, forming the first slit wall 31. The first slit wall 31 and the second slit wall 32 are oppositely arranged to form the slit gap 3. The hollow cavity of the air duct accessory 7 is the second blowing channel 24. The fan motor 11 is arranged at the rear side of the first blowing channel 12 of the right cover 5. The bottom of the air suction channel 21 of the right cover 5 and the bottom of the second blowing channel 24 of the air duct accessory 7 are connected to form the partition plate 27. The lower shell 9 is combined below the right cover 5. The cavity between the lower shell 9 and the right cover 5 is divided into two parts by the partition plate 27. The upper part is provided with the air suction channel 21 and the second blowing channel 24. The lower part is provided with the cutter motor 28, the elastic buckle 25, the second circuit board 29 and the power supply external connector 5.

[0053] The slit gap is arranged at an angle with the position of the second air blowing channel, and the angle ranges from 0 to 70 degrees. The arc-shaped first slit wall 31 has a cross-sectional arc angle ranging from 3 to 60 degrees, and the arc-shaped design of the first slit wall 31 allows the air to pass through more quickly. The arc-shaped second slit wall 32 has a cross-sectional arc angle ranging from 120 to 200 degrees. The slit gap 3 is wider at the handle portion and narrower at the shaving and hair suction portion. In the case of stable air volume, the design of the slit gap 3 becoming narrower causes the area of the air outlet to decrease, which leads to an increase in air speed. The high-speed airflow blown out of the slit gap 3 is sprayed out of the second air blowing channel 24 at high speed. According to the Bernoulli principle, a negative pressure area is formed behind the air outlet of the second air blowing channel 24, which forms the air suction channel 21. This negative pressure area (air suction channel 21) sucks in external air, and then drives the movement of this part of air by the viscosity of the gas. In this process, a suction force is generated in front of the air suction channel 21, which sucks external things into the air suction channel 21. On the side of the second air blowing channel 24, the total amount of moving air is much larger than the high-speed gas blown out of the slit gap 3 itself, and the second air blowing channel 24 blows out a very strong airflow. Specifically, the width of the slit gap 3 ranges from 1 to 20 mm, and the length of the slit gap 3 ranges from 5 to 50 mm. The first slit wall and the extended side wall of the shaving and hair suction portion are provided with a circuit board mounting area, which is arranged in the handle portion cavity and below the first air blowing channel. The circuit board mounting area is used to mount the first circuit board 13, and the first circuit board 13 can be provided with electronic components that need to be cooled. The first circuit board 13 uses an existing integrated circuit board mainly for controlling the start and stop of the fan motor.

[0054] The high-speed airflow blown out of the first air blowing channel 12 carries away a large amount of heat on the first circuit board 13, which can provide good cooling conditions for the first circuit board 13 and ensure the normal operation of the circuit.

[0055] Preferably, the air suction direction of the shaving and hair suction portion 2 is the air suction port 22, and the outlet direction is the air outlet 23. The air suction port 22 and the air outlet 23 are provided with a snap buckle 24 for assembling a head, and the snap buckle 24 is internally provided with a spring 25. The air suction port 22 can be configured as a cutter head assembly or a dust collection head according to different requirements.

[0056] The air outlet 23 can be configured as a bagging head or a blowing head according to different requirements, the bagging head is used for mounting a residue storage bag 113, the size of the residue storage bag 113 can be set according to actual requirements, when dust is sucked, a small residue storage bag 113 can be used, when hair is sucked, a larger residue storage bag 113 can be used, so that hair does not need to be poured frequently, and the efficiency of dust and hair suction is greatly improved, and the bagging head is installed by using the elastic buckle 24 and the spring 25, so that replacement is more convenient and fast.

[0057] The air outlet of the hair cutting and sucking part is provided with a power supply external connector 5, which can provide power supply for the accessory head. The blowing head can be a cold air head or a hot air head.

[0058] The hair cutting and sucking structure of the embodiment can be used for cutting and sucking hair of pets, can be used for cutting and sucking hair of people in the process of haircutting, and can be used alone for daily dust and hair suction. Further, the structure can be applied to any product and scene that can be used for hair cutting and sucking.

[0059] Specifically, the working principle and working process of the embodiment are as follows:

[0060] When the fan motor 11 is started, a large amount of airflow is generated through the blowing channel 12, and then is blown out through the slit gap 3 at the end of the blowing channel 12. Since the slit gap 3 wind channel gradually narrows, under the condition that the air volume is stable, the reduction of the air outlet area will lead to the increase of the wind speed. The high-speed airflow blown out of the slit gap 3 is high-speed sprayed through the second blowing channel 24. Due to the wall effect of fluid mechanics, the airflow blown out of the slit will flow at high speed along the wall of the second blowing channel 24. According to Bernoulli's principle, a negative pressure area formed by the high-speed moving air behind the air outlet of the slit will form an air suction channel 21. The negative pressure area (air suction channel 21) will suck the air outside, and then drive the air to move by the viscosity of the gas. In this process, a suction force is generated in front of the air suction channel 21, and the outside is sucked into the air 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 blown out of the slit gap 3, and the second blowing channel 24 blows a very strong airflow, greatly increasing the suction force of dust and hair suction.

[0061] The first circuit board 13 is arranged in the blowing channel 1, and the high-speed airflow can take away the heat of the first circuit board 13, so as to provide good heat dissipation condition for the first circuit board 13 and ensure the normal operation of the circuit.

[0062] The suction port 22 and the air outlet 23 of the shaving and hair suction part are provided with elastic buckles 25, the elastic buckles 25 are internally provided with springs 26, when the accessory head is assembled, the elastic buckles 25 are compressed and contracted, and then rebound to cooperate with the clamping positions on the accessory head, so that the accessory head is fixed on the machine body, when the accessory head is to be replaced, the elastic buckles are only pressed to detach the accessory head.

[0063] The effect of the embodiment matched with the accessory head without blowing and suction: the air outlet 23 side of the shaving and hair suction part 1 is assembled with a sleeve bag head 112, and a residue storage bag 113 is sleeved on the sleeve bag head. When the shaving cutter head assembly 210 is assembled on the suction port side, it is a hair suction shaver, and the trimmed hair is sucked into the residue storage bag during trimming, so that the hair is prevented from scattering on the ground, and the subsequent work of cleaning the hair is reduced for the user.

[0064] When the hair brush head 106 is assembled on the suction port 22 side, it can be used to remove hair debris and dust on the body, and can also be used to clean carpets and sofas in life; when the combing head 107 is assembled on the suction port 22 side, it can be used for daily combing hair, and some sundries adhered to the body can be sucked into the residue storage bag through the combing process; when the dust suction head 108 is assembled on the suction port 22 side, it can be used as a dust collector. When the blowing head 109 is assembled on the blowing channel 12 side, it can be used as a blower, and the blowing channel 12 side can be provided with a cold air head and a hot air head. When the cold air head 110 is assembled, only cold air can be blown, and when the hot air head 111 is assembled, cold air and hot air can be blown. The hot air head 111 is provided with power terminals at the connection end of the shaving and hair suction part, which are in communication with the power external plug-in connector on the shaving and hair suction part when matched, so as to provide electric energy for the hot air head. The hot air head is provided with electric heating wires, negative ion generators and other electronic elements, and when the switch is turned on, hot air is blown out, and when the switch is turned off, cold air is blown out.

[0065] The utility model discloses a fan motor is arranged in handle part, the blowing direction of fan motor is equipped with first blowing channel, the shaving and hair suction part is provided with suction channel and second blowing air duct, first blowing channel and second blowing air duct are connected through slit gap, and when fan motor starts, the large wind volume is blown out through first blowing channel from slit gap, and the large suction air power is generated in the negative pressure area behind second blowing air duct, so as to greatly improve the effect of dust collection and hair washing. In addition, the suction channel and the second blowing air duct are not provided with filter screen, which will not cause the suction force of the dust collector to be blocked and weakened. The dust collector is not provided with a hair storage bin, and the assembled bag connected to the air outlet is used to store hair, which greatly increases the capacity of the hair storage bin, thereby greatly improving the suction and dust collection effect and improving the efficiency.
