[0030] Referring to Figures 1 to 12 , an air duct structure of a hair grooming device includes a main body 1. A first air chamber 3 is provided on one side of the main body 1, and a second air chamber 4 is provided on the other side. A communication channel 5 is provided between the first air chamber 3 and the second air chamber 4 for communicating the first air chamber 3 and the second air chamber 4. An air inlet 31 is provided in the first air chamber 3, a suction device 6 is provided in the second air chamber 4, and a first exhaust port 41 is provided in the second air chamber 4 for communicating the second air chamber 4 with the outside. The air inlet 31, the first air chamber 3, the communication channel 5, the second air chamber 4, and the first exhaust port 41 are sequentially communicated to form a suction air duct.

[0031] Through the above structural arrangement, the air inlet, the first air chamber, the communication channel, the second air chamber, and the first exhaust port are sequentially communicated to form a suction air duct. During use, under the suction action of the suction device, the external air flows through each structural component in the suction air duct in sequence, so that the path of the air flow is extended, that is, the path of the noise propagating to the outside is extended, which can play a certain role in filtering and absorbing the noise, thereby achieving an effective noise reduction effect and improving the operation experience of the user. Moreover, in the above structure, the suction air duct straddles the main body of the hair grooming device, which can make full use of the limited space of the hair grooming device and is conducive to the miniaturization design of the hair grooming device.

[0032] In this embodiment, the first air chamber 3 and the second air chamber 4 are arranged opposite to each other so that a circulation space 104 is formed between the first air chamber 3 and the second air chamber 4, and a channel member 7 is arranged between the first air chamber 3 and the second air chamber 4, and the connecting channel 5 is arranged in the channel member 7, one end of the channel member 7 is connected to the center of the first air chamber 3, and the other end is connected to the center of the second air chamber 4, so that the circulation space 104 is arranged around the channel member 7. Through the above-mentioned structural setting, the first air chamber and the second air chamber are distributed on both sides, and then connected by the channel member (connecting channel), and the existence of the circulation space is more conducive to the heat dissipation of the first air chamber, the second air chamber and the channel member, so that the structural layout of the hair trimmer is more reasonable. Among them, a part of the channel member can be integrally formed with the first air chamber, and another part of the channel member can be integrally formed with the second air chamber, and a part of the channel member is connected to another distribution to form a complete channel member. Of course, the specific structure of the above-mentioned channel member is not absolutely limited, but only serves as a preferred embodiment of the patent scheme.

[0033] In this embodiment, an air inlet channel 8 is further provided in the channel member 7, one end of the air inlet channel 8 is connected to the air inlet port 31 of the first air chamber, and the other end is formed as a communication port 81, and the communication port 81 is exposed to the circulation space 104. Specifically, the air inlet channel is a curved channel with a simple structure and reasonable design.

[0034] Furthermore, the air duct structure also includes an air guide hose 2, which is connected to the connecting port 81. The air guide hose 2 is arranged around the channel member 7 in the circulation space 104, and the first air chamber 3 and the second air chamber 4 clamp the air guide hose 2 on both sides of the air guide hose 2. Through the above-mentioned structural arrangement, a connecting port can be formed at the channel member, so that the air guide hose can be connected to the circulation space. On the one hand, the air guide hose can be stored around the channel member, and the structural space of the hair trimmer can be fully utilized, which is a clever design; on the other hand, placing the air guide hose in the circulation space is also conducive to the heat dissipation of the air guide hose.

[0035] In this embodiment, the first air chamber 3 is provided with a first connecting port 32, one end of the connecting channel 5 is connected to the first connecting port 32, and the air inlet 31 is staggered with the first connecting port 32. In this way, the airflow entering the first air chamber through the air inlet will not directly flow into the first connecting port, so that the flow path of the airflow can be extended, that is, the path for the noise to propagate to the outside can be extended, and the noise reduction effect can be further improved.

[0036] Furthermore, an air guide plate 33 is provided in the first air chamber 3, one end of the air guide plate 33 is connected to the inner wall of the first air chamber 3, and the other end is a suspended end 34 for shielding the air inlet 31, and a gap is provided between the other end of the air guide plate 33 and the inner wall of the first air chamber 3 to form a flow gap 35, and the flow gap 35 is not provided toward the first connecting port 32. In this way, the airflow can flow as much as possible in the first air chamber, that is, the flow path of the airflow can be extended, which also plays a role in further improving the noise reduction effect.

[0037] In this embodiment, the first connecting port 32 is provided with a filter device 9, and the filter device 9 is used to filter the airflow from the first air chamber 3 to the connecting channel 5, so that the first air chamber 3 is formed into a hair collection chamber. By setting the filter device, pet hair and other debris can be effectively collected in the first air chamber, so as to facilitate the cleaning of the hair trimmer. Specifically, the first air chamber can be disassembled from the main unit, which is more convenient for cleaning the collected hair. Among them, the disassembly structure of the first air chamber can be a snap-on fastening method, etc., which is not specifically limited here. At the same time, in the above structure, it can also be ensured that debris will not enter the first connecting port, that is, it will not enter the suction device, thereby forming an effective protection for the suction device, making the design of the hair trimmer more reasonable.

[0038] The filter device 9 is also detachable. Specifically, an annular mounting boss 36 is provided on the inner wall of the first air chamber. The mounting boss is arranged around the first connecting port, and a buckle 37 is provided on the inner wall of the mounting boss. An L-shaped slot 91 is provided on the outer wall of the filter device. The filter device is clamped in the buckle of the mounting boss with its L-shaped slot to realize the detachable installation of the filter device on the first connecting port. The structure is simple and convenient for disassembly and cleaning. Further, the filter device can specifically include a first layer of mesh filtration, a second layer of sponge filtration, and a third layer of filter element filtration to filter pet hair, especially fine debris.

[0039] In this embodiment, the second air chamber 4 is provided with a second communication port 42, the other end of the communication channel 5 is connected to the second communication port 42, the suction device 6 in the second air chamber 4 is placed in the second communication port 42, and the first exhaust port 41 and the second communication port 42 are staggered, so that the second air chamber 4 is formed into a heat dissipation cavity. In this way, the airflow entering the second air chamber through the communication channel will not flow directly to the first exhaust port, so that the flow path of the airflow can be extended, that is, the path for the noise to propagate to the outside can be extended, and the noise reduction effect can be further improved.

[0040] In this embodiment, the air duct structure further includes a locking screw 10. A plurality of mounting posts 43 are provided on the inner wall of the second air chamber 4, and the plurality of mounting posts 43 are arranged around the second communication port 42. A mounting screw hole 44 is provided on the mounting post 43. Correspondingly, the suction device 6 is provided with a mounting ring 61, and a plurality of mounting through holes 62 are provided on the mounting ring 61. The mounting ring 61 is sleeved on the mounting post 43 with its mounting through holes 62, and a damping sleeve 63 is provided between the mounting post 43 and the mounting through hole 62. The locking screw 10 is threadedly connected to the mounting screw hole 44 to lock and fix the mounting ring 61 to the mounting post 43. Through the above structural arrangement, the suction device can be installed in the second air chamber and placed in the second communication port, so that the suction device can suck more efficiently, and the structural design is more reasonable. Moreover, both ends of the damping sleeve extend out to form covering portions 64 for respectively covering both side surfaces of the mounting ring, further improving the damping effect. Among them, the suction device can specifically be a suction motor. And the circuit board 65 for controlling the motor can be arranged at the rear end of the motor, so that the circuit board can be arranged in the air duct, effectively dissipating heat from the circuit board, with a simple structure and reasonable design.

[0041] In this embodiment, the air duct structure further includes a cover 101. The cover 101 covers the suction device 6. The cover 101 is provided with a second exhaust port 102, and the second exhaust port 102 is arranged towards one side of the cover 101. The first exhaust port 41 is located on the other side of the cover 101. Through the above structural arrangement, on the one hand, the suction device can be covered by the cover to reduce the noise generated by the suction device. And, in cooperation with the setting of the second exhaust port, the normal flow of air and the effective heat dissipation of the suction device are realized. At the same time, since the second exhaust port is arranged towards one side of the cover and the first exhaust port is located on the other side of the cover, the air flow can flow more in the second air chamber as much as possible, that is, the flow path of the air flow is extended, which also plays a role in further improving the noise reduction effect. Among them, electronic components 103 of the grooming device can also be arranged in the second air chamber at the second exhaust port, so as to effectively dissipate heat from the electronic components, effectively realizing the function of the second air chamber as a heat dissipation chamber.

[0042] Moreover, the first exhaust port 41 is opened on the side wall of the second air chamber 4 and faces the circulation space 104. In this way, the air flow after passing through the air duct can be discharged into the circulation space through the first exhaust port, further promoting the air flow in the circulation space, thereby improving the heat dissipation effect.

[0043] In summary, in the air duct structure of the grooming device of the present utility model, the air guiding hose, the communication port, the air intake channel, the air intake port, the flow gap, the first air chamber, the first communication port, the communication channel, the second communication port, the cover body, the second exhaust port, the second air chamber, and the first exhaust port are connected in sequence to form a suction air duct. Specifically, the suction air duct starts from the flow space (communication port) and ends at the flow space (first exhaust port), achieving a secondary span on both sides of the grooming device main body; moreover, with the arrangement of components such as the air guiding plate and the cover body, a reasonable and effective layout is realized within the limited structural space of the grooming device, enabling both the intake part and the exhaust part of the suction air duct to be effectively extended, and the suction air duct to be more tortuous, thereby achieving a good noise reduction effect. Also, it is beneficial to the miniaturization design of the grooming device. At the same time, based on the design of the suction air duct, functions such as hair collection, air guiding hose storage, and heat dissipation are also incorporated, with a reasonable and ingenious design.
