The air inlet of the air duct corresponds to the side surface of the shell, and the side surface of the shell is arranged on the corresponding ventilation mesh of the air inlet of the air duct; the air outlet 213 of the air duct is located at the top end of the main body 21, and the housing is provided with an opening corresponding to the top end of the air outlet 213 of the air duct for blowing out the air in the air duct. Certainly, in other embodiments, an air guide member, such as the air guide grille 23, the second fan 22, and the like, is movably mounted at a position, corresponding to the air outlet 213, of the top end of the machine body 20, so that the air outlet direction of the machine body 20 can be adjusted as required.

It should be noted that all the directional terms (such as up/down, down/bottom, left, right, front, and rear) mentioned in the present specification refer to the state of the air treatment device 10 during operation. For example, the moving chassis 211 is located at the bottom end (or lower end) of the machine body 20, and the other end corresponding to the bottom end in the gravity direction is the top end of the machine body 20. The front end of the entire air treatment device 10 in the forward direction during operation is defined as the front end of the machine body 20, and the movement corresponding to the front end is the rear end.

In this embodiment, please refer to fig. 2 to 4, the top surface 221 of the machine body 20 is provided with a first acoustic opening 30, the voice sensor 40 is installed in the machine body 20 and is disposed corresponding to the first acoustic opening 30, and the voice sensor 40 receives a voice command through the first acoustic opening 30.

Specifically, the top surface 221 of the machine body 20 in this embodiment refers to a surface located at the top end of the machine body 20 and facing upward, the shape of the top surface 221 may be a plane, an inclined surface, an arc surface, and the like, the top surface 221 may be a surface of a housing of the machine body 20, or a surface of an air guide or a cover mounted at the top end of the machine body 20, and the top surface 221 may be defined according to the actual situation of the air treatment device 10 during specific design.

As shown in fig. 4, the voice sensor 40 is installed inside the body 20, so that the first acoustic hole 30 communicates with the inside of the body 20 to ensure smooth transmission of the sound signal to the voice sensor 40. In the present embodiment, when the first acoustic hole 30 penetrates through the top surface 221 of the body 20 along the gravity direction, the size, shape, number, arrangement when a plurality of first acoustic holes 30 are provided, and the like of the body 20 can be designed according to the need. For example, in some embodiments, the first acoustic opening 30 is a circular hole, which facilitates the processing of the first acoustic opening 30; and the diameter of the first acoustic opening 30 is not less than 1.5 mm, so that the situation that the first acoustic opening 30 is too small to cause inaccurate sound signal transmission and the situation that the first acoustic opening 30 is too large to affect the appearance of the air treatment device 10 can be avoided. In other embodiments, the first acoustic opening 30 may be provided in plural numbers to ensure that the voice sensor 40 can quickly detect the voice command, and thus ensure that the air treatment device 10 can quickly respond according to the voice command.

The voice sensor 40 of the present invention may be obtained by referring to an existing voice sensor structure, or by modifying and assembling the existing voice sensor. In this embodiment, after receiving the voice command from the user, the voice sensor 40 may feed the voice command back to the controller in the machine body 20, and then the controller controls the air treatment device 10 to perform a corresponding function or action according to the specific content of the voice command. For example, when the user needs to change the air outlet direction of the air treatment device 10 and blows towards the user himself, voice commands such as "face blow", "arm blow", etc. may be issued. After receiving the voice command, the voice sensor 40 in the machine body 20 feeds the voice command back to the controller in the machine body 20, and the controller controls the air guide to adjust the blowing direction, so that the air blown out by the air treatment device 10 is blown to the user, and the user requirements are met.

In summary, it can be understood that, in the air treatment device 10 of the present invention, the voice sensor 40 is disposed on the body 20, and the voice sensor 40 can receive a voice instruction from a user, so that the user can control the air treatment device 10 to perform a function or an action required by the user through voice, thereby improving the interaction performance of the air treatment device 10 and the interaction experience of the user.

In addition, compared with the first acoustic opening 30 arranged on the side surface or other positions of the air treatment device 10, the first acoustic opening 30 is arranged on the top surface 221 of the air treatment device 10, so that the voice signal of the user can be transmitted to the first acoustic opening 30 without obstruction, the voice sensor 40 can quickly receive the voice command, and the air treatment device 10 can quickly respond. And the intensity and the accuracy of the sound signal are also ensured, and the situation that the sound signal is distorted and weakened to be incapable of being transmitted to the voice sensor 40 due to the fact that the sound signal passes through an obstacle is avoided. For example, when the first acoustic hole 30 is disposed on the side of the body 20 and faces away from the acoustic hole when the user gives a voice command, the sound signal needs to pass through the entire housing of the air treatment device 10 and through various components with different thicknesses inside the air treatment device 10 to reach the sound sensor 40, and even some sound signals may not reach the sound sensor 40 due to more obstacles. And different obstacles have different sound signal transmission performance, when part of sound signals need to pass through more obstacles or pass through obstacles with poor sound transmission performance, and other sound signals do not need to pass through, the sound signals are distorted or have overlarge difference, so that the judgment of the sound sensor 40 and the controller on the sound signals is influenced. Therefore, when the first sound emission hole 30 is provided on the top surface 221 of the machine body 20, the receiving speed and accuracy of the corresponding sound signal by the sound sensor 40 are higher.

In an embodiment, please refer to fig. 3 and 8, the first acoustic opening 30 has at least two, such as two, three, four, six, etc., and the at least two first acoustic openings 30 are distributed in a ring shape; the voice sensor 40 includes at least two microphones 41, and each of the microphones 41 is disposed corresponding to one of the first acoustic holes 30. That is, the microphones 41 on the voice sensor 40 are also distributed in a ring shape, so that the direction and distance of the sound source can be calculated by the voice enhancement algorithm of the microphone 41 array, and further, the function or action required by the user can be better executed.

In addition, in the present embodiment, the voice sensor 40 calculates the direction and distance of the sound source by the voice enhancement algorithm of the microphone 41 array, mainly based on the time difference of the sound signal transmitted to each microphone 41. Therefore, it can be understood that when the first acoustic opening 30 is disposed on the top surface 221 of the main body 21, the acoustic signal can directly pass through the air to the first acoustic opening 30 without passing through other obstacles, thereby avoiding the situation that the time difference is not accurate enough when passing through obstacles of different materials or quantities between the acoustic signals, and ensuring the accurate judgment of the acoustic source by the voice sensor 40.

In an embodiment, referring to fig. 1 to fig. 3, the body 20 includes a main body 21 mounted with a first fan (not shown) and a second fan 22 mounted on the main body 21, the main body 21 includes the above-mentioned movable chassis 211 and a functional module 212, an air outlet 213 is disposed at a top end of the main body 21, and the air outlet 213 is an air outlet of the air duct and is disposed upward. The second fan 22 is movably installed at the air outlet 213, and is provided with an air guiding opening 223 communicated with the air outlet 213, so that the air blown out from the air outlet 213 can be blown out of the machine body 20 through the air guiding opening 223. So alright change the air-out direction through changing the state or the position of second fan 22, for example through rotate, the inclination of wobbling mode adjustment second fan 22, or through the position that slides, the mode of removal change second fan 22, and then change the air-out direction.

Specifically, in this embodiment, the air outlet direction of the second fan 22 is changed by rotating, the second fan 22 has different states because it can rotate, and taking the state when the second fan 22 is horizontally disposed as an example, the upper surface of the second fan 22 is the top surface 221 of the machine body 20. The first acoustic port 30 extends through the entire second fan 22 from the top surface 221 of the second fan 22, and the voice sensor 40 is mounted on a side surface of the second fan 22 facing the air outlet 213 (i.e., on the mounting surface 222, as shown). It can be understood that when the first acoustic port 30 and the voice sensor 40 are both mounted on the movable second fan 22, the first acoustic port 30 and the voice sensor 40 can move together with the second fan 22, and a situation where the second fan 22 becomes an obstacle in front of the first acoustic port 30 after moving to a certain state is avoided in a situation where the first acoustic port 30 does not move with the second fan 22. The voice sensor 40 can quickly and accurately receive voice instructions no matter what state the second fan 22 at the top end of the machine body moves to.

When the voice sensor 40 is disposed close to the free side 225, no matter what angle the second fan 22 rotates, the voice sensor 40 and the first acoustic opening 30 can be located at the top end of the whole air treatment device 10, and it is avoided that the first acoustic opening 30 and the voice sensor 40 are located at a low position which may be blocked by an obstacle after the second fan 22 rotates. This ensures that the voice sensor 40 is always in a position to quickly and accurately receive voice commands.

As to the specific manner of rotationally connecting the second fan 22 with the main body 21 through the connecting side 224 thereof, a rotating shaft may be connected to the connecting side 224, and two ends of the rotating shaft are rotationally connected to the main body 21. Or the main body 21 may be provided with a rotating shaft, and the second fan 22 is provided with two opposite bearing holes, and the two bearing holes are rotatably connected with two ends of the rotating shaft. Alternatively, the connecting side 224 and the main body 21 may be rotatably connected by a third connecting member, which may be designed according to actual situations.
