[0046] Further, the limiting piece 4 is a tightening belt, so that the electric wire 22 can be more orderly through the tightening belt wound on the electric wire 22, the wiring of the electric wire 22 is facilitated, and the reliability is improved.

[0049] In some embodiments of the utility model, as shown, Figures 6-10 The wire buckle 3 includes a buckle body 31. The buckle body 31 is connected with the volute 1 and is spaced apart from the volute 1 to form a through hole 311, the electric wire 22 passes through the through hole 311, and the end of the limiting piece 4 away from the body 21 abuts against the buckle body 31.

[0050] Thus, by connecting the buckle body 31 with the volute 1, the wire buckle 3 is arranged on the outer wall surface of the volute 1, and the part of the buckle body 31 is spaced apart from the volute 1 to form a through hole 311, the electric wire 22 passes through the through hole 311, and the end of the limiting piece 4 away from the body 21 abuts against the buckle body 31, so that the length of the electric wire 22 between the limiting piece 4 and the body 21 is limited by the cooperation of the limiting piece 4 and the buckle body 31, thereby effectively avoiding the resonance noise problem caused by the hard contact between the electric wire 22 and the volute 1, and reducing the noise of the fan assembly 100.

[0051] In some embodiments of the utility model, as shown in Figures 6-10 The wire buckle 3 further comprises a limiting rib 32.

[0052] Thus, by plugging part of the through hole 311 with the limiting rib 32, a narrow channel is formed, so that the electric wire 22 is slightly squeezed and fixed with a certain resistance when passing through the through hole 311, thereby limiting the excessive swing amplitude of the electric wire 22 while the length of the electric wire 22 between the limiting piece 4 and the body 21 is greater than the distance between the limiting piece 4 and the body 21, and further reducing the collision noise between the electric wire 22 and the volute 1.

It can be understood that, since the limiting rib 32 is located on the side of the buckle body 31 close to the body 21, by abutting the end of the limiting piece 4 close to the volute 1 against the limiting rib 32 and the end away from the volute 1 against the buckle body 31, the limiting piece 4 is inclined in the direction of the wire buckle 3 to the direction away from the wire buckle 3, so that the electric wire 22 between the limiting piece 4 and the body 21 forms an arc shape away from the volute 1, further avoiding the noise caused by the contact and collision between the electric wire 22 and the volute 1.

[0054] In some embodiments of the utility model, as shown in Figures 6-10 One end of the limiting rib 32 in the length direction is connected with the buckle body 31, and the other end is spaced apart from the buckle body 31. It can be understood that, since the limiting rib 32 plugs part of the through hole 311, by connecting one end of the limiting rib 32 in the length direction with the buckle body 31 and spacing the other end from the buckle body 31, a certain amount of space is formed between the limiting rib 32 and the buckle body 31, thereby preventing the electric wire 22 from being excessively squeezed when passing through the through hole 311, avoiding damage to the electric wire 22 during installation or vibration, reducing the risk of stress concentration of the buckle, and improving the reliability of the overall structure.

[0055] In some embodiments of the utility model, at least part of volute 1 and wire buckle 3 are integral. Therefore, the connection strength of wire buckle 3 and volute 1 is improved, and the assembly process of wire buckle 3 and volute 1 is reduced during the assembly of fan assembly 100, the assembly difficulty is reduced, and the assembly efficiency is improved.

[0056] In some embodiments of the utility model, as shown in Figures 5-10 Wire buckle 3 is arranged on the axial end surface of volute 1.

Therefore, by arranging the wire buckle 3 on the axial end surface of the volute 1, the wire buckle 3 is arranged closer to the wire outlet position of the body 21, thereby facilitating wiring, reducing bending and interference with other components, and improving reliability.

[0057] In some embodiments of the utility model, as shown in Figure 3 Fan assembly 100 further includes wind wheel 9. Wherein, wind wheel 9 is arranged in volute 1, the output shaft of body 21 is connected with wind wheel 9, for driving wind wheel 9 to rotate. It can be understood that volute 1 has an inlet and an outlet, and the body 21 drives the wind wheel 9 to rotate, so that the wind wheel 9 drives the airflow to enter the volute 1 from the inlet, and then flows out from the outlet, thereby realizing the flow of gas.

[0058] Optionally, wind wheel 9 is a centrifugal wind wheel 9, and the centrifugal wind wheel 9 axially inlets air and radially outlets air. The inlet is arranged on the axial end surface of volute 1 away from body 21, and the outlet is arranged on the circumferential wall surface of volute 1. The airflow axially enters volute 1 from the inlet, and then radially flows out of volute 1 from the outlet, which can minimize noise and ensure the stability of the operation of fan assembly 100.

Therefore, by fixing the body 21 to the axial end of the first shell 11, the output shaft of the body 21 extends along the axial direction of the volute 1, and the wire buckle 3 is arranged on the axial end surface of the first shell 11 and is an integral part of the first shell 11, thereby facilitating wiring and overall assembly, improving assembly efficiency and overall reliability.

[0060] In some embodiments, as shown in Figure 3As shown, the fan assembly 100 further comprises an air inlet frame 81, the air inlet frame 81 is provided with an air inlet, and the air inlet is provided with a baffle 82, and the air inlet is communicated with the cavity. Thus, the body 21 drives the fan wheel 9 to rotate, so that the fan wheel 9 drives the airflow to enter the cavity through the air inlet and the baffle 82, and then flows out from the outlet, thereby realizing the flow of the gas, and the baffle 82 further guides the airflow entering the cavity through the air inlet, and optimizes the flow path of the airflow.

[0061] Further, the first shell 11 and the second shell 12 are connected by fasteners, which can improve the reliability of the connection between the first shell 11 and the second shell 12, facilitate disassembly and assembly between the first shell 11 and the second shell 12, and shorten the assembly time of the fan assembly 100.

[0062] Further, as shown in the drawings, Figure 3 As shown, the fan assembly 100 further comprises an air outlet frame assembly 6, the air outlet frame assembly 6 is connected with the volute 1, the air outlet frame assembly 6 defines a flow channel therein, the outlet is communicated with the flow channel, and the air outlet frame assembly 6 is provided with an air outlet communicated with the flow channel. Thus, the flow direction of the airflow in the air outlet frame assembly 6 is from the outlet into the flow channel, and then flows out from the air outlet, thereby realizing the processing of the airflow entering the air outlet frame assembly 6.

[0064] The purification assembly can purify the airflow entering the air treatment module, so that the purified airflow is blown to the indoor to improve the air quality; the humidification assembly can humidify the airflow entering the air treatment module, so that the airflow with humidity is blown to the indoor to increase the water vapor content in the indoor and realize the humidification effect of the indoor; the heating assembly can heat or cool the airflow entering the air treatment module, so that the airflow with appropriate temperature is blown to the indoor to improve the use experience of the user; the sterilization assembly can sterilize the airflow entering the air treatment module, so that the airflow sterilized by killing bacteria is blown to the indoor to provide cleaner, healthier and more sanitary air for the user, and different use requirements of the user can be met.

[0065] In some embodiments of the present application, as shown in the drawings, Figure 5 and Figure 6As shown, the limiting piece 4 is inclined towards the direction away from the wire buckle 3 in the direction of the wire buckle 3 to the volute 1. Thus, through such a setting, the electric wire 22 located between the limiting piece 4 and the body 21 forms an arc shape away from the volute 1, further avoiding the noise caused by the contact collision between the electric wire 22 and the volute 1.
