[0074] Implementations of the present disclosure are further described in detail below with reference to the accompanying drawings and embodiments. The following detailed description of embodiments and the accompanying drawings are intended to exemplarily illustrate principles of the present disclosure, but are not intended to limit the scope of the present disclosure. The present disclosure may be implemented in many different forms and is not limited to the specific embodiments disclosed herein, and includes all technical solutions falling within the scope of the claims.

[0075] A blowing apparatus (for example, a portable fan) is generally used in some scenarios where air circulation is required to accelerate. Taking a hand-held fan in portable fans as an example, the hand-held fan has advantages of being small in size and easy to carry and use, so that the hand-held fan is widely used in environments where a space is narrow, personnel are dense and the hand-held fan is required to move at any time.

[0076] Accordingly, during use, the blowing apparatus is required to have a certain safety and relatively less noise.

[0077] However, in the related art, there are problems about safety and noise of the blowing apparatus caused by stability of installation of a motor. Still taking the hand-held fan as an example, in the related art, there is a situation that the installation of the motor is unstable. For example, the motor may move along a rotation axis of a rotating shaft, and / or the rest of the motor except the rotating shaft may rotate, which may affect a service life of the product and result in poor safety and high noise.

[0078] In order to at least partially solve the above-mentioned problems existed in the related art, the present disclosure provides a blowing apparatus. The blowing apparatus provided by the embodiments of the present disclosure will be described below with reference to FIG. 1 to FIG. 25.

[0079] It should be understood that, there may be many implementations of the present disclosure, and it should not be interpreted as being limited to the embodiments described herein. The embodiments described herein are merely intended to more thoroughly and clearly understand the present disclosure.Exemplary blowing apparatus

[0080] Referring to FIG. 1, FIG. 2, FIG. 3, FIG. 11, FIG. 12, and FIG. 13, an embodiment of the present disclosure provides a blowing apparatus 1000. The blowing apparatus 1000 includes a housing assembly 10, a limiting structure 20 and an air supply assembly 30. The housing assembly 10 has a first accommodating space 1131. The limiting structure 20 is disposed in the first accommodating space 1131 and has a second accommodating space 21. The air supply assembly 30 is configured to generate a first airflow. The air supply assembly 30 includes a motor 31 and a fan 32, and the fan 32 is in transmission connection with the motor 31. The air supply assembly 30 is located in the first accommodating space 1131, and the air supply assembly is at least partially disposed in the second accommodating space 21. At least in a direction of the first airflow, a movement of a portion of the air supply assembly 30 is limited by the limiting structure 20. For example, the movement of fixed portions (such as a fixed part of a shell 311 and a fixed part of the motor 31) of the air supply assembly 30 is limited. The fan 32 is disposed in the first accommodating space 1131, and is rotationally connected to the motor 31.

[0081] It should be noted that, in this specification, the movement may include rotation and / or displacement in a certain direction. The direction of the first airflow herein refers to a direction that the airflow is generated when the air supply assembly 30 is in operation. It may be understood that, the direction of the first airflow refers to a direction from the second housing 13 to the first housing 12 along an axis of the rotating shaft of the motor, and a direction opposite the first airflow refers to a direction from the first housing 12 to the second housing 13 along the axis of the rotating shaft of the motor.

[0082] Exemplarily, the motor 31 may include a shell 311, a rotating shaft 312 and other structures. The rotating shaft 312 may be rotationally connected to the fan 32, and during use, the fan 32 is driven by the rotation of the rotating shaft 312 to rotate to accelerate a speed of air flow. Herein, the other structures of the motor 31 may refer to conventional configuration of the motor, and will not be described in detail again.

[0083] Exemplarily, the blowing apparatus 1000 may also include a circuit board 53, a battery pack 55 and a control button 57. The circuit board 53 may be electrically connected to the motor 31 by a cable 54. For example, the first limiting member 22 may be provided with an opening 227, and the cable 54 passes through the opening 227 and is connected between the circuit board 53 and the motor 31. In some examples, referring to FIG. 14, the opening 227 may include a first opening 227a and a second opening 227b, the cable passes through one of the first opening 227a and the second opening 227b. Meanwhile, the opening 227 has a ventilation effect to dissipate heat when the blowing apparatus 1000 is in operation. The control button 57 may be in communication connection with the circuit board 53. The battery pack 55 may be electrically connected to the motor 31 and the circuit board 53. In some embodiments, the control button 57 may also be in communication connection with a separate circuit board. Herein, the specific connections and structures thereof may refer to conventional technologies in this field, and will not be described in detail again.

[0084] It should be noted that, the type and quantity of the control buttons may be set according to requirements of a specific application scenario, which is not limited in the present disclosure.

[0085] It should also be noted that, the battery pack 55 may be rechargeable or disposable. Correspondingly, the blowing apparatus 1000 may be provided with a charging port or a battery replacement structure.

[0086] According to the technical solution of the present disclosure, the limiting structure 20 is provided inside the housing assembly 10, and the limiting structure 20 may cooperate with other structures of the blowing apparatus 1000 to limit the movement of the motor 31 at least in the direction of the first airflow. In this way, during operation, the motor 31 may at least be prevented from moving along the rotation axis of the rotating shaft 312 in the direction of the first airflow, so that the installation stability of the motor 31 is improved, and thus the service life and safety of the blowing apparatus 1000 are improved. In addition, the air supply assembly 30 is disposed in the second accommodating space 21 of the limiting structure 20, so that the motor 31 may be separated from other parts of the blowing apparatus 1000 to a certain extent, and rotation of the non-rotating portions of the air supply assembly 30 is limited, and thus the noise caused by the movement of the motor 31 is reduced and collision with other adjacent parts is avoided.

[0087] Referring to FIG. 2, FIG. 3 and FIG. 13, the second accommodating space 21 may include a first sub-accommodating space 211, the limiting structure 20 may include a first limiting member 22, and the first limiting member 22 has the first sub-accommodating space 211. The air supply assembly 30 may be at least partially disposed in the first sub-accommodating space 211. Referring to FIG. 5 and FIG. 14, a first side of the first limiting member 22 is provided with a first step 221, and in the direction of the first airflow, the first step 221 abuts against an end of the air supply assembly 30 which is not provided with a fan.

[0088] In this way, the end of the air supply assembly 30 which is not provided with the fan abuts against the first step 221, and the air supply assembly 30 cooperates with other structures to prevent the movement of the motor 31 in the direction of the first airflow. Meanwhile, the air supply assembly 30 is at least partially located in the first sub-accommodating space 211, the rotation of the non-rotating part of the air supply assembly 30 is limited by the first limiting member 22 to a certain extent, thereby improving the stability of the motor 31, so that the operation noise of the blowing apparatus 1000 is reduced, and thus the use safety and comfort of the blowing apparatus 1000 is improved.

[0089] Referring to FIG. 2 to FIG. 5, the air supply assembly 30 may also include a shell 311, the shell 311 has a third accommodating space 3111, and the fan 32 is at least partially disposed in the third accommodating space 3111. The shell 311 is disposed in the first sub-accommodating space 211, and an end of the shell 311 abuts against the first step 221.

[0090] In this way, the first airflow may be guided through the shell 311 to ensure that the first airflow blows out in a certain direction and at a certain speed. Therefore, efficiency and performance of the blowing apparatus 1000 are improved. Moreover, during rotation of the fan 32, an air exhaust area of the shell 311 remains constant. In this way, the airflow may blow to a user more intensively and stably to provide a more comfortable and intensive cool air effect. In addition, the shell 311 may also function to absorb vibration from the fan 32 and the motor 31, so that wind noise is reduced, and thus the fan 32 is quieter during operation.

[0091] Herein, the structure of the shell 311 and the air guidance configuration thereof may refer to the conventional configuration in the field, and details are not described again.

[0092] Continuing referring to FIG. 2 to FIG. 5, in some embodiments, the air supply assembly 30 is disposed in the first sub-accommodation space 211, that is, the fan 32 and the motor 31 are disposed in the first sub-accommodation space 211. An inner circumferential surface of the first limiting member 22 is provided with at least one first groove part 222, and the at least one first groove part 222 is configured to increase a friction force between the shell 311 and the first limiting member 22. When an outer peripheral wall of the shell 311 abuts against the at least one of first groove part 222, the friction force between the shell 311 and the first limiting member 22 may be increased, so that the shell 311 is prevented from rotating.

[0093] The inner circumferential surface of the first limiting member 22 is provided with the first groove part 222, and when the shell 311 abuts against the first groove part 222, the friction force between the shell 311 and the inner circumferential surface of the first limiting member 22 may be increased to further limit the rotation of the shell 311, so that the rotation of the non-rotating portions of the motor 31 is limited, thereby improving the stability of the motor 31, and thus the stability and safety of the blowing apparatus 1000 is improved and the operating noise is reduced.

[0094] Referring to FIG. 5, the at least one first groove part 222 may include four first groove parts 222, and the four first groove parts 222 are uniformly distributed on the inner circumferential surface of the first limiting member 22. In this way, when the shell 311 abuts against the first limiting member 22, the shell 311 abuts against the first groove part 222 to achieve stable and uniform airflow guidance.

[0095] Each of the first groove parts 222 may include a plurality of first grooves 2221, the plurality of first grooves 2221 may extend in a circumferential direction of the first limiting member 22, so that the friction force between the shell 311 and the first l position limiting part 22 may be increased to the greatest extent, and thus the rotation of the shell 311 is limited more effectively.

In this way, the control button 57 may be disposed at the hand-held groove 1181 and be exposed from the first cover body 52, so that an overall structure of the blowing apparatus 1000 may be relatively compact and aesthetic.

[0109] Referring to FIG. 11 to FIG. 13, in some alternative implementations, the air supply assembly 30 is partially disposed in the first sub-accommodating space 211, and an end of the air supply assembly 30 which is provided with the fan 32 abuts against the housing assembly 10.

The second limiting member 23 is at least partially disposed in the first sub-accommodating space 211, for example, a portion of the second limiting member 23 is disposed in the first sub-accommodating space 211. A first end of the second limiting member 23 abuts against the first step 221, and a second end of the second limiting member 23 abuts against the housing assembly 10. The second accommodating space 21 may also include a second sub-accommodating space 212, and the second limiting member 23 has the second sub-accommodating space 212. The air supply assembly 30 may be at least partially disposed in the second sub-accommodating space 212.

[0111] Referring to FIG. 13, FIG. 15 and FIG. 16, the motor 31 may include a shell 311. The shell 311 has a third accommodating space 3111, and the fan 32 is at least partially disposed in the third accommodating space 3111. The shell 311 is disposed in the second sub-accommodating space 212, an outer peripheral surface of the housing 311 may abut against an inner circumferential surface of the second limiting member 23, the inner circumferential surface of the second limiting member 23 is provided with a second step 231 and a third step 232, and two end of the shell 311 abut against the second step 231 and the third step 232, respectively.

[0112] In this way, the movement of the housing 311 along the rotation axis of the rotating shaft 312 of the motor 31 may be prevented and the rotation of the shell 311 is limited through the second limiting member 23, so that the movement of the non-rotation portions of the motor 31 may be limited.

[0113] Continuing referring to FIG. 15 and FIG. 16, an outer peripheral surface of the second limiting member 23 is provided with at least one protruding point 223. For example, the at least one protruding point 233 may be a plurality of the protruding points 233, and the plurality of the protruding points 233 may be uniformly distributed on the outer peripheral surface of the second limiting member 23. The plurality of the protruding points 233 may abut against the housing assembly 10 and / or the first limiting member 22. The protruding point 233 may be hemispherical.

[0114] In this way, a friction force between the second limiting member 23 and the first limiting member 22 and a friction force between the second limiting member 23 and the housing assembly 10 may be increased through the protruding points 233. Therefore, the rotation of the shell 311 may be further limited, so that the movement of the non-rotation portions of the motor 31 is further limited. In addition, the plurality of protruding points 233 are uniformly distributed on the outer peripheral surface of the second limiting member 23, so that the friction force may be uniformly distributed.

[0115] It should be noted that, the protruding point 233 may also be designed in other shapes, such as ellipsoid, cone or square.

[0116] The second limiting member 23 may be made of rubber. In this way, the movement of the shell 311 is limited by the second limiting member 23 to limit the movement of the non-rotation portions of the motor 31, meanwhile, the second limiting member 23 has flexibility and may absorb vibration, so that noise may be isolated and absorbed to a certain extent, and thus the operation stability and safety of the blowing apparatus 1000 is further improved.

[0117] Continuing referring to FIG. 15 and FIG. 16, the first end of the second limiting member 23 is provided with a first air port 234, and a cross-sectional area of the first air port 234 close to the first step 221 is greater than a cross-sectional area of the first air port 234 close to the shell 311. For example, the first air port 234 may be tapered along an axial direction of the second limiting member 23, and the cross-sectional area of the first air port 234 is gradually increased in a direction close to the first end of the second limiting member 23. In this way, in a case that the first air port 234 is an air inlet, a cross-sectional area of the air inlet is gradually decreased, so that a thickness of this area is relatively thin, which not only facilitates abutting with the housing assembly 10 to seal to prevent air leakage, but also may guide and gather the air to gradually improve the intake air speed, and reduce noise.

[0118] The second end of the second limiting member 23 is provided with a second air port 235, and a cross-sectional area of the second air port 235 close to a abutting position between the second end of the second limiting member 23 and the housing assembly 10 is greater than a cross-sectional area of the second air port 235 close to the shell 311. For example, the second ventilation hole 235 may be tapered along the axial direction of the second limiting member 23, and the cross-sectional area of the second air port 235 is gradually increased in a direction close to the second end of the second limiting member 23. In this way, in a case that the second air port 235 is an air outlet, the cross-sectional area of the air outlet is gradually increased, so that a thickness of this area is relatively thin, which not only facilitates abutting with the housing assembly 10 to seal to prevents air leakage, but also may guide flow to ensure the distribution of the air and reduce noise.

[0119] It may be understood that, the first air port 234 and the shape of the second air port 235 may also be designed in other shapes, and it is not limited to being tapered.
