DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0031] See also Figure 1, the embodiment of the present application provides a casing module 100 and a fan device 1000 configured with the casing module 100, the fan device 1000 is used to promote the flow of air in the environment to reduce the body temperature of the user located on the air outlet side of the fan device 1000. The fan device 1000 in this embodiment includes a casing module 100 and an airflow generator, and the airflow generator is rotatably installed in the internal space of the casing module 100. After the fan device 1000 is connected to a power source, the airflow generator can rotate quickly to draw air and output airflow. In this embodiment, the airflow generator may include a wind wheel 200 with a shape similar to a column, and such fan devices 1000 are generally called tower fans. In other embodiments, the airflow generator may include a conventional impeller, and the impeller may be applied to a floor-standing fan device 1000 or a ceiling-mounted fan device 1000.

[0032] See also Figure 1 In this embodiment, the fan device 1000 further includes a driving device 300, and the driving device 300 includes a rotating driving member, such as a servo motor, an AC motor, etc. The rotating driving member is arranged inside the casing module 100, and is rotatably connected to the wind wheel 200 to drive the wind wheel 200 to rotate. Specifically, the wind wheel 200 is respectively provided with a rotating shaft 210 and a matching groove at both ends of its rotation axis, and the rotating shaft 210 is rotatably matched with the casing module 100, and the matching member is used for the output shaft of the rotating driving member to pass through and be connected to the output shaft in a transmission manner, so that the wind wheel 200 rotates under the drive of the rotating driving member. In some other embodiments, the wind wheel 200 can be provided with a rotating shaft 210 at both ends of its rotation axis, wherein the rotating shaft 210 corresponding to the output shaft is connected to the output shaft in a transmission manner through a coupling or the like.

[0033] See also Figure 1 In this embodiment, the housing module 100 may include a shell 110, and the shell 110 is generally a columnar structure. The structure of the shell 110 defines a housing space 111 for accommodating the above-mentioned components such as the wind wheel 200 and the rotating drive member. The shell 110 is provided with a vent 112, and the wind wheel 200 rotates in the accommodating space 111 so that the air near the fan device 1000 can be sucked into the accommodating space 111 and output in a state of fast airflow. It should be understood that the vent 112 in this embodiment includes an air inlet 1121 and an air outlet 1122, and the air is sucked into the accommodating space 111 through the air inlet 1121, and then output through the air outlet 1122 to ensure smooth air flow.

[0034] See also Figure 1, the housing module 100 in this embodiment may further include a protective grille 120, which is used to cover the vent 112. As can be seen from the foregoing, the vent 112 includes an air inlet 1121 and an air outlet 1122. Correspondingly, the protective grille 120 in this embodiment may also include an air inlet grille 121 and an air outlet grille 122. The air inlet grille 121 is installed on the housing 110 and covers the air inlet 1121 to prevent a person's hand from reaching into the accommodating space 111 through the air inlet 1121 and touching the rapidly rotating wind wheel 200, thereby preventing the user from being injured, and also preventing thread-like or belt-like objects from being entangled in the wind wheel 200, thereby preventing clothing or foreign objects from being sucked into the accommodating space 111. The air inlet grille 121 in this embodiment is detachably mounted on the housing 110, so that the air inlet grille 121 can be removed to clean the air inlet grille 121, or the components in the accommodation space 111 can be inspected or cleaned. Similarly, the air outlet grille 122 is mounted on the housing 110 and covers the air outlet 1122 to prevent a person's hand from reaching into the accommodation space 111 through the air inlet 1121 and touching the rapidly rotating wind wheel 200, thereby preventing the user from being injured and clothes or foreign objects from being entangled with the wind wheel 200. The air outlet grille 122 in this embodiment is detachably mounted on the housing 110, so that the air outlet grille 122 can be removed to clean the air outlet grille 122, or the components in the accommodation space 111 can be inspected or cleaned.

[0035] See also Figure 1 and Figure 2 In some embodiments, the housing module 100 may further include a brake assembly 130 corresponding to the air inlet grille 121, and the brake assembly 130 is installed in the accommodating space 111. When the air inlet grille 121 is disassembled, that is, when the air inlet grille 121 is in a disassembled state, the air inlet 1121 is exposed. The brake assembly 130 can fit with the rotating shaft 210 of the wind wheel 200, so that the brake assembly 130 and the rotating shaft 210 rub against each other to quickly stop the rotation of the rotating shaft 210 and the wind wheel 200, reduce the danger level of the wind wheel 200, reduce the danger level of disassembling the air inlet grille 121 and repairing the fan device 1000, and do not need to wait for a long time until the wind wheel 200 stops rotating, thereby improving work efficiency, and can also limit the rotation of the wind wheel 200 during the maintenance process to prevent the rotation of the wind wheel 200 from interfering with the maintenance work.

[0036] See also Figure 2 , Figure 3 and Figure 4After cleaning or maintenance, the air inlet grille 121 is reinstalled back into the housing 110, and the air inlet 1121 is covered by the air inlet grille 121, eliminating the potential safety hazard caused by the exposure of the air inlet 1121. At the same time, the air inlet grille 121 pushes the brake assembly 130 to separate the brake assembly 130 from the rotating shaft 210 of the wind wheel 200, so as to remove the rotation restriction of the brake assembly 130 on the rotating shaft 210 and the wind wheel 200. Specifically, the air inlet grille 121 includes a protective body and a pushing member connected to the protective body. In order to distinguish it from the structure of the air outlet grille 122 described later, in this embodiment, the protective body of the air inlet grille 121 is defined as the air inlet grille body 1211, and the pushing member of the air inlet grille 121 is defined as the air inlet pushing member 1212. When the air inlet grille 121 is installed on the shell 110, that is, when the air inlet grille 121 is in an assembled state, the air inlet grille body 1211 is connected to the shell 110 and covers the air inlet 1121, and the air inlet pushing component 1212 extends into the accommodating space 111 and pushes the brake assembly 130 to separate from the rotating shaft 210, so as to release the rotation restriction of the brake assembly 130 on the rotating shaft 210 and the wind wheel 200.

[0037] In some other embodiments, the housing module 100 is also provided with a brake assembly 130 as described above corresponding to the air outlet grille 122. Figure 2 , Figure 3 and Figure 4 1 is a schematic diagram of the structure of the air inlet grille 121 and the brake assembly 130. The schematic diagram of the structure of the air outlet grille 122 and the brake assembly 130 can be referred to Figure 2 , Figure 3 and Figure 4 Specifically, when the air outlet grille 122 is disassembled, that is, when the air outlet grille 122 is in a disassembled state, the brake assembly 130 can fit with the rotating shaft 210 of the wind wheel 200, so that the brake assembly 130 and the rotating shaft 210 rub against each other, so as to quickly stop the rotation of the rotating shaft 210 and the wind wheel 200, reduce the danger level of the wind wheel 200, reduce the danger level of disassembling the air outlet grille 122 and repairing the fan device 1000, and do not need to wait for a long time until the wind wheel 200 stops rotating, thereby improving work efficiency, and can also limit the rotation of the wind wheel 200 during the maintenance process to prevent the rotation of the wind wheel 200 from interfering with the maintenance work.

[0038] After cleaning or maintenance, the air outlet grid 122 is reinstalled back to the housing 110, and the air outlet 1122 is covered by the air outlet grid 122, eliminating the safety hazard caused by the air outlet 1122 being exposed. At the same time, the air outlet grid 122 pushes the brake assembly 130 to separate the brake assembly 130 from the rotating shaft 210 of the wind wheel 200, so as to release the rotation restriction of the brake assembly 130 on the rotating shaft 210 and the wind wheel 200. Specifically, the air outlet grid 122 includes an air outlet grid body and an air outlet pushing component connected to the air outlet grid body. When the air outlet grid 122 is installed on the housing 110, that is, when the air outlet grid 122 is in an assembled state, the air outlet grid body is connected to the housing 110 and covers the air outlet 1122, and the air outlet pushing component extends into the accommodating space 111, and pushes the brake assembly 130 to separate from the rotating shaft 210, so as to release the rotation restriction of the brake assembly 130 on the rotating shaft 210 and the wind wheel 200.

[0039] In summary, when the protective grille 120 (the air inlet grille 121 or the air outlet grille 122) of the casing module 100 provided in the present embodiment is in a disassembled state, that is, when the vent 112 (the air inlet 1121 or the air outlet 1122) is in an exposed state, the brake assembly 130 can fit with the rotating shaft 210 of the wind wheel 200 to form a mutual friction relationship, and can stop the rotation of the wind wheel 200 in a short time, thereby avoiding safety hazards caused by the rapid rotation of the wind wheel 200, avoiding injuries to users caused by the rapid rotation of the wind wheel 200, avoiding entanglement of the wind wheel 200 with foreign objects and causing damage to the fan device 1000, and improving the efficiency of maintenance and cleaning work. When the protective grille 120 (the air inlet grille 121 or the air outlet grille 122) is restored to the assembled state, the pushing member (the air inlet pushing component 1212 or the air outlet pushing component) included in the protective grille 120 (the air inlet grille 121 or the air outlet grille 122) can push the brake assembly 130 to separate the brake assembly 130 from the rotating shaft 210, so as to release the rotation restriction of the brake assembly 130 on the wind wheel 200, so that the wind wheel 200 can rotate normally.

[0040] Next, the structures of the brake assembly 130 and the housing 110 will be described in detail.

[0041] See also Figure 3 and Figure 5In this embodiment, the brake assembly 130 may include an elastic connector 131 and a friction member 132. The elastic connector 131 is connected to the housing 110, and the friction member 132 is disposed on the elastic connector 131. The elastic connector 131 in this embodiment is a structure having a certain extension length, so that the friction member 132 can be transferred to the accommodating space 111 and correspond to the (outer peripheral side) of the rotating shaft 210 of the wind wheel 200. When the air inlet grille 121 is in an assembled state, the air inlet pushing component 1212 on the air inlet grille 121 can push the elastic connector 131 to separate the friction member 132 from the rotating shaft 210 of the wind wheel 200. After the fan device 1000 is powered off and the air inlet grille 121 is in a disassembled state, the friction member 132 fits with the rotating shaft 210 under the elastic recovery effect of the elastic connector 131, and the friction member 132 can produce friction with the rotating shaft 210, thereby hindering the rotation of the rotating shaft 210 and the wind wheel 200 until the wind wheel 200 stops rotating. In this embodiment, the material of the elastic connector 131 is not limited, and it is sufficient that the elastic connector 131 is elastic as a whole. For example, the elastic connector 131 in this embodiment can be a sheet structure or a rod structure made of a rigid material (such as steel, iron, copper, etc.) to enable the elastic connector 131 to have elastic deformation ability. In some other embodiments, the elastic connector 131 can be a structure with elastic deformation ability made of an elastic material (such as rubber, plastic, etc.).

[0042] See also Figure 5 and Figure 6 Specifically, the elastic connector 131 in this embodiment includes a connecting portion 1311 and an elastic portion 1312 connected to each other. The connecting portion 1311 is used to be fixedly connected to the housing 110 so that the elastic connector 131 is installed on the housing 110. The elastic portion 1312 extends toward the wind wheel 200 relative to the connecting portion 1311 and the housing 110 until the local structure of the elastic portion 1312 corresponds to the rotating shaft 210 of the wind wheel 200. The friction member 132 is arranged on the local structure corresponding to the elastic portion 1312 and the rotating shaft 210. When the air inlet grille 121 is in a disassembled state, the friction member 132 can be attached to the rotating shaft 210 of the wind wheel 200. When the air inlet grille 121 is in an assembled state, the elastic portion 1312 is pushed by the air inlet pushing component 1212 to deflect in a direction away from the rotating shaft 210, and at the same time drives the spatial position of the friction member 132 to change until the friction member 132 is separated from the rotating shaft 210.

[0043] See also Figure 6, this embodiment does not limit the structure of the elastic connector 131 and the structure of the elastic part 1312 and the connecting part 1311. In actual application scenarios, the structures of the elastic connector 131 and the housing 110 can cooperate with each other to achieve their respective functions. In some embodiments, the connecting part 1311 can be a plate-like or sheet-like structure, which is connected to the housing 110 by bonding or welding, and the elastic part 1312 can be a spring. In some embodiments, the elastic connector 131 is a spring structure, one end of the spring serves as the connecting part 1311 and is connected to the housing 110, and the spring structure itself serves as the elastic part 1312 in the above text. In this embodiment, the elastic connector 131 is an elastic metal sheet in the shape of a long strip. After being bent, one of the bent sections serves as the connecting section 1311 and is connected to the housing 110, and the other bent section serves as the elastic part 1312 and extends toward the wind wheel 200 relative to the housing 110.

[0044] See also Figure 5 and Figure 7 In this embodiment, the housing 110 may include a main body 113 and a mounting fitting 114. The main body 113 serves as the main body 113 structure of the fan device 1000 and defines the aforementioned accommodation space 111. The mounting fitting 114 in this embodiment is disposed near the side of the main body 113 facing the accommodation space 111 and is used to cooperate with the connecting portion 1311, so that the structure of the housing 110 and the structure of the elastic connecting member 131 are relatively simple. The mounting fitting 114 is connected to the main body 113, and a part of the structure of the mounting fitting 114 is spaced apart from the main body 113 to jointly define a mounting groove 1141, which is an open groove body, and the mounting groove 1141 is used for the connecting portion 1311 to pass through, so that the connecting portion 1311 (i.e., the elastic connecting member 131) is connected to the housing 110. Specifically, the mounting groove 1141 in this embodiment has two ports in its extension direction, and the connecting portion 1311 passes through the mounting groove 1141 through one of the ports and passes through the mounting groove 1141 through the other port. In some other embodiments, the connecting portion 1311 can pass through the mounting groove 1141 through one of the ports and be embedded in the mounting groove 1141. In this embodiment, the mounting groove 1141 can also be provided with only one port. In some other embodiments, a part of the structure of the mounting fitting 114 is spaced apart from the main body 113 to jointly define a structure similar to a through hole for the connecting portion 1311 to pass through. In some other embodiments, the position of the mounting fitting 114 on the main body 113 can also be selected according to the actual structure of the fan device 1000. In this embodiment, the mounting fitting 114 can be a block structure or a sheet structure, or other structures that can define the mounting groove 1141 with the main body 113.

[0045] In this embodiment, the housing module 100 further includes at least one fixing member (not shown in the figure). The fixing member can be sequentially arranged on the main body 113, the connecting portion 1311 and the mounting fitting 114 to fix the housing 110 and the elastic connecting member 131. This embodiment does not limit the type of the fixing member, for example, it can be a screw, a fixing pin, etc. In some embodiments, the spacing distance between the partial structure of the mounting fitting 114 and the main body 113 can be set to be smaller so as to clamp the connecting portion 1311.

[0046] See also Figure 5 and Figure 7 , the shell 110 in this embodiment may also include a resisting member 115, and the resisting member 115 is arranged on the side of the main body 113 facing the accommodating space 111. The resisting member 115 and the mounting fitting 114 are arranged in parallel. As can be seen from the foregoing, in this embodiment, the resisting member 115 corresponds to the port of the mounting groove 1141 for the connection part 1311 to pass through. Specifically, in the process of the connection part 1311 in this embodiment cooperating with the shell 110, the end of the connection part 1311 away from the elastic part 1312 first passes through the mounting groove 1141 through one of the ports of the mounting groove 1141, and then passes through the mounting groove 1141 through another port, and continues to move toward the resisting member 115 until it abuts against the resisting member 115, so as to indicate that the connection part 1311 is installed to the predetermined position, and the elastic connection part 131 is completed with the shell 110.

[0047] See also Figure 7 The abutting member 115 of this embodiment includes an abutting portion 1151 and a limiting portion 1152 connected to each other. The abutting portion 1151 is provided on the main body 113 and protrudes relative to the main body 113 to achieve the function of abutting with the connecting portion 1311 mentioned above. The limiting portion 1152 is located between the abutting portion 1151 and the mounting fitting 114, that is, the limiting portion 1152 extends relative to the abutting portion 1151 toward the mounting fitting 114. The limiting portion 1152 is used to limit the end of the connecting portion 1311 away from the elastic portion 1312. Specifically, the limiting portion 1152 is spaced apart from the main body 113 and defines a limiting groove 1153 for the connecting portion 1311 to pass through. Therefore, in the process of the connection part 1311 of the present embodiment cooperating with the housing 110, the end of the connection part 1311 away from the elastic part 1312 first passes through the installation slot 1141 through one of the ports of the installation slot 1141, then passes through the installation slot 1141 through the other port, then continues to move toward the limiting part 1152 and passes through the limiting slot 1153, and continues to move toward the abutting part 1151 until it abuts against the abutting part 1151. The limiting part 1152 can limit the end of the connection part 1311 away from the elastic part 1312 from tilting up and affecting the stability of the connection relationship between the elastic connector 131 and the housing 110.

[0048] See also Figure 6 and Figure 8 , the brake assembly 130 in this embodiment may also include a magnetic member 133, and the magnetic member 133 may include a permanent magnet or an electromagnet. As can be seen from the foregoing, the magnetic member 133 is arranged on one side of the elastic connecting member 131 (i.e., the elastic part 1312, and the elastic part 1312 is used uniformly hereinafter) and is opposite to the rotating shaft 210. The magnetic member 133 in this embodiment is arranged on the side of the elastic part 1312 away from the friction member 132 and the rotating shaft 210. In an actual application scenario, the rotating shaft 210 is a magnetic structure, such as an iron rotating shaft 210 or a steel rotating shaft 210. When the protective grid 120 is in a disassembled state, the elastic part 1312 drives the friction member 132 to move toward the rotating shaft 210 until the friction member 132 fits against the rotating shaft 210. The magnetic member 133 can be attracted to the rotating shaft 210 via the elastic part 1312 and the friction member 132 , which can ensure the fit between the friction member 132 and the rotating shaft 210 on the one hand, and increase the friction force between the friction member 132 and the rotating shaft 210 on the other hand, so as to further improve the braking efficiency of the friction member 132 , i.e. the brake assembly 130 .

[0049] See also Figure 3 and Figure 4 Next, the structure of the protective grille 120 and the matching relationship between the protective grille 120 and the elastic connecting member 131 are introduced by taking the air inlet grille 121 as an example. In this embodiment, the elastic part 1312 and the friction member 132 are arranged on the side of the rotating shaft 210 away from the air inlet 1121. In this embodiment, the air inlet pushing member 1212 of the air inlet grille 121 is generally a rod-shaped structure protruding from the air inlet grille body 1211. In the process of assembling the air inlet grille 121 to the housing 110, the air inlet pushing member 1212 extends into the accommodating space 111, and the air inlet pushing member 1212 first abuts against the elastic connecting member 131 (i.e., the elastic part 1312, hereinafter referred to as the elastic part 1312), and then pushes the elastic part 1312 to deflect in the direction away from the rotating shaft 210 until the friction member 132 is driven to separate from the rotating shaft 210, so as to release the rotation restriction of the rotating shaft 210 and the wind wheel 200 by the friction member 132. Therefore, in this embodiment, the air intake pushing component 1212 and the friction member 132 are located on the same side of the elastic portion 1312 .

[0050] In the above-mentioned embodiment in which the magnetic member 133 is provided, the air inlet pushing member 1212 and the friction member 132 can be respectively provided on opposite sides of the elastic member 1312, and a magnetic structure is provided on the pushing member. When the air inlet grille 121 is in an assembled state, the attraction of the magnetic structure to the magnetic member 133 can overcome the attraction of the rotating shaft 210 to the magnetic member 133 and the elastic force of the elastic member 1312, and the magnetic member 133 is attracted to the magnetic structure, so that the friction member 132 is separated from the rotating shaft 210. In the process of disassembling the air inlet grille 121, the magnetic member 133 is separated from the magnetic structure, and the friction member 132 moves toward the direction close to the rotating shaft 210 under the action of the magnetic member 133 or the elastic member until the friction member 132 is in contact with the rotating shaft 210.

[0051] See also Figure 8 In this embodiment, the friction member 132 is recessed on one side of the rotating shaft 210 to form a braking arc surface 1321, and the braking arc surface 1321 is used to fit with the outer peripheral surface of the rotating shaft 210 to increase the contact surface between the friction member 132 and the rotating shaft 210, and increase the friction between the friction member 132 and the rotating shaft 210. In some embodiments, a plurality of limit strips extending along the axial direction of the rotating shaft 210 are convexly provided on the braking arc surface 1321, and correspondingly, a plurality of grooves are also provided on the outer periphery of the rotating shaft 210, and the grooves are used to embed the limit strips to further improve the braking effect of the friction member 132.

[0052] In summary, when the protective grille 120 of the housing module 100 provided in this embodiment is in a disassembled state, that is, when the vent 112 is in an exposed state, the brake assembly 130 can fit with the rotating shaft 210 of the wind wheel 200 to form a mutual friction relationship, and can stop the rotation of the wind wheel 200 in a short time, so as to avoid the safety hazard caused by the rapid rotation of the wind wheel 200, avoid the rapid rotation of the wind wheel 200 to hurt the user, avoid the wind wheel 200 and foreign objects entangled to cause damage to the fan device 1000, and improve the efficiency of maintenance and cleaning work. When the protective grille 120 is restored to the assembled state, the pusher included in the protective grille 120 can push the brake assembly 130 to separate the brake assembly 130 from the rotating shaft 210, so as to release the rotation restriction of the brake assembly 130 on the wind wheel 200, so that the wind wheel 200 can rotate normally.
