Description
DUST REMOVAL KET AND DUST-PROOF DEVICEFIELD
[0001] The present application relates to dust proof technologies, and more particularly, to a dust removal kit and a dust-proof device.BACKGROUND
[0002] In practical applications, it is usually necessary for some devices to work in a dusty environment. Dust may accumulate in the ventilation channel of these devices and enter the inside of the devices, thus ventilation channel blockage and internal pollution may be caused, and it is not easy to clean. In forced air-cooling devices, the situation is more obvious and serious.
[0003] In an application, a cabinet with dust-proof function is provided to accommodate the device that needs to work in a dusty environment, but additional manufacturing and maintenance cleaning costs are increased. In another application, a dust-proof mesh is provided for the device to block dust, but the dust-proof mesh must be replaced periodically.
[0004] Therefore, those skilled in the art are committed to finding other dust-proof solutions.SUMMARY
[0005] According to examples of the present application, a dust removal kit and a dust-proof device are provided to achieve reliable dust-proof function and reduce costs.
[0006] The dust removal kit provided by examples of the present application includes: a dust-proof body with a dust-proof mesh; the shape of the dust-proof mesh matches with an area needing dust proof of a device, and the dust-proof body is to be elastically installed on the device; and at least one vibration module, constructed to be installed on the dust-proof body and able to generate vibration for driving the dust-proof body to vibrate together.
[0007] In an example, the dust removal kit further includes at least one mounting structure, each of which is constructed to be fixed on the device; and at least one elastic connecting structure, each of which is constructed to connect one mounting structure to the dust-proof body.
[0008] In an example, each vibration module comprises a centrifugal rotor motor or an electromagnetic vibrator, which is configured to generate the vibration according to a control signal.
[0009] In an example, each centrifugal rotor motor or electromagnetic vibrator is to receive the control signal from a control module in the device, and the control signal is generated by the control module according to preset dust removal interval and preset vibration duration, or according to a trigger signal.
[0010] In an example, the dust removal kit further includes a control module, configured to generate the control signal according to preset dust removal interval and preset vibration duration, or according to a trigger signal, and send the control signal to each centrifugal rotor motor or electromagnetic vibrator.
[0011] In an example, each mounting structure is fixed on the device by a press-in clip structure, or by a screw and nut structure.
[0012] In an example, each elastic connecting structure comprises: multiple flexible connection ribs.
[0013] In an example, each elastic connecting structure comprises: at least one spring.
[0014] The dust-proof device provided by examples of the present application includes: above-mentioned dust removal kit.
[0015] It can be seen from above technical solutions in examples of the application that because the vibration module may drive the dust-proof body to vibrate together with the vibration module, accumulated dust on the dust-proof body can be removed through vibration, and since the dust-proof body may be elastically installed on the device, the vibration will not affect the device itself. Therefore, technical solutions of present application can provide reliable dust-proof function. At the same time, since the manufacturing costs of the dust removal kit are lower than that of the cabinet with dust-proof function, and there are barely any cleaning costs and dust-proof mesh replacement costs, the costs are saved.
[0016] In addition, for devices with diverse application environments, it is not necessary to produce devices with different structures, and only the dust removal kit needs to be installed on devices that need to work in dusty environments.BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The reference numerals are as follows: DETAILED DESCRIPTION
[0022] In examples of the present application, it is considered that some devices, for example, a frequency inverter, not only need to be used in a clean air environment but also need to be suitable for an environment with dust due to the diversity of application environment. In order to obtain a reliable dust-proof function and reduce costs, a dust removal kit may be provided, and the dust removal kit can be installed on the device that needs to work in a dusty environment. In the examples, the dust removal kit may include at least one vibration module and a dust-proof body with a dust-proof mesh. The vibration module may be installed on the dust-proof body and able to generate vibration for driving the dust-proof body to vibrate together, so as to remove accumulated dust on the dust-proof body, especially on the dust-proof mesh. The dust-proof body may be elastically installed on the device, so that when the dust-proof body vibrates, the vibration will not affect the device itself. The shape of the dust-proof body may match with an area needing dust proof of a device.
[0023] When specifically implemented, the elastic installation can be achieved through various structural forms. Namely, the dust-proof body may be elastically installed on the device using various installation structures that can achieve elastic connections.
[0024] Reference will now be made in detail to examples, which are illustrated in accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. Also, the figures are illustrations of an example, in which assemblies shown in the figures are not necessarily essential for implementing the present application. In other instances, well-known assemblies, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the examples.
[0025] Figure 1 is a schematic diagram illustrating a frequency converter. As shown in figure, the air inlet area 11 is an area needing dustproof of the frequency converter 1.
[0026] Figures 2 to 4 are schematic diagrams illustrating a dust removal kit according to examples of the present application. Figure 2 is the main view, figure 3 is a schematic diagram illustrating the installation relationship of the mounting structure in figure 2, and figure 4 is a schematic diagram illustrating an electrical connector of a vibration module in figure 2.
[0027] As shown in figures 2 to 4, the dust removal kit 2 includes: a dust-proof body 21 with a dust-proof mesh 211, at least one vibration module 22 (two vibration modules 22 are taken as an example in figure 2) , at least one mounting structure 23 (four mounting structures 23 are taken as an example in figure 2) and at least one elastic connecting structure 24 (four elastic connecting structures 24 are taken as an example in figure 2) .
[0028] In an example, the shape of the dust-proof body 21 may match with an area needing dust proof of a device, for instance, the air inlet area of the frequency inverter. The dust-proof mesh 211 is used to block dust into the area needing dust proof.
[0029] There may be multiple implementation methods for the dust-proof body 21, for example, the dust-proof body 21 may be a dust-proof sheet, or a dust-proof cover, or any dust-proof shield. The structure of the dust-proof mesh 211 can be implemented in various forms, for instance, the dust-proof mesh 211may be circular-hole mesh or square-hole mesh.
[0030] Each vibration module 22 is constructed to be installed on the dust-proof body 21 and able to generate vibration for driving the dust-proof body 21 to vibrate together, so as to remove accumulated dust on the dust-proof body 21, especially on the dust-proof mesh 211.
[0031] In an example, each vibration module 22 may include a centrifugal rotor motor or an electromagnetic vibrator, which is configured to generate the vibration according to a control signal. In an example, the control signal may be generated by a control module in the device, and then sent to each centrifugal rotor motor or electromagnetic vibrator in the dust removal kit. In another example, the dust removal kit may further include a control module (not shown in figures 2 to 4) , which is configured to generate the control signal, and send the control signal to each centrifugal rotor motor or electromagnetic vibrator. In the example shown in figure 4, each centrifugal rotor motor or electromagnetic vibrator may receive the control signal and a power signal through an electrical connector 221.
[0032] In an example, the control signal may be generated according to preset dust removal interval and preset vibration duration, or be generated according to a trigger signal.
[0033] In another example, the vibration module 22 may be achieved by other structure.
[0034] Each mounting structure 23 is constructed to be fixed on the device, for instance, the frequency converter 1. Each mounting structure 23 may be fixed on the device using any fixing method. For example, in some examples, each mounting structure 23 may be fixed on the device by a press-in clip structure. There may be multiple implementation methods for the press-in clip structure, and one of them is shown in figure 3. In the example shown in figures 2 and 3, for each mounting structure 23, the mounting structure 23 includes a mounting hole 231, and the device includes a compressible elastic pin 12 with a limit structure matching with the mounting hole 231. In the example, the compressible elastic pin 12 can be inserted into the mounting hole and restrict the mounting hole to the limit structure when the mounting hole is aligned with the compressible elastic pin 12 and the mounting structure 23 is pressed. In another example, for each mounting structure 23, the mounting structure 23 may include a mounting column with a limit head, and the device may include an expandable elastic limit hole matching with the limit head. In this example, the limit head may be restricted to the expandable elastic limit hole when the limit head is aligned with the expandable elastic limit hole and is pressed.
[0035] In yet some examples, each mounting structure 23 may be fixed on the device by a screw and nut structure. In the examples, for each mounting structure 23, the mounting structure 23 may include a mounting hole, and the device may include a screw matching with the mounting hole. The mounting structure 23 may be fixed to the device by inserting the screws into the mounting holes and tightening the nuts onto the screws.
[0036] Each elastic connecting structure 24 is constructed to elastically connect one mounting structure 23 to the dust-proof body 21, so that the dust-proof body 21 can be elastically installed on the device, and when the dust-proof body 21 vibrates, the vibration will not affect the device itself.
[0037] There may be multiple implementation methods for the elastic connecting structure 24, and one of them is shown in figure 3, in the example in figure 3, the elastic connecting structure 24 includes multiple flexible connection ribs 241 (four flexible connection ribs 241 are taken as an example in figures 2 and 3) . In another example, the elastic connecting structure 24 may include at least one spring or other elastic element.
[0038] In the example shown in figures 2 to 4, the dust-proof body 21 may be elastically installed on the device via the at least one elastic connecting structure 24 and the at least one mounting structure 23.
[0039] Figure 5 is a schematic diagram illustrating a dust-proof device according to examples of the present application. As shown in figure 5, a dust-proof device is also provided by examples of the present application, and the dust-proof device includes above-mentioned dust removal kit 2 according to any one of the examples.
[0040] It can be seen from above technical solutions in examples of the application that because the vibration module may drive the dust-proof body to vibrate together with the vibration module, accumulated dust on the dust-proof body can be removed through vibration, and since the dust-proof body may be elastically installed on the device, the vibration will not affect the device itself. Therefore, technical solutions of present application can provide reliable dust-proof function. At the same time, since the manufacturing costs of the dust removal kit are lower than that of the cabinet with dust-proof function, and there are barely any cleaning costs and dust-proof mesh replacement costs, the costs are saved.
[0041] In addition, for devices with diverse application environments, it is not necessary to produce devices with different structures, and only the dust removal kit needs to be installed on devices that need to work in dusty environments.

It should also be understood that, "and / or" configured herein is intended to include any and all possible combinations of one or more of the associated listed items.
