Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to an exhaust structure for a cleaning device and the cleaning device itself. Background Technology

[0002] A cleaning device requiring a relatively enclosed cleaning environment typically includes a chamber within which materials are cleaned. In related technologies, this chamber has perforations to allow exhaust gases generated during the cleaning process to escape. Because these exhaust gases may carry a large amount of particulate matter, they need to be collected and treated before being released to the outside or other devices. However, during exhaust and collection, the airflow pressure causes it to circulate back into the chamber, leading to secondary contamination of the materials within the chamber. This results in low cleaning efficiency and difficulty in achieving a high level of cleanliness.

[0003] Therefore, there is an urgent need for an exhaust structure for cleaning equipment that can improve cleaning efficiency and effectiveness. Utility Model Content

[0004] This application provides an exhaust structure for a cleaning device and a cleaning device in general, which can improve cleaning efficiency and cleaning effect.

[0005] In a first aspect, the present application provides an exhaust structure for a cleaning device, comprising: a cavity wall with an exhaust hole disposed in a cavity of the device, the cavity being used to provide a sealed cleaning environment, the cavity wall being used to discharge waste gas generated during the cleaning process through the exhaust hole, and an exhaust valve being disposed on the side of the cavity wall where the waste gas is discharged, the exhaust valve being used to control whether the cavity wall discharges waste gas;

[0006] The cavity wall contains multiple layers of parallel exhaust plates, and each exhaust plate has an exhaust hole.

[0007] At least one support member is provided between the exhaust plates, and the support member is used to form an exhaust space between the exhaust plates.

[0008] Optionally, the cavity wall has an assembly area for installing a cleaning assembly; the position of the at least one support between the exhaust plates corresponds to that in the assembly area.

[0009] Optionally, the cavity wall further includes a support frame, which contacts the outermost exhaust plate and supports it. The outermost exhaust plate is the exhaust plate closest to the waste gas recovery device. The support frame is used to create a waste gas recovery space between the cavity wall and the waste gas recovery device, which is used to collect the waste gas discharged from the exhaust port.

[0010] Optionally, the cavity wall is a square plane, the assembly area is a rectangular area, and the support frame includes a first sub-support frame and a second sub-support frame; the contact surface between the first sub-support frame and the outermost exhaust plate is provided with a first support frame air hole that coincides with the exhaust hole of the outermost exhaust plate; the contact surface between the second sub-support frame and the outermost exhaust plate is provided with a second support frame air hole that coincides with the exhaust hole of the outermost exhaust plate; the first sub-support frame and the second sub-support frame are respectively disposed at the two short side ends of the rectangular area.

[0011] Optionally, the cavity wall includes two layers of exhaust plates.

[0012] Optionally, the waste gas recovery device includes a gas collection component and a waste gas recovery pipe. The gas collection component includes a first pair of interfaces and a second pair of interfaces. The first pair of interfaces is connected to the cavity wall, and the second pair of interfaces is connected to the waste gas recovery pipe. The gas collection component guides the waste gas collected by the first pair of interfaces to the second pair of interfaces, and the diameter of the gas collection component gradually decreases along the airflow direction.

[0013] Optionally, the vertical projection of other exhaust plates in the multi-layered exhaust plates falls within the outermost exhaust plate, and the vertical direction is perpendicular to the plane where the exhaust plate is located.

[0014] Secondly, embodiments of this application provide a cleaning device, including an exhaust structure as described in any of the first aspects above.

[0015] The beneficial effects of this application are:

[0016] The exhaust structure in this embodiment includes a cavity wall with exhaust holes disposed within the equipment cavity. An exhaust valve is provided on the exhaust gas discharge side of the cavity wall. When it is necessary to discharge the exhaust gas generated during the cleaning process, the cavity wall is controlled to discharge the exhaust gas. The cavity wall contains multiple layers of parallel exhaust plates, and at least one support member is provided between the exhaust plates to form an exhaust space. In this way, the exhaust space can form a gas flow space. During the cycle when the exhaust valve is not open, the airflow can flow between the multiple layers of parallel exhaust plates without returning to the equipment cavity, causing dirt particles to fall on the material surface and causing material contamination. This improves both the cleanliness and the exhaust efficiency. It can solve the problem of poor cleaning effect caused by airflow reversal in related technologies.

[0017] These or other implementations of this application will become clearer and easier to understand in the following description of the embodiments. Attached Figure Description

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0021] Figure 3 This is a schematic diagram of another cavity wall structure provided in the embodiments of this application. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] It should be noted that in the description of this application, "at least one" refers to one or more, where "multiple" refers to two or more. Therefore, in the embodiments of the present invention, "multiple" can also be understood as "at least two". Furthermore, it should be understood that in the description of this application, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance, nor as indicating or implying order.

[0024] Figure 1 An exhaust structure for a cleaning device provided in an embodiment of this application, such as Figure 1 As shown, it includes: a cavity wall 101 with an exhaust port 102 disposed in the equipment cavity 100. The equipment cavity 100 is used to provide a sealed cleaning environment. The cavity wall 101 is used to discharge the exhaust gas generated during the cleaning process through the exhaust port 102. An exhaust valve 103 (not shown in the figure) is provided on the exhaust gas discharge side of the cavity wall 101. The exhaust valve 103 is used to control whether the cavity wall 101 discharges exhaust gas.

[0025] The cavity wall 101 includes multiple layers of parallel exhaust plates 104, and each exhaust plate is provided with an exhaust hole 102.

[0026] At least one support member 105 is provided between the exhaust plates 104, and the support member 105 is used to form an exhaust space between the exhaust plates 104.

[0027] In one embodiment, a cavity wall with an exhaust hole is provided on any cavity wall of the equipment cavity. The exhaust structure is suitable for providing a sealed cleaning environment for the equipment cavity. The exhaust structure serves as the cavity wall of the equipment cavity to realize the gas discharge function.

[0028] In one embodiment, the sealed cleaning environment is a relatively sealed cleaning environment, such as a cleaning airflow (e.g., dry ice particle airflow) inside the equipment cavity. If the air pressure inside the equipment cavity rises rapidly, the exhaust valve will detect that the air pressure exceeds the set pressure threshold and open the exhaust valve, so that the gas inside the equipment cavity can be discharged through the exhaust port.

[0029] In one embodiment, if the equipment cavity is also connected to an air outlet device, the gas from the air outlet device is injected into the equipment cavity, and the injected gas and the cleaning airflow are discharged through the exhaust port when the exhaust valve is opened.

[0030] In one embodiment, before the exhaust valve opens, the cleaning airflow is sprayed onto the material surface to clean it. The strong force of this cleaning airflow causes dirt particles detached from the material surface within the equipment cavity to rotate and float within the cavity, settling in corners and onto the material surface. This contaminates the clean cleaning environment of the equipment cavity and causes secondary contamination of the material, resulting in poor material cleaning. However, by providing at least one support member 105 between the exhaust plates 104, creating an exhaust space between them, most of the airflow carrying dirt particles will circulate within this space under the impact of the cleaning airflow. This prevents contamination of the equipment cavity environment and the material, improving the overall cleanliness of the material.

[0031] In one embodiment, a plurality of support members 105 are provided between the exhaust plates 104, and the plurality of support members 105 are evenly arranged in the planar space between the exhaust plates to achieve the structural stability of the exhaust space.

[0032] In one embodiment, when viewed perpendicular to the plane of the exhaust plates, the exhaust holes on the plurality of exhaust plates 104 are in the same position. That is, when projected onto adjacent exhaust plates in the direction perpendicular to the plane of the exhaust plates, the exhaust holes on the plurality of exhaust plates 104 are in the same position.

[0033] In one embodiment, the cavity wall includes two layers of exhaust plates, such as Figure 1 The exhaust plates shown are two layers, but they can also be three or four layers. The number of exhaust plate layers can be set according to relevant parameters such as airflow pressure and exhaust cycle length.

[0034] In one embodiment, the shape, size, and height of the support member can be specifically set as needed, and no specific limitations are imposed here. Figure 1 The support shown is a cuboid, but it can also be a cylinder or other shapes. The height mentioned is the height of the side that supports the adjacent exhaust plates to form an exhaust space.

[0035] Based on the above Figure 1 In the exhaust structure, this application embodiment provides a cavity wall, such as Figure 2 As shown, the cavity wall 200 has an assembly area 201 for mounting the cleaning assembly 202;

[0036] At least one support member 203 is positioned between the exhaust plates 204 in the assembly area 201.

[0037] In one embodiment, a cleaning assembly is disposed in the assembly area of ​​the cavity wall with vent holes to perform a cleaning operation. Multiple supports can be evenly distributed in the assembly area, and the supports are arranged according to the structural requirements of the assembly area. In this way, in addition to supporting the vent plate to form an vent space, the supports can also provide stable support for the cleaning assembly, thereby optimizing the structural strength of the cavity wall in the assembly area.

[0038] In one embodiment, the cleaning assembly may consist of a cleaning fixture and a spray gun. The cleaning fixture may be a three-axis module, a multi-axis module, or a robotic arm, etc., which holds the spray gun. Alternatively, it may be a cleaning assembly that integrates a robotic arm and a spray gun. The specific configuration and structure of the cleaning assembly are not limited here.

[0039] In one embodiment, the cleaning assembly may also include material conveying and fixing devices.

[0040] In one embodiment, between adjacent exhaust plates, the planar area of ​​the exhaust plate closer to the cleaning assembly can be smaller than the planar area of ​​the exhaust plate relatively farther away from the cleaning assembly, such as... Figure 2 As shown, the planar area of ​​the upper exhaust plate (the exhaust plate closer to the cleaning component) can be smaller than the planar area of ​​the lower exhaust plate (the exhaust plate relatively farther away from the cleaning component).

[0041] In one embodiment, the area of ​​the exhaust plate with the smallest planar area is larger than the assembly area, and the aforementioned planar area includes the area of ​​the plane of the exhaust plate occupied by the exhaust hole.

[0042] Based on the above Figure 2 In the cavity wall structure, this application provides yet another cavity wall structure, such as... Figure 3As shown, the cavity wall 300 also includes a support frame 301, which contacts the outermost exhaust plate 302 and supports the outermost exhaust plate 302. The outermost exhaust plate 302 is the exhaust plate closest to the waste gas recovery device 303.

[0043] The support frame 301 is used to form a waste gas recovery space between the cavity wall 300 and the waste gas recovery device 303, which is used to collect the waste gas discharged from the exhaust port.

[0044] In one embodiment, the support frame can support the outermost exhaust plate 302 and the waste gas recovery device 303 to form a waste gas recovery space. During waste gas recovery, the waste gas will not swirl back to the exhaust plate or even into the equipment cavity due to impacting the waste gas recovery device 303. This effectively ensures that the exhaust plate maintains a relatively clean exhaust environment and that the equipment cavity maintains a clean cleaning environment, thereby achieving the goal of Class 100 cleanliness.

[0045] In one embodiment, Figure 3 The exhaust gas recovery device 303 shown is only an illustration. It can be funnel-shaped or multiple hole-shaped exhaust gas recovery sub-devices, which are respectively connected to different areas of the outermost exhaust plate, etc. There are no specific restrictions on the structure and setting of the exhaust gas recovery device here, and it can be set according to needs.

[0046] In one embodiment, the support frame can be an I-shaped or perforated multi-faceted column. The exhaust holes on the surface of the support frame that contacts the outermost exhaust plate coincide with the exhaust holes on the outermost exhaust plate. Exhaust holes are provided on the first surface of the support frame that contacts the outermost exhaust plate; other surfaces can also have exhaust holes. This ensures that airflow can pass smoothly through the support frame. Alternatively, the support frame can be installed along the edge of the cavity wall, or both along the edge of the cavity wall and at least one support frame can be installed at the center of the cavity wall to ensure the durability of the cavity wall. There are no specific limitations on the shape, structure, or installation method of the support frame; it can be configured as needed.

[0047] The aforementioned support frame can form a waste gas recovery space and enhance the overall structural strength of the cavity wall. The position of the support frame and the exhaust port of the cavity wall are coordinated. The installation of the support frame improves the durability of the cavity wall in the cleaning environment. The support frame can be customized according to the specific dimensions of the equipment cavity, and the material selection of the support frame can be matched with the material of the cavity wall to ensure the stability of the overall structure.

[0048] Based on the above Figure 3 The cavity wall structure provided in this application embodiment is a square plane, the assembly area is a rectangular area, and the support frame includes a first sub-support frame and a second sub-support frame.

[0049] The contact surface between the first sub-support frame and the outermost exhaust plate is provided with a first support frame air hole that coincides with the exhaust hole of the outermost exhaust plate.

[0050] The contact surface between the second sub-support frame and the outermost exhaust plate is provided with a second support frame air hole that coincides with the exhaust hole of the outermost exhaust plate.

[0051] The first and second sub-support frames are respectively located at the ends of the two short sides of the rectangular area.

[0052] In one embodiment, such as Figure 3 As shown, Figure 3 (b) The left support frame 301 and the right support frame 301 can be regarded as the first sub-support frame and the second sub-support frame, respectively. These two support frames are located near the two short sides of the outermost exhaust plate of the cavity wall and on the two short sides of the assembly area of ​​the rectangular area. This can form a waste gas recovery space, provide good support for the cavity wall, and share the pressure of the cleaning components on the cavity wall. This can save support frame material and improve the durability of the cavity wall. Moreover, with this arrangement, the support frames will not obstruct the airflow of waste gas recovery, ensuring the waste gas recovery efficiency and the cleanliness of the equipment cavity and exhaust plate.

[0053] In one embodiment, the contact surface between the first sub-support frame and the outermost exhaust plate is provided with a first support frame air hole that coincides with the exhaust hole of the outermost exhaust plate; the contact surface between the second sub-support frame and the outermost exhaust plate is provided with a second support frame air hole that coincides with the exhaust hole of the outermost exhaust plate, so that the airflow can be smoothly discharged from the exhaust hole that coincides with the first sub-support frame and the outermost exhaust plate, ensuring the exhaust efficiency and thus ensuring the cleanliness of the equipment cavity and the exhaust plate.

[0054] Based on the above Figure 1-3 This application provides a cavity wall structure, wherein the vertical projection of other exhaust plates in the multi-layer exhaust plates falls within the outermost exhaust plate, and the vertical direction is perpendicular to the plane where the exhaust plates are located. That is, between adjacent exhaust plates, the edge of the exhaust plate closer to the cleaning assembly is located within the edge of the exhaust plate farther from the cleaning assembly.

[0055] Based on the above Figure 1-3 This application provides a cleaning device comprising the structures and related embodiments described above. Figure 1-3 The exhaust structure of any one of the exhaust structures and the exhaust structure of its related embodiments.

[0056] It should be noted that the cleaning equipment and related embodiments illustrated in this application are only used to illustrate the solution. Changes in the shape of each component, the number of components, and the addition or subtraction of components related to conventional functions should all be within the scope of the claims of this application and their equivalents. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
