Description

Technical Field

[0001] The present application relates to the technical field of range hood cleaning devices, and in particular to a range hood air suction hole cleaning device. Background Art

[0002] There are numerous drums on cigarette machine equipment, and these drums have different functions and play an important role in the cigarette production process. In order to ensure the adsorption of cigarettes, suction holes are usually opened on the drums. Negative pressure equipment is used to generate negative pressure at the suction holes, so that the cigarettes are adsorbed and fixed on the drums, which is convenient for various processing or transfer and transportation.

[0003] In some processing processes, cigarettes are cut, which will produce a lot of smoke foam. This kind of smoke foam has a certain viscosity. Some of the smoke foam will float into the suction holes of the drum wheel. After the smoke foam in the suction holes accumulates for a long time, it will easily lead to a decrease in the adsorption capacity of the suction holes, and even cause the suction holes to be blocked, thus affecting the normal production. Therefore, the drum wheel suction holes need to be cleaned regularly.

[0004] Currently, the commonly used cleaning method is high-pressure blowing, which directly uses a high-pressure air pipe to blow at the suction hole of the drum wheel to blow out the debris in the suction hole. Since the airflow intensity of the high-pressure air pipe will continue to decay in the air as the path increases, and the diameter of the suction hole is small and the diameter of the high-pressure air pipe is large, during blowing, the high-pressure air pipe cannot extend into the suction hole, making it difficult to blow away the attachments deep in the suction hole, resulting in poor blowing cleaning effect. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the related technology, the present application provides a range hood suction hole cleaning device, which can be extended into the suction hole for spray cleaning, shortening the distance between the high-pressure airflow and the attachment, ensuring the blowing intensity of the airflow, thereby improving the cleaning effect.

[0006] The present application provides a device for cleaning the air suction holes of a range hood, comprising an air duct, a reversing head, a fixed joint, a nozzle, a connecting head, and a holding assembly. The top of the air duct is connected to the reversing head, an air outlet duct is arranged on the reversing head, and a nozzle is installed on the end of the air outlet duct via a detachable fixed joint. A connecting head is installed at the bottom of the air duct, and the connecting head is connected to an external air supply device via a hose. A holding assembly is also installed on the air duct for easy operation.

[0007] Optionally, in some embodiments, a limiting ring is provided at the end of the nozzle, and the nozzle is clamped in the fixed joint through the limiting ring after passing through the fixed joint.

[0008] Optionally, in some embodiments, the air outlet pipe is processed with an external thread, and the fixed joint is correspondingly processed with an internal thread, and the limiting ring can be tightened by rotating the fixed joint, thereby fixing the nozzle at the air outlet pipe.

[0009] Optionally, in some embodiments, a sealing ring is provided between the contact surface between the air outlet pipe and the limiting ring.

[0010] Optionally, in some embodiments, the holding assembly includes a U-shaped buckle, a bolt, a nut, and a handle. The U-shaped buckle is clamped on the outer wall of the air duct. The bolt passes through the end of the U-shaped buckle and is threadedly connected to the nut. The U-shaped buckle can be used to tighten the air duct by rotating the nut to fix it. The U-shaped buckle is also fixed with a handle.

[0011] The technical solution provided by this application may have the following beneficial effects:

[0012] The present application uses a slender nozzle that can be extended into the suction hole of the drum wheel, thereby shortening the distance between the high-pressure airflow and the attachments, ensuring the blowing intensity of the airflow, facilitating the blowing and cleaning of attachments deep in the suction hole, ensuring the smoothness of the suction hole, and thus ensuring the normal production of the production line; and the nozzle is designed to be detachable, and nozzles of different lengths or diameters can be replaced according to the size of the drum wheel during cleaning, thereby ensuring the effect of the blowing and cleaning.

[0020] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0021] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0022] In the description of the present application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0024] See also Figure 1-3 The device for cleaning the air suction hole of a range hood comprises an air duct 1, a reversing head 2, a fixed joint 4, a nozzle 5, a connecting head 6, and a holding assembly 7. The top of the air duct 1 is connected to the reversing head 2 by threads, and the direction of the spraying airflow is changed by the reversing head 2. An air outlet duct 21 is arranged on the reversing head 2. The pipe wall of the air outlet duct 21 is processed with external threads, and the fixed joint 4 is processed with internal threads correspondingly. The air outlet duct 21 is fixedly connected to the fixed joint 4 by threads. Figure 2The nozzle 5 is slender, and a limiting ring 51 is provided at one end of the nozzle 5. During installation, the nozzle 5 is passed through the fixed joint 4, so that the limiting ring 51 is clamped in the fixed joint 4, and then the fixed joint 4 is threadedly connected to the air outlet pipe 21. By continuously rotating the fixed joint 4, the limiting ring 51 can be pressed and fixed at the outlet of the air outlet pipe 21, thereby fixing the nozzle 5.

[0025] Furthermore, in order to ensure the air tightness of the connection between the nozzle 5 and the air outlet pipe 21, a sealing ring 3 is provided between the contact surface of the air outlet pipe 21 and the limiting ring 51. When the fixed joint 4 squeezes the limiting ring 51, the sealing ring 3 will be deformed, thereby sealing the connection and ensuring the strength of the high-pressure airflow when it is ejected, thereby ensuring the effect of the blowing and cleaning.

[0026] When in use, multiple nozzles 5 of different lengths or diameters can be prepared, and the corresponding nozzles 5 can be replaced according to the size of the drum to be cleaned, so as to ensure the effect of spray cleaning. When replacing, the fixed joint 4 is rotated to remove the nozzle 5 corresponding to the drum size, and then the nozzle 5 is fixed by rotating the fixed joint 4, so as to achieve quick disassembly and assembly, which is convenient and practical.

[0027] A connector 6 is threadedly connected to the bottom of the air duct 1. The connector 6 has a conical structure at its joint. When in use, the conical structure can be inserted and fixed in an external air supply hose. The air supply hose is connected to an external air supply device. To improve the stability of the connection, a binding belt can be used to further fix the connection. Furthermore, the connector can also be threadedly connected to a compressed air gun head or other quick-connect connection methods.

[0028] Since the air duct 1 is relatively slender, it is inconvenient for workers to hold it during use. Figure 3 A gripping assembly 7 is installed on the air duct 1, so that it is convenient for workers to hold it for cleaning operations. The gripping assembly 7 includes a U-shaped buckle 71, a bolt 72, a nut 73, and a handle 74. During installation, the U-shaped buckle 71 is first clamped on the outer wall of the air duct 1, and the bolt 72 is passed through the two ends of the U-shaped buckle 71, and then the nut 73 is connected by threading. By tightening the nut 73, the U-shaped buckle 71 can be squeezed, so that the U-shaped buckle 71 tightens the air duct 1 to achieve fixation. The U-shaped buckle 71 is also fixedly connected with a handle 74. During use, the worker can hold the handle 74 to control the position of the nozzle 5 and spray and clean the suction hole of the drum wheel. After use, the U-shaped buckle 71 can be disassembled for convenient storage.

[0029] Specific working process:

[0030] Select a nozzle 5 of appropriate length or diameter according to the size of the drum, clip the nozzle 5 into the fixed joint 4, then connect the fixed joint 4 to the air outlet pipe 21 through threads, connect the connector 6 to the external air supply equipment through the air supply hose, start the air supply equipment, and high-pressure airflow will be ejected from the nozzle 5. Control the nozzle 5 to extend into the air suction hole of the drum for blowing and cleaning.
