[0002] When filling liquid chemicals, toxic and harmful gases are easily released, greatly polluting indoor air and affecting the health of operators. Therefore, existing technologies have proposed solutions, such as Chinese Patent Publication No. CN202574728U, which discloses a liquid filling machine with a venting function. This machine includes an electrical control box, a conveyor belt, a filling system, and a frame. Its key feature is that an exhaust hood is installed above the frame, with an exhaust pipe connected to the hood. A fan is mounted on the exhaust pipe, and a valve is located below the fan. The venting device designed in this invention, located above the filling machine, can effectively expel the gases emitted from inside the machine.

[0003] The above application still has shortcomings. The exhaust hood in the above application is too far away from the opening of the filling barrel, which does not fully extract harmful gases and poses a risk of harmful gases escaping. In addition, the filling operation is not convenient and labor-saving, which affects the overall filling operation efficiency.

[0004] Therefore, it is necessary to provide a cantilevered filling ventilation device to solve the above-mentioned technical problems. Utility Model Content

[0007] As a further embodiment of this utility model, a telescopic sleeve is installed at the end of the second cantilever support away from the first cantilever support, and the output end of the filling hose is fixed to the extension end of the telescopic sleeve. The output end of the filling hose can be adjusted up and down by means of the telescopic sleeve.

[0008] As a further embodiment of this utility model, the degassing device includes an exhaust fan body, an end connector hinged to the end of the exhaust fan body, and an air suction chamber formed inside the exhaust fan body and the end connector. The air suction chambers inside the exhaust fan body and the end connector are connected and form an integral air suction chamber. The opening of the integral air suction chamber faces downward. The input end of the air suction hose is fixed to the exhaust fan body and is connected to the air suction chamber. The integral body formed by the exhaust fan body and the end connector is provided with an insertion hole that can accommodate a filling hose that extends through it.

[0009] As a further embodiment of this utility model, a connecting plate is fixed at the opening and closing end of the end connector, a slot is provided at the end of the connecting plate, and a protruding rib that fits into the slot is fixed on the outer side wall of the exhaust fan body.

[0010] As a further embodiment of this utility model, the positions of the overall suction chamber near the filling hose and near the suction hose are respectively set as the front and rear, and the overall suction chamber is set to be wider at the front and narrower at the rear.

[0011] As a further embodiment of this utility model, a pull rod is fixed on the outer side wall of the exhaust fan body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is a set of equipment that integrates filling and ventilation functions. Through the rotatable and adjustable cantilever support, the first cantilever support and the second cantilever support, and the telescopic sleeve that can be raised and lowered, the filling hose can be moved and adjusted freely in multiple directions. This allows the filling hose to be moved freely in the working area to be aligned with the mouth of the material bucket for filling liquid materials.

This avoids the need for manual assistance in lifting the filling hose in traditional filling operations, reduces the physical exertion of operators, and effectively improves the overall filling efficiency. 2. During the filling process of the filling tube, a degassing device is used to extract and remove the small amount of polluting gas that escapes. This ensures that the polluting gas is extracted and removed in a timely manner during filling, effectively inhibiting the unorganized diffusion of toxic and harmful gases from the material and preventing the inhalation of these gases by the operators, thus improving the protection of the operators.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] Please see Figure 1-6This utility model provides a cantilevered filling and exhaust device, including a bracket 9, a connector rod 1 fixed on the bracket 9, a rotating seat 6 fixed on the side of the connector rod 1, a first cantilever bracket 7 hinged inside the rotating seat 6, a second cantilever bracket 10 hinged to the end of the first cantilever bracket 7 away from the rotating seat 6, a filling hose 2 and an air suction hose 3 arranged along the length direction of the first cantilever bracket 7 and the second cantilever bracket 10 are jointly fixed on the first cantilever bracket 7 and the second cantilever bracket 10, and an output end of the filling hose 2 is provided with The device includes a degassing device 4, through which the filling hose 2 passes. The input end of the suction hose 3 is connected to the inside of the degassing device 4. A telescopic sleeve 8 is installed at the end of the second cantilever bracket 10 away from the first cantilever bracket 7. The output end of the filling hose 2 is fixed to the extension end of the telescopic sleeve 8. The output end of the filling hose 2 can be adjusted up and down via the telescopic sleeve 8. A certain length of adjustable allowance is left in the parts of the filling hose 2 and the suction hose 3 near the degassing device 4. This utility model is a set that integrates filling and ventilation. This integrated device connects the filling hose 2 and the exhaust / suction hose 3 to an external material pump and an air pump, respectively. Through a rotatable and adjustable cantilever bracket (first cantilever bracket 7 and second cantilever bracket 10) and a height-adjustable telescopic sleeve 8, the filling hose 2 can move freely in multiple directions. This allows the filling hose 2 to easily move freely within the working area, aligning with the opening of the material container 5 for filling with liquid materials. Multiple empty material containers 5 can be easily filled by continuously pushing them manually, providing flexible operating space and avoiding the need for manual assistance in lifting the filling hose in traditional filling operations. This reduces the physical exertion of operators and effectively improves overall filling efficiency. Simultaneously, during the filling process, a degassing device 4 removes any small amount of escaping pollutants, ensuring timely removal of these gases and effectively suppressing the unorganized diffusion of toxic and harmful gases from the material. This prevents operators from inhaling these gases and improves their safety.

[0017] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the degassing device 4 includes an exhaust fan body 401, with an end connector 402 hinged to the end of the exhaust fan body 401. An air intake chamber 407 is formed inside the exhaust fan body 401 and the end connector 402. The air intake chambers 407 in the exhaust fan body 401 and the end connector 402 are connected and form an integral air intake chamber 409. The integral air intake chamber 409 has its opening facing downwards. The input end of the suction hose 3 is fixed to the exhaust fan body 401 and is connected to the air intake chamber 407. The integral structure consisting of the exhaust fan body 401 and the end connector 402 is provided with a passageway that can accommodate the filling hose 2. The protruding insertion hole 403; during the filling process of the filling hose 2, the suction hose 3 and the overall suction chamber 409 are used to draw in negative pressure, thereby removing the small amount of polluting gas escaping from the opening of the material tank 5 during the filling process through the downward-facing overall suction chamber 409. By controlling the suction force in the overall suction chamber 409 within a small range, due to the significant difference in weight between liquid and gas, the escaping polluting gas is promptly drawn out during filling without causing accidental drawing of liquid, effectively inhibiting the unorganized diffusion of toxic and harmful gases from the material, preventing the unorganized diffusion of toxic and harmful gases from being inhaled by operators, and improving the protection of operators.

[0018] Further as Figure 4 , Figure 5 and Figure 6 As shown, it is worth noting that a connecting plate 404 is fixed at the opening and closing end of the end connector 402. The end of the connecting plate 404 is provided with a slot 405. A rib 406 that fits into the slot 405 is fixed on the outer side wall of the exhaust fan body 401. When the exhaust fan body 401 is closed, the rib 406 is inserted into the slot 405 of the connecting plate 404, thereby locking the exhaust fan body 401 and the end connector 402 through the connecting plate 404, so that the exhaust fan body 401 and the end connector 402 are fixedly connected as one unit. Conversely, by rotating the end connector 402 to open it, the filling hose 2 can be easily removed, facilitating the replacement and maintenance of the filling hose 2.

[0019] Further as Figure 4 and Figure 5 As shown, it is worth noting that the overall suction chamber 409 is positioned at the front and rear of the filling hose 2 and the suction hose 3, respectively, and the overall suction chamber is wider at the front and narrower at the back. The overall suction chamber 409 is designed to surround the insertion hole 403, and the overall suction chamber 409 forms a shape that is wider at the front and narrower at the back, so that the suction force is more uniform near the opening of the material bucket 5, controlling the internal static pressure distribution and achieving uniform suction.

[0020] Further as Figure 5 As shown, it is worth noting that a pull rod 408 is fixed on the outer wall of the exhaust fan body 401.

[0021] In summary, this utility model is a device that integrates filling and ventilation functions, allowing the filling hose 2 to move freely within the working area and be aligned with the opening of the material container 5 for filling liquid materials. It provides flexible operating space, avoids the need for manual assistance in lifting the filling hose in traditional filling operations, reduces the physical exertion of operators, and effectively improves overall filling efficiency. At the same time, during the filling process of the filling hose 2, the degassing device 4 extracts and removes the small amount of polluting gas that escapes, thus forming a timely extraction and removal of polluting gas during filling, effectively inhibiting the unorganized diffusion of toxic and harmful gases from the material, preventing the inhalation of toxic and harmful gases by operators, and improving the protection of operators.

[0022] The feed pump and the exhaust pump can be purchased from the market. The feed pump and the exhaust pump are equipped with a power supply. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be repeated in the specification.
