[0002] In the construction of urban and rural sewage treatment and sanitation facilities, a large amount of harmful and odor gas is generated in the process of treating organic waste in the septic tank. In order to protect the health and safety of the surrounding environment and personnel, an effective exhaust system is very important. With the increasing strictness of environmental protection requirements and the continuous improvement of people's expectations for the quality of living environment, the existing septic tank exhaust duct air guiding device has been difficult to meet the demand in performance, reliability, energy saving and other aspects. Therefore, it is an urgent need to develop a high-efficiency, durable, energy-saving and well-sealed jet flow air guiding device to solve the problem of septic tank exhaust.

[0003] In the past septic tank exhaust duct system, it is generally a simple fan exhaust system, which lacks effective air inlet adjustment mechanism and cannot realize two-end air guiding work. It can only perform single-direction exhaust or air inlet and cannot flexibly change direction according to actual demand. This leads to the problem that it cannot effectively accelerate the exhaust of gas in the septic tank, making harmful gas easy to accumulate and increasing the risk of safety hazards and environmental pollution. Moreover, when it is necessary to introduce external pure air to promote gas exchange, the traditional device cannot achieve this, leading to uneven gas exchange in the septic tank and the existence of local high or low gas concentration, which affects the normal function and treatment effect of the septic tank. Due to the lack of multifunctional and flexible design, the traditional air guiding device is not capable of dealing with the complex gas treatment requirements of the septic tank and cannot effectively ensure the safe operation of the septic tank and the quality of the surrounding environment. Therefore, a jet flow air guiding device is proposed to solve the above problems. SUMMARY

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 2 An embodiment of this utility model is provided: a jet-induced airflow device, including a housing 1. The housing 1 has a trapezoidal design and a rectangular hole on its left side. The top of the housing 1 is connected to a mounting box 2, which serves to install and fix the device. A motor 3 is provided on the left side of the mounting box 2. The motor 3 is a power source for rotating the device. An exhaust mechanism 4 is provided inside the mounting box 2. An amplification mechanism 5 is provided on the surface of the housing 1.

[0024] Reference Figure 1 - Figure 3The exhaust mechanism 4 consists of a drive assembly and an exhaust assembly. The exhaust assembly includes a worm gear 401, the surface of which is rotatably connected to the inner wall of the mounting box 2. A rotating tooth 402 is fixedly connected to the top of the outer shell 1. When the worm gear 401 rotates, it rotates in conjunction with the rotating tooth 402, causing the rotating tooth 402 to rotate as well. A high-speed fan blade 405 is rotatably connected to the inner wall of the outer shell 1. The blade of the high-speed fan blade 405 has an arc-shaped design and guides the exhaust gas from the bottom to the other end through the principle of high-speed rotation. The bottom of the high-speed fan blade 405 is connected to an air inlet plate 406, which serves as the exhaust gas inlet. The worm gear 401 is fixedly connected to the output end of the motor 3. When the motor 3 is turned on, it will drive the worm gear 401 to rotate. The worm gear 401 and the rotating tooth 402 mesh with each other. The bottom of the rotating tooth 402 is fixedly connected to the top of the outer shell 1 through a connecting rod.

[0025] Reference Figure 1 - Figure 3 The drive component includes a controller 403, which controls the high-speed fan blade 405. It has high power and provides high-speed kinetic energy. A mounting plate 404 is fixedly connected to the inner wall of the outer casing 1. The mounting plate 404 is used to install the high-speed fan blade 405. The controller 403 is fixedly connected to the right side of the outer casing 1. The controller 403 is electrically connected to the high-speed fan blade 405, thereby realizing the air intake work at both ends of the septic tank exhaust pipe. The exhaust end is turned to accelerate the discharge of the gas accumulation inside the septic tank, while the intake end is turned to introduce relatively clean air from outside into the septic tank, making the gas exchange inside the septic tank more uniform, thus having good functionality.

[0026] Reference Figure 4 The amplification mechanism 5 includes a side sliding frame 501, with an air inlet 502 slidably connected to the inner wall of the side sliding frame 501. A pull rod 505 is fixedly connected to the bottom of the air inlet 502. Pulling the pull rod 505 causes the air inlet 502 to slide and expand along the inner wall of the side sliding frame 501. The rear part of the side sliding frame 501 is fixedly connected to the front part of the outer shell 1. The upper surface of the air inlet 502 is in contact with the bottom of the outer shell 1. The amplification mechanism 5 also includes a top sliding frame 503, with its inner wall slidably connected to... The cover plate 504 is moved by the air vent 502. The right side of the top slide 503 is fixedly connected to the left side of the outer shell 1. The cover plate 504 slides down along the inner wall of the top slide 503 and finally forms a rectangular ventilation opening with the air vent 502. The front part of the cover plate 504 is slidably connected to the inner side of the air vent 502. Finally, by pulling out the air vent 502, the jet air duct is lengthened, the air pushing distance is increased, and the airflow is guided and transported more effectively, thereby enhancing the overall air-driving effect.

[0027] Working Principle: In use, this device is used for ventilation ducts in septic tanks. The operator pulls the lever 505 along the inner wall of the septic tank ventilation duct. The lever 505 causes the air diffuser 502 to slide and unfold along the inner wall of the side sliding frame 501. The air diffuser 502 moves the cover plate 504, which slides down along the inner wall of the top sliding frame 503, ultimately forming a rectangular ventilation opening with the air diffuser 502. This increases the air pushing distance, thereby more effectively guiding and transporting airflow and enhancing the overall ventilation effect. After preparation, the operator starts the control unit 403. The control unit 403 drives the high-speed fan blade 405 along the inner wall of the mounting plate 404. The machine rotates to begin the ventilating process. The extracted exhaust gas is ejected through the rectangular hole on the left side of the outer casing 1. When the operator needs to ventilate the other end of the ventilation duct, the operator starts the motor 3. The motor 3 drives the worm gear 401 to rotate, which in turn drives the rotating gear 402 to rotate. The rotating gear 402 then drives the outer casing 1 at its bottom to rotate to the other end. This allows for ventilating both ends of the septic tank exhaust pipe. Turning to the exhaust end accelerates the discharge of accumulated gas inside the septic tank, while turning to the intake end allows for the introduction of relatively clean air from outside into the septic tank, making the gas exchange inside the septic tank more uniform and providing good functionality.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
