Description
Technical Field
[0001] The utility model relates to the technical field of exhaust equipment, and more specifically, to a heat-insulating exhaust device. Background Art
[0002] Exhaust equipment is undoubtedly an indispensable part of modern architecture, construction and daily life. It plays a vital role in maintaining environmental air quality, removing harmful gases and maintaining air circulation. In more occasions that require efficient and controllable ventilation, mechanical exhaust has shown its unique advantages. Mechanical exhaust relies on the wind pressure and air volume provided by the fan. Through a complex pipeline system and air supply and exhaust vents, fresh air or treated air from the outside is accurately delivered to any workplace in the building. This method not only has high ventilation efficiency, but also can be precisely controlled as needed to ensure the stability of indoor air quality. However, during the installation process of traditional mechanical exhaust equipment, it is usually necessary to first drill holes in the wall or ceiling, then embed the exhaust device into these holes, and finally fix it with fixing devices such as bolts. Although this installation method is simple and direct, there are some problems in the long-term use process. Due to the complexity and changeability of the external environment, fixings such as bolts are easily affected by factors such as vibration and corrosion, resulting in loosening or falling off of the fixings. Once the fixings fail, the exhaust device will lose its fixation, which will not only affect the ventilation effect, but also may threaten the structural safety of the building. Therefore, it needs to be improved and optimized. Utility Model Content

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figures 1 to 5 As shown, the utility model provides a heat-insulating exhaust device, including a rectangular block 1, four rectangular grooves 2 are provided on the back of the rectangular block 1, and fixing mechanisms are respectively arranged inside the four rectangular grooves 2. The fixing mechanisms include a movable block 3 slidably mounted on the inner wall of the rectangular groove 2, a tooth groove 4 is provided at the bottom of the movable block 3, a rotating rod 6 is threadedly mounted on the inner wall of the front side of the rectangular groove 2, a tooth column 5 is fixedly sleeved on the outer wall of the rotating rod 6, the tooth column 5 is meshed with the tooth groove 4, and a horizontal plate 7 is fixedly mounted on the back of the rotating rod 6.
[0021] By rotating the horizontal plate 7, the horizontal plate 7 drives the rotating rod 6 to rotate, and the tooth column 5 interacts with the tooth groove 4 at the bottom of the movable block 3, so that the movable block can slide in the rectangular groove 2, so that the user can flexibly adjust the position of the movable block 3 according to specific needs, so that the movable block 3 can contact with the installation groove and strengthen the fixation: and because the tooth column 5 is tightly engaged with the tooth groove 4, the movable block 3 will remain in a fixed position and is not easy to loosen or shift, thereby ensuring the stability and safety of the fixed object. Then, through the four rectangular grooves 2 provided on the back of the rectangular block 1, and each groove is provided with a fixing mechanism, it can be fixed at different positions at the same time. Compared with the traditional device, it not only improves the wide applicability of the device in various scenarios, but also improves the safety of the device in daily use.
[0022] The user first places the rectangular block 1 in the opened slot, and then rotates the horizontal plate 7, which drives the rotating rod 6 to rotate. The tooth column 5 interacts with the tooth groove 4 at the bottom of the movable block 3, so that the movable block can slide in the rectangular groove 2, so that the movable block 3 can be in tight contact with the inner wall of the installation groove to strengthen the fixation.
[0023] Among them, the front side of the rectangular block 1 is rotatably installed with a rotating rod 13, a rotating rod 2 14, a rotating rod 3 17, a rotating rod 4 18, and a rotating rod 5 19. The rotating rod 13, the rotating rod 2 14, the rotating rod 3 17, the rotating rod 4 18, and the rotating rod 5 19 all pass through the rectangular block 1. The rotating rod 2 14, the rotating rod 3 17, the rotating rod 4 18, and the rotating rod 5 19 are all connected by a belt 15. Four fan blades 16 are fixedly installed on the outer walls of the rotating rod 13, the rotating rod 2 14, the rotating rod 3 17, the rotating rod 4 18, and the rotating rod 5 19, and the fan blades 16 are distributed in a circular array.
[0024] By setting up multiple sets of rotating rods, all the fan blades can be moved synchronously by rotating one of the rotating rods, without having to operate each fan blade individually. This not only simplifies the operation process, but also improves the convenience of use. Moreover, since the rotating rods are connected by a belt 15 for transmission, the stability and synchronization of the rotation can be ensured. At the same time, the circular array distribution of the multiple fan blades 16 also makes the wind force more uniform and stable. Compared with traditional devices, a more efficient, stable and uniform exhaust effect is achieved.
[0025] After the device is installed, the user can start the motor 12, and the output shaft of the start motor 12 drives the rotating rod 13 to rotate, and drives the rotating rod 2 14, the rotating rod 3 17, the rotating rod 4 18, the rotating rod 5 19 and the fan blades 16 to rotate synchronously through the belt 15 transmission connection, thereby ensuring the continuity and stability of the wind output.
[0026] The top and bottom of the transverse plate 7 are respectively provided with rubber strips 8 , and the rubber strips 8 are symmetrically distributed.
[0027] The rubber strip 8 provides additional friction, so that the user can get a more stable and reliable grip when rotating the horizontal board 7. This friction helps prevent the horizontal board 7 from slipping or accidentally rotating during the rotation process, thereby increasing the safety and stability of the operation.
[0028] The movable block 3 is designed to be L-shaped on the outside, and the bottom of the L-shape extends to the outside of the rectangular block 1.
[0029] Through the L-shaped design, the movable block 3 has a larger supporting area in the rectangular block 1, thereby increasing the overall stability. Even under the action of external force, the movable block 3 is not easy to shake or shift, ensuring the accuracy and reliability of its position.
[0030] Among them, an air outlet hood 10 is fixedly installed on the back of the rectangular block 1, a heat insulation box 11 is fixedly installed on the front of the air outlet hood 10, a motor 12 is fixedly installed on the front of the heat insulation box 11, and the output shaft of the motor 12 is fixedly connected to the bottom of the rotating rod 13.
[0031] By starting the motor 12, its output shaft drives the rotating rod 13 to rotate, and then drives the rotating rod 2 14, the rotating rod 3 17, the rotating rod 4 18, the rotating rod 5 19 and the fan blade 16 to rotate synchronously through the belt 15 transmission connection, ensuring the continuity and stability of the wind output.
[0032] An air inlet cover 9 is fixedly mounted on the front of the rectangular block 1 , and the diameter of the air inlet cover 9 is the same as the diameter of the air outlet cover 10 .
[0033] By making the diameters of the air inlet hood 9 and the air outlet hood 10 the same, they can ensure that the air volume of the air inlet and the air outlet is balanced during ventilation. This balance not only helps to maintain the stability of the air flow inside the device, but also avoids air flow turbulence or noise caused by mismatched air volume.
[0034] The working principle and use process of this utility model:
[0035] The user first places the rectangular block 1 in the opened slot, and then rotates the horizontal plate 7, which drives the rotating rod 6 to rotate. The tooth column 5 interacts with the tooth groove 4 at the bottom of the movable block 3, so that the movable block can slide in the rectangular groove 2, so that the movable block 3 can be in tight contact with the inner wall of the installation groove to strengthen the fixation.
[0036] After the device is installed, the user can start the motor 12, and the output shaft of the start motor 12 drives the rotating rod 13 to rotate, and drives the rotating rod 2 14, the rotating rod 3 17, the rotating rod 4 18, the rotating rod 5 19 and the fan blades 16 to rotate synchronously through the belt 15 transmission connection, thereby ensuring the continuity and stability of the wind output.
