Description

Technical Field

[0001] This utility model relates to the field of hot air curtain technology, specifically a combined hot air curtain. Background Technology

[0002] A hot air curtain is an air conditioning device mainly used at the entrances and exits of buildings. It forms an air barrier by blowing out hot air to prevent the convection and exchange of indoor and outdoor air, thereby achieving many functions such as energy saving, heat preservation, dust prevention, and insect prevention.

[0003] Existing hot air curtains are generally of fixed length. When the hot air curtain is working, the fan usually draws outside air into the hot air curtain, and then the gas flows through the electric heating wire under the action of the guide plate, and finally blows out from the air outlet to form an air barrier.

[0004] Existing hot air curtains have the following problems: hot air curtains are generally of fixed length, while the size of building entrances and exits is not fixed, so the hot air curtains cannot be installed according to actual needs, which leads to unsatisfactory installation results and low practicality. Therefore, we propose a combined hot air curtain. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a modular hot air curtain. By combining hot air curtains of fixed length through a combination mechanism, hot air curtains of appropriate length can be combined according to the size of the building's entrance and exit. The installation effect is good, the practicality of the hot air curtain is improved, and the problems in the background technology can be effectively solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined hot air curtain, comprising an air curtain housing and a combination mechanism;

[0007] The assembly mechanism includes a fixed base, slide rails, insert blocks, a rotating disk, sliding protrusions, annular grooves, limiting grooves, limiting posts, and limiting plates. The left side of the air curtain housing is equipped with a fixed base, and the left side of the fixed base has evenly distributed slide rails. Insert blocks are slidably connected inside each slide rail. The left side of the fixed base is rotatably connected to a rotating disk, and the left side of the fixed base has an annular groove. The right side of the rotating disk has evenly distributed sliding protrusions, all slidably connected inside the annular grooves. The left side of the rotating disk has evenly distributed limiting grooves, and limiting posts are slidably connected inside each limiting groove. The right side of each limiting post is fixedly connected to the left side of an adjacent insert block, and the left side of each limiting post has a limiting plate. By assembling the air curtains of fixed lengths together using this assembly mechanism, air curtains of appropriate length can be assembled according to the size of the building's entrances and exits, resulting in good installation and improved practicality.

[0008] Furthermore, it also includes a microcontroller, which is located outside the air curtain machine housing. The input terminal of the microcontroller is electrically connected to an external power supply to facilitate the normal operation of the equipment.

[0009] Furthermore, the assembly mechanism also includes a fixed column and a cross slot. The fixed column is located on the right side of the air curtain housing. The central axis of the fixed column coincides with that of the fixed base. A cross slot is provided inside the fixed column to facilitate the assembly of the hot air curtain.

[0010] Furthermore, the combined mechanism also includes a lever, which is fixedly connected to the outer surface of the rotating disk to facilitate the normal operation of the combined mechanism.

[0011] Furthermore, the air curtain housing has an internal isolation plate, and the upper surface of the isolation plate has evenly distributed mounting holes. Each mounting hole is equipped with a fan. The air curtain housing also has a first guide plate, which is curved and located below the fan. The upper surface of the air curtain housing has evenly distributed air inlets. The input end of the fan is electrically connected to the output end of the microcontroller to facilitate the formation of an air barrier.

[0012] Furthermore, the air curtain housing is equipped with a filter screen inside, which is located between the top of the fan and the top wall of the air curtain housing to prevent dust from entering and affecting the effect of blowing out the air curtain.

[0013] Furthermore, the air outlet of the air curtain housing is provided with guide plates on both the upper and lower sides, and an electric heating wire is provided at the air outlet of the air curtain housing. The electric heating wire is distributed in an S-shape and is located on the rear side of the guide plate. The input end of the electric heating wire is electrically connected to the output end of the microcontroller to facilitate heating of the airflow.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This combined hot air curtain has the following advantages:

[0015] Insert the fixing post of one modular air curtain into the fixing base of another modular air curtain, and then turn the lever clockwise. The lever drives the rotating disk to rotate. Because the limiting groove is arc-shaped and the center of the arc is not the center of the rotating disk, the rotation of the rotating disk causes the limiting post to both slide and rotate relative to the rotating disk. The limiting post drives the insert to move along the track of the slide rail towards the center of the fixing base until the insert is inserted into the adjacent socket on the cross slot. By assembling the two modular air curtains together, the appropriate length of air curtain can be combined according to the size of the building's entrance and exit. The installation effect is good, which improves the practicality of the air curtain. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-6This embodiment provides a technical solution: a combined hot air curtain, comprising an air curtain housing 1 and a combined mechanism 3, and further including a microcontroller 2. The microcontroller 2 is disposed outside the air curtain housing 1, and its input terminal is electrically connected to an external power supply. An isolation plate 4 is provided inside the air curtain housing 1, and evenly distributed mounting holes are formed on the upper surface of the isolation plate 4. A fan 5 is installed inside each mounting hole. A guide plate 6, which is curved, is provided inside the air curtain housing 1 and is located below the fan 5. Evenly distributed air inlets 9 are formed on the upper surface of the air curtain housing 1, and the input terminal of the fan 5 is electrically connected to the output terminal of the microcontroller 2. A filter 10 is provided inside the air curtain housing 1, located above the fan 5 and between the filter 1 and the top wall of the air curtain housing 1. The air curtain housing 1 has guide plates 8 on both the upper and lower sides of the air outlet. An electric heating wire 7 is installed at the air outlet of the air curtain housing 1. The electric heating wire 7 is distributed in an S-shape and is located on the rear side of the guide plate 8. The input end of the electric heating wire 7 is electrically connected to the output end of the microcontroller 2. Then, with the air outlet facing the ground, the assembled combined hot air curtain is installed in the required position. Then, the microcontroller 2 is operated to turn on the fan 5. The fan 5 draws outside air into the interior of the air curtain housing 1 through the air inlet 9. The airflow passes through the filter screen 10 to filter out dust. Then, the electric heating wire 7 is turned on. The airflow passes through the electric heating wire 7 under the action of the guide plate 6. The temperature of the airflow rises and is blown out under the action of the guide plate 8 to form an air barrier to prevent the convection exchange of indoor and outdoor air.

[0025] Combination mechanism 3 includes a fixed base 301, slide rails 302, insert blocks 303, rotating disk 304, sliding protrusions 305, annular grooves 306, limiting grooves 307, limiting posts 308, and limiting plates 309. The fixed base 301 is located on the left side of the air curtain housing 1. Slide rails 302 are evenly distributed on the left side of the fixed base 301. Insert blocks 303 are slidably connected inside each slide rail 302. The rotating disk 304 is rotatably connected to the left side of the fixed base 301. An annular groove 306 is formed on the left side of the fixed base 301. Sliding protrusions 305, annular grooves 306, and evenly distributed... The sliding protrusions 305 are all slidably connected to the inside of the annular groove 306. The left side of the rotating disk 304 has evenly distributed limiting grooves 307, and each limiting groove 307 has a limiting post 308 slidably connected inside. The right side of each limiting post 308 is fixedly connected to the left side of the adjacent insert block 303. A limiting piece 309 is provided on the left side of each limiting post 308. The combined mechanism 3 also includes a fixing post 310 and a cross slot 311. The right side of the air curtain housing 1 has a fixing post 310, which coincides with the central axis of the fixing base 301. The column 310 has a cross-shaped slot 311 inside. The combination mechanism 3 also includes a lever 312. The lever 312 is fixedly connected to the outer surface of the rotating disk 304. The operator installs the combined hot air curtain in the required position. If multiple combined hot air curtains need to be used together, align the right side of one air curtain housing 1 with the left side of another air curtain housing 1 (at this time, the fixing base 301 of one combined hot air curtain coincides with the central axis of the fixing column 310 of another combined hot air curtain). Then, bring the two air curtain housings 1 closer together until the fixing column 310 passes through the rotating disk 304. 4. Insert the fixed base 301 into the interior, and then rotate the lever 312 clockwise. The lever 312 drives the rotating disk 304 to rotate. Since the limiting groove 307 is arc-shaped and the center of the arc is not the center of the rotating disk 304, the rotation of the rotating disk 304 causes the limiting post 308 to slide and rotate relative to the rotating disk 304. Under the restriction of the slide rail 302, the limiting post 308 drives the insert block 303 to move along the trajectory of the slide rail 302 towards the center of the fixed base 301 until the insert block 303 is inserted into the interior of the adjacent socket on the cross slot 311, assembling the two combined hot air curtains together.

[0026] The working principle of the combined hot air curtain provided by this utility model is as follows: The operator installs the combined hot air curtain in the required position. If multiple combined hot air curtains are needed for combined use, the right side of one air curtain housing 1 is aligned with the left side of another air curtain housing 1 (at this time, the central axis of the fixing base 301 of one combined hot air curtain coincides with the central axis of the fixing column 310 of another combined hot air curtain). Then, the two air curtain housings 1 are brought closer together until the fixing column 310 passes through the rotating disk 304 and inserts into the fixing base 301. Then, the lever 312 is rotated clockwise, causing the rotating disk 304 to rotate. Because the limiting groove 307 is arc-shaped and the center of the arc is not the center of the rotating disk 304, the rotation of the rotating disk 304 causes the limiting column 308 to rotate relative to the rotating disk 304. The moving plate 304 both slides and rotates. Under the restriction of the slide rail 302, the limiting post 308 drives the insertion block 303 to move along the track of the slide rail 302 towards the center of the fixed seat 301 until the insertion block 303 is inserted into the interior of the adjacent socket on the cross slot 311, assembling the two combined hot air curtains together. Then, with the air outlet facing the ground, the combined hot air curtain is installed in the required position. Then, the microcontroller 2 is controlled to turn on the fan 5. The fan 5 draws outside air into the interior of the air curtain housing 1 through the air inlet 9. The airflow passes through the filter screen 10 to filter out dust. Then, the electric heating wire 7 is turned on. The airflow passes through the electric heating wire 7 under the action of the first guide plate 6. The temperature of the airflow rises and is blown out under the action of the second guide plate 8 to form an air barrier to prevent the convection exchange of indoor and outdoor air.

[0027] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be a PI C10F200, the fan 5 can be an SF axial flow fan, and the microcontroller 2 controls the operation of the fan 5 and the electric heating wire 7 using methods commonly used in the prior art.
