Description

Technical Field

[0001] This utility model belongs to the field of heater technology, specifically an air conditioning metal tubular heater with integrated overheat protection. Background Technology

[0002] The commercial air conditioning metal tubular heater with integrated overheat protection is an electric heating device that combines metal tubular heating technology with an overheat protection mechanism. It is specifically designed for commercial air conditioning systems to improve heating efficiency and ensure safe operation. It uses a metal tubing made of stainless steel, copper, or titanium alloy as the outer shell, with a high-resistance alloy heating wire (such as nickel-chromium alloy) embedded inside to generate heat through electric current. It has a built-in temperature sensor (such as a thermocouple or thermistor) and fuse to monitor the heater surface temperature in real time. When the temperature sensor detects that the surface temperature exceeds a set threshold, it triggers a temperature control switch to cut off the power supply, thus achieving overheat protection.

[0003] Existing integrated overheat protection air conditioner heaters take a long time to start up and heat up, and cannot quickly heat up to the required temperature, resulting in poor performance. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an air conditioner metal tubular heater with integrated overheat protection, which effectively solves the problem that the existing air conditioner heaters with integrated overheat protection take a long time to start up and heat up, cannot quickly heat up to the required temperature, and have poor performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air conditioner metal tubular heater with integrated overheat protection, comprising a device body, strip grooves on both sides of the device body, five rods inserted into each of the two strip grooves, a metal heating tube fixedly installed between one end of each of the ten rods, and pins fixedly installed at the ends of the ten rods away from the metal heating tubes. Transmission plates are provided on both sides of the device body, five transmission grooves are provided on the surface of each of the two transmission plates, and ten pins are inserted into the ten transmission grooves. Slider blocks are fixedly installed at both ends of the two transmission plates on the side closest to each other. Two sliding grooves are respectively provided on the lower part of both sides of the device body, and four sliders are slidably installed inside the four sliding grooves. A drive motor is fixedly installed on the lower part of the middle of one side of the device body via a support plate. Two support arms are fixedly installed between the two ends of the two transmission plates. A transmission assembly is provided at the output end of the drive motor, and the transmission assembly is connected to the two support arms. When the drive motor operates, it outputs power to the two support arms through the transmission assembly.

[0006] Preferably, the transmission assembly includes a first rotating rod, which is fixedly installed at the output end of the drive motor. A worm gear is fixedly installed at one end of the first rotating rod, and a second rotating rod is fixedly installed at one end of the worm gear. One end of the second rotating rod is rotatably connected to the bottom of the device body through a bearing seat. A worm wheel is meshed with the lower part of the worm gear surface, and a shaft is fixedly installed in the middle of the worm wheel. Two bushings are rotatably installed on the surface of the shaft, and the upper parts of the two bushings are fixedly connected to the inner walls of both ends of the device body through connecting rods.

[0007] Preferably, both ends of the shaft are fixedly mounted with driving bevel gears, the upper parts of the surfaces of the two driving bevel gears are meshed with driven bevel gears, the tops of the two driven bevel gears are fixedly mounted with rotating shafts, the surfaces of the two rotating shafts are rotatably mounted with bearings, and the surfaces of the two bearings are fixedly connected to the bottom of the device body through fixing rods.

[0008] Preferably, each of the rotating shafts has a threaded rod fixedly installed on its top. The top of each of the two threaded rods is rotatably connected to both ends of the device body through a positioning seat. The surfaces of the two threaded rods are threaded with threaded sleeves, and the sides of the two threaded sleeves that are close to each other are fixedly connected to the two support arms.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When starting, the operator starts the drive motor to drive the first rotating rod to rotate. When the first rotating rod rotates, it drives the worm wheel to rotate through the worm. When the worm rotates, it drives the second rotating rod to rotate along the shaft seat, which improves the stability of the worm rotation. When the worm wheel rotates, it drives the shaft to rotate inside the two bushings. When the shaft rotates, it drives the two driven bevel gears to rotate through the two active bevel gears.

[0010] When the two driven bevel gears rotate, they drive the two shafts to rotate inside the two bearings. When the two shafts rotate, they drive the two threaded rods to rotate along the two positioning seats. When the threaded rods rotate, they drive the two support arms to move downward through the two threaded sleeves. When the two support arms move downward, they drive the two transmission plates to move downward. When the transmission plates move downward, they drive the sliders to slide along the slide grooves, which increases the stability of the two transmission plates when they move. When the two transmission plates move downward, they drive the pins to move inward synchronously through the cooperation of the transmission grooves. When the pins move, they drive the insert rods to slide along the inside of the strip grooves. When the insert rods move inward, they drive the multiple metal heating tubes to move closer to each other, so that the multiple metal heating tubes gather heat and affect each other, thereby increasing the heating rate of the metal heating tubes. This allows the integrated overheat protection air conditioning heater to effectively reduce the time consumed in starting up and heating, and can quickly heat up to the required temperature.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1 to 5The present invention includes a device body 1. Both sides of the device body 1 have strip-shaped grooves 2. Five rods 3 are inserted into each of the two strip-shaped grooves 2. A metal heating tube 4 is fixedly installed between one end of each of the ten rods 3. A pin 5 is fixedly installed at the end of each of the ten rods 3 away from the metal heating tube 4. Both sides of the device body 1 have transmission plates 6. Each surface of the two transmission plates 6 has five transmission grooves 7. Ten pins 5 are inserted into the ten transmission grooves 7. Slider 8 is fixedly installed at both ends of the two transmission plates 6 on the side closest to each other. Two sliding grooves 9 are respectively opened on the lower part of both sides of the device body 1. Four sliders 8 are slidably installed inside the four sliding grooves 9. A drive motor 12 is fixedly installed on the lower part of the middle of one side of the device body 1 via a support plate 11. Two support arms 10 are fixedly installed between the two ends of the two transmission plates 6. A transmission assembly is provided at the output end of the drive motor 12. The transmission assembly is connected to the two support arms 10. When the drive motor 12 is running, it outputs power to the two support arms 10 through the transmission assembly.

[0021] During startup, the operator starts the drive motor 12, which drives the transmission assembly to operate. The operation of the transmission assembly causes the two support arms 10 to move downwards, which in turn causes the two transmission plates 6 to move downwards. As the transmission plates 6 move downwards, they both cause the sliders 8 to slide along the slide grooves 9, increasing the stability of the two transmission plates 6 during movement. As the two transmission plates 6 move downwards, they both cause the pins 5 to move inwards synchronously through the cooperation of the transmission grooves 7. As the pins 5 move, they both cause the rods 3 to slide along the inside of the strip grooves 2. When the rods 3 move inwards, they cause multiple metal heating tubes 4 to move closer together, causing the multiple metal heating tubes 4 to accumulate heat and influence each other, thereby increasing the heating rate of the metal heating tubes 4. This allows the integrated overheat protection air conditioning heater to effectively reduce the time required for startup and heating, and to quickly heat to the required temperature.

[0022] The transmission assembly includes a first rotating rod 13, which is fixedly installed at the output end of the drive motor 12.

A shaft 18 is fixedly installed in the middle of the worm wheel 17. Two bushings 19 are rotatably installed on the surface of the shaft 18. The upper parts of the two bushings 19 are fixedly connected to the inner walls of both ends of the device body 1 through connecting rods 20.

[0023] The operator starts the drive motor 12 to drive the first rotating rod 13 to rotate. When the first rotating rod 13 rotates, it drives the worm wheel 17 to rotate through the worm 14. When the worm 14 rotates, it drives the second rotating rod 15 to rotate along the bearing 16, which improves the stability of the worm 14 when it rotates. When the worm wheel 17 rotates, it drives the shaft 18 to rotate inside the two bushings 19.

[0024] Both ends of the shaft 18 are fixedly mounted with driving bevel gears 21. The upper part of the surface of the two driving bevel gears 21 is meshed with driven bevel gears 22. The top of the two driven bevel gears 22 is fixedly mounted with rotating shafts 23. The surface of the two rotating shafts 23 is rotatably mounted with bearings 24. The surface of the two bearings 24 is fixedly connected to the bottom of the device body 1 through a fixing rod 25.

[0025] When shaft 18 rotates, it drives two driven bevel gears 22 to rotate through two driving bevel gears 21.

[0026] The top of each rotating shaft 23 is fixedly installed with a threaded rod 26. The top of each threaded rod 26 is rotatably connected to both ends of the main body 1 of the device through a positioning seat 27. The surfaces of each threaded rod 26 are threadedly connected with threaded sleeves 28. The side of each threaded sleeve 28 that is close to each other is fixedly connected to two support arms 10.

[0027] When the two rotating shafts 23 rotate, they drive the two threaded rods 26 to rotate along the two positioning seats 27. When the threaded rods 26 rotate, they drive the two support arms 10 to move downward through the two threaded sleeves 28.
