Description

Technical Field

[0001] This application relates to the field of air conditioner exhaust sterilization, and in particular to a spiral-shaped air conditioner built-in ultraviolet sterilization pipe. Background Technology

[0002] The main types of air conditioners are: cabinet air conditioners, wall-mounted air conditioners, water-cooled air conditioners, window air conditioners (half indoor and half outdoor), central air conditioning, and dual-split air conditioners (one outdoor unit controls two indoor units simultaneously).

[0003] Currently, air conditioners on the market generally have air deflectors installed at the air outlet to guide the direction of the airflow. The airflow passes through the air deflector and comes into direct contact with it. However, the air deflectors in the current technology lack ultraviolet sterilization design.

[0004] For example, an air conditioner vent with publication number CN209147397U discloses an air conditioner vent including an air conditioner housing. An air outlet duct and an air outlet are disposed inside the housing, with the air outlet duct located on one side of the air outlet. An activated carbon filter layer, an ultraviolet germicidal lamp, and a high-efficiency filter are disposed inside the air outlet, with the ultraviolet germicidal lamp located between the activated carbon filter layer and the high-efficiency filter. An air outlet plate is disposed on one side of the air outlet, with a rotating shaft movably connected internally to the air outlet plate. An adjustable fan blade is fixedly connected to one side of the rotating shaft. A dustproof plate is hinged to the outer side of the air outlet plate. This utility model has a simple structure, effectively filters and sterilizes the blown-out cold air, providing people with high-quality air. It also effectively prevents water droplets from forming inside the air outlet, ensuring the interior of the air outlet remains dry and clean. It is easy to disassemble, simple and convenient, simplifies operation procedures, saves time and effort, and is suitable for widespread promotion and use.

[0005] While the aforementioned patent incorporates a UV sterilization structure at the air outlet, it suffers from several drawbacks: poor sterilization effectiveness and a small contact area during airflow, hindering efficient sterilization.

[0039] Please see Figure 1-10 As shown, a spiral-shaped air conditioner with built-in ultraviolet sterilization tube includes a strip-shaped air guide plate 2 disposed inside the air outlet 11 of the air conditioner; a second short shaft 10 and a first short shaft 8 are respectively fixedly installed on the left and right sides of the strip-shaped air guide plate 2.

[0040] In specific implementation, the first short shaft 8 and the second short shaft 10 are respectively rotatably mounted with a first end plate 4 and a second end plate 6. The first end plate 4 is fixedly installed on the right side wall of the air conditioner outlet 11, and the second end plate 6 is fixedly installed on the left side wall of the air conditioner outlet 11. A notch 9 is opened along the length direction at the rear side of the strip-shaped air guide plate 2. A spiral ultraviolet sterilization flat tube 3 and a mounting shaft 1 are arranged in the notch 9. The spiral ultraviolet sterilization flat tube 3 is fixedly sleeved onto the cylindrical surface of the mounting shaft 1. An inner end shaft 13 is fixedly installed at the middle of each end of the mounting shaft 1. A first circular hole 801 is opened along the length direction in the middle of the first short shaft 8, and a second circular hole 1001 is opened along the length direction in the middle of the second short shaft 10. The two inner end shafts 13 pass through the first circular hole 801 respectively. The first end plate 4 has a first short shaft 8 and a second short shaft 1001, and the two inner end shafts 13 are rotatably installed with the first short shaft 8 and the second short shaft 10, respectively. The first round hole 801 and the second round hole 1001 are respectively connected to the two inner end shafts 13 with clearance fit. A rotary transmission mechanism is installed on the side wall of the first end plate 4 away from the strip guide plate 2, and the rotary transmission mechanism is connected to the first short shaft 8 and the inner end shaft 13 installed on the first round hole 801. Sterilization can be achieved by the spiral ultraviolet sterilization flat tube 3. Through its spiral design, the contact area of ​​the airflow is increased, and the sterilization effect is improved. Furthermore, the spiral ultraviolet sterilization flat tube 3 is set on the mounting shaft 1. The mounting shaft 1 provides rotation drive. When the airflow passes through, the self-rotation of the spiral ultraviolet sterilization flat tube 3 further improves the contact sterilization effect of the airflow, and the overall sterilization effect is good.

[0041] As a specific technical solution, the spiral ultraviolet sterilization flat tube 3 is composed of a quartz glass shell 301, a circuit board 302, and ultraviolet lamp beads 303. The quartz glass shell 301 is a hollow spiral-shaped sheet structure, and the circuit board 302 is a spiral-shaped plate structure with printed circuits on both sides. The circuit board 302 is disposed in the internal cavity of the quartz glass shell 301. Several evenly distributed ultraviolet lamp beads 303 are installed on both sides of the circuit board 302. The circuit board 302 is also connected to two wires 12 and several ultraviolet lamp beads 303. The circuit printed on the circuit board 302 is electrically connected to two wires 12; the two wires 12 extend into the interior of the mounting shaft 1, and the two wires 12 respectively pass through the cylindrical axes of the two inner shafts 13. A metal conductive head 22 is fixedly installed at the end of the wire 12 away from the circuit board 302, and an insulating pad 21 is fixedly installed at the end of the metal conductive head 22 near the inner shaft 13. The insulating pad 21 is fixedly connected to one end face of the inner shaft 13; the end of the metal conductive head 22 away from the insulating pad 21 has a circular spherical structure.

[0042] A power-conducting component is fixedly installed on one side of the fixed housing 5 and one side of the second end plate 6, and the power-conducting component is electrically connected to the metal conductive head 22. The power-conducting component includes an end sleeve 7 and a metal conductive seat 23 disposed inside the end sleeve 7. The end sleeves 7 of the two power-conducting components are fixedly installed on one side of the fixed housing 5 and one side of the second end plate 6, respectively. A circular spherical concave hole is opened on one side of the metal conductive seat 23. The hole wall of the circular spherical concave hole of the metal conductive seat 23 contacts the circular spherical surface of one end of the metal conductive head 22, and the metal conductive... The base 23 is connected to an external power source via cable 26; an insulating plastic sleeve 24 is fixedly installed on one side of the metal conductive base 23, and a positioning guide hole is provided inside the insulating plastic sleeve 24. A positioning guide rod 25 is connected to the positioning guide hole of the insulating plastic sleeve 24 with clearance fit. One end of the positioning guide rod 25 is fixedly connected to the inner wall of the end sleeve 7; a spring 20 is provided inside the positioning guide hole of the insulating plastic sleeve 24. One end of the spring 20 is fixedly connected to one end of the positioning guide rod 25, and the other end of the spring 20 is fixedly connected to the hole wall of the positioning guide hole;

[0043] Specifically, the cables 26 of the two energized components are respectively connected to the positive and negative terminals of the power supply. A power switch is installed on the power supply to control the power on and off. Through the contact between the metal conductive head 22 and the metal conductive base 23, and the connection of the metal conductive head 22 to the circuit board 302 via the wire 12, all the ultraviolet lamp beads 303 are connected in parallel via the circuit printed on the circuit board 302. It should be noted that a transformer is installed on the circuit board 302 to transform the voltage so that the voltage matches the rated voltage of the ultraviolet lamp beads 303 when energized. In summary, the external power supply, the switch, and all the ultraviolet lamp beads 303 form a parallel circuit through the aforementioned wire 12, cables 26, and circuit board 302. When the switch is closed, all the ultraviolet lamp beads 303 are energized, generating ultraviolet light that passes through the quartz glass shell 301 for sterilization. When the switch is open, the ultraviolet lamp beads 303 are de-energized and sterilization is not performed.

[0044] Furthermore, the energizing component ensures that the UV lamp 303 in the spiral UV sterilization flat tube 3 is continuously energized while the mounting shaft 1 is rotating. In specific implementation, when the mounting shaft 1 rotates, the inner shaft 13 rotates along with it, and the metal conductive head 22 connected to it also rotates. During rotation, the metal conductive head 22 and the metal conductive base 23 are in continuous contact, ensuring energization without hindering rotation. In the energizing component, the spring 20 is in a compressed state, providing pressure for the contact between the metal conductive head 22 and the metal conductive base 23, ensuring the contact effect between the two. At the same time, the insulating plastic sleeve 24 and the positioning guide rod 25 provide a positioning effect, preventing the metal conductive head 22 from separating from the metal conductive base 23.

[0045] like Figure 5 As shown, as a specific technical solution, the rotary transmission mechanism includes a fixed housing 5, a first gear 14, a second gear 15, a first input shaft 16, a third gear 17, a second input shaft 18, and a fourth gear 19. The fixed housing 5 is fixedly installed on the side wall of the first end plate 4 away from the strip-shaped air guide plate 2. The first input shaft 16 and the second input shaft 18 are rotatably installed inside the fixed housing 5, and one end of the first input shaft 16 and one end of the second input shaft 18 both extend to the outside of the fixed housing 5. The fourth gear 19 is fixedly sleeved on the second input shaft 18. The fourth gear 19 is meshed with the second gear 15, and the second gear 15 is fixedly sleeved with the inner end shaft 13 installed on the first circular hole 801; a first gear 14 is fixedly installed at one end of the first short shaft 8, and the first gear 14 is meshed with the third gear 17, which is fixedly sleeved on the first input shaft 16; the first input shaft 16 and the second input shaft 18 are used to connect to an external power source to provide drive, and a servo motor can be used; through transmission, the rotation of the spiral ultraviolet sterilization flat tube 3 and the rotation of the strip air guide plate 2 are realized, and the rotation of the two do not affect each other.

[0046] like Figures 9 to 10 As shown, the number of built-in ultraviolet sterilization tubes in the air conditioner is several, and these tubes are arranged vertically at equal intervals inside the air conditioner outlet 11. The top of the spiral ultraviolet sterilization flat tube 3 of the uppermost built-in ultraviolet sterilization tube 3 inside the air conditioner outlet 11 is in close contact with the inner wall of the top of the air conditioner outlet 11, and the bottom of the spiral ultraviolet sterilization flat tube 3 of the lowermost built-in ultraviolet sterilization tube 3 is in close contact with the inner wall of the bottom of the air conditioner outlet 11. The spiral ultraviolet sterilization flat tubes 3 of two adjacent built-in ultraviolet sterilization tubes are in close contact with each other. When the built-in ultraviolet sterilization tubes in this application are used inside the air conditioner outlet 11 as a structure for air guiding and sterilization, multiple sets of built-in ultraviolet sterilization tubes are required to achieve sterilization through their cooperation. At the same time, the above-mentioned close contact design is used to reduce the gap and ensure that the airflow has good contact with the spiral ultraviolet sterilization flat tube 3.

[0047] Usage method: The spiral-shaped air conditioner built-in ultraviolet sterilization tube proposed in this application is installed inside the air conditioner outlet 11. The air guide plate at the air conditioner outlet 11 has been modified so that it does not occupy any extra space inside the air conditioner. In addition to providing air guidance for the air conditioner outlet 11, it can also achieve sterilization through the spiral ultraviolet sterilization flat tube 3. Its spiral design increases the contact area of ​​the airflow and improves the sterilization effect.

[0048] Furthermore, the spiral ultraviolet sterilization flat tube 3 is set on the mounting shaft 1, and the mounting shaft 1 provides rotation drive. When the airflow passes through, the self-rotation of the spiral ultraviolet sterilization flat tube 3 further improves the contact sterilization effect of the airflow, and the overall sterilization effect is better.

[0049] The external drive source is installed through the rotary transmission mechanism, and the drive is transmitted through the rotary transmission mechanism. The strip guide plate 2 can be driven to rotate around the first short axis 8 and the second short axis 10 as the rotation center, which can realize the up and down air sweeping and the up and down air blowing direction adjustment of the airflow of the air conditioner outlet 11. The rotation of the spiral ultraviolet sterilization flat tube 3 is driven to improve the sterilization effect.

[0050] In specific implementation, such as Figures 9 to 10 As shown, when the air conditioner built-in ultraviolet sterilization tube in this application is used inside the air conditioner outlet 11 as a structure for air guiding and sterilization, it needs to be equipped with multiple sets of air conditioner built-in ultraviolet sterilization tubes. The multiple sets of air conditioner built-in ultraviolet sterilization tubes are arranged at equal intervals along the vertical direction. At the same time, the spiral ultraviolet sterilization flat tubes 3 of adjacent air conditioner built-in ultraviolet sterilization tubes are in close contact with each other. The top of the spiral ultraviolet sterilization flat tube 3 of the air conditioner built-in ultraviolet sterilization tube at the top of the air conditioner outlet 11 is in close contact with the inner wall of the top of the air conditioner outlet 11, and the bottom of the spiral ultraviolet sterilization flat tube 3 of the air conditioner built-in ultraviolet sterilization tube at the bottom of the air conditioner outlet 11 is in close contact with the inner wall of the bottom of the air conditioner outlet 11. Through this design, the gap is reduced, ensuring that the airflow and the spiral ultraviolet sterilization flat tube 3 have good contact.

[0051] When the airflow passes through the air conditioner outlet 11, it first passes through the spiral ultraviolet sterilization flat tube 3. The airflow contacts the surface of the spiral ultraviolet sterilization flat tube 3, and its spiral design improves the contact and irradiation area. The cables 26 of the two power-conducting components are respectively connected to the positive and negative terminals of the power supply. Furthermore, a power switch is set on the power supply to control the power on and off. Through the contact between the metal conductive head 22 and the metal conductive base 23, and the fact that the metal conductive head 22 is connected to the circuit board 302 through the wire 12, and then through the circuit printed on the circuit board 302, the airflow is irradiated. Some UV lamps 303 are connected in parallel. It should be noted that a transformer is installed on the circuit board 302 to transform the voltage so that the voltage meets the rated voltage of the UV lamps 303 when energized. In summary, the external power supply, switch and all UV lamps 303 are connected in parallel through the above-mentioned wires 12, cables 26 and circuit board 302 to form a parallel circuit. When the switch is closed, all UV lamps 303 are energized and ultraviolet light is generated. It can be sterilized by passing through the quartz glass shell 301. When the switch is opened, the UV lamps 303 are de-energized and sterilization is not performed.

[0052] After sterilization, the airflow is guided by the strip guide plate 2 and then discharged. The airflow guidance adjustment is achieved by an external power source through a rotary transmission mechanism. Specifically, a power source, which can be a servo motor, is connected to both the first input shaft 16 and the second input shaft 18. The power source drives the first input shaft 16 to rotate. By driving the first input shaft 16 to rotate in the forward and reverse directions, the first short shaft 8 can be rotated in the forward and reverse directions through the meshing transmission of the first gear 14 and the third gear 17. Combined with the rotational installation design of the second short shaft 10 on the strip guide plate 2, the forward and reverse rotation of the strip guide plate 2 is realized, and the up and down blowing direction of the airflow can be adjusted. Continuous forward and reverse rotation can also realize up and down sweeping.

[0053] When the second input shaft 18 is driven to rotate by the power source, the inner shaft 13 is rotated through the meshing transmission of the fourth gear 19 and the second gear 15. When the inner shaft 13 rotates, the mounting shaft 1 rotates together, so that the spiral ultraviolet sterilization flat tube 3 on the mounting shaft 1 also rotates together. Through continuous rotation, a better contact effect is provided for the airflow, ensuring the sterilization effect.

[0054] The rotation adjustment of the inner end shaft 13 and the strip guide plate 2 is independent of each other and does not affect each other. The spiral ultraviolet sterilization flat tube 3 does not rotate, while the strip guide plate 2 rotates to realize the air sweeping and air blowing guidance of the airflow. Alternatively, the spiral ultraviolet sterilization flat tube 3 rotates, while the air guiding position of the strip guide plate 2 is fixed.

[0055] The energizing component ensures that the UV lamp 303 in the spiral UV sterilization tube 3 remains continuously energized while the mounting shaft 1 rotates. Specifically, when the mounting shaft 1 rotates, the inner shaft 13 rotates along with it, and the connected metal conductive head 22 also rotates. During rotation, the metal conductive head 22 and the metal conductive base 23 are in continuous contact, ensuring energization without hindering rotation. In the energizing component, the spring 20 is compressed, providing pressure for the contact between the metal conductive head 22 and the metal conductive base 23, ensuring effective contact. Simultaneously, the insulating plastic sleeve 24 and the positioning guide rod 25 provide positioning, preventing the metal conductive head 22 from detaching from the metal conductive base 23.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
