Description

Technical Field

[0001] The present invention relates to the technical field of cooling and heating equipment, and in particular to a cooling and heating micro-control conversion device. Background Art

[0002] Existing heating devices, such as PTC or heating wire heating products, can only be used in specific spaces. If the space is too large, achieving the required temperature requires a very high power output, posing reliability and safety risks (e.g., a living room). If the space is too small, the product's inherent requirements cannot be met, making it smaller, making it unusable in some small, localized spaces (e.g., a chair). Heating wires operate on the same principle as other metal heating elements: the phenomenon of electrothermal heating when electricity is applied to metal. Electrothermal heating refers to the process by which current flows through a conductor, generating a certain amount of heat that is then transferred. Heating wires are metal conductors, emitting heat and providing thermal energy upon application. However, their heating range is limited, they consume oxygen, and their safety, waterproofness, and thermal efficiency are all low, resulting in a short lifespan. Therefore, both PTC and heating wire heating devices are difficult to manufacture in miniaturized form, making it difficult to achieve the desired comfort in certain areas or specific spaces where people work and live. Regarding cooling, compressor refrigeration systems face difficulties starting at low temperatures, low heating efficiency in winter, vibration sensitivity, and the inability to tilt or invert them, all of which are significant product drawbacks. Furthermore, system maintenance requires pyrotechnics to replace damaged components. When encountering damaged components and pipes, the refrigerant must be drained before pyrotechnics can be performed, which results in considerable waste. Prior art miniature air conditioners designed with semiconductor cooling or heating elements have only one active air outlet and one inactive air outlet. This means the cold air outlet can only discharge cold air, while the hot air outlet can only discharge hot air. The hot and cold air outlets cannot be switched, preventing the active outlet from discharging cold air when needed and hot air when needed. Therefore, a micro-controllable heating and cooling conversion device is needed to address these issues. Summary of the Invention

Different air volumes and wind directions can be selected after switching the conversion parts, and different comfort levels can be selected according to actual conditions.

[0043] The working principle of the cooling and heating micro-control conversion device of the present invention is as follows:

[0044] By rotating the three conversion parts, the three sleeves 14 rotate around the axis 16 with the axis 16 as the center under the action of the beam, and the first air cover 15.1 is sleeved on the effective air outlet 8, and rotates to the corresponding position of the air outlet assembly with the effective air outlet 8. The effective air outlet 8 and the invalid air outlet are designed as an integrated whole. The end side surfaces of the effective air outlet 8 and the invalid air outlet close to the air outlet assembly are sleeved with the sleeve 14 and are slidably connected to the sleeve 14. By squeezing the effective air outlet 8 and the invalid air outlet, the conversion part slides one end distance relative to the sleeve 14 toward the air outlet assembly. Under the action of the protrusion 10.3, the first spring 10.2, the groove 10.1 and the through hole 5.1, the conversion part is detachably connected to the air outlet assembly, such as Figure 1The hot air duct 5 is connected to the second invalid air outlet 10, and the hot air duct 5 is connected to the second invalid air outlet 10. The effective air outlet 8 is connected to the first invalid air outlet 9 by the second partition plate 18. The rotating part and the air outlet assembly are disassembled by the protrusion 10.3, the first spring 10.2, the groove 10.1 and the through hole 5.1. At the same time, the rotating part rotates 180 degrees under the action of the sleeve body 14, and the first invalid air outlet 9 and the second invalid air outlet 10 are switched. At the same time, the rotating part and the air outlet assembly are connected and fixed again by the protrusion 10.3, the first spring 10.2, the groove 10.1 and the through hole 5.1. The outward extrusion force of the second spring 13 can make the connection between the rotating part and the air outlet assembly more tightened. At this time, the hot air channel is connected to the effective air outlet 8, and the cold air channel is connected to the second invalid air outlet 10. The switching of cold air and hot air in the effective air outlet 8 is achieved by rotating the rotating part 180 degrees under the action of the sleeve body 14.

[0045] Reference Figure 6 The first wind shield 15.1 is hinged with two first horizontal fan blades 15.1.2 and the first vertical fan blade 15.1.1 through the first vertical fan blade 15.1.1. The first wind shield 15.1 can be swung left and right by the two first horizontal fan blades 15.1.2 to drive the first vertical fan blade 15.1.1 to swing left and right to discharge air, thereby expanding the range of effective wind discharge directions.

[0046] Reference Figure 7-8 , after switching to the second wind cover 15.2, by sliding the slider 15.2.2 on the vertical rod 11, the connecting rod 15.2.4 is driven to move up and down, thereby driving the two second horizontal fan blades 15.2.3 to swing in the same direction at the same time, thereby achieving effective adjustment to the same side of the air outlet 8 direction. At the same time, several vertical rods 11 are arranged at the front end of the second horizontal fan blade 15.2.3, which can further divert the wind at the air outlet.

[0047] Reference Figure 9 After switching to the third wind shield 15.3, the first rotating ring 15.3.1 is swung on the second rotating ring 15.3.2 by rotating the first rotating ring 15.3.1, and the wind hole 15.3.3 on the first rotating ring 15.3.1 is adjusted at multiple angles by rotating the second rotating ring 15.3.2.
