A plurality of fixing brackets 814 are formed on the outer wall of the fragrance holder cylinder 88, through which the fragrance holder cylinder 88 is mounted to the purifying and deodorizing device.

[0033] The fragrance holder cylinder 88 is internally equipped with an essential oil bottle 87 and a fragrance vaporization device 83 that is cooperatively connected with the essential oil bottle 87. The fragrance vaporization device 83 is internally provided with an internal thread 818 and an essential oil return port 819. The fragrance vaporization device 83 is provided with a fragrance cap 81 at its top. The internal thread 818 is configured to secure the essential oil bottle 87. A groove 817 is formed on an outer wall of the fragrance vaporization device 83, and a sealing silicone gasket 84 is fitted in the groove 817 to seal a pump air inlet 815.

[0034] An essential oil connection tube 86 is installed between the essential oil bottle 87 and the fragrance vaporization device 83. The fragrance vaporization device 83 is internally provided with a return bracket 82. The fragrance vaporization device 83 is further internally provided with an air pump inlet 815 and an essential oil outlet 816. A terminal end of the air pump inlet 815 is tapered to form an air outlet hole 821, while the essential oil outlet 816 is tapered to form a vaporization spray nozzle 820. A lower end of the essential oil connection tube 86 is inserted into the essential oil bottle 87, while its upper end is inserted into the essential oil outlet 816. The essential oil outlet 816 is provided with a ramp 822 formed at its top end, with an inclination angle of the ramp 822 being 30 to 60 degrees. The ramp 822 is configured to be completely unobstructed, ensuring that the transmission of airflow is not adversely affected and thereby guaranteeing vaporization performance. The high-pressure air emanating from the air outlet hole 821 is deflected upward as it passes through the ramp 822, thereby generating negative pressure that draws out the essential oil, vaporizes it, and conveys it upward.

[0035] A top surface of the essential oil outlet 816 is provided with a vaporization platform 823. The vaporization platform 823 has a length of 1-3 mm and a width of 1-3 mm, and features as an inclined surface structure. Excessively large or small dimensions of the vaporization platform 823 will adversely affect vaporization performance.

[0036] The air outlet hole 821 has a diameter of 0.2-0.6 mm and a depth of 0.2-0.5 mm. The vaporization spray nozzle 820 has a diameter of 0.2-1 mm and a depth of 0.3-0.6 mm. The distance between the air outlet hole 821 and the vaporization spray nozzle 820 ranges from 0.2 to 1.5 mm. An upper half of the air outlet hole 821 is positioned above a plane of the vaporization spray nozzle 820, while the lower half of the air outlet hole 821 is positioned below the plane of the vaporization spray nozzle 820.

[0037] A raised elastic feature 824 is formed on the vaporization platform 823, positioned to the right of the vaporization spray nozzle 820. A distance between a right edge of the raised elastic feature 824 and a right end of the vaporization spray nozzle 820 ranges from 0.1 to 1 mm. A primary function of the raised elastic feature 824 is to facilitate the smooth retraction of a ejector pin during mold production.

[0038] During operation of the air purifying and deodorizing device incorporating fragrance diffusion according to the present disclosure, the air pump 810 is activated to generate a high-pressure airflow. The high-pressure airflow instantaneously travels through the air pump inlet 815 and reaches the air outlet hole 821. The high-pressure airflow instantaneously changes the pressure at the vaporization spray nozzle 820 as the high-pressure airflow passes through the vaporization spray nozzle 820, thereby creating a negative pressure that draws out essential oil from the essential oil bottle 87 through the essential oil connection tube 86. Upon reaching the vaporization spray nozzle 820, the essential oil is rapidly vaporized by the high-pressure airflow and carried by the air stream into the surrounding air. Compared with existing fragrance modules, the air purifying and deodorizing device incorporating fragrance diffusion according to the present disclosure features a simpler overall structure, more reasonable design, and lower production cost, thereby avoiding damage to essential oil components due to heating, providing better vaporization performance, and better satisfying users' needs.

[0039] According to the above embodiments of the present disclosure, the fragrance assembly 8 is mounted on the top cover 18 of the air purifying and deodorizing device, thereby simplifying maintenance of the fragrance assembly 8. Maintenance of the fragrance assembly 8 is performed without disassembling the air purifying and deodorizing device by simply removing the pet-accessible scratching surface 20 and pulling the fragrance vaporization device 83 upward to extract the essential oil bottle 87. Compared to existing arrangement of fragrance devices, the present disclosure features a simpler structure with easier disassembly and installation. Since the fragrance assembly 8 is mounted on the top cover 18 of the air purifying and deodorizing device and the top cover 18 is an air outlet of the air purifying and deodorizing device, vaporized essential oil generated by the fragrance device 8 disperses rapidly throughout entire interior space as the purified air flows out, thereby allowing liquid deodorizing fragrance to be more effectively integrated into indoor circulation air through internal circulation airflow generated by generated by the air purifying and deodorizing device, more quickly eliminating odors and delivering fragrance in the indoor circulation air.

A plurality of fixing brackets 814 are formed on the outer wall of the fragrance holder cylinder 88, through which the fragrance holder cylinder 88 is mounted to the purifying and deodorizing device.

[0033] The fragrance holder cylinder 88 is internally equipped with an essential oil bottle 87 and a fragrance vaporization device 83 that is cooperatively connected with the essential oil bottle 87. The fragrance vaporization device 83 is internally provided with an internal thread 818 and an essential oil return port 819. The fragrance vaporization device 83 is provided with a fragrance cap 81 at its top. The internal thread 818 is configured to secure the essential oil bottle 87. A groove 817 is formed on an outer wall of the fragrance vaporization device 83, and a sealing silicone gasket 84 is fitted in the groove 817 to seal a pump air inlet 815.

[0034] An essential oil connection tube 86 is installed between the essential oil bottle 87 and the fragrance vaporization device 83. The fragrance vaporization device 83 is internally provided with a return bracket 82. The fragrance vaporization device 83 is further internally provided with an air pump inlet 815 and an essential oil outlet 816. A terminal end of the air pump inlet 815 is tapered to form an air outlet hole 821, while the essential oil outlet 816 is tapered to form a vaporization spray nozzle 820. A lower end of the essential oil connection tube 86 is inserted into the essential oil bottle 87, while its upper end is inserted into the essential oil outlet 816. The essential oil outlet 816 is provided with a ramp 822 formed at its top end, with an inclination angle of the ramp 822 being 30 to 60 degrees. The ramp 822 is configured to be completely unobstructed, ensuring that the transmission of airflow is not adversely affected and thereby guaranteeing vaporization performance. The high-pressure air emanating from the air outlet hole 821 is deflected upward as it passes through the ramp 822, thereby generating negative pressure that draws out the essential oil, vaporizes it, and conveys it upward.

[0035] A top surface of the essential oil outlet 816 is provided with a vaporization platform 823. The vaporization platform 823 has a length of 1-3 mm and a width of 1-3 mm, and features as an inclined surface structure. Excessively large or small dimensions of the vaporization platform 823 will adversely affect vaporization performance.

[0036] The air outlet hole 821 has a diameter of 0.2-0.6 mm and a depth of 0.2-0.5 mm. The vaporization spray nozzle 820 has a diameter of 0.2-1 mm and a depth of 0.3-0.6 mm. The distance between the air outlet hole 821 and the vaporization spray nozzle 820 ranges from 0.2 to 1.5 mm. An upper half of the air outlet hole 821 is positioned above a plane of the vaporization spray nozzle 820, while the lower half of the air outlet hole 821 is positioned below the plane of the vaporization spray nozzle 820.

[0037] A raised elastic feature 824 is formed on the vaporization platform 823, positioned to the right of the vaporization spray nozzle 820. A distance between a right edge of the raised elastic feature 824 and a right end of the vaporization spray nozzle 820 ranges from 0.1 to 1 mm. A primary function of the raised elastic feature 824 is to facilitate the smooth retraction of a ejector pin during mold production.

[0038] During operation of the air purifying and deodorizing device incorporating fragrance diffusion according to the present disclosure, the air pump 810 is activated to generate a high-pressure airflow. The high-pressure airflow instantaneously travels through the air pump inlet 815 and reaches the air outlet hole 821. The high-pressure airflow instantaneously changes the pressure at the vaporization spray nozzle 820 as the high-pressure airflow passes through the vaporization spray nozzle 820, thereby creating a negative pressure that draws out essential oil from the essential oil bottle 87 through the essential oil connection tube 86. Upon reaching the vaporization spray nozzle 820, the essential oil is rapidly vaporized by the high-pressure airflow and carried by the air stream into the surrounding air. Compared with existing fragrance modules, the air purifying and deodorizing device incorporating fragrance diffusion according to the present disclosure features a simpler overall structure, more reasonable design, and lower production cost, thereby avoiding damage to essential oil components due to heating, providing better vaporization performance, and better satisfying users' needs.

[0039] According to the above embodiments of the present disclosure, the fragrance assembly 8 is mounted on the top cover 18 of the air purifying and deodorizing device, thereby simplifying maintenance of the fragrance assembly 8. Maintenance of the fragrance assembly 8 is performed without disassembling the air purifying and deodorizing device by simply removing the pet-accessible scratching surface 20 and pulling the fragrance vaporization device 83 upward to extract the essential oil bottle 87. Compared to existing arrangement of fragrance devices, the present disclosure features a simpler structure with easier disassembly and installation. Since the fragrance assembly 8 is mounted on the top cover 18 of the air purifying and deodorizing device and the top cover 18 is an air outlet of the air purifying and deodorizing device, vaporized essential oil generated by the fragrance device 8 disperses rapidly throughout entire interior space as the purified air flows out, thereby allowing liquid deodorizing fragrance to be more effectively integrated into indoor circulation air through internal circulation airflow generated by generated by the air purifying and deodorizing device, more quickly eliminating odors and delivering fragrance in the indoor circulation air.
