[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1 to 3 As shown, this utility model embodiment provides a duct air conditioner, including: Indoor unit 100, the indoor unit 100 has a housing and at least one air outlet 102 for supplying air to the room; Fragrance component 104 is installed on one side of the housing. Fragrance component 104 includes air pump 106, atomizing core and essential oil bottle 108. Air pump 106 and essential oil bottle 108 are connected to atomizing core. Fragrance component 104 also has fragrance outlet. Fragrance outlet is connected to air outlet 102 of indoor unit 100 through fragrance tube 110 to deliver fragrance particles generated by atomization of atomizing core to air outlet 102.

[0024] According to the ducted air conditioner provided in this embodiment, the air conditioning airflow of the indoor unit 100 serves as a fragrance diffusion carrier. The air conditioning airflow can cover every corner of the room, and fragrance particles diffuse synchronously with the airflow, ensuring uniform fragrance concentration and diffusion range in different locations within the room, making it particularly suitable for large indoor spaces. The fragrance particles can diffuse rapidly under the influence of the air conditioning airflow, stabilizing the indoor fragrance concentration in a short time without requiring a long wait, thus meeting users' immediate fragrance needs. Simultaneously, the fragrance component 104 is independently installed on one side of the indoor unit 100 casing, without interfering with the core functions of the air conditioner such as temperature regulation and airflow delivery, and will not cause a decrease in the cooling or heating efficiency of the air conditioner due to the operation of the fragrance component 104.

[0025] Please continue reading Figures 1 to 3 The duct air conditioner provided in this embodiment combines the indoor unit 100 with the fragrance component 104 to integrate fragrance diffusion with air conditioning, thus solving the problems of small and uneven diffusion range of traditional fragrance products.

[0026] Specifically, the indoor unit 100 is an embedded or wall-mounted air conditioner indoor unit that delivers conditioned air to the room through the air outlet 102. Its casing is made of metal or high-strength plastic and has enough space to accommodate internal air conditioning components (such as evaporator and fan), while also providing an installation reference for the fragrance component 104.

[0027] The housing has a pre-drilled mounting interface for the fragrance component 104 (such as bolt fixing holes or clip slots) to ensure that the fragrance component 104 can be stably fixed without interfering with the operation of the internal components of the air conditioner.

[0028] Air outlet 102 is located on the front or side of the housing, with at least one outlet, and is equipped with air guide vanes inside. Air outlet 102 is not only used to deliver air conditioning airflow, but also serves as a channel for mixing and diffusion of fragrance particles and airflow. Its duct size and shape are adapted to the access of fragrance tube 110 to ensure that fragrance particles can enter smoothly and mix with airflow.

[0029] The fragrance component 104 has a modular structure and is installed on one side of the indoor unit 100 housing. It has no direct contact with the internal components of the air conditioner. It is connected to the air outlet 102 through the fragrance diffuser tube 110. The fragrance component 104 is used to generate fragrance particles and deliver the fragrance particles to the air outlet 102 of the air conditioner.

[0030] The air pump 106 provides a power source for fragrance atomization. The air pump 106 is connected to the atomizing core through an air tube and can output a stable airflow, providing the necessary airflow conditions for the atomization process.

[0031] The essential oil bottle 108 stores aromatherapy essential oils (such as lavender, lemon, etc.); the essential oil bottle 108 is connected to the liquid absorption structure of the atomizing core through a conduit, which can stably supply essential oils to the atomizing core, and the essential oil bottle 108 also has a leak-proof structure to prevent essential oil leakage from contaminating the air conditioning components.

[0032] The atomizing core integrates liquid absorption and atomization functions. The liquid absorption structure draws essential oil from the essential oil bottle 108, and the atomization structure disperses the essential oil into tiny fragrance particles under the airflow of the air pump 106. The atomizing core also has a fragrance outlet, which is connected to the air outlet 102 of the indoor unit 100 through the fragrance diffuser tube 110 to form a fragrance particle delivery channel.

[0033] The diffuser tube 110 is a flexible or rigid conduit. One end of the diffuser tube 110 is connected to the fragrance outlet of the fragrance component 104, and the other end of the diffuser tube 110 extends into the internal air duct of the air outlet 102. The length and bending angle of the diffuser tube 110 are adapted to the positional relationship between the housing and the air outlet 102 to avoid poor fragrance delivery caused by the bending of the conduit.

[0034] In actual use, when the fragrance component 104 is turned on, the air pump 106 starts to work and delivers a stable airflow to the atomizing core; the liquid absorption structure of the atomizing core draws essential oil from the essential oil bottle 108, and the essential oil is atomized into tiny fragrance particles under the action of the airflow; the fragrance particles are propelled by the airflow and enter the diffuser tube 110 from the fragrance outlet of the fragrance component 104.

[0035] The fragrance diffuser tube 110 delivers fragrance particles to the internal air duct of the air outlet 102 of the indoor unit 100; at the same time, the indoor unit 100 simultaneously delivers air conditioning airflow, and the fragrance particles are fully mixed with the air conditioning airflow in the air outlet 102 air duct; the air conditioning airflow mixed with fragrance particles is sent into the room through the air outlet 102, and diffuses to various areas of the room with the airflow to achieve uniform fragrance coverage.

[0036] When the fragrance component 104 is turned off, the air pump 106 stops working, and the fragrance generation and delivery cease. When the essential oil in the essential oil bottle 108 is exhausted, the essential oil bottle 108 can be removed for replacement without disassembling the entire fragrance component 104 or the indoor unit 100.

[0037] According to one embodiment of the present invention, the indoor unit 100 further includes an electrical control box 112, and the fragrance component 104 is disposed adjacent to the electrical control box 112 and electrically connected to the electrical control box 112.

[0038] In one embodiment of this utility model, the electrical control box 112 is a rectangular metal box, fixed inside the housing of the indoor unit 100 near the edge. It integrates the air conditioning operation control circuit and also provides power and signal interfaces for the fragrance component 104. The fragrance component 104 is connected to the reserved interface of the electrical control box 112 via a wire, eliminating the need for an additional independent power supply line. On one hand, the electrical control box 112 provides a stable power supply for the air pump 106, atomizing core, and other components of the fragrance component 104. On the other hand, a signal transmission channel is established between the electrical control box 112 and the fragrance component 104, enabling real-time sending of control commands such as start / stop and mode switching.

[0039] The fragrance component 104 is installed adjacent to the electrical control box 112, which shortens the wire length to reduce signal attenuation and power loss, and avoids the messy installation caused by the fragrance component 104 being far away from the electrical control box 112.

[0040] With the above setup, there is no need to configure a separate power adapter or wiring for the fragrance component 104. Power supply and control are achieved using the existing electrical control box 112 of the indoor unit 100, reducing the number of components, lowering installation complexity, and avoiding the difficulties in later maintenance caused by multiple intersecting lines. The electrical control box 112 can synchronously coordinate the operating status of the air conditioner and the fragrance component 104, avoiding energy waste caused by the fragrance component 104 operating alone, improving user convenience, and eliminating the need to operate two devices separately.

[0041] According to one embodiment of the present invention, the atomizing core is provided with a liquid suction channel and a jet spray channel. The liquid suction channel is in fluid communication with the essential oil bottle 108, and the jet spray channel is in fluid communication with the air pump 106. The outlet of the jet channel is located adjacent to the outlet of the liquid suction channel. The high-speed airflow ejected from the jet channel is suitable for generating negative pressure at the outlet of the liquid suction channel to draw out and atomize the essential oil in the essential oil bottle 108.

[0042] In one embodiment of this utility model, the atomizing core is a cylindrical metal or ceramic component, with a liquid absorption channel and an air jet channel arranged in parallel along the axial direction inside: the liquid absorption channel is a slender hole with a flexible liquid absorption core attached to its inner wall, one end of the liquid absorption core extending into the essential oil bottle 108 to continuously absorb essential oil through capillary action, and the other end extending to the outlet of the liquid absorption channel; the air jet channel is a through hole with a diameter slightly larger than that of the liquid absorption channel, one end of which is connected to the air pump 106 through an air tube, and the other end outlet is adjacent to the outlet of the liquid absorption channel on the end face of the atomizing core.

[0043] When the air pump 106 is started, a high-speed airflow is ejected from the jet channel outlet, creating a negative pressure area at the outlet of the adjacent liquid absorption channel. The negative pressure draws the essential oil in the liquid absorption channel to the outlet end. At the same time, the high-speed airflow impacts the drawn-out essential oil, breaking it down into tiny fragrance particles, achieving the integration of liquid absorption and atomization without the need for additional heating or ultrasonic devices.

[0044] Compared to traditional ultrasonic atomization or heating atomization, negative pressure airflow atomization requires no additional consumables and atomizes essential oils thoroughly with no residue or waste. At the same time, the atomization process does not generate high temperatures, which can preserve the active ingredients in the essential oils and ensure that the fragrance effect is not compromised.

[0045] According to one embodiment of the present invention, an air pipe is provided between the air pump 106 and the air jet channel, and an electromagnetic valve for controlling the opening and closing of the air pipe is installed on the air pipe.

[0046] In one embodiment of this utility model, the air tube is a flexible silicone tube with a smooth inner wall to reduce airflow resistance. One end is interference-fitted onto the air outlet of the air pump 106, and the other end is connected to the inlet of the atomizing core's jet channel. The connection is secured with a clamp to prevent detachment or leakage due to airflow pressure. The solenoid valve is a miniature electromagnetic control valve, installed in series in the middle of the air tube. The valve body is fixed to the inner wall of the fragrance component 104's outer shell by a bracket to prevent the solenoid valve from shifting due to air tube movement.

[0047] The control terminal of the solenoid valve is connected to the electrical control box 112 via a wire, receiving on / off commands from the electrical control box 112: when energized, the solenoid valve core opens, the air path is opened, and high-speed airflow enters the jet channel; when de-energized, the valve core closes, the air path is cut off, and the atomization process stops. The solenoid valve has a one-way sealing function to prevent essential oil vapor or airflow from flowing back into the air pump 106, protecting the internal components of the air pump 106 from corrosion.

[0048] Compared to controlling atomization by starting and stopping the air pump 106, the solenoid valve can instantly open and close the air path, enabling the fragrance to be turned on or off immediately. This avoids the lifespan loss caused by frequent starting and stopping of the air pump 106, while also meeting the user's need for on-demand use.

[0049] According to one embodiment of the present invention, the electrical control box 112 is electrically connected to the air pump 106 and the solenoid valve, and the electrical control box 112 is used to control the start and stop of the fragrance component 104 and the fragrance concentration.

[0050] In one embodiment of this utility model, the electrical control box 112 is equipped with a fragrance control module, which is connected to the control terminals of the air pump 106 and the solenoid valve respectively through wires: when controlling the start and stop, the electrical control box 112 sends a power supply signal to the air pump 106 and a conduction signal to the solenoid valve, and the two work together to start atomization; when shutting down, the power supply to the air pump 106 and the conduction signal to the solenoid valve are cut off simultaneously, and atomization is terminated.

[0051] When controlling the fragrance concentration, the electrical control box 112 adjusts it in two ways: one is to adjust the intensity of the airflow output by the air pump 106, and the other is to control the intermittent on / off frequency of the solenoid valve. The two adjustment methods can be combined through the program logic of the electrical control box 112 to achieve multi-level concentration switching. The concentration level can be selected through the control panel of the indoor unit 100 or the remote control.

[0052] Users can adjust the fragrance concentration according to the needs of the scene, avoiding the discomfort caused by the fixed concentration of traditional aromatherapy products, improving the flexibility of the user experience, and adapting to the olfactory preferences of different groups of people.

[0053] According to one embodiment of the present invention, the end of the aroma diffuser tube 110 is formed with an aroma outlet 114, which extends into the internal air duct of the air outlet 102.

[0054] In one embodiment of this utility model, the diffuser tube 110 is a rigid plastic tube, and the length of the tube body is adapted to the distance between the fragrance component 104 and the air outlet 102 to avoid excessive bending that would cause poor fragrance delivery. The end of the diffuser tube 110 is designed with a bevel, and the outer wall of the fragrance outlet 114 is provided with an elastic sealing sleeve. When it is inserted into the air duct inside the air outlet 102, the sealing sleeve fits tightly against the inner wall of the air duct to prevent fragrance particles from leaking into the housing from the gaps.

[0055] The depth to which the fragrance outlet 114 extends into the air duct is based on the premise of not interfering with the rotation of the air guide vanes, and the opening is directly facing the direction of the mainstream airflow in the air duct, ensuring that the fragrance particles can be quickly carried away by the air conditioning airflow and avoid stagnation and settling in the air duct.

[0056] The fragrance outlet 114 extends into the air duct, allowing fragrance particles to directly enter the mainstream area of ​​the air conditioning airflow without passing through the outer space of the casing. This avoids the loss of fragrance particles due to diffusion and sedimentation during transportation, ensuring that the fragrance particles generated by atomization can diffuse into the room to the greatest extent with the air conditioning airflow.

[0057] According to one embodiment of the present invention, the interior of the air outlet 102 is configured to form a mixing zone, in which fragrance particles discharged through the fragrance outlet 114 are mixed with the air conditioning airflow delivered by the indoor unit 100.

[0058] In one embodiment of this utility model, the middle section of the air duct inside the air outlet 102 is designed as a mixing zone: the inner wall of the air duct in this zone is provided with annular protrusions or guide ribs, which are spiral or inclined. When the air conditioning airflow passes through the mixing zone, the guide ribs change the airflow direction, causing the airflow to rotate or become turbulent. The opening end of the fragrance outlet 114 is located at the center of the mixing zone. After the fragrance particles are discharged from the fragrance outlet 114, they directly enter the rotating or turbulent airflow.

[0059] The cross-sectional area of ​​the air duct in the mixing zone is slightly larger than that of other areas of the air outlet 102, which prolongs the contact time between the airflow and the fragrance particles, ensuring that the rotating airflow drives the fragrance particles to be evenly dispersed, avoiding local accumulation of fragrance particles. The mixed airflow is then transported to the room through the air guide vanes of the air outlet 102.

[0060] The turbulent or rotating airflow in the mixing zone breaks the aggregation of fragrance particles, ensuring a consistent mixing ratio between the fragrance particles and the air conditioning airflow. This results in no significant concentration difference after the fragrance is delivered indoors, making it particularly suitable for the uniform diffusion needs of large spaces.

[0061] According to one embodiment of the present invention, the essential oil bottle 108 is detachably connected to the atomizing core.

[0062] In one embodiment of this utility model, the bottle mouth of the essential oil bottle 108 is provided with an external thread, and the liquid inlet end of the atomizing core is provided with a connecting seat with an internal thread. The two are detachably connected by screwing the threads together. A flexible sealing ring is fitted at the threaded connection. After screwing, the sealing ring is pressed tight to prevent the essential oil from leaking from the gap.

[0063] The essential oil bottle 108 is a transparent cylindrical container with volume markings on the body and anti-slip texture on the bottom. The connector and atomizer core are integrally molded, and an internal guide hole is provided. When the essential oil bottle 108 is screwed on, the absorbent core inside can be precisely inserted into the absorbent channel of the atomizer core through the guide hole without additional alignment adjustments. To disassemble, simply rotate the essential oil bottle 108 in reverse to remove it from the connector. After replacing with a new bottle, repeat the screwing operation to complete the installation.

[0064] The detachable connection between the essential oil bottle 108 and the atomizing core allows users to disassemble and assemble the essential oil bottle 108 simply by rotating it, without having to disassemble the fragrance component 104 or the indoor unit 100. This avoids the complicated replacement process of traditional aromatherapy products, which requires opening the outer shell and pulling out the tube.

[0065] According to one embodiment of the present invention, a maintenance grille is provided on the shell at a position corresponding to the essential oil bottle 108.

[0066] In one embodiment of this utility model, the inspection grille is a rectangular or circular perforated metal mesh plate, which is fixed to the side of the indoor unit 100 housing by clips or bolts, and its position corresponds exactly to the essential oil bottle 108 of the fragrance component 104. The size of the perforated holes of the grille is large enough to observe the remaining essential oil, and the user can directly observe the liquid level in the essential oil bottle 108 through the perforations; at the same time, the edges of the grille are rounded to avoid scratching hands when disassembling and assembling the essential oil bottle 108.

[0067] A rubber sealing strip is provided at the joint between the grille and the housing to ensure that there is no looseness after installation and to prevent noise caused by the grille colliding with the housing when the air conditioner is running. When removing the grille, it can be removed simply by unfastening the clips or unscrewing the bolts, without the need for complicated tools, which facilitates the subsequent maintenance of the essential oil bottle 108 and the fragrance component 104.

[0068] Users can directly observe the remaining amount in the essential oil bottle 108 through the perforated opening of the inspection grille without disassembling any parts, promptly detect when the essential oil is depleted and replace it, avoid interruption of the fragrance due to "the essential oil running out", and improve the convenience of use.

[0069] According to one embodiment of the present invention, the fragrance component 104 further includes a fragrance housing 116, an air pump 106, an atomizing core, and an essential oil bottle 108 housed in the fragrance housing 116.

[0070] In one embodiment of this utility model, the fragrance housing 116 is a rectangular or cylindrical plastic or metal housing with internal partition slots and fixing brackets: the air pump 106 is fixed to one side of the housing by an elastic bracket, the atomizing core is fixed to the mounting seat in the middle of the housing by bolts, and the essential oil bottle 108 is detachably fixed to the other side of the housing by a slot.

[0071] An opening is provided on one side of the outer casing for leading out the diffuser tube 110 and the wire connecting the electrical control box 112; a sealing sleeve is provided at the opening to prevent dust and moisture from entering the interior of the casing and contaminating the components; heat dissipation holes are provided on the surface of the outer casing to ensure that the heat generated during the operation of the air pump 106 can be dissipated in a timely manner. The fragrance outer casing 116 is fixed to one side of the indoor unit 100 casing by bolts or clips. After installation, the surface of the outer casing is flush with or slightly concave to the surface of the indoor unit 100 casing, without protruding to form a protruding structure.

[0072] The fragrance housing 116 integrates the air pump 106, atomizing core, essential oil bottle 108 and other separate components into a single module, avoiding noise caused by vibration and collision between components, while preventing dust and moisture from entering the components, reducing the risk of air pump 106 clogging and atomizing core getting damp, and extending the overall service life of the fragrance component 104.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
