Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fragrance generator, specifically, and relates to a multi-air duct fragrance generator based on one-way rotation structure. BACKGROUND

[0002] Fragrance generators are gradually popular in smart home, vehicle-mounted environment and other scenes, and users' demand for multi-fragrance switching and multi-zone independent air supply function is increasing. In traditional technology, in order to realize independent control of different air ducts, a driving motor needs to be configured for each air duct, and the opening and closing of the air door are controlled through forward and reverse rotation or start and stop operation of the motor.

[0003] However, such design has obvious deficiencies: the use of multiple motors greatly increases the hardware cost and system size, which is difficult to deploy in a space-limited vehicle-mounted environment; at the same time, the coordinated control of multiple motors needs to rely on complex circuit design, which not only increases the overall power consumption of the system, but also easily causes errors due to the response difference of the motors, affecting the timeliness and accuracy of fragrance switching. Therefore, how to realize reliable control of multiple air ducts under the single-motor architecture while considering the requirements of low cost, low power consumption and miniaturization is still a core problem that needs to be solved in the field.

[0004] The patent document with publication number CN214911034U discloses a multi-water tank aromatherapy machine, which includes a base, a plurality of air ducts formed in the base, each air duct having an air inlet and an air outlet, the air outlet being located at the top of the base, a plurality of atomizing water tanks, each atomizing water tank being placed on the base, each atomizing water tank having an atomizing cavity, each atomizing water tank having an air inlet and a mist outlet communicating with the atomizing cavity, each air inlet being in communication with the corresponding air outlet, and a plurality of fans, each fan being arranged in the corresponding air duct and located at the position of the corresponding air outlet. Although this scheme can meet the different aromatherapy needs of users at different times or in different environments to some extent, it does not provide a fragrance switching device, but uses multiple atomizing water tanks and fans regularly, which may cause high power consumption and high cost.

[0067] The utility model discloses a multi -wind channel fragrance generator based on one -way rotation structure, as shown in Figure 5 The utility model discloses a multi -wind channel fragrance generator based on one -way rotation structure, as shown in

[0068] The blade cover 4 includes a top plate 404 and an air duct baffle 405 installed at the bottom of the top plate 404. The air duct baffle 405 divides the space between the blade cover 4 and the mixing chamber cover 3 into an air outlet chamber 402 and an air inlet chamber 403. The blade cover air duct opening 401 includes a first blade cover air duct opening communicating with the air outlet chamber 402 and a second blade cover air duct opening communicating with the air inlet chamber 403. The first blade cover air duct opening and the second blade cover air duct opening are located inside and outside the air duct baffle 405, respectively. The air duct baffle 405 is vertically installed at the bottom of the blade cover 4, dividing the space between the blade cover 4 and the mixing chamber cover 3 into an air inlet chamber 403 and an air outlet chamber 402. The air inlet chamber introduces external air through the air inlet 102, and the air outlet chamber discharges the air mixed with fragrance through the fan 2, forming a unidirectional circulating airflow.

[0069] The fan 2 includes a fan inlet at the bottom and a fan outlet 201 on the side; the fan inlet is connected to the air outlet 402 through a through hole in the middle of the mixing chamber cover 3, and the fan outlet 201 is connected to the air outlet 101; when the fan 2 is started, air enters the air inlet 403 through the air inlet 102, passes through the second blade cover air duct to the fragrance cartridge 18 installation location, and passes through the first blade cover air duct, the air outlet 402, the fan inlet, the fan outlet 201 and the air outlet 101 in sequence to reach the outside of the housing.

[0070] Through the internal air path design, when the fan 2 is running, external air enters the air inlet chamber 403 from the air inlet 102, flows through the air duct of the second blade cover and passes through the fragrance bomb 18 to adsorb fragrance molecules, and then enters the air outlet chamber 402 through the air duct of the first blade cover. Finally, it is drawn in by the fan inlet, pressurized and discharged from the air outlet 101, forming a closed-loop high-efficiency circulation.

[0071] like Figure 7 As shown, a duct cover 5 is installed on the top of the blade cover 4; a blade mounting groove corresponding to the blade 6 is installed at the bottom of the duct cover 5, and the blade 6 is rotatably installed in the blade mounting groove. The blade mounting groove is provided with a through hole corresponding to the duct opening 401 of the blade cover. In the closed state, the blade 6 rotates to abut against the first side wall of the blade mounting groove, and the blade 6 covers the duct opening 401 of the blade cover. In the open state, the blade 6 rotates to abut against the second side wall of the blade mounting groove, and the blade 6 does not cover the duct opening 401 of the blade cover.

[0072] When the blade 6 rotates, it is mechanically limited by the first side wall of the blade mounting groove being closed or the second side wall being open. The blade 6 is forced to stop at a set angle by physical obstruction, completely covering or exposing the air duct opening 401 of the blade cover, realizing reliable switching of the air duct opening and closing state. The blade mounting groove and side wall limiting design ensure accurate blade opening and closing action, avoiding air leakage or malfunction caused by mechanical clearance.

[0073] The first one-way rotation structure and the second one-way rotation structure each comprise a one-way bearing 7 coaxially installed inside the blade 6 and in transmission connection with the output shaft of the motor 14. The inner ring of the one-way bearing 7 is fixed with the output shaft of the motor, and the outer ring is connected with the blade 6. When the rotation direction of the motor is consistent with the transmission direction allowed by the one-way bearing, the torque is transmitted to the blade 6 through the bearing; when the rotation direction is reversed, the bearing idles and the blade 6 remains stationary.

[0074] The output shaft of the motor 14 is coaxially installed with a driving wheel 9, and the bottom of the blade 6 is coaxially installed with a driven wheel 8, which is in meshing connection with the driving wheel 9. When the driving wheel 9 rotates with the motor shaft, it engages and drives the blade 6 to rotate, ensuring stable power transmission.

[0075] The first seal 10 and the NFC module 11 are installed between the fragrance spring fixing member and the air duct cover 5. The NFC module 11 is installed at the bottom of the fragrance spring fixing member and is in electrical connection with the motor 14. The top edge of the first seal 10 abuts against the bottom edge of the fragrance spring fixing member, and the bottom edge of the first seal 10 abuts against the top edge of the air duct cover 5. The first seal 10 is provided with a first seal air duct opening 1001 and a second seal air duct opening 1002, which correspond to the first fixing member air duct opening 1201 and the second fixing member air duct opening 1202 of the fragrance spring fixing member, respectively, and are used for communication with the internal space of the fragrance spring fixing member. The first seal air duct opening 1001 communicates with the air inlet cavity 403 through the blade cover air duct opening 401, and the second fixing member air duct opening 1202 communicates with the air outlet cavity 402 through the blade cover air duct opening 401.

[0076] The first seal air duct opening 1001, the second seal air duct opening 1002, the first fixing member air duct opening 1201, and the second fixing member air duct opening 1202 are aligned to form a sealed channel, preventing the escape of fragrance gas. The NFC module 11 can read the chip information in the fragrance spring 18, feedback the remaining capacity, and trigger the motor 14 action logic, thereby realizing signal transmission of the fragrance spring 18 information and remote control of the switching action.

[0077] The fragrance spring fixing member includes an upper fragrance spring fixing member 12 and a lower fragrance spring fixing member 15 installed at the bottom of the upper fragrance spring fixing member 12; the bottom middle of the upper fragrance spring fixing member 12 is provided with a motor mounting portion for mounting a motor 14, and the two sides of the motor mounting portion are upper fragrance spring mounting portions for mounting fragrance springs 18; the two sides of the lower fragrance spring fixing member 15 are provided with lower fragrance spring mounting portions corresponding to the upper fragrance spring mounting portions, and the upper fragrance spring mounting portions and the lower fragrance spring mounting portions form a closed cavity, and the fragrance spring 18 is located in the closed cavity; the top of the closed cavity is provided with a first fixing member air duct opening 1201 for respectively communicating with an air outlet cavity 402 and an air inlet cavity 403 through a blade cover air duct opening 401.

[0078] The upper fragrance spring fixing member 12 and the lower fragrance spring fixing member 15 are connected by buckles or threads, and after combination, a cylindrical closed cavity is formed for wrapping the fragrance spring 18, and the cylindrical closed cavity is only communicated with the outside through the first fixing member air duct opening 1201, so as to ensure that the fragrance volatilization path is controllable.

[0079] One side of the upper fragrance spring mounting portion is provided with a self-locking switch 13 for locking the blade 6 when the blade 6 rotates to a preset angle. The self-locking switch 13 is forcibly locked after the blade is in place, preventing the blade 6 from being deviated due to air flow impact or vibration. In a preferred example, when the blade 6 rotates to a preset angle, the spring pin or magnetic attraction mechanism of the self-locking switch 13 pops out and is clamped with the groove or protruding structure on the blade 6, forming a mechanical lock, and the blade 6 can be unlocked again only after the motor 14 is reversely driven.

[0080] The motor 14 is a plurality of motors 14 which are installed in sequence; one fragrance spring 18 is installed on each side of the motor 14, the blade cover air duct opening 401 corresponding to the top of the fragrance spring 18 located on one side of the motor 14 is controlled to be turned on and off by a first blade 601, and the blade cover air duct opening 401 corresponding to the top of the fragrance spring 18 located on the other side of the motor 14 is controlled to be turned on and off by a second blade 602. The parallel layout of multiple motors supports the expansion of more fragrance types and meets the needs of complex scenes. Each motor 14 independently controls the air duct on-off of the fragrance spring 18 on both sides, and multiple motors 14 work cooperatively through programmed time sequence control, so as to realize the alternating release or mixed output of multiple fragrances.
