DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0023] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0024] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0025] like Figures 1 to 7As shown, an embodiment of the utility model is a vehicle-mounted fragrance generator, comprising a shell 1 and a base 2 connected to the shell 1, and also comprising a driving motor 3, a cam mechanism 4 driven to rotate by the driving motor 3, and at least two fragrances 11, the base 2 is provided with at least two fragrance storage chambers 5 for independently storing the fragrances 11, the base 2 is also provided with a mixing fragrance chamber 6, the fragrance storage chamber 5 is provided with an air duct opening 7 that can be connected to the mixing fragrance chamber 6, and an opening and closing member 8 for opening or closing the air duct opening 7 is movably arranged in the fragrance storage chamber 5, the cam mechanism 4 comprises a driving shaft 9 and a plurality of cams 10 installed on the driving shaft 9, the number of which is equivalent to the number of the fragrance storage chambers 5, and the protrusions of the plurality of cams 10 are in different directions, the cams 10 are cooperatively connected with the corresponding opening and closing members 8, and when the cams 10 rotate, the corresponding opening and closing members 8 move toward or away from the air duct opening 7.

[0026] The beneficial effects of such a setting are as follows: the utility model uses the structural characteristics of the cam mechanism to drive the motor to drive the drive shaft to rotate, and multiple protrusions facing different cams drive the opening and closing parts of the corresponding fragrance storage chambers to move, so that the air duct openings of multiple fragrance storage chambers storing different fragrances can be opened at the same time to achieve mixed fragrance, or only one of the fragrance air duct openings can be opened to achieve separate fragrance, so that the fragrance emitted by the vehicle-mounted fragrance generator has diversity and improves practicality. In addition, a sealing member that is sealed with the opening and closing member is provided at the position corresponding to the air duct opening of each fragrance storage chamber. The opening and closing member is made of elastic material. When the cam drives the opening and closing member away from the air duct opening, the opening and closing member is deformed and separated from the sealing member, and the fragrance of the fragrance storage chamber flows out of the air duct opening from the gap. On the contrary, when the opening and closing member is close to the air duct opening, the opening and closing member is restored and sealed with the sealing member.

[0027] It is further configured that the number of the fragrances 11 is at least three, and the number of the opening and closing parts 8 is also equivalent to the fragrances 11, the opening and closing parts 8 are respectively a first opening and closing part 12, a second opening and closing part 13 and a third opening and closing part 14, the cam mechanism 4 has a first state in which only the first opening and closing part 12 is away from the air duct opening 7, the cam mechanism 4 has a second state in which both the first opening and closing part 12 and the second opening and closing part 13 are away from the air duct opening 7, the cam mechanism 4 has a third state in which only the second opening and closing part 13 is away from the air duct opening 7, the cam mechanism 4 has a fourth state in which both the second opening and closing part 13 and the third opening and closing part 14 are away from the air duct opening 7, and the cam mechanism 4 has a fifth state in which only the third opening and closing part 14 is away from the air duct opening 7.

[0028] The beneficial effects of such a setting are as follows: there are three fragrances with three scents. Driven by the cam mechanism, there is a second state in which the first fragrance and the second fragrance are mixed to produce fragrance, and there is a fourth state in which the second fragrance and the third fragrance are mixed to produce fragrance. In the first, third and fifth states, the first fragrance emits fragrance alone, the second fragrance emits fragrance alone, and the third fragrance emits fragrance alone, respectively. A vehicle-mounted fragrance generator with this structure can emit more scents and the states are easy to switch.

[0029] It is further configured that the opening and closing member 8 is connected to the corresponding cam 10 through a handle 15, and the cam 10 is provided with an annular groove 16 for the handle 15 to extend into. The handle 15 and the annular groove 16 form a matching connection, and the path of the annular groove 16 corresponds to the protrusion direction of the cam 10.

[0030] The beneficial effects of such a configuration are as follows: the opening and closing member is connected to the annular groove of the cam through the handle, and the handle slides along the path of the annular groove when the cam rotates, ensuring that the opening and closing member can be stably driven to move when the cam rotates.

[0031] It is further configured that annular grooves 16 are provided on both sides of the cam 10 , and the annular grooves 16 on both sides of the cam 10 are symmetrically arranged, the handle 15 is a C-shaped structure, and the handle 15 is matched and connected with the annular grooves 16 on both sides of the cam 10 .

[0032] The beneficial effects of this arrangement are as follows: both sides of the cam are recessed with annular grooves for the handle to extend into, and the force is evenly distributed, further ensuring that the cam drives the handle and the opening and closing parts to move flexibly, further ensuring that the air duct opening is opened and closed stably.

[0033] It is further provided that a coupling 17 is connected between the driving motor 3 and the driving shaft 9, and the outer edge of the coupling 17 is recessed with a plurality of grooves 18 along the circumferential direction, and a grating recognition device 19 is provided at a position corresponding to the outer edge of the coupling 17 on the base 2, and the grating recognition device 19 determines the rotation angle of the coupling 17 by detecting the grooves 18. A circuit board is also included, and the grating recognition device is connected to the circuit board.

[0034] The beneficial effects of this arrangement are as follows: when the groove of the rotating shaft rotates into the grating recognition device, the grating recognition device transmits signals to the drive motor and other components through the circuit board, causing the drive motor to stop driving. This is used to determine the angle to which the coupling has rotated, so that the drive motor can control the cam mechanism to stop rotating when it switches to a certain state, and maintain that state to continue to emit fragrance.

[0035] It is further provided that a protrusion 20 is protruded from the outer wall of the coupling 17 , and a first stopper 21 and a second stopper 22 are protruded from the base 2 corresponding to the rotation path of the protrusion 20 .

[0036] The beneficial effects of such a setting are as follows: the protrusion is blocked by the first block and the second block, thereby limiting the rotation of the rotating shaft within a certain angle range; when the protrusion abuts against the first block, the coupling rotates to the minimum angle; when the protrusion abuts against the second block, the coupling rotates to the maximum angle, which facilitates the cam mechanism to switch between multiple states and facilitates the control of the opening and closing of multiple air duct openings.

[0037] Further configuration includes an air outlet component 23 communicated with the fragrance mixing chamber 6 .

[0038] The beneficial effects of such a setting are as follows: the mixed fragrance in the fragrance mixing room is drawn out of the vehicle-mounted fragrance generator through the air outlet component and diffused into the interior of the car, with higher fragrance output efficiency, so that people in the car can smell the fragrance quickly.

[0039] like Figure 8 As shown, the rotating shaft is a coupling, the rotating shaft angle is the angle of rotation of the coupling, air duct 1 is the air duct opening of the first fragrance, air duct 2 is the air duct opening of the second fragrance, and air duct 3 is the air duct opening of the third fragrance. No. 1 is the first fragrance, No. 2 is the second fragrance, and No. 3 is the third fragrance.

[0040] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
