Description

Technical Field

[0001] This invention relates to the field of automotive fragrance components, specifically to a press-type automotive fragrance generator, an automotive fragrance system, and a vehicle. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] With economic development and increasing demands for automotive comfort, in-car fragrance generators, especially in new energy vehicles, have become a standard feature in modern vehicles. Currently, existing fragrance generators typically consist of a generator housing, a brushless blower, a stepper motor, and fragrance cartridges. The fragrance cartridges are fixed within specific fragrance cartridge channels, generating a corresponding fragrance gas. The stepper motor drives the brushless blower located within these channels, forcibly convecting the fragrance gas and filling the car interior with the scent of that particular fragrance.

[0004] Currently, the fragrance cartridges in existing car fragrance generators are mainly fixed by magnetic or clip-on methods. On the one hand, the space is easily limited when fixing the fragrance cartridges. On the other hand, the fragrance cartridges protrude to the outside, which is not aesthetically pleasing and may not even meet the regulatory requirements for protruding objects in automobiles. Moreover, when the fragrance cartridges are frequently replaced, the clip-on fixing method is extremely inconvenient and cumbersome. Summary of the Invention

[0005] To address the aforementioned problems and deficiencies in existing technologies, this invention provides a press-type car fragrance generator, a car fragrance system, and a vehicle. A press-type fragrance cartridge installation device is designed inside the vehicle. This device incorporates a fragrance cartridge labyrinth lock, which securely locks the fragrance cartridge, ensuring stable installation within the fragrance generator, saving space and creating an aesthetically pleasing layout. It also allows for quick and frequent cartridge replacement via pressing, facilitating rapid and frequent changes. Furthermore, the pressing, locking, and ejection of the fragrance cartridges all occur at the bottom, allowing for unrestricted design and freedom in styling. Additionally, this device can simultaneously accommodate multiple fragrance cartridges of different scents, allowing users to select the desired fragrance based on their needs, avoiding the time-consuming process of frequently changing single-scented fragrances and improving the convenience of using the car fragrance system.

[0006] In a first aspect, the present invention provides a press-type car fragrance generator.

[0007] A press-type car fragrance generator includes a fragrance generator housing, wherein the fragrance generator housing is provided with a fragrance component, a fragrance selection component and a fan component;

[0008] The fragrance component includes a fragrance cartridge mounting housing, a fragrance cartridge maze lock, and a fragrance cartridge. The fragrance cartridge mounting housing has multiple fragrance cartridge mounting channels inside, with a fragrance cartridge mounting port and a fragrance cartridge extension port at each end.

The inlet and outlet of each fragrance flow channel correspond to the two vent holes, respectively.

[0010] In a further technical solution, the blower assembly includes a fragrance-emitting brushless blower, which is disposed at the top inside the fragrance generator housing;

[0011] The top of the fragrance generator housing has an air inlet and an air outlet that are not directly connected to each other, and the location of the fragrance-emitting brushless blower is connected to the air outlet located on the top of the fragrance generator housing.

[0012] In a further technical solution, the incense selection barrel is provided with an incense inlet and an incense outlet at both ends, and the barrel wall is provided with a first vent and a second vent. The incense inlet of the incense selection barrel is connected to the first vent, and the incense outlet of the incense selection barrel is connected to the second vent. The incense selection barrel is provided with a partition, which separates the communication channel between the incense inlet and the first vent and the communication channel between the incense outlet and the second vent.

[0013] In a further technical solution, the fragrance inlet of the fragrance selection barrel is connected to the air inlet provided at the top of the fragrance generator housing, and the fragrance outlet of the fragrance selection barrel is connected to the location of the fragrance-discharging brushless blower.

[0014] In a further technical solution, the bottom of the fragrance generator housing is provided with multiple fragrance cartridge insertion ports, and each fragrance cartridge installation port corresponds one-to-one with each fragrance cartridge insertion port.

[0015] A further technical solution is that the fragrance-filled maze lock includes a maze lock body, a maze lock base, a spring, and symmetrical loop locks;

[0016] The maze lock base is fixedly installed inside the fragrance generator housing. The maze lock base is a rectangular shell structure with one open side. The maze lock body, spring, and symmetrical loop locks are all located inside the maze lock base. One end of the spring is fixedly connected to the bottom of the maze lock base, and the other end of the spring is fixedly connected to the maze lock body. The end of the maze lock body connected to the spring has symmetrical maze track grooves on both sides, and the symmetrical maze track grooves match the symmetrical loop locks one by one.

[0017] In a further technical solution, the loop lock has a ring structure, with one end fixed to the base of the maze lock and the other end movably fitted into the maze track groove; the maze track groove is provided with a locking point and a pop-out point.

[0018] In a further technical solution, the other end of the maze lock body that is not connected to the spring has symmetrically movable connecting claws on both sides of the top.

[0019] The latch has an open / released state and a closed / locked state. When the fragrance cartridge is in the pop-out state, the latch is not subject to external force and is in the open / released state. When the fragrance cartridge is in the locked state, the latch is squeezed by the two side walls of the maze lock base and gets stuck in the groove at the top of the fragrance cartridge and is in the closed / locked state.

[0020] Secondly, the present invention also provides a vehicle fragrance system.

[0021] A vehicle fragrance system includes the push-button vehicle fragrance generator, an external controller, and a touch display screen as described in the first aspect;

[0038] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0039] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0040] Example 1

[0041] like Figure 1 As shown, this embodiment discloses a press-type car fragrance generator, including a fragrance generator housing 2, which is a rectangular housing. The top of the housing has an air inlet 3 and an air outlet 1, and the bottom of the housing has multiple fragrance cartridge insertion slots. In this embodiment, three fragrance cartridge insertion slots are provided for inserting and placing fragrance cartridges 4. In addition, the housing contains a fragrance component, a fragrance selection component, and a fan component. Furthermore, the fragrance generator housing 2 is divided into an upper housing 21 and a lower housing 22, which are matched with each other to facilitate the installation of the above components in the housing. An air outlet sponge 11 is provided at the air outlet to filter impurities in the blown airflow.

[0042] The fragrance component is located at the bottom inside the casing, such as... Figure 2As shown, the fragrance assembly includes a fragrance cartridge mounting housing 9, a fragrance cartridge maze lock 8, and a fragrance cartridge 4. The fragrance cartridge mounting housing 9 has multiple fragrance cartridge mounting channels inside. One end of each fragrance cartridge mounting channel is a fragrance cartridge mounting port, and each fragrance cartridge mounting port corresponds to a fragrance cartridge insertion port. The other end of the fragrance cartridge mounting channel is a fragrance cartridge extension port. A fragrance cartridge maze lock 8 is fixedly installed at the fragrance cartridge extension port. The fragrance cartridge maze lock 8 has a claw 831, which matches the groove on the top of the fragrance cartridge extending out of the fragrance cartridge outlet, thereby locking the fragrance cartridge in place.

[0043] like Figure 3 As shown, the fragrance maze lock 8 includes a maze lock body 83, a maze lock base 81, a spring 82, and symmetrical loop locks 84. The maze lock base 81 is fixedly installed inside the fragrance generator housing 2. The maze lock base 81 is a cuboid housing structure with one open side. The maze lock body 83, spring 82, and symmetrical loop locks 84 are all located inside the maze lock base 81. One end of the spring 82 is fixedly connected to the bottom of the maze lock base 81, and the other end of the spring 82 is fixedly connected to the maze lock body 83. Figure 4 The diagram in (a) shows the fragrance-activated maze lock in the activated fragrance state. The maze lock body 83 is connected to the spring 82 at one end, and symmetrical maze track grooves 832 are provided on both sides. These symmetrically arranged maze track grooves 832 are matched one-to-one with symmetrical loop locks 84. Specifically, the loop lock 84 has a ring structure. One end of the loop lock 84 is fixed to the maze lock base 81, and the other end of the loop lock 84 is movably fitted into the maze track groove 832, allowing it to move within the groove. Figure 4 The diagram shown in (b) illustrates the state of the fragrance pod locked by the maze lock. The maze track groove 832 has a locking point 8322 and an ejection point 8321. The loop lock can be stuck at the locking point to achieve fixation. Similarly, the loop lock can be stuck at the ejection point to prevent the loop lock from leaving the maze track groove.

[0044] As another implementation method, such as Figure 5 As shown, a fixing rod is fixedly installed at the bottom of the maze lock base 81, and a spring 82 is sleeved on the fixing rod. The maze lock body 83 has a groove matching the fixing rod, and the fixing rod with the spring 82 can extend into the groove within the maze lock body 83. The depth of the groove is greater than the length of the fixing rod. One end of the spring 82 is fixedly connected to the bottom of the maze lock base 81, and the other end of the spring 82 is fixedly connected to the maze lock body 83. By setting the fixing rod as described above, the problem of displacement of the maze lock body 83 during spring compression and extension can be avoided.

[0045] Furthermore, at the other end of the maze lock body 83 that is not connected to the spring 82, there are symmetrically arranged claws 831 on both sides of its top. The claws 831 are movably connected to the maze lock body 83 and have two states: an open and released state and a closed and locked state. When the fragrance cartridge is in the popped-out state, the claws are not subject to external force and are in the open and released state. When the fragrance cartridge is in the locked state, the claws are squeezed by the two side walls of the maze lock base and are locked into the groove at the top of the fragrance cartridge and are in the closed and locked state.

[0046] The fragrance pod's maze lock structure allows for both pressing and ejection. Specifically, as shown... Figure 5 The diagram in (a) shows the installation of the fragrance cartridge in the maze lock. When no fragrance cartridge is installed, the spring 82 inside the fragrance cartridge maze lock 8 is in a naturally extended state, and the loop lock 84 is located at the ejection point. At this time, the claw 831 on the maze lock body 83 is located outside the maze lock base 81. The claw is in an open and released state. At this time, the claw does not contact the groove at the top of the fragrance cartridge. At this time, the fragrance cartridge can be taken out and inserted.

[0047] like Figure 5 The diagram in (b) illustrates the installation of a fragrance-activated maze lock. When installing the fragrance-activated pod, insert it through the installation port. The top of the pod contacts and presses against the maze lock body, compressing the spring and allowing the maze lock body to further enter the base. As the pod is pressed in, the claws on both sides of the maze lock body move under the pressure of the side walls of the base, engaging the groove at the top of the pod until it locks in place. Simultaneously, the loop lock moves through the maze track groove to the locking point and engages, thus securing the maze lock body. After this securing action, the fragrance-activated pod is fully inserted, with its end flush with the installation port on the housing. Furthermore, the symmetrical arrangement of the loop lock and maze track groove ensures the balance of the maze lock body's movement, preventing tilting and jamming.

[0048] When removing the fragrance cartridge, press the end of the inserted fragrance cartridge to compress the spring again. The fragrance cartridge is pushed out by the spring force. During the pushing process, the loop lock moves in the maze track groove to the ejection point position, no longer fixing the maze lock body. At this time, the spring extends, and the maze lock body moves along the fragrance cartridge axis under the action of the spring force. The claws on both sides of the maze lock body move to break away from the restriction of the two side walls of the maze lock base. The claws become open and released, no longer holding the groove on the top of the fragrance cartridge. The fragrance cartridge is in a free state, and under the push of the spring, the end (i.e., the head) of the fragrance cartridge protrudes from the fragrance cartridge installation port of the fragrance cartridge installation shell, making it easy to remove the fragrance cartridge for replacement, etc.

[0049] The fragrance selection component includes a fragrance selection stepper motor 6, a fragrance selection barrel 7, and a multi-channel fragrance flow structure 10, such as... Figure 6 The left and right side views of the fragrance selection barrel shown in (a) and (b) indicate that the fragrance selection barrel 7 is a hollow cylindrical structure. The two ends of the fragrance selection barrel 7 are respectively provided with a fragrance inlet 74 and a fragrance outlet 75. The barrel wall of the fragrance selection barrel 7 has two ventilation holes, namely a first ventilation hole 71 and a second ventilation hole 72. A partition is provided between the two ventilation holes to separate them from each other, meaning that the fragrance selection barrel has an internal partition that separates the communication channel between the fragrance inlet and the first ventilation hole and the communication channel between the fragrance outlet and the second ventilation hole. Specifically, the fragrance inlet of the fragrance selection barrel is connected to the first ventilation hole, and the fragrance outlet of the fragrance selection barrel is connected to the second ventilation hole. The fragrance inlet of the fragrance selection barrel is connected to the air inlet located at the top of the fragrance generator housing, and the fragrance outlet of the fragrance selection barrel is connected to the location of the brushless blower for fragrance dispensing.

[0050] Furthermore, the aforementioned fan assembly includes a fragrance-emitting brushless blower 5, which is located at the top inside the fragrance generator housing. The top of the fragrance generator housing has an air inlet and an air outlet that are not directly connected to each other. The location of the fragrance-emitting brushless blower is connected to the air outlet located at the top of the fragrance generator housing.

[0051] Additionally, a fixing member 73 is fixedly installed at one end of the fragrance selection barrel with the fragrance inlet hole, and this fixing member 73 is connected to the fragrance selection stepper motor 6. The multi-channel fragrance flow structure 10 includes multiple fragrance flow channels that are not interconnected, including a first fragrance flow channel 101, a second fragrance flow channel 102, and a third fragrance flow channel 103. Each fragrance cartridge installation channel has a fragrance inlet, which is connected to a corresponding fragrance flow channel. Each fragrance flow channel includes a flow inlet and a flow outlet. The flow inlet is aligned with the first vent hole of the fragrance selection barrel, and the flow outlet is aligned with the second vent hole of the fragrance selection barrel. By setting up the multi-channel fragrance flow structure, the fragrance of different fragrance cartridges can be satisfied, while the fragrances of different fragrance cartridges do not mix. When the fragrance generator is not working, the vent hole on the fragrance selection barrel is in a state of being disconnected from the multiple fragrance flow channels.

[0052] Specifically, such as Figure 7 and Figure 8 As shown, when the incense selection stepper motor drives the incense selection barrel to rotate at a certain angle, the two vent holes on the barrel wall are aligned with the outlet and inlet of one of the incense channels (three incense channels in this embodiment). Figure 7 and Figure 8The dotted line in the diagram represents the fragrance path. The air enters through the air inlet on the fragrance generator housing, passes through the fragrance inlet hole into the fragrance selection barrel, and then enters a specific fragrance channel (entering from the channel inlet directly opposite the first vent) through the first vent hole. The air then enters the corresponding fragrance cartridge installation channel, where it mixes with the fragrance essence on the fragrance cartridge to form a specific fragrance gas. This gas is then output from the fragrance channel to the second vent hole on the fragrance selection barrel (flowing out from the second vent hole directly opposite the channel outlet), and exits through the fragrance outlet hole connected to the second vent hole. The fragrance gas is then drawn into the fragrance brushless blower, which blows the fragrance gas out from the air outlet on the fragrance generator housing, thus completing the entire fragrance extraction process.

[0053] The press-type car fragrance generator proposed in this invention has a fragrance cartridge hidden inside the fragrance generator during operation. The end of the fragrance cartridge is flush with the outer surface of the fragrance generator, saving space and improving the overall aesthetics of the vehicle. By setting a fragrance cartridge maze lock, it is easier to replace the fragrance cartridge. The fragrance cartridge maze lock is set at one end of the fragrance cartridge and does not affect the shape design of the fragrance cartridge.

[0054] Example 2

[0055] This embodiment proposes an in-vehicle fragrance system, including a press-type in-vehicle fragrance generator, an external controller, and a touch display screen as described in Embodiment 1.

[0056] In this embodiment, three different fragrance cartridges are provided, each with a different scent. The fragrance cartridge is not fixed in the fragrance cartridge housing and its position can be adjusted arbitrarily. Inside the fragrance cartridge housing of the aforementioned press-type car fragrance generator, each fragrance cartridge installation channel is equipped with an NFC sensor. The fragrance cartridge is equipped with an NFC chip containing fragrance information. The NFC sensor inside the fragrance cartridge housing, combined with the NFC chip containing software information on the fragrance cartridge, can automatically identify the fragrance type of the corresponding fragrance cartridge.

[0057] Furthermore, the fragrance selection stepper motor, the fragrance-dispensing brushless blower, the NFC sensor, and the external controller are electrically connected, and the external controller is electrically connected to the touch screen. The NFC sensor is used to sense the NFC chip and obtain the position and fragrance information of the sensed fragrance cartridge, and transmits the sensed information to the external controller. The external controller transmits the information to the touch screen for display, and the user interacts with the touch screen to select the desired fragrance. The external controller receives the fragrance selection command from the touch screen, controls the fragrance selection stepper motor to run, drives the fragrance selection barrel to rotate to the fragrance flow channel corresponding to the corresponding fragrance, and simultaneously controls the fragrance-dispensing brushless blower to run, so as to generate fragrance.
