Description

Technical Field

[0001] This utility model relates to the field of fragrance technology, specifically to a car fragrance system. Background Technology

[0002] With the rapid development of the automotive industry and the improvement of people's living standards, cars are no longer just a means of transportation. A comfortable driving and riding environment has become a hot topic for consumers when choosing a car. Therefore, the air environment inside the car has become increasingly important, leading to the rise of car fragrance systems in the automotive industry. Car fragrance systems can purify the air inside the car, remove odors through the emitted fragrance, relieve fatigue, prevent drowsiness while driving, relax the driver, and improve driving safety.

[0003] Existing car fragrance systems, such as the Chinese utility model "fragrance device" with publication number CN 214450160 U, use a single piston rod in the damper assembly that controls the fragrance cartridge's receiving cavity. The piston rod needs to pass through the middle of the receiving cavity, which will interfere with the fragrance cartridge's placement. The fragrance cartridge's unique shape results in a small fragrance capacity, which needs to be improved. Utility Model Content

[0004] One of the technical problems to be solved by this application is to overcome the defects of the above-mentioned related technologies and provide a car fragrance system with a regular shape of fragrance cartridges and a large fragrance capacity.

[0005] The technical solution adopted by this application to solve the technical problem is as follows: an automotive fragrance system, comprising multiple cavities arranged side by side for accommodating different fragrance cartridges, a piston assembly for opening or closing the corresponding cavities, and a drive mechanism for driving the piston assembly. The drive mechanism is installed in a power box. The piston assembly includes a piston body, which is used to simultaneously close the air inlet and outlet of the corresponding cavity in a first position, and to simultaneously open the air inlet and outlet of the corresponding cavity in a second position. The piston assembly further includes a piston rod separately connected to the piston body, the tail end of which passes through the power box and connects to the piston body. The piston body includes an inlet sealing portion for sealing the air inlet when it is in contact with the air inlet of the cavity, and an outlet sealing portion for sealing the air outlet when it is in contact with the air outlet of the cavity. Connecting portions are provided on both sides of the inlet sealing portion and the outlet sealing portion for connection. The fragrance cartridge is housed in the middle of a frame formed by the inlet sealing portion, the outlet sealing portion, and the connecting portions on both sides.

[0006] Compared with related technologies, this utility model has the following advantages: the piston body used to control the fragrance cartridge receiving cavity is modified into a frame formed by an inlet sealing part, an outlet sealing part, and connecting parts on both sides, so that the fragrance cartridge can be placed in the frame. The movement of the piston body, that is, the sliding of the frame, will not interfere with the placement of the fragrance cartridge. The fragrance cartridge has a regular shape and can hold more fragrance. Moreover, the piston rod and the piston body are connected separately, so that the structure of the piston body will not hinder the installation of the piston body and the fragrance cartridge receiving cavity.

[0007] As an improvement, the outer side of the connecting part is provided with a protruding slider, and the cavity walls on both sides of the receiving cavity are provided with sliding grooves, and the sliders slide in cooperation with the sliding grooves. This is used to guide the sliding of the frame in the receiving cavity, and at the same time ensure the stable operation of the piston body in controlling the opening or closing of the air inlet and outlet of the receiving cavity.

[0008] As an improvement, the connecting part includes two horizontal bars arranged vertically, each bar having two sliders; the cavity wall on the same side has two sliding grooves. This provides a more stable guiding and limiting effect.

[0009] As an improvement, limiting protrusions are provided on both sides of the outlet sealing part. These are used to prevent excessive movement of the piston body and to prevent the piston body from separating from the piston rod.

[0010] Preferably, the inner end of the outlet sealing part is provided with two insertion posts, which are respectively inserted and fixed into two insertion holes at the tail end of the piston rod. This makes the assembly operation of the piston body and the piston rod relatively simple. Attached Figure Description
