[0026] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0027] Basic configuration

[0028] FIG. 1 is a schematic diagram illustrating an air vent device of a vehicle according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view along A-A' shown in FIG. 1.

[0029] Referring to FIGS. 1 and 2, the vehicle's air vent device (100) is mounted inside the dashboard (not shown) of the vehicle and guides air entering from the vehicle's air conditioner (not shown) into the vehicle's interior by switching it to a direct air mode or an indirect air mode.

[0030] The air vent device (100) of the vehicle includes a duct section (110), a vent section (120), and a spray section (130).

[0031] The duct section (110) has an inlet connected to the vehicle's air conditioner, an outlet (outlet side) facing the vehicle interior, and an air passage between the inlet and the outlet.

[0032] A connecting hole (111) is formed at the lower end of the outlet of the duct section (110).

[0033] The vent section (120) controls the airflow direction toward the outlet of the duct section (110). This vent section (120) is equipped with a wing knob (121) so that the user can manually control the airflow direction.

[0034] The wing knob (121) has a structure that links with separate wings that are adjustable left and right and up and down in the vent section (120).

[0035] The wing knob (121) is hinge-connected to the outlet side of the duct section (110) and can be adjusted up and down with respect to the hinge axis. At this time, one end of the wing knob (121) functions as a handle, and the other end of the wing knob (121) can function as a pressure trigger (121a) that presses the pressure member (133) to be described later.

[0036] The spraying unit (130) is positioned at the bottom of the duct unit (110) and sprays antibacterial liquid into the duct unit (110) when pressurized by the pressurizing trigger (121a) of the wing knob (121).

[0037] The injection unit (130) includes a housing (131), a connecting pipe (132), a pressurizing member (133), an elastic member (134), a hose (135), and a hose knob (136).

[0038] The housing (131) is a storage tank containing antibacterial liquid and includes an outer case (131a) and an inner case (131b).

[0039] The outer case (131a) functions as a frame that maintains the overall structure of the housing (131) and is located on the inner side of the garnish (10), communicating with the connecting hole (111) of the duct section (110) through the connecting pipe (132).

[0040] The inner case (131b) is formed with a shape corresponding to the outer case (131a) and has a structure that can be inserted into the inner section of the outer case (131a). The inner case (131b) communicates with the connecting hole (111) of the duct section (110), just like the outer case (131a).

[0041] The connecting pipe (132) connects the connecting hole (111) of the duct section (110) with the housing (131). This connecting pipe (132) is formed with both ends open.

[0042] A cylinder hole (132a) is formed at the lower part of the body of the connecting tube (132) that penetrates the outer case (131a) and the inner case (131b). The cylinder hole (132a) is formed to be smaller than the inner diameter of the connecting tube (132).

[0043] A spray nozzle (132b) is provided on the side of the body of the connecting pipe (132) to form a channel that is partially penetrated so that the antibacterial liquid can be sprayed into the interior of the duct (110).

[0044] The pressure member (133) can move up and down within the inner diameter of the connecting pipe (132). This pressure member (133) can be pressed downward by the pressure trigger (121a) of the wing knob (121).

[0045] The elastic member (134) is positioned on the inner diameter of the connecting pipe (132) and is placed below the pressure member (133) to provide elastic force toward the pressure member (133).

[0046] The hose (135) is embedded in the housing (131) and has a structure that penetrates the cylinder hole (132a) and communicates with the connecting pipe (132). This hose (135) has an integrated structure in which the inclined section and the vertical section are connected as one, and the lower end of the inclined section contacts the bottom surface of the embedded case (131b).

[0047] The hose knob (136) is connected in a manner that wraps around the outer circumference of the hose (135), preferably connected to the vertical portion of the hose (135). This hose knob (136) serves as a handle to allow the user to adjust the position of the hose (135).

[0048] Operating mechanism of the injection unit (130)

[0049] FIG. 3 is an example diagram of the operation of an air vent device of a vehicle according to one embodiment of the present invention.

[0050] Referring to FIG. 3, when the pressurizing member (133) of the spraying unit (130) is pressurized by the pressurizing trigger (121a) of the wing knob (121), the antibacterial liquid in the internal case (131b) moves upward along the hose (135) according to the Bernoulli principle (theorem).

[0051] The antibacterial liquid moved upward along the hose (135) is sprayed out of the spray nozzle (132b) (inside the duct section (110)) through the connecting pipe (133a) of the pressurizing member (133).

[0052] Since air flows toward the outlet of the duct section (110), the antibacterial liquid sprayed into the duct section (110) by the spray nozzle (132b) can move into the vehicle interior along with the airflow.

[0053] Accordingly, the air vent device (100) of the vehicle has a structural feature that allows the user to simply adjust the wing knob (121) upward to spray antibacterial liquid into the vehicle interior.

[0054] The spraying unit (130) may selectively spray antibacterial liquid through a driving unit (not shown) that rotates the wing knob (121) to a preset angle.

[0055] Detachable structure of the injection part (130); left and right detachable method

[0056] FIGS. 4 to 6 are exemplary diagrams illustrating the detachable structure of the injection part in an air vent device of a vehicle according to one embodiment of the present invention.

[0057] Referring to FIGS. 4 to 6, the inner case (131b) can be optionally detached from the outer case (131a). For example, the detachment structure of the inner case (131b) and the outer case (131a) can be formed by sliding in the front-rear direction.

[0058] First, when the inner case (131b) is removed from the outer case (131a), the hose (135) must descend through the hose knob (136) so as not to come into contact with the connecting pipe (132). Additionally, the vertical movement path of the hose knob (136) must be ensured through a separate slit, and the length of the slit must be such that the minimum hose (135) can be mounted on or removed from the connecting pipe (132).

[0059] When the hose (135) is moved downward by the hose knob (136) and the lower end of the hose (135) touches the inner bottom surface of the inner case (131b), it is preferable that the upper end of the hose (135) does not protrude to the upper surface of the inner case (131b). This is because the sliding detachable structure of the inner case (131b) is possible only when the hose (135) is embedded in the inner case (131b).

[0060] In the section where the inner case (131b) and the outer case (131a) come into contact, a separate caster or rail may be provided to assist in sliding operation.

[0061] Meanwhile, when the inner case (131b) is mounted on the outer case (131a), the inner case (131b) must be in close contact with the interior of the outer case (131a). At this time, a snap-fit ​​fastening structure that facilitates easy mounting or removal operations between the inner case (131b) and the outer case (131a) may be adopted.

[0062] Next, when the inner case (131b) is in close contact with the outer case (131a), the hose (135) can communicate with the connecting pipe (132) through the cylinder hole (132a) by adjusting the hose knob (136) upward. Here, the hose knob (136) can fix its current position through a separate stopper (not shown).

[0064] FIGS. 7 and 8 are exemplary diagrams illustrating the detachable structure of the injection part in an air vent device of a vehicle according to another embodiment of the present invention.

[0065] Referring to FIGS. 7 and 8, the air vent device (100') of a vehicle according to another embodiment of the present invention has a different shape of the injection part (130') compared to the previously described embodiment. Therefore, the description of the same configuration already described above will be omitted, and the differences will be examined in detail.

[0066] The injection unit (130') illustrated in FIGS. 7 and 8 has a structure in which the inner case (131b') is detached from the outer case (131a') in the up and down direction.

[0067] This embodiment relates to a structure that can conceal the location for replacing the antibacterial liquid inside a vehicle, wherein, basically, the spraying part (130') can be embedded inside the garnish, with the remaining portion excluding the lower portion. This form is significant in that it can increase design freedom and quality.

[0068] Basically, the bottom part of the outer case (131a') is formed in an open shape.

[0069] The internal case (131b') is formed in a shape corresponding to the external case (131a') and is embedded in the external case (131a') through the lower part of the external case (131a').

[0070] At this time, a snap-fit ​​fastening structure that facilitates easy mounting or removal operations between the inner case (131b') and the outer case (131a') may be adopted.

[0071] Additionally, a separate bracket (not shown) capable of effectively supporting the inner case (131b') may be provided on the lower perimeter of the outer case (131a').

[0072] The present invention is not limited to the aforementioned embodiments and may be implemented with various modifications within the scope permissible to the technical concept of the present invention. Explanation of the symbols
