Description

Technical Field

[0001] The utility model relates to an automobile air-conditioning duct, in particular to an automobile air-conditioning duct with a dustproof function, and belongs to the technical field of automobile accessories. Background Art

[0002] The automobile air conditioning duct is an important component of the automobile air conditioning system. It is connected to the outlet of the automobile air conditioning box and mainly plays the role of guiding air, so that the heated or cooled air formed in the automobile air conditioning box is introduced into the cab.

[0003] In the prior art, for example, the utility model with application number 201821300632.X discloses an automobile air-conditioning duct and an automobile air-conditioning system. In order to solve the problems of high noise and poor thermal insulation performance during operation, the air duct is made of soft foam material, the injection molded parts are made of hard plastic, the air duct and the injection molded parts are connected in sequence at intervals, and a support is provided in the end where the air duct and the injection molded parts are connected, and at least some of the injection molded parts have air outlets. The automobile air-conditioning duct has low operating noise and good thermal insulation performance.

[0004] Similar to the above application, there are still some shortcomings:

[0005] During use, dust outside the car can be filtered by the air conditioning filter inside the air conditioning system and will not enter the air conditioning duct. However, dust inside the car can easily enter the air conditioning duct from the front end, causing internal bacteria to grow. When the air conditioning is used again, it will be blown back into the car, affecting the respiratory health of the driver and passengers.

[0006] For this reason, an automobile air conditioning duct with dustproof function is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of the utility model is to provide an automobile air-conditioning duct with a dust-proof function. A partition is rotatably installed at the front end of the air duct body, and the distance between the upper and lower ends of the partition is greater than the height of the air duct body, and a counterweight block is provided at the bottom end of the partition, so that after the air-conditioning system is turned off, the partition can automatically block the air duct body, effectively preventing dust from entering the inside of the air duct body from the inside of the car, and when the air-conditioning system is in use, the partition can be automatically blown open by wind force to release the sealing state, which is more practical. A dehumidification mechanism consisting of a storage box, a desiccant, and a through hole is provided below the front end of the air duct body, so that after the inside of the air duct body is blocked, the inside of the air duct body can be kept dry to prevent bacterial growth.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] The invention discloses an air duct for automobile air conditioning with dustproof function, comprising an air duct body, a rotating shaft being rotatably mounted on one end of the air duct body close to the interior of the vehicle, a partition being fixed on the rotating shaft, the partition being obliquely arranged inside the air duct body, and the partition being fitted with the inner side of the air duct body, a counterweight being arranged at the bottom end of the partition along the length direction, and a dehumidification mechanism being arranged at one end of the air duct body close to the partition.

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides an automobile air-conditioning duct with a dustproof function, including an air duct body 1, a rotating shaft 2 is rotatably installed at one end of the air duct body 1 close to the interior of the vehicle, a partition 3 is fixed on the rotating shaft 2, the partition 3 is obliquely arranged inside the air duct body 1, and the partition 3 is fitted with the inner side of the air duct body 1, a counterweight block 10 is provided at the bottom end of the partition 3 along the length direction, and a dehumidification mechanism 5 is provided at one end of the air duct body 1 close to the partition 3.

[0025] Overall working principle: When in use, first connect the air duct body 1 to the air conditioning system, with one end of the partition 3 facing the air outlet inside the car. When the air conditioning system is not in use, the partition 3 automatically rotates under the action of gravity, and one end of the partition 3 with the counterweight block 10 fits with the bottom of the air duct body 1, forming a barrier to the air duct body 1, effectively preventing dust from entering the interior of the air duct body 1, and utilizing the dehumidification mechanism 5 to ensure that the interior of the air duct body 1 is dry to prevent bacterial growth. When the air conditioning system is in use, the wind discharged by the air conditioning system will blow up the partition 3 to release the blocking state.

[0026] In this embodiment, an upper stopper 4 is fixed to the inner top of the air duct body 1 , and the upper stopper 4 is located at the front end of the partition 3 , and a sealing strip is provided between the upper stopper 4 and the fitting side of the partition 3 .

[0027] Partial working principle: By using the upper stopper 4, it can fit with the top of the partition 3 to increase the contact area and ensure the sealing effect.

[0028] In this embodiment, a lower stopper 6 is fixed to the inner bottom of the air duct body 1 , and the lower stopper 6 is in contact with a side of the partition plate 3 close to the inside of the air duct body 1 .

[0029] Partial working principle: The use of the lower stopper 6 can also increase the contact area with the partition 3 to ensure the sealing effect of the bottom of the partition 3.

[0030] In this embodiment, both upper and lower ends of the partition plate 3 are provided with bends, and the vertical surfaces of the upper and lower ends of the partition plate 3 are respectively fitted between the upper stopper 4 and the lower stopper 6 .

[0031] Partial working principle: The fitting surfaces of the partition 3, the upper stopper 4 and the lower stopper 6 are perpendicular to the horizontal plane, so the fitting effect is better and the sealing is stronger.

[0032] In this embodiment, the dehumidification mechanism 5 includes a storage box 7, a desiccant 8 and a through hole 9. The storage box 7 is fixed at the bottom of the air duct body 1 and is located below the partition 3. The interior of the storage box 7 is filled with desiccant 8, and the top of the desiccant 8 is evenly provided with through holes 9 that are connected to the interior of the air duct body 1.

[0033] Partial working principle: When the air duct body 1 is blocked, the desiccant 8 can absorb the moist gas inside the air duct body 1 to ensure the dryness of the air duct body 1 and avoid bacterial growth.

[0034] In this embodiment, a filling port is provided at the bottom end of the storage box 7, and the desiccant 8 is a silica gel desiccant.

[0035] Partial working principle: Since silica gel desiccant can release moisture in a hot environment, it can be reused.

[0036] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
