Description

Technical Field

[0001] The embodiments of the present application relate to a tent and a ventilation system with filtering functions. Background Art

[0002] The acidic components in rainwater have a strong corrosive effect on the paint surface of the car, which will cause damage to the paint surface of the car over time. Therefore, many cars have damaged paint and need to be beautified / repaired.

[0003] There is a great demand for car paint repair, but many painters are unable to paint outdoors due to the weather. Traditional spray booths are very expensive and cannot be moved, resulting in very limited workspace and flexibility. The cheaper inflatable tents have poor performance in terms of waterproofing and windproofing, and can only be used outdoors in sunny weather. If the vehicle is sprayed indoors, a larger indoor area is required with certain ventilation. In addition, the existing tents lack an ideal filtering solution for the gas entering and leaving the tent, resulting in low air quality entering the tent, affecting the quality of beauty / repair; or the gas discharged from the tent is more complex, which is not conducive to environmental protection.

[0104] See also Fig.24 As shown, the ventilation device 60 includes a bellows 601, in which a fan is arranged, a filter box 602 is arranged at the first end of the bellows 601, and a filter element 604 is arranged in the filter box 602. The filter box 602 is connected to the second window 1401 of the tent through a fifth connecting piece and is connected to the interior of the tent. A ventilation port 603 is arranged at the second end of the bellows 601. The material and properties of the filter element 604 can be selected according to the actual needs. Multiple layers of the same or different filter elements 604 can also be selected according to the needs to achieve the corresponding filtering requirements. The filter box can be selectively arranged at the air inlet and / or the air outlet of the bellows.

[0105] The ventilation device 60 has two working modes, which can be selected to supply air into the tent or to extract air from the tent. The corresponding working mode can be selected according to needs.

[0106] The tent can be provided with one or more ventilation devices 60 as required, and each ventilation device 60 can select its own working mode as required, for example:

[0107] Fig.25 In the figure, the ventilation device 67 on the right side supplies air inwards;

[0108] Fig.26 In the figure, the ventilation device 61 on the left side draws air outwards, and the ventilation device 62 on the right side delivers air inwards;

[0109] Fig. 27 In the figure, the ventilation device 63 on the left side supplies air inwards, and the ventilation device 64 on the right side supplies air inwards;

[0110] Fig.28 In the figure, the ventilation device 65 on the left side draws air outwards, and the ventilation device 66 on the right side draws air outwards;

[0111] In each figure, the direction of air flow in the tent can refer to the direction indicated by the arrow in the figure. However, if the air output of the ventilation device 60 at both ends is different, the direction of air flow in the above figure will be changed accordingly.

[0112] The filter element 604 in the ventilation device 60 and the filter cotton 18 at each window can both play a filtering role; when air is taken into the tent, the outdoor air can be filtered; when air is exhausted outside the tent, the indoor gas can be filtered.

[0113] Of course, the number of ventilation devices 60 to be installed can also be selected according to needs, and one of the sides in the above figure can be selected for installation, and the working mode of the ventilation device 60 can be selected according to actual needs. In addition, in some embodiments, the ventilation device 60 can also be installed in the remaining windows.

[0114] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
