[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The utility model aims to provide a ventilation pipe and a ventilation system to solve the problems existing in the prior art, so that the focus point of stretching the ventilation pipe is clear and the installation and disassembly of the air supply device are convenient.

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Embodiment 1:

[0035] like Figure 1-Figure 5As shown, the utility model provides a ventilation duct 101, including a ventilation duct main body, an air inlet 2 of the ventilation duct main body is used to connect with an air supply device, and a force device is arranged on the side of the air inlet 2 of the ventilation duct main body, the force device is used to provide a force point for the staff to stretch the ventilation duct main body and connect it with the air supply device, the force device provides a force point when stretching the ventilation duct, the operator applies force more clearly during operation, and the operation is more convenient and labor-saving even in a relatively narrow space, so that the installation and disassembly of the air supply device and the ventilation duct 101 are convenient, the force device is preferably a hanging ear 1, and it should be noted that it can also be other devices, as long as it is convenient for the operator to find the force point, for example, it can also be a hand-pull column.

[0036] In this embodiment, the ventilation duct 101 also includes a delivery pipe. The end of the ventilation duct body away from the air supply device is connected to the delivery pipe to provide a circulation channel for the gas blown out by the air supply device. The delivery pipe is preferably a bellows 3. The bellows 3 makes the gas circulation more stable and can avoid the bending of the ventilation duct, so that the wind blown out by the air supply device cannot be fully transmitted to the seat, causing a large amount of air volume loss, making it impossible for the driver to feel enough air volume and unable to provide better comfort requirements. It should be noted that the delivery pipe can also be selected as an ordinary pipe as long as gas circulation can be achieved.

[0037] In the present embodiment, a fixing portion 7 is further provided at one end of the conveying duct away from the air supply device. The fixing portion 7 is used to be fixedly connected to the ventilation bag 103. The ventilation bag 103 is provided with ventilation holes to direct the wind to the seat. The size of the fixing portion 7 is similar to that of the ventilation bag 103 to facilitate the installation of the ventilation bag 103. The fixing portion 7 is preferably a planar structure. It should be noted that other structures may be adaptively selected according to the shape of the ventilation bag 103, such as a curved surface structure with a certain curvature on the surface.

[0038] In this embodiment, the ventilation pipe 101 also includes a positioning device, which is arranged on the fixing portion 7. The positioning device is used to provide a positioning point for the installation of the ventilation bag 103. The positioning device is preferably a positioning column 4 and preferably two of them. The positioning column 4 passes through the positioning hole of the ventilation felt on the ventilation bag 103. The fixing portion 7 and the ventilation felt on the ventilation bag 103 are sewn together by thread. The positioning column 4 can prevent the seaming position of the ventilation pipe 101 and the ventilation bag 103 from changing, and avoid displacement of the installation position. It should be noted that the positioning device can also adopt other types of devices, and the number can also be other quantities, as long as it can play a role in auxiliary positioning, for example, snap-on fasteners.

[0039] Embodiment 2:

[0040] like Figure 6-Figure 8As shown, the utility model also provides a ventilation system, which includes a ventilation bag 103, an air supply device and the ventilation pipe 101 as described above, wherein the ventilation bag 103 is used to be installed on the seat foam, the air outlet of the air supply device is connected to the air inlet 2 of the ventilation pipe 101, the ventilation bag 103 is connected to the air outlet 5 of the ventilation pipe 101, and a plurality of ventilation holes are arranged on the ventilation bag 103, and the plurality of ventilation holes can correspond one by one to the air holes on the seat foam. The air blown out by the air supply device enters the ventilation bag 103 through the ventilation pipe 101, the ventilation bag 103 is adhered to the seat foam, and the ventilation holes on the ventilation bag 103 are connected to the air holes on the seat foam, thereby transmitting the wind to the seat, so that the driver can feel the wind and meet his comfort requirements.

[0041] In this embodiment, the inner surface of the air inlet 2 of the ventilation pipe 101 has a card slot 6, and the outer surface of the air outlet of the air supply device has a card ring. The card slot 6 is used to snap the card ring to lock the air supply device to the air inlet 2 of the ventilation pipe 101. The card slot 6 can clamp the flange of the air supply device to prevent the air supply device from shaking therein, thereby avoiding air volume loss.

[0042] Among them, the air supply device is preferably a centrifugal fan. It should be noted that it can also be other types of air supply devices as long as it can achieve air supply, such as a mixed flow fan.

[0043] In this embodiment, the ventilation bag 103 structure is preferably composed of five layers connected in sequence, namely, double-sided tape, PU film, three-dimensional woven mesh, PU film, and ventilation felt. The double-sided tape part is adhered to the seat foam, and the outermost PU film and ventilation felt are sewn to the ventilation pipe. Its main function is to transfer the wind from the air supply device to the foam so that the driver can feel the wind, thereby meeting the comfort requirements. It should be noted that the ventilation bag structure can also be made of other materials as long as the seat ventilation can be achieved.

[0044] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
