Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ventilation, in particular to a ventilation device and a seat. BACKGROUND

[0002] In recent years, with the continuous development of the automobile industry, users have increasingly high requirements for ride comfort experience, which has also promoted the technological progress of the downstream automobile seat market. In the huge domestic and global market, how to stably and efficiently place the fan module in the seat system is one of the key points that the related supporting manufacturers in the automobile industry chain need to further improve.

[0003] In the traditional way, the seat manufacturer usually connects the fan with the support framework in the seat through a long air guide pipeline, which on the one hand leads to a long air guide channel and large air resistance, affecting the ventilation effect, and on the other hand, in order to ensure the reliability of the connection, the pipeline end and the fan are usually fixedly connected, which makes the fan difficult to be separately disassembled and maintained.

[0004] In view of the above problems, there are corresponding improvements in the prior art, such as the Chinese patent application with publication date of 2018-09-18 and publication number CN108544995A, which discloses an automobile seat ventilation system, comprising a seat foam and a support framework, further comprising: a fan fixed on the support framework and located away from the seat foam; a ventilation bag arranged in the mounting groove of the seat foam; an air duct connecting piece passing through the support framework and communicating with the ventilation bag at one end and the fan at the other end. The automobile seat ventilation system directly sets the fan on the back of the support framework, and realizes the communication between the fan and the ventilation bag through the air duct connecting piece, thereby saving the traditional bulky air guide channel, reducing the installation space requirement, and reducing the air resistance. The shortcomings of this scheme are: the support framework usually includes a mesh structure intersecting horizontally and vertically, which requires the adaptation of the gap size of the air duct connecting piece and the support framework, resulting in poor universality, at the same time, the fan is close to the support framework at the connection between the fan and the air duct connecting piece, which makes the installation of the fan inconvenient, and the air duct connecting piece is easy to be damaged.

Meanwhile, the fan and the flexible telescopic pipe are detachably connected, so that the fan can be individually detached for maintenance, the maintenance cost is controlled, and when the fan and the flexible telescopic pipe are detached, the flexible telescopic pipe can be stretched to make the connection position of the fan and the flexible telescopic pipe away from the mounting member, so that the fan and the flexible telescopic pipe are convenient to be detached. In addition, the fan is also detachably connected with the support framework of the mounting member, such as a seat, a bed and the like, so that the stability and reliability of the fan can be ensured, and when the relative positions of the ventilation structure and the fan are deviated, for example, when the device is arranged on a seat, the position of the ventilation structure is deviated due to the deformation of the seat cushion, the flexible telescopic pipe connecting the ventilation structure and the fan can be deformed and telescoped to offset the deviation, so that the flexible telescopic pipe is not easy to be damaged, and stable and reliable connection between the ventilation structure and the fan can be ensured, that is, the sealing property of the ventilation channel is ensured, so that the ventilation effect is ensured.

[0012] In some embodiments, the other end of the flexible telescopic pipe is connected with a mounting cover, and the mounting cover is detachably connected with the air inlet of the fan.

[0013] By using the above technical scheme, the flexible telescopic pipe is detachably connected with the fan through the mounting cover, so that the flexible telescopic pipe is convenient to be manufactured, and when the mounting cover is damaged, the mounting cover can be replaced for maintenance, so that the device is further convenient to be maintained.

[0039] Embodiment 1:

[0040] Please refer to Figures 1-3 , Figure 1 is a schematic view of the assembly structure of the ventilation device and the seat 1 in the present application; Figure 2 is Figure 1 an exploded schematic view; Figure 3 is a schematic view of the structure of the flexible expansion pipe 3 in the present application.

[0041] The embodiment of the present application provides a ventilation device, which comprises a ventilation structure 2, a flexible expansion pipe 3 and a fan 5. The ventilation device can be installed on any article requiring ventilation, such as a seat, a bed and the like.

[0042] The opposite sides of the ventilation structure 2 are respectively provided with a plurality of ventilation holes 21 and a ventilation port which are in communication with each other, so as to realize ventilation.

[0043] When the device is installed on the seat 1, the ventilation structure 2 is arranged in the seat 1, i.e. arranged in the seat cushion 12. The ventilation structure 2 can be formed by grooving and opening on the seat cushion 12, or can be a separate ventilation air bag. The ventilation structure 2 is provided with a plurality of ventilation holes 21 on the side facing the seat 1 and the human body, and is provided with a ventilation port in communication with the plurality of ventilation holes 21 on the side away from the seat 1 and the human body.

[0044] One end of the flexible telescopic pipe 3 is connected with the air vent of the air ventilation structure 2, and the flexible telescopic pipe 3 can pass through the support framework 11 of the seat 1 by deformation and telescopic extension, so that the other end of the flexible telescopic pipe 3 is detachably connected with the air outlet of the fan 5. The flexible telescopic pipe 3 can be deformed and telescopic extended to adapt to different sizes of the support framework 11 of the seat 1, thereby improving the versatility of the device. In addition, the fan 5 is detachably connected with the flexible telescopic pipe 3, so that the fan 5 can be easily removed for maintenance, thereby reducing the maintenance cost.

[0045] The fan 5 is detachably connected with the support framework 11 of the seat 1, and the air outlet of the fan 5 is close to the support framework 11. The fan 5 is connected with the support framework 11 of the seat 1, so that the stability and reliability of the fan 5 are ensured, and the flexible telescopic pipe 3 does not bear the weight of the fan 5, thereby prolonging the service life of the flexible telescopic pipe 3. Preferably, the fan 5 is connected with a back plate 52, and the back plate 52 extends a plurality of connecting wings. The fan 5 is connected with the support framework 11 through the connecting wings at different positions, thereby further improving the flexibility and convenience of the connection between the fan 5 and the support framework 11.

[0046] It should be noted that the conventional air pipe is a hard pipe. If the relative positions of the air ventilation structure 2 and the fan 5 are offset due to the deformation of the seat cushion 12 during long-term use, the air pipe or the connection between the air pipe and the air ventilation structure 2 and the fan 5 is easily broken, thereby causing air leakage and affecting the air ventilation effect.

[0047] However, in the device, when the relative positions of the air ventilation structure 2 and the fan 5 are offset due to the deformation of the seat cushion 12, the flexible telescopic pipe 3 connected with the air ventilation structure 2 and the fan 5 can be deformed and telescopic extended to offset the misalignment, thereby avoiding damage and preventing the connection between the flexible telescopic pipe 3 and the air ventilation structure 2 and the fan 5 from being broken. The stable and reliable connection between the air ventilation structure 2 and the fan 5 is ensured, that is, the sealing of the air ventilation channel is ensured, thereby ensuring the air ventilation effect. Preferably, the flexible telescopic pipe 3 has a certain elasticity and can restore to the original state.

[0048] In one embodiment, the length of the flexible telescopic pipe 3 is adapted to the thickness of the installation part, so that the fan 5 is away from the installation part when the flexible telescopic pipe 3 is extended, and the fan 5 is close to the installation part when the flexible telescopic pipe 3 is shortened. That is, when the fan 5 is disassembled, the flexible telescopic pipe 3 is stretched to move the connection away from the installation part, so that a larger installation space is obtained, thereby facilitating the disassembly of the end of the flexible telescopic pipe 3 and the fan 5, and improving the installation convenience of the device.

[0049] In one specific embodiment, the flexible telescopic pipe 3 is a telescopic hose, such as a plastic telescopic hose.

[0050] In one embodiment, the other end of the flexible telescopic pipe 3 is connected with a mounting cover 4, and the mounting cover 4 is detachably connected with the air inlet of the fan 5, which facilitates the manufacturing of the flexible telescopic pipe 3, and when the connection is damaged, the mounting cover 4 can be replaced for maintenance, further facilitating the maintenance of the device.

[0051] Please see Figures 4-6 , Figure 4 The structure diagram of the mounting cover 4 in the present application is shown in the figure. Figure 5 The structure diagram of the fan 5 in the present application is shown in the figure. Figure 6 The assembly structure diagram of the fan 5 and the mounting cover 4 in the present application is shown in the figure, wherein the clamping hooks 51 are located in the avoiding grooves 441.

[0052] In one embodiment, the air inlet of the fan 5 is connected with the other end of the flexible telescopic pipe 3, that is, the device is a suction system. Preferably, the fan 5 adopts a vortex fan.

[0053] In one embodiment, a plurality of clamping hooks 51 are uniformly arranged around the circumference of the air inlet of the fan 5.

[0054] The mounting cover 4 is provided with a groove 44 matched with the plurality of clamping hooks 51, and the plurality of clamping hooks 51 can enter and exit the groove 44 and rotate in the groove 44 to switch between the locked state and the unlocked state.

[0055] This way, through the plurality of clamping hooks 51 uniformly arranged around the circumference and the matched groove 44, the fan 5 can still be connected with the mounting cover 4 after rotating at a proper angle, further improving the flexibility of the fan 5 installation, and facilitating the arrangement of the fan 5 air outlet and wiring.

[0056] Preferably, the clamping hooks 51 are provided with four, and the fan 5 can be installed at 0° or 180° position.

[0057] In one specific embodiment, the groove 44 has an avoiding groove 441 and a step portion 442, the plurality of clamping hooks 51 enter and exit the groove 44 through the avoiding groove 441 and are located in the unlocked state, and the plurality of clamping hooks 51 can be rotated from the avoiding groove 441 to the step portion 442 and located in the locked state.

[0058] In one embodiment, the mounting cover 4 includes a first annular support 41 and a second annular support 42 coaxially and spaced apart, and the first annular support 41 and the second annular support 42 are connected through a plurality of connecting rods 43 arranged in the circumferential direction; and the diameter of the first annular support 41 is smaller than the diameter of the second annular support 42, the first annular support 41 extends into the flexible telescopic pipe 3 and is connected therewith, and the second annular support 42 is provided with the groove 44.

[0059] The mode makes the installation cover 4 as a whole in the shape of a frustum skeleton, and extends into the flexible telescopic pipe 3. By supporting the flexible telescopic pipe 3 near the air outlet of the fan 5 through the installation cover 4, it can ensure that the part which is stretched and contracted repeatedly during the disassembly and assembly process maintains the basic shape, avoids blocking the air outlet, and ensures the ventilation volume. At the same time, the front end of the installation cover 4 is small, which is convenient for embedding the mounting part, such as the seat 1 support skeleton.

[0060] In one embodiment, the two ends of the flexible telescopic pipe 3 are sealingly connected with the ventilation structure 2 and the installation cover 4, which ensures the sealing of the ventilation channel.

[0061] Embodiment 2:

[0062] The embodiment of the present application also provides a seat 1, which comprises a support skeleton 11, a seat cushion 12 sleeved on the support skeleton 11, and the ventilation device of embodiment 1.
