[0036] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] Example 1

[0039] As mentioned in the background technology, in order to solve the problems in the prior art, this application proposes a multi-porous distributed closed ventilation system for car seats, wherein the car seat comprises a foam layer 3, and the foam layer 3 is provided with a plurality of ventilation holes 5 along the thickness direction. Figure 1 Shown, including:

[0040] A ventilation bag 1 having a first cavity therein, wherein a plurality of air distribution holes 4 are provided on the side of the ventilation bag 1 close to the foam layer 3 and connected to the air distribution holes 4 corresponding to the first cavity, and each of the air distribution holes 4 is connected to the first cavity;

[0041] Specifically, the ventilation bag 1 is arranged on one side of the foam layer 3 to ensure that the multiple air distribution holes 4 on the ventilation bag 1 correspond one-to-one to the ventilation holes 5 on the foam layer 3 .

[0042] Specifically, the first cavity is used for air circulation and distribution. The ventilation bag 1 is made of a durable yet flexible material to adapt to the shape of the seat and deformation during use. The shape and size of the ventilation bag 1 are designed based on the size and shape of the car seat and can completely cover the ventilation area on the foam layer 3.

[0043] a ventilation power element 8, which is provided on a side of the ventilation bag 1 away from the foam layer 3 and provides a power source for the air flow in the first cavity;

[0044] Specifically, the ventilation power element 8 can be a small fan or other device that can generate air flow.

[0045] For further information, please refer to Figure 10 As shown, a mounting hole 24 is reserved on the mounting portion 23 of the second sealed air guide component 9 , a rubber rivet 7 is provided in the mounting hole 24 , and the ventilation power element 8 is fixed to the ventilation bag 1 through the rubber rivet 7 .

[0046] The ventilation bag 1 is provided with a closed air guide component at each of the air distribution holes 4. The closed air guide component includes an air guide portion 22 that matches the ventilation hole 5 and is hollow inside, and a mounting portion 23 for fixing. The air guide portion 22 can be embedded in the ventilation hole 5 in a manner that fits tightly with the inner wall surface of the ventilation hole 5 to install the ventilation bag 1 on the foam layer 3. The air guide portion 22 has a first air outlet connected to the interior of the mounting portion 23 on the side away from the mounting portion 23.

[0047] Specifically, when the air guide portion 22 is embedded in the corresponding vent 5, the air distribution hole 4, the vent 5, and the first air outlet are coaxially arranged. The air guide portion 22 and the connecting structure enable the air distribution hole 4, the vent 5, and the first air outlet to be precisely coaxially arranged during installation. This effectively eliminates the problem of the vent 5 not being fully aligned due to tolerances, ensures an unobstructed airflow path, improves ventilation efficiency, and evenly distributes air volume, providing a more comfortable ventilation experience for the user.

[0048] Specifically, the dimensions of the air guide portion 22 of the airtight air guide assembly and the ventilation hole 5 are designed so that the air guide portion 22 can be tightly embedded in the ventilation hole 5. During installation, the air guide portion 22 is inserted into the ventilation hole 5, and the airtight air guide assembly is fixed to the ventilation bag 1 via the mounting portion 23, thereby achieving a tight connection between the ventilation bag 1 and the foam layer 3.

[0049] Specifically, the air guide portion 22 is made of a soft and elastic material, such as rubber or silicone, to ensure a tight fit with the inner wall of the ventilation hole 5 to prevent air leakage. The air guide portion 22 is hollow, forming a passage for air circulation. Air enters the ventilation hole 5 of the foam layer 3 through the first air outlet, thereby ventilating the seat.

[0050] The operating principle of the present application is as follows: when the ventilation power element 8 is working, it draws air into the first cavity of the ventilation bag 1. The air flows in the first cavity and enters the air guide part 22 of the closed air guide assembly through the air distribution hole 4. Since the air guide part 22 fits tightly with the ventilation holes 5 on the foam layer 3, air can only enter the ventilation holes 5 through the first air outlet of the air guide part 22, and then pass through the foam layer 3 to achieve ventilation of the car seat. Through this porous distributed closed ventilation system, uniform ventilation of the car seat can be achieved, improving the comfort and air permeability of the seat. At the same time, the design of the closed air guide assembly can effectively prevent air leakage and improve ventilation efficiency.

[0051] For further information, please refer to Figure 12 and Figure 13 As shown, the porous distributed closed ventilation system of the car seat has a blowing mode and a suction mode, as shown in FIG. Figure 13 As shown, in the blowing mode: the ventilation power element 8 uses a device such as a fan or blower that can generate positive pressure to suck in and pressurize the external air, and then send it into the first cavity of the ventilation bag 1. The air in the first cavity enters the air guide part 22 through the air distribution hole 4. The air is blown out from the first air outlet and passes through the foam layer 3, providing a continuous blowing effect for the car seat, thereby improving the breathability and comfort of the seat. Figure 12 As shown, in the suction mode: the ventilation power element 8 is reversed to generate negative pressure, and the air inside the seat enters the air guide part 22 through the ventilation holes 5 of the foam layer 3 under the action of negative pressure. The air flows from the air guide part 22 into the first cavity and is then sucked out by the ventilation power element 8, thereby replacing the air inside the seat and improving the dryness and comfort of the seat.

[0052] In a preferred embodiment, a connection structure is provided on the outer wall surface of the air guide portion 22 away from the mounting portion 23 , and the air guide portion 22 is interference-connected with the inner wall surface of the ventilation hole 5 through the connection structure.

[0053] Furthermore, the connection structure is an annular inclined platform 26 provided along the radial direction of the air guide portion 22 .

[0054] Furthermore, there are multiple annular inclined platforms, and the multiple annular inclined platforms are stacked along the axial direction of the air guide portion 22 .

[0055] Specifically, the connection structure can be directly connected to the foam layer 3. Alternatively, a snap-fit ​​structure corresponding to the sealed air guide assembly can be provided on the foam layer 3, the snap-fit ​​structure including at least one engaging member for engaging with the connection structure; when the air guide portion 22 is inserted into the corresponding ventilation hole 5, the connection structure is interference-connected with the foam layer 3, and at least one layer of the connection structure is snap-fitted with the engaging member.

[0056] Specifically, the annular ramp 26 can be a layer, such as Figure 5 As shown, a layer of snap-on structure is formed ( Figure 6 middle Figure 6 a is before assembly, Figure 6 b is after assembly), it can also be two layers, such as Figure 7 As shown, a two-layer buckle structure is formed ( Figure 8 ,in Figure 8 a is before assembly, Figure 8 b is after assembly), it can also be three layers, such as Figure 2 and Figure 3 As shown, a three-layer buckle structure is formed ( Figure 4 is an assembly drawing, where Figure 4 a is before assembly, Figure 4 b is after assembly), further, a cross structure is provided in the annular ramp 26, wherein the cross structure is used to reinforce its strength.

[0057] In a preferred embodiment, the enclosed air guide assembly includes a first enclosed air guide assembly 10 and a second enclosed air guide assembly 9;

[0058] The mounting portion 23 of the first sealed air guide component 10 is disposed on a side of the ventilation bag 1 close to the foam layer 3 , and a second air outlet communicating with the first cavity is disposed on the mounting portion 23 of the first sealed air guide component;

[0059] The mounting portion 23 of the second sealed air guiding component 9 is arranged on a side of the ventilation bag 1 away from the foam layer 3 , and the air guiding portion 22 of the second sealed air guiding component 9 is provided with at least one air inlet slot 25 connected to the first cavity.

[0060] It should be noted that the ventilation bag 1 is composed of four layers, so the side of the ventilation bag 1 close to the foam layer 3 can be the two layers of the ventilation bag 1 close to the foam layer 3, and the side of the ventilation bag 1 away from the foam layer 3 can be the two layers of the ventilation bag 1 away from the foam layer 3.

[0061] Specifically, the second enclosed air guide component 9 is provided at a corresponding position of the ventilation power element 8, such as Figure 9 As shown, there are four second closed air guide components 9 at the upper middle position. Except for the corresponding positions of the ventilation power element 8, the other positions are provided with the first closed air guide components 10.

[0062] Specifically, the second air outlet enables air to be discharged from the first cavity through the second air outlet, realizing a specific air flow path, please refer to Figure 3 As shown, the air inlet slot 25 allows external air to enter the first cavity, providing an entrance for air circulation throughout the system. Through this layout, the first enclosed air guide assembly 10 and the second enclosed air guide assembly 9 cooperate with each other to effectively guide and control air circulation, ensuring the normal operation of the entire device and the realization of specific functions.

[0063] Specifically, this arrangement can form an effective air circulation path, where external air enters the first cavity through the air inlet slot 25 of the second sealed air guide component 9, flows within the first cavity, and is then discharged through the second air outlet of the first sealed air guide component 10. This circulation method can ensure that air flows within a specific area (such as the area containing the foam layer 3).

[0064] In a preferred embodiment, the ventilation bag 1 includes a first sealing layer 11, a pressure-bearing air-guiding layer 12, a second sealing layer 13 and a protective layer 14, which are arranged in sequence along the direction of the foam layer 3 pointing to the ventilation bag 1; the mounting portion 23 of the first sealed air-guiding component is fixed on the first sealing layer 11, and the mounting portion 23 of the second sealed air-guiding component 9 is fixed on the second sealing layer 13.

[0065] Specifically, please refer to Figure 11 As shown, the first sealing layer 11, the pressure-bearing and air-guiding layer 12, the second sealing layer 13 and the protective layer 14 can be connected in sequence by means of thermal compression connection or glue bonding.

[0066] Specifically, the first sealing layer 11 prevents air in the first cavity from leaking from the connection with the first sealed air guide assembly, provides a stable fixed position for the mounting portion 23 of the first sealed air guide assembly, and ensures that the first sealed air guide assembly does not move during operation, thereby ensuring that it can normally perform its function of guiding air out of the first cavity. The second sealing layer 13 prevents external air from entering the first cavity without passing through the second sealed air guide assembly 9, provides a fixed base for the mounting portion 23 of the second sealed air guide assembly 9, ensures the stability of the second sealed air guide assembly 9, and enables it to accurately guide external air into the first cavity. The pressure-bearing air guide layer 12 plays a dual role in bearing pressure and guiding air flow in this process.

[0067] In a preferred embodiment, a first air inlet hole 15 is provided on the protective layer 14, a second air inlet hole 16 is provided on the second sealing layer 13, the first cavity is located in the pressure-bearing air-guiding layer 12, and the ventilation power element 8 is connected to the first cavity through the first air inlet hole 15 and the second air inlet hole 16.

[0068] Specifically, the first air inlet hole 15 first allows external air to enter the inner area of ​​the ventilation bag 1 , and then the air further enters the first cavity in the pressure-bearing air-guiding layer 12 through the second air inlet hole 16 on the second sealing layer 13 .

[0069] In a preferred embodiment, a sealing element is provided at the connection portion between the ventilation power element 8 and the ventilation bag 1 .

[0070] Specifically, the sealing element can prevent air from leaking at the connection between the ventilation power element 8 and the ventilation bag 1, ensuring that air can flow along a predetermined path within the ventilation bag 1. Optionally, the sealing element is made of materials such as a rubber sealing ring and a sealant.
