[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] refer to Figure 1 , Figure 2 A continuously ventilated inflatable seat cushion includes: a main air chamber 1, a cylindrical strap 2, a ventilation tube 3, and an air pump.

[0032] The main air chamber 1 is an inflatable structure formed by sealing and connecting at least two layers of airtight flexible material, used to provide support and cushioning for the seat cushion. The main air chamber 1 has a first air inlet 11 fixed to the side of the seat cushion.

[0033] Several cylindrical pull straps 2 are distributed along a rectangular array and penetrate the upper and lower surfaces of the main air chamber 1. The two ends of the cylindrical pull straps 2 are respectively connected to the upper and lower layers of airtight flexible material of the main air chamber 1, forming a ventilation channel 21 that runs through the main air chamber 1.

[0034] The ventilation pipe 3 is located inside the main air chamber 1 and is connected to each cylindrical strap 2. The ventilation pipe 3 has a second air inlet 31 fixed to the side of the seat cushion.

[0035] An air pump (not shown) is used to inflate the main air chamber 1 and continuously supply air into the cylindrical pull belt 2.

[0036] The tubular strap 2 serves two purposes: firstly, it limits the thickness and shape of the inflatable seat cushion, and secondly, it provides ventilation channels.

[0037] refer to Figure 4Preferably, the inflatable seat cushion also includes a pressure relief valve 4. The air inlet of the pressure relief valve 4 is connected to an air pump, the air outlet of the pressure relief valve 4 is connected to the inflation port of the main air chamber 1, and the pressure relief port of the pressure relief valve 4 is connected to the second inflation port 31 of the ventilation pipe 3. The pressure relief valve 4 is used to guide the air from the air pump into the ventilation pipe 3 when the air pressure in the main air chamber 1 reaches a preset threshold, and then circulate the air to the skin through the cylindrical strap 2.

[0038] The air pump is a miniature, low-noise DC air pump that can be powered by a rechargeable battery or an external power adapter. It also features multiple speed settings to meet different ventilation needs.

[0039] Preferred, Reference Figure 3 The cylindrical pull strap 2 is cylindrical in shape and is made of a material with a certain elasticity and hardness, so as to keep the inside open when under pressure, such as when a user sits on an inflatable seat. The ventilation pipe 3 is connected to each cylindrical pull strap 2 in sequence along the serpentine direction, so that one ventilation pipe 3 can deliver air to the inside of all the cylindrical pull straps 2.

[0040] Preferred, Reference Figure 4 The air pump is connected to the pressure relief valve 4 through an air supply pipe 5, which allows the air pump to be moved away from the seat cushion, reducing the noise of the air pump during operation.

[0041] Preferably, the two ends of the cylindrical pull belt 2 are provided with fine dustproof mesh covers (not shown) to improve airflow diffusion efficiency and prevent dust or foreign objects from entering the interior of the cylindrical pull belt 2.

[0042] Preferred, Reference Figure 5 The seat cushion is covered with a removable and breathable cover 6 to improve comfort and ease of cleaning.

[0043] Furthermore, refer to Figure 6 The bottom of the outer cover 6 is provided with an anti-slip material layer, such as silicone particles 61 or anti-slip mesh, to increase the friction between the cushion and the seat surface and prevent the cushion from sliding during use.

[0044] On the other hand, the outer cover 6 has straps 62 connected to its side, which are used to secure the seat, thereby further enhancing the stability of the inflatable seat.
