Illustratively, corresponding connectors, such as velcro, magnetic fasteners, straps, etc., may be provided on the inside of the opening of the sidewall of the upper end cap 310 and the outside of the opening of the sidewall of the lower end cap 320 for connecting and securing the upper end cap 310 and the lower end cap 320 to achieve detachable connection and securement between the upper end cap 310 and the lower end cap 320, facilitating detachment and post-maintenance of the components inside the wrapping layer 3, and cleaning maintenance and replacement of the elastic support layer 1 and the air flow circulation layer 2.

Illustratively, the first support structure 110 and the second support structure 210 may be disposed directly inside the wrapping layer 3, and detachably connected therebetween, for example, fixed by fasteners such as straps, magnetic buttons, and the like. The first fixing layer may be wrapped outside the first support structure 110 to form the elastic support layer 1, and the first fixing layer may be wrapped outside the second support structure 210 to form the airflow layer 2.

The first end surface of the second support structure 210 is close to the second end surface of the elastic support layer 1 of the second support structure 210, so that airflow is circulated between the elastic support layer 1 and the airflow circulating layer 2 through the first end surface of the second support structure 210.

In some embodiments of the present disclosure, as shown in fig. 3, the air guide device further includes a guide layer 4, where the guide layer 4 is disposed between the second end surface of the elastic support layer 1 and the first end surface of the airflow circulation layer 2, and a first through-guide hole 410 is disposed on the guide layer 4. The first deflector hole 410 is used for allowing the air flow between the elastic support layer 1 and the air flow-through layer 2, that is, the air flow between the elastic support layer 1 and the air flow-through layer 2 flows through the first deflector hole 410. The shape of the first deflector hole 410 may be C-shaped, S-shaped, elongated, or the like.

As shown in fig. 4, the flow guiding layer 4 sequentially divides a plurality of airflow partitions in a direction away from a center point by taking the center point as a center, and the sizes of the airflows of the airflow partitions from the center point to the far are sequentially increased. The amount of airflow is related to the size of the airflow aperture, the area of the airflow zone to which the airflow aperture belongs, and the number of airflow apertures.

I.e. the smaller the amount of airflow in the airflow section closer to the center point of the deflector layer 4, the larger the amount of airflow in the airflow section farther from the center point of the deflector layer 4. For example, as shown in fig. 4, a schematic distribution of the first diversion holes 410 on the diversion layer 4 is shown.

At this time, as shown in fig. 5, a vent 321 is provided at a portion of the end surface of the lower cap 320 of the wrapping layer 3 corresponding to the position of the external pneumatic device. Because the central point of the diversion layer 4 corresponds to the central point of the external pneumatic device, the suction/blowing force of the central area of the diversion layer 4 is strongest, and the air flow is highest, in order to uniformly disperse the air flow in the center of the air flow to the peripheral area of the air flow, the suction/blowing force of the central area is dispersed to the peripheral area of the air flow through the sequentially increased air flow, so that the uniform dispersion of the air flow in the cushion pad is realized, and the comfortable experience of the human body refrigerating effect is improved.

In some embodiments of the present disclosure, the first end surface of the airflow circulation layer 2 is of an airtight structure, and a plurality of second diversion holes 213 penetrating through the first end surface of the airflow circulation layer 2 are disposed on the first end surface of the airflow circulation layer 2. The first end surface of the airflow through layer 2 may be the first end surface of the second support structure 210, or a portion of the second support structure 210 covered by the second fixing layer in the above embodiment. The second deflector hole 213 is used to circulate air between the elastic support layer 1 and the air flow layer 2, that is, air between the elastic support layer 1 and the air flow layer 2 flows through the second deflector hole 213. The second deflector hole 213 may have a C-shape, S-shape, or an elongated shape.

The first end face of the airflow circulation layer 2 sequentially divides a plurality of airflow subareas in a direction away from the center point by taking the center point as a circle center, the sizes of the airflow subareas from the center point to the far are sequentially increased, and the sizes of the airflow subareas are related to the sizes of the airflow holes, the areas of the airflow subareas to which the airflow holes belong and the number of the airflow holes.

Illustratively, the second deflector aperture 213 may be sized and dense such that the magnitude of the airflow volume from the near-to-far airflow zone from the center point increases in sequence. The function of the second deflector hole 213 is similar to that of the first deflector hole 410 in the above-described embodiment, and will not be described again.

The second supporting structure 210 may be made of a material having toughness and high hardness, for example, XPE material, EVA material, etc., and formed by high temperature hot pressing and stamping process, or modified plastic particles having toughness and high hardness, i.e. raw material bulk particles, or other raw materials having such properties in the market, which are toughened, reinforced, or hardened, by injection molding process. The second support structure 210 may be a hollow structure or a solid structure. The second support structure 210 can provide not only a supporting function but also protect the electronic components in the airflow through layer 2 from crushing.

As shown in fig. 7, the pneumatic assembly includes a pneumatic device 220, and the pneumatic device 220 may employ an exhaust fan for enabling air flow communication between the inside and the outside of the cushion. The control assembly 230 is electrically connected to the pneumatic device 220, and is used for controlling the pneumatic device 220 to operate, the second support structure 210 is provided with a wire arrangement slot 212, and wires between the control assembly 230 and the pneumatic device 220 can pass through the wire arrangement slot. The control assembly 230 may include a control circuit, a control chip, and a power supply circuit, and the control assembly 230 may provide power to the pneumatic device 220 and control the operation of the pneumatic device 220 through the control circuit. The control assembly 230 may also include a wireless device for receiving control instructions sent by a control terminal external to the cushion.

Illustratively, the power supply circuitry in the control assembly 230 may be connected to an external power supply via a power cord.

In an exemplary embodiment, in the case that the second supporting structure 210 is in a hollow structure, that is, the pneumatic device 220 may enable the air flow between the inside and the outside of the cushion pad through the hollow second supporting structure 210. Because the air flow between the elastic supporting layer 1 and the air flow layer 2 is circulated, the air device 220 can extract the air at the first end face of the elastic supporting layer 1 into the air flow layer 2 and exhaust the air from the side wall of the air flow layer 2, the side wall of the air flow layer 2 is perpendicular to the first end face of the air flow layer 2, and the side wall of the air flow layer 2 can be provided with an air outlet. Alternatively, the air-moving device 220 may be configured to draw air from the sidewall of the air-moving layer 2 into the air-moving layer 2 and out the first end of the flexible support layer 1.

As shown in fig. 7, in the case that the second supporting structure 210 is in a solid or hollow structure, the wind-driven device 220 is connected with a wind-driven duct 240, one end of the wind-driven duct 240 is disposed at the wind-driven device 220, and the other end is disposed at the side wall of the airflow layer 2. So that the air-driven device 220 communicates with the external space of the air flow layer 2 through the air flow duct 240. The air-moving device 220 can extract air at the first end surface of the elastic support layer 1 into the air-flowing layer 2 and discharge the air from the side wall of the air-flowing layer 2 through the air-flowing pipe 240. Or the pneumatic device 220 may be configured to draw air from the sidewall of the airflow through layer 2 through the airflow channel 240 into the airflow through layer 2 and out the first end surface of the flexible support layer 1.

In this embodiment, the air-driven device 220 is disposed inside the air-flow layer 2, so as to further increase the air permeability of the buffer layer, and avoid the stuffiness inside the buffer layer and the unsmooth air flow caused by the extruded buffer layer.

In some embodiments, in the case that the second supporting structure 210 is in a hollow structure, that is, the pneumatic device 220 may enable the air flow between the inside and the outside of the cushion pad through the hollow second supporting structure 210. Because the air flows between the elastic supporting layer 1 and the air flow layer 2, the air driving device 220 can pump the air at the first end surface of the elastic supporting layer 1 into the air flow layer 2 and exhaust the air from the bottom of the air flow layer 2, and the bottom of the air flow layer 2 can be provided with an exhaust area, i.e. the vent 321 at the lower end cover 320. Or the pneumatic device 220 may be configured to draw air at the bottom of the airflow through layer 2 into the airflow through layer 2 and out the first end surface of the flexible support layer 1. At this time, the cushion pad may be used by being overlapped with other devices, for example, by being placed above other devices, which may include a bed, a sofa, a chair, other cushions/pads, etc., and the upper surface of the other devices is provided with a tuyere corresponding to the exhaust region of the bottom of the airflow through layer 2.

The first protective cover 250 and the second protective cover 260 are typically made of a material having a certain hardness, such as a metal alloy. For example, the first protective cover 250 may be a hollow cage structure with side walls serving as support rods, so that the first protective cover 250 does not affect heat dissipation and wire connection of the control assembly 230, such as the first protective cover 250 shown in fig. 8.

As shown in fig. 9, the first end face of the second protection cover 260 and the side wall perpendicular to the first end face of the second protection cover 260 are both provided with ventilation holes 261, and the first end face of the second protection cover 260 is an end face that is close to the first end face of the airflow circulation layer 2 and parallel to the first end face of the airflow circulation layer 2. The wind gap of pneumatic device 220 upper end and the ventilative hole 261 of the first terminal surface of second safety cover 260 laminating set up, and the wind gap of pneumatic device 220 side terminal surface corresponds laminating setting with the ventilative hole 261 of the lateral wall of second safety cover 260.

It should be noted that after the first protective cover 250 and the second protective cover 260 are mounted on the second support structure 210, the first end surface of the second support structure 210 is kept substantially smooth, and the first end surface of the second support structure 210 remains substantially smooth after the first end surface of the second support structure 210 is subjected to uniform pressure.

Illustratively, the peripheral side walls and the bottom of the second fixing layer of the second supporting structure 210 are made of air-impermeable flexible fabric, and the bottom is provided with an air ventilation area at a position corresponding to the position of the pneumatic device 220.
