Description

Technical Field

[0001] The utility model relates to a polymer fiber pad product, in particular to a soft seat pad with ventilation function. Background Art

[0002] The polymer fiber pad is a polymer material that is heated and melted. After being spun through a spinning plate, the fiber filaments are entangled to form bonding points, and aggregated to form a three-dimensional ring body with irregular holes. This structure has high support strength, good air permeability, is not easy to breed bacteria and is easier to clean. It has the elasticity of a spring pad and the comfort of a latex pad. With the improvement of the process of polymer fiber pads, polymer fiber pads have high elasticity, high support, high fatigue resistance and good air permeability, and have been widely used in the market. When polymer fiber pads are used in seat cushions, they need to be cut into a size that matches the seat surface of the seat to obtain an air fiber cushion. The fiber ends at the cut surface of the air fiber cushion will form a spike structure, and the clothes on the legs are easily punctured by the spike structure, which brings a poor experience to users. To solve this problem, the fiber ends are generally isolated by covering the air fiber cushion with a cloth cover. However, due to the presence of the cover, the overall heat dissipation of the soft cushion will be reduced. Publication No. CN222522533U and Publication No. CN222548919U both disclose a technical solution for increasing the heat dissipation of an air fiber cushion, namely, an air supply plate is provided under the cushion, a fan is fixedly mounted on the air supply plate, and the airflow blown out by the fan is guided into the air fiber cushion through the drainage structure on the air supply plate, thereby accelerating the air flow in the air fiber cushion, and further improving the heat dissipation of the soft cushion.

[0024] The utility model is described in detail below in conjunction with the accompanying drawings. The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be interpreted as limiting the utility model. The directional terms such as left, middle, right, top, and bottom in the embodiments of the utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0025] First embodiment:

[0026] A soft cushion with ventilation function, such as Figure 1 and Figure 2As shown, it includes an air fiber cushion 2 and a cover 1. In this embodiment, the size of the air fiber cushion 2 is 450mm long * 450mm wide * 50mm high, and it is formed by a three-dimensional ring-connected body 23 with irregular holes 22. The three-dimensional ring-connected body 23 on the side of the air fiber cushion 2 is cut off to form a fiber filament end. The cover 1 is arranged on the top surface of the air fiber cushion 2 and covers the side of the air fiber cushion 2, and the fiber filament ends on the side of the air fiber cushion 2 are blocked on the inner side of the cover 1 to prevent the fiber filament ends from passing through the cover 1 and piercing the user's legs. The top surface of the cover 1 is a breathable structure, specifically a mesh cloth or Bamboo board / wooden bead woven pad; a miniature fan 3 is arranged in the middle of the front side of the air fiber cushion 2; the utility model can be placed on the seat surface of a chair used for daily office work, and when the user uses it, the fan 3 can just make way for the user's thighs, without occupying the use area of ​​the air fiber cushion 2; when the side of the cover 1 is made of a partially breathable material, the local breathable area on the side of the cover 1 can correspond to the air inlet of the fan 3, so as to facilitate the air intake of the fan 3; in other embodiments, when the side of the cover 1 is made of an airtight material, the fan 3 can absorb air from various places in the air fiber cushion 2 through the irregular holes 22, and the corresponding fan 3 on the air fiber cushion 2 A receiving groove 21 matching with the fan 3 is opened at the position, and the fan 3 is received and fixedly installed in the corresponding receiving groove 21. Due to the shielding of the side of the air fiber cushion 2 by the cover 1, when the air inlet and the air outlet of the fan 3 are both located in the air fiber cushion 2, the air inlet and the air outlet of the fan 3 can accelerate the air flow in the air fiber cushion 2; the fan 3 located in the middle of the front side of the air fiber cushion 2 is used to blow air to the central area of ​​the air fiber cushion 2 through the irregular holes 22 in the air fiber cushion 2; when the airflow blown out by the fan 3 passes through the irregular holes 22 in the air fiber cushion 2, the three-dimensional ring connection body 23 performs turbulence, Thereby, the air flow is diffused in the air fiber cushion 2, and the heat dissipation area of ​​the fan 3 to the air fiber cushion 2 is increased. The air fiber cushion 2 is cooled by the fan 3, and the fan 3 can also blow air directly above the accommodating groove 21, so as to blow air to the user; that is, when the air permeability of the top surface of the cover 1 is poor, the fan 3 can heat the air fiber cushion 2 by increasing the gas flow in the air fiber cushion 2. When the air permeability of the top surface of the cover 1 is good, the air flow in the air fiber cushion 2 can pass through the cover 1 to supply air to the user, thereby achieving air supply and cooling to specific areas of the user's body, or reducing the temperature of the heat concentrated area directly under the user's buttocks.

[0027] The fan 3 is a centrifugal fan or an axial flow fan. At present, the miniature size of the centrifugal fan can be 20mm long * 20mm wide * 6mm high, and the miniature size of the axial flow fan can be 25mm long * 25mm wide * 10mm high. The voltage of the fan 3 is 5V. When the fan 3 is an axial flow fan, the fan 3 is arranged vertically, and the thickness of the air fiber cushion 2 is greater than or equal to the height of the fan 3; when the fan 3 is a centrifugal fan, the fan 3 is arranged horizontally, and the thickness of the air fiber cushion 2 is greater than or equal to the thickness of the fan 3; thereby avoiding the fan 3 protruding from the air fiber cushion 2 to cause a bulge on the top surface of the cover 1, affecting the beauty of the utility model or causing discomfort to the user; the three-dimensional annular body 23 located at the side walls on both sides of the accommodating groove 21 clamps the fan 3 by elasticity, thereby stably clamping the fan 3 in the accommodating groove 21; in this embodiment, the accommodating groove 21 is a through groove, and when the accommodating groove 21 is a sink groove with only an upper end opening, the bottom of the fan 3 contacts the bottom of the sink groove.

[0028] Combination Figure 1 and Figure 3 As shown, a wing-shaped storage pocket 4 is fixedly connected to the side of the cover 1, and the storage pocket 4 is used to store the power connection line 52 of the fan 3, or to store the power connection line 52 and the power supply battery of the fan 3. In this embodiment, the fan 3 is electrically connected to the PCB board through the branch wire 51, one end of the power connection line 52 is electrically connected to the PCB board, and the other end of the power connection line 52 is connected to the power supply or the power supply battery, wherein the power connection line 52 and the branch wire 51 are both plugged into the PCB board through quick-plug connectors, the PCB board is accommodated in the card slot 5, and the card slot 5 is then embedded in the side wall of the air fiber cushion 2, so as to fix the PCB board, and the power connection line 52 and the branch wire 51 can be snapped onto the bottom surface of the air fiber cushion 2; when in use, the electric energy is sequentially transmitted through the power connection line 5 2. The power flows into the fan 3 after the PCB board and the branch wire 51, thereby driving the fan 3; a control switch 53 and a USB plug 54 are set on the power connection line 52 to control the start and stop of the fan 3. When a power supply battery (power bank) is used to power the fan 3, the power connection line 52 and the power supply battery can be stored in the storage pocket 4; when not in use, the power connection line 52 and the control switch 53 and USB plug 54 thereon can be stored in the storage pocket 4; in other application scenarios, the fan can be powered by the USB interface of the computer main chassis or the USB interface of the voltage conversion plug.

[0029] Second embodiment:

[0030] Other technical features are the same as those of the first embodiment, such as Figure 4As shown, the fan 3 is a centrifugal fan, and the fan located in the middle of the front side of the air fiber cushion 2 is used to blow air obliquely upward and backward through the irregular holes 22 in the air fiber cushion 2, and a clearance opening 11 is opened in the middle of the front side of the cover 1. The clearance opening 11 is used to make way for the wind blown out by the fan located in the middle of the front side of the air fiber cushion 2; in this way, the cover 1 can be prevented from affecting the ventilation effect at a specific position of the air fiber cushion 2, thereby meeting the high cooling demand at a specific position of the body; in addition, the clearance opening 11 can also cooperate with the fan 3 to optimize the heat dissipation effect in the cover 1; in this embodiment, the cover 1 is not provided with a bottom surface, and in other embodiments, the cover 1 can also be provided with a bottom surface.

[0031] Third embodiment:

[0032] Other technical features are the same as those of the first embodiment, such as Figure 5 As shown, when the cover 1 is provided with a bottom surface, the cover 1 is fixedly connected to the first cloth layer and forms a closed first interlayer 101 therebetween, the air fiber cushion 2 and the branch wire 51 are located in the first interlayer, at this time, the branch wire 51 may not be clamped with the bottom surface of the air fiber cushion 2; the first cloth layer is connected to the second cloth layer and forms a second interlayer 102 therebetween, and the second interlayer 102 is used as a storage space for a handbag or a messenger bag; in some usage scenarios where the seats are not fixed, such as university campuses, this embodiment can be used as a handbag or a messenger bag to be brought to the classroom, and when in use, after taking out the books, pens and other items in the storage space, this embodiment can be used as a cushion; wherein, the handle 103 of the handbag / messenger bag is preferably made of soft material, and can naturally droop in front of the seat of the chair to avoid affecting the user's leg posture.

[0033] Fourth embodiment:

[0034] Other technical features are the same as those of the first embodiment. Miniature fans 3 are also provided at the left rear corner and the right rear corner of the air fiber cushion 2. When the user is in use, these fans 3 can just make way for the user's buttocks and do not occupy the use area of ​​the air fiber cushion 2; the fans located at the left rear corner and the right rear corner of the air fiber cushion 2 are both used to blow air toward the central area of ​​the air fiber cushion 2 through the irregular holes 22 in the air fiber cushion 2; after the fans 3 rotate, the fans 3 located at the left rear corner and the right rear corner of the air fiber cushion are mainly used to dissipate heat to the central area of ​​the air fiber cushion 2, thereby reducing the temperature of the heat concentrated area directly under the user's buttocks, and in conjunction with the fan in the middle of the front side of the air fiber cushion 2, the heat dissipation effect of the air fiber cushion 2 can be increased. At this time, the fan 3 located in the middle of the front side of the air fiber cushion 2 is preferably used to blow air toward the top of the accommodating groove 21. Among them, when the air fiber cushion 2 is of some smaller sizes, such as a length, width and height of 350mm*250mm*30mm respectively, a fan 3 is only provided in the middle of the front side of the air fiber cushion 2 to effectively dissipate the heat of the air fiber cushion 2, and the fan 3 does not need to be operated at high power; in some larger-sized cushions, if the silent effect of the fan 3 is poor, when the fan 3 is operated at high power, the noise is relatively large, and when it is operated at low power, it cannot meet the user's heat dissipation needs in some hotter environments. Therefore, by providing the fan 3 at the left rear corner and the right rear corner of the air fiber cushion 2, the large-sized air fiber cushion 2 is cooled in multiple directions in cooperation with the fan in the middle of the front side of the air fiber cushion 2, thereby improving the heat dissipation effect of the air fiber cushion 2 and effectively controlling the noise of the fan 3. In addition, in order to expand the air supply effect of the fan 3 to the central area of ​​the air fiber cushion 2, an air guide channel (not shown in the figure) is arranged in the air fiber cushion 2. The air guide channel is horizontally arranged, and the air guide channel is a straight structure or an arc structure. The longitudinal section of the air guide channel is preferably circular. The diameter of the air guide channel is smaller than the thickness of the air fiber cushion 2 and preferably smaller than one third of the thickness of the air fiber cushion 2 to ensure the compression resistance of the air fiber cushion 2. One end of the air guide channel is located in the central area of ​​the air fiber cushion 2, and the other end of the air guide channel corresponds to the fan outlet at the left rear corner or the right rear corner of the air fiber cushion 2. The other end port of the air guide channel is connected to the corresponding accommodating groove 21.

[0035] Fifth embodiment:

[0036] Other technical features are the same as those of the fourth embodiment. Figures 6 to 9As shown, the fan 3 is fixedly connected to the accommodating groove 21 through a fixing frame, and the accommodating groove 21 can be located at the edge of the air fiber cushion 2 or on the side of the air fiber cushion 2; the fixing frame includes a fixing portion 6 and a clamping portion 61 distributed on the fixing portion 6, the fixing portion 6 is fixedly connected to the fan 3, and when the fixing portion 6 is attached to the side where the air outlet or air inlet of the fan 3 is located, an opening 62 for making way for the air outlet or air inlet is opened on the fixing portion 6; the clamping portion 61 is located on the outside of the fan 3 and extends in a direction away from the fan 3, the clamping portion 61 is inserted into the air fiber cushion 2 from the side wall of the accommodating groove 21, the clamping portion 61 penetrates into the irregular cavity 22 of the air fiber cushion 2 and is restricted in the irregular cavity 22 by the three-dimensional annular body 23 of the air fiber cushion 2, and these immovable clamping portions 61 enable the fixing frame and the corresponding fan 3 to be fixedly installed and positioned in the accommodating groove 21. The fixing part 6 is in the shape of a plate, a frame or a slot. The fixing part 6 is connected to the shell of the fan 3 by integral injection molding, or by bonding with double-sided tape / structural adhesive, or by bolting, or by snapping through a slot, or the fan 3 is sleeved in the fixing part 6 and the two are interference-fitted. It is most preferred that the two are sleeved and then interference-fitted. There are at least two snap-fit ​​parts 61, and the snap-fit ​​parts 61 correspond to at least two different sides of the fan 3, so that the snap-fit ​​parts 61 limit the fan 3 from two different directions, thereby improving the stability of the fan 3 in the accommodating groove 21. The snap-fit ​​part 61 is in the shape of a rod or a plate. The snap-fit ​​part 61 is preferably in the shape of a rod, so that the three-dimensional annular body 23 can avoid it, thereby facilitating the insertion of the snap-fit ​​part 61 into the irregular cavity 22 in the air fiber cushion 2.
