Description

Technical Field

[0001] This application relates to the field of cushion technology, and in particular to a cooling cushion. Background Technology

[0002] With the increasing demand for seat cushion functions, seat cushions with various functions have emerged. For example, in the hot summer, to prevent sweat from not being able to escape and causing stuffiness and discomfort due to prolonged sitting, a fan is installed inside the seat cushion. When a person sits on the seat cushion, it can deliver an airflow of a certain speed to the buttocks, thus providing a more comfortable and refreshing experience when sitting for a long time. After prolonged use, the surface of the seat cushion needs to be cleaned. Because the seat cushion contains electronic components such as fans and motors, and the seat cushion is usually a one-piece structure, there is a risk that cleaning water may seep into the electronic components during the cleaning process, which makes the cleaning of the seat cushion somewhat inconvenient.

[0022] With the increasing demand for seat cushion functions, seat cushions with various functions have emerged. For example, in the hot summer, to prevent sweat from not being able to escape and causing stuffiness and discomfort due to prolonged sitting, a fan is installed inside the seat cushion. When a person sits on the seat cushion, it can deliver an airflow of a certain speed to the buttocks, thus providing a more comfortable and refreshing experience when sitting for a long time. After prolonged use, the surface of the seat cushion needs to be cleaned. Because the seat cushion contains electronic components such as fans and motors, and the seat cushion is usually a one-piece structure, there is a risk that cleaning water may seep into the electronic components during the cleaning process, which makes the cleaning of the seat cushion somewhat inconvenient.

[0023] Based on this, refer to Figures 1-12 As shown, this application embodiment provides a cooling pad 100, which includes an air supply layer 1, a breathable layer 2, and a connector 3; wherein, the cooling pad 100 has a first direction Z extending along its thickness direction, an X direction extending along its length direction, and a Y direction extending along its width direction; as shown Figure 2As shown, the air supply layer 1 has an installation cavity, and the air supply component 13 is housed in the installation cavity. The air supply component 13 is used to generate an airflow of a certain speed. The breathable layer 2 is located on one side of the air supply layer 1 along the first direction Z, and the breathable layer 2 covers the air supply layer 1. The breathable layer 2 is connected to the air supply layer 1, so that the airflow of a certain speed generated by the air supply component 13 is blown out through the breathable layer 2, thereby achieving the effect of ventilation and cooling of the buttocks area of ​​the human body, avoiding stuffiness and discomfort when sitting for a long time in hot summer, and improving the comfort when sitting for a long time in hot summer.

[0024] In this embodiment, when the breathable layer 2 is placed on the air supply layer 1, it is fixed to the air supply layer 1 by the connector 3 to ensure that the breathable layer 2 will not slip off the air supply layer 1 during use. Specifically, the connector 3 is configured to apply a certain amount of force to the breathable layer 2 along the extension direction from the breathable layer 2 to the air supply layer 1. This force is used to press the breathable layer 2 tightly against the air supply layer 1, that is, to create a certain amount of resistance between the breathable layer 2 and the air supply layer 1, thereby fixing the breathable layer 2 to the air supply layer 1. When cleaning the breathable layer 2, the user applies a certain force to the breathable layer 2 along the extension direction from the air supply layer 1 to the breathable layer 2, causing the breathable layer 2 to move away from the air supply layer 1 along the first direction Z. This disengages the breathable layer 2 from the connector 3, allowing the breathable layer 2 to be removed from the air supply layer 1. Thus, only the breathable layer 2 needs to be cleaned. Compared to the traditional one-piece seat cushion design, this solves the problem of potential damage to built-in electronic components during cleaning, improving the convenience of cleaning.

[0025] Understandably, when it is necessary to remove the breathable layer 2 from the air supply layer 1, the force applied by the user to the breathable layer 2 along the extension direction from the air supply layer 1 to the breathable layer 2 should be greater than the force applied by the connector 3 to the air supply layer 1 along the extension direction from the breathable layer 2 to the air supply layer 1. That is, only after overcoming the force applied by the connector 3 along the air supply layer 2 to the air supply layer 1, allowing the breathable layer 2 to detach from the connector 3, can the fixing of the connector 3 to the breathable layer 2 be released, and the breathable layer 2 be removed from the air supply layer 1.

[0026] In this embodiment, as Figure 2 As shown in Figure 3, there may be one or more connectors 3. When there are multiple connectors 3, they are arranged evenly and at intervals along the periphery of the cooling pad 100, thereby improving the connection stability and reliability between the breathable layer 2 and the air supply layer 1. Optionally, in some embodiments of this application, at least two connectors 3 are provided to fix the breathable layer 2 to the air supply layer 1, so as to improve the installation stability of the breathable layer 2.

[0027] In this embodiment, the air supply layer 1 includes a shell with an installation cavity formed inside, and the air supply component 13 is disposed in the installation cavity. The shell should have a certain degree of rigidity to prevent deformation when a person sits on the breathable layer 2, ensuring the normal operation of the air supply component 13. For example, the shell can be made of a material with a certain degree of rigidity, such as rigid plastic, aluminum alloy, or engineering plastic, to ensure the structural stability of the shell. The shell is open on the side facing the breathable layer 2, or multiple support rods can be provided on the side of the shell facing the breathable layer 2. The support rods on the side facing the breathable layer 2 are flush with the side of the air supply layer 1 facing the breathable layer 2, so that when the breathable layer 2 is covered on the air supply layer 1, it can provide better support and reinforcement for the breathable layer 2.

[0028] It is understood that the breathable layer 2 in this application can be a rigid plate-like structure with multiple ventilation holes 22 evenly distributed on it for delivering the airflow generated by the air supply layer 1 to the human body. For example, the breathable layer 2 can be a porous wooden board. When multiple support rods are provided on the side of the shell facing the breathable layer 2, the breathable layer 2 can also be a flexible structure, such as a flexible composite structure, with the upper layer being a bamboo fiber woven layer (3mm thick, 1mm woven gap, sweat-absorbing and breathable) and the lower layer being a honeycomb mesh fabric (5mm thick, 6mm honeycomb hole diameter, forming an air circulation channel). The two layers are fixedly connected by ultrasonic welding, without glue, environmentally friendly and durable. In this embodiment, multiple support rods are provided on the side of the air supply layer 1 (shell) facing the breathable layer 2, so the breathable layer 2 can be made of some softer materials (the multiple support rods can support and support the soft breathable layer 2) to improve the comfort of the cooling pad 100.

[0029] Reference Figure 2 , Figure 3 As shown, in one embodiment of this application, the connector 3 includes a connecting rod 31 and a plurality of elastic pressing parts 32; wherein, the connecting rod 31 is installed on the side of the air supply layer 1 facing the breathable layer 2, and the elastic pressing parts 32 are connected to the connecting rod 31, and there are a plurality of elastic pressing parts 32, which are fixedly connected to the connecting rod 31 around the periphery of the connecting rod 31; in the first direction Z, the breathable layer 2 is provided with a through hole 21 corresponding to the position of the connector 3, such as Figure 3 As shown, the elastic pressing part 32 has a protrusion 323 that is away from the connecting rod 31; as Figure 6 As shown, in the first direction Z, the outer contour line of the protrusion 323 projected onto the air supply layer 1 is located outside the outer contour line of the perforation 21 projected onto the air supply layer 1; the breathable layer 2 is placed on the air supply layer 1, and the connecting rod 31 passes through the perforation 21 provided on the breathable layer 2, so that when the side of the breathable layer 2 facing the air supply layer 1 contacts the air supply layer 1, the protrusion 323 extends outward from inside the perforation 21, as shown. Figure 6As shown, the protrusion 323 presses against the side of the air supply layer 1 facing the perforation 21 away from the air supply layer 1 on the axial side. Thus, the elastic force of the elastic pressing part 32 applies a force to the breathable layer 2 along the extension direction from the breathable layer 2 to the air supply layer 1, and presses the breathable layer 2 tightly against the air supply layer 1, thereby achieving a fixed installation between the breathable layer 2 and the air supply layer 1.

[0030] It is understandable that, since the outer contour line of the protrusion 323 on the elastic pressing part 32 projected onto the air supply layer 1 is located outside the outer contour line of the perforation 21 projected onto the air supply layer 1, when the breathable layer 2 is placed on the air supply layer 1, that is, during the process of the connecting rod 31 extending into the perforation 21, the protrusion 323 of the elastic pressing part 32 will first be squeezed from the perforation 21 towards the axial side of the air supply layer 1, causing the elastic pressing part 32 to undergo a certain bending deformation in the direction close to the connecting rod 31, so that the protrusion 323 extends outward from the perforation 21. Then the elastic pressing part 32 returns to its deformation and presses the side of the protrusion 323 towards the air supply layer 1 against the axial side of the perforation 21 away from the air supply layer 1 (e.g., Figure 6 As shown in the figure, this achieves the application of a force along the extension direction from the air permeable layer 2 to the air supply layer 1, which is used to fix the air permeable layer 2 to the air supply layer 1.

[0031] In this embodiment, when it is necessary to remove the breathable layer 2 from the air supply layer 1, the user needs to apply a certain amount of force to the breathable layer 2 along the extension direction from the air supply layer 1 to the breathable layer 2. This force forces the elastic pressing part 32 to be squeezed from the perforation 21 away from the axial side of the air supply layer 1 and to bend again toward the connecting rod 31. As the breathable layer 2 moves away from the air supply layer 1, the connecting rod 31 and the elastic pressing part 32 are completely withdrawn from the perforation 21, thereby removing the breathable layer 2 from the air supply layer 1.

[0032] It is understandable that, such as Figure 3 As shown, the cross-sectional shape of the connecting rod 31 can be rectangular, square, or any other arbitrary shape. Only two elastic abutment parts 32 may be provided, and the two elastic abutment parts 32 are respectively connected to opposite sides of the connecting rod 31 along the X-direction; for example... Figure 2 As shown, the width of the perforation 21 along the Y direction on the breathable layer 2 and the width of the connecting rod 31 along the Y direction can be set to be the same. Thus, when the breathable layer 2 is placed on the air supply layer 1, the two opposite sides of the connecting rod 31 along the Y direction are in close contact with the opposite side walls of the corresponding perforation 21 along the Y direction. This achieves the positioning of the breathable layer 2 relative to the air supply layer 1 along the Y direction and improves the fixing effect of the breathable layer 2.

[0033] For example, the elastic pressing part 32 can be provided in three, four or more, and multiple elastic pressing parts 32 are connected around the periphery of the connecting rod 31. At this time, the periphery of the connecting rod 31 no longer contacts the inner wall of the perforation 21. When the breathable layer 2 is covered on the air supply layer 1, a certain amount of force is applied to the breathable layer 2 along the extension direction from the breathable layer 2 to the air supply layer 1 by a larger number of elastic pressing parts 32, so that the abutting force between the breathable layer 2 and the air supply layer 1 is further increased, thereby further improving the fixing effect between the breathable layer 2 and the air supply layer 1, and ensuring that the breathable layer 2 will not detach from the air supply layer 1 in the first direction Z.

[0034] In this embodiment, the elastic pressing part 32 can be a spring sheet or a structural component with elastic deformation characteristics. The elastic pressing part 32 and the connecting rod 31 can be connected and fixed by fasteners, such as bolts, screws, etc., to fix the elastic pressing part 32 on the connecting rod 31.

[0035] Reference Figure 3 , Figure 6 As shown, in one embodiment of this application, the elastic pressing part 32 includes a first connecting part 321 and a second connecting part 322; wherein, one end of the first connecting part 321 is fixedly connected to the connecting rod 31 in the direction extending from the breathable layer 2 to the air supply layer 1, and the other end of the first connecting part 321 extends in a direction away from the connecting rod 31, such as... Figure 6 As shown, the first connecting portion 321 forms an inclined extending surface on the side away from the air supply layer 1; one end of the second connecting portion 322 is connected to the end of the first connecting portion 321 away from the connecting rod 31; in the extending direction from the breathable layer 2 to the air supply layer 1, the other end of the second connecting portion 322 extends towards the connecting rod 31, and the end of the second connecting portion 322 away from the connection position with the first connecting portion 321 is spaced slightly from the connecting rod 31; Figure 6 As shown, the second connecting portion 322 also forms an inclined extending surface on the side facing the air supply layer 1; at least a portion of the first connecting portion 321 and the second connecting portion 322 away from the connecting rod 31 forms the above-mentioned protrusion 323, that is, the protrusion 323 is composed of a small section of the connection between the first connecting portion 321 and the second connecting portion 322.

[0036] In this embodiment, as Figure 5 , Figure 6As shown, when the breathable layer 2 is placed on the air supply layer 1 along the first direction Z, the perforations 21 on the breathable layer 2 and the connectors 3 on the air supply layer 1 should correspond in position. Then, the breathable layer 2 is driven to move towards the air supply layer 1 along the first direction Z. This causes the side of the perforation 21 facing the axis of the air supply layer 1 to first press against the side of the first connecting part 321 away from the air supply layer 1, and causes the first connecting part 321 to be squeezed and deformed towards the connecting rod 31 (since the second connecting part 322 is connected to the first connecting part 321, it will move slightly towards the connecting rod 31). This causes the first connecting part 321 to enter the perforation 21. As the breathable layer 2 continues to move, when the side of the breathable layer 2 facing the air supply layer 1 abuts against the air supply layer 1, as... Figure 6 As shown, at this time, the first connecting part 321 has completely extended out of the perforation 21, and the part of the second connecting part 322 connected to the first connecting part 321 also extends out of the perforation 21. That is, the protrusion 323 facing the air supply layer 1 is pressed against the perforation 21 on the side away from the air supply layer 1 under the action of elastic force. At this time, the elastic pressing part 32 composed of the first connecting part 321 and the second connecting part 322 has not yet fully recovered its deformation. Thus, the elastic pressing part 32 applies an elastic force of a certain magnitude to the side of the perforation 21 away from the air supply layer 1 through the protrusion 323. The component of this elastic force in the first direction Z is used to make the breathable layer 2 press tightly against the air supply layer 1, thereby realizing the connection and fixation between the two.

[0037] In this embodiment, when multiple elastic pressing parts 32 are provided, the multiple elastic pressing parts 32 are arranged evenly and at intervals along the periphery of the connecting rod 31. This enables the elastic force applied by the elastic pressing parts 32 to the breathable layer 2 through the protrusions 323 on the same connecting rod 31 to press against the side of the perforation 21 away from the air supply layer 1. The component of the elastic force in the direction perpendicular to the first direction Z can be balanced with each other, ensuring that the breathable layer 2 will not be displaced relative to the air supply layer 1 in the plane perpendicular to the first direction Z.

[0038] In this embodiment, when it is necessary to remove the breathable layer 2 from the air supply layer 1, the user needs to apply a force to the breathable layer 2 in the direction extending from the air supply layer 1 to the breathable layer 2. This force must be greater than the component force applied by the elastic pressing part 32 to the breathable layer 2 along the first direction Z through the protrusion 323. Figure 6As shown, the breathable layer 2 tends to move away from the air supply layer 1 in the first direction, causing the breathable layer 2 to squeeze the protrusion 323 away from the air supply layer 1 through the perforation 21, and forcing the second connecting part 322 to bend in the direction of the connecting rod 31. Since the first connecting part 321 is connected to the second connecting part 322, it will simultaneously drive the first connecting part 321 to bend in the direction of the connecting rod 31, thereby allowing the protrusion 323 to enter the perforation 21. As the breathable layer 2 is continuously driven to move in the first direction Z towards the air supply layer 1, the connecting piece 3 is completely withdrawn from the perforation 21, thereby removing the breathable layer 2 from the air supply layer 1.

[0039] Understandably, when removing the breathable layer 2 from the air supply layer 1, in order to make it easier for the protrusion 323 of the elastic pressing part 32 to enter the perforation 21, the user can simultaneously apply a certain amount of force to the breathable layer 2 in the extension direction from the air supply layer 1 to the breathable layer 2, and at the same time press the first connecting part 321 downward in the first direction Z. This makes it easier for the protrusion 323 of the elastic pressing part 32 to enter the perforation 21, further facilitating the disassembly of the breathable layer 2.

[0040] In this embodiment, as Figure 5 , Figure 6 As shown, in the first direction Z, because the connecting piece 3 extends upwards beyond the breathable layer 2, when a person sits on the breathable layer 2, the buttocks are supported by the connecting piece 3 due to its upward extension, causing discomfort. The breathable layer 2 could be made slightly thicker, such as... Figure 6 As shown, the perforation 21 is divided into a first hole 211 and a second hole 212, which are coaxially connected. The first hole 211 is located on the side of the breathable layer 2 facing the air supply layer 1, and the second hole 212 is located on the side of the breathable layer 2 away from the air supply layer 1. The size of the first hole 211 is smaller than the size of the second hole 212. For example, as shown... Figure 5 As shown, when the elastic pressing part 32 is connected to the opposite sides of the connecting rod 31 along the X direction, the size of the first hole 211 along the X direction is smaller than the size of the second hole 212 along the X direction (the sizes of the first hole 211 and the second hole 212 along the Y direction can be the same), thereby forming a clearance space along the X direction at the connection between the first hole 211 and the second hole 212 (for clearing the portion of the elastic pressing part 32 extending from the through hole 21); as Figure 6As shown, when the breathable layer 2 is installed, when the breathable layer 2 abuts against the air supply layer 1 on the side facing the air supply layer 1, the protrusion 323 of the elastic pressing part 32 abuts against the air supply layer 1 on the axial side of the first hole 211 away from the air supply layer 1. At this time, in the first direction Z, the upper end of the connector 3 does not protrude from the upper surface of the breathable layer 2, thereby ensuring that when a person sits on the breathable layer 2, they will not be supported by the connector 3, thus improving comfort.

[0041] In this embodiment, when the perforation 21 includes a first hole 211 and a second hole 212 that are connected, the end of the second hole 212 away from the first hole 211 can penetrate the breathable layer 2, or it can not penetrate the breathable layer 2. If the end of the second hole 212 away from the first hole 211 does not penetrate the breathable layer 2, then it should be satisfied that when the breathable layer 2 is covered on the air supply layer 1 and fixed by the connector 3, the connector 3 and the end of the second hole 212 away from the first hole 211 do not contact (or just contact) so as not to affect the fixing of the breathable layer 2 by the connector 3.

[0042] It is understandable that when multiple elastic pressing parts 32 are provided, and the multiple elastic pressing parts 32 are arranged at intervals around the periphery of the connecting rod 31, the outline of the second hole 212 projected onto the air supply layer 1 along the first direction Z is located outside the outline of the first hole 211 projected onto the air supply layer 1, thereby avoiding the first connecting part 321 and the partial protrusion 323.

[0043] For example, the side of the first connecting part 321 away from the air supply layer 1 can be an inclined plane or an arc-shaped surface, as long as it extends away from the connecting rod 31 in the first direction Z, so as to ensure that when the breathable layer 2 is driven to move toward the air supply layer 1 in the first direction Z, the first connecting part 321 can smoothly enter the perforation 21 under the guidance of the inclined surface when it is squeezed from the axial side of the perforation 21.

[0044] It is understandable that the first connecting part 321 and the second connecting part 322 can be integrated into one piece, that is, the elastic pressing part 32 is composed of a complete spring sheet. For example, the integrated form can be formed in one step by stamping, bending and other processes, which reduces manufacturing costs.

[0045] In this embodiment, the spring sheet is made of a material with good elasticity and fatigue resistance, such as spring steel or stainless steel.

[0046] Reference Figure 8 , Figure 9As shown, in one embodiment of this application, the connector 3 includes a magnet 33 and a magnetic conductor 34; wherein the magnet 33 is disposed in one of the air supply layer 1 and the air permeable layer 2, and the magnetic conductor 34 is disposed in the other of the air supply layer 1 and the air permeable layer 2. In the first direction Z, the magnet 33 and the magnetic conductor 34 are positioned correspondingly, and both the magnet 33 and the magnetic conductor 34 are disposed at the junction of the air permeable layer 2 and the air supply layer 1.

[0047] In this embodiment, the description is based on the example of a magnet 33 located in the air supply layer 1 and a magnetic conductive element 34 located in the breathable layer 2. Figure 8 As shown, multiple magnets 33 are arranged at intervals on the periphery of the air supply layer 1 facing the breathable layer 2, such as... Figure 9 As shown, a magnetic guide 34 corresponding to the magnet 33 is provided at the corresponding position on the side of the breathable layer 2 facing the air supply layer 1. When it is necessary to install the breathable layer 2 on the air supply layer 1, the user only needs to hold the breathable layer 2 and move it towards the air supply layer 1 in the first direction Z. Under the attraction of the magnetic force, the breathable layer 2 is attracted to the air supply layer 1. At this time, the breathable layer 2 and the air supply layer 1 are pressed tightly together under the cooperation of the magnet 33 and the magnetic guide 34, which can realize the quick installation between the breathable layer 2 and the air supply layer 1.

[0048] Understandably, when it is necessary to remove the breathable layer 2 from the air supply layer 1, the user only needs to apply a force to the breathable layer 2 in the direction extending from the air supply layer 1 to the breathable layer 2. This force overcomes the magnetic force between the magnet 33 and the magnetic conductor 34, thereby enabling the breathable layer 2 to be removed from the air supply layer 1.

[0049] For example, such as Figure 8 , Figure 9 As shown, a groove structure for accommodating and installing a magnet 33 can be provided on the side of the air supply layer 1 facing the air supply layer 2, so that the magnet 33 is completely embedded in the groove structure, thereby preventing the magnet 33 from protruding from the air supply layer 1 on the side facing the air supply layer 2. Similarly, a groove structure for accommodating and installing a magnetic conductor 34 can also be provided on the side of the air supply layer 2 facing the air supply layer 1, so that the magnetic conductor 34 is completely embedded in the groove structure, thereby preventing the magnetic conductor 34 from protruding from the air supply layer 2 on the side facing the air supply layer 1, ensuring that there is as much contact area as possible between the air supply layer 2 and the air supply layer 1, thereby enabling gravity to be transmitted downward through the contact surface between the air supply layer 2 and the air supply layer 1 when a person sits on the air supply layer 2.

[0050] It is understood that the magnet 33 and the magnetic conductor 34 can be fixed in the corresponding groove structure by adhesive or snap-fit. For example, the magnet 33 can be a neodymium iron boron magnet, a ferrite magnet, etc., and the magnetic conductor 34 can be a galvanized iron sheet, a silicon steel sheet, etc. Preferably, a waterproof membrane can be covered on the surface of the magnet 33 and the surface of the magnetic conductor 34 to prevent corrosion by sweat.

[0051] Reference Figures 1-5 , Figures 7-10 , Figures 11-12 As shown in one embodiment of this application, the cooling pad 100 further includes a limiting member 4, which is used to restrict the movement of the breathable layer 2 relative to the air supply layer 1 in a plane perpendicular to the first direction Z.

[0052] In this embodiment, the main function of the connector 3 is to apply a certain force along the first direction Z and hold the breathable layer 2 against the air supply layer 1, thereby fixing the breathable layer 2 and the air supply layer 1. However, the connection between the breathable layer 2 and the air supply layer 1 may not be stable enough by the force provided by the connector 3 along the first direction Z. In particular, when the breathable layer 2 is subjected to an external force along the plane perpendicular to the first direction Z, it may cause the breathable layer 2 to shift relative to the air supply layer 1.

[0053] In this embodiment, by setting a limiting member 4, the relative position of the breathable layer 2 to the air supply layer 1 is limited in a plane perpendicular to the first direction Z, so as to ensure that when a person sits on the breathable layer 2 and has a back-and-forth swaying motion, the breathable layer 2 will not move relative to the air supply layer 1 in a plane perpendicular to the first direction Z, thereby improving the user experience of the cooling pad 100.

[0054] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in one embodiment of this application, the limiting member 4 includes a guide post 41 and a guide hole 42; wherein, the guide post 41 extends along the first direction Z and is disposed on one of the air supply layer 1 and the breathable layer 2, and the guide hole 42 also extends along the first direction Z and penetrates at least a portion of the other of the air supply layer 1 and the breathable layer 2 along the first direction Z, such that the guide post 41 and the guide hole 42 are positioned correspondingly in the first direction Z.

[0055] In this embodiment, the description is based on the example of guide post 41 located in air supply layer 1 and guide hole 42 located in air permeable layer 2. Figure 1 , Figure 2 , Figure 4 As shown, the guide post 41 is located at the corner of the air supply layer 1, or it can be located at any position around the air supply layer 1. When the permeable layer 2 is placed on the air supply layer 1, the guide post 41 is inserted into the corresponding guide hole 42, as shown. Figure 5 As shown, this achieves the limitation of the position of the breathable layer 2 relative to the air supply layer 1 in a plane perpendicular to the first direction Z, ensuring that there is no relative displacement between the breathable layer 2 and the air supply layer 1.

[0056] It is understandable that when the breathable layer 2 is placed on the air supply layer 1, the guide post 41 should not protrude from the guide hole 42, so as to avoid the user feeling uncomfortable when sitting on the breathable layer 2 due to the support from the guide post 41.

[0057] Reference Figures 7-10 As shown, in one embodiment of this application, the limiting member 4 includes a limiting frame 43, which is connected to the side of the air supply layer 1 facing the breathable layer 2. The breathable layer 2 covers the air supply layer 1. In the first direction Z, at least a portion of the periphery of the breathable layer 2 is in contact with the inner wall of the limiting frame 43, thereby limiting the breathable layer 2 in the plane perpendicular to the first direction Z.

[0058] It is understandable that when the breathable layer 2 is placed on the air supply layer 1, in the first direction Z, the breathable layer 2 can be completely embedded in the limiting frame 43, or the breathable layer 2 can be partially embedded in the limiting frame 43 (at this time, the side of the breathable layer 2 away from the air supply layer 1 will protrude from the limiting frame 43). Preferably, in this embodiment, the height of the breathable layer 2 along the first direction Z and the depth of the limiting frame 43 are set to be the same, so that when the breathable layer 2 is placed on the air supply layer 1, the upper surface of the breathable layer 2 and the upper surface of the limiting frame 43 remain flush, thereby improving the comfort when sitting on the cooling mat 100.

[0059] Or, such as Figure 11 , Figure 12 As shown, the limiting frame 43 can also be connected to the side of the breathable layer 2 facing the air supply layer 1. The breathable layer 2 covers the air supply layer 1 in the first direction Z, so that at least a portion of the periphery of the air supply layer 1 is in contact with the inner wall of the limiting frame 43. Thus, the limiting frame 43 can also limit the breathable layer 2 in the plane perpendicular to the first direction Z.

[0060] In this embodiment, the limiting frame 43 and the breathable layer 2 or the limiting frame 43 and the air supply layer 1 can be integrated or separated. When separated, they can be connected and fixed by welding or fasteners.

[0061] Reference Figure 2 , Figure 8 As shown in one embodiment of this application, the cooling pad 100 also includes a protective net 5, which is disposed between the air supply component 13 and the breathable layer 2. The main function of the protective net 5 is to prevent debris from entering the air supply layer 1 from the breathable layer 2 and falling onto the air supply component 13, thereby avoiding damage to the air supply component 13 due to debris.

[0062] Understandably, by setting the small mesh openings on the protective net 5, some small debris, such as small particles, hair, and fibers, can be filtered out to prevent these debris from falling onto the air supply component 13 and damaging the high-speed rotating air supply component 13 (fan). The mesh openings of the protective net 5 should be small enough to effectively filter small debris. The mesh size can be selected according to actual needs, such as a mesh diameter of 0.5mm to 1mm. The protective net 5 should be made of durable, breathable, and easy-to-clean materials, such as stainless steel mesh, nylon mesh, or polyester mesh.

[0063] In this embodiment, the protective net 5 is configured such that in the first direction Z, the protective net 5 at least covers the air supply component 13. That is, in the first direction Z, the outer contour line of the orthographic projection of the protective net 5 on the air supply layer 1 coincides with the outer contour line of the orthographic projection of the air supply component 13 on the air supply layer 1, or the outer contour line of the orthographic projection of the protective net 5 on the air supply layer 1 is located outside the outer contour line of the orthographic projection of the air supply component 13 on the air supply layer 1, thereby achieving the coverage of the air supply component 13.

[0064] Understandably, the area of ​​protective netting 5 should not be too large, such as... Figure 10 , Figure 12 As shown, since the mesh on the protective net 5 is relatively small, if the area of ​​the protective net 5 is too large, it will affect the air supply component 13 from supplying air to the breathable layer 2, hinder the smooth passage of airflow, and affect the air supply effect of the air supply component 13 to the breathable layer 2.

[0065] In this embodiment, preferably, the area of ​​the protective net 5 is set slightly larger than the area of ​​the air supply component 13. This not only effectively filters impurities from the air supply component 13 but also diffuses the airflow delivered by the air supply component 13 to a certain extent. Figure 10 As shown, when the air supply component 13 delivers airflow toward the protective net 5, due to the relatively small mesh size of the protective net 5, some airflow can pass through the protective net 5 and continue to move toward the breathable layer 2. However, another part of the airflow cannot pass through the small holes in the protective net 5 in time, and under the guidance of the protective net 5, it diffuses to both sides of the protective net 5. This allows some airflow to be delivered to the breathable layer 2 from a position offset from the protective net 5, thereby enabling the airflow to flow toward the breathable layer 2 as evenly as possible. By evenly distributing the airflow, the air supply efficiency can be improved, ensuring that the entire breathable layer 2 can obtain sufficient cooling effect.

[0066] In this embodiment, the protective net 5 can be installed inside the air supply layer 1 or on the side of the breathable layer 2 facing the air supply layer 1. The protective net 5 can be fixedly installed inside the air supply layer 1 or on the side of the breathable layer 2 facing the air supply layer 1 by means of a buckle, or it can be installed by means of fasteners, so that the protective net 5 can be removed for easy cleaning.

[0067] Reference Figure 4 , Figure 9 As shown, in one embodiment of this application, the cooling mat 100 further includes an anti-slip component 6. In the first direction Z, the anti-slip component 6 is disposed on the side of the air supply layer 1 away from the breathable layer 2, which can effectively increase the friction between the cooling mat 100 and the seat surface and prevent the cooling mat 100 from sliding.

[0068] For example, the anti-slip component 6 can be made of a material with a high coefficient of friction, such as silicone. Silicone not only has good anti-slip properties, but also has softness and elasticity, and can adapt to different seat surfaces. The anti-slip components 6 can be arrayed on the side of the air supply layer 1 away from the breathable layer 2. Through the synergistic effect of multiple anti-slip components 6, the anti-slip effect can be further improved.

[0069] Understandably, the anti-slip component 6 can be fixed to the side of the air supply layer 1 away from the breathable layer 2 by means of adhesive bonding, hot pressing, or embedding.

[0070] Reference Figure 2 , Figure 4 As shown in one embodiment of this application, as Figure 10 As shown, an air inlet 11 is provided at the bottom of the housing, and the air inlet 11 and the air supply component 13 are positioned correspondingly. It can be understood that, as Figure 4 , Figure 9 , Figure 10 As shown, in order to prevent the air supply component 13 from sucking dust and debris from the external environment into the air supply layer 1 through the air inlet 11, a dustproof net 12 can be provided at the bottom of the air supply layer 1 at the position corresponding to the air inlet 11. This can effectively filter the air entering the air supply layer 1, protect the air supply component 13 from damage by dust and debris, and extend its service life.

[0071] In this embodiment, since the air inlet 11 is located at the bottom of the housing, when the air supply layer 1 is placed on the seat, a certain distance should be maintained between the bottom of the housing and the seat to ensure that when the air supply component 13 is working, air from the outside environment can be drawn into the air supply layer 1 through the air inlet 11. For example, a support leg can be provided on the side of the housing away from the breathable layer 2 so that a certain distance is maintained between the air inlet 11 at the bottom of the housing and the seat surface, so that outside air can be drawn into the air supply layer 1 through the air inlet 11 under the action of the air supply component 13. Alternatively, when the anti-slip component 6 is provided at the bottom of the air supply layer 1, the anti-slip component 6 acts as a support leg. When the air supply layer 1 is placed on the seat surface, the multiple arrayed anti-slip components 6 serve both as anti-slip and as support legs, that is, a certain distance is maintained between the air inlet 11 at the bottom of the housing and the seat surface, so that outside air can be drawn into the air supply layer 1 through the air inlet 11 under the action of the air supply component 13.

[0072] For example, in order to further improve the functionality of the cooling pad 100, a vibration module can be provided on the breathable layer 2. For example, the vibration module can be designed as an independent unit and embedded in the breathable layer 2, and driven by a micro motor to achieve periodic vibration. The vibration module can be made of soft and elastic materials such as silicone. Silicone not only has a good feel, but also reduces the stimulation of vibration on the user's skin.

[0073] For example, three vibration modules can be provided on the breathable layer 2, corresponding to the "Chengfu" acupoint (both sides of the buttocks) and "Changqiang" acupoint (at the coccyx) of the human body, to relieve the stiffness of the buttock muscles caused by prolonged sitting and improve the comfort of prolonged sitting.

[0074] In this embodiment, the size of the cooling pad 100 can be designed to be larger so that when a person sits on the cooling pad 100, at least part of the edge of the breathable layer 2 is not covered by the person's buttocks. This ensures that airflow can be delivered upward from the edge of the breathable layer 2 where it is not covered by the person's buttocks, thereby achieving a more comprehensive ventilation effect.

[0075] Reference Figure 10 , Figure 12 As shown in one embodiment of this application, the cooling pad 100 also includes a power supply component for providing power to electronic devices such as the air supply component 13 and the vibration module. The power supply component can be set at a suitable position within the air supply layer 1. The power supply component can be a rechargeable battery (such as a lithium-ion battery) with high energy density, long lifespan, and fast charging characteristics.

[0076] In this embodiment, as Figure 10 , Figure 12 As shown, the cooling pad 100 also includes a cooling component 7, which is installed in a suitable position within the air supply layer 1, and can significantly improve the cooling effect of the cooling pad 100; a temperature sensor can also be provided at the part of the breathable layer 2 that comes into contact with the human body to detect the human body contact temperature in real time; a display screen can be provided on the outer wall of the air supply layer 1 to display the temperature measured by the temperature sensor in real time.

[0077] For example, the cooling element 7 may be a semiconductor cooling chip, which is powered by a power supply component to activate the cooling function when needed.

[0078] In this embodiment, the cooling component 7 can work independently and perform cooling by switching the current on and off, thereby helping to cool the human body; or the cooling component 7 can work in conjunction with the air supply component 13, that is, the cooling component 7 and the air supply component 13 work simultaneously, with the cooling component 7 responsible for cooling, and the air supply component 13 used to blow the cold air evenly onto the breathable layer 2 to enhance the cooling effect, which is suitable for cooling needs in high-temperature environments; thus, the cooling or air supply function can be flexibly selected according to the user's specific needs, improving the applicability of the cooling pad 100 and the user experience.

[0079] It is understood that the air supply component 13 in this application is a fan, and a controller for controlling the operation of the fan and the operation of the cooling component 7 is provided on the outer wall of the air supply layer 1. The user controls the operation of the above components through the controller.

Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
