Description

Technical Field

[0001] This utility model relates to the field of bedding technology, and in particular to a mat. Background Technology

[0002] A mattress is a common bedding item used in daily life. It is usually placed on the bed to provide support and improve lying comfort. In the hot summer, when a person lies on a mattress, the body is in close contact with the mattress, which can cause a feeling of stuffiness and reduce sleep comfort.

[0003] There is a type of air-cooled mattress with internal ventilation that removes heat from the mattress surface through internal airflow, thus providing a cooling sensation. However, the internal structure of existing air-cooled mattresses is relatively simple, making it easy for walls or other objects to block the air vents. This results in poor internal airflow and unsatisfactory heat dissipation, failing to meet people's needs.

[0004] Therefore, there is an urgent need to design a mattress to solve the aforementioned problems in existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a mat that can prevent the air outlet from being blocked by walls or other objects, thereby ensuring the air circulation inside the mat.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a mat, comprising:

[0008] The pad has a flow channel inside, and has a head end and a tail end. The head end has an air inlet, and the tail end has an air outlet. The air outlet is connected to the air inlet through the flow channel.

[0009] A fan is positioned facing the air outlet. A proximity plate is provided on the side of the fan away from the pad. A ventilation hole is provided on the proximity plate, facing the fan and extending away from the pad. The end of the proximity plate away from the pad is spaced apart from the ventilation hole.

[0010] Preferably, the angle between the approach plate and the pad is less than 180 degrees and not equal to 90 degrees.

[0011] Preferably, the mat further includes an air outlet assembly connected to the mat body. The air outlet assembly has an inlet and a receiving cavity. The inlet is positioned opposite the air outlet. The proximity plate is disposed on the air outlet assembly. The fan is disposed on the receiving cavity. The ventilation hole communicates with the inlet through the receiving cavity.

[0012] Preferably, the air outlet assembly includes a mounting shell and a contact plate, wherein the mounting shell is fixedly connected to the pad body, and the contact plate is fixedly connected to the side of the mounting shell opposite to the pad body;

[0013] The mounting shell and the approach plate enclose the receiving cavity, and the inlet is located in the mounting shell.

[0014] Preferably, the accommodating cavity includes a front chamber and a rear chamber that communicate with each other. The front chamber is connected to the air outlet through the inlet, and the rear chamber is connected to the outside through the ventilation hole. The fan is disposed in the rear chamber, and the cross-sectional area of ​​the front chamber gradually increases along the airflow direction.

[0015] Preferably, a connecting rib is provided in the rear chamber, the connecting rib is fixedly connected to the air outlet assembly, and the connecting rib is arranged around the fan, and the fan is sealed to the connecting rib.

[0016] Preferably, the length of the air inlet is not less than half the width of the pad, and the air inlet is symmetrically arranged with respect to the first axis.

[0017] Preferably, multiple air outlets are provided, and the multiple air outlets are symmetrically arranged on both sides of the tail end with respect to the first axis.

[0018] Preferably, the mat further includes a control unit, which includes a controller and a control line. The controller is electrically connected to the fan via the control line, and at least a portion of the control line is disposed inside the mat body. The controller is used to output electrical signals.

[0019] Preferably, the inside of the pad is provided with an elastic strap, and the control line located inside the pad passes through the elastic strap.

[0020] The beneficial effects of this utility model are as follows:

[0021] The mat provided by this utility model includes a mat body and a fan. The mat body has internal circulation channels. Since the air inlet at the head end is connected to the air outlet at the tail end through the circulation channels, and the fan is positioned directly opposite the air outlet, the mat can form an airflow path along the air inlet, circulation channels, and air outlet under the action of the fan. This removes heat from the surface of the mat body, thereby reducing the body surface temperature and improving sleep comfort. Since a proximity plate is provided on the side of the fan away from the mat body, and ventilation holes are opened on the proximity plate directly opposite the fan, the airflow driven by the fan can be blown out through the ventilation holes. Since the end of the proximity plate away from the mat body is spaced apart from the ventilation holes along the direction away from the mat body, the ventilation holes are located between the end of the proximity plate and the mat body. When the mat is placed flat on a flat structure, even if its side is against a wall, the ventilation holes on the proximity plate will not be blocked, but will be located in the space between the end of the proximity plate and the mat body, thus continuing to blow air outward, ensuring the air circulation inside the mat, and thereby improving the heat dissipation effect of the mat.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] like Figures 1 to 5As shown, this utility model provides a mat, which includes a mat body 1 and a fan 2. The mat body 1 has a flow channel inside. The mat body 1 has a head end 11 and a tail end 12. An air inlet is opened on the head end 11 and an air outlet is opened on the tail end 12. The air outlet is connected to the air inlet through the flow channel. The fan 2 is arranged facing the air outlet. A proximity plate 32 is arranged on the side of the fan 2 away from the mat body 1. A ventilation hole 321 is opened on the proximity plate 32. The ventilation hole 321 is arranged facing the fan 2. Along the direction away from the mat body 1, the end of the proximity plate 32 away from the mat body 1 is spaced apart from the ventilation hole 321. In this embodiment, since the air inlet at the head end 11 is connected to the air outlet at the tail end 12 through a flow channel, and a fan 2 is provided directly opposite the air outlet, the mat can form an airflow path along the air inlet, flow channel, and air outlet under the action of the fan 2, thereby removing heat from the surface of the mat 1, thus reducing the body surface temperature and improving sleep comfort. Since a proximity plate 32 is provided on the side of the fan 2 away from the mat 1, and a ventilation hole 321 is opened on the proximity plate 32 directly opposite the fan 2, the airflow driven by the fan 2 can pass through the ventilation... Ventilation holes 321 are blown out. Since the end of the approach plate 32 away from the pad 1 is spaced apart from the ventilation hole 321 along the direction away from the pad 1, the ventilation hole 321 is located between the end of the approach plate 32 and the pad 1. When the pad is laid flat on a planar structure, even if its side is against the wall, the ventilation hole 321 on its approach plate 32 will not be blocked, but will be located in the space between the end of the approach plate 32 and the pad 1, so that airflow can continue to be blown out, ensuring the air circulation inside the pad, thereby improving the heat dissipation effect of the pad.

[0037] In this embodiment, the angle between the approach plate 32 and the pad 1 is less than 180 degrees and not equal to 90 degrees. Since the angle between the approach plate 32 and the pad 1 is less than 180 degrees and not equal to 90 degrees, the approach plate 32 and the pad 1 are connected at an incline. When the pad is placed flat on a planar structure, even if its side is against the wall, the outermost end of the approach plate 32 will be against the wall to avoid the ventilation hole 321 being blocked. Therefore, the ventilation hole 321 can blow air outward at an incline angle.

[0038] In another embodiment, the approach plate 32 is vertically connected to the pad 1. The approach plate 32 is provided with a protruding abutment. The end of the abutment is farther away from the pad 1 than the ventilation hole 321. Therefore, when the pad is placed against the wall, the abutment will abut against the wall, thereby forming a space between the wall and the pad 1 for the ventilation hole 321 to vent air, preventing the ventilation hole 321 from being blocked by the wall, and ensuring the air circulation inside the pad 1.

[0039] Specifically, the pad 1 is made of thermoplastic elastomer or polyethylene commonly used in the art, commonly known as 4D air fiber. The surface of the pad 1 is sealed with an airtight fabric or thermoplastic material, with only the air inlet at the head end 11 and the air outlet at the tail end 12 exposed. The interior of the pad 1 is filled with polymer fiber filaments, thus forming a porous elastic structure. Air flows freely between the polymer fiber filaments in the direction from the air inlet to the air outlet, forming numerous airflow channels, thereby ensuring airflow and heat dissipation. The pad 1 provides sufficient support and rebound to the human body while ensuring airflow. The head end 11 and the tail end 12 are the two ends of the pad 1 along its length. When lying down, the head of the human body is at the head end 11 and the feet are at the tail end 12.

[0040] Furthermore, such as Figures 3 to 5 As shown, the mat also includes an air outlet assembly 3, which is connected to the mat body 1. The air outlet assembly 3 has an inlet and a receiving cavity 31. The inlet is positioned directly opposite the air outlet. A proximity plate 32 is disposed on the air outlet assembly 3, and a fan 2 is disposed in the receiving cavity 31. A ventilation hole 321 is connected to the inlet through the receiving cavity 31. Specifically, the air outlet assembly 3 is connected to the air outlet of the mat body 1, and the fan 2 is disposed in the receiving cavity 31 of the air outlet assembly 3, thereby ensuring that the fan 2 effectively draws air from the air outlet to ensure the airflow effect inside the mat body 1.

[0041] Specifically, such as Figures 3 to 5 As shown, the air outlet assembly 3 includes a mounting shell 33 and a contact plate 32. The mounting shell 33 is fixedly connected to the pad 1, and the contact plate 32 is fixedly connected to the side of the mounting shell 33 facing away from the pad 1. The mounting shell 33 and the contact plate 32 enclose a cavity 31, with an inlet located in the mounting shell 33. In this embodiment, the mounting shell 33 includes an upper shell and a lower shell. The upper shell is connected to the upper surface of the pad 1, and the lower shell is connected to the lower surface of the pad 1. The contact plate 32 is inclined and its two ends are respectively connected to the upper shell and the lower shell, thereby enclosing a cavity 31 at the air outlet of the pad 1. In this embodiment, the angle between the contact plate 32 and the pad 1 is less than 90 degrees. Therefore, when the pad 1 is laid flat and abuts against the side wall, the ventilation holes 321 on the contact plate 32 can still discharge air obliquely upwards, thus not affecting the air circulation inside the pad 1.

[0042] To further improve the driving effect of fan 2 on the air in accommodating cavity 31, such as Figure 3As shown, the accommodating cavity 31 includes a front chamber 311 and a rear chamber 312 that are connected. The front chamber 311 is connected to the air outlet through an inlet, and the rear chamber 312 is connected to the outside through a ventilation hole 321. The fan 2 is disposed in the rear chamber 312. Along the airflow direction, the cross-sectional area of ​​the front chamber 311 gradually increases. Specifically, the lower shell of the mounting shell 33 is a flat plate structure, and the shape of the upper shell of the mounting shell 33 can be set according to actual needs, as long as the flow area of ​​the front chamber 311 gradually increases. In this embodiment, the cross-sectional area of ​​the front chamber 311 gradually increases, thereby forming a gradually expanding airflow guiding structure. The cross-sectional area of ​​the rear chamber 312 remains unchanged and is the same as the maximum cross-sectional area of ​​the front chamber 311. Therefore, air can enter the rear chamber 312 under the guidance of the front chamber 311, and the fan 2 in the rear chamber 312 can fully contact the incoming air, which can effectively avoid airflow disturbance inside the accommodating cavity 31, thereby maximizing the driving efficiency of the fan 2. Understandably, the overall airflow path in the mat is: air inlet - circulation channel - air outlet - inlet - front chamber 311 - rear chamber 312 - fan 2 - ventilation hole 312 - outside.

[0043] To ensure the installation stability of fan 2, such as Figure 3 and Figure 4 As shown, a connecting rib 34 is provided in the rear chamber 312. The connecting rib 34 is fixedly connected to the air outlet assembly 3 and surrounds the fan 2. The fan 2 is sealed to the connecting rib 34. Specifically, the connecting rib 34 is arranged around the fan 2 in the rear chamber 312. The connecting rib 34 is integrally formed with the mounting shell 33. The outer shell of the fan blades on the fan 2 abuts against the surrounding connecting rib 34 and is connected by sealant. This ensures the reliability of the connection between the fan 2 and the mounting shell 33, and also effectively prevents air leakage from the joint between the two, which would reduce the airflow.

[0044] like Figure 1 As shown, the length of the air inlet is not less than half the width of the pad 1, and the air inlet is symmetrically arranged with respect to the first axis. The first axis is the axis of symmetry of the pad 1 along the width direction. Since the length of the air inlet is not less than half the width of the pad 1, this design is conducive to increasing the airflow. At the same time, since the air inlet is symmetrically arranged with respect to the first axis, it can ensure that there is a uniform airflow on both sides of the pad 1 along the length direction, so as to ensure a uniform and stable heat dissipation effect on the surface of the pad 1.

[0045] like Figure 1As shown, multiple air outlets are provided, which are symmetrically arranged on both sides of the tail end 12 relative to the first axis. Because the air outlets are symmetrically arranged relative to the first axis, the air inside the pad 1 can flow out evenly from both sides of the tail end 12, thereby ensuring a uniform and stable cooling effect near the tail end 12. The symmetrically arranged air outlets cooperate with the symmetrically arranged air inlets, so that the air flows in evenly and stably from the head end 11, passes through the human torso, and then flows out evenly from the air outlets on both sides, improving the uniformity of air flow inside the pad 1 and avoiding uneven heat dissipation on the surface of the pad 1, thereby further improving the user comfort.

[0046] To prevent external debris from entering the interior of pad 1, such as... Figure 1 and Figure 5 As shown, a filter 111 is installed at the air inlet. The filter 111 can block external debris and prevent it from being sucked into the flow channel inside the pad 1, thus affecting the airflow effect.

[0047] like Figure 1 and Figure 5 As shown, the mat also includes a control unit 4, which includes a controller 41 and a control line 42. The controller 41 is electrically connected to the fan 2 via the control line 42. At least part of the control line 42 is located inside the mat body 1. The controller 41 is used to output electrical signals. Specifically, the fan 2 is connected to an external power source. The remote control 41 can send electrical signals to the fan 2 via the control line 42 to control the start and stop of the fan 2. The remote control 41 is located near the head end 11 for easy operation by the user. It can be understood that in addition to controlling the start and stop of the fan 2, the controller 41 also has a multi-level wind speed adjustment function to adjust the ventilation volume according to the user's needs.

[0048] Furthermore, such as Figure 5 As shown, an elastic strap 13 is provided inside the pad 1, and the control line 42, which is located inside the pad 1, is limited and passes through the elastic strap 13. Specifically, most of the control line 42 is embedded inside the pad 1 and fixed by the elastic strap 13 inside the pad 1. For easy viewing, the elastic strap 13 embedded inside the pad 1 and part of the control line 42 are drawn. The elastic strap 13 allows the control line 42 to be pulled within a certain range, which enhances the flexibility of the control unit 4 while ensuring its reliability. The control line 42 embedded inside the pad 1 is set along the edge of the pad 1 to reduce the impact on the flow channel and facilitate later maintenance.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
