Description

[Technical Field]

[0001] This application relates to the field of smart home technology, and in particular to a smart temperature-controlled seat cushion. [Background Technology]

[0002] Seat cushions are generally office and home products designed to improve user comfort. They provide cushioning for office workers who sit for long periods or need to maintain a seated posture for extended periods, and are primarily used to cushion seats, benches, or other platforms that can be used for sitting.

[0003] In existing technologies, the primary function of seat cushions is to provide a soft pad, and a wide variety of structures are already available on the market. However, current seat cushions cannot directly regulate temperature. Prolonged sitting can easily lead to excessively high buttock temperatures, causing discomfort; or, in cold weather, the seat cushion may be too cold to sit on directly. Furthermore, to achieve even temperature control in seat cushions, heat-conducting liquids are typically used, but with prolonged use, issues such as evaporation and loss of the internally stored liquid can occur. [Utility Model Content]

[0004] This application provides a smart temperature-controlled seat cushion that solves the above-mentioned problems.

[0005] This application provides an intelligent temperature-controlled seat cushion comprising a shell, a circulating liquid bag, a liquid storage tank, and a temperature-controlled circulation device.

The temperature-controlled circulation device and the liquid storage tank are both housed within the shell. The circulating liquid bag is connected to the liquid storage tank and the temperature-controlled circulation device via a water pipe. The temperature-controlled circulation device is used to drive the circulating liquid to circulate among the liquid storage tank, the circulating liquid bag, and the temperature-controlled circulation device, and to control the temperature of the circulating liquid. The liquid storage tank includes a first cover and a second cover. The body has a first cover with an injection port and a first locking groove; a liquid-containing space is formed between the first cover and the second cover; the second cover has a separation strip and a second liquid inlet and a second liquid outlet; the separation strip is located on the second cover near the second liquid inlet and the second liquid outlet, dividing the liquid-containing space into a flow chamber and a storage chamber; a flow port is provided between the flow chamber and the storage chamber, and the flow chamber is connected through the flow port; the second liquid inlet and the second liquid outlet are both located on one side of the flow chamber and are used to install the water pipe.

[0007] Specifically, the distal end is spaced apart from the other side wall to form the flow port; or the distal end is connected to any one of the first side wall, the second side wall, the third side wall, or the fourth side wall, and the flow port is opened on the isolation strip.

[0008] Specifically, the second cover also includes a force-bearing part and a sliding groove. The force-bearing part is located on the first bottom wall of the second cover. The sliding groove is located on the surface of the second side wall and the third side wall facing the housing. The housing is provided with a slide rail corresponding to the sliding groove.

[0009] Specifically, the temperature control circulation device includes a power supply, a heat exchange module, a pump, a fan, and a controller. The pump and the heat exchange module are connected to the circulating liquid bag and the storage tank via water pipes. The fan is positioned relative to the heat exchange module. The controller is electrically connected to the power supply, the heat exchange module, the pump, and the fan. The pump drives the circulating liquid to circulate between the heat exchange module, the circulating liquid bag, the storage tank, and the pump. The heat exchange module controls the temperature of the circulating liquid. The fan removes the heat generated by the heat exchange module during operation, controlling the temperature inside the housing. The heat exchange module includes a heat exchange component, a heat pipe, and a heat sink. The controller is electrically connected to the heat exchange component and controls the heat exchange component to switch between cooling and heating modes. The heat pipe passes through the heat exchange component and exchanges heat with it. The heat sink is connected to the heat exchange component via the heat pipe and absorbs the heat transferred from the heat exchange component by the heat pipe. The fan is located at one end of the heat sink.

[0010] Specifically, the heat exchange assembly includes a cooling plate, a heat spreader plate, and a water-cooled exchange plate, with the heat pipe passing through the heat spreader plate; the cooling plate is sandwiched between the heat spreader plate and the water-cooled exchange plate, and the water-cooled exchange plate is connected to the water pipe and has an exchange channel for the circulation liquid to flow.

[0011] Specifically, there are two heat sinks and two fans, respectively located on both sides of the controller; the housing also has a first air inlet, a first air outlet, a second air inlet, and a second air outlet; and has a first protruding edge, a second protruding edge, a third protruding edge opposite to the first protruding edge, and a fourth protruding edge opposite to the second protruding edge; wherein, the first protruding edge and the third protruding edge cooperate to form a first heat dissipation air duct by combining the first air inlet, the first air outlet, and the location of the fan and the heat sink on one side, the first heat dissipation air duct draws in air from the first air inlet, passes through the fan and the heat sink, and is discharged from the first air outlet; the second protruding edge and the fourth protruding edge cooperate to form a second heat dissipation air duct by combining the second air inlet, the second air outlet, and the location of the fan and the heat sink on the other side.

The ventilation opening is obliquely arranged from the position of the second mounting groove along the flow direction of the airflow in the first heat dissipation duct. The ventilation opening and the position of the controller form the third heat dissipation duct.

[0014] Specifically, the power supply is connected to a cable, one end of which is connected to the power supply, and the other end extends outward from inside the housing for charging the power supply.

Detailed Implementation Methods

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0038] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.

[0039] Please also refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A smart temperature-controlled seat cushion 100 includes a housing 1, a temperature-controlled circulation device 3, a liquid storage tank 5, a circulating liquid bag 7, and a seat cover 9. The temperature-controlled circulation device 3 and the liquid storage tank 5 are both housed within the housing 1. The circulating liquid bag 7 is connected to the liquid storage tank 5 and the temperature-controlled circulation device 3 via a water pipe 2. The temperature-controlled circulation device 3 drives the circulating liquid 4 to circulate among the liquid storage tank 5, the circulating liquid bag 7, and the temperature-controlled circulation device 3, and controls the temperature of the circulating liquid 4.

[0040] The circulating fluid bag 7 is located on one side of the housing 1. The seat cover 9 covers the circulating fluid bag 7, or the housing 1 and the circulating fluid bag 7 are covered together, or the bag is embedded in the housing 1 and cooperates with the housing 1 to cover the circulating fluid bag 7. The intelligent temperature-controlled seat cushion 100 can be placed on a chair, bench, or other platform for sitting, with the circulating fluid bag 7 facing the side for the user to sit on, so that the user can intelligently control the temperature of the seat where their buttocks contact the seat as needed when working or resting.

[0041] Of course, a soft pad 91 can also be sandwiched between the circulating fluid bag 7 and the shell 1 to further increase user comfort. The shape and size of the soft pad 91 are correspondingly set to the shell 1, and the specific thickness is set as needed and is not limited here. The seat cover 9 can adopt a peripheral elastic design or a zipper design to cover other parts. This design method mainly facilitates the disassembly and assembly of the seat cover 9, allowing users to disassemble, wash and reuse the seat cover 9, or choose patterns and breathable textures according to personal preferences; at the same time, it can also be used to relatively fix the position of the circulating fluid bag 7 and the soft pad 9.

[0042] The temperature control circulation device 3 includes a controller 31, a power supply 33, a pump 35, a heat exchange module 37, a fan 38, and a switch button 39. The controller 31 is electrically connected to the power supply 33, the pump 35, the heat exchange module 37, the fan 38, and the switch button 39 via a cable 6. The power supply 33 can be configured as a rechargeable power supply for multiple cycles to provide electrical energy. The intelligent temperature control seat cushion 100 is not only reusable but also easy to carry.

[0043] The pump 35, the heat exchange module 37, the circulating liquid bag 7, and the storage tank 5 are connected via the water pipe 2. In this embodiment, the connection sequence is: storage tank 5, pump 35, heat exchange module 37, circulating liquid bag 7, and then back to storage tank 5. The controller 31 uses the pump 35 to achieve sequential circulation of the circulating liquid 4 and uses the heat exchange module 37 to control the temperature of the circulating liquid 4.

[0044] Of course, in another embodiment, the connection positions of the pump 35 and the heat exchange module 37 can be interchanged. That is, the connection sequence can also be the liquid storage tank 5, the heat exchange module 37, the pump 35, the circulating liquid bag 7, and then back to the liquid storage tank 5. The controller 31 realizes the sequential circulation of the circulating liquid 4 through the pump 35 and realizes the temperature control of the circulating liquid 4 through the heat exchange module 37.

[0045] Please continue reading. Figure 6 and Figure 7 The fan 38 is positioned close to the heat exchange module 37 and works in conjunction with the heat exchange module 37 to dissipate the heat released by the heat exchange module 37 during operation. The heat exchange module 37 includes a heat exchange component 371, a heat pipe 373, and a heat sink 375.

[0046] The heat exchange assembly 371 includes a cooling element 3711, a heat spreader 3713, and a water-cooled heat exchanger 3715. The cooling element 3711 is sandwiched between the heat spreader 3713 and the water-cooled heat exchanger 3715. The heat pipe 373 passes through the heat spreader 3713 and is in full contact with it. The water-cooled heat exchanger 3715 is connected to the water pipe 2. The circulating liquid 4 flows through the water-cooled heat exchanger 3715, making full contact with the cooling element 3711 and exchanging heat. The cooling element 3711 is electrically connected to the controller 31 and is controlled by the controller 31 to switch between cooling mode and heating mode.

[0047] The cooling chip 3711 can be an existing TEC semiconductor cooling chip 3711 or a structure with the same function. The controller 31 controls the working state of the heat exchange assembly 371 to achieve the function of cooling on one side and heating on the other side. Moreover, by adjusting the electrodes on both sides of the cooling chip 3711, the cooling and heating surfaces can be changed, and the cooling mode and heating mode can be switched without moving the cooling chip 3711. The heat spreader 3713 and the water-cooled exchange plate 3715 are both made of aluminum blocks. The water-cooled exchange plate 3715 has an exchange channel 3701 facing the cooling chip 3711 or has an internal exchange channel 3701 for the circulation liquid 4 to flow. The exchange channel can be a multi-bend channel or multiple straight channels to ensure that the circulation liquid 4 and the cooling chip 3711 or the cooling chip 3711 through the water-cooled exchange plate 3715 have sufficient heat exchange.

[0048] The heat exchange plate 3713 fully exchanges heat with the other side of the cooling plate 3711, and transfers the temperature to the heat sink 375 through the heat pipe. The fan 38 is located at one end of the heat sink 375 and dissipates the heat transferred to the heat sink 375.

[0049] The heat pipe 373 includes a hollow pipe wall 3731 and a heat transfer medium (not shown). The heat transfer medium is disposed within the pipe wall 3731, which is divided into an evaporation section 3733 and a condensation section 3735. The evaporation section 3733 is the area near the heat spreader 3713, and the condensation section 3735 is the area near the heat sink 375. The heat transfer medium is a two-phase gas-liquid medium, characterized by easy vaporization when heated and easy liquefaction when cooled. In the evaporation section 3733, the heat transfer medium absorbs heat transferred from the heat spreader 3713, changing from a liquid to a gaseous state. Under the action of a pressure difference within the pipe wall 3731, the gaseous heat transfer medium flows to the condensation section 3735, contacts the heat sink 375, releases heat, and recondenses from a gaseous state back into a liquid state. The specific selection of the heat transfer medium is not limited here.

[0050] The heat sink 375 is made of aluminum alloy, brass, or bronze in a plate, sheet, or multi-sheet structure. The pipe wall 3731 is made of a thermally conductive metal (such as copper, aluminum, etc.), graphite, or existing thermally conductive composite material; the specific material is not limited here. The heat sink 375 is connected to the heat exchange assembly 371 through the heat pipe 373, absorbing the heat transferred from the heat exchange assembly 371 by the heat pipe 373, and providing installation space for the water pipe 2 connecting the heat exchange assembly 371 to the liquid storage tank 5 and the pump 35, and facilitating the establishment of a heat dissipation channel by the heat sink 375.

[0051] Since the intelligent temperature-controlled seat cushion 100 is intended to be placed on a platform such as a seat or bench for user use, its vertical height is subject to certain requirements; the height of the housing 1 cannot be too high. The heat exchange component 371, the heat pipe 373, the heat sink 375, and the fan 38 are all located on the same plane to ensure smooth heat transfer while minimizing the height of the housing 1 for user convenience. In this embodiment, this arrangement allows the heat sink 375 to be positioned horizontally, reducing the height of the housing 1. Furthermore, the heat sink 375 does not need to be stacked directly on top of the heat exchange component 371, further limiting the height of the housing 1.

[0052] To enhance heat dissipation, in this embodiment, the heat exchange module 37 includes two heat sinks 375, which are spaced apart on both sides of the heat exchange assembly 371. A heat pipe 373 penetrates the heat exchange assembly 371, with its two ends connected to the two spaced-apart heat sinks 375. In this configuration, the evaporation section 3733 is located in the middle section of the pipe wall 3731, while the condensation section 3735 is located at both ends of the pipe wall 3731. This creates a dual-circulation heat transfer path for the heat transfer medium within the pipe wall 3731, thereby improving heat dissipation efficiency.

[0053] Correspondingly, the number of fans 38 corresponds one-to-one with the number of heat sinks 375, and they are respectively positioned close to the heat sinks 375. To limit the height of the housing 1, the fans 38 are vortex fans, which, unlike traditional fans, have an airflow direction perpendicular to the plane where the blades are mounted and rotate. The airflow direction of the vortex fan is coplanar with the plane where the blades are mounted and rotate, so that the fans 38 and the heat sinks 375 are horizontally attached to the same plane of the housing 1 at intervals. When the fans 38 are in operation, they can draw in cool air from outside the housing 1 and blow it out from the side toward the heat sinks 375.

[0054] It should be noted that the number of heat exchange components 371, heat pipes 373, and heat sinks 375 in the heat exchange module 37 is not limited, and similarly, the number of fans 38 is not limited and can be set according to the heat dissipation requirements. In this embodiment, the heat sinks 375 and fans 38 are preferably two in number and symmetrically arranged on both sides of the heat exchange components 371. This arrangement not only makes the most rational use of the internal space of the housing 1, but also ensures the highest heat dissipation efficiency and prevents airflow interference and disorder within the housing 1, thus avoiding uncontrollable internal temperature. The issue of heat dissipation efficiency will be discussed in more detail below.

[0055] Please see Figure 8 and Figure 9 The liquid storage tank 5 is used to store the circulating liquid 4 and participates in the temperature control cycle. Since the intelligent temperature-controlled seat cushion 100 will experience evaporation and loss of the circulating liquid 4 with prolonged use, the liquid storage tank 5 can continuously supply the circulating liquid 4. The liquid storage tank 5 includes a first cover 51 and a second cover 53, forming a liquid-containing space 501 between the first cover 51 and the second cover 53 to contain the circulating liquid 4.

[0056] The first cover 51 has a liquid injection port 5101 and a first engaging groove 511. The liquid injection port 5101 facilitates the addition of the circulating liquid 4 by the user. The first engaging groove 511 is used to engage with the housing 1 to limit the position of the first cover 51. The second cover 53 includes a first bottom wall 531 and four side walls. The four side walls include a first side wall 532 facing the heat exchange module 37, a second side wall 533 and a third side wall 534 symmetrically arranged on both sides of the first bottom wall 531, and a fourth side wall 535 opposite to the first side wall 532. The second cover 53 also has a second liquid inlet 5301, a second liquid outlet 5303, a separating strip 536, a force-bearing part 537, a sliding groove 538, and a second engaging groove 539. The second liquid inlet 5301 and the second liquid outlet 5303 are spaced apart on the first side wall 532 for installing the water pipe 2, so that the circulating liquid 4 stored in the liquid storage space 501 enters the temperature-controlled circulation process.

[0057] The isolation strip 536 is positioned on the second cover 53 near the second liquid inlet 5301 and the second liquid outlet 5303, and protrudes from the first bottom wall 531 toward the first cover 51 and abuts against the first cover 51. The isolation strip 536 divides the liquid-containing space 501 into two parts: a smaller flow cavity 5011 and a relatively larger storage cavity 5013. A flow port 5305 is provided between the flow cavity 5011 and the storage cavity 5013, and the two parts are connected through the flow port 5305. The second liquid inlet 5301 and the second liquid outlet 5303 are both located on one side of the flow cavity 5011.

[0058] The isolation strip 536 can be L-shaped, I-shaped, or other shapes, simply to physically divide the liquid-containing space 501 into two parts. The isolation strip 536 can include a proximal end 5361 and a distal end 5363. The proximal end 5361 can be connected to any one of the first sidewall 532, the second sidewall 533, the third sidewall 534, or the fourth sidewall 535 of the second cover 53. That is, the proximal end 5361 can abut against the first sidewall 532 where the second liquid inlet 5301 and the second liquid outlet 5303 are located, or it can abut against the second sidewall 533 or other sidewalls to form a sealing effect. The distal end 5363 forms the flow port 5305 opposite to the other sidewall (the distal end can be connected to the sidewall, but a flow port is opened, and the position of the flow port is not limited). In this embodiment, the proximal end 5361 abuts against the first sidewall 532, and the distal end 5363 is spaced apart from the third sidewall 534 of the second cover 53, forming the flow port 5305 with the third sidewall 534.

[0059] Of course, in another embodiment, the distal end 5363 and the proximal end 5361 can directly abut against either sidewall, and the flow port 5305 can be directly opened on the isolation strip 536 to achieve isolation while opening the flow port.

[0060] This configuration ensures that a portion of the circulating liquid 4 located in the flow chamber 5011 of the liquid storage tank 5 participates in temperature change control and circulation, while the circulating liquid 4 stored in the liquid storage chamber 5013 does not directly participate in circulation, thereby reducing energy loss during the operation of the heat exchange module 37. As the number of uses of the intelligent temperature-controlled cushion 100 increases, after the circulating liquid 4 evaporates, the circulating liquid 4 stored in the liquid storage chamber 5013 can be automatically replenished into the flow chamber 5011 through the flow port 5305, thus entering circulation. This internal automatic replenishment method ensures that the intelligent temperature-controlled cushion 100 will not cause the heat exchange module 37 and the pump 35 to run dry due to a lack of circulating liquid 4, nor will it cause a large number of air bubbles to appear in the circulating liquid bag 7.

[0061] The force-receiving part 537 is provided on the first bottom wall 531 of the second cover 53, facilitating manual pushing and pulling of the liquid storage tank 5 by the user. In this embodiment, the force-receiving part 537 has a concave structure, recessed into the liquid storage cavity 5013 from the second cover 53 toward the first cover 51. The sliding groove 538 and the second engaging groove 539 are provided on the second sidewall 533 and the third sidewall 534 on both sides of the second cover 53, facing the housing 1. The sliding groove 538 is used for the liquid storage tank 5 to slide relative to the housing 1, and the second engaging groove 539 cooperates with the housing 1 to further define the position of the liquid storage tank 5. The force-receiving part 537 and the sliding groove 538 are mainly used to cooperate with the housing 1, allowing the user to push and pull the liquid storage tank 5 through the force-receiving part 537, and the liquid storage tank 5 moves relative to the housing 1 along the direction of the sliding groove 538.

[0062] It should be noted that the sliding groove 538 and the second engaging groove 539 can be spaced apart or share the same groove. The specific arrangement and method correspond to the housing 1, which will be discussed further below and are not limited here. The force-bearing part 537 can also be a raised friction surface, and it protrudes from the second cover 53 toward the housing 1.

[0063] The liquid storage tank 5 and the housing 1 are integrally designed like a drawer, allowing the liquid storage tank 5 to be pulled out of the housing 1 when the circulating liquid 4 in the tank is insufficient, and the circulating liquid 4 can be replenished through the injection port 5101. When the liquid storage tank 5 is installed in a preset position on the housing 1, the first engaging groove 511 and the second engaging groove 539 correspond to the engaging structure on the housing 1, achieving an engaging connection between the liquid storage tank 5 and the housing 1, limiting the position of the liquid storage tank 5 and preventing it from sliding out of the housing 1. It should be noted that the first engaging groove 511 and the second engaging groove 539 can exist individually or simultaneously, and their specific positions and quantities are not further limited here.

[0064] Please continue to refer to the following: Figure 10 , Figure 11 and Figure 12 The housing 1 includes an upper cover 11 and a lower cover 13. The upper cover 11 and the lower cover 13 cooperate to form a receiving space 101, and the temperature control circulation device 3 is disposed in the receiving space 101. The upper cover 11 and the lower cover 13 can be connected by snap-fitting or fixing by connectors.

[0065] The upper cover 11 includes a supporting plane 111 and a supporting inclined surface 113. The supporting plane 111 and the supporting inclined surface 113 are set at a certain preset angle, that is, the supporting plane 111 and the supporting inclined surface 113 are not coplanar or parallel. The specific angle is related to the height of the lower cover 13. The supporting plane 111 in the upper cover 11 has a first liquid inlet 1101 and a first liquid outlet 1103 near the liquid storage tank 5. The circulating liquid bag 7 is located on one side of the upper cover 11, and is connected to the heat exchange module 37 through the first liquid inlet 1101 via a water pipe 2, and is connected to the liquid storage tank 5 through the first liquid outlet 1103 via a water pipe 2. The first liquid inlet 1101 and the first liquid outlet 1103 are set relatively close to the liquid storage tank 5, which can reduce the connection length of the water pipe 2 between the liquid storage tank 5 and the circulating liquid bag 7, reduce the temperature loss of the circulating liquid 4, and avoid interference with other parts, making full use of space.

[0066] Of course, the first liquid inlet 1101 and the first liquid outlet 1103 are only functional divisions. They can be two separate parts or a common channel, both used for the passage of the water pipe 2. There is no limitation here.

[0067] In addition, the support plane 111 may also have a notch 1105 near the liquid storage tank 5. The notch 1105 is close to the first liquid inlet 1101 and the first liquid outlet 1103, and corresponds to the first cover 51 of the liquid storage tank 5. The size of the notch is set relative to the first cover 51 to facilitate the sliding installation of the liquid storage tank 5 relative to the shell 1.

[0068] Please refer to the following: Figure 13 , Figure 14 , Figure 15 and Figure 16 The lower cover 13 includes a second bottom wall 131 and three supporting side walls 133. The supporting plane 111 abuts against the three supporting side walls 133 respectively, and the supporting inclined surface 113 abuts against the second bottom wall 131 and two symmetrically arranged supporting side walls 133 respectively. This arrangement makes the shell 1 have a trapezoidal shape, which is ergonomic. When the user sits down, the area near the legs tends to slide down, increasing comfort.

[0069] In this embodiment, the lower cover 13 is provided with a first mounting groove 1311, a second mounting groove 1313, a third mounting groove 1315, a fourth mounting groove 1317 and a fifth mounting groove 1318 at intervals, for mounting the liquid storage tank 5, the heat exchange module 37, the controller 31, the fan 38, the power supply 33 and the pump 35 in the temperature control circulation device 3.

[0070] The first mounting groove 1311 is located on the side away from the supporting inclined surface 113, and is recessed from the lower cover 13 toward the upper cover 11 for mounting the liquid storage tank 5. The first mounting groove 1311 includes a sliding surface 13111 slidably connected to the first cover 51, a slide rail 13113 slidably connected to the sliding groove 538, a through hole 13101 connected to the second liquid inlet 5301 and the second liquid outlet 5303, and a first elastic protrusion 13115 and a second elastic protrusion 13117 engaged with the first engaging groove 511 and the second engaging groove 539.

[0071] The first elastic protrusion 13115 is disposed on the sliding surface 13111, and the second elastic protrusion 13117 and the slide rail 13113 are disposed on both sides of the first mounting groove 1311. After the upper cover 11 and the lower cover 13 are installed in contact, the sliding surface 13111 and the notch 1105 are matched in position. The liquid storage tank 5 is slidably connected to the housing 1 along the sliding surface 13111 and the slide rail 13113, and is installed in the first mounting groove 1311. After the liquid storage tank 5 is installed into the preset position of the first mounting groove 1311, the first elastic protrusion 13115 engages with the first engaging groove 511, fixing the position of the liquid storage tank 5 relative to the housing 1, so that the liquid storage tank 5 will not be displaced by the shaking or movement of the housing 1.

[0072] When the circulating liquid 2 needs to be added, the user pulls the storage tank 5 relative to the housing 1 using the force-bearing part 537. During the movement, when the storage tank 5 moves away from the first mounting groove 1311 by a certain position, the second elastic protrusion 13117 engages with the second engaging groove 539 to limit its movement. The arrangement of the second elastic protrusion 13117 and the second engaging groove 539 prevents the storage tank 5 from being directly removed from the housing 1, protecting the water pipe 4 connected to the storage tank 5.

[0073] It should be noted that the slide rail 13113 and the second elastic protrusion 13117 can be spaced apart on the same height plane or spaced apart on different height planes. Correspondingly, the sliding groove 538 and the second engaging groove 539 share a groove or are spaced apart. For example, when the slide rail 13113 and the second elastic protrusion 13117 are located at the same height plane, the sliding groove 538 and the second engaging groove 539 directly share a groove. Of course, in this embodiment, the sliding groove 538 and the second engaging groove 539 are spaced apart, and the slide rail 13113 and the second elastic protrusion 13117 are spaced apart on different height planes, so they will not interfere with each other.

[0074] The user pushes and pulls the liquid storage tank 5 using the force-bearing part 537. The sliding groove 538 slides against the slide rail 13113. When the liquid storage tank 5 is fully installed in the first mounting groove 1311, the second liquid outlet 5303 is opposite to the through hole 13101, facilitating the entry of the water pipe 2 from the second liquid outlet 5303. The first elastic protrusion 13115 engages with the first engaging groove 511, and two second elastic protrusions 13117 engage with the second engaging grooves 539 on both sides of the liquid storage tank 5, thereby helping to fix the position of the liquid storage tank 5.

[0075] The second mounting slot 1313 and the third mounting slot 1315 are sequentially arranged close to the first mounting slot 1311 and are both located on the same plane. The heat exchange module 37 and the fan 38 are installed in the second mounting slot 1313, and the controller 31 is installed in the third mounting slot 1315. In this embodiment, the second mounting slot 1313 is U-shaped and surrounds the first mounting slot 1311, and includes a first mounting part 13131, two second mounting parts 13133, and two third mounting parts 13135.

[0076] The heat exchange component 371 is disposed in the first mounting part 13131, located between the first mounting groove 1311 and the third mounting groove 1315, and is disposed close to the through hole 13101, so that the water pipe 2 can enter the heat exchange component 371, reducing the length of the water pipe 2 and reducing the temperature loss of the circulating liquid 4.

[0077] The heat sink 375 is disposed on the second mounting part 13133. In order to increase the heat dissipation effect, in this embodiment, two heat sinks 375 are respectively disposed on two second mounting parts 13133. The two second mounting parts 13133 are spaced apart on both sides of the first mounting part 13131 and are flush with the first mounting part 13131, which facilitates the installation of the heat pipe 373.

[0078] The fan 38 is disposed on the third mounting part 13135, which is sandwiched between the second mounting part 13133 and the housing 1, and is located near the first mounting groove 1311. In this embodiment, two fans 38 are provided, respectively disposed on two third mounting parts 13135, and spaced apart on both sides of the first mounting groove 1311, close to the edge of the housing 1. This arrangement ensures that the liquid storage tank 5, the heat exchange module 37, and the controller 31 are all located on the same plane and below the support plane 111, minimizing the height of the housing 1. Furthermore, this arrangement not only considers the convenience of connecting the water pipe 2, but also provides a better solution for heat dissipation. By simply setting an air inlet on the housing 1 near the fan 38, cool air from outside the housing 1 can be provided towards the heat sink 375.

[0079] Please continue to refer to the following: Figure 17 and Figure 18To ensure effective heat dissipation, the housing 1 is provided with a first air inlet 1301, a first air outlet 1303, a second air inlet 1305, and a second air outlet 1307. Inside the housing 1, a first heat dissipation duct 1302, a second heat dissipation duct 1304, and a third heat dissipation duct 1306 are provided opposite to the second mounting groove 1313 and the third mounting groove 1315. The third mounting groove 1315 has a first protruding edge 13151 and a second protruding edge 13153 on both sides, and a third protruding edge 13155 and a fourth protruding edge 13157 are respectively provided opposite to the first and second protruding edges 13151 and 13153. The first protruding edge 13151 and the third protruding edge 13155 cooperate to form a first heat dissipation air duct 1302 by combining the positions of the first air inlet 1301, the first air outlet 1303, the fan 38 and the heat sink 375. The first heat dissipation air duct 1302 draws in air from the first air inlet 1301, passes through the fan 38 and the heat sink 375, and is discharged from the first air outlet 1303. The second protruding edge 13153 and the fourth protruding edge 13157 cooperate to form a second heat dissipation air duct 1304 by combining the positions of the second air inlet 1305, the second air outlet 1307, the fan 38 and the heat sink 375 on the other side.

[0080] The first protruding edge 13151, the second protruding edge 13153, the third protruding edge 13155, and the fourth protruding edge 13157 all extend upward from the lower cover 13 and abut against the upper cover 11. In this embodiment, the first air outlet 1303 and the second air outlet 1307 are symmetrically arranged on both sides of the lower cover 13; correspondingly, the first protruding edge 13151, the second protruding edge 13153, the third protruding edge 13155, and the fourth protruding edge 13157 are arranged in an "L" shape, and the first protruding edge 13151 and the third protruding edge 13155 bend in the same direction, and the second protruding edge 13153 and the fourth protruding edge 13157 bend in the same direction. That is to say, the first heat dissipation duct 1302 and the second heat dissipation duct 1304 are also arranged in an "L" shape symmetrically.

[0081] Because the support ramp 113 needs to be ergonomically designed to increase user comfort, the height of the housing 1 near the support ramp 113 is relatively low. Therefore, the intelligent temperature-controlled seat cushion 100 uses the above-mentioned design to plan the first heat dissipation duct 1302 and the second heat dissipation duct 1304, ensuring a large channel space and improving heat dissipation efficiency. Furthermore, the protruding edges on both sides of each duct prevent airflow turbulence inside the housing 1, improving heat dissipation efficiency while ensuring the safe operation of the controller 31, the power supply 33, and the pump 35.

[0082] It should be noted that the first protruding edge 13151, the second protruding edge 13153, the third protruding edge 13155, and the fourth protruding edge 13157 can also be configured with other shapes or sizes, without further restrictions. It is only necessary to ensure that the first heat dissipation duct 1302 and the second heat dissipation duct 1304 can pass through the first air inlet 1301 (second air inlet 1305), the fan 38, the heat sink 375, and the first air outlet 1303 (second air outlet 1307). Furthermore, the relative spacing between the first air inlet 1301 and the first air outlet 1303, and between the second air inlet 1305 and the second air outlet 1307, is not specifically limited. To ensure that the air intake and exhaust do not interfere with each other, they can be positioned as far apart as possible. Therefore, the arrangement of the first heat dissipation duct 1302 and the second heat dissipation duct 1304 is related to the positions of the first air inlet 1301, the first air outlet 1303, the second air inlet 1305, and the second air outlet 1307. For example, the whole structure can be configured as a curved quarter-circle arc structure or a "U"-shaped structure; or, for example, the first protruding edge 13151, the second protruding edge 13153, the third protruding edge 13155, and the fourth protruding edge 13157 can be configured as a multi-shaped structure, so that a multi-shaped heat dissipation channel structure is formed inside.

[0083] The third heat dissipation duct 1306 is mainly used for heat dissipation of the controller 31 and can cooperate with the first heat dissipation duct 1302 or the second heat dissipation duct 1304. In this embodiment, at least one vent 1309 is provided near the controller 31 on the first protruding edge 13151, and at least one vent 1309 forms the third heat dissipation duct 1306 with the second mounting groove 1313. Under the action of the fan 38, the first heat dissipation duct 1302 forms airflow. Affected by the airflow, a certain negative pressure is formed at the vent 1309. The heat dissipated by the controller 31 at the second mounting groove 1313 is affected by the negative pressure and discharged into the first heat dissipation duct 1302 through the vent 1309, and finally discharged to the outside of the housing 1 through the first air outlet 1303. The arrangement of at least one vent 1309 is simple in structure and can achieve heat dissipation of the controller 31 without occupying additional space inside the housing 1.

[0084] Please refer to the following: Figure 19To improve the heat dissipation efficiency of the controller 31, the vent 1309 is designed at an angle, and is obliquely positioned from the position of the second mounting groove 1313 along the airflow direction in the first heat dissipation duct 1302. The tilt angle θ is set between 30° and 90°, and the tilt angle θ is the angle between the airflow direction through the vent 1309 and the airflow direction in the first heat dissipation duct 1302. The setting of the tilt angle θ ensures that the third heat dissipation duct 1306 has sufficient negative pressure, while also preventing it from interfering with the airflow in the first heat dissipation duct 1302, effectively improving the overall heat dissipation effect.

[0085] Furthermore, at least one ventilation opening 1309 can also be provided on the second protruding edge 13153 near the controller 31, so that the ventilation opening 1309 and the second mounting groove 1313 form two third heat dissipation air channels 1306. The heat dissipated by the controller 31 can enter the first heat dissipation air channel 1302 and the second heat dissipation air channel 1304 through the third heat dissipation air channels 1306. The specific principle is described above and will not be repeated here. That is to say, the first protruding edge 13151 and / or the second protruding edge 13153 are provided with the ventilation opening 1309, thereby forming the third heat dissipation air channel 1306 for heat dissipation of the controller 31.

[0086] In this embodiment, the fourth mounting slot 1317 and the fifth mounting slot 1318 are spaced apart on the side of the lower cover 13 near the supporting inclined surface 113. The fourth mounting slot 1317, adjacent to the third mounting slot 1315, is used to install the power supply 33, facilitating electrical connection between the power supply 33 and the controller 31, shortening the cable 6 length, and keeping it away from the liquid storage tank 5 to ensure circuit safety. The fifth mounting slot 1318, located on the side of the fourth mounting slot 1317 near the second heat dissipation duct 1304, is used to install the pump 35. The power supply 33 and the pump 35 are horizontally positioned between the lower cover 13 and the upper cover 11, with a low overall height, and are located near the supporting inclined surface 113, making full use of the internal space of the housing 1.

[0087] In this embodiment, to prevent the circulating liquid 4 from seeping into the controller 31, a fifth protruding edge 13159 is provided on the side of the second protruding edge 13153 near the controller 31. The second protruding edge 13153 and the fifth protruding edge 13159 cooperate to form a water pipe channel 13103. The water pipe channel 13103 passes through the second mounting groove 1313 and the fifth mounting groove 1318, and is used to accommodate the water pipe 2 connecting the pump 35, the heat exchange assembly 371, and the liquid storage tank 5. This ensures that the circulating liquid 4 is separated from the controller 31 when flowing in the water pipe 2, and the water pipe channel 13103 has a small space, only used to store the water pipe 2, which can effectively restrict the position of the water pipe 2.

[0088] Of course, in another embodiment, the fifth mounting slot 1318 can be positioned on the side of the fourth mounting slot 1317 adjacent to the first heat dissipation duct 1302. Correspondingly, a fifth protruding edge 13159 needs to be provided on the side of the first protruding edge 13151 near the controller 31. Furthermore, the third heat dissipation duct 1306 needs to be replaced to a position that mates with the second heat dissipation duct 1304, and the vent 1309 is located on the second protruding edge 13153. In other words, the arrangement of the pump 35 not only needs to consider making the most of the space inside the housing 1, but also needs to ensure that the layout of the water pipe 2 does not interfere with the third heat dissipation duct 1306.

[0089] In addition, to enhance the heat dissipation effect of the controller 31 and avoid interference between the layout of the water pipe 2 and the third heat dissipation duct 1306, in another embodiment, the fifth mounting slot 1318 can be positioned close to the first mounting slot 1311 or the second mounting slot 1313, in which case the fifth protruding edge 13159 is not required, and both the first protruding edge 13151 and the second protruding edge 13153 are provided with the ventilation opening 1309.

[0090] It is also important to note that the configuration of the first heat dissipation duct 1302, the second heat dissipation duct 1304, and the third heat dissipation duct 1306 inside the housing 1 is all related to the application scenario of the intelligent temperature-controlled seat cushion 100. The intelligent temperature-controlled seat cushion 100 is mainly used to place between the user's buttocks and the seat (or other seating area), and its usage environment is somewhat limited, imposing restrictions on the height and size of the housing 1. Therefore, unlike usage scenarios such as medical and health care, the heat exchange module 37 and the controller 31 can be set separately, and a large heat dissipation structure can be set to achieve temperature control and heat dissipation effects. The intelligent temperature-controlled seat cushion 100 configuration provided in this application achieves temperature control while having good heat dissipation effects under conditions of small space and low height. Of course, without changing the design concept and purpose of this application, those skilled in the art can make some layout modifications based on this embodiment, such as increasing the structural form and quantity of the heat exchange component 371, the heat pipe 373, and the heat sink 375 in the plane, and correspondingly setting multiple heat dissipation channels to achieve heat dissipation effects.

[0091] In addition, the supporting sidewall 133 of the lower cover 13 can also have at least one mounting hole 13105 for mounting the switch button 39. The mounting hole 13105 is set relatively close to the inclined side, so that the switch button 39 is as close as possible to the power supply 33 after installation, the connection line will not affect the heat dissipation channels, and it is convenient for the user to press and control during use.

[0092] Please continue to refer to the following: Figure 13 In another embodiment, the lower cover 13 may also have a wire groove 1319 near the fourth mounting slot 1317 for installing the charging cable 6. One end of the cable 6 is connected to the power source 3, and the other end extends outward from the housing 1 for charging the power source 3. The wire groove 1319 includes a hollow portion 13191 that communicates with the receiving space 101 and a serrated portion 13193 that cooperates to limit the cable 6. The serrated portions 13193 are alternately spaced on both sides of the wire groove 1319, and the specific number is not limited, so as to facilitate the installation and removal of the cable 6 into the wire groove 1319, and the cable 6 is not easy to fall out due to the restriction of the serrated portions 13193.

[0093] When the intelligent temperature-controlled seat cushion 100 needs charging, the cable 6 is removed from the cable groove 1319, which can extend the charging distance. The hollow part 13191 is located at either end of the cable groove 1319, and the charging cable 6 passes through the hollow part 13191 and is connected to the controller to charge the power supply 33. In addition, the intelligent temperature-controlled seat cushion 100 is charged through the cable 1319, rather than having a fixed charging port directly on the controller 31, which can effectively prevent damage to the charging port caused by the user rotating or moving the intelligent temperature-controlled seat cushion.

[0094] Please continue reading, 3. Figure 4 and Figure 5 The controller 31 includes a storage module 311, a drive module 312, a temperature detection module 313, a temperature control module 314, a processing module 315, a display module 316, and a wireless connection module 317. The storage module 311 is connected to the processing module 315 and is used to store the control program in advance for retrieval by the processing module 315 according to instructions. The drive module 312, the temperature control module 314, the temperature detection module 313, the display module 316, and the wireless connection module 317 are all connected to the processing module 315 for signal transmission. The drive module 312 is electrically connected to the pump 35 and the fan 38, controlling their operating states. The temperature control module 314 is connected to the heat exchange module 37, controlling its operating state and efficiency. The display module 316 may have multiple indicator lights or a small display screen to display information such as the operating mode, the temperature of the circulating liquid 4, and alarms. The wireless connection module 317 can select existing Bluetooth or Wi-Fi connection methods to match and connect to mobile terminal devices, so that users can monitor the status of the smart temperature-controlled seat cushion 100 and perform human-computer interaction operations such as wireless control through the mobile terminal devices.

[0095] In this embodiment, the cushion 91 is provided with a first receiving groove 901 and a second receiving groove 903. The first receiving groove 901 is located on the side of the cushion 91 near the edge of the supporting inclined surface 113 and away from the housing 1. Multiple indicator lights are spaced apart in the receiving groove 901. This arrangement does not affect user comfort and allows for easy viewing of the status display. The second receiving groove 903 is located in the middle area of ​​the cushion 91 and is used to accommodate the circulating fluid bag 7. The second receiving groove 903 effectively restricts the position of the circulating fluid bag 7.

[0096] The temperature detection module 313 includes a temperature sensor for detecting the temperature of the circulating liquid 4. The temperature sensor can use an NTC thermistor for temperature measurement. In this embodiment, a first temperature sensor 3131 is disposed between the circulating liquid bag 7 and the heat exchange module 37, and a second temperature sensor 3133 is disposed between the circulating liquid bag 7 and the storage tank 5. The processing module 315 simultaneously receives the first temperature signal D1 detected by the first temperature sensor 3131 and the second temperature signal D2 detected by the second temperature sensor 3133. In cooling mode, after the user sets the target temperature D0, the difference between the first temperature D1 and the target temperature D0 is calculated. If the difference is greater than a first preset threshold Dt1, the processing module 315 controls the temperature control module 314 to switch to full power mode, increasing the operating power of the heat exchange module 37; when the first temperature D1 reaches the target temperature D0, the temperature control module 314 switches to low power mode, maintaining the heat exchange module 37 in low power operation.

[0097] In normal operation, the difference between the first temperature D1 and the second temperature D2 is continuously monitored to determine whether there is a noticeably heated object above the smart temperature-controlled seat cushion 100. When the difference between the first temperature D1 and the second temperature D2 is consistently lower than the second preset threshold Dt2 within a preset time period Tt, it indicates that the user or other heated object has not been present for an extended period. The processing module 315 enters standby mode, controlling the temperature control module 314 to stop working, but keeping the pump 35 running continuously. When a change in the difference between the first temperature D1 and the second temperature D2 is detected, and it exceeds the second preset threshold Dt2, it indicates that a heated object, such as a human body, has come into contact with the smart temperature-controlled seat cushion 100 again, and the temperature control module 314 restarts operation.

[0098] The intelligent temperature-controlled seat cushion 100, by setting the temperature detection module 313 to work in conjunction with the temperature control module 314 and the processing module 315, can not only improve temperature control efficiency and ensure that the circulating liquid 4 reaches the target temperature D0 set by the user as soon as possible, thus improving the user experience, but also effectively save energy by automatically detecting the user's usage status and flexibly controlling the operating power of each module.

[0099] Furthermore, the processing module 315 can retrieve a preset temperature from the storage module 311 and combine it with the ambient temperature to calculate a comprehensive intelligent preset seat cushion temperature. This preset temperature is scientifically set based on the human buttock temperature, making it suitable for a wider range of users. After the user selects the intelligent mode with a single click, the processing module 315 automatically retrieves, calculates, and controls the temperature, making operation simple and highly intelligent. It should be noted that the first preset threshold Dt1, the second preset threshold Dt2, and the preset time period Tt can all be preset as needed, or set by the user according to their own habits; no restrictions are imposed here.

[0100] The controller 31 can also be equipped with a water level monitoring module 318, which can be installed at any location in the circulation path or the storage tank 5 and connected to the processing module 315 to detect the water level. For example, the water level monitoring module 318 includes two wires, spaced apart on both sides through which the circulating liquid 4 can flow. When the circulating liquid 4 flows through, the two wires are connected; when air flows through, the two wires are disconnected. Both connections are transmitted to the processing module 315 to determine whether air is present in the circulating liquid 4. If the connection is interrupted for an extended period, it indicates that the storage tank 5 is low on circulating liquid 4, and the processing module 315 notifies the user to replenish the liquid via the display module 316 or the wireless connection module 317.

[0101] The circulating liquid 4 described in this application can be composed of water or a solution that easily transfers temperature, such as a refrigerant or heating agent. The water pipe 2 is a plastic pipe used in the prior art to transport the circulating liquid 4. The specific materials, dimensions, or volume parameters can be set as needed and are not limited here.

[0102] In this embodiment, taking the user's need to reduce the temperature of the buttocks as an example, the specific control and circulation steps are briefly described as follows:

[0103] The user sets the target temperature D0 or sets the smart mode via the switch button 39 or the wireless connection module 317, thus generating a control signal.

[0104] After receiving the control signal, the processing module 315 in the controller 31 controls the temperature control module 314 and the drive module 312 to enter the corresponding working mode. One side of the heat exchange component 371 in the heat exchange module 37 starts to cool down, and the heat generated on the other side is transferred to the heat exchange component 371 through the heat pipe 373.

[0105] The drive module 312 controls the working state of the pump 35 and the fan 38. The fan 38 forms airflow in the first heat dissipation duct 1302, the second heat dissipation duct 1304 and the third heat dissipation duct 1306 to carry away the heat generated by the heat exchange component 371 and the controller 31.

[0106] The pump 35 drives the circulating liquid 4 to start flowing. After the temperature is adjusted by the heat exchange component 371, the circulating liquid 4 enters the circulating liquid bag 7, exchanges temperature with the human buttocks, and then flows into the storage tank 5. After passing through the storage tank 5 and the pump 35, it returns to the position of the heat exchange component 371 for temperature adjustment, thus completing the circulation.

[0107] Compared to existing technologies, the intelligent temperature-controlled seat cushion 100 provided in this application arranges the controller 31, the heat exchange module 37, the liquid storage tank 5, and the circulating liquid bag 7 in conjunction with the housing 1 to form an ergonomic seat cushion that can intelligently adjust the seat cushion temperature according to user settings.

[0108] The heat exchange component 371, the heat pipe 373, and the heat sink 375 cooperate with the fan 38 and are disposed on the same plane on the lower cover 13, forming the first heat dissipation air duct 1302, the second heat dissipation air duct 1304, and the third heat dissipation air duct 1306 within the housing 1, thereby improving the heat dissipation efficiency within the housing 1. The spaced first mounting slot 1311, the second mounting slot 1313, the third mounting slot 1315, the fourth mounting slot 1317, and the fifth mounting slot 1318 allow for a distributed layout of the various parts of the temperature control circulation device 3, reducing the overall height of the housing 1 and facilitating user seating. In use, the temperature control circulation device 3 and the liquid storage tank 5 are respectively installed in each mounting slot. The controller 31 is located in the third mounting slot 1315 in the center. The heat exchange module 37 and the power supply 33 are respectively located in the second mounting slot 1313 and the fourth mounting slot 1317 on both sides. The liquid storage tank 5 is located in the first mounting slot 1311, which is adjacent to the second mounting slot 1313. The overall layout shortens the length of the water pipe 2 and the cable 6. The layout is scientific and reasonable. While realizing the function, it avoids unnecessary cross interference, improves the safety and reliability of the intelligent temperature control seat cushion 100, and reduces production costs.

[0109] The liquid storage tank 5 divides the liquid-containing space 501 into the liquid storage chamber 5013 and the flow chamber 5011 by setting the isolation strip 536 between the first cover 51 and the second cover 53. This restricts the circulating liquid 4 stored in the liquid storage chamber 5013 from participating in circulation, thereby reducing the energy loss of the heat exchange module 37 during operation. Similarly, the intelligent temperature-controlled cushion 100 is equipped with a temperature detection module 313 to monitor the temperature of the circulating liquid 4 at the entry and exit positions of the circulating liquid bag 7, thereby achieving intelligent temperature control while reducing energy consumption.

[0110] The circulating liquid 4 can be replenished into the circulation system through the storage chamber 5013 in the storage tank 5. The injection port 5101, the force-bearing part 537, and the sliding groove 538 cooperate with the first mounting groove 1311 in the lower cover 13, making it easy for the user to push and pull the storage tank 5 and replenish the circulating liquid 4 in a timely manner. The intelligent temperature-controlled seat cushion 100 also uses the water level monitoring module 318 to detect the liquid level of the circulating liquid 4 in the circulation system, promptly reminding the user of liquid shortage, preventing the system from running dry or gas from entering the circulating liquid bag 7, and ensuring safe use.

[0111] The fifth protruding edge 13159 is positioned relative to the first protruding edge 13151 and the second protruding edge 13153, forming a water pipe channel 13103 that is spaced apart from and does not interfere with the first heat dissipation air duct 1302, the second heat dissipation air duct 1304 and the third heat dissipation air duct 1306, ensuring dry and wet separation and ensuring the safe use of the controller 31.

[0112] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
