Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seats, in particular to a temperature control system and a seat. BACKGROUND

[0002] Traditional seat temperature control systems mostly use electric heating wires or water circulation systems to achieve heating or cooling functions. The electric heating wire heating system heats the resistance wire through electric current to generate heat and transfer it to the user through the seat material. Although the heating effect is significant, the energy consumption is high, and the temperature adjustment range is limited. Long-term use may also cause local overheating, affecting the user experience. The water circulation system uses a circulating pump to send cooled or heated water into the pipes inside the seat to adjust the temperature of the seat. However, the water circulation system has a complex structure, high maintenance cost, and high sealing requirements for water. Once the water leaks, not only the temperature control effect is affected, but also the seat and the surrounding environment may be damaged.

[0003] In addition, when adjusting the temperature, the traditional temperature control system often has difficulty in achieving rapid and accurate temperature changes. The electric heating wire heating needs a certain time to reach the set temperature, and the response speed of the water circulation system is slower, which cannot meet the user's demand for instant temperature control. At the same time, these systems also have certain limitations in temperature control accuracy, and cannot provide users with more detailed temperature adjustment experience.

[0004] In addition, when controlling the temperature of the seat, not only the temperature problem needs to be considered, but also the humidity problem of the seat or the space environment where the seat is located. The existing ventilation is mostly in the form of fan blowing, which cannot achieve rapid cooling of the seat, and if the environmental temperature is too high, the effect of fan ventilation is limited. When the user sits on the seat, if the temperature in the seat or cabin is too high and sweats, two factors will affect the user's riding experience, one is the temperature, and the other is the humidity, which will cause the humidity to rise. At this time, only cooling cannot immediately make the user feel the most comfortable state; the moisture also needs to be removed, which will make the user's experience better. Moreover, the existing ventilation and heating scheme adopts a whole seat arrangement, but the user does not contact the whole surface of the seat, which makes the efficiency of ventilation and heating not very high, and some wind or heat does not have effect on the real-time temperature perception of the passenger.

[0005] Based on the above, it is necessary to develop a new temperature control system to overcome the drawbacks of the traditional temperature control system. CONTENT OF THE INVENTION

The controller is used to adjust the flow ratio of the heat source outlet and the cold source outlet. In this temperature control system, the vortex tube serves as the core component for temperature regulation. A vortex tube is a device that utilizes compressed air to generate cold and hot effects. It can separate the input compressed air into two airflows, cold and hot. By adjusting the flow ratio of the cold and hot airflows, precise temperature control can be achieved. Compared with traditional temperature control systems, the temperature control system using a vortex tube has advantages such as simple structure, convenient maintenance, low energy consumption, fast response speed, and high temperature regulation accuracy.

[0050] Example 1

[0051] This application provides a seat 1000, please refer to... Figure 1 The seat 1000 includes a temperature control system 100. The seat 1000 has a seat 101, a backrest 102, and a leg rest 103, and may also have armrests (not shown). For the specific implementation and function of the temperature control system 100, please refer to the following embodiments.

[0052] It is worth noting that the seat 1000 can be installed on any means of transportation, such as cars, airplanes, or ships.

[0053] Example 2:

[0054] This application provides a temperature control system 100, which can be referred to in conjunction with other relevant documents. Figure 1 and Figure 2 The temperature control system 100 includes a temperature control component 30, an air source 40, and a controller (not shown). The temperature control component 30 includes a vortex tube 301 and an air bag assembly 302. The vortex tube 301 has a fluid inlet 3011, a heat source outlet 3012, and a cold source outlet 3013. Both the heat source outlet 3012 and the cold source outlet 3013 are connected to the air bag assembly 302. The air bag assembly 302 is used to install inside the seat 1000 and in direct contact with the user. The air source 40 is used to provide continuous compressed air and is connected to the fluid inlet 3011. The controller is used to control the opening and closing of the air passages between the air source 40, the air bag assembly 302, and the vortex tube 301, respectively. The controller is used to adjust the flow rate ratio of the heat source outlet 3012 and the cold source outlet 3013. The temperature control system 100 utilizes a vortex tube 301, a device that generates cooling and heating effects using compressed air. It separates the input compressed air into two streams of air: cold and hot. By adjusting the ratio of the cold and hot air streams, precise temperature control can be achieved. In this embodiment, when cold and hot air streams are introduced into the air bag assembly 302 through the vortex tube 301, the temperature of the air bag assembly 302 is adjusted, thereby regulating the temperature of the seat 1000 and improving the comfort of the user sitting in the seat 1000.

[0055] Furthermore, compared to traditional methods of temperature regulation using heating wires or water circulation, the temperature control system 100 provided in this embodiment uses a vortex tube 301, which offers advantages such as simple structure, convenient maintenance, low energy consumption, fast response speed, and high temperature regulation accuracy. Simultaneously, the vortex tube 301 eliminates the need for water or other liquid media, avoiding potential risks such as water leakage and improving the safety and reliability of the temperature control system 100.

[0056] In some embodiments of the temperature control component 30, the air bag assembly 302 in the temperature control component 30 is also connected to a return pipeline (not shown in the figure). The return pipeline is connected to the air inlet 401 of the air source 40. Through the return pipeline, the hot and cold airflow entering the air bag assembly 302 can return to the air source 40 after the temperature of the air bag assembly 302 is regulated, thereby improving the energy efficiency.

[0057] It is worth noting that the airbag assembly 302 is disposed on at least one of the seat 101, backrest 102, armrest (not shown) and leg 103 of the seat 1000, and the airbag assembly 302 is disposed on the side of the seating space of the seat 1000.

[0058] It is worth noting that, in order to improve the user experience, in some embodiments, the airbag assembly 302 includes a first airbag 3021, a second airbag 3022, a third airbag 3023, and a fourth airbag 3024; the first airbag 3021 is connected to the heat source outlet 3012 and the cold source outlet 3013 respectively, and the first airbag 3021 is used to be disposed in the middle of the backrest 102 of the seat 1000; there are two second airbags 3022, both of which are connected to the first airbag 3021, and the second airbags 3022 are used to be disposed in the backrest 102 of the seat 1000; the third airbag 3023 is connected to the first airbag 3021, and the third airbag 3023 is used to be disposed in the middle of the seat portion 101 of the seat 1000; there are two fourth airbags 3024, both of which are connected to the third airbag 3023, and the fourth airbags 3024 are used to be disposed in the seat portion 101 of the seat 1000. By configuring the first airbag 3021, the second airbag 3022, the third airbag 3023, and the fourth airbag 3024, when a user sits on the seat 1000, the user can feel the temperature change as quickly as possible with minimal energy consumption. Specifically, the first airbag 3021, the second airbag 3022, the third airbag 3023, and the fourth airbag 3024 are configured on the area of ​​the seat 1000 that is in contact with the user's body, while no airbags are configured on the area where the user's body is not in contact with the seat 1000. This allows the user to quickly feel the temperature change while also taking into account energy consumption.

[0059] Please see Figure 3 , Figure 3This is a partition diagram of the seat 1000. The backrest 102 of the seat 1000 has a backrest area 1021, a left lower back area 1022, and a right lower back area 1023. The backrest area 1021 can contact the user's back, and the left lower back area 1022 and right lower back area 1023 can contact the user's lower back. The backrest area 1021 is used for the first airbag 3021, and the left lower back area 1022 and right lower back area 1023 are respectively used for the two second airbags 3022.

[0060] The seat 1000 has a hip area 1011 in its seat portion 101. The hip area 1011 is in contact with the user's hips and is used for the placement of the third airbag 3023. The leg portion 103 of the seat 1000 has a left leg area 1031 and a right leg area 1032, which are in contact with the user's legs. The left leg area 1031 and the right leg area 1032 are used for the placement of the two fourth airbags 3024, respectively.

[0061] It is worth noting that in some embodiments, two second airbags 3022 are distributed on both sides of the first airbag 3021. The second airbags 3022 are positioned closer to the seat portion 101 of the seat 1000, while the first airbags 3021 are positioned further away from the seat 1000. The first airbag 3021 corresponds to the user's back, and the second airbags 3022 correspond to the user's lower back. With this arrangement, the temperature in the first airbag 3021 can act on the user's back, and the temperature in the second airbag 3022 can act on both sides of the user's lower back, thereby further improving the user experience.

[0062] It is worth noting that in some embodiments, two fourth airbags 3024 are distributed on both sides of the third airbag 3023. The fourth airbags 3024 are positioned away from the backrest 102 of the seat 1000, while the third airbag 3023 is positioned closer to the backrest 102 of the seat 1000. The third airbag 3023 corresponds to the user's buttocks, and the fourth airbags 3024 correspond to the user's legs. Through these third airbags 3023 and fourth airbags 3024, the temperature in the third airbag 3023 can act on the user's buttocks, and the temperature in the fourth airbag 3024 can act on the user's legs, thereby further enhancing the user's comfort.

[0063] It is worth noting that in some embodiments, the airbag assembly 302 further includes two fifth airbags (not shown). These fifth airbags are connected to any one of the first airbag 3021, second airbag 3022, third airbag 3023, and fourth airbag 3024. The two fifth airbag assemblies are respectively used to install on the two armrests of the seat 1000. Through these fifth airbags, when the user rests their arms on the armrests of the seat 1000, the temperature from the fifth airbags can be applied to the user's arms.

[0064] It is worth noting that in some embodiments, the arrangement of the air bag group 302 is not limited to the first air bag 3021, the second air bag 3022, the third air bag 3023, the fourth air bag 3024, and the fifth air bag described above. Other implementations are also possible. For example, please refer to [link to relevant documentation]. Figure 4 The airbag assembly 302 includes only a first airbag 3021 and a third airbag 3023. The first airbag 3021 is located on the backrest 102 of the seat 1000, and the third airbag 3023 is located on the seat portion 101 of the seat 1000. Through the placement of the first airbag 3021 and the third airbag 3023, the temperature of the first airbag 3021 corresponds to the user's back, and the temperature of the third airbag 3023 corresponds to the user's buttocks, thus providing warmth to most areas of the user's body. This not only saves energy but also improves the user experience. The first airbag 3021, second airbag 3022, third airbag 3023, fourth airbag 3024, and fifth airbag can generally be made of aluminum or other sheets with high thermal conductivity. This allows for the fastest transfer of temperature changes within each airbag to the corresponding surface of the seat 1000. Furthermore, each airbag generally has a flat structure, resulting in higher energy efficiency.

[0065] It is worth noting that in some embodiments, the temperature control system 100 also includes an air storage tank 50, which is disposed between the air source 40 and the fluid inlet 3011. The air storage tank 50 is used to increase the pressure of the continuous compressed air provided by the air source 40. By providing the air storage tank 50, the rate of the hot and cold airflow generated by the vortex tube 301 can be increased, thereby improving the response rate of the temperature control system 100 to temperature control.

[0066] Understandably, the gas storage tank 50 is connected to the controller, which can control the on / off state of the gas storage tank 50.

[0067] The air source 40 can be any device that can provide compressed air.

[0068] The controller described above is the control center of the temperature control system 100 in this embodiment of the application. The controller is used to control the opening and closing of the air passage between the air source 40, the air bag assembly 302 and the vortex tube 301; the controller is used to adjust the flow ratio of the heat source outlet 3012 and the cold source outlet 3013.

[0069] It is worth noting that in some embodiments, the temperature control system 100 further includes a first control valve 60a, a second control valve 60b, and a third control valve 60c, respectively connected to the controller. The first control valve 60a is located between the air source 40 and the fluid inlet 3011 of the vortex tube 301; the second control valve 60b is located between the heat source outlet 3012 of the vortex tube 301 and the air bag assembly 302; and the third control valve 60c is located between the cold source outlet 3013 of the vortex tube 301 and the air bag assembly 302. The controller is used to control the opening and closing of the air passage between the air source 40 and the vortex tube 301 through the first control valve 60a. The controller can also control the rate and flow rate of compressed air input from the air source 40 to the vortex tube 301 through the first control valve 60a. The controller controls the flow of air between the heat source outlet 3012 of the vortex tube 301 and the air bag assembly 302 via the second control valve 60b. The controller can also control the rate and flow rate of the hot airflow input from the heat source outlet 3012 of the vortex tube 301 to the air bag assembly 302 via the second control valve 60b. The controller also controls the flow of air between the cold source outlet 3013 of the vortex tube 301 and the air bag assembly 302 via the third control valve 60c. The controller can also control the rate and flow rate of the cold airflow input from the cold source outlet 3013 of the vortex tube 301 to the air bag assembly 302 via the third control valve 60c.

[0070] It is worth noting that, through the controller, the second control valve 60b and the third control valve 60c, the controller can control the ratio of the flow rate of the heat source outlet 3012 of the vortex tube 301 to the flow rate of the cold source outlet 3013 of the vortex tube 301 by controlling the second control valve 60b and the third control valve 60c, thereby controlling the temperature of the air bag assembly 302.

[0071] It is worth noting that the first control valve 60a, the second control valve 60b, and the third control valve 60c can all be valves such as solenoid valves, proportional valves, pilot valves, piezoelectric valves, and multi-way valves that can control the direction and / or flow rate of the air path; generally, proportional valves can be used, which can simultaneously control the flow rate of the fluid in the corresponding pipeline.

[0072] When the temperature control system 100 includes an air tank 50, the controller is also used to control the on / off state of the air tank 50. The controller can also control the output power of the air tank 50, thereby adjusting the pressure of the continuous compressed air supplied by the air source 40.

[0073] It is worth noting that the program steps involved in the controller are existing program steps, and the controller also uses existing processors, such as Intel's i3 processor, AMD Ryzen processor, etc.

[0074] In some embodiments, the temperature control system 100 further includes a ventilation device 10, see [link to relevant documentation]. Figure 1The ventilation device 10 is connected to the air source 30 and is installed on the seat 1000. The ventilation device 10 cools the seating space of the seat 1000 and removes moisture from the seating space, improving the user experience.

[0075] In some embodiments, please refer to the following: Figure 1 and Figure 2 The ventilation device 10 includes a ventilation pad 1 and a ventilation duct 2. The ventilation pad 1 is installed inside the seat 1000 to blow or draw air into the seat 1000 for heat dissipation. The ventilation duct 2 is connected to an air source 40. When the air source 40 supplies gas to the ventilation duct 2, a negative pressure is created within the ventilation duct 2, allowing one end of the ventilation duct 2 to draw in gas and the other end to discharge gas. One end of the ventilation duct 2 is connected to the ventilation pad 1, thus enabling blowing or drawing air into the ventilation pad 1. A controller is used to control the flow of air between the air source 40 and the ventilation duct 2, i.e., to control whether the continuous compressed air provided by the air source 40 is supplied to the ventilation duct 2. By setting up a temperature control system 100 for the ventilation device 20, the temperature control component 30 in the temperature control system 100 and the ventilation device 20 share the air source 40, which helps to reduce costs and enables more intelligent temperature and humidity regulation. In other words, when the temperature of the seat 1000 is adjusted by the temperature control component 30, the ventilation device 20 can also generate a strong suction effect on the seat 1000 to quickly remove the moisture generated by sweat, so that the seat 1000 can quickly reach the appropriate temperature and humidity conditions, resulting in a better user experience; and the temperature control component 30 and the ventilation device 20 share the same air source, which is also more cost-effective.

[0076] When the temperature control system 100 includes a first control valve 60a, the first control valve 60a has multiple valve bodies (generally multiple solenoid valves or SMA (Shape Memory Alloy) valve bodies) for controlling the airflow and rate to the ventilation device 10.

[0077] It should be noted that the ventilation pad 1 is installed inside the seat 1000 only as an example to illustrate its heat dissipation effect on the seat 1000. The ventilation pad 1 can also be installed on other external devices to ventilate or dissipate heat from the external devices.

[0078] For the ventilation pad 1 mentioned above, please refer to Figure 2 and Figure 5The ventilation pad 1 includes a sealing sleeve 11 and a breathable partition 12 enclosed inside the sealing sleeve 11. One side of the sealing sleeve 11 has multiple first ventilation holes 111, and the other side has multiple second ventilation holes 112. Alternatively, the sealing sleeve 11 may have only one second ventilation hole 112. The breathable partition 12 is mesh-like, allowing airflow to pass through it and providing support to prevent the fluid passage from being blocked when the sealing sleeve 11 is under pressure.

[0079] The first ventilation hole 111 faces the seating space of the seat 1000, which is used for user seating. When the first ventilation hole 111 draws in or blows air, it can remove air from the user's surroundings, thereby dissipating heat from the seating space. The ventilation pad 1 is located inside the seat 1000 or is part of the seat 1000. When the first ventilation hole 111 draws in or blows air, it also dissipates heat from the seat 1000.

[0080] The seating space includes not only the seat and backrest of the seat 1000, forming a semi-enclosed space, but also the space where the user moves while seated in the seat 1000. This includes, for example, the space for the user's legs and surrounding area, the space for arm movement, and the space for head movement.

[0081] The multiple first ventilation holes 111 may include multiple first ventilation holes 111 of different shapes and sizes, thereby providing different intake and exhaust effects. For example, one of the first ventilation holes 111 on the sealing sleeve 11 may be circular, another may be rectangular, and yet another may be triangular, etc. For example, the sealing sleeve 11 may have multiple circular first ventilation holes 111, one of which has a diameter of 1 cm, another has a diameter of 2 cm, and yet another has a diameter of 3 cm, etc.

[0082] In some embodiments, the number of first ventilation holes 111 is greater than the number of second ventilation holes 112. That is, the ventilation pad 1 has a diversion function, which helps to form a greater number of air intake or air blowing ports in the seat 1000, thereby improving the uniformity of air blowing or inhaling from the seat 1000 to the user.

[0083] The second ventilation hole 112 is positioned opposite to the first ventilation hole 111, meaning that the first ventilation hole 111 and the second ventilation hole 112 are located on opposite sides of the ventilation pad 1, for example, on opposite sides of the ventilation pad 1 along its thickness direction. This allows gas to pass through the ventilation pad 1 in one direction, which helps reduce the resistance encountered by the gas within the ventilation pad 1, reduces gas energy loss, and improves the heat dissipation effect on the seat 1000. Furthermore, in this embodiment, the first ventilation hole 111 and the second ventilation hole 112 are located on opposite sides of the ventilation pad 1 along its thickness direction, which helps to shorten the path length of the gas flow within the ventilation pad 1 and reduce gas energy loss.

[0084] When the ventilation pad 1 has multiple second ventilation holes 112, the ventilation device 10 includes multiple ventilation pipes 2. The number of ventilation pipes 2 is equal to the number of second ventilation holes 112, and each ventilation pipe 2 is connected to one second ventilation hole 112. At this time, the controller is connected to multiple ventilation pipes 2, and the controller is used to independently control the opening and closing of the air passage between the air source 40 and any one of the ventilation pipes 2. This allows control over the airflow rate of the ventilation pad 1 for intake or exhaust, and control over the heat dissipation intensity of the seat 1000. The ventilation pipes 2 can have various models, and different models of ventilation pipes 2 have different shapes and / or sizes, thus providing different intake and exhaust effects. Multiple ventilation pipes 2 connected to the same ventilation pad 1 can include various models, meaning that one ventilation pad 1 is equipped with multiple models of ventilation pipes 2.

[0085] The ventilation pad 1 is flat, making it easy to cover the frame of the seat 1000 or to be placed inside the seat 1000, minimizing its impact on the size of the seat 1000. The ventilation pad 1 can be used directly as a cover layer for the seat 1000, reducing the resistance to ventilation caused by the original cover layer and allowing for a smaller seat 1000 size. Optionally, the ventilation pad 1 is rectangular. Optionally, the ventilation pad 1 is adapted to the shape of the cover layer on the seat 1000, thus directly replacing the original cover layer of the seat 1000.

[0086] The sealing sleeve 11 is elastic or plastic. When a user sits on the seat 1000 and applies pressure to the sealing sleeve 11, the sealing sleeve 11 can deform, thereby improving the user's seating comfort. The sealing sleeve 11 can be made of genuine leather, artificial leather, plastic, rubber, silicone, etc.

[0087] In some embodiments, please refer to Figure 5The sealing sleeve 11 includes a first layer 113 and a second layer 114. The first layer 113 is disposed within the second layer 114. The first layer 113 is used to form a seal, and the second layer 114 is used to contact the user, thereby improving the user's riding comfort and enhancing the airtightness of the sealing sleeve 11. Optionally, the first layer 113 is made of a material with good airtightness, such as rubber or silicone, and the second layer 114 is made of a skin-friendly and wear-resistant material, such as genuine leather or artificial leather.

[0088] It should be noted that when air is drawn in or blown into the sealing sleeve 11, the sealing sleeve 11 will expand or contract due to changes in internal air pressure, affecting the shape of the seat 1000 and the user's comfort. The breathable layer 12, supported within the ventilation pad 1, can support the sealing sleeve 11 when air is drawn in, mitigating the contraction problem. The breathable layer 12 can be bonded to the inner wall of the sealing sleeve 11, and when air is blown into the sealing sleeve 11, it can hold the sealing sleeve 11 in place, mitigating its expansion. Optionally, the breathable layer 12 can be made of plastic, metal, or other materials, possessing a certain strength and elasticity to address the issues of the ventilation pad 1's tendency to collapse and excessive rigidity, which can lead to poor seating comfort in the seat 1000.

[0089] The breathable spacer 12 is adapted to the shape of the inner cavity of the sealing sleeve 11. For example, when the sealing sleeve 11 is a rectangular sheet, the breathable spacer 12 is also a rectangular sheet. Please refer to [link / reference]. Figure 6 The breathable barrier 12 has gas channels 121 along its thickness direction. Multiple gas channels 121 are arranged at intervals along the length and width directions of the breathable barrier 12, so that gas can pass through the breathable barrier 12 along its thickness direction, reducing the obstruction of the breathable barrier 12 to the gas and reducing gas energy loss.

[0090] In this design, a gap exists between the breathable partition 12 and the inner wall of the sealing sleeve 11 along the thickness direction of the breathable partition 12, allowing gas to flow in a direction perpendicular to the thickness of the breathable partition 12. It is understood that the first ventilation hole 111 and the second ventilation hole 112 may not be directly aligned along the thickness direction of the ventilation pad 1. Therefore, gas needs to flow a certain distance perpendicular to the thickness of the ventilation pad 1 before it can flow from one of the first ventilation hole 111 to the other. By providing a gap between the breathable partition 12 and the inner wall of the sealing sleeve 11, a channel perpendicular to the thickness direction of the ventilation pad 1 can be formed. This not only allows gas flow between the first ventilation hole 111 and the second ventilation hole 112 but also makes the suction or blowing intensity of the multiple first ventilation holes 111 more uniform. In some other embodiments, the breathable partition 12 also has a gas channel 121 perpendicular to its thickness direction.

[0091] For ventilation duct 2 mentioned above, please refer toFigure 5 and Figure 7 The ventilation duct 2 includes a constriction section 21, a throat section 22, and an expansion section 23 connected in sequence. One end of the constriction section 21, away from the throat section 22, is connected to a second ventilation hole 112. The ventilation duct 2 also includes a conduit 24, one end of which is disposed within the constriction section 21 with its port facing the expansion section 23. In this embodiment, the end of the constriction section 21 away from the throat section 22 is connected to the second ventilation hole 112; the air source 40 is connected to the other end of the conduit 24, and a controller is used to control the opening and closing of the air passage between the air source 40 and the conduit 24. For example, the controller is disposed on the pipe between the air source 40 and the conduit 24.

[0092] When gas is introduced from the air source 40 into the duct 24, the gas is ejected from the contraction section 21 toward the expansion section 23, and the surrounding gas flows toward the expansion section 23, thereby creating a negative pressure within the contraction section 21. Since the contraction section 21 is connected to the first ventilation hole 111 through the second ventilation hole 112, it draws away the gas near the first ventilation hole 111, i.e., it draws away the gas in the seating space, thus dissipating heat from the seating space and the seat 1000. Heat dissipation through suction, compared to blowing air, is beneficial for improving user comfort. Specifically, when the duct 24 ejects gas from the contraction section 21 toward the expansion section 23, it can generate a negative pressure in the contraction section 21 to draw in more gas. This small airflow drives a large airflow, increasing the amount of air drawn into the ventilation pad 1, enhancing the heat dissipation effect on the seating space and the seat 1000, improving heat dissipation efficiency, and allowing the seat 1000 to cool down quickly. At the same time, the ventilation device 20 can quickly remove the moisture generated by sweat, and together with the temperature control component 30, it can adjust the temperature of the seat 1000, thereby enabling the seat 1000 to quickly reach a suitable temperature and humidity condition and improve the user experience.

[0093] Accordingly, the gas output flow rate and gas velocity of the air source 40 can be appropriately reduced to further reduce the noise of the seat 1000 and reduce the energy consumption of the air source 40.

[0094] The ventilation duct 2 can be made of plastic, metal, or other materials. When the ventilation duct 2 is made of plastic, it can be manufactured using 3D printing technology, which helps to reduce production costs.

[0095] In some embodiments, please refer to Figure 7 The contraction section 21, throat section 22, and expansion section 23 extend along the same axis. That is, the centerlines of the contraction section 21, throat section 22, and expansion section 23 coincide in pairs. When the gas passes through the contraction section 21, throat section 22, and expansion section 23, the gas does not need to go through bends, which helps to reduce the energy loss of the gas.

[0096] In some embodiments, please refer to Figure 5 and Figure 7The contraction section 21, throat section 22, and expansion section 23 are all rotating bodies. When the gas passes through the contraction section 21, it contracts uniformly from all sides towards the axis of the contraction section 21; when the gas passes through the expansion section 23, it expands uniformly in a direction away from the axis of the expansion section 23, which helps to reduce airflow turbulence and reduce gas energy loss.

[0097] For the contraction segment 21 mentioned above, please refer to Figure 7 Along the direction from the contraction section 21 to the throat section 22, the contraction rate of the contraction section 21 gradually decreases. As the gas passes through the contraction section 21, its contraction rate gradually decreases, and then abruptly drops to zero as the gas passes through the throat section 22. By gradually decreasing the gas's contraction rate, the degree of this abrupt change can be reduced, thereby weakening the intensity of the vortex rings caused by this abrupt change in gas contraction rate. When the gas generates vortex rings within the ventilation duct 2, a significant amount of energy loss occurs; therefore, gradually decreasing the contraction rate of the contraction section 21 helps to reduce this energy loss.

[0098] In this embodiment of the application, the shrinkage rate of the shrinkage section 21 refers to the rate of change of the inner diameter of the shrinkage section 21, and the expansion rate of the expansion section 23 refers to the rate of change of the inner diameter of the expansion section 23.

[0099] Please refer to Figure 7 At the junction of contraction segment 21 and throat segment 22, the contraction rate of contraction segment 21 is zero, meaning the tangent at the junction of contraction segment 21 and throat segment 22 is parallel to the axis of contraction segment 21. Therefore, when the gas flows from contraction segment 21 to throat segment 22, the contraction rate of the gas theoretically does not change abruptly, thus minimizing the energy loss of the gas.

[0100] For the above-mentioned laryngeal segment 22, please refer to Figure 7 , Figure 7 The dotted line in the middle is the throat section 22. The length of the throat section 22 is close to zero, that is, after the gas flows out of the contraction section 21, it immediately enters the expansion section 23, which helps to shorten the length of the ventilation pipe 2.

[0101] In some embodiments, please refer to Figure 7 The length of the contraction section 21 is shorter than the length of the expansion section 23. The gas flows in the expansion section 23 for a longer time than it flows in the contraction section 21, which can generate a greater negative pressure in the contraction section 21 and increase the air intake of the ventilation pipe 2 to the ventilation pad 1.

[0102] For the aforementioned expansion section 23, please refer to Figure 7Along the throat 22 towards the expansion section 23, the expansion rate of the expansion section 23 first gradually increases and then remains constant. When the gas passes through the throat 22, the expansion rate of the gas is zero. Then, when the gas passes through the expansion section 23, the expansion rate of the gas abruptly becomes greater than zero. By gradually increasing the expansion rate of the expansion section 23 first, the degree of this abrupt change can be reduced, thereby weakening the intensity of the vortex ring caused by the abrupt change in the gas's expansion rate, which is beneficial for reducing the energy loss of the gas.

[0103] Please refer to Figure 7 At the junction of expansion section 23 and throat section 22, the expansion rate of expansion section 23 is zero, meaning the tangent at the junction is parallel to the axis of expansion section 23. Therefore, when the gas flows from throat section 22 to expansion section 23, the expansion rate theoretically does not change abruptly, thus minimizing energy loss.

[0104] In this process, the expansion rate of expansion section 23 gradually increases first and then remains constant. Therefore, when the gas passes through expansion section 23, the expansion rate of the gas does not change abruptly, which is beneficial to reducing the energy loss of the gas. Figure 7 In the middle, the solid line between the expansion segment 23 and the throat segment 22 is the boundary line between the segment where the expansion rate of the expansion segment 23 gradually increases and the segment where the expansion rate of the expansion segment 23 remains constant. It can be understood that the tangents of these two segments of the expansion segment 23 at the boundary line are parallel to each other.

[0105] For catheter 24 mentioned above, please refer to Figure 7 The conduit 24 includes an inlet section 241 and an outlet section 242. The inlet section 241 is located within the wall of the contraction section 21, and the outlet section 242 communicates with the inlet section 241. The outlet section 242 is located within the contraction section 21, and its port faces the expansion section 23. By placing the inlet section 241 within the wall of the contraction section 21, it is advantageous to separate the pipe connected to the inlet section 241 from the end of the contraction section 21 facing away from the expansion section 23, reducing interference with the communication between the contraction section 21 and the second vent 112. Furthermore, it reduces the volume occupied by the conduit 24 within the contraction section 21, allowing the contraction section 21 to draw in more gas.

[0106] In some embodiments, please refer to Figure 7 The centerline of the ejector section 242 coincides with that of the converging section 21. That is, the ejector section 242 is positioned close to the centerline of the converging section 21, which helps to increase the air intake efficiency of the ventilation duct 2. Furthermore, the centerline of the ejector section 242 coincides with the centerline of the converging section 21 to further maximize the air intake efficiency of the ventilation duct 2.

[0107] In some embodiments, please refer to Figure 7The ejection section 242 is parallel to the axis of the ventilation duct 2. Therefore, when the gas is ejected from the ejection section 242, the airflow direction is parallel to the axis of the ventilation duct 2, and the airflow ejected from the ejection section 242 does not need to change its flow direction within the expansion section 23, which helps to reduce the energy loss of the gas.

[0108] In some embodiments, please refer to Figure 7 The inlet section 241 extends radially along the constriction section 21, and the conduit 24 is partially curved to connect with the inlet section 241. Exemplarily, the conduit 24 also includes a curved section 243, which is a bend in the tube and connects the inlet section 241 to the outlet section 242. It is understood that the angle between the axis of the inlet section 241 and the axis of the outlet section 242 is a right angle; if the gas directly enters the outlet section 242 from the inlet section 241, a significant amount of energy will be lost. Connecting the inlet section 241 and the outlet section 242 via the bend in the tube-like curved section 243 reduces this energy loss.

[0109] Furthermore, the curved section 243 smoothly connects the inlet section 241 and the outlet section 242. This smooth connection means that the tangents to the centerlines at both ends of the curved section 243 are parallel to the centerlines of the inlet section 241 and the outlet section 242, respectively, and the centerline of the curved section 243 is a curve. For example, the centerline of the curved section 243 can be an arc, a parabola, or an elliptical arc. Preferably, the centerline of the curved section 243 is an arc to minimize gas energy loss.

[0110] In some embodiments, please refer to Figure 7 The inlet section 241 includes a narrowing section 2411, the inner diameter of which gradually decreases along the radial direction of the contraction section 21. It can be understood that the airflow flows in the inlet section 241 towards the axis of the contraction section 21, thus causing the inner diameter of the narrowing section 2411 to gradually decrease in the direction towards the axis of the contraction section 21. By providing the narrowing section 2411, the cross-sectional area through which the gas flows is reduced, thereby increasing the airflow velocity.

[0111] In some embodiments, please refer to Figure 8 The ventilation duct 2 also includes a straight pipe section 25. One end of the straight pipe section 25 is connected to the second ventilation hole 112, and the other end of the straight pipe section 25 is connected to the end of the contraction section 21 opposite to the throat section 22. The inner diameter of the straight pipe section 25 is equal to the inner diameter of the end of the contraction section 21 opposite to the throat section 22. By providing the straight pipe section 25, it is easy for the ventilation duct 2 to connect with the second ventilation hole 112. The straight pipe section 25 can be partially inserted into the second ventilation hole 112, enhancing the airtightness of the connection between the ventilation duct 2 and the ventilation pad 1.

[0112] In some embodiments, please refer to Figure 9The ventilation duct 2 also includes a connector 26, which is located on the outer wall of the contraction section 21 and communicates with the conduit 24. The connector 26 is used to connect the duct, facilitating the connection between the ventilation duct 2 and the duct.

[0113] It is worth noting that the ventilation device 10 can be installed in the seat 101 or the backrest 102 of the seat 1000. Alternatively, it can be installed in both the seat 101 and the backrest 102 of the seat 1000. When both the seat 101 and the backrest 102 of the seat 1000 are equipped with ventilation devices 10, the two ventilation devices 10 can share the air source 40, which helps to reduce costs. Furthermore, one of the ventilation devices 10 may not require a ventilation pipe 2; instead, it can be connected to the sealing sleeve 11 of another ventilation device 10 via a pipe, for example, to the first ventilation hole 111 or the second ventilation hole 112 of the other ventilation device 10.

[0114] Example 3:

[0115] This application provides a temperature control method applied to seat 1000. Please refer to [link / reference]. Figure 10 The methods include:

[0116] S10: Obtain the target temperature.

[0117] Seat 1000 may include buttons or a touch screen, allowing users to input their desired target temperature.

[0118] The target temperature mentioned above can also be a temperature preset by the temperature control system, such as 37°C, which is the same as human body temperature, or 25°C, which is the normal temperature.

[0119] Understandably, the seat 1000 also includes a control device (not shown) for obtaining the target temperature via buttons or a touchscreen, and for controlling the air source 40 and the controller. The seat 1000 may also include a communication module that communicates with a network or nearby smart devices, allowing the target temperature to be input via a smart device such as a mobile phone, or via a wireless controller such as a remote control.

[0120] S20: Control the flow rate ratio of the heat source outlet and the cold source outlet according to the target temperature.

[0121] By controlling the flow rate of the heat source outlet 3012 and the flow rate of the cold source outlet 3013 respectively, the flow rate ratio between the two can be controlled. The hot and cold air flows converge in the air bag assembly 302, thereby adjusting the temperature of the air bag assembly 302 to achieve the target temperature.

[0122] Example 4:

[0123] This application provides a ventilation method applied to seat 1000. Please refer to [link / reference]. Figure 11 The methods include:

[0124] S100: Obtain ventilation mode.

[0125] Seat 1000 may include buttons or a touch screen, allowing users to input their desired ventilation mode.

[0126] Understandably, the seat 1000 also includes a control device (not shown) for obtaining the ventilation mode via buttons or a touchscreen, and for controlling the air source 40 and the controller. The seat 1000 may also include a communication module that communicates with a network or nearby smart devices, allowing the ventilation mode to be input via a smart device such as a mobile phone, or via a wireless controller such as a remote control.

[0127] S200: Controls the connection between the preset ventilation pipe 2 and the air source 40 according to the ventilation mode.

[0128] The ventilation mode includes at least one of ventilation area information and ventilation intensity information. Ventilation area information refers to the areas requiring ventilation, such as the seat 101, backrest 102, armrests, and legroom 103 of seat 1000. Ventilation intensity information refers to the ventilation intensity of the areas requiring ventilation, such as light breeze, medium breeze, or strong breeze.

[0129] When the ventilation mode includes ventilation area information, please refer to Figure 12 Step S200 includes:

[0130] S210: Obtain ventilation area information based on ventilation mode.

[0131] Ventilation zones can be named separately, such as ventilation zone A, ventilation zone B, etc., so the ventilation zone information can be ventilation zone A, ventilation zone B, etc.

[0132] S220: Obtain the preset number of ventilation duct 2 corresponding to the ventilation area information based on the ventilation area information.

[0133] The preset number of ventilation duct 2 corresponding to ventilation area A can be A, and the preset number of ventilation duct 2 corresponding to ventilation area B can be B. When one ventilation area corresponds to multiple ventilation ducts 2, the preset numbers of the multiple ventilation ducts 2 corresponding to ventilation area A are A1, A2, A3, A4, A5, etc., and the preset numbers of the multiple ventilation ducts 2 corresponding to ventilation area B are B1, B2, B3, B4, B5, etc.

[0134] S230: Connect the pre-numbered ventilation pipe 2 to the air source 40.

[0135] Taking ventilation area A as an example: the ventilation area information is obtained as ventilation area A according to the ventilation mode. The preset number of the ventilation pipe 2 corresponding to the ventilation area information is A. Then, one or more ventilation pipes 2 with preset number A are connected to the air source 40. For example, the ventilation pipes 2 with preset numbers A1 and A2 are connected to the air source 40, or the ventilation pipes 2 with preset numbers A1 and A5 are connected to the air source 40, thereby realizing ventilation in ventilation area A.

[0136] When the ventilation mode includes ventilation intensity information, please refer to ​ Step S200 includes:

[0137] S240: Obtain ventilation intensity information based on the ventilation mode.

[0138] Ventilation intensity information can include light breeze, moderate wind, and strong wind.

[0139] S250: The preset number of ventilation ducts 2 corresponding to the ventilation intensity information is obtained.

[0140] The preset number of ventilation ducts 2 corresponding to a light breeze is the first number, the preset number of ventilation ducts 2 corresponding to a moderate stroke is the second number, and the preset number of ventilation ducts 2 corresponding to a strong wind is the third number. Among them, the third number is greater than the second number, and the second number is greater than the first number, so the ventilation intensity of a strong wind is greater than the ventilation intensity of a moderate stroke, and the ventilation intensity of a moderate stroke is greater than the ventilation intensity of a light breeze.

[0141] S260: Controls a preset number of ventilation pipes 2 to connect to the air source 40.

[0142] Taking ventilation intensity information including light breeze, medium breeze and strong breeze as an example: the preset numbers of multiple ventilation ducts 2 are 1, 2, 3, 4, 5, 6, etc.

[0143] When the ventilation intensity information of the ventilation mode is light, a first number of ventilation pipes 2 can be connected to the air source 40. The first number can be one-third of the total number of ventilation pipes 2. For example, controlling the ventilation pipes 2 with preset numbers 1 and 2 to connect to the air source 40, or controlling the ventilation pipes 2 with preset numbers 2 and 5 to connect to the air source 40, so as to achieve ventilation with a light breeze intensity.

[0144] When the ventilation intensity information of the ventilation mode is moderate, a second number of ventilation pipes 2 can be connected to the air source 40. The second number can be two-thirds of the total number of ventilation pipes 2. For example, controlling the ventilation pipes 2 with preset numbers 1, 2, 3, and 4 to connect to the air source 40, or controlling the ventilation pipes 2 with preset numbers 2, 3, 4, and 5 to connect to the air source 40, so as to achieve ventilation intensity of moderate.

[0145] When the ventilation intensity information of the ventilation mode is high wind, a third number of ventilation pipes 2 can be connected to the air source 40. The third number can be equal to the total number of ventilation pipes 2. For example, ventilation pipes 2 with preset numbers 1, 2, 3, 4, 5, and 6 can be connected to the air source 40 to achieve ventilation intensity of high wind.

[0146] When the ventilation mode includes ventilation area information and ventilation intensity information, please refer to ​ Step S200 includes:

[0147] S210: Obtain ventilation area information based on ventilation mode.

[0148] S220: Obtain the preset number of ventilation duct 2 corresponding to the ventilation area information based on the ventilation area information.

[0149] S240: Obtain ventilation intensity information based on the ventilation mode.

[0150] S250: The preset number of ventilation ducts 2 corresponding to the ventilation intensity information is obtained.

[0151] Steps S210, S220, S240, and S250 are the same as the steps with the same names mentioned above, and will not be repeated here.

[0152] S270: Control the ventilation pipes 2 with preset numbers, and connect a preset number of ventilation pipes 2 to the air source 40.

[0153] Taking ventilation area A as an example, and ventilation intensity information including light breeze, medium breeze and strong breeze: the preset numbers of the multiple ventilation pipes 2 corresponding to ventilation area A are A1, A2, A3, A4, A5, A6, etc.

[0154] When the ventilation intensity information of the ventilation mode is "light breeze", the first number of ventilation pipes 2 with preset number A can be connected to the air source 40. The first number can be one-third of the number of ventilation pipes 2 with preset number A. For example, the ventilation pipes 2 with preset numbers A1 and A2 can be connected to the air source 40, or the ventilation pipes 2 with preset numbers A2 and A5 can be connected to the air source 40, so as to achieve ventilation with a light breeze intensity in the ventilation area A.

[0155] When the ventilation intensity information of the ventilation mode is moderate, the second number of ventilation pipes 2 in the preset number A can be connected to the air source 40. The second number can be two-thirds of the number of ventilation pipes 2 in the preset number A. For example, the ventilation pipes 2 in the preset number A1, A2, A3, and A4 can be connected to the air source 40, or the ventilation pipes 2 in the preset number A2, A3, A4, and A5 can be connected to the air source 40 to achieve ventilation intensity of moderate at ventilation area A.

[0156] When the ventilation intensity information of the ventilation mode is high wind, the third number of ventilation pipes 2 in the preset number A can be connected to the air source 40. The third number can be equal to the number of ventilation pipes 2 in the preset number A. For example, the ventilation pipes 2 in the preset numbers A1, A2, A3, A4, A5, and A6 can be connected to the air source 40 to achieve ventilation intensity of high wind at the ventilation area A.

[0157] The temperature control system 100, seat 1000, and temperature control method of this application embodiment utilize the vortex tube 301 in the temperature control system 1000. The vortex tube 301 is a device that uses compressed air to generate cold and hot effects. It can separate the input compressed air into two airflows, cold and hot. By adjusting the flow ratio of the cold and hot airflows, precise temperature control can be achieved. In this application embodiment, when cold and hot airflows are introduced into the air bag assembly 302 through the vortex tube 301, the temperature of the air bag assembly 302 is adjusted, thereby regulating the temperature of the seat 1000 and improving the comfort of the user sitting in the seat 1000.

[0158] Furthermore, compared to traditional methods of temperature regulation using heating wires or water circulation, the temperature control system 100 provided in this embodiment uses a vortex tube 301, which offers advantages such as simple structure, convenient maintenance, low energy consumption, fast response speed, and high temperature regulation accuracy. Simultaneously, the vortex tube 301 eliminates the need for water or other liquid media, avoiding potential risks such as water leakage and improving the safety and reliability of the temperature control system 100.

[0159] In addition, by setting up the ventilation device 10, the ventilation device 10 and the temperature control component 30 share the air source 40, that is, it is not necessary to set up separate air sources 40 for the ventilation device 10 and the temperature control component 30, which can improve the compactness of the temperature control system 100 structure and reduce costs.

[0160] Furthermore, in the ventilation device 10, when the air source 40 introduces gas into the duct 24 and sprays it from the contraction section 21 towards the expansion section 23, a negative pressure can be generated in the contraction section 21 to draw in more gas. This small airflow drives a large airflow, which enhances the heat dissipation effect and efficiency of the seat 1000, allowing the seat 1000 to cool down quickly. Simultaneously, by using a small airflow to drive a large airflow, the ventilation device 20 can also quickly remove moisture generated by sweat. Combined with the temperature control component 30's adjustment of the seat 1000's temperature, the seat 1000 can quickly reach suitable temperature and humidity conditions, improving the user experience. The air source 40 and controller do not need to be located inside the seat 1000, which helps reduce the size and noise of the seat 1000. The ventilation pad 1 is flat, which helps reduce its impact on the dimensions of the seat 1000. The temperature control method of this embodiment, based on the seat 1000, can achieve controllable ventilation area and intensity according to user needs, thus improving user comfort.
