Description

Technical Field

[0001] The present invention is a temperature control seat cushion, and particularly refers to a temperature control seat cushion that can assist in regulating the body temperature of infants and young children.

Background Art

[0002] Generally, a common baby stroller provides a good supporting effect by installing a seat cushion inside, enabling infants and young children to be placed on the stroller more comfortably. However, the body temperature regulation system of infants and young children has not yet fully developed and is quite sensitive to temperature changes in the environment. Therefore, in an outdoor environment, the heat between the body of an infant and young child and the seat cushion is difficult to dissipate, which may lead to excessive sweating and even health risks such as heatstroke.

[0003] In order to avoid the problem that heat is difficult to dissipate when an infant and young child sits on the seat cushion, currently, a heat dissipation seat cushion is sold in the market. In this heat dissipation seat cushion, a mist device and a fan are installed at the lower position of the seat cushion body. The mist device can generate mist, and the fan operates to introduce external air, form an air current, and blow the mist onto the seating part of the seat cushion body, thereby providing a heat dissipation function.

[0004] However, the mist device and the fan of the current heat dissipation seat cushion are individually and dispersedly installed inside the seat cushion body. Moreover, since it is necessary to arrange a water supply pipe for the mist device inside the seat cushion body, not only does the cost required for manufacturing and piping increase, but there is also a risk that the water supply pipe arranged inside the seat cushion body is likely to be damaged due to long-term use.

[0005] Furthermore, the airflow blown in by the fan of existing heat-dissipating seat cushions can only enter the seat portion of the cushion itself, providing only heat dissipation to the area around the infant's buttocks, while the heat from the back remains difficult to dissipate. In other words, the applicant of this invention is focusing its research efforts on how to reliably assist in regulating the body temperature of infants. [Overview of the project] [Problems that the invention aims to solve]

[0006] The main objective of this invention is to improve upon the problems of existing heat dissipation sheet cushions, such as the high cost required for manufacturing and piping, the risk of damage to internal water supply pipes, and the limitations of heat dissipation effectiveness, by providing a temperature-controlled sheet cushion. [Means for solving the problem]

[Modes for carrying out the invention]

[0009] As described in the summary of the invention, the temperature-controlled seat cushion of the present invention includes a temperature control device 1, and a preferred embodiment of the temperature control device 1, referring to Figures 1 and 2, includes a housing 10, a mist assembly 11, and a fan 12.

[0010] As shown in Figure 1, the housing 10 has an exhaust port 101 and at least one intake port 102.

[0011] As shown in Figures 1 and 2, the mist assembly 11 is installed in the housing 10 and can generate mist and send it to the exhaust port 101. In a preferred embodiment of the temperature control device 1, the mist assembly 11 includes a water tank 111 and a misting device 112, the water tank 111 is capable of holding water inside and has a filling port 113 formed on one side of the water tank 111, the misting device 112 is connected to the water tank 111 and can introduce water from the water tank 111, atomize it, generate mist and send it to the exhaust port 101.

[0012] As shown in FIGS. 1 and 2, the fan 12 is installed in the housing 10 and communicates with the air inlet 102. The air at the air inlet 102 can be introduced to form an air flow, and the mist can be sent out from the exhaust port 101 by the air flow. Among them, in a preferred embodiment of the temperature control device 1, the fan 12 has a delivery port 121 whose opening faces the exhaust port 101 of the housing 10. The temperature control device 1 is installed in the housing 10 and includes a heating unit 13 located at the delivery port 121 of the fan 12.

[0013] Among them, since the mist assembly 11 and the fan 12 of the temperature control device 1 are installed in the housing 10 and a modular structural design is adopted, the piping cost can be significantly reduced, and at the same time, the risk of the pipeline bursting can also be reduced.

[0014] Also, as shown in FIGS. 2 and 9, the temperature control device 1 can also increase the temperature of the air flow blown out from the fan 12 through the heating unit 13 to provide a heat preservation effect. Therefore, the temperature control device 1 can assist in the body temperature regulation of infants and toddlers, and the user can also switch and use the cooling or heat preservation function according to the environmental temperature situation.

[0015] Furthermore, referring to FIGS. 3 to 5, these are preferred embodiments of the temperature control seat cushion of the present invention, and include a seat cushion body 20, the two aforementioned temperature control devices 1, a bottom-mounted blower 30, and a control device 40.

[0016] As shown in FIGS. 3 and 4, a breathable fabric material is adopted for the seat cushion body 20. The seat cushion body 20 has a head pad portion 21, a back pad portion 22, a seat portion 23, and a foot pad portion 24 connected in sequence from top to bottom. The back pad portion 22 includes a back pad area 221 and assembly areas 222 respectively located on both left and right sides of the back pad area 221. The above assembly areas 222 and the above foot pad portion 24 respectively form at least one air intake opening 223, 241.

[0017] As shown in FIGS. 3 to 5, the two temperature control devices 1 are installed in the seat cushion body 20, and each is located within the assembly region 222 of the back pad portion 22. The positions of the air inlets 102 of the two temperature control devices 1 respectively correspond to the air intake openings 223 of the above-mentioned assembly region 222, and the exhaust ports 101 of the two temperature control devices 1 respectively face the back pad region 221.

[0018] As shown in FIGS. 3 to 5, the bottom-mounted blower 30 is installed in the foot pad portion 24 of the seat cushion body 20 and is adjacent to the air intake opening 241 of the foot pad portion 24. The bottom-mounted blower 30 can introduce the air at the air intake opening 241 of the foot pad portion 24 and blow the air flow in the direction of the seat portion 23.

[0019] As shown in FIGS. 5 and 10 to 12, the control device 40 is installed on the bottom-mounted blower 30, is electrically connected to the two temperature control devices 1 and the bottom-mounted blower 30 to control them, and can provide an operating power source for the two temperature control devices 1 and the bottom-mounted blower 30.

[0020] As shown in Figure 6, the temperature-controlled seat cushion of the present invention can be applied to strollers 70 and baby beds, and can be used to seat or lay infants. As shown in Figure 7, the two temperature control devices 1 release mist from the mist assembly 11, and at the same time, combine it with the blowing of air from the fan 12 to thoroughly mix the mist and airflow, and then release it from the surface of the back pad portion 22 of the seat cushion body 20 to evaporate, thereby providing a uniform cooling effect on the back of the infant. Furthermore, as shown in Figure 8, the bottom-mounted blower 30 of the temperature-controlled seat cushion introduces air from the intake opening 241 of the foot pad portion 24 and blows airflow toward the seat portion 23, thereby also providing a heat dissipation function for the seat portion 23. As a result, the temperature-controlled seat cushion provides cooling and heat dissipation functions to the back pad portion 22 and seat portion 23 of the seat cushion body 20 through the two temperature control devices 1 and the bottom-mounted blower 30, assisting in the regulation of the infant's body temperature and providing a comfortable resting environment for the infant.

[0021] During operation of the temperature control device 1, the device temporarily stops the operation of the mist assembly 11 after spraying mist for a certain period of time, and continuously blows air through the fan 12, thereby maintaining the seat cushion body 20 in an appropriate humidity environment.

[0022] As shown in Figures 5 and 10, in a first preferred embodiment of the temperature-controlled seat cushion of the present invention, the control device 40 includes a controller 41, of which the controller 41 is electrically connected to a power supply 42, the power supply 42 may be, for example, a built-in battery, a replaceable battery, or an external mobile power supply, the temperature-controlled seat cushion includes at least one temperature sensor 50, the at least one temperature sensor 50 is installed in the seat cushion body 20, the controller 41 is electrically connected to the at least one temperature sensor 50, the controller 41 controls the operation of the two temperature control devices 1 and the bottom-mounted blower 30 based on at least one temperature threshold and the temperature signal St of at least one temperature sensor 50, of which the at least one temperature threshold is an adjustable preset value of the controller 41, and the at least one temperature threshold may be one or more. In an embodiment where there is one temperature threshold, if the temperature signal St is equal to or greater than the temperature threshold, the controller 41 can start the operation of the two temperature control devices 1 and the bottom-mounted blower 30, and if the temperature signal St is less than the temperature threshold, the controller 41 can control the two temperature control devices 1 and the bottom-mounted blower 30 to stop their operation. In an embodiment where there are multiple temperature thresholds, for example, there may be a first temperature threshold and a second temperature threshold that is greater than the first temperature threshold, and if the temperature signal St is less than the first temperature threshold, the controller 41 can control the two temperature control devices 1 and the bottom-mounted blower 30 to stop their operation, and if the temperature signal St is equal to or greater than the first temperature threshold and less than the second temperature threshold, the controller 41 can start the operation of the two temperature control devices 1 and the bottom-mounted blower 30, and if the temperature signal St is greater than the second temperature threshold, the controller 41 can increase the driving efficiency of the two temperature control devices 1 and the bottom-mounted blower 30. In this way, by adjusting the airflow of the two temperature control devices 1 and the bottom-mounted blower 30, as well as the amount of mist from the two temperature control devices 1, based on the ambient temperature, the cooling efficiency can be increased.This allows the seat cushion body 20 of the temperature-regulating seat cushion to be kept within an appropriate temperature range, assisting in the regulation of the infant's body temperature and providing a comfortable resting environment for the infant.

[0023] As shown in Figures 5 and 11, in a second preferred embodiment of the temperature-controlled seat cushion of the present invention, the control device 40 includes a controller 41 and a wireless transceiver 43, the controller 41 is electrically connected to a power supply 42 and the wireless transceiver 43, the power supply 42 may be, for example, a built-in battery, a replaceable battery or an external mobile power supply, the wireless transceiver 43 may be, for example, a WiFi communication circuit module or a Bluetooth® communication circuit module, and the controller 41 is connected to a mobile device 60 via the wireless transceiver 43. The system continues to operate, and the user can operate the mobile device 60 to cause the controller 41 to receive a control command S1 from the mobile device 60 via the wireless transceiver 43, and control the operation and driving efficiency of the two temperature control devices 1 and the bottom-mounted blower 30 based on the control command S1. In this way, the user can adjust and control the airflow of the two temperature control devices 1 and the bottom-mounted blower 30, the amount of mist generated by the mist assembly 11 of the two temperature control devices 1, and whether or not the heating unit 13 is operating, according to the user's needs.

[0024] Furthermore, as shown in Figures 5 and 12, in a third preferred embodiment of the temperature-controlled seat cushion of the present invention, the control device 40 includes a controller 41 and a wireless transceiver 43, the controller 41 is electrically connected to a power supply 42 and the wireless transceiver 43, the power supply 42 may be, for example, a built-in battery, a replaceable battery, or an external mobile power supply, the wireless transceiver 43 may be, for example, a WiFi communication circuit module or a Bluetooth® communication circuit module, the temperature-controlled seat cushion includes at least one temperature sensor 50, the at least one temperature sensor 50 is installed in the seat cushion body 20 and is electrically connected to the controller 41, the controller 41 is connected to a mobile device 60 via the wireless transceiver 43, the controller 41 receives at least one temperature signal St from the at least one temperature sensor 50, generates corresponding temperature information T based on the at least one temperature signal St, and transmits the temperature information T to the mobile device 60 via the wireless transceiver 43. Furthermore, the mobile device 60 can output a switching command S2 to the controller 41, and the controller 41 executes automatic mode and manual mode based on the switching command S2.

[0025] In automatic mode, the controller 41 receives a temperature signal St from at least one temperature sensor 50 and controls the operation of the two temperature control devices 1 and the bottom-mounted blower 30 based on at least one temperature threshold and the temperature signal St from at least one temperature sensor 50. The operating principle can be found in the first preferred embodiment and will not be described in detail again here.

[0026] In manual mode, the user can operate the mobile device 60 to cause the controller 41 to receive a control command S1 from the mobile device 60 via the wireless transceiver 43, and to control the operation and driving efficiency of the two temperature control devices 1 and the bottom-mounted blower 30 based on the control command S1. This allows the user to adjust and control the airflow of the two temperature control devices 1 and the bottom-mounted blower 30, the amount of mist generated by the mist assembly 11 of the two temperature control devices 1, and whether or not the heating unit 13 is operating, according to their needs.

[0027] Furthermore, as shown in Figure 13, in one embodiment, the power supply 42 is electrically connected to the heating unit 13, the control device 40 includes an electronic switch SW, which may be, for example, a transistor, and the electronic switch SW can be connected in series to the connection path between the power supply 42 and the heating unit 13, and the controller 41 is electrically connected to the electronic switch SW to control the on and off of the electronic switch SW. For example, the heating unit 13 may be a heating wire, and when the controller 41 controls the electronic switch SW to turn it on, the heating wire can receive current from the power supply 42 and generate heat, and when the controller 41 controls the electronic switch SW to turn it off, the heating wire cannot receive current from the power supply 42 and therefore does not generate heat. The controller 41 stores a threshold lower limit, which is an adjustable preset value of the controller 41, and the threshold lower limit is below the aforementioned at least one temperature threshold. As shown in Figures 5 and 9, in automatic mode, when the controller 41 determines that the temperature signal St is lower than the lower threshold, the controller 41 controls and activates the heating units 13 (heating wires) of the two temperature control devices 1 to perform heating. In other words, when the controller 41 controls and turns on the electronic switch SW, it simultaneously activates the fan 12 to blow out warm air, thereby raising the temperature of the back pad area 221 of the seat cushion body 20 and assisting in the regulation of the infant's body temperature, preventing the infant from catching a cold due to catching a cold in a low-temperature environment.

[0028] As described above, the temperature control device 1 in the temperature-controlled seat cushion of this invention significantly reduces piping costs and the risk of pipe rupture through its modular structural design. The temperature-controlled seat cushion of this invention, through the combination of the two temperature control devices 1 and the bottom-mounted blower 30, provides excellent cooling and heat dissipation effects to the back pad portion 22 and the seat portion 23 of the seat cushion body 20, respectively, or provides a heat retention effect through the combination of the heating unit 13 and the fan 12 of the temperature control device 1. As a result, the temperature-controlled seat cushion can assist in regulating the body temperature of infants and toddlers, whether in scorching heat or cold environments, and provide infants and toddlers with a comfortable resting environment.
