Description

The present invention relates to the technical fields of home and medical assistive devices, and particularly to electronic temperature lowering devices.

Fever in children is a frequent illness, and it is suggested to clinically employ physical hypothermia when body temperature is below 39 ° C. In particular, when the body temperature exceeds 39 ° C, the child's body has not yet fully developed, resulting in maximum damage to the cerebrum, which in turn causes cerebral dysfunction, causing symptoms such as loss of consciousness and generalized convulsions. It is easy and medically called febrile convulsions. If the number of convulsions is too high without care, brain cell damage will occur, affecting the development of intelligence. Due to the various flaws in conventional physical cooling methods such as cooling sheets, ice bags, wet towels, alcohol wipes, etc., the market demands safe, effective, lightweight and portable heating devices.

In the prior art, the cooling structure of a temperature lowering device product using a semiconductor cooling plate as a cooling member is mainly composed of the following members and the like.

a. A semiconductor cooling plate configured to generate a cold source, one side to cool and the other to heat.
b. A heat dissipation sheet that is configured to expand the heat dissipation area.
c. A fan configured to enhance ventilation, produce continuous air convection, and circulate and dissipate heat.
d. A cold conductive metal plate configured to transmit the cold source of the cooling surface of the cooling plate to a cold conductive medium.
e. Cold conductive medium.
Since the cold conductive metal plate connected to the semiconductor cooling plate cannot uniformly transmit the cold source, a cold conductive medium such as a water bag or a water bag is used so as to reduce the amount of cold lost during the transmission. It is necessary to uniformly transmit the non-uniform cold source in the cold conductive metal plate.

In the above technical proposal, the shape of the temperature lowering device (particularly the shape of the cold conduction module) is fixed and cannot be deformed, and can be adhered only to the shape of the forehead of one type of human body, which is not versatile and has a low degree of adhesion. There is a flaw in the low comfort. If the adhesion is incomplete, the cold transfer area becomes small, the temperature lowering efficiency is low, and if the local temperature is too low, the amount of cold wear increases and the power consumption increases, so that the temperature lowering action can be performed well. Not only can it not be done, but it also consumes a lot of power and is expensive to manufacture.

Therefore, improvement of versatility, adhesion and comfort of the temperature lowering device is now a technical problem to be solved immediately by those skilled in the art.

In view of this, an object of the present invention is to use a metal braided band as a flexible cold conductive material instead of the metal cold conductive plate in the prior art, to be able to adhere to differently shaped foreheads and to adapt at low cost. In addition, it is to provide an electronic temperature lowering device having high versatility, adhesion and comfort.

In the electronic temperature lowering device according to the embodiment of the present invention, the cold source of the cooling surface of the cooling plate 6 is transmitted to the cold conduction medium 123 by the metal braided band 122. Here, the metal braided band 122 is a flexible band formed by a plurality of metal wires. Here, the fact that the metal braided band 122 is knitted with a plurality of metal wires means that the metal braided band 122 may be knitted by hand or by a device. Not particularly limited.

As can be seen from the above technical proposal, in the electronic temperature lowering device according to the embodiment of the present invention, the metal braided band 122 is used as the flexible cold conductive material instead of the metal cold conductive plate in the prior art, that is, the metal braided band. The cold source of the cooling surface of the cooling plate 6 is transmitted to the cold conductive medium 123 by the 122. Since the metal braided band 122 is woven or woven, it has a certain degree of flexibility, can be bent and deformed, and can be closely adapted to differently shaped foreheads, and its versatility. Both adhesion and comfort were effectively improved. Further, when the degree of adhesion is high, the problem that the partial temperature is too low and the amount of cold consumption is large does not occur, which contributes to improvement of heat transfer efficiency and energy saving. Also, the cost of the metal braided band 122 is lower than that of the cold conductive metal plate in the prior art.

The basic operating principle of the electronic temperature lowering device according to the embodiment of the present invention is that when the cooling plate 6 is energized, the amount of cold generated is transmitted to the metal braided band 122, transmitted to the cold conduction medium 123, and also. It is transmitted to the human epidermis. Since the temperature of the human body is higher than the temperature of the cold conductive medium 123, the purpose of lowering the temperature of the human body is achieved by performing heat exchange between the human body epidermis and the cold conductive medium 123 based on the heat transfer principle. Further, mainly by the heat radiating fan 3 and the heat radiating sheet 4, the amount of heat generated on the other surface of the cooling plate 6 is forcibly transferred to the air, and the whole process continues to circulate, thereby reaching a certain temperature lowering effect.

In a specific embodiment, the metal wire used for the metal braided band 122 is made of an aluminum material. However, the present invention is not limited to this, and other metal materials (for example, steel wire, copper wire, etc.) may be adopted, but aluminum wire is lightweight and has excellent cold conduction performance among these metal materials. Therefore, manufacturing the metal braided band 122 with an aluminum wire is a preferable form to be protected of the present invention.

Here, the wire diameter of the metal wire made of aluminum is a common specification, and in the manufacturing process, there is generally a requirement for the number of metal wires, and there are various methods for knitting aluminum. Does not make a specific request here.

In a specific embodiment, as shown in FIGS. 3 and 4, the cold conduction module 12 in the electronic temperature lowering device specifically includes a blanket 121, a metal braided band 122, a cold conduction medium 123, and a thin film 124. Here, the brushed cloth 121 is located near the cooling plate 6 of the metal braided band 122, is fixedly connected to the metal braided band 122, and the cold conductive medium 123 is located near the forehead of the human body of the metal braided band 122. , Covered with a thin film 124, stylized, and fixedly connected to a metal braided band 122.

In the electronic temperature lowering device in the prior art, since the amount of cold transmitted by the cold-conducting metal plate is non-uniform, it is necessary to add another cold-conducting medium to uniformly conduct the amount of cold to the human epidermis. The medium is generally a water bag. However, evenly transmitting the cold source to the human skin with a water bag is a relatively complicated manufacturing process, has low thermal efficiency (effective heat exchange level acting on the human body), and is a cold source consumed for transmission. Is relatively large, power consumption is large, continuation capacity is weak, it is necessary to supply power using a dedicated battery or power adapter, the cruising capacity is only 1 to 2 hours (input power 9V to 2A), and the usage time is short. If you try to increase the cruising time, the volume of the battery will double and the burden of carrying will increase.

Regarding the above problems, the present invention uses a hydrogel material as the cold conduction medium 123, uniformly transmits the cold source to the human epidermis, has a high rate of cold conduction, relatively high thermal efficiency, reduces cold loss, and consumes power. To reduce. As a result, it is possible to use a mobile power supply with 5V to 1A output of a normal USB interface (input power is 5W, the energy acting on the human body is slightly attenuated), making it easier and more flexible to use, and the same. Under the condition of electric energy, the cruising time is 4 hours, the usage time is increased by about 3 hours compared to the conventional technical proposal, the mobile power supply can be easily replaced, and a longer usage time can be obtained.

Further, in a specific example, the thin film 124 is a PU thin film or a TPU thin film. Here, the blanket 121 and the thin film 124 perform sealing and sealing functions in order to prevent water evaporation of the gel material. However, the present invention is not particularly limited to this, and in the cold conduction module, another soft and gas-impermeable material may be used as the sealing layer, and the present invention is not particularly limited to this.

Specifically, the edge of the metal braided band 122 is pressed to a fixed size by a die, then covered with a blanket 121, a hydrogel material and a thin film 124, and thermocompression bonded by a thermocompression bonding device. , Achieve the purpose of encapsulation. The cold conduction module 12 thus manufactured has a good effect of cold transfer, is also very soft and comfortable, and can adapt to different head shapes.

Further, in a specific embodiment, the electronic temperature lowering device is further provided with a base 8. Here, as shown in FIGS. 3 and 4, in the cold conduction module 12, a relief hole (preferably a square hole) is provided at a position corresponding to the cooling plate 6 on the raised cloth 121, and the cooling plate in the metal braided band 122 is provided. A copper piece (preferably a square copper piece) is provided at a position corresponding to No. 6, a screw penetrates the copper piece and the escape hole, and the copper piece and the base 8 are fixedly connected. As can be seen from this, the reason why the escape hole is provided in the center of the brushed cloth 121 is that the cooling plate 6 and the copper piece are in direct contact with each other and play a role of escape. Since the material of the metal braided band is soft and the screws cannot be tightened directly to the metal braided band, a copper piece is provided on the metal braided band 122, and its role is to tighten and fix the cold conduction module 12 and the base 8. Is.

Further, as shown in FIGS. 3 and 5, in the electronic temperature lowering device, the PCB (Printed Circuit Board) substrate group 7, the cooling plate 6, the heat radiating sheet 4, and the heat radiating fan 3 are mounted inside the base 8, respectively. The button 9 is attached to the outside of the base, the headband 10 is attached to both ends of the base 8 by the headband ridges 11, mounting holes are provided at the bottom of the base 8, and the cooling plate 6 is located inside the mounting holes. And in contact with the cold conduction module, the cooling plate 6 is a semiconductor cooling plate. Here, the electric energy of the cooling plate 6 and the heat radiating fan 3 is supplied from the mobile power source.

In the prior art, an aluminum profile is used as a heat radiating sheet, the heat radiating surface area of a unit volume is limited due to process restrictions, and the fixing method with the heat radiating fan is superposition. The volume is large, the mass is heavy, and it is difficult to install. In a specific embodiment of the present invention, the heat-dissipating sheet 4 adopted is a toothed heat-dissipating sheet, which is formed by integrally processing, and the thickness of each single heat-dissipating sheet in the entire heat-dissipating sheet 4 is increased. It is thin, and the heat dissipation area of a unit volume in the entire heat dissipation sheet 4 becomes larger. Therefore, as compared with the prior art, the toothed heat radiating sheet according to the specific embodiment of the present invention can achieve the same heat radiating area with a smaller volume and occupies a smaller space. Alternatively, although the volume of the heat radiating sheet is the same, the heat radiating area is larger, and the heat radiating effect is effectively improved.

Further, in a specific embodiment of the present invention, the heat dissipation fan 3 adopted is a frameless fan (that is, a fan from which the outer frame of the heat dissipation fan in the prior art is removed), and the frameless fan 3 has toothed heat dissipation. It is arranged on the sheet, that is, as shown in FIGS. 9 and 10, a mounting space for arranging the frameless fan 3 is provided at the center of the toothed heat radiating sheet, and a plurality of both ends of the toothed heat radiating sheet are provided. It is a single heat-dissipating sheet, which can increase the heat-dissipating area, form a heat-dissipating passage, effectively improve heat-dissipating efficiency, and reduce the volume and weight of the heat-dissipating module. As can be seen from this, by combining the frameless fan 3 and the heat-dissipating sheet with ultra-thin teeth with an arrangement structure in which the fan is built-in, the layout space of the heat-dissipating module can be made more rational, and the product It is possible to reduce the size and thickness and improve the wearability.

Further, as shown in FIGS. 3 and 5, the electronic temperature lowering device further includes a mesh cover 1, a dustproof net frame 2, a screen, and a baffle 5. Here, the mesh cover 1 is provided with an intake hole at a position corresponding to the heat dissipation fan, an exhaust hole is provided at a position corresponding to the heat dissipation sheet 4, both ends of the mesh cover 1 are connected to the base 8, respectively, and a dustproof net is provided. The frame 2 is located between the inner surface of the mesh cover 1 and the base 5, and the dustproof net frame 2 has a frame structure (particularly, the position corresponding to the ventilation hole in the mesh cover 1 is the frame structure), and the screen is the screen. The screen is provided with dustproof holes having a hole diameter smaller than the hole diameters of the ventilation holes (intake holes and exhaust holes) in the mesh cover 1 provided in the frame structure, and the baffle 5 is provided inside the mesh cover 1 with the intake holes. It is located between the exhaust hole and prevents hot air from returning to the intake hole. Specifically, the screen is knitted with nylon yarn to form a 300 mesh nylon mesh, hair cannot pass through the dustproof holes on the screen, and the dustproof net frame 2 is injection-molded together with the screen. Moreover, since the mesh cover 1 is generally a metal mesh cover and it is not possible to realize the installation of a hole diameter that is too small in the through-hole process, the dustproof effect is achieved by providing the dustproof net frame 2 with a screen.

From the above, the basic roles of each component in the electronic temperature lowering device according to the specific embodiment of the present invention are as follows.
