The low-voltage direct current heating wearable devices (such as clothes, waistbands, trousers, hats and insoles) in the market at present mainly comprise a power supply, a controller and a heating plate.
The existing low-voltage direct-current heating wearable device is generally not provided with a safety device capable of automatically regulating and controlling the temperature, so that a user is easy to suffer from cold and scald when the device is used for a long time, and certain injury is caused to the user. Cold-scalding refers to the condition that a long-term contact with an object at about 50-60 ℃ such as a heating pad or the like causes scalding, and sometimes the condition that human feet are scalded into water bubbles by a hot water bag at night in winter is the same.
Disclosure of Invention
Accordingly, the present invention is directed to overcome the shortcomings of the prior art, and provides a low-voltage dc heating wearable device safety protection device capable of preventing cold and scald.
The technical scheme adopted for solving the technical problems is as follows: the low-voltage direct-current heating wearable device safety protection device comprises a mobile power supply, a main control device IC, a cold-scalding protection device, a temperature control device and a carbon fiber heating patch; the mobile power supply is connected with the main control device IC to provide electric energy; the temperature control device is connected with the cold injury protection device in parallel and then is respectively connected with the main control device IC and the carbon fiber heating patch.
Furthermore, in order to improve cold-scalding prevention precision, the cold-scalding protection device comprises a normally closed high-sensitivity vibration sensor which is connected with the temperature control device in parallel.
Further, in order to prevent the carbon fiber heating patch from being too high in temperature and causing high-temperature scalding, the temperature control device is connected with the carbon fiber heating patch through the overheat protector after being connected with the normally-closed high-sensitivity vibration sensor in parallel.
In order to conveniently display the heating condition of the carbon fiber heating patch, an indicator lamp connected in parallel with the normally-closed high-sensitivity vibration sensor is further arranged between the main control device IC and the carbon fiber heating patch.
In order to improve dustproof, waterproof and oxidation resistance, the sensing surface of the normally closed high-sensitivity vibration sensor is thickened and plated with gold.
In order to further improve the dustproof, waterproof and antioxidant capacities, the purity of the electro-gold plating is 99.00% -99.99%.
In order to further improve the dustproof, waterproof and antioxidant capacity, the purity of the electro-gold plating is 99.50-99.99%.
Further, the purity of the electro-gold plating is 99.97%.
In order to reduce the weight and facilitate carrying, the mobile power supply is a lithium ion storage battery.
In order to improve the safety performance of the carbon fiber heating patch, the outer part of the carbon fiber heating patch is sleeved with a non-woven fabric layer.
The beneficial effects of the invention are as follows: according to the safety protection device for the low-voltage direct-current heating wearable device, the working state of the carbon fiber heating patch can be conveniently controlled through the cooperation of the mobile power supply, the main control device IC, the cold-scalding protection device, the temperature control device, the carbon fiber heating patch and the like, so that the occurrence of cold-scalding is prevented, and the safety performance is improved. Because the cold-scalding protection device comprises the normally-closed high-sensitivity vibration sensor, the normally-closed high-sensitivity vibration sensor is connected with the temperature control device in parallel, and the cold-scalding protection precision is improved. Because the temperature control device is connected with the carbon fiber heating patch through the overheat protector after being connected with the normally-closed high-sensitivity vibration sensor 60 in parallel, the high-temperature scald caused by overhigh temperature of the carbon fiber heating patch is prevented. Because the main control device IC and the carbon fiber heating patch are also provided with the indicator lamp connected with the normally-closed high-sensitivity vibration sensor in parallel, the heating condition of the carbon fiber heating patch is conveniently displayed. Because the sensing surface of the normally-closed high-sensitivity vibration sensor is thickened, and gold is plated, the dustproof, waterproof and oxidation-resistant capacities are improved, and the service life is prolonged. The purity of the electro-gold plating is 99.00% -99.99%, so that the dustproof, waterproof and oxidation-proof capabilities are further improved. Because the mobile power supply is a lithium ion storage battery, the weight is reduced, and the portable power supply is convenient to carry.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
As shown in fig. 1, the invention provides a low-voltage direct-current heating wearable device safety protection device, which comprises a mobile power supply 10, a main control device IC, a cold-ironing protection device, a temperature control device 20 and a carbon fiber heating patch 30; the mobile power supply 10 is connected with the main control device IC to supply electric energy; the temperature control device 20 is connected with the main control device IC and the carbon fiber heating patch 30 after being connected with the cold injury protection device in parallel. According to the low-voltage direct-current heating wearable device safety protection device, the working state of the carbon fiber heating patch 30 can be conveniently controlled through the cooperation of the mobile power supply 10, the main control device IC, the cold burn protection device, the temperature control device 20, the carbon fiber heating patch 30 and the like, so that the occurrence of cold burn is prevented, and the safety performance is improved. Taking clothes as an example, when the carbon fiber heating patch 30 is installed at a position in the clothes, which needs to be heated, other components such as the mobile power supply 10, the main control device IC, the temperature control device 20 and the cold injury protection device can be installed at random positions of the clothes, and the carbon fiber heating patch 30 can be uniformly distributed around the periphery of the carbon fiber heating patch 30 based on the convenience of wearing. When the portable power source 10 provides electric energy in use, the main control device IC controls the temperature control device 20 to adjust the temperature, the carbon fiber heating patch 30 heats and heats, and the cold-scalding protection device mainly aims at preventing local tissue injury, namely cold-scalding caused by contact of the carbon fiber heating patch 30 under a long-time static state. The main mode is to transmit signals to the main control device IC, so that the main control device IC commands the temperature control device 20 to cool down, and the main control device IC can be implemented by a timing switch, a pressure sensor, a vibration sensor or the like.
The cold-scalding protection device can be realized by a timing switch, a pressure sensor or a vibration sensor. If the timing switch is adopted, the user can be triggered in the moving process, and the user can not keep warm if the temperature is lowered by triggering; if a pressure sensor is used, the user may trigger when wearing things or other actions, so that the user cannot keep warm, which is contrary to the original purpose of setting the low-voltage direct-current heating wearable device, so that the cold-scalding protection device preferably comprises a normally-closed high-sensitivity vibration sensor 60, and the normally-closed high-sensitivity vibration sensor 60 is connected in parallel with the temperature control device 20. Because the cold-scalding protection device comprises the normally-closed high-sensitivity vibration sensor 60, the normally-closed high-sensitivity vibration sensor 60 is connected with the temperature control device in parallel, and cold-scalding prevention precision is improved. When the user is in a sleep state or in a long-time non-moving state, the main control device IC does not receive any trigger signal within 5 minutes because the normally-closed high-sensitivity vibration sensor 60 does not generate any trigger action, and the heating gear is automatically lowered by the temperature control device 20 until the lowest temperature gear (blue gear) is reached. When the normally closed high-sensitivity vibration sensor 60 generates a trigger action, the main control device IC receives the trigger signal and automatically returns to the heating gear set by the user through the temperature control device 20, so that the use function of the user is not affected. It should be noted that the 5 minutes described in this embodiment is only a preferable solution, and the specific time may be preset in the main control device IC according to the actual situation. The principle of the normally closed high-sensitivity vibration sensor 60 is as follows: when the angle switch is in an on state and is vibrated or moved, the roller which conducts current in the switch moves or vibrates, so that the passing current is disconnected or the resistance value of the resistor is increased to trigger the circuit. The switch is characterized in that the switch is normally in a conducting state and can be turned off briefly when vibrating, so that the sensitivity of the switch is high.
Preferably, the temperature control device 20 is connected in parallel with the normally closed high-sensitivity vibration sensor 60 and then connected with the carbon fiber heating patch 30 through the overheat protector 50. Because the temperature control device 20 and the normally-closed high-sensitivity vibration sensor 60 are connected in parallel and then connected with the carbon fiber heating patch 30 through the overheat protector 50, when the temperature is too high, the overheat protector 50 fuses, the carbon fiber heating patch 30 stops working, the high-temperature scalding caused by the too high temperature of the carbon fiber heating patch 30 is prevented, and the safety performance is improved.
Preferably, an indicator light 40 connected in parallel with the normally-closed high-sensitivity vibration sensor 60 is also arranged between the main control device IC and the carbon fiber heating patch 30. Because the indicator lamp connected with the normally-closed high-sensitivity vibration sensor 60 in parallel is further arranged between the main control device IC and the carbon fiber heating patch 30, the heating condition of the carbon fiber heating patch 3 is conveniently displayed. Notably, four heating stages may be provided in the main control IC: the highest heating level, the indicator light is red; a high-temperature heating block, and an indicator lamp is orange; the medium temperature heating gear, the pilot lamp shows the white; the low temperature heating shelves, pilot lamp shows the blue.
Preferably, the sensing surface of the normally closed high-sensitivity vibration sensor 60 is thickened and plated with gold. Because the sensing surface of the normally-closed high-sensitivity vibration sensor 60 is thickened and electroplated with gold, the dustproof, waterproof and oxidation-resistant capacities are improved, and the service life is prolonged.
Further, the purity of the electro-gold plating is 99.00% -99.99%. The purity of the electro-gold plating is 99.00% -99.99%, so that the dustproof, waterproof and oxidation-resistant capacities are further improved.
Furthermore, the purity of the electro-gold plating is 99.50% -99.99%, and the purity of the electro-gold plating is 99.50% -99.99%, so that the electro-gold plating has higher purity, and the dustproof, waterproof and oxidation-proof capabilities are further improved.
Still further, the purity of the electrogilding is 99.97 percent and higher, so that the dustproof, waterproof and oxidation-resistant capacities are further improved, and the service life is prolonged.
Preferably, the portable power source 10 is a lithium ion battery. Because the mobile power supply 10 is a lithium ion storage battery, the weight is reduced, and the mobile power supply is convenient to carry.
Preferably, the carbon fiber heating patch 30 is externally sleeved with a non-woven fabric layer. Because the non-woven fabric layer is sleeved outside the carbon fiber heating patch, the safety performance of the carbon fiber heating patch is improved.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
