Description

Technical Field

[0001] The present invention relates to the technical field of medical care equipment, and in particular to a photovoltaic electric fire bucket in mountainous areas, which utilizes photovoltaic power generation technology to provide convenient, safe and energy-saving treatment equipment for cold legs for residents in mountainous areas. Background Art

[0002] There are many mountainous areas in our country with sparse population, unstable power supply or difficulty in power supply. The people in these areas mainly engage in farming and have a relatively backward economy. Due to the unpredictable climate in the mountains and the high humidity in the air, and the large temperature difference in water temperature when working in the mountain rice fields in summer, the health of the people is adversely affected. Many people in these areas suffer from knee osteoarthritis (commonly known as old cold legs), rheumatism and other diseases. Due to the poor living environment in the mountainous areas, inconvenient transportation and distance from the city, it is very difficult for the people to treat old cold legs.

[0003] The simple electric fire bucket used in the prior art treats cold legs by heating the legs by placing them in it. When the electric fire bucket is overheated, the power is manually turned off, which is very troublesome to operate. The long-term use of this electric fire bucket is affected by air humidity, and there are certain hidden dangers in its safety. In addition, the lifespan is relatively short. In addition, the local power supply in mountainous areas is unstable, making it difficult to achieve the expected treatment effect. The electricity bill is also a considerable expense. At the same time, people in areas without power supply can only suffer from the pain of cold legs.

[0004] If there is an electric fire bucket that can be used in mountainous areas, which is safe to use and can be used even in mountainous areas without electricity, and can reduce electricity bills, and at the same time achieve the purpose of treating and rehabilitating old cold legs, this is what patients with old cold legs are looking forward to.

[0059] The working principle of this photovoltaic electric fire bucket suitable for remote mountainous areas:

[0060] The photovoltaic panel is installed outdoors in a sunny place and tilted at an optimal angle according to the local longitude and latitude. The photovoltaic panel is electrically connected to the three-pin power socket on the control box. In this way, the energy storage battery box 202 in the control box can be charged during the day. Due to the setting of the photovoltaic charge and discharge controller 206, the charge and discharge can be managed, for example, undervoltage protection, overcharge and over-discharge functions, etc.

[0061] Press the button self-locking switch 213, the voltmeter 204, the pointer-type temperature control digital display 205, the infrared transmitting switch 117, the infrared receiving switch 118, and the voltmeter 204 are powered on and work. At this time, the voltmeter 204 displays the current energy storage voltage. If the electric fire bucket has no legs placed in the plug plate 102U port, the infrared ray of the infrared transmitting switch 117 is received by the infrared receiving switch 118, and the signal output voltage signal of the infrared receiving switch 118 is low voltage. Since the signal output voltage signal of the infrared receiving switch 118 passes The control contact of the pointer-type temperature control digital display 205 (in the conductive state) reaches the control end of the four DC solid-state relays 207. At this time, the load end contacts of the four DC solid-state relays 207 are in a non-conductive state, and the four ITO heating glasses are in an unheated state. At this time, the voltage drop across the shunt 209 is zero, and the two ends of the shunt 209 are electrically connected to the ammeter 203, and the ammeter 203 is in a zero-ampere indication; when someone's leg is placed in the plug plate 102U port of the electric fire bucket, the infrared ray of the infrared emission switch 117 is not red. The external receiving switch 118 receives the signal, and the output voltage signal of the infrared receiving switch 118 is a high voltage. At this time, the high voltage signal reaches the control end of the four DC solid-state relays 207 through the pointer-type temperature control digital display 205 control contact. At this time, the load end contacts of the four DC solid-state relays 207 are in the on state. At this time, the load end contacts of the four DC solid-state relays 207 are in the on state, the four ITO heating glasses are in the heating state, and the voltage drop across the shunt 209 is not zero. At this time, the ammeter 203 is in a non-zero ampere indication state. When the inside of the electric fire box reaches the set temperature, the pointer-type temperature control digital display 205 control contact is in the disconnected state. At this time, the control end of the four DC solid-state relays 207 loses voltage and disconnects the load end contacts of the four DC solid-state relays 207, so that the four ITO heating glasses are powered off and stop heating. It is not difficult to understand that when the temperature of the electric fire bucket is lower than the set temperature, the entire system realizes the automatic temperature control function. When the human leg leaves the electric fire bucket, the entire system will stop heating and be in standby state.

[0062] The above is only one embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the principles of the present invention, and these should also be regarded as falling within the scope of protection of the present invention.
