Description

Technical Field

[0001] This utility model relates to the field of medical and health care equipment technology, and in particular to a mountain photovoltaic electric fire bucket that utilizes photovoltaic power generation technology to provide convenient, safe and energy-saving treatment for chronic leg pain in mountain residents. Background Technology

[0002] In many sparsely populated mountainous areas of my country, where power supply is unstable or difficult to access, the people mainly rely on agriculture and have relatively underdeveloped economies. Due to the unpredictable climate of the mountains, coupled with high air humidity and the large temperature difference in the rice paddies during the 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 ailments. The poor living environment, inconvenient transportation, and distance from cities in the mountains make the treatment of "old cold legs" very difficult.

[0003] The simple electric fire buckets used in the current technology treat chronic leg pain by immersing the legs in them and heating them. When the electric fire bucket gets too hot, the power must be turned off manually, which is very troublesome to operate. Long-term use of this type of electric fire bucket is affected by air humidity, which poses certain safety hazards. Moreover, the lifespan is relatively short. In addition, the local power supply in mountainous areas is unstable, making it difficult to achieve the expected therapeutic effect. The electricity cost is also a considerable expense. At the same time, people in areas without power supply can only suffer from the pain of chronic leg pain.

[0004] If there were an electric fire bucket that could be used safely in mountainous areas, even in areas without electricity, and that could reduce electricity costs while also achieving the goal of treating and rehabilitating chronic leg pain, that would be what patients with chronic leg pain are hoping for.

[0023] Advantages of this photovoltaic electric fire bucket suitable for remote mountainous areas:

[0024] (1) This photovoltaic electric fire bucket, which is suitable for remote mountainous areas, uses photovoltaic panels to charge the energy storage battery, thus solving the problem of providing all-weather treatment for old leg pain in areas with unstable or no power.

[0025] (2) This photovoltaic electric fire bucket, which is applicable to remote mountainous areas, uses photovoltaic power generation to save electricity expenses for people in mountainous areas.

[0026] (3) This photovoltaic electric fire bucket, which is suitable for remote mountainous areas, uses ITO conductive film glass for heating. The infrared wavelength produced is almost the same as the wavelength required by the human body, and the therapeutic effect is better than that of electric heating wire heating.

[0027] (4) The photovoltaic electric fire barrel temperature control instrument applicable to remote mountainous areas adopts a pointer-type temperature control digital display meter instead of a fully digital display temperature control meter. This is mainly because it is difficult for people in mountainous areas to set the temperature. With a pointer-type temperature control digital display meter, the temperature setting can be done simply by rotating the knob, which is more convenient to operate.

[0028] (5) This photovoltaic electric fire barrel temperature control instrument, applicable to remote mountainous areas, achieves the required automatic temperature control.

[0029] (6) This photovoltaic electric fire bucket, which is suitable for remote mountainous areas, uses a photoelectric beam switch to detect whether someone needs treatment, so as to realize automatic control: heating can only be started when a person's leg is put in, and heating will automatically stop when the person's leg is removed, so as to avoid the waste of energy storage battery due to misoperation.

[0030] (7) This photovoltaic electric fire bucket photovoltaic charge and discharge controller, which is applicable to remote mountainous areas, has overcharge and over-discharge functions, which can effectively protect the service life of energy storage batteries.

[0031] (8) The photovoltaic electric fire bucket applicable to remote mountainous areas is equipped with a voltmeter to facilitate observation of the battery voltage status of the energy storage battery box, whether there is a low-power state or a fully charged state, and an ammeter to facilitate observation of the working current status of the ITO heating glass, thereby determining whether there is any damage.

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

[0060] The photovoltaic panels are installed outdoors in a sunny location and tilted at an optimal angle according to the local latitude and longitude. The photovoltaic panels are then electrically connected to the three-pin power socket on the control box, so that the energy storage battery box 202 inside the control box can be charged during the day. Due to the setting of the photovoltaic charge and discharge controller 206, the charging and discharging can be managed, such as undervoltage protection, overcharge and over-discharge functions.

[0061] When button self-locking switch 213 is pressed, voltmeter 204, pointer-type temperature control digital display 205, infrared transmitter switch 117, and infrared receiver switch 118 are powered on. At this time, voltmeter 204 displays the current energy storage voltage. If no leg is inserted into the plug plate 102U port of the electric fire bucket, the infrared light from infrared transmitter switch 117 is received by infrared receiver switch 118. The signal output voltage of infrared receiver switch 118 is low voltage. Because the signal output voltage of infrared receiver switch 118 is... When the pointer-type temperature control digital display 205's control contact (in the conducting state) reaches the control terminals of the four DC solid-state relays 207, the load terminal contacts of the four DC solid-state relays 207 are in the non-conducting state, the four ITO heating glass are in the unheated state, the voltage drop across the shunt 209 is zero, the two ends of the shunt 209 are electrically connected to the ammeter 203, and the ammeter 203 is in the zero-ampere indication state; when a leg is inserted into the plug plate 102U port of the electric fire bucket, the infrared emitting switch 117 does not transmit infrared light. When the external receiving switch 118 receives the signal, the output voltage signal of the infrared receiving switch 118 is high. At this time, the high voltage signal reaches the control terminals of the four DC solid-state relays 207 through the control contacts of the pointer-type temperature control digital display 205. At this time, the load terminal contacts of the four DC solid-state relays 207 are in a conducting state, and the four ITO heating glass are in a heating state. The voltage drop across the shunt 209 is not zero, and the ammeter 203 is in a non-zero ampere indication state. When the electric fire box reaches the set temperature, the control contacts of the pointer-type temperature control digital display 205 are in a disconnected state. At this time, the control terminals of the four DC solid-state relays 207 lose voltage and disconnect the load terminal contacts of the four DC solid-state relays 207, thus the four ITO heating glass are de-energized and stop heating. It is easy to understand that when the temperature of the electric fire box is lower than the set temperature, the entire system realizes the automatic temperature control function. When a person's leg leaves the electric fire box, the entire system will stop heating and enter a standby state.

[0062] The above description is only one embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
