Problems solved by technology

[0002] At present, the heating equipment in the market has replaced the traditional electric blanket to solve the harmful electromagnetic radiation. The water heating blanket is currently an updated product of the electric blanket, so as to be recognized by everyone. The water shortage device of the main unit of the water heating blanket on the market is made of The floating body is used to control the switch. If the floating body is soaked in water for a long time, it will be scaled and stuck, and it will not be resistant to high temperature, and has poor sensitivity. The sparks generated by the mechanical reed switch tube during power switching will also shorten the service life. The use of water heating blanket host accounts for about 80% of the current market. In order to solve this problem, the water shortage device in the water heating blanket host has been further improved.

Embodiment 1

[0014] Embodiment one, see figure 1 It is a water level control circuit of a plumbing blanket host, which consists of a water tank (1), a probe (K1), a probe (K2), a sealed shell (2), a photosensitive element (3), a neon lamp (4), and a resistor (R1) , resistor (R2), resistor (R3), resistor (R4), capacitor (C1), capacitor (C2), voltage regulator tube (D1), photosensitive component (U1), photosensitive component (U3), thyristor (T1 ), bridge stack (UR), control board (PCB), heating device (EH1), water pump (EH2), electrode probe (K1) and electrode probe (K2) are fixed on the host water tank (1), and the probe (K2) is connected to the circuit through a resistor (R1). The photosensitive component (U1) is composed of a sealed casing (2), a photosensitive element (3) and a neon lamp (4). The probe (K1) and the neon lamp (4) pass through the resistor (R2) into the circuit.

[0015] After the AC 220V voltage is stepped down by the resistor (R1) and the resistor (R2) (the resistance...

Embodiment 2

[0016] Embodiment two: see figure 2 The electrode probe (K1) is fixed on the host water tank, the metal body of the heating device (EH1) is used as another electrode probe to connect with the resistor (R1) and then connected to the circuit, and the host control board (PCB) is directly controlled by the photosensitive component (U1) For control, the electrode probe (K1), the photosensitive component (U3) and the entire rectification and voltage reduction circuit are omitted during the entire assembly process as required, and other working processes are the same as in the first embodiment.

Embodiment 3

[0017] Embodiment three: see image 3 The photosensitive component (U2) is composed of a sealed shell (2), a photosensitive component (3), a photosensitive component (5) and a neon lamp (4). Two photosensitive components are installed in the photosensitive component (U2) (the number of photosensitive components depends on the actual situation. set), the access method and lighting process of the neon lamp (4) are the same as in Embodiment 1, and the resistance of the photosensitive element (3) and the photosensitive element (5) is simultaneously reduced to Hundreds of ohms, thyristor (T2) and thyristor (T3) also work together, the control pin of thyristor (T2) is controlled by photosensitive element (3), and thyristor (T2) controls the heating tube ( EH1) works, the control pin of the thyristor (T3) is controlled by the photosensitive element (5), the thyristor (T3) controls the water pump to work, and the water shortage signal of the whole circuit is controlled by the photosen...

Abstract

The invention provides a water heating blanket host control circuit. According to the water heating blanket host control circuit, a photosensitive member and a neon lamp are integrally arranged by utilizing a principle that the neon lamp can be lightened just by an induced voltage, two electrode probes are installed on a host water tank, the neon lamp, the photosensitive member and a sealed shellform a photosensitive assembly, a certain resistance value is formed between two electrodes when the electrode probes detect a water level after the host water tank is filled with water, a 220 V voltage is directly reduced to a safety weak voltage by means of over 100 M resistors and then enters the host water tank, the weak induced voltage lightens the neon lamp connected in the circuit, and thephotosensitive member receives significant change of a resistance value of a light source, thus the photosensitive member drives the whole circuit to operate. The water heating blanket host control circuit does not cause noise nor mechanical wear, so that the service life of the entire host is doubled, and the whole operating process is low-carbon, energy-saving, environmentally friendly and mute.
