Technical Field
The utility model belongs to the technical field of the windscreen wiper water injection system of vehicle, concretely relates to windscreen wiper water spray hose system and vehicle with heating function.
Background
The automobile wiper system is used for removing water stains and dust left on the front windshield. Under the rainy environment, the visual field definition of a driver is ensured, and the driving safety in a rainy room is ensured. Particularly, in a non-rainy environment, when dust or impurities on the front windshield block the driving view, a wiper water spraying function is required, and cleaning liquid is sprayed for cleaning the glass. However, in an extremely cold environment, particularly in northeast regions, the temperature of minus 20 ℃ or even below can be reached in winter, and at the moment, some poor-quality glass cleaning liquid (even clear water used by users) can be frozen and solidified in a water spraying hose system, so that normal water outlet cannot be carried out. The glass cannot be cleaned timely and effectively, and the driving safety can be endangered in serious cases.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 3, in the present embodiment, a wiper water spray hose system with a heating function includes two wiper washing hoses 1 and a heating controller 3. The inner wall of the wiper washing hose 1 is provided with an electric heating wire 2. The heating controller 3 is respectively connected with each electric heating wire 2, and the heating controller 3 is used for controlling the on-off of the electric heating wires 2.
As shown in fig. 1, one end of one of the wiper washing hoses 1 is connected to a main driving spout, and the other end of the wiper washing hose 1 is connected to one of the water spray motors 5 provided at the vehicle-mounted watering can 4. Similarly, one end of another wiper washing hose 1 is connected to the secondary water spray port, and the other end of the wiper washing hose 1 is connected to another water spray motor 5 provided at the vehicle-mounted water spray can 4. And the water spraying motor 5 is connected to a power supply of the whole vehicle through a wire harness and is used for ensuring power supply energy required by a water spraying device and a heating function. The cleaning solution is stored in the vehicle-mounted water spray bottle 4, and is sprayed out from the vehicle-mounted water spray bottle 4 along the two wiper cleaning hoses 1 by the water spray motor 5.
As shown in fig. 2, an electric heating wire 2 is uniformly wound in the wiper washing hose 1, one end of the electric heating wire 2 is an anode 21, the other end is a cathode 22, and current flows from the anode 21 through the electric heating wire 2 and flows from the cathode 22 to the cathode bonding point 35 of the whole vehicle. The electric heating wire 2 can generate a certain amount of heat when current passes due to the thermosensitive effect, so that the effect of heating the inner wall of the wiper washing hose 1 is achieved, and the problem that the normal water spraying function is hindered due to the fact that liquid is solidified and frozen to block the wiper washing hose is solved.
As shown in fig. 3, in the present embodiment, the heating controller 3 includes a relay 32, a diode D1, a diode D2, a diode D3, a resistor R1, a resistor R2, a resistor R3, a transistor Q1, and a body switch 33; the specific connection relationship is as follows:
the first end of the vehicle body switch 33 is connected with the base electrode of the triode Q1 through the resistor R1, and the connection point of the resistor R1 and the base electrode of the triode Q1 is connected with the emitting electrode of the triode Q1 through the resistor R2. The first end of the vehicle body switch 33 is connected with an emitting electrode of the triode Q1 through the diode D2, the resistor R3 and the diode D3 in sequence, a connecting point between the emitting electrodes of the diode D3 and the triode Q1 is connected with a negative pole iron-bonding point 35 of the whole vehicle, and the negative pole iron-bonding point 35 of the whole vehicle is connected with a negative pole of the electric heating wire 2.

A first end of the switching part of the relay 32 is connected to the power pin 31, and a second end of the switching part of the relay 32 is connected to the positive electrode of the electric heating wire 2 through a pin 34.
When extreme cold weather occurs and liquid remained in the wiper washing hose 1 freezes to cause the hose to be blocked, a user can supply power to the electric heating wire 2 by operating the body switch 33, specifically:
when a user presses the vehicle body switch 33, the whole loop is conducted, current flows through the vehicle body switch 33 from the power supply pin 31 and returns to the cathode iron-bonding point 35 of the whole vehicle, at the moment, the switch part of the relay 32 is electrified and attracted by the coil part, the current can be output from the pin 34 through a circuit, the pin 34 is connected with the anode 21 of the electric heating wire 2, and the current returns to the cathode iron-bonding point 35 of the whole vehicle from the cathode 22 after passing through the electric heating wire 2. When the body switch 33 is pressed, the diode D3 will work, giving a working indicator light, from which the user can decide whether the wiper water spray hose system with heating function is successfully turned on.
