Buoyancy resistance induction type water heater water level sensor

Abstract

The invention discloses a buoyancy resistance induction type water heater water level sensor. The buoyancy resistance induction type water heater water level sensor comprises a connection assembly, a framework rod, a floating rod, a floating ball and an arc-shaped slide rheostat; the outer peripheral surface of the tail part of the connection assembly is provided with a connection thread; the head part of the connection assembly is provided with a concave cavity; the framework rod is axially and slidably arranged in the connection assembly in a penetrating manner; the head of the framework rod is fixedly connected with the head end of the floating rod;the floating ball is fixedly connected with the head end of the floating rod;one end of the arc-shaped sliding rheostat is fixedly connected with the framework rod; a sliding piece of the arc-shaped sliding rheostat is fixedly connected with the floating rod; the arc-shaped sliding rheostat is located in the concave cavity; a sealing sleeve for sealing the concave cavity is connected between the floating rod and the head end face of the connection assembly. The influence of scale on the sensor can be avoided, the requirement for the installation space is small, and the sensor is suitable for water level measurement in the narrow space.

Description

technical field [0001] The invention relates to a water level sensor, in particular to a buoyancy resistance inductive water heater water level sensor. Background technique [0002] The temperature of a solar or electric water heater equipped with running water changes sharply during the heating process, and the water temperature varies in a large range, and it needs to maintain a high temperature for a long time after heating. Moreover, the water quality entering the water heater is generally hard and prone to scale. These characteristics of the water in the water heater cause alternating thermal shock and fouling to the water level sensor, which can easily cause damage to the photoelectric and ultrasonic type water level sensors. The use of a float-type water level sensor can reduce the impact of scale on the sensor, but the float-type water level sensor relies on the float to float up and down for water level monitoring, and has a large range of up and down activities.

Moreover, the water quality entering the water heater is generally hard and prone to scale

These characteristics of the water in the water heater cause alternating thermal shock and fouling to the water level sensor, which can easily lead to damage to the photoelectric and ultrasonic water level sensors

The use of a float-type water level sensor can reduce the impact of scale on the sensor, but the float-type water level sensor relies on the float to float up and down for water level monitoring, and has a large range of up and down activities. It is usually threaded during installation, and the water level sensor needs to be rotated Therefore, when the space on both sides of the water tank is small, the floating ball water level sensor is easy to collide with the side wall of the water tank when installed, and may also collide with other parts in the water tank, causing damage to the floating ball
