Abstract
The utility model provides a float built-in water level sensor used in solar energy water heater, consisting of a sensor casing, an inductive element and a floating ball with the inside containing magnetic material. The utility model is characterized in that: the floating ball is freely arranged inside the cavity of the sensor casing. Due to being no longer covered outside the sensor casing but being freely arranged inside the cavity of the sensor casing, the floating ball can float on the liquid surface inside the casing to move freely; moreover, as long as the gap between the floating ball and the sensor casing is big enough, the floating ball can not get stuck even when both the floating ball and the sensor casing are covered by scale, thereby guaranteeing reliability of the water level sensor.
Description
Technical field:
The utility model belongs to the level sensor technical field, refers more particularly to the float-ball type level sensor that solar water heater is used.
Background technology:
Level sensor is of a great variety, chattering type, float-ball type, pressure type or the like, and what solar water heater mainly used in the market is ball float external level sensor, because the incrustation scale influence, life of product is very short.As the patent No. is that the disclosed straight tube level sensor of the Chinese patent technology of ZL99227424 also is difficult to the influence of thoroughly avoiding incrustation scale to bring, its main cause is between its sensor housing and the ball float inwall very big gap to be arranged, if after tying incrustation scale, can cause ball float " stuck " and lost efficacy.
Summary of the invention:
The purpose of this utility model is to provide a kind of built-in level sensor of ball float of dependable performance.
The utility model is achieved through the following technical solutions: the built-in level sensor of ball float, form by sensor housing, sensing element, the ball float that includes magnetic material, it is characterized in that the ball float that includes magnetic material freely is placed in the sensor housing cavity.
Because ball float of the present utility model no longer is enclosed within the sensor shell external body, but freely be placed in the sensor housing cavity, floatability free movement on the enclosure interior liquid level, as long as the gap between ball float and the sensor housing is enough big, even ball float and sensor all scaling can not make ball float " stuck " yet, thereby guaranteed the reliability of level sensor.
Description of drawings:
Fig. 1 is a kind of embodiment structural representation of the present utility model.
Fig. 2 is the another kind of embodiment structural representation of the utility model.
Embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
In conjunction with Fig. 1, Fig. 2 as can be seen, the built-in level sensor of ball float is made up of sensor housing 2, sensing element 3, the ball float 1 that includes magnetic material, it is characterized in that the ball float 1 that includes magnetic material freely is placed in the cavity of sensor housing 2.As shown in Figure 1, sensor housing 2 can be a tubular shell, and has limbers 4 at two positions up and down of housing at least; As shown in Figure 2, sensor housing 2 also can be the frame-type housing that is made of at least three cylinders; Sensing element 3 can be dry-reed tube switch or Hall switch or other magnetosensitive sensing element, and sensing element 3 be arranged between the inside and outside wall of housing 2 or coat waterproof material after be arranged at the outside of housing.
Principle of work of the present utility model is: when the water tank middle water level rose, the water level in the sensor housing 2 rose synchronously, and ball float 1 also rises thereupon, triggered sensing element 3 when arriving certain position, just can measure the height of water level.During decline of water table, principle is identical.
