Abstract
The utility model discloses a water temperature and water-level sensor, which comprises a water temperature and water-level sensing circuit, stainless steel induction pipes, a silica gel segment and a stainless steel sleeve, wherein the stainless steel induction pipes are sleeved outside the water temperature and water level sensing circuit at an interval and are respectively communicated with circuits, the silica gel segment is arranged between two adjacent stainless steel induction pipes, silica gel is filled in the stainless steel induction pipes, the silica gel and the silica gel segment are integrated by primary mould pressing, an insulating support body which is integrated with the outer wall of the silica gel segment is arranged on the outer wall of the silica gel segment, the stainless steel sleeve is cased outside the stainless steel induction pipe and the silica gel segment support body, the stainless steel induction pipes at the top end and the outermost lateral end are conducted and connected, and a water inlet is arranged on the lateral wall of the stainless steel sleeve. Since the stainless steel induction pipes, the silica gel segment and the stainless steel sleeve can be totally separated by the insulating support body arranged on the outer wall of the silica gel segment, the work stability of the sensor is guaranteed, and the service span of the sensor is prolonged.
Description
Technical field
The utility model relates to a kind of water-temperature water-level sensor, especially a kind of sensor that is used to detect the water-temperature water-level in the solar water heater water tank.
Background technology
Water-temperature water-level sensor is arranged in the water tank of solar water heater, be used to detect water temperature and water level in the water tank, its structure generally comprises water-temperature water-level sensing circuit, stainless steel sensor pipe, heat-shrink tube and stainless steel sleeve pipe, stainless steel sensor pipe spacer sleeve also is connected with circuit respectively in water-temperature water-level sensing circuit outside, heat-shrink tube is connected between adjacent two stainless steel sensor pipes, the stainless steel sleeve pipe is located at the outside of stainless steel sensor pipe and heat-shrink tube, and its top links to each other with the stainless steel sensor pipe of outermost side.Because its sensing circuit of sensor of this class formation work easily is malfunctioning, the serviceable life of sensor is shorter, therefore the applicant has proposed the improvement structure, change heat-shrink tube into the silica gel section, be full of silica gel in stainless steel sensor pipe inside, silica gel and silica gel section form one, to guarantee the stability of working sensor, increase the service life.But find in the use, because of silica gel softer, during use stainless-steel tube easily be enclosed within its outside stainless steel sleeve pipe and come in contact, thereby make its cisco unity malfunction.
Summary of the invention
Technical problem to be solved in the utility model is to propose the water-temperature water-level sensor of a kind of good operating stability, long service life.
For solving the problems of the technologies described above, a kind of water-temperature water-level sensor of the utility model comprises the water-temperature water-level sensing circuit, the stainless steel sensor pipe, silica gel section and stainless steel sleeve pipe, described stainless steel sensor pipe spacer sleeve also is connected with circuit respectively in water-temperature water-level sensing circuit outside, described silica gel section is located between described adjacent two stainless steel sensor pipes, described stainless steel sensor pipe inside is full of silica gel, described silica gel and described silica gel section form one by one-step mould, the outer wall of described silica gel section is provided with the insulation support body that forms one with it, described stainless steel sleeve pipe box is located at the outside of described stainless steel sensor pipe and silica gel section supporter, its top links to each other with the stainless steel sensor pipe conducting of outermost side, and the sidewall of described stainless steel sleeve pipe is provided with the inlet opening.
Above-mentioned a kind of water-temperature water-level sensor, described insulation support body are four projectioies along the circumference equal distribution.
The utility model is owing to adopted technique scheme, insulation support body set on the silica gel section outer wall can will definitely separate between stainless steel sensor pipe and silica gel section and the stainless steel sleeve pipe, do not contact thereby can not take place to make between stainless steel sensor pipe and the stainless steel sleeve pipe because of the silica gel section is soft partially, and then cause the inoperable phenomenon of sensor, guarantee the stability of working sensor, prolonged the serviceable life of sensor.Employing, can make it form cross supporting frame, thereby can further strengthen the reliability of its support as insulation support body along four projectioies of circumference equal distribution.
Description of drawings
Fig. 1 is the local hollow structure synoptic diagram of the utility model water-temperature water-level sensor;
Fig. 2 is that A-A among Fig. 1 is to dissecing structural representation.
Embodiment
As shown in Figure 1, water-temperature water-level sensor comprises water-temperature water-level sensing circuit 7, stainless steel sensor pipe 1, silica gel section 2 and stainless steel sleeve pipe 3, stainless steel sensor pipe 1 spacer sleeve also is connected with circuit 7 respectively in water-temperature water-level sensing circuit 7 outsides, and silica gel section 2 is located between adjacent two stainless steel sensor pipes 1.The inside of stainless steel sensor pipe 1 is full of silica gel, silica gel and silica gel section 2 form one (during making by one-step mould, the water-temperature water-level sensing circuit 7 and the stainless steel sensor pipe 1 that have linked together are placed mould, inject the silica gel fluid, adopt a compression moulding to form as one).The outer wall of silica gel section 2 is provided with suppresses all-in-one-piece silica gel supporter 6 with it, and stainless steel sleeve pipe 3 is sheathed on the outside of stainless steel sensor pipe 1 and silica gel supporter 6, and its top links to each other by stainless steel screw 4 conductings with the stainless steel sensor pipe 1 of outermost side.The sidewall of stainless steel sleeve pipe 3 is provided with inlet opening 5.
As shown in Figure 2, the silica gel supporter 6 on silica gel section 2 outer walls is four projectioies along the circumference equal distribution, forms a cross supporting frame.
In the utility model structure, silica gel supporter 6 is not limited to be pressed into one with silica gel section 2, also can adopt other insulating material to be fixedly linked with it and form.The structure of silica gel supporter 6 also is not limited to cross supporting frame, can adopt different structures such as establishing the limbers in triangular support bracket, the circle wall projection.
