Technical field
The utility model relates to a kind of solar water heater, is specifically related to a kind of water-temperature water-level pick-up unit of solar water heater.
Background technology
At present, lever-type its temp-sensing element of solar water heater water-temperature water-level detecting device is generally located in ball float, and because ball float floats on the surface, the temp-sensing element in ball float cannot detect the accurate temperature of water; In addition, the lever of this detecting device is all generally regular length, if the water tank of outside is replaced with larger-size, the ball float on lever just may be visited less than on the water surface so, and only way is to change whole detecting device, and this has obviously increased cost to user.
Summary of the invention
Deficiency in view of prior art existence, the utility model innovative design a kind of water temperature solar water heater water-temperature water-level detecting device that detects accurately, can mate with the water tank of different size, this detecting device includes housing, float, lever and electric signal transducer, described lever is provided with the fulcrum hinged with housing, described lever is provided with float the termination of long-armed section, described lever electrically connects at termination and the electric signal transducer of galianconism section, it is characterized in that: in long-armed section of described lever, be provided with temp-sensing element.
Between the termination of long-armed section of described lever and float, be also connected to expansion link, one end pivot bush unit of described expansion link is on long-armed section, and the other end of expansion link is fixedly connected with float.
Described electric signal transducer includes fixed contact and moving contact, and fixed contact is located on wiring board, and moving contact is located at the termination of lever short arm section.
Described float is a hollow ball, the bus that fixed contact is several intervals, and bus is provided with wire and is connected to wiring board, and moving contact is the shell fragment with elastic pressure, and shell fragment is pressed on fixed contact, and shell fragment is provided with wire and is connected to wiring board.
The joint portion of housing and lever is provided with sealing shroud, and the big opening end of sealing shroud is socketed on housing, and the osculum end of sealing shroud is placed on lever.
Described sealing shroud is a kind of turriform cover of rubber system.
Described temp-sensing element is electrically connected on the wiring board in housing, or is directly electrically connected to the circuit of outside.
According to a kind of solar water heater water-temperature water-level detecting device of the utility model design, due to temp-sensing element is arranged in the lever being in water all the time, the water temperature detecting is just very accurate, and telescopic lever is applicable to the water tank of different sizes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is scheme of installation of the present utility model.
Embodiment
As shown in Figure 1, this solar water heater water-temperature water-level detecting device, include housing 6, wiring board 7, float 1, lever 4 and electric signal transducer, lever 4 is provided with the fulcrum 11 hinged with housing 6, lever 4 is socketed with expansion link 2 one end of long-armed section, the outer end of this expansion link 2 is connected with float 1, like this by the telescopic level of adjustable telescopic rod 2 on long-armed section, just can make it to mate with the water tank 12 varying in size, in long-armed section of lever 4, be provided with in addition the temp-sensing element 3 electrically connecting with wiring board 7, this temp-sensing element 3 also can directly be connected with the circuit of outside, as long as water temperature can be detected, and transfer data to display panel or control circuit, because long-armed section of lever 4 is positioned at water tank 12 bottoms all the time, therefore, temp-sensing element 3 detects is exactly water temperature accurately.
Termination and the electric signal transducer of lever 4 galianconism sections electrically connect, this electric signal transducer includes fixed contact 8 and moving contact 10, fixed contact 8 is located on wiring board 7, moving contact 10 is located at the termination of lever 4 galianconism sections, and the bus that fixed contact 8 is several intervals, bus is provided with wire and is connected to wiring board 7, moving contact 10 is for having the shell fragment of elastic pressure, shell fragment is pressed on fixed contact 8, and shell fragment is provided with wire and is connected to wiring board 7, and wiring board 7 is connected with control circuit by electric wire 9.Wherein, bus also can directly be electrically connected to the control circuit of outside with shell fragment.
As shown in Figure 2, this solar water heater water-temperature water-level detecting device packs into from water tank 12 bottom surfaces, long-armed section of lever 4 swings with the lifting of expansion link 2 because of float 1, shell fragment on lever 4 its terminations of galianconism section is made arc operation thereupon, correspondingly contact with the bus one by one on wiring board 7, realize thus the detection of water level.For guaranteeing lever 4 when swinging up and down and housing 6 does not produce interference, the upper side of housing 6 must have certain activity space, if this space is not hidden, the flow of water must be from entering housing, affect electronic component, for this reason, at the upper side of housing 6, be provided with the turriform sealing shroud 5 of rubber system, the big opening end of sealing cover 5 covers on the upper side of housing 6, osculum end is wrapping tightly long-armed section of lever 4, because sealing tackling is flexible, not only guaranteed sealing, and for the swing of lever provides may.
According to a kind of solar water heater water-temperature water-level detecting device of the utility model design, owing to temp-sensing element being arranged in the lever being in water all the time, the water temperature detecting is just very accurate, and telescopic lever is applicable to the water tank of different sizes, compared with prior art, there is substantive distinguishing features and progress.
