Abstract
The invention discloses an automatic water changing system. The automatic water changing system comprises a power supply, an automatic water inlet valve, a water inlet pipe, a water level control switch, a water level sensor, a water outlet pipe, a metal dome switch and a shape memory alloy spring, wherein the power supply, the automatic water inlet valve, the metal dome switch and the water level control switch are connected in series, one end of the water inlet pipe is connected with a water outlet of the automatic water inlet valve, the pipe opening of one end of the water outlet pipe is sleeved with the shape memory alloy spring and is tightly closed so that hot water can not flow out, the shape memory alloy spring is connected with a metal dome of the metal dome switch, and the water level sensor is connected with the water level control switch. Compared with the prior art, the whole system is independent of other instruments and can be used for conducting automatic water changing while all the other instruments are not changed. The water changing temperature interval of the automatic water changing system depends on the deformation temperature of shape memory alloy, therefore, the shape memory alloy materials can be changed according to the requirements of different instruments on the temperatures, and the overall automatic water changing system can adapt to different instruments.
Description
Technical field
The invention belongs to water treatment field, particularly a kind of instrument water temperature that keeps is at the automatic water-exchanging system of certain limit.
Background technology
Current thermostatical instrument mostly is independent instrument, and major part needs to utilize the instrument of water for cooling substantially can only ensure that water temperature is unlikely to too high by artificial changing water, this not only added artificial burden and working time but also can not ensure temperature constantly definitely reach requirement.If use this thermostatical instrument in an experiment, this disposal route had both added the workload of experimenter, and manual operation likely introduces new error again, caused the out of true of testing.
So, in the urgent need to a kind of automatic water-exchanging system that can need automatic watering according to temperature, discharge water on market.
Summary of the invention
In order to overcome the deficiency mentioned in above-mentioned technical background, the present invention proposes a kind of automatic water-exchanging system that can need automatic watering according to temperature, discharge water.
The technical solution adopted in the present invention is: a kind of automatic water-exchanging system, comprising: power supply, automatic water inlet valve, water inlet pipe, level control switch for water, water level sensor and rising pipe; It is characterized in that, also comprise: elastic sheet switch and shape memory alloy spring, described power supply, automatic water inlet valve, elastic sheet switch and level control switch for water are connected in series, described water inlet pipe one end is connected with described automatic water inlet valve water delivering orifice, described shape memory alloy spring to be enclosed within described rising pipe one end mouth of pipe and to make it tightly prick and not allow hot water flow out, described shape memory alloy spring is connected with the shell fragment of described elastic sheet switch, and described water level sensor is connected with described level control switch for water.
As preferably, described power supply is chargeable lithium cell.
The present invention is relative to prior art, and whole system, independent of other instruments, can use this system to carry out automatic water-replacing while not changing other instrument entirety.The deformation temperature of marmem is depended in the coolant-temperature gage interval of changing of this automatic water-exchanging system, so according to the needs of different instrument to temperature, can change shape memory alloy material, then whole automatic water-exchanging system can be made to adapt to different instruments.
Accompanying drawing explanation
Fig. 1: be circuit theory diagrams of the present invention.
Fig. 2: be the system construction drawing of the embodiment of the present invention.
Embodiment
The technical program is further described below in conjunction with reference to accompanying drawing, the example of described embodiment is shown in the drawings, wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish, but this description is only for explaining the present invention, and can not be interpreted as limitation of the present invention.
Ask for an interview Fig. 1, the technical solution adopted in the present invention is: a kind of automatic water-exchanging system, comprising: chargeable lithium cell power supply 1, automatic water inlet valve 2, water inlet pipe 3, level control switch for water 4, water level sensor 5, elastic sheet switch 6, shape memory alloy spring 7 and rising pipe 8; Chargeable lithium cell power supply 1, automatic water inlet valve 2, elastic sheet switch 6 and level control switch for water 4 are connected in series, water inlet pipe 3 one end is connected with automatic water inlet valve 2 water delivering orifice, shape memory alloy spring 7 to be enclosed within the mouth of pipe of rising pipe 8 one end and to make it tightly prick and not allow hot water flow out, shape memory alloy spring 7 is connected with the shell fragment of elastic sheet switch 6, and water level sensor 5 is connected with level control switch for water 4.
Ask for an interview Fig. 2, the present invention is directly placed in the device that need change water, and wherein water level sensor 5 is positioned at the default peak level place that need change water device.
Operationally, when water level reaches water level sensor 5 place, and temperature is lower in the present invention, now elastic sheet switch 6 is in closure state, and level control switch for water 4 is in off-state, so whole circuit disconnects, water inlet pipe 3 place does not have cold water to flow out, and now water body heats;
When water temperature rises to the deformation temperature of shape memory alloy spring 7, shape memory alloy spring 7 shortens thicker, and rising pipe 8 is opened, and starts draining, makes the metal clips of elastic sheet switch 6 flick simultaneously; When after water level decreasing, water level sensor 5 does not sense water, then level control switch for water 4 closes, but is in off-state due to elastic sheet switch 6, so now whole circuit disconnects, water inlet pipe 3 place does not have cold water to flow out;
Along with hot water flows out, after below water level decreasing to rising pipe 8 mouth of pipe, water device internal temperature need be changed and drop to room temperature, shape memory alloy spring 7 is elongated again to attenuate, again tightened by the mouth of pipe of rising pipe 8, and pushed open by the metal clips of elastic sheet switch 6 and connect into circuit, level control switch for water 4 is still in closure state simultaneously, so whole circuit communication, water inlet pipe 3 place starts have cold water to flow out;
Along with cold water flows out, water level rises to water level sensor 5 place, and water level sensor 5 drives level control switch for water 4 to disconnect, then whole circuit is in off-state, and automatic water inlet valve 2 is closed automatically, and water inlet pipe 3 place flows into without cold water, and water body heats; Then complete one whole circulation.
These are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention, therefore, all any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
