Description

Technical Field

[0001] This utility model belongs to the field of automatic control technology, and in particular relates to a circuit control device based on solvent. Background Technology

[0002] Currently, the commonly used technologies in the industry are as follows:

[0003] A relay is an electrical control device that interacts with both the control system (also known as the output circuit) and the multi-control system (also known as the output circuit). It is commonly used in automated control circuits, essentially acting as an "automatic switch" that uses a small current to control a large current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching.

[0004] Relay control technology is one of the most fundamental and commonly used technologies in the field of automation control. It primarily uses an electromagnetic mechanism to drive switch contacts, changing the on / off state of a circuit to achieve remote control of the controlled load. Relays are widely used in industrial control, household appliances, and automatic detection equipment due to their advantages such as electrical isolation and strong driving capability. In existing technologies, switching control is generally achieved through the cooperation of mechanical contacts and electromagnetic coils. Their on / off state mainly depends on the input of external electrical signals, and no direct feedback control mechanism is formed for changes in environmental factors such as humidity or the presence of liquid media.

[0005] While publicly available technologies such as US5699218A, which utilize magnet-driven relays, have improved contact life and response speed, their control logic remains based on electrical signal triggering and fails to address the technical requirement of automatically switching control paths when the medium's state changes (e.g., the presence or absence of water). When applied to circuits involving liquid detection, immersion control, or control based on physical states, these existing technologies cannot automatically adjust relay on / off states according to the liquid medium's own condition, necessitating additional sensors or external controllers, leading to increased system complexity and cost.

[0006] Therefore, how to construct a relay control device that can automatically switch control paths according to the conductivity state of the liquid medium and control the operation of different loads in both anhydrous drying and water-immersed environments is a technical problem that has not yet been solved by existing technology. Utility Model Content

[0007] In view of the problems existing in the prior art, this utility model provides a solvent-based circuit control device.

[0008] This invention is implemented as follows: a solvent-based circuit control device is provided with:

[0009] Electromagnet;

[0010] The lower end of the electromagnet is fixed to the base with screws. A supporting vertical rod is welded to the upper end of the base. A horizontal rod is connected to the upper end of the supporting vertical rod via a shaft. A tension spring is connected between the left end of the horizontal rod and the left end of the base. A metal plate is embedded in the middle of the horizontal rod. The metal plate is located at the upper end of the electromagnet. An upper contact plate is provided on the upper side of the right end of the horizontal rod. A lower contact plate is provided on the lower side of the right end of the horizontal rod. Conductive contacts are welded to the upper and lower sides of the right end of the horizontal rod.

[0011] The electromagnet has two poles electrically connected to a first power source and a relay. The relay has a conductive groove inside, in which dissolved compound particles are placed. A drying circuit is provided on the side of the relay. One end of the drying circuit is electrically connected to the lower contact plate, and the other end of the drying circuit is connected to the second power source and the second load in sequence. The other end of the second load is electrically connected to the conductive contact on the outside of the crossbar.

[0012] The upper contact plate is electrically connected to the first load and the third power supply in sequence, and the other end of the third power supply is electrically connected to the conductive contact on the outside of the crossbar.

[0013] Furthermore, a heating wire is electrically connected in the middle of the drying circuit.

[0014] Furthermore, conductive contacts corresponding to the crossbar are welded to the lower end of the upper contact plate and the upper end of the lower contact plate.

[0015] In summary, the advantages and positive effects of this utility model are as follows:

[0016] The relay circuit of this invention is separated by a conductive groove. The conductive groove contains a soluble substance used to control the relay's operation. This solute is non-conductive when dry, but the solution becomes highly conductive after dissolving in a solvent. When the solute dries, the relay circuit is open; when the solute is introduced into the solvent, the relay circuit is closed. A heating wire is added to the relay control circuit to control whether the solute dries. To close the relay circuit, the solvent is introduced into the solute; to open the relay circuit, the solvent is drained, and the solute is dried by the heating wire.

[0017] By switching the solvent on and off, automatic control of the relay is achieved, thereby realizing automatic control of the controlled circuit. This invention can be widely used in the design of solvent-based circuit control systems, such as automatic opening and closing control of car doors and windows, and various automatic drainage control systems.

Detailed Implementation

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the circuit control device of this utility model consists of an electromagnet 1, a base 2, a supporting vertical rod 3, a horizontal rod 4, a tension spring 5, a metal plate 15, and contact components, forming a mechanical linkage system. The electromagnet 1 is fixed above the base 2, and the supporting vertical rod 3 is vertically welded to the base 2. Its upper end is rotatably connected to the horizontal rod 4 through a rotating shaft, allowing the horizontal rod 4 to swing around the upper end of the supporting vertical rod 3. The left end of the horizontal rod 4 is connected to the left side of the base 2 through the tension spring 5, so that the horizontal rod 4 is pulled by the tension spring 5 to maintain its return position when not under force. The metal plate 15 is embedded in the middle of the horizontal rod 4 and faces the upper end of the electromagnet 1. When the electromagnet 1 is energized, it generates an attractive force on the metal plate 15, causing the horizontal rod 4 to rotate around the supporting vertical rod 3. This causes the upper contact plate 6, the lower contact plate 7, and the conductive contact 8 on the right end of the horizontal rod 4 to change position, realizing the conversion from mechanical action to electrical switching.

[0022] An upper contact plate 6 is fixedly installed on the upper side of the right end of the crossbar 4, and a lower contact plate 7 is fixedly installed on the lower side. Conductive contacts 8 are welded to the upper and lower sides of the right end of the crossbar 4 at positions corresponding to the lower ends of the upper contact plate 6 and the upper ends of the lower contact plate 7. As the crossbar 4 swings under the attraction or release of the electromagnet 1, the conductive contacts 8 can selectively contact the upper contact plate 6 or the lower contact plate 7, thus forming different conduction paths. When the electromagnet 1 is attracted, the metal sheet 15 is attracted, and the crossbar 4 rotates in the direction of the electromagnet 1, causing the conductive contacts 8 to come into contact with the upper contact plate 6, forming the first conduction state; when the electromagnet 1 is de-energized, the crossbar 4 returns to its original position under the traction of the tension spring 5, causing the conductive contacts 8 to detach from the upper contact plate 6 and move closer to the lower contact plate 7, forming the second conduction state. This realizes the switching of two different circuit states driven by a single mechanical action.

[0023] Electromagnet 1 is electrically connected to a first power source 16 and a relay 9. The relay 9 has a conductive groove 10 filled with dissolved, conductive compound particles. A drying circuit 11 is located on the side of the relay 9, with a heating wire 12 connected in series within it. One end of the drying circuit 11 is connected to a lower contact plate 7, and the other end of the heating wire 12 is sequentially connected to a second power source 17 and a second load 14, ultimately connecting back to the conductive contact 8 on the outside of the crossbar 4. When the conductive contact 8 contacts the lower contact plate 7, the drying circuit 11 is energized, and the heating wire 12 heats and dries the interior of the relay 9, causing the solvent in the conductive groove 10 to evaporate and the compound particles to lose their conductivity, thus disconnecting the relay 9. When the conductive contact 8 contacts the upper contact plate 6, the drying circuit 11 is de-energized, the conductive groove 10 returns to its solvent environment, the compound particles regain their conductivity, and the relay 9 closes, achieving coordinated control between the solvent state, electromagnetic action, and circuit conduction state.

[0024] The upper contact plate 6 is sequentially connected to the first load 13 and the third power supply 18, and forms a circuit with the crossbar 4 through the conductive contact 8 to realize the on / off control of the first load 13; the lower contact plate 7 controls the heating wire 12 and the second load 14 through the drying circuit 11 to realize the on / off control of the second load 14. The first power supply 16 is responsible for the basic control functions of driving the electromagnet 1 and the relay 9, the second power supply 17 provides energy to the drying system, and the third power supply 18 supplies power to the first load 13. The three power supplies respectively undertake the driving, regulating and output functions. Under the linkage of the core mechanical action of the crossbar 4 position change, the relay state, solvent conductivity state and load on / off state are synchronously switched, thus forming a multi-state collaborative control circuit system based on solvent conductivity characteristics and electromagnetic mechanical linkage.

[0025] The circuit of this utility model mainly includes three parts: (1) relay circuit; (2) controlled circuit CDFE; (3) controlled circuit EHG.

[0026] 1. Substance X is placed between relay circuits A and B to control the relay operation. Substance X has the following characteristics: (1) It does not conduct electricity when dry; (2) The solution has good conductivity after dissolving in a solvent. For example, substance X can be table salt (NaCl), etc., and the solvent can be water, etc. 2. A heating wire is placed between controlled circuits C and D to dry substance X. 3. When substance X is drying, the relay circuit is disconnected, electromagnet 1 is de-energized, and tension spring 5 pulls the crossbar 4, so that the conductive contact of the crossbar 4 contacts and connects with the upper contact plate 6, the controlled circuit EHG forms a loop, and the first load 13 of the device between G and H works.

[0027] 4. When water flows into the conductive tank 10, it dissolves substance X. The relay circuit closes, the electromagnet 1 is energized, attracting the metal plate 15, causing the crossbar 4 to press down and contact the lower contact plate 7. The controlled circuit CDFE forms a loop, and the second load 14 of the device between E and F operates, while the heating wire between C and D operates. When the water supply is stopped, substance X in the conductive tank 10 is dried by the drying circuit 11. The relay circuit opens, the controlled circuit EHG forms a loop, and the device between G and H operates.

[0028] The circuit system of this invention consists of three parts working together: a relay circuit, a controlled circuit CDFE, and a controlled circuit EHG. The relay circuit senses the state of substance X within the conductive tank and drives the electromagnet 1. The controlled circuits CDFE and EHG control the operating states of the second load 14 and the first load 13, respectively. Substance X is non-conductive in its dry state and exhibits good conductivity in its solution after dissolving in a solvent. When substance X is in different physical states, the on / off state of the relay circuit drives the horizontal bar 4 to switch positions, thereby achieving automatic switching between different controlled circuits.

[0029] In the initial or anhydrous state, the substance X in the conductive tank 10 is dry and does not have conductivity. The relay circuit is in the open state, the electromagnet 1 is de-energized, the metal sheet 15 is not attracted, and under the traction of the tension spring 5, the horizontal bar 4 returns to its original position around the supporting vertical bar 3, so that the conductive contact contacts make contact with the upper contact plate 6, thereby forming a closed loop in the controlled circuit EHG. The first load 13 receives power from the third power source and starts to work, while the controlled circuit CDFE is in the open state, and the second load 14 and the heating wire do not work.

[0030] When water flows into the conductive tank 10, substance X dissolves in the water to form a conductive solution. The relay circuit changes from an open state to a closed state. After the electromagnet 1 is energized, it generates a magnetic force to attract the metal piece 15, causing the horizontal bar 4 to rotate downward around the supporting vertical bar 3. The conductive contact separates from the upper contact plate 6 and contacts the lower contact plate 7, thereby cutting off the controlled circuit EHG and closing the controlled circuit CDFE, so that the second load 14 starts to work. At the same time, the heating wire is energized and heats up to dry the substance X in the conductive tank 10.

[0031] When the water flow stops, the heating wire continues to operate, causing the solvent in the conductive tank 10 to gradually evaporate. Substance X returns to a dry state and loses its conductivity. The relay circuit disconnects again, the electromagnet 1 is de-energized, and the crossbar 4 resets under the action of the tension spring 5, causing the conductive contacts to re-engage with the upper contact plate 6. The controlled circuit EHG closes again, the first load 13 is put into operation again, and the controlled circuit CDFE disconnects. This forms an automatic switching control mechanism based on the conductivity characteristics of dissolved substances and the synergistic effect of electromagnetic drive and mechanical commutation, realizing intelligent switching and self-recovery control of different loads under water-containing and waterless conditions.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
