FIG. 1A is a perspective view showing a disassembled embodiment of the separation type liquid level control device of the present invention, and FIG. 1B is a view showing an assembly of an embodiment of the separation type liquid level control device of the present invention. Rear perspective view.

The split type liquid level control device 100 includes a float chamber 101, a control unit 102, and a reed switch unit 103. The float chamber 101 has an accommodation space S, an upper cover 101a, and a lower cover 101b. In this embodiment, it is realized by a square casing, but the invention should not be limited thereto, and can be satisfied by any shape of the casing according to user requirements.

The upper cover 101a can be disposed at the top end of the accommodating space S, and the upper cover has at least one vent hole O for the air to flow into or out of the float chamber 101; the lower cover 101b is disposed at the bottom surface G of the float chamber 101, wherein the control unit 102 It is placed in the accommodating space S. In other words, the control unit 102 can move with the liquid level of a liquid lower than that in the accommodating space S.

In the present embodiment, the float chamber 101 and the control unit 102 of the split type liquid level control device 100 are disposed in water, and the control unit 102 has a magnet 102a therein, wherein the magnet 102a can be realized by a permanent magnet, and the present invention This should not be limited to this. Furthermore, the control unit 102 has a smaller specific gravity than water, so that the control unit 102 can move up or down in the accommodating space S according to the change of the water surface height or low. Therefore, the magnet 102a also changes with the water surface height or low. The accommodation space S moves up or down. When the water level rises, the air in the float chamber 101 can be discharged along with the vent O of the upper cover 101a to adjust the pressure in the float chamber 101.

When the liquid first flows into the preset space P from the water inlet holes W3 and W4, the water inlet holes W3, W4 and the water inlet. The holes W1 and W2 are designed to cross each other, so the liquid does not directly flow into the water inlet holes W1 and W2, the liquid system first touches the bottom surface G, and then flows into the accommodating space S through the water inlet holes W1 and W2 from the preset space P. In other words, the liquid does not directly touch the control unit 102.

The control unit 402 has a casing, and the inside of the casing is covered with a magnet (not shown), wherein the casing specific gravity is smaller than the specific gravity of the water. In this embodiment, the control unit 402 can be regarded as floating on the water surface. With the magnetic floating body, the control unit 402 moves up or down with the water level inside the liquid storage tank 404.

Please note that since the wall surfaces L1 and L2 of the float chamber 401 have a predetermined distance from the bottom surface of the liquid storage tank 404 (not shown), the water surface of the accommodation space S can be avoided by the liquid storage tank. The disturbance of the internal water level of 404 causes interference, and the height of the water level in the accommodating space S is the same as the height of the water stored in the liquid storage tank 404.

Referring to FIG. 4C, FIG. 4C is a partial enlarged view of the reed switch unit of the embodiment of the split type liquid level control device of the present invention. The reed switch unit 403 is disposed on a predetermined position on the outer side of the wall surface P1. In the embodiment, one side of one side 403a of the reed switch unit 403 has a carrier slider 403b extending in a direction D2, and a carrier slider 403c extending in a direction D2. Correspondingly, the outer side of the wall surface P1 has a groove 403d and 403e extending in the direction D2 and extending from the top end 15 of the liquid storage cylinder 404 toward the bottom surface 16 for the reed switch unit 403 to extend in the direction D2 between the grooves 403d and 403e.

In other words, when the water level in the accommodating space S is low, the magnet is close to the reed switch unit 403; when the water level in the accommodating space S is high, the magnet is away from the reed switch unit 403.

Please note that when the magnet of the control unit 402 approaches the reed switch unit 403, the magnetic reluctance of the magnet causes the reed switch unit 403 to generate a switching signal S to a rear end circuit (not shown). Therefore, the user can utilize the magnetic effective range of different magnets to adjust the distance that the magnet can activate between the reed switch units 403.

In an embodiment, the back end circuit can be implemented by a solenoid valve or a water replenishing motor, so that the magnet of the control unit 402 is close to the reed switch unit 403, and the water level of the liquid storage tank 404 is at a low water level, and the switching signal S is activated. The solenoid valve or the water replenishing motor is used for hydrating to prevent the water level from being too low; when the magnet of the control unit 402 gradually moves away from the reed switch unit 403 with the liquid level, in other words, the reed switch unit 403 has exceeded the effective range of the magnetic induction generated by the magnet. It can be regarded that the liquid level is restored to a high water level, that is, the reed switch unit 403 does not generate the switching signal S, so the solenoid valve or the hydrating motor is disabled and no longer performs the hydration action, so as to prevent the electromagnetic valve or the hydrating motor from continuously hydrating the water. Spilled from the water tank.

In another embodiment, the back-end circuit can be implemented by a warmer, and can determine whether to activate or disable the warmer according to different liquid levels, or in another embodiment, the back-end circuit can be required according to the user's requirements. It can be implemented for any load, and the rest of the operation principle is the same as the above, and for brevity, it will not be described again.

In summary, the split type liquid level control device of the present invention is activated by magnetic induction, and is passed through a mountable reed switch unit and a float chamber, so that the reed switch unit can be installed in the liquid storage according to user requirements. The outer wall of the cylinder is at any position, and the float chamber is installed at the relative position of the inner wall surface of the liquid storage tank according to the user's requirement, so that the reed switch unit can be prevented from contacting the liquid. When the reed switch unit is within the magnetic induction effective range of the control unit, the reed switch unit is activated to drive the back end circuit to operate. Moreover, the reed switch unit does not need to be disposed in the liquid or the water, and the reed switch unit can be prevented from directly contacting the liquid or the water, and the electronic components are damaged due to the moisture.
