[0031] Referring to Figures 1 to 4, it can be conceived that exhaust holes 123 are provided at the upper ends of the first chamber 121 and the second chamber 122. When the water level is higher than the lower end of the outer cover 120, the air in the first chamber 121 and the second chamber 122 can be discharged from the exhaust holes 123. Among them, the opening direction of the exhaust holes 123 faces the side of the base 110, and the base 110 is provided with an extension plate 113, and the projection plane of the exhaust holes 123 is located on the extension plate 113. At this time, the water flowing down from above can be blocked by the extension plate 113, preventing the water from flowing through the exhaust holes 123 and contacting the positive electrode 210 and the negative electrode 220 at the same time to conduct the circuit, ensuring the smooth progress of the work and improving the stability and reliability of the work.

[0032] In this embodiment, the outer cover 120 is provided with a cable connector 124, the cable 310 is passed through the cable connector 124, the cable 310 is connected to the cable connector 124 by potting, and an outer cover 125 is sleeved on the cable connector 124.

Finally, the outer cover 125 is sleeved on the cable connector 124 to improve the overall aesthetics. Further, a sealing head 126 is arranged between the cable connector 124 and the cable 310, a compression ring 127 is arranged above the sealing head 126, and the outer cover 125 is crimped on the compression ring 127 and fixedly connected to the cable connector 124. By adopting the above structure, the sealing performance between the cable connector 124 and the cable 310 can be further improved, and the safety can be improved. It can be conceived that the cable connector 124 and the outer cover 125 are connected by threads, which can make the connection between the cable connector 124 and the outer cover 125 more stable.

[0033] Refer to Figure 1 , Figure 2 and Figure 4 , in some embodiments, installation lugs 114 are provided on both sides of the base 110, and the installation lugs 114 are used for passing a lifting rope. During fixation, a lifting rope can be tied to the installation lugs 114, and the liquid level control device can be fixedly installed on other components through the lifting rope. The structure is simple and the operation is convenient. Of course, the lifting rope can be set as an elastic rope. At this time, the two ends of the elastic rope can be tied to the installation lugs 114 in advance, and then the elastic rope is stretched elastically to be sleeved on other components, so as to realize the fixed installation of the liquid level control device and improve the firmness of the fixation.

[0034] Refer to Figure 1 , Figure 2 and Figure 4, in some embodiments, the base 110 is provided with a mounting bracket 140. At this time, the mounting bracket 140 is connected to other components to achieve the fixed installation of the liquid level control device. Among them, the base 110 and the mounting bracket 140 are slidably matched, so that the base 110 can move up and down relative to the mounting bracket 140. Specifically, the mounting bracket 140 is provided with a guide plate 141, the base 110 is provided with a mounting block 115, the mounting block 115 is provided with a sliding groove 116, and the guide plate 141 is connected in cooperation with the sliding groove 116. During installation, the mounting bracket 140 is fixed to other components, and then the guide plate 141 is slid along the sliding groove 116, so as to connect the base 110 and the mounting bracket 140, making the installation simple, improving work efficiency, and at the same time, the position of the base 110 can be adjusted by the up and down sliding between the base 110 and the mounting bracket 140, so as to realize the height adjustment of the liquid level control device, meet the usage requirements of different users, and expand the scope of application.

[0035] Furthermore, the guide plate 141 is vertically provided with a plurality of clamping positions 142, the sliding groove 116 is provided with a clamping block 117, and the clamping block 117 is clamped and fixed with the clamping positions 142.

During installation, the guide plate 141 extends into the sliding groove 116. At this time, the rib 143 is matched with the notch 118, and then the clamping block 117 is clamped with the clamping position 142 to realize the connection between the base 110 and the mounting bracket 140, with a simple structure and convenient operation.

[0036] It can be imagined that the guide plate 141 is provided with a limiting hole 144 below the clamping position 142. The limiting hole 144 is located on both sides of the rib 143, and a limiting member 145 is inserted into the limiting hole 144. The limiting member 145 can abut against the mounting block 115. During the use process, when the clamping block 117 accidentally disengages from the clamping position 142, the base 110 will slide down along the guide plate 141. At this time, by providing the limiting member 145, the limiting member 145 abuts against the mounting block 115 after the base 110 slides down to limit the sliding displacement of the base 110, so as to prevent the liquid level control device from sliding down and colliding with other accessories and being damaged, and at the same time, it can also ensure the stability and reliability of the work.

[0037] In some embodiments, the control unit 300 is provided with a Bluetooth module, and the Bluetooth module is used to receive instructions issued by the mobile terminal. Specifically, the user can operate through the mobile terminal. At this time, the Bluetooth module receives the operation instructions issued by the mobile terminal, so as to realize the control of the liquid level control device and achieve intelligent operation to meet the user's needs.

[0038] It should be noted that the operation of the control unit 300 can also be achieved by other means such as a remote controller. Those skilled in the art can make a reasonable selection according to the actual situation, and this application does not limit this.
