[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] The utility model provides a side-mounted float liquid level switch. When the side-mounted float liquid level switch is used, as the liquid level in a liquid tank rises, a float plate with a magnetic plate moves upward, and under the action of the magnetic force, a rotating rod with a magnetic block on the upper side of the liquid tank moves downward, triggering a switch on the upper side of the liquid tank, thereby avoiding damage to the switch caused by the influence of the liquid when the switch is arranged inside the liquid tank, and when the switch fails, the switch structure arranged on the upper side of the liquid tank is convenient for maintenance.

[0024] Figure 1-Figure 3 The figure shows the overall structure of a side mounted float level switch of the utility model. Figure 1-Figure 3 The side-mounted float liquid level switch of this embodiment has a main body including a liquid tank 1 and a switch assembly.

[0025] A support plate 2 is provided on the upper side of the liquid tank 1, an observation window 11 is provided on the outer side of the liquid tank 1, a connecting plate 12 is provided on the upper side of the liquid tank 1, a spring 13 is provided on the upper side of the connecting plate 12, a limit plate 14 is provided on the upper side of the spring 13, a mounting plate 15 is provided on the rear side of the liquid tank 1, and a fixing hole 16 is opened on the inner side of the mounting plate 15.

[0026] The switch assembly includes a base 3 arranged on one side of the support plate 2, a fixed plate 4 is arranged on the inner side of the base 3, a rotating rod 5 is arranged on one side of the fixed plate 4, a magnetic block 6 is arranged on one side of the rotating rod 5, a trigger switch 7 is arranged on the upper side of the liquid tank 1, a floating plate 8 is arranged on the inner side of the liquid tank 1, a buoyancy block 9 is arranged on the lower side of the floating plate 8, and a magnetic plate 10 is arranged on the upper side of the floating plate 9. Specifically, in this embodiment, as the liquid level in the liquid tank 1 rises, the floating plate 8 provided with the buoyancy block 9 and the magnetic plate 10 in the liquid tank 1 moves upward, and the magnetic block 6 is attracted under the action of the magnetic force. Under the fixation of the fixed plate 4 inside the base 3, the rotating rod 5 moves downward with the magnetic block 6, pressing the trigger switch 7 on the upper side of the liquid tank 1, and the rotating rod 5 on the outer side of the liquid tank 1 is attracted by the magnetic force to press the trigger device switch downward, thereby avoiding the switch arranged in the liquid tank 1 being affected by the liquid and causing a malfunction, and at the same time facilitating routine maintenance and overhaul in case of malfunction.

[0027] Combination Figure 1-Figure 3 , a side-mounted float liquid level switch of the present embodiment is specifically used as follows: when using the side-mounted float liquid level switch, the mounting plate 15 and the outer liquid tank 1 are fixed by the fixing hole 16. As the liquid level in the liquid tank 1 rises, the floating plate 8 provided with the buoyancy block 9 and the magnetic plate 10 in the liquid tank 1 moves upward. Under the action of the magnetic force, the magnetic block 6 will be attracted. Under the fixation of the fixing plate 4 inside the base 3, the rotating rod 5 moves downward with the magnetic block 6, pressing the trigger switch 7 on the upper side of the liquid tank 1. When the liquid level drops, the floating plate 8 moves downward. After the magnetic force is reduced, the magnetic block 6 and the rotating rod 5 are reset through the limit plate 14 on the upper side of the spring 13.

[0028] In this embodiment, when the side-mounted float liquid level switch is used, it is necessary to keep the floating plate 8 stable to avoid disconnection when the switch is pressed down, which leads to instability of the switch signal. In order to have a better way to stabilize the floating plate 8, it is necessary to improve the liquid tank 1 so as to have a more stable way of pressing down the switch. For this purpose, please refer to Figure 1-Figure 3 In this embodiment, a spoiler 17 is provided inside the liquid tank 1, a liquid hole 18 is provided on the upper side of the spoiler 17, a limit strip 19 is provided inside the spoiler 17, and a limit groove 20 is provided outside the floating plate 8. In this embodiment, in order to better stabilize the triggering of the switch, when in use, the spoiler 17 inside the liquid tank 1 offsets the impact of shaking on the floating plate 8 when the liquid level is not stable, and the floating plate 8 is fixed to the limit strip 19 inside the spoiler 17 by the limit groove 20 provided on the outside, so as to avoid the shaking of the floating plate 8 and improve the stability of the rotating rod 5 and the magnetic block 6 when pressing down to trigger the switch 7.

[0029] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
