[0049] Embodiment 1

[0050] The present embodiment provides a novel vertical float ball switch, as shown in Figures 1-9As shown, comprising:

[0051] The body 11 is provided with a receiving cavity 111 and a chamber 112. The inner wall of the receiving cavity 111 is provided with positioning columns 121, which are used to cooperate with the micro switch 13. The number of the positioning columns 121 is two, and the two positioning columns 121 are diagonally arranged and horizontally extend towards the micro switch 13. The chamber 112 is open downward. The chamber 112 is specifically an internal structure of a cuboid, and the cuboid part extends into the receiving cavity 111, and the remaining part extends to the outside through the bottom surface of the receiving cavity 111.

[0052] The rocker arm 14 is accommodated in the receiving cavity 111. The rocker arm 14 is in a U shape. The rocker arm 14 rotates relative to the body 11, and the rocker arm 14 cooperates with the inner wall of the receiving cavity 111 to form rotation. The rocker arm 14 includes two legs 141, and the two legs 141 are respectively fixed with first magnets 142. The two first magnets 142 have the same polarity on the opposite faces, and the opposite faces are specifically opposite faces, for example, can be both N poles or both S poles. The two first magnets 142 are respectively located on the two sides of the outer edge wall of the chamber 112. One of the legs 141 is located on the front side, and the other leg 141 is located on the rear side.

[0053] The boom 15 is cooperated with the float ball 16 at the lower end, and when the float ball 16 moves, the boom 15 also moves. This is prior art, and will not be described. The upper end of the boom 15 extends to the chamber 112, and the upper end of the boom 15 is fixed with a second magnet 151. The second magnet 151 can be fixed on the top surface of the boom 15, or can be fixed on the part close to the top surface of the boom 15. The position of the second magnet 151 can be adjusted by the person skilled in the art according to the actual needs.

[0054] The micro switch 13 is accommodated in the receiving cavity 111, and the micro switch 13 forms a signal transmission. When the liquid reaches the preset water level, the signal transmission can control the automatic start and stop effect of the water pump. The micro switch 13 is provided with a button 132, and the position of the button 132 is on the top surface of the micro switch 13. The micro switch 13 is also provided with positioning holes 131 which cooperate with the positioning columns 121. The number of the positioning holes 131 is two, and the two positioning holes 131 are diagonally arranged. It should be noted that when the force is applied on the button 132, the button 132 will move towards the inside of the micro switch 13 to realize the signal transmission effect. Conversely, when the force applied on the button 132 disappears, the button 132 will automatically reset. This is the common sense of the micro switch 13, and will not be described.

[0055] A rocker arm 18 is housed in a receiving cavity 111. One end of the rocker arm 18 is rotatably connected to the inner wall of the receiving cavity 111, and the other end of the rocker arm 18 engages with one of the supports 141 of the rocker arm 14. Specifically, the left end of the rocker arm 18 is rotatably connected to the inner wall of the receiving cavity 111, and the right end of the rocker arm 18 engages with one of the supports 141 of the rocker arm 14. In this embodiment, the right end of the rocker arm 18 engages with the support 141 located on the front side. Alternatively, the right end of the rocker arm 18 can also engage with the support 141 located on the rear side. At this time, the rocker arm 18 is located above the button 132. When the rocker arm 18 rotates relative to the body 11, the button 132 is located on the movement trajectory of the rocker arm 18. The distance from button 132 to the point where the left end of rocker 18 rotates and connects with the inner wall of cavity 111 is L1, and the distance from the point where the left end of rocker 18 rotates and connects with the inner wall of cavity 111 to the point where the right end of rocker 18 engages with front support leg 141 is L2, where L2 > L1. By adding rocker 18 to form a lever structure, the required pressure can be reduced. Since the pressure is generated by magnetic force, the magnetic force can be reduced. On the one hand, the volume of the magnet can be reduced, thereby reducing the overall product volume and saving costs. On the other hand, since the required magnetic force is reduced, the required breaking force of float 16 switch is reduced. The breaking force of float 16 switch is determined by the weight of float 16, thus effectively reducing the volume and weight of float 16.

[0056] The float switch has a first state and a second state. In the first state, the second magnet 151 is not in the chamber 112 and does not engage with the two first magnets 142. Specifically, the first state means that the liquid level has not reached the preset level. In the second state, the second magnet 151 enters the chamber 112 and engages with the first magnets 142, driving the rocker arm 18 to press the button 132, thus stopping the water pump. Specifically, the second magnet 151 engages with the first magnet 142 located at the front. First, the rocker arm 14 fixes the two first magnets 142, which cooperate with the second magnet 151 of the boom 15 to form a compensating superposition. At the same time, the rocker arm 18 structure is added to create a lever effect, which can effectively increase the safety factor of closing the micro switch 13, making the product more reliable.

[0057] Specifically, as shown in the attached document Figures 3-7 As shown, one of the rocker arm 18 and the inner wall of the receiving cavity 111 is provided with a first rotating shaft portion 21, and the other of the rocker arm 18 and the inner wall of the receiving cavity 111 is provided with a first rotating shaft hole 22 that mates with the first rotating shaft portion 21. When the rocker arm 18 is provided with the first rotating shaft portion 21, the inner wall of the receiving cavity 111 is provided with the first rotating shaft hole 22; conversely, when the inner wall of the receiving cavity 111 is provided with the first rotating shaft portion 21, the rocker arm 18 is provided with the first rotating shaft hole 22. The rotational effect between the first rotating shaft portion 21 and the first rotating shaft hole 22 is achieved through the engagement between the two. In addition, a rotating connection can also be formed by other means.

[0058] Specifically, as shown in the attached document Figures 3-7 As shown, the inner wall of the receiving cavity 111 is provided with an even number of elastic fixing parts 17. Two elastic fixing parts 17 form a group, and each group has the same structure. For example, when there are two elastic fixing parts 17, they form a group; when there are four elastic fixing parts 17, they form two groups. In this embodiment, there are four elastic fixing parts 17, forming two groups of identical structures, which respectively cooperate with the first rotating shaft part 21. Two elastic fixing parts 17 cooperate to form a first rotating shaft hole 22 and a clamping opening 171. The clamping opening 171 communicates with the first rotating shaft hole 22 and is located above the first rotating shaft hole 22. The size of the clamping opening 171 is smaller than the size of the first rotating shaft hole 22. A first rotating shaft part 21 is disposed on the rocker arm 18. The first rotating shaft part 21 slides through the clamping opening 171 to the first rotating shaft hole 22. Because the elastic fixing parts 17 have a certain elasticity, when the first rotating shaft part 21 is fixed, it will squeeze the elastic fixing parts 17, causing the clamping opening 171 to open and form an installation. After the installation is completed, the elastic fixing parts 17 return to their original position, forming a clamping limit to prevent the first rotating shaft part 21 from falling off. In this embodiment, the clamping opening 171 has a trumpet-shaped structure. The size of the clamping opening 171 is the smallest at the position where it communicates with the first rotating shaft hole 22, and then gradually increases upwards. The clamping opening 171 forms a limiting fixation of the rocker arm 18, preventing the rocker arm 18 from falling off. In addition, the rocker 18 can be fixed by means of a hole provided in the body 11 that mates with it, or by means of a cover plate. In this embodiment, the elastic fixing part 17 is provided on the inner wall of the upper cover 20.

[0059] Specifically, as shown in the attached document Figures 3-7 As shown, the outer wall of the positioning post 121 is provided with a protruding rib 1211. The protruding rib 1211 extends from the bottom surface of the positioning post 121 towards the top surface of the positioning post 121. The number of protruding ribs 1211 can be adjusted according to actual needs; there can be one, two, three, or four. In this embodiment, there are four protruding ribs 1211, which are arranged in a circumferential array. The setting of the protruding ribs 1211 makes the micro switch 13 more stable and secure, and less prone to falling off. Here, a hot riveting process can also be used for fixation to further increase the stability of the micro switch 13 fixation.

[0060] Specifically, as shown in the attached document Figures 3-7As shown, one of the rocker arm 14 and the inner wall of the accommodating cavity 111 is provided with the second rotating shaft part 23, and the other is provided with the second rotating shaft hole 24 matched with the second rotating shaft part 23. When the rocker arm 14 is provided with the second rotating shaft part 23, the inner wall of the accommodating cavity 111 is provided with the second rotating shaft hole 24; conversely, when the inner wall of the accommodating cavity 111 is provided with the second rotating shaft part 23, the rocker arm 14 is provided with the second rotating shaft hole 24. In this embodiment, the inner wall of the accommodating cavity 111 is provided with the second rotating shaft part 23, the second rotating shaft part 23 extends horizontally towards the left side, the rocker arm 14 is provided with the second rotating shaft hole 24, the two supporting legs 141 are arranged on the two sides of the second rotating shaft part 23, and the front and back distribution is formed, and the rocker arm 14 rotates around the second rotating shaft part 23. The rocker arm 14 rotates relative to the inner wall of the accommodating cavity 111, so as to realize the rotating relationship. Here, the rotating connection mode can also increase the pin shaft fixing structure. In this embodiment, the second rotating shaft part 23 is specifically arranged on the inner wall of the base 19.

[0061] Specifically, as shown in the accompanying drawings, Figures 3-7 One of the supporting legs 141 is provided with the fixing cavity 1411, and here specifically refers to the supporting leg 141 on the front side being provided with the fixing cavity 1411. The fixing cavity 1411 opens towards the side of the micro switch 13, the right end of the flap 18 extends to the fixing cavity 1411, and the right end of the flap 18 is located on the movement track of the top surface of the inner wall of the fixing cavity 1411. The fixing cavity 1411 cooperates with the right end of the flap 18 to form the effect that the rocker arm 14 drives the flap 18 to move. Here, in the installation process, the flap 18 is installed first, and then the rocker arm 14 is installed, so as to realize the limiting and fixing of the flap 18, further form the limiting on the rotating track, and also prevent the flap 18 from falling off.

[0062] Specifically, as shown in the accompanying drawings, Figures 1-2As shown, the chamber 112 is provided with a through hole 1121, which is arranged on the part of the chamber 112 beyond the bottom surface of the accommodating cavity 111, and the through hole 1121 is in communication with the chamber 112. The hanger 15 is provided with an elastic buckle 152, which cooperates with the through hole 1121 to form a limit. Specifically, the upper and lower edges of the through hole 1121 are located on the vertical movement track of the elastic buckle 152. The size of the through hole 1121 is larger than that of the elastic buckle 152, so that the elastic buckle 152 moves vertically up and down in the through hole 1121. During installation, the elastic buckle 152 slides along the inner wall of the chamber 112, and at this time the elastic buckle 152 is deformed under pressure. When the elastic buckle 152 moves to the position of the through hole 1121, the elastic buckle 152 releases energy, so that the elastic buckle 152 extends into the through hole 1121, forming a limiting fit therebetween. At this point, the elastic buckle 152 can be deformed, and when the applied force disappears, the elastic buckle 152 will return to its original state. The arrangement of the elastic buckle 152 limits the hanger 15 from falling off, and during installation and disassembly, the elastic buckle 152 can be relied on to achieve the function of reversible deformation, which is convenient for customers to install and disassemble and maintain.

[0063] Specifically, as shown in the accompanying drawings Figures 1-2 As shown, the hanger 15 is provided with a first limiting rib 153, and the hanger 15 is fixed with a limiting piece 28 which abuts against the first limiting rib 153. The first limiting rib 153 cooperates with the limiting piece 28 to limit the limiting piece 28 from falling off. Here, the limiting piece 28 is used for limiting the float ball 16.

[0064] Specifically, as shown in the accompanying drawings Figures 1-7 As shown, the body 11 includes an upper cover 20 and a base 19, the upper cover 20 and the base 19 cooperate to form an accommodating cavity 111, the chamber 112 is arranged on the base 19, and the upper cover 20 is fixedly connected with the micro switch 13. Specifically, the positioning column 121 is arranged on the inner wall of the upper cover 20, thereby forming a connection with the micro switch 13. The rocker arm 14 is fixedly connected with the base 19, and specifically, the second rotating shaft part 23 is arranged on the inner wall of the base 19, so that the rocker arm 14 rotates relative to the base 19. The upper cover 20 is fixed with the micro switch 13, and the rocker arm 14 is fixed with the base 19, thereby isolating the part of the lead wire 30 and the movement mechanism, preventing the product from being affected during work, and the structure is simple and convenient to assemble. In this embodiment, the body 11 is a cuboid structure. The upper cover 20 and the base 19 can be sealed by a sealing strip, or can be sealed by ultrasonic welding.

[0065] Specifically, the accommodating cavity 111 and the chamber 112 are independent of each other. The accommodating cavity 111 is formed by the cooperation of the base 19 and the upper cover 20, and the accommodating cavity 111 is a closed chamber 112. The chamber 112 is arranged on the base 19, the chamber 112 is open downward, and there is no communication between the chamber 112 and the accommodating cavity 111.

[0066] Specifically, as shown in the attached document Figures 1-2 As shown, the main body 11 also has a wiring cavity 115, which communicates with the receiving cavity 111. The wiring cavity 115 is located on the upper cover 20. After the wire 30 is connected to the micro switch 13, it extends through the wiring cavity 115 to the outside. Here, the button 132 is located on the top surface of the micro switch 13, and the wiring terminal of the micro switch 13 is located below the bottom surface of the micro switch 13. The wire 30 is electrically connected to the wiring terminal, forming an upper and lower distribution. To improve the overall sealing effect, a rubber plug 29 is fixed at the connection between the wiring cavity 115 and the receiving cavity 111, and the rubber plug 29 is fitted onto the wire 30. Finally, the wiring cavity 115 is sealed by injecting glue into it.
