As shown in fig. 1 to 5, a float switch of the present embodiment, which is easy to assemble, comprises a bracket member 1 and a float 2, a sliding assembly capable of sliding connection between the bracket member 1 and the float 2 is provided between them,

specifically, a magnet is installed on the float 2, the top end or the bottom end of the bracket component 1 is positioned close to a magnetic force induction action device in the electrical equipment, when the water level in the electrical equipment reaches the highest position or the lowest position, the float 2 floats upwards or descends along with the change of the water level, so that the change of the water level can cause the magnetic force between the magnet on the float and the magnetic force induction action device to generate induction action, and the water level condition of the electrical equipment can be judged by detecting the signal change of the magnetic force induction action device;

when the magnet of the float approaches the magnetically sensitive actuation means, the magnetically sensitive actuation means will emit a signal indicating that the float has reached a specific water level position, which signal can be received and processed in order to take corresponding control measures, such as a switching device or a warning.

Specifically, when the bottom end of the bracket component 1 is positioned close to a magnetic force induction action device in the electrical equipment, the float switch detects the lowest water level in the electrical equipment, and when the water level is lowered to the lowest position, the float 2 descends to the bottom of the bracket component 1, so that the magnet on the float 2 and the magnetic force induction action device perform induction action, and a signal of the lowest water level is detected;

when the top end of the bracket component 1 is positioned close to a magnetic force induction action device in the electrical equipment, the float switch detects the highest water level in the electrical equipment, and when the water level rises to the highest position, the float 2 floats to the top of the bracket component 1, so that the magnet on the float 2 and the magnetic force induction action device perform induction action, and a signal of the highest water level is detected.

As shown in fig. 1 to 5, the moving direction of the float 2 of the present embodiment is perpendicular to the sensing surface on the magnetic force sensing action means, which means that when the magnet on the float 2 approaches the magnetic force sensing action means, there is a perpendicular relationship between the sensing surface of the magnetic force sensing action means and the moving direction of the float 2.

This design helps to ensure the accuracy and reliability of the detection of the float switch, and when the position of the float 2 changes, such as floating or falling, the change in magnetic force between the magnet on the float 2 and the sensing surface of the magnetically induced action means will be detected, as the sensing surface of the magnetically induced action means is perpendicular to the direction of movement of the float 2, this design allows to more accurately sense the position of the float 2 and accurately detect the change in water level.

As shown in fig. 1 to 5, the bracket member 1 of the present embodiment includes at least two support brackets 11, the two support brackets 11 are disposed opposite to each other, a hollow portion 12 is formed between the two support brackets 11, the float 2 is located in the hollow portion 12,

preferably, the number of the supporting brackets 11 can be adjusted according to actual requirements, but at least two supporting brackets 11 are provided, and the supporting brackets 11 are oppositely arranged at a certain interval and can be parallel or arranged at an angle;

in the present embodiment, a hollow portion 12 is formed between two support brackets 11, and the float 2 moves up and down in this hollow portion 12 through the sliding assembly and the support brackets 11;

this design provides a degree of flexibility in that the relative arrangement of the support brackets 11 allows the float 2 to move freely vertically or horizontally within the hollowed out portion 12, such a configuration enabling the float switch to accommodate different water level ranges and provide accurate measurements and detection as the water level changes.

As shown in fig. 1 to 5, the sliding assembly of the present embodiment includes a sliding portion provided on each support bracket 11 and a plurality of sliding grooves 21 provided on the float 2, the sliding portions being in one-to-one correspondence with the sliding grooves 21;

When the sliding groove 21 on the float 2 and the sliding portion on the support bracket 11 correspond to each other, the float 2 can slide vertically with respect to the bracket member 1, and this design allows the float 2 to float up or down freely according to the change of the water level while maintaining the connection with the bracket member 1.

Through the design of the sliding component, the floater 2 can slide stably in the vertical direction under the guidance of the bracket component 1, so that the change of the water level is accurately perceived, the abrasion and friction between the components are reduced, and the reliability and durability of the floater switch are improved.

As shown in fig. 1 to 5, the sliding portion of the present embodiment is a frame body supporting the bracket 11; that is, the structure of the support bracket 11 itself has a characteristic of being slidably connected to the float 2.

Specifically, the frame body of the support bracket 11 has a shape or structure corresponding to the sliding groove 21 on the float 2, so that when the float 2 floats up or descends at the time of water level change, sliding connection is formed between the sliding groove 21 on the float 2 and the frame body of the support bracket 11, and the sliding groove 21 is tightly fitted with the frame body, so that the float 2 can vertically slide under the guidance of the frame body.

As shown in fig. 1 to 5, the bracket component 1 of the present embodiment further includes a base 13, one ends of the two support brackets 11 are both disposed on one side of the base 13 away from the magnetic force induction action device, and the other side of the base 13 is close to the magnetic force induction action device; specifically, the base 13 serves to provide support and stability of the entire system, and one end of two support brackets 11 is connected to one side of the base 13.

By connecting one end of the support bracket 11 with the base 13, the bracket member 1 can be made stronger and more stable, the presence of the base 13 can increase the supporting force of the whole system and provide additional structural support, and at the same time, the one end of the support bracket 11 is connected to the side of the base 13 away from the magnetic force induction action device, so that the interference of magnetic force induction can be reduced to the greatest extent.

Meanwhile, the other side of the base 13 is close to the magnetic induction action device, and the purpose of the design is to utilize the base 13 as a close area of the magnetic induction action device so as to improve the effect of magnetic induction, and the magnetic induction action device can sense the change of the water level according to the position and the movement of the floater 2 and provide accurate measurement results.

With this arrangement, the support bracket 11 can be firmly fixed to the base 13 while minimizing interference of magnetic force induction and ensuring that the magnetic force induction actuating device can accurately sense the position change of the float 2. Thus, reliable water level control and monitoring functions can be achieved.

Preferably, an opening communicated with the hollowed-out part 12 is formed between the other ends of the two support brackets 11 in the embodiment, so that the floater 2 is conveniently clamped in the hollowed-out part 12;

specifically, the hollow portion 12 is a space between the two support brackets 11, and is used for accommodating the float 2, and in order to ensure that the float 2 can be easily clamped into the hollow portion 12, an opening communicated with the hollow portion 12 is formed between the other ends of the two support brackets 11;

Through the design above, the system has realized the tight connection between float 2 and support frame 11, has guaranteed accurate water level control and monitoring, and the existence of opening makes float 2 can easily get into fretwork portion 12, has simplified the assembly process, has ensured the stable connection of float 2 and support frame 11 to the reliability of entire system has been improved.

As shown in fig. 1 to 5, the base 13 of the present embodiment is provided with a limit protrusion 131 extending toward the other end of the support bracket 11, and the limit protrusion 131 is used as a part of the base 13, and functions to limit the maximum displacement range of the float 2 during the movement of the float 2, and avoid the situation that the float 2 is displaced on the support bracket 11, which helps to avoid the position of the float 2 exceeding the predetermined range, thereby ensuring the normal operation and accuracy of the system.

Specifically, when the float switch detects the lowest water level in the electrical equipment, at this time, when the water level drops to the lowest position, the float 2 drops to the bottom of the bracket component 1, at this time, the limiting protrusion 131 is close to or offset against the outer side wall of the float 2, so as to limit the position of the float 2, ensure that the magnet can be opposite to the sensing surface of the magnetic force sensing action device, and ensure the accuracy of detection.

As shown in fig. 1 to 5, a reinforcing rib 132 is provided between the base 13 and each support bracket 11 in the present embodiment, so as to increase the stability and bearing capacity of the support bracket 11.

By the presence of the reinforcing ribs 132, a firm connection is formed between the base 13 and the support bracket 11, which can effectively support and withstand the action of external forces, which can improve the structural strength and stability of the entire bracket part 1, so that it can better resist the interference of vibration, shock or other external forces.

Preferably, the number and location of the ribs 132 can be adjusted to meet the requirements of the connection between the reinforcing support bracket 11 and the base 13, and they are generally designed as a strong and durable material to ensure stable support under a variety of operating conditions.

Thus, in the present embodiment, the reinforcing ribs 132 are used to strengthen the connection between the base 13 and the support bracket 11, improving the stability and structural strength of the system.

Preferably, in this embodiment, the reinforcing ribs 132, the support bracket 11, and the base 13 are integrally formed, and they may be manufactured and installed as a single body.

In particular, the reinforcing bars 132, the support bracket 11 and the base 13 may be formed by an advanced integral molding process, such as injection molding or casting, which means that they may be manufactured simultaneously to form a single component.

The integrally formed arrangement has many advantages, firstly, it provides higher structural strength and stability because there is no joint or seam, reducing the risk of loosening or falling off, and secondly, the integrally formed arrangement simplifies the manufacturing process and improves the production efficiency, reduces the number of parts and the assembly process, and reduces the production cost.

Through the integrated into one piece setting of strengthening rib 132, support frame 11 and base 13, can ensure that they coordinate the motion and firmly connect in the use, improve holistic stability and reliability.

Thus, in this embodiment, the integrally formed arrangement of the stiffener 132, support bracket 11 and base 13 enables them to be interconnected in a stronger, more efficient manner, providing a stable and reliable support structure for the system.

Preferably, in this embodiment, the reinforcing ribs 132, the supporting bracket 11, and the base 13 are made of elastic materials, and have a certain elasticity;

further, the elastic material generally has rebound ability, i.e. can recover to an original shape after being subjected to an external force, and the elastic property can provide a certain flexibility and shock absorption capability in application;

by using an elastic material for the reinforcing ribs 132, the support bracket 11 and the base 13, it is possible to provide a certain buffering and shock absorbing effect in response to external force or vibration, which helps to protect the stability of the system and reduce external factors that may cause damage or interference.

In addition, the elastic material can provide certain self-adaptability and adapt to different strains and deformations, so that the support bracket 11 and the base 13 can better adapt to the changes in practical application scenes.

Therefore, in the present embodiment, the reinforcing ribs 132, the support bracket 11 and the base 13 are made of an elastic material, and have a certain elasticity to provide flexibility, shock absorbing capability and self-adaptation of the system, which helps to increase the stability and reliability of the system.

Furthermore, the use of an elastic material not only provides elasticity and shock absorbing ability, but also helps the float 2 to be caught from the opening into the hollowed-out portion 12 between the support brackets 11.

The hollowed-out design has no obstruction of the old shell body, so that the floater moves along with the change of the water level more easily.

Since the elastic material has a certain flexibility and deformability, it can be appropriately deformed by an external force, so that the floats can be easily caught between the supporting brackets 11 through the openings.

When the floats gradually move and approach the openings of the support brackets, the flexibility of the elastic material enables the support brackets to slightly deform, creating a suitable gap for the floats to smoothly slide into between the support brackets; after the floats are assembled in the hollow parts 12, the supporting brackets 11 are elastically restored and clamped into the corresponding sliding grooves 21;

the use of such an elastic material ensures a proper fit between the float and the support bracket, making the connection between the float and the bracket more secure and without the problem of jamming or seizing due to excessive tightness.

Thus, in this embodiment, the use of an elastic material not only provides elasticity and shock absorbing capability, but also serves a convenient function when the float is caught between the support brackets 11 from the opening. They are able to accommodate the movement of the floats and ensure the smooth insertion and connection of the floats.

As shown in fig. 1 to 5, a limiting component is arranged on one end of the bracket component 1 far away from the magnetic induction action device, and is used for limiting the floater 2 on the bracket component 1;

when the float 2 approaches or reaches the set limit position, the stop assembly will act to prevent further movement of the float 2, thereby limiting it to the frame member 1, preventing it from falling out of the frame member 1, which ensures that the float 2 remains stable in place and prevents it from falling out of or beyond the required working range.

Preferably, the limiting assembly in this embodiment includes limiting barbs 14 provided on the end of each support bracket 11, each of the limiting barbs 14 being bent inward; the design of the limit barb 14 is such that it can provide the function of limiting the position of the float 2 on the bracket part 1, by means of the inward bending of the barb, when the float 2 approaches or reaches the limit position, it will come into contact with the limit barb 14, the curved shape of the barb ensuring that the float 2 is limited after contact and will not continue to move.

Further, the curved design of the limit barbs 14 can be adjusted according to specific requirements to provide proper limit force and position control that will ensure that the float 2 remains within the desired operating range at all times, avoiding deviation from or exceeding the allowable range.

Further, by using the limiting barb 14 as a limiting component, the limitation of the position of the float 2 can be simply and effectively realized, and the stable fixation of the float on the bracket component 1 can be ensured.

Preferably, each of the limiting barbs 14 in this embodiment is provided with a limiting plane 142, and the limiting plane 142 can prop against the float 2 to prevent the float 2 from being separated from the bracket component 1.

The limiting plane 142 is a part of the limiting barb 14, is positioned at the tail end of the barb and is in contact with the floater 2, and when the floater 2 approaches or reaches the limiting position, the limiting plane 142 can collide with the floater 2 to form resistance for preventing the floater 2 from moving continuously;

through the interaction of spacing plane 142 and float 2, can prevent effectively that float 2 from deviating from support part 1, spacing plane 142's design and position design according to specific needs provide reliable spacing function.

By using a stop barb 14 with a stop plane 142, it is ensured that the float 2 is firmly fixed to the frame part 1, avoiding its disengagement or exceeding the desired position.

Preferably, each of said support brackets 11 is arranged vertically on the base 13 so as to bring the float 2 to a horizontal condition on the bracket member 1, ensuring that the float 2 remains substantially horizontal; by providing the support brackets 11 vertically, a stable support foundation is provided, which are mounted vertically on the base 13, ensuring a correct positioning between the float 2 and the bracket part 1.

Further, the purpose of maintaining the float 2 in a level condition is to ensure that the measurements or work of the float 2 can be accurately performed, the level condition of the float 2 being important for certain applications, particularly where accurate level measurements are required.

Through vertical support 11 that sets up on base 13, can guarantee that float 2 roughly keeps the horizontality on support part 1, this can provide accurate horizontal reference, ensures that float 2 carries out work on the horizontal position, adopts such design, can make the magnet of float 2 just to the sensing surface of magnetic force response action device, ensures the response distance between the two, avoids the two condition that takes place to respond to poorly, ensures electrical equipment's steady operation, improves user experience.
