Description

Device for detecting float assembly

Technical Field

The application relates to the technical field of tool testing, for example to a device for detecting a floater assembly.

Background

At present, the dehumidifier includes water pump, float assembly and hall element, and float assembly is equipped with magnet, and when float assembly and hall element apart from changing, hall element can detect float assembly's position change to the interval according to float assembly and hall element changes and starts the water pump.

The float assembly is a mass production component, and because the difference of the magnet position directly influences whether the water pump can be normally started, the effective distance of the magnetic flux of the float assembly magnet must meet the product design requirement. The existing gauss meter can detect the magnetic flux of the float assembly magnet, but cannot detect the effective distance of the magnetic flux.

SUMMERY OF THE UTILITY MODEL

The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed embodiments. This summary is not an extensive overview nor is intended to identify key/critical elements or to delineate the scope of such embodiments but rather as a prelude to the more detailed description that is presented later.

The disclosed embodiments provide a device for detecting a float assembly, capable of detecting an effective distance of a magnetic flux of the float assembly.

In some embodiments, the means for detecting a float assembly comprises:

a base on which the float assembly is disposed;

the bracket is arranged on one side of the base and is provided with scales;

the magnetic control switch is arranged on the bracket and can move relative to the floater component;

the power supply is connected with the magnetic control switch;

the prompting device is connected with the magnetic control switch and the power supply in series to form a loop;

under the condition that the magnetic control switch moves towards the floater component, the loop is conducted, and the prompting device is started; and when the magnetic control switch moves away from the floater component, the loop is disconnected, and the prompting device is closed.

The device for detecting the float assembly provided by the embodiment of the disclosure can realize the following technical effects:

when the magnetic control switch moves towards the floater component, the distance between the magnetic control switch and the floater component is reduced. Because the magnet is arranged in the float assembly, the distance between the magnetic control switch and the magnet is also reduced. When the distance between the magnet and the magnetic control switch reaches a first threshold value, the magnetic control switch detects a magnetic field, so that the loop is conducted, and the device is prompted to be started. The first scale value can be obtained through the scale of the bracket. When the magnetic control switch moves away from the floater component, the distance between the magnetic control switch and the floater component is increased, and the distance between the magnetic control switch and the magnet is also increased. When the distance between the magnet and the magnetic control switch reaches a second threshold value, the magnetic field detected by the magnetic control switch becomes zero, so that the loop is disconnected, and the prompting device is closed. The second scale value can now be obtained by means of the scale of the holder. The first threshold value is the distance between the magnetic control switch and the magnet when the magnetic field detected by the magnetic control switch is changed from zero to non-zero, and the second threshold value is the distance between the magnetic control switch and the magnet when the magnetic field detected by the magnetic control switch is changed from non-zero to zero. Therefore, the effective distance of the magnetic flux of the floater assembly is obtained according to the difference value of the first scale value and the second scale value.

The foregoing general description and the following description are exemplary and explanatory only and are not restrictive of the application.

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

As shown in fig. 1 and 2 in conjunction, embodiments of the present disclosure provide a device for detecting a float assembly. The float assembly 1 is provided with a magnet (not shown in the figures). The device comprises a base 2, a bracket 3, a magnetic control switch 4, a power supply 5 and a prompting device 6. The base 2 is provided with a float assembly 1. The bracket 3 is arranged on one side of the base 2 and is provided with scales. The magnetic switch 4 is arranged on the bracket 3 and can move relative to the floater assembly 1. Referring to fig. 2, a power supply 5 is connected to the magnetic switch 4. The prompting device 6 is connected with the magnetic control switch 4 and the power supply in series to form a loop. Under the condition that the magnetic control switch 4 moves towards the floater component 1, the loop is conducted, and the prompting device 6 is started; in case the magnetically controlled switch 4 moves away from the float assembly 1, the circuit is open, indicating that the device 6 is closed. The power supply supplies power to the prompting device.

With the device for detecting the float assembly provided by the embodiment of the disclosure, when the magnetic control switch moves towards the float assembly, the distance between the magnetic control switch and the float assembly becomes smaller. Because the magnet is arranged in the float assembly, the distance between the magnetic control switch and the magnet is also reduced. When the distance between the magnet and the magnetic control switch reaches a first threshold value, the magnetic control switch detects a magnetic field, so that the loop is conducted, and the device is prompted to be started. The first scale value can be obtained through the scale of the bracket. When the magnetic control switch moves away from the floater component, the distance between the magnetic control switch and the floater component is increased, and the distance between the magnetic control switch and the magnet is also increased. When the distance between the magnet and the magnetic control switch reaches a second threshold value, the magnetic field detected by the magnetic control switch becomes zero, so that the loop is disconnected, and the prompting device is closed. The second scale value can now be obtained by means of the scale of the holder. The first threshold value is the distance between the magnetic control switch and the magnet when the magnetic field detected by the magnetic control switch is changed from zero to non-zero, and the second threshold value is the distance between the magnetic control switch and the magnet when the magnetic field detected by the magnetic control switch is changed from non-zero to zero. Therefore, the effective distance of the magnetic flux of the floater assembly is obtained according to the difference value of the first scale value and the second scale value.

Optionally, the magnetically controlled switch 4 is disposed directly above the float assembly 1. Therefore, the distance between the magnetic control switch and the floater component along the extension direction of the bracket is minimum, and the detection efficiency can be improved.

Optionally, the prompting device 6 comprises a lamp 61 or a buzzer (not shown in the figures).

When the prompting device is a lamp, the loop is conducted under the condition that the magnetic control switch moves towards the floater component, and the lamp is lightened to realize the starting of the prompting device due to the fact that the power supply supplies power to the prompting device. And under the condition that the magnetic control switch moves away from the floater component, the circuit is disconnected, and the lamp is turned off to realize the closing of the prompting device.

When the prompting device is a buzzer, the loop is conducted under the condition that the magnetic control switch moves towards the floater component, and the buzzer buzzes to realize the starting of the prompting device as the power supply supplies power to the prompting device. Under the condition that the magnetic control switch moves away from the floater component, the loop is disconnected, and the buzzer mutes to realize the closing of the prompting device.

Alternatively, the lamp 61 is arranged horizontally with the scale. Like this, when suggestion device is the lamp, under the condition that the lamp becomes bright, the lamp has the effect of illuminating to the scale value rather than the level setting to convenience of customers looks over the scale that corresponds when the lamp becomes bright, and is visual good.

Optionally, the carriage 3 comprises a vernier caliper 31. The vernier caliper 31 is fixedly arranged on the base 2 and is perpendicular to the base 2. Since the precision of the vernier caliper is typically 0.05 mm and 0.02 mm. The scale of the vernier caliper reflects the precision of the vernier caliper, and a user can obtain a relatively accurate numerical value by reading the scale value. Meanwhile, the vernier caliper is fixedly arranged on the base and is perpendicular to the base. Therefore, under the condition that the prompting device is a lamp, the lamp moves along the direction parallel to the vernier caliper, and the position of the lamp and the position of the vernier caliper are prevented from being deviated.

Optionally, as shown in connection with fig. 1, the bracket 3 further comprises a first bracket 32. The first bracket 32 is disposed on one side of the vernier caliper 31 and above the base 2. The first bracket 32 is provided with a magnetic switch 4, a prompting device 6 and a power supply 5, and can move towards or away from the floater assembly 1 along the vernier caliper 31. Therefore, the magnetic control switch, the prompting device and the power supply are arranged on one side of the vernier caliper through the first support.

Alternatively, as shown in fig. 1, the first bracket 32 includes a bracket main body 32a and a fixing member 32 b. The fixing member 32b is provided inside the holder main body 32a, and fixes the magnetic switch 4 to the holder main body 32a in a direction parallel to the base 2. Therefore, the magnetic control switch is fixed on the support main body along the direction parallel to the base through the fixing piece, so that the magnetic control switch is perpendicular to the floater component, and the floater component is prevented from deviating relative to the base.

Optionally, the first bracket 32 further includes a sliding portion 32 c. The sliding portion 32c is slidably provided in the caliper 31, and fixes the holder body 32a to the side surface of the caliper 31. Thus, the sliding part is operated, so that the bracket main body slides along the extending direction of the vernier caliper, and the relative movement of the magnetic control switch and the float component is realized.

Optionally, the sliding portion 32c includes a clamp 321 c. The holding member 321c is fitted to the caliper 31, and holds the holder body 32a to the caliper 31.

Optionally, the sliding portion 32c further includes a knob 322 c. The knob 322c is disposed on a side surface of the clamping member 321c, and is used for fastening the clamping member 321c to the vernier caliper. In this way, the clamp can be clamped to the caliper by operating the knob. Meanwhile, the clamping piece can be separated from the vernier caliper by operating the knob, so that the magnetic control switch moves relative to the floater component.

Optionally, the base 2 comprises an inspection platform 2a and a support column 2 b. The detection platform 2a is arranged perpendicular to the extending direction of the vernier caliper 31. The detection platform 2a is disposed at the bottom of the vernier caliper 31. The support column 2b is provided on one side of the bracket 3. The support column 2b is arranged in parallel with the bracket 3.

Optionally, the base 2 further comprises a jaw 21b and a sleeve 211 b. One end of the clamping jaw 21b is sleeved on the outer wall of the supporting column 2b through a sleeve 211b, and the other end clamps the vernier caliper 31. Therefore, the vernier caliper is stably fixed on the base, and the stability of the vernier caliper is improved.

Alternatively, the magnetically controlled switch 4 is a hall switch. The Hall switch is an active electric conversion device, is manufactured by utilizing the principle of Hall effect and integrated packaging and assembling processes, and can convert a magnetic signal into an electric signal. Meanwhile, the Hall switch has high sensitivity and reliability. Therefore, the change of the relative position of the Hall switch and the magnet of the floater component can be reflected by the connection or disconnection of the Hall switch, and the connection or disconnection of the Hall switch causes the connection or disconnection of the loop, so that the prompting device is switched on or off, and the scale value of the support is acquired according to the prompt of the prompting device.
