Description

Technical Field

[0001] The utility model relates to the technical field of gas volume detection devices, and specifically relates to a detection device for a filtering device. Background Art

[0002] During the production process of gas or liquid filtering devices on the market, it is necessary to monitor their flux to ensure that there are no foreign objects blocking the pipelines inside the products and to ensure that the flux of the products leaving the factory reaches the specified value. If users purchase and use gas or liquid filtering devices with insufficient flux, it will directly affect the user experience. To prevent filtering devices with insufficient flux from flowing into the market, the applicant designs a detection device for a filtering device. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a detection device for a filtering device, which monitors the flux of the filtering device after being powered on through a flux monitor, determines whether the filtering device is a qualified product, prevents filtering devices with insufficient flux from flowing into the market, and avoids users from purchasing and using unqualified products.

[0004] The purpose of the utility model is realized as follows:

[0005] A detection device for a filtering device includes a machine base for detachably installing the filtering device and a flux monitor for detecting the flux of the filtering device. A power supply module for electrically connecting with the filtering device is arranged on the machine base. The filtering device is positioned on the machine base, and a conveying pipe assembly for conveying gas or liquid is arranged between the filtering device and the flux monitor. When the power supply module supplies power to the filtering device, the gas or liquid generated by the operation of the filtering device enters the flux monitor through the conveying pipe assembly to detect the flux of the filtering device.

[0006] After the filtering device is only placed on the machine base and powered on, the gas or liquid output by the filtering device enters the flux monitor through the conveying pipe assembly. The tester can observe the gas volume value of the flux monitor to determine whether the filtering device is a qualified product, prevent filtering devices with insufficient flux from flowing into the market, and avoid users from purchasing and using unqualified products.

[0007] A positioning tooling for clamping and positioning the filtering device is arranged on the machine base, and the filtering device is detachably positioned and installed on the positioning tooling. When the filtering device is detected, it is clamped on the machine base through the positioning tooling. After the filtering device is detected, the positioning tooling releases the filtering device.

[0008] A movable conductive switch is arranged on the machine base. A power connection part electrically connected to the power supply module is arranged on the conductive switch, and the power connection part moves with the conductive switch. A conductive terminal for conducting electricity is arranged on the filtering device. When the conductive switch moves to the open position, the power connection part is disconnected from the conductive terminal. When the conductive switch moves to the closed position, the power connection part is conductively connected to the conductive terminal, and the filtering device operates with power.

[0009] The conductive switch is switched between the open position state and the closed position state through movement; when the filtering device is positioned on the base and detected, when the conductive switch is switched from the open position state to the closed position state, the power connection part acts on the conductive terminal of the filtering device;

[0010] When the filtering device finishes the detection, the conductive switch is switched from the closed position state to the open position state, and the power connection part does not act on the conductive terminal of the filtering device.

[0011] When the filtering device is placed on the base, the conductive switch needs to move to enable the conductive detection of the filtering device. On the one hand, it avoids the wrong installation of the filtering device on the base by the tester. On the other hand, when the filtering device does not need to be detected, the conductive switch is in the open position state, which is safe to operate, and when the conductive switch is in the open position state, it is easy to place the filtering device on the base.

[0012] The positioning tooling is movably arranged on the base, and a vibration motor acting on the positioning tooling is also provided on the base; during detection, the vibration motor is electrically connected to the power supply module and drives the filtering device to vibrate through the positioning tooling to detect whether foreign objects are accidentally placed in the conveying cavity of the filtering device.

[0013] A microswitch is arranged on the base, and the microswitch is electrically connected in the circuit between the power connection part and / or the vibration motor and the power supply module; during detection, the microswitch is closed, and the circuit between the vibration motor and the power connection part and / or the power supply module is conducted.

[0014] The conductive switch is rotatably arranged on the base. A microswitch for controlling the on-off of the detection circuit is provided on the base. The power connection part and the microswitch are respectively conductively connected to the power supply module through wires and form a detection circuit acting on the filtering device; the conductive switch rotates to the open position state or the closed position state to control the on-off of the internal circuit of the microswitch;

[0015] When the filtering device is positioned on the base and detected, the conductive switch rotates to the closed position state and acts on the microswitch, and the internal circuit of the microswitch is in a connected state, and the detection circuit is in a connected state;

[0016] When the filtering device finishes the detection, the conductive switch rotates to the open position state, the internal circuit of the microswitch is in a disconnected state, and the detection circuit is in a disconnected state.

[0017] When the filtering device is positioned on the base and detected, the microswitch, the vibration motor, the power supply module, the adjustment module, and the conductive switch form a detection circuit for detecting the filtering device.

[0018] The conductive switch needs to rotate to the closed position state to make the control detection circuit connected, which has the characteristic of safe operation.

[0019] During the filling process of the filtering device, foreign objects may accidentally fall into the inside of the conveying cavity of the filtering device, thereby affecting the product throughput. In order to further detect whether there are foreign objects in the conveying cavity, a vibration motor is set to make the filtering device vibrate. During the vibration process, the foreign objects that accidentally fall into the inside of the conveying cavity will most likely block the outlet end of the conveying cavity, resulting in a decrease in the reading of the throughput monitor. Therefore, it can be determined whether there are foreign objects in the conveying cavity through the reading of the throughput monitor, so as to screen out unqualified filtering devices, prevent unqualified filtering devices from flowing into the market, and avoid users from purchasing unqualified products.

[0020] An adjustment module for adjusting the vibration frequency of the vibration motor is provided on the machine base. The adjustment module includes a potentiometer wire-connected to the power supply module through a wire, and an adjustment knob is rotatably provided on the potentiometer.

[0021] The machine base includes a bottom plate, and the positioning tooling is elastically floating relative to the bottom plate; a spring is provided between the bottom plate and the positioning tooling, and the positioning tooling is supported on the bottom plate through the spring.

[0022] The conveying pipe assembly includes a filter. The inlet end of the filter is connected to the outlet end of the filtering device, and the outlet end of the filter is connected to the throughput monitor; a filter pipe extending vertically and communicating with the inlet end of the filter is provided in the inner cavity of the filter, and a falling-back area is formed between the filter pipe and the inner cavity of the filter. During detection, the foreign objects entering the conveying pipe assembly finally enter the inner cavity of the filter through the filter pipe and are concentrated in the falling-back area.

[0023] A filter pipe extending vertically and disconnected from the outlet end of the filter is provided on the filter; a falling-back area is formed between the outer side of the filter pipe and the inner cavity of the filter. During the detection of the filtering device, the foreign objects in the conveying cavity of the filtering device are conveyed to the filter pipe under the action of pressure, and then enter the falling-back area under the action of gravity.

[0024] If there are foreign objects in the conveying cavity and the particle size of the foreign objects is small enough (it can enter the conveying pipe assembly), the foreign objects will be blown into the filter. The foreign objects enter the inner cavity of the filter through the filter pipe and finally fall back uniformly on the falling-back area, preventing foreign objects from existing on the conveying pipe assembly during the detection of the next filtering device, thereby avoiding affecting the detection result of the throughput monitor and preventing the detection result from deviating.

[0025] The outlet end of the filter is misaligned with the filter pipe; the filter is made of a transparent material, or a perspective observation window for observing the internal condition of the falling-back area is provided on the filter.

[0026] The filter includes an upper shell and a lower shell. A connecting part is provided between the upper shell and the lower shell, and the upper shell and the lower shell are detachably connected and matched through the connecting part; when the upper shell and the lower shell are disassembled, the falling-back area is opened, so that the foreign objects in the filter can be taken out.

[0027] A spring is provided between the bottom plate and the positioning plate. One end of the spring is fixed on the bottom plate, and the other end of the spring is fixedly connected to the positioning plate. The bottom plate elastically supports the positioning plate through the spring, and the positioning plate is flexibly connected to the bottom plate through the spring, facilitating the vibration motor to drive the filtering device to vibrate through the tooling assembly.

[0028] The beneficial effects of the present utility model are as follows:

[0029] The flux of the filtering device after being powered on is monitored by a flux monitor to determine whether the filtering device is a qualified product, preventing filtering devices with insufficient flux from flowing into the market and avoiding users from purchasing and using unqualified products.

When the power supply module 4 supplies power to the filtering device 2, the gas or liquid (filtered gas or liquid) generated by the operation of the filtering device 2 enters the flux monitor 3 through the conveying pipe assembly 5 to detect the flux of the filtering device 2.

[0037] When the filtering device 2 is being tested on the machine base 1, the filtering device 2 only needs to be placed on the machine base 1 and powered on. Then, the gas or liquid output by the filtering device 2 enters the flux monitor 3 through the delivery pipe assembly 5. By observing the gas volume value of the flux monitor 3, it can be determined whether the filtering device 2 is a qualified product, preventing filtering devices 2 with insufficient flux from entering the market and avoiding users from purchasing and using unqualified products.

[0038] In this embodiment, the flux monitor 3 is a prior art device. It includes a transparent tube with scale values, and a floating ball is provided inside the transparent tube. One end of the transparent tube is connected to the delivery pipe assembly 5.

[0042] A movable conductive switch 7 is provided on the machine base 1. The conductive switch 7 is provided with an electricity connection part 8 for making conductive connection with the conductive terminal 9 of the filtering device 2. When the filtering device 2 is placed on the machine base 1, the conductive switch 7 needs to move to conduct a conductivity test on the filtering device 2. On the one hand, it avoids the tester from wrongly installing the filtering device 2 on the machine base 1. On the other hand, when the filtering device 2 does not need to be tested, the conductive switch 7 is in the open position state, which is safe to operate. And when the conductive switch 7 is in the open position state, it is easy to place the filtering device 2 on the machine base 1.

[0043] The positioning tooling 6 is movably arranged on the machine base 1, and a vibration motor 11 acting on the positioning tooling 6 is also provided on the machine base 1; during the test, the vibration motor 11 is electrically connected to the power supply module 4 and drives the filtering device 2 to vibrate through the positioning tooling 6 to detect whether foreign objects are accidentally placed in the delivery cavity of the filtering device 2 (taking a gas filtering device as an example for illustration. There is a delivery cavity for transporting gas in the gas filtering device. To prevent the outlet end of the delivery cavity from being blocked by foreign objects, it is required that there are no foreign objects in the delivery cavity).

[0044] During the filling process of the filtering device, foreign objects may accidentally fall into the interior of the conveying cavity of the filtering device. In order to further detect whether there are foreign objects in the conveying cavity, a vibration motor is set to make the filtering device vibrate. During the vibration process, the foreign objects that accidentally fall into the interior of the conveying cavity will most likely block the outlet end of the conveying cavity, resulting in a decrease in the reading of the flux monitor. Therefore, it is possible to determine whether there are foreign objects in the conveying cavity through the reading of the flux monitor, so as to screen out unqualified filtering devices, prevent unqualified filtering devices from flowing into the market, and avoid users purchasing unqualified products.

The adjustment module 12 includes a potentiometer connected to the power supply module 4 through a wire, and a rotating adjustment knob 13 is provided on the potentiometer.

[0047] The conductive switch 7 needs to be rotated to the closed position state to make the control detection circuit connected, which has the characteristic of safe operation and avoids the situation that the conductive switch 7 is not closed in place.

[0050] If there are foreign objects in the conveying cavity and the particle size of the foreign objects is small enough (it can enter the conveying pipe assembly), the foreign objects will be blown into the filter. The foreign objects enter the inner cavity of the filter through the filter pipe and finally uniformly fall on the falling-back area, preventing foreign objects from existing in the pipeline of the conveying pipe assembly during the detection process of the next filtering device, thereby avoiding affecting the detection result of the flux monitor and preventing the detection result from deviating.
