Description

Technical Field

[0001] This utility model relates to the field of lighting testing equipment, specifically to a clarity tester. Background Technology

[0002] The clarity tester is suitable for detecting the clarity of various injections, large-volume infusions, and bottled pharmaceutical solutions. It involves illuminating the solution to obtain the concentration of suspended solids, thereby determining the solution's clarity. In specific operations, for colorless test solutions packaged in colorless transparent containers, the illuminance at the location of the observed test sample should be 1000–1500 LUX; for test samples packaged in transparent plastic containers, brown transparent containers, or colored test solutions, the illuminance should be 2000–3000 LUX; and for suspensions or emulsions, the illuminance should be increased to approximately 4000 LUX.

[0003] In related technologies, the illuminance range of clarity detectors is usually set to be adjustable between 1000-4000 LUX, which can meet the illuminance requirements for light inspection of conventional transparent containers, but cannot meet the visual inspection requirements for illuminance standards higher than 4000 LUX, such as the illuminance requirements for light inspection of colored containers; therefore, it has the problem of relatively simple function and poor flexibility in illuminance requirements. Utility Model Content

[0004] In view of this, the present invention provides a clarity detector to solve the problems of clarity detectors in related technologies being unable to meet visual inspection requirements with illuminance standards higher than 4000 LUX, having relatively simple functions, and lacking flexibility in illuminance requirements.

[0005] This utility model provides a clarity measuring instrument, comprising:

[0006] The housing has a recessed detection chamber.

[0007] The lighting assembly includes a first lighting unit and a second lighting unit, which are detachably disposed at a distance from each other in the top area of ​​the detection chamber. The first lighting unit is electrically connected to a first control switch, and the second lighting unit is electrically connected to a second control switch. The operating end of either control switch is mounted on the outer wall of the chamber. The range of the superimposed illuminance of the first lighting unit and the illuminance of the second lighting unit is set to 1000LUX-10000LUX.

[0008] Beneficial effects: The solution sample to be tested is placed in the detection chamber on the box. The opening and closing state of the first illumination unit is controlled by operating the first control switch, and the opening and closing state of the second illumination unit is controlled by the second control switch. By superimposing the illuminance of the first illumination unit and the illuminance of the second illumination unit, the measurement range of the illuminance of the clarity detector is expanded. The superimposed illuminance is set to 1000LUX-10000LUX, which can meet the specifications of different pharmacopoeias. This method can improve the adaptability of the instrument to the illumination range under different conditions, meet the testing needs of colorless and colored containers, and improve the practicality of the detection instrument in the visual inspection stage.

[0009] In one alternative implementation, the first control switch is configured as an adjustment knob, and the second control switch is configured as an opening / closing element.

[0010] Beneficial effects: The first control switch is set as an adjustment knob, which allows the user to actively adjust the illuminance of the first lighting unit to match the illuminance required in the visual inspection stage; the second control switch is set as an on / off switch, which enables the second lighting unit to have a constant illuminance; in the specific matching process, only the first control switch or the second control switch can be turned on, or the illuminance of both can be superimposed to flexibly match the required usage conditions.

[0011] In one optional embodiment, the illuminance of the first lighting unit is set to 1000 LUX-4000 LUX, and the illuminance of the second lighting unit is set to 6000 LUX; or,

[0012] The illuminance of the first lighting unit is set to 1000 LUX-4000 LUX, and the illuminance of the second lighting unit is set to 7000 LUX.

[0013] In one optional embodiment, the first control switch and the second control switch are disposed on the right side of the housing, with the first control switch disposed in the upper region of the right side of the housing and the second control switch disposed in the lower region of the right side of the housing.

[0014] Beneficial effects: The first control switch is located in the upper area of ​​the right side of the cabinet, and the second control switch is located in the lower area of ​​the right side of the cabinet. This arrangement of the first and second control switches on the right side of the cabinet facilitates user operation and adjustment. The first control switch is located in a high position, allowing the user to raise their hand to rotate and adjust the first lighting unit, while the second control switch is located in a low position, allowing the user to directly turn the second lighting unit on and off. This makes the operation convenient.

[0015] In one alternative embodiment, the detection chamber is provided with a black background panel and a white background panel, the white background panel being attached to the side of the black background panel facing the detection chamber.

[0018] In the actual structural design, the first magnetic suction component can be set as the magnetic wall or magnetic attachment wall of the detection chamber, and the second magnetic suction component can be set as a magnetic component.

[0019] In one optional embodiment, the clarity detector further includes a first power supply component and a second power supply component. Either power supply component is mounted on the housing and is isolated from the detection chamber. The first power supply component is used to provide power to the first lighting unit, and the second power supply component is used to provide power to the second lighting unit. The first lighting unit, the first control switch, and the first power supply component together constitute a first electrical branch, and the second lighting unit, the second control switch, and the second power supply component together constitute a second electrical branch.

[0020] Beneficial effects: The first power supply unit provides power to the first lighting unit, and the second power supply unit provides power to the second lighting unit.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0037] According to an embodiment of the present invention, a clarity detector is provided, including a housing 1 and an illumination assembly, such as... Figure 1 and Figure 2 As shown, a detection chamber is recessed in the housing 1; the lighting assembly includes a first lighting unit 201 and a second lighting unit 202, which are detachably and spaced apart from each other in the top area of ​​the detection chamber. The first lighting unit 201 is electrically connected to a first control switch 203, and the second lighting unit 202 is electrically connected to a second control switch 204. The operating end of either control switch is installed on the outer wall of the housing 1. The range of the superimposed illuminance of the first lighting unit 201 and the illuminance of the second lighting unit 202 is set to 1000LUX-10000LUX.

[0038] The clarity detector provided in this embodiment places the solution sample to be tested in the detection chamber on the housing 1. The first control switch 203 controls the opening and closing of the first illumination unit 201, and the second control switch 204 controls the opening and closing of the second illumination unit 202. By superimposing the illuminance of the first illumination unit 201 and the illuminance of the second illumination unit 202, the measurement range of the illuminance of the clarity detector is expanded. The superimposed illuminance is set to 1000LUX-10000LUX, which can meet the specifications of different pharmacopoeias. This method can improve the adaptability of the instrument to the illumination range under different conditions, meet the detection needs of colorless and colored containers, and improve the practicality of the detection instrument in the visual inspection stage.

[0039] In one alternative implementation, the first control switch 203 is configured as an adjustment knob, and the second control switch 204 is configured as an opening / closing element. The opening / closing element can be configured as a push-button switch.

[0040] In this scheme, the first control switch 203 is set as an adjustment knob, allowing the user to actively adjust the illuminance of the first lighting unit 201 to match the illuminance required during the visual inspection stage; the second control switch 204 is set as an on / off element, so that the second lighting unit 202 has a constant illuminance; in the specific matching process, only the first control switch 203 or the second control switch 204 can be turned on, or the illuminance of both can be superimposed to flexibly match the required usage conditions.

[0041] In one optional implementation, the illuminance of the first lighting unit 201 is set to 1000 LUX-4000 LUX, and the illuminance of the second lighting unit 202 is set to 6000 LUX.

[0042] In another optional embodiment, the illuminance of the first lighting unit 201 is set to 1000 LUX-4000 LUX, and the illuminance of the second lighting unit 202 is set to 7000 LUX.

[0043] In one specific implementation, such as Figure 1 As shown, the first control switch 203 and the second control switch 204 are located on the right side of the enclosure 1. The first control switch 203 is located in the upper area of ​​the right side of the enclosure 1, and the second control switch 204 is located in the lower area of ​​the right side of the enclosure 1. This arrangement, with the first control switch 203 in the upper area of ​​the right side of the enclosure 1 and the second control switch 204 in the lower area, allows for easy user operation and adjustment. The first control switch 203 is in a higher position, allowing the user to easily adjust the first lighting unit 201, while the second control switch 204 is in a lower position, allowing the user to directly turn the second lighting unit 202 on and off. The illuminance of the first lighting unit 201 is adjustable, while the illuminance of the second lighting unit 202 is a fixed value, making operation convenient.

[0044] In one alternative implementation, such as Figure 1 As shown, the detection chamber is equipped with a black background plate 101 and a white background plate 102, with the white background plate 102 attached to the side of the black background plate 101 facing the detection chamber. During operation, the solution sample can be detected using either the black background plate 101 or the white background plate 102.

[0045] In one alternative embodiment, the clarity meter further includes a mounting assembly for mounting and securing the second illumination unit 202; such as Figure 3As shown, the mounting assembly includes a first magnetic chuck 401 and a second magnetic chuck 402. The first magnetic chuck 401 is fixedly connected to the detection chamber, and the second magnetic chuck 402 is fixedly connected to the second illumination unit 202. One or more sets of the first magnetic chuck 401 and the second magnetic chuck 402 can be provided to fix the second illumination unit 202 to the detection chamber.

[0046] In this scheme, the second lighting unit 202 is detachably assembled into the detection chamber by installing the components. It is fixed to the detection chamber by the first magnetic 401 and the second magnetic 402. The first magnetic 401 and the second magnetic 402 are then directly connected to fix the second lighting unit 202 relative to the detection chamber.

[0047] In the actual structural design, the first magnetic suction component 401 can be set as the magnetic wall or magnetic attachment wall of the detection chamber, and the second magnetic suction component 402 can be set as a magnetic component.

[0048] In one alternative implementation, such as Figure 4 As shown, the clarity tester also includes a first power supply unit 205 and a second power supply unit 206. Either power supply unit is installed on the housing 1 and is isolated from the test chamber. The first power supply unit 205 is used to provide power to the first lighting unit 201, and the second power supply unit 206 is used to provide power to the second lighting unit 202. The first lighting unit 201, the first control switch 203 and the first power supply unit 205 together constitute a first electrical branch, and the second lighting unit 202, the second control switch 204 and the second power supply unit 206 together constitute a second electrical branch.

[0049] In this scheme, the first power supply unit 205 is used to provide power to the first lighting unit 201, and the second power supply unit 206 is used to provide power to the second lighting unit 202. The first lighting unit 201 and the second lighting unit 202 are each configured with an independent power supply, which reduces the interference between the first and second electrical branches and helps to improve the endurance stability of the instrument.

[0050] In one alternative implementation, such as Figure 4 As shown, the clarity tester also includes a main switch 103. The operating terminal of the main switch 103 is located on the outer wall of the housing 1. The first electrical branch and the second electrical branch are connected in parallel at the connection terminal of the main switch 103. The main switch 103 can be configured to control the first electrical branch and the second electrical branch. When the main switch 103 and the first control switch 203 are turned on, the first lighting unit 201 of the first electrical branch is in working mode. When the main switch 103 and the second control switch 204 are turned on, the second lighting unit 202 of the second electrical branch is in working mode.

[0051] In one alternative implementation, the clarity detector further includes auxiliary components, such as... Figure 5 As shown, the auxiliary components include a photodetector 301, a timing module 302, a start switch 303, and an indicator light 304. At least one photodetector 301 is provided, and its detection end is located within the detection chamber. The photodetector 301 and the timing module 302 are electrically connected. The indicator light 304 is also electrically connected to the timing module 302. The start switch 303 is electrically connected to both the photodetector 301 and the timing module 302 to activate and deactivate them. This scheme assists in the detection of visually inspected solution samples. The photodetector 301 detects and determines the position of the solution sample within the detection chamber. The timing module 302 automatically starts timing based on the position information. If the set time has not been reached, the indicator light 304 emits a color warning to assist the user's visual inspection.

[0052] During the actual operation, the solution sample can be visually inspected against both the black background plate 101 and the white background plate 102. Two photodetectors 301 can be configured: one photodetector 301 is positioned within the detection chamber containing the black background plate 101, and the other photodetector 301 is positioned within the detection chamber containing the white background plate 102. The solution sample can trigger an automatic timer, and an indicator light 304 will illuminate if the time requirement is not met.

[0053] The timing module 302 specifically includes a pulse generator, a counter, a controller, and a display screen. The controller is connected to the photoelectric detector 301, identifies the arrival information fed back by the photoelectric detector 301, and responds to the feedback by activating the pulse generator to produce a pulse signal. The counter counts the pulses, and the display screen shows the time. If the set time has not been reached, an indicator light 304 emits a color warning to remind the user that the set detection time has not been reached, which helps improve the reliability of the detection. The timing module 302 can be connected to the first power supply unit 205, which provides the power for the timing module 302 to operate.
