Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection technology, and in particular to a user-friendly particle detector. Background Technology
[0002] The particulate detector mainly consists of a sampler, a sensor, a computer-controlled detection and data processing system, and a printing system. It utilizes the sensor principle of the optical barrier method: the liquid being detected passes through a specially designed flow chamber, and the incident light beam perpendicular to the liquid flow direction is weakened by the particles in the liquid, causing a change in the sensor's output signal. This signal change is proportional to the cross-sectional area of the particle as it passes through the light beam. This proportional relationship reflects the particle size. Each particle passing through the light beam generates a voltage pulse signal; the number of pulses reflects the particle quantity. This detection method is suitable for detecting the size and quantity of insoluble particles in transparent liquids with various dispersion media. It is mainly used in the pharmaceutical and food industries for detecting the number and size of particles.
[0003] Currently, the stage of the particulate detector is a fixed size and height, and the height of the sample placement stage cannot be adjusted. The sample placement stage surface is smooth and there is no device to prevent the sample bottle from tipping over. During the detection process, the bottle often tipped over due to the contact between the sampling head and the bottle, causing pollution to the instrument and the environment, as well as waste of samples. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a user-friendly particle detector, comprising a detector body, a detection cavity provided on the right side of the detector body, and a lifting mechanism provided inside the detection cavity;
[0006] The lifting mechanism includes a telescopic assembly, a placement platform, and four slide rails. The four corners of the placement platform are slidably connected to the outer periphery of the slide rails. The side of the slide rail away from the placement platform is fixedly connected to the inner wall of the detection chamber. The middle of the left and right sides of the placement platform is connected to the telescopic assembly. The telescopic assembly is installed on the inner walls of the upper and lower sides of the detection chamber and connected to each other.
[0007] Preferably, the detector body has a glass window at the front, and the glass window is located at the front of the detection chamber.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figure 1-3 As shown, a user-friendly particle detector includes a detector body 1, a detection chamber 2 on the right side of the detector body 1, and a lifting mechanism 3 inside the detection chamber 2.
[0020] In this embodiment, the lifting mechanism 3 includes a lowering assembly 301, a placement platform 302, and four slide rails 303. The four corners of the placement platform 302 are slidably connected to the outer periphery of the slide rails 303. The side of the slide rails 303 away from the placement platform 302 is fixedly connected to the inner wall of the detection chamber 2. The middle of the left and right sides of the placement platform 302 is connected to the lowering assembly 301. The lowering assembly 301 is installed on the inner walls of the upper and lower sides of the detection chamber 2. A glass window is provided at the front of the detector body 1. The glass window is located at the front of the detection chamber 2. An anti-slip pad is installed at the bottom of the detector body 1. A pneumatic chuck 304 is installed in the middle of the placement platform 302. The output end of the pneumatic chuck 304 is wrapped with a rubber pad. The pneumatic chuck 304 is aligned with the probe.
[0021] Specifically, the slide rail 303 enables the extension and lowering assembly 301 to smoothly move the placement platform 302 up and down, thereby allowing the placement platform 302 to move the vessel up and down to accommodate vessels of different heights. At the same time, the pneumatic chuck 304 can clamp and fix the vessel, causing the vessel to move towards the center of the pneumatic chuck 304, thereby aligning the center of the vessel with the probe, preventing the probe from colliding with the vessel wall, and effectively protecting the probe.
[0022] In this embodiment, the extension / retraction assembly 301 includes two lead screws 3011 (left and right), two pulleys 3012 (left and right), a belt 3013, two gears 3014 (left and right), and a servo motor 3015. The upper and lower ends of the lead screws 3011 are rotatably connected to the left and right sides of the detection chamber 2. The middle part of the pulleys 3012 is fixedly connected to the lower end of the lead screws 3011. The left and right ends of the belt 3013 are internally meshed with the outer periphery of the pulleys 3012. The left gear 3014 is fixedly connected to the lower part of the left pulley 3012, and the middle part of the right gear 3014 is fixedly connected to the upper output end of the servo motor 3015. The two gears 3014 are connected in phase. The servo motor 3015 is installed on the bottom wall of the detection chamber 2. The extension and lowering assembly 301 also includes a helical gear 3016, a helical gear 3017, a shaft 3018, and a knob 3019. The middle of the helical gear 3016 is fixedly connected to the lower end of the right lead screw 3011, and the middle of the helical gear 3017 is fixedly connected to one end of the shaft 3018. The helical gear 3016 and the helical gear 3017 mesh with each other. The outer circumference of the shaft 3018 passes through and is rotatably connected to the side wall of the detection chamber 2. The end of the shaft 3018 away from the helical gear 3017 is fixedly connected to the knob 3019.
[0023] Specifically, the servo motor 3015 drives the left lead screw 3011 to rotate via two gears 3014. This rotation, in turn, drives the other lead screw 3011 to rotate synchronously via pulley 3012 and belt 3013. Because the slide rail 303 restricts the placement platform 302, the platform 302 can move the pneumatic chuck 304 up and down as the lead screw 3011 rotates. When the servo motor 3015 fails, turning the knob 3019 causes the second helical gear 3017 to rotate the first helical gear 3016, which in turn drives the two lead screws 3011 to rotate synchronously via pulley 3012 and belt 3013. Therefore, both manual and automatic adjustments are possible, making the system more convenient to use.
[0024] Working principle:
[0025] The slide rail 303 allows the extension and lowering assembly 301 to smoothly move the placement platform 302 up and down, thereby enabling the placement platform 302 to move the vessel up and down to accommodate vessels of different heights. At the same time, the pneumatic chuck 304 can clamp and fix the vessel, allowing the vessel to move towards the center of the pneumatic chuck 304, thus aligning the center of the vessel with the probe, preventing the probe from colliding with the vessel wall, and effectively protecting the probe.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
