Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling cone cleaning technology, and in particular to a cleaning device suitable for sampling cones. Background Technology
[0002] The sampling cone and retrieval cone of an inductively coupled plasma mass spectrometer are key components of the instrument's sample introduction system. They are responsible for extracting the ion flow from the high-temperature plasma and transmitting it to the mass spectrometer. During use, the cone orifice (especially the sampling cone orifice) is very easily blocked or deposited by the sample matrix, salts, particles, etc., which reduces the sensitivity of the equipment and affects the accuracy of the test results.
[0003] Existing cleaning methods typically involve manual cleaning, using fine needles, cotton swabs, abrasive paste, or specialized conical drills for manual unblocking and polishing. This method is time-consuming, labor-intensive, and inefficient, requiring highly skilled operators to avoid damaging the conical hole, leading to deformation, scratches, and enlargement of the hole diameter. Even minor changes in the size and shape of the conical hole can significantly affect the instrument's sensitivity, stability, and abundance sensitivity. Therefore, a cleaning device suitable for sampling cones is proposed for improvement. Utility Model Content

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:
[0014] 1. This utility model utilizes nylon bristles to penetrate deep into the cone hole for physical friction, while cleaning fluid is atomized from the liquid nozzle to cover and dissolve stains.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a cleaning device suitable for sampling cones, including a housing 1. A servo motor 2 is fixedly installed on the inner wall of the front side of the housing 1 by a pad 25. A gear 21 is fixedly sleeved on the output shaft of the servo motor 2. A gear ring 22 is meshed on the outer surface of the gear 21. A hollow rotating shaft 23 is fixedly sleeved inside the gear ring 22. The hollow rotating shaft 23 is rotatably connected to the front end of the housing 1. A rotating rod 3 is provided at one end of the hollow rotating shaft 23. The rotating rod 3 is hollow. A nylon brush bristle 31 is fixedly connected to one end of the rotating rod 3.
[0024] A liquid storage chamber 11 is provided on the inner wall of the rear side of the housing 1. A micro water pump 4 is fixedly installed on the inner wall of the liquid storage chamber 11. An infusion tube 41 is fixedly connected to the output end of the micro water pump 4. One end of the infusion tube 41 passes through the inner wall of the liquid storage chamber 11 and extends into the inside of the rotating rod 3. A liquid nozzle 42 is provided at the end of the infusion tube 41 that extends into the inside of the rotating rod 3.
[0025] A miniature air pump 5 is fixedly installed in the middle of the housing 1. An air supply pipe 51 is fixedly connected to the output end of the miniature air pump 5. One end of the air supply pipe 51 passes through the interior of the hollow rotating shaft 23 and extends into the interior of the rotating rod 3. An air nozzle 52 is provided at the end of the air supply pipe 51 that extends into the interior of the rotating rod 3.
[0026] During use, when it is necessary to clean the sampling cone, place the sampling cone flat on the table and start the servo motor 2. Its output shaft drives the gear ring 22 to rotate through the gear 21. The gear ring 22 drives the hollow rotating shaft 23 to rotate, which in turn drives the rotating rod 3 and nylon bristles 31 to rotate and physically clean the surface of the sampling cone. The rotating rod 3 and nylon bristles 31 can accurately extend into the cone hole and rotate and rub to remove deposits.
[0027] At the same time, the micro water pump 4 and the micro air pump 5 are started. The micro water pump 4 delivers the cleaning liquid into the infusion tube 41. When the cleaning liquid flows into the inside of the rotating rod 3 in the infusion tube 41, it is atomized and sprayed out from the liquid nozzle 42 to cover the nylon bristles 31 brushing area and dissolve the surface stains. The micro air pump 5 sprays compressed air from the air nozzle 52 through the air infusion tube 51 to purge the sampling cone, so that the cleaning liquid and compressed air work together to flush the sample cone.
[0028] This design utilizes nylon bristles 31 to penetrate deep into the cone orifice for physical friction. Cleaning fluid is atomized from the liquid nozzle 42 to cover and dissolve stains, while compressed air is blown away by the air nozzle 52 to remove residues. This multi-dimensional and rapid removal of deposits minimizes the risk of physical damage to the sampling cone, especially the cone orifice, significantly improves cleaning efficiency and speed, reduces operational difficulty and skill requirements, minimizes human error, reduces instrument performance fluctuations caused by cleaning variations, reduces accidental cone damage and replacement frequency, and saves on consumable costs.
[0029] Reference Figures 1-4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: the front side of the housing 1 is provided with a quick-release mechanism 6 for easy cleaning and maintenance; the hollow rotating shaft 23 has mounting grooves 24 on both sides of one end; the rotating rod 3 has mounting plates 62 fixedly connected to both sides of one end; and the mounting plates 62 are fitted into the inner wall of the mounting grooves 24.
[0030] The hollow rotating shaft 23 is symmetrically provided with a fixed seat 61 at one end. The bottom end of the fixed seat 61 contacts the top end of the mounting plate 62. The inner wall of the fixed seat 61 is provided with a sliding groove 63. A sliding ring 64 is slidably connected to the inner wall of the sliding groove 63. A locking rod 65 is fixedly sleeved inside the sliding ring 64. The bottom end of the locking rod 65 passes through the inner wall of the sliding groove 63 and is fitted into the top groove of the mounting plate 62.
[0031] The top of the lever 65 passes through the inner wall of the slide groove 63 and is fixedly connected to an arc-shaped pull plate 66. The inner side of the arc-shaped pull plate 66 is fitted into the surface of the hollow rotating shaft 23.
[0032] A spring 67 is fitted onto the surface of the lever 65, and the two ends of the spring 67 are connected to the top of the slip ring 64 and the inner wall of the slide groove 63, respectively.
[0033] During use, when it is necessary to disassemble the rotating rod 3, pull the arc-shaped pull plate 66 upward. The arc-shaped pull plate 66 drives the two side locking rods 65 to move upward simultaneously, so that the bottom end of the locking rod 65 leaves the groove at the top of the mounting plate 62, releasing the constraint on the mounting plate 62. At the same time, the locking rod 65 drives the slip ring 64 to slide upward in the slide groove 63 and compresses the spring 67, so that it stores elastic potential energy.
[0034] Next, pull the rotating rod 3 outward along the axial direction of the hollow rotating shaft 23, so that the mounting plate 62 slides out of the mounting groove 24, thereby completely separating the rotating rod 3 from the hollow rotating shaft 23 and achieving the purpose of disassembling the rotating rod 3;
[0035] This device, through the design of the quick-release mechanism 6, eliminates the need for tools. Simply pull the arc-shaped pull plate 66 manually to disassemble the rotating rod 3. The quick disassembly of the rotating rod 3 allows for the separate cleaning or replacement of easily damaged parts such as the nylon bristles 31 and the liquid nozzle 42, significantly shortening maintenance time and improving equipment efficiency.
[0036] Reference Figures 1-4 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: an injection tube 12 is fixedly sleeved on the inner wall of the liquid storage chamber 11, and a sealing bolt 13 is threaded to one end of the injection tube 12. A switch assembly 14 is provided on the upper part of the housing 1.
[0037] During use, the injection tube 12 provides a channel for adding cleaning fluid, which facilitates the injection of liquid into the storage chamber 11. The sealing bolt 13 is threaded to one end of the injection tube 12 and is tightened to achieve a seal, preventing the cleaning fluid from leaking or evaporating and ensuring the airtightness of the storage chamber 11. The switch assembly 14 can start and stop the servo motor 2, the micro water pump 4, and the micro air pump 5 independently to meet the needs of different cleaning stages.
[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
