Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, specifically to a quick fixing device for ultrasonic cleaning atomizers. Background Technology

[0002] Liquid chromatography-mass spectrometry (LC-MS) is an analytical instrument that combines liquid chromatography with mass spectrometry. It integrates the high separation efficiency of LC with the high sensitivity and selectivity of mass spectrometry, making it a core tool in modern analytical chemistry. It is widely used in universities, research institutions, and enterprises. Maintaining the cleanliness of the instrument requires regular cleaning of the nebulizer. However, if non-professional engineers do not perform the cleaning, the nebulizer may come into contact with the inner wall of the cleaning container during ultrasonic cleaning, increasing the risk of damage to the nebulizer needle.

[0003] In existing technologies, the pipette tip is typically attached to the front end of the nebulizer's spray needle, and then the nebulizer is placed in a cleaning container for cleaning. However, when cleaning using the above method, long-term accumulated sample residues, salt crystals, or contaminants are not easily discharged from the spray needle, which can easily cause blockage of the spray needle and adhere to the inner wall of the nebulizer's nebulization chamber. This can lead to reduced ionization efficiency, signal drift, or increased background noise, affecting ion transmission efficiency and consequently causing unstable mass spectrometry response or decreased sensitivity. Utility Model Content

[0004] The purpose of this invention is to provide a quick fixing device for ultrasonic cleaning atomizers to overcome the problems existing in the prior art. This invention can solve the technical problem that the spray needle is easily damaged when cleaning the atomizer in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a quick fixing device for ultrasonic cleaning atomizers, comprising:

[0007] The clamping mechanism includes two parallel support rods, a connecting ring between the two support rods, and telescopic rods at both ends of each support rod. The two telescopic rods at the same end are connected by a baffle.

[0008] A protective tube is detachably mounted on the connecting ring. The protective tube is used to protect the atomizer. Two fixing nails are provided on the upper end face of the protective tube. The two fixing nails are used to position the atomizer.

[0009] Furthermore, the atomizer has an atomizing ring and a spray needle, the spray needle being disposed on the lower end face of the atomizing ring and located inside the protective tube;

[0010] Furthermore, the atomizing ring has a positioning hole that mates with the fixing pin. When the atomizer is placed on the protective tube, the fixing pin passes through the positioning hole of the atomizing ring.

[0011] Furthermore, the protective tube is threadedly connected to the connecting ring;

[0012] Furthermore, the upper end of the protective tube is provided with an external thread, and the circumferential surface inside the connecting ring is provided with an internal thread that is threadedly connected to the external thread. The protective tube and the connecting ring are connected by the external thread and the internal thread.

[0013] Furthermore, a connecting groove is formed through the inner side of the support rod along the height direction, and an adjusting rod that is slidably connected is provided in the connecting groove. The adjusting rod is fixedly installed on the outer peripheral wall of the connecting ring.

[0014] Furthermore, a threaded hole is provided through the outer side of the support rod, and a butterfly screw is provided in the threaded hole;

[0015] Furthermore, the screw-in end of the butterfly screw is detachably connected to the adjusting rod;

[0016] Furthermore, the support rod has mating holes at both ends along its length, the telescopic rod is disposed in the mating holes, and the extended end of the telescopic rod is connected to the baffle.

[0017] Furthermore, a spring is provided between the end of the support rod and the baffle, and the spring is fitted onto the extended end of the telescopic rod.

[0018] The above technical solution has the following advantages or beneficial effects:

[0019] This invention provides a rapid fixing device for ultrasonic cleaning nebulizers. To ensure the normal operation of the nebulizer and improve the stability of the mass spectrometry response, a protective tube is installed to provide all-round protection and cleaning for the nebulizer. During cleaning, sample residue inside the nebulizer can be effectively prevented from causing blockage. The vertical fixing of the protective tube is achieved by a clamping mechanism, which keeps a certain distance between the lower end of the protective tube and the bottom of the cleaning tank, i.e., the lower end of the protective tube does not contact the bottom of the cleaning tank, preventing the cleaning effect from being affected or the protective tube from being damaged due to contact with impurities at the bottom. At the same time, the clamping mechanism facilitates the disassembly and replacement of the protective tube. When the protective tube is damaged or becomes contaminated with stains that are difficult to clean due to long-term use, it can be quickly replaced, ensuring effective protection and cleaning of the nebulizer, preventing sample residue inside the nebulizer from causing blockage, and thus ensuring the stability of the liquid chromatography-mass spectrometry response.

[0020] Furthermore, in the quick-fixing device, the spray needle is positioned on the lower end face of the atomizing ring and placed inside the protective tube. On the one hand, the protective tube provides reliable physical protection for the spray needle, effectively preventing it from being damaged by external forces such as collisions and scratches during installation, use, and transportation, thus extending the service life of the spray needle and reducing replacement costs. On the other hand, the above structural layout places the spray needle in a relatively stable environment, reducing interference from external factors on its spray effect, ensuring the uniformity and stability of the spray, thereby improving the overall performance and working efficiency of the ultrasonic cleaning atomizer, and enhancing the reliability and practicality of the product.

[0021] Furthermore, the fixing pins engage with the positioning holes on the atomizing ring, enabling precise positioning during atomizer installation and quickly guiding the atomizer to the correct position, significantly reducing installation time and improving assembly efficiency. When the atomizer is placed on the protective tube, the fixing pins penetrate the positioning holes, effectively preventing the atomizer from shaking or shifting during use, ensuring its stability and guaranteeing the stability and reliability of the ultrasonic cleaning atomizer during operation.

[0022] Furthermore, the use of threaded connections makes installation and disassembly extremely convenient. Assembly or separation can be completed quickly simply by rotating the protective tube or connecting ring, greatly saving operation time and improving work efficiency. This is especially advantageous when frequent maintenance or replacement of parts is required. Moreover, the threaded connection has good self-locking properties, ensuring that the protective tube and connecting ring are tightly connected, effectively preventing loosening or falling off during operation, and ensuring the stability and reliability of the overall structure of the device.

[0023] Furthermore, a connecting groove and a sliding adjustment rod are provided on the inner side of the support rod, which can flexibly adjust the height of the connecting ring. In practical applications, the position of the connecting ring can be precisely adjusted according to the different specifications of ultrasonic cleaning atomizers or specific usage scenarios, thereby changing the height of related components such as the protective tube, which greatly enhances the versatility and adaptability of the device. The sliding connection method is simple to operate and the adjustment process is smooth. No complicated tools and cumbersome steps are required, and the height setting can be completed quickly, improving installation efficiency.

[0024] Furthermore, mating holes and telescopic rods are provided at both ends of the support rod, enabling the device to have flexible telescopic adjustment functions. In actual use, the extension length of the telescopic rod can be easily adjusted according to the size of the ultrasonic cleaning atomizer or the size of the installation space, allowing the baffle to be accurately positioned in the appropriate position, greatly enhancing the versatility and adaptability of the device. At the same time, the stable and reliable fit between the telescopic rod and the mating holes can effectively ensure the structural strength of the device during operation, providing stable support for the atomizer, improving the practicality and stability of the entire quick-fixing device, and meeting diverse usage needs.

[0025] Furthermore, a spring fitted onto the extended end of the telescopic rod is installed between the end of the support rod and the baffle, forming an elastic buffer system. When the ultrasonic cleaning atomizer is subjected to external impact during placement or operation, the spring can effectively absorb and disperse the impact force through its own elastic deformation, preventing hard collisions from damaging the atomizer and fixing device, greatly enhancing the device's impact resistance and extending its service life. At the same time, the elasticity of the spring can also ensure that the baffle always maintains appropriate pressure on the atomizer, ensuring its stable fixation and preventing loosening and displacement.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] See Figures 1-4 This utility model provides a quick fixing device for ultrasonic cleaning atomizers, including a clamping mechanism 2 and a protective tube 4. The clamping mechanism 2 includes two parallel support rods 21, with a connecting ring 22 between the two support rods 21. Each support rod 21 has a telescopic rod 26 at both ends, and the two telescopic rods 26 at the same end are connected by a baffle 28. The protective tube 4 is detachably mounted on the connecting ring 22 and is used to protect the atomizer 1. The upper end face of the protective tube 4 is provided with two fixing nails 23, which are used to position the atomizer 1.

[0038] It should be noted that when the spray needle 12 of the atomizer 1 is located inside the protective tube 4, the spray needle 12 does not contact the inner wall of the protective tube 4, and the protective tube 4 is filled with a cleaning medium, such as methanol, a mixture of methanol and water, or pure water. The cleaning medium in the protective tube 4 can be replaced according to the cleaning requirements of different atomizers 1. In addition, the protective tube 4 has a small structure, which saves cleaning medium. The cleaning tank 3 is filled with water. Water is used as the cleaning medium of the ultrasonic cleaner, which can ensure efficient cleaning while protecting the equipment safety. The atomizer 1 should be cleaned at least once a week to remove organic matter or inorganic salts adsorbed on the atomizer 1.

[0039] In the above scheme, the protective tube 4 is used to protect and clean the nebulizer 1, preventing sample residue in the nebulizer 1 from clogging it during the cleaning process. The clamping mechanism 2 vertically fixes the protective tube 4 so that the lower end of the protective tube 4 does not contact the bottom of the cleaning tank 3. The clamping mechanism 2 can also be easily disassembled and replaced, preventing sample residue in the nebulizer 1 from clogging it, thereby improving the stability of the liquid chromatography-mass spectrometry (LC-MS) response.

[0040] See some possible implementations. Figure 3 and Figure 4 The atomizer 1 has an atomizing ring and a spray needle 12. The spray needle 12 is located on the lower end face of the atomizing ring. The atomizing ring has a positioning hole 11 that cooperates with the fixing nail 23. When the atomizer 1 is placed on the protective tube 4, the fixing nail 23 passes through the positioning hole 11 of the atomizing ring, and the spray needle 12 is located inside the protective tube 4.

[0041] In the above scheme, when cleaning the atomizer 1, the atomizer 1 is vertically placed into the protective tube 4, so that the fixing nail 23 on the upper end of the protective tube 4 is inserted into the positioning hole 11 to fix the atomizer 1.

[0042] See some possible implementations. Figure 4 The protective tube 4 is threadedly connected to the connecting ring 22. The upper end of the protective tube 4 is provided with an external thread, and the inner circumferential surface of the connecting ring 22 is provided with an internal thread that is threadedly connected to the external thread. The protective tube 4 and the connecting ring 22 are connected by the external thread and the internal thread.

[0043] In the above scheme, the protective tube 4 generally needs to be replaced after 1-2 uses. By setting an external thread at the upper end of the protective tube 4, it is easy to detachably install the protective tube 4 on the connecting ring 22, which facilitates replacement and disassembly, and also facilitates the replacement of the cleaning medium inside.

[0044] See some possible implementations. Figure 4 A connecting groove is provided through the inner side of the support rod 21 along its height direction. An adjusting rod 24 is provided in the connecting groove and is fixedly installed on the outer peripheral wall of the connecting ring 22. A threaded hole is provided through the outer side of the support rod 21 and a butterfly screw 25 is provided in the threaded hole. The screw-in end of the butterfly screw 25 is detachably connected to the adjusting rod 24.

[0045] In the above scheme, in order to adapt to ultrasonic cleaners of different depths, when the distance between the bottom of the protective tube 4 and the bottom of the cleaning tank 3 is too large or too small, loosen the butterfly ear screw 25, press down the connecting ring 22 or pull up the connecting ring 22 so that the adjusting rod 24 slides in the connecting groove, thereby adjusting the height of the connecting ring 22, and thus adjusting the distance between the protective tube 4 and the bottom of the cleaning tank 3. After the adjustment is completed, tighten the butterfly ear screw 25 to re-fix the adjusting rod 24.

[0046] See some possible implementations. Figure 1 and Figure 4 The support rod 21 has mating holes at both ends along its length. The telescopic rod 26 is installed in the mating holes and the extended end of the telescopic rod 26 is connected to the baffle 28. A spring 27 is installed between the end of the support rod 21 and the baffle 28 and is fitted onto the extended end of the telescopic rod 26.

[0047] In the above scheme, when the clamping mechanism 2 is installed as a whole, the baffle 28 is pulled to increase the distance between the two baffles 28, and at the same time the elastic potential energy of the spring 27 increases. Then the two baffles 28 are respectively hung on both sides of the length direction of the cleaning tank 3. The spring 27 is reset, which drives the two baffles 28 to move closer together and clamp both sides of the length direction of the cleaning tank 3. At this time, the extended end of the telescopic rod 26 overlaps the edge of the cleaning tank 3.

[0048] This invention uses a protective tube 4 to protect and clean the nebulizer 1, preventing sample residue from clogging the nebulizer 1 during cleaning. The clamping mechanism 2 vertically fixes the protective tube 4, ensuring that its lower end does not contact the bottom of the cleaning tank 3. Furthermore, the clamping mechanism 2 allows for easy disassembly and replacement of the protective tube 4, further preventing sample residue from clogging the nebulizer 1 and improving the stability of the liquid chromatography-mass spectrometry (LC-MS) response.
