Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic cleaning, in particular to a cleaning water outlet structure and a high-performance sample needle cleaning device containing the same. Background Art

[0002] Ultrasonic cleaning utilizes the cavitation, acceleration, and straight-through flow of ultrasound in liquids to directly and indirectly disperse, emulsify, and peel off the dirt layer, achieving the cleaning purpose. Ultrasonic cleaning technology has been widely used in various cleaning fields.

[0003] Existing sample needle cleaning devices typically use a transducer plus cleaning tank model, with the transducer bonded to the bottom of the cleaning tank or screwed to the bottom of the cleaning tank using threads. This type of cleaning device usually requires the addition of adhesive between the transducer and the cleaning tank to ensure the coupling coefficient. This process often results in a chaotic impedance characteristic curve of the cleaning component (transducer + cleaning tank), and its consistency is less than ideal. The cleaning component will deviate each time it is started, resulting in inconsistent sound field intensity within the cleaning tank and uncertainty in the cleaning effect. Secondly, existing cleaning tanks are often large in size, and stains are easily left inside the cleaning tank, which can easily cause secondary contamination of the sample needle. The unsatisfactory impedance characteristics of the cleaning component are often manifested as excessive internal resistance and reactance confusion. Excessive internal resistance results in severe losses, which manifests as low electroacoustic efficiency. Reactance confusion makes it difficult for the power supply to lock its frequency, and it is prone to fluctuations during operation. The coupling coefficient between the transducer and the cleaning tank is greatly affected by the adhesive. The high-frequency vibration generated by the end face of the transducer will be transmitted to the cleaning tank through the adhesive layer. As the components are continuously used, the bonding force between the adhesive layer and the transducer and the cleaning tank will continue to decrease. This decrease will directly affect the performance of the cleaning component and thus its life. Summary of the Invention

[0016] Preferably, one end of the first rotating shaft is rotatably connected in the mixing bin, the other end of the first rotating shaft is inserted into the water inlet pipe, and the end of the first rotating shaft located in the water inlet pipe is fixedly connected to the impeller and the first bevel gear, the first bevel gear is meshed with the second bevel gear, the second bevel gear is located in the water inlet pipe, the second bevel gear is fixedly connected to the second rotating shaft, the second rotating shaft is rotatably connected to the water inlet pipe, and one end of the second rotating shaft passes through the water inlet pipe.

[0017] Preferably, one end of the second rotating shaft located outside the water inlet pipe is fixedly connected to a disc, a connecting shaft is fixedly connected to the disc, the disc is rotatably connected to the middle section of the connecting rod via the connecting shaft, one end of the connecting rod is rotatably connected to a rotating ring, the rotating ring is sleeved outside the water inlet pipe, and the rotating ring is slidably connected to the outer wall of the water inlet pipe, the rotating ring is rotatably connected to the slip ring plate, and the slip ring plate is slidably connected to the water inlet pipe;

[0021] Preferably, a stirring rod is fixedly connected to the mixing fixed plate.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] Water enters the outlet through the water inlet, and the tip of the ultrasonic transducer penetrates the outlet. This solves the problem of existing processes that glue the transducer to the bottom of the cleaning tank or use threads to lock the transducer to the bottom of the cleaning tank and add adhesive (glue) between the transducer and the cleaning tank to ensure the coupling coefficient, which leads to a chaotic impedance characteristic curve of the cleaning component and less than ideal consistency. It also solves the problem of deviations in the cleaning component each time it is started, resulting in inconsistent sound field intensity in the cleaning tank and uncertainty in the cleaning effect.

[0024] This solution solves the problem of the impedance characteristics of the transducer assembly by changing the structure of the conventional ultrasonic cleaning tank (no coupling is required between the transducer and the cleaning tank), ensuring the frequency locking stability of the ultrasonic power supply (the existing technology uses adhesives to ensure the coupling coefficient, and the impedance characteristics of the cleaning assembly are not ideal, often showing excessive internal resistance and reactance confusion. Excessive internal resistance leads to serious losses, which manifests as low electroacoustic efficiency. Reactance confusion makes it difficult for the power supply to lock its frequency, and it is prone to fluctuations during operation. The coupling coefficient between the transducer and the cleaning tank is greatly affected by the adhesive).

[0025] This solution changes the structure of conventional ultrasonic cleaning tanks (no coupling is required between the transducer and the cleaning tank, and the existing adhesive that ensures the coupling coefficient between the transducer and the cleaning tank is eliminated). This prevents the high-frequency vibration generated by the ultrasonic transducer from being transmitted to the cleaning tank through the adhesive layer. This avoids the problem that the bonding force between the adhesive layer, the transducer, and the cleaning tank will continue to decrease with the continuous use of the ultrasonic transducer, thereby affecting the performance of the cleaning component and thus its lifespan.

[0026] The ultrasonic transducer acts on the water flow in the water outlet, which disperses, emulsifies, and peels off the dirt layer on the sample needle. The tapered and notched design of the front end of the water outlet effectively focuses the cleaning fluid to ensure high cleaning efficiency. The notch design ensures that the used lotion flows effectively out to the main body shell and prevents the liquid from contacting the sample needle after cleaning. This solves the problem that existing cleaning pools are often large in size and residual stains in the cleaning pool are very likely to cause secondary contamination to the sample needle.

[0027] In the existing cleaning device, the cleaning liquid is directly mixed in the cleaning tank. This solution changes the cleaning method of the cleaning tank and uses flowing water to clean the sample needle. Before cleaning, the water and cleaning liquid are mixed through an adaptive mixing device, and the amount of cleaning liquid mixed is changed according to the strength of the water flow, which ensures the cleaning effect and avoids the waste of cleaning liquid.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Example 1

[0035] See also Figure 1-2 The present invention provides a technical solution: a cleaning water outlet structure, comprising a main body shell 1, a water outlet nozzle 2 is provided on the inner side of the upper part of the main body shell 1, a fixed groove 4 is provided below the main body shell 1, a water inlet 3 is provided on the side wall of the fixed groove 4, an ultrasonic transducer 5 is provided below the fixed groove 4, the water outlet nozzle 2 is connected to the water inlet 3, the output end of the ultrasonic transducer 5 is located in the pipeline between the water outlet nozzle 2 and the water inlet 3, a drain outlet 6 is provided on one side of the fixed groove 4, the drain outlet 6 is fixedly connected to the main body shell 1, and the drain outlet 6 is connected to the inside of the main body shell 1.

[0036] Preferably, a limiting ring 8 is fixedly connected to the ultrasonic transducer 5, the limiting ring 8 is located in the fixing groove 4, and the limiting ring 8 abuts against the lower surface of the main body shell 1;

[0037] A waterproof silica gel 9 is connected to the lower side of the limiting ring 8, and the waterproof silica gel 9 is sleeved on the ultrasonic transducer 5;

[0038] A spiral ring 10 is sleeved on the ultrasonic transducer 5 , and the spiral ring 10 is threadedly connected to the fixing groove 4 . The limiting ring 8 and the waterproof silica gel 9 are located between the spiral ring 10 and the lower surface of the main body shell 1 .

[0039] Preferably, the water outlet 2 is connected to the main body shell 1 through a thread;

[0040] The drain outlet 6 is provided with a fastening step 7;

[0041] The main body shell 1 is fixedly connected to a mounting flange 11;

[0042] The water outlet nozzle 2 is provided with a notch 12 .

[0043] The working principle and beneficial effects of the above scheme:

[0044] Water enters the water outlet 2 through the water inlet 3, and the tip of the ultrasonic transducer 5 extends through the water outlet 2. This solves the problem of the existing process of gluing the transducer to the bottom of the cleaning tank or locking the transducer to the bottom of the cleaning tank with threads and adding an adhesive (glue) between the transducer and the cleaning tank to ensure the coupling coefficient, which leads to a chaotic impedance characteristic curve and less than ideal consistency of the cleaning component. It also solves the problem of deviation of the cleaning component each time it is started, resulting in inconsistent sound field intensity in the cleaning tank and uncertainty in the cleaning effect.

[0045] This solution solves the problem of the impedance characteristics of the transducer assembly by changing the structure of the conventional ultrasonic cleaning tank (no coupling is required between the transducer and the cleaning tank), and ensures the frequency locking stability of the ultrasonic power supply (the prior art uses a process of adding adhesives to ensure the coupling coefficient, and the impedance characteristics of the cleaning assembly are not ideal, often showing excessive internal resistance and reactance confusion. If the internal resistance is too high, the loss will be serious, which is manifested as low electroacoustic efficiency. Reactance confusion makes it difficult for the power supply to lock its frequency, and it is easy to fluctuate during operation. The coupling coefficient between the transducer and the cleaning tank is greatly affected by the adhesive).

[0046] This solution changes the structure of the conventional ultrasonic cleaning tank (there is no need for coupling between the transducer and the cleaning tank, and the existing adhesive that ensures the coupling coefficient between the transducer and the cleaning tank is eliminated), so that the high-frequency vibration generated by the ultrasonic transducer 5 will not be transmitted to the cleaning tank through the adhesive layer, avoiding the problem that the bonding force between the adhesive layer and the transducer and the cleaning tank will continue to decrease with the continuous use of the ultrasonic transducer 5, affecting the performance of the cleaning component and thus affecting its life.

[0047] The ultrasonic transducer 5 acts on the water flow in the water outlet 2, and the water flow through the water outlet 2 disperses, emulsifies and peels off the dirt layer on the sample needle. The tapered design of the front end surface of the water outlet 2 and the notch 12 design can effectively focus the cleaning liquid through the design of the tapered structure to ensure high cleaning efficiency. The notch 12 is designed to ensure that the lotion after use flows effectively out to the main body shell 1 and avoid contact between the liquid and the sample needle after cleaning, which solves the problem that the existing cleaning pool is often large in size and the stains remaining in the cleaning pool are very likely to cause secondary contamination to the sample needle.

[0049] See also Figure 1-4 Based on Example 1, a high-performance sample needle cleaning device includes a cleaning water outlet structure and an adaptive mixing device 13. The adaptive mixing device 13 is arranged between the water inlet 3 and the water source, and the adaptive mixing device 13 is used to mix water and cleaning liquid.

[0052] Preferably, one end of the second rotating shaft 1308 located outside the water inlet pipe 1303 is fixedly connected to a disc 1309, and a connecting shaft 1310 is fixedly connected to the disc 1309. The disc 1309 is rotatably connected to the middle section of a connecting rod 1311 via the connecting shaft 1310. One end of the connecting rod 1311 is rotatably connected to a rotating ring 1312. The rotating ring 1312 is sleeved on the outside of the water inlet pipe 1303 and is slidably connected to the outer wall of the water inlet pipe 1303. The rotating ring 1312 is rotatably connected to a slip ring plate 1321, and the slip ring plate 1321 is slidably connected to the water inlet pipe 1303.

[0053] A sealing rod 1313 is fixedly connected to the outside of the slip ring plate 1321 . The sealing rod 1313 is inserted into a sealing groove 1314 . The sealing groove 1314 is provided on a partition plate 1315 between the mixing bin 1301 and the cleaning liquid bin 1302 . The sealing groove 1314 passes through the partition plate 1315 .

[0054] Preferably, the other end of the connecting rod 1311 is rotatably connected to one end of a sliding rod 1316, and the sliding rod 1316 is slidably connected to a sealing sleeve 1317. The sealing sleeve 1317 is arranged on the dividing plate 1315 between the mixing chamber 1301 and the cleaning liquid chamber 1302. The sealing sleeve 1317 passes through the dividing plate 1315, and the other end of the sliding rod 1316 is located in the mixing chamber 1301.

[0055] Preferably, one end of the sliding rod 1316 located in the mixing chamber 1301 is rotatably connected to the slider 1318, the slider 1318 is slidably connected to the mixing fixed plate 1319, and the mixing fixed plate 1319 is slidably connected to the first rotating shaft 1305, and the mixing fixed plate 1319 and the first rotating shaft 1305 are connected by a key.

[0056] Preferably, a stirring rod 1320 is fixedly connected to the mixing fixed plate 1319 .

[0057] The working principle and beneficial effects of the above scheme:

[0058] In existing cleaning devices, the cleaning liquid is directly mixed in the cleaning tank. This solution changes the cleaning method of the cleaning tank and uses flowing water to clean the sample needle. Before cleaning, the water and cleaning liquid are mixed by the adaptive mixing device 13. The amount of cleaning liquid mixed varies with the strength of the water flow, ensuring the cleaning effect and avoiding the waste of cleaning liquid.

[0059] Through the impeller 1304 provided in the water inlet pipe 1303, when water flows through the water inlet pipe 1303, the impeller 1304 rotates under the action of the water flow, driving the first bevel gear 1306 to rotate, and the second bevel gear 1307 engages to drive the disc 1309 to rotate. Two sets of crank slider structures are formed between the disc 1309, the connecting shaft 1310, the connecting rod 1311, the slide bar 1316, and the rotating ring 1312. The rotation of the disc 1309 drives the slide bar 1316 and the rotating ring 1312 to slide. The sealing rod 1313 is then driven by the slip ring plate 1321 to periodically move within the sealing groove 1314, thereby periodically conducting the mixing chamber 1301 and the cleaning liquid chamber 1302. The conduction frequency between the mixing chamber 1301 and the cleaning liquid chamber 1302 changes with the speed of the impeller 1304 (that is, the faster the water flow in the water inlet pipe 1303 and the faster the speed of the impeller 1304, the higher the conduction frequency between the mixing chamber 1301 and the cleaning liquid chamber 1302, and the more cleaning liquid in the cleaning liquid chamber 1302 enters the mixing chamber 1301).

[0060] The sliding of the slide bar 1316 causes the mixing fixed plate 1319 to move periodically in the mixing chamber 1301. The mixing fixed plate 1319 is keyed to the first rotating shaft 1305. The first rotating shaft 1305 drives the mixing fixed plate 1319 to rotate under the action of the impeller 1304, so that the stirring rod 1320 fixed to the mixing fixed plate 1319 rotates, mixing the water and cleaning liquid in the mixing chamber 1301. Since the movement of the mixing fixed plate 1319 is a mixed movement of rotation and translation, the mixing efficiency of the water and cleaning liquid in the mixing chamber 1301 is further increased, and the mixing uniformity of the water and cleaning liquid in the mixing chamber 1301 is increased.

[0061] Among them, the sliding connection between the slider 1318 and the hybrid fixed plate 1319 ensures the relative independence of the movements of the two, and ensures the realization of the hybrid movement of rotation and translation of the hybrid fixed plate 1319.

[0062] Example 3

[0063] On the basis of the above embodiments 1-2, a cleaning effect detection device is further included, and the cleaning effect detection device includes:

[0064] A flow rate sensor is provided on the water outlet 2 and is used to detect the flow rate of water at the water outlet 2;

[0065] A pressure sensor is provided on the water outlet 2 and is used to detect the water pressure at the water outlet 2;

[0066] Timer, used to record the duration of a single cleaning;

[0067] An alarm is provided on the main body shell 1;

[0068] A controller, wherein the controller is electrically connected to the flow rate sensor, the pressure sensor, the timer, and the alarm, and the controller controls the alarm based on the flow rate sensor, the pressure sensor, and the timer, including:

[0069] Step 1: The controller obtains a cleaning effect index based on the flow rate sensor, pressure sensor, timer, and formula:

[0070]

[0071] Wherein, A is the cleaning effect index, V is the water flow rate at the water outlet 2 detected by the flow rate sensor, R is the diameter inside the water outlet 2, P is the water pressure at the water outlet 2 detected by the pressure sensor, t is the single cleaning time recorded by the timer, W is the rated power of the ultrasonic transducer 5, ln is the logarithmic function with the natural constant as the base, and π is the pi;

[0072] Step 2: When the cleaning effect index is lower than a preset range, the controller controls the alarm to send out an alarm signal.

[0073] The working principle and beneficial effects of the above technical solution are as follows: a flow rate sensor is set on the water outlet 2 to detect the flow rate of water at the water outlet 2, a pressure sensor is set on the water outlet 2 to detect the pressure of water at the water outlet 2, and a timer is set to record the duration of a single cleaning. Then, the cleaning effect index can be calculated based on the flow rate of water at the water outlet 2 detected by the flow rate sensor, the pressure of water at the water outlet 2 detected by the pressure sensor, the duration of a single cleaning recorded by the timer, and the formula. When the cleaning effect index is lower than the preset range, the controller controls the alarm to send an alarm signal to remind the operator that the current cleaning effect may not meet the cleaning requirements of the sample needle, thereby enabling the operator to change the device configuration to meet the cleaning requirements of the sample needle. By setting this device, the intelligence of the equipment is improved.
