Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing equipment, in particular to an ultrasonic cleaning device for a glue dispensing needle. Background Art

[0002] The structure of the dispensing needle used in the dispensing equipment is similar to the needle on the conventional syringe. After being used for a period of time, a layer of glue will adhere to its inner wall, end and outer wall, which is not easy to scrape off when it dries. Therefore, it needs to be cleaned regularly after a certain period of use so that it can be reused to reduce economic costs. Conventionally, a device with a rotating brush is used to wipe and clean its surface, but if there is still dried glue inside and the inside is blocked, it is not easy to remove, so it needs to be replaced directly. In this way, the use cost of the dispensing needle cannot be effectively reduced.

[0003] In this regard, the inventor of this patent combined his work experience, conducted in-depth thinking on the problems encountered in the work, read a large amount of scientific research materials and literature, and through retrieval and novelty search, gradually conceived and designed this application to solve the relevant technical problems. Utility Model Content

[0013] According to an embodiment of the utility model, the upper portion of the inner wall of the cleaning chamber is flush with or slightly lower than the liquid inlet and is provided with a liquid level detection port, and the liquid level detection port is externally connected to a liquid level detection sensor connected to the main control device;

[0014] When the liquid level detection sensor detects that the liquid level in the cleaning chamber reaches the liquid level detection port, a signal can be transmitted to the main control device, so that the main control device can control the air pump to stop supplying air to the liquid storage barrel.

[0015] According to an embodiment of the utility model, it also includes a sealing cover plate for covering the upper opening of the cleaning chamber and a driving device connected to the main control device for controlling the movement of the sealing cover plate between the first position and the second position;

[0016] The connecting end of the sealing cover plate is fixed on the driving device; when the driving device drives the sealing cover plate to move to the first position, the sealing cover plate covers the upper opening of the cleaning chamber; when the driving device drives the sealing cover plate to move to the second position, the sealing cover plate opens the upper opening of the cleaning chamber.

[0017] According to an embodiment of the utility model, the driving device is a screw-driven linear module or a cylinder-driven linear module, and the driving device is fixed on the fixed seat, and a slider that can slide between the first position and the second position is provided on the fixed seat;

[0018] The sealing cover plate connecting end is fixed on the sliding block.

[0019] According to one embodiment of the utility model, it also includes a conical pressure member for driving the sealing cover plate to press the upper opening of the cleaning chamber;

[0020] The slider comprises an upper slider, a lower slider and an elastic member connected between the upper slider and the lower slider; the sealing cover plate connecting end is fixedly mounted on the upper slider; the upper slider has a pressure groove opened in the up-down direction facing the outer wall of the ultrasonic oscillation cleaner; the conical pressure member is transversely fixedly mounted on the outer wall of the ultrasonic oscillation cleaner, and its tip is facing the lower inner part of the pressure groove;

[0021] Initially, the sealing cover is located at a level slightly higher than the upper opening of the cleaning chamber. When the driving device drives the sealing cover to move to the first position, the pressure groove moves toward the conical pressure member, and the conical pressure member presses the pressure groove downward to drive the upper slider to drive the sealing cover to descend a preset stroke to press the upper opening of the cleaning chamber.

[0022] According to an embodiment of the utility model, the elastic member includes two guide rods and two compression springs;

[0024] The beneficial effects of the utility model are:

[0025] First, the ultrasonic cleaning device for dispensing needles provided in the present application adopts the principle of ultrasonic oscillation during its specific implementation to achieve all-round cleaning of the placed dispensing needles. Due to the advantages of ultrasonic oscillation itself, it uses the high-frequency sound waves of ultrasound to generate oscillations, so that the glue adhered to the inner wall, end and outer wall of the placed dispensing needle can be completely shaken off, so that it can be thoroughly cleaned in all directions to facilitate its reuse, which can greatly reduce the economic cost during use.

[0026] Secondly, since the present application is also provided with the blow dryer, after the placed dispensing needle is cleaned, it can be inserted into the needle insertion slot, and hot air can be blown into the needle insertion slot from the air inlet pipe. The hot air is discharged from top to bottom through the exhaust pipe, so that the outer and inner surfaces of the dispensing needle inserted into the needle insertion slot can be dried better, so that there is no water stain on it during subsequent use, which can better avoid wetting the circuit board and other products to be dispensed due to dripping of water stains, so that the present application has good reliability.

[0027] Thirdly, the present application comes with the liquid storage barrel for storing cleaning liquid, so that the cleaning liquid stored therein can be transported to the cleaning chamber through the liquid inlet pipe for use when needed. When the retractable sealing cover is opened, the required amount of cleaning liquid can be added to the liquid storage barrel regularly or irregularly, so that the present application can be used uninterruptedly.

[0028] Fourthly, the present application is provided with the liquid level detection sensor for monitoring the liquid level in the cleaning chamber and controlling its operation. When the used cleaning liquid in the cleaning chamber is drained and the cleaning liquid is loaded into the cleaning chamber, the cleaning liquid level can be monitored during the loading process so that the operator does not need to wait all the time. When the liquid level in the cleaning chamber reaches the liquid level detection port, the signal can be transmitted to the main control device. At this time, the main control device will control the air pump to stop supplying air to the liquid storage barrel to stop infusing cleaning liquid into the cleaning chamber. In this way, the present application is convenient and worry-free to use.

[0029] Fifth, by providing the conical pressure member, through the extrusion and pressing principle, the sealing cover plate can be driven to move a preset stroke while descending a preset stroke during the process of moving to the first position, so as to finally be driven to press the upper opening of the cleaning chamber. In this way, when the ultrasonic oscillation cleaner is working, the cleaning liquid loaded in the cleaning chamber is indeed not easy to overflow through its upper opening.

[0030] Sixth point, since the conical pressure member is transversely fixed on the outer wall of the ultrasonic oscillation cleaner, and its tip is facing the lower inner part of the pressure groove, when the driving device drives the sealing cover plate to move to the first position, the pressure groove moves toward the conical pressure member, and the conical pressure member squeezes the pressure groove downward to drive the upper slider to drive the sealing cover plate to descend a preset stroke to press the upper opening of the cleaning chamber. In this process, the conical pressure member can also play a certain role in isolating and protecting the ultrasonic oscillation cleaner. On the basis of its own elastic resistance, when the upper slider moves to the first position, it will not hit the ultrasonic oscillation cleaner hard due to the isolation protection and the elastic resistance applied by the conical pressure member, so that the ultrasonic oscillation cleaner has a long service life.

[0031] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] The dispensing needle ultrasonic cleaning device 1000 according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0074] Reference Figures 1 to 4As shown, the dispensing needle ultrasonic cleaning device 1000 provided according to the embodiment of the utility model comprises a fixing seat 10, an ultrasonic oscillating cleaning device 20, a blow dryer 30 and a main control device 40 connected to the ultrasonic oscillating cleaning device 20 for controlling the operation of the ultrasonic oscillating cleaning device 20;

[0075] The ultrasonic oscillation cleaner 20 has a cleaning chamber 201 with an open top, and the ultrasonic oscillation cleaner 20 and the main control device 40 are both mounted on the fixed seat 10; the blow dryer 30 is fixedly mounted beside the ultrasonic oscillation cleaner 20, and a needle inlet groove 301 is opened downwardly on its top, an air inlet pipe 302 connected to the needle inlet groove 301 is provided in the middle and upper part of its outer wall, and an exhaust pipe 303 connected to the needle inlet groove 301 is provided at its bottom.

[0076] Based on the above, it can be clearly seen that when the present application is implemented specifically, it is mainly used as a dispensing needle ultrasonic cleaning device 1000.

[0077] Specifically, when applying the present application, a certain amount of cleaning liquid is loaded in the cleaning chamber 201, and the dispensing needle to be cleaned is placed in the cleaning chamber 201, and the ultrasonic oscillation cleaner 20 is controlled to work by the main control device 40. When the high-frequency ultrasonic oscillation is performed for a preset time, the glue adhered to the inner wall, end and outer wall of the placed dispensing needle can be shaken off, so as to achieve all-round cleaning of the placed dispensing needle.

[0078] The use of the above-mentioned application will obviously have the following technical effects:

[0079] First, the present application adopts the principle of ultrasonic oscillation to achieve all-round cleaning of the placed dispensing needles. Due to the advantages of ultrasonic oscillation itself, it uses the high-frequency sound waves of ultrasound to generate oscillations, so that the glue adhered to the inner wall, end and outer wall of the placed dispensing needle can be completely shaken off, so that it can be thoroughly cleaned in all directions to facilitate its reuse, which can greatly reduce the economic cost during use.

[0080] Secondly, since the present application is also provided with the blow dryer 30, after the placed dispensing needle is cleaned, it can be inserted into the needle insertion slot 301, and hot air is blown into the needle insertion slot 301 from the air inlet pipe 302. The hot air is discharged from top to bottom through the exhaust pipe 303, so that the outer and inner surfaces of the dispensing needle inserted into the needle insertion slot 301 can be dried better, so that there is no water stain on it during subsequent use, which can better avoid wetting the circuit board and other products to be dispensed due to dripping of water stains, so that the present application has good reliability.

[0081] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0082] Furthermore, in the specific implementation, Figure 2 and Figure 3 As shown, according to an embodiment of the present utility model, a drainage port is opened outwardly at the bottom of the inner wall of the cleaning chamber 201, and a drainage pipe 50 with a switch valve is connected outwardly to the drainage port.

[0083] Therefore, after each use, the switch valve on the drain pipe 50 can be opened to drain the used cleaning liquid in the cleaning chamber 201 through the drain pipe 50, so that clean cleaning liquid can be installed therein to perform ultrasonic vibration cleaning on the dispensing needle that needs to be cleaned again.

[0084] Furthermore, in the specific implementation, continue to compare Figure 2 and Figure 3 As shown, according to an embodiment of the present utility model, a liquid inlet is opened outwardly at the upper portion of the inner wall of the cleaning chamber 201, and a liquid inlet pipe 60 with a switch valve is connected outwardly to the liquid inlet.

[0085] Therefore, after each use, the switch valve on the drain pipe 50 is opened to drain the used cleaning liquid in the cleaning chamber 201 through the drain pipe 50, and then, the switch valve on the drain pipe 50 is closed, and the switch valve on the inlet pipe 60 is opened, and a set amount of cleaning liquid can be injected into the cleaning chamber 201 through the inlet pipe 60, so as to facilitate ultrasonic oscillation cleaning of the dispensing needle that needs to be cleaned again.

[0086] Furthermore, in this technical solution, Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the utility model, the present application further comprises a liquid storage barrel 70 equipped with a cleaning liquid;

[0087] The liquid storage barrel 70 is fixedly mounted beside the fixing seat 10 , and an openable and closable sealing cover 701 is disposed at its upper end, and a liquid discharge connector 702 adapted to be connected to the liquid inlet end of the liquid inlet pipe 60 is disposed at its bottom.

[0088] From this, it can be clearly seen that, on the one hand, the present application comes with the liquid storage barrel 70 for storing cleaning liquid, so that the cleaning liquid stored therein can be transported to the cleaning chamber 201 through the liquid inlet pipe 60 for use when necessary; on the other hand, when the openable and closable sealing cover 701 is opened, it is convenient to add the required amount of cleaning liquid to the liquid storage barrel 70 regularly or irregularly, so that the present application can be used uninterruptedly.

[0089] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0090] Preferably, in this technical solution, continue to control Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the utility model, a flow regulating valve 703 connected to the interior of the liquid storage barrel 70 is provided on the top of the openable and closable sealing cover 701, and an air pump is connected between the flow regulating valve 703 and the main control device 40, which can supply air to the liquid storage barrel 70 to push the cleaning liquid in the liquid storage barrel 70 into the cleaning chamber 201 through the liquid inlet pipe 60.

[0091] In this regard, it is clear that when the present application is actually used, by adding the air pump, the liquid storage barrel 70 does not need to be installed very high so that the height of its bottom drainage joint 702 is equal to or higher than the height of the upper opening of the cleaning chamber 201. When its installation height is not high, the space occupied by the present application can be greatly reduced, so that when the present application is fixedly installed, the space occupied is small.

[0092] In addition, in a specific implementation, according to an embodiment of the utility model, the upper portion of the inner wall of the cleaning chamber 201 is flush with or slightly lower than the liquid inlet and is further provided with a liquid level detection port, and the liquid level detection port is externally connected to a liquid level detection sensor 80 connected to the main control device 40;

[0093] When the liquid level detection sensor 80 detects that the liquid level in the cleaning chamber 201 reaches the liquid level detection port, a signal can be transmitted to the main control device 40 so that the main control device 40 controls the air pump to stop supplying air to the liquid storage barrel 70 .

[0094] In this regard, it can be clearly understood that the present application is provided with the liquid level detection sensor 80 for monitoring the liquid level in the cleaning chamber 201 and controlling its operation. When the used cleaning liquid in the cleaning chamber 201 is drained and the cleaning liquid is loaded into the cleaning chamber 201, the cleaning liquid level can be monitored during the loading process so that the operator does not need to wait all the time. When the liquid level in the cleaning chamber 201 reaches the liquid level detection port, the signal can be transmitted to the main control device 40. At this time, the main control device 40 will control the air pump to stop supplying air to the liquid storage barrel 70, so as to stop infusing cleaning liquid into the cleaning chamber 201. In this way, the present application can be used conveniently and worry-free.

[0095] Furthermore, in this technical solution, Figure 1 , Figure 2 and Figure 3As shown, according to an embodiment of the utility model, the present application further comprises a sealing cover plate 90 for covering the upper opening of the cleaning chamber 201 and a driving device 100 connected to the main control device 40 for controlling the movement of the sealing cover plate 90 between the first position and the second position;

[0096] Among them, the connection end of the sealing cover plate 90 is fixed on the driving device 100; when the driving device 100 drives the sealing cover plate 90 to move to the first position, the sealing cover plate 90 covers the upper opening of the cleaning chamber 201; when the driving device 100 drives the sealing cover plate 90 to move to the second position, the sealing cover plate 90 opens the upper opening of the cleaning chamber 201.

[0097] Therefore, when using the present application, the dispensing needle that needs to be cleaned is placed in the cleaning chamber 201, and the upper opening is covered with the sealing cover plate 90, so that when the ultrasonic oscillation cleaner 20 is working, the cleaning liquid loaded in the cleaning chamber 201 is not easy to overflow through the upper opening.

[0098] Again, in a specific implementation, according to an embodiment of the present invention, the driving device 100 is a screw-driven linear module or a cylinder-driven linear module, and the driving device 100 is fixed on the fixed seat 10, on which a slider 110 is provided that can slide between the first position and the second position;

[0099] Based on this, in the present application, the connection end of the sealing cover plate 90 is fixed on the slider 110 .

[0100] For the above-mentioned driving device 100, when it is a screw-driven linear module or a cylinder-driven linear module, it belongs to the conventional linear module transmission component in the prior art, which can be directly purchased, installed and used in the existing market or on the Internet, so its details are not described in detail here.

[0101] It should be added that in the specific implementation, Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the utility model, the present application further includes a conical pressure member 120 for driving the sealing cover plate 90 to press against the upper opening of the cleaning chamber 201;

[0102] Among them, the control Figure 4As shown, the slider 110 includes an upper slider 1101, a lower slider 1102 and an elastic member 1103 connected between the upper slider 1101 and the lower slider 1102; the connection end of the sealing cover plate 90 is fixed on the upper slider 1101; the upper slider 1101 has a pressure groove 11011 opened along the up-down direction facing the outer wall of the ultrasonic oscillation cleaner 20; the conical pressure member 120 is transversely fixed on the outer wall of the ultrasonic oscillation cleaner 20, and its tip is facing the lower inner part of the pressure groove 11011;

[0103] Initially, the level of the sealing cover plate 90 is slightly higher than the level of the upper opening of the cleaning chamber 201. When the driving device 100 drives the sealing cover plate 90 to move to the first position, the pressure groove 11011 moves toward the conical pressure member 120, and the conical pressure member 120 presses the pressure groove 11011 downward to drive the upper slider 1101 to drive the sealing cover plate 90 to descend a preset stroke to press the upper opening of the cleaning chamber 201.

[0104] In this regard, it can be clearly understood that by providing the conical pressure member 120, through the extrusion and pressing principle, the sealing cover plate 90 can be driven to move a preset stroke while descending a preset stroke during the process of moving to the first position, so as to finally be driven to press the upper opening of the cleaning chamber 201. In this way, even when the ultrasonic oscillation cleaner 20 is working, the cleaning liquid loaded in the cleaning chamber 201 is indeed not easy to overflow through its upper opening.

[0105] At the same time, since the conical pressure member 120 is laterally fixed on the outer wall of the ultrasonic oscillation cleaner 20, and its tip is opposite to the lower inner part of the pressure groove 11011, when the driving device 100 drives the sealing cover plate 90 to move to the first position, the pressure groove 11011 moves toward the conical pressure member 120, and the conical pressure member 120 squeezes the pressure groove 11011 downward to drive the upper slider 1101 to drive the sealing cover plate 90 to descend a preset stroke to press the upper opening of the cleaning chamber 201. In this process, the conical pressure member 120 can also play a certain role in isolating and protecting the ultrasonic oscillation cleaner 20. On the basis of its own elastic resistance, when the upper slider 1101 moves to the first position, it will not hard hit the ultrasonic oscillation cleaner 20 due to the isolation protection and the elastic resistance applied by the conical pressure member 120, so that the service life of the ultrasonic oscillation cleaner 20 is long.

[0106] It is further necessary to add that, in the specific implementation, continue to compare Figure 4As shown, according to an embodiment of the present utility model, the elastic member 1103 includes two guide rods 11031 and two compression springs 11032;

[0107] Among them, the left and right sides of the lower sliding block 1102 are respectively provided with guide holes passing through the upper and lower end surfaces thereof, the two guide rods 11031 correspondingly pass through the two guide holes from bottom to top, the lower ends of which are respectively provided with a tightening outer edge 110311 which abuts against the lower bottom surface of the lower sliding block 1102, and the upper ends thereof are respectively connected to the bottom of the upper sliding block 1101; the two compression springs 11032 are correspondingly sleeved on the outside of the two guide rods 11031, and are limited between the bottom of the upper sliding block 1101 and the upper end surface of the lower sliding block 1102, and the two compression springs 11032 are initially in a natural state or a compressed state.

[0108] Therefore, it is clear that when the driving device 100 drives the sealing cover plate 90 to move to the first position, the pressure groove 11011 moves toward the conical pressure member 120, and the conical pressure member 120 presses the pressure groove 11011 downward to drive the upper slider 1101 to drive the sealing cover plate 90 to descend a preset stroke to press the upper opening of the cleaning chamber 201. In this process, the two compression springs 11032 are further compressed, and the two guide rods 11031 move downward along the two guide holes accordingly. On the contrary, when the driving device 100 drives the sealing cover plate 90 to move to the second position, the pressure groove 11011 will move away from the conical pressure member 120 to drive the upper slider 1101 to drive the sealing cover plate 90 to rise a preset stroke and away from the upper opening of the cleaning chamber 201 to open the upper opening of the cleaning chamber 201. During this process, the two compression springs 11032 will be reset to the initial state, and the two guide rods 11031 will correspondingly move upward along the two guide holes and reset to the initial state.

[0109] At the same time, it can also be clarified that the elastic member 1103 includes the two guide rods 11031 and the two compression springs 11032, and when the elastic member 1103 is assembled with the upper slider 1101 and the lower slider 1102 according to the above structure, the two compression springs 11032 of the elastic member 1103 can only be extended and retracted in the up-and-down direction, and can drive the upper slider 1101 to move only in the up-and-down direction, so that the pressure groove 11011 moves toward the conical pressure member 120, and the conical pressure member 120 When the pressure groove 11011 is squeezed downward, the upper slider 1101 can be driven to drive the sealing cover plate 90 to move to the first position. During this process, the upper slider 1101 can only descend within a preset stroke in the up and down directions to drive the sealing cover plate 90 to press the upper opening of the cleaning chamber 201. In this way, the elastic member 1103 has good reliability and stability in use, and the upper slider 1101 has good stability in up and down movement, and can more stably cooperate with the conical pressure member 120 to achieve linkage work.

[0110] It is further necessary to add that in the specific implementation, Figure 1 As shown, according to one embodiment of the present invention, the main control device 40 is covered with a first protective shell 130, and the sealing cover plate 90, the driving device 100 and the slider 110 are covered with a second protective shell 140, so that when the present application is actually working, the main control device 40, the sealing cover plate 90, the driving device 100 and the slider 110 are all well protected, and the present application is safer and more reliable to use.

[0111] It should also be added that, in the specific implementation, according to the dispensing needle ultrasonic cleaning device 1000 provided in the embodiment of the utility model, the cleaning liquid installed in the liquid storage barrel 70 is preferably cleaning alcohol, and the glue liquid required for cleaning is preferably AB glue.

[0112] Other embodiments and the like are not described here by way of example.

[0113] To sum up, the ultrasonic cleaning device 1000 for dispensing needles provided in the present application adopts the principle of ultrasonic oscillation in its specific implementation to achieve all-round cleaning of the placed dispensing needles. Due to the advantages of ultrasonic oscillation itself, it uses the high-frequency sound waves of ultrasound to generate oscillations, so that the glue adhered to the inner wall, end and outer wall of the placed dispensing needle can basically be completely shaken off, so that it can be thoroughly cleaned in all directions to facilitate its reuse, which can greatly reduce the economic cost during use.

[0114] Furthermore, since the present application is also provided with the blow dryer 30, after the placed dispensing needle is cleaned, it can be inserted into the needle insertion slot 301, and hot air can be blown into the needle insertion slot 301 from the air inlet pipe 302, and the hot air is discharged from top to bottom through the exhaust pipe 303, so that the outer and inner surfaces of the dispensing needle inserted into the needle insertion slot 301 can be dried better, so that there is no water stain on it during subsequent use, which can better avoid wetting the circuit board and other products to be dispensed due to dripping of water stains, so that the present application has good reliability.

[0115] In addition, the present application comes with the liquid storage barrel 70 for storing cleaning liquid, so that the cleaning liquid stored therein can be transported to the cleaning chamber 201 for use through the liquid inlet pipe 60 when needed. When the openable and closable sealing cover 701 is opened, it is convenient to add the required amount of cleaning liquid to the liquid storage barrel 70 regularly or irregularly, so that the present application can be used uninterruptedly.

[0116] Furthermore, the present application is provided with the liquid level detection sensor 80 for monitoring the liquid level in the cleaning chamber 201 and controlling its operation. When the used cleaning liquid in the cleaning chamber 201 is drained and the cleaning liquid is loaded into the cleaning chamber 201, the cleaning liquid level can be monitored during the loading process so that the operator does not need to wait all the time. When the liquid level in the cleaning chamber 201 reaches the liquid level detection port, the signal can be transmitted to the main control device 40. At this time, the main control device 40 will control the air pump to stop supplying air to the liquid storage barrel 70, so as to stop infusing cleaning liquid into the cleaning chamber 201. In this way, the present application is convenient and worry-free to use.

[0117] Again, by providing the conical pressure member 120, through the extrusion and pressing principle, the sealing cover plate 90 can be driven to move a preset stroke while descending a preset stroke during the process of moving to the first position, so as to finally be driven to press the upper opening of the cleaning chamber 201. In this way, even when the ultrasonic oscillation cleaner 20 is working, the cleaning liquid loaded in the cleaning chamber 201 is indeed not easy to overflow through its upper opening.

[0118] At the same time, since the conical pressure member 120 is laterally fixed on the outer wall of the ultrasonic oscillation cleaner 20, and its tip is opposite to the lower inner part of the pressure groove 11011, when the driving device 100 drives the sealing cover plate 90 to move to the first position, the pressure groove 11011 moves toward the conical pressure member 120, and the conical pressure member 120 squeezes the pressure groove 11011 downward to drive the upper slider 1101 to drive the sealing cover plate 90 to descend a preset stroke to press the upper opening of the cleaning chamber 201. In this process, the conical pressure member 120 can also play a certain role in isolating and protecting the ultrasonic oscillation cleaner 20. On the basis of its own elastic resistance, when the upper slider 1101 moves to the first position, it will not hard hit the ultrasonic oscillation cleaner 20 due to the isolation protection and the elastic resistance applied by the conical pressure member 120, so that the service life of the ultrasonic oscillation cleaner 20 is long.

[0119] Furthermore, the dispensing needle ultrasonic cleaning device 1000 provided in the present application is indeed extremely practical and has excellent use effect, which makes the present application bound to have a good market promotion value, and the present application is bound to be very popular and will be effectively popularized.
