Description

Technical Field

[0001] The present application relates to the field of glue dispensing technology, and in particular to a glue dispensing device. Background Art

[0002] During the production process, in order to allow the product to be pasted, potted, and fixed, it is usually necessary to manually or machine-dispense the product using a dispensing machine.

[0003] Currently, a glue dispenser is used to bond the camera and its housing. Because the glue in the dispenser's glue tube is extremely sticky, and when the remaining glue in the tube reaches one-third or one-quarter of its volume after use, the air pressure in the tube may be too low, preventing the remaining glue from flowing out. Alternatively, the remaining glue may still drip out intermittently, but at a low flow rate. This results in uneven glue distribution between the camera and its housing, easily creating small bubbles, which in turn causes poor airtightness at the bonded joint and renders the product scrapped. Generally, when the glue fails to flow out or flows out intermittently, a new glue tube is replaced and the old one discarded. However, since there is still unused glue in the old tube and the glue is expensive, this results in glue waste, which is not conducive to cost savings.

[0004] Therefore, how to provide a glue dispensing machine that can discharge the remaining glue in the glue tube is a technical problem that those skilled in the art urgently need to solve. Utility Model Content

[0005] The present application provides a glue dispensing device to solve the problem that the remaining glue in the tube body cannot flow out, thereby avoiding glue waste and saving production costs.

[0006] To achieve the above-mentioned object, the present application provides a dispensing device, which is applied to a tube body, the tube body being used to store a fluid, the tube body including an inlet end and an outlet end opposite to each other, and a movable member disposed between the inlet end and the outlet end, characterized in that the dispensing device includes a propulsion mechanism connected to the inlet end;

[0007] The propulsion mechanism includes a propulsion member extending through the inlet end to the interior of the tube body;

[0008] The pushing member pushes the movable member to move in the direction from the inlet end to the outlet end so as to discharge the remaining fluid through the outlet end.

[0009] Among them, when the remaining fluid in the tube body reaches a preset value, the problem of the fluid being unable to flow out will occur. Through the setting of the propulsion mechanism, the propulsion member is controlled to abut against the movable member and then squeeze the gas inside the tube body, so that the gas is compressed and the gas pressure increases, and then the remaining fluid is discharged using the gas, thereby avoiding the waste of the remaining fluid in the tube body, improving the utilization rate of the fluid, and saving production costs.

[0010] Preferably, the length of the propulsion member is not less than the length of the tube body.

[0011] Among them, if the length of the propulsion member is shorter than the length of the tube body, when the propulsion member continues to advance to the limit in the depth direction of the tube body, due to the length limitation, the gas in the tube body is not compressed enough, the pressure is still very small, and no major change occurs, resulting in the remaining fluid still unable to be discharged. Therefore, the length of the propulsion member is set to be no less than the length of the tube body, so that the propulsion member can adapt to and reach any position in the tube body, squeeze the gas in the tube body, and gradually increase the pressure to discharge the remaining fluid from the tube body.

[0012] Preferably, the dispensing device further comprises a connecting mechanism and a plurality of sealing members;

[0013] One end of the connecting mechanism is sleeved on a side of the tube body having an inlet end, and is used to connect the tube body and the propulsion mechanism;

[0014] The connecting mechanism comprises a through hole, the pushing member passes through the through hole and the inlet end in sequence and extends to the interior of the tube body, and the sealing member is arranged between the pushing member and the through hole.

[0015] Among them, the setting of the connecting mechanism ensures the stability of the connection between the propulsion mechanism and the tube body, and the setting of the sealing member ensures that the gas in the tube body will not be squeezed and flow out from between the propulsion member and the through hole when the propulsion mechanism performs the propulsion operation, resulting in insufficient air pressure in the tube body.

[0016] Preferably, the dispensing device further comprises a dispensing mechanism connected to the outlet end, the dispensing mechanism comprising a fluid collecting mechanism and a liquid outlet assembly;

[0017] The fluid collecting mechanism is used to store the fluid flowing out of the tube body. One end of the fluid collecting mechanism is connected to the outlet end, and the other end is connected to the liquid outlet component. The liquid outlet component is used to spray the fluid in the fluid collecting mechanism.

[0018] Among them, the fluid collection mechanism is used to temporarily store fluid for the dispensing mechanism, and then discharge the fluid in the fluid collection mechanism through the liquid outlet component.

[0019] Preferably, the liquid outlet assembly includes a nozzle and a mounting structure;

[0020] The mounting structure is connected to the fluid collecting mechanism, and the nozzle is arranged in the mounting structure and communicated with the fluid collecting mechanism;

[0021] The length of the nozzle is greater than the length of the mounting structure.

[0022] Among them, the setting of the mounting structure ensures the stability of the installation of the liquid outlet component and the safety of the nozzle. The nozzle length is greater than the length of the mounting structure, which ensures that the nozzle will not splash the fluid onto the mounting structure when performing the liquid spraying operation, thereby improving the cleanliness of the equipment.

[0023] Preferably, the dispensing mechanism further comprises a piston assembly and a sealing member;

[0024] One end of the sealing member is connected to the piston assembly, and the other end extends into the fluid collection mechanism. It is used to move in a direction close to the nozzle under the drive of the piston assembly to seal the nozzle so that the fluid cannot flow out, or to move in a direction away from the nozzle under the drive of the piston assembly to open the nozzle to allow the fluid to flow out.

[0025] Among them, the coordinated use of the piston assembly and the sealing piece can accurately control the flow rate of the fluid during the dispensing process, so that the fluid can be discharged according to demand.

[0026] Preferably, the dispensing mechanism further includes a driving mechanism;

[0027] The driving mechanism is connected to the piston assembly and is used to drive the piston assembly to move.

[0028] The driving mechanism drives the piston assembly to move, so as to move the blocking member, thereby blocking or opening the nozzle.

[0029] Preferably, the dispensing mechanism further comprises an air pipe and a chamber provided on one side of the fluid collecting mechanism, and the driving mechanism comprises an air supply source for providing an air source;

[0030] The air pipe is connected to the chamber and the air supply source;

[0031] The piston assembly is arranged in the chamber, above the air pipe. When the air supply source is working, the piston assembly is lifted up from the initial position in the direction away from the inlet end by the air supply source. When the air supply source is suspended, the piston assembly moves in the direction close to the inlet end and returns to the initial position.

[0032] When the piston assembly is in the initial position, the nozzle is in a closed state.

[0033] Among them, gas is used to drive the movement of the piston assembly. As the amount of gas in the chamber increases, the height of the piston assembly also increases. As the amount of gas in the chamber decreases, the piston assembly slowly descends until it returns to its original position.

[0034] Preferably, the dispensing device further comprises a first regulating mechanism, one end of which is connected to the outlet end and the other end is connected to the fluid collecting mechanism, for regulating the flow rate of the fluid flowing from the tube body to the fluid collecting mechanism.

[0035] The provision of the first regulating mechanism ensures the stability of the flow rate of the fluid from the tube body to the fluid collecting mechanism, while providing a certain buffer for the flow of the fluid.

[0036] Preferably, the dispensing equipment also includes a second adjustment mechanism, which is connected to the piston assembly and is used to adjust the movement distance of the piston assembly, change the maximum distance between the sealing member and the nozzle, and control the size and / or shape of the fluid flowing out of the nozzle.

[0037] Among them, the greater the distance between the blocking piece and the nozzle, the greater the flow rate of the fluid through the nozzle, and the smaller the distance between the blocking piece and the nozzle, the smaller the flow rate of the fluid through the nozzle; the size and / or shape of the fluid when sprayed from the nozzle will also be affected by the size of the flow rate.

[0047] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0048] As described in the background art, the glue in the glue dispenser's glue tube is extremely sticky, and when the remaining glue in the tube reaches one-third or one-quarter of its volume after use, the air pressure in the tube will be too low, preventing the remaining glue from flowing out of the tube. Alternatively, the remaining glue may still drip out intermittently, but at a low flow rate, resulting in uneven glue distribution between the camera and its housing, easily generating small bubbles, which in turn causes poor airtightness at the bonding joint and leads to product failure. Generally, when the glue fails to flow out or flows out intermittently, a new glue tube is replaced and the old one discarded. However, since there is still unused glue in the old tube and the glue is expensive, this results in glue waste, which is not conducive to cost savings.

[0049] Therefore, the present application provides a glue dispensing device, which adds a propulsion mechanism to the tube body, aiming to solve the problem that the remaining glue in the tube body cannot flow out.

[0050] The dispensing equipment is mainly composed of a propulsion mechanism and a dispensing mechanism, which is applied to the tube body. The tube body stores fluid, and the tube body is connected to the propulsion mechanism and the dispensing mechanism respectively. The propulsion mechanism is used to discharge the fluid in the tube body and allow the fluid to flow into the dispensing mechanism. The dispensing mechanism is used to spray the fluid for dispensing operations.

[0051] refer to Figures 1 to 3 As shown in the dispensing equipment diagram, the dispensing equipment is applied to a tube body 10, which is used to store fluid. The tube body includes an opposite inlet end 11 and an outlet end 12, and a movable part 13 arranged between the inlet end 11 and the outlet end 12. The dispensing equipment includes a propulsion mechanism 20 connected to the inlet end 11; the propulsion mechanism 20 includes a propulsion member 21, which extends through the inlet end 11 to the interior of the tube body 10; the propulsion member 21 pushes the movable part 13 to move in the direction from the inlet end 11 to the outlet end 12 to discharge the remaining fluid through the outlet end 12.

[0052] In some embodiments of the present application, the tube body 10 is a glue tube, in which the fluid stored therein may be glue, which is used to bond electronic devices and their housings. Regardless of whether the glue tube is full of glue or there is residual glue that cannot be discharged, the glue in the glue tube can be discharged by adding a propulsion mechanism 20 to the glue tube. The working process is as follows: first, the glue tube is straightened, and the propulsion mechanism 20 is installed at the inlet end of the glue tube so that the propulsion member 21 enters the interior of the glue tube; then, the glue dispensing mechanism 40 is installed at the outlet end of the glue tube; then, the propulsion member 21 starts to propel from the initial position in the direction close to the movable member, and during the propulsion process, it abuts against the movable member, driving the movable member to move synchronously to discharge the glue in the glue tube into the glue dispensing mechanism 40; finally, the glue dispensing operation is performed using the glue dispensing mechanism 40, and after the glue dispensing operation is completed, the propulsion member 21 returns to its initial position.

[0053] In one embodiment of the present application, the glue stock in the tube body 10 is not full. When not in use, there is a certain distance between the top of the glue and the inlet end 11; the movable part 13 is located at the top of the glue, close to the glue, and its position in the tube body 10 decreases as the amount of glue decreases. The glue cannot overflow from the movable part 13. At this time, the propulsion part 21 is used to push the movable part 13 to move, so that the movable part 13 directly squeezes the remaining glue and discharges it through the outlet end 12.

[0054] In another embodiment of the present application, the movable part 13 in the tube body 10 is in close contact with the glue in the initial state, but the position of the movable part 13 in the tube body 10 will not decrease as the amount of glue decreases. When the amount of glue decreases to a certain extent, the air pressure between the movable part 13 and the glue decreases, resulting in the glue being unable to flow out on its own. At this time, the control propulsion part 21 applies a certain force to abut the movable part 13, pushing the movable part 13 to move downward, thereby squeezing the gas between the movable part 13 and the glue, compressing the gas, increasing the gas pressure, and then using the gas to discharge the remaining glue, thereby avoiding the waste of the remaining glue in the tube body, improving the utilization rate of the glue, and saving production costs.

[0055] In another embodiment of the present application, there is always gas at a certain pressure between the movable part 13 and the glue in the tube body 10, and the position of the movable part 13 will decrease as the amount of glue decreases. When the amount of glue decreases to a certain extent, the remaining glue cannot flow out by itself. At this time, the control propulsion member 21 is controlled to abut the movable part 13, pushing it to move downward, thereby squeezing the gas between the movable part 13 and the glue, so that the gas is compressed and the gas pressure increases, and the remaining glue is discharged through the outlet end 12 using the gas in between.

[0056] In some embodiments of the present application, the movable part 13 is a small piston, and a rubber ring is provided between the small piston and the inner wall of the tube body 10 to prevent the glue from flowing back and adhering to the inner wall of the tube body 10 .

[0057] In some embodiments of the present application, the propulsion mechanism 20 is a cylinder, and the propulsion member 21 is the output shaft of the cylinder. When the propulsion mechanism 20 is started, the output shaft is controlled to abut against the movable member 13, and the output shaft propels the movable member 13 forward along the length direction of the cylinder, that is, from the inlet end 11 to the outlet end 12, so that the gas in the tube body 10 is squeezed and compressed, the pressure of the gas increases, and the remaining fluid is discharged using the gas. It should be noted that the propulsion mechanism 20 can be automatically started when the amount of fluid in the tube body 10 reaches a preset value, which is one-third of the total amount of fluid. At this time, the fluid in the tube body 10 cannot flow out by inertia due to insufficient air pressure, and the propulsion mechanism 20 is needed to increase the air pressure in the tube body 10 to discharge the remaining fluid. In this way, the waste of the remaining fluid in the tube body 10 is avoided, the utilization rate of the fluid is improved, and production costs are saved; in addition, the propulsion mechanism 20 can also be manually started when the amount of fluid in the tube body 10 is sufficient. Through the cooperation of the propulsion member 21 and the movable member 13, the gas in the tube body 10 is squeezed, the gas pressure is further increased, and the flow rate and pressure of the fluid when it flows out from the outlet end 12 are increased.

[0058] In all the following embodiments, the movable member in the tube body is initially in close contact with the glue, and the position of the movable member does not drop as the amount of glue decreases.

[0059] Preferably, reference Figures 1 to 3 In the dispensing equipment diagram shown, the length of the pusher 21 is not less than the length of the tube body 10 .

[0060] In some embodiments of the present application, the propulsion mechanism 20 is a pen-shaped cylinder, and the propulsion member 21 is the output shaft of the pen-shaped cylinder. Compared with ordinary cylinders, the pen-shaped cylinder has a longer output shaft. In the case of an ordinary cylinder, the length of the output shaft of the ordinary cylinder is much smaller than the length of the tube body 10. During the propulsion process in the tube body 10, when the output shaft is pushed to the limit, due to the length limitation, the output shaft cannot continue to extend toward the inside of the tube body 10. The gas in the tube body 10 is not compressed enough, the pressure remains very small, and no significant change occurs. The fluid still cannot flow out through the extrusion of the gas. In the case of a pen-shaped cylinder, the length of the output shaft of the pen-shaped cylinder is greater than or equal to the length of the tube body 10. During the propulsion process in the tube body 10, it is not limited by the length of the output shaft itself. The output shaft can be pushed to any position in the tube body 10, thereby squeezing the gas in the tube body 10, gradually increasing the pressure, and expelling the remaining fluid from the tube body 10.

[0061] Preferably, reference Figures 1 to 3As shown in the dispensing equipment diagram, the dispensing equipment also includes a connecting mechanism 30 and several sealing members (not shown in the figure); the connecting mechanism 30 is sleeved on a side of the tube body 10 having the inlet end 11, and is used to connect the tube body 10 and the propulsion mechanism 20; the connecting mechanism 30 includes a through hole (not shown in the figure), and the propulsion member 21 extends through the through hole and the inlet end 11 in sequence to the interior of the tube body 10, and the sealing member is arranged between the propulsion member 21 and the through hole.

[0062] In some embodiments of the present application, the connection mechanism 30 employs a sleeve structure near the inlet end 11 to protect the tube body 10, preventing contaminants from entering the tube body 10 through the inlet end 11, and thus preventing the tube body 10 from being contaminated and damaged during use. The upper end of the connection mechanism 30 and the lower end of the propulsion mechanism 20 may be fixedly connected by bolts or screws to improve the stability of the connection.

[0063] In some embodiments of the present application, the through hole of the connecting mechanism 30 and the inlet end 11 of the tube body 10 are aligned vertically, so that the pushing member 21 can pass through the two.

[0064] In some embodiments of the present application, the radius of the through hole is larger than the radius of the propeller 21, and there is a gap between the two. A seal is arranged between the through hole and the propeller 21. The outer ring of the seal is fixed to the through hole, and the inner ring is in contact with and fits with the propeller 21. In this way, when the propeller 21 moves, the external air of the tube body 10 will not enter the inside of the tube body 10, and the internal air pressure of the tube body 10 will not be disturbed, thereby avoiding the situation where the air pressure of the tube body 10 is unstable due to internal and external air mixing, and the fluid cannot be discharged by extrusion.

[0065] Furthermore, based on the aforementioned solution, relevant components of a dispensing mechanism of a dispensing device are provided to discharge the fluid evenly to achieve a dispensing operation.

[0066] Preferably, reference Figures 1 to 3 As shown in the dispensing equipment diagram, the dispensing equipment also includes a dispensing mechanism 40 connected to the outlet end, and the dispensing mechanism 40 includes a fluid collecting mechanism 41 and a liquid outlet component 42; the fluid collecting mechanism 41 is used to store the fluid flowing out of the tube body 10, one end of which is connected to the outlet end 12, and the other end is connected to the liquid outlet component 42, and the liquid outlet component 42 is used to spray the fluid in the fluid collecting mechanism 41.

[0067] In some embodiments of the present application, the volume of the fluid collecting mechanism 41 is smaller than that of the tube body 10 , and it receives the fluid flowing out of the tube body 10 and temporarily stores it so that the fluid can be sprayed out through the liquid outlet component 42 in a subsequent dispensing operation.

[0068] Preferably, reference Figures 1 to 3As shown in the dispensing equipment diagram, the liquid outlet component 42 includes a nozzle 420 and a mounting structure 421; the mounting structure 421 is connected to the fluid collection mechanism 41, and the nozzle 420 is arranged in the mounting structure 421 and is connected to the fluid collection mechanism 41; wherein, the length of the nozzle 420 is greater than the length of the mounting structure 421.

[0069] Among them, the setting of the mounting structure 421 ensures the stability of the installation of the liquid outlet component 42 and the safety of the nozzle 420. The length of the nozzle 420 is greater than the length of the mounting structure 421, which ensures that the nozzle 420 will not splash the fluid to the mounting structure 421 when performing the liquid spraying operation, thereby improving the cleanliness of the equipment.

[0070] In some embodiments of the present application, the fluid collecting mechanism 41 includes an extension structure 410 extending along the length direction of its body, and the mounting structure 421 is connected to the extension structure 410, and both have a channel inside for the nozzle 420 to pass through.

[0071] In some embodiments of the present application, a fluid outlet (not shown in the figure) is provided at the bottom end of the fluid collecting mechanism 41 , and the inlet end of the nozzle 420 is connected to the fluid outlet of the fluid collecting mechanism 41 .

[0072] Preferably, reference Figures 1 to 3 As shown in the dispensing device diagram, the dispensing device also includes a first regulating mechanism 50 , one end of which is connected to the outlet end 12 , and the other end is connected to the fluid collecting mechanism 41 , for regulating the flow of the fluid from the tube body 10 to the fluid collecting mechanism 41 .

[0073] In some embodiments of the present application, the first regulating mechanism 50 uses a flow regulating valve to provide a flow channel for the circulation of the fluid. It can also adjust the flow rate of the fluid flowing from the tube body 10 to the fluid collection mechanism 41 according to the operating state of the device, providing a certain buffer for the flow of the fluid. In some cases, the amount of fluid in the fluid collection mechanism 41 is small and insufficient to support the subsequent dispensing operation, so the flow regulating valve is adjusted to increase the flow rate of the fluid flowing out of the tube body 10. In other cases, the amount of fluid in the fluid collection mechanism 41 is sufficient and does not need to be added, so the flow regulating valve is adjusted to close the connection between the tube body 10 and the fluid collection mechanism 41, so that the fluid in the tube body 10 cannot flow into the fluid collection mechanism 41.

[0074] Preferably, reference Figures 1 to 3 The dispensing equipment diagram shown, and Figure 3 and Figure 4As shown in the state schematic diagram, the dispensing mechanism 40 also includes a piston assembly 100 and a sealing member 110; one end of the sealing member 110 is connected to the piston assembly 100, and the other end extends into the fluid collection mechanism 41, and is used to move in a direction close to the nozzle 420 under the drive of the piston assembly 100 to close the nozzle 420 so that the fluid cannot flow out, or, move in a direction away from the nozzle 420 under the drive of the piston assembly 100 to open the nozzle 420 to allow the fluid to flow out.

[0075] Among them, the piston assembly 100 and the sealing member 110 work together, the piston assembly 100 is used to push the sealing member 110, and the sealing member 110 directly controls the flow of the fluid; when the sealing member 110 moves toward the nozzle 420 under the drive of the piston assembly 100, the end of the sealing member 110 close to the nozzle 420 is tightly abutted against the nozzle 420, closing the nozzle 420, thereby preventing the fluid from flowing out, ensuring that the fluid will not flow out when the dispensing operation is not performed; on the contrary, when the sealing member 110 moves away from the nozzle 420 under the drive of the piston assembly 100, the end of the sealing member 110 close to the nozzle 420 is disconnected from the nozzle 420, and the nozzle 420 is opened, so that the fluid in the fluid collection mechanism 41 flows smoothly through the nozzle 420 for dispensing, thereby achieving precise control of the fluid flow, improving the accuracy and reliability of the dispensing process, and also reducing the waste of fluid and the risk of contamination during operation.

[0076] In some embodiments of the present application, the size of the contact end between the blocking member 110 and the nozzle 420 is equal to or slightly smaller than the size of the nozzle 420 inlet, so as to achieve a good blocking effect.

[0077] Preferably, reference Figures 1 to 3 As shown in the dispensing equipment diagram, the dispensing mechanism 40 also includes a driving mechanism (not shown in the figure); the driving mechanism is connected to the piston assembly and is used to drive the piston assembly to move.

[0078] The driving mechanism may be a motor driving device or a gas driving device.

[0079] In some embodiments of the present application, the driving mechanism adopts a motor, and the forward and reverse rotation of the motor's driving shaft drives the piston assembly to move up and down, so that the blocking member moves up and down synchronously with the piston assembly, thereby blocking or opening the nozzle 420.

[0080] In another preferred embodiment of this application, refer to Figures 1 to 3 The dispensing equipment diagram shown, and Figure 3 and Figure 4As shown in the state schematic diagram, the dispensing mechanism 40 also includes an air pipe 43 and a chamber 200 arranged on one side of the fluid collecting mechanism 41, and the driving mechanism includes an air supply source 300, which is used to provide an air source; the air pipe 43 connects the chamber 200 and the air supply source 300; the piston assembly 100 is arranged in the chamber 200, above the air pipe 43, and when the air supply source 300 is working, the piston assembly 100 is lifted up from the initial position in the direction away from the nozzle 420 by the air source, and when the air supply source 300 is paused, the piston assembly 100 moves in the direction close to the nozzle 420 and resets to the initial position; wherein, when the piston assembly 100 is in the initial position, the nozzle 420 is in a closed state.

[0081] The gas supply source 300 uses a central gas supply device, which uses gas pressure increase and pressure reduction to drive the movement of the piston assembly 100. It should be noted that the gas outlet of the gas pipe 43 must be located below the piston assembly 100. If it is flush or located above, the piston assembly cannot be lifted by the air flow. As the amount of gas in the chamber 200 increases, Figure 4 As shown, the piston assembly 100 is lifted up in the direction 1 away from the nozzle, and the sealing member 110 and the nozzle 420 are disconnected, and the nozzle 420 is opened, so that the fluid in the fluid collection mechanism 41 flows out smoothly through the nozzle 420 for dispensing. As the amount of gas in the chamber 200 decreases, as shown in FIG. Figure 5 As shown, the height of the piston assembly 100 falling in the direction 2 close to the nozzle decreases accordingly, and slowly decreases until it returns to its original position, and then the blocking member 110 abuts against the nozzle 420, and the nozzle 420 is blocked, so that the fluid in the fluid collection mechanism 41 cannot flow out through the nozzle 420.

[0082] Preferably, reference Figures 1 to 3 The dispensing equipment diagram shown, and Figure 3 and Figure 4 As shown in the state schematic diagram, the dispensing equipment also includes a second adjustment mechanism 60, which is connected to the piston assembly 100 and is used to adjust the moving distance of the piston assembly 100, change the maximum distance between the sealing member 110 and the nozzle 420, and control the size and / or shape of the fluid when flowing out of the nozzle.

[0083] It should be noted that the greater the distance between the blocking member 110 and the nozzle 420, the greater the amount of fluid flowing through the nozzle 420, while the smaller the distance between the blocking member 110 and the nozzle 420, the smaller the amount of fluid flowing through the nozzle 420. The size and / or shape of the fluid when it is ejected from the nozzle 420 is also affected by the flow rate. The second adjustment mechanism 60 uses a stroke adjustment member. For example, by adjusting the second adjustment mechanism, the maximum distance between the blocking member 110 and the nozzle 420 is made to be the first distance, or the maximum distance between the blocking member 110 and the nozzle 420 is made to be the second distance, wherein the first distance is greater than the second distance; when the maximum distance between the blocking member 110 and the nozzle 420 is the first distance, it means that the higher the piston assembly 100 is lifted by the gas, the larger the upper limit of the movable distance range of the blocking member 110 is, and when the movable distance reaches the maximum value, the amount of fluid passing through the nozzle 420 also reaches the maximum; at the same time, the shape of the fluid when flowing out of the nozzle 420 will also be affected by the distance between the blocking member 110 and the nozzle 420. When the distance between the blocking member 110 and the nozzle 420 remains at a larger value, the shape of the fluid is approximately strip-shaped, and when the distance between the blocking member 110 and the nozzle 420 remains at a smaller value, the shape of the fluid is approximately point-shaped.

[0084] In some embodiments of the present application, the second adjustment mechanism 60 is disposed at the top of the chamber 200 and extends through the top of the chamber 200 to connect to the piston assembly 100. Rotating the second adjustment mechanism 60 in a first direction increases the upper limit of the maximum distance between the blocking member 110 and the spray head 420, for example, to the first distance, thereby increasing the movable range of the blocking member 110. Rotating the second adjustment mechanism 60 in a second direction decreases the upper limit of the maximum distance between the blocking member 110 and the spray head 420, for example, to the second distance, thereby decreasing the movable range of the blocking member 110. The second direction is opposite to the first direction.
