Description

Technical Field

[0001] This invention relates to the field of filling equipment technology, and more particularly to an automatic filling machine for detergent production. Background Technology

[0002] In the industrial production of liquid products such as detergents and disinfectants, automatic filling machines are crucial downstream packaging equipment. Their core task is to accurately, efficiently, and cleanly fill liquids into various packaging containers. Filling accuracy, efficiency, and the ability to control materials directly affect product cost control, appearance quality, and production efficiency.

[0003] In existing technologies, for liquids where excessive air bubbles need to be avoided during filling, an insertion-type filling method is often used. This involves inserting the filling tube deep into the bottom of the container, gradually raising the liquid level during filling, and keeping the tube end inserted at the bottom to reduce air bubble generation from impact. However, this method has significant technical drawbacks in practical applications.

[0004] After filling, the filling tube is withdrawn from the filled container. Because the tube is inserted to its deepest point, a significant amount of cleaning agent liquid will inevitably adhere to its outer wall. This residual liquid will drip during removal, resulting in material waste and increased production costs. Furthermore, the dripping liquid may contaminate the container's outer wall, the conveyor line, or the working environment, affecting product appearance, requiring additional cleaning processes, and reducing production efficiency. If different types or scents of cleaning agents are filled, the residual liquid may also lead to cross-contamination.

[0005] After filling stops, because the pipe section inserted into the container cannot be fitted with a valve structure, a large amount of cleaning agent remains between the valve located outside the pipe section and the pipe section. During the process of lifting and moving the filling pipe out, this remaining cleaning agent will re-enter the container due to gravity, causing the actual filling volume to greatly exceed the preset target and seriously affecting the metering accuracy. Summary of the Invention

[0006] This application provides an automatic filling machine for detergent production, solving the problem in the prior art where, after filling, a large amount of detergent liquid inevitably adheres to the outer wall of the filling tube when it is pulled out of the filled container. This residual liquid drips during the removal process; after filling stops, because the tube section inserted into the container cannot be fitted with a valve structure, a large amount of detergent remains between the valve and the tube section outside the tube. During the lifting and removal of the filling tube, this remaining detergent re-enters the container due to gravity, causing the actual filling volume to greatly exceed the preset target, seriously affecting the metering accuracy. The solution addresses this problem by using an airbag under the buoyancy of the liquid during filling, which lifts the mounting plate, liquid tube, and hose with the liquid level. Only the hose and the lower part of the airbag come into contact with the detergent, preventing large-area detergent adhesion to the liquid tube. When pulled out, the airbag inflates and seals the hose, preventing internal residual detergent from dripping and ensuring accurate filling volume. As the airbag rises, it fits against the bottle mouth, and the bottle mouth scrapes off the detergent adhering to the surface of the airbag, reducing waste and cleaning difficulties.

[0007] This application provides an automatic filling machine for detergent production, including a filling assembly, which includes a height adjustment component, an adjustment component, and a buoyancy component;

[0008] The height adjustment component includes a mounting plate;

[0009] The buoyancy components include liquid pipes, hoses, air bladders, connecting rods, and an air pump.

[0010] Mounting plates and hoses are fixed at the upper and lower ends of the liquid tube, respectively.

[0012] The airbag is used to press inwards to seal the hose;

[0013] The two ends of the connecting rod are respectively mounted on the mounting plate and the airbag;

[0014] During filling, the air bladder is lifted by the buoyancy of the liquid, causing the mounting plate and liquid tube to rise in height.

[0015] The adjusting element is installed on the mounting plate and the liquid pipe. The adjusting element is used to adjust the filling rate. When the height of the mounting plate and the liquid pipe is raised, the resistance of the adjusting element increases, thereby reducing the filling rate.

[0016] As an improvement, the adjusting components include a connecting frame, a positioning plate, a lifting port, a sliding port, a conductive plate, a collar, and a resistance bar;

[0017] The connecting bracket is fixed to one side of the positioning plate;

The negative terminal of the power supply is connected to the negative terminal of the liquid pump, the positive terminal of the liquid pump is electrically connected to the collar, and the positive terminal of the power supply connected to the liquid pump is electrically connected to the conductive disk.

[0030] The power supply, the pump, the conductive plate, the collar, and the resistor bar connected to the liquid pump form a complete circuit loop.

[0031] As the liquid pipe drives the collar to gradually rise along the height of the resistance bar, the resistance increases and the power of the liquid pump decreases.

[0032] As an improvement, the buoyancy component also includes an annular ring;

[0033] The ring is circular and hollow inside;

[0034] The airbag has a ring-shaped cylindrical structure, and the airbag is C-shaped and set outside the ring.

[0036] The C-shaped airbag abuts against the connecting rod at both ends;

[0037] The upper end of the connecting rod is connected to the output end of the air pump, and the cavity of the connecting rod is connected to the cavity of the annular ring.

[0038] The filling assembly also includes an air supply port;

[0039] Both the airbag and the ring have air supply ports, and the air supply ports of the airbag and the ring are connected to each other.

[0040] The gas output from the air pump enters the airbag through the connecting rod, the ring, and the air supply port.

[0041] As an improvement, the filling assembly also includes two clamps, which are symmetrically arranged on the conveyor belt support.

[0047] There are two connecting plates, which are symmetrically fixed on both sides of the mounting plate.

[0048] The connecting plate is made of iron;

[0049] The sliding sleeve and the telescopic rod each correspond to one of the two connecting plates;

[0050] The sliding sleeve is fixed on the base, located on one side of the conveyor belt, and the output end of the sliding sleeve is fixed below the connecting plate;

[0051] The second telescopic rod is fixed on the base and is located on the side of the conveyor belt away from the sliding sleeve. An electromagnet is fixed to the upper end of the second telescopic rod.

[0052] As an improvement, the buoyancy components also include a flow divider, uprights, and positioning rods;

[0053] The two ends of the positioning rod are fixed to the inner wall of the liquid pipe, and the upright is fixed to the lower side of the positioning rod;

[0054] The flow divider is a frustum shape, with the upper side of the flow divider fixed to the lower side of the upright.

[0055] The splitter is located below the hose;

[0056] The upper end of the positioning rod is pointed, and the cross-section of the positioning rod is triangular. The upright rod is cylindrical, and the diameter of the upright rod is the same as the diameter of the upper end of the flow divider.

[0057] As an improvement, the adjusting component also includes a second sliding port;

[0058] The positioning plate has a second sliding opening;

[0059] It also includes a dispersion component, which includes an air supply pipe, an air blowing ring, air holes, and an air pump.

[0060] The air ring is circular and hollow inside. The air ring is set on the outer ring of the airbag, and air holes are opened on the outer ring of the air ring.

[0061] During filling, the lower side of the air blowing ring and the upper side of the air bladder are on the same horizontal plane;

[0062] The air supply pipe is fixed on the air blowing ring. The air supply pipe is hollow inside and is connected to the air blowing ring.

[0063] The air supply pipe is slidably installed in the second sliding port. The upper end of the air supply pipe is fixed to the mounting plate. The second air pump is fixed to the mounting plate. The output end of the second air pump is connected to the air supply pipe.

[0064] The airflow velocity from the vent is 0.5-1.5 m / s.

[0065] As an improvement, there are multiple pores, which are evenly spaced in a ring shape;

[0066] The air vents are inclined relative to the liquid surface, forming an angle of 30-40 degrees.

[0067] As an improvement, the two ends of the airbag are fixed to the ring in a ring shape;

[0068] The air supply ports are located at both ends of the airbag, which is fixed to the ring.

[0071] There are multiple reset ropes, which are distributed in a ring at intervals.

[0072] The reset rope is an elastic rope.

[0073] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0074] Firstly, during filling, the airbag, buoyed by the liquid, lifts the mounting plate, liquid tube, and hose along with the liquid level. Only the hose and the lower part of the airbag come into contact with the cleaning agent, preventing large areas of the liquid tube from adhering to the cleaning agent. When pulled out, the airbag inflates and seals the hose, preventing residual cleaning agent from dripping and ensuring accurate filling volume. As the airbag rises, it fits against the bottle mouth, and the bottle mouth scrapes off the cleaning agent adhering to the surface of the airbag, reducing waste and cleaning difficulties. A circuit is formed by the external power supply, the pump, the conductive plate, the collar, and the resistance strip. As the liquid level rises, the collar moves along the resistance strip, increasing the resistance and reducing the power of the pump, thereby reducing the filling rate and preventing liquid overflow.

[0075] Secondly, air is supplied through a two-way air-blowing ring by an air pump. The gas is discharged from the inclined air holes, blowing the air bubbles that accumulate around the airbag towards the edge, preventing air bubbles from adhering to the airbag and affecting the accuracy of buoyancy. This ensures that the airbag is in close contact with the liquid surface rather than air bubbles, making the liquid level detection more accurate, thereby improving the reliability of filling rate adjustment.

[0076] Thirdly, the airbag is fixed to the ring at both ends. When pulled out, it rotates and rubs against the bottle opening, squeezing out the attached cleaning agent, causing it to collect and drip back into the bottle. Under its own elasticity and the tension of the reset rope, the airbag vibrates and deforms. Through rotation and vibration, the residual cleaning agent is collected back into the bottle, preventing external dripping, reducing waste and subsequent cleaning work. Attached Figure Description

[0093] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0094] Example 1: As Figures 1-9 As shown, this application discloses an automatic filling machine for detergent production, including a filling assembly 100. The filling assembly 100 includes a base 110, a vertical plate 120, a conveyor belt 130, a clamping component 140, a height adjustment component 150, a liquid supply component 160, an adjusting component 170, a buoyancy component 180, and an air supply port 190.

[0095] The height adjustment component 150 includes a sliding sleeve 151, a connecting plate 152, a mounting plate 153, a telescopic rod 154, and an electromagnet 155;

[0096] The buoyancy component 180 includes a liquid pipe 181, a hose 182, a diverter 183, a vertical rod 184, a positioning rod 185, an annular ring 186, an airbag 187, a connecting rod 188, and an air pump 189.

[0097] The upper and lower ends of the liquid pipe 181 are respectively fixed with mounting plates 153 and hoses 182;

[0098] The airbag 187 is installed outside the hose 182, and the air pump 189 is fixed on the mounting plate 153. The air pump 189 is connected to the airbag 187.

[0099] Airbag 187 is used to press inward to seal hose 182;

[0100] The two ends of the connecting rod 188 are respectively mounted on the mounting plate 153 and the airbag 187;

[0101] Ring 186 is ring-shaped and hollow inside;

[0102] The airbag 187 has a ring-shaped cylindrical structure and is C-shaped and positioned outside the ring 186.

[0103] The connecting rod 188 is hollow inside and is fixed on the annular ring 186. The connecting rod 188 is located at the opening of the C-shaped airbag 187.

[0104] The C-shaped airbag 187 abuts against the connecting rod 188 at both ends;

[0105] The upper end of the connecting rod 188 is connected to the output end of the air pump 189, and the cavity of the connecting rod 188 is connected to the cavity of the annular ring 186.

[0106] Both the airbag 187 and the ring ring 186 have air supply ports 190, and the air supply ports 190 of the airbag 187 and the ring ring 186 are connected to each other.

[0107] The gas output by the air pump 189 enters the airbag 187 through the connecting rod 188, the annular ring 186 and the air supply port 190.

[0108] During filling, the airbag 187 is lifted by the buoyancy of the liquid, causing the mounting plate 153 and the liquid pipe 181 to rise in height.

[0109] Specifically, during the filling process, when the liquid tube 181 and hose 182 are inserted into the bottle, the air bladder 187, under the buoyancy of the filling liquid, drives the mounting plate 153, liquid tube 181, and hose 182 to continuously rise. During the rising process, the liquid tube 181 does not come into contact with the filling cleaning agent; only the lower hose 182 and the lower side of the air bladder 187 come into contact with the cleaning agent. This avoids excessive cleaning agent adhering to the tube, which would cause too much cleaning agent to be carried out when the liquid tube 181 and hose 182 are pulled out of the bottle, resulting in insufficient filling. It also avoids excessive cleaning agent being carried out and scattered outside the bottle, making cleaning difficult.

[0110] Furthermore, after the filling volume reaches the specified standard and filling stops, the air pump 189 is turned on to inflate the air bag 187, causing the air bag 187 to expand continuously. The expanded air bag 187 contracts inward, sealing the lower opening of the hose 182, preventing residual cleaning agent in the liquid tube 181 and hose 182 from being discharged during the upward process, thus improving the accuracy of the cleaning agent filling volume; and preventing residual cleaning agent inside the liquid tube 181 and hose 182 from dripping onto the outside of the bottle after being pulled out of the bottle, which would make cleaning difficult.

[0111] As the inflated airbag 187 rises in height, it can fit tightly against the bottle opening. During the ascent, some of the cleaning agent adhering to the surface of the airbag 187 is scraped off through the bottle opening, reducing the amount that drips out of the bottle and avoiding waste of cleaning agent.

[0112] The adjusting element 170 is installed on the mounting plate 153 and the liquid pipe 181. The adjusting element 170 is used to adjust the filling rate. When the height of the mounting plate 153 and the liquid pipe 181 is raised, the resistance of the adjusting element 170 increases, thereby reducing the filling rate.

[0113] The adjusting component 170 includes a connecting frame 171, a positioning plate 172, a lifting port 173, a sliding port 174, a conductive plate 176, a collar 177, and a resistance bar 178.

[0114] The connecting bracket 171 is fixed to one side of the positioning plate 172;

[0115] The lower side of the positioning plate 172 is two to three centimeters higher than the top of the bottle to be filled;

[0116] Specifically, the positioning plate 172 is higher than the bottle to be filled, which can prevent the bottle from hitting the positioning plate 172 during transportation, thus preventing transportation from being impossible.

[0117] The positioning plate 172 has a lifting port 173 and a sliding port 174.

[0118] The liquid pipe 181 is slidably disposed in the lifting port 173, and the connecting rod 188 is slidably disposed in the sliding port 174.

[0119] The conductive disk 176 is fixed on the positioning disk 172, the resistance strip 178 is fixed on the conductive disk 176, the collar 177 is slidably sleeved on the resistance strip 178, and the collar 177 is fixed on one side of the liquid tube 181.

[0120] The height adjustment component 150 also includes the sliding joint 156;

[0121] A sliding groove 156 is provided on the mounting plate 153, and the resistor strip 178 is slidably disposed in the sliding groove 156.

[0122] Specifically, since the collar 177 is fixed on one side of the liquid tube 181, as the height of the liquid tube 181 gradually increases, the height of the collar 177 on the resistor strip 178 also gradually increases. During the rising process, the circuit resistance between the conductive disk 176, the collar 177 and the resistor strip 178 gradually increases.

[0123] The upright plate 120 is fixed to one side of the base 110, and the conveyor belt 130 is positioned above the base 110;

[0124] Liquid pipe 181 is located directly above conveyor belt 130;

[0125] Specifically, the bottles to be filled are placed on the conveyor belt 130, and the bottles are transported to the bottom of the liquid pipe 181 by the conveyor belt 130.

[0126] The liquid supply unit 160 includes a liquid pump 161 and a flexible liquid supply tube 162;

[0127] The liquid pump 161 is fixed on one side of the vertical plate 120. The input end of the liquid pump 161 is connected to the liquid supply device. The two ends of the flexible liquid supply pipe 162 are fixed on the output end of the liquid pump 161 and the mounting plate 153, respectively. The flexible liquid supply pipe 162 passes through the mounting plate 153 and is connected to the liquid pipe 181.

[0128] The liquid pump 161 is connected to an external power supply. The negative terminal of the power supply is connected to the negative terminal of the liquid pump 161, and the positive terminal of the liquid pump 161 is electrically connected to the collar 177. The positive terminal of the power supply connected to the liquid pump 161 is electrically connected to the conductive disk 176.

[0129] The power supply connected to the liquid pump 161, the liquid pump 161, the conductive disk 176, the collar 177, and the resistor bar 178 together form a complete circuit loop.

[0130] When the liquid pipe 181 drives the collar 177 to gradually rise along the height of the resistor bar 178, the resistance increases and the power of the liquid pump 161 decreases.

[0131] Specifically, when the liquid pipe 181 drives the collar 177 to gradually rise along the height of the resistor bar 178, the circuit resistance between the power supply connected to the liquid pump 161, the liquid pump 161, the conductive plate 176, the collar 177 and the resistor bar 178 increases, thereby reducing the power of the liquid pump 161; as the level of the detergent in the bottle rises, the filling rate is automatically reduced to prevent overflow.

[0132] After the liquid pump 161 stops and stops delivering the cleaning agent, the air pump 189 immediately starts and expands the airbag 187 to seal the outlet of the hose 182.

[0133] There are two clamping parts 140, which are symmetrically arranged on the support of the conveyor belt 130;

[0134] Two clamping elements 140 are used to clamp the bottles to be filled;

[0135] The clamping component 140 includes a fixing frame 141, a telescopic rod 142, and a clamping plate 143;

[0136] The telescopic rod 142 is fixed at both ends to the fixed frame 141 and the clamping plate 143 respectively. The fixed frame 141 is fixed to the support of the conveyor belt 130. The clamping plate 143 has a groove on the side away from the telescopic rod 142.

[0137] One end of the connecting bracket 171 is fixed to the fixing bracket 141.

[0138] Specifically, after the conveyor belt 130 transports the bottle between the two clamping members 140, the telescopic rod 142 drives the clamping plate 143 to move toward the bottle. The position of the bottle is clamped and fixed by the two clamping plates 143 and the groove on one side of the clamping plate 143.

[0139] There are two connecting plates 152, which are symmetrically fixed on both sides of the mounting plate 153.

[0140] Connector plate 152 is made of iron;

[0141] The sliding sleeve 151 and the telescopic rod 154 correspond to the two connecting plates 152 respectively.

[0142] The sliding sleeve 151 is fixed on the base 110. The sliding sleeve 151 is located on one side of the conveyor belt 130. The output end of the sliding sleeve 151 is fixed below the connecting plate 152.

[0143] Specifically, the sliding sleeve 151 includes an outer sleeve and an inner sleeve, with the inner sleeve extending and retracting within the outer sleeve.

[0144] Telescopic rod 154 is fixed on base 110. Telescopic rod 154 is located on the side of conveyor belt 130 away from sliding sleeve 151. Electromagnet 155 is fixed at the upper end of telescopic rod 154.

[0145] Specifically, after the bottle is clamped and fixed in position by the clamping plate 143, the retraction of the telescopic rod 154 causes the mounting plate 153, liquid tube 181, hose 182, and airbag 187 to descend into the bottle. Then, the electromagnet 155 on the telescopic rod 154 is de-energized to prevent the telescopic rod 154 from affecting the height of the mounting plate 153 as the liquid level rises. During the filling process, the liquid level of the cleaning agent provides buoyancy to the airbag 187, mounting plate 153, liquid tube 181, and hose 182, causing them to gradually rise in height as the liquid level changes.

[0146] During the process of raising the height of the mounting plate 153, liquid pipe 181, and hose 182, the position is restricted by the sliding sleeve 151 so that it can rise vertically.

[0147] After one filling is completed, the telescopic rod 154 extends in length, and the auxiliary airbag 187, liquid tube 181 and hose 182 detach from the bottle to facilitate the next filling. When the telescopic rod 154, auxiliary airbag 187, mounting plate 153, liquid tube 181 and hose 182 need to be lowered for the next filling, the electromagnet 155 is energized and attracted to the connecting plate 152.

[0148] The two ends of the positioning rod 185 are fixed to the inner wall of the liquid pipe 181, and the upright rod 184 is fixed to the lower side of the positioning rod 185;

[0149] The flow distribution platform 183 is a frustum shape, and the upper side of the flow distribution platform 183 is fixed to the lower side of the upright 184.

[0150] The flow divider 183 is located below the hose 182;

[0151] The upper end of the positioning rod 185 is a pointed tip, and the cross-section of the positioning rod 185 is triangular. The upright rod 184 is cylindrical, and the diameter of the upright rod 184 is the same as the upper diameter of the flow divider 183.

[0152] Specifically, when the liquid passes through the distribution platform 183, the frustum-shaped distribution platform 183 changes the flow direction of the cleaning agent during filling, causing the cleaning agent to disperse in a ring around the perimeter, avoiding direct vertical impact on the bottom of the bottle and reducing air bubbles generated by the impact.

[0153] The sliding sleeve 151, conveyor belt 130, liquid pump 161, telescopic rod one 142, telescopic rod two 154, electromagnet 155, and resistance bar 178 are all existing technologies and will not be described in detail here.

[0154] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0155] During filling, the air bladder 187, buoyed by the liquid, causes the mounting plate 153, liquid tube 181, and hose 182 to rise with the liquid level. Only the lower part of the hose 182 and the air bladder 187 comes into contact with the cleaning agent, preventing a large area of ​​cleaning agent from adhering to the liquid tube 181. When pulled out, the air bladder 187 inflates and seals the hose 182, preventing residual cleaning agent from dripping and ensuring accurate filling volume. As the air bladder 187 rises, it comes into contact with the bottle mouth, scraping off any cleaning agent adhering to its surface, reducing waste and cleaning difficulties. A circuit is formed by the external power supply to the liquid pump 161, the liquid pump 161, the conductive plate 176, the collar 177, and the resistor strip 178. As the liquid level rises, the collar 177 moves along the resistor strip 178, increasing resistance and reducing the power of the liquid pump 161, thereby reducing the filling rate and preventing liquid overflow.

[0156] Example 2: In the above solution, the buoyancy of the airbag 187 drives the liquid pipe 181 and the hose 182 to rise, allowing for height adjustment. Simultaneously, the resistance short-circuited by the resistance bar 178 is adjusted during the rising height. However, during the filling process, the flow divider 183 alone cannot completely prevent the generation of air bubbles. These bubbles affect the accuracy of the airbag 187's rise, potentially causing the airbag 187 to be pressed against the air bubbles rather than against the liquid surface. Therefore, the solution in Example 1 is improved, such as... Figures 1-3 , Figures 10-12 As shown:

[0157] Adjusting component 170 also includes sliding port 175;

[0158] A second sliding opening 175 is made on the positioning plate 172;

[0159] It also includes a dispersion component 200, which includes an air supply pipe 210, an air blowing ring 220, an air hole 230, and an air pump 240;

[0160] The air ring 220 is annular and hollow inside. The air ring 220 is located on the outer ring of the airbag 187, and air holes 230 are opened on the outer ring of the air ring 220.

[0161] During filling, the lower side of the air blowing ring 220 and the upper side of the air bag 187 are on the same horizontal plane.

[0162] There are multiple pores 230, which are evenly spaced in a ring shape;

[0163] The air hole 230 is inclined to the filling liquid surface, and the air hole 230 forms an angle of 30-40 degrees with the filling liquid surface.

[0164] The air supply pipe 210 is fixed on the air blowing ring 220. The air supply pipe 210 is hollow inside and is connected to the air blowing ring 220.

[0165] The air supply pipe 210 is slidably installed in the sliding port 175. The upper end of the air supply pipe 210 is fixed on the mounting plate 153. The air pump 240 is fixed on the mounting plate 153. The output end of the air pump 240 is connected to the air supply pipe 210.

[0166] The airflow velocity from vent 230 is 0.5-1.5 m / s.

[0167] Specifically, the airflow velocity from the vent 230 is controlled at 0.5-1.5 m / s to avoid generating additional bubbles due to excessively fast airflow.

[0168] Specifically, during filling, the air ring 220 also enters the bottle. Through the operation of the air pump 240, air is supplied to the air supply pipe 210 and the air ring 220. The gas is discharged outward through the air hole 230. During the outward exhaust process, the air bubbles gathered around the air bag 187 are blown to the edge area to avoid the air bubbles from blocking the contact between the air bag 187 and the liquid surface, which would affect the accuracy of the buoyancy position of the air bag 187.

[0169] After filling is completed, air pump 240 stops blowing air.

[0170] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0171] Air is supplied to the air ring 220 by air pump 240, and the gas is discharged from the inclined air hole 230, blowing the air bubbles gathered around the air bag 187 to the edge, preventing air bubbles from adhering to the air bag 187 and affecting the accuracy of buoyancy. This ensures that the air bag 187 is in close contact with the liquid surface rather than air bubbles, making the liquid level detection more accurate, thereby improving the reliability of filling rate adjustment.

[0172] Example 3: During use, the above device uses the airbag 187 to block the hose 182 and provide buoyancy. However, after the airbag 187 and hose 182 are removed from the liquid surface, a large amount of cleaning agent remains attached to their surface. When the airbag 187 and hose 182 are pulled out of the bottle, the attached cleaning agent drips, causing waste and cleaning difficulties. Therefore, the solution in Example 1 is improved, such as... Figure 10 , Figure 13 As shown:

[0173] The two ends of the airbag 187 are fixed to the ring 186 in a ring shape;

[0174] The air supply port 190 is located at both ends of the airbag 187, which is fixed to the annular ring 186;

[0175] It also includes a reset rope 300;

[0176] The upper end of the reset rope 300 is fixed to the outer ring of the liquid tube 181, and the lower end of the reset rope 300 is fixed to the outer ring of the airbag 187.

[0177] There are multiple reset ropes 300, which are arranged in a ring with intervals.

[0178] The reset rope 300 is an elastic rope.

[0179] Specifically, after filling is completed and the airbag 187 inflates, it is pushed up by the telescopic rod 154, causing the liquid pipe 181, hose 182 and airbag 187 to rise in height. The airbag 187 touches the bottle mouth, and since only the two ends of the airbag 187 are fixed to the ring ring 186 in a ring shape, when the airbag 187 touches the bottle mouth and rises, the friction between the airbag 187 and the bottle mouth causes the other parts of the airbag 187 to rotate around the ring ring 186. During the rotation, the cleaning agent attached to the bottom of the airbag 187 and the outer wall and bottom of the hose 182 is squeezed, causing the cleaning agent to gather together and drip naturally.

[0180] Furthermore, when the airbag 187 is completely detached from the bottle opening, it returns to its original shape under the pull of its own elasticity and the elasticity of the reset rope 300, and generates vibration to drip the cleaning agent that has not yet dripped into the bottle.

[0181] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0182] The airbag 187 is fixed to the ring 186 at both ends. When pulled out, it rotates and rubs against the bottle opening, squeezing the attached cleaning agent, causing it to gather and drip back into the bottle. Under its own elasticity and the tension of the reset rope 300, the airbag 187 vibrates and deforms. Through rotation and vibration, the residual cleaning agent is recycled back into the bottle, preventing external dripping, reducing waste and subsequent cleaning work.

[0183] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
