Description

Technical Field

[0001] The invention belongs to the technical field of packaging bottles, in particular to an air bag type pump head and a packaging bottle thereof. Background Art

[0002] A packaging bottle is a packaging container in the packaging industry, which is widely used to hold various items such as beverages, medicines and cosmetics.

[0003] The bladder pump head packaging bottle is a special packaging container, which consists of a bottle body, a pump head and an air bag. The bottle body is used to hold liquid products, and the pump head is responsible for the extrusion and distribution of the liquid. The bladder pump head is the core part of the packaging bottle. When the pump head is pressed, the pressure inside the pump body changes, and the piston moves downward to form a negative pressure, so that the liquid is sucked into the pump body. By repeatedly pressing and releasing the pump head, the liquid in the pump body is continuously sucked in and ejected, forming a stable liquid flow.

[0004] The liquid is squeezed out through the pump head for use, but after use, some liquid will remain at the end of the pump head. These residual liquids will form solid residues after drying, which can easily clog the pump head and cause waste of liquid.

[0005] To this end, the present invention provides an air bag type pump head and a packaging bottle thereof. Summary of the invention

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] like Figures 1 to 5 As shown, an air bag type pump head according to an embodiment of the present invention comprises a lock cover 10; a main column 11 is provided on the top of the lock cover 10; a pressing head 12 is installed in the middle of the main column 11; a sub-column 13 is provided at the bottom of the lock cover 10; a suction tube 14 is installed in the middle of the sub-column 13; a filter assembly 2 is provided at the end of the suction tube 14; a cleaning assembly 3 is provided in the middle of the suction tube 14; two fixing blocks 15 are fixedly connected to the inner side wall of the pressing head 12; the two fixing blocks 15 are arranged opposite to each other; a sliding rod 16 is slidably connected to the middle of the fixing block 15; the ends of the two sliding rods 16 are fixed A baffle 18 is connected; a first spring 17 is fixedly connected to the side wall of the fixing block 15 and the middle of the baffle 18; a scraper 19 is fixedly connected to the side wall of the baffle 18; during operation, after the liquid is loaded into the bottle, the lock cover 10 is installed on the top of the bottle, the auxiliary column 13 and the straw 14 enter the bottle, and the lock cover 10 is rotated and fixed to the top of the bottle. When the liquid in the bottle is used, the top of the pressing head 12 is pressed, and the air in the airbag is compressed, and the liquid is sucked from the end of the straw 14 through the driving part and the conveying part inside the auxiliary column 13. By adjusting the control valve internally, the liquid in the bottle is continuously transported. When the liquid is discharged from the end of the pressing head 12, the liquid applies pressure to the baffle 18 to push it outward. As the baffle 18 moves, the slide bar 16 slides in the middle of the fixed block 15, and the first spring 17 generates elastic stretching, so that the baffle 18 moves out from the end of the pressing head 12, and the liquid flows out from the end of the pressing head 12. At the end, the baffle 18 rebounds into the inside of the pressing head 12 through the first spring 17, and the liquid residue at the end of the pressing head 12 and the inner wall is scraped and cleaned by the scraper 19. The above structure can reduce the residue generated when the liquid is discharged from the end of the pressing head 12, effectively reduce the deterioration or pollution caused by the residual liquid staying at the end of the pressing head 12, reduce the corrosion and wear of the end of the pressing head 12 due to the residual liquid, effectively maintain the cleanliness of the end of the pressing head 12, and make the liquid remaining at the end of the pressing head 12 be scraped back into the inside of the pressing head 12, effectively reduce the solidification and waste of the liquid outside for a long time.

[0027] like Figure 2 and Figure 4 As shown, the filter assembly 2 includes a filter head 21; the filter head 21 is installed at the end of the straw 14; the inner wall of the filter head 21 is provided with a threaded groove 22; the end of the filter head 21 is fixedly connected with a filter screen 23; when working, the filter head 21 is first installed at the end of the straw 14, and the filter head 21 is fixed to the end of the straw 14 through the threaded groove 22. When the liquid flows and is discharged, the sediment in the liquid is first filtered through the filter screen 23. The above structure can effectively filter out impurities and sediment particles in the liquid to maintain the quality of the output liquid. At the same time, the filter head 21 can be quickly installed at the end of the straw 14, which can effectively make its disassembly and installation simple and quick, and is convenient for subsequent removal and cleaning.

[0028] like Figure 4As shown, the cleaning assembly 3 includes two sliding grooves 31; the two sliding grooves 31 are opened on the inner wall of the suction tube 14; the two sliding grooves 31 are arranged opposite to each other; a sliding block 32 is slidably connected to the middle of the sliding groove 31; a fixing ring 33 is fixedly connected to the middle of the two sliding blocks 32; a plurality of brush plates 34 are fixedly connected to the middle of the fixing ring 33; a second spring 35 is fixedly connected to the bottom of the sliding block 32; the other end of the second spring 35 is fixedly connected to the end of the sliding groove 31; when working, when the liquid is discharged through the driving component and is transported by compressed air, the brush plate 34 and the fixing ring 33 are pushed to make the sliding block 32 slide in the middle of the sliding groove 31, and at the same time, the second spring 35 generates elastic stretching, and the brush plate 34 Away from the filter screen 23, when the liquid stops being discharged without pressure, the fixing ring 33 and the brush plate 34 are reset to the position of the filter screen 23 by the second spring 35. At this time, the brush plate 34 passes through the middle of the filter screen 23 to clean the impurities and sediments attached to the filter screen 23 from the surface of the filter screen 23. The above structure can effectively reduce the accumulation of impurities in the middle of the filter screen 23 due to long-term use of the filter screen 23, so that the liquid can continue to pass through the filter screen 23 smoothly. The brush plate 34 can continuously enter the middle of the filter screen 23 when the liquid is discharged, so that the filter screen 23 remains unobstructed, effectively reducing the damage of the packaging bottle caused by clogging caused by impurities accumulated in the middle of the filter screen 23.

[0029] like Figures 1 to 3 As shown, a fixed cylinder 4 is fixedly connected to the top of the pressing head 12; a positioning rod 41 is slidably connected to the middle of the fixed cylinder 4; the end of the positioning rod 41 is fixedly connected to the top of the main column 11; during operation, when the top of the pressing head 12 is pressed, the fixed cylinder 4 moves downward with the pressing head 12 at the same time. At this time, the fixed cylinder 4 slides in the middle of the positioning rod 41 to position the pressing head 12 when it moves up and down, and the pressing head 12 is evenly pressed by the fixed cylinder 4 and the positioning rod 41. The above structure can provide guidance and support for the pressing head 12, so that the pressing head 12 remains stable during the pressing process, effectively reducing the shaking of the pressing head 12 during the pressing process, and can evenly distribute the pressing force to each part between the pressing head 12 and the main column 11, reducing the jamming and increased friction caused by uneven pressure due to shaking.

[0030] like Figure 3 As shown, a buffer ring 5 is fixedly connected to the end of the fixed cylinder 4; the buffer ring 5 is fixedly connected to the outside of the positioning rod 41; during operation, when the pressing head 12 is pressed downward, the buffer ring 5 moves with the end of the fixed cylinder 4, and when the pressing head 12 is pressed to the bottom, the end of the buffer ring 5 contacts the main column 11, and the buffer ring 5 absorbs the impact force and pressure during the downward movement of the pressing head 12. The above structure can effectively disperse the pressure during the pressing process of the pressing head 12, effectively absorb the impact force during the pressing process of the pressing head 12, reduce the friction between the pressing head 12 and the main column 11, and reduce the wear and damage caused by long-term friction.

[0031] like Figure 2 and Figure 4 As shown, a sealing gasket 6 is fixedly connected to the middle of the locking cover 10; the end of the sealing gasket 6 is arranged as an inclined surface; the sealing gasket 6 is fixedly connected between the locking cover 10 and the bottle; when working, when the locking cover 10 is installed on the top of the bottle, the sealing gasket 6 is tightly fitted with the inner wall of the bottle, and the bottle and the locking cover 10 are sealed by the sealing gasket 6 to prevent the liquid from entering the gap between the locking cover 10 and the bottle. The above structure can effectively reduce the leakage of the liquid inside the bottle through the gap when the pump head is working or during storage, effectively maintain good sealing, reduce waste and environmental pollution caused by leakage, and increase the friction between the pressing head 12 and the bottle, so that the pressing head 12 is more stable in a closed state.

[0032] like Figure 1 As shown, a packaging bottle comprises a bottle body 1 ; the packaging bottle is suitable for any one of the above-mentioned air bag type pump heads, and the locking cover 10 is installed on the top of the bottle body 1 .

[0033] like Figure 1 As shown, the side wall of the bottle body 1 is fixedly connected with a gripping pad 7; the gripping pad 7 is fixedly connected to the outer side wall of the bottle body 1; during work, when the packaging bottle is picked up, the hand is in close contact with the surface of the gripping pad 7, thereby increasing the friction between the bottle body 1 and the hand. The above structure can effectively fit the shape of the hand, provide a comfortable gripping feeling, and enable the packaging bottle to remain stable during the gripping process, thereby reducing the risk of the packaging bottle slipping due to a smooth surface and reducing the problem of damage to the pump head due to slipping.

[0034] During operation, after the liquid is loaded into the bottle, the lock cover 10 is installed on the top of the bottle, the auxiliary column 13 and the straw 14 enter the bottle, and the lock cover 10 is rotated to be fixed on the top of the bottle. When the liquid in the bottle is used, the top of the pressing head 12 is pressed, and the air in the airbag is compressed, and the liquid is sucked from the end of the straw 14 through the driving part and the conveying part inside the auxiliary column 13. The liquid in the bottle is continuously conveyed by adjusting the control valve inside. When the liquid is discharged from the end of the pressing head 12, the liquid presses the baffle 18 to push it outward. As the baffle 18 moves, the slide bar 16 slides in the middle of the fixed block 15, and the first spring The spring 17 generates elastic stretching, so that the baffle 18 moves out from the end of the pressing head 12, and the liquid flows out from the end of the pressing head 12. At the end, the baffle 18 rebounds into the inside of the pressing head 12 through the first spring 17, and at the same time, the scraper 19 scrapes and cleans the liquid residue on the end of the pressing head 12 and the inner wall. First, the filter head 21 is installed at the end of the straw 14, and the filter head 21 is fixed to the end of the straw 14 through the threaded groove 22. When the liquid flows and is discharged, the sediment in the liquid is first filtered through the filter screen 23. When the liquid is discharged through the driving component, it is transported by compressed air, pushing the brush plate 34 and the fixing ring 33 The sliding block 32 slides in the middle of the sliding groove 31, and the second spring 35 generates elastic stretching at the same time, and the brush plate 34 moves away from the filter screen 23. When the liquid stops being discharged without pressure, the fixing ring 33 and the brush plate 34 are reset to the position of the filter screen 23 by the second spring 35. At this time, the brush plate 34 passes through the middle of the filter screen 23 to clean the impurities and sediments attached to the filter screen 23 from the surface of the filter screen 23. When the top of the pressing head 12 is pressed, the fixed cylinder 4 moves downward with the pressing head 12 at the same time. At this time, the fixed cylinder 4 slides in the middle of the positioning rod 41 to position the pressing head 12 when it moves up and down. The pressure head 12 is evenly pressed when it is pressed. When the pressure head 12 is pressed downward, the buffer ring 5 moves with the end of the fixed tube 4. When the pressure head 12 is pressed to the bottom, the end of the buffer ring 5 contacts the main column 11. The buffer ring 5 absorbs the impact force and pressure during the downward movement of the pressure head 12. When the lock cover 10 is installed on the top of the bottle body 1, the sealing gasket 6 fits tightly against the inner wall of the bottle body 1. The sealing gasket 6 seals the bottle body 1 and the lock cover 10 to prevent liquid from entering the gap between the lock cover 10 and the bottle body 1. When taking the packaging bottle, the hand is in close contact with the surface of the gripping pad 7 to increase the friction between the bottle body 1 and the hand.
