[0002] In the beverage bottling industry, aseptic beverage filling technology has gradually become a focus of industry attention. One of the key aspects of aseptic filling is ensuring that the surface microbial content of bottle and cap packaging materials meets usage requirements after sterilization. Currently, bottle cap sterilization often involves spraying peracetic acid or hydrogen peroxide onto the caps. Commonly used spraying structures typically employ a nozzle to spray and rinse the caps in a single direction, resulting in ineffective sterilization of certain areas of the caps. This can lead to beverage contamination, affecting product quality and consumer health. Furthermore, after sterilization, insufficient drainage of the disinfectant from the nozzle can leave residue inside, causing scale buildup and bacterial growth. Utility Model Content

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] like Figures 1 to 10 As shown, a bottle cap disinfectant spraying device according to this embodiment includes a support assembly 100 and an infusion pipe 200. The support assembly 100 is provided with an inlet channel 101. The support assembly 100 includes a fixed base 110 and a connecting base 120 connected to the fixed base 110. The outer wall of the connecting base 120 is provided with a drain hole 121 communicating with the inlet channel 101. The connecting base 120 has a drain position. When the connecting base 120 is in the drain position, the drain hole 121 is vertically downward. The infusion pipe 200 is connected to the inlet channel 101. The length direction of the infusion pipe 200 extends along the conveying direction of the bottle cap 1. The infusion pipe 200 is provided with a plurality of first spray pipes 210 and a plurality of second spray pipes 220 at intervals along its length direction. The first spray pipes 210 face the inner wall of the bottle cap 1, and the second spray pipes 220 face the outer wall of the bottle cap 1.

[0036] In this embodiment, by connecting the infusion pipeline 200 to the support assembly 100, and by arranging a plurality of first spray nozzles 210 and a plurality of second spray nozzles 220 at intervals along the length of the infusion pipeline 200, disinfectant is sprayed towards the inner wall of the bottle cap 1 through the first spray nozzles 210 and towards the outer wall of the bottle cap 1 through the second spray nozzles 220, thereby achieving comprehensive sterilization and disinfection of the bottle cap 1 from multiple angles, greatly reducing the microbial content on the surface of the bottle cap 1, thereby preventing the growth of microorganisms in the beverage and ensuring the hygiene of the beverage. Furthermore, a drain hole 121 is provided on the connecting seat 120. After the spraying disinfection operation of the bottle cap 1 is completed, the connecting seat 120 is moved relative to the fixed seat 110 so that the connecting seat 120 is in the drain position. At this time, the drain hole 121 on the connecting seat 120 is set vertically downward, which is conducive to the discharge of the disinfectant remaining in the infusion pipeline 200 through the drain hole 121, avoiding the presence of disinfectant residue in the infusion pipeline 200, and thus preventing scale buildup and bacterial growth inside the infusion pipeline 200.

[0037] In actual operation, when spraying disinfectant, the drain hole 121 is sealed with a rubber plug or similar component to prevent the disinfectant from being discharged directly from the drain hole 121 during the flow of disinfectant from the inlet channel 101 to the delivery pipeline 200, thus avoiding waste and pollution. When it is necessary to drain the residual disinfectant, the rubber plug is removed, allowing the residual disinfectant to be discharged smoothly from the drain hole 121.

[0038] Furthermore, when the connecting seat 120 is in the drain position, the lower inner wall of the infusion pipe 200 is set at an angle to the horizontal plane, and the horizontal height of the lower inner wall gradually increases in the direction away from the drain hole 121, so that the disinfectant remaining in the infusion pipe 200 flows towards the drain hole 121 along the end away from the drain hole 121 under the action of gravity, so that the disinfectant in the infusion pipe 200 is completely drained, ensuring that there is no disinfectant residue in the infusion pipe 200.

[0039] Furthermore, the inner diameter of the infusion pipe 200 gradually decreases in the direction away from the support component 100. This is because the flow rate of the disinfectant gradually decreases after it is input from the inlet channel 101 of the support component 100. In this embodiment, by setting the inner diameter of the infusion pipe 200 to gradually decrease in the direction away from the support component 100, the flow rate of the disinfectant in the infusion channel remains basically the same. This ensures that the spray pressure of each first nozzle 210 and second nozzle 220 along the delivery path of the bottle cap 1 is basically the same, ensuring that the disinfectant sprayed by the first nozzle 210 and second nozzle 220 can effectively cover the corresponding area of ​​the bottle cap 1, and that the first nozzle 210 and second nozzle 220 at both ends maintain the same intensity of rinsing effect on the bottle cap 1, thus ensuring the overall disinfection effect of the bottle cap 1.

[0040] In one embodiment, one end of the fixing base 110 is provided with a slot 111 for the connector 2 of the external infusion device to be inserted, and the other end of the fixing base 110 is connected to the infusion pipeline 200. The outer side wall of the connector 2 is provided with a first sealing groove 21, and a first sealing ring 22 is provided in the first sealing groove 21. The first sealing ring 22 abuts against the groove wall of the first sealing groove 21 and the groove wall of the slot 111 respectively to ensure the sealing between the fixing base 110 and the connector 2 and to prevent the disinfectant from leaking.

[0041] In one embodiment, one end of the connecting seat 120 is rotatably connected to the fixed seat 110 about a first axis 310, and the other end of the connecting seat 120 is rotatably connected to the infusion pipeline 200 about a second axis 320. The second axis 320 is the central axis of the infusion pipeline 200, and the first axis 310 and the second axis 320 are parallel to each other. That is, the infusion pipeline 200 rotates relative to the fixed seat 110 about the first axis 310, and the horizontal height of the infusion pipeline 200 is adjusted during the rotation of the infusion pipeline 200 relative to the fixed seat 110 about the first axis 310 to adapt to the delivery height of different bottle caps 1.

[0042] Specifically, after rotating the connecting seat 120 to position the infusion pipeline 200 at a predetermined horizontal height, the connecting seat 120 is fixed to the fixed seat 110 using fasteners such as set screws 400. Then, the infusion pipeline 200 is rotated to position the first nozzle 210 and the second nozzle 220 at predetermined positions, and the infusion pipeline 200 is fixed to the connecting seat 120 using fasteners such as set screws 400. This allows for the adjustment of the height of the infusion pipeline 200 and the angle adjustment of the first nozzle 210 and the second nozzle 220, thus adapting to different working conditions and exhibiting strong versatility.

[0043] In addition, the drain hole 121 is provided on the connecting seat 120. When it is necessary to drain the disinfectant, the connecting seat 120 is rotated so that the drain hole 121 is vertically downward, that is, the overall support assembly 100 is located at the above-mentioned drain position.

[0044] In actual operation, a second sealing groove 122 is provided on the outer wall of the side where the connecting seat 120 connects to the fixed seat 110. A second sealing ring 123 is provided inside the second sealing groove 122. The second sealing ring 123 abuts against the groove wall of the second sealing groove 122 and the inner wall of the fixed seat 110 to ensure the sealing of the connecting seat 120 and the fixed seat 110 and prevent disinfectant leakage. Similarly, a third sealing groove 230 is provided on the outer wall of the side where the infusion pipeline 200 connects to the connecting seat 120. A third sealing ring 240 is provided inside the third sealing groove 230. The third sealing ring 240 abuts against the groove wall of the third sealing groove 230 and the inner wall of the fixed seat 110 to ensure the sealing of the infusion pipeline 200 and the connecting seat 120 and prevent disinfectant leakage. The second sealing ring 123 and the third sealing ring 240 can effectively prevent leakage during the rotation of the connecting seat 120 and the infusion pipeline 200.

[0045] In one embodiment, multiple first spray nozzles 210 are provided, with the spraying directions of adjacent first spray nozzles 210 forming an angle, so as to enable comprehensive disinfection of the bottle cap 1 from multiple angles. Furthermore, the spraying direction of each first spray nozzle 210 is also set at an angle to the horizontal plane, so that the disinfectant sprayed by the first spray nozzle 210 also forms an angle with the inner wall of the bottle cap 1, which helps to improve the rinsing effect of the disinfectant on microorganisms, i.e., dust, on the inner wall of the bottle cap 1.

[0046] In one embodiment, such as Figure 3 As shown, taking the first nozzle 210 as an example, the first nozzle 210 includes a first main body 211 and a first connecting pipe 212. The outer diameter of the first main body 211 is larger than the outer diameter of the first connecting pipe 212. A first stepped surface 213 is formed at the connection between the first main body 211 and the first connecting pipe 212. A connecting hole 250 is provided on the side wall of the infusion pipeline 200 for inserting the first connecting pipe 212, which facilitates the positioning of the first nozzle 210. When the first connecting pipe 212 is inserted into the connecting hole 250, the first stepped surface 213 abuts against the outer side wall of the infusion pipeline 200, which facilitates welding. Similarly, the connection method between the second nozzle 220 and the infusion pipeline 200 is the same as that between the first nozzle 210 and the infusion pipeline 200.

[0047] In other embodiments, other connection methods may also be used, such as Figure 10As shown, taking the second nozzle 220 as an example, the infusion pipeline 200 is provided with a connecting groove 260 for the second nozzle 220 to be inserted into. The connecting groove 260 has a second stepped surface 261. The second nozzle 220 is inserted into the connecting groove 260, and the end face of one end of the second nozzle 220 abuts against the second stepped surface 261 to facilitate positioning and welding of the second nozzle 220. In this embodiment, the first nozzle 210 also adopts the same connection method. Of course, in actual operation, the first nozzle 210 and the second nozzle 220 can each adopt different connection methods, or other connection methods, as long as they ensure a stable connection between the first nozzle 210 and the second nozzle 220 and the infusion pipeline 200. Such methods are all within the protection scope of this utility model.

[0048] In one embodiment, multiple second spray nozzles 220 are provided, with two second spray nozzles 220 forming a group. The two second spray nozzles 220 in each group are symmetrically arranged relative to the conveying path of the bottle cap 1 to spray disinfectant onto both sides of the bottle cap 1 along the conveying path, ensuring thorough disinfection. The spray direction of the second spray nozzles 220 is set at an angle to the horizontal plane, which helps to improve the rinsing effect of the disinfectant on microorganisms, i.e., dust, on the outer wall of the bottle cap 1.

[0049] In one embodiment, the first nozzle 214 of the first nozzle 210 is provided with a first nozzle orifice 2141, and the second nozzle 221 of the second nozzle 220 is provided with a second nozzle orifice 2211. The inner diameter of the first nozzle orifice 2141 and the second nozzle orifice 2211 is d, and the inner diameter of the first nozzle 210 and the second nozzle 220 is D, where D ≥ 2d. Figure 3 As shown, taking the first nozzle 20 as an example, the inner diameter D of the first nozzle 210 is set to be greater than or equal to twice the inner diameter d of the first nozzle 2141, so that the disinfectant has sufficient impact force when it is ejected from the first nozzle 2141 of the first nozzle 214, so as to effectively rinse the dust and other impurities on the bottle cap 1 and improve the cleaning effect of the bottle cap 1.

[0050] In one embodiment, the support assembly 100 further includes a support base 130 and a locking member 140. The support base 130 has a support groove 131 for placing the infusion tubing 200. The infusion tubing 200 is placed in the support groove 131. The side wall of the support base 130 has a locking hole 132 communicating with the support groove 131. The locking member 140 passes through the locking hole 132 and presses the infusion tubing 200 against the support groove 131. The open support groove 131 structure makes the installation and removal of the infusion tubing 200 more convenient. In addition, when adjusting the horizontal height of the infusion tubing 200, the support base 130 of the corresponding height can be replaced to adapt to the horizontal height support and installation of the infusion tubing 200, making the operation flexible. In actual operation, the locking hole 132 is a threaded hole, and the locking member 140 is a bolt. The infusion tubing 200 is pressed against the support groove 131 by screwing the bolt into the locking hole 132.

[0051] In one embodiment, two sets of infusion tubing 200 are provided, and the two sets of infusion tubing 200 are connected by a connecting assembly 500. The connecting assembly 500 includes a connecting sleeve 510, a first fixing member 520, and a second fixing member 530. The connecting sleeve 510 has a connecting through hole for the infusion tubing 200 to pass through. The outer wall of the connecting sleeve 510 also has a first fixing hole 511 and a second fixing hole 512 respectively communicating with the connecting through hole. The first fixing member 520 passes through the first fixing hole 511 and abuts one of the infusion tubing 200 inserted into the connecting through hole. The second fixing member 530 passes through the second fixing hole 512 and abuts the other infusion tubing 200 inserted into the connecting through hole, thereby ensuring that the connecting sleeve 510 is securely installed with the two sets of infusion tubing 200 respectively. This embodiment adopts a segmented infusion tubing 200 structure, which facilitates installation, disassembly, and maintenance operations. In actual operation, the first fixing member 520 and the second fixing member 530 can adopt fixing member structures such as screws or bolts, which are simple to obtain and easy to install and disassemble.

[0052] Furthermore, two fourth sealing grooves 513 are respectively provided on the inner side wall of the connecting sleeve 510 and the two sides of the infusion pipeline 200. Each fourth sealing groove 513 is provided with a corresponding fourth sealing ring 514. The fourth sealing rings 514 abut against the groove wall of the fourth sealing groove 513 and the outer side wall of the infusion pipeline 200 to ensure the sealing between the connecting sleeve 510 and the infusion pipeline 200 and prevent the disinfectant from leaking.

[0053] In one embodiment, two sets of support components 100 are provided, each set located at one end of the infusion pipeline 200, and each set of support components 100 is connected to one set of infusion pipelines 200. The drain holes 121 of the two sets of support components 100 are staggered along the axial direction surrounding the infusion pipeline 200. Specifically, during the residual disinfectant draining operation, one set of support components 100 is first adjusted to its corresponding draining position, and the residual disinfectant in the infusion pipeline 200 connected to it is drained using the drain holes 121 of this set of support components 100. Then, the other set of support components 100 is adjusted to its corresponding draining position, and the residual disinfectant in the infusion pipeline 200 connected to it is drained using the drain holes 121 of this set of support components 100. Furthermore, during the position adjustment process of the two sets of support components 100, the infusion pipeline 200 is driven to move (rotate or shake), so that the residual disinfectant in the infusion pipeline 200 generates kinetic energy and flows along the infusion pipeline 200 to the drain hole 121, which is conducive to the discharge of residual disinfectant.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
