Description

Technical Field

[0001] This invention belongs to the technical field of baby bottle cleaning machines, and specifically relates to a baby bottle cleaning machine. Background Technology

[0002] A baby bottle cleaning machine is a machine used for the automated cleaning of baby bottles. During cleaning, water is first introduced to remove residue, and then hot air is introduced to dry the bottles. In existing technology, the cleaning arm is propelled by the water pressure generated during spraying. This requires a high degree of precision in the fit between the rotating arm and the machine. High friction will affect the rotation of the arm, resulting in high requirements for the forming accuracy between the arm and the machine body. Insufficient water pressure will also affect the cleaning effect. Summary of the Invention

[0003] The purpose of this invention is to disclose a baby bottle cleaning machine to solve the technical problem that the spray arm of the existing baby bottle cleaning machine has poor cleaning effect when cleaning baby bottles.

[0004] To achieve the above objectives, the present invention discloses a baby bottle cleaning machine, comprising: The main unit chassis includes an installation box and a water tank, the water tank being used to hold cleaning fluid; A spraying mechanism is provided in the mounting box, and the spraying mechanism is provided with a main channel and spray nozzles that are connected to each other; The drying mechanism, located in the mounting box, includes an impeller, a conveyor body, and a heat source. The heat source is located in the conveyor body, the outlet of the impeller is connected to the conveyor body, and the conveyor body is connected to the main channel. A water supply mechanism is used to deliver the cleaning solution in the water tank to the impeller; A drive mechanism, connected to the impeller and the spray mechanism, drives the impeller to rotate, thereby enabling the flow of cleaning liquid and / or airflow into the main channel, and simultaneously drives the rotation of the spray mechanism.

[0005] As an optional implementation, the bottle washing machine further includes a drainage mechanism, which is movably configured relative to the conveyor body to adjust the opening size of the guide port connecting the conveyor body and the spray mechanism; Furthermore, the drainage mechanism has a water inlet that communicates with the inner cavity of the conveying body, and a drainage channel, so that when the spraying mechanism is not in operation, the water inlet can communicate with the inner cavity of the conveying body.

[0006] As an optional implementation, the drainage mechanism includes a telescopic drive and a sealing structure. The sealing structure is provided with the water inlet and the drainage channel. The telescopic drive is used to drive the sealing structure to perform telescopic movement in order to adjust the opening size of the guide port.

[0007] As an optional implementation, the sealing structure is inserted into the conveyor body from bottom to top, and performs telescopic movements in the vertical direction relative to the conveyor body and the spraying mechanism, respectively.

[0008] As an optional implementation, both the telescopic drive and the sealing structure extend vertically and are arranged side by side in the horizontal direction; The drainage mechanism includes a telescopic transmission assembly, which is arranged horizontally and connected to the telescopic drive member and the sealing structure, so that under the drive of the telescopic drive member, the telescopic transmission assembly can drive the sealing structure to perform telescopic movement in the vertical direction.

[0009] As an optional implementation, the telescopic transmission assembly includes a screw and a push rod. The screw is connected to the telescopic drive member and threadedly connected to the push rod. The push rod is connected to the sealing structure and extends horizontally to drive the sealing structure to perform telescopic movement in the vertical direction.

[0010] As an optional implementation, the main unit is provided with a partition, and the receiving cavity of the mounting box is divided into a cleaning space and an installation space by the partition. The drying mechanism, the water supply mechanism and the drive mechanism are located in the installation space, and the cleaning space is used to place baby bottles.

[0011] As an optional implementation, the partition is provided with a first connecting port and a first pair of interfaces, the impeller's suction port is provided corresponding to the first connecting port, and the water supply mechanism's drain port is provided corresponding to the first pair of interfaces.

[0012] As an optional implementation, the impeller includes an outer cover and blades disposed within the outer cover, the outer cover and the partition are integrally formed, and the outer cover is provided with a discharge port corresponding to the impeller.

[0013] As an optional implementation, the drive mechanism includes a rotary drive motor, a drive gear, a gear transmission assembly, and a driven gear. The output shaft of the rotary drive motor is connected to the impeller, and the gear transmission assembly is driven between the driven gear and the drive gear. The driven gear is connected to the spraying mechanism, and the spraying mechanism and the driven gear are detachably connected.

[0014] Compared with the prior art, the beneficial effects of the baby bottle washing machine of the present invention are as follows: The baby bottle washing machine of the present invention, by configuring the main unit to include an installation box and a water tank, allows for the installation of a spraying mechanism, a drying mechanism, a water supply mechanism, and a drive mechanism via the installation box. The water tank holds cleaning fluid. During the initial stage of bottle washing, the water supply mechanism delivers cleaning fluid to the impeller, and the rotation of the impeller propels the cleaning fluid towards the conveyor body. The fluid then flows into the main channel of the spraying mechanism and is sprayed out from the spray nozzles, achieving the effect of cleaning the baby bottles. After washing, when drying the baby bottles, the water supply mechanism stops, and the impeller drives airflow. This airflow, passing through a heat source, becomes hot air, which flows out through the main channel and spray nozzles to dry the baby bottles. Simultaneously, the rotation of the drive mechanism also drives the spraying mechanism to rotate, achieving both cleaning and drying of the baby bottles through rotation. Therefore, the baby bottle washing machine of this application also has the following beneficial effects: (1) When the drive mechanism drives the impeller, it also drives the spray mechanism to rotate synchronously. Thus, the spray mechanism achieves cleaning and drying of the baby bottle by being driven to rotate, which has higher cleaning efficiency and cleaning effect on the baby bottle. (2) One drive source can simultaneously drive the flow of air and cleaning liquid, and drive the rotation of the spray mechanism, thereby enabling the operation of multiple mechanisms and saving energy. (3) Only one drive source is set up, which saves the installation cost of the entire bottle cleaning machine and reduces the difficulty of maintenance when the machine fails later; (4) Only one drive source is set up, which occupies a small installation space, realizing the miniaturization of the entire bottle cleaning machine and making the entire machine structure more compact.

[0023] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0024] Please see Figures 1 to 18 This application provides a baby bottle cleaning machine 100, including a main unit 10, a spraying mechanism 20, a drying mechanism 30, a water supply mechanism 40, and a drive mechanism 50.

[0025] Please refer to Figures 1 to 9The main unit housing 10 includes a mounting box 11 and a water tank 12. The mounting box 11 has a receiving cavity 13 for holding the baby bottle 200. The water tank 12 is used to hold cleaning fluid, such as clean water or cleaning fluid with added detergent. A spraying mechanism 20 is located in the receiving cavity 13 of the mounting box 11. The spraying mechanism 20 has a main channel 21 and a spray nozzle 22 that are connected to each other. A drying mechanism 30 is located in the mounting box 11 and includes an impeller 31 and a conveyor. The impeller 31 has a body 32 and a heat source 33, which is located inside the body 32. The outlet 314 of the impeller 31 is connected to the body 32, and the body 32 is connected to the main channel 21. The water supply mechanism 40 is used to transport the cleaning liquid in the water tank 12 to the impeller 31. The drive mechanism 50 is connected to the impeller 31 and the spray mechanism 20 to drive the impeller 31 to rotate, thereby realizing the flow of cleaning liquid and / or airflow into the main channel 21, and simultaneously driving the rotation of the spray mechanism 20.

[0026] The aforementioned baby bottle washing machine 100, by setting the main unit 10 within a mounting box 11 and a water tank 12, allows the installation of a spray mechanism 20, a drying mechanism 30, a water supply mechanism 40, and a drive mechanism 50 via the mounting box 11. The water tank 12 holds cleaning fluid. During the initial cleaning of the baby bottles 200, the water supply mechanism 40 delivers cleaning fluid to the impeller 31, and the rotation of the impeller 31 propels the cleaning fluid towards the conveyor body 32. The cleaning fluid then flows into the main channel 21 of the spray mechanism 20 and is sprayed out from the spray nozzle 22. To achieve the effect of cleaning the baby bottle 200, after cleaning, when drying the baby bottle 200, the water supply mechanism 40 stops supplying water, and the impeller 31 drives the airflow. The airflow becomes hot air after passing through the heat source 33, and then flows out through the main channel 21 and the spray nozzle 22 to dry the baby bottle 200. At the same time, the rotation of the drive mechanism 50 can also drive the spray mechanism 20 to rotate, so as to achieve cleaning and drying of the baby bottle 200 by rotation. Therefore, the baby bottle washing machine 100 of this application also has the following beneficial effects: (1) When the drive mechanism 50 drives the impeller 31, it also drives the spray mechanism 20 to rotate synchronously. Thus, the spray mechanism 20 achieves cleaning and drying of the baby bottle 200 by being driven to rotate, which has higher cleaning efficiency and cleaning effect on the baby bottle 200. (2) One drive source can simultaneously drive the flow of air and cleaning liquid, and drive the rotation of the spray mechanism 20, thereby enabling the operation of multiple mechanisms and saving energy. (3) Only one drive source is set up, which saves the installation cost of the entire bottle washing machine by 100 and reduces the difficulty of maintenance when the machine fails later. (4) Only one drive source is set up, which occupies a small installation space, realizing the miniaturization of the entire bottle washing machine 100, and the entire machine structure is more compact.

[0027] In this example, when setting up the main unit box 10, the water tank 12 can be integrated with the installation box 11, or the water tank 12 can be detached from the installation box 11 to facilitate the removal and cleaning of the water tank 12 later.

[0028] Specifically, please refer to Figures 1 to 3 , Figure 10 as well as Figure 11 In this embodiment, the installation box 11 and the water tank 12 are integrated to facilitate the molding of the entire main unit box 10. In other embodiments, the water tank 12 can be detachably connected to the installation box 11, so that the water tank 12 can be removed separately for water filling or cleaning.

[0029] Further, please refer to Figures 2 to 11 To achieve waterproofing and protect the various mechanisms, the main unit housing 10 in this embodiment is equipped with a partition 17. The receiving cavity 13 of the mounting box 11 is divided into a cleaning space 131 and a mounting space 132 by the partition 17. The drying mechanism 30, the water supply mechanism 40, and the drive mechanism 50 are located in the mounting space 132, and the cleaning space 131 is used to place the baby bottle 200. The partition 17 has a first connecting port 171 that connects the cleaning space 131 and the mounting space 132. The suction port 311 of the impeller 31 is provided corresponding to the first connecting port 171, that is, through the main unit housing 10... The partition 17 is designed to house the drive mechanism 50, drying mechanism 30, and water supply mechanism 40 within the installation space 132. The area above the partition 17 contains the cleaning fluid, thus achieving a waterproof effect and preventing the cleaning fluid from damaging the drive mechanism 50 and other structures. The partition 17 is also provided with a first connecting port 171. When the cleaning fluid supplied by the water supply mechanism 40 flows onto the partition 17, a suction force is generated under the drive of the impeller 31, causing the cleaning fluid to flow towards the impeller 31. This allows the drive mechanism 50 to conveniently drive the cleaning fluid into the spray mechanism 20.

[0030] Understandably, in order to facilitate the installation of various mechanisms on the main unit 10, the main unit 10 may also include a bottom cover 15. An opening 16 is provided at the bottom of the mounting box 11, and the bottom cover 15 is placed over the opening 16. After the various mechanisms are installed in the mounting space 132, the bottom cover 15 is then placed on top, which facilitates the assembly of the entire machine.

[0031] It should be noted that in this embodiment, the water supply mechanism 40 delivers cleaning fluid to the suction port 311 of the impeller 31. This can be done by directly delivering the cleaning fluid to the suction port 311, for example, by aligning the drain port 41 of the drain pipe of the water supply mechanism 40 with the suction port 311; or by indirectly supplying water to the impeller 31. For example, in this embodiment, when the water supply mechanism 40 is supplying water, the drain port 41 of the water supply mechanism 40 is connected to the installation space 132. The cleaning fluid flows through the drain port 41 to the surface of the partition 17, first covering the surface of the partition 17, and then, driven by the impeller 31, the cleaning fluid sequentially passes through the inner cavity 321 and the main channel 21 of the conveying body 32, and finally sprays out from the spray port 22.

[0032] Specifically, the partition 17 is provided with a first pair of interfaces 172 corresponding to the drain outlet 41. The first pair of interfaces 172 are set to correspond to the drain outlet 41 of the water supply mechanism 40, and the partition 17 is provided with a first connecting port 171 corresponding to the suction port 311 of the impeller 31. In this way, by setting the first pair of interfaces 172 on the partition 17, the water supply mechanism 40 is facilitated, and it is not necessary to extend the pipe too long to align with the suction port 311 of the impeller 31. After the cleaning liquid flows out of the water supply mechanism 40, it flows onto the partition 17 and then flows towards the first connecting port 171. In other embodiments, the water outlet pipe 44 of the water supply mechanism 40 can be directly aligned with the suction port 311 of the impeller 31 as needed to supply water, thereby improving the water supply efficiency.

[0033] In this design, the impeller 31 is horizontally oriented, and the drive mechanism 50 is located below the impeller 31. Specifically, the partition 17 is a continuous plate. Thus, when the cleaning fluid flows from the surface of the partition 17, it can flow directly towards the impeller 31 under the suction force generated by the rotation of the impeller 31. Simultaneously, by oriented the impeller 31 horizontally (i.e., the central axis of the impeller 31 is vertical) and placing the drive mechanism 50 below the impeller 31, the installation space 132 is fully utilized, achieving miniaturization of the entire bottle washing machine 100. In other embodiments, the impeller 31 can be oriented in other directions, with the drain outlet 41 of the water supply mechanism 40 aligned with the suction inlet 311 of the impeller 31.

[0034] Furthermore, since the water tank 12 and the installation box 11 of this application are integrally set, the partition 17, the water tank 12 and one side wall of the installation box 11 in this embodiment form a liquid-containing cavity 121, thereby facilitating the setting of the liquid-containing cavity 121 through the setting of the partition 17; an opening 16 is formed at the bottom of the installation box 11, and after each mechanism is installed in the installation space 132, the bottom cover 15 is placed on the opening 16.

[0035] Please refer to Figure 2 , Figure 3 , Figure 10 and Figure 11 When installing the impeller 31, the impeller 31 includes an outer cover 312 and blades 313 disposed inside the outer cover 312. The outer cover 312 and the partition plate 17 are integrally formed, and the outer cover 312 is provided with a discharge port 314 corresponding to the impeller 31. In this way, by integrally forming the outer cover 312 and the partition plate 17, the space for installing the blades 313 can be formed when the entire main unit 10 is formed, avoiding the subsequent step of connecting the outer cover 312 of the impeller 31 to the partition plate 17, thus simplifying the assembly steps of the entire machine.

[0036] Please see Figure 2 , Figure 3 , Figure 12 and Figure 13 The diagram shows the structure of the water supply mechanism 40 in this embodiment of the invention, which includes a pump body 42, an inlet pipe 43 and an outlet pipe 44. The inlet pipe 43 is connected to the liquid chamber 121, and the outlet pipe 44 is connected to the first connecting port 171 (which can be directly connected or connected through an intermediate structure).

[0037] Further, please refer to Figure 2 , Figure 3 as well as Figure 11 When the water supply mechanism 40 is also installed below the partition 17, the water supply mechanism 40 also includes an inlet connector 45 and an outlet connector 46. Both the inlet connector 45 and the outlet connector 46 extend vertically. The inlet connector 45 is connected to the liquid-containing chamber 121, which is provided with a third pair of interfaces 19 and connected to the inlet pipe 43. The outlet connector 46 is connected to the first pair of interfaces 172 on the partition 17. In this way, the arrangement of the inlet connector 45 and the outlet connector 46 makes it easy to set the entire water supply mechanism 40 within the installation space 132, isolating the water vapor in the cleaning space 131 to protect the electronic components.

[0038] In this way, the pump body 42 draws out the cleaning liquid in the liquid chamber 121 and discharges it to the first pair of ports 172 onto the partition 17. The liquid flows on the partition 17 and towards the impeller 31. Under the suction action of the impeller 31, the liquid flows towards the conveyor 32, passes through the conveyor 32 and the spray mechanism 20 in sequence, and is sprayed out onto the spray nozzle 22, thereby cleaning the baby bottle 200.

[0039] Please see Figure 4 , Figure 6 , Figure 8 as well as Figures 12 to 15The diagram below shows the structure of the drying mechanism 30 according to an embodiment of the present invention. The drying mechanism 30 includes the impeller 31 (which drives the flow of cleaning agent and also drives the flow of air), a conveyor body 32 connected to the outlet 314 of the impeller 31, and a heat source 33 disposed in the conveyor body 32. The conveyor body 32 is connected to the spraying mechanism 20. Thus, when the impeller 31 rotates, it drives the airflow to flow into the conveyor body 32. Under the heating effect of the heat source 33, the cold airflow becomes hot airflow and is sprayed out from the spray nozzle 22. At the same time, under the drive of the drive mechanism 50, the spraying mechanism 20 rotates synchronously, and the hot airflow can be quickly diffused to achieve the effect of quickly drying the baby bottle 200.

[0040] Understandably, heat source 33 can also be turned on during the cleaning process to heat the cleaning agent. The high-temperature cleaning liquid comes into contact with the stains, improving cleaning efficiency.

[0041] Since the impeller 31 draws in fluid (gas or cleaning liquid) axially, and outputs the fluid radially, the bottle washing machine 100 in this embodiment also includes a docking structure 60 to facilitate the connection between the outlet 314 and the conveyor 32. For example... Figure 4 , Figure 6 , Figure 8 as well as Figure 11 As shown, the docking structure 60 is connected between the outlet 314 of the impeller 31 and the second pair of interfaces 322 of the conveyor body 32. In this way, by setting the docking structure 60, docking with the impeller 31 and the conveyor body 32 can be achieved. At the same time, the impeller 31 and the drive mechanism can be raised to reduce the height of the entire main unit 10 and achieve miniaturization of the whole machine.

[0042] Specifically, the docking structure 60 in this embodiment includes a first docking cylinder 61 and a second docking cylinder 62 arranged perpendicularly to each other. The first docking cylinder 61 is connected to the outlet 314 of the impeller 31, and the second docking cylinder 62 is connected to the second docking interface 322 of the conveying body 32. Further, to ensure docking between the second docking cylinder 62 and the conveying body 32, the docking structure 60 also includes a first sealing ring 63, such as... Figure 4 As shown, the first sealing ring 63 is sleeved on the outer wall of the second docking cylinder 62. In this way, the connection between the second docking cylinder 62 and the conveying body 32 is sealed by the first sealing ring 63, so as to avoid leakage of cleaning fluid or airflow.

[0043] Furthermore, to ensure the connection area between the second docking cylinder 62 and the conveyor body 32, a third docking cylinder 323 extends from the conveyor body 32 towards the second docking cylinder 62, such as... Figure 4 , Figure 14 and Figure 15As shown, the third docking cylinder 323 and the conveying body 32 are integrally formed. The second docking cylinder 62 drives the first sealing ring 63 to insert into the third docking cylinder 323, so that there is a sufficient contact area between the third docking cylinder 323 and the second docking cylinder 62, thereby improving the connection strength and sealing effect between them. In other embodiments, the third docking cylinder 323 can also be set inside the conveying body 32, which can also achieve the insertion and sealing effect between the second docking cylinder 62 and the third docking cylinder 323.

[0044] In this embodiment, the heat source 33 can be a PTC heating element or a graphene heating element, or other heating structures. Specifically, in this embodiment, the heat source 33 is set as a PTC heating element. To achieve waterproofing of the PTC heating element, it can be sealed with adhesive to prevent damage from contact with cleaning fluid. The PTC heating element is connected to fins, and heat exchange is achieved through the fins and the fluid.

[0045] In this design, the docking structure 60 can be integrally formed with the main unit housing 10. The conveyor body 32 can then be installed at the corresponding position on the docking structure 60, thus improving the overall forming efficiency of the bottle washing machine 100. Furthermore, the docking structure 60 also includes a sealing end cap 64, such as... Figure 6 , Figure 8 , Figure 12 and Figure 13 As shown, the sealing end cap 64 is located at the end of the first docking cylinder 61 away from the impeller to seal the end of the first docking cylinder 61.

[0046] Please see Figure 4 , Figure 6 , Figure 8 , Figure 12 and Figure 13 In order to improve the cleaning effect on the baby bottle 200, the baby bottle washing machine 100 of this embodiment also includes a shelf 70, which is used to support the baby bottle 200. The baby bottle 200 may include a bottle body 210 and a nipple 220, so that the bottle body 210 and the nipple 220 can be suspended in the air, for example, suspended in an upside-down manner, thereby improving the cleaning effect on the inner wall of the baby bottle 200.

[0047] Specifically, please refer to Figure 4 , Figure 6 and Figure 8The inner wall of the shelf 70 is provided with a connecting channel 71 that communicates with the flow channel of the spray mechanism 20. Thus, cleaning liquid or airflow from the spray mechanism 20 can flow out through the connecting channel 71 and impact the inner and outer walls of the bottle 210 and nipple 220, achieving a cleaning and drying effect. For example, a support arm 72 can be provided on the shelf 70 to support the bottle 210 and nipple 220, while also allowing cleaning liquid and airflow to flow out, thereby improving the cleaning and drying effects.

[0048] Please see Figure 4 , Figure 6 , Figure 8 as well as Figures 14 to 18 The diagram shows the structure of the spray mechanism 20 according to an embodiment of the present invention. It includes a detachably connected main shaft 23 and a spray arm 24. The main shaft 23 is arranged in the vertical direction and passes through the partition 17. One end is located above the partition 17. The spray arm 24 is connected to the end of the main shaft 23 located above the partition 17. The main shaft 23 is provided with a first sub-channel 211, and the spray arm 24 is provided with a second sub-channel 212. The first sub-channel 211 and the second sub-channel 212 are combined to form the main channel 21. The spray arm 24 is provided with a spray nozzle 22. The first sub-channel 211 is connected to the second sub-channel 212 and the inner cavity 321 of the conveyor body 32. The second sub-channel 212 is connected to the spray nozzle 22. The main shaft 23 is provided with a third connecting port 25 that is connected to the connecting channel 71 of the shelf 70. When the cleaning liquid and airflow flow through the main shaft 23, they can not only be discharged from the spray arm 24, but also flow onto the shelf 70 through the third connecting port 25. They can flow through the shelf 70 to impact the inner wall of the bottle 210 and the nipple 220, achieving a better cleaning and drying effect.

[0049] To improve the spraying effect, the spraying mechanism 20 in this embodiment includes two sets of spraying arms 24. The two sets of spraying arms 24 are separated in the axial direction of the main shaft 23. One set of spraying arms 24 is used to rinse and dry the outer surface of the bottle body 210 and the nipple 220 from top to bottom, and the other set of spraying arms 24 cleans and dries the inner wall of the bottle body 210 and the nipple 220 in an upward direction.

[0050] Please see Figure 12 Zhihe Figure 17The diagram below shows the structure of the drive mechanism 50 according to an embodiment of the present invention. The drive mechanism 50 includes a rotary drive motor 51, a drive gear 52, a transmission gear set 53, and a driven gear 54. The drive gear 52 is sleeved on the output shaft of the rotary drive motor 51, and the output shaft of the rotary drive motor 51 is connected to the impeller 31. The transmission gear set 53 is connected between the drive gear 52 and the driven gear 54. The driven gear 54 is connected to the spray mechanism 20, and the spray mechanism 20 and the driven gear 54 are detachably connected. Under the rotation of the rotary drive motor 51, not only can the cleaning liquid and / or airflow be driven, but the driving force is also transmitted to the spray mechanism 20 to drive the rotation of the spray mechanism 20, thereby achieving the cleaning and drying of the baby bottle 200 by rotation. At the same time, the detachable connection between the spray mechanism 20 and the driven gear 54 facilitates the assembly of the various parts. The spray mechanism 20 can be inserted into the driven gear 54 from the cleaning space 131.

[0051] In this embodiment, when connecting the driven gear 54 and the spray mechanism 20, the driven gear 54 can be sleeved on the outer wall of the main shaft 23 of the spray mechanism 20, so that when the driven gear 54 rotates, it can drive the main shaft 23 to rotate; alternatively, the driven gear 54 can be inserted into the cavity of the spray mechanism 20. Specifically, to facilitate the assembly and disassembly of the spray mechanism 20, in this embodiment, when the driven gear 54 and the main shaft 23 of the spray mechanism 20 are connected, the driven gear 54 extends into the main shaft 23 and engages with the main shaft 23.

[0052] Specifically, please refer to Figure 17 and Figure 18 The driven gear 54 includes an upper tooth portion 541 and a lower tooth portion 542. The outer diameter of the upper tooth portion 541 is smaller than the outer diameter of the lower tooth portion 542. The upper tooth portion 541 extends into the main shaft 23. The inner wall of the main shaft 23 is provided with a tooth portion 231. The upper tooth portion 541 and the tooth portion 231 mesh with each other. Thus, when the rotary drive motor 51 rotates, it can drive the spraying mechanism 20 to rotate.

[0053] Further, please refer to Figures 12 to 15 To prevent the driven gear 54 from being suspended, the bottle washing machine 100 of this embodiment also includes a support body 80. The support body 80 is connected and communicates between the conveyor body 32 and the main shaft 23. The support body 80 is used to install the driven gear 54 and to allow the driven gear 54 to rotate. The main shaft 23 is detachably inserted into the support body 80 and inserted outside the driven gear 54. Thus, when the spraying mechanism 20 needs to be installed, it can be inserted into the driven gear 54 from the side of the partition 17 facing the cleaning space 131. Thus, when assembling the bottle washing machine 100 of this application, after the various mechanisms in the installation space 132 are installed, the spraying mechanism 20 can be inserted and assembled from top to bottom.

[0054] Among them, such as Figures 4 to 9 As shown, when the main shaft 23 is installed with the support body 80 and the driven gear 54 respectively, the lower tooth 542 is supported by the support body 80. The drive mechanism 50 also includes a second sealing ring 55, which is sleeved on the outside of the main shaft 23. The upper tooth 541 of the driven gear 54 is provided with a first limiting wall 543 on the side facing the cleaning space 131. The main shaft 23 drives the second sealing ring 55 to be clamped between the first limiting wall 543 and the upper tooth 541. In this way, the rotation of the main shaft 23 driven by the driven gear 54 can be realized, and the seal between the main shaft 23 and the driven gear 54 can be realized at the same time, preventing liquid or gas from overflowing from the joint between the driven gear 54 and the main shaft 23, and also preventing liquid above the partition 17 from overflowing to the bottom.

[0055] Please see Figures 4 to 9 as well as Figure 14 and Figure 15 To accommodate the cylindrical structure of the main shaft 23, the conveyor body 32 of this application includes a mounting portion 324 and a docking portion 325. The mounting portion 324 mounts the heat source 33, and the docking portion 325 is cylindrical and passes through the support body 80. Furthermore, the docking portion 325 is adapted to the mounting height of the impeller 31, that is, to the height of the second docking cylinder 62.

[0056] To further achieve sealing between the support body 80 and the driven gear 54, the main shaft 23, and the docking part 325, a second limiting wall 544 is provided on the lower tooth part 542 in the direction of the support body 80. The drive mechanism 50 also includes a third sealing ring 56, which is sandwiched between the second limiting wall 544 and the docking part 325. Thus, when the cleaning fluid or airflow flows from the conveyor body 32 in the direction of the main shaft 23, the third sealing ring 56 prevents the cleaning fluid and airflow from leaking to the docking point between the docking part 325 and the driven gear 54.

[0057] In addition, please see Figures 4 to 9 Since the main shaft 23 needs to pass through the through hole 173 on the partition 17, in order to achieve a seal at the through hole 173, the partition 17 is provided with a limiting platform 18 at the through hole 173. The limiting platform 18 includes a vertical wall 181 and a horizontal wall 182. The horizontal wall 182 is connected to the vertical wall 181 and faces the first limiting wall 543, and abuts against the first limiting wall 543. The drive mechanism 50 also includes a fourth sealing ring 57. The fourth sealing ring 57 is sandwiched between the vertical wall 181, the horizontal wall 182 and the first limiting wall 543, and contacts the vertical wall 181, the horizontal wall 182 and the first limiting wall 543 respectively. In this way, the leakage of the cleaning fluid above the partition 17 is further restricted, and the seal between the installation space 132 and the cleaning space 131 is achieved.

[0058] In this embodiment, the mounting part 324, the docking part 325, and the support body 80 are integrated to facilitate the rapid prototyping of components in the entire machine.

[0059] Please see Figures 4 to 9 , Figure 12 , Figure 13 as well as Figure 19 In one embodiment of the present invention, after completing one cycle of cleaning the baby bottle 200, the dirty cleaning solution needs to be drained. The baby bottle cleaning machine 100 of this embodiment also includes a drainage mechanism 90, which is movably configured relative to the conveyor body 32 to adjust the opening size of the guide port 326 connecting the conveyor body 32 and the spray mechanism 20. Specifically, the adjusting docking part 325 is provided with the guide port 326. It should be noted that adjusting the opening size of the guide port 326 may include opening the guide port 326, closing the guide port 326, or only opening part of the guide port 326.

[0060] Specifically, the drainage mechanism 90 has an inlet 91 and a drainage channel 92 that communicate with the inner cavity 321 of the conveying body 32. When the spraying mechanism 20 is not in operation, the inlet 91 can communicate with the inner cavity 321 of the conveying body 32. Thus, when the drainage mechanism 90 opens the guide port 326, the guide port 326 can communicate with both the inner cavity 321 of the conveying body 32 and the main flow channel 21 in the main shaft 23, allowing cleaning liquid and airflow to flow from the conveying body 32 to the main shaft 23. When the drainage mechanism 90 is open, the drainage channel 90 can communicate with the inner cavity 321 of the conveying body 32 and the main flow channel 21 in the main shaft 23. When the water mechanism 90 closes or reduces the opening area of ​​the guide port 326, the water inlet 91 can connect with the inner cavity 321 of the conveyor body 32. The cleaning fluid in the inner cavity 321 of the conveyor body 32 can enter the drainage channel 92 through the water inlet 91 and be discharged through the drainage channel 92. Alternatively, when the water supply mechanism 40 and the impeller 31 are not supplying water, the cleaning fluid remaining in the main shaft 23 can flow down through the guide port 326 into the inner cavity 321 of the conveyor body 32 and be discharged through the drainage channel 92. Thus, after completing one cleaning drainage, cleaning fluid is introduced into the main shaft 23 for a second cleaning. By using multiple drainage and multiple water supply methods, a better cleaning effect can be achieved.

[0061] Specifically, please refer to Figure 19 The drainage mechanism 90 includes a telescopic drive 93 and a sealing structure 94. The sealing structure 94 has an inlet 91 and a drainage channel 92. The telescopic drive 93 drives the sealing structure 94 to telescopically move, thereby adjusting the opening size of the guide port 326. Thus, the sealing structure 94 opens and closes the guide port 326 by telescopically moving, for example, telescopically moving vertically. In other embodiments, the conveying body 32 can slide relative to the support body 80 and then extend into the upper toothed portion 541 to open and close the guide port 326.

[0062] Specifically, in this embodiment, the sealing structure 94 is inserted into the conveyor body 32 from bottom to top, and performs vertical extension and retraction movements relative to the conveyor body 32 and the spray mechanism 20, thereby allowing the sealing structure 94 to have a simpler structural configuration in a vertical extension and retraction manner.

[0063] Specifically, please refer to Figure 19 The telescopic drive member 93 and the sealing structure 94 extend vertically and are arranged side by side in the horizontal direction. The drainage mechanism 90 includes a telescopic transmission assembly 95, which is arranged horizontally and is connected between the telescopic drive member 93 and the sealing structure 94. Under the drive of the telescopic drive member 93, the telescopic transmission assembly 95 can drive the sealing structure 94 to move vertically. In this way, the telescopic transmission assembly 95 converts the vertical driving force of the telescopic drive member 93 into the vertical movement of the sealing structure 94, and enables the telescopic drive member 93 and the sealing structure 94 to be arranged side by side in the horizontal direction, avoiding the increase in the overall height of the machine caused by directly connecting them in the vertical direction.

[0064] Specifically, please refer to Figure 19 The telescopic transmission assembly 95 of this embodiment includes a screw 951 and a push rod 952. The screw 951 is connected to the telescopic drive member 93 and is threadedly connected to the push rod 952. The push rod 952 is connected to the sealing structure 94 and extends horizontally to drive the sealing structure 94 to move vertically. That is, the threaded connection between the screw 951 and the push rod 952 allows the push rod 952 to move vertically when the screw 951 rotates under the drive of the telescopic drive member 93, thereby driving the sealing structure 94 to move vertically.

[0065] Please see Figure 5 , Figure 7 , Figure 9 as well as Figure 19This is a schematic diagram of the sealing structure 94 according to an embodiment of the present invention. It includes a piston cylinder 941 and a first sealing sleeve 942 and a second sealing sleeve 943 disposed on the outer wall of the piston cylinder 941. The first sealing sleeve 942 is disposed at the end of the piston cylinder 941, and the second sealing sleeve 943 is sleeved on the outer wall of the piston cylinder 941. The first sealing sleeve 942 is used to adjust the opening size of the guide port 326. The second sealing sleeve 943 is used to cooperate with the conveying body 32. When the conveying body 32 and the main shaft 23 are connected, the second sealing sleeve 943 can seal the through hole of the piston cylinder 941 on the conveying body 32. When the conveying body 32 and the main shaft 23 are in the closed or closed part, the second sealing sleeve 943 can also seal the through hole of the piston cylinder 941 on the conveying body 32 to prevent cleaning liquid or airflow from leaking out from the through hole of the conveying body 32 and the piston cylinder 941. The area of ​​the piston cylinder 941 where the second sealing sleeve 943 is installed is provided with a water inlet 91.

[0066] The first sealing sleeve 942 can partially or completely close the guide port 326. The first sealing sleeve 942 includes a main body 9421 and a retaining ring 9422 disposed circumferentially around the outer periphery of the main body 9421. The main body 9421 extends into the docking part 325, and the outer diameter of the main body 9421 is smaller than the inner diameter of the docking part 325. When the retaining ring 9422 abuts against the port of the docking part 325, the guide port 326 is closed. When there is a gap between the retaining ring 9422 and the port of the docking part 325, the fluid can flow back from the main shaft 23 and be discharged through the piston cylinder 941, avoiding the situation where water remains in the main shaft 23 and causes bacterial growth after the docking part 325 is fully closed when the water supply is stopped. At the same time, when the heat source 33 is heating, the hot airflow can continue to flow into the main shaft 23 to dry the main shaft 23.

[0067] Please see Figure 5 and Figure 6 This is a schematic diagram of the fluid flow when the baby bottle washing machine 100 cleans the baby bottle 200 according to an embodiment of the present invention, or it can be a schematic diagram of the fluid flow when the spraying mechanism 20 is dried. At this time, the sealing structure 94 is open to the guide port 326, the first sealing sleeve 942 is disengaged from the end of the docking part 325, and the water inlet 91 and the inner cavity 321 of the conveying body 32 are blocked. The cleaning liquid or airflow flows from the first connecting port 171 through the impeller 31 towards the docking structure 60 and flows to the conveying body 32. The conveying body 32 flows to the main shaft 23, flows through the first sub-channel 211 and the second sub-channel 212 respectively, and finally is discharged from the spray port 22. Please see Figure 6 and Figure 7When a cycle of cleaning is completed, and the cleaning fluid in the cleaning space 131 needs to be drained, the sealing structure 94 moves upward, and the first sealing sleeve 942 is inserted into the docking part 325, blocking the connection between the guide port 326 and the inner cavity 321 of the conveying body 32. At this time, the water inlet 91 and the inner cavity 321 of the conveying body 32 are connected. The cleaning fluid on the partition 17 flows into the direction of the conveying body 32 under the drive of the impeller 31, and is finally discharged to the outside of the main unit box 10 through the water inlet 91, the drainage channel 92 and the drainage pipe 96. Please see Figure 8 and Figure 9 This is a schematic diagram of another drying state of the baby bottle washing machine 100. The main body 9421 extends into the docking part 325. There is a gap between the holding ring 9422 and the port of the docking part 325. At the same time, the water inlet 91 is also connected to the inner cavity 321 of the conveying body 32. Driven by the impeller 31, the heat source 33 is turned on, and the hot airflow can flow into the main shaft 23 and into the piston cylinder 941 to achieve the effect of drying the spray mechanism 20 and the sealing structure 94, thus preventing the growth of bacteria.

[0068] The aforementioned bottle washing machine 100, by setting a drainage mechanism 90, can drain dirty water after each washing cycle, and can clean and drain the bottles 200 in a multiple-cycle manner, improving the cleaning effect and preventing the cleaning liquid from remaining in the conveyor body 32 or the main shaft 23 and causing bacterial growth. By extending the telescopic drive component 93 and the sealing structure 94 in the drainage mechanism 90 vertically and connecting them through a horizontally set top rod 952, the vertical height of the entire machine can be reduced. By connecting the drive mechanism 50 to the spray mechanism 20, the rotation of the spray mechanism 20 can be driven synchronously, realizing the unified drive source of water inlet, air inlet and spraying, simplifying the structure of the entire bottle washing machine 100, facilitating miniaturization and subsequent maintenance. By setting a partition 17 in the main unit box 10, the cleaning space 131 and the installation space 132 can be blocked, preventing the cleaning liquid used to clean the bottles 200 from corroding the electrical components.

[0069] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
