Description

Technical Field

[0001] This utility model relates to the field of powder batching technology, and in particular to a height adjustment mechanism and a quantitative feeding device. Background Technology

[0002] As infants and toddlers grow, their nutritional needs, especially their intake of formula, change, directly leading to an increase in the size of the bottles needed to prepare formula. In recent years, with the promotion of the national multi-child policy, the number of families with multiple children has increased significantly, undoubtedly posing greater challenges to parents and other caregivers. They not only have to handle heavy housework but also constantly monitor and meet the various needs of their children, especially ensuring they don't go hungry. As formula is the primary source of nutrition for infants and toddlers, the efficiency and convenience of its preparation method are particularly important.

[0003] However, most existing formula preparation methods or machines rely on manual operation, such as measuring formula powder, adjusting water temperature, and shaking the bottle. These steps are not only cumbersome but also particularly inconvenient when a child urgently needs comforting and feeding. Especially in families with multiple children, the required bottle height and amount of formula will vary depending on the children's age. This requires caregivers not only to quickly prepare formula but also to prepare multiple bottles of different heights and adjust the formula dispenser to meet the varying needs. This multitasking undoubtedly increases the caregiver's burden and reduces feeding efficiency. To address these issues, we provide a height adjustment mechanism and a quantitative dispensing device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] like Figure 1 — Figure 6 The example shown.

[0038] This application provides a height adjustment mechanism, which includes at least one guide 100, a first rack 200, a movable frame 300, a first rotary drive 400, and a gear assembly 500.

[0039] In some embodiments, the guide member 100 is fixedly mounted on the base, the first rack 200 is fixedly mounted on the guide member 100, the movable frame 300 is slidably mounted on the guide member 100 along a first preset direction, the first rotary drive member 400 is fixedly mounted on the movable frame 300, the gear assembly 500 is mounted on the movable frame 300, the gear assembly 500 is connected to the movable frame 300 in a transmission connection, and the gear assembly 500 meshes with the first rack 200.

[0040] See Figure 1 and Figure 2 As shown, when it is necessary to dispense milk powder in bottles of different heights, it is only necessary to start the first rotary drive 400 to transmit power to the gear assembly 500. Since the gear assembly 500 meshes with the first rack 200, the power will be transmitted to the first rack 200. Furthermore, the gear assembly 500 is mounted on the movable frame 300, which can drive the movable frame 300 to move in the direction guided by the guide 100, so as to realize the dispensing of milk powder according to different bottle heights and improve the overall practicality.

[0041] In this embodiment, there are two guide members 100. The first rack 200 is fixedly installed on one of the guide members 100. Specifically, the first rack 200 is fixedly set on the top of the guide member 100. The movable frame 300 has a corresponding guide groove, which is slidably connected to the guide member 100. Under the linkage of the first rotary drive member 400, the gear assembly 500 and the first rack 200, the movable frame 300 moves about the guide member 100. It can be understood that the first preset direction mentioned above is the height direction, that is, the movable frame 300 can be height adjusted, thereby adjusting the height of the unloading device 600 installed on the movable frame 300.

[0042] In one embodiment, the entire device can be controlled to start and stop via a corresponding controller.

[0043] The gear assembly 500 includes a first gear 510 mounted on the output shaft of the first rotary drive 400. The first gear 510 is connected to a second gear 520 and a third gear 530. Both the second gear 520 and the third gear 530 mesh with the first gear 510 for transmission. The second gear 520 meshes with the first rack 200 for transmission.

[0044] The second gear 520 includes a driving gear and a driven gear. The driving gear meshes with the first gear 510 for transmission, and the driven gear meshes with the first rack 200 for transmission.

[0045] See Figures 1 to 4As shown, the driving wheel and driven wheel of the second gear 520 are integrally formed, meaning that the driving wheel and driven wheel can rotate synchronously. When the first rotary drive 400 is activated, it drives the first gear 510 to rotate. Since the first gear 510 meshes with the driving wheel of the second gear 520, the first gear 510 drives the driving wheel to rotate, which in turn causes the driven wheel to rotate. Since the driven wheel meshes with the first rack 200, the power is transmitted to the first rack 200. It can be understood that the first rack 200 is fixedly installed on the guide 100, meaning the first rack 200 is fixed. Thus, when the driven wheel of the second gear 520 rotates, the entire movable frame 300 can move up and down, realizing the position adjustment of the movable frame 300. This allows the entire device to adapt to different bottle heights, improving its practicality.

[0046] This application embodiment also provides a quantitative feeding device, which includes the height adjustment mechanism described above, and further includes a feeding device 600, a second rack 700, and a power assembly 800.

[0047] In some embodiments, the feeding device 600 is mounted on the movable frame 300, a fixed frame 310 is provided on one side of the movable frame 300, the second rack 700 is slidably mounted on the top of the movable frame 300, a mounting frame is provided on one side of the second rack 700, a sealing member 710 is detachably mounted on the end of the second rack 700, the sealing member 710 is located inside the mounting shell 610 and at the outlet position of the feeding shell 620, the sealing member 710 moves with the second rack 700, the power component 800 is fixedly mounted on the movable frame 300, the power component 800 is drively connected to the second rack 700, and the power component 800 is used to drive the second rack 700 to move along a second preset direction.

[0048] See Figure 2 , Figure 3 as well as Figure 4 As shown, after the height of the movable frame 300 is adjusted by the height adjustment mechanism, the feeding device 600 reaches the predetermined position. Then, the power component 800 drives the second rack 700 to move along the second preset direction (left-right lateral direction), thereby moving the sealing member 710 away from the outlet direction of the feeding device 600, releasing the blockage on the outlet direction of the feeding device 600, and allowing the feeding device 600 to feed normally. It can be understood that the power component 800 drives the second rack 700 to move, thereby moving the sealing member 710 as well, which can block or open the outlet of the feeding device 600, preventing the powder (milk powder) inside the feeding device 600 from getting damp and becoming inedible or contaminated when not in use.

[0049] It is understood that the second preset direction mentioned above is the left and right movement direction of the second rack 700, wherein the second rack 700 can be slidably connected to the moving frame 300 by means of a groove and a slider.

[0050] Please see Figure 2 , Figure 3 as well as Figure 4 As shown, the fixing bracket 310 is mainly used for the rotational installation of the third gear 530, the second gear 520 and the first gear 510, and provides support for the rotation of the third gear 530, the second gear 520 and the first gear 510.

[0051] The feeding device 600 includes a mounting shell 610 fixedly installed on the movable frame 300. The mounting shell 610 has a receiving cavity, in which a feeding shell 620 is fixedly installed. A screw 630 is fixedly installed inside the feeding shell 620. The end of the screw 630 extends axially to the outside of the feeding shell 620, and a second transmission groove 640 is formed on the end face of the screw 630.

[0052] See Figure 2 , Figure 3 as well as Figure 5 As shown, the mounting shell 610 is fixedly mounted on the movable frame 300. The feeding shell 620 is fixedly installed in the accommodating cavity inside the mounting shell 610. The feeding shell 620 has two ports, one for discharging and the other for transmission. Furthermore, a screw 630 is rotatably mounted inside the feeding shell 620. One end of the screw 630 extends to the port position of the feeding shell 620, and a second transmission groove 640 for transmission is opened at the end of the screw 630. A transmission component adapted to the second transmission groove 640 extends into the second transmission groove 640 to drive the screw 630 to rotate, thereby quantitatively discharging and discharging the powder (milk powder) located in the feeding shell 620.

[0053] It is understandable that the screw 630 has the function of quantitatively conveying powdered products. Specifically, the screw 630 can refer to the existing auger conveyor structure, which is existing technology and will not be elaborated on here.

[0054] The second rack 700 has a limiting groove 701 at its end facing the sealing member 710, and the sealing member 710 has a limiting block 711 at its end facing the second rack 700. The limiting block 711 extends into the limiting groove 701 and engages with it to connect the sealing member 710 and the second rack 700.

[0055] See Figure 5As shown, to facilitate the disassembly and installation of the sealing component 710 and the second rack 700, a limiting groove 701 is provided at the end of the second rack 700 near the sealing component 710, and a limiting block 711 is provided at the end of the sealing component 710 facing the second rack 700. The limiting block 711 is inserted into the limiting groove 701 to complete the installation of the sealing component 710 and the second rack 700, so that the sealing component 710 can move with the second rack 700. Specifically, the limiting groove 701 is formed on the semi-circular shell, and the semi-circular shell and the second rack 700 are integrally formed. The limiting groove 701 is semi-circular. Correspondingly, a semi-circular protrusion is also provided on the outer surface of the end of the sealing component 710. It can be understood that the limiting block 711 can be set on the limiting groove 701, and the limiting groove 701 is set on the sealing component 710.

[0056] The power assembly 800 includes a second rotary drive 810 fixedly mounted on the movable frame 300. A drive gear 820 is fixedly mounted on the output end of the second rotary drive 810. The drive gear 820 meshes with the second rack 700 for transmission. The second rotary drive 810 drives the drive gear 820 to rotate, thereby causing the second rack 700 to move along a second preset direction.

[0057] See Figure 3 As shown, when the second rack 700 needs to move, the second rotary drive 810 is activated to drive the drive gear 820 to rotate. Since the drive gear 820 meshes with the second rack 700, the rotation of the drive gear 820 will cause the second rack 700 to slide left and right, thereby causing the sealing member 710 to close or open the outlet of the unloading shell member 620.

[0058] The third gear 530 is provided with a transmission assembly 531. The transmission assembly 531 includes a transmission hole 5311 opened at the center of the third gear 530. A transmission rod 5312 is slidably installed in the transmission hole 5311. The transmission rod 5312 is rotatably installed on the mounting bracket. The transmission rod 5312 can move along the circumferential direction of the third gear 530. A second transmission block 5313 is fixedly installed at the end of the transmission rod 5312 away from the third gear 530. The second transmission block 5313 can penetrate into the second transmission groove 640 and engage with it for transmission.

[0059] See Figure 4 , Figure 5 as well as Figure 6As shown, a mounting bracket is fixedly installed at the end of the second rack 700 away from the sealing member 710. This mounting bracket is mainly used for the installation of the transmission rod 5312 and the first transmission block 521. Specifically, the transmission rod 5312 is rotatably mounted on the mounting bracket. The transmission rod 5312 passes through the transmission hole 5311 and is engaged with the transmission hole 5311. The transmission rod 5312 and the transmission hole 5311 can slide left and right. That is, when the third gear 530 rotates, it drives the transmission rod 5312 to rotate. At the same time, the transmission rod 5312 can also move left and right relative to the third gear 530. Specifically, a second transmission block 5313 adapted to the second transmission groove 640 is installed at the end of the transmission rod 5312 away from the third gear 530. When the second transmission block 5313 is inserted into the second transmission groove 640, the third gear 530 drives the transmission rod 5312 to rotate, which in turn drives the second transmission block 5313 to rotate, thereby driving the screw 630 to rotate to achieve quantitative feeding.

[0060] For example, the shapes of the transmission hole 5311 and the transmission rod 5312 are adapted to each other, and the two can realize rotational transmission after they are combined. For example, the cross-sectional shape of the transmission hole 5311 and the transmission rod 5312 can be rectangular, pentagonal, hexagonal, heptagonal, octagonal, slotted, or other non-circular shapes.

[0061] For example, the shapes of the second transmission block 5313 and the second transmission groove 640 can be adapted to each other. The shapes of the second transmission block 5313 and the second transmission groove 640 can be conical quadrilaterals, pentagons, hexagons, etc., and there is no specific limitation, as long as the two can achieve snap-fit ​​transmission.

[0062] The second gear 520 is rotatably mounted on the fixed frame 310. A first transmission block 521 is provided on one side of the second gear 520. The first transmission block 521 is provided on the mounting frame. A rotating shaft 522 is provided at the center of the first transmission block 521 and is rotatably connected to a bracket on one side. The first transmission block 521 is rotatably connected to the rotating shaft 522. The second gear 520 and the first transmission block 521 move with the second rack 700. The moving frame 300 is also provided with a first transmission groove 320 that is adapted to the first transmission block 521.

[0063] See Figure 3 and Figure 4As shown, it can be understood that when the second rack 700 moves, it will drive the mounting bracket on one side to move. The transmission rod 5312, the first transmission block 521, and the second gear 520 mounted on the mounting bracket will also move together. At this time, the driving gear of the second gear 520 will no longer mesh with the first gear 510, but the driven gear of the second gear 520 will always be meshed with the first rack 200. When the first transmission block 521 moves with the second rack 700, the first transmission block 521 will be driven by the second rack 700 to move into the first transmission groove 320. Through the first transmission groove 320, the first transmission block 521 and the second gear 520 will no longer rotate. Since the driven gear of the second gear 520 is meshed with the first rack 200, the moving frame 300 is in a fixed state at this time.

[0064] In this embodiment, in order for the second gear 520 to disengage and mesh with the first gear 510, the second gear 520 and the first transmission block 521 need to move axially. Specifically, the rotating shaft 522 is rotatably mounted on the fixed frame 310, and the rotating shaft 522 can move axially relative to the fixed frame 310. Thus, the rotating shaft 522 can move axially synchronously with the second gear 520 and the first transmission block 521, that is, the second gear 520 and the first transmission block 521 are not obstructed or constrained in the axial direction.

[0065] At least one position sensor 900 is fixedly installed on the movable frame 300, and the position sensor 900 is located on the moving path of the second rack 700.

[0066] See Figure 2 and Figure 3 As shown, in order to determine whether the sealing component 710 opens the opening of the unloading shell 620, whether the second transmission block 5313 is inserted into the second transmission groove 640, and whether the first transmission block 521 is inserted into the first transmission groove 320, a position sensor 900 is installed on the moving frame 300. The position sensor 900 is used to determine whether the second rack 700 drives the sealing component 710, the second transmission block 5313, and the first transmission block 521 to the predetermined position. Specifically, in this embodiment, two position sensors 900 can be set on the moving frame 300, one for sensing and determining whether the sealing component 710 has reached the predetermined position, and the other for sensing and determining whether the second transmission block 5313 and the first transmission block 521 have reached the predetermined position.

[0067] The first transmission groove 320 and the first transmission block 521 are adapted to each other in shape and are connected by snap-fit. For example, the shapes of the first transmission groove 320 and the first transmission block 521 can be conical quadrilaterals, pentagons, hexagons, etc., and there is no specific limitation, as long as the two can achieve snap-fit ​​transmission.

[0068] For example, the position sensor 900 can be a photoelectric switch, a limit switch, etc.

[0069] The working process of this utility model is as follows: First, the rotational power is transmitted to the first gear 510 through the first rotary drive member 400. The first gear 510 meshes with the second gear 520, and the second gear 520 meshes with the first rack 200. Therefore, when the second gear 520 rotates, the moving frame 300 moves up and down about the guide member 100, thereby moving the unloading device 600 to a predetermined height. Next, the power component 800 drives the second rack 700 to move. At this time, the sealing member 710 releases the seal on the outlet of the unloading shell 620, and at the same time drives the transmission rod 5312 to move axially relative to the third gear 530, causing the second transmission block 5313 to penetrate deeper into the second rack 200. The transmission groove 640 is driven to extend the first transmission block 521 into the first transmission groove 320. At this time, since the second gear 520 and the first gear 510 are disengaged (the two are separated at this time), the height of the moving frame 300 is fixed in the state of the first transmission block 521 and the first transmission groove 320 being engaged. At this time, the third gear 530 and the first gear 510 are always engaged. The first rotary drive member 400 drives the first gear 510 to rotate and then drives the third gear 530 to rotate. Through the transmission rod 5312 and the second transmission block 5313, the second transmission groove 640 is driven to rotate, and the powder (milk powder) in the feeding shell 620 is quantitatively fed.
