A press-to-pop structure for a wastewater tank and its milk maker

Abstract

This utility model discloses a press-and-pop structure for a wastewater tank and its formula maker. The structure is located on the side wall of the formula maker and protrudes outwards, with the protruding portion abutting against the wastewater tank. It includes a pressing channel and a pressing member disposed within the pressing channel. The pressing channel is located inside the formula maker, and the pressing member is located on the outward-facing side of the pressing channel and protrudes outwards. A rotating member and an elastic member are sequentially arranged on the inward-facing side of the pressing channel. The elastic member abuts against the rotating member and consistently applies elastic force to the rotating member. The pressing channel contains a sliding groove and a locking slot. By sliding the pressing member along the sliding groove and pressing the rotating member, the rotating member rotates circumferentially and sequentially falls into the sliding groove and locking slot. The different depths of the sliding groove and locking slot result in different outward protrusion distances of the pressing member, thus achieving the effect of popping out the wastewater tank. When the wastewater tank is pressed again, the outward protrusion distance of the pressing member decreases, and the wastewater tank returns to its original position.

Description

Technical Field

[0001] This utility model belongs to the field of formula maker technology, specifically relating to a press-and-pop structure for a wastewater tank and its formula maker. Background Technology

[0002] Traditional formula warmers use a single water tank structure. If the heated water is not used up promptly, it will remain in the pipes, requiring wastewater to be drained. This led to the development of formula warmer wastewater tank technology. The emergence of this technology marks a leap from "functional" to "health-oriented" infant feeding tools. Through innovations such as automatic wastewater discharge, dual-tank separation, and intelligent temperature control, it solves the hygiene hazards and operational pain points of traditional equipment, becoming an essential childcare tool for modern families. In the future, with the development of materials science and IoT technology, wastewater tank technology will further evolve towards "seamless" and "personalized" solutions, providing a more solid guarantee for the healthy growth of infants and young children.

[0003] Currently, there are more and more types of formula makers with wastewater tanks on the market. The existing wastewater tank designs are basically handled by the sides or have a notch at the top for easy handling and removal, which affects the overall aesthetics. Some formula makers have wastewater tanks with the edge flush with the maker and no notch, making it extremely inconvenient to remove the wastewater tank and affecting the user experience. Summary of the Invention

[0004] To address the problems in related technologies, this utility model proposes a press-and-pop structure for a wastewater tank and its milk mixer. By pressing the wastewater tank of the milk mixer, the wastewater tank is pressed and popped out of the structure. The pop-out structure then pops out the wastewater tank in the opposite direction, or the structure and the wastewater tank are reset by pressing again.

[0005] This utility model is implemented as follows:

[0006] A press-and-pop structure for a wastewater tank is provided on the side wall of a formula maker and protrudes outward, with the protruding part abutting against the wastewater tank.

[0007] The device includes a pressing channel and a pressing component disposed within the pressing channel. The pressing channel is located inside the formula maker, and the pressing component is located on the outward side of the pressing channel and protrudes outward. A rotating component and an elastic component are sequentially disposed on the inward side of the pressing channel. The elastic component abuts against the rotating component and always applies elastic force to the rotating component.

[0008] The inner wall of the pressing channel is provided with several inwardly opening grooves and slots. The grooves and slots are adjacent to each other, and the adjacent grooves and slots are inclined. The outward extension distance of the groove is greater than that of the slot. The pressing member is engaged with the groove and moves back and forth along the groove. One end of the rotating member abuts against the elastic member, and the other end faces the side where the pressing member is located, abuts against the slot or enters the groove, and abuts against the pressing member in the groove.

[0009] Pushing the wastewater tank causes it to apply pressure to the pressing component. The pressing component lifts the rotating component along the slide groove, causing the rotating component to slide sequentially along the circumference to the slot or slide groove while simultaneously driving the rotating component to rotate. This results in either a first state where the rotating component slides and abuts into the slot, or a second state where the rotating component slides into the slide groove and abuts against the pressing component.

[0010] Preferably, the pressing member has an annular serrated shape on the inward side of the pressing channel, and its protruding part forms an abutment ridge; the rotating member has an abutment block corresponding to the abutment ridge in the direction of the pressing member, and the abutment block abuts against the slot, or enters the sliding groove to abut against the abutment ridge of the pressing member.

[0011] Specifically, the ring-shaped sawtooth pattern, i.e., continuous triangles, has protruding angles forming the edges that act as abutments. Both sides of the abutment edge are inclined structures. The side of the abutment block that connects with the abutment edge is inclined towards one side of the abutment edge, adapting to the inclined structure of one side of the abutment edge. It can slide along one of the inclined surfaces.

[0012] Preferably, the abutting edge includes an inner abutting edge and an outer abutting edge, the outer abutting edge protruding outward to form an inner abutting edge; the inner abutting edge is located within the sliding groove, and the outer abutting edge is located between two adjacent inner abutting edges.

[0013] Specifically, the inner abutment edge is located inside the groove, while the outer abutment edge is not inside the groove but between the grooves.

[0014] When the abutting block is in the slot, the abutting edge outside the slot is used to lift the abutting block, so that it slides into the adjacent slot and abuts against the abutting edge inside the slot;

[0015] When the abutting block is in the groove, the abutting edge in the groove will lift the abutting block up, so that it slides into the adjacent slot and abuts against the slot.

[0016] The radius of the outward expansion of the inner abutment edge is greater than that of the outer abutment edge.

[0017] Preferably, the number of abutting blocks is half the number of abutting edges.

[0018] Specifically, when the pressing part moves, the abutment block always abuts against all the abutment edges inside the groove or all the abutment edges outside the groove. The abutment block cannot abut against both the abutment edges inside the groove and the abutment edges outside the groove at the same time.

[0019] Preferably, the pressing member is a cylinder with an opening at one end, with one end of the opening facing the interior of the pressing channel and the other end connected to the wastewater tank; the abutment ridge is located at the open end of the pressing member.

[0020] Specifically, the pressing element is located inside the pressing channel, and the groove outer abutment edge slides outward from the inside of the pressing channel into the groove.

[0021] Preferably, the rotating component has a circular structure, and an abutting block is formed by extending outward from the periphery of the rotating component. The side of the abutting block facing the abutting edge is an inclined surface. The rotating component has a raised ring edge on the side facing the pressing component. When the pressing component abuts against the rotating component, the ring edge is located inside the pressing component.

[0022] Specifically, the rotating component is similar to a disc, with the side facing the elastic component having a flat center and raised annular retaining edges on its periphery. The elastic component abuts against the flat center of the rotating component, and the retaining edges on its periphery prevent the elastic component from sliding or moving out of the flat center. The side of the abutting block that contacts the abutting edge is inclined towards one side of the abutting edge.

[0023] Preferably, the inner side of the pressing channel protrudes inward to form the slot and the slide groove; one side of the slide groove is inclined along the periphery of the pressing channel to form a long inclined surface, and one side of the slot is inclined along the periphery of the pressing channel to form a short inclined surface. The shallow recess formed between the long inclined surface and the short inclined surface is the slot; the deep recess formed between the long inclined surface and the short inclined surface is the slide groove; the depth of the slide groove is greater than the depth of the slot.

[0024] Specifically, the side of the chute facing outward is not connected to the outside; the pressing channel is integrally formed with the housing of the milk maker.

[0025] Preferably, the outer side of the pressing channel is fitted with a shell, which is a cylinder with an opening on one side and a cross-shaped protrusion on the bottom of its inner side. The elastic element abuts against the bottom of the shell, and the cross-shaped protrusion is located inside the elastic element. The shell is located at the inward end of the pressing channel and is fitted onto the outer side of the pressing channel, and is fixedly connected to the pressing channel.

[0026] Specifically, if the outer shell is not fitted over the pressing channel, the pressing channel is a cylinder with an opening on one side, and one side of the elastic element abuts against the bottom of the pressing channel; if the outer shell is fitted over the pressing channel, the pressing channel is a hollow cylinder, and the elastic element abuts against the bottom of the shell.

[0027] Preferably, the outer side of the pressing channel is provided with a connecting groove, and the inner side of the outer shell is provided with a protrusion corresponding to the connecting groove; the connecting groove and the protrusion are engaged and connected.

[0028] Specifically, the outer shell is located inside the formula maker, and the pressing channel is fixedly connected to the outer shell through connecting grooves and protrusions.

[0029] A formula maker that utilizes a press-to-pop structure for a wastewater tank as described in any of the above claims.

[0030] Compared with the prior art, the present invention achieves the following beneficial effects:

[0031] This utility model provides a press-and-pop structure for a wastewater tank and its formula maker, including a press channel. A pressing component, a rotating component, and an elastic component are sequentially arranged within the press channel. The elastic component consistently applies elastic force to the rotating component. The press channel is provided with a sliding groove and a locking slot. The pressing component slides along the sliding groove and presses the rotating component, causing the rotating component to rotate circumferentially and sequentially fall into the sliding groove and locking slot. The different depths of the sliding groove and locking slot result in different outward protrusions of the pressing component, thus achieving the effect of popping out the wastewater tank. When the wastewater tank is pressed again, the outward protrusion of the pressing component shortens, and the wastewater tank returns to its original position. This design differs from the direct removal method of existing technologies and avoids the inconvenience of removing the wastewater tank when it is stuck in the formula maker due to its edge being flush with the maker. It also eliminates the need for a notch, enhancing aesthetics, ease of use, and improving the user experience. Attached Figure Description

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] Example

[0054] like Figures 1 to 12 A press-and-pop structure for a wastewater tank 2 is provided on the side wall of the formula maker 1 and protrudes outward, with the protruding part abutting against the wastewater tank 2.

[0055] It includes a pressing channel 3 and a pressing member 4 disposed in the pressing channel 3. The pressing channel 3 is located inside the formula maker 1. The pressing member 4 is located on the outward side of the pressing channel 3 and protrudes outward. The inward side of the pressing channel 3 is provided with a rotating member 5 and an elastic member 6 in sequence. The elastic member 6 abuts against the rotating member 5 and always applies elastic force to the rotating member 5.

[0056] The inner wall of the pressing channel 3 is provided with several inwardly opening grooves 31 and slots 32. The grooves 31 and slots 32 are adjacent to each other, and the adjacent grooves 31 and slots 32 are inclined. The outward extension distance of the grooves 31 is greater than that of the slots 32. The pressing member 4 is engaged with the grooves 31 and moves back and forth along the grooves 31. One end of the rotating member 5 abuts against the elastic member 6, and the other end faces the side where the pressing member 4 is located, abuts against the slot 32 or enters the groove 31, and abuts against the pressing member 4 in the groove 31.

[0057] Pushing the wastewater tank 2 causes it to apply pressure to the pressing member 4. The pressing member 4 lifts the rotating member 5 along the slide groove 31, causing the rotating member 5 to slide along the circumference to the slot 32 or the slide groove 31 in sequence. At the same time, the rotating member 5 is driven to rotate, resulting in the first state where the rotating member 5 slides and abuts into the slot 32, or the second state where the rotating member 5 slides into the slide groove 31 and abuts against the pressing member 4.

[0058] The formula maker 1 is equipped with a wastewater tank 2 and the elastic element 6 is a spring.

[0059] The outer side of the pressing channel 3 is fitted with a shell 7, which is a cylinder with an opening on one side. The bottom of the inner side of the shell 7 is provided with a cross-shaped protrusion 71. The elastic member 6 abuts against the bottom of the shell 7, and the cross-shaped protrusion 71 is located inside the elastic member 6. The shell 7 is located at the inward end of the pressing channel 3 and is fitted onto the outer side of the pressing channel 3, and is fixedly connected to the pressing channel 3.

[0060] If the outer shell 7 is not fitted over the outer side of the pressing channel 3, the pressing channel 3 is a cylinder with an opening on one side, and one side of the elastic element 6 abuts against the bottom of the pressing channel 3; if the outer shell 7 is fitted over the outer side of the pressing channel 3, the pressing channel 3 is a hollow cylinder, and the elastic element 6 abuts against the bottom of the outer shell 7.

[0061] The outer side of the pressing channel 3 is provided with a connecting groove 35, and the inner side of the outer shell 7 is provided with a protrusion 72 corresponding to the connecting groove 35; the connecting groove 35 and the protrusion 72 are engaged and connected.

[0062] The outer casing 7 is located inside the formula maker 1, and the pressing channel 3 is fixedly connected to the outer casing 7 through the connecting groove 35 and the protrusion 72.

[0063] The pressing member 4 is serrated on the inward side of the pressing channel 3, and its protruding part forms an abutment ridge 41; the rotating member 5 is provided with an abutment block 51 corresponding to the abutment ridge 41 in the direction of the pressing member 4. The abutment block 51 abuts against the slot 32, or enters the sliding groove 31 and abuts against the abutment ridge 41 of the pressing member 4.

[0064] The ring-shaped sawtooth shape, i.e., the continuous triangle, has protruding corners forming the edge of the abutment edge 41. Both sides of the abutment edge 41 are inclined structures. The side of the abutment block 51 that connects with the abutment edge 41 is inclined towards one side of the abutment edge 41, adapting to the inclined structure of one side of the abutment edge 41; it can slide along one side of the inclined surface.

[0065] The abutting edge 41 includes an inner abutting edge 411 and an outer abutting edge 412. The outer abutting edge 412 protrudes outward to form the inner abutting edge 411. The inner abutting edge 411 is located inside the sliding groove 31, and the outer abutting edge 412 is located between two adjacent inner abutting edges 411.

[0066] The inner abutting edge 411 is located inside the sliding groove 31, while the outer abutting edge 412 is not inside the sliding groove 31, but between the sliding grooves 31.

[0067] When the abutting block 51 is located in the slot 32, the abutting edge 412 outside the slot is used to lift the abutting block 51, so that it slides into the adjacent slot 31 and abuts against the abutting edge 411 inside the slot.

[0068] When the abutting block 51 is located in the sliding groove 31, the abutting edge 411 in the groove is used to lift the abutting block 51, so that it slides into the adjacent slot 32 and abuts against the slot 32.

[0069] The radius of the outward expansion of the inner groove abutment 411 is greater than that of the outer groove abutment 412.

[0070] The number of abutting blocks 51 is half the number of abutting edges 41.

[0071] When the pressing part 4 moves, the abutting block 51 always abuts against all the abutting edges 411 inside the groove or all the abutting edges 412 outside the groove. The abutting block 51 cannot abut against both the abutting edges 411 inside the groove and the abutting edges 412 outside the groove at the same time.

[0072] The pressing member 4 is a cylinder with an opening at one end, with one end of the opening facing the inside of the pressing channel 3 and the other end connected to the wastewater tank 2; the abutment ridge 41 is located at the open end of the pressing member 4.

[0073] The pressing member 4 is located inside the pressing channel 3, and the groove outer abutting edge 412 slides outward from the inside of the pressing channel 3 into the sliding groove 31.

[0074] The rotating component 5 has a circular structure, and an abutting block 51 is formed by extending outward from the periphery of the rotating component 5. The side of the abutting block 51 facing the abutting edge 41 is an inclined surface. The rotating component 5 has a protruding ring edge 52 on the side facing the pressing component 4. When the pressing component 4 abuts against the rotating component 5, the ring edge 52 is located inside the pressing component 4.

[0075] The rotating component 5 is similar to a disk, with one side facing the elastic component 6. Its center is a flat plane, and its periphery has raised annular retaining edges 53. The elastic component 6 abuts against the flat plane in the center of the rotating component 5, and the retaining edges 53 prevent the elastic component 6 from sliding or moving out of its center plane. The side of the abutting block 51 that contacts the abutting ridge 41 is inclined towards one side of the abutting ridge 41.

[0076] The inner side of the pressing channel 3 protrudes inward to form the slot 32 and the slide groove 31; one side of the slide groove 31 is inclined along the periphery of the pressing channel 3 to form a long inclined surface 33, and one side of the slot 32 is inclined along the periphery of the pressing channel 3 to form a short inclined surface 34. The shallow recess formed between the long inclined surface 33 and the short inclined surface 34 is the slot 32; the deep recess formed between the long inclined surface 33 and the short inclined surface 34 is the slide groove 31; the depth of the slide groove 31 is greater than the depth of the slot 32.

[0077] That is, the slide groove 31 is a deep groove and the slot 32 is a shallow groove. By utilizing the different depths of the slide groove 31 and the slot 32, the pressing part 4 protrudes outward by different distances. During the pressing process, the pressing part 4, the rotating part 5, and the elastic part 6 are all in abutting state, thereby realizing the pop-out or reset of the wastewater tank 2.

[0078] The side of the chute 31 facing outward is not connected to the outside; the pressing channel 3 is integrally formed with the shell of the milk maker 1.

[0079] A formula maker 1 uses a press-to-pop structure for a wastewater tank 2 as described in any of the above claims.

[0080] This utility model provides a press-and-pop structure for a wastewater tank 2 and its formula dispenser 1. Pushing the wastewater tank 2 causes it to apply pressure to the pressing member 4. The abutting edge 41 of the pressing member 4 pushes the abutting block 51 of the rotating member 5 away from the slot 32 along the slide groove 31, causing it to slide along the inclined surface adjacent to the slot 32. The rotating member 5 also rotates, causing the abutting block 51 to slide into the adjacent slide groove 31. The abutting block 51 pushes the abutting edge 41 outward in the slide groove 31, and pushes the pressing member 4 outward through the abutting edge 41, thus popping the wastewater tank 2 outward through the pressing member 4.

[0081] The wastewater tank 2 is pushed again to apply pressure to the pressing member 4. The abutting edge 41 of the pressing member 4 pushes the abutting block 51 of the rotating member 5 away from the slide groove 31 along the slide groove 31, so that it slides along the inclined surface adjacent to the slide groove 31. The rotating member 5 continues to rotate, so that the abutting block 51 slides into the adjacent slot 32. The depth of the slot 32 is less than the depth of the slide groove 31. The distance of the pressing member 4 protruding outward becomes smaller, and the wastewater tank 2 returns to its original position, completing the reset of the wastewater tank 2.

[0082] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
