Description

Technical Field

[0001] This utility model belongs to the field of formula milk maker technology, specifically relating to a flowing formula milk maker. Background Technology

[0002] In modern family childcare settings, bottle warmers are an important auxiliary tool. Their main function is to heat the milk in the bottle to a suitable temperature for infants. Currently, there are many types of bottle warmers on the market. For example, Chinese patent CN206197789U discloses a water bath bottle warmer and its temperature control device. This warmer includes a potentiometer and a thermistor, with the potentiometer connected to a PCB control board. This prior art uses a potentiometer with adjustable settings for temperature control, each setting corresponding to a specific temperature value. This ensures that errors in the adjustment knob angle do not affect the selected temperature, improving temperature control accuracy and adaptability.

[0003] However, although the aforementioned existing technologies meet the basic need for warming milk to some extent, they have revealed many problems in practical applications:

[0004] Firstly, for certain usage scenarios, such as warming milk multiple times at night, the frequent water refilling issue of traditional water bath bottle warmers becomes particularly prominent. Since the water level in the bottle warmer decreases after each use, users need to repeatedly add water to ensure proper functioning for the next use. This is extremely inconvenient for new parents.

[0005] Secondly, the aforementioned existing technologies primarily utilize static water to heat the bottle, relying on the heat conduction of the water to heat the milk inside. This process is relatively slow, especially when the water temperature is low or the bottle capacity is large, potentially extending the heating time. For parents who urgently need to feed their babies, this could increase the time cost of feeding.

[0006] Furthermore, during the prolonged use of static water in a bottle warmer, the water remains relatively still, providing a favorable environment for the growth and reproduction of microorganisms. Even with regular water changes, it is difficult to completely prevent the residue and proliferation of microorganisms inside the bottle warmer. Summary of the Invention

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.

[0060] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0061] like Figure 1-9 As shown, this embodiment provides a flowing formula maker, including a base 1 and a formula maker assembly 2. The base 1 has a formula maker cavity 141, and the formula maker assembly 2 is disposed in the formula maker cavity 141. The formula maker assembly 2 includes a clamping device 21 and a storage basket 22 nested above and below. The storage basket 22 is used to support the bottom of the bottle, and the clamping device 21 is used to clamp the body of the bottle.

[0062] It also includes a water storage tank 3, a circulating water circuit structure, and a water flow drive module;

[0063] The circulating water system includes an inlet channel 4 and a return channel 5. The formula mixing chamber 141 is connected to the water storage tank 3 through the inlet channel 4 and the return channel 5 respectively. The water in the water storage tank 3 is supplied with cold / hot water to the formula mixing chamber 141 through the inlet channel 4, and the water in the formula mixing chamber 141 is returned to the water storage tank 3 through the return channel 5, forming a dynamic water circulation.

[0064] The water inlet channel 4 is equipped with a heating device 8 for heating the water.

[0065] The water flow drive module includes a drive unit and an impeller 7. The impeller 7 is located at the bottom of the milk preparation chamber 141. The output end of the drive unit is connected to the impeller 7 to drive the impeller 7 to rotate in the milk preparation chamber 141. The blades of the impeller 7 push the surrounding water, so that the water gains kinetic energy and forms a circular motion in the milk preparation chamber 141 along the rotation direction of the impeller 7.

[0066] First, the formula warmer in this embodiment forms a dynamic water circulation by setting up a circulating water circuit structure that connects the water tank 3 and the formula warming chamber 141 through the water inlet channel 4 and the return channel 5; this avoids the water volume decreasing after each warming of the formula, and users do not need to manually add water repeatedly, greatly improving the convenience of use.

[0067] Secondly, in this embodiment, the water inlet channel 4 of the formula maker is equipped with a heating device 8, and the water flow drive module drives the impeller 7 to rotate and drive the water flow. The flowing water accelerates the heat transfer and effectively shortens the heating time to meet the needs of parents who urgently need to feed their babies.

[0068] Moreover, the dynamic water circulation of the formula maker in this embodiment can effectively reduce the residence time of water in the formula maker chamber 141, disrupt the microbial growth environment, reduce the risk of microbial growth, and ensure the hygiene and safety of the formula maker process.

[0069] In addition, the clamping device 21 and the storage basket 22 in the formula preparation component 2 are nested one above the other. The clamping device 21 can hold the bottle body and the storage basket 22 supports the bottle bottom, which can accommodate bottles of different sizes and shapes and expand the product's applicability.

[0070] Specifically, the drive unit drives the impeller 7 to rotate intermittently in one direction within the milk preparation chamber 141; or,

[0071] The drive unit drives the impeller 7 to rotate intermittently in the milk mixing chamber 141 in both forward and reverse directions. The forward rotation causes the water to form a vortex in one direction, while the reverse rotation forms a vortex in the opposite direction. The interaction of the two vortices allows the water in the milk mixing chamber 141 to be mixed more evenly, reducing local differences in water temperature.

[0072] It should be noted that: driving the impeller 7 to rotate intermittently in one direction means that the output end of the drive unit is preset to rotate in either the forward or reverse direction. After each rotation, it stops for a period of time, and the stopping time can be preset. For example, after rotating forward once, it stops for a period of time, then rotates forward once again, and so on. Driving the impeller 7 to rotate intermittently in both forward and reverse directions within the milk mixing chamber 141 means that the output end of the drive unit is set to rotate alternately in both the forward and reverse directions. For example, after rotating forward once, it stops for a period of time, then rotates in the reverse direction once, stops for a period of time, then rotates forward once again, and so on.

[0073] Specifically, the bottom of the storage basket 22 is connected to the bottom surface of the milk preparation chamber 141 through a snap-fit ​​structure; the side wall and / or bottom of the storage basket 22 are provided with a plurality of perforated holes 221 for water flow, and the shape of the perforated holes 221 includes circular, elliptical or square.

[0074] More specifically, the bottom of the storage basket 22 is connected to the bottom surface of the groove 14 through a snap-fit ​​structure to ensure that the storage basket 22 is stably placed and accurately positioned in the milk preparation chamber 141;

[0075] The clamping device 21 includes a clamping cover 211 and an elastic ring frame 212 arranged sequentially from top to bottom. The elastic ring frame 212 is built into the upper end of the storage basket 22 and extends towards the bottom of the storage basket 22. The clamping device 21 also includes a plurality of clamping pieces 2121 spaced around the elastic ring frame 212. The plurality of clamping pieces 2121 extend inward and downward to form a clamping opening for clamping the baby bottle.

[0076] Specifically, the storage basket 22 is located directly above the impeller 7, and there is a gap between the outer bottom surface of the storage basket 22 and the impeller 7;

[0077] The locking structure includes a locking pin 222 and a locking groove 223 that are locked together. The locking pin 222 extends from the bottom of the storage basket 22 toward the bottom surface of the milk preparation chamber 141, and the bottom surface of the milk preparation chamber 141 is provided with the locking groove 223.

[0078] More specifically, the latch 222 extends from the bottom of the storage basket 22 toward the bottom surface of the groove 14, and the bottom surface of the groove 14 is provided with the latch 223;

[0079] When the storage basket 22 is placed into the formula mixing chamber 141, the locking pin 222 slides in along the locking groove 223 to guide and position the storage basket 22 within the formula mixing chamber 141, thereby restricting the movement of the storage basket 22 within the formula mixing chamber 141 and further improving the installation stability of the storage basket 22.

[0080] It should be noted that the above is only one example of the implementation of the locking structure. The locking structure described in this embodiment has many other implementations, such as magnetic locking; other locking structures also have the same technical effect.

[0081] Specifically, the base 1 includes an upper shell 11 and a lower shell 12 that are separated into upper and lower parts.
