[0002] At present, the milk warmer can not only shake the milk by the rotation of the motor, but also warm the milk by the heating element. Since the baby bottle rotates in the milk shaking rack, it is not convenient for the temperature sensing contact on the housing of the milk shaker to directly contact the baby bottle. The temperature sensing position is mainly set at the position on the housing of the milk shaker close to the milk shaking rack. For example, the setting position of the temperature sensor proposed in the Chinese utility model "A Multifunctional Milk Shaker" with the publication number CN215533694U: The milk shaking device includes a rotating cylinder for fixing the baby bottle, a driving motor and an installation inner shell. The output shaft of the driving motor is connected to the rotating cylinder to drive the rotating cylinder to rotate. The driving motor is installed at the bottom of the installation inner shell and the output shaft of the driving motor passes through the installation inner shell from bottom to top and then is connected to the rotating cylinder. A temperature sensing probe is arranged at the bottom of the installation inner shell; the temperature sensing probe is used to detect the temperature of the rotating cylinder.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0040] Please refer to Figures 1-4, A milk warmer temperature sensing system, including a milk warmer main body 1 and a milk bottle follower 2. The milk warmer main body 1 has a first controller 11 and a first wireless signal transmission module 12. The milk bottle follower 2 is correspondingly installed on the milk bottle 100 driven by the milk warmer main body 1 for milk shaking. A temperature detection module 21 and a second wireless signal transmission module 22 are provided on the milk bottle follower 2. The temperature detection module 21 includes a temperature sensor 2101 for detecting the temperature of the milk bottle 100. The temperature detection signal detected by the temperature detection module 21 is wirelessly transmitted to the first controller 11 through the wireless connection between the second wireless signal transmission module 22 and the first wireless signal transmission module 12.

[0041] When the milk warmer main body 1 shakes the milk bottle 100, the milk bottle follower 2 correspondingly installed on the milk bottle 100 follows the milk bottle 100 to perform the milk shaking action, so that during the milk shaking process, the temperature sensor 2101 of the temperature detection module on the milk bottle follower 2 can detect the temperature of the milk bottle 100, so that the corresponding temperature detection can be carried out at a temperature sensing position closer to the temperature of the milk in the milk bottle, so that the first controller 11 of the milk warmer main body can receive a temperature detection signal closer to the temperature of the milk in the milk bottle, and thus make a more accurate temperature response control.

[0042] The first wireless signal transmission module 12 and the second wireless signal transmission module 22 can be wireless signal transmission modules of Bluetooth or other wireless transmission methods.

[0043] In some embodiments, the temperature sensor 2101 can be an NTC thermistor.

[0044] In some embodiments, the milk warmer main body 1 is a rotary milk shaker, and a rotary milk shaking drive mechanism is installed on the mounting frame 101 of the milk warmer main body.

[0045] Such as Figure 2 、 4 As shown, in some embodiments, the rotary milk shaking drive mechanism includes a milk shaking frame 13 and a drive motor 14 installed on the mounting frame 101 of the milk warmer main body. The milk shaking frame 13 can be used to place the milk bottle 100 that needs to be shaken. A vertically arranged milk shaking rotating shaft 16 is connected to the bottom of the milk shaking frame 13, and the rotating output shaft of the drive motor 14 is axially connected to the milk shaking rotating shaft 16, so that the rotation of the drive motor 14 can drive the milk shaking frame 13 to rotate at the same time, that is, the milk shaking frame 13 or the milk shaking rotating shaft 16 is rotatably connected to the mounting frame 101.

[0046] In some embodiments, an electric control milk warming mechanism 15 for heating the milk bottle 100 is provided on the milk warmer main body 1, and the electric heating element of the electric control milk warming mechanism 15 is electrically connected to the first controller 11. Control the heating of the milk bottle to achieve the effect of heat conduction and milk warming.

[0047] After receiving the temperature detection signal detected by the temperature sensor 2101, the first controller 11 can control the turning on / off of heating of the electric milk warming mechanism 15 according to the temperature information, and / or control the heating temperature. For example, it controls the electric heating element to be powered on for heating or powered off to stop heating, and controls the change of the heating power of the electric heating element.

[0048] Such as Figure 2 、 4 As shown, in some embodiments, the electric milk warming mechanism 15 includes a fan 151, a wind guide duct 152, and the above-mentioned electric heating element 153. The wind guide duct 152 guides the wind blown by the fan 151 to the rotatable milk shaking rack 13 or to the feeding bottle 100 through the openings on the milk shaking rack 13; the electric heating element 153 is used to heat the gas passing through the wind guide duct 152, so that the wind sent to the milk shaking rack 13 or the feeding bottle 100 is hot air, thereby performing the milk warming action.

[0049] In some embodiments, the electric heating element 153 is a PTC electric heating element installed in the wind guide duct 152.

[0050] In this embodiment, the feeding bottle follower 2 is detachably installed on the feeding bottle 100. Through the detachable design, the feeding bottle follower 2 can be more conveniently replaced, repaired, and reconfigured.

[0051] In some embodiments, the feeding bottle follower 2 is a cap-shaped feeding bottle follower 2a detachably installed on the mouth of the feeding bottle.

[0052] In some embodiments, the cap-shaped feeding bottle follower 2a includes a top cover 201. An elastic mounting skirt 202 is formed on the top cover 201. The mounting skirt 202 forms a sleeve on the outer side of the mouth of the feeding bottle, and the top cover 201 forms a cover on the mouth of the feeding bottle; the temperature sensor 2101 is installed on the top cover 201; when the top cover 201 covers the mouth of the feeding bottle, the temperature sensor 2101 senses the temperature at the mouth of the feeding bottle or enters the feeding bottle from the mouth of the feeding bottle. Through the elastic design of the expansion / tightening of the mounting skirt 202, the mounting skirt 202 can be sleeved on feeding bottles with different caliber sizes, and the applicability is better.

[0053] In some embodiments, the top cover 201 can be a top cover with tensile elasticity, so that it can better adapt to feeding bottles with different caliber sizes.

[0054] In some embodiments, anti-slip elastic claws 203 are formed on one side of the installation skirt 202 corresponding to the bottle mouth of the milk bottle. When the cap-shaped milk bottle follower 2a is installed on a smooth bottle mouth, the installation skirt 202 can form a tighter elastic sleeve on the outer side of the bottle mouth of the milk bottle through the anti-slip elastic claws 203, so that the top cover 201 is not easily separated from the milk bottle; when the cap-shaped milk bottle follower 2a is installed on a bottle mouth with an external thread, as Figure 2 shown, the anti-slip elastic claws 203 are engaged with the external thread, so that the top cover is not easily separated from the milk bottle.

[0055] Without the need for special processing of traditional milk bottles, the cap-shaped milk bottle follower 2a has better applicability.

[0056] As Figure 2 、 3 shown, in some embodiments, an installation groove 204 is formed on one side of the top cover 201 corresponding to the bottle mouth of the milk bottle. A constricted edge 205 is formed on the edge of the notch of the installation groove 204, and the constricted edge 205 reduces the passing width of the notch of the installation groove 204.

[0057] An electrical box 206 is squeezed into the installation groove 204 from the constricted edge 205. The temperature detection module 21 and the first wireless signal transmission module 12 are arranged on the electrical box 206.

[0058] The temperature sensor 2101 can be installed inside the electrical box 206; it can be installed on the external through hole of the electrical box 206; or it can be installed outside the electrical box 206.

[0059] After the cap-shaped milk bottle follower 2a is installed on the milk bottle 100, the cap-shaped milk bottle follower 2a covers the bottle mouth of the milk bottle to form a closed space including the inner space of the milk bottle, and the temperature sensor 2101 can detect the temperature at a position closer to the temperature of the milk in the milk bottle.

[0060] When the temperature sensor 2101 is installed on the external through hole of the electrical box 206 or outside the electrical box 206, the temperature sensor 2101 detects the temperature in the closed space correspondingly.

[0061] In this embodiment, the milk bottle follower 2 is a base-shaped milk bottle follower 2b installed on the bottom of the milk bottle.

[0062] In some embodiments, the base-shaped milk bottle follower 2b includes an installation base 207 connected to the bottom of the milk bottle; the temperature sensor 2101 is installed on the installation base 207, and senses the temperature outside the milk bottle or enters the milk bottle through an installation hole formed on the milk bottle to sense the temperature.

[0063] In some embodiments, a second power module 23 and a wireless charging receiving module 24 are further provided on the bottle follower 2. The bottle follower 2 can be charged by wireless charging.

[0064] In some embodiments, a wireless charging transmitting module 17 corresponding to the wireless charging receiving module 24 is installed on the mounting bracket 101 of the warmer main body. When milk shaking is performed, wireless charging can be correspondingly carried out for the bottle follower 2, ensuring that it can remain powered on for temperature detection and transmission of temperature detection signals in the case of milk shaking where wiring is not convenient. By setting corresponding wireless signal transmission and wireless charging in the milk shaking structure, when rotating milk shaking is performed, on the one hand, temperature detection can be carried out at a position on the bottle closer to the temperature of the milk in the bottle, making the temperature detection accurate; on the other hand, in the case of meeting the requirements of transmitting temperature detection signals and charging connection with the warmer main body during the milk shaking process, the situation of complex wiring structure can be effectively avoided.

[0065] In some embodiments, the warmer main body 1 is a rotating milk shaker, and the bottle follower 2 is a base-shaped bottle follower 2b installed on the bottom of the bottle. The rotation center line of the milk shaking rotating shaft 16 of the milk shaking frame is vertically arranged.

[0066] The wireless charging transmitting module 17 includes a transmitting coil 171 installed on the mounting bracket. The transmitting coil 171 is a hollow transmitting coil adapted to pass through the milk shaking rotating shaft 16; the transmitting coil 171 is located below the milk shaking frame 13 and close to the bottom of the milk shaking frame 13, and the milk shaking rotating shaft 16 correspondingly passes through the hollow gap of the transmitting coil 171 and is axially connected to the rotating output shaft of the driving motor.

[0067] The wireless charging receiving module 24 includes a receiving coil 241 installed on the mounting base 207 and corresponding to the transmitting coil 171.

[0068] After the bottle follower is set as the base-shaped bottle follower 2b and the transmitting coil 171 of the wireless charging transmitting module is designed as above, on the one hand, the wireless charging distance can be effectively shortened, and the wireless charging efficiency can be significantly improved; on the other hand, through the mutual cooperation of the hollow transmitting coil and the milk shaking rotating shaft, the overall space can be effectively reduced, which is more conducive to the miniaturization of the product.

[0069] In some embodiments, the electric milk warming mechanism forms a milk warming position on the warmer main body. The milk warming position corresponds to the position where the milk shaking frame is located. When the bottle is placed on the milk shaking frame, it is placed at the milk warming position. The bottle can be correspondingly heated and warmed by the electric milk warming mechanism at the milk warming position.

[0070] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
