Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products, and more specifically to a breast shaker. Background Technology

[0002] In some related technologies, waterless bottle warmers utilize hot air for heating. The hot air heats the bottle, warming the refrigerated breast milk or prepared formula inside, thus achieving the goal of warming the milk. Furthermore, a rack and pinion mechanism or belt rotates the bottle basket in a reciprocating or circumferential motion to ensure the formula is evenly mixed and to prevent clumping or pelleting.

[0003] Most existing baby shakers use contact-type NTC temperature sensors to detect the temperature of the baby bottle. However, the reciprocating rotation of the baby bottle causes friction between the contact-type NTC temperature sensor and the bottle, resulting in inaccurate readings. To avoid friction between the contact-type NTC temperature sensor and the baby bottle, some baby shakers use an open-hole infrared non-contact temperature sensor. This avoids friction caused by contact while still measuring the temperature. However, the through-hole for infrared rays to pass through can cause the temperature measuring area inside the shaking basket to fail to seal, resulting in a loss of the internal sealing structure. Furthermore, the infrared non-contact temperature sensor is easily affected by external airflow and liquid interference, leading to a decrease in temperature measurement accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a milk shaker that keeps the temperature measuring area relatively sealed and has high temperature measurement accuracy.

[0005] The technical solution of this utility model is to provide a milk shaker with the following structure, including a base and a heating cup rotatably connected to the base. An infrared sensor is fixedly connected inside the base. The bottom of the heating cup is provided with a through hole, and a heat-conducting cover is fitted inside the through hole. The heat-conducting cover is arranged opposite to the infrared sensor.

[0006] As an improvement of this utility model, the heat-conducting cover is slidably connected inside the through hole.

[0007] As an improvement of this utility model, an elastic element is provided between the heat-conducting cover and the heating cup.

[0008] As an improvement of this utility model, a fixed or detachable fixed seat is fixedly connected inside the through hole, the heat-conducting cover is slidably connected inside the fixed seat, and an elastic element is provided between the heat-conducting cover and the fixed seat.

[0009] As an improvement of this utility model, the heat-conducting cover is provided with a first folded edge that is axially limited by the fixed seat, and the other side of the first folded edge is in contact with the elastic element.

[0010] As an improvement of this utility model, the first folded edge extends to have a second folded edge that is radially limited by the elastic element.

[0011] As an improvement of this utility model, the second folded edge is provided with a gap between it and the inner wall of the fixing seat.

[0012] As an improvement of this utility model, the upper part of the fixed base is provided with a windproof ring.

[0013] As an improvement of this utility model, the fixing base is integrally molded from rubber or silicone.

[0014] As an improvement of this utility model, a sensor base is fixedly connected inside the base, and the infrared sensor is disposed on the sensor base.

[0015] With the above structure, the baby shaker of this invention has the following advantages compared with the prior art: By setting a heat-conducting cover, the through hole can be blocked, and the heat-conducting cover can directly contact the baby bottle in the heating cup for heat conduction. The heat-conducting cover can always fit with the baby bottle as it rotates, and can be directly positively correlated with the temperature of the baby bottle. There is no friction caused by relative rotation, so direct heat transfer can be carried out. The infrared sensor set up opposite can directly obtain the temperature of the heat-conducting cover to achieve accurate measurement. At this time, the heat-conducting cover blocks the through hole, and the temperature measuring area is relatively sealed, avoiding airflow and liquid interference with the infrared sensor, so that the infrared sensor can accurately measure the temperature.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] See appendix Figure 1 - Appendix Figure 3A milk shaker includes a base 100 and a heating cup 200 rotatably connected to the base 100. An infrared sensor 110 is fixedly connected inside the base 100, and a sensor base 120100 can be fixedly connected inside the base 100. The infrared sensor 110 is disposed on the sensor base 120100, providing structural stability. A through hole 210 is provided at the bottom of the heating cup 200, and a heat-conducting cover 300 fits inside the through hole 210. The heat-conducting cover 300 is positioned opposite to the infrared sensor 110, and the heat-conducting cover 300 can block the through hole. The through hole 210 is blocked, and the heat-conducting cover 300 can directly contact the bottle inside the heating cup 200 to conduct heat. The heat-conducting cover 300 can always fit with the bottle as it rotates, and can be directly positively correlated with the bottle temperature. There is no friction caused by relative rotation, so direct heat transfer can be carried out. The infrared sensor 110 can directly obtain the temperature of the heat-conducting cover 300 to achieve accurate measurement. At this time, the heat-conducting cover 300 blocks the through hole 210, and the temperature measuring area is relatively sealed, avoiding airflow and liquid interference with the infrared sensor 110, so that the infrared sensor 110 can accurately measure the temperature.

[0022] See appendix Figure 3 The heat-conducting cover 300 is flat-bottomed and tapers downwards along a certain arc to form a bowl shape. The flat bottom can better contact and conduct heat with various types of baby bottles, and the back of the flat bottom is easier to be positioned relative to the infrared sensor 110. The infrared sensor 110 can more accurately and quickly measure the temperature of the back of the flat bottom. The bottle warmer can determine the model parameters of the baby bottle by obtaining the temperature rise parameters of the baby bottle within a predetermined time period. These model parameters include the capacity, material, thickness and other specifications of the baby bottle. Based on the model parameters of the baby bottle, the pre-stored corresponding relationship table is consulted to determine the working parameters of the hot air component. In this way, the heating program can be selected for baby bottles with different specifications such as capacity, material, and thickness. The corresponding heat-conducting cover 300 can be made of a single or composite material with high thermal conductivity, such as metal or graphene. Ignoring a certain error, it can directly represent the temperature of the bottom of the baby bottle. By using the pre-set model parameters of the baby bottle, the working parameters of the hot air component can be determined directly based on the data measured by the infrared sensor 110. In addition, the heat-conducting cover 300 keeps the temperature measuring area relatively sealed, avoiding airflow and liquid interference with the infrared sensor 110, so that the infrared sensor 110 can accurately measure the temperature. Compared with direct measurement, it can more accurately determine the model parameters of the baby bottle.

[0023] To further refine the heating parameters, a correspondence table can be established between the temperatures of the heat-conducting cap 300 at different real-time temperatures at the bottom of the bottle. Experiments show that the correspondence table for the heat-conducting cap 300 is most accurate when using copper-aluminum composite materials and copper materials, as the thermal hysteresis is low. The correspondence table between the bottle and the temperature of the heat-conducting cap 300 can be integrated into the bottle's model parameters to directly determine the operating parameters of the hot air assembly, resulting in efficient and rapid heating. The structure of the heat-conducting cap 300 can eliminate most interference, obtaining an accurate temperature for the heat-conducting cap 300. Correspondingly, the temperature at the bottom of the bottle can be accurately obtained, allowing for a more accurate determination of the bottle's model parameters and further enhancing the efficiency and speed of heating.

[0024] Baby bottles are mostly made of materials such as glass, PP, PES, PPSU, and silicone, which have low thermal conductivity. During the heating process, the surface temperature of the bottle is higher than the inner wall temperature. That is, in the actual heating process, the heat-conducting cap 300 will heat up at a rate higher than that of the liquid inside the bottle. In the actual heating process, the outlet temperature of the hot air component is the highest, followed by the internal temperature, and then the surface temperature of the bottle. By measuring the surface temperature of the bottle through the heat-conducting cap 300 and the infrared sensor 110, a heating curve between the heat-conducting cap 300 and the liquid temperature can be directly established in the heating logic that measures the liquid temperature. Due to the large heating range and high rate of the heat-conducting cap 300, the error can be reduced to a large extent, making the heating curve between the heat-conducting cap 300 and the liquid temperature accurate, and enabling efficient and fast heating.

[0025] The heat-conducting cover 300 is slidably connected within the through hole 210, providing a large non-contact space between the heat-conducting cover 300 and the infrared sensor, thus dynamically sealing the enclosed measurement area and preventing airflow and liquid interference with the infrared sensor 110. This allows the infrared sensor 110 to accurately measure the temperature. An elastic element 400 is provided between the heat-conducting cover 300 and the heating cup 200, ensuring sufficient contact between the heat-conducting cover 300 and the bottle, maintaining accurate temperature measurement.

[0026] See appendix Figure 3A fixing base 500 is fixedly connected inside the through hole 210, and the heat-conducting cover 300 is slidably connected inside the fixing base 500. An elastic element 400 is provided between the heat-conducting cover 300 and the fixing base 500. The fixing base 500 is an integral unit, which can achieve overall sealing and ensure that the temperature measuring area formed by the fixing base 500 and the heat-conducting cover 300 is not affected by external interference. The fixing base 500 can be made of heat-insulating material, which can be integrally molded from rubber or silicone. Further heat-insulating material can be provided between the fixing base 500 and the heating cup 200 to further improve the measurement accuracy. Alternatively, the fixing base 500 can be detachably connected inside the through hole 210, that is, the fixing base 500 and the heat-conducting cover 300 can be detached as a whole, which not only facilitates installation, but also facilitates maintenance and repair. A wind deflector ring is provided on the upper part of the fixing base 500. The wind deflector ring abuts against the baby bottle to further prevent the heat-conducting cover 300 from contacting hot air, so as to obtain the baby bottle temperature more accurately and directly.

[0027] See appendix Figure 3 The heat-conducting cover 300 is provided with a first folded edge 310 that is axially limited by the fixed base 500. The other side of the first folded edge 310 is in contact with the elastic member 400, providing a large force-bearing surface in contact with the elastic member 400, which makes the overall structure temperature reliable. The other side is axially limited by the fixed base 500, which can maintain stability after long-term and repeated contact with the baby bottle. The first folded edge 310 extends to a second folded edge 320 that is radially limited by the elastic member 400, which can be sleeved on the elastic member 400 to make the force more stable. The second folded edge 320 has a gap with the inner wall of the fixed base 500 to reduce friction interference and make the operation more stable.
