Description

TECHNICAL FIELD

[0001] The utility model relates to milk shaker technical field especially, relate to a milk shaker of accurate temperature measurement. BACKGROUND

[0002] Milk powder is the main food of many infants, when feeding infants with milk powder, it is usually necessary to shake the milk powder evenly, but many milk powders melt slowly, and it needs long time to shake manually to make the milk powder completely dissolved in water. As a practical household appliance, milk shaker is welcomed by more and more families. Milk shaker can quickly mix milk powder and water by driving the milk shaking frame and the milk bottle to rotate through the motor, which can save time and prevent milk powder from caking and sticking to the wall.

[0003] Because the digestive system of infants is relatively fragile, the milk for feeding infants needs accurate temperature, so it is necessary to set a temperature measuring device on the milk shaker to measure the temperature of the liquid in the milk bottle. However, due to the compact structure of the milk shaker, the internal installation space is limited, it is difficult to install the temperature measuring device on the milk shaker, or the temperature measuring effect is not ideal after installation. The prior art sets a temperature measuring through hole in the center of the bottom of the milk shaking frame where the milk bottle is placed, and sets a temperature measuring sensor below the temperature measuring through hole to achieve good temperature measuring effect. However, the temperature measuring sensor will occupy the installation position of the motor, which makes the motor unable to be coaxially arranged with the milk shaking frame. In order to enable the motor to drive the milk shaking frame, it is necessary to add bearings, transmission wheels, belts and other components, which complicates the internal structure of the milk shaker, increases the weight and volume of the milk shaker, and brings inconvenience to use. In addition, a considerable part of the milk shakers on the market still do not have the temperature measuring function. SUMMARY

[0007] Further, the bottom of the milk shaking frame has at least two temperature measuring openings, which are uniformly distributed in the circumferential direction.

[0008] Further, the bottom of the milk shaking frame has a shielding part between the non-contact temperature measuring device and the milk bottle.

[0009] Further, the circumferential length of the temperature measuring opening is not less than 10 mm.

[0012] Further, the position detecting device and the non-contact temperature measuring device are electrically connected to the control device, the control device being configured to take the temperature of the milk bottle sensed by the non-contact temperature measuring device through the temperature measuring opening as a temperature control signal according to the position signal of the milk shaking frame obtained by the position detecting device, and discard the temperature of the shielding part sensed by the non-contact temperature measuring device.

[0013] Further, during the process that the milk shaking frame stops rotating, the control device is configured to position the temperature measuring opening directly above the non-contact temperature measuring device when the milk shaking frame completely stops rotating according to the position signal of the milk shaking frame obtained by the position detecting device.

For those of ordinary skill in the art, the specific meanings of the above terms in the present patent can be understood according to the specific circumstances.

[0028] Some embodiments of the present patent will be described in detail below with reference to the accompanying drawings. The features in the following embodiments can be combined with each other without conflict.

[0029] As Figures 1-5 shown, the present patent provides a precise temperature measuring milk shaker, which comprises a machine body 1, a milk shaking frame 2 arranged on the machine body, and a control device 3. The milk shaking frame 2 can rotate around a center axis A, and a milk shaking cavity 21 suitable for placing a milk bottle is formed inside the milk shaking frame 2.

[0030] The body 1 is provided with a non-contact temperature measuring device 4, which is arranged at a position deviating from the central axis A. The bottom of the milk shaking frame 2 has at least one temperature measuring opening 22, which is arranged at a position corresponding to the non-contact temperature measuring device 4, specifically, the temperature measuring opening 22 is arranged at the bottom of the milk shaking frame 2 deviating from the central axis A, the eccentricity of the non-contact temperature measuring device 4 relative to the central axis A is d1, the eccentricity of the temperature measuring opening 22 relative to the central axis A is d2, d1 and d2 are substantially equal, so that the temperature measuring opening 22 can be above the temperature measuring probe 4 when the milk shaking frame 2 rotates, so that the non-contact temperature measuring device 4 can perceive the temperature of the milk bottle in the milk shaking cavity 21 through the temperature measuring opening 22. The eccentricity of the non-contact temperature measuring device 4 relative to the central axis A should refer to the common size of the milk bottle, and should not be too large, so as to avoid that when the milk bottle is placed in the milk shaking frame 2, the position of the non-contact temperature measuring device 4 exceeds the periphery of the milk bottle, resulting in that the temperature measurement cannot be realized; preferably, the eccentricity can take a smaller value, so that the structure of the milk shaker is as compact as possible.

[0031] As shown in Figures 3-5 , as a preferred, the temperature measuring opening 22 is provided with at least two on the milk shaking frame 2, in an embodiment, the temperature measuring opening 22 is provided with 3; and these temperature measuring openings 22 are uniformly distributed in the circumferential direction. The multiple uniformly distributed temperature measuring openings 22 make the frequency of the non-contact temperature measuring device 4 perceiving the temperature through the temperature measuring opening 22 higher when the milk shaking frame 2 rotates, so that the temperature measuring effect of the temperature measuring device is more accurate and sensitive. The circumferential length of the temperature measuring opening 22 is preferably not less than 10mm, so as to ensure that the temperature measuring opening 22 can stay above the non-contact temperature measuring device 3 for a period of time, so that the non-contact temperature measuring device 4 has enough reaction time to complete the temperature perception process. Since the milk shaking frame 2 makes circular motion, the temperature measuring opening 22 is preferably arranged as a fan-shaped hole, the arc length of the fan-shaped hole is not less than 10mm; the non-contact temperature measuring device 4 has a certain size, if the radial width of the temperature measuring opening 22 is too narrow, it may cause that the non-contact temperature measuring device 4 cannot perceive the temperature through the temperature measuring opening 3, thereby adversely affecting the temperature measuring effect, therefore, the radial width of the temperature measuring opening 22 can be preferably set to not less than 5.0mm, so that the temperature measuring effect is more stable and reliable.

[0032] As shown in Figures 3-5 , the bottom of the milk shaking frame also has a shielding part 23, specifically, the non-contact temperature measuring device 4 intermittently perceives the temperature of the milk bottle, and in one rotation period of the milk shaking frame 2, the shielding part 23 and the temperature measuring opening 22 take turns above the non-contact temperature measuring device 4; when the shielding part 23 follows the milk shaking frame 2 to rotate to the position above the non-contact temperature measuring device 4, the shielding part 23 is between the non-contact temperature measuring device 4 and the milk bottle, at this time the non-contact temperature measuring device 4 measures the temperature of the shielding part 23 instead of the temperature of the milk bottle.

[0033] like Figures 1-4 As shown, in order to meet the needs of use, the milk shaker should have heat preservation and heating functions, so a device for heating the milk bottle needs to be installed on the milk shaker. As a preferred option, a hot air generator 6 is installed inside the body 1, and multiple side wall openings 24 are provided on the side of the milk shaker frame 2. The hot air generator 6 can generate hot air that passes through the side wall openings 24 to heat the milk bottle in the milk shaker chamber 21.

[0034] like Figure 3 and Figure 4 As shown, the milk shaker also includes a position detection device 5 for detecting the position of the milk shaker frame. The position detection device 5 includes a Hall element 51 and a magnet 52. The magnet 52 is disposed on the milk shaker frame 2, and the Hall element 51 is disposed on the body. Specifically, the magnet 52 is disposed at the bottom of the milk shaker frame 2, and the Hall element 51 can be disposed at any suitable position with the same eccentricity between the magnet 52 and the central axis A.

[0035] like Figures 3-5 As shown, both the position detection device 5 and the non-contact temperature measuring device 4 are electrically connected to the control device 3, enabling the control device 3 to exchange electrical signals with the position detection device 5 and the non-contact temperature measuring device 4. The control device 3 is equipped with a microcontroller program. Based on the position signal of the shaking frame 2 obtained by the position detection device 5, it uses the bottle temperature sensed by the non-contact temperature measuring device 4 through the temperature measuring opening 22 as the temperature control signal, and discards the temperature signal sensed by the shielding part 23. Specifically, the magnet 52 is positioned at the bottom of the shaking frame 2 corresponding to the shielding part 23. When the shaking frame 2 rotates to a position where the shielding part 23 is above the non-contact temperature measuring device 4, the position detection device 5 is activated to generate a signal, which is transmitted to the control device 3. The microcontroller program in the control device 3 discards the temperature signal sensed by the non-contact temperature measuring device 4 at this time. When the shaking frame 2 rotates to a position where the temperature measuring opening 22 is directly above the non-contact temperature measuring device 4, the Hall element 51 does not generate the Hall effect, and the non-contact temperature measuring device 4 senses and outputs the bottle temperature. By setting up the position detection device 5 and the control device 3 in this way, useless temperature signals can be removed, and the non-contact temperature measuring device 4 can output accurate temperature control signals.

[0036] like Figures 2-4As shown, if the shield 23 is above the non-contact temperature measuring device 4 when the shaking frame 2 has completely stopped rotating, the non-contact temperature measuring device 4 will measure the temperature of the shield 23 instead of the bottle, resulting in inaccurate temperature measurement. Simultaneously, due to the presence of the hot air generator 6, if the bottle heating function is on, the shaking frame 2 and the shield 23 will continue to be heated, interfering with the temperature measurement of the non-contact temperature measuring device 4. Therefore, during the process of the shaking frame 2 stopping rotating, the microcontroller program of the control device 3 will completely brake the shaking frame 2 when the temperature measuring opening 22 rotates to a position suitable for the non-contact temperature measuring device 4 (i.e., the position where the non-contact temperature measuring device 4 can sense the bottle temperature through the temperature measuring opening 22). This ensures that after the shaking process is complete, the non-contact temperature measuring device 4 can accurately measure the bottle temperature and output a signal.

[0037] like Figure 3 and Figure 4 As shown, methods for non-contact temperature measurement of target objects include infrared temperature measurement, laser temperature measurement, and thermal imaging temperature measurement, among which infrared temperature measurement is a commonly used and effective method. In this embodiment, the non-contact temperature measurement device 4 has an infrared signal sensor 41.

[0038] like Figure 3 and Figure 4 As shown, if the distance between the non-contact temperature measuring device 4 and the bottom of the milk shaker 2 is too far, the infrared signal sensor 41 may not be able to stably receive the infrared signal from the bottle, resulting in unstable temperature measurement. Therefore, the distance between the non-contact temperature measuring device 4 and the bottom of the milk shaker 2 is preferably set to no more than 2.0 cm.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
