[0027] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.
[0028] like Figures 1 to 8 A milk cabinet shown in the figure comprises a milk cabinet shell 1, wherein a containing chamber 2 is provided in the milk cabinet shell 1, a refrigeration element 3 for converting high-pressure gas into cold air and hot air, a pressure pump 4 connected to the refrigeration element 3, and a storage battery 5 for providing power to the pressure pump 4 are provided on the outer wall of the milk cabinet shell 1, a high-pressure gas delivery pipe 6 is provided between the refrigeration element 3 and the pressure pump 4, and a first guide portion 7 for releasing cold air into the containing chamber 2 and a second guide portion 8 for discharging hot air to the external environment are provided on the refrigeration element 3;
[0029] The utility model discloses a milk cabinet, which is provided with a pressure pump and a refrigeration component connected to the pressure pump on the outer side wall of a shell of the milk cabinet, so that the refrigeration component obtains high-pressure gas from the pressure pump, and the high-pressure gas generates a vortex effect in the refrigeration component to be converted into cold air and hot air, and the hot air is discharged to the external environment through a second guide part, and the cold air is released to a containing cavity through a first guide part, so as to maintain a low-temperature environment in the containing cavity. A battery is also provided at the bottom of the shell of the milk cabinet to provide a reserve power source for the pressure pump. When the external environment is powered off, the battery can provide an independent power source for the pressure pump, which is conducive to the pressure pump providing a stable high-pressure gas for the refrigeration component, and effectively solves the problem that the refrigeration system in the existing milk cabinet cannot be cooled normally due to a malfunction or power outage, resulting in an increase in the temperature of the internal space of the milk cabinet and easy deterioration of dairy products and milk.
[0030] Furthermore, the refrigeration component 3 is a vortex tube.
[0031] Furthermore, by injecting high-pressure gas into the refrigeration component 3, a vortex effect occurs in the high-pressure gas in the refrigeration component 3. At this time, cold air will be ejected from one end of the refrigeration component 3, and hot air will be ejected from the other end of the refrigeration component 3. Working principle: after the high-pressure gas enters the refrigeration component 3, it continues to expand and accelerate, enters the circular refrigeration component 3 along the tangential direction at the speed of sound, and diffuses along the caliber of the inner wall of the refrigeration component 3 to form a high-speed rotating vortex. At this time, the high-pressure gas is divided into two airflows, one is a cold airflow close to the central axis of the refrigeration component 3, and the angular velocity of the cold airflow is the largest, and the other is a hot airflow close to the inner wall of the refrigeration component 3, and the rotation angle of the hot airflow is relatively low. Due to the different angular velocities, the cold airflow and the hot airflow rub against each other, thereby causing the high-speed rotating cold airflow in the inner circle to be driven by friction. The hot air flow in the outer circle rotates at a low speed, and the internal energy of the cold air flow in the inner circle is continuously converted into rotational kinetic energy. Since the internal energy of the cold air flow in the inner circle is continuously reduced, the temperature is relatively low. Correspondingly, the hot air flow in the outer circle continuously obtains kinetic energy due to friction to maintain rotation, and the internal energy is continuously increased, resulting in an increase in temperature. At this time, a lower-temperature inner circle cold air flow and a higher-temperature outer circle hot air flow are formed in the refrigeration component 3, and at the same time diffuse toward the outlet end with a conical plug. When reaching the outlet, the hot air flow is discharged from the gap at the edge of the conical plug, while the lower-temperature inner circle cold air flow is blocked by the conical plug. Since the cold air flow cannot be discharged and accumulates, the pressure increases, and it is squeezed out from the cold air outlet in the opposite direction, thereby realizing the separation of the high-pressure gas into two gases, cold air and hot air.
[0032] Furthermore, the refrigeration unit 3 is detachably connected to the milk cabinet housing 1 .
[0033] Furthermore, the second air guide portion 8 is detachably connected to the milk cabinet housing 1 .
[0034] Furthermore, the high-pressure gas delivery pipe 6 is detachably connected to the milk cabinet housing 1 .
[0035] Furthermore, the refrigeration component 3 is detachably connected to the first air guide portion 7 and the second air guide portion 8 respectively.
[0036] like Figures 1 to 8 The refrigeration component 3 shown includes a refrigeration pipe 31, a high-pressure gas input part 32 connected to the refrigeration pipe 31, a cold air output part 33 and a hot air output part 34 respectively located at both ends of the refrigeration pipe 31, the high-pressure gas delivery pipe 6 is connected to the high-pressure gas input part 32, the cold air output part 33 is connected to the first guide part 7, and the hot air output part 34 is connected to the second guide part 8;
[0037] Furthermore, a high-pressure gas input portion 32 connected to the high-pressure gas delivery pipe 6 is provided so that the high-pressure gas can smoothly enter the interior of the refrigeration pipe 31 to provide power for the refrigeration pipe 31 to achieve the cooling function.
[0038] Furthermore, by providing the refrigeration pipe fitting 31, after the high-pressure gas enters the refrigeration pipe fitting 31, a vortex effect occurs inside the refrigeration pipe fitting 31, and the high-pressure gas is converted into cold air and hot air inside the refrigeration pipe fitting 31, and the cold air and hot air are discharged from two opposite directions.
[0039] Furthermore, the cold air output part 33 is located at one end of the refrigeration pipe 31. Through the vortex effect, the high-pressure gas forms cold air with a lower temperature in the refrigeration pipe 31, and the cold air is guided into the accommodating cavity 2 through the first guide part 7, so that the inside of the milk cabinet shell 1 maintains a low temperature environment.
[0040] Furthermore, the hot gas output part 34 is located at the other end of the refrigeration pipe 31. Through the vortex effect, the high-pressure gas forms hot gas with a higher temperature in the refrigeration pipe 31, and the hot gas is guided to the external environment through the second guide part 8 to achieve a heat dissipation effect.
[0041] like Figures 1 to 8 The inner wall of the refrigeration pipe 31 is provided with threads 311 distributed along the circumference of the refrigeration pipe 31;
[0042] Furthermore, by providing a thread 311 on the inner wall of the refrigeration pipe 31, it is helpful to increase the surface area of the high-pressure gas in contact with the inner wall of the refrigeration pipe 31. Due to the increase in surface area, the high-pressure gas can be more fully converted into hot air and cold air, effectively improving the refrigeration efficiency.
[0043] Furthermore, by providing a thread 311 on the inner wall of the refrigeration pipe 31, the existence of the thread 311 effectively increases the vortex effect in the refrigeration pipe 31, so that the cold air flow and the hot air flow rub more fully in the refrigeration pipe 31, thereby improving the energy transfer efficiency, effectively accelerating the cooling speed of the accommodating chamber 2, and realizing a more efficient refrigeration process.
[0044] like Figures 1 to 8 The high-pressure gas input part 32 is located on the refrigeration pipe 31 near one end of the cold gas output part 33 and is arranged around the outer peripheral side wall of the refrigeration pipe 31. The high-pressure gas input part 32 is provided with a first opening 321 connected to the high-pressure gas delivery pipe 6. The refrigeration pipe 31 is provided with a plurality of guide holes 312 distributed at intervals along the circumference of the high-pressure gas input part 32.
[0045] Furthermore, by arranging a plurality of guide holes 312 on the refrigeration pipe 31 and distributed circumferentially along the high-pressure gas input part 32 and arranged at intervals, the high-pressure gas enters the interior of the refrigeration pipe 31 through the plurality of guide holes 312 and forms a vortex flow, which is beneficial for the high-pressure gas to rotate and mix inside the refrigeration pipe 31, thereby realizing an efficient vortex effect.
[0046] like Figures 1 to 8 The cold air output portion 33 shown in the figure is provided with a cold air output hole 331 communicating with the first air guide portion 7 at the center of the end surface of the cold air output portion 33 close to one end of the first air guide portion 7;
[0047] Furthermore, the cold air output hole 331 is located at the center of the cold air output part 33, and the position of the cold air output hole 331 corresponds to the position of the cold air flow with lower temperature close to the central axis in the refrigeration pipe 31, which is conducive to the cold air flow entering the first guide part 7 through the cold air output hole 331.
[0048] Furthermore, through the cold air output hole 331, the cold air output part 33 and the first air guide part 7 are connected, so that the cold air flow can directly enter the first air guide part 7 and obtain further guidance and control there, which is beneficial to ensure that the cold air flow is distributed and transmitted at a suitable speed and direction, thereby effectively improving the cooling rate of the accommodating cavity 2.
[0049] like Figures 1 to 8 The hot air output portion 34 shown is located at one end of the refrigeration pipe 31 close to the second guide portion 8 and is provided with a protrusion 341 extending toward the cold air output portion 33, and a gap 342 for discharging hot air is provided between the protrusion 341 and the refrigeration pipe 31;
[0050] Optionally, the cross section of the protrusion 341 is trapezoidal.
[0051] Optionally, the cross section of the protrusion 341 is fan-shaped.
[0052] Furthermore, the protrusion 341 is a conical protrusion extending toward the cold air output portion 34 .
[0053] Furthermore, the gap 342 is located between the outer wall of the protrusion 341 and the inner wall of the refrigeration pipe 31. The gap 342 is distributed in a circular shape along the circumference of the inner wall of the refrigeration pipe 31, corresponding to the position of the hot air flow with a higher temperature. When the hot air in the refrigeration pipe 31 rotates along the vortex and approaches the hot air output part 34, the hot air flow is discharged through the gap 342, thereby separating the hot air and the cold air.
[0054] Optionally, the second guide portion 8 is connected to the hot air output portion 34 , and under the action of the second guide portion 8 , the hot air flow can be released to a suitable position.
[0055] like Figures 1 to 8 The refrigeration pipe 31, the high-pressure gas input part 32, the cold air output part 33 and the hot air output part 34 are integrally formed;
[0056] Optionally, the refrigeration pipe 31, high-pressure gas input part 32, cold air output part 33 and hot air output part 34 are detachably connected. The detachable connection makes the refrigeration component 3 easy to maintain. When some parts need to be replaced, specific parts can be replaced to save maintenance costs.
[0057] Furthermore, the refrigeration pipe 31, the high-pressure gas input part 32, the cold air output part 33 and the hot air output part 34 are integrally formed. The integrally formed setting can reduce the number of connecting joints and connecting parts between the components, so that the overall structure of the refrigeration component 3 is more compact; secondly, the integrally formed setting can reduce the possibility of leakage of the refrigeration component 3 and improve the sealing of the refrigeration component 3; finally, the integrally formed design can reduce potential failure points such as connection points and joints, effectively reduce the failure rate of the system, and improve the overall reliability and stability of the refrigeration component 3.
[0058] like Figures 1 to 8 The accommodating chamber 2 shown in the figure is provided with a supporting portion 21 for placing dairy products, and the first air guide portion 7 includes a ventilation plate 71 located above the supporting portion 21 and communicating with the accommodating chamber 2, and a cold air delivery pipe 72 connected to the refrigeration element 3 and communicating with the ventilation plate 71;
[0059] Furthermore, by arranging the ventilation plate 71 above the supporting portion 21, milk or dairy products are placed on the supporting portion 21, and cold air enters the accommodating chamber 2 through the ventilation plate 71, which is beneficial for the cold air to act on the milk and dairy products, keeping the milk and dairy products in a low temperature state, and preventing the milk and dairy products from spoiling due to the increase in temperature.
[0060] Furthermore, ventilation hole groups are evenly spaced on the ventilation plate 71, and cold air enters the accommodating cavity 2 through the ventilation hole groups, so that the cold air can be evenly distributed on the supporting portion 21, effectively preventing overcooling in certain areas, and effectively improving the insulation effect and quality of cold air on milk and dairy products.
[0061] like Figures 1 to 8 The high-pressure gas delivery pipe 6 shown is provided with a regulating valve 61 for controlling the flow rate of the high-pressure gas;
[0062] Furthermore, by setting a regulating valve 61 for controlling the high-pressure gas flow on the high-pressure gas delivery pipe 6, the high-pressure gas flow can be controlled. By rotating the regulating valve 61, the user can accurately control the high-pressure gas flow to meet the user's actual needs.
[0063] Furthermore, by setting a regulating valve 61 on the high-pressure gas delivery pipe 6, the high-pressure gas flow and pressure can be regulated. The regulating valve 61 can adjust the high-pressure gas flow and pressure to the required working range according to the actual needs of the user to ensure the normal operation of the system.
[0064] like Figures 1 to 8 The bottom of the milk cabinet housing 1 is also provided with a support portion 11 for fixing the position of the milk cabinet housing 1;
[0065] Furthermore, the support part 11 is located at the bottom of the milk cabinet shell 1 and is four bases symmetrically arranged along the four corners. The setting of the support part 11 can firmly fix the milk cabinet shell 1 on the ground, effectively ensuring that the milk cabinet shell 1 will not move or shake accidentally during use and maintain a stable position.
[0066] Furthermore, since the support portion 11 is composed of four symmetrically arranged bases, the four bases can evenly distribute the weight of the milk cabinet housing 1 and can reduce the direct pressure of the milk cabinet housing 1 on the ground, so that the ground is not easily damaged during long-term use.
[0067] Furthermore, four bases support the milk cabinet shell 1 so that there is a certain space between the ground and the bottom of the milk cabinet shell 1. The battery 5 and the pressure pump 4 can be installed in this space, which is conducive to saving space and making the overall structure more compact.
[0068] The implementation method of this embodiment is as follows:
[0069] A milk cabinet comprises a milk cabinet shell 1, a housing chamber 2 is arranged in the milk cabinet shell 1, a refrigeration element 3 for converting high-pressure gas into cold air and hot air, a pressure pump 4 connected to the refrigeration element 3, and a storage battery 5 for providing power to the pressure pump 4 are arranged on the outer wall of the milk cabinet shell 1, one end of the refrigeration element 3 is connected to a first guide part 7, and the other end of the refrigeration element 3 is connected to a second guide part 8. When the refrigeration system inside the milk cabinet fails, the user can start the pressure pump 4, and the pressure pump 4 can provide high-pressure gas to the refrigeration element 3. After the high-pressure gas enters the refrigeration element 3, a vortex effect occurs, and the high-pressure gas is converted into cold air and hot air. There are two air flows, cold air and hot air. The hot air is discharged to the external environment through the second guide part 8 to achieve the heat dissipation effect, and the cold air enters the accommodating chamber 2 through the first guide part 7 to achieve the cooling effect. When the external power is off, the user can also start the battery 5 to provide power for the pressure pump 4 to ensure that the pressure pump 4 can provide stable high-pressure gas for the refrigeration part 3, thereby maintaining the low-temperature environment in the accommodating chamber 2. This effectively solves the problem that the refrigeration system in the existing milk cabinet cannot be refrigerated normally due to failure or power outage, resulting in the temperature of the internal space of the milk cabinet rising, and dairy products and milk are easily spoiled.
[0070] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
