Description

Technical Field

[0001] The present invention relates to the technical field of portable cooling, and particularly to a portable summer cooling and refrigerating device and a summer-proof clothing. Background Art

[0002] At present, in response to the hot and high temperature in summer, there are several wearable summer-proof clothes (or called summer-proof clothing, portable air conditioners, etc.) in the domestic and foreign markets. Classified by the cooling method, the summer-proof clothes can generally be divided into forms such as ice bag cooling, water evaporation cooling, air compression cooling, fan cooling, air-cooling, and water circulation refrigeration. There are drawbacks in using the above cooling methods for summer-proof clothes;

[0003] 1) Ice bag cooling: Ice bag pockets are added (sewn) in the lining of the clothes. In a high-temperature environment, the ice bag is placed in the pocket of the clothes to use the ice for refrigeration. This kind of summer-proof clothing needs to pre-make the ice bag into ice in the refrigerator. When in use, the ice is placed in the clothes interlayer. Its existing disadvantages are: (a) It is troublesome and requires pre-making the refrigerant (ice) through the refrigerator; (b) Since the ice needs to be carried, the clothes are relatively heavy; (c) When the ice melts into water, it will lose the refrigeration effect as the temperature rises;

[0004] 2) Water evaporation cooling: This kind of summer-proof clothing uses special materials. First, it absorbs water, and then cools down by continuously evaporating the water absorbed by the fabric of the clothes. The existing disadvantages are: (a) Since there is water on the fabric, it will be damp and uncomfortable to wear; (b) The cooling effect is not ideal and cannot meet the requirement of reducing the temperature in a hot summer and high-temperature environment. Ideally, it can only reduce the temperature by no more than 5°C; (c) The duration is relatively short. When the water on the clothes fabric evaporates, water needs to be replenished in time;

[0005] 3) Air compression cooling: Compressed air is used to cool through a vortex tube. The advantages of vortex tube refrigeration are: no moving parts, high reliability, light weight, no refrigerant, etc. However, the disadvantages are also obvious: low refrigeration efficiency (the coefficient of performance (COP) is less than 0.1), relying on a high-noise and high-power air compressor, requiring connection to civil power supply and air compressor, inconvenient to move, and the activities are restricted;

[0006] 4) Fan cooling: By adding two fans on both sides of the back waist of the sunscreen clothing, the air flow between the cooling clothing and the body surface is used, and the air blown by the fans is used to cool down. Its disadvantage is that the cooling effect is average (ideally, no more than 5°C).

[0007] 5) Air-cooling: Such as cycling clothing, this kind of summer-proof clothing also uses the evaporation of water for refrigeration. Its advantage is that water is sufficient and suitable for cycling. The disadvantage is that it requires wind. If there is no speed and no wind, the refrigeration effect is very poor;

[0008] 6) Water cycle refrigeration. This type of refrigeration clothing uses cold water driven by a pump to circulate inside the clothing for refrigeration. Its advantage is good effect, and its disadvantage is that the duration is not long, and the refrigeration effect is not good for a long time. Summary of the Invention

[0009] The object of the present invention is to overcome the defects existing in the prior art and provide a portable summer cooling device and summer-proof clothing, aiming to solve the problems of poor cooling effect, short cooling duration, large weight, not easy to carry, and high manufacturing cost existing in the summer-proof clothing in the prior art;

[0015] At least one air inlet communicating with the aerosolizer is opened in the sealed cavity, and a throttle member for restricting the flow rate of the aerosol of the aerosolizer is installed at the air inlet, so that the aerosol flows through the throttle channel of the throttle member, expands after entering the sealed cavity, evaporates under vacuum conditions, and continuously provides cooling conditions for the main body of the refrigeration device.

[0016] Further, the structure of the main body of the refrigeration device is a sheet-like structure, and its shape under the negative pressure of the sealed cavity maintains a flat shape to maintain the vacuum degree.

[0017] Further, a plurality of struts are installed at intervals in the sealed cavity, and the sealed cavity forms a vacuum chamber under the vacuum pumping of the vacuum pump, and the inner wall of the sealed cavity is supported by the struts, so that the vacuum chamber maintains its shape under vacuum.

[0018] Further, a conduit is connected between the aerosolizer and the air inlet, water molecule particles generated by the aerosolizer are fused with air in the conduit to form an aerosol, and the exhaust end of the conduit is connected and sealed with the sealed cavity through the throttle member.

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] See Figure 1 As shown;

[0041] Invent a portable summer cooling device, including: aerosolizer 1, main body of the cooling device 2, vacuum pump 3;

[0042] The aerosolizer 1 is used to provide aerosol agent. Specifically, the aerosolizer 1 is a micro ultrasonic atomizer in the prior art. It stores a liquid medium inside, and the liquid medium is water or alcohol. An ultrasonic atomization sheet is installed at the top of the micro atomizer and is connected to the liquid medium through a cotton swab and absorbs the liquid medium. During operation, the ultrasonic microporous atomization sheet oscillates water molecules to form fine water mist of 3-5 microns and combines with air to form aerosol;

[0043] The vacuum pump 3 is a micro vacuum pump 3 in the prior art, and the main body 2 of the cooling device is evacuated by the vacuum pump 3;

[0044] The main body 2 of the cooling device has a sealed cavity inside. At least one air inlet 203 is opened in the sealed cavity. The aerosolizer 1 is communicated with and hermetically connected to the air inlet 203 of the sealed cavity through a conduit 4. The vacuum pump 3 is communicated with and hermetically connected to the air outlet 202 of the sealed cavity through a hose. The vacuum pump 3 is used to maintain the evacuation of the sealed cavity of the main body 2 of the cooling device to achieve negative pressure in the sealed cavity;

[0045] The air inlet 203 can be one or multiple. Preferably, there are two air inlets 203. The conduit 4 is a tee pipe. One path of the tee pipe is hermetically connected to the aerosolizer 1, and the other two paths are hermetically connected to the air inlets 203 of the sealed cavity. This embodiment only takes two air inlets 203 as an example, and is not limited to two;

[0046] Among them, referring to Figure 3 、 5 As shown, a throttle member 204 is installed at the air inlet 203 of the sealed cavity. The throttle member 204 is provided with a throttle channel 2041. Specifically, the throttle member 204 can adopt a needle structure in the prior art. The throttle channel 2041 is a channel formed by the circular needle hole extending along the axis direction, but it is not limited to the needle structure. The structure of the throttle member 204 can be a columnar body structure, and a circular or conical through hole is opened inside it. This through hole is the throttle channel 2041, as long as it can play a role in throttling expansion. When the throttle channel 2041 is a conical through hole, the opening diameter of the air inlet end of the throttle channel 2041 is larger than the opening diameter of the air outlet end;

[0047] In this structure, the conduit 4 is reduced in diameter through the throttle channel 2041, thereby restricting the flow rate entering the sealed cavity, realizing that the aerosol is throttled and expands after entering the sealed cavity. At the same time, it also plays a role in maintaining the vacuum degree of the sealed cavity, continuously providing refrigeration conditions for the main body 2 of the refrigeration device. In addition, the aerosol evaporates under vacuum conditions, which is more conducive to the refrigeration of the main body 2 of the refrigeration device. Furthermore, the portable summer cooling refrigeration device utilizes the aerosol to pass through the sealed cavity of the main body 2 of the refrigeration device and complete evaporation and heat absorption under the action of vacuum, achieving the purpose of cooling down the main body 2 of the refrigeration device;

[0048] Referring to Figure 1 、 3 As shown;

[0049] Preferably, the structure of the main body 2 of the refrigeration device is a sheet-like structure, and its shape under the negative pressure of the sealed cavity maintains the vacuum degree in a flat shape.

[0050] Specifically, the overall shape of the main body 2 of the refrigeration device projected on the horizontal plane is circular, oval, square or other polygons that can be widely adapted to the body area of the human body. And the structure of the main body 2 of the refrigeration device maintains the vacuum degree in a flat shape under the negative pressure of the sealed cavity, so that the main body 2 of the refrigeration device can keep providing cold in the form of a surface to cool the human body. At the same time, it can also fit well with the human body surface for use;

[0051] The material of the main body 2 of the refrigeration device is made of metal material aluminum, which can quickly transfer cold through the aluminum material. The wall thickness of the main body 2 of the refrigeration device is 0.2 - 2 mm, and preferably the wall thickness of the main body 2 of the refrigeration device is 0.5 mm. Hanging holes 205 through which straps can be threaded are provided on both sides of the main body 2 of the refrigeration device, and the main body 2 of the refrigeration device is fixed to the front chest or back of the human body through the straps;

[0052] See Figure 2 as shown;

[0053] Preferably, one end of the main body 2 of the refrigeration device is provided with an air inlet 203 along the direction of its shape length axis, and the other end is provided with an air outlet 202.

[0054] Specifically, along the direction of its shape long axis (more specifically, when the main body 2 of the refrigeration device is circular, it can be the direction of the same diameter of the circular structure, and when the main body 2 of the refrigeration device is elliptical, it can be the direction of the long axis of the ellipse) of the main body 2 of the refrigeration device, an air inlet 203 is provided at one end of the main body 2 of the refrigeration device, and an air outlet 202 is provided at the other end, so that the air flow enters from the air inlet 203 and exits from the air outlet 202 and flows through the entire closed cavity;

[0055] Among them, one end of the main body 2 of the refrigeration device is communicated with a vacuum pump 3 through the air outlet 202, and the other end is communicated with a conduit 4 through two air inlets 203, and a throttle member 204 is hermetically connected to the air inlet 203, and the air inlet end of the throttle member 204 is hermetically connected to the exhaust end of the conduit 4;

[0056] In this structure, by providing an air outlet 202 and an air inlet 203 at both ends of the main body 2 of the refrigeration device, after the aerosol enters the closed cavity through the throttle member 204, the air flow enters from the air inlet 203, exits from the air outlet 202 and flows through the entire closed cavity, ensuring the refrigeration effectiveness of the entire refrigeration area of the main body 2 of the refrigeration device and avoiding the phenomenon of local refrigeration ineffectiveness caused by the air flow not flowing through;

[0057] See Figure 2 and 3 as shown;

[0058] In a preferred embodiment, a plurality of struts 201 are installed at intervals in the closed cavity. The closed cavity forms a vacuum cavity under the vacuum pumping of the vacuum pump 3 and the inner wall of the closed cavity is supported by the struts 201, so that the vacuum cavity maintains its shape under vacuum.

[0059] Specifically, a plurality of struts 201 are arranged at intervals within the sealed cavity. The struts 201 are made of lightweight, non-toxic, and hard materials such as plastics and woods in the prior art. The sealed cavity is supported and protected by the struts 201 to prevent the opposite inner walls of the sealed cavity from coming into contact. In this way, when under vacuum, the shape of the vacuum cavity formed by the sealed cavity is protected from being flattened by the atmospheric pressure, maintaining the form of the vacuum cavity, thereby maintaining the vacuum degree within the vacuum cavity. This enables the aerosol to pass through the vacuum cavity under the action of vacuum and complete evaporation and heat absorption, playing a role in refrigeration and cooling.

[0060] See Figure 1 , 2 shown

[0061] A conduit 4 is connected between the aerosolizer 1 and the air inlet 203. The water molecule particles generated by the aerosolizer 1 are combined with air in the conduit 4 to form an aerosol. The exhaust end of the conduit 4 is connected and sealed to the sealed cavity through a throttle member 204.

[0062] Specifically, the aerosolizer 1 and the main body 2 of the refrigeration device are connected by a conduit 4. The water molecule particles generated by the aerosolizer 1 are combined with air in the conduit 4 to form an aerosol. The exhaust end of the conduit 4 is connected and sealed to the sealed cavity through a throttle member 204. The throttle member 204 is provided with a throttle channel 2041. The aerosol enters the sealed cavity through the throttle channel 2041. The throttle channel 2041 is a circular or polygonal through-hole, and it can play a role in throttling expansion (that is, the diameter of the throttle channel 2041 is not greater than the diameter of the conduit 4). In a preferred embodiment, the throttle channel 2041 is a circular through-hole, with a diameter range of 0.1 - 2 mm, and the more preferred point values of the diameter are 0.3 or 0.4;

[0063] The following Table 1 gives the refrigeration performance test data of the main body 2 of the refrigeration device with throttle channels 2041 of different diameters, taking the diameters of the throttle channels 2041 as 0.1 mm, 0.3 mm, and 0.4 mm as examples;

[0064]

[0065]

[0066] See Figure 1 shown;

[0067] In a preferred embodiment, the portable summer cooling and refrigeration device further includes a mobile power source 5 capable of providing electric energy. The mobile power source 5 is electrically connected to the aerosolizer 1 and the vacuum pump 3.

[0068] Specifically, for convenient carrying, the mobile power source 5 is a low-voltage safe lithium battery that can be charged and is below 24V. The lithium battery is electrically connected to the aerosolizer 1 and the vacuum pump 3 through cables.

[0069] In some embodiments, a summer-proof clothing is further provided. The summer-proof clothing includes a main body of the summer-proof clothing, and the above-mentioned portable summer-proof refrigeration device is installed on the main body of the summer-proof clothing through straps or sewing techniques, so that the summer-proof clothing has the same beneficial effects as the portable summer-proof refrigeration device, which will not be elaborated one by one here;

[0070] In the above technical solution, a portable summer-proof refrigeration device provided by the present invention has the following working principle:

[0071] First of all, the atomizer 1 is started. The liquid medium in the atomizer 1 forms tiny water molecule particles (about 3-5 microns) through the oscillation of the ultrasonic atomization sheet and is atomized to form an aerosol. At the same time, the vacuum pump 3 works, and the aerosol flows through the conduit 4 and the throttle member 204 into the sealed cavity of the refrigeration device main body 2. When the aerosol enters the sealed cavity, it flows through the throttle member 204. Since the aerosol suddenly passes through the narrow throttle channel 2041 of the throttle member 204, gas compression will occur. Subsequently, after entering the vacuum sealed cavity, it will expand rapidly. During the expansion process, the air will absorb heat (the gas throttling expansion process). At the same time, the water in the aerosol will evaporate faster under the action of the vacuum sealed cavity and absorb heat. The water in the air changes from liquid to gas and absorbs a large amount of latent heat of vaporization, thus producing a refrigeration and cooling effect. During this process, the large amount of heat absorbed by the aerosol in the sealed cavity will cause the temperature of the refrigeration device main body 2 to drop. Subsequently, the gas is discharged into the atmosphere through the vacuum pump 3 to complete the refrigeration process;

[0072] In the above technical solution, a portable summer-proof refrigeration device provided by the present invention;

[0073] Beneficial effects:

[0074] 1) Higher cooling efficiency and better effect, up to 15°C at most;

[0075] 2) Do not need to carry large equipment and a large amount of water for circulation, light weight, portable and easier to carry;

[0076] 3) Long cooling duration, using a large-capacity lithium battery, can continuously cool for more than 5 hours;

[0077] 4) Simple structure and low manufacturing cost.

[0078] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
