Description

Technical Field

[0001] The present invention relates to a cold air blower, in particular to a portable cold air blower with efficient water evaporation refrigeration, belonging to the household appliance field. Background Art

[0002] According to the statistical data of the World Health Organization and several international research institutions, due to extreme high temperature weather, the number of deaths caused by high temperature and diseases induced by high temperature globally averages hundreds of thousands per year. A large part of these unfortunate people belong to the economically disadvantaged population, and most of them are unable to afford the investment in air conditioners and electricity bills due to economic constraints and thus lose their lives. When hit by a heat wave, the temperature often reaches over 40°C, and the hot air blown by an electric fan cannot help the human body cool down. In the face of such catastrophic climate, the health and even lives of the economically disadvantaged population are extremely threatened.

[0003] In addition to the above situation, for some high-temperature working positions in open spaces, including outdoor operations in summer, traditional air conditioners are not suitable for use due to high energy consumption and inconvenience in carrying. Moreover, due to the complex structure of traditional air conditioners and the need for heat dissipation, it is difficult to make a portable structure.

[0004] The traditional water curtain machine cools by the evaporation of water in a wet paper honeycomb, but the specific surface area of the paper honeycomb is small, and the gaps in the paper wet curtain are large, with uneven water film distribution. The utilization rate of the effective evaporation area is less than 50%, and the refrigeration effect is poor. To achieve a certain required refrigeration capacity, a large volume of paper honeycomb is needed, so it is difficult to make a small-sized model.

[0005] Currently, there is a publicly known technology that uses a honeycomb body for evaporation refrigeration, but this technology requires a water pump, a spray head, and an electronic controller to spray water on the honeycomb body. As is well known, the water pump is a device with a relatively high failure rate, and the spray head often gets clogged. The electronic controller is difficult to repair for non-professionals. If the above devices are used in products, in addition to significantly increasing the manufacturing cost, it will also bring a considerable amount of after-sales service costs. These costs will ultimately be added to the commodity price, and the high commodity price is difficult to adapt to the consumption capacity of the economically disadvantaged population. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a cold air blower with a light and compact structure, good refrigeration effect, low operating energy consumption, high reliability, convenient use and maintenance, and low cost.

[0007] The present invention can adopt the following technical solutions:

[0008] A portable energy-saving air cooler: It includes a housing, a fan, a honeycomb body and a swing mechanism; inside the housing, there are an air inlet, an air passage and an air extraction area connected in sequence. A water storage area is provided below the air passage, and the fan is provided in the air extraction area to exhaust air externally. A swing mechanism is provided in the air passage; the swing mechanism includes a fulcrum, a fixed plate and a handle; the fixed plate is located inside the housing and is connected to the handle; the fulcrum is provided on the housing or a frame inside the housing, and the honeycomb body is installed on the fixed plate; by pulling the handle, the fixed plate can swing around the fulcrum, so that the whole honeycomb body is in the position inside the air passage or falls into the water storage area.

[0009] The problems solved by the present invention can further adopt the following improvement measures:

[0010] A further improvement measure is: a water injection port is provided at the top of the housing.

[0011] A further improvement measure is: the honeycomb body 3 is a zeolite-based honeycomb body or a carbon molecular sieve honeycomb body or a nano-ceramic honeycomb body.

[0012] A further improvement measure is: when the honeycomb body is in the position of the air passage, the direction of its honeycomb pores is consistent with the air passing direction.

[0013] A further improvement measure is: the housing is provided with a locking mechanism, and the locking mechanism can lock the handle to maintain the honeycomb body in the position of the air passage.

[0014] A further improvement measure is: a water level observation window is provided in the water storage area.

[0015] A further improvement measure is: a rotating shaft is provided at the corresponding position of the fulcrum, and the fixed plate and the handle are respectively fixed on the rotating shaft.

[0016] A further improvement measure is: the handle is provided outside the housing.

[0017] The above technical solutions have the following technical effects:

[0018] 1. The present invention can be made into a small and delicate air cooler, suitable for personal enjoyment, and is convenient to carry and can be used outdoors and during travel.

[0019] 2. There is only one fan in the electrical components of the present invention, without a water pump and a nozzle, reducing electrical failures and nozzle blockage problems, and its structure is simple and easy to maintain.

[0020] 3. The present invention has the characteristics of energy saving and low cost. It can obtain the effect of an air conditioner at the price and power consumption equivalent to that of an ordinary electric fan, has a very high cost performance, and is suitable for the consumption ability of low-income people. In places lacking grid power, a small solar battery or a car power supply can also meet the power supply needs.

[0021] 4. The honeycomb material used in the present invention has developed capillary channels and a large specific surface area, which greatly improves the evaporation rate of water. The refrigeration COP can reach more than 2.5, approaching the level of compression refrigeration, far exceeding the refrigeration efficiency of traditional water curtain air conditioners below 1.5.

[0022] 5. The honeycomb body used in the present invention has a very high evaporation refrigeration efficiency, and a relatively small honeycomb structure can obtain a large refrigeration capacity, meeting the basic conditions for making small-sized models.

[0023] 6. The refrigeration process of the present invention saves energy without the work of a compressor, eliminates the trouble caused by external heat discharge, and reduces environmental pollution without using chemical refrigerants.

[0024] 7. In addition to the air conditioning function, the wet honeycomb pores can adsorb dust to purify the air. Since the pore diameter of the honeycomb body's nano-scale base material is extremely small, several orders of magnitude smaller than the particle size of dust in the air, the micropores will not be blocked.

[0030] The present invention will be specifically described below in conjunction with specific embodiments.

[0031] Embodiment 1: As shown in FIG Figures 1 - 3As shown in the figure, a portable energy-saving air cooler includes a housing 1, a fan 2, a honeycomb body 3 and a swing mechanism; an air inlet 11, an air passage 12 and an air extraction area 13 are sequentially communicated inside the housing 1; a water storage area 8 is arranged below the air passage 12; the fan 2 is arranged in the air extraction area 13 to exhaust air externally; a swing mechanism is arranged in the air passage 12; the swing mechanism includes a fulcrum 6, a fixing plate 4 and a handle 5; the fixing plate 4 is located inside the housing, and the fixing plate 4 is connected to the handle 5; the fulcrum 6 is arranged on the housing or a frame inside the housing, and the honeycomb body 3 is installed on the fixing plate 4; by pulling the handle 5, the fixing plate 4 can swing around the fulcrum 6, so that the whole honeycomb body 3 is in the position inside the air passage 12 or falls into the water storage area 8.

[0032] In this example, the honeycomb body 3 is a zeolite-based honeycomb body. It can be that the honeycomb body is made of zeolite molecular sieve material, carbon molecular sieve material or nano-ceramics as the base material.

[0033] In this example, a water injection port 9 is arranged at the top of the housing 1.

[0034] In this example, the handle 51 is arranged outside the housing 1. The swing mechanism can pull the handle 5 through the handle 51 arranged outside the housing 1 to make the whole honeycomb body 3 installed on the fixing plate 4 in the position inside the air passage 12 or fall into the water storage area 8.

[0035] In this example, when the honeycomb body 3 is in the position of the air passage 12, the direction of its honeycomb pores is consistent with the air passing direction, showing a horizontal or nearly horizontal direction. When the honeycomb body 3 is in the position inside the water storage area 8, the direction of its honeycomb pores is vertical or nearly vertical.

[0036] In this example, the honeycomb body 3 is arranged in the horizontal air passage 12, and the air extraction area 13 is communicated with the air passage 12 in the horizontal direction, and other gaps except the air passage 12 are closed by a partition 7.

[0037] In this example, when the honeycomb body 3 is in the position of the air passage 12, the housing 1 is provided with a buckle to lock the handle 5 to prevent the honeycomb body 3 from falling due to gravity. The buckle has the function of a locking mechanism.

[0038] In this example, the water storage area 8 is provided with a water level observation window.

[0039] An improvement measure is that a rotating shaft is arranged at the corresponding position of the fulcrum 6, and the fixing plate 4 and the handle 5 are respectively fixed on the rotating shaft.

[0040] Working principle:

[0041] Embodiment 1 appendix Figures 1 - 3, the working process of this example: Before use, inject water into the water injection port 9 at the top of the housing. Stop injecting water when the water level reaches the upper limit line 10 of the observation window. Then, turn the handle 51 clockwise. When the handle 5 touches the limiting device, turn the handle counterclockwise back to the initial limiting point and fix the handle in place with a buckle. After completing the above operations, the honeycomb body 3 returns to the air passage 12 position after soaking and absorbing water. Then, start the fan to generate low-temperature cold air. When it is felt that the outlet air temperature rises, turn the handle again according to the previous method to let the honeycomb body absorb water again, and the refrigeration function can be restored. There is no need to turn off the fan during operation.

[0042] When the present invention operates continuously, according to different climatic conditions, the water absorption cycle of the honeycomb body is generally about 30 minutes. As long as the water can soak more than two-thirds of the height of the honeycomb body, the honeycomb body can basically be saturated with water through self-permeation of water. Each time the water storage area is filled with water, it can meet the water absorption requirements of the honeycomb body more than 5 times. Therefore, the frequency of turning the handle and injecting water is very low, and it will not make people feel troublesome.

[0043] The refrigeration principle of the present invention: Utilize the suction force of the fan 2. When the air flowing through the air passage 12 enters the honeycomb pores of the zeolite molecular sieve, the moisture on the pore wall is desorbed and forms water vapor, which is carried out by the wind. When the moisture evaporates, it will absorb heat. Since the honeycomb body has a large air passage area, and the molecular sieve material has an extremely high specific surface area, plus the open microporous structure of the molecular sieve material, the dense capillary tubes formed from the inside to the outside will accelerate the outward penetration of the internal moisture. After these several factors are superimposed, the gasification efficiency of the moisture in the molecular sieve is greatly improved. The latent heat required for the gasification phase change of the moisture is obtained by absorbing the sensible heat in the honeycomb body. When the water vapor leaves the honeycomb pore wall, it has transferred the cold to the honeycomb body to cool it. The subsequent flowing air is cooled by the cooled honeycomb body to generate cold air.

[0044] Due to the structure and performance of the molecular sieve material far exceeding that of the honeycomb paper material, compared with the water curtain air conditioner, the present invention can evaporate more moisture in the same flow rate of air and obtain more gasification latent heat heat exchange. This is the main factor that the refrigeration efficiency and outlet air temperature of the present invention are far superior to those of the water curtain air conditioner. Therefore, under the same refrigeration capacity, the volume of the present invention is smaller.

[0045] This example also has an extremely high dust removal function. The wet honeycomb pores can adhere to extremely small particulate matters in the air, solving the problem that the filtering effect becomes poor when the filter mesh holes of the traditional air conditioner are too large and the problem that it is easy to cause blockage when the filter mesh holes are too small.

[0046] In this example, the honeycomb body is soaked manually to keep it moist, without the need to increase the costs of water pumps, nozzles and electronic controllers, and also reducing the after-sales service costs caused by the failures of the above-mentioned devices. There is only one fan among the electrical components, and the probability of the fan failing is very low. In this way, the manufacturing cost of the small cooling fan designed with the structure of this example can be reduced to dozens of yuan, and its selling price can even be lower than that of ordinary household electric fans, making it affordable for low-income people and most people with financial difficulties.

[0047] Embodiment 2: As shown in the attached Figures 4 - 5 figure, a portable energy-saving cooling fan includes a housing 1, a fan 2, a honeycomb body 3 and a swinging mechanism; an air inlet 11, an air passage 12 and an air extraction area 13 are sequentially communicated inside the housing 1. A water storage area 8 is arranged below the air passage 12, and the fan 2 is arranged in the air extraction area 13 to exhaust air externally. A swinging mechanism is arranged in the air passage 12; the swinging mechanism includes a fulcrum 6, a fixing plate 4 and a handle 5; the fixing plate 4 is located inside the housing, and the fixing plate 4 is connected to the handle 5; the fulcrum 6 is arranged on the housing or a frame inside the housing, and the honeycomb body 3 is installed on the fixing plate 4; by pulling the handle 5, the fixing plate 4 can swing around the fulcrum 6, so that the whole honeycomb body 3 is in the position inside the air passage 12 or falls into the water storage area 8.

[0048] The main difference between this Example 2 and Embodiment 1 is that: Example 2 has a vertical structure, and the air outlet and the air inlet are on the same side.

[0049] In this example, the honeycomb body 3 is made of nano-porous ceramics as the base material.

[0050] In this example, a water injection port 9 is arranged at the top of the housing 1, and a water pipe is led from the water injection port into the water storage area 8.

[0051] In this example, the swinging mechanism can be used to pull the handle 5 through a handle 51 arranged outside the housing 1 to make the whole honeycomb body 3 installed on the fixing plate 4 be in the position inside the air passage 12 or fall into the water storage area 8.

[0052] In this example, when the honeycomb body 3 is in the position of the air passage 12, the direction of its honeycomb pores is the same as the air passing direction, showing a horizontal or nearly horizontal direction. When the honeycomb body 3 is in the position inside the water storage area 8, the direction of its honeycomb pores is vertical or nearly vertical.

[0053] In this example, the honeycomb body 3 is arranged in a horizontal air passage 12. The air extraction area 13 is communicated with the air passage 12 in the up and down direction, and other gaps except the air passage 12 are closed by a partition 7.

[0054] In this example, when the honeycomb body 3 is in the air passing channel position 12, the housing 1 is provided with an elastic mechanism to fix the handle 5 to prevent the honeycomb body 3 from falling due to gravity.

[0055] In this example, the water storage area 8 is provided with a water level observation window.

[0056] The main difference between Example 2 and Example 1 is that Example 2 is a vertical structure, and the air outlet and the air inlet are on the same surface. The advantage is that the thickness of the housing can be further reduced, reducing the area occupied, and it will not block the air inlet when placed against the wall.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
