TECHNICAL FIELD

[0001] The present application relates to the technical field of air coolers, in particular to a portable air cooler. BACKGROUND

[0002] In the prior art, there are indoor air coolers and outdoor air coolers, which are devices for adjusting or controlling the temperature, humidity, flow rate and other parameters of the local environment by artificial means. The air cooler provides a cool environment for the user, which can effectively improve the comfort of the user, and therefore is favored by the majority of consumers.

[0003] The indoor air cooler is large in size and usually needs to be fixedly installed for use inside a building. It is difficult for the user to carry this type of air cooler to an outdoor scene for use.

[0004] The outdoor air cooler is smaller in size than the indoor air cooler and is a device in which a compressor, an evaporator and a condenser are integrated together. The entire air cooler is compact in structure. In the outdoor air cooler, the condenser, the compressor and the evaporator are respectively separated by a sealing baffle to form multiple working areas, so as to realize the exchange of cold air and hot air inside the air cooler.

[0005] The inventor finds that whether the indoor air cooler or the outdoor air cooler on the market is used, the internal structure of the two types of air coolers is very complex. Although the outdoor air cooler improves the space utilization rate of the internal cavity of the air cooler by adjusting the positions of various mechanisms inside, it achieves the purpose of reducing the size to a certain extent. However, since the number of mechanisms inside is not reduced, the overall weight of the air cooler is still very heavy, which makes it difficult for the user to carry. SUMMARY

[0006] In order to simplify the structure of the air cooler, the present application provides a portable air cooler, which can reduce the burden of the user when carrying the air cooler.

[0007] The portable air cooler provided by the present application adopts the following technical scheme:

[0013] The air suction mechanism sucks the external hot air into the shell, the refrigerating device cools the hot air, and the air outlet mechanism is used for discharging the cold air.

[0014] By adopting the above technical scheme, under the action of the air suction mechanism, the external hot air can be sucked into the shell, and under the action of the refrigerating device, the hot air can be cooled, and the air suction mechanism then discharges the cold air cooled by the refrigerating device from the output end of the air outlet mechanism. Compared with the prior art, first, the shell has a through inner cavity, so that the air inlet and outlet process of the cold air device is good in continuity, and the hot air and the cold air are subjected to very small resistance, so that the user can be provided with a continuous cold source, and the user experience is improved. Second, the cold air device of the application eliminates the complex mechanism of the compressor, the evaporator and the condenser, simplifies the structure of the cold air device, and can reduce the weight of the cold air device, thereby reducing the burden of the user when carrying the cold air device.

[0015] Preferably, the shell has a drainage portion.

[0016] By adopting the above technical scheme, after the hot air enters the shell, the hot air contacts the refrigerating device to generate water droplets. Since the shell has a drainage portion, the water droplets in the shell can be smoothly discharged, which helps to reduce damage to the air suction mechanism caused by accumulated water and to protect the service life of the air suction mechanism.

[0017] Preferably, the bottom end of the refrigerating device and the side wall of the air suction mechanism leave a wind collection interval.

[0019] Preferably, the refrigerating device has a structure reinforcing portion.

[0020] By adopting the above technical scheme, the refrigerant in the refrigerating device expands and contracts with heat, and the liquid storage dish of the refrigerating device requires a certain expansion space. Since the refrigerating device has a structure reinforcing portion, the overall structural strength of the refrigerating device can be enhanced, the liquid storage dish of the refrigerating device can be prevented from deforming and cracking, and the service life of the refrigerating device can be prolonged.

[0021] Preferably, the refrigerating device has a water guide portion, and the adjacent two water guide portions are in point contact, and the water guide portion is used for guiding the water droplets attached to the outer wall of the refrigerating device.

[0022] By adopting the technical scheme, the two refrigerators can be leaned against each other without being prone to falling, water drops adhering to the water guide part can be guided under the action of the water guide part, and the water drop drainage efficiency can be improved.

[0023] Preferably, the shell comprises an air inlet part and an air outlet part, and the radial dimension of the air inlet part is narrower than the radial dimension of the air outlet part.

[0024] By adopting the technical scheme, the shell comprises an air inlet part and an air outlet part, and the radial dimension of the air inlet part is narrower than the radial dimension of the air outlet part.

[0025] Preferably, the air outlet mechanism comprises a stretchable pipe, which is detachably installed on the air outlet part of the shell and can realize self-stretching or change the air outlet angle.

[0026] By adopting the technical scheme, the user can adjust the length of the stretchable pipe and change the air outlet angle of the stretchable pipe, so as to adapt to users in different directions of the air cooler and improve the user experience.

[0027] Preferably, the air suction mechanism comprises an air suction part and a filter part, the filter part is arranged at the input end of the air suction part, and the filter part is used for filtering dust in external hot air.

[0028] By adopting the technical scheme, the filter part has good dust filtering function, and can filter dust or impurities in external hot air during the air suction process of the air suction mechanism, so as to reduce the damage of dust to the air suction mechanism and prolong the service life of the air suction mechanism. At the same time, the filtered cold air is cleaner, which can improve the user experience to a certain extent.

[0029] Preferably, the air suction mechanism is arranged at the air inlet part, the air outlet mechanism is arranged at the air outlet part, and a pressure difference is formed between the air inlet part and the air outlet part.

[0030] By adopting the technical scheme, a pressure difference is formed between the air inlet part and the air outlet part, which can accelerate the heat exchange speed between the air cooler and external air, so that the cold air cooled by the refrigerator can be quickly discharged from the air outlet mechanism, thereby rapidly cooling the environment around the air cooler.

[0031] Preferably, the shell can be detachably divided into multiple shell bodies, and the refrigerator can be disassembled after the multiple shell bodies are disassembled.

[0032] By adopting the technical scheme, the shell is divided into multiple shell bodies, so that the user can easily take the cooling device or conveniently maintain each mechanism placed inside the shell, which helps to improve the user's efficiency in checking the damage point of the cooling device and further helps to save the maintenance cost.

[0055] The following will be described in detail in combination with the accompanying Figures 1-10 The present application will be further described in detail.

[0056] The embodiment of the present application discloses a portable air cooler.

The shell 2 has a through inner cavity. The air suction mechanism 4 is installed at the middle of the bottom end of the shell 2. The cooler 3 is arranged at the top of the air suction mechanism 4. The air outlet mechanism 5 is detachably installed at the top end of the shell 2. The shell 2 is installed on the base 1, so that the shell 2 can be stably placed. In the present application, under the action of the air suction mechanism 4, external hot air can be sucked into the shell 2. The cooler 3 cools the hot air. The cold air is discharged through the output end of the air outlet mechanism 5. The air cooler continuously exchanges the external hot air and the internal cold air, so as to adjust the temperature of the local environment, thereby providing a cool environment for the user.

[0058] In the present application, the cooler 3 is at least two. In the present application, the air cooler comprises two coolers 3.

The air suction mechanism 4 is arranged below the two coolers 3. The output end of the air suction mechanism 4 is aligned with the wind channel 31.

[0059] The air suction mechanism 4 continuously sucks the external hot air and blows the internal cold air, so that the surrounding area of the output end of the air suction mechanism 4 is a high-pressure area. The wind channel 31 near the air outlet mechanism 5 forms a low-pressure area. During the air suction and exhaust process of the air suction mechanism 4, the air flows spirally. After the hot air is sucked into the air suction mechanism 4, the cold air cooled by the cooler 3 flows from the high-pressure area to the low-pressure area, so that the cold air is quickly discharged from the air outlet mechanism 5, and the speed of heat exchange between the air cooler and the external air is further accelerated.

In addition, when the cold air generator fails, the user can separate the air inlet part and the air outlet part to check the damage point, which helps to improve the user's efficiency of repairing the cold air generator.

The flow guide arc surface 32 is inclined downward from the top end of the liquid storage dish 36 to the water pan 6. The bottom end of the refrigeration device 3 is provided with flow guide inclined surfaces 33 on the outer sides. The flow guide inclined surfaces 33 are arranged to be inclined downward from the bottom end of the flow guide arc surface 32 to the reinforcing ribs 412 of the cover body 414, so that the flow guide inclined surfaces 33 of the refrigeration device 3 are pressed against the reinforcing ribs 412, and the flow guide inclined surfaces 33 and the air guide arc surface 411 form a wind collection interval.

[0085] The specific shape of the reinforcing ribs 412 and the size of the wind collection interval are not limited in the present application, and only the space for air exhaust and water drainage is required. In the embodiment of the present application, the reinforcing ribs 412 are selected to be triangular ribs, so that the wind collection interval between the flow guide inclined surfaces 33 and the air guide arc surface 411 is a wind collection channel 72. The flow guide inclined surfaces 33 of the refrigeration device 3 are pressed against the reinforcing ribs 412, so that a water falling channel 71 is left between the water pan 6 and the liquid storage dish 36, that is, a height space is left between the bottom surface of the liquid storage dish 36 and the water receiving groove 622 of the water pan 6.

[0086] At the same time, one side of the liquid storage dish 36 is in abutment with the long side wall of the power supply shell 81, and the liquid storage dish 36 is provided with water guide portions away from the power supply shell 81. The two water guide portions are in point contact. Through the action of the water guide portions, water droplets attached to the outer wall of the refrigeration device 3 can be guided.

[0087] Specifically, the water guide part is a water guide slope 34 formed on the side of the liquid storage dish 36 away from the power supply shell 81, the water guide slope 34 is arranged downwardly from the top end to the bottom end of the liquid storage dish 36, the two refrigerators 3 are abutted on the side with the water guide slope 34, and a water guide channel 73 is left between the two water guide slopes 34. By point contact between the adjacent two water guide parts, and under the cooperation of the power supply shell 81, the two refrigerators can be leaned against each other and are not easy to fall. Under the action of the water guide part, the water droplets adhering to the water guide part can be guided to quickly drain into the water pan.

[0088] With reference to Figure 6 and Figure 7 , the refrigerator 3 has a structure reinforcing part, which includes vertical reinforcing grooves 351 formed on the connecting arc surface 38 and horizontal reinforcing grooves 352 formed on the flow guide arc surface 32, the number of the vertical reinforcing grooves 351 and the horizontal reinforcing grooves 352 is determined according to the situation, so that a plurality of vertical reinforcing grooves 351 are uniformly arranged on the connecting arc surface 38 and a plurality of horizontal reinforcing grooves 352 are uniformly arranged on the flow guide arc surface 32. When the refrigerant expands and contracts in the liquid storage dish 36, the arrangement of the vertical reinforcing grooves 351 and the horizontal reinforcing grooves 352 can improve the structural stability of the liquid storage dish 36, thereby reducing the possibility of cracking of the liquid storage dish 36.

[0089] Furthermore, by arranging the horizontal reinforcing grooves 352 on the flow guide arc surface 32, the water flow of the water droplets adhering to the surface of the liquid storage dish 36 can be slowed down to some extent, so that the falling speed of the water droplets in the water falling hole 623 of the water pan 6 and the sliding speed of the water droplets on the surface of the flow guide arc surface 32 reach a balanced state.

[0090] The user starts the driving motor to rotate the air suction fan blade 42, so that the hot air outside the air cooler enters the air conveying channel 31 between the two refrigerators 3 from the air inlet 14. Since there is no active energy air flow to stir the air at the air converging channel 72, the pressure inside the air converging channel 72 is lower than that at the output end of the air suction mechanism 4, so the water droplets flow from the high-pressure area to the low-pressure area, that is, the water droplets can be quickly drained from the bottom end of the water guide slope 34 or from the air converging channel 72, and then fall into the liquid storage cavity 11 of the base 1, thereby improving the flow speed of the water droplets.

[0091] At the same time, the hot air inside the air cooler is cooled by the refrigerator 3 to obtain cold air, which is blown away under the agitation of the air suction fan blade 42. The end of the air conveying channel 31 close to the air outlet mechanism 5 has low temperature and small air volume, so the pressure at the end of the air conveying channel 31 close to the air outlet mechanism 5 is lower than that at the output end of the air suction mechanism 4, that is, a pressure difference is formed between the input end and the output section of the air conveying channel 31, so that the cold air is quickly discharged from the air outlet mechanism 5, thereby improving the flow speed of the cold air.

[0092] With reference to Figure 10, the shell 2 further comprises a first shell 21, and a connecting assembly is arranged between the first shell 21 and the second shell 22, and the first shell 21 is detachably mounted with the second shell 22 through the connecting assembly. Specifically, the connecting assembly comprises a fixed plug 231 and a clamping column 233, the diameter size of the fixed plug 231 is smaller than the outer diameter size of the second shell 22, the fixed plug 231 is fixed at the top end of the second shell 22, so that the assembly step 24 is formed between the fixed plug 231 and the second shell 22, the connecting rubber ring 25 is sleeved in the assembly step 24, the light strip is arranged in the connecting rubber ring 25, the light strip is electrically connected with the power control panel, the top end of the fixed plug 231 is provided with a clamping groove 232, the clamping groove 232 is an L-shaped groove, and the two clamping grooves 232 have long edges arranged on the same circumferential line in clockwise direction, that is, the two clamping grooves 232 are consistent in direction, and correspondingly, the two clamping columns 233 are fixed on the inner wall of the first shell 21.

[0093] By sleeving the connecting rubber ring 25 in the assembly step 24, then fitting the first shell 21 with the fixed plug 231, rotating the first shell 21, and clamping the two clamping columns 233 with the two clamping grooves 232, the connection between the first shell 21 and the second shell 22 is completed, and at the same time, the connecting rubber ring 25 is tightly compressed in the assembly step 24 by the first shell 21, which helps to improve the connection density between the first shell 21 and the second shell 22. The light strip will become bright after being powered on, so as to facilitate the user to use the air cooler at night, and to improve the overall appearance of the air cooler to a certain extent.

[0094] In the embodiment of the present application, the first shell 21 comprises an air outlet end 211 and an air inlet end 212, the end of the first shell 21 close to the second shell 22 is the air inlet end 212, the diameter size of the air inlet end 212 of the first shell 21 is consistent with the diameter size of the second shell 22, and the end of the first shell 21 close to the air outlet mechanism 5 is the air outlet end 211, the diameter of the air inlet end 212 of the first shell 21 is greater than the diameter of the air outlet end 211, and by gradually narrowing the first shell 21, the air outlet effect of the air outlet mechanism 5 is improved.

[0095] Referring to Figure 2 and Figure 10 , the air outlet mechanism 5 comprises a stretching pipe 51 and a pipe head 52, the stretching pipe 51 is distributed between the air outlet end 211 and the pipe head 52, and a pipe joint assembly is arranged between the air outlet end 211 and the stretching pipe 51 and between the pipe head 52 and the stretching pipe 51, respectively, the stretching pipe 51 is detachably mounted with the air outlet end 211 through one pipe joint assembly, and the pipe head 52 is detachably mounted with the stretching pipe 51 through another pipe joint assembly.

[0096] Specifically, the stretchable pipe 51 is a shapeable screw pipe, the pipe joint assembly comprises a first screw ridge group 531 and a second screw ridge group 532, the first screw ridge group 531 is fixed to the inner wall of the air outlet end 211, the second screw ridge group 532 is fixed to the inner wall of the pipe head 52, one end of the stretchable pipe 51 is threadedly connected with the first screw ridge group 531, and the pipe head 52 is threadedly connected with the stretchable pipe 51 through the second screw ridge group 532. A user can adjust the length of the stretchable pipe 51 by pulling the stretchable pipe 51, and the position of the air outlet of the pipe head 52 can be changed accordingly, so that the position of the user can be adapted.

The pressure at the output end of the air suction mechanism 4 is greater than the pressure at the air outlet end 211 of the first shell 21, so that the cold air can be quickly discharged from the air outlet mechanism, thereby improving the user experience.

[0098] The implementation principle of the portable cold air machine in the embodiment of the present application is as follows:

[0099] The user rotates the first shell 21 to make the clamping columns 233 disengage from the clamping grooves 232 of the fixed plugs 231, thereby separating the first shell 21 from the second shell 22. The user installs the two refrigerators 3 cooled after cooling in the second shell 22, and then aligns the first shell 21 to be plugged on the fixed plugs 231. The user rotates the first shell 21 to make the two clamping columns 233 correspondingly clamp the two clamping grooves 232, thereby completing the connection between the first shell 21 and the second shell 22.

[0100] The driving motor is started, and the air suction fan blade 42 can rotate. The external hot air enters the air conveying channel 31 between the two refrigerators 3 from the air inlet 14. The refrigerator 3 exchanges heat with the hot air remaining in the air conveying channel 31. The air suction fan blade 42 blows the cold air out of the pipe head 52. The user can adjust the length of the stretchable pipe 51, thereby changing the position of the air outlet of the pipe head 52 to adapt to the position of the user.

[0101] After the hot air in the cold air machine contacts the refrigerator 3, the liquidization phenomenon occurs.
