Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fans, and particularly to a refrigeration structure of a cold air fan and a cold air fan.
Background Art
[0002] An air-conditioning fan refers to a fan that has the function of adjusting the air in the natural environment, such as heating the air in the natural environment to warm air and blowing it out, or cooling the air in the natural environment to cold air and blowing it out, and changing the attribute of the wind according to actual needs.
[0003] Currently, many air-conditioning fans on the market use a compressor or a thermoelectric semiconductor to perform refrigeration or heating treatment on the air. However, when applying such equipment, due to the existence of the principle of equivalent energy exchange, when refrigerating the air, heat is generated simultaneously, and when heating the air, cold is generated simultaneously, which is a very contradictory phenomenon. For example, when using a fan to refrigerate in a hot environment, the generated heat needs to be discharged by installing a corresponding exhaust heat system so as not to cause the phenomenon that the heat accumulates in the fan body and becomes high temperature. The actual demand of consumers for the fan is to require the fan to blow cold air to cool. In this way, exhausting heat while blowing cold air will affect the user experience of consumers. When using such an air-conditioning fan in a closed small space, such as inside a car, the heat cannot be discharged to the outside, which will cause cold and heat circulation in the small space, not only unable to achieve an ideal use effect, but also deteriorate the environment and cause energy loss.
[0004] To overcome the above technical problems, Chinese Patent Document with Publication No. CN218820752U discloses an air-conditioning fan including a blowing assembly and an air-conditioning device. The air-conditioning device includes a conduction member including a housing cavity for accommodating a heating or cooling substance. A part of the outer wall of the housing cavity protrudes and extends on the surface to form diffusion wings, and a ventilation duct is formed between the diffusion wings. An air intake hole is installed in the housing of the air-conditioning device. The blowing assembly guides the air located at the air intake hole, passes it through the ventilation duct, and then blows it outwards. When it is necessary to produce cold air, rotate the blowing assembly to release the snap connection with the upper port member of the air-conditioning device, then take out the blowing assembly from the air-conditioning device, withdraw the cavity plug from the mouth of the housing cavity, then put ice water or ice into the cavity, and then cover the blowing assembly again so that the cavity plug seals the mouth of the housing cavity. When the refrigerating substance releases the cooling capacity in the housing cavity, the cooling capacity is conducted to the diffusion wings, and the ventilation duct around the diffusion wings forms a refrigeration area. By operating the blowing assembly through the control panel, the fan assembly drives the air located at the air intake hole on the bottom case to pass through the ventilation duct, then enter the ventilation hole, and finally blow out from the ventilation hole. When the air enters the ventilation duct, it is cooled by the ventilation duct and the diffusion wings in the refrigeration area, thereby converting the natural wind into cold air and blowing it outwards.
[0005] In the technical solution disclosed in the above patent document, when the air flow is cooled through the diffusion wings, the moisture in the air flow condenses on the diffusion wings. When a large amount of water droplets accumulate on the diffusion wings, they drip inside the fan or on the table, and the aggregated water may also enter the motor along the air flow.

In the mount, a stopper for attaching and stopping the cooling package is installed. At the bottom end of the mount, a water groove for receiving water droplets formed by condensation of the cooling package is installed.
[0008] Furthermore, the mount is a housing surrounded by a hollow structure.
[0009] Furthermore, on one side of the mount, a cavity for forming the mount into an outer ring side wall and an inner ring side wall is further installed, and the water groove is installed on one side of the bottom end of the outer ring side wall.
[0010] Furthermore, the stopper includes elastic arms installed opposite to both sides of the outer ring side wall.

Modes for Carrying Out the Invention
[0021] In an embodiment of the cold air fan of the present utility model, referring to FIGS. 1 to 3, the cold air fan of this embodiment can realize that the blown airflow is cold air. Specifically, it includes a refrigeration structure, a barrel 100, a motor 200, a fan blade 300, a front mesh 400, and a rear mesh 500.
[0022] Referring to FIG. 3, inside the barrel 100, a duct 101 having an air intake end 102 and an air outlet 103 is installed, the fan blade 300 is installed inside the barrel 100, and the motor 200 is connected to the fan blade 300. The front mesh 400 caps the air outlet 103, and the rear mesh 500 caps the air intake of the barrel 100.
[0023] Referring to FIGS. 3 to 5, the refrigeration structure of the cold air fan includes a cooling package 600 and a mount 700. Inside the cooling package 600, a storage cavity 605 for storing a coolant is installed. In the cooling package 600, a plurality of air flow through holes 601 for the airflow to pass through and exchange heat with the coolant in the storage cavity are further installed. Specifically, the coolant may be ice water, refrigerant, etc., or may be ice. Specifically, water is filled into the storage cavity, and the cooling package 600 is placed in a refrigerator and frozen to obtain ice. On the mount 700, a stopper 710 for mounting and stopping the cooling package 600 is installed. At the bottom end of the mount 700, a water groove 720 for receiving water droplets formed by the condensation of the cooling package 600 is installed.
[0024] The cold air fan of the above embodiment can add a coolant or other refrigerant into the accommodation cavity of the cooling package. The cooling package 600 is attached to the mount 700. In the case of the cooling air, the air flow passes through the air flow through hole 601 and exchanges heat with the coolant or ice in the cooling package 600, and the air flow output from the air flow through hole 601 is endothermic and the temperature drops. The moisture in the air flow or the moisture in the air aggregates on the cooling package 600. When there is relatively a lot of aggregated water, it drips into the water groove 720 along the side wall of the cooling package 600, collects the water flow, avoids the aggregated water flowing to other positions, plays a good protective role for the fan, and can also dry the environment.
[0025] Furthermore, referring to FIGS. 2 and 3, inside the rear mesh 500, mounting positions 501 installed in a plurality of locking grooves 502 are provided. On the side opposite to the stopper 710 of the mount 700, a plurality of elastic buckles 701 for engaging with the locking grooves 502 are installed. One end of the stopper 710 also extends a hand position 712. In this embodiment, the mount 700 attaches the cooling package 600 to the rear mesh 500, attaches the cooling package 600 to the rear mesh 500, the structure is simple, and the operation is easy. In addition, the hand position 712 makes it easier to attach and detach the mount 700.
[0026] Furthermore, the mount 700 is a housing surrounded by a hollow structure. Therefore, when the cooling package 600 is attached to one side of the mount 700, the air flow enters the air flow through hole 601 of the cooling package 600 from the hollow part of the housing. Preferably, the mount 700 has an annular or semi-annular structure.
[0027] Furthermore, referring to FIGS. 4 to 7, on one side of the mount 700, a cavity 702 for forming the mount 700 into an outer ring side wall 703 and an inner ring side wall 704 is further provided, and the water groove 720 is installed on one side of the bottom end of the outer ring side wall 703. In this embodiment, in the actual movement process of the cold air fan, the head may swing up and down, so the water in the water groove 720 can enter the cavity 702, effectively avoiding the overflow of the water flow from the water groove 720.
[0028] Furthermore, referring to FIGS. 6 and 7, the stopper 710 includes elastic arms 711 installed opposite to both sides of the outer ring sidewall. The two elastic arms 711 and the water groove 720 form a fixed position for accommodating the cooling package 600 to support and stop the cooling package 600. At the free end of the elastic arm 711, a stopper portion 713 extending inside the fixed position is installed. In this embodiment, the bottom of the cooling package 600 is supported by the water groove 720, the cooling package 600 is clamped by the two elastic arms 711, and the stopper portion 713 of the elastic arm 711 stops the cooling package 600, so that the cooling package 600 can be stably supported and the cooling package 600 can be brought into contact with the air flow with the maximum area. In addition, a three-point supported cooling package 600 is adopted, with a simple structure and easy attachment and detachment.
[0029] Furthermore, referring to FIGS. 6 and 7, the water groove 720 includes a bottom plate 721 extending from one side of the bottom end of the outer ring sidewall 703 and having a side plate 722 formed and extending at one end away from the mount 700.
[0030] Furthermore, the bottom plate 721 is an arc plate with both ends curved upward and extending. When the cooling package 600 is supported by the water groove 720, both ends of the cooling package 600 are supported by both ends of the bottom plate 721, and the inside of the side plate 722 stops the cooling package 600, so that the cooling package 600 is suspended above the water groove 720, and the water groove 720 can receive more water.
[0031] Furthermore, in order to reduce the contact area between the side plate 722 and the cooling package 600 and allow the water aggregated on the cooling package 600 to flow well into the water groove 720, bumps 723 are further installed inside the side plate 722. Specifically, referring to FIG. 7, the side wall of the cooling package 600 is supported by the bumps 723. A gap is formed between the cooling package 600 and the inside of the side plate 722, and the water flow can flow downward through the gap, avoiding the problem that the water flow outside the cooling package 600 drips downward along the side plate 722.
[0032] Furthermore, referring to FIG. 8, one side surface that is bonded to the mount 700 of the cooling package 600 is recessed inward to form an inner spherical surface 602, and the other side surface of the cooling package 600 arches outward to form an outer spherical surface 603. When the cold air fan swings its head up and down, the water flow that has aggregated on the surface of the cooling package 600 can flow downward along the spherical surface under the action of gravity, facilitating the collection and recovery of water. Also, since the inner spherical surface is formed inside the cooling package 600, a certain arch gap is formed on-site between the inside of the cooling package 600 and the mount 700, making it easier for the accumulated water to be discharged into the water channel 720.
[0033] Furthermore, referring to FIG. 8, water stop rings 604 are installed at both ports of the air flow through hole 601. The water stop rings 604 can form a waterproof dam, effectively preventing the problem that water enters the air flow through hole 601 and is sucked into the fan blade along the air flow.
[0034] The above are only preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle scope of the present utility model shall all be included within the protection scope of the present utility model.
