Description

Technical Field

[0001] This utility model relates to the technical field of fans, and particularly to a cold air type 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, heat is generated simultaneously when refrigerating the air, and cold heat is generated simultaneously when heating the air, which is a very contradictory phenomenon. For example, when using a fan for refrigeration 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 of heat accumulation in the fan body and high temperature development of the developing machine. The actual demand of consumers for the fan is to require the fan to blow cold air for cooling. 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, so it will cause cold 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 No. CN218820752U discloses an air-conditioning fan including a blower assembly and an air-conditioning device. The air-conditioning device includes a conductive member including a receiving cavity for accommodating a heating or cooling substance. A part of the outer wall of the receiving 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 blower 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 blower assembly to release the snap connection with the upper port member of the air-conditioning device, then remove the blower assembly from the air-conditioning device, withdraw the cavity plug from the mouth of the receiving cavity, then put ice water or ice into the cavity, and then cover the blower assembly again so that the cavity plug seals the mouth of the receiving cavity. When the refrigerating substance releases a cooling capacity in the receiving cavity, the cooling capacity is conducted to the diffusion wings, and the ventilation duct around the diffusion wings forms a refrigerating area. By operating the blower 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, enter the ventilation hole, and finally blow outwards from the ventilation hole. When the air enters the ventilation duct, it is cooled down by the ventilation duct and diffusion wings in the refrigerating area, thereby converting the natural wind into cold air and blowing it outwards.

[0005] The technical solution disclosed in the above patent document requires first removing the upper case, further putting ice water or ice into the cavity, then covering the blower assembly again so that the cavity plug seals the mouth of the receiving cavity, and capping the upper case. Due to the high frequency of ice replacement, there are inconvenient problems in the operations of ice replacement and addition.

Modes for Carrying Out the Invention

[0022] In an embodiment of the cold fan of the present utility model, referring to FIGS. 1 to 3, the cold air fan of this embodiment can realize that the blown air flow is cold air. Specifically, it includes a barrel 100, a motor 200, a fan blade 300, a front mesh 400, a rear mesh 500 and a refrigeration package 600.

[0023] Referring to FIGS. 2 and 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. An attachment position 501 is installed on the rear mesh 500, and the refrigeration package 600 is removably installed at the attachment position 501. A plurality of through holes 601 for the air flow to pass through are installed in the refrigeration package 600. In the fan of this embodiment, when the motor 200 rotates the fan blade 300, an air flow is formed in the duct 101. The air flow entering the duct 101 is absorbed by heat by the refrigeration package 600 and its temperature is reduced. Therefore, the air flow blown out from the air outlet 103 is cold air, and it has a high heat dissipation and temperature reduction effect on the human body and the like. Since the refrigeration package 600 is removably installed on the rear mesh 500, the refrigeration package 600 can be directly removed, or the refrigeration package 600 can be removed after removing the rear mesh 500 to replace the refrigeration package 600, so the operation is simple and convenient.

[0024] Furthermore, it is an embodiment in which the refrigeration package 600 is removably attached to the rear mesh 500. Specifically, referring to FIG. 2, on the end face of the rear mesh 500, a mounting cavity 510 recessed inward is installed. A plurality of ventilation holes 511 are installed on the bottom wall of the mounting cavity 510, and the refrigeration package 600 is installed in the mounting cavity 510. The refrigeration package 600 can be directly attached into the mounting cavity 510, and when removing it, it only needs to be taken out from the mounting cavity 510.

[0025] Furthermore, there is another embodiment in which the refrigeration package 600 is removably attached to the rear mesh 500. Specifically, referring to FIG. 3, the rear mesh 500 is removably connected to the body 100, and the refrigeration package 600 is installed inside the rear mesh 500. Specifically, when removing and replacing the refrigeration package 600, after removing the rear mesh 500 from the end of the body 100, the refrigeration package 600 may be removed and replaced from inside the rear mesh 500. By installing the refrigeration package 600 inside the rear mesh 500, it can play a role in protecting the refrigeration package 600.

[0026] Furthermore, there is an embodiment in which the rear mesh 500 is removably connected to the body 100. Specifically, a plurality of protruding blocks 110 with stopper grooves 111 installed are extended at the end of the body 100, and a stopper rib 502 for engaging with the stopper groove 511 is further installed on the inner wall of the end of the rear mesh 500. Specifically, when attaching the rear mesh 500 to the end of the body 100, covering the rear mesh 500 on the end of the body 100 and rotating the rear mesh 500, the stopper rib 502 of the rear mesh 500 is engaged into the stopper groove 511 to engage with each other. When removing, rotating the rear mesh 500 in the reverse direction and the stopper rib 502 detaching from the stopper groove 511, the rear mesh 500 can be removed.

[0027] Furthermore, the cold air fan further includes a mount 700 connected to the rear mesh 500, and the refrigeration package 600 is removably installed on the mount 700. In this embodiment, by adopting the mount 700 to support and fix the refrigeration package 600, the attachment and detachment of the refrigeration package 600 can be made easier.

[0028] Furthermore, referring to FIGS. 3 to 7, the mount 700 includes a housing 710 surrounded by a hollow structure. Preferably, the housing 710 may be annular or may have a semi-circular structure. On one side of the housing 710, a mounting groove 720 for attaching the refrigeration package 600 is provided, and at the bottom of the mounting groove 720, a water receiving groove 730 for receiving water droplets condensed by the refrigeration package 600 is provided. Specifically, the refrigeration package 600 can be attached within the mounting groove 720, and the mounting groove 720 fixes the refrigeration package 600. When removing the refrigeration package 600, it is only necessary to pull the refrigeration package 600 out of the mounting groove 720. Also, water droplets formed by the condensation of moisture in the air coming into contact with the refrigeration package 600 can be stored in the water receiving groove 730, and after removing the refrigeration package 600, the water in the water receiving groove 730 can be drained and the groove can be cleaned.

[0029] Furthermore, referring to FIG. 8, one side surface of the refrigeration package 600 that is bonded to the mount 700 is recessed inward to form an inner spherical surface 602, and the other side surface of the refrigeration package 600 arches outward to form an outer spherical surface 603. When the fan swings its head up and down, the water flow aggregated on the surface of the refrigeration package 600 can flow downward along the spherical surface under the action of gravity, facilitating the collection and recovery of water. Also, the formation of the inner spherical surface 602 inside the refrigeration package 600 creates a certain arch gap on-site between the inside of the refrigeration package 600 and the mount 700, making it easier for the accumulated water to be discharged into the water receiving groove 730.

[0030] Furthermore, referring to FIG. 8, water stop rings 604 are installed at both ports of the through hole 601. The water stop rings 604 can form a waterproof dam, effectively preventing the problem of water entering the through hole 601 and being sucked into the fan blades along the air flow.

[0031] Furthermore, referring to FIG. 6, one side of the mounting groove 720 of the housing 710 that is close to the inner side is recessed inward to form a concave groove 711. The concave groove 711 forms the housing 710 into an inner ring side wall 712 and an outer ring side wall 713, and a water receiving groove 730 is installed at the bottom end of the outer ring side wall 713. In this embodiment, during the actual movement process of the fan, the head may swing up and down. Therefore, during the swinging process, the flow of water can enter the concave groove 711, so as to avoid the overflow of the water flow when the fan swings the head up and down.

[0032] Furthermore, referring to FIG. 7, a support bump 731 is further installed on the inner side wall of the water receiving groove 730. By supporting the side wall of the refrigeration package 600 with the support bump 731 so that a gap is formed between the refrigeration package 600 and the side wall of the water receiving groove 730, the water droplets condensed by the refrigeration package 600 can smoothly flow into the water receiving groove 730, avoiding the problem of overflowing from the side wall of the water receiving groove 730.

[0033] Furthermore, referring to FIGS. 3 and 5, the mount 700 is removably connected to the rear mesh 500. Specifically, a plurality of elastic buckles 701 are installed on one side of the mount 700, and a locking groove that engages with the elastic buckle 701 is installed on the rear mesh 500. The elastic buckle 701 engages with the locking groove to realize the removable connection between the mount 700 and the rear mesh 500.

[0034] Furthermore, referring to FIGS. 6 and 7, the mounting groove 720 includes two elastic arms 721 that are installed opposite to both sides of the outer ring side wall 713. At the free end of the elastic arm 721, a stopper portion 722 and a pressing portion 723 for stopping the refrigeration package 600 in the mounting groove 720 are installed. In this embodiment, the refrigeration package 600 can be clamped by the elastic force of the elastic arm 721, and the refrigeration package 600 can be fixed in the mounting groove 720. Also, when removing the mount 700, by making it easier for the user to hold the mount 700 with the pressing portion 723, the mount 700 can be easily removed from the rear mesh 500.

[0035] Furthermore, referring to FIGS. 4 and 5, the refrigeration package 600 includes a water tank 610 for storing ice or refrigerant. A water injection port 620 is installed in the water tank, and the through hole 601 is a honeycomb hole installed on the water tank 610. In this embodiment, water is injected into the water tank 610 through the water injection port 620, and then placed in the refrigerator and frozen to turn the water in the water tank 610 into ice.

[0036] 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.
