Description

Technical Field

[0001] This utility model belongs to the field of fan technology, and in particular relates to a fan for cooling food. Background Technology

[0002] In daily life, people have different temperature preferences for food. For example, many Japanese people prefer cooler food to hot food when eating. However, freshly cooked food is usually quite hot, and eating it directly may affect the taste and overall experience. Traditional cooling methods include natural cooling or using a refrigerator, but these methods are either time-consuming or may affect the texture and flavor of the food. Currently, there are no devices on the market specifically designed for cooling food. Utility Model Content

[0003] To address the shortcomings of existing technologies, a fan specifically designed for cooling food is provided.

[0004] This utility model is achieved using the following technical solution: a fan for cooling food, comprising:

[0005] The housing has an air inlet and an air outlet at its lower end;

[0006] Support legs, located at the lower end of the housing, are used to support the housing so that there is space below the air outlet for placing food; and

[0007] A fan, which is housed inside the casing and provides airflow through the outlet.

[0008] When in use, the user can turn on the fan and place the lunchbox containing the food at the bottom of the shell so that the air outlet is directed at the food to cool it down, which is very convenient.

[0009] This design incorporates a support leg beneath the fan-equipped casing, allowing the casing to suspend and creating a space below the air outlet for placing food. This space allows the lunchbox to be placed for cooling. The fan is also convenient to use, as it can be placed directly on a table without needing to be held by the user.

[0010] Preferably, the legs are folded together with the housing, and the legs can be folded to fit the side or bottom of the housing.

[0011] The above design allows users to fold the legs when the fan is not in use, reducing the space occupied by the entire device and making it easier to carry and store. The folding method can be hinged, scissor-type, or telescopic, etc. Hinged folding allows the legs to fold outwards or inwards, enabling them to fit against the side or bottom of the housing.

[0012] Preferably, there are two legs, which are located on both sides of the air outlet. The legs are hinged to the housing. When the legs need to be folded, they flip inward and fit against the bottom surface of the housing.

[0013] The hinged folding mechanism is more convenient for users.

[0014] Preferably, the hinged connection between the support leg and the housing is located at opposite sides of the lower end of the housing.

[0015] The above design allows for longer legs, which, when opened, increase the height of the casing, thus providing ample space underneath to place the lunchbox.

[0016] Preferably, a limiting structure is provided at the hinge joint between the support leg and the housing, the limiting structure being used to limit the extreme angle of outward rotation of the support leg.

[0017] By setting a limiting structure, the extreme angle of the outrigger rotation can be limited, ensuring the height of the outrigger when supporting the housing.

[0018] Preferably, when the support leg is rotated outward to its limit angle, the angle between the support leg and the housing is an obtuse angle.

[0019] The obtuse angle makes the support legs more stable for the housing, preventing the legs from rotating inward during use, and also allows for more space under the housing.

[0020] Preferably, the support leg is provided with a hinge shaft, the housing is provided with a hinge hole that mates with the hinge shaft, the side wall of the hinge shaft is provided with a C-shaped groove, and a limiting member is provided in the hinge hole. When the support leg rotates outward to the limit angle, the circumferential side wall of the C-shaped groove abuts against the limiting member to restrict the rotation of the hinge shaft; the limiting member and the C-shaped groove constitute the limiting structure.

[0021] Preferably, the air inlet is located at the upper end of the housing, and the air inlet of the housing is provided with a grille that is detachably connected to the housing. The housing has an upward-opening groove at the lower end of the grille, and a filter screen for filtering dust is provided in the groove.

[0022] The grille can compress the filter screen, and after a period of use, the grille can be opened to replace the filter screen. The filter screen has small ventilation holes and can be made of sponge, foam, fiber, etc. The grille can be detached by magnets, screws, or clips. Grooves are included to facilitate user adjustment of the filter screen's position when replacing it.

[0023] Preferably, the lower end of the support leg is provided with an anti-slip pad.

[0024] By adding anti-slip pads, the legs can be placed on the table without slipping.

[0025] Preferably, the housing also includes a power module and a control module, the control module of which can control the fan speed to adjust the wind speed.

[0026] Compared with the existing technology, this utility model has the advantages of being easy for users to carry and convenient for quickly cooling food. Attached Figure Description

[0034] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 4As shown, this embodiment discloses a food cooling fan, including a housing 1. An air inlet 41 is located at the center of the upper end of the housing 1, and an air outlet 42 is located at the center of the lower end of the housing 1. A fan 8 is housed inside the housing 1, positioned between the air inlet 41 and the air outlet 42. A control module and a power module are also provided inside the housing 1. The control module controls the fan speed of the fan 8, and the power module is used for charging and storing electricity. Both the control module and the power module are modules found in existing fans. The control module includes a button 5 located on the upper end of the housing 1; pressing the button 5 adjusts the fan speed of the fan 8.

[0036] The housing 1 has an upward-opening groove 11 with a rectangular inner edge at the air inlet 41, and a filter 6 is installed inside the groove 11. A grille 3 is provided above the groove 11, and a buckle 31 is provided at one end of the grille 3. The housing 1 has a buckle groove, and the buckle 31 engages with the buckle groove to achieve detachable fixing of the grille 3 and the housing 1. The grille 3 can confine the filter 6 inside the groove 11.

[0037] like Figures 1 to 6 As shown, hinge seats 7 are provided on the left and right edges of the lower end of the housing 1, and support legs 2 are hinged to the hinge seats 7. The support legs 2 are folded into the housing 1 through the hinge seats 7, and the two support legs 2 can be rotated inward and folded to fit against the bottom surface of the housing 1. When the support legs 2 are opened, they can support the housing 1, and the space between the two support legs 2 and the housing 1 is formed to place the lunch box. Anti-slip pads 21 are provided at the lower end of the two support legs 2. When the support legs 2 are rotated outward to their limit angle, the angle between the support legs 2 and the housing 1 is an obtuse angle.

[0038] The hinge base 7 includes an upper shell 71 and a lower shell 72, which together form a hinge hole 73. An upwardly extending limiting member 74 is provided on the lower shell 72. The support leg 2 is provided with a hinge shaft 22, which mates with the hinge hole 73. A C-shaped groove 23 is provided on the side wall of the hinge shaft 22. When the support leg 2 rotates outward to its limit angle, the circumferential side wall of the C-shaped groove 23 abuts against the limiting member 74 to achieve the limit angle of outward rotation of the support leg 2. Furthermore, in this embodiment, the limiting member 74 is also used for the insertion and fixing between the upper shell 71 and the lower shell 72.

[0039] When in use, the user opens the support leg 2 outwards and places it on the table, then presses button 5 to start the fan 8, and places the food that needs to be cooled under the housing 1. When not in use, press button 5 to turn off the fan 8, and then fold the support leg 2 inwards.
