Description

TECHNICAL FIELD

[0001] The utility model belongs to fan technical field, concretely relates to a wearable portable fan. BACKGROUND

[0002] At present, portable fans on the market are various, such as neck-hanging type, handheld type, shoulder-coat type, etc., which can meet the basic needs of carrying and relieving heat, and are deeply loved by users.

[0003] For example, the existing neck-hanging fan device generally only has the function of blowing air to the neck of the human body, and the cooling part is limited. Therefore, a wearable temperature regulating device capable of blowing air to the back is disclosed in Chinese Patent No. CN219012919U, which defines a neck-wearing space. The wearable temperature regulating device capable of blowing air to the back includes a main body and a protruding part provided on the main body. The protruding part is provided on the first side of the main body, and the extension distance of the protruding part is greater than 15 mm. The protruding part can extend as far as possible towards the collar covering the back of the human body, and even can extend into the collar, so that the first air outlet of the protruding part can blow air to the back of the human body inside the collar, realizing the cooling and regulating needs of the back of the human body. However, the fan device is worn on the neck during use, and the rigid shell structure hung on the neck for a long time can easily cause neck soreness. In addition, the adaptability to people with different neck sizes is poor. The necks of small people are easy to shake, and the necks of large people are easy to contact with the neck, causing discomfort such as contact friction. Moreover, the fan body is close to the head after wearing, and the noise generated by the fan can also affect the user.

[0004] For example, Chinese Patent No. CN212899046U discloses a shoulder-hanging fan using air negative pressure airflow, which is internally fixedly connected with a negative pressure airflow fan structure, and the negative pressure airflow fan structure is composed of a first air blowing motor, a first rotating shaft, a first fan blade, an air inlet, a first negative pressure flow guide hole, a second negative pressure flow guide hole, a second motor, a second rotating shaft and a second fan blade. One end inner wall of the shoulder-hanging fan body is fixedly connected with the first air blowing motor. The shoulder-hanging fan is provided with the first negative pressure flow guide hole and the second negative pressure flow guide hole. When the first air blowing motor is turned on, air negative pressure will guide the airflow, so that the airflow enters the air inlet through the first negative pressure flow guide hole and the second negative pressure flow guide hole. The neck below the fan will have air inlet due to the airflow circulation, and the area below the fan will be very cool. At the same time, the wearing design of the shoulder-hanging type also solves the problem of discomfort caused by the neck-hanging fan worn on the neck. However, the air blowing motor is arranged at both ends, and the shell is provided with an air outlet corresponding to the neck position. Thus, only the neck has a cooling effect, and the back and other positions cannot be cooled. SUMMARY

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0027] The wearable portable fan disclosed in this utility model adopts a multi-directional air outlet design, which is convenient to carry and use. It can be used in various scenarios such as study, life and work, and can cool down users and improve comfort in hot weather.

[0028] like Figure 1 , 2 As shown, this utility model discloses a wearable portable fan, including a main body 100 and two wearable components 200 connected to the main body. The main body 100 includes a shell and a blower installed inside the shell. The shell is provided with an air inlet 101, a first air outlet 102, and two air duct connection ports 103. For easy assembly, the shell is assembled from a base 104 and a face cover 105.

[0029] The wearable component 200 includes a duct 201 and a bendable support strip 202. A second air outlet 203 is provided on the side wall of the duct, and a third air outlet 204 is located at the tail end of the duct. The duct 201 is made of a flexible material, specifically silicone or flexible PVC. A receiving tube 205 is provided on the duct 201 for mounting the support strip 202; the support strip passes through the receiving tube 205 for support and shaping. Specifically, the support strip 202 can be a bendable metal strip that can be shaped after bending. That is, the metal strip can bend under external force, and after bending, the support strip retains the bending effect due to the characteristics of the material or structure and does not spring back, thus shaping the support strip in a bent state. During assembly, the air inlet end of the duct is connected to the air duct connection port 103 via a connector 206.

[0030] Specifically, such as Figure 2 As shown, the connector 206 has a connecting hole 207, and a pin 107 is provided at the corresponding position of the air duct connection port 103. When the base 104 and the cover 105 are mated, the pin 107 can pass through the connecting hole 207 to fix the connector 206 to the housing. Of course, in addition to the above-mentioned slot structure, the connector 206 can also adopt other structural forms, such as... Figure 3 As shown, a slot 208 is provided on the connector 206. When the base 104 and the cover 105 are connected, the side wall at the air duct connection port 103 can be embedded in the slot 208 to lock the connector.

[0031] The wearable component structure of this invention allows for adjustment of its shape by bending the support strip, enabling it to be worn on the shoulder or around the waist. The support strip also allows for adjustment of the orientation of the second and third air outlets, achieving directional airflow. Thus, users can adjust the design according to their body size and desired airflow location, ensuring a comfortable fit and directional airflow.

[0032] Preferably, both the first air outlet 102 and the second air outlet 203 adopt a multi-hole arrangement design to provide gentle airflow. Additionally, to ensure smooth air intake, such as... Figure 4 As shown, the housing has an inwardly recessed groove 106, which has a "C"-shaped structure. Specifically, there can be one or more grooves. The air inlet 101 is located on the groove wall. During use, the groove provides air intake space. Thus, regardless of whether the main body 100 is used outside or inside clothing, the groove design prevents direct contact between the air inlet and the skin or clothing, avoiding blockage and promoting airflow for a good air intake effect.

[0033] Preferably, such as Figure 5 As shown, a partition 209 is also provided inside the duct 201. The partition 209 is connected inside the duct and divides the duct into a first air duct 210 and a second air duct 211. Specifically, the partition 209 can be an integral structure with the duct 201, directly manufactured by a one-piece molding method. Alternatively, it can be a separate structure, and then the partition and the duct are connected by adhesive or other fixing methods.

[0034] The second air outlet 203 consists of multiple air outlet holes spaced apart on the side wall of the first air duct, and the tail end outlet of the second air duct is the third air outlet 204. This design, by setting baffles to separate the air ducts, can divert the air entering the air duct, ensuring the air volume of the third air outlet 204.

[0035] In addition, the fan structure disclosed in this utility model can be worn on the shoulder or waist. When used as a shoulder hanger, the main body 100 of the fan is located on the back, and when used as a waist wrap, the main body 100 of the fan is located on the waist. In both ways, the fan components that generate noise are relatively far away from the user's ears, and the user experience is better than that of traditional neck hangers.

[0036] Furthermore, when the wearable portable fan of this invention is worn around the waist, since different users have different waist sizes, if a user with a large waist size uses it, the wearing form is limited by the length of the two wearable components, and the wearing form is a semi-circular one. Therefore, in order to better ensure stability after wearing, the support bars 202 of the two wearable components 200 are respectively connected to the connecting joints by elastic ropes 212, and the two connecting joints can be connected and fixed.

[0037] like Figure 6 As shown, the support bar 202 can be a pipe structure, with an elastic rope 212 installed inside the pipe and one end fixed to the support bar, the other end fixedly connected to the connecting joint. Preferably, the connecting joint on one of the wearable components is a first connecting joint 213, and the connecting joint on the other wearable component is a second connecting joint 214. Further, the first connecting joint 213 is provided with a plug, and the second connecting joint 214 is provided with a slot, so that the plug and slot can engage and lock together when mated. To ensure a better connection effect, the first connecting joint 213 and the second connecting joint 214 also have built-in magnets or are made of magnetic materials, so that they can also attract each other when mated, preventing the plug and slot from detaching during use.

[0038] In this embodiment, the hair dryer includes a rechargeable battery 108, a circuit board 109, and a fan assembly. A switch and a charging interface are connected to the circuit board 109. During assembly, the rechargeable battery and fan assembly are mounted on the base 104. A window 110 adapted to the charging interface is provided on the cover 105. The circuit board 109 is fixedly mounted on the cover 105, with the charging interface inserted into the corresponding window 110. A switch drive rod 124 is also mounted on the cover 105, allowing for switch control.

[0039] Specifically, such as Figure 6 As shown, the fan assembly can adopt the following structure: it includes a first motor 111, a first fan blade 112, a second fan blade 113, and a third fan blade 114. A first driving gear 115 is connected to the output shaft of the motor 111, and a slot is provided on the first driving gear 115. The first fan blade 112 is connected to a first driven gear 117 via a first rotating shaft 116. The second fan blade 113 is connected to a second driven gear 119 via a second rotating shaft 118. The third fan blade 114 is connected to one end of a third rotating shaft 120, and the other end of the third rotating shaft 120 is fitted into the slot of the first driving gear 115. During installation, the end of the third rotating shaft 120 is inserted into the slot, and the two are connected and fixed by a fixing pin. The first rotating shaft 116 and the second rotating shaft 118 are respectively mounted on the housing via support base 122, and a limiting plate 123 is provided in front of the first driven gear 117 and the second driven gear 119; both the support base 122 and the limiting plate 123 are formed by the connection of two parts set on the base 104 and the cover 105. When the motor 111 is started, it can drive the first fan blade 112, the second fan blade 113 and the third fan blade 114 to rotate simultaneously. The rotation of the third fan blade 114 blows the air towards the first air outlet 102 for discharge. The first fan blade 112 and the second fan blade 113 blow the air into the air duct of the corresponding wearable component, and then discharge it through the second air outlet 203 and the third air outlet 204. Multiple air outlets work simultaneously to cool different parts of the user's body.

[0040] In addition, such as Figure 7 , 8 As shown, the fan assembly can also adopt the following structure: the fan assembly includes two centrifugal fans respectively installed at the connection ports of two air ducts; the centrifugal fans consist of a second motor 125 and a centrifugal impeller 126. When the centrifugal fans start, part of the airflow generated is sent into the corresponding air ducts and discharged from the second and third air outlets. Part of the airflow is blown towards the first air outlet on the casing and discharged. Multiple air outlets operate simultaneously to cool different parts of the user's body.

[0041] The above description sets forth many specific details to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein, and therefore should not be construed as limiting the scope of protection of the present invention.

[0042] In summary, although the present invention has listed the above preferred embodiments, it should be noted that although those skilled in the art can make various changes and modifications, such changes and modifications should be included within the protection scope of the present invention unless they deviate from the scope of the present invention.
