DETAILED DESCRIPTION
[0034] The present application is further described in detail below with reference to the accompanying drawings.
[0035] A one-piece handheld fan, referring to Figure 1 and 3 , comprises a shell 1, a fan 2, a motor 3, a display screen module 4, and a control assembly 5. The shell 1 is hollow inside to form an air duct 11, the fan 2, the motor 3, and the display screen module 4 are all installed inside the air duct 11, and the control assembly 5 is installed inside the handle of the shell 1. The inner side of the air duct 11 is also provided with a mounting rack 15 connected to the shell 1, the display screen module 4 and the motor 3 are respectively installed on both sides of the mounting rack 15, and the fan 2 is installed on the motor 3, so as to fix and install the fan 2 in the middle of the air duct 11, the fan 2 sucks air flow from one end of the air duct 11 and blows the air flow out from the gap between the display screen module 4 and the air duct 11. The display screen module 4 comprises a display screen body 41 and a panel 42, the display screen body 41 is installed on the outer side of the mounting rack 15, and the panel 42 is installed on the inner side of the display screen body 41. In the remaining embodiments, the display screen module 4 can be replaced by a refrigeration module, an atomization module, an illumination module, etc., which is installed on the mounting rack 15 by replacing the display screen module 4, so as to realize different functions.
[0036] Referring to Figure 2 , 5And 6, the part of the shell 1 located outside the air duct 11 is provided with an annular cavity 12, and the shell 1 can be split into a front shell 13 and a rear shell 14, and the air duct 11 and the annular cavity 12 are formed by splicing the front shell 13 and the rear shell 14. The annular cavity 12 can buffer the vibration generated during the rotation of the fan 2, thereby improving the use experience of the handheld fan 2 during the handheld process. The annular cavity 12 is provided with a reinforcing rib 121 inside, and the reinforcing rib 121 is respectively arranged on the inner side of the front shell 13 and the inner side of the rear shell 14. The reinforcing rib 121 located on the inner side of the front shell 13 connects the side wall of the annular cavity 12 and the inner wall of the front shell 13, and the reinforcing rib 121 located on the inner side of the rear shell 14 connects the side wall of the annular cavity 12 and the inner wall of the rear shell 14, thereby strengthening the strength of the shell 1. The edge of the front shell 13 located outside the annular cavity 12 is provided with a mounting groove 131, and the edge located inside the annular cavity 12 is provided with a limiting groove 135, and the mounting groove 131 is provided with a glue overflow groove 132 close to the side edge of the annular cavity 12, and the glue overflow groove 132 is communicated with the mounting groove 131 and the annular cavity 12. The edge of the rear shell 14 located outside the annular cavity 12 is provided with a mounting protrusion 141, and the edge located inside the annular cavity 12 is provided with a limiting protrusion 145, and the mounting groove 131 corresponds to the mounting protrusion 141. The connection mode of the front shell 13 and the rear shell 14 can be ultrasonic welding or gluing. If ultrasonic welding is used, the mounting protrusion 141 is welded with the mounting groove 131. If gluing is used, after the adhesive is applied, the mounting protrusion 141 is pressed into the mounting groove 131. The glue overflow groove 132 plays a role in glue overflow during the ultrasonic welding or gluing process. During the ultrasonic welding or gluing process, the excess glue overflows from the glue overflow groove 132 and flows into the annular cavity 12. Since the annular cavity 12 is isolated from the air duct 11 and the fan 2 outside, the overflowed adhesive will not affect the operation of the fan 2. The limiting groove 135 is formed by the concave part of the inner edge on the front shell 13 inside the annular cavity 12 and the protruding part of the reinforcing rib 121 on the front shell 13, and is circumferentially arranged. The limiting groove 135 on the front shell cooperates with the inner edge of the rear shell 14 inside the annular cavity 12 to ensure accurate and close connection of the front and rear shells. The limiting protrusion 145 on the inner edge of the rear shell 14 contacts the groove bottom plane of the limiting groove 135 and plays a role in welding in the ultrasonic welding connection mode. In addition, the annular cavity 12 can be filled with sound insulation, refrigeration, shock absorption and other materials to play a role in noise reduction, refrigeration air and shock absorption.
[0037] Referring to Figure 5 And 6The front shell 13 is further provided with a limiting hole 133, and the rear shell 14 is correspondingly provided with a limiting column 142, which can be inserted into the limiting hole 133 when the front shell 13 and the rear shell 14 are attached. The front shell 13 is further provided with a limiting rib 134, which protrudes from the front shell 13 and abuts the inner side of the rear shell 14 when the front shell 13 and the rear shell 14 are attached, so that the front shell 13 and the rear shell 14 are accurately attached. The front shell 13 is further provided with a button 136 protruding from the surface of the front shell 13, which is used for external operation of the handheld fan.
[0038] With reference to Figure 3 and 4 At the air inlet of the air duct 11, an air inlet net 16 and a pressing ring 17 are further provided. The air inlet net 16 can be provided with a mesh structure of different shapes, and the embodiment is a honeycomb structure. The air inlet net 16 is provided with a positioning hole 161, and the pressing ring 17 is provided with a buckle 171. The rear shell 14 is provided with a buckle position hole 143 and a positioning rod 144 on the outer side of the air duct 11. The positioning rod 144 corresponds to the positioning hole 161, so that the air inlet net 16 can be accurately installed on the outer side of the air duct 11. The buckle 171 can be buckled with the buckle position hole 143, so that the pressing ring 17 can press the air inlet net 16 at the inlet of the air duct 11, and the installation of the air inlet net 16 is completed.
[0039] With reference to Figure 3 The control assembly 5 includes a control panel 51 and a power supply 52. The control panel 51 is installed on the inner side of the handle part of the shell 1, and the power supply 52 is connected to the control panel 51, thereby providing power for the use of the control panel 51 and the fan 2.
[0040] With reference to Figure 5 The inner side of the mounting bracket 15 is provided with a communication groove 151, and the upper part of the communication groove 151 is provided with a communication port 152 which communicates between the two sides of the mounting bracket 15. The communication groove 151 communicates the control panel 51 and the communication port 152, so that the control panel 51 can be connected to the panels 42 and the motor 3 on both sides of the mounting bracket 15 through wires, thereby enabling the control panel 51 to control the operation of the fan 2 and the display of the display screen body 41.
[0041] The implementation principle of the embodiment is that the annular cavity 12 is provided on the outer side of the air duct 11, so that the vibration generated when the fan 2 installed in the air duct 11 rotates can be buffered. During the installation of the shell 1, the overflow port communicates the installation groove 131 and the annular cavity 12, so that the adhesive squeezed by the installation groove 131 and the installation protrusion 141 can overflow from the overflow port and enter the annular cavity 12, without remaining in the air duct 11 or the shell 1.
[0042] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, wherein the same parts are denoted by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
