[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0027] See Figures 1-6 A handle structure includes a handle body 1, which includes a column unit 2 and an upper shell 3. The upper shell 3 is installed on the upper end of the column unit 2, and the lower end of the column unit 2 has a base 21 for inserting a lithium battery. The base 21 is provided with an interface end (not shown in the figure) for cooperating with the lithium battery so that electrical energy can be output through the interface end after the lithium battery is inserted. The specific form of the interface end can refer to the existing design, which is used for the conduction of electrical energy.

[0028] For the column unit 2, it includes a receiving cavity for accommodating the resistor 4. In this embodiment, the column unit 2 is assembled from a first column 22 and a second column 23. The first column 22 includes a mounting position 221 for mounting the resistor 4, such as... Figure 4 As shown, resistor 4 can be mounted at mounting position 221, which can limit resistor 4 in the longitudinal direction. As one option, mounting position 221 can be as follows: Figure 4 The pattern shown is as follows: four positioning blocks are distributed in a square, corresponding to the four corners of resistor 4.

[0029] The second column 23 includes a limiting member 231 for pressing the resistor 4. The limiting member 231 laterally limits the resistor 4. After the first column 22 and the second column 23 are assembled, the limiting member 231, acting as the pressing member, laterally limits the resistor 4. Together with the mounting position 221, the resistor 4 is stably positioned within the column unit 2. This structure also facilitates the assembly and disassembly of the resistor. As one option, the limiting member 231 can be specifically as follows: Figure 5 As shown, it is cross-shaped and is formed by the outward protrusion of the inner wall of the second column 23.

[0030] In this embodiment, the upper shell 3 includes an inner cavity 31 for accommodating a motor (not shown in the figure) and an opening 32 in fluid communication with the inner cavity 31. A base 5 is installed at the opening 32. The base 5 is fixed to the upper shell 3 by fasteners. The base 5 is specifically used to assemble a fan guard, that is, an outer cover structure with an air outlet that includes the fan blades, as in the existing design.

[0031] In this embodiment, after the base 5 is installed on the upper shell 3, it can cover the opening 32 to hide the motor inside. At the same time, the base 5 has a through hole 51 in the middle for the motor shaft to pass through, so that the motor shaft can be connected to the fan blades to drive the fan to run and blow air.

[0032] In this embodiment, the upper shell 3 is also provided with a mating hole 33 that is in fluid communication with the inner cavity 31. The upper end of the column unit 2 is inserted into the upper shell 3 through the mating hole 33, that is, the inner cavity 31 can at least accommodate the motor and the upper end of the column unit 2.

[0033] Furthermore, the upper shell 3 also has several first mounting holes 34, and correspondingly, the upper end of the column unit 2 is provided with a second mounting hole 24 corresponding to the first mounting holes 34, so as to position the upper shell 3 and the column unit 2 by fasteners passing through the first mounting holes 34 and the second mounting holes 24.

[0034] In one embodiment, the first column 22 and the second column 23 are respectively provided with corresponding second mounting holes 24. At the same time, the upper shell 3 is provided with two first mounting holes 34 arranged on the left and right sides. After the upper end of the column unit 2 is inserted into the upper shell 3, the first mounting hole 34 and the second mounting hole 24 correspond one-to-one. After a bolt passes through the first mounting hole on the left side, the second mounting hole on the left side, the second mounting hole on the right side, and the first mounting hole on the right side in sequence, it is threaded with a nut to lock the upper shell 3 to the upper end of the column unit 2. Of course, a groove for accommodating and positioning the nut can also be designed at the first mounting hole on the right side.

[0035] In this embodiment, the interface is electrically connected to the control switch located on the handle body 1 via line three. The control switch then divides the connection into line one and line two. Both line one and line two are ultimately electrically connected to the motor. Resistor 4 is located on line one, while no resistor is located on line two. This means that when the control switch is switched to line one and power (such as a lithium battery) is supplied to the motor, the power supply must pass through the resistor; when the control switch is switched to line two and power is supplied to the motor, the power supply does not pass through the resistor, making it a direct-flow line. Figure 6 As shown.

[0036] The different resistance values ​​on different lines cause the motor speed to change accordingly, thereby adjusting the wind speed as strong wind and weak wind settings.

[0037] The control switch can be installed on the column unit 2 or the upper shell 3 as needed. For example, a hole can be made on the column unit 2 to install the control switch and expose the toggle position of the control switch. The control switch can be a toggle switch, push button switch or other switches commonly used in the prior art.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
