[0030] As shown in Figures 1 to 6 The embodiment of the present application is a tower fan, which comprises a shell, a fan assembly 80, a speed regulating assembly and a head shaking mechanism 40. The shell comprises a shell body 10, an air inlet grille 30 and an air outlet grille 20. The inside of the shell body 10 is formed with an airflow channel. The opposite surfaces of the shell body 10 are respectively provided with an air inlet and an air outlet which are in communication with the airflow channel. The air inlet grille 30 is arranged on the air inlet, and the air outlet grille 20 is arranged on the air outlet. The fan assembly 80 comprises a cylindrical fan 81 and a power component 82 which are arranged in the airflow channel from top to bottom. The output shaft of the power component 82 is connected with the lower end of the cylindrical fan 81, which is used to drive the cylindrical fan 81 to rotate, so as to accelerate the airflow in the airflow channel. The head shaking mechanism 40 is connected with the lower end of the shell body 10, which is used to drive the shell body 10 to swing. The speed regulating assembly comprises a speed regulating rod 60, a speed regulator 90 and a controller. The controller and the speed regulator 90 are arranged in the airflow channel and above the cylindrical fan 81. The controller is electrically connected with the speed regulator 90. One end of the speed regulating rod 60 is connected with the speed regulator 90, and the other end is arranged to pass through the top of the shell body 10, which is used to adjust the gear position of the speed regulator 90.

[0031] Exemplarily, the power member 82 is used to drive the cylinder fan 81 in the air flow channel, so that the external air can be accelerated to enter the air flow channel from the air inlet grille 30, and then be sent out through the air outlet grille 20, so as to guide the wind to the user more gently. In addition, the power member 82 can be a servo motor, so that the cylinder fan 81 can realize forward and reverse rotation, but is not limited thereto.

[0032] Exemplarily, the swing mechanism 40 is used to drive the shell 10 to swing left and right, so that the wind blown out from the air outlet grille 20 can have a wider air outlet angle, and thus the blowing range is wider. For this purpose, the swing mechanism 40 can be a power member commonly used in the prior art to drive the shell 10 to swing, and details are not described herein.

[0033] Exemplarily, the speed adjusting assembly is used to adjust the wind speed of the tower fan. Specifically, the speed adjusting device 90 is provided with a low speed gear, a medium speed gear and a high speed gear. If the wind speed of the tower fan is adjusted from low speed to medium speed, the speed adjusting lever 60 is moved to adjust the gear of the speed adjusting device 90 from the low speed gear to the medium speed gear, and then the controller controls the power member 82 to rotate faster to increase the rotating speed of the cylinder fan 81, so as to adjust the wind speed of the tower fan to medium speed. Similarly, the wind speed of the tower fan can be adjusted to the required wind speed by the above-mentioned method, and details are not described herein. It should be pointed out that the wind speed is adjusted by adjusting different gears of the speed adjusting device 90, which is a common means for those skilled in the art, and details can be referred to the prior art, and details are not described herein.

[0034] Based on the above technical features of the tower fan, the speed adjusting device 90 is arranged in the air flow channel in the shell 10, and one end of the speed adjusting lever 60 is connected to the speed adjusting device 90 and the other end extends from the top of the shell 10. When it is needed to adjust the wind speed of the tower fan in the on state, the speed adjusting lever 60 is manually moved to adjust the corresponding gear of the speed adjusting device 90, and the signal is transmitted to the controller, and then the controller controls the power member 82 to drive the cylinder fan 81 to rotate, so as to adjust the rotating speed of the cylinder fan 81, thereby adjusting the wind speed of the tower fan to the required wind speed. Compared with the conventional adjustment mode by the control panel, the above-mentioned adjustment mode can avoid misoperation in the rotating state, and provides a better interactive experience for the user.

[0035] In a possible implementation, the top of the shell 10 is provided with an arc-shaped opening 10b, and the end of the speed adjusting lever 60 away from the speed adjusting device 90 extends from the arc-shaped opening 10b to the outside of the shell 10. In this way, when the wind speed of the tower fan is adjusted, the speed adjusting lever 60 can be arc-shapedly rotated along the opening direction of the arc-shaped opening 10b, so as to facilitate the user to adjust.

[0036] In a possible implementation, the two ends of the arc-shaped opening 10b each extend into the interior of the housing 10 with an abutting block, the surface of the abutting block is concave with an arc-shaped slot, which is adapted to the rod body of the adjusting rod. In this way, during the process of adjusting the wind speed, the adjusting rod will be abutted by the abutting block, at this time, the rod body of the adjusting rod is attached to the arc-shaped slot, thereby avoiding the damage caused by the repeated collision of the adjusting rod with the two ends of the arc-shaped opening 10b.

[0037] In a possible implementation, the two inner sides of the arc-shaped opening 10b extend downward with two axisymmetrically arranged elastic arms, which are used to clamp the speed adjusting rod 60, so that the speed regulator 90 keeps the corresponding wind speed gear. In this way, after the adjusting rod is rotated to the required gear, the two elastic arms at the corresponding position will clamp the speed adjusting rod 60, thereby allowing the speed adjusting rod 60 to remain stationary, ensuring that the speed regulator 90 corresponds to the wind speed gear.

[0038] In a possible implementation, a timer 70 is further included, which is embedded in the top of the housing 10 and electrically connected with the controller. For example, when the user needs to set the timing time for turning on or off the tower fan, the timer 70 is used to automatically start or turn off the tower fan when the time arrives. The pre-appointment timing circuit meets the needs of the user to turn on or off the tower fan at a specific time of the day (e.g., turning on at 6 o'clock after work or turning off at 8 o'clock in the morning before leaving for work), making the use of the tower fan more humanized.

[0039] In a possible implementation, the surface of the housing 10 provided with the air inlet is concave with a first mounting position 11, the inner edge of the first mounting position 11 is spaced apart along the circumference with a plurality of first clamping openings 10c, and the surface of the air inlet grille 30 facing the housing 10 is provided along the circumference with a plurality of first clamping blocks 20a, which are matched with the first clamping openings 10c.

[0040] In a possible implementation, the surface of the housing 10 provided with the air outlet is concave with a second mounting position, the inner edge of the second mounting position is spaced apart along the circumference with a plurality of second clamping openings, and the surface of the air outlet grille 20 facing the housing 10 is provided along the circumference with a plurality of second clamping blocks, which are matched with the second clamping openings.

[0041] In a possible implementation, a base 50 is further included, which is connected with the swing mechanism 40, and the surface of the base 50 away from the housing 10 is provided with a plurality of reinforcing ribs 50a. That is, by connecting the base 50 with the ground, the contact area with the ground can be increased, ensuring the stability of the tower fan during use and avoiding the collapse affecting the use. In addition, the plurality of reinforcing ribs 50a provided on the surface of the base 50 away from the housing 10 can enhance the structural strength of the base 50, which can further ensure the stability of the tower fan.

[0042] In a possible implementation, the side surface of the shell 10 is provided with an air outlet hole 10a in communication with the air flow channel. In this way, the air flow in the air flow channel can be blown out from the air outlet hole 10a, and the air flow can be blown in multiple directions to meet different use requirements and improve the practicability.

[0043] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
