Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower fans, and specifically to a novel tower fan. Background Technology
[0002] In the sweltering summer, fans have long been an indispensable household appliance for people to escape the heat. There are many types of household fans, but tower fans are particularly popular due to their small size, gentle airflow, and ability to provide various airflow modes. Tower fans work by rotating an internal impeller (usually cylindrical), which forces air through a cross-flow fan to create an airflow. This airflow is then distributed through internal air guide walls, forming a three-dimensional "wind wall" perpendicular to the ground and capable of oscillating left and right. Tower fans generally consist of a casing, impeller, and motor. The casing has an inlet grille and an outlet grille. Air is drawn in by the impeller through the inlet grille. However, because the impeller blades are close to the inlet grille, there is a safety hazard as children may insert their fingers into the grille and come into contact with the blades. Furthermore, the fan at the bottom of the impeller has poor heat dissipation.
[0003] Therefore, in order to overcome the shortcomings of existing technologies, a new type of tower fan with a simple structure needs to be designed. Utility Model Content
[0004] This invention provides a novel tower fan to address the problems of existing technologies.
[0005] The objective of this utility model can be achieved through the following technical solution: A novel tower fan includes: an outer shell and an inner cover, a wind turbine, and a power assembly located inside the outer shell. The rear end of the outer shell is provided with a horizontally arranged air inlet grille. The inner cover is disposed inside the outer shell and has a receiving cavity inside. The upper and lower ends of the inner cover are provided with vertical channels communicating with the receiving cavity. The vertical channels are connected to the air inlet grille. The wind turbine is disposed inside the receiving cavity. The power assembly is connected to the lower end of the wind turbine and fixed to the bottom of the outer shell.
[0006] In a further improvement, the inner cover includes a cover body one and a cover body two. The upper and lower ends of the cover body one and the cover body two are fixedly connected to the inside of the outer shell by screws. The cover body one is provided with a buckle, and the cover body two is provided with a locking block. The locking block is inserted and connected to the buckle.
[0007] In a further improvement, the inner side of the first cover is provided with an upper protrusion, and the inner side of the second cover is provided with a lower protrusion, with the upper protrusion and the lower protrusion in contact.
[0008] In a further improvement, the housing includes a front housing, a rear housing, a base, and a top cover. The front housing and the rear housing are mounted on the base and are fixedly connected by screws. The top cover is located at the upper end of the front housing and the rear housing. The air intake grille is located on the rear housing, and the rear housing is provided with a handle groove.
[0009] Compared with the prior art, the beneficial effects of this novel tower fan are as follows:
[0010] Air enters through the air intake grille at the rear of the outer casing, flows inward into the vertical channels on the upper and lower sides of the inner cover, and is then blown out through the other side of the impeller. By optimizing the air duct structure, it can prevent children from inserting their fingers into the air intake grille and touching the impeller, thus improving the safety of use. At the same time, the process of air being drawn in from the vertical channel on the lower side can dissipate heat from the power components below, reducing the temperature of the motor in the power components.

Detailed Implementation
[0016] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] The following describes the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.
[0019] Example 1
[0020] A novel tower fan includes: an outer shell 1 and an inner cover 2, a fan wheel 3, and a power assembly 4 located inside the outer shell 1. The rear end of the outer shell 1 is provided with a horizontally arranged air inlet grille 11. The inner cover 2 is disposed inside the outer shell 1 and has a receiving cavity 21 inside. The upper and lower ends of the inner cover 2 are provided with vertical channels 22 communicating with the receiving cavity 21. The vertical channels 22 are connected to the air inlet grille 11. The fan wheel 3 is disposed inside the receiving cavity 21. The power assembly 4 is connected to the lower end of the fan wheel 3 and fixed to the bottom of the outer shell 1.
[0021] like Figures 1-4 As shown, the working principle of this utility model is as follows: When the power component 4 in the tower fan drives the impeller 3 to work, air is drawn in. Specifically, the air enters from the air intake grille 11 at the rear end of the outer casing 1, flows inward to the vertical channels 22 on the upper and lower sides of the inner cover 2, and then blows the air out through the other side of the impeller 3. By optimizing the air duct structure, it can prevent children from inserting their fingers into the air intake grille 11 and touching the impeller, thus improving the safety of use. At the same time, the process of air being drawn in from the vertical channel 22 on the lower side can dissipate heat from the power component 4 below, reducing the temperature of the motor in the power component.

The upper protrusion 231 and the lower protrusion 241 are arranged in contact, which increases the contact area and stability between the cover 23 and the cover 24.
[0024] As a further preferred embodiment, the outer casing 1 includes a front casing 12, a rear casing 13, a base 14, and a top cover 15. The front casing 12 and the rear casing 13 are mounted on the base 14 and are fixedly connected by screws. The top cover 15 is located at the upper end of the front casing 12 and the rear casing 13. The air inlet grille 11 is located on the rear casing 13, and the rear casing 13 is provided with a handle groove 16. The components of the casing are fixedly connected by screws, making the overall appearance of the tower fan neater and more aesthetically pleasing. The components fixed by screws are easy to disassemble and repair, increasing the product's service life and maintenance convenience. The air inlet grille 11 is located on the rear casing 13, and the rear casing 13 is also provided with a handle groove 16 for easy handling by the user.
