Problems solved by technology
[0006] (1) Since the annular nozzle and the fan motor with the largest total volume of the bladeless fan must be arranged at different heights in the direction of gravity, it is difficult to reduce the overall height of the bladeless fan, which greatly limits the usage scenarios of the bladeless fan
[0007] (2) The middle of the annular nozzle is hollow, and this area is not fully utilized, resulting in a waste of the overall volume of the fan, and an increase in the cost of product transportation and product storage
[0008] (3) Since the position of the air inlet of the fan motor is lower, it is easier to inhale the dust on the ground when inhaling, which increases the load on the filter screen and requires more frequent replacement of the filter screen, which significantly increases the size of the bladeless fan. cost of use
The filter screen is sealed between the downstream three-dimensional sealing strip and the mesh liner. The cost of the three-dimensional sealing strip is extremely high, and the sealing effect is poor after long-term use
[0010] (5) When replacing the filter screen, it is necessary to disassemble the two shells and replace the filter screens and then install them back. The process is cumbersome and the user-friendly experience is poor.
[0011] (6) It is difficult to add other functional modules to the product, and the scalability is poor

The invention provides a fan comprising a body and a nozzle. The body comprises an air inlet, an air outlet and a fan motor assembly for generating an air flow, and the air flow passes through the body in a first direction; and the nozzle is connected to the air outlet and used for receiving the air flow from the body and emitting the air flow, the air flow enters the nozzle, and the air flow is emitted out of the nozzle after moving at least based on a second direction opposite to the first direction. According to the fan, the moving direction of the air flow in the fan can be changed, the overall height of the fan is reduced, the overall volume is reduced, the service life of a filter screen is prolonged, and the use cost is reduced.
Description
technical field [0001] The present invention relates to the field of air conditioning equipment, in particular to fans. Background technique [0002] With the continuous improvement of life and technological level, people's requirements for quality of life are increasing day by day, and indoor air quality has become an important issue that people care about. Especially with the emergence of smog and PM2.5 problems in recent years, people's demand for air purifiers is also increasing. [0003] Air purifiers are small household appliances used to purify indoor air, mainly to solve the problem of indoor air pollution caused by decoration or other reasons. Since the release of pollutants in indoor air is characterized by persistence and uncertainty, the use of air purifiers to purify indoor air is an internationally recognized method to improve indoor air quality. There are many different technologies and media in an air purifier that enable it to provide clean and safe air to...
