This is how air coolers and heaters have gradually entered many households around the world, becoming an indispensable home appliance in some regions. However, current air coolers and heaters have relatively small maximum airflow output, making it difficult to cover distant areas. Their overall vibration isolation effect is also generally poor, and they tend to produce abnormal noises after prolonged use.

[0003] Therefore, this utility model designs a bladeless fan for both cooling and heating. Utility Model Content

[0004] The purpose of this invention is to provide a bladeless fan for both cooling and heating, in order to solve the problems mentioned in the background art.

[0006] Preferably, the interior of the air duct is an elliptical arc structure, and the top of the arc-shaped air guide plate extends to be flush with the top of the corresponding air duct.

[0007] Preferably, the main housing has a slot for engaging and installing the filter cartridge, and the edge of the filter cartridge is engaged and installed in the slot.

[0008] Preferably, the shape and size of the interface at the top of the air supply seat match the shape and size of the corresponding air duct.

[0009] Preferably, the main housing is also provided with a monitoring sensor for monitoring ambient air.

[0010] Preferably, the main housing is a split structure, and the split structure of the main housing is assembled by snap-fit ​​and slot.

[0011] Preferably, the fan includes a main fan housing that is fixedly connected to the base by connecting screws, and the connecting screws are fitted with rubber rings for shock absorption. A drive motor is fixedly installed inside the main fan housing by a motor mounting plate. A synchronously rotating drum fan blade is installed at the output end of the drive motor. The motor mounting plate is provided with a shock-absorbing rubber ring that isolates the drive motor from vibration and the main fan housing from vibration.

[0012] Preferably, the two independent air outlets at the top of the air supply seat are fitted with anti-vibration pads for sealing and shock absorption. The air supply seat is connected to the main housing by screws, and the connecting screws are fitted with anti-vibration rubber sleeves for vibration isolation. The top of the main housing of the fan is connected to the bottom of the air supply seat by screws, and the connection between the main housing of the fan and the air supply seat is provided with air duct anti-vibration pads for sealing and vibration isolation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The bladeless fan designed in this utility model places the fan inside the main housing, delivers air to the air duct through the air supply seat, and then discharges it from the air outlet at the front end. The overall air output is more uniform and safer.

[0015] By designing an arc-shaped air guide plate at the top of the air duct, the air is guided to be transported along the arc-shaped air guide plate to the air outlet. Through the heating module, the warm air is transported from the air outlet to a greater distance, thus improving the heat preservation effect.

[0016] By incorporating a filter cartridge with an inner filter element inside the air inlet, dust and other contaminants in the incoming air can be filtered out, thus improving the quality of the delivered warm air.

[0017] By installing rubber shock-absorbing structures at the connection points between the fan and the base, the connection points between the fan and the air supply seat, and the interface between the top of the air supply seat and the air duct, as well as adding vibration isolation structures at the motor mounting point inside the fan, the entire cooling and heating fan achieves good shock absorption and sealing effects, avoiding problems such as abnormal noise caused by vibration.
