AI Technical Summary
In the existing technology, high-output electric blowers have insufficient performance under high output conditions.
By setting a partition inside the main body of the blower, the internal space is divided into a first space and a second space. The battery is installed in the first space, and the airflow generation part is located in the second space. The airflow is used to cool the battery through the partition, thereby improving the battery's cooling efficiency.
It improves operating performance at high output power and helps to reduce the size of the blower.

Abstract
Claims
1. A blower that operates by means of a battery, wherein, It has a main body; The main body has an outlet, an airflow generating section, and a partition wall section. The nozzle is located at the front of the main body. The airflow generating unit is configured to generate airflow from the rear of the main body toward the nozzle by supplying power from the battery within the interior space of the main body. The partition is configured to divide the interior space into a first space and a second space. The first space is configured to accommodate the battery. The second space is located outside the first space and is configured to allow the airflow to pass through.
2. The blower according to claim 1, wherein, The partition wall has a connecting hole. The connecting hole is configured to connect the first space and the second space.
3. The blower according to claim 2, wherein, The battery is configured to cover the connecting hole.
4. The blower according to claim 2, wherein, The battery has a casing. The outer casing has a first opening and a second opening, wherein, The first opening is configured to allow air to flow into the interior of the housing. The second opening communicates with the first opening and is configured to allow air flowing into the housing to exit. With the battery installed on the blower, the connecting hole and the second opening are positioned relative to each other.
5. The blower according to claim 2, wherein, The connecting hole is configured to be located on the upper side of the battery when the blower is in use.
6. The blower according to claim 5, wherein, The battery has connection terminals. The main body also has a battery mounting section. The battery mounting portion is configured as follows: It is electrically connected to the airflow generating unit and the battery can be installed and removed. With the battery installed in the battery mounting part, it is located on the side opposite to the communication hole relative to the battery and is connected to the connection terminal.
7. The blower according to claim 2, wherein, The battery has connection terminals. The main body also has a battery mounting section. The battery mounting portion is configured as follows: It is electrically connected to the airflow generating unit and the battery can be installed and removed. With the battery installed in the battery mounting part, it is located on the same side as the communication hole relative to the battery and is connected to the connection terminal.
8. The blower according to any one of claims 1 to 7, wherein, The main body also has an air intake hole. The air intake is opened in the wall portion at the rear of the main body and is configured to guide external air into the second space of the main body.
9. The blower according to any one of claims 1 to 7, wherein, The second space forms the entire surrounding space that encloses the first space. The main body also has an air intake hole. The air intake is opened in the wall portion at the rear of the main body and is configured to guide external air into the second space of the main body.
10. The blower according to any one of claims 1 to 7, wherein, The main body also has an air intake hole. The air intake is opened in the rear wall and the circumferential wall of the main body and is configured to guide external air into the second space of the main body.
11. The blower according to any one of claims 1 to 7, wherein, The airflow includes a first airflow and a second airflow. The first airflow is configured to pass through the first space. The second airflow is configured to pass through the second space.
12. The blower according to claim 11, wherein, The main body also includes a filter and is configured to guide the first airflow through the filter to the first space. The filter is configured to trap the objects contained in the first airflow.
13. The blower according to any one of claims 1 to 7, wherein, The airflow generating section is positioned forward of the partition section.
14. The blower according to any one of claims 1 to 7, wherein, The airflow generating unit is configured to generate the airflow via an axial fan.
