[0088] Example 7:

[0089] This embodiment provides an easy-to-clean heater, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0090] The quick-release guide assembly 4 includes:

[0091] The guide vanes 40 are evenly distributed circumferentially on the inner wall of the arc plate 300;

[0092] The quick-release guide block 41 is located on the side of each guide plate 40 near the inner wall, and a quick-release guide rail 42 is provided on the inner wall along the length direction of the arc plate 300 for moving the quick-release guide block 41 back and forth.

[0093] The air guide vane 40 is used to guide the hot air entering the arc-shaped module 30, preventing air turbulence and ensuring that the hot air can be efficiently blown out from the air outlet, making the indoor heating more uniform and avoiding local overheating. The air guide vane 40 is usually a long strip-shaped thin sheet structure with a relatively smooth surface to reduce airflow resistance. One end is fixed to the quick-release guide block 41, and the other end extends towards the air outlet. The air guide vane 40 is evenly distributed circumferentially along the inner wall of the arc plate 300, installed on the quick-release guide block 41, located inside the arc-shaped module 30 near the air outlet, in the airflow path. The air guide vane 40 can be fixedly connected to the quick-release guide block 41 by welding, adhesive bonding, or other methods.

[0094] The quick-release guide block 41 connects the guide vane 40 to the quick-release guide rail 42, enabling quick installation and removal of the guide vane 40 and facilitating cleaning and maintenance. The quick-release guide block 41 is typically a block-shaped structure, with one side fixedly connected to the guide vane 40 and the other side having a shape adapted to the quick-release guide rail 42, allowing it to slide within the rail. The quick-release guide block 41 is installed on the side of the guide vane 40 near the inner wall of the arc plate 300, located within the quick-release guide rail 42, and can move along the length of the arc plate 300 within the rail. The quick-release guide block 41 and the quick-release guide rail 42 can be connected by a sliding fit, allowing for smooth movement within the rail.

[0095] In this embodiment, when hot air enters the arc-shaped module 30, the guide vane 40, with its special shape and installation angle, changes the direction of airflow, causing the hot air to flow evenly towards the air outlet. During the operation of the heater, the guide vane 40 remains in a fixed position, continuously guiding the airflow. When cleaning the quick-release guide assembly 4 is required, the user holds the guide vane 40 and pulls the quick-release guide block 41 outward along the quick-release guide rail 42 to remove the guide vane 40 from the arc-shaped module 30 for cleaning. After cleaning, the guide vane 40 is aligned with the quick-release guide rail 42 and inserted, and the quick-release guide block 41 slides into the guide rail, completing the installation.

[0096] Example 8:

[0097] This embodiment provides an easy-to-clean heater, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0098] The arc-shaped magnetic filter 5 includes:

[0099] The arc-shaped filter 50 corresponds one-to-one with the arc plate 300. The arc-shaped filter 50 is located in front of the guide plate 40, and the arc-shaped filter 50 can be spliced ​​together to form a ring structure.

[0100] A first arc-shaped magnetic strip 51 is disposed on the side of the arc-shaped filter 50 near the inner wall of the arc plate 300. A second arc-shaped magnetic strip 52 that attracts the first arc-shaped magnetic strip 51 is disposed on the inner wall of the arc plate 300 near the air outlet.

[0101] The arc-shaped filter 50 directly intercepts impurities such as dust, hair, and particulate matter in the air, purifying the air and ensuring that the air blown out of the heater is clean. The arc-shaped filter 50 is typically arc-shaped, with a mesh structure consistent with the arc plate 300, and is woven from metal wire or fiber material. The arc-shaped filter 50 is located inside the arc-shaped module 30, near the air outlet, and is installed on the first arc-shaped magnetic strip 51. In the airflow path, hot air passes through its mesh. The arc-shaped filter 50 and the first arc-shaped magnetic strip 51 can be connected by adhesive or by a clip.

[0102] The first arc-shaped magnetic strip 51 and the second arc-shaped magnetic strip 52 cooperate to fix the arc-shaped filter screen 50 to the inner wall of the arc plate 300 by magnetic force, while ensuring the stability of the filter screen during installation and use. The first arc-shaped magnetic strip 51 is usually arc-shaped and is a permanent magnet structure adapted to the shape of the arc-shaped filter screen 50 and the inner wall of the arc plate 300. It is installed on the side of the arc-shaped filter screen 50 near the inner wall of the arc plate 300, distributed along the edge of the filter screen, between the filter screen and the inner wall of the arc plate 300.

[0103] The second arc-shaped magnetic strip 52 attracts the first arc-shaped magnetic strip 51, working together to fix the arc-shaped filter 50 to the inner wall of the arc plate 300, maintaining the filter's installation state. Similar to the first arc-shaped magnetic strip 51, the second arc-shaped magnetic strip 52 is an arc-shaped permanent magnet structure, installed on the inner wall of the arc plate 300 near the air outlet, corresponding to the first arc-shaped magnetic strip 51, on one side of the inner wall of the arc plate 300 at the filter installation position. The second arc-shaped magnetic strip 52 can be connected to the inner wall of the arc plate 300 by adhesive bonding, slot fixing, or other methods.

[0104] In this embodiment, when hot air flows from inside the arc-shaped module 30 to the air outlet, dust, impurities, and other particles in the air are intercepted by the arc-shaped magnetic filter 5 because their size is larger than the filter mesh, thus achieving air purification. The arc-shaped filter 50 is fixed to the inner wall of the arc plate 300 by the magnetic force of the first and second arc-shaped magnetic strips 52, maintaining stability under the impact of airflow. When the filter needs to be cleaned, the user applies external force to overcome the magnetic force and remove the arc-shaped filter 50 from the inner wall of the arc plate 300. After cleaning, the filter is re-adsorbed and fixed to the inner wall of the arc plate 300 by the magnetic force of the magnetic strips.

[0105] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
