Description

Technical Field

[0001] The present application relates to the field of air heaters, and in particular to a vertical air heater. Background Art

[0002] Heaters are widely used. Generally, vertical heaters are placed upright on the floor of a room. They do not require additional fixing methods, so they are relatively easy and quick to install. During the installation of this type of vertical heater, attention should be paid to its stability after being placed on the floor of the room. It is necessary to avoid unstable installation with the floor as much as possible, and avoid shaking.

[0010] In some embodiments, the angle between the two side edges of the fan-shaped rotating base is greater than 90 degrees.

[0011] In some embodiments, when one side of the sector of the rotating base contacts the micro switch, the other side of the sector of the rotating base forms an angle with respect to the bottom end surface of the bottom cover.

[0012] In some embodiments, a limiting plate is provided in the middle of the fan-shaped arc edge of the rotating base.

[0013] In some embodiments, the base includes a first base shell and a second base shell that are clamped together. Split grooves are respectively provided on opposite sides of the first base shell and the second base shell.

[0019] The following is combined with Figure 1 , 2 This application is described in further detail.

[0020] The present application embodiment discloses a vertical air heater, referring to Figure 1 , 2 , including a shell, the shell includes a shell body 1 and a bottom cover 2, the bottom cover 2 is installed at the bottom of the shell body 1, and an installation compartment 3 is formed between the shell body 1 and the bottom cover 2. An on-off switch assembly for ensuring that the heater is in an upright state is arranged in the installation compartment 3; the on-off switch assembly includes a rotating pressure piece and a micro switch 4 electrically connected to the heater electric control circuit, the micro switch 4 is installed in the installation compartment 3, and the rotating pressure piece is rotatably installed on the bottom cover 2 and is located on one side of the micro switch 4.

[0021] To facilitate the rotating installation of the rotating pressure piece, a rotating hole 5 is provided on the bottom cover 2, and the rotating pressure piece is rotatably installed at the rotating hole 5. When the heater is not placed on the ground, part of the rotating pressure piece is exposed on the side of the bottom cover 2 away from the shell body 1. In this embodiment, the rotating pressure piece includes a fan-shaped rotating base 6, and the rotating axis of the rotating base 6 is arranged at the angle between the two side edges of the fan. The angle between the two side edges of the fan of the rotating base 6 is greater than 90 degrees. A limiting plate 7 is provided in the middle of the fan-shaped arc edge of the rotating base 6. On the one hand, the limiting plate 7 has the function of limiting the maximum stroke of the rotating base 6 in the installation bin 3.

[0022] Normally, the maximum stroke range of the rotating base 6 around the rotating axis is located in the area where the microswitch 4 contacts the limit plate 7 and the edge of the rotating hole 5 of the bottom cover 2. When one of the fan-shaped sides of the rotating base 6 conflicts with the microswitch 4, it indicates that the heater has been stably placed on the ground without tipping over. In order to ensure that the rotating base 6 can contact the microswitch 4 after the heater is stably placed on the ground, the other fan-shaped side of the rotating base 6 forms an angle with the bottom end surface of the bottom cover 2. This allows the angle between the other fan-shaped side of the rotating base 6 and the fan-shaped arc side to always have a force that conflicts with the ground. When the heater is not placed stably or is tipping over, the force will disappear, and the conflicting relationship between the microswitch 4 and the rotating base 6 will also disappear accordingly. At this time, the heater will disconnect the internal circuit connection to avoid unnecessary safety hazards.

[0023] In order to ensure the stability of the installation of the heater, a base can be installed at the bottom of the shell, and a mounting groove 11 adapted to the bottom cover 2 is provided on the base. The base includes a first base shell 8 and a second base shell 9 that are clamped to each other. Split grooves 10 are respectively provided on the opposite sides of the first base shell 8 and the second base shell 9. After the first base shell 8 and the second base shell 9 are clamped to each other, the two split grooves 10 form the mounting groove 11; a through hole 12 corresponding to the position of the rotating pressure piece is provided at the bottom of one of the split grooves 10.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
