Description

Technical Field

[0001] The utility model relates to a shoe drying device. Background Art

[0002] The shoe dryer is used to dry shoes, and its general structure is as follows: it includes a main body, in which a fan, an electric heater, an air duct, and a drying arm rotatably connected to the main body are arranged, and the drying arm is connected to the air duct. The electric heater is located behind the fan, and the wind blown by the fan enters the air duct after passing through the electric heater and finally blows to the drying arm. In order to make the wind blown by the fan form hot air with a certain temperature after passing through the electric heater, the electric heater adopts a PTC heating component, and the PTC heating component is a PTC heating component with corrugated heat sinks that is more common in the prior art, so that the wind blown by the fan passes through the space between the corrugated heat sinks, so that the wind blown by the fan can become hot air with a certain temperature.

[0003] The existing shoe dryers have the following disadvantages: 1. Even if a PTC heating component with a corrugated heat sink is used, since the electric heater is arranged in the main body, the hot air after passing through the PTC heating component and being transported to the drying arm in the air duct will still cause heat loss; 2. A PTC heating component with a corrugated heat sink must be used, which is relatively expensive. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the existing shoe dryers, the utility model provides a shoe dryer which can better deliver hot air and reduce costs.

[0005] The utility model solves the technical problem by providing a shoe drying device, comprising a main body, a hollow drying arm, an electric heating device, a fan, and a control circuit board for controlling the electric heating device and the fan, wherein the drying arm is arranged outside the main body, the fan and the control circuit board are arranged in the main body, an air inlet is arranged on the main body, and an air outlet is arranged on the drying wall;

[0006] The electric heating device is arranged in the drying arm, and the electric heating device corresponds to the air outlet;

[0007] The main body is also provided with an air duct connected to the blow-out outlet of the fan, and the air duct is also connected to the drying arm.

[0008] Furthermore, a heat sink is provided in the drying arm, and the electric heating device is attached to the heat sink.

[0009] Furthermore, the drying arm is rotatably arranged on at least one side of the main body.

[0010] Furthermore, the main body is provided with a fixed sleeve, the drying arm is provided with a movable sleeve, and the movable sleeve is sleeved outside the fixed sleeve.

[0011] Furthermore, the electric heating device is connected to the control circuit board via a wire, and the wire passes through the fixed sleeve and the movable sleeve.

[0012] Furthermore, the end of the air duct forms the fixed sleeve.

[0013] Furthermore, a limiting interlayer is provided on the outer side wall of the movable sleeve, and a limiting rib is provided on the main body, and the limiting rib extends into the limiting interlayer.

[0014] Furthermore, the movable sleeve is provided with a limiting member fixed in the main body outside, and the limiting member is provided with a blocking block; the movable sleeve is provided with a limiting block, and the drying arm can be rotated until the limiting block abuts against the blocking block.

[0015] Furthermore, the limiting member is arc-shaped, and both ends of the limiting member are respectively fixed in the main body.

[0016] Furthermore, the electric heating device is a PTC heating sheet.

[0017] The beneficial effect of the utility model is that: since the electric heating device is arranged in the drying arm, and the electric heating device corresponds to the air outlet on the drying arm, the air at the electric heating device is already in a heated state, and the wind blown by the fan blows to the electric heating device through the air duct to naturally blow out the hot air, and basically no heat loss is generated, so the hot air can be better delivered, and based on this, the electric heater device does not need to use a PTC heating component with a corrugated heat sink, only an ordinary electric heating device (such as a PTC heating sheet, etc.) needs to be selected, which can reduce costs.
