Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically a two-season fan with heating and purification functions. Background Technology

[0002] As consumers demand higher quality home environments, two-season fans, which combine cooling and heating functions, are gradually being widely used in homes, offices, and other settings.

[0003] However, traditional dual-season fans still have significant shortcomings in terms of functional integration and thermal efficiency. Most traditional dual-season fans achieve cooling and heating switching through simple function stacking, such as providing warm air solely through a PTC heating module. Traditional dual-season fans generally use PTC (positive temperature coefficient thermistor) as the heating element. Although PTC has advantages such as automatic temperature limiting and high safety, its thermal efficiency has inherent limitations.

[0004] Poor heat transfer efficiency: There is a gap between the PTC element and the metal heat sink, which needs to be filled with thermal grease. However, long-term high temperature will cause the grease to harden, increase thermal resistance, and reduce thermal efficiency year by year.

[0005] High temperature sensitivity: The heating power of PTC is closely related to the heat dissipation conditions. When the ambient temperature or wind speed fluctuates, the output temperature is not stable enough, which affects the heating effect.

[0006] To address this issue, those skilled in the art have proposed a two-season fan with heating and purification functions to solve the problems raised in the background art. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a two-season fan with heating and purification functions. It uses a high-efficiency heating wire instead of PTC and integrates purification, circulation and oscillation functions into a compact structure, which occupies less space.

[0008] A two-season fan with heating and purification functions includes a bottom support plate, a support rod installed on the top of the bottom support plate, and a fan body rotatably connected to the top of the support rod.

[0009] The fan body has a filter mechanism and a heating mechanism on its inner side. The filter mechanism includes an air inlet, which is installed on the inner side of one end of the fan body. The other end of the fan body has an air outlet. The middle part of the fan body also has fan blades for generating wind.

[0010] Preferably, the heating mechanism is also located inside the fan body. The heating mechanism includes a heating wire, which is located inside the fan body and is limited by arc-shaped plates at both ends.

[0011] Preferably, the heating wire is arc-shaped and fits tightly against the arc plate on the inner side of the fan body.

[0012] Preferably, the arc-shaped plate on the outside of the heating wire is a heat insulation plate.

[0013] Preferably, the bottom of the fan body is provided with a connecting shaft, and the top of the support rod is also equipped with a rotating head, which is rotatably connected to the connecting shaft.

[0014] Preferably, a drive motor is also installed inside the fan body, and a gear is provided on the outside of the drive motor. A connecting gear is meshed on the outside of the gear, and the drive motor and the connecting gear drive the fan body to swing up and down.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This fan uses iron-chromium-aluminum alloy heating technology, eliminating the problem of declining thermal efficiency year by year. It maintains stable heating efficiency throughout the entire product's lifespan. The stability of the heating element reduces the risk of equipment failure and damage due to performance degradation of the heating element, thus extending the overall lifespan of the fan. This not only saves users the cost of replacing equipment but also reduces the generation of electronic waste. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] As attached Figure 1 To be continued Figure 6 As shown:

[0026] Example 1: According to Figures 1-6 As shown, this utility model provides a two-season fan with heating and purification functions, including a bottom support plate 1, a support rod 2 installed on the top of the bottom support plate 1, and a fan body 3 rotatably connected to the top of the support rod 2.

[0027] The base used for the bottom support plate 1 is an iron base;

[0028] The fan body 3 has a filter mechanism and a heating mechanism on its inner side. The filter mechanism includes an air inlet 5, which is installed on the inner side of one end of the fan body 3. An air outlet 4 is installed on the other end of the fan body 3. A fan blade 6 is also provided in the middle of the fan body 3 to generate airflow. The heating mechanism is also located on the inner side of the fan body 3. The heating mechanism includes a heating wire 7, which is located on the inner side of the fan body 3 and is limited by arc-shaped plates at both ends. The arc-shaped heating wire 7 fits tightly against the arc-shaped plates on the inner side of the fan body 3. The arc-shaped plate on the outer side of the heating wire 7 is a heat insulation plate. A connecting shaft 8 is provided at the bottom of the fan body 3. A rotating head 9 is also installed at the top of the support rod 2. The rotating head 9 is connected to the connecting shaft. The components 8 are rotatably connected together. A drive motor 11 is also installed inside the fan body 3. A gear is provided on the outside of the drive motor 11, and a connecting gear 10 is meshed on the outside of the gear. The drive motor 11 and the connecting gear 10 drive and adjust the up and down swing of the fan body 3. This fan adopts iron-chromium-aluminum alloy heating technology, which does not have the problem of decreasing thermal efficiency year by year. It can maintain a stable heating efficiency throughout the entire product life. Due to the stability of the heating wire, the risk of equipment failure and damage caused by the performance degradation of the heating element is reduced. The rotating head 9 is connected to the motor set in the support rod 2. The motor drives the rotating head 9 to swing left and right. A motor is also set inside the fan body 3. The up and down swing effect can be produced by the internal motor drive.

[0029] Working principle: When this device is needed, the motor built into the fan body 3 near the fan blades 6 drives the fan blades 6 to work, allowing the fan blades 6 to draw in outside air through the air inlet 5. The outside air is filtered through the air inlet 5 and enters the fan blades 6, and then is discharged from the air outlet 4 through the heating wire 7. If heating is required, the heating wire 7 is turned on to heat the passing air, so that the air blown out is hot air. In use, the motor drives the rotating head 9 to rotate, so that the connecting shaft 8 can adjust the angle of the fan body 3 to achieve the angle adjustment function.
