Description

Technical Field

[0001] The utility model relates to the technical field of fan structures of air coolers, in particular to a fan structure of an air cooler. Background Art

[0002] The working cycle of the air cooler generally consists of the following main components:

[0003] 1. Compressor: The compressor in the air cooler is the core of the entire system. It compresses the refrigerant into high-temperature and high-pressure gas.

[0004] 2. Air cooler: The evaporator is located inside the air cooler and converts the refrigerant from high-temperature and high-pressure gas to low-temperature and low-pressure gas through contact with the refrigerant.

[0005] 3. Condenser: The condenser is responsible for converting the refrigerant from a low-temperature, low-pressure gas to a high-temperature, high-pressure gas, and discharges it through the exhaust system of the air cooler.

[0006] 4. Fan: The fan forces air to flow, blowing the hot air in the room into the condenser for cooling.

[0007] However, current air cooler fan structures are mostly installed on the condenser by bolts. Although the bolts can ensure its stability, the vibration caused by the operation of the fan can easily cause the bolts fixing the fan to loosen, thereby increasing the noise of the air cooler during operation and easily causing damage to the fan. For this reason, the present application proposes a fan structure for an air cooler that can be stably and quickly installed without the aid of tools. Utility Model Content

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-Figure 4 As shown, the embodiment of the utility model proposes a fan structure of a cooling fan, including:

[0026] Refrigerator 1, Refrigerator 1 includes a compressor and a condenser, which is prior art and will not be described again;

[0027] The fan assembly is mounted on the refrigerator 1; the fan assembly includes three protective nets 2, the protective nets 2 are composed of multiple annular stainless steel rings, and four belt-shaped support legs 3 are welded on the protective nets 2. The shape of the support legs 3 is as follows Figure 2 , Figure 4 As shown, it is similar to a belt placed flat in a long ring shape; a mounting block 4 is installed in the middle of the protection net 2, and the mounting block 4 is located in the middle of the protection net 2. When the protection net 2 abuts against the refrigerator 1, the fixed foot 10 also abuts against the refrigerator 1 at this time;

[0028] A fan 11 is mounted on the mounting block 4, and a fixed foot 10 is provided at the other end of the supporting foot 3, and the fixed foot 10 is integrally formed with the supporting foot 3; four limiting covers 9 are fixed on the refrigerator 1, and the fixed foot 10 is located in the limiting cover 9 and locked by a positioning mechanism, and the positioning mechanism includes a positioning pin 7 that penetrates the fixed foot 10 to position it;

[0029] Explanation of the locating pin 7 part:

[0030] The limiting cover 9 includes an L-shaped block fixed on the refrigerator 1, and one end of the L-shaped block away from the fan 11 is blocked by the limiting block. When the fixed foot 10 is located in the limiting cover 9, the fixed foot 10 is against the limiting block and the L-shaped block. In this way, the fixed foot 10 can be supported and limited by the four limiting covers 9 to prevent it from shaking. The positioning pin 7 passes through the limiting cover 9 and is slidably connected thereto. The outer wall of the refrigerator 1 is provided with a card slot 6, and the positioning pin 7 passes through the fixed foot 10 and is slidably connected in the card slot 6. When the positioning pin 7 passes through the fixed foot 10 and is located in the card slot 6, the fixed foot 10 can be locked, and the stability of the fan structure installation can be ensured;

[0031] Since the pull block 5 is fixedly connected to the positioning pin 7, a spring 8 is installed between the pull block 5 and the limit cover 9, the positioning pin 7 and the card slot 6 are tightly pressed against each other under the action of the spring 8, so that the fixed foot 10 can be stably locked;

[0032] When installing the fan structure, the staff will make the fixed foot 10 against the refrigerator 1, so that the four fixed feet 10 are located in the four limit covers 9 and against the positioning pin 7, and then the staff will cooperate with each other to manually pull the pull block 5 to drive the positioning pin 7 to move, so that it is out of the slot 6 and the fixed foot 10 can be rotated into the limit cover 9 until it cannot move, and then release the pull block 5. Under the action of the spring 8, the pull block 5 and the positioning pin 7 are reset, and the positioning pin 7 passes through the fixed foot 10 and is located in the slot 6, completing the installation of the fan structure. It is simple and quick, does not require the help of tools, and is not easy to loosen due to the vibration of the fan 11;

[0033] Among them, an annular rod can be welded on the four pulling blocks 5, and pulling the annular rod can drive the four pulling blocks 5 to move, and a single staff member can operate it, which is more convenient.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
