[0037] Embodiment 1:

[0038] Please refer to Figure 1 -6. This embodiment provides a mounting shell and a cold fan. The mounting shell 100 can block the water leakage hole 113 when the wet curtain 200 is not installed, thereby preventing water from flowing to the fan motor, solving the problem of water splashing and noise of the fan, and ensuring the normal use of the fan blowing function. When the wet curtain 200 is installed, the water leakage hole 113 is opened by the water control component 120 to ensure the normal use of the cooling function of the cold fan.

[0039] The mounting shell 100 includes a housing 110 and a water control assembly 120 and a sensor 130 respectively mounted on the housing 110. The housing 110 is provided with an assembly area 112 for mounting the wet curtain 200 and a water tank 111 located above the assembly area 112. The housing 110 is provided with a water leakage hole 113 for connecting the water tank 111 and the assembly area 112. The water control assembly 120 includes a driving member 121, a piston 122, a transmission mechanism 123 and a piston sleeve 124. The transmission mechanism 123 includes a connecting rod 123'1, a roller 123'2 and a bracket 123'3. The connecting rod 123'1 is provided with a first slide groove 123'4 for connecting with the roller 123'2 and a second slide groove 123'5 for connecting with the piston 122. The peripheral side of the piston sleeve 124 is provided with a notch 124'1. The water tank 111 is divided into a water storage section 111'1 and an overflow section 111'2. An overflow plate 111'3 is arranged between the water storage section 111'1 and the overflow section 111'2. The height of the overflow plate 111'3 is lower than the height of the water tank 111, so that the water in the water storage section 111'1 can flow to the overflow section 111'2. The overflow section 111'2 is provided with an overflow hole 111'4, and the leakage hole 113 is located in the water storage section 111'1.

[0040] refer to Figure 2 and Figure 3 As shown, the water tank 111 is arranged on the upper part of the housing 110, and the sensor 130 is arranged on the side of the housing 110. The water tank 111 is L-shaped, the water leakage hole 113 is located in the water storage section 111'1, the overflow hole 111'4 is located in the overflow section 111'2, and the water control component 120 is partially located outside the water tank 111. The water control component 120 is used to control the opening and closing of the water leakage hole 113. The sensor 130 is used to detect the wet curtain 200. The sensor 130 can be a light sensor 130 or a proximity sensor 130. When the sensor 130 detects the wet curtain 200, the sensor 130 sends an electrical signal to the main control board, and the main control board controls the water control component 120 to work. The water control component 120 makes the water leakage hole 113 in an open state, and the water in the water storage section 111'1 flows from the water leakage hole 113 to the wet curtain 200 assembly area 112, and then flows into the wet curtain 200, ensuring the normal use of the cooling function of the cold fan. When the sensor 130 detects that the wet curtain 200 is not installed, the sensor 130 sends an electrical signal to the main control board indicating that the wet curtain 200 is not installed. The main control board controls the water control component 120 to work, and the water control component 120 blocks the water leakage hole 113, so that the water cannot flow out of the water leakage hole 113, preventing the water from flowing to the fan blower, solving the problem of fan splashing and noise, and ensuring the normal use of the fan blowing function. After the water level in the water tank 111 rises and is higher than the overflow plate 111'3, the water flows to the overflow section 111'2, and then flows out of the housing 110 from the overflow hole 111'4 to prevent the water level from being too high.

[0041] Figure 4 It is a schematic diagram of a three-dimensional structure in which a water tank 111 and a water control component 120 are connected. Figure 5 It is a schematic diagram of the blocked state of the water leakage hole 113; the driving member 121 is a driving motor, and the housing 110 is provided with a support seat for fixing the driving member 121. The driving member 121 is connected to the roller 123'2. The driving member 121 drives the roller 123'2 to rotate when it works. The axis of the roller 123'2 coincides with the rotation axis. The first slide groove 123'4 and the second slide groove 123'5 are respectively located at the opposite ends of the connecting rod 123'1. The first slide groove 123'4 is slidingly connected to the roller 123'2, and the connecting rod 123'1 is eccentrically installed on the roller 123'2. When the roller 123'2 rotates, it can drive the end of the connecting rod 123'1 connected to the roller 123'2 to move up and down. One end of the connecting rod 123'1 is located above the water tank 111, and the connecting rod 123'1 is slidably connected to the piston 122 through the second sliding groove 123'5. The bracket 123'3 is arranged between the piston 122 and the driving member 121, and the connecting rod 123'1 and the bracket 123'3 are rotatably matched. The connecting rod 123'1 and the bracket 123'3 form a lever mechanism. According to the lever principle, when the driving member 121 drives one side of the connecting rod 123'1 to move up and down, the other side of the connecting rod 123'1 moves in the opposite direction, that is, by controlling the driving member 121 to drive the connecting rod 123'1 to move, the connecting rod 123'1 drives the piston 122 to move toward the water leakage hole 113 or away from the water leakage hole 113. In order to ensure the stability of the movement of the piston 122, a piston sleeve 124 that can slidably cooperate with the piston 122 is provided at the end of the water leakage hole 113. The piston 122 moves back and forth in the piston sleeve 124. A recess 124'1 is provided on the circumferential side of the piston sleeve 124. When the connecting rod 123'1 drives the piston 122 to extend from the water leakage hole 113, water can flow into the water leakage hole 113 from the gap between the piston 122 and the recess 124'1, thereby ensuring the circulation of water.

[0042] Figure 6 This is a schematic diagram of the open state of the water leakage hole 113. The connection point between the roller 123'2 and the connecting rod 123'1 is located below the center of the roller 123'2. The height of the end of the connecting rod 123'1 connected to the piston 122 is greater than the height of the end of the connecting rod 123'1 connected to the roller 123'2. The connecting rod 123'1 drives the piston 122 away from the water leakage hole 113. The water leakage hole 113 is in the open state. The water in the water outlet trough 111 enters the water leakage hole 113 from the recess 124'1 of the piston sleeve 124 to ensure the circulation of water.

[0043] This embodiment further provides a cooling fan, comprising the above-mentioned mounting shell 100 .

[0044] In this practical solution, the roller 123'2 can be an eccentric wheel, and the main control board can adopt the control circuit board of the cold fan. The water control component 120 is installed on the shell 110. The water control component 120 can control the opening and closing of the water leakage hole 113. When the wet curtain 200 is not installed, the water control component 120 blocks the water leakage hole 113 to prevent water from flowing to the fan motor blower, solve the problem of fan splashing and noise, and ensure the normal use of the fan blowing function. When the wet curtain 200 is installed, the water control component 120 opens the water leakage hole 113 to ensure the normal use of the cooling function of the cold fan. The water control assembly 120 includes a piston 122 for blocking the water leakage hole 113, a connecting rod 123'1 mechanism that enables the piston 122 to reciprocate, and a driving member 121 that provides power for the reciprocating movement of the piston 122. The driving member 121 is eccentrically connected to the connecting rod 123'1, thereby driving one end of the connecting rod 123'1 to reciprocate up and down, that is, using the lever principle, the piston 122 is driven to reciprocate to achieve the opening and closing of the water leakage hole 113. By installing a sensor 130 on the housing 110, the automatic control of the opening and closing of the water leakage hole 113 is achieved.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
