Description

Technical Field

[0001] This utility model relates to the field of water-cooled fan technology, and more specifically to a water shortage alarm structure for water-cooled fans. Background Technology

[0002] Currently, the existing water-cooled fans on the market use an electronic level switch near the water pump in the water tank to achieve the effect of alarming when water is low.

[0003] A conventional electronic level switch consists of a magnetic ring float, a reed switch or Hall effect switch circuit board, and a sealing ring. It detects the water level using a built-in reed switch or Hall effect switch. When the tank contains water, the float rises to its highest point, and the switch is in the ON state. When the tank is low on water, the float drops, and the switch is in the OFF state, thus achieving water level detection.

[0004] However, this type of level switch is expensive because it needs to be immersed in water for a long time, requiring a waterproof structure. Also, prolonged immersion in water can cause the switch to malfunction and pose a risk of electrical leakage.

[0005] Therefore, there is an urgent need to provide a water shortage alarm structure that is simple in structure, low in cost, and long in life. Utility Model Content

[0006] In view of this, the present invention provides a water shortage alarm structure for a water-cooled fan.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a water shortage alarm structure for a water-cooled fan. The water-cooled fan is equipped with a water tank, a water trough, and a water pump. A pipe is provided between the water tank and the water trough, and water from the water tank flows to the water trough through the pipe. The water shortage alarm structure includes a bracket and a micro switch. Both the bracket and the micro switch are mounted on the water-cooled fan. The bracket has a first end, a second end, and a support portion located between the first end and the second end. The first end is located in the water trough of the water-cooled fan and corresponds to the water outlet of the pipe. The second end of the bracket corresponds to the actuating spring of the micro switch.

[0008] The first end is pushed down by the water flowing out of the outlet, causing the second end to tilt up, thereby pushing the actuating spring and closing the micro switch.

[0009] In a preferred embodiment of this utility model, the first end has a funnel-shaped chamber, and a through hole is formed at the bottom of the chamber;

[0010] Water flowing out of the outlet falls into the chamber and flows into the water tank through the through hole.

[0011] In a preferred embodiment of this utility model, the bracket is assembled on the water tank shell; the water tank shell forms the water tank; one of the supporting parts of the water tank shell and the bracket is provided with a shaft, and the other is provided with a locking hole; the water tank shell and the supporting part are assembled by the cooperation of the shaft and the locking hole, and the bracket tilts with the shaft as the fulcrum.

[0012] In a preferred embodiment of this utility model, the support part is U-shaped and has the shaft hole; the shaft is provided on one side wall of the water tank shell.

[0013] In a preferred embodiment of this utility model, the first end is located inside the water tank, and the second end is located outside the water tank.

[0014] In a preferred embodiment of this utility model, a slot is provided at the second end, and the actuating spring is inserted into the slot.

[0015] In a preferred embodiment of this invention, the micro switch is installed on the outer casing of the water-cooled fan.

[0016] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0017] 1. The water shortage alarm structure of this utility model has a simple structure and is easy to install by using a gravity rocker structure.

[0018] 2. The water shortage alarm structure of this utility model does not need to be immersed in water, and there is no need to consider waterproofing or leakage issues. It has a longer lifespan than existing liquid level switches.

[0019] 3. The water shortage alarm structure of this utility model has a low cost, only about 1 / 5 of the cost of a liquid level switch, which can effectively save the development cost of water-cooled fans.

[0020] 4. This utility model uses a micro switch to turn the water-cooled fan off and on, and then sends a signal to the MCU of the water-cooled fan to notify the user whether the water is low.

[0021] The working principle of the micro switch is based on mechanical force. The second end acts on the actuating spring. When the actuating spring moves to the critical point, it generates an instantaneous action, causing the moving contact to quickly connect or disconnect with the fixed contact, thus turning the micro switch off or on. 5. When the water tank of this utility model is short of water, the impact force disappears and the gravity of the water in the chamber disappears. The gravity of the second end, together with the actuating spring, generates a reverse action force, causing the second end to move downward, thus turning off the micro switch. It can accurately determine whether the water tank is short of water. The micro switch has a small contact spacing, which is suitable for precision control. When in use, the stroke required to complete the switching action is short, the response speed is fast, and the contact switching speed is fast, making it suitable for high-frequency switching scenarios.

[0037] For the water shortage alarm structure of the water-cooled fan, please refer to [link / reference]. Figure 1-9 As shown, the water-cooled fan 00 includes: a housing 340, a fan assembly, a water curtain assembly 350, a water tank 310, and a water pump 330 disposed inside the housing 340. A water tank housing 320 is disposed above the water curtain assembly 350, and the water tank housing 320 forms a water tank 321. The water tank 321 and the water tank 310 are connected by a pipe 01. When the water-cooled fan 00 is running, the water pump 330 draws water from the water tank 310 to the water tank 321 through the pipe 01, and the water in the water tank 321 drips onto the water curtain assembly 350. The fan assembly pushes the airflow through the water curtain assembly 350 and blows it out of the water-cooled fan 00, improving the user's cooling sensation.

[0038] The wind turbine components described above utilize existing technology, and their specific structure and principles will not be detailed here.

[0039] The water shortage alarm structure includes a bracket 100 and a micro switch 200, both of which are mounted on the water-cooled fan 00.

[0040] Specifically, such as Figure 2-3 and Figure 8-9 As shown, the bracket 100 has a first end 110, a second end 120, and a support portion 130 located between the first end 110 and the second end 120; the bracket 100 is assembled to the water-cooled fan 00 via the support portion 130.

[0041] After the bracket 100 is installed on the water-cooled fan 00, under external force, the second end 120 can be raised when the first end 110 moves down; and the first end 110 can be raised when the second end 120 moves down.

[0042] The first end 110, the second end 120, and the support part 130 can be either separate or integrated. In the case of a separate structure, they can be assembled by means of screws, clips, etc. In the case of an integrated structure, the first end 110, the second end 120, and the support part 130 can be made of plastic and are injection molded as a whole, reducing assembly steps.

[0043] After bracket 100 is installed on water cooling fan 00, as follows: Figure 3 As shown, the first end 110 is located in the water tank 321 of the water-cooled fan 00 and corresponds to the water outlet of the pipe 01; the second end 120 of the bracket 100 corresponds to the actuating spring 210 of the micro switch 200.

[0044] The water shortage alarm structure of this water-cooled fan is mainly used to detect whether there is a water shortage in the water tank 310.

[0045] When the water tank 310 is full and the water-cooled fan 00 is running, the water pump 330 runs, transporting the water in the water tank 310 to the water tank 321 through the pipe 01. During the water transport process, the water flows out from the outlet and flows downward under gravity, impacting the first end 110. The first end 110 is pushed down by the water flowing out from the outlet, causing the second end 120 to tilt up, thereby pushing the action spring 210 to close the micro switch 200. When the micro switch 200 is in the closed state, it sends a signal to the MCU of the water-cooled fan 00. After receiving the feedback signal, the MCU confirms that there is water and the water pump 330 continues to work.

[0046] When the water tank 310 is dry, the water pump 330 will "dry pump" if it continues to run, which can easily burn out the water pump 330. When the water pump 330 is dry pumping, no water flows out of the outlet, and the water flow impact force acting on the first end 110 disappears. Then, the second end 120 moves downward under its own weight and the action spring 210, and the first end 110 tilts up, which opens the micro switch 200. When the micro switch 200 is in the open state, it sends a signal to the MCU of the water cooling fan 00. After receiving the feedback signal, the MCU confirms that the water is in a water shortage state, and the water pump 330 stops working.

[0047] The above methods can be used to determine whether the water tank 310 is short of water, thus preventing the water pump 330 from continuously pumping dry.

[0048] The circuit board of the water-cooled fan 00 can be equipped with an alarm module, which can notify the user that the water tank 310 is low on water through at least one of the following methods: light, sound, vibration, etc., and remind the user to add water in time.

[0049] In one embodiment, the first end 110 has a funnel-shaped chamber 111, and a through hole 112 is formed at the bottom of the chamber 111; water flowing out of the outlet falls into the chamber 111 and flows into the water tank 321 through the through hole 112.

[0050] After the chamber 111 is set up, the water flowing out of the outlet can be partially accumulated in the chamber 111, increasing the weight of the first end 110, ensuring that the first end 110 moves down while the second end 120 tilts up to trigger the micro switch 200.

[0051] The funnel shape of chamber 111 is designed to better collect the water flowing out of the outlet.

[0052] Furthermore, water in the water tank 321 flows out to the water curtain paper assembly 350, wetting the water curtain assembly 350.

[0053] In one implementation, such as Figure 3-7 As shown, the bracket 100 is assembled in the water tank housing 320. The water tank housing 320 and the support part 130 of the bracket 100 are provided with a shaft and a locking hole respectively. The water tank housing 320 and the support part 130 are assembled by the shaft and the locking hole. The bracket 100 tilts with the shaft as the fulcrum.

[0054] Specifically, such as Figure 9 As shown, the support part 130 is U-shaped and has a shaft hole 131. A notch 323 is provided on one side wall of the water tank housing 320. A shaft 322 is provided in the notch 323. After installation, the shaft 322 is inserted into the shaft hole 131, so that the bracket 100 can be tilted around the shaft 322 as a fulcrum. The support part 130 passes through the notch 323. The first end 110 is located inside the water tank 321, which can ensure that water flows to the water tank 321. The second end 120 is located outside the water tank 321. The micro switch 200 is also located outside the water tank 321 to prevent the micro switch 200 from being splashed wet.

[0055] In one embodiment, the second end 120 is provided with a slot, and the actuating spring 210 is inserted into the slot to ensure that the second end 120 and the actuating spring 210 are linked. When the second end 120 moves up and down, the actuating spring 210 moves accordingly, controlling the micro switch 200 to close or open.

[0056] Furthermore, such as Figure 6 As shown, the micro switch 200 is installed at the housing 340 of the water-cooled fan 00.

[0057] like Figure 5As shown, the water tank 310 and the water trough 321 are connected by a pipe 01. The pipe 01 includes a soft rubber tube 012 and a hard plastic tube 011 disposed on the outer casing 340. One end of the soft rubber tube 012 extends into the water tank 310, and the other end is inserted into the hard plastic tube 011. The hard plastic tube 011 forms the water outlet.

[0058] Continue as Figure 4 As shown, the water pump 330 is installed outside the water tank 310. The water pump 330 is connected to the water tank 310, the water pump 330 and the water tank 321 through the pipe 01. The main function is to provide power to drive the water to flow from the water tank 310 to the water tank 321 at a higher position.

[0059] like Figure 8 As shown, under the premise of horizontal installation, the position of the first end 110 of the support part 130 is lower than the position of the second end 120, and the volume of the first end 110 is greater than the volume of the second end 120.

[0060] 100 brackets Figure 3 As shown, after being installed on the water tank housing 320, the position of the bracket 100 is as follows when there is no water flow: Figure 8 As shown; when water flow is applied, the first end 110 moves downward and the second end 120 moves upward, that is, the bracket 100 rotates counterclockwise by a certain displacement around the shaft hole 131, causing the actuating spring 210 to move upward and the micro switch 200 to close; after the water flow disappears, the position of the bracket 100 returns to its original position. Figure 8 As shown, micro switch 200 is off.

[0061] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
