[0001] The invention relates to the technical field of air conditioning equipment, and in particular to a wet curtain missing installation protection structure and a cooling fan. Background Art

[0002] Nowadays, common cooling fans use wet curtains to achieve the purpose of blowing out cold air by utilizing the principle of water evaporation and heat absorption. At the same time, installing wet curtains can also prevent water from falling directly from the water distribution box and splashing onto electrical components or being sucked into the fan when falling. However, existing cooling fans can still start the fan without installing wet curtains, which poses an electrical safety hazard. Summary of the invention

[0003] The first purpose of the present invention is to provide a wet curtain missing protection structure to solve the electrical safety problem caused by the existing cold fan being able to start without installing a wet curtain.

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] Combined with Figure 1-4As shown, this embodiment provides a wet curtain missing installation protection structure, a water receiving structure 1, a mounting plate 6, a housing 2 and a stop mechanism 4. The mounting plate 6 of this embodiment can be the rear housing of the cooling fan; further, the housing 2 of this embodiment can be the outer shell of the water receiving structure 1 or the rear net bracket, the housing 2 is detachably connected to the water receiving structure 1, or the housing 2 is detachably connected to the water receiving structure 1 and the mounting plate 6 respectively, the wet curtain 5 is installed on the water receiving structure, and is located between the mounting plate 6 and the housing 2, so it can be said that an installation position 11 for installing the wet curtain 5 is provided between the mounting plate 6 and the housing 2, and the installation position 11 is in the water receiving structure 1. When the cooling fan is running, the wet curtain 5 is installed at the installation position 11.

[0035] Based on the problems in the background technology, the present embodiment arranges the switch mechanism 3 on the mounting plate 6, and the switch mechanism 3 is used to open and close the operating circuit of the cooling fan; the shell 2 of the present embodiment is provided with a triggering part 21 that can trigger the switch mechanism 3, and after the shell 2 is assembled with the water receiving structure 1 and the mounting plate 6, the shell 2 realizes the normal opening of the switch mechanism 3, thereby ensuring the operation of the cooling fan.

[0036] Preferably, in order to improve the safety protection effect, the switch mechanism 3 of this embodiment includes a double-pole switch to improve the safety of the cooling fan during use.

[0037] Combined with Figure 1-5 As shown, in this embodiment, a stop mechanism 4 is newly provided on the mounting plate 6, and the stop mechanism 4 moves between the first state and the second state under the action of the wet curtain 5 and its own restoring force.

[0038] Combined with Figure 1 As shown, when the wet curtain 5 of this embodiment is located at the installation position 11, the wet curtain 5 makes the stop mechanism 4 be in the first state, and the trigger part 21 can be connected to the switch mechanism 3. Specifically, the trigger part 21 can move toward the switch mechanism 3 (when the housing 2 is installed), and then the two are finally connected so that the trigger part 21 triggers the switch mechanism 3.

[0039] Combined with Figure 2-4 As shown, when the wet curtain 5 of this embodiment is detached from the installation position 11 and the mounting plate 6 is disconnected from the shell 2, the stopping mechanism 4 is in the second state and blocks the connection between the shell 2 and the water receiving structure 1, preventing the triggering part 21 from triggering the switch mechanism 3, specifically blocking the path of the bottom of the shell 2 moving toward the top of the water receiving structure 1, preventing the two from being connected.

[0040] If the above structure needs to remove the wet curtain 5, the shell 2 must be removed first. When installing the shell 2, if the wet curtain 5 located between the shell 2 and the mounting plate 6 is not installed first, the stop mechanism 4 will limit the connection between the shell 2 and the water receiving structure 1, thereby preventing the triggering part 21 of the shell 2 from triggering the switch mechanism 3, reminding the operator to install the wet curtain 5 to the mounting position 11 first, and then install the shell 2, to prevent electrical safety hazards caused by the cold fan being able to be started without the wet curtain 5 installed.

[0041] Furthermore, the switch mechanism 3 of this embodiment includes a mounting groove (not shown in the figure) and a switch button located in the mounting groove. The mounting groove is arranged on the mounting plate 6, and an opening is provided at the top of the mounting groove. The trigger part 21 triggers the switch button through the opening at the top of the mounting groove.

[0042] Correspondingly, in order to ensure the coordination between the trigger part 21 and the switch mechanism 3, the trigger part 21 of this embodiment includes a protrusion that is adapted to the shape and size of the mounting groove. After the shell 2, the water receiving structure 1 and the mounting plate 6 are assembled, the protrusion is located in the mounting groove and triggers the switch mechanism 3.

[0043] Furthermore, the stop mechanism 4 of this embodiment may be Figure 1 and 5 As shown in the figure, the stop mechanism 4 includes a baffle 41 and an elastic member 42; the baffle 41 is hinged on the side wall of the water receiving structure 1, specifically, a rotating shaft 43 is provided on the baffle 41, and an axial hole 12 matched with the rotating shaft 43 is provided on the side wall of the water receiving structure 1, and the rotating shaft 43 is connected to the water receiving structure 1 so that the baffle 41 can rotate on the side wall of the water receiving structure 1; the baffle 41 of this embodiment is provided with a stop portion 411; the elastic member 42 of this embodiment is connected to the baffle 41 to realize the resetting of the baffle 41 from the first state to the second state, specifically, the elastic member 42 of this embodiment can be a torsion spring sleeved on the rotating shaft 43, and the two ends of the torsion spring are respectively connected to the baffle 41 and the water receiving structure 1.

[0044] When the wet curtain 5 of this embodiment is located at the installation position 11, the limit baffle 41 rotates to the first state, that is, Figure 1 In the state of middle, the elastic member 42 contracts and accumulates elastic potential energy.

[0045] When the wet curtain 5 of this embodiment is detached from the installation position 11 and the shell 2 is disconnected from the water receiving structure 1, the baffle 41 rotates to the second state under the action of the elastic potential energy of the elastic member 42. At this time, the stopper 411 is located on the path of the shell 2 moving toward the water receiving structure 1 to prevent the connection between the shell 2 and the water receiving structure 1, thereby preventing the triggering part 21 of the shell 2 from triggering the switch mechanism 3.

[0046] Specifically, when the baffle 41 of this embodiment rotates to the second state, the stopper 411 is located at the top of the water receiving structure 1, just separating the top of the water receiving structure 1 and the shell 2, effectively preventing the two from being connected.

[0047] The stopper 411 of this embodiment is a blocking piece that is arranged at the top and extends outwards; the blocking piece is located at a side away from the hinged connection between the baffle plate 41 and the water receiving structure 1 .

[0048] Preferably, in order to prevent the stopping mechanism 4 from occupying the space of the installation position 11 in the water receiving structure 1, the side wall of the water receiving structure 1 of this embodiment is provided with a receiving groove; when the stopping mechanism 4 is in the first state, the baffle 41 is located in the receiving groove.

[0049] The stop mechanism 4 of the above structure is obviously superior to the existing structure combining sensors and control devices. There is no need to consider the circuit routing and the problem of moisture or water ingress to the sensor and control device. The leakage-proof installation of the wet curtain 5 is achieved through a simple mechanical structure.

[0050] In addition, based on the above structure, this embodiment further provides a cooling fan, which includes the wet curtain missing protection structure described in the above technical solution. Since the improvement of the cooling fan of this embodiment is only the wet curtain missing protection structure, and other structures are not improved, this embodiment does not describe other structures of the cooling fan and illustrate them with drawings, but those skilled in the art can fully understand its structure.
