Liquid conveying device and air conditioning equipment

Abstract

The utility model relates to the technical field of air conditioning equipment, in particular to a liquid conveying device and air conditioning equipment. In the liquid conveying process of the liquid conveying device, the conveying assembly operates, and then the liquid is conveyed through the conveying assembly. The vibration is generated in the operation process of the conveying assembly, and the fixing assembly fixes the conveying assembly in a clamping mode, so that the degree of freedom of the conveying assembly in the clamping force direction of the fixing assembly is limited, and the degree of freedom of the conveying assembly in the non-clamping force direction of the fixing assembly is not limited. Due to the fact that the rotating direction of the conveying assembly is not parallel to the direction of the clamping force of the fixing assembly on the conveying assembly, the conveying assembly can move within the vibration range of the conveying assembly, the influence of vibration generated by the conveying assembly on the fixing assembly is reduced, and the vibration of the fixing assembly is reduced. In this way, the risk that due to vibration of the conveying assembly, a structure related to the conveying assembly is loosened is reduced, and noise generated by vibration of the conveying assembly is reduced.

[0044] Please refer to Figures 1 to 2 In some embodiments of the present application, the present application provides an air conditioning device 10, comprising: a liquid tank assembly 20, a liquid droplet generating device 30 and a liquid conveying device 40. The liquid tank assembly 20 is used to contain liquid. The liquid droplet generating device 30 is used to generate liquid droplets. The liquid conveying device 40 is used to convey liquid from the liquid tank assembly 20 to the liquid droplet generating device 30, so that the liquid droplet generating device 30 can continuously generate liquid droplets.

[0045] It can be understood that in the air conditioning device 10, the liquid is contained by the liquid tank assembly 20, and the liquid in the liquid tank assembly 20 is atomized by the atomizing device, so as to achieve the effect of improving air freshness and adjusting air humidity. The liquid conveying device 40 conveys the liquid in the liquid tank assembly 20 to the liquid droplet generating device 30, so that the liquid droplet generating device 30 can continuously generate liquid droplets, and then generate the visual effect of liquid droplets under the cooperation of light.

[0046] Please refer to Figures 2 to 4 In some embodiments of the present application, the present application provides a liquid conveying device 40, comprising: a conveying assembly 41 and a fixing assembly 42. The conveying assembly 41 is used to convey liquid. The fixing assembly 42 fixes the conveying assembly 41 by clamping. The clamping force direction of the fixing assembly 42 on the conveying assembly 41 is not parallel to the vibration direction of the conveying assembly 41.

[0047] The conveying assembly 41 is fixed by the fixing assembly 42, and the fixing assembly 42 is installed on the air conditioning device 10, so that the conveying assembly 41 can stably convey the liquid. During the conveying of the liquid by the liquid conveying device 40, the conveying assembly 41 operates, and then the liquid is conveyed by the conveying assembly 41.

[0048] During the operation of the conveying assembly 41, vibration is generated, and the fixing assembly 42 fixes the conveying assembly 41 by clamping, so that the conveying assembly 41 is limited in the direction of the clamping force of the fixing assembly 42, and is not limited in the direction other than the clamping force.

[0049] By limiting the freedom of the conveying assembly 41 in the direction of the clamping force, the conveying assembly 41 can stably and reliably work. Since the rotating direction of the conveying assembly 41 is not parallel to the clamping force direction of the fixing assembly 42 on the conveying assembly 41, the conveying assembly 41 can move in the vibration range, thereby reducing the influence of the vibration of the conveying assembly 41 on the fixing assembly 42, and reducing the vibration of the fixing assembly 42. Further, the risk of loosening of the structure related to the vibration of the conveying assembly 41 is reduced, and the noise caused by the vibration of the conveying assembly 41 is reduced.

[0050] In this way, the vibration of the liquid conveying device 40 is reduced, and the influence of the vibration of the liquid conveying device 40 on the air conditioning device 10 is reduced.

[0051] In some embodiments of the present application, the clamping force direction of the fixing assembly 42 on the conveying assembly 41 is perpendicular to the vibration direction of the conveying assembly 41.

[0052] By making the clamping force direction of the fixing assembly 42 on the conveying assembly 41 perpendicular to the rotating direction of the conveying assembly 41, the conveying assembly 41 is given the maximum freedom in the vibration direction, and the influence of the vibration of the conveying assembly 41 on the fixing assembly 42 is minimized. Since the liquid conveying device 40 is connected to the outside through the fixing assembly 42, when the fixing assembly 42 is least affected by the vibration of the conveying device, the vibration of the liquid conveying device 40 is reduced on the one hand, and the influence of the vibration of the liquid conveying device 40 on the external device is reduced on the other hand.

[0053] In some embodiments of the present application, the delivery assembly 41 comprises an impeller 411, a driving motor 412, and a pump body 413. The impeller 411 provides kinetic energy for the flow of the liquid by rotation. The driving motor 412 is used to drive the impeller 411 to rotate. The pump body 413 is used to accommodate the impeller 411 and the driving motor 412, and the pump body 413 is provided with a liquid flow channel 414 for the flow of the liquid. The clamping force direction of the fixing assembly 42 on the delivery assembly 41 is parallel to the rotation center axis direction of the impeller 411.

[0054] During the operation of the delivery assembly 41, the driving motor 412 is driven to rotate, and the impeller 411 is driven to rotate, and then the centrifugal force generated by the rotation of the impeller 411 provides kinetic energy for the liquid, and then the liquid can continuously flow, and the delivery of the liquid is completed. During the rotation of the impeller 411 driven by the driving motor 412, vibration will be generated. The driving motor 412 drives the impeller 411 to rotate, that is, the centrifugal force is generated. Due to the inevitable errors in the production and assembly process, the centrifugal force at different rotation angle positions in the tangential direction of the rotation of the impeller 411 is not uniform, that is, the centrifugal force changes in different directions, thereby causing the delivery assembly 41 to generate vibration, and the vibration direction is perpendicular to the rotation center axis of the impeller 411.

[0055] By making the clamping force direction of the fixing assembly 42 on the delivery assembly 41 parallel to the rotation center axis direction of the impeller 411, the clamping force direction of the fixing assembly 42 on the delivery assembly 41 is perpendicular to the vibration direction of the delivery assembly 41, thereby reducing the influence of the vibration of the delivery assembly 41 on the clamping of the fixing assembly 42 on the delivery assembly 41, and reducing the vibration of the fixing assembly 42 caused by the vibration of the delivery assembly 41, thereby reducing the influence of the vibration of the delivery assembly 41 on the fixing assembly 42, reducing the vibration of the fixing assembly 42, and further reducing the overall vibration of the liquid delivery device 40, and reducing the influence of the vibration of the liquid delivery device 40 on external equipment.

[0056] In some embodiments of the present application, the rotation center axis of the impeller 411 is collinear with the rotation center axis of the driving motor 412.

[0057] By making the rotation center axis of the impeller 411 collinear with the rotation center axis of the driving motor 412, the eccentric force generated by the impeller 411 on the rotation shaft of the driving motor 412 is reduced, and the vibration generated by the delivery assembly 41 during operation is reduced.

[0058] In some embodiments of the present application, the guiding direction of the liquid flow channel 414 on the liquid is parallel to the clamping force direction of the fixing assembly 42 on the delivery assembly 41.

[0059] When the liquid enters the liquid flow channel 414, the kinetic energy carried by the liquid is mostly released in the direction in which the liquid flow channel 414 guides the liquid, so that the liquid can flow in the direction in which the liquid flow channel 414 guides the liquid; and a small part of the kinetic energy carried by the liquid is transmitted to the side wall of the liquid flow channel 414 due to the force of the liquid on the side wall of the liquid flow channel 414, thereby causing the pump body 413 to vibrate, and the vibration of the pump body 413 is most obvious in the direction perpendicular to the direction in which the liquid flow channel 414 guides the liquid.

[0060] By making the direction in which the liquid flow channel 414 guides the liquid parallel to the clamping force direction of the fixing assembly 42 on the conveying assembly 41, the clamping force direction of the fixing assembly 42 on the conveying assembly 41 is perpendicular to the vibration direction of the pump body 413, thereby reducing the influence of the vibration of the pump body 413 on the fixing assembly 42, and further reducing the vibration of the fixing assembly 42.

[0061] Please refer to Figures 2 to 4 In some embodiments of the present application, the pump body 413 is provided with a liquid suction cavity 415, and the impeller 411 is arranged in the liquid suction cavity 415, and the liquid flow channel 414 is in communication with the liquid suction cavity 415.

[0062] During rotation of the impeller 411, the impeller 411 causes the liquid to flow by centrifugal action, and the liquid flows from the liquid suction cavity 415 to the liquid flow channel 414. When the liquid flows out of the liquid suction cavity 415 under the action of the impeller 411, the pressure in the liquid suction cavity 415 decreases, so that the liquid in the liquid tank assembly 20 enters the liquid suction cavity 415 under the action of negative pressure. In this way, under the continuous rotation of the impeller 411, the liquid in the liquid suction cavity 415 continuously flows to the liquid flow channel 414, and the liquid in the liquid tank assembly 20 continuously enters the liquid suction cavity 415. In this way, the liquid is conveyed by the conveying assembly 41.

[0063] In some embodiments of the present application, the communication port of the liquid suction cavity 415 and the liquid flow channel 414 is located outside the edge of the rotation area of the impeller 411.

[0064] By arranging the communication port of the liquid suction cavity 415 and the liquid flow channel 414 outside the edge of the rotation area of the impeller 411, the liquid enters the liquid flow channel 414 after leaving the rotation area of the impeller 411, thereby reducing the kinetic energy loss of the liquid and improving the conveying efficiency of the liquid by the conveying assembly 41.

[0065] In some embodiments of the present application, the direction in which the liquid flow channel 414 guides the liquid flow is perpendicular to the tangent direction of the rotation area of the impeller 411.

[0066] By making the guiding direction of the liquid flow channel 414 to the liquid flow perpendicular to the tangent direction of the rotating area of the impeller 411, the interaction force between the liquid and the side wall of the liquid flow channel 414 after the liquid enters the liquid flow channel 414 is reduced, the kinetic energy of the liquid is transmitted to the side wall of the liquid flow channel 414 is reduced, on the one hand, the vibration of the pump body 413 is reduced, on the other hand, the kinetic energy loss of the liquid is reduced, and the conveying efficiency of the conveying assembly 41 to the liquid is improved.

[0067] In some embodiments of the present application, the fixing assembly 42 comprises a first fixing member 421 and a second fixing member 423. The first fixing member 421 is provided with a limiting part 422. The second fixing member 423 is provided with a containing cavity 424, the conveying assembly 41 is arranged in the containing cavity 424, and the second fixing member 423 is fixedly installed on the first fixing member 421. Wherein, after the second fixing member 423 is installed on the first fixing member 421, the limiting part 422 abuts the conveying assembly 41 in the containing cavity 424.

[0068] By clamping the conveying assembly 41 by the first fixing member 421 and the second fixing member 423, the influence of the vibration of the conveying assembly 41 on the fixing assembly 42 is reduced under the condition of reliably fixing the conveying assembly 41, and the vibration of the liquid conveying device 40 as a whole to the outside is reduced.

[0069] By arranging the conveying assembly 41 in the containing cavity 424 of the second fixing member 423, on the one hand, the conveying assembly 41 is protected by the second fixing member 423, and on the other hand, the vibration range of the conveying assembly 41 is limited by the side wall of the containing cavity 424 to ensure that the conveying assembly 41 can work normally.
