Liquid drop drainage device and air conditioning equipment

Abstract

The utility model relates to the technical field of air conditioning equipment, in particular to a liquid drop drainage device and air conditioning equipment. When the liquid drops drop to the liquid drop drainage device, the liquid drops enter the liquid guide channel and then make contact with the tip of the drainage piece. When the liquid drop contacts the tip of the drainage piece, the surface of the liquid drop is punctured by the tip, so that the surface tension of the liquid drop is broken, the liquid drop is attached to the outer wall of the drainage piece and flows to the drainage main body from the tip, and the liquid drop is prevented from splashing. In the process that the liquid drops flow in the mode of being attached to the outer wall of the drainage piece, the outer portions of the liquid drops are restrained through the inner wall of the liquid guide channel, and therefore the situation that the outward diffusion range of the liquid drops is too large under the counter-acting force of the drainage piece is avoided. In this way, the risk of liquid drop splashing of the air conditioning equipment with the liquid drop visual effect is reduced, the fault rate of the air conditioning equipment is reduced, and waste of atomized liquid is reduced.

[0001] The present application relates to the technical field of air conditioning equipment, in particular to a liquid droplet drainage device and air conditioning equipment. BACKGROUND

[0002] In the air conditioning equipment such as humidifiers and aromatherapy machines, it is usually necessary to atomize the liquid in the liquid tank through an atomizing device, and then adjust the air through the atomized liquid, so as to improve the humidity of the air and make the air fresher.

[0003] In order to make the performance of the air conditioning equipment more diverse, a device that embodies the visual effect of liquid droplets or light is arranged in the air conditioning equipment to improve the market competitiveness of the air conditioning equipment.

[0004] However, in the process of realizing the visual effect of liquid droplets, liquid droplets are often splashed or intrude into the circuit inside the air conditioning equipment, which not only causes the liquid droplets to splash around the air conditioning equipment and cause dirt and waste of atomized liquid, but also increases the risk of failure of the air conditioning equipment.

[0005] Therefore, how to reduce the risk of liquid droplet splashing of the air conditioning equipment with liquid droplet visual effect is a technical problem to be solved. CONTENT OF THE INVENTION

[0006] The liquid droplet drainage device and air conditioning equipment provided by the present application aim to solve the technical problem of how to reduce the risk of liquid droplet splashing of the air conditioning equipment with liquid droplet visual effect in the prior art.

[0007] The liquid droplet drainage device provided by the present application comprises:

[0008] A liquid guide cylinder is provided with a liquid guide channel for restraining liquid droplets.

[0009] A drainage member is arranged in the liquid guide channel, and the drainage member comprises a drainage main body and a sharp portion. The sharp portion is protruded at the end of the drainage main body, and the sharp portion faces the liquid droplet inlet of the liquid guide channel.

[0010] Optionally, the shape of the drainage main body is cylindrical, and the sharp portion is located on the central axis of the drainage main body.

[0011] Optionally, the side wall of the liquid guide channel is cylindrical, and the central axis of the liquid guide channel is collinear with the central axis of the drainage main body.

[0012] Optionally, a gap is arranged between the liquid guide cylinder and the drainage member.

[0013] Optionally, the sharp portion is located inside the liquid guide channel.

[0014] Optionally, a liquid guiding curve is arranged between the tip and the drainage main body, and the liquid guiding curve is used for smoothly transitioning between the tip and the profile of the end of the drainage main body.

[0015] Optionally, the cross-sectional profile of the liquid guiding curve is a parabola.

[0016] Optionally, the drainage member is provided with an isolation chamber, a light-emitting module is arranged in the isolation chamber, and the drainage member is configured to be transparent at least between the tip and the drainage main body.

[0017] The light emitted by the light-emitting module at least transmits from the tip.

[0018] Optionally, a sealing member is arranged at the bottom of the isolation chamber, and the sealing member is used for sealing the isolation chamber to form a water-tight space.

[0019] In another aspect, the application also provides an air conditioning device, which comprises:

[0020] The liquid droplet drainage device is used for draining liquid droplets.

[0021] A liquid droplet generating device is arranged above the liquid droplet drainage device, and the liquid droplets generated by the liquid droplet generating device drop into the liquid guiding channel of the liquid droplet drainage device.

[0022] The application achieves the following beneficial effects: When liquid droplets drop into the liquid droplet drainage device, the liquid droplets enter the liquid guiding channel and then contact the tip of the drainage member. After the liquid droplets contact the tip of the drainage member, the surface of the liquid droplets is punctured by the tip, thereby breaking the surface tension of the liquid droplets and enabling the liquid droplets to flow along the outer wall of the drainage member from the tip to the drainage main body, thereby avoiding splashing of the liquid droplets. In the process of flowing of the liquid droplets along the outer wall of the drainage member, the inner wall of the liquid guiding channel restricts the outside of the liquid droplets, thereby avoiding the liquid droplets from spreading too much outward under the reaction force of the drainage member. In this way, the risk of splashing of the liquid droplets of the air conditioning device with a liquid droplet visual effect is reduced, the failure rate of the air conditioning device is reduced, and the waste of atomized liquid is reduced.

[0034] Please refer to Figures 1 to 3 In some embodiments of the present application, the present application provides an air conditioning device 10, comprising: a liquid droplet guiding device 30 and a liquid droplet generating device 20. The liquid droplet guiding device 30 is used to guide the liquid droplets. The liquid droplet generating device 20 is located above the liquid droplet guiding device 30, and the liquid droplets generated by the liquid droplet generating device 20 fall into the liquid guiding channel 32 of the liquid droplet guiding device 30.

[0035] In the process of working of the air conditioning device 10, liquid droplets are generated by the liquid droplet generating device 20, thereby forming a visual effect of liquid droplets. After the liquid droplet generating device 20 generates liquid droplets, the liquid droplets fall into the liquid guiding channel 32. When the liquid droplets fall into the liquid droplet guiding device 30, the liquid droplets enter the liquid guiding channel 32 and then contact the tip 35 of the guiding member 33. When the liquid droplets contact the tip 35 of the guiding member 33, the surface of the liquid droplets is pierced by the tip 35, thereby breaking the surface tension of the liquid droplets, allowing the liquid droplets to flow along the outer wall of the guiding member 33 from the tip 35 to the main body 34 of the guiding member 33, thereby avoiding splashing of the liquid droplets. In the process of flowing of the liquid droplets along the outer wall of the guiding member 33, the inner wall of the liquid guiding channel 32 restricts the outside of the liquid droplets, thereby avoiding the liquid droplets from spreading too much outward under the reaction force of the guiding member 33. In this way, the risk of splashing of the liquid droplets of the air conditioning device 10 with the visual effect of liquid droplets is reduced, the failure rate of the air conditioning device 10 is reduced, and the waste of atomized liquid is reduced.

[0036] In some embodiments of the present application, the liquid droplet generating device 20 comprises a liquid pump and a liquid droplet device, the liquid droplet device is provided with a liquid droplet outlet, the liquid droplet outlet is located directly above the inlet of the liquid guiding channel 32.

[0037] The atomized liquid is pumped to the liquid droplet device by the liquid pump, and then the atomized liquid is dripped from the liquid droplet outlet to form liquid droplets and fall into the liquid guiding channel 32. In this way, the air conditioning equipment 10 forms the visual effect of liquid droplets.

[0038] Referring to Figures 1 to 3 In some embodiments of the present application, the present application provides a liquid droplet guiding device 30, comprising a liquid guiding cylinder 31 and a guiding member 33. The liquid guiding cylinder 31 is provided with a liquid guiding channel 32 for restraining liquid droplets. The guiding member 33 is arranged in the liquid guiding channel 32, and the guiding member 33 comprises a guiding body 34 and a sharp portion 35, the sharp portion 35 is protruded from the end of the guiding body 34, and the sharp portion 35 is directed towards the liquid droplet inlet of the liquid guiding channel 32.

[0039] It can be understood that when the liquid droplet falls into the liquid droplet guiding device 30, the liquid droplet enters the liquid guiding channel 32 and then contacts the sharp portion 35 of the guiding member 33. When the liquid droplet contacts the sharp portion 35 of the guiding member 33, the surface of the liquid droplet is pierced by the sharp portion 35, thereby breaking the surface tension of the liquid droplet, allowing the liquid droplet to flow along the outer wall of the guiding member 33 from the sharp portion 35 to the guiding body 34, thereby avoiding splashing of the liquid droplet. In the process of the liquid droplet flowing along the outer wall of the guiding member 33, the inner wall of the liquid guiding channel 32 restrains the outside of the liquid droplet, thereby avoiding the liquid droplet from spreading too much outward under the reaction force of the guiding member 33. In this way, the risk of splashing of the liquid droplet of the air conditioning equipment 10 with the visual effect of liquid droplets is reduced, the failure rate of the air conditioning equipment 10 is reduced, and the waste of atomized liquid is reduced.

[0040] Referring to Figures 2 to 3 In some embodiments of the present application, the guiding body 34 is cylindrical in shape, and the sharp portion 35 is located on the central axis of the guiding body 34.

[0041] By configuring the guiding body 34 to be cylindrical in shape and locating the sharp portion 35 on the central axis of the guiding body 34, the force on the surface of the liquid droplet after being pierced by the sharp portion 35 is more uniform, the influence of the reaction force of the outer wall of the guiding member 33 on the liquid droplet is reduced, and the liquid droplet can flow better along the outer wall of the guiding member 33, further reducing the risk of splashing of the liquid droplet.

[0042] Referring to Figure 3 In some embodiments of the present application, the side wall of the liquid guiding channel 32 is cylindrical, and the central axis of the liquid guiding channel 32 is collinear with the central axis of the guiding body 34.

[0043] By configuring the side wall shape of the liquid guide channel 32 and the shape of the drainage main body 34 as cylindrical shapes, and making the central axis of the liquid guide channel 32 and the central axis of the drainage main body 34 collinear, the forces on the inside and outside of the liquid droplet are more uniform. Since the inside of the liquid droplet adheres to the outer wall of the drainage member 33 during the process of flowing along the outer wall of the drainage member 33, and the expansion range of the outside of the liquid droplet is constrained by the side wall of the liquid guide channel 32, by configuring the cylindrical shape, the forces on the liquid droplet in all directions in the circumferential range are balanced, thereby avoiding splashing of the liquid droplet caused by uneven forces. By making the central axis of the liquid guide channel 32 and the central axis of the drainage main body 34 collinear, the distance from the drainage member 33 to the liquid guide channel 32 in the circumferential range of the liquid droplet is uniform, thereby further improving the uniformity of the forces on the liquid droplet and further reducing the risk of splashing of the liquid droplet.

[0044] In some embodiments of the present application, a gap is provided between the liquid guide cylinder 31 and the drainage member 33.

[0045] By providing a gap between the liquid guide cylinder 31 and the drainage member 33, the liquid droplet is prevented from being accumulated between the liquid guide cylinder 31 and the drainage member 33, and the liquid droplet can smoothly flow out from between the liquid guide cylinder 31 and the drainage member 33, and then reach the liquid tank of the air conditioning device 10, thereby realizing the circulating flow of the liquid droplet.

[0046] Please refer to Figure 3 In some embodiments of the present application, the tip 35 is located inside the liquid guide channel 32.

[0047] By locating the tip 35 inside the liquid guide channel 32, the liquid droplet contacts the tip 35 of the drainage member 33 after entering the liquid guide channel 32, so that the liquid droplet is constrained by the side wall of the liquid guide channel 32 before contacting the drainage member 33, and even if the liquid droplet spreads outward due to the reaction force of the drainage member 33, splashing will not occur.

[0048] In some embodiments of the present application, a liquid guide curved surface 36 is provided between the tip 35 and the drainage main body 34, and the liquid guide curved surface 36 is used to smoothly transition between the profile of the tip 35 and the end of the drainage main body 34.

[0049] By forming a smooth transition between the liquid guide curved surface 36 between the tip 35 and the drainage main body 34 of the drainage member 33, the reaction force of the drainage member 33 on the liquid droplet during the process of flowing from the tip 35 to the drainage main body 34 is reduced, and the risk of splashing of the liquid droplet is further reduced.

[0050] In some embodiments of the present application, the cross-sectional profile of the liquid guide curved surface 36 is a parabola.

[0051] Since the direction of the force acting on the liquid droplet by the drainage member 33 is perpendicular to the outer surface of the drainage member 33, the cross-sectional profile shape of the liquid guide curved surface 36 is configured as a parabola, so that the direction of the force acting on the liquid droplet changes along the trajectory of the parabola, on the one hand, the change of the force direction along the trajectory of the parabola can effectively improve the reduction speed of the force acting on the liquid droplet, so that the force acting on the liquid droplet by the drainage member 33 is reduced more quickly, on the other hand, the liquid droplet flows along the trajectory of the parabola along the liquid guide curved surface 36, so that the diffusion direction of the outer part of the liquid droplet converges more to the drainage member 33, and the diffusion range of the liquid droplet after the force acting on the liquid droplet by the drainage member 33 is reduced. In this way, the risk of splashing of the liquid droplet is further reduced.

[0052] In some embodiments of the present application, the drainage member 33 is provided with an isolation chamber 37, and a light-emitting module 40 is arranged in the isolation chamber 37, and the drainage member 33 is at least configured to be transparent between the tip 35 and the drainage body 34. Wherein the light emitted by the light-emitting module 40 at least transmits from the tip 35.

[0053] By arranging the light-emitting module 40 in the drainage member 33, on the one hand, the air conditioning device 10 has the visual effect of light, and on the other hand, the light-emitting module 40 is protected by the drainage member 33, avoiding the erosion of the liquid droplet to the light-emitting module 40, and improving the reliability of the light-emitting module 40. By making the light emitted by the light-emitting module 40 transmit from the tip 35 of the drainage member 33, and then gathering the light through the tip 35, a better visual effect of light is ensured.

[0054] Please refer to Figure 3 In some embodiments of the present application, a sealing member 38 is arranged at the bottom of the isolation chamber 37, and the sealing member 38 is used to seal the isolation chamber 37, so that the isolation chamber 37 forms a water-tight space.

[0055] By sealing the isolation chamber 37 by the sealing member 38, the isolation chamber 37 forms a water-tight space, thereby avoiding the backflow of the liquid droplet into the isolation chamber 37, and further reducing the risk of erosion of the liquid droplet to the light-emitting module 40, and further improving the reliability and service life of the light-emitting module 40.
