[0024] The features of the present utility model and other related features are further described in detail by the following examples, so as to facilitate the understanding of the same by the technical personnel in the same industry:
[0025] For example, Figures 1 to 6 As shown, a liquid leakage prevention aromatherapy machine when pouring, comprising an aromatherapy machine body, the top of the aromatherapy machine body is provided with a first through hole for releasing atomized aromatherapy liquid, the top of the aromatherapy machine body is sealingly connected with a sealing assembly controlled by gravity, the top of the sealing assembly is provided with a second through hole for releasing atomized aromatherapy liquid outward and opening when the aromatherapy machine is upright and blocking when pouring.
[0026] As described above, the aromatherapy machine of the case is also connected with the sealing assembly on the top of the aromatherapy machine body, and the atomized aromatherapy liquid released from the first through hole on the top of the aromatherapy machine body needs to pass through the sealing assembly to be released to the outside from the second through hole. The sealing assembly can control the opening and closing of the second through hole by gravity. When the aromatherapy machine is vertically placed for normal use, the gravity acting on the sealing assembly overlaps with the axis direction of the sealing assembly, the second through hole will be normally opened, so that the atomized aromatherapy liquid can be normally discharged to the outside. Once the aromatherapy machine is poured, the gravity acting on the sealing assembly will form an angle with the axis of the sealing assembly. At this time, the sealing assembly will block the second through hole to prevent the aromatherapy liquid from leaking to the outside environment, thereby realizing the function of preventing liquid leakage and avoiding the pollution of the aromatherapy liquid leakage to the environment near the aromatherapy machine.
[0027] As Figures 1 to 7 shown, preferably, the sealing assembly comprises a sealing cover threadedly connected to the top of the aromatherapy machine body, the sealing cover is a cover body with an opening facing downward, the second through hole is arranged on the top of the sealing cover, the sealing cover is connected with a fixed support, the fixed support is nested with a movable support capable of moving up and down relative to the fixed support, a compression spring for driving the movable support to move towards the second through hole is arranged between the inner bottom of the fixed support and the outer bottom of the movable support, the fixed support and the movable support are both hollow frame bodies with hollow side walls to facilitate airflow passing through, the top of the movable support is provided with a rubber plug coaxially arranged with the second through hole and a plurality of third through holes for airflow passing through, the movable support is provided with a steel ball capable of freely moving up and down.
[0028] As described above, the sealing assembly of the case includes a fixed support and a movable support which are nested and capable of moving relative to each other, both supports are hollow frame bodies with hollow side walls, and the movable support is further provided with a third through hole at the top, so that the atomized aromatherapy liquid can pass through the two supports and be discharged from the second through hole after coming out of the first through hole. Meanwhile, the sealing assembly of the case further includes a rubber plug arranged at the top of the movable support, a steel ball freely moving up and down in the movable support, and a compression spring located between the fixed support and the movable support, so that when the aromatherapy machine is normally vertically placed, the movable support can move downward under the gravity of the steel ball to overcome the elastic force of the compression spring, so that the rubber plug can move away from the second through hole to normally open the second through hole. When the aromatherapy machine is tilted, the gravity of the steel ball cannot be used to help the movable support overcome the elastic force of the compression spring, and the compression spring will drive the movable support to move towards the second through hole, so that the rubber plug will also move towards the second through hole to block the second through hole, thereby preventing the aromatherapy liquid from leaking out of the second through hole.
[0029] Preferably, the compression spring has an elastic coefficient k, a length L1 when naturally vertically placed on a plane, and a length L2 when the movable support moves to the limit position in the direction of the second through hole, and L1>L2, the total mass of the movable support, the steel ball and the rubber plug is m, and the gravitational acceleration is g, then mg>k, so as to ensure that when the aromatherapy machine is vertically placed, the deformation of the compression spring under the gravity of the movable support, the steel ball and the rubber plug is sufficient to move the rubber plug away from the second through hole, and on this basis, the sensitivity of the sealing assembly can be changed by further adjusting the weight of the steel ball and the parameters of the compression spring.
[0030] As shown in Figure 2 , Figure 4 and Figure 5 , preferably, the top of the aromatherapy machine body is provided with an atomization joint, the first through hole is arranged at the upper end of the atomization joint, a liquid storage tank for containing the aromatherapy liquid is connected below the atomization joint, a gas pump for supplying gas is further arranged in the aromatherapy machine body, a liquid taking channel extending to the liquid storage tank and a gas supply channel connected with the gas outlet of the gas pump are arranged in the atomization joint, the liquid outlet of the liquid taking channel and the gas outlet of the gas supply channel are both located below the first through hole and arranged adjacent to each other in a vertical direction.
[0031] As described above, the liquid outlet and the gas outlet in the aromatherapy machine body are arranged adjacent to each other in a vertical direction, so that when the gas pump is working, the aromatherapy liquid in the liquid storage tank will be sucked out from the liquid taking channel and flow out from the liquid outlet by using Bernoulli's principle, and the aromatherapy liquid flowing out of the liquid outlet will be atomized under the impact of the gas flow sprayed from the gas outlet, and the atomized aromatherapy liquid will be discharged from the first through hole in the direction of the overall gas flow, thereby realizing the diffusion of aromatherapy.
[0032] Different from the common aromatherapy machine which atomizes the aromatherapy liquid by ultrasonic wave, the aromatherapy machine body of the present application atomizes the aromatherapy liquid by Bernoulli principle with the help of air pump, and the deployment and maintenance cost of the air pump is lower than that of the ultrasonic atomizer, and the energy consumption of the air pump is also far less than that of the ultrasonic atomizer, so that the manufacturing and use cost of the aromatherapy machine body of the present application can be greatly reduced, thereby improving the product competitiveness.
[0033] As shown in Figure 5 , preferably, the diameter of the liquid outlet is D, the diameter of the gas outlet is also D, the D = 0.25 mm, and the diameters of the rest of the liquid taking channel and the gas supply channel are smaller than those of the liquid outlet and the gas outlet, respectively, so that the gas flow rate at the gas outlet can be increased by using a small-diameter gas outlet, thereby generating a larger pressure difference to facilitate the suction of the aromatherapy liquid, and the flow rate of the aromatherapy liquid can be reduced by using a small-diameter liquid outlet, thereby achieving a more delicate atomization effect.
[0034] As shown in Figure 2 , preferably, the top of the aromatherapy machine body is provided with a plurality of first through holes, so that the atomized aromatherapy liquid can be discharged from multiple positions of the atomization joint, avoiding the atomized aromatherapy liquid from being re-liquefied before being discharged.
[0035] As shown in Figure 4 and Figure 5 , preferably, the sealing assembly forms a transfer cavity between the first through hole and the second through hole for the atomized aromatherapy liquid to pass through, so that the atomized aromatherapy liquid with larger particles is more likely to adhere to the wall of the transfer cavity and be re-liquefied when passing through the transfer cavity, thereby being unable to be discharged, which can ensure that the atomized aromatherapy liquid discharged from the second through hole is small in particle size, thereby achieving a more delicate atomization effect.
[0036] As shown in Figures 3 to 7 , preferably, the side wall of the fixed support is provided with a plurality of upward and downward extending guide grooves, and the side wall of the movable support is a guide column corresponding to the guide grooves, and the guide column moves up and down in the guide groove, so that the guide groove and the guide column can cooperate to ensure that the movable support can move up and down in the fixed support, and the guide column is embedded in the guide groove, and the steel ball does not contact the guide column in the movable support, so that the guide groove and the steel ball do not clamp the guide column in the middle, thereby hindering the movement of the movable support and causing the liquid leakage prevention function to fail.
[0037] As described above, the present application protects a kind of aromatherapy machine that prevents liquid leakage when pouring, and all technical solutions identical or similar to the present application shall be regarded as falling within the protection scope of the present application.
