Example 1

Referring to fig. 1-12, the present embodiment provides an oxygen injector comprising: a housing 1, a gas delivery device 2 and a liquid storage portion 3 accommodated in the housing 1, and an atomizer 4;

a venturi structure 32 is arranged at the liquid outlet 31 of the liquid storage part 3, the second air outlet 22 of the air conveying device 2 is communicated with a first opening 321 of the venturi structure 32, and the liquid outlet 31 is communicated with a second opening 322 of the venturi structure 32; the first opening 321 to the second opening 322 have a structure with gradually enlarged opening caliber, so that the gas flowing through the first opening and the second opening generate venturi effect; when the gas passes through the venturi structure 32, suction is generated at the liquid outlet 31 of the liquid storage part 3, so that the cosmetic liquid in the liquid storage part 3 is sucked out and enters the liquid inlet 43 through the pipeline. The gas output from the gas delivery device 2 is accelerated by the spiral acceleration channel 45, and then the liquid input from the liquid inlet 43 is blown into mist and output from the mist outlet 44.

According to the oxygen injection device, a user only needs to store the required cosmetic liquid in the liquid storage part 3, and then the cosmetic liquid can be scattered through gas to form spray to be sprayed on the face of the user or the skin of other parts.

In this embodiment, in order to achieve the effect of dispersing the cosmetic liquid by the gas in the atomizer 4, the atomizer body 41 includes an inner seat 411, a liquid inlet pipe 412, an air inlet pipe 413 and a nozzle 414;

the side surface of the inner seat 411 is provided with the air inlet 42 and the liquid inlet 43 respectively; the air inlet 42 and the liquid inlet 43 are respectively communicated with the air conveying device 2 and the liquid storage part 3 through an air inlet pipe 413 and a liquid inlet pipe 412; the nozzle 414 is connected to one end of the inner seat 411, the nozzle 414 has a cavity 417, the bottom of the cavity 417 is provided with the mist outlet 44, and the sidewall of the cavity 417 is provided with the spiral accelerating channel 45 along the circumferential direction;

one end of the inner seat 411 is inserted into the cavity 417 to form a first flow passage 415 communicating with the air inlet and the spiral acceleration channel 45 between the inner seat 411 and the cavity 417; a second flow passage 416 is arranged in the inner seat 411 and is communicated with the liquid inlet and the mist outlet 44; thus, the first flow passage 415 and the second flow passage 416 are not interfered with each other, the gas is accelerated in the spiral accelerating passage 45 through the second flow passage 416, the liquid can flow in the first flow passage 415, and when the cosmetic liquid flows into the mist outlet 44 from the first flow passage 415, the gas enters the mist outlet 44 after being accelerated, so that the purpose that the accelerated gas breaks up the cosmetic liquid at the mist outlet 44 can be realized.

In order to realize the function of delivering gas by the gas delivery device, the gas delivery device 2 in this embodiment is a piston pump, and comprises a pump body 23, two ends of the pump body 23 along the axial direction are respectively provided with an opening surface, and the side wall of the pump body 23 is provided with an air suction valve 24 and a non-return piece 25; one of the opening surfaces is provided with a one-way valve 26, one end of a piston 27 extends into the pump body 23 through the other opening surface, the other end of the piston 27 is connected with a cam connecting rod 28, the cam connecting rod 28 is matched with a cam mechanism 291 of a gear 29, an output rotating shaft of a motor 292 is meshed with the gear 29, and rotation output by the motor 292 is reversed to the gear 29 to drive the cam connecting rod 28 and the piston 27 to reciprocate along the axial direction of the pump body 23. A variable chamber is formed between the piston 27 and the pump body 23, and the volume of the variable chamber is periodically increased and decreased when the piston 27 reciprocates. When the volume of the variable chamber increases, the air pressure in the variable chamber decreases, and outside air enters the variable chamber through the air suction valve 24; when the volume of the variable chamber decreases, the air pressure in the variable chamber increases, and since the check plate 25 is attached to the suction valve 24, air cannot flow out from the suction valve 24, but only from the check valve 26. This achieves the purpose of intermittently outputting gas at the check valve 26. In order to make the output gas realize the functions of breaking up the functional liquid and generating suction force into the venturi structure 32, the first air outlet 21 and the second air outlet 22 are respectively communicated with the check valve 26.

In addition, since the cosmetic liquid to be sprayed by the user using the oxygen injector is different from each other, there is a relatively large difference between the viscosity of the different cosmetic liquids, and if the most viscous cosmetic liquid can be sucked out, the suction force generated by the venturi structure 32 is required to be sufficiently large. However, if this suction force is too large, once the viscosity of the user using the beauty instrument becomes low, the suction force is so large that excessive beauty liquid is sucked out, resulting in waste of the beauty liquid.

Therefore, a structure is required to make the suction force generated by the venturi structure 32 adjustable so as to adapt to the cosmetic liquid with different viscosity for use. For this purpose, a regulating valve 5 is also connected between the second outlet 22 of the gas delivery device 2 and the venturi structure 32, said regulating valve 5 being used to regulate the flow rate or flow of the gas entering the venturi structure 32.

Specifically, the regulating valve 5 includes a housing 51, a gear motor 52, a second gear 53, and a threaded needle 54;

the output rotating shaft of the gear motor 52 is meshed with a second gear 53, and the second gear 53 is fixedly connected with a threaded needle 54. One end of the threaded needle 54 is inserted into the housing 51 by screw-fitting, and a portion of the threaded needle 54 inserted into the housing 51 has a seal ring 55 fitted to an inner wall of the housing 51. When the gear motor 52 drives the second gear 53 to rotate, the threaded needle 54 moves relative to the housing 51 through threaded engagement, so that the depth of the threaded needle 54 inserted into the housing 51 is changed, a gap for air to flow through is formed between the threaded needle 54 and the housing 51, and the flow area of the gap is gradually increased along with the movement of the threaded needle 54; thus, as the flow area increases, the flow of gas into the venturi structure 32 increases, and the suction created at the venturi structure 32 increases.

Finally, the liquid storage portion 3 in this embodiment is divided into a liquid storage bottle 33 and a base 34, and the liquid storage bottle 33 and the base 33 are detachably connected, so that a user can freely replace different liquid storage bottles 32, and the purpose of replacing different cosmetic liquids is achieved.

Example 2

Referring to fig. 13-23, the present embodiment provides an oxygen injector comprising: a housing 1, a gas delivery device 2 and a liquid storage portion 3 accommodated in the housing 1, and an atomizer 4;

a venturi structure 32 is arranged at the liquid outlet 31 of the liquid storage part 3, the second air outlet 22 of the air conveying device 2 is communicated with a first opening 321 of the venturi structure 32, and the liquid outlet 31 is communicated with a second opening 322 of the venturi structure 32; the first opening 321 to the second opening 322 have a structure with gradually enlarged opening caliber;

when the gas passes through the venturi structure 32, suction is generated at the liquid outlet 31 of the liquid storage part 3, so that the cosmetic liquid in the liquid storage part 3 is sucked out and enters the liquid inlet 43 through the pipeline. The gas output from the gas delivery device 2 is accelerated by the spiral acceleration channel 45, and then the liquid input from the liquid inlet 43 is blown into mist and output from the mist outlet 44.

In this embodiment, in order to achieve the effect of dispersing the cosmetic liquid by the gas in the atomizer 4, a first flow passage 411 is disposed in the atomizer body 41 and is communicated between the liquid inlet 43 and the mist outlet 44, and a second flow passage 412 is formed between the first flow passage 411 and the inner side wall of the atomizer body 41 and is communicated with the air inlet 42. Thus, the first flow channel 411 and the second flow channel 412 are not interfered with each other, gas can accelerate in the second flow channel 412, liquid can flow in the first flow channel 411, and when the cosmetic liquid flows into the mist outlet 44 from the first flow channel 411, the gas enters the mist outlet 44 after being accelerated, so that the purpose that the accelerated gas breaks up the cosmetic liquid at the mist outlet 44 can be realized.

In this embodiment, in order to achieve the spiral acceleration effect, a partition 46 is disposed in the second flow channel 412 along the circumferential direction, and the partition 46 divides the second flow channel 412 into a plurality of spiral acceleration channels 45. Specifically, the dividing member 46 is a silica gel sleeve, which is sleeved outside the side wall of the first flow channel 411; and the side wall of the silica gel cover is provided with the spiral accelerating channel 45 along the circumferential direction. Thus, when the silica gel sleeve is sleeved outside the first flow passage 411, the parts of the second flow passage 412 except the spiral accelerating passage 45 are blocked by the silica gel sleeve, and the gas can only enter the spiral accelerating passage 45 for accelerating, so that the accelerating effect of the gas is ensured.

In this embodiment, the gas delivery device 2 is an air pump, and the first air outlet 21 and the second air outlet 22 on the air pump are connected with the atomizer 4 and the venturi structure 32 by using a hose, so that the structure is further simplified compared with the scheme of embodiment 1.

Therefore, a structure is required to make the suction force generated by the venturi structure 32 adjustable so as to adapt to the cosmetic liquid with different viscosity for use. For this purpose, a regulating valve 55 is also connected between the second outlet 22 of the gas delivery device 2 and the venturi structure 32, said regulating valve 55 being used to regulate the flow rate or flow of the gas entering the venturi structure 32.

the output rotating shaft of the gear motor 52 is meshed with a second gear 53, and the second gear 53 is fixedly connected with a threaded needle 54. One end of the threaded needle 54 is inserted into the housing 51 by screw-fitting, and a portion of the threaded needle 54 inserted into the housing 51 has a seal ring fitted to an inner wall of the housing 51. When the gear motor 52 drives the second gear 53 to rotate, the threaded needle 54 moves relative to the housing 51 through threaded engagement, so that the depth of the threaded needle 54 inserted into the housing 51 is changed, a gap 55 for air to flow through is formed between the threaded needle 54 and the housing 51, and the flow area of the gap 55 is gradually increased along with the movement of the threaded needle 54; thus, as the flow area increases, the flow of gas into the venturi structure 32 increases, and the suction created at the venturi structure 32 increases.

The movement of the screw needle 54 is divided into three steps in this embodiment, wherein the screw needle 54 is in a state of sealing connection with the housing 51 in the initial state, and the air in the second air outlet 22 is not allowed to flow into the venturi structure 32. When the user selects first gear, the threaded needle 54 moves back 0.7mm relative to the housing 51, at which time the threaded needle 54 opens a small opening with the housing 51, the flow of gas into the venturi structure 32 is minimized, and the suction created is minimized, which is suitable for use with relatively low viscosity cosmetic fluids. When the user selects the second gear, the threaded needle 54 continues to move backwards by 0.7mm relative to the housing 51, and at this time, the threaded needle 54 and the housing 51 are opened with a larger opening, the flow rate of the gas entering the venturi structure 32 is larger, and the generated suction force is also larger, so that the device is suitable for the cosmetic liquid with higher viscosity. When the user selects third gear; the threaded needle 54 continues to move 0.7mm rearward relative to the housing 51, at which point the threaded needle 54 opens the largest opening with the housing 51, the flow of gas into the venturi structure 32 is greatest, and the suction created is greatest, so that it is suitable for use with the highest viscosity cosmetic liquid.

Finally, the liquid storage portion 3 in this embodiment is divided into a liquid storage bottle 32 and a base 33, and the liquid storage bottle 32 and the base 33 are detachably connected, so that a user can freely replace different liquid storage bottles 32, and the purpose of replacing different cosmetic liquids is achieved.

The foregoing is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present utility model within the scope of the present utility model disclosed herein by this concept, which falls within the actions of invading the protection scope of the present utility model.
