[0036] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention.

[0037] The utility model provides a double-chamber skin liquid sprayer, such as Figure 1 and Figure 2 As shown, it includes an externally threaded non-full-circular piece 2, a hollow threaded cover 3, a double-nozzle device 4 and two liquid storage barrels 1; the two liquid storage barrels 1 can be assembled into a cylindrical shape, and the upper end of the liquid storage barrel 1 is provided with an externally threaded non-full-circular piece 2, and the two externally threaded non-full-circular pieces 2 are both threadedly connected to the hollow threaded cover 3, and the middle part of the hollow threaded cover 3 is slidably connected to the double-nozzle device 4.

[0038] The two externally threaded non-full-circular sheets 2 cooperate with the hollow threaded cover 3 to realize the assembly and positioning of the two liquid storage barrels 1.

[0039] The double nozzle device 4 sprays the two liquid barrels 1 from different channels to avoid the crossover of the liquid medicine. At the same time, the design of integrating two liquid medicine spraying channels saves space.

[0040] like Figure 4 As shown, the double nozzle device 4 includes a lifting component 41, a nozzle component 42, a pressure supply component 43 and a liquid supply pipe 44; a pressure supply component 43 is provided in the middle of the lifting component 41, and nozzle components 42 are provided on both sides of the lifting component 41, and the lower end of the nozzle component 42 is connected to the liquid supply pipe 44; there is one pressure supply component 43; when the pressure supply component 43 and the nozzle component 42 on one side are pressed, the nozzle component 42 on the other side sprays out the liquid inside.

[0041] The lifting component 41 is used to enable the spray head component 42 to have the function of lifting and lowering. The spray head component 42 is used to spray liquid medicine or moisturizing water. The pressure supply component 43 is used to supply pressure to the spray head component 42.

[0042] Preferably, Figure 5As shown, the lifting component 41 includes a pressure plate 411, a first one-way air intake valve 413, a first fixed sleeve 414, a first movable sleeve 415 and a first telescopic spring 416; the first one-way air intake valve 413 and the first fixed sleeve 414 are provided on both sides of the upper end of the pressure plate 411, the first movable sleeve 415 is sleeved inside the first fixed sleeve 414, and the first telescopic spring 416 is sleeved outside the first movable sleeve 415.

[0043] Since the pressing plate 411 , the first fixed sleeve 414 , the first movable sleeve 415 and the liquid storage barrel 1 together form a closed space, air is introduced through the first one-way air inlet valve 413 to ensure the pressure balance of the closed space.

[0044] The first telescopic spring 416 is configured to contract when subjected to downward pressure, and to return to its original position when the downward pressure disappears.

[0045] Preferably, Figure 6 As shown, the nozzle component 42 includes a nozzle rack 421, a second one-way liquid inlet valve 422, an elastic diaphragm 423, a second one-way liquid outlet valve 424, a conduit 425 and an atomizing head 426; the two nozzle racks 421 are arranged on both sides of the pressure supply component 43, and a liquid transfer groove is opened inside the nozzle rack 421, and a second one-way liquid outlet valve 424 and a second one-way liquid inlet valve 422 are respectively provided at the upper and lower ends of the liquid transfer groove, and the second one-way liquid outlet valve 424 is connected to the atomizing head 426 through a conduit 425, and an elastic diaphragm 423 is provided on the opening side of the liquid transfer groove, and the opening of the liquid transfer groove faces the pressure supply component 43.

[0046] The working principle of the spray head component 42 is that when the pressure supply component 43 applies pressure to one side of the elastic diaphragm 423, the elastic diaphragm 423 expands, squeezing the liquid in the medicine liquid transfer tank, and the liquid is sprayed out from the atomizing head 426 through the second one-way liquid outlet valve 424 and the conduit 425. When the pressure provided by the pressure supply component 43 to the elastic diaphragm 423 disappears, the elastic diaphragm 423 resets itself by relying on its own elasticity. During the reset process, negative pressure is formed in the medicine liquid transfer tank, and the liquid in the liquid storage barrel 1 enters the medicine liquid transfer tank through the liquid supply pipe 44 and the second one-way liquid inlet valve 422.

[0047] Preferably, Figure 7 As shown, the pressure supply member 43 includes a lower pressure frame 431, a breathable strip vertical hole 432, a second telescopic spring 433 and a fixed sleeve 434; the fixed sleeve 434 is slidably connected to the lower pressure frame 431 on the outside, and breathable strip vertical holes 432 are opened on both sides of the lower pressure frame 431, and a second telescopic spring 433 is installed inside the lower pressure frame 431.

[0048] The pressure supply component 43 and one side of the nozzle frame 421 are pressed at the same time, and the lower pressure frame 431 is pressed downward. The space formed by the lower pressure frame 431 and the fixed sleeve frame 434 is compressed, and the pressure increases. When the pressure is pressed down to the elastic diaphragm 423 of the nozzle frame 421 on the other side, the pressure can be transferred to the elastic diaphragm 423 of the nozzle frame 421 on the other side through the breathable strip vertical hole 432, thereby realizing the pressure supply function.

[0049] Preferably, the two liquid storage barrels 1 are respectively provided with corresponding convex blocks and concave grooves on the joint surfaces formed into a cylindrical shape, and the convex blocks and concave grooves are used to facilitate the jointing of the two liquid storage barrels 1.

[0050] Preferably, Figure 3 As shown, a circular column piece 11 is provided at the upper end of the liquid storage barrel 1.

[0051] Preferably, circular rubber pads 412 corresponding to the positions of the annular column pieces 11 are provided on both sides of the lower end of the pressing plate 411 to form a closed space to prevent the liquid in the liquid storage barrel 1 from shaking out when the barrel body is shaken.

[0052] Preferably, after the two liquid storage barrels 1 are assembled into a cylindrical shape, there is a gap when they are matched with the hollow threaded cover 3, and the gap can connect the inside and the outside of the hollow threaded cover 3.

[0053] Preferably, the spray head component 42 and the pressure supply component 43 form a cylinder.

[0054] Preferably, a cap is installed on the upper portion of the hollow threaded cover 3.

[0055] When using this sprayer:

[0056] Two different types of liquids (such as anti-allergic liquid and moisturizing water or two different liquids) are added to the two liquid storage barrels 1 respectively. After the addition is completed, the two liquid storage barrels 1 are assembled. The convex round blocks and concave round grooves of the liquid storage barrels 1 can facilitate the determination of the position when assembling. After the assembly is completed, the double nozzle device 4 is installed. The circular rubber pad 412 of the double nozzle device 4 is placed on the circular column sheet 11 of the liquid storage barrel 1. After the completion, the hollow threaded cover 3 is installed. The threads on the hollow threaded cover 3 cooperate with the external threaded non-full-circular sheet 2 to fix the position of the double nozzle device 4. At this time, the liquid filling and assembly of the sprayer are completed;

[0057] When one of the liquids is needed (such as the anti-allergic liquid filled in the liquid storage barrel 1 on the left), the right spray head component 42 and the middle pressure supply component 43 are pressed at the same time. At this time, the right spray head component 42 moves downward under the action of the lifting component 41, and the lower pressure frame 431 of the middle pressure supply component 43 moves downward synchronously with the right spray head component 42 under the action of the second telescopic spring 433. The pressure in the space formed by the lower pressure frame 431 and the fixed sleeve 434 increases. When the gas in the space formed by the lower pressure frame 431 and the fixed sleeve 434 is pressed down and can be transferred to the elastic diaphragm 423 on the left through the breathable strip vertical hole 432, the elastic diaphragm 423 expands under the action of pressure, squeezing the liquid in the liquid transfer tank of the left spray head component 42. The liquid in the liquid transfer tank (anti-allergic liquid) is sprayed from the atomizing head 426 through the second one-way liquid outlet valve 424 and the conduit 425 in the left spray head component 42 in turn.

[0058] When the right side spray head component 42 and the middle pressure supply component 43 are no longer pressed, the right side spray head component 42 and the middle pressure supply component 43 are reset under the action of the first telescopic spring 416 and the second telescopic spring 433. During the reset process, the space formed by the lower pressure frame 431 and the fixed sleeve frame 434 increases, the pressure decreases, the elastic diaphragm 423 gradually resets, and the space of the liquid transfer tank of the left side spray head component 42 increases to form a negative pressure. The liquid (anti-allergic liquid) in the left side liquid storage barrel 1 enters the left side liquid transfer tank through the left side liquid supply pipe 44 and the second one-way liquid inlet valve 422 in turn, thereby realizing the liquid replenishment of the liquid transfer tank.

[0059] When another liquid is needed (such as moisturizing liquid added to the liquid storage barrel 1 on the left), the principle is the same as above.

[0060] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
