[0028] The present invention provides a spray can 100 .

[0029] See also Figure 1 In the utility model, the spray can 100 includes a tank body 1 and a nozzle 2. The tank body 1 is provided with a first chamber 11 and a second chamber 12 isolated from each other. The first chamber 11 is used to store a first solvent, and the second chamber 12 is used to store a coolant. The nozzle 2 is installed at the bottle mouth of the tank body 1. The nozzle 2 is connected to a spray pipeline to communicate the first chamber 11 and the second chamber 12.

[0030] A conventional spray can 100 is usually provided with only one chamber in the tank body 1 for storing a solvent, and the spray sprayed therefrom does not have a cooling effect. Unlike the conventional spray can 100, the present invention spray can 100 is provided with a partition in the tank body 1 to separate the chambers of the tank body 1 into a first chamber 11 and a second chamber 12 that are isolated from each other, wherein the first chamber 11 is used to store a first solvent, such as a beauty serum, moisturizing water, makeup setting spray, and liquid medicine, etc., and the second chamber 12 is used to store a coolant, such as a gaseous or liquid substance such as pentafluoropropane, tetrafluoroethane, and isobutane, which mainly cools the skin. The nozzle 2 of the spray can 100 is connected to an injection pipeline, which is connected to the first chamber 11 and the second chamber 12, so that the mist solvent sprayed by the spray can 100 carries a coolant component, thereby having a cooling effect, thereby meeting the user's needs for instant cooling and soothing of the skin.

[0031] exist Figure 1 In the embodiment shown, the first chamber 11 and the second chamber 12 are arranged in parallel, and the injection pipeline includes a first branch pipe 21, a second branch pipe 22, and a converging pipe 23 that intersects with the first branch pipe 21 and the second branch pipe 22. The first branch pipe 21 is connected to the first chamber 11, the second branch pipe 22 is connected to the second chamber 12, and the converging pipe 23 is connected to the nozzle 2.

[0032] The converging pipe 23 and the first branch pipe 21 may be the same pipe, or the converging pipe 23 and the second branch pipe 22 may be the same pipe, or the converging pipe 23 may be a third branch pipe independent of the first branch pipe 21 and the second branch pipe 22, which is not limited here.

[0033] exist Figure 2 In the embodiment shown, the first chamber 11 and the second chamber 12 are spaced apart from each other in the upper and lower directions, and the injection pipeline includes a first branch pipe 21, a second branch pipe 22, and a converging pipe 23 connected to the first branch pipe 21 and the second branch pipe 22. The first branch pipe 21 is connected to the first chamber 11, the second branch pipe 22 is connected to the second chamber 12, and the converging pipe 23 is connected to the nozzle 2.

[0034] Thus, the first solvent in the first chamber 11 flows from the first branch pipe 21 into the confluence pipe 23 and is then sprayed out from the nozzle 24, and the coolant in the second chamber 12 flows from the second branch pipe 22 into the confluence pipe 23 and is then sprayed out from the nozzle 24, and the first solvent and the coolant can be mixed in the confluence pipe 23, so that the sprayed first solvent has a cooling effect.

[0035] The spray can 100 further includes a switching device disposed within the can body 1 and extending across the first branch pipe 21 and the second branch pipe 22. The switching device has a first state, a second state, and a third state. When the switching device is in the first state, the first branch pipe 21 is open, the second branch pipe 22 is blocked, and the first solvent flows sequentially through the first branch pipe 21 and the confluence pipe 23 before being sprayed out of the spray head 2. When the switching device is in the second state, the first branch pipe 21 is blocked, the second branch pipe 22 is open, and the coolant flows sequentially through the second branch pipe 22 and the confluence pipe 23 before being sprayed out of the spray head 2. When the switching device is in the third state, both the first branch pipe 21 and the second branch pipe 22 are open, and the first solvent and the coolant flow through the first branch pipe 21 and the second branch pipe 22, respectively, into the confluence pipe 23, where they mix and are sprayed out of the spray head 2.

[0036] This embodiment provides a switching device to control the conduction state of the first branch pipe 21 and the second branch pipe 22. When the switching device is switched to the first state, the first branch pipe 21 is conducted and the second branch pipe 22 is blocked. At this time, when the nozzle 2 is pressed, the first solvent will flow through the first branch pipe 21 and the confluence pipe 23 in sequence and then be sprayed out of the nozzle 2, thereby achieving the separate spraying of the first solvent. When the switching device is switched to the second state, the first branch pipe 21 is blocked and the second branch pipe 22 is conducted. At this time, when the nozzle 2 is pressed, the coolant will flow through the second branch pipe 22 and the confluence pipe 23 in sequence and then be sprayed out of the nozzle 2, thereby achieving the separate spraying of the coolant. When the switching device is switched to the third state, both the first branch pipe 21 and the second branch pipe 22 are conducted. The first solvent and the coolant flow through the first branch pipe 21 and the second branch pipe 22 respectively, enter the confluence pipe 23, mix, and then be sprayed out of the nozzle 2, thereby achieving the mixed spraying of the first solvent and the coolant, thereby meeting the different needs of users.

[0037] For example, in one embodiment of the present invention, the switching device may be a solenoid valve 3, referring to Figure 3 The solenoid valve 3 includes a valve body 31 and a valve core 32. A valve cavity is provided in the valve body 31. The valve core 32 is movably provided in the valve cavity. The side wall of the valve core 32 is fitted with the side wall of the valve cavity. The valve core 32 divides the valve cavity into a first valve cavity 311 and a second valve cavity 313. First flow ports 312 are provided on both sides of the first valve cavity 311, and second flow ports 314 are provided on both sides of the second valve cavity 313. The first branch pipe 21 is connected to the first flow port 312, and the second branch pipe 22 is connected to the second flow port 314. When the solenoid valve 3 switches to the first state, the valve core 32 moves toward the second valve chamber 313, thereby opening the first flow port 312 and blocking the second flow port 314; when the solenoid valve 3 switches to the second state, the valve core 32 moves toward the first valve chamber 311, thereby opening the second flow port 314 and blocking the first flow port 312; when the solenoid valve 3 switches to the third state, the valve core 32 is located in the middle position of the valve body 31, so that the first flow port 312 and the second flow port 314 are both in a half-open state.

[0038] It should be noted that the solenoid valve 3 also includes a solenoid coil (not shown). The valve core 32 is disposed within the magnetic field of the solenoid coil and is movable under the magnetic force of the solenoid coil. When the solenoid valve 3 is switched to the first state, the solenoid coil is energized, and the valve core 32 moves toward the second valve chamber 313 under the magnetic force of the solenoid coil, thereby opening the first flow port 312 and blocking the second flow port 314. At this point, the first branch pipe 21 is open and the second branch pipe 22 is blocked. Pressing the nozzle 2 causes the first solvent to flow through the first branch pipe 21 and the confluence pipe 23 in sequence before being ejected from the nozzle 2, thereby achieving separate ejection of the first solvent. When the solenoid valve 3 is switched to the second state, a reverse current is passed through the solenoid coil, and the valve core 32 moves toward the first valve chamber 311 under the magnetic force of the solenoid coil, thereby blocking the first flow port 312 and opening the second flow port 314. At this time, the first branch pipe 21 is blocked and the second branch pipe 22 is open. Pressing the nozzle 2, the coolant will flow through the second branch pipe 22 and the confluence pipe 23 in sequence before being sprayed out of the nozzle 2, thereby achieving separate spraying of the coolant. When the solenoid valve 3 is switched to the third state, the solenoid coil is de-energized, and the valve core 32 moves to the middle position of the valve body 31, so that the first flow port 312 and the second flow port 314 are both in a half-open state. At this time, the first branch pipe 21 and the second branch pipe 22 are both open. Pressing the nozzle 2, the first solvent and the coolant will flow through the first branch pipe 21 and the second branch pipe 22 respectively, enter the confluence pipe 23, mix, and then be sprayed out of the nozzle 2, thereby achieving mixed spraying of the first solvent and the coolant.

[0039] Furthermore, the solenoid valve 3 also includes a first spring 33 arranged in the first valve chamber 311 and a second spring 34 arranged in the second valve chamber 313, one end of the first spring 33 is connected to the valve core 32, and the other end is connected to the end wall of the first valve chamber 311, one end of the second spring 34 is connected to the valve core 32, and the other end is connected to the end wall of the second valve chamber 313.

[0040] The first spring 33 and the second spring 34 are used to drive the valve core 32 to reset. When the solenoid valve 3 switches to the first state, the valve core 32 moves toward the second valve chamber 313 under the action of the electromagnetic force, the first spring 33 is stretched and the second spring 34 is compressed; when the solenoid valve 3 switches to the second state, the valve core 32 moves toward the first valve chamber 311 under the action of the electromagnetic force, the first spring 33 is compressed and the second spring 34 is stretched; when the solenoid valve 3 switches to the third state, the electromagnetic coil is de-energized, the electromagnetic force disappears, and the valve core 32 moves to the middle position of the valve body 31 under the elastic force of the first spring 33 and the second spring 34, so that the first flow port 312 and the second flow port 314 are both in a half-open state.

[0041] In one embodiment of the present invention, the nozzle 2 includes a nozzle 24 and a water distribution plate (not shown). The nozzle 24 is provided with a plurality of water outlet holes to achieve uniform distribution of the water flow. The water distribution plate is rotatably disposed on the nozzle 24. The water distribution plate is provided with a plurality of water distribution holes. The number and size of the water distribution holes are consistent with the number and size of the water outlet holes. The water distribution plate can then be rotated to adjust the overlapping area between the water distribution holes and the water outlet holes, thereby adjusting the spray angle of the spray. It is not difficult to understand that the smaller the overlapping area between the water distribution holes and the water outlet holes, the smaller the flow area of ​​the water flow. When the water output is consistent, the reduction in the flow area will lead to an increase in the water outlet pressure, thereby increasing the spray angle of the spray, thereby interfering with the adjustment of the spray angle.

[0042] Further, continue to refer to Figure 1 The spray head 2 further comprises a mounting barrel 25, a pump assembly (not shown), and a push-on cap 27. The mounting barrel 25 is mounted at the mouth of the can 1. The pump assembly is disposed within and integrally connected to the mounting barrel 25. The pump assembly includes a piston tube 26, which is connected to the junction pipe 23 of the spray line. The push-on cap 27 is mounted on the mounting barrel 25 so as to be movable up and down and covers the pump assembly. The pump assembly can be a common commercially available spray can pump assembly and will not be described in detail here.

[0043] The mounting tube 25 comprises an outer ring body 251 and an inner ring body 252. The inner ring body 252 is integrally connected to the outer ring body 251 and concentrically arranged. A pressing gap 253 is formed between the outer ring body 251 and the inner ring body 252. The width of the pressing gap 253 is consistent with the thickness of the side wall of the pressing cap 27. The side wall of the pressing cap 27 is partially inserted into the pressing gap 253 to be rotatably connected to the mounting tube 25. Several limit blocks are provided in the pressing gap 253. The limit blocks are protruding from the side walls of the outer ring body 251 or the inner ring body 252. The lower end of the pressing cap 27 is protruding with several stop blocks of varying heights. The limit blocks are used to abut against the stop blocks, thereby limiting the pressing depth of the pressing cap 27.

[0044] It is easy to understand that the spray pressure varies with the depth of the pressing cap 27. In this embodiment, a limit block is provided within the pressing gap 253, and a stopper of varying heights is protruded from the lower end of the pressing cap 27. By rotating the pressing cap 27, the height of the stopper directly opposite the limit block can be adjusted, thereby achieving variable adjustment of the spray pressure.

[0045] by Figure 4For example, a first stopper 254, a second stopper 255, and a third stopper 256 are convexly provided on a surface of the outer ring body 251 or the inner ring body 252 facing the pressing gap 253, and the first stopper 254, the second stopper 255, and the third stopper 256 are staggered in the vertical direction. A first stopper 271, a second stopper 272, and a third stopper 273 are convexly provided on the lower end of the pressing cap 27, and the bottom surface of the first stopper 271 is higher than the bottom surface of the second stopper 272, and the bottom surface of the second stopper 272 is higher than the bottom surface of the third stopper 273.

[0046] The pressing cap 27 has a first rotation position, a second rotation position and a third rotation position. When the pressing cap 27 is rotated to the first rotation position, as shown in FIG. Figure 3 As shown, the first stopper 271 is aligned with the first stopper 254, the second stopper 272 is offset from the second stopper 255, and the third stopper 273 is offset from the third stopper 256. At this point, the pressing cap 27 is in the first position, and the pressing depth of the pressing cap 27 is the distance between the bottom surface of the first stopper 271 and the top surface of the first stopper 254. The pressing depth of the pressing cap 27 is the shallowest, and the spray pressure is relatively low.

[0047] When the pressing cap 27 is rotated to the second rotation position, as shown in FIG. Figure 5 As shown, the second stopper 272 is aligned with the second stopper 255, the first stopper 271 is offset from the first stopper 254, and the third stopper 273 is offset from the third stopper 256. At this point, the pressing cap 27 is in the second position, the pressing depth of the pressing cap 27 is the distance between the bottom surface of the second stopper 272 and the top surface of the second stopper 255, and the spray pressure is moderate.

[0048] When the pressing cap 27 is rotated to the third rotation position, as shown in FIG. Figure 6 As shown, the third stopper 273 is aligned with the third stopper 256, the first stopper 271 is offset from the first stopper 254, and the second stopper 272 is offset from the second stopper 255. At this point, the pressing cap 27 is in the third position, and the pressing depth of the pressing cap 27 is the distance between the bottom surface of the third stopper 273 and the top surface of the third stopper 256. The pressing depth of the pressing cap 27 is the deepest, and the spray pressure is relatively high.

[0049] Of course, in actual application, there is no limit to the number of limit blocks and stop blocks, and more or fewer gears can be set according to actual needs, thereby achieving multi-gear setting of the spray can 100.
