DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, the technical aspects of the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application, but it is clear that the described embodiments are only a part of the embodiments of the present application, and are not all of the embodiments. All other embodiments that a person skilled in the art can obtain based on the embodiments of the present application without creative effort fall within the scope of protection of the present application.

[0021] It should be understood that when an element is "disposed on" another element, it may be disposed directly on the other element, or there may be intervening elements. When an element is considered to be "disposed on" another element, it may be disposed directly on the other element, or there may be intervening elements. When an element is considered to be "secured to" another element, it may be secured directly to the other element, or there may be intervening elements.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. Herein, the terms used in the specification of this application are merely for the purpose of describing specific embodiments and are not intended to limit the scope of this application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0023] 1 to 9, the bottle solenoid valve 100 provided in the present application includes a bottle cap 10, a bottle body 20, a valve body assembly 30, a valve core assembly 40, and a coil assembly 50, wherein the bottle body 20 has a first end and a second end opposite to each other, and has a bottle chamber 23 inside the bottle body 20, a first opening 24 communicating with the bottle chamber 23 formed at the first end, and a second opening 25 communicating with the bottle chamber 23 formed at the second end, the valve body assembly 30 has a valve chamber 31, a passage 32, and a valve port 33, one end of the valve body assembly 30 is sealingly attached to the first end of the bottle body 20, and the passage The first opening 24 and the valve chamber 31 are connected by the passage 32, so that the fluid in the bottle chamber 23 can flow from the bottle chamber 23 into the valve chamber 31 through the passage 32. The valve core assembly 40 is mounted in the valve chamber 31 and is movable within the valve chamber 31, and is used to open and close the valve port 33. The coil assembly 50 is fitted to the outside of the valve body 35 and connected to the bottle body 20, and is used to control the movement of the valve core assembly 40. By controlling the movement of the valve core assembly 40, the fluid in the bottle body 20 can flow from the first opening 24 to the valve port 33 and the flow rate of the fluid flowing out of the valve port 33 can be controlled.

[0024] In particular, in the bottle solenoid valve 100 provided in the present application, the bottle cap 10 includes a covering portion 11 and an envelope portion 12 connected to the covering portion 11, the covering portion 11 covers the second opening 25, the envelope portion 12 is detachably connected to the second end of the bottle body 20 and is arranged to surround the second end of the bottle body 20 in the circumferential direction, an air passage 13 is drilled in the inner wall of the envelope portion 12, one end of the air passage 13 is connected to the bottle chamber 23, and the other end is arranged toward the valve body assembly 30 and is connected to the atmosphere.

[0025] The provision of an air vent passage 13 communicating with the atmosphere is used to equalize the pressure inside and outside the bottle body 20. In particular, the air vent passage 13 is hidden in the inner wall of the wrapper part 12 and faces the valve body assembly 30. In this way, dust cannot accumulate at the entrance of the air vent passage 13, and the covering part 11 has a blocking effect on the air vent passage 13, further eliminating the problem of the air vent passage 13 being clogged by dust accumulation or impurity coating. Air intake is reliable and stable, and there is no risk of impurity contamination when storing products in the bottle body 20 for long periods of time. Furthermore, because there is no risk of the air vent passage 13 being clogged by dust accumulation or impurity coating, the ventilation cross-section of the air vent passage 13 can be appropriately increased to ensure rapid and stable air intake.

[0026] Furthermore, the ventilation passage 13 is provided in the side wall of the envelope 12, Here, the bottle body 20 is used to contain fluids such as essential oils, and by providing an air passage 13 that is connected to the atmosphere, the pressure inside and outside the bottle body 20 is equalized, allowing the fluids such as essential oils to flow out smoothly from the first opening 24.

[0027] In one embodiment, referring to FIG. 10, a flow guide portion 15 is provided protruding from the side of the covering portion 11 facing the bottle body 20 to guide the fluid flowing through the covering portion 11 into the bottle body 20, thereby effectively preventing the fluid from flowing out of the covering portion 11 along the wrapping portion 12 to the outside of the bottle body 20 and causing fluid loss.

[0028] 10, the covering portion 11 protrudes toward the bottle body 20 to form a flow guide portion 15, thereby preventing fluid from flowing out of the outer wall of the bottle body 20 along the covering portion 11. Of course, in other embodiments, the structure and formation of the flow guide portion are not limited to those described above or shown in the drawings.

[0029] 4, 6 and 7, the outer wall of the second end of the bottle body 20 is provided with an avoidance groove 26 and at least one communication hole 27 connecting the avoidance groove 26 and the bottle chamber 23. When the wrapper 12 is connected to the bottle body 20, an air vent chamber is formed between the inner wall of the wrapper 12 and the avoidance groove 26, and the air vent channel 13 is connected to the bottle chamber 23 via the air vent chamber and the communication hole 27. The avoidance groove 26 is used to avoid the threads on the outer wall of the bottle body 20, and prevents insufficient airflow space caused by the screwing of the bottle cap 10 and the bottle body 20. The avoidance groove 26 increases the airflow space, preventing the airflow channel from being clogged due to an insufficient airflow space.

[0030] 6 and 9, in this embodiment, a tapered portion 28 is formed at one end of the bottle body 20 adjacent to the bottle cap 10. Because the diameter of the tapered portion 28 is smaller than that of the bottle body 20, the above-mentioned avoidance groove 26 is formed between the tapered portion 28 and the wrapping portion 12 of the bottle cap 10. This is equivalent to the avoidance groove 26 being provided around the entire circumference of the bottle body 20, which is advantageous for increasing the airflow area, effectively preventing clogging, and reducing processing costs because the tapering process is relatively simple. At the same time, because the diameter of the tapered portion 28 is smaller than that of the bottle body 20, the tapered portion 28 acts as a guide during assembling the bottle cap, guiding the bottle cap 10 so that it is placed over the bottle body 20 along the tapered portion 28. This eliminates the need to precisely align the bottle cap 10 and the bottle body 20, improving assembly efficiency. Of course, in other embodiments, the form of forming the avoidance groove 26 is not limited to the above, and the avoidance groove 26 may be directly formed by milling in a mechanical process.

[0031] 4, 7, and 8, an internal thread 121 is provided on the inner wall of the envelope part 12, and an external thread 21 is provided on the outer wall of the second end of the bottle body 20, and the envelope part 12 realizes the screwing of the bottle cap 10 and the bottle body 20 by the engagement of the internal thread 121 and the external thread 21, wherein the air vent 13 extends along the axial direction of the internal thread 121 and is disposed on the inner wall of the envelope part 12, in other words, the air vent 13 divides the internal thread 121 to form a ventilated passage 32, which prevents the air vent 13 from being clogged when the bottle body 20 and the bottle cap 10 are screwed together. In other embodiments, the form of the extending arrangement of the air vent 13 is not limited to that described above or shown in the drawings, and for example, the air vent 13 may be provided to extend along the spiral of the bottle cap 10.

[0032] In the present application, there are multiple ventilation channels 13, and the multiple ventilation channels 13 are spaced apart along the circumferential direction of the bottle cap 10. Specifically, referring to Figures 7 and 8, in this embodiment, two ventilation channels 13 are provided, and the two ventilation channels 13 are provided symmetrically with respect to the axis of the bottle body 20 to ensure uniform intake and exhaust. In other embodiments, three or four ventilation channels 13 may be provided.

[0033] 7 and 8, an anti-slip structure 14 is provided on the outer wall of the wrapper 12. When screwing on the bottle cap 10, the anti-slip structure 14 increases the frictional force, allowing less force to be used to tighten the bottle cap 10 to close the second opening 25 or loosen it to open the second opening 25, thereby reducing the time and effort required.

[0034] 7 and 8, in this embodiment, the anti-slip structure 14 includes protrusions protruding from the outer wall of the wrapper 12, and the protrusions are arranged along the circumferential direction of the wrapper 12, thereby increasing the frictional force when screwing in the circumferential side of the wrapper 12. Of course, in other embodiments, the structure of the anti-slip structure 14 is not limited to that described above or shown in the drawings, and for example, the anti-slip structure 14 includes a groove drilled in the outer wall of the bottle cap 10.

[0035] Optionally, still referring to Figures 7 and 8, a plurality of protrusions are provided extending on the outer wall of the wrapper portion 12 along the axis of the bottle body 20, and the screwing force when screwing is perpendicular to the protrusions, so that the entire force can be applied to the bottle cap 10, thereby making it easier and faster to screw on and open the cap.

[0036] 3 to 5, the valve body assembly 30 includes a valve body 35 having a valve chamber 31 and a valve port 33, and a suction element 36 having a passage 32 formed therein, one end connected to the valve body 35 and the other end sealingly connected to a first end of the bottle body 20. When energized, the coil assembly 50 can move the valve core assembly 40 in conjunction with the valve body 35, thereby controlling the opening and closing of the valve port 33 and the magnitude of the opening and closing of the valve port 33, and thereby controlling the flow rate of the valve port 33.

[0037] Referring to FIG. 5, the valve body assembly 30 further includes a valve seat 34 having a valve port 33 formed therein, and one end of the valve body 35 remote from the suction element 36 is attached to the valve seat 34 .

[0038] Referring to Figure 5, the valve core assembly 40 includes a core 42 and an elastic member 43, wherein the core 42 is located within the valve chamber 31 and has a receiving chamber 44 formed therein for engaging with the suction element 36, and the elastic member 43 is attached to the receiving chamber 44 and has one end protruding from the receiving chamber 44 to abut against the suction element 36.

[0039] Continuing to refer to Figure 5, the valve core assembly 40 further includes a sealing member 41 fitted to one end of the core wire 42 away from the suction element 36 and used to open and close the valve orifice 33 in accordance with the movement of the core wire 42, and the sealing member 41 strengthens the seal at the valve orifice 33 to prevent fluid from leaking from the valve orifice 33.

[0040] 1 to 3 and 5, the coil assembly 50 includes a fixed holder 51 attached to the bottle body 20, and the coil 52 is fitted into the valve body assembly 30 and fixed to the fixed holder 51 to ensure that the coil assembly 50 and the valve core assembly 40 are stably connected to the bottle body 20.

[0041] Optionally, the fixed holder 51 is removably attached to the bottle body 20, which makes it easy to replace the bottle body 20 alone or to replace the fixed holder 51 and the valve core assembly 40 attached to the fixed holder 51, without the need to replace everything, further reducing maintenance costs.

[0042] Continuing to refer to Figures 1 and 9, an attachment part 22 is provided at the first end of the bottle body 20, and the fixed holder 51 is removably connected to the attachment part 22 to ensure stable attachment of the fixed holder 51 and prevent the fixed holder 51 and the valve core assembly 40 from detaching from the bottle body 20 and causing fluid in the bottle body 20 to leak.

[0043] Here, in this embodiment, referring to FIG. 9, the mounting portion 22 is a boss provided at the first end, and the boss and the bottle body 20 are integrally molded, thus ensuring that the boss and the bottle body 20 have a relatively high connection strength, and further ensuring that the fixed holder 51 and the valve core assembly 40 can be stably assembled to the bottle body 20.

[0044] As described above, referring to FIGS. 1 to 5, the bottle solenoid valve 100 is a normally closed solenoid valve, and the process for opening and closing the valve port 33 is as follows. First, the coil 52 is energized to generate an electromagnetic field, which magnetizes the attractor 36, causing the attractor 36 to attract the mandrel 42, causing the mandrel 42 to overcome the elastic force of the elastic member 43 and move toward the attractor 36, thereby moving the sealing member 41 in conjunction to open the valve port 33. When it is necessary to close the valve port 33, the coil 52 is turned off, the attractor 36 loses its magnetic force, the mandrel 42 is no longer attracted to the attractor 36, and the elastic restoring force of the elastic member 43 acts on the mandrel 42, causing it to move toward the valve port 33 and close the valve port 33. Of course, in other embodiments, the bottle solenoid valve 100 may be a normally open solenoid valve, and the position of the corresponding elastic member 43 and the valve opening and closing flows are changed accordingly.

[0045] The technical features of the above embodiments may be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features are not contradictory, they should all be considered within the scope of the present specification.

[0046] It should be understood by those skilled in the art that the above embodiments are merely used to explain the present application, and are not intended to limit the present application; any appropriate modifications and variations made by the above embodiments within the essential spirit of the present application fall within the scope of the protection claimed by the present application.
