Description

Technical Field

[0001] This invention relates to the field of solenoid valve technology, and in particular to a bottle solenoid valve. Background Technology

[0002] Currently, essential oil solenoid valves typically introduce air through conduits or vents. The disadvantages are that essential oils can easily cause blockages or leaks in the conduits, and dust can easily accumulate at the vents, leading to blockages. Therefore, all existing air intake methods for essential oil solenoid valves have drawbacks and the risk of blockage. Summary of the Invention

[0003] In view of this, it is necessary to provide a bottle solenoid valve that does not accumulate dust or pose a risk of clogging.

[0004] A bottle solenoid valve includes: a bottle body having a first end and a second end disposed opposite to each other, and the bottle body having a bottle cavity inside, the first end having a first opening communicating with the bottle cavity, and the second end having a second opening communicating with the bottle cavity; a valve body assembly having a valve cavity, a channel, and a valve port, one end of the valve body assembly being sealedly installed at the first end of the bottle body, and the channel communicating with the first opening and the valve cavity; a valve core assembly being installed in the valve cavity and movable within the valve cavity for opening / closing the valve port; and a bottle cap including a covering portion and a wrapping portion connected to the covering portion, the covering portion covering the second opening, and the wrapping portion being detachably connected to the second end of the bottle body and surrounding the circumference of the second end of the bottle body; wherein, a vent is provided on the inner sidewall of the wrapping portion, one end of the vent communicating with the bottle cavity, and the other end being disposed towards the valve body assembly and communicating with the atmosphere.

[0005] Understandably, by setting up a ventilator connected to the atmosphere, the pressure inside and outside the bottle is balanced. In particular, this ventilator is hidden on the inner wall of the packaging and faces the valve assembly. This prevents dust from accumulating at the ventilator inlet, and the cover also shields the ventilator, further eliminating the risk of dust accumulation or debris covering the ventilator and causing blockage. The air intake is reliable and stable, and there is no risk of contamination of the product inside the bottle during long-term storage. Furthermore, since there is no risk of dust accumulation or debris covering the ventilator causing blockage, the air intake cross-section can be appropriately increased to ensure rapid and stable air intake.

[0006] In one embodiment, the outer side wall of the second end of the bottle body is provided with a clearance groove and at least one connecting hole connecting the clearance groove and the bottle cavity; when the wrapping part is connected to the bottle body, the inner side wall of the wrapping part and the clearance groove form a ventilation cavity, and the ventilation channel connects to the bottle cavity through the ventilation cavity and the connecting hole.

[0007] Understandably, the clearance groove is used to avoid the threads on the outer wall of the bottle, preventing insufficient airflow space caused by the threaded connection between the bottle cap and the bottle body. The clearance groove can increase the airflow space and avoid the problem of airway blockage caused by too small airflow space.

[0008] In one embodiment, the inner wall of the wrapping part is provided with an internal thread, and the outer wall of the second end of the bottle body is provided with an external thread. The wrapping part is threadedly connected to the bottle body through the internal thread and the external thread. The ventilation channel extends along the axial direction of the internal thread and is arranged on the inner wall of the wrapping part.

[0009] Understandably, the bottle cap and bottle body are connected by threads, which is a simple connection method and facilitates quick disassembly or assembly of the bottle cap. Furthermore, the vent extends along the axis of the internal thread, thus dividing the internal thread to form a passage for ventilation and preventing blockage of the vent when the bottle body and bottle cap are connected by threads.

[0010] In one embodiment, the number of vents is set to multiple, and the multiple vents are arranged at intervals along the circumference of the bottle cap.

[0011] This design increases the ventilation space and improves the ventilation rate, ensuring that the fluid inside the bottle can flow out smoothly.

[0012] In one embodiment, the outer wall of the wrapping portion is provided with an anti-slip structure.

[0013] Understandably, the anti-slip structure increases friction when screwing on the bottle cap, making it easier to tighten or loosen the cap to close the second opening with less force, saving time and effort.

[0014] In one embodiment, the anti-slip structure includes a protrusion on the outer wall of the package portion; or, the anti-slip structure includes a groove formed on the outer wall of the bottle cap.

[0015] Understandably, the anti-slip structure is simple in design, which helps reduce material and labor costs in processing.

[0016] In one embodiment, the cover protrudes to one side of the bottle body and is provided with a flow guide, which is used to guide the fluid flowing through the cover into the bottle body.

[0017] Understandably, by setting up the flow guide, the fluid is effectively prevented from flowing out of the bottle body from the cover and wrapping, thus preventing fluid loss.

[0018] In one embodiment, the valve body assembly includes: a valve body having the valve cavity and the valve port; an attractor having the channel; and one end of the attractor is connected to the valve body, and the other end of the attractor is sealed to a second end of the bottle body; wherein the attractor attracts the valve core assembly to move.

[0019] In one embodiment, the valve core assembly includes: a core iron located within the valve cavity and having a receiving cavity for engaging with the attractor; a sealing member sleeved on the end of the core iron away from the attractor for opening and closing the valve port; and an elastic member mounted on the receiving cavity, with one end of the elastic member extending out of the receiving cavity and abutting against the attractor.

[0020] In one embodiment, the bottle solenoid valve further includes a coil assembly, which is sleeved outside the valve body assembly and connected to the bottle body, for controlling the movement of the valve core assembly.

[0021] In one embodiment, the coil assembly includes: a mounting bracket detachably mounted on the bottle body; and a coil sleeved on the valve body assembly and fixed to the mounting bracket.

[0022] Understandably, the mounting bracket is detachably mounted on the bottle body, so that the bottle body or the mounting bracket and the valve core assembly mounted on the mounting bracket can be replaced individually without replacing the entire bottle, thereby reducing maintenance costs.

[0023] Compared with existing technologies, the bottle solenoid valve connects to the atmosphere through a vent to balance the pressure inside and outside the bottle. In particular, the vent is concealed on the inner wall of the packaging and faces the valve assembly, preventing dust from accumulating at the vent inlet. The cover also shields the vent, further eliminating the risk of dust accumulation or debris blockage. This ensures reliable and stable air intake, and the product inside the bottle is free from contamination during long-term storage. Furthermore, since there is no risk of dust accumulation or debris blockage in the vent, the cross-section of the vent can be appropriately increased to ensure rapid and stable air intake.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that when a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intervening component. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there may be an intervening component.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] Please see Figures 1 to 9 This invention provides a bottle solenoid valve 100, which includes a bottle cap 10, a bottle body 20, a valve body assembly 30, a valve core assembly 40, and a coil assembly 50. The bottle body 20 has a first end and a second end disposed opposite to each other, and has a bottle cavity 23 inside. The first end has a first opening 24 communicating with the bottle cavity 23, and the second end has a second opening 25 communicating with the bottle cavity 23. The valve body assembly 30 has a valve cavity 31, a channel 32, and a valve port 33. One end of the valve body assembly 30 is sealed and mounted on the first end of the bottle body 20. The valve core assembly 40 is installed in the valve cavity 31 and can move within the valve cavity 31 to open / close the valve port 33. The valve body 35 is sleeved on the outside of the valve body 35 and connected to the bottle body 20 to control the movement of the valve core assembly 40. By controlling the movement of the valve core assembly 40, the flow rate of the fluid in the bottle body 20 from the first opening 24 to the valve port 33 can be controlled.

[0039] In particular, the bottle solenoid valve 100 provided in this application has a bottle cap 10 including a covering part 11 and a wrapping part 12 connected to the covering part 11. The covering part 11 covers the second opening 25, and the wrapping part 12 is detachably connected to the second end of the bottle body 20 and surrounds the second end of the bottle body 20 in the circumference. A venting channel 13 is provided on the inner side wall of the wrapping part 12. One end of the venting channel 13 communicates with the bottle cavity 23, and the other end is set towards the valve body assembly 30 and communicates with the atmosphere.

[0040] Understandably, by setting up a ventilator 13 that communicates with the atmosphere, the pressure inside and outside the bottle 20 is balanced. In particular, the ventilator 13 is hidden on the inner wall of the wrapping part 12 and is positioned towards the valve assembly 30. This prevents dust from accumulating at the inlet of the ventilator 13, and the cover part 11 also shields the ventilator 13, further eliminating the risk of dust accumulation or debris covering the ventilator 13 and causing blockage. The air intake is reliable and stable, and there is no risk of contamination of the product inside the bottle 20 during long-term storage. Furthermore, since there is no risk of dust accumulation or debris covering the ventilator 13 causing blockage, the air intake cross-section of the ventilator 13 can be appropriately increased to ensure rapid and stable air intake.

[0041] Furthermore, in the prior art, the vent hole can be understood to be a vent duct 13 located on the side wall of the wrapping part 12.

[0042] The bottle body 20 is used to hold essential oils and other fluids. By setting a vent 13 that is connected to the atmosphere, the pressure inside and outside the bottle body 20 is balanced, so that essential oils and other fluids can flow out smoothly from the first opening 24.

[0043] In one embodiment, see [reference] Figure 10 A flow guide 15 is provided on the side of the cover 11 facing the bottle body 20. The flow guide 15 is used to guide the fluid flowing through the cover 11 into the bottle body 20, thereby effectively preventing the fluid from flowing out of the bottle body 20 from the cover 11 along the wrapping part 12, causing fluid loss.

[0044] For details, please refer to Figure 10 The cover 11 protrudes towards the bottle body 20 to form the flow guide 15, thereby preventing fluid from flowing out along the outer wall of the bottle body 20 along the cover 11. Of course, in other embodiments, the structure and formation of the flow guide are not limited to those described above or shown in the figures.

[0045] See Figure 4 , Figure 6 as well as Figure 7 The outer wall of the second end of the bottle body 20 is provided with a relief groove 26 and at least one connecting hole 27 connecting the relief groove 26 and the bottle cavity 23. When the wrapping part 12 is connected to the bottle body 20, the inner wall of the wrapping part 12 and the relief groove 26 form a ventilation cavity, and the ventilation channel 13 connects to the bottle cavity 23 through the ventilation cavity and the connecting hole 27. It can be understood that the relief groove 26 is used to avoid the threads on the outer wall of the bottle body 20, so as to avoid insufficient airflow space caused by the threaded connection between the bottle cap 10 and the bottle body 20. The relief groove 26 can increase the airflow space and avoid the problem of airway blockage caused by the airflow space being too small.

[0046] Furthermore, in this embodiment, refer to Figure 6 and Figure 9A narrowed portion 28 is formed at one end of the bottle body 20 near the bottle cap 10. The diameter of the narrowed portion 28 is smaller than the diameter of the bottle body 20. This forms the aforementioned clearance groove 26 between the narrowed portion 28 and the covering portion 12 of the bottle cap 10. Thus, the clearance groove 26 is essentially arranged around the circumference of the bottle body 20, which helps increase the airflow area, effectively prevents blockage, and simplifies the narrowed portion machining process, thereby reducing processing costs. Simultaneously, because the diameter of the narrowed portion 28 is smaller than the diameter of the bottle body 20, it acts as a guide during cap assembly, guiding the bottle cap 10 to be placed on the bottle body 20 along the narrowed portion 28, eliminating the need for precise alignment between the bottle cap 10 and the bottle body 20, thus improving assembly efficiency. Of course, in other embodiments, the method of forming the clearance groove 26 is not limited to the above description; it can also be formed directly by machining and milling.

[0047] See Figure 4 , Figure 7 and Figure 8 The inner wall of the wrapping part 12 is provided with an internal thread 121, and the outer wall of the second end of the bottle body 20 is provided with an external thread 21. The wrapping part 12 achieves a threaded connection between the bottle cap 10 and the bottle body 20 through the engagement of the internal thread 121 and the external thread 21. A vent 13 extends along the axial direction of the internal thread 121 and is arranged on the inner wall of the wrapping part 12. In other words, the vent 13 divides the internal thread 121 to form a ventilation channel 32, preventing blockage of the airway when the bottle body 20 and the bottle cap 10 are threadedly connected. In other embodiments, the extension and arrangement of the vent 13 is not limited to what is described above or shown in the figures. For example, the vent 13 can also extend along the spiral of the bottle cap 10.

[0048] In this application, the number of vents 13 is multiple, and the multiple vents 13 are arranged at intervals along the circumference of the bottle cap 10. For details, please refer to... Figure 7 and Figure 8 In this embodiment, two vents 13 are provided, and the two vents 13 are symmetrically arranged about the axis of the bottle body 20 to ensure uniform air intake and exhaust. In other embodiments, three or four vents 13 may also be provided, etc.

[0049] See Figure 7 and Figure 8 The outer wall of the wrapping part 12 is provided with an anti-slip structure 14. When the bottle cap 10 is screwed on, the anti-slip structure 14 can increase the friction, so that the bottle cap 10 can be screwed on to close the second opening 25 or loosened to open the second opening 25 with less force, saving time and effort.

[0050] In this embodiment, please continue to refer to Figure 7 and Figure 8The anti-slip structure 14 includes protrusions on the outer wall of the wrapping portion 12, with multiple protrusions arranged circumferentially along the wrapping portion 12, thereby increasing the friction force when the wrapping portion 12 is twisted around its periphery. Of course, in another embodiment, the structure of the anti-slip structure 14 is not limited to what has been described above or shown in the figures; for example, the anti-slip structure 14 includes a groove formed on the outer wall of the bottle cap 10.

[0051] For the best options, please continue reading. Figure 7 and Figure 8 Multiple protrusions extend along the axis of the bottle body 20 and are set on the outer side wall of the wrapping part 12. When twisting, the twisting force is perpendicular to the protrusions, so that the force can be applied to the bottle cap 10, making it easier and faster to twist open or close the cap.

[0052] See Figures 3 to 5 The valve body assembly 30 includes a valve body 35 and an aspirator 36. The valve body 35 has a valve cavity 31 and a valve port 33. The aspirator 36 has a channel 32. One end of the aspirator 36 is connected to the valve body 35, and the other end of the aspirator 36 is sealed to the first end of the bottle body 20. When the coil assembly 50 is energized, it can drive the valve core assembly 40 to move, thereby controlling the opening and closing of the valve port 33 and controlling the size of the opening and closing of the valve port 33, thereby controlling the flow rate of the valve port 33.

[0053] See Figure 5 The valve body assembly 30 also includes a valve seat 34, on which a valve port 33 is provided, and the end of the valve body 35 away from the attractor 36 is mounted on the valve seat 34.

[0054] See Figure 5 The valve core assembly 40 includes a core iron 42 and an elastic element 43. The core iron 42 is located in the valve cavity 31 and has a receiving cavity 44 for cooperating with the suction element 36. The elastic element 43 is installed on the receiving cavity 44, and one end of the elastic element 43 extends out of the receiving cavity 44 and abuts against the suction element 36.

[0055] Please continue reading. Figure 5 The valve core assembly 40 also includes a seal 41, which is sleeved on the end of the core iron 42 away from the attractor 36 and is used to open and close the valve port 33 as the core iron 42 moves. The seal 41 strengthens the seal at the valve port 33 to prevent fluid from leaking from the valve port 33.

[0056] See Figures 1 to 3 as well as Figure 5 The coil assembly 50 includes a fixing frame 51, which is mounted on the bottle body 20; the coil is sleeved on the valve body assembly 30 and fixed on the fixing frame 51, so as to achieve a stable connection between the coil assembly 50 and the valve core assembly 40 and the bottle body 20.

[0057] Preferably, the mounting bracket 51 is detachably mounted on the bottle body 20, so that the bottle body 20 or the mounting bracket 51 and the valve core assembly 40 mounted on the mounting bracket 51 can be replaced separately without replacing the entire assembly, thereby reducing maintenance costs.

[0058] Please continue reading. Figure 1 as well as Figure 9 The first end of the bottle body 20 is provided with a mounting part 22. The fixing bracket 51 is detachably connected to the mounting part 22 to ensure that the fixing bracket 51 is installed stably and to prevent the fixing bracket 51 and the valve core assembly 40 from detaching from the bottle body 20, which would cause the fluid inside the bottle body 20 to leak.

[0059] In this embodiment, see Figure 9 The mounting part 22 is a protrusion at the first end, which is integrally formed with the bottle body 20. This ensures that the protrusion and the bottle body 20 have a high connection strength, thereby ensuring that the fixing bracket 51 and the valve core assembly 40 can be stably assembled with the bottle body 20.

[0060] In summary, see the following: Figures 1 to 5 The solenoid valve 100 of the bottle body is a normally closed solenoid valve, and the process of opening and closing the valve port 33 is as follows:

[0061] First, the coil is energized to generate an electromagnetic field, which magnetizes the attractor 36. The attractor 36 attracts the core iron 42, causing the core iron 42 to overcome the elastic force of the elastic element 43 and move towards the attractor 36, thereby driving the sealing element 41 to move and open the valve port 33. When it is necessary to close the valve port 33, the coil is de-energized, the attractor 36 loses its magnetic force, the core iron 42 is no longer attracted by the attractor 36, and the elastic restoring force of the elastic element 43 acts on the core iron 42, thereby pushing the core iron 42 towards the valve port 33 and closing the valve port 33. Of course, in other embodiments, the bottle solenoid valve 100 can also be set as a normally open solenoid valve, and the position of the elastic element 43 and the opening and closing process are changed accordingly.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
