Description

Technical Field

[0001] This application relates to the field of spray technology, and in particular to a spray device. Background Technology

[0002] Aromatherapy spray devices are products designed to improve and beautify indoor air quality by spraying liquids containing fragrances or essential oils. They not only purify the air but also enhance mood and create a pleasant atmosphere. The ingredients in aromatherapy sprays can include natural components such as tea tree oil and lavender oil, which have antibacterial and air-purifying effects. Furthermore, different scents are closely linked to human emotions; for example, citrus scents can be invigorating, while lavender scents help relax the mind and body. However, traditional spray devices have a disposable liquid reservoir. To prevent clogging of the atomizing mechanism, it is also housed within the reservoir. Once the liquid in the reservoir is depleted, both the reservoir and the atomizing mechanism are discarded. To allow the aerosol generated by the atomizing mechanism to flow out of the reservoir, a channel connecting it to the outside is necessary. Therefore, when the spray device is tilted, the liquid inside will easily flow out through this channel under gravity, resulting in leakage. Summary of the Invention

[0003] One of the technical problems addressed by this application is how to prevent liquid leakage from spray devices.

[0004] A spraying device, comprising:

[0005] The liquid storage mechanism is equipped with a liquid storage chamber for storing liquid;

[0006] An atomizing mechanism is disposed within the liquid storage chamber to atomize the liquid;

[0007] The sealing mechanism includes a spray hole and a connecting hole, wherein the connecting hole communicates with the liquid storage chamber, and the spray hole communicates with the outside environment; and

[0008] A leak-proof mechanism includes a leak-proof component, a first sealing element, and a second sealing element. The leak-proof component is disposed within the sealing mechanism and has a first channel and a second channel that are interconnected. The first channel is connected to the connecting hole, and the second channel is connected to the spray hole. The first sealing element is movably disposed within the first channel to close or open the first channel, and the second sealing element is movably disposed within the second channel to close or open the second channel. The first channel and the second channel can be opened simultaneously, and at least one of the first channel and the second channel can be closed.

[0009] In one embodiment, the leak-proof assembly includes a first leak-proof component and a second leak-proof component. The first leak-proof component is located within the capping mechanism and has a first receiving cavity and a first through hole that are interconnected and configured to form the first channel. The first sealing component is movably disposed within the first receiving cavity. The second leak-proof component has a second receiving cavity and a second through hole that are interconnected and configured to form the second channel. The second sealing component is movably disposed within the second receiving cavity. The first leak-proof component is located within the second receiving cavity, the first receiving cavity is connected to the connecting hole, the first through hole is connected to the second receiving cavity, and the second through hole is connected to the spray hole. The first sealing component can block or open the first through hole, and the second sealing component can block or open the second through hole.

[0010] In one embodiment, the first sealing member is spherical and can move closer to or further away from the first through hole within the first accommodating cavity under the action of gravity; the second sealing member is spherical and can move closer to or further away from the second through hole within the second accommodating cavity under the action of gravity.

[0011] In one embodiment, the first receiving cavity includes a first limiting channel that slides with the first sealing member and extends to the first through hole, with the distance from the first limiting channel away from the first through hole to the end near the first through hole increasing; the second receiving cavity includes a second limiting channel that slides with the second sealing member and extends to the second through hole, with the distance from the second limiting channel away from the second through hole to the end near the second through hole increasing; a plane passing through the centerline of the liquid storage cavity and simultaneously cutting the first limiting channel and the second limiting channel is used as a reference plane, with the end of the first limiting channel near the first through hole and the end of the second limiting channel away from the second through hole located on the same side of the reference plane.

[0012] In one embodiment, the extension directions of the first limiting channel and the second limiting channel are set at an angle, and the angle between the extension directions of the first limiting channel and the second limiting channel and the center line of the liquid storage cavity is equal. For the outer side of the main unit that is matched with the spray device, the outer side extends along the axial direction of the liquid storage mechanism and contacts the carrier when tilted. The plane where the first limiting channel and the second limiting channel are located extends along the axial direction of the liquid storage mechanism and is set at an angle to the outer side.

[0013] In one embodiment, the first leak-proof component includes a first sleeve and two first limiting plates. The first sleeve forms the first receiving cavity and abuts against the capping mechanism. The first through hole is disposed in the first sleeve. The two first limiting plates are arranged radially spaced along the liquid storage cavity. The capping mechanism includes two second limiting plates arranged radially spaced along the liquid storage cavity and located within the first receiving cavity. The space between the first limiting plates and the second limiting plates in the axial direction of the liquid storage cavity forms the first limiting channel.

[0014] In one embodiment, the second leak-proof component includes a second sleeve and two third limiting plates. The second sleeve forms the second receiving cavity and is connected to the capping mechanism. The second through hole is disposed in the second sleeve. The two third limiting plates are arranged radially spaced along the liquid storage cavity. The first leak-proof component includes two fourth limiting plates arranged radially spaced along the liquid storage cavity and located within the second receiving cavity. The space between the third limiting plates and the fourth limiting plates in the axial direction of the liquid storage cavity forms the second limiting channel.

[0015] In one embodiment, the liquid storage mechanism includes a liquid storage bottle and a sealing cap, the liquid storage cavity is disposed in the liquid storage bottle, the sealing cap is non-detachably connected to the liquid storage bottle and seals the liquid storage cavity, and the atomizing mechanism is connected to the sealing cap.

[0016] In one embodiment, the liquid storage mechanism further includes a straw, and the atomizing mechanism has a gas channel and a liquid channel that are both connected to the liquid storage chamber. The straw is fixedly connected to the atomizing mechanism and the lumen of the straw is connected to the liquid channel. The liquid channel has an atomizing port located near the gas channel.

[0017] In one embodiment, the sealing mechanism includes a base and a cover, the base and the cover forming a buffer cavity, the spray hole being disposed on the cover, the base having an air inlet and a flow guide, a connecting hole being disposed on the base, the air inlet connecting to the buffer cavity, and the leak-proof mechanism being located within the buffer cavity and fixedly connected to the base; the base is connected to the liquid storage mechanism and forms a gas guiding cavity with the liquid storage mechanism, the flow guide connecting the gas guiding cavity and the buffer cavity, and the liquid storage mechanism having an air outlet connecting to the gas guiding cavity, the air outlet being used to supply gas to the atomizing mechanism.

[0018] In one embodiment, the base includes a first substrate, a second substrate, an outer sleeve, an inner sleeve, and a boss. The outer sleeve is connected to the periphery of the first substrate, the second substrate is located inside the outer sleeve and spaced apart from the first substrate, the inner sleeve is connected between the first substrate and the second substrate and is located inside the outer sleeve, the boss protrudes from the second substrate and extends into the inner sleeve, the boss is inserted into the liquid storage mechanism and has the communicating hole; the cover, the outer sleeve, the first substrate, the inner sleeve, and the second substrate form the buffer cavity, the air inlet is located in the outer sleeve, the flow guide hole is located in the second substrate, and the air guide cavity is formed between the second substrate, the inner sleeve, and the liquid storage mechanism.

[0019] In one embodiment, the second substrate and the inner sleeve form a first cavity and a second cavity. The diameter of the first cavity is larger than the diameter of the second cavity. The first cavity is closer to the liquid storage cavity than the second cavity. The connection between the first cavity and the second cavity has a stepped surface spaced apart from the second substrate. The liquid storage mechanism cooperates with the first cavity and abuts against the stepped surface. The liquid storage mechanism also seals the second cavity to form the gas guide cavity.

[0020] In one embodiment, the cover includes a cover plate and a protrusion. The protrusion protrudes from the cover plate and extends into the buffer cavity. The protrusion abuts against the leak-proof mechanism. The spray hole is disposed on the protrusion. The protrusion also has a reinforcing hole communicating with the spray hole and the buffer cavity. The diameter of the reinforcing hole is smaller than the diameter of the spray hole.

[0021] In one embodiment, the protrusion has an abutting surface that abuts against the leak-proof mechanism, and the reinforcing hole is disposed on the abutting surface.

[0022] One technical effect of an embodiment of this application is that when the spraying device is in operation, the first channel and the second channel can be opened simultaneously, ensuring the normal operation of the spraying device. When the spraying device is in a tilted state, at least one of the first channel and the second channel can be closed, preventing liquid in the storage chamber from flowing out through the first and second channels and causing liquid leakage. Therefore, the leak-proof mechanism can effectively prevent liquid leakage when the spraying device is in a tilted state. The atomizing mechanism is located in the storage chamber and needs to be supplied with high-pressure gas to atomize the liquid. Therefore, there is a high air pressure in the storage chamber. When the spraying device is in a tilted state, the high-pressure gas still enters the storage chamber. Driven by the air pressure, the leak-proof mechanism can more reliably seal the first and second channels, thereby further improving the leak-proof effect. Attached Figure Description

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] Referring to Figure 10, an embodiment of this application provides a spraying device 10 including a liquid storage mechanism 100, an atomizing mechanism 200, a capping mechanism 300, and a leak-proof mechanism 400. The capping mechanism 300 is disposed on the liquid storage mechanism 100, and the atomizing mechanism 200 and the leak-proof mechanism 400 are both connected to the capping mechanism 300.

[0042] In some embodiments, the liquid storage mechanism 100 includes a liquid storage bottle 110, a sealing cap 120, and a straw 140. A liquid storage chamber 150 is disposed in the liquid storage bottle 110, and the sealing cap 120 is fixedly connected to the liquid storage bottle 110 in a non-removable manner. The liquid storage chamber 150 is used to contain liquid. When the liquid in the liquid storage chamber 150 is consumed, since the sealing cap 120 and the liquid storage bottle 110 are non-removable, liquid cannot be added to the liquid storage chamber 150, making the liquid storage mechanism 100 and the entire spray device 10 disposable. A vent 121 is provided on the sealing cap 120. The atomizing mechanism 200 is fixedly connected to the sealing cap 120. The atomizing mechanism 200 has a gas channel 210 and a liquid channel 220. The gas channel 210 is interconnected with the vent 121. One end of the straw 140 can be inserted into the liquid channel 220, so that the straw 140 is fixedly connected to the atomizing mechanism 200 and the lumen of the straw 140 is interconnected with the liquid channel 220. The lower end of the straw 140 is located near the bottom of the liquid storage bottle 110. The outlet of the liquid channel 220 is the atomizing port 221, which is located near one end of the gas channel 210. During operation, high-pressure gas can be received in the vent 121, and the high-pressure gas will be ejected through the gas channel 210 and sprayed towards the atomizing port 221. This creates a Venturi effect, resulting in a relatively low pressure at the atomizing port 221, forming a negative pressure. Under this negative pressure, the liquid in the storage chamber 150 flows through the suction tube 140 and the liquid channel 220 to the atomizing port 221 at a certain speed. Simultaneously, high-pressure gas is ejected from the gas channel 210, forming a high-speed gas. This high-speed gas shears and breaks up the liquid at the atomizing port 221, atomizing it into an aerosol. This aerosol can then be discharged to the outside, thus achieving the liquid atomization function of the spray device 10.

[0043] Since high-pressure gas enters the liquid storage chamber 150 directly from the gas channel 210, the pressure in the liquid storage chamber 150 is increased, allowing more liquid to reach the atomizing port 221 for atomization per unit time, thereby increasing the atomization volume of the liquid. Simultaneously, it effectively prevents negative pressure in the liquid storage chamber 150 due to liquid consumption, ensuring the smooth delivery of liquid from the liquid storage chamber 150 to the spraying mechanism. It is understood that, since the spraying mechanism is housed within the liquid storage chamber 150, during the injection of liquid into the liquid storage chamber 150, the liquid level in the liquid storage chamber 150 should not reach the atomizing mechanism 200 to prevent the liquid from flooding or blocking the atomizing port 221 and the outlet of the gas channel 210, ensuring that the atomizing mechanism 200 can properly perform its atomization function.

[0044] Since the sealing cap 120 and the liquid storage bottle 110 are not removable, on the one hand, it can prevent the addition of non-compliant liquids to the liquid storage bottle 110, thus avoiding the generation of aerosols that are harmful to the human body after the non-compliant liquids are atomized, and also preventing non-compliant liquids from clogging the atomizing mechanism 200 during operation. On the other hand, it can make the liquid storage mechanism 100 and the entire spray device 10 disposable, preventing the atomizing mechanism 200 from becoming blocked due to long-term use, and effectively ensuring that the liquid channel 220 of the atomizing mechanism 200 remains unobstructed until the spray device 10 is discarded.

[0045] In some embodiments, the sealing mechanism 300 includes a base 310 and a cover 320. The base 310 includes a first substrate 311, a second substrate 312, an outer sleeve 313, an inner sleeve 314, and a boss 315. The first substrate 311 may be generally annular. The outer sleeve 313 is connected to the outer periphery of the first substrate 311. One end of the inner sleeve 314 is connected to the inner periphery of the first substrate 311, such that the inner sleeve 314 is located inside the outer sleeve 313. Therefore, the outer sleeve 313 is arranged around the inner sleeve 314. The second substrate 312 is located inside the outer sleeve 313, and the other end of the second substrate 312 is connected to the inner sleeve 314, such that the inner sleeve 314 is connected between the first substrate 311 and the second substrate 312. The boss 315 protrudes from the second substrate 312, such that the boss 315 can extend into the inner sleeve 314. The cover 320, outer sleeve 313, first substrate 311, inner cylinder, and second substrate 312 together form a buffer cavity 3132. A leak-proof mechanism 400 is located in the buffer cavity 3132 and fixedly connected to the second substrate 312; for example, the leak-proof mechanism 400 and the second substrate 312 can be bolted together. An air inlet 3131 is provided on the outer sleeve 313, communicating with the buffer cavity 3132. The air pump 20 can supply high-pressure gas to the buffer cavity 3132 through the air inlet 3131. Multiple flow guide holes 3121 are provided on the second substrate 312, spaced circumferentially along the second substrate 312. A connecting hole 3151 is provided on the boss 315, which can be inserted into the sealing cover 120 of the liquid storage mechanism 100, thus connecting the liquid storage mechanism 100 with the sealing cover mechanism 300. The connecting hole 3151 connects to the liquid storage chamber 150.

[0046] In some embodiments, the second substrate 312 and the inner sleeve 314 form a first cavity 3141 and a second cavity 3142. The diameter of the first cavity 3141 is larger than the diameter of the second cavity 3142. The first cavity 3141 is closer to the liquid storage cavity 150 than the second cavity 3142. The first cavity 3141 and the second cavity 3142 can be coaxially arranged, so that the inner sleeve 314 has a stepped surface 3144 at the connection between the first cavity 3141 and the second cavity 3142. Obviously, the stepped surface 3144 is spaced apart from the second substrate 312. During the installation of the liquid storage mechanism 100 and the capping mechanism 300, when the boss 315 is inserted into the sealing cap 120 of the liquid storage mechanism 100, the liquid storage bottle 110 will be inserted into the first cavity 3141, so that the liquid storage bottle 110 abuts against the stepped surface 3144, thus effectively limiting the liquid storage bottle 110. After the liquid storage bottle 110 is inserted into the first chamber 3141, it seals the second chamber 3142, thus forming a gas guiding chamber 3143. The gas guiding chamber 3143 is interconnected with the flow guide hole 3121 and the air outlet 121. During operation, the high-pressure gas generated by the air pump 20 passes sequentially through the air inlet 3131, the buffer chamber 3132, the flow guide hole 3121, the gas guiding chamber 3143, and the air outlet 121 into the gas channel 210 of the atomizing mechanism 200, and finally the gas is sprayed from the gas channel 210 to the atomizing port 221, thereby realizing the atomization of the liquid.

[0047] In some embodiments, the cover 320 includes a cover plate 321 and a protrusion 322. The cover plate 321 is connected to the outer sleeve 313, and the cover plate 321 and the base 310 form a buffer cavity 3132. The protrusion 322 protrudes from the cover plate 321 and extends into the buffer cavity 3132. The protrusion 322 abuts against the leak-proof mechanism 400. A spray hole 3221 is provided on the protrusion 322, which communicates with the outside. During operation, the aerosol generated by atomization in the liquid storage cavity 150 can enter the interior of the leak-proof mechanism 400 through the communication hole 3151 and be sprayed out to the outside through the spray hole 3221. It can be understood that the high-pressure gas in the liquid storage cavity 150 carries the aerosol and is discharged to the outside through the communication hole 3151 and the interior of the leak-proof mechanism 400 through the spray hole 3221, avoiding excessively high gas pressure in the liquid storage cavity 150 due to the inability to expel gas in time.

[0048] In some embodiments, the protrusion 322 has an abutment surface 3222, which abuts against the leak-proof mechanism 400. A reinforcing hole 3223 is provided on the abutment surface 3222, that is, the reinforcing hole 3223 is formed by a portion of the abutment surface 3222 being recessed. The diameter of the reinforcing hole 3223 is smaller than the diameter of the spray hole 3221. The reinforcing hole 3223 connects the spray hole 3221 and the buffer chamber 3132. The number of reinforcing holes 3223 can be one or more. The extending direction of the reinforcing hole 3223 can be set at a certain angle with the radial direction of the spray hole 3221. When the abutment surface 3222 abuts against the leak-proof mechanism 400, the leak-proof mechanism 400 can play a certain sealing role for the reinforcing hole 3223. During the process of aerosol being discharged from the spray hole 3221 to the outside, since the reinforcing hole 3223 connects the spray hole 3221 and the buffer chamber 3132, the high-pressure gas in the buffer chamber 3132 can enter the spray hole 3221 through the reinforcing hole 3223, thereby forming a vortex in the spray hole 3221, that is, generating the Bernoulli effect and the vortex effect. Under the combined effect of the Bernoulli effect and the vortex effect, the aerosol is ejected at a greater speed and pressure, which on the one hand increases the radiation range of the aerosol, and on the other hand reduces the formation of deposited liquid in the spray device 10.

[0049] In other embodiments, the base 310 and the cover 320 may have other modified structures, as long as the air inlet 3131 can supply high-pressure gas to the air outlet 121 and the gas passage 210. The reinforcing hole 3223 may also be omitted.

[0050] In some embodiments, the cover plate 321 can be approximately a rectangular plate, and the cross-section of the outer sleeve 313 can also be approximately rectangular, such that the length direction of the cover plate 321 and the length direction of the outer sleeve 313 are set at an acute angle, and the width direction of the cover plate 321 and the width direction of the outer sleeve 313 are also set at an acute angle. For example, the length direction of the cover plate 321 is at 45° to the length of the outer sleeve 313, and the width direction of the cover plate 321 is at 45° to the width direction of the outer sleeve 313.

[0051] In some embodiments, the leak-proof mechanism 400 includes a leak-proof component 403, a first sealing member 401, and a second sealing member 402. The leak-proof component 403 is disposed within the buffer cavity 3132 of the capping mechanism 300. The leak-proof component 403 has a first channel 4031 and a second channel 4032, which are interconnected. The first channel 4031 communicates with a connecting hole 3151, and the second channel 4032 communicates with a spray hole 3221. The first sealing member 401 is movably disposed within the first channel 4031 and can close or open the first channel 4031. The second sealing member 402 is movably disposed within the second channel 4032 and can close or open the second channel 4032. The first channel 4031 and the second channel 4032 can be opened simultaneously, and at least one of the first channel 4031 and the second channel 4032 can be closed. For example, when the spray device 10 is in operation, the first channel 4031 and the second channel 4032 can be simultaneously opened and interconnected, allowing the liquid storage chamber 150 to be interconnected with the spray hole 3221 through the connecting hole 3151, the first channel 4031, and the second channel 4032 in sequence, so that the aerosol produced by atomization in the liquid storage chamber 150 can be discharged through the spray hole 3221. For example, when the spray device 10 is in the tilted state, at least one of the first channel 4031 and the second channel 4032 can be closed, so that the liquid storage chamber 150 cannot be connected to the spray hole 3221 through the first channel 4031 and the second channel 4032. Therefore, the liquid in the liquid storage chamber 150 cannot leak out of the spray device 10 through the connecting hole 3151, the first channel 4031, the second channel 4032, and the spray hole 3221, thus effectively preventing liquid leakage from the spray device 10.

[0052] In some embodiments, the leak-proof assembly 403 includes a first leak-proof component 410 and a second leak-proof component 420. The first leak-proof component 410 includes a first sleeve 411 and two first limiting plates 412. The first sleeve 411 forms a first receiving cavity 4111. The two first limiting plates 412 can be arranged radially at intervals on the first sleeve 411 along the liquid storage cavity 150. The first limiting plates 412 are located inside the first receiving cavity 4111. The base 310 may also include two second limiting plates 316. The second limiting plates 316 are located inside the first receiving cavity 4111. The two second limiting plates 316 can be arranged radially at intervals on the second substrate 312 along the liquid storage cavity 150. The first sleeve 411 can abut against the second substrate 312. It can also be fixedly connected to the second substrate 312. The first sleeve 411 is provided with a first through hole 4112. The first accommodating cavity 4111 and the first through hole 4112 are configured as a first channel 4031, which can be understood as the first channel 4031 including the first accommodating cavity 4111 and the first through hole 4112. The space between the first limiting plate 412 and the second limiting plate 316 in the axial direction of the liquid storage cavity 150 forms a first limiting channel 4121. Obviously, the first limiting channel 4121 is part of the first accommodating cavity 4111. It can be understood that the first accommodating cavity 4111 includes the first limiting channel 4121. One end of the first limiting channel 4121 extends to the position where the first through hole 4112 is located. The first sealing member 401 slides with the first limiting channel 4121. When the first sealing member 401 slides to the end of the first limiting channel 4121 near the first through hole 4112, the first sealing member 401 will block the first through hole 4112, preventing the first receiving cavity 4111 from communicating with the first through hole 4112, thereby closing the entire first channel 4031. When the first sealing member 401 slides to the end of the first limiting channel 4121 away from the first through hole 4112, the first sealing member 401 will open the first through hole 4112, allowing the first receiving cavity 4111 to communicate with the first through hole 4112, thereby opening the entire first channel 4031. For ease of description, the end of the first limiting channel 4121 near the first through hole 4112 can be referred to as the sealed end, and the end of the first limiting channel 4121 away from the first through hole 4112 can be referred to as the open end.

[0053] In some embodiments, the second leak-proof component 420 includes a second sleeve 421 and two third limiting plates 422. The second sleeve 421 forms a second receiving cavity 4211 and can be bolted to the second base plate 312. The two second limiting plates 316 can be radially spaced on the second sleeve 421 along the liquid storage cavity 150 and are located within the second receiving cavity 4211. The first leak-proof component 410 may also include two fourth limiting plates 413. Since the entire first leak-proof component 410 is located within the second receiving cavity 4211, the fourth limiting plates 413 are also located within the second receiving cavity 4211. The two fourth limiting plates 413 can be radially spaced on the first sleeve 411 along the liquid storage cavity 150. When the first sealing component 401 closes the first through hole 4112, the first receiving cavity 4111 and the second receiving cavity 4211 cannot communicate with each other. The second sleeve 421 is provided with a second through hole 4212. The second accommodating cavity 4211 and the second through hole 4212 are configured as a second channel 4032, which can be understood as the second channel 4032 including the second accommodating cavity 4211 and the second through hole 4212. The space between the third limiting plate 422 and the fourth limiting plate 413 in the axial direction of the liquid storage cavity 150 forms a second limiting channel 4221. Obviously, the second limiting channel 4221 is part of the second accommodating cavity 4211, which can be understood as the second accommodating cavity 4211 including the second limiting channel 4221. One end of the second limiting channel 4221 extends to the position where the second through hole 4212 is located, and the second sealing member 402 slides with the second limiting channel 4221. When the second sealing member 402 slides to the end of the second limiting channel 4221 near the second through hole 4212, the second sealing member 402 will block the second through hole 4212, preventing the second receiving cavity 4211 from communicating with the second through hole 4212, thereby closing the entire second channel 4032. When the second sealing member 402 slides to the end of the second limiting channel 4221 away from the second through hole 4212, the second sealing member 402 will open the second through hole 4212, allowing the second receiving cavity 4211 to communicate with the second through hole 4212, thereby opening the entire second channel 4032. For ease of description, the end of the second limiting channel 4221 near the second through hole 4212 can be referred to as the sealed end, and the end of the second limiting channel 4221 away from the second through hole 4212 can be referred to as the open end.

[0054] The second through hole 4212 and the spray hole 3221 are interconnected. When the second sealing member 402 opens the second through hole 4212, the second channel 4032 is interconnected with the spray hole 3221. When the second sealing member 402 closes the second through hole 4212, the second channel 4032 is not interconnected with the spray hole 3221. Therefore, when the first sealing member 401 and the second sealing member 402 simultaneously open the first channel 4031 and the second channel 4032, respectively, the aerosol in the liquid storage chamber 150 can sequentially pass through the connecting hole 3151, the first accommodating cavity 4111, the first through hole 4112, the second accommodating cavity 4211, the second through hole 4212, and the spray hole 3221, causing the aerosol to be sprayed out from the spray hole 3221. Obviously, when at least one of the first channel 4031 and the second channel 4032 is blocked, the aerosol in the liquid chamber cannot be sprayed out through the spray hole 3221.

[0055] In some embodiments, the first sealing member 401 is spherical, and its density may be greater than the density of the liquid in the storage cavity 150. The first sealing member 401 can move closer to or further away from the first through hole 4112 within the first limiting channel 4121 under the influence of gravity. The second sealing member 402 is spherical, and its density may be greater than the density of the liquid in the storage cavity 150. The second sealing member 402 can move closer to or further away from the second through hole 4212 within the second limiting channel 4221 under the influence of gravity. In other embodiments, the first sealing member 401 and the second sealing member 402 can be driven to move by a driver.

[0056] In some embodiments, the distance from the first limiting channel 4121 away from the first through hole 4112 to the end near the first through hole 4112, i.e., from the open end to the closed end of the first limiting channel 4121, increases. Similarly, the distance from the second limiting channel 4221 away from the second through hole 4212 to the end near the second through hole 4212, i.e., from the open end to the closed end of the second limiting channel 4221, increases. Taking the plane passing through the center line of the liquid storage cavity 150 as the reference plane 11, the reference plane 11 can be understood as the symmetrical plane of the liquid storage cavity 150. When the reference plane 11 cuts the first limiting channel 4121 and the second limiting channel 4221 at the same time, the end of the first limiting channel 4121 near the first through hole 4112 and the end of the second limiting channel 4221 away from the second through hole 4212 are located on the same side of the reference plane 11. That is, the blocked end of the first limiting channel 4121 and the open end of the second limiting channel 4221 are located on the same side of the reference plane 11.

[0057] In some embodiments, the extending directions of the first limiting channel 4121 and the second limiting channel 4221 are arranged at an angle, and the angle between the extending directions of the first limiting channel 4121 and the second limiting channel 4221 and the center line of the liquid storage cavity 150 is equal. For example, the angle between the extending directions of the first limiting channel 4121 and the second limiting channel 4221 and the center line of the liquid storage cavity 150 can be 45°. Of course, the extending directions of the first limiting channel 4121 and the second limiting channel 4221 and the center line of the liquid storage cavity 150 can also be arranged at an acute angle greater than or less than 45°. The plane containing the first limiting channel 4121 and the second limiting channel 4221 is arranged at an angle to the outer surface of the main unit used to cooperate with the spray device 10, and the outer surface extends along the axial direction of the liquid storage mechanism 100. In other embodiments, the angle between the extending directions of the first limiting channel 4121 and the second limiting channel 4221 and the center line of the liquid storage cavity 150 may not be equal. For example, the angle between the extension direction of the first limiting channel 4121 and the center line of the liquid storage cavity 150 is less than 45°, while the angle between the extension direction of the second limiting channel 4221 and the center line of the liquid storage cavity 150 is greater than 45°. When the spray device 10 is in operation, both the first channel 4031 and the second channel 4032 are located above the liquid storage cavity 150. At this time, due to the special structure of the first limiting channel 4121 and the second limiting channel 4221, the first sealing member 401 moves to the open end of the first limiting channel 4121 under its own gravity, thus opening the first channel 4031. Similarly, the second sealing member 402 moves to the open end of the second limiting channel 4221 under its own gravity, thus opening the second channel 4032. Therefore, the aerosol in the liquid storage cavity 150 can be discharged through the connecting hole 3151, the first channel 4031, the second channel 4032, and the spray hole 3221. When the spray device 10 is in a tilted state, there are two types of tilting states: horizontal tilting and inverted tilting. In the horizontal tilting state, the first channel 4031, the second channel 4032, and the liquid storage chamber 150 are approximately at the same height. In the inverted tilting state, the first channel 4031 and the second channel 4032 are located below the liquid storage chamber 150.

[0058] When the spray device 10 is in a horizontal tilted state, for example, when the blocking end of the first limiting channel 4121 is above the open end and the open end of the second limiting channel 4221 is above the blocking end, the first blocking member 401 will move to the open end of the first limiting channel 4121 under its own gravity to open the first channel 4031. However, the second blocking member 402 will move to the blocking end of the second limiting channel 4221 under its own gravity to close the second channel 4032. Therefore, the liquid in the liquid storage chamber 150 will not be able to enter the spray hole 3221 through the second channel 4032 to cause liquid leakage. For example, if the sealing end of the first limiting channel 4121 is located below the open end, and the open end of the second limiting channel 4221 is located below the sealing end, the first sealing member 401 will move to the sealing end of the first limiting channel 4121 under its own gravity to close the first channel 4031. However, the second sealing member 402 will move to the open end of the second limiting channel 4221 under its own gravity to open the second channel 4032. Therefore, the liquid in the liquid storage chamber 150 will not be able to enter the second channel 4032 through the first channel 4031, thereby preventing the liquid from flowing out of the spray hole 3221 and causing leakage. It can be understood that the outer side of the main unit matched with the spray device 10 extends along the axial direction of the liquid storage mechanism 100 and contacts the support when tilted. The support can be the ground or a table, etc. The plane where the first limiting channel 4121 and the second limiting channel 4221 are located extends along the axial direction of the liquid storage mechanism 100 and is set at an angle to the outer side. Therefore, regardless of the tilting state of the spray device 10, at least one of the first channel 4031 and the second channel 4032 is blocked, thus further improving the leak-proof effect.

[0059] When the spray device 10 is in an inverted and tilted state, the open end of the first limiting channel 4121 is above the blocking end, and the open end of the second limiting channel 4221 is above the blocking end. Therefore, the first blocking member 401 will move to the blocking end of the first limiting channel 4121 under its own gravity to close the first channel 4031, and the second blocking member 402 will move to the blocking end of the second limiting channel 4221 under its own gravity to close the second channel 4032. Thus, the first channel 4031 and the second channel 4032 are closed at the same time, which can also effectively prevent liquid from flowing out of the spray hole 3221 through the first channel 4031 and the second channel 4032 to constitute a leak.

[0060] It is understandable that when the spray device 10 is in the tilted state, since at least one of the first channel 4031 and the second channel 4032 is blocked, the high-pressure gas in the liquid storage chamber 150 cannot be discharged outside the spray device 10 through the first channel 4031 and the second channel 4032. Therefore, the high-pressure gas still enters the liquid storage chamber 150. Under the push of the gas pressure, the first sealing member 401 can seal the first through hole 4112 more tightly, and the second sealing member 402 can also seal the second through hole 4212 more tightly, thereby further improving the leak-proof effect of the spray device 10. It is also understandable that when the gas pressure in the liquid storage chamber 150 reaches a certain value, the air pump 20 that provides high-pressure gas will reach the stall pressure, thereby stopping the continued supply of gas and preventing the liquid storage mechanism 100 from being damaged due to excessive pressure in the liquid storage chamber 1501.

[0061] In some embodiments, the density of both the first sealing member 401 and the second sealing member 402 can be greater than the density of the liquid in the storage chamber 150. This effectively prevents the first sealing member 401 from stopping sealing the first through hole 4112 under the action of liquid buoyancy, and also effectively prevents the second sealing member 402 from stopping sealing the second through hole 4212 under the action of liquid buoyancy. This further improves the leak-proof effect of the spray device 10.

[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] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
