Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization equipment, and in particular to an oiler with a child lock and an electronic atomizer. Background Art

[0002] Electronic vaporizers are commonly used for medical nebulization therapy or as a cigarette replacement. A typical electronic vaporizer consists of an atomizer assembly and a power supply assembly. The atomizer assembly includes a reservoir, a core, and other components. The reservoir provides the core with the atomizer matrix (liquid) needed to generate aerosol. When powered on, the core heats the atomizer matrix to generate aerosol, and the power supply assembly provides the electrical energy required for heating the core. Some manufacturers pre-fill the reservoir with atomizer matrix when producing electronic vaporizers. However, this matrix is ​​prone to leaking and deteriorating during storage and transportation.

[0003] To solve the above problems, some manufacturers provide electronic atomizers with additional oil injectors, which are used by users to inject oil into the oil storage chamber when the user uses the device. This makes the operation more complicated for users. At the same time, since the oil injector cannot self-seal, it is not only prone to oil leakage during the oil injection process, but also when the oil injector is separated from the main body of the electronic atomizer, part of the atomized matrix is ​​also prone to leak out from the liquid outlet of the oil injector and the oil inlet of the atomizer. In addition, when minors who lack safety awareness touch the oil injector, they are likely to cause the atomized matrix in the oil injector that cannot self-seal to leak, thereby contaminating the atomizer and the environment. Utility Model Content

[0004] The main purpose of the utility model is to provide a lubricator and an electronic atomizer with a child lock, which can solve the problem in the prior art that the lubricator cannot be sealed after being separated from the main body of the electronic atomizer.

[0009] When the valve body moves to the end close to the liquid outlet, the valve body is away from the storage cavity, and the through hole is covered by the inner wall of the flow channel, so that the storage cavity is sealed.

[0010] The valve body in the oil injector can be kept at the end close to the liquid outlet under the assistance of the first external force or the self tension of the valve body, so that the oil reservoir is in a sealed state. When the valve body is moved to the end close to the liquid inlet under the pushing of the second external force, the through hole on the valve body is exposed to the storage cavity, and the atomized base in the storage cavity flows into the flow channel or the valve body through the through hole and is discharged from the liquid outlet. It is worth noting that the second external force is greater than the first external force or the self tension of the valve body, and the direction of action of the second external force is opposite to that of the first external force or the tension.

[0011] In some embodiments, a mounting cavity is defined on the oil reservoir and communicates with the flow channel, and a driving mechanism is arranged in the mounting cavity. One end of the driving mechanism is connected to the end of the valve body away from the storage cavity, and the other end of the driving mechanism is connected to the end of the mounting cavity close to the liquid inlet. The driving mechanism is used to provide a force away from the storage cavity for the valve body.

[0012] In some embodiments, the valve body comprises a first shell and a second shell. The first shell is fixed in the flow channel, and the second shell is movably arranged in the first shell. The second shell is hollow inside. An opening is arranged on the end of the second shell away from the storage cavity and communicates with the inside of the second shell. A through hole is arranged on the end of the second shell close to the storage cavity and communicates with the inside of the second shell. The outer wall of the second shell and the inner wall of the first shell define a mounting cavity. A driving mechanism is arranged in the mounting cavity. One end of the driving mechanism is connected to the second shell, and the other end of the driving mechanism is connected to the first shell. The driving mechanism is used to provide a force away from the liquid inlet for the valve body.

[0013] In some embodiments, the driving mechanism is an elastic member, which comprises a spring or a torsion spring, or an elastic arm made of rubber or silicone.

[0014] In some embodiments, the end of the second shell close to the storage cavity is at least partially exposed to the first shell or the storage cavity, and the radial dimension of the exposed part is greater than the inner diameter of the flow channel.

[0015] In some embodiments, a sealing gasket is arranged between the valve body and the oil reservoir.

[0016] In some embodiments, the opening and the through hole are filled with a porous oil guide medium in the valve body. Further, the porous oil guide medium is at least one of porous ceramic or cotton.

[0017] In some embodiments, the oil injector further includes a magnet, which is mounted on one end of the valve body close to the liquid outlet.

[0018] In some embodiments, the present application provides an electronic atomizer, comprising a housing and the aforementioned lubricator, wherein an oil storage cavity is provided in the housing, an installation space for accommodating the lubricator is provided on the housing, and the lubricator is removably installed in the installation space;

[0019] The oiler includes an oil tank, the oil tank defines a storage cavity for storing liquid, the oil tank is provided with a flow channel connecting the storage cavity with the outside, the flow channel has a liquid inlet connected to the storage cavity and a liquid outlet opposite to the liquid inlet;

[0020] a valve body, at least a portion of which is disposed within the flow channel and is movable between the liquid inlet and the liquid outlet, the valve body being hollow, and having an opening communicating with the interior of the valve body at one end of the valve body away from the storage chamber, and a through hole communicating with the interior of the valve body at one end of the valve body near the liquid inlet;

[0021] After the lubricator is installed in the installation space, the valve body moves to a position close to the liquid inlet under the action of an external force, and the valve body is at least partially located in the storage cavity, so that the through hole is exposed in the storage cavity and communicates with the storage cavity;

[0022] After the lubricator is removed from the installation space, the valve body moves to a position close to the liquid outlet under the action of external force, so that the through hole is covered by the inner wall of the flow channel and the storage cavity is sealed.

[0023] Compared with the prior art, the utility model has obvious advantages and beneficial effects. The valve body in the oiler can maintain the self-sealing state of the oil tank under the action of the spring. At the same time, the valve body can also open the oil tank under the action of external force, so that the atomized matrix in the oil tank can be output. For example, when the oiler is combined with the electronic atomizer, the valve body in the oiler can be opened by the electronic atomizer, so that the oil tank is connected with the oil storage chamber on the electronic atomizer; when the oiler is separated from the electronic atomizer, the valve body can be reset to the state of sealing the oil tank under the action of the spring, completing self-sealing.

[0035] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] In the description of this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise expressly limited. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0037] Electronic atomizers can be used in various fields, such as medical atomization, cosmetic atomization, and as alternative cigarettes. They primarily generate aerosols by heating an atomizing matrix, which can be a liquid matrix containing or not containing nicotine. Electronic atomizers generally include an atomizing assembly and a power supply assembly. The atomizing assembly includes an oil reservoir for storing the atomizing matrix and an atomizing core for heating and atomizing the atomizing matrix to generate an aerosol. The power supply assembly provides power to the atomizing core.

[0038] The oil reservoir of an electronic atomizer is relatively small and cannot sustain the long-term aerosol production. This requires the user to inject aerosolized matrix into the reservoir through an external container. Existing electronic atomizers include an oiler to provide additional aerosolized matrix to the oil reservoir. This oiler can be separated from the electronic atomizer, but when the oiler is separated from the electronic atomizer, some aerosolized matrix will leak out of the oiler's liquid outlet.

[0039] The present application provides an oiler with a child lock, which includes an oil tank 1 and a valve body 2 arranged on the oil tank 1, and the valve body 2 can move between a first position and a second position relative to the oil tank 1. The valve body 2 is hollow inside, and one end of the valve body 2 is provided with an opening 20 connected to the interior of the valve body 2, and the other end of the valve body 2 is provided with a through hole 21 connected to the interior of the valve body 2; wherein, when the valve body 2 moves to the first position, the through hole 21 is exposed in the oil tank 1 and connected to the oil tank 1; when the valve body 2 moves to the second position, the through hole 21 is hidden, and the oil tank 1 is sealed.

[0040] Specifically, the oil tank 1 defines a storage chamber 10 for storing liquid. The oil tank 1 is provided with a liquid inlet and a liquid outlet connected to the storage chamber 10. The liquid inlet is located at one end near the storage chamber 10, and the liquid outlet is located at one end near the exterior of the oil tank 1. The liquid inlet and the liquid outlet are connected to form a flow channel 11. It is understood that the length of the flow channel 11 can be the wall thickness of the oil tank 1. In some embodiments, the end near the liquid inlet is the first position, and the end near the liquid outlet is the second position.

[0041] The valve body 2 is installed on the oil tank 1. A through hole 21 is provided on the valve body 2 to form a flow channel 11 for the flow of the atomized matrix. The flow channel 11 can be switched between opening the oil tank 1 or sealing the oil tank 1 according to the relative state of the valve body 2 and the oil tank 1.

[0042] See also Figure 1 The valve body 2 is installed in the flow channel 11 connecting the oil tank 1 to the storage chamber 10. The interior of the valve body 2 is hollow. The end of the valve body 2 near the liquid outlet is provided with an opening 20, which is connected to the outside of the oil tank 1. The end of the valve body 2 near the storage chamber 10 is provided with a through hole 21 that is connected to the opening 20. When the valve body 2 moves to the second position near the liquid outlet, the end of the valve body 2 with the through hole 21 is hidden in the flow channel 11. The through hole 21 is covered by the inner wall of the flow channel 11 and cannot be connected to the storage chamber 10. At this time, the oil tank 1 is in a sealed state.

[0043] See also Figure 2 When the valve body 2 moves to the first position close to the liquid inlet, the through hole 21 of the valve body 2 is at least partially exposed to the storage chamber 10, so that the through hole 21 is connected to the storage chamber 10, and the atomized matrix in the storage chamber 10 enters the valve body 2 through the through hole 21 and is output from the opening 20 to the outside of the oil tank 1.

[0044] The lubricator includes a driving mechanism for driving the valve body 2 to move. The driving mechanism provides a force to keep the lubricator in a sealed state, thereby achieving self-sealing of the lubricator. The driving mechanism uses an elastic member, which includes a spring or a torsion spring, or an elastic arm made of rubber or silicone.

[0045] In some embodiments, the outer wall of the valve body 2 and the inner wall of the flow channel 11 define a mounting cavity 29. The mounting cavity 29 has a first sidewall and a second sidewall that are relatively movable. The first sidewall is provided by the valve body 2, and the second sidewall is provided by the oil tank 1. A spring 22 is disposed within the mounting cavity 29. One end of the spring 22 is connected to the first sidewall, and the other end of the spring 22 is connected to the second sidewall. The support of the spring 22 maintains the valve body 2 in the second position away from the storage chamber 10, so that the through hole 21 is hidden in the flow channel 11. It should be noted that a torsion spring or an elastic arm can directly replace the spring 22.

[0046] See also Figure 3The valve body 2 includes a first housing 27 and a second housing 28. The first housing 27 defines a receiving chamber and is fixed within the flow channel 11. The second housing 28 is movably disposed within the receiving chamber of the first housing 27. The second housing 28 is hollow. An opening 20 communicating with the interior of the second housing 28 is provided at the end of the second housing 28 away from the storage chamber 10. A through hole 21 communicating with the interior of the second housing 28 is provided at the end of the second housing 28 near the storage chamber 10. The outer wall of the second housing 28 and the inner wall of the first housing 27 define a mounting chamber 29. A spring 22 is disposed within the mounting chamber 29. One end of the spring 22 is connected to the end of the valve body 2 away from the storage chamber 10, and the other end of the spring 22 is connected to the side of the flow channel 11 near the storage chamber 10. The spring 22 provides a force to move the valve body 2 away from the storage chamber 10. It should be noted that in some embodiments, the first housing 27 may be an oil tank 1.

[0047] One end of the second shell 28 close to the storage chamber 10 is at least partially exposed in the first shell 27 or the storage chamber 10, and the radial dimension of the exposed portion is larger than the inner diameter of the flow channel 11. Figure 3 As shown, the second housing 28 has a longitudinal portion extending toward the liquid outlet and a transverse portion connected to the longitudinal portion. An opening 20 is provided on the side of the longitudinal portion near the liquid outlet, communicating with the exterior of the oil tank 1. A through-hole 21 is provided on the side of the longitudinal portion near the storage chamber 10, communicating with the opening 20. The transverse portion is disposed within the storage chamber 10 and abuts against the inner wall of the storage chamber 10. In some embodiments, the second housing 28 is supported by a spring 22, causing the transverse portion to abut against the inner wall of the storage chamber 10, thereby concealing the through-hole 21 within the first housing 27. When the second housing 28 is pushed toward the storage chamber 10 by an external force, the spring 22 is compressed, and the longitudinal portion is gradually exposed within the storage chamber 10 until the through-hole 21 is exposed within the storage chamber 10.

[0048] In some embodiments, a sealing gasket is provided between the valve body 2 and the oil tank 1. Figure 3 As shown, the sealing gasket surrounds the valve body 2. Furthermore, a first sealing gasket 23 and a second sealing gasket 24 are provided between the valve body 2 and the oil tank 1. The first sealing gasket 23 is provided on a side close to the storage chamber 10, and the second sealing gasket 24 is provided on a side close to the liquid outlet. When the valve body 2 moves between the first position and the second position, at least one sealing gasket is filled between the valve body 2 and the oil tank 1.

[0049] In some embodiments, as Figure 4 As shown, a porous oil-conducting medium 25 is filled in the valve body 2 between the opening 20 and the through hole 21. The atomized matrix can be distributed into a number of fine fluids by the porous oil-conducting medium 25 and output from the oil tank 1 by the porous oil-conducting medium 25 through capillary action. Figure 5As shown, when the valve body 2 is in the first position, the through hole 21 is connected to the storage chamber 10, and the atomized matrix enters the porous oil-conducting medium 25 and is discharged along the liquid outlet. Furthermore, the porous oil-conducting medium 25 can be a porous ceramic material or cotton.

[0050] In some embodiments, as Figure 6 As shown, the oiler further includes a magnet 26, which is mounted on the valve body 2 at one end near the first position. The magnet 26 pushes the valve body 2 from the first position to the second position under the action of magnetic repulsion. After the magnetic repulsion disappears, the tension of the spring 22 forces the valve body 2 to move from the second position to the first position. Figure 7 As shown, a magnet 3 with the same polarity as the magnet 26 is placed on the outer wall of the oil tank 1 close to the magnet 26. The magnet 26 pushes the valve body 2 from the first position to the second position under the action of the magnetic repulsive force.

[0051] Based on the above-mentioned oiler, the present application provides an electronic atomizer, which includes a shell and the oiler in the aforementioned embodiment, wherein an oil storage chamber is provided in the shell, and an installation space for accommodating the oiler is provided on the shell, and the oiler is removably installed in the installation space; after the oiler is installed in the installation space, the valve body 2 is close to the first position under the action of external force, and the valve body 2 is at least partially located in the storage chamber 10, so that the through hole 21 is exposed in the storage chamber 10 and connected to the storage chamber 10; after the oiler is removed from the installation space, the valve body 2 is close to the second position under the action of external force, and the through hole 21 is covered by the inner wall of the flow channel 11, and the storage chamber is sealed.

[0052] Specifically, in some embodiments, when the oiler is not combined with the electronic atomizer, the valve body in the oiler can be maintained at one end close to the liquid outlet with the help of a first external force or its own tension, so that the oil tank is in a sealed state; after the oiler is connected to the shell assembly of the electronic atomizer, the valve body is pushed by a second external force to move to one end close to the liquid inlet, so that the through hole on the valve body is exposed to the storage cavity, and the atomized matrix in the storage cavity flows into the flow channel or the valve body through the through hole and is discharged from the liquid outlet. It is worth noting that the extrusion force generated by the connection between the oiler and the shell when the two are combined is the second external force, the second external force is greater than the first external force or the self-tension of the valve body, and the direction of action of the second external force is opposite to the direction of action of the first external force or tension.

[0053] The above description is only part or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
