[0035] The invention provides an atomizer.

[0036] Please refer to Figures 1 to 5 In an embodiment of the present invention, the atomizer comprises:

[0037] A housing 10, wherein a main oil tank 11, an auxiliary oil tank 12 and an atomizing tank 13 are arranged in the housing 10, wherein the atomizing tank 13 is connected to the auxiliary oil tank 12, an oil guide channel 16 is arranged between the main oil tank 11 and the auxiliary oil tank 12, and the housing 10 is further provided with an air outlet 15 connected to the atomizing tank 13;

[0038] An atomizer core assembly 20, wherein the atomizer core assembly 20 is disposed in the atomizer bin 13;

[0039] The solenoid valve switch 30 is disposed in the main oil tank 11 and can block or open the oil guide channel 16 to control the oil in the main oil tank 11 to enter the atomization tank 13 via the auxiliary oil tank 12 .

[0040] In this embodiment, the shell 10 can be made of a plastic material with good heat insulation performance, so that the user will not be burned by the high temperature inside during the smoking process. The shell 10 can be designed in a variety of shapes, for example, the cross-sectional profile of the shell 10 can be an ellipse or a shuttle shape, etc. Such shapes conform to ergonomic design and are easy for users to hold.

[0041] It can be understood that the number of auxiliary oil tanks 12 in the present application can be set to multiple, such as two, three, or more, and the multiple auxiliary oil tanks 12 are connected in series and conductive. In this way, when the oil in the main oil tank 11 passes through multiple auxiliary oil tanks 12 in turn and then enters the atomization tank 13, the risk of oil leakage is further reduced by flowing through layer by layer.

[0042] Therefore, when the atomizer of the technical solution of the present invention needs to atomize the atomizer core assembly 20 in the atomizer bin 13, the oil guide channel 16 can be connected by controlling the solenoid valve switch 30, so that part of the oil in the main oil bin 11 enters the auxiliary oil bin 12, and then enters the atomizer bin 13 from the auxiliary oil bin 12 for atomization. Since the oil bin is divided into two, the amount of oil in the auxiliary oil bin 12 is relatively small, so that the pressure of the oil in the auxiliary oil bin 12 is also small, and the oil is not easy to cross and flow, so that when the oil enters the atomizer bin 13, it is not easy to penetrate or leak from the auxiliary oil bin 12 and the atomizer bin 13, and the solenoid valve switch 30 maintains the closed environment in the oil bin, so that the oil bin is less affected by the external air pressure and temperature changes, which greatly reduces the possibility of oil leakage. At the same time, the solenoid valve switch 30 is set in the main oil bin 11, so that the solenoid valve switch 30 and the main oil bin 11 are integrated into one, without occupying other additional space, making the inside of the atomizer more compact and the whole more compact to meet user needs.

[0043] Reference Figure 3 In one embodiment of the present application, the solenoid valve switch 30 includes an electromagnetic core 31 and a coil 32. The electromagnetic core 31 is contained in the main oil tank 11, and the coil 32 is sleeved outside the main oil tank 11. The coil 32 is energized to drive the electromagnetic core 31 to move and block or open the oil guide channel 16. The coil 32 is energized to form an energized solenoid, and a magnetic force is generated inside the coil 32 to repel or attract the electromagnetic core 31, so that the electromagnetic core 31 moves to open or block the oil guide channel 16. In this embodiment, the electromagnetic core 31 and the coil 32 are respectively arranged inside and outside the main oil tank 11, so that the electromagnetic valve switch 30 and the main oil tank 11 are formed as one body, so that the internal space of the atomizer is more compact, the space volume is reduced, and the overall size is more compact to meet user needs.

[0044] Reference Figure 4 and Figure 5, further, in one embodiment of the present application, the solenoid valve switch 30 also includes an elastic member 33 disposed in the main oil tank 11, one end of the elastic member 33 is connected to the inner wall of the main oil tank 11, and the other end is in contact with the electromagnet core 31, so as to drive the electromagnet core 31 to move and block the oil guide channel 16. In this embodiment, the solenoid valve switch 30 is a normally closed switch. In actual situations, when the coil 32 is energized, the electromagnetic core 31 is driven by magnetic force to move and separate from the oil guide channel 16, so that the oil guide channel 16 is turned on, and at the same time, the action of the electromagnetic core 31 also causes the elastic member 33 to deform and store elastic potential energy; when the coil 32 is de-energized, the coil 32 no longer generates magnetic force to act on the electromagnetic core 31, and at this time, the elastic member 33 releases the stored elastic potential energy and pushes the electromagnetic core 31 to re-block the oil guide channel 16, completing the switching process. Specifically, the elastic member 33 can be a spring, or an elastic body that can restore deformation, such as a spring. By setting the elastic member 33, it is not necessary to swap the positive and negative electrodes during the process of controlling the solenoid valve switch 30. After power is cut off, the oil guide channel 16 can be automatically blocked by relying on the elastic potential energy, making the switch operation process simpler and more reliable.

[0045] Reference Figure 4 In the embodiment of the present application, the main oil tank 11 has a first accommodating portion 113 and a second accommodating portion 115 that are interconnected, the oil guide channel 16 is connected to the first accommodating portion 113, the coil 32 is sleeved on the outside of the second accommodating portion 115, and the electromagnetic core 31 is partially located in the second accommodating portion 115, and the other part is located in the first accommodating portion 113 to block or conduct the oil guide channel 16. It can be understood that both the first accommodating portion 113 and the second accommodating portion 115 can be used to store oil, so that more oil can be stored in the main oil tank 11, and the coil 32 is sleeved on the outside of the second accommodating portion 115 to form an integral body, which, on the one hand, makes the installation structure of the electromagnetic valve switch 30 relatively simple, so that the coil 32 can be relatively stable and reliable with the main oil tank 11, and on the other hand, it can also effectively control the electromagnetic core 31 to conduct the oil guide channel 16 through the magnetic force generated by the coil 32 after it is energized, and has high reliability.

[0046] Furthermore, in the present application, the central axis of the second accommodating portion 115 coincides with the central axis of the first accommodating portion 113, that is, the distances between the two sides of the second accommodating portion 115 and the two sides of the first accommodating portion 113 are respectively equivalent, so that the second accommodating portion 115 is located at the center of the first accommodating portion 113, so that the internal electromagnet core 31 is also located at the center, and the electromagnet core 31 will not be disturbed by the inner wall of the main oil tank 11 during operation, and in the process of oil guiding, the oil flow in all directions in the main oil tank 11 is uniform, and the efficiency of oil circulation is high.

[0047] In order to ensure that the electromagnetic core 31 maintains normal operation in the main oil tank 11 and reduce the volume of the main oil tank 11, in one embodiment of the present application, the cross-sectional shape and size of the second accommodating portion 115 are adapted to the cross-sectional shape and size of the electromagnetic core 31. In this embodiment, the cross-sectional area of ​​the second accommodating portion 115 is smaller than the cross-sectional area of ​​the first accommodating portion 113. For example, when the shape of the electromagnetic core 31 is designed to be cylindrical, the shape of the second accommodating portion 115 is also designed to be a cylindrical shape of comparable size, so that the electromagnetic core 31 can extend into the second accommodating portion 115, and also has a movable gap, thereby further reducing the overall volume of the main oil tank 11.

[0048] Combined with reference Figure 2 In one embodiment of the present application, the main oil tank 11 includes a first oil tank shell 111, and the auxiliary oil tank 12 includes a second oil tank shell 121. The first oil tank shell 111 and the second oil tank shell 121 are interconnected and detachably disposed in the outer shell 10.

[0049] Specifically, in the present embodiment, the first oil tank shell 111 and the second oil tank shell 121 can be an integral structure. By detachably arranging the first oil tank shell 111 and the second oil tank shell 121 in the outer shell 10, the shell of the atomizer oil tank and the outer shell 10 are designed as a split type, which is convenient for disassembly of the oil tank shell for maintenance and care. At the same time, it is also convenient to take out the first oil tank shell 111 and the second oil tank shell 121 for refueling and other operations, thereby improving the convenience of users in daily use.

[0050] Furthermore, since the coil will generate high temperature after being energized, the first oil tank shell 111 and the second oil tank shell 121 of the present application can both be made of high temperature resistant plastic material to provide heat insulation and protect the oil tank. At the same time, since the coil 32 is sleeved on the outside of the first oil tank shell 111, and the first oil tank shell 111 is made of plastic material and is not conductive, the coil 32 will not be affected by the first oil tank shell 111 after being energized, ensuring the normal operation of the solenoid valve switch 30.

[0051] Furthermore, the cross-sectional profile of the first oil tank shell 111 of the present application is an ellipse; and / or, the cross-sectional profile of the second oil tank shell 121 is an ellipse. It can be understood that, with such a configuration, on the one hand, the ellipse design conforms to the ergonomic design, and is convenient for people to hold for refueling, maintenance and other operations; on the other hand, the cross-sectional profile of the first oil tank shell 111 and / or the second oil tank shell 121 is designed to be an ellipse, so that the shell wall of the first oil tank shell 111 and / or the second oil tank shell 121 will not form corners, but is relatively smooth, so when the oil flows on the inner wall surface, the time it stays on the inner wall surface is also short, thereby greatly improving the oil flow efficiency and oil utilization.

[0052] Of course, in other embodiments, the cross-sectional profiles of the first oil bin shell 111 and the second oil bin shell 121 may also be other shapes, including but not limited to circular, square, etc.

[0053] Combined with reference Figure 2 , Figure 3 In one embodiment of the atomizer of the present application, the atomizer core assembly 20 includes an atomizer core body 21 and an electric heating wire wound around the outside of the atomizer core body 21, and the atomizer includes a power module 40, the power module 40 is electrically connected to the electric heating wire, and the oil in the atomizer bin 13 is adsorbed in the atomizer core body 21. Among them, the atomizer core body 21 can be a cotton core, which has a better taste, a higher degree of reduction of the oil, and a denser amount of smoke. Of course, the atomizer core body 21 can also be a ceramic core, which is stable and durable, easy to clean, and not prone to the phenomenon of sticking the core; and the electric heating wire can be a stainless steel wire, a nickel wire, or a nickel-chromium alloy wire with good heat transfer performance and low cost. In actual application, when the electric heating wire is connected to the power module 40, the electric heating wire heats up and atomizes the oil adsorbed in the atomizer core body 21. After the oil is heated, smoke is generated and flows out through the air outlet 15 for the smoker to inhale.

[0054] Furthermore, the atomizer core assembly 20 of the present application further includes a sealing sleeve 22, which is sleeved on the outer side of the atomizer core body 21. The sealing sleeve 22 may be a silicone sleeve. It can be understood that by providing the sealing sleeve 22, the oil adsorbed in the atomizer core body 21 is not easy to drip, and the oil is atomized by the heating wire after heating, thereby improving the utilization rate of the oil in the atomizer core body 21.

[0055] The present invention further provides an electronic cigarette, which includes an atomizer and an electronic cigarette body connected to the atomizer. The specific structure of the atomizer refers to the above embodiment. Since the electronic cigarette adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0056] In one embodiment, the atomizer is plugged into the electronic cigarette body, and the power module 40 is arranged in the electronic cigarette body. When the atomizer is plugged into the electronic cigarette body, it is connected to the power module 40 through the electrode, so that the atomization process of the atomizer and the on and off process of the solenoid valve switch 30 can be controlled by pressing a button on the electronic cigarette body.

[0057] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
