Abstract
Description
Technical Field
[0001] The present application relates to the field of electronic cigarettes, and in particular to a quantitative oil spraying electronic cigarette. Background Art
[0002] Traditional e-cigarettes mainly achieve atomization of e-liquid by heating and atomization to produce an inhalation experience similar to traditional smoke. Such products usually use a heating net to wrap multiple layers of cotton (usually 5 to 6 layers), and wrap the oil storage cotton on the outside, and the oil penetrates through small holes. However, this design has significant shortcomings.
[0003] First, since the oil penetrates into the atomizer core through small holes, it is difficult to control the amount of oil, which can easily lead to unstable taste. During use, users often encounter situations where the taste is sometimes good and sometimes bad. This inconsistency greatly reduces the user experience. In addition, the atmospheric pressure and temperature in different regions will also affect the penetration of the oil, further exacerbating the instability of the taste. For example, in high altitude areas or cold climates, the fluidity of the oil may be reduced, resulting in poor atomization effect.
[0004] Secondly, traditional designs rely on multiple layers of cotton to store and conduct oil, and the thickness and quality of the cotton layer have a direct impact on the oil conduction effect. In addition, due to the limited oil absorption capacity of the cotton layer, oil leakage or dry burning is prone to occur, affecting user safety and product life. Utility Model Content
[0005] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a quantitative oil-spraying electronic cigarette, which uses an oil pump to accurately control the amount of oil sprayed, and can spray oil to a cotton-free atomization core, an atomization core with less cotton, or a traditional atomization core, thereby achieving a more stable taste.
[0006] To achieve the above-mentioned purpose, the present application discloses a quantitative oil-spraying electronic cigarette, comprising an electronic cigarette body, an oil-spraying assembly, and an atomizing core, wherein the electronic cigarette body has an oil tank, a working channel, a battery, and a control board connected to the battery; the atomizing core is installed in the working channel and connected to the control board, and is powered and controlled by the control board; the oil-spraying assembly is divided into an oil pump and a driving part for driving the oil pump to work, wherein the oil pump is located in the oil tank, the driving part is located outside the oil tank, and at least the driving rod of the driving part extends into the oil tank to drive the oil pump to work; the oil pump has an oil inlet close to the bottom of the oil tank and a nozzle extending into the working channel and opposite to the atomizing core.
[0007] In some embodiments, the mist is a cotton-free heating net;
[0008] In other embodiments, the atomizer core includes a heating net and 1 or 2 oil storage layers wrapped around the heating net.
[0009] In some embodiments, the driving unit is a motor.
[0010] In some embodiments, the upper end of the working channel is connected to the mouthpiece, and the lower end is connected to the outside.
[0011] In some embodiments, the oil tank has an openable oil filling hole.
[0012] In some embodiments, an inhalation sensor for sensing the negative pressure value of the working channel is disposed in the electronic cigarette body, and the inhalation sensor is connected to the control board.
[0013] In some embodiments, the oil tank is a flexible structure that dynamically compensates for internal pressure changes during liquid output through deformation, thereby ensuring a stable liquid supply.
[0014] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0024] Figure 1 An exemplary structure for achieving the technical purpose of the present application is shown, and specifically discloses a quantitative oil-spraying electronic cigarette, including an electronic cigarette body 1, an oil-spraying assembly 2 and an atomizing core 3.
[0025] The electronic cigarette body 1 is designed as a handheld device as a whole, and has a shell 101. The shell 101 is made of high temperature resistant and corrosion resistant materials to ensure its safety and durability during use. The electronic cigarette body 1 forms an oil tank 102 in the shell 101, and a working channel 103 runs through the oil tank 102. A battery (not shown in the figure) and a control board (not shown in the figure) connected to the battery are also arranged in the shell 101.
[0026] The battery in the electronic cigarette body 1 provides power for the entire device, and the battery is a rechargeable lithium battery. The battery supplies power to the control board, which controls the working state of the oil injection assembly 2 and the atomization core 3 through the control board, thereby realizing the normal operation of the electronic cigarette.
[0027] As a further description of this embodiment, the oil tank 102 is used to store the electronic cigarette oil, and is usually made of transparent or translucent material to facilitate the user to observe the remaining amount of the electronic cigarette oil at any time.
[0028] In some embodiments, an openable oil filling hole (not shown in the figure) is provided on the oil tank 102 , and the user only needs to open the oil filling hole cover to conveniently fill the oil into the oil tank, thereby avoiding frequent disassembly of the electronic cigarette body 1 .
[0029] In some embodiments, the oil tank 102 is designed to be a fully sealed structure. To meet the needs of its normal operation, the oil tank 102 is a flexible structure that dynamically compensates for internal pressure changes during liquid output through deformation, thereby ensuring a stable liquid supply.
[0030] Specifically, as a structural requirement for realizing a non-fully sealed structure, an air inlet hole (not shown in the figure) for compensating air pressure is provided on the oil tank 102 at a position away from the liquid surface.
[0031] It is understandable that in order to prevent oil from overflowing, the air inlet is designed as a one-way air inlet, and a one-way valve-like structure is made of silicone material. This one-way valve can allow air to enter the oil tank when needed, but prevent oil from overflowing from the air inlet.
[0032] The working channel 103 is used to accommodate the atomizer core 3 and output the atomized smoke. Structurally, the upper end of the working channel 103 is connected to the mouthpiece 104 to transfer the atomized smoke to the user, and the lower end is connected to the outside.
[0033] In this embodiment, the oil injection assembly 2 is composed of an oil pump 201 and a driving unit 202. The oil pump 201 is located in the oil tank 102. As a better choice, the oil pump 201 is a gear pump, and the driving unit 202 is a motor, whose oil inlet is located at the tail end, close to the bottom of the oil tank 102, so as to make full use of the electronic cigarette oil in the oil tank 102. The gear pump sprays the electronic cigarette oil onto the atomizing core 3 in a quantitative manner through a nozzle 203 directly facing the atomizing core 3 in the working channel. The driving unit 202 is located outside the oil tank 102 and cooperates with the oil pump 201 to drive the gear pump to work.
[0034] It is understandable that the oil inlet of the oil pump 201 is close to the bottom of the oil tank 102 , so that the electronic cigarette oil in the oil tank 102 can be fully utilized.
[0035] As the working core of the electronic cigarette, the atomizer core 3 is powered by the control board and its operation is controlled.
[0036] Based on the design of the oil spray assembly 2, the atomizer core 3 can adopt a cotton-free heating net design, or can include a heating net and 1 or 2 layers of oil storage cotton wrapped outside the heating net.
[0037] The function of the atomizer core 3 is to quickly heat the oil sprayed thereon and atomize it into smoke for the user to inhale.
[0038] The heating net in the atomizer core 3 is usually made of a material with high thermal conductivity, such as nickel-chromium alloy, to achieve rapid heating and uniform atomization.
[0039] In some more preferred solutions, an inhalation sensor connected to the control board is also provided in the electronic cigarette body 1 .
[0040] The working principle and action of this embodiment are as follows: when the inhalation sensor senses the negative pressure change in the working channel 103, the control board starts the driving unit 202, and the driving unit 202 drives the oil pump 201 to work. The oil pump 201 draws electronic cigarette oil from the bottom of the oil tank and sprays the oil quantitatively onto the atomizer core 3 in the working channel 103 through the nozzle 203. The atomizer core 3 quickly heats and atomizes the oil, and the user inhales the atomized smoke.
[0041] This embodiment achieves the effects of quantitative oil injection and uniform atomization, and has the advantages of being stable, reliable, and easy to use.
[0042] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
