Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a spliced ​​electronic cigarette cartridge and an electronic cigarette with adjustable flavor. Background Art

[0002] Electronic cigarettes, also known as e-cigarettes, are products that replace traditional cigarettes, mainly used to quit smoking and replace cigarettes. They have the same appearance and taste as cigarettes, and even have many more flavors than ordinary cigarettes. They can also inhale smoke, taste and feel like cigarettes. Electronic cigarettes do not have other harmful ingredients such as tar and suspended particles in cigarettes, nor do they have diffuse or lingering secondhand smoke. Compared with traditional cigarettes, electronic cigarettes are less harmful to the human body and the environment.

[0003] Electronic cigarettes usually include a liquid storage cup, an atomizer component, and a power supply component. During use, the atomizer component generates heat to atomize the liquid, which is then inhaled into the user's mouth along with air. Traditional electronic cigarettes only meet the user's physiological needs to relieve their addiction to smoking, and cannot allow users to experience more fun. The common electronic cigarettes on the market currently have a single flavor, and generally can only carry one cartridge. It is not possible to smoke two flavors at the same time, and it is difficult to stimulate user creativity.

[0004] Based on the above problems, existing electronic cigarette products or related patents have also developed or disclosed various electronic cigarettes with two or more cartridges that can satisfy users' different tastes. However, such existing electronic cigarettes still have the following problems:

[0005] 1) Using multiple cartridges has a complex structure and is usually difficult to replace. The flavors are limited and it is often difficult to switch or mix flavors. At the same time, there is a problem of cross-flavor leakage between multiple cartridges.

[0006] 2) Use relatively independent circuits to power each cartridge separately, and select the target cartridge by controlling the on and off of each cartridge power supply circuit to meet different taste requirements. However, this mode has a relatively complex circuit design, high manufacturing cost, requires certain operations when using, and has a shorter service life than traditional electronic cigarettes.

[0007] In addition, the above-mentioned various types of multi-flavor electronic cigarettes cannot achieve multiple flavors by simply modifying the cigarette cartridges based on the existing electronic cigarette host. For users who have already purchased the host, they need to purchase the host and the matching electronic cigarette cartridges separately, which has a high consumption cost. Summary of the invention

[0008] The purpose of the present invention is to provide an electronic cigarette with a simple structure, convenient use and low cost to achieve adjustable flavor, so as to solve at least one of the above problems. The following technical solutions are specifically adopted:

[0009] The first aspect of the present invention discloses a spliced ​​electronic cigarette cartridge, comprising a first cartridge and a second cartridge that can be spliced ​​into one, wherein the first cartridge and the second cartridge are respectively provided with an atomization assembly and a liquid storage chamber, and are respectively provided with an air outlet on the top, an air inlet and a single electrical connection part on the bottom, and are respectively provided with a mutually matching snap-in structure and a pair of electrical connection structures on the splicing surface; when the first cartridge and the second cartridge are spliced ​​into one, the top is spliced ​​into a suction nozzle, and the single electrical connection part at the bottom is used to couple the positive and negative output electrode contacts of the electronic cigarette host to obtain electricity, and at the same time, the electrical connection structures between the first cartridge and the second cartridge are connected to each other, forming two parallel circuit branches with the internal circuit, and the heating elements in the atomization assemblies of the first cartridge and the second cartridge are respectively coupled to one of the branches.

[0010] Furthermore, the clamping structure on the joint surface of the first cigarette cartridge and the second cigarette cartridge includes:

[0011] At least one group of protrusions and / or grooves are arranged on the first cigarette cartridge joint surface, and grooves and / or protrusions are arranged on the second cigarette cartridge joint surface and match the protrusions / grooves on the first cigarette cartridge joint surface.

[0012] Furthermore, the electrical connection structure on the joint surface of the first cigarette cartridge and the second cigarette cartridge includes a group of mutually matching conductive contacts / conductive slots respectively arranged on the joint surface of the first cigarette cartridge and the joint surface of the second cigarette cartridge.

[0013] The second aspect of the present invention discloses an electronic cigarette with adjustable flavor, comprising:

[0014] A host, comprising a housing and a power module and an electronic control module disposed in the housing, wherein the opening end of the housing forms a plug-in cavity, and a pair of positive and negative output electrode contacts of the electronic control module are located at the bottom of the plug-in cavity;

[0015] And a first type of electronic cigarette cartridge adapted to the host, the first type of electronic cigarette cartridge is a spliced ​​electronic cigarette cartridge as described in the first aspect above, when the spliced ​​electronic cigarette cartridge is spliced ​​into one piece, the bottom matches the plug-in cavity, and when the bottom of the spliced ​​body is inserted into the plug-in cavity, the single-connection electrical parts of the first cartridge and the second cartridge respectively abut the positive and negative output electrode contacts of the electronic cigarette host.

[0016] Furthermore, one of the liquid storage chambers of the first cigarette cartridge and the second cigarette cartridge is used to be filled with nicotine-containing e-liquid, and the other liquid storage chamber is used to be filled with a flavoring liquid that does not contain nicotine.

[0017] Furthermore, the bottoms of the first and second cigarette cartridges are respectively provided with a first magnetic unit, and the bottom of the plug-in cavity is also provided with a second magnetic unit corresponding to the first magnetic unit and having a different polarity, and the two attract each other when they are close to each other.

[0018] Furthermore, the power module and the electronic control module are integrated into a core body and installed in the shell, and an air flow channel connected to the plug-in cavity is provided inside, and the air outlet of the air flow channel is located at the bottom of the plug-in cavity; at least one air inlet connected to the air flow channel is provided on the shell.

[0019] Furthermore, an airflow sensing unit coupled to the electronic control module is provided in the air intake passage, and the electronic control module is used to connect the power supply circuit based on the airflow signal detected by the airflow sensing unit to output the working current through the output electrode contact.

[0020] Furthermore, the power module includes a battery and a power management circuit, and the other end of the shell is provided with a charging interface coupled to the power module.

[0021] Furthermore, the electronic control module is also configured with an information prompting unit, which includes an LED light and / or a vibrator for indicating a working status or issuing a vibration prompt.

[0022] Furthermore, the flavor-adjustable electronic cigarette of the present invention also includes a second type of electronic cigarette cartridge adapted to the host, the second type of electronic cigarette cartridge includes an atomization component and a liquid storage chamber, and is respectively provided with an air outlet and an air inlet at the top and the bottom; the appearance of the second type of electronic cigarette cartridge is consistent with the appearance of the spliced ​​body formed after splicing the spliced ​​electronic cigarette cartridges.

[0023] The beneficial technical effects of the present invention are as follows:

[0024] 1) The dual-cartridge design allows two cartridges to be configured with different flavors of e-liquid according to demand, which can meet the different taste requirements of users.

[0025] 2) The structural design of two cigarette cartridges connected to the main unit after splicing makes it easy to replace cigarette cartridges with different flavors and is easy to install and use. At the same time, the shape of the spliced ​​cigarette cartridge is the same as the structure of the original single cigarette cartridge, so that multiple flavors can be switched without changing the main unit, only the cigarette cartridge, which greatly reduces the user's consumption cost.

[0026] 3) After being spliced, the two cartridges are connected to each other through an electrical connection portion, and together with the output circuit of the electronic control module, they form two parallel branches in the same circuit loop. With this design, the electronic control module does not need to independently design multiple power supply circuits, which greatly saves design and manufacturing costs. At the same time, it also reduces the complexity of the host design and helps to increase the service life of the host. Similarly, for consumers who have already purchased a single-cartridge host, they can adjust a variety of flavors by replacing the spliced ​​cartridges of the present invention without having to repurchase a host.

[0027] 4) It adopts an intelligent control method that combines an airflow sensor with an electronic control module. When in use, you can directly suck the nozzle to start the host to generate smoke, without the need for additional switches and selection operations, providing a good user experience.

[0040] In order to further understand the present invention, preferred embodiments of the present invention are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0041] Example 1

[0042] Reference Figure 1-4 The first illustrative embodiment of the present invention discloses a spliced ​​electronic cigarette cartridge, which includes a first cartridge 1 and a second cartridge 2 that can be spliced ​​into one. The tops of the first cartridge 1 and the second cartridge 2 are respectively provided with air outlets 11 and 21, and the bottoms are provided with air inlets 17 and 27. After splicing, the upper ends of the first cartridge 1 and the second cartridge 2 together form a mouthpiece 100.

[0043] refer to Figure 4 The first cigarette cartridge 1 and the second cigarette cartridge 2 each include an atomizer assembly 28 and a shell mounted on the atomizer assembly 28, and the space inside the shell is used as a liquid storage chamber. A pipe 29 connecting the atomizer assembly and the air outlet is also provided in the shell to guide the smoke to the mouthpiece 100.

[0044] Reference Figure 2 and 3 In this exemplary embodiment, the bottom of the first cigarette cartridge 1 and the second cigarette cartridge 2 are respectively provided with single electrical connection parts 15 and 25, which are metal contacts, coupled to the internal circuit of the atomization component, and used to connect to the output electrode contacts of the electronic cigarette host to obtain electricity. At the same time, the joint surfaces of the first cigarette cartridge 1 and the second cigarette cartridge 2 are respectively provided with mutually matching clamping structures and a pair of electrical connection structures. Figure 3 The snap-on structure on the joint surface of the second cartridge 2 includes bosses 221, 241 and grooves 222, 242 respectively arranged on the upper and lower parts of the joint surface, and the corresponding joint surface of the first cartridge 1 is provided with grooves and bosses matching the bosses 221, 241 and grooves 222, 242, so that when the first cartridge 1 and the second cartridge 2 are joined, the positioning and snap-on are achieved through the matching set of the bosses and grooves, making the joint more convenient and reliable. At the same time, a group of electrical connection components are also provided on the joint surface of the second cartridge 2, including a conductive contact 231 and a conductive slot 232 coupled to the internal circuit of the atomizer assembly; correspondingly, the joint surface of the first cartridge 1 is provided with a conductive slot and a conductive contact corresponding thereto. Thus, when the first cigarette cartridge 1 and the second cigarette cartridge 2 are spliced ​​together, the above-mentioned conductive contacts and conductive slots are plugged together to form two conductive paths, thereby forming two parallel branches in the same circuit loop between the two single electrical connections 15 and 25, and the atomization components of the first cigarette cartridge and the second cigarette cartridge are respectively coupled to one of the branches.

[0045] With the above design, the two cartridges can store different flavors or types of e-liquids to meet the needs of multiple flavors. At the same time, after splicing, the electrical connection structure between the two cartridges forms a parallel circuit connection relationship, so that the spliced ​​cartridge only needs a pair of positive and negative output electrode contacts of the host to be powered, which simplifies the design and manufacturing cost of the host and makes it applicable to the original host with a single cartridge, reducing the consumption cost of users.

[0046] As a further preferred example, see the attached Figure 2 The bottom of the first cigarette cartridge 1 and the bottom of the second cigarette cartridge 2 are also respectively provided with magnetic adsorption units 16 and 26, which can match the magnetic adsorption units on the host to adsorb the assembled cigarette cartridges on the host.

[0047] Example 2

[0048] The second illustrative embodiment of the present invention discloses an electronic cigarette with adjustable flavor, which includes a host and a first type of electronic cigarette cartridge adapted therewith, wherein the first type of electronic cigarette cartridge is the spliced ​​electronic cigarette cartridge in the above-mentioned embodiment 1.

[0049] See attached Figure 5-7 The host comprises a shell 31 and an integrated core 4 installed in the shell 31. The core 4 comprises at least a bracket, a protective shell, and a power module and an electronic control module installed therein.

[0050] Reference Figure 7 After the integrated core body 4 is installed in the shell 31, an insertion cavity 310 is formed at the open end of the shell 31. The size of the insertion cavity 310 matches the size of the bottom 101 of the spliced ​​cigarette cartridge in Example 1, so that the spliced ​​body can be inserted into the insertion cavity 310.

[0051] See also Figure 7 and Figure 8 The bottom of the plug-in cavity 310 is the top of the integrated core 4, on which a pair of positive and negative output electrode contacts 51 and 52 for coupling the electronic control module are arranged. When the bottom 101 of the spliced ​​body composed of the first and second cigarette cartridges is inserted into the plug-in cavity 310, the single-connection electrical parts at the bottom of the first and second cigarette cartridges respectively abut against the positive and negative output electrode contacts 51 and 52 to draw electricity, forming a conductive loop.

[0052] See also Fig.10When the spliced ​​body composed of the first cigarette cartridge and the second cigarette cartridge is inserted into the plug-in cavity 310 of the host, the single-connected electrical parts at the bottom of the first cigarette cartridge and the second cigarette cartridge respectively abut the positive and negative output electrode contacts 51 and 52 in the plug-in cavity to obtain electricity; at the same time, a pair of conductive plugs on the splicing surface of the first cigarette cartridge and the second cigarette cartridge are plugged into each other to form two conductive paths, and then two parallel branches are formed between the two single-connected electrical parts 15 and 25, and the heating elements (heating wires) in the atomization components of the first cigarette cartridge and the second cigarette cartridge are respectively coupled to one of the branches. With this design, the power demand of the two cigarette cartridges can be met while only using a pair of output electrode contacts for power supply, which greatly simplifies the design and manufacturing cost of the host, and also enables the host originally equipped with a single cigarette cartridge to be suitable for the spliced ​​double cigarette cartridges in the present invention, meeting the needs of different flavors and reducing the consumption cost of users.

[0053] As a further preferred example, see the attached Figure 8 , the top of the integrated core body 4 is also provided with two magnetic adsorption units 53, 54. When the spliced ​​body composed of the first and second cigarette cartridges is inserted into the insertion cavity 310 of the host, the magnetic adsorption units 16, 26 at the bottom of the first and second cigarette cartridges and the magnetic adsorption units 53, 54 at the top of the integrated core body 4 attract each other, forming a magnetic adsorption connection, so that the cigarette cartridge can be stably connected to the host.

[0054] See also Figure 7 and Figure 8 In an example shown, an air inlet 32 ​​is provided on each side of the main body shell 31 (only one side is shown in the figure); at the same time, an air outlet 55 is provided at the top of the integrated core body 4, and the air inlet 32 ​​and the air outlet 55 are connected through an air flow channel provided in the core body 4, so that air can be sucked in from the air inlet 32 ​​and flow out from the air outlet 55 through the air flow channel, and then enter the air inlets 17 and 27 at the bottom of the first cigarette cartridge 1 and the second cigarette cartridge 2.

[0055] As a further preferred example, see the attached Fig. 9 , an airflow sensor 45 (preferably a microphone in this embodiment) is provided inside the integrated core 4, and its sampling head is located in the airflow channel in the core 4. Furthermore, a sealing ring 56 matching the shell 31 is provided at the top of the integrated core 4 to increase air tightness. At the same time, as part of the electronic control module, a control circuit coupled to the airflow sensor 45 is provided on the circuit board 42 located in the core 4, so that when the user makes a suction action and air flows through the airflow channel, the airflow sensor 45 can sense the airflow signal, and then the control circuit connects the power circuit, and outputs the working current through the output electrode contacts 51 and 52, so as to realize the automatic mode of sucking and using, which is more convenient to use and enhances the user experience.

[0056] As a further preferred example, the circuit board 42 is also provided with LED lamp beads; accordingly, see Figure 7 A light-transmitting portion 34 is provided on the host housing 31, so that a light indication can be given to indicate normal operation and other fault conditions.

[0057] As a further preferred example, the circuit board 42 is further provided with a vibrator 46, which can generate vibrations under the drive of the control circuit to give information prompts, such as the host starts to work, or the number of puffs of the user exceeds a certain limit.

[0058] See also Fig. 9 In this illustrative example, the power module includes a battery 43 and a small circuit board 44 configured with a power management circuit, and the small circuit board 44 is coupled to the charging interface 33. Figure 7 After assembly, the charging interface 33 is located at the other end of the host housing.

[0059] See also Figure 8 In this illustrative example, a snap-fit ​​mechanism 41 is provided on both sides of the integrated core 4, so that the integrated core 4 can be snap-fitted and installed in the shell 31.

[0060] See also Fig.11 and Fig.12 The flavor-adjustable electronic cigarette in this embodiment can be used after the first cigarette cartridge 1 and the second cigarette cartridge 2 are assembled into one body, the top is assembled into a mouthpiece 100, and the bottom 101 is inserted into the insertion cavity at the top of the main body shell 31.

[0061] As nicotine-containing electronic cigarettes are included in the scope of regulation, single-cartridge electronic cigarettes can only be made into tobacco flavors containing nicotine, which is difficult to meet consumers' demand for multiple flavors. However, the electronic cigarette with adjustable flavors in this embodiment can be filled with nicotine-containing e-liquid in one cartridge and flavoring liquid without nicotine in the other cartridge, thereby achieving the adjustment of multiple flavors.

[0062] On the other hand, the flavor-adjustable electronic cigarette of the present invention can also use the second type of electronic cigarette cartridges adapted to the above-mentioned host, that is, single-chamber cigarette cartridges. Its appearance is consistent with the appearance of the spliced ​​body formed by splicing the spliced ​​electronic cigarette cartridges, including an atomization component and a liquid storage chamber, with an air outlet and an air inlet at the top and bottom respectively, and a power connection electrode adapted to the output electrode contacts 51 and 52 at the bottom of the plug-in cavity at the bottom, which can also be used on the host in this embodiment.

[0063] Based on the above design, consumers who have purchased the main unit and the second type of electronic cigarette cartridge, i.e., the single-chamber cartridge, in this embodiment only need to purchase the spliced ​​cartridge in the aforementioned embodiment 1 again to adjust a variety of flavors, thereby greatly saving consumer costs and making the product of the present invention have a good market prospect.

[0064] The above embodiments are only used to help understand the method and core idea of ​​the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
