Description

Atomizer and atomizing body thereof

This application is based on the Chinese patent application with application number 202211205873.7 and application date September 30, 2022, and claims its priority. The entire content of the application is hereby introduced as a whole into this application.

Technical Field

The present application relates to the field of atomizers, and in particular to an atomizer and an atomizing body thereof.

Background technique

Atomizer is a device that heats and atomizes aerosol matrix to output aerosol. It includes an atomizer body and an atomizer head. The atomizer head includes a nozzle, an atomizer core and an aerosol matrix. The atomizer body supplies power to the atomizer head. When the atomizer head is working, the atomizer core converts electrical energy into heat energy, which acts on the aerosol matrix, causing the aerosol matrix to be heated and atomized to form an aerosol, which is output from the nozzle.

Most existing atomizers can only produce aerosols of one flavor. If you want to change the flavor, you need to replace the aerosol matrix in the atomizer core. There are also some atomizers that can change the flavor. Although they can change the flavor, when changing the flavor, you need to push the atomizer to slide or turn the shell by hand, which is inconvenient to operate.

Detailed ways

The present application is further described below in conjunction with the accompanying drawings and embodiments.

1 , the atomizer of some embodiments includes an atomizer body 100 and an atomizer head assembly 200. The atomizer head assembly 200 is disposed at one end of the atomizer body 100, and one end of the atomizer head assembly 200 has a nozzle 300. The atomizer body 100 provides electrical energy and control signals to the atomizer head assembly 200. When working, the heating core in the atomizer head assembly 200 converts electrical energy into thermal energy, heats the aerosol matrix, and the aerosol matrix is converted into aerosol and output from the nozzle 300.

FIG. 2 shows the external structure of the atomizing body 100 .

As shown in FIG2 , two output electrodes 105 are fixedly mounted at the front end 101 of the atomizing body 100 at a position off-center. The two output electrodes 105 are electrically connected to the battery inside the atomizing body 100 for supplying power to the atomizing head. The output electrodes 105 are preferably spring pins. When the spring pin electrodes are used, when they are in contact with the input electrodes on the atomizing head, the elastic force of the spring pins will make the contact between the electrodes more reliable.

The front end 101 of the atomizer body 100 is provided with an axial hole at the center, a rotating sleeve 103 is rotatably installed in the axial hole, a push shaft 102 is movably installed in the rotating sleeve 103, and a locking mechanism 106 is provided on the side of the atomizer body 100.

FIG. 3 shows the internal structure of the atomizing body 100 .

As shown in FIG3 , the trigger 106 is supported by a fulcrum 1061, and a connecting rod pair 1062 of the trigger 106 cooperates with a slider 107. When the trigger 106 is triggered, the slider 107 is driven to slide to the right by the connecting rod pair 1062. The right direction is the direction away from the axis of the installation push shaft 102.

The slider 107 is formed with a second rack 1071 (see FIGS. 4 and 5 ), which slides along with the slider 107 and is called a sliding rack. The push shaft 102 is formed with a first rack 112, which meshes with a first gear 111, and the first gear 111 is mounted on the main body of the atomizer through a support shaft 110.

4 and 5, the first gear 111 is provided with a second gear 1111 in parallel, and the second gear 1111 is meshed with the second rack 1071. The first gear 111 and the second gear 1111 are both mounted on the support shaft 110 and can be linked. The first gear 111 and the second gear 1111 are preferably composed of the same double gear.

The combination of the first gear 111, the second gear 1111, the first rack 112 and the second rack 1071 constitutes a linkage mechanism between the trigger 106 and the push shaft 102. When the trigger 106 is triggered, the slider 107 drives the second rack 1071 to slide to the right in FIG. 3, the second rack 1071 drives the second gear 1111 to rotate, the second gear 1111 drives the first gear 111 to rotate synchronously, and the first gear 111 drives the first rack 112 to move to the upper side in FIG. 3, so that the push shaft 102 moves upward, and the upward movement of the push shaft 102 is the outward push movement of the push shaft.

3 and 4, a connecting rod 109 is installed on the top of the slider 107 through a pin 108, and a pawl 1091 is formed on the connecting rod 109. A ratchet 1031 is formed on the lower end of the rotating sleeve 103, and the pawl 1091 is meshed with a tooth position of the ratchet 1031. A torsion spring 1092 is installed on the pin 108, and two spring arms of the torsion spring 1092 are respectively pressed and matched with the connecting rod 109 and the slider 107, so that the pawl 1091 and the ratchet 1031 are reliably meshed.

The connecting rod 109, the pawl 1091, the torsion spring 1092 and the ratchet 1031 constitute a linkage mechanism between the trigger 106 and the rotating sleeve 103. When the trigger 106 is triggered, the slider 107 drives the connecting rod 109 to slide to the right in FIG. 3, the connecting rod 109 drives the pawl 1091 to move rightward, and the pawl 1091 drives the ratchet 1031 to rotate one tooth position, thereby causing the rotating sleeve 103 to rotate a certain angle.

The above two linkage mechanisms are both connected to the button 106 through the slider 107. When the button 106 is pulled, the push shaft 102 and the rotating sleeve 103 are linked.

3 and 4 , a compression spring 113 and a stop pin 114 are disposed at the end of the push shaft 102 away from the atomizer head assembly. One end of the compression spring 113 is crimped with the stop pin 114 , and the other end is crimped with the body of the atomizer body, exerting a downward elastic force on the push shaft 102 .

The compression spring 113 and the stop pin 114 constitute a reset device for the push shaft 102 and the trigger 106. When the finger leaves the trigger 106, the elastic force of the compression spring 113 causes the push shaft 102 to move downward in FIG. 3 to reset. The downward movement of the push shaft 102 is the retraction movement of the push shaft 102, which is also called the pull-back movement. In short, it is the opposite movement of the push shaft's outward movement. The movement of the push shaft 102 is transmitted to the trigger 106 through the linkage mechanism between the push shaft 102 and the trigger 106, so that the trigger 106 is reset.

The pawl 1091 will also be reset with the reset of the trigger 106. Specifically, during the reset of the trigger 106, the slider 107 will move to the left in FIG. 3, and the slider 10 drives the connecting rod 109 to move to the left, so that the pawl 1091 passes over a tooth of the ratchet 1031 and meshes with the next tooth position of the ratchet 1031.

FIG6 shows the structure of the atomizer head assembly 200. An axial hole is provided at the center of the atomizer head assembly 200, and a connecting sleeve 203 is fixedly installed in the axial hole, and an end of the connecting sleeve 203 has end teeth. The atomizer head assembly 200 is configured with five monomer atomizer heads 201, which are evenly distributed on the same circumference with the rotation center of the atomizer head assembly 200 as the center. Each monomer atomizer head 201 is provided with two input electrodes 202. The aerosol matrix contained in the five monomer atomizer heads 201 is different, and aerosols of different flavors can be produced.

As other embodiments, the number of the monomer atomizer heads 201 of the atomizer head assembly 200 may also be three, four, six, seven, etc., and the present application does not limit the number of the monomer atomizer heads 201. The aerosol substrates contained in the monomer atomizer heads 201 may be the same or different, or the aerosol substrates contained in some monomer atomizer heads 201 may be the same, while the aerosol substrates contained in other monomer atomizer heads 201 may be different.

7, the push shaft 102 of the atomizing body 100 is assembled in the connecting sleeve 203 of the atomizing head assembly 200, and the push shaft 102 can rotate relative to the connecting sleeve 203. The rotating sleeve 103 of the atomizing body 100 is engaged with the connecting sleeve 203 through the end teeth of the end. A threaded hole is formed at the end of the push shaft 102, and the screw 205 is threadedly connected with the threaded hole to fix the atomizing head assembly 200 to the push shaft 102.

The combination of the above-mentioned atomizing body 100 and the atomizing head assembly 200 constitutes a multi-flavor atomizer. The finger can easily switch the flavor by pressing the trigger 106. The principle is: when the trigger 106 is pressed once, the trigger 106 drives the push shaft 102 and the rotating sleeve 103 to move together through the linkage mechanism, and the push shaft 102 drives the atomizing head assembly 200 to move to the upper side in Figure 7, so that the input electrode of the current working monomer atomizing head is disengaged from the output electrode of the atomizing body; the rotating sleeve 103 drives the atomizing head assembly 200 to rotate one tooth position, so that the current working monomer atomizing head is staggered with the output electrode of the atomizing body, and the next monomer atomizing head is aligned with the output electrode of the atomizing body; after the finger releases the trigger 106, under the thrust of the compression spring 113, the push shaft 103 and the trigger 106 are reset, and the push shaft 102 drives the atomizing head assembly 200 to move downward and reset, and the input electrode of the next monomer atomizing head is in contact with the output electrode of the atomizing body, thereby completing the flavor conversion. In this process, the pawl is also reset and meshes with the next tooth position of the ratchet wheel. The above has completed a taste conversion, and each time the trigger 106 is pulled once, a taste conversion can be achieved.

Affected by the processing error of parts, etc., after the flavor conversion of the above-mentioned multi-flavor atomizer, the input electrode on the atomizer head and the output electrode on the atomizer body may not be fully aligned. To solve this problem, referring to Figures 2 and 6 again, a first magnet 204 is further provided at the rear end of the atomizer head assembly 200, that is, the end of the atomizer head assembly 200 facing the atomizer body 100, corresponding to each monomer atomizer head 201, and a second magnet 104 is provided at the front end of the atomizer body 100. The second magnet 104 cooperates with the first magnet 204, and uses the principle of opposites attracting and likes repelling to assist the input electrode of the monomer atomizer head to align with the output electrode of the atomizer body.

Further referring to FIG. 5 , the second rack 1071 is formed on the slider 107, the slider 107 is provided with a first slot 1073 and a second slot 1072 intersecting vertically, the second rack 1071 is formed on the hole wall of the second slot 1072, the first rack and the first gear 111 are arranged in the first slot 1073, and the second gear 1111 is arranged in the second slot 1072. This structure, in which the two gears are built into the slider 107, achieves the beneficial effects of compact structure and small volume.

8, the atomizer head assembly 200 is composed of a cartridge assembly 210, a single atomizer head 201 and a nozzle assembly 220. The single atomizer head 201 is inserted into the cartridge assembly 210 and is detachable. After the nozzle assembly 220 is removed, the single atomizer head 201 can be replaced, and multiple single atomizers 201 can be loaded at one time.

9, the monomer atomizing head 201 includes an upper cover 2011, an atomizing tube 2012, a matrix container 2013, a liquid-conducting medium 2014, a heating core 2015, a lower cover 2016 and an input electrode 2017. The aerosol matrix is contained in the matrix container 2013, and the heating core 2015 is electrically connected to the input electrode 2017. After power is turned on, the heating core generates heat, and the aerosol matrix enters the heating core through the liquid-conducting medium 2014. After being heated, it is converted into an aerosol and output through the atomizing tube 2012. In this embodiment, the liquid-conducting medium 2014 adopts liquid-conducting cotton. As other embodiments, the liquid-conducting medium can also adopt porous ceramics, etc.

As another embodiment, a gear may be fixedly provided at the inner end of the trigger 106, and the trigger 106 is installed on the atomizing body through the core shaft of the gear, and the gear is directly or indirectly meshed with the rack 112 on the push shaft 102, so as to form a linkage mechanism between the trigger 106 and the push shaft 102. When the trigger 106 is triggered, the gear at the inner end of the trigger 106 rotates, and the gear drives the rack 112 to move, thereby driving the push shaft 102 to move. In this embodiment, the linkage mechanism between the trigger 106 and the rotating sleeve 103 is the same as that in the above embodiment.

As another embodiment, the reset device of the trigger 106 can also be a torsion spring, which is arranged at the fulcrum of the trigger. Since the trigger is linked with the push shaft, the push shaft can also be reset by the torsion spring.

In the embodiment of FIG. 4 , in the linkage mechanism between the trigger and the rotating sleeve, a torsion spring 1092 is used as an elastic member to press the pawl 1091 toward the ratchet 1031 so that the pawl 1091 reliably engages with the ratchet 1031. Those skilled in the art should understand that a tension spring is provided between the side of the connecting rod 109 facing the ratchet 1031 and the slider 107, or a compression spring is provided between the side of the connecting rod 109 facing away from the ratchet 1031 and the slider 107, which can also achieve the effect of pressing the pawl 1091 toward the ratchet 1031 so that the pawl 1091 reliably engages with the ratchet 1031.
