[0027] Preferably, the bracket is provided with at least a plurality of partition blocks in the communicating chamber, and oil guide holes connected to the oil guide cotton are provided between the plurality of partition blocks.
[0028] By adopting the above technical solution, due to the setting of the dividing blocks, when the smoke oil flows into the connecting chamber, multiple dividing blocks can block the smoke oil to prevent the smoke oil from contacting the oil-conducting cotton over a large area, so as to achieve the effect of controlling the oil intake speed, thereby minimizing the smoke oil dripping from the air inlet hole in the atomization chamber due to saturation of the oil-conducting cotton.

In this design, the bracket is located at the lower side of the oil storage chamber, that is, the atomization chamber is located at the lower side of the oil storage chamber as a whole, so that the components in the atomization chamber will not always contact with the smoke oil, so as to avoid long-term immersion in the smoke oil to cause harmful substances to be dispersed into the smoke oil and inhaled by the human body, thereby helping to improve the health and safety performance of the electronic atomization device when used;

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0047] The present application embodiment discloses a pre-filled oil smoke cartridge. Figures 1 to 8The pre-filled oil smoke cartridge includes a shell 1 and a base 2. Specifically, one side of the shell 1 is set as a cigarette holder for people to smoke. A smoke outlet is set at the cigarette holder of the shell 1, and the other side of the shell 1 is set with an opening. A bracket 3 is set in the middle position inside the shell 1. The side of the bracket 3 is sealed and connected with the inner side of the shell 1, so that the upper side of the bracket 3 and the upper side of the shell 1 form a sealed chamber, that is, an oil storage chamber 11. An atomization chamber 31 is set inside the bracket 3. The smoke oil in the oil storage chamber 11 will flow into the atomization chamber 31 for atomization. The top and bottom surfaces of the bracket 3 are respectively provided with outlets. The air hole 33 and the air inlet hole 32 are connected to the atomizing chamber 31 respectively. The air flow can enter the atomizing chamber 31 from the air inlet hole 32 and then flow out from the air outlet hole 33. An air outlet pipe 12 is arranged at the top position inside the shell 1. One side of the air outlet pipe 12 is fixedly sealed and connected to the smoke outlet of the shell 1, and the other end extends into the air outlet hole 33. In this embodiment, the inner wall of the air outlet hole 33 is arranged in a stepped shape, and the outer side wall of the air outlet pipe 12 is sealed and abutted against the inner wall of the air outlet hole 33. A heating net 34 and oil guide cotton 35 are arranged in the atomizing chamber 31. The guide cotton 35 is provided to guide the smoke into the atomizing chamber 31. The oil cotton 35 is arranged close to the side wall of the atomizing chamber 31, and is connected to the heating network 34 on the side of the oil-conducting cotton 35 away from the connection between the oil-conducting cotton 35 and the atomizing chamber 31. At the same time, a connecting cavity 36 is arranged on the outer side of the bracket 3, and the connecting cavity 36 is arranged on one side of the oil-conducting cotton 35. The connecting cavity 36 is connected to the oil storage chamber 11, and the connecting cavity 36 is provided with an oil guide hole 313 on the side close to the oil-conducting cotton 35, so that the smoke oil can enter the connecting cavity 36 from the oil storage chamber 11, and finally flow into the oil-conducting cotton 35 through the oil guide hole 313 to be atomized. The base 2 is arranged on one side of the opening of the shell 1, and the base 2 is used to seal the opening of the shell 1. The base 2 is provided with an air inlet channel 21, which is connected to the air inlet hole 32. The base 2 is provided with an electrode 22, which is electrically connected to the heating network 34. In this design, the atomization structure of the smoke oil is at the bottom of the oil storage chamber 11, so the structure except the oil guide cotton 35 will not be in contact with the smoke oil for a long time, so as to avoid the substances harmful to the human body from being dispersed into the smoke oil and inhaled by the human body due to long-term immersion in the smoke oil, thereby helping to improve the health and safety performance of the electronic atomization device when it is used.
[0048] In this embodiment, the base 2 and the shell 1 are installed by a snap-fitting method, and the base 2 and the bracket 3 are also snap-fitting methods, for example, through snap-fitting holes and snap-fitting blocks, and other methods can also be used. Therefore, the entire cigarette cartridge can be divided into three parts: the shell 1, the bracket 3 and the base 2. The assembly process of the cigarette cartridge is simple and convenient, which reduces the assembly cost of the cigarette cartridge.
[0049] The heating net 34 adopts a flat structure, and the heating net 34 and the oil guide cotton 35 are arranged in abutment. Compared with the heating net 34 in a rolled shape, the flat heating net 34 has a larger contact area with the oil guide cotton 35, so that more smoke oil can be atomized at the same time. At the same time, the airflow impacts the entire mesh heating wire over a large area, and the user feels the fullness of the smoke impacting the mouth, which helps to improve the experience during inhalation. In order to facilitate the installation of the heating net 34, a positioning column 311 is provided in the atomization chamber 31. The positioning column 311 is cylindrical. There are two positioning columns 311, and the two positioning columns 311 are arranged at intervals in the horizontal direction. The oil guide cotton 35 is arranged between the two positioning columns 311. Positioning holes 341 are provided on both sides of the heating net 34. The positioning holes 34 The cross section of the hole is circular for the insertion of the positioning column 311. In order to avoid the deviation of the heating net 34, a fixed silica gel 312 is also arranged in the atomizing chamber 31. The fixed silica gel 312 is arranged in a U shape as a whole. The two sides of the U shape of the fixed silica gel 312 are tightly abutted against the two sides of the heating net 34 respectively. The U-shaped inner side of the fixed silica gel 312 allows air flow to pass through. At the same time, the side of the fixed silica gel 312 away from the heating net 34 extends out of the atomizing chamber 31 to achieve the clamping and fixing of the fixed silica gel 312. Therefore, through the cooperation of the positioning column 311 and the positioning hole 341 and the setting of the fixed silica gel 312, the heating net 34 can be fixed at a predetermined position in the atomizing chamber 31, thereby avoiding the deviation of the heating net 34 and the reduction of the contact area with the oil guide cotton 35.
[0050] In order to make the electrical connection between the electrode 22 on the base 2 and the heating network 34 more stable, a mounting groove 37 is provided at the bottom of the bracket 3, and the bottom of the mounting groove 37 extends in the direction away from the base 2. At the same time, two metal wires 342 are provided on the heating network 34, and the two metal wires 342 are respectively connected to the positive and negative electrodes of the heating network 34. One end of the metal wire 342 away from the heating network 34 extends out of the atomization chamber 31 and is bent into a U shape so as to be inserted into the mounting groove 37. Therefore, when the base 2 is installed, the electrode 22 on the base 2 will be inserted into the mounting groove 37, and the electrode 22 will squeeze the metal wire 342 tightly against the side wall of the mounting groove 37, so that the metal wire 342 is not easy to slip out of the mounting groove 37, which can make the insertion of the metal wire 342 more stable, thereby improving the connection stability between the electrode 22 and the heating network 34.
[0051] In order to further completely atomize the smoke oil in the oil storage chamber 11, a guide chamber 39 is provided on the upper side of the bracket 3. The guide chamber 39 extends toward the side away from the oil storage chamber 11. The guide chamber 39 is provided on the side of the upper side of the bracket 3 away from the connecting chamber 36, and two guide chambers 39 are provided on the side of the bracket 3 away from the connecting chamber 36. The two guide chambers 39 are respectively connected to the connecting chamber 36, so the smoke oil in the oil storage chamber 11 can flow from the guide chamber 39 to the connecting chamber 36. When the remaining smoke oil in the oil storage chamber 11 is small, no matter what posture the user takes to inhale, the cigarette cartridge is in a tilted state as a whole, and the smoke oil in the oil storage chamber 11 will flow from the guide chamber 39 to the connecting chamber 36 or directly flow into the connecting chamber 36, so as to further use up the smoke oil in the cigarette cartridge, thereby increasing the actual number of inhalations of the cigarette cartridge.
[0052] Since the oil storage chamber 11 needs to be filled with oil in advance during the actual production process of the cigarette cartridge, and the shell 1 is in an inverted state during the oil filling, the air outlet pipe 12 needs to be inserted into the air outlet hole 33 of the bracket 3 during the installation process of the bracket 3. During this process, when the air outlet pipe 12 just contacts the side wall of the air outlet hole 33, the oil storage chamber 11 will be in a sealed state. During the movement of the bracket 3, the gas in the oil storage chamber 11 will be further compressed, which will increase the difficulty of moving the bracket 3. Therefore, an air flow channel 4 is provided on the side wall of the bracket 3. One end of the air flow channel 4 will be connected to the side wall of the guide cavity 39 to be connected to the oil storage chamber 11, and the other end of the air flow channel 4 will penetrate the bracket 3. Therefore, during the installation process of the bracket 3, the air flow in the oil storage chamber 11 can flow out from the air flow channel 4, so the air pressure in the oil storage chamber 11 is in a state that is equal to the atmospheric pressure. Therefore, the installation of the bracket 3 can be more convenient during the installation process, and the sealing connection between the air outlet pipe 12 and the air outlet hole 33 can be better.
[0053] In order to improve the sealing performance between the inner wall of the shell 1 and the bracket 3 and the base 2, the following configurations are also provided. First, a first sealing ring 38 is provided on the side of the bracket 3 close to the oil storage chamber 11. The first sealing ring 38 is made of silicone and is provided in an annular shape. In this embodiment, in order to seal the connecting chamber 36, the first sealing ring 38 is avoided. When the bracket 3 is installed in the shell 1, the outer wall of the first sealing ring 38 will fully abut against the inner wall of the shell 1 to improve the sealing performance and prevent the smoke oil from flowing out of the gap between the bracket 3 and the shell 1. Second, around the base 2, a sealing ring 38 is provided. A second sealing ring 23 is arranged on the side, and the second sealing ring 23 is also made of silicone material. The second sealing ring 23 is arranged on the side of the base 2 close to the bracket 3. The outer wall of the second sealing ring 23 is used to abut against the inner wall of the shell 1, and when the bracket 3 is snapped on the base 2, the side wall of the second sealing ring 23 will block the side of the air flow channel 4 away from the oil storage chamber 11 to prevent the oil in the oil storage chamber 11 from leaking from the air flow channel 4 after the cigarette cartridge is assembled; through the action of the first sealing ring 38 and the second sealing ring 23, the oil can be prevented from flowing out of the oil storage chamber 11 as much as possible, thereby improving the sealing performance of the cigarette cartridge.
[0054] In addition, in the present embodiment, a partition block 5 is provided on the side wall of the connecting cavity 36. The partition block 5 is provided on the side wall where the connecting cavity 36 is connected to the oil-conducting cotton 35. The partition block 5 is in the shape of a rectangular block. There are multiple partition blocks 5, and the multiple partition blocks 5 are arranged at equal distances in the horizontal direction. At the same time, multiple oil guide holes 313 are also provided, and the multiple oil guide holes 313 are respectively arranged between two adjacent partition blocks 5. Through the setting of the partition block 5, the smoke oil can be blocked, the oil intake speed can be controlled, and the smoke oil can be prevented from directly entering the oil-conducting cotton 35 all at once, causing the oil-conducting cotton 35 to become saturated and leak oil.
[0055] The implementation principle of a pre-filled smoke cartridge in the embodiment of the present application is as follows: due to the setting of the connecting chamber 36, the smoke oil can enter the atomization chamber 31 through the connecting chamber 36. With this design, the entire atomization structure is located below the oil storage chamber 11 and is not immersed in the oil storage chamber 11, so it is possible to avoid long-term immersion in the smoke oil, which causes substances harmful to the human body to be dispersed into the smoke oil and inhaled by the human body, thereby helping to improve the health and safety performance of the electronic atomization device when used.
[0056] The utility model further provides an electronic atomization device, including the above-mentioned cigarette cartridge. The electronic atomization device of this embodiment also has the above-mentioned beneficial effects, which will not be described one by one here.
[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
