Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a power supply device and an aerosol generating device. Background Art

[0002] The smoke from burning cigarettes contains harmful substances such as tar, which can cause great harm to the human body if inhaled for a long time. In order to overcome the harmful substances produced by burning cigarettes, low-harm cigarette substitutes such as e-cigarettes with e-liquid and heat-not-burn e-cigarettes have emerged.

[0003] Traditional electronic cigarettes include battery cells, which are the source of energy for electronic atomization devices. The heat required for atomization of the e-liquid is generated through the conversion of electrical energy in the battery cells. The battery cells produce harmful substances during use. If these harmful substances are mixed in the gas and inhaled by the user, they will pose a potential hazard to the user's health. Summary of the invention

[0004] Based on this, in order to address the above problems, it is necessary to provide a power supply device and an aerosol generating device.

[0006] A shell, wherein the shell is a hollow shell;

[0008] A bracket is arranged in the shell and enclosed with the inner surface of the shell to form a battery compartment for accommodating the battery, and an air leakage channel is provided through the bracket, one end of the air leakage channel is communicated with the battery compartment, and the other end of the air leakage channel is used to communicate with the atomization chamber of the atomization device;

[0009] A filter element is disposed between the battery compartment and the atomization chamber, and is used for filtering the gas flowing through the air leakage channel.

[0010] In the above-mentioned power supply device, the batteries in the battery compartment may generate heat and harmful gases during use. The accumulation of harmful gases will also increase the air pressure in the battery compartment. In view of this, the present application sets a gas discharge channel on the bracket. The gas discharge channel can discharge the heat and gas in the battery compartment in time, thereby effectively eliminating the high temperature and high pressure environment in the battery compartment, and preventing the electrolyte in the battery from volatilizing under the action of high temperature and high pressure and producing harmful substances through chemical reactions. At the same time, in order to prevent the harmful substances in the battery compartment from flowing into the atomization chamber of the atomization device from the battery compartment through the gas discharge channel along with the gas, the present application adds a filter for filtering the gas flowing through the gas discharge channel, which can filter out harmful substances and ensure that the gas finally inhaled by the user does not contain harmful substances, thereby maintaining the health of the user.

[0011] In one embodiment, the filter is disposed in the battery compartment and between the bracket and the battery, and the filter covers the air leakage channel and allows the gas in the battery compartment to flow through. Such a configuration enables the gas in the battery compartment to be filtered by the filter before flowing into the air leakage channel, ensuring that harmful substances can be effectively filtered out by the filter.

[0012] In one embodiment, the filter element is disposed in the air leakage channel and is capable of allowing the gas in the battery compartment to flow through.

[0013] In one embodiment, the power supply device further includes a circuit board assembly disposed in the housing, and the battery is electrically connected to the atomization device via the circuit board assembly.

[0014] In one embodiment, the circuit board assembly is disposed in the bracket, and the air leakage channel penetrates both the circuit board assembly and the bracket.

[0015] In one embodiment, the bracket includes a first bracket and a second bracket stacked with the first bracket, the second bracket and the inner surface of the shell are combined to form the battery compartment, the circuit board assembly is arranged between the first bracket and the second bracket, and the air leakage channel simultaneously passes through the first bracket, the circuit board assembly and the second bracket.

[0016] In one embodiment, the circuit board assembly includes a circuit board, an electrode pin and a conductive member, the conductive member and the electrode pin are electrically connected to opposite sides of the circuit board, the conductive member is partially inserted into the second bracket to be electrically connected to the battery, and the electrode pin is partially inserted into the first bracket to be electrically connected to the atomization device.

[0017] In one embodiment, the filter is disposed in the battery compartment and between the second bracket and the battery. The filter covers the air leakage channel and allows the gas in the battery compartment to flow through.

[0018] In one embodiment, the circuit board assembly includes a circuit board and an electrode ejector electrically connected to the circuit board, and the electrode ejector portion is inserted through the bracket for electrical connection with the atomization device.

[0019] In one embodiment, the filter element is a one-way filter element.

[0020] In one embodiment, the filter element includes at least one of an activated carbon filter element, a carbon molecular sieve filter element, and a diatomaceous earth filter element. The activated carbon filter element, the carbon molecular sieve filter element, and the diatomaceous earth filter element can absorb and filter harmful gases without affecting airflow and suction resistance.

[0021] In one embodiment, the filter element is a porous filter element with filtering function.

[0022] The present application also relates to an aerosol generating device, which includes an atomizing device and a power supply device as described in any of the above embodiments, wherein the power supply device is electrically connected to the atomizing device. The aerosol generating device may be a split electronic cigarette, that is, the atomizing device may refer to a cigarette cartridge, and the power supply device may refer to a cigarette rod with a power supply. For users, the atomizing device and the power supply device can be easily disassembled and replaced. The aerosol generating device can also be considered as an integrated electronic cigarette, that is, a disposable electronic cigarette, in which case the atomizing device is built into the shell.

[0023] In one embodiment, the atomizing device is configured to be separable from the power supply device under the action of an external force. For example, in one embodiment, when the aerosol generating device is a replaceable cartridge electronic cigarette, the atomizing device can be directly pulled out from one end of the power supply device, that is, the cigarette cartridge is pulled out from one end of the cigarette rod. For example, in another embodiment, when the aerosol generating device is a disposable electronic cigarette, that is, an integrated electronic cigarette, and the atomizing device is built into the shell, a special fixture can be used to separate the atomizing device from the power supply device.

[0024] The above-mentioned aerosol generating device may be provided with the power supply device described in the above-mentioned embodiments, and therefore, it also includes at least the following beneficial effects: the battery in the battery compartment of the power supply device may generate heat and harmful gases during use, and the accumulation of harmful gases will also increase the air pressure in the battery compartment. In view of this, the present application sets a venting channel on the bracket. The venting channel can timely release the heat and gas in the battery compartment, thereby effectively eliminating the high temperature and high pressure environment in the battery compartment, and preventing the electrolyte in the battery from volatilizing under the action of high temperature and high pressure and producing harmful substances through chemical reactions. At the same time, in order to prevent the harmful substances in the battery compartment from flowing into the atomizing chamber of the atomizing device from the battery compartment through the venting channel along with the gas, the present application adds a filter for filtering the gas flowing through the venting channel, which can filter out harmful substances, ensuring that the gas finally inhaled by the user does not contain harmful substances, and maintaining the health of the user.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The present application provides a power supply device 11, which is used to supply power to the atomizing device 12 of the aerosol generating device 10. Among them, the atomizing chamber 121 of the atomizing device 12 can convert the atomizing medium into an aerosol that can be inhaled by the user. The power supply device 11 includes a shell 100, a battery 200, a bracket 300 and a filter 400. The shell 100 is roughly cylindrical and hollow. The bracket 300 is arranged in the shell 100 and encloses the inner surface of the shell 100 to form a battery compartment 110 for accommodating the battery 200, and the battery 200 is used to supply power to the atomizing device 12. The bracket 300 is penetrated by a gas leakage channel 330, one end of the gas leakage channel 330 is connected to the battery compartment 110, and the other end of the gas leakage channel 330 is used to communicate with the atomizing chamber 121 of the atomizing device 12.
