There are various types of non-combustion type aspirators, such as a method of atomizing a liquid to generate an aerosol and a method of directly heating a cigarette, depending on the difference in the heating target and the like. The present invention is not limited to the non-combustion type suction device of a specific type, but in the present embodiment, the description will be made by exemplifying the non-combustion type suction device of the type called the low temperature heating method. The low-temperature heating method is a method in which a liquid is heated by using electric power supplied from a battery pack, and a user inhales atomized aerosol through a cigarette capsule filled with cigarettes. Of course, the present invention can also be applied to a high-temperature heating type non-combustion type suction device.

The cartomizer 31 sprays the aerosol generated by heating the liquid by the heater toward the suction unit 4. A capsule (not shown) filled with cigarettes is housed in the suction unit 4, and the aerosol in which the liquid is atomized goes to the suction side through the capsule. The user sucks the aerosol containing the component derived from the cigarette through the suction unit 4.

The non-combustion type suction device 1 is turned on / off by pressing the circular button portion 201 (operation portion). As will be described later, the battery pack 2 according to the present embodiment has a barometric pressure sensor. When the barometric pressure sensor detects a barometric pressure difference equal to or higher than the threshold value (for example, 100 Pa or higher), in other words, when it is detected that the non-combustion suction device 1 has been sucked, the battery pack 2 operates to the heater. Power is supplied. A detailed operation example of the non-combustion type suction device 1 will be described later.

In the non-combustion type suction device 1 according to the present embodiment, the remaining capacity of the battery pack 2 is visually notified when the non-combustion type suction device 1 is started. For example, a circular translucent member is arranged around the button portion 201. Further, the battery pack 2 has a light emitting element. The light emitting element emits light in a color corresponding to the remaining capacity of the battery pack 2, and the light emitting color when the light emitting element emits light is visually recognized by the user via the transmission member.

[About the moisture intrusion prevention structure]
Next, the moisture intrusion prevention structure of the battery pack 2, which is one of the features of the present invention, will be described. The moisture intrusion prevention structure of the battery pack 2 prevents moisture from entering the space in which the first circuit board 205 and the battery cell 203 are held (hereinafter, appropriately referred to as a holding space such as a battery cell) in the outer case 202. It is a structure. Moisture that can enter the holding space such as a battery cell includes liquid leaked from the cartridge case 3, water liquefied by cooling the atomized liquid in the cartridge case 3 or the battery pack 2, and saliva of the user. is assumed.

FIG. 7 is a diagram showing an example of internal configuration (cross section in the axial direction) near the tip of the battery pack 2 on the connection side. In FIG. 7, the O-ring 208 and the packing 210 are not shown in order to facilitate understanding of the moisture intrusion prevention structure according to the present embodiment. In the battery pack 2, a holding space SP such as a battery cell is formed in which the first circuit board 205 and the battery cell 203 (not shown in FIGS. 7 and 8) are held.

In FIG. 7, the intrusion route of water into the holding space SP such as a battery cell is indicated by a dotted arrow. As a path for moisture to enter, the moisture that has entered through the air suction hole 209D is transmitted on the surface of the second circuit board 211, and the battery cell or the like holding space SP is transmitted from between the substrate holder 209 and the second circuit board 211. There is a route to invade. As another entry route of water, there is a route in which water is transmitted through the space formed between the connecting member 207 and the substrate holder 209 and enters the holding space SP such as a battery cell.

As shown in FIG. 8, in the battery pack 2 according to the present embodiment, the packing 210 is interposed between the outer peripheral portion of the second circuit board 211 and the inner peripheral surface of the step 209E of the substrate holder 209. .. The packing 210 prevents moisture from entering the holding space SP such as a battery cell from between the substrate holder 209 and the second circuit board 211. Further, in the battery pack 2 according to the present embodiment, the O-ring 208 is interposed between the connecting member 207 and the outer peripheral surface of the step 209E of the substrate holder 209. The O-ring 208 prevents moisture from being transmitted through the space formed between the connecting member 207 and the substrate holder 209 and invading the holding space SP such as a battery cell. As described above, since the intrusion of water into the holding space SP such as the battery cell is prevented, the battery cell 203 and the first circuit board 205 can be protected.

In the present embodiment, the barometric pressure sensor 211C is mounted at a position offset from the air suction hole 209D. Specifically, the barometric pressure sensor 211C is mounted at a position separated from the air suction hole 209D by a predetermined value or more. With such a configuration, it is possible to prevent the moisture that has entered from the air suction hole 209D from dripping and directly hitting the barometric pressure sensor 211C. Therefore, the barometric pressure sensor 211C can be protected. When the barometric pressure sensor 211C has a waterproof function, the mounting position of the barometric pressure sensor 211C can be set to an arbitrary position.

[Battery pack assembly method]
Next, the method of assembling the battery pack 2 according to the embodiment will be described. First, the translucent member 206 is inserted into the outer case 202. The light-transmitting member 206 is positioned by being hooked (locked) to the outer case hole 202A of the outer case 202 by the wall portion 206C of the light-transmitting member 206. In such a state, the outer case hole 202A and the translucent member hole 206B form a hole leading to the inside and outside of the outer case 202.

Next, the battery cell 203 is stored in the battery cell storage unit 204I of the holder 204. Specifically, the battery cell 203 to which the tab 212 is attached and the insulating paper 215 is attached is stored in the battery cell storage unit 204I. The stored battery cell 203 is fixed to the battery cell storage portion 204I from the insulating tape 217.

Further, the USB board 214 held by the stopper 213 is housed in the holder 204. By connecting the FPC 216 to each of the USB board 214 and the first circuit board 205, both are electrically connected. Further, by connecting the FPC 218 to the first circuit board 205 and the second circuit board 211, both are electrically connected. The left and right ends of the stopper 213 are claw-shaped, and are fitted into the holes 204F provided on the left and right side surfaces of the holder 204 on the tip end side.

Next, the end portion of the first circuit board 205 is placed on the connecting surface 204J, the end surface 241A, and the end surface 241B. Further, the second circuit board 211 is arranged at the tip of the holder connection portion 204G. Then, the connection side of the holder 204 is inserted into the outer case 202 from the open end on the tip side of the outer case 202. Then, the holder 204 is inserted into the outer case 202 while the wall portion 242A is guided by the recess 253A of the translucent member 206 and the wall portion 242B is guided by the recess 253B of the translucent member 206. As described above, since the recess 253A and the recess 253B have a guide function, it is possible to prevent the holder 204 from being inserted into the outer case 202 in the wrong direction.

The holder 204 is slid and inserted into the outer case 202 while the tip surface of the wall portion 242A is in contact with the recess 253A. Further, the holder 204 is slid and inserted into the outer case 202 while the tip surface of the wall portion 242B is in contact with the recess 253B. That is, the holder 204 is press-fitted into the outer case 202 so as to oppose the drag generated at the contact portion between the wall portion 242A and the recess 253A and the contact portion between the wall portion 242B and the recess 253B. Further, as the holder 204 is press-fitted, the upper end portion of the first circuit board 205 is pressed by the convex portion 252A and the convex portion 252B.

When the holder 204 is press-fitted into the outer case 202 by a certain amount or more, the tip end surface of the outer case 202 comes into contact with the side surface portion 204D of the holder 204, and the movement of the holder 204 is restricted. In the outer case 202, the inner peripheral surface of the outer case 202 interferes with the outer side of the holder 204 and the outer side of the translucent member 206. Further, the holder 204 and the translucent member 206 interfere with each other. When the movement of the holder 204 is restricted, the holder connection portion 204G is exposed to the outside from the open end on the connection side of the outer case 202.

Then, the board holder 209 in which the packing 210 is housed is connected to the holder connection portion 204G. Specifically, the claw portion 204H of the holder 204 is fitted into the claw portion fitting hole portion 209F of the substrate holder 209, whereby the holder 204 and the substrate holder 209 are connected. The packing 210 is crushed by the peripheral edge of the connection side main surface of the second circuit board 211 and the inner peripheral surface of the step 209E by the force generated at the time of fitting, and the waterproof function of the packing 210 is exhibited.

Next, the O-ring 208 is placed on the step 209E of the board holder 209. Then, the tip end side of the connecting member 207 is connected to the connecting side open end of the outer case 202, and the substrate holder 209 is covered with the connecting member 207. The O-ring 208 is crushed by the outer peripheral surface of the step 209E and the tip end surface of the first connecting member 207A by the force generated at the time of connection, and the waterproof function of the O-ring 208 is exhibited.

Finally, the button portion 201 is inserted into the outer case hole portion 202A and the translucent member hole portion 206B. The button portion 201 is locked at a predetermined position.

By assembling the battery pack 2 as described above, each configuration is integrated (see FIG. 9). The method of assembling the battery pack 2 described above is an example, and the order of some steps may be changed.

[Operation example of non-combustion type suction device]
Next, an operation example of the non-combustion type suction device 1 according to the present embodiment will be described. When the button unit 201 is pressed, the controller mounted on the first circuit board 205 acquires the atmospheric pressure from the atmospheric pressure sensor 211C. The atmospheric pressure sensor 211C is, for example, a space partitioned by the substrate holder 209, the second circuit board 211, and the packing 210, and detects the atmospheric pressure in the space communicating with the air suction hole 209D. The controller determines whether or not the difference in atmospheric pressure (atmospheric pressure difference) acquired at different timings is equal to or greater than the threshold value. The acquisition of atmospheric pressure by the atmospheric pressure sensor 211C and the determination process of the controller are performed periodically.

When the non-combustion suction device 1 is sucked by the user, air is sucked from the air suction hole 209D toward the cartridge case 3, so that the atmospheric pressure in the atmosphere of the pressure sensor 211C decreases. Therefore, the controller determines that the non-combustion type suction device 1 has been sucked when the atmospheric pressure difference is equal to or more than the threshold value, and transfers the electric power of the battery cell 203 to the heater in the cartridge case 3 via the positive electrode terminal 211A and the negative electrode terminal 211B. Controls the output to. The heater heats the liquid and the atomized liquid is sucked by the user through the cigarette capsule.

[Effects obtained by the embodiment]
According to the above-described embodiment, the following effects can be obtained.
The battery pack operates when the barometric pressure sensor detects a pressure difference above the threshold, so even if a child with weak suction power mischiefs or accidentally sucks a non-combustion type suction device, the non-combustion type It is possible to prevent the aspirator from operating.
When a barometric pressure sensor is applied to a non-combustion suction device, it is necessary to provide an air suction hole in order to detect the barometric pressure difference. Moisture may enter the holding space such as a battery cell through the air suction hole. However, according to the configuration according to the embodiment, since the packing is interposed between the substrate holder and the outer peripheral portion of the second circuit board, it is possible to prevent moisture from entering the holding space such as a battery cell. can do. Further, since the airtightness of the atmosphere of the barometric pressure sensor can be ensured, the detection accuracy of the sensor can be improved.

Further, since the O-ring is also interposed in the space generated between the connecting member and the substrate holder, it is possible to prevent moisture from entering the holding space such as a battery cell through the space.
