Description

Technical Field

[0001] The utility model relates to the technical field of atomization, in particular to atomization equipment with controllable oil injection amount. Background Art

[0002] The existing atomizing device has an oil storage chamber formed inside, and then the atomizing component is installed in the oil storage chamber. The atomizing component can absorb the oil in the oil storage chamber. Then, a power supply component is provided to power the atomizing component, so that the atomizing component is heated, thereby converting the absorbed oil into aerosol. The aerosol flows out through the nozzle of the atomizing device for the user to inhale.

[0003] In order to meet the requirements of large puff count and compliance, more and more external oil bottle atomizer devices have appeared on the market. An oil supply bottle is hung on the main body of the device to supply oil to the oil storage chamber of the main body of the device. During transportation, the oil supply bottle and the main body of the device are packaged separately to meet compliance requirements. When in use, the oil supply bottle is unsealed and installed on the main body of the device to increase the amount of smoke oil in the entire atomizer device and achieve a large puff count. However, the existing atomizer device is in a state of continuous oil supply after installation due to the unreasonable installation design of the oil supply bottle and the oil storage chamber. It is easy for the oil storage chamber to overflow due to excessive oil, which can easily cause oil leakage in the atomizer device. Therefore, it is necessary to design an atomizer device with controllable oil injection to avoid oil leakage in the atomizer device. Utility Model Content

[0004] The main purpose of the utility model is to provide an atomizing device with controllable oil filling amount, aiming to solve the problem that the oil supply bottle of the existing atomizing device is in a state of continuous oil supply, which easily causes excessive oil in the oil storage chamber to overflow, thereby easily causing oil leakage in the atomizing device.

[0005] To achieve the above-mentioned purpose, the atomizing device with controllable oil injection amount proposed by the present invention comprises:

[0008] A power supply assembly is located on one side of the oil storage bin and the oil supply bottle, and the power supply assembly is detachably connected to the oil storage bin and / or the oil supply bottle;

[0009] a blocking member comprising a connecting portion, and a blocking portion and a limiting portion respectively connected to both ends of the connecting portion, wherein the blocking portion is located in the oil storage cavity, the limiting portion is located in the oil passage, and the diameter of the limiting portion is larger than the inner diameter of the through hole, and the connecting portion is movably disposed through the through hole;

[0010] An elastic member is located in the oil passage and is movably sleeved on the connecting portion. One end of the elastic member is fixedly connected or abutted with the limiting portion. The minimum elastic force of the elastic member is greater than the gravity of the blocking member, so that the elastic member does not deform due to the gravity of the blocking member. In a natural state, the other end of the elastic member abuts against the outer wall of the through hole, and the blocking portion blocks the oil inlet hole and the through hole. When the elastic member is compressed by external force, the elastic member is compressed between the limiting portion and the outer wall of the through hole, and the blocking portion is away from the oil inlet hole.

[0011] Optionally, the oil supply bottle is installed at the lower end of the oil storage tank, the oil supply cavity is located below the oil storage cavity, and the oil inlet hole and the through hole are opened on the bottom wall of the oil storage cavity.

[0012] Optionally, a limiting groove is formed on the wall of the oil storage cavity, the oil inlet hole and the through hole are opened at the bottom of the limiting groove, and the blocking portion of the blocking member is at least partially movably inserted into the limiting groove.

[0015] Optionally, the sealing portion includes an inserting portion and a covering portion, the inserting portion is adapted to be inserted into the limiting groove, and the covering portion protrudes radially along the inserting portion to form a sealing step between the covering portion and the inserting portion, and the step surface of the sealing step is in contact with the top surface of the limiting groove.

[0016] Optionally, there are multiple oil inlet holes, and the multiple oil inlet holes are arranged around the through hole.

[0017] Optionally, the oil storage tank includes a tank body and a first sealing assembly, one side of the tank body is open, the first sealing assembly is installed on the open side of the shell to enclose the tank body to form the oil storage cavity, and the first sealing assembly forms an oil inlet channel;

[0018] The oil supply bottle includes an oil bottle body and a second sealing assembly. One side of the oil bottle body is open.

[0020] Optionally, the blocking member is a stainless steel blocking member; and / or the elastic member is a stainless steel elastic member.

[0021] The technical solution of the present invention can be achieved by setting an elastic member of appropriate length so that the elastic member can limit the blocking member in a natural state, so that the blocking member can block the oil inlet. When oil supply is needed, the oil supply amount of the oil supply bottle to the oil storage tank is controlled by adjusting the angle of the atomizing device and controlling the number of times the atomizing device is swung. In this way, on the one hand, the oil supply bottle will not continuously supply oil to the oil storage chamber, thus preventing the oil supply bottle from being in a continuous oil supply state for a long time, thereby preventing excessive oil in the oil storage chamber from overflowing, and effectively preventing the atomizing device from leaking oil. On the other hand, the atomizing device can be controlled so that the oil in the oil storage chamber cannot flow into the oil supply bottle during normal use, ensuring that there is oil in the oil storage chamber and that the air pressure in the oil storage chamber is not affected, thereby ensuring the normal use of the atomizing device.

[0035] The following mainly describes the specific structure of the atomizing device with controllable oil injection amount.

[0036] Reference Figures 1 to 6 In an embodiment of the present invention, the atomizing device with controllable oil injection amount comprises:

[0037] The device body 100 has an oil storage tank 110, and the oil storage tank 110 is provided with an oil storage cavity 113, and the cavity wall of the oil storage cavity 113 is provided with an oil inlet hole 116 and a through hole 117;

[0038] The oil supply bottle 200 is detachably mounted on the oil storage bin 110. The oil supply bottle 200 is provided with an oil supply cavity 201. An oil passage 120 is formed between the oil supply bottle 200 and the oil storage bin 110. One end of the oil passage 120 is in communication with the oil supply cavity 201, and the other end is in communication with the oil inlet hole 116 and the through hole 117.

[0039] A power supply assembly 500 is located on one side of the oil storage bin 110 and the oil supply bottle 200, and the power supply assembly 500 is detachably connected to the oil storage bin 110 and / or the oil supply bottle 200;

[0040] The blocking member 300 includes a connecting portion 320, a blocking portion 310 and a limiting portion 330 respectively connected to both ends of the connecting portion 320. The blocking portion 310 is located in the oil storage cavity 113, and the limiting portion 330 is located in the oil passage 120. The diameter of the limiting portion 330 is larger than the inner diameter of the through hole 117. The connecting portion 320 is movably disposed in the through hole 117.

[0041] The elastic member 400 is located in the oil passage 120 and is movably mounted on the connecting portion 320. One end of the elastic member 400 is fixedly connected or abutted with the limiting portion 330. The minimum elastic force of the elastic member 400 is greater than the gravity of the blocking member 300, so that the elastic member 400 does not deform due to the gravity of the blocking member 300. When the elastic member 400 is in a natural state, the other end of the elastic member 400 abuts against the outer wall of the through hole 117, and the blocking portion 310 blocks the oil inlet hole 116 and the through hole 117; when the elastic member 400 is compressed by external force, the elastic member 400 is compressed between the limiting portion 330 and the outer wall of the through hole 117, and the blocking portion 300 is away from the oil inlet hole 116.

[0042] Specifically, in this embodiment, there are many ways to detachably install the oil supply bottle 200 and the oil storage bin 110, such as snap-on, plug-in, screw connection, etc., which are not specifically limited here. Before using the atomizing device, a sealing plug can be used to seal the oil storage bin 110 and the oil supply bottle 200 respectively to ensure the sealing of the device body 100 and the oil supply bottle 200. Then the oil supply bottle 200 and the device body 100 can be packaged separately to meet compliance requirements. When in use, remove the sealing plug and install the oil supply bottle 200 on the oil storage bin 110 so that the oil storage bin 110 is connected to the oil supply bottle 200 for use. The power supply assembly 500 is located on one side of the oil storage bin 110 and the oil supply bottle 200. For example, the oil storage bin 110 and the oil supply bottle 200 are arranged up and down, and the power supply assembly 500 is located on the left or right side of the oil storage bin 110 and the oil supply bottle 200, or the oil storage bin 110 and the oil supply bottle 200 are arranged left and right, and the power supply assembly 500 is located below the oil storage bin 110 and the oil supply bottle 200, so as to ensure that the power supply assembly 500 has a larger volume, increase the amount of power that the power supply assembly 500 can supply, and also make the structure of the atomization device regular. The power supply assembly 500 is detachably connected to the oil storage bin 110 and / or the oil supply bottle 200, and the method can be selected from magnetic attraction, snap-on connection, plug-in connection, etc., and no specific limitation is made here. As long as the power supply assembly 500 is detachable from the oil supply bottle 110 and the oil storage bin 200, it is convenient to replace one of them, thereby improving the flexibility of the atomization device.

[0043] The elastic member 400 can be set to an appropriate length so that the atomizing device is in a natural state (that is, the elastic member is in a naturally extended state when not subjected to external force) under normal use. One end of the elastic member 400 abuts or is connected to the limiting portion 330, and the other end abuts against the outer wall of the through hole 117. Since the elastic member 400 is sleeved on the connecting portion 320 of the blocking member 300, the spring has a limiting effect on the blocking member 300 at this time, and the blocking member 300 can be limited to a position where the blocking portion 310 can just block the oil inlet hole 116 and the through hole 117, so that the oil cannot pass through. That is, the oil in the oil supply bottle 200 cannot reach the oil storage chamber 113, and the oil in the oil storage chamber 113 will not flow into the oil supply bottle 200, nor will it affect the air pressure in the oil storage chamber 113, thereby ensuring the sealing of the oil storage chamber 113 and thus ensuring the use effect of the atomizing device. It is worth mentioning that the elastic member 400 in its natural state may also include a situation where both ends of the elastic member 400 are subjected to a slight extrusion force but do not undergo significant elastic deformation, thereby ensuring that the two ends of the elastic member 400 are respectively in contact with or connected to the limiting portion 330 and the outer wall of the through-hole 117. It can be explained that because the minimum elastic force of the elastic member 400 is greater than the weight of the blocking member 300, that is, the minimum external force required to cause the elastic member 400 to elastically deform is greater than the weight of the blocking member 300, even when the atomizing device is located below the blocking member 300, the elastic member 400 will not deform (including microscopically small deformation) due to the weight of the blocking member 300. Therefore, in the absence of external force, the elastic member 400 maintains its limiting effect on the blocking member 300, so that the blocking member 300 continues to block the oil inlet 116.

[0044] When the oil in the oil storage chamber 113 is less or used up, the angle of the atomizing device can be adjusted so that the oil supply tank is located below the oil storage tank 110, and then the atomizing device is swung hard to compress the elastic member 400. At this time, the blocking member 300 will move downward due to its own gravity or the gravity of the blocking member 300 plus the tension of the spring, thereby moving away from the oil inlet hole 116. At this time, the oil in the oil supply tank can enter the oil storage chamber 113 through the oil passage 120 and the oil inlet hole 116 due to its own gravity, thereby realizing oil supply. When the oil in the oil supply bottle 200 is used up, a new oil supply bottle 200 can be replaced. In order to increase the speed at which the oil enters the oil storage chamber 113, the number of oil inlet holes 116 can be multiple, and the multiple oil inlet holes 116 are arranged around the through hole 117.

[0045] The technical solution of the present invention can be achieved by setting an elastic member 400 of appropriate length so that the elastic member 400 can limit the blocking member 300 in its natural state, so that the blocking member 300 can block the oil inlet 116. When oil supply is needed, the oil supply amount of the oil supply bottle 200 to the oil storage tank 110 can be controlled by adjusting the angle of the atomizing device and controlling the number of times the atomizing device is swung. In this way, on the one hand, the oil supply bottle 200 will not continuously supply oil to the oil storage chamber 113, avoiding the oil supply bottle 200 being in a continuous oil supply state for a long time, thereby avoiding excessive oil in the oil storage chamber 113 and overflow, thereby effectively avoiding oil leakage in the atomizing device. On the other hand, the oil in the oil storage chamber 113 can be controlled to not flow into the oil supply bottle 200 during normal use of the atomizing device, ensuring that there is oil in the oil storage chamber 113 and that the air pressure in the oil storage chamber 113 is not affected, thereby ensuring normal use of the atomizing device.

[0046] In some embodiments, the oil supply bottle 200 is mounted at the lower end of the oil storage bin 110, the oil supply chamber 201 is located below the oil storage chamber 113, and the oil inlet hole 116 and the through hole 117 are formed on the bottom wall of the oil storage chamber 113. Thus, during normal use of the atomizer, the blocking member 300 is positioned above the oil inlet hole 116, and the blocking member 300 can be pressed against the outer wall of the oil inlet hole 116 by its own gravity, further enhancing the blocking effect of the blocking member 300.

[0047] In some embodiments, the wall of the oil storage cavity 113 forms a limiting groove 114, the oil inlet hole 116 and the through hole 117 are disposed at the bottom of the limiting groove 114, and the blocking portion 310 of the blocking member 300 is at least partially movably engaged with the limiting groove 114. The provision of the limiting groove 114 serves to limit the blocking member 300, preventing it from shifting or tilting, and further improving the blocking effect of the blocking member 300. To reduce or even eliminate the effect of the limiting groove 114 on the oil inlet, in some embodiments, the width of the limiting groove 114 gradually increases from the bottom of the limiting groove 114 toward the groove opening. That is, the limiting groove 114 is outward-expanding. When the blocking member 300 is away from the oil inlet 116, a larger gap is provided between the peripheral side of the blocking member 300 and the side groove wall of the limiting groove 114 for oil to pass through, thereby reducing or even avoiding the influence of the limiting groove 114 on the oil inlet.

[0048] In some embodiments, a sealing protrusion 115 is provided on the side wall of the limiting groove 114, and the sealing protrusion 115 is used to abut against the outer peripheral wall of the blocking portion 310. When the blocking portion 310 is inserted into the limiting groove 114 to block the oil inlet hole 116, the sealing protrusion 115 abuts against the outer peripheral wall of the blocking portion 310, further ensuring the sealing of the oil storage chamber 113, thereby ensuring the use effect of the atomization device.

[0049] In some embodiments, the sealing portion 310 includes an inserting portion and a covering portion. The inserting portion is adapted to be inserted into the limiting groove 114. The covering portion protrudes radially from the inserting portion to form a sealing step 311 between the covering portion and the inserting portion. The step surface of the sealing step 311 is in contact with the top surface of the limiting groove 114. Similarly, this arrangement can improve the sealing effect within the oil storage chamber 113, thereby improving the performance of the atomizing device.

[0050] Regarding the specific structures of the oil storage tank 110 and the oil supply bottle 200, in some embodiments, the oil storage tank 110 includes a tank body 111 and a first sealing assembly 112. The tank body 111 has an open side, and the first sealing assembly 112 is mounted on the open side of the housing to enclose the oil storage chamber 113 with the tank body 111. The first sealing assembly 112 forms an oil inlet passage. The oil supply bottle 200 includes an oil bottle body 210 and a second sealing assembly 220. The oil bottle body 210 has an open side, and the second sealing assembly 220 is mounted on the open side of the oil bottle body 210 to enclose the oil supply chamber 201 with the oil bottle body 210. The second sealing assembly 220 forms an oil supply passage. The second sealing assembly 220 is at least partially inserted into the oil inlet passage, and the oil supply passage and the oil inlet passage together form the oil passage 120. That is, the oil supply bottle 200 is installed in the oil storage tank 110 by plugging, which improves the convenience of disassembly.

[0051] Furthermore, a sealing ring 221 is provided on the outer wall of the second sealing assembly 220, and the sealing ring 221 abuts against the side wall of the oil inlet channel. The second sealing ring 221 acts as a seal to prevent oil from leaking between the outer wall of the second sealing assembly 220 and the inner wall of the oil inlet channel, thereby preventing oil leakage.

[0052] In some embodiments, the blocking member 300 is a stainless steel blocking member 300; and / or the elastic member 400 is a stainless steel elastic member 400. Stainless steel is high-quality, corrosion-resistant, and chemically stable, ensuring that the blocking member 300 and the elastic member 400 do not chemically react with the oil, thereby maintaining the taste of the oil after being converted into aerosol. It also increases the weight of the blocking member 300, making it less likely to shake, thereby improving the sealing effect of the blocking member 300.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
