Description

Technical Field

[0001] The present application relates to the technical field of atomization equipment, and in particular to an atomizer and an atomization device. Background Art

[0002] The atomizers of some atomizing devices have an atomizing chamber and a liquid storage container, both of which can store atomizing liquid. The atomizing liquid in the atomizing chamber is used to supply an atomizing core assembly in the atomizer so as to be heated by the atomizing core assembly to generate an aerosol, while the atomizing liquid in the liquid storage container can be transported to the atomizing chamber to replenish the atomizing liquid in the atomizing chamber.

[0003] Since most liquid storage containers rely on the liquid level difference to transport the atomized liquid to the atomizing chamber, there is a common problem of lack of control during the infusion process. If the infusion speed is too fast, the atomizing chamber may leak, and if the infusion speed is too slow, the liquid supply to the atomizing core assembly will not be timely, causing the atomizing core to dry burn or burn, which will affect the user experience. Summary of the invention

[0021] In one embodiment, the flow limiting structure also includes a partition portion for separating the infusion channel, the partition portion is arranged on a side of the flow limiting component close to the atomization chamber, and at least one liquid conducting hole is provided on the partition portion, and the liquid conducting hole is used to connect the atomization chamber and the infusion groove to limit the input speed of the atomized liquid.

[0022] In one embodiment, the partition portion has a supporting protrusion on a side close to the flow limiting member, and the supporting protrusion is used to position the flow limiting member so that a first gap for connecting the liquid guiding through hole and the infusion groove is formed between the flow limiting member and the partition portion;

[0029] According to the atomizer of the above embodiment, the liquid storage container is arranged on one side of the atomizing chamber in the atomizing main unit, and the two are connected through an infusion channel. When in use, the atomized liquid in the liquid storage container can be input into the atomizing chamber through the infusion channel. As the atomized liquid in the liquid storage container decreases, due to the provision of a limited flow structure, when the atomized liquid floods the infusion channel, the air can be restricted from entering the atomizing main unit from the atomizing chamber, so that the pressure in the liquid storage container gradually decreases, and the atomized liquid therein cannot continue to be output due to the pressure difference, which helps to reduce the risk of leakage caused by the continuous input of the atomized liquid into the atomizing chamber.

[0030] When it is necessary to add atomized liquid to the atomizing chamber, the gas regulating component is controlled to open the air guide channel to connect the inner cavity of the liquid storage container with the external atmosphere, and the pressure in the liquid storage container is supplemented, so that the atomized liquid in the liquid storage container can continue to be input into the atomizing chamber, and the input speed is limited by the flow limiting structure, and it is not easy to over-replenish and cause leakage. After the liquid replenishment is completed, the gas regulating component is controlled to close the air guide channel, so that the continuous output of the atomized liquid in the liquid storage container can be suppressed.

[0031] By utilizing the principle of pressure difference, timely controlling the opening and closing of the gas regulating component and setting a current limiting structure to limit the infusion speed during fluid replenishment, it helps to control the infusion process, reduce the risk of leakage caused by too fast or excessive infusion, or dry burning and sticking of the atomizer core component caused by too slow infusion, and help improve the user experience.

In addition, the structural design is simple, easy to produce and assemble, and helps to control production costs.

[0051] Embodiment of the atomizer in this application:

[0052] In one embodiment, please refer to Figures 1 to 10 The atomizer includes an atomizer host 100 and a liquid storage container 200.

[0053] In order to describe the atomizer host 100 and the atomizer in more detail, three mutually perpendicular directions are defined herein based on the structural structure of the atomizer host 100, namely: a first direction, a second direction and a third direction; illustratively, the first direction refers to Figure 1 The up and down directions of the atomizer host 100 shown in the figure, and the second direction refers to Figure 1 The left and right directions and the third direction of the atomizer host 100 shown in Figure 1 The front and rear directions of the atomizer host 100 are shown in FIG.

[0054] Please refer to Figure 1 and Figure 2 The atomizer host 100 can be understood as a collection of parts in the atomizer, such as the housing, the atomizer core assembly 130, etc., except for the liquid storage container 200. In one embodiment, the atomizer host 100 has a nozzle setting position 110 at one end along the first direction. The nozzle setting position 110 can be understood as a position for installing a nozzle, or a position where a nozzle is set, that is, the nozzle setting position 110 can be fixedly set with a nozzle, or can be used to assemble a nozzle.

[0055] Please refer to Figure 2 The atomizer main unit 100 is provided with an atomizer chamber 120 for storing atomized liquid. The atomizer main unit 100 includes an atomizer core assembly 130 disposed in the atomizer chamber 120. The atomizer core assembly 130 is used to heat the atomized liquid to generate an aerosol. The atomizer main unit 100 may also include a liquid storage member 140, which is disposed in the atomizer chamber 120 and is coated on the circumference of the atomizer core assembly 130 to supply the absorbed atomized liquid to the atomizer core assembly 130.

[0056] Exemplarily, the atomizer core assembly 130 includes an atomizer tube 131 and an atomizer core body 132, the atomizer tube 131 is installed in the atomizer chamber 120, and the atomizer tube 131 has an air inlet end connected to the outside of the atomizer, and an air outlet end connected to the suction nozzle arranged at the suction nozzle setting position 110. The atomizer core body 132 is arranged in the atomizer tube 131, and a liquid inlet hole is arranged on the atomizer tube 131 corresponding to the atomizer core body 132. The liquid storage member 140 is coated on the circumference of the atomizer tube 131 to absorb the atomized liquid entering the atomizer chamber 120, and the atomized liquid is supplied to the atomizer core body 132 through the liquid inlet hole, and the atomized liquid is heated by the atomizer core body 132 to generate an aerosol.

[0057] Please refer to Figure 3 The liquid storage container 200 is used to store the atomized liquid and supply the stored atomized liquid to the atomizing chamber 120. In one embodiment, the liquid storage container 200 is disposed on one side of the atomizing chamber 120 along the second direction, and an infusion channel 121 for connecting the liquid storage container 200 and the atomizing chamber 120 is disposed between the liquid storage container 200 and the atomizing chamber 120, and the infusion channel 121 is connected to a side of the liquid storage container 200 away from the nozzle setting position 110.

[0058] In one embodiment, please refer to Figure 2 and Figure 3The atomizing host 100 may have a mounting groove 150 on one side along the second direction, and the liquid storage container 200 is inserted into the mounting groove 150 along the second direction. The atomizing chamber 120 and the liquid storage container 200 are arranged side by side along the second direction. A container opening 210 is arranged on the container wall of the liquid storage container 200 facing the atomizing chamber 120, and the container opening 210 is located on the side of the liquid storage container 200 away from the nozzle setting position 110, that is, Figure 1 The bottom side of the liquid storage container 20 in the perspective shown. The atomizing chamber 120 has a first convex tube portion 122 and a second convex tube portion 123 on the cavity wall facing the liquid storage container 200. The second convex tube portion 123 is arranged around the first convex tube portion 122 at intervals. The inner cavity of the first convex tube portion 122 is connected to the atomizing chamber 120 to serve as an infusion channel 121.

[0059] Please refer to Figure 3 and Figure 4 When the liquid storage container 200 is installed in the installation groove 150, the container mouth 210 is inserted between the second convex tube part 123 and the first convex tube part 122, so that the liquid storage container 200 is connected to the atomizing chamber 120. A sealing sleeve 211 can be set on the container mouth 210, or a sealing ring can be set in the gap between the first convex tube part 122 and the second convex tube part 123. The sealing sleeve 211, the sealing ring and other sealing components are used to reduce the risk of leakage at the connection point between the liquid storage container 200 and the atomizing chamber 120.

[0060] In some embodiments, please refer to Figure 2 and Figure 5 In order to improve the fixing stability of the liquid storage container 200, an elastic clip 151 is provided on at least one of the groove wall of the installation groove 150 and the container wall of the liquid storage container 200, and a clamping groove 220 for the elastic clip 151 to be clamped is provided on the other, so that the liquid storage container 200 is clamped in the installation groove 150.

[0061] Exemplarily, elastic buckles 151 are provided on the groove walls on both sides of the mounting groove 150 along the first direction, and snap grooves 220 are provided on the container walls on both sides of the liquid storage container 200 along the first direction. After the liquid storage container 200 is inserted into the mounting groove 150, the elastic buckle 151 snaps into the corresponding snap groove 220, so that the liquid storage container 200 is fixed in the mounting groove 150. The liquid storage container 200 can also be provided with a guide surface corresponding to the elastic buckle 151, so that when the liquid storage container 200 is inserted into the mounting groove 150, the guide surface first contacts the elastic buckle 151 to guide the deformation of the elastic buckle 151, thereby reducing the difficulty of inserting the liquid storage container 200.

[0062] In some embodiments, please refer to Figure 2 and Figure 6Positioning protrusions 152 for positioning the liquid storage container 200 can be provided on both sides of the installation groove 150 along the third direction, and recessed areas 230 for the positioning protrusions 152 to be embedded in can be provided on the container walls of the liquid storage container 200 on both sides along the third direction, so as to improve the fixing accuracy and fixing stability of the liquid storage container 200 through the embedded cooperation of the positioning protrusions 152 and the recessed areas 230.

[0063] In other embodiments, the liquid storage container 200 may also be disposed on one side of the atomizing chamber 120 along the first direction or other directions, as long as the design and use requirements are met. The liquid storage container 200 may be connected to the atomizing host 100 in other detachable or non-detachable ways.

[0064] Since the liquid storage container 200 is connected to the atomizing chamber 120 through the liquid infusion channel 121, if the liquid infusion speed is not controlled, the atomized liquid in the liquid storage container 200 may continue to flow into the atomizing chamber 120, increasing the risk of leakage. However, if the liquid infusion speed is limited to a too low level, the atomizing core assembly 130 may dry burn or burn due to insufficient liquid supply, affecting the user experience.

[0065] In one embodiment, please refer to Figures 3 to 5 The infusion channel 121 has a flow limiting structure 300 for forming an infusion resistance to limit the infusion flow rate; an air guide channel 240 is provided at one end of the liquid storage container 200 close to the nozzle setting position 110, and the air guide channel 240 is used to connect the inner cavity of the liquid storage container 200 with the external atmosphere. The liquid storage container 200 also includes an air regulating component 400 for controlling the opening and closing of the air guide channel 240.

[0066] Among them, the pressure in the liquid storage container 200 includes the gravity P1 of the atomized liquid and the pressure P2 of the bubbles in the atomized liquid; the atomization chamber 120 is connected to the external atmosphere through the atomization tube 131, the pressure in the atomization chamber 120 is the atmospheric pressure P, and the flow limiting structure 300 provides a resistance P3 along the way for the atomized liquid transportation.

[0067] When the gas regulating component 400 closes the gas guide channel 240, the relationship between the pressures in the atomizing chamber 120 and the liquid storage container 200 is: P+P3≥P1+P2, so that the atomized liquid in the liquid storage container 200 will not continuously flow to the atomizing chamber 120, but gradually reach a balance, and is not prone to leakage due to excessive infusion.

[0068] When the gas regulating component 400 opens the gas guiding channel 240 so that the inner cavity of the liquid storage container 200 is connected to the external atmosphere, the pressure in the liquid storage container 200 also includes the atmospheric pressure P, and the relationship between the pressures in the atomizing chamber 120 and the liquid storage container 200 is: P+P3<P1+P2+P, and the atomized liquid in the liquid storage container 200 can be input into the atomizing chamber 120 under the action of the pressure difference to replenish the atomized liquid in the atomizing chamber 120. After the replenishment is completed, the gas regulating component 400 closes the gas guiding channel 240, and the pressures in the atomizing chamber 120 and the liquid storage container 200 gradually reach the above-mentioned "balanced" state again, limiting the continuous delivery of the atomized liquid to the atomizing chamber 120.

[0069] By arranging the flow limiting structure 300 and the gas regulating component 400 in coordination, the above-mentioned pressure difference principle can be utilized to control the infusion process, reduce the risk of leakage caused by too fast or excessive infusion into the atomization chamber 120, and improve the user experience.

[0070] Those skilled in the art will appreciate that the specific structure of the gas regulating component 400 is not limited, as long as it can control the opening and closing of the gas guide channel 240. For example, the gas regulating component 400 can be configured as a blockage, which can be set in the gas guide channel 240 to isolate the gas guide channel 240 from the outside atmosphere, and removing the blockage can allow the gas guide channel 240 to communicate with the outside atmosphere. The gas regulating component 400 can also be configured as a valve, and the communication between the gas guide channel 240 and the outside atmosphere can be controlled by adjusting the opening and closing of the valve.

[0071] In one embodiment, please refer to Figure 5 and Figure 6 The air regulating component 400 includes an air regulating member 410, which is movably arranged on the liquid storage container 200, and a connecting port 411 is provided on the air regulating member 410; the air regulating member 410 has a connecting position and a locking position, when the air regulating member 410 is in the connecting position, the connecting port 411 is opposite to the air guide channel 240, so that the air guide channel 240 is connected with the external atmosphere through the connecting port 411; when the air regulating member 410 is in the locking position, the connecting port 411 and the air guide channel 240 are staggered, and the air regulating member 410 isolates the air guide channel 240 from the external atmosphere; the air regulating member 410 includes an operating part 412 for controlling the activity of the air regulating member 410 to switch between the connecting position and the locking position, at least the operating part 412 is exposed to the outside of the atomizer.

[0072] When in use, the operating part 412 can be controlled from outside the atomizer to move the gas regulating member 410 to the connecting position or the locking position, so that the gas guide channel 240 is opened and closed as needed, and the liquid storage container 200 is controlled to infuse liquid into the atomizing chamber 120.

[0073] In one embodiment, please refer to Figure 3An air inlet hole 153 is provided on the groove wall at one end of the mounting groove 150 along the first direction. The air inlet hole 153 is arranged side by side with the suction nozzle setting position 110, and is used to connect the connecting port 411 with the external atmosphere when the air regulating component 410 is in the connecting position; the operating part 412 is exposed to the air inlet hole 153, so that the operating part 412 can be operated through the air inlet hole 153 to drive the air regulating component 410 to move.

[0074] The air regulating component 410 can be an air regulating turntable, which can be rotatably arranged on the container wall of the liquid storage container 200 opposite to the air inlet hole 153, and the operating part 412 is arranged toward the air inlet hole 153; the air regulating component 400 also includes a knob 420, one end of which is inserted into the air inlet hole 153, and is connected to the operating part 412 in a detachable manner such as plug-in connection and threaded connection, so as to drive the air regulating turntable to rotate by rotating the knob 420; an air intake gap 421 is formed between the hole wall of the air inlet hole 153 and the outer peripheral wall of the corresponding knob 420, and the air intake gap 421 is used to intake air into the connecting port 411.

[0075] When assembling the atomizer, the liquid storage container 200 is inserted into the mounting groove 150 along the second direction. After the liquid storage container 200 is installed in place, the operating part 412 is directly opposite to the air inlet hole 153, and the knob 420 is installed on the operating part 412 along the air inlet hole 153, so that the knob 420 can be used as a control switch of the operating part 412, and can also be used as an anti-detachment structure of the liquid storage container 200 to limit the liquid storage container 200 from detaching from the mounting groove 150. The gas regulating component 400 has a simple structural design, is easy to produce and assemble, and helps to control production costs.

[0076] When it is necessary to add atomizing liquid to the atomizing chamber 120, the knob 420 is rotated to drive the gas regulating dial to rotate to Figure 5 The connecting position shown allows the air outside the atomizer to enter the liquid storage container 200 through the air inlet gap 421, the connecting port 411 and the air guide channel 240 in sequence, changing the pressure relationship between the liquid storage container 200 and the atomizing chamber 120, forming a pressure difference, so that the atomized liquid in the liquid storage container 200 is transported to the atomizing chamber 120.

[0077] In one embodiment, please refer to Figure 5 and Figure 6 A receiving groove 250 may be provided on the container wall of the liquid storage container 200 opposite to the air inlet hole 153, and at least a portion of the gas regulating turntable is rotatably embedded in the receiving groove 250. A sealing member 251 is sandwiched between the gas regulating turntable and the bottom wall of the receiving groove 250, and a gas guide hole 2511 is provided on the sealing member 251 corresponding to the gas guide channel 240; an annular sealing ridge is provided on the side of the sealing member 251 close to the gas regulating turntable, and the annular sealing ridge includes at least one circle of first annular ridges 2512 arranged around the gas guide hole 2511, and at least one circle of second annular ridges 2513 arranged circumferentially around the sealing member 251.

[0078] The sealing member 251 is provided to improve the sealing effect of the gas regulating turntable on the gas guide channel 240, avoid damaging the pressure balance in the liquid storage container 200 and the atomizing chamber 120 due to air leakage, and reduce the risk of continuous delivery of the atomized liquid in the liquid storage container 200 to the atomizing chamber 120. Those skilled in the art can understand that the first annular convex ridge 2512 and the second annular convex ridge 2513 can also be provided as needed, as long as they can meet the sealing requirements.

[0079] In other embodiments, the air regulating member 410 may also be configured to open and close in a sliding, translational, or flipping manner, and any configuration that can meet the design and usage requirements is acceptable.

[0080] In one embodiment, please refer to Figure 4 and Figure 7 The flow limiting structure 300 includes a flow limiting member 310 inserted in the infusion channel 121, the flow limiting member 310 has an outer peripheral surface that fits with the channel wall of the infusion channel 121, and at least one infusion groove 311 is provided on the outer peripheral surface of the flow limiting member 310, so that the atomized liquid in the liquid storage container 200 flows into the atomization chamber 120 through the infusion groove 311, and the infusion groove 311 is used to form an infusion resistance to limit the input speed of the atomized liquid. Exemplarily, the flow limiting member 310 is roughly a cylindrical structure, and the outer diameter of the flow limiting member 310 is equal to or slightly larger than the inner diameter of the infusion channel 121, so that when the flow limiting member 310 is inserted in the infusion channel 121, at least part of the outer peripheral surface of the flow limiting member 310 fits with the channel wall of the infusion channel 121, and the infusion channel 121 is blocked, so that the atomized liquid can only flow through the infusion groove 311, thereby limiting the infusion speed of the atomized liquid. It also helps to limit the air from the atomizing chamber 120 passing through the liquid storage container 200, thereby reducing the risk of regulation failure of the air regulating component 400.

[0081] In one embodiment, a countersunk hole 312 is provided on the end surface of the flow limiting member 310 close to the liquid storage container 200, and the countersunk hole 312 is spaced apart from the infusion tank 311. For example, the countersunk hole 312 can be provided in the middle of the end surface of the flow limiting member 310. The provided countersunk hole 312 helps to collect particulate matter in the atomized liquid and reduce the risk of clogging of the infusion tank 311.

[0082] In one embodiment, please refer to Figure 4 and Figure 8 The flow limiting structure 300 further includes a partition part 320 for separating the infusion channel 121. The partition part 320 is disposed on a side of the flow limiting member 310 close to the atomizing chamber 120, and may be located at the end of the infusion channel 121 or in the infusion channel 121. The partition part 320 is provided with at least one liquid conducting through hole 321, and the liquid conducting through hole 321 is used to connect the atomizing chamber 120 and the infusion tank 311 to limit the input speed of the atomized liquid.

[0083] In order to prevent the flow-limiting member 310 from blocking the liquid-conducting through hole 321 and thus blocking the infusion channel 121, the flow-limiting member 310 should be spaced apart from the partition portion 320. In one embodiment, the partition portion 320 may have a support protrusion 322 on a side close to the flow-limiting member 310, and the support protrusion 322 is used to position the flow-limiting member 310, so that a first gap 3221 for connecting the liquid-conducting through hole 321 and the infusion groove 311 is formed between the flow-limiting member 310 and the partition portion 320.

[0084] In one embodiment, the flow limiting member 310 may have a reduced diameter section 313 on one side close to the partition portion 320 , and the outer peripheral surface of the reduced diameter section 313 is separated from the channel wall of the infusion channel 121 to form a second gap 3131 , and the infusion groove 311 is connected to the liquid guiding hole 321 through the second gap 3131 .

[0085] In one embodiment, please refer to Fig. 9 A liquid guide annular groove 124 is provided on the cavity wall of the atomizing cavity 120 on the side away from the nozzle setting position 110, and the liquid guide annular groove 124 is connected to the liquid storage component 140 and is communicated with at least one liquid guide through hole 321. The liquid guide annular groove 124 is used to transport the atomized liquid to the side of the atomizing cavity 120 away from the liquid storage container 200 along the second direction, so as to be partially absorbed by the liquid storage component 140 away from the liquid storage container 200, so that the liquid storage component 140 can supply the atomized liquid to the side of the atomizing core 132 away from the liquid storage container 200, which helps to reduce the risk of local dry burning of the atomizing core 132.
