Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an atomization component and atomizer. Background Technology

[0002] Existing atomizers typically consist of an oil cup and an atomizing component housed within the oil cup. An oil cavity is formed between the oil cup and the atomizing component. The atomizing component has an inlet port communicating with the oil cavity, and the structure of the inlet port limits the liquid delivery speed. The liquid delivery channel formed by the common inlet port is usually equal to the wall thickness of the atomizing component, and the channel is relatively short. The liquid delivery speed is determined by the cross-sectional size of the inlet port. During continuous atomization, if the inlet port is too small, the liquid delivery may be obstructed, causing the liquid delivery speed to lag behind the atomization speed. This can lead to problems such as dry burning and a burnt taste at the heating element, further affecting the user's vaping experience. Conversely, if the inlet port is too large, atomized liquid may leak into the atomizing channel, causing leakage. Utility Model Content

[0003] The main purpose of this invention is to propose an atomizing component and atomizer, which can, to some extent, solve the shortcomings of the oil guiding structure of the atomizer in the prior art.

[0006] The inner shell has an atomizing chamber inside. The inner shell is at least partially disposed in the receiving cavity. The outer wall of the inner shell and the inner wall of the outer shell are connected on the side near the liquid inlet end to form the top of the liquid storage cavity. The inner shell is provided with a liquid inlet communicating with the liquid storage cavity.

[0035] This application provides an atomizing component, see [link to relevant documentation] Figure 1-9 As shown, the atomizing component 10 has a liquid storage chamber 114 for storing the atomizing matrix and a heating element 13 for heating the atomizing matrix to generate aerosol.

[0036] Specifically, the atomizing component 10 includes an outer shell 11 and an inner shell 12, with a liquid storage chamber 114 for storing the atomizing matrix between the outer shell 11 and the inner shell 12.

[0037] The housing 11 has a cavity defined in the height direction. The housing 11 is provided with a liquid guiding channel 112 extending downward in the height direction. The liquid guiding channel 112 communicates the cavity with the outside, so as to replenish the atomizing matrix into the cavity through the liquid guiding channel 112. It is understood that the liquid guiding channel 112 has a vertical height, which allows the liquid atomizing matrix to pass through the liquid guiding channel 112 under its own weight.

[0038] Understandably, in the actual application of the atomizing component 10, due to its small structure and limited overall space, the cross-section of the liquid guiding channel 112 is small. During the liquid delivery process, the flow of liquid in the liquid guiding channel 112 is easily restricted by air bubbles.

[0039] In some embodiments, a plurality of liquid guiding channels 112 are uniformly provided on the outer casing 11. For example... Figure 3 or Figure 5As shown, the outer shell 11 has a generally flat top with four liquid guiding channels 112 evenly distributed on the top. Each liquid guiding channel 112 is recessed from the top to form a deep groove, and the bottom or side wall of the groove is provided with an outlet for liquid to communicate with the interior of the outer shell 11.

[0040] In some embodiments, the opening at the inlet end of the liquid guiding channel 112 is larger than the opening at the outlet end. When the atomizing matrix enters the liquid guiding channel 112, the pressure at the outlet end is lower than that at the inlet end due to the narrowing of the outlet 113. This increases the flow rate of the atomizing matrix at the outlet end and causes the bubbles to be compressed and deformed under the influence of the flow rate, allowing them to pass through the outlet end and preventing the liquid guiding channel 112 from being blocked.

[0041] Furthermore, since the opening at the liquid outlet is smaller than the opening at the liquid inlet, a vortex can be formed in the liquid guiding channel 112 when the atomizing matrix passes through the liquid guiding channel 112. The vortex can deform or break the bubbles, reducing the restriction of the bubbles on the liquid flow.

[0042] In some embodiments, the height of the outlet opening is less than or equal to the height of the storage chamber 114. For example... Figure 8 As shown, the opening at the liquid outlet is elongated and narrow, and its height is greater than or equal to half the height of the liquid storage chamber 114. When liquid enters the liquid storage chamber 114 through the opening at the liquid outlet, the liquid entering the liquid storage chamber 114 can contact the upper half of the space in the liquid storage chamber 114. In particular, in some embodiments, a liquid storage cotton 14 is provided inside the liquid storage chamber 114. As a porous medium, the liquid storage cotton 14 can quickly absorb the atomizing matrix through capillary action and guide the atomizing matrix to the atomization chamber 120.

[0043] Understandably, although the liquid storage cotton 14 can store and transport the atomized matrix, its pores are small and the liquid flow is slow. After the liquid storage cotton 14 is installed in the liquid storage cavity 114, there is at least one of the following gaps between the outer wall of the liquid storage cotton 14 and the inner wall of the liquid storage cavity 114: an upper gap 16, a side gap, and a lower gap 17.

[0044] The liquid storage cotton 14 includes an upper cotton body 142 and a lower cotton body 141. The upper cotton body 142 is shaped to fit the inner wall of the liquid storage cavity 114, and the lower cotton body 141 is in clearance fit with the liquid storage cavity 114. The gap between the lower cotton body 141 and the liquid storage cavity 114 is connected to the liquid guiding channel 112.

[0045] like Figure 6As shown, the upper gap 16 is the gap between the top surface of the liquid storage cotton 14 and the top of the liquid storage chamber 114. The upper gap 16 connects to the atomization chamber 120 to balance the liquid storage chamber 114 with the external air pressure and promote the flow of the atomization matrix. It can be understood that the distance of the upper gap 16 between the inner wall of the outer shell 11 and the outer wall of the inner shell 12 is between 0.5-3mm, and the gap is smaller than the width of the liquid storage chamber 114, so that the liquid surface can form a liquid seal near the upper gap 16 to prevent liquid from entering the upper gap 16 and affecting the balance between the liquid storage chamber 114 and the external atmosphere.

[0046] like Figure 7 As shown, the side gap is a longitudinal groove formed on the outer wall of the liquid storage cotton 14 or the inner wall of the liquid storage cavity 114, so as to guide the atomized matrix to flow quickly from one end of the groove to the other end, thereby accelerating the absorption efficiency of the liquid storage cotton 14.

[0047] The lower gap 17 is the gap between the bottom of the liquid storage cotton 14 and the bottom of the liquid storage chamber 114. The gap accelerates the flow of the atomizing matrix to prevent the heating element 13 from dry burning or producing burnt aerosol due to lack of atomizing matrix.

[0048] like Figure 8 As shown, a support portion 115 is provided at the upper part of the liquid storage chamber 114. The support portion 115 protrudes from the top of the liquid storage chamber 114 to form the aforementioned upper gap 16 between the liquid storage cotton 14 and the top of the liquid storage chamber 114. After the liquid storage cotton 14 absorbs the atomized matrix, the liquid storage cotton 14 can expand to the upper gap 16.

[0049] like Figure 9 As shown, the liquid storage cotton 14 is provided with an installation channel 140. The inner shell 12 passes through the installation channel 140 and is fixed to the outer shell 11. The liquid storage cotton 14 is wrapped around the outer wall of the inner shell 12 to prevent the atomized matrix from forming a surge that impacts the inner shell 12 and causes the atomized matrix to overflow.

[0050] In some embodiments, the inlet opening has a generally triangular cross-section. For example... Figures 3 to 5 As shown, the liquid guiding channel 112 is a deep groove that is recessed downward from the side of the outer shell 11 near the top. The groove has a triangular cross-section and an opening at the bottom of the groove for the atomized matrix to flow out.

[0051] like Figures 3 to 5 As shown, the bottom of the outer shell 11 is defined by an air inlet 110 and the top is defined by an air outlet 111. The air outlet 111 is connected to the atomizing chamber 120 of the atomizing component 10. External air enters the atomizing chamber 120 from the air inlet 110 and is discharged from the air outlet 111 as a mixed aerosol.

[0052] The inner shell 12 defines an atomizing chamber 120. The inner shell 12 is at least partially disposed within the receiving cavity. The outer wall of the inner shell 12 and the inner wall of the outer shell 11 are connected near the liquid inlet to form the top of a liquid storage chamber 114. The inner shell 12 has a liquid inlet communicating with the liquid storage chamber 114. See also... Figure 4 and Figure 9 As shown, the inner shell 12 is generally tubular. One end of the tube is inserted into the receiving cavity and connected to the outer shell 11 and communicates with the air outlet 111 of the outer shell 11. The other end of the tube passes through the bottom of the outer shell 11 and communicates with the air inlet 110 on the outer shell 11. The outer wall of the tube and the inner wall of the outer shell 11 define a liquid storage chamber 114 for storing the atomized matrix. The outer wall of the tube is provided with a liquid inlet hole 123 that communicates with the liquid storage chamber 114.

[0053] In some embodiments, the pipe body is further provided with an air passage 122 communicating with the liquid storage chamber 114. For example... Figure 8 As shown, the tube body is provided with multiple air passage holes 122. The air passage holes 122 are located in the area of ​​the tube body that is perpendicularly projected onto the upper gap 16. The diameter of the air passage holes 122 is approximately 0.5-1.5 mm.

[0054] In some embodiments, when the housing 11 is provided with multiple liquid guiding channels 112, the projection of the liquid inlet is located between the openings of two adjacent liquid outlets. This is to prevent the atomizing matrix from flowing into the atomizing chamber 120 too quickly. Further, as... Figure 8-9 As shown, the atomization chamber 120 is also provided with a liquid guiding cotton 15, which is fixed to the heating element 13 in the atomization chamber 120 and is used to guide the atomization matrix to be transported to the heating element 13.

[0055] The heating element 13 in existing atomizing components 10 can be linear, mesh-like, or ceramic. For example... Figure 8-9 As shown, in some embodiments, the heating element 13 is a mesh heating sheet, the liquid-absorbing surface of the heating element 13 is fixed on the liquid-guiding cotton 15, and the atomizing surface of the heating element 13 is exposed in the atomizing chamber 120 to heat the atomizing matrix absorbed by the liquid-absorbing surface to generate an aerosol.

[0056] Based on the atomizing component 10 described in the above embodiments, this application also provides an atomizer 1, such as... Figure 10-11 As shown, the atomizer 1 includes the atomizing component 10 described in any of the above embodiments.

[0057] In some embodiments, the atomizer 1 further includes an oil cup 100, which internally defines an oil cavity 101 for storing the atomizing matrix and supplies it to the reservoir cavity 114 of the atomizing assembly 10. For example... Figure 11 As shown, the flat portion of the outer casing 11 forms at least a part of the bottom of the oil cup 100. It is understood, of course, that the inlet opening of the liquid channel 112 is located at the bottom of the oil cavity 101.

[0058] The outer wall of the oil cup 100 can serve as the outer wall of the atomizer 1, meaning the mouthpiece 102 of the atomizer 1 can be constructed on the oil cup 100. For example... Figure 11 As shown, the oil cup 100 has a mouthpiece 102 on one side, and the air inlet of the atomizing component 10 is connected to the mouthpiece 102 inside the oil cup 100. An oil cavity 101 is formed between the inner wall of the oil cup 100 and the outer wall of the housing 11 of the atomizing component 10.
