Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to a method for selecting a sealing rod. Background Technology

[0002] Electronic atomizing devices primarily store liquids through an atomizer and, during use, convert the stored liquid into an aerosol for the user to inhale. To prevent the stored liquid from contacting air, which could lead to evaporation, oxidation, or off-flavors, electronic atomizers typically feature a sealing rod. This sealing rod extends into the atomizer's airflow channel and engages with two annular elastic elements within the atomizer to form a sealed atomization chamber, preventing liquid from leaking out of the storage tank. Therefore, selecting a sealing rod with an appropriate outer diameter is crucial to ensuring the sealing performance of the atomization chamber and to improve the ease of inserting and removing the sealing rod. Summary of the Invention

[0003] This application provides a method for selecting a sealing rod, which aims to better select a sealing rod with a suitable outer diameter to ensure the sealing performance of the atomizing sealing cavity and improve the convenience of inserting and removing the sealing rod.

[0004] Therefore, this application provides a method for selecting a sealing rod, which is used in an electronic atomizer and can extend from the shell of the electronic atomizer into the airflow channel of the electronic atomizer to interlock with an annular elastomer in the airflow channel to form an atomization sealing cavity; the selection method includes the following steps:

[0005] The initial outer diameter of the sealing rod is set according to the inner diameter of the annular elastomer, and the sealing rod having the initial outer diameter is formed by injection molding of silicone material;

[0006] The sealing rod is subjected to a maximum friction force test, and the maximum outer diameter of the sealing rod is obtained based on the test results of the maximum friction force test.

[0007] The sealing rod is subjected to a minimum friction force test, and the minimum outer diameter of the sealing rod is obtained based on the test results.

[0008] The outer diameter parameters of the sealing rod are set according to the maximum outer diameter value and the minimum outer diameter value.

[0009] Optionally, in some embodiments of this application, the sealing rod includes a first rod body and a second rod body connected to each other, and the annular elastomer includes a first annular elastic portion and a second annular elastic portion spaced apart in the airflow channel along the length direction of the airflow channel;

[0010] When the sealing rod extends from the housing of the electronic atomizer into the airflow channel of the electronic atomizer, the first rod body is inserted into the first annular elastic part, and the second rod body is inserted into the second annular elastic part, so as to form the atomization sealing cavity between the first annular elastic part and the second annular elastic part.

[0011] Optionally, in some embodiments of this application, the step of setting the initial outer diameter of the sealing rod according to the inner diameter of the annular elastomer includes:

[0012] The first initial outer diameter of the first rod is set according to the inner diameter of the first annular elastic part.

[0013] The second initial outer diameter of the second rod is set according to the inner diameter of the second annular elastic part.

[0014] Optionally, in some embodiments of this application, the step of injection molding the sealing rod having the initial outer diameter using silicone material includes:

[0015] After setting the injection mold according to the initial outer diameter, the pre-made silicone material is filled into the injection mold;

[0016] The injection mold filled with the pre-made silicone material is subjected to pressure holding, cooling, mold opening, and demolding processes in sequence to obtain the sealing rod with the initial outer diameter.

[0017] Optionally, in some embodiments of this application, the step of performing a maximum friction test on the sealing rod to obtain the maximum outer diameter value of the sealing rod based on the test result of the maximum friction test includes:

[0018] The sealing rod is initially assembled into the airflow channel using a preset method to detect the magnitude of the actual frictional force experienced when the sealing rod is pulled out.

[0019] Based on the relationship between the actual friction force and the preset maximum friction force threshold, the outer diameter of the sealing rod is adjusted until the actual friction force equals the preset maximum friction force threshold. Then, the current outer diameter of the sealing rod is taken as the maximum outer diameter value of the sealing rod.

[0020] Optionally, in some embodiments of this application, the step of adjusting the outer diameter of the sealing rod based on the relationship between the actual frictional force and a preset maximum frictional force threshold includes:

[0021] If the actual friction force is less than the preset maximum friction force threshold, then the outer diameter of the sealing rod is increased uniformly.

[0022] If the actual friction force is greater than the preset maximum friction force threshold, then the outer diameter of the sealing rod is reduced uniformly.

[0023] Optionally, in some embodiments of this application, the step of performing a minimum friction test on the sealing rod to obtain the minimum outer diameter value of the sealing rod based on the test result of the minimum friction test includes:

[0024] After the sealing rod is initially assembled into the airflow channel in a preset manner, the sealing rod assembled into the airflow channel is subjected to an inverted test.

[0025] Based on the test results of the inversion test, adjust the outer diameter of the sealing rod until the sealing rod just does not fall off, and take the current outer diameter of the sealing rod as the minimum outer diameter value of the sealing rod.

[0026] Optionally, in some embodiments of this application, the step of adjusting the outer diameter of the sealing rod based on the test results of the inversion test includes:

[0027] If the sealing rod falls off during the inversion test, the outer diameter of the sealing rod shall be increased uniformly.

[0028] If the sealing rod does not fall off during the inversion test, the outer diameter of the sealing rod is reduced uniformly.

[0029] Optionally, in some embodiments of this application, the method for determining whether the sealing rod will fall off includes:

[0030] If the sealing rod falls off during the current inversion test, but does not fall off during the subsequent inversion test, then it is determined that the sealing rod just happens not to fall off during the subsequent inversion test; or...

[0031] If the sealing rod does not fall off during the current inversion test, but falls off during the next inversion test, then it is determined that the sealing rod just did not fall off during the current inversion test.

[0032] Optionally, in some embodiments of this application, the step of setting the outer diameter parameter of the sealing rod based on the maximum outer diameter value and the minimum outer diameter value includes:

[0033] The average value of the maximum outer diameter and the minimum outer diameter is calculated, and the calculated average value is used as the outer diameter parameter of the sealing rod.

[0034] In this application's technical solution, when selecting a sealing rod with a suitable outer diameter for use in an electronic atomizer, allowing the sealing rod to extend from the atomizer's housing into the atomizer's airflow channel to interlock with a ring-shaped elastomer in the airflow channel to form an atomization sealing cavity, the initial outer diameter of the sealing rod is first set based on the inner diameter of the ring-shaped elastomer. After forming the sealing rod with the initial outer diameter through silicone injection molding, a maximum friction test is performed on the sealing rod to determine its maximum outer diameter. Simultaneously, a minimum friction test is performed on the sealing rod to determine its minimum outer diameter. Finally, the outer diameter parameter of the sealing rod is set based on both the maximum and minimum outer diameter values. Thus, through the above-described steps, since the outer diameter of the sealing rod has undergone maximum and minimum friction tests before selection, the sealing rod, when assembled into the corresponding airflow channel, can achieve the most suitable frictional force with the annular elastomer. This ensures the sealing performance of the atomizing sealing cavity while significantly improving the ease of inserting and removing the sealing rod. This technical solution allows for better selection of a sealing rod with a suitable outer diameter to ensure the sealing performance of the atomizing sealing cavity and improve the ease of inserting and removing the sealing rod.

[0049] In one embodiment, such as Figure 1 As shown in the figure, this application embodiment provides a method for selecting a sealing rod, which specifically includes the following steps:

[0050] Step S110: Set the initial outer diameter of the sealing rod according to the inner diameter of the annular elastomer, and form a sealing rod with the initial outer diameter by injection molding of silicone material.

[0051] It is understandable that, such as Figure 2 and Figure 3 As shown, the sealing rod 120 in this embodiment is mainly used in the electronic atomizer 1, and can extend from the housing 110 of the electronic atomizer 1 into the airflow channel 111 of the electronic atomizer 1 to interlock with the annular elastic body 130 in the airflow channel 111 to form an atomization sealing cavity 112. The electronic atomizer 1 here is mainly used in electronic atomization devices. In addition to the electronic atomizer 1, the electronic atomization device generally includes a power supply unit that supplies power to the electronic atomizer 1, so that the electronic atomization device can store liquid through the electronic atomizer 1, and under the power supply of the power supply unit, convert the stored liquid (specifically, it can be an atomizing liquid such as e-liquid) into an aerosol and spray it out for the user to inhale. Therefore, when the electronic atomizer 1 is in use, its sealing rod 120 should be pulled out from the airflow channel 111, so that both ends of the atomizing sealing chamber 112 are no longer sealed. This allows the atomizing sealing chamber 112 to connect with the air inlet of the housing 110 to introduce fresh gas, and to connect with the air outlet of the housing 110 to discharge the aerosol formed in the atomizing sealing chamber 112 for the user to inhale.

[0052] As described above, the sealing rod 120 mainly forms the atomizing sealing cavity 112 by interlocking with the annular elastomer 130 in the airflow channel 111. Therefore, the outer diameter of the sealing rod 120 should be compatible with the inner diameter of the annular elastomer 130. To select a suitable outer diameter for the sealing rod 120, the initial outer diameter of the sealing rod 120 must first be set according to the inner diameter of the annular elastomer 130. Since the outer diameter of the sealing rod 120 needs to be slightly larger than the inner diameter of the annular elastomer 130 to ensure sealing performance, a preset value can be added to the inner diameter of the annular elastomer 130 as the initial outer diameter of the sealing rod 120. This preset value can be 1mm to 3mm. After setting the initial outer diameter of the sealing rod 120, it can be injection molded with silicone material to form the sealing rod 120 with the initial outer diameter.

[0053] Step S120: Perform a maximum friction test on the sealing rod to obtain the maximum outer diameter value of the sealing rod based on the test results.

[0054] It is understandable that, such as Figure 2 and Figure 3As shown, based on the assembly relationship between the sealing rod 120 and the annular elastomer 130, it can be seen that, given the inner diameter and other parameters of the annular elastomer 130, the frictional force required to pull out the sealing rod 120 will increase as the outer diameter of the selected sealing rod 120 increases. To ensure the sealing performance of the atomizing sealing cavity 112 while facilitating the insertion and removal of the sealing rod 120, the maximum frictional force should not exceed the maximum frictional force threshold. That is, the outer diameter of the selected sealing rod 120 should not exceed its maximum outer diameter value. Thus, the maximum frictional force is set according to the maximum outer diameter value of the sealing rod 120. Therefore, after obtaining the sealing rod 120 with an initial outer diameter through the above method steps, the maximum frictional force test can be further performed on the sealing rod 120 to obtain the maximum outer diameter value of the sealing rod 120 based on the test results of the maximum frictional force test.

[0055] Step S130: Perform a minimum friction test on the sealing rod to obtain the minimum outer diameter value of the sealing rod based on the test results.

[0056] It is understandable that, such as Figure 2 and Figure 3 As shown, based on the assembly relationship between the sealing rod 120 and the annular elastomer 130, it can be seen that, given the inner diameter and other parameters of the annular elastomer 130, the frictional force required to pull out the sealing rod 120 will increase as the outer diameter of the selected sealing rod 120 increases. In order to ensure the sealing performance of the atomizing sealing cavity 112 while facilitating the insertion and removal of the sealing rod 120, the minimum frictional force should not be less than the minimum frictional force threshold, that is, the outer diameter of the selected sealing rod 120 should not be less than its minimum outer diameter value. Thus, the minimum frictional force is set according to the minimum outer diameter value of the sealing rod 120. Therefore, after obtaining the sealing rod 120 with an initial outer diameter through the above method steps, the minimum frictional force test can be further performed on the sealing rod 120 to obtain the minimum outer diameter value of the sealing rod 120 based on the test results of the minimum frictional force test.

[0057] Step S140: Set the outer diameter parameters of the sealing rod according to the maximum and minimum outer diameter values.

[0058] It is understandable that, such as Figure 2 and Figure 3As shown, when the maximum outer diameter and minimum outer diameter of the sealing rod 120 are obtained through the above methods, the outer diameter parameter of the sealing rod 120 can be reasonably set based on these values. A suitable value can be selected within the range between the maximum and minimum outer diameter values ​​as the outer diameter parameter of the sealing rod 120. Since this value is both greater than the minimum and less than the maximum outer diameter, when the sealing rod 120 with this outer diameter is assembled in the electronic atomizer 1, it will not slip out due to insufficient friction, affecting the sealing performance of the atomization sealing cavity 112, nor will it be difficult to pull out due to excessive friction, or even breakage. This significantly improves the ease of inserting and removing the sealing rod 120.

[0059] In this way, through the method steps provided in the embodiments of this application, since the outer diameter of the sealing rod 120 has undergone maximum friction force test and minimum friction force test respectively, the sealing rod 120 can have the most suitable friction force with the annular elastic body 130 after being assembled into the corresponding airflow channel 111. This ensures the sealing performance of the atomizing sealing cavity 112 while greatly improving the convenience of inserting and removing the sealing rod 120.

[0060] In some examples, such as Figure 2 and Figure 3 As shown, the sealing rod 120 specifically includes a first rod body 121 and a second rod body 122 connected to each other. The annular elastic body 130 includes a first annular elastic portion 131 and a second annular elastic portion 132 spaced apart along the length direction of the airflow channel 111. When the sealing rod 120 extends from the housing 110 of the electronic atomizer 1 into the airflow channel 111 of the electronic atomizer 1, the first rod body 121 engages with the first annular elastic portion 131, and the second rod body 122 engages with the second annular elastic portion 132, thereby forming an atomization sealing cavity 112 between the first annular elastic portion 131 and the second annular elastic portion 132. Thus, this structure ensures that both ends of the atomization sealing cavity 112 are well sealed and protected. Based on this, as... Figure 4 As shown, the specific process of performing the above method step "setting the initial outer diameter of the sealing rod 120 according to the inner diameter of the annular elastomer 130" is as follows:

[0061] Step S111: Set the first initial outer diameter of the first rod body according to the inner diameter of the first annular elastic part.

[0062] Step S112: Set the second initial outer diameter of the second rod body according to the inner diameter of the second annular elastic part.

[0063] It is understandable that, such as Figure 2 and Figure 3 As shown, the inner diameter of the first annular elastic portion 131 mentioned above can determine the first initial outer diameter of the first rod 121. Specifically, it can be obtained by increasing the inner diameter of the first annular elastic portion 131 by a preset value, which can be 1mm to 3mm. Similarly, the inner diameter of the second annular elastic portion 132 mentioned above can determine the second initial outer diameter of the second rod 122. Specifically, it can be obtained by increasing the inner diameter of the second annular elastic portion 132 by a preset value, which can be 1mm to 3mm. To facilitate the friction force test in subsequent steps, the difference between the first initial outer diameter and the inner diameter of the first annular elastic portion 131 should be equal to the difference between the second initial outer diameter and the inner diameter of the second annular elastic portion 132.

[0064] Thus, by using the above method steps, the first initial outer diameter of the first rod body 121 and the second initial outer diameter of the second rod body 122 that make up the sealing rod 120 can be set respectively, that is, all the initial outer diameter parameters of the sealing rod 120 can be set so that the sealing rod 120 with the corresponding parameters can be manufactured in subsequent method steps.

[0065] In some examples, such as Figure 5 As shown, the specific process of performing the above method step "forming a sealing rod with an initial outer diameter by injection molding of silicone material" is as follows:

[0066] Step S113: After setting the injection mold according to the initial outer diameter, fill the injection mold with pre-made silicone material.

[0067] Step S114: The injection mold filled with pre-made silicone material is subjected to pressure holding, cooling, mold opening and demolding processes in sequence to obtain a sealing rod with an initial outer diameter.

[0068] It is understood that the aforementioned injection mold should consist of two parts: one for filling with silicone and the other for forming the shape of the sealing rod 120. The pre-formed silicone material specifically refers to the silicone material prepared by mixing it uniformly according to a specified ratio, and adding auxiliary materials such as silicone adhesives or pigments when necessary, to meet the performance requirements of the sealing rod 120. When filling the injection mold with the pre-formed silicone material, it is necessary to ensure that the injection mold is completely filled and to avoid the formation of voids and air bubbles. This can usually be achieved by using pressure or vibration to ensure that the pre-formed silicone material is completely filled to every corner of the injection mold. The aforementioned pressure holding process specifically refers to applying a certain pressure to the injection mold after the filling is completed to ensure that the pre-formed silicone material is densely filled within the injection mold and maintains the required shape and size. The aforementioned cooling process specifically refers to allowing the pre-formed silicone material to gradually cool and solidify within the injection mold. This can usually be achieved through natural cooling or by using a cooling system to accelerate the cooling process. The aforementioned mold opening process specifically refers to opening the injection mold and removing the sealing rod 120 made from the pre-formed silicone material after the pre-formed silicone material has completely solidified. This process requires care to avoid damaging the injection mold or the sealing rod 120. The aforementioned demolding process specifically refers to removing the removed sealing rod 120 from the injection mold and performing necessary post-processing, such as trimming the edges and cleaning the surface, to make it meet the design requirements.

[0069] In this way, the sealing rod 120 with an initial outer diameter can be better formed by injection molding of silicone material through the above method steps.

[0070] In some examples, such as Figure 6 As shown, the specific process of performing the above method step "to perform a maximum friction test on the sealing rod, and to obtain the maximum outer diameter value of the sealing rod based on the test results" is as follows:

[0071] Step S121: Initially assemble the sealing rod into the airflow channel using a preset method to detect the magnitude of the actual frictional force experienced when the sealing rod is pulled out.

[0072] It is understandable that, such as Figure 2 and Figure 3As shown, the step of "preliminarily assembling the sealing rod into the airflow channel by a preset method" in this method can specifically be as follows: after aligning the sealing rod 120 with the air outlet of the airflow channel 111 of the electronic atomizer 1, press the sealing rod 120 into the airflow channel 111. When it cannot be pressed down, it indicates that the sealing rod 120 is properly assembled in the airflow channel 111. At this time, the insertion and removal test of the sealing rod 120 can be performed to detect the magnitude of the actual frictional force when the sealing rod 120 is pulled out. Specifically, a spring balance can be used to pull the sealing rod 120, and the frictional force can be determined by measuring the required pulling force. That is, the pulling force measured by the spring balance is taken as the magnitude of the actual frictional force when the sealing rod 120 is pulled out.

[0073] Step S122: Based on the relationship between the actual friction force and the preset maximum friction force threshold, adjust the outer diameter of the sealing rod until the actual friction force is equal to the preset maximum friction force threshold. Then, take the current outer diameter of the sealing rod as the maximum outer diameter value of the sealing rod.

[0074] It is understandable that, such as Figure 2 and Figure 3 As shown, after detecting the actual frictional force experienced by the sealing rod 120 when it is pulled out using the above method steps, the outer diameter of the sealing rod 120 can be further adjusted according to the relationship between the actual frictional force and the preset maximum frictional force threshold. This adjustment continues until the actual frictional force equals the preset maximum frictional force threshold. The current outer diameter of the sealing rod 120 is then taken as its maximum outer diameter. The specific process for adjusting the outer diameter of the sealing rod 120 according to the relationship between the actual frictional force and the preset maximum frictional force threshold is as follows: If the actual frictional force is less than the preset maximum frictional force threshold, the outer diameter of the sealing rod 120 is increased uniformly. If the actual frictional force is greater than the preset maximum frictional force threshold, the outer diameter of the sealing rod 120 is decreased uniformly. The adjustment of the outer diameter of the sealing rod 120 mentioned here and below specifically refers to re-injecting silicone material to form a sealing rod 120 with a new outer diameter. As mentioned earlier, the larger the outer diameter of the sealing rod 120, the greater the measured actual frictional force. Therefore, through the above adjustments, the actual frictional force can be adjusted to a level consistent with the preset maximum frictional force threshold more quickly. The preset maximum friction threshold mentioned here is set based on the weight range of the sealing rod 120. This ensures that the maximum force required to pull out the sealing rod 120 should be controlled within the weight range of the object, so that the user does not need to use excessive force when inserting or removing the sealing rod 120, making it easier for the user to insert or remove the sealing rod 120. When the actual friction force is adjusted to a level consistent with the preset maximum friction threshold, the current outer diameter of the sealing rod 120 can be used as the maximum outer diameter value of the sealing rod 120.

[0075] In this way, the maximum friction force test of the sealing rod 120 can be better performed through the above methods and steps, so as to obtain the maximum outer diameter value of the sealing rod 120 based on the test results of the maximum friction force test.

[0076] In some examples, such as Figure 6 As shown, the specific process of performing the above method step "to perform a minimum friction test on the sealing rod, and to obtain the minimum outer diameter value of the sealing rod based on the test results" is as follows:

[0077] Step S131: After initially assembling the sealing rod into the airflow channel using a preset method, perform an inverted test on the sealing rod assembled into the airflow channel.

[0078] It is understandable that, such as Figure 2 and Figure 3 As shown, the step of "preliminarily assembling the sealing rod 120 into the airflow channel 111 using a preset method" can specifically involve aligning the sealing rod 120 with the air outlet of the airflow channel 111 of the electronic atomizer 1, and then pressing the sealing rod 120 into the airflow channel 111. When it cannot be pressed down, it indicates that the sealing rod 120 is properly assembled in the airflow channel 111. At this point, a minimum friction test can be performed on the sealing rod 120 by performing an inversion test. That is, by inverting the sealing rod 120 assembled in the airflow channel 111 so that the air outlet of the airflow channel 111 faces downwards, observe whether the sealing rod 120 falls off.

[0079] Step S132: Based on the test results of the inversion test, adjust the outer diameter of the sealing rod until the sealing rod just does not fall off. Then, take the current outer diameter of the sealing rod as the minimum outer diameter value of the sealing rod.

[0080] It is understandable that, such as Figure 2 and Figure 3As shown, after performing the inversion test using the above methods and steps, the outer diameter of the sealing rod 120 can be further adjusted based on the test results until the sealing rod 120 just avoids falling off. The current outer diameter of the sealing rod 120 is then taken as its minimum outer diameter value. Specifically, the process of adjusting the outer diameter of the sealing rod 120 based on the inversion test results is as follows: If the sealing rod 120 falls off during the inversion test, its outer diameter is increased uniformly. If the sealing rod 120 does not fall off during the inversion test, its outer diameter is decreased uniformly. As mentioned above, the larger the outer diameter of the sealing rod 120, the greater the measured actual friction force, and the less likely the sealing rod 120 will fall off when inverted. Conversely, the smaller the outer diameter of the sealing rod 120, the smaller the measured actual friction force, and the more likely the sealing rod 120 will fall off when inverted. Therefore, through the above adjustments, the actual friction force can be adjusted more quickly to a level that prevents the sealing rod 120 from falling off. That is, the minimum value of the actual friction force should ensure that the sealing rod 120 just does not fall off. To better determine whether the sealing rod 120 just does not fall off, it can be judged in the following two ways: 1. If the sealing rod 120 falls off during the current inversion test, but does not fall off during the next inversion test, then it is determined that the sealing rod 120 just does not fall off during the next inversion test. Second, if the sealing rod 120 does not fall off during the current inversion test, but falls off during the next inversion test, then it is determined that the sealing rod 120 just did not fall off during the current inversion test.

[0081] In this way, the minimum friction force test of the sealing rod 120 can be better performed through the above method and steps, so as to obtain the minimum outer diameter value of the sealing rod 120 based on the test results of the minimum friction force test.

[0082] In some examples, the specific process of performing the above method step "setting the outer diameter parameter of the sealing rod based on the maximum and minimum outer diameter values" is as follows: The average value of the maximum and minimum outer diameter values ​​is calculated, and the calculated average value is used as the outer diameter parameter of the sealing rod 120. Thus, through the calculation of the average value in this method step, a more reasonable value can be obtained as the outer diameter parameter of the sealing rod 120. Since this value is both greater than the minimum outer diameter value and less than the maximum outer diameter value, when the sealing rod 120 with this outer diameter value is assembled in the electronic atomizer 1, it will not cause the sealing rod 120 to slip out and affect the sealing performance of the atomization sealing cavity 112 due to insufficient friction, nor will it cause the sealing rod 120 to be difficult to pull out or even break due to excessive friction. Therefore, the ease of inserting and removing the sealing rod 120 is greatly improved. Furthermore, based on this value, a range can be set where the minimum value of the range is greater than the minimum outer diameter value, and the maximum value of the range is less than the maximum outer diameter value. In this way, the setting of the range orientation can be used as a criterion for judging whether the sealing rod 120 is qualified, so as to better ensure that each sealing rod 120 produced will not slip out and affect the sealing performance of the atomizing sealing cavity 112 due to insufficient friction, and will not be difficult to pull out or even break due to excessive friction.
