[0006] In one embodiment, the spray head assembly has the first fastener, and the liquid storage assembly has the third fastener, wherein the first fastener rotates along the circumferential direction of the spray head assembly to a position where the third fastener is located and engages with the third fastener.

[0007] In one embodiment, the first fastener has opposing first and second ends along its extending direction, the third fastener has opposing third and fourth ends along its extending direction, the first end rotates toward the third fastener along the circumferential direction of the spray head assembly into the third fastener, and engages with the third fastener along the axial direction of the body, Here, one of the second end and the fourth end has a position limiting block, which is located in the rotation path of the first fastener and is used to prevent the first fastener from continuing to rotate in the current direction of rotation.

[0008] In one embodiment, the position limiting block is formed on the second end of the first fastener and is used to abut against the third end of the third fastener.

[0009] In one embodiment, one of the sides of the first fastener facing the third fastener and the side of the third fastener facing the first fastener has a bump, and the other side has a groove, the bump being fitted into the groove to fix the relative positions of the first and second fasteners along the circumferential direction of the liquid storage assembly.

[0010] In one embodiment, the groove is formed near the first end of the first fastener, and the bump is formed near the fourth end of the third fastener.

[0011] In one embodiment, the spray head assembly further includes a base body, and the first fastener includes a spray head connector and a flange, the spray head connector being connected to the base body, and the flange being connected to the side of the spray head connector and spaced apart from the base body. The liquid storage assembly includes a liquid storage case, and the third fastener includes a liquid storage connector and an engaging portion, the liquid storage connector being connected to the liquid storage case, the engaging portion being connected to one end of the liquid storage connector away from the liquid storage case, extending in a direction perpendicular to the axial direction of the liquid storage case, and defining a U-shaped groove together with the engaging portion and the liquid storage case, the flange portion rotating into the U-shaped groove and engaging with the liquid storage assembly.

[0012] In one embodiment, the position limiting block and the groove are each formed on the side surface of the flange portion facing the base body.

[0013] In one embodiment, the liquid storage assembly further has a liquid outlet, and the spray head assembly further has a liquid inlet, and both the first fastener and the third fastener are arc-shaped, with the first fastener positioned around the liquid inlet and the third fastener positioned around the liquid outlet.

[0014] In one embodiment, the spray head assembly further comprises the second fastener, the body comprises the fourth fastener, the second fastener rotates along the circumferential direction of the spray head assembly to a position where the fourth fastener is located, and engages with the fourth fastener.

[0015] In one embodiment, one of the body and the spray head assembly has an engaging ball, and the other has an engaging ball groove, the engaging ball rotates along the circumferential direction of the spray head assembly to a position where the engaging ball groove is located, and is fitted into the engaging ball groove to fix the relative position of the body and the spray head assembly.

Simultaneously, the rotary mechanism allows the first fastener to be aligned with the corresponding position on the liquid storage assembly to achieve engagement, and the second fastener to be aligned with the corresponding position on the main body to achieve engagement. This allows the first fastener to be smoothly moved to the engagement position corresponding to the liquid storage assembly, and the second fastener to be smoothly moved to the engagement position corresponding to the main body. Compared to methods that require relatively large external forces to directly engage the first fastener of the spray head assembly with the liquid storage assembly along the axial direction of the liquid storage assembly, and to engage the second fastener with the main body along the axial direction of the main body, this reduces the risk of damage to the first fastener, the second fastener, the liquid storage assembly, and the corresponding fastener on the main body during the engagement process. Furthermore, compared to screw-in connection methods, the screw-in path can be shortened, enabling rapid installation and replacement of the main body, spray head assembly, and liquid storage assembly.

[0022] In related technologies, if atomizing medium remains inside the spray head assembly of an electronic atomizer, the following two problems are likely to occur. First, if the atomizing medium remains inside the spray head assembly for a long time, it will solidify, causing clogging of the spray head assembly and making it unusable. Second, if the atomizing medium remaining inside the spray head assembly is in contact with air for a long time, microorganisms will easily multiply, causing the atomizing medium to become contaminated and deteriorate. Furthermore, problems such as odor and skin irritation from contact with the deteriorated atomizing medium may occur.

[0023] Based on this, the embodiments of this application provide an electronic atomizing device in which the spray head assembly is detachably connected to the liquid storage assembly / or main body, thereby facilitating the replacement and periodic maintenance of the spray head assembly. Furthermore, if atomizing medium remains in the spray head assembly and causes nozzle clogging or if the remaining atomizing medium deteriorates, only the spray head assembly can be replaced or maintained, without damaging the liquid storage assembly and / or main body, thus solving the problems of nozzle clogging and deterioration of the atomizing medium caused by the atomizing medium remaining in the spray head assembly.

[0024] The present application will be described in detail below in conjunction with the attached drawings and embodiments.

[0025] Please refer to Figures 1a and 2. Figure 1a is a schematic diagram of the overall configuration of an electron atomizing device according to one embodiment of this application, Figure 1b is a cross-sectional view AA of the electron atomizing device shown in Figure 1a according to one embodiment of this application, and Figure 2 is an enlarged view of M in Figure 1b. This embodiment provides an electron atomizing device for atomizing an atomizing medium to form an aerosol. This electron atomizing device can be used specifically in technical fields such as medicine, beauty, health, and electron atomization. Here, the atomizing medium can be a liquid matrix such as oils with added fragrance components or medicinal solutions.

[0026] As shown in Figure 1b, this electronic atomizer comprises a main body 1, a liquid storage assembly 2, and a spray head assembly 3. The liquid storage assembly 2 is located inside the main body 1 and has a liquid outlet 21 (see Figure 4 below). The liquid storage assembly 2 is for storing the atomizing medium, or the atomizing medium is stored in the liquid storage assembly 2 and flows out through the liquid outlet 21 of the liquid storage assembly 2. In one specific embodiment, with reference to Figures 3 and 4, Figure 3 is a schematic diagram of the overall configuration after the spray head assembly and liquid storage assembly are connected according to one embodiment of the present application, and Figure 4 is a cross-sectional view BB of Figure 3. The liquid storage assembly 2 includes a liquid storage case 22, a sealing member 23, and a fixing member 24. The liquid storage case 22 is used to form a liquid storage tank having a liquid outlet 21 at one end along its axial direction Y. The sealing member 23 and the fixing member 24 can be manufactured as a single integrated part and are provided at the other end of the liquid storage tank, and are used to seal the atomizing medium inside the liquid storage tank, the atomizing medium may flow out of the liquid storage tank through the liquid outlet 21, and the atomizing medium may be injected into the liquid storage tank through the liquid outlet 21. Here, the sealing member 23 and the fixing member 24 can be provided in the liquid storage tank so as to be axially movable from the other end of the liquid storage tank, thereby realizing active liquid supply of the liquid storage assembly 2, in this embodiment the body 1 includes a drive member, which is connected to the fixing member 24 of the liquid storage assembly 2 and is used to provide thrust to move the fixing member 24, for example, toward the liquid outlet 21, and drives the atomizing medium to flow out of the liquid storage tank through the liquid outlet 21. Of course, for the liquid in the liquid storage assembly 2, a passive liquid supply method can be used, that is, it can be realized by the gas siphon effect.

[0027] The spray head assembly 3 has a liquid inlet 31, which communicates with the liquid storage assembly 2 and is used to atomize the atomizing medium to form an aerosol. Here, the spray head assembly 3 has a first fastener 32 and / or a second fastener 33, the first fastener 32 is for rotating along the circumferential direction of the spray head assembly 3 until it engages with the liquid storage assembly 2, thereby enabling a detachable connection between the spray head assembly 3 and the liquid storage assembly 2. Here, after the first fastener 32 is rotatably connected to the spray head assembly 3, the liquid outlet 21 and the liquid inlet 31 are connected. The second fastener 33 is for rotating along the circumferential direction of the spray head assembly 3 until it engages with the body 1, thereby enabling a detachable connection between the spray head assembly 3 and the body 1. Here, regarding the rotational connection between the spray head assembly 3 and the liquid storage assembly 2, it is possible to choose to keep the liquid storage assembly 2 stationary and rotate the spray head assembly 3, or to keep the spray head assembly 3 stationary and rotate the liquid storage assembly 2, or to rotate both the liquid storage assembly 2 and the spray head assembly 3 simultaneously, but in this application, the application is not limited to these options, and it is sufficient to achieve a rotational connection between the liquid storage assembly 2 and the spray head assembly 3. The rotational connection between the spray head assembly 3 and the main body 1 is similar to this. The following embodiments in this application all take the example of rotating the spray head assembly 3.

[0028] As described above, by detachably connecting the spray head assembly 3 to the liquid storage assembly 2 and / or the main body 1, replacement and periodic maintenance of the main body 1, spray head assembly 3, and liquid storage assembly 2 become easier. Furthermore, if atomizing medium remains in the spray head assembly 3 and clogs the nozzle 35, or if the remaining atomizing medium deteriorates, only the spray head assembly 3 can be replaced or maintained, without damaging the liquid storage assembly 2 and / or the main body 1, thus solving the problem of nozzle clogging or deterioration of the atomizing medium caused by residual atomizing medium in the spray head assembly 3. Simultaneously, the rotary mechanism allows the first fastener 32 to be aligned with the corresponding position on the liquid storage assembly 2, thereby achieving engagement between the two, and the second fastener 33 to be aligned with the corresponding position on the main body 1, thereby achieving engagement between the two. This allows the first fastener 32 to be smoothly moved to the engagement position corresponding to the liquid storage assembly 2, and the second fastener 33 to be smoothly moved to the engagement position corresponding to the main body 1. Compared to a method that requires a relatively large external force to directly engage the first fastener 32 of the spray head assembly 3 with the liquid storage assembly 2 along the axial Y of the liquid storage assembly 2, and to engage the second fastener 33 with the main body 1 along the axial Y of the main body 1, this reduces the risk of damage to the first fastener 32, the second fastener 33, the liquid storage assembly 2, and the corresponding fasteners on the main body 1 during the engagement process. Furthermore, compared to a screw-in connection method, the screw-in path can be shortened, enabling rapid installation and replacement of the main body 1, spray head assembly 3, and liquid storage assembly 2.

[0029] In one embodiment, with reference to Figures 5 to 8, Figure 5 is a schematic diagram of the configuration of a spray head assembly according to one embodiment of the present application at a first viewing angle, Figure 6 is a CC cross-sectional view of the spray head assembly shown in Figure 5, Figure 7 is a schematic diagram of the configuration of a liquid storage assembly according to one embodiment of the present application, and Figure 8 is a partial schematic diagram of a liquid storage assembly according to one embodiment of the present application. The spray head assembly 3 has a first fastener 32, and the liquid storage assembly 2 has a third fastener 25, and the first fastener 32 rotates along the circumferential direction of the spray head assembly 3 to a position where the third fastener 25 is located and engages with the third fastener 25.

[0030] Here, as shown in Figure 6, the spray head assembly 3 further includes a base body 34, and the first fastener 32 includes a spray head connector 32a and a flange portion 32b. The spray head connector 32a is connected to the base body 34, and the flange portion 32b is connected to the side of the spray head connector 32a and is spaced apart from the base body 34. Here, the base body 34, the spray head connector 32a and the flange portion 32b may be integrally molded.

[0031] As shown in Figures 7 and 8, the third fastener 25 includes a liquid storage connection portion 25a and an engaging portion 25b, the liquid storage connection portion 25a being connected to the liquid storage case 22, the engaging portion 25b being connected to one end of the liquid storage connection portion 25a away from the liquid storage case 22, extending in a direction perpendicular to the axial direction Y of the liquid storage case 22, and defining a U-shaped groove 26 together with the engaging portion 25b and the liquid storage case 22, the flange portion 32b rotating into the U-shaped groove 26 and engaging with the liquid storage assembly 2.

[0032] In one specific embodiment, in combination with Figures 5 and 7, the first fastener 32 and the third fastener 25 are both arc-shaped, and the first fastener 32 is installed around the liquid inlet 31 of the spray head assembly 3, and the third fastener 25 is installed around the liquid outlet 21. In this specific embodiment, the engaging portion 25b specifically extends circumferentially around the liquid storage connection portion 25a and projects toward the liquid storage connection portion 25a toward the liquid outlet 21, defining a slide groove that extends circumferentially around the liquid outlet 21 together with the liquid storage case 22 and the liquid storage connection portion 25a. The above-mentioned U-shaped groove 26 means that the longitudinal cross-section of this slide groove is U-shaped, and it is understood that the liquid storage case 22 and the engaging portion 25b form the two opposing side walls of this U-shaped groove 26, and the liquid storage connection portion 25a forms the bottom wall of this U-shaped groove 26. After the first fastener 32 rotates and enters the U-shaped groove 26, the liquid storage case 22 and the engaging portion 25b engage with the first fastener 32 along the axial direction Y of the liquid storage case 22, thereby connecting the spray head assembly 3 and the liquid storage assembly 2.

[0033] Specifically, the first fastener 32 is formed on the side of the spray head assembly 3 facing the liquid storage assembly 2, and the third fastener 25 is formed on the side of the liquid storage assembly 2 facing the spray head assembly 3. This prevents the first fastener 32 and the third fastener 25 from damaging other elements of the electronic atomizer or affecting the attachment of other elements, is advantageous for achieving miniaturization of the spray head assembly 3 and the liquid storage assembly 2, and results in a relatively aesthetically pleasing overall appearance of the electronic atomizer.

[0034] However, in the above-described installation, during the rotational connection of the spray head assembly 3 and the liquid storage assembly 2, the user cannot clearly see the relative positions of the first fastener 32 and the third fastener 25. In other words, the user cannot know whether the first fastener 32 has rotated to a position opposite the third fastener 25. Thus, the first fastener 32 and the third fastener 25 are offset along the circumferential direction of the spray head assembly 3, which can easily lead to problems such as an unstable connection between the spray head assembly 3 and the liquid storage assembly 2, and the liquid outlet 21 and liquid inlet 31 being misaligned, which can cause liquid leakage.

[0035] Therefore, in some embodiments, in combination with Figures 5 to 7, the first fastener 32 has opposing first end m and second end n along its extending direction, and the third fastener 25 has opposing third end p and fourth end q along its extending direction, and the first end m of the first fastener 32 rotates toward the third fastener 25 along the circumferential direction of the spray head assembly 3 and enters into the U-shaped groove 26 of the third fastener 25 and engages with and fixes to the third fastener 25 along the axial direction Y of the body 1. Here, one of the second end n and the fourth end q has a position limiting block 32c, which is located in the rotation path of the first fastener 32 and is used to prevent the first fastener 32 from continuing to rotate in the current rotation direction.

[0036] In this way, during the process in which the spray head assembly 3 and the liquid storage assembly 2 engage by rotation, the position limiting block 32c can limit the rotation angle of the spray head assembly 3 along a predetermined direction. This prevents the rotation from stopping because the rotation angle is too small and the first fastener 32 does not fully enter the third fastener 25, and also prevents the problem of the connection between the spray head assembly 3 and the liquid storage assembly 2 becoming unstable or the liquid outlet 21 and liquid inlet 31 being misaligned and causing liquid leakage if the rotation angle is too large.

[0037] In one specific embodiment, as shown in Figure 5, the position limiting block 32c is specifically formed on the second end n of the first fastener 32, and the position limiting block 32c abuts against the third end p of the third fastener 25 to prevent the first fastener 32 from continuing to rotate in the current direction of rotation. Specifically, in combination with Figure 5, the position limiting block 32c is formed on the side of the flange portion 32b facing the base body 34.

[0038] Of course, in other embodiments, the position limiting block 32c may be formed on the fourth end q of the third fastener 25, projecting inward into the U-shaped groove 26, and positioned in the rotation path of the first fastener 32, so as to prevent the first fastener 32 from continuing to rotate in its current direction of rotation.

[0039] Here, after the first fastener 32 and the third fastener 25 are engaged, the first fastener 32 rotates in the opposite direction to disengage from the third fastener 25, and further disengages from the third fastener 25, in order to prevent the spray head assembly 3 from falling out of the liquid storage assembly 2. In one embodiment, this is combined with Figures 6 and 8. One of the sides of the first fastener 32 facing the third fastener 25 and the side of the third fastener 25 facing the first fastener 32 has a bump 25c, and the other side has a groove 32d, the bump 25c fits into the groove 32d to fix the relative positions of the first fastener 32 and the second fastener 33 along the circumferential direction of the liquid storage assembly 2.

[0040] Specifically, as shown in Figure 6, the groove 32d is formed near the first end m of the first fastener 32. Specifically, the groove 32d is formed on the side surface of the flange portion 32b facing the base body 34. As shown in Figure 8, the bump 25c is formed near the fourth end q of the third fastener 25.

[0041] In the process of rotating the spray head assembly 3 and the liquid storage assembly 2, first, the liquid outlet 21 of the liquid storage assembly 2 is inserted into the liquid inlet 31 of the spray head assembly 3, and then it is rotated clockwise to align and secure the first fastener 32 and the third fastener 25, and the position is restricted by the position limiting block 32c. If the spray head assembly 3 or the liquid storage assembly 2 needs to be replaced or inspected and repaired, it is simply rotated in the reverse direction.

[0042] In one embodiment, in combination with Figures 5, 6 and 9, Figure 9 is a schematic partial view of the main body according to one embodiment of the present application, wherein the spray head assembly 3 further has a second fastener 33, and the main body 1 has a fourth fastener 11, and the second fastener 33 rotates along the circumferential direction of the spray head assembly 3 to a position where the fourth fastener 11 is located and engages with the fourth fastener 11.

[0043] Specifically, as shown in Figure 5 or Figure 6, there are two second fasteners 33, which are positioned opposite each other on both sides of the liquid inlet 31, with one second fastener 33 located on the side of the first fastener 32 away from the liquid inlet 31, and the other portion of the second fastener 33 projecting away from the liquid inlet 31. In this embodiment, there are also two fourth fasteners 11, which are provided in one-to-one correspondence with the two second fasteners 33, and the fourth fasteners 11 define grooves into which the second fasteners 33 rotate and enter these grooves, thereby defining the relative position between the spray head assembly 3 and the main body 1 along the axial direction Y of the main body 1.

[0044] Here, after the second fastener 33 is rotatably connected to the fourth fastener 11, the second fastener 33 and the fourth fastener 11 are displaced relative to each other to prevent the spray head assembly 3 and the liquid storage assembly 2 from falling from the body 1. In one embodiment, referring to Figures 10 and 11, Figure 10 is a partially schematic diagram of one embodiment of the present application in which the spray head assembly and the body are not yet fully connected, and Figure 11 is a partially schematic diagram of another embodiment of the present application in which the spray head assembly and the body are not yet fully connected, and one of the body 1 and the spray head assembly 3 has an engaging ball 12 and the other has an engaging ball groove 41, and the engaging ball 12 rotates along the circumferential direction of the spray head assembly 3 to a position where the engaging ball groove 41 is located and is fitted into the engaging ball groove 41 to fix the relative position of the body 1 and the spray head assembly 3. It is understood that once the engaging ball 12 is fitted into the engaging ball groove 41, it rotates to a predetermined position and does not need to rotate any further.

[0045] Specifically, as shown in Figure 10, the engagement ball groove 41 is formed on the side of the spray head assembly 3 facing the main body 1. As shown in Figure 11, the engagement ball 12 is formed on the side of the main body 1 facing the spray head assembly 3.

[0046] Referring to Figures 12 to 14, Figures 12 to 13 are schematic diagrams of the assembly process of the electronic atomizer, and Figure 14 is a cross-sectional view of the configuration shown in Figure 13 according to one embodiment of this application. In the specific assembly process, as shown in Figure 12, first the spray head assembly 3 and the liquid storage assembly 2 are rotated together, and then, as shown in Figure 13, the spray head assembly 3 and the liquid storage assembly 2 are inserted into the main body 1 at a predetermined angle, and the second fastener 33 and the fourth fastener 11 are shifted, thus facilitating the rotational connection between the second fastener 33 and the fourth fastener 11. Here, the specific size of the predetermined angle can be determined based on the actual design. Here, after inserting the spray head assembly 3 into the main body 1 at a predetermined angle, the relative positions of the second fastener 33 and the fourth fastener 11 can be seen in Figure 14. Subsequently, as shown in Figure 14, the spray head assembly 3 is rotated in a predetermined direction S to align the second fastener 33 and the fourth fastener 11 along the axial direction Y of the main body 1, and the engaging ball 12 is fitted into the engaging ball groove 41, thereby achieving rotational connection between the spray head assembly 3 and the main body 1. For the configuration after the spray head assembly 3 is connected to the main body 1, please refer to Figure 1a.

[0047] In a specific embodiment, as shown in Figures 1b, 2, and 15, Figure 15 is a cross-sectional view of the electronic atomizer shown in Figure 1a, and the main body 1 further includes an electronic control system 13, a gas pump 14, and gas pipe fittings 15 sequentially connected to the gas pump 14. The electronic control system 13 is for controlling the normal operation of the entire electronic atomizer. The gas pump 14 is for supplying high-pressure gas. The spray head assembly 3 further includes a nozzle 35, a gas seal assembly 36, a liquid outlet seal assembly 37, a gas passage 38, a gas port 39, and a liquid passage 40. One end of the gas passage 38 is connected to the nozzle 35, and the other end of the gas passage 38 is connected to the gas port 39, which is used to connect the gas pipe fittings 15 connected to the main body 1 and to send the high-pressure gas supplied from the gas pump 14 to the nozzle 35. The liquid passage 40 forms a liquid inlet 31 and communicates with the liquid inlet 31 and nozzle 35 of the liquid storage assembly 2, respectively, and is used to deliver the atomizing medium from the liquid storage assembly 2 to the nozzle 35. Here, the high-pressure gas enters the gas passage 38 sequentially from the gas pump 14 through the gas pipe fitting 15 and gas port 39, and finally interacts with the atomizing medium in the nozzle 35 to form an aerosol. The gas seal assembly 36 is for sealing the gas passage 38, and the liquid outlet seal assembly 37 is for sealing the liquid inlet.

[0048] Here, as shown in Figure 16, which is a cross-sectional view of the configuration shown in Figure 13 according to another embodiment of the present application, the gas port 39 and the gas pipe fitting 15 are not connected when the spray head assembly 3 is inserted into the body 1 and not rotated. After rotating by a certain angle, when the second fastener 33 engages with the fourth fastener 11 and is secured, the gas port 39 also rotates and enters the gas pipe fitting 15 of the body 1, supplying gas to the nozzle 35, as shown in Figure 15.

[0049] In this embodiment, the electronic atomizer is fitted with a first fastener 32 and / or a second fastener 33 on the spray head assembly 3. The first fastener 32 rotates along the circumferential direction of the spray head assembly 3 until it engages with the liquid storage assembly 2, thereby achieving a detachable connection between the spray head assembly 3 and the liquid storage assembly 2. The second fastener 33 rotates along the circumferential direction of the spray head assembly 3 until it engages with the main body 1, thereby achieving a detachable connection between the spray head assembly 3 and the main body 1. In this way, replacement and periodic maintenance of the main body 1, spray head assembly 3, and liquid storage assembly 2 are made easy. Furthermore, if atomizing medium remains in the spray head assembly 3 and causes clogging of the nozzle 35 or deterioration of the remaining atomizing medium, only the spray head assembly 3 can be replaced or maintained, eliminating the need to replace the main body 1 and / or liquid storage assembly 2, thus avoiding damage to the liquid storage assembly 2 and / or main body 1, and solving the problems of nozzle clogging and deterioration of the atomizing medium caused by residual atomizing medium in the spray head assembly 3. Simultaneously, the rotary mechanism allows the first fastener 32 to be aligned with the corresponding position on the liquid storage assembly 2, thereby achieving engagement between the two, and the second fastener 33 to be aligned with the corresponding position on the main body 1, thereby achieving engagement between the two. This allows the first fastener 32 to be smoothly moved to the engagement position corresponding to the liquid storage assembly 2, and the second fastener 33 to be smoothly moved to the engagement position corresponding to the main body 1. Compared to a method that requires a relatively large external force to directly engage the first fastener 32 of the spray head assembly 3 with the liquid storage assembly 2 along the axial Y of the liquid storage assembly 2, and to engage the second fastener 33 with the main body 1 along the axial Y of the main body 1, this reduces the risk of damage to the first fastener 32, the second fastener 33, the liquid storage assembly 2, and the corresponding fasteners on the main body 1 during the engagement process. Furthermore, compared to a screw-in connection method, the screw-in path can be shortened, enabling rapid installation and replacement of the main body 1, spray head assembly 3, and liquid storage assembly 2.

[0050] The above are merely embodiments of the present application and do not limit the scope of the patent of this application. For the same reasons, equivalent configurations or equivalent flow transformations made using the contents of the specification and drawings of this application, or those directly or indirectly applicable to other related technical fields, are all included within the scope of the patent protection of this application.
