[0054] The present application provides an electronic atomization device for atomizing a medium to be atomized to form an aerosol. The electronic atomization device can be applied to the fields of medical treatment, beauty, agriculture, etc. The medium to be atomized can include but is not limited to liquid medicine, nutrient solution, beauty solution, essence, essence milk, disinfectant, insecticide, and pesticide. Figure 1 As shown, the electronic atomization device may include a driving assembly 100 , a housing assembly 200 , an atomization bomb 400 , an atomization assembly 500 and an air supply assembly 600 .

[0055] Combination Figure 3a and Figure 3b Specifically, the housing assembly 200 has a receiving groove 10 and a receiving cavity 30; a guide hole 20 is opened on the top wall of one end of the receiving groove 10 along the axial direction, which is used to provide a guiding function for the driving assembly 100; and the receiving groove 10 is connected with the receiving cavity 30 through the guide hole 20.

[0056] The atomizing bomb 400 is detachably disposed in the receiving chamber 30 of the housing assembly 200, and the atomizing bomb 400 stores the medium to be atomized. The atomizing bomb 400 may include a piston, and the first end of the push rod 1 abuts against the piston; the push rod 1 pushes the piston to push the medium to be atomized in the atomizing bomb 400. Of course, in some other embodiments, the atomizing bomb 400 may also be fixedly disposed in the receiving chamber 30.

[0057] The driving assembly 100 is disposed in the containing groove 10 and is used to push the medium to be atomized in the atomizing bomb 400 ; the driving assembly 100 may include a push rod 1 , a screw rod 2 , and a motor 4 .

[0058] like Figure 2 As shown, the first end of the push rod 1 has a travel switch 11 for detecting whether the push rod 1 is in contact with the atomizing bomb 400; specifically, the travel switch 11 is connected to the motor 4 through the control circuit. When the travel switch 11 detects that the push rod 1 is in contact with the atomizing bomb 400, the control circuit controls the push rod 1 of the driving assembly 100 to stop moving forward and retreat after a preset distance; in response to the user's operation, the push rod 1 continues to move forward and pushes the piston movement of the atomizing bomb 400 to achieve active liquid supply. The screw 2 is threadedly connected to the push rod 1 to drive the push rod 1 to move along the axial direction X; the motor 4 is connected to the screw 2, and the motor 4 drives the push rod 1 to move along the axial direction X through the screw 2; in a specific embodiment, the motor 4 can be connected to the screw 2 through a gear (not shown) or other transmission mechanism.

[0059] The push rod 1 of the driving assembly 100 can slide back and forth in the axial direction in the guide hole 20. The shape of the guide hole 20 matches the outer contour of the main body 12 of the push rod 1; the receiving groove 10, the guide hole 20 and the push rod 1 are coaxially arranged.

[0060] The atomizing assembly 500 is in communication with the atomizing bomb 400 and is used to atomize the medium to be atomized; the atomizing assembly 500 has a spray port for outputting aerosol, so that the aerosol generated in the atomizing assembly 500 can be used by the user.

[0061] The gas supply assembly 600 is used to supply gas to the atomizing assembly 500. The gas supply assembly 600 is connected to the atomizing assembly 500 and is used to provide external gas to the atomizing assembly 500. Specifically, the gas supply assembly 600 can provide high-pressure gas to the atomizing assembly 500, and the high-pressure gas can shear the medium to be atomized entering the atomizing assembly 500 into atomized particles of suitable particle size, i.e., aerosol, and carry the aerosol to be sprayed out from the spray port. Among them, the gas supply assembly 600 can be an air pump.

[0062] A guide hole 20 with a guiding function is opened on the accommodating groove 10, and the guide hole 20 is coaxially arranged with the push rod 1, so that the push rod 1 can slide along the axial direction perpendicular to the rotation direction of the screw 2, thereby avoiding the push rod 1 from deviating during the back-and-forth sliding process; compared with the method of setting a guide rod in the prior art, the guide hole 20 of the electronic atomization device has a simple structure and a small space occupancy rate, which is conducive to the miniaturization of the device; at the same time, it also effectively reduces the manufacturing cost.

[0063] In a specific embodiment, the atomizer assembly 500 may be at least partially located outside the housing; or, the atomizer assembly 500 is disposed inside the housing. When the atomizer assembly 500 is disposed inside the housing, the housing further has a clearance hole, and the spray port of the atomizer assembly 500 is exposed through the clearance hole, so that the aerosol generated in the atomizer assembly 500 can be discharged through the clearance hole for use by the user.

[0064] Of course, in some other embodiments, the atomizing assembly 500 may also include an atomizing element (not shown), which is used to atomize the medium to be atomized to form an aerosol. The atomizing element may be an ultrasonic atomizing element, an electric heating atomizing element, a two-phase flow atomizing nozzle, etc. in the prior art. Specifically, in one embodiment of the present application, the atomizing element is a two-phase flow atomizing nozzle, that is, a high-speed airflow and a liquid are used to generate an aerosol.

[0065] Of course, the electronic atomization device may also include a power supply assembly 700 for supplying power to various structural components of the electronic atomization device. Its structure is the same or similar to the power supply assembly 700 in the prior art. For details, please refer to the prior art and will not be repeated here.

[0066] like Figure 3aAs shown, specifically, the housing assembly 200 may include a housing 21 and a bracket 22. The side wall of the bracket 22 has a receiving groove 10 for receiving the driving assembly 100; the housing 21 and the top wall of the bracket 22 are surrounded to form a receiving cavity 30 for receiving the atomizing bomb 400; the receiving cavity 30 is connected to the receiving groove 10 through the guide hole 20, and the receiving cavity 30 is coaxially arranged with the guide hole 20 and the receiving groove 10, so as to realize the coaxial arrangement of the atomizing bomb 400, the guide hole 20 and the push rod 1.

[0067] Specifically, the accommodating groove 10 may include a first accommodating section 101 and a second accommodating section 102 arranged along the axial direction X; wherein the first accommodating section 101 is connected to the guide hole 20 and is used to accommodate the push rod 1 and the screw rod 2; the second accommodating section 102 is located at an end of the first accommodating section 101 away from the guide hole 20 and is used to accommodate the motor 4. Specifically, the main body 12 of the push rod 1 is accommodated in the first accommodating section 101, and the end 14 of the push rod 1 is exposed into the accommodating cavity 30 through the guide hole 20.

[0068] like Figure 3b As shown, in a specific embodiment, the electronic atomization device may further include a flexible seal 300 disposed on the guide hole 20. Specifically, the flexible seal 300 is sleeved on the circumferential outer side of the main body 12 of the push rod 1; so that when the push rod 1 slides back and forth on the guide hole 20, the flexible seal 300 can separate the receiving groove 10 and the receiving cavity 30 into two independent spaces, so as to prevent the liquid in the receiving cavity 30 from entering the receiving groove 10 and corroding the driving component 100. Specifically, the flexible seal 300 may include a first annular sealing portion disposed on the inner wall surface of the guide hole 20; the inner wall surface of the first annular sealing portion has a first sealing ring 311; the first sealing ring 311 is interference fit with the outer wall of the main body 12 to prevent the liquid on the outer wall of the main body 12 from entering the receiving groove 10. In addition, the first sealing ring 311 further keeps the push rod 1 coaxial with the guide hole 20 during the sliding process by clamping the main body 12 of the push rod 1.

[0069] In a specific embodiment, the surface of the top wall of the accommodating groove 10 facing the accommodating cavity 30 has a sealing groove 40 for accommodating the end 14 of the push rod 1 and the top cover 5; specifically, the sealing groove 40 extends from the top wall of the accommodating groove 10 toward the surface of the accommodating cavity 30 toward the accommodating groove 10; the guide hole 20 is connected to the bottom wall of the sealing groove 40, and the inner wall surface of the guide hole 20 is connected to the bottom wall surface of the sealing groove 40 and is perpendicular to each other.

[0070] Furthermore, the flexible seal 300 may also include a second annular sealing portion disposed on the bottom wall of the sealing groove 40, the second annular sealing portion being connected to the first annular sealing portion, and the second annular sealing portion and the first annular sealing portion being perpendicular to each other. A second sealing ring 321 is provided at the connection between the second annular sealing portion and the first annular sealing portion, and the second sealing ring 321 is interference-fitted with the outer wall of the main body 12, so as to further enhance the sealing and waterproofing effect of the flexible seal 300.

[0071] Specifically, the second sealing ring 321 extends from the corner between the side wall of the guide hole 20 and the bottom wall of the sealing groove 40 into the sealing groove 40, and forms a constriction structure along the extension direction; it should be noted that along the axial direction X, the diameter of the second sealing ring 321 gradually decreases in the direction away from the receiving groove 10. In this way, when the push rod 1 returns to the receiving groove 10, the second sealing ring 321 can block the liquid on the outer wall of the push rod 1 in the sealing groove 40, and prevent it from entering the receiving groove 10 and corroding other structural parts of the drive assembly 100.

[0072] The inner diameter a of the small opening of the second sealing ring 321 is smaller than or equal to the inner diameter b of the first sealing ring 311 , so that the second sealing ring 321 can fit completely with the outer wall of the push rod 1 without leaving any gap, thereby ensuring the scraping effect of the second sealing ring 321 .

[0073] Furthermore, the surface of the top wall of the receiving groove 10 facing the receiving cavity 30 also has an annular protrusion 221 surrounding the sealing groove 40; the inner side wall of the annular protrusion 221 is connected to the side wall of the sealing groove 40 and forms the same curved surface. Correspondingly, the flexible seal 300 may also include a third annular sealing portion provided on the inner side wall and the outer side wall of the annular protrusion 221, and the third annular sealing portion further extends to the side wall of the sealing groove 40 and is connected to the second annular sealing portion.

[0074] Combination Figure 3b and Figure 3c Specifically, the inner side wall of the annular protrusion 221 has a plurality of second grooves 2210 spaced apart along the circumferential direction, and the third annular sealing portion is embedded in the top wall of the accommodating groove 10 through the plurality of second grooves 2210 to fix the flexible seal 300 on the bracket 22 to prevent the flexible seal 300 from falling off during use.

[0075] Furthermore, the top wall of the accommodating groove 10 on the side facing the accommodating cavity 30 also has an annular groove 222 surrounding the annular protrusion 221; correspondingly, the flexible seal 300 can also include a first fixing portion 34 arranged in the annular groove 222, and the first fixing portion 34 is connected to the third annular sealing portion to further fix the flexible seal 300 on the bracket 22.

[0076] The top wall of the accommodating groove 10 has a plurality of fixing grooves 223 on the side facing the accommodating cavity 30, and the plurality of fixing grooves 223 are arranged on the outer side of the annular groove 222 and are connected to the annular groove 222; correspondingly, the flexible seal 300 can also include a second fixing portion (not shown) arranged in the fixing groove 223, and the second fixing portion is connected to the first fixing portion 34 to further fix the flexible seal 300 on the bracket 22.

[0077] In a specific embodiment, Figure 4 As shown, the drive assembly 100 may also include a reduction box 3; the reduction box 3 is connected to the screw 2; the motor 4 is connected to the reduction box 3, and is used to provide rotational power to the screw 2 through the reduction box 3. The motor 4 drives the screw 2 to rotate along the radial direction of the drive assembly 100, and the screw 2 is connected to the push rod 1 through a thread, pushing the push rod 1 to slide along the axial direction X, so as to convert the rotational motion of the screw 2 into the linear motion of the push rod 1. A gear (not shown) is arranged in the reduction box 3, and the end of the screw 2 close to the reduction box 3 is meshed with the gear, and the motor 4 drives the screw 2 to rotate through the gear.

[0078] In a specific embodiment, in combination Figure 4 and Figure 5 The driving component 100 may further include a top cover 5 disposed at the first end, and the top cover 5 covers a travel switch 11 to protect the travel switch 11, thereby preventing the travel switch 11 from being over-squeezed and damaged when the push rod 1 abuts against the atomizer bomb 400 and moves forward; at the same time, it can also prevent liquid from entering the interior of the driving component 100 and corroding the internal structure of the driving component 100.

[0079] Specifically, the top cover 5 may include a first annular side wall 51 and a first top wall 52. The first annular side wall 51 is engaged with the side wall of the push rod 1 to fix the top cover 5 on the push rod 1. The first top wall 52 may include a deformation portion 520; the deformation portion 520 is in contact with or spaced from the travel switch 11 in a natural state; the deformation portion 520 is configured to be deformed under an external force and squeeze the travel switch 11, thereby triggering the travel switch 11.

[0080] In a specific embodiment, the first annular side wall 51 is rigid so that when the deformable portion 520 of the top cover 5 is deformed, the first annular side wall 51 will not be tilted, thereby preventing the top cover 5 from falling off when being squeezed by the atomizer bomb 400 and the push rod 1 .

[0081] Combination Figure 5 and Figure 6, the first top wall 52 may also include a rigid portion 521 and a flexible portion 522. The rigid portion 521 is integrally formed with the first annular side wall 51 and together constitutes a rigid portion of the top cover 5; the rigid portion 521 is annular and has a through hole, and the flexible portion 522 is embedded in the through hole. The flexible portion 522 may include a deformable portion 520; the deformable portion 520 is spaced apart from the travel switch 11, and the deformable portion 520 protrudes toward the side away from the travel switch 11 along the axial direction. It can be understood that when the deformable portion 520 abuts against the atomizing bomb 400, the deformable portion 520 is deformed under the extrusion of the atomizing bomb 400 and presses the travel switch 11 downward, and when the rigid portion 521 abuts against the atomizing bomb 400, the deformation degree of the deformable portion 520 reaches the maximum; in this way, by setting the rigid portion 521, it is possible to avoid the deformation degree of the deformable portion 520 being too large, and excessive extrusion of the travel switch 11 causing structural damage.

[0082] like Figure 6 As shown, specifically, the flexible portion 522 may further include a second annular side wall 5221 and a second top wall 5222. Among them, one of the outer side surface of the second annular side wall 5221 and the inner side surface of the through hole of the rigid portion 521 has a first clamping protrusion 5211, and the other has a first clamping groove 5220; the first clamping protrusion 5211 and the first clamping groove 5220 cooperate with each other to fix the flexible portion 522 on the rigid portion 521. The second top wall 5222 is integrally formed with the second annular side wall 5221; the second top wall 5222 can serve as the deformation portion 520, and protrudes toward the side away from the travel switch 11 along the axial direction.

[0083] In this embodiment, the first locking protrusion 5211 is disposed on the inner side surface of the through hole of the rigid part 521 and extends radially inward from the inner side surface; the first locking groove 5220 is disposed on the outer side surface of the second annular side wall 5221 and extends radially inward from the inner side surface. Of course, in other embodiments, the first locking protrusion 5211 may also be disposed on the outer side surface of the second annular side wall 5221, and correspondingly, the first locking groove 5220 may also be disposed on the inner side surface of the through hole of the rigid part 521.

[0084] like Figure 5 As shown, in a specific embodiment, the top cover 5 may further include an elastic support portion 53 disposed in the top cover 5. One end of the elastic support portion 53 is disposed against the end surface of the first end, and the other end is disposed against the deformation portion 520 to further control the maximum deformation degree of the deformation portion 520. Specifically, the elastic support portion 53 is disposed around the travel switch 11 to avoid affecting the deformation portion 520 from squeezing and triggering the travel switch 11. The material of the elastic support portion 53 may be silicone.

[0085] The deformation part 520 is also configured to squeeze the elastic support part 53 to deform during the process of squeezing the travel switch 11, so that the elastic support part 53 provides a restoring force to the deformation part 520; so that when the atomizer bomb 400 and the push rod 1 are released from contact, the restoring force provided by the elastic support part 53 to the deformation part 520 can make the deformation part 520 restore its deformation, thereby avoiding the situation that the deformation part 520 cannot restore its deformation and affects the normal use of the electronic atomization device.

[0086] Continue reading Figure 5 In a specific embodiment, the push rod 1 may include a main body 12, an end 14 and a nut 13. The main body 12 has a receiving cavity 120 for receiving the screw rod 2; specifically, the receiving cavity 120 passes through the main body 12 along the axial direction X.

[0087] The end portion 14 is connected to one end of the main body 12, and the end portion 14 protrudes from the main body 12 along the radial direction of the push rod 1. It can be understood that the push rod 1 abuts against the atomizing bomb 400 through the end portion 14 to increase the contact area between the push rod 1 and the atomizing bomb 400, thereby improving the pushing stability of the drive assembly 100. The end surface of the end portion 14 has a groove 140, and the travel switch 11 and the elastic support portion 53 are arranged in the groove 140. Specifically, the diameter of the end portion 14 is greater than the diameter of the main body 12, and the end portion 14 is coaxially arranged with the main body 12, and the side wall of the end portion 14 protrudes from the side wall of the main body 12. The top cover 5 is sleeved on the end portion 14, and the first annular side wall 51 of the top cover 5 is clamped with the side wall of the end portion 14.

[0088] The nut 13 is disposed in the accommodating cavity 120 and fixedly connected to the main body 12, and the nut 13 is located at one end of the accommodating cavity 120 away from the end 14. The nut 13 has a through hole, and the nut 13 is sleeved on the circumferential periphery of the screw rod 2 through the through hole; the push rod 1 is threadedly connected to the screw rod 2 through the nut 13. The nut 13 includes a threaded section 131 and a guide section 132.

[0089] Specifically, the threaded segment 131 is spaced apart from the travel switch 11, and the inner wall of the threaded segment 131 has threads and is threadedly connected to the screw 2; the screw 2 rotates in the radial direction, and the friction between the screw 2 and the threaded segment 131 drives the nut 13 to rotate and make a linear motion in the axial direction X, thereby realizing the conversion of the rotational motion of the screw 2 into the linear motion of the push rod 1.

[0090] The guide section 132 is connected to the end of the threaded section 131 close to the travel switch 11 to guide the screw 2, thereby preventing the relative position of the screw 2 and the push rod 1 in the radial direction from shifting during the movement of the push rod 1. The inner wall of the guide section 132 is clearance-matched with the screw 2 to prevent the screw 2 from contacting the inner wall of the guide section 132, thereby effectively reducing the friction between the screw 2 and the nut 13.

[0091] The screw rod 2 is coaxially arranged with the nut 13 and the accommodating chamber 120, so that the push rod 1 can slide along the axial direction perpendicular to the rotation direction of the screw rod 2, thereby preventing the push rod 1 from deviating during the back-and-forth sliding process.

[0092] The present application provides an electronic atomization device, which includes a shell component 200, an atomizer bomb 400, a drive component 100, an atomizer component 500 and an air supply component 600; wherein the shell component 200 has a receiving groove 10 and a receiving cavity 30; a guide hole 20 is opened on the top wall of one end of the receiving groove 10 along the axial direction; and the receiving groove 10 is connected with the receiving cavity 30 through the guide hole 20; the atomizer bomb 400 can be detachably or fixedly arranged in the receiving cavity 30 of the shell component 200 for storing the medium to be atomized; the drive component 100 is arranged in the receiving groove, and the drive component 100 is used to push the mist The drive assembly 100 contains a medium to be atomized in the atomizing bomb 400, and includes: a push rod 1, a screw rod 2 and a motor 4; the first end of the push rod 1 has a travel switch 11 for detecting whether the push rod 1 is in contact with the atomizing bomb 400; the screw rod 2 is connected to the push rod 1, and is used to drive the push rod 1 to move along the axial direction X; the motor 4 is connected to the screw rod 2, and the motor 4 drives the push rod 1 to move through the screw rod 2; the push rod 1 of the drive assembly 100 can slide back and forth in the axial direction in the guide hole 20; the shape of the guide hole 20 matches the outer contour of the main body 12 of the push rod 1; wherein the accommodating groove 10, the guide hole 20 and the push rod 1 are coaxially arranged. A guide hole 20 with a guiding function is opened on the accommodating groove 10, and the guide hole 20 is coaxially arranged with the push rod 1, so that the push rod 1 can slide along the axial direction perpendicular to the rotation direction of the screw 2, thereby avoiding the push rod 1 from deviating during the back-and-forth sliding process; compared with the method of setting a guide rod in the prior art, the guide hole 20 of the electronic atomization device has a simple structure and a small space occupancy rate, which is conducive to the miniaturization of the device; at the same time, it also effectively reduces the manufacturing cost.
