[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on August 1, 2023, with application number 202322057447.X, and application name “Atomizer and Electronic Atomization Device”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of electronic atomization technology, and in particular to an atomizer and an electronic atomization device. Background Art

[0004] The electronic atomization device is an atomization product that heats a liquid matrix and atomizes it into an aerosol for the user to inhale. A liquid storage chamber is provided in the electronic atomization device to store the liquid matrix, and the liquid storage chamber is sealed by a seal. In the prior art, as shown in the patent with the authorization announcement number CN218354595U and the patent name of atomizer and electronic atomization device, the liquid storage chamber is sealed by a second seal, and the second seal and the suction nozzle are installed separately. The second seal is first installed to the liquid storage part, and then the suction nozzle is pressed onto the second seal and assembled with the liquid storage part. Since the installation of the seal and the suction nozzle is performed by the user during use, the liquid storage chamber is first injected into the liquid storage chamber and then the seal and the suction nozzle are installed for sealing. Therefore, the way of installing the second seal and the suction nozzle separately in the comparative document will result in cumbersome installation steps when the user installs it.

[0005] Furthermore, the reference document employs a sealing method that inserts a second seal into the liquid storage chamber, radially sealing the liquid storage chamber through the second seal, and simultaneously uses a suction nozzle to axially limit the second seal to form an axial seal. This axial sealing method is prone to seal failure when encountering irregularly shaped liquid storage portions, leading to leakage. Meanwhile, a sealing method that presses the second seal into the liquid storage chamber for radial sealing can result in severe fluid pressure and leakage.

[0023] The aforementioned atomizer incorporates a sealing member mounted on the mouthpiece, forming a single assembly with the nozzle.

DETAILED DESCRIPTION

[0035] To facilitate understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments are intended only to explain the present application and are not intended to limit the present application. In addition, it should be noted that, for ease of description, the accompanying drawings only illustrate some structures relevant to the present application, not all structures.

[0036] 1 to 7 , the atomizer 100 includes a liquid storage portion 110 , an atomizing element 120 , a sealing element 130 , and a mouthpiece 140 .

[0037] As shown in Figures 2 and 7, a liquid storage cavity 111 is defined within the liquid storage portion 110. The liquid storage cavity 111 is used to store a liquid matrix. An injection port 112 and a liquid outlet 113 are provided at opposite ends of the liquid storage portion 110. The injection port 112 and the liquid outlet 113 are both connected to the liquid storage cavity 111. As shown in Figure 7, the injection port 112 and the liquid outlet 113 are respectively provided at both ends of the liquid storage portion 110 in the longitudinal direction. The injection port 112 is used to inject the liquid matrix into the liquid storage cavity 111. The liquid outlet 113 is used to allow the liquid matrix in the liquid storage cavity 111 to flow out. The liquid matrix in the liquid storage cavity 111 flows from the liquid outlet 113 to the atomizer 120. The atomizer 120 is provided adjacent to the liquid outlet 113, and the atomizer 120 heats and atomizes the liquid matrix to form an aerosol. The liquid matrix may include, for example, one or more components such as glycerin, propylene glycol, nicotine preparations, flavors and fragrances, flavor additives, etc., and may also be other types of liquid matrices.

[0038] As shown in Figure 2 , the seal 130 is used to seal the liquid injection port 112. As shown in Figures 2 and 4 , the seal 130 includes a radially outwardly extending flange 131. The flange 131 abuts against the end face A of the liquid storage portion 110 adjacent to the liquid injection port 112, thereby allowing the seal 130 to cover the liquid injection port 112 and seal the liquid storage chamber 111. The flange 131 abuts against the end face A of the liquid injection port 112 to seal the liquid storage chamber 111, thus forming an end face sealing structure. The seal 130 can then be tightened by the nozzle assembly 140.

[0039] In the embodiment of the present application, the sealing member 130 is disposed on the mouthpiece 140. That is, the sealing member 130 and the mouthpiece 140 are pre-assembled into a single assembly and then mounted on the liquid reservoir 110. During use, after the liquid matrix is ​​injected into the liquid reservoir 111, the pre-assembled mouthpiece 140 and sealing member 130 can be directly mounted on the liquid reservoir 110, without having to separately mount the sealing member 130 and the mouthpiece 140 on the liquid reservoir 110. This reduces the number of installation steps, facilitates the user's installation operation after liquid injection, and also reduces the chance of installation errors.

[0040] As shown in FIG2 , the nozzle piece 140 is covered on the liquid storage portion 110 by the top end of the liquid storage portion 110. One end of the nozzle piece 140 is open, and the liquid storage portion 110 extends into the nozzle piece 140 from the open end of the nozzle piece 140. The shell of the outer periphery of the nozzle piece 140 surrounds and covers a portion of the outer surface of the liquid storage portion 110, and a sealing ring 145 is provided between the nozzle piece 140 and the liquid storage portion 110. The sealing ring 145 is provided between the inner side wall of the nozzle piece 140 and the outer side wall of the liquid storage portion 110.

[0041] Continuing with Figure 2 , the nozzle assembly 140 is connected to the liquid reservoir 110 via a snap-fit ​​structure, thereby securing the nozzle assembly 140 to the liquid reservoir 110. The snap-fit ​​structure provides longitudinal tension to the nozzle assembly 140, thereby pressing the flange 131 of the sealing member 130 against the liquid reservoir 110, ensuring the sealing effectiveness of the sealing member 130.

[0042] Specifically, as shown in FIG2 , the buckle structure is located on the inner side of the nozzle member 140. A buckle 146 is provided on the inner side wall of the nozzle member 140, and a buckle 116 is provided on the outer side wall of the liquid storage portion 110. The buckle 116 and the buckle 146 cooperate to form a buckle structure, thereby securing the nozzle member 140 to the liquid storage portion 110. The buckle 146 on the nozzle member 140 is provided on the inner side of the nozzle member 140, so that the buckle position is hidden inside the nozzle member 140, forming a non-detachable connection structure between the nozzle member 140 and the liquid storage portion 110, thereby enhancing the sealing effectiveness of the sealing member 130.

[0043] At the same time, after the suction nozzle 140 and the liquid storage part 110 are connected through the above-mentioned snap structure, a non-detachable connection is formed. The suction nozzle 140 is installed to the liquid storage part 110 and cannot be removed from the liquid storage part 110, thereby ensuring the safety performance of the atomizer and preventing it from being accidentally opened by a child and causing the liquid matrix to flow out.

[0044] As shown in FIG. 2 , the buckle structure is closer to the open end of the nozzle member 140 than the sealing ring 145 .

[0045] As shown in Figures 2 and 6, a pressing portion 141 is provided on the suction nozzle 140. The pressing portion 141 abuts against the side of the flange 131 facing away from the liquid storage portion 110 in the direction approaching the liquid storage portion 110 to press the flange 131 against the end face A of the liquid storage portion 110. The longitudinal projection of the pressing portion 141 at least partially overlaps with the end face A of the liquid storage portion 110, thereby pressing the flange 131 against the end face A of the liquid injection port 112 to form an end face seal. Compared with the axial and radial sealing methods described in the background art, the end face seal is more reliable and more effective. At the same time, it can also reduce the amount of liquid pressure during injection.

[0046] Optionally, the projection of the pressing portion 141 in the longitudinal direction covers the end surface A of the liquid storage portion 110. The projection of the pressing portion 141 in the longitudinal direction completely covers the end surface A of the liquid storage portion 110, so that the entire end surface of the liquid storage portion 110 is pressed by the pressing portion 141, and the sealing effect is better.

[0047] 4 , the sealing member 130 further includes a boss 132. As shown in FIG2 , the boss 132 extends from one side of the flange 131, and the boss 132 at least partially extends into the liquid storage chamber 111. The boss 132 can play a positioning role to prevent the sealing member 130 from shifting.

[0048] Optionally, the width of the boss 132 is smaller than the width of the liquid injection port 112, or the diameter of the boss 132 is smaller than the diameter of the liquid injection port 112. When the boss 132 is cylindrical, the diameter of the boss 132 is smaller than the diameter of the liquid injection port 112. When the boss 132 is not cylindrical but has other shapes, the width of the boss 132 is set to be smaller than the width of the liquid injection port 112. In short, the cross-sectional dimensions of the boss 132 are smaller than the dimensions of the liquid injection port 112, so that the size of the boss 132 is smaller than the size of the liquid injection port 112, so that the boss 132 does not fit too tightly with the liquid injection port 112, and there may even be a gap. This can reduce the air compression of the liquid storage chamber 111 during the process of the boss 132 extending into the liquid storage chamber 111 during assembly. If there is an interference fit between the boss 132 and the inner wall of the liquid storage chamber 111, for example, in the prior art described in the background technology, a radial seal is formed by interference fitting the seal 130 with the liquid storage chamber 111. In this way, compressed air may be introduced during the installation of the seal 130 into the liquid storage chamber 111, and the excessive pressure in the liquid storage chamber 111 may squeeze the liquid matrix outward.

[0049] Optionally, as shown in FIG4 , the outer sidewall of boss 132 is provided with a venting groove 1321, which extends longitudinally and terminates at flange 131. When boss 132 extends into liquid reservoir 111, venting groove 1321 on boss 132 serves to vent air during assembly, preventing difficulty in inserting boss 132 into liquid reservoir 111 and facilitating smoother assembly. It will be appreciated that the end of venting groove 1321 extends through the end surface of boss 132, allowing gas within venting groove 1321 to be discharged through the end surface.

[0050] 2 , 5 and 6 , one of the sealing member 130 and the suction nozzle member 140 is provided with a pin 142 and the other is provided with a slot 133. As shown in FIG2 , the pin 142 is inserted into the slot 133, and the pin 142 and the slot 133 are interference fit, so that the sealing member 130 is fixed to the suction nozzle member 140 to form a whole, which can reduce the assembly steps.

[0051] In the embodiment of the present application, as shown in FIG. 2 , the plug post 142 is provided on the nozzle member 140 , and the slot 133 is provided on the sealing member 130 .

[0052] Further, as shown in FIG5 , a latch 134 is provided in the slot 133, and as shown in FIG6 , a socket 143 is provided on the post 142. As shown in FIG3 , the latch 134 is inserted into the socket 143, and the latch 134 and the socket 143 form an interference fit, further connecting the seal 130 to the nozzle 140 and enhancing the connection strength between the two. In other words, the fit between the post 142 and the slot 133, and the fit between the latch 134 and the socket 143 form two connections, tightly connecting the seal 130 to the nozzle 140.

[0053] In the embodiment of the present application, as shown in FIG2 , the pin 142 is provided on the suction nozzle 140, and the slot 133 is provided on the sealing member 130. The slot 133 extends from the end surface of the sealing member 130 away from the liquid storage chamber 111 to the end surface of the boss 132. That is, the slot 133 is provided on the back of the boss 132 and extends into the boss 132. As shown in FIG2 , the bottom B of the slot 133 is lower than the end surface A of the liquid injection port 112, so that after the pin 142 is inserted into the slot 133, the end of the pin 142 inserted into the slot 133 is lower than the end surface A of the liquid injection port 112, that is, in the longitudinal direction, the pin 142 extends into the liquid storage chamber 111. In this way, the pin 142 can be used to fix the boss 132 to a certain extent. Since the sealing member 130 is generally made of rubber or silicone, the material is relatively soft and easily deformed. The plug post 142 on the nozzle piece 140 is used to fix the boss 132 to a certain extent, thereby preventing the boss 132 from deforming, thereby achieving a better limiting effect of the boss 132 in the liquid injection port 112.

[0054] As shown in Figures 2 and 7, an air outlet duct 114 is provided in the liquid storage portion 110. The air outlet duct 114 is arranged in parallel with the liquid storage chamber 111, and the air outlet duct 114 is arranged on both sides of the liquid storage chamber 111. As shown in Figure 7, an atomization chamber 115 is provided in the liquid storage portion 110, and the atomization chamber 115 is used to atomize the liquid matrix for the atomization member 120. As shown in Figure 7, one end of the air outlet duct 114 is connected to the atomization chamber 115, and the other end passes through the end face of the liquid storage portion 110 provided with the liquid injection port 112. It can be understood that, as shown in Figure 2, the air outlet duct 114 is connected to the suction nozzle 144 of the suction nozzle member 140, thereby forming an air outlet duct.

[0055] As shown in FIG. 2 , the edge of the pressing portion 141 of the nozzle piece 140 and the edge of the sealing member 130 are substantially flush with the side wall of the air outlet duct 114 , thereby avoiding the air outlet duct 114 and preventing interference with the outflow of the air flow.

[0056] As shown in FIG. 2 , the top surface C of the pressing portion 141 of the nozzle piece 140 is an inclined surface. The inclined direction can guide the airflow from the air outlet 114 to the nozzle opening 144 of the nozzle piece 140 , thereby facilitating the outflow of airflow.

[0057] The present application also provides an electronic atomization device 200. As shown in FIG8 , the electronic atomization device 200 includes the aforementioned atomizer 100 and a battery assembly 210. The battery assembly 210 is used to power the atomizer 100. When powered on, the atomizer 100 heats and atomizes the liquid matrix, forming an aerosol for the user to inhale.

[0058] As shown in the left image of Figure 9 , when the electronic atomization device 200 of the present embodiment is manufactured, the sealing member 130 is assembled into the mouthpiece 140 to form a single assembly. During use, the user simply fills the liquid reservoir 110 with liquid and then snaps the mouthpiece 140 onto the liquid reservoir 110, completing the installation. The completed installation is shown in the right image of Figure 9 .

For example, it can mean fixed connection, detachable connection, or integration; it can mean direct connection or indirect connection through an intermediate medium.
