Detailed Description

In order that the utility model may be readily understood, a more particular description thereof will be rendered by reference to specific embodiments that are illustrated in the appended drawings. The specific examples are intended to be illustrative of the utility model and are not intended to be limiting. In addition, for convenience of description, only some, but not all of the structures related to the present utility model are shown in the drawings.

The embodiment of the utility model provides an atomizer. Referring to fig. 1-5, there is shown a schematic diagram of an electronic atomizing device 200 incorporating an atomizer 100 embodying the present utility model. As shown in fig. 4, the atomizer 100 includes a liquid storage chamber 110, a ventilation passage 120, a liquid outlet 131, and a heating member 140.

The reservoir 110 is used to store a liquid matrix. The liquid matrix can mainly comprise one or more of glycerol, propylene glycol, nicotine preparation, essence, perfume, flavor additive and the like, and can also comprise other components, and the liquid matrix can be specifically selected according to the needs.

As shown in fig. 4, the ventilation channel 120 communicates the liquid storage chamber 110 with the outside for providing a path for external air to enter the liquid storage chamber 110. When the negative pressure in the liquid storage cavity 110 reaches a certain degree, air is introduced into the liquid storage cavity 110 through the air exchange channel 120 to exchange air, so as to balance the negative pressure in the liquid storage cavity 110. The "outside" may be any other chamber of the atomizer 100 than the liquid storage chamber 110, such as an atomizing chamber, or may be any outside of the atomizer 100, so long as ventilation of the liquid storage chamber 110 is possible.

As shown in fig. 4, the liquid outlet 131 is disposed at one end of the liquid storage cavity 110 along the longitudinal direction thereof, so that the liquid outlet 131 is disposed at the bottom end of the liquid storage cavity 110, so that the liquid matrix in the liquid storage cavity 110 can flow out from the liquid outlet 131 under the action of gravity.

Referring to fig. 4, the heating member 140 serves to heat the liquid matrix to form an aerosol. The heating element 140 is in fluid communication with the outlet 131, thereby receiving liquid matrix from the liquid reservoir 110 through the outlet 131.

As shown in fig. 4, the ventilation channel 120 includes a ventilation port 121 located in the liquid storage cavity 110, in an embodiment of the utility model, referring to fig. 5, the ventilation port 121 is spaced from the liquid outlet 131, and a blocking wall 150 is disposed between the ventilation port 121 and the liquid outlet 131 to block bubbles generated by the ventilation port 121 from escaping and moving to the liquid outlet 131.

In the atomizer 100 of the above embodiment, the ventilation port 121 and the liquid outlet 131 are arranged at intervals, so that the ventilation port 121 is far away from the liquid outlet 131, and the liquid outlet 130 is prevented from being blocked by bubbles entering the liquid outlet 131 from the ventilation port 121 as much as possible, so that the normal liquid outlet of the liquid outlet 131 is ensured, the sufficient liquid substrate is ensured to flow to the heating element 140, and the heating element 140 is prevented from dry burning. Meanwhile, in the atomizer 100 of the embodiment of the present utility model, a blocking wall 150 is disposed between the ventilation port 121 and the liquid outlet 131, the blocking wall 150 can block bubbles of the ventilation port 121 from flowing to the liquid outlet 131, and limit bubbles generated by ventilation to travel only in a longitudinal direction, so that the bubbles float vertically upwards, further preventing bubbles from accumulating in the liquid outlet 131, and further avoiding the dry burning of the heating element 140 from generating burnt smell.

As shown in fig. 5, the atomizer 100 further includes an inner sidewall 111 and an inner bottom wall 112 that at least partially define the boundaries of the reservoir 110. The ventilation port 121 and the liquid outlet 131 are provided on the inner bottom wall 112. Providing the ventilation ports 121 on the inner bottom wall 112 may reduce the sidewall thickness of the atomizer 100 relative to providing the ventilation ports 121 on the inner sidewall 111.

As shown in fig. 5, the blocking wall 150 extends from the inner bottom wall 112 toward the inside of the liquid storage chamber 110 in the longitudinal direction. This causes the bubbles to travel longitudinally upward, toward the upper portion of the liquid matrix, away from the liquid outlet 131.

In one embodiment, as shown in FIG. 6, the baffle wall 150 surrounds the ventilation port 121 to form a drainage channel a for guiding the flow of bubbles. The drainage channel a encloses and guides the air bubble upwards, and further limits the movement of the air bubble to the liquid storage port.

Specifically, as shown in fig. 6, the blocking wall 150 may form a drainage channel a together with the inner sidewall 111 of the liquid storage cavity 110, or the blocking wall 150 may be formed into a channel shape alone to form the drainage channel a.

As shown in fig. 3, 4 and 8, the atomizer 100 further includes a mounting base 160 and a seal 170. Referring to fig. 4 and 7, the liquid storage chamber 110 and the ventilation channel 120 are disposed on the mounting substrate 160. As shown in fig. 4, the mounting base 160 is provided with a liquid outlet 130, a port of the liquid outlet 130 in the liquid storage cavity 110 is a liquid outlet 131, and the other end of the liquid outlet 130 extends to the heating element 140, so as to guide the liquid substrate in the liquid storage cavity 110 to the heating element 140. The heating member 140 is mounted on the mounting base 160 with one side facing the liquid outlet 131.

As shown in fig. 3, the heating member 140 may include a porous body 141 and a heating wire 142, and the heating wire 142 is coupled to a side of the porous body 141 remote from the liquid outlet hole 130. As shown in fig. 3, the top of the porous body 141 is in fluid connection with the outlet aperture 130, and the porous body 141 receives the liquid matrix from the liquid reservoir 110 through the outlet aperture 130. The heating wire 142 is combined at the bottom of the porous body 141, and the heating wire 142 can heat the liquid matrix in the porous body 141 after being electrified and heated to form aerosol. The bottom of the porous body 141 faces the liquid outlet 131. By providing corresponding air inlet and outlet passages in the atomizer 100, aerosol is output, which can be sucked out when the user sucks.

A seal 170 is provided on the mounting base 160, the seal 170 being used to provide a seal between the heating element 140 and the mounting base 160.

Fig. 9 to 11 are combined. The mounting base 160 has a mounting end face 161 for mounting the seal 170. Ventilation channel 120 includes a first airway segment 120a and a second airway segment 120b. The first airway segment 120a communicates with the second airway segment 120b. As shown in fig. 11, the first air passage section 120a extends from the reservoir 110 toward the mounting end surface 161. The second air passage section 120b is a groove provided on the mounting end surface 161. Providing the groove-shaped second airway segment 120b on the mounting end face 161 facilitates the introduction of airflow into the ventilation channel 120 from an area outside the end face area covered by the seal 170.

As shown in fig. 4, the size of the groove-shaped second air passage section 120b may be set smaller than the size of the first air passage section 120a. The second airway segment 120b is sized smaller to prevent leakage. In practice, the first airway segment 120a is also provided with a smaller size that is not accessible by the liquid matrix, but to further prevent leakage, the second airway segment 120b may be sized smaller than the first airway segment 120a. In fact, referring to FIG. 4, the first air passage section 120a is in the shape of a hole provided in the mounting base 160. With the above design, the second air passage section 120b with smaller size is provided to further prevent leakage, and the first air passage section 120a with slightly larger size than the second air passage section 120b is provided to store sufficient air, so as to ensure smooth ventilation operation.

As shown in fig. 7 and 10, seal 170 covers at least a portion of second airway segment 120b, and in conjunction with fig. 9, the portion of second airway segment 120b that is covered by seal 170 includes the junction of second airway segment 120b with first airway segment 120a. Covering the second airway segment 120b with the seal 170 ensures both tightness of the ventilation channel 120 and smooth air intake of the ventilation channel 120.

As shown in fig. 9, the mounting end surface 161 includes a first end surface 161a and a second end surface 161b. The first end surface 161a and the second end surface 161b are connected and perpendicular to each other. The first end surface 161a extends in the lateral direction, and the second end surface 161b extends in the longitudinal direction. The second airway segment 120b is disposed on the first end face 161a and the second end face 161b. As shown in fig. 9, the first airway segment 120a intersects the first end surface 161a to form a port from which the second airway segment 120b extends along the first end surface 161a, to the second end surface 161b, and continues down the second end surface 161b. As shown in fig. 10, the top end of seal 170 abuts first end face 161a, thereby covering a portion of second airway segment 120b.

In other embodiments, the side wall of the sealing member 170 may also abut against the second end surface 161b, and since the second air passage section 120b extends to the bottom end of the second end surface 161b, even if the side wall of the sealing member 170 abuts against the second end surface 161b to cover the second air passage section 120b on the second end surface 161b, the second air passage section 120b can be ensured to be able to enter from the port of the second air passage section 120b, without affecting the air intake of the second air passage section 120b.

In other embodiments, ventilation channel 120 may not include second airway segment 120b, but may include only first airway segment 120a. That is, the ventilation channel 120 extends from the reservoir 110 toward the mounting end 161, and the ventilation channel 120 is only one ventilation hole extending from the reservoir 110 toward the mounting end 161. The seal 170 covers a portion of the port of the ventilation channel 120 located on the mounting end face 161, and the seal 170 covers a portion of the port of the ventilation channel 120, leaving a portion uncovered for air intake.

In one embodiment, as shown in fig. 10 and 12, the seal 170 includes a body portion 171 and a ledge 172. The body portion 171 is annular, the annular body portion 171 surrounds the outlet opening 130, and the body portion 171 provides a seal between the heating element 140 and the mounting base 160. A ledge 172 extends from the body portion 171 to the periphery of the seal 170. The lugs 172 are used to cover at least a portion of the second airway segment 120b, or to cover portions of the ports of the ventilation channel 120 located on the mounting end face 161.

As described above, the ventilation channel 120 may include the first air channel section 120a and the second air channel section 120b, or may be just one ventilation hole extending from the liquid storage chamber 110 toward the mounting end surface 161. When ventilation channel 120 includes first and second airway segments 120a and 120b, lugs 172 are configured to cover at least a portion of second airway segment 120b, including where second airway segment 120b joins first airway segment 120a. When the ventilation channel 120 is only one ventilation aperture extending from the reservoir 110 to the mounting end 161, the lugs 172 serve to cover the portion of the ventilation channel 120 that is located at the port on the mounting end 161.

As shown in fig. 10, the size of the lugs 172 is much smaller than the size of the body portion 171, and the lugs 172 are small extensions of the body portion 171 that extend outwardly. This has the advantage that the second airway segment 120b does not have to extend laterally to a position closer to the edge of the mounting substrate 160. If the second air passage section 120b is covered by the main body portion 172 instead of the smaller-sized lugs 172, the second air passage section 120b must extend laterally to the location of the edge of the mounting base 160 due to the larger size of the main body portion 172.

In addition, providing smaller sized lugs 172 reduces the material of the seal 170, reducing costs. At the same time, the provision of lugs 172 also facilitates positioning of the seal 170 by the lugs 172.

The embodiment of the utility model also provides the electronic atomization device 200. As shown in fig. 3 and 8, the electronic atomizing device 200 includes the atomizer 100 and further includes a mounting base 210. The mount 210 is disposed on the mounting base 160. As shown in fig. 3, the mounting base 210 is spaced apart from the heating member 140 in the longitudinal direction so that an atomizing chamber B is formed between the mounting base 210 and the heating member 140.

As shown in fig. 3, an air inlet 241 is provided at the bottom of the electronic atomizing device 200, an air inlet channel 212 is provided on the mounting base 210, and the atomizing chamber B is communicated with the external atmosphere through the air inlet channel 212 and the air inlet 241, so that the external atmosphere can enter the atomizing chamber B when the user sucks. Referring to fig. 4, the ventilation channel 120 communicates with the atomizing chamber B. When the liquid matrix in the liquid storage cavity 110 is consumed, negative pressure is generated in the liquid storage cavity 110, and under the action of pressure difference, air flow in the atomization cavity B enters the liquid storage cavity 110 from the air exchange channel 120 to complete air exchange. As shown in fig. 7 and 8, the mounting base 160 is provided with an air outlet passage 162, and the atomized aerosol in the atomizing chamber B is delivered through the air outlet passage 162.

As shown in fig. 3, the mounting base 210 is provided with a pole 211, the pole 211 is electrically connected with the heating wire 142 on the heating element 140, and the pole 211 is also electrically connected to the battery 101, so as to supply power to the heating wire 142 through the battery 101.

As shown in fig. 1, the electronic atomizing device 200 further includes a suction nozzle 220, a housing 230, and a bottom cover 240. The mouthpiece 220, housing 230, and bottom cover 240 collectively define an exterior surface of the electronic atomizing device 200. As shown in fig. 3, the suction nozzle 230 is disposed on top of the mounting base 160, the housing 230 is disposed around the outer periphery of the mounting base 160, and the bottom cover 240 is disposed on the bottom of the mounting base 160. The air intake hole 241 is provided on the bottom cover 240.
