Abstract
Description
Technical Field
[0001] This application relates to the field of atomization technology, and in particular to an electronic atomization device. Background Technology
[0002] High-capacity e-cigarette devices typically include a supply tank, which stores a large amount of e-liquid.

However, manual filling makes it difficult to precisely control the amount of e-liquid added, leading to inconsistent e-liquid levels in the tank. Too much e-liquid in the tank can cause leakage and incomplete atomization, while too little e-liquid can cause the atomizer to burn out. Utility Model Content

[0041] This application discloses an electronic atomizing device, which includes an oil storage tank, an atomizing component, an oil supply tank, an oil delivery pipe, an electronic control device, and a pumping device. The atomizing component is located inside the oil storage tank. The oil supply tank is located below or to one side of the oil storage tank. The two ends of the oil delivery pipe are respectively connected to and communicate with the oil storage tank and the oil supply tank. The pumping device includes a piezoelectric ceramic component and an electrical connection component. The piezoelectric ceramic component is located inside the oil supply tank. The two ends of the electrical connection component are electrically connected to the piezoelectric ceramic component and the electronic control device, respectively. Under the control of the electronic control device, the piezoelectric ceramic component vibrates unidirectionally to pump the atomizing matrix in the oil supply tank to the oil storage tank through the oil delivery pipe.
[0042] In the electronic atomization device of this application, when the electronic control device supplies power to the pumping device, the piezoelectric ceramic component undergoes high-frequency unidirectional vibration in response to changes in voltage and / or frequency. This high-frequency unidirectional vibration drives the atomizing matrix in the supply tank into the storage tank. The pumping device can precisely control the supply of the atomizing matrix, ensuring a stable content of the atomizing matrix in the storage tank and preventing problems such as oil leakage from the atomizing component, insufficient atomization, or dry burning of the atomizing component.
[0043] The following will mainly describe the specific structure of electronic atomization devices.
[0044] Please see Figure 1 The electronic atomizing device 100 of this application includes an oil reservoir 110, which stores an atomizing matrix. The atomizing matrix can be e-liquid.
[0045] Please see Figure 1 and Figure 2 The electronic atomizing device 100 of this application includes an atomizing component 120, which is disposed within an oil storage tank 110. The atomizing component 120 is capable of atomizing the atomizing matrix within the oil storage tank 110. The atomizing component 120 can atomize the atomizing matrix by means of ultrasound or heating.
[0046] Please see Figure 1 , Figure 4 and Figure 5 The electronic atomizing device 100 of this application includes a supply tank 130. The supply tank 130 is used to store atomizing matrix to replenish the consumption of atomizing matrix in the storage tank 110. The supply tank 130 is located below the storage tank 110 (e.g., Figure 1 (As shown) or on one side. The oil supply tank 130 and the oil storage tank 110 can be connected to each other or spaced apart (as shown). Figure 1 (As shown).
[0047] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The electronic atomizing device 100 of this application includes an oil delivery pipe 140. The oil delivery pipe 140 is located between the oil storage tank 110 and the oil supply tank 130, and its two ends are respectively connected to and communicate with the oil storage tank 110 and the oil supply tank 130. The oil delivery pipe 140 and the oil storage tank 110, and the oil delivery pipe 140 and the oil supply tank 130 can be connected by sleeve, snap-fit, adhesive or screw, respectively.
[0048] Please see Figure 1 The electronic atomizing device 100 of this application includes an electronic control device 150, which is electrically connected to an atomizing component 120. The atomizing component 120 atomizes the atomizing matrix under the control of the electronic control device 150.
[0049] Please see Figures 1 to 5The electronic atomizing device 100 of this application includes a pumping device. The pumping device includes a piezoelectric ceramic component 160 and an electrical connection component 170. The piezoelectric ceramic component 160 is disposed within the oil supply chamber 130. The two ends of the electrical connection component 170 are electrically connected to the piezoelectric ceramic component 160 and an electronic control device 150, respectively. Under the control of the electronic control device 150, the piezoelectric ceramic component 160 vibrates unidirectionally to pump the atomizing matrix in the oil supply chamber 130 to the oil storage chamber 110 via the oil delivery pipe 140. The unidirectional vibration is a high-frequency unidirectional vibration.
[0050] The pump device can be manually activated. In one embodiment, a control button (not shown) may be provided on the housing of the electronic atomizing device 100. The control button is electrically connected to the electronic control device 150, and the user can operate the control button to activate the pump device before inhalation. The activation of the pump device can also be automatically controlled. In another embodiment, the electronic control device 150 activates the pump device simultaneously with activating the atomizing component 120.
[0051] Please see Figure 1 , Figure 4 and Figure 5 The oil supply chamber 130 has an interconnected oil supply chamber 131 and an oil replenishment chamber 132 inside. The oil supply chamber 131 is connected to the oil supply pipe 140. The piezoelectric ceramic component 160 is located between the oil supply chamber 131 and the oil replenishment chamber 132. The piezoelectric ceramic component 160 has a liquid passage hole 161. The oil supply chamber 131 and the oil replenishment chamber 132 are connected through the liquid passage hole 161.
[0052] When the electronic control device 150 supplies power to the pumping device, the piezoelectric ceramic component 160 will undergo high-frequency unidirectional vibration with changes in voltage and frequency. The high-frequency unidirectional vibration of the piezoelectric ceramic component 160 causes changes in the pressure inside the oil supply chamber 130, resulting in an imbalance of pressure on both sides of the piezoelectric ceramic component 160 (i.e., the oil supply chamber 131 and the oil replenishment chamber 132). The pressure imbalance drives the atomized matrix inside the oil supply chamber 130 to flow into the oil storage chamber 110.
[0053] Specifically, the piezoelectric ceramic component 160 has a deformed state and a non-deformed state. See also... Figure 4 In the deformed state, the piezoelectric ceramic component 160 bulges towards the oil supply chamber 131, and the liquid passage 161 is closed due to the deformation of the piezoelectric ceramic component 160, allowing the atomizing matrix in the oil supply chamber 131 to flow towards the oil storage tank 110. (See also...) Figure 5 In the non-deformed state, the piezoelectric ceramic component 160 is reset, and the liquid passage 161 is opened due to the disappearance of the deformation of the piezoelectric ceramic component 160, so that the atomized matrix in the oil replenishment chamber 132 flows to the oil supply chamber 131.
[0054] Please see Figures 1 to 5The piezoelectric ceramic assembly 160 includes a piezoelectric ceramic sheet 162 and a diaphragm 163 that are connected sideways. The size of the piezoelectric ceramic sheet 162 is smaller than that of the diaphragm 163. The peripheral wall of the diaphragm 163 is connected to the oil supply chamber 130 to divide the inner cavity of the oil supply chamber 130 into an oil supply chamber 131 and an oil replenishment chamber 132. A liquid passage 161 is formed in the diaphragm 163. The peripheral wall of the diaphragm 163 is slidably connected to the wall of the oil supply chamber 130, thereby allowing the diaphragm 163 to deform.
[0055] Please see Figure 2 and Figure 3 The liquid passage 161 is a strip-shaped notch, with one end extending through the edge of the membrane 163 and the other end close to the center of the membrane 163. Thus, when the membrane 163 bulges, the liquid passage 161 can close. The shape of the liquid passage 161 can be straight, which ensures a good sealing effect when the membrane 163 bulges.
[0056] Please see Figure 2 and Figure 3 The number of liquid passage holes 161 is 3 to 6, and the 3 to 6 liquid passage holes 161 are arranged in a centrally symmetrical manner with the center of the diaphragm 163 as the center. Therefore, in the non-deformation state, the atomizing matrix of the oil replenishment chamber 132 flows to the oil supply chamber 131 more effectively.
[0057] Please see Figure 2 and Figure 3 Both the piezoelectric ceramic sheet 162 and the diaphragm 163 are circular, with the center of the piezoelectric ceramic sheet 162 coinciding with the center of the diaphragm 163. Therefore, the piezoelectric ceramic component 160 exhibits good deformation performance, resulting in better pumping of the atomized matrix flow.
[0058] Please refer to the following: Figure 2 and Figure 3 The oil supply chamber 130 includes a first housing 135 and a second housing 136. The second housing 136 is fitted inside the first housing 135 and is generally cylindrical in shape. A piezoelectric ceramic component 160 is disposed inside the second housing 136 and perpendicular to the axial direction of the second housing 136. A diaphragm 163 is connected to the second housing 136. Thus, the shape of the oil supply chamber 130 can be adapted to the shapes of other components (such as the housing of the electronic atomizing device 100 or the electronic control device 150) and the shape of the piezoelectric ceramic component 160, thereby facilitating the installation and function of the pumping device.
[0059] Please refer to the following: Figure 1 , Figure 4 and Figure 5The deformation direction of the piezoelectric ceramic component 160 is parallel to the horizontal direction. Therefore, the deformation direction of the piezoelectric ceramic component 160 is parallel to the flow direction of the atomizing matrix, and the piezoelectric ceramic component 160 is not subjected to downward pressure from the atomizing matrix, resulting in a better pumping effect on the atomizing matrix.
[0060] Please refer to the following: Figure 2 and Figure 3 The oil supply tank 130 has two connection holes 133 on the side facing the electrical connection assembly 170. The electrical connection assembly 170 includes two electrode pins 171, which are respectively inserted through the two connection holes 133. The two ends of the two electrode pins 171 are electrically connected to the piezoelectric ceramic assembly 160 and the electronic control device 150. Thus, the piezoelectric ceramic assembly 160, the electrical connection assembly 170, and the electronic control device 150 can be electrically connected in sequence, and the connection effect is relatively good.
[0061] Please see Figure 3 The walls of the two connecting holes 133 extend toward the piezoelectric ceramic assembly 160 to form two connecting cylinders 134. Two electrode pins 171 are installed in the two connecting cylinders 134 one-to-one. The ends of the two connecting cylinders 134 closest to the piezoelectric ceramic assembly 160 are connected to the piezoelectric ceramic assembly 160. As a result, the installation of the piezoelectric ceramic assembly 160 and the electrical connection assembly 170 in the oil supply tank 130 is more secure.
[0062] Please see Figure 1 The electronic atomizing device 100 of this application includes a gas delivery channel formed between the oil storage chamber 110 and the oil supply chamber 130, connecting the oil storage chamber 110 and the oil supply chamber 130. Therefore, during the operation of the atomizing component 120, the oil storage chamber 110 can be depressurized in a timely manner, preventing leakage of the atomizing matrix; the gas flow to the oil supply chamber 130 increases the air pressure within the oil supply chamber 130, achieving pressure balance between the oil storage chamber 110 and the oil supply chamber 130, resulting in a better oil filling effect from the oil supply chamber 130 to the oil storage chamber 110.
[0063] Please refer to the following: Figure 1 , Figure 4 and Figure 5The oil storage tank 110 has an exhaust port, and the top of the oil supply tank 130 has an air inlet 137. The electronic atomizing device 100 includes an air guide pipe 180 and a buffer chamber 190. The air guide pipe 180 is inserted into the exhaust port, and one end of the air guide pipe 180 is located on the top of the oil storage tank 110. The buffer chamber 190 connects the air guide pipe 180 and the air inlet 137. The air delivery channel is formed by the air guide pipe 180 and the buffer chamber 190. The buffer chamber 190 can buffer the flow of gas, reducing the interference of gas inflow on the vibration of the piezoelectric ceramic component 160. The oil supply pipe 140 can be located inside the buffer chamber 190, which provides protection for the oil supply pipe 140, and at the same time, the structure of the electronic atomizing device 100 is more compact.
