The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).
[0044] The atomizer and atomization equipment provided by the present application provide a liquid replenishment interface between the atomization bin and the liquid replenishment bin, and adopt a liquid replenishment component with a simple structure and convenient operation. When a liquid replenishment operation is required, it is only necessary to press the pressing piece of the liquid replenishment component, and the air pressure in the liquid replenishment bin can be used to squeeze the atomized liquid and enter the atomization bin through the liquid replenishment interface, so that the atomization core can be heated and atomized, and the amount of liquid replenishment is easy to control. When liquid replenishment is not required, the liquid replenishment interface can also maintain a pressure balance between the atomization bin and the liquid replenishment bin to prevent leakage.
[0045] Some embodiments of the atomizer and atomization device provided by the present application are described below in conjunction with the accompanying drawings.
[0046] In an embodiment of the first aspect of the present application, a nebulizer 100 is provided, such as Figure 1 , Figure 2 and Figure 3 As shown, the atomizer 100 includes a housing 1, an atomizing core 2 and a liquid replenishing assembly 3. The housing 1 has an atomizing bin 121 and a liquid replenishing bin 15. The atomizing bin 121 can contain atomizing liquid, and the atomizing core 2 is arranged in the atomizing bin 121, which is used to heat the atomizing liquid so that the atomizing liquid is atomized to generate an aerosol; the housing 1 also has a nozzle structure 111 and an air inlet duct 122, the nozzle structure 111 is connected to one end of the atomizing core 2, and the air inlet duct 122 is connected to the other end of the atomizing core 2, so that external gas can enter the atomizing core 2 through the air inlet duct 122, and mix with the aerosol generated by the atomizing liquid, and then flow out from the nozzle structure 111. The liquid replenishing tank 15 is used to store the atomized liquid, and a liquid replenishing interface 16 is provided at the connection between the liquid replenishing tank 15 and the atomizing tank 121. Under the action of pressure, the liquid replenishing interface 16 can make the liquid replenishing tank 15 connected with the atomizing tank 121, and under the natural state, the liquid replenishing interface 16 can maintain the pressure balance between the atomizing tank 121 and the liquid replenishing tank 15; the liquid replenishing component 3 is arranged corresponding to the liquid replenishing tank 15, including a liquid replenishing support member 31 and a pressing member 32, the liquid replenishing support member 31 is located in the liquid replenishing tank 15, the pressing member 32 is penetrated in the tank wall of the liquid replenishing tank 15, and one end is movably connected to the liquid replenishing support member 31, and the other end extends out of the liquid replenishing tank 15, the pressing member 32 can move toward the liquid replenishing tank 15 when pressed, so as to increase the air pressure in the liquid replenishing tank 15, and make the atomized liquid pass through the liquid replenishing interface 16 into the atomizing tank 121 under the action of the air pressure, so as to realize the liquid replenishing operation.
[0047] It is understandable that most existing atomization devices use an injection structure with an oil channel. The oil channel is connected or closed to the liquid filling port by the movement of the injection structure between different positions, thereby performing a liquid filling operation. However, the oil channel of the injection structure is usually more complicated and requires high matching accuracy, while the injection flow rate is not easy to control, making it difficult to meet the user's usage requirements.
[0048] The atomizer 100 in this embodiment, through the improvement and optimization of the structure, makes the refilling operation easy to operate through the cooperation of the refilling component 3 and the refilling interface 16, which is similar to the operation of an air pump. The refilling amount can be accurately controlled, and when refilling is not needed, the pressure on both sides of the atomization chamber 121 and the refilling chamber 15 can be balanced through the refilling interface 16, which can effectively prevent leakage and the phenomenon of burnt or scorched smell caused by poor refilling, which is beneficial to improving the user experience, and has a simple structure, which is beneficial to reducing costs.
[0049] It should be noted that in actual applications, the flow area of the liquid replenishment interface 16 can be set as needed, for example, a smaller flow area, so that the liquid replenishment interface 16 is in a state of pressure balance at both ends under a natural state, thereby preventing the atomized liquid in the liquid replenishment tank 15 from leaking to the side of the atomization tank 121.
[0050] In a further embodiment of the present application, Figure 3 , Figure 4 and Figure 5 As shown, a first gas storage cavity 311 is formed in the liquid replenishment support 31, which can accommodate gas; the liquid replenishment support 31 is connected and fixed to the wall of the liquid replenishment tank 15, and a vent hole 312 is provided on the liquid replenishment support 31, so that the first gas storage cavity 311 is connected with the internal space of the atomization tank 121 through the vent hole 312. Correspondingly, one end of the pressing member 32 extends into the first gas storage cavity 311 and is sealed with the side wall of the first gas storage cavity 311, and the other end of the pressing member 32 extends out of the atomization tank 121 for the user to perform a pressing operation. When the pressing member 32 moves into the first gas storage chamber 311 in the pressed state, the space for accommodating gas in the first gas storage chamber 311 is reduced, and the gas stored in the first gas storage chamber 311 passes through the vent hole 312 into the space for accommodating atomized liquid in the liquid replenishing chamber 15, thereby increasing the air pressure in the liquid replenishing chamber 15, and the atomized liquid passes through the liquid replenishing interface 16 under the action of the air pressure and enters the atomizing chamber 121. Among them, since the flow rate of the liquid replenishing interface 16 is linearly related to the air pressure in the liquid storage chamber, and the air pressure is linearly related to the movement stroke of the pressing member 32, the flow rate of the liquid replenishing interface 16 can be controlled by controlling the pressing force of the pressing member 32, thereby realizing accurate control of the amount of liquid replenishment.
[0051] Furthermore, in a specific implementation, Figure 3 , Figure 4 and Figure 5In the example, a pressing port 113 is provided on the housing 1, which is specifically located at the side of the nozzle structure 111 and at a position corresponding to the liquid replenishing tank 15; the end of the first air storage cavity 311 away from the vent 312 is connected to the pressing port 113, and the end of the pressing member 32 away from the vent 312 extends outward through the pressing port 113, so that the space where the pressing member 32 is located in the first air storage cavity 311 is divided into two mutually isolated parts. The liquid replenishing support member 31 is detachably connected to the housing 1 for easy assembly; the liquid replenishing support member 31 is sealed with the side wall of the liquid replenishing tank 15 to ensure air tightness.
[0052] Furthermore, in a specific example, Figure 3 , Figure 4 and Figure 5 In the example of the infusion assembly 3, the outer side of the pressing member 32 facing the vent hole 312 has a boss structure 321, the size of the boss structure 321 is adapted to the first air storage cavity 311, and the outer surface of the boss structure 321 is sleeved with a first sealing member 322, the first sealing member 322 abuts against the inner wall of the first air storage cavity 311 to seal the gap between the boss structure 321 and the inner wall of the first air storage cavity 311, thereby ensuring air tightness; at the same time, by providing the boss structure 321, it can play a limiting role when the pressing member 32 is located near the pressing port 113, preventing the pressing member 32 from being pulled out of the pressing port 113 and detaching. Specifically, the first sealing member 322 can be a sealing ring.
[0053] Furthermore, in a specific example, Figure 3 , Figure 4 and Figure 5 In the example in FIG. 1 , the pressing member 32 is a hollow structure, and has a second gas storage cavity 323 inside thereof for storing gas; the end of the second gas storage cavity 323 facing the vent hole 312 is a through structure, which enables gas to enter the liquid replenishing tank 15 through the vent hole 312. By providing the second gas storage cavity 323, the gas storage capacity in the liquid replenishing assembly 3 can be further increased, and the gas pressure during the liquid replenishing operation can be increased.
[0054] Furthermore, in a specific example, an elastic reset member 33 is also provided in the first air storage cavity 311. The elastic reset member 33 is provided between the pressing member 32 and the vent hole 312, and one end of the elastic reset member 33 abuts against the pressing member 32, and the other end abuts against the cavity wall of the first air storage cavity 311 at one end where the vent hole 312 is provided. When the pressing member 32 is pressed and moves toward the vent hole 312, the elastic reset member 33 is compressed and generates potential energy to restore to its original state. When the external force acting on the pressing member 32 is removed, the potential energy of the elastic reset member 33 is converted into kinetic energy, so that the pressing member 32 moves in a direction away from the vent hole 312 under the action of the elastic force, thereby realizing the reset function. Among them, the elastic reset member 33 can be used as follows Figure 3The spring shown in the figure can of course also be other forms of elastic members.
[0055] In a further embodiment of the present application, Figure 3 , Figure 6 and Figure 7 In the example, the liquid replenishment interface 16 of the atomizer 100 includes an interface groove 161 and a liquid guide column 162. The interface groove 161 is specifically located on the outer wall of the atomization bin 121, and the open end of the interface groove 161 is connected to the liquid replenishment bin 15, and the bottom wall of the interface groove 161 is provided with a liquid replenishment hole 1611; the liquid guide column 162 is inserted into the interface groove 161, and abuts against the inner wall of the interface groove 161 in the circumferential direction to block part of the space of the interface groove 161; wherein, a plurality of liquid guide grooves 1621 are provided on the outer wall of the liquid guide column 162, one end of the liquid guide groove 1621 is connected to the liquid replenishment bin 15, and the other end is connected to the liquid replenishment hole 1611, and the atomized liquid in the liquid replenishment bin 15 can enter the interface groove 161 through the liquid guide groove 1621 under pressure, and enter the atomization bin 121 through the liquid replenishment hole 1611 to achieve liquid replenishment.
[0056] Specifically, Figure 8 and Fig. 9 As shown, the liquid guiding grooves 1621 are all small-sized micro-groove structures. When the outer wall of the liquid guiding column 162 is in contact with the interface groove 161, the flow area of each liquid guiding groove 1621 is relatively small relative to the interface groove 161. Figure 6 and Figure 7 As shown, the size of the liquid replenishment hole 1611 can be set to match the liquid guide groove 1621, so that the flow area of the liquid replenishment hole 1611 is matched with the liquid guide groove 1621, to prevent the leakage of the atomized liquid due to a large flow area. In a natural state, the liquid guide groove 1621 with a micro-groove structure can generate resistance to the atomized liquid, so that the pressure on both sides remains stable, and prevents the atomized liquid in the liquid replenishment bin 15 from flowing into the atomization bin 121.
[0057] Furthermore, if Figures 3 to 6 In the example, the outer wall of the liquid-conducting column 162 forms a rigid fit with the interface groove 161 to keep the liquid-conducting column 162 fixed; in the axial direction of the liquid-conducting column 162 (i.e. Figure 8 The diameter of one end of the liquid guide column 162 is larger than the diameter of the other end. After being assembled with the interface groove 161, Figure 3 In the example, the end with a larger diameter is toward the liquid replenishing tank 15, and the end with a smaller diameter is toward the liquid replenishing hole 1611 (i.e., toward the direction away from the liquid replenishing tank 15), so that in the direction along the axial direction of the liquid guide column 162 toward the liquid replenishing hole 1611, the flow area in the interface groove 161 gradually increases, which can play a certain guiding role, so that the atomized liquid can enter the atomization tank 121 more smoothly when passing through.
[0058] Furthermore, if Figure 3 and Figure 7 In the example, a plurality of protruding structures 1612 are arranged on the bottom wall of the interface groove 161, and the protruding structures 1612 extend along the axial direction of the liquid guide column 162, and abut against one end of the liquid guide column 162 facing the atomization bin 121, so that after the assembly of the liquid guide column 162, there is a certain gap between the end of the liquid guide column 162 facing the atomization bin 121 and the bottom wall of the groove of the interface groove 161, which can accommodate a certain amount of atomized liquid. When performing the liquid replenishment operation, the gap can be used to guide the flow and reduce the impact, so that the atomized liquid passes through the liquid replenishment hole 1611 more smoothly; in the natural state, when the liquid replenishment operation is not required, the gap can also use its accommodating capacity to prevent backflow. Specifically, the multiple protruding structures 1612 have the same size in the axial direction, so that they can abut against the end face of the liquid guide column 162 at the same time. Preferably, the multiple liquid guide columns 162 are connected to the inner side wall of the interface groove 161 to facilitate processing and reserve enough space for the liquid replenishment hole 1611.
[0059] Furthermore, in a specific example, Figure 3 and Figure 7 As shown, the bottom wall of the interface groove 161 also has a guide groove 1613, which is concave relative to the bottom wall of the interface groove 161 toward the side close to the atomization bin 121, and the liquid replenishing holes 1611 are located in the guide groove 1613, and there are multiple of them; the multiple liquid replenishing holes 1611 are arranged at intervals in the circumferential direction of the interface groove 161 to increase the liquid replenishing flow rate, and at the same time can more evenly cover different areas on the bottom wall of the interface groove 161. Among them, by setting the guide groove 1613, the atomized liquid can be further provided with a road, guiding the atomized liquid to quickly pass through the liquid replenishing holes 1611, thereby improving the efficiency of the liquid replenishing operation.
[0060] In a further embodiment of the present application, Figures 3 to 5 As shown, a liquid absorption structure 124 is provided in the atomization chamber 121. The liquid absorption structure 124 is attached to the circumferential outer side of the atomization core 2, and can absorb the atomized liquid in the atomization chamber 121, so that the atomized liquid can contact the atomization core 2 through the liquid absorption structure 124, and can be distributed along the circumference of the atomization core 2, so as to increase the heating coverage area and improve the atomization efficiency. Specifically, the liquid absorption structure 124 can be a liquid absorption cotton. The outer side surface of the liquid absorption structure 124 abuts against the side wall of the atomization bin 121 and covers at least part of the liquid replenishment hole 1611. When the atomized liquid in the liquid replenishment bin 15 enters the atomization bin 121 through the liquid replenishment hole 1611, it can be directly adsorbed in the liquid absorption structure 124, and then flow circumferentially toward the atomization core 2, thereby avoiding the replenished atomized liquid from gathering at the bottom of the atomization bin 121. On the one hand, the replenished atomized liquid can be heated and atomized as quickly as possible, and on the other hand, it can also prevent the atomized liquid from gathering at the bottom of the atomization bin 121 and causing leakage.
