Description

Technical Field

[0001] The present invention relates to the technical field of atomization products, in particular to an atomizer. Background Art

[0002] Existing atomizers typically spray tap water directly into a mist through an atomizer. However, tap water often contains various impurities. If the tap water is directly atomized without treatment, the resulting mist may contain harmful impurities, which can be harmful to the human body and affect the user's health.

[0003] In addition, the mist generated by the atomizer is transmitted to the outside through the mist guide tube, which is usually fixed inside the water tank of the atomizer. When the water tank is deep, the required length of the mist guide tube will also be relatively long, which will reduce the efficiency of mist output. At the same time, the mist in the mist guide tube completely relies on its own buoyancy to be transmitted outward, and the mist output efficiency is low. Summary of the Invention

The atomizing assembly heats and disinfects the water before atomizing it. The resulting mist floats upward along the mist guide tube and is finally ejected to the outside through the mist outlet. As the atomizing assembly atomizes the water, the amount of water gradually decreases, and the buoyancy shield and the atomizing assembly gradually descend with the water level. Because the mist guide tube is retractable, the length of the mist guide tube gradually increases as the buoyancy shield descends, thereby descending along with the buoyancy shield. The mist guide tube primarily serves as a mist guide, and the mist generated by the atomizing assembly is transmitted to the outside through the mist guide tube. When there is a lot of water in the water tank, the length of the mist guide tube is short, resulting in higher mist emission efficiency. As the water level descends, the length of the mist guide tube gradually increases. By making the mist guide tube retractable, mist emission efficiency can be improved. At the same time, the atomizing assembly heats and disinfects the water before atomizing it, which is beneficial to the health of the user.

[0053] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0056] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0057] like Figures 1 to 3 As shown, the atomizer according to an embodiment of the present invention includes a water tank 100, a cover body 200, a retractable mist guide tube 300, a buoyancy cover 400 and an atomization assembly 500; wherein, the upper end of the water tank 100 is open, the cover body 200 is covered at the opening of the water tank 100, and the cover body 200 is provided with a mist outlet 210; the mist guide tube 300 is provided at the lower end of the cover body 200, and the upper end of the mist guide tube 300 is connected with the mist outlet 210; the buoyancy cover 400 is provided with a first central through hole 410, the lower end of the mist guide tube 300 is located at the upper end inside the first central through hole 410, and the atomization assembly 500 is provided at the lower end inside the first central through hole 410; wherein, the atomization assembly 500 is used to heat the water in the water tank 100 and then atomize it, and the mist generated after atomization is transmitted from the mist outlet 210 to the outside through the mist guide tube 300.

[0058] According to the atomizer of an embodiment of the present invention, in actual application, an appropriate amount of water is first added to the inside of the water tank 100, and then the cover body 200 is covered on the water tank 100. At this time, the buoyancy cover 400 floats on the water surface inside the water tank 100, and the atomization component 500 heats and disinfects the water before atomizing it. The mist generated after atomization floats upward along the mist guide pipe 300, and finally is sprayed to the outside through the mist outlet 210. As the atomizing assembly 500 atomizes the water, the water content will gradually decrease, and the buoyancy cover 400 and the atomizing assembly 500 will gradually descend with the water level. Since the mist guide tube 300 is retractable, the length of the mist guide tube 300 will gradually increase during the descent of the buoyancy cover 400, thereby descending together with the buoyancy cover 400. The mist guide tube 300 mainly plays the role of guiding the mist, and the mist generated by the atomizing assembly 500 will be transmitted to the outside world along the mist guide tube 300. When there is more water in the water tank 100, the length of the mist guide tube 300 is shorter and the mist output efficiency is higher. As the water level drops, the length of the mist guide tube 300 will gradually increase. By setting the mist guide tube 300 to be retractable, the mist output efficiency can be improved. At the same time, the atomizing assembly 500 first heats and disinfects the water before atomizing it, which is beneficial to the health of the user. It can be seen that the atomizer according to the embodiment of the present invention can not only improve the mist output efficiency, but also improve the quality of the mist and protect the health of the user.

[0059] like Figures 4 to 9As shown, in some embodiments of the present invention, the atomizer assembly 500 includes a base 510, a circuit board 520, an atomizer sheet 530, a first cover 540, a heating element 550 and a first heat-insulating cover 560; a first water inlet 511 is provided at the bottom of the base 510, and the upper end of the base 510 is open; the circuit board 520 is arranged inside the base 510, and a preheating chamber 512 is formed between the bottom of the circuit board 520 and the bottom of the base 510; the atomizer sheet 530 is arranged on the circuit board 520; the first cover 540 is covered at the upper end of the base 510, and the first cover 540 is provided with a buoyancy chamber 541 opening toward the base, and a first chamber 542 opening away from the base, and the first chamber 54 2 is provided with a first through hole 543 for the atomizing sheet 530 to pass through; the heating element 550 is electrically connected to the circuit board 520, and the bottom of the first chamber 542 is provided with a second through hole 544 for the heating element 550 to pass through; the first heat-insulating cover 560 is detachably arranged in the first chamber 542, and the interior of the first heat-insulating cover 560 forms a heating chamber 561, the atomizing sheet 530 is located outside the first heat-insulating cover 560, and the side wall of the first heat-insulating cover 560 facing the atomizing sheet 530 is provided with a third through hole 562; the bottom of the first chamber 542 is provided with a second water inlet 545 which is respectively connected to the interior of the preheating chamber 512 and the heating chamber 561; the upper end of the heating element 550 is located in the heating chamber 561.

[0060] Specifically, if Figure 8 As shown, in this example, two symmetrical buoyancy chambers 541 are provided on the side of the first cover 540 facing the base 510. The two buoyancy chambers 541 form a buoyancy space to facilitate the atomization assembly 500 to float on the water surface; in order to waterproof the circuit board 520, the bottom of the circuit board 520 can be glued. When the atomizer assembly 500 is placed in the water tank 100, the water in the water tank 100 can enter the preheating chamber 512 through the first water inlet 511 of the base 510. Since the first heat-insulating cover 560 covers the heating element 550 and the second water inlet 545, the water in the preheating chamber 512 can enter the heating chamber 561 through the second water inlet 545. After being heated by the heating element 550, the water flows from the third through hole 562 to the atomizer 530. The atomizer 530, driven by the circuit board 520, atomizes the water. The mist flows through the first cover 540 to the mist guide 300 above and is finally ejected from the mist outlet 210. The heat generated by the circuit board 520 during operation can be dissipated through the glue filling at the bottom, and this heat can preheat the water in the preheating chamber 512, thereby shortening the heating time of the heating element 550 for the water, improving the heating efficiency and atomization efficiency, and reducing the heating power consumption.

[0061] like Figure 12As shown, in some embodiments of the present invention, a waterproof air pressure balance valve 580 is provided on the top of the buoyancy chamber 541; the two buoyancy chambers 541 are interconnected to form the buoyancy space of the atomizer assembly 500, so that the atomizer assembly 500 floats on the water surface. By adding a waterproof air pressure balance valve 580 on the top of the buoyancy chamber 541, the air inside the buoyancy chamber 541 can circulate, so that the internal air pressure is balanced with the external pressure, preventing the pressure change caused by the change of the internal water temperature, causing the buoyancy chamber 541 to absorb external water, thereby affecting the atomizer assembly 500 floating on the water surface. According to the atomizer assembly 500 of the embodiment of the present invention, a preheating chamber 512 is formed between the base 510 and the circuit board 520, so that the heat generated by the circuit board 520 during operation can preheat the water in the preheating chamber 512, thereby shortening the heating time of the water by the heating element 550, improving the heating efficiency and atomization efficiency, and reducing the heating power consumption; at the same time, since the first heat-insulating cover 560 is arranged in the first chamber 542 and forms a heating chamber 561, the water in the preheating chamber 512 passes through the second water inlet 545 and first enters the heating chamber 561, and is heated by the heating element 550 before flowing to the atomizer plate 530 through the third through hole 562; the heating chamber 561 can not only heat and keep the water warm, but also reduce the working range of the atomizer plate 530, so that only the required part of the water exists in the working area of the atomizer plate 530, and the rest of the water remains in the heating chamber 561, thereby improving the atomization efficiency of the atomizer plate 530.

[0062] like Figure 4 、 Figure 6 and Figure 11 As shown, in some embodiments of the present invention, the atomization assembly 500 also includes a second thermal insulation cover 570, which is detachably arranged in the first chamber 542 and is arranged opposite to the first thermal insulation cover 560. The atomization sheet 530 is located outside the second thermal insulation cover 570, and the second thermal insulation cover 570 is provided with a fourth through hole 572 on the side wall facing the atomization sheet 530; a thermal insulation cavity 571 is formed inside the second thermal insulation cover 570. On the one hand, the second heat preservation cover 570 and the first heat preservation cover 560 are symmetrically arranged on both sides of the first chamber 542, so as to maintain the balance of the entire atomization assembly 500; on the other hand, the moisture heated by the heating element 550 in the heating chamber 561 can enter the heat preservation chamber 571 through the third through hole 562 and the fourth through hole 572. The heat preservation chamber 571 has an insulation effect on the moisture and further reduces the working range of the atomization piece 530, so that only the required part of the moisture exists in the working area of the atomization piece 530, and the rest of the moisture remains in the heating chamber 561 and the heat preservation chamber 571 for insulation, thereby improving the atomization efficiency of the atomization piece 530.

[0063] By setting a first heat-insulating cover 560 and a second heat-insulating cover 570 in the first chamber 542, the first chamber 542 is divided into three sections, namely a heating zone, a working zone and a heat-insulating zone, wherein the interior of the first heat-insulating cover 560 serves as a heating zone, the area where the atomizing sheet 530 is located serves as a working zone, and the interior of the second heat-insulating cover 570 serves as a heat-insulating zone. The water in the water tank 100 enters the preheating chamber 512 through the first water inlet 511 of the base 510 for preheating, and then enters the heating chamber 561 through the second water inlet 545 for heating. Since the space in the heating zone is small and the water has been preheated, the heating efficiency is fast, and the water can be quickly heated to a higher temperature to achieve the effect of disinfection and sterilization. At the same time, since the atomizing plate 530 has a lower working efficiency at a higher temperature, it is necessary to properly cool the water before atomization. Since the working area is large, the temperature of the water in the heating area will drop rapidly as it flows through the third through-hole 562 to the working area, reaching a temperature suitable for the operation of the atomizing plate 530, thereby ensuring the atomization efficiency of the atomizing plate 530. In addition, to prevent the water temperature from dropping too quickly and the excessive amount of water inside the working area from affecting the atomization efficiency of the atomizing plate 530, a second heat-insulating cover 570 is formed to form a heat-insulating area. On the one hand, this keeps the water warm, and on the other hand, it reduces the moisture in the working area, thereby improving the working efficiency of the atomizing plate 530.

[0064] like Figure 10 and Figure 11 As shown, in some embodiments of the present invention, a first air vent 563 is provided at the top of the heating chamber 561, and a second air vent 573 is provided at the top of the heat-insulating chamber 571; a first gripping portion 564 is provided at the upper end of the first heat-insulating cover 560, and a second gripping portion 574 is provided at the upper end of the second heat-insulating cover 570. During the evaporation process of water in the heating chamber 561 and the heat-insulating chamber 571, steam can flow out through the first air vent 563 and the second air vent 573, thereby preventing the internal air pressure of the heating chamber 561 and the heat-insulating chamber 571 from being too high; and the provision of the first gripping portion 564 and the second gripping portion 574 makes the installation and removal of the first heat-insulating cover 560 and the second heat-insulating cover 570 more convenient.

[0065] In some embodiments of the present invention, an ultraviolet germicidal lamp, a water level detection element 548, and a water temperature detection element are provided in the first chamber 542. The ultraviolet germicidal lamp, the water level detection element 548, and the water temperature detection element are electrically connected to the circuit board 520, and the ultraviolet germicidal lamp, the water level detection element 548, and the water temperature detection element are all located in the heating chamber 561. Figure 9As shown, a first mounting hole 547 and a second mounting hole 549 are provided at the bottom of the first chamber 542. The first mounting hole 547 is used to install an ultraviolet germicidal lamp, and the second mounting hole 549 is used to install a water temperature detection element. The ultraviolet germicidal lamp disinfects the water, further improving the water quality. The water level detection element 548 is used to detect whether the water level has reached a preset position and send a detection signal to the circuit board 520. When the water level reaches the preset position, the circuit board 520 controls the heating element 550 to heat up. When it is detected that there is less water or no water, the heating element 550 stops working to prevent dry burning. The water temperature detection element is used to detect the water temperature inside the heating chamber 561, so that the circuit board 520 controls the heating state of the heating element 550 according to the water temperature.

[0066] like Figure 6 As shown, in some embodiments of the present invention, the heating element 550 includes a heating rod 551 and a heat insulating pad 552 disposed around the bottom of the heating rod 551. The heating rod 551 is used to heat and sterilize the water, while the heat insulating pad 552 is used to prevent the heat of the heating rod 551 from being directly transferred to the surrounding plastic parts. The heat insulating pad 552 can be made of silicone.

[0067] like Figures 4 to 6 As shown, in some embodiments of the present invention, a first wire-holding portion 546 is provided on the outer sidewall of the first housing 540, and a through-slot 513 is provided on the sidewall of the base 510 at a position corresponding to the first wire-holding portion 546. The first wire-holding portion 546 passes through the through-slot 513 and is located outside the base 510; the wires associated with the circuit board 520 can be arranged and secured by the first wire-holding portion 546.

[0068] like Figure 12 and Figure 13As shown, in some embodiments of the present invention, the cover body 200 includes a bottom cover 220, a fan 230, a second cover body 240 and a top cover 250; the bottom cover 220 is arranged at the opening of the water tank 100, the bottom cover 220 is arranged around the outer side of the upper end of the mist guide pipe 300, and a second central through hole 221 is opened to match the upper end of the mist guide pipe 300; the fan 230 is arranged at the upper end of the bottom cover 220, and the side wall of the mist guide pipe 300 is opened with an air inlet 340. The air outlet 231 of the fan 230 faces the lower side of the bottom cover 220 and the outer side of the mist guide pipe 300; the second cover body 240 is covered on the upper end of the bottom cover 220, and a mist guide column 241 is provided inside the second cover body 240. The lower end of the mist guide column 241 is connected to the second central through hole 221, and a ventilation hole 242 is opened on the side wall of the second cover body 240; the top cover 250 is covered on the upper end of the mist guide column 241, and a mist outlet 210 is opened on the top cover 250. After the mist generated by the atomizing assembly 500 rises along the mist guide tube 300, it flows into the mist guide column 241 from the second central through hole 221 and is finally ejected outward from the mist outlet 210. In order to accelerate the rising speed of the mist, the air blown by the fan 230 blows along the air outlet 231 toward the lower side of the bottom cover 220 and enters the interior of the mist guide tube 300 along the air inlet 340 of the mist guide tube 300, pressurizing the interior of the mist guide tube 300 and accelerating the discharge of the mist, thereby further improving the efficiency of mist discharge. The vent 242 provided on the side wall of the second cover 240 is used to allow outside air to enter the interior of the second cover 240, so that the fan 230 can operate normally. At the same time, the chamber formed between the second cover 240, the mist guide column 241 and the bottom cover 220 can separate the mist from the fan 230, preventing the corresponding circuit structure from coming into contact with the mist and malfunctioning. The mist outlet 210 can collect the mist and then release it to the outside.

[0069] In some embodiments of the present invention, the mist guide pipe 300 includes a plurality of tube bodies sequentially arranged from top to bottom, and the lower end of each tube body is provided with an air inlet 340. Figure 3As shown, in this example, the mist guide tube 300 includes a first tube body 310, a second tube body 320 and a third tube body 330 from top to bottom (it can be understood that the specific number of tube bodies can be adjusted according to actual needs and is not limited to three); wherein the first tube body 310 is fixed to the lower end of the bottom cover 220, and the bottom cover 220 is provided with a second central through hole 221 connected to the first tube body 310; the first tube body 310 is sleeved on the outside of the second tube body 320, and the second tube body 320 can slide up and down inside the first tube body 310; similarly, the second tube body 320 is sleeved on the outside of the third tube body 330, and the third tube body 330 can slide up and down inside the second tube body 320; the lower end of the third tube body 330 is located at the upper end inside the first central through hole 410 of the buoyancy cover 400, so that as the buoyancy cover 400 rises or falls along the water surface, the length of the entire mist guide tube 300 is changed. When the water level is high and the mist guide tube 300 is short, the misting efficiency is high. As the water level decreases and the water level drops, the length of the mist guide tube 300 gradually increases. Furthermore, an air inlet 340 is provided at the lower end of each tube. Air from the fan 230 enters the mist guide tube 300 through each air inlet 340, thereby accelerating the discharge of mist and improving misting efficiency.

[0070] like Figure 2 As shown, in some embodiments of the present invention, a first annular protrusion 420 is provided at the upper end of the buoyancy cover 400, located outside the first central through hole 410. A second annular protrusion 430 is provided at the upper edge of the buoyancy cover 400, and the second annular protrusion 430 is provided with a second line-gripping portion 440. The area enclosed by the first annular protrusion 120 and the mist guide tube 300 forms a hot water recovery zone, and the second annular protrusion 130 and the first annular protrusion 120 form a splash zone. When water heated by the atomizer assembly 500 overflows into the upper end of the buoyancy cover 400, the first annular protrusion 120 prevents the hot water from continuing to flow out, and instead promotes the hot water to flow back into the first central through hole 410 for atomization by the atomizer assembly 500. The splash zone is used to prevent water from splashing out during the operation of the atomizer assembly 500. The wires involved in the atomizer assembly 500 can be connected to the control circuit inside the second cover body 240 after passing through the first wire clamping part 546 and the second wire clamping part 440. The control circuit inside the second cover body 240 is used to control the working state of the entire atomizer; at the same time, a wire port 243 is provided on the side wall of the second cover body 240, and the power cord can be used to power the internal circuit components through the wire port 243.

[0071] like Figure 3 and Figure 15As shown, the atomizer according to the embodiment of the present invention further includes a recovery cover 600, which is provided at the upper end of the atomizing assembly 500 and is located inside the lower end of the mist guide tube 300; the recovery cover 600 includes two inner and outer circles of staggered sheets. The recovery cover 600 forms a gap between the inner and outer circles of staggered sheets, so that the mist generated by the atomizing assembly 500 can pass through the recovery cover 600 and enter the mist guide tube 300, thereby blowing the mist out. The water column and water droplets generated during the working process of the atomizing assembly 500 will hit the staggered sheets and flow back into the first chamber 542 along the inner wall of the staggered sheets, thereby preventing the water column bounced by the atomizing sheet 530 from being too high and the water droplets from flying around, and preventing excessive heat loss under the action of the wind.
