Description

Technical Field

[0001] This utility model relates to the field of air improvement equipment, specifically to an atomizing head that increases the amount of mist output. Background Technology

[0002] As people's living standards continue to improve, they participate in more and more activities. However, in many venues, such as hotels, poor air quality can easily lead to fatigue, irritability, and other unpleasant feelings. To create a better environment, people commonly use solid fragrances or spray perfumes in rooms to improve air quality, thereby keeping the air fresh, eliminating odors, and disinfecting. However, the former method often results in the fragrance of the solid fragrance not being fully released, leading to some waste. The latter method is cumbersome to use, and because the sprayed perfume particles are relatively large, their range of movement is small, making this method inefficient. Therefore, a fragrance device that can atomize essential oils has been developed.

[0003] Chinese patent application No. 202411972126.5, published on April 4, 2025, discloses an aroma diffuser, which includes a liquid storage bottle and an atomizing head. The atomizing head includes an atomizing device and a mist outlet. The atomizing device is connected to an air pump and a liquid suction tube, which extends into the liquid storage bottle. The atomizing device is used to mix the liquid in the liquid storage bottle with the air output by the air pump, atomize it, and spray it out of the mist outlet.

[0004] Reference Figure 1 As shown, the droplets flow along the lower wall of the nozzle. Since the cross-sectional dimensions of the nozzle output end are the same as those of the nozzle, the droplets do not change direction as they flow outward from the nozzle. The droplets approach the bottom of the nozzle output end along the lower wall of the nozzle and then are ejected outward. Due to the angle between the lower wall of the nozzle and the vertical line, the coverage area of ​​the droplets directly above the nozzle is small, which reduces the diffusion range of the droplets and decreases the droplet dispersion velocity. At the same time, droplet backflow occurs when the droplets avoid contact with the nozzle, which reduces the amount of mist output from the atomizing head. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an atomizing head that increases the mist output. By sealing the output end of the mist outlet with a nozzle, the atomized droplets are sprayed out from the nozzle. This increases the speed of the droplets as they flow through the nozzle, avoids backflow of droplets at the mist outlet, and increases the mist output of the atomizing head.

[0006] To solve the above-mentioned technical problems, the technical solution used in this utility model is as follows:

[0007] This utility model discloses an atomizing head for increasing mist output, comprising an atomizing head main housing, a top cover, a baffle, an atomizing core holder, and an atomizing core. The top cover is connected to the upper end of the atomizing head main housing. The atomizing head main housing is provided with an atomizing chamber and a mist outlet communicating with the atomizing chamber. The atomizing core holder is inserted into the atomizing head main housing from one side. The atomizing core is connected to the atomizing core holder and located within the atomizing chamber. The atomizing core holder provides airflow to the atomizing core. The atomizing core holder is also provided with a liquid suction tube insertion hole for providing liquid to the atomizing core. An opening communicating with the atomizing chamber is provided on the upper part of the atomizing head main housing. The top cover is installed at the opening. A nozzle is provided at the output end of the mist outlet, and the nozzle blocks the output end of the mist outlet. A spray nozzle is formed on the nozzle.

[0008] Preferably, the nozzle is a semi-closed tube at one end, with the end away from the nozzle inserted into the mist outlet, and the end closer to the nozzle protruding outward relative to the mist outlet. The nozzle is offset relative to the axis of the mist outlet towards the top of the mist outlet.

[0009] Preferably, the nozzle is generally elongated elliptical, with its minor axis extending along the height direction;

[0010] Along the mist outlet direction, the inner wall of the nozzle is inclined inward, or a guide slope is provided on the nozzle and the guide slope is located on the inner side of the nozzle; along the mist outlet direction, the guide slope is inclined inward.

[0011] Preferably, the slope of the guide slope is greater than the slope of the inner wall of the nozzle.

[0012] Preferably, the nozzle is embedded in the output end of the mist outlet.

[0013] Preferably, a receiving cavity is recessed outward inside the output end of the mist outlet, and a first step is formed between the receiving cavity and the inner wall surface of the mist outlet; a second step is convex outward on the outer wall surface of the nozzle, the second step is accommodated in the receiving cavity, and the outer wall of the second step fits against the receiving cavity and abuts against the first step.

[0014] Preferably, the end of the nozzle away from the second step is housed in the mist outlet and fits against the inner wall of the mist outlet.

[0015] Compared with the prior art, the beneficial effects of the atomizing head of this utility model that increases the mist output are mainly reflected in:

[0016] By sealing the output end of the mist outlet with a nozzle, atomized droplets are ejected through the nozzle. This increases the velocity of the droplets as they flow through the nozzle, preventing backflow and increasing the mist output of the atomizing head. The nozzle is offset towards the top of the mist outlet, creating an air passage that slopes upwards between the lower wall of the mist outlet and the nozzle. The droplets flow along this passage and are ejected upwards relative to the nozzle's axis, resulting in a large coverage area directly above the mist outlet. Simultaneously, the offset of the nozzle towards the top increases its horizontal height and the angle between the lower wall of the mist outlet and the nozzle, further reducing the angle between the extended line of the droplet ejection direction and the vertical line, further increasing the coverage area directly above the mist outlet, expanding the droplet diffusion range, and increasing the droplet dispersion velocity.

[0017] By setting an inwardly inclined nozzle inner wall or setting a guide slope, the cross-sectional size of the nozzle gradually narrows along the mist outlet direction, increasing the speed of the liquid passing through the nozzle.

[0018] The slope of the guide ramp is greater than the slope of the inner wall of the nozzle; when the droplet flows through the guide ramp, the angle between the extended line of the droplet ejection direction and the vertical line is further reduced, further increasing the coverage area of ​​the droplet on the area directly above the nozzle.

[0019] By embedding the nozzle at the output end of the mist outlet, the connection between the nozzle and the output end of the mist outlet is reliable. The nozzle is installed and limited by the contact between the first step and the second step; at the same time, the outer wall of the second step fits into the receiving cavity, and the end of the nozzle away from the second step fits into the inner wall of the mist outlet, increasing the contact area between the nozzle and the mist outlet and improving the connection stability between the nozzle and the mist outlet.

[0020] This invention seals the output end of the mist nozzle with a nozzle, allowing the atomized droplets to be ejected from the nozzle. This increases the speed of the droplets as they flow through the nozzle, preventing droplet backflow and increasing the mist output of the atomizing head. Attached Figure Description

[0030] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0031] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0032] like Figure 2-7As shown, an atomizing head for increasing mist output includes a main housing 1, a top cover 2, a baffle 3, an atomizing core holder 4, and an atomizing core 41. The top cover 2 is connected to the upper end of the main housing 1. The main housing 1 has an atomizing chamber 11 and a mist outlet 12 communicating with the atomizing chamber 11. The atomizing core holder 4 is inserted into the main housing 1 from one side. The atomizing core 41 is connected to the atomizing core holder 4 and located in the atomizing chamber 11. Inside, the atomizing core holder 4 provides airflow to the atomizing core 41. The atomizing core holder 4 is also provided with a liquid suction tube insertion hole for providing liquid to the atomizing core 41. The upper part of the atomizing head main housing 1 is provided with an opening 13 communicating with the atomizing chamber 11. The upper cover 2 is installed at the opening 13. The upper cover 2 and the baffle 3 are integrally set. By setting the upper cover 2 and the baffle 3 as an integral unit, the connection strength between the upper cover 2 and the baffle 3 is increased. At the same time, the upper cover 2 is detachable.

[0033] The baffle 3 is located below the upper cover 2 and extends into the atomizing chamber 11. The baffle 3 covers the atomizing core 41. A gap is provided between the baffle 3 and the inner wall of the atomizing head main housing 1. The upper cover 2 is provided with a vent 21. A connecting hole 22 is provided between the upper cover 2 and the baffle 3. The connecting hole 22 communicates with the vent 21. External air can enter the atomizing chamber 11 below the baffle 3 through the vent 21, the connecting hole 22, and the gap between the baffle 3 and the inner wall of the atomizing head main housing 1. The connecting hole 22, which is formed between the upper cover 2 and the baffle 3, is used to replenish air to the atomizing chamber 11. The structure is simple. External air flows into the atomizing chamber 11 through the vent 21, the connecting hole 22, and the gap between the baffle 3 and the inner wall of the atomizing head main housing, increasing the amount of air entering the atomizing chamber 11.

[0034] In a preferred embodiment, the upper cover 2 is detachably installed at the opening 13. Once the upper cover 2 is installed, the upper cover 2 and the baffle 3 can be assembled simultaneously; during disassembly, separating the upper cover 2 allows for the simultaneous removal of the upper cover 2 and the baffle 3; the structure is simple.

[0035] The upper end of the atomizing head main housing 1 has a mounting groove 14 with the opening 13. A fixing hole 141 is provided on the side wall of the mounting groove 14. A protrusion 23 is provided on the outer periphery of the upper cover 2, and the protrusion 23 is inserted into the fixing hole 141. The upper cover 2 is installed by the cooperation of the mounting groove 14 and the upper cover 2; the contact area between the upper cover 2 and the atomizing head main housing 1 is increased by the cooperation of the protrusion 23 and the fixing hole 141, thus improving the stability of the upper cover 2 installed on the atomizing head main housing 1.

[0036] The inner wall of the atomizing head main housing 1 has a notch 111 formed at the position corresponding to the mist outlet 12. The notch 111 connects the mist outlet 12 and the mounting groove 14. When the air ejected from the atomizing core 41 flows towards the mist outlet 12, it will bring the air around the input end of the mist outlet 12 into the mist outlet 12 together. By setting the notch 111 connecting the mist outlet 12 and the mounting groove 14, the notch 111 is connected to the atomizing chamber 11, increasing the amount of air entering the mist outlet. At the same time, the notch 111 increases the opening size of the input end of the mist outlet 12, thus increasing the atomization volume.

[0037] The baffle 3 is an upwardly convex arc shape. The upper cover 2 is integrally connected to the arc top of the baffle 3 through two connecting plates 5. The connecting hole 22 is formed between the upper cover 2, the baffle 3 and the two connecting plates 5.

[0038] The atomizing head main housing 1 has an outwardly protruding circular flange 15 and a connecting post 151 located outside the flange 15 on the outer wall of the side away from the nozzle 12. The atomizing core seat 4 includes a mounting plate 42. A retaining ring 43 is provided on the side of the mounting plate 42 facing the atomizing head main housing 1. The retaining ring 43 is locked on the outer side of the flange 15 and the connecting post 151. The mounting plate 42 is fixedly connected to the connecting post 151 by screws passing through the mounting plate 42.

[0039] The main housing 1 of the atomizing head is provided with a partition 16 that separates the main housing 1 of the atomizing head. The atomizing chamber 11 is formed above the partition 16. The connecting part 17 for connecting with the essential oil bottle 8 is provided below the partition 16. The partition 16 is provided with a through hole 161. The through hole 161 is eccentrically positioned on the partition 16 away from the mist outlet 12. The upper surface of the partition 16 facing the atomizing chamber 11 is inclined, and the side closer to the mist outlet 12 is higher than the side away from the mist outlet 12. The through hole 161 is used to communicate with the essential oil bottle 8. The inclined surface of the partition 16 facing the upper surface of the atomizing chamber 11 guides the droplets that do not enter the mist outlet 12 back to the essential oil bottle 8. Some droplets sprayed by the atomizing core 41 adhere to the inner wall of the atomizing head main housing 1. These droplets fall into the inclined surface under the action of gravity and then flow back to the essential oil bottle 8. At the same time, since the atomizing core 41 is set towards the mist outlet 12, the droplets that do not enter the mist outlet 12 adhere to the inner wall of the atomizing head main housing 1 on the side close to the mist outlet 12. The eccentrically set through hole 161 makes the inclined surface close to the mist outlet 12. The area of ​​the inclined surface between the through hole 161 and the mist outlet 12 is increased, which improves the guiding effect on the droplets attached to the inner wall of the atomizing head main housing 1 on the side close to the mist outlet 12 and speeds up the return of the droplets to the essential oil bottle 8.

[0040] A nozzle 6 is provided at the output end of the mist outlet 12. The nozzle 6 blocks the output end of the mist outlet 12, and an orifice 61 is formed on the nozzle 6. By blocking the output end of the mist outlet 12 with the nozzle 6, atomized droplets are sprayed out through the orifice 61. This increases the velocity of the droplets as they flow through the orifice 61, preventing backflow of droplets at the mist outlet and increasing the mist output of the atomizing head. (Refer to...) Figure 5 As shown, the cross-sectional dimension of the nozzle 6113 is smaller than that of the mist outlet 12. Simultaneously, the increased airflow velocity reduces droplet size, resulting in smaller droplets and improved diffusion efficiency. The nozzle 6 is a semi-closed tube at one end, with its end furthest from the nozzle 61 inserted into the mist outlet 12, while the end closer to the nozzle 61 protrudes outward relative to the mist outlet 12. The nozzle 61 is offset relative to the mist outlet axis 120 towards the top of the mist outlet 12. The nozzle 61 is offset towards the top of the mist outlet 12, thus forming an air outlet channel 7 inclined towards the top of the mist outlet 12 between the lower wall of the mist outlet 12 and the nozzle 61. The droplets flow along the air outlet channel 7 and are sprayed upward relative to the axis 120 of the mist outlet, resulting in a large coverage area of ​​the area directly above the mist outlet 12. At the same time, the offset of the nozzle 61 towards the top of the mist outlet 12 increases the horizontal height of the nozzle 61 and the inclination between the lower wall of the mist outlet 12 and the nozzle 61, further reducing the angle between the extended line of the droplet spray direction and the vertical line, further increasing the coverage area of ​​the area directly above the mist outlet 12, expanding the diffusion range of the droplets, and increasing the dispersion velocity of the droplets.

[0041] The vertical line is a line perpendicular to the height direction of the atomizing head; the angle between the air outlet channel 7 and the vertical line is α, α≤60°, and in a preferred embodiment, α=60°.

[0042] The nozzle 61 is generally elongated ellipse, with its minor axis extending along the height direction; along the mist outlet direction of the mist outlet 12, the inner wall of the nozzle 6 is inclined inward, or a guide slope 62 is provided on the nozzle 6, and the guide slope 62 is provided on the inner side of the nozzle 61; along the mist outlet direction of the mist outlet 12, the guide slope 62 is inclined inward.

[0043] In a preferred embodiment, the inner wall of the nozzle 6 is inclined inward, and a guide slope 62 is provided on the nozzle 6. By providing the inwardly inclined inner wall of the nozzle 6 and the guide slope 62, the cross-sectional size of the nozzle 6 gradually narrows along the mist outlet direction of the mist outlet 12, thereby increasing the speed of the liquid passing through the nozzle 6.

[0044] In a preferred embodiment, the slope of the guide slope 62 is greater than the slope of the inner wall of the nozzle 6. As the droplet flows through the guide slope 62, the angle between the extended line of the droplet ejection direction and the vertical line is further reduced, further increasing the coverage area of ​​the droplet on the region directly above the mist nozzle 12. The angle between the guide slope 62 and the vertical line is β, β < α, β ≤ 30°; in a preferred embodiment, β ≤ 25°.

[0045] In a preferred embodiment, the nozzle 6 is embedded in the output end of the mist outlet 12. By embedding the nozzle 6 in the output end of the mist outlet 12, the connection between the nozzle 6 and the output end of the mist outlet 12 is reliable.

[0046] A receiving cavity 121 is recessed outward inside the output end of the mist outlet 12, forming a first step 122 between the receiving cavity 121 and the inner wall surface of the mist outlet 12. A second step 63 is convex outward on the outer wall surface of the nozzle 6, and is housed in the receiving cavity 121. The outer wall of the second step 63 fits against the receiving cavity 121 and abuts against the first step 122. The end of the nozzle 6 away from the second step 122 is housed in the mist outlet 12 and fits against the inner wall surface of the mist outlet 12. The abutment between the first step 122 and the second step 63 achieves the installation limitation of the nozzle 15; at the same time, the fit between the outer wall of the second step 63 and the receiving cavity 121, and the fit between the end of the nozzle 15 away from the second step 63 and the inner wall surface of the mist outlet 12, increases the contact area between the nozzle 6 and the mist outlet 12, improving the connection stability between the nozzle 6 and the mist outlet 12.

[0047] The atomizing head is mounted on the essential oil bottle 8. The atomizing core 4 is connected to an air pump. The suction tube insertion hole on the atomizing core 4 is connected to a suction tube (not shown in the figure), which extends into the essential oil bottle 8. The atomizing core 5 mixes the liquid in the essential oil bottle 8 with the air output from the air pump, atomizes it, and sprays it out of the mist outlet 12.
