Abstract
Description
Technical Field
[0001] This utility model relates to the field of air improvement equipment, and in particular to an atomizing head. 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] Essential oils have high viscosity. When the essential oil is atomized, liquid remains on the surface of the liquid outlet of the atomizer core, which then forms large droplets on the surface of the liquid outlet of the atomizer core. When the fragrance device is turned on again, the remaining large droplets will be sprayed out, resulting in a spraying phenomenon. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide an atomizing head that intercepts large droplets of liquid transported by a small flow of air, removes large droplets of liquid residue remaining in the atomizing device, avoids liquid spraying, and increases the amount of mist output while reducing the particle size of the droplets.
[0005] To solve the above-mentioned technical problems, the technical solution used in this utility model is as follows:
[0006] The present invention discloses an atomizing head, comprising an atomizing device and a mist outlet. The mist outlet is inclined upward along the height direction of the atomizing head. The atomizing device is provided with an air inlet channel, and the output end of the air inlet channel is provided with an air outlet. The air outlet is positioned opposite to the input end of the mist outlet. The air flow direction in the air inlet channel forms an angle θ with the output end of the mist outlet. The cross-sectional dimension of the air inlet channel near the air outlet is smaller than the cross-sectional dimension of the other end of the air inlet channel.
[0007] Preferably, the included angle θ is 10° < θ < 40°.
[0008] Preferably, the atomizing device has a liquid outlet hole, which is close to and forms an angle with the air outlet hole. The extension line of the plane containing the liquid outlet hole extends into the mist outlet nozzle. Preferably, it also includes a top cover, which is disposed above the atomizing device. The top cover has an opening that communicates with the outside. A ventilation channel is provided between the atomizing device and the mist outlet nozzle, and the ventilation channel communicates with the opening. The ventilation channel is used to increase the amount of air entering the mist outlet nozzle.
[0009] Preferably, there are two openings, which are symmetrically arranged about the atomizing device.
[0010] Preferably, a baffle is provided between the top cover and the atomizing device. The baffle covers the atomizing device and extends towards the mist outlet. Both sides of the baffle extend downward in the direction close to the atomizing device. A gap is provided between the baffle and the inner wall of the atomizing head. The ventilation channel is located between the baffle and the mist outlet.
[0011] Preferably, one end of the baffle partially overlaps with the mist outlet along the height direction.
[0012] Preferably, the atomizing device includes a liquid inlet channel and an atomizing channel. One end of the air inlet channel is connected to an air pump, and the other end of the air inlet channel is connected to an air outlet through a compression chamber. The liquid inlet channel is connected to a liquid suction pump. The atomizing channel is connected to the air inlet channel and the liquid inlet channel, and the liquid outlet is located at the end of the atomizing channel near the air inlet channel.
[0013] Preferably, the cross-sectional dimension of the compression chamber is smaller than the cross-sectional dimension of the end of the air intake channel connected to the air pump.
[0014] Compared with the prior art, the beneficial effects of the atomizing head described in this utility model are mainly reflected in:
[0015] The atomizing device connects to a liquid storage bottle and an air pump. It mixes the liquid in the storage bottle with the air output from the air pump, atomizes it, and sprays it out through the nozzle. By setting the assembly position of the atomizing device and the nozzle, an angle θ is formed between the airflow direction in the air inlet channel and the output end of the nozzle. This ensures that the airflow direction from the atomizing device and the output end of the nozzle are not on the same straight line. When removing large droplets remaining in the outlet of the atomizing device, the air pump connected to the atomizing device outputs a small flow of air to act on the remaining large droplets, causing them to contact the inner wall of the nozzle. The nozzle intercepts the large droplets, preventing them from being ejected. Simultaneously, the nozzle is tilted upwards along the height of the atomizing head, causing the intercepted large droplets to flow back into the storage bottle under gravity. This effectively removes large droplets remaining in the atomizing device.
[0016] The cross-sectional dimension of the air intake channel near the air outlet is smaller than that of the other end of the air intake channel; thus, the air in the air intake channel near the air outlet is compressed, increasing the air pressure, increasing the force exerted by the air on the liquid, accelerating the flow rate of the droplets to the mist nozzle, further reducing the particle size of the droplets while increasing the mist output.
[0017] Simultaneously, when a large flow of air is output through an air pump, the high flow of air atomizes the liquid. The atomized small droplets, under the influence of the high-flow air, are ejected through the mist nozzle. Because the air outlet of the atomizing device is positioned opposite the input end of the mist nozzle, the small droplets move towards the nozzle without obstruction, resulting in a larger volume of droplets entering the nozzle. This increases the number of small droplets ejected from the nozzle, thus increasing the mist output. By adjusting the assembly position of the atomizing device and the mist nozzle, the output of small droplets is increased while simultaneously intercepting large droplets.
[0018] When the air pump outputs a large flow of air to atomize the liquid, small droplets move along the extension line of the plane where the liquid outlet is located towards the mist nozzle, and extend into the mist nozzle through the extension line of the plane where the liquid outlet is located; this further increases the amount of small droplets entering the mist nozzle, and further increases the mist output.
[0019] When the atomizing device atomizes a liquid, the air pump connected to the atomizing device outputs a large flow of air to atomize the liquid into small droplets. The air carries these droplets, causing them to diffuse and flow in different directions. An opening in the top cover, connected to a ventilation channel, allows external air to flow into the atomizing head. As the air flows through the ventilation channel, the air output from the atomizing device carries surrounding air towards the mist outlet. Simultaneously, this airflow guides any small liquid droplets that haven't yet entered the mist outlet into it before they are sprayed out. This increased airflow also allows more small droplets to be sprayed out, thus increasing the atomization volume. Furthermore, the presence of two symmetrical openings further increases the amount of air entering the atomizing head.
[0020] By setting up a baffle, the baffle enhances the guiding effect of airflow, and then the air output by the atomizing device and the small droplets atomized by the air enter the mist outlet along the guiding direction of the baffle; by restricting the diffusion direction of air and small droplets by the baffle, more small droplets enter the mist outlet.
[0021] Meanwhile, one end of the baffle partially overlaps with the mist outlet along its height. One end of the baffle extends into the mist outlet; this further enhances the guiding effect on air and small liquid droplets. Simultaneously, since the baffle is positioned above the atomizing device, it can intercept large residual liquid droplets that diffuse upwards. Thus, when a small flow of air carries large residual liquid droplets towards the mist outlet, the large droplets are intercepted both laterally by the inner wall of the mist outlet and vertically by the baffle, further improving the interception effect.
[0022] This invention utilizes the matching of the atomizing device and the mist outlet to intercept large droplets transported by a small flow of air, thereby removing large droplets remaining in the atomizing device. Simultaneously, when small droplets are sprayed out, the air output by the air pump drives the air around the ventilation channel to flow towards the mist outlet, guiding the small droplets that did not enter the mist outlet into the mist outlet before being sprayed out, thus increasing the atomization volume.

[0032] 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.
[0033] 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.
[0034] This embodiment provides an atomizing head 1, which is installed on a liquid storage bottle 2. The atomizing head 1 includes an atomizing device 11 and a mist outlet 12. The mist outlet 12 is inclined upward along the height direction of the atomizing head 1. The atomizing device 11 is provided with an air inlet channel 114 and a liquid outlet 1161. The output end of the air inlet channel 114 is provided with an air outlet 1110. The air outlet 1110 is positioned opposite to the input end of the mist outlet 12. The extension line of the plane containing the liquid outlet 1161 extends into the mist outlet 12. (Refer to...) Figure 3 As shown, the airflow direction in the air intake channel forms an angle θ with the output end of the mist nozzle 12. Specifically, the airflow direction in the air intake channel and the extension line of the air outlet form an angle θ with the central axis of the mist nozzle 12. The angle θ is 10° < θ < 40°. In a preferred embodiment, the range of the angle θ is 20° < θ < 40°, specifically 22°.
[0035] By setting the assembly positions of the atomizing device 11 and the mist outlet 12, an angle θ is formed between the airflow direction in the air intake channel 114 and the output end of the mist outlet 12. This ensures that the airflow direction output by the atomizing device 11 and the output end of the mist outlet 12 are not on the same straight line. When removing large droplets remaining in the liquid outlet of the atomizing device 11, a small flow of air is output by the air pump to act on the remaining large droplets, causing them to contact the inner wall of the mist outlet 12. The mist outlet 12 intercepts the remaining large droplets, thus preventing them from being sprayed out. Simultaneously, the mist outlet 12 is tilted upwards along the height direction of the atomizing head 1, allowing the intercepted large droplets to flow back into the liquid storage bottle 2 under gravity. This effectively removes the large droplets remaining in the atomizing device 11. This prevents the aroma diffuser from spraying liquid during use.
[0036] Simultaneously, when a large flow of air is output through an air pump, the high flow of air atomizes the liquid. The atomized small droplets, under the influence of the high-flow air, are ejected through the mist nozzle. Because the air outlet of the atomizing device is positioned opposite the input end of the mist nozzle, the small droplets move towards the nozzle without obstruction, resulting in a larger volume of droplets entering the nozzle. This increases the number of small droplets ejected from the nozzle, thus increasing the mist output. By adjusting the assembly position of the atomizing device and the mist nozzle, the output of small droplets is increased while simultaneously intercepting large droplets.
[0037] When the air pump outputs a large flow of air to atomize the liquid, small droplets move along the extension line of the plane where the liquid outlet is located toward the mist nozzle, and extend into the mist nozzle 12 through the extension line of the plane where the liquid outlet is located; this further increases the amount of small droplets entering the mist nozzle 12, and further increases the mist output.
[0038] The atomizing device 11 is connected to an air pump (not shown in the figure) and a liquid suction tube (not shown in the figure), with the liquid suction tube extending into the liquid storage bottle 2; the atomizing device 11 is used to mix and atomize the liquid in the liquid storage bottle 2 with the air output by the air pump and spray it out of the mist outlet 12.
[0039] The atomizing head also includes an upper cover 13, which is disposed above the atomizing device 11. The upper cover 13 has an opening 131 communicating with the outside. A ventilation channel 14 is provided between the atomizing device 11 and the mist outlet 12, and the ventilation channel 14 communicates with the opening 131. The ventilation channel 14 is used to increase the amount of air entering the mist outlet 12. In a preferred embodiment, there are two openings 131, which are symmetrically arranged about the atomizing device 11.
[0040] When the atomizing device 11 atomizes the liquid, the air carries the small droplets as they are atomized into small particles, causing them to flow in different directions. An opening 131 is provided in the upper cover 13, which connects to the ventilation channel 14. External air flows into the atomizing head 1 through the opening 131. As the air flows through the ventilation channel 14, the air output from the atomizing device 11 carries the air around the ventilation channel 14 towards the mist outlet 12. Simultaneously, the air around the ventilation channel 14, flowing towards the mist outlet 12, guides any small liquid particles that haven't yet entered the mist outlet 12 into it before being sprayed out. Increasing the airflow also allows more small droplets to be sprayed out, further increasing the atomization volume. Furthermore, the two symmetrical openings 131 further increase the amount of air entering the atomizing head 1.
[0041] A baffle 15 is provided between the upper cover 13 and the atomizing device 11. The baffle 15 covers the atomizing device 11 and extends towards the mist outlet 12. Both sides of the baffle 15 extend downwards along the direction close to the atomizing device 11. A gap is provided between the baffle 15 and the inner wall of the atomizing head 1. The ventilation channel 14 is located between the baffle 15 and the mist outlet 12. (Refer to...) Figure 3 and Figure 5 As shown; in a preferred embodiment, the horizontal height of both sides of the baffle 15 is below the air outlet 1110 of the atomizing device 11.
[0042] By setting baffle 15, the baffle 15 enhances the guiding effect of air flow, and then the air output by the atomizing device 11 and the small droplets after being atomized by the air enter the mist outlet 12 along the guiding direction of the baffle 15; by restricting the diffusion direction of air and small droplets by the baffle 15, more small droplets enter the mist outlet 12, increasing the atomization amount.
[0043] In a preferred embodiment, one end of the baffle 15 partially overlaps with the mist outlet 12 along its height. One end of the baffle 15 extends into the mist outlet 12; this further enhances the guiding effect on air and small liquid droplets. Simultaneously, since the baffle 15 is positioned above the atomizing device 11, it can intercept upward-diffusing residual large liquid particles. Thus, when residual large liquid droplets carried by a small flow of air flow towards the mist outlet 12, they are intercepted both laterally by the inner wall of the mist outlet 12 and vertically by the baffle 15; further improving the interception effect.
[0044] The atomizing device 11 includes an atomizing core 112 and an atomizing core mounting base 113. The atomizing core mounting base 113 is mounted on the atomizing head 1, and a sealing ring is provided at the connection between the atomizing core mounting base 113 and the atomizing head 1. The atomizing core 112 is mounted on the atomizing core mounting base 113. The atomizing core 112 includes an air inlet channel 114, a liquid inlet channel 115, and an atomizing channel 116. One end of the air inlet channel 114 is connected to an air pump, and an air outlet 1110 is located at the end of the air inlet channel 114 away from the air pump. The liquid outlet 1161 is located at the end of the atomizing channel 116 near the air inlet channel 114. The liquid inlet channel 115 is connected to a liquid pump. The atomizing channel 116 communicates with the air inlet channel 114 and the liquid inlet channel 115.
[0045] In a preferred embodiment, a compression chamber 111 is provided at one end of the air inlet channel 114 near the air outlet 1110. The compression chamber 111 is connected to the air outlet 1110 and the output end 110 of the atomizing device. The cross-sectional dimension of the compression chamber 111 is smaller than the cross-sectional dimension of the end of the air inlet channel 114 connected to the air pump. By setting the compression chamber 111 to reduce the cross-sectional dimension, the air pressure is increased, thereby increasing the force exerted by the air on the liquid. This can better atomize the liquid into small droplets, further reducing the particle size of the droplets. By increasing the air pressure, more droplets can be ejected from the mist outlet 12, and the flow rate of the droplets reaching the mist outlet 12 can be accelerated, increasing the amount of droplets passing through the mist outlet 12 per unit time and increasing the mist output.
[0046] By utilizing the structure of the atomizing device 11 and the fit between the atomizing device 11 and the mist outlet 12, the mist outlet 12 intercepts large liquid droplets transported by a small flow of air, thereby removing the large liquid droplets remaining in the atomizing device 11. Simultaneously, when small liquid droplets are sprayed out, a large flow of air is output by the air pump, and the liquid is drawn in by the suction pipe. The large flow of air comes into contact with the liquid, atomizing the liquid into small liquid droplets. Thus, under the action of large flow and high pressure air, the small liquid droplets are sprayed out from the mist outlet 12.
[0047] Through the cooperation of the compression chamber 111, the opening 131, and the ventilation channel 14, the high-flow-rate and high-pressure air output from the compression chamber 111 comes into contact with the liquid, driving more droplets towards the mist outlet 12, thus achieving a first increase in atomization volume. When the air flows through the ventilation channel 14, the air output from the atomizing device 11 carries the air around the ventilation channel 14 towards the mist outlet 12, guiding small liquid particles that did not enter the mist outlet 12 into it before being sprayed out, thus achieving a second increase in atomization volume. This further increases the atomization volume ejected from the mist outlet 12.
[0048] In a preferred embodiment, the cross-sectional size of the compression chamber 111 gradually decreases along the length of the air inlet channel 114 of the atomizing device 11. By setting the compression chamber 111 to a gradually decreasing size, the air pressure continuously increases as air flows from the input end to the output end of the compression chamber 111, thereby further increasing the air pressure and reducing the droplet size while increasing the atomization volume.
[0049] In a preferred embodiment, the cross-sectional dimension of the intake channel 114 near the compression chamber 111 is smaller than the cross-sectional dimension of the other end of the intake channel 114. By providing two different cross-sectional areas in the intake channel 114, the pressure and flow velocity of the air increase as it flows through the intake channel 114. Furthermore, the force applied to the liquid increases as the air flows through the ventilation channel 14, further reducing the droplet size while increasing the mist output.
[0050] The working principle of this utility model is as follows: First, the control chip is connected to the air pump signal; then, the opening of the flow control valve in the air pump is adjusted so that the air pump outputs a small flow of air to remove the large droplets remaining in the liquid outlet 116 of the atomizing device, and the mist nozzle 12 intercepts the large droplets transported by the small flow of air; then, the opening of the flow control valve in the air pump is increased so that the air pump outputs a large flow of air to atomize the liquid into small droplets, which are then sprayed out through the mist nozzle 12.
[0051] By controlling the flow control valve opening of the air pump through the control chip, the air pump can output air at different flow rates. This allows for the removal of residual large droplets. A small flow of air is used to clear these large droplets from the liquid outlet 116 of the atomizing device, preventing them from being ejected from the nozzle. Once the residual droplets at the liquid outlet 116 of the atomizing device are cleared, a larger flow of air is then output to atomize the liquid drawn into the atomizing device.
