Abstract
Description
Technical Field
[0001] This utility model relates to the field of negative ion technology, and in particular to a negative ion generating device. Background Technology
[0002] A negative ion generator is a device that generates negative air ions. Currently, traditional negative ion generators have the following significant drawbacks in practical applications: First, their core structure relies on an external power drive system, requiring a water pump or pressurization device to actively deliver water to achieve gas-liquid mixing. This not only leads to high energy consumption but also increases the structural complexity of the device. Second, due to the design characteristics of forced convection, the contact time between gas and liquid is short, resulting in uneven mixing and directly affecting the efficiency of negative ion generation. Furthermore, high-speed water or airflow generates significant noise pollution when impacting the inner wall of the device, affecting the user experience. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a negative ion generator with a simple structure, high negative ion production efficiency, and low noise.
[0004] Therefore, the technical solution of this utility model is: a negative ion generating device, including an air inlet, an impactor, and an impact chamber. The impactor is placed inside the impact chamber, and the air inlet extends into the impact chamber and abuts against the impactor. The air inlet is provided with an air inlet channel, and the impactor is provided with a baffle, with the two positioned opposite each other. The impact chamber is provided with a water inlet and a negative ion outlet, and the water inlet and the negative ion outlet are connected through a gas-water mixture flow channel between the air inlet and the impact chamber.
[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the water inlet is located at the bottom of the impact chamber, and the negative ion outlet is located at the top of the impact chamber; the impact component is placed at the bottom of the impact chamber, inside the water inlet.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the air intake component has a slender air intake column in the middle, the inside of the air intake column is an air intake channel, and the bottom of the air intake channel has a conical structure, that is, the bottom diameter of the air intake channel is smaller than the top diameter of the air intake channel.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the outer side of the air intake column is provided with several evenly distributed partition plates to separate multiple air-water mixture channels; the inner wall of the impact chamber is provided with vertically arranged positioning grooves, and the outer edge of some partition plates can extend into the positioning grooves.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: an arc-shaped plate is provided between adjacent partition plates, the arc-shaped plate is located above the air intake column, and the outer side of the arc-shaped plate is provided with longitudinally arranged ribs; the ribs are opposite to the negative ion outlet position at the top of the impact chamber.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the top edge of the impact component is provided with multiple first notches, and the lower edge of the partition plate of the air intake component can be inserted into the first notches.
[0010] Based on the above scheme and as a preferred embodiment of the above scheme: several sidewalls are evenly arranged on the circumference of the impact member, and the bottom of the sidewalls is connected to the stop block by a connecting rod.
[0011] In use, the negative ion generator is placed inside the water tank, with airflow at the top of the air inlet. Because the bottom of the air inlet channel has a conical structure, the gas forms a high-speed airflow after passing through the small-diameter outlet at the bottom of the air inlet channel. According to Bernoulli's principle, for flow at the same height, the greater the velocity, the lower the pressure. Therefore, the air pressure at the bottom outlet of the air inlet channel is low, creating a pressure difference with the outside of the impact chamber. This allows pure water to enter the impact chamber through the water inlet at the bottom. Simultaneously, the baffle at the bottom of the impactor is located directly below the air inlet channel. The high-speed airflow from the air inlet channel directly impacts the baffle, causing the gas to diffuse outwards. Upon contact with the pure water, the gas carries the water along to impact the side wall of the impactor, generating negative ions. The gas-water mixture carries the negative ions along the gas-water mixture flow channel, ultimately releasing them from the negative ion outlet above the impact chamber. The raised ribs on the outer side of the arc-shaped plate on the air inlet help to reduce the water flow speed and noise.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The conical air intake channel is used to enhance the airflow velocity at the bottom, creating an internal and external air pressure difference. The automatic water intake operation is then completed through this air pressure difference, eliminating the need for external water pumps or pressurization equipment, thus simplifying the equipment and reducing its cost.
[0014] An impactor is installed below the water inlet channel. After the high-speed airflow collides with the baffle, it spreads in four directions and carries the incoming water to impact the side wall of the impactor, which can significantly improve the negative ion production rate.
[0015] An arc-shaped plate is provided at the upper end of the air intake. The convex rib structure on the arc-shaped plate can disperse the impact of water flow, effectively suppress the noise generated by high-speed fluid hitting the inner wall, and improve the user's comfort.

They are only for the convenience of describing this utility model and simplifying the description, 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. They should not be construed as limiting the specific protection scope of this utility model.
[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.
[0027] See the attached drawings. The negative ion generating device described in this embodiment includes an air inlet 1, an impactor 2, and an impact chamber 3. The air inlet 1 has a slender air inlet column 11 in the middle, and the inside of the air inlet column 11 is an air inlet channel 12. The bottom of the air inlet channel 12 is a conical structure 13, that is, the diameter decreases towards the bottom of the air inlet channel 12. Several evenly distributed partition plates 14 are provided on the outside of the air inlet column 11. An arc-shaped plate 15 is provided between adjacent partition plates 14. The arc-shaped plate 15 is located above the air inlet column 11, and the outside of the arc-shaped plate 15 is provided with longitudinally arranged protruding ribs 16.
[0028] The impact member 2 has a stop block 21 in the middle, and several side walls 22 are evenly arranged on the circumference of the impact member 2. The bottom of the side walls 22 is connected to the stop block 21 through a connecting rod 23, so that the bottom of the impact member 2 is a hollow structure. At the same time, the top edge of the impact member 2 is provided with multiple first notches 24.
[0029] The impact chamber 3 is cylindrical in shape, with a water inlet 31 at the bottom and a negative ion outlet 32 at the top edge. The impactor 2 is placed at the bottom of the impact chamber 3, and the bottom of the air inlet 1 extends into the impact chamber 3 and abuts against the impactor 2. The lower edge of the partition plate 14 of the air inlet 1 can be inserted into the first notch 24. The inner wall of the impact chamber 3 is provided with a vertically arranged positioning groove 33, and part of the outer edge of the partition plate 14 can extend into the positioning groove 33 for positioning. At the same time, the partition plate 14 on the outside of the air inlet 1 can divide the space between the air inlet 1 and the impact chamber 3, creating multiple air-water mixture channels for connecting the water inlet 31 and the negative ion outlet 32.
[0030] When in use, the negative ion generator is placed in the water tank, and air is introduced at the top of the air inlet 1 (the gas is indicated by the dashed arrow). Since the bottom of the air inlet channel 12 is a conical structure 13, the gas will form a high-speed airflow after passing through the small-diameter outlet at the bottom of the air inlet channel 12. According to Bernoulli's principle: when flowing at the same height, the greater the flow velocity, the smaller the pressure. Therefore, the air pressure at the bottom outlet of the air intake channel 12 is low, creating a pressure difference with the outside of the impact chamber 3. This allows pure water to enter the impact chamber 3 from the water inlet 31 at the bottom (the water flow is indicated by a hollow arrow). Simultaneously, the baffle 21 at the bottom of the impactor 2 is located directly below the air intake channel 12. The high-speed airflow from the air intake channel 12 directly impacts the baffle 21 of the impactor 2, causing the gas to diffuse outwards. Upon contact with the pure water, the gas carries the water to impact the side wall 22 of the impactor 2, generating negative ions. Simultaneously, the gas-water mixture carries the negative ions along the gas-water mixture flow channel (the gas-water mixture is indicated by a thick arrow), ultimately flowing out from the negative ion outlet 32 above the impact chamber 3, releasing negative ions. The protruding ribs 16 on the outer side of the arc plate 15 on the air intake component 1 help to reduce the water flow speed and decrease the noise generated by the water flow.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
