Description

Technical Field

[0001] The present invention relates to the technical field of negative oxygen ion manufacturing equipment, and more particularly to a negative oxygen ion generator. Background Art

[0002] A negative oxygen ion generator is a device that can generate negative air ions. It usually simulates natural phenomena such as lightning and waterfalls, and uses high-pressure air to impact liquids, causing oxygen molecules in the air to gain electrons and form negatively charged negative oxygen ions. These negative ions can absorb and settle tiny particles such as dust and bacteria in the air, purifying the air and improving environmental comfort. However, with the increase in the application scenarios of negative oxygen ion generators, although the use of air compressors to generate high-pressure air can produce more negative oxygen ions, it has a great impact on the size and weight of the device. The weight and floor space occupied by structures such as air compressors limit the use of negative oxygen ion generators.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] The core of the present invention is to provide a negative oxygen ion generator, which can provide high-concentration negative oxygen ions, has high working efficiency, simple structure, small space occupancy, and low cost, and especially contributes to improving the working efficiency of small and medium-sized negative oxygen ion generators.

[0053] Please refer to Figure 1 、 Figure 2 and Figure 3 The present application provides a negative oxygen ion generator, comprising a water holding basin 1, a support body 2, an impeller 3 and a rotating power device 5.

[0054] The water holding basin 1 is a basin structure used to store water and accommodate the support body 2, impeller 3, and rotary power device 5. Specifically, the bottom of the water holding basin 1 is used to store water. The water holding basin 1 is an open-top structure, and the support body 2, impeller 3, and rotary power device 5 can be located inside it to generate negative oxygen ions. The sidewall of the water holding basin 1 is provided with a negative oxygen ion output port, so that the negative oxygen ions generated inside the water holding basin 1 are output to the outside through the negative oxygen ion output port 11.

[0055] The support body 2 is disposed within the water-containing basin 1 and is used to support the impeller 3 and the rotary power device 5. Because the impeller 2 and the rotary power device 5 need to rotate, the support body 2 has a central hole 21. The lower end surface of the central hole 21 is provided with a plurality of grid plates 22 along the circumference of the central hole 21. The space where the grid plates 22 are located is connected to the negative oxygen ion output port 11. It should be noted that the function of the above-mentioned grid plates 22 is to receive the water thrown out by the impeller 3. Due to the large impact force of the water, when the high-speed splashing water hits the grid plates 22, small molecules of water are formed, thereby generating negative oxygen ions.

[0056] The impeller 3 is rotatably installed at the bottom of the support body 2, and the blade 31 of the impeller 3 extends at an angle with the radial direction of the impeller 3; the middle part of the impeller 3 is provided with a water guide hole 33 connected to the upper end of the water suction pipe 4, and the lower end of the water suction pipe 4 extends below the liquid surface at the bottom of the water containing basin body 1.

[0057] Compared with the traditional blade 31, the blade 31 of the present application is at an angle with the radial direction of the impeller 3, forming a blade 31 deviating from the radial direction. When the high-speed rotating power device 5 is used to control the rotation of the impeller 3, a higher-speed water flow centrifugal force can be formed in cooperation with the rotating speed of the rotating power device 5, thereby generating more negative oxygen ions and improving the generation efficiency of negative oxygen ions. For example, when the rotating speed is above ten thousand revolutions, the negative oxygen ion concentration can reach the level of millions or above.

[0058] In addition, during the rotation of the impeller 3, the airflow at the position of the blade 31 will move outward due to the centrifugal effect, so the air pressure at the center of the impeller 3 will decrease, causing a siphon effect on the water suction pipe 4, which will suck the water at the lower end of the water suction pipe 4 upward and to the upper end of the water suction pipe 4, that is, the middle part of the impeller 3. At this time, the rotating impeller 3 will perform a centrifugal operation on the water sucked up, so that the water is thrown out by centrifugal force and finally thrown to the grid plate 22.

[0059] The output end 53 of the rotating power device 5 is transmissionally connected to the impeller 3, and can be connected to the receiving end 34 of the impeller 3. The receiving end 34 can be a mounting hole for driving the impeller 3 to rotate by the output end 53. When the impeller 3 rotates to generate negative pressure, the water suction pipe 4 can suck the water at the bottom of the water containing basin body 1 to the impeller 3 and throw it to the grid plate 22 by the impeller 3. Since the space where the grid plate 22 is located is in communication with the negative oxygen ion output port 11, the negative oxygen ions generated at the grid plate 22 can smoothly overflow to the negative oxygen ion output port 11.

[0060] The negative oxygen ion generator provided by the present application controls the rotation of the impeller 3 by the rotating power device 5 to generate negative pressure, which acts on the water suction pipe 4 to suck the water at the lower part to the impeller 3, and applies centrifugal force to the water by rotation to throw it to the grid plate 22, so as to impact to form negative oxygen ions, which are then output through the negative oxygen ion output port 12. Since the impeller 3 with the blade 31 deviating from the radial direction is used, the thrown water can better align with the grid plate 22, generating a large amount of negative oxygen ions.

[0061] Compared with the prior art method of using an air compressor to form gas to impact water, the negative oxygen ion generator provided by the present application can obtain a high-intensity rotation speed by adopting a high-speed rotating power device 5, thereby forming a siphon effect in the water suction pipe 4, and then the water is thrown out by the impeller 3 to collide with the grid plate 22 to obtain negative oxygen ions, which saves the space for setting up the air compressor and reduces the overall weight. In addition, the efficiency of negative oxygen ion generation is improved through the cooperation of high rotation speed. For example, when the rotation speed is above 10,000 rpm, the concentration of negative oxygen ions can reach one million or more.

[0062] The negative oxygen ion generator provided in this application can provide high-concentration negative oxygen ions, and has high working efficiency, simple structure, small space occupation, and low cost, and has made a significant contribution to improving the working efficiency of small and medium-sized negative oxygen ion generators.

[0063] In a specific embodiment, the support body 2 is a cylindrical structure, and the cylindrical support body 2 may have a stepped central hole 21 for arranging the rotary power device 5. The cylindrical structure includes the aforementioned grating plate 22. The lower portion of the support body 2 is used to accommodate the impeller 3. The impeller 3 and the grating plate 22 are located at the same axial position of the central hole 21, thereby ensuring that centrifugal water droplets from the impeller 3 are thrown onto the grating plate 22.

[0064] Optionally, an air inlet 23 is provided on the upper portion of the support body 2. This device uses a siphon effect to generate negative oxygen ions from the internal water and discharge them out of the negative oxygen ion output port. To ensure the stability of the overall air pressure, a passive internal air supply structure is required. If this structure is placed on the water container, it is easy to cause the negative oxygen ions to mix with air. Therefore, the air inlet 23 can be placed between the intersecting gaps on the rotary power device and the support body, from the periphery of the rotary power device, from top to bottom, in the axial direction, directly to the center of the impeller. The distance from the siphon port is about 5 mm.

[0065] On the basis of the above embodiment, the impeller 3 includes a bottom plate 32 and blades 31 . The bottom plate 32 is provided with a water inlet hole 33 , and a plurality of blades 31 are circumferentially arranged around the water inlet hole 33 .

[0066] It should be noted that the impeller in this application is primarily used to guide water flow and provide centrifugal force for the water flow, requiring the base plate 32 to provide support for the water flow. The water inlet holes 33 provided on the base plate 32 are connected to the water suction pipe 4. As the impeller 3 rotates, causing the air pressure in the middle (i.e., at the blade roots) to drop, the air pressure in the upper portion of the water suction pipe 4 also drops, thereby creating a siphon effect in the water suction pipe 4. The blades 31 in this embodiment are arranged around the water inlet holes, accurately transmitting the negative pressure at the base of the blades 31 to the water inlet holes 33, thereby accurately causing the water suction pipe 4 to perform a siphon effect.

[0067] Optionally, there may be only one water inlet hole 33, and the centerline of the water inlet hole 33 may be collinear or non-collinear with the centerline of the impeller 3. The water inlet hole 33 is disposed in the middle of the bottom plate 32, so that the water suction pipe 4 is located in the middle of the bottom plate 32, thereby preventing the water suction pipe 4 from rotating over a large range when the impeller 3 rotates.

[0068] Based on any of the above embodiments, the blades 31 are linear blades, and any two adjacent blades 31 have the same angle with the radial direction of the impeller 3 and the same deflection direction.

[0069] It should be noted that linear blades include flat blades or airfoil-shaped blades. When blade 31 is a linear blade, the blade root serves as the starting point of the blade 31's extension direction, and the blade edge serves as the end point of the blade 31's extension direction. The length of blade 31 is the distance from the starting point to the end point. The length of blade 31 forms an angle with the radial direction of the starting point, also known as the deflection angle. Around the impeller, the deflection direction of blades 31 is the same, meaning that all blades 31 deflect counterclockwise (or clockwise) relative to their starting point. In other words, any two adjacent blades have the same deflection direction, i.e., the same rotation direction.

[0070] For straight blades, the grating plates 22 on the support body 2 can be arranged in a one-to-one or non-one-to-one correspondence. Optionally, the grating plates 22 are evenly arranged in the circumferential direction, so that when the impeller 3 rotates, a greater centrifugal force can be obtained than that of curved blades, accelerating the impeller 3 toward the grating plates 22, thereby obtaining a large amount of negative oxygen ion concentration that is relatively uniform overall.

[0071] Optionally, the grating plates 22 disposed circumferentially on the bottom surface of the support body 2 may have the same deflection angle relative to the central hole 21. In other words, to maximize the surface area of ​​the grating plates 22 receiving the water droplets ejected by the centrifugal action of the blades 31, the grating plates 22 should be oriented as closely as possible in the direction of the water droplet ejection. If the angles and shapes of the blades 31 are the same on the circumferential surface, the grating plates 22 should also have the same angle.

[0072] Optionally, the grating plate 22 may be a straight plate, preferably arranged perpendicularly to the corresponding blade 31. It should be noted that the correspondence mentioned here should be understood as having corresponding vertical blades in the non-rotating state, or that in the rotating state, the blade 31 corresponding to the water droplets received by the grating plate 22 is the corresponding blade. In actual production, this correspondence is also related to the rotational speed of the impeller 3 driven by the rotary power device and the size of the blade 31.

[0073] Optionally, the grid plate 22 may be a convex panel protruding toward the blades 31. The convex panel is more likely to contact the centrifuged water droplets and has an outward splashing angle, thereby obtaining more negative oxygen ions. Specifically, the grid plate 22 is a curved panel or a spherical panel.

[0074] Optionally, the grid plate 22 may be a panel with a complex surface, such as a serrated surface, a stepped surface, etc. The purpose of setting the above panel shape is to produce greater contact and collision with the centrifugal water droplets, thereby generating more negative oxygen ions.

[0075] Based on any of the above embodiments, the blades 31 are curved blades with a fixed curvature, and the curvatures of any two adjacent blades are the same;

[0076] Alternatively, the blade 31 is a curved blade with a variable curvature, and the curvature of the blade 31 along the radial direction of the base plate changes uniformly.

[0077] It should be noted that curved blades include arc blades, flat curved blades, etc.

[0078] The characteristic of the above-mentioned curved blades is that the line connecting the blade root to the blade edge varies along the length of the blade. These blades include forward-curved blades and backward-curved blades. The former has a larger absolute velocity and circumferential component velocity at the outlet, and the impeller 3 also performs the greatest work on the fluid, but has larger flow losses. Especially when the circumferential velocity of the impeller 3 is high, it is prone to large flow losses, which may lead to a decrease in overall efficiency. The latter has a smaller absolute velocity and circumferential component velocity at the outlet, resulting in smaller flow losses and, therefore, higher stage efficiency. The compressor stage with backward-curved blades completes pressure increase in the impeller 3, where flow losses are relatively low, resulting in higher overall efficiency. Therefore, it is suitable for applications requiring high efficiency, especially when the circumferential velocity of the impeller 3 is high, where it can maintain a high stage efficiency. For the curved blades provided above, the grid plate also needs to be coordinated with the direction of ejection of the water droplets, so that the water droplets can generate a large amount of negative oxygen ions when they collide with the grid plate.

[0079] Based on any of the above embodiments, the support body 2 and the grid plates 22 are integrally formed, and each grid plate 22 is arranged perpendicular to the bottom of the support body 2. The integrally formed structure facilitates manufacturing and ensures the stability of the position of the grid plates 22, preventing deflection or other position changes caused by water droplets hitting them.

[0080] Optionally, the above-mentioned one-piece molding structure can be produced by other methods such as 3D printing or casting.

[0081] Based on any of the above embodiments, the bottom of the support body 2 is a groove structure 24 facing the bottom of the water basin 1, the grid plate 22 is located on the inner bottom surface of the groove structure 24, and the middle hole 21 is located in the middle of the groove structure 24; the impeller 3 is located in the groove structure 24; and further includes a limit plate 6 for limiting the axial position of the impeller 3, the limit plate 6 having a through hole 61 for the suction pipe 4 to pass through, and the limit plate 6 is detachably connected to the mounting portion 26 at the bottom of the support body 2 by a connecting member; optionally, the connecting member can be a mounting structure such as a screw, a bolt, or a clamp;

[0082] When the limiting plate 6 is installed, a first gap 25 is formed between the limiting plate 6 and the bottom end of the support body 2 , so that the negative oxygen ions at the grid plate 22 can overflow to the negative oxygen ion output port 11 .

[0083] On the basis of any of the above embodiments, a limiting plate water inlet hole 62 is provided on the limiting plate 6, and the limiting plate water inlet hole 62 is used to guide the unbroken water droplets back to the bottom of the water holding basin 1. It is a connecting structure connecting the space where the blades 31 are located and the water storage space at the bottom of the water holding basin 1, and is used to allow excess water droplets on the bottom plate 32 that have not formed negative oxygen ions to return to the water storage space. Optionally, other gaps or channels for water reflux may also exist between the support body 2 and the impeller 3.

[0084] Based on any of the above embodiments, the support body 2 is placed in the water basin body 1 when connected to the limiting plate 6, and the upper port of the water basin body 1 is sealed. The outer periphery of the limiting plate 6 is fitted with the inner wall of the water basin body 1 to divide the inner cavity of the water basin body 1 into an upper cavity 12 and a lower cavity 13. The support body 2 is located in the upper cavity 12, and the lower part of the water suction pipe 4 passes through the through hole 61 and is located in the lower cavity 13.

[0085] Based on any of the above embodiments, the rotary power device 5 is a motor, and the rotary power device 5 is mounted on the support body 2 via a first bearing 51, and the impeller 3 is connected to the support body 2 via a second bearing 52. Using bearings to mount the motor facilitates accurate positioning of the motor and ensures that the motor does not deviate from its axis during operation.

[0086] Based on any of the above embodiments, the suction pipe 4 and impeller 3 are integrally formed, eliminating the gap between the suction pipe 4 and impeller 3, resulting in a more stable and efficient siphon effect. Considering that the impeller 3 is driven to rotate by the rotary power device 4 in this application, the suction pipe 4 is also driven to rotate. On this basis, the suction pipe 4 can be positioned at the rotation center of the impeller 3 and integrally formed with the impeller 3.

[0087] Based on any of the above embodiments, the suction pipe 4 is of a straight cylindrical or inverted trapezoidal shape, with at least two water outlets 41 at its upper end. A water inlet hole 33 is provided between any two blades 31, and the water outlets 41 are correspondingly connected to the water inlet holes 33. The suction pipe 4 and the impeller 3 are integrally formed. Optionally, considering the need for rotation of the suction pipe 4, the suction pipe 4 can be configured as a straight cylindrical structure or an inverted trapezoidal structure (similar to a cone). Compared to other types of tubular structures, the inverted trapezoidal suction pipe can maintain a good rotational centerline, reducing unnecessary rotational inertia or increased load.

[0088] In addition to the main structure and connection relationship of the negative oxygen ion generator provided in the above embodiments, the structures of other parts of the negative oxygen ion generator can be referred to the prior art and will not be described in detail herein.

[0089] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

The description of the above embodiments is only used to help understand the method and core ideas of the present invention.
