Description

TECHNICAL FIELD

[0001] The utility model relates to negative ion generating technical field, more specifically, the utility model relates to a negative ion generator. BACKGROUND

[0002] In modern life, the influence of air quality on health is increasingly valued, and the demand for air purification means continues to grow. Negative ion technology has become one of the core technologies of many air purification devices due to its significant effects on improving air quality, removing dust and bacteria, and improving air freshness. Under this trend, negative ion generators, as a portable and innovative air purification tool, have emerged as the times require, but their development still faces many challenges.

[0003] Current negative ion generators on the market have many defects in structure design and function implementation. On the one hand, although some products have tried to introduce negative ion technology, the core component design is rough, such as unreasonable gas pipeline layout, which results in low gas delivery efficiency and cannot provide sufficient and stable airflow for negative ion generation; the impact piece structure is simple, which makes it difficult to effectively promote the full collision of gas and water molecules, resulting in a negative ion production far below expectations, which cannot quickly purify the surrounding air in a limited space and cannot meet the urgent needs of users for immediate improvement of air quality.

[0004] On the other hand, there are serious deficiencies in overall performance optimization and user experience. In terms of noise control, the gas flowing in the cup and interacting with each component produces a lot of noise interference due to the lack of effective noise reduction structure design. This not only destroys the quiet atmosphere of the use environment, but also may damage the user's hearing in a long-term noisy environment, reducing their use comfort and product satisfaction.

[0005] Therefore, a negative ion generator capable of reducing noise and generating a large amount of negative oxygen ions is proposed. SUMMARY

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a negative ion generator to solve the problems raised in the background art.

[0007] To achieve the above object, the utility model provides the following technical scheme: A negative ion generator, cup body is provided with base on inside bottom end, is connected with overflow cover on base, is inserted with gas pipeline in overflow cover inside, is installed with impact piece on overflow cover inside bottom end, is provided with filter water grid of annular arrangement on overflow cover, is provided with spacer tube coaxially in inside, a plurality of gas vents are arranged in annular on the top end of spacer tube, the bottom end of spacer tube and the base are provided with through -hole, the bottom end of gas pipeline is inserted in impact piece, is provided with water baffle near the end of gas pipeline, the top end of cup body is connected with upper cover, one side of upper cover is provided with insertion tube, is inserted with air inlet pipe in insertion tube, air inlet pipe and gas pipeline are communicated in the inside of upper cover, the other side of upper cover is provided with air outlet pipe.

[0011] Preferably, a plurality of exhaust holes are annularly formed in the spacer sleeve, and the third sound attenuation cavity and the fourth sound attenuation cavity are communicated through the exhaust holes.

[0012] Preferably, the impact piece comprises a base frame and a plurality of baffles, and the plurality of baffles are annularly arranged on the base frame.

[0013] Preferably, a baffle is fixedly connected to the air inlet pipe, a press switch is arranged on the top end of the baffle, the press switch is connected with a lock hook, and a lock plate matched with the lock hook is arranged in the upper cover.

[0014] Preferably, an end head is arranged at the bottom end of the second sound attenuation cavity, a hose is arranged on the end head, and the bottom of the hose abuts against the top of the gas pipeline.

[0015] Preferably, a water injection groove is arranged on the top end of the upper cover.

[0016] Preferably, a panel is further arranged on the upper cover.

[0017] The utility model discloses the technical effect and advantage:

[0018] 1. Compressed gas enters the gas delivery pipeline through the intake pipe and silencer chamber. At the bottom of the gas delivery pipeline, it interacts with the impactor and water, generating negative oxygen ions based on the Lenard effect, which can purify the air and improve the breathing environment.

[0019] 2. By setting up multiple silencing chambers, when the gas flows in the first and second silencing chambers, the baffles and chamber structure reduce the intake noise; when the gas is discharged, it passes through the baffle, the partition and each silencing chamber, further reducing the noise and creating a quiet operating environment for users.

[0020] 3. The baffle plate can collect water droplets to prevent excessive discharge. The dual channels it forms help remove gas droplets and enhance noise reduction. The slow water chamber at the bottom of the overflow cover collects and buffers the external drainage flow to prevent excessive water bubbles and ensure that the area around the cup is dry and clean.

[0021] 4. The intake pipe is easy to install and remove by using a push-button switch in conjunction with a locking hook and locking plate. The push-button switch is easy to operate, and the locking hook and locking plate are firmly connected, ensuring safe and stable use and facilitating the maintenance and replacement of intake components.

[0022] 5. The pressure difference between the vent holes in the inner tube of the overflow cover and the through holes at the bottom of the overflow cover creates a pressure difference for drainage. This allows the gas to mix with an appropriate amount of water and impact the impactor to efficiently generate negative ions. The filter plate diverts water flow, reduces noise, and improves the stability of ion generation. All components work together to improve the overall performance of the cup and the user experience.

[0035] Embodiment 2

[0036] As shown in the accompanying Figures 2-8As shown, the utility model provides a second embodiment of a negative ion generator, including cup body 1, cup body 1 inside bottom end is provided with base 2, base 2 top end is connected with overflow cover 3, overflow cover 3 inside is inserted with gas pipeline 4, overflow cover 3 inside bottom end is installed with impact piece 6, overflow cover 3 is provided with annular arrangement filter water grid 26, inside coaxial is provided with spacer 27, spacer 27 top end is annular and is provided with multiple gas holes 25, spacer 27 bottom end and base 2 all are provided with through -hole 24, wherein, impact piece 6 is arranged in spacer 27, the inner diameter size of gas hole 25 is less than the inner diameter size of through -hole 24.

[0037] Filter disc 5 is sleeved on gas pipeline 4, gas pipeline 4 bottom end is inserted in impact piece 6, gas pipeline 4 top end is connected with water baffle 7, cup body 1 top end is screwed with upper cover 8, one side of upper cover 8 is provided with insertion pipe, insertion pipe is inserted with air inlet pipe 9, the other side of upper cover 8 is provided with air outlet pipe 10, the inside top end of upper cover 8 is provided with baffle 11, baffle 11 both sides are separated into first sound attenuation chamber 12 and second sound attenuation chamber 13 respectively, second sound attenuation chamber 13 is communicated with gas pipeline 4, spacer 14 is pressed solid between upper cover 8 and overflow cover 3, the third sound attenuation chamber 15 is surrounded by the bottom of spacer 14 and the inside top end of overflow cover 3, the fourth sound attenuation chamber 16 is surrounded by the spacer 14 and the upper cover 8, the fourth sound attenuation chamber 16 is communicated with the air outlet pipe 10, the water buffer chamber 17 is surrounded by the bottom of overflow cover 3 and the base 2, and the sealing cover 18 is fixedly connected to the top end of the upper cover 8.

[0038] Specific implementation, compressed gas enters from air inlet pipe 9, passes through first sound attenuation chamber 12, passes through intermediate baffle 11, enters second sound attenuation chamber 13, and then enters gas pipeline 4 from second sound attenuation chamber 13, the lower end of gas pipeline 4 is reduced in cross-sectional area, thereby changing the flow rate of compressed gas, so that the flow rate around the bottom of gas pipeline 4 increases and the pressure decreases, so that when the compressed gas is discharged, it is blocked by the bottom plane of impact piece 6, i.e. the bottom bracket, and the gas is discharged outward, and because the inner diameter of the upper gas hole 25 is smaller than the diameter of each through hole 24, the upper pressure is high and the bottom pressure is low, forming a pressure difference, so that the water in the spacer 27 is discharged, and the remaining water and gas impact the baffle at high speed, and because of the impact, there is a water flow sound, so that the filter disc 5 is arranged to split and relieve the rapid water flow, so as to achieve the effect of noise reduction, and the water and gas impact the baffle, according to the Leonard effect, negative oxygen ions are formed, the negative oxygen ions enter the fourth sound attenuation chamber 16 from the gas hole 25 above the spacer 27, and then enter the fourth sound attenuation chamber 16 for further noise reduction and then discharge from the air outlet pipe 10, so that the negative oxygen ions can purify the air and improve the breathing environment.

[0039] When the water and gas inside are discharged together, the water beads are condensed and fall at the baffle 7, so as to avoid a large amount of water beads from being discharged, and since the baffle 7 separates the annular overflow holes at the top of the overflow cover 3 into two channels, the gas can enter the third sound attenuation cavity 15 through the two channels when passing through the baffle 7, so as to further remove the water beads in the gas and further attenuate the sound, and after the gas enters the third sound attenuation cavity 15, the top spacer sleeve 14 plays a role of filtering the condensed water and forms a fourth sound attenuation cavity 16 to further reduce the noise of the discharged gas; the bottom water buffering cavity plays a role of collecting water and relieving the water bubbles when the water is discharged, and when the water is discharged, the water can be discharged downward into the cavity between the overflow cover 3 and the cup body 1 through the through hole 24.

The connecting hole is arranged on the baffle 11 to connect the first sound attenuation cavity 12 and the second sound attenuation cavity 13, so as to play a role of attenuating the sound of the inlet gas.

[0041] The spacer sleeve 14 is annularly arranged with a plurality of exhaust holes, and the third sound attenuation cavity 15 and the fourth sound attenuation cavity 16 are connected through the exhaust holes.
