Description

Technical Field

[0001] This utility model relates to the field of negative oxygen ion technology, and in particular to a water ionization structure and a water negative oxygen ion generator that improves water detection sensitivity. Background Technology

[0002] Negative oxygen ions have an air-purifying effect and can effectively optimize air quality. However, the water-based negative oxygen ion generators currently on the market are mainly of two types: water-jet generation and mesh piezoelectric ceramic atomization. The former produces a lower number of negative oxygen ions, has a shorter migration distance, and is noisier, while the latter's mesh is prone to clogging, has a shorter lifespan, and poor sealing, making it prone to leakage.

[0003] Prior patent CN118935597A discloses a device for generating negative oxygen ions from water. While this existing technology can increase the generation of negative oxygen ions by combining static ionization of the water tank, ultrasonic atomization, and high-voltage ionization, and by adding a fan to increase the migration distance of the negative oxygen ions, the atomizing plate constantly splashes water droplets during operation. These droplets land on the water level sensor at the bottom of the atomizing water tank, causing the water level sensor to generate a continuous water detection signal, which poses a risk of water detection failure. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a water ionization structure and a water negative oxygen ion generator to improve water detection sensitivity. It can improve water detection sensitivity and enhance the ionization effect in the atomization cavity, thus preparing for the atomization fineness of the ultrasonic ceramic transducer.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a water ionization structure to improve water detection sensitivity, which is installed in a water negative oxygen ion generator. The water negative oxygen ion generator includes a water storage tank, an atomizing water tank and a negative charge output device. The atomizing water tank is provided with an atomizing chamber, and the bottom of the atomizing chamber is provided with an ultrasonic ceramic transducer and a water level detection device.

[0006] The water ionization structure is a cover with an open bottom. The cover is located at the bottom of the atomizing chamber and covers both the ultrasonic ceramic transducer and the water level detection device. The cover is made of plastic material mixed with mixed rare earth ionization material. The plastic material can be ABS or PP plastic. The top surface of the cover has a first through hole corresponding to the position of the ultrasonic ceramic transducer to allow water mist to pass through. The cover has an isolation cavity to separate the ultrasonic ceramic transducer and the water level detection device. The top surface of the isolation cavity is a sealed surface.

[0007] In a preferred embodiment, the top surface of the cover is further provided with a plurality of second through holes, the second through holes being smaller than the first through holes.

[0008] In a preferred embodiment, the isolation cavity consists of a baffle disposed within the enclosure, a portion of the top surface of the enclosure surrounded by the baffle, and a portion of the side surface of the enclosure; the baffle is positioned between the ultrasonic ceramic transducer and the water level detection device.

[0009] In a preferred embodiment, the baffle is an arc-shaped plate, and the baffle and the cover are integrally formed.

[0010] In a preferred embodiment, the baffle is an arc-shaped plate bent toward the direction of the ultrasonic ceramic transducer, which makes the structure more robust and ensures the stability of the water ionization structure.

[0011] In a preferred embodiment, the atomizing chamber is provided with an air inlet; the cover is a cylindrical structure with a flat side facing the air inlet to provide installation space for the air inlet; the side wall of the cover includes several arc-shaped support parts supported on the bottom surface of the atomizing chamber, which facilitates assembly.

[0012] In a preferred embodiment, the water storage tank is connected to the inlet of the atomizing water tank; the bottom of the side wall of the cover facing the inlet is provided with an arc-shaped opening, and the bottom sides of the baffle are provided with opening slots to allow water to flow from the water storage tank into the atomizing chamber.

[0013] A water negative oxygen ion generating device includes a water ionization structure as described in any of the above technical solutions to improve water detection sensitivity.

[0014] In a preferred embodiment, the negative charge output device includes a conical tube, a fan bracket, and a silent fan. The silent fan is mounted on the fan bracket, and the front end of the fan bracket is provided with a needle holder that can be inserted into the conical tube. A negative charge output needle is installed on the front end ring of the needle holder. The fan bracket is fixedly connected to the rear end of the conical tube so that the air outlet of the silent fan is aligned with the opening at the rear end of the conical tube, and the negative charge output needle is located at the outlet position at the front end of the conical tube.

[0015] In a preferred embodiment, the top of the atomizing water tank is symmetrically provided with two mist outlets, each mist outlet being detachably connected to a mist outlet pipe, and the outlets of the two mist outlet pipes are symmetrically located on both sides of the outlet of the conical pipe.

[0016] Furthermore, the two mist outlet pipes are connected as one unit by an arc-shaped mounting part. The arc-shaped mounting part has at least one mounting hole on each side of each mist outlet pipe, and mounting seats that mate with the mounting holes are provided on both sides of the two mist outlets. The two mist outlet pipes are connected to the two mist outlets through the arc-shaped mounting part.

[0017] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention provides a water ionization structure that can be placed in an atomization chamber. An isolation chamber separates the ultrasonic ceramic transducer from the water level detection device. The top surface of the isolation chamber is a sealed surface, creating a relatively sealed space that can accommodate the water level detection device. This prevents water splashed during ultrasonic transducer atomization from falling onto the water level detection device, effectively preventing false readings caused by water droplets on the device and improving water level detection sensitivity. Simultaneously... The water ionization structure incorporates mixed rare-earth ionizing materials, which can ionize the water in the atomization chamber into small water molecule clusters. This provides a basis for finer atomization and the carrying of more negative charges by the ultrasonic ceramic transducer, thereby enhancing the ionization effect in the atomization chamber. In addition, the ultrasonic transducer creates tension height during atomization, causing water to splash up and form droplets. When these droplets fall into the atomization chamber, they create noise. The aforementioned water ionization structure reduces this noise by setting multiple second through holes on the top surface, allowing the water droplets to fall onto the perforated plane.

[0019] A water negative oxygen ion generator employs the aforementioned water ionization structure to improve water detection sensitivity. This structure can prevent water droplets from splashing onto the water level detection device, thereby improving water detection sensitivity. Furthermore, the water ionization structure can ionize the water in the atomization chamber, thereby enhancing the ionization effect within the atomization chamber.

[0034] Reference Figure 1-9This invention describes a water ionization structure 1 and a water negative oxygen ion generator 2 for improving water detection sensitivity according to an embodiment of the present invention. The water negative oxygen ion generator 2 can be widely used to improve air quality in home environments or office spaces.

[0035] In one embodiment, such as Figure 1-7 As shown, a water ionization structure 1 for improving water detection sensitivity is installed in a water negative oxygen ion generator 2. The water negative oxygen ion generator 2 includes a water storage tank 21, an atomizing water tank 22, and a negative charge output device 23. The atomizing water tank 22 has an atomizing chamber, and the bottom of the atomizing chamber is equipped with an ultrasonic ceramic transducer and a water level detection device 24. The water storage tank 21 is connected to the atomizing water tank 22 to supply water to the atomizing chamber. The water is atomized by ultrasonic vibration to form water mist. When the water level detection device 24 is used to detect the water level in the atomizing water tank 22, an alarm signal is sent when the water level is lower than the alarm threshold.

[0036] The water ionization structure 1 is a cover with an open bottom. The cover is located at the bottom of the atomizing chamber and covers both the ultrasonic ceramic transducer and the water level detection device 24. The cover is made of plastic material mixed with mixed rare earth ionization material. The plastic material can be ABS or PP plastic. The top surface of the cover has a first through hole 11 corresponding to the position of the ultrasonic ceramic transducer to allow water mist to pass through. The cover has an isolation cavity 13 for separating the ultrasonic ceramic transducer and the water level detection device 24. The top surface of the isolation cavity 13 is a sealed surface.

[0037] The cover can be made of plastic material with added mixed rare earth ionized material during injection molding. The mixed rare earth ionized material includes mixed rare earth and tourmaline powder. The plastic material is composed of the following components by weight percentage: 75-85% polypropylene, 10-15% filler, 0.5-1.5% stabilizer, 2-4% white mineral oil, and 1-3% colorant. The mixed rare earth ionized material is composed of the following components by weight percentage: 3-5% antistatic agent, 2-5% tourmaline powder, and 0.5-1.5% mixed rare earth.

[0038] In practical implementation, the water ionization structure 1 can utilize the ionization function of the mixed rare earth ionization material to ionize water molecules. It can first ionize water molecules into small water molecule clusters, which can make the particle size after ultrasonic atomization smaller and more uniform. Furthermore, the mixed rare earth ionization material contains an antistatic agent, which can further prevent the charge generated after the ultrasonic atomization water molecules are broken down from losing negative charge due to the positive charge generated by the plastic parts, thereby effectively preventing the loss of negative oxygen ions.

[0039] The aforementioned water ionization structure 1 is placed in the atomization chamber, and the ultrasonic ceramic transducer is separated from the water level detection device 24 by the isolation chamber 13. Moreover, the top surface of the isolation chamber 13 is a sealed surface, that is, a sealed solid surface, so that the isolation chamber 13 forms a relatively sealed space, which can accommodate the water level detection device 24. This prevents the water splashed up when the ultrasonic transducer atomizes from falling onto the water level detection device 24, thereby effectively preventing water droplets from splashing onto the water level detection device 24 and causing false water detection, thus improving the water detection sensitivity. At the same time, since the water ionization structure 1 itself is made of plastic material mixed with mixed rare earth ionizing materials, it can ionize the water in the atomization chamber into small water molecule clusters, thereby enhancing the ionization effect in the atomization chamber, thus preparing for the fineness of atomization of the ultrasonic ceramic transducer.

[0040] In one embodiment, the top surface of the cover is also provided with a plurality of second through holes 12, the second through holes 12 being smaller than the first through holes 11.

[0041] The second through hole 12 can be a square hole, a round hole, or an irregular hole. A square hole can be a rectangular hole, a square hole, or a diamond hole. A round hole can also be an elliptical hole. An irregular hole can be an S-shaped hole or other irregular shapes.

[0042] When the ultrasonic transducer atomizes, it creates a tension height, causing water to splash up and form droplets. When these droplets fall and drip into the atomization chamber, they create noise. In the above embodiment, by opening multiple second through holes 12 on the top surface of the cover of the water ionization structure 1, the water droplets fall onto the perforated plane, which can reduce the noise of falling water. At the same time, when the water mist passes through the second through holes 12, it makes more full contact with the cover, which helps to improve the ionization efficiency.

[0043] In one embodiment, the isolation cavity 13 is composed of a baffle 131 disposed inside the enclosure, a portion of the top surface of the enclosure surrounded by the baffle 131, and a portion of the side surface of the enclosure; the baffle 131 is located between the ultrasonic ceramic transducer and the water level detection device 24.

[0044] Among them, the top surface and the side surface of the enclosure surrounded by the baffle 131 are sealed surfaces to completely separate the ultrasonic ceramic transducer from the water level detection device 24; the baffle 131 can be a flat plate or a curved plate.

[0045] In the above embodiments, the baffle 131 inside the cover can block water droplets splashed up when the atomizing plate is working, preventing water from splashing onto the water level detection device 24, thereby improving the water detection sensitivity; moreover, the formation of the isolation cavity 13 only requires setting the baffle 131 inside the cover, which is simple in structure and easy to manufacture.

[0046] In one embodiment, the baffle 131 is an arc-shaped plate, and the baffle 131 and the cover are integrally formed. The use of an arc-shaped plate as the baffle 131 in the above embodiment helps to reduce the space occupied by the isolation chamber 13, ensures that the ionized water mist has enough space to rise, and has a simple structure that is easy to manufacture.

[0047] Furthermore, the baffle 131 is an arc-shaped plate bent towards the direction of the ultrasonic ceramic transducer, which makes the structure more robust and ensures the stability of the water ionization structure 1.

[0048] In one embodiment, the atomizing chamber is provided with an air inlet 25; the cover is a cylindrical structure and the side facing the air inlet 25 is flat to leave installation space for the air inlet 25; the side wall of the cover includes several arc-shaped support parts supported on the bottom surface of the atomizing chamber, which is convenient for assembly.

[0049] The air inlet 25 is located at the upper part of the air inlet chamber, which is located on the lower side of the atomizing water tank 22, and an air inlet fan is provided at the bottom of the air inlet chamber.

[0050] In one embodiment, the water storage tank 21 is connected to the water inlet of the atomizing water tank 22; the bottom of the side wall of the cover facing the water inlet is provided with an arc-shaped opening 132, and the bottom sides of the baffle 131 are provided with opening grooves 133 to allow water to flow from the water storage tank 21 into the atomizing chamber.

[0051] In practice, the water in the water storage tank 21 flows into the atomizing chamber through the water inlet of the atomizing water tank 22, the arc-shaped opening 132 on the side wall of the cover, and the opening grooves 133 on both sides of the bottom of the baffle 131, and comes into contact with the ultrasonic ceramic transducer, forming water mist through ultrasonic vibration.

[0052] In another embodiment, the present invention provides a water negative oxygen ion generator 2, including a water ionization structure 1 as described in any of the above embodiments to improve water detection sensitivity. This structure can prevent water droplets from splashing onto the water level detection device 24, thereby improving water detection sensitivity. It can also ionize the water in the atomization chamber through the water ionization structure 1, thereby enhancing the ionization effect in the atomization chamber.

[0053] In the above embodiments, such as Figure 1-7As shown, the water negative oxygen ion generator 2 includes a water storage tank 21, an atomizing water tank 22, and a negative charge output device 23. The atomizing water tank 22 has an atomizing chamber, and the bottom of the atomizing chamber is equipped with an ultrasonic ceramic transducer and a water level detection device 24. The water storage tank 21 is connected to the atomizing water tank 22 to supply water to the atomizing chamber. The water is atomized into water mist by ultrasonic vibration. The water storage tank 21 and the atomizing water tank 22 are injection molded using plastic materials with added mixed rare earth ionizing materials. These materials are used to ionize water molecules and prevent the loss of negative charges generated by ultrasonic atomization due to electrostatic discharge. By directly adding the mixed rare earth ionizing materials to the plastic material, the water storage tank 21 and the atomizing water tank 22 themselves have ionization capabilities, resulting in smaller and more uniform water mist particles after ultrasonic atomization, and reducing the loss of negative charges, thereby preventing the loss of negative oxygen ions.

[0054] In one embodiment, such as Figure 8 As shown, the negative charge output device 23 includes a conical tube 231, a fan bracket 232, and a silent fan 233. The silent fan 233 is mounted on the fan bracket 232. The front end of the fan bracket 232 is provided with a needle holder into which the conical tube 231 can be inserted. A negative charge output needle is installed on the front end ring of the needle holder. The fan bracket 232 is fixedly connected to the rear end of the conical tube 231 so that the air outlet of the silent fan 233 is aligned with the opening at the rear end of the conical tube 231, and the negative charge output needle is located at the outlet position at the front end of the conical tube 231.

[0055] In the prior art, the negative charge output needle is located at the outlet of the tapered tube 231. However, in actual production, the narrow outlet of the tapered tube 231 makes installation difficult.

[0056] In the above embodiment, by setting a needle holder into which a tapered tube 231 can be inserted at the front end of the fan bracket 232, and then installing the negative charge output needle on the ring at the front end of the needle holder, the installation difficulty is simplified and production efficiency is improved.

[0057] In one embodiment, such as Figure 9 As shown, the top of the atomizing water tank 22 is symmetrically provided with two mist outlets 221. Each mist outlet 221 is detachably connected to a mist outlet pipe 222. The outlets of the two mist outlet pipes 222 are symmetrically located on both sides of the outlet of the conical pipe 231. The two mist outlet pipes 222 are connected as one unit by an arc-shaped mounting part 223. The arc-shaped mounting part 223 is provided with at least one mounting hole on each side of each mist outlet pipe 222. The two mist outlets 221 are provided with mounting seats that cooperate with the mounting holes on both sides. The two mist outlet pipes 222 are connected to the two mist outlets 221 through the arc-shaped mounting part 223.

[0058] Both mist outlets 221 are inclined forward, and each mist outlet 221 is detachably connected to a mist outlet pipe 222; the outlet of the mist outlet pipe 222 is close to the outlet of the conical pipe 231.

[0059] The above embodiment reduces the difficulty of injection molding manufacturing of the atomizing water tank 22 by using a mist outlet pipe 222 that is detachably connected to the mist outlet 221, and makes the assembly method of the atomizing water tank 22 more flexible. At the same time, by connecting the two mist outlet pipes 222 into a whole by the arc-shaped mounting part 223 and installing them together on the mist outlet 221, the accuracy of the installation position can be improved and the installation can be made simpler.

[0060] In the water negative oxygen ion generator 2 of the above embodiments, the negative charge output device 23 is installed above the atomizing water tank 22. The front end of the negative charge output device 23 is a conical tube 231, and a negative charge output needle is provided at the outlet of the conical tube 231. The rear end of the negative charge output device 23 is provided with a silent fan 233 for blowing the negative oxygen ions generated by ionization out of the conical tube 231. The top of the atomizing water tank 22 is provided with a mist outlet pipe 222. The inlet of the mist outlet pipe 222 is connected to the atomizing water tank 22, and the outlet of the mist outlet pipe 222 is close to the outlet of the conical tube 231. The lower side of the atomizing water tank 22 is provided with an air inlet chamber. The upper part of the air inlet chamber is provided with an air inlet 25, and the bottom of the air inlet chamber is provided with an air intake fan for blowing the water mist generated by ultrasonic atomization upward.

[0061] The negative charge output device 23 can ionize the air with negative high voltage to generate negative oxygen ions. In specific implementation, due to the weight and high density of water molecules after atomization, there is a certain charge loss at the outlet of the mist outlet 222, and the migration distance is shortened. Therefore, the negative charge output device 23 is set near the outlet of the mist outlet 222 to generate more negative charges. On the one hand, it can neutralize the number of positive ions at the outlet of the mist outlet 222, and on the other hand, it can make the water molecules at the outlet of the mist outlet 222 carry more negative charges, forming a high-concentration, small molecular cluster light ion effect at the mist outlet 221.

[0062] Furthermore, the atomizing water tank 22 may include a detachably connected upper shell and a lower shell. The air inlet cavity is located on one side of the lower shell and is integrally formed with it. The upper shell includes an annular inner wall and an outer wall. The height of the outer wall is lower than that of the inner wall, and the lower outer side of the outer wall is connected to the upper inner side of the lower shell. The lower end of the inner wall extends into the cavity of the lower shell. The side of the inner wall facing the air inlet cavity is recessed to fit the air inlet cavity, and the lower end of the recess is also provided with a notch to allow the airflow from the air inlet 25 to pass through. The ultrasonic ceramic transducer is located in the middle of the bottom of the lower shell, and the bottom of the side wall of the lower shell is provided with an inlet that communicates with the water storage tank 21.
