Compared with the method in which the air intake pipe is directly connected to the air excitation hole in my previous patent, this application adds the structure of the air storage chamber, so that high-pressure air is gathered here, and then through the air excitation hole 1404, it impacts the baffle 1406 outwards. Scattering the rebounding gas at the baffle and the impact action produces a large amount of negative oxygen ions, and the impact effect is more obvious. Experiments have found that the negative oxygen ion generator using this scheme produces more than 4 times the number of negative oxygen ions in the applicant’s prior patent.

The baffle 1406 may also be integrally formed with the bottom plate. The baffle can be a segmented structure, and it is sufficient to ensure that there is a baffle at the position facing the gas stimulation hole 1404.

2. The side wall of the container body 1202 is provided with a hook 1202a.

3. A suction cup support base 15A is used instead of the humidifier support base 15 of the first embodiment.

Using the solution of embodiment 2, compared to embodiment 1, the gas is not impacted downward, but horizontally. The gas will not be affected by buoyancy too much in the impact direction, so that the impact force when reaching the baffle is greater, resulting in More negative oxygen ions. In addition, the gas stimulation holes are distributed in a ring shape. Under the same container cross-sectional area, more negative oxygen ions are generated, which saves the volume of the container.

Example 3

Referring to Figures 6 and 7, compared with Embodiment 1, the air supply part, namely the housing 5 and the parts inside it are the same, the difference is that the upper spray negative oxygen ion generator 14 is used to replace the embodiment 1 Down spray type negative oxygen ion generator 14.

The bottom plate of the upper spray type negative oxygen ion generator 14 is composed of all or part of the bottom 1205 of the container body 1202 (the bottom of the container body 1202 in FIG. 6 constitutes the bottom plate of the negative oxygen ion generator 14), and the side plate is composed of Part of the side wall 1204 of the container body 1202 is formed. The top plate 1401 is fixed above the bottom plate. It can be fixed to the side wall of the container body 1202 or the bottom of the container body 1202 (in the case where the bottom part of the container constitutes the bottom plate, The gas storage chamber occupies a part of the bottom of the container body). A baffle 1406 is provided above the top plate 1401. In this embodiment, the air inlet pipe 1203 of the air storage chamber can be arranged outside the container body 1202 or inside the container body 1202 (when the air storage chamber only occupies a part of the bottom of the container body)

An air excitation hole 1404 is provided on the top plate, and preferably, the baffle 1406 is arranged 5-15 mm above the air excitation hole 1404. The shape of the baffle is not limited to a circle or a square. The shape of the baffle is cross in FIG.

Preferably, the air inlet of the top-spray negative oxygen ion generator 14 is provided on the side wall of the container body 1202, and the air outlet pipe 10 connected to the air inlet is provided with a one-way valve 16 to prevent the liquid 13 from flowing back and out The air port is connected to the universal tube 17, and the universal tube 17 can be bent to any position at will and kept in this position. There are ready-made commodities to buy, which can be conveniently aimed at the mouth and nose of a person to blow.

With the solution of this embodiment, the structure of the air storage chamber makes full use of the structure of the container body, making the overall structure simpler and reducing the manufacturing cost. Moreover, the baffle is arranged above, so that the gas will not be hindered by buoyancy, but can accelerate the gas. More negative oxygen ions are produced.

Example 4

Referring to FIGS. 8 and 9, compared with Embodiment 3, only the internal spray type negative oxygen ion generator 14 is used instead of the top spray type negative oxygen ion generator 14 of the embodiment 3. Other aspects are basically the same as the embodiment 3. The gas storage chamber 1400 of the internal spray type negative oxygen ion generator 14 is located outside the container body 1202. It has an annular structure and includes a top plate 1401, a bottom plate 1403, an inner plate and an outer plate 1402, wherein the side walls of the container body 1202 A part constitutes the inner side plate of the air storage chamber, and the gas stimulation hole 1404 is formed on the inner side plate of the air storage chamber 1400. The baffle 1406 is disposed in the liquid in the container, and is opposite to the gas stimulation hole.

The air inlet is preferably arranged on the outer plate 1402 of the air storage chamber 1400. The air inlet may also be arranged on the top plate 1401 or the bottom plate 1403 of the air storage chamber 1400. Of course, there may also be multiple air inlets, which are arranged at different positions of the air storage chamber.
