In an embodiment of the present invention, the water ion emitting end 11 includes a circuit board 111, a refrigeration component 113, and a discharge electrode 115; wherein, the definition circuit board 111 has a mounting surface 1111; the refrigeration assembly 113 is mounted on the mounting surface 1111, the refrigeration assembly 113 includes a first refrigeration sheet 1131 and a second refrigeration sheet 1133, the first refrigeration sheet 1131 and the second refrigeration sheet 1133 both have a heat dissipation end 1135 and a refrigeration end 1137 which are oppositely arranged, the heat dissipation end 1135 of the first refrigeration sheet 1131 and the heat dissipation end 1135 of the second refrigeration sheet 1133 are both electrically connected to the circuit board 111, the refrigeration end 1137 of the first refrigeration sheet 1131 is close to the refrigeration end 1137 of the second refrigeration sheet 1133, and the direction from the heat dissipation end 1135 of the first refrigeration sheet 1131 to the refrigeration end 1137 of the first refrigeration sheet 1131 and the direction from the heat dissipation end 1135 of the second refrigeration sheet 1133 to the refrigeration end 1137 of the second refrigeration sheet 1133 are both parallel to the mounting surface 1111; the discharge electrode 115 is disposed near the cooling end 1137 of the first cooling fin 1131 and the cooling end 1137 of the second cooling fin 1133, and is electrically connected to the cooling end 1137 of the first cooling fin 1131 and the cooling end 1137 of the second cooling fin 1133.

In an embodiment of the present invention, the circuit board 111 may be mainly used to conduct and control the operation of the first cooling plate 1131 and the second cooling plate 1133 in the cooling assembly 113. The projection of the circuit board 111 on the horizontal plane may be substantially square or rectangular, so that the shape of the circuit board 111 is regular and the circuit board is convenient for molding and manufacturing. Of course, in other embodiments, the projection of the circuit board 111 on the horizontal plane may also be a circle or other shapes, and the like, which is not limited in this application, and it is sufficient to mount and carry the refrigeration assembly 113. The material of the circuit board 111 may be ceramic, aluminum, or copper, and the corresponding circuit may be provided on the circuit board 111. The first and second cooling fins 1131 and 1133 of the cooling assembly 113 may be mainly used to cool the discharge electrode 115 after being powered on. The first cooling plate 1131 and the second cooling plate 1133 are a P-type peltier element and an N-type peltier element, respectively, and since the cooling principle of the P-type peltier element and the N-type peltier element after being energized is the prior art, the details thereof are not described herein. Of course, the present application is not limited thereto, and in other embodiments, the first cooling plate 1131 and the second cooling plate 1133 may also be P crystal grains and N crystal grains, respectively. In addition, the refrigeration assembly 113 may be provided with a group, and in this case, one end of the discharge electrode 115 is electrically connected to the refrigeration ends 1137 of the first refrigeration piece 1131 and the second refrigeration piece 1133 in the refrigeration assembly 113. Of course, two or more sets of the refrigeration assemblies 113 may also be provided, in this case, two or more sets of the refrigeration assemblies 113 are connected in parallel, and one end of the discharge electrode 115 is electrically connected to the refrigeration ends 1137 of the first refrigeration piece 1131 and the second refrigeration piece 1133 in each set of the refrigeration assembly 113. The discharge electrode 115 is mainly used to condense water vapor in the air into condensed water, and then discharge and ionize the condensed water to form water ions. Since the principle of the discharge electrode 115 ionizing the condensed water to form water ions is prior art, it is not described in detail herein. In addition, the discharge electrode 115 may be substantially provided in a needle shape to more easily discharge at a needle-shaped tip.

When the water ion emitting end 11 of the technical scheme of the invention works, the circuit board 111 can control the first refrigeration piece 1131 and the second refrigeration piece 1133 of the refrigeration component 113 to be conducted, so that the first refrigeration piece 1131 and the second refrigeration piece 1133 radiate heat through the respective radiating end 1135 and refrigerate through the respective refrigeration end 1137. And the discharge electrode 115 is disposed near the cooling ends 1137 of the first cooling fin 1131 and the second cooling fin 1133, so that the discharge electrode 115 can be cooled to a relatively low temperature, at which time the water vapor in the air condenses out condensed water on the discharge electrode 115. Then, when a high-voltage electric field is applied to the discharge electrode 115, the discharge electrode 115 can be driven to discharge, and condensed water condensed on the discharge electrode 115 is ionized into water ions, so that the generation of the water ions is realized.

In addition, in the scheme, the direction from the heat dissipation end 1135 of the first refrigeration piece 1131 to the refrigeration end 1137 of the first refrigeration piece 1131 and the direction from the heat dissipation end 1135 of the second refrigeration piece 1133 to the refrigeration end 1137 of the second refrigeration piece 1133 of the water ion emission end 11 are both parallel to the mounting surface 1111 of the circuit board 111, that is, the first refrigeration piece 1131 and the second refrigeration piece 1133 are horizontally mounted. Compared with the refrigeration assembly 113 vertically mounted on the circuit board 111 in the prior art, the contact area between the first refrigeration piece 1131 and the circuit board 111 is increased by the mounting manner of the first refrigeration piece 1131 and the second refrigeration piece 1133 in the present application, so that the first refrigeration piece 1131 and the second refrigeration piece 1133 can be stably mounted on the circuit board 111, at this time, the heat dissipation end 1135 and the refrigeration end 1137 of the first refrigeration piece 1131 are respectively fixed to the circuit board 111 and the discharge electrode 115, and the heat dissipation end 1135 and the refrigeration end 1137 of the second refrigeration piece 1133 are respectively fixed to the circuit board 111 and the discharge electrode 115, thereby facilitating the mounting of the first refrigeration piece 1131 and the second refrigeration piece 1133. Meanwhile, the discharge electrode 115 of the water ion emitting end 11 in the scheme is directly connected with the refrigeration ends 1137 of the first refrigeration piece 1131 and the second refrigeration piece 1133, compared with the case that the discharge electrode 115 of the water ion emitting end 11 in the prior art is indirectly connected with the refrigeration end 1137 of the refrigeration component 113 through a conductive copper sheet, the water ion emitting end 11 in the scheme can reduce the assembly steps and enable the discharge electrode 115 to be assembled more easily. Therefore, the structural arrangement of the water ion emitting terminal 11 in the present scheme simplifies the assembly process of the water ion emitting terminal 11, thereby improving the production efficiency of the water ion emitting terminal 11.

Referring to fig. 5, in an embodiment of the present invention, the cooling end 1137 of the first cooling fin 1131 and the cooling end 1137 of the second cooling fin 1133 are disposed opposite to each other, and the discharge electrode 115 is electrically connected to one end of the first cooling fin 1131 and one end of the second cooling fin 1133, which are located between the cooling end 1137 of the first cooling fin 1131 and the cooling end 1137 of the second cooling fin 1133.

It can be understood that the refrigeration end 1137 of the first refrigeration piece 1131 and the refrigeration end 1137 of the second refrigeration piece 1133 are disposed oppositely, that is, the first refrigeration piece 1131 and the second refrigeration piece 1133 are distributed on the mounting surface 1111 in a substantially "straight" shape, so that only the refrigeration end 1137 of the first refrigeration piece 1131 and the second refrigeration piece 1133 is relatively close to each other, and other portions are relatively dispersed, at this time, the first refrigeration piece 1131, the second refrigeration piece 1133 and the circuit board 111 can be more conveniently fixed, and meanwhile, it is also convenient to provide a corresponding circuit on the circuit board 111 to conduct the first refrigeration piece 1131 and the second refrigeration piece 1133. Moreover, the arrangement can also make the heat dissipation end 1135 of the first cooling fin 1131 and the heat dissipation end 1135 of the second cooling fin 1133 evenly distributed around the center of the circuit board 111, so that the heat generated on the circuit board 111 by the heat dissipation end 1135 of the first cooling fin 1131 and the heat dissipation end 1135 of the second cooling fin 1133 is relatively even, and the possibility of damage caused by over-high local heating of the circuit board 111 is reduced. And one end of the discharge electrode 115 is electrically connected to the first chilling plate 1131 and the second chilling plate 1133 is located between the chilling end 1137 of the first chilling plate 1131 and the chilling end 1137 of the second chilling plate 1133, so that the discharge electrode 115 and the chilling ends 1137 of the first chilling plate 1131 and the second chilling plate 1133 are both relatively close to each other, the cooling effect of the first chilling plate 1131 and the second chilling plate 1133 on the discharge electrode 115 is improved, and meanwhile, the connection structure is convenient to be arranged so as to conduct the discharge electrode 115 and the first chilling plate 1131 and the second chilling plate 1133. Certainly, it should be noted that the present application is not limited to this, in other embodiments, the refrigeration end 1137 of the first refrigeration piece 1131 and the second refrigeration piece 1133 may also be disposed in parallel or have a certain included angle, so as to ensure that the refrigeration end 1137 of the first refrigeration piece 1131 and the second refrigeration piece 1133 is relatively close to each other and the heat dissipation end 1135 is relatively far away from each other.

Referring to fig. 5 and fig. 7 in combination, in an embodiment of the present invention, the discharge electrode 115 includes a connection segment 1151 and a discharge segment 1153, wherein the connection segment 1151 is electrically connected to the cooling end 1137 of the first cooling fin 1131 and the cooling end 1137 of the second cooling fin 1133; the discharge segment body 1153 is connected to the connection segment body 1151, and the cross-sectional area of the discharge segment body 1153 is smaller than that of the connection segment body 1151.

It can be understood that the discharge electrode 115 is connected to the cooling end 1137 of the first cooling fin 1131 and the cooling end 1137 of the second cooling fin 1133 through the connecting segment 1151 having a relatively large cross-sectional area, which can facilitate the arrangement of a connecting structure for fixing the two cooling fins, thereby further improving the convenience of assembling the discharge electrode 115. The discharge electrode 115 condenses the water vapor in the air into condensed water through the discharge segment 1153 with a relatively small cross-sectional area and ionizes the condensed water, so that a good point discharge effect can be ensured. The projections of the connection segment 1151 and the discharge segment 1153 on the mounting surface 1111 may be circular, so that the side circumferential surfaces of the connection segment and the discharge segment have consistency to ensure uniformity of ionization effect. In addition, the present invention is not limited to this, and in other embodiments, the discharge electrode 115 may have a cylindrical shape with a uniform cross-sectional area at each location.

Referring to fig. 5, fig. 6 and fig. 7, in an embodiment of the present invention, the circuit board 111 has an upper surface and a lower surface that are oppositely disposed, and the upper surface of the circuit board 111 or the lower surface of the circuit board 111 is formed as a mounting surface 1111; when the upper surface of the circuit board 111 is formed as the mounting surface 1111, the first cooling plate 1131, the second cooling plate 1133, the connecting section body 1151 and the discharging section body 1153 are all located on the upper surface of the circuit board 111; when the lower surface of the circuit board 111 is formed as the mounting surface 1111, the first cooling plate 1131, the second cooling plate 1133 and the connection segment 1151 are located on the lower surface of the circuit board 111, and the discharge segment 1153 passes through the circuit board 111 and is located on the upper surface of the circuit board 111.

It can be understood that, when the upper surface of the circuit board 111 is formed as the mounting surface 1111, the first cooling plate 1131, the second cooling plate 1133, the connecting segment 1151 and the discharging segment 1153 are located on the same side of the circuit board 111, so that the first cooling plate 1131, the second cooling plate 1133, the connecting segment 1151 and the discharging segment 1153 can be quickly fixed to each other. When the lower surface of the circuit board 111 is formed as the mounting surface 1111, the connection segment 1151 and the discharge segment 1153 of the discharge electrode 115 are located on different sides of the circuit board 111, and the discharge electrode 115 is limited by the contact between the connection segment 1151 and the lower surface of the circuit board 111, so that the mounting stability of the discharge electrode 115 can be improved. At this time, the circuit board 111 is provided with an over-yielding hole 1113 for the discharge segment body 1153 to pass through, and the aperture of the over-yielding hole 1113 may be slightly smaller than the cross section of the connection segment body 1151 and slightly larger than the cross section of the connection segment body 1151, so that the connection segment body 1151 is abutted and limited against the lower surface of the circuit board 111.

In an embodiment of the present invention, the connecting segment 1151 is welded to the cooling end 1137 of the first cooling plate 1131 and the cooling end 1137 of the second cooling plate 1133.

It can be understood that the connecting segment body 1151 is welded and fixed to the first cooling fin 1131 and the second cooling fin 1133, so that the discharge electrode 115 can be mechanically connected to the first cooling fin 1131 and the second cooling fin 1133, and the discharge electrode 115 can be electrically conducted to the first cooling fin 1131 and the second cooling fin 1133. This simplifies the connection structure between the connection segment body 1151 and the first and second cooling fins 1131 and 1133, thereby reducing the manufacturing cost of the water ion emitting terminal 11. Meanwhile, the welding fixation also has the advantages of stability and reliability, so that the connection stability of the connecting section body 1151 and the first refrigeration piece 1131 and the second refrigeration piece 1133 can be ensured. Of course, the present application is not limited thereto, and in other embodiments, the connecting segment 1151 and the cooling end 1137 of the first cooling plate 1131 and the cooling end 1137 of the second cooling plate 1133 may be fixed by conductive adhesive or may be fixed by inserting (i.e. by matching of a protrusion and a groove).

In an embodiment of the invention, the heat dissipating end 1135 of the first cooling plate 1131 and the heat dissipating end 1135 of the second cooling plate 1133 are fixed to the circuit board 111 by soldering.

It can be understood that the heat dissipation end 1135 of the first cooling fin 1131 and the heat dissipation end 1135 of the second cooling fin 1133 are fixed to the circuit board 111 by welding, so that the first cooling fin 1131 and the second cooling fin 1133 can be mechanically connected to the circuit board 111, and the first cooling fin 1131 and the second cooling fin 1133 can be electrically conducted to the circuit board 111. This simplifies the implementation of the connection structure between the first and second cooling fins 1131, 1133 and the circuit board 111, thereby further reducing the manufacturing cost of the water ion emitting terminal 11. Meanwhile, the welding fixation also has the advantages of stability and reliability, so that the connection stability of the first cooling plate 1131 and the second cooling plate 1133 with the circuit board 111 can be ensured. Of course, the present application is not limited thereto, and in other embodiments, the first cooling plate 1131 and the second cooling plate 1133 may be fixed to the circuit board 111 by a conductive adhesive, or may be fixed to the circuit board by plugging (i.e. by the cooperation of the protrusion and the groove).

Referring to fig. 1, fig. 2, fig. 3 and fig. 4, the present invention further provides a water ion emitting apparatus 10, where the water ion emitting apparatus 10 includes a water ion emitting end 11 and a high voltage electrode 13, and the specific structure of the water ion emitting end 11 refers to the above embodiments, and since the water ion emitting apparatus 10 adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and are not repeated herein. The high voltage electrode 13 is disposed opposite to one end of the discharge electrode 115 away from the first cooling fin 1131 and the second cooling fin 1133. That is, the discharge electrode 115 can be stably driven to discharge by applying a high voltage to the high voltage electrode 13. The high voltage electrode 13 can be electrically connected to the circuit board 111, so as to conduct and control the high voltage electrode 13 through the circuit board 111. And the shape of the high voltage electrode 13 may be substantially ring-shaped.

In an embodiment of the present invention, the water ion emitting device 10 further includes a box body 15; the circuit board 111 and the refrigeration component 113 are both arranged in the box body 15, and one end of the discharge electrode 115, which is far away from the first refrigeration piece 1131 and the second refrigeration piece 1133, penetrates through the box body 15 and is exposed to the outside of the box body 15; the high voltage electrode 13 is provided on the outer surface of the case 15.

It can be understood that the box 15 can protect the circuit board 111 and the cooling module 113 to a certain extent, so as to reduce the possibility of damage to the circuit board 111 and the cooling module 113 by foreign objects, thereby being beneficial to prolonging the service life of the circuit board 111 and the cooling module 113.

Referring to fig. 1 and 2, in an embodiment of the present invention, the outer surface of the box 15, on which the high voltage electrode 13 is disposed, is provided with a water tank 1531 for accommodating a portion of the condensed water condensed by the discharge electrode 115.

It can be understood that when the condensed water on the discharge electrode 115 reaches a certain amount, the condensed water can flow into the water tank 1531 to be accommodated, so that a certain distance is provided between the bubble formed by ionization of the condensed water and the high voltage electrode 13, and the negative product generated during ionization due to too small distance between the bubble and the high voltage electrode is avoided, thereby improving the ionization effect of the discharge electrode 115 on the condensed water. In order to improve the evaporation of the condensed water flowing into the water tank 1531, the water tank 1531 may include a plurality of first sub-water tanks 1533, each of the first sub-water tanks 1533 is extended from the center of the case body 15 to the edge, and the plurality of first sub-water tanks 1533 are uniformly distributed around the center of the case body 15. Further, the water tank 1531 may further include a plurality of second sub-water tanks 1535, each of the plurality of second sub-water tanks 1535 is disposed around the center of the box body 15 in a ring shape, and diameters of the plurality of second sub-water tanks are sequentially increased from the center to the edge of the box body 15, and the second sub-water tanks 1535 are communicated with the first sub-water tanks 1533. Thus, the excessive condensed water on the discharge electrode 115 can flow on the surface of the case 15 by the guiding function of the first and second sub-water tanks 1533 and 1535, and thus has a large evaporation area.

Referring to fig. 2, fig. 3 and fig. 4, in an embodiment of the invention, a baffle 1513 is protruded from an inner surface of the box body 15 facing the mounting surface 1111, an end of the baffle 1513 away from the box body 15 abuts against the mounting surface 1111, and the baffle 1513 is disposed around the refrigeration assembly 113 and the discharge electrode 115.

It can be understood that the arrangement of the coaming 1513 can enclose the refrigeration component 113 and the discharge electrode 115, i.e. isolate the refrigeration area from the heat dissipation area, so as to prevent the air flow in the refrigeration area and the heat dissipation area from forming convection, thereby ensuring the refrigeration effect of the refrigeration area.

In an embodiment of the present invention, the box body 15 includes a box body 151 and a box cover 153, the box body 151 is provided with a containing groove 1511; the box cover 153 is detachably connected to the box body 151 and covers the notch of the accommodating groove 1511; the circuit board 111 and the refrigeration assembly 113 are arranged in the accommodating groove 1511; one end of the discharge electrode 115, which is far away from the first refrigeration piece 1131 and the second refrigeration piece 1133, penetrates through the box cover 153; the high voltage electrode 13 is provided on the surface of the cartridge face cover 153 facing away from the cartridge body 151.

It can be understood that the box cover 153 is detachably connected to the box body 151, so that the box cover 153 can be detached from the box body 151 when the refrigeration assembly 113 or the discharge electrode 115 in the accommodating groove 1511 is damaged, thereby facilitating the repair and replacement of the refrigeration assembly 113 or the discharge electrode 115. The box cover 153 may be fixed to the box body 151 by screws, snaps, or magnetic attraction, so as to simplify the assembly and disassembly process of the box cover 153. The surrounding plate 1513 may be a bottom wall of the receiving groove 1511, and may be integrally formed with the cartridge body 151. The circuit board 111 can be clamped and fixed by the box body 151 and the box surface cover 153 in a matching manner, so that the circuit board 111 is not required to be limited and fixed by an additional connecting structure, and meanwhile, the assembling process among the circuit board 111 can be simplified by the arrangement. Further, in order to improve the heat dissipation effect of the circuit board 111 located in the receiving groove 1511, the bottom wall and/or the side wall of the box body 151 may be provided with an airflow opening 1515 communicating with the receiving groove 1511. In addition, the high voltage electrode 13 may be supported and fixed by a supporting post 1537 protruding from the surface of the case cover 153 facing away from the case body 151.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
