As shown in fig. 1, in some existing water ion emitting devices, the emitting head is generally a solid columnar structure, and the condensed water is mainly attached to the outer peripheral surface of the emitting head, which results in poor storage capacity of the emitting head for the condensed water. The comdenstion water flows away or breaks away from easily under vibrations state, perhaps when the condensing speed can not keep up with, leads to easily that the emitting head temporarily does not have the comdenstion water and can ionize, and then influences water ion emission device's purifying effect. Therefore, the present invention provides a water ion emitting device, which solves the above technical problems.

In one embodiment of the present invention, as shown in fig. 2 and 3, the water ion emitting device 10 includes a high voltage electrode 20, a water supply auxiliary member (e.g., a cooling member 30 in fig. 3, a water supply tank 70 in fig. 10), and an emitting head 40. The high voltage electrode 20 is used for providing a high voltage electric field, and specifically, the water ion emitting device 10 generally further includes a circuit board 50 (or a control board), and the high voltage electrode 20 is electrically connected to the circuit board 50 through a high voltage pack, so as to control the high voltage electrode 20 to generate a stable high voltage electric field. As shown in FIG. 2, the high voltage electrode 20 may be formed in a ring structure to provide a more uniform high voltage electric field, and the emitter head 40 may be disposed on the axis of the high voltage electrode 20. Of course, the high voltage electrode 20 may be configured to have a plurality of discharge ends according to actual needs, and is not limited in particular. In addition, in order to facilitate installation and fixation, the high voltage electrode 20 may further be provided with fixing holes, and the fixing holes may be distributed around the central axis of the high voltage electrode 20, so as to ensure balance and stability when the high voltage electrode 20 is installed.

The water source auxiliary member may be a refrigerating member 30, and is spaced from the high voltage electrode 20, and the refrigerating member 30 is mainly used for refrigerating the emitter 40, so that air around the emitter 40 can condense condensed water on the emitter 40, and further the condensed water is dissociated in a high voltage electric field to form water ions.

Alternatively, when the distance between the two second ends 43 of the emitter head 40 is sufficiently small, the water supply auxiliary member may be a water supply tank 70, and water to be ionized is stored in the water supply tank 70. The first end of the emitter head 40 is disposed adjacent to the high voltage electrode 20, and the two second ends 43 respectively protrude into the water supply tank 70, and the water in the water supply tank 70 is drawn to the first end 42 by capillary force and ionized under the high voltage electric field.

In this embodiment, the water source auxiliary device may be a refrigerating device 30, the refrigerating device 30 is mounted on a circuit board 50, and the circuit board 50 is spaced from the high voltage electrode 20. As shown in fig. 4, the cooling member 30 includes a first cooling plate 31 and a second cooling plate 32, and specifically, the first cooling plate 31 may be a P-type peltier element, and the second cooling plate 32 may be an N-type semiconductor peltier element. Of course, in other embodiments, the first cooling plate 31 and the second cooling plate 32 may also be P-type crystal grains and N-type crystal grains.

The first refrigeration piece 31 and the second refrigeration piece 32 are arranged at intervals and are respectively and electrically connected to the circuit board 50, and the first refrigeration piece 31 and the second refrigeration piece 32 are electrically connected by the transmitting head 40. When the power is supplied, the ends of the first and second cooling plates 31 and 32 electrically connected to the emitter head 40 are cooling ends 34, and the emitter head 40 is cooled. The ends of the first cooling plate 31 and the second cooling plate 32 electrically connected to the circuit board 50 are heat dissipation ends 33.

In this embodiment, in order to improve the storage capacity of the emitter 40 for the condensed water, as shown in fig. 4 or fig. 6, the emitter 40 includes two sections of emitter bars 41 arranged at an included angle, each section of the emitter bar 41 has a first end 42 and a second end 43 respectively, two the first end 42 is connected at an included angle and is close to the high voltage electrode 20, two the second end 43 is connected with the refrigeration piece 30 respectively, and the second end reaches the direction of the first end, the distance between the two sections of emitter bars is gradually reduced. The two sections of emission bars 41 arranged at an included angle may be formed by bending a complete emission bar 41, or may be formed by connecting two separate emission bars 41, for example, welding, gluing, etc. the first end 42 of the emission bar 41 at an included angle, or directly injecting the emission head 40 in a bent structure during manufacturing, which is not limited herein. The included angle between the two sections of the transmitting strips 41 can be set by adapting to the size of the distance between the first refrigerating sheet 31 and the second refrigerating sheet 32, but it should be noted that the included angle between the two sections of the transmitting strips 41 is not suggested to be set too large, so as to avoid failing to achieve the effect of improving the water storage capacity.

It can be understood that the two first ends 42 of the two sections of emitter bars 41 are connected at an included angle, that is, the closer the two sections of emitter bars 41 are to the first ends 42, the smaller the distance between the two corresponding positions is, the easier the capillary force is generated on the condensed water. After the emitter head 40 is cooled by the cooling member 30 and condensed water is condensed, the condensed water at the first end 42 can be attached to the emitter head 40 through a plurality of attachment surfaces in different directions, and also can be subjected to capillary force at an included angle, so that the condensed water is stably attached to the emitter head 40. Compared with the conventional structure in which the condensed water is attached to the outer circumferential surface of the emitter head 40 only by surface tension, the water ion emitter 10 of the present invention can better store the condensed water, avoiding a situation in which the condensed water is easily flowed or separated in a vibration state.

Furthermore, the emitter 40 may further include three, four or more emitter bars 41, the plurality of emitter bars 41 are circumferentially distributed around a central axis, and the plurality of first ends 42 of the plurality of emitter bars 41 are connected together in an included angle, so as to form a structure similar to an umbrella stand, thereby improving the storage capacity of the emitter 40 for the condensed water.

Of course, in addition to the two sections of the emitter bars 41 arranged at an included angle to improve the storage capacity of the emitter head 40 for the condensed water, a conical space 44 may be defined by the emitter head 40, and referring to fig. 3, 6 to 9, the conical space 44 is arranged in a tapered manner in a direction away from the second end 43. For example, the tapered space 44 may be conical, as shown in fig. 7, that is, the emitter head 40 may be made into a cone structure having an inner side surface 45 and an outer side surface 46, wherein the inner side surface 45 and the outer side surface 46 are conical surfaces, and the inner side surface 45 encloses the tapered space 44.

For another example, the conical space 44 may also be a triangular prism, as shown in fig. 9, that is, the emission head 40 may include two condensation sheets 48 disposed at an included angle, two ends of the condensation sheet 48 are the second end 43 and the first end 42, respectively, the two second ends 43 are connected to the refrigeration member 30, respectively, the two first ends 42 are connected at an included angle, that is, the first end 42 is located at a corner of the triangular prism.

Of course, the tapered space 44 may also be a triangular cone, a pentagonal cone, or other tapered structures, and the specific configuration may be set according to actual needs.

It should be noted that, when the emitter head 40 is in a cone structure, as shown in fig. 8, in order to enable the condensed water on the inner side surface 45 of the emitter head 40 to be ionized and output water ions, the first end 42 is further provided with an emitter 47, the emitter 47 is communicated with the inner side surface 45 and the outer side surface 46, and the electrolyzed water ions can be output through the emitter 47. The detailed position, number, shape, etc. of the emitting ports 47 are not particularly limited, for example, the emitting ports 47 may be formed at the top end of the emitting head 40, or may be formed on the side wall of the emitting head 40 near the first end 42.

It can be understood that, because the conical space 44 enclosed by the emitting head 40 is tapered in the direction away from the second end 43, that is, the first end 42 of the emitting head 40 has an included angle space, that is, the distance between two corresponding positions of the emitting head 40 and the conical space 44 is smaller, the closer to the first end 42, the smaller the distance between the two corresponding positions is, the easier the capillary force is to be generated on the condensed water. Therefore, it can be understood that after the emitter head 40 is cooled by the cooling member 30 and condensed water is condensed, the condensed water at the first end 42 can not only be attached to the emitter head 40 through a plurality of attachment surfaces in different directions, but also be subject to capillary force at the included angle space, so that the condensed water is stably attached to the emitter head 40. Compared with the conventional structure in which the condensed water is attached to the outer circumferential surface of the emitter head 40 only by surface tension, the water ion emitter 10 of the present invention can better store the condensed water, avoiding a situation in which the condensed water is easily flowed or separated in a vibration state.

In an embodiment, when the emitting head 40 includes two emitting bars 41 arranged at an included angle, the emitting bar 41 has an outer shape of any one of a straight bar shape and an arc bar shape, for example, the two emitting bars 41 are both straight bar shapes or both arc bar shapes, or one of the two emitting bars 41 is a straight bar shape and the other is an arc bar shape. The concrete can be selected according to the needs. When the emitting bars 41 are arc-shaped, as shown in fig. 5, each emitting bar 41 can be recessed toward one side where another emitting bar 41 is located, so that the gap between two emitting bars 41 is smaller, and the storage capacity of the emitter head 40 for the condensed water is further improved. Or the emission bar 41 may be recessed away from another emission bar 41, which is not specifically limited herein.

Similarly, when the emitter head 40 includes two angled condensation sheets 48, the condensation sheets 48 may be straight or curved (as shown in FIG. 5). When the emitter head 40 is of a cone configuration, its inside surface 45 may also be partially concave (as shown in FIG. 5).

In one embodiment, as shown in fig. 4, the water ion emitting device 10 further includes a circuit board 50, and the emitting head 40 is made of a conductive material. When the transmitting head 40 includes two sections of transmitting strips 41 arranged at an included angle, the second end 43 of one of the two sections of transmitting strips 41 is electrically connected to the first cooling plate 31, and the second end 43 of the other one is electrically connected to the second cooling plate 32. When the emitter head 40 includes two condensation sheets 48 arranged at an included angle or a cone structure, two corresponding positions on the second end 43 of the emitter head 40 may be selected to be respectively connected with the refrigeration member 30, or a pin may be arranged at the second end 43, and then connected with the refrigeration member 30 through the pin.

In one embodiment, as shown in fig. 4, the first cooling plate 31 and the second cooling plate 32 each have a heat dissipation end 33 and a cooling end 34 opposite to each other, and the cooling end 34 is electrically connected to the launching strip 41. The direction of the heat dissipation end 33 pointing to the cooling end 34 is parallel to the surface of the circuit board 50, that is, the first cooling plate 31 and the second cooling plate 32 are both horizontally installed on the circuit board 50. Compare in the vertical installation on circuit board 50 of refrigeration piece 30 among the prior art, the horizontal installation mode of first refrigeration piece 31 and second refrigeration piece 32 has increased the area of contact between first refrigeration piece 31 and second refrigeration piece 32 and the circuit board 50 in this application for first refrigeration piece 31 and second refrigeration piece 32 can comparatively stable settle on circuit board 50, reduce rocking of transmission head 40.

And the horizontal installation of the first and second cooling plates 31 and 32 also facilitates the fixing of the heat dissipation end 33 and the cooling end 34 of the first cooling plate 31 with the circuit board 50 and the emission head 40, respectively, and the fixing of the heat dissipation end 33 and the cooling end 34 of the second cooling plate 32 with the circuit board 50 and the emission head 40, respectively, thereby facilitating the installation of the whole cooling member 30.

Meanwhile, compared with the prior art that the transmitting head 40 is indirectly connected with the refrigerating end 34 of the refrigerating piece 30 through the conductive copper sheet, the transmitting head 40 is directly connected with the first refrigerating piece 31 and the refrigerating end 34 of the second refrigerating piece 32, so that the assembling steps between the transmitting head 40 and the refrigerating piece 30 are reduced, and the assembling efficiency of the whole water ion transmitting device 10 is higher.

In another embodiment, as shown in fig. 4, the cooling ends 34 of the first cooling plate 31 and the second cooling plate 32 are close to each other, and the heat dissipating ends 33 of the first cooling plate 31 and the second cooling plate 32 are far away from each other. So make between first refrigeration piece 31 and the second refrigeration piece 32 both only the refrigeration end 34 relatively be close to and other parts are comparatively dispersed, can be more convenient at this moment fix first refrigeration piece 31 and second refrigeration piece 32 on circuit board 50, also be convenient for set up corresponding circuit in order to switch on first refrigeration piece 31 and second refrigeration piece 32 at circuit board 50 simultaneously.

In addition, the arrangement can also enable the heat dissipation end 33 of the first cooling plate 31 and the heat dissipation end 33 of the second cooling plate 32 to be uniformly distributed around the center of the circuit board 50, so that the heat generated on the circuit board 50 by the heat dissipation end 33 of the first cooling plate 31 and the heat dissipation end 33 of the second cooling plate 32 is relatively uniform, and the possibility of damage caused by over-high local heating of the circuit board 50 is reduced.

In an embodiment, as shown in fig. 4 or 5, the circuit board 50 has a first board surface 51 and a second board surface 52 opposite to each other, the refrigeration member 30 is mounted on the first board surface 51, and when the emission head 40 includes two sections of emission bars 41 arranged at an included angle, the emission bars 41 penetrate through the circuit board 50 from a side where the second board surface 52 is located to be electrically connected with the refrigeration member 30, and at least a part of the emission bars is fixedly connected with the circuit board 50. That is to say, the emitter 40 is connected with the refrigeration element 30 through the second end 43 thereof, and is also fixedly connected with the circuit board 50 through other positions, so that the installation of the emitter 40 is more stable, the situation that the emitter 40 generates large shaking to cause the condensed water to flow away or break away from is avoided, and the storage capacity of the emitter 40 in the water ion emitting device 10 of the present invention for the condensed water is further improved.

When the emitter head 40 includes two condensation sheets 48 arranged at an included angle or is in a cone structure, the second end 43, the outer side wall surface and the like of the emitter head 40 can be fixedly connected with the circuit board 50, and therefore the installation stability of the whole emitter head 40 and the storage capacity of condensed water are improved.

In one embodiment, the water ion emitting device further includes a water guide 60, one end of the water guide 60 is disposed near the high voltage electrode 20, and the other end thereof is communicated with the water supply tank 70. For example, the water guide 60 may be a brush 60, a capillary tube, or the like, which guides water from the water supply tank 70 by capillary force.

In one embodiment, as shown in fig. 10, the water ion emitting device 10 further includes a brush member 60 and a water supply tank 70, wherein one end of the brush member 60 is disposed adjacent to the high voltage electrode 20, and the other end thereof is communicated with the water supply tank 70 through a water conduit, which may be a thinner conduit. It can be understood that, since the brushes of the brush member 60 are thin and the gap between the brushes is small, when the brushes are communicated with the water supply tank through the thin water introduction pipe, the water in the water supply tank 70 can be introduced to the ends of the brushes by capillary force and ionized into water ions under the high voltage electric field. It can be understood that the active water supply of the water ion emitting apparatus 10 can be realized by providing the brush member 60 and the water supply tank 70, and the problem that the condensing speed on the emitter head 40 cannot follow up to affect the purifying effect can be avoided. Of course, the brush member 60 may be separately used, so that the emitter head 40 and the cooling member 30 may not be provided, and the water ion emitting apparatus 10 may have a simpler structure and may be manufactured and assembled more easily.

In addition, a guide groove may be provided at the emitter head 40, through which the condensed water that is not electrolyzed is guided into the water supply tank 70, thereby realizing recycling of the condensed water.
