[0027] As can be fully understood by those skilled in the art, the features of different embodiments of the present disclosure may be partially or fully coupled or combined with each other, and may cooperate with each other in various ways and be technically driven. The embodiments of the present disclosure may be executed independently of each other, or may be executed together in a mutually dependent relationship.

[0028] Referring to Figures 1 to 4 , the present utility model discloses an adjustable negative ion generator, which includes a main body 1 and a negative ion generating end 2. A plurality of negative ion generating needles 3 for generating negative ions are provided in the negative ion generating end 2, and the negative ion generating needles 3 are connected through a power line to a circuit structure in the main body 1. The negative ion generating end 2 is connected to the main body 1 through an angle adjusting mechanism, so as to realize the angle adjustment of the negative ion generating end 2.

[0029] As shown in the figure, the angle adjustment mechanism includes a guiding groove 4 provided on the main body 1 and a guiding rod 5 provided on the negative ion generating end 2. The guiding rod 5 can slide in the guiding groove 4 but cannot escape from the guiding groove 4. A locking structure for the negative ion generating end 2 is provided between the negative ion generating end 2 and the main body 1. Through the above structure, the angle of the negative ion generating end 2 can be adjusted and the angle can be maintained. As a further specific structure, the locking structure includes a first tooth 6 provided on the negative ion generating end 2 and a second tooth 7 provided on the main body 1. The first tooth 6 can be engaged into the tooth grooves between different second teeth 7. Since the first tooth 6 and the second tooth 7 will not slide relative to each other after being engaged, the adjusted angle is maintained. Of course, the above structure can satisfy the planar angle adjustment of the negative ion generating end 2 along the guiding groove 4. As a further structure: an adjusting plate 8 is provided on the guiding rod 5. The second tooth 7 is provided on the bottom surface of the end face of the main body 1. The first tooth 6 is provided on the adjusting plate 8. The second tooth 7 and the main body 1 are formed by injection molding, and the adjusting plate 8 and the first tooth 6 are injection molded. Preferably, the guiding rod 5 is a screw rod. A through hole 9 is provided on the adjusting plate 8. The guiding rod 5 passes through the through hole 9 and the guiding groove 4 and is threadedly connected to the negative ion generating end 2. The above structure is convenient for controlling the distance between the adjusting plate 8 and the bottom surface of the end face of the main body 1, so as to control the engagement tightness between the first tooth 6 and the second tooth 7. By tightening the screw rod, the nut presses the adjusting plate 8 to achieve tightness control. Of course, both the first tooth 6 and the second tooth 7 are arc-shaped teeth and are continuously arranged in a wavy shape, which is convenient for the first tooth 6 to be engaged into the tooth grooves between different second teeth 7 by extrusion. Of course, the tooth grooves are also arc-shaped grooves.

[0030] As a further structure, guide plates 10 are oppositely provided on the adjusting plate 8, and a sliding groove 11 is provided on the bottom surface of the end face of the main body 1. The guide plates 10 are slidably engaged with the sliding groove 11, so that the adjusting plate 8 will not rotate when moving.

[0031] As shown in the figure, the end face of the main body 1 is a semi-circular groove, and the bottom surface of the negative ion generating end 2 is a semi-circular shell corresponding to the semi-circular groove. Therefore, the guiding groove 4 is semi-circular. Of course, the surface of the adjusting plate 8 in contact with the main body 1 is an arc surface. When the negative ion generating end 2 is adjusted, it can rotate along the semi-circle, so as to achieve angle adjustment. For the convenience of manufacturing and installation, the main body 1 includes a cylindrical shell 12 and a top cover 13 for closing the port of the cylindrical shell 12. An annular slot 14 is provided on the top cover 13. The edge of the port of the cylindrical shell 12 can be inserted into the slot 14 and fixed by screws. The end face of the main body 1 is the surface of the top cover 13. Therefore, the second tooth 7 is provided on the bottom surface of the top cover 13. During assembly, the negative ion generating end 2 and the top cover 13 can be assembled first, and then plugged and fixed with the cylindrical shell 12.

[0032] As shown in the figure, limiting grooves 15 are oppositely arranged on the end surface of the main body 1, and limiting rods 16 inserted into the limiting grooves 15 are arranged on the bottom surface of the negative ion generating end 2. The limiting grooves 15 are parallel to the guiding grooves 4. Through the above structure, the rotation of the end surface of the main body 1 is limited, avoiding the separation of the first gear 6 from the second gear 7 and the torsional desoldering of the power line. A wire passing groove 17 is arranged on the end surface of the main body 1. The power line can move in the wire passing groove 17 when passing through the wire passing groove 17, so that it is not necessary to make the power line very long to leave enough amount for moving and stretching, thus saving wire materials.

[0033] The above has introduced in detail an adjustable negative ion generator provided by an embodiment of the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
