Description

Technical Field

[0001] The utility model relates to the technical field of negative ions, in particular to a negative ion emission end. Background Art

[0002] As an important part of the air purification device, the negative ion emitter is mainly used to release negative ions. Since most negative ion emitters are small in size, they can be more flexibly integrated into the air purification systems of various products, for example, in the air purification system of a car.

[0003] The existing negative ion emitting end mostly includes a shell, a high-voltage wire harness with an emitting unit, and a grounding wire harness with an emitting unit. The high-voltage wire harness and the grounding wire harness are arranged inside the shell, and both emitting units can pass through the shell. To facilitate the assembly of the negative ion emitting end, the shell is composed of an upper shell and a lower shell. After the high-voltage wire harness and the grounding wire harness are placed in the lower shell, the upper shell and the lower shell are snapped together to complete the assembly of the negative ion emitting end. In addition, in order to ensure the sealing of the negative ion emitting end, the negative ion emitting end often needs to be coated with glue on the periphery of the shell after assembly.

[0004] However, since a certain distance needs to be kept between the high-voltage wire harness and the grounding wire harness during assembly to avoid electromagnetic mutual influence between the two, in order to reduce the occupied area of ​​the negative ion emitting end, the high-voltage wire harness and the grounding wire harness are often assembled into a bundle at one end away from the emitting unit when connected to the remaining components of the negative ion generator, which causes the high-voltage wire harness and the grounding wire harness to be easily deformed inside the shell. Since the high-voltage wire harness and the grounding wire harness are both elastic, when the upper shell is buckled with the lower shell, it is necessary to control the high-voltage wire harness and the grounding wire harness manually or through some other fixing mechanisms such as grippers to avoid the high-voltage wire harness and the grounding wire harness from being offset under the action of their own elasticity. This process not only increases the assembly time of the entire negative ion emitting end, but also easily damages the emitting unit, the high-voltage wire harness and the grounding wire harness. What's more, under the resetting action of the high-voltage wire harness and the grounding wire harness, a gap may be generated between the upper shell and the lower shell that have been buckled, which easily causes the rubber to enter the interior of the shell during the rubber encapsulation process, thereby causing damage to the negative ion emitting end.

[0005] Therefore, the above problems need to be solved urgently. Utility Model Content

[0045] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0047] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0048] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] When assembling the high-voltage wire harness and the grounding wire harness, a certain distance needs to be kept between the two to avoid electromagnetic mutual influence between the two. However, in order to reduce the occupied area of ​​the negative ion emitting end, when the high-voltage wire harness and the grounding wire harness are connected to the remaining components of the negative ion generator, the high-voltage wire harness and the grounding wire harness are often assembled into a bundle at one end away from the emitting unit. Since the high-voltage wire harness and the grounding wire harness are both elastic, they are easily deformed inside the shell, thereby reducing the assembly efficiency of the negative ion emitting end. For this reason, in this embodiment, the structure of the negative ion emitting end is changed so that the high-voltage wire harness and the grounding wire harness can be limited to avoid unnecessary influence during the assembly process, thereby improving the sealing of the negative ion emitting end.

[0050] Specifically, see Figures 1 to 6The negative ion emitting end 200 includes an upper shell 1, a lower shell 2, a high-voltage wire harness 3, a grounding wire harness 4, a high-voltage protective sleeve 5 and a grounding protective sleeve 6. The upper shell 1 and the lower shell 2 can be assembled to form an accommodating space to accommodate the high-voltage wire harness 3 and the grounding wire harness 4. The high-voltage protective sleeve 5 is sleeved on the high-voltage wire harness 3, and the grounding protective sleeve 6 is sleeved on the grounding wire harness 4; a first limiting portion 7 is arranged in the accommodating space, and the first limiting portion 7 has a first through hole and a second through hole through which the high-voltage wire harness 3 and the grounding wire harness 4 are respectively penetrated; along the penetration direction of the high-voltage wire harness 3, a second limiting portion 8 is also arranged in the accommodating space, the second limiting portion 8 is located on the upstream side of the first through hole, and the high-voltage protective sleeve 5 is clamped between the first limiting portion 7 and the second limiting portion 8; along the penetration direction of the grounding wire harness 4, a third limiting portion 9 is also arranged in the accommodating space, the third limiting portion 9 is located on the upstream side of the second through hole, and the grounding protective sleeve 6 is clamped between the first limiting portion 7 and the third limiting portion 9.

[0051] In actual application, when assembling the negative ion emitting end 200, the high-voltage wire harness 3 and the grounding wire harness 4 are respectively arranged in the first through hole and the second through hole, so as to limit the up and down movement of the high-voltage wire harness 3 and the grounding wire harness 4, and then the high-voltage protective sleeve 5 is clamped between the first limiting portion 7 and the second limiting portion 8, and the grounding protective sleeve 6 is clamped between the first limiting portion 7 and the third limiting portion 9, so as to limit the horizontal movement of the high-voltage wire harness 3 and the grounding wire harness 4. In this way, the high-voltage wire harness 3 and the grounding wire harness 4 can be locked, thereby improving the assembly efficiency of the negative ion emitting end 200.

[0052] In addition, under the action of the first limiting portion 7, the second limiting portion 8 and the third limiting portion 9, the high-voltage wire harness 3 and the grounding wire harness 4 can be locked, thereby avoiding the generation of a gap between the upper shell 1 and the lower shell 2 during the rubber coating process, thereby ensuring the sealing quality.

[0053] In this embodiment, the first position-limiting portion 7 includes two first profiling grooves 71 disposed on the upper shell 1 and two second profiling grooves 72 disposed on the lower shell 2, and the two first profiling grooves 71 can respectively surround the first through hole and the second through hole with the two second profiling grooves 72. In practical applications, before assembly, the high-voltage wire harness 3 and the grounding wire harness 4 are respectively placed in the two first profiling grooves 71, and then in the process of the lower shell 2 and the upper shell 1 being buckled together, the first profiling groove 71 and the second profiling groove 72 can surround the first through hole and the second through hole, thereby completing the locking of the high-voltage wire harness 3 and the grounding wire harness 4.

[0054] The first limiting portion 7 further includes a first convex ring 73 and a second convex ring 74, the first convex ring 73 and the second convex ring 74 are coaxially arranged with the first through hole and the second through hole, respectively, and the high-voltage protective sleeve 5 is clamped between the first convex ring 73 and the second limiting portion 8, and the grounding protective sleeve 6 is clamped between the second convex ring 74 and the third limiting portion 9. It can be understood that before assembly, the high-voltage wire harness 3 and the grounding wire harness 4 are respectively inserted between the first convex ring 73 and the second convex ring 74, so that the high-voltage wire harness 3 and the grounding wire harness 4 can be preliminarily positioned, and then the high-voltage wire harness 3 and the grounding wire harness 4 can be locked under the action of the first profiling groove 71 and the second profiling groove 72.

[0055] The accommodation space is also provided with a first wire groove 10 for accommodating the high-voltage wire harness 3 and the grounding wire harness 4, and the first wire groove 10 is arranged on the side away from the first limiting portion 7; the second limiting portion 8 has a second wire groove 81 for accommodating the high-voltage wire harness 3, and the second wire groove 81 is connected to the first wire groove 10; the third limiting portion 9 has a third wire groove 91 for accommodating the grounding wire harness 4, and the third wire groove 91 is connected to the first wire groove 10. It can be understood that the high-voltage wire harness 3 and the grounding wire harness 4 are a bundle of main lines outside the negative ion emission end 200, and are arranged in the accommodation space along the first wire groove 10. Such an arrangement can reduce the occupied space of the negative ion emission end 200. The main line is divided into two branch lines in the accommodation space, that is, it is divided into the high-voltage wire harness 3 and the grounding wire harness 4, and the high-voltage wire harness 3 and the grounding wire harness 4 are arranged in the second wire groove 81 and the third wire groove 91 respectively.

[0056] Further, the first wire groove 10, the second wire groove 81 and the third wire groove 91 together form a Y-shaped structure, and the opening of the Y-shaped structure faces the first limit portion 7. It can be understood that the second wire groove 81 and the third wire groove 91 are arranged obliquely, so that a lateral thrust toward the first limit portion 7 can be applied to the high-voltage wire harness 3 and the ground wire harness 4 respectively, so as to further limit the horizontal movement of the high-voltage wire harness 3 and the ground wire harness 4 after assembly.

[0057] Furthermore, the first wire groove 10 is formed by the first wire groove 10 provided in the upper shell 1 and the second wire groove 81 provided in the lower shell 2. In practical applications, before assembly, the main line is first placed in the first wire groove 10, and then in the process of buckling the lower shell 2 and the upper shell 1, the first wire groove 10, the second wire groove 81 and the third wire groove 91 can be closed, so that the main line and the two branch lines can be locked to avoid deformation of the main line in the subsequent encapsulation process.

[0058] In this embodiment, the negative ion emitting end 200 further includes a positioning component 11, which is disposed in the accommodating space and is used to position the upper shell 1 and the lower shell 2. Under the action of the positioning component 11, it is possible to avoid damage to the high-voltage wire harness 3 and the grounding wire harness 4 due to misalignment of the upper shell 1 and the lower shell 2 during the buckling process.

[0059] Specifically, the positioning assembly 11 includes a first positioning member 111 and a second positioning member 112. The first positioning member 111 is arranged on the upper shell 1; the second positioning member 112 is arranged on the lower shell 2, and the first positioning member 111 and the second positioning member 112 are arranged correspondingly and matched. Among them, the first positioning member 111 is preferably a positioning pin, and the second positioning member 112 is preferably a positioning hole matched with the positioning pin. Before the upper shell 1 and the lower shell 2 are buckled, it is first necessary to ensure that the positioning pin and the positioning hole are aligned so that the two can complete the positioning.

[0060] In this embodiment, the negative ion emitting end 200 further includes a snap-fit ​​assembly 12 for locking the upper shell 1 and the lower shell 2. After the upper shell 1 and the lower shell 2 are positioned, the snap-fit ​​assembly 12 can lock the upper shell 1 and the lower shell 2. This arrangement can further avoid the formation of a gap between the upper shell 1 and the lower shell 2.

[0061] Specifically, the buckle assembly 12 includes a male buckle 121 and a female buckle 122, wherein the male buckle 121 is disposed on the upper shell 1; the female buckle 122 is disposed on the lower shell 2, and the male buckle 121 and the female buckle 122 are disposed and matched with each other. It can be understood that after the upper shell 1 and the lower shell 2 are positioned and in a fitted state, the male buckle 121 and the female buckle 122 can lock the upper shell 1 and the lower shell 2.

[0062] Based on the above, the present embodiment further proposes a vehicle-mounted air purification device, which includes an air duct 100 and the negative ion emitting end 200 as described above, a mounting hole is provided on the side wall of the air duct 100, the negative ion emitting end 200 is provided in the mounting hole, and a sealing ring is provided between the negative ion emitting end 200 and the mounting hole to improve the sealing of the air duct 100. The vehicle-mounted air purification device suitable for the negative ion emitting end 200 can not only reduce the occupied space of the vehicle-mounted air purification device, but also improve the assembly efficiency of the negative ion emitting end 200.

[0063] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
