[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 2 and 4The utility model provides a sliding touch switch, including a housing 100 and a sensing unit 200. The housing 100 is provided with a sliding touch area K parallel to the sensing unit 200. When a finger slides in the sliding touch area K, a touch signal is generated to control the switch, wherein the sensing unit 200 is sealed by the housing 100.

[0027] This embodiment does not require soft glue sealing, physical buttons and mechanical switches, has a simple structure and low mold costs; products using sliding touch switches occupy little internal space; the sliding touch switch eliminates physical buttons and does not damage the integrity of the appearance; the product openings are reduced and the waterproof sealing effect is good.

[0028] When this embodiment is used specifically, when a finger contacts the corresponding pad sensing area, the pad discharge time becomes longer, thereby generating a touch signal. The signal generated by the first pad alone is marked as 1, the touch signal sensed by the first and second pads at the same time is marked as 2, and the signal generated by the second pad alone is marked as 3. By analogy, a signal array similar to {1, 2, 3, 4, 5} can be obtained according to the touch sequence. The touch signal is collected every 10 ms. When the signal value is different from the previous signal value, the signal value is put into the array. Every 10 signals are processed once, and continuous values ​​are screened. When 4 continuous values ​​are generated, such as {1, 2, 1, 2, 3, 4, 3, 5, 4, 1}, the fragment {1, 2, 3, 4} is extracted from the array as 4 continuous values, and it is determined that a sliding touch behavior has occurred. It is also recognized that it is an increasing array and is determined as a slide-up start signal, thereby realizing a sliding touch switch.

[0029] Specifically, the outer shell 100 is sealed and the waterproof soft glue is eliminated, so the structure is simpler and the integrity of the appearance is not damaged.

[0030] In one embodiment, the sensing unit 200 is a PCBA, on which at least three sensing areas 201 are disposed, and the size of each sensing area 201 is not less than 10 mm*10 mm.

[0031] In this embodiment, if the sensing area 201 is too large, the sensitivity will be too high and it will be easy to trigger by mistake. If the area is too small, the sensitivity will be insufficient and the triggering will be difficult.

[0032] Specifically, the sensing area 201 is a touch pad, and adjacent sensing areas are spaced apart from each other without contacting each other. The sensing area 201 is connected to the single-chip microcomputer through a wire, and when a finger slides between the sensing areas 201, a 2N-1 level touch signal is generated to control the switch.

[0033] In one embodiment, the housing 100 is a non-conductive body. This embodiment is configured in this way to enhance the sensing effect when the finger slides. Specifically, the housing 100 can be made of plastic or other non-conductive materials.

[0034] In one embodiment, see Figure 3 and Figure 5 , the housing 100 is in a long strip shape.

[0035] In one embodiment, a filling entity 300 is disposed in the area formed between the housing 100 and the sensing unit 200. This embodiment is configured in this way to enhance the sensing effect when a finger slides.

[0036] In one embodiment, the filling entity 300 is a non-conductive body.

[0037] In one embodiment, the filling body 300 is integrally arranged with the housing 100. This arrangement of the embodiment can reduce the difficulty of product assembly and improve efficiency.

[0038] In one embodiment, the filling entity 300 is independently provided with the housing 100. This arrangement of the present embodiment facilitates the maintenance and replacement of the filling entity 300 at a later stage, thus improving convenience.

[0039] In one embodiment, the filling entity 300 may be made of plastic, foam or silicone.

[0040] A nose hair trimmer includes the above-mentioned sliding touch switch. It should be noted that the sliding touch switch in this solution is not limited to use on nose hair trimmers, but can be used on any other electronic device using a mechanical switch, regardless of whether the electronic device has waterproof performance requirements.

[0041] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that satisfy both A and B. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
