As shown in fig. 1 and 2, an embodiment of the present invention provides a wire-passing sealing structure 100, where the wire-passing sealing structure 100 includes: a reinforcing member 110; the reinforcing member 110 may be fixed by an interference fit, and the reinforcing member 110 has a wire hole 110a for fixing the wire 400 by an interference fit.
As an example, the present invention provides a wire passing sealing structure 100 for sealing a wire 400 on a household appliance, such as the wire 400 between a multi-way valve (not shown in the drawings) and a circuit board 300 on a water softener shown in fig. 3 and 4, wherein the multi-way valve is located in a containing cavity formed between an upper shell 200 and a lower shell (not shown in the drawings) of soft water, the circuit board 300 is disposed on the upper shell 200, and a mounting hole 200a (shown in fig. 4) is disposed on the upper shell 200, so that the wire 400 on the multi-way valve can be passed out. The structure of the wire passing sealing structure 100 as described above will be described with respect to a water softener, for example, in which the reinforcement 110 of the wire passing sealing structure 100 is mounted in the mounting hole 200a of the upper case 200 by means of interference fit. It should be noted that the outline of the reinforcing member 110 is adapted to the structure of the mounting hole 200a on the upper casing 200, for example, if the structure of the mounting hole 200a is a substantially rectangular structure as shown in fig. 3, the outer casing of the reinforcing member 110 is also a substantially rectangular structure; similarly, the structure of the wire hole 110a is also adapted to the cross-sectional profile of the wire 400, for example, if the cross-sectional profile of the wire 400 is circular, the wire hole 110a is a circular hole.
The wire-passing sealing structure 100 can be applied to the field of electrical appliances, such as water softeners, and the reinforcing member 110 is installed in the installation hole 200a of the upper casing 200 of the water softener in an interference fit manner, so that a gap between the reinforcing member 110 and the installation hole 200a of the upper casing 200 can be avoided; the wire hole 110a of the reinforcing member 110 can be in interference fit with the wire 400 penetrating through the wire hole, so that the wire 400 of the multi-way valve on the water softener hermetically penetrates through the wire hole 110a of the reinforcing member 110 to be electrically connected with the circuit board 300 on the upper shell 200, a gap between the wire 400 and the wire hole 110a can be avoided, the wire 400 can be fixed, the wire 400 is prevented from shaking, signals between the circuit board 300 and the multi-way valve can be effectively transmitted, and the normal use of the water softener is ensured.
In some embodiments of the present invention, as shown in fig. 1 and 2, the reinforcing member 110 further has a through seam 110b which can be squeezed and deformed and is communicated with the wire feeding hole 110 a. The over-seam 110b on the reinforcing member 110 is deformed by pressing, so that the lead 400 can be pressed to penetrate through the over-seam 110b and enter the wiring hole 110a on the reinforcing member 110, and the problem that the plug connector with large size is difficult to penetrate through the wiring hole 110a on the reinforcing member 110 because the plug connector is installed on the end part of the lead 400 can be avoided. It should be noted that the width of the seam 110b is not greater than 0.5mm in a natural state (i.e., without being squeezed by the outside), so that foreign matters are not easy to enter the water softener through the seam 110b, and the sealing performance of the water softener can be ensured. During processing, the reinforcement member 110 may be cut directly to form the seam 110 b.
Alternatively, the seam 110b may be in a straight shape, a bent shape, a wavy shape, or a combination thereof. The in-line threading seam 110b is preferred because it facilitates the processing and the extrusion of the wire 400 therethrough.
As shown in fig. 5, in some embodiments of the present invention, a sealing groove 110c is disposed on a side wall of the reinforcing member 110, and the reinforcing member 110 is fixed by an interference fit at a groove bottom of the sealing groove 110 c. That is, the diameter of the middle portion of the reinforcement 110 is smaller than the diameters of both ends, and in case of shaking of the water softener, the head portion of the reinforcement 110 can block the reinforcement 110 from falling off from the mounting hole 200a of the water softener upper case 200, thereby improving the mounting firmness of the wire passing sealing structure 100 on the water softener upper case 200.
It should be noted that the shape of the sealing groove 110c is adapted to the structure of the mounting hole 200a on the upper casing 200, for example, if the structure of the mounting hole 200a is a substantially rectangular structure as shown in fig. 4, the sealing groove 110c is also a substantially rectangular structure;
in some embodiments of the present invention, the reinforcement member 110 is a rubber ring or a silicone ring. The reinforcing member 110 can simplify the structure of the reinforcing member 110 on the premise that the sealing groove 110c, the wire routing hole 110a and the cross seam 110b can be fully deformed. Of course, if the reinforcing member 110 is made of rubber or silicone as a whole, a rubber layer or a silicone layer that can be squeezed and deformed may be provided on the groove bottom of the sealing groove 110c, the hole wall of the wire hole 110a, and the slit wall of the wire passing slit 110 b.

It is understood that the size of the gripping cavity 210a is less than or equal to the diameter of the wire 400.
Alternatively, as shown in fig. 6, the reinforcement member includes: two fixing protrusions 211 are provided at intervals on the upper case 200, and a gap between the two fixing protrusions 211 constitutes a clamping chamber 210 a. The fixing protrusion 211 may be a long strip structure, and may be integrally formed with the upper case 200. In addition, the fixing protrusion 211 may be made of a material that can be slightly deformed by pressing, such as plastic.
