Therefore, the lower part of the insulating anti-skid layer is provided with the supporting layer, the supporting layer is made of a material with higher rigidity, such as an ABS material, and the insulating anti-skid shell is supported between the palm of a user and the bottom shell through the supporting layer. The supporting layer and the insulating antiskid layer can be fixed together in an adhesive mode. The supporting layer outer fringe so stretch out in insulating skid resistant course, on the one hand because be convenient for install the supporting layer in the mounting groove, on the other hand because there is comparatively obvious clearance between mounting groove and the insulating skid resistant shell for the electricity is revealed to take place through the clearance, and in order to avoid this kind of condition to take place, go into the mounting groove with the outer fringe card of supporting layer, the separation has followed the clearance between mounting groove and the insulating skid resistant shell.

It should be noted that, in order to prevent the rotation between the supporting layer and the insulating anti-slip layer along the positioning pin, the positioning pin needs to be designed into a non-cylindrical structure. The positioning pin and the insulating anti-slip layer are of an integrated structure.

In a preferred implementation mode, the outer wall of the insulating anti-skid shell is provided with an arc-shaped structure, the main shell is provided with an air outlet end, and the insulating anti-skid shell is arranged close to the air outlet end in a bending and extending mode.

For improving user experience, the arc structure of the outer wall of the insulating anti-skid shell is set to be matched with the shape of the palm of a user. In the in-service use process, the tiger's mouth department of user's hand front end forefinger and thumb can touch with the handle unavoidably, and this region is close to the end of giving vent to anger, and the end of giving vent to anger can give off more heat, influences the temperature of main casing body surface, needs to protect this region, consequently with the one end of insulating anti-skidding shell to the crooked extension of user's hand, avoids the higher region of user's hand tiger's mouth direct contact main casing body front end temperature, protects the user.

First, the technical concept of the technical solution disclosed in the present invention will be explained. Steam generating device among the prior art for shaping, convenient assembling, design for handle and main casing body integral type structure, but this kind of structure has inconvenience in the use. The main shell of the steam generating device is usually made of injection molding materials, a heating element such as a steam generator is installed inside the steam generating device, even if heat insulation protection is provided, heat can be gradually conducted to the main shell, if the main shell is used for a long time, the temperature of the main shell is too high, and if the handle and the main shell are of an integrated structure, the handle can be affected by the temperature of the main shell, has higher temperature, and affects the use experience of a user, especially the palm center of a palm sensitive to the temperature; in addition, possible electrical leaks inside the steam generating device may directly affect the user holding the handle

Therefore, the inventor thinks that the handle can be split into the bottom shell and the heat insulation part on the premise of ensuring that the handle and the main shell are integrated, wherein the heat insulation part faces the palm center of the human body, so that the integrated structure of the steam generating device is ensured, the insulation effect of the handle part is met, and the heat influence in the using process is reduced.

The specific scheme is as follows: as shown in fig. 1 to 3, a steam generating device of a steam mop includes a main housing 100 and a handle coupled to the main housing 100, the handle includes a grip housing 200 defining a cavity, and the grip housing 200 includes a bottom housing 210 and an insulating anti-slip housing 220.

The main housing 100 of the steam generating device of the steam mop is a part directly contacting with a user, and the handle is generally integrally formed with the main housing 100. The heat inside the steam generating device may directly affect the user holding the handle.

The grip portion of the handle is divided into the bottom case 210 and the insulating anti-slip case 220, the insulating anti-slip case 220 faces the palm portion of the user, the bottom case 210 can be integrally formed with the main case 100 to reduce the assembly steps, the insulating anti-slip case 220 needs to be separately arranged from the bottom case 210, heat on the insulating anti-slip case 220 and the main case 100 is prevented from being directly conducted to the insulating anti-slip case 220 through the bottom case 210, the palm portion sensitive to temperature can be protected, and the palm portion is prevented from being scalded.

The bottom case 210 is provided with a mounting groove 211 in which the insulating non-slip case 220 is inserted. As disclosed above, the holding shell is composed of two parts made of different materials, and the bottom shell and the insulating anti-slip shell can be of an integrated structure or a split structure. When the bottom case 210 and the insulating anti-slip case 220 are of an integral structure, the bottom case 210 and the insulating anti-slip case 220 may be formed as a grip case by a two-shot molding method. When the bottom case 210 and the insulating anti-slip case 220 are a split structure, the bottom case 210 may be provided in a form of having a mounting groove, and the insulating anti-slip case 220 is mounted inside the mounting groove 211 in an embedded manner.

The main housing 100 may be formed as a vertically split structure, and may be formed by fastening the upper housing and the lower housing and then fastening them with screws. In other embodiments, the upper and lower housings may also be mounted together by a snap fit.

When the main housing 100 is injection molded, a handle portion is reserved, a portion of the grip housing 200 is integrally molded with the main housing 100, the housing defining the integrally molded portion is a bottom housing, another portion of the grip housing 200 is an insulating anti-slip housing 220 assembled with the bottom housing, and the insulating anti-slip housing 220 faces the palm center of the user.

As disclosed above, the main housing 100 is a split structure of an upper housing and a lower housing, and the bottom housing 210 is integrally formed with the main housing 100, so that the bottom housing 210 is divided into an upper portion and a lower portion. A groove formed at the edge of the bottom case 210 defines a mounting groove 211 for mounting the insulating non-slip case 220.

As shown in fig. 8, the incoming line protecting sleeve 300 comprises a bunching part 330, a limiting ring groove 320 and a limiting table 310, wherein the limiting table 310 is located at the tail end of the bunching part 330, the limiting table 310 limits the bunching part 330 inside the supporting layer 222, the limiting ring groove 320 is located at the position where the bunching part 330 is close to the limiting table 310, and the circumferential side wall of the limiting ring groove 320 is matched with the circumferential side wall of the incoming line hole 223.

Spacing annular groove 320 is used for realizing the spacing to inlet wire protective sheath 300, and during the installation, spacing annular groove 320 can direct joint inside inlet wire hole 223. Because the area of the limiting table 310 is larger than the wire inlet hole 223, after the wire harness portion 330 passes through the wire inlet hole 223, the limiting table 310 cannot further pass through, so that the wire harness portion 330 is limited in the main housing 100, and the wire inlet protective sleeve 300 is prevented from being pulled out of the housing by external force, so that the wire harness cannot be protected.

The inner wall of the support layer 222 is provided with a limit inner groove 229, and the shape of a groove body formed by the inner wall of the limit inner groove 229 is the same as the shape of the outer wall of the periphery of the limit table 310.

The retaining inner groove 229 is used to fix the retaining block 310, so that the retaining block 310 can be accurately snapped into the retaining inner groove 229.

Further, because the inlet wire protective sheath 300 is installed in the inlet wire hole 223 through the form of joint, the inlet wire protective sheath 300 has the possibility of rotating along the inlet wire hole 223, and the rotation of the inlet wire protective sheath 300 needs to be limited in order to prevent the rotation of the inlet wire protective sheath 300 from causing the wire to be twisted. If the limiting table 310 is configured as a square body, the limiting inner groove 229 matched with the limiting table 310 is also in a square body groove shape, and the limiting table 310 cannot rotate in the limiting inner groove 229 under the limitation of a non-circular shape, i.e. the wire is protected and prevented from being twisted.
