In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

First, the technical concept of the present invention will be explained. The steam mop in the prior art has a universal internal structure, and comprises a control circuit board 500, a steam generator 400, a water tank 300 and a water pump 900, wherein a heating element is arranged in the steam generator 400. In assembling, the above elements are closely arranged in a limited space in the steam generating device of the steam mop for compact arrangement. However, the heat generated by the heating element is relatively large, and if the layout is not reasonable, the heat dissipation is affected, and the heat generated by the heating element also affects the operation of other elements, even causes the element damage.

Therefore, the inventor thinks that the excessive heat emitted by the heating element and the control circuit board 500 can be absorbed by the mounting position of the water tank 300 in the limited cavity space in the steam generating device, and the heating element and the control circuit board 500 can be isolated, so that the influence of the heating element on the control circuit board 500 is avoided.

The specific scheme is as follows: as shown in fig. 1 to 3, a steam generating device of a steam mop 100 includes: the water heater comprises a shell 200, a control circuit board 500, a water tank 300, a water pump 900, a steam generator 400 and a heating element, wherein the control circuit board 500, the water tank 300, the water pump 900 and the steam generator 400 are arranged in the shell 200; the control circuit board 500 and the water pump 900 are fixed at a position close to the water tank 300, the steam generator 400 is fixed at a position far from the control circuit board 500, and the water tank 300 is located between the control circuit board 500 and the steam generator 400.

The control circuit board 500 is a core control element of the steam mop 100, and is used for controlling the on/off of the switch, controlling the operation of the water pump 900, and controlling the steam generator 400 to generate steam, and in some cases, can also realize the gear adjustment of the steam amount. Therefore, the operating environment temperature of the control circuit board 500 directly affects the operation stability, the operation efficiency and the service life of the steam mop 100.

By mounting the steam generator 400 at a position remote from the control circuit board 500, the influence of heat generated from the heat generating components on the control circuit board 500 is greatly reduced. The water tank 300 is installed at a position close to the control circuit board 500, and heat generated by the operation of the control circuit board 500 itself can be absorbed by water in the water tank 300, thereby improving the heat dissipation effect of the control circuit board 500. The water tank 300 is located between the control circuit board 500 and the steam generator 400, so that direct influence of heat generated by the heating elements inside the steam generator 400 on the control circuit board 500 is reduced, and water in the water tank 300 can absorb a large amount of heat emitted from the heating elements. Install water pump 900 in the position that is close to water tank 300, as shown in fig. 5, be equipped with a breach with water tank 300 bottom, water pump 900 installs in the breach position, can be absorbed the produced heat of water pump 900 self work by the water in the water tank 300 on the one hand, improves water pump 900's radiating effect, and on the other hand reduces the water flow path between water pump 900 and the water tank 300, improves the pump and pumps efficiency.

The end of the steam generator where the air outlet 201 is defined is the top of the steam generator, the control circuit board 500 may be installed in the casing 200 of the steam generator near the bottom, and correspondingly, the steam generator 400 may be installed in the casing 200 of the steam generator near the top, and the control circuit board 500 and the steam generator 400 are respectively disposed at two ends of the inner space of the casing 200.

As shown in fig. 4, the outer wall of the case 200 is provided with a second opening 202, and the water tank 300 is provided with a water level display sidewall 301, the water level display sidewall 301 being located at the second opening 202, the water level display sidewall 301 constituting a portion of the case 200.

First, the water level display sidewall 301 may facilitate a user to view the water level inside the water tank 300 to prevent a dry-fire situation from occurring and protect the elements inside the steam generating device. Secondly, since the water level display sidewall 301 directly forms a part of the housing 200, heat conducted from the steam generator in the water tank 300 can be directly dissipated to the outside of the steam generating device through the water level display sidewall 301, thereby reducing the influence on the control circuit board.

The outer case 200 of the water level display sidewall of the water tank 300 is designed to be in a boss shape, the shape of the second opening 202 is the same as that of the boss sidewall, and the boss of the water tank 300 can be clamped inside the second opening 202 during installation without other fixing structures. The water level display sidewall 301 is in the same curved surface or plane as the case 200 of the steam generating device. It should be noted that the opening shown in fig. 4 is smaller, and in the practical application process, the opening can be designed to be larger without affecting the holding, and correspondingly, the water level display side wall is also matched with the opening, so that the contact area between the outer wall of the water tank and the outside air is larger, and the heat dissipation efficiency is improved.

Considering the compact structure of the steam mop 100, the assembly process and the assembly cost, the elastic button 402 is made of an elastic rubber. The hole for accommodating the boss 401 on the elastic buckle 402 should be smaller than the outer wall size of the boss 401, so that the elastic buckle 402 can keep high resilience when buckled on the boss 401, and is fixed on the boss 401 through elasticity.
