Description

Technical Field

[0001] This utility model relates to the field of steam cleaning machine technology, and in particular to a steam cleaning machine. Background Technology

[0002] Traditional steam cleaners consist of a casing, a switch assembly, an electrical control assembly, and a boiler. These components are housed within the casing. The switch assembly connects or disconnects the power supply, the boiler generates steam, and the electrical control assembly controls the boiler's operation. The switch assembly, electrical control assembly, and boiler occupy a significant amount of space. Furthermore, the boiler is a high-voltage component, while the electrical control assembly is a low-voltage component. To prevent interference, there is typically a gap between the boiler and the electrical control assembly. Additionally, the boiler has a steam outlet that extends outwards, further occupying space. This structure results in a relatively large overall size and a less compact layout for the steam cleaner.

[0003] In addition, boilers are generally fixed inside the outer casing with screws, but screw installation is cumbersome and inefficient. Furthermore, the boiler operates at a high temperature, and the screws can easily loosen due to thermal expansion and contraction under prolonged high temperatures, which can lead to boiler failure. The high temperature generated during boiler operation can also affect other electrical components, such as the control board and microswitches. In addition, the high temperature of the boiler can also be transferred to the outer casing, making users susceptible to burns when operating the steam cleaner.

[0004] Therefore, further improvements are necessary. Utility Model Content

[0005] The purpose of this invention is to provide a steam cleaner that is simple in structure, compact in layout, small in size, has good heat insulation effect, is safe and reliable, and is highly practical, so as to overcome the shortcomings of the prior art.

[0006] A steam cleaner designed for this purpose includes a housing, a switch assembly, an electrical control assembly, and a boiler. The housing is characterized by having an electrical cavity inside, the switch assembly and the boiler installed within the electrical cavity, the electrical control assembly installed outside the electrical cavity, a first gap between the boiler and the electrical control assembly, the switch assembly disposed within the first gap, and a positioning assembly between the switch assembly and the housing, wherein the switch assembly is positioned and installed on the housing via the positioning assembly.

[0007] The boiler includes a main body and an outer cover. Several elastic positioning elements are provided on the outer side of the main body, and several positioning holes are provided on the inner side of the outer cover. The positioning elements are inserted into the positioning holes, and the positioning elements are interference-fitted with the hole walls of the positioning holes so that the main body is positioned inside the outer cover. A positioning mounting part is provided between the outer cover and the outer shell, and the outer cover is positioned and mounted on the outer shell through the positioning mounting part.

[0008] The positioning assembly includes a positioning edge disposed on the switch assembly and a first positioning groove disposed inside the housing. The positioning edge is inserted into the first positioning groove to position the switch assembly inside the electrical cavity. The positioning assembly also includes a first fixing hole on the switch assembly and a first fixing post hole inside the housing. After the fastener passes through the first fixing hole, it is fastened to the first fixing post hole so that the switch assembly is fixed on the housing.

[0009] A steam outlet extending outward is provided on one side of the boiler. The steam outlet is located within the first interval, and the switch assembly is provided with an air-proof notch for the steam outlet.

[0010] The switch assembly includes a bracket, a micro switch, and a toggle. The bracket is positioned on the housing, the micro switch is installed inside the bracket, and the toggle is slidably disposed on the bracket. When the toggle slides, it acts on or disengages from the micro switch to connect or disconnect the power supply. The toggle is provided with a toggle part, and the micro switch is provided with a trigger part. When the toggle slides, the toggle part acts on the trigger part or disengages from the trigger part. The bracket is provided with a guide hole, and the toggle part is slidably disposed on the guide hole. The actuating element is provided with an operating part for moving the actuating element, and the housing is provided with a sliding hole. The operating part is slidably disposed on the sliding hole, and the operating part extends out of the housing at least partially through the sliding hole.

[0011] Several pins are provided on the outer side of the main body, and the positioning component is provided with a socket. The pins are inserted into the socket to fix the positioning component on the main body. The outer side of the positioning component is provided with a raised rib, which is interference-fitted with the wall of the positioning hole.

[0012] The positioning and mounting part includes a positioning boss on the outer cover and a second positioning groove inside the outer cover. The positioning boss is inserted into the second positioning groove, and a limit rib is provided in the second positioning groove. The side of the positioning boss abuts against the limit rib. A positioning hole is provided in the positioning boss. The positioning and mounting part also includes a second fixing hole on the outer cover and a second fixing post hole inside the outer shell. After the fastener passes through the second fixing hole, it is fastened to the second fixing post hole so that the outer cover is fixed to the outer shell.

[0013] The outer cover includes a first cover body and a second cover body, with a first receiving cavity formed between the first cover body and the second cover body, and the main body is disposed in the first receiving cavity; the first cover body is provided with a fastening hole, and the second cover body is provided with a fastening rib, which fastens with the fastening hole to connect the first cover body and the second cover body. The first cover is provided with a positioning slot, and the second cover is provided with a positioning rib. The positioning rib is inserted into the positioning slot.

[0014] The electrical control assembly includes a mounting cover and an electrical control board. The electrical control board is fixed inside the mounting cover and is electrically connected to the boiler and the micro switch respectively. A retaining edge is provided on one side of the outer casing, which is located outside the electrical cavity. A retaining groove is provided on the mounting cover, and the retaining edge is engaged with the retaining groove to fix the mounting cover to the outer casing.

[0015] The housing includes a first housing and a second housing that are snapped together, with an electrical cavity formed between the first housing and the second housing.

[0016] This utility model's steam cleaner features an electrical cavity within its outer casing. A switch assembly and a boiler are installed within this cavity, while an electrical control assembly is mounted outside. A first gap exists between the boiler and the electrical control assembly. The switch assembly and the boiler's steam outlet are also located within this first gap. The switch assembly has a venting notch for preventing air from escaping through the steam outlet. This structure fully utilizes the space between the boiler and the electrical control assembly, resulting in a very compact overall layout and significantly reduced overall size. Furthermore, a positioning assembly part is provided between the switch assembly and the outer casing. The switch assembly is positioned and installed on the casing via this part, enabling rapid positioning and installation, thus improving assembly efficiency. Designing the switch assembly as an independent module (including a support base, microswitch, and toggle element) allows for sub-assembly outside the production line before being mounted onto the outer casing via the support base, greatly improving production efficiency and assembly consistency.

[0017] Furthermore, by designing the boiler into two parts—the main body and the outer casing—the outer casing provides insulation, preventing the high temperatures generated by the boiler's main body during operation from affecting other electrical components. It also prevents the high temperatures from being transferred to the outer casing and causing burns to users. In addition, several flexible positioning elements are set on the outside of the main body, and several positioning holes are set on the inside of the outer casing. The positioning elements are inserted into the positioning holes, and the positioning elements are interference-fitted with the hole walls, so that the main body is positioned inside the outer casing. The flexible connection can effectively cope with thermal expansion and contraction and is less likely to loosen in long-term use than the screws of the rigid connection, making the fixation of the main body more reliable. Moreover, this connection method is easy to operate and greatly improves assembly efficiency. The outer casing is fixed to the outer casing with screws. Due to the heat insulation effect of the outer casing, the high temperatures generated by the boiler's main body during operation are basically not transferred to the screws, thus effectively preventing the screws from loosening.

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] See Figures 1-21 This steam cleaner includes a housing 1, a switch assembly 2, an electrical control assembly 3, and a boiler 4. An electrical cavity 5 is provided inside the housing 1. The switch assembly 2 and the boiler 4 are installed inside the electrical cavity 5, while the electrical control assembly 3 is installed outside the electrical cavity 5 to prevent the high temperature and steam generated by the boiler 4 from reaching the electrical control assembly 3. A first gap 6 exists between the boiler 4 and the electrical control assembly 3. The boiler 4 is a high-voltage component, and the electrical control assembly 3 is a low-voltage component. The first gap 6 prevents mutual interference between the two. The switch assembly 2 is located within the first gap 6, making full use of the space. The first gap 6 also serves as a heat dissipation channel for the boiler 4, helping the electrical control assembly 3 stay away from the heat of the boiler 4. A positioning assembly is provided between the switch assembly 2 and the housing 1, allowing the switch assembly 2 to be positioned and installed on the housing 1.

[0041] The boiler 4 includes a main body 50 and an outer cover 51. The outer side of the main body 50 is provided with several elastic positioning members 52, and the inner side of the outer cover 51 is provided with several positioning holes 53. The positioning members 52 are inserted into the positioning holes 53, and the positioning members 52 are interference-fitted with the hole wall of the positioning hole 53 so that the main body 50 is positioned inside the outer cover 51.

[0043] The positioning assembly also includes a first fixing hole 9 provided on the switch assembly 2 and a first fixing post hole 13 provided in the housing 1. After the fastener (screw) passes through the first fixing hole 9, it is fastened to the first fixing post hole 13 so that the switch assembly 2 is fixed on the housing 1.

[0044] A steam outlet 10 extending outward is provided on one side of the boiler 4. The steam outlet 10 is located within the first interval 6, which can make full use of the space of the first interval 6. The switch assembly 2 is provided with an air-proof notch 11 for air-proofing the steam outlet 10, so as to prevent the switch assembly 2 and the steam outlet 10 from interfering with each other.

[0045] There is a gap between one end of the boiler 4 and the side wall of the electrical cavity 5 to form a receiving space 12. The switch assembly 2 extends at least partially into the receiving space 12. The positioning edge 7, the first positioning groove 8, the first fixing hole 9 and the first fixing post hole 13 are located on the receiving space 12. The space between the end of the boiler 4 and the side wall of the outer shell 1 is usually unavoidable and belongs to the "leftover" area. This structure transforms it into the receiving space 12, making the whole structure more compact and further reducing the volume.

[0046] A lug 28 is provided on one side of the switch assembly 2. The lug 28 is located in the middle of the positioning edge 7 and is located in the receiving space 12. The first fixing hole 9 is provided on the lug 28.

The bracket 14 is provided with a sliding groove 29. The toggle 16 is slidably disposed on the sliding groove 29. When the toggle 16 slides, it acts on the micro switch 15 or disengages from the micro switch 15 to connect or disconnect the power supply.

[0048] The bottom of the toggle member 16 is provided with a toggle part 17, and the micro switch 15 is provided with a trigger part 18. When the toggle member 16 slides, the toggle part 17 acts on or disengages from the trigger part 18 to connect or disconnect the power supply. The bracket 14 is provided with a guide hole 19, and the toggle part 17 is slidably disposed on the guide hole 19 to prevent the toggle member 16 from deviating when sliding, so that the toggle part 17 can act precisely on the trigger part 18.

[0049] The top of the toggle member 16 is provided with an operating part 20 for moving the toggle member 16. The housing 1 is provided with a sliding hole 21. The operating part 20 is slidably disposed on the sliding hole 21. The operating part 20 extends out of the housing 1 at least partially through the sliding hole 21, thereby facilitating manual movement of the toggle member 16 through the operating part 20.

[0050] A sealing gasket 30 is fitted on the actuating element 16. The sealing gasket 30 is located between the actuating element 16 and the side wall of the electrical cavity 5 to seal the gap between the actuating element 16 and the outer casing 1, preventing external moisture or dust from entering the electrical cavity 5.

[0051] The bracket 14 includes a base 31 and a cover plate 32 covering the base 31. A second receiving cavity 33 is formed between the base 31 and the cover plate 32. A micro switch 15 is installed in the second receiving cavity 33. A positioning edge 7, a lug 28, a sliding groove 29 and a guide hole 19 are provided on the cover plate 32.

[0052] A plurality of insert posts 54 are provided on the outer side of the main body 50, and an insertion hole 55 is provided in the positioning member 52. The insert posts 54 are inserted into the insertion hole 55 so that the positioning member 52 is fixed on the main body 50. In this embodiment, the insert posts 54 are respectively provided on both sides of the main body 50, that is, the positioning member 52 is respectively provided on both sides of the main body 50. Correspondingly, the positioning holes 53 are respectively provided on both sides of the outer cover 51.

[0053] The outer side of the positioning member 52 is provided with a raised rib 56, which is interference-fitted with the hole wall of the positioning hole 53. Several raised ribs 56 are provided and distributed vertically on the positioning member 52. The positioning member 52 is made of rubber material.

[0054] The positioning and mounting part includes a positioning boss 57 on the outer cover 51 and a second positioning groove 58 inside the outer shell 1. The positioning boss 57 is inserted into the second positioning groove 58 so that the boiler 4 is positioned in the electrical cavity 3. A limiting rib 59 is provided in the second positioning groove 58, and the side of the positioning boss 57 abuts against the limiting rib 59. A positioning hole 53 is provided in the positioning boss 57. The positioning bosses 57 are respectively provided on the upper and lower sides of the outer cover 51, and the second positioning grooves 58 are distributed vertically on the outer shell 1.

[0055] The positioning and mounting part also includes a second fixing hole 60 provided on the outer cover 51 and a second fixing post hole 61 provided in the outer shell 1. After the fastener (screw) passes through the second fixing hole 60, it is fastened to the second fixing post hole 61 so that the outer cover 51 is fixed on the outer shell 1.

[0056] There is a second gap 69 between the outer wall of the main body 50 and the inner wall of the outer cover 51. The second gap 69 is a heat dissipation channel for the main body 50. The high temperature generated by the main body 50 during operation will not be directly transferred to the outer cover 51, but will reach the outer cover 51 after passing through a certain distance. This can reduce the heat transferred to the outer cover 51, further reduce the impact of the high temperature generated by the main body 50 during operation on other electrical components, and further prevent the high temperature from being transferred to the outer casing 1. In addition, the outer cover 51 also has a heat preservation effect, reducing the heat loss of the main body 50 and improving the heating efficiency of the boiler 4.

[0057] The outer cover 51 includes a first cover body 62 and a second cover body 63, with a first receiving cavity 64 formed between the first cover body 62 and the second cover body 63, and the main body 50 is disposed in the first receiving cavity 64; the first cover body 62 is provided with a fastening hole 65, and the second cover body 63 is provided with a fastening rib 66, which fastens with the fastening hole 65 to connect the first cover body 62 and the second cover body 63; The first cover 62 has a first semi-circular hole 70 on each side, and the second cover 63 has a second semi-circular hole 71 on each side.

[0059] The first cover 62 is provided with a positioning slot 67, and the second cover 63 is provided with a positioning rib 68. The positioning rib 68 is inserted into the positioning slot 67 to position the first cover 62 and the second cover 63 relative to each other.

[0060] Steam outlet 10 is located at one end of the main body 50, and a through hole 72 is provided at one end of the outer cover 5. Steam outlet 10 extends out of the outer cover 51 through the through hole 72 and into the electrical cavity 3, so that steam outlet 10 can be connected to a steam pipe.

[0061] The electrical control assembly 3 includes a mounting cover 22 and an electrical control board 23. The electrical control board 23 is fixed inside the mounting cover 22 and is electrically connected to the boiler 4 and the micro switch 15.
