[0002] With the continuous and rapid development of my country's GDP, consumer income continues to grow, especially the rapid growth of residents' income level in large and medium-sized cities. With the improvement of people's living standards and quality, residents' living conditions continue to improve, and they have higher requirements for the quality of living environment. A new cleaning tool (steam mop) came into being.
[0003] For example, the steam mop works by heating water to generate pressure and high temperature, and directly disinfects and sterilizes the home environment through high-temperature and high-pressure steam. Steam mops generally have functions such as high-temperature sterilization and oil removal. Using high pressure to generate steam can both clean and sterilize, and easily deal with difficult dirt. Whether it is the greasy dirt on the kitchen range hood that is difficult to clean, the mold growth in the humid bathroom, or the car engine and interior, etc., the steam mop quickly removes dirt, saving time and effort, and is economical and affordable. No detergent needs to be added, which is completely in line with the economic principle.
[0004] Traditional steam mops all use one-way steam exhaust, that is, a steam outlet is set at the lower end of the mopping component, and a mop is set at the lower end of the mopping component, so that steam is sprayed from the steam outlet to the mop, and then the mop is used to mop the floor. This structure has certain defects, for example: the steam is first sprayed on the mop, rather than directly sprayed on the ground, so the cleaning and sterilization effect will be reduced, and the spraying direction is single, and the cleaning effect on stubborn dirt is poor overall; even if the mop is removed during use, the user cannot observe the specific steam outlet position because it is set at the lower end, so it cannot be effectively controlled and used.
[0005] To this end, the inventor has developed a steam outlet structure for a household steam mop, such as patent document CN212879182U, which includes a mop body, the mop body includes an outer shell, a control component and a steam generating component arranged in the outer shell, and a floor mop component for cleaning and mopping the floor, the floor mop component has a plurality of steam outlets, and the mop body is provided with a reversing valve, the steam inlet end of the reversing valve is connected to the steam generating component, and the steam outlet end of the reversing valve is connected to the steam outlet.

Preferably, the reversing valve is arranged in the floor mop component, the foot switch is arranged on the floor mop component, and the floor mop component is also provided with a locking device for locking the position of the foot switch. More specifically, the foot switch is transmission-connected to the valve stem of the reversing valve, a locking rod is provided on the lower end surface of the foot switch, a group of locking clamp arms are provided in the locking device, locking grooves are formed between the locking clamp arms, and the locking rod can be inserted into the locking groove and interlocked with the locking clamp arms.
[0006] However, according to feedback from market users, the patented product of the above invention also has certain defects, such as: 1. The reversing valve and the locking device are arranged separately, so the pedal area becomes larger, and it is easy to step on the wrong side during the pedal operation, resulting in the reversing valve and the locking device being unable to work together at the same time; 2. The overall structure of the foot switch is very thin, with low strength and poor stability during use; 3. There is a lack of effective limit, anti-slip and guide structures, and it is extremely easy to malfunction after long-term use. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0042] Reference Figure 1 to Figure 14 A switch switching structure of a steam cleaning device comprises a steam cleaning body 1, a plurality of steam outlets are provided on the steam cleaning body 1, a steam generator (not shown in the figure) is provided in the steam cleaning body 1, a switch is provided between the steam generator and the steam outlet, and the switch comprises:
[0043] A switch button 6 is movably arranged on the steam cleaning body 1, and a trigger member 7 is arranged on the switch button 6, and has at least a first position state 8 and a second position state 9;
[0044] A self-locking switch 16, which acts on the trigger member 7 to keep the switch button 6 in the first position state 8 or the second position state 9;
[0045] The reversing valve 10 is fixedly arranged on the steam cleaning body 1 and is connected to the steam outlet and the steam generator respectively. The switch button 6 can abut against the reversing valve 10 and drive the reversing valve 10 to adjust;
[0046] The guide anti-slip mechanism comprises a guide hole 11 provided on the steam cleaning body 1, a guide column 12 protruding from the switch button 6, a connecting screw 13 and a limiting gasket 14; wherein the guide column 12 is passed through the guide hole 11 and can move along the guide hole 11; the guide column 12 is also provided with a connecting hole 15, and the connecting screw 13 is screwed with the connecting hole 15; the limiting gasket 14 is sleeved on the connecting screw 13, and the limiting gasket 14 can abut against the steam cleaning body 1 and form a limiting anti-slip fit.
[0047] In the present invention, through the design and application of the guide anti-slip mechanism, the reversing valve 10, the switch button 6 and the self-locking switch 16 are spliced and combined together, and they cooperate with each other when used, so that the use effect of the switch switching structure is significantly improved. In the guide anti-slip mechanism, on the one hand, when the guide column 12 moves downward, the self-locking switch 16 and the trigger member 7 are used to achieve positioning and position retention; on the other hand, the connection screw 13 is used to limit and drive the limit gasket 14, so that the limit gasket 14 can move synchronously with the guide column 12, and at the same time, the contact between the limit gasket 14 and the steam cleaning body 1 can control the movement stroke of the guide column 12 to prevent the guide column 12 from moving upward excessively and disengaging from the guide hole 11.
[0048] The steam cleaning body 1 takes a steam mop as an example, and mainly includes a handheld host 2, a floor mop assembly 3, and a connecting pipe 4 connected between the handheld host 2 and the floor mop assembly 3. Preferably, a storage space 5 is provided on the floor mop assembly 3, and the switch button 6 is a foot switch button, and the foot switch button is arranged in the storage space 5. That is, when the user uses the steam mop, the handheld host 2 is controlled by the hand, and the foot switch button is controlled by the foot, so as to cooperate and control and use the steam mop more conveniently. Of course, the steam cleaning device in the present invention is not limited to the steam mop, and is only for illustration and reference here, without special limitation.
[0049] Preferably, the foot switch button is circular, and the circumferential side of the accommodating space 5 is provided with an annular movable groove 17 adapted to the foot switch button. By providing the annular movable groove 17, the foot switch button can be better limited and guided in the circumferential direction during the movement, so that the path of its movement is more stable. On the other hand, an air avoidance groove 19 for accommodating the pipeline 18 is also provided in the accommodating space 5, and the air avoidance groove 19 runs through the accommodating space. The provision of the air avoidance groove 19 facilitates the access of the pipeline 18 and the installation of accessories such as the reversing valve 10 on the one hand, and is also conducive to processing and more convenient for demolding and molding on the other hand.
[0050] The specific structure of the reversing valve 10 is as follows: it includes a valve body 20, a valve core 21, a steam inlet 22 and a steam outlet opened on the valve body 20, and a return spring 23 arranged in the valve body 20. The steam inlet 22 is connected to the steam generator, and the steam outlet is connected to the steam outlet. One end of the valve core 21 abuts against the return spring 23, and the other end of the valve core 21 extends out of the valve body 20 and can abut against the switch button 6. When in use, steam enters the valve body 20 from the steam inlet 22, and then is discharged from the steam outlet through the valve body 20; the movement of the valve core 21 relative to the valve body 20 plays a role of switching, reversing, etc.; after use, the return spring 23 causes the valve core 21 to return to its initial position.
[0051] The more preferred structural mode of the guide anti-slip mechanism is as follows: 1. A large gap 24 is formed between the outer wall of the guide column 12 and the inner wall of the guide hole 11, and a contact rib 25 is also convexly provided on the outer wall of the guide column 12, and a small gap 26 is formed between the contact rib 25 and the inner wall of the guide hole 11. By setting the large gap 24 and the small gap 26, the contact and friction between the outer wall of the guide column 12 and the inner wall of the guide hole 11 can be effectively reduced, so that the movement of the guide column 12 in the guide hole 11 is smoother and smoother, and the friction is effectively reduced to reduce the loss of parts and components and extend the service life; on the other hand, by setting the contact rib 25, when the switch button 6 is deflected due to force, the contact rib 25 can immediately abut against the inner wall of the guide hole 11, thereby preventing the guide column 12 from being excessively deflected, and then playing an effective guiding role, so that the movement of the guide column 12 is more stable and reliable.
[0052] In this embodiment, there are multiple guide posts 12, which are more reliable in structure, make the force more balanced, and provide better texture during operation. Furthermore, at least one of the guide posts 12 is provided with a guide positioning rib 27 on its outer wall, and a guide groove 28 is provided on the guide hole 11. The guide positioning rib 27 is slidably arranged in the guide groove 28 and can move along the guide groove 28. Under normal circumstances, there is always a certain gap between the contact rib 25 and the inner wall of the guide hole 11, so there will be more or less shaking and instability. Through the setting and coordinated use of the guide positioning rib 27 and the guide, on the one hand, the two are always in contact with each other, so as to always play a role in guiding and reducing shaking; on the other hand, since each accessory has a specific direction during installation, the existence of the guide positioning rib 27 can play a role in positioning and foolproofing during assembly, which is convenient for the staff to identify more quickly, prevent mis-assembly, and improve assembly efficiency.
[0053] In this embodiment, the valve body 20 includes a valve main body 30 with a steam passage 29 and a bottom cover 31 detachably connected to the lower end of the valve main body 30. The valve body 20 is assembled in a split manner, which is convenient for installing accessories such as the return spring 23 and the valve core 21 into the valve main body 30, and is also convenient for the maintenance of the valve body 20 in the later stage. Further, the exhaust port at least includes a first exhaust port 32 and a second exhaust port 33 provided on the valve main body 30. The first exhaust port 32, the steam inlet 22 and the second exhaust port 33 are arranged in sequence from top to bottom; the valve core 21 has a first blocking section 34, a steam passing section 35, a second blocking section 36, and a limiting section 37 acting on the first exhaust port 32, a steam passing section 35, and a steam passing gap between the steam passing section 35 and the inner wall of the valve body 20. One end of the return spring 23 abuts against the limiting section 37, and the other end abuts against the bottom cover 31. That is, the steam inlet 22 is located between the first steam exhaust port 32 and the second steam exhaust port 33, and the location setting is more reasonable, which can reduce the adjustment stroke and the steam passing stroke, effectively reduce the occurrence of blockage and jamming, and make the movement of the valve core 21 and the flow of steam smoother.
[0054] Preferably, the steam outlet includes at least a first steam outlet 38 and a second steam outlet 39, the first steam outlet 32 is communicated with the first steam outlet 38 through the pipeline 18, and the second steam outlet 33 is communicated with the second steam outlet 39 through the pipeline 18. The first steam outlet 38 can be arranged at the front end of the mop assembly 3, and the second steam outlet 39 is arranged at the lower end of the mop assembly 3. When in use, the user can selectively control the reversing valve 10 according to his own needs to achieve the purpose of changing the steam outlet and realize a better cleaning function.
[0055] In the present invention, the switch button 6 includes a button body 40 and a top cover 41 detachably connected to the upper end of the button body 40 to facilitate installation and use. Specifically, the top cover 41 is provided with a plurality of positioning posts 42 and buckles 43 protruding downward, the guide post 12 is arranged on the button body 40, and a positioning hole 44 is provided at the upper end of the guide post 12, and the positioning post 42 is inserted into the guide hole 11; the button body 40 is also provided with a locking groove 45, and the buckle 43 can be buckled into the locking groove 45. During assembly, the positioning post 42 is aligned with the positioning hole 44 and inserted, and when inserted into place, the buckle 43 is inserted into the locking groove 45 and forms a limited anti-dropping fit with the button body 40. In addition, in the above structure, the positioning hole 44 is directly provided on the guide post 12, which effectively utilizes the structure of the guide post 12, and makes the spatial layout more reasonable when the connection reliability is sufficient.
[0056] The valve core 21 and the switch button 6 are generally made of hard metal or plastic. During use, the two are constantly in contact and generate a certain impact force between each other, which may cause certain damage. After long-term use, the wear and tear may increase, which may lead to a decrease in matching accuracy, improper operation, or even failure. On the other hand, the two will constantly make a "dong dong dong" noise during use, which is not a good user experience. In order to solve the above defects, the present invention also includes a buffer gasket 46, a receiving groove 47 is provided between the button body 40 and the top cover 41, and the buffer gasket 46 is arranged in the receiving groove 47 and is located directly above the valve core 21; more specifically, in order to facilitate the installation of the buffer gasket 46 and ensure the position reliability of the buffer gasket 46 when it is used, a through hole 48 connected to the receiving groove 47 is opened on the button body 40, and the size of the through hole 48 is larger than the size of the valve core 21, and the size of the through hole 48 is smaller than the size of the buffer gasket 46.
[0057] In this embodiment, the upper end of the valve body 20 is screwed and fixed to the mop assembly 3, and the lower end of the valve body 20 is suspended in the air to achieve installation and fixation of the valve body 20.
[0058] When the present invention is used, the user can control the reversing valve 10 through the switch button 6 according to his own needs, so as to realize various personalized functions such as steam spraying from the lower end of the floor mop component 3, or from the front end of the floor mop component 3, or from both the lower end and the front end of the floor mop component 3, so as to meet the usage needs in different scenarios and further improve the overall cleaning ability of the steam mop for stubborn dirt.
[0059] The present invention optimizes and improves the structure of the switch switching structure of the original steam cleaning device, and its advantages are: 1. The structure of the reversing valve 10 and the switch button 6 is designed to achieve splicing combination. The two are independently produced and formed, and then combined with each other after splicing, so that the two are more coordinated during use, so there is less restriction on the pedal area, and the reversing valve 10 and the switch button 6 can be used together even if they are stepped on off during operation. 2. The structures of the reversing valve 10 and the switch button 6 intersect with each other, making the overall coordination more reliable, the strength is effectively improved, and the stability during use is better; 3. Various limit, anti-slip, and guide structures are added, so that the coordination between the various components is more stable and reliable, the failure rate is reduced, and it is conducive to long-term use.
[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment according to the technical essence of the invention still falls within the protection scope of the technical solution of the present invention.
