Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of steam cleaning equipment, especially a hand-held steam cleaner with a dual-function switch. BACKGROUND

[0002] A steam cleaner is a device that uses high-temperature and high-pressure steam for cleaning, and has the characteristics of environmental protection, high efficiency, and multi-function. The working principle is that the water is rapidly converted into high-temperature and high-pressure steam by a heating device. When the water is heated to the boiling point, the water molecules move faster and become water vapor. In a closed space, water vapor accumulates and pressure increases, forming high-temperature and high-pressure steam with strong cleaning ability. This steam can accelerate the movement speed of dirt surface molecules and destroy the binding force between dirt, thereby achieving the purpose of eliminating stubborn stains. At the same time, it can also eliminate bacteria, mites, microorganisms, and pathogens attached to objects.

[0003] Prior art example 1, see patent document CN209034959U, a hand-held steam cleaner is disclosed, which separates the preheating and steam cleaning operations, allowing the steam cleaning operation to be performed in a wireless state, making it convenient and safe to use. The hand-held steam cleaner for achieving the foregoing object includes a cleaner body having a first coupler; a power supply seat including a second coupler and a power cord electrically connected to the second coupler; wherein the first coupler and the second coupler can be coupled to each other, the cleaner body obtains power from an external power source through the first coupler, the second coupler, and the power cord to generate steam, and the cleaner body can release steam outward in an offline manner. Example 1 has the following defects: since the button is exposed to the shell and does not have a safety protection structure, children or the elderly are likely to cause steam to be ejected outward due to pressing the button, which poses a safety hazard.

[0004] The utility model discloses a safe steam cleaner. Children are prone to scalding due to accidental triggering of the steam cleaner, which poses a safety hazard. The utility model discloses a shell and a boiler arranged in the shell. The shell is provided with a steam outlet connected with the boiler. Steam generated by the boiler is sprayed outward through the steam outlet. A control valve is arranged between the boiler and the steam outlet. A child lock assembly is arranged on the shell. The child lock assembly can be switched between a locking position to prevent the control valve from being opened and an unlocking position to allow the control valve to be opened. The child lock assembly in the locking position prevents the control valve from being opened, thereby preventing the steam outlet from spraying steam outward due to accidental triggering of the control valve by children, preventing scalding, and ensuring safety. Technical example 2 addresses the shortcomings of technical example 1 by providing a child lock protection function. However, example 2 also has some shortcomings. Specifically: 1. If operated with one hand, the arrangement of the child lock assembly and the control valve makes the operation actions not coherent. Specifically, the operating hand needs to first unlock the child lock assembly from the side, and then adjust the holding method (usually rotating the operating hand by 90 degrees) before operating the control valve. The two actions are relatively independent, so the operation is two-stage and relatively troublesome. 2. If operated with both hands, one hand needs to unlock the child lock assembly, and the other hand needs to operate the control valve, which is not very convenient. 3. After use, the child lock assembly needs to be manually reset, which cannot be automatically reset. 4. Manually resetting the child lock assembly has some operation difficulty. If not operated properly, the child lock assembly may fail to function, i.e., the control valve can still be pressed, which still poses a safety hazard. 5. After use, the user is prone to forgetting to reset the child lock assembly, which poses a safety hazard.

[0054] Example one

[0055] Refer to Figures 1-13 A handheld steam cleaner with dual-function switch, comprising: a handheld cleaner housing 1, which has a water inlet 11 and a steam outlet 12;Steam boiler 2 is arranged in the interior of the handheld cleaner housing 1, the water inlet 11 is communicated with the steam boiler 2, and the steam boiler 2 is communicated with the steam outlet 12 through the steam outlet channel 21;Steam switch mechanism 3 acts on the steam outlet channel 21 to block or conduct the steam outlet channel 21;Child lock switch mechanism 4 is installed on the steam switch mechanism 3, and the child lock switch mechanism 4 has at least release position state 4b and lock position state 4a. The steam switch mechanism 3 moves along the first direction 3X, and the child lock switch mechanism 4 moves along the second direction 4X.

[0056] The working principle of the associated action between the child lock switch mechanism 4 and the steam switch mechanism 3 is: when the child lock switch mechanism 4 is in the lock position state 4a, the child lock switch mechanism 4 and the handheld cleaner housing 1 form structural interference, so that the steam switch mechanism 3 is limited and cannot be operated by the user;When the child lock switch mechanism 4 is in the release position state 4b, the child lock switch mechanism 4 and the handheld cleaner housing 1 are free from structural interference, so that the steam switch mechanism 3 can be operated by the user.

[0057] It is emphasized that the child lock switch mechanism 4 in the present disclosure is directly integrated to the steam switch mechanism 3, both of which are combined together in physical structure, eliminating the distance in space. Thus, the operating hand holds the handheld cleaning machine shell 1, and generally the thumb of the operating hand can contact the child lock switch mechanism 4, and apply force to the child lock switch mechanism in the first direction 3X to switch it to the release position state 4b, and then apply force to the child lock switch mechanism in the second direction 4X, which drives the steam switch mechanism 3 to move to open the steam outlet channel 21, realizing the steam outlet function. Therefore, the scheme of the present utility model can control the child lock switch mechanism 4 and the steam switch mechanism 3 by a single operating hand; only a single force applied by the thumb to the child lock switch mechanism (specifically in the direction of the intersection point of the first direction 3X and the second direction 4X) is needed to first unlock the child lock switch mechanism and then immediately open the steam switch mechanism 3. It is worth mentioning that there is no need to switch the posture and position of the operating hand and the thumb, and the operation is continuous and similar to a one-step action, so the operation is very fast and convenient.

[0058] Preferably, the first direction 3X is a horizontal direction, and the second direction 4X is a vertical direction. When the user operates, only the forward and downward force applied by the thumb to the child lock switch mechanism is needed, which is ergonomic and easier to operate.

[0059] Preferably, the handheld cleaning machine shell 1 has a handheld section 13, and the steam switch mechanism 3 and the child lock switch mechanism 4 are arranged on the handheld section 13. Thus, the user can hold the handheld cleaning machine shell 1, operate the steam switch mechanism 3, and operate the child lock switch mechanism 4 by a single hand.

[0060] Embodiment Two

[0061] In this embodiment, a preferred structure of the steam switch mechanism 3 is provided, which is described with reference to Figures 2-13 , specifically: the steam switch mechanism 3 includes a push switch 31, a transmission block 32, and a switch valve core assembly 33. The handheld cleaning machine shell 1 is provided with a mounting groove 131 to provide a mounting space, and the push switch 31 is assembled into the mounting groove 131 and at least partially exposed outside the handheld cleaning machine shell 1 after passing through the mounting groove 131, so as to facilitate the user to contact and control the push switch 31; one end of the transmission block 32 is in transmission cooperation with the push switch 31, and the other end is in transmission cooperation with the switch valve core assembly 33, so as to realize the transmission connection among the push switch 31, the transmission block 32, and the switch valve core assembly 33. The switch valve core assembly 33 at least partially extends into the steam outlet channel 21, and the switch valve core assembly 33 can block or open the steam outlet channel 21 during movement.

[0062] When the user presses the press switch 31, the press switch 31 drives the switch valve core assembly 33 through the transmission block 32, so that the switch valve core assembly 33 is displaced to open the steam outlet channel 21; when the user releases the press switch 31, the press switch 31, the transmission block 32 and the switch valve core assembly 33 can be reset together, so that the switch valve core assembly 33 is reset to block the steam outlet channel 21.

[0063] More specifically, regarding the preferred structure of the switch valve core assembly 33, specifically: the switch valve core assembly 33 includes a switch valve core body 331, a first sealing member 332 arranged on the switch valve core body 331 and a first reset spring 333. Among them, the steam outlet channel 21 has a small diameter section 211 and a large diameter section 212, and the connection between the small diameter section 211 and the large diameter section 212 forms a transition port 21a; the switch valve core body 331 is in clearance fit with the small diameter section 211, so the switch valve core body 331 mainly plays a structural support role and cannot block the steam outlet channel 21 alone; the first sealing member 332 is located in the large diameter section 212, the first sealing member 332 is in clearance fit with the large diameter section 212, and the first sealing member 332 is arranged on the switch valve core body 331; when the press switch 31 is pressed, the press switch 31 drives the switch valve core body 331, and under the drive of the switch valve core body 331, the first sealing member 332 is separated from the transition port 21a to open the large diameter section 212 and the small diameter section 211; when the press switch 31 is released, the switch valve core body 331 is reset, and under the drive of the switch valve core body 331, the first sealing member 332 abuts against the transition port 21a to block the transition port 21a. It is worth mentioning that the first reset spring 333 directly or indirectly acts on the switch valve core assembly 33, so that the switch valve core assembly 33 always has a movement trend to block the steam outlet channel 21. When the press switch 31 is released, the first reset spring 333 resets the switch valve core assembly 33.

[0064] On the other hand, the hand-held cleaner housing 1 is fixedly provided with a second sealing ring 14, the switch valve core body 331 passes through the second sealing ring 14 and enters the steam outlet channel 21, and the second sealing ring 14 is in interference fit with the hand-held cleaner housing 1 and the switch valve core body 331 respectively, to prevent steam from leaking from the assembly gap between the rear end of the switch valve core body 331 and the hand-held cleaner housing 1.

[0065] Optionally, a second reset spring 34 is further included, and the second reset spring 34 acts on the transmission block 32, so that the transmission block 32 always has a movement trend away from the switch valve core assembly 33. Under the combined action of the first reset spring 333 and the second reset spring 34, the steam switch mechanism 3 resets more smoothly and accurately.

[0066] In this embodiment, a preferred structure of the transmission block 32 is provided, which is specifically as follows: referring to Figure 13 , the transmission block 32 has a main body part 321, a power input part 322 formed on the main body part 321, and a power output part 323, the power input part 322 is in transmission cooperation with the press switch 31, the power output part 323 is in transmission cooperation with the switch valve core assembly 33, and the main body part 321 is in rotation cooperation with the hand-held cleaner shell 1 through a rotating shaft structure. The rotating shaft structure is preferably a rotating shaft body 3211 integrally formed on the main body part 321, and the hand-held cleaner shell is provided with a rotating hole (which is a conventional design structure and is not shown in the figure), and the rotating shaft body 3211 is inserted into the rotating hole, so that the main body part 321 can rotate relative to the hand-held cleaner shell 1.

[0067] Embodiment three

[0068] In this embodiment, a preferred structure of the child lock switch mechanism 4 is provided, referring to Figure 5 、 Figure 7 、 Figure 10 , specifically as follows: including a push switch 41 and a third reset spring 42, the push switch 41 is movably installed into the accommodating groove 311, and the third reset spring 42 is connected between the push switch 41 and the inner wall of the accommodating groove 311; wherein the third reset spring 42 acts on the push switch 41, so that the push switch 41 always has a movement trend to switch to the locked position state 4a.

[0069] The working principle of the push switch 41 is that: the hand-held cleaner shell 1 has an interference area 15; when the push switch 41 is in the locked position state 4a, the push switch 41 forms structural interference with the interference area 15; when the push switch 41 is in the released position state 4b, the push switch 41 is misaligned with the interference area 15, so as to eliminate the structural interference.

[0070] Preferably, a guide groove 312 is formed on the side wall of the accommodating groove 311, the push switch 41 has a guide block 411 on the side wall, the guide block 411 can extend into the guide groove 312 and move along the guide groove 312, so as to play a guiding role, and the movement path of the push switch 41 is more stable.

[0071] It is worth noting that other technical solutions of the utility model belong to the prior art, and therefore are not described in detail.

[0072] The above merely describes preferred embodiments of the present application, and it should be noted that, for those ordinarily skilled in the art, without departing from the concept of the present application, some improvements and refinements can be made, and these improvements and refinements should also be considered as falling within the protection scope of the present application.
