Description

Technical Field

[0001] This utility model relates to the field of cleaning appliance technology, and in particular to a steam cleaning device with a handheld control accessory. Background Technology

[0002] A steam cleaner is a device that uses high-temperature, high-pressure steam for cleaning, featuring environmental friendliness, high efficiency, and multifunctionality. Its working principle involves a heating element that rapidly converts water into high-temperature, high-pressure steam. When water is heated to its boiling point, the movement of water molecules intensifies, turning it into steam. Within a confined space, this steam continuously accumulates, increasing pressure and forming high-temperature, high-pressure steam with powerful cleaning capabilities. This steam accelerates the movement of dirt molecules, breaking down the bonds between dirt particles, thus eliminating various stubborn stains. It also removes bacteria, mites, microorganisms, and pathogens attached to objects.

[0003] Example 1 of the prior art, referring to patent document CN220001647U, discloses a steam fabric cleaning machine, including a main body, with rollers at the bottom of the main body, an installation cavity formed inside the main body, and a clean water tank for storing clean water and a wastewater tank for recycling wastewater inserted in the installation cavity; the main body is provided with a water outlet pipe assembly connected to the clean water tank and a water return pipe assembly connected to the wastewater tank, and a rotating connecting pipe is provided on the main body, the water outlet pipe assembly and the water return pipe assembly are connected to both ends of the rotating connecting pipe, and a connecting part for connecting a brush head hose is provided on the side of the rotating connecting pipe, the brush head hose being used to connect a brush head tool.

[0004] Example 2 of the prior art, referring to patent document CN219289365U, discloses a handle assembly and a fabric cleaning machine. The handle assembly includes: a handle piece with an adapter at one end and a first limiting part on the adapter; and a cleaning accessory connected to the handle piece, having an adapter hole and a second limiting part on the outer side of the corresponding adapter hole. When the adapter is inserted into the adapter hole and rotated by a preset angle, the first and second limiting parts engage. Therefore, by providing a first limiting part on the adapter and a second limiting part on the cleaning accessory, and by ensuring that the first and second limiting parts engage when the adapter is inserted into the adapter hole and rotated by a preset angle, the installation of the handle piece and the cleaning accessory is facilitated, allowing users to easily replace the cleaning accessory and enabling the fabric cleaning machine to meet user needs.

[0005] In summary, as shown in Technical Example 1, existing steam cleaners mostly have their on / off and flow control components located at the main unit. As shown in Technical Example 2, the handle assembly has a relatively simple structure, only offering length adjustment and lacking integrated on / off and flow control components. Therefore, during cleaning, the user holds the cleaning attachment at a distance (approximately 1-3 meters) from the main unit, making it impossible to control the steam on / off and flow rate via the attachment. The user must go to the main unit to access these functions. This results in two problems: firstly, it is very inconvenient and user-unfriendly; secondly, while approaching the main unit, steam continuously sprays outwards, making it difficult to control the direction of the handle assembly.

[0006] This leads to steam waste, and the ejected steam can pose certain safety hazards, such as causing high-temperature damage to furniture. Summary of the Invention

[0007] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a steam cleaning device with a handheld control accessory.

[0008] The technical solution of this utility model to solve its technical problem is: a steam cleaning device with a handheld control accessory, comprising:

[0009] A steam cleaning unit is provided with a steam generating element inside. The steam cleaning unit has a water inlet and a steam outlet that communicate with the steam generating element.

[0010] Cleaning head attachment, used to exhaust high-temperature steam;

[0011] The handheld control accessory has one end connected to the steam outlet via a steam pipe, and the other end detachably connected to the cleaning head accessory.

[0012] The handheld control accessory is equipped with an internal steam pipeline, and the handheld control accessory is equipped with a steam outlet switch valve and a flow regulating valve;

[0013] The steam outlet switch valve acts on the internal steam pipeline to block or open the internal steam pipeline;

[0014] The flow regulating valve acts on the internal steam pipeline to control the flow rate through the internal steam pipeline.

[0015] The preferred embodiment of the steam outlet switch valve in this utility model is that the steam outlet switch valve includes a push switch, a switch valve body, a switch valve core, and a first return spring.

[0016] The push-button switch extends at least partially beyond the handheld control accessory;

[0017] The switch valve body has a first steam inlet port and a first steam outlet port, and the internal steam pipeline is connected to the first steam inlet port and the first steam outlet port respectively;

[0018] The switch valve core is movably disposed in the switch valve body, and the switch valve core is capable of blocking or opening the first steam inlet port and the first steam outlet port;

[0019] The switch valve core has a drive end extending out of the switch valve body, and the push switch forms a transmission engagement with the switch valve core through the drive end;

[0020] The first reset spring is disposed in the switch valve body and abuts against the switch valve core. Under the action of the elastic force of the first reset spring, the switch valve core always has the tendency to block the first steam inlet port and the first steam outlet port.

[0021] Furthermore, the first steam inlet port and the first steam outlet port are staggered along the height direction;

[0022] The switch valve core includes a switch valve core body and a first sealing ring sleeved on the switch valve core body. When the height of the first sealing ring is between the height of the first steam inlet port and the first steam outlet port, the first sealing ring seals the first steam inlet port and the first steam outlet port.

[0023] A more preferred embodiment of the steam outlet switch valve in this utility model is that the steam outlet switch valve further includes a safety lock mechanism, and the safety lock mechanism has at least a safety lock unlocked state and a safety lock locked state.

[0024] When the safety lock mechanism is in the unlocked state, the push switch can be pressed;

[0025] When the safety lock mechanism is in the safety lock locked state, the push switch is restricted and cannot be pressed.

[0026] A preferred embodiment of the safety lock mechanism in this utility model is that the safety lock mechanism includes a locking block, the push switch has a receiving groove, the locking block is at least partially located in the receiving groove, and the locking block is rotatably connected to the push switch.

[0027] The locking block has a toggle end and a locking end;

[0028] The actuating end extends outside the receiving groove;

[0029] The handheld control accessory has a safety lock slot. When the toggle end is operated, the locking end enters the safety lock slot, and the locking end abuts against the safety lock slot to form a limiting fit, thereby restricting the push switch and preventing it from being pressed. When the toggle end is operated, the locking end moves away from the outside of the safety lock slot, and the locking end separates from the safety lock slot to provide room for movement, thereby allowing the push switch to be pressed.

[0030] The preferred embodiment of the flow regulating valve in this utility model is that the flow regulating valve includes a rotary regulating switch, a flow valve body, and a flow valve core.

[0031] The rotary adjustment switch extends at least partially beyond the handheld control accessory;

[0032] The flow valve body has a second steam inlet port and a second steam outlet port, and the internal steam pipeline is connected to the second steam inlet port and the second steam outlet port respectively.

[0033] The flow valve core is movably disposed in the flow valve body, and the flow valve core is located between the second steam inlet port and the second steam outlet port, and the flow valve core forms a transmission cooperation with the rotary regulating switch.

[0034] Furthermore, the flow valve core includes a flow valve core body and a second sealing ring sleeved on the flow valve core body, wherein the second sealing ring abuts against the inner wall of the flow valve body and forms a sealing fit.

[0035] An optional embodiment of this utility model is provided, wherein the handheld control accessory is further provided with a connection locking mechanism, and the handheld control accessory is detachably connected to the cleaning head accessory through the connection locking mechanism.

[0036] Furthermore, the connection locking mechanism includes a connecting block, which has a connecting latch end and a pressing end;

[0037] The cleaning head accessory is provided with a connecting groove, and the end of the connecting buckle can extend upward and snap into the connecting groove to assemble the cleaning head accessory onto the handheld control accessory;

[0038] Pressing the pressing end causes the connecting buckle end to retract downwards and exit outside the connecting groove, thereby engaging the locking mechanism between the cleaning head accessory and the handheld control accessory.

[0039] More specifically, it also includes a second return spring, which abuts against the inner wall of the connecting block and the handheld control accessory. The elasticity of the second return spring acts on the connecting block so that the connecting block always has an upward extension tendency.

[0040] The beneficial effects of this utility model are as follows:

[0041] 1. The on / off control component (steam outlet valve) and the flow control component (flow regulating valve) are both integrated into the handheld control accessory. During use, the user holds the handheld control accessory and can operate the steam on / off and flow rate without needing to approach the steam cleaning unit. This makes operation very convenient, avoids steam waste, and eliminates the potential safety hazards of high-temperature steam when approaching the steam cleaning unit.

[0042] II. The safety lock mechanism primarily functions as a child lock. When the safety lock is engaged, the push-button switch is restricted and cannot be pressed, thus blocking the internal steam pipeline to prevent steam from escaping and causing a safety accident.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0060] Example 1

[0061] Reference Figures 1-12 A steam cleaning device with a handheld control accessory, comprising:

[0062] The steam cleaning unit 1 contains a steam generating element 11 (preferably a steam boiler). The steam cleaning unit 1 has a water inlet 12 and a steam outlet 13 communicating with the steam generating element 11. A cleaning head attachment 2 is used to discharge high-temperature steam. Multiple cleaning head attachments 2 can be provided, each with different shapes and functions, and they are interchangeable. The user selects one cleaning head attachment 2 according to real-time needs. A handheld control attachment 3 has one end connected to the steam outlet 13 via a steam pipe, and the other end detachably connected to the cleaning head attachment 2.

[0063] Reference Figure 8 Unlike existing technologies, the handheld control accessory 3 of this invention includes an internal steam pipeline 31. The handheld control accessory 3 is equipped with a steam outlet valve 4 and a flow regulating valve 5. The steam outlet valve 4 acts on the internal steam pipeline 31 to block or open it; the flow regulating valve 5 acts on the internal steam pipeline 31 to control the flow rate through it. It should be noted that the internal steam pipeline 31 is not necessarily a single steam pipe; it can consist of one steam pipe or multiple steam pipes combined, depending on the internal structural requirements of the handheld control accessory 3 to satisfy its steam inlet and outlet functions.

[0064] The steam cleaning equipment obtained by adopting the structural scheme of this utility model integrates the switch control component (steam outlet switch valve 4) and the flow control component (flow regulating valve 5) into the handheld control accessory 3. During use, the user holds the handheld control accessory 3 and can operate the steam on / off and flow rate without having to approach the steam cleaning host 1. Therefore, the operation is very convenient, avoids steam waste, and eliminates the potential safety hazards of high-temperature steam when approaching the steam cleaning host 1.

[0065] Example 2

[0066] Based on the structure of Embodiment 1, this embodiment provides a preferred composition scheme for multiple components, as detailed below:

[0067] 1. Steam outlet switch valve 4: Refer to Figure 5The device includes a push-button switch 41, a switch valve body 42, a switch valve core 43, and a first return spring 44. The push-button switch 41 extends at least partially beyond the handheld control accessory 3, allowing the user to easily access and press it. The switch valve body 42 has a first steam inlet port 421 and a first steam outlet port 422. The internal steam pipeline 31 is connected to both the first steam inlet port 421 and the first steam outlet port 422, enabling the steam outlet switch valve 44 to function as a steam inlet and outlet valve. The switch valve core 43 is movably disposed within the switch valve body 42. Movement of the switch valve core 43 relative to the switch valve body 42 changes its relative position, allowing it to block or open the first return spring 44. The valve body 42 has an inlet port 421 and an outlet port 422. The valve core 43 has a drive end 431 extending out of the valve body 42. The push switch 41 is connected to the valve core 43 via the drive end 431, so that when the user operates the push switch 41, the valve core 43 can be moved by the push switch 41. The first return spring 44 is disposed in the valve body 42 and abuts against the valve core 43. Under the elastic force of the first return spring 44, the valve core 43 always has the tendency to block the inlet port 421 and the outlet port 422.

[0068] When the user presses the push switch 41, the switch valve core 43 is displaced, which connects the first steam inlet port 421 and the first steam outlet port 422 to enable steam output. When the user releases the push switch 41, the switch valve core 43 returns to its initial position under the elastic force of the first return spring 44, disconnecting the first steam inlet port 421 and the first steam outlet port 422, thus blocking the steam output. At this time, no more steam is released.

[0069] Furthermore, the first steam inlet port 421 and the first steam outlet port 422 are staggered along the height direction. The switch valve core 43 includes a switch valve core body 432 and a first sealing ring 433 sleeved on the switch valve core body 432. When the height of the first sealing ring 433 is between the heights of the first steam inlet port 421 and the first steam outlet port 422, the first sealing ring 433 blocks the first steam inlet port 421 and the first steam outlet port 422. Along the height direction, when the first sealing ring 433 is on the same side of the first steam inlet port 421 and the first steam outlet port 422, the seal fails, and the first steam inlet port 421 and the first steam outlet port 422 are connected. Compared with the distribution structure at the same height, this utility model preferably adopts a staggered arrangement of the first steam inlet port 421 and the first steam outlet port 422, so that when the first sealing ring 433 is between them, the risk of leakage is effectively reduced and the sealing performance is improved.

[0070] II. Safety Lock Mechanism 6: (Refer to...) Figure 5 , Figure 10 The safety lock mechanism 6 has at least a safety lock unlock state and a safety lock locked state; when the safety lock mechanism 6 is in the safety lock unlock state, the restriction is removed and the push switch 41 can be pressed; when the safety lock mechanism 6 is in the safety lock locked state, the restriction is effective and the push switch 41 is restricted and cannot be pressed.

[0071] More specifically, the safety lock mechanism 6 includes a locking lever 61. The push switch 41 has a receiving groove 411. The locking lever 61 is at least partially located in the receiving groove 411 and is rotatably connected to the push switch 41. The locking lever 61 has a toggle end 611 and a locking end 612. The toggle end 611 extends outside the receiving groove 411. The handheld control accessory 3 has a safety lock groove 32. The toggle end 611 is operated so that the locking end 612 enters the safety lock groove 32, and the locking end 612 abuts against the safety lock groove 32 and forms a limiting fit, thereby restricting the push switch 41 and preventing it from being pressed. The toggle end 611 is operated so that the locking end 612 moves away from the outside of the safety lock groove 32, and the locking end 612 separates from the safety lock groove 32 and provides room for movement, thereby allowing the push switch 41 to be pressed.

[0072] The safety lock mechanism 6 is primarily designed as a child lock. When the safety lock mechanism 6 is in the locked state, the push switch 41 will be restricted and cannot be pressed, thereby blocking the internal steam pipeline 31 to prevent steam from being ejected and causing a safety accident. When the safety lock mechanism 6 is in the unlocked state, the steam outlet valve 4 can be activated normally, enabling the steam to be released upon pressing.

[0073] III. Flow regulating valve 5: (Refer to...) Figure 6 The system includes a rotary regulating switch 51, a flow valve body 52, and a flow valve core 53. The rotary regulating switch 51 extends at least partially beyond the handheld control accessory 3 for easy user operation. The flow valve body 52 has a second steam inlet port 521 and a second steam outlet port 522. The internal steam pipeline 31 is connected to the second steam inlet port 521 and the second steam outlet port 522 respectively, enabling the flow valve body 52 to perform steam inlet and outlet functions. The flow valve core 53 is movably disposed within the flow valve body 52, located between the second steam inlet port 521 and the second steam outlet port 522, and forms a transmission connection with the rotary regulating switch 51.

[0074] The flow regulating valve 5 functions similarly to a flow ball valve. Specifically, during the user's operation of the rotary regulating switch 51, the flow valve core 53 undergoes a relative position change with respect to the flow valve body 52, thereby regulating the flow rate. Preferably, the flow valve core 53 has a blocking section 531, the area of ​​which gradually increases in size along the circumference to achieve different steam interception effects.

[0075] Furthermore, the flow valve core 53 includes a flow valve core body 532 and a second sealing ring 533 sleeved on the flow valve core body 532. The second sealing ring 533 abuts against the inner wall of the flow valve body 52 and forms a sealing fit to prevent steam from leaking from the connection between the flow valve core body 532 and the rotary regulating switch 51.

[0076] Example 3

[0077] In the technical field of steam cleaning equipment, in order to achieve cleaning of different locations or objects, multiple cleaning head attachments 2 are often configured. These attachments vary in shape and size to meet different usage scenarios. Therefore, the multiple cleaning head attachments 2 need to be detachably connected to the handheld control attachment 3. Based on the above, the preferred solution provided in this embodiment is as follows: (Refer to...) Figure 7 The handheld control accessory 3 is also provided with a connection locking mechanism 7, and the handheld control accessory 3 and the cleaning head accessory 2 are detachably connected and cooperated through the connection locking mechanism 7.

[0078] Specifically, the connection locking mechanism 7 includes a connecting block 71, which has a connecting latch end 711 and a pressing end 712. The cleaning head accessory 2 has a connecting groove 21, and the connecting latch end 711 can extend upwards and engage with the connecting groove 21 to assemble the cleaning head accessory 2 onto the handheld control accessory 3. In use, pressing the pressing end 712 causes the connecting latch end 711 to retract downwards and exit outside the connecting groove 21, thus locking the cleaning head accessory 2 and the handheld control accessory 3. The user can then easily pull the cleaning head accessory 2 away from the handheld control accessory 3.

[0079] More specifically, it also includes a second return spring 72, which abuts against the inner wall of the connecting block 71 and the handheld control accessory 3. The elasticity of the second return spring 72 acts on the connecting block 71, so that the connecting block 71 always has an upward extension tendency. That is, when the cleaning head accessory 2 needs to be assembled onto the handheld control accessory 3, when the connecting buckle end 711 is aligned with the connecting groove 21, the elastic force of the second return spring 72 will act on the connecting block 71, causing the connecting buckle end 711 on the connecting block 71 to automatically engage into the connecting groove 21, thereby locking and assembling the cleaning head accessory 2 and the handheld control accessory 3.

[0080] It is worth noting that the other technical solutions of this utility model are all existing technologies, and therefore will not be described in detail.

[0081] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
