Description

Technical Field

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

[0002] Steam cleaning equipment achieves its cleaning function by generating high-temperature, high-pressure steam and is widely used in homes, commercial spaces, and other settings. However, existing steam cleaning equipment typically has fixed cleaning heads or is only compatible with specific equipment models. Users need to purchase multiple complete units for different cleaning scenarios (such as crevice cleaning, flat surface cleaning, and curved surface cleaning), resulting in resource waste.

[0003] For example, see patent document CN111053497A, which discloses a working head of a multifunctional steam cleaning device. The tail end of the working head is provided with a conveying pipeline along the central axis, and the tail end is configured as a snap-fit ​​interface that mates with a corresponding adapter. The head end of the working head is configured as a steam nozzle for different environments, and the steam nozzle is provided with a steam nozzle for spraying water vapor. The steam nozzle is connected to the conveying pipeline.

[0004] In summary, existing steam cleaning equipment typically uses mechanical locking switches to control the steam pipeline. During this process, the steam boiler continues to operate and supply steam to the spray gun attachment, which can cause a short-term increase in internal pressure, making it easy for steam to leak and causing safety issues. Furthermore, the user's operator needs to continuously control (press) the switch during this process, causing discomfort to the user.

[0005] Therefore, there is an urgent need for a cleaning head accessory that is versatile, easy to assemble and disassemble, safe and reliable, and a steam cleaning device that includes such an accessory. Summary of the Invention

[0022] In a preferred embodiment, a steam detection sensor is also included. A steam detection port is provided on the top of the steam boiler assembly. The steam detection sensor is installed at the steam detection port and is connected to the electromagnetic switch valve through a second wiring harness, so that a second detection circuit is formed between the electromagnetic switch valve and the steam detection sensor.

Detailed Implementation

[0049] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments are merely specific descriptions of the present invention, and their purpose is to enable those skilled in the art to better understand the technical solution of the present invention, and should not be regarded as limitations on the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] Example 1

[0053] Reference Figures 1-12 A cleaning head accessory 4, the cleaning head accessory 4 includes a universal adapter 41 and several nozzle bodies 42 of different shapes, the nozzle bodies 42 being detachably connected to a steam cleaning device via the universal adapter 41.

[0054] The steam cleaning equipment has a first electrical connection terminal assembly 13, and the universal adapter 41 has a second electrical connection terminal assembly 43. The first electrical connection terminal assembly 13 can contact the second electrical connection terminal assembly 43 and form an electrical connection.

[0055] The above describes the basic structural design of the cleaning head accessory 4. Its differences from existing technologies are at least as follows: 1. All nozzle bodies 42 are connected to the steam cleaning equipment via a single universal adapter 41, rather than each nozzle having its own adapter. Standardized mechanical connection interfaces are formed between the adapter and the equipment, and between the adapter and the nozzle, achieving interface unification. 2. A modular design is adopted, allowing the universal adapter 41 and nozzle body 42 to be repeatedly disassembled. 3. The cleaning head accessory 4 is electrified; through the cooperation of the first electrical connection terminal assembly 13 and the second electrical connection terminal assembly 43, electrical conductivity is achieved between the cleaning head accessory 4 and the steam cleaning equipment.

[0056] In a preferred embodiment, a plug-in assembly 22 is provided at the steam outlet port 12. The plug-in assembly 22 includes a plug-in base 221 and a flip cover 222 rotatably connected to the plug-in base 221. The plug-in base 221 has a first hole 223 and a second hole 224. The universal adapter 41 has a steam conduit 411, which is detachably connected to the front end of the first hole 223. The rear end of the first hole 223 is connected to and in communication with the internal pipeline 3. The first electrical connection terminal assembly 13 is inserted into the second hole 224 from back to front, and the second electrical connection terminal assembly 43 is detachably inserted into the second hole 224 from front to back. The first electrical connection terminal assembly 13 and the second electrical connection terminal assembly 43 make contact in the second hole 224 to achieve electrical connection.

[0057] The core structural features of the above-mentioned preferred configuration are as follows: 1. The connection structure of the steam outlet port 12 is designed as an integrated plug-in assembly 22, rather than a scattered independent component; among which, the plug-in base 221 serves as the fixed base for connection, bearing key structures such as holes and terminals, and is a transition component for the adapter to connect with the equipment; the rotating flip cover 222 is integrated on the plug-in base 221 through a rotating connection, providing protection and improving product integration and aesthetics. 2. Dual-hole functional partitioning, that is, physical isolation between steam transmission and electrical connection, greatly improves safety during use, ensures normal operation of functions, and reduces the risk of steam leakage and electrical failure. 3. Both steam connection and electrical connection adopt a directional adaptation connection design to ensure connection accuracy and stable steam transmission and electrical conduction.

[0058] Furthermore, a contact switch 421 is provided in the nozzle body 42, and the contact switch 421 is electrically connected to the second electrical connection terminal assembly 43 through the spray gun end wiring harness 422; a steam outlet switch 423 is provided on the nozzle body 42, and the steam outlet switch 423 is in contact with the contact switch 421. The contact switch 421 closes and the equipment emits steam only when all three conditions are met simultaneously: "adapter connection to equipment + nozzle installation adapter + operation of nozzle steam outlet switch 423". Since the nozzle is the part that the user directly holds during cleaning, by placing the steam outlet switch 423 on the nozzle body 42, the user can perform steam start / stop operations (such as pressing a trigger-type steam outlet switch 423) while holding the nozzle, without having to frequently lift their hand to operate the switches on the main unit of the equipment.

[0059] It is important to emphasize that this equipment features a single-trigger start-stop function for steam output. During steam output, the user does not need to continuously operate the nozzle steam output switch 423; a single trigger is sufficient to release it. Furthermore, when briefly shutting off the steam output during cleaning intervals, a single trigger followed by a circuit disconnection via the electromagnetic switch valve 51 replaces the conventional mechanical structure, preventing leaks and mitigating the risk of improper operation.

[0060] In a preferred embodiment, the universal adapter 41 includes an annular conductive base 412 through which the steam conduit 411 passes. The front end of the second electrical connection terminal assembly 43 is connected to the rear end of the annular conductive base 412, and the spray gun end wiring harness 422 extends into the universal adapter 41 and connects to the front end of the annular conductive base 412. The annular conductive base 412 enables coaxial integration and physical isolation between the steam transmission channel and the electrical connection channel, while simplifying the internal electrical wiring of the adapter and improving the reliability and assembly efficiency of the modular connection.

[0061] Example 2

[0062] Reference Figure 1 , Figures 7-12 This embodiment provides a steam cleaning device, including: a steam housing 1 having a water inlet port 11 and a steam outlet port 12; a steam boiler assembly 2 disposed within the steam housing 1, and the steam boiler assembly 2 being connected to the water inlet port 11 and the steam outlet port respectively via an internal pipe 3; a cleaning head accessory 4 detachably connected to the steam outlet port 12; an electromagnetic switch valve 51 disposed at the steam outlet port; a first electrical connection terminal assembly 13 and a second electrical connection terminal assembly 43, the first electrical connection terminal assembly 13 being disposed in the steam outlet port 12, and the second electrical connection terminal assembly 43 being disposed in the cleaning head accessory 4, wherein the first electrical connection terminal assembly 13 is connected to the electromagnetic switch valve 51 via a first wiring harness 14, thereby forming a first detection circuit between the electromagnetic switch valve 51 and the cleaning head accessory 4.

[0063] The first detection circuit forms a loop between the first electrical connection terminal assembly 13 of the steam outlet port 12 and the second electrical connection terminal assembly 43 of the cleaning head accessory 4 to detect whether the accessory is correctly installed. If it is not connected or has poor contact, the solenoid switch valve 51 remains closed to prevent steam leakage.

[0064] Optionally, in a preferred configuration, a steam detection sensor 52 is also included. A steam detection port 21 is provided on the top of the steam boiler assembly 2, and the steam detection sensor 52 is installed at the steam detection port 21. The steam detection sensor 52 is connected to the electromagnetic switch valve 51 via a second wiring harness 521, forming a second detection circuit between the electromagnetic switch valve 51 and the steam detection sensor 52. The second detection circuit involves the steam detection sensor 52 on the top of the steam boiler monitoring steam parameters in real time. When insufficient steam pressure is detected (e.g., incomplete vaporization of cold water), the control system can delay opening the electromagnetic valve to ensure a stable output of high-temperature steam.

[0065] Optionally, in a preferred configuration, a temperature sensor 53 is also included, which is disposed at the bottom of the steam boiler assembly 2. The temperature sensor 53 is connected to the solenoid valve 51 via a third wiring harness 531, forming a third detection circuit between the solenoid valve 51 and the temperature sensor 53. The third detection circuit uses the bottom temperature sensor 53 to monitor the boiler water level. When the water level is too low, causing the heating element to dry-burn, the temperature sensor 53 triggers a signal to close the solenoid valve and cut off the heating power supply, preventing equipment damage.

[0066] In summary, it is important to emphasize that when the device is first turned on, the solenoid valve will not open if the data from any of the first, second, or third detection circuits does not meet the requirements. This is to prevent the steam from carrying liquid water and thus avoid safety risks.

[0067] In a preferred embodiment, a pressure sensor 7 is further included. The pressure sensor 7 includes a detection end 71 and a display end 72. A pressure detection port 23 is provided on the top of the steam boiler assembly 2. The detection end 71 of the pressure sensor 7 is installed at the pressure detection port 23, and the display end 72 of the pressure sensor 7 protrudes outside the steam housing 1. By adding an independent pressure sensor 7, the pressure status monitoring and visualization of the steam boiler assembly 2 are enhanced based on the original steam detection sensor 52. Users can promptly detect problems through observation, thereby improving operational safety.

[0068] In a preferred embodiment, a temperature control display 6 is further included. The temperature control display 6 is connected in series between the temperature detection sensor 53 and the solenoid valve 51, and the temperature control display 6 has at least a high-temperature indicator 61 and a low-temperature indicator 62. This design of the temperature control display 6 integrates temperature status visualization with safety interlock control functions, not only improving the user experience of the device but also strengthening the temperature control logic of the third detection circuit by connecting it in series between the temperature detection sensor 53 and the solenoid valve 51.

[0069] In a preferred embodiment, an integrated power supply interface 54 is further included on the steam housing 1. This integrated power supply interface 54 is electrically connected to the electromagnetic switch valve 51, the steam detection sensor 52, and the temperature detection sensor 53 via internal cables, and is also electrically connected to an external power source via an external cable 541. This unified power supply architecture, where the integrated power supply interface 54 integrates the power supply requirements of the electromagnetic switch valve 51, sensors, and control circuits, and provides unified power from an external power source, reduces internal wiring complexity and improves system reliability. Preferably, a DC-DC converter module can be used to power the sensors, and combined with a sleep mode (e.g., shutting down unnecessary circuits when idle), standby power consumption can be reduced, meeting energy efficiency standards.

[0070] 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.

[0071] 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.
