[0001] This utility model relates to the field of cleaning tools, and in particular to a portable cleaning device. Background Technology

[0002] With the increasing demand for health, hygiene, convenience, and efficiency in modern society, a portable cleaning device (hereinafter referred to as the cleaning device) suitable for personal or pet use has emerged to meet market demand. However, after market research and studying user feedback, the inventors found that existing cleaning devices have the following problems: 1. Existing cleaning devices have limited functionality. When a complete cleaning process (rinsing, sterilization, and drying) needs to be completed, users need to use multiple cleaning devices alternately, resulting in cumbersome operation and low efficiency. In addition, if users need to complete the above cleaning process in scenarios such as outdoor travel, they need to carry multiple cleaning devices, which also makes it inconvenient for users to move around outdoors; 2. Existing water-rinsing cleaning devices rely on water as the cleaning medium. While lacking sterilization and disinfection capabilities, they can also cause secondary pollution to the cleaned object due to the quality of the water used (such as poor water quality caused by a harsh water source environment, resulting in water containing more impurities and bacteria), bringing potential hygiene and health risks.

Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] Reference Figures 1 to 3 This utility model provides a portable cleaning device, which includes a housing 100, a suction component 200, a fan component 300, and an electrolysis component 400.

[0037] The housing 100 is provided with an air cavity 121, a water cavity 111, an air inlet 122, an air outlet 123, and a water supply pipe 500. The air inlet 122 and the air outlet 123 are both connected to the air cavity 121. The suction component 200 is provided in the housing 100 and is connected to the water supply pipe 500. The suction component 200 is connected to the water cavity 111 and can drive the water in the water cavity 111 to be output to the outside through the water supply pipe 500. The fan component 300 is provided in the air cavity 121 and can drive the air to flow through the air inlet 122 and the air cavity 121 in sequence and then be sent out through the air outlet 123. The electrolysis component 400 is provided in the water cavity 111 and can electrolyze the water in the water cavity 111 to produce bactericidal substances. The suction unit 200 is configured as a water pump and has a pipe 210 located in the water cavity 111 to communicate with the water cavity 111; the electrolysis unit 400 is configured as a titanium-based noble metal oxide coated electrode, which can be a titanium-plated ruthenium electrode.

[0038] It is understood that the electrolytic element 400, with its titanium-based noble metal oxide coated electrode, can selectively electrolyze water to generate ozone, hydroxyl radicals, or hydrogen, depending on the electrolysis conditions, thus enabling sterilization, disinfection, and deodorization. Specifically, some embodiments may be as follows: when the electrolytic element 400 operates continuously for 60 seconds at a 5V DC voltage and 1A current, it primarily generates ozone; if the voltage is increased to 7.5V and maintained for 90 seconds, it primarily generates hydroxyl radicals; if it operates for a long time at a low voltage (3V), it can generate hydrogen. The selected water (i.e., the water contained in the water chamber 111) is general municipal tap water (pH approximately 7.0, conductivity 200–400 μS / cm); of course, the above parameters can be fine-tuned according to actual conditions.

[0039] It is understandable that the bactericidal substances produced by electrolysis can be used to sterilize and disinfect the objects being cleaned when the water is discharged.

[0040] It is understood that the fan component 300 of this application is configured as a high-efficiency micro fan with a powerful blowing function. Specifically, it can be configured as a brushless DC fan (12V, speed 18000rpm). The fan speed can reach 12 meters per second, which can accelerate the drying speed of the part after rinsing and effectively blow away dust and particles on the object being cleaned.

[0041] On the one hand, the portable cleaning device of this application integrates an electrolysis unit 400, a suction unit 200, and a fan unit 300 into one unit. Users only need to operate this portable cleaning device to complete the cleaning process of rinsing, sterilization, and drying. The specific process is as follows: 1. The suction unit 200 drives the water in the water chamber 111 to flow through the water pipe 500 for rinsing, while the electrolysis unit 400 electrolyzes the water in real time to generate bactericidal substances (such as ozone, hydroxyl radicals, hydrogen, etc.) so that rinsing and sterilization are completed simultaneously; 2. After rinsing, the fan unit 300 is activated to generate a high-speed airflow from the air chamber 121 and blow dry the water from the air outlet 123. Therefore, users do not need to use other cleaning devices alternately; they can complete the entire cleaning process by operating only this portable cleaning device. Thus, it can simplify the cleaning operation and improve the cleaning efficiency. In addition, if users need to complete the above cleaning process in scenarios such as outdoor travel, they only need to carry this portable cleaning device, which is convenient for users to move around outdoors.

[0042] On the other hand, the electrolysis unit 400 provided in the water cavity 111 can electrolyze the water source water in the water cavity 111 in real time, so as to generate bactericidal substances to sterilize and disinfect the water source water first, thus greatly reducing or eliminating the situation of secondary pollution to the cleaning object caused by the quality of the water used.

[0043] In some embodiments, the electrolytic element 400 may be configured as an iridium dioxide electrode, a titanium-plated ruthenium anode plate, etc., capable of electrolyzing water to generate ozone.

[0044] In this embodiment, refer to Figure 1 and Figure 2 The housing 100 includes a connected handheld part 110 and a head unit 120. An air chamber 121, an air inlet 122, an air outlet 123, a water pipe 500, and a fan 300 are all located in the head unit 120. A water chamber 111, a suction device 200, and an electrolysis device 400 are all located in the handheld part 110. The handheld part 110 is for the user to hold, carry, and operate; the handheld part 110 has a receiving cavity 113 for placing the suction device 200.

[0045] With the above structure, the heavier modules such as the water cavity 111 (including water storage) and the electrolysis component 400 are located in the handheld part 110, while the lightweight air and water circuit modules (including the air cavity 121, air inlet 122, air outlet 123, water supply pipe 500, and fan component 300) are located in the head 120. This allows the center of gravity of the whole machine to be lowered and closer to the gripping point of the handheld part 110, so as to provide users with a better gripping and operating experience.

[0046] In this embodiment, refer to Figure 1 and Figure 2The air outlet 123 has a circular structure and is designed with a diameter of 40mm and an air outlet angle of approximately 25°, which is a diffused type, so that the air volume can meet the needs of rapid drying in local areas.

[0047] In some embodiments, the diameter and air outlet angle of the circular air outlet 123 can be set according to actual needs, such as a diameter of 50mm and an air outlet angle of about 30° for a diffusion type, etc.

[0048] In some embodiments, the air outlet 123 can be configured as an elliptical structure, a flat structure, or the like to adapt to different cleaning scenarios.

[0049] In this embodiment, refer to Figure 2 and Figure 3 The water supply pipe 500 is located in the air cavity 121, and the water outlet end of the water supply pipe 500 is inserted into the air outlet 123.

[0050] With the above structure, the water pipe 500 is placed in the air cavity 121, and part of the space in the air cavity 121 can be used to accommodate the water channel, thereby creating space reuse and improving the compactness of the equipment integration.

[0051] In some embodiments, the water supply pipe 500 may be independently located on the outside of the machine head 120.

[0052] In this embodiment, refer to Figures 1 to 3 The water outlet end of the water supply pipe 500 is detachably provided with a functional nozzle 600, wherein the suction member 200 can drive the water in the water chamber 111 to pass through the water supply pipe 500 and the functional nozzle 600 in sequence and then be output to the outside.

[0053] With the above structure, users can replace the functional nozzle 600 with the corresponding effect according to the actual cleaning scenario to adapt to a variety of cleaning objects.

[0054] In some embodiments, the functional nozzle 600 may be configured as a nozzle capable of atomizing water output. Specifically, the nozzle capable of atomizing water output may be made of medical-grade polypropylene (PP) or polycarbonate (PC), and its water outlet front end is provided with a porous ceramic filter element (pore size of about 0.1~0.3 mm) to obtain a microchannel design so that water can be physically atomized after passing through.

[0055] In some embodiments, the functional nozzle 600 may be configured as an extension tube nozzle capable of extending into and cleaning specific areas (such as crevices on the surface of an animal's body). Specifically, the extension tube nozzle may be made of a flexible silicone tube (approximately 15 cm in length and 5 mm in outer diameter). It is understood that the extension tube nozzle can deform and bend to avoid obstacles and cooperate with insertion and movement to clean areas that are difficult to clean.

[0056] In some embodiments, in order to enrich the water rinsing methods of the portable cleaning device, the suction member 200 is connected to the air cavity 121, and the suction member 200 can transport water in the water cavity 111 to the air cavity 121, so that the water is output to the outside with the air flow in the air cavity 121.

[0057] In this embodiment, refer to Figure 2 and Figure 3 The water supply pipe 500 is equipped with a heating element 700, which is located on the outside of the water supply pipe 500 and in the air cavity 121. The heating element 700 can heat the water flowing through the water supply pipe 500 and can heat the air flowing through the air cavity 121.

[0058] Through the above structure, the above settings can realize dual-path reuse of thermal energy. Specifically, when rinsing the object to be cleaned with water, the heating element 700 can heat the water flowing through the water pipe 500 to improve the contact comfort of the object to be cleaned and to increase the water temperature to enhance the degreasing effect. When drying the object to be cleaned with air, the same heating element 700 can heat the air flowing through the air chamber 121 to greatly improve the air drying efficiency of the object to be cleaned.

[0059] In some embodiments, the heating element 700 is disposed inside the water pipe 500.

[0060] In this embodiment, refer to Figure 1 The handheld unit 110 is equipped with a control unit 800. The DC power supply, fan unit 300, heating unit 700, and electrolysis unit 400 are all electrically connected to the control unit 800. The control unit 800 can control the operation of the suction unit 200, fan unit 300, heating unit 700, and electrolysis unit 400. The control unit 800 can be configured as a microcontroller module with control buttons.

[0061] Understandably, users can operate the corresponding components by pressing the control buttons on the control unit 800 to put the portable cleaning device of this application into the corresponding mode. The specific modes are: 1. Single air blowing mode with only the fan unit 300 working; 2. Hot air blowing mode with the fan unit 300 and the heating unit 700 working together; 3. Single water spray mode with only the suction unit 200 working; 4. Hot water spray mode with the suction unit 200 and the heating unit 700 working together (the suction unit 200 is turned on first, and the heating unit 700 is turned on after 1 second); 5. Single water spray sterilization and disinfection mode with the suction unit 200 and the electrolysis unit 400 working together; 6. Hot water spray sterilization and disinfection mode with the suction unit 200, the electrolysis unit 400 and the heating unit 700 working together (the suction unit 200 and the electrolysis unit 400 are turned on simultaneously first, and the heating unit 700 is turned on after 0.5 seconds); 7. Pre-sterilization and disinfection mode for the water in the water chamber 111 with only the electrolysis unit 400 working.

[0062] Understandably, the controller 800, which is configured as a microcontroller module, is equipped with a timer and a power controller to facilitate precise control.

[0063] Understandably, the heating element 700 located on the outside of the water pipe 500 can be a stainless steel-clad PTC ceramic heating module. A silicone insulation layer (1.5mm thick) can be wrapped around the heating element 700 to reduce or prevent burns caused by accidental contact. The control unit 800 can be equipped with a temperature sensor corresponding to the heating element 700. When the temperature sensor detects that the temperature of the heating element 700 reaches 65°C or higher, it will feed the temperature information back to the control unit 800, causing the control unit 800 to stop the heating element 700. Furthermore, the control unit 800, in conjunction with its temperature sensor, can also stably control the temperature of the heating element 700 within a preset range (e.g., 45~55°C).

[0064] In some embodiments, the control element 800 may be configured as a slide switch.

[0065] In this embodiment, refer to Figures 1 to 3 The accommodating cavity 113 is provided with a battery component 910, which is connected to a charging part 920 exposed to the outside. The suction component 200, the fan component 300, the heating component 700 and the electrolytic component 400 are all electrically connected to the battery component 910, and the battery component 910 can supply power to the suction component 200, the fan component 300 and the electrolytic component 400.

[0066] Understandably, the battery unit 910 can use an 18650 lithium battery pack (rated capacity 2200mAh, 3 series and 1 parallel), supporting 5V / 2A input charging. The charging unit 920 may be equipped with an overvoltage protection board to prevent overcharging and over-discharging of the battery unit 910. The housing 100 may be equipped with an indicator light electrically connected to the battery unit 910, which can flash when the battery unit 910's charge level is below 15% to remind the user to charge.

[0067] It is understood that the battery component 910 is electrically connected to the control component 800, thereby indirectly enabling the aforementioned suction component 200, fan component 300, heating component 700, and electrolytic component 400 to be electrically connected to the battery component 910. The user can control the battery component 910 to supply power to the corresponding components via the control component 800, thereby controlling the operation of the corresponding components.

[0068] With the above structure, the battery 910, which has the function of storing and supplying electricity, enables the portable cleaning device of this application to be used in outdoor scenarios without power.

[0069] In some embodiments, the handheld part 110 is provided with a power cord, which is electrically connected to the control unit 800 to indirectly achieve electrical connection with the suction unit 200, the fan unit 300, the heating unit 700 and the electrolysis unit 400. The power cord can be directly connected to the mains power to power the cleaning device.

[0070] In this embodiment, refer to Figure 1 The charging unit 920 is configured with a charging port, and the charging unit 920 can be connected to an external power source to charge the battery 910.

[0071] In some embodiments, the charging unit 920 may be configured as a charging plug.

[0072] In some embodiments, refer to Figure 4 The handheld part 110 is provided with a water inlet 112 communicating with the water chamber 111. The water inlet 112 can be connected to an external water source, allowing the external water source to supply water to the water chamber 111. When the water in the water chamber 111 is insufficient, the external water source can replenish the water chamber 111 through the water inlet 112. Furthermore, the external water source can supply water to the water chamber 111 through the water inlet 112 to achieve continuous water supply, ensuring that the rinsing operation of this cleaning device can be carried out uninterruptedly.

[0073] It is understandable that the water inlet 112 is connected to an external water source. Specifically, the handheld part 110 is provided with a threaded connector (1 / 4 thread size) corresponding to the water inlet 112. The external water source is fitted into the above-mentioned threaded connector through a pipe (such as a silicone hose).

[0074] Based on the above embodiments, a one-way valve may be provided at the water inlet 112 to prevent water in the water chamber 111 from flowing back through the water inlet 112.

[0075] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
