Description

Technical Field

[0001] This application belongs to the field of cleaning equipment technology, and specifically relates to a cleaning head and cleaning equipment. Background Technology

[0002] The working principle of a steam cleaner is to use high-temperature steam to accelerate the movement of dirt molecules, thereby breaking the binding force between them to remove various stubborn stains. At the same time, it completely eliminates various bacteria, mites, microorganisms and pathogens attached to objects.

[0003] Current steam cleaners' cleaning heads cannot self-clean after the brushes come into contact with dirt, requiring manual cleaning before the next cleaning cycle can begin. This significantly reduces cleaning efficiency and results in a poor user experience.

[0004] Therefore, how to overcome the above-mentioned technical defects is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0017] Optionally, the cleaning head includes two or more cleaning components or the cleaning components include two or more cleaning parts;

[0018] The two or more cleaning components are arranged side by side or at a preset angle, or the two or more cleaning parts are arranged side by side or at a preset angle. "Side by side" means that the center lines of the cleaning components are parallel to the center lines of the negative pressure ports, and "at a preset angle" means that the cross-sections containing the center lines of the cleaning components intersect after being extended.

[0019] Optionally, the cleaning component includes a first cleaning part and a second cleaning part, a portion of the first cleaning part being covered by a cleaning source ejected from the cleaning source nozzle, and the first cleaning part and the second cleaning part being respectively disposed on both sides of the negative pressure port.

[0034] As a third embodiment of this application, while at least a portion of the cleaning component is housed within the negative pressure port, at least a portion of the cleaning component can also be covered by the cleaning source ejected from the cleaning source nozzle.

[0035] It is understood that the third embodiment of this application incorporates the first and second embodiments. That is, when the cleaning head is cleaning dirt, some dirt on the cleaning component is washed away by the cleaning source sprayed from the cleaning source nozzle, and some dirt is directly sucked into the negative pressure port. Moreover, dirt washed off from the cleaning component is also sucked into the negative pressure port. It can be seen that the self-cleaning effect of the cleaning head disclosed in this embodiment is far greater than the self-cleaning effect of the above two embodiments.

[0036] Through testing, the above design method has been verified that 98%-100% of the dirt on the cleaning component can be removed, which basically achieves complete self-cleaning of the cleaning head, greatly extending the cleaning time of a single cleaning, thereby improving the user's experience.

[0045] In view of this, the core of this application is to provide a cleaning head that can extend the cleaning time of a single cleaning session and improve the user's experience.

[0046] Another core aspect of this application is to provide a cleaning device.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Please refer to [the provided text]. Figures 1 to 5 .

[0048] Please refer to Figure 1 The cleaning head disclosed in this application includes a housing 100 and a cleaning component 200, which is used to clean the object to be cleaned.

[0049] The housing 100 is provided with a cleaning source nozzle 101 and a negative pressure port 103. At least a portion of the cleaning component 200 is housed in the negative pressure port 103, and / or at least a portion of the cleaning component 200 is covered by the cleaning source sprayed from the cleaning source nozzle 101.

[0050] As a first embodiment of this application, at least a portion of the cleaning component 200 is housed within the negative pressure port 103. With this configuration, when the cleaning head is cleaning dirt, some of the dirt adhering to the cleaning head can be sucked into the negative pressure port 103, thereby achieving partial self-cleaning of the cleaning component 200. The cleaning source in this embodiment includes high-pressure water vapor.

[0051] Experimental verification shows that the above design allows 60%-70% of the dirt on the cleaning component 200 to be sucked in by the negative pressure port 103, which means that the cleaning head achieves self-cleaning to a certain extent, and also extends the cleaning time of the cleaning head for a single cleaning cycle to a certain extent.

[0052] In a second embodiment of this application, the cleaning source ejected from the cleaning source nozzle 101 is angled to rinse the cleaning portion of the cleaning component, meaning that at least a portion of the cleaning component 200 is configured to be covered by the cleaning source ejected from the cleaning source nozzle 101. With this configuration, the cleaning source ejected from the cleaning source nozzle 101 can wash away some of the dirt adhering to the cleaning component 200, thus achieving partial self-cleaning of the cleaning component 200. The cleaning source in this embodiment includes high-pressure steam, pressurized water, or a pressurized cleaning solution.

[0053] Experimental results show that the above design can wash away 70%-80% of the dirt on the cleaning component 200, meaning that the cleaning head achieves self-cleaning to a certain extent and also extends the cleaning time of the cleaning head per wash to a certain extent.

[0054] As a third embodiment of this application, please refer to... Figure 1 It is understood that while at least a portion of the cleaning component 200 is housed within the negative pressure port 103, at least a portion of the cleaning component 200 can also be covered by the cleaning source ejected from the cleaning source nozzle 101.

[0055] It is understood that the third embodiment of this application incorporates the first and second embodiments. That is, when the cleaning head is cleaning dirt, some dirt on the cleaning component 200 is washed away by the cleaning source sprayed from the cleaning source nozzle 101, and some dirt is sucked into the negative pressure port 103. Moreover, the dirt washed off from the cleaning component 200 is also sucked into the negative pressure port 103. It can be seen that the self-cleaning effect of the cleaning head disclosed in this embodiment is much greater than the self-cleaning effect of the above two embodiments.

[0056] Through testing, the above design method can remove 98%-100% of the dirt on the cleaning component 200, which basically achieves complete self-cleaning of the cleaning head, greatly extending the cleaning time of a single cleaning, thereby improving the user's experience.

[0057] It should be noted that the cleaning component 200 being housed in at least a portion within the negative pressure port 103 includes at least two implementations: one implementation is that the cleaning component 200 is a single scraper, wherein the single scraper is embedded within the negative pressure port 103; the other implementation is that the cleaning component 200 is a double scraper, wherein one of the double scrapers is embedded within the negative pressure port 103, or both scrapers are embedded within the negative pressure port 103.
