Description

Technical Field

[0001] This utility model relates to the field of floor scrubber technology, and in particular to a cleaning head housing assembly and a cleaning head. Background Technology

[0002] Vacuum cleaners rely on electricity and generate negative pressure to suck up trash and dust from the floor. Classified by cleaning methods and the flow path of small and large debris, this type of technology is generally categorized as airflow / dust circulation technology. However, due to the limitations of its working principle, vacuum cleaners cannot clean some stubborn dirt and stains that are firmly attached to the floor. Therefore, a new type of floor cleaner, the "water-dust circulation" scrubber, has emerged. This scrubber uses a motor to drive a cleaning cylinder to wipe the floor, and it is also equipped with a water supply system and a water tank to clean the cleaning cylinder, thus achieving a perfect cleaning of the floor.

[0003] Chinese invention patent CN212326298U discloses a cleaning tool, which includes a cleaning head. The cleaning head includes: a cleaning module comprising a roller and a squeezing roller positioned above the right side of the roller, wherein the right side of the roller is the area to be cleaned, i.e., the squeezing roller is positioned above the surface of the area to be cleaned; the squeezing roller interferes with the roller, forming a water tank; a housing, including a side housing, has a first wastewater box; the roller and squeezing roller are respectively mounted on the side housing, the first wastewater box is connected to the water tank, and the first wastewater box contains a filter screen and a brush, the brush being used to clean debris from the surface of the filter screen. The bottom end of the squeezing roller interferes with the sponge layer of the roller, i.e., the bottom end of the squeezing roller squeezes the sponge layer, and the squeezing roller and roller form a water tank. A roller brush is located between the roller and the waste box, used to clean debris from the surface of the roller. Through "water and dust circulation," the roller can achieve self-cleaning and can continuously scrub the surface of the area to be cleaned.

[0004] The existing cleaning head housing assembly has low space utilization. The wastewater holding chamber is directly connected to the outer wiping layer of the cleaning roller, which causes the outer wiping layer of the cleaning roller to contain too much water and causes the water to slosh in the wastewater holding chamber, affecting the user experience.

[0023] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "rear," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] 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.

[0026] Example 1 This utility model embodiment provides a cleaning head housing assembly 110, see reference 110. Figures 1-7 as well as Figure 12 , Figure 13 As shown, it includes a cleaning head housing body 110a; The cleaning head housing body 110a has a left side wall 110a1 and a right side wall 110a2; a cleaning roller drive motor 10A can be fixed between the left side wall 110a1 and the right side wall 110a2, and the cleaning roller drive motor 10A is fitted with a cleaning roller outer wiping layer 10B. The cleaning head housing body 110a has a sewage chamber M and a dry waste chamber N that are divided into upper and lower sections; The sewage cavity M is equipped with a water guide tip 110a7 and a sewage overflow prevention plate 110a8; The water guide tip 110a7 is arc-shaped and interferes with the outer wiping layer 10B of the cleaning roller. The sewage overflow plate 110a8 is vertically set, and a sewage guide and collection area S is formed between the water guide tip 110a7 and the sewage overflow plate 110a8. The waste container N can be horizontally inserted into the waste box assembly 140.

[0027] The dry waste container N is specifically designed to collect dry or lightweight waste such as hair, dust, and paper scraps. It is designed as a horizontally insertable waste box assembly 140, which is easy to remove and empty, avoiding the problem of adhesion and clumping after contact with liquid.

[0028] In this embodiment of the invention, reference is made to Figure 12 and Figure 13 As shown, the cleaning head housing 110a is divided into a wastewater chamber M and a dry waste chamber N. The dry waste chamber N is specifically for collecting dry or lightweight waste such as hair, dust, and paper scraps. The wastewater chamber M is specifically for collecting liquid wastewater, thus achieving functional specialization. A waste container assembly 140 can also be inserted laterally into the dry waste chamber N for easy removal and emptying, avoiding the problem of adhesion and clumping after contact with liquid.

[0029] In this embodiment of the invention, reference is made to Figures 1-7 as well as Figure 12 , Figure 13 As shown, the arc-shaped design of the water guide tip 110a7 allows for close interference (i.e., slight contact or very close clearance fit) with the outer wiping layer 10B of the high-speed rotating cleaning roller. This interference produces two effects: first, scraping, efficiently removing excess water from the wiping layer like a scraper; and second, sealing, forming a liquid seal interface to prevent water from being carried out by the wiping layer or splashing into unwanted areas. The scraped liquid water, guided by the arc shape of the water guide tip 110a7, is precisely directed into the wastewater diversion and collection area S formed between it and the wastewater overflow prevention plate 110a8.

[0030] The cleaning head housing assembly 110 provided in this embodiment of the utility model effectively removes excess water through the water guide tip 110a7, so that the outer wiping layer 10B of the cleaning roller always maintains a suitable dry and wet state, which not only ensures its wiping effect on the ground, but also avoids the situation where it becomes "muddy and watery" due to excessive wetness, which would pollute the ground.

[0031] The cleaning head housing assembly 110 provided in this embodiment of the utility model refers to... Figures 1-7 as well as Figure 12 , Figure 13 As shown, the system comprises a wastewater chamber M and a dry waste chamber N, separated by upper and lower compartments. This layered structural design allows for the parallel arrangement of these two functional chambers within the limited space of the cleaning head 10, significantly improving space utilization. Furthermore, the wet-dry separation design fundamentally solves the problems of dry waste becoming moldy, smelly, and difficult to clean after being soaked in wastewater, maintaining hygiene inside the collection chamber and simplifying subsequent waste disposal processes.

[0032] The cleaning head housing assembly 110 provided in this embodiment of the utility model has a vertically arranged sewage overflow plate 110a8 that acts as a baffle. It restricts the water flow range in the collection area and separates it from other parts of the sewage chamber M to a certain extent. This greatly suppresses the sloshing of sewage in the chamber, avoids the "banging" sound of water during the cleaning process and the feeling of unstable equipment operation caused by water sloshing, and improves the quality and quietness of the product.

[0033] In an optional implementation, refer to Figures 12-15 As shown, the cleaning head housing body 110a is provided with a clean water inlet 110a5 and a clean water outlet 110a6; the clean water pipe adapter 110g is connected to the clean water inlet 110a5 and can be connected to the water pump 40A of the cleaning head 10 via pipeline; the clean water inlet 110a5 is connected to the clean water outlet 110a6; the clean water outlet 110a6 is connected to the sewage diversion and collection area S.

[0034] In an optional implementation, refer to Figures 1-7 As shown, the cleaning head housing assembly 110 also includes a passive squeezing roller 110c; the passive squeezing roller 110c is disposed between the left side wall 110a1 and the right side wall 110a2 of the cleaning head housing; the passive squeezing roller 110c interferes with the outer wiping layer 10B of the cleaning roller. The high-speed rotating outer wiping layer 10B of the cleaning roller not only passes through the water guide tip, but the arc-shaped edge of the water guide tip scrapes it, removing most of the liquid water adhering to the surface and shallow layer of the wiping layer, and uses its arc-shaped structure to guide the scraped water flow to the sewage diversion and collection area. Due to the interference between the passive squeezing roller 110c and the outer wiping layer 10B of the cleaning roller, a pressing point is formed between them. When the outer wiping layer 10B of the cleaning roller passes through this narrow pressing point, it is subjected to the mechanical squeezing action of the passive squeezing roller. This physical pressure can effectively squeeze out the water hidden deep in the pores of the wiping layer material, thereby improving the dryness of the outer wiping layer 10B of the cleaning roller and eliminating water stains.

[0035] In an optional implementation, refer to Figures 1-8 As shown, a left sliding latching block 110d1 for the squeeze roller is fixed to the left side wall 110a1 of the cleaning head housing; a right sliding latching block 110d2 for the squeeze roller is fixed to the right side wall 110a2 of the cleaning head housing; and a passive squeeze roller 110c is disposed between the left sliding latching block 110d1 and the right sliding latching block 110d2 of the squeeze roller.

[0036] In an optional embodiment, the cleaning head housing body 110a is provided with a first fixing seat 110a3 and a second fixing seat 110a4 for connecting the water tank of the cleaning head 10. The first fixing seat 110a3 and the second fixing seat 110a4 can be fixedly connected to the first connecting seat 120a3 and the second connecting seat 120a4 respectively, thereby realizing a fixed connection between the water tank body 120a and the cleaning head housing body 110a in the horizontal direction, ensuring a stable connection.

[0037] In an optional embodiment, the cleaning head housing assembly 110 further includes a cleaning roller end wear ring 110e fixed to the left side wall 110a1 of the cleaning head housing; the cleaning roller end wear ring 110e is sleeved on the end of the cleaning roller drive motor 10A so that the cleaning roller drive motor 10A can rotate relative to the cleaning roller end wear ring 110e, thereby preventing loosening caused by wear of parts.

[0038] In an optional embodiment, the cleaning head housing assembly 110 further includes a left decorative sticker 110p attached to the outside of the left side wall 110a1 of the cleaning head housing and a right decorative sticker 110q attached to the outside of the right side wall 110a2 of the cleaning head housing.

[0039] In an optional embodiment, the cleaning head housing assembly 110 further includes a detachable shovel assembly 110b; the detachable shovel assembly 110b is disposed at the lower end of the cleaning head housing body 110a and interferes with the outer wiping layer 10B of the cleaning roller, and can shovel up the garbage on the ground and enter the dry garbage cavity N along with the outer wiping layer 10B of the cleaning roller, thereby improving the efficiency of ground cleaning.

[0040] In an optional embodiment, the cleaning head housing assembly 110 further includes a cleaning head housing cover 110f that covers the top of the cleaning head housing body 110a.

[0041] Example 2 Based on the same inventive concept, this utility model embodiment also provides a cleaning head 10, see reference. Figures 8-11 As shown, it includes a water tank assembly 120, a hinge head locking cover assembly 130, and a cleaning head housing assembly 110 as described in Embodiment 1. A hinge head assembly 40, a connecting rod assembly 20, and a handle assembly 30 are sequentially arranged above the cleaning head 10.
