Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning equipment, and in particular, to a cleaning head and a cleaning device. Background Technology
[0002] As people's living standards continue to improve, their requirements for their living and working environments are also increasing. To ensure environmental cleanliness, cleaning equipment has emerged to clean various places and objects. The use of cleaning equipment not only reduces labor costs for cleaning work but also improves its efficiency.
[0003] Cleaning equipment requires corresponding cleaning heads to achieve its cleaning function. Some cleaning heads have two parallel pipes: one is a water supply pipe for spraying cleaning solution onto the surface to be cleaned, and the other is a suction pipe for drawing dust, impurities, and dirty solution into the machine body. The suction pipe protrudes outwards relative to the water supply pipe, ensuring sufficient space for the nozzle at the front of the water supply pipe to spray the cleaning solution onto the surface. Generally, to achieve a more aesthetically pleasing overall design, the cleaning head is constructed as a single piece, completely enclosing the side space at the front of the water supply pipe. However, this makes it difficult to mold the cavity formed at the front of the water supply pipe, resulting in higher manufacturing difficulty. Summary of the Invention
[0004] In view of this, this application provides a cleaning head and a cleaning device, which aims to solve the problem of difficult manufacturing of cleaning heads.
[0005] On one hand, this application provides a cleaning head for connection to the body of a cleaning device. The cleaning head includes: a suction pipe, one end of which is a connection interface for connecting to the body, and the other end is a suction port; a water supply pipe, which is integrally formed with the suction pipe and arranged along the width direction of the cleaning head; a nozzle, which is connected to the water supply pipe and is located at one end of the water supply pipe adjacent to the suction port; wherein, the surface in contact with the surface to be cleaned is defined as the suction port surface, and the suction port protrudes outward relative to the water outlet of the nozzle so that a spraying space for spraying cleaning solution is formed between the water outlet and the suction port surface; the cleaning head also includes a baffle, which extends from the end of the water supply pipe where the nozzle is located along the length direction of the cleaning head to the suction port surface to form a cavity that encloses the spraying space, and the cavity opens to the side away from the suction pipe.
[0006] As one possible implementation, the length of the cavity is L1 and the length of the cleaning head is L2, wherein L1 is not less than 1 / 2 of L2.
[0007] As one possible implementation, the size of L1 is 120~140mm.
[0008] As one possible implementation, the cleaning head is divided along its length into a flat section, a transition section, and a round tube section that are connected in sequence; wherein, a cavity is formed in the flat section, a water delivery pipe is formed in the transition section and the round tube section, and a suction pipe runs through the flat section, the transition section, and the round tube section.
[0009] As one possible implementation, the flat portion has opposing first and second surfaces along the thickness direction of the cleaning head; the baffle includes a first rib located on the first surface and a second rib located on the second surface, and the first rib, the second rib, and the sidewall of the suction pipe enclose and define a cavity.
[0010] As one possible implementation, the first and second surfaces are parallel to each other.
[0011] As one possible implementation, the transition section is constructed as an arc-shaped surface or an inclined surface.
[0012] As one possible implementation, there is an angle between the suction nozzle surface and the length direction of the cleaning head, with the angle being 30° to 90°.
[0013] As one possible implementation, the included angle is 45°.
[0014] On the other hand, this application provides a cleaning device, which includes: a body; any of the above-mentioned cleaning heads, wherein the cleaning head is connected to the body through its own connection interface. Beneficial effects
[0015] This application designs the cavity at the front end of the water supply pipe, which is surrounded by a baffle, into a side-open chamber. The cavity is no longer a completely closed chamber on the side, but a chamber that opens to the side away from the suction pipe. This makes it easier to mold the cleaning head with this chamber and reduces the manufacturing difficulty. Attached Figure Description

[0026] This document provides numerous specific details to offer a deep understanding of the overall structure, function, and purpose of the embodiments described and illustrated in the specification and figures. Well-known operations, components, and elements have not been described in detail to avoid making the description overly redundant. The reader will understand that the embodiments described and illustrated herein are non-limiting examples, and thus will recognize that the specific structural and functional details disclosed herein are representative and illustrative. Variations and changes may be made to these embodiments without departing from the scope of the claims.
[0027] This application provides a cleaning device. For example, the cleaning device provided by this application can be a vacuum cleaner, and more particularly, it can be a wet / dry vacuum cleaner. Of course, the cleaning device provided by this application is not limited to a vacuum cleaner. Generally speaking, the cleaning device provided by this application can be any type of device for cleaning surfaces or objects to be cleaned.
[0028] The cleaning equipment provided in this application can apply a cleaning solution to a surface or object to be cleaned, and collect the turbid solution mixed with dirt from the surface or object to be cleaned by suction to achieve the cleaning purpose.
[0029] In one specific embodiment of this application, the cleaning device includes a body and a cleaning head, wherein the cleaning head is connected to the body via its own connection interface 12.
[0030] like Figures 1-3As shown, this application also provides a cleaning head for connecting to the body of the aforementioned cleaning equipment. The cleaning head includes: a suction pipe 10, one end of which is a connection interface 12 for connecting to the body, and the other end is a suction port 11; a water supply pipe 20, which is integrally formed with the suction pipe 10 and arranged along the width direction of the cleaning head; and a nozzle 30, which is connected to the water supply pipe 20 and is located at one end of the water supply pipe 20 adjacent to the suction port 11. The surface of the suction port 11 that contacts the surface to be cleaned is defined as the suction port surface S. The suction port 11 protrudes outward relative to the water outlet 31 of the nozzle 30 so that a spraying space for spraying cleaning solution is formed between the water outlet 31 and the suction port surface S. The cleaning head also includes a baffle 40, which extends from the end of the water supply pipe 20 where the nozzle 30 is located along the length direction of the cleaning head to the suction port surface S to form a cavity 21 that encloses the spraying space. The cavity 21 is open to the side away from the suction pipe 10.
[0031] See also Figure 2 The nozzle 30 of this application has a water outlet 31, the diameter of which can be set to be small. Thus, the nozzle 30 can spray a fine water jet to wash away dirt in the slit.
[0032] It is understandable that the length direction and width direction of the cleaning head are perpendicular to each other. The length direction and width direction together define a plane, and the thickness direction mentioned below is perpendicular to this plane. That is, the length direction, width direction and thickness direction are mutually perpendicular to each other.
[0033] In one specific embodiment of this application, the cleaning head is a one-piece structure, namely, the suction pipe 10, the water supply pipe 20, and the baffle 40 are integrally constructed. By designing the cavity 21 at the front end of the water supply pipe 20, which is surrounded by the baffle 40, as a side-open chamber, the cavity 21 is no longer a completely closed chamber on the side, but a chamber open to the side away from the suction pipe 10. This ensures that the cleaning head with this chamber is easier to mold and reduces manufacturing difficulty.
[0034] In another specific embodiment of this application, the baffle 40 can be detachably connected to the water supply pipe 20.
[0035] See also Figure 3 In this application, the length of the cavity 21 is L1, and the length of the cleaning head is L2, wherein L1 is not less than 1 / 2 of L2.
[0036] The length of the cleaning head is the sum of the length of the cavity 21 and the length of the water supply pipe 20. The higher the proportion of the length of the cavity 21, the shorter the length of the water supply pipe 20, which can save the material of the water supply pipe 20 and reduce the manufacturing cost.
[0037] Specifically, the size of L1 is 120~140mm.
[0038] The length of the cavity 21 determines the spraying distance of the nozzle 30. A longer spraying distance may cause the spraying point to deviate from the expected position due to gravity during the spraying process. A shorter spraying distance requires increasing the length of the water supply pipe 20, which increases costs. Therefore, when the length of the cavity 21 is 120~140mm, the spraying distance of the nozzle 30 can be kept within a reasonable range.
[0039] See also Figure 1 and Figure 3 In this application, the cleaning head is divided along its length into a flat portion 13, a transition portion 14 and a round tube portion 15 connected in sequence; wherein, a cavity 21 is formed in the flat portion 13, a water delivery pipe 20 is formed in the transition portion 14 and the round tube portion 15, and a suction pipe 10 passes through the flat portion 13, the transition portion 14 and the round tube portion 15.
[0040] In one specific embodiment of this application, the transition portion 14 is constructed as an arc-shaped curved surface or an inclined surface.
[0041] It is understandable that one end of the cleaning head is flat and the other end is cylindrical, with the two ends transitioning through an arc-shaped or sloping surface. The cleaning head can also be called a flat suction head or a flat suction head.
[0042] In one specific embodiment of this application, the flat portion 13 has opposing first and second surfaces along the thickness direction of the cleaning head; the baffle 40 includes a first rib located on the first surface and a second rib located on the second surface, and the first rib, the second rib, and the sidewall of the suction pipe 10 enclose and define a cavity 21.
[0043] By setting the first and second ribs, the cleaning solution sprayed from the outlet 31 can be prevented from splashing out of the suction range of the suction port 11 to the opposite sides of the thickness direction of the cleaning head, thus avoiding incomplete suction in one go.
[0044] Specifically, the first surface and the second surface are parallel to each other.
[0045] like Figure 4 As shown in a specific embodiment of this application, there is an angle θ between the suction nozzle surface S and the length direction of the cleaning head, where the angle θ is 30° to 90°. Specifically, the angle θ can be 45°.
[0046] It should be understood that the term "comprising" and its variations as used in this application are open-ended, meaning "including but not limited to". The term "according to" means "at least in part according to". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least another embodiment".
[0047] It should be understood that although terms such as “first” or “second” may be used in this application to describe various elements (such as a first surface and a second surface), these elements are not defined by these terms, which are only used to distinguish one element from another.
[0048] The scope of protection of this application is not limited to the above embodiments. Any variations or substitutions that can be conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
