Description

TECHNICAL FIELD

[0001] The present disclosure relates to a cleaning head and a pet cleaning system. BACKGROUND

[0002] During the process of raising pets such as cats and dogs, the pet's hair needs to be groomed frequently, especially for pets with long or thick hair. If the pet's hair is not groomed in time, the pet's hair will be knotted or rolled.

[0003] A large amount of hair will fall off during the grooming process, which will bring a great burden to the pet owner. In order to collect these fallen hairs and reduce the burden of the pet owner in grooming, pet brushes that are used in cooperation with a vacuum cleaner exist in the prior art. Accordingly, these hairs are collected by the negative pressure of the vacuum cleaner and stored in the dust collection chamber of the vacuum cleaner.

[0004] However, when using such a pet brush, the air flow of the vacuum cleaner cannot be adjusted. Once the suction force of the vacuum cleaner is too large, it may cause discomfort to the pet during the grooming process. Moreover, the pet brush will also be attracted to the pet's skin, increasing the user's grooming resistance. CONTENT OF THE INVENTION

[0075] The present disclosure will be further described in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only intended to explain the related content, and not to limit the present disclosure. In addition, it should be noted that, for the convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0076] It should be noted that the embodiments and features of the embodiments in the present disclosure can be combined with each other in the case of no conflict. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0077] Unless otherwise specified, the example embodiments / instances shown will be understood as providing exemplary features of various details that can implement the technical concepts of the present disclosure in practice. Therefore, unless otherwise specified, the features of various embodiments / instances can be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of the present disclosure.

[0078] In the drawings, cross-hatching and / or shading are generally used to indicate that a portion of one feature can be located structurally close to another, even though not directly visible. As such, unless stated otherwise, the presence of cross-hatching or shading is not meant to imply that a specific material, material property, dimension, ratio, etc., is being represented other than that which might be explicitly stated. In addition, for purposes of clarity and / or description, the dimensions and / or relative dimensions made in the drawings can not be drawn to scale and / or to scale with respect to one another. When example embodiments can be implemented differently, a specific process sequence can be performed in a different order than described. For example, two consecutively described processes can be performed substantially simultaneously or in reverse order to that described. In addition, the same reference numbers represent the same components.

[0079] When a component is referred to as being "on" or "over" another component, "connected to" or "coupled to" another component, it can be directly on, directly connected to, or directly coupled to the other component, or intervening components can be present. However, when a component is referred to as being "directly on", "directly connected to", or "directly coupled to" another component, there are no intervening components present. For this reason, the term "connected" can refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0080] For descriptive purposes, the present disclosure can use spatial or relative terms, such as "below," "lower," "below," "low," "above," "upper," "on," "higher," and "side" (e.g., as in "sidewall") to describe the relative relationship between one element and another element as illustrated in the figures. The spatial or relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "under" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. Moreover, the device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatial or relative descriptors used herein interpreted accordingly.

[0081] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the terms "including," "includes," "having," "has," "with," or "contains," or variants thereof are used in either the detailed description and / or the claims, such terms are intended to be inclusive in a manner similar to the term "comprising" as an open transition term without precluding any additional or other elements.

[0082] Figure 1 is a structural schematic view of a cleaning head according to an embodiment of the present disclosure. Figure 2 is a structural schematic view of another angle of a cleaning head according to an embodiment of the present disclosure. Figure 3 is a structural schematic view of a cross-section of a cleaning head according to an embodiment of the present disclosure.

[0083] As Figures 1 to 3 shown, the cleaning head of the present disclosure can include a housing assembly 100, an inner housing assembly 200, a bristle assembly 300, an air duct 400, and a gas releasing member 800, etc.

[0084] Figure 4 is a structural schematic view of a housing assembly according to an embodiment of the present disclosure.

[0085] As Figure 4As shown, the housing assembly 100 can be formed by combining multiple parts. In one specific embodiment, the housing assembly 100 can include a first housing 110 and a second housing 120; the first housing 110 generally has a conical profile and its interior forms a hollow structure. The upper end and the lower end of the first housing 110 are both open, wherein the shape of the lower end of the first housing 110 can be adapted to the shape of the bottom plate 420 of the air duct 400, and the shape of the upper end of the first housing 110 can be adapted to the shape of the adjustment button 600.

[0086] The sidewall of the first housing 110 forms a hole structure 111. The second housing 120 is fixedly connected with the first housing 110. In one preferred embodiment, the second housing 120 can include a cylindrical portion which can be used for connecting the pipe 500 to pass through. In other words, the pipe 500 can pass through the second housing 120, and then pass through the hole structure 111 of the first housing 110, and be connected to the inner housing assembly 200.

[0087] In the present disclosure, the housing assembly 100 has an air inlet 101, which, in one preferred embodiment, is formed on the first housing 110, and of course, can also be formed on the second housing 120. Specifically, the air inlet 101 can be implemented by a plurality of long strip-shaped holes which can be arranged in parallel. Thus, the air inlet 101 of the housing assembly 100 of the present disclosure does not face the user and the pet, thereby reducing the impact on the user and the pet.

[0088] Figure 5 is a structural schematic diagram of an inner housing assembly according to one embodiment of the present disclosure.

[0089] As shown in Figure 3 and Figure 5 , the inner housing assembly 200 of the present disclosure is arranged in the housing assembly 100 and located in the hollow structure of the housing assembly 100. Specifically, the upper end of the inner housing assembly 200 can be fixedly connected with the upper end of the first housing 110 of the housing assembly 100 by screws or other fasteners.

[0090] The inner housing assembly 200 is internally provided with an accommodation space, and at least part of the air duct 400 is slidably arranged in the accommodation space. Specifically, the upper end and the lower end of the inner housing assembly 200 are both open, whereby the adjustment button 600 can be located in the opening of the upper end of the housing assembly 100 and can move relative to the housing assembly 100, whereby the adjustment button 600 can adjust the position of the air duct 400 and make the air duct 400 move between the first position and the second position.

[0091] In one specific embodiment, the adjustment button 600 is connected to the air duct 400 through the air release member 800; in other words, the air release member 800 of the present disclosure is arranged between the adjustment button 600 and the air duct 400, and at least a portion of the air duct 400 can be inserted into the interior of the inner housing assembly 200 via the opening of the lower end of the inner housing assembly 200.

[0092] Overall, the adjustment button 600 of the present disclosure is located at the top end of the air duct 400, and the adjustment button 600, the air release member 800 and the air duct 400 move synchronously.

[0093] As shown in Figure 3 and Figure 5 , the inner housing assembly 200 is provided with an opening portion 220, and the exhaust port 411 of the air duct 400 is connected to the connecting pipe 500 via the opening portion 220. Specifically, the outer wall surface of the inner housing assembly 200 is provided with an annular member 230, which is arranged around the opening portion 220, and the connecting pipe 500 can be fixedly connected with the annular member 230, so that the gas can flow to the connecting pipe 500 via the opening portion 220 and be discharged from the connecting pipe 500.

[0094] The inner housing assembly 200 includes two substantially parallel side walls to guide the movement of the air duct 400 through the two substantially parallel side walls of the inner housing assembly 200.

[0095] The comb needle assembly 300 is arranged in the outer housing assembly 100; specifically, the comb needle assembly 300 is indirectly arranged in the outer housing assembly 100 by being directly fixed to the inner housing assembly 200. In other words, the position of the comb needle assembly 300 of the present disclosure relative to the outer housing assembly 100 does not change.

[0096] As shown in Figure 2 and Figure 3 , the comb needle assembly 300 of the present disclosure includes a needle plate 310 and a comb needle component 320 mounted to the needle plate 310, wherein the needle plate 310 is fixed to the inner housing assembly 200, one end of the comb needle component 320 is fixed to the needle plate 310, and the other end of the comb needle component 320 can be extended below the lower end of the outer housing assembly 100 and can be extended or retracted relative to the comb needle hole 422 of the air duct 400.

[0097] Figure 6 is a structural schematic view of an air duct according to one embodiment of the present disclosure. Figure 7 is a schematic view of the connection relationship between the air duct and the air release member according to one embodiment of the present disclosure.

[0098] As shown in Figure 6 and Figure 7As shown, the air duct member 400 of the present disclosure is arranged to be movable relative to the housing assembly 100 between a first position and a second position; in particular, as shown in the direction indicated by the arrow, the air duct member 400 is operable to produce a vertical movement. Figure 3 As shown, the air duct member 400 of the present disclosure is arranged to be movable relative to the housing assembly 100 between a first position and a second position; in particular, as shown in the direction indicated by the arrow, the air duct member 400 is operable to produce a vertical movement.

[0099] Structurally, the air duct member 400 of the present disclosure can include an air guide part 410 and a bottom plate 420 connected to the air guide part 410; it should be understood by those skilled in the art that although the air duct member 400 is described in terms of two technical features (the air guide part 410 and the bottom plate 420), this does not necessarily mean that the air duct member 400 is obtained by assembling separate components. In a preferred embodiment, the air duct member 400 can be integrally formed from a material such as plastic.

[0100] The air guide part 410 of the air duct member 400 can be inserted into the interior of the inner housing assembly 300 via the opening at the lower end of the inner housing assembly 300. Moreover, the air duct member 400 can be guided by the inner housing assembly 300 and produce a vertical movement.

[0101] For example, the upper end of the air duct member 400 can be connected to the adjustment button 600 via the air release member 800, and when a downward force is applied to the adjustment button 600, the air duct member 400 can be caused to move downward to move from the first position to the second position. Then, the air duct member 400 can move upward under the restoring force of some elastic restoring elements to move from the second position to the first position.

[0102] When the air duct member 400 moves in the vertical direction, the bottom plate 420 can also produce a vertical movement. In a specific embodiment, when the air duct member 400 is in the first position, the bottom plate 420 can be located in the opening at the lower end of the housing assembly 100, and then when the air duct member 400 is controlled and moves downward, the bottom plate 420 can be spaced apart from the lower end of the housing assembly 100. In particular, when the air duct member 400 is in the second position, the spacing between the bottom plate 420 and the housing assembly 100 is maximized.

[0103] In a specific structure, as shown in Figure 2 and Figure 8 As shown, the bottom plate 420 is formed with a suction port 421 and a card needle hole 422, the suction port 421 is formed as a long strip-shaped hole and is located substantially in the middle region of the bottom plate 420; in a preferred embodiment, the length direction of the suction port 421 can be the same as the length direction of the bottom plate 420. The suction port 421 is in communication with the interior of the air guide part 410, and the air guide part 410 is formed with an exhaust port 411 to form a gas flow path from the suction port 421 to the exhaust port 411 in the interior of the air duct member 400.

[0104] The comb hole 422 is arranged as a plurality of long strip-shaped holes which can be arranged in parallel. In a preferred embodiment, the comb hole 422 is arranged on both sides of the length direction of the suction port 421, and the length direction of the comb hole 422 can be substantially perpendicular to the length direction of the suction port 421.

[0105] The comb part 320 of the present disclosure is arranged as a plurality of comb parts, wherein at least one comb part 320 is arranged in each long strip-shaped hole of the comb hole 422; thereby, the length of the comb part 320 exposed below the bottom plate 420 gradually decreases during the movement of the air duct piece 400 from the first position to the second position, that is, the retraction of the comb part 320 relative to the air duct piece 400. In other words, when the air duct piece 400 is in the first position, the comb part 320 of the comb assembly 300 is at least partially extended to the outside of the air duct piece 400, and when the air duct piece 400 is in the second position, the comb part 320 of the comb assembly 300 is retracted relative to the air duct piece 400.

[0106] In an extreme case, that is, when the air duct piece 400 is in the second position, the lower end of the comb part 320 is not exposed from the bottom plate 420, at which time the comb part 320 can be completely retracted.

[0107] As shown in Figure 6 and Figure 7 The air duct piece 400 includes a gas leakage port 412, thereby forming a gas flow path from the gas leakage port 412 to the exhaust port 411 inside the air duct piece 400. The air duct piece 400 includes an air leakage port formed thereon, which is in communication with the gas flow path of the air duct piece 400, wherein when the air duct piece 400 is in the first position, a first flow rate of gas is provided to the air duct piece 400 via the air leakage port, and when the air duct piece 400 is in the second position, a second flow rate of gas is provided to the air duct piece 400 via the air leakage port, the first flow rate being greater than the second flow rate.

[0108] Specifically, when the air duct piece 400 is in the first position, a first flow rate of gas is provided to the gas flow path of the air duct piece 400 via the air inlet 101, the air leakage port, and the gas leakage port 412; when the air duct piece 400 is in the second position, a second flow rate of gas is provided to the air duct piece 400 via the air inlet 101, the air leakage port, and the gas leakage port 412; the first flow rate being greater than the second flow rate.

[0109] Thus, when the cleaning head of the present disclosure is in use, i.e. when the cleaning head is used to clean the pet's hair, the air duct 400 can be controlled to be in the first position, at which time the comb needle component 320 can be exposed to the maximum length from the bottom plate 420. When the user holds the cleaning head to move on the pet's body, the pet's hair can be combed; and since the first flow of gas can be provided to the gas flow path, accordingly, under the premise of the same suction power, the flow of gas entering the gas flow path via the suction port 421 will be smaller (compared to when the air duct 400 is in the second position), thus, the cleaning head of the present disclosure has a smaller hair combing resistance when moving on the pet's body surface, which can improve the comfort of the pet.

[0110] In addition, when the cleaning head is away from the pet, the user can press the adjustment button 600, at which time the air duct 400 will move from the first position to the second position. Since the air duct 400 and the comb needle component 320 can move relative to each other, at this time the pet's hair held on the comb needle component 320 will be separated from the comb needle component 320. Moreover, in this state, the flow of gas entering the gas flow path via the suction port 421 will be larger (compared to when the air duct 400 is in the first position), and these hairs separated from the comb needle component 320 will be sucked via the suction port 421 to the pet cleaning system, thus, during the use of the cleaning head of the present disclosure to clean the pet, less hair falls to the ground, and the use effect is better.

[0111] Overall, the cleaning head of the present disclosure can adjust the suction force when in use, which can improve the comfort of the pet.

[0112] In a preferred embodiment, when the air duct 400 is in the first position, the upper surface of the adjustment button 600 can be slightly higher than the upper end of the first shell 110 of the housing assembly 100; when the air duct 400 is in the second position, the upper surface of the adjustment button 600 can be slightly lower than the upper end of the first shell 110 of the housing assembly 100. By thus setting the adjustment button 600, the user can press the adjustment button 600 with the thumb under the condition of holding the cleaning head with one hand, and make the air duct 400 move downward.

[0113] The air guide component 410 also has two substantially parallel side walls (i.e. two opposite side walls), and the two substantially parallel side walls of the air guide component 410 and the two substantially parallel side walls of the inner housing assembly 200 can be one-to-one correspondingly arranged. In a preferred embodiment, the air leakage port 412 is formed at the top end of the air guide component 410, and after the gas flows through the air outlet of the air release component 800 and the air leakage port 412 of the air guide component 410, it flows to the gas flow path.

[0114] Figure 8 is a structural schematic diagram of an inner housing assembly according to an embodiment of the present disclosure.Figure 9 is a schematic view of the cooperation relationship between the inner housing assembly and the air release member according to an embodiment of the present disclosure. Figure 10 is a schematic view of the cooperation relationship between the inner housing assembly, the air release member and the adjustment button according to an embodiment of the present disclosure. Figure 11 is another angle schematic view of the cooperation relationship between the inner housing assembly, the air release member and the adjustment button according to an embodiment of the present disclosure.

[0115] As shown in Figures 8 to 11 , based on the above structure, in the process that the air duct member 400 moves from the first position to the second position, at least part of the air release member 800 gradually moves to the inside of the inner housing assembly 200 via the upper end opening of the inner housing assembly 200. Thus, in the process that the air duct member 400 moves from the first position to the second position, the upper end of the inner housing assembly 200 at least partially covers the air release opening, and the second flow rate gradually decreases.

[0116] In other words, as the air duct member 400 moves from the first position to the second position, the overlapping area between the inner housing assembly 200 and the air release member 800 also becomes larger and larger, that is, the upper end of the inner housing assembly 200 at least partially covers the air release opening, accordingly, it becomes more and more difficult for the gas to enter the air duct member 400 through the air release member 800, and thus the second flow rate can gradually decrease.

[0117] In a preferred embodiment, when the air duct member 400 is located at the second position, the air release member 800 blocks the upper end opening of the inner housing assembly 200, so that the second flow rate is 0.

[0118] Figure 12 is a schematic view of the structure of the air release member according to an embodiment of the present disclosure.

[0119] As shown in Figure 12 , the air release member 800 of the present disclosure includes structures such as a limiting member 810 and a baffle 820. Among them, the limiting member 810 is connected with the upper end of the air duct member 400; the baffle 820 is connected with the limiting member 810 through a connecting member 830, wherein the baffle 820 and the limiting member 810 are spaced apart from each other, and an air release opening is formed between them. That is to say, the connecting member 830 in the air release member 800 of the present disclosure is provided as a plurality of connecting members 830, at this time, two adjacent connecting members 830, limiting members 810 and baffles 820 jointly define an air release opening, and thus the air release opening of the air release member 800 of the present disclosure is also a plurality of air release openings.

[0120] Thus, in the cleaning head of the present disclosure, through the provision of the air release member 800, the structure and working principle are obviously different from those of the prior art.

[0121] In one preferred embodiment, the inner surface of the inner housing assembly 200 is formed with a first limiting boss 240 for limiting the position of the deflation member 800 so that the air duct member 400 is located at the second position. That is, when the adjustment button 600 is moving downwardly, the limiting member 810 of the deflation member 800 can be in pressure contact with the first limiting boss 240, at this time, the adjustment button 600 will not be able to move further downwardly, thereby the air duct member 400 can be located at the second position.

[0122] Similarly, the outer housing assembly 100 is formed with a second limiting boss 140 for limiting the position of the deflation member 800 so that the air duct member 400 is located at the first position. That is, when the adjustment button 600 is moving upwardly, the baffle 820 of the deflation member 800 can be in pressure contact with the second limiting boss 140, at this time, the adjustment button 600 will not be able to move further upwardly, thereby the air duct member 400 can be located at the first position. Wherein, in the first position, the baffle 820 is away from the upper end opening of the inner housing assembly 200; in the second position, the baffle 820 is close to the upper end opening of the inner housing assembly 200. In one preferred embodiment, in the second position, the baffle 820 abuts against the upper end of the inner housing assembly 200 to block the upper end opening.

[0123] Figure 13 is a structural schematic view of an air duct member according to another embodiment of the present disclosure.

[0124] As Figure 13 shown, in another embodiment, the bottom plate 420 further comprises a long strip-shaped flow guide structure 423 open towards the side of the bottom plate 420, which is arranged in communication with the suction port 421 so that the gas can flow to the suction port 421 via the flow guide structure 423, and further reduce the flow rate (the amount of gas flowing to the suction port 421 in the vertical direction) of the gas flowing to the gas flow path via the suction port 421.

[0125] In addition, the outer housing assembly 100 is provided with an opening at a position corresponding to the flow guide structure 423, and the gas can flow to the flow guide structure 423 via the opening, thereby further reducing the suction force at the suction port 421.

[0126] In the present disclosure, the edge of the bottom plate 420 is provided with a turned-up portion 430, which is arranged adjacent to the inner surface of the housing assembly 100. Preferably, the turned-up portion 430 is arranged between the inner surface of the housing assembly 100 and the outer surface of the inner housing assembly 200. The turned-up portion 430 has a preset height, which is arranged such that the upper end of the turned-up portion 430 is higher than the lower edge of the housing assembly 100 when the air duct 400 is in the second position, that is, during the movement of the air duct 400 of the present disclosure, no gap is generated between the air duct 400 and the housing assembly 100, so that dust and the like are not easy to enter the inside of the housing assembly 100.

[0127] According to another aspect of the present disclosure, a pet cleaning system can include the cleaning head described above and a vacuum cleaner. Specifically, the connecting pipe 500 of the cleaning head can be connected to the suction duct of the vacuum cleaner, so as to suck and save the pet hair that falls off in the vacuum cleaner.
