Abstract
Description
Technical Field
[0001] The present disclosure relates to a cleaning head and a pet cleaning system. Background Art
[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.
[0003] Cats, dogs and other pets often need to take care of their hair during the breeding process, especially for pets with long and thick hair. If the pet's hair is not taken care of in time, the pet's hair will become tangled or curled.
[0004] A large amount of hair is lost during grooming, placing a significant burden on pet owners. To collect this lost hair and reduce the burden on pet owners, pet brushes used in conjunction with vacuum cleaners are currently available. These hairs are collected by the negative pressure of the vacuum cleaner and stored in the dust collection chamber of the vacuum cleaner.
[0005] However, this pet brush cannot adjust the airflow of the vacuum cleaner when in use. Once the suction force of the vacuum cleaner is too strong, it may cause discomfort to the pet during the pet combing process. In addition, the pet brush will also be adsorbed on the pet's skin, increasing the user's combing resistance. Utility Model Content

[0063] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.
[0064] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0065] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.
[0066] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.
[0067] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may 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 purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.
[0068] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially 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 accompanying drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be positioned "above" the other component or feature. Thus, the exemplary term "below" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.
[0069] The terms used herein are for the purpose of describing specific embodiments and are not intended to be restrictive. As used herein, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, the features, integral bodies, steps, operations, parts, assemblies and / or their groups stated are explained, but the presence or addition of one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups is not excluded. It should also be noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values and / or the values provided that will be recognized by those of ordinary skill in the art.
[0070] Figure 1 It is a schematic structural diagram of a cleaning head according to one embodiment of the present disclosure. Figure 2 It is a schematic structural diagram of a cleaning head according to an embodiment of the present disclosure from another angle. Figure 3 It is a schematic cross-sectional structural diagram of a cleaning head according to one embodiment of the present disclosure.
[0071] like Figures 1 to 3 As shown, the cleaning head of the present disclosure may include components such as a housing assembly 100 , a bracket 200 , a combing needle assembly 300 , and an air duct member 400 .
[0072] Figure 4 Schematic diagram of the structure of a housing assembly according to one embodiment of the present disclosure.
[0073] like Figure 4As shown, the housing assembly 100 can be formed by combining multiple parts. In a specific embodiment, the housing assembly 100 can include a first housing 110, a second housing 120, and a third housing 130. The first housing 110 has a generally tapered profile and a hollow interior. The upper and lower ends of the first housing 110 are both open. 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 member 400, and the shape of the upper end of the first housing 110 can be adapted to the shape of the button 600.
[0074] A hole-like structure 111 is formed on the sidewall of the first housing 110. The second housing 120 is fixedly connected to the first housing 110. In a preferred embodiment, the second housing 120 may include a cylindrical portion through which the connecting tube 500 can pass. The third housing 130 is generally cylindrical, and one end thereof is connected to the cylindrical portion of the second housing 120. Thus, the connecting tube 500 can pass through the third housing 130 and the second housing 120, as well as through the hole-like structure 111 of the first housing 110, and connect to the bracket 200.
[0075] In the present disclosure, the housing assembly 100 has an air inlet 101. In a preferred embodiment, the air inlet 101 is formed on the second housing 120. Specifically, the air inlet 101 can be implemented as a plurality of elongated holes, which can be arranged in parallel. As a result, the air inlet 101 of the housing assembly 100 of the present disclosure is not directed toward the user or pet, reducing the impact on the user and pet.
[0076] Figure 5 Schematic diagram of the structure of a bracket according to one embodiment of the present disclosure.
[0077] like Figure 3 and Figure 5 As shown, the bracket 200 of the present disclosure is disposed on the housing assembly 100 and is located within the cavity structure of the housing assembly 100. Specifically, the upper end of the bracket 200 can be fixedly connected to the upper end of the first housing 110 of the housing assembly 100 by fasteners such as screws.
[0078] A accommodating space is provided inside the bracket 200, and the upper and lower ends of the bracket 200 are both open, so that the button 600 can be connected to the air duct member 400 through the opening at the upper end of the bracket 200, and at least part of the air duct member 400 can be inserted into the interior of the bracket 200 through the opening at the lower end of the bracket 200.
[0079] The bracket 200 is provided with a first opening 210 , which communicates with the accommodating space so that gas can flow to the air leakage port 412 of the air duct member 400 through the air inlet 101 of the housing and the first opening 210 of the bracket 200 .
[0080] like Figure 5 As shown, the first opening 210 can be provided near the upper end of the bracket 200. Of course, the first opening 210 can also be provided at other suitable positions.
[0081] The bracket 200 is provided with a second opening 220, and the exhaust port 411 of the air duct member 400 is connected to the connecting pipe 500 via the second opening 220. Specifically, an annular member 230 is provided on the outer wall of the bracket 200. The annular member 230 is arranged around the second opening 220, and the connecting pipe 500 can be fixedly connected to the annular member 230, so that gas can flow into the connecting pipe 500 through the second opening 220 and be discharged from the connecting pipe 500.
[0082] The bracket 200 includes two substantially parallel side walls, so as to guide the movement of the air duct member 400 through the two substantially parallel side walls of the bracket 200; Figure 3 In the direction shown, the two side walls may be two side walls in the left and right directions, whereby the duct member 400 can be guided by the two side walls to move up and down.
[0083] Refer again Figure 3 The other side walls of the bracket 200 can be set at an angle, so that the cross-sectional area of the accommodating space of the bracket 200 can gradually increase from top to bottom, thereby facilitating the installation of the air duct member 400 and controlling the movement of the air duct member 400.
[0084] In a preferred embodiment, the first opening 210 can be close to one of the two parallel walls, and the second opening 220 can be disposed on the other of the two parallel walls.
[0085] The combing needle assembly 300 is disposed on the housing assembly 100. Specifically, the combing needle assembly 300 is indirectly disposed on the housing assembly 100 by being directly fixed to the bracket 200. In other words, the position of the combing needle assembly 300 relative to the housing assembly 100 does not change.
[0086] like Figure 2 and Figure 3 As shown, the combing needle assembly 300 of the present invention includes a needle plate 310 and a combing needle component 320 installed on the needle plate 310, wherein the needle plate 310 is fixed to the bracket 200, one end of the combing needle component 320 is fixed to the needle plate 310, and the other end of the combing needle component 320 can extend to below the lower end of the shell assembly 100, and can extend or retract relative to the combing needle hole 422 of the air duct component 400.
[0087] Figure 6Schematic diagram of the structure of an air duct component according to one embodiment of the present disclosure. Figure 7 2 is a schematic structural diagram of an air duct component according to an embodiment of the present disclosure from another angle.
[0088] like Figure 6 and Figure 7 As shown, the air duct member 400 of the present disclosure is configured to be movable between a first position and a second position relative to the housing assembly 100; specifically, Figure 3 In the direction shown, the duct member 400 can be operated to generate vertical movement.
[0089] Structurally, the duct member 400 disclosed herein may include an air guide component 410 and a base plate 420 connected to the air guide component 410. Those skilled in the art should understand that while the present disclosure describes the duct member 400 with two technical features (the air guide component 410 and the base plate 420), this does not necessarily mean that the duct member 400 is assembled from discrete components. In a preferred embodiment, the duct member 400 may be integrally formed from a material such as plastic.
[0090] The air guide member 410 of the duct member 400 can be inserted into the interior of the bracket 300 through the opening at the lower end of the bracket 300. In addition, the duct member 400 can be guided by the bracket 300 and move in the up and down directions.
[0091] For example, a button 600 may be provided at the upper end of the duct member 400. When a downward force is applied to the button 600, the duct member 400 may be moved downward from the first position to the second position. Then, the duct member 400 may be moved upward from the second position to the first position under the restoring force of some elastic restoring elements.
[0092] When the duct member 400 moves vertically, the bottom plate 420 can also move vertically. In a specific embodiment, when the duct member 400 is in the first position, the bottom plate 420 can be located within the opening at the lower end of the housing assembly 100. Then, when the 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 duct member 400 is in the second position, the distance between the bottom plate 420 and the housing assembly 100 is maximized.
[0093] In a specific structure, such as Figure 2 and Figure 8As shown, a suction port 421 and a combing pin hole 422 are formed on the bottom plate 420. The suction port 421 is formed as an elongated hole and is approximately located in the middle area 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 connected to the interior of the air guide component 410. The air guide component 410 is formed with an exhaust port 411, so that an air flow path is formed inside the air duct member 400 from the suction port 421 to the exhaust port 411.
[0094] The combing pin holes 422 are configured as a plurality of elongated holes, which can be arranged in parallel. In a preferred embodiment, the combing pin holes 422 are provided on both sides of the length direction of the suction port 421, and the length direction of the combing pin holes 422 can be approximately perpendicular to the length direction of the suction port 421.
[0095] The present disclosure provides a plurality of combing needle components 320, wherein each of the elongated holes of the combing needle holes 422 is provided with at least one combing needle component 320; thus, when the air duct member 400 moves from the first position to the second position, the length of the combing needle component 320 exposed below the bottom plate 420 gradually decreases, and this process is the retraction of the combing needle component 320 relative to the air duct member 400. In other words, when the air duct member 400 is in the first position, the combing needle components 320 of the combing needle assembly 300 at least partially extend outside the air duct member 400, and when the air duct member 400 is in the second position, the combing needle components 320 of the combing needle assembly 300 retract relative to the air duct member 400.
[0096] In an extreme case, that is, when the air duct member 400 is in the second position, the lower end of the combing needle component 320 is not exposed from the bottom plate 420, and the combing needle component 320 can be completely retracted.
[0097] like Figure 6 and Figure 7 As shown, the duct member 400 includes an air leakage port 412; when the duct member 400 is in a first position, the gas provides a first flow rate of gas to the gas flow path of the duct member 400 via the air inlet 101 and the air leakage port 412; when the duct member 400 is in a second position, the gas provides a second flow rate of gas to the duct member 400 via the air inlet 101 and the air leakage port 412; the first flow rate is greater than the second flow rate.
[0098] Therefore, when the cleaning head of the present disclosure is in use, that is, when using the cleaning head to clean a pet's hair, the air duct member 400 can be controlled to the first position, at which point the combing needle member 320 can be exposed at its maximum length from the bottom plate 420. When the user holds the cleaning head and moves it over the pet's body, the pet's hair can be combed. Moreover, because the first flow rate of gas can be provided to the gas flow path, the flow rate of gas entering the gas flow path through the suction port 421 will be reduced (compared to when the air duct member 400 is in the second position) under the premise of the same suction power. Therefore, when the cleaning head of the present disclosure is moved over the pet's body surface, it has a smaller combing resistance, which can improve the pet's comfort.
[0099] Furthermore, when the cleaning head is removed from the pet, the user can press button 600, causing the duct member 400 to move from the first position to the second position. Since the duct member 400 and the combing needle component 320 can move relative to each other, the pet hair retained on the combing needle component 320 will be separated from the combing needle component 320. Furthermore, in this state, the flow rate of gas entering the gas flow path through the suction port 421 is increased (compared to when the duct member 400 is in the first position). The hair separated from the combing needle component 320 is then sucked into the pet cleaning system through the suction port 421. Consequently, when using the cleaning head of the present disclosure to clean a pet, less hair falls to the ground, resulting in a better cleaning effect.
[0100] In general, the suction force of the cleaning head disclosed herein can be adjusted during use, thereby improving the comfort of the pet.
[0101] In a preferred embodiment, the button 600 can be secured to the duct member 400 via a snap-fit structure. Furthermore, when the duct member 400 is in the first position, the upper surface of the button 600 can be slightly higher than the upper end of the first housing 110 of the housing assembly 100. When the duct member 400 is in the second position, the upper surface of the button 600 can be slightly lower than the upper end of the first housing 110 of the housing assembly 100. This arrangement of the button 600 makes it easier for a user to press the button 600 with their thumb while holding the cleaning head in one hand, causing the duct member 400 to move downward.
[0102] In a preferred embodiment, the air leakage port 412 of the air duct member 400 is formed in the air guide component 410. More preferably, the air leakage port 412 is formed in the side wall of the air guide component 410 and is arranged near the upper end of the air guide component 410.
[0103] Specifically, the air guide component 410 also has two generally parallel sidewalls (i.e., two opposing sidewalls), and the two generally parallel sidewalls of the air guide component 410 can be arranged in a one-to-one correspondence with the two generally parallel sidewalls of the bracket 200. Furthermore, the air leakage port 412 is formed in one of the two generally parallel sidewalls of the air guide component 410, and the exhaust port 411 is formed in the other of the two generally parallel sidewalls of the air guide component 410. In other words, the air leakage port 412 and the exhaust port 411 are respectively formed in the two opposing sidewalls of the air guide component 410.
[0104] In the present disclosure, in one embodiment, the first opening 210 is formed on one of the two parallel side walls of the bracket 200. In this case, the air leakage port 412 of the air guide component 410 has substantially the same shape as the first opening 210 located on the bracket 200; and the exhaust port 411 of the air guide component 410 has substantially the same shape as the second opening 220 located on the bracket 200. Thus, when the duct member 400 is in the first position, the air leakage port 412 can be aligned with the first opening 210. In this case, the exhaust port 411 of the air guide component 410 can be aligned with or not aligned with the second opening 220 of the bracket 200. Preferably, the exhaust port 411 of the air guide component 410 is not aligned with (offset from) the second opening of the bracket 200. As a result, the amount of gas entering the gas flow path through the suction port 421 is small, and accordingly, the cleaning head has a smaller suction force.
[0105] When the air duct part 400 is in the second position, the air leakage port 412 and the first opening portion 210 can be arranged in an asymmetrical (offset) manner. Accordingly, the flow rate of gas entering the gas flow path through the air leakage port 412 is small or even zero, that is, the gas cannot enter the gas flow path through the air leakage port 412. At this time, the amount of gas entering the gas flow path through the suction port 421 is large, and accordingly, the cleaning head has a greater suction force.
[0106] In addition, when the air duct member 400 is in the second position, the exhaust port 411 of the air guide member 410 and the second opening portion 220 of the bracket 200 can be aligned or not, and preferably, the exhaust port 411 of the air guide member 410 and the second opening portion 220 of the bracket 200 are aligned, thereby enabling the cleaning head to have greater suction force.
[0107] In a preferred embodiment, Figure 3As shown, the cleaning head of the present disclosure may further include a blocking member 700, which is fixed relative to the housing assembly 100. When the air duct member 400 moves from the first position to the second position, the area of the air leakage opening 412 of the air guide component 410 blocked by the blocking member 700 gradually increases. In a specific embodiment, the blocking member 700 can be fixed to the bracket 200.
[0108] In other words, when the duct member 400 is in the first position, the blocking member 700 is at least partially offset from the air leakage port 412, allowing external air to enter the air flow path through the air leakage port 412, thereby reducing the suction force of the suction port 421 on the bottom plate 420. Furthermore, when the duct member 400 is in the second position, the blocking member 700 is aligned with the air leakage port 412 and blocks the air leakage port 412 of the air guide component 410, reducing the second flow rate to zero. In other words, the blocking member 700 completely blocks the air guide component 410 and allows air to enter the air flow path entirely through the suction port 421, thereby increasing the suction force of the suction port 421 and allowing pet hair scraped off the bottom plate 420 to be quickly drawn into the dust collection device of the vacuum cleaner.
[0109] In the present disclosure, the blocking member 700 is made of a flexible material. In a specific embodiment, the flexible material can be an elastic material such as rubber or silicone, so that the blocking member 700 does not affect the movement of the air duct member 400 and has good sealing performance.
[0110] Figure 9 4 is a schematic structural diagram of an air duct component according to another embodiment of the present disclosure.
[0111] like Figure 9 As shown, in another embodiment, the base plate 420 further includes a long strip-shaped flow guide structure 423 open toward the side of the base plate 420, and the flow guide structure 423 is connected to the suction port 421 so that the gas can flow to the suction port 421 through the flow guide structure 423, and further reduce the flow rate of the gas flowing to the gas flow path through the suction port 421 (the amount of gas flowing to the suction port 421 in the vertical direction).
[0112] In addition, an opening is provided on the housing assembly 100 at a position corresponding to the flow guiding structure 423 , and gas can flow to the flow guiding structure 423 through the opening, thereby further reducing the suction force at the suction port 421 .
[0113] In the present disclosure, the edge of the bottom plate 420 is provided with a flange portion 430, which is located adjacent to the inner surface of the housing assembly 100. Preferably, the flange portion 430 is located between the inner surface of the housing assembly 100 and the outer surface of the bracket 200. The flange portion 430 has a predetermined height, which is set so that when the duct member 400 is in the second position, the upper end of the flange portion 430 is higher than the lower edge of the housing assembly 100. In other words, when the duct member 400 of the present disclosure is in motion, no gap is formed between the duct member 400 and the housing assembly 100, thereby preventing dust and the like from easily entering the interior of the housing assembly 100.
[0114] According to another aspect of the present disclosure, a pet cleaning system is provided, which may include the cleaning head and a vacuum cleaner. Specifically, the connecting pipe 500 of the cleaning head can be connected to the suction pipe of the vacuum cleaner, thereby sucking the pet's shed hair and storing it in the vacuum cleaner.
