Description

Technical Field

[0001] This application relates to the field of pet cleaning small household appliances, and in particular to a spherical pet hair vacuum cleaner. Background Technology

[0002] With the increasing number of pet-owning families, daily cleaning of pet hair has become one of the core needs of pet owners. Pet hair vacuums, as targeted cleaning tools, are gradually becoming essential small household appliances because they can quickly remove hair from pets' bodies, clothes, sofas, pet beds, and other surfaces. Currently, pet hair vacuums on the market are mainly divided into handheld stick type, horizontal type, and small handheld portable type. Their core structure mostly consists of a handle and a suction unit. The suction unit integrates a fan, filter, and hair collection chamber. The fan generates negative pressure, drawing in air containing hair from the air inlet, filtering it through the filter, and expelling it from the air outlet, thus collecting the hair.

[0003] However, existing pet vacuum cleaners still have significant limitations in structural design and practical usability, making it difficult to meet the diverse cleaning needs of pet owners. Most existing products adopt a rectangular or long-handled shape. The long handle of handheld vacuum cleaners causes a shift in the center of gravity, easily leading to hand fatigue during prolonged use. Cuboid vacuum cleaners have sharp corners, which can easily cause stress to pets when cleaning them close to their bodies. Furthermore, they require a flat surface for support; if the table is tilted or cluttered, they are prone to tipping over, causing wear and tear on the outer shell, and even scattering internal hair. Consequently, the air inlet, fan, and outlet of existing products are often non-linear due to design limitations, with multiple bends in the airflow channel. This results in significant loss of negative pressure generated by the fan during transmission, making it difficult to effectively absorb hair near the edge of the air inlet.

[0004] In summary, the shortcomings of existing pet hair vacuums in terms of shape, airflow, and scene adaptability limit their cleaning efficiency and user experience. There is an urgent need for a new structural design that can balance grip comfort, placement stability, efficient suction, and flexible cleaning to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the aforementioned technical problems, this application provides a spherical pet hair vacuum cleaner.

[0006] This application provides a spherical pet hair remover, which adopts the following technical solution: A spherical pet hair remover includes a spherical shell, and an air inlet assembly, an adsorption unit, and an air outlet assembly are sequentially arranged inside the spherical shell along its axial direction. The air inlet assembly and the air outlet assembly are connected through the adsorption unit, and the three form an airflow channel.

[0007] By adopting the above technical solution and using a spherical shape as the basic form of the shell, a design without sharp edges can be achieved, avoiding the stress response caused by pets bumping into each other during cleaning. At the same time, the spherical structure is easier to hold, reducing hand fatigue after prolonged use, and also provides a stable framework for the coaxial arrangement of internal components.

[0008] Furthermore, the adsorption unit includes an annular fan housing and a fan. The fan housing is fixedly installed corresponding to the maximum cross-section of the spherical shell, and the fan housing is sealed to the inner wall of the shell through a mounting bracket. The fan is installed inside the fan housing. A filter screen is installed on the side of the fan housing facing the air inlet assembly. The spherical shell is divided into two openable hemispherical shells with its maximum cross-section as the parting surface. The mounting bracket is set at the parting surface so that the two hemispherical shells form a complete sphere when closed.

[0009] By adopting the above technical solution, the adsorption unit and the shell are sealed and fixed. The filter screen can intercept pet hair in the airflow and prevent it from entering the fan and affecting its operation. The cooperation between the hemispherical shell and the mounting bracket at the parting surface can quickly open and close the shell, which is convenient for internal cleaning and maintenance.

[0010] Furthermore, the air intake assembly includes an air intake housing and a control unit housing. The air intake housing is fixed inside one of the hemispheres of the spherical housing, and the edge of the air intake housing is fixedly connected to the mounting bracket. The interior of the air intake housing is hollow, forming an airflow cavity, which is connected to one side of the filter screen of the adsorption unit. A circular mounting groove is provided at the end of the air intake housing away from the adsorption unit, and the control unit housing is embedded in the mounting groove. The two are connected by multiple spokes evenly distributed along the circumference, and an air intake channel is formed between adjacent spokes. The air intake channel is connected to the airflow cavity. A clearance hole is provided on the spherical housing corresponding to the position of the control unit housing, so that the outer surface of the control unit housing protrudes outside the housing. The surface of the control unit housing is an arc surface adapted to the spherical housing, so that the control unit housing and the two hemispheres together form a complete spherical outline.

[0011] By adopting the above technical solution, a smooth airflow path from the air intake channel to the airflow chamber is constructed to ensure that hair enters efficiently with the airflow; the protruding design of the control unit shell facilitates operation, while the curved shape maintains the integrity of the overall spherical appearance and improves the grip.

[0012] Furthermore, the air inlet housing, the filter screen, and the control unit housing enclose a hair collection cavity, which is connected to the air inlet channel and the filter screen respectively, and is used to temporarily store the pet hair that has been filtered and trapped.

[0013] By adopting the above technical solution, hair can be temporarily stored in a centralized manner, preventing hair from spreading with the airflow or entering the fan. At the same time, the clear chamber structure allows subsequent cleaning to be performed only on the collection chamber, simplifying the process.

[0014] Furthermore, a control unit is installed inside the housing of the control unit. The control unit includes a switch button, a main control circuit board, and a status indicator light. The switch button is flush with the arc surface of the control unit housing and transitions smoothly with the arc surface. The status indicator light and the main control circuit board are placed inside the housing of the control unit. The main control circuit board is electrically connected to the fan, status indicator light, and switch button of the adsorption unit, respectively, and is used to control the start and stop of the fan and display the operating status.

[0015] By adopting the above technical solutions, convenient control of the start and stop of the fan and visual feedback of its operating status can be achieved. The smooth design of the switch buttons and curved surfaces avoids bumps that are uncomfortable to hold, while protecting the control components from external dust interference.

[0016] Furthermore, the air outlet assembly includes an air outlet, which is opened on the surface of the spherical shell and communicates with the interior of the fan housing; the central axis of the air outlet is offset from the axis of the parting surface of the spherical shell.

[0017] By adopting the above technical solutions, the filtered clean air is ensured to be discharged smoothly. The offset design of the air outlet can use the reaction force when the air is discharged to help adjust the posture of the hair vacuum cleaner during use and improve the stability of operation.

[0018] Furthermore, a power module is also provided inside the housing. The power module is fixed inside the hemispherical shell where the air outlet assembly is located, and its center of gravity is offset from the axis of the housing parting surface on the other side, and opposite to the offset direction of the air outlet. Through the offset of the center of gravity of the power module, the center of gravity of the lint remover is lower than the center of the shell, forming a self-righting effect to ensure that it stands stably when placed. The power module includes a rechargeable battery and a wireless charging coil. The rechargeable battery is electrically connected to the main control circuit board and the fan to supply power to them.

[0019] By adopting the above technical solution, the center of gravity shift is used to achieve a roly-poly effect, preventing the hair vacuum from tipping over when placed, which could cause wear on the outer shell or scattering of internal hair; the wireless charging function eliminates the need to plug and unplug cables, improving ease of use, while the rechargeable battery meets the needs of wireless use.

[0020] Furthermore, the outer surface of the spherical shell is covered with an elastic layer; the shell is also provided with an external interface.

[0021] By adopting the above technical solution, the elastic layer can enhance the anti-slip properties when gripping, and at the same time play a buffering role in the event of drops or collisions, protecting the internal components; the external interface can connect to accessories such as pet toys, expanding the entertainment function scenarios of the pet lint remover and improving the practicality of the product.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By combining a spherical shell with an elastic layer, the product achieves a non-sharp, bump-resistant, easy-to-grip, and fatigue-reducing effect. Combined with the power module's center of gravity offset design, it creates a self-righting effect, solving the problems of existing products being easy to tip over and easy to get tired when holding them, thus improving safety and stability. 2. By constructing a smooth airflow channel through the coaxial arrangement of the air inlet component, adsorption unit and air outlet component, negative pressure loss is reduced. Combined with the hair collection chamber and detachable filter, efficient adsorption and convenient cleaning are achieved, solving the problems of low adsorption efficiency and inconvenient cleaning of existing products. 3. It integrates wireless charging and external interfaces, which not only meets the convenience of wireless use, but also expands the entertainment function scenarios. It allows pets such as cats to suck up the loose hair that falls while playing. At the same time, the visual design of the control unit improves the ease of operation, and the overall experience of pet hair cleaning is improved. Attached Figure Description

[0025] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] This application discloses a spherical pet hair remover, as shown in the embodiments below. Figure 1-4 The device includes a spherical shell 1, inside which an air inlet assembly, an adsorption unit, and an air outlet assembly are arranged sequentially along its axial direction. The air inlet assembly and the air outlet assembly are connected through the adsorption unit, and the three together form an airflow channel. The shell 1 is spherical, which has the characteristics of being without sharp edges and easy to hold.

[0027] Reference Figure 1-4 , Figure 7-8 The adsorption unit includes a ring-shaped fan housing 32 and a fan, preferably a centrifugal fan 31. The fan housing 32 is fixedly installed corresponding to the maximum cross-section of the spherical shell 1. The fan housing 32 is sealed to the inner wall of the spherical shell 1 through a mounting bracket 33. The mounting bracket 33 has a ring structure, with its outer ring fixedly connected to the inner wall of the spherical shell 1 and its inner ring fixedly connected to the outer wall of the fan housing 32, thus achieving stable installation of the fan housing 32 within the spherical shell 1. The fan is installed in the internal cavity of the fan housing 32, with its air inlet facing the air inlet assembly and its air outlet 46 facing the air outlet assembly. A filter screen 321 is detachably installed on the side of the fan housing 32 facing the air inlet assembly. The filter screen 321 is preferably a sponge filter screen 321, used to filter pet hair in the air and prevent hair from entering the fan and affecting its normal operation.

[0028] Reference Figure 6 The spherical shell 1 is divided into two openable hemispherical shells 13, with its maximum cross-section as the parting surface. The shell 1 is spherically shaped. A mounting bracket 33 is positioned at the parting surface, allowing the two hemispherical shells 13 to form a complete sphere when closed. In this embodiment, the two hemispherical shells 13 are connected by screws. When it is necessary to clean pet hair from inside, simply loosen the screws to separate the two hemispherical shells 13; the operation is simple and quick.

[0029] Reference Figure 9-10 , Figure 13The air intake assembly includes an air intake housing 41 and a control unit housing 42. The air intake housing 41 is fixed inside one of the hemispherical shells 13 of the spherical housing 1, specifically located on the side away from the air outlet assembly. The edge of the air intake housing 41 is fixedly connected to the mounting bracket 33 to ensure a sealed connection between the air intake housing 41 and the mounting bracket 33. The interior of the air intake housing 41 is hollow, forming an airflow cavity 411. The airflow cavity 411 communicates with one side of the filter screen 321 of the adsorption unit, forming an airflow channel for airflow.

[0030] Reference Figure 5 , Figure 9 and Figure 10 The air inlet housing 41 has a circular mounting groove at the end furthest from the adsorption unit. The control unit housing 42 is fitted into this circular mounting groove, and the two are connected by multiple spokes 43 evenly distributed along the circumference. In this embodiment, there are multiple spokes 43, evenly spaced along the circumference, to ensure stable installation of the control unit housing 42 on the air inlet housing 41. An air inlet channel 44 is formed between adjacent spokes 43, and the air inlet channel 44 communicates with the airflow cavity 411. Air carrying pet hair enters the airflow cavity 411 from the air inlet channel 44.

[0031] Reference Figure 9 and Figure 10 The spherical housing 1 has a clearance hole 11 at the position corresponding to the control unit housing 42, so that the outer surface of the control unit housing 42 protrudes from the outside of the spherical housing 1, making it convenient for the user to operate the control components on the control unit housing 42. The surface of the control unit housing 42 is an arc surface that fits the spherical housing 1, so that the control unit housing 42 and the two hemispherical shells 13 together form a complete spherical outline, maintaining the aesthetics and consistency of the entire hair remover.

[0032] Reference Figure 12 The air inlet housing 41, the filter screen 321, and the control unit housing 42 enclose a hair collection chamber 45. The hair collection chamber 45 is connected to the air inlet channel 44 and the filter screen 321, and is used to temporarily store pet hair filtered and trapped by the filter screen 321. When air carrying pet hair enters the airflow chamber 411 from the air inlet channel 44, under the action of the fan, the air passes through the filter screen 321 and enters the fan housing 32, while the pet hair is intercepted by the filter screen 321 in the hair collection chamber 45, thus achieving hair collection and separation.

[0033] Reference Figure 9 and Figure 10The control unit is housed within the housing 42. The control unit includes a switch button 21, a main control circuit board 22, and a status indicator light 23. The switch button 21 is flush with the curved surface of the housing 42 and smoothly transitions to the curved surface, preventing the switch button 21 from protruding and affecting the overall spherical contour of the lint extractor. The status indicator light 23 and the main control circuit board 22 are located inside the housing 42. The main control circuit board 22 is electrically connected to the fan of the suction unit, the status indicator light 23, and the switch button 21, respectively, and is used to control the start / stop of the fan and display the operating status. When the user presses the switch button 21, the main control circuit board 22 receives a signal and controls the fan to start or stop. Simultaneously, the status indicator light 23 lights up or turns off accordingly, indicating the working status of the lint extractor.

[0034] Reference Figure 9 The air outlet assembly includes multiple air outlets 46, which are formed on the surface of the spherical housing 1 and communicate with the interior of the fan housing 32. The central axis of the air outlets 46 is offset from the axis of the parting surface of the spherical housing 1. This offset design helps to adjust the posture of the air vacuum cleaner by using the reaction force generated by the air outlet when the air vacuum cleaner is working, so as to keep it stable.

[0035] Reference Figure 9 The spherical shell 1 also houses a power module, which is fixed within the hemispherical shell 13 where the air outlet assembly is located. The power module's center of gravity is offset from the axis of the parting surface of the spherical shell 1, and its offset direction is opposite to that of the air outlet 46. In this embodiment, the power module's weight is greater than the weight of other components of the lint remover. This offset of the power module's center of gravity lowers the overall center of gravity of the lint remover below the center of the spherical shell 1, creating a self-righting effect and ensuring the lint remover stands stably and is not easily tipped over. The power module includes a rechargeable battery 47 and a wireless charging coil 48. The rechargeable battery 47 is electrically connected to the main control circuit board 22 and the fan, providing them with power. The wireless charging coil 48 is electrically connected to the rechargeable battery 47, enabling wireless charging of the lint remover. Users simply place the lint remover on a dedicated wireless charging base for charging, making the operation simple and quick.

[0036] Reference Figure 5 and Figure 10The spherical shell 1 is covered with an elastic layer 5. In this embodiment, the elastic layer 5 is made of silicone or rubber, which has good cushioning and anti-slip properties. When the hair vacuum is accidentally dropped or bumped, the elastic layer 5 can cushion the impact and protect the internal components from damage. At the same time, the elastic layer 5 can also increase the friction when the user holds it, preventing the hair vacuum from slipping out of their hand. The spherical shell 1 is also provided with an external interface 12, which is used to connect external accessories, such as pet toys, to expand the use scenarios and functions of the hair vacuum in conjunction with entertainment. Combined with the spherical shape of the shell 1, it allows pets such as cats to vacuum up loose hair while playing, reducing the cat's perception of the hair vacuuming process and making it easier for pets to accept.

[0037] The implementation principle of this application embodiment is as follows: When a user needs to use the hair vacuum to clean pet hair, they simply press the switch button 21 on the control unit housing 42. Upon receiving the signal, the main control circuit board 22 starts the fan, and the status indicator light 23 illuminates. After the fan starts, a negative pressure is created in the hair collection chamber 45. Pet hair enters the airflow chamber 411 through the air inlet channel 44 between the spokes 43, and then flows towards the filter screen 321. Under the action of the filter screen 321, the pet hair is trapped in the hair collection chamber 45, while the filtered air passes through the filter screen 321 into the fan housing 32, and finally exits from the air outlet 46 on the surface of the spherical housing 1, completing the hair adsorption and collection process.

[0038] During use, the spherical shape of the entire hair vacuum makes it easy for users to hold without requiring a specific grip posture, reducing hand fatigue. At the same time, the spherical design allows the vacuum to roll on any flat surface, conforming more closely to the pet's skin and reducing discomfort during vacuuming.

[0039] When the lint vacuum's battery is low, the status indicator light 23 will emit a corresponding prompt signal. The user simply needs to place the lint vacuum on the dedicated wireless charging base to charge the rechargeable battery 47 via the wireless charging coil 48. Once charging is complete, the status indicator light 23 will emit a full charge prompt signal, and the user can continue using the lint vacuum.

[0040] Because the center of gravity of the power module is offset from the axis of the parting surface of the spherical shell 1, and its weight is greater than the weight of other components of the lint remover, the overall center of gravity of the lint remover is lower than the center of the spherical shell 1, creating a self-righting effect. Therefore, no matter what angle the lint remover is placed at, it will eventually automatically return to a stable standing position, preventing the internal hair from scattering or the outer shell from being worn due to tipping.

[0041] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
