[0019] Reference Figure 1 As shown, this is a pet cleaning device 1000 provided in an embodiment of the present invention. This device aims to solve technical problems such as difficulty in cleaning the abdomen and paws, high stress response in pets, and incomplete drying during traditional pet cleaning processes. Its main structure includes a housing 100, which serves as the overall supporting frame. Inside, a cleaning chamber 101 with an upward-facing opening is formed. The depth of the cleaning chamber 101 is ergonomically designed to ensure sufficient volume to accommodate pets of different sizes, while its sidewall height forms an effective water-blocking structure to prevent water from splashing outside the housing 100 during cleaning. The opening size at the top of the cleaning chamber 101 is optimized, allowing users to easily insert their hands into the cleaning chamber 101 to assist in cleaning while standing or sitting.

[0020] To allow users to monitor the cleaning progress and observe their pet's condition in real time, a transparent window is embedded in the front wall of the enclosure 100. This window can be made of tempered glass or high-strength transparent acrylic material and has an anti-fogging coating, ensuring a clear view even when the cleaning chamber 101 is filled with warm steam, allowing for easy observation of any anxiety or discomfort in the pet. A water spray nozzle 102 is installed on the inner wall of the cleaning chamber 101. This nozzle is connected to the water supply system via a hose of sufficient length for the user to hold and flexibly clean the pet's back, head, and other upper surfaces. Figure 11 As shown, an instant water heater 127 is provided on the water inlet side of the shower head 102, so that the shower head 102 can produce hot water.

[0021] However, existing handheld showerheads struggle to reach the pet's abdomen and the intricate spaces between its paws when it's standing. When a pet is upright, its abdomen is close to the ground and its limbs are together; forcibly turning the pet over for washing can easily cause panic and struggle. Therefore, referring to... Figure 1 and Figure 2 As shown, this embodiment innovatively arranges a flexible chassis dynamic cleaning system in the cleaning chamber 101. The system mainly consists of a flexible filter 103 and a cleaning drum 105.

[0022] Specifically, the flexible filter 103 is horizontally mounted above the bottom of the washing chamber 101, serving as the direct support surface for the pet. Unlike traditional rigid grilles, the flexible filter 103 is made of high-elasticity silicone or TPE (thermoplastic elastomer). This material not only has excellent hydrophobicity and chemical resistance, but more importantly, it has skin-friendly and non-slip properties. Its feel is similar to a soft yoga mat or artificial turf, significantly reducing discomfort and resistance when the pet's feet come into contact with hard objects, and increasing the pet's standing stability.

[0023] The cleaning roller 105 is located below the flexible filter 103, forming the core of the bottom power cleaning system. Multiple cleaning rollers 105 can be used, and their outer perimeter walls are equipped with multiple alternating or staggered spray nozzles 106 and brushes 107. To achieve the function of "brushing and spraying simultaneously," the cleaning roller 105 has a hollow water passage inside, which is in fluid communication with the multiple spray nozzles 106 on the outer wall. Mechanically, a connecting nozzle structure extends from the axial position of the water passage at the end face of the cleaning roller 105. This connecting nozzle connects to an external water supply pipeline and water pump via a rotary joint, ensuring that the water path remains sealed and unobstructed even when the roller rotates at high speed. The intelligent controller controls the start and stop of the water pump, precisely controlling whether the spray nozzles 106 spray water and the spray pressure.

[0024] It should also be noted that the end of the cleaning roller 105 is rotatably connected to the inner wall support of the housing 100 via a sealed bearing. A double-layer skeleton oil seal or mechanical seal ring is provided around the bearing to achieve dynamic and static sealing, preventing sewage from the cleaning chamber 101 from seeping into the bearing and causing corrosion. In terms of power, a driven gear is also provided at the end of the cleaning roller 105. This gear is located in the partition space of the side wall of the cleaning chamber 101 (not inside the cleaning chamber 101), and is driven by a motor-driven drive gear to rotate or reciprocate.

[0025] To balance cleaning power and comfort, the brushes 107 on the roller are made of a flexible material (such as soft nylon or silicone tentacles). The spray nozzles 106 are designed to face downwards from the flexible filter 103, and the length of the brushes 107 is designed to just touch and slightly lift the flexible filter 103. The flexible filter 103 has multiple holes (drainage holes) corresponding to the path of the brushes 107. When the roller rotates, the brushes 107 extend through these holes and out of the mesh surface, directly and physically scrubbing the crevices of the pet's paw pads; simultaneously, pressurized hot water sprayed from the spray nozzles 106 passes through the holes, precisely impacting the pet's feet and washing away the scrubbed dirt. Even more advantageously, when the pet is lying down, the elasticity of the flexible filter 103 causes the pet's weight to slightly sink the mesh surface, allowing the brushes 107 to reach deeper and perform fully automatic cleaning of the pet's abdomen, completely solving the problem of cleaning blind spots on the abdomen.

[0026] Reference Figure 3 As shown, to further enhance the therapeutic function of the device, in some embodiments, the outer peripheral wall of the cleaning roller 105 is not a perfect cylindrical surface, but is provided with raised massage portions 104, making the cross-section of the cleaning roller 105 resemble a cam structure. The height of the raised massage portions 104 is slightly higher than the other surfaces of the roller, allowing them to periodically contact the flexible filter 103 and generate a lifting action. The brushes 107 located on the raised massage portions 104 are shorter than the brushes 107 at other locations on the cleaning roller 105 to match the height difference of the protrusions. Alternatively, the raised massage portions 104 can be covered with a high-density sponge or soft rubber layer to increase their flexibility. When the roller rotates, the raised massage portions 104 periodically lift the pet's paws or abdomen through the flexible filter 103, simulating the kneading action of a human hand to achieve dynamic massage.

[0027] Reference Figure 2As shown, in some embodiments, the inner wall of the cleaning chamber 101 is provided with a protrusion 114, and the edge of the flexible filter 103 is provided with a matching rigid frame or hanging bracket 115. The hanging bracket 115 overlaps the protrusion 114, thereby stably supporting the flexible filter 103. The top of the hanging bracket 115 is provided with a handle 116, which allows the user to easily remove the entire flexible filter 103 by holding the handle 116. This design greatly facilitates the user in regularly removing shed hair accumulated on the surface and in the pores of the flexible filter 103, preventing bacterial growth.

[0028] For information on drainage and filtration systems, please refer to... Figure 5 and Figure 6 As shown, in some embodiments, the bottom of the washing chamber 101 (below the roller) is provided with a collection trough 117. The lowest point of the trough 117 is provided with a nozzle for connecting to an external drain pipe, and an odor-proof drain 118 is installed inside the nozzle. A filter screen 119 is horizontally mounted inside the trough 117. This filter screen 119 has a small aperture, which can effectively intercept and collect a large amount of pet hair, mud, and other debris during the washing process, preventing blockage of the drain 118 and the sewer. (Refer to...) Figure 7 As shown, the filter screen 119 has a grooved structure, and a supporting protrusion is provided around its outer perimeter, allowing it to be directly suspended. It should be noted that the installation position of the cleaning roller 105 avoids being directly above the groove 117, leaving operating space so that the user can easily remove and clean the filter screen 119. The housing 100 has a drain outlet communicating with the cleaning chamber 101, and an electrically controlled drain valve is installed on the outlet side pipe to control whether the cleaning chamber 101 is in a water-filling or draining state.

[0029] Regarding water intake and water treatment, the cleaning chamber 101 is equipped with a water outlet and a high-sensitivity water level sensor. The water outlet is connected to a water supply device with constant temperature regulation to fill the cleaning chamber 101 with water. To achieve deep cleaning, a microbubble generator is integrated into the device. Depending on its principle, the microbubble generator can be arranged at the bottom of the cleaning chamber 101 or connected in series in the water inlet pipe of the water outlet. The microbubble generator can generate and release bubbles using the Venturi effect (using changes in fluid velocity to generate negative pressure for air intake), porous media diffusion dissolved gas release (similar to air stones in high-pressure aquariums), or mechanical stirring and shearing principles. The microbubble generator can be a commercially available, mature product, which is existing technology. Its internal structure will not be described in detail here, but its application location and functional combination are the focus of this embodiment.

[0030] Reference Figure 1As shown, in some embodiments, to prevent pets from escaping and water from splashing, the pet cleaning device 1000 also includes a telescopic roller shutter 120. The telescopic roller shutter 120 is located at the upper opening of the cleaning chamber 101, similar to a roller shutter door structure. The telescopic roller shutter 120 is used to cover or open the upper opening of the cleaning chamber 101, and the handle end of the telescopic roller shutter 120 can be fixed to the front side of the housing 100 by means of a buckle or magnetic attraction, thereby keeping the upper opening of the cleaning chamber 101 covered.

[0031] The drying system is another major highlight of this device. (Refer to...) Figure 2 As shown, in some embodiments, the pet cleaning device 1000 further includes a drying assembly, which includes a heating element 108, an air duct 109, and a high-pressure centrifugal fan 110. The heating element 108 is located within the air duct 109 and preferably uses a PTC ceramic electric heating element, which features rapid heating, no open flame, and constant temperature safety. The air duct 109 is integrated into the rear side wall interlayer of the housing 100 and has an air inlet 111 and an upper air outlet 112 and a lower air outlet 113 communicating with the washing chamber 101. The air inlet 111 communicates with the external environment, the upper air outlet 112 is inclined downwards and located above the flexible filter 103, mainly used to dry the pet's back and head; the lower air outlet 113 is located below or to the side of the washing roller 105, with the air outlet direction upwards.

[0032] After cleaning the pet, the retractable roller shutter 120 is pulled up to form a relatively enclosed drying chamber, and the drying mode can be activated to open the drying components. At this time, the heating element 108 generates heat, and the centrifugal fan 110 rotates to draw in outside air and send it into the cleaning chamber 101 through the heating element. Due to the suction characteristics of the centrifugal fan 110, hot air can flow out from both the upper air outlet 112 and the lower air outlet 113 simultaneously (see reference). Figure 2 (As indicated by the dashed arrow). This design creates a three-dimensional airflow with vertical convection, resulting in extremely even drying of the pet, especially in hard-to-dry areas like the abdomen and inner sides of the limbs. Simultaneously, the hot air from the lower air outlet 113 passes through the flexible filter 103, drying both the washing drum 105 and the flexible filter 103 itself, keeping them clean and dry and preventing mold growth—a double benefit.

[0033] Considering the convenience of large or elderly pets entering the washing room 101, it is understandable that, due to the height of the washing room 101, users may find it difficult to lift and place a large pet into the washing room 101. Based on this, referring to... Figure 1 As shown, this embodiment has a laterally movable sliding door 129 (or sliding door) on the front side of the housing 100 to open or close the cleaning chamber 101. The sliding door 129 can be closed and locked using a snap-on or magnetic method. Referring to the diagram, the sliding door 129 is used in conjunction with the other door. Figure 8As shown, the pet cleaning device 1000 also includes a foldable ramp assembly 200. The foldable ramp assembly 200 is positioned corresponding to the opening and closing door 129 and is concealed at the bottom of the housing 100. The foldable ramp assembly 200 includes a guide rail 201, a first ramp plate 204, and a second ramp plate 205. The surfaces of the first ramp plate 204 and the second ramp plate 205 are coated with a PE anti-slip plate or a frosted anti-slip layer. (Refer to...) Figures 9 to 11 As shown, the guide rail 201 is fixedly installed on the bottom chassis of the housing 100. The first ramp plate 204 is slidably connected to the guide rail 201 through a set of pulleys 207. The first ramp plate 204 and the second ramp plate 205 are rotatably connected by a damping hinge. The guide rail 201 is provided with a sliding groove 202 extending along the front-rear direction of the housing 100. The side wall at the front end of the sliding groove 202 is provided with an upwardly extending limiting groove 203 (approximately a circular groove, but also an L-shaped or J-shaped groove). The side of the first ramp plate 204 is provided with a limiting post 206.

[0034] This component has an unfolded state and a folded state: such as Figures 8 to 10 As shown, when needed, the first ramp 204 and the second ramp 205 can be pulled outwards, so that the foldable ramp assembly 200 is in the unfolded state. At this time, the first ramp 204 extends out of the guide rail 201, and the limiting post 206 slides in and engages with the limiting groove 203, thereby forming a stable triangular support structure with the ground and maintaining an inclined state. At this time, pets can easily enter the washing chamber 101 through the ramp. When not in use, refer to... Figure 1 As shown, the foldable ramp assembly 200 is in a stowed state. The first ramp plate 204 is horizontally pushed into the guide rail 201 and stowed. The second ramp plate 205 is folded and placed vertically behind the panel of the housing 100, without occupying external space.

[0035] In some embodiments, refer to Figure 1As shown, the cleaning chamber 101 has a pet leash hook 121 for hanging a pet leash to prevent pets from jumping out. A human body sensor 123 is also installed inside the cleaning chamber 101, which can be understood in the professional field as a biological liveness detection sensor. To overcome the interference of high humidity, water mist, and hot steam inside the cleaning chamber 101, this sensor is preferably a millimeter-wave radar sensor; however, a modified pyroelectric infrared sensor can also be used in a low-cost solution. The millimeter-wave radar sensor has the ability to penetrate water mist, and can not only sense whether a pet has entered the cleaning chamber 101, but also monitor the pet's subtle breathing movements. A waterproof light 122 is also installed at the top of the cleaning chamber 101. When the biological liveness detection sensor detects a pet or a user's arm inside the cleaning chamber 101, the controller can automatically turn on the waterproof light 122 to supplement the light, making it convenient to use. In addition, a temperature sensor is also installed inside the cleaning chamber 101 to detect the water temperature, preventing the pet from being scalded by excessively hot water. The bottom of the cabinet 100 also utilizes the remaining space to provide a drawer 124 for storing items such as shower gel and towels. The bottom of the cabinet 100 is equipped with adjustable feet 125 to accommodate uneven surfaces.

[0036] This invention also provides a cleaning method for controlling the pet cleaning device 1000 described in the above embodiments. This cleaning method can also be understood as a control method for the pet cleaning device 1000, see reference... Figure 1 As shown, commands are input via a control panel (including a display screen 126 and control buttons 128) integrated on the top of the housing 100. This method mainly includes the following steps and modes: 1. Responding to the activation of foot cleaning mode: The controller opens the drain valve, starts the washing drum, and simultaneously activates the water pump, which in turn controls the spray nozzles to spray warm water onto the flexible filter. At this time, the brushes on the drum pass through the holes in the flexible filter to gently wash the pet's paws. This mode is suitable for situations where pets have just returned from a short outing and only need a quick wash of their paws, saving considerable time.

[0037] 2. Responds to entering soaking cleaning mode (deep SPA mode): The controller closes the drain valve and opens the water outlet to fill the cleaning chamber with water. The system monitors the water level sensor in real time, and closes the water outlet once it receives a signal that the water level has reached a preset threshold height (e.g., submerging the pet's abdomen; this threshold height can be set manually or selected from a pre-set value based on the pet's species). Subsequently, the system activates the microbubble generator. At this time, the controller can also control the cleaning drum to rotate at a low speed (i.e., the cleaning drum rotates slower in soaking cleaning mode than in foot cleaning mode, primarily to agitate the water flow).

[0038] 3. Responding to the activation of foot massage mode: The controller controls the cleaning drum to rotate to a specific angle, so that the raised massage part faces the flexible filter screen, and controls the cleaning drum to reciprocate (oscillate) at a small angle, so that the raised massage part reciprocates to lift and rub against the flexible filter screen.

[0039] It's important to explain that activating the foot massage mode after the basic foot cleaning mode offers significant physiological benefits. This mode provides a non-invasive massage to the pet's feet and abdomen, promoting subcutaneous microcirculation, stimulating the expansion and contraction of subcutaneous capillaries, accelerating blood circulation, and helping to metabolize fatigue-causing substances such as lactic acid. It also has a therapeutic effect on older pets or those with joint problems. Furthermore, when the raised massage section lifts the flexible filter, the filter rubs against the pet's feet, removing stubborn stains. For breeds with many skin folds, such as Bulldogs and Shar Peis, the lifting motion of the massage protrusions physically opens up the skin folds on the abdomen and armpits, exposing hidden skin surfaces, eliminating cleaning dead spots, and preventing skin diseases caused by dirt buildup in the folds.

[0040] 4. Responds to entering the foot wash-massage cycle mode: The controller controls the cleaning drum to rotate back and forth for a full revolution, so that the raised massage head, spray nozzles and brushes can face the flexible filter in sequence, thus achieving a gradual cleaning-massage cycle.

[0041] Furthermore, it should be noted that because pets have dense fur, and the diameter of their hair follicles is typically around 80-150 micrometers, ordinary water flow, due to its high surface tension, has difficulty penetrating deep into the hair follicles, only able to wash away surface dirt. The pet cleaning device in this embodiment, after entering the soaking cleaning mode, allows for a soaking bath for the pet. A water level sensor controls the water level, which can also be set via the control panel. A microbubble generator releases billions of microbubbles with a diameter of less than 50 micrometers into the water. When these bubbles rupture inside the pet's hair follicles, they generate instantaneous micro-explosion energy, which can "blast" out accumulated oil, dander, and bacteria deep within the hair follicles, achieving deep cleaning without vigorous scrubbing. In addition, the microbubble surface carries a negative charge, while most dirt, bacteria, and oil particles carry a positive charge. The microbubbles act like magnets, actively attracting these dirt particles, carrying them away from the skin and causing them to float to the surface. This is extremely effective in removing the pet's unique body odor (especially sebum secretions). Furthermore, compared to high-pressure water jets, microbubble cleaning works through immersion and gentle water flow, greatly reducing noise and mechanical impact, creating a quiet environment similar to a "milk bath," which has a calming effect and is very suitable for timid pets and those prone to stress.

[0042] 5. Responds to entering fully automatic circulating cleaning mode: In some other embodiments, the cleaning method of this embodiment also includes a fully automatic process: in response to the user's "one-click start" command, the pet cleaning device is controlled to first enter the soaking cleaning mode (pre-wash and degreasing); then the pet cleaning device is controlled to enter the paw cleaning mode for a first time value (e.g., 3 minutes, focusing on brushing); then the pet cleaning device is controlled to enter the paw massage mode for a second time value (e.g., 5 minutes, relaxing and soothing); finally, the drain valve is controlled to open to drain the washing chamber, and the drying mode is automatically connected.

[0043] It should be explained that after entering the fully automatic circulating cleaning mode, the pet cleaning device automatically cycles through the steps of soaking, washing feet, massaging, draining, and drying. This eliminates the need for users to frequently switch between other modes manually, allowing for multiple cleaning functions to be achieved with a single button. Users can focus on observing through the window or using the top opening to assist in cleaning their pet's head or back, which is very convenient and saves time.
