Detailed implementation mode

[0021] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments; in the following description, providing specific details such as specific configurations and components is only to help comprehensively understand the embodiments of the present invention. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described here without departing from the scope and spirit of the present invention. In addition, for the sake of clarity and conciseness, the description of known functions and structures is omitted.

[0022] It should be noted that, without conflict, the implementation manners and features in the implementation manners of the present invention can be combined with each other.

[0023] In the prior art, pet washing and grooming equipment generally has problems such as insufficient cleaning coverage, inability to dynamically adjust washing and grooming parameters to relieve pet stress reactions, and single - function human - machine interaction. Traditional equipment uses fixed nozzles, resulting in uneven water flow distribution. The brushing mechanism is difficult to adapt to the body characteristics of pets of different body sizes, and the control accuracy of detergent dosage is insufficient. The prior art lacks a real - time monitoring and intervention mechanism for pet emotions. The interaction interface only supports basic function selection and cannot meet the user's requirements for transparent control of the washing and grooming process and parameter customization.

[0024] To solve the above problems, the inventors found that there is a direct correlation between pet washing and grooming effects, the movement trajectory of the equipment, the water flow coverage range, and the emotion response ability. By analyzing the body characteristics of pets, a three - dimensional motion mechanism is proposed to increase the brushing contact area; for the stress reaction problem, a parameter dynamic adjustment mechanism based on biometric recognition is established; to solve the defect of single - function interaction, a two - way data communication interface is developed to realize full - process visualization operation. Therefore, this application proposes a pet washing and grooming machine.

[0025] As Figures 1 - 6As shown in the figure, a pet washing and grooming machine provided by this embodiment includes a machine body 100, a shower mechanism, a brushing mechanism 300, a detergent box 400, a warm air dryer 600, and an electronic control module; A washing and grooming space is provided inside the machine body 100 to form a closed operating environment; the shower mechanism is arranged on the top of the machine body 100. The shower mechanism includes a swing sprinkler 200, and the swing sprinkler 200 realizes left - right swing through hydraulic drive, and is used for evenly spraying water into the washing and grooming space; the brushing mechanism 300 is located inside the washing and grooming space. The brushing mechanism 300 includes a longitudinally movable U - shaped fixing frame 310, and a retractable and movable brush head 320 is arranged inside the U - shaped fixing frame 310; the detergent box 400 is arranged at the rear of the top of the machine body 100, and the detergent box 400 is connected to the inside of the washing and grooming space through an infusion tube, and a direct - current solenoid valve 500 is arranged on the infusion tube; the warm air dryer 600 is arranged at the rear of the machine body 100 and is used for drying pets; the electronic control module includes a pet emotion analysis system and a human - machine interaction system. The pet emotion analysis system is used to identify pet emotions and adjust washing and grooming parameters, and the human - machine interaction system is used to realize information interaction between the user and the washing and grooming machine.

[0026] Specifically, the three - dimensional coverage of the pet's body contour in the washing and grooming space is formed by the longitudinal movement of the U - shaped fixing frame 310 and the retraction of the brush head 320. When a change in the body state of a local area of the pet is detected, the radial displacement of the brush head 320 is driven to keep the contact pressure constant. The hydraulic drive mechanism of the swing sprinkler 200 converts the kinetic energy of water flow into mechanical swing, and the spraying trajectory is fan - shaped and covers the upper area of the washing and grooming space. The water flow impact force is dynamically adjusted according to the swing speed of the nozzle. The emotion analysis system real - time collects data on the change of the pet's pupil and ear posture. When an anxiety feature is recognized, the water flow pressure is automatically reduced and an appeasing audio frequency is started. At the same time, a status prompt is pushed through the human - machine interaction interface for the user to confirm the operation.

[0027] Through the above technical solutions, this application solves the problem of insufficient cleaning coverage rate, realizes the full coverage of the pet's body surface washing and grooming area; establishes a dynamic parameter adjustment mechanism, and automatically optimizes the water temperature and water flow intensity according to the pet's emotion state; provides a visual interaction interface, supports the user to monitor the washing and grooming progress in real - time and adjust the operation parameters, and forms a complete intelligent washing and grooming closed - loop system.

[0028] Further, a water tank 700 is arranged at the rear of the machine body 100. The water tank 700 is connected to the swing sprinkler 200 through an infusion tube, and the infusion tube is connected to an electric pump 710, which is used to control the water in the water tank 700 to enter the swing sprinkler 200.

[0029] Specifically, the water tank 700 and the swing sprinkler 200 form a closed water supply system through an infusion pipe. After the electric pump 710 is started, it extracts water from the water tank 700, pressurizes it, and transports it to the swing sprinkler 200. Through the above technical solution, the present application realizes a stable water supply for the shower mechanism, avoiding the problem of uneven water spraying caused by water pressure fluctuations. The closed-loop control of the electric pump 710 enables the water pressure and flow rate to be adjusted in real time according to the washing and care needs, improving the adaptability to pets of different body sizes. The rear-mounted design of the water tank 700 ensures the water supply efficiency while releasing the washing and care space, avoiding the limitation of the usage scenario caused by the too large volume of the device.

[0030] Furthermore, the swing sprinkler 200 includes a swing nozzle 210 and a spray pipe 220. One end of the swing nozzle 210 is connected to the spray pipe 220. The spray pipe 220 is bent from both ends to the middle, and water outlet holes 221 are evenly distributed on the spray pipe 220. The swing nozzle 210 includes a first rotating housing 211, a fixed housing 212, and a second rotating housing 213. One end of the first rotating housing 211 is connected to the fixed housing 212, the other end of the fixed housing 212 is connected to the second rotating housing 213, and the first rotating housing 211 is connected to the second rotating housing 213 through a synchronizing rod 214; the end of the spray pipe 220 is connected to the end of the first rotating housing 211 away from the fixed housing 212. A water wheel mounting post is provided on one side of the middle hole of the first rotating housing 211, and a water wheel group 215 is provided on the water wheel mounting post. A steering plate 216 is provided on the other side of the middle hole of the first rotating housing 211. A spring mounting post is provided inside the steering plate 216, and a limiting spring 217 is provided on the spring mounting post.

[0031] Specifically, when water flows into the first rotating housing 211 of the swing nozzle 210, the water wheel group 215 generates a rotational motion under the impact of the water flow, driving the first rotating housing 211 to swing around the axis of the fixed housing 212. The synchronizing rod 214 transmits the motion of the first rotating housing 211 to the second rotating housing 213, causing the two to form a linkage swing and avoiding the deflection imbalance caused by unilateral force. The end of the spray pipe 220 swings synchronously with the first rotating housing 211. The bent shape of the spray pipe 220 enables the water flow to spread in different directions during the swing. The water outlet holes 221 at both ends of the spray pipe 220 spray water outward, and the water outlet holes 221 in the middle spray water toward the central area, forming a complementary coverage area. The limiting spring 217 inside the steering plate 216 undergoes a compressive deformation when the nozzle swings to the limit position, absorbing the impact energy through the elastic reset function and at the same time limiting the swing amplitude of the nozzle. The rotational power of the water wheel group 215 and the damping effect of the limiting spring 217 form a dynamic balance, enabling the nozzle to maintain a stable swing frequency within a set angle range.

[0032] Through the above technical scheme, the synergistic effect of the water wheel group 215 and the limit spring 217 of the present application enables the nozzle to swing regularly within the set angle, and the synergistic effect of the curved shape of the nozzle 220 and the swinging motion enables the water flow to form continuous coverage in both the horizontal and vertical directions, thereby maximizing the water flow coverage area in the washing and care space, especially for the bent parts of the pet's trunk and the joints of the limbs, to achieve dead-angle cleaning, significantly improving the consistency of the washing and care effects for pets of different sizes.

[0033] Furthermore, linear guide rails 110 are provided on both sides of the bottom plate of the machine body 100 , and sliders 111 are slidably provided on the linear guide rails 110 , and both ends of the U-shaped fixing frame 310 are fixedly connected to the sliders 111 .

[0034] Specifically, the two ends of the U-shaped fixing frame 310 are respectively fixedly connected to the sliders 111 on both sides, so that the scrubbing mechanism 300 can move along the guide rail with the sliders 111; when it is necessary to adapt to pets of different body lengths, the position of the slider 111 on the guide rail is controlled by the driving device to drive the U-shaped fixing frame 310 to move longitudinally, thereby adjusting the coverage of the brush head 320 in the washing and care space. This structure realizes precise displacement control of the scrubbing mechanism 300 in the longitudinal direction through the cooperation of the guide rail and the slider 111, avoiding cleaning blind spots caused by the fixed structure.

[0035] Furthermore, the U-shaped fixing frame 310 is provided with a multi-stage telescopic device 330, which is used to control the telescopic movement of the brush head 320 to achieve brushing of the pet; the multi-stage telescopic device 330 includes a motor 331 and a coaxial multi-layer screw rod 332 connected to the motor 331, and the multi-layer screw rod 332 is provided with a telescopic sleeve 333 on the outside, and a micro motor 331 is provided inside the end of the outermost telescopic sleeve 333. The micro motor 331 is connected to the brush head 320 for controlling the rotation of the brush head 320.

[0036] Specifically, when the motor 331 is started, the coaxial multi-layer screw 332 drives each layer of the telescopic sleeve 333 to produce axial displacement during the rotation process. The inner screw 332 drives the first layer of telescopic sleeve 333 to move the basic stroke, the middle screw 332 causes the second layer of sleeve to add displacement through gear transmission, and the outer screw 332 drives the third layer of sleeve to further extend through the bevel gear set. The micro motor 331 at the end of the outermost sleeve independently controls the rotation of the brush head 320 to continuously maintain the brushing action during the telescopic process. Through the composite movement of the three-layer screw 332, the brush head 320 can form a combined trajectory of longitudinal superimposed displacement and rotational movement. When encountering a concave part of the pet's body, the outer sleeve can continue to extend to allow the brush head 320 to clean deeply, while the inner sleeve automatically retracts and buffers according to the contact pressure.

[0037] Through the above technical solution, the present application realizes the composite motion control of the brush head 320 in the three-dimensional space, can automatically adjust the contact angle and telescopic depth according to the contour of the pet's body, especially significantly improves the cleaning coverage rate of the pet's armpits and the sunken parts of the abdomen, and solves the problem of cleaning blind spots caused by a single motion trajectory of the existing equipment.

[0038] Furthermore, a hydraulic buffer is provided at the bottom of the brush head 320. The hydraulic buffer absorbs the impact energy through the principle of hydraulic damping to reduce the impact force when the pet hits.

[0039] Specifically, when the pet hits the brush head 320 due to a stress reaction, the impact force is transmitted to the hydraulic buffer through the brush head 320; the piston in the hydraulic buffer is compressed by the external force to force the fluid to pass through the throttle hole to generate a damping effect. In this process, the flow resistance of the fluid increases with the increase of the impact speed, forming a non-linear damping characteristic, realizing the gradient attenuation of the impact force. Since there is no elastic element in the hydraulic system, the energy absorption process will not generate rebound oscillation, and at the same time, the rigid support required when the brush head 320 works normally is maintained.

[0040] Through the above technical solution, the present application can effectively reduce the peak value of the instantaneous impact force generated when the pet hits the brush head 320, avoid the risk of epidermal damage or bone contusion caused by a rigid collision, and at the same time ensure that the brushing mechanism 300 maintains a stable working posture in a non-impact state. This solution is particularly applicable to the sudden impact load conditions caused by unpredictable stress behaviors during the pet washing and care process.

[0041] Furthermore, one end of the body 100 has an inlet and outlet, and a door panel 120 is hinged on one side of the inlet and outlet; exhaust vents 130 are provided on both sides of the body 100, and exhaust fans 140 are provided in the exhaust vents 130.

[0042] Specifically, the door panel 120 is connected to the side wall of the body 100 through a hinge. When the door panel 120 is closed, a sealed space is formed with the sealing strip. The exhaust vents 130 are symmetrically distributed on both sides of the body 100. After the exhaust fans 140 are started, a transverse air flow path is formed to direct the moisture and heat generated during the washing and care process out. The transparent material of the door panel 120 enables the pet to maintain visual contact with the external environment during the washing and care process, reducing the psychological oppression caused by the enclosed space. The exhaust fans 140 are linked with the warm air system during the drying stage to accelerate the efficiency of the hot air circulation, and at the same time avoid the accumulation of high-temperature steam in the cabin through continuous ventilation.

[0043] Through the above technical solution, the present application effectively reduces the anxiety of the pet caused by the enclosed space during the washing and care process, maintains the comfort of the cabin environment through continuous air exchange, reduces the discomfort of the pet's breathing caused by poor ventilation, and at the same time improves the thermal energy utilization efficiency during the drying stage.

[0044] Furthermore, the pet emotion analysis system includes: an image acquisition unit, which can specifically adopt a camera 900 for acquiring the micro-expression features of the pet's face; an emotion recognition unit that analyzes the multi-dimensional features of the pet's emotion state based on the Qianwen large model API; and a parameter adjustment unit that adjusts system parameters such as water temperature, wind strength, and sound frequency parameters based on emotion feature parameters.

[0045] Through the above technical solution, this application can monitor the emotional fluctuations of pets during the washing and grooming process in real time, automatically adjust the water temperature to avoid the risk of scalding, reduce the warm air speed to reduce noise stimulation, and relieve anxiety through sound frequency intervention. This solution effectively reduces the struggling behavior of pets due to stress reactions and improves the safety and comfort of the washing and grooming process.

[0046] Furthermore, the human-computer interaction system includes: a display unit, which can specifically adopt a display screen 800 for real-time display of the progress of the washing and grooming process, machine status, and environmental parameters; an input unit for users to input washing and grooming parameters and function selections; and a control unit for controlling the operation of the washing and grooming machine according to user inputs.

[0047] Specifically, the display unit continuously outputs a process progress bar, the current water temperature value, and the device operation status indicator during the washing and grooming process, enabling users to grasp the conversion nodes of the washing and grooming stages in real time. The input unit provides a parameter adjustment interface where users can select the short-haired cat mode or long-haired dog mode according to the pet breed and manually adjust the water spray pressure gear and drying duration. After receiving the set parameters transmitted by the input unit, the control unit generates corresponding pulse signals to drive the electric pump 710 to adjust the water pressure and simultaneously sends a temperature control instruction to the warm air dryer 600. The three units establish a communication link through a data bus to form a closed-loop system for parameter setting, status feedback, and device control.

[0048] Through the above technical solution, this application realizes the real-time transparent display of the data during the washing and grooming process, enabling users to intuitively monitor the operation status of the device; provides a multi-level parameter customization function to meet the different washing and grooming needs of pets with different body sizes and hair types; and establishes an accurate correspondence between user instructions and device actions to ensure that the washing and grooming process is executed according to the preset parameters.
