Description

Technical Field

[0001] This utility model relates to the field of pet cleaning equipment technology, specifically to a pet washing machine. Background Technology

[0002] Currently, pet ownership is becoming increasingly common in households. Because pets' sebaceous gland secretions have an odor, and dust particles can cause their fur to become matted and smelly, owners need to regularly clean their pets to maintain skin hygiene. Most owners choose manual cleaning, applying detergent by hand and rinsing with a showerhead. However, the force of the water can easily cause stress in pets, causing them to run away. The entire cleaning process is time-consuming, laborious, and provides a poor experience.

[0003] A Chinese utility model patent with patent number ZL202320831957.5 (publication number CN219719388U), entitled "Spraying Mechanism and Pet House," discloses a pet house for pet washing. The pet house is equipped with a spraying assembly, which includes a spraying drive fixed to the outside of the house body and a spraying arm extending into the interior cavity. The spraying drive can drive the spraying arm to rotate along its own axis, and the spray holes on the spraying arm can spray out clean water and detergent. However, this spraying mechanism has the following problems during use: First, the spray holes on the spraying arm are distributed along the length direction, and the water flow in the spray holes is jetted in a cylindrical shape, resulting in concentrated impact but a small coverage area, making it easy for the pet to not be thoroughly cleaned; Second, the spray holes on the spraying arm are shared by both clean water and detergent. When detergent residue remains inside the spraying arm, it will cause the sprayed clean water to be contaminated, thus affecting the cleaning effect on the pet.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pet washing machine that can avoid cleaning dead corners and has a good cleaning effect, in view of the above-mentioned existing technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the pet cleaning machine includes:

[0007] The chassis has internal storage space.

[0008] A spray assembly is disposed within the accommodating space;

[0009] A washing assembly is disposed inside the top of the chassis, and the washing assembly is connected to the spray assembly;

[0010] Its characteristic is that the spray assembly is provided with:

[0011] The first nozzle is provided in multiple and spaced apart at the bottom of the spray assembly, and the first nozzle includes at least an expansion section for spraying clean water downwards.

[0012] The second nozzle is connected to the washing assembly at its top. The first nozzle and the second nozzle are arranged at intervals and cross each other. Each second nozzle includes a straight section and a bent section arranged from top to bottom.

[0013] To increase the water coverage area, preferably, the first nozzle includes a vertical section and an expansion section, with the bottom end of the vertical section connecting to the top end of the expansion section. The expansion section of the first nozzle has a conical cross-section, allowing water to be sprayed downwards from the expansion section to form a fan-shaped spray area. This results in a large coverage area and high spray intensity. Adjacent first nozzles can form intersecting spray areas, and the water sprayed from all the first nozzles can converge into a single line. Furthermore, the rotation of the spray assembly enables complete coverage of the accommodating space.

[0014] To achieve uniform spraying, preferably, the second nozzles are arranged in pairs, with the bent sections of each pair inclined downwards towards each other, and the angle α between the bent sections and the vertical direction ranging from 20° to 45°. When the angle α between the bent sections and the vertical direction is less than 20°, the detergent jet is too vertical, and the detergent cannot be effectively sprayed onto the pet; when the angle α between the bent sections and the vertical direction is greater than 45°, the detergent from adjacent second nozzles has already converged and spilled before being sprayed onto the pet, resulting in detergent waste and the pet's lower body not being properly cleaned.

[0015] To avoid cleaning dead spots, preferably, the spray assembly is provided in two sets, respectively located at the top of the left and right walls of the accommodating space. Each set of spray assemblies includes a housing located at the top of the corresponding side wall, a spray arm rotatably connected to the housing, and a cover covering the top of the housing. The bottom of the housing has mounting ports for the first and second nozzles on the bottom of the spray arm to be exposed. The spray assemblies on the left and right walls operate simultaneously, forming overlapping coverage areas to avoid cleaning dead spots and ensuring that every area in the space is sprayed with water from at least one direction. Furthermore, the two sets of spray assemblies improve the cleaning efficiency for pets, thereby reducing cleaning time.

[0016] For ease of rotation, preferably, the spray arm is equipped with a rotating shaft, and a driving component for rotating the rotating shaft is provided on the side wall of the housing. A bushing is provided on the rotating shaft. The spray arm is rotatably connected to the inside of the housing via the rotating shaft. The driving component can drive the rotating shaft to rotate, thereby causing the spray arm to rotate synchronously. The first and second spray heads located on the spray arm can cover a larger area during rotation, thus improving cleaning efficiency and avoiding cleaning dead zones. Simultaneously, the bushing supports and positions the rotating shaft.

[0017] To improve spraying efficiency, preferably, each of the spray arms can reciprocate along a direction close to or away from the central axis of the housing, with the rotation angle β of each spray arm ranging from 0° to 60°. When the spray arm cannot rotate, cleaning dead zones will appear within the accommodating space, resulting in the pet not being properly cleaned. When the rotation angle β of the spray arm is greater than 60°, the nozzles on the spray arm will ineffectively spray the edges of the accommodating space, wasting water and detergent, and also reducing the oscillation frequency of the spray arm, leading to a decrease in cleaning efficiency.

[0018] To improve sealing, preferably, the spray arm includes a body and an upper cover that fits onto the body. A sealing element is provided between the upper cover and the body, and fasteners are also provided on the upper cover and the body. The spray arm can store and spray clean water, the fasteners secure the upper cover to the body, and the sealing element fills the gap between them, thus preventing water leakage.

[0019] To facilitate the spraying of clean water, preferably, the top cover and the main body form a cavity for storing clean water, and a water inlet pipe is provided on the side wall of the main body for the clean water to enter the cavity. The end of the water inlet pipe is connected to an external water source, and clean water enters the cavity through the water inlet pipe. In the cleaning mode, clean water can be sprayed out from the first nozzle at the bottom of the cavity to clean the pet.

[0020] To facilitate detergent supply, the washing assembly preferably includes a detergent storage container, a pump, and a distributor. A first pipe connects the container and the pump, and a second pipe connects the pump and the distributor. The distributor has multiple third pipes that deliver detergent to various second nozzles. Before washing the pet, detergent is sprayed onto its body. The detergent in the container, propelled by the pump, flows along the first and second pipes into the distributor. The distributor distributes the detergent into the various third pipes, and the detergent in the third pipes is finally sprayed onto the pet in foam form from the tips of the second nozzles.

[0021] To facilitate wastewater discharge, preferably, the bottom and side walls of the accommodating space are provided with multiple drainage holes near the lower end, which are connected to a wastewater tank at the bottom of the casing. The clean water sprayed from the first nozzle located above the accommodating space rinses away detergent foam from the pet. Wastewater generated during the cleaning process flows downwards through the drainage holes into the wastewater tank at the bottom of the casing, and is finally discharged to the outside of the casing through a drain pipe.

[0022] Compared with the prior art, the advantages of this utility model are as follows: the spray arm is provided with a first nozzle for spraying clean water and a second nozzle for spraying detergent, which are arranged in a cross pattern and at intervals. The two nozzles work independently and will not contaminate each other. At the same time, the end of the first nozzle is provided with an expansion section. After the clean water is sprayed out from the expansion section, it can form a fan-shaped spray area with a large coverage area and high spray intensity. Adjacent first nozzles can form cross spray areas, avoiding cleaning dead corners and achieving good cleaning effect. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 8 As shown, the pet cleaning machine of this utility model includes a housing 1, a spray assembly 2, a washing assembly 3, a rotating shaft 4, a drive component 5, a bushing 6, and a seal 7.

[0034] like Figure 1 As shown, the interior of the chassis 1 forms a storage space 11. A door (not shown in the figure) is provided on the front side of the storage space 11. Spraying components 2 are symmetrically arranged at the top of the left side wall 111 and the right side wall 112 of the storage space 11. The two sets of spraying components 2 work simultaneously to form a cross-coverage area, avoiding cleaning dead corners and ensuring that every part of the storage space 11 can be sprayed by water from the spraying components 2 in at least one direction. At the same time, the two sets of spraying components 2 can improve the cleaning efficiency of the pet, thereby reducing the cleaning time. Multiple drain holes 113 are provided on the bottom wall and the side walls near the lower end of the storage space 11. Wastewater generated during the pet cleaning process can enter the wastewater tank (not shown in the figure) at the bottom of the chassis 1 through the drain holes 113 and finally be discharged to the outside of the chassis 1 through the drain pipe (not shown in the figure).

[0035] like Figure 2 and Figure 3As shown, each spray assembly 2 includes a housing 23 disposed on the corresponding side wall of the accommodating space 11, a cover 24 covering the housing 23, and a spray arm 25 rotatably connected inside the housing 23. In this embodiment, the spray arm 25 is provided with five first nozzles 21 and four second nozzles 22. The bottom of the housing 23 is provided with mounting ports 231 for the first nozzles 21 and second nozzles 22 to be exposed. At the same time, the housing 23 and the cover 24 can protect the spray arm 25 from damage. The spray arm 25 is provided with a rotating shaft 4 extending along the length direction. The spray arm 25 is rotatably connected to the housing 23 through the rotating shaft 4. The rotating shaft 4 is provided with a bushing 6 for support and positioning. The side wall of the housing 23 is provided with a driving component 5 for driving the rotating shaft 4 to rotate. The driving component 5 can be a DC motor, a servo motor, etc. In this embodiment, the preferred driving component 5 is a high-precision stepper motor. When the stepper motor receives a pulse signal, it can rotate a fixed angle, thereby precisely controlling the rotation angle. Each spray assembly 2 can rotate along the direction close to or away from the central axis A of the chassis 1. The rotation angle β of each spray arm 25 is in the range of 0° to 60°. When the spray arm 25 cannot rotate, cleaning dead corners are likely to appear in the accommodating space 11, resulting in the pet not being cleaned properly. When the rotation angle β of the spray arm 25 is greater than 60°, the nozzles on the spray arm 25 will spray ineffectively on the edge of the accommodating space 11, which wastes clean water and detergent, and also reduces the swing frequency of the spray arm 25, resulting in a decrease in cleaning efficiency. Therefore, the preferred rotation angle β in this embodiment is 45°.

[0036] The spray arm 25 includes a body 251 and an upper cover 252 that fits onto the body 251. The upper cover 252 and the body 251 enclose a cavity 2511 for storing clean water. A water inlet pipe (not shown) is provided on the side wall of the body 251 for allowing clean water to enter the cavity 2511. The end of the water inlet pipe is connected to an external water source, and clean water enters the cavity 2511 through the water inlet pipe. In cleaning mode, clean water can be sprayed from the first nozzle 21 at the bottom of the cavity 2511 to clean the pet. A sealing element 7 is provided between the upper cover 252 and the body 251. Fasteners (not shown) are also provided on the upper cover 252 and the body 251. The fasteners secure the upper cover 252 to the body 251, while the sealing element 7 fills the gap between the upper cover 252 and the body 251, thus preventing clean water in the cavity 2511 from leaking out of the gap. Figure 5 As shown, the first nozzle 21 in this embodiment includes a vertical section 211 and an expansion section 212 that are joined together. The cross-section of the expansion section 212 is conical, and clean water can form a fan-shaped spray area after being sprayed downward from the expansion section 212 (e.g., Figure 4As shown), it has a large coverage area and high spray intensity. Adjacent first nozzles 21 can form intersecting spray areas. The clean water sprayed from all the first nozzles 21 can converge into a line. At the same time, with the rotation of the spray arm 25, it can achieve full coverage of the accommodating space 11.

[0037] To facilitate the supply of detergents, such as Figure 1 and Figure 6 As shown, in this embodiment, a washing assembly 3 is provided inside the top of the casing 1. The washing assembly 3 includes a box 31 for storing detergent, a pump 32, and a distributor 33. In this embodiment, the pump 32 is preferably an air pump, which can mix the sucked-in air with the detergent to generate foam. A first pipe 34 is provided between the box 31 and the pump 32, and a second pipe 35 is provided between the pump 32 and the distributor 33. The distributor 33 is provided with multiple third pipes 36 that respectively deliver detergent foam to each second nozzle 22. Before washing the pet, detergent needs to be sprayed on its body. The detergent in the box 31 can enter the distributor 33 along the first pipe 34 and the second pipe 35 under the delivery of the pump 32. The distributor 33 distributes the detergent foam to each third pipe 36. The detergent foam in the third pipe 36 is finally sprayed onto the pet from the end of the second nozzle 22. The second nozzle 22 is inserted through the spray arm 25, and in this embodiment, there are two pairs of second nozzles 22. The bent section 222 of each pair of second nozzles 22 is inclined from top to bottom in the direction of mutual approach. When the angle α between the bent section 222 and the vertical direction is less than 20°, the detergent jet is too vertical and the detergent cannot be effectively sprayed on the pet. When the angle α between the bent section 222 and the vertical direction is greater than 45°, the detergent from the adjacent second nozzles 22 has already converged and spilled before being sprayed on the pet, which not only wastes detergent, but also fails to clean the lower half of the pet. Therefore, in this embodiment, the preferred angle α between the bent section 222 and the vertical direction is 30°. At this time, each pair of second nozzles 22 can spray an arc-shaped jet and create a convergence point on the pet, thereby ensuring that the detergent is sprayed evenly on the pet.

[0038] The working principle of the pet washing machine in this embodiment is as follows: The pet is placed in the housing space 11 of the machine box 1 and the door is closed. The bubble pump switch and stepper motor on the washing assembly 3 are turned on. The detergent in the box 31 flows sequentially along the first pipe 34, the second pipe 35, the distributor 33 and the third pipe 36 under the delivery of the bubble pump, and finally enters each of the second nozzles 22. The spray outlets on each of the second nozzles 22 can spray detergent foam onto the pet. Then the bubble pump is turned off to stop the supply of detergent. At this time, the external water source is turned on, and clean water enters the cavity 2511 of the spray arm 25 through the water inlet pipe, and is finally sprayed by the first nozzle 21. The two sets of spray arms 25 rotate back and forth under the drive of the stepper motor to rinse the foam off the pet. The wastewater generated by rinsing enters the wastewater tank at the bottom of the machine box 1 through the drain hole 113, and is finally discharged to the outside of the machine box 1 through the drain pipe.
