Description

Technical Field

[0001] This invention relates to an animal foot-washing device. Background Technology

[0002] For example, commercially available pet foot washing cups and other pet foot washing devices have been widely used. Currently, most pet foot washing devices are pet foot washing cups that can only wash one foot at a time, while a few are foot washing basins or multi-cup pet foot washing devices that can wash multiple feet at the same time. Multi-cup pet foot washing devices are generally foot washing devices that integrate two or four pet foot washing cups into one pet foot washing device. However, regardless of the type of pet foot washing device, they generally lack a device to prevent the cleaning medium from splashing out from, for example, the cleaning cup.

[0003] Pet foot washing equipment commonly uses various cleaning methods, such as running water, running water combined with a roller brush, or still water combined with a roller brush. For example, running water cleaning often uses a spraying method to give the cleaning medium a certain impact force. When the cleaning medium with a certain speed is sprayed onto the animal's legs, it will cause disorderly splashing. Some of the cleaning medium will fly out of the mouth of the foot washing cup, which may wet the pet's body, the cleaner's clothes, or the floor, increasing the workload of subsequent work.

[0004] In comparison, pet paw cups are used only for cleaning a pet's single paw, so the opening is relatively small (pet paw cups are generally cylindrical cleaning tanks). Generally, the splashing of the cleaning medium can be reduced by deepening the cleaning tank. However, this method has a relatively narrow range of applications, and its applicability to animals is also relatively limited because it is more suitable for animals with relatively longer legs.

[0005] It should be noted that there are currently devices for washing the entire body of pets. These devices often employ a fully enclosed structure, making them unsuitable for washing only the animal's feet. However, considering the potential agitation of animals in enclosed environments, some implementations of these full-body pet washing devices require the animal's head to be exposed separately, making it easier to calm the animal during washing. Therefore, the top of the washing chamber in such foot-washing devices needs an opening for the head to protrude. A structure similar to a waistband can be installed at this opening. Specifically, a cylindrical structure made of a waterproof material such as rubber or plastic sheeting is used at the opening. A leather strap or rope is attached to the upper part of the cylindrical structure to tighten it. Once the animal's head protrudes, the strap is tightened, essentially sealing the opening (hereinafter referred to as the closing device). This method offers some reference value for preventing the cleaning medium from splashing out of pet foot washing devices. However, no pet foot washing devices currently use this configuration. The reason is that while the cylindrical shape is relatively easy to use for animal necks, it's less effective for animal legs. Animal legs vary greatly in thickness and generally have a wider top and narrower bottom, while the neck is the opposite, typically narrower at the bottom and wider at the top. Therefore, sealing with a constricting device is less effective for the legs. Furthermore, materials like plastic sheets and rubber sheets have poor rigidity and are prone to collapsing. In actual use, the cylindrical shape can easily collapse into things like foot-washing cups, requiring manual removal from the relatively narrow cups, which is inconvenient.

[0006] While the closing device might have some practical value for pet foot-washing cups, in reality, if the closing device and the opening are not properly aligned during use, they can easily tear apart due to the animal's leg movements. Furthermore, when using pet foot-washing devices with integrated foot basins or multi-cup foot-washing systems, it is difficult to install the closing device in a fixed position due to the varying leg spacing (front and hind legs and left and right legs) among different animals. Summary of the Invention

[0007] In view of this, the object of the present invention is to provide an animal foot washing device suitable for washing the four feet of animals, which can effectively reduce or avoid splashing of the cleaning medium from the foot washing device.

[0098] In embodiments of the present invention, "animals" mainly refers to pets, but also generally refers to other animals whose feet need to be cleaned by the equipment, primarily animals with four limbs, such as dogs, cats, pet pigs, rabbits, alpacas, etc.

[0099] Unlike traditional animal foot-washing cups that can only wash one animal foot at a time, the animal foot-washing device based on a relatively large number of embodiments of the present invention can wash all four feet of an animal simultaneously, but the possibility of only being able to wash one animal foot at a time is not excluded.

[0100] In the embodiments of this invention, "feet" is used to refer to the claws, hooves, etc. of animals. It should also be noted that in practical applications, for example, traditional commercially available pet foot-washing cups actually wash the pet's lower legs as well, but this does not affect the definition of a pet foot-washing cup. Similarly, for animal foot-washing devices, even if they contain the function of washing animal legs, they still fall under the category of animal foot-washing devices.

[0101] As for the cleaning tank 31, the part of the machine body that forms the cleaning tank 31 is a bottom cylindrical structure, that is, a barrel shape. In the embodiments of the present invention, rectangular tanks are the main type, while the cleaning tanks 31 provided by traditional animal foot washing equipment are mostly circular barrel structures.

[0102] When using rectangular grooves, rounded rectangular grooves are preferred.

[0103] In addition, Figure 11 and Figure 12 In the illustrated structure, the cleaning tank 31 can be represented as a variation of a rectangular tank, with its two long walls forming an arc-shaped structure, or in other words, constituting an arc-shaped wall. The arches of the two long walls are oriented in opposite directions, thus forming... Figure 11 and Figure 12 The cleaning tank 31 is relatively wide in the middle and relatively narrow at both ends.

[0104] Regardless of the type of cleaning tank 31, its opening is always at the top of the cleaning tank 31; therefore, at least in animal foot washing equipment, the top and bottom are fixed.

[0105] As mentioned earlier, the cleaning tank 31 with a rectangular groove structure is mainly used to clean the four feet of an animal at the same time. The animal's body length is generally greater than its body width. Therefore, the opening of the cleaning tank 31 has a long side and a short side.

[0106] Furthermore, the longer side corresponds to the animal's body length, thus determining the front and back direction, also known as the longitudinal direction, length direction, or head-to-tail direction. Correspondingly, the shorter side corresponds to the animal's body width, thus determining the left and right direction, also known as the transverse direction or width direction, and traditionally, the left and right direction is also called the lateral direction.

[0107] Currently, pet paw washing cups are generally used as small household appliances, which are limited to washing only one paw and are relatively small. However, in many embodiments of this invention, the provided animal paw washing device can be used as a household appliance, or as an appliance in pet shops or other service establishments. Because it needs to wash all four paws simultaneously, its overall size is relatively large. Therefore, in some embodiments, the cleaning medium can be supplied externally, and wastewater can be directly discharged through, for example, pipes.

[0108] In other embodiments, such as Figure 4As shown in the figure, the animal foot-washing device integrates a wastewater box valve seat 49, a wastewater box support 48, a clean water box valve seat 54, and a clean water box support 53, and correspondingly in... Figure 1 The middle part is equipped with a water purification box 11 and a wastewater box 12, which integrates the water purification source and the wastewater collection equipment.

[0109] It should be noted that in some embodiments, the animal foot washing device that washes only one foot at a time is not excluded, but is configured to have only one access port 79, which can be used only for washing a single foot, and thus can be adapted to, for example, improvements to conventional, relatively small pet foot washing cups.

[0110] Meanwhile, based on the concept of this invention, it is known that even with only one access port 79, it is still possible to clean multiple feet of an animal at the same time. Relatively speaking, under this condition, the overall concealment difficulty will be relatively high.

[0111] In addition, the mandatory and optional configurations have been mentioned above. For example, in some embodiments, the device for drying animal feet after washing can be an optional configuration. That is, drying can be achieved by animal foot washing equipment or by other drying equipment, such as manually drying the animal feet with a hair dryer after washing the animal feet.

[0112] Furthermore, the aforementioned components such as the water purification box 11 and the wastewater box 12 can also be considered as optional components.

[0113] Regarding the body, such as a traditional pet foot bath cup, which is usually used as a household appliance, the decorative features of the outer shell are required to be high. In the embodiments of the present invention, the animal foot bath device provided is also mainly used as a household appliance. Therefore, for the body, it is preferably equipped with a shell with good decorative features. At the same time, it can also be used as a functional component in many embodiments, mainly protecting the parts, compartments, etc. housed therein, or directly forming a cavity or other functional part.

[0114] In some embodiments, a portion of the housing structure is further configured to accommodate the mounting of the components, for example... Figure 5 The positioning cylindrical buckle 33 illustrated herein can be integrally formed with the housing portion and is used to support and connect the cleaning tank 31.

[0115] In addition, for ease of assembly and disassembly, the housing can have multiple parts, for example... Figure 1 The housing 2 and housing 4 shown can be fastened by means of a single-sided buckle, or by means of a fastener connection structure, such as using screws or bolts.

[0116] In comparison, snap-fit ​​joints are easier to create a smoother appearance and are more suitable for assembling household appliances.

[0117] Among them, housing 2 is Figure 5 The illustrated structure has a base plate 32, which can have a plurality of legs, such as Figure 5 The footrest 59 is shown in the figure. Casters can also be installed at the location of the footrest 59. The casters can be fixed wheels or swivel wheels to facilitate the movement of the animal foot washing device.

[0118] The casters can be equipped with a locking mechanism to lock the casters after the animal foot-washing equipment has been moved into place, ensuring stability during use.

[0119] exist Figure 1 In the illustrated structure, a wheel 1 is provided only at one end of the housing 2. The wheel seat of the wheel 1 extends obliquely downward from the lower part of that end, so that the wheel 1 can be separated from the ground in a flat state. When the other end of the housing 2 is lifted, a virtual hinge shaft is formed at the end where the wheel 1 is located. As the housing 2 is gradually lifted, the wheel 1 with the wheel seat set at an angle will contact the ground. At this time, the bottom plate 32 of the housing 2 is separated from the ground. The other end of the housing 2 is lifted further upward to ensure that the housing 2 is fully separated from the ground, so as to facilitate the dragging of the animal foot washing device by means of the wheel 1.

[0120] In addition, when an animal foot-washing device is designed to wash all four of an animal's feet at the same time, its height will be much smaller than its length. Therefore, in a more preferred embodiment, the animal foot-washing device should be designed to be stored upright.

[0121] Furthermore, in Figure 1 In the illustrated structure, an auxiliary support 14 is provided at one end where the wheel 1 is located. The auxiliary support 14 is centrally located at the end of the figure. In other embodiments, there may be two auxiliary supports 14, which are set separately on the left and right sides, so as to have a relatively large span to improve the stability of the support.

[0122] In addition, for the auxiliary support 14, a rubber block can be provided on the side that contacts, for example, the ground, to improve the anti-slip ability and also effectively prevent the shell made of, for example, plastic material from being scratched when it contacts the ground after being erected.

[0123] In addition, in some embodiments, when the animal foot washing device is placed upright, the auxiliary support 14 can be provided in three places, and the three auxiliary supports 14 can be arranged in an isosceles triangle. While improving the stability of the support, it also makes the support plane formed by the three auxiliary supports 14 lower than the lowest edge of the shell at this time, so that the shell is separated from the ground and avoids wear or scratches that may occur to the corresponding shell parts.

[0124] Furthermore, the support heights of the three auxiliary supports 14 are preferably different when the animal foot washing device is erected. For example, the three auxiliary supports 14 are arranged in an isosceles triangle. The support height of the auxiliary supports 14 at the two vertices of the base of the isosceles triangle can be relatively high. This allows the animal foot washing device to lean slightly against, for example, a wall after being erected, so that all three auxiliary supports 14 are in contact with the ground. The animal foot washing device leans slightly against, for example, the wall it is attached to after being erected, thus making its overall stability relatively good.

[0125] It should be further explained that if there are multiple auxiliary supports 14, the storage state of the animal foot washing device can be independent of any other object, such as not leaning against a wall, but forming a vertical storage state by relying closely on the support of the auxiliary supports 14.

[0126] For ease of description, the end where the auxiliary support 14 is located will be referred to as the front end in the following text. It should be understood that this description is only for convenience and does not constitute a specific limitation on the animal foot washing device based on the embodiments of the present invention. It should be understood that the auxiliary support 14 is itself an optional structure, and for an animal foot washing device, for example, with only a single access port 79, as mentioned above, it can be used for washing a single animal foot, and can be configured as a smaller animal foot washing device, with less requirement for whether it is placed upright.

[0127] In addition, in a preferred embodiment of the invention, the end where the auxiliary support 14 is located is also, for example, the end where the control panel is located. However, the control panel can also be located at the other end or side of the animal foot-washing device.

[0128] In contrast, more conventionally, the side where the control panel is located is usually called the front side, but as mentioned earlier, defining the front side is mainly for descriptive purposes rather than for specific limitations.

[0129] The body may consist of only a shell, but in more embodiments the shell is part of the body rather than the entirety of it.

[0130] The cleaning tank 31, as a fixture on the animal foot washing equipment, can be formed together with the body during manufacturing, or it can be a separately manufactured tank-shaped component assembled onto the base of the separately formed body.

[0131] exist Figure 5 In the illustrated structure, the body includes a base shell 2 and a casing 4, wherein the casing 4 and the washing tank 31 can be an integral structure or an assembly of separate manufacturing units. In a more preferred embodiment, the washing tank 31, as a separately molded component, can be mounted on, for example, the base shell 2 during the assembly of the animal foot washing device and connected to the casing 4.

[0132] In a preferred embodiment, the housing 4 and the cleaning tank 31 can be integrally injection molded to facilitate overall sealing, and then installed as an assembly on the housing 2.

[0133] The cleaning tank 31 is a tank-shaped component that is suitable for holding cleaning media such as water, with its opening facing upwards. The opening is called the tank opening, which is simply referred to as the opening for ease of description.

[0134] It should be understood that static soaking alone cannot effectively clean animal feet. Therefore, animal feet should be cleaned by either rinsing or spraying with a dynamic cleaning medium, or by brushing with a roller brush 27, or by a combination of both. However, in either case, water will splash, which may cause some of the splashed water to spray out from the mouth.

[0135] In view of this, in embodiments of the present invention, a shielding component is provided as a necessary configuration. This shielding component has two technical requirements: one is to minimize the impact on the animal's feet entering and exiting the cleaning tank, and the other is to effectively reduce or prevent the cleaning medium from splashing out of the opening. Therefore, the shielding component is disposed at the upper end of the cleaning tank 31 to shield the opening.

[0136] It should be noted that the use of covering parts does not preclude the use of other accessories, such as pre-attached sheet-like auxiliary covering parts to the animal's legs.

[0137] It should also be noted that shading does not require achieving complete avoidance under ideal conditions.

[0138] In addition, the shielding components can be fixedly installed to the body. If a fixed installation is used, it should be based on a detachable connection, such as using bolts, fastening, or a combination of multiple connection methods.

[0139] The main body of the shielding component is a plate-shaped part. Fixing plate-shaped parts is one of the easiest fixing methods to achieve in the mechanical field. The conventional fixing method is to have several screw holes distributed on the edge of the shielding component and use screws to fix it to the machine body.

[0140] Because the shielding components are located on the upper side of the machine, relative positional stability can be achieved based on gravity, and... Figure 3 In the illustrated structure, the upper end of the body is also provided with a stop 25, which is a concave stop, so that the main body of the shielding component, i.e. Figure 1 The cover plate 5 shown in the figure is housed therein and has good stability. Therefore, in some implementations, the shielding component and the body can simply be supported. Considering the stability of the position, positioning can be achieved using only a positioning pin or the aforementioned stop 25.

[0141] If connectivity is considered, a T-shaped latch, commonly used on doors and windows, can also be used for connection. Accordingly, the front end of the shielding component is pivotally connected to the upper front part of the body, while the rear end of the shielding component is provided with the T-shaped latch, and the rear end of the body is provided with a corresponding latch body for the T-shaped latch.

[0142] Regarding the aforementioned pivot connection between the shielding component and, for example, the front end, it can be a loose hinge. For instance, the front end of the shielding component has two protrusions or lugs, and a positioning hole is provided on the front side of the body. After the protrusions or lugs are inserted into the positioning hole, a loose fit is formed, allowing the other end of the shielding component to be lifted or lowered. After the rear end of the shielding component is lowered, it is connected to the body using, for example, a T-lock. Its front end is limited by the positioning hole, thus ensuring the overall assembly reliability.

[0143] exist Figures 1-3 In the illustrated structure, the rear end of the cover plate 5 included in the shielding assembly is connected to the rear end of the housing 4 included in the body by a single-sided buckle 19, and the rear end of the cover plate 5 is provided with a first lifting handle 7 to facilitate the overall opening and closing of the shielding assembly.

[0144] In a preferred embodiment, the single-sided buckle 19 is located within a groove for a more aesthetically pleasing overall appearance. For example... Figure 3 The buckle groove 18 shown is used to accommodate a single-sided buckle 19. The rear edge of the single-sided buckle 19 can protrude 2~8mm from the rear edge of the buckle groove 18 for easy operation.

[0145] The same configuration can also be applied to, for example Figure 1 and Figure 3 The hatch 10 shown has its rear end pivotally connected to the fuselage, while its front end is connected to the front end of the shell via, for example, a single-sided snap-fit ​​connection.

[0146] The overall disassembly and assembly of the shielding components facilitates the overall cleaning of the cleaning tank 31 and the maintenance of the internal components of the cleaning tank 31.

[0147] As mentioned earlier, the main body of the shielding component is a plate, such as Figure 1 The cover plate 5 shown in the figure is compared with Figure 1 and Figure 3 The cover plate 5 completely covers the opening of the washing tank 31. The cover plate 5 has two sets of two access ports 79 each, for a total of four access ports 79. The cover plate 5 also has some holes around the access ports 79, mainly to accommodate the configuration of animal leg drying equipment in some embodiments, which is an optional structure.

[0148] In addition, regarding the cover plate 5, if there is only one intervention port 79, it can be directly formed on the cover plate 5. However, if there are multiple intervention ports 79, considering the adjustability of the spacing between the intervention ports 79, a configuration is adopted in which, for example, the first water curtain 6 and the second water curtain 8 are installed on the cover plate 5, so as to facilitate the construction of a spacing adjustment structure or mechanism.

[0149] If the holes used for ventilation are relatively small, water will not splash out from these holes.

[0150] for Figure 11 and Figure 12 In the illustrated structure, only one intervention port 79 can be configured.

[0151] Similarly, in Figure 10 In the illustrated structure, a configuration of two access ports 79 can be merged into one access port 79, thus providing two access ports 79 on a single shielding component.

[0152] In summary, the number of interventional ports 79 can be one, two, or four.

[0153] Furthermore, as mentioned above, the animal foot-washing device based on the concept of this invention can be used to wash only one foot of the animal at a time. Therefore, the aforementioned example with only one access port 79 can be used to improve, for example, a traditional pet foot-washing cup, and can also be used as... Figure 11 and Figure 12 As shown, even with only one access port 79, it can be used to clean all four of an animal's feet at the same time.

[0154] Considering different applicable scopes, for ease of description, the animal foot washing device with two intervention ports 79 is referred to as the first configuration. In this case, each intervention port 79 can be used for the intervention of a pair of animal legs, so the two intervention ports 79 can meet the washing of all four feet of the animal.

[0155] If there are four intervention ports 79, then each intervention port 79 corresponds one-to-one with an animal leg. Figures 8-10 In the illustrated structure, every two access ports 79 form a group, thus forming two groups.

[0156] However, in some embodiments, the animal foot washing device is configured with four access ports 79, each of which can be relatively independent. For ease of description, when an animal foot washing device has four access ports 79, the animal foot washing device with two access ports 79 in pairs is referred to as the second configuration, while the animal foot washing device with four independent access ports 79 is referred to as the third configuration.

[0157] Furthermore, for the first to third configurations with multiple access ports 79, in order to meet the needs of cleaning the feet of animals of different sizes with one machine, the shielding component is adapted with an adjustment structure or mechanism for adjusting the spacing of the access ports 79.

[0158] When the aforementioned adjustment structure or mechanism exists, the shielding of the space between the intervention ports 79 needs to be considered. Therefore, the shielding component should include a first shielding structure that shields the space between the intervention ports 79.

[0159] The first shielding structure may be included in the intervention port component (hereinafter referred to as the intervention port portion) having the intervention port 79, such as an annular base plate constituting the intervention port portion. It may also be a separately configured shielding component or other components such as the cover plate 5, such as a bellows cover or other first shielding structure connected between the two intervention ports portions.

[0160] In some embodiments, the access port 79 has a second shielding structure with an array of elastic strips. When an animal's foot steps in, the array of elastic strips expands and enters the cleaning tank 31. The retraction of the elastic strips reduces the flow gaps caused by the expansion of the strips in the animal's leg, thereby reducing splashing of the cleaning medium.

[0161] The second shielding structure is applicable when there are one, two, or four intervention ports 79. In some specific embodiments, such as when there are four intervention ports 79, the number of animal legs corresponds one-to-one with the number of intervention ports 79. In this case, the intervention ports 79 can adopt the second shielding structure as described above, or other shielding structures can be adopted, such as the closing device with a flexible tube-adapted closure structure described in the background section.

[0162] In addition to the implementation described in the background section, the part used to achieve the closure can also be an elastic band (e.g., a rubber strip set at the opening of a flexible tube), which can adapt to the thickness of the animal's leg.

[0163] While using cable ties, belts, or other methods to tighten the straps manually is slightly more cumbersome, it offers better reliability.

[0164] Regarding the flexible cylinder, waterproof materials such as plastic film or polyethylene film can be used, as well as relatively expensive rubber diaphragms, or materials with relatively good water affinity such as cotton or linen. Rubber diaphragms, on the other hand, have a certain degree of elasticity and do not require pre-formed pleats. Plastic films and cotton, however, require pre-formed pleats or allowances to accommodate the expansion or contraction of the flexible cylinder opening.

[0165] Regarding the shape of the intervention port 79, it is necessary to consider that the size of the animal's legs, including the feet, is larger in the front-to-back direction than in the left-to-right direction. Therefore, when the intervention ports 79 correspond one-to-one with the animal's legs, the size of the intervention port 79 in the front-to-back direction is preferably larger than its size in the left-to-right direction. However, if four intervention ports 79 are configured in groups of two, the intervention ports 79 should have a relatively large size in the direction in which the two intervention ports 79 are arranged within the group. For example, if the first two intervention ports 79 are used as one group and the last two intervention ports 79 are used as another group, it is necessary to consider, for example, the span between the first two intervention ports 79 and the left and right legs of the animal. In this case, the front-to-back size of the intervention port 79 only needs to consider the front-to-back size range of the animal's front legs.

[0166] Alternatively, the intervention port 79 can be a rectangular port, a circular port, an elliptical port, or a rounded rectangular port with rounded ends and a rectangular body; wherein, the rectangular port is suitable for the first to third configurations, as well as the case with a single intervention port, the circular port is mainly suitable for the case with four intervention ports 79, and the elliptical port is also mainly suitable for the case with four intervention ports 79, and if an elliptical port is used, the major axis of the elliptical port is consistent with the anterior-posterior direction of the animal.

[0167] A round-headed rectangular opening can be understood as a variation of a rectangular opening, resulting in a relatively smooth outline of the intervention port 79, which provides a better experience for the animal.

[0168] If the intervention port 79 corresponds one-to-one with the animal leg, the circular port, oval port, and square port (a special case of the rectangular port) can be directly closed by a closing device, or the second shielding structure as described above can be used. If the second shielding structure is used, the elastic strip takes the intervention port wall as the mounting base and extends towards the centroid of the intervention port to form a ring array.

[0169] For example, in a circular array, the center of the array is also the center of the circular opening, and it is a regular circular array. Since a typical characteristic of a circle is that the space on the centrifugal side is relatively large and the space on the centripetal side is relatively small, the elastic strip can adopt a conical structure, that is, the centrifugal side is relatively thick or wide, while the centripetal side is relatively thin or narrow.

[0170] In some embodiments, the elastic strips can also be cylindrical bodies of equal diameter or sheet bodies of equal width. Elastic or non-elastic films are used to connect the elastic strips. When using a non-elastic film, pleats or allowances need to be pre-made to ensure controllable deformation. In these embodiments, the number of elastic strips can be relatively small. The aforementioned film connecting the elastic strips can produce an effect similar to, for example, fins, hereinafter referred to as webs. The number of elastic strips is reduced due to the interconnection of the webs, and the webs can effectively provide a shielding effect, which is also applicable in other embodiments of the present invention.

[0171] It should also be noted that, for example, a circular opening, the effective length of the elastic strip can be shorter than the radius of the circular opening. Under this condition, a circular opening with a second shielding structure will have a reserved opening in the center of the circular opening, which is more conducive to the intervention of the animal's leg. Moreover, the presence of the reserved opening will reduce the amount of deformation of the elastic strip when the animal's leg is involved, which will actually help to achieve splash prevention.

[0172] For the intervention port 79 with a rectangular or rounded rectangular structure, a ring array can also be used, except that it forms a rectangular ring instead of a circular ring. For distinction, the aforementioned ring array is referred to as the first array, while the array applicable to rectangular and rounded rectangular ports is called the second array.

[0173] In the second array, the elastic strips extend from a pair of long walls of the rectangular opening towards the opposing walls, forming a multi-row matrix with two columns. The number of rows depends on the length of the long walls of the rectangular opening. The elastic strips are either adjacent to each other in contact or have a relatively small gap, such as 0.3 to 3 mm. The effective length of the elastic strip here refers to the length extending from, for example, the wall surface of the long opening. The effective length of the elastic strip is less than or equal to half the width of the interventional opening 79, with the shorter portion being 0 to 1.5 mm.

[0174] In addition, for round-headed rectangular openings, the corresponding round head area is covered with a flexible sheet or a radially extending array of elastic strips. When using a flexible sheet for covering, it can be completely covered, mainly considering that the two ends of the round-headed rectangular opening (corresponding to the long side) are used less. At the same time, even if they are used, the flexibility of the flexible sheet can adapt to the movement of the animal's legs.

[0175] In some more specific embodiments, mainly applicable to two groups of intervention ports 79 or only one intervention port 79, the selected intervention port 79 is a rectangular port or a rounded rectangular port. In such applications, such as embodiments with only one intervention port 79, if it is also an embodiment that can clean all four feet of an animal at the same time, the size of the rectangular port will be relatively large, and the elastic strip will bend due to gravity. Therefore, the array of elastic strips suitable for this type of embodiment is called the third array.

[0176] In the third array, the two ends of the elastic strip can be connected to a pair of long openings or a pair of short openings, and arranged parallel to each other. Considering that when the elastic strip is connected to a pair of short openings, the deflection in the middle will be relatively obvious, which may result in a large gap between the elastic strips, under this condition, the elastic strips can be interconnected in the middle.

[0177] In some embodiments, such as Figure 9In the illustrated structure, each rectangular access port 79 extends an elastic strip from its long side wall. There are two sets of elastic strips, each set corresponding to a long side wall. The two sets of elastic strips are joined (not joined) at the middle of the rectangular port in the width direction, or there may be a slight gap, with the gap controlled between 0.3 and 3 mm.

[0178] Regarding the material of the elastic strip, silicone rubber is preferred. Silicone rubber is soft and has a texture similar to human skin, resulting in relatively good performance. Other types of rubber strips can also be selected for the elastic strip.

[0179] In addition, elastic strips can also be made of polyurethane, polyester, or thermoplastic materials. Thermoplastic materials are a common choice, distinct from thermosetting materials. Common thermoplastic materials include thermoplastic rubber and thermoplastic resins, such as polypropylene. If the plastic or thermoplastic material used has relatively high hardness, it can be made into a thinner strip or a hollow elastic strip to achieve better elasticity. When selecting materials, those with relatively good toughness and a relatively soft texture should be chosen.

[0180] Alternatively, bristles can be used, such as bundles of animal hair, which can be inserted into the oral wall of the intervention port 79 using a splicing method.

[0181] For other types of elastic strips, they can also be installed on the wall of the intervention port 79 using a plug-in method. The plug-in method is mostly an interference fit or interference fit profile connection, which facilitates quick replacement.

[0182] When a jet of liquid impacts an animal's foot or leg, the splash will have a relatively obvious diffuse reflection characteristic. As for the elastic strips, even if there are some gaps between them, it will not cause too much liquid to fly out. Therefore, in a more preferred embodiment, the elastic strip is a tapered strip that gradually tapers from the connecting end to the overhanging end or a variable diameter body with multiple segments, wherein the diameter between the multiple segments of the variable diameter body gradually decreases from the connecting end of the elastic strip to the overhanging end.

[0183] The connecting end of the elastic strip refers to the end where the elastic strip connects to the wall of the intervention port 79, while the cantilever end is the other end of the elastic strip.

[0184] The aforementioned connection method often gives the elastic strip a certain degree of rotational capability. As the elastic strip is used for a long time, it will bend downwards. By rotating the elastic strip, the installation angle of the elastic strip can be changed. For example, changing the installation angle by 180° will cause the downwardly bending elastic strip to flip over, thereby improving the overall service life.

[0185] Regarding the density of the elastic strips, in some embodiments, the second shielding structure constructed solely by the elastic strips, as described above, is relatively expensive and may not necessarily provide better shielding. In other embodiments, the elastic strips can be arranged relatively sparsely, with adjacent elastic strips connected by a flap. For details on the flap, please refer to the previous description of the web members; it will not be repeated here.

[0186] The second shielding structure constructed using this method with webbed parts has a relatively low cost, and the flap opens when the elastic strip is pulled down (the legs are pulled down), thus playing an auxiliary or primary shielding role.

[0187] Similarly, the flap can be made of elastic membrane or non-elastic membrane with reserved tension allowance. For example, non-elastic membrane with reserved tension allowance, such as a structure with reserved pleats, can be seen in corrugated pipes, accordion covers, and umbrellas, which give relatively large expansion and contraction space to materials that are originally lacking elasticity based on certain folds. Based on this, those skilled in the art can determine the selection of materials for non-elastic membrane and the structural configuration that is suitable for the purpose of this invention without creative labor.

[0188] In contrast, when a flap is used, the main function of the elastic strip changes from shielding to support, thus forming a skeleton. However, the material selection is still mainly based on relatively soft materials such as silicone.

[0189] As mentioned above, the first shielding structure is mainly used to shield the space between the intervention ports 79 when adjusting the spacing between them.

[0190] As a preferred option, a first shielding form, referred to as the first shielding structure, is wherein the intervention port portion having the intervention port is connected to the adjacent intervention port portion in the adjustment direction using a flexible diaphragm, an elastic diaphragm, or a bellows cover. The flexible diaphragm is mainly constructed of materials with non-elastic properties, such as fabric. It should be noted that everything has elasticity, but macroscopic elasticity refers to materials whose primary function is elasticity. For example, although some fabrics have good elasticity, cotton fabric is generally considered to be non-elastic, or in other words, a material whose primary function is not elasticity.

[0191] The elastic material can be referred to with reference to the definition and technical parameters of an elastomer. For example, its specification is defined as a material that undergoes large deformation under stress and quickly recovers its approximate initial shape and size after the external force is removed. Although this definition is a general one, it is clear to those skilled in the art and will not be elaborated here.

[0192] Regarding the first form of shielding, there is another good option, namely the accordion cover. The accordion cover is also a component made of non-elastic materials, such as plastic (similar to plastic corrugated pipe) or stainless steel. Accordion covers are widely used in machining equipment and also have good adaptability in the embodiments of the present invention.

[0193] like Figure 8 and Figure 9 There is a need to adjust the distance between the first-level water curtain 6 and the second-level water curtain 8. If such adjustments are not made... Figure 10 The shielding plate 78 shown can be provided with a bellows cover, an elastic diaphragm or a flexible diaphragm between the first water curtain 6 and the second water curtain 8.

[0194] Regarding the second form of the first shielding structure, it is as follows: Figure 10 As shown, the intervention port with intervention port 79 has a shielding plate 78 in the adjustment direction, and when both have shielding plates 78, there is an interference avoidance structure between the adjacent shielding plates 78.

[0195] Regarding the interference avoidance structure, in some embodiments, an overlapping configuration is adopted. For example, the first shielding plate of the first water curtain 6 and the second shielding plate of the second water curtain 8 overlap vertically, and have adjustment capability within the overlapping range.

[0196] Additionally, in some embodiments, the cover plate 5 of the shielding assembly is provided with a shielding support plate, such as the first shielding plate of the first-level water curtain 6 and the second shielding plate of the second-level water curtain 8, which is supported on the shielding support plate for adjustment under conditions that do not affect the function of the access port 79 on the first-level water curtain 6. This can be seen as an example of a third shielding form or as an example of a second shielding form.

[0197] The specific configuration of the third shielding form is as follows: In this third shielding form, a shielding support plate is formed between the intervention ports 79 in the adjustment direction of the intervention port 79, and the intervention port 79 has a bottom hole corresponding to the intervention port 79 based on the separation of the shielding support plate; within the adjustment range of the intervention port 79, the projection of the intervention port 79 on the support plane of the shielding support plate is located in the bottom hole, and the intervention port portion with the intervention port is supported on the shielding support plate. It should be noted that the support here does not require complete support, only to meet the supporting function.

[0198] As mentioned above, in the third shielding form and some embodiments of the second shielding form, the presence of a shielding support plate provides auxiliary support for the interventional opening, thereby enabling the interventional opening to have better support rigidity.

[0199] In some embodiments, a guide pair is provided in the direction of adjusting the structure or mechanism to facilitate more precise adjustment of the position of the interventional opening.

[0200] It should be noted that, as Figure 8 The first-stage water curtain 6 shown in the diagram is essentially supported by the cover plate 5. The cover plate 5 has a secondary stop 77 at the part supporting the water curtain. The secondary stop 77 is a concave stop, and its periphery forms a constraint, allowing guidance at both ends of the first-stage water curtain 6. The guidance is provided by... Figure 8 The adjustable border 75 is shown in the figure.

[0201] Furthermore, regarding the guide pair, it is not necessarily required that it be in a guiding state in real time when adjusting the water curtain. In particular, for example, the first water curtain 6, which is fixed to the adjustment frame 75 by a plug-in method, can be placed directly at the target position after lifting the water curtain 6.

[0202] Furthermore, such as Figure 8 As shown, the secondary stop 77 is a concave stop, and there must be a certain amount of movement space on its end face. However, this does not mean that it needs to be locked after adjustment. Even in the working state, for example, the first level water curtain 6 is not required to be fixed in the left and right direction. When it is set to float in this direction, it can still meet the usage requirements. That is, when the animal is moving, at least in the left and right direction, the first level water curtain 6 can move left and right. Under this condition, the guide pair is a free movement pair in the direction guided by the guide pair, except for the constraint formed by the secondary stop 77.

[0203] The part of the secondary stop 77 that provides constraint is that it is a concave stop, so its sidewalls can provide constraint, while the end face can provide guidance and support for, for example, the first water curtain 6.

[0204] The other degrees of freedom of the free motion pair are preferably constrained.

[0205] Comparatively, it is more preferable to equip the guide pair with a locking device. Alternatively, the guide pair may be a free-moving pair in the adjustment direction, except for the intervention port stop constraint.

[0206] Furthermore, the guiding pair is either a first linear motion pair formed between the intervention port with the intervention port and the upper end of the body corresponding to the port, or a second linear motion pair formed between the intervention port and a linear guiding member installed or formed on the upper end of the port. For the latter, a linear guide rail structure can be used, that is, the linear guide rail constitutes a linear guiding member, and a second linear guiding pair is formed between it and a slider provided on, for example, the first water curtain 6.

[0207] Furthermore, a plate mechanism or set screw is provided for the second linear motion pair to lock in place after the interventional opening is adjusted.

[0208] Among them, the handle plate mechanism is a common locking mechanism in the guide rail guiding mechanism, which generally includes manual handle plate, hydraulic handle plate and pneumatic handle plate. In the embodiments of the present invention, a manual handle plate is preferred.

[0209] For the second linear motion pair, its adjustment is mostly stepless, but in some embodiments, the adjustment can be stepped, such as by having adjustment holes 76 arranged in the adjustment direction on the side wall of the secondary stop 77 that forms the concave stop. Figure 8 The adjustment holes 76 are evenly distributed on the adjustment frame 75 shown.

[0210] Accordingly, an adjustment hole 76 is adapted to the aforementioned one, such as Figure 7 As shown, the intervention port is provided with a pin to lock in place with the corresponding adjustment hole 76 after the intervention port is adjusted into position. Figure 7 The lever 71 shown is the operating handle of the lever. It should be noted that the lever is a type of pin, which is a common type of locking pin, and will not be described in detail here.

[0211] exist Figure 5 In the illustrated structure, the lower end of the cleaning tank 31 has a manifold bottom plate 67, and the bottom of the manifold bottom plate 67 is provided with a drain outlet, such as... Figure 5 The reflux port 69 shown is used to drain the waste cleaning medium.

[0212] The confluence base plate 67 is configured based on the natural property of water flowing downhill. In other words, it cannot be a completely horizontal flat plate, but can be an inclined flat plate. However, its starting point does not need to have a large slope, so the confluence base plate 67 can be directly used as a footboard 22. However, in a more preferred embodiment, the footboard 22 can be configured simultaneously, and the footboard 22 is arranged as horizontally as possible to improve the animal experience.

[0213] Regarding the placement of the footrest 22 within the cleaning tank 31, its main function is to support the animal's feet. It is located at the bottom or middle of the cleaning tank 31. The choice of the middle position is mainly due to the different individual animals. The appropriate support height can be selected according to different animals, which will be explained in detail below.

[0214] As for the pedal 22, it can be configured in the cleaning tank 31 in a supporting manner, while the manifold base plate 67 can provide a supporting structure or component, such as a cylindrical protrusion, without affecting the enrichment of sewage, which has little impact on the enrichment of sewage.

[0215] Alternatively, the support structure or components for the pedal 22 can also be provided by the wall of the cleaning tank 31. In some embodiments, the support provided by the tank wall and the support provided by the confluence base plate 67 can be provided simultaneously. The support provided by the tank wall is used to provide support for the periphery of the pedal 22, while the support provided by the confluence base plate 67 is used to support the interior of the pedal 22.

[0216] In addition, the confluence base plate 67 itself can provide support for the periphery and the interior of the pedal 22.

[0217] In addition, as mentioned above, considering the adjustability of the support height, the aforementioned support provided by, for example, the busbar base plate 67 can be understood as the basic support, and the additional supports used for height adjustment are referred to as additional supports.

[0218] Furthermore, the pedal 22 is preferably provided with permeable holes 80.

[0219] In addition, the water-permeable hole 80 can also form a hot air flow passage hole. If a hot air outlet is provided in the space below the pedal 22, the airflow formed can be blown upward through the water-permeable hole 80 that forms the hot air flow passage hole.

[0220] For example, a one-way valve can be installed at the hot air outlet to prevent sewage from flowing back into the hot air supply pipeline. After the sewage is drained, the hot air outlet can be used to supply air.

[0221] Furthermore, in a preferred embodiment, the upper and / or lower surfaces of the busbar base plate 67 are provided with reinforcing ribs 68, such as... Figure 5 As shown, a reinforcing rib 68 is provided on the lower surface of the busbar base plate 67 to improve the overall strength of the busbar base plate 67.

[0222] In some embodiments, if the upper surface of the busbar base plate 67 is provided with reinforcing ribs 68, the reinforcing ribs 68 are reused as the structure of the support portion.

[0223] To reduce the impact on sewage collection, the reinforcing ribs 68 on the upper surface of the confluence base plate 67 can be arranged in the direction of sewage flow, and the reinforcing ribs 68 form a confluence channel.

[0224] The following describes a configuration suitable for the support height of the pedal 22, referred to as the support method of the pedal 22 on the support. In some embodiments, it is referred to as the first support method, in which the pedal 22 is freely supported on the support. This is mainly to facilitate the replacement of the pedal 22, that is, to provide a set of pedals 22 with different support heights for an animal cleaning device, so as to replace the appropriate pedal 22 according to the different sizes of animals.

[0225] In some embodiments, the support method of the pedal 22 is referred to as the second support method, in which, for example... Figure 11 and Figure 12 As shown, the pedal 22 has a positioning hole with an axis perpendicular to the pedal surface on its edge, as shown in the pin hole 82. The support part is provided with a positioning pin 81 corresponding to the pin hole 82. The pedal 22 is supported on the support part and positioned on the positioning pin 81, so as to facilitate the quick replacement of pedals 22 of different heights. Furthermore, the cooperation between the positioning pin 81 and the pin hole 82 can effectively reduce or prevent the pedal 22 from shaking.

[0226] In some embodiments, the method for adjusting the support height of the pedal 22 is referred to as the third support method. In this third support method, the height of the pedal 22 itself is fixed, while an adjusting ring is provided between the pedal 22 and the support. By adjusting the number of adjusting rings of equal height or different heights, the pedal surface can be positioned at different depths in the cleaning tank 31. In these embodiments, the adjusting ring is similar to an adjusting shim, and its use is relatively convenient.

[0227] exist Figure 11 and Figure 12 In the illustrated structure, a method for adjusting the support height of the pedal surface is adopted, referred to as the fourth support method. In this illustrated structure, both surfaces of the pedal 22 are treads, and the pedal 22 has a corresponding cylindrical shell. The plate of the pedal 22 is located at one end of the cylindrical shell, and the other end of the cylindrical shell is a support flange, forming a bucket as a whole. The plate of the pedal 22 forms the bottom plate of the bucket. In this way, the support height of the pedal 22 will change when the pedal 22 is installed upright or in reverse.

[0228] Accordingly, in the fourth support method, the problem of interference needs to be considered. A given distance is left between the support surface of the support part and the busbar base plate 67 to avoid interference between the pedal 22 and the busbar base plate 67 when the pedal is installed in the forward or reverse direction.

[0229] In some embodiments, the tread surface of the pedal 22 is provided with protrusions for massaging the soles of the feet, or a foot pad with protrusions for massaging the soles of the feet is placed on the pedal 22.

[0230] exist Figure 5 In the illustrated structure, below the busbar base plate 67, the fuselage is provided with a first compartment, such as... Figure 5 The equipment compartment 59 shown below the manifold base plate 67 often requires a certain height to meet the piping requirements. If it is only used for piping, the space will be wasted. Configuring it as equipment compartment 59 or other functional compartments will make full use of the space.

[0231] In some embodiments, the first compartment is used for the primary function of pipe routing and / or wiring; and / or

[0232] The first compartment has a secondary function: a water return box.

[0233] exist Figures 1-4 In the illustrated structure, the clean water box 11 and the wastewater box 12 are located in other compartments, the first compartment is used for piping, while... Figure 11 and Figure 12 In the illustrated structure, the sewage box 12 constitutes the aforementioned return water box, which can be directly installed in the first compartment and is configured as a pull-out sewage box 12 with a side opening.

[0234] Furthermore, if piping is installed in the first compartment, the piping shall include at least a return water pipe connected to the drain outlet; if the return water box is located in the first compartment, the return water box shall directly connect to the drain outlet or be connected to the drain outlet through the return water pipe.

[0235] In a preferred embodiment, a first solenoid valve is installed on the drain port or return pipe to control the timing of drainage.

[0236] exist Figures 1-4 In the illustrated structure, the machine body has a main compartment on one side of the cleaning tank 31, and the side with the main compartment in the figure is the front side of the cleaning tank 31.

[0237] The main compartment is equipped with a clean water tank 11 and auxiliary cleaning components, including at least a detergent container, such as... Figure 1 The dispensing compartment 9 shown in the figure contains several containers for holding functional liquids such as cleaning agents and sterilizing solutions.

[0238] Accordingly, the machine body is also equipped with a water supply device adapted to the water purification box 11, such as... Figure 4 The water pump 52 shown is shown.

[0239] exist Figure 1 In the illustrated structure, the main compartment and the cleaning tank 31 are arranged in front and behind positions respectively, and the main compartment has a left-center-right structure; accordingly, the auxiliary cleaning assembly is located in the center of the main compartment, the clean water box 11 is located in one of the left and right positions, and a wastewater box 12 is provided in the other position.

[0240] The integration of the water purification box 11 and the wastewater box 12 facilitates the control of the water supply quality and also makes it easier to set up the location of the animal foot washing equipment. If the water source is connected to an external source through a pipe or wastewater is discharged, it will inevitably cause inconvenience in selecting the location of the animal foot washing equipment. However, in the embodiments of the present invention, the integration or non-integration of the water purification box 11 and the wastewater box 12 is optional.

[0241] Furthermore, in order to facilitate the placement and removal of the water purification box 11 and the wastewater box 12, a water purification box support 53 is provided at the bottom of the main compartment for cooperating with the water purification box 11; the water purification box support 53 is provided with a water purification box valve seat 54 for socketing and connecting with the water outlet provided at the bottom of the water purification box.

[0242] Similarly, if the sewage box 12 is integrated, the integration method of the sewage box 12 in the main compartment shall refer to the integration method of the aforementioned water purification box 11.

[0243] In addition, if there are multiple auxiliary materials for auxiliary cleaning, a mixer 50 is provided on the feed pipeline of the auxiliary cleaning component for mixing the supplied auxiliary materials.

[0244] Furthermore, the mixer 50 is connected to the water supply pipe of the water purification box 11 and outputs to the main water supply pipe.

[0245] To precisely control the amount of auxiliary material supplied, a metering pump is installed on the pipeline connecting the auxiliary cleaning component to the mixer 50, such as... Figure 4 The metering pump set 47 shown is illustrated.

[0246] As mentioned earlier, there are multiple options, or even a combination of options, for cleaning animal feet. One option is to install a roller brush 27 in the cleaning tank 31. Another option is to install a nozzle of a water spray cleaning device. Yet another option is to install an outlet of a wave-making device. Correspondingly, a roller brush drive mechanism is installed for the roller brush 27, a water spray cleaning device is installed for the nozzle of the spray cleaning device, and a wave-making device is installed at the outlet of the wave-making device.

[0247] The above three cleaning methods can be used in combination, such as using the water spray cleaning device with the roller brush 27, or using the water spray cleaning device with the wave generator, etc.

[0248] exist Figure 3 In the illustrated structure, the cleaning tank 31 is divided into four cleaning sub-chambers, while... Figure 11 and Figure 12 The illustrated structure is a single-cavity structure.

[0249] If a multi-cavity structure is adopted, the included cleaning sub-cavities correspond one-to-one with the intervention port 79; and in the case of a multi-cavity structure, the cleaning sub-cavities are interconnected or isolated from each other.

[0250] It should be noted that the connection between the pedal 22 and the space below it due to the presence of water permeable holes 80 does not represent the connection between the multiple sub-cavities when multiple cleaning sub-cavities exist.

[0251] Furthermore, regarding the wave-generating device, it is obviously only usable when there is a certain depth of cleaning medium in the cleaning tank 31. In other words, under this condition, the connection between each cleaning sub-chamber can be achieved based on the water-permeable hole 80, but such connection does not contribute to the cleaning for the purpose of this invention.

[0252] Furthermore, if the wave-generating device is not present, and water is used for cleaning, i.e., spraying, the falling cleaning medium flows away directly. Under these conditions, the cleaning tank 31 may not form a certain depth of cleaning medium, and the connection becomes even less valuable.

[0253] The connectivity is even more valuable when wave generation is needed. Based on the connectivity of the portion above the tread of pedal 22, the waves generated by wave generation can interfere with each other, which helps to clean the animal's feet more effectively.

[0254] Regarding wave-making equipment, commercially available wave-making equipment mainly consists of wave-making pumps 35, also known as flow pumps. These are commonly used in aquariums to create a flow environment that simulates natural water flow. In the embodiments of this invention, when configuring the wave-making pump 35, the portion of the cleaning tank 31 above the tread surface of the footrest 22 needs to have a certain depth of cleaning medium. Only under these conditions is the configuration of the wave-making pump 35 worthwhile. The water flow generated by the waves cleans the animal's feet.

[0255] like Figure 3 As shown, a wave-generating outlet 28 is provided on one side of the lower part of each cleaning sub-chamber. The clean water inlet 21 is mainly used for water supply, and a cleaning effect can also be generated during the water supply process. With the wave-generating outlet 28 configured, the main function of the clean water inlet 21 is to supply water.

[0256] Regarding the example of configuring the water inlet 21 as a nozzle, if the cleaning function is emphasized, the nozzles can be arranged vertically in a cleaning tank or cleaning sub-chamber of a single-chamber structure, or the nozzles can have the freedom to rotate in the vertical plane.

[0257] Regarding the number of wave-generating outlets 28 adapted to the wave-generating device, one can be set for each cleaning sub-chamber. If the power is insufficient, two can also be set. If arranged in a predetermined direction, the surging direction of the waves generated by multiple wave-generating outlets 28 should be superimposed.

[0258] Regarding the configuration of the roller brush 27, its roller brush shaft can be configured horizontally or vertically, forming either a horizontal or vertical axis. Either configuration is suitable for cleaning animal feet.

[0259] If the roller brush shaft is horizontal, the axial direction of the roller brush 27 is consistent with the front-to-back direction of the animal in the cleaning tank 31. Under this condition, the roller brush 27 can be set relatively long, so as to adapt to the cleaning of the feet of animals of different sizes without having to adjust the position of the roller brush 27.

[0260] exist Figure 11 and Figure 12In the illustrated structure, which is an animal foot-washing device with a single-cavity structure, there are three bearing seats 62 for supporting the roller brush shaft, and three roller brushes 27 are adapted thereto, one on each side of the animal (left, center, and right). In some embodiments, considering the complexity of the cleaning process, two roller brushes 27 may be configured, one on each side of the animal.

[0261] For the cleaning sub-tank, two or three roller brushes 27 can be set, and the rest is the same as above.

[0262] The roller brush 27 is installed in the cleaning tank 31 with support at both ends, and one end of the roller brush shaft 31 is connected to the power input shaft using a coupling 61.

[0263] A single power unit can be used to drive the roller brush shaft 31, and all roller brush shafts 31 can be rotated synchronously via a synchronizing mechanism. Alternatively, multiple power units can be configured, with each roller brush shaft 31 equipped with one power unit. The power unit is primarily an electric motor 60.

[0264] The simplest configuration of the synchronization mechanism is to use a gear set 43, in which gears with the same module and the same number of teeth mesh in sequence for transmission between adjacent shafts.

[0265] In some implementations, chain drive mechanisms can also be used to achieve transmission. These transmission methods are all conventional transmission methods in the mechanical field and will not be elaborated on here.

[0266] To facilitate cleaning of the cleaning tank 31, the roller brush 27 is installed inside the cleaning tank in a manner that allows for easy assembly. Preferably, the coupling 61 is assembled on the roller brush shaft in a spring-pin configuration; correspondingly, the roller brush shaft has side holes for the passage of the spring-pin configuration's paddles or paddle blocks.

[0267] The spring pin type coupling 61 is connected to, for example, a gear shaft by a profile connection or a flat key connection, and the assembly and disassembly of the brush shaft can be achieved by the disengagement and connection of the spring pin.

[0268] For the part with the gear shaft installed, the cleaning tank 31 needs to have a side hole in the corresponding position to allow for the intervention of the gear shaft, for example. Since it is a dynamic connection, in order to effectively reduce the overflow of the cleaning medium and protect the power part of the roller brush 27, a skeleton shaft seal is provided at the gear shaft to provide a relatively good dynamic seal.

[0269] Accordingly, for example, a gear shaft, it needs to be supported by, for example, a bearing housing 62, in order to give it the freedom of rotation.

[0270] As mentioned above, as an optional configuration, some animal foot-washing devices based on embodiments of the present invention may be equipped with a drying device. Further, the sidewalls and / or bottom walls of the washing tank 31 are provided with drying air outlets, such as... Figure 3 The first main hot air outlet 20 is provided on the rear wall of the cleaning tank 31 and the second main hot air outlet 30 is provided on the front wall of the cleaning tank 31.

[0271] Since gases have greater fluidity than liquids, a relatively large number of air outlets can be formed through pipeline configuration. Therefore, the configuration of the number and location of the main hot air outlets will not be elaborated here, and those skilled in the art can select and configure them according to design requirements.

[0272] Accordingly, animal foot-washing equipment is equipped with a drying component, such as... Figure 4 The first hot air assembly 36 and the second hot air assembly 55 shown are connected to the drying air outlet via pipes or ducts. The purpose of configuring multiple hot air assemblies is to facilitate air distribution. Furthermore, if there are relatively many air outlets, the proximity effect will be more pronounced. Configuring multiple hot air assemblies, under the condition of the same number of air outlets, prevents some relatively distant air outlets from having excessively low air pressure.

[0273] In a preferred embodiment, the roller brush 27 is also reused as a drying device. On one hand, its rolling motion helps to comb the animal's fur, thus facilitating rapid drying. On the other hand, a hot air outlet can also be provided on the roller brush 27. Accordingly, the roller brush shaft of the roller brush 27 is a tube shaft 63, and a secondary air outlet is opened on the side of the roller brush shaft, such as... Figure 3 The auxiliary hot air outlet 24 shown in the figure facilitates the brush 27 to comb the animal hair while drying it.

[0274] In a preferred embodiment, although the bristles 64 of the roller brush 27 are flexible, the bristles 64 can still be configured as a hollow structure with a secondary air outlet formed on the bristles 64; correspondingly, the cavity of the hollow structure is connected to the cavity of the tube shaft 63.

[0275] As a preferred configuration, the drying assembly includes a fan for supplying air, a heater for heating the air drawn by the fan, a second temperature sensing element for detecting the temperature of the supplied air, and a purifier for purifying the supplied air.

[0276] exist Figure 4 In the illustrated structure, for example, the first hot air assembly 36 is adapted with a first temperature detection element 37, and further adapted with a first plasma generator for purifying the gas. Hot air with a certain plasma concentration also helps to sterilize and disinfect the animal's feet.

[0277] In addition, a swing mechanism can be installed at the corresponding main hot air outlet to expand the drying range.
