Description

Technical Field

[0001] This utility model relates to the technical field of intelligent pet drinking equipment, and in particular to an intelligent wastewater draining water tray and a pet drinking machine that separates clean and dirty water. Background Technology

[0002] Pet water fountains are essential equipment in modern pet ownership, primarily providing convenient drinking water for pets. The water bowl, as the pet's drinking device, may contain debris such as hair and food scraps during drinking. Users need to change the water bowl regularly to maintain cleanliness and hygiene. However, users cannot constantly monitor the water quality. Therefore, water fountains that automatically clean the water bowl have emerged on the market. For example, patent CN120052277A discloses a pet water fountain that separates clean and dirty water. This fountain has a rotating water bowl connected to the housing, and the main board controls the rotation of the water bowl to automatically pour dirty water into a dirty water tank. However, since the entire water bowl is rotating and connected to the housing, the large rotation amplitude causes dirty water to easily splash around, failing to ensure a dry and clean environment around the pet water fountain. Utility Model Content

[0003] The present invention provides an intelligent wastewater tray and a clean and dirty pet water dispenser, which provides pets with a clean and hygienic drinking water source and a dry and clean drinking environment.

[0004] First aspect

[0005] This utility model discloses an intelligent sewage-discharging drinking water tray, comprising:

[0006] The tray body is provided with a water trough and a sewage discharge channel. The sewage discharge channel forms a drain outlet at the end connected to the water trough and a sewage discharge outlet at the end opposite to the drain outlet.

[0007] A control component is installed on the disc body. The control component includes a stepper motor, a rotating shaft, and a baffle plate. The output shaft of the stepper motor is fixedly connected to the rotating shaft and rotates synchronously with the rotating shaft around the axis of the rotating shaft. The baffle plate is fixedly connected to the rotating shaft and located below the drain outlet. Under the reciprocating rotation of the stepper motor, the baffle plate flips back and forth with the rotating shaft to cover or open the drain outlet.

[0008] In one embodiment, the disc body includes a first housing and a second housing, the first housing and the second housing are connected to form an installation cavity and a sewage discharge channel, the installation cavity is watertight from the drinking water tank, and the stepper motor is installed in the installation cavity.

[0009] In one embodiment, the drinking trough and the mounting cavity are located on opposite sides of the first housing. The first housing has a first annular locking block protruding around the drain outlet on the inner wall of the mounting cavity, and the second housing has a second annular locking block protruding around the drain outlet on the inner wall of the mounting cavity. When the first housing and the second housing are connected, the first annular locking block and the second annular locking block are connected to form the drain channel.

[0010] In one embodiment, along the axial direction of the rotating shaft, the first annular locking block and the second annular locking block form two opposing through holes at the connection position. The two through holes allow the two ends of the rotating shaft to pass through and rotate. After one end of the rotating shaft enters the mounting cavity, it connects to the output shaft of the stepper motor.

[0011] In one embodiment, the control component further includes a sealing ring fitted onto the outer wall of the rotating shaft and located between the mounting cavity and the drain channel.

[0012] In one embodiment, the baffle plate includes a baffle seat and an elastic pad protruding from one side of the baffle seat. When the drain is covered, the radial dimension of the baffle seat is greater than the radial dimension of the drain, and the radial dimension of the elastic pad is greater than the radial dimension of the drain. The elastic pad elastically covers the outer wall surface of the drain facing away from the drinking trough; or, the radial dimension of the end face of the elastic pad is smaller than the radial dimension of the drain, and the elastic pad is interference-fitted into the drain.

[0013] In one embodiment, during the flipping process of the baffle plate, the side wall of the baffle plate is always spaced from the inner side wall of the sewage channel to provide rotation space for the baffle plate.

[0014] In one embodiment, the control component includes a control motherboard and a driver chip integrated on the control motherboard. The input lead of the stepper motor is electrically connected to both the driver chip and the control motherboard. The driver chip acts as a driver and has the function of controlling direction switching. The driver chip is used to drive the reciprocating motion of the stepper motor.

[0015] In one embodiment, the drinking tray is equipped with a circulation pump, the input and output ends of which are both connected to the drinking trough; the output end of the circulation pump is in the form of a shower head or a nozzle and extends out of the bottom of the drinking trough.

[0016] Secondly, this application provides a pet water fountain that separates clean water from dirty water, comprising:

[0017] A water purification tank, which includes a water purification trough;

[0018] A wastewater tank is located outside the clean water tank, and the wastewater tank has a wastewater trough;

[0019] As described in any of the preceding embodiments, the intelligent sewage discharge drinking water tray has its side facing away from the drinking water trough covering the top of the sewage tank. The drinking water trough is connected to the sewage tank through the sewage discharge channel. The tray and the sewage tank are located on the same side of the clean water tank.

[0020] A power supply component is installed in the water-purified water tank in a watertight manner, and the power supply component is electrically connected to the input lead of the stepper motor;

[0021] A water pump is located in the water purification tank and electrically connected to the power supply component. The input end of the water pump is connected to the inside of the water purification tank, and the output end of the water pump extends out of the water purification tank and is located above the drinking water trough.

[0022] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0023] This utility model provides an intelligent wastewater draining tray and a pet water fountain with clean and dirty separation. The pet water fountain with clean and dirty separation includes an intelligent wastewater draining tray. When the water in the water trough becomes dirty, a stepper motor can be activated. Under the reciprocating movement of the stepper motor, the baffle plate rotates forward and backward with the rotating shaft to cover or open the drain outlet, thereby blocking or clearing the drain channel and realizing intelligent wastewater drainage in the water trough. In this application, only a stepper motor is used to control the forward and reverse rotation angle of the baffle plate. When the target rotation angle is reached, the stepper motor automatically cuts off the power without manual control, greatly improving the electrical safety of the entire product. On the other hand, this application can achieve the function of draining and cleaning the water trough through the cooperation of a baffle plate and a drain channel. The tray does not need to be rotated, which reduces the risk of water splashing and provides pets with a clean and hygienic drinking water source and a dry and clean drinking environment.

[0045] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] Reference Figure 1-3This application provides a novel intelligent wastewater tray 10, including a tray body 100 and a control component 200 installed on the tray body 100. The tray body 100 is provided with a water trough 110 and a wastewater discharge channel 120. The water trough 110 is used to hold water for pets to drink. The wastewater discharge channel 120 forms a drain outlet 121 at one end connected to the water trough 110 and a drain outlet 122 at the other end facing away from the drain outlet 121. Water soiled by the pet in the water trough 110 can be discharged from the water trough 110 through the wastewater discharge channel 120, and then clean water can be introduced into the water trough 110 to ensure the cleanliness and hygiene of the drinking water in the water trough 110. The control component 200 includes a stepper motor 210, a rotating shaft 220, and a baffle plate 230. The output shaft 211 of the stepper motor 210 is fixedly connected to the rotating shaft 220 and rotates synchronously with the rotating shaft 220 around the axis of the rotating shaft 220. The baffle plate 230 is fixedly connected to the rotating shaft 220 and located below the drain outlet 121. Under the reciprocating rotation of the stepper motor 210, the baffle plate 230 can cover or open the drain outlet 121 by rotating the shaft 220, thereby closing or opening the sewage discharge channel 120.

[0049] Here, the stepper motor 210 has an output shaft 211 and an input lead (not shown). The output shaft 211 serves as the mechanical output end of the stepper motor 210 and connects to the rotating shaft 220. The input lead serves as the electrical connection end of the stepper motor 210 and connects to an external driver. The driver can control the stepper motor 210 to perform reciprocating motion through a program, that is, drive the output shaft 211 to switch between forward and reverse rotation, thereby driving the rotating shaft 220 and the baffle 230 to rotate in both directions. It can be understood that the driver can be installed and fixed on the disk 100 in a watertight manner and directly electrically connected to the input lead of the stepper motor 210, or the driver can be used as an independent accessory and electrically connected to the input lead of the stepper motor 210 through the conductive structure 240.

[0050] Preferably, refer to Figure 3 In one embodiment, the driver is fixedly mounted on the disk body 100. The control component 200 includes a control motherboard 250 and a driver chip integrated on the control motherboard 250. The input lead of the stepper motor 210 is electrically connected to both the driver chip and the control motherboard 250. The driver chip acts as a driver and has the function of controlling direction switching. The driver chip is used to drive the stepper motor 210 to perform reciprocating motion. The control motherboard 250 is externally powered through a conductive structure 240. Optionally, the conductive structure 240 can be a conductive post, a metal spring, or a flexible wire, etc.

[0051] Preferably, in conjunction with reference Figure 3-5In one embodiment, the disc body 100 includes a first housing 130 and a second housing 140. The first housing 130 and the second housing 140 are mated to form a mounting cavity 150 and a drainage channel 120. The mounting cavity 150 is water-proof to the drinking trough 110. The stepper motor 210 is installed in the mounting cavity 150, which provides a water-proof mounting space for the stepper motor 210, serving to fix and waterproof the stepper motor 210. It should be understood that in other embodiments, the disc body 100 does not have a mounting cavity 150, and the stepper motor 210 can also be installed and fixed on the outer wall of the disc body 100 facing away from the drinking trough 110.

[0052] Preferably, continue to refer to Figure 3-5 In one embodiment, the drinking trough 110 and the mounting cavity 150 are respectively located on opposite sides of the first housing 130. The first housing 130 has a first annular locking block 131 protruding around the drain outlet 121 on the inner wall of the mounting cavity 150. The second housing 140 has a second annular locking block 141 protruding around the drain outlet 122 on the inner wall of the mounting cavity 150. When the first housing 130 and the second housing 140 are connected, the first annular locking block 131 and the second annular locking block 141 connect to form a drain channel 120. In this embodiment, Figure 5 The illustration shows that the two housings and two locking blocks are joined vertically along the depth direction of the drinking trough 110, and the sewage discharge channel 120 passes through the two housings. It should be noted that in other embodiments, the shape of the two locking blocks is not limited, and they can also be joined horizontally or at an angle to form the mounting cavity 150 and the sewage discharge channel 120; in another embodiment, the two locking blocks are not provided, and the sewage discharge channel 120 can be formed directly by connecting an external pipe, with the two ends of the pipe respectively sealed and connected to the drain outlet 121 and the sewage outlet 122.

[0053] Preferably, in conjunction with reference Figure 5 and Figure 6 In one embodiment, along the axial direction of the rotating shaft 220, the first annular locking block 131 and the second annular locking block 141 form two opposing through holes 160 at the connection position. The two through holes 160 allow both ends of the rotating shaft 220 to pass through and rotate. One end of the rotating shaft 220 passes through the through hole 160 into the mounting cavity 150 and is then fixedly connected to the output shaft 211 of the stepper motor 210. The design of the two locking blocks mating to form the through holes 160 facilitates the engagement and assembly of the rotating shaft 220 within the two through holes 160, thereby improving the ease of assembly of the rotating shaft 220. It should be noted that in other embodiments, the two through holes 160 are not necessarily located at the connection position of the two locking blocks; a hole can also be drilled directly in one of the locking blocks to form the through hole 160 for the rotating shaft 220 to pass through.

[0054] Preferably, in conjunction with reference Figure 3 and Figure 6In one embodiment, the control component 200 includes a sealing ring 260, which is sleeved on the outer wall of the rotating shaft 220 and located between the mounting cavity 150 and the drain channel 120. The sealing ring 260 is elastically sleeved between the outer wall of the rotating shaft 220 and the inner wall of the perforation 160 to improve the assembly compactness of the rotating shaft 220 at the perforation 160, prevent sewage in the drain channel 120 from entering the mounting cavity 150 (waterproof sealing function), and protect the stepper motor 210 in the mounting cavity 150. It should be noted that in other embodiments, the sealing ring 260 may not be required, and the rotating shaft 220 may be press-fitted into the perforation 160 using an elastic material, which can also achieve the waterproof sealing function.

[0055] Preferably, in conjunction with reference Figure 3 and Figure 7 In one embodiment, the baffle plate 230 includes a baffle seat 231 and an elastic pad 232 protruding from one side of the baffle seat 231. When the drain outlet 121 is covered, the radial dimension of the baffle seat 231 is larger than the radial dimension of the drain outlet 121, and the radial dimension of the elastic pad 232 is larger than the radial dimension of the drain outlet 121. The elastic pad 232 elastically covers the outer wall surface of the drain outlet 121 facing away from the drinking trough 110. There is elastic compression between the elastic pad 232 and the open end face of the drain outlet 121 to enhance the sealing of the drinking trough 110 at the drain outlet 121 and prevent the drinking trough 110 from leaking water. The baffle seat 231 has a certain degree of rigidity to support the elastic pad 232. Optionally, in another embodiment (not shown), the radial dimension of the end face of the elastic pad 232 is smaller than the radial dimension of the drain outlet 121. The elastic pad 232 is interference-fitted into the drain outlet 121 to enhance the sealing of the drinking trough 110 at the drain outlet 121 and prevent water leakage. It should be noted that in other embodiments, the baffle 230 can be made of elastic material to directly cover the outer wall of the drain outlet 121 or interference-fitted into the drain outlet 121 to achieve the water-proof function of the drinking trough 110; in other embodiments, providing a sealing layer to the drain outlet 121 can also achieve the water-proof function of the drinking trough 110.

[0056] Preferably, refer to Figure 7 In one embodiment, the radial dimension of the baffle plate 230 is smaller than that of the drain channel 120. During the flipping process of the baffle plate 230, the side wall of the baffle plate 230 and the inner side wall of the drain channel 120 are always spaced apart, which can reduce the contact friction damping between the two and provide sufficient rotation space for the baffle plate 230, ensuring the smooth flipping of the baffle plate 230. It should be noted that, provided that the driving force of the stepper motor 210 is large enough, the baffle plate 230 can also abut against the inner side wall of the drain channel 120 during the flipping process.

[0057] Preferably, combined with Figure 1 and Figure 3 In one embodiment, the water bowl 10 is equipped with a circulation pump 300. Both the input and output ends of the circulation pump 300 are connected to the water trough 110. The circulation pump 300 is electrically connected to the control motherboard 250 or electrically connected to an external power source through a conductive structure 240. When the circulation pump 300 is turned on, it circulates the water in the water trough 110 to maintain the vitality of the drinking water and increase the pet's interest in drinking. Additionally, the output end of the circulation pump 300 is in a shower-like configuration (e.g., a spray nozzle). Figure 1 The nozzle (as shown in the figure) or the nozzle state (not shown) extends out of the bottom of the water trough 110 to further enhance the pet's interest in drinking and improve the pet's mood. It should be noted that, without considering enhancing the pet's interest in drinking, the presence or absence of the circulation pump 300 is not limited in this application, nor is the shape of the output end of the circulation pump 300 limited.

[0058] Second aspect

[0059] Reference Figure 8-10 This application provides a pet water fountain 1 with clean and dirty water separation, including the aforementioned intelligent wastewater discharge water tray 10, clean water tank 20, dirty water tank 30, power supply component 40, and water pump 50. The clean water tank 20 has a clean water trough 21 for storing clean water. The dirty water tank 30 is located outside the clean water tank 20 and has a dirty water trough 31 for collecting and storing dirty water generated by the pet during drinking. The tray body 100 of the water tray 10 covers the wastewater tank 30 on the side facing away from the water trough 110. The water trough 110 is connected to the wastewater tank 31 through a wastewater discharge channel 120. The tray body 100 and the wastewater tank 30 are installed on the same side of the clean water tank 20. The power supply component 40 is waterproofed and located in the clean water tank 20 and electrically connected to the input lead of the stepper motor 210. Here, the power supply component 40 provides power or driving force to the stepper motor 210 (the driver can be located in the power supply component 40). A water pump 50 is located in the water purification tank 20 and is electrically connected to the power supply component 40. The input end of the water pump 50 is connected to the water purification tank 21, and the output end of the water pump 50 extends out of the water purification tank 20 and is located above the drinking trough 110. When the water pump 50 is started, the clean water source in the water purification tank 21 is driven to be introduced into the drinking trough 110 after passing through the input end and the output end of the water pump 50 for the pet to drink.

[0060] The intelligent wastewater draining water tray 10 provided by this utility model can activate a stepper motor 210 when the water in the water trough 110 becomes dirty. Under the reciprocating motion of the stepper motor 210, the baffle 230 rotates forward and backward with the rotating shaft 220 to cover or open the drain outlet 121, thereby blocking or opening the drain channel 120 and realizing intelligent wastewater draining operation in the water trough 110. In this application, the forward and reverse rotation angle of the baffle 230 can be controlled by only the stepper motor 210. When the target rotation angle is reached, the stepper motor 210 will automatically cut off the power without manual control, greatly improving the electrical safety of the entire product. On the other hand, this application can achieve the function of draining and cleaning the water trough 110 through the cooperation of a baffle 230 and a drain channel 120. The tray body 100 does not need to be rotated, which will not easily cause water splashing, providing pets with a clean and hygienic drinking water source and a dry and clean drinking environment. Furthermore, this utility model provides a pet water dispenser 1 that separates clean water from wastewater. The water tray 10 directly covers the opening of the wastewater tank 31. When the stepper motor 210 is started, the water in the water tray 110 can be introduced into the wastewater tank 31 through the sewage discharge channel 120.

[0061] It should be noted that in other embodiments, the drinking tray 10 of this application can cover the opening of any water tank to drain the water in the drinking tank 110, or the drinking tray 10 can be installed on the wall and the drainage channel 120 can be extended to the sewage tank by an additional water pipe to realize the drainage function.

[0062] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
