Description

Technical Field

[0001] This invention relates to the field of pet grooming equipment, specifically to a pet fur care device. Background Technology

[0002] Currently, pet grooming equipment is used to clean pets' fur. References can be made to Chinese invention patent publication number CN120391355A, "A Heat Exchange System for a Dual-Air Duct Pet Drying Box," and utility model patent publication number CN223080801U, "A Pet Fur Care Dryer." Some pet grooming equipment includes a shower head, such as the utility model patent publication number CN213281090U, "An Animal Washing Device." Pets such as cats and dogs typically have thick fur. After outdoor activities, their fur may contain a lot of debris, such as leaf fragments, twigs, or mud. When using a shower head to wash a pet, the water flow mainly passes over the outside of the fur, making it difficult to wash away the debris hidden inside. In other words, the existing pet grooming equipment's cleaning performance is insufficient and needs improvement. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pet fur care device that improves the pet cleaning performance of the pet fur care device.

[0004] The objective of this invention is achieved through the following technical solution.

The lifting motor assembly is installed on the top of the vertical frame, the vertical screw is rotatably connected to the vertical frame, the lifting nut is installed on the push-pull crossbar, and the vertical screw is screwed to the lifting nut. The lifting motor assembly drives the vertical screw to rotate.

[0009] Preferably, in the first position, the length of the brush bar of the lowest position is greater than the length of the brush bar of the uppermost position.

[0010] Preferably, the brush bar has a cylindrical portion and a conical portion. One end of the cylindrical portion is connected to the support rod, and the other end of the cylindrical portion is connected to one end of the conical portion. The conical portion is gradually reduced in size along the direction away from the cylindrical portion, and the cylindrical portions of several brush bars are sequentially connected to each other in the left-right direction.

[0011] Preferably, the end of the brush bar is provided with a brush bar spray hole.

[0012] Preferably, the water system includes an inlet tank, a wastewater heat exchanger, a heating tank, an electric heating pipe, a water pump, and a receiving trough. The pet channel is located on the upper side of the receiving trough. The wastewater heat exchanger is located inside the inlet tank. The electric heating pipe is located inside the heating tank. The heating tank is located below the inlet tank. The heating tank and the inlet tank are connected by corresponding pipes. The heating tank is connected to the receiving trough via a hot water drain valve. The inlet end of the water pump is connected to the receiving trough. The outlet end of the water pump is connected to one end of the wastewater heat exchanger via a heat recovery outlet valve.

Detailed Implementation

[0032] The present invention will now be further described with reference to the accompanying drawings.

[0033] The pet fur care device of the present invention, such as Figures 1 to 9 As shown, it includes a washing mechanism 1, a water system 3, and a pet passage 10 for pets to pass through from left to right. The pet passage 10 extends in a straight line in the left-right direction, meaning that both ends of the pet passage 10 can connect to the outside of the pet fur care equipment, such as... Figures 3 to 6 and Figure 14As shown, the washing mechanism 1 includes a brush 11 for brushing the pet 99. The brush 11 is arranged horizontally, that is, the brush 11 extends in the left and right direction. The brush 11 is located on one side of the pet channel 10. The water system 3 includes a water spray bar 31 for spraying water into the pet 99 in the pet channel 10. That is, the water spray bar 31 extends horizontally, that is, the water spray bar 31 extends in the left and right direction. The water spray bar 31 is linked to the corresponding brush 11. The washing mechanism 1 is provided with a lifting drive assembly 13. The lifting drive assembly 13 drives the brush 11 and the water spray bar 31 to move up and down.

[0034] The following is a brief explanation of the working principle of the pet fur care device of the present invention for washing and brushing pets: Figure 2 and Figure 14As shown, pet 99 can enter pet passage 10 from right to left and then exit pet passage 10 to the left, or pet 99 can enter pet passage 10 from left to right and then exit pet passage 10 to the right. Of course, pet 99 can stay inside pet passage 10. During the process of pet 99 passing through pet passage 10, or when pet 99 stays inside pet passage 10, lifting drive component 13 drives brush 11 to move up and down to brush pet 99, and water spray bar 31 sprays water onto pet 99 inside pet passage 10. Thus, brush 11 can part pet 99's fur, causing water spray bar 31 to spray water onto pet 99 inside pet passage 10. When water is sprayed onto the pet's body, it can more easily penetrate the pet's fur and reach the pet's skin. The water flow can then more effectively remove dust from the fur and skin. Furthermore, the brush 11 can directly scrape away debris such as leaf fragments, small twigs, or small clumps of mud hidden in the pet's fur. Thus, the brush 11 can directly scrape these debris away from the pet, or loosen the debris from the pet's fur. The debris can then be carried away from the pet by the water flow, thereby cleaning the pet more effectively. Therefore, this invention helps improve the pet cleaning performance of pet fur care equipment. Because the lifting drive assembly 13 can drive the brush 11 and the water spray bar 31 to move up and down, and the water spray bar 31 is linked to the corresponding brush 11, the brush 11 can move up or down with the corresponding water spray bar 31. This achieves a large-area spraying and brushing effect on the pet 99, and the spraying and brushing effects are applied to the pet 99 roughly simultaneously, allowing the spraying and brushing effects to be combined more effectively to improve the cleaning effect of the pet 99. Because the brush 11 and the water spray bar 31 extend in the left and right direction, it is beneficial to spray and brush the pet 99 in a large area in the left and right direction, so that the pet 99 can be cleaned while walking through the pet passage 10. Before cleaning the pet 99, the pet 99 is located outside the pet fur care device. After the pet 99 enters the pet fur care device from one end of the pet passage 10, because the pet passage 10 is open from left to right, the pet 99 can continue to walk forward (in the direction of the pet 99's vision) more intuitively. If the pet 99 becomes frightened, it can escape directly from the other end of the pet passage 10 to the outside of the pet fur care device. In other words, after the pet 99 enters the pet fur care device, because the pet 99 can easily see the exit (that is, the other end of the pet passage 10), the pet 99 may be less frightened, making it more willing to stay in the pet passage 10. After the pet 99 uses the pet fur care device of this invention multiple times, the pet 99's habit of the pet fur care device's cleaning and grooming operation will increase.

[0035] Furthermore, such as Figures 2 to 5 As shown, the pet passage 10 is equipped with a washing mechanism 1 on both the front and rear sides, respectively. Figure 14 As shown, the pet grooming equipment can groom the pet 99 located in the pet passage 10 from both sides (for the pet 99). Since the two sets of brushing mechanisms 1 can work independently, the grooming of the pet 99's left and right sides is quite flexible. For example, when one side of the pet 99's body is dirtier, the corresponding brushing mechanism 1 can work for a longer period. The brushes 11 of the two sets of brushing mechanisms 1 can be staggered vertically during operation, meaning that the brushes 11 of the two sets of brushing mechanisms 1 do not move up and down synchronously. Therefore, the water spray bars 31 of the two sets of brushing mechanisms 1 can also be staggered vertically. Figure 3 , Figure 7 and Figure 8 As shown, the washing mechanism 1 includes a vertical frame 14, which can be welded together from stainless steel rectangular tubes. The shape of the vertical frame 14 can be roughly cuboid. A water receiving tank 39 is located at the bottom of the pet fur care device of the present invention. A guide rod is fixedly installed inside the water receiving tank 39. The guide rod extends in the front-to-back direction. The vertical frame 14 is slidably connected to the guide rod in the front-to-back direction through corresponding linear bearings. The brush 11 and the water spray bar 31 are correspondingly installed on the vertical frame 14. The pet passage 10 is formed between the front and rear vertical frames 14. Figure 6 As shown, the pet fur care device of the present invention also includes a channel widening mechanism 2 for adjusting the width (in the front-to-back direction) of the pet channel 10. The channel widening mechanism 2 drives the upright frame 14 to move back and forth. For example, the upright frame 14 on one side of the pet channel 10 can be kept fixed, while the upright frame 14 on the corresponding other side of the pet channel 10 can be moved back and forth, thereby adjusting the width of the pet channel 10 in the front-to-back direction. Figure 6 As shown, in some embodiments, the width adjustment mechanism 2 includes a width adjustment motor assembly 21, a bidirectional screw 22, a front nut 23, and a rear nut 24. The bidirectional screw 22 is rotatably connected to the water receiving tank 39 and extends in the front-to-back direction. The output shaft of the width adjustment motor assembly 21 is driven to the rear end of the bidirectional screw 22 via a coupling. The front nut 23 is installed at the bottom of the upright frame 14 located at the front position, and the rear nut 24 is installed at the bottom of the upright frame 14 located at the rear position. The front nut 23 is screwed onto the bidirectional screw. The front part of rod 22 is screwed to the rear part of the double-ended screw 22 by a rear nut 24. The external threads at the front and rear of the double-ended screw 22 have opposite directions of rotation. Therefore, when the output shaft of the width-adjusting motor assembly 21 rotates in the forward direction, the double-ended screw 22 causes the two upright frames 14 to move closer together, narrowing the pet passage 10. Conversely, when the output shaft of the width-adjusting motor assembly 21 rotates in the reverse direction, the double-ended screw 22 causes the two upright frames 14 to move further apart, widening the pet passage 10. Figure 14 As shown, when the width of the pet 99's body (for the pet 99, the width referred to here is the width in the left-right direction) is large, the pet channel 10 can be widened accordingly by adjusting the width motor assembly 21. When the width of the pet 99's body is small, the pet channel 10 can be narrowed accordingly by adjusting the width motor assembly 21, so that the pet channel 10 can better fit the pet 99's body. Because the brush 11 and the water spray bar 31 are respectively set on the upright frame 14, and the pet channel 10 is formed between the front and rear upright frames 14, it is beneficial for the brush 11 and the water spray bar 31 to adapt to pets 99 with different body widths. The width of the pet channel 10 in the front-back direction can be approximately 20 cm to 40 cm. A limit switch can be set to limit the front-back movement range of the upright frame 14. The limit switch is electrically connected to the width motor assembly 21. Figure 7 As shown, the pet fur care device of the present invention includes a base 100, a water receiving tank 39 mounted on the base 100, and a crossbeam 101 extending in the left-right direction fixedly mounted on the base 100. The crossbeam 101 is located above the bottom of the water receiving tank 39, and a guide rod support 15 is mounted on the inner side of the water receiving tank 39. The guide rod passes through the guide rod support 15. Figure 6 As shown, the linear bearing installed at the bottom of the vertical frame 14 is located between the guide rod support 15 and the crossbeam 101 in the front-back direction, thereby limiting the front-back movement range of the linear bearing installed at the bottom of the vertical frame 14 to between the guide rod support 15 and the crossbeam 101.

[0036] Furthermore, such as Figures 3 to 5 As shown, the washing mechanism 1 includes a track 12, which includes a vertical track segment 121 and a longitudinal track segment 122. The lower end of the vertical track segment 121 is connected to the end of the longitudinal track segment 122 that is relatively close to the pet passage 10. That is, the longitudinal track segment 122 extends roughly in the front-to-back direction. The water spray bar 31 is located above the corresponding brush 11. The left and right ends of the water spray bar 31 are respectively slidably connected to the corresponding vertical track segment 121, as shown. Figure 5 and Figure 13 As shown, the brush 11 includes a support rod 111 and brush strips 112 for contacting the pet 99. The brush strips 112 are distributed along the left-right direction on the support rod 111 and are approximately perpendicular to the support rod 111. The brush strips 112 can be made of silicone rubber, giving them good soft elasticity. The support rod 111 can be made of stainless steel rectangular tubing. The left and right ends of the support rod 111 are slidably connected to corresponding tracks 12, meaning that tracks 12 are installed at the left and right ends of the frame 14. The brush strips 112 have a first position and a second position relative to the pet channel 10; in the first position, as shown... Figure 14As shown, the brush bar 112 extends into the pet passage 10, meaning the support rod 111 is located outside the pet passage 10. The support rod 111 is connected to the vertical track section 121. In other words, when the brush 11 is in operation, the support rod 111 slides up and down within the corresponding vertical track section 121. When the brush 11 is in the aforementioned first position, the brush bar 112 extends approximately in the front-to-back direction, allowing it to extend from the outside of the pet passage 10 into the pet passage 10, thus enabling it to contact the pet 99 within the pet passage 10. When the brush bar 112 brushes the pet 99, it can bend and deform elastically. Figure 4 and 5 As shown, in the second position described above, the brush bar 112 is located outside the pet passage 10, and the support rod 111 is connected to the longitudinal track section 122. At this time, the brush bar 112 is set to extend approximately in the vertical direction. That is to say, when the brush bar 11 is not in use, the support rod 111 of the brush bar 11 can slide down from the corresponding vertical track section 121 to the longitudinal track section 122, and then the support rod 111 slides away from the pet passage 10 along the longitudinal track section 122. Thus, the brush bar 112 on the support rod 111 is taken away from the pet passage 10 by the support rod 111. When the pet 99 has not yet entered the pet passage 10, the brush bar 11 can be slid to the longitudinal track section 122 to make the brush bar 11 leave the pet passage 10. When the pet 99 enters the pet passage 10, the brush bar 11 is prevented from obstructing the pet 99's movement. Afterward, the pet 99 can stay in the pet passage 10, and then the brush bar 11 can be slid to the vertical track section 121 to make the brush bar 11 enter the working state.

[0037] Furthermore, such as Figure 5 and Figure 14 As shown, several brushes 11 are arranged along the track 12. For example, each washing mechanism 1 has three rows of the above-mentioned brushes 11. The track 12 has a groove-shaped structure, and adjacent brushes 11 are hinged to each other. Specifically, as shown... Figure 5 As shown, connecting rods 114 are respectively installed at the left and right ends of the support rod 111. Pins are provided at both ends of the connecting rods 114 along the direction of the track 12. The ends of adjacent connecting rods 114 are hinged through corresponding pins, and each pin is coaxially rotatably connected to a roller 115. The rollers 115 are adapted to roll within the track 12, thereby connecting the three rows of brushes 11. When the brushes 11 slide along the track 12, the rollers 115 roll within the track 12. Figure 5As shown, the washing mechanism 1 includes a push-pull crossbar 113, which extends in the left-right direction and is fixedly connected to the water spray crossbar 31. Specifically, connecting rods are respectively provided between the left and right ends of the push-pull crossbar 113 and the outer walls of the left and right ends of the water spray crossbar 31. The connecting rods can be welded to the push-pull crossbar 113 and the water spray crossbar 31 respectively. The push-pull crossbar 113 is hinged to adjacent brushes 11. Specifically, the washing mechanism 1 is provided with a chain piece 116. One end of the chain piece 116 is hinged to one end of the connecting rod 114 at the end of the first brush 11 in the brush queue, and the other end of the chain piece 116 is hinged to the push-pull crossbar 113. The left and right ends of the push-pull crossbar 113 are respectively slidably connected to corresponding vertical track sections 121. Sliding bars are provided in the vertical track sections 121, and the sliding bars are installed and connected to the ends of the push-pull crossbar 113 and the ends of the water spray crossbar 31. Figures 3 to 5 As shown, the lifting drive assembly 13 includes a lifting motor assembly 131, a vertical screw 132, and a lifting nut 133. The lifting motor assembly 131 is mounted on the top of the upright frame 14. The vertical screw 132 is rotatably connected to the upright frame 14. Specifically, a support plate is mounted on the lower end of the upright frame 14, and the lower end of the vertical screw 132 is rotatably connected to the support plate. When the brush 11 is in the second position, the lower end of the vertical screw 132 is above the brush 11. The lifting nut 133 is mounted on the push-pull crossbar 113, and the vertical screw 132 is screwed onto the lifting nut 133. The lifting motor assembly 131 drives the vertical screw 132 to rotate. Therefore, when the vertical screw 132 rotates, it can drive the lifting nut 133 to move up and down, thus allowing the push-pull crossbar 113 to move up and down. When the brush 11 is in the second position, as... Figure 5As shown, the brush 11 queue is connected to the longitudinal track section 122, and the push-pull crossbar 113 and water spray crossbar 31 are connected to the vertical track section 121. The lifting motor assembly 131 drives the lifting nut 133 to move upward, thus causing the push-pull crossbar 113 and water spray crossbar 31 to move upward. The aforementioned slider moves upward along the vertical track section 121. The push-pull crossbar 113 drives the brush 11 queue from the longitudinal track section 122 to the vertical track section 121 through the aforementioned chain 116. The vertical track section 121 and the longitudinal track section 122 have an arc transition. Afterward, the brush 11 queue is driven to the vertical track section 121, and the roller 115 runs to the vertical track section 121. At this time, the brush 11 is in the uppermost position. This refers to the first brush 11 in the aforementioned brush queue 11. The water spray bar 31 is located above the corresponding push-pull bar 113. The brush 11 and the water spray bar 31 then move upwards synchronously. When the water spray bar 31 reaches its highest position (upper limit position), the lifting motor assembly 131 drives the vertical screw 132 to rotate in the opposite direction, thereby causing the brush 11 and the water spray bar 31 to move downwards synchronously. When the lowest brush 11 in the brush queue approaches the lower end of the vertical track section 121, the lifting motor assembly 131 drives the brush 11 and the water spray bar 31 to move upwards synchronously, causing the brush 11 to comb the pet 99 up and down, and the water spray bar 31 to spray the pet 99 back and forth. Figure 3 and Figure 5 As shown, the water spray bar 31 has a hollow structure, with its left and right ends closed. A water inlet pipe is located on the outer wall of the side of the water spray bar 31 facing away from the pet passage 10. Water spray holes 311 are formed on the side of the water spray bar 31 facing the pet passage 10. The diameter of the water spray holes 311 can be set to 1 mm to 2 mm. The water spray holes 311 are arranged in the left-right direction, so water sprays approximately in the front-back direction. Because the water spray holes 311 can move up and down, such as... Figure 14 As shown, when the horizontal bar spray nozzle 311 moves to the position of the pet 99, the water sprayed from the horizontal bar spray nozzle 311 can hit the pet 99. Since the pet 99 can walk within the pet passage 10, the water can fall on different parts of the pet 99's body. Similarly, the brush bar 112 can also brush different parts of the pet 99's body. Since several rows of brushes 11 are arranged along the track 12, it is beneficial for the pet 99 to receive a larger range of brushing effect, thereby improving the cleaning effect of the pet 99. Since the rows of brushes 11 brush the pet 99's fur up and down, the pet 99's fur can be made to move roughly up and down, making the pet 99's fur relatively orderly. When the pet 99 is finished being brushed, the lifting motor assembly 131 drives the push-pull horizontal bar 113 to move down to the lower end of the vertical track section 121. The push-pull horizontal bar 113 pushes the row of brushes 11 to the longitudinal track section 122 through the chain 116.

[0038] Furthermore, such as Figure 8 and Figure 14As shown, in the aforementioned first position, the length of the brush bar 112 of the lowest brush row 11 is greater than the length of the brush bar 112 of the relatively upper brush row 11. Figure 13 As shown, the length of brush bar 112 is the dimension "L". That is, when the brush array 11 is in working condition, the brush bar 112 of the lowest position in the brush array 11 is the longest. When the brush array 11 runs on the vertical track section 121, because the upper and lower ends of the connecting rod 114 are respectively equipped with rollers 115, and the rollers 115 are located in the groove-shaped track 12, the connecting rod 114 cannot rotate relative to the track 12. In other words, the brush bar 112 can remain approximately perpendicular to the track 12, so that when the brush array 11 runs on the vertical track section 121, the brush bar 112 extends approximately in the front-to-back direction. When the brush array 11 runs on the longitudinal track section 122, the brush bar 112 can change to a state of extending in the up-and-down direction. Figure 14 As shown, the fur on the left and right sides of the pet 99's torso is more likely to contact the brush bar 112, while the fur at the bottom of the pet 99's torso is relatively far from the support rod 111, making it less likely for the fur at the bottom of the pet 99's torso to contact the brush bar 112. However, because the length of the brush bar 112 at the lowest position of this embodiment is greater than the length of the brush bar 112 at the uppermost position of the brush bar 11, the longer brush bar 112 at the lowest position can extend closer to the bottom of the pet 99's torso in the middle position in the left-right direction (in... Figure 14 (From the visual direction), the longer brush bar 112 then moves upward, making it easier for the longer brush bar 112 to brush the fur at the bottom of the pet 99's body, which is beneficial for brushing a larger area of ​​the pet 99's body. However, when the longer brush bar 112 moves to the sides of the pet 99's body, the longer brush bar 112 will bend and deform significantly due to obvious interference with the pet 99's body. The elastic recovery force of the longer brush bar 112 will exert a large pushing force on the pet 99. Therefore, setting the length of the brush bar 112 of the relatively upper row of brushes 11 to be shorter can avoid the pet 99's body being pushed and pressed by the longer brush bar 112 over a large area due to the longer brush bar 112 of each row of brushes 11, which can relatively reduce the degree of discomfort of the pet 99.

[0039] Furthermore, such as Figure 13As shown, the brush bar 112 has a cylindrical portion 1120 and a conical portion 1122. One end of the cylindrical portion 1120 is connected to a support rod 111, and the corresponding other end of the cylindrical portion 1120 is integrated with one end of the conical portion 1122. The conical portion 1122 is coaxially arranged with the cylindrical portion 1120, and the conical portion 1122 gradually decreases in size along the direction away from the cylindrical portion 1120. Several (up to three) brush bars 112 have their cylindrical portions 1120 connected together in a left-right direction. Specifically, three brush bars 112 can be connected as a group, and the groups of brush bars 112 are spaced apart in the left-right direction. Figure 13 From the perspective of vision, because the outer diameter of the conical part 1122 gradually decreases from top to bottom, and the adjacent conical parts 1122 are separated from each other, the conical part 1122 is more likely to bend and deform elastically (including bending up and down and bending left and right). That is to say, the conical part 1122 is relatively soft. The main use of the conical part 1122 to contact the pet 99 is conducive to the pet 99 feeling relatively comfortable. The support rod 111 can be made of stainless steel rectangular tube. A long hole is machined on one side of the support rod 111. A retaining groove is formed on the outer side of the upper end of the assembly of several cylindrical parts 1120. The entire circumference of the long hole is engaged in the retaining groove. Because the brush strip 112 is made of silicone rubber, when the assembly of several cylindrical parts 1120 is inserted into the corresponding long hole, the assembly of several cylindrical parts 1120 can elastically contract and deform, thus squeezing the assembly of several cylindrical parts 1120 into the corresponding long hole. Since the cylindrical parts 1120 of several brush strips 112 are connected to each other in the left and right direction, the number of long holes can be reduced.

[0040] In some implementations, such as Figure 13 As shown, the brush bar 112 has a water spray hole 1121 at its end. That is, the water spray hole 1121 is located at the end of the brush bar 112 that is relatively far away from the support rod 111. A cavity can be formed inside the brush bar 112. The cavity extends along the brush bar 112, so the water spray hole 1121 can connect to the inside of the support rod 111, making the left and right ends of the support rod 111 closed. A water inlet is provided on one side of the support rod 111. Water is supplied to the support rod 111 through the water inlet, which can make the water spray hole 1121 spray water. That is, the tip of the brush bar 112 can spray water. When the brush bar 112 brushes the pet 99's fur, the brush bar 112 lifts the pet 99's fur, so that the tip of the brush bar 112 can get close to the pet 99's skin. Therefore, the water sprayed from the tip of the brush bar 112 can more easily reach the pet 99's skin, thereby improving the cleaning effect of the pet 99.

[0041] Furthermore, such as Figure 7 , Figure 11 and Figure 15As shown, the water system 3 includes an inlet tank 36, a wastewater heat exchanger 361, a heated water tank 37, an electric heating pipe 371, a water pump 38, and a water receiving trough 39. The upright frame 14 and the pet passage 10 are located on the corresponding upper side of the water receiving trough 39. Figure 2 As shown, side railings 102 are provided on the front and rear sides of the pet passage 10, and a bottom railing 101 is provided at the lower end of the pet passage 10. The bottom railing 101 is attached to the upper side of the crossbeam 101. Therefore, it can be understood that the two side railings 102 and the bottom railing 101 enclose the pet passage 10. The bottom railing 101 can support the pet 99 above the water tank 39, while the side railings 102 can restrict the pet 99's torso within the pet passage 10 in the front-to-back direction. The brush bar 112 is positioned corresponding to the gaps in the side railings 102, allowing the brush bar 112 to pass through the side railings 102. Figure 11 and Figure 15As shown, the wastewater heat exchanger 361 is installed inside the inlet tank 36, and the water electric heating tube 371 is installed inside the heating water tank 37. The heating water tank 37 is located below the inlet tank 36. The upper right end of the heating water tank 37 is connected to the bottom right end of the inlet tank 36 through corresponding pipes. The bottom left end of the inlet tank 36 is connected to a tap water pipe through a tap water inlet valve 301. The lower part of the heating water tank 37 is connected to the aforementioned water receiving trough 39 through a hot water drain valve 302. The inlet end of the water pump 38 is connected to the aforementioned water receiving trough 39. The outlet end of the water pump 38 is connected to one end of the wastewater heat exchanger 361 through a heat recovery outlet valve 305. The outlet end of the water pump 38 is connected to the spray bar 31 through a pet washing outlet valve 303. Because the heating water tank 37 is located at the rear of the pet passage 10 and the water receiving trough 39 is located at the lower side of the pet passage 10, the upper part of the heating water tank 37 is higher than the water receiving trough 39. The water heating element 371 can heat the water in the heating water tank 37. When it is necessary to clean the pet 99, first open the hot water drain valve 302. The warm water in the heating water tank 37 will flow down into the water receiving trough 39 by gravity. Tap water will automatically replenish the inlet tank 36. Then, the water in the inlet tank 36 will flow down into the heating water tank 37. After the water receiving trough 39 is filled with warm water, the water heating element 371 will stop working. Then, close the hot water drain valve 302. Because the inlet of water pump 38 is connected to the aforementioned water receiving tank 39, and water pump 38 is a centrifugal pump, the height of the pump body of water pump 38 is significantly lower than the liquid level in the water receiving tank 39. Therefore, the water in the lower part of the water receiving tank 39 can be pumped into the pump body of water pump 38 by water pressure (that is, to fill the pump 38). Opening the pet washing water outlet valve 303 allows water pump 38 to operate, pumping the water in the water receiving tank 39 to the spray bar 31. Then, the spray holes 311 on the spray bar 31 spray water onto the pet 99. Because the pet 99 is located in the pet passage 10, which is located above the water receiving tank 39, the spray... The water sprayed from the water bar 31 falls into the water tank 39, thus forming a warm water circulation. A water tank electric heating tube can be installed at the bottom of the water tank 39. A water tank temperature sensor is installed in the water tank 39. The water tank electric heating tube and the water tank temperature sensor are electrically connected to the control circuit. When the water tank temperature sensor detects that the water temperature in the water tank 39 drops to the set value, the control circuit controls the water tank electric heating tube to work. The water tank electric heating tube directly heats the water in the water tank 39, which can prevent the water sprayed on the pet 99 from being too cold. When the water tank temperature sensor detects that the water temperature in the water tank 39 rises to the set value, the control circuit controls the water tank electric heating tube to stop working.After the pet 99 is washed, the water in the receiving tank 39 can be drained. Then, the pet washing water outlet valve 303 is closed, and the heat recovery water outlet valve 305 is opened, causing the water pump 38 to start. The water pump 38 draws the residual warm water in the receiving tank 39 to one end of the wastewater heat exchanger 361. The warm water then flows through the wastewater heat exchanger 361. Since the wastewater heat exchanger 361 is located inside the inlet tank 36, which is connected to the tap water pipe, the water temperature in the inlet tank 36 will be lower. Therefore, the heat of the warm water in the wastewater heat exchanger 361 is transferred to the tube wall of the wastewater heat exchanger 361. The tube wall of the wastewater heat exchanger 361 heats the water in the inlet tank 36, thus achieving heat recovery of the wastewater in the receiving tank 39, which is beneficial for energy saving. Figure 15 As shown, one end of the drain pipe 391 is connected to the bottom of the water receiving tank 39, and the drain pipe 391 is connected to the water tank drain valve 307. The other end of the wastewater heat exchanger 361 is connected to the drain pipe 391. Since the water tank drain valve 307 is located between the water receiving tank 39 and the other end of the wastewater heat exchanger 361, when the water tank drain valve 307 is closed, the water flowing through the wastewater heat exchanger 361 is finally discharged to the outside of the pet fur care equipment through the other end of the drain pipe 391.

[0042] like Figure 4 and Figure 9 As shown, the water system 3 also includes a bottom spray horizontal pipe 32, which extends in the left-right direction and is located below the pet passage 10. The bottom spray horizontal pipe 32 is situated below the bottom grille 101, which is located above the bottom of the water receiving trough 39. The grille gaps of the bottom grille 101 extend in the front-back direction. A bottom spray horizontal pipe spray hole is formed at the top of the bottom spray horizontal pipe 32. These spray holes are arranged in the left-right direction, corresponding to the grille gaps of the bottom grille 101. The bottom spray horizontal pipe 32 is positioned at the upper middle part of the pet passage 10 in the front-back direction. Figure 15 As shown, the bottom spray pipe 32 is connected to the outlet of the water pump 38 via the pet wash outlet valve 303. Therefore, when the water pump 38 operates and the pet wash outlet valve 303 is open, the bottom spray pipe 32 can spray water upwards onto the pet 99 located on the bottom grille 101. During this process, the water sprayed upwards from the bottom spray pipe 32 passes through the bottom grille 101, as... Figure 14 As shown, the water sprayed upward from the bottom water jet pipe 32 can clean the bottom of the pet 99's body, and then the water falls back into the water collection tank 39.

[0043] like Figure 9As shown, the pet fur care device of the present invention includes a pet drying system 4, which includes a front fan 41 and a rear fan 42. The front fan 41 is located at the front of the pet passage 10. The front fan 41 includes a front cross-flow impeller 411, an airflow electric heating tube 412, and a front fan housing 413. The front cross-flow impeller 411 and the airflow electric heating tube 412 are located inside the front fan housing 413. The upper rear part of the front fan housing 413 has a front fan inlet, and the lower rear part of the front fan housing 413 has a front fan outlet. The front fan outlet is configured to blow air generally downwards and backwards. Figure 9 As shown, the rear fan 42 is located at the rear of the pet passage 10. The rear fan 42 includes a rear cross-flow impeller 421 and a rear fan housing 423. The rear cross-flow impeller 421 is located inside the rear fan housing 423. The lower front part of the rear fan housing 423 has a rear fan inlet, and the upper front part of the rear fan housing 423 has a rear fan outlet. The rear fan outlet is positioned to blow air generally forward. Figure 10 As shown, when the cross-flow impeller 411 is running, the front fan inlet draws air from the upper part of the pet passage 10, and then the airflow passes through the airflow electric heating tube 412, during which the airflow is heated by the airflow electric heating tube 412. Afterwards, the airflow is blown roughly downwards and backwards through the front fan outlet to the lower part of the pet passage 10. When the rear cross-flow impeller 421 is running, the rear fan inlet draws air from the lower part of the pet passage 10, and then the rear fan outlet blows air to the upper part of the pet passage 10. Figure 10 The dotted arrows (indicating airflow direction) show that the front fan 41 and the rear fan 42 combine to form a circulating warm airflow. When the pet 99 is cleaned in the pet passage 10, the water pump 38 stops working, and the pet drying system 4 starts working, using the warm airflow to dry the pet 99's fur. During this process, the pet 99 receives a double-sided blowing effect. While drying the pet 99's fur, the lifting drive component 13 can drive the brush 11 to comb the pet 99's fur up and down, allowing the fur to better contact the airflow and facilitating faster evaporation of water from the fur.

[0044] like Figure 9 and Figure 11As shown, the pet fur care device of the present invention also includes a refrigerant circulation system 5, which includes a condenser 51, an evaporator 52, a throttling device, and a compressor 53. The exhaust port of the compressor 53 is connected to the condenser 51, the condenser 51 is connected to the evaporator 52 through the throttling device, and the evaporator 52 is connected to the suction port of the compressor 53. The compressor 53 is located at the rear of the pet passage 10, the condenser 51 is located inside the heating water tank 37, and the condenser 51 is located above the water heating pipe 371. The evaporator 52 is located inside the rear fan housing 423. Thus, when the refrigerant circulation system 5 is working, the heat emitted by the condenser 51 can heat the water in the heating water tank 37, and the evaporator 52 can absorb the heat in the airflow flowing through the rear fan housing 423. Since the working principle of the refrigerant circulation system 5 is prior art, it will not be described in detail here. When the pet 99 is washed and needs to be dried, the refrigerant circulation system 5 can be activated simultaneously. This causes some moisture in the airflow passing through the evaporator 52 to condense on the evaporator 52, reducing the humidity inside the pet grooming equipment and accelerating the drying process. Because the airflow heating element 412 operates simultaneously, it prevents the air temperature inside the equipment from becoming too low and making the pet 99 feel cold. The pet channel 10 can be equipped with a channel temperature sensor to detect the air temperature inside. The control circuit is electrically connected to the channel temperature sensor and the airflow heating element 412. For example, when the temperature detected by the channel temperature sensor exceeds 38°C, the control circuit stops the airflow heating element 412; when the temperature detected by the channel temperature sensor is below 36°C, the control circuit resumes operation. During the drying process, the water in the heating water tank 37 can be heated using the condenser 51, preventing the heat from the condenser 51 from being wasted and dissipated into the outside air, thus contributing to energy conservation.

[0045] like Figure 15As shown, the water system 3 also includes a cooling water pipe 35. The upper end of the cooling water pipe 35 is connected to the inlet tank 36, and a cooling water valve 306 is installed on the cooling water pipe 35. The lower end of the cooling water pipe 35 is connected to the outlet of the pet washing outlet valve 303. Before washing the pet 99, the hot water drain valve 302 is opened to drain the warm water in the heating water tank 37 into the receiving tank 39, and tap water (cold water) is added to the inlet tank 36. Then the hot water drain valve 302 is closed. Subsequently, if the water tank temperature sensor detects that the water temperature in the receiving tank 39 is too high, the control circuit can control the cooling water valve 306 and the pet washing outlet valve 303 to open (closing the washing outlet valve 304, the heat recovery outlet valve 305, and the water tank drain valve 307). Thus, the temperature in the inlet tank 36 is reduced. The cooler water flows down to the pet washing outlet valve 303 by gravity through the cooling water pipe 35. The water then flows through the pet washing outlet valve 303 and to the water pump 38. The water pump 38 is currently de-energized, so the water can flow in reverse through the pump body of the water pump 38. Since the water in the inlet tank 36 is relatively clean tap water, the water flowing in reverse through the pump body of the water pump 38 can clean the inside of the pump body. Then, the water enters the receiving tank 39 through the connecting pipe between the water inlet end of the water pump 38 and the receiving tank 39. The cooler water in the inlet tank 36 is then added to the receiving tank 39, lowering the water temperature in the receiving tank 39 to the set value. The control circuit then closes the cooling water valve 306 accordingly. Subsequently, the pet 99 enters the pet passage 10. Although the lower end of the cold water supply pipe 35 is connected to the outlet of the pet washing water valve 303, the inner diameter of the cold water supply pipe 35 is relatively large, and the cold water supply pipe 35 is set vertically. The lower end of the cold water supply pipe 35 is vertically connected to a branch pipe with a smaller inner diameter. The branch pipes are respectively connected to the spray bar 31 and the bottom spray pipe 32. Therefore, the water with a lower temperature in the water inlet tank 36 flows vertically downward through the cold water supply pipe 35 and is not easily diverted to the spray bar 31 and the bottom spray pipe 32. If a small amount of cold water is discharged through the spray bar 31 and the bottom spray pipe 32, it will fall back into the water receiving tank 39.

[0046] like Figure 9 and Figure 15As shown, the water system 3 also includes an internal cleaning nozzle assembly 300, which includes a front fan cleaning nozzle 33, a rear fan cleaning nozzle 34, a front upper nozzle 3101, and a rear upper nozzle 3102. The front upper nozzle 3101 is located in front of the upper end of the upright frame 14 at the front position, and the rear upper nozzle 3102 is located behind the upper end of the upright frame 14 at the rear position. The front upper nozzle 3101 is set to spray water generally towards the rear and downward, and the rear upper nozzle 3102 is set to spray water generally towards the front. With the water spraying mechanism positioned slightly downwards, the front upper spray pipe 3101 and the rear upper spray pipe 3102 spray water roughly towards the upper end of the pet passage 10. When some of the water sprayed from the front upper spray pipe 3101 and the rear upper spray pipe 3102 collides with the side fence 102 and the upright frame 14, it will splash and disperse, and the water will eventually fall into the water receiving tank 39. During this process, the water can carry away some of the pet hair attached to the upright frame 14 and the side fence 102, thereby cleaning the inside of the pet fur care equipment. The front fan cleaning nozzle 33 is located at the top inner part of the front fan housing 413. The front fan cleaning nozzle 33 sprays water towards the forward-flowing impeller 411, meaning it sprays water roughly downwards. Therefore, the water sprayed from the front fan cleaning nozzle 33 can wash away the hair (fallen from Pet 99) on the forward-flowing impeller 411. The water carrying the hair is then discharged from the front fan outlet, and the water falls into the water collection tank 39. The rear fan cleaning nozzle 34 is located inside the rear fan housing 423. The rear fan cleaning nozzle 34 sprays water roughly upwards. The rear fan cleaning nozzle 34 is located on the lower rear side of the rear-flowing impeller 421, so the water sprayed from the rear fan cleaning nozzle 34 can wash away the hair on the rear-flowing impeller 421. Figure 15 As shown, the outlet of the water pump 38 is connected to the internal cleaning nozzle assembly 300 via the cleaning outlet valve 304. When the inside of the pet fur care equipment needs to be cleaned, the cleaning outlet valve 304 is opened, while the hot water drain valve 302, the pet washing outlet valve 303, and the heat recovery outlet valve 305 are closed, causing the water pump 38 to operate. The water pump 38 draws water from the water tank 39 and sends it to the internal cleaning nozzle assembly 300, causing the front fan cleaning nozzle 33, the rear fan cleaning nozzle 34, the front upper nozzle 3101, and the rear upper nozzle 3102 to spray water simultaneously. The water then flows down into the water tank 39, thus forming a water circulation. When the internal cleaning nozzle assembly 300 is finished using, as... Figure 15 As shown, open the drain valve 307 of the water tank to allow the wastewater in the water tank 39 to be discharged directly to the outside of the pet fur care area.

[0047] Furthermore, such as Figure 1 and Figure 12As shown, the pet fur care device of the present invention also includes a housing assembly 6, a washing mechanism 1 and a pet channel 10 disposed inside the housing assembly 6. The housing assembly 6 is provided with a right channel door 61, a left channel door 62, a rear cover plate 64 and a front cover shell 65. The rear cover plate 64 is located at the rear end of the pet fur care device, the front cover shell 65 is located at the front of the pet fur care device, the right channel door 61 is correspondingly disposed at the right end of the pet channel 10, and the left channel door 62 is correspondingly disposed at the left end of the pet channel 10. Before pet 99 enters pet passage 10, the right door 61 and left door 62 of the passage can be opened, allowing pet 99 to enter the pet fur care equipment from either the left or right side. Afterwards, the right door 61 and left door 62 can be closed. This prevents water from splashing out from both ends of pet passage 10 during the washing process using the brushing mechanism 1 and the bottom water spray pipe 32. When drying pet 99, the right door 61 and left door 62 can remain closed, preventing heat loss from pet passage 10 to the outside of the pet fur care equipment, especially in winter. Both the right door 61 and left door 62 are horizontally swinging doors. Once pet 99 is dried, opening the right door 61 and left door 62 allows pet 99 to leave pet passage 10 on its own.

[0048] Furthermore, such as Figure 1 As shown, the outer casing assembly 6 is equipped with a channel top door 63, which is located on the upper side of the pet channel 10. Some pets 99 may be unfamiliar with pet grooming equipment, so when washing the pet 99, the channel top door 63 can be opened, opening the top of the pet channel 10. This effectively increases the vertical space of the pet channel 10, reducing the pet 99's fear in a confined space. The pet owner can also interact with the pet 99 inside the pet channel 10 visually and auditorily through the top of the pet channel 10, which helps to soothe the pet 99. When drying the pet 99, the channel top door 63 can be closed. The channel top door 63 can be slid forward and backward; sliding forward closes the channel top door, and sliding backward opens it. Figure 8 As shown, the outer casing assembly 6 may be equipped with a channel top door opening and closing motor 66, which is installed on the top of the water inlet tank 36. The channel top door opening and closing motor 66 is driven by an opening and closing screw rod, which extends in the front-back direction. A screw block is screwed onto the opening and closing screw rod, and the screw block is installed at the rear end of the channel top door 63. Thus, the channel top door opening and closing motor 66 can drive the opening and closing screw rod to rotate, and the opening and closing screw rod can drive the channel top door 63 to move back and forth.
