Description

Technical Field

[0001] This invention specifically relates to a multi-directional drying device for pet cleaning. Background Technology

[0002] With the development of the pet breeding industry, the demand for pet drying after cleaning is increasing. Existing pet drying devices generally have the following problems: most devices only exhaust air from one side, such as the rear or top, resulting in drying dead spots on the sides and abdomen of the pet's body. It is necessary to manually turn the pet to complete the drying, which is cumbersome and can easily cause stress to the pet; some multi-directional drying devices require multiple independent drive components to control the air outlet mechanism in different directions, which not only increases the size of the equipment and manufacturing cost, but is also prone to air path switching failure due to the coordination error of multiple drives.

[0003] To address the aforementioned shortcomings, there is an urgent need for a pet drying device that can achieve precise airflow from multiple directions and single-drive control of airflow path switching, in order to overcome the deficiencies of existing technologies. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a multi-directional drying device for pet cleaning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multi-directional drying device for pet cleaning includes a housing with drying chambers and doors for opening and closing the drying chambers. It also includes an air duct with an air inlet and several air outlets. The air outlets include a first air chamber located behind the drying chamber, second air chambers located on either side of the drying chamber, and a third air chamber located above the drying chamber. The first, second, and third air chambers are connected to the drying chamber via several first air outlets. A partition is provided within the first air chamber to divide it into a fourth and a fifth air chamber. The fourth air chamber is connected to the drying chamber via a first air outlet. The air vents are connected to the drying chamber. The fourth air chamber has third air outlets on both sides, each connected to the second air chamber. The air inlet chamber is connected to the fifth air chamber. A movable plate, movably positioned within the fourth air chamber, has a recessed cavity on its side near the partition, with a second air outlet extending through it. The partition has a first protrusion and a second protrusion on its side facing the cavity. The first protrusion has a fourth air outlet extending through it. The cavity can cover the first protrusion and seal the opening of the fourth air outlet as the movable plate moves. The second protrusion can correspondingly engage with the second air outlet to seal it. The second air outlet is blocked. A fifth air outlet is formed through the upper end of the cavity, and a sixth air outlet is formed through the lower side of the third air cavity. The fifth air outlet can connect with the sixth air outlet as the movable plate moves. Baffles that can block the third air outlet are provided on both sides of the movable plate. A seventh air outlet is formed through the baffles and can connect with the third air outlet as the movable plate moves. The movable plate has three stroke positions: stroke A, stroke B, and stroke C. When the movable plate is in stroke A, the fourth air outlet connects with the second air outlet, and the third air outlet and the sixth air outlet are separated. The hot air is blown out from the first air chamber located at the rear of the drying chamber, without being blocked by the sidewall and the upper side of the movable plate. When the movable plate is in stroke B, the third air outlet and the seventh air outlet are connected, and at this time the second air outlet and the sixth air outlet are blocked by the second protrusion and the upper side of the movable plate, respectively. The hot air is blown out from the second air chamber located on the left and right sides of the drying chamber. When the movable plate is in stroke C, the fifth air outlet and the sixth air outlet are connected, and at this time the fourth air outlet is blocked by the side wall of the cavity. The hot air is blown out from the third air chamber located on the upper side of the drying chamber. A driving component is set on the box body to drive the movable plate to move. A hot air device is set in the air inlet cavity.

[0006] In one embodiment, the driving component includes a first guide shaft, a screw, and a motor. The first guide shaft and the screw are respectively disposed on the housing and are both transverse and relatively parallel, spanning between the air inlet cavity and the first air cavity. The screw and the housing are rotatably connected by a bearing. The motor is disposed on the housing and its driving end is connected to the screw to drive the screw to rotate. The movable plate is movably sleeved on the first guide shaft through a linear bearing, and the movable plate is threadedly connected to the screw.

[0007] In one embodiment, it further includes a first baffle and a first transmission component. A first return air hole is connected between the second air cavity and the air inlet cavity. The first baffle is movably disposed in the air inlet cavity to block the first return air hole. The baffle extends movably through the partition into the air inlet cavity. The first transmission component is connected between the baffle and the first baffle to drive the first baffle to move left and right as the baffle moves back and forth.

[0008] In one embodiment, the first transmission component includes V-shaped guide grooves symmetrically arranged on the upper and lower sides of the first baffle. An opening is formed through the baffle, and the first baffle is located within the opening. Fourth guide shafts are symmetrically arranged on the upper and lower sides of the opening, and the fourth guide shafts are movably disposed within the V-shaped guide grooves. When the movable plate is at stroke A, the fourth guide shaft is located at the front end of the V-shaped guide groove, and the first baffle is in a connected state with the first return air hole unobstructed. When the movable plate is at stroke B, the fourth guide shaft is located in the middle of the V-shaped guide groove, and the first baffle is in a connected state with the first return air hole blocked. When the movable plate is at stroke C, the fourth guide shaft is located at the rear end of the V-shaped guide groove, and the first baffle is in a connected state with the first return air hole unobstructed.

[0009] In one embodiment, a second guide shaft is provided on the left and right sides of the air inlet cavity, and the first baffle is movably sleeved on the second guide shaft through a linear bearing, so that the first baffle moves laterally relative to the housing along the axial direction of the second guide shaft.

[0010] In one embodiment, a second baffle and a second transmission component are further included. A second return air hole is connected between the third air cavity and the air inlet cavity. The second baffle is movably disposed in the air inlet cavity. A connecting plate protrudes outward from the upper side of the movable plate. The connecting plate extends movably through the partition into the air inlet cavity. The second transmission component is connected between the second baffle and the connecting plate.

[0011] In one embodiment, the second transmission component includes a V-shaped groove recessed into the upper side of the connecting plate, and the lower end of the second baffle is an arc surface, which movably abuts against the V-shaped groove. When the movable plate is in stroke A, the arc surface of the second baffle is located on the upper rear end of the V-shaped groove, and the second baffle is in a state of blocking and sealing the second return air hole. When the movable plate is in stroke B, the arc surface of the second baffle is located in the concave middle of the V-shaped groove, and the second baffle is in a state of unblocking the second return air hole. When the movable plate is in stroke C, the arc surface of the second baffle is located on the upper front end of the V-shaped groove, and the second baffle is in a state of blocking and sealing the second return air hole.

[0012] In one embodiment, a third guide shaft is provided at an interval on the upper side of the air inlet cavity, and the second baffle is movably sleeved on the third guide shaft through a linear bearing, so that the second baffle can move up and down relative to the housing along the axial direction of the third guide shaft.

[0013] In one embodiment, the hot air device includes a fan and an electric heating element disposed within the air inlet chamber.

[0014] In one embodiment, a plurality of air inlet holes are respectively provided through both sides of the air inlet cavity.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention uses an air duct design to form three air outlet directions: a first air chamber on the rear side, second air chambers on both sides, and a third air chamber on the upper side. Combined with the three travel positions of the movable plate, it can target and dry the fur on the back, sides, and top of the pet, completely eliminating drying dead spots and achieving uniform drying of the entire pet without manual intervention. The movable plate can be moved by a single set of drive components, including a motor, screw, and guide shaft, enabling precise switching between three air paths. Compared to multi-drive solutions, this reduces drive components by more than 60%, lowering equipment size and manufacturing costs. It also avoids multi-drive coordination errors and improves the reliability of air path switching. Through the coordinated design of the first baffle, the second baffle, and the movable plate, the return air vent of the idle air chamber is automatically opened and the return air vent of the working air chamber is closed under different stroke conditions. That is, the working air chamber is only responsible for outputting hot air to the drying chamber, and the idle air chamber is only responsible for guiding the return air from the drying chamber back to the air inlet chamber. This ensures that the hot air circulates in a closed loop between the working air chamber and the drying chamber, the idle air chamber and the air inlet chamber, and the working air chamber. This completely avoids the direct loss of hot air from the drying chamber, increases the heat utilization rate by more than 30%, and significantly reduces energy consumption.

Detailed Implementation

[0017] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0018] like Figures 1 to 7The multi-directional drying device for pet cleaning shown includes a housing 1, which has a drying chamber 2 and a door panel 3 for opening and closing the drying chamber 2. It also includes an air duct with an air inlet 4 and several air outlets. The air outlets include a first air chamber 5 located behind the drying chamber 2, second air chambers 6 located on both sides of the drying chamber 2, and a third air chamber 7 located above the drying chamber 2. The first air chamber 5, second air chamber 6, and third air chamber 7 are connected to the drying chamber 2 through several first air outlets 8. A partition 9 is provided inside the first air chamber 5, dividing it into a fourth air chamber 10 and a fifth air chamber 11. The fourth air chamber 10 is connected to the drying chamber 2 through the first air outlets 8. The fourth air chamber 10 is connected to the second air chamber 6 by having third air outlets 12 on both sides. The air inlet chamber 4 is connected to the fifth air chamber 11. A movable plate 13 is movably disposed in the fourth air chamber 10. A cavity 14 is recessed on the plate 13 near the partition 9, and a second air outlet 15 is provided through the cavity 14. The partition 9 has a first protrusion 16 and a second protrusion 17 on the side facing the cavity 14. A fourth air outlet 18 is provided through the first protrusion 16. The cavity 14 can cover the first protrusion 16 and block the opening of the fourth air outlet 18 as the movable plate 13 moves. The second protrusion 17 can be correspondingly inserted into the second air outlet 15 to block the second air outlet 18. 5. A fifth air outlet 19 is provided through the upper end of the cavity 14, and a sixth air outlet 20 is provided through the lower side of the third air cavity 7. The fifth air outlet 19 can communicate with the sixth air outlet 20 as the movable plate 13 moves. Baffles 21 that can block the third air outlet 12 are provided on both sides of the movable plate 13. A seventh air outlet 22 is provided through the baffles 21, and the seventh air outlet 22 can communicate with the third air outlet 12 as the movable plate 13 moves. The movable plate 13 has three stroke positions: stroke A, stroke B, and stroke C. When the movable plate 13 is in stroke A, the fourth air outlet 18 is connected to the second air outlet 15, and at this time, the third air outlet 12 and the sixth air outlet 20 are blocked. Side 21 is blocked from the upper side of movable plate 13, and hot air is blown out from the first air chamber 5 located on the rear side of drying chamber 2; when movable plate 13 is in stroke B, the third air outlet 12 and the seventh air outlet 22 are connected, and at this time the second air outlet 15 and the sixth air outlet 20 are blocked by the second protrusion 17 and the upper side of movable plate 13 respectively, and hot air is blown out from the second air chamber 6 located on the left and right sides of drying chamber 2; when movable plate 13 is in stroke C, the fifth air outlet 19 and the sixth air outlet 20 are connected, and at this time the fourth air outlet 18 is blocked by the side wall of cavity 14, and hot air is blown out from the third air chamber 7 located on the upper side of drying chamber 2; driving component 23 is set on the box 1 to drive movable plate 13 to move; hot air device 24 is set in air inlet 4.

[0019] Specifically, the driving component 23 drives the movable plate 13 to move back and forth, switching between three stroke positions to achieve the hot air output switching of "rear side → both sides → upper side". Combined with the hot air generated by the hot air device 24, the pet in the drying chamber 2 is dried in multiple directions.

[0020] When the movable plate is in stroke A, the first air cavity 5 is the working air cavity; Path: Hot air in air inlet 4 → flows directly into fifth air chamber 11. Because the fifth air chamber is directly connected to the air inlet and there is no obstruction, the hot air in the fifth air chamber → flows through the fourth air outlet 18 of the first protrusion 16 → flows into the second air outlet 15 of the movable plate 13 → enters the fourth air chamber 10. The function of partition 9 is to divide the first air cavity 5 into the fifth air cavity 11, the hot air transfer center and the fourth air cavity 10, and to temporarily store the hot air, so as to prevent the hot air from spreading disorderly in the first air cavity. Path: Hot air in the fourth air chamber 10 → blows directly to the rear side of the drying chamber 2 through several first air outlets 8 on its side wall facing the drying chamber 2; When the movable plate is in stroke B, the second air cavity 6 is the working air cavity; Path: Hot air in air inlet 4 → fifth air chamber 11 → fourth air chamber 10. Because the second air outlet 15, the fifth air outlet 19 and the sixth air outlet 20 are blocked, the hot air cannot flow to the first air chamber and can only diffuse in the fourth air chamber → hot air in the fourth air chamber → seventh air outlet 22 of the baffle 21 → third air outlet 12 of the second air chamber 6 → fills the second air chamber 6 and blows towards the drying chamber 2; When the movable plate is in stroke C, the third air chamber 7 is the working air chamber; Path: Hot air in air inlet 4 → fifth air chamber 11 → fourth air chamber 10. Because the third air outlet 12 and the fourth air outlet 18 are blocked, the hot air cannot flow to the second air chamber and the first air chamber, and can only gather in the cavity 14 of the movable plate 13 → hot air in the cavity → fifth air outlet 19 on the upper side of the movable plate 13 → sixth air outlet 20 of the third air chamber 7 → fills the third air chamber 7 and blows towards the drying chamber 2; Furthermore, the driving component 23 includes a first guide shaft 25, a screw 26, and a motor 27. The first guide shaft 25 and the screw 26 are respectively disposed on the housing 1 and are both transverse and relatively parallel, spanning between the air inlet cavity 4 and the first air cavity 5. The screw 26 is rotatably connected to the housing 1 through a bearing. The motor 27 is disposed on the housing 1 and its driving end is connected to the screw 26 to drive the screw 26 to rotate. The movable plate 13 is movably sleeved on the first guide shaft 25 through a linear bearing, and the movable plate 13 is threadedly connected to the screw 26.

[0021] Specifically, after receiving the control signal, the motor 27 rotates, driving the screw 26 to rotate synchronously through the coupling. Because the movable plate 13 is sleeved on the first guide shaft 25 through a linear bearing, it cannot rotate with the screw 26, but can only move in the axial direction of the first guide shaft 25. That is, when the motor 27 rotates forward, the screw 26 drives the movable plate 13 to move forward until the cavity 14 separates from the first protrusion 16 at stroke A. When the motor 27 rotates in reverse, the movable plate 13 moves backward. The encoder provides real-time feedback on the motor rotation angle. When the rotation angle reaches the preset value 1, corresponding to the movable plate moving backward by 10cm, the motor pauses at stroke B. When the rotation angle reaches the preset value 2, corresponding to the movable plate moving backward by 20cm, the motor pauses again at stroke C, achieving precise switching between the three strokes and avoiding manual adjustment errors.

[0022] Furthermore, it also includes a first baffle 28 and a first transmission component 29. A first return air hole 30 is connected between the second air cavity 6 and the air inlet cavity 4. The first baffle 28 is movably disposed in the air inlet cavity 4 to block the first return air hole 30. The baffle 21 extends movably through the partition 9 into the air inlet cavity 4. The first transmission component 29 is connected between the baffle 21 and the first baffle 28 to drive the first baffle 28 to move left and right as the baffle 21 moves back and forth.

[0023] Furthermore, the first transmission component 29 includes V-shaped guide grooves 31 symmetrically arranged on the upper and lower sides of the first baffle 28. The baffle 21 has a through hole 32, and the first baffle 28 is located in the hole 32. Fourth guide shafts 99 are symmetrically arranged on the upper and lower sides of the hole 32, and the fourth guide shafts 99 are movably arranged in the V-shaped guide grooves 31. When the movable plate 13 is in stroke A, the fourth guide shaft 99 is located at the front end of the V-shaped guide groove 31, and the first baffle 28 is in a connected state with the first return air hole 30 unobstructed. When the movable plate 13 is in stroke B, the fourth guide shaft 99 is located in the middle of the V-shaped guide groove 31, and the first baffle 28 is in a connected state with the first return air hole 30 blocked. When the movable plate 13 is in stroke C, the fourth guide shaft 99 is located at the rear end of the V-shaped guide groove 31, and the first baffle 28 is in a connected state with the first return air hole 30 unobstructed.

[0024] Specifically, the movable plate 13 moves back and forth, which drives the extension section of the retaining edge 21 to move back and forth. The transmission guide shaft in the opening 32 slides along the V-shaped guide groove 31, which pushes the first baffle 28 to move left and right, thus realizing the mechanical linkage of "movable plate displacement → baffle opening and closing" without additional drive. It also enables return air control for idle air cavities: Stroke A: The movable plate moves forward: The transmission guide shaft is located at the front end of the V-shaped guide groove 31 → The guide shaft pushes the front end of the V-shaped groove, causing the first baffle 28 to move to the left → The first return air hole 30 is fully exposed and opened → The return air of the second air cavity 6 can flow into the air inlet cavity 4; Stroke B: The movable plate moves to the middle: The transmission guide shaft slides to the middle of the V-shaped guide groove 31 → The guide shaft pushes the V-shaped groove inflection point, causing the first baffle 28 to move to the right to the extreme position → The first return air hole 30 is completely covered and closed by the baffle → There is no return air loss in the working air cavity of the second air cavity 6; Stroke C: The movable plate moves backward: The transmission guide shaft slides to the rear end of the V-shaped guide groove 31 → The guide shaft pulls the rear end of the V-shaped groove, causing the first baffle 28 to move to the left → The first return air hole 30 opens again → The second air chamber 6 returns air.

[0025] Furthermore, the air inlet cavity 4 is provided with second guide shafts 33 on both the left and right sides. The first baffle 28 is movably sleeved on the second guide shafts 33 via linear bearings, so that the first baffle 28 can move laterally relative to the housing 1 along the axial direction of the second guide shafts 33. Specifically, when the first baffle 28 moves left and right under the drive of the first transmission component 29, it slides along the second guide shafts 33 via linear bearings. The guide shafts restrict the baffle to move only in the left and right directions, preventing the baffle from tilting, jamming, or shifting due to uneven force, ensuring that the baffle is always aligned with the first return air hole 30, achieving "complete sealing" or "complete opening".

[0026] Furthermore, it also includes a second baffle 34 and a second transmission component 35. A second return air hole 36 is connected between the third air cavity 7 and the air inlet cavity 4. The second baffle 34 is movably disposed in the air inlet cavity 4. A connecting plate 37 protrudes outward from the upper side of the movable plate 13. The connecting plate 37 extends movably through the partition 9 into the air inlet cavity 4. The second transmission component 35 is connected between the second baffle 34 and the connecting plate 37. Furthermore, the second transmission component 35 includes a V-shaped groove 38 recessed on the upper side of the connecting plate 37, and the lower end of the second baffle 34 is an arc surface, which movably abuts against the V-shaped groove 38. When the movable plate 13 is in stroke A, the arc surface of the second baffle 34 is located on the upper rear end of the V-shaped groove 38, and the second baffle 34 is in a state of blocking and sealing the second return air hole 36. When the movable plate 13 is in stroke B, the arc surface of the second baffle 34 is located in the concave middle of the V-shaped groove 38, and the second baffle 34 is in a state of unblocking the second return air hole 36. When the movable plate 13 is in stroke C, the arc surface of the second baffle 34 is located on the upper front end of the V-shaped groove 38, and the second baffle 34 is in a state of blocking and sealing the second return air hole 36. Specifically, the movable plate 13 moves back and forth, which drives the connecting plate 37 to move back and forth, and the V-shaped groove 38 slides back and forth synchronously. The inner wall of the groove generates an upward / downward thrust on the arc surface of the second baffle 34, and the second baffle 34 moves up and down, realizing the mechanical linkage of "movable plate displacement → opening and closing of the second return air hole". It also enables return air control for idle air cavities: Stroke A: Moving plate forward: Connecting plate 37 moves forward → V-shaped groove 38 front end lifts up → Arc surface slides along V-shaped groove slope → Second baffle 34 moves up → Second return air hole 36 closes → Third air chamber 7 has no return air loss; Stroke B: Moving the movable plate in the middle: Connecting plate 37 moves in the middle → V-shaped groove 38 turns upward → Arc surface is located at the turning point in the middle of the V-shaped groove → Second baffle 34 moves downward → Second return air hole 36 opens to return air to the air inlet cavity; Stroke C: Moving plate moves backward: Connecting plate 37 moves backward → V-shaped groove 38 rear end lifts up → Arc surface slides along V-shaped groove slope → Second baffle 34 moves up → Second return air hole 36 closes → Third air chamber 7 working air chamber has no return air loss.

[0027] Furthermore, a third guide shaft 39 is provided at an interval on the upper side of the air inlet cavity 4. The second baffle 34 is movably sleeved on the third guide shaft 39 via a linear bearing, so that the second baffle 34 can move up and down relative to the housing 1 along the axial direction of the third guide shaft 39. Specifically, when the second baffle 34 moves up and down under the drive of the second transmission component 35, it slides along the third guide shaft 39 via the linear bearing. The guide shaft restricts the baffle to move only in the up and down direction, avoiding the baffle from shifting or tilting back and forth due to uneven force on the arc surface, ensuring that the baffle is always aligned with the second return air hole 36, achieving precise sealing / opening.

[0028] Furthermore, the hot air device 24 includes a fan 40 and an electric heating tube 41 disposed in the air inlet chamber 4.

[0029] Specifically, after the device is started, the fan 40 and the heating element 41 are powered on simultaneously. The fan 40 draws in cold air from the outside through the air inlet holes 42 on both sides of the air inlet chamber 4, pressurizes the cold air, and blows it toward the heating element 41. When the cold air flows through the heating element 41, it absorbs the heat generated by the heating element, and the temperature rises to 40-60℃, forming hot air. Under the action of the air pressure of the fan 40, the hot air flows to the right and enters the fifth air chamber 11. Then, according to the stroke of the movable plate 13, it enters the corresponding first / second / third air chamber through different channels, and finally blows it toward the pet in the drying chamber 2 from the first air outlet 8. The temperature sensor provides real-time feedback on the hot air temperature, and the temperature controller automatically adjusts the on / off state of the heating element 41 according to the preset temperature range of 40-60℃ to ensure that the hot air temperature is always within a safe range, ensuring that the drying efficiency temperature is ≥40℃, while avoiding damage to the pet's fur due to high temperature (≤60℃).

[0030] Furthermore, several air inlet holes 42 are respectively opened through both sides of the air inlet cavity 4. Specifically, a layer of dustproof mesh made of nylon with a mesh size of 100 is attached to the air inlet holes 42 on the outer side of the air inlet cavity 4. The dustproof mesh is fixed by buckles and can be disassembled and cleaned periodically to prevent external dust and hair from entering the air inlet cavity 4 and clogging the fan 40 or the electric heating tube 41. When the fan 40 is working, a negative pressure is formed in the air inlet cavity 4. Under the action of atmospheric pressure, outside air passes through the dustproof mesh and enters the air inlet holes 42 to replenish the air in the air inlet cavity 4.
