As a further improvement of the present technique, the distance between the two sliders is closest when the support mechanism is not depressed.

The space between the L-shaped limiting plate and the cover is named as a locking space.

According to the invention, the cover swings around the hinge point by pulling the handle; the effect that pendulum plate and L type limiting plate matched with is: when the swinging plate swings to the locking space, the L-shaped limiting plate is limited, and the cover cannot be opened; when the swinging plate does not swing to the upper locking space, the L-shaped limiting plate is not limited, and then the cover can be opened. The design that the two ends of the swinging plate are symmetrical relative to the first shaft is that after one end of the swinging plate swings to the locked space, the swinging plate can still make the swinging plate separate from the locked space by swinging the other end.

For the unlocking mechanism: the elastic coefficient of the first spring is lower, so that when a lighter pet is placed on the pedal, the first spring is also compressed; the four telescopic rods are used for facilitating the pedals to stably move in the drying cavity; the first spring has the function of enabling the pedal to move and reset. One end of the rotating shaft is installed on the connecting block, the other end of the rotating shaft penetrates out of the sliding square hole and is provided with the swinging plate, and the swinging plate can rotate around the axis of the rotating shaft under the stirring of a user. The footboard is with first spacing strip and the spacing strip matched with effect of second is: when the first push plate and the second push plate are not pushed away, the first limiting strip and the second limiting strip of the pedal are limited, and pets on the pedal cannot enable the pedal to move towards the base; when the first push plate and the second push plate are pushed away, the first limiting strip and the second limiting strip are limited and do not limit the pedal any more, so that a pet on the pedal can enable the pedal to move towards the base, and the first spring is compressed.

The first push plate is uniformly provided with a plurality of air outlet holes, and the function of the first push plate is as follows: after the ventilation mechanism sends the hot air into the drying cavity, the hot air can be discharged from the air outlet hole, so that a circulating system is formed.

The first baffle plate is used for preventing the first push plate from being separated from the shell of the dryer in the moving process; the second baffle plate is used for preventing the second push plate from being separated from the shell of the dryer in the moving process.

For the ventilation mechanism: the air pump can suck the outside air through the first air duct, and then the outside air is sent into the electric heater through the second air duct; after the electric heater heats the outside air, the heated air flows into the square expansion port from the L-shaped air duct flow, the electromagnetic valve and the sixth air duct; the square expansion port is arranged in the air inlet square hole, so that the square expansion port is fixed, and the square expansion port is used for quickly diffusing the dense hot air flowing in from the sixth air duct into the drying cavity.

Each ventilation shell is internally provided with an air accumulation cavity, a plurality of air outlet pipes are uniformly arranged on the lower plate surface of the air accumulation cavity along the length direction of the ventilation shell, the air outlet pipe in each ventilation shell penetrates through a corresponding row of air inlet holes, two fourth air guide pipes are symmetrically arranged on the L-shaped air guide pipe, one ends of the two fourth air guide pipes, which are not connected with the second air guide pipes, are respectively connected with the two ventilation shells, and each fourth air guide pipe is respectively communicated with the L-shaped air guide pipe and the air accumulation cavity in the corresponding ventilation shell, so that a small part of hot air in the L-shaped air guide pipes can flow into the air accumulation cavity of the ventilation shell from the fourth air guide pipes, and then the hot air in the air accumulation cavity flows into the drying cavity through the plurality of air outlet pipes, and the design ensures that the pet in the drying cavity can be dried by hot air from the top plate in more directions; because only a small part of hot air flows out of the L-shaped air duct and is divided by the air outlet pipes, the temperature of the hot air exhausted by the air outlet pipes is lower than that of the hot air exhausted by the square expansion openings.

The opening and closing amount of the electromagnetic valve is controlled by the second L-shaped rod, the electromagnetic valve controls the air displacement of the fifth air guide pipe, and the electromagnetic valve controls the air displacement of the fifth air guide pipe to be zero when the second L-shaped rod does not move in the direction away from the side plate when the dryer is not overheated; when the dryer is overheated, the second L-shaped rod moves towards the direction far away from the side plate, and then the second L-shaped rod controls the electromagnetic valve, so that part of the overheated air flowing into the electromagnetic valve from the L-shaped air guide pipe is discharged into the atmosphere through the fifth air guide pipe, and the amount of movement of the second L-shaped rod towards the direction far away from the side plate is larger, and the overheated air discharged into the atmosphere through the fifth air guide pipe is also more.

The first guide rail is arranged on the top plate, and the third rod slides in the first guide rail, so that the motion track of the third rod is fixed relatively. The first gear is meshed with the first rack and the second rack respectively, when the first push plate drives the first L-shaped rod to move towards the direction away from the square expansion port, the first rack moves towards the direction away from the square expansion port along with the first L-shaped rod, the first rack drives the first gear to rotate, the second rack moves towards the first guide rail direction due to the rotation of the first gear, and the third rod moves towards the electromagnetic valve direction. Under the pushing of the third rod, the second L-shaped rod moves away from the side plate.

The bevel gear on the second gear meshes with the bevel gear on the third gear mutually, and the third gear meshes with the third rack mutually, so when the second push pedal drives the second pole and removes to the direction of keeping away from the shell that ventilates, the third rack is followed the second pole and is removed to the direction of keeping away from the shell that ventilates, and then the third rack drives the third gear rotation, and the third gear drives the second gear rotation.

The second gear and the second rack are matched to act as follows: when the first push plate does not move and only the second push plate moves, the second gear and the second rack cannot be meshed; when the first push plate moves, the second rack moves towards the first guide rail direction under the rotation driving of the first gear, and the second rack can only be meshed with the second gear when moving to a certain position.

The length of the second rack is equal to the distance between the axle center of the first gear and the axle center of the second gear, when the first gear drives the second rack to move for a certain position, the second rack is about to be disengaged from the first gear to prepare for generating a meshing relation with the second gear, so that when the second gear drives the second rack to move, the second rack cannot drive the first gear to rotate.

In order to prevent the ventilation mechanism from being exposed and prevent the adverse effect of long-time dust accumulation on the dryer, the pet dryer of the invention needs to be provided with a dustproof shell.

When the first push plate and the second push plate need to be pushed, the friction force is higher, so that the first push plate and the second push plate need to be pushed only by higher pushing force; that is, a slight push by the pet does not move the first and second push plates when the pet is not in a very restless condition.

For the unlocking mechanism: the elastic coefficient of the first spring is lower, so that when a lighter pet is placed on the pedal, the first spring is also compressed; the three supporting mechanisms are used for facilitating the pedal to stably move in the drying cavity; the first spring has the function of enabling the pedal to move and reset. One end of the rotating shaft is installed on the connecting block, the other end of the rotating shaft penetrates out of the sliding square hole and is provided with the swinging plate, and the swinging plate can rotate around the axis of the rotating shaft under the stirring of a user. The footboard is with first spacing strip and the spacing strip matched with effect of second is: when the first push plate and the second push plate are not pushed away, the first limiting strip and the second limiting strip of the pedal are limited, and pets on the pedal cannot enable the pedal to move towards the base; when the first push plate and the second push plate are pushed away, the first limiting strip and the second limiting strip are limited and do not limit the pedal any more, so that a pet on the pedal can enable the pedal to move towards the base, and the first spring is compressed.

For the support mechanism: when the pedal moves towards the direction of the base, the two supporting strips are pressed downwards; in the process that the two supports are pressed down, one ends of the two support bars, which are connected with the sliding blocks, move in the direction away from each other, and then the two sliding blocks are driven to move in the direction away from each other; in the process that two support bars are pushed down, the intersection points of the two support bars can move down along with the intersection points, the pin can move down along with the intersection points, and then the telescopic rod is compressed.

When the pet dryer does not work, one end of the swinging plate is positioned in the locking space, and the L-shaped limiting plate and the cover are limited by the swinging plate; the pedal is contacted with the first push plate and the second push plate and is limited by the first limiting strip and the second limiting strip; the first spring is uncompressed.

When the pet needs to be dried, a user stirs one end of the swinging plate, which does not enter the locked space, so that one end of the swinging plate, which is positioned in the locked space, is separated, and the user can open the cover by using the handle. Then, the user puts the pet into the drying cavity, and the pet is placed on the pedal; the user covers the lid again, and the pendulum board is stirred to the rethread for the one end of pendulum board enters into the space of locking again and is spacing with the lid, prevents that the pet from running out from the drying-machine. Subsequently, the dryer starts drying the pet: the external air is fed into the electric heater through the first air duct and the second air duct under the action of the air pump, the electric heater heats the external air, the heated air flows into the square expansion port from the L-shaped air duct flow, the electromagnetic valve and the sixth air duct, and then the intensive hot air is rapidly diffused into the drying cavity through the square expansion port; in addition, a small part of hot air in the L-shaped air guide pipe can flow into the air accumulation cavity of the ventilation shell from the fourth air guide pipe, then the hot air in the air accumulation cavity flows into the drying cavity through the air outlet pipes, and due to the design, the pet in the drying cavity can be heated by the hot air from the top plate, so that the pet can be dried by the hot air in more directions. After the pet is dried, the user stirs the swing plate again, so that one end of the swing plate, which is positioned in the locking space, is separated, the user can open the cover by using the handle, and the pet can come out of the dryer.

When the overheating condition or the failure of the temperature regulator occurs in the drying process of the pet dryer, the air exhausted by the ventilation mechanism is overheated, the pet feels severe physical discomfort at the moment, the pet becomes very restless, and even the pet can move around on the pedal. Because the temperature of the overheated air discharged from the square expansion port is higher than that of the hot air discharged from the air outlet pipe, and the square expansion port is larger than the air quantity discharged from the air outlet pipe, the pet can avoid the overheated air coming from the direction of the square expansion port; when the pet forcibly retreats towards the first push plate to avoid the overheated air from the direction of the square expansion opening, the first push plate is pushed and moves towards the direction far away from the square expansion opening; the first push plate drives the first L-shaped rod to move towards the direction away from the square expansion opening, the first rack moves towards the direction away from the square expansion opening along with the first L-shaped rod, the first rack drives the first gear to rotate, and the rotation of the first gear enables the second rack to move towards the first guide rail; when the first gear drives the second rack to move a certain position, the second rack is about to be disengaged from the first gear and is meshed with the second gear; the second rack drives the third rod to move towards the direction of the electromagnetic valve; under the pushing of the third rod, the second L-shaped rod moves towards the direction far away from the side plate, and then the second L-shaped rod controls the electromagnetic valve, so that part of the superheated air flowing into the electromagnetic valve from the L-shaped air guide pipe is discharged into the atmosphere through the fifth air guide pipe; at the moment, because less superheated air flows out from the fifth air duct, the temperature of the superheated air entering the drying cavity is still higher, and the pet is still in a very restless state. When the pet feels that the pet retreats in the direction far away from the square expansion port, the pet still cannot avoid the overheated air, the pet can avoid in the direction of one side of the air port of the square expansion port, and the pet can forcibly avoid the overheated air from the direction of the square expansion port in the direction of the second push plate; when the pet forcibly retreats towards the second push plate to avoid the overheated air from the direction of the square expansion port, the second push plate is pushed and moves towards the direction far away from the ventilation shell; the second push plate drives the second rod to move towards the direction far away from the ventilation shell, the third rack moves towards the direction far away from the ventilation shell along with the second rod, the third rack drives the third gear to rotate, the third gear drives the second gear to rotate, the second gear and the second rack are in a meshing relationship, and the second gear continues to drive the second rack to move towards the first guide rail; thus, the second rack continues to drive the third rod to move towards the direction of the electromagnetic valve; under the continued promotion of third pole, second L type pole continues to remove to the direction of keeping away from the curb plate, and then second L type pole continues control solenoid valve for flow into more overheated air in the solenoid valve from L type air duct and discharge into the atmosphere through the fifth air duct, just so can make the overheated air temperature in the stoving chamber reduce some, prevent the physical injury that overheated temperature led to the fact the pet.

After the first push plate and the second push plate are pushed, the first limiting strip and the second limiting strip limit the pedal, so that the pet on the pedal can move the pedal towards the base, the first spring is compressed, and the supporting mechanism is pressed down; the pedal drives the swinging plate to move towards the base through the connecting block and the rotating shaft; when the swing plate moves to a certain position to the base direction, one end of the swing plate, which is positioned in the locking space, is separated from the locking space, and then the swing plate cannot limit the cover and the L-shaped limiting plate, so that the function of automatic unlocking is achieved, and the pet can run out of the drying cavity at the moment. The design avoids the damage to the body of the pet caused by the overheating condition or the failure of the temperature regulator in the drying process, thereby protecting the pet.

The working process of the supporting mechanism is as follows: when the pedal moves towards the base, the two supporting strips are pressed downwards; in the process that the two supports are pressed down, one ends of the two support bars, which are connected with the sliding blocks, move in the direction away from each other, and then the two sliding blocks are driven to move in the direction away from each other; in the process that two support bars are pushed down, the intersection points of the two support bars can move down along with the intersection points, the pin can move down along with the intersection points, and then the telescopic rod is compressed. Under the reset action of first spring, the footboard can resume primary position, and then two support bars also can resume the state when not pushed down, and the telescopic link also resumes primary state. The advantage of supporting mechanism's design lies in, when arbitrary one second guide rail in each supporting mechanism received pressure, all can transmit power to the telescopic link on, so to the same to the effect that arbitrary one second guide rail of supporting mechanism received the pressure by the pressure, do not have the condition of slope atress, guaranteed that the footboard can smoothly with the horizontal state up-and-down motion.

When the pet comes out of the dryer, the pedal is restored to the original position under the action of the first spring; the user firstly pushes the second push plate and then pushes the first push plate, so that the first limit strip and the second limit strip limit the pedal again; in the process of pushing the second push plate, the second push plate moves towards the direction of the ventilation shell; the second push plate drives the second rod to move towards the ventilation shell, the third rack moves towards the ventilation shell along with the second rod, the third rack drives the third gear to rotate, the third gear drives the second gear to rotate, and the second gear drives the second rack to move towards the first gear. When the second rack moves to a certain position, the second rack is about to be disengaged from the second gear and is meshed with the first gear. Then in the process of pushing the first push plate, the first push plate drives the first L-shaped rod to move towards the square expansion opening, the first rack moves towards the square expansion opening along with the first L-shaped rod, the first rack drives the first gear to rotate, and the rotation of the first gear enables the second rack to move towards the first guide rail until the second rack moves to the original position.

Compared with the traditional dryer technology, the first push plate and the second push plate are pushed away under the very restless condition caused by overheating of the pet, the first limiting strip and the second limiting strip limit the pedal, the pedal does not limit the position of the pedal any more, the pedal drives the swinging plate to move towards the base through the connecting block and the rotating shaft, and the swinging plate is separated from the locking space, so that the function of automatic unlocking is achieved, the pet can escape from the dryer, and the injury of the pet caused by overheating is avoided; in addition, the design of the supporting mechanism ensures that the pedal can smoothly move up and down in a horizontal state.

The solenoid valve 33 controls the displacement of the fifth and sixth gas- guide tubes 39 and 40.

The opening and closing amount of the solenoid valve 33 is controlled by a second L-shaped lever 51.

When the dryer is not in operation, the pedal 55 is in contact with the first push plate 13 and the second push plate 16, and the pedal 55 is restrained by the first restraining bar 14 and the second restraining bar 17.

The length of the second rack 44 is equal to the distance between the axial centers of the first gear 45 and the second gear 46.

When the support mechanism 61 is not depressed, the distance of the two sliders 63 is the closest.

The space between the L-shaped stopper plate 8 and the lid 6 is called a locking space.

In the invention, the cover 6 swings around a hinge point by pulling the handle 7; the pendulum plate 59 and the L-shaped limit plate 8 are matched to act as: when the swinging plate 59 swings to the upper locking space, the L-shaped limit plate 8 is limited, and the cover 6 cannot be opened; when the swing plate 59 is not swung to the upper locking space, the L-shaped stopper plate 8 is not stopped, and the lid 6 can be opened. The design of the swing plate 59 with both ends symmetrical with respect to the first axis is that, when one end of the swing plate 59 swings into the locked space, the swing plate 59 can still be separated from the locked space by swinging the other end.

For the unlocking mechanism 10: the first spring 60 has a spring constant such that when a relatively light pet is placed on the pedal 55, the first spring 60 is also compressed; the four telescopic rods 56 are used for helping the pedals 55 to move smoothly in the drying cavity 12; the first spring 60 functions to allow the pedal 55 to be movably returned. One end of the rotating shaft 58 is installed on the connecting block 57, and the other end of the rotating shaft passes through the sliding square hole 19 and is installed with a swinging plate 59, so that the swinging plate 59 can rotate around the axis of the rotating shaft 58 under the stirring of a user. The pedal 55 and the first and second position-limiting strips 14 and 17 cooperate to: when the first push plate 13 and the second push plate 16 are not pushed away, the first limiting strip 14 and the second limiting strip 17 of the pedal 55 limit, and a pet on the pedal 55 cannot make the pedal 55 move towards the base 1; when the first push plate 13 and the second push plate 16 are pushed open, the first limit strip 14 and the second limit strip 17 limit the position of the pedal 55, and the pet on the pedal 55 can move the pedal 55 towards the base 1, and the first spring 60 is compressed.

The first push plate 13 is uniformly provided with a plurality of air outlet holes 25, and the functions are as follows: after the ventilation mechanism 9 feeds the hot air into the drying cavity 12, the hot air can be discharged from the air outlet 25, so that a circulating system is formed.

The first baffle 15 is used for preventing the first push plate 13 from being separated from the shell of the dryer during the movement; the second shutter 18 functions to prevent the second pusher 16 from being removed from the dryer housing during movement.

For the ventilation mechanism 9: the air pump 30 can suck the external air through the first air duct 35 and then send the external air into the electric heater 31 through the second air duct 36; after the electric heater 31 heats the outside air, the heated air flows into the square expansion port 34 from the L-shaped air duct 37, the electromagnetic valve 33 and the sixth air duct 40; the square type expansion port 34 is installed in the air intake square hole 20, so that the square type expansion port 34 is fixed, and the square type expansion port 34 also functions to rapidly diffuse the dense hot air flowing in from the sixth air duct 40 into the drying chamber 12.

Each ventilation shell 29 is provided with an air accumulation cavity 41, a plurality of air outlet pipes 42 are uniformly arranged on the lower plate surface of the air accumulation cavity 41 along the length direction of the ventilation shell 29, the air outlet pipe 42 in each ventilation shell 29 penetrates through a corresponding row of air inlet holes 21, two fourth air guide pipes 38 are symmetrically arranged on the L-shaped air guide pipe 37, one ends of the two fourth air guide pipes 38 which are not connected with the second air guide pipe 36 are respectively connected with the two ventilation shells 29, each fourth air guide pipe 38 is respectively communicated with the L-shaped air guide pipe 37 and the corresponding air accumulation cavity 41 in the ventilation shell 29, so that a small part of hot air in the L-shaped air guide pipe 37 flows into the air accumulation cavity 41 of the ventilation shell 29 from the fourth air guide pipes 38, the hot air in the air accumulating chamber 41 then flows into the drying chamber 12 through the plurality of air outlet pipes 42, the design enables the pet in the drying cavity 12 to be subjected to hot air from the top plate 3, so that the pet can be dried by the hot air in more directions; since only a small portion of the hot air flows out of the L-shaped air duct 37 and is branched by the plurality of air outlet pipes 42, the temperature of the hot air discharged through the air outlet pipes 42 is lower than that of the hot air discharged from the square-shaped expansion opening 34.

The opening and closing amount of the electromagnetic valve 33 is controlled by the second L-shaped rod 51, and the electromagnetic valve 33 controls the exhaust amount of the fifth air duct 39, so that when the dryer is not overheated, the second L-shaped rod 51 does not move away from the side plate 4, and the electromagnetic valve 33 controls the exhaust amount of the fifth air duct 39 to be zero; when the dryer is overheated, the second L-shaped lever 51 moves in a direction away from the side plate 4, and the second L-shaped lever 51 controls the solenoid valve 33 such that a part of the overheated air flowing into the solenoid valve 33 from the L-shaped air duct 37 is discharged into the atmosphere through the fifth air duct 39, and the overheated air discharged into the atmosphere through the fifth air duct 39 increases as the second L-shaped lever 51 moves in a direction away from the side plate 4.

The first guide rail 32 is installed on the top plate 3, and the third rod 50 slides in the first guide rail 32, so that the movement locus of the third rod 50 is fixed relatively. The first gear 45 is respectively engaged with the first rack 43 and the second rack 44, so that when the first push plate 13 drives the first L-shaped rod 26 to move in the direction away from the square expansion opening 34, the first rack 43 moves in the direction away from the square expansion opening 34 along with the first L-shaped rod 26, and then the first rack 43 drives the first gear 45 to rotate, and the rotation of the first gear 45 causes the second rack 44 to move in the direction of the first guide rail 32, so that the third rod 50 moves in the direction of the electromagnetic valve 33. The second L-shaped lever 51 is moved in a direction away from the side plate 4 by the pushing of the third lever 50.

The bevel gear 48 on the second gear 46 is meshed with the bevel gear 48 on the third gear 47, and the third gear 47 is meshed with the third rack 28, so that when the second push plate 16 drives the second rod 27 to move in the direction away from the ventilation shell 29, the third rack 28 moves in the direction away from the ventilation shell 29 along with the second rod 27, and then the third rack 28 drives the third gear 47 to rotate, and the third gear 47 drives the second gear 46 to rotate.

The second gear 46 and the second rack 44 cooperate to: when the first push plate 13 is not moved and only the second push plate 16 is moved, the second gear 46 and the second rack 44 cannot be engaged; when the first push plate 13 moves, the second rack 44 moves towards the first guide rail 32 under the driving of the rotation of the first gear 45, and the second rack 44 can only be meshed with the second gear 46 when moving to a certain position, and when the second push plate 16 moves, the second gear 46 rotates, and the second gear 46 continues to drive the second rack 44 to move towards the first guide rail 32.

The length of the second rack 44 is equal to the distance between the axes of the first gear 45 and the second gear 46. when the first gear 45 drives the second rack 44 to move for a certain position, the second rack 44 will be disengaged from the first gear 45 and ready to engage with the second gear 46, so that when the second gear 46 drives the second rack 44 to move, the second rack 44 will not drive the first gear 45 to rotate.

In order to prevent the ventilation mechanism 9 from being exposed and prevent the adverse effect of long-term dust accumulation on the dryer, the pet dryer of the present invention needs to be provided with a dustproof case.

When the first push plate 13 and the second push plate 16 need to be pushed, a larger pushing force is needed to push the first push plate 13 and the second push plate 16 due to a larger friction force; that is, a slight push by the pet does not move the first and second push plates 13 and 16 when the pet is not in a very restless condition.

For the unlocking mechanism 10: the first spring 60 has a spring constant such that when a relatively light pet is placed on the pedal 55, the first spring 60 is also compressed; the three support mechanisms 61 function to facilitate smooth movement of the pedals 55 in the drying chamber 12; the first spring 60 functions to allow the pedal 55 to be movably returned. One end of the rotating shaft 58 is installed on the connecting block 57, and the other end of the rotating shaft passes through the sliding square hole 19 and is installed with a swinging plate 59, so that the swinging plate 59 can rotate around the axis of the rotating shaft 58 under the stirring of a user. The pedal 55 and the first and second position-limiting strips 14 and 17 cooperate to: when the first push plate 13 and the second push plate 16 are not pushed away, the first limiting strip 14 and the second limiting strip 17 of the pedal 55 limit, and a pet on the pedal 55 cannot make the pedal 55 move towards the base 1; when the first push plate 13 and the second push plate 16 are pushed open, the first limit strip 14 and the second limit strip 17 limit the position of the pedal 55, and the pet on the pedal 55 can move the pedal 55 towards the base 1, and the first spring 60 is compressed.

For the support mechanism 61: when the pedal 55 moves toward the base 1, the two support bars 65 are pressed down; in the process that the two supports are pressed down, one ends of the two support bars 65 connected with the sliding blocks 63 move in the direction away from each other, so that the two sliding blocks 63 are driven to move in the direction away from each other; in the process that the two supporting bars 65 are pressed down, the intersection point of the two supporting bars 65 moves down, the pin 72 moves down along with the intersection point, and the telescopic rod 56 is compressed.

The specific implementation mode is as follows: when the pet dryer does not work, one end of the swinging plate 59 is positioned in the locking space, and the L-shaped limiting plate 8 and the cover 6 are limited by the swinging plate 59; the pedal 55 is in contact with the first push plate 13 and the second push plate 16, and the pedal 55 is limited by the first limiting strip 14 and the second limiting strip 17; the first spring 60 is uncompressed.

When the pet needs to be dried, the user pulls the end of the swing plate 59 which is not in the locked space, so that the end of the swing plate 59 in the locked space is separated, and the user can open the cover 6 by using the handle 7. Subsequently, the user puts the pet in the drying chamber 12, the pet being placed on the step 55; the user covers lid 6 again, and the rethread stirs balance 59 for the one end of balance 59 enters into again and locks the space in with lid 6 spacingly, prevents that the pet from running out from the drying-machine. Subsequently, the dryer starts drying the pet: the external air is sent into the electric heater 31 through the first air duct 35 and the second air duct 36 under the action of the air pump 30, after the external air is heated by the electric heater 31, the heated air flows into the square expansion port 34 from the L-shaped air duct 37, the electromagnetic valve 33 and the sixth air duct 40, and then the intensive hot air is rapidly diffused into the drying cavity 12 through the square expansion port 34; in addition, a small part of the hot air in the L-shaped air duct 37 flows into the air accumulating cavity 41 of the ventilation shell 29 from the fourth air duct 38, and then the hot air in the air accumulating cavity 41 flows into the drying cavity 12 through the plurality of air outlet pipes 42, so that the pet in the drying cavity 12 can be subjected to the hot air from the top plate 3, and the pet can be dried by the hot air in more directions. After the pet is dried, the user pulls the swing plate 59 again to separate the swing plate 59 from the locked space, so that the user can open the cover 6 by using the handle 7, and the pet can come out of the dryer.

When the pet dryer is overheated or the temperature regulator fails during the drying process, the air exhausted from the ventilation mechanism 9 will be overheated, and the pet will feel serious physical discomfort at this time, and the pet will become very restless, or even the pet will move and jump around on the pedal 55. Because the temperature of the overheated air discharged from the square expansion port 34 is higher than that of the overheated air discharged from the air outlet pipe 42, and the square expansion port 34 is larger than the air quantity discharged from the air outlet pipe 42, the pet can avoid the overheated air coming from the direction of the square expansion port 34; in the process that the pet forcibly retreats towards the first push plate 13 to avoid the overheated air from the direction of the square expansion opening 34, the first push plate 13 is pushed and the first push plate 13 moves towards the direction away from the square expansion opening 34; the first push plate 13 drives the first L-shaped rod 26 to move in the direction away from the square expansion port 34, the first rack 43 moves in the direction away from the square expansion port 34 along with the first L-shaped rod 26, and then the first rack 43 drives the first gear 45 to rotate, and the rotation of the first gear 45 causes the second rack 44 to move in the direction of the first guide rail 32; when the first gear 45 drives the second rack 44 to move a certain position, the second rack 44 is about to be disengaged from the first gear 45 and is meshed with the second gear 46; the second rack 44 drives the third rod 50 to move towards the electromagnetic valve 33; under the pushing of the third rod 50, the second L-shaped rod 51 moves away from the side plate 4, and the second L-shaped rod 51 controls the electromagnetic valve 33, so that part of the superheated air flowing into the electromagnetic valve 33 from the L-shaped air duct 37 is discharged into the atmosphere through the fifth air duct 39; at this time, since less superheated air is branched from the fifth air duct 39, the temperature of the superheated air entering the drying cavity 12 is still higher, and the pet is still in a very restless state. When the pet feels that the pet retreats away from the square expansion port 34 and still cannot avoid the overheated air, the pet can avoid the overheated air towards one side of the air port of the square expansion port 34, and the pet can forcibly avoid the overheated air from the square expansion port 34 towards the second push plate 16; in the process that the pet forcibly retreats towards the direction of the second push plate 16 to avoid the overheated air from the direction of the square expansion port 34, the second push plate 16 is pushed and the second push plate 16 moves towards the direction far away from the ventilation shell 29; the second push plate 16 drives the second rod 27 to move towards the direction far away from the ventilation shell 29, the third rack 28 moves towards the direction far away from the ventilation shell 29 along with the second rod 27, and then the third rack 28 drives the third gear 47 to rotate, the third gear 47 drives the second gear 46 to rotate, the second gear 46 and the second rack 44 generate a meshing relationship, and the second gear 46 continues to drive the second rack 44 to move towards the first guide rail 32; so that the second rack 44 continues to drive the third rod 50 to move towards the solenoid valve 33; under the continuous pushing of the third rod 50, the second L-shaped rod 51 moves continuously in the direction away from the side plate 4, and then the second L-shaped rod 51 continuously controls the electromagnetic valve 33, so that more superheated air flowing into the electromagnetic valve 33 from the L-shaped air duct 37 is discharged into the atmosphere through the fifth air duct 39, and thus the temperature of the superheated air in the drying cavity 12 is reduced to some extent, and the body injury of the pet caused by the superheated temperature is prevented.

After the first push plate 13 and the second push plate 16 are both pushed, the first limiting strip 14 and the second limiting strip 17 limit the position of the pedal 55, so that the pet on the pedal 55 can move the pedal 55 towards the base 1, the first spring 60 is compressed, and the supporting mechanism 61 is pressed down; the pedal 55 drives the swinging plate 59 to move towards the base 1 through the connecting block 57 and the rotating shaft 58; when the swinging plate 59 moves to a certain position towards the base 1, one end of the swinging plate 59 positioned in the locking space is separated from the locking space, and then the swinging plate 59 cannot limit the cover 6 and the L-shaped limiting plate 8, so that the function of automatic unlocking is achieved, and at the moment, a pet can run out of the drying cavity 12. The design avoids the damage to the body of the pet caused by the overheating condition or the failure of the temperature regulator in the drying process, thereby protecting the pet.

The working process of the supporting mechanism 61 is as follows: when the pedal 55 moves towards the base 1, the two supporting bars 65 are pressed down; in the process that the two supports are pressed down, one ends of the two support bars 65 connected with the sliding blocks 63 move in the direction away from each other, so that the two sliding blocks 63 are driven to move in the direction away from each other; in the process that the two supporting bars 65 are pressed down, the intersection point of the two supporting bars 65 moves down, the pin 72 moves down along with the intersection point, and the telescopic rod 56 is compressed. Under the reset action of the first spring 60, the pedal 55 will return to the original position, and the two support bars 65 will return to the state of not being pressed, and the telescopic bar 56 will return to the original state. The advantage of the design of the supporting mechanism 61 is that when any one of the second guiding rails 62 of each supporting mechanism 61 is pressed, the force is transmitted to the telescopic rod 56, so that the same effect as when any one of the second guiding rails 62 of the supporting mechanism 61 is pressed is achieved, no inclined force is applied, and the pedal 55 can smoothly move up and down in a horizontal state.

When the pet comes out of the dryer, the pedal 55 is restored to the original position by the return action of the first spring 60; the user causes the first limit strips 14 and the second limit strips 17 to limit the pedal 55 again by pushing the second push plate 16 first and then the first push plate 13; during the pushing of the second push plate 16, the second push plate 16 moves toward the ventilation housing 29; the second push plate 16 drives the second rod 27 to move towards the ventilation shell 29, the third rack 28 moves towards the ventilation shell 29 along with the second rod 27, and then the third rack 28 drives the third gear 47 to rotate, the third gear 47 drives the second gear 46 to rotate, and the second gear 46 drives the second rack 44 to move towards the first gear 45. When the second rack 44 is moved to a certain position, the second rack 44 is disengaged from the second gear 46 and is brought into a meshing relationship with the first gear 45. Then, in the process of pushing the first push plate 13, the first push plate 13 drives the first L-shaped rod 26 to move towards the square expansion port 34, the first rack 43 moves towards the square expansion port 34 along with the first L-shaped rod 26, and then the first rack 43 drives the first gear 45 to rotate, and the rotation of the first gear 45 causes the second rack 44 to move towards the first guide rail 32 until the second rack moves to the original position.

In conclusion, the invention has the main beneficial effects that: the first push plate 13 and the second push plate 16 are pushed away when the pet is in a very restless condition due to overheating, the first limiting strip 14 and the second limiting strip 17 limit the position of the pedal 55, the pedal 55 does not limit the position of the pedal 55 any more, the pedal 55 drives the swinging plate 59 to move towards the base 1 through the connecting block 57 and the rotating shaft 58, and the swinging plate 59 is separated from the locked space, so that the automatic unlocking function is achieved, the pet can escape from the dryer, and the injury of the pet due to overheating is avoided; in addition, the design of the supporting mechanism 61 ensures that the pedal 55 can smoothly move up and down in a horizontal state, and the invention has simple structure and better use effect.
