DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The present invention will be specifically described using the following embodiments as examples, but the embodiments described below with reference to the accompanying drawings are illustrative and are used only to explain the present disclosure, and the present invention is not limited thereto. Unless otherwise specified in this specification, mechanical devices, mechanisms, means, etc. well known to those skilled in the art can be used for these. Each embodiment can be combined based on ordinary knowledge by those skilled in the art, and configurations not specifically described in each embodiment can have the same configuration as other embodiments or a configuration suitable for that embodiment.

[0021] In describing this disclosure, any orientation or positional relationship indicated by the terms "center," "top," "bottom," "front," "back," "left," "right," "vertical," "horizontal," "ceiling," "bottom," "inside," "outside," etc., is based on the orientation or positional relationship shown in the drawings, and is merely intended to facilitate and simplify the description of this disclosure, and does not indicate or imply that a specified device or element is constructed or operates in a particular orientation or in a particular direction.

[0022] The terms "first" and "second" are used for descriptive purposes only, to indicate relative importance and not to imply a number of the technical features depicted. Thus, a feature qualified as "first" or "second" may explicitly or implicitly include one or more features. Furthermore, in this description, unless otherwise stated, "plurality" means two or more.

[0023] 1 to 30 illustrate a dryer 100 according to an embodiment of the present invention. The dryer 100 may be, but is not limited to, a pet dryer. In the description of the present application, the dryer 100 will be described as a pet dryer. As shown in FIGS. 1 to 30 , a dryer 100 according to an embodiment of the present disclosure includes a case 1.

[0024] Specifically, a first partition plate 232 is provided in the case 1, the first partition plate 232 is located in front of the rear wall 13 of the case 1, both sides of the first partition plate 232 are the drying chamber 11 and the first storage chamber 12, the first storage chamber 12 is formed between the first partition plate 232 and the rear wall 13, an impeller 21 is provided in the first storage chamber 12, the rotation axis of the impeller 21 is perpendicular to the first partition plate 232 and the rear wall 13, a first air intake port 2321 is formed on the first partition plate 232, and a second air intake port 131 is formed on the rear wall 13, and the first air intake port 2321 and the second air intake port 131 are opposite each other in the axial direction of the impeller 21.

[0025] When the impeller 21 rotates, the airflow inside the drying chamber 11 enters the first storage chamber 12 through the first air intake 2321 under the action of the impeller 21 and flows into the drying chamber 11, and the airflow outside the dryer 100 enters the first storage chamber 12 through the second air intake 13 under the action of the impeller 21 and flows into the drying chamber 11, thereby realizing internal and external circulation of air by one impeller 21.

[0026] For example, in the examples of Figures 1, 4, 5, and 7, the case 1 may be a square case, the impeller 21 is installed at the top of the first storage chamber 12, and the first air inlet 2321 and the second air inlet 13 are both opposite to each other in the axial direction of the impeller 21. When the pet is dried in the dryer 100, the impeller 21 rotates. At this time, the airflow in the drying chamber 11 passes through the first air inlet 2321 along the axial direction and enters the impeller 21, while the airflow outside the dryer 100, for example the pet dryer, passes through the second air inlet 131 along the axial direction and enters the impeller 21. Then, the airflow inside the impeller 21 flows into the first storage chamber 12 along the radial direction of the impeller 21, and is compressed in the first storage chamber 12, and finally flows into the drying chamber 11 under the action of the impeller 21 to dry the pet. As a result, compared to conventional pet drying boxes, the present invention can simultaneously achieve internal and external circulation of air with only one impeller 21, replenishing fresh air, making pets safer, increasing the amount of intake air of the dryer 100, reducing the loss of wind energy, and improving the drying efficiency of the dryer 100. In addition, the single impeller 21 can avoid uneven distribution of excess hot and cold air in the case 1 caused by the impeller 21, effectively reduce noise, reduce the noise during operation of the dryer 100, and reduce the manufacturing cost of the dryer 100.

[0027] Here, by providing the impeller 21 in the first storage chamber 12 between the rear wall 13 of the case 1 and the first partition plate 232, the airflow outside the dryer 100 can be smoothly introduced when the impeller 21 is rotated, thereby realizing ventilation inside and outside the dryer 100 and avoiding potential safety risks associated with the impeller 21 due to the occurrence of liquid leakage from the bottom wall of the case 1, thereby improving the safety of use of the dryer 100 and ensuring the service life of the dryer 100.

[0028] In the dryer 100 of the present invention, for example, a pet dryer, the first partition plate 232 is positioned in front of the rear wall 13 of the case 1 to divide the inside of the case 1 into a drying chamber 11 and a first storage chamber 12, the first storage chamber 12 is formed between the first partition plate 232 and the rear wall 13 of the case 1, the impeller 21 is provided in the first storage chamber 12, the first air intake 2321 is formed on the first partition plate 232, the second air intake 131 is formed on the rear wall 13, and the first air intake 2321 and the second air intake 131 are respectively opposed to each other in the axial direction of the impeller 21. This increases the intake amount of the dryer 100, reduces the loss of wind energy, improves the drying efficiency of the dryer 100, and avoids unevenness of the hot and cold air in the case 1 due to the extra impeller 21, reduces noise during operation of the dryer 100, and reduces the manufacturing cost of the dryer 100.

[0029] According to the present invention, as shown in Fig. 13, an impeller casing 23 is provided between the first partition plate 232 and the rear wall 13, the impeller 21 is provided in the impeller casing 23, and an air passage 231 is formed between the impeller 21 and the impeller casing 23. When the impeller 21 rotates, the airflow in the drying chamber 11 flows into the drying chamber 11 through the first air intake 2321 and the air passage 231, and the airflow outside the dryer 100 flows into the drying chamber 11 through the second air intake 131 and the air passage 231. When the impeller 21 rotates, the impeller 21 blows the airflow flowing through the impeller 21 radially into the air passage 231, and the airflow is compressed in the air passage 231. The compressed airflow can flow into the drying chamber 11 under the guiding action of the air passage 231. This makes it possible to avoid loss of intake air volume and to allow as much of the airflow passing through the impeller 21 as possible to flow into the drying chamber 11, thereby improving the drying efficiency of the dryer 100.

[0030] According to the present invention, as shown in Figures 1, 3, 5 and 7, a second partition plate 3 is provided in the case 1, and a second accommodation chamber 14 directly communicating with the air passage outlet 2311 is formed between the second partition plate 3, the position of the air passage outlet 2311 of the air passage 231 corresponding to the impeller casing 23, and the inner wall of the case 1, and the air passage outlet faces the bottom of the dryer. An outlet 31 is formed on the second partition plate 3, and the drying chamber 11 is located above the second partition plate 3. With the above-mentioned structure, when the impeller 21 rotates, the airflow in the drying chamber 11 passes through the first air intake 2321, the air passage 231, the second accommodation chamber 14, and the air passage outlet 13 in order to flow into the drying chamber 11, and the airflow outside the dryer 100 passes through the second air intake 131, the air passage 231, the second accommodation chamber 14, and the air passage outlet 13 in order to flow into the drying chamber 11. As a result, the airflow flowing out from the air passage outlet 2311 can flow directly into the second storage chamber 14, improving the drying efficiency. In addition, when the pet is on the second partition plate 3, the airflow in the second storage chamber 14 flows through the outlet 31 to the pet's position, and the pet can be dried. At this time, the airflow that performs the drying action is blown onto the pet's abdomen, improving the ventilation effect of the case 1, shortening the operation time of the drying process, further improving the drying efficiency, and improving the drying effect. In addition, the second partition plate 3 releases moisture and dirt from the pet's body to the bottom wall of the case 1 through the outlet 31 by gravity, ensuring the cleanliness of the drying chamber of the case 1. A ventilation air passage is formed between the first partition plate and the bottom wall of the dryer, specifically, there is a certain gap between the first partition plate and the bottom of the dryer to form a ventilation air passage, and the second partition plate is provided at a certain distance above the bottom wall of the dryer, so that the second storage chamber can not only form an air passage, but also has the function of collecting moisture that has fallen onto the pet being dried, etc., and the entire dryer can be made more compact.

[0031] 11-17 and 1, the second partition 3 is detachably provided at the bottom of the case 1, which makes it easy to separate the second partition 3 from the case 1 and to wash the bottom wall of the case 1 and the second partition 3, preventing puddles and dirt from forming in the case 1, providing a clean drying environment, and improving the comfort of pets when drying. Also, if the second partition 3 is damaged, it can be easily removed from the case 1 to replace it with a new second partition 3, which can extend the service life of the dryer 100.

[0032] Furthermore, the second partition plate 3 and the case 1 are detachably connected by at least one engagement assembly 4, so that the second partition plate 3 and the case 1 can be detachably engaged, making it easier to remove the second partition plate 3 and improving the efficiency of attachment and detachment. This installation method allows the user to more easily remove the second partition plate 3 to clean the bottom wall of the case 1, reducing the user's efforts. Of course, the second partition plate 3 and the case 1 can be detachably connected by a method such as fitting a hole and a column, inserting and fitting, etc., but this is not limited thereto.

[0033] The engagement assembly 4 includes a snap 41 and a fitting groove 42, a groove portion 32 is provided on the second partition plate 3, the snap 41 is provided on the inner wall of the groove portion 32, and the snap 41 has a snap portion 411. An extension portion 15 extending toward the snap 41 is provided on the case 1, a fitting groove 42 is formed between the extension portion 15 and the inner wall of the groove portion 32, and the snap 411 is fitted into the fitting groove 42. As shown in Figures 11 to 17, the notch of the groove portion 32 can be opened toward the case 1 to facilitate engagement with the fitting groove 42 provided in the case 1. The extension portion 15 can form the fitting groove 42 together with the bottom wall of the groove portion 32. As a result, the snap portion 411 fits into the space formed by the extension portion 15 and the groove portion 32, thereby realizing an engagement connection between the second partition plate 3 and the case 1. This allows the user to more conveniently remove the second partition plate 3 to clean, wash and replace the bottom of the case 1, further improving comfort when drying pets and improving user convenience. In addition, for example, if the snap 41 and the inner wall of the recessed groove portion 32 are integrally molded, the structural reliability of the snap 41 can be improved.

[0034] In another embodiment of the present invention, the cross-sectional shape of the snap 41 is substantially U-shaped, and at least a portion of the opposing sides of the U-shape may be spaced apart, so that the user can push the two sides of the U-shaped snap closer to each other, separating the snap 41 from the fitting groove 42 and allowing the snap 41 to slip out of the fitting groove. The cross-section of the snap 41 is not limited to this, and may have other shapes.

[0035] One end of the snap 41 is connected to the inner wall of the recessed groove portion 32, and the other end of the snap 41 has a snap portion 411, and a stopper protrusion 412 is provided on the side of the snap 41 facing the extension portion 15, and the stopper protrusion 412 and the snap portion 411 are located on both sides in the thickness direction (for example, the up-down direction in FIG. 17) of the extension portion 15. This allows the extension portion 15 to engage between the stopper protrusion 412 and the snap portion 411 during the actual installation process, preventing rattling of the second partition plate 3 and enabling the second partition plate 3 to be stably installed to the case 1.

[0036] 15, the surface of the stopper protrusion 412 facing the side wall of the case 1 extends from bottom to top at an incline toward the side wall of the case 1, and the thickness of the stopper protrusion 412 gradually increases from one end close to the bottom of the case 1 to one end away from the bottom of the case 1, so that the surface of one side of the stopper protrusion 412 facing the side wall of the case 1 is formed as an inclined surface. This not only increases the contact area between the extension 15 and the stopper protrusion 412, but also reduces the space occupied by the stopper protrusion 412 so that the snap 41 can easily be removed from the fitting groove 42 together with the stopper protrusion 412. Furthermore, the end face of the one end of the stopper protrusion 412 away from the bottom of the case 1 fits into the bottom of the extension 15, thereby increasing the attachment reliability of the extension 15 and the stopper protrusion 412. The stopper protrusion 412 can also be molded integrally with the snap 41 to increase the reliability of the structure.

[0037] Furthermore, a first concave surface 151 that is concave downward is formed on a part of the upper surface of the extension portion 15. When attaching or separating the snap 41 and the fitting groove 42, the user can place his / her hand on the first concave surface 151, which improves comfort when attaching or removing the device. For example, the first concave surface 151 may be an arcuate surface, which can further improve comfort.

[0038] 18, in another embodiment of the present invention, a through hole 413 is formed on the snap portion 411, thereby reducing the weight of the snap portion 411 and realizing a lightweight engagement assembly 4. In addition, when a user presses the snap portion 411 to separate the snap portion 411 from the snap groove 42, the snap portion 411 deforms toward the through hole 413, thereby reducing the force with which the user presses the snap portion 411, making it easier for the user to quickly attach and detach the second partition plate 3.

[0039] 16, at least a part of the surface of the snap portion 411 facing the side wall of the case 1 is formed with a second concave surface 414 that is concave in a direction away from the side wall of the case 1. Here, the second concave surface 414 can be designed to have other shapes according to the needs of the user. For example, by making the second concave surface 414 into an arcuate surface, the user's hand can easily fit to the second concave surface 414 when gripping it, the contact area between the two is increased, and the snap portion 411 can be pressed with a smaller force, thereby further improving the practicality of the snap portion 411.

[0040] The snap 41 may be an elastic snap, and such a snap 41 elastically deforms when a user applies force to the snap 41, which helps the user to press the snap 41 to separate the snap 41 from the engagement groove 42, facilitating attachment / detachment or attachment of the two. In addition, since the elastic member has excellent recovery performance, when the user releases the force from the snap 41, the snap 41 can easily attach and detach the snap 41 to the engagement groove 42 due to its own recovery ability.

[0041] In another embodiment of the present invention, the engagement assembly 4 is located at the front of the case 1. For example, when a user opens the case 1, the second partition plate 3 and the case 1 can be attached and detached by attaching and detaching the snap 41 and the fitting groove 42. This can improve the convenience and efficiency of attachment and detachment.

[0042] The engagement assembly 4 may be configured so that a plurality of engagement assemblies 4 can be arranged at intervals. For example, when there are two engagement assemblies 4, the two engagement assemblies 4 are provided on both sides of the width direction of the case 1 (for example, the left-right direction shown in FIG. 1), and when attaching or detaching, the user can hold the two engagement assemblies 4 with both hands and attach or detach the second partition plate 3 from both sides of the second partition plate 3, thereby reducing the difficulty of removing the second partition plate 3 and making the detachable connection between the second partition plate 3 and the case 1 stronger.

[0043] In addition, a protrusion that increases frictional force can be added to the second partition plate 3. The protrusion can more stably dry the pet on the second partition plate 3. The shape of the protrusion may be rectangular and is not limited here.

[0044] In another embodiment of the present invention, the distance between the second partition 3 and the bottom wall of the case 1 is 1-2 cm (including end values). Here, "distance" means the distance from the bottom surface of the second partition 3 to the top of the bottom wall of the case 1. The distance between the second partition 3 and the bottom wall of the case 1 may be 1 cm. Or the distance between the second partition 3 and the bottom wall of the case 1 may be 2 cm. With such an installation, the height of the drying chamber 11 and the second containing chamber 14 becomes more reasonable, and the space for the pet to move around is secured, and the ventilation in the case 1 is improved, and the air flow in the case 1 is improved, so that the drying efficiency can be improved.

[0045] Also, as shown in Figures 15 to 17, at least one support 5 is provided on the bottom wall of the case 1, and the support 5 can support the second partition 3. For example, there may be multiple support members 5, and the multiple support members 5 may be provided on the edge and center of the second partition 3, respectively. Here, the support members 5 provided on the edge of the second partition 3 are provided symmetrically, thereby ensuring the support effect of the second partition 3 and the mounting stability of the second partition 3. There is a certain distance between the second partition 3 and the bottom wall of the case 1, so that the second partition 3 is suspended in the air in the case 1, and the second partition 3 itself has a certain weight, and furthermore, the pet lies on the second partition 3, so that the support member 5 can support the second partition 3 and the pet on the second partition 3 while ensuring a good drying effect.

[0046] For example, the number of supports 5 may be four, and the four supports 5 are installed at intervals, one end of the supports 5 is connected to the bottom wall of the case 1, and the other end of the supports 5 is supported by the second partition plate 3, so that the second storage chamber 14 and the first storage chamber 12 can be easily connected. As a result, the airflow flows through the first storage chamber 12 to the second storage chamber 14, and then through the air outlet 31 into the drying chamber 11 to dry the pet. The supports 5 installed at intervals do not interfere with the airflow and do not obstruct the airflow. When the pet lies on its stomach on the second partition plate 3, the air can dry the pet's abdomen and the like through the air outlet 31 on the second partition plate 3, and the drying efficiency is high. The supports 5 may be a support stand or a support column.

[0047] Furthermore, the second partition plate 3 can be detachably connected to the support member 5 via the engagement assembly 4. The snaps 41 of the engagement assembly 4 are provided on the second partition plate 3, and the fitting grooves 42 of the engagement assembly 4 are provided on the support member 5. When installed, the snaps 41 of the second partition plate 3 can be engaged into the fitting grooves 42 of the support member 5, thereby detachably connecting the second partition plate 3 and the case 1.

[0048] 16, the second partition plate 3 may be formed with an attachment hole 33, and the end of the support material 5 is fitted into the attachment hole 33. This allows the attachment hole 33 to function as a positioning hole, making it easy to attach the support material 5 to the second partition plate 3, and not only improving the attachment efficiency, but also the fitting structure of the attachment hole 33 and the support material 5 can increase the support stability of the support material 5 and ensure the comfort of the pet during drying.

[0049] In addition, the number of mounting holes 33 may be multiple, and the multiple mounting holes 33 correspond one-to-one to the multiple support materials 5, and the multiple mounting holes 33 are installed at intervals. For example, the number of mounting holes 33 may be four, and the four mounting holes 33 correspond one-to-one to the four support materials 5. In this way, when attaching the second partition plate 3, the mounting hole 33 is directly aligned with the upper end of the support material 5, and at least a part of the upper end of the support material 5 extends into the mounting hole 33, which can prevent the second partition plate 3 and the support material 5 from being separated, and can improve the connection stability of the second partition plate 3 and the support material 5. Furthermore, by supporting the second partition plate 3 through the support material 5, the second partition plate 3 will not fall off when a pet is in the drying chamber 11, and the overall structural strength of the dryer 100 can be improved.

[0050] According to another embodiment of the present invention, as shown in FIG. 17, a mounting assembly 6 is provided for mounting the second partition plate 3 in the case 1, which can prevent the second partition plate 3 from being separated from the case 1 and further improve the structural stability of the second partition plate 3. Furthermore, as shown in FIG. 19, the mounting assembly 6 may include a sliding opening 61 and a first mounting groove 62, and the second partition plate 3 can slide into the first mounting groove 62 along the sliding opening 61 in the case 1. This reduces the difficulty of attaching and detaching the second partition plate 3 and the case 1, and improves the structural stability of the second partition plate 3. For example, the sliding opening 61 may be a stop opening. The first mounting groove 62 may be an elongated groove. There may be two sliding openings 61, and the two sliding openings 61 are provided on opposite sides in the case 1, and the first mounting groove 62 is provided at the bottom in the case 1, and its position corresponds to the sliding opening 61. When the first mounting groove 62 is provided on one side of the bottom inside the case 1, the fitting groove 42 in the engagement assembly 4 may be provided on the other side of the first mounting groove 62.

[0051] Specifically, when attaching the second partition plate 3 to the case 1, the second partition plate 3 can be slid along the sliding opening 61 up to the first mounting groove 62. Furthermore, since the second partition plate 3 is engaged with the case 1 via the engagement assembly 4, the second partition plate 3 can be easily inserted into the case 1 by the mounting assembly 6, and the efficiency of mounting the second partition plate 3 to the case 1 can be improved.

[0052] 19, a first rib 621 and a second rib 622 are provided on the rear wall 13 inside the case 1, and the rear ends of the first rib 621 and the second rib 622 are both connected to the rear wall 13 of the case 1, and the second rib 622 is located below the first rib 621. As a result, the lower surface of the first rib 621, the upper surface of the second rib 622, and the rear wall 13 inside the case 1 form a first mounting groove 62, and the tip of the first rib 621 and the tip of the second rib 622 form the slide-in opening 61.

[0053] As a result, when actually installing, the second partition plate 3 can easily slide into the case 1 along the sliding opening 61 until one end of the second partition plate 3 extends into the first mounting groove 62, and the first mounting groove 62 can restrict the second partition plate 3, thereby preventing rattling or displacement of the second partition plate 3 and enhancing the structural stability of the second partition plate 3.

[0054] Furthermore, the width of the second rib 622 in the front-rear direction (for example, the dimension in the front-rear direction as shown in FIG. 17) is greater than the width of the first rib 621 in the front-rear direction. This increases the contact area between the second rib 622 and the second partition plate 3 so as to ensure stable support for the second partition plate 3 when the second partition plate 3 is attached in the first mounting groove 62, and also facilitates attachment and detachment, allowing the user to attach and detach the second partition plate 3 more quickly, and prevents the first rib 621 from affecting the attachment and detachment of the second partition plate 3, reducing the difficulty of attaching and detaching the second partition plate 3, and improving the attachment efficiency of the dryer 100.

[0055] In another embodiment of the present invention, the case 1 is provided with a limiting component that is a stopper that restricts the movement of the second partition plate 3. This makes it possible to more reliably fix the second partition plate 3 using the limiting component, prevent the second partition plate 3 from being displaced, effectively dry the pet on the second partition plate 3, and improve the drying efficiency. Furthermore, even if the pet moves on the second partition plate 3, no rattling or movement occurs between the second partition plate 3 and the case 1.

[0056] Furthermore, the stopper may be a restricting hole. The second partition plate 3 is provided with a first restricting block 7 that can be engaged with the restricting hole, and the restricting hole and the first restricting block 7 are engaged or inserted into each other to ensure the mounting stability of the second partition plate 3 and the case 1. For example, the restricting hole may be a rectangular hole, and the first restricting block 7 may be a nest that can be engaged with a small rectangular hole. In an embodiment of the present invention, the restricting holes may be four. The four restricting holes are symmetrically arranged on both sides facing each other in the case 1, and the first restricting blocks 7 on the second partition plate 3 are also four, and the four first restricting blocks 7 are symmetrically arranged on both sides facing the second partition plate 3. This allows the first restricting blocks 7 on the second partition plate 3 to be engaged with the restricting block holes on the case 1, which can more reliably fix the second partition plate 3 and avoid the displacement of the second partition plate 3, effectively drying the pets on the second partition plate 3 and improving the drying efficiency.

[0057] According to an embodiment of the present invention, the air outlet 31 includes a plurality of air outlets. The second partition 3 includes a partition body 34 and two partition segments 35, the two partition segments 35 are respectively provided on the left and right sides of the partition body 34, the two partition segments 35 extend upward from the bottom to the top at an inclination away from the center of the partition body 34, and the two partition segments 35 and the partition body 34 are each formed with a plurality of air outlets. As shown in Figures 1, 3 and 11, the second partition 3 may be a U-shaped partition, and each partition segment 35 may be a protruding arc-shaped partition away from the partition body 34, and the plurality of air outlets are covered by the U-shaped partition, and the pet is placed on the U-shaped partition body 34, and the airflow blows out from the bottom to the top through the plurality of air outlets on the partition body 34, which is convenient for drying the pet's abdomen. The plurality of blowing holes of each partition plate segment 35 are arranged at intervals in the longitudinal direction of the partition plate segment 35, and the plurality of blowing holes on the two partition plate segments 35 blow airflow obliquely upward, which makes it easy to dry the back and other parts of the pet, and can dry the pet's hair without blind spots. Furthermore, the wind power utilization rate of the dryer 100 is improved, the drying speed is fast, and the drying effect is high. Here, by providing the two partition plate segments 35 so as to extend obliquely upward from bottom to top in a direction away from the center of the partition plate body 34, the airflow in the second storage chamber 14 can be guided to reduce the wind resistance of the airflow in the second storage chamber 14, and the airflow can be rapidly blown into the drying chamber 11. The shape of the second partition plate 3 can be installed as close as possible to the bottom wall of the case 1 based on the shape of the bottom wall of the case 1, so that the second partition plate 3 and the case 1 can be better fitted together.

[0058] In addition, the shape of the multiple outlet holes on the partition plate main body 34 may be rectangular, thereby increasing the airflow ejection area, and the shape of the multiple outlet holes on each partition plate segment 35 may be circular, thereby assisting in the airflow ejection, and the synergistic effect of these two elements achieves a high drying effect.

[0059] In another embodiment of the present invention, the partition body 34 is provided with a plurality of bosses 341, the plurality of bosses 341 are provided on the upper surface of the partition body 34 to separate each other, the plurality of blowing holes on the partition body 34 include a plurality of first blowing holes 311 and a plurality of second blowing holes 312, the plurality of first blowing holes 311 are formed on the partition body 34, and the plurality of second blowing holes 312 are formed on the plurality of bosses 341. In this way, the airflow can be blown from the second accommodation chamber 14 into the drying chamber 11 through the plurality of first blowing holes 311 and the plurality of second blowing holes 312. Furthermore, by providing a boss 341 and forming a second blowing hole 312 on the boss 341, the upper end of the first blowing hole 311 and the upper end of the second blowing hole 312 are at different heights and the blowing heights of the first blowing hole 311 and the second blowing hole 312 are different. This makes it possible to completely block all blowing holes when a pet is placed on the second partition plate 3, prevents insufficient airflow into the drying chamber 11, and makes the drying effect of the pet more effective.

[0060] In another embodiment of the present invention, a drainage hole (not shown) is formed in the bottom wall of case 1. By providing the drainage hole, water inside case 1 can be easily drained to the outside of case 1, thereby ensuring a dry environment inside case 1.

[0061] Dryer 100 may further include a plug (not shown), which is used to open and close the drain hole and is detachably attached to the drain hole. When the plug is attached to the drain hole, the plug closes the drain hole and water in case 1 cannot be discharged through the drain hole. For example, when a pet is placed in case 1 to dry, the plug is attached to the drain hole to close the drain hole and prevent airflow from dispersing out of case 1 through the drain hole, thereby ensuring drying efficiency and effectiveness.

[0062] When the plug is removed from the drain hole, the drain hole is opened, allowing water inside the case 1 to flow through the drain hole to the outside of the case 1. The plug and the drain hole are detachably connected, making it easy to attach and detach the plug and allowing the user to easily open and close the drain hole.

[0063] According to another embodiment of the present invention, a heater unit 80 is provided at the air passage outlet 2311 of the air passage 231. As shown in FIG. 4, the heater unit 80 extends in the longitudinal direction of the outlet of the air passage 231, and increases the flow speed of the air flow, thereby increasing the utilization rate of the wind power and increasing the temperature of the air flow in the second storage chamber 14, thereby realizing a heating and drying function. The pet in the dryer 100 is made comfortable, and the dryer 100 blows out only cool air, so that the pet does not get sick, and the drying efficiency is improved. In addition, when the dryer 100 is used as a gauge, the dryer 100 can be used in combination with the impeller 21 and the heater unit 80 so that the dryer 100 blows out warm air in winter and cool air in summer, making the pet more comfortable in the dryer 100. The heater unit 80 may be a PTC (Positive Temperature Coefficient) heater.

[0064] According to another embodiment of the present invention, the first partition 232 is provided with a negative ion generator, and the output end of the negative ion generator extends into the first receiving chamber 12. Thus, when the negative ion generator is in operation, the negative ions generated by the negative ion generator can flow into the drying chamber 11 through the output end, and sterilize the airflow in the drying chamber 11.

[0065] An ozone sterilization device is provided on the heater unit 80. For example, the ozone sterilization device may be an ozone sterilizer or an ozone generator, and pet clothes, toys, etc. can be placed in the case 1 and sterilized with ozone, thereby further improving the functionality and practicality of the dryer 100.

[0066] Furthermore, air passage 231 is a spiral air passage. As shown in Fig. 13, the shape of the spiral air passage on first partition plate 232 is a spiral line shape. By making air passage 231 a spiral air passage in this way, the amount of air at air passage outlet 2311 can be increased.

[0067] Furthermore, at least a part of the shape of impeller casing 23 on first partition plate 232 is a spiral shape. For example, in the example of Fig. 13, at least a part of the shape of impeller casing 23 on first partition plate 232 is an Archimedes spiral shape. This makes it possible to shorten the length of air passage 231 by utilizing the principle of Archimedes spiral, reduce the loss of wind energy, and provide the airflow blown out of air passage 231 with a certain impact force, thereby improving the drying function of dryer 100.

[0068] 13, air passage 231 has air passage outlet 2311, and the cross-sectional area of ​​at least a part of air passage 231 gradually increases along the circumferential direction of impeller 21 toward air passage outlet 2311. As a result, the airflow is pushed from a narrow area to a wide area along the extension direction of air passage 231, and finally the pressure decreases and the airflow is blown out of air passage outlet 2311, and the airflow blowing out from air passage outlet 2311 has a certain impact force, which can improve the drying efficiency of dryer 100.

[0069] According to the embodiment of the present invention, as shown in Fig. 4, the impeller casing 23 is provided on either the first partition plate 232 or the rear wall 13, but the impeller casing 23 may be provided on both the first partition plate 232 and the rear wall 13. This allows the structure of the dryer 100 to be made more compact.

[0070] In addition, the dryer 100 also includes a motor holder 233. The impeller casing 23 includes a first impeller casing 2322 and a second impeller casing 2331, where the first impeller casing 2322 is disposed on the first partition plate 232, and the second impeller casing 2331 is disposed on the motor holder 233. The second impeller casing 2331 and the first impeller casing 2322 together form an impeller accommodating chamber for accommodating the impeller 21. As shown in FIG. 4, the motor holder 233 is disposed between the impeller 21 and the rear wall 13, and the motor 22 is disposed in the impeller accommodating chamber, the output shaft of the motor 22 is fixed to the impeller 21, the motor 22 is mounted on the second impeller casing 2331, and the second impeller casing 2331 can support the motor 22, which makes the motor 22 more stable and reliable during operation and improves the drying effect. Here, the motor holder 233 may be an annular motor holder that fits the first impeller casing 2322. The motor 22 may be located in the inner ring of the annular motor holder, and the annular motor holder is provided with a vent hole parallel to the rotation axis of the impeller 21, so that the airflow outside the dryer 100 can flow to the impeller 21 through the second air inlet 131 and the vent hole.

[0071] Furthermore, the motor holder 233 is formed with an intake hole penetrating in the axial direction of the impeller 21, and the motor holder 233 is hermetically connected to the rear wall 13 on the outer circumferential side of the intake hole, so that the outside air sucked into the impeller 21 passes through the second intake port 13 and the intake hole in that order before entering the impeller 21 housing chamber. As a result, the outside air passes directly through the second intake port 13 and the intake hole on the motor holder 233 before entering the impeller housing chamber, thereby improving drying efficiency. In another embodiment of the present invention, the motor holder 233 is detachably connected to the first partition plate 232. This makes it easy to attach and detach the motor holder 233.

[0072] 4, the rear surface of the first partition plate 232 extends rearward and is molded to the first impeller casing 233. This arrangement allows the first impeller casing 233 and the first partition plate 232 to be molded integrally, which can reduce the installation process of the dryer 100 and further improve the installation efficiency of the dryer 100.

[0073] In addition, impeller 21 may be a forward-inclined impeller, which operates by utilizing centrifugal force to increase the pressure of the airflow, compressing the airflow within air passage 231 and giving the airflow ejected from air passage outlet 2311 a certain impact force, thereby achieving a more effective drying function.

[0074] According to an embodiment of the present invention, the shaft of the impeller 21 penetrates in the front-rear direction. For example, the hub of the impeller 21 may be formed with a plurality of vent holes penetrating therethrough, and the plurality of vent holes are provided at intervals in the circumferential direction of the impeller 21. During operation of the impeller 21, the airflow inside and outside the case 1 enters the impeller 21 along the axial direction of the impeller 21, and then the airflow is radially blown out from the blades of the impeller 21, and the airflow is accumulated in the air passage 231 and compressed, and can flow into the drying chamber 11 of the case 1 through the air passage outlet 2311. Here, the vent holes allow the external airflow to flow more smoothly into the impeller 21, increasing the airflow rate flowing into the impeller 21, and making the internal and external gas circulation of the dryer 100 more thorough, thereby providing a more comfortable drying environment.

[0075] In another embodiment of the present invention, the first air inlet 2321 is provided with a hair filter, and the second air inlet 13 is provided with a dust filter 16. As shown in Fig. 4, the dust filter 16 is provided on a side farther from the inside of the case 1 than the impeller 21, and the hair filter is provided on a side closer to the inside of the case 1 than the impeller 21. Here, the dust filter 16 may be directly provided on the second air inlet 13 of the rear wall 13 of the case 1. When drying a pet in the dryer 100, pet hair is likely to fall out, so the hair filter can filter the hair that has entered the airflow of the impeller 21 in the case 1, and ensure that the impeller 21 operates normally. Moreover, since dryer 100 is used in crowded places such as shops and outdoors, there is inevitably dust in the airflow outside case 1. Dust filter 16 filters out dust that has entered the airflow of impeller 21 from outside case 1, allowing impeller 21 to effectively realize the internal and external suction function, and also filters out foreign matter sucked into the airflow, thereby extending the service life of dryer 100 and providing dryer 100 with cleaner internal air and a more comfortable environment.

[0076] In addition, in the dryer 100, the transition portion between the position of the air passage outlet 2311 of the air passage 231 and the bottom wall of the case 1 has a chamfered shape, specifically, it can be made into a quarter of a circle, thus enabling the air to be guided effectively and smoothly and effectively reducing noise.

[0077] According to an embodiment of the present invention, at least one petting opening 171 is formed on the case 1, and a petting door 172 is provided for opening and closing the petting opening 171. As shown in FIG. 1 and FIG. 3, when drying a pet inside the case 1, a user pushes the pet door 172 toward the inside of the case 1 or pulls it from the outside of the case 1 to open the petting door 172 and open the petting opening 171, and then extends his / her hand to the petting opening 171 and pets the pet inside the case 1, thereby calming the pet's emotions, smoothly progressing the drying process, improving the drying effect, and increasing the comfort of the pet during drying. In addition, the user can put his / her hand into the petting opening 171 to pet the pet's hair and check the degree of drying, so that the user can determine whether the drying is complete and the time required for drying can be determined, thereby improving the drying efficiency. The petting door 172 covers the petting opening 171, so that the pet's limbs do not protrude from the petting opening 171 and the pet's whole body is dried. The opening area of ​​the petting opening 171 can be designed to be small so that only a human hand can enter and exit, thereby preventing the pet from escaping from the case 1.

[0078] 1, a user can open the petting opening 171 by pushing open the petting door 172 from the outside of the case 1 toward the inside of the case 1. This design not only simplifies the user's operation, but also prevents a pet from opening the petting door 172 from inside the case 1.

[0079] 23 and 24, in order to facilitate opening and closing of the pat door 172, the pat door 172 and the case 1 are pivotally connected via a pivot assembly 9, which allows light and convenient opening and closing, enhances the connection stability between the case 1 and the pat door 172, and enhances the reliability of the pat door 172 when pivoting. The pivot assembly 9 includes a first mounting part 91, a second mounting part 92, and a pivot shaft 93, the first mounting part 91 being provided on the case 1, the second mounting part 92 being provided on the pat door 172, and the pivot shaft 93 being installed to pass through the first mounting part 91 and the second mounting part 92 so as to enable the pat door 172 to pivot. Thus, by providing the first mounting part 91 and the second mounting part 92, the installation of the pivot shaft 93 is facilitated, and stability when pivoting is improved.

[0080] 23, the dryer 100 further includes at least one torque spring 94. The torque spring 94 is fitted onto the pivot shaft 93, and the torque spring 94 constantly presses the stroking door 172 in a direction to close the stroking opening 171. For example, the torque spring 94 has an abutment portion, and one end of the abutment portion can abut against the side wall of the case 1, and the other end of the torque spring 94 can abut against the second mounting portion 92. The pivot shaft 93 can pass through the torque spring 94 in the longitudinal direction of the torque spring 94, and both ends of the pivot shaft are connected to both ends of the mounting stand, respectively.

[0081] Here, the torque spring 94 has a structure that mechanically stores force and has a self-resetting function, and since the torque spring 94 has a certain force, the pet door 172 is fixed on it, and a certain force is required to open the pet door 172, making it difficult for the pet to open it by itself, which allows the pet's entire body to dry inside the case 1 and improves the drying effect. When the human hand leaves the pet opening 171, the pet door 172 is automatically reset by the torque spring 94 and continues to cover the pet opening 171, preventing the pet from escaping and foreign objects from entering the case 1 and preventing a decrease in the drying effect.

[0082] According to an embodiment of the present invention, a door 8 is provided to open and close one side of the case 1. For example, when the front side of the case 1 is open, the door 8 can be provided on the front side of the case 1 to open and close the front side of the case 1 in order to facilitate the user to place a pet in the case 1 or take a pet out of the case 1. Alternatively, when the top side of the case 1 is open, the door 8 can be provided on the top side of the case 1 to open and close the top side of the case 1 in order to reduce the possibility of the pet escaping. The specific mounting position of the door 8 on the case 1 may be determined according to actual needs and is not limited herein.

[0083] 23, the first mounting portion 91 includes two mounting lugs 911 spaced apart from each other. The second mounting portion 92 is located between the two mounting lugs 911, and the pivot shaft 93 passes through the two mounting lugs 911 and the second mounting portion 92, which improves the reliability of the mounting between the pivot shaft 93 and the first mounting portion 91 and between the pivot shaft 93 and the second mounting portion 92, and allows the cat door 172 to rotate more smoothly.

[0084] The two mounting parts limit the position of the torque spring 94 and prevent the torque spring 94 from coming off the pivot assembly 9, the pivot shaft 93 can prevent the torque spring 94 from being deformed, the connection between the petting door 172 and the case 1 is more secure, and the effective service life of the dryer 100 can be extended.

[0085] According to an embodiment of the present invention, as shown in FIG. 1 and FIG. 3, an opening 17 is formed in the case 1, a removable observation window 10 is provided in the opening 17, and the observation window 10 is formed in the petting opening 171. By providing the observation window 10, the user can easily observe the internal environment of the case 1, and the user can observe the state of the pet without opening the petting door 172, so that the user can know the pet's mood at any time, make the drying process smoother, make the pet happy, and improve the practicality of the dryer 100. For example, the observation window 10 may be made of a transparent material so that the state of the pet inside the case 1 can be more easily monitored. The observation window 10 can be made to fit the shape of the petting door 172. For example, the observation window 10 may be made into a ring shape.

[0086] 20, one end of the stroking door 172 (e.g., the upper end shown in FIG. 1) and the observation window 10 are pivotally connected via a pivot assembly 9, and a lock assembly 20 is provided between the other end of the stroking door 172 (e.g., the lower end shown in FIG. 1) and the observation window 10. When the lock assembly 20 is released, the stroking opening 171 of the stroking door 172 opens, and when the lock assembly 20 locks the other end of the stroking door 172, the stroking door 172 is fixed to the observation window 10. Thus, by providing the lock assembly 20, the stroking door 172 can be locked to the observation window 10, and since the lock assembly 20 must be released before the stroking door 172 can be opened, it is possible to prevent the stroking door 172 from being opened by mistake. The lock assembly 20 may be a fastener.

[0087] 25, the lock assembly 20 includes a lock groove 201 and a lock member 202, the lock groove 201 is formed on the stroking door 172, the lock member 202 is arranged to be movable to the observation window 10, and a lock protrusion 203 is arranged on the lock member 202. The engagement between the lock protrusion 203 and the lock groove 201 makes it easy to switch between locking and unlocking of the lock assembly 20, and also increases the contact area and improves the reliability of the installation. When the lock protrusion 203 is fitted into the lock groove 201, the stroking door 172 is fixed to the observation window 10, and when the lock protrusion 203 is separated from the lock groove 201, the stroking door 172 can open the stroking opening 171. For example, at least one of the lock 202 and the lock groove 201 may be made of a deformable material, so that the lock protrusion 203 can move into the lock groove 201 to lock. As shown in FIG. 25, a locking protrusion 2031 is provided on the locking protrusion 203, and the locking protrusion 2031 protrudes in the thickness direction of the locking protrusion 203 to facilitate engagement with the locking groove 201.

[0088] 27, in another embodiment of the present invention, an escape hole 1711 is formed on the stroking door 172, the escape hole 1711 is provided adjacent to the lock groove 201, and when the lock protrusion 203 is separated from the lock groove 201, the lock protrusion 203 faces the escape hole 1711. Thus, when the lock assembly 20 is in the unlocked state, the lock protrusion 203 protrudes from the position of the escape hole 1711, so that the stroking door 172 can rotate inward or outward to open the stroking hole 171.

[0089] 27, the lock groove 201 and the escape hole 1711 may be disposed along the circumferential direction of the stroking door 172, and the lock member 202 is movable along the circumferential direction of the stroking door 172. For example, the lock member 202 can be slidably engaged with the observation window 10 to move smoothly, making it easier for the user to use.

[0090] 25, a baffle 30 is provided on the observation window 10, extending toward the center of the case 1, and the baffle 30 and the observation window 10 form a second mounting groove 301, and the locking member 202 is provided so as to be movable into the second mounting groove 301. The provision of the baffle 30 can prevent pets from accidentally touching the locking member 202, and can switch the open / closed state of the locking member 202, thereby improving the safety of the dryer 100 during use.

[0091] According to an embodiment of the present invention, as shown in FIG. 23, a plurality of engagement segments 173 are provided at intervals along the circumferential direction of the smooth door 172 on one side of the edge of the opening 17 in the thickness direction, and each engagement segment 173 forms a fitting groove 174 at an interval with the edge of the opening 17, and an attachment hole 175 is formed between two adjacent engagement segments 173. A plurality of flange segments 101 are provided at intervals along the circumferential direction of the smooth door 172 on the outer peripheral edge of the observation window 10. The plurality of flange segments 101 pass through the corresponding attachment holes 175 and are fitted into the corresponding fitting grooves 174 by rotating with respect to the opening 17. This allows the case 1 and the observation window 10 to be detachably connected, allowing efficient attachment and detachment. This installation allows the observation window 10 to be detachable by rotating it, and also makes it easy to position it. For example, some of the multiple flange segments 101 can pass through corresponding mounting holes 175 and rotate relative to the opening 17 to fit within corresponding fitting grooves 174 .

[0092] Further, as shown in FIG. 22 and FIG. 23, a first stopper protrusion 1731 is provided at one circumferential end of at least one engagement segment 173, and a second stopper protrusion 102 is provided at one circumferential end of at least one flange segment 101. The second stopper protrusion 102 engages with the first stopper protrusion 1731 to limit the rotation of the stroking door 172 relative to the opening 17, and when removing the flange segment 101, when the flange segment 101 is fitted into the corresponding fitting grooves 174, the first stopper protrusion 1731 abuts against the second stopper protrusion 102 to prevent further rotation of the stroking door 172 relative to the case 1. By providing two stopper protrusions, the accuracy of installation is improved and positioning is facilitated. For example, one end of the flange segment 101 may be fitted into the corresponding fitting groove 174, and the second stopper protrusion 102 may be provided at the other end of the flange segment 101.

[0093] In the embodiment of the present invention, as shown in FIG. 2, FIG. 21, FIG. 9 and FIG. 23, a limit groove 18 is formed on the case 1, and a second limit block 103 is provided on the observation window 10. When the flange segment 101 is engaged with the fitting groove 174, the second limit block 103 is engaged with the limit groove 18, and the cat-stroking door 172 rotates with respect to the opening 17. The second stopper 103 provided on the observation window 10 can be engaged with the limit groove 18 and inserted into the limit groove 18 as the observation window 10 rotates. The engagement of the second limit block 103 with the limit groove 18 makes positioning easier, and the observation window 10 is more stably fixed to the case 1, making it less likely to be destroyed by a pet in the case 1. For example, the limit groove 18 and the second limit block 103 may be located at the upper end of the dryer 100, which can further reduce the possibility of being destroyed by a pet. For example, the notch in the limit groove 18 opens toward the second limit block 103, and when the user applies a large force, the second limit block 103 is pushed into the limit groove 18 along the circumferential direction of the observation window 10, thereby fixing the second limit block 103 and the limit groove 18.

[0094] For example, an example in which the inner surface of the case 1 faces the outer surface of the case 1 during installation will be described. When the installation of the observation window 10 begins, the flange segments 101 are located at the corresponding installation openings 175, and the observation window 10 is rotated counterclockwise so that the flange segments 101 can be fitted into the corresponding fitting grooves 174, so that the first limiting block 7 can be deformed to enter the limit groove 18 and return to its initial state, and the first limiting block 7 and the second limiting block 103 are relatively fixed to each other due to the restriction of the side wall of the limit groove 18. When removing the observation window 10, a clockwise acting force is applied to rotate the observation window 10, and the second limiting block 103 is removed from the limit groove 18. At this time, the observation window 10 can rotate along the circumferential direction of the opening 17, and when the flange segments 101 are completely separated from the fitting grooves 174 and are at the position of the corresponding installation openings 175, the observation window 10 can be removed from the case 1 and taken out. When the first stopper projection 1731 and the second stopper projection 102 come into contact with each other, the observation window 10 cannot rotate.

[0095] According to an embodiment of the present invention, at least one air vent 1712 is formed through the wall forming the drying chamber 11. For example, as shown in Figs. 4, 20, 22 and 23, the pet door 172 is formed with a plurality of air vents 1712, which facilitates ventilation and ventilation inside the case 1 of the dryer 100, so that pets inside the case 1 can breathe fresh air and feel comfortable. The air vent 1712 may be formed in the door 8. In addition, a nameplate may be provided on the observation window 10, and contents such as letters and images may be engraved on the nameplate, thereby enabling various designs of the dryer 100 to be realized.

[0096] In another embodiment of the present invention, as shown in Figures 1 and 3, two petting openings 171 are formed on the left and right walls of the case 1, respectively. There are two petting doors 172, and the two petting doors 172 are provided on the two petting openings 171, respectively, to open and close the corresponding petting openings 171. This makes it easier for the user to monitor the pet, and the user can monitor and pet the pet from multiple angles, improving usability.

[0097] According to an embodiment of the present invention, as shown in Figures 5 to 8, a mounting slot 19 is formed in the case 1, and the aroma box 40 is detachably mounted in the mounting slot 19 by a magnetic assembly. This allows the aroma box 40 and the mounting slot 19 to be easily attached and detached with a simple connection method. The aroma box 40 has a first mounting method and a second mounting method in the mounting slot 19, and at least one through hole 4015 is formed in the aroma box 19. When the aroma box 40 adopts the first mounting method, the interior of the aroma box 410 does not communicate with the interior of the case 1, and when the aroma box 40 adopts the second mounting method, the interior of the aroma box 40 communicates with the interior of the case 1 through the through hole 4015.

[0098] As shown in Figs. 7 and 8, when it is necessary to remove an unpleasant odor in the dryer 100, the aroma box 40 can be attached in the arrangement slot 19 of the case 1. In this case, the aroma box 2 adopts the second installation method, and the aroma box 2 can effectively diffuse the aroma through the through holes 215 to remove the unpleasant odor in the dryer 100. In addition, the aroma box 40 can be firmly fixed on the case 1. As shown in Figs. 5 and 6, when it is not necessary to remove an unpleasant odor from the dryer 100, the aroma box 40 can be installed in the arrangement slot 19 in the first installation method. In this case, the aroma box 40 is stably installed in the arrangement slot 19 while preventing the aroma in the aroma box 40 from diffusing into the case 1, and the displacement or loss of the aroma box 40 can be avoided. Furthermore, when the aroma of the aroma box 40 becomes weak, the aroma box 40 can be simply removed from the arrangement slot 19 and replaced with a new aroma box 40.

[0099] According to an embodiment of the present invention, a through hole 4015 is formed on one side surface of the aroma box 40. When the aroma box 40 is in the first mounting mode, the inner wall of the arrangement slot 19 closes the through hole 4015. When the aroma box 40 is in the second mounting mode, the through hole 4015 is located on the open side of the arrangement slot 19. As shown in FIG. 5, the aroma box 40 has a slightly rectangular shape, and the through hole 4015 may be formed on the upper or lower surface of the aroma box 40, or may be formed on four surfaces in the circumferential direction of the aroma box 40. When removing odors from the dryer 100, the surface of the through hole 4015 provided in the aroma box 40 faces the open side of the arrangement slot 19, and the aroma in the aroma box 40 can be dissipated into the case 1 through the through hole 4015. When there is no need to remove unpleasant odors from the dryer 100, the surface of the through hole 4015 provided in the aroma box 40 can be moved away from the open side of the arrangement slot 19. In this case, the through hole 4015 can be closed facing the open side inner wall of the arrangement slot 19 to prevent the aroma from escaping from inside the aroma box 40.

[0100] In another embodiment of the present invention, a seal 60 is provided on the inner wall of the arrangement slot 19, and when the aroma box 40 is in the first installation mode, the seal 60 closes the through-hole 4015. As shown in Figures 6 and 8, the seal 60 is provided on the ceiling wall in the arrangement slot 19, and when the aroma box 40 is in the first installation mode, the seal 60 closes the through-hole 4015. When the aroma box 40 does not need to release aroma, the seal 60 can be used to close the through-hole 4015 to stop the aroma box 40 from emitting aroma.

[0101] In addition, the seal 60 is a silica gel pad, but is not limited thereto. The material of the silica gel pad is soft and can be deformed to a certain extent, so that it can be in close contact with the inner wall of the arrangement slot 19 to close the through hole 4015, thereby ensuring the sealing between the seal 60 and the through hole 4015.

[0102] According to an embodiment of the present invention, the magnetic assembly 50 includes a screw 501 and a magnetic body 502 provided on the aroma box 40, the magnetic body 502 is provided on the aroma box 40, and the magnetic body 502 magnetically engages with the screw 501 to removably install the aroma box 40 in the arrangement slot 19. As shown in FIG. 5 to FIG. 8, the magnetic body 502 is installed in the arrangement slot 19 of the case 1 at a position corresponding to the screw 501 of the aroma box 40. Thus, the aroma box 40 and the case 1 are removably connected through the screw 501 and the magnetic body 502, and the aroma box 40 and the case 1 are directly connected by a magnetic effect, so that there is no need to use an external tool for installation and removal, and the replacement of the aroma box 40 is more convenient and quicker. For example, the number of screws 501 may be two. Two screws 501 are installed at an interval along the longitudinal direction of upper case 70, and each of the two screws 501 corresponds to two magnetic bodies 502, and each screw 501 can pass through upper case 70 and connect to a screw on the inner wall of case 1, whereby screw 501 is magnetically attracted to magnetic body 502, and at the same time, screw 501 can firmly fix upper case 70 to the inner wall of case 1. Furthermore, since aroma box 40 and case 1 are detachably connected when dryer 100 is moved, there is a risk that aroma box 40 will fall out of case 1, but upper case 70 can protect aroma box 40, making aroma box 40 less likely to fall out of case 1.

[0103] According to a specific embodiment of the present invention, the aroma box 40 includes a case 401 and a cover 402. One side of the case 401 is open, and the cover 402 is provided on the side of the case 401, the cover 402 and the case 401 form a storage space, the magnetic material 502 is provided in the storage space, and a through hole 4015 is formed in the cover 402 and / or the case 401. Here, the through hole 4015 may be formed on one side of the cover 402 and the case 401, or the through hole 4015 may be formed on both the cover 402 and the case 401. As shown in FIG. 29, one side of the case 401 in the thickness direction is open, and the cover 402 faces the open side of the case 401, and the aroma material can be placed in the storage space to diffuse the aroma inside the dryer 100.

[0104] 29, there are a plurality of through holes 4015. The plurality of through holes 4015 are formed at intervals in the bottom wall surface of the case 401, which is the underside of the aroma box 40. When the case 401 of the aroma box 40 in the arrangement slot 19 faces the inside of the case 1 of the dryer 100, the aroma of the aromatic material in the aroma box 40 can be dissipated into the case 1 through the plurality of through holes 4015.

[0105] Furthermore, the inner wall of the case 1 and the upper case 70 form a first mounting chamber 701 and a second mounting chamber 702 that communicate with each other, and the second mounting chamber 702 is located on the rear wall 13 side of the case 1 adjacent to the first mounting chamber 701, and an electric control element 90 and an electric wire are provided in the first mounting chamber 701, one end of the electric wire is connected to the electric control element 90, and the other end of the electric wire extends into the second mounting chamber 702.
