Description

Technical Field

[0001] The present application relates to the technical field of pet electrical appliances, and in particular to a pet hair dryer. Background Art

[0002] At present, keeping pets has become common, and pets need to be bathed to ensure their hygiene. Some pets with thick and long hair are difficult to dry naturally after bathing, so they usually need to use a hair dryer with heating function to dry the pet's hair, and pet hair dryers came into being.

[0003] Pet hair dryers use the airflow generated by a high-power motor and cooperate with heating equipment to help pets quickly dry their hair. Pet hair dryers have high power when blowing, so a large amount of heat energy will be released during the operation of the circuit board. To ensure that the circuit board has sufficient heat dissipation, most existing circuit boards are directly installed in the air duct on the side of the air inlet, and the heat is taken away by the operation of the airflow. However, due to the high wind speed and strong wind force on the air inlet side, high requirements are placed on the installation stability of the circuit board, further increasing the production cost. In the blowing process, the air flow in the air inlet duct has a high wind speed, and the environment is relatively humid during the drying process of pet hair. The moisture in the environment carried by the air inlet airflow is high, which makes the moisture content of the air flow higher. For a long time, the safety performance of the circuit board is easily affected, thereby affecting the service life of the pet hair dryer. Utility Model Content

[0023] The embodiment of the present application provides a pet hair dryer, which is used to solve the high installation stability requirements of existing circuit boards, further increasing the production cost. During the blowing process, the airflow in the main air duct on the air inlet side has a high wind speed and carries a lot of moisture in the environment, resulting in a high moisture content in the airflow, which can easily affect the safety performance of the circuit board for a long time, thereby affecting the service life of the pet hair dryer.

[0024] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] See also Figures 1 to 6The embodiment of the present application provides a pet hair dryer, including a housing 100, a fan 200, an air inlet 300 and a circuit board 400; the fan 200 and the air inlet 300 are both installed inside the housing 100, and the air inlet 300 is located on the air inlet side of the fan 200; an air guide port 310 is provided at one end of the air inlet 300, and the air guide port 310 forms a sealed connection with the air inlet end of the fan 200; the air inlet 300 is provided with a partition wall 320 surrounding the air guide port 310, and the inner cavity of the partition wall 320 forms an air inlet channel , the air inlet channel is connected to the air inlet port 110 of the shell 100; a mounting groove 330 is formed on one side of the air inlet member 300 outside the partition wall 320, and the circuit board 400 is located in the mounting groove 330; the partition wall 320 is a closed surface at the surface corresponding to the mounting groove 330, and a connecting hole 321 connected to the mounting groove 330 is formed on the surface away from the closed surface; when the fan 200 is running, the airflow enters the fan 200 from the air inlet channel, and the airflow of the mounting groove 330 flows through the connecting hole 321 and enters the air inlet channel.

[0026] Specifically, the air inlet side of the housing 100 is an opening to form an air inlet 110, the air inlet member 300 is installed on the side close to the air inlet 110, and the other end of the air inlet member 300 is an air guide port 310. A sealing ring is provided between the air guide port 310 and the air inlet end of the fan 200 of the housing 100 to form a sealed connection to ensure that the airflow is input into the fan 200 from the air inlet channel; a partition wall 320 is provided on the side of the air inlet member 300 close to the air guide port 310 to separate the air flow from the fan 200. The partition wall 320 is surrounded by an air guide port 310, so that the air inlet member 300 forms an air inlet channel in the inner cavity of the partition wall 320 and docks with the air inlet port 110; one side wall of the air inlet member 300 extends outward to form a mounting groove 330 on the outside of the partition wall 320, and the side of the partition wall 320 corresponding to the mounting groove 330 is a closed surface, and a plurality of connecting holes 321 are opened on the other two sides relative to the closed surface, and the connecting holes 321 connect the mounting groove 330 with the air inlet channel 110. The shape of the mounting groove 330 corresponds to the shape of the circuit board 400. The circuit board 400 is fixed in the housing 100 and is located in the mounting groove 330. When the fan 200 is in operation, the inner cavity of the partition wall 320 is the main air duct. The airflow of the fan 200 mainly flows directly from the air inlet 110 through the inner cavity of the partition wall 320 into the fan 200. The airflow velocity and flow rate of the air inlet channel are both relatively large. Since the fan 200 has suction force and there are gaps in the housing 100, part of the airflow flows through the mounting groove 330 through the connecting hole 321 into the air inlet channel under the action of suction force. When the airflow is in operation, the heat of the circuit board 400 in the mounting groove 330 can be taken away, thereby dissipating the heat for the circuit board 400. The airflow and flow rate in the mounting groove 330 are relatively small, and the stability requirements of the circuit board 400 are relatively low, and it is not easily affected by the airflow. At the same time, due to the low moisture content, the circuit board 400 is not easily affected by moisture, and the safety performance can be guaranteed.

[0027] Further, the circuit board 400 is fixed to the side wall of the housing 100, and the side wall of the air inlet 300 abuts against the inner wall of the housing 100, so that the mounting groove 330 encloses the circuit board 400. The housing 100 is provided with a fixed threaded column inside, and the circuit board 400 is fixed to the housing 100 by a threaded connector such as a screw or a stud. The shape of the mounting groove 330 is adapted to the circuit board 400. When the air inlet 300 is installed in the inner cavity of the housing 100, the inner wall of the housing 100 is provided with a limiting wall abutting against the side wall of the mounting groove 330, thereby enclosing the circuit board 400. The mounting and fixing method of the circuit board 400 is simple, and does not require a large number of fixed structures, which effectively reduces the production cost. By cooperating with the mounting groove 330, the airflow flowing through the mounting groove 330 by the fan 200 running in the fan 200 takes away the heat, and the heat is effectively dissipated.

[0028] See also Figures 2 to 4The partition wall 320 is annular, and there is a gap between the side wall of the partition wall 320 with the connecting hole 321 and the side wall of the air inlet member 300 to form an air guide cavity 340. The partition wall 320 provided on the inner wall of the air inlet member 300 is annular, corresponding to the annular side wall of the air inlet member 300 away from the mounting groove 330, thereby forming an annular inner cavity; the side wall of the partition wall 320 corresponding to the mounting groove 330 is a closed surface, and the side walls of the adjacent mounting grooves 330 are provided with a plurality of connecting holes 321. There is a certain gap between the air inlet member 300 and the partition wall 320 on both sides of the corresponding connecting hole 321, thereby forming an air guide cavity 340, so that the airflow in the mounting groove 330 can flow smoothly to the connecting hole 321.

[0029] Furthermore, the air inlet member 300 forms an air guide groove 350 on a side close to the air inlet 110, and the size of the air guide groove 350 is larger than the size of the partition wall 320 to form a step surface 351. The step surface 351 is provided with an air supply hole 352, and the air supply hole 352 is connected with the air guide cavity 340. The air guide groove 350 provided on the side of the air inlet member 300 away from the air guide cavity 310 is connected with the air inlet 110, and the diameter of the air guide groove 350 is larger than the diameter of the partition wall 320, and then a step surface 351 is formed at the bottom of the air guide groove 350, and the step surface 351 corresponds to the position of the air guide cavity 340. The air guide groove 350 and the air guide cavity are connected by opening a plurality of air supply holes 352. When the fan 200 is running, part of the air flow can enter the installation groove 330 from the air inlet 110 through the air supply hole 352. To ensure that the airflow generated in the mounting slot 330 has a certain flow rate, the air guide cavity 340 is provided with a wind shield 341 near the air supply hole 352. The wind shield 341 shields the air supply hole 352 in the horizontal direction. When the airflow enters from the air inlet 110, it is shielded by the wind shield 341 and the flow path trajectory is changed, thereby increasing the airflow, ensuring that the airflow can flow through the circuit board 400 and then enter the air guide cavity 340, so as to take away the heat of the circuit board 400.

[0030] See also Figure 6The air guide groove 350 is provided with an air guide assembly 500, and the air guide assembly 500 is rotatably clamped to the air inlet 110. The air guide assembly 500 includes an air guide cover 510, an air guide sleeve 520 and an air guide frame 530; the air guide cover 510 is clamped to the air inlet 110; the side wall of the air guide frame 530 is provided with a ventilation hole 531; when the fan 200 is running, the air flow flows into the air guide sleeve 520 through the air guide cover 510, and enters the inner cavity of the partition wall 320 through the ventilation hole 531. The air guide assembly 500 is integrally rotated and snap-fitted into the air inlet 110, and can be quickly disassembled and assembled for cleaning; wherein, the side wall of the air guide cover 510 is provided with an L-shaped slot, and the inner wall of the air inlet 110 is provided with a block, and after the air guide cover 510 is rotated, the block is snap-fitted into the slot, thereby fixing the entire air guide assembly 500 at the air inlet 110; the end surface of the air guide cover 510 is provided with a plurality of holes for air intake, and a handle is provided in the middle for easy opening of the cover; the side wall of the air guide frame 530 is snap-fitted with the side wall of the air guide cover 510, and the air guide sleeve 520 is located between the air guide cover 510 and the air guide frame 530 under the limit of the air guide frame 530; the side wall of the air guide sleeve 520 is arc-shaped, and the opening at one end close to the inner side is narrowed, so that air is drawn in The airflow is rectified, and the opening is connected with the ventilation hole 531 opened on the side wall of the air guide frame 530, and the airflow is input into the inner cavity of the partition wall 320 through the ventilation hole 531; a filter element 600 is installed in the gap between the air guide sleeve 520 and the air guide frame 530. In this embodiment, the filter element 600 is preferably a filter sponge, which filters the airflow entering the air inlet channel before entering the inner cavity of the partition wall 320; a sound-absorbing cotton block is also installed between the air guide cover 510 and the air guide sleeve 520 to absorb sound and reduce noise; by cooperating with the air guide component 500 in the air guide groove 350 of the air inlet member 300, the airflow entering the fan 200 is rectified, filtered and reduced in noise, thereby improving the quality of the pet hair dryer.
