[0032] See also Figure 1 , Figure 2 and Figure 5 A battery installation structure of a ventilator includes: a ventilator body 1, a battery 2 and a heat conducting plate 3.

[0033] The ventilator body 1 includes a heating plate 11, a shell 12 and an elastic member 13; the heating plate 11 is arranged in the shell 12 for heating the temperature and humidity tank 4; the elastic member 13 is arranged in the shell 12, one end of the elastic member 13 abuts against the shell 12, and the other end abuts against the heating plate 11, and the shell 12 is provided with an installation cavity 121; the battery 2 is installed in the installation cavity 121; the heat conducting plate 3 is installed in the shell 12, and the heat conducting plate 3 is located below the battery 2. When the temperature and humidity tank 4 is removed, the heating plate 11 is in contact with the heating plate 11 under the action of the elastic member 13, and the heat conducting plate 3 contacts the heating plate 11. The heat energy in the heating plate 11 is transferred to the heat conducting plate 3 through contact heat conduction, and the heat conducting plate 3 radiates heat to the battery 2; when the temperature and humidity tank 4 is placed on the heating plate 11, the heat conducting plate 3 is separated from the heating plate 11.

[0034] Specifically, the temperature and humidity tank 4 filled with liquid is placed in the heating plate 11. Under the gravity of the liquid and the temperature and humidity tank 4, the elastic member 13 is pressed down, the heating plate 11 is not in contact with the heat conducting plate 3, and the power supply is started to heat the temperature and humidity tank 4. After the ventilator completes the work, the temperature and humidity tank 4 is removed, and the heating plate 11 is in contact with the heat conducting plate 3 under the action of the elastic member 13, and the heat conducting plate 3 heats and dries the battery 2. Preferably, the model of the battery 2 is U80510, and the elastic member 13 is a spring.

[0035] A battery installation structure for a ventilator of the present invention can use the residual heat energy after heating in a temperature and humidity tank 4 to dry the battery 2 and its environment through a heat conducting plate 3 installed in an installation cavity 121. The battery 2 is placed in a relatively dry environment, which not only realizes the reuse of the residual heat after the ventilator is working and accelerates the heat dissipation of the heating plate 11 to prevent people from being burned by accidental touch; but also provides a dry environment for the battery 2 to prevent the battery 2 from getting damp and causing accidents during use, thereby increasing the service life of the battery 2.

[0036] See also Figure 5 Furthermore, the heating plate 11 is provided with a plurality of groups of magnets 111, and the plurality of groups of magnets 111 are evenly spaced along the circumference of the heating plate 11; the heat conducting plate 3 is at least partially made of iron material, and can be connected to the heating plate 11 by magnetic adsorption. The magnetic force is less than the weight of the temperature and humidity tank 4, ensuring that after the temperature and humidity tank 4 is placed on the heating plate 11, the heating plate 11 is not interfered by the magnetic force and works normally. The magnets 111 are provided to make the heating plate 11 in closer contact with the heat conducting plate 3, which can fully conduct heat and can still work normally when the elastic member 13 partially fails.

[0037] See also Figure 1 and Figure 4 Furthermore, the mounting cavity 121 is provided with a mounting groove 122 connected thereto, and the battery 2 is mounted in the mounting groove 122. The battery 2 is mounted in the mounting groove 122, which is isolated from other components of the ventilator, thereby enhancing the safety of the battery 2. Specifically, when the housing 12 is placed normally, the mounting groove 122 extends upward. Preferably, the top of the mounting groove 122 is an arc groove. In case of rainy weather, water vapor condenses and flows down along the arc groove and the inner wall of the mounting groove 122.

[0038] See also Figure 4 Furthermore, the heat conducting plate 3 is provided with a first extension portion 31, and the first extension portion 31 extends into the mounting groove 122. Specifically, the first extension portion 31 surrounds the battery 2 from the circumference, and can evenly dry the battery 2 and the inner wall of the mounting groove 122.

[0039] See also Figure 1 , Figure 3 and Figure 4Furthermore, the ventilator body 1 also includes a power circuit assembly board 14, which is installed in the installation cavity 121, and the battery 2 is electrically connected to the power circuit assembly board 14. Specifically, the power circuit assembly board 14 is spaced apart from the battery 2, and the power circuit assembly board 14 is provided with a circuit switching device of the prior art. When the ventilator cannot be connected to an external power source, the circuit switching device can respond quickly and connect the battery 23 to the ventilator power supply system, which can ensure the operation of the ventilator and avoid accidents caused by the ventilator being unable to work due to lack of power. Preferably, the ventilator body 1 also includes a display screen 15, which displays the power status of the battery 2 on the display screen, so that the user can clearly know the remaining power and remaining usage time of the battery 2, which is convenient for the user to charge the battery 2 in time.

[0040] See also Figure 1 and Figure 4 Furthermore, the heat conducting plate 3 is provided with a second extension portion 32, and the second extension portion 32 is located below the power circuit assembly board 14. Specifically, the first extension portion 31 and the second extension portion 32 are integrally formed, and the shape of the second extension portion 32 matches the power circuit assembly board 14. When the power circuit assembly board 14 is working, the electronic components of the power circuit assembly board 14 generate heat, and the heat generated is radiated to the second extension portion 32, and then to the first extension portion 31, and the first extension portion 31 dries the storage battery 2 and the mounting groove 122 from the circumferential direction.

[0041] See also Figure 2 and Figure 3 Furthermore, the ventilator body 1 also includes a fan 16, and the housing 12 is provided with an air inlet slot 17 that cooperates with the fan 16, and the air inlet slot 17 is connected to the installation cavity 121. Specifically, the installation cavity 121 is provided with a plurality of sets of ventilation slots 123 on the opposite side of the air inlet slot 17, and the installation cavity 121 is connected to the installation slot 122. When the fan 16 is working, the fan 16 uses the principle of air flow to suck the outside air into the fan 16 through the air inlet slot 17, and after the fan 16 is accelerated and turned, the air is discharged into the installation cavity 121 and then into the installation slot 122. In this way, the air circulates and the battery 2 is in a ventilated environment.

[0042] See also Figure 4 Furthermore, first hole grooves 124 are oppositely arranged on both sides of the mounting groove 122 along the length direction, the first hole grooves 124 are connected with other cavities of the shell 12, and the other cavities are connected with the air inlet groove 17 through the ventilation hole grooves 123, and the battery 2 is further in an air circulation environment.

[0043] See also Figure 7Furthermore, the shell 12 also includes a plurality of groups of elastic clips 18, the elastic clips 18 are fixedly installed in the shell 12, and the battery 2 is installed in the elastic clips 18. Specifically, the elastic clips 18 are installed on the edge of the mounting groove 122, and the clip cavity 181 of the elastic clip 18 faces the mounting groove 122. The inner diameter of the clip cavity opening is smaller than the thickness of the battery 2. During installation, the clip cavity opening is opened by hand or tools, and the battery 2 is installed inside. With this structure, after the battery 2 is installed, the battery 2 is suspended in the mounting groove 122, and is tightly attached to the inner wall of the elastic clip 18 under the action of gravity. The installation is stable, and the suspension structure enables all sides of the battery 2 to be located in an environment with airflow. This structure replaces the conventional battery 2 installed flatly in the shell 12, avoiding the close contact area from being easily affected by moisture, and preventing it from being difficult to dry after being affected by moisture.

[0044] See also Figure 7 Furthermore, the ventilator body further includes a bottom cover 19, and a second hole 191 is provided on the surface of the bottom cover 19, and the second hole 191 is connected to the installation cavity 121. The second hole 191 is installed in the bottom cover 19, not only the battery 2 is further placed in an environment with good air circulation; but also the ventilator is placed on the workbench through a thin foot pad, dust is not easy to enter the installation groove 122, and the battery 2 is relatively clean.

[0045] The battery installation structure of a ventilator of the present invention can heat the residual heat energy after the temperature and humidity tank 4 is heated, and the electronic components of the power circuit assembly board 14 are heated. The battery 2 and its environment are dried by the heat-conducting plate 3 installed in the installation cavity 121. The battery 2 is placed in a relatively dry environment, which not only realizes the reuse of the residual heat during and after the operation of the ventilator, but also accelerates the heat dissipation of the heating plate 11 to prevent people from being burned by accidentally touching it, and accelerates the heat dissipation of the power circuit assembly board 14 to improve the service life of the ventilator; and provides a dry environment for the battery 2 to prevent accidents caused by moisture when the battery 2 is used. The fan 16, each hole groove, the installation cavity 121, the installation groove 122 and the elastic clip 18 are arranged to form a suspension structure to provide a ventilated environment for the battery 2, and the bottom cover 19 is arranged on the ventilator body to provide a clean environment for the battery 2.
