Embodiments of the present application will be described in detail below with reference to the accompanying drawings. Features of the embodiments described below may be combined with each other without conflict.

As shown in fig. 1-3, the present application discloses a discharging device 10, wherein the discharging device 10 has a power input interface 15, and the power input interface 15 is connected to a charging socket of a new energy automobile through an adapter wire 18, so that the discharging device 10 obtains power support. The discharging device 10 is further provided with a plurality of power supply interfaces 11, and a user can insert electric equipment into the discharging device 10 to obtain power support.

It should be noted that, when the discharging device 10 is needed to supply power to other electric devices, the electric power input interface 15 of the discharging device 10 is required to be connected with the charging socket of the new energy automobile to obtain the electric energy in the battery of the new energy automobile, and the electric energy is converted and transferred to the power supply interface 11 to supply power to the electric devices (such as an induction cooker, a mobile phone, a projector and a sound) plugged in the power supply interface 11. In other words, the discharge device 10 cannot perform power storage, and only functions as power transmission and conversion. Of course, in other embodiments, the discharging device 10 may also have an energy storage battery inside, and the new energy automobile may utilize the electric energy stored in the battery to supply power to the energy storage battery. When the discharging equipment 10 is used for supplying power to other electric equipment, the discharging equipment 10 and a new energy automobile can be separated, and then the electric equipment is inserted into the power supply interface 11 of the discharging equipment 10, and an energy storage battery in the discharging equipment 10 provides power support for the electric equipment.

As shown in connection with fig. 2-4, the discharge device 10 further comprises a housing 12, electronic components and a fan. The electronics and fan are located inside the housing 12. Electronic components are used to process electrical signals (e.g., store, convert, etc., electrical power as described above). The fan rotates to drive the air to flow, so that the temperature of the electronic component is reduced, and the normal operation of the electronic component is ensured.

The shell 12 is provided with a through heat dissipation opening 13 and an air outlet 17, and under the drive of a fan, external air can enter the shell 12 through the heat dissipation opening 13 to exchange heat with an electronic component or a space around the electronic component, and then flows out of the shell 12 through the air outlet 17. The heat dissipation port 13 is an air intake port.

In the present application, the number of the heat dissipation ports 13 is two, and the two heat dissipation ports 13 are provided on both sides of the housing 12 along the first direction X. The fans are arranged between the two heat dissipation openings 13, so that the air at the two sides of the shell 12 can enter the interior of the shell 12 to dissipate heat under the driving of the same fans. Of course, in other embodiments, the number of the heat dissipation ports 13 may be three or more, and it is only necessary to ensure that at least two heat dissipation ports 13 are disposed on two sides of the housing 12 along the first direction X, and a better ventilation and heat dissipation effect can be ensured. In the present embodiment, the housing 12 includes two first surfaces 14 disposed opposite to each other along the first direction X, and a second surface 16 adjacent to the two first surfaces 14, and the air outlet 17 is disposed on the second surface 16. The direction of the gas flow can be seen in the direction of the arrows in the figure. The power input interface 15 may also be disposed on the second surface 16.

However, when it is in rainy or snowy weather, external rain or snow easily follows the air flow to the inside of the housing 12 through the heat radiation port 13 and affects the normal operation of the electronic components.

In order to solve the above problems, the inventors made the following improvements:

As shown in connection with fig. 1-4, the discharge apparatus 10 of the present application further comprises a tuyere protection device 100. The tuyere protection device 100 is covered on the heat dissipation port 13.

The tuyere protecting device 100 includes a first barrier 110 and a second barrier 120. The first baffle 110 is remote from the center of the housing 12 relative to the second baffle 120. In other words, the first baffle 110 is disposed outside, and the first baffle 110 is disposed inside.

As shown in fig. 4 and 5, the first baffle 110 is provided with a first through hole 111. Outside rainwater may enter the discharge apparatus 10 through the first through hole 111.

As shown in fig. 4 and 6, and as necessary, as shown in fig. 5, the second barrier 120 is aligned with the first barrier 110 along the first direction X. The second baffle 120 includes a body 121 and an inclined body 122, and a second through hole 1211 is formed in the body 121. The second through hole 1211 has an area larger than that of the first through hole 111. One end of the inclined body 122 is fixedly connected to the bottom of the second through hole 1211 along the second direction Y, and the other end of the inclined body 122 extends obliquely upward in a direction away from the first baffle 110. Wherein the first direction X is perpendicular to the second direction Y. In this embodiment, the first direction X is a horizontal direction, and the second direction Y is a vertical direction.

In the above arrangement, the first and second barrier plates 110 and 120 of the tuyere protecting device 100 are provided with the first and second through holes 111 and 1211, respectively, and external gas can be introduced into the inside of the discharge device 10 through the first and second through holes 111 and 1211 in order in the first direction to reduce the internal temperature of the discharge device 10. In this process, the first through hole 111 having a smaller area can effectively prevent impurities having larger particles from entering the discharge apparatus 10 through the tuyere protecting device 100. The second through hole 1211 having a larger area can secure the flow rate of air, and at the same time, the bottom of the second through hole 1211 is provided with the inclined body 122 extending upward, and the inclined body 122 can prevent external rainwater from directly entering the inside of the discharge device 10 through the second through hole 1211 and affecting the electronic devices located inside the discharge device 10. Specifically, when the external rain and snow enters through the first through hole 111 and the second through hole 1211, the external rain and snow will strike the inclined body 122 and fall down along the inclined surface thereof, thereby preventing the external rain and snow from entering the inside of the discharge apparatus 10 (the inside here being the side of the second barrier 120 away from the first barrier 110) through the second through hole 1211. Through the arrangement, when rainy and snowy weather is met, the possibility that external rain and snow enter the shell 12 through the heat dissipation opening 13 along with air flow and influence the normal operation of electronic components can be effectively reduced or avoided, and the normal operation of the discharge device 10 and the safety performance of the discharge device in use are ensured. Meanwhile, the service life of the device is prolonged.

It should be noted that, the area of the second through holes 1211 is larger than that of the first through holes 111, and it should be understood that the area of any one second through hole 1211 is larger than that of any one first through hole 111, and the sum of the areas of all the second through holes 1211 is larger than that of all the first through holes 111.

In the present embodiment, the number of the second through holes 1211 is two on a horizontal section. By controlling the number of the second through holes 1211, it is possible to prevent the air intake amount from being affected by the relatively small area of the second through holes 1211, and to prevent the structural strength of the second plate body from being affected by the excessively large area of the second through holes 1211.

As described above, the number of the heat dissipation ports 13 may be plural. In the present embodiment, the number of the heat dissipation ports 13 is two, the heat dissipation ports 13 are disposed on two first surfaces opposite to each other along the first direction, and each heat dissipation port 13 is covered with the tuyere protection device 100. In addition, in order to further enhance the waterproof performance of the discharge apparatus 10, the air outlet may also be covered with the air outlet protection device 100.

As shown in the figure, the inventors studied the inclination angle of the inclined body 122 in order to further improve the waterproof performance. Specifically, the inventor found that the plane in which the inclined body 122 is located forms an included angle α with the second direction Y, and when the angle α is too small, the inclination degree of the inclined body 122 is too large, which results in that the shielding range of the inclined body 122 to the second through hole 1211 is too large, so that the air inlet amount entering the discharge device 10 through the second through hole 1211 is limited, and the heat dissipation effect is affected. When the angle α is too small, the inclination of the inclined body 122 is too small, so that the rainwater or snow falling down to the top cannot slide down to the side of the second baffle 120 near the first baffle 110 due to the action of gravity, and thus the better waterproof effect cannot be achieved, and the working stability of the discharge device 10 is further affected.

The inventor finds through a great number of experiments that when the included angle alpha is greater than or equal to 30 degrees and less than or equal to 60 degrees, the problems can be balanced well, and not only the air inlet quantity of the second through hole 1211 can be ensured, but also a good waterproof effect can be ensured, so that the working stability of the discharge equipment 10 is ensured, and the service life of the whole machine is prolonged better. In this embodiment, the included angle α is 45 °, and of course, in other embodiments, the included angle α may be 40 °, 50 °, 55 °, and the like.

As shown in fig. 6, the width of the orthographic projection of the inclined body 122 on the first baffle plate 110 is equal to or greater than the width of the orthographic projection of the second through hole 1211 on the first baffle plate 110. The width referred to herein is the dimension of the inclined body 122 in the third direction W. The third direction W, the first direction X and the second direction Y are perpendicular to each other. Through the above arrangement, it is ensured that the inclined body 122 can receive as much as possible the rain and snow entering the inside of the discharge apparatus 10 through the second through hole 1211, and the part of the rain and snow can drop onto the surface of the inclined body 122, and due to the inclined body 122 having a certain inclination angle, the rain and snow dropped onto the surface thereof moves along the surface thereof in a direction away from the inside of the discharge apparatus 10, and drops into the gap between the first baffle 110 and the second baffle 120, thereby avoiding further inward entering directly through the second through hole 1211.

Further, the front projection of the inclined body 122 on the first baffle 110 may cover the front projection of the second through hole 1211 on the first baffle 110. Through the arrangement, rain and snow entering through the second through hole 1211 can be better blocked, and the waterproof performance is better improved, so that the working stability of the discharging equipment 10 is ensured, and the service life of the whole machine is prolonged.

In the present embodiment, the inclined body 122 and the body 121 are tear-molded, and the second through hole 1211 is formed. In other words, the second baffle 120 is initially a complete plate structure, and then the part of the structure is punched by the punching process, so that the part of the structure is displaced and separated from other parts that are not displaced, and finally the second through hole 1211 is formed. The portion that is pressed and displaced is referred to as an inclined body 122, and the portion that is not displaced is referred to as a body 121.

In the above manner, the second barrier 120 can be obtained by a simple process arrangement at low process cost. At this time, although it is not sufficient that the orthographic projection of the inclined body 122 on the first baffle plate 110 covers the orthographic projection of the second through hole 1211 on the first baffle plate 110, it is sufficient that the orthographic projection of the inclined body 122 on the first baffle plate 110 has a width equal to the orthographic projection of the second through hole 1211 on the first baffle plate 110. In addition, external rainwater cannot directly enter the second through hole 1211 along the horizontal direction, a certain included angle is formed between the external rainwater and the horizontal direction, so that an included angle alpha between the external rainwater and the second direction is more than or equal to 30 degrees, and the inclined body 122 with the included angle alpha less than or equal to 60 degrees can block most of rain and snow entering from the outside.

As shown in fig. 4 to 8, the body 121 of the second barrier 120 is recessed away from the first barrier 110 and forms a receiving chamber 123, and the first barrier 110 covers an opening 124 of the receiving chamber 123. The tuyere protection device 100 further comprises an acoustic insulation cotton 130, and the acoustic insulation cotton 130 is arranged in the accommodating cavity 123.

In the above arrangement, by adding the soundproof cotton 130 between the first baffle 110 and the second baffle 120, the soundproof cotton 130 can absorb noise generated by the operation of the internal parts (such as the rotation of the fan) of the discharging device 10, thereby improving the feeling of use of the user. Meanwhile, the waterproof performance of the discharge device 10 is further improved by the effect of blocking rain and snow entering from the outside through the first through hole 111, so that the discharge device 10 can adapt to more use scenes. Meanwhile, the soundproof cotton can be used for blocking small particle impurities entering the discharge equipment 10 through the first through hole 111, so that the small particle impurities are prevented from further entering a space for accommodating other electronic parts in the discharge equipment 10, the working stability of the discharge equipment 10 is ensured, and the service life of the discharge equipment is prolonged.

Further, the receiving cavity 123 includes a bottom wall 1231. At least a portion of the bottom wall 1231 is inclined downward (as shown with reference to fig. 7) in a direction from the second barrier 120 toward the first barrier 110. Through the above arrangement, the rain and snow that has entered through the first through hole 111 and dropped onto the inclined body 122 and the body 121, after sliding down the body 121 and the inclined body 122 to the bottom wall 1231, moves in a direction away from the second barrier 120 due to the inclination of the bottom wall 1231, further prevents the rain and snow from further entering into the inside of the second barrier 120 through the second through hole 1211, and affects the operation of the electronic components located in the discharge apparatus 10.

In the present embodiment, one end of the bottom wall 1231 adjacent to the first barrier 110 is spaced apart from the first barrier 110, and a drain port 125 is formed, the drain port 125 being for connecting the accommodation chamber 123 and the outside (see fig. 7). When rainwater enters the gap between the first and second baffles 110 and 120 through the first through holes 111 and drops to the inclined body 122 and the rain and snow on the body 121, it may slide down the body 121 and the inclined body 122 to the bottom wall 1231. Due to the inclination of the bottom wall 1231, the rain and snow will move downward along the bottom wall 1231 in a direction approaching the drain port 125, and finally be discharged to the outside through the drain port 125. With the above arrangement, it is possible to prevent the accumulation of the rain and snow in the accommodation chamber 123, and after accumulation to a certain height, enter the space for accommodating the electronic device of the discharge device 10 through the second through hole 1211. The structure is simple, and the process cost is low.

Of course, in other embodiments, a through water leakage hole may be formed in the bottom wall 1231, and two ends of the water leakage hole are respectively connected to the accommodating cavity 123 and the outside, so that the rain and snow in the accommodating cavity 123 can be far away from the accommodating cavity 123 through the water leakage hole.

From the above, it is proved by a lot of experiments that the protection level of the whole machine of the discharging device 10 can be improved to IP53.

Referring to fig. 9, in the actual installation process, the second baffle 120 may be placed on the heat dissipation port 13 of the housing 12. Then, the soundproof cotton 130 is placed in the receiving chamber 123 of the second barrier 120. Then, the first barrier 110 is fixed to the opening 124 of the receiving chamber 123, and the first barrier 110, the second barrier 120, and the housing 12 are fixedly coupled using bolts. At this time, not only the first baffle 110 and the second baffle 120 are fixedly connected to the housing, but also the soundproof cotton 130 is fixedly interposed between the first baffle 110 and the second baffle 120. By the above arrangement, the tuyere protection device 100 is fixed to the heat radiation port 13. Of course, in other embodiments, the parts of the tuyere protecting device 100 may be fixedly connected to form a whole, and then the tuyere protecting device 100 may be fixed to the casing 12. Alternatively, the second baffle 120 may be directly fixed to the housing 12, and then the soundproof cotton 130 and the first baffle 110 may be sequentially installed.

The present application is not limited to the above-mentioned embodiments, but is not limited to the above-mentioned embodiments, and any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical matters of the present application can be made by those skilled in the art without departing from the scope of the present application.
