Ventilation and heat sink for mobile toilets

This creation is about a ventilation and heat sink for mobile toilets. More specifically, it uses the chimney effect, the principle of heat convection, the heat flow is formed in the mobile toilet, the heat flows upwards, and several vents are opened under the mobile toilet. Naturally, the air is introduced into the mobile toilet, and the hot air and odor in the mobile toilet are circulated upwards to the exhaust vent, and a large amount of hot air and odor are discharged, which is used for cooling and cooling in the mobile toilet and a large amount of natural convection air, and The rain-proof device blocks the ventilation and heat dissipation device of the flowing toilet of the incoming rainwater.

As far as I know, because of the large number of people involved in large-scale outdoor activities, and often outdoor activities, it is necessary to use mobile toilets to provide a large number of people to go to the toilet, so mobile toilets become necessary temporary facilities for large-scale outdoor activities. It plays an important role. The mobile toilet is usually closed for privacy, so as to avoid the leakage of spring light, so it is easy to cause stinking. The smell of entering the mobile toilet is unbearable, and the mobile toilets are mostly FRP. Made of alloy steel plate and plastic steel plate, it is not easy to dissipate heat when exposed to sunlight, which affects the temperature inside the mobile toilet and raises the temperature inside the mobile toilet. It is like an oven, and when it is used in the hot summer, it is also sweaty.

Although some operators use a foamed material to insulate the inner wall of the mobile toilet to block the heat source, or install a grid plate on the periphery to ventilate it, but it cannot discharge odor and hot air, so it exhausts and dissipates heat. The effect is very limited.

As shown in the first, second and third figures, the conventional mobile toilet 10 has a base 11 And a main body 12, the base 11 has a toilet and the like, the main body 12 is a rectangular box, the water pipe and the water collecting, flushing and hand washing equipment can be assembled therein, and a plurality of grooves 111 are formed in the base 11. The groove 111 is for airflow, and the main body 12 and the base 11 are hollow. There are multiple walls, and the airflow is naturally convected by the hot air. The airflow enters the hollow space 112 in the multi-layer wall from the groove 111 of the base 11 (second drawing). Then, the space inside the main body 12 is entered, and the hot air and the odor are discharged from the upper grid plate 121 of the main body 12, but the air entering the hollow space 112 in the multi-layer wall by the groove 111 is small, and the hollow space 112 in the multi-layer wall It is narrow and has very little air entering, and the effect of convective air exhaustion is not good.

Furthermore, as shown in the fourth figure, a manufacturer installs a ventilation device 21 on the top of the mobile toilet 20, and uses the electric energy of the battery or the solar energy 22 to pump the odor in the mobile toilet 20. However, the battery needs to be charged in advance, and the power has time. Sex, has its life, and increases costs. Although solar power generation is a natural energy source, no electricity is generated in case of cloudy or rainy days.

As shown in the fifth figure, if a manufacturer installs a turbofan impeller 31 on the top of the mobile toilet 30, it is also necessary to use the electric power to draw air, and it is also inconvenient to have a generator to supply electric power.

The traditional mobile toilets are closed, heat-dissipating, or poorly ventilated, unable to discharge hot air and odors, causing the temperature in the mobile toilet to rise, and the people in the toilets can't bear the odor and high temperature.

In view of this, the inventor of the present invention is still actively developing, researching and improving, and accumulating years of manufacturing and production experience based on the above drawbacks, and finally has an invention capable of solving the above drawbacks.

The present invention provides a ventilation and heat dissipation device for a mobile toilet, which comprises a base and a main body. The base is connected under the main body, and the total height after the base and the main body are joined is set at about the lower half of the total height. a venting opening, at a predetermined position above the main body, an air outlet, an air outlet and a rainproof device; accordingly, the chimney effect is used, and the lower vent is used Naturally, the air is introduced into the mobile toilet, and the hot air and odor in the mobile toilet are circulated upward to the exhaust vent, and the hot air and the odor are discharged in a large amount, and the cooling in the mobile toilet and a large amount of natural convection are caused by the rain-proof device. Block the incoming rain.

The present invention aims to provide a ventilation and heat dissipation device for a mobile toilet. The main purpose is to provide a chimney effect and a principle of heat convection. The heat flow forms a heat flow in the mobile toilet, and several vents are opened under the mobile toilet to naturally introduce air to the flow.

Ventilation and heat sink for the mobile toilet that enters the rainwater.

The present invention provides a ventilation and heat dissipation device for a mobile toilet. The other purpose is to provide an inverted V-shaped roof, which circulates hot air and odor in the mobile toilet to the exhaust vent, and then has an exhaust vent and a flow port. Type, a large amount of hot air and odor are discharged, and the rainwater from the roof of the rain-proof device blocks the rainwater from flowing out through the drain hole.

The present invention provides a ventilation and heat dissipation device for a mobile toilet. The second purpose is to provide a circular arc roof, which circulates the hot air and odor in the mobile toilet to the exhaust vent, and then has an S-shaped air outlet and a circulation port. The hot air and the odor are discharged in a large amount, and the rainwater from the roof of the rainproof device is blocked, so that the rainwater flows out through the drain hole.

The present invention provides a ventilation and heat dissipation device for a mobile toilet. The other purpose is to provide a window on the side of the main body, that is, an air outlet, and a top cover and a diagonal plate outside the top cover, using the chimney effect, the principle of heat convection, The heat flow is formed in the main body, and the heat flows upwards, so that the lower vent is introduced into the mobile toilet, and the hot air and the odor in the mobile toilet are circulated upward to the exhaust vent (window), and then the secondary vent, a large amount of The hot air and odor are discharged, which is used for cooling and a large amount of natural convection in the mobile toilet. The rainwater from the top of the roof of the rain-proof device blocks the rainwater from flowing out through the drain hole to prevent rainwater from entering.
