Abstract

A portable toilet odor blocking device includes a container, a foaming liquid, a liquefied gas and a spraying module. The container is formed with an accommodation space. The foaming liquid is accommodated in the accommodation space. The liquefied gas is accommodated in the accommodation space. The spraying module is mounted to the container and configured to use air pressure of the liquefied gas to spray the foaming liquid to a water surface of a toilet, bowl and to selectively spray the foaming liquid to a wall surface of the toilet bowl, such that foam formed by the foaming liquid is configured to completely cover the water surface of the toilet bowl and selectively cover the wall surface of the toilet bowl. Wherein, the foam formed by the foaming liquid is configured to block an odor from excrement above or under the water surface of the toilet bowl.

Claims

1. A portable toilet odor blocking device, comprising:

a container formed with an accommodation space;

a foaming liquid accommodated in the accommodation space;

a liquefied gas accommodated in the accommodation space; and

a spraying module mounted to the container and configured to use air pressure of the liquefied gas to spray the foaming liquid to a water surface of a toilet bowl and to selectively spray the foaming liquid to a wall surface of the toilet bowl, such that foam formed by the foaming liquid is configured to completely cover the water surface of the toilet bowl and selectively cover the wall surface of the toilet bowl;

wherein the foam formed by the foaming liquid is configured to block an odor of excrement above or under the water surface of the toilet bowl.

2. The portable toilet odor blocking device of claim 1, wherein the foaming liquid comprises a surfactant configured to generate foam.

3. The portable toilet odor blocking device of claim 2, wherein the foaming liquid further comprises a fragrant agent configured to be distributed in the air.

4. The portable toilet odor blocking device of claim 2, wherein the foaming liquid further comprises a deodorant configured to be distributed in the air for eliminating the odor of excrement.

5. The portable toilet odor blocking device of claim 1, wherein the foaming liquid is not corrosive.

6. A toilet odor blocking method, comprising:

providing a portable container, wherein the portable container is filled with a foaming liquid and a liquefied gas;

holding and moving the portable container to use air pressure of the liquefied gas to spray the foaming liquid to a water surface of a toilet bowl and to selectively spray the foaming liquid to a wall surface of the toilet bowl, such that foam formed by the foaming liquid is configured to completely cover the water surface of the toilet bowl and selectively cover the wall surface of the toilet bowl; and

the foam formed by the foaming liquid blocking an odor from excrement above or under the water surface of the toilet bowl.

7. The toilet odor blocking method of claim 6, wherein the foaming liquid is sprayed to the toilet bowl before a user excreting to the toilet.

8. The toilet odor blocking method of claim 6, wherein the foaming liquid comprises a surfactant, and a fragrant agent, and the portable toilet odor blocking method further comprises distributing the fragrant agent in the air during spraying the foaming liquid.

9. The toilet odor blocking method of claim 6, wherein the foaming liquid comprises a surfactant and a deodorant, and the portable toilet odor blocking method further comprises distributing the deodorant in the air to eliminate the odor of excrement in the air during spraying the foaming liquid.

10. The toilet odor blocking method of claim 6, wherein the foaming liquid is not corrosive.
