Abstract
Description
Technical Field
[0001] This utility model relates to the field of air purification technology, and in particular to a purification box for the release of chlorine dioxide gas. Background Technology
[0002] Chlorine dioxide disinfectant tablets have bactericidal, bleaching, and deodorizing effects, but due to their strong corrosiveness, they pose a risk of damage to people or furniture and appliances during household disinfection. Therefore, there is an urgent need for a purification box for the release of chlorine dioxide gas. Utility Model Content
[0003] This utility model specifically provides a purification box for the release of chlorine dioxide gas.
[0004] The purification box for chlorine dioxide gas release provided by this utility model includes a box body (3) and a first box cover (2); the first box cover (2) is provided with multiple sets of first through holes (21).
[0005] Preferably, the box body (3) and the first box cover (2) are elliptical or circular when closed.
[0006] Preferably, one end of the box body (3) is hinged to one end of the first box cover (2), and the other end is movably connected.
[0007] Preferably, the purification box for chlorine dioxide gas release provided by this utility model further includes a second box cover (1); the structure of the second box cover (1) is the same as the structure of the first box cover (2).
[0008] Preferably, the second lid (1) is located on the side of the first lid (2) away from the box body (3); one end of the second lid (1) is hinged to one end of the first lid (2), and the other end is movably connected.
[0009] Preferably, the second box cover (1) is provided with a plurality of second through holes (11) evenly; the number and density of the second through holes (11) are less than the number and density of the first through holes (21).
[0010] Preferably, when the second lid (1) is closed onto the first lid (2), there is a gap between the two.
[0011] Preferably, the bottom of the box has a cross-section.
[0012] The purification box for chlorine dioxide gas release provided by this utility model has a simple structure. The disinfection tablet (4) is isolated from the environment by the box body (3) and the box cover, thereby protecting the environment and preventing damage to people, furniture or clothing. Attached Figure Description
[0013] Figure 1 This is a cross-sectional structural diagram of the purification box for chlorine dioxide gas release provided by this utility model. Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0015] like Figure 1 As shown, the purification box for chlorine dioxide gas release provided in this embodiment includes a box body 3 and a first lid 2; the first lid 2 is provided with multiple sets of first through holes 21. Those skilled in the art will understand that the box body 3 is used to hold chlorine dioxide disinfectant tablets 4. The disinfectant tablets 4 deliquesce naturally, and the volatilized chlorine dioxide gas is released into the environment through the first through holes 21 on the first lid 2, thus disinfecting the air. The purification box for chlorine dioxide gas release provided in this embodiment has a simple structure. The box body 3 and lid isolate the disinfectant tablets 4 from the environment, thereby protecting the environment and preventing damage to people, furniture, or clothing.
[0016] Furthermore, the box body 3 and the first box cover 2 are elliptical or circular when closed.
[0017] Furthermore, one end of the box body 3 is hinged to one end of the first box cover 2, and the other end is movably connected.
[0018] Furthermore, the purification box for chlorine dioxide gas release provided in this embodiment also includes a second box cover 1; the structure of the second box cover 1 is the same as the structure of the first box cover 2.
[0019] Furthermore, the second lid 1 is located on the side of the first lid 2 away from the box body 3; one end of the second lid 1 is hinged to one end of the first lid 2, and the other end is movably connected.
[0020] Furthermore, the second lid 1 is evenly provided with multiple sets of second through holes 11; the number and density of the second through holes 11 are less than the number and density of the first through holes 21. Those skilled in the art will understand that when a small space needs to be disinfected and purified slowly for a long time, the second lid 1 can be closed.
[0021] Furthermore, when the second lid 1 is closed onto the first lid 2, there is a gap between them. Those skilled in the art will understand that a gap is left between the first lid and the second lid when they are closed to ensure airflow.
[0022] Furthermore, the bottom of the box has a cross-section (not shown in the figure). Those skilled in the art will understand that this ensures its stability and guarantees that the gas evaporates upwards.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
