Description

Technical Field

[0001] The utility model relates to the technical field of protective devices for fine chemical feeding, in particular to a dust-proof mask for powder solid feeding. Background Art

[0002] In the field of fine chemicals, it is often necessary to add a variety of raw materials into a mixing and stirring tank to mix the reaction raw materials for subsequent processing. This process requires manual care, and there is a possibility of dust diffusion when adding raw materials. At this time, inhaling dust will cause discomfort to people, so a dust-proof mask is needed.

[0003] When using a dust-proof mask, since the exhaled gas of the human body contains water vapor, the accumulation of this water vapor will produce water droplets. The water droplets will randomly combine into large water droplets and flow, which is extremely easy to flow onto the human face, causing discomfort to the human body, and there are certain deficiencies.

[0004] Therefore, a dust-proof mask for powder solid feeding is provided to solve the above-mentioned problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Embodiment 1:

[0026] Refer to Figures 1 - 3, a dust-proof mask for feeding powdered solids, including a mask body 1, further comprising: multiple groups of liquid guiding grooves 2, arranged inside the mask body 1, and the liquid guiding grooves 2 are used to guide the condensed water droplets inside the mask to flow; a liquid collecting pipe 105, arranged at the bottom of the mask body 1, and the bottom of the liquid guiding groove 2 is located inside the liquid collecting pipe 105; a water absorbing block 4, arranged inside the liquid collecting pipe 105, and the water absorbing block 4 is used to absorb the water collected in the liquid collecting pipe 105; a tightening cap 1051, threadedly connected to the liquid collecting pipe 105, and the tightening cap 1051 is used to seal the liquid collecting pipe 105. An air inlet 101 is arranged on the mask body 1, a filter element 102 is connected inside the air inlet 101, and a locking ring 103 is threadedly connected to the air inlet 101, and the locking ring 103 is used to lock the filter element 102.

[0027] The liquid guiding grooves 2 in this device are equivalent to opening a groove inside the mask. Multiple groups should be set, and the lowest ends all converge in the liquid collecting pipe 105. Only two groups are shown in the figure.

[0028] When in use, the staff wears the mask body 1 on the mouth through an elastic rope to filter dust. Subsequently, when working, the addition of solid raw materials will generate some dust. At this time, the filter element 102 can filter this dust to avoid directly inhaling it into the body.

[0029] After using for a period of time, some water vapor will be generated inside the mask. These water vapor will gather together to form water droplets. These water droplets will flow along the liquid guiding grooves 2 and transfer to the lowest liquid collecting pipe 105. Without the liquid guiding grooves 2, these water droplets will naturally gather together and then flow downward. At this time, these water droplets will flow randomly and cannot be controlled.

[0030] After use, the tightening cap 1051 can be removed, the water absorbing block 4 can be taken out, dried naturally and then installed or replaced with a new one for the next use. The water absorbing block 4 can be a sponge.

[0031] Embodiment 2:

[0032] Refer to Figures 1 - 4 , a dust-proof mask for feeding powdered solids, is basically the same as Embodiment 1. Further, a side air pipe 104 is connected to the mask body 1, a fan 3 is connected inside the side air pipe 104, an installation cover 1041 is connected to the side air pipe 104, a battery compartment 1042 is arranged inside the side air pipe 104, and the battery compartment 1042 is used to supply power to the fan 3. Vent holes 1043 are arranged on both the side air pipe 104 and the installation cover 1041, and filter sponges are arranged inside the vent holes 1043.

[0033] With the setting of the fan 3, if it works for a long time, the temperature inside the face mask will rise rapidly. Especially in summer, it will cause discomfort to people. At this time, one of the groups of fans 3 can be started and the other group can be turned off. The battery in the battery compartment 1042 supplies power to the fan 3, thereby generating suction, enabling some gas to enter through the ventilation holes 1043. These gases will be filtered by the filter sponge, and through the airflow generated by the fan 3, the inside of the face mask can be cooled to a certain extent. These airflows will be discharged through the filter element 102, the other group of side air pipes 104, and the fitting part between the face mask and the human face.

[0034] With the setting of the liquid guiding groove 2 in the present utility model, the condensed water droplets can be guided to flow into the liquid collecting pipe 105 at the bottom, reducing the possibility of the liquid flowing onto the human face and facilitating long-term use.

[0035] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
