It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
As shown in figure 1, the embodiment provides a filtering and sterilizing structure for a toilet bowl and a squatting pan deodorizing device, and as odor generated during defecation can be diffused to the whole toilet, the device sucks the odor through an overflow pipe and a double-cavity circulating pipe when the odor is generated during the defecation, and then the odor is discharged through the double-cavity circulating pipe to achieve the deodorizing and sterilizing effects. The equipment specifically comprises a machine shell 1, a first fan 2, a second fan and a filter element 3. The filter element 3 is an active carbon filter element 3, and the active carbon filter element 3 has countless fine holes called as capillary tubes. Such "capillary" has a strong adsorption ability, and since the surface area of the carbon particles is large, it can sufficiently contact with impurities, odor, bacteria, etc. in the gas. Impurities, odors, bacteria, etc. in these gases are adsorbed through these "capillaries" and thus perform a purifying function.
Internal structure of the casing 1: the inner cavity of the machine shell 1 comprises an air inlet exchange cavity 4, a filtering front cavity 5, a first mounting cavity 6, a filtering rear cavity 7 and an air outlet exchange cavity 8 which are sequentially communicated. The air inlet exchange cavity 4 is provided with an air inlet, the air outlet exchange cavity 8 is provided with an air outlet, and the first fan 2 is arranged in the air inlet exchange cavity 4, so that air is sucked into the air inlet exchange cavity 4 from the air inlet and is exhausted to the filtering front cavity 5; and the second fan is arranged in the air outlet exchange cavity 8 and used for sucking the air of the filtered cavity 7 into the air outlet exchange cavity 8 and discharging the air from the air outlet. In addition, a second installation cavity communicated with the air inlet exchange cavity 4 is arranged between the air inlet and the air inlet exchange cavity, and the device also comprises a negative ion generator 9 and an ozone generator 10 which are arranged in the second installation cavity. The filter element 3 is installed in the first installation cavity 6 and is used for deodorizing and sterilizing gas flowing through the pre-filtering cavity 5 and the post-filtering cavity 7.
The air filtering principle of the equipment is as follows: odor generated in toilet use enters from the air inlet, sequentially passes through the second mounting cavity, the air inlet exchange cavity 4, the filtering front cavity 5, the first mounting cavity 6, the filtering rear cavity 7 and the air outlet exchange cavity 8, is discharged into the water tank from the air outlet, and finally is released into air in the toilet after passing through water in the water tank. Therefore, the air can be mixed with the negative ions generated by the negative ion generator 9 in the second mounting cavity by the ozone generated by the ozone generator 10, and then passes through the active carbon filter element 3 together to remove most of odor in the air, and meanwhile, the filter element 3 and the ozone carry out sterilization treatment on the air and the water in the water tank, so that the number of bacteria in the air is reduced while deodorization is carried out, and the deodorization and sterilization effects are improved.
In addition, because the purifying effect of the active carbon filter element 3 can only be kept for a period of time, the filter element 3 needs to be replaced regularly to keep good deodorizing and sterilizing effects, the filter element 3 is arranged in the first mounting cavity 6 in a detachable connection mode, and the difficulty of the replacement process can be greatly reduced by detaching the active carbon filter element 3, so that the later maintenance is facilitated. The cover plate can be arranged on the side wall of the first mounting cavity 6, the activated carbon filter element 3 can be replaced after the cover plate is disassembled, and the replacement mode is simple. The first fan 2 and the second fan in the device also have service life and need to be replaced after being damaged, so the air inlet exchange cavity 4 is provided with a detachable first side cover 11, and the air outlet exchange cavity 8 is provided with a detachable second side cover 12. When first fan 2 or second fan go wrong, can change first fan 2 and second fan after first side cover 11 and the 12 splits of second side cover, make the maintenance simpler.
The equipment is mainly used for a deodorizing device, and the specific installation method comprises the following steps: the casing 1 can be hung on the wall surface of a toilet and can also be fixed on other planes. The machine shell 1 is connected with the double-cavity circulating pipe, an air inlet is communicated with an air inlet cavity channel of the double-cavity circulating pipe, and an air outlet is communicated with an air outlet cavity channel of the double-cavity circulating pipe. The air inlet channel is communicated with an overflow pipe of the water tank, and odor generated by defecation is sucked into the machine shell 1 through the overflow pipe. The air outlet channel is communicated to the water tank, namely filtered air is communicated to the water tank and carries out sterilization treatment on water in the water tank. Other modeling structures may exist in the toilet, and the double-cavity circulating pipe is not necessarily in a vertical state when being installed, and an angle deviation of 15-25 degrees may exist. To overcome the above mounting problem, the apparatus further comprises a direction regulator 13 rotatably mounted to the outside of the housing 1. The direction regulator 13 is disc-shaped and is rotationally connected with the machine shell 1, the direction regulator 13 is provided with two through holes 14, the two through holes 14 are respectively in one-to-one correspondence with the air inlet and the air outlet, and the direction regulator 13 is connected with the double-cavity circulating pipe and is used for adjusting the angle of the double-cavity circulating pipe in the vertical direction, so that the installation is convenient.
