[0002] The lower pipe of the drain outlet at the bottom of the kitchen sink is water-sealed, and the water used for sealing is clean tap water. Although there is a water seal as a barrier, if the gas pressure in the pipe network is relatively high, a small amount of gas can escape and affect the indoor air environment. Especially for sinks in the kitchen environment, various food and oil stains can easily cause pipe blockage. When the climate is warm, food residues remaining in the pipe are easy to rot and deteriorate, emitting a disgusting odor, affecting the indoor environment.

[0003] In order to solve the above problems, there are drains on the market that use elastic sealing plates or magnetic sealing plates to prevent odor, but they are all integrated into the drain head and cannot be removed separately. Sometimes users want a larger drainage volume, and the drain head products on the market cannot be selected and installed according to the needs of consumers, causing inconvenience in use.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0031] like Figures 1 to 6 As shown, it is a kind of deodorizing sink drain head involved in the utility model, including a drain shell 1 and a deodorizing core 2 which is detachably arranged in the drain shell 1, the deodorizing core 2 including an upper cylinder 21, a lower sealing plate 22 and a reset mechanism; a connecting seat 211 is formed in the middle of the upper cylinder 21, and a plurality of ribs 212 for connecting the connecting seat 211 and the upper cylinder 21 are also provided in the upper cylinder 21; the lower sealing plate 22 is slidably connected relative to the upper cylinder 21 along the axial direction, and the lower sealing plate 22 has a blocking position and an opening position for respectively blocking and opening the lower opening of the upper cylinder 21; the reset mechanism resets the lower sealing plate 22 to the blocking position when water is not discharged; the upper cylinder 21 of the deodorizing core 2 is detachably connected to the inner wall of the drain shell 1 through a thread.

[0032] In this way, the utility model relates to a water tank deodorizing drain head, wherein the deodorizing core 2 can be selectively installed in the drain housing 1 through threads as needed. The deodorizing core 2 is installed when deodorizing is needed, and the deodorizing core 2 is removed when a large drainage flow rate needs to be prioritized. Preferably, the upper cylinder 21 is provided with an external thread 213 on the outside, and the drain housing 1 is provided with an internal thread 11, and the external thread 213 on the upper cylinder 21 is threadedly connected with the internal thread 11 of the drain housing 1.
