Abstract: A filter housing is adapted to be assembled with a cap and installed with an O-ring. The filter housing includes a surrounding wall that is formed with a retaining groove for installation of the O-ring therein, and that has a plurality of protrusions. The retaining groove is defined among inner and outer surrounding surfaces and a groove end surface. The protrusions protrude from one of the inner and outer surrounding surfaces toward the other. The one of the inner and outer surrounding surfaces is adapted to be separated from the O-ring when the surrounding wall is separated from the cap, and is adapted to contact the O-ring when the surrounding wall is assembled with the cap and when the O-ring is squeezed by the cap to deform.

Abstract: A connector for a reservoir has a body and a guiding member. A passage is defined through the body and communicates with the reservoir. The guiding member is mounted in the passage and has a post and multiple spiral leaves. Accordingly, a vortex flow will be caused as the fluid passes through the guiding member. This can prevent stagnant areas forming in the fluid, and thus germ-breeding areas are eliminated. In addition, the post will abut against the diaphragm of the reservoir to avoid the diaphragm being pushed into the passage when the water chamber of the reservoir is empty. This can ensure that the fluid can be pumped efficiently into the reservoir, and the useful life of the reservoir is prolonged.
