Abstract: The utility model relates to a household submersible pump, which comprises a pump base, a pump body and a signal light assembly, wherein the pump base is provided with a water outlet, a water inlet and a first filter screen; the pump body has an inner housing having an inner electrical chamber equipped with a circuit board therein and a front mount, and an outer housing having a front guiding seat; the signal light assembly comprises a signal light connected to the circuit board and a light guiding column with a waterproof seal ring embedded therein; the light guiding column is able to be rotated from a first state in which it can be inserted into the front mount through the front guiding seat to a second state in which it is locked in the front mount, and is set to be able to export the light emitted from the signal light to the outside of the outer housing. The utility model not only achieves an outward propagation of light to indicate the status of the pump but also achieves an IPX8 level waterproof.

Abstract: The present disclosure provides an intelligent explosion-proof table, including a worktable, an explosion-proof box; the worktable has a window passing through in the vertical direction. The explosion-proof box with an open top is arranged under the window of the worktable. A lifting plate which can be moved up and down and a support mechanism for driving the lifting plate to be lifted are provided inside the explosion-proof box. The lifting plate is used for placing a danger source and matches with the window and is capable of being raised into the window.

Abstract: The present application discloses a speed-adjustable automatic limiting sausage stuffer. The sausage stuffer includes a rack and photoelectric sensors. A first limiting sensing hole is disposed on the top end of the rack, a second limiting sensing hole is disposed on the middle of the rack, and a perpendicular distance between the first limiting sensing hole and the second limiting sensing hole is a height of a barrel. The photoelectric sensors are disposed symmetrically on two sides of the rack, and when the first limiting sensing hole or the second limiting sensing hole on the rack is located on a same plane as the photoelectric sensors, the symmetrically disposed photoelectric sensors and the first limiting sensing hole or the second limiting sensing hole lie on a single straight line.

Abstract: The present application discloses a heat preservation box and a split-type wooden box with a heat preservation box that includes a heat preservation box and a wooden box. The heat preservation box is placed in the wooden box and they are flexibly connected to each other. The heat preservation box may be taken out of the wooden box for separate use. There is no connection between the wooden box cover and a body of the wooden box; a drain plug on a side surface of the heat preservation box is used in cooperation with a side cover plate of the wooden box, so that waste water in the heat preservation box can be prevented from entering the wooden box; the box body of the heat preservation box is locked with the upper cover of the heat preservation box, and the operation is simple.
