The through hole is located directly below the turntable 23. The bottom of the shell 1 is provided with a footing 11.

Example 2

In the embodiment, the water containing mechanism in embodiment 1 is used, referring to fig. 1 to 4, a water quality detector comprises a housing 1, a motor 21 is arranged at the bottom of the housing 1, the motor 21 is connected to a rotating disc 23 through a connecting part 22, a plurality of cup holders 24 for fixing detection cups are arranged on the rotating disc 23, a rotating disc annular part 31 is arranged at the lower side of the rotating disc 23 close to the periphery, a housing annular part 32 is arranged at the bottom of the housing 1 and outside the motor 21, the rotating disc annular part 31 and the housing annular part 32 are arranged in a staggered manner, wherein a water retaining strip 12 is arranged at the front side of the bottom of the housing.

The housing annular portion and the turntable annular portion are shown in cross-section. The staggered arrangement mode is that the height of the lower end of the annular part of the rotating disc is smaller than that of the upper end of the annular part of the shell. After the liquid splashing prevention device is arranged alternately, the splashed liquid cannot splash into the interior and is blocked by the staggered protection components. Meanwhile, the annular part of the shell has a height, and can play a role in isolating liquid accumulated at the bottom of the shell. The water retaining strip can block liquid at the bottom of the shell and enclose the bottom area of the shell without overflowing.

The arrangement of the water bar is shown in fig. 2, and the motor and other parts at the bottom of the shell are omitted, and the motor and other parts are arranged at the bottom of the shell and are positioned in the area behind the water bar. In addition, the height of the water bar in the drawings is only an example, and the height of the water bar can be increased as required to improve the liquid accumulation capacity, and particularly, the height of the shell annular part 32 is larger than that of the water bar 12 to improve the safety.

The bottom of the shell 1 is arranged in the shell annular part 32, an air outlet is formed in the shell annular part, an air inlet is formed in the side wall of the shell 1, an air pipe 62 is arranged in an installation cavity in the bottom of the shell, an inlet of the air pipe 62 is connected with the air inlet, an outlet of the air pipe 62 is connected with the air outlet, and a fan 61 used for blowing external air into the shell annular part is arranged on the air pipe 62.

Inside the air of fan in with the environment blows in to discharge from the clearance department of carousel annular portion and casing annular portion, can dispel the heat to the motor that surrounds, do benefit to motor work, improve life.

Set up in the installation cavity and hold water mechanism, it has and holds water box 4 to hold water mechanism, it sets up fluid-discharge tube 41 to hold 4 downside of water box, set up the valve on the fluid-

discharge tube

41, 1 bottom of casing sets up the through-hole that runs through to holding in the water box, it sets up floater 51 in the water box 4 to hold, floater 51 top sets up lifter 53, lifter 53 middle part sets up vertical mouth of a river 53a of crossing, lifter 53 installs in through-hole department, and lifter 53 can be in through-hole department activity from top to bottom, set up flowing back mark 53b on the lifter 53, on the floater 51 and lie in the lifter 53 both sides and set up gag lever post 52 respectively, upward float when the floater, the gag lever post supports casing bottom downside, the flowing back mark is located casing.

It should be noted that the bottom of the housing (the bottom side wall of the housing) should have a certain thickness to facilitate the movement of the lifting rod at the through hole. The drainage marks may be strips with a luminescent coating or a more distinctive color (e.g., red) on the surface for easy viewing.

After the casing bottom has liquid, flow to holding the water box from the vertical mouth of a river of crossing of lifter, when holding in the water box liquid accumulation more back, the floater drives the lifter and rises under liquid buoyancy, when the gag lever post supports casing bottom downside, flowing back mark casing bottom top (the top of lateral wall at the bottom of the casing to convenient looking over), see this mark after appearing when operating personnel, should in time flowing back.

The through hole is located directly below the turntable 23. Is beneficial to use. When the lifting rod rises to the limit position, the top of the lifting rod does not contact with the turntable, and the lifting rod and the turntable do not affect each other.

The bottom of the shell 1 is provided with a footing 11. The four base feet are respectively arranged at four corners of the bottom of the shell. The footing bed hedgehopping device improves the convenience of use.
