Detailed Description

The embodiments described below are only a part of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, 4 and 5, the present embodiment provides a chemical dosing device, which is placed in a filter element 1 for disinfecting water filtered by the filter element 1, wherein the filter element 1 is connected to a circulating pump, and the circulating pump is started to control water to enter the filter element 1. Wherein, the doser include: a housing 2 and a tablet cartridge 3; the casing 2 includes a shell 21, one can dismantle the setting and is in top cap 22 and one on shell 21 top can dismantle the setting and be in the bottom 23 of shell 21 bottom, top cap 22 with bottom 23 sets up relatively, wherein, shell 21 top cap 22 with the space that bottom 23 surrounds does hold chamber 24, be provided with a water inlet 221 on the top cap 22, be provided with a delivery port 231 and a water control assembly 232 on the bottom 23, wherein, bottom 23 with shell 21 threaded connection still is provided with a sealed pad 29 between the two, makes bottom 23 with the better fastening of shell 21 connects.

With reference to fig. 2 and fig. 6, the water outlet control assembly 232 is configured to control the opening or closing of the water outlet 231, when the water flow direction in the filter cartridge 1 is consistent with the water flow direction in the accommodating chamber 24, and the water in the filter cartridge 1 flows from the water inlet 221 to the water outlet 231, the water outlet 231 is opened; the water outlet 231 is closed when the water flow in the cartridge 1 is stationary. In this embodiment, the water outlet control assembly 232 includes a float 2321 and an umbrella valve 2322, the float 2321 is disposed at an end of the accommodating cavity 24 close to the water outlet 231, the umbrella valve 2322 includes a valve stem 23221 and a valve seat 23222, the valve stem 23221 penetrates through the water outlet 231 and is fixedly connected to the float 2321, and the valve seat 23222 is located outside the accommodating cavity 24 for selectively sealing the water outlet 231. When the water in the filter element 1 flows from the water inlet 221 to the water outlet 231, the water flow pushes the umbrella-shaped valve 2322 to move downwards, so that the water outlet 231 is opened, and the medicament can uniformly act on the water along with the water flow. When the water in the filter element 1 is still, the float 2321 will pull the umbrella valve 2322 to close the water outlet 231, and at this time, the medicine will not overflow.

Referring to fig. 3 and 7, the tablet cylinder 3 is disposed in the accommodating cavity 24, a predetermined number of tablets 4 are disposed in the tablet cylinder 3, and when water enters the water inlet 221, the water contacts the tablets 4 and then flows out through the water outlet 231. In this embodiment, the tablet cartridge 3 includes a cartridge body 31, a filter bottom cover 32, a leak-proof housing 33 and a sealing tape 34, a top and a side wall of the cartridge body 31 are sealed and the cartridge body 31 is a hollow structure, the tablet 4 is placed in the cartridge body 31, the filter bottom cover 32 is detachably connected to an end of the cartridge body 31 far away from the top, wherein, a side of the filter bottom cover 32 is filled with water, and a bottom edge of the filter bottom cover 32 is filled with water. The leak protection shell 33 set up in the filter screen bottom 32 outside, it can with barrel 31 lock, seal when sealing sticky tape 34 is used for the lock barrel 31 with leak protection shell 34. The leakage-proof housing 3 is used for sealing the tablet cartridge when not in use, and preventing the tablets from being affected with moisture and the like.

The side wall of the filter screen bottom cover 32 has a predetermined number of through holes 321 arranged circumferentially, and the height of the through holes 321 from the water inlet 221 side to the water outlet 231 side is smaller than the thickness of one tablet 4. This arrangement allows the tablet cartridge 3 to dispense medication that flushes only the lowermost tablet 4. The tablet barrel 3 is a consumable, and when the tablet 4 is used up, the bottom cover 23 is opened, a new tablet barrel 3 is replaced, and then the tablet barrel is screwed. The user can not directly contact the chlorine tablet, so the device is safer and more convenient.

Referring to fig. 2, the housing 2 further includes an adjusting knob 25 and a flow limiting valve 26, the flow limiting valve 26 is fixedly disposed at the water inlet 221 in the accommodating cavity 24, the adjusting knob 25 is rotatably disposed on the housing 2 near the water inlet 221, and the adjusting knob 25 and the flow limiting valve 26 cooperate to control the water flow of the water inlet 221 to perform a flow limiting function or stop the water inlet 221 from feeding water.

Referring to fig. 10, the adjusting knob 25 includes an adjusting knob seat 251, an adjusting knob nut 252 and an adjusting knob screw 253, one end of the adjusting knob nut 252 is connected to the adjusting knob seat 251, the other end of the adjusting knob nut 252 is connected to the adjusting knob screw 253, and the adjusting knob nut 252 is in threaded connection with the housing 2 near the water inlet 221. And an O-shaped ring 28 is arranged, so that the water inlet has better sealing performance. The flow limiting valve 26 comprises a valve body and a flow adjusting hole formed in the valve body, and the adjusting knob screw 253 is matched with the flow adjusting hole to control the water flow of the water inlet 221 to achieve the effect of limiting the flow or stopping the water inlet.

The casing 2 is close to water inlet 221 one end is followed the outside extension of the direction of casing 2 width has a round of arch 27, arch 27 is used for when the balling gun uses support on the lateral wall of filter core 1, thereby it is sealed filter core 1 is close to water inlet 221 one end.

In this embodiment, the filter element 1 is a melt-blown filter element 1. The tablet 4 is a chlorine tablet.

With reference to fig. 8 and 9, in use, the protrusion 27 abuts against the sidewall of the filter cartridge 1 to seal the end of the filter cartridge 1 close to the water inlet 221. When the circulating pump is started, water in the filter element 1 flows from the water inlet 221 side to the water outlet 231 side, at this time, the water flow pushes the umbrella-shaped valve 2322 to move downwards, so that the water outlet 231 is opened, and the medicament can uniformly act on the water along the water flow. When the circulation pump is closed and the water in the filter element 1 is still, the float 2321 pulls the umbrella valve 2322 to close the water outlet 231, and the medicament cannot overflow. Meanwhile, through the matching of the adjusting knob 25 and the flow limiting valve 26, the water inflow of the water inlet 221 can be adjusted to correspond to different water inflow areas and different water inflow rates, so that different dosage in unit time is caused. When the water inlet flow is large, the medicine can be discharged from the water outlet 231 quickly, otherwise, the medicine can be discharged slowly. The tablet barrel only flushes the tablet at the lowest end, so that quantitative flushing and dosing are realized.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention.
