Direct drinking water purifying equipment

Technical Field

The invention relates to the technical field of drinking water treatment equipment, in particular to direct drinking water purification equipment.

Background

At present, the safety problem of drinking water is more and more paid attention to, and common purification methods of drinking water on the market generally comprise a softening method, a distillation method, a boiling method, a magnetization method, a mineralization method, a sterilization method and the like.

Chinese patent application with publication No. CN115286123a discloses a scale inhibitor dosing device for direct drinking water, including the medicine storage box, the medicine storage box is connected with the cylinder body through first check valve, is fixed with two side branch boards of fore-and-aft symmetry on the cylinder body, sliding fit has first piston and the second piston of mutual symmetry in the cylinder body, and first piston is connected with the second rack through inscribing the post, and the second piston is connected with first rack through the outer sleeve, installs the second driving motor on the side branch board of place ahead, and the output of second driving motor is equipped with the third gear with first rack and second rack meshing respectively. When the second driving motor drives the third gear to rotate, the third gear drives the first rack and the second rack to move in a staggered mode, and then the first piston and the second piston are driven to move in a staggered mode through the inner connecting post and the outer sleeve. When the first piston and the second piston are far away from each other, the air pressure in the cylinder body is weakened and the medicament in the medicament storage box is attracted to enter the cylinder body. When the first piston and the second piston are close to each other, the air pressure in the cylinder body is enhanced and presses the medicament in the cylinder body, and the medicament flows downwards into the rotating shaft through the adapter box and is dispersed in the direct drinking water through the support arm of the rotating shaft, so that the medicament is added in the direct drinking water.

However, the inventors found that the following technical drawbacks exist when implementing the scale inhibitor dosing device for direct drinking water:

the device avoids the process of manually adding the medicament into the direct drinking water, but an operator still needs to control the on-off of the second driving motor to realize the addition of the medicament, and does not liberate both hands, so that the degree of automation still needs to be improved; when the medicament is added each time, the second driving motor needs to be started and operated, and more electric energy is consumed under the friction loss of each transmission part.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

The direct drinking water purifying apparatus of the present invention is described below with reference to fig. 1 to 10.

As shown in fig. 2 to 7, the direct drinking water purifying apparatus of the present invention, in example 1, comprises a cabinet 1, a digestion tube 2, a clean water tank 3, a blocking strip 21, a blocking plate 22 and a liquid passing tube 4. The machine case 1 is provided with a water intake chamber 11, a plurality of water taps 111 are arranged in the water intake chamber 11, a water purifying tank 3 is arranged in the machine case 1 and is connected with a water pipe 5 between the water purifying tank and the water taps 111, and the water pipe 5 is provided with a first water pump. The digestion tube 2 extends vertically and the bottom and the water pipe 5 are communicated, an I-shaped plug 23 is arranged in the digestion tube 2 in an elastic sliding fit mode, the I-shaped plug 23 divides the interior of the digestion tube 2 into an upper cavity 24 and a lower cavity 25, the I-shaped plug 23 comprises two plugs 231 which are vertically spaced apart, a middle cavity 26 is formed between the two plugs 231, a first opening 261 is formed in the peripheral wall of the middle cavity 26, an infusion tube 6 is communicated between the first opening 261 and the water pipe 5, a liquid storage tank 61 for storing medicaments is communicated with the infusion tube 6, a valve element 62 is arranged at the communicating position of the liquid storage tank 61 and the infusion tube 6, the valve element 62 can be opened when liquid in the infusion tube 6 flows, and a first one-way valve 241 is arranged on the top wall of the upper cavity 24. The blocking strip 21 is vertically and slidably arranged in the middle cavity 26 and used for blocking the first opening 261, a second opening 262 is formed in the peripheral wall of the middle cavity 26, an air pipe 27 is communicated between the second opening 262 and the upper cavity 24, the air pipe 27 is provided with a second one-way valve 271, and the blocking plate 22 is vertically and slidably arranged in the middle cavity 26 and used for blocking the second opening 262. The first end of the liquid through pipe 4 is communicated with the middle cavity 26, the second end of the liquid through pipe 4 stretches into the water purifying tank 3 and is provided with a blocking piece 7, a floating piece 31 connected with the blocking piece 7 is arranged in the water purifying tank 3, when the floating piece 31 floats upwards, the blocking piece 7 can be driven to open the liquid through pipe 4, and the blocking plate 22 is connected with the floating piece 31, so that when the floating piece 31 floats upwards, the blocking plate 22 is driven to open the second opening 262.

Normally, the water level in the fresh water tank 3 occupies substantially two thirds of the height of the fresh water tank 3. When one of the faucets 111 is opened to receive water, the first pump pumps the water in the fresh water tank 3 to the faucet 111, however, at the moment when the faucet 111 is opened, a negative water hammer effect is generated in the water pipe 5, and the negative water hammer effect is specifically shown as a sudden decrease of the water pressure in the water pipe 5, so that at the moment, the elastic force acting on the i-shaped plug 23 is larger than the water pressure in the water pipe 5, the elastic force drives the i-shaped plug 23 to move downwards, and the plug body 231 positioned above in the i-shaped plug 23 pushes the plug strip 21 to move downwards, so that the first opening 261 is gradually opened by the plug strip 21. After the water flow in the water pipe 5 is stabilized, the water pressure of the water pipe 5 is restored as before, the i-shaped plug 23 is restored under the action of the water pressure, and at this time, the first opening 261 is no longer blocked by the blocking strip 21 and the plug body 231 positioned above, so that the first opening is completely opened.

Subsequently, the water in the water pipe 5 is poured between the two plug bodies 231 of the i-shaped plug 23 through the infusion pipe 6 and the first opening 261 under the action of the own water pressure, and when the water flows in the infusion pipe 6, the valve member 62 is opened, so that the liquid path between the liquid storage tank 61 and the infusion pipe 6 is conducted, and the medicament in the liquid storage tank 61 enters the infusion pipe 6 and is collected toward the middle cavity 26 by the water in the infusion pipe 6.

In addition, when the i-shaped plug 23 moves downward, the space of the upper chamber 24 increases and the air pressure therein decreases, and the external air is sucked into the upper chamber 24 through the first check valve 241, and when the i-shaped plug 23 moves upward and returns, the space of the upper chamber 24 decreases again, and the first check valve 241 prevents the air in the upper chamber 24 from being discharged, so that the air in the upper chamber 24 can flow into the air tube 27 only through the second check valve 271, thereby increasing the air pressure in the air tube 27. When a cup of water is received and the faucet 111 is closed, a positive water hammer effect is generated inside the water pipe 5, and the positive water hammer effect is specifically shown as a sudden increase of the water pressure in the water pipe 5, so that the water pressure in the water pipe 5 is instantaneously greater than the elastic force acting on the i-plug 23. The hydraulic pressure drives the i-plug 23 to move upwards, the i-plug 23 will continue to compress the space of the upper chamber 24, and the air in the upper chamber 24 will continue to flow into the air pipe 27 through the second check valve 271, further increasing the air pressure in the air pipe 27, at the same time, the upward movement of the i-plug 23 will cause the plug body 231 below to push the plug strip 21 upwards, and then the plug strip 21 moves upwards and re-plugs the first opening 261. After the first opening 261 is closed, the water flow in the infusion tube 6 can not flow into the middle cavity 26 any more, so that the process of delivering the medicament in the liquid storage tank 61 to the middle cavity 26 is stopped, and the quantitative convergence of the medicament in the middle cavity 26 is ensured by the design.

Subsequently, if the operator supplements water into the clean water tank 3, the water level in the clean water tank 3 rises and supports the float member 31 to rise, the rising float member 31 drives the blocking member 7 to open the liquid pipe 4, and simultaneously drives the blocking plate 22 to open the second opening 262, so that air in the air pipe 27 flows into the middle cavity 26 through the second opening 262 and increases the air pressure in the middle cavity 26, and the air pressure increased in the middle cavity 26 directly acts on the agent previously collected in the middle cavity and presses the agent into the liquid pipe 4, and the agent flows into the clean water tank 3 through the second end of the liquid pipe 4, thereby achieving the effect of adding the agent into the clean water tank 3. The added medicament and the added water are quantitative, so that the equal proportion input of the water and the medicament can be realized through the design form of each part, thereby not only ensuring the purification of the newly added water in the water purifying tank 3, but also avoiding the waste caused by excessive medicament addition.

From the above, the water purifying tank 3 in this embodiment can automatically add the medicine while supplementing water, thereby avoiding the process of manually controlling the motor to add the medicine. The addition of the agent in the water purifying tank 3 is realized by utilizing the energy generated by the water hammer effect, so that the consumption of electric energy is avoided, the consumption of secondary energy is reduced, the harmful energy generated by the water hammer effect is converted into useful energy, and the energy is consumed and reused.

It will be appreciated that the water flow in the water pipe 5 will tend to stabilize and the water pressure in the water pipe 5 will gradually return to the original level after the faucet 111 is turned off, and at this time, the i-shaped plug 23 will be pushed to gradually return by the elastic force acting on the i-shaped plug 23.

It will be appreciated that the top wall of the fresh water tank 3 is provided with a first air vent for allowing the interior of the fresh water tank 3 to communicate with the outside atmosphere, ensuring that the air pressure within the fresh water tank 3 is at atmospheric pressure, facilitating the delivery of water from the fresh water tank 3 into the water pipe 5.

It will be appreciated that the stopper rod 21 is vertically slidably mounted to the inner peripheral wall of the central chamber 26 and that there is a frictional force with the inner peripheral wall of the central chamber 26 which is able to overcome the weight of the stopper rod 21 for temporary securement of the stopper rod 21.

Specifically, the i-plug 23 further includes a center post 232 extending in the vertical direction, the center post 232 being located between the two plug bodies 231 and connecting the two plug bodies 231.

The second end of the feed pipe 4 passes through the top wall of the fresh water tank 3.

Specifically, a heating rod is arranged in the water purifying tank 3 and is used for high-temperature sterilization and further purifying the water body in the water purifying tank 3.

Wherein the medicament can be a scale inhibitor or a bacteriostatic agent, etc.

Specifically, three water taps 111 are distributed at equal intervals along the left-right direction, and according to different requirements of people, the three water taps 111 may be divided into a hot water switch, a warm water switch, a cold water switch, etc., and may be other forms, which is not limited in this embodiment.

It will be appreciated that the design of the digestion tube 2 and the i-plug 23 also provides for the buffering of the water hammer effect within the water tube 5, particularly when the faucet 111 is used, the water pressure within the water tube 5 will be reduced, and the i-plug 23 will move down to accommodate the water pressure change in order to avoid collapse of the wall of the water tube 5. When the tap 111 is turned off, the water pressure in the water pipe 5 increases, and the i-plug 23 moves upward to accommodate the change in the water pressure in order to avoid bursting of the pipe wall of the water pipe 5.

With continued reference to fig. 5 and 6, further, the blocking member 7 includes a fixed cylinder 71 and a sleeve 72, the fixed cylinder 71 is provided in the fresh water tank 3 and communicates with the second end of the liquid passing pipe 4, the fixed cylinder 71 extends vertically and a liquid passing hole 711 is provided at the lower portion. The sleeve 72 is slidably sleeved on the fixed cylinder 71 and seals the liquid through hole 711, the sleeve 72 is fixed with a vertically extending friction rod 721, the float member 31 is provided with a through hole and is slidably sleeved on the friction rod 721 through the through hole, the friction rod 721 is in frictional contact with the peripheral wall of the through hole, so that when the float member 31 floats upward, the friction rod 721 and the sleeve 72 are driven to rise by friction force, and the sleeve 72 opens the liquid through hole 711.

When the water in the clean water tank 3 is replenished, the float 31 floats upward with the rising water level, and under the friction force between the float 31 and the friction lever 721, the float 31 drives the friction lever 721 to move upward, the friction lever 721 drives the sleeve 72 to move upward, the sleeve 72 gradually opens the liquid opening 711, and thereby the second end of the liquid passing pipe 4 is opened. The chemical previously collected in the intermediate chamber 26 is allowed to flow into the sleeve 72 through the liquid passage pipe 4 by the air pressure and into the fresh water tank 3 through the liquid passage hole 711 of the sleeve 72, thereby achieving the effect of adding the chemical to the fresh water tank 3.

It will be appreciated that both the upper and lower ends of the fixed cylinder 71 are closed, and the upper end of the fixed cylinder 71 and the second end of the liquid passing tube 4 are fixed together, and the upper end of the fixed cylinder 71 and the second end of the liquid passing tube 4 are communicated with each other.

As can be appreciated, the liquid passage holes 711 are provided in the peripheral wall of the fixed cylinder 71.

The friction lever 721 is provided in two and symmetrical to each other about the axis of the sleeve 72.

Specifically, the inside of the clean water tank 3 is provided with guide tables 32 below the float 31, the guide tables 32 are provided with guide holes which are equal in number and correspond to the friction rods 721 one by one, the guide holes extend vertically, the lower parts of the friction rods 721 are slidably arranged in the corresponding guide holes, and the guide holes are used for guiding the friction rods 721 to slide up and down.

Specifically, the shape of the float 31 may be a block, a cylinder, a column, or the like, and the present embodiment is not limited thereto.

With continued reference to fig. 6, further, a first limiting flange 712 for preventing the sleeve 72 from moving downward is provided at the bottom of the fixed cylinder 71, the sleeve 72 is stopped against the first limiting flange 712, and a second limiting flange 713 for preventing the sleeve 72 from moving upward is provided at the top of the fixed cylinder 71.

When the tap 111 is opened to use water, the water level of the clean water tank 3 is lowered, the float 31 is lowered, and the float 31 drives the friction lever 721 to move downward under the action of friction force between the float 31 and the friction lever 721, and the friction lever 721 drives the sleeve 72 to move downward and return. When the sleeve 72 is stopped against the first limit flange 712, the downward movement of the sleeve 72 is stopped, and there is a continuous lowering of the water level of the fresh water tank 3, so that the float 31 tends to continue to descend with the water level, however, at this time, the friction lever 721 is restrained by the sleeve 72 and cannot continue to move downward, whereby the gravity of the float 31 overcomes the friction between the float 31 and the friction lever 721 and drives the float 31 to continue to move downward with the water level.

In the water replenishing stage of the fresh water tank 3, the float member 31 is moved upward by the frictional lever 721 when floating, and when the sleeve 72 is stopped against the second stopper flange 713, the upward movement of the sleeve 72 is stopped, so that the upward movement of the sleeve 72 is prevented, and the sleeve 72 is prevented from being pulled out of the fixed cylinder 71.

With continued reference to fig. 9 and 10, further, the side wall of the fresh water tank 3 is provided with a through-groove 33 above the float 31 and extending vertically, and a connecting rod 221 passing through the through-groove 33 is connected between the closure plate 22 and the friction lever 721.

When the floating member 31 floats upwards, the friction rod 721 is driven to move upwards, the friction rod 721 drives the connecting rod 221 to move upwards, and the connecting rod 221 drives the blocking plate 22 to move upwards. The upwardly moving closure plate 22 progressively opens the second opening 262 to provide communication between the second opening 262 and the central chamber 26 to facilitate the flow of air from the air tube 27 into the central chamber 26.

It will be appreciated that the through slot 33 is used to pass through the link 221 on the one hand and to give way to the up and down sliding of the link 221 on the other hand.

Specifically, the first end of the link 221 is fixedly connected to one of the friction rods 721, and the second end of the link 221 vertically slides through the peripheral wall of the absorber pipe 2 and is fixedly connected to the closure plate 22.

With continued reference to fig. 3 and 7, in embodiment 2, on the basis of embodiment 1, the direct drinking water purifying apparatus further includes a gas tank 8, the gas pipe 27 includes a gas inlet pipe and a gas outlet pipe 272, the gas tank 8 is communicated with the upper chamber 24 through the gas inlet pipe, the gas tank 8 is communicated with the second opening 262 through the gas outlet pipe 272, and the second check valve 271 is installed in the gas inlet pipe.

In this embodiment, the staff may not supplement water to the clean water tank 3, directly receive water, and take a cup of water each time, or when the tap 111 is turned on and off once, the positive water hammer and the negative water hammer effect will occur once in the water pipe 5, so that the i-shaped plug 23 will slide up and down once, and further drive the blocking strip 21 to open and close the first opening 261 once, and the water flowing in the infusion tube 6 will flow into the middle cavity 26 together with the medicament in the liquid storage tank 61 at the stage of opening the first opening 261. In the case of several water receiving or several opening/closing of the tap 111, the first opening 261 is opened and closed several times, whereby the water and chemicals in the intermediate chamber 26 are accumulated to correspond to the amount of water to be replenished in the fresh water tank 3.

Meanwhile, when the i-plug 23 slides up and down each time, the first check valve 241 draws out the external air once, and the external air is pressed into the air tank 8 through the second check valve 271, so that the air tank 8 realizes temporary storage of the air. In the water receiving or the water tap 111 being opened and closed for several times, the i-shaped plug 23 slides up and down for several times, so that the i-shaped plug 23 continuously extracts the external air and presses the external air into the air tank 8, the air in the air tank 8 is accumulated, the air pressure in the air tank 8 and the medicine amount in the middle cavity 26 are designed to generate a corresponding relation, and when the medicine amount in the middle cavity 26 is larger, the air pressure in the air tank 8 is higher. Then, when the fresh water tank 3 is replenished, since the amount of water flowing out of the fresh water tank 3 is larger, the amount of water to be replenished is larger, and at this time, the float member 31 drives the closure plate 22 to move upward through the connecting rod 221, the closure plate 22 opens the second opening 262, the air tank 8 and the middle chamber 26 are communicated through the air outlet pipe 272, the accumulated air pressure in the air tank 8 acts on the accumulated chemical in the middle chamber 26, and the accumulated chemical is pressed into the fresh water tank 3 through the liquid passing pipe 4, thereby realizing the corresponding purification of the fresh water in the fresh water tank 3.

It is understood that in this embodiment, the addition amount of the chemical, the addition amount of the water and the magnitude of the air pressure acting on the chemical are substantially in correspondence, so that the addition effect of the chemical in the fresh water tank 3 is ensured, and the purification effect of the chemical on the water in the fresh water tank 3 is ensured.

It will be appreciated that the second check valve 271 functions to pass air flowing from the upper chamber 24 to the cylinder 8 and to block air flowing from the cylinder 8 to the upper chamber 24.

With continued reference to fig. 5, 7 and 8, further, the liquid storage tank 61 is located above the liquid delivery tube 6 and has a liquid outlet tube 611 with a rectangular cross-sectional shape, the liquid outlet tube 611 has a first nozzle and a second nozzle which are opposite from each other, the first nozzle is in communication with the liquid storage tank 61, the second nozzle is in communication with the liquid delivery tube 6, the valve member 62 includes a rotary shaft 621 and a baffle 622, and the rotary shaft 621 is located in the liquid outlet tube 611 and rotatably mounted to the second nozzle. The baffles 622 are multiple and spaced circumferentially along the shaft 621, the baffles 622 are connected to the shaft 621, and one part of the baffles 622 extends into the infusion tube 6, and the other part is located in the liquid outlet tube 611 and is used for sealing the second nozzle.

Thus, normally, the medicament in the reservoir 61 cannot enter the infusion tube 6 because the second orifice is closed by the baffle 622.
