Description

Technical Field

[0001] The utility model relates to the technical field of space purification equipment, in particular to an atomization device for space purification. Background Technique

[0002] In public places, such as vehicles, personnel, farms, factories, sewage treatment plants, garbage stations, etc., spray disinfection and sterilization devices can play an important role. Especially in the disinfection and epidemic prevention channels in public areas and indoor spray disinfection schemes, this device can significantly improve the disinfection efficiency and ensure the health and safety of people.

[0003] The spray disinfection and sterilization device in public places is a special device for disinfecting and removing odors in public places. It mainly consists of a high-pressure spray system and a disinfection agent. The proportionally mixed disinfection agent is pressurized to more than 4 bar by a high-pressure pump, and then sent to a high-pressure nozzle through a high-pressure pipeline for atomization to form scattered water mist. The characteristics of the spray disinfection and sterilization device are that the mist particles ejected are fine and uniform, can be quickly dispersed, and can achieve disinfection without dead corners. In addition, it can not only disinfect, but also deodorize, eliminate static electricity, purify the air, and even generate negative oxygen ions while spraying, increasing the oxygen content in the air and making the air fresher.

[0004] In the shutdown state of the existing spray disinfection and sterilization device, that is, when the spraying stops, since the nozzle will lock the liquid in the state of less than 1 bar or no pressure due to the spring seal ring, after the pump stops, there is still a reduced pressure in the pipeline. At this time, the liquid in the pipeline cannot be atomized by the nozzle and can only drip in the form of drops to slowly consume the pressure in the pipeline, resulting in unnecessary waste of the disinfection agent. At the same time, water droplets are also formed on the space ground, causing the ground to be slippery. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the utility model provides an atomization device for space purification, which relieves the pressure in the pipeline through a pressure relief valve so that the nozzle does not drip water in the stopped state.

[0027] The present utility model will be further described in detail below with reference to the accompanying drawings. The following is an explanation rather than a limitation of the present utility model.

[0028] Refer to Figures 1-3 , an atomization device for space purification, comprising a spray component, a pump 7, a pressure relief device and a control unit;

[0029] The water outlet end of the pump is connected to the water inlet end of the spray component, the water inlet end of the pump is connected to a water source, the water inlet end of the spray component is connected to the pressure relief device through a return water pipeline 8, and the pump and the pressure relief device work alternately; the control unit is respectively connected to the pump and the pressure relief device, and determines a water shortage fault according to the load parameters of the pump.

[0030] The pump is one of the core components of the atomization device. Its main function is to pressurize and transport the disinfection liquid from the water source to the spray head 3 or nozzle of the spray component, and atomize it into dispersed water mist through a high-pressure nozzle to disinfect and remove odors from the space. The spray head 3 is composed of parts such as a housing, a nozzle, a spring, and a pipeline. The spray head 3 is used to release the liquid in the form of mist or spray; the pump and the pressure relief device of this atomization device work alternately. When the pump stops working, the pressure relief device opens, and the remaining liquid in the spray component is discharged through the return water pipeline 8. When the pump works, the pressure relief device closes. At this time, the pressure relief device closes the return water pipeline 8, so that the disinfection liquid enters the spray component, and the pressure in the spray component is reduced through the pressure relief component, solving the problem that the remaining liquid in the spray component drips in the form of water droplets under the residual pressure when the pump stops working; in addition, the present utility model obtains the load parameters of the pump through the control unit and uses them as the judgment standard for water shortage faults, thereby realizing the real-time diagnosis of water shortage faults of the atomization device.

[0031] The pump is a peristaltic pump or a diaphragm pump.

[0032] Peristaltic pumps use rollers or pressing blocks to roll on a hose, generating a squeezing effect to transport liquids. Peristaltic pumps can provide a steady flow rate and do not generate shear force or contamination to the liquid. They are suitable for transporting high-purity purifying agents, and peristaltic pumps can precisely control the flow rate to reduce the waste of disinfection liquid.

[0033] Diaphragm pumps draw liquids from one side to the other through a reciprocating diaphragm and discharge them through the outlet. Diaphragm pumps can handle liquids containing particles or viscosity and have a self-priming function in some cases. Diaphragm pumps have the characteristics of simple structure and convenient maintenance, meeting the requirements for liquid transportation in space purification systems.

[0034] The spraying assembly includes a spraying pipeline 1 and spray heads 3; one end of the spraying pipeline 1 is connected to the water outlet end of the pump, and the other end is provided with branch pipes 5. A plurality of spray heads 3 are arranged at intervals on the branch pipes 5, and a wide-range disinfection and odor removal work is carried out through the plurality of spray heads 3 to improve work efficiency.

[0035] The branch includes at least one. When there is one branch pipe, the middle of the branch pipe is connected to the upper end of the spraying pipeline 1, and both ends of the branch pipe extend to both sides. When there are multiple branch pipes, one ends of the multiple branch pipes are closed, and the other ends are all connected to the spraying pipeline 1 through a porous joint, and the multiple branch pipes are circumferentially distributed.

[0036] The pressure relief device is a pressure relief solenoid valve 6. The pressure relief solenoid valve 6 is a normally open solenoid valve. The pressure relief solenoid valve 6 is arranged on the return water pipeline 8. One end of the return water pipeline 8 is communicated with the spraying pipeline 1, and the other end is connected to the water source. In this application, when the pump stops working, the control unit sends an opening control signal, the pressure relief solenoid valve 6 is powered off, the magnetic field of the electromagnet fails, and the valve opens. The liquid in the spraying pipeline 1 flows back to the water source through the return water pipeline 8. When the pump is working, the control unit sends a closing control signal, and under the action of the magnetic field of the electromagnet, the valve will close to prevent the liquid from passing through the return water pipeline 8.

[0037] During the diagnosis of the water shortage fault, by obtaining the current of the pump under the load state, the water shortage fault is determined according to the load current. For example, when the pump is in the normal state, the load current is 1A. When in the water shortage state, the load of the pump decreases, and its load current also changes accordingly. At this time, the load current becomes smaller. When the load current is less than the set threshold range, it can be determined that the water source is short of water, and the control unit sends a water shortage fault signal.

[0038] A current sensor is used to obtain the load current of the pump. A water pump induction circuit can also be set in the control circuit to obtain the load current of the water pump. The control unit compares the real-time load current with the set threshold. When the load current exceeds the threshold range, an alarm signal can be output.

[0039] The water source is divided into a flowing water source and a fixed water source. The flowing water source is a normally open faucet, and the fixed water source is a water storage tank.

[0040] The pump, pressure relief device and control unit are arranged in a sealed box body. One side of the box body is provided with a fixing structure for fixing the sealed box body on the wall.

[0041] Refer to Figure 4 , a control method for an atomizing device for space purification, comprising the following steps:

[0042] Step 1: Enter the atomizing system according to the identity information.

[0043] Input a login instruction into the control interface of the atomizing system to enter the atomizing system. The login instruction is the user name and the corresponding password, and it can also be a biological instruction, for example, fingerprint, voice, palmprint, face recognition method to enter the atomizing system.

[0044] When the user has no login instruction in the atomizing system, the user needs to perform identity registration to obtain a legal login instruction.

[0045] Step 2: Obtain the identification information of the target atomizing device, and obtain the control information of the target atomizing device according to the identification information.

[0046] There are several atomizing devices in an atomizing system. Each atomizing device is given corresponding identification information. After logging in to the atomizing system, it can be connected to the control unit of the atomizing device through the identification information. For example, the identification information is the identity two-dimensional code of the atomizing device. By scanning the two-dimensional code on the mobile phone side, the mobile phone side can be connected to the control end of the atomizing device.

[0047] Step 3: Control the operating state of the atomizing device through the control end. When the operating state is abnormal, an alarm signal is output.

[0048] Control the spray interval time of the atomizing device, timed spraying, view the liquid volume in the water tank, modify the name of the atomizing device, and view the operation log of the atomizing device.
