Unless expressly stated or limited otherwise, the term "coupled" is to be construed broadly, e.g., as meaning both fixedly and movably coupled, detachably and non-detachably coupled, or integrally coupled; may be mechanically or electrically connected or may be in communication with each other. And "fixedly connected" includes detachably connected, non-detachably connected, integrally connected, and the like. The use of terms like "first" or "second" in this disclosure are used for descriptive purposes only and are not to be construed as indicating or implying any relative importance or implicit to the technical feature indicated. The technical solutions between the embodiments of the present invention should be capable of being combined with each other.

The sterilization and deodorization device 1000 provided by the embodiment of the utility model is suitable for narrow spaces with peculiar smell and germs in a residential toilet, a residential closed balcony, a residential kitchen, a bathroom in a market, a hospital ward and the like. It will be appreciated that the germicidal and odor removal apparatus 1000 may also be used in a relatively wide space.

Referring to fig. 1, the sterilization and odor removal device 1000 includes a housing 100, an atomizing chamber 200, a control chamber 300, and an electrolysis chamber 400. The nebulization chamber 200, the control chamber 300 and the electrolysis chamber 400 are all located within the housing 100, and the nebulization chamber 200 and the electrolysis chamber 400 are at least partially separated. "at least partially isolated" means that they are not necessarily completely sealed from one another, but rather are divided into different chambers in partial regions separated by the relevant components.

Further, the atomizing chamber 200, the control chamber 300, and the electrolysis chamber 400 are at least partially separated from each other. Fig. 1 shows that the housing 100 has an atomizing chamber 200, a control chamber 300, and an electrolytic chamber 400 arranged therein from top to bottom. It is understood that the atomizing chamber 200, the control chamber 300 and the electrolytic chamber 400 may be arranged in other forms, for example, the three are horizontally distributed in a left-middle-right direction, so as to ensure that the atomizing chamber 200, the control chamber 300 and the electrolytic chamber 400 are at least partially separated from each other. Thus, the electrolytic liquid in the electrolytic chamber 400 does not flow to the atomizing chamber 200 or the control chamber 300 in a large amount.

Referring to fig. 1 and 2, an electrolytic electrode 410 is disposed in the electrolytic chamber 400. The electrolysis electrode 410 can be connected to the mains. When water is electrolyzed, there are direct reaction and indirect reaction. In the direct reaction, bacteria or organic molecules in the air or water environment will be adsorbed to the surface of the electrolysis electrode. Under the action of electric energy, organic matters forming bacteria are destroyed, so that molecular bonds of the organic matters are broken, and sterilization is realized to a certain extent; in the indirect reaction, the anode of the electrolysis electrode undergoes an oxidation reaction. At the electrode surface, water is electrolyzed to produce an intermediate product having active oxygen. When bacteria or organic molecules in the environment approach the surface of the electrode, the bacteria are immediately oxidized and decomposed by active oxygen with strong oxidizing property, and the bacteria are also destroyed under the action. Tap water usually contains chlorine element, and electrolysis of the tap water generates chlorine-containing sterilization components, so that the sterilization effect is further improved.

An atomizing element is disposed within the atomizing chamber 200. The atomizing element breaks up liquid water molecule structures such as electrolyte in the atomizing cavity to generate fine mist, and the fine mist can be rapidly diffused into ambient air. In the case of a residential toilet, the odor is mostly derived from ammonia gas. Ammonia is readily soluble in water. The diffused mist allows the ammonia gas to be in full contact with liquid molecules, thereby effectively reducing the odor from the ammonia gas.

The traditional sterilization and deodorization device is also provided with an electrolysis cavity and an atomization cavity, and an electrolysis electrode is arranged in the electrolysis cavity. If the electrolyte generated by electrolyzing tap water is contacted with the metal material in the sterilizing and deodorizing device, the metal material element (especially the metal material element in the atomizing cavity) is easily subjected to electrochemical corrosion, and the service life of the product is further influenced.

The sterilization and odor removal device 1000 in the embodiment of the utility model partially separates the electrolysis chamber from the atomization chamber, so that the electrolysis process has less influence on the atomization process, thereby reducing the electrochemical corrosion of the electrolyte on other metal material elements.

Referring to fig. 1 and 2, a circuit board 310 for controlling the operation of the sterilization and odor removal device 1000 is disposed in the control chamber 300. The circuit board 310 is electrically connected to both the electrolysis electrode 410 and the atomizing element 210. The control element on the circuit board 310 can control the switching of the on-state and the off-state of the sterilizing and deodorizing device 1000.

Further, the sterilization and odor removal device 1000 has a first operation mode and a second operation mode. The first working mode is an electrolysis mode: the water in the electrolytic chamber 400 is electrolyzed to obtain an electrolyte; the second working mode is an atomization mode: the liquid is atomized and discharged in the atomizing chamber 200. The sterilization and deodorization device 1000 is provided with a switch element for controlling the first operation mode and the second operation mode.

Referring to fig. 1 to 3, the housing 100 is provided with a mist outlet 110, and the atomizing chamber 200 is communicated with the mist outlet 110. Fig. 1 and 3 also show that the top of the housing 100 is provided with a control panel 120 and a filler 130. The bottom of the two sides of the casing 100 is provided with an air inlet 160, and outside air can enter the inside of the sterilization and odor removal device 1000 through the air inlet 160. The back of the housing 100 is provided with a mounting hole 170, and the mounting hole 170 enables the sterilization and odor removal device 1000 to be mounted on a wall or the like. It is understood that the mist outlet 110, the control panel 120, the filler 130, the air inlet 160, and the mounting hole 170 may be located at other positions of the housing 100.

Specifically, the housing 100 is provided with a switch element for controlling a first operation mode and a second operation mode, so as to divide the operation state of the sterilization and odor removal device 1000 into the first operation mode and the second operation mode. The switching element may be two switches of a first operation mode switch and a second operation mode switch, or may be one changeover switch that can switch between the first operation mode and the second operation mode.

Further, the switch element of the sterilization and odor removal device 1000 is a switch, which can be switched between a first operation mode and a second operation mode. The two switches of the first working mode switch and the second working mode switch are arranged, so that the problem of how the sterilization and odor removal device 1000 responds under the condition that a user presses the two switches simultaneously needs to be solved. The existence of the switch enables the sterilization and deodorization device 1000 to work only in one of the first working mode and the second working mode. It will be appreciated that the diverter switch can be implemented in a number of ways, such as a diverter knob and a push button similar to the operating principle of a single pole double throw switch. The switching knob is in the rotation process, and the protruding structure of knob is intermittently communicated with the contact piece to generate a trigger signal. The new working mode is switched to each time the trigger signal is generated. The key similar to the single-pole double-throw switch in working principle can be communicated with one circuit after being pressed down, and only one of the first working mode and the second working mode can be in a working state. It should be noted that there are many implementations of the switch, and the above examples should not be considered as limitations to the specific implementations of the switch.

Referring to fig. 1, a pump is further disposed in the control chamber 300, a water inlet of the pump is communicated with the electrolysis chamber 400 through a first pipeline, and a water outlet of the pump is communicated with the atomization chamber 200 through a second pipeline. The pump is also electrically connected to the circuit board 310 so that the pump is controlled by the circuit board 310.

The atomizing element in the atomizing chamber 200 functions properly and requires a certain amount of liquid for atomization. In order to ensure that the atomizing element is in operation with the liquid required for atomization in the atomizing chamber 200, a pump is used to continuously feed liquid, such as tap water, into the atomizing chamber 200. It should be noted that, unless otherwise specified, the meaning of "piping" in the description of the present invention is not limited to the case where a solid pipe body (for example, a silicone hose) is additionally provided as the piping, but also includes the case where a passage (for example, a long groove on a wall surface of one side of the housing 100) provided in the housing 100 itself is used as the piping.

As shown in fig. 1, the housing 100 corresponding to the control chamber 300 is further provided with a first connection port and a second connection port. The water inlet of the pump is connected with a first connecting port through a silica gel hose, and the first connecting port is communicated with the electrolysis cavity 400; the delivery port and the second connector of pump are connected with the silica gel hose, and the second connector communicates with atomizing chamber 200 to the pump can be with the liquid of electrolysis chamber 400 constantly carry to atomizing chamber 200, and then makes to have the required liquid of atomizing in atomizing chamber 200 when atomizing element work. The first port is located substantially at the bottom of the control chamber 300 and the second port is located substantially at the top of the control chamber 300. After the electrolyzed liquid is atomized, ammonia gas can be better dissolved and sterilized, and the aim of removing peculiar smell is further fulfilled. The components in the atomizing chamber 200 are selected from materials that are chemically resistant. Therefore, even if the electrolyzed liquid enters the atomizing chamber 200, chemical corrosion is not caused substantially. However, the atomization chamber 200 should prevent electrochemical corrosion from occurring, and therefore should separate the electrolysis process from the atomization process.

Specifically, as shown in fig. 1 and fig. 2, the pump in the sterilization and odor removal device 1000 is a diaphragm pump 320. The diaphragm pump 320 uses a motor to drive the diaphragm to reciprocate to create a vacuum, thereby drawing in and forcing out liquid. The diaphragm pump 320 separates the fluid to be infused from the plunger and the pump cylinder by means of a film, thereby protecting the plunger and the pump cylinder. The diaphragm pump 320 has the following advantages in comparison: the working efficiency is higher; the motion mechanism is isolated from the conveying medium, so that the medium is not polluted; the sealing effect is good, and leakage is less; the noise of the device is low. Therefore, the diaphragm pump is selected as the actuator of the sterilization and odor removal device 1000 for delivering liquid in the embodiment of the present invention.

Referring to fig. 1 and 2, the atomizing chamber 200 is located above the electrolytic chamber 400, and the atomizing chamber 200 is communicated with the electrolytic chamber 400 in a partial region, so that the liquid in the atomizing chamber 200 can flow back to the electrolytic chamber 400. Specifically, as shown in fig. 1 and 2, the first partition 150 in the housing does not completely enclose the nebulizing chamber 200. Excess liquid above the height of the first partition 150 will flow back down the first partition 150 or the wall of other areas of the housing 100, past the first partition 150, and back into the electrolysis chamber 400. When the liquid in the atomizing chamber 200 is too much, the excessive liquid can flow back to the electrolytic chamber 400 under the action of its own weight, so that the liquid in the sterilizing and deodorizing device 1000 is not wasted.

In an alternative embodiment, the atomizing chamber 200 is located above the electrolytic chamber 400, and the atomizing chamber 200 is communicated with the electrolytic chamber 400 through a third pipeline, which is used for returning the liquid in the atomizing chamber 200 to the electrolytic chamber 400. It will be appreciated that the third conduit may still be a passage formed by an elongated slot in the wall of the housing 100. One side of the atomizing chamber 200 is communicated with the electrolytic chamber 400 through a long groove-shaped passage. The excess liquid in the atomizing chamber 200 can flow back to the electrolytic chamber 400 along the elongated slot-shaped channel.

As an alternative, the return line may also be provided with a non-return valve. In other words, the nebulizing chamber 200 communicates with the electrolytic chamber 400 through a fourth line provided with a one-way valve that allows only the liquid in the nebulizing chamber 200 to flow back to the electrolytic chamber 400. It will be appreciated that the return flow path is defined to be from the nebulizing chamber 200 to the electrolysis chamber 400 only, by virtue of the action of the one-way valve. Even if the nebulizing chamber 200 is not located above the electrolytic chamber 400, the flow of excess liquid is not under the influence of its own weight, and the one-way valve can still ensure that the liquid flows only from the nebulizing chamber 200 back to the electrolytic chamber 400.

As shown in fig. 2, the atomizing element is an ultrasonic atomizing plate 210, and the ultrasonic atomizing plate 210 is electrically connected to the circuit board 310. The atomized particles produced by the ultrasonic atomization sheet 210 are relatively uniform in size, making it easier for air to adequately contact the atomized particles. The ultrasonic atomization sheet 210 breaks up liquid water molecules by electronic high-frequency oscillation (the oscillation frequency exceeds the human auditory range, so that the human body and the animals are not damaged), and generates water mist. Specifically, the ultrasonic atomization sheet 210 is a ceramic ultrasonic atomization sheet.

As shown in fig. 2, a first partition 150 and a second partition are disposed in the housing 100, the second partition and the first partition 150 define a space of the atomization chamber, and a maximum liquid level of the atomization chamber 200 is determined by a height of the first partition 150. Specifically, the first partition 150 is vertically disposed (as shown in fig. 2), and the second partition is horizontally disposed. Proper operation of the atomizing element typically requires that the atomizing target maintain a range of liquid level heights, particularly the ultrasonic atomizing plate. When the ultrasonic atomization sheet is electrified under the condition of insufficient liquid, the pulse current for starting the operation can burn the atomization sheet per se. However, if the liquid is too deep, the high-frequency oscillation effect of the ultrasonic atomization sheet is not good, and the atomization effect is deteriorated. In the atomizing chamber 200 of the sterilization and odor removal device 1000 in the embodiment of the present invention, the liquid that exceeds the height of the first partition 150 overflows, so that the liquid level in the atomizing chamber 200 is maintained within a certain height range. With a simple structure of the partition plate, the liquid level in the atomizing chamber 200 can be maintained within a certain height range, as compared with other methods. Under the condition of not adopting complex components, the control of the liquid level height range is realized, and the device has the advantages of low cost, safety and reliability.

Specifically, for the ultrasonic atomization sheet 210, the height of the first partition 150 preferably ranges from 1cm to 3 cm.

In an alternative embodiment, a liquid level sensor is disposed in the nebulizing chamber 200, and the liquid level sensor and the pump are electrically connected to the circuit board 310. The liquid level sensor comprises a contact type liquid level switch and a non-contact type liquid level switch. The contact type liquid level switch includes a float type liquid level switch and the like, and the non-contact type switch includes a capacitance type liquid level switch and the like. The liquid level sensor detects the liquid level in the atomizing chamber 200 and outputs a signal to the control element of the circuit board 310. The control element of the circuit board 310 controls the start or stop of the pump when determining that the liquid level in the atomizing chamber 200 is out of the preset range, so as to adjust the page height to the preset range. It is to be understood that the liquid level may be controlled within a suitable range, and a liquid level control valve or the like may be used. The level control valve includes a floating ball type level control valve.

Referring to fig. 1 and 2, a fan is disposed in the housing 100, the fan is electrically connected to the circuit board 310, the housing 100 is provided with an air inlet 160 and a mist outlet 110, and the fan is configured to promote the air flow to be sucked into the air inlet 160 and discharged from the mist outlet 110. Specifically, the air inlets 160 are disposed at the bottom of both sides of the housing 100, i.e., the air flow from the outside is introduced from the two air inlets 160 disposed at the bottom of the sides of the housing 100. The fan causes the air flow to the atomizing chamber 200 through the air duct, and discharges the electrolyzed water in a fine mist state from the mist outlet 110, thereby rapidly diffusing the electrolyzed water to the environmental space. The fan can accelerate the fine mist diffusion of the sterilization and deodorization device 1000. Specifically, the fan is a centrifugal fan, and the centrifugal fan is located in the control chamber 300. The centrifugal fan can generate large wind pressure, so that the flowing of the airflow and the diffusion of the fine mist are accelerated remarkably. It is understood that the fan may be an axial fan.

Referring to fig. 1 and 2, a water storage cavity 500 is further disposed in the housing 100, and the first partition 150 at least divides the space inside the housing 100 into the atomizing cavity 200 and the water storage cavity 500.

With continued reference to fig. 1 and 2, the bottom of the water storage chamber 500 is in communication with the electrolysis chamber 400 via a filter element 510. As shown in fig. 1, the water storage chamber 500 is located at the front portion in the housing 100, and the atomization chamber 200, the control chamber 300, and the electrolysis chamber 400 are located at the rear portion in the housing 100. The atomization chamber 200, the control chamber 300 and the electrolysis chamber 400 are separated from the water storage chamber 500 by a first partition 150 in a partial region. The first partition 150 does not completely separate the nebulizing chamber 200 from the water storage chamber 500, and thus the excess liquid in the nebulizing chamber 200 can overflow over the first partition 150.

Fig. 3, fig. 4, fig. 5 and fig. 6 are schematic diagrams showing different directional viewing angles of the sterilizing and deodorizing device 1000. The specific structure of the sterilization and odor removal device 1000 can be more clearly understood by referring to fig. 1 and 2. As shown in FIG. 2, the dashed arrows indicate the liquid flow direction of the sterilization and odor removal device 1000. The user adds water to the sterilizing and deodorizing device 1000 through the water adding port 130, and the added water enters the water storage chamber 500. The bottom of the water storage chamber 500 communicates with the electrolysis chamber 400 through a filter element 510. The water filtered by the filter element 510 enters the electrolytic chamber 400 to form an electrolyte. The electrolyte is pumped into the nebulization chamber 200. The atomization in the atomization chamber 200 through the atomization element forms a fine mist, and the fine mist is discharged from the mist outlet 110 of the housing 100.

Referring to fig. 1, a secondary battery is disposed in the housing 100, and the secondary battery is at least used for supplying power to the circuit board 310 and the atomizing element. The process of electrolyzing water requires a large amount of electrical energy to be consumed. Therefore, the sterilization and odor removal device, which is usually equipped with an electrolysis chamber and an atomization chamber, works under the condition that the mains supply is connected. However, the sterilizing and deodorizing device connected with the commercial power is poor in portability and mobility. If a common battery is used for power supply, the common battery with larger volume is required to ensure the cruising ability, so that the common battery is difficult to be applied to narrow space places such as a residential toilet and the like.

The secondary battery is adopted, so that the sterilization and odor removal device can be repeatedly used, and the volume of the whole sterilization and odor removal device is not too large. Specifically, as shown in fig. 1 and 2, the secondary battery is a lithium battery 360, and the lithium battery 360 is located in the control chamber 300. The lithium battery 360 is used to supply power to the diaphragm pump 320, the ultrasonic atomization sheet 210, the centrifugal fan, the circuit board 310, and the like. It is understood that the secondary battery may be a nickel-metal hydride battery, a nickel-cadmium battery, a lead-acid battery, a lithium polymer battery, or the like.

Specifically, the sterilization and odor removal device 1000 according to the embodiment of the present invention has a first operation mode and a second operation mode. The time required for charging the lithium battery is equivalent to the time required for electrolyzing water. Therefore, when the lithium battery is charged, the tap water in the sterilization and deodorization device 1000 is substantially electrolyzed. Thus, the first mode of operation may be specifically an electrolysis-charging mode, while the second mode of operation is a discharge-atomization mode.

In the electrolysis-charging state, the sterilization and deodorization device 1000 is connected with the mains supply under the condition of being filled with tap water. The electrolysis electrode 410 in the electrolysis chamber 400 operates to electrolyze tap water. At the same time, the commercial power charges the lithium battery 360 in the control chamber 300.

In the discharge-atomization state, the sterilization and odor removal device 1000 is left standing or suspended on the wall surface of a place such as a toilet. In normal operation, the lithium battery 360 supplies power to the various components within the control chamber 300. The electrolyte in the electrolytic chamber 400 is delivered into the atomization chamber 200 through the diaphragm pump 320, and the ultrasonic atomization sheet 210 generates high frequency oscillation, thereby atomizing the liquid in the atomization chamber 200. The atomized liquid is diffused to the indoor space through the mist outlet 110, so that the sterilization and odor removal operation is completed.

In the description herein, references to "one embodiment," "another embodiment," and "certain embodiments," "some examples," and the like, mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the utility model. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example.
