Description

Technical Field

[0001] The present invention belongs to the technical field of disinfection and sterilization equipment, and relates to an ozone water mist generator for a disinfection and sterilization robot. Background Art

[0002] In recent years, disinfection and sterilization robots have become increasingly popular. The disinfection and sterilization robots in the prior art include a mobile base, a water tank, an ozone water mist generator, a spray pipe, and an outer cover. The water tank and the ozone water mist generator are both installed on the mobile base and connected through pipelines. The spray pipe is installed on the ozone water mist generator and penetrates through the outer cover to communicate with the outside. Various components for the robot to identify road conditions and control start and stop are also installed on the base. The ozone water mist generator is specifically in a box shape, with a cavity inside. A mist outlet is opened on the outer wall of the top. A high-frequency oscillator is arranged at the bottom of the cavity inside the ozone water mist generator. A fan is installed at the top of the cavity (specifically at the inlet of the mist outlet). An air inlet communicating with the cavity is opened on the ozone water mist generator. When working, the water tank inputs tap water into the ozone water mist generator through a pipeline. The electrode group in the ozone water mist generator energizes the tap water to electrolyze it into a mixture of water and ozone (i.e., ozone water). At the same time, the ozone water is atomized by the vibration of the high-frequency oscillator, and the ozone water mist is input into the spray pipe through the mist outlet by the negative pressure generated by the rotation of the fan and sprayed to the outside.

[0003] However, the above-mentioned disinfection and sterilization robot has relatively large defects, specifically manifested as follows: When the fan starts, the airflow will carry the ozone water mist through the fan, the mist outlet, and into the spray pipe in sequence. During this process, the ozone water mist formed by vibration will be divided into two parts. One part normally passes through the fan, the mist outlet, and into the spray pipe, while the other part adheres to the fan blades and re-condenses into water droplets during the process of passing through the fan, and then re-falls into the ozone water under the centrifugal action of the fan blades, resulting in a reduction in the actual sprayed amount of the ozone water mist, making the disinfection and sterilization effect of the disinfection and sterilization robot unable to reach the original expectation. Summary of the Invention

[0004] The object of the present invention is to propose an ozone water mist generator for a disinfection and sterilization robot in view of the above problems existing in the prior art. The technical problem to be solved by the present invention is: how to improve the disinfection and sterilization effect of the disinfection and sterilization robot.

[0005] The object of the present invention can be achieved by the following technical solutions: An ozone water mist generator for a disinfection and sterilization robot, comprising a housing, a high-frequency oscillator is provided at the bottom inside the housing. It is characterized in that a vertically arranged ventilation pipe is provided on the bottom wall of the housing, and the upper end of the ventilation pipe has a ventilation opening communicating with the inner cavity of the housing. A fan is installed on the outer wall of the housing at the lower end port of the ventilation pipe. An atomizing pipe is provided vertically above the high-frequency oscillator at the top of the housing. The lower end of the atomizing pipe has a fog inlet, and an air inlet is opened on the side wall of the atomizing pipe. Both the fog inlet and the air inlet communicate with the inner cavity of the housing, and the height of the ventilation opening of the ventilation pipe is higher than the height of the fog inlet.

[0006] The ozone water mist generator of this disinfection and sterilization robot includes a housing, and there is a cavity inside the housing, and an electrode group for electrolyzing tap water is installed in the cavity. During the disinfection and sterilization work, the high-frequency oscillator installed on the bottom wall inside the housing can atomize the ozone water in the cavity of the housing into ozone water mist by vibrating. At the same time, the fan installed on the outer wall of the housing works to generate an air flow. The air flow enters through the lower end port of the ventilation pipe in sequence and enters the cavity of the housing through the ventilation opening at the upper end of the ventilation pipe, and then flows out of the housing through the atomizing pipe. It is worth mentioning that since the height of the fog inlet opened at the bottom of the atomizing pipe is lower than the ventilation opening at the upper end of the ventilation pipe, when the air flow flows in the housing, a part of the air flow can flow in the lower part of the cavity of the housing. At this time, this part of the air flow can push the ozone water mist formed by vibration upward. At the same time, when the air flow enters the atomizing pipe from the air inlet, the flow rate of the air flow entering the atomizing pipe from the air inlet increases, so that a negative pressure suction effect can be formed in the atomizing pipe. By separately transporting the air flow and the ozone water mist, the ozone water mist is sucked into the atomizing pipe under the negative pressure and mixed with the air flow, and then sprayed out through the nozzle connected to the atomizing pipe, avoiding the problem of high transmission loss rate of ozone water mist in the prior art, improving the transmission efficiency of ozone water mist outward, and thus improving the disinfection and sterilization effect of the disinfection and sterilization robot.

[0007] In the above-mentioned ozone water mist generator of the disinfection and sterilization robot, a plurality of the air inlets are circumferentially spaced apart on the side wall of the atomizing pipe.

[0008] The number of the air inlets is several, and several air inlets are spaced along the circumferential side wall of the atomizing pipe, so that the air flow entering the atomizing pipe from the air inlet can better form a swirl, thereby improving the negative pressure effect in the atomizing pipe, ensuring the transmission efficiency of the ozone water mist outward, and thus improving the disinfection and sterilization effect of the disinfection and sterilization robot.

[0009] In the ozone water mist generator of the above-mentioned disinfection robot, the housing includes an upper shell and a lower shell that are detachably connected. The mist outlet pipe is injection-molded inside the upper shell, and the ventilation pipe is injection-molded inside the lower shell. A partition plate is provided between the mist outlet pipe and the ventilation pipe inside the upper shell. The partition plate divides the cavity inside the upper shell into a ventilation cavity and a mist-forming cavity. One side of the partition plate is fixedly connected to the inner wall of one side of the upper shell, and an air passing gap for communicating the ventilation cavity and the mist-forming cavity is formed between the other side and the inner wall of the other side of the upper shell.

[0010] The housing is formed by detachably connecting the upper shell and the lower shell, which facilitates the disassembly and assembly of the electrode group installed inside the housing. Moreover, the ventilation pipe is vertically arranged inside the lower shell by injection molding, and the mist outlet pipe is vertically arranged inside the upper shell by injection molding, thereby ensuring the connection stability of the ventilation pipe and the mist outlet pipe. When the upper shell and the lower shell are buckled, the upper end of the ventilation pipe extends into the upper shell, so that a certain height difference is formed between the mist inlet on the mist outlet pipe and the ventilation opening at the upper end of the ventilation pipe. And a partition plate is provided inside the upper shell. The partition plate divides the cavity inside the upper shell into a ventilation cavity and a mist-forming cavity. The upper end of the ventilation pipe extends into the ventilation cavity, and the mist outlet pipe is located in the mist-forming cavity. One side of the partition plate is fixedly connected to the inner wall of one side of the upper shell, and an air passing gap is formed between the other side and the inner wall of the other side of the upper shell. During the actual working process, due to the existence of the partition plate, the air flow entering the housing through the ventilation opening can be guided by the inner wall of the ventilation cavity and the inner wall of the mist-forming cavity, and the air flow enters the mist-forming cavity from the ventilation cavity through the air passing gap. On the premise that the air flow velocity remains relatively unchanged, the air flow velocity entering the mist-forming cavity is further increased, thereby improving the efficiency of outward transmission of ozone water mist.

[0011] In the ozone water mist generator of the above-mentioned disinfection robot, a diversion gap is formed between the partition plate and the inner bottom wall of the lower shell, and the height of the diversion gap is lower than that of the ventilation opening.

[0012] A diversion gap with a height lower than that of the ventilation opening is formed between the partition plate and the inner bottom wall of the lower shell. During the air flow process, the air flow is specifically divided into two parts. One part enters the mist-forming cavity through the air passing gap, and enters the mist outlet pipe through the air inlet to form a negative pressure inside the mist outlet pipe, while the other part enters the mist-forming cavity through the diversion gap, so that the ozone water mist formed by vibration can be pushed by this part of the air flow towards the mist inlet of the mist outlet pipe.

[0013] In the ozone water mist generator of the above-mentioned disinfection robot, the ventilation opening is opened on the side wall of the upper end of the ventilation pipe and faces the inner wall of the upper shell, and the circumferential inner wall of the mist-forming cavity is arc-shaped.

[0014] The ventilation opening is provided on the upper side wall of the ventilation pipe, and the ventilation opening faces the inner wall of the upper shell, rather than the air inlet of the fog outlet pipe, so as to avoid the ozone water mist from directly blowing and re-condensing into water droplets on the inner wall of the upper shell, thereby avoiding the loss of the ozone water mist. In addition, since the inner wall of the fog-forming cavity is arc-shaped, the air flow can flow along the inner wall of the fog-forming cavity and around the fog outlet pipe after passing through the air passing gap, so that the air flow can enter the fog outlet pipe from the air inlet at a relatively high flow rate, thereby ensuring a higher negative pressure in the fog outlet pipe and improving the ozone water mist transportation efficiency.

[0015] In the ozone water mist generator of the above-mentioned disinfection robot, each air inlet is strip-shaped. One end of each air inlet extends to the lower end of the fog outlet pipe, and the other end extends to the inner wall of the top of the upper shell, and the upper end of the fog outlet pipe protrudes from the outer wall of the top of the upper shell.

[0016] One end of each air inlet extends to the lower end of the fog outlet pipe, and the other end extends to the inner wall of the top of the upper shell, so that the length of the area where negative pressure is formed in the fog outlet pipe is longer, ensuring the transportation efficiency of the ozone water mist. And since each air inlet is strip-shaped, the probability of the ozone water mist contacting the inner wall of the fog outlet pipe is reduced, and the loss rate of the ozone water mist during transportation is reduced. In addition, the upper end of the fog outlet pipe protrudes from the outer wall of the top of the upper shell, so that the nozzle can be directly clamped and fixed at the upper end of the fog outlet pipe subsequently, thereby ensuring the assembly convenience.

[0017] In the ozone water mist generator of the above-mentioned disinfection robot, the circumferential side wall at the lower end of the upper shell extends downward to form an extension part, and the extension part extends into the lower shell.

[0018] The circumferential side wall at the lower end of the upper shell extends downward to form an extension part. When the upper shell and the lower shell are buckled together, the extension part can extend into the lower shell, so that the distance between the lower end of the upper shell and the inner bottom wall of the lower shell is smaller. When the high-frequency oscillator vibrates to form ozone water mist, the activity range of the ozone water mist can be reduced through the extension part, thereby guiding the formed ozone water mist to ensure that the ozone water mist enters the fog outlet pipe more efficiently through the fog inlet with a smaller loss rate.

[0019] In the ozone water mist generator of the above-mentioned disinfection robot, an installation opening is provided at the bottom of the lower shell, and the high-frequency oscillator is embedded in the installation opening and is fixedly screwed to the lower shell by screws.

[0020] The high-frequency oscillator is specifically embedded in the installation opening provided at the bottom of the lower shell and is fixedly screwed to the bottom of the lower shell by screws, so as to ensure the normal operation of the high-frequency oscillator and facilitate subsequent disassembly and maintenance.

[0021] In the ozone water mist generator of the above-mentioned disinfection robot, an upper fixing plate is injection-molded on the outer circumferential wall of the upper shell, and a lower fixing plate is injection-molded on the outer circumferential wall of the lower shell. The upper fixing plate and the lower fixing plate are fixedly screwed together by bolts.

[0022] An upper fixing plate is injection-molded on the outer wall of the upper shell, and a lower fixing plate is injection-molded on the outer wall of the lower shell. A plurality of upper fixing holes are circumferentially formed in the upper fixing plate, and a plurality of lower fixing holes are circumferentially formed in the lower fixing plate. The upper shell and the lower shell are fixed by bolts passing through the upper fixing holes and screwing into the lower fixing holes. It can be disassembled on the premise of ensuring the stable connection between the two, which is convenient for later maintenance work.

[0023] In the ozone water mist generator of the disinfection robot described above, an installation groove for embedding a sealing ring is circumferentially formed on the upper side surface of the lower fixing plate.

[0024] An installation groove is circumferentially formed on the upper side plate surface of the lower fixing plate, and a sealing ring is embedded in the installation groove. The installation position of the sealing ring is positioned through the installation groove. When the upper shell and the lower shell are snap-connected, the sealing ring can block the gap between the upper shell and the lower shell, thereby preventing the ozone water in the shell from leaking out through the gap between the upper shell and the lower shell due to the vibration during the movement of the disinfection robot.

[0025] Compared with the prior art, the ozone water mist generator of the present disinfection robot has the following advantages:

[0026] In the present disinfection robot, the airflow input into the shell by the branch machine through the ventilation pipe pushes the ozone water mist floating in the shell to converge at the fog inlet of the fog outlet pipe, and the airflow enters the fog outlet pipe from the air inlet of the fog outlet pipe to form a negative pressure in the fog outlet pipe. The ozone water mist is sucked in through the negative pressure, mixed with the airflow and then sprayed outwards. During the conveying process, the conveying efficiency is improved on the premise of avoiding the loss of ozone water mist, ensuring the disinfection effect of the disinfection robot.

Specific embodiments

[0035] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0036] As Figure 1-2 shown, the ozone water mist generator of this disinfection robot includes a housing 1, and the housing 1 specifically includes an upper housing 2 and a lower housing 3. An upper fixing plate 26 is injection-molded on the circumferential outer wall at the lower end of the upper housing 2, and a lower fixing plate 32 is injection-molded on the circumferential outer wall at the upper end of the lower housing 3. A plurality of upper fixing holes are circumferentially formed on the upper fixing plate 26, and a plurality of lower fixing holes are circumferentially formed on the lower fixing plate 32. The upper housing 2 and the lower housing 3 are fixed by sequentially passing bolts through the upper fixing holes and screwing them into the lower fixing holes. Combining Figure 7 , an annular installation groove 321 is circumferentially formed on the upper side plate surface of the lower fixing plate 32. When the upper housing 2 and the lower housing 3 are screwed and fixed, a sealing ring can be embedded in the installation groove 321 to seal the gap between the upper housing 2 and the lower housing 3.

[0037] Combining Figures 3-6 , a vertically arranged mist outlet pipe 14 is injection-molded at the inner top of the upper housing 2. The upper end of the mist outlet pipe 14 protrudes from the outer wall at the upper end of the upper housing 2, and the lower end extends into the lower housing 3 when the upper housing 2 and the lower housing 3 are fixed together. The lower end of the mist outlet pipe 14 is the mist inlet 141, the upper end is the mist outlet, and a plurality of air inlets 142 are circumferentially formed on the outer side wall of the mist outlet pipe 14. Each air inlet 142 is in a strip shape. The lower end of each air inlet 142 extends to the lower edge of the lower end of the mist outlet pipe 14, and the upper end extends to the forming part of the inner wall at the upper end of the mist outlet pipe 14 and the upper housing 2. A ventilation pipe 12 is injection-molded on the inner bottom wall of the lower housing 3. The lower end port of the ventilation pipe 12 is communicated with the outside, and a ventilation opening 121 communicated with the internal cavity of the housing 1 is formed on the outer side wall at the upper end. An installation opening 31 is formed on the inner bottom wall of the lower housing 3 below the mist outlet pipe 14. A fan 13 is fixed at the lower end port of the ventilation pipe 12 at the bottom of the lower housing 3 by screwing, clamping, etc. And when the upper housing 2 and the lower housing 3 are fixed together, the upper end of the ventilation pipe 12 extends into the upper housing 2, so that the height of the ventilation opening 121 of the ventilation pipe 12 is the same as that of the mist inlet 141 at the bottom of the mist outlet pipe 14. An installation opening 31 is embedded with a high-frequency oscillator 11, and the high-frequency oscillator 11 is screwed and fixed to the lower bottom of the lower housing 3 by screws.

[0038] As Figure 2 shown in and Figure 4 shown, a partition plate 21 is provided between the ventilation pipe 12 and the fog outlet pipe 14 inside the upper shell 2, thereby dividing the cavity inside the upper shell 2 into a ventilation cavity 22 containing the ventilation pipe 12 and a fog-forming cavity 23 containing the fog outlet pipe 14. One side of the partition plate 21 is injection-molded with one inner wall of the upper shell 2, and an air passing gap 24 communicating the ventilation cavity 22 and the fog-forming cavity 23 is formed between the other side and the other inner wall of the upper shell 2. Moreover, a diversion gap 4 higher than and lower than the ventilation opening 121 is formed between the partition plate 21 and the inner wall of the lower shell 3. The inner wall of the fog-forming cavity 23 is arc-shaped, and the ventilation opening 121 at the upper end of the ventilation pipe 12 specifically faces the inner side wall of the upper shell 2.

[0039] As Figure 2 shown in and Figure 4 shown, an extension part 25 is injection-molded on the circumferential side wall at the lower end of the upper shell 2. When the upper shell 2 and the lower shell 3 are fixed together, the extension part 25 extends into the lower shell 3 to make the gap between the lower end of the upper shell 2 and the inner bottom wall of the lower shell 3 smaller.

[0040] Working principle: The tap water introduced into the housing 1 is located in the lower shell 3 and submerges the electrode group. The electrode group is energized to continuously electrolyze the tap water to form a mixture of water and ozone (i.e., ozone water). During the disinfection work, the high-frequency oscillator 11 is energized to vibrate to atomize the ozone water in the lower shell 3 into ozone water mist. The ozone water mist continuously diffuses upward and stays in the fog-forming cavity 23. At the same time, the fan 13 works to convert the outside air into a high-speed flowing air current and input it into the ventilation cavity 22 through the ventilation pipe 12. When the air pressure in the ventilation cavity 22 continuously increases, the air current is pressed out through the air passing gap 24 and the diversion gap 4 and flows along the inner wall of the fog-forming cavity 23. In this state, the air current passing through the diversion gap 4 can push the ozone water mist towards the fog inlet 141 at the bottom of the fog outlet pipe 14, and make the ozone water mist enter the fog outlet pipe 14. And the air current passing through the air passing gap 24 enters the fog outlet pipe 14 from the air inlet 142 on the outer circumferential wall of the fog outlet pipe 14. Due to the existence of the flow velocity difference, a strong negative pressure attraction effect can be formed at the fog inlet 141 of the fog outlet pipe 14, so that the ozone water mist in the fog-forming cavity 23 can enter the fog outlet pipe 14 more quickly with low loss and be mixed with the air current. Driven by the subsequent air current, the air current carrying the ozone water mist passes through the fog outlet of the fog outlet pipe 14 and is sprayed outwards by the spray pipe, thereby enabling the disinfection robot to complete the disinfection and sterilization work.

Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0042] Although the terms such as housing 1, high-frequency oscillator 11, ventilation pipe 12, ventilation opening 121, fan 13, fog outlet pipe 14, fog inlet 141, air inlet 142, upper housing 2, partition plate 21, ventilation chamber 22, fog formation chamber 23, air passage gap 24, extension portion 25, upper fixing plate 26, lower housing 3, installation opening 31, lower fixing plate 32, installation groove 321, flow splitting gap 4, etc. are used more frequently in this text, the possibility of using other terms is not excluded.
