Description

Technical Field

[0001] This utility model relates to the field of disinfection robot technology, specifically a disinfection robot with an automatic liquid dispensing component. Background Technology

[0002] In wards treating infectious diseases and similar settings require regular disinfection. To avoid infection of medical staff, existing technologies have proposed using disinfection robots for automated disinfection. Specifically, the disinfection robot carries a storage tank for temporarily storing disinfectant. A disinfection pump draws the disinfectant from the storage tank to nozzles, which then spray it into the ward. Combined with the robot's movement, this achieves disinfection of the entire ward.

[0003] However, during the disinfection process of the disinfection robot, due to the limited volume of the storage tank, staff need to constantly monitor the remaining amount of disinfectant in the tank and add disinfectant in a timely manner to ensure the normal operation of the disinfection robot. Adding disinfectant to the disinfection robot in the above way will consume a lot of manpower, especially when continuous disinfection is required at night. If there are no staff on duty at night, the disinfection robot will be interrupted and continuous disinfection will not be possible.

[0004] For example, the automatic liquid dispensing device for a spray disinfection robot disclosed in Chinese Patent CN218596107U has a moving mechanism installed at the bottom of the automatic liquid dispensing device. The moving mechanism enables the entire automatic liquid dispensing device to move. A dispensing head is installed at one end of the liquid storage tank. The dispensing head is in contact with the injection head on the liquid storage device. The injection head squeezes the seal inside the dispensing head. The seal is opened under the action of a spring, so that the injection head enters the interior of the dispensing head. Then, the main controller controls the opening of the first control valve and the second control valve to realize the automatic liquid dispensing function.

[0005] The device uses a pressure pump to draw disinfectant from the storage tank for spraying. If there are sediments or undissolved particles in the disinfectant, they may be sucked into the pressure pump, causing it to become clogged and preventing the disinfection process from continuing.

[0006] Therefore, we urgently need to provide a disinfection robot with filtration function and an automatic liquid dispensing component. Utility Model Content

[0007] The purpose of this invention is to provide a disinfection robot with an automatic liquid dispensing component, in order to solve the problem mentioned in the background art that if there are precipitates or undissolved particles in the disinfectant solution, they may be sucked into the pressure pump, causing the pressure pump to become clogged and preventing the disinfection work from continuing normally.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a disinfection robot with an automatic liquid dispensing component, comprising a base and casters. The casters are installed at the four lower corners of the base. A liquid storage tank is fixedly connected to the upper end of the base. A mist outlet pipe is fixedly connected to the upper end of the liquid storage tank. A nozzle is installed at the upper end of the mist outlet pipe with an equal arc. A pressure pump is installed at the bottom of the inside of the liquid storage tank. A connecting pipe is fixedly connected to the outer end of the pressure pump. The upper end of the connecting pipe is fixedly connected to the lower end of the mist outlet pipe. A liquid dispensing mechanism is provided at both the inner and outer ends of the liquid storage tank. The liquid dispensing mechanism includes a filtration unit and a switching unit. The filtration unit is located at the outer end of the liquid storage tank, and the switching unit is located at both the inner and outer ends of the liquid storage tank.

[0009] The filtration unit includes a filter tube fixedly connected to the upper left end of the storage tank. A solenoid valve is installed at the left end of the filter tube, and a liquid filling pipe is installed at the left end of the solenoid valve. The other end of the liquid filling pipe is connected to a disinfectant supply device. A filter screen is fixedly connected to the middle of the inner side of the filter tube. A threaded rod is fixedly connected to the lower outer side of the filter tube. An arc-shaped sealing plate is connected to the outer end of the threaded rod, and a retaining ring is connected to the outer end of the threaded rod.

[0010] A further improvement is that the arc-shaped sealing plate has round holes at both the left and right ends, the inner side of the fixing ring has an internal thread, the outer side of the threaded rod is threaded to the inner side of the fixing ring, the outer side of the threaded rod is slidably connected to the inner side of the round hole, the lower outer end of the filter tube abuts against the upper side of the arc-shaped sealing plate, and the round hole of the arc-shaped sealing plate abuts against the upper side of the fixing ring. Thus, after the arc-shaped sealing plate is placed on the lower outer end of the filter tube and the threaded rod passes through the round hole, the fixing ring is threaded to the outer side of the threaded rod, and the upper side of the fixing ring contacts the lower side of the arc-shaped sealing plate, so that the arc-shaped sealing plate can be fixed to the lower outer end of the filter tube.

[0011] A further improvement is that a through groove is provided at the lower end of the filter tube below the filter screen, and a threaded rod is fixed to the left and right ends of the through groove on the lower side of the filter tube. When the arc-shaped sealing plate is fixed to the lower side of the filter tube, the arc-shaped sealing plate will close the through groove.

[0012] A further improvement is that a rubber pad is fixedly connected to the upper side of the arc-shaped sealing plate. When the arc-shaped sealing plate is fixed to the lower outer side of the filter tube, the rubber pad on the upper side of the arc-shaped sealing plate contacts the outer side of the filter tube, which keeps the contact between the arc-shaped sealing plate and the filter tube sealed.

[0013] A further improvement is that the switch unit is fixedly connected to the limiting rods at both the front and rear ends inside the liquid storage tank. A float plate is connected to the outer end of the limiting rod. A first electrical contact is installed on the upper side of the float plate. A second electrical contact is installed at the top of the inner side of the liquid storage tank above the first electrical contact. A moving rod is fixedly connected to the upper right end of the float plate. A connecting plate is fixedly connected to the upper end of the moving rod. A third electrical contact is installed on the lower side of the connecting plate. A fourth electrical contact is installed on the upper side of the liquid storage tank below the third electrical contact.

[0014] A further improvement is that limit holes are opened at both the front and rear ends inside the float, and the outer side of the limit rod is slidably connected to the inner side of the limit hole, so that when the height of the float changes, it can only slide along the outer side of the limit rod.

[0015] A further improvement is that a sliding hole is provided on the upper right side of the inside of the liquid storage tank, and the outer side of the moving rod is slidably connected to the inner side of the sliding hole.

[0016] A further improvement is that the first and second electrical contacts, or the third and fourth electrical contacts, are in contact to control the opening and closing of the solenoid valve. Thus, when the disinfectant in the storage tank is almost used up, the moving rod follows the float down until the third electrical contact moves down to contact the second electrical contact, controlling the solenoid valve to open. At this time, the disinfectant in the filling pipe enters the interior of the storage tank through the solenoid valve and the filter pipe.

[0017] In summary, this application discloses a disinfection robot with an automatic liquid dispensing component.

[0018] In this technical solution, when the disinfectant solution in the filling tube enters the storage tank through the solenoid valve and the filter tube, it is filtered by the filter screen in the filter tube. This ensures that any sediment or undissolved particles are filtered out and retained in the filter tube, guaranteeing that the disinfectant solution drawn by the pressure pump into the storage tank is free of sediment or undissolved particles. This protects the working safety of the pressure pump and ensures the normal operation of the disinfection process. Furthermore, by rotating the fixing ring and removing it from the outside of the threaded rod, and then removing the outer end of the threaded rod in the arc-shaped sealing plate, the sediment or undissolved particles on the left side of the filter screen in the filter tube can be cleaned through the through groove, ensuring the filtration effect of the subsequent filter screen.

[0019] Furthermore, when the disinfectant in the storage tank is almost used up, the moving rod follows the float downwards until the third electrical contact moves down to contact the second electrical contact. At this time, the solenoid valve is opened, and the disinfectant in the filling tube enters the storage tank through the solenoid valve and the filter tube. During the filling process, the float rises with the liquid level until it moves the first electrical contact up to contact the second electrical contact at the top. At this time, the solenoid valve is closed, and no more disinfectant enters the storage tank. This completes one filling of the disinfectant in the storage tank, thus realizing the automatic filling function of disinfectant. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a disinfection robot with an automatic liquid dispensing component, including a base 1 and casters 2. The casters 2 are installed at the four lower corners of the base 1. A liquid storage tank 3 is fixedly connected to the upper end of the base 1. A mist outlet pipe 4 is fixedly connected to the upper end of the liquid storage tank 3. A nozzle 5 is installed at the upper end of the mist outlet pipe 4 with an equal arc. A pressure pump 6 is installed at the bottom inside the liquid storage tank 3. A connecting pipe 7 is fixedly connected to the outer end of the pressure pump 6. The upper end of the connecting pipe 7 is fixedly connected to the lower end of the mist outlet pipe 4. A liquid dispensing mechanism is provided at both the inner and outer ends of the liquid storage tank 3. The liquid dispensing mechanism includes a filter unit and a switch unit. The filter unit is located at the outer end of the liquid storage tank 3, and the switch unit is located at both the inner and outer ends of the liquid storage tank 3.

[0028] The filtration unit includes a filter tube 803 fixedly connected to the upper left end of the liquid storage tank 3. A solenoid valve 802 is installed at the left end of the filter tube 803. A liquid filling pipe 801 is installed at the left end of the solenoid valve 802. The other end of the liquid filling pipe 801 is connected to a disinfectant supply device. A filter screen 804 is fixedly connected to the middle of the inner side of the filter tube 803. A threaded rod 805 is fixedly connected to the lower outer side of the filter tube 803. An arc-shaped sealing plate 806 is connected to the outer end of the threaded rod 805. A retaining ring 807 is connected to the outer end of the threaded rod 805.

[0029] The arc-shaped sealing plate 806 has round holes at both its left and right ends. The inner side of the fixing ring 807 has an internal thread. The outer side of the threaded rod 805 is threaded to the inner side of the fixing ring 807. The outer side of the threaded rod 805 is slidably connected to the inner side of the round hole. The lower outer end of the filter tube 803 abuts against the upper side of the arc-shaped sealing plate 806. The round hole of the arc-shaped sealing plate 806 abuts against the upper side of the fixing ring 807. Thus, after the arc-shaped sealing plate 806 is placed on the lower outer side of the filter tube 803 and the threaded rod 805 passes through the round hole, the fixing ring 807 is threaded to the outer side of the threaded rod 805. After the upper side of the fixing ring 807 contacts the lower side of the arc-shaped sealing plate 806, the arc-shaped sealing plate 806 can be fixed to the lower outer side of the filter tube 803.

[0030] A through groove is provided at the lower end of the filter tube 803 below the filter screen 804. The threaded rod 805 is fixed to the lower outer side of the filter tube 803 at the left and right ends of the through groove. Thus, when the arc-shaped sealing plate 806 is fixed to the lower outer side of the filter tube 803, the arc-shaped sealing plate 806 will close the through groove.

[0031] A rubber pad is fixedly connected to the upper side of the arc-shaped sealing plate 806. When the arc-shaped sealing plate 806 is fixed to the lower outer side of the filter tube 803, the rubber pad on the upper side of the arc-shaped sealing plate 806 contacts the outer side of the filter tube 803, which keeps the contact point between the arc-shaped sealing plate 806 and the filter tube 803 sealed. This prevents the disinfectant from leaking out from the contact point between the filter tube 803 and the arc-shaped sealing plate 806 when it passes through the through groove inside the filter tube 803.

[0032] The switch unit is fixedly connected to the limiting rods 901 at both the front and rear ends inside the liquid storage tank 3. The outer end of the limiting rod 901 is connected to the float plate 902. Limiting holes are opened at both the front and rear ends inside the float plate 902. The outer side of the limiting rod 901 is slidably connected to the inner side of the limiting hole. Thus, when the height of the disinfectant liquid inside the liquid storage tank 3 changes, the float plate 902 can only slide along the outer side of the limiting rod 901, thereby limiting the movement of the float plate 902.

[0033] A first electrical contact 903 is installed on the upper side of the float plate 902. A second electrical contact 904 is installed on the top inner side of the liquid storage tank 3 above the first electrical contact 903. A moving rod 905 is fixedly connected to the upper right end of the float plate 902. A sliding hole is opened on the upper right side of the inside of the liquid storage tank 3. The outer side of the moving rod 905 is slidably connected to the inner side of the sliding hole.

[0034] A connecting plate 906 is fixedly connected to the upper end of the moving rod 905. A third electrical contact 907 is installed on the lower side of the connecting plate 906. A fourth electrical contact 908 is installed on the upper side of the storage tank 3, below the third electrical contact 907. The first electrical contact 903 and the second electrical contact 904, or the third electrical contact 907 and the fourth electrical contact 908, are in contact to control the opening and closing of the solenoid valve 802. Thus, when the disinfectant in the storage tank 3 is almost used up, the moving rod 905 follows the float 902 downwards until the third electrical contact 907 is reached. When the first contact 903 moves down to contact the second electrical contact 904, the control solenoid valve 802 opens. At this time, the disinfectant in the liquid addition pipe 801 enters the interior of the storage tank 3 through the solenoid valve 802 and the filter pipe 803. During the addition process, the float 902 rises with the liquid level until it drives the first electrical contact 903 to move up to contact the second electrical contact 904 at the top. Then, the control solenoid valve 802 closes, and the disinfectant no longer enters the storage tank 3, completing one addition of disinfectant to the storage tank 3, thereby realizing the automatic addition function of disinfectant.

[0035] Working principle: During disinfection, the pressurizing pump 6 is activated to draw the disinfectant solution in the storage tank 3 through the connecting pipe 7 into the mist outlet pipe 4. After being atomized by the mist outlet pipe 4, it is sprayed outwards from the nozzle 5 at the top for disinfection. When the disinfectant solution in the storage tank 3 is about to run out, the float 902 will move down to the bottom of the storage tank 3. At the same time, the third electrical contact 907 at the top moves down to contact the fourth electrical contact 908, causing the solenoid valve 802 to open. The disinfectant solution in the liquid addition pipe 801 is added to the storage tank 3 through the solenoid valve 802 and the filter pipe 803. When it passes through the filter pipe 803, it is filtered by the filter screen 804. At the same time, the float 902 rises with the liquid level until it drives the first electrical contact 903 to move up to contact the second electrical contact 904 at the top. Then, the solenoid valve 802 is closed, and the disinfectant solution no longer enters the storage tank 3, completing the addition of disinfectant solution to the storage tank 3.
