[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail in conjunction with the accompanying drawings and embodiments below; in the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shape, thickness or height of each component can be enlarged or reduced. The various embodiments listed in the utility model are only used to illustrate the utility model, and are not used to limit the scope of the utility model. Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1-Figure 4 As shown, an automatic disinfectant adding device for a central air-conditioning condensate tray provided by the utility model comprises a disinfectant tank 21, a liquid supply pump 22 connected to the disinfectant tank 21, a liquid adding pipe 3 rotatably mounted on the condensate tray 1, and a driving mechanism 23 for driving the liquid adding pipe 3 to reciprocate around its axis at a set angle. In specific settings, the driving mechanism 23 is set as a servo motor, the output end of the servo motor is coaxially fixed with a main gear, the outer periphery of the liquid adding pipe 3 is fixed with a gear ring meshing with the main gear, and a hose is connected between the output end of the liquid supply pump 22 and the liquid adding pipe 3. The liquid adding pipe 3 is arranged along the length direction of the condensate pipe, and a plurality of liquid spraying slits 31 are provided on the peripheral wall of the liquid adding pipe 3 close to the condensate tray 1, and the plurality of liquid spraying slits 31 are arranged at intervals along the length direction of the liquid adding pipe 3.

[0031] In this way, when the condensate water tray 1 needs to be disinfected, the liquid supply pump 22 and the servo motor can be started. When the liquid supply pump 22 is started, the disinfectant in the disinfectant tank 21 is pumped into the liquid adding pipe 3 and sprayed from the multiple liquid spraying slots 31, so that the disinfectant can be automatically added to the condensate water tray 1; and when the servo motor is started, the liquid adding pipe 3 is driven to swing back and forth so that the disinfectant sprayed from the liquid spraying slots 31 is evenly distributed in the width direction of the condensate water tray 1, so that with the help of the setting of multiple liquid spraying slots 31, the condensate water tray 1 can be fully and automatically added with disinfectant, which can ensure the disinfection effect of the disinfectant on the condensate water tray 1. The overall structure occupies a small space, and the adding device of the present application can be conveniently installed between the air outlet of the air conditioner and the condensate water tray 1, which can reduce the difficulty of modifying the existing ventilation system of the hospital and is suitable for practical use.

[0032] Specifically, refer to Figure 2 and Figure 3 The liquid spraying slot 31 is expanded from the inside to the outside in the wall thickness direction of the liquid adding pipe 3, and the liquid curtains sprayed from two adjacent liquid spraying slots 31 have overlapping parts between the splashing areas on the condensate water tray 1. In this way, the expanded spraying slot setting can cover the condensate water tray 1 as comprehensively as possible with fewer spraying slots, so as to ensure the comprehensive disinfection effect of the condensate water tray 1 as much as possible.

[0033] Furthermore, in order to prevent the spraying seams with smaller seam width from being blocked by dust particles due to long-term exposure to the air when not disinfected, refer to Figure 3 and Figure 4 A sleeve 4 is disposed on the outer sleeve of the liquid adding pipe 3, and a plurality of notches 41 corresponding to the plurality of liquid spraying slits 31 are opened on the sleeve 4, and the notches 41 are arranged circumferentially around the sleeve 4. The condensate water tray 1 is provided with an adjusting mechanism for driving the sleeve 4 to expose the liquid spraying slit 31 when the liquid adding pipe 3 is in a liquid adding state and to close the liquid spraying slit 31 when the liquid adding pipe 3 stops adding liquid.

[0034] Specifically, the adjustment mechanism includes a mounting seat 5 fixedly connected to the condensed water tray 1, the liquid adding pipe 3 rotates and penetrates the mounting seat 5, the sleeve 4 is slidably arranged on the mounting seat 5 along its length direction, and a straight groove 42 and an inclined groove 43 along its circumference are opened on the inner peripheral wall of the sleeve 4, the straight groove 42 and the inclined groove 43 are connected, and the inclined groove 43 is inclined toward the axial direction of the sleeve 4, and a control column 32 that is slidably adapted to both the straight groove 42 and the inclined groove 43 is fixedly connected to the outer peripheral wall of the liquid adding pipe 3;

[0035] When the liquid adding pipe 3 is in the liquid adding state, the servo motor drives the liquid adding pipe 3 to reciprocate at an angle covering the width of the condensed water tray 1, thereby driving the control column 32 to slide reciprocally in the straight groove 42;

[0036] When the liquid adding pipe 3 stops adding liquid, the servo motor drives the liquid adding pipe 3 to rotate to the stop position. At this time, the control column 32 is located at the end of the inclined groove 43 away from the straight groove 42, and the sleeve 4 moves to close the multiple liquid spraying slots 31.

[0037] In this way, when the servo motor drives the adding tube 3 to rotate reciprocatingly, the control column 32 on the adding tube 3 slides reciprocatingly in the straight groove 42 on the sleeve 4. At this time, the liquid injection slit 31 on the adding tube 3 is always exposed in the corresponding notch 41 on the sleeve 4, and the adding tube 3 can be maintained in the liquid injection state; and when the servo motor drives the adding tube 3 to rotate to the stop position, the control column 32 slides in the inclined groove 43 on the sleeve 4 and then pushes the sleeve 4 to move axially along the adding tube 3 on the mounting seat 5 until the sleeve 4 as a whole closes multiple liquid injection slits 31 at the same time, so that the liquid injection slit 31 can be effectively and automatically protected without setting up additional complex mechanisms.

[0038] In addition, when the liquid adding pipe 3 retracts to the parking position, the sleeve 4 moves axially relative to the liquid adding pipe 3, which can effectively scrape the area around the spraying seam on the liquid adding pipe 3, and can also clean the expanded spraying seam 31 to a certain extent, while effectively ensuring that the liquid adding pipe 3 remains in a straight state.

[0039] In order to achieve the sliding effect of the sleeve 4 on the mounting seat 5, refer to Figure 2 and Figure 4 At least two limit rods 44 penetrating the mounting seat 5 are fixedly connected to one end of the sleeve 4 close to the mounting seat 5 , so that the limit rods 44 can limit the movement trajectory of the sleeve 4 to ensure the relative movement effect between the sleeve 4 and the liquid adding tube 3 .

[0040] Embodiment 2:

[0041] The difference between this embodiment and the first embodiment is that:

[0042] In order to ensure that the amount of disinfectant added by the longer liquid adding pipe 3 at various locations in the condensate water tray 1 is as consistent as possible, the length of the multiple liquid spraying slots 31 gradually increases along the liquid adding pipe 3 from the end close to the liquid supply pump 22 to the end far away from the liquid supply pump 22, so as to prevent the liquid adding pressure at the far end of the liquid adding pipe 3 from being reduced, resulting in a reduction in the amount of liquid added.

[0043] The specific working effects of the utility model are as follows:

[0044] When the entire device is in use, when the condensate water tray 1 needs to be disinfected, the liquid supply pump 22 and the servo motor can be started. When the liquid supply pump 22 is started, the disinfectant in the disinfectant tank 21 is pumped into the liquid adding pipe 3 and sprayed from the multiple liquid spraying slots 31, so that the disinfectant can be automatically added to the condensate water tray 1; and when the servo motor is started, the liquid adding pipe 3 is driven to swing back and forth so that the disinfectant sprayed from the liquid spraying slots 31 is evenly distributed in the width direction of the condensate water tray 1, so that with the help of the setting of multiple liquid spraying slots 31, the condensate water tray 1 can be fully and automatically added with disinfectant, which can ensure the disinfection effect of the disinfectant on the condensate water tray 1. The overall structure occupies a small space, and the adding device of the present application can be conveniently installed between the air outlet of the air conditioner and the condensate water tray 1, which can reduce the difficulty of modifying the existing ventilation system of the hospital and is suitable for actual use.
