[0019] Example 1 like Figure 1 - Figure 3 As shown: This embodiment provides a technical solution: an electrostatic field deodorization device for a cold chain vehicle, comprising a device housing 1, a fan 6, a data acquisition module 9, a data processing module 4 and a control module 2. An air inlet 102 is provided at one end of the device housing 1, and an air outlet 101 is provided at the other end. An ionization electrode plate group 8 and a deposition electrode column 7 are installed inside the device housing 1. The ionization electrode plate group 8 and the deposition electrode column 7 are respectively installed on one side of the device housing 1 close to the air inlet 102 and the side close to the air outlet 101. The ionization electrode plate group 8 and the deposition electrode column 7 are used to generate a high-voltage electric field, so that when the air passes through the ionization electrode plate group 8, the ammonia molecules (the main source of odor) and dust in the air are charged, and when passing through the deposition electrode column 7, the charged ammonia molecules and dust are deposited to achieve the effect of deodorization and dust removal. A fixing plate 103 is provided on one side of the device housing 1 for fixing the device housing 1 to the cold chain vehicle. The fan 6 is installed inside the device housing 1 to change the air flow speed inside the device housing 1. The data acquisition module 9 is installed inside the device shell 1, and is used to collect data information of the deposition electrode column 7. The data processing module 4 is installed on the device shell 1, and generates a speed control coefficient according to the collected data information. The control module 2 is installed on the device shell 1, and is used to control the speed of the fan 6 according to the speed control coefficient. The deodorization device collects data information of the deposition electrode column 7 inside the device shell 1 through the data acquisition module 9, and can analyze and obtain changes in the deodorization device during use. According to the changes, the speed required by the current fan 6 can be deduced. Therefore, the deodorization device can achieve dust removal and deodorization with optimal power, and has excellent energy-saving effect.

[0020] The present embodiment provides an electrostatic field deodorization device for a cold chain vehicle. Specifically, the data information includes: an initial diameter of the deposition electrode column 7, a height of the deposition electrode column 7, and image data of the deposition electrode column 7, wherein the initial diameter of the deposition electrode column 7 and the height of the deposition electrode column 7 are directly obtained by measurement before the device is used, and the image data of the deposition electrode column 7 is acquired by a camera installed inside the device housing 1.

The larger the original diameter of the deposition electrode column 7, the easier it is for the ammonia molecules and dust molecules to deposit on the deposition electrode column 7, which is manifested as the smaller the change of the deposition electrode column 7. Therefore, the air flow rate can be appropriately reduced, and the speed requirement for the fan 6 is lower, and vice versa.

[0022] in, is the speed control coefficient, For the The change value of the deposition electrode column 7 during the first acquisition, For the -1 acquisition time, the change value of deposition electrode column 7, is the initial diameter of the deposition electrode column 7, , is the weight factor, , are greater than 0, , The value of is an integer greater than 1, wherein the weight factor is collected by a technician in this field and a corresponding weight factor is set for each set of comprehensive parameters. The set weight factor and the collected comprehensive parameters are substituted into the formula. Any three formulas constitute a three-variable linear equation system. The calculated weight factors are screened and averaged to obtain , The mean of In addition, it should be noted that the size of the weight factor is a specific value obtained by quantifying each data, which is convenient for subsequent comparison. The size of the weight factor depends on the number of comprehensive parameters and the preliminary setting of the corresponding weight factor for each set of comprehensive parameters by those skilled in the art. Optionally, + =1, is 0.41; It is 0.59.

[0023] This embodiment provides an electrostatic field deodorization device for a cold chain vehicle. Specifically, the method in which the control module 2 controls the speed of the fan 6 based on the speed control coefficient is as follows: Speed ​​control coefficient The larger the value, the faster the speed of fan 6 is. The relationship between the speed and the speed is based on a preset relationship, as follows: The preset speed control coefficient threshold is , ,in < ; The preset speed control coefficient threshold is the basis for dividing and generating the first-level speed command, the second-level speed command and the third-level speed command.

[0025] Example 2 like Figure 1 - Figure 3 As shown: This embodiment provides a technical solution: a cold chain vehicle electrostatic field deodorization device, including Figure 1 - Figure 4 As shown, in order to prevent the sediment on the surface of the deposition electrode column 7 from being blown into the outside again after being scattered, in this embodiment, a dust collecting bin 3 with a funnel-shaped structure is installed at the bottom of the device shell 1, and a dust discharge pipe 301 is installed at the bottom of the dust collecting bin 3. Two inclined anti-backflow plates 302 are symmetrically installed at the position of the dust collecting bin 3 inside the device shell 1, so that the falling sediment can directly fall into the dust collecting bin 3 and be collected, and the setting of the anti-backflow plate 302 can prevent the sediment from being sucked back into the air.

[0026] like Figure 4 - Fig.12As shown, in order to ensure the long-term and stable adsorption effect of the deposition electrode column 7, in this embodiment, a cleaning mechanism 5 is installed inside the device shell 1, and the cleaning mechanism 5 is used to regularly clean the surface of the deposition electrode column 7. The cleaning mechanism 5 includes a lifting plate 51 and a driving component, wherein the lifting plate 51 is horizontally installed inside the device shell 1, and a cleaning component 54 is embedded on the lifting plate 51. The cleaning component 54 is sleeved on the deposition electrode column 7, and the driving component is installed inside the device shell 1, and is used to drive the lifting plate 51 to move in the vertical direction. Therefore, when the lifting plate 51 moves in the vertical direction under the drive of the driving component, the cleaning component 54 can move up and down on the surface of the deposition electrode column 7 to clean the surface of the deposition electrode column 7.

[0027] Specifically, the driving assembly includes a screw rod 52, a screw nut 511 and a motor, wherein the screw rod 52 is installed inside the device housing 1 in the vertical direction, the screw nut 511 is embedded in the center position of the lifting plate 51, and the screw rod 52 and the screw nut 511 are adapted and socketed with each other, and the motor is installed on the device housing 1, and the output shaft of the motor is transmission-connected with one end of the screw rod 52, so when the motor is running, it can drive the screw rod 52 to rotate, and under the adaptation of the screw nut 511, the lifting plate 51 moves in the vertical direction.

[0028] like Figure 8 , Fig.11 and Fig.12 As shown, in order to ensure the contact between the cleaning component 54 and the deposition electrode column 7 and improve the cleaning effect, the cleaning component 54 includes a cleaning brush carrier 541 and a movable plate with a brush 5411, wherein the cleaning brush carrier 541 is rotatably embedded and installed on the lifting plate 51 through a bearing, and a mounting cavity 5413 is arranged inside the cleaning brush carrier 541, and the movable plate with a brush 5411 adopts an arc structure and is movably assembled in the mounting cavity 5413, and bristles are arranged on the inner side of the movable plate with a brush 5411, and the bristles of the movable plate with a brush 5411 extend out from the mounting cavity 5413 and squeeze on the deposition electrode column 7, and the movable plate with a brush 5411 is provided with a brush. The plate 5411 is connected to the inner wall of the installation cavity 5413 by an elastic component 5414, and the elastic component 5414 is a spring. Under the elastic force of the elastic component 5414, the bristle side of the movable plate 5411 with a brush can always remain pressed against the surface of the deposition electrode column 7, thereby ensuring the cleaning effect of the cleaning component 54 during cleaning. Specifically, the installation cavity 5413 is a circular ring structure, and each installation cavity 5413 is correspondingly provided with a plurality of movable plates 5411 with brushes, and gaps are left between adjacent movable plates 5411 with brushes to ensure that the movable plates 5411 with brushes can move.

[0029] like Fig.12As shown, in order to prevent the movable plate 5411 with a brush from being squeezed too hard and affecting the overall movement of the cleaning component 54, a convex plate 5412 is provided at the bottom of the movable plate 5411 with a brush, and a limiting groove 5415 is radially opened at the bottom of the mounting cavity 5413. The convex plate 5412 slides and engages in the limiting groove 5415. In this way, the movement of the movable plate 5411 with a brush can be controlled within a suitable space, thereby ensuring both the cleaning effect and smooth cleaning.

[0030] like Figure 5 , Figure 7 and Figure 8 As shown, in order to ensure that the cleaning effect of the cleaning component 54 on the deposition electrode column 7 is further improved, in this embodiment, the cleaning component 54 also includes a guiding rotating part 542, which is installed above the cleaning brush carrier 541 and sleeved on the deposition electrode column 7. A combined sphere 543 is provided on the inner side of the guiding rotating part 542. A spiral groove 701 is provided on the surface of the deposition electrode column 7. The spiral groove 701 is opened from top to bottom around the surface of the deposition electrode column 7. The combined sphere 543 rolls and engages in the spiral groove 701. Such a structural setting enables the combined sphere 543 to roll along the trajectory of the spiral groove 701 when the lifting plate 51 is lifted or lowered, so that the cleaning component 54 can keep rotating while lifting or lowering, and this rotation does not require an external power structure to drive it, which is not only energy-saving, but also can reduce the actual production cost of the equipment. At the same time, this lifting + rotating cleaning method can significantly improve the cleaning effect of the cleaning component 54 on the surface of the deposition electrode column 7. Specifically, there is a certain gap between the guiding rotating part 542 and the deposition electrode column 7.

[0031] In order to prevent ammonia molecules and dust from being deposited in the spiral groove 701 when the deposition electrode column 7 is actually in use, thereby affecting the movement of the combined sphere 543, in this embodiment, a layer of material made of a non-deposition electrode column 7 (such as plastic material, etc.) is embedded in the inner wall of the spiral groove 701. This can reduce the deposition of ammonia molecules and dust in the spiral groove 701 and ensure that the combined sphere 543 can move normally (a small amount of deposition will not affect the movement of the combined sphere 543, and it can also be removed at the same time when the cleaning component 54 is cleaning).

[0032] like Fig. 9 and Fig.10As shown, in order to ensure that the combined sphere 543 moves more smoothly in the spiral groove 701 and makes the rotation of the cleaning component 54 more stable, in this embodiment, snap-fit ​​grooves 7011 are opened above and below the inner wall of the spiral groove 701, and the combined sphere 543 includes a main sphere 5432 and an auxiliary sphere 5433 rotatably embedded above and below the main sphere 5432, and the auxiliary sphere 5433 rolls and engages in the snap-fit ​​groove 7011, and the main sphere 5432 is fixedly connected to the guide rotating part 542 by the connecting part 5431, so that the main sphere 5432 can control and maintain the rotation stability of the cleaning component 54, and the upper and lower auxiliary spheres 5433 can assist the sliding of the combined sphere 543, thereby stabilizing the entire cleaning component 54 during the cleaning process.

[0033] like Figure 5 and Figure 6 As shown, in order to improve the stability of the entire lifting plate 51 when moving, in this embodiment, sliding sleeves 512 are embedded and installed at both ends of the lifting plate 51, and a limiting slide rod 53 is installed in the vertical direction inside the device shell 1. The slide rod 53 is slidably connected with the sliding sleeve 512. In this way, when the lifting plate 51 moves, the movement is more stable under the limiting action of the slide rod 53 and the sliding sleeve 512.

However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
