[0019] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0020] This embodiment provides an automatic shaking spray generating device for aerosol chemicals.

[0021] Reference Figure 1 , Figure 2 , an automatic shaking spray generating device for aerosol chemicals, comprising a frame 1, a fixing device 2, a shaking device 3, a trigger device 4 and a gas buffer device 5.

[0022] The frame 1 is used to carry the fixing device 2, the shaking device 3, the trigger device 4 and the gas buffer device 5. The fixing device 2 is used to carry and fix the aerosol chemical. The shaking device 3 is used to drive the fixing device 2 to shake. The trigger device 4 is used to press the aerosol chemical button switch after the shaking action to generate aerosol. The gas buffer device 5 buffers and collects the aerosol generated by the aerosol chemical.

The fixing frame 21 includes a fixing plate 211 arranged vertically and a tray 212 arranged horizontally at the lower end of the fixing plate 211. The tray 212 is used to support the bottom of the aerosol chemical bottle. The buffer block 22 is provided with at least one arc groove 221 arranged on the inner side of the fixing plate 211 and adapted to the shape of the aerosol chemical bottle. The arc groove 221 is provided for the aerosol chemical bottle to be embedded and abutted. The tying assembly 23 is used to tie and fix the aerosol chemical bottle. The fixing plate 211 is also provided with an auxiliary ring 24 located above the tray 212 for the aerosol chemical bottle to pass vertically, so as to cooperate with the tray 212, the buffer block 22 and the tying assembly 23 to stably install the aerosol chemical on the fixing plate 211.

[0024] The binding component 23 can be an elastic cloth strip, a rubber strip, a Velcro strip, etc. A plurality of hanging rings are provided on both sides of the upper end of the fixing plate 211, and the hanging rings on both sides are symmetrically arranged. The elastic cloth strip, the rubber strip, the Velcro strip, etc. can pass through the hanging rings to bind and fix the aerosol chemicals.

[0025] In order to adapt to the fixing needs of aerosol chemical bottles of different heights and diameters, the buffer block 22, the auxiliary ring 24 and the fixing plate 211 are detachably connected, and the tray 212 can be adjusted and fixed along the height direction of the fixing plate 211. The buffer block 22, the auxiliary ring 24 and the fixing plate 211 can be connected and fixed by means of screws, clamping, etc., so as to replace the buffer block 22 adapted to the diameter of the aerosol chemical bottle; the tray 212 can be adjusted in height by screws and threaded holes arranged along the height direction of the fixing plate 211, or by L-shaped clamping blocks and slots, etc., so as to adapt to the bearing needs of aerosol chemical bottles of different heights.

[0026] Reference Figure 4 , Figure 5 The shaking device 3 includes a motor 31, an eccentric crank 32, a connecting rod 33 and a guide frame 34. The eccentric crank 32 includes a counterweight block 321 arranged in a semicircular shape and a connecting column 322 arranged on the counterweight block 321. The connecting column 322 is eccentrically arranged with respect to the counterweight block 321 (the center of the circle of the counterweight block 321 is defined as the center of the eccentric crank 32 in the embodiment of the present application), so that when the eccentric crank 32 rotates, the counterweight block 321 offsets the inertia force generated by the fixing device 2 connected to the connecting column 322, thereby reducing the vibration generated during shaking.

[0027] The driving shaft of the motor 31 is connected to the center of the eccentric crank 32. One end of the connecting rod 33 is rotatably connected to the connecting column 322, and the other end is rotatably connected to the fixed plate 211. The guide frame 34 is arranged above the connecting rod 33, and a guide rod 341 is vertically arranged on the guide frame 34. A guide slider 2111 is arranged on the side of the fixed plate 211 away from the side for fixing the aerosol chemical. The guide slider 2111 can slide vertically along the guide rod 341, and when the motor 31 drives the eccentric crank 32 to move, the eccentric crank 32 drives the fixed plate 211 to make vertical reciprocating motion through the connecting rod 33, so as to realize the oscillation operation of the aerosol chemical on the fixed plate 211.

[0028] In order to avoid excessive load on the drive shaft of the motor 31 during the transmission process, a pulley mechanism 6 is provided between the motor 31 and the eccentric crank 32, and the pulley mechanism 6 includes a driving pulley and a driven pulley. The driving pulley and the driven pulley are driven by synchronous connection, and the driving pulley is connected to the motor 31, and the driven pulley is connected to the center of the eccentric crank 32 through the main shaft. At the same time, in order to increase the impact load that the connecting shaft (including the connecting column 322) can bear during the movement of the connecting rod 33, the connecting column 322, and the fixed plate 211, the connecting rod 33, the connecting column 322, and the fixed plate 211 are all provided with double bearings.

[0029] Reference Figure 2 , Figure 6 The trigger device 4 includes a pressing cylinder 41, which is arranged above the fixing plate 211 and is used to press the aerosol chemical button switch.

[0030] In order to adapt to the pressing requirements of aerosol chemicals with different bottle diameters, the trigger device 4 further includes a position adjustment component 42, which is used to adjust the position of the pressing cylinder 41 along the horizontal direction.

[0031] The position adjustment assembly 42 includes a lower bracket 421 and an upper bracket 422. The lower bracket 421 is horizontally arranged on the top of the guide frame 34, and the upper bracket 422 is vertically arranged and used to carry the pressing cylinder 41. The upper bracket 422 can be horizontally slid and fixed along the lower bracket 421. The specific arrangement method is: the upper end face of the lower bracket 421 is threadedly connected with a plurality of bolts, and the lower end face of the upper bracket 422 is provided with a plurality of sliding grooves along its length direction for the bolts to slide correspondingly.

[0032] Reference Figure 2 The gas buffer device 5 includes a buffer tank 51 and a support frame 52. The support frame 52 is vertically arranged at the front side of the fixing frame 21, and the buffer tank 51 is horizontally arranged at the top of the fixing frame 21 and is used to connect the nozzle of the aerosol chemical to buffer and collect the aerosol generated by the aerosol chemical when the trigger device 4 is working.

[0033] In order to facilitate the installation and fixation of aerosol chemicals on the fixing device 2, the support frame 52 includes a base 521 and a bracket 522. The bracket 522 is vertically arranged on the top of the base 521, and the bracket 522 and the base 521 are arranged opposite to each other at one end. The pair of inclined surfaces are adapted to each other, and the inclined surface connection is fixed by bolts.

[0034] At the same time, in order to adapt to the installation requirements of aerosol chemicals with different bottle diameters, the base 521 can be slidably fixed along the frame 1 to adjust the distance between the support frame 52 and the fixing frame 21.
