[0044] As Figures 1 to 12As shown in the figure, an installation structure of a vacuum device includes a base 1 and a vacuum device 2 detachably installed on the base 1. A plug head is provided at the bottom of the vacuum device 2, and the base 1 is provided with a socket that cooperates with the plug head. The plug head and the socket are plugged together to realize the connection between the vacuum device 2 and the base 1. A latch 3 that locks and cooperates with the plug head is slidably provided in the base 1, and the latch 3 can slide relative to the base 1 between a first position and a second position. When the latch 3 is in the first position, the latch 3 locks the plug head, so that the vacuum device 2 is fixedly connected to the base 1. When the latch 3 is in the second position, the latch 3 releases the locking of the plug head, so that the vacuum device 2 is disconnected from the fixed connection with the base 1.

[0045] Based on the above embodiments, what the present utility model wants to solve is to provide an installation structure of a vacuum device, including a base 1 and a vacuum device 2 detachably installed on the base 1. When the vacuum device 2 fails and needs to be repaired or replaced, the vacuum device 2 can be removed from the base 1 for repair or replacement without disassembling the base 1 together. A plug head is provided at the bottom of the vacuum device 2, and the base 1 is provided with a socket that cooperates with the plug head. The plug head and the socket are plugged together to realize the connection between the vacuum device 2 and the base 1. A latch 3 that locks and cooperates with the plug head is slidably provided in the base 1, and the latch 3 can slide relative to the base 1 between a first position and a second position of the base 1. When the latch 3 is in the first position, the latch 3 locks the plug head, so that the vacuum device 2 is fixedly connected to the base 1. When the latch 3 is in the second position, the latch 3 releases the locking of the plug head, so that the vacuum device 2 is disconnected from the fixed connection with the base 1. By pulling the latch 3, the locking and unlocking of the vacuum device 2 and the base 1 can be realized, so that when the vacuum device 2 is installed on the base 1, the installation structure is simple, the installation efficiency is high, and no other tools are required.

[0046] As another preferred embodiment of the present utility model, the plug head includes a first plug head 21 located in the middle of the bottom of the vacuum device 2. The socket includes a first socket 11 corresponding to the first plug head 21. A locking groove 211 is provided on the side of the bottom of the first plug head 21 along the sliding direction of the locking bolt 3. The locking bolt 3 is provided with a first locking port 31 that is in locking cooperation with the locking groove 211. There are two locking grooves 211, and the two locking grooves 211 are arranged on both sides of the first plug head 21. The first locking port 31 includes a large mouth end 311 for the first plug head 21 to enter and a small mouth end 312 that is in locking cooperation with the locking groove 211, and the large mouth end 311 is communicated with the small mouth end 312. A handle 35 is provided at the front end of the locking bolt 3. The plug head further includes a second plug head 22 located at the front end of the bottom of the vacuum device 2. The second plug head 22 is provided with a locking buckle 221, and the locking bolt 3 is provided with a second locking port 32 that is in locking cooperation with the locking buckle 221. The second plug head 22 is provided with two locking buckles 221 that cooperate with the second locking port 32. Both of the two locking buckles 221 extend forward relative to the second plug head 22. A gap 2211 for the deformation of the locking buckle 221 is formed between the two locking buckles 221. Raised portions 2212 are provided on the opposite surfaces of the two locking buckles 221, and the raised portions 2212 are provided with a guiding inclined surface 2213 and a locking inclined surface 2214 that respectively cooperate with the second locking port 32. The plug head further includes a third plug head 23 located at the rear end of the bottom of the vacuum device 2. The socket includes a second socket 12 corresponding to the third plug head 23. A third locking port 231 is provided on the side wall of the bottom of the third plug head 23, and the locking bolt 3 is provided with a locking tongue 33 that is in locking cooperation with the third locking port 231. An avoidance opening 222 for the locking bolt 3 to pass through is provided at the bottom of the second plug head 22.

[0047] In this embodiment, as Figures 5 to 8 shown, the locking bolt 3 can slide relative to the base 1 between the first position and the second position of the base 1. When the locking bolt 3 is in the first position, the locking buckle 221 is inserted into the second locking port 32 to achieve locking cooperation. The first plug head 21 slides into the small mouth end 312 of the first locking port 31 to achieve locking cooperation formed at the locking groove 211 and the small mouth end 312. The locking tongue 33 is inserted into the third locking port 231 to achieve locking cooperation, so as to realize the fixed connection between the vacuum device 2 and the base 1. At this time, the vacuum device 2 cannot be removed from the base 1. When it is necessary to move the locking bolt 3 from the first position to the second position, the locking bolt 3 is pulled forward through the handle 35, so that the locking buckle 221 is disengaged from the second locking port 32. The first plug head 21 slides into the large mouth end 311 of the first locking port 31, and the locking tongue 33 is disengaged from the third locking port 231, so as to realize the release of the fixed connection between the vacuum device 2 and the base 1. At this time, the vacuum device 2 can be disassembled from the base 1.

[0048] In this embodiment, the second plug head 22 is provided with two locking latches 221 that cooperate with the second locking port 32. Both of the two locking latches 221 extend forward relative to the second plug head 22. A gap 2211 for the deformation of the locking latch 221 is formed between the two locking latches 221. Raised portions 2212 are provided on the opposite surfaces of the two locking latches 221. The raised portions 2212 are provided with a guiding inclined surface 2213 and a locking inclined surface 2214 that respectively correspond to and cooperate with the second locking port 32. As Figure 6 and Figure 10 shown, the provision of the gap 2211 reserves a deformation space for the deformation of the locking latch 221. When the locking latch 221 is inserted into the second locking port 32, the two locking latches 221 approach each other, so that the raised portion 2212 can enter the second locking port 32. After entering the second locking port 32, the locking latch 221 restores under its own elastic force to achieve the locking function. The provision of the guiding inclined surface 2213 facilitates the locking latch 221 to drive the raised portion 2212 to insert into the second locking port 32. The provision of the locking inclined surface 2214 is used for locking cooperation with the second locking port 32. In a further embodiment, the inclination angle of the locking inclined surface 2214 is larger than the inclination angle of the guiding inclined surface 2213, so that the locking inclined surface 2214 can achieve locking cooperation with the second locking port 32, so as to keep the latch 3 in a state of locking cooperation with the locking latch 221.

[0049] In this embodiment, the first locking port 31 includes a large opening end 311 for the first plug head 21 to enter and a small opening end 312 that is in locking cooperation with the locking groove 211. As Figure 6 、 Figure 8 and Figure 12 shown, when the vacuum device 2 needs to be in locking cooperation with the base 1, the first plug head 21 enters the first locking port 31 through the large opening end 311, and the first plug head 21 slides into the small opening end 312 to achieve locking cooperation between the locking groove 211 and the small opening end 312; when the vacuum device 2 needs to be unlocked from the base 1, the first plug head 21 slides from the small opening end 312 into the large opening end 311 to release the locking cooperation between the locking groove 211 and the small opening end 312, so that the first plug head 21 can be pulled out from the first locking port 31.

[0050] In this embodiment, as Figure 9 and Figure 11 shown, through the plugging cooperation of the first plug head 21, the second plug head 22 and the third plug head 23 with the first socket 11, the second socket 12 and the avoidance opening 222, not only the rapid positioning of the vacuum device 2 is realized, but also a plugging cooperation is formed between the vacuum device 2 and the base 1, rather than a simple end face cooperation. Through the design of this structure, the stability of the connection between the vacuum device 2 and the base 1 is improved.

[0051] As another preferred solution of the present utility model, a first circuit board 232 is provided inside the vacuum device 2, a second circuit board 13 is provided inside the base 1, the third plug head 23 is provided with a pin 2321 or a female socket 131 electrically connected to the first circuit board 232, and the base 1 is provided with a female socket 131 or a pin 2321 electrically connected to the second circuit board 13. When the third plug head 23 is plugged and matched with the second socket 12, the first circuit board 232 and the second circuit board 13 are electrically connected through the plugging and matching of the pin 2321 and the female socket 131. At least part of the first circuit board 232 extends into the interior of the third plug head 23, and the pin 2321 or the female socket 131 provided on the third plug head 23 is integrated on the first circuit board 232. In this embodiment, as Figure 3 and Figure 4 shown, the plugging and matching of the pin 2321 and the female socket 131 is used to replace the traditional wire harness connection. This structural design makes the electrical connection between the vacuum device 2 and the base 1 more convenient. There is no need to straighten out the wire harness from the vacuum device 2 and then connect it to the corresponding end of the base 1. Just insert the pin 2321 into the female socket 131; and this structure makes the connection structure between the vacuum device 2 and the base 1 after installation more compact and the overall appearance more beautiful. In this embodiment, the first circuit board 232 is provided with pins 2321, and the second circuit board 13 is provided with female sockets 131. Of course, as an equivalent replacement, female sockets 131 can also be provided on the first circuit board 232 and pins 2321 can be provided on the second circuit board 13. As long as the pins 2321 and the female sockets 131 are correspondingly arranged to form a plugging and matching, the electrical connection between the first circuit board 232 and the second circuit board 13 can be realized.

[0052] As another preferred solution of the present utility model, a vertical portion 34 arranged at a right angle is provided at the front end of the latch 3, the second locking port 32 is arranged on the vertical portion 34, and the locking buckle 221 is arranged on the front side wall of the second plug head 22. In this embodiment, as Figure 10 and Figure 12 shown, by arranging the locking buckle 221 on the front side wall of the second plug head 22 and arranging the second locking port 32 on the vertical portion 34, the locking mechanism and the unlocking mechanism of the latch 3 and the locking buckle 221 are located at the front end of the vacuum device 2, which is convenient for the user to operate.

[0053] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
