[0074] The side spray type one-way spray valve of the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0075] Refer to Figures 1 to 8 As shown, the side spray type one-way spray valve provided by the embodiments of the present utility model includes a connection base 10, a glue feeding assembly 20, a needle assembly 30, a valve assembly 40 and a gas supply assembly.

[0076] The connection base 10 is assembled on the driving mechanism of the dispensing device and can move along the side wall of the intelligent device product under the drive of the driving mechanism.

[0077] The glue feeding assembly 20 is communicated with the connection base 10 and is used for providing glue. The glue feeding assembly 20 may be a glue bucket with glue stored inside, and the glue can be automatically discharged into the connection base 10 for dispensing use.

[0078] The needle assembly 30 is connected to the connection base 10. An adhesive outlet channel 321 is vertically arranged inside the needle assembly 30. The adhesive outlet channel 321 is communicated with the glue feeding assembly 20, and an adhesive outlet pipe 341 is horizontally arranged at the lower end of the needle assembly 30. The adhesive outlet pipe 341 is communicated with the adhesive outlet channel 321.

[0079] The needle assembly 30 is disposed at the bottom of the connection base 10. An adhesive outlet passage 321 is provided therein. The adhesive outlet passage 321 is vertically arranged and communicates with the connection base 10. An adhesive outlet tube 341 is provided at the bottom of the adhesive outlet passage 321. The adhesive outlet tube 341 is horizontally arranged. Therefore, the glue discharged by the glue inlet assembly 20 enters the adhesive outlet passage 321 and then can be horizontally discharged from the horizontally arranged adhesive outlet tube 341. In this way, it can just be sprayed onto the side wall of the product opposite to the adhesive outlet tube 341, thus successfully completing the dispensing.

[0080] The valve assembly 40 includes a drive base 42, a valve core 43 and a drive member 41; the drive base 42 is disposed in the connection base 10 and is connected to the valve core 43; the drive member 41 is connected to the connection base 10 and is used to drive the drive base 42 to move in the vertical direction, so as to drive the valve core 43 to move in the vertical direction in the adhesive outlet passage 321 to open or close the adhesive outlet passage 321.

[0081] The valve assembly 40 serves as a switch for the adhesive outlet passage 321 and can open the adhesive outlet passage 321 during dispensing and close the adhesive outlet passage 321 when not dispensing. Specifically, it includes a drive base 42, a valve core 43 and a drive member 41. The drive base 42 is connected to the drive member 41 and the valve core 43. Driven by the drive member 41, the drive base 42 can move accordingly, and then drive the valve core 43 to move up and down, thereby realizing the opening or closing of the adhesive outlet passage 321.

[0082] The air supply assembly is used to supply air to the end of the adhesive outlet tube 341 to atomize the glue ejected from the adhesive outlet tube 341.

[0083] The air supply assembly can introduce gas into the needle assembly 30 and make the gas eject from around the adhesive outlet tube 341. In this way, the gas can be atomized, so that the other can uniformly contact the side wall of the product, thereby improving the bonding effect of the glue.

[0084] More specifically, when dispensing glue on the side wall of a product, first, use the driving mechanism on the dispensing device to drive the needle assembly 30 in the present application to move inside the product, so that the glue outlet tube 341 on the needle assembly 30 faces the side wall of the product. In this way, the glue discharged from the glue outlet tube 341 can just contact the side wall of the product. Then, cooperate the driving member 41 and the driving seat 42 of the valve assembly 40 to make the valve core 43 move upward to open the glue outlet channel 321. Further, discharge the glue in the glue feeding assembly 20 into the glue outlet channel 321 and discharge it horizontally from the glue outlet tube 341. At the same time, introduce gas into the seat body 11 through the air supply group, so that the gas is discharged from around the glue, so that the gas can be atomized and evenly contact the product. At the same time, it can also prevent the glue from splashing around and affecting the dispensing effect, thus completing the dispensing process. After the dispensing is completed, cooperate the driving member 41 and the driving seat 42 again to make the valve core 43 move downward to close the glue outlet channel 321 for subsequent dispensing.

[0085] According to the side spray type one-way spray valve provided by the present invention, on the one hand, the glue can be sprayed horizontally, which is beneficial to dispensing the side wall of the product. On the other hand, the glue can be atomized, and then the glue can be evenly sprayed on the product.

[0086] Advantageously, in an embodiment of the present invention, the connecting seat 10 includes a seat body 11 and a connecting rod 12;

[0087] A first through hole 111 is arranged inside the seat body 11, and the first through hole 111 extends in the vertical direction, and the needle assembly 30 is penetrated through the first through hole 111;

[0088] The connecting rod 12 is arranged on one side of the seat body 11, and a second through hole 121 is arranged inside the connecting rod 12. The second through hole 121 extends in the horizontal direction, and the second through hole 121 is communicated with the glue outlet channel 321; the glue feeding assembly 20 is arranged on the connecting rod 12 and communicated with the second through hole 121.

[0089] The connecting rod 12 is horizontally arranged on one side of the seat body 11. The first through hole 111 on the seat body 11 is vertically opposite to the glue outlet channel 321 on the needle assembly 30 and communicated with each other. The valve core 43 of the valve assembly 40 penetrates from the second channel into the glue outlet channel 321. At the same time, the left end of the second through hole 121 in the connecting rod 12 is communicated with the middle part of the first through hole 111, and the right end is connected with the glue feeding assembly 20 arranged on the connecting rod 12. In this way, the glue provided by the glue feeding assembly 20 can enter the first through hole 111 along the second through hole 121, flow into the glue outlet channel 321 from the first through hole 111, and finally be sprayed onto the product from the glue outlet tube 341, thus completing the dispensing of the product.

[0090] Advantageously, in an embodiment of the present utility model, the needle assembly 30 includes a needle tube 32, a needle tube sleeve 31, a sealing member 33, and an end cap 34;

[0091] The upper end of the needle tube sleeve 31 is inserted into the first through hole 111;

[0092] The needle tube 32 is inserted into the needle tube sleeve 31, and the glue outlet channel 321 is arranged in the needle tube 32 and communicated with the second through hole 121;

[0093] The sealing member 33 is arranged in the needle tube sleeve 31 and located at the lower end of the glue outlet channel 321. The valve core 43 passes through the first through hole 111 and the glue outlet channel 321 into the sealing member 33, and can be driven by the driving seat 42 to open or close the sealing member 33;

[0094] The end cap 34 is arranged at the lower end of the needle tube sleeve for installing the sealing member 33 in the needle tube sleeve 31, and the glue outlet tube 341 is arranged in the end cap 34.

[0095] That is to say, the needle tube sleeve 31 is used to connect the needle tube 32 to the bottom of the seat body 11, so that the glue outlet channel 321 in the needle tube 32 is vertically opposite to and communicated with the first through hole 111 on the seat body 11. A sealing member 33 is arranged at the lower end of the needle tube sleeve 31, and the sealing member 33 is located at the lower end of the glue outlet channel 321 and is communicated with each other. In this way, the valve core 43 passing through the first through hole 111 can move into the lower sealing member 33 under the drive of the driving seat 42 and the driving member 41 to seal the glue outlet channel 321, or can move out of the sealing member 33 under the drive of the driving seat 42 and the driving member 41 to open the sealing member 33. The end cap 34 arranged at the lower end of the needle tube sleeve, on the one hand, can abut against the sealing member 33 to clamp and fix the sealing member 33 in the needle tube sleeve 31, and on the other hand, the glue outlet tube 341 arranged therein is communicated with the sealing member 33, so that the glue is discharged horizontally to facilitate dispensing on the side wall of the product.

[0096] Advantageously, in another embodiment of the present utility model, a glue passing hole 331 is arranged on the sealing member 33, the glue passing hole 331 is communicated with the glue outlet tube 341, and the inner diameter of the glue passing hole 331 gradually decreases from top to bottom;

[0097] The lower end of the valve core 43 is a pointed structure. When the driving seat 42 drives the valve core 43 to move downward, the lower end of the valve core 43 abuts against the glue hole 331 to close the glue hole 331; when the driving seat 42 drives the valve core 43 to move upward, the lower end of the valve core 43 and the glue hole 331 are staggered to open the glue hole 331.

[0098] That is, the glue hole 331 on the closing member 33 is a structure adapted to the lower end of the valve core 43, and driven by the driving seat 42, the lower end outer wall of the valve core 43 can be abutted against the side wall of the glue hole 331, thereby blocking the glue hole 331. In this way, the glue hole 331 can be closed, and accordingly, the glue outlet channel 321 can also be closed; conversely, driven by the driving seat 42, the lower end outer wall of the valve core 43 can be displaced and separated from the side wall of the glue hole 331, thereby opening the glue hole 331, and accordingly, the glue outlet channel 321 can also be opened, so as to facilitate smooth dispensing.

[0099] Advantageously, in some embodiments of the present invention, an air outlet channel 342 is provided in the end cover 34 at the periphery of the rubber outlet pipe 341 , and the air outlet channel 342 extends to the seat body 11 and is communicated with an air supply assembly provided on the seat body 11 .

[0100] The air outlet channel 342 is arranged around the glue outlet pipe 341 and is connected with the air inlet hole on the base body 11. An air inlet is arranged on the base body 11, and the air supply component is connected with the air inlet. The air supply component can fill the gas into the air inlet hole through the air inlet, and then the gas is discharged from the air outlet channel 342, and the glue sprayed out of the glue outlet pipe 341 is atomized, so that the atomized glue can be evenly sprayed on the side wall of the smart device product, thereby completing the dispensing of the side wall of the product.

[0101] Advantageously, in some embodiments of the utility model, a cavity 112 is provided inside the seat body 11, and the driving seat 42 is provided in the cavity 112 and connected to the upper end of the valve core 43, and is used for driving the valve core 43 to move up and down under the drive of the driving member 41 to open or close the glue hole 331.

[0102] Furthermore, the driving member 41 includes an inflatable member 411 and an elastic member 412;

[0103] The inflatable member 411 is in communication with the cavity 112 and is used to inflate the cavity 112 so as to drive the driving seat 42 to drive the valve core 43 to move upward to open the glue hole 331;

[0104] The elastic member 412 is disposed in the cavity 112, with its lower end connected to the driving seat 42 and its upper end connected to the connecting seat 10 provided on the seat body 11, and is used to drive the valve core 43 to move downward to close the glue passing hole 331.

[0105] Specifically, the driving seat 42 is movably disposed in the cavity 112 and divides the cavity 112 into two sealed upper and lower spaces. The inflating member 411 is connected to the lower sealed space, and thus can inflate the interior of the lower sealed space, so that the air pressure in the lower part of the driving seat 42 is greater than the air pressure in the upper sealed space. Therefore, the driving seat 42 can be pushed to move upward in the cavity 112 by the air pressure difference. As the driving seat 42 moves upward, the valve core 43 connected to the driving seat 42 also moves upward accordingly, and thus is misaligned with the glue passing hole 331. Therefore, the glue outlet channel 321 and the glue passing hole 331 are opened, and the colloid in the glue feeding assembly 20 can be injected therein for dispensing. After the dispensing is completed, since part of the gas in the lower space of the driving seat 42 is discharged from the glue outlet channel 321, and an elastic member 412 is provided in the cavity 112 and the elastic member 412 is connected to the driving seat 42, the elastic force of the elastic member 412 can force the driving seat 42 to move downward in the cavity, and then drive the valve core 43 to move downward, so that the valve core 43 abuts against the glue passing hole 331, thereby sealing the glue passing hole 331, facilitating subsequent opening of the glue outlet channel 321 for dispensing by inflating again.

[0106] Advantageously, in some other embodiments of the present invention, a glue amount adjusting assembly 50 is provided in the connecting seat 10, and the glue amount adjusting assembly 50 is used to adjust the glue output amount of the glue outlet pipe 341.

[0107] Preferably, the glue amount adjusting assembly 50 includes an adjusting member 52 and an adjusting rod 51;

[0108] The adjusting rod 51 is disposed in the cavity 112 and is vertically opposite to the valve core 43;

[0109] The adjusting member 52 is movably connected to the connecting seat 10 and is connected to the upper end of the adjusting rod 51 and the elastic member 412, and is used to adjust the distance between the adjusting rod 51 and the valve core 43.

[0110] That is to say, the position of the adjusting rod 51 in the cavity 112 can be adjusted by the adjusting member 52, thereby adjusting the distance between the adjusting rod 51 and the valve core 43. The adjusting member 52 can be threadedly connected to the connecting seat 10. In this way, by rotating the adjusting member 52, the adjusting rod 51 can be driven to move up and down. Then, through this adjustment, on the one hand, the upward height of the valve core 43 can be restricted, and further the size of the gap between the lower end of the valve core 43 and the glue-passing hole 331 can be restricted. Specifically, when the distance between the adjusting rod 51 and the valve core 43 is larger, under the drive of the driving member 41, the upward distance of the valve core 43 is also larger. Then, when the valve core 43 opens the glue outlet channel 321, the gap between the lower end of the valve core 43 and the glue-passing hole 331 is also larger, and correspondingly, the glue output is also larger; on the contrary, when the distance between the adjusting rod 51 and the valve core 43 is smaller, under the drive of the driving member 41, the upward distance of the valve core 43 is also smaller. Then, when the valve core 43 opens the glue outlet channel 321, the gap between the lower end of the valve core 43 and the glue-passing hole 331 is also smaller, and correspondingly, the glue output is also smaller. On the other hand, by adjusting the adjusting member 52 downward, the elastic member 412 can be driven to move downward. In this way, after the lower end of the valve core 43 and the glue-passing hole 331 are worn, since the elastic member 412 moves downward under the drive of the adjusting member 52, therefore, the elastic member 412 is closer to the valve core 43, and further a larger thrust can be generated to make the valve core 43 move further downward to abut against the glue-passing hole 331 to close the glue-passing hole 331.
