Referring to fig. 1, a structure of a paste ejection gun 100 according to a preferred embodiment of the invention is shown, in which the paste ejection gun 100 includes a gun body forming a main structure of the paste ejection gun 100. For supplying the handheld operation of user and spraying colloid, the spray gun body of a gun includes:

handle 110

In the lower half of the gun body, there is a handle 110 for the user to hold, and the handle 110 may have a trigger 114 portion for controlling the entry of gas or the opening of the gas when the user presses the trigger 114 portion. That is, the handle 110 is also connected to an external air source to control the intake state of the air source.

Barrel 120

A barrel 120 is secured to the handle 110 and is also connected to the gas source and also receives gas released from the gas source. Meanwhile, the barrel 120 is connected to the glue bottle assembly through a glue spraying tube 126, receives glue from the glue bottle assembly, and sprays the glue from an outlet of the barrel 120.

To achieve the spraying of the glue gun 100 in a small space, the handle 110 may be separated from the barrel 120, and therefore, a separating assembly, which may be a part of the barrel 120 or the handle 110, is provided at the junction of the barrel 120 and the handle 110. Preferably, the separation assembly may specifically comprise: a protrusion fixed to a first end of the handle 110 facing the barrel 120 and extending toward the barrel 120 until reaching the inside thereof, and a fixing portion 121, or in another alternative embodiment, a protrusion fixed to a second end of the barrel 120 facing the handle 110 and extending toward the handle 110 until reaching the inside thereof. Having a boss, the handle 110 and barrel 120 may be interconnected and restrained by the boss. The fixing portion 121 is used for switching between effective and ineffective limiting of the protruding portion, specifically, the fixing portion 121 penetrates from the outside of the gun body (both the handle 110 and the barrel 120) along a direction perpendicular to the protruding portion, after the fixing portion 121 gradually penetrates, the fixing portion 121 collides with the protruding portion, and when the fixing portion collides with the protruding portion, the protruding portion cannot move inside the handle 110 or the barrel 120, so that the relative movement of the handle 110 and the barrel 120 is limited. When the securing portion 121 is released, i.e., removed from the body of the spray gun, the boss is no longer restrained and can move within the handle 110 or barrel 120, thereby freeing the boss from connection with the handle 110 or barrel 120 and the handle 110 and barrel 120 can be unlocked relative to the boss for disengagement. The separated barrel 120 is a small volume component that can be placed in a small space, and the glue can still be input into the barrel 120 for spraying by the user's manipulation of the handle 110.

With reference to fig. 1, in a preferred embodiment, the protruding portion specifically includes a fixing plate 111, a first limiting rib 112 and a second limiting rib 113. The fixing plate 111 is fixedly installed on the first end face or the second end face such that the boss itself is structurally synchronized with the handle 110 or the barrel 120. The first stopper rib 112 is fixed to the fixing plate 111 and extends toward the barrel 120 or the handle 110. The second limiting rib 113 extends from the free end of the first limiting rib 112, and the extending direction of the second limiting rib is the same as or substantially the same as the direction in which the fixing part 121 penetrates into the spray gun body, that is, the first limiting rib 112 and the second limiting rib 113 are erected on the fixing plate 111 in a structure of substantially 90 degrees.

Correspondingly, a groove is formed on the end surface of the barrel 120 or the handle 110 facing the first limiting rib 112 and the second limiting rib 113. The recess can be the L type, when first spacing muscle 112 and second spacing muscle 113 stretched into the recess, laminate with the both sides of L type recess respectively for the notch of recess has restricted second spacing muscle 113 and has shifted out, thereby restriction handle 110 and barrel 120 are at the ascending removal of the extending direction of first spacing muscle 112 and second spacing muscle 113. If first spacing muscle 112 and second spacing muscle 113 need shift out from the recess, at first need with second spacing muscle 113 for recess lateral shifting to the position of recess bottom and facing the notch is removed to second spacing muscle 113, again with first spacing muscle 112 for recess vertical shifting, take out first spacing muscle 112 and second spacing muscle 113 from the recess.

Further, the fixing portion 121 is in a screw shape, or a screw is directly used as the fixing portion 121. Correspondingly, a through hole is formed in the barrel 120 or the handle 110, and two sides of the through hole are connected to the outside of the gun body of the spray gun and the side of the first limiting rib 112, so that the fixing portion 121 gradually penetrates from the outside of the through hole and then can abut against the first limiting rib 112, or when the fixing portion 121 is pulled out, the fixing portion will not abut against the first limiting rib 112. That is, when the fixing portion 121 abuts against the first limiting rib 112, the first limiting rib 112 is limited by the fixing portion 121 along the transverse direction, and the second limiting rib 113 is also limited in the groove, so that the barrel 120 is fixed to the handle 110; when the fixing portion 121 is screwed out of the through hole, a release stroke is formed between the fixing portion 121 and the first limiting rib 112, and the first limiting rib 112 can move along the release stroke, so as to drive the second limiting rib 113 to move to the notch position of the groove, and then the handle 110 and the barrel 120 move along the vertical direction, so that the two can be separated. The user can spray the area to be sprayed by holding the gun tube 120 only.

In a preferred embodiment, the handle 110 specifically includes:

-a first air valve

The first air valve is disposed at the bottom end of the handle 110 and connected to an air source through a first air tube, so that air is sucked through the first air tube.

-a second trachea

One end of the second air tube extends into the handle 110 and is communicated with the first air valve, and the other end extends to the air source.

Trigger part 114

The trigger 114 is similar to the "trigger" of the handle 110 and is connected between the first gas valve and the second gas tube, and when the user applies an external operation to the trigger 114, the first gas valve is triggered to be turned on or off, and gas can enter the handle 110 from the first gas tube. Then the gas flows back to the gas source from the second gas pipe, and the gas is guided to the rubber bottle assembly by the gas source, so that the rubber bottle is extruded under control, and the rubber body flows out.

In a further preferred or alternative embodiment, the barrel 120 includes:

on-off valve 122

A third air tube 125 is disposed inside the barrel 120 and connected to the air source, and the switch valve 122 partially protrudes from the barrel 120, so that a user can hold the protruding portion of the switch valve 122 and push the switch valve 122 left and right, thereby controlling the switch valve 122 to switch between an open state and a closed state, and further controlling the third air tube 125 to be turned on and off.

Flow valve 123

The flow valve 123 is disposed in the barrel 120 and is specifically located on the path of the third gas pipe 125 in the barrel 120, and when the third gas pipe 125 is controlled to be in an open state by the switch valve 122, the flow valve 123 controls the flow rate of the intake gas of the third gas pipe 125.

Injection valve 124

The injection valve 124 is disposed at the head of the barrel 120 and is connected to the third air pipe 125 and the glue injection pipe 126, that is, the injection valve 124 receives the air pressure of the third air pipe 125 and the glue in the glue injection pipe 126 at the same time, and when the glue and the air pressure are converged at the injection valve 124, the air pressure ejects the glue in the glue injection pipe 126 from the injection valve 124. It can be understood that the control of the air pressure through the flow valve 123 realizes the control of the flow rate and the angle of the colloid ejection by the flow valve 123.

More specifically, the flow valve 123 includes a flow control end cap, an inlet end and an outlet end. The flow control cap is exposed to the exterior of the barrel 120 and the user may rotate the flow control cap to control the flow of air pressure. The air inlet end is connected with the third air pipe 125, and the air outlet end is connected to the injection valve 124 through a fourth air pipe (or the third air pipe 125 and the fourth air pipe are the same air pipe, and the middle part is connected by the flow valve 123). When the user operates the outside of the flow control cap, the flow rate of the fourth air tube is further adjusted, thereby controlling the injection speed and the injection angle of the injection valve 124.

In another preferred embodiment, the barrel 120 includes a receiving portion 127 disposed at the top of the barrel 120 and extending through the middle thereof to form a receiving space, so that the glue-spraying tube 126 is placed in the receiving space and the glue-spraying tube 126 is prevented from moving on the barrel 120. In order to facilitate the fine adjustment of the position of the glue spraying pipe 126 accommodated in the accommodating part 127 by a user, the length of the accommodating part 127 is gradually reduced along the direction from the fixed end to the free end, and the top surface of the accommodating part 127 is provided with at least one window unit, so that the user can observe the position of the glue spraying pipe 126 from the window unit on one hand and can stretch into the window unit to adjust the position of the glue spraying pipe 126 on the other hand. And it can be understood that the size of the receiving space can be equal to or slightly larger than the diameter of the glue spraying tube 126, so as to prevent the glue spraying tube 126 from moving freely in the receiving part 127.

Referring to fig. 2, a schematic diagram of a glue bottle assembly 200 according to a preferred embodiment of the invention is shown. In this embodiment, the glue bottle 210 is disposed inside the glue bottle 210 and connected to a glue spraying tube 211 for transferring the glue to a glue spraying gun, and the glue is sprayed out from the glue spraying gun. To separate the glue bottle 210 from the glue gun so that the glue bottle 210 and the glue gun can be remotely located apart so that the volume of the glue bottle 210 does not participate in the working position, the glue bottle assembly 200 includes:

glue bottle housing 220

In order to place the glue bottle 210, a glue bottle housing 220 is additionally provided outside the glue bottle 210. When the area to be sprayed needs to be sprayed, the glue bottle 210 with the glue inside can be fixedly installed in the glue bottle housing 220. When the glue bottle 210 needs to be moved, the glue bottle housing 220 is simply moved to realize the arbitrary movement of the position of the glue bottle 210.

It will be appreciated that the glue bottle 210 may be removed from the glue bottle housing 220 when spraying of the work area is not required. Therefore, in order to realize the detachably installation of the glue bottle 210, a mounting groove is provided in the middle of the glue bottle housing 220, the glue bottle 210 can be embedded into the mounting groove, and the glue can be ejected out by the pushing of the air pressure push rod in the mounting groove.

Glue bottle holder 230

In order to further fix the rubber bottle housing 220, a rubber bottle support 230 is further provided outside the rubber bottle housing 220, so that the rubber bottle housing 220 can be fixedly mounted on the rubber bottle support 230. When the plastic bottle casing 220 is located on the plastic bottle support 230, the plastic bottle support 230 supports the plastic bottle casing 220, so that the plastic bottle casing 220 cannot be randomly placed on the ground in a working environment. Therefore, the glue bottle holder 230 includes a support plate 231 and a control chamber 232. The supporting plate 231 is disposed facing the rubber bottle housing 220 to form a supporting end face for supporting the rubber bottle housing 220, so that the rubber bottle housing 220 is placed on the supporting surface. The control chamber 232 is fixed at the side of the rubber bottle housing 220 and is communicated with the rubber bottle housing 220 through an air tube and other elements. The control chamber 232 is further externally connected with an air source and a glue-squeezing spray gun, and the glue-squeezing spray gun can be connected through an air pipe, is far away from the control chamber 232, but is still in the same working scene with the control chamber 232. The air source inputs air into the control chamber 232, and the air is distributed by the control chamber 232, for example, into the glue bottle housing 220, to squeeze the glue bottle 210, or to the glue gun, so that the glue gun can spray the sucked glue by using the air. That is, gas is distributed within the control chamber 232 and exchanged within the glue gun, glue bottle housing 220.

With the above configuration, when the user uses the glue squeezing spray gun, the user can only hold the glue squeezing spray gun to the working surface, the glue bottle assembly 200 can be placed outside, and then in order to separate the glue bottle assembly 200 from the glue squeezing spray gun, the glue bottle support 230 and the glue bottle housing 220 can support the glue bottle 210, and limit the same.

In a preferred embodiment, the glue bottle holder 230 further comprises a portable handle 233 fixedly mounted to the support plate 231, for example, by a U-shaped spring and a screw to fix the portable handle to the support plate 231. The portable handle 233 also extends away from the control chamber 232 such that an insertion space is formed between the portable handle 233 and the support plate 231. When a user needs to move or transport the glue bottle assembly 200, the user can put his or her hand into the space and hold the portable handle 233 to transport the portable handle 233 and the glue bottle assembly 200 together.

In another preferred embodiment, the glue bottle holder 230 further includes a universal wheel 234 fixed below the supporting plate 231, for example, 4 or even number of universal wheels can be placed below the supporting plate 231, and when the user needs to move the glue bottle assembly 200 in the working scene, the user can hold the portable handle 233 or the air tube between the glue gun and the control chamber 232 to pull the glue bottle assembly 200. By using the universal wheel 234, the force required for pulling can be reduced, and the user can move the glue bottle assembly 200 conveniently.

In another preferred or optional embodiment, the glue bottle holder 230 further comprises an extension plate, one end of the extension plate is fixed to the side of the support plate 231 on which the glue spraying tube 211 is disposed, so that the extension plate is right opposite to the glue spraying tube 211, and the other end of the extension plate extends in a direction away from the glue bottle housing 220. Because the glue spraying tube 211 has a certain length, and is different from the design of the prior art that the glue spraying tube 211 directly faces the working surface, the length required by the glue spraying tube 211 in the embodiment needs to be extended to the glue extruding spray gun, and therefore, the glue spraying tube 211 does not have a downward trend. Furthermore, the free end of the extension plate is provided with a notch, the glue spraying pipe 211 is placed in the notch, and the extension plate supports the glue spraying pipe 211 to ensure that glue does not flow back.

Further, to better fix the extension plate, the glue bottle holder 230 further includes a side plate 235 vertically fixed on the side of the support plate 231 on which the glue spraying tube 211 is disposed, so as to limit the position of the glue bottle housing 220 on the support plate 231 and further limit the position of the glue bottle 210 in the glue bottle housing 220. Correspondingly, the extension plate is fixed on the side plate 235 and is flush with the glue spraying pipe 211, so that the extension plate does not need to be arranged on the glue bottle shell 220 to maintain the strength of the glue bottle shell 220.

Preferably or optionally, the glue bottle assembly 200 further comprises: a first positioning element 236, fixedly mounted on the supporting plate 231 at a position corresponding to the rubber bottle 210, and supporting the rubber bottle housing 220; a second positioning element 237, which is fixedly mounted on the supporting plate 231 at a position corresponding to the rubber bottle housing 220 and supports the rubber bottle housing 220; the fixing ring 238 is disposed around the glue bottle housing 220 and fixed to the second positioning element 237, such that the fixing ring 238 has no gap in the glue bottle housing 220. In this embodiment, the first positioning element 236 is adapted to the shape of the bottom or end of the glue bottle 210, and the whole body may be L-shaped, while the second positioning element 237 is adapted to the shape of the bottom of the glue bottle housing 220, and the end surface of the second element facing the glue bottle housing 220 may be curved or curved. After the fixing ring 238 is disposed around the outside of the glue bottle housing 220, the fixing ring 238 and the second positioning element 237 can be fixed by screws or the like, so that the glue bottle housing 220 and the glue bottle 210 will not shake on the glue bottle assembly 200.

Preferably or optionally, the control chamber 232 comprises a first control switch 221 connected to the first air pipe and the second air pipe between the air source and the glue-extruding spray gun; the second control switch 222 is connected to the third air pipe between the air source and the glue-squeezing spray gun and the fourth air pipe between the air source and the glue bottle 210. The first control switch 221 and the second control switch 222 are partially protruded out of the control cavity 232, so that a user can control the first control switch 221 and the second control switch 222, when the first control switch 221 receives a pressing operation, the first air pipe and the second air pipe can be controlled to be simultaneously switched on and off, namely, whether the air of the air source is conveyed to the glue-extruding spray gun or not, and the glue received by the glue-extruding spray gun is sprayed out or is suspended. And when second control switch 222 received the press operation, will control the alternative of third trachea and fourth trachea and open and turn-off for when glue-spraying pipe 211 connects at the third trachea, can extrude gluey bottle 210, when glue-spraying pipe 211 connects at the fourth trachea, when will glue-spraying pipe 211 again connects at the fourth trachea, usable gas will spout the surplus colloid blowout in glue-spraying pipe 211, prevent that the colloid from condensing in glue-spraying pipe 211.

Furthermore, an air valve 223 and an air inlet pipe are connected to the side of the control cavity 232; the air inlet pipe is connected with an air source, and the air valve 223 controls the flow rate of air in the air inlet pipe, so that the spraying speed of the externally connected glue extruding spray gun is controlled.
