The liquid storage cavity 14 is formed in the housing 26, the insertion hole penetrates from the housing 26 to the liquid storage cavity 14, the adaptor 49 is provided with an insertion column 51 and an adaptor cavity 52 formed inside the adaptor 49, the insertion column 51 is provided with a liquid level hole and the liquid level hole is communicated with the adaptor cavity 52, the upper portion of the adaptor 49 is provided with a butt joint block 58, a butt joint port communicated with the adaptor cavity 52 is formed in the butt joint block 58, the glass tube 50 can be inserted into the adaptor cavity 52 from the butt joint port, the glass tube 50 is provided with an overflow port, when glue liquid exists in the liquid storage cavity 14, the glue liquid can flow to the adaptor cavity 52 from the liquid level hole and enter the glass tube 50 from the overflow port, and therefore the height of the glue liquid is convenient to observe.

The liquid level window structure 48 for the glue spreader comprises a shielding body 53, wherein a mounting hole is formed in the lower part of the shielding body 53, a mounting cavity is formed in the shielding body 53 in a hollow manner, the mounting hole is communicated with the mounting cavity, a glass tube 50 is inserted into the mounting cavity from the mounting hole, and the lower part of the shielding body 53 is connected with a butt-joint block 58; the shielding body 53 can fix the glass tube 50, and the light receiving time of the glue solution in the glass tube 50 can be reduced by the shielding body 53 because the glue solution is easy to cause problems after receiving light for a long time.

However, in order to observe the glue liquid height more conveniently, the shielding body 53 is formed with an observation hole 54, and the observation hole 54 penetrates through the outer surface of the shielding body 53 to the installation cavity; so that the height of the glue can be observed through the observation hole 54.

a blocking position is formed at the upper part of the shielding body 53, and the observation hole 54 extends to the blocking position in a strip shape along the direction from bottom to top; the observation holes 54 are in the shape of bars, and have a wider observation range.

The liquid level window structure 48 for the glue spreader comprises a sleeve 55, wherein a sleeving cavity is formed in the hollow part of the sleeve 55, a sleeving opening is formed at the lower end of the sleeve 55, and the sleeving opening is communicated with the sleeving cavity; the diameter of the shielding body 53 is smaller than that of the sleeving opening; the sleeve 55 can be sleeved on the shielding body 53, so that when the height of the glue solution in the liquid storage cavity 14 needs to be observed, the height of the glue solution can be observed by taking the sleeve 55 up.

In addition, the inner wall of the sleeving cavity is provided with a limiting block 56, and the diameter of the limiting block 56 is smaller than that of the observation hole 54; the stop block 56 is embedded in the observation hole 54; when the sleeve 55 is taken up, the limiting block 56 can limit the sleeve 55 to be taken away, so that the sleeve 55 is prevented from being lost, and the use is very convenient.

A bottom groove 57 is formed at the bottom of the liquid storage cavity 14, the bottom groove 57 extends to the side wall of the liquid storage cavity 14, and an insertion opening penetrates through the side wall of the liquid storage cavity 14 and is arranged opposite to the bottom groove 57; the inserting column 51 is inserted into the inserting opening and embedded into the bottom groove 57; the inserted column 51 is arranged below the bottom of the liquid storage cavity 14, so that the observed actual liquid level of the glue solution can be prevented from being influenced by the horizontal height of the inserted column 51.

A butt joint block 58 is formed at the upper part of the butt joint piece, a butt joint port is formed on the upper surface, away from the adapter piece 49, of the butt joint block 58, the butt joint block 58 is arranged in a vertical direction, and the butt joint block 58 is arranged in a vertical direction; and the inner tube diameter of the glass tube 50 is larger than the maximum diameter of the butt block 58; when the abutment block 58 is fitted into the glass tube 50, the glue does not flow to the lower end of the glass tube 50 but stays on the upper portion of the abutment block 58 because the abutment block 58 is large and small in size.

Wherein, the joint of the inserting column 51 and the shell 26 is provided with a sealing ring 59, the joint of the butt joint block 58 and the glass tube 50 is provided with a sealing ring 59, and the joint of the inserting column 51 and the adaptor 49 is also provided with a sealing ring 59, thereby preventing the glue solution from leaking.

Further, a shielding piece 62 surrounding the housing 26 and a sliding groove 63 formed around the housing 26 are provided on the outer surface of the housing 26, the shielding piece 62 is placed in the sliding groove 63, a through hole having the same diameter as the through hole 46 is provided on the shielding piece 62, and when the shielding piece 62 is rotated and the through hole is arranged to face the through hole 46, the hose can be inserted into the loading hole 45; when not needed for use, the shield plate 62 may be rotated to cover the through-hole 46.

And a handle 60 is also arranged on the control device 12, so that the handle 60 is convenient to use for extracting and gluing the machine.

The lower portion of the shell 26 is connected with a base 61, the shell 26 and the liquid level window structure 48 are fixed on the base 61, the base 61 is made of a heavy metal material, preferably iron, so that the overall gravity center of the glue spreader moves downwards, and the glue spreader is prevented from toppling over in the using process.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
