[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Reference Figures 1-7 The material cylinder 100 of this utility model is detachably installed on the upper part of the support body 200. For example... Figure 1 As shown, the material cylinder 100 includes an outer surface 101 located at the bottom. In one embodiment, the outer surface 101 is a curved surface. In other embodiments, the outer surface 101 may also be an inclined surface relative to a horizontal plane, or a combination of partially inclined surfaces and partially curved surfaces. A connector 300 is provided on the outer surface 101. In one embodiment, the first end of the material cylinder 100 has a discharge nozzle 102, and the connector 300 is symmetrically arranged on both sides of the discharge nozzle 102. In one embodiment, the connector 300 is located at the bottom of the material cylinder 100 and close to the first end of the material cylinder 100.

[0032] The upper part of the support body 200 has a material cylinder connection position 210, which is detachably connected to the connector 300. In one embodiment, such as Figures 2-4A As shown, the material cylinder connection position 210 has a downward recess 215, and the connector 300 has a downward protrusion 330 that cooperates with the recess 215. When the connector 300 moves with the material cylinder 100 to above the recess 215, under the action of gravity, the protrusion 330 falls into the recess 215, which can stably connect the material cylinder 100 to the upper part of the support body 200. Furthermore, the protrusion 330 is restricted by the recess 215 from moving back and forth in the horizontal direction (i.e., along the direction of the material cylinder 100's entry and exit), so that the connection mechanism can simultaneously lock the horizontal position of the material cylinder 100, and, relying on the weight of the material cylinder 100 itself (especially after the material is injected, the weight continues to increase), the connection mechanism can also fix the material cylinder 100 in the vertical direction.

[0033] In one embodiment, the cylinder connecting position 210 has a guiding support surface 211 extending substantially along the entering direction of the cylinder 100 when mounted to the support body 200, and the connecting member 300 has a support part 320 in contact with the guiding support surface 211, and the side of the support part 320 facing the cylinder connecting position 210 has a contact surface 322, in one embodiment, the contact surface 322 forms a surface contact with the guiding support surface 211, so that after the mounting, the protrusion 330 is clamped into the recess 215, and the contact surface 322 forms a surface contact with the guiding support surface 211, which increases the friction between the bottom of the cylinder 100 and the support body 200, and makes the connection between the two more stable. Further, as shown in Figure 4 and Figure 4A In one embodiment, the guiding support surface 211 forms an acute angle α with the horizontal plane, and the end close to the recess 215 is a lower point, and the end away from the recess 215 is a higher point, and the line connecting the lower point and the higher point forms the above-mentioned angle with the horizontal plane, so as to ensure that when subjected to a slight outward pulling force or pushing force, the cylinder 100 can still rely on the certain horizontal direction friction and pressure between the guiding support surface 211 and the contact surface 322, and will not be pulled out or pushed out. In one embodiment, other structures for increasing friction can also be provided between the guiding support surface 211 and the contact surface 322, such as increasing the roughness of the corresponding surfaces, providing a blocking mechanism, etc., which can be thought of by those skilled in the art, and will not be described in detail.

[0034] In one embodiment, the number of connecting mechanisms composed of the recess 215 and the protrusion 330 is a multiple of 2. In one embodiment, two or more adjacent connecting structures on the same side are arranged substantially along the entering direction of the cylinder 100 into the support body 200.

[0035] In one embodiment, as shown in Figures 3-7 part of the protrusion 330 extends downward from the support part 320, and another part of the protrusion 330 extends outward from the outer side surface 101, the meaning of extending outward is extending from the cylinder 100 to the support body 200, including extending in the radial direction on the horizontal plane, and also including extending in other directions, in short, the protrusion 330 aims to enter the recess 215. In this embodiment, the support part 320 can also act as a pressure transmission mechanism for the protrusion 330, which transmits and disperses the upward pressure received by the protrusion 330 to the entire connecting member 300 and the cylinder 100, so that the protrusion 330 does not need to bear excessive pressure and is easy to damage. In another embodiment, the protrusion 330 is not connected to the support part 320.

[0036] The protrusion 330 extends radially towards the recess 215 in the horizontal plane, so that it has a certain length in the radial direction. The extension of the protrusion 330 in the radial direction provides certain reinforcing support to the body of the cylinder 100, and makes the connection between the protrusion 330 and the outer side 101 more stable.

[0037] To more easily guide the cylinder 100 into the upper portion of the support body 200, the inner wall of the support body 200 is substantially matched in shape to the outer side 101 of the cylinder 100. The inner wall of the support body 200 includes an upper inner wall 216 and a bottom inner wall 217. In one embodiment, the cross section of the outer side 101 of the cylinder 100 below the middle portion is substantially semicircular or semioval, and the cross section of the upper inner wall 216 is also substantially partially circular or partially oval, and the diameter of the cross section of the upper inner wall 216 is slightly larger than the diameter of the cross section of the outer side 101. In other embodiments, the cross sections can also be partially polygonal or other shapes, depending on the shape of the bottom portion of the cylinder 100.

[0038] In one embodiment, when the cylinder 100 is installed, as shown in Figure 3 , there is a gap 500 between the upper inner wall 216 and the outer side 101. The connecting member 300 has a guide portion 310 protruding outward from the outer side 101, and the guide portion 310 is located in the gap 500. As shown in Figure 3A , during installation, as the cylinder 100 is gradually pushed into the support body 200, the width W1 of the guide portion 310 in the horizontal plane gradually increases in the direction of entry of the cylinder 100, until the width W1 is less than or equal to the width W2 of the gap 500, which is generally considered to be equal everywhere.

[0039] In one embodiment, the guide portion 310 has an arc-shaped guide surface 311 and a guide flat surface 312. During installation, the arc-shaped guide surface 311 enters the upper portion of the support body 200 first, and the guide flat surface 312 enters subsequently. In the horizontal plane, the front end of the arc-shaped guide surface 311 is very close to or even touches the outer side 101, and the distance between the rear end of the arc-shaped guide surface 311 and the outer side 101 gradually increases and approaches the distance between the guide flat surface 312 and the outer side 101. In addition, during entry of the cylinder 100, the arc-shaped surface of the arc-shaped guide surface 311 can minimize the contact area between the outer side 101 and the upper inner wall 216, thereby reducing resistance during entry and optimizing the user experience. When the cylinder 100 just enters the upper portion of the support body 200, the arc-shaped guide surface 311 can allow for a certain amount of operating error by the user, as long as the other end of the cylinder 100 can be placed. As the cylinder 100 is pushed forward, the guide portion 310 gradually corrects the operating error by means of the arc-shaped guide surface 311 and the guide flat surface 312, until the cylinder 100 is guided to the correct entry direction. In one embodiment, the guide flat surface 312 can also be a curved surface.

[0040] As the protrusion 330 needs to be temporarily kept above the recess 215 during the process of placing the material cylinder 100 on the upper part of the support body 200, the material cylinder 100 is in an inclined state during the process, as shown in Figure 5 and Figure 5A Correspondingly, when the material cylinder 100 needs to be detached from the upper part of the support body 200, the material cylinder 100 also needs to be lifted up at the end close to the material outlet faucet 102 until the protrusion 330 is out of the recess 215. In a preferred embodiment, the material cylinder connecting position 210 has a first guide slope 212 which is inclined at an appropriate acute angle β upward from the bottom of the material cylinder connecting position 210 and toward the entering direction of the material cylinder 100, and the minimum angle of the acute angle β is not less than the minimum angle of the acute angle a, so as to ensure that the connecting member 300 does not unnecessarily contact the inner wall of the material cylinder connecting position 210 when the material cylinder 100 is in the inclined state during the above two processes, thereby reducing the resistance of installation and detachment. The first guide slope 212 can be a plane or a curved surface, as long as it can achieve the effect of avoiding the connecting member 300, especially the guide part 310 and the protrusion 330.

[0041] In the above two processes of installation and detachment, in order to avoid the collision or friction between the material cylinder 100 and the upper inner wall 216 and the bottom inner wall 217 of the support body 200 as much as possible due to the operation errors of the user, the position of the upper inner wall 216 and the bottom inner wall 217 above the recess 215 forms a second guide slope 213, as shown in Figure 3A and Figure 6 The second guide slope 213 extends upward from the bottom of the material cylinder connecting position 210 and is inclined outward at an appropriate angle, which to some extent expands the space above the upper part of the support body 200, especially above the material cylinder connecting position 210, and further guides the connecting member 300 to descend to a position closer to the recess 215. At this time, the arc-shaped guide surface 311 and the guide plane 312 can also reduce the contact (forming line contact or smaller area of surface contact) between them during the descending process along the second guide slope 213, thereby ensuring that the material cylinder 100 avoids the collision or friction with the inner wall (i.e. the upper inner wall 216 and the bottom inner wall 217) of the support body 200 as much as possible during the above two processes. Similarly, the second guide slope 213 can be a plane or a curved surface, as long as it can achieve the above technical effects.

[0042] The first end of the hopper 100 with the discharge tap 102 occupies a large portion of the weight of the hopper 100, so the geometric center of gravity of the hopper 100 is close to the first end. After the user pushes the second end of the hopper 100 into the correct position, the first end of the hopper 100 is only released by the user, and the first end of the hopper 100 naturally falls into the correct position due to the joint action of the guide mechanisms, and the protrusion 330 enters the recess 215. When the hopper 100 enters the correct position, the user will also give clear tactile and auditory feedback, and the user can confirm that the hopper 100 is installed without observation. When disassembling the hopper 100, the user only needs to lift the first end of the hopper 100 and pull the hopper 100 outward to disassemble it.

[0043] At the end of the hopper connecting position 210 of the support body 200 away from the discharge tap 102 (i.e. the second end of the hopper 100), there is a hopper positioning part. In the embodiment shown in Figure 6 In the embodiment shown, the hopper positioning part is an arc-shaped groove 220, and when the second end edge of the hopper 100 touches the arc-shaped side wall 221 of the arc-shaped groove 220, the second end of the hopper 100 enters the correct position.
