[0002] A coffee machine is an electrical device used for making coffee, which is generally divided into semi-automatic and fully automatic. A semi-automatic coffee machine requires manual operation of grinding, pressing, loading, brewing, and manual removal of residues. A fully automatic coffee machine is a coffee machine that integrates the entire process of brewing coffee, including preheating, cleaning, grinding, pressing, brewing, and draining, and automatically controls the entire process. It brews coffee according to scientific data and procedures, and you can get coffee with just a light press. Both of the above coffee machines require a water tank structure, which is generally located at the rear of the machine body; such as the application number 202322561961.7 disclosed in the Chinese patent document, the authorization announcement date 2024.05.07, and the utility model name "a coffee machine water tank"; another example is the application number 202322123913.X disclosed in the Chinese patent document, the authorization announcement date 2024.03.15, and the utility model name "a coffee machine handle water tank assembly". The above-mentioned structure and similar products generally adopt a handle that is integrated with the barrel mouth component, or the box cover is used as a handle; however, water tanks of this type of structure often have some inconveniences in extraction and operation. On the one hand, the connection between the water tank and the handle is not stable enough, and it may loosen or even fall off during the extraction process, affecting the safety and convenience of use; on the other hand, the existing extraction device design is not user-friendly, and it is more laborious to operate and cannot meet the user's demand for convenience; and there is a lack of filter element structure design, and the stability is poor after installation, which is prone to shaking. Summary of the invention

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a water tank with a handle for a coffee machine in the art, so as to solve the technical problems of the existing similar products, such as poor structural design, inconvenient extraction and installation, poor stability, inconvenient production and use, and poor liquid level detection accuracy. The purpose is achieved through the following technical solutions.

[0004] A coffee machine with a handle water tank, the water tank having a box cover at the top box opening of the water tank, a handle bracket is fixedly provided with a buckle in the middle of the inner diameter of the box opening at the top box opening below the box cover, the handle bracket is connected to the box body as a whole, and a one-way valve is provided at the water outlet at the bottom of the box body; the box body and the box cover are correspondingly rectangular parallelepiped, a rectangular inner hole is provided in the middle of the handle bracket, the handle bracket is a rectangular frame, and a handle is provided at the inner diameter of the rectangular inner hole of the handle bracket; the key points of its structural design are that the middle of the handle is U-shaped and arched, and connecting plates with protrusions and higher than the cover opening are symmetrically provided on both sides of the inner diameter of one side edge of the box cover, and the two ends of the handle are respectively hinged and fixed to the axial holes at the two ends of the rectangular inner hole in the middle of the handle bracket. At the same time, the cylinder of the connecting plate at the box cover is inserted into the column holes at the end corners of the handle bracket at both sides of the notch through two notches symmetrically provided on one side of the box opening at the top of the box body. Therefore, after the box cover, the handle and the handle bracket are assembled as one, they can be installed into the box body through the handle bracket, and the production and assembly are relatively convenient; at the same time, the handle and the handle bracket can be used as a universal part after being assembled in advance, and different box covers can be assembled according to needs.

[0005] A raised handle limiting rib is provided at the top of the middle arch of the handle, and a raised bracket limiting rib is symmetrically provided at the inner diameter of the rectangular inner hole of the handle bracket corresponding to the handle limiting rib; when the handle is rotated and retracted into the rectangular inner hole of the handle bracket, the handle limiting rib of the handle and the bracket limiting rib of the handle bracket are restrained, and the top of the handle is flush with the rectangular inner hole of the handle bracket. Thus, the handle can be easily rotated 180° in the handle bracket, and the user can grab it in different directions; further, when the handle is not in use, it will not fall into the water below.

[0006] One side of the box cover is hinged to one side of the handle bracket of the box opening at the top of the box body through a connecting plate, and the opening and closing angle is 100 degrees up and down.

[0007] The hinged parts at both ends of the handle and the handle bracket are arranged parallel or perpendicular to the hinged parts at both ends of the box cover. In the above structure, since the box body and the box cover are rectangular parallelepiped, it is better to arrange the handle parallel to the opening direction of the box cover.

[0008] The one-way valve is arranged at the middle water outlet at the bottom of the box body below the handle bracket, and a raised and equidistant ring-shaped filter column is provided on the outside of the middle water outlet at the bottom of the box body above the one-way valve. The outer diameter of one end of the water filter base is snap-fastened to the filter column of the box body, and the seat opening at the other end of the water filter base is snap-fastened to the cover opening at one end of the cover body of the water filter top cover, and a filter element is provided in the water filter base.

[0009] The top of the other end of the cover of the water filter top cover is provided with a push rod, and the end of the push rod is provided with a terminal head larger than the diameter of the push rod. The cover, push rod and terminal head of the water filter top cover are integrally injection-molded, and the terminal head of the water filter top cover is located in the middle of the rectangular inner hole of the handle bracket in the box body. The inner peripheral surface of the cover of the filter top cover is provided with a protrusion and a grid rib that interferes with fixing the filter element. This makes it easy to take out the filter element through the terminal head of the filter top cover and replace the filter element and put it back after fixing it in the filter top cover, without removing the water in the box body before replacing the filter element.

[0010] The bottom of the box body is provided with a bottom groove opening toward the installation side, and the bottom boss at the one-way valve in the middle of the bottom groove is provided with a middle column sleeve protruding downward, and the height of the middle column sleeve is lower than the peripheral edges of the three sides of the bottom groove. A mounting groove that is integrally connected with the bottom groove is provided below the mounting position of the handle bracket in the middle of the groove surface on the installation side of the body of the box body, and the width of the bottom boss where the bottom boss of the box body is integrally connected with the mounting groove is smaller than the width of the mounting groove. An arc-shaped edge protruding longitudinally from the top to the bottom is provided in the middle of the installation groove of the box body, and the protruding height of the arc-shaped edge is less than the depth of the installation groove. Thus, while the middle column sleeve at the bottom of the box body is inserted into the water inlet at the rear of the body, the bottom groove, groove surface, installation groove and bottom boss of the box body are respectively installed in correspondence with the protrusion and groove on the installation side of the body to prevent the water tank from shaking.

[0011] The two sides of the opening end of the bottom groove of the box body are respectively provided with introduction ribs, and the inner walls on both sides of the bottom groove are symmetrically provided with positioning ribs, so as to further improve the grooves and positioning cooperation at the corresponding positions, so as to make the water tank more stable.

[0012] The depth of the top box cover at one end of the groove surface of the box body is less than the depth of the bottom groove at the other end below, thereby further improving the stability of the water tank, that is, when the concave and convex grooves are assembled correspondingly, the water tank is more stable after being assembled by gravity.

[0013] A liquid level sensor is provided on the inner wall of the bottom of one side of the box, and the liquid level sensor is fixed to a fixed groove on the inner wall of the bottom of one side of the box through a fixing plug, and a Hall switch sensor is provided at the corresponding part of the body of the liquid level sensor. Therefore, when the water level is lower than the liquid level sensor, the water in the box is disconnected from the liquid level sensor, and the liquid level sensor triggers the Hall switch sensor at the body to issue a water adding instruction.

[0014] The invention has a reasonable structural design, is easy to manufacture, disassemble and clean as a whole, has good stability after installation, is easy to replace the filter element, has a handle bracket with a handle, has good versatility, and can accurately detect the critical point of the liquid level, especially when it is inconvenient to manufacture and use; it is suitable for use as a water tank with a handle for a coffee machine, as well as a structural improvement of similar products.
