[0033] A handle 4 is provided on one side of the handle base 41, and a mounting platform 421 is provided on the side of the handle 4 close to the cup body 2. The mounting platform 421 is a boss protruding from the top of the handle 4 toward the cup body 2. The outer diameter of the boss is smaller than the outer diameter of the upper end of the handle, and the boss is located at the center of the upper end of the handle, thereby forming a limiting step 4210 at the upper end of the handle, and the boss is provided with an upwardly protruding edge 4212. The edge 4212 encloses a mounting cavity 4213 with an upper opening, and the edge 4212 is also provided with a slot. In this embodiment, the slots are two relatively arranged card slots 4214, and a support plate is provided at the bottom of the accommodating cavity 4213. A wire hole 4215 is provided on one side of the support plate, and a threaded column 422 is provided at the bottom of the handle 4.

[0034] When installing the handle 4, first place the sensing element 6 into the mounting cavity 4213 from the top opening of the mounting cavity 4213. The sensing element 6 is supported by the support plate at the bottom of the mounting cavity 4213. The lead 61 connected to the sensing element 6 extends out of the mounting cavity 4213 from the wire hole 4215 on one side of the support plate. Then, the handle 4 with the sensing element 6 placed in it is fixed to the handle base 41, and the ring 8 is placed on the mounting platform 421. The mounting platform 421 at the top of the handle is inserted into the mounting tube 411 at the top of the handle base 41. The front end wall 4211 of the mounting platform 421 abuts against the front wall 416 of the mounting tube 411. The limiting step 4210 of the handle 4 presses the ring 8 against the mounting wall 410. The top wall 4111 of the mounting tube 411 abuts against the top of the surrounding edge 4212, and closes the opening at the top of the mounting cavity 4213. Furthermore, the slot 4214 on the edge 4212 of the mounting platform 421 partially extends into the through hole 413 on the bottom wall of the mounting tube 411. The latch portion 72 of the clip 7 is inserted from bottom to top into the through hole 413. One end of the latch portion 72 abuts against the wall of the through hole 413, while the other end abuts against the wall of the slot 4214. The main body 71 of the clip 7 abuts against the positioning portion 414. The circular hole in the main body 71 corresponds to the threaded hole in the positioning portion 414. A screw passes through the circular hole and is threadedly connected to the threaded hole to secure the clip 7, thereby securing the handle base 41 to the upper end of the handle. At this point, the latch portion 72 of the clip 7 and the limiting step 4210 together clamp the mounting wall, wherein the latch portion 72 is indirectly abutted against the mounting wall via the mounting tube. Then, another ring is put on the bottom end of the handle, and the threaded column 422 at the bottom of the handle 4 is matched with the through hole 417 at the bottom of the handle base 41. The screw passes through the through hole 417 and is threadedly connected to the threaded column 422 to fix the handle base 41 and the lower end of the handle 4, and the ring is clamped. At this time, the fixation of the sensing element 6 and the handle 4 is completed.

[0035] Then, snap the hook 412 at the top of the handle base 41 onto the top edge of the cup body 2. The mounting post 418 at the bottom of the handle base 41 aligns with the threaded post on one side of the base 3. Screws are inserted through the through-hole in the center of the mounting post 418 and connected to the threaded post to secure the handle base to the base 3. The leads of the sensing element 6 extend from the mounting cavity 4213 through the wire hole 4215 into the accommodating cavity 5. They then run down the accommodating cavity 5, through the wire entry hole, into the base 3, and connect to the power board inside the base 3.

[0036] In this embodiment, a handle and a fastener are respectively provided on both sides of the mounting wall of the handle base, the handle mounting platform passes through the mounting wall, the pin portion of the fastener is inserted into the slot of the mounting platform, and the mounting wall is clamped together by the pin portion of the fastener and the limiting step of the handle to achieve the fixation of the handle. In this scheme, the handle is fixed by plugging and cooperating with the fastener. Compared with the method in the prior art where the handle and the shell are directly fixed by screws, on the one hand, the fastener does not have the problem of moisture and rust. On the other hand, if only screws are used for fixation, when the common screw stripping phenomenon occurs, the handle fixed only by the screws will become loose, affecting the normal use of the machine. The fastener fixes the handle by plugging and cooperating with the mounting platform and pressing against the mounting wall. At this time, the fixation of the handle is achieved by the cooperation of multiple components, which is more stable than the single screw fixation method.

[0037] In this utility model, the mounting tube can provide axial support for the mounting platform, resulting in a larger force-bearing area between the mounting tube and the mounting platform, a more stable support effect, and preventing axial shaking of the mounting platform. The mounting tube is open at one end and closed at the other end. The front end wall of the mounting platform abuts the closed end of the mounting tube, which can be used to assist in positioning the mounting platform based on the limit step. The handle can be pre-positioned in the installation position to prevent the handle from colliding with the cup body during installation.

[0038] A decorative ring is provided on the mounting platform, and the limiting step is clamped with the mounting wall through the decorative ring. The decorative ring can cover the connection gap between the mounting platform and the mounting wall, thereby improving the appearance.

[0039] In order to further protect the sensing element, the ring can be made of an elastic part, preferably a silicone ring. The elastic part can be deformed by extrusion to better seal the gap between the handle and the mounting tube, preventing water from flowing through the gap into the mounting cavity, and protecting the sensing element from short circuit failure caused by contact with water.

[0040] In this embodiment, the through hole on the bottom wall of the mounting tube can be set close to the mounting wall. At this time, the pin portion of the fastener passes through the through hole and is inserted into the slot. Part of the pin portion protrudes out of the slot, and the pin portion protruding out of the slot directly presses against the inner surface of the mounting wall.

[0041] Of course, the support plate used to support the sensing element in this embodiment can also be a support rib arranged on the inner wall of the surrounding edge. Support ribs parallel to the surrounding edge can be arranged on the inner walls of two opposite surrounding edges to support the sensing element, or support ribs connecting the two surrounding edges can be arranged between the two opposite surrounding edges. The specific structure of the support ribs is not limited. By setting the support ribs, while supporting the sensing element, wire holes can also be formed between the support ribs.

[0042] In another embodiment, the mounting cavity can be formed by recessing the front wall of the mounting platform, which is adjacent to the cup, into the interior of the mounting platform. In this case, an opening is formed in the front wall of the mounting platform. After the sensing element is placed into the mounting cavity through the opening, the mounting platform is inserted into the mounting tube. The front wall of the mounting tube abuts against the front wall of the mounting platform, sealing the opening and retaining the sensing element within the mounting cavity. In this case, a wire hole is provided in the bottom wall of the mounting cavity, and the wiring harness of the sensing element extends through the wire hole into the accommodating cavity.

[0043] Of course, the mounting cavity can also be formed by the side walls on both sides of the front end wall of the mounting platform being recessed into the mounting platform. In this case, after the mounting platform is inserted into the mounting tube, the side walls on both sides of the front wall of the mounting tube abut against the side walls of the mounting platform, and the openings of the side walls of the mounting platform are closed to limit the sensing element in the mounting cavity.

[0044] In the above embodiments, the cup body can be a glass cup, and a shock-absorbing member can be arranged between the hook of the handle seat and the edge of the cup. The preferred shock-absorbing member is a silicone member. The shape of the shock-absorbing member is similar to the shape of the hook, which can achieve a soft connection between the hook and the cup body. When the machine is running, it avoids hard collision between the hook and the cup body, which is conducive to reducing noise and can also prevent the hook from scratching the cup body.

[0045] In another embodiment, a sticker may also be affixed to the convex edge of the handle base to shield the interior of the accommodating cavity, preventing the wiring harness inside the accommodating cavity from being visible through the glass, thereby ensuring that the overall appearance of the machine is simple and beautiful.

[0046] In another embodiment, the cup body includes an inner cup and an outer cup 21 sleeved outside the inner cup. Figure 8 The inner cup can be a glass or metal cup, and the outer cup is a plastic shell that surrounds the inner cup. The plastic shell can also enclose the motor and power board.

The mounting shell can also be a base located below the cup body. A through hole is provided on the side wall of the base. The mounting wall is the side wall of the base. The handle mounting platform passes through the through hole and extends from the outside of the base into the inside of the base. A fastener is provided inside the base. The fixing method is as described above.

[0048] The fastener can be fixed directly to the mounting platform, with a threaded hole provided on the mounting platform, and a screw passing through the main body and threadedly connected to the threaded hole to fix the fastener to the mounting platform. In this case, the latch portion of the fastener can be inserted into the slot from top to bottom or from bottom to top. When the fastener is inserted into the slot from top to bottom, screw fixation is not required, and the main body is supported on the mounting platform to fix the fastener. The end of the latch end of the fastener can also be provided with a spring catch, and a catch position is provided on the top wall or the slot wall of the mounting platform. The catch position can be a rib or a protrusion. The latch end of the fastener is inserted into the slot from bottom to top until the spring catch hooks on the catch position. The spring catch can also be directly fastened to the edge of the slot, that is, the spring catch is directly fastened to the top wall of the mounting platform. The fastener is fastened to the mounting platform by the spring catch. The slot can also be set in the horizontal direction, and the top wall and bottom wall of the mounting platform are relatively provided with horizontal slots. The pin of the fastener is inserted into the slot horizontally in the horizontal direction, and one pin of the fastener is held in the slot on the top wall of the mounting platform. At this time, the component for fixing the fastener can also be eliminated, and the fastener can be fixed by holding the mounting platform.

[0049] The latching member may also be a latch member, comprising a main body and a latch extending downwardly from the main body. In this case, the slot is a through-hole provided in the mounting platform. The latch is passed through the through-hole from top to bottom, the main body rests on the mounting platform, and a portion of the latch member extends from the mounting platform through the through-hole.
