Description

Technical Field

[0001] This utility model relates to a mixing device, and more particularly to a portable mixing device. Background Technology

[0002] When conducting blood tests, mixing the sample is one of the key steps to ensure accurate test results. This process usually requires the use of a mixing device to homogenize the blood sample.

[0003] Current mixing devices are relatively large and are typically used in fixed locations such as laboratories, hospitals, schools, and research institutions, making them unsuitable for outdoor use or frequent changes in location. Therefore, there is an urgent need for a portable mixing device. Utility Model Content

[0004] The purpose of this invention is to provide a portable mixing device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The solution to the technical problem of this utility model is:

[0006] A portable mixing device includes: a folding plate comprising a left plate and a right plate rotatably connected to the right side of the left plate; a left box detachably connected to the top side of the left plate, wherein an elastic component is disposed within the left box, the elastic component having an elastic end that can elastically move in a left-right direction; a right box detachably connected to the top side of the right plate, wherein a motor is disposed within the right box, the motor driving a cam; and a slide, the left end of which passes through the left box and abuts against the elastic end, the right end of which passes through the right box and abuts against the cam, wherein the slide has multiple positioning grooves.

[0007] This technical solution has at least the following beneficial effects: During use, the left and right plates rotate to be on the same horizontal plane, the folding plate is in the unfolded state, and the left and right ends of the carriage are located inside the left and right boxes respectively. The container to be mixed is placed into the positioning groove, and the motor drives the cam to rotate. Since the right end of the carriage abuts against the outside of the cam, when the distal end of the cam rotates to abut against the right side of the carriage, the carriage moves to the left and elastically presses the elastic end to the left, increasing the elastic potential energy of the elastic component. When the distal end of the cam rotates away from the carriage, the elastic potential energy of the elastic component is released, and the elastic end pushes the carriage to the right, keeping the right end of the carriage abutting against the cam. When the proximal end of the outer periphery of the cam... When the slide is in contact with the cam, it moves to the right to the end of its stroke. As the cam rotates, it drives the slide to move back and forth, thus mixing the solution in the container. When the whole assembly needs to be stored and carried, the left and right boxes are detached from the left and right plates respectively, and the slide is moved out of the left and right boxes. At this time, the left and right plates can be rotated to bring them closer together, so that the folding plate is folded. This allows for easy handling and transfer of the left and right boxes, the slide, and the folding plate individually. Therefore, this utility model can not only achieve the function of mixing and shaking the solution, but also disassemble and store the whole assembly according to the needs of use, improving the flexibility and convenience of overall use.

[0008] As a further improvement to the above technical solution, sliding sleeves are respectively provided on the right side of the left box and the left side of the right box, and the left and right ends of the slide are slidably connected to the two sliding sleeves respectively. Sliding sleeves providing slidable connection for the slide are provided on the left and right boxes respectively. When both ends of the slide are inserted into the left and right boxes respectively, they slidably connect with the sliding sleeves in the left and right boxes, thus improving the stability and smoothness of the slide's left and right sliding.

[0009] As a further improvement to the above technical solution, a left box cover is detachably connected to the top side of the left box body. A left fixing groove is provided on the top right side of the left box body, and the left box cover presses and fixes one of the sliding sleeves in the left fixing groove. The left box body has a left fixing groove to avoid the sliding sleeve. During overall assembly, the left box body is first connected to the left plate, and the sliding sleeve is fitted onto the outer side of the left end of the slide. The left box cover is opened, and the sliding sleeve is placed into the left fixing groove. The left fixing groove facilitates the pre-positioning of the sliding sleeve. Then, the left box cover is connected to the left box body, and the left box cover presses and fixes the left fixing groove, making the connection quick and convenient.

[0010] As a further improvement to the above technical solution, a right box cover is detachably connected to the top side of the right box body, and a right fixing groove is provided on the top left side of the right box body. The right box cover presses and fixes one of the sliding sleeves in the right fixing groove. Similarly, a right fixing groove is provided on the right box body to avoid the sliding sleeve. During overall assembly, the right box body is first connected to the right plate, and the sliding sleeve is fitted onto the outer side of the right end of the slide. The right box cover is opened, and the sliding sleeve is placed into the right fixing groove. The right fixing groove facilitates the pre-positioning of the sliding sleeve. Then, the right box cover is connected to the right box body, and the right box cover presses and fixes the right fixing groove. The connection is quick and convenient.

[0011] As a further improvement to the above technical solution, the elastic component includes a fixed plate, a spring sheet, and a push rod. The fixed plate is connected to the left housing. One end of the spring sheet is connected to the fixed plate, and the other end of the spring sheet abuts against the push rod. The spring sheet has a tendency to press the push rod against the carriage. The push rod is the elastic end. The fixed plate is fixed in the left housing, providing a position for the installation and fixing of the spring sheet. At this time, the push rod acts as the elastic end that supports the carriage. The spring sheet abuts against the push rod, providing elastic force to the push rod. When the carriage moves to the left, the push rod can elastically compress and deform the spring sheet. After the pressure of the carriage on the push rod is removed, the spring sheet elastically returns to its original position, and the push rod is pushed to the right to reset.

[0012] As a further improvement to the above technical solution, there are two spring pieces, both of which are arc-shaped with opposite opening directions. These two arc-shaped spring pieces with opposite opening directions provide stable elastic support to the push rod, reducing the tilting or offset of the push rod when it moves against the carriage, thus further improving the stability of the push rod.

[0013] As a further improvement to the above technical solution, the left top side of the left plate is provided with first slide rails spaced apart along the front-back direction, and the front and rear sides of the left box are respectively provided with first slide grooves. The two first slide grooves extend to the left side of the left box, and the two first slide rails are slidably connected in the two first slide grooves. When the left box is connected to the left plate, the left box moves to the left on the left plate, so that the front and rear first slide rails on the left top side of the left plate slide into the two first slide grooves respectively. Since the right ends of the two first slide grooves do not penetrate to the right side of the left box, when the two first slide rails abut against the right ends of the two first slide grooves, the left box moves to the end of its stroke. At this time, the cooperation between the first slide rails and the first slide grooves can restrict the left box from detaching from the left plate upwards and to the left, realizing the quick installation of the left box. When it is necessary to disassemble the left box, it is only necessary to move the left box to the right, so that the first slide rails disengage from the first slide grooves.

[0014] As a further improvement to the above technical solution, the right top side of the right plate is provided with second slide rails spaced apart along the front-back direction, and the front and rear sides of the right box are respectively provided with second slide grooves. The two second slide grooves extend to the right side of the right box, and the two second slide rails are slidably connected in the two second slide grooves. Similarly, when the right box is connected to the right plate, the right box moves to the right on the right plate, so that the front and rear first slide rails on the right top side of the right plate slide into the two first slide grooves respectively. Since the left ends of the two first slide grooves do not penetrate to the left side of the right box, when the two first slide rails abut against the left ends of the two first slide grooves, the right box moves to the end of its stroke. At this time, by utilizing the cooperation of the first slide rails and the first slide grooves, the right box can be restricted from detaching from the right plate upwards and to the right, realizing the quick installation of the right box. When it is necessary to disassemble the right box, it is only necessary to move the right box to the left, so that the first slide rails disengage from the first slide grooves.

[0015] As a further improvement to the above technical solution, anti-slip pads are respectively connected to the bottom sides of the left and right plates. When the left and right plates are laid flat on a support surface such as a table, the anti-slip pads can increase the friction between them and the table surface, reducing the tendency for the left and right plates to shift relative to the support surface during operation, and improving the overall stability of use.

[0016] As a further improvement to the above technical solution, multiple protrusions are arranged around the center of the cam on its outer side. When the cam rotates, the multiple protrusions can rotate to abut against the slide, thereby increasing the frequency of the slide's movement and thus improving the efficiency of solution mixing.

[0026] Reference Figure 1 , Figure 2 and Figure 3A portable mixing device includes a folding plate, a left box 200, and a right box 300. The folding plate includes a left plate 110 and a right plate 120 rotatably connected to the right side of the left plate 110. The rotation axes of the left plate 110 and the right plate 120 extend in the front-back direction. The left plate 110 and the right plate 120 can be connected to each other via hinges. To allow the left plate 110 and the right plate 120 to be fully unfolded, clearance grooves can be provided at the rotational connection positions of the left plate 110 and the right plate 120, and inserts into these clearance grooves to rotatably connect the two plates. A hinge; a left box 200 is detachably connected to the top side of the left plate 110, and an elastic component is provided inside the left box 200, the elastic component having an elastic end that can move elastically in the left and right direction; a right box 300 is detachably connected to the top side of the right plate 120, and a motor is provided inside the right box 300, the motor driving a cam 320; the left end of the slide 400 passes through the left box 200 and abuts against the elastic end, the right end of the slide 400 passes through the right box 300 and abuts against the cam 320, and a plurality of positioning grooves 410 are provided on the slide 400.

[0027] As described above, during use, the left plate 110 and the right plate 120 rotate to be on the same horizontal plane, the folding plate is in the unfolded state, and the left and right ends of the slide 400 are located in the left box 200 and the right box 300 respectively. The container to be mixed is placed into the positioning groove 410, and the motor drives the cam 320 to rotate. Since the right end of the slide 400 abuts against the outside of the cam 320, when the distal end of the cam 320 rotates to abut against the right side of the slide 400, the slide 400 moves to the left and elastically presses the elastic end to the left, increasing the elastic potential energy of the elastic component. When the distal end of the cam 320 rotates away from the slide 400, the elastic potential energy of the elastic component is released, and the elastic end pushes the slide 400 to the right, so that the right end of the slide 400 remains abutting against the cam 320. When the proximal end of the outer periphery of the cam 320 abuts against the cam 320... When the slide 400 is in position, the slide 400 moves to the right to the end of its stroke. As the cam 320 rotates, it drives the slide to move back and forth, thereby mixing the solution in the container. When it is necessary to store and carry the whole thing, the left box 200 and the right box 300 are removed from the left plate 110 and the right plate 120 respectively, and the slide 400 is moved out of the left box 200 and the right box 300. At this time, the left plate 110 and the right plate 120 can be rotated to bring them closer together, so that the folding plate is in a folded state. This makes it easy to carry and transfer the left box 200, the right box 300, the slide 400 and the folding plate separately. Therefore, this utility model can not only realize the function of mixing and shaking the solution, but also disassemble and store the whole thing according to the needs of use, improving the flexibility and convenience of the whole use.

[0028] Naturally, the right side of the left box 200 and the left side of the right box 300 can be respectively provided with holes for the slide 400 to pass through. In order to make the slide 400 move more smoothly relative to the left box 200 and the right box 300, in this embodiment, the right side of the left box 200 and the left side of the right box 300 are respectively provided with sliding sleeves 420, and the left end and the right end of the slide 400 are slidably connected to the two sliding sleeves 420 respectively. The sliding sleeves 420 that provide sliding connection for the slide 400 are respectively provided on the left box 200 and the right box 300. When the two ends of the slide 400 are respectively inserted into the left box 200 and the right box 300, they are slidably connected with the sliding sleeves 420 in the left box 200 and the right box 300, thus improving the stability and smoothness of the slide 400 sliding left and right.

[0029] The sliding sleeve 420 can be directly fixed inside the left box 200. However, for the convenience of overall installation, the sliding sleeve 420 can be designed to be detached from the left box 200. Specifically, the left box 200 is detachably connected to the top side of the left box 200, and a left fixing groove is provided on the right side of the top of the left box 200. The left box 210 presses and fixes one of the sliding sleeves 420 in the left fixing groove. A left fixing groove is provided on the left box body 200 to avoid the sliding sleeve 420. During the overall assembly, the left box body 200 is first connected to the left plate body 110, and the sliding sleeve 420 is fitted onto the outer side of the left end of the slide 400. The left box cover 210 is opened, and the sliding sleeve 420 is placed into the left fixing groove. The left fixing groove can be used to conveniently pre-position the sliding sleeve 420. Then the left box cover 210 is connected to the left box body 200, and the left fixing groove is pressed and fixed by the left box cover 210. The connection is quick and convenient. In practical applications, the left cover 210 can be fixed to the left box body 200 by a snap-fit ​​connection or by screws or other connecting parts. In order to ensure that the sliding sleeve 420 is securely installed in the left fixing groove, multiple locking ribs can be provided on the outside of the sliding sleeve 420 to lock the inner and outer sides of the left box body 200. The locking ribs are located on the inner and outer sides of the left box body 200 respectively. When the sliding sleeve 420 is installed into the left fixing groove, the multiple locking ribs on the outside of the sliding sleeve 420 are locked onto the inner and outer sides of the left box body 200 respectively, so that the sliding sleeve 420 is more securely installed into the left fixing groove.

[0030] Similarly, in the right box 300, the sliding sleeve 420 can be directly fixed inside the right box 300. However, for the convenience of overall assembly and disassembly, it can be designed to be assembled and disassembled from the right box 300. Specifically, the right box 300 is detachably connected to the top side of the right box 300, and a right fixing groove is provided on the left side of the top of the right box 300. The right box 310 presses and fixes one of the sliding sleeves 420 in the right fixing groove. Similarly, a right fixing groove is provided on the right box body 300 to avoid the sliding sleeve 420. During the overall assembly, the right box body 300 is first connected to the right plate body 120, and the sliding sleeve 420 is fitted onto the outer side of the right end of the slide 400. The right box cover 310 is opened, and the sliding sleeve 420 is placed into the right fixing groove. The right fixing groove can be used to conveniently pre-position the sliding sleeve 420. Then the right box cover 310 is connected to the right box body 300, and the right box cover 310 is used to press and fix the right fixing groove. The connection is quick and convenient. In practical applications, the right cover 310 can be fixed to the right box body 300 by a snap-fit ​​connection or by screws or other connecting parts. In order to securely install the sliding sleeve 420 in the right fixing groove, multiple retaining ribs can be provided on the outside of the sliding sleeve 420 to lock the inner and outer sides of the right box body 300. When the sliding sleeve 420 is inserted into the right fixing groove, the multiple retaining ribs on the outside of the sliding sleeve 420 are locked into the inner and outer sides of the right box body 300, thus making the sliding sleeve 420 more secure when inserted into the right fixing groove.

[0031] The elastic component is mainly used to provide a rightward thrust to the slide 400, so that the right end of the slide 400 remains against the cam 320. Its structure can take many forms. For example, a spring can be provided inside the left housing 200, and the left end of the slide 400 can abut against the spring, pushing the slide 400 to the right towards the cam 320 via the spring. In this embodiment, the elastic component includes a fixed plate 510, a spring piece 520, and a push rod 530. The fixed plate 510 is connected inside the left housing 200. One end of the spring piece 520 is connected to the fixed plate 510, and the other end abuts against the push rod 530. The spring piece 520 has a tendency to press the push rod 530 against the slide 400. The push rod 530 is the elastic end. The fixing plate 510 is fixed inside the left box 200, providing a position for the installation and fixing of the spring piece 520. At this time, the push rod 530 serves as the elastic end that supports the slide 400. The spring piece 520 abuts against the push rod 530, providing elastic force to the push rod 530. When the slide 400 moves to the left, the spring piece 520 can be elastically compressed and deformed by the push rod 530. After the pressure of the slide 400 on the push rod 530 is removed, the spring piece 520 elastically returns to its original state, and the push rod 530 is pushed to the right to reset.

[0032] To increase the stability of the force applied by the spring to the push rod 530, the number of spring plates 520 can be increased, resulting in a more even force distribution on the push rod 530. Specifically, there are two spring plates 520, both of which are arc-shaped with opposite opening directions. These two arc-shaped spring plates 520 provide stable elastic support to the push rod 530, reducing the tilting or offset of the push rod 530 when it is pushed against the carriage 400 by the spring plates 520, thus further improving the stability of the push rod 530 in use.

[0033] There are several ways to detachably connect the left box 200 to the left plate 110. For example, the left box 200 can be connected to the left plate 110 by a snap-fit, or the left box 200 can be locked and fixed to the left plate 110 by screws or other connecting parts. In order to improve the convenience of connecting the left box 200 to the left plate 110, in this embodiment, the left top side of the left plate 110 is provided with first slide rails 111 at intervals along the front and rear direction, and the front and rear sides of the left box 200 are respectively provided with first slide grooves. The two first slide grooves extend to the left side of the left box 200, and the two first slide rails 111 are slidably connected in the two first slide grooves. When the left box 200 is connected to the left plate 110, the left box 200 moves to the left on the left plate 110, so that the front and rear first slide rails 111 on the top left side of the left plate 110 slide into the two first slide grooves respectively. Since the right ends of the two first slide grooves do not extend to the right side of the left box 200, when the two first slide rails 111 abut against the right ends of the two first slide grooves, the left box 200 moves to the end of its stroke. At this time, by utilizing the cooperation between the first slide rails 111 and the first slide grooves, the left box 200 can be restricted from moving upward and to the left out of the left plate 110, so as to realize the quick installation of the left box 200. When it is necessary to disassemble the left box 200, it is only necessary to move the left box 200 to the right so that the first slide rails 111 disengage from the first slide grooves.

[0034] Similarly, the right top side of the right plate 120 is provided with second slide rails 121 at intervals along the front and rear direction, and the front and rear sides of the right box 300 are respectively provided with second slide grooves. The two second slide grooves extend to the right side of the right box 300, and the two second slide rails 121 are slidably connected in the two second slide grooves. Similarly, when the right box 300 is connected to the right plate 120, the right box 300 moves to the right on the right plate 120, causing the front and rear first slide rails 111 on the top right side of the right plate 120 to slide into the two first slide grooves respectively. Since the left ends of the two first slide grooves do not extend to the left side of the right box 300, when the two first slide rails 111 abut against the left ends of the two first slide grooves, the right box 300 moves to the end of its stroke. At this time, by utilizing the cooperation between the first slide rails 111 and the first slide grooves, the right box 300 can be restricted from moving upward and to the right out of the right plate 120, thus achieving quick installation of the right box 300. When it is necessary to disassemble the right box 300, it is only necessary to move the right box 300 to the left, so that the first slide rails 111 disengage from the first slide grooves.

[0035] In some embodiments, anti-slip pads are respectively connected to the bottom sides of the left plate 110 and the right plate 120. When the left plate 110 and the right plate 120 are laid flat on a support surface such as a table, the anti-slip pads can increase the friction between them and the table surface, reducing the tendency for the left plate 110 and the right plate 120 to shift relative to the support surface during operation, thus improving overall stability.

[0036] The cam 320 pushes the slide 400 to the left by abutting against the slide 400 with its distal end. When the cam 320 has only one distal end, it needs to rotate one revolution to push the slide 400 once. To increase the frequency of pushing the slide 400, in this embodiment, multiple protrusions 321 are arranged around the center of the cam 320. The positions of the multiple protrusions 321 are the multiple distal ends of the cam 320. For example, there are three protrusions 321. When the cam 320 rotates, the multiple protrusions 321 can rotate to abut against the slide 400, thus increasing the frequency of pushing the slide 400 and improving the efficiency of solution mixing.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
