Description

Technical Field

[0001] The utility model relates to the technical field of biochemical experimental equipment, in particular to a water bath device with an oscillation function. Background Art

[0002] Water bath is mainly used as heating equipment for distillation, drying, concentration, and incubation of chemicals or biological products in laboratories. It can also be used for constant temperature heating and other temperature control experiments. It is an essential tool for biology, genetics, virus, aquaculture, environmental protection, medicine, health, laboratories, analysis rooms, education and scientific research.

[0003] Water baths are also used in the pharmaceutical industry. For example, they are usually used when the medicines need to be heated and mixed during the pharmaceutical process. However, some medicines need to be shaken during the heating process to ensure that the medicines are fully mixed and then fully react. However, traditional water baths do not have an oscillation function, so the operator can only hold the conical flask manually and shake the conical flask while heating the medicine in the water bath, which is time-consuming and laborious.

[0004] In order to solve the disadvantage that the traditional water bath has no oscillation function, an oscillation device is also added to the water bath in the prior art, and the conical flask is oscillated by the oscillation device, so that the operator can free his hands; for example, the patent document with application number CN201821101414.3 discloses a water bath constant temperature oscillator, whose structure includes a shell and a water bath fixedly installed in the shell, the shell and the water bath are both provided with openings on the top, a support block is fixedly installed on one side of the top of the shell, and the support block is located on one side of the water bath, a column is fixedly installed on the top of the support block, an oscillation frame is slidably installed on the column, a clamp is provided at one end of the oscillation frame, and the clamp is located above the water bath, a reagent bottle is fixedly clamped on the clamp, and the bottom end of the reagent bottle extends into the water bath. The water bath constant temperature oscillator in the utility model can make the reagent bottle continuously oscillate up and down through the continuous rotation of the cam.

[0005] Although the above patent can make the water bath have an oscillation function, the reagent bottle is in an up and down oscillation motion mode. When an open conical bottle is used, the medicine in the conical bottle may spill out of the conical bottle due to the oscillation, causing the loss of medicine and contaminating the water bath. Utility Model Content

[0006] The utility model aims to provide a water bath device with an oscillation function, so as to solve the technical problem that the water bath oscillation device in the prior art mentioned above oscillates up and down, so that the medicine is spilled out of the conical bottle, causing the loss of medicine and polluting the water bath.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a water bath device with an oscillation function, including a water bath body, a clamp for fixing a conical flask, a rectangular oscillation frame is provided in the water bath body, the clamp is laterally fixed on the inner side of the oscillation frame, an oscillation spring is provided between the oscillation frame and the water bath body, the oscillation frame is suspended in the water bath body through the oscillation spring, an oscillation rod is fixedly connected to the outer side wall of the oscillation frame, and a driving motor that can drive the oscillation rod to move laterally is provided on the outer side of the water bath body.

[0008] The beneficial effects of this embodiment are:

[0009] 1. The vibration mode of the oscillation device in the prior art drives the conical flask to vibrate by moving up and down, so that the medicine in the conical flask may spill out of the conical flask due to the vibration, causing medicine loss and contaminating the water bath. However, the present application is designed with an oscillation frame, on which an oscillation spring and an oscillation rod are horizontally arranged, so that the vibration of the oscillation frame is horizontal, avoiding the risk of medicine spilling out.

[0010] Furthermore, the driving motor includes an output shaft, and a cam is provided at the end of the output shaft.

[0011] Furthermore, a push block is provided on the end surface of the oscillating rod, and a groove with a width equal to the thickness of the cam is opened on the push block. The width of the groove is equal to the thickness of the cam, so that the cam can be stuck in the groove and is not easy to fall out.

[0012] Furthermore, the clamp includes a rotatable movable semicircular plate and a threaded pin that can fix the movable semicircular plate. The clamp uses the movable semicircular plate to achieve a size-adjustable function and can correspond to conical bottles of different sizes.

[0013] Furthermore, the oscillation spring is a thick wire spring, which has a certain rigidity and can provide lateral support for the oscillation frame.

[0014] Furthermore, oscillation rods and motors are respectively provided on the adjacent two side walls of the water bath body. Two sets of oscillation rods and motors are provided to drive the oscillation frame to oscillate. The oscillation rods and motors can be used together to realize the oscillation mode in which the mold operator oscillates in circles with his wrist, and the oscillation effect is better.

[0019] The following is further described in detail through specific implementation methods:

[0020] The figure marks in the drawings of the specification include: lid 1, water bath body 2, display screen 21, control button 22, drive motor 23, cam 231, oscillation frame 3, clamp 31, movable semicircular plate 311, rotating shaft 312, fixing block 313, threaded pin 314, oscillation rod 32, pushing block 321, oscillation spring 4, second motor 223.

[0021] Example 1

[0022] As attached Figures 1 to 3 As shown: a water bath device with an oscillation function, including a water bath body 2, the water bath body 2 is provided with a lid 1 that can cover the water bath body 2, the lid 1 can completely cover the water bath, prevent heat loss when the temperature rises, and can reach the set temperature faster.

[0023] A display screen 21 and a control button 22 are provided on the water bath body 2. The display screen 21 can display the water temperature, oscillation and other states of the water bath body 2, so that the technicians can understand the current parameters at any time during the experiment. A control button 22 is provided below the display screen 21, and the control button 22 can adjust the target water temperature and oscillation state of the water bath.

[0024] An oscillation frame 3 is arranged inside the water bath body 2. The oscillation frame 3 is a rectangular frame structure without a cover and a bottom formed by welding four steel plates. The oscillation frame 3 is connected to the water bath body 2 by an oscillation spring 4. One end of the oscillation spring 4 is welded to the inner side of the water bath body 2, and the other end is welded to the outer side of the oscillation frame 3. The oscillation spring 4 is a thick wire spring, which can provide rigidity to support the oscillation frame 3 laterally. Therefore, 6 groups of springs are arranged outside the oscillation frame 3 to suspend the oscillation frame 3 in the water bath without contacting the bottom of the water bath. Figure 1 The direction is the description direction. An oscillation rod 32 is welded on the right side of the oscillation frame 3. A circular hole is opened on the right side wall of the water bath body 2 at a position corresponding to the oscillation rod 32. The diameter of the circular hole is larger than the diameter of the oscillation rod 32. The right end of the oscillation rod 32 passes through the circular hole and extends out of the water bath body 2. A driving motor 23 is arranged on the right side wall of the water bath body 2. The output shaft of the driving motor 23 and the end face of the oscillation rod 32 just contact each other. Figure 2As shown, a cam 231 is installed on the output shaft of the driving motor 23, a push block 321 is welded on the end surface of the oscillation rod 32, a groove is formed on the push block 321, and the width of the groove is consistent with the thickness of the cam 231, and the cam 231 is just stuck on the push block 321. Therefore, when the driving motor 23 is started, the cam 231 starts to rotate, and due to the change in the diameter of the cam 231, the cam 231 will periodically squeeze the push block 321 to the left, and the force of squeezing the push block 321 is transmitted to the oscillation frame 3 by the oscillation rod 32, so that the oscillation frame 3 oscillates.

[0025] A plurality of fixtures 31 are staggeredly arranged on the inside of the oscillation frame 3, and the fixtures 31 include a support rod, a movable semicircular plate 311, a rotating shaft 312, a fixed block 313, and a threaded pin 314. The support rod is directly staggered and horizontally welded on the inside of the oscillation frame 3, and a rotating shaft 312 is hinged on the end face of the support rod, and two movable semicircular plates 311 are sleeved on the rotating shaft 312, and the two movable semicircular plates 311 are relatively arranged to form a circle in the middle that can clamp the bottleneck of the conical bottle. Because the movable semicircular plate 311 is sleeved on the rotating shaft, the movable semicircular plate 311 can be rotated by the rotating shaft 312, and a fixed block 313 is welded on the end face of the movable semicircular plate 311, and a hole is horizontally opened on the fixed block 313, and a threaded pin 314 is sleeved in the hole, so the threaded pin 314 can be used to lock and fix the movable semicircular plate 311.

[0026] Example 2

[0027] like Figure 4 As shown, the difference between Example 2 and Example 1 is that Example 2 is provided with two motors, namely, a driving motor 23 and a second motor 223, and the groove provided on the push block 321 is larger than the thickness of the cam 231. When it is running, the cams on the two motors are controlled to cooperate with the oscillation rod. The driving motor 23 first drives the oscillation rod to move to the left, and then the second motor 223 drives the oscillation rod forward, so that the oscillation frame makes an elliptical trajectory for oscillation motion, which can simulate the operator holding a conical flask in a water bath and heating it, and using the wrist to draw circles to oscillate the medicine, so that the experimental oscillation effect is good.

[0028] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
