[0028] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the term "installation", "connection" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be direct connection, also can through the indirect connection of intermediate medium, can be the intercommunication of two elements. For ordinary skilled in the art, the specific meaning of the above-mentioned term in the utility model can be understood according of specific circumstances.

[0029] In the related art, the constant volume of the medium often depends on manual operation, which is low in efficiency and high in intensity, and the constant volume result is easily affected by human factors.

[0030] Reference is made below to Figure 1 And Figure 2 The constant volume device 1 according to the utility model embodiment is described.

[0031] As Figure 1 And Figure 2 Indicated, the constant volume device 1 according to the utility model includes a cup body 11, and the internal space of the cup body 11 is used to accommodate a constant volume body 12 and the medium to be constant volume.

[0032] The constant volume device 1 further includes the constant volume body 12, and the constant volume body 12 is arranged in the cup body 11 and defines a constant volume cavity 13 suitable for accommodating the medium with the cup body 11, and the constant volume cavity 13 is open towards the top of the cup body 11, so that the medium can be conveniently added therein. The constant volume body 12 can be moved relative to the cup body 11 in the height direction of the cup body 11 to adjust the volume of the constant volume cavity 13. By adjusting the position of the constant volume body 12 in the cup body 11, the volume of the constant volume cavity 13 can be adjusted. When the constant volume body 12 moves upwards, the volume of the constant volume cavity 13 decreases; on the contrary, when the constant volume body 12 moves downwards, the volume of the constant volume cavity 13 increases. Therefore, the volume of the constant volume cavity 13 can be adjusted as required to meet the constant volume requirements in different experiments or production processes.

[0033] In actual use, first, the required volume of the constant volume body 12 is determined according to the experimental or production requirements. Then, by adjusting the position of the constant volume body 12 in the cup body 11, the volume of the constant volume cavity 13 reaches the predetermined value. Next, the medium to be constant volume is added into the constant volume cavity 13 through the open mouth of the cup body 11 until the liquid surface of the medium reaches the top of the constant volume cavity 13 or the preset scale line. At this time, the constant volume operation can be completed.

[0034] Therefore, according to the constant volume device 1 of the utility model, by adjusting the position of the constant volume body 12 in the cup body 11, the volume of the constant volume cavity 13 can be adjusted, which improves the precision and efficiency of constant volume, and also reduces the labor cost and operation difficulty.

[0035] According to some embodiments of the utility model, as Figure 2 As shown, the constant volume body 12 includes a bottom plate 121, which is arranged in the cup body 11. The edge of the bottom plate 121 contacts the inner circumference of the cup body 11 to ensure sealing and prevent leakage of the medium in the constant volume cavity 13.

[0036] The constant volume body 12 also includes a side panel 122, which extends from the edge of the bottom panel 121 toward the top of the cup body 11. A constant volume cavity 13 is defined between the side panel 122, the bottom panel 121, and the cup body 11. The side panel 122 is movably engaged with the cup body 11. When the side panel 122 moves relative to the cup body 11, the height of the constant volume cavity 13 is changed, thereby adjusting the volume of the constant volume cavity 13. Due to the movable engagement between the side panel 122 and the cup body 11, the volume of the constant volume cavity 13 can be adjusted within a certain range, so that the constant volume device 1 can adapt to the constant volume requirements of different volumes, thereby improving its flexibility and practicality.

[0037] By providing the side panels 122 and movably cooperating with the cup body 11, not only is the volume of the constant volume chamber 13 flexibly adjustable, but the overall structural strength and stability of the constant volume body 12 are also enhanced. When a heating medium is required, the side panels 122 can also effectively insulate, reducing the effects of high temperatures on operators.

[0038] According to some embodiments of the present invention, a slide groove is formed between the side panel 122 and one of the cup body 11, and the slide groove extends along the height direction of the cup body 11, providing a track for the slider to slide. A slider is formed between the side panel 122 and the other of the cup body 11, and the slider is slidably arranged in the slide groove, thereby allowing the side panel 122 to move up and down relative to the cup body 11. A sliding matching relationship is formed between the slider and the slide groove, and the user can operate the side panel 122 to make the slider slide along a predetermined track in the slide groove, causing the side panel 122 to move up and down relative to the cup body 11, thereby changing the height and volume of the constant volume chamber 13.

[0039] The cooperation between the sliding groove and the slider can ensure the stability and accuracy of the side plate 122 during the movement, thereby meeting the demand for precise adjustment of the volume of the constant volume chamber 13.

[0040] According to some embodiments of the present invention, Figure 2 As shown, the groove wall of the chute is formed with a locking portion 111, and the slider is formed with a mating portion. The mating portion and the locking portion 111 cooperate with each other to lock the relative position of the cup body 11 and the constant volume body 12 when the slider slides to a preset position. When the slider slides along the chute and reaches the preset position, the mating portion and the locking portion 111 begin to interact. Through the cooperation of the mating portion and the locking portion 111, the slider is locked in a specific position in the chute, thereby locking the relative position between the cup body 11 and the constant volume body 12.

[0041] Through the mutual cooperation of the locking portion 111 and the cooperating portion, the user can lock the relative position between the cup body 11 and the volume setting body 12 after adjusting the volume of the volume setting cavity 13, so as to maintain the volume of the volume setting cavity 13 stable and unchanged.

[0042] According to some embodiments of the present application, one of the locking portion 111 and the cooperating portion is formed with a clamping groove, and the other of the locking portion 111 and the cooperating portion is configured as a clamping protrusion. The clamping protrusion and the clamping groove are matched, so that when the sliding block slides to the preset position, the clamping protrusion can be accurately embedded into the clamping groove to lock the relative position between the cup body 11 and the volume setting body 12. When the sliding block slides along the sliding groove and reaches the preset position, the clamping protrusion and the clamping groove interact, the clamping protrusion gradually approaches and is embedded into the clamping groove, realizing the locking of the relative position between the cup body 11 and the volume setting body 12, so as to maintain the volume of the volume setting cavity 13 stable and unchanged.

[0043] According to some embodiments of the present application, as shown in Figure 2 The volume setting device 1 further comprises an elastic supporting member 14, which is arranged in the cup body 11. One end of the elastic supporting member 14 is connected to the bottom wall of the cup body 11, and the other end of the elastic supporting member 14 is connected to the volume setting body 12, so that the elastic supporting member 14 can effectively support the volume setting body 12 and provide necessary buffering action when needed. The elastic supporting member 14 has the characteristics of telescopic deformation, so that the length of the elastic supporting member 14 can change according to the action of external force, so as to adapt to the movement of the volume setting body 12 in the cup body 11.

[0044] According to some embodiments of the present application, as shown in Figure 2 The elastic supporting member 14 is configured to be arranged in multiple. Multiple elastic supporting members 14 can provide multi-point support between the volume setting body 12 and the cup body 11, thereby reducing the burden of a single elastic supporting member 14, and increasing the stability and reliability of the support. The multiple elastic supporting members 14 arranged in multiple can disperse the pressure of the volume setting body 12 on the cup body 11, so that the supporting force is more uniform.

[0045] According to some embodiments of the present application, as shown in Figure 2 The cup body 11 is provided with a locking portion 111, which is configured to be arranged in multiple at different heights of the cup body 11. Therefore, the locking portion 111 can provide locking function at multiple different height positions, so that the volume setting body 12 can cooperate with different locking portions 111 to be fixed at different positions in the cup body 11. When the volume setting body 12 is fixed at different height positions, the volume of the volume setting cavity 13 will change accordingly. By adjusting the height position of the volume setting body 12 and cooperating and locking the volume setting body 12 with the locking portion 111 at a specific height position, the volume of the volume setting cavity 13 can be adjusted according to actual needs to adapt to different volume setting requirements.

[0046] According to some embodiments of the present invention, Figure 1 As shown, the cup body 11 is provided with an indicator 112, which can indicate the volume size of the constant volume chamber 13 according to the relative position of the cup body 11 and the constant volume body 12. The indicator 112 can be a scale line, a digital mark, a color code or any other element that can clearly indicate the position or size change. There is a certain association or correspondence between the indicator 112 and the constant volume body 12, so that when the constant volume body 12 moves or is fixed in a certain position in the cup body 11, the indicator 112 can reflect the position change of the constant volume body 12. Based on the relative position of the cup body 11 and the constant volume body 12, the indicator 112 can give intuitive information about the current volume size of the constant volume chamber 13. For example, if the constant volume body 12 is fixed on a specific scale line, the number or mark corresponding to the scale line represents the current volume of the constant volume chamber 13.

[0047] By providing the indicator portion 112 , the volume of the constant volume chamber 13 can be easily understood, thereby improving the convenience of use of the constant volume device 1 .

[0048] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the volume control device 1 also includes a handle 15, which is a structure that is convenient for gripping. The handle 15 facilitates operation of the volume control device 1, such as moving and pouring. The handle 15 is connected to the outer peripheral wall of the cup body 11 and extends radially along the cup body 11. This provides a comfortable grip angle and ample gripping space, making it easy for the user to pick up, move, and manipulate the volume control device 1.
