Technical Field

[0001] The utility model relates to the technical field of peristaltic pumps, in particular to an extrusion component, a pump head structure and a peristaltic pump. Background Art

[0002] The pump head structure of the peristaltic pump in the prior art generally includes a hose and an extrusion structure for extruding the hose. The existing structure of the extrusion structure includes: a triangular main body sleeved on the motor shaft, and three extrusion bearings respectively arranged at the three corner positions of the triangular main body; wherein the triangular main body is generally made of plastic, and the extrusion bearings are made of metal or alloy. Such an extrusion structure requires assembly grooves to be opened at the three corner positions of the triangular main body to install the extrusion shaft. The pump body structure itself is relatively complex with the extrusion structure arranged in this way, and the assembly process of the pump body structure is also relatively complex. In addition, the volume of the pump head installed with the extrusion structure is also relatively large, which affects the installation space occupied by the entire pump body structure.

[0061] In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the utility model. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the utility model. In addition, for clarity and brevity, the description of known functions and structures is omitted.

[0062] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0063] The terms "first", "second", etc. in the specification and claims of the present utility model are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0064] The following is combined with Figure 1 to Figure 2 As shown, the extrusion component provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0065] Example 1

[0066] Reference Figure 1 As shown, the embodiment of the utility model provides an extrusion component, including:

[0067] Main body 1;

[0068] at least one extrusion portion 2, wherein the extrusion portion 2 is formed on a side surface of the main body 1, protrudes and extends along a radial direction of the main body 1, and is integrally formed with the main body 1;

[0069] The side surface of the main body 1 and the side surface of the extrusion portion 2 are combined to form a contact surface.

[0070] In this specific embodiment of the utility model, at least one extrusion portion 2 is formed on the side of the main body 1 along the radial direction of the main body, and the extrusion portion 2 is used to squeeze the elastic hose to be matched when the extrusion component rotates, so as to achieve the fluid flowing out of the elastic hose. Here, the extrusion portion 2 and the main body 1 are an integrally formed structure, which simplifies the complexity of setting multiple extrusion bearings to achieve extrusion in the related art, and can also enhance the strength of the extrusion component.

[0071] It should be noted that the side surfaces of the main body 1 and the extrusion portion 2 of the embodiment of the utility model are combined to form a contact surface, which is used in conjunction with the elastic hose to be matched. For example, the elastic hose half surrounds the main body 1 and the extrusion portion 2. In the initial state, no extrusion occurs between the elastic hose and the extrusion portion 2. During the rotational movement of the extrusion component, extrusion occurs between the elastic hose and the extrusion portion 2, thereby achieving the effect of flowing out the fluid in the elastic hose.

[0072] Optionally, the main body 1 is a columnar structure, and the extrusion portion 2 is on the side of the main body 1 and protrudes and extends along the radial direction of the main body 1 to form a semicircular columnar structure.

[0073] In particular, the number of the extrusion parts 2 can affect the flow rate of the elastic hose to be matched. Preferably, the number of the extrusion parts 2 is two, and the positions of the two extrusion parts 2 are arranged oppositely.

[0074] Optionally, the number of the extrusion parts 2 is three, and the positions of the three extrusion parts 2 are arranged at equal intervals.

[0075] The embodiment of the utility model does not limit the number of the extrusion parts 2, which can be set according to actual needs and are not limited to this.

[0076] Optionally, the extrusion component of the utility model further includes:

[0077] The shaping portion 3 extends on the side surface of the main body 1 to form a clamping space for accommodating the elastic hose, and the shaping portion 3 is integrally formed with the main body 1 .

[0078] In the embodiment of the utility model, since the inner diameter of the elastic hose is relatively small, in order to prevent the extrusion part from causing the hose to flatten when squeezing the elastic hose and affecting the flow rate, the utility model extends a clamping space on the side of the main body 1, and the clamping space is used to clamp the hose to prevent the non-extrusion section of the hose from flattening, so that the hose remains in a round tube shape (i.e., reshaped), which can ensure that the elastic hose increases the fluid flow rate while reducing the inner diameter.

[0079] It can also be understood that, due to the design of the shaping portion 3, the inner diameter of the elastic hose can be made smaller without affecting the fluid flow rate, while also reducing the volume of the pump head structure.

[0080] Furthermore, the inner diameter of the clamping space of the shaping part 3 for accommodating the elastic hose can be selected to be between 1.8 mm and 3.8 mm. The reduction of the inner diameter of the elastic hose is also conducive to reducing the overall volume of the pump head. For example, by using the extrusion component of the utility model, the fluid flow rate of the elastic hose clamped by the shaping part 3 can be maintained at 20.9 ml / min to 23.1 ml / min, preferably at 22 ml / min.

[0081] Furthermore, the shaping part of the utility model comprises:

[0082] Two clamping blocks 31 extending in the radial direction are provided on the side surface of the main body 1 . The two clamping blocks 31 are arranged opposite to each other to form the clamping space, and two opposite inner side surfaces of the two clamping blocks 31 are formed into arc surfaces.

[0083] It should be noted that the two opposite inner side surfaces of the two clamping blocks are arc surfaces, so as to form a C-shaped clamping space for clamping the elastic hose while keeping the hose in a round tube shape.

[0084] In particular, the number of the shaping parts 3 can be one or more, and the present invention does not limit this. Accordingly, each shaping part 3 is correspondingly provided with the two clamping blocks 31 .

[0085] Optionally, in the radial direction, the cross-section of the clamping block 31 is in at least one of a triangle, a trapezoid, a sector, a semicircle, and an irregular shape.

[0086] It should be understood that in this embodiment, when one shaping portion is provided, the shape of the cross section of the corresponding clamping block is at least one of a triangle, a trapezoid, a fan, a semicircle, an irregular shape or other shapes; when at least two shaping portions are provided, the shape of the cross section of the clamping block corresponding to each shaping portion may be the same or different.

[0087] It should be noted that due to the different positions of the shaping part, in a closed pump head structure, the shapes of the cross sections of the clamping blocks at different positions may be different. Therefore, the installation position of the shaping part can be represented by the shapes of the cross sections of different clamping blocks, which is beneficial to improving the assembly time of the extrusion components.

[0088] Optionally, the extrusion component is further provided with a first motor shaft mounting hole 4 penetrating the main body 1 in the axial direction of the main body 1;

[0089] Wherein, the axial direction is perpendicular to the radial direction.

[0090] In an embodiment of the utility model, a first motor shaft mounting hole 4 is provided through the main body 1 in the axial direction of the main body 1, and the first motor shaft mounting hole 4 is used to set or assemble the motor shaft. The cross-sectional shape of the first motor shaft mounting hole 4 can be D-shaped, circular, triangular, square or other shapes, and the first motor shaft mounting hole 4 needs to be adapted to the cross-sectional shape of the motor shaft to be installed.

[0091] Example 2

[0092] Reference Figure 2 As shown, the embodiment of the utility model further provides an extrusion component, comprising:

[0093] At least two groups of extrusion components 5, each group of the extrusion components 5 includes: a main body; at least one extrusion part, the extrusion part is formed on the side of the main body, protrudes and extends along the radial direction of the main body, and is integrally formed with the main body; wherein the side of the main body and the side of the extrusion part are combined to form a contact surface.

[0094] Furthermore, the central axes of each group of the extrusion components 5 are arranged on the same straight line, and at least two groups of the extrusion components 5 are integrally formed; wherein the axial direction of the extrusion components 5 is perpendicular to the radial direction.

[0095] It is understandable that the two groups of extrusion components 5 may also be split structures, and the present invention does not limit this.

[0096] In the embodiment of the utility model, the specific structure of each group of extrusion components 5 is the same as the structure of the extrusion component in Example 1, which will not be repeated here. The difference is that the utility model superimposes at least two groups of extrusion components 5 together in the axial direction, and at least two groups of extrusion components 5 are integrally formed. The utility model uses an extrusion component of multiple groups of extrusion components 5, which can increase the fluid flow rate. Here, the axial arrangement of multiple groups of extrusion components 5 is arranged on the same straight line, which can avoid large deviations in the radial direction after the multiple groups of extrusion components 5 are superimposed, and the space is occupied only in the axial direction, which minimizes the installation space occupied by the multiple groups of extrusion components 5, and ensures that the extrusion component in this embodiment has a smaller volume. In addition, the one-piece molding method can facilitate the manufacture and assembly of the pump head structure.

[0097] Optionally, the number of the at least two groups of extrusion components 5 is between two and five. Preferably, the two groups of extrusion components 5 are arranged to be stacked and integrally formed in the axial direction.

[0099] A first extrusion assembly and a second extrusion assembly disposed adjacent to each other;

[0100] The extrusion portion of the first extrusion assembly and the extrusion portion of the second extrusion assembly are staggered in the axial direction.

[0101] In an embodiment of the utility model, one of any two adjacent extrusion assemblies in at least two groups of extrusion assemblies is a first extrusion assembly, and the other is a second extrusion assembly. Since each group of extrusion assemblies includes at least one extrusion portion, from an axial top-down perspective of the extrusion assembly, the extrusion portion of the first extrusion assembly and the extrusion portion of the second extrusion assembly will not completely overlap, that is, the extrusion portion of the first extrusion assembly and the extrusion portion of the second extrusion assembly are staggered in the axial direction.

[0102] In one implementation, the number of extrusion parts of the first extrusion assembly is the same as the number of extrusion parts of the second extrusion assembly. For example, the extrusion part of the first extrusion assembly includes two extrusion parts, and the extrusion part of the second extrusion assembly includes two extrusion parts, wherein in the axial direction, the two extrusion parts of the first extrusion assembly and the two extrusion parts of the second extrusion assembly are staggered.

[0103] In another implementation, the number of extrusion parts of the first extrusion assembly is different from the number of extrusion parts of the second extrusion assembly. For example, the first extrusion assembly includes one extrusion part, and the second extrusion assembly includes two or three extrusion parts, and the extrusion parts of the first extrusion assembly and the extrusion parts of the second extrusion assembly are staggered.

[0104] In particular, the number of at least two groups of extrusion assemblies is preferably two groups of extrusion assemblies. Each extrusion assembly includes two extrusion parts and a shaping part, the two extrusion parts are arranged opposite to each other, the two extrusion parts are in a preset radial direction, and in the axial direction of the extrusion assembly (perpendicular to the preset radial direction), the two groups of extrusion assemblies are preferably orthogonally distributed, that is, the preset radial direction of the first group of extrusion assemblies in the two groups of extrusion assemblies is perpendicular to the preset radial direction of the second group of extrusion assemblies.

[0105] Optionally, each group of the extrusion components 5 further includes:

[0106] A shaping portion, the shaping portion extending on the side of the main body to form a clamping space for accommodating the elastic hose, and the shaping portion is integrally formed with the main body;

[0107] Wherein, the shaping part comprises:

[0108] Two clamping blocks are provided on the side of the main body portion and extend in the radial direction. The two clamping blocks are arranged opposite to each other to form the clamping space, and two opposite inner side surfaces of the two clamping blocks are formed into arc surfaces.

[0109] It should be noted that the structures of the shaping part and the clamping block of the shaping part in the embodiment of the utility model are the same as the structural scheme of the shaping part and the clamping block of the shaping part in the above-mentioned embodiment 1, and will not be repeated here.

[0110] Optionally, the cross-section of the clamping blocks in each group of shaping parts has a shape of at least one of a triangle, a trapezoid, a fan, a semicircle, and an irregular shape.

[0111] Optionally, the extrusion component is further provided with a second motor shaft mounting hole 6 in the axial direction of the main body, which penetrates the main body of the at least two groups of extrusion assemblies 5.

[0112] In the embodiment of the utility model, the central axis of each group of extrusion components 5 is set on a straight line, so the straight line can also represent the axis of any group of extrusion components 5, wherein on the straight line, a second motor shaft mounting hole 6 is set through all the extrusion components 5, and the second motor shaft mounting hole 6 is used to set or assemble the motor shaft, that is, the utility model can pass all the extrusion components 5 through a motor shaft to complete the rotation of the one-piece extrusion component.

[0113] It should be noted that the cross-sectional shape of the second motor shaft mounting hole 6 of the present invention can be D-shaped, circular, triangular, square or other shapes, and the second motor shaft mounting hole 6 must be compatible with the cross-sectional shape of the motor shaft to be installed.

[0114] Optionally, a manual shaft can be inserted into the first motor shaft mounting hole in the above-mentioned embodiment 1 and the second motor shaft mounting hole in the embodiment 2. The manual shaft is set as a manually toggle switch, which can also drive the one-piece extrusion component to work. Its specific working principle is the same as that of inserting the motor shaft, which will not be repeated here.

[0115] The extrusion component in Example 1 and Example 2 of the utility model adopts an integrated structure, which strengthens the structural strength of the extrusion component, simplifies the structure of the pump head structure, and is beneficial to subsequent assembly work. The integrated structure saves assembly time and improves assembly work efficiency.

[0147] The utility model also provides a peristaltic pump, including: Figure 3 or Figure 4 The pump head structure further comprises:

[0148] The deceleration component and the driving component are linearly arranged and connected in sequence.

[0149] The driving component of the utility model is preferably a driving motor, and the reduction component is preferably a reduction motor, which can be a reduction motor with a gear or planetary gear structure. The peristaltic pump of the utility model adopts the above-mentioned pump head structure, which reduces the overall volume of the peristaltic pump and ensures that the fluid flux will not be reduced. Figure 4 The pump head structure and the peristaltic pump structure can also improve fluid flux.

[0150] The following is combined with Figures 5 and 6 As shown, the peristaltic pump provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0151] Example 5

[0152] Reference Figure 5 As shown, the peristaltic pump includes: a speed reduction component 18 and a drive component 19, and the pump head structure is similar to that of the reference Figure 3 The pump head structure scheme shown is the same and will not be repeated here. The driving shaft of the driving assembly 19 in this embodiment passes through the reduction assembly 18, and passes through the first motor shaft mounting hole of the pump head structure. Along the axial direction of the driving shaft of the driving assembly 19, the pump head structure, the reduction assembly 18 and the driving assembly 19 are connected in sequence and arranged linearly.

[0153] Optionally, the drive assembly 19 is a drive component of the peristaltic pump itself, and the peristaltic pump is operated by the rotation of the drive shaft of the drive assembly 19. The drive shaft of the drive assembly 19 can realize forward and reverse rotation, and the driving force in different directions can be changed by forward and reverse rotation to realize the change of the direction of fluid flow. Forward and reverse rotation are two relative directions, which realize the change of the input and output directions of the fluid in the elastic hose in the pump head structure, and can be selected as the counterclockwise or clockwise rotation direction of the drive shaft of the drive assembly 19.

[0154] On the basis of the pump head structure, the present application adds a reduction assembly 18 and a drive assembly 19, without adding an additional drive structure, with a simple structure, reduced energy consumption, reduced use costs, time and labor saving, easy and quick replacement and disassembly, and reduced manual assembly operation time, thereby reducing labor costs and time costs.

[0155] Example 6

[0156] Reference Figure 6As shown, the peristaltic pump of this embodiment adopts Figure 4 The pump head structure shown also includes a speed reduction assembly 18 and a drive assembly 19. The difference from Example 5 is that a different pump head structure is used for connection. Figure 4 The pump head structure shown may be longer in its axial direction than Figure 3 The pump head structure shown is long in its axial direction, and accordingly, the length of the drive shaft of the drive assembly 19 is adapted to the pump head structure.
