[0048] Power output component 100, which includes a power output section;

[0049] Power receiver 200, power receiver 200 includes:

[0050] The receiving housing 201 has an installation cavity 2011 inside, and the receiving housing 201 is detachably connected to the power output component 100.

[0051] The conveying pipe 202 is fixed inside the mounting cavity 2011;

[0052] The pressurizing component 203 is rotatably connected inside the mounting cavity 2011. The conveying pipe 202 is located between the pressurizing component 203 and the inner wall of the mounting cavity 2011. The pressurizing component 203 applies pressure to the conveying pipe 202. The pressurizing component 203 is provided with a power receiving part. When the receiving housing 201 and the power output component 100 are connected together, the power output part and the power receiving part are connected.

[0053] When the peristaltic pump is in normal use, the delivery pipe 202 is connected to the water source, and the receiving housing 201 is connected to the power output component 100. At this time, the power output part and the power receiving part are connected together. The power output component 100 drives the power receiving part to rotate through the power output part, thereby driving the pressurizing component 203 to rotate. The pressurizing component 203 applies pressure to the delivery pipe 202 to deliver the liquid. When the delivery pipe 202 ages, it is only necessary to separate the receiving housing 201 from the power output component 100. At this time, the power output part and the power receiving part are also separated. Then, a new power receiving component 200 is connected to the original power output component 100. Replacement is very convenient and low-cost.

[0054] like Figures 4-8 As shown, the following is one embodiment of the pressurizing component 203, which includes:

[0055] A pressure bracket 2031 is rotatably connected to the mounting cavity 2011. A pressure ring groove 2032 is provided on the pressure bracket 2031. The power receiving part is disposed on the pressure bracket 2031.

[0056] Several pressurizing columns 2033 are rotatably connected in the pressurizing ring groove 2032, and the outer wall of the pressurizing column 2033 abuts against the conveying pipe 202.

Preferably, there are three pressure columns 2033, which are evenly distributed around the axis of the pressure support 2031.

[0058] like Figure 6 and Figure 7 As shown, the power receiving part is configured as a receiving groove 204, and the power output part is configured as an output protrusion 101, which is inserted into the receiving groove 204. When the receiving housing 201 is connected to the power output component 100, the output protrusion 101 is inserted into the receiving groove 204, so that the pressure component 203 can be rotated through the output protrusion 101 and the receiving groove 204.

[0059] like Figure 4 and Figure 5 As shown, the power output component 100 includes an output motor 102 and a speed change device 103.

The shaft of the output motor 102 passes through the gearbox inlet hole 1033 and extends into the gearbox cavity 1032.

[0062] The first drive gear 1036 is fixed on the shaft of the output motor 102;

[0063] A first connecting bracket 1037 is disposed on the side of the first drive gear 1036 away from the output motor 102. A plurality of first connecting gears 1038 are rotatably connected to the first connecting bracket 1037. The first connecting gears 1038 mesh with the first drive gear 1036 and the internal gear 1035 of the speed change, respectively. A first fixed gear 1039 is fixed on the side of the first connecting bracket 1037 facing away from the first drive gear 1036.

[0064] The second connecting bracket 1040 is disposed on the side of the first connecting bracket 1037 facing away from the first drive gear 1036. A plurality of second connecting gears 1041 are rotatably connected to the second connecting bracket 1040. The second connecting gears 1041 mesh with the first fixed gear 1039 and the internal gear 1035 of the speed change, respectively. The output protrusion 101 is fixed on the second connecting bracket 1040 and passes through the speed change outlet hole 1034.

[0065] The shaft of the output motor 102 drives the first drive gear 1036, which, through the transmission of the internal gear 1035, the first connecting gear 1038, the second connecting gear 1041, etc., ultimately drives the output protrusion 101 to rotate.

[0066] The following describes a detachable arrangement between the gear shift bracket 1031 and the receiving housing 201. The gear shift bracket 1031 has a connecting groove 1042 on the side away from the output motor 102. The inner wall of the connecting groove 1042 has a connecting protrusion 1043. The connecting protrusion 1043 has a transverse slot 1044. The transverse slot 1044 has a slot opening 1045. The outer wall of the receiving housing 201 has a locking block 205 that engages with the transverse slot 1044.

[0067] When it is necessary to connect the gear shift bracket 1031 and the receiver housing 201, first align the locking block 205 with the slot opening 1045, then rotate the gear shift bracket 1031 to insert the locking block 205 into the transverse slot 1044, thus completing the connection between the gear shift bracket 1031 and the receiver housing 201. When it is necessary to separate the gear shift bracket 1031 and the receiver housing 201, simply rotate the gear shift bracket 1031 in the opposite direction.

[0068] The output protrusion 101 has an output surface 1047, and the receiving groove 204 has a receiving surface 210. During power transmission, the output surface 1047 and the receiving surface 210 are in contact. There are several output protrusions 101, which are evenly distributed around the axis of the second connecting bracket 1040. The receiving groove 204 corresponds to each output protrusion 101.

[0069] like Figure 6 and Figure 8 The outer wall of the receiving housing 201 is provided with a positioning protrusion 206, and the connecting protrusion 1043 is provided with a positioning groove 1046 for the positioning protrusion 206 to be inserted into. When the locking block 205 is inserted into the transverse locking groove 1044, the positioning protrusion 206 and the positioning groove 1046 are inserted into each other, which plays a positioning role.

[0070] like Figure 7 As shown, the side wall of the mounting cavity 2011 is provided with a first side hole 2012 and a second side hole 2013, and the two ends of the conveying pipe 202 pass through the first side hole 2012 and the second side hole 2013 respectively.

[0071] like Figures 10-13As shown, a peristaltic pump assembly is also disclosed, including the peristaltic pump described above, and a liquid addition bottle 3. The receiving housing 201 has an upward-facing bottle groove 207, and the inner wall of the bottle groove 207 has an internally threaded hole 208. The bottle mouth of the liquid addition bottle 3 is threadedly connected to the internally threaded hole 208. The bottom of the bottle groove 207 has a liquid inlet 209, which is connected to the inlet of the delivery pipe 202 via a pipeline. Thus, the liquid addition from the liquid addition bottle 3 flows through the liquid inlet 209 to the inlet of the delivery pipe 202, and is then delivered by the peristaltic pump. This integrates the peristaltic pump power receiver 200 and the liquid addition bottle 3, allowing for simultaneous replacement of the peristaltic pump power receiver 200 when replacing the liquid addition bottle 3.
