The pump head housing includes an upper housing, a middle housing, and a lower housing. The drive assembly includes a drive motor, a motor housing, and a motor rear cover mounted on the side of the motor housing facing away from the pump head housing. The mounting bracket is locked to the motor housing with screws.

[0004] In view of the aforementioned technologies, the inventors believe there is a need to provide an RO pump with an alternative mounting structure. Utility Model Content

[0005] This application provides a six-chamber RO pump, wherein the mounting base of the six-chamber RO pump is relatively easy to install during the assembly process.

[0006] The six-chamber RO pump provided in this application adopts the following technical solution:

[0007] A six-chamber RO pump includes a pump head housing, a compression assembly installed inside the pump head housing, a drive assembly for driving the compression assembly, and a mounting base for mounting the RO pump. The pump head housing includes an upper housing, a middle housing, and a lower housing. The drive assembly includes a drive motor, a motor housing, and a motor rear cover installed on the side of the motor housing facing away from the pump head housing. The lower housing has a first extension that conforms to the motor housing, and the motor rear cover has a second extension that conforms to the motor housing and corresponds to the first extension. The bottom end of the first extension has a first arrangement groove, and a first locking assembly is disposed within the first arrangement groove. The bottom end of the second extension has a second arrangement groove, and a second locking assembly is disposed within the second arrangement groove. The mounting base has a supporting arc surface that conforms to the motor housing. The mounting base has a first locking groove at its top end that cooperates with the first locking assembly and a second locking groove at its bottom end that cooperates with the second locking assembly.

[0008] By adopting the above technical solution, a locking component is provided in the first extension, a second locking component is provided in the second extension, and a first locking groove that cooperates with the first locking component is opened on the top of the mounting base, and a second locking groove that cooperates with the second locking component is opened on the bottom of the mounting base. When the mounting base is installed between the first extension and the second extension, the first locking component of the first extension will be inserted into the first locking groove on the top of the mounting base, and the second locking component of the second extension will be inserted into the second locking groove on the top of the mounting base, which helps to improve the ease of installation between the mounting base and the RO pump.

[0009] Optionally, the first locking component includes a first latch and a first spring, one end of the first spring abutting the bottom end of the first arrangement groove and the other end abutting the first latch; the second locking component includes a second latch and a second spring, one end of the second spring abutting the bottom end of the second arrangement groove and the other end abutting the second latch.

[0010] By adopting the above technical solution, the specific structure of the locking component is disclosed. When the mounting base is inserted, the top front end of the mounting base abuts against the first locking tongue, causing the bottom front end of the mounting base to abut against the second locking tongue. When the mounting base is further inserted, the first spring at the bottom of the first locking tongue and the second spring at the bottom of the second locking tongue are compressed under pressure. When the first arrangement slot and the first locking slot, the second arrangement slot and the second locking slot are aligned, the first spring and the second spring return to their original state, thereby achieving the engagement of the first locking component with the first locking slot, the second locking component and the second locking slot.

[0011] Optionally, the outer end of the first latch is provided with a first guide surface on the side facing away from the motor housing; the outer end of the second latch is provided with a second guide surface symmetrically arranged with the first guide surface on the side facing away from the motor housing.

[0012] By adopting the above technical solution, guide surfaces are provided at the outer ends of the first and second locking tongues, making it easier to slide when inserting the mounting slot.

[0014] By adopting the above technical solution, an arc-shaped plate structure for the first and second locking tongues is disclosed. The arc-shaped plate structure increases the contact area between the first locking tongue and the first arrangement groove, the second locking tongue and the second arrangement groove, the first locking tongue and the first locking groove, and the second locking tongue and the second locking groove, resulting in higher structural strength and making the mounting base less likely to come off.

[0015] Optionally, the bottom side of the first extension is provided with a first protruding ridge arranged along the insertion direction of the mounting base; the top side of the second extension is provided with a second protruding ridge arranged along the insertion direction of the mounting base; the mounting base has a first groove for arranging the first protruding ridge and a second groove for arranging the second protruding ridge.

[0016] By adopting the above technical solution, the first and second protruding ridges guide the insertion of the mounting base, enabling the mounting base to be inserted in a straight line, thereby improving the sliding stability of the mounting base.

[0017] Optionally, the number of the first protrusions is two and they are arranged symmetrically from left to right; the number of the second protrusions is two and they are arranged symmetrically from left to right.

[0018] By adopting the above technical solution, two first protruding ridges are provided on the bottom side of the first extension, and two second protruding ridges corresponding to the first protruding ridges are provided on the top of the second extension, which helps to further improve the sliding stability of the mounting base.

[0019] Optionally, the bottom of the mounting base has four support legs with shock-absorbing pads, and the support legs are symmetrically arranged in pairs on both sides of the bottom of the mounting base.

[0020] By adopting the above technical solution, four support legs are set at the bottom of the mounting base, and shock-absorbing pads are arranged on the support legs, which helps to improve the connection stability between the mounting base and the inner wall of the water purifier.

[0021] Optionally, the compression assembly includes a diaphragm and a compression support, with six drive chambers formed between the diaphragm and the compression support.

[0022] By adopting the above technical solution, six drive chambers are set between the compression support and the diaphragm, which helps to improve the flow stability of the RO pump, thereby achieving continuous delivery of liquid.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By providing a locking component in the first extension and a second locking component in the second extension, and by opening a first locking groove on the top of the mounting base to cooperate with the first locking component and opening a second locking groove on the bottom of the mounting base to cooperate with the second locking component, when the mounting base is installed between the first extension and the second extension, the first locking component will be inserted into the first locking groove and the second locking component will be inserted into the second locking groove, thereby realizing the plug-in installation between the mounting base and the RO pump;

[0025] 2. By providing guide surfaces at the outer ends of the first and second locking tongues, the smoothness of the mounting bracket insertion installation is improved;

[0026] 3. By providing a first protruding ridge in the first extension, a second protruding ridge in the second extension, and a first sliding groove for arranging the first protruding ridge and a second sliding groove for arranging the second protruding ridge in the mounting base, the insertion of the mounting base is guided, thereby realizing the linear sliding installation of the mounting base.
