Technical Field

[0002] In the related technology, a piston pump can be used to realize the flushing function. The piston pump mainly uses a motor to drive a gear with an eccentric structure to rotate. The piston and the gear are connected by a connecting rod.

DETAILED DESCRIPTION

[0050] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0051] There is a pump body structure 1 in the related art. Figure 1 is a cross-sectional diagram of a pump structure in a related art tooth washer. Figure 2 is an example diagram of the pump structure in the related art tooth washer, wherein: Figure 1 yes Figure 2 A cross-sectional diagram of Figure 1 and Figure 2 As shown, the motor is connected to the gear, the piston is located inside the pump body, the piston and the gear are connected by a connecting rod, and a water inlet and a water outlet are provided on the pump body, wherein the water inlet is connected to the water inlet pipe, the water inlet pipe can be connected to the water tank, and the water outlet is connected to the nozzle. After the motor is started, it will drive the gear connected to the motor to rotate. When the gear rotates, it will push the piston in the pump body to reciprocate through the connecting rod. When the gear pushes the piston to move in the direction of the gear through the connecting rod, the volume of the pump body will increase, forming a negative pressure, thereby sucking water from the water tank from the water inlet through the water inlet channel; when the gear pushes the piston to move in the direction of the water outlet through the connecting rod, the volume of the pump body will decrease, thereby compressing the water in the pump body and spraying it out from the nozzle through the water outlet.

[0052] The above scheme uses the reciprocating motion of the piston to change the volume in the pump body, so that water flows from the water tank into the pump body through the water inlet pipe, or compresses the liquid in the pump body and sprays it out from the nozzle through the water outlet. However, since the gear is connected to the motor and the piston is connected to the gear through a connecting rod, when moving, the motor needs to drive the gear to rotate, and the gear rotation drives the connecting rod to move, and the connecting rod then drives the piston to reciprocate. The steps are relatively cumbersome, and there are many transmission structures and the stability of manufacturing precision is low. In addition, with the increase of usage time, the joints of the various components are prone to wear, which generates loud noise during operation, and the piston is prone to leakage or no water discharge after wear, which in turn causes the entire water flosser to fail.

[0053] In this regard, the present disclosure provides a pump structure. Figure 3 is an exemplary diagram of a pump structure according to an exemplary embodiment. Figure 3 As shown, the pump body structure 1 includes:

[0054] The pump cover 100 is provided with a water inlet channel 101 and a water outlet channel 102;

[0055] The driving assembly 200 includes a driving shaft 201;

[0056] The pump body 300 includes an elastic water storage chamber 301 and a first bracket 302; the elastic water storage chamber 301 is located between the pump cover 100 and the first bracket 302, one end of the first bracket 302 is connected to the elastic water storage chamber 301, and the other end is connected to the drive shaft 201, and the first bracket 302 is inclined relative to the drive shaft 201;

[0057] The driving assembly 200 is used to drive the first bracket 302 to drive the elastic water storage chamber 301 to rotate obliquely around the driving shaft 201. The elastic water storage chamber 301 undergoes a first elastic deformation during the rotation to introduce water through the water inlet channel 101, or undergoes a second elastic deformation during the rotation to discharge the water in the elastic water storage chamber 301 through the water outlet channel 102; wherein, the volume of the elastic water storage chamber 301 increases when the first elastic deformation occurs, and the volume of the elastic water storage chamber 301 decreases when the second elastic deformation occurs.

[0058] The pump body structure 1 in the embodiment of the present disclosure can be used in smart home devices, such as water flossers, dental washer, dishwasher, washing machine, smart fish tank, water heater and other devices.

[0059] In the embodiment of the present disclosure, a water inlet channel 101 and a water outlet channel 102 are provided on the pump cover 100, wherein Figure 3As shown, the water outlet channel 101 is arranged on the side of the pump cover 100 away from the pump body 300, and the water inlet channel 102 is arranged on the side of the pump cover 100. It should be noted that the water outlet channel 101 can also be arranged on the side of the pump cover 100, and the water inlet channel 102 can also be arranged on the side of the pump cover 100 away from the pump body 300. This is not limited to the embodiments of the present disclosure.

[0060] In the embodiment of the present disclosure, the drive assembly 200 includes a drive shaft 201, and the drive assembly 200 may also include a drive assembly body, which may be a motor, an electric motor, or other components that can convert electrical energy into mechanical energy, and may specifically be a DC motor, an AC motor, a stepper motor, a high-speed motor, a vibration motor, a pulse motor, etc. The drive shaft 201 may be a rotating drive shaft, and the drive shaft 201 is connected to the body of the drive assembly 200. For example, the drive shaft 201 may be connected to the center of the body of the drive assembly 200.

[0061] In the embodiments of the present disclosure, the drive shaft 201 can be adhered to the body of the drive component 200, or can be connected to the body of the drive component 200 by a direct connection method, or can be connected to the body of the drive component 200 by a connecting module such as a flange or a coupling, or can be embedded in the body of the drive component 200, and the embodiments of the present disclosure do not impose any restrictions on this.

[0062] In the disclosed embodiment, the pump body 300 includes an elastic water storage chamber 301 and a first bracket 302. The elastic water storage chamber 301 is made of elastic materials such as rubber, silicone, polyurethane (PU), thermoplastic elastomer (TPE), polymer materials, etc. It should be noted that the elastic water storage chamber 301 can be one or more.

[0063] In the embodiment of the present disclosure, the elastic water storage chamber 301 is located between the pump cover 100 and the first bracket 302, and one end of the first bracket 302 is connected to the elastic water storage chamber 301, wherein the elastic water storage chamber 301 can be adhered to the side of the first bracket 302 facing the pump cover 100 by an adhesive, and the elastic water storage chamber 301 and the first bracket 302 can also be connected by bolt connection, welding connection, clamp connection, elastic connection and other connection methods, and the embodiment of the present disclosure does not limit this.

[0064] In the disclosed embodiment, the other end of the first bracket 302 is connected to the drive shaft 201, and the first bracket 302 is tilted relative to the drive shaft 201. The first bracket 302 can be connected to the drive shaft 201 by adhesive connection, bolt connection, welding connection, clamp connection, elastic connection, etc. It should be noted that the first bracket 302 is tilted relative to the drive shaft 201, which means that the angle formed between the first bracket 302 and the drive shaft 201 is not a right angle or a flat angle.

[0065] In the disclosed embodiment, the driving component 200 is used to drive the first bracket 302 to drive the elastic water storage chamber 301 to rotate obliquely around the driving shaft 201. After the driving component 200 is started, the driving shaft 201 rotates. Since one end of the first bracket 302 is connected to the driving shaft 201 and the first bracket 302 is tilted relative to the driving shaft 201, the driving shaft 201 will drive the first bracket 302 to rotate obliquely around the driving shaft 201. Since the other end of the first bracket 302 is connected to the elastic water storage chamber 301, the oblique rotation of the first bracket 302 around the driving shaft 201 will drive the elastic water storage chamber 301 to rotate obliquely around the driving shaft 201.

[0066] In the embodiment of the present disclosure, the elastic water storage chamber 301 undergoes a first elastic deformation during rotation to introduce water through the water inlet channel 101, or undergoes a second elastic deformation during rotation to discharge the water in the elastic water storage chamber 301 through the water outlet channel 102, wherein the volume of the elastic water storage chamber 301 increases when the first elastic deformation occurs, and the volume of the elastic water storage chamber 301 decreases when the second elastic deformation occurs.

[0067] It should be noted that in the embodiment of the present disclosure, since the elastic water storage chamber 301 is located between the pump cover 100 and the first bracket 302, and the elastic water storage chamber 301 rotates in an inclined manner around the drive shaft 201 along with the first bracket 302, the elastic water storage chamber 301 will undergo elastic deformation during the rotation process. Specifically, when the elastic water storage chamber 301 rotates from a position away from the pump cover 100 to a position close to the pump cover 100, the elastic water storage chamber 301 is squeezed by the first bracket 302 and the pump cover 100, and the volume will become smaller. At this time, the elastic water storage chamber 301 undergoes a second elastic deformation, that is, the state of the elastic water storage chamber 301 is compressed. Due to the squeezing, the elastic water storage chamber 301 will push the water in the elastic water storage chamber 301 outward. Push, therefore, when the elastic water storage chamber 301 undergoes the second elastic deformation, the water in the elastic water storage chamber 301 can be discharged through the water outlet channel 102; when the elastic water storage chamber 301 rotates from a position close to the pump cover 100 to a position away from the pump cover 100, the elastic water storage chamber 301 changes from a squeezed state by the first bracket 302 and the pump cover to a non-squeezed state, and the volume will increase. At this time, the elastic water storage chamber 301 undergoes the first elastic deformation, that is, the state of the elastic water storage chamber 301 is compressed and then expanded. At this time, due to the increase in the volume of the elastic water storage chamber 301, negative pressure will be generated in the chamber, thereby generating suction. Therefore, when the elastic water storage chamber 301 undergoes the first elastic deformation, the water in the elastic water storage chamber 301 can be discharged through the water outlet channel 102.

[0068] In the embodiment of the present disclosure, the elastic water storage chamber 301 undergoes a first elastic deformation during the rotation process to introduce water through the water inlet channel 101, and the elastic water storage chamber 301 undergoes a second elastic deformation during the rotation process to discharge the water in the elastic water storage chamber 301 through the water outlet channel 102; in some embodiments, a first switch component such as a valve may be included between the elastic water storage chamber 301 and the water inlet channel 101, and when the elastic water storage chamber 301 undergoes the first elastic deformation, the first switch component is turned on, so that the elastic water storage chamber 301 introduces water through the water inlet channel 101, and specifically, the first switch component may be a one-way valve, a stop valve, a ball valve, a butterfly valve, etc. It should be noted that the first control component may not be provided between the elastic water storage chamber 301 and the water inlet channel 101, and the embodiment of the present disclosure does not limit this.

[0069] In other embodiments, a second switch component such as a valve may be included between the elastic water storage chamber 301 and the water outlet channel 102. When the elastic water storage chamber 301 undergoes a second elastic deformation, the second switch component is turned on, so that the water in the elastic water storage chamber 301 can be discharged through the water outlet channel 102. Specifically, the second switch component may be a one-way valve, a stop valve, a ball valve, a butterfly valve, etc. It should be noted that the second switch component may not be provided between the elastic water storage chamber 301 and the water outlet channel 102, and only the aforementioned first switch component may be provided, or only the second switch component may be provided, or the first switch component and the second switch component may be provided at the same time, and the embodiments of the present disclosure do not limit this.

[0070] In other embodiments, the elastic water storage chamber 301, the water inlet channel 101 and the water outlet channel 102 may also be connected via a third switch component. When the elastic water storage chamber 301 undergoes a first elastic deformation, the third switch component connects the water inlet channel 101 and the elastic water storage chamber 301, so that water is introduced into the elastic water storage chamber 301 through the water inlet channel 101. When the elastic water storage chamber 301 undergoes a second elastic deformation, the third control component connects the water outlet channel 102 and the elastic water storage chamber 301 while shutting off the water inlet channel 101 and the elastic water storage chamber 301, so that the water in the elastic water storage chamber 301 is discharged through the water outlet channel 102, and the water is not discharged into the water inlet channel. For example, the third switch component can be a U-shaped valve, a Y-shaped valve, etc. For example, the third switch component is a U-shaped valve, one end of the U-shaped valve opening is connected to the water inlet channel 101, and the other end is connected to the water outlet channel 102. The bottom of the U-shaped valve is connected to the elastic water storage chamber 301. When the elastic water storage chamber 301 undergoes a first elastic deformation, the elastic water storage chamber 301 introduces water through the water inlet channel 101 and the valve port of the U-shaped valve connected to the water inlet channel 101. When the elastic water storage chamber 301 undergoes a second elastic deformation, the water in the elastic water storage chamber 301 is discharged through the water outlet channel 102 and the valve port of the U-shaped valve connected to the water outlet channel 102. It should be noted that the third control component may not be provided between the elastic water storage chamber 301, the water inlet channel 101 and the water outlet channel 102, and the embodiments of the present disclosure are not limited to this.

[0071] It should be noted that, in the embodiments of the present disclosure, as mentioned above, the elastic water storage chamber 301 may be one or more; in some embodiments, there is one elastic water storage chamber 301, and illustratively, the elastic water storage chamber 301 may be located at the center position of the first bracket 302 facing the pump cover 302, and when the elastic water storage chamber 301 undergoes a first elastic deformation and the elastic water storage chamber 301 rotates to the position connected to the water inlet channel 101, the elastic water storage chamber 301 introduces water through the water inlet channel 101; when the elastic water storage chamber 301 undergoes a second elastic deformation and the elastic water storage chamber 301 rotates to the position connected to the water outlet channel 102, the water in the elastic water storage chamber 301 is discharged through the water outlet channel 102.

[0072] In other embodiments, there are multiple elastic water storage chambers 301, and the multiple elastic water storage chambers 301 are distributed on the side of the first bracket 302 away from the driving assembly 200; at least two of the elastic water storage chambers 301 undergo different elastic deformations.

[0073] In the disclosed embodiment, there are multiple elastic water storage chambers 301, such as 2, 3, 5, etc. For example, when there are multiple elastic water storage chambers 301, the multiple elastic water storage chambers 301 can be evenly spaced and arranged on the side of the first bracket 302 away from the driving assembly 200.

[0075] In the embodiment of the present disclosure, two elastic water storage chambers 301 are used for illustration. When one of the elastic water storage chambers 301 undergoes the first elastic deformation and rotates to connect to the water inlet channel 101, the elastic water storage chamber 301 introduces water through the water inlet channel 101.

[0077] The pump body structure 1 provided in the embodiment of the present disclosure drives the first bracket 302 to rotate obliquely around the drive shaft 201 through the rotation of the drive shaft 201, thereby causing the elastic water storage chamber 301 connected to the first bracket 302 to also rotate obliquely around the drive shaft 201, so that the elastic water storage chamber 301 undergoes elastic deformation, changes the volume of the elastic water storage chamber 301, and then absorbs or discharges water. The arrangement of the pump lifting structure in the embodiment of the present disclosure, on the one hand, does not require the use of a gear and piston structure, has fewer transmission structures, simpler manufacturing processes, and higher stability in manufacturing precision; on the other hand, the elastic water storage chamber 301 in the embodiment of the present disclosure has higher wear resistance, which can reduce the problems of water leakage and water failure caused by piston wear in the prior art, and because the elastic material of the elastic water storage chamber 301 can reduce the noise generated by the pump body during movement.

[0099] In the disclosed embodiment, the valve 402 b of the second one-way valve 402 moves away from the second groove 104 c when the elastic water storage chamber 301 undergoes the second elastic deformation so that the water in the elastic water storage chamber 301 passes through the second through hole 104 d and then is discharged through the water outlet channel 102 .

[0100] It should be noted that the first one-way valve 401 may include multiple ones, such as each elastic water storage chamber 301 corresponds to one first one-way valve 401, or each elastic water storage chamber 301 corresponds to multiple first one-way valves 401; the second one-way valve 402 may also be one or more, such as each elastic water storage chamber 301 corresponds to one second one-way valve 402, or each elastic water storage chamber 301 corresponds to multiple second one-way valves 402, or multiple elastic water storage chambers 301 correspond to one second one-way valve 402.

By way of example, each elastic water storage chamber 301 may correspond to one first one-way valve 401, and all elastic water storage chambers 301 may correspond to one second one-way valve 402.

[0101] In the embodiment of the present disclosure, by setting the first one-way valve 401 and the second one-way valve 402, the water inlet or outlet of the elastic water storage chamber 301 can be controlled based on the switching of the one-way valve, which is more intelligent.

[0102] In some embodiments, the valve stem 401a of the first one-way valve 401 includes a first elastic member 401a1, and the valve 401b of the first one-way valve 401 includes a first valve flap 401b1, one end of the first elastic member 401a1 is fixed to the first groove 104a, and the other end of the first elastic member 401a1 is connected to the first valve flap 401b1, and the first valve flap 401b1 is opposite to the cavity opening of the elastic water storage cavity 301.

[0103] In the disclosed embodiment, the valve stem 401a of the first one-way valve 401 includes a first elastic member 401a1. Specifically, the valve stem 401a of the first one-way valve 401 may be made of elastic material, such as a spring, a bellows, an expansion joint, etc. It should be noted that the valve stem 401a of the first one-way valve 401 may be made entirely of elastic material, or elastic material may be used only in a portion of the valve stem 401a of the first one-way valve 401. The valve 401b of the first one-way valve 401 includes a first valve flap 401b1, which indicates that the valve 401b of the first one-way valve 401 is circular or petal-shaped.

[0104] In the disclosed embodiment, one end of the first elastic member 401a1 is fixed to the first groove 104a, wherein the first elastic member 401a1 can be fixed to the first groove 104a by means of screw fixing, snap fixing, limiting hole fixing, etc., and the other end of the first elastic member 401a1 is connected to the first valve flap 401b1, and the first valve flap 401b1 is opposite to the cavity opening of the elastic water storage cavity 301.

[0105] In the embodiment of the present disclosure, the valve stem 401a of the first one-way valve 401 includes a first elastic member 401a1, and the valve 401b of the first one-way valve 401 includes a first valve flap 401b1. When the elastic water storage chamber 301 undergoes a first elastic deformation, the valve stem 401a of the first one-way valve 401 is extended by the first elastic member 401a1, so that water flows into the elastic water storage chamber 301 through the first through hole 104b of the first groove 104. The process is simple and the method is convenient.

[0106] In some embodiments, the size of the first valve flap 401b1 is smaller than the size of the opening of the elastic water storage chamber 301, and the first valve flap 401b1 covers the first through hole 104b of the first groove 104a when the first elastic member 401a1 is not deformed.

[0107] In the embodiment of the present disclosure, since the first valve flap 401b1 needs to move toward the elastic water storage chamber 301 when the elastic water storage chamber 301 undergoes the first elastic deformation so that water can be introduced into the elastic water storage chamber 301 through the first through hole 104b after passing through the water inlet channel 101, the size of the first valve flap 401b1 is set to be smaller than the size of the cavity opening of the elastic water storage chamber 301, so that when the elastic water storage chamber 301 undergoes the first elastic deformation, the first valve flap 401b1 can move into the elastic water storage chamber 301 so that water can be introduced into the elastic water storage chamber 301 through the first through hole 104b after passing through the water inlet channel 101, so that water can directly flow into the elastic water storage chamber 301 through the first through hole 104b, thereby reducing the time for the elastic water storage chamber 301 to enter the water.

[0108] In the disclosed embodiment, since the first elastic member 401a1 is deformed when the elastic water storage chamber 301 undergoes the first elastic deformation, water is introduced into the elastic water storage chamber 301 through the first through hole 104b after passing through the water inlet channel 101. Therefore, the first valve flap 401b1 covers the first through hole 104b of the first groove 104a when the first elastic member 401a1 is not deformed, so that when the elastic water storage chamber 301 does not undergo the first elastic deformation, that is, when water does not enter the elastic water storage chamber 301, water cannot flow out through the first through hole 104b, thereby reducing the impact and corrosion of water on other components, thereby extending the service life of the entire machine.

[0109] In some embodiments, the valve stem 402a of the second one-way valve 402 includes a second elastic member 402a1, and the valve 402b of the second one-way valve 402 includes a second valve flap 402b1. One end of the second elastic member 402a1 is fixed to the cavity mouth surface of the elastic water storage cavity 301, and the other end of the second elastic member 402a1 is connected to the second valve flap 402b1. When the second elastic member 402a1 is not deformed, the second valve flap 402b1 is located in the second groove 104c.

[0110] In the disclosed embodiment, the valve stem 402a of the second one-way valve 402 includes a second elastic member 402a1. Specifically, the valve stem 402a of the second one-way valve 402 may be made of an elastic material, such as a spring, a bellows, an expansion joint, etc. It should be noted that the valve stem 402a of the second one-way valve 402 may be made entirely of elastic material, or elastic material may be used only in a portion of the valve stem 402a of the second one-way valve 402. The valve 402b of the second one-way valve 402 includes a second valve flap 402b1, which indicates that the valve 402b of the second one-way valve 402 is circular or petal-shaped.

[0111] In the embodiment of the present disclosure, one end of the second elastic member 402a1 is fixed to the cavity mouth surface of the elastic water storage chamber 301, wherein it can be fixed to the cavity mouth surface of the elastic water storage chamber 301 by screw fixing, snap fixing, limiting hole fixing, etc. The other end of the second elastic member 402a1 is connected to the second valve flap 402b1, and when the second elastic member 402a1 is not deformed, the second valve flap 402b1 is located in the second groove 104c.

[0112] In the embodiment of the present disclosure, the valve stem 402a of the second one-way valve 402 includes a second elastic member 402a1, and the valve 402b of the second one-way valve 402 includes a second valve flap 402b1. When the elastic water storage chamber 301 undergoes a second elastic deformation, the valve stem 402a of the second one-way valve 402 is extended by the second elastic member 402a1, so that the water in the elastic water storage chamber 301 passes through the second through hole 104d and is discharged through the water outlet channel 102. The process is simple and the method is convenient.

[0113] In some embodiments, the size of the second valve flap 402b1 is smaller than the size of the second groove 104c, and the second valve flap 402b1 covers the second through hole 104d of the second groove 104c when the second elastic member 402a1 is not deformed.

[0114] In the embodiment of the present disclosure, when the elastic water storage chamber 301 undergoes the second elastic deformation, the second valve flap 402b1 needs to move in a direction away from the second groove 104c so that the water in the elastic water storage chamber 301 passes through the second through hole 104d and is discharged through the water outlet channel 102. Therefore, the size of the second valve flap 402b1 is set to be smaller than the size of the second groove 104c. This enables the second valve flap 402b1 to move into the water outlet channel 102 when the elastic water storage chamber 301 undergoes the second elastic deformation so that the water in the elastic water storage chamber 301 passes through the second through hole 104d and is discharged through the water outlet channel 102. This enables the water to directly flow into the water outlet channel 102 through the second through hole 104d, thereby reducing the time it takes for the elastic water storage chamber 301 to discharge water.

[0115] In the embodiment of the present disclosure, since the second elastic member 402a1 is deformed when the elastic water storage chamber 301 undergoes the second elastic deformation, the water in the elastic water storage chamber 301 passes through the second through hole 104d and then is discharged through the water outlet channel 102. Therefore, the second valve flap 402b1 covers the second through hole 104d of the second groove 104c when the second elastic member 402a1 is not deformed, so that when the elastic water storage chamber 301 does not undergo the second elastic deformation, that is, when the elastic water storage chamber 301 does not discharge water, water cannot flow out through the second through hole 104d, thereby reducing the impact and corrosion of water on other components, thereby extending the service life of the entire machine.

[0116] Figures 9 and 10 is a structural example diagram of the first cover body; wherein, Fig. 9 This is a structural example of a first cover according to an exemplary embodiment. Figure 1 ; Fig.10 This is a structural example of a first cover according to an exemplary embodiment. Figure 2 For the convenience of subsequent description, the following is based on Figure 3 , Fig. 9 , Fig.10 The first cover is described in detail. Figure 3 , Fig. 9 , Fig.10 The structures with the same mark in the above-mentioned figures have the same functions.

[0117] In some embodiments, the first cover body 103 includes a first body 103a and a second body 103b, the second body 103b is sleeved in the first body 103a, the second body 103b forms a first accommodating cavity, and a second accommodating cavity is formed between the first body 103a and the second body 103b; the second groove 104c is located in the first accommodating cavity; the first groove 104a is located in the second accommodating cavity.

[0118] In the embodiment of the present disclosure, the first cover body 103 includes a first body 103a and a second body 103b. The second body 103b is sleeved in the first body 103a. The second body 103b forms a first accommodating cavity. The second groove 104c is located in the first accommodating cavity. The first accommodating cavity may also include a water outlet channel 102. A second accommodating cavity is formed between the first body 103a and the second body 103b. The first groove 104a is located in the second accommodating cavity.

[0119] In the disclosed embodiment, when the elastic water storage chamber 301 undergoes the first elastic deformation, water is introduced into the elastic water storage chamber 301 through the first through hole 104b in the first groove 104a after passing through the water inlet channel 101; when the elastic water storage chamber 301 undergoes the second elastic deformation, the water in the elastic water storage chamber 301 is discharged through the water outlet channel 102 after passing through the second through hole 104d in the second groove 104c. Therefore, locating the first groove 104a in the second accommodating chamber and locating the second groove 104c in the first accommodating chamber can isolate the water inlet channel and the water outlet channel, which is more intelligent.

[0120] In the disclosed embodiment, the depth of the second accommodating chamber may be greater than a preset depth threshold, wherein the preset depth threshold is a preset value. Setting the depth of the second accommodating chamber to be greater than the preset depth threshold can store water in the second accommodating chamber through the water inlet channel 101, so that when the elastic water storage chamber 301 undergoes a first deformation, the water in the second accommodating chamber can first flow into the elastic water storage chamber 301, thereby increasing the water inlet efficiency of the elastic water storage chamber 301.

[0121] In some embodiments, the second accommodating cavity includes a plurality of first grooves 104 a , and the plurality of first grooves 104 a surround the first accommodating cavity.

[0122] In the embodiment of the present disclosure, since the elastic water storage chamber 301 rotates obliquely around the driving shaft 201 and the first through hole 104b is located in the first groove 104a, when the elastic water storage chamber 301 undergoes the first elastic deformation, water flows into the elastic water storage chamber 301 through the first through hole 104b of the first groove 104. Therefore, a plurality of first grooves 104a are arranged in the second accommodating chamber, and the plurality of first grooves 104a surround the first accommodating chamber, thereby achieving uniform water inlet, reducing the problem of excessive or insufficient local pressure caused by a single water inlet point, and at the same time improving the water inlet efficiency.

[0129] In the embodiment of the present disclosure, the elastic water storage chamber 301 is fixed to the first bracket body 302a through the third through hole 302c. The elastic water storage chamber 301 can be fixed to the first bracket body 302a through the third through hole 302c by bolts or screws. Specifically, the third through hole 302c is designed with an internal thread, and the elastic water storage chamber 301 is equipped with matching bolts or screws. The position where the bolts or screws are provided in the elastic water storage chamber 301 is passed through the third through hole 302c, and is tightened on the side of the first bracket body 302 facing the driving assembly 200 to achieve the fixation of the elastic water storage chamber 301 to the first bracket body 302a; in addition, the elastic water storage chamber 301 can also be fixed to the first bracket body 302a through the third through hole 302c by a snap fixation method, a clamp fixation method, a welding fixation method, an adhesive fixation method, etc., and the embodiment of the present disclosure does not limit this.

[0130] In the embodiment of the present disclosure, by setting the third through hole 302c on the first bracket body 302a, the elastic water storage chamber 301 is fixed to the first bracket body 302a through the third through hole 302c, which can improve the stability of the fixation between the elastic water storage chamber 301 and the first bracket body 302a.

[0131] In the embodiment of the present disclosure, the bracket shaft 302b is fixed to the driving shaft 201 and is tilted relative to the driving shaft 201. In some embodiments, the bracket shaft 302b may be fixed to the driving shaft 201 by an adhesive.

[0132] In some other embodiments, the pump body structure 1 includes a coupling 303, and the support shaft 302b and the drive shaft 201 are fixed to the coupling 303 respectively.

[0133] In the embodiments of the present disclosure, the coupling can be a flexible coupling, a rigid coupling, a block coupling, a diaphragm coupling, a universal joint, an elastic pin, a flange slider, a drum-shaped tooth, a plum blossom-shaped, a serpentine spring, an elastic sleeve, an expansion sleeve, etc., and the embodiments of the present disclosure are not limited to this. The embodiments of the present disclosure take the block coupling as an example for explanation. The block coupling may include two accommodating chambers for placing the bracket shaft 302b and the drive shaft 201.

[0134] In the embodiment of the present disclosure, the bracket shaft 302b and the driving shaft 201 are fixed by the coupling 303, so that the bracket shaft 302b and the driving shaft 201 can be protected and the stability of the tilting rotation of the bracket shaft 302b around the driving shaft 201 can be improved.

[0135] In some embodiments, the first bracket body 302a includes a support surface with a central protrusion, and the elastic water storage cavity 301 is away from the central protrusion of the support surface.

[0136] In the embodiment of the present disclosure, the first bracket body 302a includes a supporting surface with a middle protrusion, that is, the first bracket body 302a is a structure with a middle protrusion and smooth or concave surroundings. The height of the supporting surface with a middle protrusion of the first bracket body 302a can be greater than a preset height threshold, wherein the preset height threshold is a set value and can be changed according to the size of the elastic water storage chamber 301.

[0137] In the disclosed embodiment, a first bracket body 302a is provided with a support surface including a middle protrusion, and the elastic water storage chamber 301 is away from the middle protrusion of the support surface. On the one hand, the middle protrusion of the support surface can more effectively disperse and bear the weight and pressure from the elastic water storage chamber 301 or other connecting parts, thereby improving the stability of the overall structure; on the other hand, it can optimize the spatial layout, that is, it can increase the size of the elastic water storage chamber 301 to a certain extent to increase the water storage volume of the elastic water storage chamber 301.

[0138] Fig.12 is a cross-sectional diagram of a pump structure according to an exemplary embodiment. Fig.12As shown, the support shaft 302b of the first support 302 is connected to the drive shaft 201 of the drive assembly 200 through a coupling 303, and the first support body 302a is connected to the support shaft 302b. It should be noted that the support shaft 302b is inclined with the drive shaft 201 in the coupling 303, and the elastic water storage chamber 301 is fixed on the first support body 302a. When the driving assembly 200 is started, it will drive the driving shaft 201 to rotate, and the driving shaft 201 will drive the bracket shaft 302b to rotate obliquely around the driving shaft 201 through the coupling 303. Since the first bracket body 302a is connected to the bracket shaft 302b, the elastic water storage chamber 301 is fixed on the first bracket body 302a. Therefore, the elastic water storage chamber 301 will rotate obliquely around the driving shaft 201 along with the first bracket body 302a. During the rotation process, due to the setting position, material and rotation method of the elastic water storage chamber 301, the elastic water storage chamber 301 will undergo elastic deformation. When the elastic water storage chamber 301 undergoes the first elastic deformation, the volume of the elastic water storage chamber 301 increases, thereby generating suction. At this time, since the valve stem 401a of the first one-way valve 401 includes the first elastic member 401a1, the first elastic member 401a1 will rotate along with the elastic water storage chamber 301 undergoes a first elastic deformation and stretches, thereby causing the valve (valve flap) 401b (401b1) of the first one-way valve 401 to move into the elastic water storage chamber 301, so that water flows into the elastic water storage chamber 301 through the water inlet channel 101; when the elastic water storage chamber 301 undergoes a second elastic deformation, the volume of the elastic water storage chamber 301 decreases, thereby pushing the water stored in the elastic water storage chamber 301 outward from the elastic water storage chamber 301. At this time, since the valve stem 402a of the second one-way valve 402 includes a second elastic member 402a1, the second elastic member 402a1 will stretch as the elastic water storage chamber 301 undergoes a second elastic deformation, thereby causing the valve (valve flap) 402b (402b1) of the second one-way valve 402 to move away from the elastic water storage chamber 301, so that the water in the elastic water storage chamber 301 flows out through the water outlet channel 102.

[0139] Fig.13 FIG. 1 is an example diagram of the appearance of a water flosser according to an exemplary embodiment. Fig.13 As shown, the water flosser includes the aforementioned pump structure 11, a water tank 501 and a nozzle 502;

[0140] The water tank 501 is connected to the water inlet channel 101, and the elastic water storage cavity 301 allows the water in the water tank 501 to be introduced through the water inlet channel 101 when the first elastic deformation occurs;

[0141] The nozzle 502 is connected to the water outlet channel 102 , and when the elastic water storage chamber 301 undergoes the second elastic deformation, the water in the elastic water storage chamber 301 is sprayed out through the nozzle 502 via the water outlet channel 102 .

[0142] In the embodiment of the present disclosure, the description of the pump structure 1 can refer to the above description, which will not be repeated here. As mentioned above, due to the arrangement in the pump structure 1 (see Figure 3-12 ), when the driving component 200 in the pump body structure 1 is started, the elastic water storage chamber 301 will rotate obliquely around the driving shaft 201 along with the first bracket body 302a. During the rotation process, due to the setting position, material and rotation method of the elastic water storage chamber 301, the elastic water storage chamber 301 will undergo elastic deformation. When the elastic water storage chamber 301 undergoes the first elastic deformation, the volume of the elastic water storage chamber 301 increases, thereby generating suction, so that the water in the water tank 501 is introduced into the elastic water storage chamber 301 through the water inlet channel 101; when the elastic water storage chamber 301 undergoes the second elastic deformation, the volume of the elastic water storage chamber 301 decreases, thereby pushing the water stored in the elastic water storage chamber 301 outward from the elastic water storage chamber 301, so that the water in the elastic water storage chamber 301 is sprayed out through the nozzle 502 through the water outlet channel 102.

[0143] The structural setting of the oral irrigator of the disclosed embodiment can, on the one hand, simplify the manufacturing process, thereby improving the stability of manufacturing precision; on the other hand, it can reduce the noise generated when the oral irrigator is started.
