Description

Technical Field

[0001] The present invention relates to the technical field of liquid pumps, and more particularly to an improved iron water spray pump body. Background Art

[0002] For example, a Chinese patent with a publication number of CN 211320977U discloses an electric iron with a detachable power supply. The main body of the electric iron is equipped with a water spray head, a water tank and a water spray pump body. The water outlet of the water spray head faces outward, and the water tank, the water spray pump body and the water spray head are connected in sequence through a water pipe. The main body of the electric iron is also provided with a water supply switch group for controlling the action of the water spray pump body. Pressing the water supply switch group can start the water spray pump body, so that the water in the water tank can be sprayed out through the water spray head.

[0003] like Figure 1 As shown, the existing water spray pump body of this type includes a pump body 10 and a piston assembly. The pump body 10 is provided with a water storage chamber 100. The pump body 10 is provided with a water inlet pipe 11 and a water outlet pipe 12 respectively communicating with the water storage chamber 100. A seal 13 is also installed on the water inlet pipe 11. The seal 13 is opened when the pump body pumps water to communicate with the water storage chamber. When the pump body 10 sprays water, the water inlet pipe 11 is sealed to spray the water in the water storage chamber 100 from the water outlet pipe 12. However, since the water added to the iron water tank is usually tap water, there are impurities such as scale in this tap water. When there is water in the pump body and the water spray pump body is not used for a long time, the impurities left after the water evaporates are easy to cause the seal to stick to the water inlet pipe, causing the water inlet pipe to be blocked. To this end, we provide an improved iron water spray pump body. Summary of the invention

[0004] The present invention provides an improved iron water spray pump body, the main purpose of which is to overcome the disadvantages that when there is water in the existing water spray pump body and the water spray pump body is not used for a long time, the impurities remaining after the water evaporates easily cause the sealing element and the water inlet pipe to adhere, causing the water inlet pipe to be blocked.

[0005] The present invention adopts the following technical solution: An improved iron water spray pump body comprises a pump body, wherein a water storage chamber is arranged inside the pump body, a water inlet pipe and a water outlet pipe respectively connected to the water storage chamber are arranged on the pump body, a sealing member is arranged between the water inlet pipe and the water storage chamber, and the pump body is further provided with an elastomer, and under the elastic force of the elastomer, the sealing member does not contact the side wall of the pipe opening of the water inlet pipe.

[0006] Specifically, one end of the water inlet pipe communicating with the water storage chamber forms an expansion groove, and the sealing member is installed in the expansion groove.

[0007] Furthermore, an elastomer installation groove is formed in the water inlet pipe at the bottom of the expansion groove, the elastomer is installed in the elastomer installation groove, the sealing member is supported on the top surface of the elastomer, and there is no contact between the sealing member and the bottom surface of the expansion groove.

[0008] Furthermore, an inverted conical surface is formed at the bottom of the expansion groove, and a gap is provided between the sealing member and the inverted conical surface.

[0009] Furthermore, the improved iron water spray pump body of the present invention also includes a piston assembly, which includes a piston, a piston rod and a pump body spring. The piston is installed inside the water storage chamber, the lower end of the piston rod is connected to the piston, and the upper end extends out of the pump body. The pump body spring is installed in the water storage chamber, the upper end of the pump body spring presses against the lower end of the piston, and the lower end presses against the bottom surface of the water storage chamber.

[0010] Preferably, the sealing element is a steel ball, silicone or rubber.

[0011] Preferably, the elastic body is a spring, silicone or rubber.

[0012] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages: 1. The water spray pump body of the invention has an elastic body added below the seal so that the seal does not contact the side wall of the pipe opening of the water inlet pipe. The elastic body can be compressed by the seal under the action of external force when the water spray pump body sprays water, so that the seal seals the side wall of the pipe opening of the water inlet pipe, which does not affect the water spraying function of the iron water spray pump body. Therefore, the elastic body added by the present invention can prevent the seal from adhering to the side wall of the pipe opening of the water inlet pipe and clogging the water inlet pipe when there is water in the pump body and it is not used for a long time.

[0013] 2. The water spray pump body of the invention has an inverted conical surface formed at the bottom of the expansion groove. When the seal is a steel ball, when the pump body is not working, the seal can fall accurately along the conical surface to the top surface of the elastic member under the action of its own weight to ensure that it does not contact the side wall of the pipe mouth of the water inlet pipe.

[0018] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0019] An improved iron water spray pump body, referring to Figure 2 and Figure 3 , comprising a pump body 10 and a piston assembly. A water storage chamber 100 is provided inside the pump body 10. To facilitate the movement of the piston assembly, the water storage chamber 100 preferably adopts a cylindrical structure.

[0020] Reference Figure 3 and Figure 4 The piston assembly includes a piston 21, a piston rod 22 and a pump body spring 23. The piston 21 is installed inside the water storage chamber 100, and the side wall of the piston 21 is tightly attached to the inner wall of the water storage chamber 100. The lower end of the piston rod 22 is connected to the piston 21, and the upper end extends out of the pump body 10. The pump body spring 23 is installed in the water storage chamber 100, and the upper end of the pump body spring 23 is pressed against the lower end of the piston 22, and the lower end is pressed against the bottom surface of the water storage chamber 100.

[0021] Reference Figure 3 and Figure 4 The pump body 10 is provided with a water inlet pipe 11 and a water outlet pipe 12 respectively connected to the water storage chamber 100. Preferably, the water inlet pipe 11 is arranged at the bottom of the pump body 10, opposite to the piston; and the water outlet pipe 12 is arranged on the side of the pump body 10. An expansion groove 110 is formed at one end of the water inlet pipe 11 connected to the water storage chamber 100, and a sealing member 13 is installed in the expansion groove 110. The sealing member 13 shown in this embodiment is a steel ball.

[0022] Reference Figure 3 The bottom of the pump body spring 23 just rests against the top opening of the expansion groove 110, and the bottom of the pump body spring 23 is in a contracted shape to prevent the steel ball from leaving the expansion groove 110 when the water spray pump body pumps water and fails to play a sealing role.

[0023] Reference Figure 3 An elastic body installation groove 111 is formed in the water inlet pipe 11 at the bottom of the expansion groove 110. An elastic body 14 is installed in the elastic body installation groove 111. The elastic body 14 shown in this embodiment is preferably a spring. The sealing member 13 is supported on the top surface of the elastic body 14, and the sealing member 13 does not contact the bottom surface of the expansion groove 110.

[0024] Reference Figure 3The expansion groove 110 is cylindrical in shape, and the inner diameter of the expansion groove 110 is greater than the diameter of the steel ball, and the height is also greater than the diameter of the steel ball. The bottom of the expansion groove 110 forms an inverted cone surface so that the seal 13 can slide smoothly to the top surface of the elastic body 14.

[0025] A push button (not shown) can be installed on the upper end of the piston rod 22. When in use, the operator manually acts on the push button to move the piston rod inward, pushing the piston to squeeze the pump body spring; when the force acting on the push button disappears, the piston and the piston rod move outward under the action of elastic force, and because the pressure in the water storage chamber is relatively low, the water pushes up the seal along the water inlet pipe and enters the water storage chamber. When the operator presses the push button again to move the piston rod inward, pushing the piston to squeeze the pump body spring, the seal seals the pipe opening of the water inlet pipe under the action of water pressure, and the water in the water storage chamber sprays out from the water outlet pipe.

[0026] The sealing element of the present invention is not limited to steel balls, but can also be made of silicone or rubber. The elastic body is not limited to springs, but can also be made of silicone or rubber.

[0027] The piston rod of the present invention is not limited to being pressed by a pressing key, and can be connected to a power mechanism such as a cylinder.

[0028] The piston rod shown in the above embodiment is installed at the upper part of the pump body, and the water inlet pipe is installed at the bottom of the pump body. Of course, in other embodiments, when the pump body is placed horizontally, the piston rod and the water inlet pipe are respectively located in the left and right directions of the pump body. Therefore, the piston rod and the water inlet pipe are not limited to being installed at the upper part and the bottom of the pump body, as long as they are installed in the axial direction of the pump body.

[0029] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
