[0002] A piston pump is a positive displacement pump that relies on the reciprocating motion of a piston within a pump cylinder to transport liquids. Its core working principle is to change the volume of the pump chamber through piston movement, and to achieve the intake and discharge of liquids in conjunction with valves.

[0003] The end cap of the housing, installed at the end of the pump body, is used for heat dissipation and ventilation. While providing ventilation and heat dissipation, it must also prevent the intrusion of external dust and impurities. The end cap is installed on the pump body with screws. If the end cap is damaged during use, such as by impact, dents, or damage to the filter mesh, it will affect its ability to prevent the intrusion of external dust and impurities. Therefore, this invention proposes a piston pump with a reinforced housing structure to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-2 This utility model provides a piston pump with a reinforced shell structure, including a pump body shell end cover body 1 and a mounting ear 11 disposed on the side of the pump body shell end cover body 1; a ventilation groove 2 is also provided in the pump body shell end cover body 1 for heat dissipation and ventilation; the ventilation groove 2 is arranged in an array to improve the uniformity of heat dissipation and avoid local cracking caused by uneven local heating.

[0020] An L-shaped support plate 21 is fixedly installed on the inner side of the pump body housing end cover body 1, and the L-shaped support plate 21 is symmetrically fixedly installed at both ends of the ventilation slot body 2; wherein the L-shaped support plate 21 is used to connect and support the housing auxiliary assembly, and the housing auxiliary assembly is installed in the ventilation slot body 2, and the housing auxiliary assembly is used to provide heat dissipation protection and collision protection for the pump body housing end cover body 1.

[0021] Then according to the appendix Figure 3-4 As shown, a housing auxiliary component is set in the ventilation groove 2 on the pump housing end cover body 1 to achieve a protective function. The arc-shaped frame strip 301 is placed in the ventilation groove 2, and the bearing strip 402 is fixed to the L-shaped support plate 21 by screws. The installation of the arc-shaped frame strip 301 is completed. After installation, the arc-shaped frame strip 301 will exceed the groove position of the ventilation groove 2, that is, the top of the arc-shaped frame strip 301 protrudes from the ventilation groove 2. A protective spring 401 is set at the bottom of the arc-shaped frame strip 301 to achieve a flexible effect.

[0022] This solution features an arc-shaped frame 301 within the ventilation duct 2, with ventilation holes 302 at its top and sides. This not only dissipates heat but also filters out external dust and impurities, enhancing the heat dissipation function of the pump housing end cover 1. Furthermore, a protective spring 401 is installed at the bottom of the arc-shaped frame 301. In the event of a collision, the arc-shaped frame 301 will move towards the ventilation duct 2 to prevent rigid impacts, thus strengthening its performance. The support strip 402 is detachably fixed to the L-shaped support plate 21 with screws, facilitating easy disassembly of the arc-shaped frame 301 and subsequent maintenance or replacement.

[0023] From the appendix Figure 3 As shown, the shell auxiliary component in this solution includes an arc-shaped frame strip 301, within which an arc-shaped cavity 303 is provided. The arc-shaped cavity 303 is connected to the bottom end of the arc-shaped frame strip 301. Ventilation holes 302 are evenly provided at the top and sides of the arc-shaped frame strip 301. These ventilation holes 302 are used for air circulation and for first-stage filtration and blocking of impurities. A filter screen is provided in the arc-shaped cavity 303, positioned close to the ventilation holes 302. This filter screen is used for air circulation and second-stage filtration and blocking of impurities. Secondary filtration can further prevent the intrusion of external dust and impurities. Preferably, the ventilation holes 302 are arranged in an array to improve the uniformity of gas circulation and filtration, and to avoid clogging.

[0024] like Figure 3 As shown, ventilation holes 302 are provided on the arc-shaped frame 301. In addition to providing heat dissipation and ventilation, they can also filter and block external impurities, preventing external dust and impurities from entering the pump body and causing pollution.

[0025] Then from the appendix Figure 4 As shown, for the use of the arc-shaped frame strip 301, this solution also symmetrically fixes a protective spring 401 at the bottom of the arc-shaped frame strip 301, and the other end of the protective spring 401 is fixedly set on the bearing strip 402.

[0026] The purpose of using the protective spring 401 here is to provide flexibility for the arc-shaped frame 301. That is, when the arc-shaped frame 301 is impacted, it will have a flexible contact effect under the action of the protective spring 401, avoiding rigid collisions that could cause impact damage. Furthermore, the arc-shaped frame 301 is installed in the ventilation slot 2, and its initial state is that it protrudes a portion outward from the opening of the ventilation slot 2. At this time, the function of the arc-shaped frame 301 is also to protect the pump body housing end cover body 1, preventing direct collisions with it.

[0027] Furthermore, a mounting hole 403 is provided near the end of the support strip 402; the support strip 402 is fixed to the L-shaped support plate 21 by screws; a through cavity 404 is also provided in the support strip 402; the through cavity 404 is arc-shaped and is used for air circulation. The purpose of providing the through cavity 404 in the support strip 402 is to achieve air circulation and avoid affecting heat dissipation.

[0028] like Figure 4 As shown, mounting holes 403 are provided on the support strip 402, which is fixedly connected to the L-shaped support plate 21 by screws. After the housing auxiliary components are installed, that is, the arc-shaped frame strip 301 is placed into the ventilation slot 2 until the support strip 402 at the bottom of the ventilation slot 2 contacts the L-shaped support plate 21. Then, the support strip 402 is fixed with screws, and the installation of the housing auxiliary components is completed.

[0029] When disassembly is required later, simply disconnect the fixed connection between the bearing strip 402 and the L-shaped support plate 21, and then pull the arc-shaped frame strip 301 out of the ventilation slot 2.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
